OBJECTIVE:To systematically review the efficacy and safety of pituitrin combined with phentolamine versus pitui-trin alone in the treatment of bronchiectasis hemoptysis(BH),and provide evidence-based reference for the clinical treatment. METHODS:Retrieved from PubMed,Cochrane Library,EMBase,CJFD,Wanfang and VIP database,the randomized controlled trails(RCT)about pituitrin combined with phentolamine(test group)versus pituitrin alone(control group)in the treatment of BH were collected,and afterdata extract and quality evaluation ,Meta-analysis was performed by using Rev Man 5.2.3 statistics soft-ware. RESULTS:A total of 43 RCTs were included,involving 3 094 patients. Results of Meta-analysis showed the significant effi-cacy [RR=1.50,95%CI(1.38,1.62),P<0.001] and effective rate [RR=1.25,95%CI(1.20,1.30),P<0.001] in test group were sig-nificantly higher than control group,inefficacy [RR=0.29,95%CI(0.23,0.36),P<0.001], hemoptysis stopped or remission time [MD=-2.00,95%CI(-2.43,-1.57),P<0.001],incidence of headache [RR=0.36,95%CI(0.22,0.59),P<0.001],incidence of chest tightness [RR=0.41,95%CI(0.26,0.63),P<0.001],incidence of abdominal pain [RR=0.26,95%CI(0.16,0.43),P<0.001] and incidence of elevated blood pressure [RR=0.28,95%CI(0.14,0.56),P<0.001] in test group were significantly lower than control group,there were significant differences in 2 groups. CONCLUSIONS:Pituitrin combined with phentolamine has better efficacy and safety than pituitrin alone in the treatment of BH. Due to the limit of methodological quality and sample size,it re-mains to be further verified with more rigorously designed and long-term follow-up of large-scale RCT.

OBJECTIVE To determine the distribution of bacterial flora in hospital infection and to provide laboratory(evidence) for controlling hospital infection and selecting rationally antibiotics in clinic practice.METHODS All(isolates) were identified by routine procedure.MRSA and ESBLs-producing rate of Escherichia coli and Klebsiella pneumoniae were(examined.) RESULTS Among all these clinical infectious specimens,there were 202 strains of Gram negative bacilli,(accounting) for 40.9%(202/495);166 strains of fungi,accounting for 33.5%;621 strains of Gram positive cocci,for 20.6%(102/495).Candida albicans,E.coli,Pseudomonas aerugionosa,C.tropicalis and C.glabrata took the first five bacteria in infection.Analysis of drug resistant bacteria suggested that the isolated rate of ESBLs-producing strains in Staphylococcus aureus be 47.6%,be CNS in MRCNS 78.1% and MRSA in SA be 42.3%.CONCLUSIONS Multidrug resistance and fungus infection are the main risk factors in our hospital.We must improve means of treatment on clinical work and use antibiotic rationally to reduce the infection rate.

Objective To observe inhibiting effect of endostatin on subcutaneous transplant tumor of breast carcinoma, and to illuminate the therapeutic effect of endostatin in the cancer. Methods The effect of en-dostatin on MCF-7 cell proliferation was studied by MTr. The model of MCF-7 cell transplant tumor on nude mice was constructed. Endostatin was injected intradermally around the transplant tumor. Inhibition effect on the tumor was observed. Results Endostatin with the concentration of 10 μ/mL and 15 μg/mL can inhibitMCF-7 cell proliferation effectively (P < 0. 05 ). After endostatin injection, tumor weight, volume and mi-crovessel density decreased significantly(P < 0.05 ). Conclusion Endostatin can inhibit breast carcinoma proliferation through inhibiting angiogenesis and the tumor cell itself.

Objective To investigate the efficacy of bend-assisted laparoseopie fight bemicolectomy for right colon carcinoma in elderly obesity patients. Methods 20 obesity eases undergoing hand-assisted laparoscopic right bemicolectomy were retrospectively reviewed, and compared with 25 obesity cases with transabdominal right hemicolectomy in the same period. The safety, recovery, eradication and stress reaction were compared. Results In hand-assisted laparoscopic group, there were less bleeding loss, rapid recovery to normal temperature and gastrointestinal function,ont of bed activity, short-time hospitalization compared with transabdominal group(P <0.01). There were no differences in operative time, numbers of lymph nodes removed, postoperative complications and length of specimen between two gronps(P > 0.05). CRP, IL-6, adrenocorticotrophic hormone (ACTH) and cortisol were more significantly increased in two groups after operation than before operation (P < 0. 05) , and this increase was moreprominent in transabdominal group than in hand-assisted laparoacopic group (P < 0.05). Conclusion Hand-assis-ted laparoscopic right hemicolectomy is a safe and effective way for elderly obesity patients,especially in postoperative recovery and physical stress reaction.

AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis.
METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared.
RESULTS:(1) The clinically total effective rate was 74%of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups ( P<0. 05 ); ( 2 ) the satisfaction scores were (3. 89±1. 22) points and (6. 27±1-86) points of the the control group before and after treatment, which were ( 4. 00±1. 34 ) points and ( 8-95±2-34) points of the observation group, and there were statistical differences of the two groups before and after treatment (P<0. 05), and the scores of the observation group were higher than that of the control group ( P<0-05);(3) complications such as swelling and stitches off appeared in both groups, and the rate was 21% in the control group, which was 11% in the observation group, and there were statistical differences between the two groups (P<0. 05).
CONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation;partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

Objective:To investigate the effectiveness and safety of manual acupuncture for memory loss and sleep quality in chronic insomniacs.Methods:A total of 60 eligible participants were enrolled and randomized into either a treatment group or a control group,with 30 cases in each group.The treatment group was intervened by manual acupuncture whereas the control group was given sham acupuncture.In the two groups,the interventions were offered once every other day and three times a week,for 8 weeks in total.Before and after the treatment,Pittsburgh sleep quality index (PSQI) and eventrelated potentials (ERPs) were used to assess the patients' sleep quality and memory,respectively.Meanwhile,adverse events were monitored and recorded.Results:After 8-week treatment,both the treatment group and the control group showed a significant decrease in the PSQI global score (P＜0.001,P＜0.01),and the decrease in the treatment group was more significant than that in the control group (P＜0.001).The intra-group comparisons of ERPs indicated that,the latencies of N1 and P3 were shortened and the amplitudes of N1 and P3 were increased in the treatment group after the intervention,and the differences were statistically significant (P＜0.05,P＜0.001);in the control group,there were no significant changes in the latency and amplitude after the treatment (P＞0.05).The between-group comparisons of ERPs showed that the treatment group was more effective than the control group in shortening the latency of P3 (P＜0.01).Conclusion:Acupuncture can be a safe and effective treatment option for chronic insomnia coupled with memory impairment.

OBJECTIVETo explore the correlation of the gene polymorphisms of Toll-like receptor 2 ( TLR2) and TLR4 with the susceptibility and recurrence of condyloma acuminatum (CA).

METHODSUsing Snapshot, we detected the gene polymorphisms of TLR2 597(T/C), 1350(T/C), 15607(A/G), and 2258(G/A) and TLR4 896(A/G) and 1196(C/T) in the peripheral blood of 140 CA patients and 105 HPV-negative controls. We made comparisons between the CA patients and controls as well as between the cases of recurrent CA and those of non-recurrence at 6 months after treatment.

RESULTSThere were 72, 48, and 20 cases of genotype TT, TC, and CC of TLR2 597 (T/C), respectively, in the CA patients, as compared with 71, 31, and 3 cases in the controls. The gene frequency of mutant C was 31. 43% in the patients, significantly higher than 17.62% in the controls (χ2 = 12.04, P < 0.01), and it was 38.68% in the recurrent cases, remarkably higher than 27.01% in the non-recurrent cases (χ2 = 4.16, P < 0.05). There were 74, 49, and 17 cases of genotype TT, TC, and CC of TLR2 1350( T/C), respectively, in the CA patients, as compared with 73, 29, and 3 cases in the controls. The gene frequency of mutant C was 29. 64% in the patients, significantly higher than 16. 67% in the controls (χ2 =11.05, P < 0.01), and it was 36.79% in the recurrent cases, markedly higher than 25. 29% in the non-recurrent cases (χ2 = 4.18, P < 0.05). There were 44, 66, and 30 cases of genotype AA, AG, and GG of TLR2 15607(A/G), respectively, in the CA patients, as compared with 26, 58, and 21 cases in the controls. There was no significant difference in the gene frequencies of mutant G between the two groups (χ2 = 0.33, P > 0.05). No mutant genes of TLR2 2508 (G/A) or TLR4 896(A/G) and 1196(C/ T) were detected in either the CA patients or the controls. Linkage disequilibrium analysis showed a tight linkage between TLR2 597 (T/C) and 1350(T/C) (D' = 1, r2 = 0.93).

CONCLUSIONTLR2 597(T/C) is tightly linked to 1350(T/C), which is correlated with both the susceptibility and the recurrence of condyloma acuminatum.

Combining the structural features of picotamide and linotroban, a series of N,N'-bis-(halogenophenyl)-4-methoxybenzene-1, 3-disulfonamides were designed and synthesized on the basic principles of drug design. The structures of target compounds were confirmed by IR, 1H NMR and HR-MS, and the in vitro antiplatelet aggregation activity was evaluated by Born turbidimetric method with adenosine diphosphate (ADP) as the platelet aggregation inducers. The assay results showed that twelve compounds (4b, 4f, 4l, 5b, 5d-5g, 5j, 5k, 5m and 5n) were found to have superior anti-platelet aggregation activities than the positive drug picotamide. The preliminary structure-activity relationship (SAR) has been explored.
