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.

Background Cataract with preexisted dry eye is a common eye disease.It is speculated that preservative-free artificial tears can inhibit inflammatory procedure,prevent postoperative eye infections and reduce dry eye symptoms.However,relevant literature is rare up to now.Objective This study was to evaluate and compare the therapeutic effects between preservative-free or preservative sodium hyaluronate combined with fluorometholone eyedrops for cataract with dry-eye.Methods A randomized controlled single-blind clinical study was performed.Sixty patients with dry-eye syndrome who was going to receive surgery for cataract removal were enrolled in Yuhuangding Hospital from January to December 2015 under the informed consent.The patients were randomly divided into the test group and control group.Preservative-free or preservative 0.1％ sodium hyaluronate combined with 0.1％ fluorometholone eye drops were topically administered in the eyes of the test group and control group,respectively.Ocular Surface Disease Index (OSDI) score,breakup time of tearfilm (BUT),Schirmer Ⅰ test (S I t),corneal fluorescein staining,impression cytology,goblet cell density and the concentrations of interleukin (IL)-1β,tumor necrosis factor (TNF)-α,catalase (CAT),superoxide dismutase 2 (SOD2) in tears were evaluated and compared.Results There were significant differences in gender,ages,OSDI scores,BUT,S I t value,corneal fluorescein staining scores,impression cytology findings,and goblet cell density between the two groups (all at P＞0.05).OSDI,corneal fluorescein staining scores and imprint cellular level were evidently reduced,and BUT,S I t values and goblet cell density were significantly increased 1 month and 2 months after operation in comparison with the baseline values in the test group (F =13.058,8.027,3.755,21.652,70.962,92.354,all at P ＜ 0.05).The concentrations of IL-1β and TNF-α in tears of the test group were significantly lower,and CAT and SOD2 in the tears of the test group were significantly higher than those in the control group 1 month and 2 months after operation (F=18.731,9.070,15.357,351.359,all at P＞0.05).Conclusions 0.1％ preservative-free sodium hyaluronate combined with 0.1％ fluorometholone eyedrops can relieve the symptoms and signs of dry-eyes following cataract surgery by playing antiinflammatory and antioxidant effects.

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.

Purpose: To observe the curative effect of acupuncture on female climacteric syndrome.Methods: Guanyuan (CV 4), Zhongji (CV 3), Zigong (Ex-CA 1), and Sanyinjiao (SP 6) were selected as main acupoints to treat 30 cases of female climacteric syndrome according to TCM principle of aiming mainly at the kidney in the treatment of this disease. Results: The total effective rate from acupuncture treatment of this disease was 90%. It was found in the patients that serum endocrine hormones changed significantly after acupuncture as compared with before it (P＜0.05). Conclusion: It is preliminarily considered that acupuncture has a comprehensive regulating effect on neuroendocrine system and can restore the dysfunctional vegetative nervous and endocrine systems to a stable state,removing or reliving various clinical symptoms in women's climacteric.

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.
