Objective:To explore the infuence of calf spleen extractive injection combined with chemotherapy on immune function of the patients after colorectal carcinoma. Methods:Totally 128 cases of postoperative colorectal carcinoma patients were randomly di-vided into two groups with 64 ones in each. The control group only received FOLFOX 4 regimen, while the study group received calf spleen extractive injection additionally from the first day to the tenth day, 10ml, ivd, and 14-day was one cycle. After 4 weeks, im-mune function, peripheral blood leukocytes ( WBC) , hemoglobin ( Hb) and platelet ( Plt) in the two groups were compared, and the adverse reactions were evaluated as well. Results: After the treatment, CD3 +, CD4 +, CD8 + and CD4/CD8 were increased in the study groups, and those in the study group were much higher than those in the control group (P<0. 05). After the treatment, there were no significant changes in WBC, Plt and Hb in the two groups (P>0. 05), while WBC and Plt in the study group were higher than those in the control group (P<0. 05). The incidence of adverse reactions in the study group was lower than that in the control group (P<0. 05). Conclusion:Calf spleen extractive injection combined with chemotherapy not only can increase the immune func-tion, but also alleviate myelosuppression and gastrointestinal toxicity in the treatment of postoperative colorectal carcinoma patients.

OBJECTIVE To investigate the pertinency between acute physiology and chronic health evaluation Ⅱ scores(APACHEⅡ)and nosocomial infection.METHODS The clinical data from 1 007 ICU patients were evaluated with APACHEⅡ scores system,and made a prospective survey of nosocomial infection.RESULTS Along with the increase in APACHEⅡ scores,nosocomial infection rate and mortality showed rising trend and they were in linear relationship.CONCLUSIONS APACHEⅡ scores system not only can appraise the degrees of severity of illness,evaluate medical treatment,and estimate the prognosis,but also forecast nosocomial infection.

Objective To investigate the changes of uveoscleral pathway by an I1 receptor agonist,moxonidine,and with pretreatment of antagonists topical administration,and to study the mechanism that moxonidine improves uveoscleral outflow.Methods Moxonidine was administered unilaterally and topically to rabbits and with pretreatment of the antagonists,namely,prazosin,yohimbine and efaroxan.FITC-BSA,a tracer agent,was injected into the anterior chamber after moxonidine treatment or with pretreatment of the antagonists.Frozen sections were undertaken at different time points between 2 to 10 h.Fluorescence intensity was observed in the sites of uveoscleral pathway in the sections by fluorescence microscopy.Results Bilateral fluorescence intensity treated with moxonidine was more intense than that with placebo,and the most intense regions of fluorescence were ciliary body and superchoroidal space.Fluorescence intensity by prazosin pretreatment was not significantly different compared to that by moxonidine,while yohimbine and efaroxan pretreatment decreased the intensity compared with moxonidine(P

AIM:To explore the protective effects of riboflavin on the kidney in streptozotocin (STZ)-induced diabetic rats.METHODS:Male Sprague-Dawley rats were randomly divided into 3 groups:normal control group,diabetic model group and riboflavin-treated group.Diabetes was induced by a single injection of STZ (dissolved in 0.01 mol/L citrate buffer,pH 4.5,65 mg/kg,ip) in rats.The biochemical methods were used to measure the contents of urine protein and malondialdehyde in the kidney,and the activities of superoxide dismutase (SOD) and catalase (CAT) in serum and renal tissues.Furthermore,the protein expression of TGF-?1 and plasminogen activator inhibitor-1(PAI-1) in renal cortex was detected by Western blotting.The morphological changes of renal tissue were observed under microscope.RESULTS:Compared to the diabetic model group,riboflavin significantly increased the activities of SOD and CAT (P

Objective To explore the effect of Vitamin K1(Vit K1), fresh frozen plasma (plasma) andcryoprecipitate on prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen original(Fbg), thrombin time (TT) of newborns with different gestational ages. Methods The serum of 1,134 newbornsfrom The Third Affiliated Hospital of Guangzhou Medical University was collected from February 2009 to September2012. All newborns had been divided into four groups (according to the gestational age of 28-31+6 weeks, 32-33+6weeks, 34-36+6 weeks and gestational age≥37 weeks).The effect of various interventions (Vit K1, Vit K1+plasmaand Vit K1+cryoprecipitate) on PT, APTT, Fbg, and TT had been recorded. Results (1)The PT and APTT ofeach group with the interventions of Vit k1 were significantly improved (P < 0.05). (2)The PT, APTT, Fbg and TTof each group with the interventions of Vit k1 combined with plasma were significantly improved (P < 0.05). (3)ThePT, APTT and Fbg of each group with the interventions of Vit k1 combined with cryoprecipitate were significantlyimproved (P < 0.05). (4)With Vit k1 combined with plasma, PT and APTT were mostly improved and Fbg wasimproved mostly with Vit k1 combined with cryoprecipitate. Conclusion Vitamin K1, fresh frozen plasma andcryoprecipitate can effectively improvedin the coagulation index of newborns with different gestational ages.
