ObjectiveTo evaluate the clinical efficacy and safety of Huaban Jiedu Formulation （化斑解毒方， HJF） in treating psoriasis vulgaris with blood-heat syndrome. MethodsA randomized， double-blind， placebo-controlled study was conducted with 60 patients diagnosed with psoriasis vulgaris of blood-heat syndrome. Patients were randomly assigned to either a treatment group or a control group， with 30 cases in each. The treatment group received HJF granules orally， one dose a day， combined with topical Qingshi Zhiyang Ointment （青石止痒软膏）， while the control group received placebo granules， one dose a day， combined with the same topical ointment. Both groups were topically treated twice daily of 28 days treatment cours. Psoriasis area and severity index （PASI）， visual analogue scale for pruritus （VAS）， traditional Chinese medicine （TCM） syndrome scores， dermatology life quality index （DLQI）， and psoriasis life stress inventory （PLSI） were assessed before treatment and on day 14 and day 28. Response rates for PASI 50 （≥50% reduction） and PASI 75 （≥75% reduction）， as well as overall clinical efficacy， were compared between groups. Serum levels of interleukin-6 （IL-6） and interleukin-17 （IL-17） were measured before and after 28 days of treatment. Adverse reactions during treatment were recorded. ResultsAfter 28 days of treatment， both groups showed significant reductions in PASI total score， lesion area score， erythema， scaling， and infiltration scores， pruritus VAS score， TCM syndrome score， DLQI， PLSI， and serum IL-6 and IL-17 levels （P＜0.05）. Compared to the control group， the treatment group had significantly greater improvements in PASI total score and erythema score， TCM syndrome score， serum IL-6 and IL-17 levels， and PASI 50 response rate after 28 days （P＜0.05）. Between-group comparisons of score differences before and after 28-day treatment revealed that the treatment group showed significantly better improvements in PASI total， lesion area score， erythema score， TCM syndrome score， DLQI， PLSI， and inflammatory markers （P＜0.05 or P＜0.01）. The total effective rate on day 14 and day 28 was 40.00% （12/30） and 83.33% （25/30） in the treatment group， versus 6.90% （2/29） and 41.38% （12/29） in the control group， respectively. The clinical efficacy in the treatment group was significantly superior to that in the control group （P＜0.05）. Mild gastric discomfort occurred in 3 patients in the treatment group and 1 in the control group. ConclusionHJF can effectively improve skin lesions and TCM symptoms relieve pruritus， enhance quality of life， and reduce inflammatory markers IL-6 and IL-17， in patients with blood-heat syndrome of psoriasis vulgaris， with a good safety profile.

Background and Aims:Single-incision laparoscopic cholecystectomy(LC)has become increasingly popular due to its minimal invasiveness and cosmetic advantages,but challenges remain in biliary identification and limited operative space.Indocyanine green(ICG)fluorescence navigation enables real-time visualization of the biliary tract and may enhance surgical safety and efficiency.This study aimed to evaluate the clinical application value of ICG fluorescence navigation in single-incision LC.Methods:A retrospective analysis was conducted on 59 patients with benign gallbladder diseases who underwent elective single-incision LC at Yixing Hospital affiliated to Jiangsu University from January 2023 to December 2024.Patients were divided into a fluorescence group(n=27)and a white-light group(n=32)according to whether ICG fluorescence navigation was applied.The two groups were compared in terms of Calot's triangle dissection time,operative time,intraoperative blood loss,surgeon satisfaction,hospital stay,and postoperative complications.Results:No significant differences were observed in baseline clinical characteristics between the two groups(all P＞0.05).In the fluorescence group,the cystic duct,common hepatic duct,and common bile duct were all successfully visualized.Compared with the white-light group,the fluorescence group had significantly shorter Calot's triangle dissection time[(25.56±3.49)min vs.(38.81±5.59)min],shorter operative time[(44.67±3.06)min vs.(61.31±4.96)min],and less intraoperative blood loss[(13.44±1.70)mL vs.(14.50±2.11)mL](all P＜0.05),with significantly higher surgeon satisfaction(P＜0.05).No intraoperative bile duct injury,conversion to three-port surgery,or postoperative complications occurred in either group.Conclusion:ICG fluorescence navigation can significantly improve biliary identification efficiency in single-incision LC,shorten operative time,reduce blood loss,and enhance surgeon satisfaction,demonstrating promising clinical application prospects.

Objective To explore the diagnostic value of CT imaging of creeping fat(CF)combined with serum optimization indicators for active Crohn's disease(CD).Methods The data from 68 cases underwent small intestine CT examinations(43 cases in the active CD group and 25 cases in the control group)were collected.CF imaging(non-contrast CT value,enhanced ΔCT value,submucosal fat deposition,and extent of intestinal wrapping)and serum optimization indicators[including neutrophil-to-lymphocyte ratio(NLR),C-reactive protein-to-albumin ratio(CAR),platelet-to-lymphocyte ratio(PLR),platelet-to-albumin ratio(PAR),neutrophil percentage-to-albumin ratio(NPAR),systemic immune-inflammation index(SII),lymphocyte-to-monocyte ratio(LMR),and albumin-to-globulin ratio(AGR)]were evaluated.The correlation between these idictors and CD activity were evaluated.Logistic regression and receiver operating characteristic(ROC)curve analysis were used to assess the diagnostic value of individual and combined indicators for active CD.Results Significant differences were observed in CF imaging and serum optimization indicators between the mild to moderate active CD groups and the control group(P<0.05).The area under the curve(AUC)for non-contrast CT value,arterial phase ΔCT value,venous phase ΔCT value,CF score,NLR,CAR,PLR,PAR,NPAR,SII and combined indicators in predicting moderate active CD were 0.914,0.856,0.923,0.703,0.902,0.880,0.858,0.717,0.802,0.875 and 0.972,respectively.Among these,venous phase ΔCT value and SII exhibited the highest sensitivity(100%),while non-contrast CT value and NPAR demonstrated the highest specificity(87.5%).Venous phase ΔCT value and CAR were identified as significant predictors of moderate active CD(P<0.05).Additionally,serum optimization indicators were significantly correlated with CF imaging(P<0.01).Conclusion CF imaging and serum optimization indicators serve as potential non-invasive markers for diagnosing active CD,with higher diagnostic value achieved through combined assessments.Venous phase ΔCT value and CAR are promising predictors for moderate active CD.

Objective:This multicenter retrospective study aimed to analyze the clinicopathological features of duodenal adenocarcinoma (DA) and identify prognostic factors for postoperative survival.Methods:Demographic characteristics, clinicopathological features, treatment outcomes and survival of DA patients undergoing surgical treatment at 18 Chinese medical centers from January 2012 to December 2023 were retrospectively analyzed.Results:Among the 2 056 DA patients included, 46.8% (963) had extra-ampullary DA (EA-DA), and 53.2% (1 093) had peri-ampullary DA (PA-DA). The 1-, 3-, and 5-year overall survival (OS) rates for patients who underwent radical surgery were 93.2%, 71.0%, and 57.2%, respectively. The median overall survival was 76 months, and the median progression-free survival (PFS) was 65 months. No differences in survival were observed between the laparotomy group and minimally invasive surgery (MIS) group either before or after propensity score matching (OS: 76 vs. 75 months before PSM, P=0.986; OS: 75 vs. 75 months after PSM, P=0.602). Furthermore, there were no significant differences between-group in operation time and postoperative complications ( P＞0.05). The MIS group experienced less intraoperative blood loss and shorter hospital stays. The multivariate Cox regression analysis revealed that advanced age ( HR=1.43,95% CI:1.18-1.73), elevated carbohydrate antigen 19-9 levels ( HR=1.24,95% CI:1.02-1.51), perineural invasion ( HR=1.44,95% CI:1.14-1.81), vascular invasion ( HR=1.35,95% CI:1.07-1.71), advanced T stage (T3-4 vs. T1-2: HR=1.86,95% CI:1.49-2.31), regional lymph node metastasis ( HR=1.93,95% CI:1.58-2.36), preoperative biliary drainage ( HR=1.26,95% CI:1.04-1.53), intraoperative blood loss ( HR=1.34,95% CI:1.11-1.62), clinically significant postoperative pancreatic fistulas ( HR=1.53,95% CI:1.12-2.09), and postoperative hemorrhage ( HR=1.62,95% CI:1.14-2.29) were independent risk factors for poor prognosis after surgery (all P＜0.05). Conclusions:Radical surgery is associated with favorable overall survival among DA patients, and no difference in survival is observed between EA-DA and PA-DA patients. MIS is a reliable alternative for DA treatment.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.
