To investigate risk factors and efficacy of reoperation for neovascular glaucoma ( NVG) secondary to vitrectomy in proliferative diabetic retinopathy (PDR).
●METHODS:Seven cases (7 eyes) from October, 2009 to December, 2012 were analyzed retrospectively. All the patients had NVG after the primary vitrectomy for PDR and were performed secondary vitrectomy combined with laser photocoagulation .
●RESULTS: The mean intraocular pressure ( lOP) was (11. 21±4. 22)mmHg before primary surgery. The number of laser spots ranged from 622 to 1124 during the first vitrectomy. Cataract extraction was performed in all 7 cases and intraocular lens was implanted in 5 cases. The mean lOP was (10. 11± 3. 62) mmHg during 2mo after the primary surgery. During follow- up, all the patients had significantly progressive intraocular inflammation. Vitreous hemorrhage was not absorbed completely in 2 cases and recurrent vitreous hemorrhage occurred in the other 5 cases. Five cases had poor glycemic control and the other 2 cases had bad blood pressure control. NVG occurred in all 7cases. The mean lOP was (41. 13 ± 7. 76) mmHg before the secondary surgery. After the secondary surgery, the lOP were under control in 5 cases. For the other 2 cases, the lOP was controlled in one case by transscleral cyclophotocoagulation, another one was lost in follow-up with uncontrolled lOP.
●CONCLUSlON: Primary vitrectomy combined with lens extraction, insufficient laser speckle, unabsorbed and recurrent vitreous hemorrhage, intraocular inflammation and systemic condition may be the risk factors associated with the occurrent of NVG after vitrectomy in PDR. Secondary vitrectomy combined with sufficient retinal photocoagulation is efficiency for NVG after vitrectomy for the PDR.

Objective To investigate clinical feature, diagnosis and treatment of tuberculosis infection in renal transplant patients. Methods To analyze clinical data of 13 patients suffering from tuberculosis infection after renal transplantation retrospectively. Results Twelve patients got lung tuberculosis while only one lymphoid tuberculosis. They were unequivocally diagnosed as tuberculosis by radiological plain film, searching acid-fast bacilli in sputum repeatedly, detecting DNA of Bacillus tuberculosis by PCR and biopsy, 4 of whom had mixed infection in lung. Eleven patients recovered after standard antituberculosis therapy, but 2 died. Hepatic function lesion was main adverse reaction in treatment, but it could get normal after adjustment of immunodepressant. Conclusion Tuberculosis incidence rate in renal transplant patients increased obviously. Standard antituberculosis therapy is effective, but immunodepressant should be adjusted in time according to the change of hepatic function and renal function.

Objective To establish mouse allergic asthma model and observe the effect of bacterial lysates (OM-85BV) on airway inlfammation. Methods Forty-eight 4 to 6 weeks healthy male BALB/c mice were used as research subjects and randomly divided into six groups, a:control group;b:OM-85BV contral group;c:allergic asthma model;d:dexamethasone group (Dex group);e:OM-85BV A group;f:OM-85BV B group (the intervention time was prolonged 10 days than group e). BALB/c mice were sensitized and challenged with ovalbumin (OVA). Mice in groups c, d, e and f were intraperitoneally administered with antigen (OVA)-Al(OH)3 on days 1, 8 and 15, others were administered by PBS. From the 17th day to the 26th day, Mice in group f were treated with OM-85BV and others were treated with normal saline. In the next days, mice in groups c, d, e and f were intranasal given OVA for 5 consecutive days. Additionally, mice in groups b, e and f were treated with OM-85BV before challenge, while mice in the group d were administered by Dex, others were treated with normal saline at the same dose. Twenty four hours after the last intranasal administration, mice were anesthetized and dissected. Lungs were lavaged with PBS and bronchoalveolar lavage lfuid (BALF) was obtained. The total inlfammatory cells and eosinophils in BALF were counted. The total IgE levels of blood serum and IFN-γ/IL-4 levels of lavage were detected. The removed parts of lung tissue were collected for histological examination. Results Compared with groups a and b, lung tissue biopsies by HE staining from the asthma group showed obvious airway inlfammation. The situation of groups d and f was signiifcantly improved than group c, while the differences between groups e and c were not evident. Total cells and the number of eosinophils in BALF of group c (90.3±13.94×104/ml) were signiifcantly higher than that in groups a and b. Compared with the control group, levels of IL-4 in BALF (119.03±19.92 pg/ml) and IgE in serum (15.86±1.97 ng/ml) increased and levels of IFN-γin BALF (90.50±13.51 pg/ml) reduced signiifcantly. The corresponding levels of groups d, e and f were signiifcantly improved than group c (P<0.01). Conclusions Administered by OM-85BV helps regulate the balance between Th1/Th2 in asthmatic mice, reduce airway inlfammation, and prevent the occurrence and development of airway inlfammation.

Purpose To investigate renal cortical blood perfusion in patients with nephrotic syndrome (NS) by region of interest (ROI) quantification.Materials and Methods Twenty-one patients with NS treated at Wuhan Union Hospital from September 2014 to January 2015 (NS group) and twenty-nine matched healthy subjects (control group) were enrolled in our study.High frequency blood flow dynamic images of the left kidney for all the subjects were acquired by color Doppler (Philips iU22).Resistance index (RI) of interlobar artery,arcuate artery and interlobular artery were measured.Vascularization index (VI),flow index (FI),vascularization flow index (VFI) were further analyzed by ROI quantification at Q-LAB work station.Results ① The signals of renal cortical blood flow in NS patients were sparse and slim;while the signals in the control group were continuous,most of which reached the edge of renal cortical.② No statistical differences of RI values of interlobar artery and interlobular artery were found between the two groups (P＞0.05);③ The renal cortical blood perfusion in the NS patients decreased significantly compared with that in control group,and the renal cortical VI,FI and VFI values in NS group were significantly lower (P＜0.01).④ Bland-Altman analysis showed that there was good repeatability in the measurement of renal cortical VI,FI and VFI.Conclusion Color Doppler flow imaging combined with RO1 quantitative technique can assess renal cortical blood perfusion accurately,which provides diagnostic information for early detection of renal damage.

This study was aimed to investigate the mechanism of CO-releasing molecules (CORM-2) induced apoptosis and the intervention effect of Xingnaojing (XNJ) Injection in neuronal cells of rats. Optical microscope was applied to observe morphologic changes of neuronal cells. MTT assay was performed to assess the survival rates of CORM-2 on neuronal cells. Apoptosis was examined by flow cytometric analysis and the expression of relative proteins was measured by western blotting analysis. At the same time the morphologic changes, survival rates and expression of relative proteins of neuronal cells were also checked after XNJ treatment. The results showed that CORM-2 can influence survival rates in a time- and concentration-dependent manner. Survival rates decreased gradually after the cultures subjected to 24 h with 100 μmol·L-1, 200 μmol·L-1, 400 μmol·L-1 and 800 μmol·L-1 of CORM-2. It can induce neuronal apoptosis and activate Caspase-3, Caspase-9 and Cytochrome C in a concentration-dependent manner. The neuronal cells were treated with 200 μmol·L-1 of CORM-2 and then incubated with 10 mL·L-1 and 20 mL·L-1 XNJ injection for 20 h. It turned out early neuronal apoptosis decreased and the expression of Caspase-3, Caspase-9 and Cytochrome C also decreased. To sum up, CORM-2 may induce neuronal apoptosis through Caspase-dependent mitochondrial pathway, which can be intervened by XNJ Injection through inhibiting Caspase-dependent mitochondrial pathway.

40), the values of BIS, electromyogram (EMG), signal quality index (SQI), mean arterial pressure(MAP), and heart rate(HR) were recorded every minute for 5min, then additional vecuronium (0.05mg/kg) was administered, and the values of the parameters above mentioned were registered for the next 10min. Results BIS value decreased significantly 3 min after the administration of the additional vecuronium (P0.05). Conclusion A misleading BIS value may be caused by the decline of muscle relaxant during the maintenance stage of propofol/fentanyl anesthesia, which greatly influence the accuracy of BIS monitoring.

0.7?g/L (n=18) and group 2 ≤0.7?g/L (n=18). Propofol concentration, BIS, and AAI were compared between the two groups. Results The patients in group 2 had a significantly higher propofol concentration in plasma (2.70 mg/L) on awakening compared with that of the group 1 (2.08 mg/L) (P
