Objective To explore the influence of Toxoplasma tachyzoites infection on motility of human spermatozoa in vitro, and explain its possible mechanism. Methods Semen samples obtained from 10 healthy volunteers by masturbation were prepared by the swim-up technique. The samples were then inoculated at 37 ℃ with different concentrations of live Toxoplasma tachyzoites varying among 1?103/ml (Group A), 1?104/ml (Group B), 1?105/ml (Group C), 1?106/ml (Group D), 1?107/ml (Group E) and Group F containing Ham’s F-10 only as the negative control. Motion parameters were analysed by Computer-aided sperm analyzer(CASA) in 0 hour, 1 hour, 2 hours, 4 hours respectively. Modalities of spermatozoa and possible adherence and/or agglutination were observed under the light microscope. Results Distinct adhesion of spermatozoa to Toxoplasma tachyzoites and agglutination were noticed. In all the motion parameters, progressive motility was affected most and dependent upon the incubation time and tachyzoites concentration. Progressive motility showed a significant difference between Group E and the control (P

Objective To explore the efficacy of two treatment methods for thoracic tuberculosis.Methods According to the different surgical methods,61 patients with thoracic tuberculosis were randomly divided into A group (31 cases) and B group (30 cases).A group was treated with simple thoracic tuberculosis soft tissue lesions removed,and B group was treated with focus removal + rib resection + muscle flap packing.The operation time,pain time,extubation time,hospital stay,wound fluid,cure rate and recurrence rate were compared between the two groups.Results The operation time,pain time,hospital stay time of A group were shorter than those of B group [(35.0 ± 11.0)minvs.(50.0 ±9.5)min,(1.8±1.3)d vs.(4.2 ±2.4)d,(12.5 ±3.4)d vs.(18.8 ±5.7)d],the differences were statistically significant (t =6.257,4.275,5.334,all P ＜ 0.05).There were no statistically significant differences in the extubation time,wound effusion,cure rate and recurrence rate between the two groups [(5.8 ± 3.1) d vs.(5.5 ± 2.8) d,2 cases vs.1 case,100.0％ vs.100.0％,6.4％ vs.3.3％,t =8.691,x2 =9.867,13.674,15.871,all P ＞ 0.05].Conclusion Analysis of the specific situation should be individualized on the chest wall tuberculosis,in the case of rib destruction,the focus should be removed + rib resection + muscle flap packing,if there is no rib destruction,simple chest wall tuberculosis soft tissue lesions removal is more safe,because it is less traumatic for patients.

In China,lack of suitable varieties,appropriate dosage forms and specifications,weak foundations on clinical trials,irregular prescribing behavior and irrational drug use and other issues on pediatric drugs are still outstanding. To improve pediatric drug accessi?bility,it may need all aspects work together,that is,cooperation of the national macro-policy support,participation of enterprises and medical institutions,to establish realistic goals and programs to address pediatric drug problem. This paper studies the foreign pediat?ric regulation measures and policies and by comparing foreign policies to China′s current situation,we can find out the problems and defects,give appropriate advice,in order to provide advice and reference to promote the development of pediatric drug.

Objective To provide rationales for preventing and treating dyslipidemia by understanding the current status of lipids and related metabolic factors.Methods A total of 2 590 permanent residents aged ≥ 18 years were selected by random cluster sampling from three urbanized communities of Sijiqing Street.And the rate of abnormal lipid metabolism was calculated for different ages and genders.Spearman's correlation analyses were conducted for the levels of total cholesterol (TC),total triglyceride (TG),low density lipoprotein-cholesterol (LDL-C),high density lipoprotein-cholesterol (HDL-C),body mass index (BMI),waist circumference (WC),systolic blood pressure (SBP),diastolic blood pressure (DBP),fasting plasma glucose (FPG),glycated hemoglobin (HbA 1 c) and uric acid (UA) levels.Both x2 test and logisic regression were employed to examine the correlations between dyslipidemia and overweight/obesity,hypertension,hyperglycemia and hyperuricemia.Results ① The total rate of abnormal lipid metabolism was 60.0％ (1 554/2 590) with a standardized rate of 57.2％.High TC rate was 42.9％ (1 111/2 590) with a standardized rate of 40.5％.And the edge incremental rate was 31.7％ (822/ 2 590),the standardized rate 30.5％,the incremental rate 11.2％ (289/2 590) and the standardized rate 10.0％.High TG rate was 33.0％ (855/2 590) with a standardized rate of 30.7％.And the edge incremental rate was 15.3％ (397/2 590),the standardized rate 14.3％,the incremental rate 17.7％ (458/2 590) and the standardized rate 16.4％.High LDL-C rate was 30.4％ (787/2 590) with a standardized rate of 28.4％.And the edge incremental rate was 22.9％ (594/2 590),the standardized rate 21.7％,the incremental rate 7.5％ (193/2 590) and the standardized rate 6.7％.Low HDL-C rate was 12.6％ (327/2 590) with a standardized rate of 12.8％.The rates of high TC,high TG,high LDL-C,low HDL-C and abnormal lipid metabolism among gender showed no statistically significant difference (P ＞ 0.05);② For both males & females,high TC rate,high TG rate,high LDL-C rate and total rate of abnormal lipid metabolism increased with age (P ＜ 0.01) while low HDL-C rate did not change with age (P ＞ 0.05);③Spearman's correlation analysis showed that the levels of TC,TG and LDL-C were positively correlated with BMI,WC,SBP,DBP,FBG,HbA1C and UA (all P ＜0.01) while the level of HDL-C had negative correlations with BMI,WC,SBP,DBP,FBG,HbA1 c,and UA (all P ＜ 0.05);④The total rate of abnormal lipid metabolism and various types of abnormal lipid metabolism increased with a rising level of BMI in the upward trend (trend test P ＜ 0.01),various types of abnormal lipid metabolism rate between different groups (elevated & non-elevated) of blood pressure,glucose and uric acid also were statistically significant (all P ＜ 0.05);⑤ Non-conditional logistic regression analysis showed that,after adjusting for age and gender,overweight or obesity and hypertension were risk factors of high TC and high LDL-C;overweight or obesity,hyperuricemia was a risk factor for low HDL-C;overweight or obesity,hypertension,hyperglycemia and hyperuricemia were risk factors for high TG and total abnormal blood lipid.Conclusions Urbanized community groups have a high rate of dyslipidemia.And abnormal lipid metabolism is affected by overweight or obesity,hypertension,hyperglycemia and hyperuricemia.The target population should be regularly monitored and comprehensively controlled.

Objective To explore the feasibility of repairing the large area skin and soft tissue defect in thefront upper of tibia by free flap with anastomosis of saphenous vessels.Methods From June,2009 to April,2014,16 cases (10 males and 6 females) of large area skin and soft tissue defect in the front upper of tibia were treatedwith free flap.The ages ranged from 24 to 56 years old,averaged of 34.5 years old.The supportive therapy and repeated debridement combined with VSD,and designed to use free anterolateral thigh flap with anastomosis of saphenous vessels before repairing operation.Results Fourteen patients accorded with preoperative design,in which 2 cases were adopted cross leg flap anastomosis posterior tibia vessels of the healthy side (1 case of saphenous artery diameter too small,and 1 case of saphenous artery long injury degeneration,unsuitable for vascular anastomosis).All 14 flaps survived,expect 2 cases were part-necrosis in the end of the flap,and gradually healed by dressing exchange.Conclusion Reconstruction of large area skin and soft tissue defect in the front upper of tibia with free flap can use anastomosis of saphenous vessels.

Objective To investigate the significance of immunostainning for Ber EP4and EMA in the diagnosis of basal cell carcinoma and squamous cell carcinoma of the skin.Methods Immunohisto-chemical stainning for Ber EP4and EMA was performed on115cases of basal cell carcinoma,squamous cell carcinoma,Bowen' s disease,actinic keratosis,basosquamous cell carcinoma,seborrheic keratosis,and verruca vulgaris.Specimens were taken from neoplastic tissues as well as the surrounding skin and ap-pendages.Results Ber EP4was positively stained in all cases of basal cell carcinoma and basosquamous cell carcinoma,but negatively stained in squamous cell carcinoma,Bowen's disease,actinic keratosis,sebor-rheic keratosis and verruca vulgaris.Expression of EMA was found in most cases of squamous cell carcinoma and Bowen' s disease,and a few cases of actinic keratosis,and in none of basal cell carcinoma,basosqua-mous cell carcinoma,seborrheic keratosis and verruca vulgaris.Conclusions Routine immunohistochemical staining with both Ber EP4and EMA is helpful for distinction of skin basal cell carcinoma,squamous cell carcinoma,precancerosis and benign hyperplastic dermatoses.

Objective To discuss the nursing care for patients with advanced hepatocellular carcinoma (HCC) who are receiving transcatheter arterial chemoembolization (TACE) combined with sorafenib. Methods A total of 23 consecutive patients with advanced HCC who met the inclusion criteria were enrolled in this study. TACE was carried out in all patients. Three-five days after TACE the patients started to orally take sorafenib. During the treatment course, the patients were kept under close observation for adverse reactions and complications. After leaving the hospital the patients were followed up by the extended care team members, and health education as well as appropriate nursing intervention was carried out. Results All patients with advanced HCC took sorafenib orally after TACE. The major adverse events and complications were gastrointestinal adverse reactions (n = 22) and transient liver dysfunction (n = 23). After leaving the hospital all the patients received regular follow- up examination and extended nursing care. Conclusion Usually, the incidence of adverse reactions is higher in patients with advanced HCC after TACE combined with sorafenib treatment. Careful in-hospital observation and extended out-hospital nursing can reduce the incidence of adverse reactions and thus improve the patient’s quality of life.
