Objective To evaluate the efficacy and safety of ustekinumab in the therapy of plaque psoriasis.
Methods Literatures published up to November 2013 were collected from Cochrane library, MEDLINE, and PubMed which were related with ustekinumab for plaque psoriasis. The efficacy was estimated using relative risk of Psoriasis Area and Severity Index (PASI) 75 response rate at the week 12 endpoint in clinical trials, and adverse effects were also analyzed. Meta-analysis was carried out by using Review Manager 5.1.
Results Six randomized control trials consistent with the inclusion criteria were selected and reviewed. Ustekinumab 45 mg group and 90 mg group could get better therapeutic effect compared with the placebo group (all P<0.00001). Furthermore, ustekinumab 90 mg group was more effective than ustekinumab 45 mg group (P=0.01). Adverse effects in the 6 trials were mentioned including headache, upper respiratory tract infection, nasopharyngtis, infection, serious infection, cardiovascular events, and malignant tumors. There were no statistically significant differences of these adverse effects among three groups (all P>0.05), except that infection rate in ustekinumab 45 mg group was higher than the placebo group (P=0.02).
Conclusions Ustekinumab is an effective and safe therapeutic method for plaque psoriasis. However, further longer time analysis of safety is needed.

Akt1 is a serine-threonine protein kinase that has been implicated in the control of cellular metabolism,survival and growth.Elevated expression of Akt1 has been noted in a significant percentage of human tumors,promoting cellular metastasis.Conversely,some studies have revealed hyperactivated Akt1 inhibited the invasiveness and metastasis of breast cancer cells.To clarify the definite effect of Akt1 on tumorigenesis and development,Akt1 was silenced by RNAi in the highly metastatic murine breast cancer 4T1 cells.Akt1 silencing didn't affect the proliferation of breast cancer cells in MTT assay,while reduced the migration in Transwell assay.Consistent with the above results,Akt1 silencing didn't change the primary tumor weight,but significantly suppressed lung metastasis of 4T1 cells.These observations indicated Akt1 plays an important role in murine breast cancer metastasis,and suggested that Akt1 might be a therapeutic target for breast cancer metastasis.

Objective To evaluate the efficacy and safety of fully covered self-expandable metal stents (FCSEMS) implanted by endoscopic retrograde cholangiopancreatography (ERCP) for patients with benign biliary stricture (BBS).Methods The clinical data of 38 patients with BBS underwent ERCP and FCSEMS placement between January 2012 and January 2016 were retrospectively recorded.Success rate of BBS,adverse events related to ERCP and stricture recurrence were analyzed.Results A total of 38 patients underwent FCSEMS placement with a mean time of stent in dwelling for 8 months (range:3-13months).During follow-up after the stent was removed,death of 1 patient after liver transplantation was due to unrelated cause.The mean follow-up time was 13 months (range:2-52 months) for other patients.Stricture recurrence occurred in 6 patients,including 2 cases of gallstone-related biliary strictures,1 case of chronic pancreatitis-related biliary strictures,2 cases of liver transplantation-related biliary strictures,and 1 case of post surgical-related biliary strictures.Stricture resolution occurred in 31 cases with 83.8％ (31/37) success rate,including 90.0％ (18/20) gallstone-related biliary strictures,75.0％ (3/4) chronic pancreatitis-related biliary strictures,80.0％ (8/10) liver transplantation-related biliary strictures,and 66.7％ (2/3)post surgical-related biliary strictures.The incidence of post-ERCP complications was 21.1％ (8/38),including mild pancreatitis in 5 case,hyperamylasemia in 2 cases,cholangitis in 1 case.All patients were cured by conservative treatment.Conclusion FCSEMS are effective and safe for BBS.Further studies are needed to assess the indwelling time of FCSEMS,whether FCSEMS are superior to multiple plastic stents and the different efficacy of FCSEMS for BBS caused by different etiology.

OBJECTIVETo discuss the indication and outcome of volar Barton fracture treated by nonoperative method.

METHODSTwenty-three cases of volar Barton fracture treated by closed method included 8 male and 15 female with an average age of 52.2 years,ranging 16 to 84 years. Among them, 16 cases showed subluxation of the carpus (15 cases were Mehara type I ,1 case was Mehara type III) by radiographs except the other 7 cases. By the experimentation in 32 cadavers, the injury of dorsal radiocarpal ligament was supposed to be a very important cause of the subluxation of the radiocarpal joint. The criteria of Pattee and Thompson was used to evaluate the outcome of the treatment.

RESULTSTwenty-three patients were followed up for 7 to 70 months, 11 cases gained satisfactory outcome (1 case as excellent, 10 cases as good), 12 cases gained unsatisfactory outcome (5 cases as fair, 7 cases as poor). Five of 7 cases without the subluxation of the carpus by the radiographs gained satisfactory outcome. Six of 16 cases with the subluxation of the carpus gained satisfactory outcome.

CONCLUSION(1) The result of reduction will influence the outcome of the treatment, the step on articular surface shoud be less than 2 mm after reduction. (2) Nonoperative method is recommended if volar Barton fractures are not associated with subluxation of the carpus. (3) Nonoperative method can be tried first if the fractures associated with the subluxation of the carpus, however operation is recommended when the articular step is more than 2 mm.

Objective To explore the growth and developmental parameters and behavioral characteristics of rhesus monkeys during the first year of birth and to establish the background data.Methods A total of 18 (♂=11,♀=7 ) infant rhesus monkeys born from individually caged mothers and with known genetic background and postnatal days were monitored monthly for body weight, body height, head circumference, chest circumference, forelimb length, hind limb length, crown-rump length, tail length and anal-genital distance from postnatal day ( PND) 1 to 360, while hematology, blood chemistry and lymphocyte subsets were examined on PND 28, 175 and 360, and finger maze test was carried out on PND 208.Results The body weight showed linear growth with no significant difference between genders (P>0.05). Except for the anal-genital distance of male infants was significantly greater than that of female infants ( P<0.01 ) , no significant differences were observed between sexes in other morphological parameters.No significant differences of hematology were seen between genders (P >0.05).Compared with that at PND28, TP and BUN were significantly increased (P<0.01) while ALP decreased with no significant difference (P>0.05) at PND 175 and 360.Compared with that at PND28, CD4 +and CD4 +/CD8 +were significantly decreased ( P<0.01) while CD8+significantly increased ( P<0.01) at PND175 and 360.The number of sessions to solve task 2 in learning test was significantly greater than other tasks with females significantly less than males ( P<0.05) .The females had higher correct rate than males in the 2-day random memory test (P<0.05).Conclusions Body weight and morphological parameters show a linear growth.The PND.The RBC, HGB, LYMPH, TP, BUN, ALP, CD4 +, CD8 +and CD4 +/CD8+in hematology, blood chemistry and lymphocyte subsets show relevant changes to the growth and development of organs and systems in infants, which should be highly concerned in drug evaluation.The finger maze test indicates that female infants have better reversal learning and long-term memory than male infants.Background data and behavioral characteristics of infant rhesus monkeys during the first 12 months of birth are established in this study, which provide useful reference and support the evaluation of developmental and reproductive toxicity of drugs in rhesus monkeys.

OBJECTIVETo observe the effect of novel air neuromodulator H2S on platelet function of L-Arg transport for discussing H2S of effect on platelet function.

METHODSSaturate H2S solution as donate made rat rich platelet plasma and pre-incubation rat platelet with different density of H2S. To measure the velocity of L-Arg transport in platelet by radioactivity technique.

RESULTSAt different concentrations of H2S (6.25, 12.5, 25, 50, 100 micromol/L), the velocity of L-Arg transport was lower than that in control. H2S reduced rapidly the Vmax and velocity of L-Arg transport in platelet (P < 0.05) and this effect had no effect to Km.

CONCLUSIONH2S can affect platelet function by changing rapidly platelet L-Arg transport system function.

OBJECTIVETo explore the effects of soothing liver and invigorating spleen recipes on lipopolysaccharide(LPS) induced hepatocyte inflammation of rats and TLR4/p38MAPK signal pathway.

METHODThe hepatocytes of SD rats were cultured and identified in vitro. The medicated serum of soothing liver and invigorating spleen recipes was prepared. The hepatocytes were treated with soothing liver and invigorating spleen recipes. Then Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression in cultural supernatants were assayed by ELISA. The expressions of Toll-Like 4 (TLR4), p38 mitogen activated protein kinases (p38MAPK) and p-p38 mitogen-activated protein kinase (p-p38MAPK) were detected by Western blot.

RESULTThe rat medicated serum of soothing liver and invigorating spleen recipes was extracted for 2-3 mL. The purified rat hepatocytes were 1.5 x 10(8)-2.0 x 10(8). The cell viability was above 95% detected by Typan blue staining. The hepatocytes were identified by immumofluorescence assay. The detection of hepatocyte cultural supernatants: compared with that of the control group, IL-6 and TNF-α expression were increased in the LPS group (P < 0.01). While compared with that of the LPS group, the expressions of IL-6 and TNF-α were decreased after soothing liver and invigorating spleen recipes intervention (P < 0.01). The detection of hepatocyte proteins: compared with that of the control group, the protein expressions of p38MAPK, p-p38MAPK and TLR4 were all increased significantly in the LPS group (P < 0.01). Compared with that of the LPS group, the protein expressions of p38MAPK was decreased significantly in SB239063 group and it was also decreased in the soothing liver and invigorating spleen recipes group, but with no significant difference. Compared with that of the LPS group, p38MAPK expression was reduced significantly in the soothing liver and invigorating spleen recipes group and the SB239063 (p38MAPK pathway inhibitor) group (P < 0.01). TLR4 protein expression was decreased markedly in the soothing liver and invigorating spleen recipes group (P < 0.01) but had no difference between the SB239063 group and the LPS group.

CONCLUSIONThe soothing liver and invigorating spleen recipes may regulate hepatocyte inflammatory injury of rats through TLR4/p38MAPK signaling pathway.

Objective To evaluate the clinical results of indirect reduction and fixation with the self-manufactured external fixator as a viable alternative in the surgical treatment of intraarticular calcaneal fractures.Methods From May 2006 to May 2009,a total of 30 patients undergone surgical treatment of intraarticular calcaneal fractures were analyzed,including 20 males and 10 females with an average age of 36 years (range,15-53).According to Sanders classification based on the computed tomography scan of intraarticular calcaneal fractures,16 patients were classified as type-Ⅲ,and 14 type-Ⅳ in this series.All fractures were treated first with the external fixator as indirect reduction and fixation device on the whole,which can enlarge the interspace of the subtalar joint significantly.Then,posterior articular facet of calcaneus was exposed and reduced through a small lateral incision.The calcaneal's length,breadth,thalamus height,maximum vertical displacement of the post-articular surface,and B(o)hler angle were measured preoperatively,3 days and 6 months after operation in X-ray film.Reduction results were evaluated by CT scan according to the standard of Buckley.Results The average follow-up time of all patients was 29 months (range,4-45).Lateral and axial roentgenograms showed satisfactory restoration of the calcaneal's anatomical structure.There were significant differences between preoperative values and those 3 days or 6 months postoperatively.There were no significant differences between values 3 days postoperatively and those 6 months postoperatively.The reduction results of posterior articular facet were evaluated by CT scan.Twenty-seven patients obtained anatomical reduction,3 patients obtained uneven articular facet within 2 mm.Conclusion This selfmanufactured external fixator is a vialbe alternative in the treatment of intraarticular calcaneal fractures,which has advantages of minimal invasion,practicality and less complications.

OBJECTIVETo compare the difference between J-hook and micro-implant anchorage in the treatment of patient with bimaxillary protrusion.

METHODSThirty patients with bimaxillary protrusion were divided into two groups (J-hook and micro-implant groups) and treated with MBT appliance. Four first premolars were extracted in all patients. Cephalometric analyses were carried out before and after treatment.

RESULTSIn J-hook group and micro-implant group,computerized cephalometric analysis revealed that before treatment U6C-PP was (12.4 +/- 0.2) mm and (12.5 +/- 0.1) mm, respectively,and after treatment U6C-PP was (12.6 +/- 0.1) mm and (12.8 +/- 0.1) mm,respectively. The difference between J-hook group and microimplant group was significant (P < 0.01). The other differences of cephalometric analyses between J-hook group and micro-implant group was not significant.

CONCLUSIONSBoth J-hook and micro-implant could provide adequate anchorage in the treatment of patients with bimaxillary protrusion.
