Objective To investigate the emergency treatment and correlation factors of aqueous misdirection during glaucoma and cataract surgery in glaucoma patients.Design Retrospective case series.Participants 126 cases(132 eyes)of angle-closure glaucoma patients with aqueous misdirection during surgery,100 cases(100 eyes)of angle-closure glaucoma patients without aqueous misdirection during surgery and 100 cases(100 eyes)of senile cataract patients.Methods We performed pars plana vitreous water-bag aspiration or anterior vitrectomy on glaucoma patients with aqueous misdirection during surgery.All the factors in observation group and control groups were compared and analyzed by logistic regression.Main Outcome Measures Preoperative highest intraocular pressure(HIOP),intraocular pressure after maximum dose(IOP),anterior chamber depth(ACD),lens thickness(LENS),axial length (AXL),mean keratometry(K),intraocular lens diopter within-0.5D corrected by SRK-T formula(IOLD).Results Among all the 132 angle-closure glaucoma eyes whose posterior chamber pressures were increased during surgery,we performed pars plana vitreous water-bag aspiration in 123 eyes(93.18%),and anterior vitrectomy in 9 eyes(6.8%).Postoperative complications included shallow anterior chamber in 20 eyes(7 eyes with malignant glaucoma,9 eyes with choroidal detachment,4 eyes with delayed local suprachorodal hemorrhage),and vitreous local hemorrhage in 1 eye.Means of all the observation indexes on three groups showed significant difference(all P

Osteoblasts are the most important mechanoreceptive and osteogenic cells.The loss of bone in microgravity is mainly due to the dysfunction of osteoblasts.Research on osteoblast cytology under simulated weightlessness has made great progress in recent years.Current experiments are focusing on the changes in the cellular proliferation,differentiation,apoptosis, function and signal transduction in osteoblasts.This paper reviews the progress of the studies in this field.

Objective To detect the relationship between CAG repeat in IT15 gene and clinical manifestations of Huntington's disease (HD).Methods Non-denaturing polyacrylamide gel electro- phoresis method was used to detect CAG repeat.Clinical manifestations were scored by UHDRS and MMSE. Results Genotypes of IT15 were heterozygous in all 29 HD patients.CAG repeat in the HD chromosome, being 42—62,13—28 in normal chromosome,was inversely correlated with age of onset (r=-0.539,P

Objective:To explore the cooradinative training model of postgraduate and and residency of nuclear medicine based on the ability promotion. Develop the learning of basic medical imaging knowledge, the training of clinical practice, the development of scientific research ability and the training of new technology and so on.Methods: Bibliometric analysis was used to analysis the domestic and overseas current situation and research hotspot about carrying out the training of clinical medicine and residency. Combing the existing problem and combined the characteristic of medical imaging, a training model based on ability enhancements be proposed and supporting system is constructed.Results:Search on the Wanfang Database, 170 literatures were obtained from 2007 to 2016 about training of postgraduates and residents of clinical medicine. The annual distribution was increased gradually, the articles number in 2016 was 4.3 times than in 2007. The research hotspots focus on the integration of medical postgraduate student and resident, clinical ability and cultivation of scientific research thinking ability , the penetration of new technology and the choices of research topics. Literature review shows the postgraduates of medical imaging faced the deficiency of anatomy and radiology knowledge, the capacity for scientific research, the training of new radiology technology. Proposed nuclear medicine postgraduate students and residency training cooradinative transformation of the new model and developed a corresponding training curriculum training system.Conclusion: Based on the background of capacity enhancement, the new model of postgraduate and clinicians training mechanism, the operation of collaborative transformation model, reasonable arrangements for the training and scientific research, the focused training, these methods could effectively satisfied both training needs. In order to develop the high-quality talent with both clinical experience and scientific research ability.

Objective To evaluate the efficacy of entecavir treatment on hepatitis B patients with acute-on-chronic liver failure. Methods Eighty-four hepatitis B patients with acute-on-chronic liver failure were treated with entecavir 0.5 mg daily and Other routine drugs. Another 99 hepatitis B patients with acute-on-chronic liver failure were treated with only routine drugs as control. The survival, liver functions, hepatitis B virus (HBV) DNA level, prothrombin time (PT) were observed. The survival rates of patients with early, middle or late stage of liver failure were analyzed. The comparison of rates were done using chi-square test. The numeration data were compared by t test. The survival rates were compared using Kaplan-Meier method. Results Among patients with early stage of acute-on-chronic liver failure, the survival rate in treatment group was 63.3% (31/49), which was significantly higher than that in control group (39.7%, 23/58) (χ2=5.923, P=0.015). Among patients with middle stage of acute-on-chronic liver failure, the surviral rate in treatment group was 63.0% (17/27), which was significantly higher than that in control group (35.1%, 13/37) (χ2=4.854, P=0.028). Among patients with late stage of acute-on-chronic liver failure, four out of eight cases survived in treatment group, while one out of four cases survived in control group. In patients with serum total hilirubin (TBil) level > 342 μmol/L, the survival rate was 56.0% in treatment group, which was significantly higher than that in control group (26.8%) (χ2=9.351,P=0.002). At week 4 of the treatment, the HBV DNA reduction in treatment group was 3. 95 lg copy/mL, which was higher than that in control group (1.78 lg copy/mL) (t=5.847, P=0.001). Conclusions Entecavir treatment could improve the survival rate of hepatitis B patients with early or middle stage of acute-on-chronic liver failure. And the further study with larger population is needed in patients with late stage of liver failure. In addition, entecavir therapy could also improve the survival rate of patients with TBil >342 μmol/L.

Objective To understand the current status of hypertension in Jingzhuang Town,Yanqing District,Beijing. Method With randomized cluster sampling,3 653 residents aged over 30 yrs old were investigated by a standard questionnaire on hypertension epidemiology.Result The prevalence rate of hypertension in Jingzhuang Town was 33.3%,and increased with the age(P0.05).The main patients were those with degree 1 hypertension(62.8%).There were 37.8%of people with normal blood pressure who had high-normal values,the highest(44.3%)in 60～69 yr group.In population with hypertension,the rate of people taking medication was 24.5%,disease control rate was 8.6%,while in patients aged 30～49 yrs,these rates were 7.1%and 2.9% respectively.Conclusion The prevalence of hypertension in Beijing's suburb was serious with a younger trend.There was a large part of people with high-normal blood oressure.
