Objective Evaluate the immunotoxicity of Ginenoside Compound K Injection.Methods Active Systemic Anaphylaxis (ASA)tests and Passive Cutaneous Anaphylaxis (PCA)tests were used to evaluate Ginenoside Compound K Injection.Results In the ASA tests,positive control group showed pole-strength anapbylaxis,both the high-dose group and the low-dose group of Ginenoside Compound K Injection didn't produce allergic reaction and the body weights of all groups showed no significant differences.In the PCA tests,all rats of positive control group caused blue spots with their diameters bigger than 5 mm (diameters on the left side of blue spots was (10.1± 3.34) mm and diameters on the right side of blue spots was(7.57± 1.94)mm.Serum IgE was significantly increased.While both high dose and low dose of Ginenoside Compound K Injection group didn't show blue spots with their diameters greater than 5 mm and their IgE levels showed no significant differences compared with negative control group.Conclusion Ginenoside Compound K Injection showed no immunotoxicity under these experimental conditions.

Objective:To study the role of angiopoietin-2(Ang-2) in angiogenesis in oral squamous cell cacinoma(OSCC). Methods:Expression of angiopoietin-2 and CD_34 in 41 cases of OSCC(13 cases with lymph node metastasis)and 10 cases of normal oral mucosa was detected by immunohistochemical SABC method. Microvessel density(MVD) in the samples was counted under microscope. Results:Ang-2 was detected in 28 out of 41(68.29%) cases of OSCC and 2 out of 10(20%) of normal oral mucosa(P

Objective To explore the effect of Yiqi-jianpi-jiedu recipe decoction containing serum on Oxaliplatin-induced HepG2 Human hepatoma cell survivin, caspase-3, caspase-9 expression. Methods The serum pharmacological method was used to prepare nourishing Qi and invigorating spleen decoction containing serum of rat. The HepG2 human hepatoma cells were divided into Chinese herb containing serum group, chemotherapy with Oxaliplatin (OXA) group and the combination group (medicine containing serum and OXA), and the blank group without drugs. Apply MTT assay, Western Blotting method and RT-PCR method to detect the cell inhibition rate and survivin, caspase-3, caspase-9 protein and gene expression changes. Results Compared with the blank group, the inhibition rate of HepG2 Human hepatoma cell was significantly higher in Chinese herb containing serum group, chemotherapy group and the combination group (P < 0.05). Compared with thechemotherapy group and Chinese herb containing serum group, the Survivin (0.151 ± 0.054 vs. 0.288 ± 0.089, 0.375 ± 0.063) and the expression of Survivin mRNA (0.205 ± 0.091 vs. 0.487 ± 0.073, 0.725 ± 0.092) of the conbination group downgraded significantly lower (P < 0.05 or P< 0.01). Compared with chemotherapy group and Chinese herb containing serum group, the caspase-3 (0.821 ± 0.079 vs. 0.634 ± 0.098, 0.487 ± 0.102), caspase-9 (0.901 ± 0.047 vs. 0.709 ± 0.054, 0.402 ± 0.012) expression, caspase-3 mRNA (1.928 ± 0.226 vs. 1.564 ± 0.195, 1.287 ± 0.312) and caspase-9 mRNA (2.063 ± 0.517 vs. 1.536 ± 0.084, 1.019 ± 0.182) expression of the conbination group upgraded significantly higher (P < 0.05 or P < 0.01). Conclusions Nourishing-Qi and invigorating spleen decoction containing serum may affect Oxaliplatin-induced HepG2 apoptosis mechanism through increasing the suppression on Survivin and promoting the expression of caspase-3 and caspase-9 protein and genes. This research provided important experimental basis for clinical application of traditional Chinese medicine treating liver cancer.

Objective To establish brain hypoxic-ischemic (HI) model using postnatal day 3(P3) SD rats and evaluate the apoptotic neuronal cells in cerebral cortex and neurofunctional development.Methods The P3 rats were randomly divided into HI group (n=35) and control group(n=18).HI was induced in P3 rats with right carotid artery ligation followed by 2.5 h hypoxia in 60 mL?L-1 oxygen at 37 ℃.The injury of neural cells in the cerebral cortex was evaluated by tumor necrosis factor receptor-1(TNF-R1),Caspase-3 immunostaining and Hematoxylin-Eosin (HE) staining in 24 h and 7 d after HI,respectively.Furthermore,the neurofunctional development was evaluated by negative geotaxis reflex and eye opening time.The data were analyzed by SPSS 12.0 software.Results Caspase-3 and TNF-R1 positive cells were abundant in the ipsilateral cortex at 24 h after HI,compared with contralateral part and control group(P

Objective To evaluate the targeted antimicrobial prophylaxis in men undergoing trans-rectal ultrasound guided prostate biopsy based on rectal swab culture results.Methods From July 2008 to April 2012 we studied differences in infectious complications in men who received targeted vs standard empirical ciprofloxacin prophylaxis before transrectal ultrasound guided prostate biopsy.All 344 patients were divided into 3 groups according to their hospital records,inculding group A:without antimicrobial prophylaxis(105 eases) ;group B:antimicrobial prophylaxis with fluoroquinolone(117 cases) ;group C:targeted prophylaxis used rectal swab cultures results(122eases).All cases received enema with diluted iodophors before biopsy.We identified men with infectious complications within 7 days after transrectal ultrasound guided prostate biopsy using the electronic medical record,following 3 conditions.Results In group A of 105 case,17 cases of fever were recorded,including prostatic abscess of 3 cases and septicemia of 1 case.Three cases of fever were occurred in group B,including 1 case of bacteremia and 1 case of prostatitis.No infectious complications were recorded in group C.Conclusions Targeted antimicrobial prophylaxis was associated with a notable decrease in the incidence of infections complications after transrectal ultrasound guided prostate biopsy,although fiuoroquinolone can provide good protective effets.

Objective The purpose of the present study was to develop an animal model of type II diabetic coro-nary heart disease in Zuker diabetic fatty ( ZDF) rats.Methods The ZDF rat model of type II diabetic coronary heart disease was prepared by high-fat diet feeding combined with continuous injection of isoprenaline hydrochloride (ISO) in a dose of 1 mg· mL-1 for 10 consecutive days.Serum creatine kinase (CK), and creatine kinase izozyme (CK-MB), ST segment in electrocardiogram ( ECG) and myocardial pathological changes were detected to evaluate the rat model.Results CK of both the control and model groups was gradually increased with ISO injections, while CK-MB increased first and then decreased.The ST segment in ECG part II had significant changes.The pathological examination found that about half of the myocardial cross section in the model group was necrotic after injections of ISO for 5 days and more than 3/4 of the my-ocardial cross section was necrotic after injection of ISO for 10 days.The results indicated that ISO caused myocardial inju-ry in ZDF rats.Conclusions The variation of CK-MB, CK, ST segments in ECG and myocardial necrosis indicate that the model is successfully established.The use of high-fat diet combined with continuous injection of isoprenaline hydrochlo-ride in a dose of 1 mg· mL is a simple way to develop a Zuker diabetic fatty rat model of type II diabetic coronary heart dis-ease.

Objective To investigate the clinical application of parenteral nutrition drugs and promote the rational use of drugs.Methods The data of parenteral nutrition drugs used in our hospital were analyzed,including the quantity,the amount of money,the scope and purpose,etc.The rationality of drug use was reviewed by prescription comment simultaneously.Results On similar medicines comparison,the fat emulsion,amino acids (17) and glucose (11％) injection (1440mL) and fat emulsion and amino acids (18) injection (1 000mL),which were designed according to the basal metabolic rate in patients were far greater than the fat emulsion,amino acids(17) and glucose (11％) injection (1 920mL) of the added value of design.And the balanced amino acid preparations in compound amino acid in 18 AA-Ⅳ usage,was far greater than 18 AA-Ⅱ and 18 AA.Fat emulsion preparation with concentration of 20％ dosage was bigger,because the price advantage,ordinary long-chain fat milk consumption was greater than the long chain fatty milk.In terms of drug use rationality,the usage,dosage,compatibility and adverse reactions of parenteral nutrition drugs were analyzed.The dosage,frequency and compatibility problems still needed to be improved.Conclusion The use of parenteral nutrition drugs were basic reasonable,but we should strictly control the indications for parenteral nutrition support,such as drug compatibility,using frequency to strengthen management and reasonable application of drugs to improve medication safety.
