Objective:To analyze the liver histological characteristics and clinically related factors in inactive hepatitis B surface antigen (HBsAg) carriers (IHC), and also explore whether antiviral treatment is necessary for IHC, as defined in the 2022 version of the hepatitis B prevention and treatment guidelines.Methods:A multicenter, retrospective cohort study was conducted. Two hundred and thirty-one IHC cases who underwent liver biopsy histopathological examination in nine medical institutions, including Beijing Youan Hospital affiliated with Capital Medical University, from January 2018 to December 2023 were included. General informative data, clinical serological markers, and transient elastography (TE) examination results were collected. Patients were divided into a positive (148 cases) and a negative group (83 cases) according to the results of hepatitis B virus (HBV) DNA detection. The differences in liver pathological inflammatory activity (G) and liver fibrosis stage (S) were analyzed between the two groups to explore the correlation between liver tissue conditions and clinically related factors. Comparsions of normally distributed continwous data, skeukd continuous data, and categorical data between groups are performed using t tests, Mann-Whitney U tests and χ2 tests, respectively. Results:The age of 231 IHC cases was 43 (38, 51) years old, with 95.2% (220/231) aged ≥30 years, and males accounted for 64.9% (150/231). HBsAg and HBV DNA levels were 131.9 (20.8, 400.9) IU/mL and 94.0 (0, 448.5) IU/mL, respectively, of which 35.9% (83/231) were HBV DNA negative (<20 IU/mL). The remarkable proportions of G≥2, S≥2, and liver injury (G≥2 and/or S≥2) in liver tissue were 16.5% (38/231), 29% (67/231), and 35.9% (83/231), respectively. The S≥2 proportion was significantly higher in the HBV DNA-negative group than the positive group (42.2% vs. 21.6%, P<0.001), and it mainly occurred in the population cohort over 30 years old (44.9% vs. 31.0%, P=0.04). The liver stiffness measurement (LSM), aspartate transaminase to platelet ratio index (APRI), and platelet (PLT) were significantly higher in the S≥2 group than the S<2 group ( P<0.05). Conclusion:Clinicians can comprehensively evaluate the degree of liver fibrosis in IHC based on clinical factors such as age, PLT, APRI, and LSM, even if the liver histological results are lacking. The China 2022 version guidelines define that nearly half of IHC has histological indications for antiviral therapy, and liver biopsy and prompt treatment can be recommended.

Objective To evaluate the effect of berberine on the expression of cell cycle-related miRNA and its target gene in human melanoma A375 cells.Methods In vitro cultured A375 cells were classified into several groups to be treated with berberine at different concentrations of 0 (blank control group),20,40,60,80,and 100 μmol/L,respectively,for 48 hours.qRT-PCR was performed to determine the mRNA expression of miRNA-582-5p and its target gene cyclin-dependent kinase 1 (CDK1),miRNA-188-5p and its target gene CDK2,Cyclin D1 and Cyclin A.Western blot analysis was conducted to measure the protein expression of cell cycle-related proteins CDK1,CDK2,Cyclin D1 and Cyclin A.Results qRT-PCR showed that compared with the blank control group,the 20 and 40 μmol/L berberine groups had a similar expression of miRNA-582-5p (both P ＞ 0.05),but the 60 and 80 μmol/L berberine groups had a significantly up-regulated expression of miRNA-582-5p (both P ＜ 0.05).Compared with the blank control group,all the 5 berberine groups had a significantly increased expression of miRNA-188-5p (F =22.600,P =0.002).However,the mRNA expression of CDK2,CDK1,Cyclin A and Cyclin D1 gradually decreased along with the increase of berberine concentrations (F =51.976,248.510,626.671 and 312.740,respectively,all P ＜ 0.001).Western blot analysis revealed that berberine decreased the protein expression of CDK1,CDK2,Cyclin D1 and Cyclin A (F =138.124,110.966,278.772 and 140.167,all P ＜ 0.001).Conclusion Berberine can decrease the expression of cell cycle-related proteins CDK1,CDK2,Cyclin D1 and Cyclin A,likely by decreasing their mRNA expression and increasing the expression of miRNA-582-5p and miRNA-188-5p,and then block the cell cycle progression of A375 cells and inhibit the growth of tumor.

Objective To investigate the effect of a fast-track based clinical nursing pathway of hepatic carcinoma on patient satisfaction and job satisfaction of nurses. Methods A total of 91 primary hepatic carcinoma (PHC) patients undergoing elective hepatectomy were enrolled and were divided into two groups by admission time, namely the control group (48 cases) and the experimental group (43 cases). The patients in the control group received traditional perioperative nursing care of hepatectomy, while the cases in the experimental group participated in fast-track nursing pathway. Patient satisfaction and nurse job satisfaction were measured before and after implementation. Results Final analysis included 45 patients in the control group and 40 patients in the experimental group. In the experimental group, the total score of patient satisfaction and the scores of all dimensions (including services and techniques, concern and care, services and techniques and overall satisfaction) were (132.75 ± 13.71), (48.30 ± 6.53), (42.60 ± 4.62), (35.98 ± 3.85), (5.88 ± 0.94), while they were (122.89 ± 16.62), (44.53 ± 7.74), (39.49 ± 5.67), (33.53±4.40), (5.33±1.13) in the control group. And the scores of the experimental group were significantly higher than that of the control group (t=-2.961, t=-2.409, t=-2.753, t=-2.709, t=-2.389, P<0.05). Furthermore,after implementing the fast-track clinical nursing pathway,the total score of nurse job satisfaction and the scores of six factors were (143.23 ± 9.40), (28.45 ± 2.72), (24.82 ± 2.28), (23.05 ± 1.33), (13.91 ± 1.95), (15.05 ± 1.43), (16.64 ± 1.65) while they were (127.36 ± 13.14), (25.68 ± 4.16), (19.64 ± 2.75), (20.23 ± 2.35), (13.23 ± 2.22), (13.68 ± 2.01), (14.50 ± 1.95) before the implementation. The former was significantly better than the latter (t =-12.462,-7.743,-12.670,-6.560,-2.417,-1.483,-6.587,P<0.05). However, no differences were observed in the other two dimensions of wages and benefits andwork-family balance(t =-1.945,-1.312,P>0.05) since the scores after implementation were (13.86 ± 2.12), (7.45 ± 1.57), while that of (13.18 ± 2.30)、(7.23 ± 1.41) were obtained before performance. Conclusions Application of fast- track nursing pathway in perioperative patients with PHC can contribute to promoting the level of patient satisfaction and job satisfaction of nurses and improving nursing quality. It is suggested that this nursing pathway will have more potential value for PHC patients.

More than 94% of hospitals established CSSD management system and regulations,>90% of hospitals met the requirements of CSSD layout;All hospitals were equipped with pressure steam sterilizer,all levels of hospitals basically equipped with the necessary equipments and facilities;CSSD respon-sible officers of 94.52% (345/365)of hospitals participated in training on standards;69.61% (252/362)of hospi-tals were using or developing CSSD information systems;>92% of the CSSD responsible officers considered that three standards played an important role in facilitating centralized management,and improving the quality of clean-ing,disinfection and sterilization.Conclusion Hospitals need to strengthen the management and training on stand-ards of CSSD,management of loaner instruments and development of information system need to be standardized.

ObjectiveTo evaluate the effect of health education to women of childbearing age on knowledge of birthdefents.MethodsRandomly selected 200 case of maternal pre-pregnancy check-up in the hospital outpatient department were divided into two groups,The observation group of 100 cases,100 cases of the control group.the control group received rule progestation knowledge education,the observation group enforce health education intervention,apply the way of questionnaire survey,and the results were statistically analyzed.ResultsThe observation group answer correct rate is obviously higher than the control group ( all P ＜ 0.05 ).ConclusionTaking a variety of measures of health education for pregnant women during the physical examination for effective interventions,could significantly improve the population birth defects knowledge rate had positive significance to the prevention of birth defects.

Objective To study the effects of angiotensin Ⅱ (AngⅡ) on insulin signal transduction pathway in skeletal myoblast of L6 rats,and further to explore the possible mechanism of AngⅡ on glucose utilization.Methods Myoblast cells of L6 rats were cultured and induced to differentiate.They were divided into 4 groups according to different treatment by AngⅡ or JAK2-PKA inhibitor H89:normal control group ( NC group),insulin group,insulin + AngⅡ group and insulin + AngⅡ + H89 group.Expression of IRS1 and GLUT4 mRNA was detected by RT-PCR.Expression of IRS1,Ptyr-IRS1 and GLUT4 (total and membrane protein) were detected by Western blot.Results The difference of GLUT4 mRNA expression in the 4 groups detected by RT-PCR had no statistical significance(P ＞ 0.05).The difference of IRS1 mRNA expression among the latter 3 groups had no statistical significance(P ＞ 0.05),however,IRS1 expression in the latter 3 groups was higher than that in NC group(P ＜ 0.05).Western blot results showed expression of IRS1,Ptyr-IRS1 and GLUT4 (membrane protein)was higher in the latter 3 groups than in NC group(P ＜0.05).The difference of IRS1 expression among the latter 3 groups(P ＞ 0.05 ) and GLUT4 (total protein) expression among the 4 groups had no statistical significance (P ＞ 0.05).The expression of of ptyr-IRS1 and GLUT4 membrane protein in Ins + AngⅡ + H89 group was much higher than that in Ins + AngⅡ group,and lower than that in insulin group(P ＜0.05).Conclusion AngⅡ inhibits IRS1's tyrosine phosphorylation and GLUT4's transfer from cytoplasm to plasma membrane in skeletal muscle cells through JAK2-PKA signaling pathway,and therefore induces insulin resistance.

OBJECTIVETo detect the expression of cytokines by acute promyelocytic leukemia (APL) cells before and after exposure to arsenic trioxide.

METHODSDiagnoses were performed according to the FAB cytological classification criteria and cytogenetic criteria. Bone marrow or blood samples from APL patients were collected in heparinized tubes, then primary APL cells were separated by traditional Ficoll-Hypaque density centrifugation and purified after adherence to plastic surfaces. IL-1(beta), IL-6, IL-8, TNF alpha and G-CSF levels in the leukemia cell culture supernatants were detected by ELISA. At the same time, nitro blue tetrazolium (NBT) reduction test was used to detect the differentiation of APL cells.

RESULTSAfter 96 hours exposure to arsenic trioxide, 10 - 6 mol/L in vitro or 10 mg/d in vivo, APL cells showed a significant increase of IL-1(beta) (P < 0.05) and G-CSF (P < 0.05) production, and a significant decrease of IL-6 (P < 0.05) and IL-8 (P < 0.05). However, there was no obvious variation of TNF alpha when compared with APL cells without exposure to arsenic trioxide. On the other hand, the proliferation ratio of APL cells in vitro was statistically correlated to the IL-1(beta) secretion ratio or G-CSF secretion ratio. The cell number ratio in patients with detectable IL-1(beta) or G-CSF was higher than that without detectable IL-1(beta) or G-CSF.

CONCLUSIONIL-1(beta) and G-CSF secretion may play an important role in the proliferation of APL cells after exposure to arsenic trioxide.
