?AlM:To evaluate and observe the efficacy of silicon oil ( SO ) , perfluoropropane ( C3 F8 ) and balanced salt solution ( BSS ) that can be used as tamponade during vitrectomy to treat proliferative diabetic retinopathy ( PDR) complicated with vitreous hemorrhage ( VH) .
?METHODS: Studied retrospectively on 74 eyes of 60 patients who underwent vitrectomy surgery with diabetic vitreous hemorrhage in our hospital during June 2008 and June 2014. Based on repeated prior examines on fundus details and the vitrectomy tamponades were chosen. All the patients had been followed up at least 3mo. Depending on different tamponades, the paitents were nonrandomized in three groups and contrasted as visual acuity, intraocular pressure ( lOP ) and complications respectively.
?RESULTS: There was statistically significant difference among these three groups in preoperative eyesight ( P<0. 05 ). Moreover, the preoperative eyesight was statistically different between SO and BSS (P<0. 05), and difference for the rest being not remarkable(P>0. 05). The difference being statistically difference in the postoperative vision among these three groups ( P <0. 05). The further analysis showed that the paired-comparisons were statistically significant difference between SO and BSS ( P<0. 05 ), while the rest two groups of comparison were non-respectively(P>0. 05). The preoperative visual function was in contrast to the postoperative (P<0. 05). The lOP before surgery was not statistically significant difference(P>0. 05). However,the difference among three groups being statistically in the postoperative vision(P<0. 05), in addition,the difference existed in each group through pairwise comparison ( P<0. 05) . The occurence rate of complications after surgery in this survey was 47%, the SO group was 50%, the C3 F8 was 56%, the BSS group was 44%.
? CONCLUSlON: Vitrectomy is a safe and effective treatment that can help patients who have diabetic vitreous hemorrhage obtain better visual improvement. Because of the physicochemical properties and different conditions, there still has complications after surgery.

Objective To investigate psychosocial factors for post-stroke depression (PSD). Methods 405 in-pa-tients with stroke were first screened for depression using Comprehensive International Diagnostic Interview-3.0. 22 pa-tients with depression were recruited as the depression group. From 383 patients without depression, 44 patients were se-lected and served as the non depression controlled group according to the sex and age paired with 1:2. Both groups were measured by using questionnaires including Life Event Scale, Simplified Coping Style Questionnaire, Social Support Rat-ing Scale, Activities of Daily Living Scale and Quality of Life Enjoyment and Satisfaction Questionnaire, Short Form. Re-sults The score of passive coping was significantly higher in depression group than in non depression group [(1.2 ± 0.5) vs. (0.8±0.7), P<0.05]. The score of subjective support was significantly lower in depression group than in non depression group [(17.5±4.0) vs. (20.7±4.6), P<0.05]. Logistic regression analysis showed, minority nationality (OR=2.564, 95%CI:1.039~6.327) and passive coping style (OR=2.223, 95%CI:1.052~5.192) were risk factors for PSD, while subjective sup-port was protective factor for PSD (OR=0.884, 95%CI:0.793~0.986). Conclusions Passive coping style and low subjec-tive support may be the important psychosocial factors of PSD.

Objective:To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus- associated glomerulonephritis(HBV-GN).Methods:Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study.Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling(TUNEL)and the apoptotic index was calculated;immunohistochemistry was used to detect the protein expression of Bax and Bcl-2.ResuLts:The apoptotic index in HBV-GN group was obviously higher than that of the control group;the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells,seldom seen in the glomerular cells.The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells(positive in the plasma,membrane and nuclear);the expression of Bax was found in both glomerular cells and renal tubular cells,mainly in tubular epithelial cells,seldom seen in Bowman's capsule or glomerular mesangial region.Conclusion:Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells;expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells,suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.

The HPLC method was established to simultaneously determine the contents of myricetin, luteolin, apigenin and kaempferol in Wikstroemia indica ( L. ) C. A. Mey. The method was carried out on a Diamonsil C18 column (4. 6 mm x 250 mm, 5 µm) eluted with the mobile phases of water containing 0.15% phosphoric acid and acetonitrile in gradient mode. The UV detection wavelength was 365 nm. The flow rate was 1.0 mL · min(-1) and the column temperature was set at 30 °C. All the standard compounds showed a good linearity in the range of 0.100 8-1.008 (r = 0.999 2), 0.484 8-4.848 (r = 0.999 0) , 1. 354-13. 54 (r = 0.999 6), 0.316 8-3.168 mg · L(-1) (r = 0.999 0) for myricetin, luteolin, apigenin and kaempferol, respectively. The average recoveries of these four flavonoids were 98.5%, 100.9%, 99.7% and 98.9% with RSD 1.2%, 1.7%, 0.81% and 1.6%, respectively. In conclusion, the method is simple, rapid and accurate. It can be applied for the quality control of Wikstroemia indica.

Comparison of the institutional setup, policies and adverse event report mechanism for medical risk control in the countries of UK, USA, Canada, and Australia by means of browsing information on their official websites. It is found that these countries maintain a national patient safety authority, coupled with a tiered management at national, local, medical institutions and NGOs level; the USA pattern features laws and regulations, that of UK and Australia features guidelines as policy guarantee for medical safety; these countries regulate adverse event reporting by either government leadership or cooperation with trade associations. Inspirations from this study suggest China to enhance institutional construction, complete regulations, and advocate the culture for medical safety, and to build the national-level reporting and study system for medical safety events, and improve medical risk management.

The applicator therapy is a unique method to treat infant diarrhea in traditional Chinese medicines and widely applied in clinical practice. Currently, many researchers have proved the rationality of the therapy based on the traditional Chinese medicine mechanism and on the data from clinical practice, but its action mechanism is uncertain at present. In this study, with the assistance of pediatric practitioners, the automated ribosomal intergenic-spacer analysis (ARISA) was adopted to study the effect of the adjuvant therapy with Dingguier umbilical paste on intestinal flora of diarrhea infants, in which Dingguier umbilical paste served as the adjuvant therapy in oral traditional Chinese medicines and fecal samples of infants with different diarrhea symptoms were collected and used as the study materials. The results showed that the adjuvant therapy had a significant effect on the shift of intestinal flora, which was associated with the decrease in the similarity difference to the normal control group and the increase in the number of operational taxonomic units (OTUs) shared with the normal control group. Additionally, adjuvant therapy with Dingguier umbilical paste also showed long action duration and increased OTUs number. These results indicated that Dingguier umbilical paste has the effect in restoring the micro-ecosystem of unbalanced intestinal bacteria. Intestinal flora may be one of major targets for the applicator therapy for the infant diarrhea, but not for the single oral traditional Chinese medicine for infant diarrhea.
