Objective To observe the clinical efficacy of ZHU Lian's acupuncture-activatingmethod in treating deglutition disorder due to pseudobulbar palsy after cerebral stroke.Method Sixty patients with deglutition disorder due to pseudobulbar palsy after cerebral stroke in acute stage were randomized into an observation group and a control group, 30 cases in each group. The two groups both received symptomatic neurological treatment. In the two groups, acupoints including Lianquan (CV23), Huiyan (Extra), Baihui (GV20), and bilateral Shuaigu (GB8), Wangu (GB12), Zhaohai (KI6), Lieque (LU7),and Yinlingquan (SP9) were selected. The observation group was intervened by ZHU Lian's acupuncture-activating method; the control group was intervened by ordinary needling method plus G6805 therapeutic appliance with sparse-dense wave for 20 min. Prior tothe treatment and after 10 treatment courses, the two groups were evaluated by using Videofluoroscopic Swallowing Study (VFSS) and Kubota's water drinking test for swallowing function.Result After 10 treatment courses, the total effective rate was 96.7%in the observation group versus 83.3% in the control group, and the between-group difference was statistically significant (P<0.05); the VFSS score in the observation group was significantly different from that in the control group (P<0.01); the water drinking test score in the observation group was significantly different from that in the control group (P<0.01). The results indicated that the therapeutic efficacy was more significant in the observation group compared to that in the control group.Conclusion ZHU Lian's acupuncture-activating method can produce a more significant efficacy in treating deglutition disorder due to pseudobulbar palsy after cerebral stroke in acute stage compared with sparse-dense-wave electroacupuncture.

Objective To explore the effect of QizhiJiangtang Capsule on the insulin resistance (IR)in the diabetic rats,and to clarify the action mechanism.Methods The diabetes rat models were induced by high fat diet combined with STZ injection.The successful models of the rats were randomly divided into diabetes group (DM), ShenqiJiangtang Granule group (SQ)and high (QJH),middle-(QJM),low (QJL)doses of QizhiJiangtang Capsule groups;at the same time control group (NC)was established. The drug concentrations in high, middle and low-doses of QizhiJiangtang Capsules groups were 1.35, 0.68, and 0.34 g · kg-1 respectively;and the concentration of ShenqiJiangtang Granule was 0.27 g·kg-1.After the diabetic model was established successfully, the rats were treated for 8 weeks on the basis of drug dose.Then the levels of fasting blood glucose (FBG),fasting insulin (FINS),insulin resistance index (IRI)and biochemical indexes related to lipid metabolism of the rats were measured using blood glucose detector and automatic biochemistry analyser.The gene expression of insulin receptor substrate-1 (IRS-1),phosphatidyl inositol 3-kinase (PI3K),and glucose transporter 4 (GLUT4)in liver tissue were examined by Real Time PCR.The levels of tumor necrosis factorα(TNF-α)and adiponectin (ADPN)in serum were detected using ELISA.Results Compared with control group,the levels of FBG,FINS and IRI of the rats in diabetes group were significantly increased (P<0.05 or P<0.01 );the serum total cholesterol (TC), triglyceride (TG)and low density lipoprotein (LDL)levels were significantly increased (P<0.05 ), while the serum high-density lipoprotein (HDL)level was significantly decreased (P<0.05);the mRNA expression levels of IRS-1,PI3K and GLUT4 in liver tissue were decreased (P<0.05);the level of serum TNF-αwas increased (P<0.05),but the ADPN level was decreased (P<0.05).Compared with diabetes group,the FBG level and IRI of the rats in QizhiJiangtang Capsule and ShenqiJiangtang Granule groups were significantly decreased (P<0.01);the levels of FINS of the rats middle and high doses of in QizhiJiangtang Capsule groups and ShenqiJiangtang Granule group were significantly decreased (P<0.05);the levels of serum TC,TG and LDL of the rats in middle dose of QizhiJiangtang Capsule group and ShenqiJiangtang Granule group were significantly decreased (P<0.05 or P<0.01),but the HDL level was increased (P<0.05);the mRBA expression lvels of IRS-1,PI3K and GLUT4 inliver tissue were increased (P<0.05);the levels of serum TNF-αof the rats in middle dose of QizhiJiangtang Capsule group and Shenqijiangtang Granule group were significantly decreased (P<0.05),but the serum ADPN levels were increased (P<0.05 ). Conclusion QizhiJiangtang Capsule can significantly improve the IR in the diabetic rats,and the pharmacological mechanisms are related to adapting the blood lipid component and insulin signal transduction pathways.

Objective:To treat the chronic non-atrophic gastritis patients induced by Helicobacter pylori with Qingweizhitong Weiwan combined with standard triple therapy,and to detect the differential expression of related immflammation genes with PCR array,and to clarify its mechanism.Methods: Ten patients with chronic non-atrophic gastritis complicated with Helicobacter pylori infection were used as treatment group and 10 health people were used as health control group. The patients in treatment group were treated with Qingweizhitong Weiwan combined with standard triple therapy for 14 d. The blood samples of the subjects in treatment group and health control group were collected before and after treatment,and QIAGEN human antibacterial response PCR array was performed to test the total RNA inperipheral blood and to analyze the differential expressions of 84 inflammation-related genes.Results:The differential expressions of 20 inflammation-related genes were found.Compared with health control group,the expression levels of 20 genes in treatment group before treatment were up-regulated (Fold-change>2);after treatment,the expression levels of 20 genes were down-regulated,and 11 of them were similar to the level in health control group (Fold-change< 2).More specifically,part of 20 genes was related to NLRP3 inflammasome.Compared with health control group,the gene expression levels of CASP1,IL1B,NLRP3,and PYCARD in treatment group before treatment were up-regulated (P <0.05).Compared with before treatment,the expression levels of CASP1,IL1B,NLRP3,and PYCARD in treatment group after treatment were down-regulated (P <0.05).Conclusion:The mechanism of Qingweizhitong Weiwan combined with standard triple therapy in the treatment of chronic non-atrophic gastritis patients induced by Helicobacter pylori may be related to inhibiting the expressions of NLRP3 inflammasome-related genes and interfering the antimicrobial innate immune response.

Objective : To explore the type and control measure of black dot⁃like contaminants in cell cultures. Methods: The growth state of bacteria was investigated under an inverted microscope ; Their morphological characteristics were analyzed by Gram and auramine O staining as well as electron microscopy; 16S rDNA gene sequencing was used to analyze bacterial species ; Drug sensitivity test was used to screen antibiotics against the bacteria;Cryopreserved SH⁃SY5Y cells were resuscitated by cell culture supernatant of RAW264 cells. Results: Inverted microscopic real⁃time observations showed that black dot⁃like substances had two growth states : static and moving.They were negative for Gram staining while positive for auramine O staining. Electron microscopy revealed that they were short rod⁃shaped bacteria with a polar flagellum during moving phase. 16S rDNA gene sequencing showed that these bacteria were phenylobacterium zucineum HLK1. Ceftriaxone , carboxycillin and imipenem were screened by drug sensitivity test to have inhibitory effects on the bacteria , but cell culture experiments showed that they could not remove the bacteria from SH⁃SY5Y cells. Contaminated cells could not be cryopreserved for a long time , but resuscitation with RAW264. 7 cell culture supernatant significantly improved the survival rate of cells. Conclusion The black dot⁃like contaminants in cell cultures are a special type of oligotrophic bacterium with strong viability that can invade the cells and cannot be cleared with antibiotic treatment. RAW264. 7 cell culture supernatant seems contain some substances against bacteria , and resuscitating frozen cells with RAW264. 7 cell culture supernatant may significantly improve the survival rate of cells.
