?AlM: To analyze the result of ultrasound biomicroscopy ( UBM ) of patients with rhegmatogenous retinal detachment ( RRD ) who need to perform pars plana vitrectomy ( PPV ) to explore the value of clinical application of UBM at preoperation.
?METHODS:Patients who underwent PPV for RRD in our hospital from January to December 2014 were selected. The preoperative results of UBM were recorded and the positive findings of UBM were analyzed, the value of preoperative application of UBM was investigated.
?RESULTS:Totally 356 cases (357 eyes) of patients with RRD were received PPV. All patients were examined by UBM, 122 eyes ( 34. 17%) were positive, 56 eyes were ciliochoroidal detachment, 28 eyes were narrow anterior chamber angle, 6 eyes were chamber angle-closure, 28 eyes were ciliary body cyst, 4 eyes were iris cyst, 11 eyes were anterior proliferative vitreoretinopathy, 1 eye was retinal cyst. There were 12 eyes existing two lesions at the same times. ln this study, patients with choroidal detachment was detected by UBM in 56 eyes, the positive rate was 15. 7%, while 25 eyes was detected by B -ultrasonography, the positive was 7. 0%. The difference was statistical significant(χ2=13. 382, P<0. 05).
?CONCLUSlON: The patients with RRD have underwent PPV for the condition of illness, preoperative UBM can be examined to detect the condition of anterior chamber angle, iris, ciliary and anterior choroid, which is significant for comprehensively understanding the preoperative condition of patients, estimating the difficulty of the operation, and guiding operation and the postoperative follow-up.

OBJECTIVETo investigate the mechanism of Yanshu Injection (YI) for overcoming multidrug resistance in breast carcinoma MCF-7 cells.
METHODSHuman breast carcinoma MCF-7 cells and doxorubicin-resistant MCF-7/DOX cells were treated with YI. Its inhibition on the cell proliferation was detected by MTT assay. The fluorescence intensity of doxorubicin was detected by flow cytometry. The expression of apoptosis related protein and P-glycoprotein were examined by immunoblotting after treated by YI.
RESULTSThe inhibitory action of YI on MCF-7/DOX cells was similar to that of MCF-7 cells, indicating no cross resistance (P > 0.05). 1/16 YI could obviously induce the apoptosis of MCF-7 cells and DOX cells. 1/256 YI +5 nmol/L doxorubicin and 1/128 YI +5 nmol/L doxorubicin could reduce the survival rate of MCF-7/ DOX resistant cells from 86.8% to 74.6% (P < 0.05) and 71.6% (P < 0.01) respectively, showing obvious synergistic effect. Besides, the accumulation of doxorubicin was increased after treated by YI in the MCF-7/ DOX cells. Results of immunoblotting indicated that reduction of P-glycoprotein expression was detected in MCF-7/DOX cells after exposure to YI.
CONCLUSIONYI could overcome the multidrug resistance in breast carcinoma MCF-7 cells possibly through reducing the expression of P-glycoprotein.

A brief description of performance appraisal as used in the healthcare sector, and an analysis of problems existing in performance appraisal for posts in community heahhcare organizations in the country. The paper proposes a job-analysis based performance appraisal for such posts, featuring the appraisal model of "performance + skills + attitude+ work intensity". On the basis of work analysis, a job description should be worked out for such healthcare workers as doctors, nurses and prevention workers in community healthcare organizations, aided by a targeted job-based performance appraisal system. These efforts can effectively enhance the job performance in such organizations, catering to the healthcare needs of community residents.

Objective To detect potential proteins which may play a key role in pathogenesis and early diagnosis for Acinetobacter baumannii sepsis,and compare the protein profile of neutrophils of na(i)ve rats with that of rats infected with Acinetobacter baumannii.Methods Using two-dimensional electrophoresis for separation of proteins,we compared the differences of the profile of total proteins from neutrophils of na(i)ve rats with that of rats infected with Acinetobacter baumannii.Differences in the profiles of expressed proteins were observed,and some of the proteins were isolated and verified by line mass spectrometry analysis and Western blot.Results Fifty proteins from the neutrophils of rats with Acinetobacter baumannii sepsis were found to be different from those of naive rats.Forty-one of these proteins were able to be identified successfully using two-dimensional electrophoresis,in which 24 were upregulated,and 17 were downregulated compared with the proteins isolated from neutrophils of na(i)ve rats.Conclusion The protein profile of neutrophils in rats with Acinetobacter baumannii sepsis is significantly different from that of na(i)ve rats.These proteins can be identified by proteomic screening,and may be used as potential markers for early diagnosis and molecular targets for effective treatment of Acinetobacter baumannii sepsis.

Objective To investigate the infection of Xuebijing injection on inflammatory factor of large sized avulsion patients.Methods 70 patients being selected with large sized avulsion were randomly recruited into a treatment group(35 patients)and a control group(35 patients).The control group received traditional comprehensive treatment.On this basis,Xucbijing injection was injected to the treatment group on admission day,and Xuebijing injection 50 ml in 0.9%NaCl solution 100 ml was,intravenously infused for 60 min once,2 times daily,up to 7 d.TNF-α,IL-6,CRP,WBC and NEU%of the two groups were respectively detected before treatment and 7 days after the treatment.Exudation of wound surface was also observed.Results After 7 days of treatment,there was significant difierence in the treatment group compared with pretreatment(P<0.01).There was statistical difference between two groups after 7 days of treatment(P<0.01).Exudation of wound surface of the treatment group was less than the control group's.Conclusion Xuebijing injection has antagonistic effect on inflammatory factor of large sized avulsion patients and can lessen exudation of wound surface.

A new and effective method to produce transgenic animals was established. Without a surgical incision, the recombinant plasmid containing green fluorescence protein (GFP) cDNA was repeatedly injected into male mouse testis at multi-sites. After few weeks of the final injection, the injected male was mated with normal oestrus female to produce transgenic mice. The presence of the GFP cDNA in F1 transgenic individuals were detected by polymerase chain reaction and Southern blot hybridization, which showed that the transgenic rate of mouse F1 offspring was 41%. The transferred gene was integrated into the host genome and could be transmitted to its offspring. When the positive F1 individuals were mated with the wild type ICR mice, the F2 individuals had a transgenic rate of 37%. The results indicate that the high efficiency of gene transfer and the limited number of manipulations make the method suitable for creating a large number of transgenic animals, especially, for producing domestic animals.

Objective:To explore the resource of rice bran by comparing antioxidative activities and growth promotion of Bacillus bifidus between supernatant of formented rice bran(RBF) by Bacillus natto and water extract of rice bran(RBW) . Method:The reducing capacity the?OH and ??O 2 scavenging capacity and the inhibitory effect to oxidize lard were determined in vitro. The growth promotion for Bacillus bifidus by photodensity with simulated condition was investigated in vivo. Results:RBF and RBW had antioxidant activity in vitro. The IC50 of scavenging?OH and ??O 250 of RBF was 3.55 mg/ml and 23.5 mg/ml,0.3 and 10 folds higher than that of RBW respectively. In inhibiting oxidation of lard,RBF had a little higher antioxidative activities than RBW,near VE. RBF and RBW could promot growth of Bacillus bifidus by 65.2% and 17.8% respectively. By enzymatic digestion,the promotive rate of RBF was still 51.6%. Conclusion:RBF had higher antioxidant activity and growth promotion to Bacillus bifidus.
