Objective To compare the clinical efficacy and safety differences between the triple immunosuppressive regimen of mizoribine (MZR) or mycophenolate mofetil (MMF) combined with tacrolimus (Tac) and glucocorticoids of kidney transplant recipients in one year after transplantation. Methods A single-center retrospective cohort study design was adopted. The clinical data of 156 patients who underwent the first allogeneic kidney transplantation at the Third Hospital of Peking University from January 2022 to December 2024 were included. The patients were divided into the MZR group (78 cases) and the MMF group (78 cases) based on the initial immunosuppressive regimen after transplantation. The baseline data, medication use in one year after transplantation, blood routine indicators, adverse events and clinical outcomes were compared between the two groups. For the repeated-measurement longitudinal data, repeated-measurement analysis of variance was used to evaluate the main effects of the groups, time and their interaction effects. Results At the primary efficacy endpoint, there were no statistically significant differences in the one-year survival rate, graft survival rate and incidence of acute rejection between the two groups (all P > 0.05). In terms of medication patterns and laboratory test indicators, there were significant time main effects and "time × group" interaction effects for Tac dosage (all P < 0.05). The Tac dosage in the MZR group was lower than that in the MMF group from 2 to 3 months after transplantation, and it was higher in the MZR group than in the MMF group from 7 to 12 months and one year after transplantation. White blood cell count in the MZR group was higher at one month after transplantation, and the platelet count was higher one year after transplantation (all P < 0.05). In terms of infection, the incidence of novel coronavirus and Pneumocystis jirovecii pneumonia infections in the MZR group was lower (all P < 0.05). In terms of metabolic indicators, the post-transplantation uric acid level was better in the MZR group than in the MMF group, but the total cholesterol level was higher one year after transplantation (all P < 0.05). In terms of liver function, there was a brief and mild increase in transaminase in the early stage after transplantation in the MZR group. Conclusions During the one-year follow-up after transplantation, both the MZR and MMF regimens demonstrate comparable immunosuppressive efficacy and overall safety in Chinese kidney transplant recipients. The MZR regimen shows clear advantages in reducing specific infection risks, alleviating bone marrow suppression and improving uric acid metabolism, but its potential impact on blood lipids needs to be monitored. Therefore, the MZR regimen may be an effective and safe alternative immunosuppressive option for kidney transplant recipients, especially those with high infection risk, poor hematological tolerance, or comorbid hyperuricemia.

Objective:To evaluate the short-and medium-term therapeutic efficacy of shockwave balloon therapy for TASCⅡ C/D femoropopliteal artery atherosclerosis obliteration.Methods:This retrospective cohort study included 25 patients who received shockwave balloon therapy in five vascular centers from August 2022 to June 2023. All patients were diagnosed with TASC Ⅱ C/D femoropopliteal arteriosclerosis obliterans (13 cases of type C and 12 cases of type D), and underwent intravascular shock wave lithotripsy (IVL) to treat calcified lesions. The immediate effectiveness (residual stenosis<30% and no flow-limiting dissection), safety (whether there were adverse vascular events during the operation) and the rate of salvage stent implantation were recorded. The observation indexes of patients before operation, early postoperative period (immediately after operation or before discharge) and postoperative follow-up period (3, 6, 12 months after operation) were collected. The observation indexes included ankle-brachial index (ABI), Rutherford classification, and minimum lumen diameter (MLD). Repeated measures ANOVA was used to evaluate the changes of observation indexes in the early postoperative and follow-up stages compared with those before operation; Kaplan-Meier survival analysis was used to evaluate the one-stage patency rate at follow-up and the target lesion revascularization rate free from clinical drive.Results:The immediate effectiveness of surgery was 100% in all patients, with no vascular related adverse events occurred, and no remedial stent implantation was performed. The ABI, Rutherford grade and MLD of the patients in the early postoperative period and each follow-up stage were improved compared with those before operation, with statistically significant differences ( P<0.05). Kaplan-Meier survival analysis showed that the primary patency rate at 12 months after surgery was 0.78 (95% CI 0.64-0.84), and the revascularization rate of target lesions free from clinical drive was 0.87 (95% CI 0.85-0.95). Conclusion:Shockwave balloon therapy for complex calcified femoropopliteal artery lesions is safe and reliable, with satisfactory short-and medium-term efficacy.

Objective To evaluate the role of preoperative serological indexes in predicting long-term survival and tumor recurrence of hepatocellular carcinoma (HCC) patients after liver transplantation, aiming to explore its significance in expanding the Milan criteria. Methods Clinical data of 669 recipients undergoing liver transplantation for HCC were retrospectively analyzed. The optimal cut-off value was calculated by the receiver operating characteristic (ROC) curve. The risk factors affecting the overall survival and recurrence-free survival rates of HCC patients after liver transplantation were identified by univariate and multivariate regression analyses. The correlation between preoperative serum liver enzymes and pathological characteristics in HCC patients was analyzed. The predictive values of alpha-fetoprotein (AFP) combined with γ -glutamyl transferase (GGT) and different liver transplant criteria for the survival and recurrence of HCC patients after liver transplantation were compared. Results Exceeded Milan criteria, total tumor diameter (TTD) > 8 cm, AFP > 200 ng/mL and GGT > 84 U/L were the independent risk factors for the overall survival and recurrence-free survival rates of HCC patients after liver transplantation (all P < 0.05). Correlation analysis showed that preoperative serum GGT level was correlated with TTD, number of tumor, venous invasion, microsatellite lesions, capsular invasion, tumor, node, metastasis (TNM) stage, Child-Pugh score and exceeded Milan criteria (all P < 0.05). Milan-AFP-GGT-TTD (M-AGT) criteria were proposed by combining Milan criteria, TTD with serum liver enzyme indexes (AFP and GGT). The 5-year overall survival and recurrence-free survival rates of HCC recipients who met the M-AGT criteria (111 cases of exceeded Milan criteria) were significantly higher than those who met Hangzhou criteria (both P < 0.05), whereas had no significant difference from their counterparts who met the University of California at San Francisco (UCSF) criteria (both P > 0.05). Conclusions Preoperative serological indexes of AFP and GGT could effectively predict the long-term survival and tumor recurrence of HCC patients after liver transplantation. Establishing the M-AGT criteria based on serological indexes contributes to expanding the Milan criteria, which is convenient and feasible.

OBJECTIVE To establish an evaluation syste m of clinical effec tiveness of Drug Selection Guideline for Medical Institutions，and to provide reference for drug selection in medical institution. METHODS Retrieved from relevant Chinese government websites ，PubMed，Embase，CBM and CNKI ，etc.，from the inception to Sept. 14th 2021，related contents of clinical effectiveness related to three secondary indicators ，such as “recommended level and strength of guideline ”“clinical pathway ”and “evidence and level of efficacy ”were extracted respectively ；evaluation system was construction for the clinical effectiveness. RESULTS A total of 5，4 and 17 policy documents or literatures were included according to “recommended level and strength of guideline”“clinical pathway ”and“evidence and level of efficacy ”，respectively.“The recommended level and strength of drug guideline”could reflect the clinical effectiveness of drugs ，and the evaluation content referred to the recommended level and strength of the selected drugs in the guidelines for corresponding indications. “Clinical pathway ”was the embodiment of drug effectiveness, and the evaluation content referred to the clinical path of whether the selected drugs were included in the corresponding indications. The evaluation contents of “evidence and level of efficacy ”were different between chemical medicine/ biological agent and Chinese patent medicine ；evidence and quality level of efficacy research for chemical medicine/biological agent referred to GRADE system ，while those for Chinese patent medicine referred to classic works or clinical experience inheritance. Therefore，the evaluation contents of this index system were the evidence and quality level of the efficacy research related to selected drugs. CONCLUSIONS The evaluation system of clinical effectiveness of drugs constructed from the perspective of drug selection in medical institutions can lay the foundation of evaluation system for the construction of Drug Selection Guideline for Medical Institutions ，and also provide reference for drug selection in medical institutions.

To compare the incidence of hypoglycemia between day-before bowel preparation and split-dose bowel preparation in colonoscopy patients. The effects of enterald ietary nutrients on the prevention of hypoglycemia and the preparation quality of the intestine during colonoscopy were compared. The patients who underwent colonoscopy were divided into the day-before bowel preparation group, the split-dose bowel preparation group, and the split-dose bowel preparation + enteral nutrient diet group. All patients had their finger blood sugar tested before colonoscopy. The peripheral blood glucose level was measured before operation. After the endoscopic examination, the intestinal cleanliness of the patients was evaluated through the Boston intestinal preparation scale by endoscopists. The incidence of day-before bowel preparation group and split-dose bowel preparation group and enteral nutrient intervention group were 14.38%(23/160), 17.50% (28/160)and 6.45% (4/62), respectively. The proportions of high quality intestinal cleaning were 31.25% (50/160), 35.00% (56/160) and 82.26% (51/62) in the three groups respectively. The incidence of hypoglycemia was higher in split-dose bowel preparation group than that in day-before bowel preparation group. Enteral nutrient intervention can effectively reduce the incidence of hypoglycemia and improve the quality of intestinal preparation, which is a recommended intestinal preparation method.

Objective: By investigating the genotype and evolutionary variation of hantavirus (HV) in Tiantai county, a national surveillance site for hemorrhagic fever with renal syndrome (HFRS) was set in Zhejiang province, from 2011 to 2018, to reveal the molecular epidemiological characteristics of hantavirus (HV) in Tiantai. Methods: Total RNA was extracted from ultrasound treated HV antigen- positive rat lung samples in Tiantai from 2011 to 2018. After cDNA was prepared, nested PCR was used to amplify partial sequence of M fragments by using specific primers of HV. The sequences of HV in Tiantai from 2011 to 2018 were compared with other known HV sequences in order to identify the genotype and analyze the evolution and variation of the virus. Results: In 67 HV antigen-positive lung specimens, 31 were positive in nested PCR amplification with type-specific primers, including 30 Hantaan virus (HTNV) positive samples, 1 Seoul virus (SEOV) positive sample, and all the 31 samples were from Apodemus agrarius. The phylogenetic tree based on partial M segment was divided into monophyletic group, 30 strains were distributed in HTNV group and 1 was in SEOV group. The HTNV strain Tiantai T2018-130 was independently in one branch, sharing 84.8%-87.9% homology with other strains both at home and abroad, including 29 strains in HTNV group in Tiantai. The other 29 HTNV strains in Tiantai showed closer relationship. The SEOV strain T2016-31 from Apodemus agrarius showed closer relationship with previous strains of SEOV, Tiantai ZT71, ZT10 and Z37 strains of Wenzhou, Zhejiang province. Conclusions HTNV, the main genotype of HV in Tiantai of Zhejiang province, showed obvious geographic clustering, but the strain T2018-130 was distinct from the others in Tiantai. Meanwhile, by sequence analysis, we confirmed that The SEOV strain T2016-31 existed in in Apodemus agrarius, indicating there was a phenomenon of "spillover" between virus and host in SEOV evolution.

Objective To compare the hemostatic safety and efficacy of a new butterfly femoral artery compression device (FACD) with those of manual compression (MC) in patients undergoing percutaneous peripheral endovascular interventions via femoral artery. Methods A total of 283 patients, who received percutaneous endovascular interventions via femoral artery during the period from September 2016 to December 2017, were enrolled in this study. After endovascular intervention, 167 patients received FACD to make hemostasis (FACD group), and 116 patients received MC hemostasis (MC group) . The patient's comfortableness, time used for hemostasis (min), limb immobilization time (h), and the incidence of vascular complications in both groups were analyzed. Results All 283 patients were included in analysis, the results indicated that the hemostatic success rates in FACD group and MC group were 96.4％ (161/167) and 94.0％ (109/116) respectively, the difference between the two groups was not statistically significant (P>0.05) . The postoperative Kolcaba Comfort Scale score of FACD group was (85.0 ±11.2) points, which was remarkably higher than (58.4±11.7) points of MC group (P<0.05), the time used for hemostasis in FACD group was (9.2 ±2.2) min, which was strikingly shorter than (18.5 ±2.9) min in MC group (P <0.05) . The limb immobilization time in FACD group was (10.4±2.4) hours, which was obviously shorter than (23.1±4.1) hours in MC group (P <0.05) . The incidence of vascular complications in FACD group was 3.6％, which was dramatically lower than 9.5％ in MC group (χ2=4.206, P=0.04) . Conclusion The use of the new butterfly FACD can promptly, safely and effectively stop bleeding of femoral artery puncture site. The new butterfly FACD is superior to MC in shortening hemostatic time and limb immobilization time, in reducing incidence of vascular complications, as well as in improving patient's comfortableness degree.
