Aconitum, as a kind of common traditional Chinese medicine, contains multiple biological active substances, with a very high medicinal value but high toxicity. Its major toxic ingredients are aconitine, mesaconitine and hypaconitine, which are also efficient ingredients. Therefore, the safety of its clinical application has aroused wide attention. With the constant deepening of drug development studies, people want to learn about its toxic mechanism and the regularity of its emergence and development of its toxicology, so as to make a scientific and rational assessment for its safety. Therefore, toxicokinetics and metabonomics have gradually become important content in the new drug assessment. During the development of drug performance, it is crucial to establish a scientific, objective and standardized Aconitum safety evaluation system and correctly assess and utilize its toxicity. Having summarized studies on metabonomics and toxicokinetics of Aconitum drugs in recent years, authors proposed to strengthen the studies on Aconitum drug safety assessment and establish a scientific and standardized safety evaluation system as soon as possible, in order to make the national treasure more useful.

ObjectiveTo investigate the clinical significance of peripheral blood lymphocyte subsets in patients with idiopathic inflammatory myopathy (ⅡM).MethodsPeripheral blood lymphocyte subsets was determined by flow cytometry in 89 patients with polymyositis(PM ) or dermatomyositis ( DM ).The association between clinical features and peripheral blood lymphocyte subsets was analyzed by F test,t test and x2 test.ResultsPatients with active DM showed significant decreases in counts of CD3+ cell,CD3+CD4+ cell and CD3+CD8+ cell[(8±4),(5.4±2.8) and (2.6±1.6) ×108/L respectively],compared with those in inactive DM [(16±6), (10.4±5.6) and (5.6±3.8) ×108/L respectively] and healthy controls [(14±4), (8.3±2.8) and (4.6±1.7) ×108/Lrespectively](F=12.901,8.257,7.084; P＜0.05).Logistic regression analysis indicated that myositis disease activity could influence the counts of peripheral blood CD3+ cell,CD3+CD4+ cell and CD3+ CD8+ cell (b=0.211,0.344,0.289; P＜0.05 ).ILD in ⅡM could influence the counts of CD3+ cell and the ratio of CD3+CD4+cell (b=0.928,1.974; P＜0.05 ).Logistic regression analysis indicated that the count of CD3+CD8+ cell was risk factor for death,and the relative risk was 0.989(b=-0.011 ; P＜0.05).ConclusionPeripheral blood lymphocyte subsets may be regarded as useful laboratory parameters for monitoring RA disease activity.Decreased CD8+ T cell may predict a poor outcome of patients with IIM.

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.

In 2013, the World Health Organization reported the first case of human infection with a new influenza A (H7N9) virus in China. This has caused damage and panic within certain areas in China. Therefore, analysis of this virus with bioinformatics technology is very necessary. Neuraminidase (NA) is one of the most important antigens of the influenza virus and an important target for anti-flu drugs. In this study, the nucleotide and protein sequences of NA gene of A/H7N9 influenza viruses were retrieved from the NCBI database, and MEGA 5.0 software was employed to construct a phylogenetic tree based on the nucleotide coding sequence; BioEdit software was used to align the nucleotide and protein sequences of NA and calculate the homologies of nucleotides and amino acids and then to analyze the important mutation sites of NA gene. The results demonstrated that the spread of influenza virus H7N9 showed certain geographical and temporal relations. The H7N9 virus isolated from China in 2013 belonged to Euroasiatic serotype, and its NA stalk region hadobvious variation, which may be one of the reasons that this virus infects human. These analyses may be very helpful for understanding the evolutionary relationship and mutation trend of A/H7N9 influenza viruses.

OBJECTIVETo study the effects of polychlorinated biphenyl (PCB) on bcl-2 and TGFbeta1 expression in rat testes.

METHODSForty male Wistar rats were divided into 4 groups at random: Group A (normal control), Group B (fed on 10(-8) mol/L PBC), Group C (feb on 10(-7) mol/L) and Group D (feb on 10(-6) mol/L). After three months, all the rats were killed, the animal model established, and observations made on the expression of bcl2 and TGFbeta1 in the rat testis using the optical microscope and immunohistochemical techniques.

RESULTSThe damage to the structure of the testis was related to the dosage of PCB: the higher the dodage, the more serious the damage. PCB induced the expression of bcl-2 and TGFbeta1. The TGFbeta1 expression was significantly higher in the highest dosage group than in others (P < 0.01 ), and the bcl-2 expression was dramatically higher in Group C than in other groups (P < 0.01).

CONCLUSIONPCB can cause injury in rat testes.

Objective:To evaluate the reliability and validity of the Chinese version of the Personal and Social Performance scale (PSP-CHN) in patients with schizophrenia.Methods:Totally 165 out-patients and in-patients meeting the DSM-IV-TR criteria for schizophrenia were entered in the study.Ten of subjects was included the intra-rater reliability training.The Global Assessment of Functioning Scale (GAF) was regarded as the' gold standard' to investigate the validity of PSP-CHN,and the Positive and Negative Rating Scale was used to assess the severity of disease to explore the correlative validity,in the other 155 subjects.Five to seven days after the first PSP-CHN interview,the second PSP-CHN was evaluated by another investigator to assess the test-retest reliability among 66 subjects.Twenty-seven subjects with the score of Positive and Negative Syndrome Scale (PANSS) more than 60 were followed up for 8 weeks of standardized pharmacotherapy.By the end of 8 week of treatment,the PANSS and PSP-CHN were assessed again to explore the sensitivity of PSP-CHN.Results:The internal consistency (Cronbach α=0.84) and the inter-rater reliability (κ value=0.56,ICC=0.94 for PSP-CHN total score) were good.The test-retest reliability was high [intraclass correlation coefficient (ICC) of 0.95].The scale showed good construct validity with statistically significant correlations with the Global Assessment of Functioning Scale (GAF) (ICC of 0.95).The PSP-CHN score had a good negative correlation with the PANSS total score(r=-0.79,-0.57,-0.63 and -0.71,respectively,P<0.01).After 8 week treatment,PSP-CHN total score was increased with the improvement of PANSS,and the responder showed higher increasing of PSP-CHN total score (21.2) than those partial responder(10.2),significantly.Conclusion:The Chinese version of the PSP-CHN is a convenient and valid instrument to assess the personal and social functions of stabilized and acute patients with schizophrenia.

Objective To report our experience with retroperitoneoscopic nephroureterectomy with excision of a bladder-cuff for renal pelvic and ureteral tumors.Methods Thirty-five patients (21 women and 14 men;mean age,67 years;age range,49 -82 years) with upper urinary tract tumors underwent retro- peritoneal laparoscopic nephrourcterectomy with excision of a bladder-cuff.Of the 35 cases,15 had pelvic tumors and 20 had ureteral tumors;19 cases had the tumors on the right side and 16 on the left.Two cases had ureteral tumors combined with bladder tumors.One case had bilateral ureteral tumors then concomitantly had bladder tumors.The needle electrode was used to circleround incise the bladder thoroughly 0.5 cm away from the ureterostoma.Three trocars in the waist were used for dissecting the kidney;and the ureter was dis- sected as far distally downward.Then an incision of 5-9 cm was created in the lower abdomen to allow dis- section of the distal ureter and bladder-cuff and intact specimen extraction.Results The operation was successful in all 35 patients.The mean operative time was 3.1 h ( range,1.5-6.0h).The mean estimated blood loss was 166 ml (range,20-1600 ml).Four cases received blood transfusion.The patient's activity re- covered in 20-32 h after operation.Postoperative pathology showed transitional cell carcinoma in 30 cases, poorly differentiated adenocareinoma in 2 (ureter),squamous cell carcinoma in 1 (ureter),leiomyosarcoma in 1 (ureter),xanthogranulomatous pyelonephritis in 1.Duodenal leakage occurred in 1 patient who had had dialysis a drainage catheter was placed on the third d after operation,and the patient died of heart failure af- ter 2 months.Postoperative vesical irrigation was performed to prevent tumor recurrence.The mean hospital stay was 11 d.During a mean follow-up of 14 months(range,1-32 months),1 patient developed pelvic me- tastasis and was alive with the tumor.The other 33 patients survived free of tumor to date.No patient had re- current transitional cell carcinoma of the bladder.Conclusions Our data demonstrate that retroperitoneo- scopic nephroureterectomy for renal pelvic and ureteral tumors has shorter incision and more rapid postopera- tive recovery compared with open surgery.Using resectoscope to resect the termination of ureter allows more complete excision of the ureter.

Objective To study the proliferative inhibition and apoptosis promoting activity of oxymatrine on human lung cancer cells (A549) and human hepatocellular carcinoma cells (HepG-2) in vitro,and make a comparison.Methods Effect of oxymatrine on the proliferation activity of two kinds of tumor cells were compared by MTT method and growth curve method.HE staining,Hoechst 33258 fluorescent staining and transmission electron microscopy were used to compare morphological changes.Results MTr results showed that,compared with control group,the survival rate of oxymatrine 200,400,and 800 μg/mL concentration group in A549 and HepG-2 cells decreased significantly (P ＜ 0.05,0.01),half inhibitory concentration (IC50) were 1055.45 and 774.11 g/mL respectively;The growth curve showed that,compared with control group,the number of cells in oxymatrine group of HepG-2 cells cultured for fourth and fifth day and A549 cells cultured for fifth day decreased significantly (P ＜ 0.05,0.01).Oxymatrine affected morphological changes of HepG-2 cells more significantly than A549 cells.The number of cells in the oxymatrine group was significantly reduced;And the cell villi was decreased,the nucleus was small and round,and the cell apoptosis morphological characteristics were obvious.Conclusion Oxymatrine can inhibit the proliferation cells and promote the apoptosis of tumor cells.It affected HepG-2 cells more obviously,which suggests that it may have different sensitivity to different tumor cells.

OBJECTIVETo observe the effect of Compound Zhajin Granule (CZG) on Toll-like re-ceptor 4 (TLR4) signaling pathway in high-fructose corn syrup induced NASH mice.

METHODSThirty 6-week-old male C3H mice were divided into the high fat and high fructose (HFHFr) group (n = 20) and the control group (n = 10) according to body weight. Mice in the HFHFr group ate high fat diet and drank 20% fructose water, while those in the control group ate common diet and drank common water. After 8 weeks mice in the HFHFr group were divided into two group according to body weight, the HFHFr group and the CZG group, 10 in each group. Mice in the CZG group were fed with high fat forage and 20% fructose water, and administered with 50 mL/kg 12. 8% CZG (prepared by hawthorn, Radix Curcumae, Alisma Orientale, Fritillaria Thunbergii, Silybum Marianum, peach seed in the ratio of 3:1.5:1.5:2:1.5:2:1) by gastrogavage. Mice in the HFHFr group were fed in the same way and daily administered with equal volume of distilled water by gastrogavage. Sixteen weeks later all mice were sacrificed. Body weight, liver wet weight, liver function, and lipid metabolism were detected. Pathological changes of liver tissues were assessed by HE staining, oil red O staining, and Masson staining. Expressions of TLR4, myeloid differentiation factor 88 (MyD88), tumor necrosis factor-alpha (TNF-α) were detected using immunohistochemical staining and real-time fluorescent quantitative PCR.

RESULTSBody weight, alanine aminotransferase (ALT), aspartate aminotransferase (AST) were obviously lower in the CZG group than in the HFHFr group (P < 0.05); oil red O stained area and density were decreased more in the CZG group than in the control group. HE staining showed ballooning inflammation was reduced more in the CZG group than in the HFHFr group. Masson staining was negative. Positive rates of TLR4 and MyD88 and mRNA expressions were significantly lower in the CZG group than in the HFHFr group (all P < 0.05).

CONCLUSIONCZG could significantly inhibit TLR4 signaling pathway of liver in NASH mice.
