Objective To investigate the clinical and etiologic characteristics and drug-resistance features of ventilator-associated pneumonia(VAP)in neonatal intensive care unit.Methods A retrospective study was conducted in 712 newborns with VAP who were admitted to the NICU from January 2007 to December 2010 and had received mechanical ventilation.The pathogenic bacteria spectrum of hospital infection were statistically analyzed.Results VAP was occurred in 69 out of 712 newborns with mechanical ventilation (incidence rate of 9.7％).The top four pathogens were saccharomyces albicans(39.2％),stenotrophomonas maltophilia(20.3％),staphylococcus epidermidis(13.5％)and klebsiella pneumoniae(9.5％),respectively.Conclusion Implementing strict measures to control the nosocomial infection can significantly reduce the incidence of VAP.Saccharomyces albicans,stenotrophomonas maltophilia,staphylococcus epidermidis and klebsiella pneumoniae were the pathogens most commonly involved.

[Objective]To investigate the effects of the seed extract of Clausena lansium,N-methyl-N-cis-styryl-cinnamamide,on the penicillin-induced epilepsy in rats.[Methods]Thirty-two Sprague-Dawely rata were randomly divided into four groups with 8 rats in each group:normal control(20 mL/L Tween 80+Normal Saline),model control(20 mL/L Tween 80+Penicillin),low dose treatment(Cinnamamide 75 mg/kg+Penicillin),hish dose treatment(Cinnamamide 150 mg/kg+Penicillin).The epilepsy rat model was established by localized intracortical injections of penicillin.The effects of pretreatments of the rats with N-methyl-N-cis-styryl-cinnamamide(intraperitoneal injection,ip)on the penicillin-induced seizure activities and the epileptiform discharges recorded by electrocorticogram(ECoG)were observed.[Results]The penicillin-induced seizure was significantly lightened in both the pretreatment groups(75 and 150 mg/kg N-methyl-N-cis-styryl-cinnamamide),compared with the model group.N-methyl-N-cis-styryl-cinnamamide(75 and 150 mg/kg)could significantly prolonged the latency of epileptiform activities,shorten the duration of epileptiform discharges and decreased the mean spike frequency in the late stage(P＜0.05 or P＜0.01).However,there was no significant difference in the highest value or the lowest value of the epileptiform waves between the model and cinnamamide treatment groups.[Conclusion]The seed extract of Clansena lansium,N-methyl-N-cis-styryl-cinnamamide,can significantly inhibit the seizure and epileptiform discharges caused by penicillin-localized injections in the cortex of rats,suggesting that the natural substance has an anticonvulsive function.

Objective To evaluate the effect of health education on preventing birth defects in community in terms of knowledge, attitude and practice (KAP) for married women in reproductive age. Method A self-designed general information form and a questionnaire on KAP of married women′s preventing birth defects were used to investigate the KAP among 300 married nulliparous women. Result The average rate of cognitive knowledge of birth defects was 60.8%, the average rate of cognitive behaviors was 59.2%, and the average rate of cognitive attitude was 67.4%. Conclusion In order to reduce the rate of birth defects and improve the quality of births, we should implement three-level prevention education system, enrich the health education methods to enhance the knowledge, attitude and behavior of married women.

Objective To explore the surgical methods in the treatment of carotid aneurysms. Methods A retros-pective analysis was made on the operations and results in 21 cases with 24 carotid aneurysms. Of the 24 carotid aneurysms, 18 were true and 6 false aneurysms. Nineteen cases underwent various operations including emergency operation in 3 cases. Carotid shunting device was used in 3 cases during operation. Results 2 cases were re-operated because of the recurrence of aneurysm,and 17 cases had satisfactory outcome without complications.None died in this series in perioperative period.

OBJECTIVETo compare the clinical effects between ginger-partition moxibustion combined with glucocorticoid and simple oral glucocorticoid for thyreoitis at subacute stage.

METHODSEighty-one patients were randomly divided into an observation group (41 cases) and a control group (40 cases). In the observation group, ginger-partition moxibustion and hormone were applied. Moxa cones were used at local ashi points, Zusanli (ST 36), Guanyuan (CV 4) and Qihai (CV 6), six cones every point, once every other day and three times a week. Besides, 24 mg methylprednisolone tablets were adopted orally every day, and in two weeks the dose was 16 mg/d, in four weeks 8 mg/d, in six weeks 4 mg/d; all the patients were observed for 8 week. In the control group, simple methylprednisolone was prescribed orally, and the dose, the usage and treatment time were the same as those in the observation group. Erythrocyte sedimentation rate (ESR), triiodothyronine (T3), thyroxin (T4) and ultra-sensitive thyroid stimulating hormone (TSH) before and after treatment were observed in the two groups, as well as fever, the pain of thyroid gland, the regression time of swelling and adverse reaction.

RESULTSThe time of thyroid gland pain relieved of the observation group was earlier than that of the control group [(3.07 ± 0.78) days vs (3.62 ± 0.92) days, P < 0.05]. After treatment, T3, T4 and ESR were declined apparently (all P < 0.01), and TSH was obviously increased in the two groups (both P < 0.01). After 2-week treatment, ESR in the observation group was lower than that in the control group (P < 0.05). After 4-week treatment, T3, T4, TSH and ESR in the observation group were better than those in the control group (all P < 0.05). After 8 weeks, all indices in the observation group were superior to those in the control group, without statistical significance between the two groups (all P > 0.05). The effects of the observation group in 2 weeks, 4 weeks and 8 weeks were better than those in the control group (all P < 0.05). The cured course was shorter in the observation group than that in the control group (P < 0.05). The adverse reaction rate in the observation group was lower than that in the control group [4.9% (2/41) vs 22.5% (9/40), P < 0.05]. Three months later after treatment, the cured patients were followed. There was no recrudescence in the observation group and three patients caught the disease again in the control group, but there was no statistical significance between the two groups (P > 0.05).

CONCLUSIONGinger-partition moxibustion combined with glucocorticoid achieves better effect than simple oral glucocorticoid for thyreoitis at subacute stage, and the adverse reaction is less, which presents the clinical advantages of the integration of Chinese and western medicine.
