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 evaluate pharmacokinetic and pharmacodynamic of repaglinide tablets in Chinese subjects.Methods: Twenty healthy male volunteers were enrolled in the study. A single dose (4 mg) of repaglinide tablets was givenorally. Plasma concentrations of repaglinide were determined by HPLC method. Blood glucose and serum insulin leve1s weremeasured by biochemistry and radioimmunoassay methods respectively. Results: Plasma concentration-time curve conformedto one-compartment open model. The pharmacokinetic parameters were as follows: tmax (0. 75?0.43 ) h,cmax (54.44?24.97)ng/ml, t1/2 (0. 80?0. 31) h, MRT (1. 55?0. 41) h, C1/F (61. 43?20. 10) L/h and AUC (73. 34?29.95) h? ng/ml. Thelevel of serum insulin was raised and the level of blood glucose decreased after administration of repaglinide. The highest levelof serum insulin was (l26. 24?95.93) mU/L at 0.75h and blood glucose level reached its lowerest vaIue (2. 34I0.44) mmol/L 1 h after oral administration. Conclusion: Repaglinide is characterised by fast-acting and short effects on in-sulin secretion. It decreases serum glucose level by stimulating insulin secretion from the pancreatic ?-cells. It is a novel oralprandial glucose regulator for the treatment of type 2 diabetes mellitus.

Objective:To evaluate bioequivalence and relative bioavailability of domestic and imported repaglinide tablets in healthy volunteers. Methods: Twenty two healthy male volunteers were randomized into A and B groups. A single dose (4 mg) of domestic and imported repaglinide tablets were given respectively according to an open 2-way crossover study design. The washout period was 1 week. Plasma concentrations of repaglinide were determined by HPLC method. Results:The pharmacokinetic parameters of domestic and imported drugs were as follows: t1/2 were(0.86±0.24) and (0.83±0.31) h;tmax were( 0.79±0.37) and (0.75±0.41) h;cmax were (52.43±20.92) and (53.32±24.94) μg/L. AUC0-t were (79.87±36.48) and (74.95±30.57) μg*h*L-1,respectively. The relative bioavailability of domestic formulation was (106.55±16.15)%. Conclusion: The results of variance analysis and two one-side t test show that 2 formulations are of bioequivalence.

Objective To analyze the advantages of modified retrograde endotracheal intubation and to investigate its application effect in difficult airway opening. Methods Eighteen patients with difficult airways receiving modified retrograde endotracheal intubation admitted to Jinhua Municipal Central Hospital from June 2013 to June 2017 were enrolled. The successful intubation rate, complication rate, average intubation time and typical cases were calculated and analyzed. Results The causes of airway difficulty in 18 patients: there were 7 patients with glottis exposing difficulty due to tongue body hypertrophy, 2 patients with trismus due to tetanus, 5 patients with cervical spinal cord injury and 4 patients with burns. The successful rate of modified retrograde endotracheal intubation was 100% in 18 patients with difficult airway. Only 1 patient had a little bleeding at the puncture site and it was improved after local compression, the complication rate being 5.6% (1/18), and the average intubation time was (3.6±0.8) min. Conclusion Modified retrograde endotracheal intubation is a method easy to be mastered, its material is simple and easily to be acquired, clinically, the successful rate in its application in difficult airway patients is very high and its incidence of complication is very low, so that the technique can be popularized in primary hospitals.

OBJECTIVETo determine the cause of acute poisoning occurred in a factory in Yangjiang city, Guangdong province.
METHODSIn a cross-sectional study, interviews were conducted with the administrators of the factory and the local physician. A review was conducted on the water system used for industrial purposes and a separate system used by workers for drinking water. Treatment and discharge of industrial waste water were examined. Face-to-face interview was conducted to identify risk of exposure for illness among workers.
RESULTSA total number of 36 cases were identified in the plant and the attack rate was 16.4% (36/220). The incubation period (time between drinking polluted water and the onset of symptoms) had a median of 90 minutes (range: 30 - 230 minutes). Consuming water at the factory increased the attack rate and a dose-response effect was identified (chi(2)(trend) = 79.115, P < 0.01). The nitrite content of residuals in drinking water exceeded the WHO standard (1 ppm).
CONCLUSIONSThe accident of acute poisoning was due to drinking water contaminated with sodium nitrite. The prevention of drinking water contaminated by toxic chemicals like sodium nitrite, and the design of industrial and potable water supply system need to be carefully reviewed. Regulations should be developed and enforced to minimize the impact of industrial waste water discharges to guarantee the access to clean drinking water.

Objective To explore the value of 18F-FDG PET/CT in diagnosis of retroperitoneal fibrosis (RPF).Methods Totally 12 RPF patients underwent 18 F-FDG PET/CT scanning,and the characteristics of metabolic activity,distribution of retroperitoneal lesions and maximum standardized uptake value (SUVmax) were analyzed retrospectively.Results Among 12 patients,7 were initial evaluation patients,5 were post-treatment patients.Of 7 initial evaluation patients,there were 4 patients with secondary RPF,including prostate carcinoma,breast cancer and IgG4-related disease.Retroperitoneal mass isodense with muscle surrounding the abdominal aorta or the iliac arteries were found in 12 patients,and ureteral involvement were found in 11 paients (11/12,91.67%).SUVmax in initial evaluation patients (4.21±1.76) was higher than that in patients after treatment (1.46±0.25,P<0.05).According to PET/CT,3 idiopathic RPF patients as initial evaluation with high metabolic activity lesions received immunosuppressive therapy including corticosteroids and tamoxifen,and 4 secondary RPF patients with high metabolic activity lesions received treatment based on causes.Among 5 post-treatment patients,3 continued to accept current corticosteroids maintenance dose,while 2 did not receive any other treatment.Conclusion PET/CT may be used to evaluate the activity and extension of lesions in patients with RPF.

OBJECTIVE:
To determine the biological activity of ellagic acid extracted from gallnut against nasopharyngeal carcinoma and its molecular mechanism.
METHODS:
Nasopharyngeal carcinoma 5-8F cells were treated with 2, 4, 6 μg/mL ellagic acid for 48 h in vitro. The cell proliferation and cell apoptosis were analyzed by MTT and Hoechst33258 stain. The cell cycle and protein expression were measured by flow cytometry and Western blot.
RESULTS:
Ellagic acid inhibited the proliferation of 5-8F cells. The inhibition rates were (29.35±4.95)%, (53.32 ±4.44)% and ( 61.75 + 6.93)%, respectively, with significant difference from the control group (P<0.01). S phase cells in the experimental groups were (25.47±0.74)%, (28.08±1.41)% and (35.49±0.66)%, respectively, with significant difference (P<0.01) from the control group (21.26±0.70)%. Cells in the experimental groups showed nuclear pyknosis, karyorrhexis and poptotic cell morphology. The expression of COX-2 and stathmin in 5-8F cells was down-regulated with increased drug concentration.
CONCLUSION
Ellagic acid extracted from gallnut has activity against nasopharyngeal carcinoma cells, and its mechanism may be related to down-regulated expression of COX-2 and stathmin.
