A new ion chromatography was developed for the determination of clodronate disodium and its related substances. A suppressed conductivity detection was used. The analytical column was an IonPac AS11-HC anion-exchange column. The column temperature was maintained at 30 ℃. The potassium hydroxide solution was used as the eluent at a flow rate of 1.2 mL/min. For the determination of content and related substances,an isocratic elution program and a gradient elution program were performed, respectively.A good linear relationship was observed in the concentration range of clodronate disodium of 0.0568-0.1895 g/L(r=0.9999). The average recoveries of the injection and the capsules were 100.1%(RSD=0.7%) and 98.9%(RSD=0.6%),respectively. The limit of detection was 0.3 ng. The related substances gained a completely chromatography separation with the principal peak. The present method is accurate, sensitive and simple, which provides a new reliable analytical method for the quality control of clodronate disodium and its preparations.

Objective To determine the reliability, validity and feasibility of using International Classifica-tion of Functioning, Disability and Health (ICF) core set for breast cancer in Chinese patients. Methods Quality of life (QOL) of 110 patients with breast cancer were investigated using ICF breast cancer core set and SF-36 scale. Statistical analysis tested their reliability, validity and feasibility. Results It was shown that the ICF core set for breast cancer had good reliability, validity and feasibility. Conclusions The ICF core set for breast cancer is a re-liable and valid instrument for Chinese breast cancer patients.

Objective To explore the effects ofDoctor-nurse Integratingmode on the operation room nursing quality improvement. Methods From July 2014 to Dec. 2014,11 423 operations in our hospital were chosen as control group,while 10 897 operations from Jan. 2015 to June 2015 as intervention group.An administrating group of Doctor-nurse Integrating mode was formed, with both doctors and nurses acting as quality controllers. A144 Regular Meetings System was also formed. The author retrospected and analyzed 11 423 negative accidents which occurred during operation. Management details and responsibilities were specified, and training was enhanced. All these were monitored, controlled, implemented and improved by operation doctors, anaesthesia doctors and operation room nurses. Results The rate of negative accidents dropped from 1.226%(140/11 423) to 0.340%(37/10 897) since the implementation of Doctor-nurse Integrating mode of operation quality control. Conclusions Doctor-nurse Integrating mode of operation quality control has positive effects on the improvement of operation nursing quality.

Objective To explore the feasibility of endoscopic thyroidectomy without the use of ultrasonic scalpel.Methods Monopolar high frequency electrosurgical unit was used to complete endoscopic thyroidectomy in 6 cases of thyroid benign tumors.Results All the operations were completed successfully.The operation time was 80~200 min(mean,110 min) and the intraoperative blood loss was 25~50 ml(mean,36 ml).The patients got out-of-bed activities and took liquid diets at a mean of 24 hours postoperatively.No complications was found.The drainage tube was removed on 2 days after operation and the patients were discharged from hospital at 3~5 days.Conclusions Use of high frequency electrosurgical unit for endoscopic thyroidectomy is safe and feasible.

Objective:To observe efficacy of Weichangshu in treatment of diabetic gastroparesis(DGP).Methods:96 cases of DGP conformed with the criteria were randomly divided into two groups.They were treated by oral administration of Weichangshu and Mosapride respectively for 4 weeks in addition to original treatment program for controlling blood sugar.Changes of clinical symptoms,FBG and P2hBG,gastric antrum-duodenum interdigestive period migrating motion compound wave(MMC)and electrogastrogram(EGG)before and after treatment were investigated.Results:Clinical symptoms were significantly improved in both groups.The markedly effective rate was 62.50% and the total effective rate was 91.67% in the Weichangshu group,and the corresponding index was 60.42% and 89.58% in the Mosapride group.After treatment,MMC significantly improved in both groups,with significant differences in lasting time of phase Ⅱ,and phase Ⅲ,and the contraction amplitude as compared with those before treatment(P

AIM:To investigate changes of retinal nerve fiber layer ( RNFL) thickness and macular retinal thickness in patients with early diabetic retinopathy ( DR ) and disclose the changing trends of RNFL thickness and macular retinal thickness in different stages of early DR.
METHODS:It was a clinical case control study. Through selecting 60 patients ( 120 eyes ) with early DR diagnosed with type 2 diabetes were divided into non - diabetic retinopathy (NDR) group (20 cases, 40 eyes) and mild non-proliferative diabetic retinopathy (NPDR) group (20 cases, 40eyes), moderate NPDR group (20 cases, 40 eyes) . Twenty normal patients ( 40 eyes ) were enrolled as control group. The RNFL thickness of optical nerve ( with circle scan round optic nerve head, scan diameter of 3. 45mm) and the retinal thickness of macular ( around center point with 1000μm diameter ) were measured by optical coherence tomography ( OCT ) , to compare the RNFL thickness changes of the control and early DR patients.
RESULTS:Compared with the control group, the RNFL thickness of optical disc in the inferior quadrant was descended obviously in NDR group ( P < 0. 05 ), with statistically significant difference,; there were no statistically significant difference in other quadrants ( P>0.05). In mild NPDR group, the RNFL thickness of optical disc in the mean and inferior quadrant was significantly descended than that in the NDR group. In moderate NPDR group, the RNFL thickness of optical disc in the mean, superior and inferior quadrant was statistical significance descended than that in the NDR group ( P < 0. 05 ). Compared with the NPDR group, NDR group and control group, the RNFL thickness of optical disc in each quadrant were descended significantly. There was statistically significant difference in macular retinal thickness among the NDR group, mild NPDR and moderate NPDR group ( P<0. 05), the retinal thickness was increased gradually in mild NPDR and moderate NPDR group.
CONCLUSION:With the development in the degree of early DR, RNFL thickness is gradually decreased and retinal thickness is increased, OCT can be observed qualitatively and quantitatively in DR.

?AIM:To improve the efficiency and quality of teaching, and to cultivate students’ ability to analyze and solve clinical problems, the case - based learning ( CBL ) combined with problem-based learning ( PBL ) teaching mode is introduced into the clinical teaching of ophthalmology.?METHODS:Two classes ( total 131 students ) of 2013 grade major in clinical medicine, Kunming Medical University, were randomly selected as experimental group using CBL combined with PBL teaching mode, and control group using traditional teaching mode. The part of acute angle-closure glaucoma was taught. The scores of the experimental group were compared with that of control group at the end of term.?RESULTS:The mean scores of CBL combined with PBL teaching group were significantly higher than that of traditional teaching group.?CONCLUSION: The application of CBL combined with PBL in the clinical teaching of ophthalmology has obvious advantages in improving the learning interests and promoting students’ self-learning ability. It is helpful in improving the students’ ability of independent-thinking, analyzing and solving problem.
