Objective To study the clinical therapeutic effectiveness and the mechanism of Shouti Oral Liquid on simple obesity children with hyperinsulinism. Methods Fourty - three patients were divided randomly into the treatment group (TG) and the control group (CG). TG took Shouti Oral Liquid and CG took metformin. The course of therapy lasted 6 months. The plasma lipid, body fats, insulin resistance index (IR) and some hormones related to obesity before and after therapy were measured and the changes were analyzed. Results The weight, F% , body mass index (BMI), leptin(LP), tumor necrosing factor (TNF - ?), FINS, IR all declined markedly than pre - therapy in both groups. The significant effect, normal effect and total efficiency were 22.7 % , 59.1 %, 81.8 % respectively in TG and9.5%,52.4%,61.9% in CG. The effect in TG was better than that in CG. A short course with Shouti Oral Liquid therapy did not have obvious side effect Conclusions There are lipid metabolism disorder, insulin resistance and high lever LP and TNF - ? obesity children with hyperinsulinism. The total effect with Shouti Oral Liquid is better than that with medicine in the control group and the mechanism was regulating lipid metabolism, decreasing LP and TNF-? and ameliorating insulin resistance.

Objective To investigate the in vitro inhibitory effects of regulatory T cells ( Treg ) from unpregnant mice and pregnancy-induced regulatory T cells ( piTreg) on the proliferation of na?ve T cells and their differences .Methods The numbers of piTreg cells from allogeneic pregnant mice ( C57/B6 fe-male×BALB/c male) on day 12.5 (E12.5d) of gestation and Treg cells from unpregnant C57/B6 mice were detected respectively by flow cytometry .The percentages of piTreg cells and Treg cells in CD 4+T cells of age-matched female mice and their intracellular expression of Foxp 3 were analyzed .The in vitro inhibitory effects of piTreg cells and Treg cells on the CFSE-labeled na?ve T cells ( effector cells ) were compared in a one-way mixed lymphocyte culture system using mitomycin C-inactivated CD4-T cells as stimulator cells . Results The level of piTreg cells in splenic mononuclear cells was significantly higher than that of Treg cells (P<0.001) from normal mice.Foxp3 was highly expressed in both piTreg cells and Treg cells , howev-er slightly increased in piTreg cells .Moreover , piTreg cells had a significant stronger in vitro inhibitory effect on na?ve T cells proliferation than that of Tregs cells (P<0.006), which was in a cell-dependent manner. Conclusion The present study suggests that the piTreg cells have a stronger inhibitory effect on na ?ve T cell proliferation as compared with Terg cells from unpregnant mice , The differential activity of CD 4+CD25+Treg might be mediated by the paternal antigens during pregnancy .

OBJECTIVETo assess the clinical effectiveness of volar and radial column approach by plate fixation for the treat- ment of unstable fracture of distal radius.

METHODSAccording to Cochrane Systematic Review, Medline, Embase, Cochrane Li- brary, CNKI and CBM, randomised controlled trials (RCTs) of volar and radial column approach by plate fixation for the treat- ment of unstable fracture of distal radius were searched for from 1966 to 2014. Data analysis was performed with the Cochrane Collaboration's RevMan 5.0 software.

RESULTSTotally 391 patients of 6 RCTs and 2 retrospective cohort studys were included and divided into volar plate group (187 cases) and radial column plate group (204 cases). Meta-analysis result showed: compared with radial column plate group, volar plate group had significant difference in recovery of wrist function [SMD = 0.74, 95% CI (0.47, 1.01), P < 0.00001], Gartland-Werley scores [SMD = -1.39, 95% CI (-2.24, -0.53), P = 0.001], postoperative neural in- jury [OR = 3.67, 95% CI (1.37, 9.84), P = 0.01 1 and postoperative wrist pain [OR = 0.32, 95% CI (0.13, 0.74), P = 0.008]. But no significant difference was identified in DASH scores [SMD = -0.36, 95% CI (-0.97, 0.26), P = 0.25], radiographic result assess- ment [SMD = -0.18, 95% CI (-0.53, 0.16), P = 0.3], postoperative grip strength [SMD = 0.71, 95% CI (-0.12, 1.54),P = 0.09], postoperative tendinous damage [OR = 0.31, 95% CI (0.10, 0.98), P = 0.05] and carpal tunnel syndrome [OR = 0.96, 95% CI (0.63, 1.48), P = 0.87].

CONCLUSIONCompared with radial column plate internal fixation, volar approach plate fixation for treat- ment of distal radius intra-articular fracture has advantage of recovery of joint functionand. However, the volar approach plate fix- ation was associated with a higher risk of long-term complications than the radial column approach plate fixation.

OBJECTIVETo explore the correlation between the recurrence of cerebral infarction and aspirin resistance (AR)/Chinese medical (CM) constitutions.

METHODSTotally 413 cerebral infarction patients took Aspirin Enteric-coated Tablet (100 mg per day) while receiving routine therapy, 5 days at least in a week. They were followed-up for 12 months. Aspirin sensitivity (AS) was determined using turbidimetry. CM constitutions among patients with different AS were compared. Ratios of AR patients and AS patients of different CM constitutions in cerebral infarction recurrent patients were compared. Platelet membrane glycoproteins (GP) II b HPA-3 gene polymorphism was detected by polymerase chain reaction (PCR) method. Correlation between recurrence of cerebral infarction and AR, bb genotypes, CM constitutions times AS were analyzed by Logistic regression.

RESULTSTotally 11 patients dropped out, 101 (25.12%)with recurrent cerebral infarction and 301 (74.88%) without recurrent cerebral infarction. There were 152 (37.81%) AR patients and 250 (62.19%) AS patients. AR accounted for 26.6% (80/ 301) and AS accounted for 73.4% (221/301) in non-recurrent cerebral infarction patients. AR accounted for 71.3% (72/101) and AS accounted for 28.7% (29/101) in recurrent cerebral infarction patients. There was statistical difference in AR and AS ratios (χ2 = 64.287, P = 0.000). The proportion of yin deficiency constitution (YDC) was the largest [28.3% (43/152)] in AR patients. The proportion of blood stasis constitution (BSC) was the largest [23.6% (59/250)] in AS patients. There was statistical difference in CM constitutions between AR patients and AS patients (χ2 = 21.574, P < 0.01). The former 4 recurrent rates occurred in AR patients of YDC, BSC, damp-phlegm constitution (DPC), qi deficiency constitution (QDC). YDC occupied the first place [22.4% (34/152)]. The former 4 recurrent rates occurred in AS patients of BSC, QDC, DPC, damp-heat constitution (DHC). BSC occupied the first place [3.2% (2/250)]. Compared with non-recurrent cerebral infarction patients and AS patients, bb gene occurred most often, but aa gene and ab gene occurred obviously lesser in non-recurrent cerebral infarction patients and AR patients (χ2 = 20.171, χ2 = 55.139, P < 0.01). AR and bb gene were positively correlated with recurrent cerebral infarction (OR = 18.423, P = 0.000; OR = 1.304, P = 0.028). Body constitutions interacted with AS (OR = 0.707, P = 0.000).

CONCLUSIONSRecurrent cerebral infarction was closely related to AR and constitutional types. The recurrence rate was higher in AR patients of YDC. GP I b HPA-3 bb genotype might be a risk factor for AR and recurrent cerebral infarction.

OBJECTIVETo investigate the effects and mechanisms of sodium ferutate (SF) in treating diabetic nephropathy (DN).

METHODSEighty patients of diabetes mellitus type 2 with DN were randomly divided into two groups, 40 cases in each group. The routine group treated with conventional treatment including dietary therapy and hypodermic injection of insulin, and the SF group treated with intravenous dripping of SF 300 mg/d additionally besides the conventional therapy, the therapeutic course for both groups was 4 weeks. And 40 healthy volunteers were allocated in a group for normal control. Before and after therapy, levels of fasting blood glucose (FBG), hemoglobin A1c(HbA1c), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL-C), serum creatinine (SCr), blood urea nitrogen (BUN), mean arterial pressure (MAP), urinary albumin excretion rate (UAER), serum collagen type IV (CIV) and endothelin (ET) were detected.

RESULTSAfter 4 weeks of treatment, FBG and HbA1c reduced obviously in both groups with insignificant difference in comparison of them (P > 0.05). Before treatment, TG, TC, MAP, SCr, BUN, UAER, CIV and ET were markedly higher in DN patients than those in the health control (P < 0.05), these criteria decreased significantly in the SF group (P < 0.05) but insignificantly in the routine group (P > 0.05) after treatment, showing difference between the two groups (P < 0.05).

CONCLUSIONSodium ferulate could ameliorate lipid metabolic disorder, reduce blood pressure, lower UAER and CIV level, and improve renal function in DN patients, the mechanism might be through decreasing ET production and inhibiting the combining of ET with its receptor.

Objective To investigate if rat enhancer of split- and hairy-related protein-2 (SHARP-2) short hairpin RNA interference (shRNAi) prolongs the survival time of rat kidney transplant recipients. Methods Gene recombinant procedures, transfection and co-transfection were carried out to introduce short hairpin RNA interference sequences target for SHARP-2 into 3rd generation self-inactivated lentiviral-ViraPower packaging mix. Limiting dilution method was used for viral titration. Real-time PCR was employed for quantification of gene expression. Rat kidney transplantation was utilized to investigate the effect of SHARP-2 gene silence on the recipient survival. Results A lentiviral-based shRNAi construct LV-SHARP-2iC showed 84% SHARP-2 gene silence efficiency in normal rat kidney cells. At multiplicity of infection 20, 57% T cells could be transfected by lentivirus with spinoculation method. In activated T cells, SHARP-2 g ene silence resulted in 61.3% and 68.7% reduction of intedeukin 2 (IL-2) and interferon γ (IFN-γ) gene expression. When donor kidney was perfused with 5×107 TU LV-SHARP-2iC, the median survival time prolonged for 4-5 days as compared to blank and scramble control groups. Conclusions A recombinant lentivirus LV-SHARP-2iC that effectively silence SHARP-2 gene expression is constructed successfully, leading to the inhibition of IL-2 and IFN-γ. LV-SHARP-2iC treatment can prolong the survival time of rat kidney transplant recipients.
