As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

This article presents a case study of a patient who visited the Geriatric Department of Peking Union Medical College Hospital due to "palpitations, shortness of breath for more than 2 years, limb weakness for 6 months, edema, and nocturnal dyspnea for 2 months". The patient exhibited decreased muscle strength in the limbs and involvement of swallowing and respiratory muscles, alongside complications of heart failure and various arrhythmias which were predominantly atrial. Laboratory tests revealed the presence of multiple autoantibodies and notably anti-mitochondrial antibodies. Following a comprehensive multidisciplinary evaluation, the patient was diagnosed with anti-mitochondrial antibody-associated inflammatory myopathy. Treatment involved a combination of glucocorticoids and immunosuppressants, along with resistance exercises for muscle strength and rehabilitation training for lung function, resulting in significant improvement of clinical symptoms. The case underscores the importance of collaborative multidisciplinary approaches in diagnosing and treating rare diseases in elderly patients, where careful consideration of clinical manifestations and subtle abnormal clinical data can lead to effective interventions.

Objective: To systematically evaluate the influencing factors for repeated implantation failure (RIF) after in vitro fertilization-embryo transfer (IVF-ET) in China, so as to provide the evidence for prevention of RIF. Methods: Literature on influencing factors for RIF in China were retrieved from CNKI, Wanfang Data, VIP, China Medical Literature Service System, PubMed, Web of Science, Cochrane Library and Embase from inception to September, 2024. A meta-analysis was performed using RevMan 5.3 and Stata 14.0 softwares. Literature were excluded one by one for sensitivity analysis. Publication bias was evaluated using Egger's test. Results: Initially 4 836 relevant articles were retrieved, and 12 of them were finally included, with a total sample size of 11 554 individuals. There were 10 case-control studies, 1 cohort study, and 1 cross-sectional study; and 10 high-quality studies and 2 medium-quality studies. The meta-analysis showed that factors including advanced age (OR=1.121, 95%CI: 1.035-1.215), prolonged infertility duration (OR=1.237, 95%CI: 1.091-1.403), abnormal hysteroscopy findings (OR=2.205, 95%CI: 1.119-4.348), positive anti-nuclear antibody (ANA) (OR=2.393, 95%CI: 1.473-3.886), and positive anti-beta2 glycoprotein Ⅰ antibody (β2-GPⅠ-Ab) (OR=2.824, 95%CI: 1.987-4.013) were associated with an increased risk of RIF; while factors including the large number of embryos transferred (OR=0.309, 95%CI: 0.098-0.973), thicker endometrium (OR=0.601, 95%CI: 0.556-0.650), and higher granulocyte colony-stimulating factor (G-CSF) levels (OR=0.657, 95%CI: 0.511-0.845) were associated with a reduced risk of RIF. Conclusion IVF-ET RIF is associated with age, infertility duration, number of embryos transferred, endometrial thickness, hysteroscopy findings, G-CSF levels, ANA and β2-GPⅠ-Ab.

Objective To investigate the incidence of neglected perforation of sterile surgical gloves used in craniocerebral surgery and its effect on bacterial contamination of the gloves.Methods A total of 996 sterile surgical gloves worn by surgical participants during craniocerebral surgery were selected as the study objects.Univariate and multivariate Logistic regression analysis were respectively performed to analyze the factors that might cause the neglected perforation of gloves,and the detection rate of bacteria on the outer surface of perforated and unperforated gloves were compared.Results Among 996 sterile surgical gloves used in craniocerebral surgery,84(8.43%)gloves were found to have neglected perforation,and 39(3.92%)gloves were found to have bacteria.The detection rate of bacteria on the outer surface of the neglected perforation group was significantly higher than that of the non-neglected perforation group(P<0.001).The results of univariate and multivariate Logistic analysis suggested that craniotomy,emergency surgery,surgery time≥150 minutes,the use of rotating equipment during surgery and the role of glove wearing personnel as the main surgeon were the risk factors for neglected perforation of sterile surgical gloves(OR>1,P<0.05),while the use of double-layer gloves during surgery was the protective factor for avoiding perforation(OR<1,P<0.05).Conclusion The occurrence of neglected perforation of sterile surgical gloves during craniocerebral surgery is not optimistic.The probability of neglected perforation of gloves is higher in craniotomy,emergency surgery,long surgery time,the use of rotating equipment during surgery,and gloves used by the main surgeon.For surgeries with a high incidence of neglected perforation,double-layer gloves can be worn during surgery to reduce bacterial contamination on the outer surface of sterile surgical gloves.

AIM:To explore the molecular mecha-nism of Fuyangjing gel in the treatment of chronic eczema rats model based on janus protein kinase 1(JAK1)/signal transducer and activator of transcrip-tion 5(STAT5)signaling pathway.METHODS:Thirty-six SPF Wistar rats were randomly divided into nor-mal group,model group,Qingpeng ointment group,Fuyangjing gel low,medium and high dose groups.Except the normal group,the other groups of rats were treated with 2,4-dinitrochlorophenone solution to induce chronic eczema-like lesions on the back.After 3 weeks of modeling,Qingpeng ointment group and Fuyangjing gel low,medium and high dose groups were respectively treated with corresponding drugs.The model group was smeared with blank gel matrix once a day for 2 weeks,while the normal group was not treated.The severity and pathological changes of back le-sions in chronic eczema rats were observed.The ex-pression of phosphorylated protein tyrosine kinase 1(p-JAK1)and phosphorylated signal transduction and transcriptional activator 5(p-STAT5)in rat dor-sal skin was detected by Western blot.Detection of thymic stromallymphopietin(TSLP),JAK1,STAT5,in-terleukin-10(IL-10)and IL-17 mRNA expression lev-els in rat back skin by qRT-PCR;The levels of IL-4,IL-6,IL-10,IL-13 and IL-17 in serum of rats were deter-mined by enzyme-linked immunosorbent assay(ELI-SA).RESULTS:Compared with normal group,the se-rum levels of IL-4,IL-6,IL-13 and IL-17 in model group were significantly increased,while IL-10 lev-els were significantly decreased(P＜0.05).The ex-pression levels of p-JAK1,p-STAT5 protein and TSLP,JAK1,STAT5 and IL-17 mRNA in back lesions were significantly increased,while IL-10 mRNA levels were significantly decreased(P＜0.05).Compared with model group,serum levels of IL-4,IL-6,IL-13 and IL-17 in Qingpeng ointment group and Fuy-angjing gel low,medium and high dose groups were significantly decreased,while IL-10 levels were significantly increased(P＜0.05).The expres-sion levels of p-JAK1,p-STAT5 protein and TSLP,JAK1,STAT5 and IL-17 mRNA in back lesions were significantly decreased,while the mRNA levels of IL-10 were significantly increased(P＜0.05).The serum levels of IL-4,IL-6,IL-13 and IL-17 in Qingpeng oint-ment group were decreased,while IL-10 levels were increased(P＜0.05).The expression levels of p-JAK1,p-STAT5 protein and TSLP,JAK1,STAT5 and IL-17 mRNA in back lesions were decreased,while the mRNA levels of IL-10 were increased(P＜0.05).Com-pared with Qingpeng ointment group,there were no significant differences in serum levels of IL-4,IL-6,IL-10,IL-13 and IL-17 in Fuyangjing gel high-dose group(P＞0.05).There were no significant differenc-es in the expression levels of p-JAK1,p-STAT5 pro-tein and TSLP,JAK1,STAT5,IL-10 and IL-17 mRNA in back lesions(P＞0.05).CONCLUSION:Fuyangjing gel may play a role in the treatment of chronic eczema by regulating the expression of JAK1/STAT5 signal-ing pathway related inflammatory factors,proteins and genes.

Objective:To explore the characteristics of brain dynamic activity in patients with schizophrenia by using functional magnetic resonance imaging(fMRI).Methods:Forty-three patients with schizophrenia and 31 normal controls were recruited and under fMRI scanning.The Positive and Negative Symptom Scale(PANS)was used to assess the severity of clinical symptoms.The DPABI software were used to compute dReHo and dFC.Granger causality analysis was used to calculate the effective connectivity between the significant brain regions of dReHo and the whole brain.Two sample t-test was performed to compare the difference of dReHo and dFC be-tween patients with schizophrenia and normal controls.Results:The dReHo of left postcentral gyrus(LPG)(P＜0.01,cluster-level FWE corrected)in patients with schizophrenia was decreased.The Dfc was increased between left postcentral and left middle frontal gyrus,left superior medial frontal gyrus,right calcarine,left medial cingulum gyrus,right supplementary motor area(P＜0.01,uncorrected).Compared with normal controls,patients with schiz-ophrenia showed decreased effective connectivity from LPG to right putamen.Conclusion:It suggests that the ab-normal functional activity of the postcentral gyrus mightcontribute to the neural physiopathology in patients with schizophrenia.

Objective:To explore the clinical effects of free anterolateral thigh perforator flap (ALTPF) with modified cross-leg vessel bridging in reconstruction of infected wounds in the lower leg combined with major vessel defects.Methods:A retrospective observational study was conducted on 7 patients who admitted to the Department of Trauma Orthopaedics, the 521 Hospital of Norinco Group from January 2020 to December 2021 for treatment of large infected wounds in lower leg with soft tissue defect by reconstructive surgery of flap transfer. The patients were 5 males and 2 females, aged 23-50 years old with an average age of 37 years old. The causes of injury were: 5 patients were of car accidents, 1 of machinery compression and 1 of heavy object crush. The wounds were reconstructed after debridement and infection control with sensitive antibiotics, where the soft tissue defects were found at 11.0 cm×15.0 cm to 20.0 cm×32.0 cm in size. All patients underwent vascular angiography or CDU examinations and it was confirmed that the affected calf had only an anterior tibial artery as the vessel left for blood supply in 6 patients and a posterior tibial artery as the blood supply vessel in one patient. Therefore application of vascular end-to-side anastomosis in free flap reconstruction of limb defects was impossible due to the damaged artery could not be salvaged as a blood supply artery for the transferred flap. Therefore, a modified cross-leg vessel bridging to the freed ALTPF in the affected lower leg was applied. The donor site of the pedicle was covered with VSD while the pedicle of the flap was anastomosed. It was remained until the posterior tibial artery and the tubular flap were ready for replantation after disconnection of the pedicle. The sizes of flap were 13.0 cm×17.0 cm to 22.0 cm×32.0 cm (unilateral ALTPFs for 6 patients and bilateral ALTPFs for 1 patient). Two donor sites in low tension were direct closed, and the rest of 5 donor sites that had great tensions and could not be directly sutured were reconstructed by skin grafting. The survival and complications of flaps were observed in the scheduled postoperative follow-ups at outpatient visits, WeChat reviews and home visits, etc.Results:All 7 patients were successfully treated and had 12-24 months postoperative follow-up, with an average of 16 months. All flaps survived, with primary healing in 6 patients and 1 patient had partial flap necrosis with surface infection, which healed after dressing changes. The wound healing time was 14-36 days with an average of 17.9 days. The time for disconnection of the cross-leg vessel bridging pedicle was 3-4 weeks with the flap transfer, with an average of 3.6 weeks. The donor sites of ALTPFs and vessel pedicles all healed well. CDU confirmed the patency of the contralateral posterior tibial artery. Satisfactory functional recovery was achieved in the affected lower limb and there was a good function of the contralateral healthy lower leg.Conclusion:Application of the transfer of a free ALTPF with modified cross-leg vessel bridging in reconstruction of infected wounds with major vessel defects in the lower leg has shown excellent clinical outcomes. It is a practical and effective method in treatment of large infective defect in lower leg.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and highly aggressive hematological malignancy, there is no standard treatment and the prognosis is very poor. Affiliated Zhongshan Hospital of Dalian University report a case of 85-year-old BPDCN male patient treated with DVT regimen (decitabine combined with Venetoclax and thalidomide) and achieved complete remission. The patient with skin nodules and the pathology diagnosed BPDCN, the next generation sequencing of skin nodules showed mutations of IDH2 and ASXL1. DVT (decitabine combined with Venetoclax and thalidomide) has significant efficacy with rapid and deep remission for BPDCN, and the adverse effects is less, especially suitable for elderly patients who cannot tolerate intense chemotherapy.
