Objective To study the spatial distribution of the incidence of pulmonary tuberculosis in Hubei Province and its influencing factors, so as to improve the theoretical basis for scientific development of tuberculosis prevention and control measures in the future. Methods The data of reported incidence of tuberculosis and related influencing factors in various counties and districts of Hubei Province in 2020 were collected. Global Moran's I index, hotspot analysis and geographically weighted regression (GWR) model analysis were used to calculate the spatial autocorrelation of the incidence of tuberculosis, and to analyze the influencing factors affecting the incidence rate of tuberculosis. Results There were obvious regional differences in the space distribution of the incidence rate of tuberculosis. Hot spot analysis showed positive spatial correlation and obvious clustering. The GWR model (AICc=784.251) in this study had higher AICc value compared to the ordinary least squares regression (OLS) model (AICc=804.2585). The GWR model showed that the increase in the proportion of the population aged 65 and above and the proportion of the ethnic minority population had a significant promoting effect on the increase of the incidence rate of tuberculosis, and there was significant spatial heterogeneity. The effect of PM_2.5 concentration on the incidence rate of pulmonary tuberculosis varied in different regions, and the degree of effect was also different. Conclusion The proportion of people aged 65 and above and the proportion of ethnic minorities may significantly influence the incidence of pulmonary tuberculosis. The effect of PM_2.5 concentration varies in different regions, so targeted measures should be formulated according to the situation in different regions.

Background::Adamantinomatous craniopharyngioma (ACP) is the commonest pediatric sellar tumor. No effective drug is available and interpatient heterogeneity is prominent. This study aimed to identify distinct molecular subgroups of ACP based on the multi-omics profiles, imaging findings, and histological features, in order to predict the response to anti-inflammatory treatment and immunotherapies.Methods::Totally 142 Chinese cases diagnosed with craniopharyngiomas were profiled, including 119 ACPs and 23 papillary craniopharyngiomas. Whole-exome sequencing (151 tumors, including recurrent ones), RNA sequencing (84 tumors), and DNA methylome profiling (95 tumors) were performed. Consensus clustering and non-negative matrix factorization were used for subgrouping, and Cox regression were utilized for prognostic evaluation, respectively.Results::Three distinct molecular subgroups were identified: WNT, ImA, and ImB. The WNT subgroup showed higher Wnt/β-catenin pathway activity, with a greater number of epithelial cells and more predominantly solid tumors. The ImA and ImB subgroups had activated inflammatory and interferon response pathways, with enhanced immune cell infiltration and more predominantly cystic tumors. Mitogen-activated protein kinases (MEK/MAPK) signaling was activated only in ImA samples, while IL-6 and epithelial-mesenchymal transition biomarkers were highly expressed in the ImB group, mostly consisting of children. The degree of astrogliosis was significantly elevated in the ImA group, with severe finger-like protrusions at the invasive front of the tumor. The molecular subgrouping was an independent prognostic factor, with the WNT group having longer event-free survival than ImB (Cox, P = 0.04). ImA/ImB cases were more likely to respond to immune checkpoint blockade (ICB) therapy than the WNT group ( P <0.01). In the preliminary screening of subtyping markers, CD38 was significantly downregulated in WNT compared with ImA and ImB ( P = 0.01). Conclusions::ACP comprises three molecular subtypes with distinct imaging and histological features. The prognosis of the WNT type is better than that of the ImB group, which is more likely to benefit from the ICB treatment.

Objective To assess causal associations between specific gut microbiota and different types of cancer by using the two-sample Mendelian randomization(MR)analysis method.Methods On the basis of summary statistics of gut microbiota from a genome-wide association study(GWAS)conducted in German population(n=8956),single nucleotide polymorphisms(SNPs)that were significantly associated with 430 gut microbiota features were extracted as instrumental variables(Ⅳs).Summary statistics from the GWAS of 17 types of cancer were used as outcomes.Two-sample MR analysis was used to explore the causal relationship between gut microbiota and pan-cancer,where the analysis results were dominated by inverse variance weighting.Meanwhile,sensitivity analyse of heterogeneity and horizontal pleiotropy test were done to keep the stability of results.Results The genetic susceptibility of 17 gut microbiota features was causally associated with the occurrence and development of 11 different types of cancer,respectively.Conclusion By exploring the causal relationship between different gut microbiota features and pan-cancer,this study has found a potential causal relationship between specific gut microbiota features and cancer,and these gut microbiota may become new biomarkers to provide new ideas for cancer prevention,early screening,and treatment.

Objective:To explore the caregiving feelings and needs of caregivers of children with β-thalassemia major.Methods:A semi-structured interview was conducted with 14 caregivers of children with β-thalassemia major who were treated at the Affiliated Hospital of Youjiang Medical University for Nationalities from December 2022 to March 2023, and the data were analyzed using the Colaizzi 7-step analysis method.Results:Caregivers of children with β-thalassemia major felt a greater burden of care, including declining physical and mental health, disruption of daily life rhythms and heavy financial burden. And their caregiving needs included psychological and emotional support, guidance on the physical and mental health of children, assurance of a stable blood supply and medical and social support.Conclusions:Caregivers of children with β-thalassemia major have a heavy burden of care and face various nursing difficulties in the daily care of children. Medical staff should actively take measures to meet their care needs and improve their care quality and quality of life.

Artificial intelligence is the use of computer algorithms to copy or simulate human behavior, giving machines human-like ability. With the rapid development of radiotherapy technology, artificial intelligence has great potential value in all stages of radiotherapy. Image segmentation is the premise of target delineation using artificial intelligence. The commonly used methods in clinic mainly include automatic segmentation based on deep learning and atlas library. The technology of artificial intelligence in organs at risk delineation is relatively mature, which can significantly shorten the delineation time and improve the efficiency. The delineation of tumor targets has achieved some success, the accuracy still needs to be further improved. Artificial intelligence technology makes the target delineation more and more efficient, and the consistency and repeatability have been significantly improved. It is expected to provide more accurate and individualized treatment for patients.

Objective:To investigate the 2 years’ efficacy of intravesical instillation of domestic BCG versus epirubicin in the prevention of recurrence of intermediate-risk or high-risk non-muscular invasive bladder cancer and predictive factors of BCG instillation.Methods:From July 2015 to June 2020, 18-75 years old patients with moderate to high-risk non muscle invasive bladder cancer (NMIBC) confirmed by pathological examination were involved. The ECOG score was 0-2. Exclusion criteria included ①immune deficiency or impairment (such as AIDS), using immunosuppressive drugs or radiotherapy, suspected allergic to BCG or epirubicin or excipients of the two drugs, fever or acute infectious diseases including active tuberculosis or receiving anti tuberculosis treatment, with severe chronic cardiovascular and cerebrovascular diseases or chronic kidney disease; ②combined with other urogenital system tumors or other organ tumors; ③combined with muscle invasive bladder urothelial carcinoma (≥T 2); ④undergoing chemotherapy, radiotherapy or immunotherapy within 4 weeks (immediate instillation after surgery not included); ⑤ pregnant or lactating women; ⑥ comfirmed or suspected bladder perforation; ⑦gross hematuria; ⑧cystitis with severe bladder irritation that may affect the evaluation; ⑨participat in other clinical trials within 3 months; ⑩alcohol or drug addiction; ?any risk factors that may increasing the risk of patients. Epirubicin 50 mg was irrigated immediately after the operation(TURBT or laser resection). The patients were randomly divided into BCG15 group, BCG19 group and epirubicin group by the ratio of 2∶2∶1, and the patients were maintained intravescical instillation for 1 year. The recurrence and adverse events of the three groups were compared. Univariate and multivariate analysis was performed to predict the risk factors of BCG irrigated therapy failure. Result:By June 15, 2020, the median follow-up duration was 22.1 months(12.1, 32.3), and there was no statistical difference between the groups ( P=0.9024). There were 274 patients enrolled in BCG19 group, 277 patients enrolled in BCG15 group and 130 patients enrolled in the epirubicin group. The drop-off rate was 16.6%(113 cases)and made no difference between groups( P=0.6222). There were no significant difference in age, gender, BMI, or ECOG score( P>0.05). During the follow-up, 116 cases was detected recurrence or progression. The recurrence rate of the three groups was 14.2% and 14.8% in BCG19 group and BCG15 group, and 27.7% in the epirubicin group. There was no difference in recurrence rate between BCG19 and BCG15 group( P=0.9464). The recurrence rate of BCG19 group was lower than that of the epirubicin group ( P=0.0017). The recurrence rate of BCG15 group was lower than that of the epirubicin group ( P=0.0020). There was no difference in the cumulative recurrence free survival rate between BCG19 and BCG15 group (95% CI0.57-1.46, P=0.7173). The cumulative recurrence free survival rate of BCG 19 group was better than that of the epirubicin group( HR=0.439, 95% CI0.26-0.74, P=0.0006), and the cumulative recurrence free survival rate of BCG15 group was better than that of the epirubicin group ( HR=0.448, 95% CI0.29-0.80, P=0.0021). The total incidence of adverse events in 19 BCG19, BCG15 and epirubicin group were 74.5%, 72.6% and 69.8% respectively. There was no difference in the incidence of adverse events between BCG19 and BCG15 group( P=0.6153). The incidence of adverse events in epirubicin group was lower than that of BCG19( P=0.0051) and BCG15( P=0.0167) groups.There was no significant difference in the incidence of serious adverse events (SAE) among the three groups ( P=0.5064). Log rank test univariate analysis and Cox risk regression model multivariate analysis showed that the history of bladder cancer recurrence( HR=6.397, 95% CI1.95-20.94, P=0.0001)was independent risk factor for BCG irrigation failure. Conclusions:The 2 years’ efficacy of intravesical instillation of domestic BCG is better than than of epirubicin with good tolerance and safety. There is no difference between BCG19 and BCG15 group. BCG doesn’t increase SAE compared with epirubicin. Recurrence status was an independent prognostic factor regarding recurrence-free survival.

Objective To investigate the efficacy and safety of intravesical instillation of BCG vaccine in the prevention of early recurrence of middle and high risk non-muscle invasive bladder cancer.Methods From July 2015,patients with non-muscle invasive bladder cancer aged 18-75 years with informed consent were screened and underwent transurethral resection of bladder tumor (TURBT).Immediately intravesical instillation of epirubicin 50 mg was given postoperatively.After pathology was comfirmed,patients was enrolled in group 1 (BCG15) or group 2 (BCG 19) or the control group (epirubicin 18) randomly with SAS 9.3 software.Data of follow-up and Adverse event was collected and analyzed.Results By May 31,2019,531 patients were enrolled in the study.The drop-off rate was 20.1％.167 patients (143 males and 24 females)in group 1,172 patients (141 males and 31 females)in group2 and 84(75 males and 9 females) in the control group with follow-up data were analyzed.There were no significant differences in age,gender,BMI,ECOG score,risk stratification between the three groups (P =0.8641,P =0.2906,P =0.9384,P =0.6126).The median follow-up time makes no statistical difference between the groups (P =0.9251),12.0 (6.0,22.5) months,13.0 (6.0,22.3) months,and 13.0 (7.0,22.3) months.The median recurrence time of the three groups was 4.0 (3.0,6.0) months,4.5 (3.0,9.8) months,4.5 (3.0,8.8) months.There was no statistical difference between the three groups (P =0.2852).Risk stratification in the patients got no significant difference between the three groups (P ＞ 0.05).The 1-year recurrence-free survival rates were 80.0％ in the group 1 and 88.3％ in the group 2 and 73.7％ in the control group.The group 2 was superior to the group 1 and the control group (P =0.0281,P =0.0031).There was no significant difference between group 1 and control group (P =0.2951).There was no significant difference in the cumulative recurrence-free survival between the experimental group 1 and the experimental group 2,(95％ CI 0.80-2.43,P =0.2433).The cumulative recurrence-free survival in the group 1 and the group 2 was better than the control group (95 ％ CI 0.31-0.92,P =0.0266;95 ％ CI 0.20-0.65,P =0.0008).All the cases underwent instillation were analyzed for adverse events.The incidence of overall AE(adverse events) in group 1 was 68.5％ (152/222),the incidence of grade Ⅰ-Ⅱ AE was 53.2％ (118/222),the incidence of grade Ⅲ-Ⅳ AE was 15.3％ (32/222).The incidence of overall AE in the group 2 was 71.8％ (160/223),the incidence of grade Ⅰ-Ⅱ AE was 60.1％ (134/223),and the incidence of grade Ⅲ-Ⅳ AE was 11.7％ (26/223).The overall AE rate in the control group was 53.2％ (59/111),of which the incidence of grade Ⅰ-Ⅱ AE was 42.4％ (47/111),and the incidence of grade Ⅲ-Ⅳ AE was 10.8％ (12/111).There was no difference in the incidence of overall AE between the group 1 and the group 2 (P =0.4497).The incidence of AE in the two experimental groups was higher than that in the control group (P =0.0062,P =0.0008).There was no difference in the incidence of grade Ⅲ-Ⅳ AE between the three groups (P =0.3902).Conclusions BCG(19 instillation schedule) has a better effect on preventing recurrence after 1 year of bladder surgery,which is superior to epirubicin group.The long-term efficacy of BCG in preventing recurrence and the efficacy of different schedules need to be further followed up.The lower urinary tract symptoms,which are mainly urinary frequency,are one of the causes of case fallout and should be fouced in future.Compared with epirubicin,BCG perfusion does not increase the incidence of grade Ⅲ-Ⅳ adverse reactions,and is safe to use.
