ObjectiveTo observe the clinical efficacy of acyclovir in treatment of children with herpes angina. Methods127 patients suffered from herpes angina were randomly divided into two groups of children,the treatment group,64 patients received the symptomatic treatment on the basis of such general use of acyclovir treatment. The control group 63 cases, received the same general treatment as treatment grounp and, intravenous ribavirin. clinical effect was observed. ResultsThe effective rate was 98.44％, of which 37 cases markedly effective in 26 cases, 1 case of invalid; the control group, the total effective rate was 82.54％, Narkedly effective in 24 cases, effective in 28cases,ineffective in 11 cases. Two groups had significant difference. ConclusionAcyclovir in treatment of children with herpes angina could rapidly control the disease,and the clinical recovery time and efficacy was better than ribavirin.

ObjectiveTo observe the treatment effects and importance of dinoprostone suppository in promoting cervical ripening during induction of labor for full-term pregnancy and nursing points. Methods92 cases of pregnancies in the obstetrics and gynecology department of our hospital from December 2009 to January 2011 were selected and randomly divided into the observation group and the control group with 46 cases in each group.The observation group was given dinoprostone suppository for induction of labor,while the control group was given induction of labor by pitocin.The curative effects of these two drugs in cervical ripening in labor induction were compared. ResultsThe curative effects of the observation group were obvious,the cervical score of the observation group 12 h after medication was obviously higher.than that before the treatment,and compared with the control group,there were significant differences.The labor time,the total production process and delivery time of the observation group were all obviously lower than those of the control group.The successful induction rate was 91.3％ in the observation group,which was obviously higher than 80.4％ of the control group. ConclusionsThe dinoprostone suppository is suitable for cervical mature during induction of labor for full-term pregnancy,and it is safe,controllable and has good effects.

Objective To find the best way to terminate early intrauterine pregnancy through comparative observation. Methods Through comparing the method of using disposable suction curettage tube to terminate early intrauterine pregnancy and medical abortion, and the method of induced abortion with traditional metal suction tube combined with local infiltration anesthesia, the complete abortion rate, intraoperative pain, blood loss and complications,etc were observed. Results Using disposable suction curettage tube to terminate early intrauterine pregnancy can result in no pain or less pain,with a bleeding time 1 to 6 days ,3.5 days on average ,both of which less than menstrual volume,with 100% complete abortion and no complications. Postoperative recovery time of period was 25 to 40 days,32.8 days on average. This method was better than medical abortion and induced abortion with local infiltration anesthesia. Conclusion Using disposable suction curettage tube to terminate early intrauterine pregnanncy did not need cervical dilation,and had advantage of light suction,less bleeding,no pain or less pain for pregnant women,no complications,rapid recovery,and was easy and safe to operate. It was the best way to terminate early intrauterine pregnancy.

Objective To study the molecular mechanism of the toxic effect for tetracycline acting on liver using toxicological microarray.Methods Utilizing the mouse toxicological microarray and animal model of tetracycline injuring BALB/c mouse liver,both of which were established by our department,we observed the gene expression profiles in different dose groups and at different time points after tetracycline treatment,and primarily analysed the function of these differentially expressed genes using Gene Ontology Consortium analysis system and hierarchical method.Results Multiple differentially expressed genes were found,and an obvious difference in the profiles was found in those treated with high-dose and low-dose tetracycline.The differentially expressed genes of all time points in high-dose group were divided to four clusters,which respectively related to the molecular mechanism of repressed enegy metabolism,enhanced protein synthesis and degradation,impared system of resisting oxidation,signal transduction genes changing to accelerate apoptosis,repressed genes associated of drug metabolism.Conclusion The analysis using toxicological microarray can offer us many clues on molecular level for studying the mechanism of the toxic effect of tetracycline acting on liver.

Objective To reduce the occurrence of undesirable catheter-related events in patients with indwelling catheter during the course of continuous chemotherapy.Methods(1)To enhance the propaganda,education and guidance to patients.(2)To standardize the nursing care operations.(3)To establish the reasonable care rules and procedures.(4)The nurses should take the daily nursing care,observations and recording work seriously.Results Through the analysis of a variety of problems occurred in patients with indwelling catheter during the course of continuous chemotherapy the nursing care experience was summed up.Conclusion Proper and effective care can reduce the occurrence of undesirable catheter-related events in patients with indwelling catheter during the course of continuous chemotherapy.

Objective To evaluate phenomenons and features of transient tricuspid regurgitation.Methods 56 cases of infant suffered severe pneumonia was examined by Doppler.Results The cardiac valves of the infant suffered severe pneumonia had normal shapes and location.48 cases with transient tricuspid regurgitation was found.The rate of occurance was 83.8%.Of these cases,most of them were in light level transient tricuspid regurgitation,a few were in medium level.The features were described as below:(1)The signal of reversed bloodstream from valve to right auricular was multicoloured.The direction of regurgitation was point to auricular septal or right auricular wall.The maximum velocity of regurgitation was 1.46～2.51M/S.(2)The transient tricuspid regurgitation had the features of reversibility.The transient tricuspid regurgitation could disappear nearly along with the recovery of severe pneumonia.Only 5 cases was transformed from medium level into light level.Conclusion The Doppler examination used in infant suffered severe pneumonia with transient tricuspid regurgitation is evidently superior to tricuspid valve auscultation,and the Doppler examination can be used to differentiate with congenital cardiac diseases.It is a useful method to evaluate the state,the variation and the curative effect of the illness.

Objective To observe the effect of integrated traditional Chinese and Western medicine and rehabilitation therapy on the recovery of neurological function in patients with acute stroke.Methods 84 patients with acute stroke were randomly selected from January 2014 to November 2016 in our hospital and were randomly divided into observation group and control group,42 cases in each group,the control group were treated with combination of traditional Chinese and Western medicine treatment,the patients in the observation group were given rehabilitation therapy,compared two groups of patients effect of treatment.Results Before treatment,there was no significant difference in FMA,BI and NIHSS scores between the two groups; After treatment,the FMA,BI score of observation group were significantly higher than the control group(P<0.05),NIHSS score was significantly lower than the control group(P<0.05); the observation group patients quality of life significantly higher than that of the control group(P<0.05).Conclusion The combination of traditional Chinese and Western medicine and rehabilitation therapy can significantly improve the patient's limb motor function and overall neurological function,effectively improve the patient's daily life ability and quality of life.

Based on data provided by the China Scientific and Technical Papers and Citations Database, an analysis was made of some bibliometric indexes of the Chinese Journal of Hospital Administration over the 2001-2004 period, including total citation frequency, impact factor, citation index, and the proportion of papers based on fund-assisted projects. The result indicates that the journal has high impact factor and total citation frequency in periodicals covered by the China Scientific and Technical Papers and Citations Database, ranking first among periodicals of basic and general medical sciences. This shows that the journal enjoys high academic status and academic impact. It is pointed out that authors of management science papers should pay more attention to cited references and that the number of papers based on fund-assisted projects should be increased so as to raise their proportion in the Chinese Journal of Hospital Administration.
