Objective To investigate the mid-term outcome of high tibia osteotomy (HTO) combined with tibial tuberosity limited rotation in the treatment of disorder of patellofemoral joint with knee varus.Methods HTO was performed in all 42 patients.The lower limb alignment,lateral femoral tibial angle,medial proximal tibial angle,Q angle and TF-TG were measured before and after operation.All the patients with disorder of patellofemoral joint were divided into three types based on preoperative patellar trajectory and TF-TG.According to different types we chose the limided rotation of distal tibia through adjustment of tibial tubercle location to improve patellar track.Type Ⅰ in 10 cases and type Ⅱ in 12 cases only accepted HTO,type Ⅲ in 20 cases accepted HTO and tibial tubercle rotation.The rotation angle was determined according to preoperative imaging results and foot forward angle.Before and after operation patellar tilt angle,patellofemoral angle and lateral patellar angle were measured.Results 42 patients were followed up for more than 5 years,an average of 72.20± 12.60 months (60-88 months).No nerve damage,infection and bone nonunion occurred.The patellar tilt angle was improved from 12.45°±3.76° to 6.98°± 1.78° 5 years after operation.The patellofemoral angle was improved from 12.51°±4.71° to-4.70°±2.57° 5 years after operation,and the lateral patellar angle was improved from 1.50°±4.90° to 7.80°±3.10°.Preoperative lateral femoral tibial angle was improved from 182.45°±2.20° to postoperative 174.60° ±3.50°,medial proximal tibial angle was improved from preoperative 78.75°± 3.50° to postoperative 93.25°±1.95°.The Lysholm score was improved from preoperative 53.10±5.60 to 92.70±5.50.The preoperative IKDC subjective score was improved from 47.50±6.40 to 91.30±6.90.The Kujala score was 62.40±8.70 before operation and 87.30±4.10 5 years after operation.Visual analogue score (VAS) was 7.50±2.45 before operation and 1.50±0.90 5 years after operation.The short and mid-term follow-up,knee patellar trajectory and lower limb alignment was good,postoperative symptoms was satisfactory and acceptable.Conclusion HTO combined with limited rotation of the tibial tubercle could improve patellar trajectory and lower limb alignment to relieve pain,and has satisfactory mid-term outcome in the disorder of patellofemoral joint with knee yarus patients.

Background:Studies have shown that promoter methylation of MGMT gene is closely related to many malignant tumor including gastric cancer.DNA methyltransferase 1 (DNMT1) is highly expressed in many malignant tumor tissues.However, studies on relationship between methylation of MGMT gene and DNMT1 expression in gastric cancer are rare.Aims:To investigate the relationship between methylation of MGMT gene, protein expression of DNMT1 and gastric cancer.Methods:Promoter methylation status of MGMT gene in 60 gastric adenocarcinoma tissues and corresponding paracancerous tissues were detected by methylation-specific PCR (MSP).RT-PCR and immunohistochemistry were used to measure mRNA and protein expressions of MGMT and DNMT1, respectively.Results:Methylation rate of MGMT gene promoter in gastric cancer was significantly higher than that in paracancerous tissue (45.0% vs.13.3%, P<0.001).The positivity rate of MGMT mRNA in gastric cancer was significantly lower than that in paracancerous tissue (41.7% vs.93.3%, P<0.001), while the positivity rate of DNMT1 mRNA expression in gastric cancer was significantly higher than that in paracancerous tissue (76.7% vs.18.3%, P<0.001).Methylation rate of MGMT promoter in MGMT mRNA-negative expressed gastric cancer tissue was significantly higher than that in MGMT mRNA-positive expressed gastric cancer tissue (57.1% vs.28.0%, P<0.05).It showed a negative correlation between MGMT protein expression and DNMT1 protein expression in gastric cancer tissue (r=-0.795, P<0.01).Conclusions:Promoter methylation of MGMT gene and high expression of DNMT1 may be associated with the development and progression of gastric cancer.

Objective: To investigate the management of NH~-_3 burned cases with inhalation injury. Methods:The clinic treatments of 15 NH~-_3 burned cases complicated with inhalation injury in his hospital between January 1998 and April 2004 were analyzed retrospectively.His management included reasonable fluid therapy,prompt and efficient usage of antibiotics ,tracheotomy after diagnosis,mechanical ventilation,bronchoalveolar lavage using fibrobrochoscope after the shock period and short-time usage of glucocorticoid. Results: Of the 15 cases,14 patients were cured and 1 patient was improved without any death.The cure rate was 93.3%. Conclusion: All of the managements should be performed as quickly as possible.Paying much attention to prevent the complications could improve the cure rate.Tracheotomy and bronchoalveolar lavage in the early stage are vital to patients.

Conclusion Well grasping principles of the air compressor of ventilators, and timely & correct analysis of malfunctions reasons play key roles in solving all kinds of malfunctions associated with the air compressor of ventilators.

Chronic overuse disease of the shoulder is very common in clinical practice.Its pathogenesis is complicated and its treatment is often a combination of medication,rehabilitation and surgery.In recent years,its diagnosis tends to be more definite,leading to more specific treatment.Extracorporeal shock wave therapy has been successfully used in the treatment of such orthopaedic diseases as plantar fasciitis and lateral epicondylitis,and has been tried by some scholars in the treatment of chronic overuse disease of the shoulder.Its therapeutic effect has also been demonstrated to some extent on calcific tendonitis,non-calcific tendonitis and adhesive capsulitis.This review outlines the progress in research of extracorporeal shock wave therapy for the treatment of chronic overuse disease of the shoulder.

Objective To study the effect of aspirin in the prevention of cardiovascular events for patients with hypertension.Methods 105 patients with hypertensive disease were randomly divided into group A,B,C, 35 cases in each group,and group A was dealed with nifedipine tablets treatment,group B were treated with nifedipine tablets and aspirin,group C was given nifedipine tablets and dipyridamole.The antihypertensive effects of the three groups were observed,three years through regular follow -up for all patients,the effects of prevention of cardiovascular events in patients with essential hypertension were observed.Results The occurrence probability of myocardial infarction,cerebral infarction and cerebral hemorrhage in the group B were 2.85%,2.85%,0.00%,respectively, which were statistically significant less than those in the group A and C group(F =19.4,P <0.05).Conclusion The preventive effect of aspirin is better for cardiovascular events in hypertensive patients,which is worthy to be popu-larized and used in clinical studies,aspirin for this kind of disease is a kind of ideal.

OBJECTIVE: To summarize the recent progress and clinical application of percutaneous coronary intervention and to seek the direction of new developments.METHODS: A computerized online database of Pubmed was searched to identify articles published from May 2000 to February 2009 with the key words of "drug eluting stents, peroutaneous coronary intervention, and coronary disease". There were 154 articles were retrieved by computer, by reading tities and Abstract s, 27% literatures were remained after excluding 74 irrespective papers and 53 repetitive studies.RESULTS: An ideal drug-eluting stent (DES) was comprised of a platform, a drug carrier vehicle and a pharmaceutical compound in harmony with each other. With the ongoing development of DES materials and drugs, more effective DES was introduced in the practice. Recently, clinical data on DES encourage the interventional cardiologist to use DES in more challenging coronary lesions, such as chronic total occlusions, complex lesions and multi-vessel lesions. However, the safety and efficacy of DES need further attention. Therefore, novel strategies including bioabsorbable stents, and pro-healing agents coated stents were promising.CONCLUSION: The development of percutaneous coronary intervention is a breakthrough in intervention cardiology that brings great benefit to patients with coronary disease, especially for restenosis and revascularization. Nevertheless, more endeavour will be necessary to create PCI with high efficacy as well as low risk, and safety and effectiveness of PCI in patients with ST-segment evaluation myocardial infraction and stent fracture prevention need further study.
