Objective To explore the effects of high glucose on glucose transport activity, and phosphorylationandexpressionofinsulinsignalingproteins in primary cultured rat adipocytes. Methods Isolated rat adipocytes were cultured at different glucose concentrations (5, 10, 15, 25 mmol/L) for 24 h. Then the glucose uptake, the phosphorylations of insulin receptor (IR), insulin receptor substrate (IRS) 1 and 2 and protein kinase B (PKB) as well as the protein expressions of IRS1, IRS2, p85 subunit of phosphatitylinositol 3 kinase (p85) and PKB were measured. Results These adipocytes treated with different high glucose showed the impairment of the basal and insulin induced increase in glucose uptake and significant decrease of IR, IRS1 and PKB phosphorylations as well as IRS1 protein expression, but up regulation of IRS2 protein expression. p85 and PKB contents and IRS2 phosphorylation were unaffected. Conclusion The exposure to high glucose inhibits glucose uptake and induces insulin resistance in adipocyte. The mechanism may be involved in affecting the multiple step phosphorylations and the expressions of insulin signaling proteins.

0.05).②The animal experiment showed ,in contrast to the control , embryonate rats’ rhodocyte SOD were significantly different after 2 days but no difference before prenatal. ③in contrast with the control , SOD of placenta were significantly different only after 9 days. Conclusions Diagnostic ultrasound in early pregnancy can make SOD change ,but the changes can be reparable.

Objective:To explore the therapeutic effect of Chinese herbal medicine for prevention and treatment of acute radiation oropharyngeal inflammation of nasopharyngeal carcinoma.Methods:120 cases of nasopharyngeal carcinoma were randomly divided into an experiment group of 60 cases treated with Chinese herbal medicine and a control group of 60 cases with gargling of Dobell's solution.The incidence rate and the extent of radiation oropharyngeal inflammation,total therapeutic time and short-term therapeutic effect in both groups were investigated.Results:There was no oropharyngeal inflammation of grade 0 in both groups. The incidence rate of radiation oropharyngeal inflammation in the experiment group was significantly lower and the effective rate was significantly higher than those in the control group(P0.05).Conclusion:Chinese herbal medicine combined with radiotherapy can relieve acute radiotherapy oropharyngeal inflammation in the patient of nasopharyngeal carcinoma with no significant adverse reaction and do not influence the short-term therapeutic effect.

Objective:To establish the quality standards for Zhichuan adhesive plasters;Methods:Herba ephedrae、Bergenin arolisiae、Flos caryophylli、Semen sinapis in Zhichuan adhesive plasters were identified by TLC. Ephedrine hydrachloride in Herba ephedrea was determined by RP HPLC.Results:These methods were simple and accurate.Conclusion: The methods can be used for the quality control of Zhichuan adhesive plasters.

Objective　To evaluate the effects of vitrectomy associated with extraction of intraocular foreign bodies in the posterior segment.Methods　Retrospective analysis was done on clinical records of 11 patients (11 eyes) having undergone vitrectomy company with extraction of intraocular foreign bodies in the posterior segment.Results　The intraocular foreign bodies in the posterior segment were extracted successfully in all cases, the retinal detachment and endophthalmitis were cured. Postoperation visual acuity was improved in 8 eyes and did not change in 3 eyes. None suffered from postoperative secondary intraocular hemorrahge, decompensation of corneal endothelium and other serious complications.Conclusion　Vitrectomy combined with extraction of intraocular foreign bodies in the posterior segment is less damaging, accurate and safe, and enhances the cure rate. It is an effective method for treating intraocular foreign bodies.

Objective To analyze the clinical application value of endometrial collector combined with liquid based cytology and histological examination for screening of endometrial cancer.Methods One hundred and eighty-two cases high-risk people with endometrial cancer in Songgang People's Hospital of Bao'an district of Shenzhen from June 2014 to December 2015 were collected,among them 71 patients with endometrial cancer were found in the patients who were diagnosed by pathological diagnosis,and the remaining 111 were not diagnosed with endometrial cancer.The material satisfaction,sample collection time of sample collection and endometrial curettage device were comparatively analyzed and also the cervical dilatation production rate,the amount of bleeding,pain score(VAS) were analyzed.The application value of endometrial collector combined with liquid based cytology and histological examination for screening of endometrial cancer was judged according to the results obtained.Results There was no significant difference between the two methods based on satisfaction(χ2=1.953,P=0.089).A methods of cervical endometrial expansion rate(3.85% vs.93.96%) and acquisition time((16.35±2.19) min vs.(11.23±4.26) min),bleeding volume((1.64±0.63) ml vs.(15.73±5.41) ml),VAS score((0.82±0.24) points vs.(4.34±2.43) points) were significantly lower than that of curettage sample collection method(χ2=16.473,P=0.000;t=5.733,P=0.034;t=11.183,P=0.000;t=3.618,P=0.043).With curettage pathological diagnosis as the gold standard,the specificity,sensitivity and diagnostic coincidence rate of endometrial biopsy combined with liquid based cytology and histological examination for screening endometrial carcinoma were respectively 94.51%,95.05% and 94.96%.Conclusion Compared with curettage sampling method,endometrial curettage collector has features of high success rate,short time,low pain and high security and the cervical dilation rate is low.Endometrial curettage collector can be combined with liquid based cytology and histology to examine and screen endometrial cancer.This methods is worth promoting.

Objective:To investigate the feature of depression in patients with Parkinson's disease(PD) and the related factors.Methods:Use Hamilton Depression Scale(HAMD) to measure the level of depression of 60 patients with PD.Functional state of the patients was evaluated by Motor Dysfunction Rating Scale for Parkinson's Disease(MDRSPD).Results:29 cases(48.3%) were identified to have depression,among whom 40% were of minor or moderate degree,8.3% were severe.The main manifestations of depression were anxiety/body,retardation,hopelessness and insomnia.Scores of hopelessness,retardation,and insomnia factor were significantly higher in the rigidity and tremor combining rigidity patients than those in tremor patients.The level of depression positively correlated with the duration of disease and degree of dysfunction due to PD,and it has no relation with age,sex,and education.Conclusions:The incidence of depression was higher in patients with PD.PD patients of different clinical types had different characteristics of depression.The rigidity type is more likely to get depression.The degrees are closely related to duration of disease and degree of dysfunetion.

Objective To study the effects of puerarin on advanced glycation end products (AGEs) and expression of monocyte chemoattractant protein-1 (MCP-1) in diabetic rats. Methods The rats were randomly divided into normal control rats (CON rats), diabetic rats (DM rats), diabetic rats treated with aminoguanidine (AG rats), and diabetic rats treated with puerarin (PU rats). The diabetic rat model was induced by streptozotocin. The serum levels of AGEs and MCP-1 were quantified by fluorescence spectroscopy and ELISA respectively. Tissue sections with PAS staining and electronic microscopy were used for observation of the pathologic changes in renal tissues. Immunohistochemistry was applied to detect the expression of MCP-1 protein in renal cortex. Results Serum levels of AGEs and MCP-1 in DM rats were higher than those in PU rats and AG rats (both P
