OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective To investigate the feasibility of left atrial appendage closure(LAAC)in patients with atrial fibrillation combined with persistent left atrial appendage(LAA)thrombus.Methods The authors searched PubMed,EBSCO,CNKI and WANFANG DATA for all abstracts or full-text articles investigating LAAC in patients with atrial fibrillation combined with persistent LAA thrombus from 1 January 2000 to 1 June 2023.Baseline clinical characteristics,procedure-related data and perioperative complications,and clinical outcomes at follow-up were collected.The pooled data were analysed.Results 278 patients with atrial fibrillation combined with persistent LAA thrombus were retrospectively included.The average age was 73.2 years,58.6％male,the mean CHA2DS2-VASc and HAS-BLED scores was(4.62±1.23)and(3.28±0.94),respectively.In patients with previous stroke,ischaemic stroke/transient ischaemic attack(TIA)accounted for 74.8％.Most of the patients had a distally located thrombus in the LAA.All cases underwent successful implantation of LAAC devices with some procedural modifications.Amulet was the most commonly used device(65％).A cerebral protection device was used in 118(42.4％)patients.Most LAAC procedures were underwent with some technical modifications.One TIA(0.36％)and 3(1.08％)mild pericardial effusion that did not require drainage occurred post-procedure.There were 3 major bleeding events,and 2 of them required blood transfusion.The mean follow-up was(6.2±7.1)months,with 238 patients followed up.The all-cause mortality was 1.68％(4/238).Four ischemic strokes(4/238,1.68％)and 12(12/238,5.04％)device-related thrombus were noted during the follow-up.Conclusions Percutaneous LAAC procedures appear to be feasible in patients with persistent LAA thrombus when performed by experienced operators with some technical modifications and chose appropriate type of closure device according to the location of thrombus in the LAA.

Objective:To investigate the factors related to hypothyroidism induced by programmed death(PD)-1 treatment in elderly patients with cancer.Methods:A total of 193 older patients(≥60 years old)with advanced solid tumors who received PD-1 treatment between January 2018 and January 2021 at the Department of Oncology of Xiangyang Central Hospital were included in this study.The patients were divided into two groups based on whether they were diagnosed with hypothyroidism after PD-1 treatment: the hypothyroidism group(36 cases)and the non-hypothyroidism group(157 cases).The clinical data of both groups, including age, gender, Eastern Cooperative Oncology Group performance status(ECOG PS), PD-1 inhibitors, thyroid function, and thyroid antibody, were compared to analyze the risk factors associated with hypothyroidism.Results:Among the 193 patients, 36(18.7%)were diagnosed with hypothyroidism.The study found no significant differences between the two groups in terms of age, gender, ECOG PS, tumor type, and PD-1 type(all P>0.05).However, significant differences were observed in the baseline levels of thyroid stimulating hormone(TSH)and thyroid antibody subgroups(both P<0.05).The results of multivariate Logistic regression analysis revealed that the presence of baseline anti-thyroid peroxidase antibody(TPOAb)( OR=20.256, 95% CI: 5.709-71.868, P<0.001), the presence of both baseline thyroglobulin antibody(TGAb)and TPOAb( OR=5.853, 95% CI: 1.475-23.227, P=0.012), and an increase in baseline TSH levels( OR=3.065, 95% CI: 1.049-8.959, P=0.041)were identified as risk factors for hypothyroidism induced by PD-1 treatment.On the other hand, there was no significant association between the presence of baseline TGAb and the occurrence of hypothyroidism( OR=1.373, 95% CI: 0.353-5.341, P=0.648). Conclusions:The incidence rate of hypothyroidism induced by PD-1 inhibitors is high among elderly patients with cancer.Additionally, the risk of hypothyroidism is higher in patients with elevated baseline TSH and positive TPOAb.Therefore, it is crucial to remain vigilant for the occurrence of hypothyroidism during PD-1 treatment.Timely diagnosis and treatment of hypothyroidism are necessary to minimize the incidence of adverse events.

Objective:To explore the efficacy of cerebral vasospasm model established by brief double blood injection in cisternal cisteria.Methods:Twenty-five SD rats were randomly divided into sham-operated group, group of 1 d after subarachnoid hemorrhage (SAH), group of 3 d after SAH, group of 5 d after SAH, and group of 7 d after SAH ( n=5). Autologous blood (0.2 mL, obtained by caudal artery puncture) was directly injected into the atlanto-occipital membrane and repeated 48 h after that to establish cerebral vasospasm model. Neurological impairment was evaluated by modified Neurological Severity Score (mNSS). Diameter and cross-sectional area of the basilar artery (BA) were detected by HE staining. Differences of body mass before modeling, body mass between the 2 blood injections, mNSS scores, and diameter and cross-sectional area of BA were compared among groups. Results:(1) Body mass before modeling was not significantly different among the 5 groups ( P>0.05); differences of body mass between the 2 blood injections in the group of 1 d after SAH, group of 3 d after SAH, group of 5 d after SAH, and group of 7 d after SAH were significantly greater than those in the sham-operated group ( P<0.05). (2) The mNSS scores in the group of 1 d after SAH, group of 3 d after SAH, group of 5 d after SAH, and group of 7 d after SAH were significantly higher than those in the sham-operated group ( P<0.05). (3) BA diameter in the group of 3 d after SAH and group of 7 d after SAH was significantly shorter than that in the sham-operated group, and that in the group of 7 d after SAH was significantly shorter than that in the group of 1 d after SAH and group of 5 d after SAH ( P<0.05). BA cross-sectional area in the group of 1 d after SAH, group of 3 d after SAH, group of 5 d after SAH and group of 7 d after SAH was significantly smaller than that in the sham-operated group, and that in the group of 7 d after SAH was significantly smaller than that in the group of 1 d after SAH, group of 3 d after SAH and group of 5 d after SAH ( P<0.05). Conclusion:Compared with other traditional models, cerebral vasospasm model established by brief double blood injection in cisternal cisteria has advantages of simplified operation, short modeling time, and minimal invasion; model of 7 d after autologous blood injection enjoys optimal.

Objective:To investigate the CD163 expression characteristics in intracranial aneurysm (IA) tissue and blood of patients with IA and its feasibility as an early clinical screening indicator for IA.Methods:A total of 28 patients with IA admitted to Department of Neurosurgery, First Affiliated Hospital of Xinjiang Medical University from January 2021 to November 2023 were selected as IA group, and 28 healthy subjects from Health Management Center, First Affiliated Hospital of Xinjiang Medical University at the same time period were selected as control group. Eight saccular IA tissues and 12 superficial temporal artery tissues were collected from patients from IA group accepted IA clipping, and real-time fluorescent quantitative PCR (RT-qPCR) was used to detect the CD163 mRNA expression in these tissues. RT-qPCR was also used to detect the CD163 mRNA expression in the blood of the 2 groups. Seven patients with IA and 7 control subjects from the above 2 groups were randomly selected, respectively; and plasma CD163 protein content was detected by enzyme-linked immunosorbent assay (ELISA). Multivariate Logistic regression was used to analyze the influencing factors for IA. Receiver operating characteristic (ROC) curve was used to analyze the diagnostic values of blood CD163 mRNA expression and plasma CD163 protein content in IA. Results:CD163 mRNA expression in IA tissues was significantly higher than that in superficial temporal artery tissues (41.870±20.355 vs. 6.080±5.444, P<0.05). CD163 mRNA expression in the blood of IA patients was significantly higher than that in the controls (1.969[1.124, 2.318] vs. 1.124[0.933, 1.379], P<0.05). CD163 mRNA expression in the blood of ruptured IA group, unruptured IA group, and control group was gradually decreased, with significant differences ( P<0.05). CD163 mRNA expression in the blood of female IA patients was not statistically different compared with that in male IA patients ( P>0.05). ELISA showed that the CD163 protein content in plasma of the IA group was significantly higher than that in the control group [10.537±1.879] ng/L vs. [8.598±0.885] ng/L, P<0.05). Multivariate Logistic regression analysis showed that age and CD163 mRNA expression in the blood were independent influencing factors for IA occurrence ( OR=0.844, 95% CI: 0.750-0.951, P=0.005; OR=0.111, 95% CI: 0.024-0.506, P=0.004). ROC curve showed that the area under the curve (AUC) of CD163 mRNA expression in blood in diagnosing IA was 0.759 (95% CI: 0.618-0.890, P=0.002), and that of CD163 protein content in plasma in diagnosing IA was 0.864 (95% CI: 0.610-1.000, P=0.035). Conclusion:CD163 mRNA expressions in blood and IA tissues and CD163 protein content in plasma are high in patients with IA; CD163 mRNA expression in blood is an independent risk factor for IA; CD163 protein in plasma can be used as a molecular marker for screening IA.

Objective:To evaluate the clinical effectiveness of vacuum sealing drainage(VSD)in the treatment of severe scro-tal infectious diseases and to summarize the practical experience obtained during its implementation.Methods:Clinical data from 9 patients with severe scrotal infectious diseases were compiled.All patients underwent debridement assisted by a VSD device in addition to conventional treatment measures.Results:Following debridement with VSD device,combined with systemic anti-infection treat-ment and nutritional support,all patients exhibited favorable therapeutic outcomes,with no fatalities.The average duration of debride-ment was 81±27 minutes.One patient necessitated secondary debridement and skin grafting,while another was transferred to the ICU due to septic shock.Conclusions:The application of VSD device can streamline the treatment process for severe scrotal infectious diseases,alleviate patient discomfort,and promote patient recovery.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective To evaluate the safety and efficacy of intravascular lithotripsy(IVL)in the treatment of coronary artery calcification lesions.Methods A total of 53 patients who underwent endovascular imaging guided treatment of coronary artery calcified lesions with either IVL or cutting balloon(CB)at the Affiliated Hospital of Jining Medical College from January 2023 to July 2023 were retrospectively analysed(IVL:n=18,CB:n=35)were retrospectively analysed to compare the technique,clinical success rate,major adverse cardiovascular events(MACE)and readmission for cardiovascular events in patients followed during hospitalisation and 1 month after the procedure.Results Clinical success rates were identical in the IVL and CB groups(100.0％vs.100.0％,P＞0.999),the minimum lumen area of lesions was similar in the VL and CB groups[(1.7±0.4)mm2 vs.(1.7±0.5 mm2),P=0.628].And there was a statistically significant difference in the overall mean lesion length between the IVL and CB groups[(28.4±9.6)mm vs.(20.9±8.6)mm,P=0.008].During the procedure,there were no complications such as aneurysm,thrombus,or emergency vessel closure.There was a statistically significant difference in the overall mean value of residual stenosis between the IVL and CB groups[(1.7±1.7)％vs.(6.9±2.0)％,P=0.049].There were no MACE in either group during hospitalisation or at the one-month follow-up(0 vs.0,P＞0.999),and 3 patients in the CB group were readmitted for angina pectoris(0 vs.8.6％,P=0.543),with no significant difference in readmission rates between the two groups.Conclusions The technique of intravascular lithotripsy is safe and effective in the treatment of coronary artery calcification lesions.

BACKGROUND: Rheumatoid arthritis (RA), a chronic systemic autoimmune disease, is characterized by synovitis and progressive damage to the bone and cartilage of the joints, leading to disability and reduced quality of life. This study was a randomized clinical trial comparing the outcomes between withdrawal and dose reduction of tofacitinib in patients with RA who achieved sustained disease control. METHODS: The study was designed as a multicenter, open-label, randomized controlled trial. Eligible patients who were taking tofacitinib (5 mg twice daily) and had achieved sustained RA remission or low disease activity (disease activity score in 28 joints [DAS28] ≤3.2) for at least 3 months were enrolled at six centers in Shanghai, China. Patients were randomly assigned (1:1:1) to one of three treatment groups: continuation of tofacitinib (5 mg twice daily); reduction in tofacitinib dose (5 mg daily); and withdrawal of tofacitinib. Efficacy and safety were assessed up to 6 months. RESULTS: Overall, 122 eligible patients were enrolled, with 41 in the continuation group, 42 in the dose-reduction group, and 39 in the withdrawal group. After 6 months, the percentage of patients with a DAS28-erythrocyte sedimentation rate (ESR) of <3.2 was significantly lower in the withdrawal group than that in the reduction and continuation groups (20.5%, 64.3%, and 95.1%, respectively; P  < 0.0001 for both comparisons). The average flare-free time was 5.8 months for the continuation group, 4.7 months for the dose reduction group, and 2.4 months for the withdrawal group. CONCLUSION: Withdrawal of tofacitinib in patients with RA with stable disease control resulted in a rapid and significant loss of efficacy, while standard or reduced doses of tofacitinib maintained a favorable state.

Objective:To evaluate the safety and efficacy of trimodality treatment (TMT) which is complete transurethral resection of bladder tumor with concurrent radiotherapy and chemotherapy for invasive bladder cancer.Methods:From Mar. 2016 to Oct.2021, patients who were indicated of radical cystectomy (RC) but refused were enrolled to TMT treatment prospectively. Inclusive criteria were: ① the patients refused radical surgery; ② male or female, no older than 80 years; ③ no matter the tumor size, the bladder tumor be completely resected by transurethral surgery, and the hydronephrosis be improved after resecting the tumor; ④ the postoperative pathology of urothelial carcinoma; ⑤ recurrent T 1 and high-grade non-muscle invasive bladder cancer (NMIBC) or T 2-4a muscle invasive bladder cancer (MIBC); ⑥ no definitive metastasis in preoperative chest, abdominal CT or MRI; ⑦ hemoglobin ≥100 g/L, white blood cell count ≥4×10 9/L, platelet count ≥100×10 9/L, and normal liver and renal function. The exclusion criteria were: ① tumor invading bladder neck or anterior or posterior urethra; ② bladder contracture or severe urethral stricture; ③ regional lymph node metastasis or distant metastasis by imaging examination; ④ no improvement of hydronephrosis after resection; ⑤ definitive contraindications of radiotherapy or chemotherapy; ⑥ uncontrolled hypertension, diabetes, coronary heart disease or other severe diseases. After cTURBT, paclitaxel (50 mg/m 2 on Day 1 of each week) combined with cisplatin(20 mg/m 2 on day 1-2 of each week)was administered with concurrent radiotherapy (2 Gy/fraction/day) for 4 weeks. If cystoscopy and/or radiographic detected no recurrence or metastasis, the patients were treated with concurrent chemoradiotherapy for 2 and a half weeks (total dose of 64 Gy). The side effects of radiotherapy and chemotherapy during TMT were observed, the quality of life(QOL)was evaluated by FACT-P scale, and the bladder recurrence, distant metastasis and survival were assessed with imaging and cystoscopy. From March 2016 to October 2021, 79 patients with RC were enrolled, including 67 males and 12 females, aged 44-86 years. The pathology of RC was urothelial carcinoma of the bladder. There was no definitive lymph node or distant metastasis in preoperative imaging. The progress and survival after TMT and RC treatment were followed up and the survival rates were calculated by Kaplan-Meier method. Results:Of the 30 patients who underwent TMT, including 25 males and 5 females, aged 32-76 years, there were 7 cases of cT 1 (23.3%), 19 cases (63.3%) of cT 2, 2 cases of cT 3 (6.7%)and 2 cases of cT 4(6.7%), respectively. A total of 132 adverse events of all grades of chemoradiotherapy occurred, of which only 4 were grade Ⅳ, with no bowel leakage or death due to complications. The mean scores of negative questions in FACT-P were 3.22±0.67, 1.30±0.63 and 0.87±0.69 before TMT treatment, 6 and 12 months after TMT treatment, respectively. The quality of life was significantly improved( F=129.081, P<0.001), and the rate of bladder preservation was 86.7%(26/30). Two cases underwent salvage RC(6.7%)and 2 cases died of bladder recurrence(6.7%). There were 8, 4 and 2 patients survived 4, 5 and 6 years, respectively. Seven cases (23.3%) had bladder recurrence, 3 cases (10.0%) underwent distant metastasis and 6 patients (20.0%)died after TMT because of the progression. The 1, 2 and 5 year overall survival rates by TMT treatment were 88.89%, 82.96% and 62.77%, respectively. Median follow-up was 19.5(6.8-44.5) months in the TMT group and 35.5(18.8-53.3) months in the RC group ( z=-1.998, P=0.046). Progression-free survival in the TMT and RC group were 66.7% and 80.0%( χ2=1.047, P=0.306), and the overall survival rates were 80.0% and 80.0% ( χ2=0.482, P=0.488) respectively. The difference was not statistically significant. Conclusions:The TMT is a safe and effective alternative for RC, which can improve the quality of life and control the tumor sufficiently.
