The mental health state of the 256 fourth-year medical students of Kunming Medical College was preliminarily analyzed by requiring. The students fill in the inquiry sheets (questionare) in a question-and-answer way. The ages of these 136 male and 120 female students ranged from 19 to 23 years old, and the self-desiged 109 items of the investigation were induced into 8 aspects related to the mental health such as the outlook on life etc. The result showed that these are differences between the mental health state of the senior medical students and the traditional ideas, morality, manners of education etc. Some initial points of view were put toward.

Glucosylceramide synthase(GCS) plays an important role in ceramide metabolism and can block apoptosis signal pathway which is mediated by ceramide. Recently, studies have demonstrated that overex-pression of GCS exists in various muhidrug resistant cancer cell lines and is related to drug resistant pheno-type. A possible connection between GCS and P-gp is also suggested. Moreover,the level of GCS can be down-regulated to increase tumor cells sensitivity by chemical inhibitor and RNA interference. Thus, inhibition of ac-tivity and expression of GCS is a new mechanism of reversing muhidrug resistance.

Protracted bacterial bronchitis (PBB) is a common cause of children chronic cough,especially in those aged 1 ～ 6 years.It is defined by the presence of persistent wet cough for longer than 4 weeks,but lacks of symptoms or signs of other alternative diagnosis of chronic cough.It shows a normal or near-normal chest radiograph,a intense neutrophilia in bronchoalveolar lavage fluid(BALF),and a chronic purulent bronchitis under bronchochoscopy,and usually resolves after two-week course of appropriate oral antibiotic (usually amoxicillin-clavulanatc).So far,PBB hasn't been fully recognized by most pediatricians,and often been unrecognised or misdiagnosed as asthma.In this paper,pathogenesis,diagnosis and treatment are reviewed.

Objective To explore the protective effect of Ligustrazine on pulmonary fibrosis caused by hyperoxia in neonatal rats.Met-hods Eighty Sprague-Dawley(SD)clean neonatal rats,which were less than 12 hours old,were enrolled in this study.The neonatal rats were randomly divided into 4 groups:air-exposed control group(group A);air-exposed plus Ligustrazine-treated group(group B);hype-roxia-exposed control group(group C);hyperoxia-exposed plus Ligustrazine-treated group(group D).The neonatal rats of group B and group D were intraperitoneally injected with Ligustrazine[30 mg/(kg?d)] in solution of normal saline(NS),group A and group C were intraperitoneally given the same dose of NS.On 14th day,10 rats of each group were randomly chosen and then killed,the pulmonary pathological changes were observed by HE staining under light microscope.The area percentages of collagen fibers were measured by Masson staining and imaging analysis.The degree of pulmonary fibrosis was evaluated by the area percentages of collagen fibers and hydroxyproline content.The results were analyzed by SPSS 13.0 software.Results On the 14th day of the exposure,the histopathologic examination demonstrated broadened lung interstitium and reduced alveolar quantity and lung fibrosis were developed in group C;Ligustrazine treatment obviously alle-viated the changes of lung histomorphology.The newborn rats in group C had lower body weight compared that of with group A,B(Pa0.05).Conclusion Early use of Ligustrazine can decrease the severity of the pulmonary fibrosis of neonatal rats exposed to hyperoxia.

Calcitonin gene-related peptide (CGRP), a predominant neurotransmitter in sensory nerves, is widely distributed in central and peripheral tissues. In the cardiovascular system, besides relaxing vascular smooth muscle, CGRP protects against ischemic myocardium while inhibiting cardiac remodeling. The pharmacological effects of nitroglycerin and rutaecarpine have proved to be associated with the increase in the synthesis and release of CGRP. In gastrointestinal tissues, CGRP participates in the regulation of gastrointestinal function and has protective effects on the gastric mucosa. Rutaecar?pine, capsaicin and its derivatives can reduce gastric mucosa damage induced by a variety of factors by increasing synthesis and release of CGRP.

Vaccination in children suffering neurological diseases is a troublesome issue that people es-pecially pediatricians are reluctant to mention. Due to worrying about the emergence of adverse reactions and concerning on the heat induced seizure,doctors and parents tend to cancel or do not recommend these children to be vaccinated. Additionally,the heat sensitive seizures,such as febrile seizure( FS) ,generalized epilepsy with fe-brile seizure plus(GEFS+),Dravet syndrome account for the largest proportion of the seizure related disease and epilepsy syndrome. Their pathogenesis has been proved relating to the mutation of SCN gene of the sodium channel. For children with FS,GEFS+,and Dravet syndrome,vaccination may lead to fever,which even may bring about convulsions,but it will not result in worse prognosis.

In order to accelerate the comprehensive reform of clinical education,the Ministry of Education and the Ministry of Health decided to implement the program of excellent doctor education training plan in 2012.On the basis of the plan,taking a certain medical college as an example,on the problems such as lack of teachers,unreasonable age structure,the lack of advanced experimental technology and comprehensive talents and the lack of innovation and enterprising spirit and so on,the author puts forward some proposals from the development of experimental teaching,the teachers' personal and professional growth and the institutional and policy level,such as strengthening the foreign exchange,making learning training plan and personal development planning,establishing the evaluation system of the experiment teaching quality and opening up a variety of learning methods to improve the teachers' comprehensive ability.

OBJECTIVE:To systematically review the efficacy and safety of misoprostol combined with 10% Calcium gluco-nate injection in the treatment of postpartum hemorrhage,and provide evidence-based reference for the clinical treatment. METH-ODS:Retrieved from PubMed,EMBase,Ovid,CBM,CJFD and VIP,randomized controlled trials (RCT) about misoprostol combined with 10% Calcium gluconate injection (test group) versus conventional oxytocin in the treatment of postpartum hemor-rhage were collected. Meta-analysis was performed by using Rev Man 5.2 software after data extract and quality evaluation by Co-chrane systematic review manual 5.1.0. RESULTS:Totally 7 RCTs were enrolled,involving 1254 pregnant women. Results of Me-ta-analysis showed,compared with conventional oxytocin,misoprostol combined with 10% Calcium gluconate injection can signifi-cantly reduce 2 h postpartum hemorrhage [MD=-76.76,95%CI(-105.73,-47.79),P<0.001],24 h postpartum hemorrhage [MD=-118.28,95%CI(-167.78,-68.78),P<0.001] and the incidence of postpartum hemorrhage [OR=0.19,95%CI(0.08, 0.46),P<0.001],and shorten the 3rd delivery process [MD=-3.52,95%CI(-4.20,-2.84),P<0.001],the differences were sta-tistically significant;there was no significant difference in the intraoperative hemorrhage [MD=-61.31,95%CI(-121.98,-0.64), P=0.05] and neonatal 1 min Apgar score [MD=0.10,95%CI(-0.38,0.59),P=0.67] in 2 groups. The incidences of chest dis-tress,breathlessness and stomach discomfort in test group were significantly higher than control group [OR=18,95%CI(2.42, 133.98),P=0.005],but it was mild,and there was no significant difference in the incidence of fver,chills and nausea,vomiting, diarrhea and other adverse reactions. CONCLUSIONS:Both the efficacy and safety of misoprostol combined with 10% Calcium gluconate injection in the treatment of postpartum hemorrhage are good. Due to low quality and small-scale of included studies, more large-scale and long-term follow-up studies with strict designed are required for further validation of the conclusions.
