Objective To compare the clinical efficacy of neuroendoscope-assisted evacuation and navigation-assisted puncture drainage in treating thalamic hemorrhage breaking into the ventricle. Methods A retrospective analysis was conducted on the clinical data of 93 patients with thalamic hemorrhage breaking into the ventricle at Taihe Hospital of Wannan Medical College between January 2022 and February 2024. The patients received neuroendoscope-assisted removal of thalamic hematoma combined with contralateral extraventricular drainage (n＝44, neuroendoscope group) and navigation-assisted thalamic hematoma puncture drainage combined with contralateral extraventricular drainage (n＝49, navigation group), respectively. The treatment efficacy, surgical situation, and prognosis between the two groups were compared. Results The neuroendoscope group had longer operation duration, more intraoperative blood loss, higher hospitalization costs than the navigation group (P＜0.05). The neuroendoscope group had higher hematoma clearance rate 3rd after surgery and shorter length of stay than the navigation group (P＜0.05). There was no significant difference in the incidence of intracranial infection after surgery between the two groups. The neuroendoscope group had higher Glasgow coma scale (GCS) score at 1 week after surgery and Glasgow outcome scale (GOS) score at 3 months after surgery (P＜0.01). Conclusions Compared with navigation-assisted puncture, neuroendoscope-assisted evacuation can improve the thalamic hemorrhage clearance rate, shorten the length of stay, and improve the prognosis of patients.

The theory of constitution in traditional Chinese medicine （TCM） has emerged as a new discipline in recent years. Constitution plays a vital role in the onset，progression，transformation，and prognosis of diseases. At present，some clinical scholars have adopted a novel diagnostic and treatment model of "constitution differentiation-disease identification-syndrome differentiation"，in which constitution is regarded as a core element throughout the diagnostic and therapeutic process. Constitution is closely associated with etiology，onset，pathogenesis，syndrome differentiation，and treatment. Against this background，the construction of animal models based on constitution holds far-reaching significance for advancing clinical research. This paper focuses on the construction and evaluation of rodent models with Qi-deficiency constitution，aiming to explore how to further induce Qi-deficiency syndromes and related disease states on the basis of Qi-deficiency constitution models，thereby developing an integrated animal model that embodies the trinity of "constitution-disease-syndrome". The establishment of this model not only provides a solid experimental foundation for the development of new therapies and drugs in TCM targeting specific constitutions，diseases，and syndromes，but also greatly promotes the modernization and scientific advancement of TCM theory. By comprehensively applying multidisciplinary technologies and methods，the study evaluates the model's validity，reliability，and practicality，with the aim of opening new avenues for future research in TCM and promoting the development of the field.

[Purpose]To analyze the incidence trend and age,period,cohort effects of brain and other central nervous system tumors(brain tumor)in Qidong City of Jiangsu Province from 1972 to 2021.[Methods]The incidence data of brain tumor from 1972 to 2021 were collected from the Qidong cancer registry database.The crude incidence rate(CR),age-standardized rate by Chi-nese standard population(ASRC),age-standardized rate by world standard population(ASRW)and average annual percentage change(AAPC)were calculated.The age-period-cohort(APC)model was used to analyze the age,period,and cohort effects of brain tumor incidence in Qidong City from 1972 to 2021.[Results]A total of 2 801 cases of brain tumor occurred in Qidong City from 1972 to 2021,including 1 475 male cases and 1 326 female cases.From 1972-1976 to 2017-2021,the CR increased from 1.81/10 5 to 9.28/10 5,the ASRC increased from 2.07/10 5 to 4.96/10 5,and ASRW increased from 2.00/105 to 4.98/105.From 1972 to 2021 the AAPC of CR,ASRC and ASRW were 3.97％(3.53％for male and 4.37％for female),2.02％(1.66％for male and 2.24％for female)and 2.06％(1.63％for male and 2.24％for female)(all P＜0.001).The Wald's Chi-square test of the APC model showed that there were significant differences in the trends of age,period and birth cohort effect of brain tumor risk(all P＜0.05).The age effect showed that the incidence of brain tumor increased with age,starting from the age group of 45～49 years old and reaching a peak of 25.84/10 5 in age group of 75～79 years old(95％CI:21.17/10 5～31.53/10 5).The period ef-fect showed that the risk of recent period was higher than that in the early period using 1992-1996 period as the reference,reaching the highest in 2012-2016(RR=1.64,95％CI:1.38～1.95).The birth cohort effect showed that the highest risk was in 2017-2021 births cohort(RR=11.17,95％CI:4.26～29.26)using 1952-1956 birth cohort as the reference.[Conclusion]The incidence of brain tumor in Qidong City has been rising;and age,period and cohort are the main influencing factors,suggesting that the middle-aged and elderly population should be the focus of brain tumor prevention and control.

Objective:To analyze the incidence trends of malignant tumors in the elderly population aged over 60 years in Qidong City from 1972 to 2021, as well as to predict the incidence rate for the next decade.Methods:Data were obtained from the Qidong Cancer Registry and Reporting System.The crude incidence rate(CR), age-standardized incidence rate using the Chinese standard population(ASRC), and age-standardized incidence rate based on Segi's world standard population(ASRW)were calculated.Joinpoint regression analysis was conducted using Joinpoint 4.9.1.0 software to determine the average annual percentage change(AAPC)in incidence.Additionally, the ARIMA model implemented in SAS 9.2 software was utilized for time series analysis to forecast incidence trends over the forthcoming 10 years.Results:In Qidong City, a total of 87, 401 malignant tumors were reported in the elderly population.The ASRW increased from 736.85 per 100, 000 in the years 1972-1976 to 1 056.33 per 100, 000 in 2017-2021.Specifically, the ASRW for males rose from 968.56 per 100, 000 to 1 332.75 per 100, 000, while the ASRW for females increased from 550.62 per 100, 000 to 825.44 per 100, 000, with AAPC values of 1.16%, 0.94%, and 1.44% over 50 years(all P<0.001).The incidence trend exhibited an upward trajectory with age, peaking in the 75-79 age group.The AAPC values for the incidence rates in the age groups of 60-64, 65-69, 70-74, 75-79, and those aged over 80 were 0.64%, 0.93%, 0.92%, 2.02%, and 2.44%, respectively(all P<0.001).Among the various cancers, lung cancer, which ranked first, saw an increase in ASRW from 100.87 per 100, 000 in 1972-1981 to 248.84 per 100, 000 in 2012-2021.In contrast, gastric cancer, ranked second, decreased from 216.23 per 100, 000 in 1972-1981 to 103.54 per 100, 000 in 2012-2021.Liver cancer, ranked third, fluctuated from 113.47 per 100, 000 in 1972-1981 to 125.13 per 100, 000 in 2012-2021.Colorectal cancer, ranked fourth, increased from 40.06 per 100, 000 in 1972-1981 to 123.47 per 100, 000 in 2012-2021, while esophageal cancer, ranked fifth, decreased from 63.42 per 100, 000 in 1972-1981 to 28.65 per 100, 000 in 2012-2021.The AAPC values over 50 years for these cancers were 2.25%, -1.89%, 0.36%, 3.13%, and -1.86%, respectively(all P<0.05).Projections indicate that by 2031, the incidence of malignant tumors among the elderly population in Qidong will reach 1 253.84 per 100, 000, with estimates of 1 566.67 per 100, 000 for males and 983.14 per 100, 000 for females. Conclusions:The incidence of malignant tumors among the elderly population in Qidong City is increasing.Common types of cancer in this demographic include lung cancer, gastric cancer, liver cancer, colorectal cancer, and esophageal cancer.Notably, lung cancer, liver cancer, and colorectal cancer are on the rise and should be prioritized in cancer prevention and control efforts.

Objective:To identify and validate secreted effector proteins of Chlamydia psittaci ( C. psittaci) through bioinformatic prediction and experimental verification, and to characterize their subcellular localization in host cells. Methods:Potential effector proteins were predicted using bioinformatics tools. Candidate effectors were fused to β-lactamase through the constructed expression vectors, and these vectors were transformed into C. psittaci. The secretion of these candidate effectors was evaluated by β-lactamase translocation assays. Eukaryotic expression vectors of confirmed effectors were transfected into host cells to determine their intracellular localization patterns. Results:Bioinformatic analysis identified 29 candidate effector proteins. Experimental validation confirmed the secretion of five effectors, with four exhibiting cytoplasmic localization and one displaying nuclear localization in host cells.Conclusion:This study characterizes five novel C. psittaci secreted effector proteins, providing critical insights for investigating the molecular pathogenesis of psittacosis.

Objective:To determine the incidence of acute focal bacterial nephritis (AFBN) in children with febrile urinary tract infections (UTI) and to identify associated risk factors.Methods:A retrospective cohort study included 181 children hospitalized with febrile UTI at Fujian Children′s Hospital from April 2021 to September 2023. Demographic data, clinical manifestations, and laboratory findings were collected. Patients were categorized into AFBN group and non-AFBN group based on AFBN diagnosis. The incidence of AFBN within this febrile UTI cohort was determined. The diagnostic value for pre-antibiotic blood white blood cell (WBC) count and C-reactive protein (CRP) level, along with post-treatment fever duration and pyuria duration for AFBN was evaluated using the area under curve (AUC) of the receiver operating characteristic (ROC).Results:The cohort comprised 181 children with febrile UTI (100 boys and 81 girls), age of 0.6 (0.3, 1.0) years. Eleven patients (6.1%) were diagnosed with AFBN. For predicting AFBN, the AUC was 0.71 (95% CI 0.55-0.85, P=0.026) for pre-antibiotic WBC count and 0.80 (95% CI 0.71-0.90, P=0.001) for pre-antibiotic CRP level, with optimal cutoff values of 16.0×10 9/L and 80.1 mg/L, respectively. For post-treatment parameters, the AUC was 0.79 (95% CI 0.69-0.92, P=0.001) for fever duration and 0.84 (95% CI 0.72-0.97, P<0.001) for pyuria duration, with optimal cutoff values of 1.9 d and 5.5 d, respectively. The combination of pre-antibiotic WBC count >16.0×10 9/L and CRP>80.1 mg/L yielded a sensitivity of 0.73 and a specificity of 0.86 for AFBN prediction. Similarly, the combination of post-treatment fever duration ≥2 d and pyuria duration >5 d demonstrated a sensitivity of 0.82 and specificity of 0.88. Conclusions:AFBN incidence was 6.1% in this cohort of children with febrile UTI. AFBN should be highly suspected in febrile UTI children presenting with either a pre-antibiotic WBC count >16.0×10 9/L and CRP >80.1 mg/L, or a post-treatment fever duration ≥2 d and pyuria duration >5 d.

Objective:To explore the surgical strategies and clinical efficacy of open partial nephrectomy in the treatment of renal angiomyolipoma (AML) with inferior vena cava tumor thrombus.Methods:A retrospective analysis was conducted on the clinical data of 5 patients with renal AML and inferior vena cava tumor thrombus who underwent partial nephrectomy at Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine from October 2014 to December 2022. There were 2 male and 3 female patients, with a median age of 37 years, ranged from 33 to 45 years. All patients were identified during routine physical examinations. Four patients presented with right-sided lesions, while one had a left-sided lesion. The diameter of the primary tumor within the kidney ranged from 3.0 to 7.0 cm, with a median diameter of 5.5 cm.The length of the tumor thrombus within the inferior vena cava ranged from 1.0 to 6.0 cm, with a median length of 1.5 cm. Among them, 2 patients underwent laparoscopic nephrectomy combined with extracorporeal workbench tumor resection and autologous kidney transplantation (the workbench surgery group), while 3 patients underwent open in-situ partial nephrectomy combined with removal of inferior vena cava tumor thrombus (the in-situ nephron-sparing surgery group). The surgical method of the workbench surgery group: The patients first underwent laparoscopic nephrectomy on the affected side combined with inferior vena cava tumor thrombus removal, then the incision was extended to remove the affected kidney, and table partial nephrectomy was performed. After completely removing the tumor and tumor thrombus within the affected kidney and renal vein, autologous kidney transplantation was performed in the iliac fossa. The surgical method of the in-situ kidney preservation surgery group: The affected kidney, renal artery and vein on the affected side, inferior vena cava, and contralateral renal vein were dissected and exposed. The distal end of the inferior vena cava, the contralateral renal vein, the proximal end of the inferior vena cava, and the renal artery on the affected side were blocked respectively. The venous wall was opened in the middle of the renal vein, and the tumor thrombus was gradually pulled out. According to the pre-marked tumor boundary, the tumor within the kidney was gradually removed by alternate blunt and sharp dissection combined with suction, and the wound surface was sutured layer by layer. The perioperative conditions, complications, and follow-up results of the patients were analyzed.Results:All 5 surgeries were successfully completed, with a median operation time of 100 to 450 minutes and a median operation time of 200 minutes. The intraoperative bleeding volume was 100 to 600 ml, with the median of 150 ml. In the in-situ nephron-sparing surgery group, the renal artery occlusion time was 28 to 41 minutes, and the median occlusion time was 34 minutes. All patients were discharged safely after surgery, and there were no serious perioperative complications. The postoperative pathology of all 5 patients was renal angiomyolipoma, without any epithelioid components. The patients were followed up for 12 to 90 months, with a median follow-up duration of 24 months. None of the 5 patients had tumor recurrence or metastasis, and no patient developed chronic kidney dysfunction during follow-ups.Conclusions:Renal AML with venous tumor thrombus is a challenging clinical problem. In situ open partial nephrectomy or the combined approach through the workbench and autologous kidney transplantation can effectively remove the tumor thrombus and maximize the protection of renal function. For cases of ① multiple or complex renal AML; ② complex vascular system structure within the renal sinus requiring precise anatomy; ③ renal AML with a previous history of hemorrhage, complex adhesions around, and difficult dissociation, table partial nephrectomy combined with inferior vena cava tumor thrombus removal and autologous kidney transplantation can be selected. For cases where the expected surgical operation is simple, in situ open partial nephrectomy can significantly shorten the operation time and reduce surgical trauma.

Objective To investigate the effectiveness and safety of drug-eluting beads bronchial arterial chemoembolization(DEB-BACE)versus BACE for the treatment of stage Ⅲ-Ⅳ lung squamous cell carcinoma.Methods A total of 104 patients with stage Ⅲ-Ⅳ lung squamous cell carcinoma,who were admitted to the Lishui Municipal Central Hospital of China between January 2013 and August 2021,were enrolled in this study.According to the therapeutic scheme,the patients were divided into DEB-BACE group(n=41)and BACE group(n=63).For patients of DEB-BACE group,Cisplatin at 75 mg/m2 dose and gemcitabine at 1 000 mg/m2 dose(400 mg was used as loaded-drug dose)were injected through a microcatheter,which was followed by embolization with CalliSpheres microspheres loaded with 400 mg of gemcitabine.For patients of BACE group,Cisplatin at 75 mg/m2 and gemcitabatin at 1 000 mg/m2 were injected through a microcatheter,which was followed by arterial embolization with blank microspheres.Three weeks after DEB-BACE or BACE,the patients of both groups were started on intravenous chemotherapy.The primary study endpoint was overall survival(OS).The secondary study endpoints included progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),adverse reactions,and the remission rate of dyspnea.Results Of the 104 patients,63 received BACE sequential intravenous chemotherapy and 41 received DEB-BACE sequential intravenous chemotherapy.The median OS in DEB-BACE group was 23.0 moths,which was obviously longer than 12.0 months in BACE group(P=0.009).Multivariate Cox regression analysis showed that DEB-BACE treatment was an independent risk factor for OS(HR=0.59,95％ CI:0.38-0.91,Log-rank test P=0.018).Meanwhile,the remission rate of dyspnea in DEB-BACE group was significantly higher than that in BACE group(57.1％ vs 30.6％,P＜0.043).Conclusion Compared with BACE sequential intravenous chemotherapy,DEB-BACE sequential intravenous chemotherapy can significantly prolong the survival time of patients with stage Ⅲ-Ⅳ lung squamous cell carcinoma and significantly improve the symptoms of dyspnea,which has important applications in the treatment of patients with advanced lung squamous cell carcinoma.

Objective:To analyze the trend of ovarian cancer incidence in Qidong City from 1972 to 2021 and evaluate the age, period, and cohort effect.Methods:The ovarian cancer incidence data from 1972 to 2021 were extracted from the Qidong Cancer Registry Database, the crude incidence rate (CR), age standardized rate by Chinese population (ASR-C), age standardized rate by world population (ASR-W), and average annual percent change (AAPC) were calculated. The age-period-cohort model was used to analyze the age, period, and birth cohort effects of the ovarian cancer incidence in Qidong from 1972 to 2021.Results:From 1972 to 2021, a total of 1 007 cases of ovarian cancer occurred in Qidong. The AAPC values of CR, ASR-C, and ASR-W were 7.02% , 5.17%, and 5.12% , respectively (all P＜0.001). The time trends showed that, the AAPC values of the age groups of 0-34, 35-44, 45-54, 55-64, 65-74, and over 75 years old were 4.10%, 4.74%, 6.02%, 4.86%, 4.23%, and 5.18%, respectively (all P＜0.05). The age effect showed that the incidence rate of ovarian cancer increased obviously from the 45-49 year-old group, reaching a peak of 20.67/100 000 in the 75-79 year-old group. Compared with the 1992-1996 group, the period of 2002-2021 had significant effects on the incidence rise of ovarian cancer (all P＜0.05), and the incidence rate ratio ( RR) increased with the period: in 2017-2021 the RR was 3.86 (95% CI: 2.72-5.47). Using births from 1952 to 1956 as the reference group, the RR increased slowly from 0.12 (95% CI: 0.02-0.91) in 1892-1896, and peaked in 2007-2011 with an RR of 18.05 (95% CI: 3.51-92.87). The birth cohorts in 1967-2011 had significant effects on the incidence rise of ovarian cancer (all P＜0.05). The Waldχ 2 test of the age-period-cohort model showed that there were significant differences in the age, period, and birth cohort effects (all P＜0.001). Conclusions:The incidence of ovarian cancer in Qidong was on the rise. Age, period, and cohort were the main factors affecting the incidence of ovarian cancer. The middle-aged and elderly women were the focus of ovarian cancer prevention and control.
