Objective To assess the economic efficiency of glycated haemoglobin(HbA1C)determination in screening the undiagnosed diabetes among hospitalised patients. Methods Exclusive criteria were made based on the information of the electronic patient history,including age<18 years,hospitalization for diabetes treatment, and having received a transfusion within half a year. Pathology samples from participants were collected for blood routine analysis and HbA1C screening test. Screening the undiagnosed diabetes was based on the level of HbA1C. Results In this study ,1012 patients were enrolled ,78 patients with diabetes ,and 934 patients haven′t been diagnosed before. Among the 934 patients ,HbA1C level of 51 patients was over 6.5%(48 mmol/mol). These 51 patients (5.46%) were determined to have previously unknown diabetes. The prevalence of undiagnosed diabetes was 5.46% during the study period. The cost of HbA1C test was ￥1098 per new diagnosis of diabetes. Conclusions HbA1C is a simple ,inexpensive screening test for diabetes ,which can significantly improve the diagnostic efficiency,and the early detection of diabetes can slow the progression of complication and reduce the medical care expenditures.

Objective To explore immunotherapy effective combined with active immunotherapy in different time according rats bearing-tumor after paclitaxel and carboplatin chemotherapy, and to identify the optimization time and strategy of vaccine and seek rational chemo-immunotherapy strategies in ovarian cancer treatment. Methods The dynamic immunocytes number and function in established tumor treated with paclitaxel and carboplatin chemotherapy were investigated. The changes of established tumor volume and immune function of different groups were observed according to combining different time after chemotherapy and vaccine. Results Lymphopenia was observed and the number of lymphocyte subset decreased remarkably on the 6th day, but all cells were found almost recovered on 15th day after chemotherapy. There is the process of immune-enhancing from post-chemotherapy 6 day to 10 day and reversal of immune suppression temporary. The combination post-chemotherapy 6 day with CTL caused a significantly delayed tumor growth in both tumor models and induced significant the proliferation of T lymphocyte by [H] 3 releasing. The number of CD8+T cell is the highest, but the expression of Tr cell was lowest in the group of post-chemotherapy 6 day with CTL. Furthermore, the ability of CD8+T secretion IFN-γ is the most in the post-chemotherapy 6 day with immunotherapy groups. Conclusion Combinational paclitaxel and carboplatin chemotherapy has synergistic effects with active immunotherapy boosting against tumor during window periods, where 6 days after chemotherapy with the most decreased number of lymphocytes in the animal periphery might represent the optimal checkpoint for the immune therapy against tumors. Therefore, monitoring the immune status of tumor patients might become one of the important prerequisites for the effective immune therapy when designing the comprehensive therapeutic strategies.

Objective To investigate the causations, management and prevention methods on the complications of hysteroscopic procedures. Methods Retrospective analysis of 36 cases with hysteroscopic complication, focusing on their characteristics and clinical management as well as prevention methods during the ten years from 1993 to 2004. Results Among 36 cases, 11 cases with uterine perforation and incomplete perforation, which happened during the complicated procedures, were treated by both laparoscopy and laparotomy. Five cases with heavy bleeding were encountered because of the deeply injury to the uterine wall and Foley catheter was inserted into uterine cavity and it stopped the bleeding successfully except in one case done by hysterectomy. Three cases with fluid overload syndrome were cured by using diuretic agent and saline infusion. There is no serious consequence in one case with air embolism due to prompt diagnosis and treatment. Four cases with postablation-sterilization syndrome were treated effectively by performing hysterectomy plus single or bilateral salpingectomy, dilating cervical canal as well as resecting adhesions. Twelve cases with adhesion inside uterine cavity followed hysteroscopy were also treated by dilating cervical canal, underwent adhesionlysis and hysterectomy. Conclusions The potential factors causing complications of hysteroscopy include complicated procedures inside uterine cavity, higher pressure of irrigation, deep injury of endometrium as well as incomplete removal of endometrium during hysteroscopic operations. It is the necessary measures to reduce the complications by performing laparoscopy or B ultrasound monitoring simultaneously, standardizing the procedure and strengthening postoperation management.

OBJECTIVE: To study the characters of oscillatory potentials (OPs) of electroretinogram (ERG) after methanol intoxication in rats. METHOD: The SD rat models of methanol intoxication were established and divided into control group, 3-day intoxication group, 7-day intoxication group. The changes of OPs of ERG were recorded in a dark room. RESULTS: The total amplitudes of 3-day and 7-day intoxication groups decreased approximately 50% compared with that of the control group, while the schedule delayed approximately 16% and 61%, respectively. CONCLUSION The characters of methanol intoxication in rats included delay in schedule and decline in the total amplitude of OPs.

alphaB-crystallin is the structural protein of vertebrate lens, which is widely expressed in non-lens tissue. As one of the heat shock protein family members, alphaB-crystallin possesses biological properties of molecular chaperones and anti-apoptotic effects. Multi-factor injuries, such as retinopathy, inflammation and nervous system diseases, have a closely relationship with alphaB-crystallin. This paper reviews the research progress of the expression and mechanism of alphaB-crystallin in retina and extraocular tissues and organs.

OBJECTIVE: To compare the correlation between contrast vision (LV) and sweep visual evoked potential acuity (SVEP-A) among people with emmetropia, mild myopia, and moderate myopia. METHODS: The CV and SVEP-A were tested individually in 96 eyes from healthy young volunteers, including 37 eyes of emmetropia, 27 eyes of mild myopia, and 32 eyes of moderate myopia. The statistic analysis was done by ANOVA analysis and rank sum test. RESULTS: (1) With the decrease of contrast, CV and SVEP-A decreased in every group. (2) At 100% contrast, the difference of CV between emmetropia and mild myopia had statistical significance (P<0.05). At 100%, 25% and 10% contrast, the difference of CV between emmetropia and moderate myopia had statistical significance (P<0.05). (3) In the same group, the difference of 100% and 25% contrast had statistical significance (P < 0.05). So was between 100% and 10% contrast. (4) At 100% and 10% contrast, the difference of CV and SVEP-A had statistical significance (P < 0.05). CONCLUSION The CV of myopia relates to many factors including ametropia and fundus lesions. The correction of ametropia is important to the values of CV and SVEP-A.

OBJECTIV: e To find the correlation between real best corrected visual acuity (BCVA) and testing results of microperimetry and visual evoked potential (VEP) and to explore a new method in recording BCVA in macular disease. METHODS: Sixty-two patients with macular disease (macular disease group, 62 eyes) and eighteen healthy volunteers (control group, 36 eyes) had BCVA, microperimetry and VEP recorded. RESULTS: (1) By microperimetry, the values of retinal mean sensitivity and fixation percentage in macular disease group were lower than that in control group. The bicurve ellipse area in macular disease group was higher than that in control group. By VEP, P100 amplitude under 0.5 cpd and 2 cpd in macular disease group were significantly higher than that in control group and the latency was prolonged (P < 0.05). (2) In macular disease group, BCVA had significant positive correlation with retinal mean sensitivity, bicurve ellipse area, macular central 2 degrees and 4 degrees fixation percentage, respectively (P < 0.05). There was a significant correlation between retinal mean sensitivity and P100 amplitude (P < 0.05). (3) Multiple linear regression equation was y = 0.053 x1+0.008 x3+3.897 (y was BCVA, while x1 was retinal mean sensitivity and x3 was P100 amplitude under 2 cpd). CONCLUSION Combined use of microperimetry and VEP is useful in the assessment of BCVA in macular disease.
