Oral anti-viral agents nucleos (t)ide analogues (NAs) are widely used in treatment of chronic hepatitis B (CHB) since they are well-tolerated in most patients.But clinical relapse occurs in a considerable part of patients after the cessation of NAs therapy.This paper reviews factors related to clinical relapse, including time for drug withdrawal, cccDNA level, age, baseline alanine aminotransferase (ALT) and HBV DNA levels, type of NAs, serum level of HBsAg and the immune status of patients.

Objective To research the relationship between hypertensive disorder complicating pregnancy and serum free estriol 3 (FE3) and explore its impact on pregnancy outcome.Methods Clinical data of 117 hypertensive disorder complicating pregnancy and 165 normal pregnant women were retrospectivly analyzed.Chemiluminescence immunoassay determination of maternal serum FE3 also had been conducted.Then analyzing the correlation between hypertensive disorder complicating pregnancy and FE3 and its impact on pregnancy outcomes.Results LDL cholesterol and the level of creatinine of observation group were significantly lower than the control group(t =3.129,9.372,all P ＜ 0.05),while blood pressure,triglycerides,HDL,and 24-hour urinary protein content were significantly higher than control groug(t =7.361,2.398,2.833,all P ＜ 0.05).The FE3 level of the observation group were significantly lower than the control group (t =2.913,P ＜ 0.05).There was a significant positive correlation between the FE3 level of normal pregnant women and their gestational age (r =0.937,P ＜ 0.05).The probabilities of premature birth,premature rupture of membranes,postpartum hemorrhage,and neonatal asphyxia of observation group were significantly higher than amtrol group (x2 =3.912,3.879,4.267,6.935,all P ＜ 0.05).Conclusion There is a significant correlation between hypertensive disorder complicating pregnancy and FE3,which has an important significance on monitoring the health status of pregnant women and the fetal-placental function.

ObjectiveTo observe the effect of early rehabilitation on motor function, high-sensitivity C-reactive protein (hs-CRP), interleukin-1（IL-1） and interleukin-6（IL-6） in patients with acute cerebral infarction (ACI). Methods160 patients with ACI were randomly divided into rehabilitation group (n=80) and control group (n=80), who accepted early rehabilitation and routine medicine or medicine only, respectively. They were assessed with modified Edinburgh-Scandinavian Stroke Scale (MESSS) and their peripheral level of hs-CRP, IL-1 and IL-6 were detected before and 1, 2, 4, and 8 weeks after treatment. Results4 and 8 weeks after treatment, the level of hs-CRP, IL-1 and IL-6 were lower in rehabilitation group than in control group（P＜0.05）, as well as the scores of the MESSS （P＜0.01）. The incidence of improvement is more in rehabilitation group than in control group（P＜0.05）. ConclusionEarly rehabilitation can reduce the expression of hs-CRP, IL-1 and IL-6, and improve the neurological function in patients with ACI.

Objective:To investigate the expression of serum matrix metalloproteinase 3 (MMP-3) in patients with rheumatoid arthritis (RA) and analyze its correlation with bone erosion and disease activity.Methods:100 RA patients diagnosed in the First People's Hospital of Changde from July 2018 to December 2019 were selected as the RA group, and 35 healthy volunteers who came to the hospital for physical examination at the same time were selected as the control group. The clinical data of the patients were collected, and the serum MMP-3 levels of the patients and healthy volunteers were detected by enzyme-linked immunosorbent assay (ELISA). The serum MMP3 levels of RA patients with different disease activity, different imaging stages and different bone mineral density were compared, and the correlation with clinical indicators were analyzed.Results:⑴ RA patients were grouped according to the Disease Activity Score (DAS) 28. Serum MMP-3 levels in the highly active group (300.87±15.93)ng/ml and in the moderately active group (213.78±12.79)ng/ml were higher than those in the clinical remission group (82.87±8.19)ng/ml increased significantly. ⑵ The serum MMP3 level in the RA group (190.98±13.43)ng/ml was significantly higher than that in the healthy control group (69.97±10.63)ng/ml. ⑶ There were significant differences in serum MMP-3 levels among RA patients with different imaging stages ( P<0.05). The level of MMP-3 in stage Ⅲ (206.18±13.58)ng/ml and stage Ⅳ (301.72±13.43)ng/ml were significantly higher than those in stage Ⅰ (89.16±10.13)ng/ml. ⑷ RA patients were divided into normal group, osteopenia group, and osteoporosis group according to bone mineral density. The serum MMP-3 level in the osteopenia group (180.87±12.69)ng/ml and osteoporosis group (289.54±13.28)ng/ml were significantly higher than that in the normal group (121.05±8.45)ng/ml. ⑸ Serum MMP-3 levels were positively correlated with C-reaction (CRP), erythrocyte sedimentation rate (ESR), DSA 28, rheumatoid factor (RF), joint swelling index, joint tenderness index, and platelet count in the RA group ( P<0.05). Conclusions:The serum MMP-3 plays an important role in the progression of RA, and is closely related to RA disease activity and bone erosion. It is expected to become a serological indicator for predicting RA bone erosion and radiological progress.

Objective To observe the clinical application of surgical lateral position and its influence on the postoperative recovery efficacy in patients with posterior laparoscopic operation in Department of Urological Surgery.Methods A total of 100 patients with surgical lateral position in posterior laparoscopic operation in Department of Urological Surgery were randomly divided into ob-servation group and control group,50 cases for each.Modified surgical lateral position was given to observation group in which adjustable plates were put on the involved upper limbs and orifice plates were fixed on sacrococcygeal and scapular regions respectively,with self-made rectangular neony-chiums (80 cm×25 cm×20 cm)being placed under involved lower limbs,while traditional one to control group in which un-adjustable plates were performed.Satisfactory degrees of physicians and patients as well as postoperative complication rate were observed in both groups.Results Observa-tion group was apparently higher in satisfactory degrees of physicians and patients but were marked-ly lower in the total rate of complications than control group,and the differences were all significant (P <0.01).Conclusion Modified surgical lateral position in posterior laparoscopic operation can improve the satisfactory degree s of physicians and patients,decrease the total rate of complications and promote surgical nursing quality,which deserves to be widely used in clinic.

Objective To analyze the distribution features of newly reported cases of occupational welder′s pneumoconiosis (OWP) in Guangdong Province from 2013 to 2022. Methods Data of newly reported cases of OWP from National Occupational Disease Network Direct Reporting System of Guangdong Province from 2013 to 2022 was analyzed using conventional data analyzing Methods. Results A total of 294 cases of OWP were reported in Guangdong Province from 2013 to 2022 with an overall downward trend. The average age at diagnosis for new OWP cases was 44±6 years old, and the median of dust exposure duration was 11 years. Males accounted for 99.3% of the cases, and 94.2% of the cases were phase Ⅰ OWP. Guangzhou City had the highest regional distribution with 74.8% of the cases. The industry distribution was mainly manufacturing, accounting for 86.7% of the cases. The scale of enterprises was most common in small enterprises, followed by large and medium-sized enterprises, accounting for 38.4%, 30.6% and 24.5% of the cases respectively. The economic types of enterprises were mostly private enterprises, followed by state-owned enterprises, accounting for 54.1% and 32.0% of the cases respectively. Conclusion In Guangdong Province, the newly reported OWP cases were clustered in terms of disease stage, regional distribution, industry, enterprise scale and enterprise economic type. There was a tendency of younger age at diagnosis and shorter dust exposure duration.

Objective To study the correlation between interleukin(IL)-21 and the recurrence of chronic hepatitis B(CHB)in hepatitis B e antigen(HBeAg)-positive patients after discontinuation of entecavir(ETV).Methods A total of 112 HBeAg-positive CHB patients treated with ETV were enrolled.Serum levels of IL-21 at week 0,12,24 and 52 after ETV discontinuation were detected.The Cox regression model was used to analyze the correlation between IL-21 and the recurrence after ETV discontinuation.The receiver operating characteristic(ROC)curve was applied to determine the predictive value of IL-21 for CHB recurrence after ETV discontinuation.The expression differences of IL-21 were compared between sustained viral response(SVR)group and viral relapse(VR)group.The t test and Chi-square test were used for statistical analysis.Results The serum levels of IL-21 in SVR group at week 0,12,24 and 52 after ETV withdrawal were(60.0 ± 10.8),(60.2 ± 14.7),(60.6 ± 19.5)and (61.2 ± 15.4)ng/L,respectively,which were all significantly higher than those in VR group(47.5 ± 10.7),(47.3 ± 12.9),(46.9 ± 12.2)and(46.4 ± 12.8)ng/L,respectively(t=6.153,4.926,4.382 and 5.515,respectively,all P< 0.01).The area under curve(AUC)was 0.811(95% CI:0.728 ~0.893,P<0.01)and the best cut-off value of serum IL-21 level was 49.8 ng/L.The recurrence rates of patients with serum IL-21 level ≥49.8 ng/L and <49.8 ng/L at time of ETV withdrawal was 25.4%(16/63)and 77.6%(38/49),respectively.The difference was statistically significant(χ2=30.027,P<0.01).The serum IL-21 level at the time of drug withdrawal(P= 0.005),serum hepatitis B surface antigen(HBsAg)level at the time of HBeAg seroconversion(P= 0.008)and age(P= 0.016)were factors associated with CHB recurrence after ETV withdrawal by multivariate Cox model analysis.The serum levels of ALT,HBV DNA,HBeAg and HBsAg in SVR group were significantly lower than those of VR group at week 12,24 and 52 after ETV withdrawal(t= -5.968,-7.691,-8.093; -3.047,-9.477,-28.900;-2.872,-10.424,-18.330;-4.633,-4.030 and -5.032,respectively;all P<0.01).Serum level of IL-21 was negatively correlated with HBsAg in SVR group after ETV withdrawal (r= -0.241,P<0.01),while positively correlated with HBsAg in VR group(r=0.286,P<0.01). Conclusions The serum IL-21 level at the time of drug withdrawal is associated with the recurrence after ETV discontinuation.IL-2l may play an important role as an immunomodulatory factor in maintaining virological responses in HBeAg-positive CHB patients after ETV withdrawal.

Actinomycosis is a rare chronic granulomatous disease characterized by granuloma formation and tissue fibrosis with sinus tracts,often misdiagnosed due to its similarity to many infectious and non-infectious diseases.This report presents a case of a 60-year-old female with more than 10 years history of rheumatoid arthritis who developed actinomycosis infection after long-term treatment with immunosuppressants and biologics,including methotrexate,leflunomide,and infliximab,leading to recurrent joint pain,poorly controlled rheumatoid arthritis activity,and persistent elevation of white blood cell counts.Abdominal CT revealed a pelvic mass and right ureteral dilation.Pathological examination of cervical tissue showed significant neutrophil infiltration and sulfur granules,indicating actinomycosis.The patient received 18 months of doxycycline treatment for the infection and continued rheumatoid arthritis therapy with leflunomide,hydroxychloroquine sulfate,and tofacitinib,resulting in improved joint symptoms and normalized white blood cell counts.After 2 years of follow-up,the patient remained stable with no recurrence.This case highlights the importance of clinicians being vigilant for infections,particularly chronic,occult infections from rare pathogens,in rheumatoid arthritis patients on potent immunosuppressants and biologics,advocating for early screening and diagnosis.
