So far, the major therapeutic drugs of diabetes are western medicine , but side effects of hypoglycemic western med-icine are large and not easy to take for a long time .In recent years , we found the side effects of some kind of hypoglycemic Chinese herbal medicine were small , much easier to be accepted by the patients .Thus, the clinical treatment of diabetes may have new meth-ods.According to the mechanisms of Traditional Chinese Medicine for protection of islet function , this review will discuss them from re-ducing oxidative stress , increasing the number of islet cells and promoting βcells to secrete, relieving insulin resistance , increasing in-sulin sensitivity and so on .All of these aspects reflect the unique role of Traditional Chinese Medicine in the treatment of diabetes and protection of islet function .

Objective To explore the effect of microRNAs 224 and 21 on human glioma stem cells survival and the possible molecular mechanisms.Methods qPCR was used to detect the dysregulated expression of microRNAs in malignant glioma samples, human GBM stem cells, artificially established GBM stem cell lines and human tissues.Caspase 3/7 assay, Annexin V apoptosis/fluorescence assay were performed to determine the effect of miR-21 or miR-224 mimics and inhibitor on cell apoptosis.Living cells count was used to assess miR-21 or miR-224 mimics and inhibitor on cell growth.TargetScan was used to explore potential targets of miR-21 and miR-224, and dual luciferase reporter assay was used to identify whether the 3’UTR of Caspase 3, Caspase 9 and Bim mRNA was a binding target of miR-21 or miR-224.Western blot was used to detect the expression of Caspase 3, Caspase 9 and Bim protein after transfection of miR-21 or miR-224 mimics or inhibitors.Results miR-21 and miR-224 are strongly upregulated in GSC samples, multiple GBM human tumor specimens, and GBM neurosphere stem cell lines ( P<0.05 ) .Caspase 3/7 assay and Annexin V apoptosis/fluorescence assay results showed that miR-224 and miR-21 regulated GSC apoptosis.Living cells count results demonstrated that miR-224 and miR-21 regulated GSC growth.miR-224 and miR-21 regulate pro-apoptotic gene expression by directly targeting Caspase 3, Caspase 9, and Bim 3’-UTRs. Conclusion These results indicate that miR-224 and miR-21 are important physiologic drivers of GSC resistance to apoptosis, providing new points of therapeutic leverage against these treatment-resistant cells.

Methoxyadiantifoline ( MAF) is a new alkloid isolated from Thalictrum Omeience W.T.Wang.During 3 min reperfusion after 10 min of coronary ligation, MAF 5 ?mol/L significantly decreased the incidence of isolated rat hearts with ventricular arrhythmias ( VF and VT ) . It delayed the onset of ventricular fibrillation and shortened its duration and markedly prolonged the time of normal sinus rhythm. It also significantly decreased the release of LDH from the myocardium in isolated rat hearts. In addition , MAF 5 ?mol/L could decrease the heart rate and coronary resistance. The results suggest that MAF possessed protective effects on the reperfusion injury in isolated rat hearts.

Objective:To investigate the effect of short-term intensive treatment with insulin on metabolic control,?-cell function and insulin resistance in newly diagnosed type 2 diabetic patients. Methods:Thirty-eight newly diagnosed type 2 diabetic patients were randomly divided into two groups and treated with continuous subcutaneous insulin infusion(CSII) or multiple daily insulin injection(MDI) for 1 month.Fasting blood glucose(FBG) and lipid profiles were measured,and oral glucose tolerance test(OGTT)was performed before and after the treatment.The second phase insulin and C peptide secretions were measured by calculating area under curve(AUC) in OGTT.HOMA model was used to evaluate ?-cell function((HOMA-?)) and insulin resistance. Results:Excellent control of FBG was achieved after 1 month intensive treatment.(HOMA-?) was improved significantly. Conclusion:The excellent metabolic control and ?-cell function improvement can be achieved by short-term intensive insulin therapies like CSII or MDI.

Background and purpose:The American College of Surgeons Oncology Group (ACOSOG) Z0011 trial has been described as practice-changing of sentinel lymph node (SLN) positive breast cancers. The goal of this study was to determine the exportability of the criteria deifned by Z0011 trial for selecting patients who are eligible for avoiding axillary lymph node dissection (ALND) after a positive sentinel lymph node biopsy (SLNB) result in China.Methods:We collected 194 breast cancer patients with positive SLNs and classiifed them into two groups according to Z0011 criteria. One group was consisted of patients who were eligible for omitting ALND and with SLNB only. The other one was ALND group. Then the patients of SLNB group were compared with cohort included in the Z0011 trial and the ALND group of this study separately.Results:Seventy-seven patients were potentially eligible for omitting ALND and 117 patients were still needed to have ALND. Compared with Z0011 cohort, the SLNB group in this research had signiifcantly more T1 stage and ER positive tumors (P<0.05). More patients in SLNB group had positive LNs with the number less than 3 and negative NSLNs (P<0.05). The ALND group had more T2 and T3 stage tumors than the SLNB group but the difference was not signiifcantly. The number of positive LNs in ALND group was higher than the SLNB group signiifcantly (P<0.05). More patients in the ALND group had positive non-sentinel lymph node (NSLN) than the SLNB group and the difference was also signiifcantly (P<0.05).Conclusion:Applied to the SLN positive patients in this study, Z0011 criteria could make patients with better prognosis and lower risk than Z0011 cohort be selected and let these patients avoiding ALND more safely.

Objective To explore the diagnostic value of combined detection of the liquid array technology, interfer-on (IFN)-γand IFN-γ-inducible protein (IP)-10 in the rapid, accurate diagnosis and differential diagnosis of tuberculous pleural effusions. Methods Patients with transudative pleural effusions were divided into tuberculous pleural effusion group (n=52) and malignant pleural effusion group (n=38). The method of T-SPOT.TB was used to detect the number of effec-tor T cells sensitized to Mycobacterium tuberculosis and spot forming cells (SFCs). The liquid array technology was used to detect the level of IFN-γand IP-10. Logistic regression was used to analyze and compare the diagnostic value of the two-method combination. Results The diagnostic sensitivity, specificity and the area under the ROC curve (AUC) of T-SPOT. TB were 90.38%, 84.21%, and 0.938 (95%CI:0.867-0.978), respectively. The diagnostic sensitivity, specificity and AUC of combined detection of IFN-γand IP-10 were 98.08%, 97.37%, and 0.995 (95%CI:0.951-1.000), respectively. There was no significant difference in the diagnostic sensitivity and specificity between the two methods, and the diagnostic agreement for the two diagnostic methods was fine (Kappa=0.703). The difference of AUC between the methods was significantly differ-ent (Z=1.996, P<0.05). The method of combined detection of IFN-γand IP-10 showed the larger AUC (AUC=0.995). Con-clusion The combined diagnosis meets the clinical needs of rapid, accurate diagnosis and differential diagnosis for tuber-culous pleural effusion by simultaneously assaying the level of IFN-γand IP-10 using the liquid array technology.

Objective To explore a rapid and accurate method for the diagnosis of smear negative tuberculosis meningitis (TBM). Methods Sixty-seven patients with TBM were selected from Tianjin Haihe Hospital from June 2014 to June 2016, and 118 patients with non-tuberculous meningitis (NTBM) in the same period were chosen as control group, including bacterial meningitis (BM) group (n=61) and viral meningitis (VM) group (n=57). The laboratory routine, biochemical and immune indicators were tested with the specimens of both the blood and cerebrospinal fluid of all the patients. The Logistic regression equation was established for the diagnosis of TBM, and the diagnostic efficacy of which was evaluated by the receiver operating characteristic curve (ROC). Results The predictive regression equations of the TBM with BM, VM and NTBM (BM + VM) were obtained when BM group was used as a control: PRE_BM=1/1 +e-(-5.298+0.196 × ESAT-6+ 0.119 × CFP-10-2.968 × PCT+2.206 × ADA_CSF+0.705 × GLU_CSF+0.093 × LDH_CSF), PRE_VM=1/1+e-(-6.907+0.394 × ESAT-6-0.120 × Na+2.633 × ADA_CSF-0.088 × Cl_CSF) and PRE_NTBM=1/1+e-(0.683+0.099×ESAT-6+0.063×CFP-10-2.645×PCT+1.393×ADA_CSF+1.342×TbAb_CSF)respectively. When BM group was served as a control, the sensitivity, specificity, positive and negative predictive values of the regression for the diagnosis of TBM were 97.01%(89.63%-99.64%), 98.36%(91.20%-99.96%), 98.48%(91.84%-99.96%) and 96.77%(88.83%-99.61%), respectively.When VM group was served as a control, which were 94.03%(85.41%-98.35%), 94.74%(85.38%-98.90%), 95.45%(87.29%-99.05%) and 93.10%(83.27%-98.09%), respectively. When NTBM group was served as control, which were 94.03%(85.41%~98.35%), 90.68%(83.93%-95.25%), 85.14%(74.96%-92.34%) and 96.40%(91.03%-99.01%), respectively. Conclusion The predictive regression equation could be used as early diagnostic TBM with high sensitivity and specificity, which should be popularized in clinical practice, while, according to the higher negative predictive value, the negative results of which could be used to rule out of the TBM and non-empirical medication.
