ObjectiveTo observe the effects of Baihe Yuzi prescription （BYP） on the cystic fibrosis transmembrane conductance regulator （CFTR）， aquaporin （AQP）， zinc/iron-regulated transporter-like protein （ZIP） and local oxidative stress in epididymis of oligoasthenozoospermia （OAS） rats， and to explore the mechanism of its intervention in OAS. MethodAfter 35 rats were acclimatized for 1 week， 7 rats were randomly selected as the normal group， and the remaining 28 rats were given tripterygium glycosides （TG） 30 mg·kg^-1. After 4 weeks of modeling， they were randomly divided into 4 groups： model group， BYP low-dose group （LBYP）， BYP high-dose group （HBYP） and levocarnitine group， with 7 rats in each group. The rats in the normal group and model group were given normal saline at the same dosage. The levocarnitine group rats were given L-carnitine oral liquid （100 mg·kg^-1） by gavage. The LBYP group rats were given BYP 6.3 g·kg^-1， and the HBYP group rats were given BYP 12.6 g·kg^-1 by gavage once a day for consecutive 4 weeks. After the end of the intervention， sperm count and motility of all rats were detected， the histopathological structure of epididymis was observed by hematoxylin-eosin （HE） staining， and the expressions of CFTR， AQP9， AQP3， ZIP8， ZIP12 and other proteins were detected by Western blot. The contents of α-glycosidase （α-GC）， sialic acid （SA）， carnitine， superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px） and malondialdehyde （MDA） were detected by enzyme-linked immunosorbent assay （ELISA）. Total zinc content was measured using an inductively coupled plasma mass spectrometer. Free zinc ion content was detected by zinc ion probes. ResultCompared with those in the normal group， the sperm count and motility of rats were decreased and the epididymal structure was disordered in the model group. The contents of α-GC and carnitine were decreased in epididymis （P<0.05）. MDA levels were increased， while SOD， GSH-Px and zinc levels were decreased （P<0.05）. The expressions of CFTR and ZIP12 in the head and cauda of the epididymis were down-regulated， and AQP3 expression was up-regulated. The expression of ZIP8 in the cauda epididymis was up-regulated （P<0.05）. Compared with the model group， BYP can significantly improve the sperm count and motility， the epididymal structure of OAS rats and the levels of α-GC and carnitine （P<0.05）. The expressions of CFTR and ZIP12 in the head and cauda of the epididymis were up-regulated， while the expressions of ZIP8 in the cauda epididymis and AQP3 in the head of the epididymis were decreased （P<0.05）. The SOD and GSH-Px levels and total zinc content in epididymis were increased， and the MDA levels were decreased （P<0.05）. ConclusionBYP may improve the sperm quality and repair epididymal tissue structure and function of OAS rats， by regulating the expressions of CFTR， AQP3， and ZIP12 ion channels and local antioxidant mechanism.

Objective: To investigate the mediating effects of resilience and emotion regulation on family cumulative risk and positive coping style among primary and middle school students, so as to provide insights into promoting psychological health among them. Methods: The primary and middle school students from three counties (districts) of Baise City, Guangxi Zhuang Autonomous Region were selected through the stratified cluster random sampling method. Resilience, emotion regulation, family cumulative risk and positive coping style were investigated using the Resilience Scale for Chinese adolescent, Emotion Regulation Questionnaire, Chinese family Assessment Instrument, and Simple Coping Strategies Questionnaire, respectively. Mediating effects of resilience and emotion regulation on family cumulative risk and positive coping style were examined using Process macro program. Results: Totally 1 076 questionnaires were allocated, and 1 006 valid questionnaires were recovered, with an effective rate of 93.49%. There were 515 boys, accounting for 51.19%. The median age was 13 (interquartile range, 1) years. The mean scores of resilience, emotion regulation and positive coping style were (3.36±0.63), (2.26±0.56) and (1.85±0.39) points, respectively. The median family cumulative risk index was 0 (interquartile range, 0). The results of mediating effects showed that family cumulative risk had a direct negative effect on positive coping style (β=-0.037, 95%CI: -0.059 to -0.014, P=0.011), and also had an indirect negative effect on positive coping style through psychological resilience (β=-0.029, 95%CI: -0.041 to -0.017, P=0.006) as a mediator or through psychological resilience and emotion regulation (β=-0.002, 95%CI: -0.004 to -0.001, P=0.001) as a chain mediator. The mediating effect of resilience contributed 44% to the total effect, while the chain mediating effect of resilience and emotion regulation contributed 3%. Conclusion Resilience and emotional regulation serve as negative mediators between family cumulative risk and positive coping style among middle and primary school students.

Zinc is an important regulator of various biological processes such as protein synthesis,cell proliferation,migration and autophagy.The zinc transporter ZIP13(SLC39A13)is a homodimeric metal transporter functioning in transport of zinc,iron,and calcium plasma in body.ZIP13 is involved in disease by regulating zinc homeostasis,such as the key role of ZIP13 in connective tissue development because it is involved in the BMP/TGF-β signaling pathway.ZIP13 promotes the metastasis of human ovarian cancer cells by activating the Src/FAK signaling pathway and ZIP13 inhibits the biogenesis and energy expenditure of beige adipocytes by regulating C/EBP-β expression.

Objective To explore the value of contrast-enhanced ultrasound ( CEUS) in evaluating the effect of liver cancer ablation. Methods A total of 46 patients with liver cancer (60 lesions) were treated with microwave ablation between May 2008 and October 2016.After 1 month, color Doppler flow imaging ( CDFI), contrast-enhanced CT ( CECT) and CEUS examinations were performed.A biopsy was performed on each of positive lesions . Results A total of 12 positive lesions were detected by CECT , and the biopsy proved to be residual tumor .A total of 11 lesions were detected by CEUS (the rate of missed diagnosis was 8.3%, 1/12). In CEUS positive lesions, 8 lesions were detected by CDFI (the rate of missed diagnosis was 33.3%, 4/12).There were no false positives. Conclusions Application of CEUS to evaluate the effect of liver tumor ablation is simple , reliable, and non-radiative.It has obvious advantages in follow-ups after liver tumor ablation and guided biopsy and treatment of residual lesions .

OBJECTIVEDynamic changes of quality and growth of Whitmania pigra were investigated to provide theoretical basis for quality control and determination of optimal harvest time.

METHODThe contents of moisture, ethanol-soluble extractive, total ash, and acid-insoluble ash, as well as antithrombin activity were determined according to Chinese pharmacopoeia (2005 edition).

RESULTQualities of W. pigra collected from different growth stages met the standards of Chinese pharmacopoeia (2005 edition). The highest amount of ethanol-soluble extract was found in 9-month-old, W. pigra, followed by 6-month-aged ones. And there was significant difference between 9-month-old and 4-month-old, 7 month-old and 11 month-old (P < 0.05). The highest antithrombin activity was detected in 6 month-old W. pigra, followed by 10 month-old. Significant differences of antithrombin activity were found between 6-month-old and 4 month-old ones, and 5 month-old (P < 0.05), however, there were no significant difference between 6 month-old ones with other samples. Eleven-month-old W. pigra got the most dry weight, and there were significant difference between 11 month-old ones with other samples (P < 0.05).

CONCLUSIONNovember, namely for 6 month old artificial cultivated W. pigra was the best harvest time in Jiangsu and Zhejiang provinces.
