| 1 | Ultrasonically activated scalpel versus monopolar electrocautery shovel in laparoscopic total mesorectal excision for rectal cancer显示文摘AIM: To investigate the feasibility and safety of monopolar electrocautery shovel (ES) in laparoscopic total mesorectal excision (TME) with anal sphincter preservation for rectal cancer in order to reduce the cost of the laparoscopic operation, and to compare ES with the ultrasonically activated scalpel (US). METHODS: Forty patients with rectal cancer, who underwent laparoscopic TME with anal sphincter preservation from June 2005 to June 2007, were randomly divided into ultrasonic scalpel group and monopolar ES group, prospectively. White blood cells (WBC) were measured before and after operation, operative time, blood loss, pelvic volume of drainage, time of anal exhaust, visual analogue scales (VAS) and surgery-related complications were recorded. RESULTS: All the operations were successful; no one was converted to open procedure. No significant differences were observed in terms of preoperative and postoperative d 1 and d 3 WBC counts (P = 0.493, P = 0.375, P = 0.559), operation time (P = 0.235), blood loss (P = 0.296), anal exhaust time (P = 0.431), pelvicdrainage volume and VAS in postoperative d 1 (P = 0.431, P = 0.426) and d 3 (P = 0.844, P = 0.617) between ES group and US group. The occurrence of surgery-related complications such as anastomotic leakage and wound infection was the same in the two groups. CONCLUSION: ES is a safe and feasible tool as same as US used in laparoscopic TME with anal sphincter preservation for rectal cancer on the basis of the skillful laparoscopic technique and the complete understanding of laparoscopic pelvic anatomy. Application of ES can not only reduce the operation costs but also benef it the popularization of laparoscopic operation for rectal cancer patients. | Bao-Jun Zhou, Wei-Qing Song, Qing-Hui Yan, Jian-Hui Cai, Feng-An Wang, Jin Liu, Guo-Jian Zhang, Guo-Qiang Duan, Zhan-Xue Zhang, Department of Gastrointestinal Surgery, The Second Hospital of Hebei Medical University, Shijiazhuang 050000, Hebei Province, China Author contributions: Zhou BJ, Song WQ, Yan QH, Cai JH, Wang FA, Liu J, Zhang GJ, Duan GQ and Zhang ZX contributed equally to this work Zhou BJ, Song WQ, Yan QH, Cai JH and Wang FA designed the research Zhou BJ, Liu J and Zhang GJ performed the research Duan GQ and Zhang ZX analyzed the data and Zhou BJ, Song WQ and Yan QH wrote the paper. | 2008 | World Journal of Gastroenterology2008,14,25: | 25 |
| 2 | Report on Childhood Obesity in China (9): Sugar-sweetened Beverages Consumption and Obesity显示文摘Objective To explore the associations between sugar-sweetened beverage (SSB) consumption and obesity as well as obesity-related cardiometabolic disorders among children in China. Methods A total of 6974 (boys 3558, girls 3412) children aged 6-13 years participated in the study. Each participant's height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio (95% confidence internal (CI)] of obesity was 7.6% [as the reference group (ref.)], 10.1% [1.36(1.07, 1.74)], and 11.6% [1.46(1.21, 1.75)], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio (95% CI): 1.36 (1.17, 1.59)]. The prevalence [adjusted odds ratio (95% CI)] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00(1.31, 3.07)], 12.7% [1.52(1.23, 1.88)], 11.5% [1.52(1.18, 1.95)], and 10.4% [1.41(1.03, 1.94)], respectively, which was higher than that of regular milk drinkers [7.6 % (ref.)]. The prevalence [adjusted odds ratio (95% CI)] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55(1.26, 1.90)], 16.2% [1.36(1.09, 1.70)], and 15.3% [1.24(1.03, 1.50)], respectively, which was much higher than that of regular milk drinkers [12.8% (ref.)]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design. | SHANG Xian Wen LIU Ai Ling ZHANG Qian HU Xiao Qi DU Song Ming MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin LI Ting Yu MA Guan Sheng | 2012 | Biomedical and Environmental Sciences2012,25,2: | 23 |

| 5 | How Work Organization Affects the Prevalence of WMSDs: A Case-control Study显示文摘Objective In this study, we aimed at exploring the association between work-related musculoskeletal disorders(WMSDs) and work organization based on a case-control study. Methods A total of 1938 workers who claimed to suffer from WMSDs were selected from Beijing, Henan, Hubei, and the Guangdong province. The control group consisted of 2009 workers employed in similar industries without severe disease or musculoskeletal discomforts. We used a modified version of the questionnaire developed by the NMQ and the DMQ to investigate individual and work-related factors. Results A total of 13 variables(P<0.1) were selected by the chi-square test and finally, 7 variables entered into the equation, with 6 variables reaching statistical significance(P<0.05). The odds ratios(OR) of ‘work changing with season' and ‘sufficient rest time' did not reach 1(0.749 and 0.441, respectively). In addition, ‘sufficient rest time' seemed to be the stronger protective factor according to its higher standardized coefficient. And ‘repetitive work every minute', ‘constantly repetitive work'(every day), ‘shortage of site personnel', and ‘often switching shifts with others' seemed to be the risk factors. Conclusion Work organization may have comprehensive effects on the occurrence of WMSDs. This pattern of associations suggests that further investigation into the mechanism of how work organization affects the prevalence of WMSDs is required. | LIU Lu CHEN Song Gen TANG Shi Chuan WANG Sheng HE Li Hua GUO Ze Hua LI Jing Yun YU Shan Fa WANG Zhong Xu | 2015 | Biomedical and Environmental Sciences2015,28,9: | 11 |

| 8 | Influence of Inclusion on Crack Initiation in Wheel Rim显示文摘Speed increase and heavy haul of the railway freight car are the effective measures to raise the transport ability of railway,and they have been the new trend for railway freight car development.The increase of speed and axle load will lead to the increase of wheel-rail contact stress,which will make a great change of stress distribution in the whole wheel rim.Goodier equation was employed to analyze the stress state around inclusion and cavity.In the operation of wheel-rail contact stress,stress concentration occurred in the pole of Al2O3 spherical inclusion,while it appeared on the equator of cavity.The critical inclusion sizes of 250 kN axle load freight car wheel at different velocities,a certain distance away from the tread,were calculated by Murakami equation.Comparing the inclusion in cast steel wheel with that in rolled steel wheel,it is found that the inclusion in cast steel wheel has much more excellent crack resistance than that in rolled steel wheel.In the meantime,in order to reduce the probability of rim crack,some suggestions were put forward. | MI Guo fa NAN Hong yan LIU Yan-lei ZHANG Bin ZHANG Hong SONG Guo xiang | 2011 | Journal of Iron and Steel Research(International)2011,18,1: | 8 |
| 9 | Alterations to biological soil crusts with alpine meadow retrogressive succession affect seeds germination of three plant species显示文摘Biological soil crusts(BSCs) are the important components of alpine meadow ecosystems.The extent and morphology of BSCs vary greatly with alpine meadow retrogressive succession due to grazing pressure.There is significant interest in impacts of crust composition on plant seed germination,especial l y in(semi-) arid environments.However,little is known about the influences of BSCs,and their associations with alpine meadow succession,on germination of typical alpine meadow vascular plant species.In a full factorial common-gardenexperiment,we studied effects of:(1) crust type,(2) seed position,and(3) surface texture on seed germination.We chose three typical alpine meadow plant species(i.e.Poa pratensis,Tibetia himalaica and Potentillen nivea),which belonged to different functional groups(graminoids,legumes,and forbs) and play important roles in all alpine meadow succession stages.Crust type and seed position influenced seed germination,and the inhibitory effects of BSCs depended on the crust type and seed species tested.The major factors influencing seed germination were BSC type,seed position,soil texture,and the interactions between BSC type and seed position; species and seed position; species andsurface texture; and species,crust type,and surface texture.Cyanobacteria crust significantly inhibited germination of all seeds.Seed position also had a significant effect on seed germination(p < 0.001).Fewer seedlings germinated on the surface than below the surface,this was especially true for P.nivea.seeds within cyanobacteria and lichen crusts.Only germination rates of T.himalaica on the soil surface were significantly correlated with plant occurrence frequency within the alpine meadow community.The poor correlation for the other two species is possibly that they are perennials.Our results clearly demonstrated that BSCs can be biological filters during seed germination,depending on the BSC succession stage.Through their influences on seed germination,BSCs can strongly influence community assemblages throughout alpine meadow retrogressive succession. | LI Yi-kang OUYANG Jing-zheng LIN Li XU Xing-liang ZHANG Fa-wei DU Yan-gong LIU Shu-li CAO Guang-min HAN Fa | 2016 | Journal of Mountain Science2016,13,11: | 7 |
| 10 | Comparative genomic and transcriptomic analyses uncover the molecular basis of high nitrogen-use efficiency in the wheat cultivar Kenong 9204显示文摘Studying the regulatory mechanisms that drive nitrogen-use efficiency(NUE)in crops is important for sustainable agriculture and environmental protection.In this study,we generated a high-quality genome assembly for the high-NUE wheat cultivar Kenong 9204 and systematically analyzed genes related to nitrogen uptake and metabolism.By comparative analyses,we found that the high-affinity nitrate transporter gene family had expanded in Triticeae.Further studies showed that subsequent functional differentiation endowed the expanded family members with saline inducibility,providing a genetic basis for improving the adaptability of wheat to nitrogen deficiency in various habitats.To explore the genetic and molecular mechanisms of high NUE,we compared genomic and transcriptomic data from the high-NUE cultivar Kenong 9204(KN9204)and the low-NUE cultivar Jing 411 and quantified their nitrogen accumulation under high-and low-nitrogen conditions.Compared with Jing 411,KN9204 absorbed significantly more nitrogen at the reproductive stage after shooting and accumulated it in the shoots and seeds.Transcriptome data analysis revealed that nitrogen deficiency clearly suppressed the expression of genes related to cell division in the young spike of Jing 411,whereas this suppression of gene expression was much lower in KN9204.In addition,KN9204 maintained relatively high expression of NPF genes for a longer time than Jing 411 during seed maturity.Physiological and transcriptome data revealed that KN9204 was more tolerant of nitrogen deficiency than Jing 411,especially at the reproductive stage.The high NUE of KN9204 is an integrated effect controlled at different levels.Taken together,our data provide new insights into the molecular mechanisms of NUE and important gene resources for improving wheat cultivars with a higher NUE trait. | Xiaoli Shi Fa Cui Xinyin Han Yilin He Long Zhao Na Zhang Hao Zhang Haidong Zhu Zhexin Liu Bin Ma Shusong Zheng Wei Zhang Jiajia Liu Xiaoli Fan Yaoqi Si Shuiquan Tian Jianqing Niu Huilan Wu Xuemei Liu Zhuo Chen Deyuan Meng Xiaoyan Wang Liqiang Song Lijing Sun Jie Han Hui Zhao Jun Ji Zhiguo Wang Xiaoyu He Ruilin Li Xuebin Chi Chengzhi Liang Beifang Niu Jun Xiao Junming Li Hong-Qing Ling | 2022 | Molecular Plant2022,15,9: | 6 |

| 12 | Comparison of Histological, Microbiological, and Molecular Methods in Diagnosis of Patients with TBLN Having Different Anti-TB Treatment Background显示文摘Objective The influence of anti-tuberculosis(TB) treatment history on tuberculous lymphadenitis(TBLN) diagnosis is unclear. Therefore, this study aims to evaluate the diagnostic methods, including histology, microbiology, and molecular tests, used for TBLN. Methods In this study, suspected patients with TBLN and having different anti-TB treatment background were enrolled. All the samples were tested simultaneously by histology, Ziehl-Neelsen(ZN) staining, mycobacterial culture(culture), Xpert MTB/RIF(xpert), real-time PCR, and high-resolution melting curve PCR(HRM). Thereafter, the performance of these methods on samples with different anti-TB treatment background was assessed. Results In our study, 89 patients were prospectively included 82 patients with TBLN and 7 with other diseases. The overall sensitivities of Xpert, real-time PCR, histology, ZN staining, and culture were 86.6%, 69.5%, 58.5%, 43.9%, and 22.0%, respectively. The anti-TB treatment history revealed dramatic influences on the sensitivity of culture(P < 0.0001). In fact, the treatment that lasted over 3 months also influenced the sensitivity of Xpert(P < 0.05). However, the treatment history did not affect the performance of remaining tests(P > 0.05). For rifampicin drug susceptibility test(DST), the anti-TB treatment showed only significant influence on the success rate of culture DST(P = 0.001), but not on those of Xpert and HRM tests(P > 0.05). Conclusion Other tests as well as culture should be considered for patients with TBLN having retreatment history or over 1-month treatment to avoid false negative results. | CHE Nan Ying HUANG Shao Jun MA Yan HAN Yi LIU Zi Chen ZHANG Chen MU Jing ZHAO Dan QU Yang ZHANG Hai Qing LIU Zhi Dong XU Shao Fa | 2017 | Biomedical and Environmental Sciences2017,30,6: | 6 |

| 14 | Diagenesis and Diagenetic Evolution of Deltaic and Neritic Gas-Bearing Sandstones in the Lower Mingyuefeng Formation of Paleogene, Lishui Sag, East China Sea Shelf Basin: Implications for Depositional Environments and Sequence Stratigraphy Controls显示文摘Gas-bearing deposits in the Lower Mingyuefeng Formation of Paleogene, Lishui Sag, East China Sea Shelf Basin consist of shoreface sandstones of the highstand systems tract(HST) and transgressive systems tract(TST), and deltaic sandstones of the lowstand systems tract(LST) and falling stage systems tract(FSST).Detailed petrographic observations suggest that the diagenetic features and related evolution of these deposits cannot be simply characterized and demonstrated in the depth domain.However, the occurrence of diagenetic minerals systematically depends on the studied interval within the HST, TST, LST, and FSST; therefore, diagenesis in this region can be better constrained when studied in the context of the depositional environments and sequence stratigraphic framework.The eogenetic processes in such settings include:(1) microcrystalline siderite precipitated as concretions in almost all environments and systems tracts, which inhibited further mechanical compaction;(2) grain dissolution and kaolinitization occurred in shoreface HST sandstones and deltaic LST and FSST sandstones;(3) glaucony was locally observed, which did not clearly reflect the controls of facies or sequence stratigraphy; and(4) cementation by pyrite aggregates occurred in the shoreface HST sandstones and deltaic LST sandstones.The mesogenetic diagenesis includes:(1) partial conversion of kaolinite into dickite in deltaic LST sandstones, and minor chlorite cementation in deltaic FSST sandstones;(2) transformation of kaolinite into illite and quartz cementation in deltaic LST and FSST sandstones;(3) frequent precipitation of ankerite and ferroan calcite in shoreface TST sandstones and early HST sandstones, forming baffles and barriers for fluid flow, with common calcite in shoreface HST sandstones as a late diagenetic cement; and(4) formation of dawsonite in the deltaic LST and FSST sandstones, which is interpreted to be a product of the invasion of a CO2-rich fluid, and acts as a good indicator of CO2-bearing reservoirs.This study has thus constructed a reliable conceptual model to describe the spatial and temporal distribution of diagenetic alterations.The results may provide an entirely new conceptual framework and methodology for successful gas exploration in the continental margins of offshore China, thus allowing us to predict and unravel the distribution and quality evolution of clastic reservoirs at a more detailed and reliable scale. | XU Fa ZHANG Penghui ZHANG Jinliang LIU Jinshui HOU Guowei ZHANG Ming LI Jingzhe LIU Shasha GUO Jiaqi MENG Ningning | 2015 | Acta Geologica Sinica(English Edition)2015,89,5: | 5 |

| 16 | Highly luminescent and stable lead-free cesium copper halide perovskite powders for UV-pumped phosphor-converted light-emitting diodes显示文摘Lead halide perovskites have drawn extensive attention over recent decades owing to their outstanding photo-electric performances.However,their toxicity and instability are big issues that need to be solved for further commercialization.Herein,we adopt a facile dry ball milling method to synthesize lead-free Cs3Cu2X5(X=I,CI)perovskites with photoluminescence(PL)quantum yield up to 60%.The optical features including broad emission spectrum,large Stokes shift,and long PL lifetime can be attributed to self-trapped exciton recombination.The as-synthesized blue emissive Cs3Cu2I5 and green emissive Cs3Cu2Cl5 lead-free perovskite powders have good thermal stability and photostability.Furthermore,UV-pumped phosphor-converted light-emitting diodes were obtained by using Cs3Cu2I5 and Cs3Cu2Cl5 as phosphors. | LINGLING XIE BINGKUN CHEN FA ZHANG ZHENG ZHAO XINXIN WANG LIJIE SHI YUE LIU LINGLING HUANG RUIBIN LIU BINGSUO ZOU YONGTIAN WANG | 2020 | Photonics Research2020,8,6: | 5 |
| 17 | Geochemistry of the Paleocene Clastic Rocks in Lishui Sag, East China Sea Shelf Basin: Implications for Tectonic Background and Provenance显示文摘The Lishui Sag,in the East China Sea Shelf Basin,is rich in hydrocarbons,with the major hydrocarbon-bearing layers being the Paleocene Mingyuefeng clastic rocks.Analysis of the implicit geologic background information of these Paleocene clastic rocks using petrological and geochemical methods has significant practical importance.These Paleocene sandstones are mainly lithic arenite,lithic arkose and greywacke,composed of K-feldspar,plagioclase,authigenic clays,silica and carbonates.As continental deposits,Yueguifeng clastic rocks have high aluminosilicate and mafic detritus contents,while the Lingfeng and Mingyuefeng Formations are rich in silica due to an oscillating coastal marine depositional environment The major element contents of these Paleocene sandstones are low and have a concentrated distribution,indicating that the geochemical composition is non-epigenetic,transformed by sedimentary processes and diagenesis.The Yueguifeng detritus comprises recycled sediments,controlled by moderate weathering and erosion,while the Lingfeng and Mingyuefeng detritus is interpreted as primarily first-cycle materials due to low chemical weathering.In the Late Cretaceous to Early Paleocene,the Pacific Plate began subducting under the Eurasian Plate,causing an orogeny by plate collision and magma eruption due to the melting of subducted oceanic crust.This resulted in the dual tectonic settings of'active margin'and'continental island arc'in the East China Sea Shelf Basin.During the Late Paleocene,the Pacific Plate margin migrated eastward along with development of the Philippine Ocean Plate,and the tectonic setting of the Lishui Sag gradually turned into a passive continental margin.Detrital sources included both orogenic continental blocks and continental island arcs,and the parent rocks are primarily felsic volcanic rocks and granites. | LI Deyong JIANG Xiaodian XU Fa LIU Jinshui HOU Guowei | 2016 | Acta Geologica Sinica(English Edition)2016,90,1: | 4 |
| 18 | Effect and mechanism of acute graft versus host disease on early diffuse murine lung injury following allogeneic stem cell transplantation显示文摘To explore the effect and pathogenssis of acute graft-versus-host disease (aGVHD) on early diffuse lung injury in allogeneic hematopoietic stem cell transplantation (allo-HSCT), we established an aGVHD model of C57BL/6→BALB/c mice. Chest computed tomography (CT) scans, histopathology and the levels of cytokines including tumor necrosis factor α (TNFα) and Interferon (IFNγ) in lungs were dynamically detected in recipient mice after transplantation. The incidence of aGVHD was respectively 0%, 0% and 100% in simple irradiation group (A), syngeneic transplant group(B) and allogeneic transplant group (C). Chest CT scans of recipient mice were normal in 3 groups on days +3 and +7 after transplantation. CT showed that two of ten mice had bilateral lung diffuse infiltrate on day +12 (on the brink of death) in group A and 6 of 10 mice had bilateral lung diffuse infiltrate on day +14 (3 d after aGVHD occurring) in group C, and were normal on days +12 and +14 in group B after transplantation. Histopathology of lungs in the 3 groups was similar, consisting of minor interstitial pneumonitis on day +3. Group A showed edema, hyperplasia of epithelial cells and widened alveolar interval on day +7, and epithelial cell necrosis, lymphocyte infiltration, hemorrhage, protein leakage, and local consolidation on day +12. The histopathology of group B showed slight edema of epithelial cells on +7 day, which were slighter than that on day +3, and virtually normal on day +14. The histopathology in group C was characterized by the significant expansion and congestion of capillaries, and lymphocyte infiltration on day +7, the acute pneumonitis was present involving tissue edema, lymphocyte and macrophage infiltration, protein leakage and perivascular inflammation on day +14. In group A, the levels of TNFα were lower on day +7 than on day +3. In group B, the levels of TNFα attained a peak on day +3, which decreased on days +7 and +14. In group C, the levels of TNFα were highest on day +7 and there was a significant difference between those on days +7 and +14 (P=0.816). In group A, the levels of IFNγ on day +7 were higher than on day +3. In group B, the levels of IFNγ increased progressively, but the comparison of IFNγ levels in different times had no statistical significance (P=0.521, 0.118, 0.340). In group C, the levels of IFNγ attained a peak by day +7 and decreased on day +14. aGVHD is the main cause of early non-infectious lung injury. T lymphocytes and TNFα are possibly implicated in the pathogenesis of acute GVHD-induced lung injury. The decreased levels of IFNγ in lung tissues following transplantation might be associated with pulmonary fibrosis in late non-infectious pulmonary complications. | NING Juan, LIU Qi Fa, LUO Xiao Dan, FAN Zhi Ping & Zhang Yu Department of Hematology, Southern Hospital, Southern Medical University, Guang Zhou 510515, China | 2009 | Science China(Life Sciences)2009,52,11: | 4 |
| 19 | Clinical practice guideline for transurethral plasmakinetic resection of prostate for benign prostatic hyperplasia(2021 Edition)显示文摘Benign prostatic hyperplasia (BPH) is highly prevalent among older men, impacting on their quality of life, sexual function, and genitourinary health, and has become an important global burden of disease. Transurethral plasmakinetic resection of prostate (TUPKP) is one of the foremost surgical procedures for the treatment of BPH. It has become well established in clinical practice with good efficacy and safety. In 2018, we issued the guideline “2018 Standard Edition”. However much new direct evidence has now emerged and this may change some of previous recommendations. The time is ripe to develop new evidence-based guidelines, so we formed a working group of clinical experts and methodologists. The steering group members posed 31 questions relevant to the management of TUPKP for BPH covering the following areas: questions relevant to the perioperative period (preoperative, intraoperative, and postoperative) of TUPKP in the treatment of BPH, postoperative complications and the level of surgeons’ surgical skill. We searched the literature for direct evidence on the management of TUPKP for BPH, and assessed its certainty generated recommendations using the grade criteria by the European Association of Urology. Recommendations were either strong or weak, or in the form of an ungraded consensus-based statement. Finally, we issued 36 statements. Among them, 23 carried strong recommendations, and 13 carried weak recommendations for the stated procedure. They covered questions relevant to the aforementioned three areas. The preoperative period for TUPKP in the treatment of BPH included indications and contraindications for TUPKP, precautions for preoperative preparation in patients with renal impairment and urinary tract infection due to urinary retention, and preoperative prophylactic use of antibiotics. Questions relevant to the intraoperative period incorporated surgical operation techniques and prevention and management of bladder explosion. The application to different populations incorporating the efficacy and safety of TUPKP in the treatment of normal volume (< 80 ml) and large-volume (≥ 80 ml) BPH compared with transurethral urethral resection prostate, transurethral plasmakinetic enucleation of prostate and open prostatectomy;the efficacy and safety of TUPKP in high-risk populations and among people taking anticoagulant (antithrombotic) drugs. Questions relevant to the postoperative period incorporated the time and speed of flushing, the time indwelling catheters are needed, principles of postoperative therapeutic use of antibiotics, follow-up time and follow-up content. Questions related to complications incorporated types of complications and their incidence, postoperative leukocyturia, the treatment measures for the perforation and extravasation of the capsule, transurethral resection syndrome, postoperative bleeding, urinary catheter blockage, bladder spasm, overactive bladder, urinary incontinence, urethral stricture, rectal injury during surgery, postoperative erectile dysfunction and retrograde ejaculation. Final questions were related to surgeons’ skills when performing TUPKP for the treatment of BPH. We hope these recommendations can help support healthcare workers caring for patients having TUPKP for the treatment of BPH. | Xian-Tao Zeng Ying-Hui Jin Tong-Zu Liu Fang-Ming Chen De-Gang Ding Meng Fu Xin-Quan Gu Bang-Min Han Xing Huang Zhi Hou Wan-Li Hu Xin-Li Kang Gong-Hui Li Jian-Xing Li Pei-Jun Li Chao-Zhao Liang Xiu-Heng Liu Zhi-Yu Liu Chun-Xiao Liu Jiu-Min Liu Guang-Heng Luo Yi Luo Wei-Jun Qin Jian-Hong Qiu Jian-Xin Qiu Xue-Jun Shang Ben-Kang Shi Fa Sun Guo-Xiang Tian Ye Tian Feng Wang Feng Wang Yin-Huai Wang Yu-Jie Wang Zhi-Ping Wang Zhong Wang Qiang Wei Min-Hui Xiao Wan-Hai Xu Fa-Xian Yi Chao-Yang Zhu Qian-Yuan Zhuang Li-Qun Zhou Xiao-Feng Zou Nian-Zeng Xing Da-Lin He Xing-Huan Wang 无 | 2022 | Military Medical Research2022,9,5: | 4 |
| 20 | Prostatic anatomical parameters correlate with clinical characteristics suggestive of benign prostatic hyperplasia显示文摘We conducted the present study to assess the correlation of the prostatic anatomical parameters,especially the ratio of peripheral zone thickness and transitional zone thickness,with clinical and uroflowmetry characteristics suggestive of benign prostate hyperplasia(BPH).A total of 468 consecutive patients with a detailed medical history were identified.All patients were evaluated by scoring subjective symptoms with the International Prostate Symptom Score(IPSS)and quality of life(QoL).The prostatic anatomical parameters were measured using transrectal ultrasonography,and postvoid residual urine and maximum flow rate(Q_(max))values were also determined.Pearsonfs correlation analysis revealed that both total prostate volume(TPV;r=0.160,P<0.001)and transitional zone volume(TZV;r=0.104,P=0.016)increased with patients7 age;however,no correlations were observed of TPV,TZV,transitional zone index(TZI),and transitional zone thickness(TZT)with IPSS or QoL(all P>0.05).Peripheral to transitional zone index(PTI)was found negatively correlated with total IPSS(r=-0.113,P=0.024),storage IPSS(r=-0.103,P=0.041),and voiding IPSS(r=-0.123,P-0.014).As regards the uroflowmetry characteristics,PTI(r=0.157,P=0.007)was indicated to be positively correlated with Q_(max)and negatively correlated with TZI(r=-0.119,P=0.042)and TZT(r=-0.118,P=0.045),but not correlated with TPV,TZV,or peripheral zone thickness(PZT)(all P>0.05).Postvoid residual urine(PVR)had not correlated with all the prostatic anatomical variables(all P>0.05).This is the first study that formally proposed the concept of PTI,which is an easy-to-measure prostate anatomical parameter which significantly correlates with total IPSS,storage IPSS,voiding IPSS,and Q_(max),suggesting that PTI would be useful in evaluating and managing men with lower urinary tract symptoms(LUTS)/BPH.However,well-designed studies are mandatory to verify the clinical utility of PTI. | Ye Tian Hong-Ming Liu Bing Yang Xiu-Shu Yang Zhao-Lin Sun Fa Sun Guang-Heng Luo Shu-Jie Xia | 2021 | Asian Journal of Andrology2021,23,1: | 4 |
