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.

OBJECTIVE: To investigate the clinical efficacy of thoracoscopic minimally invasive surgery with nickel-titanium shape memory alloy wrap bone plate versus rib periosteal internal fixation in patients with multiple rib fractures (MRF) and flail chest. METHODS: A retrospective analysis was performed on 100 patients with MRF and flail chest treated with thoracoscopic minimally invasive surgery and internal fixation with rib fracture preservation between January 2019 and December 2022, including 54 males and 46 females, aged from 20 to 65 years old, with an average age of (38.0±18.0)years old. The duration of the disease ranged from 8 to 21 days. According to the different surgical methods, the patients were divided into control group and study group, with 50 patients in each group. The control group consisted of 23 males and 27 females, with an average age of (38.35±18.05) years old, who underwent rib preservation periosteal internal fixation. In the study group, there were 31 males and 19 females, with an average age of (38.15±17.99) years old, treated with thoracoscopic nickel-titanium shape memory alloy circumferential bone plate. The pulmonary function indices, electrocardiographic monitoring indices, pain severity, levels of inflammatory factors, complications, rehabilitation indices, and therapeutic efficacy were compared between the two groups before and after treatment. RESULTS: All patients were followed up for 6 months. After 3 days of treatment, the heart rate of both groups was (102.43±13.74) beats per minute vs (86.26±8.06) beats per minute, respiratory rate (28.45±3.40) breaths per minute vs (22.05±2.85) breaths per minute, blood oxygen saturation (89.68±3.66)% vs (98.46±4.84)%, rest pain (3.5±0.5) points vs (2.6±0.6) points, movement pain (3.6±0.5) points vs (2.5±0.5) points, and these differences were statistically significant(P<0.05). The levels of Interleukin-6 (IL-6) (102.30±17.00) pg·ml^-1 vs (85.68±21.20) pg·ml^-1 and tumor necrosis factor-alpha (TNF-α)(33.44±4.85) pg·ml^-1 vs (18.14±4.28) pg·ml^-1 in both groups exhibited an increase post-treatment, while the C-reactive protein (CRP) (75.51±10.54) mg·L^-1 vs (60.75±9.84) mg·L^-1 demonstrated a decrease compared to pre-treatment levels. Furthermore, the study group displayed significantly lower levels than the control group (P<0.05). After 10 days of treatment, the peak expiratory flow rate (3.31±0.52) L·s^-1 vs (5.69±0.74) L·s^-1, forced expiratory volume (1.46±0.29) L vs (2.06±0.38) L, and forced vital capacity (2.68±0.95) L vs (4.26±1.05) L of both groups exhibited significant improvements compared to pre-treatment levels. Moreover, the study group demonstrated significantly higher values than the control group (P<0.05). The incidence of postoperative complications in the study group was significantly lower compared to the control group (6 cases vs 14 cases, P<0.05). Additionally, the duration of bone callus formation(9.50±1.40) days and fracture healing (72.20±8.32) days in the study group was significantly shorter compared to the control group(11.35±2.15) days, (93.70±9.90) days (P<0.001). CONCLUSION Compared with traditional rib-preserving internal fixation, patients with MRF and flail chest treated with minimally invasive internal fixation with thoracoscopic nickel-titanium shape memory alloy surround bone plate have better therapeutic effect, because of less surgical trauma, less pain and inflammatory reaction, fewer postoperative pulmonary complications, faster and better recovery of lung function, and thus promote the recovery of patients.

Objective:To investigate the clinical outcomes of using autologous mandibular outer cortex "sandwich" grafting to augment mandible for correcting lower facial asymmetry with normal occlusal relationships.Methods:A retrospective analysis was conducted on the clinical data of patients with lower facial asymmetry treated at the Department of Plastic Surgery, the Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University, from January 2016 to December 2019. Preoperative cone-beam CT (CBCT) scans of the maxillofacial region were obtained to acquire three-dimensional data of the maxillofacial skeleton. Computer-aided design was used to determine the osteotomy range of the mandibular outer cortex and design osteotomy guide template. The outer cortex of the larger mandibular side (donor site) was harvested according to the osteotomy guide template and sectioned. The segmented mandibular outer cortex was then contoured to match the arc of the recipient side’s mandibular outer cortex and fixed to the inner side of the recipient mandibular outer cortex, thus increasing the width and thickness of the expanded mandible. Follow-up was conducted at 7th day and 6 months postoperatively, CBCT scan was performed to measure the changes in ramus height (Co-Go), mandibular body length (Go-Me), and mandibular outer cortex thickness, and volume, and the patient satisfaction with facial appearance (1 to 5 points, with higher scores indicating higher satisfaction), were assessed to evaluate surgical outcomes. Statistical analysis was performed using SPSS 12.0 software. Paired t-tests were used to compare patient satisfaction scores preoperatively and six months postoperatively. Repeated measurement ANOVA was used to compare Co-Go and Go-Me measurements preoperatively, 7th day, and 6 months postoperatively. If a statistically significant difference is found, further analysis using post-hoc testing(Tukey’s HSD test) will be conducted to examine the data. Results:Sixteen patients with lower facial asymmetry were included, comprising of 5 males and 11 females, aged 18 to 40 years, with an average age of 25.2 years. Surgical method included contralateral mandibular outer cortex "sandwich" grafting to the expanded mandible in 9 cases and simultaneous genioplasty in 7 cases. Follow-up ranged from 6 months to 5 years, with an average follow-up of 18.6 months. All patients experienced numbness of the lower lip postoperatively, which resolved within six months, and no severe complications occurred. The symmetry of lower facial contour improved significantly and remained stable. Patient satisfaction score for facial appearance increased from (1.63±0.62) points preoperatively to (4.19±0.75) points six months postoperatively( P<0.01). The differences in Co-Go on the donor side and Go-Me on the recipient side across the three time points(preoperatively, 7th day and 6 months postoperatively) were not statistically significant(all P>0.05). However, the differences in Go-Me on the donor side and Co-Go on the recipient side across the three time points were statistically significant(all P<0.05). On the donor side, the mandibular outer cortex thickness decreased by a maximum of 6 mm on 7th day postoperatively and increased by a maximum of 2 mm at 6 months postoperatively compared to 7th day. On the recipient side, mandibular outer cortex thickness increased by a maximum of 6 mm on 7th day postoperatively and decreased by a maximum of 2 mm at six months postoperatively compared to 7th day. The volume of the mandibular outer cortex on the recipient side increased by (4 415.94±1 017.21)mm 3 at 7th day postoperatively compared to preoperatively, and decreased by (202.63±300.85)mm 3 at 6 months postoperatively. Conclusion:For lower facial asymmetrical with normal occlusal relationships and no occlusal plane deviation, contralateral mandibular outer cortex "sandwich" bone grafting can effectively increase the width and volume of the mandible on the grafted side, achieving favorable clinical outcomes.

The concept of'harmony'is the soul of traditional Chinese culture,which has a profound impact on the formation and development of traditional Chinese medicine(TCM).TCM is rooted in traditional Chinese culture,and the mode of thinking in TCM is in line with traditional Chinese culture.Based on the harmony culture,TCM has developed a unique view of health,disease and therapeutics.From the view of the harmony culture and by combining with years of clinical experience in treating dermatosis,Chinese medical master XUAN Guo-Wei has applied the concept of'harmony'in the TCM syndrome differentiation and treatment system in clinic,and has developed the academic thoughts of harmonizing therapy for removing toxins for the diagnosis and treatment of dermatosis.The thoughts of harmonizing therapy for removing toxins includes four aspects,namely harmonizing yin and yang,harmonizing healthy qi and pathogenic qi,harmonizing water and fire(i.e.,clod and hot),and harmonizing the administration of formula and drugs,aiming to remove toxins and expel pathogens and value the harmony.The thoughts of harmonizing therapy for removing toxins will beneficial to the comprehensive understanding of the unique health-disease-therapeutics concept in TCM,and will be helpful for managing the doctor-patient relationship,which is of enlightening significance to the modern clinical practice with TCM.

Objective To elucidate the molecular genetic etiology of patients with disorders of sex development(DSD)using whole exome sequencing(WES),thereby enhancing our understanding of the underlying mechanisms of sexual development abnormalities.Methods Retrospective analysis was conducted on clinical data of 60 DSD patients diagnosed in the First People's Hospital of Yunnan Province between March 2008 and August 2021,with an additional family study for one proband.Genomic DNA was extracted from patients for WES analysis.Single nucleotide polymorphism(SNP)and insertions/deletion(InDel)tests were identified using SAMtools software in conjunction with established SNP and InDel databases.Copy number variations(CNVs)at the exon level were detected using ExomeDepth,while the potential pathogenicity of mutations was predicted with PolyPhen-2,Mutation taster and PyMol software,with Sanger sequencing employed for confirmation.Results The study included 22 patients with 46,XX DSD and 38 with 46,XY DSD.Among the 46,XX DSD patients,the SRY gene was detected in 14 patients.In the remaining 8 patients and a proband's families,single nucleotide site variations(SNVs)of NR5A1,PROKR2 and ANOS1 genes were identified in 2 patients,and CNVs in CYP21A2 gene were found in 4 patients.The pathogenicity of CYP21A2 EX1 Dup has been previously reported,while the remaining 3 CNVs were of uncertain significance,and no DSD-related mutations were detected in 2 patients.In the WES analysis of 46,XY DSD patients,10 pathogenic or likely pathogenic SNVs across 5 genes(SRY,AR,SRD5A2,CYP17A1,and NR5A1)were identified in 14 patients.Additionally,5 likely pathogenic CNVs involving the CYP21A2,AKR1C2,CBX2,and NR5A1 genes were detected in 5 patients,comprising 3 deletions and 2 duplications.Novel SNVs in NR5A1(c.722G>T,c.48C>G)and ANOS1 c.564A>T were identified,with no prior reports in relevant databases.The pathogenicity of CYP21A2 EX1 Dup is documented in related databases,while the remaining CNVs have not been previously reported.Conclusion The utilization of WES technology has enhanced the diagnostic potential for DSD,broadened the spectrum of known DSD-related gene mutations,and deepened our comprehension of DSD pathogenesis,offering valuable support for genetic counseling.

Objective:To evaluate the efficacy of acute T-cell lymphoblastic leukemia(T-ALL)in children and explore the prognostic risk factors.Methods:The clinical data of 127 newly diagnosed children with T-ALL admitted to five hospitals in Fujian province from April 2011 to December 2020 were retrospectively analyzed,and compared with children with newly diagnosed acute precursor B-cell lymphoblastic leukemia(B-ALL)in the same period.Kaplan-Meier analysis was used to evaluate the overall survival(OS)and event-free survival(EFS),and COX proportional hazard regression model was used to evaluate the prognostic factors.Among 116 children with T-ALL who received standard treatment,78 cases received the Chinese Childhood Leukemia Collaborative Group(CCLG)-ALL 2008 protocol(CCLG-ALL 2008 group),and 38 cases received the China Childhood Cancer Collaborative Group(CCCG)-ALL 2015 protocol(CCCG-ALL 2015 group).The efficacy and serious adverse event(SAE)incidence of the two groups were compared.Results:Proportion of male,age ≥ 10 years old,white blood cell count(WBC)≥ 50 × 109/L,central nervous system leukemia,minimal residual disease(MRD)≥ 1％during induction therapy,and MRD ≥ 0.01％at the end of induction in T-ALL children were significantly higher than those in B-ALL children(P＜0.05).The expected 10-year EFS and OS of T-ALL were 59.7％and 66.0％,respectively,which were significantly lower than those of B-ALL(P＜0.001).COX analysis showed that WBC ≥ 100 x 109/L at initial diagnosis and failure to achieve complete remission(CR)after induction were independent risk factors for poor prognosis.Compared with CCLG-ALL 2008 group,CCCG-ALL 2015 group had lower incidence of infection-related SAE(15.8％vs 34.6％,P=0.042),but higher EFS and OS(73.9％vs 57.2％,PEFS=0.090;86.5％vs 62.3％,PoS=0.023).Conclusions:The prognosis of children with T-ALL is worse than children with B-ALL.WBC ≥ 100 × 109/L at initial diagnosis and non-CR after induction(especially mediastinal mass has not disappeared)are the risk factors for poor prognosis.CCCG-ALL 2015 regimen may reduce infection-related SAE and improve efficacy.
