Objective To investigate the serum adiponectin levels and TNF-? levels in women with gestational diabetes and to study their clinical significance.Methods Plasma concentration of adiponectin,tumor necrosis factor alpha and correlate parameters were measured in 50 patients with gestational diabetes(GDM)and 36 pregnant women with normal glucose tolerance(NGT).Radio immunoassay was used to measure the adiponectin,TNF-? level was measured by ELISA.Serum insulin level was measured by Electrochemiluminescent immunoassays fasting glucose levels by glucose oxidase method.Results GDM patients had significantly lower concentrations of adiponectin(10.3?(2.4) mg/L) and elevated levels of TNF-?(4.6?(1.5)?g/L) in comparison to NGT women.In GDM group TNF-? level was correlated positively with serum insulin level,glucose level.Concentration of adiponectin was negatively correlated with corresponding parameters.Conclusion Elevated level of TNF-? and decreased adiponectin concentration may not simply reflect maternal adiposity and insulin resistant state,but may contribute to the impaired glucose metabolism during pregnancy and forecast the risk of metabolism syndrome.

BACKGROUND:After cerebral tissue ischemia and anoxia in young rats,the cerebral edema gets serious, and the levels of nitric oxide (NO) and malondialdehyde (MDA) decrease. Radix Astagali seu Hedysari has the pharmacological effects of enhancing immunity, anti-anoxia and improving myocardial ischemic reinfusion injury.OBJECTIVE: To investigate the influences of Radix Astagali seu Hedysari (huangqi) on contents of NO and MDA in brain tissue of young rats with cerebral injury after cerebral ischemia and anoxia.DESIGN:A randomized and controlled trial.SETTING: Department of Pediatrics, Second Hospital, Hebei Medical University; Department of Internal Medicine, Institute of Traditional Chinese Medicine, Hebei Medical University; Department of Pathophysiology, Hebei Medical UniversityMATERIALS:The experiment was conducted from January to April 2004at Department of Pathophysiology, Hebei Medical University. Total 40 SD rats, 7-day old, were at random divided as normal control group, model group, humgqi low-dose group and huangqi high-dose group, with 10 rats in each group. Huangqi injection (The content in 10 mL injection is consistent with 20 g raw drug) was provided by Institute of Traditional Chinese Medicine of Hebei Medical University (produced in Chengdu Di'ou Jiuhong Pharmaceutical Factory, Batch No. 0005028).METHODS:Except rats in normal group, those in the rest groups, under conscious and local anesthesia, were all given common carotid artery ligation, establishing cerebral injury model due to ischemia and anoxia. Rats in normal group were intraperitoneally injected 0.1 mL normal saline; rats in model group were intraperitoneally injected 9 g/L normal saline, 0.1 mL each day; rats in huangqi low-dose group and huangqi high-dose group were respectively given 0.1mL, 0.5 mL huangqi injection, once a day, intraperitoneally. Cerebral blood flow was detected immediately, 2 and 4days after injection. Then the rats were decapitated for collecting the brains to measure the water content in brain, the contents of NO and MDA.MAIN OUTCOME MEASURES: [1] Water contents in brains of rats in every group. [2] Cerebral blood flow, and the contents of NO and MDA.RESULTS:Totally 40 rats were involved in the trial and all entered in the final result analysis. [1] The water content in brain of each group: Compared with normal group, the content in model group was increased immediately after model establishment [(87.316±0.275)%, (88.259±0.297)% ,P ＜ 0.05 ],and did not return to the normal level at the second day [(86.973±0.265)%,(88.173±0.445)%,P ＜ 0.05]; compared with model group, the content in huangqi high-dose group was obviously decreased at second day[(88.173±0.445)%, (86.542±0.141)% ,P ＜ 0.05]. [2] Measurement of cerebral blood flow: compared with control group, the blood flow in model group was obviously decreased immediately after model establishment[(231.88±13.33), (139.54±10.58)mV,P＜ 0.05], and did not return to normal level till the 4th day [(234.57±14.38), (145.38±13.33)mV,P ＜ 0.05];compared with model group, the blood flow in huangqi low-dose group and huangqi high-dose group, at day 4, was obviously increased [(145.38±13.33),(288.45±12.89), (313.82±21.74)mV,P ＜ 0.01]. [3] The contents of NO and MDA: The contents in model group, immediately after model establishment, were obviously higher than those in normal control group [(26.55±5.23 ), ( 19.67±7.17 )μmol/L,P ＜ 0.05; (7.88±2.55), (4.22±0.12) μmol/L, P＜ 0.01], and at day 4, were significantly higher than those in normal control group [(48.65±17.06), (18.65±2.12)μmol/L,P ＜ 0.01; (5.29±0.68),(4.06±0.39)μmol/L,P ＜ 0.05]; compared with model group, the contents in huangqi low-dose group and huangqi high-dose group were obviously decreased at day 4 [(48.65±17.06), (23.77±12.79), (24.67±11.54)μ mol/L,P＜ 0.01; (5.29±0.68), (4.51±2.30), (3.68±0.39)μmol/L,P ＜ 0.01].CONCLUSION:Huangqi could obviously reduce cerebral edema from ischemia and anoxia, increase cerebral blood flow. It could decrease the contents of NO and MDA that is metabolite of free radical injury, thus playing its role to inhibit lipid peroxidation injury.

Objective To study the effect of Chinese wild rice diet on lipid metabolism in rats. Method Forty four male SD rats were divided into 4 groups:control group, high lipid group, white rice-flour group and Chinese wild rice group. All groups were given different experimental diets for 8 w and body weights, serum TC, TG, HDL-C, high sensitive C-reactive protein (hs-CRP), TNF-? and IL-6 were measured. Results The hyperlipidemic rat model was successfully induced. When compared with high lipid group and white rice-flour diet group, serum TG and TC contents were significantly decreased, and HDL-C significantly increased in the Chinese wild rice group. Moreover, Chinese wild rice group had lower contents of serum hs-CRP and TNF-? than those in high lipid group and white rice-flour group, but no effect on serum IL-6. Conclusion Chinese wild rice could improve lipid metabolism and low-grade inflammation of hyperlipidemic rats induced by high lipid diet.

Objective To investigate the effect of kinesio taping on upper crossed syndrome (UCS). Methods From December, 2016 to March, 2017, 52 patients with UCS were randomly divided into control group (n=26) and observation group (n=26). The control group re-ceived exercise therapy, and the observation group received kinesio taping in addition, for four weeks. They were assessed with Visual Ana-logue Scale (VAS), forward head angle (FHA) and forward shoulder angle (FSA). Results There was no significant difference in the score of VAS, FHA and FSA between two groups before treatment (P>0.05). After treatment, the scores of VAS, FHA and FSA significantly de-creased (t>2.804, P<0.05), and they were less in the observation group than in the control group (t>2.632, P<0.05). Conclusion Exercise therapy could relieve pain and correct abnormal posture of UCS, which is more effective combined with kinesio taping.

In order to study the expressions of vascular endothelial growth factor (VEGF) and cyclooxygenase-2 (COX-2) in human laryngeal squamous cell carcinoma (LSCC) and its significance, the expression of VEGF mRNA and COX-2 mRNA in 62 cases of LSCC and 54 adjacent noncancerous laryngeal tissues and 9 normal human laryngeal mucous tissues was detected by using techniques of semi-quantitative RT-PCR. It was found that the expression level of VEGF and COX-2 mRNA was significantly increased in LSCC as compared with that in the normal human laryngeal mucous tissues (both P < 0.01), and the expression level of VEGF and COX-2 mRNA were significantly increased in stage Ill + IV tissues of LSCC as compared with the stage I + II tissues of LSCC (P < 0.01). There was a high positive correlation between VEGF and COX-2 expression in LSCC (r = 0.756, P < 0.01). These data raise the possibility that VEGF and COX-2 may play key roles in the growth, invasion and metastasis of LSCC.
