Objective: To observe the impact of vareniline tartrate on vascular endothelial function and inlfammatory factor releasing in acute coronary syndrome (ACS) patients with nicotine dependence after smoking withdrawal treatment.
Methods: We recruited the in-hospital ACS patients who were smoking ≥10 cigarettes/day for more than 10 years with at least moderate nicotine dependence, and randomly divided them into 2 groups: Varenicline group, the patients received oral medication for 2 weeks and Self withdrawal group, the patients without medication assistance.n=52 in each group. All patients received (10-30) min daily mission and consulting for quit smoking for 2 weeks. The basic information was recorded and blood levels of NO, IL-6 and ET-1 were compared before and after withdrawal treatment.
Results: Compared with they were before, after 2 weeks withdrawal treatment, in Varenicline group, blood levels of ET-1 decreased as (33.950 ± 1.439) ng/L vs (170.198 ± 12.602) ng/L and IL-6 decreased as (0.103 ± 0.020) ng/L vs (0.307 ± 0.051) ng/L; in Self withdrawal group, ET-1 decreased as (60.795 ±7 .036) ng/L vs (170.511 ± 12.374) ng/L, all P<0.05; while NO levels were similar,P>0.05. After treatment, ET-1 level in Varenicline group (33.950 ± 1.439) ng/L was lower than Self withdrawal group (60.795 ± 7.036) ng/L and IL-6 level in Varenicline group (0.103 ± 0.020) ng/L was also lower than Self withdrawal group (0.258 ± 0.042) ng/L, allP<0.05; while NO levels were similar between 2 groups,P>0.05.
Conclusion: Compared with self withdrawal, varenicline tartrate may effectively inhibit inlfammatory factor releasing in ACS patients with nicotine dependence, and therefore improve the vascular endothelial function.

Methods Totally 94 elderly patients with NSCLC were divided into observation group and control group, with 47 cases in each group. Both groups were given targeted cryoablation therapy and under CT review after surgery to observe lesions condition. Observation group was given Qingfei Sanjie Pills, once a bottle, twice a day, orally, for three months. Recent efficacy of the two groups were evaluated. The levels of IgG, IgA, CD3+, CD4+, CD8+, and complications in the two groups were detected. The survival rate of 1 year, 2 years and 3 years in the two groups were observed. Results Two cases in the observation group and three cases in the control group were invalid. The total effective rate was 84.4% (38/45) in observation group and 65.9% (29/44) in the control group, with statistical significance (P<0.05). After the treatment, the levels of IgG, IgA, CD3+, CD4+and CD8+in the observation group were significantly higher than the control group (P<0.05). After treatment, the incidence rates of increased cough, postoperative pain, bloody sputum, fever and nausea and vomiting in the observation group were lower than the control group. The 1 year, 2 years and 3 years survival rates were 91.1%, 75.6% and 64.4% in observation group, and 79.5%,63.6% and 52.3% in the control group,with statistical significance(P<0.05).Conclusion Qingfei Sanjie Pills combined with targeted cryoablation therapy on elderly patients with advanced NSCLC has good clinical efficacy, which can improve immune system of patients and increase survival rate.

Wuzhuyu Tang is a classical formula for treating migraine, but its' pharmacological ingredients is unclear yet. Present study employed the everted intestinal sac model to collect the absorption samples of 10 kinds of Wuzhuyu decoction, and then analyzed the contents of 9 ingredients in Wuzhuyu Tang and absorption samples quantitatively or semi-quantitatively by HPLC-DAD method. Reserpine was used to establish the mice model of migraine, and then the contents and activities of 5-hydroxytryptamine, noradrenaline, dopamine, nitric oxide and nitricoxide synthase in brain tissues and serums were determined respectively after oral administration of Wuzhuyu Tang. Using the partial least squares regression method to correlate the total absorption quantity of 9 ingredients and pharmacodynamics. The result shows that limocitrin-3-O-beta-D-glucoside, ginsenoside Rg1 and Rb1, rutaevine, limonin, evodiamine and rutaecarpine are the main ingredients influenced the effects in absorption samples in everted intestinal sacs, especially ginsenoside Rg1, rutaevine, evodiamine and rutaecarpine among them have obvious improving effects to most pharmacodynamics index, might be the pharmacological ingredients influenced the therapeutical effects of Wuzhuyu Tang treating migraine.

Atropa belladonna is a medicinal plant and main commercial source of tropane alkaloids (TAs) including scopolamine and hyoscyamine, which are anticholine drugs widely used clinically. Based on the high throughput transcriptome sequencing results, the digital expression patterns of UniGenes representing 9 structural genes (ODC, ADC, AIH, CPA, SPDS, PMT, CYP80F1, H6H, TRII) involved in TAs biosynthesis were constructed, and simultaneously expression analysis of 4 released genes in NCBI (PMT, CYP80F1, H6H, TRII) for verification was performed using qPCR, as well as the TAs contents detection in 8 different tissues. Digital expression patterns results suggested that the 4 genes including ODC, ADC, AIH and CPA involved in the upstream pathway of TAs, and the 2 branch pathway genes including SPDS and TRII were found to be expressed in all the detected tissues with high expression level in secondary root. While the 3 TAs-pathway-specific genes including PMT, CYP80F1, H6H were only expressed in secondary roots and primary roots, mainly in secondary roots. The qPCR detection results of PMT, CYP80F1 and H6H were consistent with the digital expression patterns, but their expression levels in primary root were too low to be detected. The highest content of hyoscyamine was found in tender stems (3.364 mg x g(-1)), followed by tender leaves (1.526 mg x g(-1)), roots (1.598 mg x g(-1)), young fruits (1.271 mg x g(-1)) and fruit sepals (1.413 mg x g(-1)). The highest content of scopolamine was detected in fruit sepals (1.003 mg x g(-1)), then followed by tender stems (0.600 mg x g(-1)) and tender leaves (0.601 mg x g(-1)). Both old stems and old leaves had the lowest content of hyoscyamine and scopolamine. The gene expression profile and TAs accumulation indicated that TAs in Atropa belladonna were mainly biosynthesized in secondary root, and then transported and deposited in tender aerial parts. Screening Atropa belladonna secondary root transcriptome database will facilitate unveiling the unknown enzymatic reactions and the mechanisms of transcriptional control.

OBJECTIVETo evaluate the prognostic effects of neoadjuvant chemotherapy (NAC) in patients with local advanced gastric cancer.

METHODSWe retrospectively analyzed prognosis in 191 patients with advanced gastric cancer, of whom 71 were treated with NAC and 120 received surgery only between February 2007 and July 2013. Postoperative complication rate was recorded. Survival by clinicopathological features, pathological T and N stages, and histopathological tumor regression was retrospectively compared between the two groups.

RESULTSAccording to Response Evaluation Criteria in Solid Tumors, none of the 71 patients in the NAC followed by surgery group showed complete response, 36 showed partial response, 25 had stable disease, and 10 had progressive disease. The chemotherapy response rate was 50.7%; the disease control rate was 85.9%. Grade 3/4 adverse events were seen in less than 20% patients, with acceptable toxicities. No difference was found in the overall postoperative complication rates between the two groups (7 versus 22 cases, P=0.18). Median survival time was significantly different, at 54 months in the NAC combined with surgery group and 25 months in the surgery-only group (P=0.025).

CONCLUSIONIn patients with operable gastric adenocarcinomas, NAC can significantly improve overall survival without increasing surgical complications.

OBJECTIVETo explore the possible mechanism of cyclovirobuxine D (CVB-D) in countering and inducing arrhythmia, by way of studying its electro-physiological effect on ventricular papillary muscles of rats in vitro.

METHODSThe transmembrane potential of rat's isolated right ventricular papillary muscles were recorded using conventional glass micro-electrode technique.

RESULTS(1) CVB-D in concentration of 13.3-63.3 micromol/L, showed prolonging effect on the action potential repolarization time, mainly the action potential duration 50 (APD50), APD70 and APD90, in dose-dependent manner, in concentration of 33.3-63.3 micromol/L, it could inhibit the resting potential, action potential amplitude (APA) and maximum depolarization velocity (Vmax) in dose-dependent manner. (2) CVB-D also showed time-dependent effect, the effect initiated 10 min after 20 micromol/L was perfused in ventricular muscle, the APD50, APD70 and APD90 were potentiated gradually along with prolongation of action time and reached the peak at 30-40 min, without any potentiation thereafter. (3) CVB-D could markedly prolong the effective refractory period (ERP) of action potential, increase the ratio of ERP/APD. (4) CVB-D in concentration of 33.3 micromol/L could induce frequent, multifocal spontaneous arrhythmia in some cells when the action time was longer than 45 min.

CONCLUSIONCVB-D has the action of anti-ventricular arrhythmia, the mechanism is correlated with the prolongation of APD and ERP of ventricular muscle as well as the increase of ERP/APD ratio, while it also has the effect of inducing arrhythmia, the mechanism might be concerned with excessive prolongation of APD and the inhibition on RP, APA and Vmax.

Objective To investigate the serum levels of endothelin-1 (ET-1), tumor necrosis factor- α (TNF-α) and their dynamic changes in patients with delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) and their relation with the condition variation of the patients.Methods The serum ET-1 and TNF-α levels were determined with enzyme-linked immunno-sorbent assay (ELISA) in 31 patients with DEACMP, and the dynamic changes of patients' condition were monitored by use of the activity of daily living (ADL) scale, the information-memory-concentration test (IMCT) and the Hasegawa's dementia scale (HDS). The comparisons between patients with DEACMP and both 30 patients with acute carbon momoxide poisoning (ACMP) but without DEACMP and 30 normal controls were also conducted. Results At the acute stage of the DEACMP group, the serum levels of ET-1 and TNF-α were both significantly higher than those in the normal control group (P＜0.05); that of TNF-α was significantly lower than that in the ACMP group (P＜0.05), but that of ET-1 was not significantly different from that in the ACMP group (P＞0.05). The serum levels of ET-1 and TNF- α in the ACMP group were both significantly higher than those in the normal control group(P＜0.05). In the DEACMP group, the serum level of ET-1 at the convalescent stage was significantly lower than that at the acute stage (P＜0.05), but the serum level of TNF-α was not significantly different from that at the acute stage (P＞0.05). At the acute stage of the DEACMP group, ADL scores were significantly higher than those in norms, and IMCT scores and HDS scores were significantly lower than those in norms (P＜0.05). In the DEACMP group, the ADL scores at the convalescent stage were significantly lower than those at the acute stage (P＜0.05), IMCT scores and HDS scores were significantly higher than those at the acute stage (P＜0.05). Significant correlations between scores of any 2 of 3 scales in patients with DEACMP at both acute and convalescent stage were noted (P＜0.05). Conclusion The dynamic detection of serum ET-1 and TNF-α level variations could be used as an indicator for condition severity in patients with DEACMP.

OBJECTIVETo evaluate the efficacy and safety of the combination therapy of tamsulosin and solifenacin for mild and moderate benign prostatic hyperplasia (BPH) with overactive bladder (OAB).

METHODSWe randomly divided 166 patients with BPH and concomitant OAB into a mild obstruction symptom group (n = 88) and a moderate obstruction symptom group (n =78), 48 of the former group treated with 0. 2 mg tamsulosin + 5 mg solifenacin and the other 40 with 0. 2 mg tamsulosin; 36 of the latter group treated with 0. 2 mg tamsulosin + 5 mg solifenacin and the other 42 with 0. 2 mg tamsulosin, all administered once daily for 12 weeks. We obtained the International Prostate Symptom Score (IPSS), urine storage period symptom score (USPSS), voiding symptom score (VSS), Qmax, residual urine volume, OAB symptom score (OABSS) and adverse reactions, and compared them among different

RESULTSAmong the patients with mild obstruction symptoms, the combination of tamsulosin and solifenacin achieved remark-groups. able improvement in IPSS, USPSS, Qmax and OABSS as compared with the baseline (P < 0.05), but made no significant difference in the residual urine volume (P > 0. 05) , while tamsulosin improved IPSS only (P < 0.05). The combination therapy exhibited an obvious superiority over tamsulosin alone in improving IPSS (9.7 micro 3.0 vs 15.8 micro 3.3), USPSS (8. 1 micro 1.7 vs 12.3 micro 3.1), Qmax ([18.6 micro 2.3] ml/s vs [14.2 micro 2.3] ml/s ), and OABSS (5.3micro 1.3 vs 9.7 micro 2.7) (P < 0.05), but there were no obvious differences in residual urine, urine routine test results and adverse events between the two therapies ( P > 0. 05). In those with moderate obstruction symptoms, the combination therapy significantly improved IPSS, VSS, Qmax and OABSS (P < 0.05) but not the residual urine (P > 0. 05) in comparison with the baseline. The tamsulosin therapy achieved obvious improvement in IPSS, VSS, Qmax, OABSS and residual urine. The combination therapy showed a better effect than tamsulosin only in OABSS (4. 8 +/-1.5 vs 6.5 +/-2.5, P < 0.05), but no significant differences from the latter in IPSS, Qmax, VSS, routine urine test results, and adverse

CONCLUSIONCombination therapy of tamsulosin and solifenacin is obviously safe and efficacious in the treatment (P > 0.05). events of both mild and moderate BPH with concomitant OAB, and it is superior to tamsulosin alone.

OBJECTIVETo investigate the efficiency and safety of two-dose steroid combined with two-dose daclizumab and tacrolimus (FK506) regimen in liver transplant recipients.

METHODSThere were 74 patients who treated in the First Affiliated Hospital of Sun Yat-Sen University from September 2006 to March 2008. Expect for 7 patients who didn't measure up, 67 adult liver transplant recipients were randomized into two groups: conventional protocol group (n = 35) in which steroid was withdrawn in 3 months after operation, and two-dose steroid group (n = 32). Comparison of rejection, infection (bacteria, fungal and cytomegalovirus) and metabolic complications rates were studied between two groups.

RESULTSThere were significant differences between two groups in the rate of early postoperation hyperglycemia, the average dosage of insulin consumption among hyperglycemia recipients as well as the rate of diabetes mellitus, hypertension and infection during the follow-up period (P < 0.05). The rate of hypertension in early postoperation period, hyperlipemia and rejection rate during the follow-up period were similar in two groups (P > 0.05).

CONCLUSIONSTwo-dose steroid combined with two-dose daclizumab and tacrolimus would be a safe and efficient immunosuppression strategy without increase the acute rejection rate hazard, that could reduce post-transplant infection and other complications from side-effect of long-term usage of steroid.
