Nuclear factor-kappa B （NF-κB） is an important intracellular transcription factor widely involved in the processes such as immune response， inflammatory response， cell proliferation， and apoptosis. The abnormal activation of the NF-κB signaling pathway plays a pivotal role in various liver diseases including chronic hepatitis， liver fibrosis， liver cirrhosis， and hepatocellular carcinoma. Extensive studies have shown that inhibiting NF-κB activity may effectively reduce inflammation and fibrosis and improve metabolic disorders. Several natural compounds， such as matrine and salvianolic acid B， have shown the potential in suppressing NF-κB activity， thereby exerting anti-inflammatory， anti-fibrotic， and anti-tumor effects. This article systematically reviews the critical role of the NF-κB signaling pathway in liver diseases and its potential as a therapeutic target， in order to highlight its potential as a therapeutic target for liver diseases and provide new directions for the treatment of liver diseases.

Calcium-activated chloride channels(CaCCs)are a class of channel proteins that trans-port chloride ions activated by intracellular calcium,which play a crucial role in regulating membrane potential,intracellular calcium balance,and cell excitability,particularly in neurons and muscle cells.In the Anoctamin(Ano)family,Ano1 is the most classic CaCC.Targeted modulators of Ano1 have poten-tial therapeutic effects against such diseases as cancer,cystic fibrosis,hypertension,diarrhea,and asthma.Since the discovery of Ano1 in 2008,several methods for screening CaCC-specific modulators have emerged including high-throughput primary screening of fluorescent proteins,electrophysiological patch clamp technique and virtual screening,and identification of small molecule modulators with diverse pharmacological effects.This paper summarizes the principles,advantages and disadvantages of the mainstream screening methods,and reviews the chemical structures and potential applications of Ano1-specific modulators discovered to date.

Objective To explore the clinical effect of endoscopic sclerosing agent injection combined with ligation in the treatment of third degree internal hemorrhoids.Methods 100 patients with internal hemorrhoids from January 2019 to August 2022 were prospectively selected and divided into control group(50 patients,treated with ligation)and study group(50 patients,treated with endoscopic sclerosing agent injection combined with ligation).Clinical data of patients were collected,and the clinical efficacy,postoperative recovery related indicators,resting anal pressure,anal canal maximum systolic pressure(AMSP),degree of hemorrhoid prolapse and the incidence of postoperative complications were compared between the two groups.Results The total effective rate of the study group was higher than that of the control group,and the difference was statistically significant(P<0.05);After surgery,the pain score,wound bleeding score,degree of hemorrhoid prolapse score,and anal edema score in the study group were lower than those in the control group,and the differences were statistically significant(P<0.05).After operation,the resting anal pressure and AMSP in both groups were obviously reduced,and the study group was lower than the control group(P<0.05).Conclusion The combination of endoscopic sclerosing agent injection combined with ligation for the treatment of internal hemorrhoids has a significant effect,which can improve the recovery of surgical and postoperative related indicators,improve the anal and intestinal dynamics,reduce the score of hemorrhoid prolapse,and have good safety.

Objective:To analyze the immune reconstitution after BTKi treatment in patients with chronic lymphocytic leukemia(CLL).Methods:The clinical and laboratorial data of 59 CLL patients admitted from January 2017 to March 2022 in Fujian Medical University Union Hospital were collected and analyzed retrospectively.Results:The median age of 59 CLL patients was 60.5(36-78).After one year of BTKi treatment,the CLL clones(CD5+/CD19+)of 51 cases(86.4％)were significantly reduced,in which the number of cloned-B cells decreased significantly from(46±6.1)× 109/L to(2.3±0.4)× 109/L(P=0.0013).But there was no significant change in the number of non-cloned B cells(CD19+minus CD5+/CD19+).After BTKi treatment,IgA increased significantly from(0.75±0.09)g/L to(1.31±0.1)g/L(P＜0.001),while IgG and IgM decreased from(8.1±0.2)g/L and(0.52±0.6)g/L to(7.1±0.1)g/L and(0.47±0.1)g/L,respectively(P＜0.001,P=0.002).BTKi treatment resulted in a significant change in T cell subpopulation of CLL patients,which manifested as both a decrease in total number of T cells from(2.1±0.1)× 109/L to(1.6±0.4)× 109/L and NK/T cells from(0.11±0.1)× 109/L to(0.07±0.01)× 109/L(P=0.042,P=0.038),both an increase in number of CD4+cells from(0.15±6.1)× 109/L to(0.19±0.4)× 109/L and CD8+cells from(0.27±0.01)× 109/L to(0.41±0.08)× 109/L(both P＜0.001).BTKi treatment also up-regulated the expression of interleukin(IL)-2 while down-regulated IL-4 and interferon(IFN)-γ.However,the expression of IL-6,IL-10,and tumor necrosis factor(TNF)-α did not change significantly.BTKi treatment could also restored the diversity of TCR and BCR in CLL patients,especially obviously in those patients with complete remission(CR)than those with partial remission(PR).Before and after BTKi treatment,Shannon index of TCR in patients with CR was 0.02±0.008 and 0.14±0.001(P＜0.001),while in patients with PR was 0.01±0.03 and 0.05±0.02(P＞0.05),respectively.Shannon index of BCR in patients with CR was 0.19±0.003 and 0.33±0.15(P＜0.001),while in patients with PR was 0.15±0.009 and 0.23±0.18(P＜0.05),respectively.Conclusions:BTKi treatment can shrink the clone size in CLL patients,promote the expression of IgA,increase the number of functional T cells,and regulate the secretion of cytokines such as IL-2,IL-4,and IFN-γ.BTKi also promote the recovery of diversity of TCR and BCR.BTKi treatment contributes to the reconstitution of immune function in CLL patients.

Objective To explore and implement a differentiated management strategy for multi-campus hospitals to improve patient experience and satisfaction,and achieve the goal of homogenized management.Methods In December 2021,the Picker Patient Experience Questionnaire was used to survey the patient experience at 3 campuses of a tertiary A hospital in Hangzhou,and the reasons for the differences were analyzed.Based on policy document reviews,special group discussions,and expert meetings,differentiated management strategy for multi-campus hospitals was formulated.The patient experience and satisfaction before(December 2021)and after(December 2023)the implementation were compared.Results After the application of the one-hospital multi-campus difference management strategy,the overall medical experience score of the patients in the 3 campus was(58.54±2.36)points,which was higher than(58.13±3.24)points before the application(t=-3.223,P=0.001),and there was no statistically significant differences among the patients in the 3 campuses(F=0.781,P=0.458).After the application of the management strategy,the overall satisfaction score of the patients in the 3 campus was(98.44±6.22)points,which was higher than(97.98±6.87)points before the application of the management strategy(t=-2.490,P=0.013),and there was no statistical significance among the patients in the 3 campus(F=1.128,P=0.324).The number of banners and letters of commendation received by the 3 campuses increased from 1 661 before the application to 2 190 after the application,with a growth rate of 31.85％.Conclusion Differentiated management in a multi-campus hospital,aiming at homogenized quality through differentiated strategies,is practicable and can significantly improve the patient experience and satisfaction across different campuses.

Objective:To identify the risk factors for delayed gastric emptying in patients scheduled for elective caesarean section.Methods:One hundred and five patients, aged≥18 yr, at≥37 week gestation, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective caesarean section from August 2023 to February 2024, who followed the preoperative fasting guidelines, were collected. Based on the quantitative and qualitative ultrasound assessments of the gastric antrum, patients were divided into 2 groups: delayed gastric emptying group, as defined by Perlas A score of grade 2 or the presence of solid contents or gastric volume/weight >1.5 ml/kg, and non-delayed gastric emptying group, as defined by Perlas A score < grade 2 and gastric volume/weight ≤1.5 ml/kg. The variables of which showed statistically significant differences in the intergroup comparison would enter the logistic regression analysis to stratify the risk factors for delayed gastric emptying before elective caesarean section.Results:There were 41 parturients (39.0%) showed delayed gastric emptying before elective caesarean section. According to the results of multifactorial logistic regression analysis, the gastroesophageal reflux disease( OR=5.313, 95% confidence interval 1.013-27.878, P=0.048) was an independent risk factor for delayed gastric emptying in the patients who underwent elective caesarean section. Conclusions:Gastroesophageal reflux disease is an independent risk factor for delayed gastric emptying in the patients scheduled for elective caesarean section.

Objective:To explore the effect of dietary modification-assisted multimodal therapy in the prevention and treatment of chronic prostatitis.Methods:A total of 132 cases of chronic prostatitis treated in the Outpatient Department of our hospital were randomly divided into an observation group(n=68)and a control group(n=64),the former following the Mediterranean dietary pattern,the latter adhering to their own dietary habits,and meanwhile both receiving lifestyle guidance,psychological counseling,symptomatic medication and physiotherapy according to their specific symptoms.The patients were followed up for 4 weeks,therapeutic effects were observed and comparisons were made between the two groups in the NIH-CPSI scores before and after treatment.Re-sults:Compared with the baseline,the quality of life(QOL)scores,pain and urination discomfort scores and total NIH-CPSI scores were significantly decreased in both the observation and the control groups after treatment(P<0.05),even more decreased in the former than in the latter,but with no statistically significant difference between the two(P>0.05).The rate of therapeutic effective-ness was higher in the observation group than in the control(87.1%vs 79.7%,but showed no statistically significant difference be-tween the two groups(P>0.05).Conclusion:Multimodal therapy is suitable for the management of different clinical manifesta-tions of individual patients,while dietary habits vary from person to person as well as from region to region.Therefore,scientific dietary modification for the prevention and treatment of CP/CPPS needs further exploration.

Objective:To investigate the selection of the modality of transperineal surgery and its effect in the treatment of pel-vic fracture-induced posterior urethral atresia(PUA).Methods:This study included 116 cases of PUA caused by pelvic fractures treated in our hospital from January 2012 to December 2021.We used transperineal resection of the urethral stricture and end-to-end u-rethral anastomosis(EEUA)as the first choice in the treatment of 79 cases.For the patients with the urethral atresia segment longer than 3 cm and evident urethral involution tension,we incised the penile septum,separated and removed the muscle tendon and scar tis-sue attached to the lower border of the pubis,and anastomosed with 4-0 absorbable thread for 8 stitches.For the other 37 cases for which we were not sure of effective suture of the membrane due to obvious scarring of the proximal urethra,the remaining urethra shor-ter than 5 mm or incomplete urethral mucosa,we selected conventional urethral pull-through operation(UPTO).We followed up the patients for 3-24 months postoperatively.Results:The total success rate of surgery was 78.4％(91/116),81.1％(30/37)in the UPTO and 77.2％(61/79)in the EEUA group,significantly higher in the former than in the latter(P=0.05).The rate of post-operative dysuria was remarkably lower in the UPTO than in the EEUA group(13.5％[5/37]vs 16.5％[13/79],P=0.05),and so was that of surgical failure(5.4％[2/37]vs 6.3％[5/79],P=0.05).The main causes of postoperative dysuria in the EEUA group included restenosis resulting from incomplete scar resection and the two sides of the anastomosed urethral segment not being at the coaxial level,while those in the UPTO group included the formation of mucosal flaps in the pulled-through urethra,and re-scarring leading to stricture or the pulled-through urethra not being at the coaxial level.Among the 7 cases of surgical failure due to recurrence,1 refused reoperation and opted for cystostomy tube drainage,and the other 6 underwent EEUA again 6 months later.Conclusion:EEUA is preferred as the first-choice surgery for PUA,while UPTO remains an effective treatment option in hospitals with preliminary skills and less experience in the management of PUA.

A 79-year male presenting with abdominal distension, diarrhea, edema and oliguria, which soon progressed to acute renal failure, was admitted in Xiamen Branch of Zhongshan Hospital. The diagnosis of atypical hemolytic uremic syndrome (aHUS) was confirmed after admission. The hematological parameters and renal function were improved after prompt hemodialysis, plasma exchange, plasma and immunoglobulin transfusion. The patient experienced multiple recurrences of aHUS within 1 year, but achieved long-term remission with regular use of eculizumab. The reported cases of aHUS were searched from Wanfang Data Knowledge Service Platform and CNKI Database from January 2000 to January 2024, and 64 non-pregnant adult aHUS cases were retrieved from literature. The analysis of 65 cases showed a male-to-female ratio was 1.2∶1 and an average age of 34.8 years ranging from 20 to 86 years. Common clinical manifestations included fever (24 cases, 36.9%), renal dysfunction (27 cases, 41.5%), and neurological symptoms (15 cases, 23.1%). Additionally, 40 cases (61.5%)had concomitant hypertension. Among the 65 patients, 36 (55.4%) received hemodialysis, 31 (47.7%) underwent plasma exchange or plasma transfusion, 29 (44.6%) were treated with glucocorticoids, and only 3 (4.6%) were treated with eculizumab. In terms of treatment outcomes, 29.2% (19 cases)of the patients achieved complete renal function recovery, 46.2% (30 cases)developed end-stage renal disease, and 4 patients died. aHUS presents with a variety of clinical manifestations involving multiple systems. Plasma exchange remains the primary treatment method at present. Early and accurate diagnosis, prompt and effective treatment can significantly improve patient prognosis.
