| 1 | Treatment outcomes for different subgroups of nasopharyngeal carcinoma patients treated with intensity-modulated radiation therapy显示文摘Although many studies have investigated intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC),sample sizes in the reported studies are usually small and different in outcomes in different T and N subgroups are seldom analyzed.Herein,we evaluated the outcomes of NPC patients treated with IMRT and further explored treatment strategy to improve such outcome.We collected clinical data of 865 NPC patients treated with IMRT alone or in combination with chemotherapy,and classified all cases into the following prognostic categories according to different TNM stages:early stage group (T1-2N0-1M0),advanced local disease group (T3-4N0-1M0),advanced nodal disease group (T1-2N2-3M0),and advanced locoregional disease group (T3-4N2-3M0).The 5-year overall survival (OS),local relapse-free survival (LRFS),and distant metastases-free survival (DMFS) were 83.0%,90.4%,and 84.0%,respectively.The early disease group had the lowest treatment failure rate,with a 5-year OS of 95.6%.The advanced local disease group and advanced nodal disease group had similar failure pattern and treatment outcomes as well as similar hazard ratios for death (4.230 and 4.625,respectively).The advanced locoregional disease group had the highest incidence of relapse and death,with a 5-year DMFS and OS of 62.3% and 62.2%,respectively,and a hazard ratio for death of 10.402.Comparing with IMRT alone,IMRT in combination with chemotherapy provided no significant benefit to locoregionally advanced NPC.Our results suggest that the decision of treatment strategy for NPC patients should consider combinations of T and N stages,and that IMRT alone for early stage NPC patients can produce satisfactory results.However,for advanced local,nodal,and locoregional disease groups,a combination of chemotherapy and radiotherapy is recommended. | Sheng-Fa Su 1,2,3,Fei Han 1,2,Chong Zhao 1,2,Ying Huang 1,2,Chun-Yan Chen 1,2,Wei-Wei Xiao 1,2,Jia-Xin Li 1,2 and Tai-Xiang Lu 1,2 1 State Key Laboratory of Oncology in South China,Guangzhou,Guangdong 510060,P.R.China 2 Department of Radiation Oncology,Sun Yat-sen University Cancer Center,Guangzhou,Guangdong 510060,P.R.China 3 Department of Oncology,Guiyang Medical College Hospital,Tumor Hospital of Guizhou,Guiyang,Guizhou 550003,P.R.China. | 2011 | Chinese Journal of Cancer2011,30,8: | 40 |

| 11 | Laparoscopic cystogastrostomy for the treatment of pancreatic pseudocysts: A case report显示文摘Pancreatic pseudocysts(PPs) are collections o pancreatic secretions that are lined by fibrous tissue and may contain necrotic debris or blood. The interventions including percutaneous, endoscopic o surgical approaches are based on the size, location symptoms and complications of a pseudocyst With the availability of advanced imaging system and cameras, better hemostatic equipments and excellent laparoscopic techniques, most pseudocyst can be found and managed by laparoscopy. We describe a case of a 30-year-old male patient with a pancreatic pseudocyst amenable to laparoscopi cystogastrostomy. An incision was made through the anterior gastric wall to expose the posterior gastri wall in close contact with the pseudocyst using an ultrasonically activated scalpel. Then, another incision was made for cystogastrostomy to obtain complete and unobstructed drainage. The patient recovered well after operation and was symptom-free during a 6-mo follow-up, suggesting that laparoscopi cystogastrostomy is a safe and effective alternative to open cystogastrostomy for minimally invasive management of PPs. | Qin-song Sheng Da-Zhi Chen Ren Lang Zhong-Kui Jin Dong-Dong Han Li-Xin Li Yong-Jiu Yang Ping Li Fei Pan Dong Zhang Zhao-Wei Qu Qiang He | 2008 | World Journal of Gastroenterology2008,14,30: | 15 |

| 17 | Efficacy and safety of rituximab therapy for systemic lupus erythematosus:a systematic review and meta-analysis显示文摘Objective:To review the efficacy and safety of rituximab therapy for systemic lupus erythematosus(SLE).Methods:We searched for randomized controlled trails and observational studies that evaluated the effect of rituximab based on the systemic lupus erythematosus disease activity index(SLEDAI),British Isles lupus assessment group index(BILAG),urine protein levels,and the prednisolone dose,and had adequate data to calculate the mean,standard deviation(SD),and 95% confidence intervals,and to systematically review and meta-analyze observational studies with fixed effects model or random effects model.Results:We included 2 randomized controlled studies and 19 observational clinical studies.We summarized the data from the 19 observational studies,analyzed the heterogeneity of the literature,and then used fixed effect model or random effect model for statistical analysis.The SLEDAI,BILAG,and urine protein levels and the prednisolone dosage were decreased after rituximab treatment,and the decreases in the BILAG,urine protein levels,and the prednisolone dose were found to be significant(P<0.05),when compared with baseline level.Rituximab's adverse effects generally could be controlled with an effective dosing regimen.Conclusions:Although there are still controversies about rituximab's treatment on SLE,but our study had showed that rituximab had favorable effects on refractory lupus.The long-term efficacy and safety of rituximab require further study. | Lan LAN Fei HAN Jiang-hua CHEN | 2012 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2012,13,9: | 12 |
| 18 | Spatial and temporal change patterns of net primary productivity and its response to climate change in the Qinghai–Tibet Plateau of China from 2000 to 2015显示文摘The vegetation ecosystem of the Qinghai–Tibet Plateau in China,considered to be the′′natural laboratory′′of climate change in the world,has undergone profound changes under the stress of global change.Herein,we analyzed and discussed the spatial-temporal change patterns and the driving mechanisms of net primary productivity(NPP)in the Qinghai–Tibet Plateau from 2000 to 2015 based on the gravity center and correlation coefficient models.Subsequently,we quantitatively distinguished the relative effects of climate change(such as precipitation,temperature and evapotranspiration)and human activities(such as grazing and ecological construction)on the NPP changes using scenario analysis and Miami model based on the MOD17A3 and meteorological data.The average annual NPP in the Qinghai–Tibet Plateau showed a decreasing trend from the southeast to the northwest during 2000–2015.With respect to the inter-annual changes,the average annual NPP exhibited a fluctuating upward trend from 2000 to 2015,with a steep increase observed in 2005 and a high fluctuation observed from 2005 to 2015.In the Qinghai–Tibet Plateau,the regions with the increase in NPP(change rate higher than 10%)were mainly concentrated in the Three-River Source Region,the northern Hengduan Mountains,the middle and lower reaches of the Yarlung Zangbo River,and the eastern parts of the North Tibet Plateau,whereas the regions with the decrease in NPP(change rate lower than–10%)were mainly concentrated in the upper reaches of the Yarlung Zangbo River and the Ali Plateau.The gravity center of NPP in the Qinghai–Tibet Plateau has moved southwestward during 2000–2015,indicating that the increment and growth rate of NPP in the southwestern part is greater than those of NPP in the northeastern part.Further,a significant correlation was observed between NPP and climate factors in the Qinghai–Tibet Plateau.The regions exhibiting a significant correlation between NPP and precipitation were mainly located in the central and eastern Qinghai–Tibet Plateau,and the regions exhibiting a significant correlation between NPP and temperature were mainly located in the southern and eastern Qinghai–Tibet Plateau.Furthermore,the relative effects of climate change and human activities on the NPP changes in the Qinghai–Tibet Plateau exhibited significant spatial differences in three types of zones,i.e.,the climate change-dominant zone,the human activity-dominant zone,and the climate change and human activity interaction zone.These research results can provide theoretical and methodological supports to reveal the driving mechanisms of the regional ecosystems to the global change in the Qinghai–Tibet Plateau. | GUO Bing ZANG Wenqian YANG Fei HAN Baomin CHEN Shuting LIU Yue YANG Xiao HE Tianli CHEN Xi LIU Chunting GONG Rui | 2020 | Journal of Arid Land2020,12,1: | 12 |
