		                        			Hepatohilar cholangiocarcinoma is a common malignant tumor of the biliary system,and radical surgery is one of the important treatment methods.Due to the narrow space at the hi-lum and the high rate of anatomical variation,radical surgery is challenging.By using medical imag-ing technology and 3D reconstruction,surgeons can accurately determine the stage and classifica-tion of hilar cholangiocarcinoma preoperatively.They can assess the tumor's resectability by Ac-cording to the bile duct separation limit points(U point,P point)and anticipate the impact of portal vein,bile duct,and arterial variations on the surgical plan,thereby improving the rate of radical re-section and reducing complication rates.

		                        			Objective:To investigate the distribution and clinical characteristics of pathogenic bacteria following hematopoietic stem cell transplantation (HSCT), as well as to provide a preliminary research foundation for key microbial monitoring, and clinical diagnosis and treatment of infections after HSCT in hematological patients.Methods:We retrospectively analyzed the clinical data of 190 patients who tested positive for microbial testing [G-bacteria blood culture and/or carbapenem-resistant organism (CRO) screening of perianal swabs] at our center from January 2018 to December 2022. Patients were divided into blood culture positive, perianal swab positive, and double positive groups based on the testing results. The three patient groups underwent statistical analysis and comparison.Results:The top four pathogenic bacteria isolated from sixty-three patients with G-bacteria bloodstream infection (BSI) were Escherichia coli (28 strains, 43.75% ), Klebsiella pneumonia (26 strains, 40.63% ), Pseudomonas aeruginosa (3 strains, 4.69% ), and Enterobacter cloacae (3 strains, 4.69% ). The top three pathogenic bacteria isolated from 147 patients with CRO perianal colonization were carbapenem-resistant Klebsiella pneumoniae (58 strains, 32.58% ), carbapenem-resistant Escherichia coli (49 strains, 27.53% ), and carbapenem-resistant Enterobacter cloacae (20 strains, 11.24% ). The 3-year disease-free survival (DFS ) and overall survival (OS) of double positive group patients were significantly lower compared to those in the blood culture and perianal swab positive groups (DFS: 35.6% vs 53.7% vs 68.6%, P=0.001; OS: 44.4% vs 62.4% vs 76.9%, P<0.001), while non-relapse mortality (NRM) was significantly higher (50.0% vs 34.9% vs 10.6%, P<0.001). Failed engraftment of platelets and BSI are independent risk factors for NRM ( P<0.001). Using polymyxin and/or ceftazidime-avibactam for more than 7 days is an independent protective factor for NRM ( P=0.035) . Conclusion:This study suggests that the occurrence of BSI significantly increases the NRM after HSCT in patients with hematological diseases; CRO colonization into the bloodstream has a significant impact on the DFS and OS of HSCT patients.

		                        			As a traditional Chinese herb and functional food, the fruits of Lycium barbarum has been widely used for thousands of years in China. L. barbarum polysaccharides(LBPs) are predominant active components, which have immunomodulatory, antioxidant, hypoglycemic, neuroprotective, anti-tumor, and prebiotic activities. The molecular weight, monosaccharide composition, glycosidic bond, branching degree, protein content, chemical modification, and spatial structure of LBPs are closely related to their biological activity. Based on the previous studies of this research team, this paper systematically combed and integrated the research progress of structure, function, and structure-activity relationship of LBPs. At the same time, some problems restricting the clarification of the structure-activity relationship of LBPs were considered and prospected, hoping to provide references for the high value utilization of LBPs and in-depth exploration of their health value.

		                        			Huoluo Xiaoling Dan is a classical prescription commonly used for blood circulation and pain relief in clinic with obvious effects. To make it directly treat lesion and improve the effect, this research optimized the preparation process of Huoluo Xiaoling gel paste and further evaluated its in vitro transdermal absorption performance, so as to provide a scientific basis for its development and utilization. Using primary viscosity, holding viscosity, and sensory score as evaluation indexes, the matrix amount of gel paste was determined by the single factor test and Box-Behnken response surface method. The ultra-performance liquid chromatography(UPLC) method was established to determine the content of eight active ingredients, including Danshensu, ferulic acid, salvianolic acid B, salvianolic acid A, ligustilide, tanshinone Ⅱ_A, 11-keto-β-boswellic(KBA), and 3-acetyl-11-keto-β-boswellic acid(AKBA). A mo-dified Franz diffusion cell method was used to evaluate and compare the absorption properties of the gel paste without volatile oil and with volatile oil microemulsion. The results showed that the optimal prescription for Huoluo Xiaoling gel paste matrix was NP700(1.35 g), glycerol(7.00 g), micropowder silica gel(1.25 g), sodium carboxymethyl cellulose(0.20 g), tartaric acid(0.06 g), and glyceryl aluminum(0.04 g). The mass fractions of eight active ingredients in the paste were successively 0.48, 0.014, 0.95, 0.39, 0.57, 0.055, 0.35, and 0.97 mg·g~(-1). The results of the in vitro transdermal absorption test showed that the addition of the volatile oil or the volatile oil microemulsion promoted the transdermal absorption of the active ingredients, and the law of drug penetration conformed to the zero equation or the Higuchi equation. The gel paste prepared by the optimal prescription has good appearance and adhesion, with no residue, and has the characteristics of skeletal slow-release preparation, which is easy to reduce the number of administration, la-ying a foundation for the development of new external dosage forms of Huoluo Xiaoling Dan.

		                        			OBJECTIVE:
		                        			To evaluate the implications of the prognostic nutrition index (PNI) in non-metastatic renal cell carcinoma (RCC) patients treated with surgery and to compare it with other hematological biomarkers, including neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and systemic immune inflammation index (SII).
		                        		
		                        			METHODS:
		                        			A cohort of 328 non-metastatic RCC patients who received surgical treatment between 2010 and 2012 at Peking University First Hospital was analyzed retrospectively. Receiver operating characteristic (ROC) curve analysis was used to determine the optimal cutoff values of the hematological biomarkers. The Youden index was maximum for PNI was value of 47.3. So we divided the patients into two groups (PNI≤ 47. 3 and >47. 3) for further analysis. Categorical variables [age, gender, body mass index (BMI), surgery type, histological subtype, necrosis, pathological T stage and tumor grade] were compared using the Chi-square test and Student' s t test. The association of the biomarkers with overall survival (OS) and disease-free survival (DFS) was analyzed using Kaplan-Meier methods with log-rank test, followed by multivariate Cox proportional hazards model.
		                        		
		                        			RESULTS:
		                        			According to the maximum Youden index of ROC curve, the best cut-off value of PNI is 47. 3. Low level of PNI was significantly associated with older age, lower BMI and higher tumor pathological T stage (P < 0.05). Kaplan-Meier univariate analysis showed that lower PNI was significantly correlated with poor OS and DFS (P < 0.05). In addition, older age, lower BMI, tumor necrosis, higher tumor pathological T stage and Fuhrman grade were significantly correlated with poor OS (P < 0.05). Cox multivariate analysis showed that among the four hematological indexes, only PNI was an independent factor significantly associated with OS, whether as a continuous variable (HR=0.9, 95%CI=0.828-0.978, P=0.013) or a classified variable (HR=2.397, 95%CI=1.061-5.418, P=0.036).
		                        		
		                        			CONCLUSION
		                        			Low PNI was a significant predictor for advanced pathological T stage, decreased OS, or DFS in non-metastatic RCC patients treated with surgery. In addition, PNI was superior to the other hematological biomar-kers as a useful tool for predicting prognosis of RCC in our study. It should be externally validated in future research before the PNI can be used widely as a predictor of RCC patients undergoing nephrectomy.

		                        			Objective:To explore the clinical efficacy of double traction-assisted reduction internal fixation and open reduction internal fixation in treating tibial plateau fractures.Methods:Data of patients with tibial plateau fracture admitted to West China Hospital of Sichuan University from January 2016 to December 2021 were retrospectively analyzed, and patients were divided into two groups according to treatment method: double traction-closed reduction internal fixation group (referred to as double traction group) and open reduction internal fixation group (referred to as open group). The double traction group included 21 patients, with 15 male and 6 female patients, with a mean age of 56.14±9.24 years (range, 45-72 years). Schatzker classification of fractures: 1 type I, 2 type II, 2 type III, 5 type IV, 6 type V, and 5 type VI. The open group included 29 patients, with 20 male and 9 female patients, with a mean age of 58.97±4.84 years (range, 47-70 years). Schatzker classification of fractures: 2 type I, 4 type II, 8 type III, 4 type IV, 5 type V, and 6 type VI. The surgical time, incision length, intraoperative blood loss, length of hospital stays, fracture healing time, postoperative time to full weight bearing, Rasmussen score, Hospital for Special Surgery (HSS) knee score, and complications were compared between the two groups of patients.Results:Both groups were followed up for 24 to 36 months, with an average of 30 months. There were significant differences in the operation time (92.61±6.22 min vs. 47.92±9.53 min), incision length (4.54±0.56 cm vs. 6.26±0.51 cm), and intraoperative blood loss (47.05±9.72 ml vs. 156.82±4.62 ml) between the group treated with closed reduction and double traction and the group treated with open reduction, with statistical significance ( t=18.83, 10.78, 53.24, P<0.001). There were also significant differences in the hospitalization time (5.35±0.41 d vs. 5.84±0.78 d), fracture healing time (3.72±0.74 months vs. 4.22±0.42 months), and time to full weight-bearing after surgery (11.29±1.10 weeks vs. 15.07±1.96 weeks) between the two groups, with statistical significance ( t=2.30, P=0.026; t=3.38, P<0.001; t=7.96, P<0.001). The HSS score at 6 months after surgery in the group treated with closed reduction and double traction was 81.61±2.32 points, which was higher than the score in the group treated with open reduction (77.66±4.01 points), with statistical significance ( t=4.07, P<0.001); at 12 months after surgery, the Rasmussen score in the group treated with closed reduction and double traction was 16.71±1.00 points, which was higher than the score in the group treated with open reduction (13.79±1.42 points), with statistical significance ( t=8.05, P<0.001). There was no fracture malunion or compartment syndrome occurred in both groups. The incidence of complications was 5% (1/21) in the group treated with closed reduction and double traction, and 10% (3/29) in the group treated with open reduction, with statistical significance (χ 2=0.52, P=0.473). Conclusion:The advantages of double traction-assisted reduction and internal fixation for tibial plateau fractures include minimal trauma, minimal bleeding, early mobilization, and shorter fracture healing time. It is a safe and reliable treatment method.

The ultra-high performance liquid chromatography coupled to time-of-flight mass spectrometry(UPLC-TOF-MS) and mass defect filter(MDF) were employed to analyze the metabolites of YQBYP in rat plasma, bile, urine and feces. Chromatographic separation was conducted on Acquity UPLC BEH C_(18) column(2.1 mm×100 mm, 1.7 μm) under gradient elution with 0.1% formic acid aqueous solution(A)-acetonitrile(B), and the column temperature was 30 ℃. Electrospray ion(ESI) source was used under positive and negative ion modes, with capillary voltage of 3.0 kV and mass scanning range of m/z 100-1 000. In this experiment, 9 prototype components and 36 metabolites were identified in rat plasma, bile, urine and feces samples. The results showed that the main metabolic pathways of YQBYP in rats involved methylation, demethylation, oxidation, and other phase Ⅰ reactions as well as glucuronidation, sulfation, and other phase Ⅱ reactions. This study provided scientific basis for clarifying the therapeutic material basis of YQBYP and product development.
