Objective To evaluate the effects and security of PFNA and DHS in the treatment of unstable intertrochanteric fractures through meta analysis .Methods The randomized controlled trials(RCT) for comparing PFNA and DHS in the treatment of unstable intertrochanteric fracture were retrieved from MEDLINE ,EMbase ,Pubmed ,Cochrane library ,CBM ,CNKI ,VIP data‐bases by computer .The related orthopedic relevant documents and conference papers were collected by manual retrieval .The Rev‐Man5 .1 statistical software was used for conducting the meta analysis .Results Nineteen RCT were included ,involving 1 690 pa‐tients ,in which 871 cases were treated by using PFNA and 819 cases were treated by using DHS .Compared with DHS ,PFNA had the advantages of little trauma ,less blood loss ,short operation time ,short fracture healing time and postoperative bed time ,good hip function and low incidence of postoperative coxa vara and screw cutting ,but there were no statistical differences in the aspects of length of hospital stay ,fatality rate ,and incidences of fracture nonunion ,breakage of internal fixation ,femoral head necrosis ,short‐ening of the femoral neck ,femoral shaft fractures ,deep vein thrombosis ,urinary tract infection and other complications between the two groups(P>0 .05) .Conclusion The retrieved literatures show that PFNA internal fixation is superior to DHS internal fixation in treatment of unstable intertrochanteric fractures .

Objective To study the effects of Batroxobin( BX) on the intimal proliferation of graft veins. Methods In this study 25 dogs were selected and evenly divided into experimental group, control group and sham operation group. In experiment and control group, a segment of auto- femoral vein were grafted into femoral artery by clean microsurgery technique. In experimental group, BX was given at the dosage of 0. 1 BU/kg, dayly?2 preoperatively, and once a day for consecutive 6 days postoperatively. Plasma NO, ET was determined in the three groups. Computer image analysis system was applied to calculate the thickness of neointima and media in the vein grafts, immunohistochemistry was used to identify PCNA and C-myc. Result The experimental group had a higher level of NO and lower level of ET compared with control group and sham operation group(P 0. 05 ). The PCNA expression in experimental group was statistically different from that of the control group(P

Twelve flavonoids were isolated from an ethanol extract of Machilus wangchiana by a combination of various chromatographic techniques including column chromatography over silica gel and Sephadex LH-20 and reversed-phase flash chromatography and HPLC. Their structures were identified by spectroscopic data analysis (IR, MS, and NMR) as (+)-catechin (1), (-)-epicatechin (2), 3'-O-methyl-(+)-catechin (3), 3'-O-methyl-(-)-epicatechin (4), 3, 5, 7, 2', 5'-pentahydroxy flavan (5), (-)-naringenin (6), (-)-eriodictyol (7), (-)-liquiritigenin (8), (2R,3R)-(+)-dihydrokaempferol (9), (2R,3S)-(-)-dihydro- kaempferol (10), (2R, 3R)-(+)-taxifolin (11), and quercetin (12). Compounds 1-10 are isolated from the genus Machilus for the first time.

Objective To investigate the immunological properties of Rv1009 domain. Methods BALB/c mice were immunized with Rv1009 domain three times at 2-week interval. ELISA was used to detect the antiRv1009 domain antibody titer in the sera of immunized mice sera. The spleen lymphocytes of the immunized mice were separated and the stimulation index (SI) was measured by MTT colorimetry. Levels of secreted IFN-γ, IL-10 and IL-12 upon specific antigen stimulation were detected by ELISA. The BALB/c mice immunized with Rv1009 domain were intravenously infected with MTB H37Rv. Four weeks after the final injection, the number of CFU in spleens was determined. Results The titer of the specific antibody in sera of the immunized BALB/c mice was 1:12 800. The SI of Rv1009 domain immunized group (2. 40±0. 18) was significantly higher than that of saline immunized group (0.90±0.21). The IFN-γ,IL-10 and IL-12 levels in culture supematant of spleen lymphecytes from the fusion proteins immunized mice was (1 432±30) ng/L, (503±11) ng/L and (311±11) ng/L respectively, significant different from that of saline immunized group[(256±20) ng/L, (76±6) ng/L and(56±8) ng/L,P<0.01]. Four weeks after the final injection,compared with normal saline immunized mice (6.64±0.13), dramatic reduction in MTB replication was observed in the spleen (4.86±0.14) from BALB/c mice immunized with fusion proteins following a subsequent MTB H37Rv challenge, but the protection efficacy of mice immunized with Rv1009 domain was not as good as that of BCG vaccination group (3.81±0.16). Conclusion Rv1009 domain can be used as a candidate for the new TB vaccine.

OBJECTIVETo observe the clinical efficacy of Shugan Yiyang Capsules in the treatment of asthenospermia and its action mechanisms.
METHODSWe randomly assigned 135 asthenospermia patients to groups A (n = 47), B (n = 45), and C (n = 43) to be treated with Shugan Yiyang Capsules, oral levocarnitine, or combination of the two. We observed sperm quality and the level of α-glucosidase in the seminal plasma before and after medication.
RESULTSThe total effectiveness rate was 70.21% in group A (markedly effective in 16 cases and effective in 17), 68.89% in group B (markedly effective in 15 cases and effective in 16), and 83.72% in group C (markedly effective in 16 cases and effective in 20), significantly higher in C than in A and B (P < 0.05). Both sperm quality and the level of α-glucosidase in the seminal plasma were improved in the three groups of patients, most obviously in group C.
CONCLUSIONShugan Yiyang Capsules can be used for the treatment of asthenospermia, and its effect can be enhanced in combination with oral levocarnitine.

Objective To evaluate ultrasound-guided methylene blue dyeing for radical liver segmental resection.Methods Liver segmental resection with uhrasound-guide methylene blue dyeing (UMD-SR) was performed in 16 cases, results were compared with 16 conventional liver segmental resection (CSR) retrospectively.Results All the operations under uhrasound-guided methylene blue dyeing were successfully carried out, among them, reverse dyeing was used in cases with segment Ⅳ, Ⅴ, Ⅷ resection.The blood loss in UMD-SR group was much less than CSR group(t =3.011 ,P =0.009) , at the cost of a longer operation time (t =5.423,P =0.000 07).There was no difference in the mortality and morbidity rates between two groups.Tumor recurrence rate was 6.25% in UMD-SR group and 18.75% in CSR group (x2 =0.133,P =0.285).Conclusions Ultrasound-guided methylene blue dyeing liver segmental resection can reduce the blood loss during operation, improve the safety of hepatectomy in case of hepatic carcinoma.

Objective To investigate the feasibility and clinical effect of cannulated screws plus separate vertical wirings technique for acute fracture of the inferior pole of the patella.Methods From May 2012 to September 2013,14 patients with fresh closed unilateral fracture of the inferior pole of the patella were treated with the cannulated screws plus separate vertical wirings.Eight patients were injured in traffic collisions and 6 in fall accidents.Fracture AO classification was type 34A1 in 8 patients and type 34A2 in 6 patients.Time from injury to operation was 1-7 days (mean,2.5 days).Number of tie wires was determined according to the degree of fracture comminution.Fracture healing,fixed position and patellar length were evaluated by radiographic examination postoperatively.Knee mobility and Bostman evaluation system were investigated to analyze the clinical effect.Results All the patients obtained average 15-month follow-up (range,12 to 29 months).At postoperative 2 months,the fracture healed with good alignment of the broken bone and proper place of the internal fixation device noted on the X-ray films.At postoperative 6 and 12 months,X-ray films revealed fracture bony healing,good location of the wire internal fixation,and no apparent shortening of the patella.At the 12 months,range of knee motion was (126.0 ± 4.5) ° for flexion and (2.0 ± 1.7) ° for extension.Bostman functional score for patella fracture was (28.1 ± 1.9) points.And 12 patients were rated as excellent and 2 good,with excellence rate of 100%.Conclusion Cannulated screw fixation plus separate vertical wiring is effective to stabilize patella inferior pole fracture and has good results,indicating a recommended surgical method.
