3. Effect of vitamin K2 and benazepril combination therapy on gastric cancer in nude mice
Chinese Pharmaceutical Journal 2012;47(3):186-189
OBJECTIVE: To investigate the effect of vitamin K2 combined with benazepril on human gastric cancer in nude mice. METHODS: SGC-7901 human gastric cancer cells were implanted into BALB/c nude mice to establish the cancer model. Fourteen days after the subcutaneous implantation of cancer cells, 40 nude mice were randomly divided into 4 groups; control group, vitamin K2 therapy group, benazepril therapy group and combination therapy group (vitamin K2 + benazepril). After 14 d, the tumor growth was evaluated, apoptosis indices were examined by TUNEL assay, and VEGF and caspase 3 expression were assessed by immunohisto-chemical staining. RESULTS: Compared to the control group, tumor weights were decreased and apoptosis indexes was significantly increased in the therapy groups (P < 0.05), the protein expression of caspase 3 were up-regulated, and VEGF were decreased in the therapy group (P < 0.05), and all the changes above were more significant in combination therapy group than vitamin K2 or benazepril group (P < 0.05). CONCLUSION: The combination of vitamin K2 and benazepril enhances anti-tumor efficacy possibly through angiogenesis suppression and apoptosis induction.

To investigate the effects of Tongxinluo capsule on sciatic nerve apoptosis in spontaneous type II diabetic KK/Upj-Ay mice, in order to explore its mechanism for improving diabetic peripheral neuropathy (DPN). KK/Upj-Ay mice were selected as the DPN animal model and randomly divided into the model, Tongxinluo low, middle and high group (1, 2, 4 g x kg(-1)). C57BL/6 mice were selected as the control group. Mice were given intragastrically for 12 weeks. Paw withdrawal latency, motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) were detected. Apoptotic rate were detected by FCM. Bcl-2, Bax, Caspase-3 mRNA and protein expression in sciatic nerve were examined by Real-time PCR and Western blot. p38MAPK, p-p38MAPK expression were examined by Western blot. In this study,the authors found that Tongxinluo capsule could increase paw withdrawal latency, MNCV and SNCV. Apoptotic rate of sciatic, the expression of Bax and caspase-3 were lower, while Bcl-2 expression was higher in Tongxinluo group than those in model mice. The expression of p-p38MAPK significantly decreased in Tongxinluo group. The results showed that Tongxinluo capsule has protective effects on diabetic peripheral neuropathy of mice via inhibiting cell apoptosis and suppressing the expression of p-p38MAPK.

The aim of this study is to elucidate the protective and anti-apoptotic effects of insulin-like growth factor 1 ( IGF-1 ) against β-amyloid (Aβ) and investigate the effect of IGF-1 on Aβ-induced tau phosphorylation. Cell viability was measured using the MTT (3-(4,5-dimethylthiazolyl-2 )-2,5-diphenyltetrazolium bromide) assay, early apoptosis and late apoptosis/necrosis were analyzed by flow cytometry using Annexin V-FITC and propidium iodide (PI) double staining, and morphology was examined by Hoechst 33342 staining. Tau phosphorylation was detected using AT8 immunostaining. Preincubation of cultured rat hippocampal neurons with IGF-1 for 24 h prevented cytotoxicity induced by Aβ25-35 for 48 h. The MTT value significantly increased from 54.51% to 61.8% of the control group, and the percentage of Hoechst 33342-positive cells decreased from 30.77% to 22.81%. Incubation with Aβ25-35 for 48 h caused a marked increase in the percentages of Annexin V-FITC single-labeled cells (Annexin V +/PI-) and Annexin V/PI double-stained cells (Annexin V +/PI + ) (3.41% and 19.47% , respectively), which were significantly decreased by pretreatment with 100 ng/ml of IGF-1 for 24 h (to 2.98% and 15.16% , respectively). Aβ25-35 treatment increased tau phosphorylation and AT8 positive cells were 41.84%. This effect could be inhibited by different concentrations of IGF-1. Our findings showed that IGF-1 protected against Aβ-induced cytotoxicity, decreased the percentage of early and late apoptosis/necrosis cells, and inhibited tau phosphorylation, which may be the cellular mechanisms for its neuroprotective action.

Autophagy is a highly conservative biological behavior in eukaryotic cells .This dynamic process involves wrappingcytoplasmic components and combining with lysosomes in cells for catabolism .Auto-phagy can not only take part in maintaining homeostasis ,but also be closely related with tumor development and resistant.Therefore,autophagy is a potential target for antitumor drug resistant .Specific inhibition of autophagy in cancer cells combined with chemotherapy is expected to be an effective cancer treatment strategy .

BACKGROUND:Both local infiltration analgesia and femoral nerve block are used for the pain management after total knee arthroplasty. Controversy stil remains regarding the optimal technique for pain relief. OBJECTIVE:To systematical y evaluate analgesic effects of local infiltration analgesia and femoral nerve block after total knee arthroplasty. METHODS:Databases including PubMed, EMBASE, the Cochrane Library, Web of Science and CBM, were comprehensively searched to identify randomized control ed studies comparing local infiltration analgesia with femoral nerve block. Two reviewers independently selected trials, included literatures, extracted data, and assessed the methodological qualities of included studies according to Cochrane Handbook for Systematic Reviews of Interventions Version 5.1.0. When there were different opinions, it was decided by the third author. Data were analyzed by RevMan 5.3 software. RESULTS AND CONCLUSION:(1) Eleven randomized control ed trials involving 566 patients were included. (2) At 24 and 48 hours (h) after surgery, there were no significant differences between the local infiltration analgesia and femoral nerve block groups, in Visual Analog Scale scores [MD24 h=0.15, 95%CI (-0.26, 1.28), P>0.05;MD48 h=0.19, 95%CI (-0.06, 0.44), P>0.05] in the resting state, and [MD24 h=-0.01, 95%CI (-0.51, 0.48), P>0.05;MD48h=0.18, 95%CI (-0.45, 0.82), P>0.05] in the active state, amount of analgesic drug use [MD24 h=-2.23, 95%CI (-5.63, 1.16), P>0.05;MD48 h=2.44, 95%CI (-1.08, 5.95), P>0.05], hospital stay [MD=0.05, 95%CI (-0.40, 0.50), P>0.05], postoperative nausea and vomiting [OR=1.09, 95%CI (0.39, 3.04), P>0.05] and postoperative infection [OR=0.99, 95%CI (0.44, 2.59), P>0.05]. (3) These results indicated that the analgesic effect of local infiltration analgesia was identical to that of femoral nerve block after total knee arthroplasty. Due to its simple operation, local infiltration analgesia can be used as a standard analgesia method after total knee arthroplasty.

Objective To investigate the present situation and outcome of cardiopulmonary resuscitation (CPR) for pediatric in-hospital cardiopulmonary arrest and to analyze the prognostic risk factors.Methods Data were collected from October 2008 till October 2011 using Ustein style.Patients older than 28 days who received CPR were evaluated.Returning of spontaneous circulation(ROSC) more than 24 hours was the primary outcome.Neurological outcome was assessed by pediatric cerebral performance categories half year after discharge.Results Of the 36 patients,15 (41.7%) achieved sustained ROSC.Seven (19.4%) patients survived to discharge.Single factor analysis indicated that the beginning heart rhythm,defibrillation and original disease were significantly different between the two groups(P <0.05).The beginning heart rote of the patient in ROSC > 24 h group was mostly sinus bradycardia.Patients who need defibrillation had bad prognosis.Patients with heart disease had a lower rate of ROSC > 24 h.At half year follow-up study,4 patients had 1 or 2 score,1 patient had 4 and 1 had 5 score in the pediatric cerebral performance categories scales.Condusion The successful rate of CPR in our hospital was the same as that in developed country.The beginning heart rhythm,defibrillation and original disease were associated with the outcome.Most of the patients who survived to discharge had a good neurological outcome.
