OBJECTIVETo compare the efficacy between eccentric fixation and internal fixation for treatment of intertrochanteric fractures of femur,to provide a theoretical basis for the selection of the treatment method of the intertrochanteric fractures of femur.

METHODSFrom February 2007 to January 2010,82 patients with femoral intertrochanteric fracture were treated by internal fixation including 39 cases of eccentric fixation involving 23 males and 6 females, aged from 41 to 81 years old with an average of (62.68±10.69), using the DHS or proximal femoral locking plate; 43 cases of intramedullary fixation involving 15 males, 28 females,aged from 43 to 78 years old with an average of (62.60±8.37),using PFN or PFNA fixed. The surgical incision length, operative time, blood loss and postoperative Harris score between two groups were compared.

RESULTSThe wound of two groups were primary healing without operative complications. All cases received follow-up for an average time of 18.3 months (12 to 28 months). The incision length, operative time and blood loss had a statistically significant difference between two groups (P<0.05). Harris scores of hip joint function at 1 month after operation had statistically significant difference between two groups (P<0.05), and Harris scores at 12 months after operation had no statistical significance difference between two groups. The rate of excellent and good was 89.7% in eccentric fixation group and 90.7% in intramedullary fixation group,the difference was not statistically significant (t=0.0613, P>0.05). In eccentric fixation group, there was 1 case of fracture nonunion with DHS loose and ensuing hip varus deformity. In intramedullary nail fixation group, there was no anti-rotation out,distal intramedullary nail of femoral refracture occurred in 1 case.

CONCLUSIONTwo treatment methods for the treatment of femoral fractures had a good therapeutic effect,but the intramedullary fixation had shorter operative time and less blood loss than the eccentric fixation,it prior to apply to osteoporosis and unstable femoral intertrochanteric fractures.

AIM To investigate the exact subtype of ryanodine receptor (RyR) in pulmonary artery smooth muscle cell(PASMC) and the change of RyR expression from pulmonary hypertensive (PAH) rats. METHODS Rats pre treated with a single intraperitoneal injection of monocrotaline (MCT, 60 mg?kg -1 ) were used to produce PAH animal model and killed 21 d later. The subtype expression of RyR and the change of their mRNA were measured by RT PCR; protein expression of RyR was measured by Western blot in PASMC. RESULTS The PASMC of rats only expressed type ⅡRyR (RyR2). RT PCR showed the RyR2 mRNA concentration of PAH group was higher than that of control; Western blot demonstrated that the RyR2 protein level in PAH group was increased to (170 23?45 34)%. CONCLUSION PASMC only expressed RyR2 subtype and the increment of RyR2 expression may contribute to the pathological mechanism of PAH formation.

BackgroundCataract is a leading blinding eye disease,and the prevalence of cataract varies in different regions.ObjectiveThe present study was to investigate the incidence of cataract,surgical coverage rate of cataract and postoperative visual acuity,and to propose a strategy for blindness prevention in Chifeng Keshiketengqi.Methods This is a cross-sectional survey of research.A random cluster sampling method was performed in 12 populated areas in Keshiketengqi.Inhabitants over 50 years in the region were included in this survey.This study was approved by the Ethic Committee of Inner Mongolia People' s Hospital.Informed consents were obtained orally from all the subjects.Disease history,visual acuity,intraocular pressure and regular ophthamological examinations were performed.The inclusion criteria of a pilot study and detailed protocol were employed to calculate the incidence rate of cataract.The questionnaire survey was simultaneously adopted to analyze the cataract-related factors.The surgical coverage rate of cataract in this area was calculated.ResultsIn a total 4234 inhabitants,3826 subjects participated in the survey with a response rate of 90.36％.Cataract was found in 1200 participants with an incidence rate of 31.39％.Age,the female gender and illiteracy were identified as risk factors for cataract (x2 =101.005,P =0.000 ;x2 =58.853,P =0.000 ;x2 =12.037,P =0.007 ).The prevalence rates of cataract were 36.98％ and 33.56％ for illiterates and women,respectively.The incidence rate in the Mongol population was significantly higher than that of the Han population ( 34.83％ vs.29.76％ ) (x2 =9.734,P =0.001 ).The cataract surgery rate increased yearly since 1998.When the vision acuity of the fellow eye was ＜0.1,the surgery coverage rate was 20.60％,but the rates were lower in female,illiterates and the Mongol population (x2 =1.993,P =0.038 ;x2 =16.463,P =0.044 ;x2 =8.523,P =0.029).When a pinhole visual acuity of ＜0.05 was determined as the criteria of blindness,the surgical coverage rate was 28.36％.The cataract surgical coverage rates for Han and Mongolian were 30.67％ and 24.53％,respectively,with a significant difference between them (x2 =12.951,P=0.000).The social burden rate was 3.34％ in this area,with a majority of females,illiterates and the Mongol population ( P＜0.05 ).ConclusionsIn agricultural and pastoral areas of Chifeng Keshiketengqi,the ≥50 years old population has a high rate of cataract blindness and low surgery coverage rate.Surgery is still the preferred way for cataract treatment.

Background Trachoma is a common infectious eye disease,and its incidence is associated with region,economy and sanitary condition.To survey the prevalence status of an area is very important for the prevention and treatment of trachoma.Objective Aim of this study was to survey the prevalence of trachoma in primary and secondary school students of Chifeng Keshiketengqi,and to investigate the relationship between the prevalence of trachoma with age,gender,ethnicity and living environment.Methods This was a cross-sectional study.According to cluster random sampling method,2067 students were drawn from 10 primary and secondary schools,including 1061male and 1006 female.The age of students ranged from 6 to 17 years old,with the average age (12.53 ± 2.31)years.In the taken samples,Han students were 1768,and Mongolian students were 299;the agricultural and pastoral students were 1209,and the urban students were 858.The general life factors associated with trachoma were surveyed by questionnaire.Trachoma was diagnosed and graded based to 1987 WHO Simplified Trachoma Grading Standards.Eye examinations included visual inspection,eyelids,conjunctiva and cornea neovascularization under the slit lamp microscope,and the clinical data were recorded and collected.The results were statistically analyzed by SPSS13.0 software.Results According to the sampling proportion of 10.05％,2153 students were included and 2067 students participated in this study with the response rate 96％.Trachoma was diagnosed in 972 students with a morbidity 47.0％.The prevalence rate of trachoma was increased with the ageing,and a statistically significant difference was seen among the 6-8 years group,9-11 years group,12-14 years group and 15-17 years group (x2 =11.043,P =0.011),and the prevalence of trachomatous infiltration was significantly higher than that of trachomatous folliele (x2=11.493,P＜0.05).The prevalence rate of trachoma in Han and Mongolian students was 45.8％ and 54.5％,showing a significant difference between them (x2 =6.228,P =0.013).In addition,statistically significant differences also were found in the prevalence rate of trachoma between the pastoral areas students and urban students (56.1％ vs.39.7％,x2=30.226,P =0.000),but no significant difference was seen between male and female (47.0％ vs.46.9％,x2 =0.000,P =0.995).Conclusions The trachoma prevalence rate is relatively higher in the primary and secondary students in Chifeng Keshiketeng.These results offer a basis for the prevention and treatment of trachoma.
