AlM:To compare the functional and cosmetic effects of two different surgical techniques for congenital ptosis.
METHODS: The patients were divided into four groups according to the operation method: Patients undertook bilateral fascial suspension surgery as Group A ( 42 eyes of 21 cases ); Patients undertook bilateral levator muscle shortening surgery as Group B ( 38 eyes of 19 cases );Patients undertook unilateral fascial suspension surgery as Group C ( 24 eyes of 24 cases ); Patients undertook unilateral levator muscle shortening surgery as Group D (29 eyes of 29 cases). Each group patients were followed for postoperative function and appearance effect.
RESULTS: 1 ) Early postoperative of two operation function success rate was up to 100%, the function of levator muscle shortening surgery was 97. 01% in the late postoperative, was higher than bilateral fascial suspension surgery (87. 88%), with statistical difference in both surgerys (P<0. 05). 2) Appearance effect of two kinds of operation method in early postoperative had no statistical difference (P >0. 05); ln the late postoperative, the mean grades for “Lid Contour” and “Lid Crease” of Group B were better than that of Group A (P<0. 01). While the mean grades for “Lid Contour”, “Symmetry of Lid Height” and “Lid Crease” of Group D were similarly better than that of Group C (P<0. 01).
CONCLUSlON: Two kinds of operation method have good effects on the treatment of congenital ptosis. ln terms of cosmetic effect, levator muscle shortening surgery is better.

Objectives To understand the status of wild feces distribution and pollution in schistosomiasis endemic areas in Yunnan Province. Methods According to the distribution of Oncomelania hupensis snails and characteristics of human and ani-mal activities in recent five years 6 schistosomiasis endemic villages in Weishan Nanjian and Midu counties 2 villages each county were selected as the investigated areas and more than 4 hm2 area with snails around each village were investigated for the types and densities of wild feces. The schistosome infested feces was detected with the hatching method. Results Totally 63 hm2 were investigated and 420 wild feces were found in all kinds of environments. The densities of wild feces were 0.066 7 piles/100 m2 and the densities of wild feces of the road and the hillside were the highest 0.098 7 piles/100 m2 and 0.088 0 piles/100 m2 respectively . Totally 260 fresh wild feces were collected including the feces of human being cattle horse dog sheep and pig and the feces of cattle and dog was the most 37.38%and 30.71% respectively . No schistosome positive feces was found. Conclusions There are a lot of wild feces in snail areas in Yunnan Province and the risk of schistosomiasis transmission is still high. Therefore we should strengthen the banning grazing measures and the investigation of dogs.

Objective: To investigate and analyze the KAP situation for Uv occupational injuries in Xi′an physical education teachers and provide scientific basis for the protection .Methods:Scale and questionnaire are used to survey 1200 people , using a questionnaire method to Xi′an sports teachers′occupational injuries is ultravio-let ray KAP investigation.Results:Respondents had a history of sunburn (21.5%), worked as a certified check the skin accounts for 5.1%;Think long-term outdoor ultraviolet harm to the skin (34.1%), 58.9%take protec-tive measures, can correct understanding on the Uv 3.2%; The purpose of protective measures , 43.9% of re-spondents take measures the purpose is to prevent tanning rather than prevent sunburn .Conclusions:Physical edu-cation teachers as a special outdoor work group , the overall Uv occupational injuries protection knowledge was low , from the perspective of the biopsychosocial medical model should be based on the principle of health ethics , it should strengthen the propaganda of knowledge of Uv occupational injury protection , and actively take appropriate intervention measures .

Malignant hyperthermia is a well-recognized syndrome of uncertain etiology. The confusing facts are: the variety and different nature of the triggering agents, the variation in time of onset of rigidity and fever coupled with a variation in response to succinylcholine, the lack of family history in some patients, and its occurence in some who have had previously normal general anesthetics. A case is a 23 year old relatively healthy male patient in whom subtotal gastrectomy was performed under N2O-O2-ether and gallamine anesthesia with induction after pentothal sodium and succinylcholine. This was complicated by an abrupt, high rise in body temperature, muscle rigidity, flushing with peripheral cyanosis, disseminated intravascular coagulation and hyperpnea 40 minutes after induction. He died 3 hours after cessation of anesthesia without effective response to any active antipyretic therapy. The etiologic factors, incidence, clinical feature, prevention, treatment and prognosis of malignant hyperthermia are discussed.

The study reports the detection of neuroprotective effect of 10 kinds of coumarin derivatives and explores their possible mechanism. MTT method was used to screen the neuroprotective effect of 10 coumarin derivatives on neurotoxic agents (Aβ25-35 and rotenone) or OGD (oxygen-glucose deprivation). A compound with better protective effect was obtained. Then the effect of this compound on neurotoxic agents on PC12 was detected by the morphological observation. Furthermore, the effect of compound 3 on microglia with lipopolysaccharide (LPS) induced inflammation was detected. And the inflammatory factor was tested. Finally, direct free radical scavenging ability was detected. Compound 3 was found to be the best compound through three neurons toxic models. Not only compound 3 ameliorated cell viability reduced by three neurons toxic models, but also significantly inhibited the production of inflammatory factor (TNF-α and IL-1β). And its free radical scavenging ability is very good, especially the effect on superoxide anion, which is comparable with vitamin C. The significant scavenging effect of compound 3 on superoxide anion might be the mechanism of the neuroprotection. Compound 3 as a potential neural cell protective agent merits further investigation.

Objective To evaluate the effectiveness of clinical rotation training in pain department for general practitioner.Methods Totally 31 general practitioners of 3 years program in the First Affiliated Hospital of Chongqing Medical University were involved in clinical rotation training in pain department form August 2008 to December 2011.Training lasted for one month.Clinical rotation training in pain department was conducted for general practitioners by studying rules and regulations,treatment methods,imaging data and clinical practice.Evaluation was made according to the treatment,theoretical knowledge,interpersonal skill and professional competency of general practitioners.Measurement data were expressed as mean ± standard deviation ((-x) ± s) while enumeration data were expressed as rate.Descriptive analysis of the data was used.Results Average total number of patients managed by 31 general practitioners was (15 ± 2),average total number of disease species was (5 ±2),average number of case discussion and small lecture participated was 1 ～2,average number of nerve block participated as assistant was (40 ± 5) and average number of minimally invasive surgery visited and studied was (2 ± 2).Residency duties were skillfully completed and assessment score was (85 ± 4.50).Conclusions Through clinical rotation training,general practitioners can understand common disease diagnosis and treatment category; familiarize clinical evaluation methods and master standards of diagnosis and treatment in pain department.Meanwhile,they would learn doctor-patient communication to establish a good therapeutic relationship with patients.

Objective To investigate the drug resistance genes of extended-spectrum beta- lactamase-producing bacteria in 49 strains.Methods Extended-spectrum ?-lactamase -producing strains were detected by the disc diffusion test.The techniques of polymerase chain reaction,sequence analysis, pulsed-field gel electrophoresis were used to analyze the genotype and homology of extended-spectrum ?- lactamase-producing strains.Results The incidence of ESBL-producing strains from E.coli,K pneumoniae,K oxytoca,was 20% in 2000,and 40% in 2003.Among the 49 ESBLs producers the most common genotype was CTX-M-14( n=33).The others were CTX-M-3,CTX-M-9,CTX-M-12,CTX-M-15, CTX-M-24 and SHVSa.Both two CTX-M subtypes,CTX-M-3 and CTX-M-14,were detected in one strain. However,4 ESBL-producing strains confirmed by phenotype remained untyped.The results showed that the ESBLs producers were not closely related,except for two strains of E.coli and two strains of K.pneumoniae which were homgenic respectively.Concolusions The incidence of ESBL-producing strains increases with years.The most common genotype of ESBLs is CTX-M.There is no evidence for epidemiologic spread of ESBL-producers by pulsed-field gel electrophoresis.
