OBJECTIVE:To compare the efficacy and safety of Pingxiao capsule and Shendan Sanjie capsule combined with CP program in the treatment of non-small cell lung cancer (NSCLC) in stage Ⅳ. METHODS:132 NSCLC patients in stage Ⅳwere randomly divided into CP group,CP+Pingxiao group and CP+Shendan Sanjie group. CP group was treated with CP program;based on it,CP+Pingxiao group was orally treated with 6 Pingxiao capsules,3 times a day;CP+Shendan Sanjie group was orally treated with 6 Shendan Sanjie capsules,3 times a day. 21 d was a treatment period,and the efficacy was evaluated after 2 treat-ment periods,improvement of life quality,progression-free survival,1-year survival rate and toxicity reactions were observed. RE-SULTS:The recent effective rate,disease control rate,total improvement rate of life quality,progression-free survival and 1-year survival rate in CP+Pingxiao group and CP+Shendan Sanjie group were significantly higher than CP group,incidences of leukope-nia,thrombocytopenia,gastrointestinal tract and decreased hemoglobin were significantly lower than CP group,the differences were statistically significant(P<0.05);however,there was no significant difference between CP+Pingxiao group and CP+Shendan Sanjie group(P>0.05). CONCLUSIONS:Both Pingxiao capsule and Shendan Sanjie capsule can be combined with CP program in the treatment of NSCLC in stageⅣ,with good safety.

Children with hematological diseases usually accompanied by low autoimmune function,and repeated chemotherapy exacerbated the damage to their immune system and hematopoietic function.Those lead to high incidence of nosocomial infection,most of infection were caused by multi-drug resistant bacteria and fungi.The major infections in hematological children are the following:multi-drug resistant Escherichia coli/Klebsiella pneumonia bacteria;multi-drug resistance Pseudomonas and Acinetobacte;Methicillin-resistant coagulase negative Staphylococcus and aureus;multi-drug resistance Enterococcus faecium.This review presents updated treatment strategies from the published clinical literature and provides recommendations for clinical treatment of multi-drug resistant bacteria in children with hematonosis.

Objective To observe the preventive effect of epidural injection with low - dose of ketamine on postanesthesia shivering(PAS) undergoing percutaneous nephrolithotomy. Methods Sixty ASA Ⅰ～Ⅱ grade patients aged 35 ～ 72 years undergoing PCNL were randomly divided into kctamine group (n = 30, Epidural injection of 0.5mg/kg of ketamine) ,Control group(n = 30, Epidural injection of 10ml saline). The rate of shivering was observed and recorded during operation,and blood pressure and respiration were measured. Results The rate of shivering in ketamine group(10%) was significantly lower than that in control group(46.7%, P ＜ 0.05) ,There were no significant differences of blood pressure and respiration between two groups (P ＞ 0.05). Conclusion Epidural injection 0.5 mg/kg of ketamine on postanesthesia can prevent shivering in PCNL.

Islet amyloid polypeptide (IAPP) is an important etiologic factor for the type 2 diabetes mellitus.To investigate the biological functions and the applications of IAPP,we used text mining to explore the development of the research about IAPP biochemical reagents and test kits in this study.

Objective To investigate the expression of vascular endothelial growth factor (VEGF) in colon cancer and its relation with the microvessel density (MVD) and p53 gene. Methods The expression of VEGF, p53 gene and MVD of different region of colon cancer were studied by immunohistochemical method from 68 by surgical resected specimens. Results The positive rates of VEGF, p53 and MVD in colon cancer were significantly higher than those in peritumor and normal tissue. The expression of VEGF and p53 positively correlated with depth of invasion, lymph node metastasis, distant metastasis, vessel invasion and Dukes' stage, but their relation to the histologic types was not significant. The MVD in p53(+) ( 34.6 ?12.2 ) and VEGF(+) (31.2?12.6) tumors was significantly higher than that in p53(-) and VEGF(-) tumors (15.0?7.9; 12.7?6.3, respectively, P

Objective To explore the role of non-receptor tyrosine kinase(c-Src)in sevoflurane pretreatment for relieving myocardial ischemia-reperfusion injury.Methods By using the random number table,the healthy male Wistar rats were randomly divided into 5 groups (n=10):sham operation group (Ⅰ),ischemia-reperfusion group(Ⅱ),sevoflurane pretreatment group(Ⅲ), sevoflurane pretreatment plus dimethyl sulfoxide(DMSO,Ⅳ)and sevoflurane pretreatment plus c-Src specific inhibitor SU6656 group(Ⅴ)groups.The group Ⅲ,Ⅳ and Ⅴ were performed the sevoflurane aftertreatment before reperfusion;the group Ⅴ was in-jected by SU6656 at 5 min before reperfusion;the group Ⅳ was given the equal volume DMSO.The arterial blood sample in each group was collected at 120 min after reperfusion for detecting serum LDH level and CK-MB activity.Rats were killed for taking the heart and separating the left ventricle to calculate the area of myocardial infarctio;the expression levels of Src,phosphorylated Src (p-Src),CAT and SOD in myocardial tissue were detected in each group.Results Compared with the groupⅠ,the level of serum CK-MB and LDH activity,myocardial infarct area and p-Src/Src,CAT,SOD in the other 4 groups were increased significantly (P <0.05);comparing with the group Ⅲ,the serum CK-MB and LDH activity,myocardial infarct area and SOD,CAT,in the group Ⅱ,Ⅳ and Ⅴ were increased,however the level of p-Src/Src was decreased significantly (P <0.05).Conclusion The c-Src-reactive ox-ygen signaling pathway might mediate the role of sevoflurane pretreatment for reducing myocardial ischemia-reperfusion injury in rat.

Objective:To develop a UV optical fiber in situ process monitoring method for the dissolution behavior of five cepha-lexin solid dosage forms and compare the drug dissolution behavior of different cephalexin preparations. Methods: The dissolution of five different cephalexin preparations was on-line monitored according to the dissolution method for cephalexin tablets in Chinese Phar-macopeia (2010 edition) combined with a six channel optical fiber chemical sensor in situ dissolution monitor. Results:The dissolu-tion curves could show the drug release characteristics of different cephalexin preparations, and the five different preparations exhibited various drug release features. Conclusion:An in-situ, real time, on-line and process analysis of dissolution can be obtained by optical fiber dissolution test system automatically. The release characteristics of different preparations can be presented through dissolution curves directly, which can provide reference for the overall assessment of drug internal quality and clinical medication.

OBJECTIVE:To investigate the effects of the antihypertensive protein from Pheretima on blood pressure, angiotensinⅡ and angiotensin Ⅱ AT1 receptor in spontaneously hypertensive rats (SHR).METHODS: The dynamic change of blood pressure in SHR after singel intravenous injection of antihypertensive protein from Pheretima was observed. After intervention with antihypertensive protein from earthworm for 28 d,the levels of blood pressure, angiotensinⅡ and expression of angiotensin Ⅱ AT1 receptor in SHR were detected. RESULTS: Either single intravenous injecion or multiple dosing of the antihypertensive protein from Pheretima could significantly reduce the blood pressure in SHR (P0.05).The expression of angiotensin Ⅱ AT1 receptor in kidney of SHR model increased significanlty compared the normal control (wistar rats), but decreased after the intervention of the antihypertensive protein from Pheretima.CONCLUSION: The antihypertensive protein from Pheretima has antihypertensive effect on SHR. The mechanism may be related to the reduction of angiotensinⅡ level and lowering of the expression of a angiotensin Ⅱ AT1 receptor in kidney.
