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.

Gram-negative bacteria are the common pathogens causing nosocomial infections.The drug resistance of gram-negative bacteria has become increasingly serious in last two decades.Carbapenems were once considered as the last line of defense against serious infections of gram-negative pathogens.As carbapenemase-producing strains are spreading, the incidence of infections caused by carbapenem-resistant isolates is increasing worldwide.The pathogens are usually multiple drug resistant strains or extensively drug resistant strains, and effective treatment options are limited, even there are no more drugs in certain conditions.This article focuses on appropriate antibiotics and therapeutic strategies for effective control of infections with carbapenem-resistant gram-negative pathogens.

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.

ObjectiveTo compare the differences in stroke subtype classification between ASCO and modified TOAST.MethodsAll 425 first-ever ischemic stroke patients were recruited and classified into different stroke subtypes according to the ASCO and modified TOAST criteria.Results Comparing ASCO grade 1 with modified TOAST,more patients were classified as atherosclerosis (60.2％ vs 57.9％ ; x2 =2.68,P=0.132) and fewer as small artery disease and cardiac disease subtype (13.4％ vs 14.8％ and 8.5％ vs 8.7％ ; x2 =1.30 and 0.00,P =0.238 and 1.000,respectively).ASCO grade 1 did not reduce the proportion of cause undetermined patients compared with modified TOAST ( 15.5％ vs 16.2％ ; x2 =0.09,P =0.795 ). Agreement was showed in every subtype categories between the two approaches.Agreement for atherosclerotic cause and small artery disease was very good ( all κ over 0.81 ),and for the cardiac disease subtype was good (κ: 0.61-0.80). Conclusion Agreement can be found in every subtype categories between ASCO and modified TOAST classification.ASCO grade 1 does not reduce the proportion of cause undetermined cases compared with modified TOAST,but the subtype categories characteristics of the two approaches should be considered in practice.

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.
