Objective:To clarify the current status of mechanical ventilation management in critically ill patients and identify prognostic risk factors in Xinjiang Uygur Autonomous Region, thereby providing evidence for targeted training programs and quality improvement initiatives.Methods:A cohort study was conducted across multiple ICUs in Xinjiang Uygur Autonomous Region from January 31 to February 1, 2024. Patients receiving mechanical ventilation during the study period were enrolled, with clinical outcomes followed up until February 28, 2024. Statistical analyses included demographic characteristics, therapeutic interventions, laboratory parameters, and medication regimens.Results:A total of 77 ICUs and 727 patients were screened in the study, and 253 (34.80%) patients who received mechanical ventilation were ultimately included. Among these patients, 177 patients (69.96%) were treated in tertiary hospitals, and 76 patients (30.04%) in secondary hospitals. Significant differences were observed between tertiary and secondary hospitals regarding ventilator mode selection and mechanical ventilation parameter settings (all P<0.05). No significant differences were found in the 28-day mortality rate between tertiary hospitals and secondary hospitals (33.9% vs. 43.4%, P=0.194). Compared with patients in the survival group, death group patients were older and had more severe disease severity. Multivariate Cox regression analysis demonstrated that body temperature ( HR=1.573, 95% CI: 1.173-2.110, P=0.003), white blood cell count ( HR=1.048, 95% CI: 1.012-1.084, P=0.008), pH ( HR=0.019, 95% CI: 0.001-0.349, P=0.007), age > 65 years ( HR=1.817, 95% CI: 1.086-3.041, P=0.023), and fraction of inspired oxygen ≥ 60% ( HR=2.072, 95% CI: 1.143-3.757, P=0.016) were independent influencing factors for 28-day mortality in mechanically ventilated patients. Conclusions:Mechanically ventilated patients are a major component of the ICU population in Xinjiang Uygur Autonomous Region, with the characteristics of high risk of death. The clinical practice of mechanical ventilation in this region is heterogeneous. In the future, it is urgent to strengthen the improvement of medical quality and related training to improve the success rate of patients with mechanical ventilation.

ObjectiveTo observe the effect of bee acupuncture therapy on clinical symptoms and signs， as well as the level of inflammatory cytokine interleukin-6 （IL-6） in synovial fluid of patients with knee osteoarthritis. MethodsThe 94 patients with knee osteoarthritis were divided into the control group and the trial group by the random number table method， with 47 cases in each group. Both groups were given one tablet （60 mg） of etoricoxib orally every morning for 2 weeks. The control group also received microneedle shallow acupuncture therapy， once a day for 5 consecutive times followed 2-day pause， and continued 5 consecutive times， as a course of treatment； the trial group was treated with bee acupuncture therapy once every 2 days， 2 times a week， and 4 times as a course of treatment. Both groups have a course of treatment for 2 weeks. The changes in clinical symptoms and signs of patients in the two groups were observed and evaluated before treatment， after 1- and 2-week treatment， and 12-week follow-up and the differences in Lequesne index scores， HSS scores， Visual Analogue Scale （VAS） scores and IL-6 levels in knee synovial fluid between the two groups of patients were also compared. ResultsNo patients lost to follow up in either group. The Lequesne index scores and VAS scores were lower， and the HSS scores were higher in both groups at all time points after treatment compared with those before treatment （P＜0.05）. Compared at the same time after treatment， the Lequesne index scores and VAS scores of the trial group were lower than those of the control group， and the HSS scores were higher than those of the control group （P＜0.05）. IL-6 in synovial fluid was lower in the trial group at the 12-week follow-up than before treatment （P＜0.05）， but there was no significant difference between two groups at each time point（P＞0.05）. ConclusionBee acupuncture therapy for knee osteoarthritis can significantly improve clinical signs and symptoms， but has no significant effect on the level of IL-6 in knee synovial fluid.

Objective In order to address the issues of inconvenience,high medical costs,and lack of universality associated with traditional knee rehabilitation equipment,a portable intelligent wheelchair for knee rehabilitation was designed in this study.Methods Based on the analysis of the knee joint's structure and rehabilitation mechanisms,an electric pushrod-driven rehabilitation institution was developed.A multi-functional module was designed with a modular approach,and the control of the wheelchair body and each functional module was implemented using an STM32 single-chip microcomputer.A three-dimensional model was established using SolidWorks software.In conjunction with Adams and Ansys simulation software,kinematic and static analyses were conducted on the knee joint rehabilitation institution and its core components.A prototype was constructed to verify the equipment's actual performance.Results According to the prototype testing,the actual range of motion for the knee joint swing rod is 15.1°～88.9°,the angular speed of the swing rod ranges from-7.9 to 8.1°/s,the angular acceleration of the swing rod varies from-4.2 to 1.6°/s2,the thrust range of the electric pushrod is-82.6 to 153.1 N,and the maximum displacement of the load pedal is approximately 1.7 mm,with the leg support exhibiting a maximum deformation of about 1.5 mm.Conclusion The intelligent knee joint rehabilitation wheelchair meets the designed functions and its actual performance aligns with the design criteria,thus validating the rationality and feasibility of the structural design.

Non-small cell lung cancer(NSCLC)remains a significant global health burden,and there is an urgent need for new treatment options.Trophoblast cell surface antigen-2(TROP-2),a target closely associated with NSCLC prog-nosis,has become a research hotspot in recent years.Notably,TROP-2-targeted antibody-drug conjugates(ADCs)have made groundbreaking advances in NSCLC therapy.Clinical studies have demonstrated that certain TROP-2 ADCs can significantly improve progression-free survival in previously treated patients with advanced or metastatic NSCLC,regardless of the presence of actionable genomic alterations.These agents have shown promising potential in both frontline and subsequent treatment settings.In terms of safety,while adverse effects affecting the hematologic,respiratory,and gastrointestinal systems are gener-ally manageable,close clinical monitoring and timely management are still required.In conclusion,TROP-2 ADCs hold great promise in the treatment of NSCLC.

Background::Although the treatment of peripheral T-cell lymphoma (PTCL) has undergone advancements during the past several years, the response rate and long-term effects with respect to patients with PTCL remain unsatisfactory—particularly for relapsed or refractory (R/R) patients. This phase II trial was designed to explore the efficacy and safety of an all-oral regimen of chidamide plus prednisone, cyclophosphamide, and thalidomide (CPCT) for R/R PTCL patients who could not tolerate the standard chemotherapy for a variety of reasons.Methods::We conducted a multicenter phase II clinical trial in which we combined chidamide (30 mg twice weekly) with prednisone (20 mg daily after breakfast), cyclophosphamide (50 mg daily after lunch), and thalidomide (100 mg daily at bedtime) (the CPCT regimen) for a total of fewer than 12 cycles as an induction-combined treatment period, and then applied chidamide as single-drug maintenance. Forty-five patients were ultimately enrolled from August 2016 to April 2021 with respect to Chinese patients at nine centers. Our primary objective was to assess the overall response rate (ORR) after the treatment with CPCT.Results::Of the 45 enrolled patients, the optimal ORR and complete response (CR)/CR unconfirmed (CRu) were 71.1% (32/45) and 28.9% (13/45), respectively, and after a median follow-up period of 56 months, the median progression-free survival (PFS) and overall survival (OS) were 8.5 months and 17.2 months, respectively. The five-year PFS and OS rates were 21.2% (95% confidence interval [CI], 7.9-34.5%) and 43.8% (95% CI, 28.3-59.3%), respectively. The most common adverse event was neutropenia (20/45, 44.4%), but we observed no treatment-related death.Conclusion::The all-oral CPCT regimen was an effective and safe regimen for R/R PTCL patients who could not tolerate standard chemotherapy for various reasons.Trial Registration::ClinicalTrials.gov, NCT02879526.

Objective:To explore the value of baseline PET/CT parameters for predicting prognosis in patients with double-expression lymphoma (DEL).Methods:The clinical and 18F-FDG PET/CT data of 118 patients (66 males, 52 females; age: 28-85 years) with diffuse large B-cell lymphoma (DLBCL) diagnosed in Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University and the First Affiliated Hospital of Nanjing Medical University from June 2015 to September 2022 were retrospectively analyzed. The optimal thresholds for SUV max, total metabolic tumor volume (TMTV) and total lesion glycolysis (TLG) in predicting overall survival (OS) rate were determined using ROC curve analysis. Univariate and multivariate analyses, along with Kaplan-Meier survival analysis were performed to construct a survival prediction model. The effect of the model was evaluated by the calibration curve for the model, the time-dependent ROC curve analysis and decision curve analysis. Results:As of the last follow-up, 25 patients died, and the OS rate was 78.8%(93/118). The AUC of the ROC curve for TMTV was 0.705, with a corresponding optimal threshold of 230.9 cm 3. In multivariate analysis, Eastern Cooperative Oncology Group performance status (ECOG PS) score (hazard ratio ( HR)=3.886, 95% CI: 1.455-10.375; P=0.007) and TMTV ( HR=4.649, 95% CI: 1.665-12.979; P=0.003) were identified as independent predictors of OS. The combined model of ECOG PS score and TMTV was superior to ECOG PS score model and TMTV model alone in predicting OS. Conclusion:TMTV, a metabolic indicator, and ECOG PS score, a clinical risk factor, are independent predictors of OS in patients with DEL, and their combination can provide more accurate prognostic predictions.

[Objective]To explore the micro-ecological mechanism of soil amendment combined with Trichoderma solution in resolving the replant obstacles of Atractylodes macrocephala through studying their effects on the microbial community structure in the rhizosphere soil.[Methods]In pot experiment and field experiment,different soil amendments and Trichoderma inoculants were applied to Atractylodes macrocephala,the survival rate,physiochemical properties of soil and microbial community were detected,as well as analysis of the microenvironmental changes in the rhizosphere.[Results]The number of leaves and survival rate were significantly increased after the application of lime(mainly composed of calcium oxide)and mixed bacterial solution;the activity of soil-urease(S-UE),soil-phosphatase(S-NP),solid-β-glucosidase(S-β-GC),soil-catalase(S-CAT)in the rhizosphere were also increased,indicating that the replant obstacle was alleviated.Meanwhile,the rhizosphere bacteria and fungi were the highest.The sequencing results showed that the bacteria in the rhizosphere soil after the application of lime and mixed bacterial solution were mainly composed of Gemmatimonadetes,Verrucomicrobia,Firmicutes,Actinobacteria,while the fungi were mainly composed of Ascomycetes,Mortierella,Basidiomycetes and Chytridiomycota,after the application of lime and mixed bacterial solution,the proportion of Fusarium decreased,and the proportion of Penicillium increased.[Conclusion]The combination of lime as a soil amendment and Trichoderma can effectively improve the replant disorder of Atractylodes macrocephala and promote the growth of Atractylodes macrocephala,which may be by improving the structure of the microbial communities in the rhizosphere,increasing the abundance of biocontrol bacteria and reducing the abundance of pathogenic bacteria.

Objective To observe the effect of different muscle relaxation depth on optic nerve sheath diameter(ONSD)in obese patients undergoing laparoscopic sleeve gastrectomy.Methods A total of 56 obese patients undergoing elective laparoscopic sleeve gastrectomy under general anesthesia in this hospital from March to June 2023 were selected and randomly divided into the deep muscle relaxation group(group D)and moderate muscle relaxation group(group M),28 cases in each group.According to the TOF-Watch muscle re-laxation monitor,group D maintained the train of four(TOF)stimulation count as 0,moreover the post-tetan-ic count(PTC)count was 1-2,and group M maintained TOF count as 1-2.The operation time,anesthesia time and rocuronium bromide dosage were recorded.ONSD,MAP and HR at 5 min after induction intubation(T0),5 min after pneumoperitoneum establishment(T1),30 min after pneumoperitoneum establishment(T2),90 min after pneumoperitoneum establishment(T3),and 5 min after the end of pneumoperitoneum(T4)were recorded,and the occurrence of postoperative adverse reactions such as dizziness and vomiting were recorded.Results There were statistical differences in ONSD at T2 and T3 between the two groups(P＜0.05),ONSD in the group D was significantly reduced and the anesthetic time was significantly prolonged compared with the group M(P＜0.05),the dosage of rocuronium bromide in the group D was significantly increased compared with that in the group M(P＜0.05).There was no statistically significant difference in MAP and HR at T0-T4 between the two groups(P＞0.05).One case developed severe hypoxemia after sur-gery.Conclusion Compared with moderate muscle relaxation,deep muscle relaxation could alleviate the intra-operative enlargement of ONSD in obese patients undergoing laparoscopic sleeve gastrectomy.

Objective:To explore the prognostic value of 18F-FDG PET-based radiomics features by machine learning in older patients(≥60 years) with diffuse large B-cell lymphoma (DLBCL). Methods:A total of 166 older patients (88 males, 78 females, age: 60-93 years) with DLBCL who underwent pre-therapy 18F-FDG PET/CT from March 2011 to November 2019 were enrolled in the retrospective study. There were 115 patients in training cohort and 51 patients in validation cohort. The lesions in PET images were manually drawn and the obtained radiomics features from patients in training cohort were selected by the least absolute shrinkage and selection operator (LASSO), random forest (RF), and extreme gradient boosting (Xgboost), and then classified by support vector machine (SVM) to build radiomics signatures (RS) for predicting overall survival (OS). A multi-parameter model was constructed by using Cox proportional hazard model and assessed by concordance index (C-index). Results:A total of 1 421 PET radiomics features were extracted and 10 features were selected to build RS. The univariate Cox regression analysis showed that RS was a predictor of OS (hazard ratio ( HR)=5.685, 95% CI: 2.955-10.939; P<0.001). The multi-parameter model that incorporated RS, metabolic metrics, and clinical risk factors, exhibited significant prognostic superiority over the clinical model, PET-based model, and the National Comprehensive Cancer Network International Prognostic Index (NCCN-IPI) in terms of OS (training cohort: C-index: 0.752 vs 0.737 vs 0.739 vs 0.688; validation cohort: C-index: 0.845 vs 0.798 vs 0.844 vs 0.775). Conclusions:RS can be used as a survival predictor for older patients(≥60 years) with DLBCL. Furthermore, the multi-parameter model incorporating RS is able to successfully predict prognosis.

Hyperuricemic nephropathy （HN）， a secondary renal damage common in clinical practice， is characterized by early concealing and continuous progression. The understanding of HN in traditional Chinese medicine （TCM） is from a macroscopic perspective. According to the TCM theory， HN is caused by the combination of external pathogens and internal injuries， with the main pathogenesis being root deficiency combined with superficial excess and deficiency-excess in complexity. In western medicine， the understanding of HN is from the microscopic perspective， which holds that the occurrence of HN is the result of inflammation， oxidative stress， renin-angiotensin-aldosterone system （RAAS） activation， and metabolic abnormalities. The TCM syndromes of HN include internal dampness and heat， obstruction in dampness and turbidity， deficiency of spleen and kidney， and deficiency of kidney yin. Accordingly， the prescriptions should clear heat and dampness， remove dampness and turbidity， tonify spleen and kidney， and nourish kidney yin， respectively. In addition to TCM prescriptions， single herbal medicines and their extracts， Chinese patent medicines， and external applications of Chinese medicines have played a significant role in the treatment of HN， promoting the application of TCM in the treatment of HN. Moreover， the integrated traditional Chinese and western medicine has also played a role in the treatment of HN， enriching the treatment schemes of HN. Different from common kidney diseases such as acute and chronic glomerulonephritis and nephrotic syndrome， HN with particularity should be carefully differentiated in clinical practice. This article systematically summarizes the research progress in the treatment of traditional Chinese medicine and integrated traditional Chinese and western medicine on hyperuricemic nephropathy with TCM and integrated traditional Chinese and western medicine， aiming to enrich the system and theory of HN treatment and further guide the clinical practice.
