Objective To evaluate the clinical results using modified Richards nail treating femoral intertrochanteric comminuted fractures.Methods From March 2002 to March 2005,69 patients suffered from femoral intertrochanteric comminuted fractures belong to Evan Ⅲ type or Ⅳ type were randomly divided into experimental group and control group.The experimental group was treated with modified Richards nail,including 34 patients,18 males and 16 females.The patients were from 61 to 78 years old,and the mean age was 67.5 years old.In this group,21 patients were involved in left femoral intertrochanteric comminuted fractures,13 patients were involved in right.The pattern of the fractures included EvanⅢ type in 24 cases and Ⅳ type in 10 cases.The control group including 35 patients was treated with DHS,and there were 19 males and 16 females with an average age of 65.9 years(ranged 61 to 80 years).In this group,19 patients were involved in left femoral intertrochanteric comminuted fractures,16 patients were involved in right.The pattern of the fractures included EvanⅢ type in 25 cases and Ⅳ type in 10 cases.Results The experimental group were followed-up 9-23 months with a mean of 11.60?3.78 months.The control group were followed-up 9-24 months with a mean of 11.40?4.12 months.In experimental group,the average fracture healing time was 3.65?0.97 months.While in the control group,the average fracture healing time was 4.32?1.38 months.In experimental group,the leg length measured at the 9th month post-operatively was averagely(0.82?0.36)cm shorter in the diseased side than in the healthy side,while in control group the leg length was averagely(1.08?0.51)cm shorter.There was significant difference between two groups.Compared to the control group,the curative effect was better in the experimental group.Conclusion Treating femoral intertrochanteric comminuted fractures with the modified Richards nail shows a good result,which can effectively diminish the non-union or mal-union of the fractures.

Hospital business process optimization and reengineering is an effective method and channel for hospitals to enhance medical and management quality, realize cost minimization, improve efficiency, and increase benefits. The paper gives an account of the theories, methods, steps, relevant techniques, and tools of hospital business process optimization and reengineering, discusses the systematic framework for hospital business process improvement and key success factors and obstacles for hospital business process reengineering, analyzes the relationship of business process reengineering with hospital organizational structures and hospital information systems, and puts forward assessment criteria for hospital business process optimization and reengineering.

Objective To identify a unique protein as a novel genetic marker for rapid molecular typing of Mycobacteriutn tuberculosis Beijing genotype strains by comparing the proteome of Beijing genotype strains with non-Beijing strains.Methods Fifty-six clinical isolates of Mycobacterium tuber- culosis were analyzed by spoligotyping to determine genotypes.The two-dimensional electrophoresis (2 DE)was used to compare the global protein patterns between Beijing genotype strains and non Bei jing strains.Differential expressed proteins were measured by matrix assisted laser desorption ioniza tion lime of flight mass spectrometry(MALDI-TOF-MS).The data obtained from peptide mass fingerprinting were compared in protein database.The genes encoding differential expressed proteins and their upstream were sequenced.Results Forty nine of the 56 isolates were Beijing genotype strains and 7 isolates were non-Beijing strains.A unique protein Rv0927c was identified,which is absent in Beijing genotype strains compared with 7 non Beijing strains and H37Rv.There were two characteristic mutations in Beijing genotype strains,a deletion of AGC at nucleotide position 421 of Rv0927c and a 127 G→A muta- tion in the upstream of Rv0927c.but not in non Beijing strains and H37Rv.Conclusion Characteris tic mutations of Rv0927c in Beijing genotype strains can be used as a novel genetic marker for rapid molecular typing of Mycobacteriuln tuberculosis Beijing genotype strains and non Beijing strains.

Objective: To investigate the relationship between senile degenerative valvular heart disease (SDVHD) and heart failure. Methods:86 cases of SDVHD consisted of 67 males and 19 females, with the mean age of 60 -93(78?9)yr . 86 cases of controls with comparable gender, age and baseline conditions were include in the control group. Morbidity rate of heart failure were compared between the two groups during 12 years follow-up. Heart function was determined by color Doppler ultrasonography. Results:Prevalence of left heart failure and whole heart failure in SDVHD group were 75. 5% and 22. 0% , respectively, significantly higher than the control group ( 16. 2% and 7. 0% , respectively). Ejection fraction ( Ef) in SDVHD group was significantly lower than the control group [ (43?7 ) % vs (71?6)%,P

Objective To investigate the effect of preconditioning with sodium butyrate on myocardial I/R injury. Methods Anesthetized rats were treated with sodium butyrate (100 or 300 mg/kg, i.p.) 30 mins before ischemia, and then subjected to ischemia for 30 min followed by reperfusion for 4 h. LDH, CK, TNF-α, IL-6, HMGB1, infarct size, MDA and SOD activity were measured. The infracted size was tested by TTC assay; The expression of HMGB1 was observed by western blot. Results After 4 h reperfusion, pretreatment of sodium butyrate (300 mg/kg) could significantly reduce the infarct size and the levels of LDH and CK (P<0.05)comparing to the control group; inhibit the increase of the MDA level and the decrease of the SOD level(P<0.05), also inhibit the expression of TNF-α, IL-6 and HMGB1 (all P < 0.05) induced by I/R. Conclusion Preconditioning of sodium butyrate can attenuate myocardial I/R injury by inhibiting inflammation response.

Objective To explore the application of gastric(enteric)-pharyngeal anastomosis for cervical esophageal carcinoma. Methods The clinical data of 12 cases with surgical management of cervical esophageal carcinoma were retrospectively analyzed. Results The resectability of cervical esophageal carcinoma was 100%,no case complicated with pharyngeal fistula.Swallowing function of all cases was in a good state.The overall follow-up was 1 to 7 years,among them 9 surviving,3 dead.The surviving 5 cases are over 3 years,the ongest beyond 7 years. Conclusions Gastric(enteric)-pharyngeal anastomosis is a good primarily rehabilitating method of the cervical esophageal defect after surgical treatment of cervical esophageal carcinoma.

Objective To evaluate the clinical effectiveness in screening asymptomatic diabetic peripheral neuropathy(ADPN) by the Michigan neuropathy screening instrument (MNSI) and the Toronto clinical scoring system(TCSS).Methods MNSI,TCSS and neural electrophysiological test (NET) were conducted in 232 neurologically asymptomatic type 2 diabetes patients.By using the results of NET as the golden criteria for diagnosis of ADPN,we evaluated the effectiveness of the two different scoring system by the receiver operator characteristic curve.The sensitivity,specificity,positive and negative predictive values,accuracy,Youden indexes and kappa values on different diagnostic cut-off points of MNSI and TCSS were analyzed.The correlation between the two different scoring system and the risk factors of diabetic peripheral neuropathy (DPN) were also analyzed.Results The area under the ROC curve of MNSI and TCSS were 0.792,0.704,respectively.The sensitivity,specificity,accuracy,Youden indexes and kappa values of MNSI over 2 and TCSS over 2 were 66.2％ vs 73.3％,90.4％ vs 63.7％,78.3％ vs 68.5％,0.566 vs 0.370,and 0.588 vs 0.345,respectively.MNSI was better than TCSS in the effectiveness of diagnosing ADPN and consistence with the result of NET.Moreover,MNSI was associated with the most related risk factors of DPN including age,glycosylated hemoglobin (HbA1c),HbA1c × disease duration,islet function and HDL-C.Conclusions MNSI could be used as a relatively simple and reliable method for clinical and epidemiological screening and assessment of ADPN.
