Objective To study the clinical efficacy of axillary incision and thoracoscopic surgery for spontaneous pneumothorax.Methods 106 cases of spontaneous pneumothorax in our hospital were given axillary incision surgery(axillary incision group) and thoracoscopic surgery(thoracoscopy group).The intraoperative blood loss,operative time,chest tube drainage time,postoperative hospital stay and surgery costs were compared between the two groups,and the occurrence of complications were observed.Results The armpit small incision group,intraoperative blood loss was (44.5 ± 5.2) ml,the thoracoscopic amount of blood loss was (38.3 ± 6.5) ml (t =6.378,P ＜ 0.01) ;armpit operation time of the small incision group was (68.0 ± 5.3) min,thoracoscopic operative time was (60.8 ±6.0)min; armpit chest tube drainage time of small incision group was (2.8 ± 0.8)d,thoracoscopic group of chest tube drainage time was (2.0 ± 0.5) d; axillary small incision group,length of stay was (4.8 ± 0.7) d,the thoracoscopic group hospitalization time was (4.0 ± 0.6) d,(t =3.552,4.215,3.076,all P ＜ 0.05) ; axillary incision surgery costs was (1 550 ± 348) Yuan,the thoracoscopic group cost of surgery was (4 290 ± 573) Yuan (t =-24.823,P ＜ 0.05).Two groups of patients with no surgical complications,chest X-ray review of lung reexpansion good thoracoscopic group one cases of recurrence of pneumothorax,axillary incision group without recurrence (P ＞ 0.05).Conclusion Axillary small incision and thoracoscopic surgery for spontaneous pneumothorax have the similar efficacy,thoracoscopic surgery is less trauma,faster recovery,shorter hospital stay,but the high cost of surgery,if patients physical condition is acceptable,which can be used axillary incision surgery.

Objective To investigate clinical characteristics of smear- or culture-positive pulmonary tuberculosis (TB) in patients hospitalized at a general hospital to improve its diagnosis. Methods Clinical data of smear- or culture-positive pulmonary TB diagnosed in 50 patients hospitalized at Peking Union Medical College Hospital, Beijing during 2006 to 2009 were analyzed retrospectively. Results Seventeen (34%) of 50 cases of smear- or culture-positive pulmonary TB aged more than 60 years, with 30 males (32%), 16 retirees and nine farmers (18%). Their main symptoms included fever (80%), cough (94%) and sputum expectoration (92%), with elevated erythrocyte sedimentation rate (ESR) in 38 of 45 patients (84%). Chest X-ray examinations showed that lesions located mostly in the upper lobes or in both of the lungs diffusedly, with patchy infiltrations, nodular opacities and cavities. Acid-fast bacilli were demonstrated on sputum smear in 41 ( 82% ) and in specimens of six ( 12% ) cases obtained through bronchoscopy with brush or bronchoalveolar lavage fluid ( BALF), and M. Tuberculosis was cultured from sputum specimens in three (6%). Mean time interval between admission and diagnoses averaged 14 days.Conclusions Basic knowledge about prevention and control of pulmonary tuberculosis should be publicized comprehensively in general hospital keeping alert in its diagnosis with acid-fast staining for sputum smear as a routine test for patients with respiratory symptoms, and in some cases, bronchoscopy procedures ( brush or BALF) are reasonable options to improve its detection.

Objective To investigate the mechanical stability and clinical outcome of minimally invasive plate osteosynthesis of pubic ramus fractures.Methods Stability of minimally invasive plate osteosynthesis and traditional open fixation of pubic ramus fractures was compared in finite element analysis.A retrospective analysis was performed on fractures of pubic rami (126 sides) in 101 consecutive patients treated with minimally invasive plate osteosynthesis from 2005 to 2012.Operation time,intraoperative blood loss and follow-up of fracture healing were evaluated.Results In finite element analysis,traditional open fixation and minimally invasive plate osteosynthesis resulted in the maximum pelvic force of 7.35 MPa and 5.59 MPa,maximum fracture displacement of 4.31 mm and 4.38 mm and relative fracture gap displacement of 0.029 mm and 0.012 mm.Displacement of fracture gap after minimally invasive plate osteosynthesis and traditional open fixation was reduced 26％ and 59％ respectively.In the clinical study,the surgery acquired for pubic ramus fractures averaged 65 minutes with mean blood loss of 94 ml.Follow-up duration was 5-50 months (mean,24.3 months).Reduction of the fracture as assessed using Matta' s criteria was excellent in 118 sides (93.7％),good in eight sides (6.3％).Totally,the fracture was healed within postoperative 12 weeks in 117 sides and within postoperative 6 months in 9 sides.No iatrogenic nerve or vascular injury occurred.Conclusions Minimally invasive plate osteosynthesis is a safe and effective technique for fixation of pubic ramus fractures.Moreover,satisfactory results can be achieved together with less trauma and better cosmetic effect.

This study was aimed to choose the best fixing method of electrocardiogram (ECG) measurement in mice by comparison of ECG index in three different fixing ways. Changes of ST amplitude and heart rate in ECG were measured in the self-made mouse sets, tape bundling or breathing anesthesia state. The amplitudes of the ST seg-ment in C57BL6 mice and β1/β2-AR double knockout mice were elevated in tape bundling or breathing anesthesia state in comparison with that in the self-made mouse sets (all P < 0.01). The heart rate under the tape bundling state in C57BL6 mice was significantly faster than that in the self-made mouse sets (P< 0.05 or P< 0.01). And the heart rate under anesthesia in β1/β2-AR double knockout mice was significantly slower than that in tape bundling state or the self-made mouse sets (both P < 0.01). It was concluded that relative to the binding and anesthesia method, fixing mouse in the self-made mouse sets, which can more truly reflect the physiological or pathological states, is a relatively good fixing method of ECG measurement in experimental study.

Objective To investigate the relation between the characteristics of body fat distribution and the cardiovascular risk factors in some patients with type 2 diabetes mellitus (T2DM)in Xinjiang region.Methods The percentage of body fat (PBF)and visceral fat area(VA)were determined in 155 cases of T2DM by using the Inbody 720 body composition analyzer.At the same time triglycerides(TG),total cholesterol(TC),high density lipoprotein(HDL-C),low density lipoprotein(LDL-C),blood pressure(BP), glycosylated hemoglobin HbA1c,body weight(W),body height,waist circumference ratio(WC)and hip circumference(HC)were also determined.The body mass index(BMI)and the waist to hip ratio was calculated.Results In both men and women,BMI in the subjects with visceral fat obesity(VFO)was higher than that with subcutaneous fat obesity(SFO).In males,TG in VFO was signif-icantly higher than that in SFO.PBF,TC and LDL-C in the female T2DM patients were significantly higher than those in the male T2DM patients.VA and PBF in the minority male patients were significantly higher than those in the Han nationality male patients (P <0.05).After correcting the age,course of disease and BMI,WHR in the female patients was positively correlated with DBP and PBF was positively correlated with LDL-C.In the male patients,there were correlations between BMI with SBP,between VA with DBP,and between VA with PBF and HDL-C;in the female patients,there were correlations between BMI with SBP and be-tween WHR with DBP.Conclusion The body fat distribution in the patients with T2DM in Xinjiang region is dominated by VFO. The cardiovascular risk factors are not only associated with the increase of body fat content,but more closely associated with VFO, moreover the differences in genders and nationalities exist.

Objective To understand the dynamic conditions after reaching the stage goal of elimination of iodine deficiency disorders (IDD) in Wenzhou, and to provide a scientific basis for prevention and treatment of IDD. Methods Three counties that the annual consumption rate of qualified iodized salt < 80% in 2014 and had the prevalence of endemic cretinism in history, Cangnan, Taishun and Yongjia, were selected as high risk monitoring areas. Three townships were selected in each area, and two primary schools were selected from each township, and 40 children urine samples were collected in each school (half male and half female) and the age of children were 8-10 years old. And near the location of these primary schools, we randomly selected 10 pregnant women in each village, and estimated the urinary iodine level and salt iodine concentration, respectively. The examination of thyroid by B ultrasound was performed in children by provincial professionals. Urinary iodine was determined using the arsenic cerium catalytic spectrophotometric method (GB/T 13025.7-2012). Salt iodine was determined by direct titration. Results Endemic cretinism case was not found in this survey, total goiter rate of 8-10 years old children was 2.04%(16/783). The median of urinary iodine was 116.1 and 108.2 μg/L, respectively, in 8 - 10 years old children and pregnant women. Iodized salt coverage rate was 90.48%(171/189), the intaking rate of qualified iodized salt was 84.66% (160/189). The concentration of pregnant women urinary iodine and salt iodine was positively correlated (r=0.54, P< 0.05). Conclusions Children's iodine nutrition is in the appropriate level, but pregnant women are in iodine definciency in Wenzhou City.

Objective To investigate the G protein-coupled receptor kinase 2 (GRK 2) level in peripheral blood lymphocytes with cardiac func-tion in elderly patients with acute myocardial infarction. Methods This study enrolled 40 patients with acute ST-segment elevation myo-cardial infarction (STEMI) and 40 patients with unstable angina. All patients were 65 years or older. Cardiac function was evaluated by echocardiography, and the GRK 2 level in peripheral blood lymphocytes was measured. Patients with STEMI were followed up for 2 years. Results The GRK 2 level in peripheral blood lymphocytes was significantly higher in patients with STEMI than in patients with unstable angina, and was negatively correlated with left ventricular ejection fraction, cardiac output, stroke volume, and left ventricular fractional shortening. The GRK 2 level was significantly elevated in some patients with acute STEMI and poor cardiac function. Conclusions In-creased GRK 2 level in patients with acute STEMI may contribute to poor myocardial systolic function and myocardial remodeling. Meas-urement of the GRK 2 level in peripheral blood lymphocytes may assist in the evaluation of cardiac function and myocardial remodeling in elderly patients with acute STEMI.
