Objective To evaluate the quality of life of patients with diabetes mellitus in rural areas,and to analyze the main influencing factors.Methods The EQ -5D and questionnaire were used to collect information of patients with diabetes mellitus and to evaluate their quality of life.Logistic regression,multiple liner regression analyses and other statistical methods were used to analyze the related factors of life quality among rural patients with diabetes mellitus. Results A total of 416 patients with diabetes mellitus were investigated.The mean score of EQ -5D and EQ -VAS of all cases were 0.835 ±0.197 and 61.48 ±16.47 respectively,and the rates of the participants had problems at the dimensions of mobility,self -care,usual activities,pain/discomfort and anxiety/depression were 21.15%,11.54%,17.31%, 38.46% and 47.12% respectively.Logistic regressions for the five dimensions showed that complications were the common significant factors of all five dimensions,and age was related to the dimensions of mobility,usual activities,pain/discomfort and anxiety/depression.Gender and HbA1C were influencing factors of pain/discomfort dimension.Multiple liner regression analyses showed that the number of complications was the influencing factors of the valuation of EQ -5D and the score of EQ -VAS.Conclusion The quality of life among patients with diabetes mellitus in rural areas was lower than healthy people.Anxiety/depression was the most common problem,and complications were the main factor for the decrease of quality of life among diabetic patients.

AIM:To assess changes of tear film function in patients after pterygium excision combined with amniotic membrane transplantation.
METHODS:Totally 126 patients with pterygium excision with amniotic membrane transplantation from January 2011 to November 2013 were entered in the study. The tear breakup time ( BUT) , the Schirmer I test ( SⅠt) and tear ferning test ( TFT ) were elevated in the patients before and after pterygium excision combined with amniotic membrane transplantation. The examnation times were 1d before surgey, 1wk, 1, 2mo after surgery. Operation eyes were studied group, while opposite healthy eyes as control group.
RESULTS: Compared with the control group, BUT and TFT were significantly different in the eyes with pterygium (P<0. 05); However, no obvious difference was detected in the results of SⅠt (P>0. 05). The results of BUT and TFT at 1mo after surgery in study group were significantly better than 1wk (P<0. 05), while no significant difference compared with 2mo (P>0. 05); The tear film stability in the study group at 1wk after surgery was still inferior to the control group (P<0. 05) and there was no significant difference at 1, 2mo after surgery (P all>0. 05). SⅠt results did not differ between the different examination times(P>0. 05).
CONCLUSION:Tear film stability was broken in the eyes with pterygium. Pterygium excision combined with amniotic membrane transplantation can obviously restore the tear film function into normal state, and the tear film function could reach steady-state 1mo after surgery.

· METHODS: Three hundred patients ( 300 eyes ) with type 2 diabetes who scheduled for cataract surgery were randomly divided into three groups: group A: 0.3%tobramycin/0. 1% dexamethasone eye drops and pranoprofen eye drops treatment for 1mo postoperatively;group B:intrachamberal injection of TA 1mg after cataract surgery, and 0.5% levofloxacin eye drops treatment for one month postoperatively; group C: intrachamberal injection of TA 2mg after cataract surgery, and 0.5%levofloxacin eye drops treatment for one month postoperatively.The main measurements included visual acuity, intraocular pressure ( lOP ) , corneal endothelial cell density, anterior chamber inflammation and the thickness of macula of the three groups.
· RESULTS:All cataract surgeries were done successfully by a single surgeon.The best corrected vision of group B and C was better than that of group A 1d, 1wk and 1mo postoperatively (P<0.05).The inflammation of anterior chamber of group B and C was milder than that of group A 1d and 1wk postoperatively (P<0.05).The average lOP of group C 1d postoperatively was higher than that of group A (P<0.05).There was no significant difference between group B and group C on the best corrected vision, anterior chamber inflammation and lOP at any time point.No significant change in the macular thickness was found in patients of group B and C before and after cataract surgery, while there was thicker macula in patients of group A 3wk and 1mo postoperatively when comparing with that of the baseline (P<0.05).There was no significant difference among three groups on corneal endothelial cell density at any time point.
· CONCLUSlON: lntrachamberal TA injection during phacoemulsification can effectively control postoperative inflammation, reduce the macular edema and accelerate the recovery of visual acuity.lntrachamberal TA 1mg has good effect and safety.

The study is a paticular embodiment of Chinese patent medicine based on biopharmaceutics classification system of Chinese materia medica (CMMBCS) , focusing on assessment of synchronization issues of dissolution that may affect the timing of the multicomponent absorption. The accumulative dissolution percentages of nine components in Gengen Qinlian tablets in different dissolution solvents and times were determined by HPLC. The dissolution curve was drew and its similarity was evaluated by similarity factors (f2) and cluster method. Results in this experiment showed that the components that peak 7 and peak 8 (baicalin) represented had poor similarity with the reference peak 2 (puerarin). Their similarity factors were both 43 in water dissolution media and 31 and 45 in pH 7.4 dissolution media, respectively. Components that peaks represented had better similarity with the reference peak 2 (puerarin) in other medium. It illustrated that components that peak 3,4,5,6 (berberine) represented had fully synchronous dissolution characteristics with the reference peak 2 (puerarin), components peak 1 and 9 represented had nearly fully synchronous dissolution characteristics with the reference peak 2 (puerarin), while components that peak 7 and 8 (baicalin) represented had no synchronous dissolution characteristics with the reference peak 2 (puerarin).
