Objective To explore the relationship between visceral pleura closure of primary spontaneous pneumotho?rax (PSP) using different diameters of drainage tube and the time of implementing closed chest-drain. Methods According to the diameters of tubes for chest drain they used, 214 patients with PSP were divided into standard tube group (136 cases) and fine catheter group (78 cases). Patients in standard tube group who were inserted chest drain for≤1 d,≤3 d,≤6 d,>6 d included 48, 43, 29 and 16 cases respectively while their counterpart in fine catheter group include 24, 23, 17, 14 cases re?spectively. Closed time of crevasse were noted and incidence of preoperative closed pneumothorax converting into open pneu?mothorax, subcutaneous emphysema and prolonged pain after operation were all recorded. Results There is no statistical difference in closing time of crevasse nor in the distribution of various drainage times (proportions of≤6 d and>6 d are low?er than proportions of≤1 d and≤3 d) between standard tube group [(4.76 ±1.65) d] and fine catheter group [(4.54±1.67) d] (t=0.963). However, in both standard tube group and fine catheter group, closing time of crevasse is shorter if drainage time≤6 d or>6 d than if it≤1 d and≤3 d. Closing time of crevasse show negative correlation with period of chest drain in?sertion in both standard tube group and fine catheter group (P<0.05). The rate of converting from close pneumothorax into open pneumothorax were 51.96%(53/102) and 36.21%(21/58) respectively in standard pipe group and fine catheter group. Furthermore, the incidence of subcutaneous emphysema and prolonged pain were all higher than those in standard tube group than those in the fine catheter group (P<0.05). Conclusion Using closed chest drain to treat patients with PSP, di?ameter of the drain tube did not affect closing time of crevasse. But longer insertion period of chest drain can reduce closing time of crevasse.

Objective To explore the effects of action observation therapy on upper-extremity motor function and ability in the activities of daily living after cerebral infarction.Methods Forty-one cerebral infarction survivors were randomly assigned to an observation group (n =21) or a control group (n =20).Both groups were given the conventional rehabilitation treatment,while the observation group additionally received action observation therapy 20 mins per day,6 times per week for 8 weeks.Before and after the 8 weeks of treatment,both groups were assessed using the Fugl-Meyer assessment (FMA),Wolf's motor function test (WMFT) and the modified Barthel index (MBI).Results Before the intervention there was no significant difference between the groups in any of the measurements.After the 8 weeks of treatment,all of the results in the treatment group were significantly better,on average,than those of the control group.Conclusions Action observation therapy can improve upper-extremity motor function and ability in the activities of daily living after stroke.

Background Papillary thyroid cancer is the result of a variety of pathogenic factors. The prevalence of papillary thyroid cancer varies greatly in different regions, and the disease is more harmful to women. Objective This study aims to explore the relationship between reproductive factors and papillary thyroid cancer, and to provide basic data for prevention and control of the disease. Methods A 1∶1 age (±3 years) matched case-control study was conducted in 331 pairs of newly confirmed papillary thyroid cancer cases and controls from two hospitals in Shanghai from November 2012 to December 2013. Comparisons were made in the history of menstruation, pregnancy, gynecological and breast diseases, and other variables between the two groups. Results The results of univariate analysis indicated that the proportions of education below bachelor degree, married, and mainly manual workers in the case group were significantly higher than those in the control group (P<0.05); the proportion of those with a family history of thyroid diseases in the case group was significantly higher than that in the control group (P<0.05); the proportions of the cases with irregular menstruation (77.34%), a history of using oral contraceptive or hormone drugs (24.77%), a history of benign gynecological diseases (31.72%), and a history of gynecological surgery (9.67%) were significantly higher than the proportions in the control group (P<0.05). After adjusting potential confounding factors such as history of CT examination, age, kinds of family salt, total iodine intake every day, education level, occupation, marital status, body mass index, and family history of thyroid diseases, the results of multiple logistic regression analysis showed that irregular menstruation (OR=1.767, 95%CI: 1.122-2.782; P=0.014), surgical menopause (OR=12.787, 95%CI: 3.202-51.057; P<0.001), pregnancy >1 time (OR =2.490, 95%CI: 1.196-5.184; P=0.015), and the history of using oral contraceptive or hormone drugs (OR=2.389, 95%CI: 1.338-4.268; P=0.003) were the risk factors of papillary thyroid cancer. Conclusion Irregular menstruation, surgical menopause, history of pregnancy, and history of using oral contraceptive or hormone drugs might be the risk factors of papillary thyroid cancer. To reduce the incidence of papillary thyroid cancer, strengthened health education and rational use of contraceptives are recommended.
