Objective To study the clinical experience and determine the optimal timing for periop-erative internal aortic balloon pumb (IABP) support in high-risk patients who had coronary artery bypass grafting (CABG) had been demonstrated. Methods Fifteen cases of emergency CABG with IABP were performed from September 2003 to April 2008. Eight cases were supported by IABP before operation,1 case was supported after succeeding in cardiopulmonary resuscitation,2 cases were supported by IABP for acute myocardial infarction,5 cases were supported by IABP for acute coronary syndrome. Seven cases were supported by IABP in the time of intra-or postoperation,2 cases were supported by IABP in order to help re-moving cardiopulmonary bypass in the operation. Result Three cases supported by IABP in the time of in-tra-or postoperation were dead, the other 12 cases were healed. Conclusions IABP can improve the heart function effectively and therefore can increased the success rate of operation.The beneficial effect of preoperative IABP in high-risk patients who have CABG is confirmed.

Objective To investigate the relationship of the serum level of IL-23 and MMP-9 with the clinicopathologic features in patients with esophageal squamous cell carcinoma (ESCC). Methods 48 pathologically confirmed ESCC patients and 30 Endoscopic biopsy of benign were included in this study. The serum levels of IL-23 and MMP-9 were examined by enzyme-linked immunosorbent assay (ELISA). Results Serum IL-23 level in patients with ESCC was significantly higher than that in controls (t = 26.66, 16.89, P<0.05). Furthermore, Pearson′s correlation analysis revealed that serum IL-23 was positively correlated with the serum MMP-9 level in ESCC patients (r = 0.790, P < 0.05). Statistical analysis showed that enhanced serum IL-23 significantly correlated with the degree of differentiation and lymph node metastasis. Conclusion Overexpression of IL-23 may involve in the occurrence and development of ESCC. IL-23 may contribute to tumorinvasion and metastasis by stimulating the expression of MMP-9.

Objective: To acquire recombinant nematode anticoagulant peptide ( NAP) with high anticoagulant activity. Methods: Pichia pastoris GS115 strain was transformed with recombinant yeast expression vector pPICS. 5K-rNAP. Expression of rNAP was induced with methanol after the identification of positive strains. NAP expressed in the collected yeast culture supernatant was confirmed with SDS-PAGE and Western blot. The biological activity of the products was validated with PT (prothrombin time) , INR (international normalized ratio) and APTT (activated partial thromboplastin time) , respectively. Results: The yeast strains expressing NAP were identified. The rNAP was secreted into culture supernatant with a molecular weight of about 10 kDa due to glycosylation, which is a little bigger than that predicted (8.7kDa). The anticoagulant efficiency of rNAP was confirmed with the in vitro assays. Conclusion: The recombinant nematode anticoagulant peptide with high biological activity was successfully expressed in Pichia pastoris and can be used in the future development of novel anticoagulant agent.

Objective To explore the risk factors of systemic inflammatory response syndrome crisis (SIRS) after percutaneous nephrolithotomy (PCNL) in China. Methods Databases of CNKI, CBM, WanFan and VIP were searched to retrieve studies about systemic inflammatory response syndrome after percutaneous nephrolithotomy to October, 2016. Results 18 studies involving 5,323 patients were included. The results of meta-analysis showed that:a) univariate analysis indicated that renal insufficiency [O(R) =2.78, 95%CI (1.96 to 3.95), P = 0.000], preoperative positive urine culture [O(R) = 3.41, 95%CI (1.89 to 6.15), P = 0.000], preoperative routine urine leucocyte positive [O(R) = 3.78, 95%CI (3.02 to 4.72), P = 0.000], diabetes mellitus [O(R) = 2.14, 95%CI (1.33 to 3.45), P = 0.002], pelvic positive urine culture [O(R)= 5.14, 95%CI (2.46 to 10.73), P = 0.000] and operation time ≥120 min [O(R) = 2.31, 95%CI (1.40 to 3.82), P = 0.001] were the risk factors of SIRS; b) multivariate analysis showed that, preoperative positive urine culture [O(R) = 6.83, 95%CI (2.82 to 16.57), P = 0.000], preoperative routine urine leucocyte positive [O(R) = 5.43, 95%CI (3.51 to 8.41), P = 0.000], diabetes mellitus [O(R) = 2.85, 95%CI (1.45 to 5.58), P = 0.002], pelvic positive urine culture [O(R) = 4.30, 95%CI (1.30 to 14.21), P = 0.020] and operation time ≥120 min [O(R) = 2.72, 95%CI (1.62 to 4.59), P = 0.000] were the independent risk factors of MCAT. Conclusion The independent risk factors of SIRS for patients after PCNL are diabetes mellitus, preoperative positive urine culture, preoperative routine urine leucocyte positive, pelvic positive urine culture and operation time. However, due to the quantity and low quality of the included literature, the conclusion needs the support from high quality studies.

OBJECTIVETo systematically evaluate the efficacy and safety of kidney-tonifying traditional Chinese medicine in the treatment of male infertility.

METHODSBased on the principles and methods of Cochrane systematic reviews, we searched CNKI, VIP, and Wanfang databases from inception to December 2012 for randomized controlled clinical trials addressing the treatment of male infertility with kidney-tonifying traditional Chinese medicine. According to the inclusion and exclusion criteria and retrieval strategies, we extracted the data, evaluated the quality of the included literature, and conducted meta-analysis using the RevMan 5. 2 software.

RESULTSTwenty trials involving 2,272 patients were included, and the sample size of each study was from 60 to 270 cases. All the studies were graded as of poor quality, with Jadad scores of no more than 3 points. The results of meta-analysis showed that the total effectiveness rate of traditional Chinese medicine versus Western medicine on male infertility was RR = 1.71, 95% CI 1.19-2.47, and that of Chinese-Western combined therapy versus Western medicine was RR = 1.15, 95% CI 1.01-1.30. Both traditional Chinese medicine and Chinese-Western combined therapy showed a significantly better total effectiveness than Western medicine alone in improving the pregnancy rate without serious adverse reactions.

CONCLUSIONDue to the poor methodological quality and high heterogeneity of the included studies, the evidence for the efficacy and safety of kidney-tonifying traditional Chinese drugs in the treatment of male infertility is of but limited value, and further validation is needed by more high-quality studies.

OBJECTIVETo observe the effects of electroacupuncture (EA) on circadian rhythm of temperature and melatonin (MT) in depression rats model induced by chronic stress, so as to explore the biological mechanism of EA for depression.

METHODSTwenty-four SD rats were randomly divided into a control group, a model group and an EA group, 8 cases in each one. Rats in the control group were treated with normal diet for 21 days without any treatment. In the model and EA group, rat model was established by chronic unpredictable stress combined with solitarily feeding method, and rats in the EA group was treated with EA at "Baihui" (GV 20), "Yintang" (GV 29) 1 h before stress stimulation everyday, 2 Hz in frequency and intensity was favorable with the head of rat slightly shivering. The needles were retained for 20 min, once a day for totally 21 days. After EA treatment, open-field experiment was adopted to observe the behavioral improvement; the rats temperatures were monitored at six time points (2:00, 6:00, 10:00, 14:00, 18:00, 22:00) and orbital blood sampling was collected. The level of serum MT was tested by enzyme linked immunosorbent assay. The circadian rhythm changes of temperature and serum MT in each group were compared.

RESULTSThe numbers of horizontal movement and vertical movement in the model group were obviously lower than those in the control group (both P < 0.05), while those in the EA group were significantly improved compared with those in the model group (both P < 0.01). The circadian rhythm of temperature and MT disappeared in the model group, which was improved into normal level after EA treatment.

CONCLUSIONThe electroacupuncture has regulation effects on circadian rhythm of temperature and melatonin in depression rat model induced by chronic stress.

OBJECTIVETo study the effect of dihydroartemisinin (DHA) combined irradiation on the apoptosis of human lung cancer GLC-82 cells and to study its mechanism.

METHODSThe growth inhibition rate of GLC-82 cells acted by different concentrations DHA was detected using MTT assay at 24, 48, and 72 h, respectively. Clone forming test was used. With multi-target single-hit model, the radiosensitization effect was assessed by calculating sensitizing enhancement ratio (SER).The effect of DHA combined irradiation on the apoptosis of GLC-82 cell cycle distribution and apoptosis were measured by flow cytometry. The protein expression of p53, p21, Bcl-2, and Bax were detected by Western blot.

RESULTSDifferent concentrations DHA (4, 8, 16, 32, 64, and 128 μg/mL) had cytotoxicity on GLC-82 cells. The IC50 for 24, 48, and 72 h was 38.25,20.58, and 10.36 μg/mL, respectively, in obvious dose- and time-dependent manner. The growth inhibition rate was more significantly increased than that of the blank control group (P < 0.01, P<0.05). DHA had sensitization enhancement effect on GLC-82 cells, with SER of 1.4. DHA combined irradiation could obviously change the structure of GLC-82 cells cell cycle and induce apoptosis (with the apoptosis rate of 21.5%), which was significantly different from that of the blank control group (P < 0.05). Western blot showed the expression of p53 and p21 protein could be increased by DHA combined irradiation, and the expression of Bcl-2 protein down-regulated (P <0.01, P <0. 05).

CONCLUSIONSDHA had stronger cytotoxicity and radiosensitization on GLC-82 cells. Its mechanisms might lie in making the arrest of GLC-82 cells' growth at G0/G1 phase, decreasing the ratio of cells at S phase, restoring the function of p53, decreasing the expression of Bcl-2 protein, and inducing apoptosis in GLC-82 cells.
