Objective In order to know the effect of rehabilitation of pelvic organs by pelvic floor muscle training and electrical stimulation. Methods Divided 330 pregnant women into the integrated group(120 cases),the experimental group(100 cases) and the control group(100 cases) randomly. Rou-tine nursing cares was used in the control group, pelvic floor muscle training and electrical stimulation were used in the integrated group in addition, pelvic floor muscle training was used in the experimental group. Evaluated the rehabilitation condition of pelvic organs in the 42nd day after delivery among the three groups. Results All the indexes which can indicated the rehabilitation condition of pelvic or-gans in the integrated group and the experimental group were significant better than those of in the con-trol group, while there was no significant differences about the above indexes between the integrated group and the experimental group. Conclusions Pelvic floor muscle training combined with electrical stimulation can effective promote the rehabilitation of function of pelvic organs, and then prevent the in-cidence of related diseases.

The purpose of this study is to develop glipizide push-pull osmotic pump (PPOP) tablets by using a formulation design expert system and an artificial neural network (ANN). Firstly, the expert system for the formulation design of osmotic pump of poor water-soluble drug was employed to design the formulation of glipizide PPOP, taking the dissolution test results of Glucotrol XL as the goal. Then glipizide PPOP was prepared according to the designed formulations and the in vitro dissolution was carried out. And in vivo evaluation was carried out between the samples which were similar to Glucotrol XL and the Glucotrol XL in Beagle dogs. The range of the factors of formulation and procedure, which could influence the drug release, was optimized using artificial neural network. Finally, the design space was found. It was found that the target formulation which was similar to Glucotrol XL in dissolution test could be obtained in a short period by using the expert system. The samples which were similar to Glucotrol XL were bio-equivalent to the Glucotrol XL in Beagle dogs. The design space of the key parameter coating weight gain was 9.5%-12.0%. It could be concluded that a well controlled product of glipizide PPOP was developed since the dissolution test standard of our product was more strict than that of Glucotrol XL.

OBJECTIVE: To valuate test results of normal hearing persons with different ages using disyllabic mandarin speech test materials (MSTMs). Obtaining speech recognition threshold (SRT) and P-I function of different ages as clinical reference of hearing recovery and individual's ability to perceive and process speech. METHOD: One hundred and twenty subjects with normal hearing who speak mandarin well in their daily lives were enrolled in this study and divided into four groups (18-30, 31-40, 41-50 and 51-60 years old). Nine lists of disyllabic mandarin speech test materials with equal difficulty were utilized to test each age group. RESULT: There are good agreement between SRT and mean PTA thresholds (at 0.5, 1.0, 2.0, and 4.0 kHz) in each age group. PTA thresholds have little change as age increasing in age group 18-30, 31-40 and 41-50 (P > 0.05). PTA threshold of age group 51-60 increases more apparently compared with the other three groups (P < 0.01). SRT thresholds of each age group increase as age increasing (P < 0.05) and SRT threshold of age group 51-60 increases more apparently (P < 0.01). Slopes of P-I function in each age group are 5.8%/dB, 4.7%/dB, 3.8%/dB, 2.9%/dB respectively. CONCLUSION Nine lists of disyllabic MSTMs were used to test normal hearing persons in different ages and SRT and P-I function of four different age groups were obtained. As age increases, SRT increases and slope of P-1 functions decreases. PTA and SRT thresholds of age group 51-60 increase more apparently. The SRT and P-I functions provide reference data of normal hearing for utilizing of disyllabic mandarin speech test materials clinically.

ObjectiveTo analyze the expression level of triggering receptor expressed on myeloid cells-1 （TREM-1） in serum and ascites of patients with cirrhotic ascites， and to investigate its correlation with clinical features and inflammatory markers and its role in the diagnosis of infection and prognostic evaluation. MethodsA total of 110 patients with cirrhotic ascites who were hospitalized in The Fifth Hospital of Shijiazhuang from January 2019 to December 2020 were enrolled， and according to the presence or absence of intra-abdominal infection， they were divided into infection group with 72 patients and non-infection group with 38 patients. The patients with infection were further divided into improvement group with 38 patients and non-improvement group with 34 patients. Clinical data and laboratory markers were collected from all patients. Serum and ascites samples were collected， and ELISA was used to measure the level of TREM-1. The independent-samples t test was used for comparison of normally distributed continuous data between two groups； the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups， and the Kruskal-Wallis H test was used for comparison between multiple groups； the chi-square test was used for comparison of categorical data between two groups. A Spearman correlation analysis was used to investigate the correlation between indicators. A multivariate Logistic regression analysis was used to identify the influencing factors for the prognosis of patients with cirrhotic ascites and infection. The receiver operating characteristic （ROC） curve was used to evaluate the diagnostic and prognostic efficacy of each indicator， and the Delong test was used for comparison of the area under the ROC curve （AUC）. ResultsThe level of TREM-1 in ascites was significantly positively correlated with that in serum （r=0.50， P<0.001）. Compared with the improvement group， the non-improvement group had a significantly higher level of TREM-1 in ascites （Z=-2.391， P=0.017） and serum （Z=-2.544， P=0.011）， and compared with the non-infection group， the infection group had a significantly higher level of TREM-1 in ascites （Z=-3.420， P<0.001）， while there was no significant difference in the level of TREM-1 in serum between the two groups （P>0.05）. The level of TREM-1 in serum and ascites were significantly positively correlated with C-reactive protein （CRP）， procalcitonin （PCT）， white blood cell count， and neutrophil-lymphocyte ratio （r=0.288， 0.344， 0.530， 0.510， 0.534， 0.454， 0.330， and 0.404， all P<0.05）. The ROC curve analysis showed that when PCT， CRP， and serum or ascitic TREM-1 were used in combination for the diagnosis of cirrhotic ascites with infection， the AUCs were 0.715 and 0.740， respectively. The multivariate Logistic regression analysis showed that CRP （odds ratio ［OR］=1.019， 95% confidence interval ［CI］： 1.001‍ ‍—‍ ‍1.038， P=0.043） and serum TREM-1 （OR=1.002， 95%CI： 1.000‍ ‍—‍ ‍1.003， P=0.016） were independent risk factors for the prognosis of patients with cirrhotic ascites and infection， and the combination of these two indicators had an AUC of 0.728 in predicting poor prognosis. ConclusionThe level of TREM-1 is closely associated with the severity of infection and prognosis in patients with cirrhotic ascites， and combined measurement of TREM-1 and CRP/PCT can improve the diagnostic accuracy of infection and provide support for prognostic evaluation.
