Objective To observe the effects of pulsed electromagnetic field (PEMFs) or/and exercise on the area bone mineral density (aBMD) and volume bone mineral density (vBMD) of rats with osteoporosis induced by tretinoin gastric perfusion.Methods 100 female SD rats were randomly divided into 5 groups with 20 rats in each group： PEMFs group, exercise group, PEMFs plus exercise group, osteoporosis group and healthy control group. Except for the healthy control group, the osteoporosis models of other 4 groups were built by tretinoin gastric perfusion. After the building of models, each group was intervened with different treatment. In the 4th, 6th and 8th week after treatment, relevant Results of aBMD and vBMD were tested.Results Compared with the osteoporosis group, the BMD of the rats of PEMFs group, exercise group, PEMFs plus exercise group significantly increased significantly ( P＜0.05) in the 6th week, 4th week and 4th week after treatment respectively. In the 6th and 8th week, there was no significant differences among the PEMFs plus exercise group, the exercise group and the PEMFs group ( P>0.05).Conclusion PEMFs can increase the BMD of the rats with osteoporosis as well as exercise. PEMFs takes effect slower than exercise.

Objective To investigate the risk factors for hip fracture in elderly people in Ningbo,in order to provide the basis for prevention and treatment of hip fracture.Methods A case-control study were conducted in study on 450 cases of hip fracture patients aged over 60 years in Ningbo and 450 subjects of control as 1 ∶ 1 matched case control study.A univariate analysis of hip fracture was performed by x2 test.Risk factors for hip fracture were analyzed by logistic regression.Results Poor self-care ability (OR=5.05),light manual labor occupation (OR=4.10),history of cerebrovascular events (OR=2.59),smoking (OR=2.14) were the risk factors for hip fracture in elderly men,while poor self-care ability (OR=11.36),light manual labor occupation (OR=2.41),osteoporosis (OR=3.19),early menopause (OR=6.89),low body mass index (OR=5.05) were the risk factors for hip fracture in elderly women.The protective factors for hip fracture was milk uptake (OR=0.29) Conclusions Early interventions for hip fracture risk factors,and prevention and treatment of osteoporosis can help reduce the occurrence of hip fracture.

Objective To investigate the efficacy of small-axillary-incision esophagectomy combined with mechanical esophagogastric anastomosis for esophageal carcinoma.Methods From April 2005 to April 2007,56 patients with esophageal cancer underwent small-axillary-incision esophagectomy combined with mechanical esophagogastric anastomosis in our hospital.After thoracotomy was performed via a small axillary incision,the stomach and esophagus were separated.Circular stapler was used for esophagogastric anastomosis after esophagectomy.The anastomotic segment was then enveloped and placed at the esophageal bed.Results The average length of the axillary incision was(13.2?1.6)cm(10-15 cm).No anastomotic leak and hemorrhage,injury to the laryngeal nerve,or chylothorax occurred in this series.53 of the patients were followed up for 4-16 months(mean,7.8 months),during which 1(1.9%)patient developed slight anastomotic stenosis,and 4(7.5%)had gastroesophageal reflux.Conclusions Small axillary incision causes less trauma to the patients leading to a quick recovery.By using mechanical cervical anastomosis,man-mad injuries to the anastomotic segment are avoided,resulting in a low rate of postoperative complications.

Objective To investigate the correlation between cerebral artery stenosis (MCAS) and mild cognitive impairment (MCI).Methods Continuous selected 636 cases of 50-80 years old inpatients or outpatients who examined by transcranial color Doppler ultrasound (TCD) in April 2012 to April 2013 in our hospital.Keep the mini-mental state examination (MMSE) and clinical dementia rating (CDR) as the evaluation of cognitive function.Results Detected 124 cases of MCAS patients (MCAS group) and 512 cases of non-MCAS patients (non-MCAS group).Forty-four cases MCI were detected in MCAS group with the prevalence rate was 35.5％(44/124),and 114 cases of patients with MCI were detected in non-MCAS group with the prevalence rate was 22.3％ (114/512),the difference was statistically significant (P ＜ 0.05).Single factor analysis showed that there were no significant difference between two groups in waist circumference,hypertension,coronary heart disease,hyperlipidemia,smoking,diastolic blood pressure and total cholesterol,uric acid,fasting glucose,C-reactive protein (P ＞ 0.05); There were significantly different between two groups in age,gender,education level,MCAS,history of diabetes,systolic blood pressure and triglyceride,low density lipoprotein-cholesterol,high-density lipoprotein-cholesterol(P ＜ 0.05).Multiple factors analysis showed that the MCAS (OR =1.899,95％ CI 1.224-2.946),history of diabetes (OR =1.764,95％ CI 1.191-2.612),systolic blood pressure(OR =1.012,95％ CI 1.003-1.022),gender (OR =0.558,95％ CI 0.380-0.821),and age (OR =1.029,95％ CI 1.010-1.049) was the independent risk factor for MCI.Conclusion The MCAS related with MCI occurrence and development.

Objective To discuss perioperative features, operative approach and surgical effects of spinal tuberculosis in older patients. Methods Retrospective analysis was conducted to analyze the clinical data of 45 patients with spinal tuberculosis ranging in age from 61 to 78 years (average, 67 years). The lesion was located in thoracic vertebrae in 9 patients, thoracolumbar vertebrae in 14, lumbar in 16, and lumbosacral in 6. Preoperative Frankel grades were B in 7 cases, C in 21, D in 11 and E in 6. Among them, 21 had cardio-cerebrovascular disease, 10 had diabetes mellitus. With preoperative medicine and chemotherapy for 2-3 weeks, all patients were treated surgically. The surgical procedures included: 1) Posterior focus debridement, bone grafting and one-stage posterior transpedicular screw system fixation in thoracic vertebrae (T2-T7). 2) Anterior debridement, bone grafting and one-stage posterior transpedicular instrumental fixation in lumbosacral vertebrae (L5-S1). 3) Anterior focus elimination, bone grafting and one-stage anterior plate fixation in the other vertebrae. Results Forty-five patients were followed up for 24 to 40 months, with the average of 28.5 months. No severe complication occurred during and after operation. Forty-four cases had recovered and 1 recurred. Spinal fusion occurred 12-18 months after operation. Frankel neurological grades improved significantly. Conclusion With the effective management of comorbidities in perioperative period,the elderly could tolerate surgical treatment. The appropriate approaches, thorough debridement and reasonable bone grafting with internal fixation are key to therapeutic success.

Objective To investigate the clinical features and the management of primary pigmented nodular adrenocortical disease PPNAD) and to evaluate its relationship with Carney complex. Methods One case of PPNAD reported. The patient was a 52 years oldmale. He was hospitalized because of hypertension for one year. The patient had a Cushing's face with elevated plasma and urine cortisone levels which could not be suppressed by both low dose and high dose dexamethasone tests. Ultrasonography howed normal bilateral adrenal glands. CT scan found a 1.6 cm × 2.0 cm mass in the left adrenal gland and normal on tralateral adrenal gland. Results The patient had accepted left laparoscopic adrenalectomy. The pathological examination onfirmed the diagnosis of PPNAD. Micro scopic study showed that there were black-gray spots in the center of the specimen. Hyperplasia was found in all the three adrenal zones. Lipofuscin was observed in the cytoplasm of reticular zone cells. The patient's blood pressure had returned to normal level after the surgery. Conclusions PPNAD is a rare type of ypercortisolism. As there is no specific feature in clinical manifestation and radiological examination of this disease, it is very easy to make a misdiagnosis in clinical practice. PPNAD itself can be the comorbidity of Carney complex, careful differentiation is needed.

Objective To investigate the effects of exercise therapy and health education on the hospitalization and exercise endurance of patients with moderate or severe chronic obstructive pulmonary disease (COPD).Methods A total of 86 patients with moderate or severe but stable COPD were divided randomly into an observation group (n=46) and a control group (n=40).The patients in both groups accepted general respiratory medical therapy.The patients in the observation group also accepted additional pulmonary rehabilitation therapy which consisted of exercise and health education while the patients in the control group only accepted health education and rehabilitation training guidance by telephone instead of standardized pulmonary rehabilitation therapy.The average recurrence of hospitalization,length of stay,and total bed time of all of the patients was tracked for a year before and after enrolment.Their 6 minute walking distance (6MWD) and quality of life (QOL) as reflected by using a scale recommended by the Chinese Society of Respiratory Disease before and after entering the study were evaluated.Results There was no significant difference between the groups in the year before entering the study in terms of their average frequency of hospitalization,length of stay or total bed time.In the year after enrollment average frequency of recurrence requiring hospitalization,length of stay and total bed time in the observation group all decreased significantly compared with the previous year,and all were significantly lower than in the control group.There were no significant differences between the groups in average 6MWD or average QOL score at entry,but in the subsequent year both groups' results improved significantly.Conclusion Long term pulmonary rehabilitation can not only enhance exercise endurance,it also improves QOL and relieves the economic burden of COPD patients on society.
