Objective To evaluate the detection of membrane neutrophil alkaline phosphatase (NAP)in diagnosis of infection in patients with acute cerebral hemorrhage.Methods A total of 208 patients with acute cerebral hemorrhage,including 1 52 cases without infection (uninfected group)and 56 cases with infection (infected group),admitted in the Second Affiliated Hospital of Nantong University during January 201 0 to July 201 6 were enrolled,30 healthy subjects were also enrolled in the study as control group.The peripheral blood from all subjects were collected,and the counts of white blood cell (WBC), percentage of neutrophil,serum procalcitonin (PCT)and NAP were measured.The value of above 4 indicators in diagnosing infection was determined by receiver operating characteristic (ROC ) curves. ANOVA and t test were used to analyze the data,Pearson correlation was performed to analyze the correlation between NAP and PCT in infected group.Results The levels of WBC,percentage of neutrophil and NAP in both infected and uninfected group were higher than those in healthy control group at admission(F =1 1 7.64, 1 00.69 and 425.09,all P <0.01 ),and the levels of WBC,PCT and NAP were also higher when infection occurred compared with those at admission in infected group (t =3.1 4,34.30 and 36.39,all P <0.01 ). The expression of NAP was positively correlated with PCT in infected group (r =0.762,P <0.05).ROC curve analysis showed that the areas under the curves of NAP and PCT in diagnosis of infection were 0.875 and 0.884,respectively.When 1 0655.28 AB/c and 5.01 mg/L were taken as cut-off values,the sensitivities of NAP and PCT in diagnosis of infection were 85.50% and 87.66%;the specificities were 90.50%和 90.31 %,respectively.The level of NAP in infected patients with gram-positive bacterial infections was higher than that in patients with gram-negative bacterial infections (t =6.29,P <0.01 ). Conclusion The expression of NAP in patients with acute cerebral hemorrhage increases when infection occurs,which may be helpful to the clinical diagnosis of bacterial infection.

The traditional clinical trail designs always depend on expert opinions and lack statistical evaluations. In this article, we present a method and illustrate how population parameter uncertainty may be incorporated in the overall simulation model. Using the techniques of clinical trail simulation (CTS) and setting up predictions on the basis of pharmacokinetics-pharmacodynamics (PK-PD) models, we advance the modeling methods for simulation, for treatment effects, and for the clinical trail power under the given PK-PD conditions. Then we discuss the model of uncertainty, suggest an ANOVA-based method, add eta2 statistics for sensitivity analysis, and canvass the effect of uncertainty about population parameters on clinical trail power. The results from simulations and the indices derived from this type of sensitivity analysis may be used for grading the influence on the prediction quality of uncertainty about different population parameters. The experiment results are satisfactory and the approach presented has practical value in clinical trails.

Objective To understand the epidemiological characteristics of patients with advanced schistosomiasis in Hunan Province,so as to provide the evidence for formulating the advanced schistosomiasis prevention strategies and measures. Meth-ods The data of advanced schistosomiasis patients were collected and analyzed retrospectively with the cross section research method and description method in Hunan Province,2012. Results There were 5 722 advanced schistosomiasis patients in Hu-nan Province,and among them,4 112 patients were male(71.86%),and 1 610 were female(28.14%). Totally 5 311 patients came from the schistosomiasis endemic areas(92.82%)and 411 patients from non-schistosomiasis endemic areas(7.18%). The prevalence rate of advanced schistosomiasis was 8.46/10 000. The mean age of advanced schistosomiasis patients was 60.30 ± 11.63 years,and the youngest was 17 years old and the oldest 92 years old. In the age composition of advanced schistosomiasis pa-tients,the greatest number of cases was in the 60-70 years age group (32.72%). There were 3 595 cases of ascites type (62.83%),2107 cases of splenomegaly type(36.82%),11 cases of dwarf type(0.16%),and 11 cases of colon proliferation type (0.35%). Conclusion The prevalence rate of advanced schistosomiasis is relatively stable in Hunan Province,and the age of the patients showed an old aging trend. The salvation of advanced schistosomiasis patients in non-endemic areas should be strength-ened.

Embryos with a poor morphological score at cleavage stage are usually discarded because they are considered unsuitable for transfer and cryopreservation. This study examined the in vitro blastocyst development after extended culture of these embryos and the clinical outcomes after transfer of these blastocysts in warming cycles. A total of 597 blastocysts (24.7%) were obtained from 2421 embryos with low morphological scores after extended culture. One hundred and sixty blastocysts (6.6%) with optimal morphology were vitrified. Embryo utilization rate was increased from 30.8% to 32.6%. After warming, 61 out of 92 blastocysts (66.3%) survived and were transferred in 44 cycles. The clinical pregnancy rate and the implantation rate were 40.9% (18/44) and 32.8% (20/61) respectively. Thirteen healthy babies were born, and 5 pregnancies aborted spontaneously. Our study suggested that some blastocysts derived from embryos with a poor morphological score can be successfully vitrified and give rise to live births. Selection and vitrification of viable embryos after extended culture of embryos with a poor morphological score may constitute a proposal to avoid embryo wastage.

To assess the relationship between pronuclear scoring and day-3 embryo quality and pregnancy outcome and to determine the clinical value of pronuclear stage scoring system in human in vitro fertilization-embryo transfer (IVF-ET) program, a pronuclear scoring system was used to score zygotes 16-20 h after insemination during conventional IVF or intracytoplasmic sperm injection (ICSI). The embryos were classified into groups Z1, Z2, Z3 and Z4. Comparisons were made of the rates of arrested embryos and excellent embryos on day 3. Comparisons of pregnancy outcome were made only in those patients in whom cohorts of similarly Z-scored embryos were transferred. The results showed that there were less arrested embryos and more excellent embryos on day 3 in groups Z1 and Z2 than those in group Z3 and Z4. More embryos arrested and less excellent embryos developed in group Z4 than group Z3. The clinical pregnancy rates resulting from the transfer of single pronuclear score homologous embryo types were similar among groups Z1, Z2 and Z3. Implantation rates of group Z1 were higher (P<0.05) than that of group Z3. These findings suggests that pronuclear scoring can predict developmental ability on day 3 and implantation potential. A evaluation that combines the Z-score and day 3 embryo morphology is useful in the determination of the most viable embryos and the number of embryos for transfer.

Objective:To assess the urethral mobility of normal parous women in China and explore the impacts of related risk factors on it using translabial ultrasound.Methods:Females who met the inclusion criteria in 37 tertiary hospitals from February 2017 to August 2018 were included. All women underwent standardized translabial ultrasound examination and the urethral rotation angle (URA), bladder neck position at maximum Valsalva maneuver (BNP-V) and bladder neck descent (BND) were measured. Questionnaires were used to collect basic information including age, height, weight, body mass index (BMI), past medical history, maternity history, and urinary incontinence related history. Mann-Whitney U test and multiple linear regression analysis were adopted to explore the influences of age, BMI, delivery mode and parity on normal parous women′s urethral mobility. Then, the study subjects were divided into different groups and the corresponding values of URA, BNP-V and BND were compared. Results:Compared with parous women with normal BMI and no history of vaginal delivery, those who were overweight and/or had a history of vaginal delivery were more likely to gain greater URA and BND ( P<0.05). The URA and BND were not significantly different between women with different times of cesarean sections ( P>0.05); while for women with a history of vaginal delivery, these two parameters increased with the increase of the number of transvaginal deliveries ( P<0.05). Conclusions:BMI and vaginal delivery are important risk factors for the urethral mobility of normal parous women. The urethral mobility increases with the increase of BMI and the number of vaginal deliveries.
