Objective To study the changes of interleukin-4(IL-4),IL-6,IL-8 in children with idiopathic thrombocytopenic purpura(ITP).Methods The serum of IL-4,IL-6,IL-8 in 35 ITP patients and 20 normal control children were detected by enzyme-linked immunosorbent assay.Results The serum IL-4,IL-6,IL-8 in ITP patients were elevated. There were significant difference between ITP group and control group(P

One hundred and seventy-two strains of endophytic fungi were isolated from Taxus mairei,Cephalotaxus fortunei and Torreya grandis cv.merrillia.The result of the antifungal assay shows that ninety strains of the fungi have antagonism against one or more botanical pathogenic fungi,such as Neurospora sp.,Trichoderma sp.,Fusarium sp.etc.The percentage of antifungal strains to tested strains are as follows:40% Cephalotaxus fortunei,54.2% Taxus mairei,57.1% Torreya grandis cv.merrillia.Thirty-five strains have high antifungal activities,and their inhibition zone diameter is at least 15mm.The active endophytic fungi were identified as 18 genera,most of which belong to Paecilomyces and Fusarium etc.

Objective To evaluate the clinical outcome and relative factors of intervention treatment for atherosclerotic renal artery stenosis in elderly patients.Methods The clinical data of 79 patients diagnosed as atherosclerotic renal artery stenosis by angiography and treated by revascularization were analyzed.Results There were 55(69.6%)successes and 24(30.4%)failures in decreasing blood pressure and 28(35.4%)successes and 51(64.6%)failures in improving renal function after intervention treatment.Predictors of favorable outcome of intervention treatment in decreasing blood pressure were related to lower urine protein,higher glomerular filtration rate,higher systolic and diastolic blood pressure before treatment,lower resistance index(RI)of renal artery,and no complication of cerebral vascular diseases.Predictors of favorable outcome of intervention treatment in improving renal function were related with percentage of angiographic stenosis,category of antihypertension and lower urine protein.The logistic regression analysis showed that the percentage of angiographic stenosis was the most important predictor of intervention treatment for blood pressure control,age and level of serum creatinine before intervention treatment were the most important predictors of intervention treatment for improving renal faction.Conclusion Percentage of stenosis(≥85%),age(133 ?mol/L)can be used as the predictors of therapeutic success for renovascular stenosis in older patients.

Human herpesvirus 7 (HHV-7) infection is dependent on the functions of structural glycoproteins at multiple stages of the viral life cycle. These proteins mediate the initial attachment and fusion events that occur between the viral envelope and a host cell membrane, as well as cell to cell spread of the virus. To characterize the HHV-7 glycoproteins that can mediate cell fusion, a cell-based fusion assay was used. 293T cells expressing the HHV-7 glycoproteins of interest along with a luciferase reporter gene under the control of the T7 promoter were cocultivated with SupT1 cells transfected with T7 RNA polymerase. HHV-7 glycoproteins gB, gH, gL and gO can mediate the fusion of 293T cells with SupT1 cells, and the fusion can be inhibited by anti-CD4 mAbs. Thus, the coexpression of HHV-7 gB, gO, gH and gL is sufficient and necessary for HHV-7 induced membrane fusion, and one of these glycoproteins or protein complex formed by these glycoproteins might be the ligand(s) of CD4 molecule.

AIM:To observe the efficacy of intravitreal conbercept injection for chronic central serous chorioretinopathy (CSC).METHODS: Nine eyes of 9 patients diagnosed as chronic CSC between October 2015 to May 2016 were treated with an intravitreal injection of conbercept (0.5mg/0.05mL) (six patients were given the same does of intravitreal injection again at 1mo after the first injection).Follow-up observation was at 1, 2, and 6mo after injection.Observed indicators included best-corrected visual acuity (BCVA), intraocular pressure, optical coherence tomography (OCT), fundus fluorescein angiography (FFA), choroidal indocyanine green angiography (ICGA), macular fovea thickness (CMT), subfoveal choroidal thickness (SFCT).RESULTS:Seven of the 9 patients responded significantly to the drug, while 2 patients had no response.The CMT was 373.12±72.43μm at baseline, which decreased significantly to 332.05±67.13μm, 282.24±62.30μm and 225.56±71.08μm at 1, 2 and 6mo after the intravitreal injection.The mean thickness of SFCT was 422.11±64.82μm before treatment.The choroidal thickness of non-responsive patients before treatment was below average, respectively 353μm and 365μm.The SFCT of 1, 2, and 6mo after treatment was 391.45±75.24μm, 365.53±63.07μm, 355.40±66.65μm.Before treatment and 1mo after, there was no significant difference (P=0.074), but there was statistically significant (P<0.01) between those of before and 2mo and 6mo after.The mean BCVA of the prior treatment was 0.53±0.32, the after treatment was 0.65±0.20, there was no different between the two(P>0.05).CONCLUSION: Intravitreal conbercept injection in chronic CSC may have some effect in accelerating subertinal fluid resolution and decreasing the CMT.The SFCT within 6mo after treatment was significantly lower than pretreatment.The SFCT may be an indicator of whether patients respond.

OBJECTIVE: To observe the expression of discs large homolog 4 (DLG4) protein in hippocampus, amygdala and frontal cortex of rats and evaluate postsynaptic density in heroin dependence. METHODS: The rat heroin dependent model was established by increasing intraperitoneal injection of heroin. DLG4 proteins in hippocampus, amygdala and frontal cortex of heroin dependent 9, 18, 36 days rats were detected with immunohistochemical staining and compared with that in the control group. RESULTS: DLG4 proteins in hippocampus, amygdala and frontal cortex were gradually reduced with extension of heroin dependent time. CONCLUSION Heroin dependence can affect postsynaptic density of hippocampus, amygdala and frontal cortex. The changes become more apparent with extension of heroin dependence time.

OBJECTIVETo compare mid-term clinical outcomes between amputation and limb salvage in treating severe open tibial fractures with type Gustilo III B, III C.

METHODSFrom July 2007 to June 2010,68 patients with severe open tibial fractures with type Gustilo III B, III C treated by amputation and limb salvage were retrospectively analyzed. In amputation group, there were 26 males and 12 females with an average age of (44.9±16.3) years old; and 21 cases were type Gustilo (III B, 17 cases were Gustilo III C; amputation were performed in accordance with soft tissue injury degree of shank, fracture types and surgical exploration. In limb salvageg group, there were 21 males and 9 females with an average age of (43.5±14.7) years old; and 23 cases were type Gustilo III B, 7 cases were Gustilo III C; the method of internal fixation and and wound healing were performed in accordance with patients's specific condition. Operative time, blood loss, hospital stay and postoperative infection was compared between two groups; time of loading and rate of return to work was compared; VAS scoring was used to evaluate condition of pain; SF-36 health queationaire was used to assess postoperative life quality.

RESULTSTotally 60 patients were followed up (33 cases in amputation group and 27 cases in limb salvage group) with an average time of 49.1 months. Operative time, blood loss, hospital stay and postoperative infection in amputation and limb salvage group respectively was (109.0±25.7) min, (245.0±58.6) min; (168.0±49.0) ml, (311.0±137.0) ml; (13.8±2.7) d, (28.8±13.1) d; 7.9%, 36.7%. At the final following-up, there was no significance meaning between two groups in VAS scoring and rate of return to work, but time of loading in amputation group was shorter than that of in limb salvage group. Physiological function in amputation group was better than limb salvage group, while body pain was worse; and there was no signicance meaning in psychological health between two groups.

CONCLUSIONAmputation and limb salvage both can treat severe open tibial fractures, and mid-term clinical outcomes between two groups has equivalent efficacy.

Objective To investigate the relevant risk factors for fungal infection following operation of the gastrointestinal neo- plasm and offer supporting data for the prevention of fungal infection.Methods Medical records from 116 patients who under- went the operation of gastrointestinal neoplasm in the special group of this hospital from January 2006 to June 2006 were retro- spectively reviewed on the relevant risk factors by univariate and multivariate Logistic regression analysis.Results Of the 116 patients reviewed, 18 had fungal infection.Forty-six samples were positive for fungal pathogen.The most frequently isolated fungal strain was Candida albicans (15/20) and the most common infection site was gastrointestinal tract (14/18).Fungal in- fection after the operation of gastrointestinal neoplasm was significantly relevant with the duration of antibiotic use, duration of post-operative fasting, low serum albumin, high blood glucose and complication of bacterial infection.The duration of antibiotic use was a significantly independent risk factor.Conclusions Reasonable antibiotic use, nutritional support, early enteral nutri- tion and control of blood glucose should be taken into account after the operation of gastrointestinal neoplasm in order to prevent fungal infections.

AIM: To investigate the effect of DDP and ADM on cell cycle in leukemia cell line K562. METHODS: The change of cell cycle was observed by means of flow cytometry after different interval in which the K562 cells were treated with DDP and ADM. RESULTS: K562 cells attested at S phase after treated 36 hours with DDP at concentration of 10 ?mol/L or 48 h with ADM at concentration of 1 36 ?mol/L. K562 cells attested at G 1 phase after treated 24 h with DDP at concentration of 20 ?mol/L or at G 2/M phase after treated with ADM at concentration of 0 17 ?mol/L. CONCLUSIONS: K562 cells showed different patterns to change the cell cycle induced by DDP and ADM with different concentrations at different time, which reflected that different checkpoints of cell cycle were activated at different conditions.
