Objective To explore the short-term efficacy and safety of AngioJet mechanical thrombus removal,large lumen cathe-ter thrombus aspiration,and simple catheter-directed thrombolysis(CDT)for the treatment of acute deep venous thrombosis(DVT)of lower extremity.Methods A total of 75 patients with acute lower extremity DVT received interventional therapy were analyzed retrospectively,including 22 patients in AngioJet mechanical thrombus removal(group A),32 patients in large lumen catheter thrombus aspiration(group B),and 21 patients in simple CDT(group C).The short-term efficacy,health economics index,laboratory index and complications of the three groups were compared.Results The success rate of the three groups was 100％.Group A had superior thrombus clearance rates,lower dosages of urokinase,shorter thrombolysis durations,and shorter hospital stays compared to groups B and C.However,the hospitalization costs in group A were significantly higher than those in groups B and C,with statistically significant differences(P＜0.05).No significant renal dysfunction and severe complications were observed in the three groups.Post-operative creatinine levels in group A were higher than those in groups B and C,with statistically significant differences(P＜0.05).Both groups A and B experienced significant decreases in hematocrit postoperatively,and the absolute decrease and percentage decrease in hematocrit in group A were significantly greater than those in group C,with statistically significant differences(P＜0.05).Conclusion Compared to large lumen catheter thrombus aspiration and simple CDT treatment,AngioJet mechanical thrombus removal demonstrates higher efficiency in thrombus clearance rate but is associated with higher costs and risks of renal dysfunction.Postoperative care should focus on protecting renal function.

OBJECTIVE:To compare the clinical efficacy and radiological results of arthroscopic all-inside technique and traditional technique in anterior cruciate ligament reconstruction.METHODS:Databases such as CNKI,WanFang,VIP,PubMed,Web of Science,Embase,and Cochrane Library were searched for literature on all-inside technique and traditional technique in anterior cruciate ligament reconstruction.The search time was from the establishment of each database to September 2024.Meta-analysis was conducted on the included literature.RESULTS:(1)A total of 17 articles were included in the meta-analysis,with 631 patients in the all-inside technique reconstruction group and 626 patients in the traditional technique reconstruction group.The earliest time for the last follow-up was half a year after surgery,and the latest was 5 years after surgery.Most follow-up period was 2 years.(2)Meta-analysis results showed that compared with traditional anterior cruciate ligament reconstruction,the all-inside technique had a thicker graft during anterior cruciate ligament reconstruction[mean difference(MD)=0.20,95％confidence interval(CI)(0.09,0.31),P=0.000 5],smaller postoperative maximum diameter[standardized mean difference(SMD)=-3.64,95％CI(-6.00,-1.28),P=0.002]and volume[SMD=-3.69,95％CI(-5.37,-2.00),P＜0.000 1]of the tibial tunnel,and higher International Knee Documentation Committee subjective scores[MD=2.41,95％CI(0.49,4.32),P=0.01]and Lysholm scores[MD=1.11,95％CI(0.42,1.8),P=0.002]2 years after surgery.However,the operation time was relatively longer[MD=10.06,95％CI(4.71,15.4),P=0.000 2],and the knee stability was poorer after 2 years[SMD=0.3,95％CI(0.04,0.55),P=0.02].No significant differences were found between the two groups in the following aspects:the subjective scores of the International Knee Documentation Committee at 6 months and 1 year postoperatively[MD=-0.05,95％CI(-1.96,1.83),P=0.96;MD=0.51,95％CI(-1.17,2.19),P=0.55];the difference in anterior laxity of bilateral knees at 1 year postoperatively[SMD=-0.02,95％CI(-0.3,0.27),P=0.9];the Lysholm score at 6 months postoperatively[MD=0.87,95％CI(-0.15,1.89),P=0.09];the objective score of the International Knee Documentation Committee at the last follow-up[RR=0.95,95％CI(0.86,1.06),P=0.37];the American Knee Society Score at the last follow-up[MD=0.33,95％CI(-0.55,1.21),P=0.47];the Tegner score at the last follow-up[MD=0.05,95％CI(-0.11,0.22),P=0.53];the negative rate of the pivot shift test at the last follow-up[RR=0.92,95％CI(0.83,1.01),P=0.09];the postoperative revision rate at the last follow-up[RR=2.2,95％CI(0.98,4.92),P=0.05];and the result of the single-leg hop test at the last follow-up[MD=-0.06,95％CI(-4.99,4.86),P=0.98].CONCLUSION:There were no significant differences in most functional outcome scores and the position of the tibial tunnel between the all-inside technique and the traditional technique after anterior cruciate ligament reconstruction.The all-inside technique was more favorable in terms of subjective International Knee Documentation Committee scores and Lysholm scores at 2 years postoperatively.Meanwhile,the knee joint was more stable 2 years after anterior cruciate ligament reconstruction using the traditional technique.In addition,it was found that the graft was thicker during the all-inside technique,while the diameter and volume of the tibial tunnel were smaller postoperatively,with more bone tissue preserved.Nevertheless,the operation time of the all-inside technique was longer.

Objective To construct a predictive model for clinical pregnancy outcomes in frozen-thawed embryo transfer(FET)cycles in women with advanced maternal age(age≥35 years)and to analyze its influencing factors.Methods A retrospective analysis was conducted on the clinical data of 2717 older patients who underwent FET treatment at the First Affiliated Hospital of Kunming Medical University from January 2018 to December 2023.These Patients were divided into a clinical pregnancy group(n=851)and a non-clinical pregnancy group(n=1866)based on whether the clinical pregnancy had occurred.The general characteristics and transplantation details of the two groups were compared,and a logistic regression analysis model was constructed.Results The clinical pregnancy rate(CPR)was 31.32%.The CPR for women aged 35-40 years(40.06%)was higher than that for women aged≥40 years(19.35%),with a statistically significant difference(χ2=133.371,P<0.05).The model results showed that the higher anti-Mullerian hormone(AMH)levels(OR=1.053,95%CI:1.012-1.095),the more high-quality blastocysts were transferred(OR=1.704,95%CI:1.143-2.542;OR=2.861,95%CI:1.921-4.262);the more high-quality blastocysts were transferred(OR=2.033,95%CI:1.077-3.836;OR=3.886,95%CI:2.035-7.420),the thicker the endometrial lining on the day of transfer(OR=1.150,95%CI:1.092-1.212)and it could increase the probability of clinical pregnancy.However,for women over 40 years of age(OR=0.551,95%CI:0.437-0.694)and secondary infertility(OR=0.704,95%CI:0.552-0.896),the probability of clinical pregnancy would be reduced;ROC curve analysis results showed that the AUC for predicting clinical pregnancy occurrence in the training set and validation set of the predictive model were 0.723(95%CI:0.699-0.748)and 0.726(95%CI:0.689-0.764),respectively,with cutoff values of 0.262 and 0.260 and the model fit was good(P>0.05).Conclusion Female age,AMH level,type of infertility,number of high-quality embryos(cleavage embryos,blastocysts)transferred,and endometrial thickness on the day of transfer are important factors affecting FET cycles in advanced maternal age women.The constructed prediction model based on these factors has a certain predictive ability for clinical pregnancy.

Objectives:To investigate the predictive factors of stroke associated-pneumonia (SAP) in patients with acute stroke, develop nomogram and neural network prediction models and verify their predictive performance.Methods:Patients with acute stroke admitted to the First Affiliated Hospital of Kunming Medical University and Zhenxiong County People's Hospital were included retrospectively. Multivariate logistic regression analysis was used to determine the independent predictive factors of SAP, and develop nomogram and neural network prediction models. Receiver operating characteristic curve (ROC) curves were used to validate and compare the predictive performances. Results:A total of 450 patients with acute stroke were enrolled, including 286 males (63.6%), aged 64.28±13.24 years; 344 patientss (76.4%) had ischemic stroke and 106 (23.6%) had hemorrhagic stroke; 128 patients (28.4%) experienced SAP. According to the random number method, they were divided into a modeling cohort ( n=300) and a validation cohort ( n=150). Multivariate logistic regression analysis in the modeling cohort showed that a higher baseline National Institutes of Health Stroke Scale (NIHSS) score, gastric tube placement, use of proton pump inhibitors, heart failure, and higher neutrophil/lymphocyte ratio (NLR) were the independent predictive factors of SAP. ROC curve analysis showed that the area under the ROC curve of the nomogram model for predicting SAP in the modeling cohort and validation cohort was 0.841 (95% confidence interval [ CI] 0.795-0.880) and 0.863 (95% CI 0.798-0.914), respectively. The sensitivity for predicting SAP were 75.00% and 70.45%, respectively, and the specificity was 81.94% and 92.45%, respectively. The area under the ROC curve of the neural network model for predicting SAP in the modeling cohort and validation cohort was 0.847 (95% CI 0.802-0.866) and 0.862 (95% CI 0.796-0.913), respectively. The sensitivity for predicting SAP were 76.19% and 72.73%, and the specificity was 79.17% and 89.62%, respectively. Conclusions:Higher NIHSS score, gastric tube placement, use of proton pump inhibitors, heart failure, and higher NLR are the independent risk factors for SAP in patients with acute stroke. The nomogram and neural network prediction model developed using the above risk factors have higher predictive value for SAP.

Objective:To construct the impact factor model of primary traditional Chinese medicine (TCM) health management service quality, and put forward corresponding policy suggestions.Methods:In this cross-sectional study, the typical sampling and random sampling method were used to select 39 insiders of primary TCM health management service from 15 communities in Zhejiang Province from August to October in 2022. Interviews on service projects, implementation effects and impact factors were conducted, the three-level coding of interview record was carried out using the grounded theory research method, a model of impact factor for health management service quality of basic TCM was constructed, and the corresponding policy recommendations were put forward.Results:Based on the open coding of 39 original interview data, a total of 516 reference points were obtained, and 53 initial concepts related to the topic were formed and summarized into 17 first-level categories. Through the summary of main axis coding, 6 main categories of “policy environment”，“health literacy”，“community orientation”，“capacity building”，“health preference” and “conflict of interest” were extracted. The logical correlation between the six main categories were analyzed with selective coding, an impact factor model was constructed in accordance with the story line of factors affecting service quality. The story line of this model was as follows: first, the policy environment was the external guarantee of community TCM service quality; second, as the demand-side of the services, the health literacy and requirement of residents was the regulatory factor for service quality; in addition, the community played the role of the supply-side of the services, the service ability construction was the key factor, and the community functions and target orientation was the internal driving factor, meanwhile, the internal/external conflicts of interest had a negative constraint on the service quality.Conclusions:The guarantee intensity of external policy environment is limited, the service demand side pays insufficient attention, and the service supply side functions are absent at the present stage. It is necessary to improve the external policy environment, deepen the connection between supply and demand sides in the field of TCM health service, promote the capacity building of TCM service at the grass-roots level, balance the interests of relevant departments of TCM service, in order to improve the quality of TCM health management service at the grass-roots level.

Objective By comparison with the surgical resection,to evaluate the relapse-free survival(RFS),overall survival(OS),and clinical safety of transcatheter hepatic arterial chemoembolization(TACE)combined with microwave ablation(MWA)in the treatment of early primary hepatocellular carcinoma(HCC).Methods From January 2013 to January 2018 at authors'hospital,51 HCC patients received TACE combined with MWA(TACE+MWA group)and 58 HCC patients received surgical resection(RES group).The HCC lesions were single tumor with diameter ≤7 cm or multiple tumors with stage Ⅰ a-Ⅱ a meeting the"up-to-7"criteria.The postoperative RFS,OS,and clinical safety were compared between the two groups.Results The one-,3-and 5-year RFS in the TACE+MWA group were 84.3％,37.3％and 13.7％respectively,which in the RES group were 67.2％,27.6％and 13.8％respectively.The difference in the one-year RFS between the two groups was statistically significant(P=0.039),and the differences in the 3-and 5-year RFS between the two groups were not statistically significant(P=0.281 and P=0.992,respectively).The one-,3-and 5-year survival rates in the TACE+MWA group were 98％,62.7％and 45.1％respectively,which in the RES group were 94.8％,75.9％and 44.8％respectively,and the differences between the two groups were not statistically significant(P=0.704,P=0.137 and P=0.977 respectively).No treatment-related death occurred in both groups.In the TACE+MWA group,the main complications included transient embolism syndrome,abdominal pain during ablation procedure,and mild to moderate transient elevation of transaminase after treatment.In the RES group,the main postoperative complications included fever,pleural effusion,abdominal effusion,and intraoperative bleeding;and in one patient the postoperative liver function impairment worsened to Child grade C.The average cost of hospitalization in the TACE+MWA group was(39 834.98±6 717.38)Chinese yuan,which in the RES group was(49 042.59±11 810.69)Chinese yuan,the difference between the two groups was statistically significant(P=0.017).The hospitalization length in the TACE+MWA group was 23 days(19-28 days),which in the RES group was 21 days(17-25 days),and the difference between the two groups was not statistically significant(P=0.196).Conclusion For the treatment of early HCC,TACE combined with MWA has reliable curative effect,and also has the advantages of being safe and economical.Therefore,this therapy can be used as a preferred option of non-surgical treatment for single tumor with ≤7 cm diameter or multiple tumors with stage Ⅰ a-Ⅱa meeting"up-to-7"criteria.(J Intervent Radiol,2024,33:488-494)

Objective To discuss the clinical efficacy and safety of hepatic arterial infusion chemotherapy(HAIC)combined with carrelizumab and sorafenib in treating advanced hepatocellular carcinoma(HCC).Methods The clinical data of 36 HCC patients,who were admitted to the Affiliated Nantong Third Hospital of Nantong University of China to receive HAIC combined with carrelizumab and sorafenib from August 2019 to August 2020,were collected.According to modified Response Evaluation Criteria in Solid Tumors(mRECIST),the objective response rate(ORR)and disease control rate(DCR)of the combination therapy were evaluated.The Common Terminology Criteria Adverse Events Version 5.0 developed by American National Cancer Institute was used to evaluate the clinical safety.Results After receiving 4 cycles of FOLFOX-HAIC,the ORR and DCR of the patients were 38.9％and 77.8％respectively.The patients were followed up for 30 months.The median progression-free survival(mPFS)was 306 days(95％CI:242.7-369.3),and the median overall survival(mOS)was 515 days(95％CI:2 482.5-547.5).After HAIC treatment,one patient was successfully changed to surgical operation.The overall incidence of adverse events were 100％.There were 9 adverse events(25％)above grade m,including severe abdominal pain(n=2,5.6％),nausea(n=1,2.8％),vomiting(n=1,2.8％),elevated alanine aminotransferase(n=3,8.3％),elevated aspartate aminotransferase(n=1,2.8％),and death due to pulmonary failure caused by severe immune-induced pneumonia(n=1,2.8％).Conclusion For the treatment of advanced HCC,HAIC combined with carrelizumab and sorafenib has better ORR and DCR with controllable safety,which provides a new option for the treatment of advanced HCC.However,studies with large sample size need to be conducted before its long-term survival benefit of patients can be further validated.
