AIM:To investigate whether ellagic acid (EA) attenuates hypoxic-ischemic encephalopathy (HIE) by down-regulating autophagy.METHODS:In vivo, Sprague-Dawley rats (n=17) were randomly divided into 3groups:5 rats for sham group, 6 rats for HIE group and 6 rats for HIE+EA pretreatment group.The rats in HIE+EA pretreatment group were treated with EA (10 mg/kg, 10 m L/kg, suspended in corn oil, ig).After 24 h of operation, the rats from each group were sacrificed and their brains were collected.TTC staining and HE staining were used to define the infarct areas and brain structure.The autophagy-related proteins beclin-1, P62, LC3-II/-I and Atg5 in the cortex in each group were compared by Western blot.In vitro, PC12 cells were divided into 3 groups:control group, Coand CoEA pretreatment group.Co800μmol/L was added to the PC12 cells to induce an anoxic environment.The PC12 cells were pretreated with EA at 8μmol/L and the cell viability was measured by CCK-8 assay.The production of reactive oxidative species (ROS) in the cells was detected by flow cytometry with DCFH-DA staining.MDC staining and TM-RE staining were applied to reflect the extent of autophagy and the state of apoptosis, respectively.The autophagy-related proteins in PC12 cells were also investigated.RESULTS:In HIE group, 7-day-old rats were given the operations and the their large infarct areas in the hemisphere were observed by TTC staining.HE staining displayed the injured hemispheres which contained few neurons, and exhibited edema status and serious structural damage.EA pretreatment decreased the infarct area and alleviated the damage to hemisphere with more visible neurons, compared with HIE group.Compared with sham group, the levels of autophagy-related proteins Atg5, beclin-1 and LC3-II/-I in the cortex were increased (P<0.01) , and P62 protein expression was decreased (P<0.01) in HIE group.Compared with HIE group, the protein expression of Atg5, beclin-1 and LC3-II/-I was decreased (P<0.01) and P62 protein expression was increased in HIE+EA pretreatment group (P<0.01).In vitro, compared with CoPC12 cells in CoEA pretreatment group showed a lower ROS level.Moreover, the cells in CoEA pretreatment group exhibited higher mitochondrial membrane potential than that in CoMDC staining in Coshowed high value of fluorescence and increased number of autophagosomes.EA pretreatment reduced the number of autophagosomes and the extent of autophagy to protect PC12cells.Furthermore, the protein levels of Atg5, beclin-1 and LC3-II/-I in Cowere higher (P<0.01) , and the protein expression of P62 was lower (P<0.01) than those in control group.In CoEA pretreatment group, the protein levels of Atg5, beclin-1 and LC3-II/-I were decreased (P<0.01) and the protein expression of P62 was increased as compared with Co (P<0.01).CONCLUSION:EA pretreatment attenuates autophagy to protect the neurons against HIE injury.

OBJECTIVETo evaluate the value of high-risk HPV (hrHPV) detection by Hybrid Capture II (HC2) in screening cervical intraepithelial neoplasm (CIN).

METHODSTotally 723 patients who had received a dual screening with thinprep cytologic test (TCT) and HC2 in our department were analyzed retrospectively. Among them, 350 patients received a triple examination with TCT, HC2, and colposcopic biopsy.

RESULTSAmong the 723 patients, the incidences of hrHPV infection with atypical squamous cell (ASC), low squamous intraepithelial lesion, and high squamous intraepithelial lesion were 70.7% (94/133), 88.9% (249/280), and 90.9% (90/99), respectively, significantly higher than 55.5% (117/211), the incidence of hrHPV infection with normal cytological results (P = 0.005, P < 0.001, P < 0.001, respectively). Among 350 cases who were received triple examination, the incidence of hrHPV infection with cervical intraepithelial neoplasia (CIN) 1 and CIN 2 were 88.9% (72/81) and 96.3% (52/54), significantly higher than 77.7% (153/197), the incidence of hrHPV infection with normal pathological results (P = 0.03, P = 0.002); The incidence of hrHPV infection with CIN 3 and squamous cancer were 91.7% (11/12) and 100.0% (6/6), also higher than normal cases. Among these 350 cases, the incidence of hrHPV infection with ASC was 79.3% (69/87). The incidence of CIN 2-3 with ASC and hrHPV infection was 38.0%, significantly higher than the incidence of CIN 2-3 with ASC and without hrHPV infection (5.9%) (P = 0.04).

CONCLUSIONhrHPV infection has a close relation with CIN, and the incidence of hrHPV infection increases along with the severity of CIN.

Objective:To describe the epidemiological distribution of hemorrhoids in a physical exami-nation population in China,which could provide evidence for precision prevention and early intervention of hemorrhoids.Methods:Chinese subjects over 18 years of age who underwent a physical examination in a nationwide chain of physical examination centers in 2018 were studied in a cross-sectional design,which collected information by a questionnaire and physical examination results from each subject.The epidemiological distribution of hemorrhoids was described using Logistic models.The gender-,age-,and region-detection rates of hemorrhoids were standardized to the Sixth National Population Census of the People's Republic of China(2010).Results:A total of 2 940 295 adult subjects were included in the study,of whom the average age was(41.7±14.0)years,and 52.6％were females.The standardized detection rate of hemorrhoids was higher for females(43.7％)than that for males(17.7％;P＜0.001)in this study.In the females,the age distribution of hemorrhoids was inverted U-shaped,with the highest standardized detection rate of hemorrhoids in the age group of 30-39 years(63.5％).In the males,the standardized detection rate of hemorrhoids increased along with age,with the highest percentage of 17.2％in the age group of 50-59 years,and the standardized detection rate of hemorrhoids in the age group of 60 and above decreased slightly(P＜0.001 for trend test).The participants with hypertension had a higher standardized detection rate of hemorrhoids than those with normal blood pressure in both males and females(P＜0.001).The standardized detection rate of hemorrhoids showed a positive corre-lation with body mass index(P＜0.001 for trend test in males).Conclusion:The detection rate of hemorrhoids varied to gender,age,obesity,and hypertension status,which could help to identify the risk factors and the high-risk sub-groups,and hence to strengthen health education and early detection accordingly,which could eventually reduce the incidence of hemorrhoids and improve the quality of life and health in the Chinese population.This study was conducted in a physical examination population,and the conclusions of this study should be extrapolated with caution.

To explore famous veteran traditional Chinese medicine( TCM) doctors' medication rules in treating spermatorrhea based on the medical cases about spermatorrhea collected from Hundred TCM Clinical Doctors of Hundred Years in China and Proven Cases and National Medical Master Test Case. Researchers extracted such data as medicinal and therapies from these cases according to the inclusion and exclusion criteria. Then,Excle 2010,SPSS Clementine 12. 0 and SPSS 22. 0 were adopted respectively for frequency analysis,association rules analysis,cluster analysis and factor analysis. Cluster analysis was carried out by Ochiai algorithm of binary variable data,one of the systematic clustering methods. And principal component analysis was used for factor analysis. Finally,27 medical cases and 41 prescriptions were included in total. The frequency analysis showed that the most common therapy was the astringent therapy( n = 28),which was followed by the tonifying method,tranquilizing method,heat-clearing method,damp-dispelling method and Qiregulating method. The top three kinds of high-frequency traditional Chinese medicines were Poria,Ostreae Concha and Dioscoreae Rhizoma. The association rules analysis found out 11 association rules of medicine pairs,23 association rules of medicine combinations of the three kinds of herbs and 6 association rules of medicine combinations of five kinds of herbs. Among them,the representatives were Rubi Fructus→Fossilia Ossis Mastodi,Rehmanniae Radix Praeparata + Corni Fructus→Dioscoreae Rhizoma,and Pinelliae Rhizoma→Citri Reticulatae Pericarpium,which showed the therapeutic characteristics of astringing,tonifying the kidney and replenishing essence,fortifying the spleen and dispelling dampness. Moreover,7 medicine groups with relevance were extracted from the tree map generated by cluster analysis,including " Phellodendri Chinensis Cortex and Anemarrhenae Rhizoma" and " Angelicae Sinensis Radix,Rehmanniae Radix,Bupleuri Radix and Glycyrrhizae Radix et Rhizoma",which demonstrated the effects of nourishing Yin and purging fire,tonifying and soothing the liver. Besides,totally 12 common factors were obtained according to factor analysis,including 14 drug combinations,like " Amomi Fructus,Anemarrhenae Rhizoma and Phellodendri Chinensis Cortex" and " Nelumbinis Stamen,Moutan Cortex,Poria and Scrophulariae Radix",which indicated the compatibility characteristics of tonifying the spleen and purging fire,dispelling dampness and clearing heat. In conclusion,data mining techniques( including frequency analysis,association rules analysis,cluster analysis and factor analysis) were used to comprehensively analyze the famous veteran TCM doctors' medication rules in treating spermatorrhea,which was helpful for guiding the clinical practice of treating spermatorrhea in TCM.
