Neovascular glaucoma ( NVG ) is a kind of intractable eye disease with complex etiology, strong destruction and poor effect on treatment. Extensive retinal ischemia and hypoxia is the main etiology, and the key of treatment is early diagnosis, active prevention and taking effective measures to prevent the production of vascular endothelial growth factor. According to the related literature over recent years, the authors will discuss pros and cons for medical, surgical and combined treatment in this review.

Purpose:To investigate the relationship between HELICOBACTER PYLORI (Hp) and gastric carcinoma, as well as the possible carcinogenic mechanism by Hp. Methods: DNEL technique and immunohistochemical staining were used in the research to study the state of apoptosis, proliferation and p53 gene expression. Total 100 gastric mucosal biopsy specimens, including normal mucosa, Hp negative and Hp positive gastric precancerous lesions as well as gastric carcinomas were studied. Results:There were several apoptotic cells in the superficial epithelium and a few proliferative cells within neck of gastric glands, and no p53 protein expression in normal mucosa. In gastric carcinoma, apoptotic cells accounted for 1.62%, while proliferative cells 4.99%, and P53 protein significantly increased. in metaplasia, the apoptotic index (AI), proliferative index (PI) and positivity of p53 expression in Hp positive group were higher than those in normal mucosa ( P

Objective To observe the changes of arm equilibrium pressure (Parm) in different occlusion time,the reference range of Parm in hemodynamic stable patients,and to explore the relationship between Parm and systemic hemodynamic parameters.Methods Mechanically ventilated postoperative abdominal surgery patients who admitted to ICU with stable hemodynamic status were enrolled.After hemodynamic data were recorded,arm stop-flow maneuvers were performed to measure Parm.At 10,20,30,40,50,60 seconds after occlusion,arterial pressure were measured twice within 5 minutes and recorded as the average value.Results Thirty patients were included.The Parm decreased gradually with the prolongation of the occlusion time.The value was not stable within 60 s,but the reducing extent was not obvious after 40s.The 95％ reference range of Parm 30 S was 23-44 mmHg(1 mmHg =0.133 kPa) and Parm 60 S was 19--35 mmHg.Parm at 30 s and 60 s were positively correlated with systolic arterial pressure,diastolic arterial pressure,mean arterial pressure,central venous pressure (all P ＜ 0.001),but not heart rate and pulse pressure.Linear regression analysis showed that Parm at 10 s,20 s,30 s only had linear correlation with diastolic arterial pressure (10 s,β =0.504,P =0.001;20 s,β =0.297,P =0.005;30 s,β =0.231,P =0.015),and Parm at 40 s,50 s,60 s were linear correlation with diastolic arterial pressure (40 s,β =0.220,P =0.004;50 s,β =0.210,P =0.004;60 s,β =0.213,P =0.004) and central venous pressure (40 s,β =0.516,P =0.018;50 s,β =0.513,P =0.01;60 s,β =0.472,P =0.023).Conclusion In mechanically ventilated postoperative abdominal surgery patients with stable hemodynamic status,Parm decreases when occlusion time is prolonged,which is not stable within 60 s occlusion.Arterial blood pressure and central venous pressure are positively correlated with Parm.

Objective The aim of this study was to assess the current situation and master degree on medical statistics among the medical correlation personnel, in order to provide useful information for transformation of education towards the medical correlation personnel . Methods Using cluster random sampling method to select 358 the medical correlation personnel who were recruited from health institutions in Chongqing to respond to the questionnaires. Questionnaire including respondent basic information, statis-tical knowledge and statistical knowledge needs. The data of the survey were analyzed by chi-square test, descriptive statistics analysis. Results 94.7% of the surveyed used statistical knowledge in the process of work or study. The main concentration of medical statistical knowledge utilization rate, the proportion of receive professional education or training courses of medical statistics and the willingness to participate in specialized training of medical statistics is 20-30 age group, No Title group, Master and over group andStudents group. As for ten categories of common statistical methods, thirty percent of people can use them skillfully, but the majority of the more advanced statistical analysis methods cannot be used or have never heard of. The greatest demand for learning ten kinds of common statistical methods is calculating cor-rectly through statistical software. Conclusion The vast majority of medical personnel need to use medical statistics in the actual work and study, but they have a lower mastery of statistical methods. Therefore, we should strengthen the medical statistics teaching and training for medical personnel.

OBJECTIVETo observe the therapeutic effect and relevant mechanism of shuxuening Injection (SI) in treating patients with active ulcerative colitis (UC).

METHODSTotally 91 patients with active UC were randomly assigned to 2 groups, 44 in the control group and 47 in the treatment group. Patients in the control group received routine treatment, while patients in the treatment group additionally received intravenous injection of SI (15 mL), twice daily for 14 days in total. Colonoscopy was performed before and after treatment. The therapeutic effect was assessed by Mayo scoring system and the grading of activities evaluated by Baron endoscope. Serum levels of IL-6 and TNF-α were detected by ELISA. The activity of SOD was detected by xanthine oxidase method. The content of MDA was detected by thiobarbituricacid (TBA). Besides, 20 healthy subjects were recruited as the healthy control group.

RESULTSTotally 82 patients completed the study (40 in the control group and 42 in the treatment group). There was no statistical difference in serum levels of IL-6, TNF-α, SOD, MDA, the Mayo score and endoscope grading between the two groups before treatment (P >0. 05). Compared with the healthy control group, serum levels of IL-6, TNF-α, MDA significantly increased (P <0.01), and the serum SOD level decreased (P < 0. 05) in the treatment grup and the control group before treatment. Compared with before treatment in the same group, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased in the treatment group and the control group after treatment (P <0. 01, P <0. 05). Compared with the control group after treatment, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased (P <0.01, P <0.05), the serum SOD level increased (P <0.05) in the treatment group after treatment. The serum SOD level was obviously negative correlated with serum levels of IL-6, TNF-a, Mayo score, and endoscope score (r = -0. 621, -0.638, -0. 509, -0.787, P <0.01). The serum MDA level was obviously positive correlated with serum levels of IL-6, TNF-α, Mayo score, and endoscope score (r =0.711, 0. 882, 0. 525, 0. 639, P <0.01).

CONCLUSIONSI could improve inflammatory injury and clinical symptoms of patients with active UC, and its mechanism might be associated with antioxidant and scavenging oxygen free radicals.

OBJECTIVETo observe changes of gonad functions of Gan-qi stagnation (GS), Pi deficiency (PD), Gan-qi stagnation Pi deficiency (GSPD) model rats, and the effect of Chaishu Sijun Decoction (CSD) on them.

METHODSRats were randomly divided into 7 groups according to romdom digit table, i.e., the normal control group, the GS model group, the GS medication group, the PD model group, the PD medication group, the GSPD model group,and the GSPD medication group, 10 in each group. Rats in the GS model group, the PD model group, and the GSPD model group were treated with chronic restraint, improper diet +excessive fatigue, chronic restraint +improper diet +excessive fatigue. The model was established for 4 successive weeks. Starting from the 15th day of modeling, CSD at the daily dose of 3.57 g/kg was given by gastrogavage to them for 14 successive days. Equal volume of distilled water was given by gastrogavage to rats in each model group and the normal control group for 14 successive days. The blood contents of gonadotrophin releasing hormone (GnRH), follicular stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and testosterone (T) were detected in rats of each group.

RESULTSCompared with the normal control group, there was statistical difference in GnRH, T, E,, and FSH in the GS, PD, and GSPD model groups (P < 0.05, P < 0.01). The content of LH was elevated in the GS model group (P < 0.05) and declined in the GSPD model group (P < 0.01). Compared with the GS model group, the contents of FSH, LH, and T decreased and E2 increased in the PD model group (all P < 0.05); the contents of FSH and LH also declined in the GSPD model group (P < 0.05). Compared with the PD model group, the T content increased and FSH decreased in the GSPD model group (all P < 0.05). Compared with each corresponding model group, the FSH content decreased (P < 0.01) and LH increased in the GS medication group; the T content increased, E2 and LH decreased (P < 0.05, P < 0.01) in the PD medication group; the T content decreased (P < 0.01), GnRH, E2, FSH, and LH increased (P < 0. 05, P < 0.01) in the GSPD medication group.

CONCLUSIONSThere exist different degrees of abnormal function of the gonad axis in the GS, PD, and GSPD models. CSD had certain regulatory effect on the 3 syndromes. Of them, it showed a more comprehensive role in improving the gonad function axis. Results of this experiment had provided the experimental evidence for higher correlation between CSD and GSPD syndrome.
