Objective:To observe the effect of acupoint injection with Neostigmine Methylsulfate at Zusanli (ST 36) on gastrointestinal function of patients after laparoscopic cholecystectomy. Methods:Totally 120 patients undergone laparoscopic cholecystectomy were randomized into an acupoint injection group, a muscular injection group, and a blank control group at 1:1:1 by random number table, 40 cases in each group. The blank control group was intervened by conventional post-operation treatment, the acupoint injection group was by acupoint injection with Neostigmine Methylsulfate 2 mL at bilateral Zusanli (ST 36) in addition to the treatment given to the blank control group, and the muscular injection group was by muscular injection with Neostigmine Methylsulfate 2 mL in addition to the treatment given to the blank control group. The two injection groups both received injection twice a day, totally for 3 d at most. The restored time of bowel sounds, initial flatulence time, defecation time and clinical efficacy were observed. Results:After treatment, there were significant differences in comparing the restored time of bowel sounds among the three groups (F=17.30,P<0.05), the acupoint injection group and muscular injection group were significantly different from the blank control group (P<0.05), and there was a significant difference between the acupoint injection group and muscular injection group (P<0.05); there were significant differences in comparing the initial flatulence time among the three groups (F=19.12,P<0.05), and the acupoint injection group was significantly different from the muscular injection group and the blank control group (P<0.05); there were significant differences in comparing the initial defecation time among the three groups (χ2=21.23,P<0.05), while the difference between the acupoint injection group and muscular injection group was statistically insignificant (P>0.05). The total effective rate was 87.5% in the acupoint injection group, versus 72.5% in the muscular injection group and 60.0% in the blank control group, and there were significant differences among the three groups (P<0.05). Conclusion:Acupoint injection with Neostigmine Methylsulfate at Zusanli (ST 36) can shorten the restored time of bowel sounds and flatulence time in patients undergone laparoscopic cholecystectomy, and the efficacy is more significant compared to muscular injection with Neostigmine Methylsulfate.

C. Conclusion Adequate hemodilution can attenuate the lung injury induced by I/R. The protective effect is better if hemodilution is performed before I/R.

OBJECTIVE: To investigate the characteristics and regularity of antineoplastic medicine-induced adverse drug reaction (ADR) occurred in our hospital. METHODS: 162 antineoplastic medicine-induced ADR cases reported in our hospital from 2005 to 2008 were analyzed statistically in respect of patients’age and sex, categories of drugs, route of administration, drug combination,organs and systems involved in ADR and clinical manifestation, etc. RESULTS: Of the total 162 ADR cases, proportion of men was similar to women. 68 cases (41.98%) were old persons aged older than 60. 123 cases(75.93%) were single use of drugs, 39 cases(24.07%) were combined use of drugs. 39.51% of ADR cases were induced by antineoplastic medicine made from plants and took up the first place in terms of incidence of ADR. 36.42% of ADR cases dominantly manifested as lesion of skin and its appendants. CONCLUSION: ADR monitoring of antineoplastic medicine should be strengthened to ensure rational and standardized use of antineoplastic medicine, avoid or reduce the occurrence of severe ADR.

Objective To explore the effects of quetiapine combined with sertraline in the treatment of schizophrenia patients with depressive symptoms.Methods 86 patients of convalescence of schizophrenia with depression symptoms were randomly divided into quetiapine combined with sertraline group(observation group) and quetiapine group(control group).The treatment course was 8 weeks.Before and after treatment,the positive and negative symptoms scale (PANSS) and Hamilton depression scale (HAMD) were assessed in the two groups.The curative effect of quetiapine combined with sertraline on the schizophrenia patients with depression symptoms was explored.Results Pre-treatment,there were no differences in the two groups on PANSS score (t =-0.432,P ＞ 0.05),HAMD score (t =0.424,P ＞ 0.05).Post-treatment,there were significant differences between the two groups in PANSS score (t =18.780,P ＜ 0.05;t =12.256,P ＜ 0.05) and HAMD score (t =6.542,P ＜ 0.05;t =4.107,P ＜0.05).There were significant differences between the two groups in HAMD score (t =6.612,P ＜0.05).Conclusion Quetiapine can significantly improve the effects of positive and negative symptoms and depressive symptoms of schizophrenia patients with depression symptoms.Quetiapine combined with sertraline can improve the depressive symptoms of schizophrenia better compared with quetiapine.

OBJECTIVE:To observe the clinical efficacy and safety of amlodipine besylate combined with lisinopril and hydro-chlorothiazide,atorvastatin in the treatment of severe primary hypertension complicating with carotid atherosclerosis. METHODS:90 patients with severe primary hypertension complicating with carotid atherosclerosis were divided into control group (45 cases) and observation group(45 cases)according to random lottery form. Both groups were given Atorvastatin calcium tablet 20 mg/time orally,qd;control group was additionally given Amlodipine besylate tablet 5 mg/time orally,qd;observation group was additional-ly given Lisinopril and hydrochlorothiazide tablet 10 mg/time orally,qd,on the basis of control group. Both groups were treated for 8 weeks. Clinical efficacies of 2 groups were compared as well as blood pressure level,IMT,PV of carotid atherosclerosis, hs-CRP,TNF-α before and after treatment. The occurrence of ADR was recorded. RESULTS:Total response rate of observation group was significantly higher than that of control group,with statistical significance (P<0.05). Before treatment,there were no significant differences in SBP,DBP,IMT,PV,hs-CRP and TNF-α level(P>0.05). After treatment,the levels of SBP,DBP, IMT,PV,hs-CRP and TNF-α level in 2 groups were significantly lower than before;the observation group was significantly lower than the control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR be-tween 2 groups (P>0.05). CONCLUSIONS:Amlodipine besylate combined with lisinopril and hydrochlorothiazide,atorvastatin in the treatment of primary hypertension complicating with carotid atherosclerosis can effectively control the blood pressure level, delay the progression process of carotid atherosclerosis,reduce the inflammatory reaction degree,but dose not increase the occur-rence of ADR with good safety.

RNA interference(RNAi),the first method of choice to suppress gene expression in vitro,is a conserved biologic response to double-stranded RNA that resulted in the sequence-specific silencing of target gene expression.Recently,more than 100 literatures reported synthetic small interfering RNAs in mammals.These reports demonstrated that RNAi is also a powerful tool for in vivo research and may become an effective therapeutic tool.This paper reviews the influencing factors and experimental design of in vivo use of RNAi.
