ObjectiveTo explore the changes in color， odor and chemical components during wine-processing of Chuanxiong Rhizoma（CR）， identify differential markers， and provide a basis for standardizing the process and establishing quality standards. MethodsFifteen batches of CR samples from 4 producing areas were collected. Colorimeter and electronic nose were used to detect the color changes and odor components of CR before and after wine-processing. Multivariate statistical methods including partial least squares-discriminant analysis（PLS-DA）， principal component analysis（PCA）， discriminant factor analysis（DFA） and Fisher discriminant analysis were applied to identify wine-processed CR at different processing stages and establish discriminant models， and differential components were screened out based on variable importance in the projection（VIP） value1. Then， high performance liquid chromatography（HPLC） was employed to detect the content changes of four components（ferulic acid， senkyunolide I， senkyunolide A and ligustilide） during the processing stages. ResultsThe differences of wine-processed CR at various stages were primarily reflected in color parameters L^*（brightness value）， a^*（red-green value） and b^*（yellow-blue value）. Based on chromaticity differences， the color reference ranges were established for moderately processed CR， including L^* of 46.75-48.24， a^* of 5.37-6.07 and b^* of 20.32-21.70. In odor analysis， DFA revealed significant differences among processing stages， and 11 odor markers were identified， with four differential markers（4-hydroxy-3-butylphthalide， isopropyl butyrate， L-limonene and 1-methoxyhexane） based on VIP values. HPLC results showed that there was no significant difference of the four components except for ligustilide in wine-processed CR at different stages. ConclusionThis study achieved rapid identification of wine-processed CR with different processing degrees by electronic sensory technology and differential component content detection， with discrimination accuracy rates of 92.4% and 93.272% for color and odor， respectively. This paper also established the reference ranges of main colorimetric parameters for wine-processed CR at different stages， and four differential components were screened out， providing a basis for standardizing the processing of wine-processed CR and establishing quality standards for this decoction pieces.

ObjectiveTo investigate the clinical features and outcomes of recompensation in patients with autoimmune hepatitis （AIH）-related decompensated cirrhosis， to identify independent predictive factors， and to construct a nomogram prediction model for the probability of recompensation. MethodsA retrospective cohort study was conducted among the adult patients with AIH-related decompensated cirrhosis who were admitted to The Fifth Medical Center of PLA General Hospital from January 2015 to August 2023 （n=211）. The primary endpoint was achievement of recompensation， and the secondary endpoint was liver-related death or liver transplantation. According to the outcome of the patients at the end of the follow-up， the patients were divided into the recompensation group （n=16） and the persistent decompensation group（n=150）.The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data with heterogeneity of variance； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups； the Kaplan-Meier method was used for survival analysis； the Cox proportional-hazards regression model was used to identify independent predictive factors， and a nomogram model was constructed and validated. ResultsA total of 211 patients were enrolled， with a median age of 55.0 years and a median follow-up time of 44.0 months， and female patients accounted for 87.2%. Among the 211 patients， 61 （with a cumulative proportion of 35.5%） achieved recompensation. Compared with the persistent decompensation group， the recompensation group had significantly higher white blood cell count， platelet count （PLT）， total bilirubin （TBil）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， total bile acid， prothrombin time， international normalized ratio （INR）， SMA positive rate， Model for End-Stage Liver Disease （MELD） score， Child-Pugh score， and rate of use of glucocorticoids （all P0.05）， as well as significantly lower age at baseline， number of complications， and death/liver transplantation rate （all P0.05）. At 3 and 12 months after treatment， the recompensation group had continuous improvements in AST， TBil， INR， IgG， MELD score， and Child-Pugh score， which were significantly lower than the values in the persistent decompensation group （all P0.05）， alongside with continuous increases in PLT and albumin， which were significantly higher than the values in the persistent decompensation group （P0.05）. The multivariate Cox regression analysis showed that baseline ALT （hazard ratio ［HR］=1.067， 95% confidence interval ［CI］： 1.010 — 1.127， P=0.021）， IgG （HR=0.463，95%CI：0.258 — 0.833， P=0.010）， SMA positivity （HR=3.122，95%CI：1.768 — 5.515， P0.001）， and glucocorticoid therapy （HR=20.651，95%CI：8.744 — 48.770， P0.001） were independent predictive factors for recompensation， and the nomogram model based on these predictive factors showed excellent predictive performance （C-index=0.87，95%CI：0.84 — 0.90）. ConclusionAchieving recompensation significantly improves clinical outcomes in patients with AIH-related decompensated cirrhosis. Baseline SMA positivity， a high level of ALT， a low level of IgG， and corticosteroid therapy are independent predictive factors for recompensation. The predictive model constructed based on these factors can provide a basis for decision-making in individualized clinical management.

BACKGROUND: Lung cancer is currently the most prevalent malignancy and the leading cause of cancer deaths worldwide. Although the early stage non-small cell lung cancer (NSCLC) presents a relatively good prognosis, a considerable number of lung cancer cases are still detected and diagnosed at locally advanced or late stages. Surgical treatment combined with perioperative multimodality treatment is the mainstay of treatment for locally advanced NSCLC and has been shown to improve patient survival. Following the standard methods of neoadjuvant therapy, perioperative management, postoperative adjuvant therapy, and other therapeutic strategies are important for improving patients' prognosis and quality of life. However, controversies remain over the perioperative management of NSCLC and presently consensus and standardized guidelines are lacking for addressing critical clinical issues in multimodality treatment. METHODS: The working group consisted of 125 multidisciplinary experts from thoracic surgery, medical oncology, radiotherapy, epidemiology, and psychology. This guideline was developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The clinical questions were collected and selected based on preliminary open-ended questionnaires and subsequent discussions during the Guideline Working Group meetings. PubMed, Web of Science, Cochrane Library, Scopus, and China National Knowledge Infrastructure (CNKI) were searched for available evidence. The GRADE system was used to evaluate the quality of evidence and grade the strengths of recommendations. Finally, the recommendations were developed through a structured consensus-building process. RESULTS: The Guideline Development Group initially collected a total of 62 important clinical questions. After a series of consensus-building conferences, 24 clinical questions were identified and corresponding recommendations were ultimately developed, focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assement, and follow-up protocols for NSCLC. CONCLUSIONS This guideline puts forward reasonable recommendations focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assessment, and follow-up protocol of NSCLC. It standardizes perioperative multimodality treatment and provides guidance for clinical practice among thoracic surgeons, medical oncologists, and radiotherapists, aiming to reduce postoperative recurrence, improve patient survival, accelerate recovery, and minimize postoperative complications such as atelectasis.

PURPOSE: Postpancreatectomy hemorrhage (PPH) is a life-threatening complication after pancreatoduodenectomy. Stent-graft implantation is an emerging treatment option for PPH. This study reports the outcome of PPH treated with stent-graft implantation. METHODS: This was a single-center, retrospective study. Between April 2020 and December 2023, 1723 pancreatectomy cases were collected while we screened 12 cases of PPH after pancreatoduodenectomy treated with stent-graft implantation. Patients' medical and radiologic images were retrospectively reviewed. Technical and clinical success, complications, and stent-graft patency were evaluated. Continuous data are reported as means ± standard deviation when normally distributed or as median (Q₁, Q₃) when the data is non-normal distributed. Categorical data are reported as n (%). A p < 0.05 was considered statistically significant. Kaplan-Meier estimates were used for stent patency and patients' survival. RESULTS: Pancreatic fistula was identified in 6 cases (50.0%), and pseudoaneurysm was identified in 3 cases (25.0%), including pancreatic fistula together with pseudoaneurysm in 1 case (8.3%). All pseudoaneurysm or contrast extravasation sites were successfully excluded with patent distal perfusion, thus technical success was achieved in all cases. The overall survival rate at 6 months and 1 year was 91.7% and 78.6%, respectively. One patient had herniation of the small intestine into the thoracic cavity, which caused a broad thoracic and abdominal infection and died during hospitalization. Rebleeding occurred at the gastroduodenal artery stump in 1 case after stent-graft implantation for the splenic artery and was successfully treated with another stent-graft implantation. Two cases of asymptomatic stent-graft occlusion were observed at 24.6 and 26.3 after the operation, respectively. CONCLUSIONS With suitable anatomy, covered stent-graft implantation is an effective and safe treatment option for PPH with various bleeding sites and causes.

Objective:To investigate the correlation of serum visfatin and resistin levels with cardiometabolic index (CMI) and bone mineral density (BMD) in elderly patients with essential hypertension (EH) complicated with osteoporosis (OP) .Methods:From Feb. 2021 to Feb. 2023, 120 elderly patients with EH complicated with OP in Department of Cardiovascular Medicine, Hangzhou Hospital of Traditional Chinese Medicine were chosen (the EH complicated with OP group), and 50 healthy physical examination subjects (the NC group) and 50 EH complicated with low bone mass (the EH complicated with low bone mass group) were chosen as the control. Venous blood samples were collected from all patients, serum visfatin and resistin levels were measured, and CMI and BMD were tested. Statistical methods were used to analyze the data.Results:In EH patients with decreased bone mass or OP, the level of serum visfatin was often low, but resistin was elevated, which showed significant differences compared with that in the NC group ( F visfatin = 26.02, F resistin = 9.50, P < 0.001). The CMI in NC group was lower than that in the other two groups ( F = 52.54, P < 0.001). In terms of bone mass, BMD in NC group was higher than that in the other two groups, especially in the key parts of lumbar spine ( F=21.44, P < 0.001), femoral neck ( F=10.54, P < 0.001), Chinese triangle ( F=12.30, P < 0.001) and femoral trochanter ( F=4.87, P < 0.001), etc. BMD in EH complicated with low bone mass was also higher than that in EH complicated with OP group, including lumbar spine ( t=4.60, P < 0.001), femoral neck ( t=2.32, P=0.022), Chinese triangle ( t=4.58, P < 0.001) and femoral trochoid ( t=4.33, P < 0.001). In addition, visfatin was positively correlated with bone mass ( P < 0.05), lumbar spine ( r=0.36, P < 0.001), femoral neck ( r=0.38, P < 0.001), Chinese triangle ( r=0.28, P=0.020) and femoral trochoid ( r=0.37, P < 0.001), while resistin was negatively correlated with bone mass, lumbar spine ( r=-0.40, P < 0.001), femoral neck ( r=-0.50, P < 0.001), and femoral trochanter ( r=-0.40, P < 0.001). However, there was no significant correlation between CMI and visfatin ( r=0.06, P > 0.05) and resistin ( r=0.11, P > 0.05). Logistic analysis showed that visfatin level was a risk factor of OP in EH patients ( P < 0.001), and resistin was a protective factor ( P = 0.008) . Conclusion:Serum visfatin and resistin levels in elderly EH patients complicated with OP are correlated with BMD, suggesting that they may play an important role in disease development and treatment.

Objective:To establish ultra performance liquid chromatography (UPLC) characteristic chromatogram of Pulsatilla chinensis; To provide reference for the origin identification and quality control of Pulsatilla chinensis. Methods:UPLC Method was adopted. The determination was performed on a column of Agilent SB C18 (2.1 mm×100 mm, 1.8 μm) . The mobile phase was acetonitrile-methanol (2:1) -0.1% phosphoric acid solution by fradient elution at a flow rate of 0.30ml/min. The column temperature was 30 ℃. The detection wavelength was 215 nm. The injection volume was 2 μl. The common counterfeit products and medicinal herbs of Pulsatilla chinensis from different areas were evaluated by comparison of characteristic chromatogram, principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). Results:There were 9 characteristic peaks in the characteristic chromatogram of Pulsatilla chinensis, and 8 common peaks were identified by high resolution mass spectrometry and comparison of reference materials. Through PCA analysis, it was possible to clearly distinguish the medicinal herbs of Pulsatilla chinensis from different areas. Combined with OPLS-DA analysis, it was found that peak 2, peak 3, peak 6 were the main markers of Pulsatilla chinensis from different producing areas. Conclusion:The established method has good specificity, repeatability and durability, and it can effectively distinguish the common counterfeits of Pulsatilla chinensis, and provide the basis of quality control and selection of origin for Pulsatilla chinensis.

Objective:To analyze the incidence and progression of overactive bladder(OAB)symp-toms following radical prostatectomy for prostate cancer patients and to identify related risk factors.Methods:A retrospective study was conducted on 263 local stage prostate cancer patients who underwent radical prostatectomy at Peking University Third Hospital from January 2013 to May 2017.Clinical base-line information,comprehensive imaging features,perioperative parameters,preoperative urinary control status,pathological diagnosis,and the incidence of OAB within one year postoperatively were collected and analyzed.In the imaging features,two parameters were defined:Bladder wall thickness(BWT)and bladder mucosal smoothness(BMS),which were used to predict the occurrence of OAB.Patients were evaluated based on their clinical baseline characteristics,including age,body mass index(BMI),co-morbidities,and prostate-specific antigen(PSA)levels.The imaging characteristics were assessed using preoperative MRI,focusing on BWT and BMS.Perioperative parameters included operative time,blood loss,and length of hospital stay.The OAB symptoms were assessed using the overactive bladder symptom score(OABSS)and the international prostate symptom score(IPSS).These scores were correlated with the postoperative incidence of OAB.Results:Among the 263 patients who underwent radical prostatecto-my,52(19.8％)exhibited OAB within one year postoperatively.Of the 40 patients with preoperative OAB symptoms,17(42.5％)showed remission postoperatively,while 23(57.5％)had persistent symptoms.Additionally,29 patients developed new-onset OAB,accounting for 55.77％of all postopera-tive OAB cases.Univariate analysis indicated that BWT,BMS,OABSS,and IPSS score were all associ-ated with the occurrence of postoperative OAB.Further multivariate analysis identified BMS as an inde-pendent risk factor for long-term OAB(P＜0.001).Conclusion:Long-term postoperative overactive bladder is a common complication following radical prostatectomy.The findings suggest that preoperative MRI measurements of bladder wall thickness and bladder mucosal smoothness during bladder filling phase can predict the risk of OAB occurrence postoperatively.Identifying these risk factors preoperatively can help in counseling patients about potential complications and in developing strategies to mitigate the risk of developing OAB after surgery.Early detection and management of these parameters might improve the quality of life for patients undergoing radical prostatectomy.

Objective:To explore the technical focus of robotic-assisted laparoscopic surgery for the treatment of horseshoe kidney combined with renal tumor.Methods:The clinical data of a patient with horseshoe kidney combined with renal tumor treated by robot-assisted laparoscopic partial nephrectomy in the Second Hospital of Dalian Medical University in September 2021 were retrospectively analyzed. PubMed, CNKI, Wanfang and VIP databases were searched for all the literature on the use of robot-assisted laparoscopic nephrectomy or partial nephrectomy for the treatment of horseshoe kidney combined with renal tumor from the time of establishment to December 2022.Results:A total of 11 patients from 10 articles were retrieved and 12 patients were enrolled. Among the 12 patients, 4 cases used the retroperitoneal approach and 8 cases used the transperitoneal approach. Two cases were operated by traditional laparoscope, and the arteries were searched for and controlled before the robotic arm was placed to perform the partial nephrectomy and suture; and 10 cases were operated with the robotic-assisted laparoscopic approach throughout the whole procedure. Five cases of nephrectomy were performed on one side, and 7 cases were performed in the partial nephrectomy. Postoperative pathological diagnosis was clear cell carcinoma in 8 cases, chromophobe cell carcinoma in 1 case, eosinophilic cell carcinoma in 1 case, renal cell carcinoma in 1 case, and renal abscess in 1 case. The patient in the Second Hospital of Dalian Medical University was 38 years old female who was admitted to the hospital with a fever. After CT arteriography and three-dimensional reconstruction, robotic-assisted laparoscopic partial nephrectomy of right kidney and isthmus dissecting was performed. During the operation, tumor trophoblast vessels were ligated and dissected one by one by using single-use tissue closure clips, and the isthmus was dissected using endoscopic cutting anastomosis on the left side of the tumor, with the tumor edges sharply resected and completely dissected. The operation time was 240 min, without thermal ischemia time, and the bleeding volume was about 300 ml. The patient recovered well after the operation, and the postoperative pathological diagnosis was renal abscess.Conclusions:Robot-assisted laparoscopic treatment of horseshoe kidney combined with renal tumor is safe and effective, and has more advantages than traditional laparoscopic surgery. Preoperative CT arteriography or three-dimensional reconstruction examination should be applied to fully evaluate the variant vessels. The surgical access and plan should be decided according to the size and location of the tumor. The variant vessels should be properly handled during operation. The use of endoscopic cutting anastomosis to deal with the isthmus can be more conducive to the surgical operation.

Objective:To evaluate the efficacy of individualized removal therapeutic regimen for donor-specific antibodies (DSA) and examine its related influencing factors.Method:From January 2016 to January 2021, 34 recipients of kidney transplant (KT) underwent regular DSA testing and the results were positive. DSA removal therapy based upon rituximab (RTX) plus intravenous immune globulin (IVIG) was offered. Correlation between DSA negative conversion rate and DSA types, time from start of treatment to transplantation, HLA loci targeted by DSA and DSA mean fluorescent intensity (MFI) were analyzed retrospectively. Changes of immunedominant DSA (iDSA) and serum creatinine in individuals with de novo DSA (dnDSA) before and after treatment were also examined.Results:At Month 3 post-treatment, antibodies turned negative in 17/34(50.0%) patients and DSA became negative in 19/34(55.9%) at the last follow-up. Then we identified 78 DSA from all patients. No significant difference existed in negative conversion rate of pfDSA and dnDSA at Month 3 post-treatment [62.9%(39/62) vs 37.5%(6/16)] and at the last follow-up [4.2%(46/62) vs 56.3%(9/16)]( P=0.067, 0.219). For pfDSA, negative conversion rate of pfDSA with different MFIs after 3-month treatment varied significantly [negative conversion rate of weak positive DSA was 78.6%(33/42) and positive and above DSA 30%(6/20), P<0.001]. It was an independent related factor of whether or not pfDSA could turn negative (48.6%, 95% CI: 22.3%-66.8%, P=0.001). At the last follow-up, negative conversion rate of pfDSA differed markedly at different timepoints from start of treatment to transplantation [treated within 30 days post-operation was 79.2%(42/53) and over 30 days post-operation was 44.4%(4/9), P=0.042] and among different DSA MFI [88.1%(37/42) of weakly positive DSA and 45%(9/20) of positive and above DSA, P<0.001] and they were independent related factors for negative conversion of pfDSA (34.8%, 95% CI: 3.2%-61.8%, P=0.008; 43.1%, 95% CI: 18.5%-63.4%, P=0.001). Mean decline rate in iDSA was 66.67% at Month 3 post-treatment and 77.90% at the last follow-up. The difference was statistically significant ( P=0.035). Serum level of creatinine of 9 patients with dnDSA was (110.2±26.9) μmol/L pre-treatment, (178.8±90.5) μmol/L during treatment, (153.9±72.8) μmol/L at Month 3 post-treatment and (213.6±185.8) μmol/L at the last follow-up. Serum creatinine rose during treatment ( t=-2.794, P=0.023), declined at Month 3 post-treatment ( t=3.430, P=0.009) and spiked again at the last follow-up ( P=0.028). Conclusion:After DSA removal therapy based upon RTX plus IVIG, negative conversion rate of pfDSA is correlated with its MFI and time from start of treatment to transplantation. There is no significant rebound in DSA MFI and graft function of dnDSA patients improves immediately after treatment.
