Bibliographic database of TCM periodicals was used as data source and hand-foot-mouth disease was used as subject for searching. Based on periodicals resource of hand-foot-mouth disease in this database, we analyzed the current situation of preventing and treating hand-foot-mouth disease by bibliometrics method, providing references for scientific studies.

By analyzing the current ineffective condition of college English teaching,the article puts forward practical measures in terms of purpose of English learning,classroom teaching,and the creation of after class language environment,aiming to promote the efficiency of college English teaching.

AIM:To compare the difference between diopter of refration measured after cycloplegic mydriasis with retinoscopy and hand-held autorefractor so as to explore the feasibility of using hand - held autorefractor for refraction screening in cadet candidates.
METHODS:Respectively using hand-held autorefractor and streak retinoscope to do optometry examination in 317 cadet candidates students ( 634 eyes ) after mydriasis. Main index of refraction values ( spherical, cylindrical mirror degree and axial) were analyzed by difference test and correlation analysis. And the elimination rate was comparatively analyzed.
RESULTS: Diopters of sphere and cyclic refraction measured by hand-held autorefration were significantly higher than those by retinoscopy ( P< 0. 05 ), but the correction analysis showed that there was high correlation (r=0. 733, 0. 694), axial of refration measured by these two methods were non - significant ( P > 0. 05 ). The disqualifying rate using autorefraction was much higher than that using retinoscopy. It was easy to be wrongly eliminated.
CONCLUSION:Because of the high correlation between diopters of autorefraction measured by retinascopy and autorefractor, autorefraction has application value in refraction screening in cadet candidates with normal vision.

Objective To explore the consistency between preoperative clinical TNM stage and postoperative pathological TNM stage of gastric cancer and look for the underlying reason.Methods Sixty-four patients of gastric cancer with complete clinical data from December 2010 to December 2011 in Gansu Provincial Hospital were enrolled into this study.All cases were performed postoperative pathological TNM staging according to the TNM stage criteria of gastric cancer from JGCA(the 14th edition,2010),and the results were compared with preoperative TNM staging,then we studied the consistency of T staging,N staging and M staging using SPSS 18.0.Results The Kappa value from T staging of preoperative and postoperative was 0.729,showing a good consistency.The N stage' s consistency was lower,Kappa value being only 0.216.For M staging,Kappa value 0.743,having a good consistency.Conclusions According to the General Rules for Gastric Cancer Treatment,a accurate TNM staging and individual treatment plan can be made for gastric cancer patients in clinic.But the overestimate and underestimate still existed,especially in N staging.Therefore,making a accurate judgment for N staging according to all kinds of preoperative clinical data and images is the key to improvement of preoperative TNM staging accuracy and treatment.

Objective To investigate the autonomic modulation and influence during myocardial ischemia based on analysis on heart rate dynamics with heart rate variability(HRV). Methods From 13 free download ECG records in long-term ST-T(LTST)database, 193 ischemia episodes were extracted for analysis, and 5 min intervals before and after each selected isehemia episode were selected as control ones. Using symbolic dynamic analysis method, the indexes during different stages were calculated. The repeated measurement analysis of variance was introduced for statistic test. And the distribution of autonomic reflex mode to isehemia duration was analyzed by linear fitting. Results Symbolic analysis detected an increase in the percentage of non-varlable patterns (0 V%) and a decrease in the percentage of very variable patterns(2 UV%), indicating a more sympathetic predominance compared with the baseline. But the trend of the shift in autonomic balance towards sympathetic predominance reduced with the extension of ischemic duration, suggesting a possible protection for heart. Conclusion Symbolic dynamic analysis is capable of identifying changes in autonomic modulation and seems appropriate for elucidating the neural pathophysiological mechanisms occurring in myocardial ischemic episodes.

[Objective]Through the clinical investigation of the conversative treatment of undisplaced femoral necks,to analyze the occurrence of secondary displacement and femoral head necrosis.[Method]The medical records of 216 patients with undisplaced femoral neck fractures who were primarily treated conservatively from January,2000 to January,2004 were analyzed.Among that,186 cases is in accordance with the selected standard,which were consisted of 82 men and 104 women.(the average age 67.5).One hundred and forty-one fractures were given to bed rest in rotation-proof shoes,and walking on the crutches was followed after four weeks.Forty-five patients began to get out of bed with double crutches on the third day.When displacement happened,the operation was carried out.Once X-rays showed the fracture line unclearly,it is considered as bone healing.The early stage of femoral head necrosis was defined by sclerotic region or cyst in the femoral head.[Result]Sixty-eight fractures(36.6%) united and secondary considered displacement occurred in 118 cases(63.4%); the average time was 16 days (2～68 d) after injury when the displacement is found.In all primary healing patients,femoral head necrosis rate was 25%.The discovery time of necrosis was between 4 and 18 months,the most was 36 cases in the interval of 6 to 12 months.As for patients of secondary displacement,92 for closed reduction and hollow screws fixation,and the head necrosis happened in 55 patients(59.8%).The discovery time was from 4 to 18 months,the most in 6 to 12 months was 36 cases.The operation of open reduction and internal fixation with hollow screws was in 26 cases,73% of necrosis rate for it.The time was range from 3 to 12 months,11 case was the most in the period of 3 to 6 months.[Conclusion]Undispalced femoral neck fractures treated conservatively bear higher risk of secondary displacement and femoral head necrosis.In addition with more mortality and general complications,we therefore recommend primary operative stabilization of undisplaced femoral neck fractures.

Objective:Small bowel IRI models in rats were established to explore the effect of glutamine enriched parenteral nutrition on mucosal barrier,and to discuss the probable mechanisms.Methods:Thirty Wistar rats were randomly assigned into 3 groups:The control group(N group,n=10) ,conducted fictitious operation and fed with common forage,TPN group(n=10) and TPN+Glu group(n=10) .The morphous of mucous,serum and intestinal mucosal Gln concentration,levels of D-lactate,endotoxin,TNF-?,IL-6,HO-1 positive ratio and HO-1 mRNA were detected.Results:Glutamine obviously improved the structure of intestinal mucosal and decreased the expressions of D-lactate,endotoxin,TNF-?and IL-6.And enhanced the expressions of HO-1 mRNA and HO-1.Conclusion:Glutamine enriched parenteral nutrition can alleviate small intestinal IRI and inflammatory reaction and enhance the HO-1 and HO-1 mRNA expressions.HO-1 and its metabolin's anti-oxygen,anti-apoptosis,anti-inflammator action may be the mechanism of the protective action of Gln on mucosal barrier of small bowel.

Parkinson disease(PD) is a degenerative disorder characterized by the loss of midbrain dopamine (DA) neurons. Recently it has been demonstrated that ES cells can differentiate into dopaminergic neurons in vitro and is a potentiol item for transplantation. In this paper we reviewed clinical study in treating Parkinson disease、methods and mechanisms of ES cells differentiation into dopaminergic neurons in vitro and progress of its application.
