Objective To explore the relationship between obesity levels and adipocytokines like leptin,adiponectin and resistin in children.Methods One hundred and ten patients aged 2-6 years with simple obesity were selected into obesity group,which included 40 cases of slight obesity (slight obesity group),40 cases of medium obesity (medium obesity group) and 30 cases of severe obesity (severe obesity group).Forty cases of healthy children with normal bodyweight were included in control group.Their serum leptin,adiponectin and resistin levels were tested and compared.Results Serum leptin and resistin levels in obesity group were remarkably higher than those in control group (P < 0.01),whereas adiponectin level was much lower than that in control group (P< 0.01).Serum leptin and resistin levels in medium obesity group were remarkably higher than those in slight obesity group [(14.3 ±1.9) μg/L vs (7.8 ± 1.5)μg/L and (14.6±2.2) μg/Lvs (13.1 ±3.0) μg/L](P< 0.01),whereas adiponectin level was much lower than that in slight obesity group[(6.7 ± 3.0) mg/L vs (9.1 ± 3.5) mg/L](P< 0.01).Serum leptin and resistin levels in severe obesity group [(20.4 ±4.7),(18.3 ±3.2) μg/L]were remarkably higher than those in medium obesity group(P< 0.01),whereas adiponectin level [(5.1 ± 1.2) mg/L]was much lower than that in medium obesity group (P< 0.01).Conclusion The levels of adipocytokines are closely correlated with obesity level in children,especially for abdominal obesity.

Objective To establish the model of amyotrophic lateral sclerosis (ALS) with selective motor neuron disorder by organotypic spinal cord cultures, and analyze the role of astrocyte in the pathagenisis of ALS.Methods Organotypic spinal cord cultures were prepared using lumbar spinal cord slices from 8-day-old SD rat pups. The threohydroxyaspartate (THA) was applied into culture medium to establish ALS organotypic spinal cord cultures model. Motor neurons survival was evaluated by monoclonal SMI-32 immunohistochemical staining and glial fibrillary acidic protein staining to show astrocyte survival.Results Compared with the control group, there was significantly astrogliosis in the anterior horn and surrounding white matter in THA 100 μmol/L group, and the level of gliosis was increased followed the elongation of THA interference time. With the increasing of the number of astrocyte, the morphology of astrocyte was changed.Conclusion There is significantly astrogliosis in the anterior horn and the time of astrogliosis is markedly earlier than the time of motor neuron loss in the ALS model intervented with THA.

Diabetic nephropathy (DN) is one of the chronic diabetic complications,which often leads to chronic renal failure.The diagnosis of DN involves a comprehensive assessment of clinical,pathological and other manifestations.Early diagnosis is rather important for the prevention of DN.

Signal transducer and activator of transcription 3 (STAT3) is an important member of STATs family and is highly expressed in many kinds of cancer. It regulates the tumor growth by influencing the apoptosis of tumor cells and tumor angiogenesis and becomes a new target for tumor therapy. This article reviews the structure of STAT3, the stimulating factors of STAT3, the tumor growth regulating pathway of STAT3, and its potential as a target for tumor therapy.

OBJECTIVE: To explore the relevance between writing characteristic and therapeutic effect in schizophrenia and to discuss the influence of aggressive behavior on writing characteristic. METHODS: Recoding the casual and fixed writing in admission, one week, two weeks, four weeks, eight weeks after treatment and rating Positive and Negative Syndrome Scale (PANSS) and Modified Overt Aggression Scale (MOAS). Choosing two characteristics, "relationship between font and grid lines" and "having big strokes or not", and comparing before and after treatment. RESULTS: Eight weeks after treatment, the score of PANSS decreased. The condition of patients and the writing characteristic improved as well. The differences of writing characteristics were statistically significant in patients with aggressive behavior before and after treatment (P < 0.05). CONCLUSION The writing characteristic has relation with therapeutic effects and improved with therapeutic effects in aggressive patients.

Aim To study the expression of caspase-12 mRNA and protein following focal cerebral ischemia-reperfusion in rats,and explore the effect of endoplasmic reticulum pathway on neuronal apoptosis.Methods 60 male Wistar rats were randomly divided into sham-operated group and ischemic group.The middle cerebral artery occlusion(MCAO)models were established by using the intraluminal suture occlusion method,neuronal apoptosis was detected by TUNEL staining,the expression of caspase-12 protein was detected by immunohistochemical staining,the expression of caspase-12 mRNA was detected by RT-PCR method.Results In ischemic group,the number of apoptotic cells and the expression of caspase-12 mRNA and protein were gradually increased following prolonged cerebral reperfusion,reached the peak at 24 h.The number of apoptotic cells and the expression of caspase-12 mRNA and protein in ischemic group were significantly less than those of sham-operated group at all times(P

Objective To explore the effects of exercise training(ET)on the functional recovery of nerves (NFR)in rats with intracerebral hemorrhage(ICH).Methods Ninety Sprague-Dawley rats were randomly divided into an ET group,a control group and a sham operation group(SO group).An ICH model was established with colla- genase in the ET and control groups,while sodium chloride was used with the SO group.The ET group exercised for 40 min a day from 24 h to 30 d after the operation.Attitudinal reflexes,balance function and muscle strength were assessed at 24 h,3 d,7 d,14 d,21 d and 28 d after the operation.Results Compared with the control group, NFR values were increased significantly in the ET group,and there was no obvious dysfunction in the SO group. Conclusion Early ET can contribute to functional recovery after ICH.

Objective To investigate the clinical and laboratory features of male patients with anti-phospholipid syndrome (APS).Methods Thirty-three male APS patients admitted to Peking University People's Hospital from January 2003 to April 2015 were enrolled.One hundred and fourteen female APS patients were selected as controls.Female patients with thrombosis were analyzed.x2 test, Fisher's exact test and t test were used for statistical analysis.Results Among male patients, 39.4％ were primary APS and 60.6％ were secondary APS.Compare with female patients,the prevalence of venous thrombosis was significantly higher than that in male APS (72.7％ vs 29.8％,x2=19.719, P=0.000).The male APS patients experienced more episodes of thrombosis (75.8％ vs 22.8％, x2=31.669, P=0.000) and not less than two locations of thrombosis than female (69.7％ vs 22.8％, x2=25.321, P=0.000), there was still significant difference between male patients and female patients with thrombosis.There was no difference of antiphopholipid antibodies between the two groups.Conclusion Male patients with antiphospholipid syndrome are more prone to have thrombosis.More clinical interventions should be implemented in male patients with APS.

Background Research determined that hypoxia inducible factor-1(HIF-1)is associated with the hypoxia response in normal organ,and it plays an important role during the embryon development.It is also proved that the expression of vascular endothelial growth factor(VEGF)is upregulated in embryon retina.But,whether the action of HIF-1 and VEGF is correlated is unclear. Objective The aim of this study was to investigate the dynamic change of expression of HIF-1α and VEGF in retina during embryonic development and explore the role of HIF-1α and VEGF along with retinal evolvement.Methods The different embryon ages of SD rats were obtained from 30 clean pregnant SD rats by cesarean surgery.The retinas were isolated from embryon 10一day,12一day,14-day,16-day and 20-day rats respectively.The expressions of HIF-1 α and VEGF protein in retina were semi-quantitatively and qualitatively determined by immunochemistry,and the expressions of HIF-l α and VEGF mRNA in retina with different-embryon-phase and adult rats were detected by RT-PCR. Results The hishly level of expression of HIF-1 α and VEGF protein were found in the cellular nuclei and cytoplasm of retina in embryon 10一and 12-day rats.With the increase of embryon age.the expression of HIF-1α and VEGF protein in retina lowed(F=56.70,P<0.01；F=60.78.P<0.01).Compared with the adult rats,the expressions of HIF-1α and VEGF protein in retina were higher from embryon 0-day through 20-day rats(all P<0.01).The significantly positive correlation was found in the expression level between HIF-1α and VEGF protein throughout the experimental duration(r=0.96,P=0.00).Followed the same pattern,the expression levels of HIF-1α and VEGF mRNA in retinas were also enhanced in the embryon 10- and 12-day rats.Identically,a gradually weakened trend was seen in the expressions of HIF-1 α and VEGF mRNA in retinas as the increase of gestational age of rats(F=68.84,P<0.01；F=96.49,P<0.01),and the exDressions of HIF-1 α and VEGF mRNA decreased in the adult rats compared with different embryon-phase rats,showing a statistically significant difference between them(all P<0.01). Conclusion The expressions of HIF-1 αand VEGF in retina appear a dynamic alteration from hish to low during the embryonic development of rat retina,indicating that HIF-1α/VEGF pathway might participate in the process of embryo development of rat retina.
