A reversed phase high-performance liquid chromatography method for the simultaneous analysis of 23 kinds of phenolic components in water extract of porpolis (WEP) was developed. The separation was performed on ZORBAX Eclipse XDB C_(18) column (150 mm×4.6 mm, 5 μm) by gradient elution. The mobile phase consisted of ethanol with 0.1% formic acid at the flow rate of 1.0 mL/min. The detection wavelengths were 256 and 280 nm. The injection volume was 20 μL, and the column temperature was maintained at 35 ℃. The method showed good linear relationship, precision and repeatability. The recoveries were between 93.3% and 106.6%. Eighteen Reference compounds were detected in WEP of Hehei by this method. The content of Catechin was the highest(30.50 mg/g), the next was 3,4-dimethoxycinnamic acid (15.41 mg/g). Nine Reference compounds were detected in WEP of Yunnan. The content of catechin was also the highest (11.23 mg/g), the next was chrysin (15.41 mg/g). Similarity of WEPs between the products of Hebei and Yunnan were 0.099 (256 nm) and 0.194 (280 nm). The chemical compositions of two WEPs were remarkably different.

ObjectiveTo observe the dynamics of antibodies and protection against Schistosoma japonicum infections in buffaloes after immunized with recombinant 26 kDa glutathione S transferase (reSjc26GST). Methods Buffaloes in 2 villages endemic for schistosomiasis japonica were selected as test and control groups, respectively.In test group initially 96 buffaloes were vaccinated with reSjc26GST, and 90 buffaloes in the control group did not experience vaccination. The indicators included levels of antibodies to reSjc26GST in buffaloes before and after infection with S japonicum and changes in infection rate. Results Specific antibodies, which showed a trend of trapezoid increase, were induced in buffaloes after immunized with reSjc26GST. Twenty months after immunization, the infection rate of the test group was decreased by 62 2% when compared with that before vaccination,and by 67 7% when compared with that of the control in the corresponding period.Conclusion Specific antibodies and a certain extent of protection were induced in buffaloes after immunized with reSjc26GST, which played an significant role in ameliorating morbidity.

With the improvement of living standard, the incidence rate of nonalcoholic fatty liver disease (NAFLD) is gradually increasing year by year and its age of onset tends to become younger, but its pathogenesis remains unclear. Macrophages are important cells involved in the pathogenesis of NAFLD and have attracted great attention. This article elaborates on the origin and classification of liver macrophages, the role of macrophages in liver inflammation and related activation mechanism, and the drugs targeting macrophages, in order to provide a reference for the clinical treatment of NAFLD.

[Objective] The present study aimed to determine the protective role of Melatonin (MT) against Acrylamide (AA)-induced testicular toxicity and the potential molecular mechanism.[Methods] The animals were randomly divided into three groups,the control group (n =12),the AA group (n =12) and the AA+MT group (n =12).The rats in the AA and AA + MT group were gavaged with AA at a dose of 15 mg/(kg · day) for 4 consecutive weeks.After 3 weeks of AA treatment,MT was intraperitoneally injected 30 minutes before AA treatment at 10 mg/(kg· day) for 1 week in the AA + MT rats.Subsequently,the mitochondrial membrane potential measurement,TUNEL assay,Western blot and electron microscopic techniques were applied in the present study.[Results] The results showed that AA could decrease the testis mitochondrial membrane potential (P ＜ 0.05) which could be recovered by MT (P ＜ 0.05).Moreover,MT induced down-regulation of Bax expression and up-regulation of Bcl-2 expression in the testis,compared with AA rats.The amelioration of testicular apoptosis was further confirmed by the TUNEL labeling.Western blot results suggested that the decreased ratios of Bcl-2/Bax and Bcl-xL/Bak in the AA group (both P ＜ 0.05) could be recovered by MT treatment (both P ＜ 0.05).The levels of Cyt-c,Casp-3,p53 and NF-κB in AA group were markedly elevated compared with the control (all P ＜ 0.05),and reduced in MT treatment group (all P ＜ 0.05).MT could relieve abnormal mitochondrial structures in the seminiferous tubule in the electron microscopic level.[Conclusion] MT may exert productive effect through its anti-apoptotic properties associated with mitochondria.

Objective To investigate the association of PR gene exon 5 region H770H (rs1042839) single nucleotide polymorphism (SNP) with the genetic susceptibility to endometriosis (EM) in southern Han Chinese women. Methods Totally 431 EM patients and 499 non-EM women were collected and separated into EM group and control group, that all cases were confirmed by operation and pathology. A case-control study was performed in EM and control groups to evaluate the association of these SNP with the susceptibility to EM by using a fluorescent quantitative PCR-based high resolution melting (HRM) method. Results The C and T of PR H770H allele frequencies among the EM and control groups were 97.9%(844/862), 2.1% (18/862) and 99.4% (992/998), 0.6% (6/998), respectively. The CC, CT and TT of PR H770H genotype frequencies among the EM and control groups were 95.8%(413/431), 4.2%(18/431), 0 and 98.8%(493/499), 1.2%(6/499), 0, respectively. There were statistical significances in the PR H770H alleles and genotypes distributions between the two groups (χ2=7.386, P=0.007;χ2=8.135, P=0.004). Carrying allele C reduced the risk of EM (OR=0.986, 95%CI: 0.976-0.996), while carrying allele T enhanced the risk of EM (OR=3.319, 95%CI: 1.323-8.325); carrying genotype CC reduced the risk of EM 0.970 time (OR=0.970, 95%CI: 0.949-0.991), whereas carrying genotype CT enhanced the risk of EM 3.473 times (OR=3.473, 95%CI:1.391-8.671). Conclusion There is significant association between the polymorphism of PR H770H and genetic susceptibility to EM in southern Han Chinese women.

Objective: To explore the effects of macrophages with high expression of TL1A on the activation and proliferation of HSCs in vitro. Methods: The Bone marrow-derived macrophages (BMMs) and peritoneal macrophages (PMs) from wild type (WT) and myeloid-overexpressed TL1A transgenic mice were isolated, differentiated and activated. HSCs were harvested from activated macrophages culture supernatant (CM). HSCs were detected by immunofluorescence and real-time Q-PCR. And the proliferation was detected by CCK-8 and BrdU assay kit. The levels of IL-1β and PDGF-BB in macrophage culture supernatants were determined by enzyme-linked immunosorbent assay (ELISA). Results: BMMs-derived CM-intervention HSCs were used to detect the expression of α-smooth muscle actin (α-SMA) on the 2nd, 4th and 6th day respectively by immunofluorescence method. There was no significant difference between the two groups on the 2 nd and the 6th day, P > 0.05; On day 4, the CM/Tg group was significantly higher than that of CM/WT group, P < 0.01; the results of CMs derived from PMs were consistent with the above trend. The expression of α-SMA mRNA on the 2nd, 4th and 6th day was detected by real-time Q-PCR method using BM-derived CMs. No significant difference was found between the groups on the 2nd day (P > 0.05).α-SMA mRNA increased further on the 4th and 6th day, and the level of CM/Tg in CM/Tg group was significantly higher than that in CM/WT group (P < 0.05). The detection results of CMs derived from PMs were consistent with the above trend. The results of CCK-8 assay and BrdU assay showed that the proliferation rate of HSCs in CM Tg group was significantly higher than that in CM/WT group (P < 0.01). The CMs derived from PMs were used to interfere with HSCs. And the results were consistent with the above trend. For BMMs, the levels of IL-1β and PDGF-BB in the lipopolysaccharide (LPS) + IFNγ/Tg culture supernatant were significantly higher than those in the LPS+IFNγ/WT group (P < 0.01). For the culture supernatants of PMs Liquid test results consistent with the above trend. Conclusion Macrophages with high expression of TL1A could enhance the activation and proliferation of HSCs by increasing the secretion of IL-1β and PDGF-BB.

Objective To investigate the predictive value of interleukin-33(IL-33),eosinophil chemotactic factor(Eotaxin),soluble scavenger receptor CD163(sCD163)for recurrent wheezing in children with bronchi-olitis.Methods A total of 120 children with bronchiolitis who were treated in Jiamusi Maternal and Child Health Hospital from August 2019 to October 2021 were enrolled in the study.The clinical data of the chil-dren were collected,including demographic factors,birth factors,atopic factors,length of hospital stay,time from symptom onset to visit,and respiratory distress assessment tool(RDAI)score.Respiratory syncytial vi-rus(RSV)and rhinovirus(RV)were detected.Blood samples were collected for detection.Blood test indica-tors included total immunoglobulin E(IgE),white blood cell count(WBC),IL-33,Eotaxin and sCD163.The discharged children were followed up for 1 year,and they were divided into non-recurrent group and recurrent group according to the number of wheezing episodes.The two groups were compared in terms of clinical data and blood test indicators.Logistic regression was used to analyze the risk factors for recurrent wheezing in children with bronchiolitis.Pearson correlation analysis was used to analyze the correlation between blood test indexes and RDAI score.The receiver operating characteristic(ROC)curve was drawn to analyze the value of IL-33,Eotaxin,and sCD163 levels alone and in combination in predicting recurrent wheezing in children with bronchiolitis.Results Compared with the non-recurrent group,the recurrent group had significantly higher RDAI score,higher proportion of patients with a history of eczema,a personal history of allergy,and a signifi-cantly higher RSV infection rate(P＜0.05).The recurrent group had significantly higher levels of IL-33,Eotaxin,and sCD163 than the non-recurrent group(P＜0.05).Pearson correlation analysis showed that the levels of IL-33,Eotaxin,and sCD163 in children with bronchiolitis were positively correlated with RDAI score(r=0.516,0.611,0.522,P＜0.05).Logistic regression analysis showed that RDAI score,history of eczema,personal history of allergy,RSV infection,increased IL-33 levels,increased Eotaxin levels,and increased sCD163 levels were risk factors for recurrent wheezing in children with bronchiolitis(OR＞1,P＜0.05).The ROC curve found that The area under the curve(AUC)of IL-33,Eotaxin,and sCD163 levels alone and in combination for predicting recurrent wheezing in children with bronchiolitis was 0.829(95％CI:0.757-0.901),0.858(95％CI:0.794-0.922),and 0.857(95％CI:0.789-0.925)and 0.954(95％CI:0.921-0.987).Conclusion Increased levels of IL-33,Eotaxin and sCD163 in children with bronchiolitis can increase the risk of recurrent wheezing,and the combined detection of the three can effectively predict the occurrence of recurrent wheezing.
