Objective To observe the hypoglycemic, hypolipidemic and antioxidant effects of Zhuye Shigao Decoction (ZSD) on experimental type 2 diabetes mellitus rats. Methods Type 2 diabetes mellitus rat model was induced by intragastric administration of high fat diet(10 mL/kg) and intraperitoneal administration of streptozotocin (30 mg·kg-1). Sixty male Sprague-Dawley rats were randomized into normal group, model group, low-, moderate-and high-dose ZSD groups (in the dosage of 3.6, 7.2, 14.4 g·kg-1·d-1 respectively), and Metformin group (0.15 g·kg-1·d-1) , 10 rats in each group. With fasting blood glucose, urine glucose, glycosylated hemoglobin, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol(LDL-C), serum insulin, serum superoxide dismutase(SOD) and malondialdehyde (MDA) as the main indexes, we evaluated the influence of ZSD on the blood glucose and lipid levels as well as oxidative stress in type 2 diabetes mellitus rats. Results Compared with the model group, the levels of blood glucose, urine glucose and glycosylated hemoglobin, and the contents of TC, TG, MDA were decreased (P <0.05), whereas SOD activity and serum insulin level were obviously increased (P < 0.05) in ZSD groups. ZSD showed dose-related effectiveness in the treatment of diabetic rats. Conclusion ZSD has certain hypoglycemic, hypolipidemic and antioxidant effects in treating type 2 diabetes mellitus.

Pancreatic cancer has a strong ability of invasive and metastasis,and the mechanism is still not completely clear.It has been demonstrated that aberrant expression of microRNAs(miRNA) is closely associated with the occurrence,development and metastasis of pancreatic cancer.The reveal of miRNA mechanism related to the metastasis of pancreatic cancer would provide a new approach to the treatment of pancreatic cancer.

Objective To analyze the risk factors for traumatic cerebral venous sinus occlusion (CVSO)and to investigate the strategies of early diagnosis of traumatic CVSO. Methods The clinical data of 212 patients with moderate to severe closed traumatic brain injury from January 2012 to December 2015 were analyzed retrospectively. Logistic regression analysis was used to evaluate the risk factors for traumatic CVSO. Results Of the 212 patients with traumatic brain injury, 16.5%(35/212) patients had CVSO. Ten patients had CVSO of thrombotic type (typeⅠ), 16 patients had CVSO of compression type (typeⅡ), and 9 patients had CVSO of mixed type (typeⅢ). Logistic regression analysis showed that skull fracture (OR = 8.141; 95%CI: 3.224-20.840) and epidural hematoma of crossing venous sinus (OR = 3.179; 95%CI: 1.470-7.037) were the risk factors for CVSO, and the former was more significantly correlated with CVSO. Female gender was the risk factor for CVSO typeⅠ(OR =10.425; 95%CI: 1.831-30.053), epidural hematoma of crossing venous sinus was the risk factor for CVSO typeⅡ(OR = 5.766; 95%CI: 1.885-18.197), and skull fracture, epidural hematoma of crossing venous sinus, and the previous history of vein thrombosis was the risk factors for CVSO type Ⅲ(OR =18.005, 4.596, 11.394; 95%CI: 2.021-58.836, 1.144-19.525, 1.436-46.558). Conclusions In the early diagnosis of traumatic CVSO, the crossing venous sinus fracture line and epidural hematoma should be given attention. Attention should be paid to the history of venous thrombosis. MR venography and CT venography contributes to early diagnosis of CVSO.

Objective To evaluate the safety of CT guided percutaneous lung biopsy in the elderly,and to analyze the risk factors for its complications.Methods Totally 204 elderly patients aged ≥65 years underwent transthoracic needle biopsy under CT guidance.Clinical data,complication and its risk factors were analyzed retrospectively.Results The complications included pneumothorax accounting for 15.2％ (31/204),hemoptysis 21.6％ (44/204),and no mortality was found.Logistic regression analysis showed that needle path ≥5.00 cm,lesion size ≤2.00 cm and emphysema around the lesion were the independent risk factors for postoperative pneumothorax (OR=4.05,2.54 and 3.97,all P＜0.05).Meanwhile,the enhancement degree by CT ＞40 HU,needle path ≥5.00 cm and lesion size ≤2.00 cm were the independent risk factors for postoperative bleeding (OR=2.27,2.82 and 2.33,all P＜0.05) in elderly patients undergoing lung biopsy.The sensitivity and specificity for postoperative pneumothorax and bleeding obtained by forecasting equation were 87.1％ and 49.1％,54.5％ and 80.8％ respectively.Conclusions The length of needle path,lesion size and emphysema around the lesion are correlated with pneumothroax,and length of needle path,lesion size and the CT enhancement degree are correlated with bleeding after percutaneous lung biopsy in the elderly.

Objective To investigate the survival, differentiation and action of neural stem cell transplanted into striatum of Parkinson disease rat model. Methods Neural stem cells were isolated and cultured. The character of self-renewing was confirmed by technique of single cell clone culture. The ability of multi-directional differentiation and specific antigen-nestin was showed by immunocytochemistry(ICC). PD rat models were established, and the DAPI-labelled neural stem cells were transplanted into striatum. The 6-HHDA induced rotary behavior was measured, distribution and migration of the cell were checked by fluoresce activating. ICC and HPLC are used to see its differentiation and action of secrete neurotransmitter dopamine(DA) and it’s metabolites. Results The cultured stem cell express nestin and have the ability of self-renewing and multi-directional differentiation. 6-HHDA induced rotation decreased after transplantation of NSC into the PD rat striatum(P

Objective:To evaluate the effect of high intensity interval training on cancer patients.Methods:Web of Science, EBSCO, PubMed, Ovid, EMbase, Cochrane Library, CBM, CNKI and Wanfang database were searched for randomized controlled trials of the effect of high intensity interval training on cancer patients, RevMan5.3 software was used for analysis.Results:Eleven articles with a population of 614 were included in the analysis, which involved 323 cases of the intervention group and 291 cases of the control group. The analysis showed that high intensity interval training could improve the total quality of life ( SMD values were 0.40, 95% CI 0.14-0.65, P<0.01) and peak oxygen uptake ( MD values were 3.00, 95% CI 2.19-3.80, P<0.01) of cancer patients, and reduce carotid intima-media thickness ( MD values were -0.06, 95% CI-0.08--0.03, P<0.01), but did not reduce the high-sensitivity C-reactive protein ( MD values were -0.61, 95% CI-1.23-0.01, P>0.05) and body weight ( MD values were 0.16, 95% CI-3.19-3.51, P>0.05). Conclusions:High intensity interval training has a positive impact on quality of life, cardiopulmonary function and carotid intima-media thickness with cancer patients, but has no significant effects on high-sensitivity C-reactive protein and body weight.

AIM: To explore the effect and the mechanism of sulphated heparin on the proliferation and the apoptosis of human hepatocellular carcinoma cells. METHODS: The human hepatocellular carcinoma cell line (HepG-2) was used to identify the expression of ras gene protein and to study the effect of sulphated heparin on proliferation and the apoptosis in vitro . RESULTS: The sulphated heparin downregulated the ras protein expression and inhibited the cell growth in HepG2 cells. In the presence of sulphated heparin, the apoptosis rate of HepG2 increased. CONCLUSION:The data suggest that the effects of sulphated heparin on the proliferation and the apoptosis of the human hepatocellular carcinoma cell are correlated with the signaling transduction mediated by ras gene protein.

Objective To explore the clinical manifestations and the characteristics of images of indocyanine green angiography (ICGA) and fundus fluorescein angiography(FFA) of multifocal choroiditis. Methods Eight patients (10 eyes) with multifocal choroiditis were gathered. The clinical manifestations and the images of ICGA and FFA were analyzed. Results Foci of multifocal choroiditis were found in posterior pole and peripheral areas of ocular fundi of all of the 10 eyes. The images of ICGA revealed hypofluorescence in focal area. The images of FFA showed hypofluorescence at the early phase and fluorescein leakage at the late phase in the active focus, and fluorescein staining and window defect fluorescence in the inactive focus. Conclusions The clinical manifestations of multifocal choroiditis varied with disease course, location and numbers of the lesions. ICGA and FFA can show the development of the disease clearly, which may guide the treatment.

The event-related desynchronization/synchronization(ERD/ERS) time courses of lower and upper alpha band rhythms during hand motor imagery are investigated respectively by Fourier Sectral Entropy (FSE) in this paper. By analyzing one group of BCI competition data, it was found that FSE within upper alpha band displays a pronounced increase and decrease over contralateral and ipsilaterai brain areas respectively at the onset of hand motor imagery, which is corresponding to the antagonistic ERD/ERS patterns in previous studies. Different from the upper alpha activity pattern, FSE within lower alpha band displays a consistent increase over both two hemispheres hand representative areas. The preliminary results show that FSE could disclose the different behaviors of the upper and lower alpha band rhythms so that a new idea with the complexity measure is provided to characterize functional dissociation of lower and upper frequency alpha rhythms in relation to hand motor imagery.
