The quality of traditional Chinese medicines (TCMs) has been mainly evaluated based on chemical ingredients, yet recently more attentions have been paid on biological ingredients, especially for pill-based preparations. It is a key approach to establish a fast, accurate and systematic method of biological ingredient analysis for realization of modernization, industrialization and internationalization of TCMs. The biological ingredient analysis of TCM preparations could be abstracted as the identification of multiple species from a biological mixture. The metagenomic approach based on high-throughput-sequencing (HTS) and big-data-mining has been considered as one of the most effective methods for multiple species analysis of a biological mixture, which would also be helpful for the analysis of biological ingredients in TCMs. Simultaneous identification of diverse species, including the prescribed species, adulterants, toxic species, protected species and even the biological impurities introduced through production process, could be achieved by selecting appropriate DNA biomarkers, as well as applying large-scale sequence comparison and data mining. By this approach, it is prospective to offer an evaluation basis for the effectiveness, safety and legality of TCM preparations.

This paper introduces the perioperative nursing of 83 sialolithiasis patients undergoing sialolithectomy by sialoendoscope. The key points of successful nursing care were careful preoperative psychological nursing and equipment preparation, correct and skilled intraoperative cooperation, and early postoperative health instruction. As a result, all the patients underwent the surgery succesfully and recovered well except 3 cases who needed gland removal later.

Objective to evaluate the clinical efficacy and safety of ADSCs infusion in patients with type 2 diabetes mellitus(t2DM). Methods Autologous ADSCs were cultured and identified. totally 48 cases of type 2 diabetes patients were divided into two groups:24 cases in A group re-ceived ADSCs and conventional treatment,while the other 24 cases in B group received conventional treatment. With 15 months′follow-up,FPG,2h-PGh,HbA1c,FC-P,AUCC,insulin medication changes and security on post-treatment 3,6,12 and 15 months were calculated. Results the AD-SCs which cultured met the clinical application of standards. FPG,2h-PGh and HbA1c in both groups were significantly decreased,and the values in A group were more impressive than B. there were significant improvement in FC-P,AUCC and insulin of A group compared with B group. there was not treatment related adverse events. Conclusion the clinical data demonstrate that the treatment with ADSCs can improve metabolic control and beta cell function in patients with t2DM. Moreover,the safety of the treatment method was considerable.

Objective To research the expression of mitofusin-2 (mfn2) and tumor metastasis suppressor genes (nm23)in bladder cancer cells and its correlation with clinical pathological feature. Methods Immunohistochemistry was used to measure the expression of mfn2 and nm23.Sixty-five cases of bladder cancer were sampled,which include fif-ty cases of male and fifteen cases of female. TNM stage:Forty-seven cases were in stage I;Ten cases were in stage II; Five cases were in stageⅢ; Three cases were in stageⅣ. Other fifteen cases were sampled from normal bladder or benign tumor of bladder as control . All cases were collected from department of pathology,affiliated Hospital of hebei union university. Results The positive expression rate of mfn2 in bladder cancer tissues was significantly higher than those in normal blad-der tissues and benign tumor of bladder(χ2=32.528,P<0.05);The positive expression rate of nm23 in bladder cancer tis-sues was significantly lower than those in normal bladder tissues and benign tumor of bladder (χ2=19.719,P<0.05);the high expression level of mfn2 in bladder cancer was associated with tumor differentiation and TNM stage(P<0.05),but not corre-lated with age,sex,lymph node metastasis and clinical grade. The low level of nm23 was associated with TNM stage,clinical grade and LN metastasis. Conclusion The positive expression rate of mfn2 was increased in bladder cancer. It indicated that there was a close relationship between mfn2 and the occurrence and development of bladder cancer;The expression rate of nm23 was decreased in bladder cancer,it may be a predictor for metastasis and prognosis of bladder cancer.

AIM: To investigate the effect of GSTP1 over-expression on the sensitivity of human hepatoma HepG2 cells to oxaliplatin (OXA).METHODS: Adenovirus carrying GSTP1 (Ad-GSTP1) was used to infect HepG2 cells for establishing the cell line over-expressing GSTP1.The cells were randomly divided into 6 groups: control, vehicle, Ad-GSTP1, OXA, OXA +vehicle and OXA +Ad-GSTP1.The cell survival rates were examined by CCK-8 assay, and the apoptotic rates were analyzed by flow cytometry.The protein levels of GSTP1, Akt, mTOR, p-Akt and p-mTOR were deter-mined by Western blot.RESULTS: OXA decreased the cell survival rate in a dose-dependent manner (P <0.05).The protein expression of GSTP1 increased after transfection with adenovirus.At basal level, up-regulation of GSTP1 signifi-cantly decreased the cell survival rate, increased the cell apoptosis, and inhibited the phosphorylation levels of Akt and mTOR (P <0.05).Moreover, GSTP1 over-expression enhanced the effect of OXA on the cell viability, cell apoptosis, and further inhibited the phosphorylation levels of Akt and mTOR ( P <0.05).CONCLUSION: Over-expression of GSTP1 augments the enhanced effect of OXA on HepG2 cell apoptosis, which may be related to the inactivation of Akt/mTOR signaling pathway.
