| 2 | Differing coping mechanisms, stress level and anorectal physiology in patients with functional constipation显示文摘AIM: To investigate coping mechanisms, constipation symptoms and anorectal physiology in 80 constipated subjects and 18 controls.METHODS: Constipation was diagnosed by Rome Ⅱ criteria.Coping ability and anxiety/depression were assessed by validated questionnaires. Transit time and balloon distension test were performed.RESULTS: 34.5% patients were classified as slow transit type of constipation. The total colonic transit time (56 h vs 10 h, P<0.0001) and rectal sensation including urge sensation (79 mL vs 63 mL, P = 0.019) and maximum tolerable volume (110 mL vs95 mL, P = 0.03) differed in patients and controls. Constipated subjects had significantly higher anxiety and depression scores and lower SF-36 scores in all categories. They also demonstrated higher scores of'monitoring' coping strategy (14+6 vs9+3, P = 0.001),which correlated with the rectal distension sensation (P = 0.005), urge sensation (P=0.002), and maximum tolerable volume (P = 0.035). The less use of blunting strategy predicted slow transit constipation in both univariate (P = 0.01) and multivariate analysis (P = 0.03).CONCLUSION: Defective or ineffective use of coping strategies may be an important etiology in functional constipation and subsequently reflected in abnormal anorectal physiology. | Annie OO Chan Cecilia Cheng Wai Mo Hui Wayne HC Hu Nina YH Wong KF Lam Wai Man Wong Kam Chuen Lai Shiu Kum Lam Benjamin CY Wong | 2005 | World Journal of Gastroenterology2005，11，34： | 92 |

| 5 | APACHE system is better than Ranson system in the prediction of severity of acute pancreatitis显示文摘BACKGROUND: It has been suggested that addition of obesity score to the APACHE-Ⅱ system can lead to more accurate prediction of severity of acute pancreatitis. However there is scanty information on the usefulness of the combined APACHE-O scoring system in Asian patients. This study aimed to compare the accuracy of Ranson, APACHE-Ⅱ and APACHE-O systems in assessing severity of acute pancreatitis in a local Chinese population. METHODS: One hundred and one consecutive patients with acute pancreatitis were prospectively studied. Body mass index (BMI) was measured on admission. Ranson score, APACHE-Ⅱ and APACHE-O scores were recorded on admission and at 48 hours. By adopting the cut-off levels and definitions advocated in the Atlanta consensus for severe disease, the diagnostic accuracy of the three scoring systems was compared by the area under the curve (AUC) under the receiver operator characteristic curve. RESULTS: Of the 101 patients, 12 (11.9%) patients suffered from severe pancreatitis. Obesity was uncommon and only two patients (2.0%) had BMI >30. Eighty-two (81.2%) patients were normal weight (BMI≤25) whereas 17 (16.8%) were overweight ( BMI 25-30 ). Overweight or obesity (BMI >25) was not associated with severe pancreatitis (P= 0.40). The AUC for admission scores of Ranson, APACHE-Ⅱ, and APACHE-O systems was 0. 549, 0. 904 and 0. 904, respectively. The AUC for 48-hour scores of Ranson, APACHE-Ⅱ and APACHE-O systems was 0.808, 0.955 and 0.951, respectively. CONCLUSIONS: The APACHE-Ⅱ scoring system is more accurate than the Ranson scoring system of the prediction of severity in acute pancreatitis. Addition of obesity score does not significantly improve the predictive accuracy of the APACHE-Ⅱ system in our local population with a low prevalence of obesity. | Yuk Pang Yeung Billy Yeung Kit Lam Andrew Wai Chun Yip | 2006 | Hepatobiliary & Pancreatic Diseases International2006，5，2： | 41 |

| 8 | 深圳湾海域氮磷营养盐变化及富营养化特征显示文摘根据1986—2007年深圳湾海水水质监测资料,阐述了氮磷营养盐的变化趋势及其相互关系,并探讨了深圳湾海域富营养化程度。结果表明,深圳湾海域水体溶解态无机氮含量年际变化幅度较大,但总体呈上升趋势。氨氮是溶解态无机氮的主要组成形态,表明深圳湾无机氮处于热力学不平衡状态。深圳湾海域水体中活性磷酸盐值含量变化幅度比较小,总体呈下降趋势。深圳湾水体DIN/P值在1998年以前呈不断上升趋势,1998—2002年之间呈现波动变化,从2002年开始降低,营养盐含量和组成的改变导致浮游植物群落结构的改变,深圳湾海域发生的赤潮生物种类有从硅藻向甲藻过渡,然后从甲藻向硅藻过渡的趋势;相关分析表明,溶解态无机氮以及氮磷营养盐之间的相关关系显著(r=0.769,p<0.01),说明氮磷营养盐间有一定程度相似的生物地球化学过程;水体营养状态质量指数显示深圳湾海水富营养化程度很高,高度富营养化的水体使得深圳湾海域的赤潮日趋频繁,控制入湾水体污染刻不容缓。 | 孙金水 WAI Onyx Wing-Hong 王伟 雷立 毛小苓 | 2010 | 北京大学学报(自然科学版)2010，46，6： | 34 |
| 9 | Helicobacter pylori associated gastric intestinal metaplasia:Treatment and surveillance显示文摘Gastric cancer(GC) is one of the leading causes of cancer related death in the world, particularly in East Asia. According to the Correa's cancer cascade, noncardia GC is usually developed through a series of mucosal changes from non-atrophic gastritis to atrophic gastritis(AG), intestinal metaplasia(IM), dysplasia and adenocarcinoma. Atrophic gastritis and IM are therefore generally considered to be pre-neoplastic gastric lesions. Helicobacter pylori(H. pylori) infection is an important initiating and promoting step of this gastric carcinogenesis cascade. Emerging long-term data showed that eradication of H. pylori reduced the risk of subsequent cancer development. It however remains confusing whether eradication of the bacterium in individuals with pre-neoplastic gastric lesions could regress these changes as well as in preventing cancer. Whilst H. pylori eradication could likely regress AG, the presence of IM may be a point of no return in this cascade. Hence, surveillance by endoscopy may be indicated in those with extensive IM or those with incomplete IM, particularly in populations with high GC risk. The optimal interval and the best tool of surveillance endoscopy remains to be determined in future studies. | Kevin Sze-Hang Liu Irene Oi-Ling Wong Wai K Leung | 2016 | World Journal of Gastroenterology2016，22，3： | 23 |
| 10 | 卡托普利对前壁与下壁心肌梗塞作用差异的临床试验显示文摘报告中国转换酶抑制剂治疗急性心肌梗塞多中心随机双盲安慰剂对照临床试验的一部分,重点探讨卡托普利对前壁与下壁心肌梗塞作用的差异。选择急性心肌梗塞患者12631例,随机分配到卡托普利治疗组或安慰剂对照组,口服卡托普利或安慰剂12.5mg3次/d,治疗4周。结果提示:前壁梗塞(n=6057)治疗组4周病死率(9.2%)明显低于对照组(10.8%),减少死亡危险15%(P=0.04),但下壁梗塞(n=3990)病死率治疗组(7.2%)与对照组(6.7%)差异无显著性(P=0.54)。发病6h内入选前壁梗塞病死率治疗组(9.5%)显著低于对照组(13.2%)(P=0.004),但下壁无此差异。非心动过缓(心率≥60次/分)者总病死率治疗组(9.5%)明显低于对照组(11.5%;P=0.04),在前壁尤为显著(治疗组8.6%;对照组12.5%,P=0.001)。结果表明:卡托普利早期治疗前壁心肌梗塞是安全和有益的,但对下壁则无益。 | (Chinese CEI-AMI Clinical Trial Collaboration Group)(Correspondence: Department of Hypertension, Fu Wai Hospital, CAMS, 100037 Beijing, China) | 1995 | 中华心血管病杂志1995，23，3： | 19 |
| 11 | Effect of oral erythromycin on gastric and small bowel transit time of capsule endoscopy显示文摘AIM: To determine the effect of oral erythromycin on gastric and small bowel transit time of capsule endoscopy.METHODS: Consecutive patients who underwent capsule endoscopy du ring the 16-mo study period were either given 250 mg oral erythromycin, 1 h prior to swallowing the capsule endoscope or nothing. The gastric and small bowel transit time, and the small bowel image quality were compared.RESULTS: Twenty-four patients received oral erythromycin whereas 14 patients were not given any prokinetic agent.Patients who received erythromycin had a significantly lower gastric transit time than control (16 min vs70 min, P= 0.005),whereas the small bowel transit time was comparable between the two groups (227 min vs183 min, P = 0.18).Incomplete small bowel examination was found in three patients of the control group and in one patient of the erythromycin group. There was no significant difference in the overall quality of small bowel images between the two groups. A marked reduction in gastric transit time was noted in two patients who had repeat capsule endoscopy after oral erythromycin.CONCLUSION: Use of oral erythromycin significantly reduces the gastric transit time of capsule endoscopy. | Wai K Leung Francis KL Chan Sara SL Fung Mei-Yin Wong Joseph JY Sung | 2005 | World Journal of Gastroenterology2005，11，31： | 16 |
| 12 | A perturbation-incremental scheme for studying Hopf bifurcation in delayed differential systems显示文摘A new method, called perturbation-incremental scheme (PIS), is presented to investigate the periodic solution derived from Hopf bifurcation due to time delay in a system of first-order delayed differential equations. The method is summarized as three steps, namely linear analysis at critical value, perturba- tion and increment for continuation. The PIS can bypass and avoid the tedious calculation of the center manifold reduction (CMR) and normal form. Meanwhile, the PIS not only inherits the advantages of the method of multiple scales (MMS) but also overcomes the disadvantages of the incremental harmonic balance (IHB) method. Three delayed systems are used as illustrative examples to demonstrate the validity of the present method. The periodic solution derived from the delay-induced Hopf bifurcation is obtained in a closed form by the PIS procedure. The validity of the results is shown by their consis- tency with the numerical simulation. Furthermore, an approximate solution can be calculated in any required accuracy. | CHUNG Kwok Wai | 2009 | Science China(Technological Sciences)2009，52，3： | 15 |
| 13 | Outcome of transarterial chemoembolization in patients with inoperable hepatocellular carcinoma eligible for radiofrequency ablation显示文摘AIM: To evaluate the outcome of transarterial chemoembolization (TACE) in patients with unresectable hepatocellular carcinoma (HCC) <5 cm in diameter eligible for radiofrequency ablation (RFA).METHODS: The treatment-related mortality, morbidity,long-term survival, and prognostic factors of HCC patients who had TACE and fulfilled the present inclusion criteria for RFA were evaluated.RESULTS: Of the 748 patients treated with TACE between January 1990 and December 2002, 114 patients were also eligible for RFA. The treatment-related mortality and morbidity were 1% and 19%, respectively. Survival at 1, 3, and 5 years was 80%, 43%, and 23%, respectively. Older age and a high albumin level were associated with a better survival, whereas a high α-fetoprotein level (AFP) and the size of the largest tumor >3 cm in diameter were adverse prognostic factors in multivariate analysis.CONCLUSION: The morbidity, mortality, and survival data after TACE for small HCCs eligible for RFA are comparable to those reported after RFA in the literature. Our data suggest the need for a randomized comparison of the two treatment modalities for small HCCs. | Mike SL Liem Ronnie TP Poon Chung Mau Lo Wai Kuen Tso Sheung Tat Fan | 2005 | World Journal of Gastroenterology2005，11，29： | 15 |
| 14 | Drug resistance mechanisms and novel drug targets for tuberculosis therapy显示文摘Drug-resistant tuberculosis(TB) poses a significant challenge to the successful treatment and control of TB worldwide.Resistance to anti-TB drugs has existed since the beginning of the chemotherapy era.New insights into the resistant mechanisms of anti-TB drugs have been provided.Better understanding of drug resistance mechanisms helps in the development of new tools for the rapid diagnosis of drugresistant TB.There is also a pressing need in the development of new drugs with novel targets to improve the current treatment of TB and to prevent the emergence of drug resistance in Mycobacterium tuberculosis.This review summarizes the anti-TB drug resistance mechanisms,furnishes some possible novel drug targets in the development of new agents for TB therapy and discusses the usefulness using known targets to develop new anti-TB drugs.Whole genome sequencing is currently an advanced technology to uncover drug resistance mechanisms in M.tuberculosis.However,further research is required to unravel the significance of some newly discovered gene mutations in their contribution to drug resistance. | Md Mahmudul Islam H.M.

| 16 | Effect of Lycium barbarum Polysaccharides on the expression of endothelin-1 and its receptors in an ocular hypertension model of rat glaucoma显示文摘Lycium barbarum, a traditional Chinese anti-aging herb, has been shown to protect retinal ganglion cells (RGCs) in a rat chronic ocular hypertension (COH) model. Here, we investigated the expression of endothelin-1 (ET-1), a strong vasoconstrictor, and its receptors, ETA and ETB, in the COH model and assessed the effects of Lycium barbarum on the ET-1 axis. Elevated intraocular pressure (IOP) was induced in the right eye of SD rats using argon laser photocoagulation. (1) The expression of ET-1, ETA and ETB in normal and COH retinas was studied. (2) Some COH rats were fed daily with Lycium barbarum Polysaccharides (LBP) using 1 mg/kg or phosphate-buffered saline (PBS) for 3 weeks (started 1 week before photocoagulation). The effects of LBP on the expression of ET-1 and its receptors, ETA and ETB, in COH retina were evaluated. A semi-quantitative analysis of staining intensity was used to evaluate the expression levels of ET-1, ETA and ETB in retinal vasculature. We found that (1) Under COH condition, the immunoreactivity of ET-1 was increased in retina associated with an increase of ETB receptor immunoreactivity and a decrease of ETA receptor immunoreactivity. (2) After feeding COH rats with LBP, the expression of ET-1 was decreased with an increase of ETA expression and a decrease of ETB expression in the retina, especially in RGCs. (3) By comparing the staining intensity in the vasculature of COH retina in LBP-fed group with PBS-fed group, there was a decrease in the expression of ET-1 and ETA and an increase in ETB. In summary, ET-1 expression was up-regulated in the retina in COH model. LBP could decrease the expression of ET-1 and modulate the expression of its receptors, ETA and ETB, under the condition of COH. The neuroprotective effect of LBP on RGCs might be related to its ability to regulate the ET-1-mediated biological effects on RGCs and retinal vasculature. | Xue-Song Mi Kin Chiu Geoffrey Van Justin Wai Chung Leung Amy Cheuk Yin Lo SookjaKim Chung Raymond Chuen-Chung Chang Kwok-Fai So | 2012 | Neural Regeneration Research2012，7，9： | 14 |
| 17 | Treatment of functional dyspepsia with sertraline:A double-blind randomized placebo-controlled pilot study显示文摘AIM:To evaluate sertraline,a selective serotonin reuptake inhibitor in the treatment of patients with functional dyspepsia.METHODS:Consecutive tertiary hospital patients with a clinical diagnosis of functional dyspepsia(FD) according to the Rome Ⅱ criteria with a Hong Kong dyspepsia index(HKDI) of greater than 16 were recruited.Patients commenced enrolment prior to the inception of the Rome Ⅲ criteria for functional dyspepsia.All patients were ethnic Chinese,had a normal upper endoscopy and were Helicobacter pylori negative prior to enrolment.Study patients were randomized to receive sertraline 50 mg or placebo daily for 8 wk.HKDI symptom scores,quality of life,hospital anxiety and depression(HAD) scale and global symptom relief were evaluated before,during and after treatment.Adverse effects were monitored during and after treatment.RESULTS:A total of 193 patients were randomized in the intention to treat(ITT),and 150 patients were included in the per protocol(PP) analysis.In both the ITT and PP,there was no difference in the primary outcome of global dyspepsia symptoms between the sertraline and placebo groups at week 8.In the ITT analysis,98 and 95 patients were randomized to the sertraline and placebo groups respectively.A total of 43 patients withdrew from the study(22.3%) by week 8,with 23 of the 24 drop-outs in the sertraline group occurring prior to week 4(95.8%).In contrast,in the placebo arm,11 of 19 patients dropped out by week 4(57.9%).Utilizing the last response carried forward to account for the drop-outs,there were no differences between the sertraline and placebo groups at baseline in terms of the HKDI,HKDI 26.08 ± 6.19 vs 26.70 ± 5.89,P = 0.433;and at week 8,HKDI 22.41 ± 6.36 vs 23.25 ± 7.30,P = 0.352 respectively.In the PP analysis,74 and 76 patients were randomized to the sertraline and placebo groups respectively.At baseline,there were no statistically significant differences between the sertraline and placebo groups,HKDI 25.83 ± 6.313 vs 27.19 ± 5.929 respectively,P = 0.233;however by week 8,patients in the sertraline group demonstrated a statistically significant difference in their Hong Kong Dyspepsia Index compared to placebo,HKDI 20.53 ± 6.917 vs 23.34 ± 7.199,P = 0.02,respectively).There was also no statistically significant difference in overall quality of life measures or the HAD scale related to treatment in either the ITT or PP analysis at week 8.CONCLUSION:This pilot study,the first to examine sertraline,a selective serotonin reuptake inhibitor,for the management of FD,did not find that it was superior to placebo. | Victoria PY Tan Tin K Cheung Wai M Wong Roberta Pang Benjamin CY Wong | 2012 | World Journal of Gastroenterology2012，18，42： | 14 |
| 18 | Assessment of Pb uptake,translocation and immobilization in kenaf (Hibiscus cannabinus L.) for phytoremediation of sand tailings显示文摘The potential of kenaf (Hibiscus cannabinus L.) for phytoremediation of lead (Pb) on sand tailings was investigated.A pot experiment employing factorial design with two main effects of fertilizer and lead was conducted in a nursery using sand tailings from an ex-tin mine as the growing medium.Results showed that Pb was found in the root,stem,and seed capsule of kenaf but not in the leaf.Application of organic fertilizer promoted greater biomass yield as well as higher accumulation capacity of Pb.In Pb-spiked treatments,roots accumulated more than 85% of total plant Pb which implies that kenaf root can be an important sink for bioavailable Pb.Scanning transmission electron microscope (STEM) X-ray microanalysis confirmed that electron-dense deposits located along cell walls of kenaf roots were Pb precipitates.The ability of kenaf to tolerate Pb and avoid phytotoxicity could be attributed to the immobilization of Pb in the roots and hence the restriction of upward movement (translocation factor < 1).With the application of fertilizer,kenaf was also found to have higher biomass and subsequently higher bioaccumulation capacity,indicating its suitability for phytoremediation of Pb-contaminated site. | HO Wai Mun ANG Lai Hoe LEE Don Koo | 2008 | Journal of Environmental Sciences2008，20，11： | 14 |
| 19 | Evaluation of a simulation-based workshop on clinical performance for emergency physicians and nurses显示文摘BACKGROUND: Simulation-based medical education has been growing rapidly and becomes one of the most popular teaching methods for improving patient safety and patient care. The Simulation Subcommittee of the Hong Kong College of Emergency Medicine organized an educational program emphasizing the team training, clinical decision-making and communication skills. This study aimed to evaluate the attitude of the participants toward a new training program and the change in the knowledge on clinical performance in emergency physicians and nurses after attending the educational program.METHODS: A course evaluation form was filled in by the participants at the end of the workshop. An assessment of 20 multiple-choice questions with 5 options was administered to the participants before and after the 2-day simulation-based training workshop.RESULTS: A total of 72 doctors and nurses working in the Accident and Emergency Department were enrolled. The average pretest and posttest scores were 12 and 14.3 respectively. The percentage improvement in the mean score of the pretest and posttest was 11.5%. The Chi-square test showed signifi cant improvement in the pretest and posttest score grading(P=0.00). Paired t-test revealed signifi cant difference between the mean scores of the pretest and posttest(P=0.00).CONCLUSIONS: Participants had positive attitude toward this new training program. Significant improvement of the knowledge on clinical performance in healthcare professionals in the Accident and Emergency Department was observed after the participation in this simulation-based educational program. | Chi Ho Chan Tung Ning Chan Man Cheuk Yuen Wai Kit Tung | 2015 | World Journal of Emergency Medicine2015，6，1： | 14 |
