Objective To explore the treatment methods for colorectal cancer patients combined with active tuberculosis. Methods The clinical data of 8 cases of colorectal cancer combined with active tuberculosis from September 2011 to January 2017 in the Affiliated Hospital of Southwest Medical University were analyzed retrospectively. Results All the patients received tumor radical resection after given intensive anti-tuberculotherapy for 2 to 3 weeks. From the second day after surgery, isonicotinyl hydrazide was done through intravenous infusion. When gastrointestinal function was restored, the preoperative anti-tuberculosis treatment was reused. After 2 mouths, consolidation therapy was done. There were 3 cases of complicating pneumonia and 1 case of complicating anastomotic fistula after surgery.Six courses of FOLFOX4 chemotherapy combined with anti-tuberculosis consolidation treatment were carried out for all the patients. No tuberculosis dissemination or death case occurred. Conclusions After given anti-tuberculotherapy for 2 to 3 weeks, the colorectal cancer patients combined with active tuberculosis could receive tumor radical resection. It is safe and feasible to carry out assisted chemotherapy for tumor during the consolidation anti-tuberculotherapy.

Objectives:To investigate the screening status of warning signs for mental and behavioral development (WS) and influencing factors of infants and young children (IYC) in poverty eliminated regions of Henan Province.Methods:This study was a cross-sectional study. A total of 15 680 IYC aged 6-23 months from 51 poverty eliminated counties in Henan province from June to September of 2023 were selected through a multi-stage random sampling method. IYC′s early warning signs were screened using the WS checklist (WSC). Children′s socio-demographic characteristics, maternal information, birth status, and illness conditions such as fever and diarrhea within 2 weeks were measured through a uniformly designed questionnaire. All participants also received the measurement of height, weight, and hemoglobin concentration level. Logistic regression model was used to explore the influencing factors of positive WSC and conducted sensitivity analyses.Results:Among the sample of 15 680 IYC, there were 8 462 boys (53.97%) and 7 218 girls (49.03%), with their age of (15±5) months. A total of 291 (1.86%) IYC were positive in WSC. Parenting risk ( OR=5.07, 95% CI 3.93-6.52, P<0.001) and preterm birth ( OR=1.63, 95% CI 1.06-2.52, P=0.027) were both positively associated with the odds of WSC′s positivity. Being girls ( OR=0.66, 95% CI 0.52-0.85, P=0.001), age (12-17 months, OR=0.47, 95% CI 0.35-0.62, P<0.001; 18-23 months, OR=0.40, 95% CI 0.30-0.54, P<0.001), and maternal educational level (junior high school, OR=0.46, 95% CI 0.32-0.66, P<0.001; senior high school or vocational high school, OR=0.35, 95% CI 0.23-0.56, P<0.001; college and above, OR=0.36, 95% CI 0.23-0.57, P<0.001) were all negatively associated with the risk of WSC′s positivity. Sensitivity analyses demonstrated that, after excluding anemic children, the association between preterm birth and WSC′s positivity was not significant ( OR=1.54, 95% CI 0.95-2.49, P=0.081). Despite this situation, being girls, age and maternal educational level were still negatively associated with the odds of WSC′s positivity (all P<0.05); preterm birth, parenting risk were remained positive associated with the risk of WSC′s positivity (all P<0.05) either by excluding children with protein-energy malnutrition or 2-week morbidity, or using prevalence ratio instead of OR. Conclusions:Among the IYC in poverty eliminated regions of Henan Province, the risk of positivity of WSC was higher for those IYC with parenting risk, preterm birth, boys, younger age, and lower maternal education level. These influencing factors, such as gender, age, preterm birth, parenting risk and maternal educational level, were in certain stability across different IYC characteristics and estimation models.

OBJECTIVE:To investigate the effects of Fluorouracil implants on intraperitoneal chemotherapy safety of advanced gastric cancer patients. METHODS:The information of 264 patients with advanced gastric cancer were analyzed retrospectively. All patients were given Fluorouracil implants 800 mg,scattered into the mesenteric and surgical area,dose of each implantation site less than 200 mg,the distance of implantation range from incision and anastomosis more than 3 cm. All patients were given second generation cephalosporin 30 min before operation,at 3rd h during operation,1-3 d after operation. The occurrence of complications and ADR during hospitalization were observed after operation. RESULTS:After operation,6 patients suffered from complications, with incidence of 2.28%,including 3 cases of gastrointestinal reaction,2 cases of anastomotic bleeding and 1 case of anastomotic leakage. Routine blood test and liver and kidney function were rechecked 3 d after operation,mainly thrombocytopenia and liver function injury,with the incidence of 2.65%. CONCLUSIONS:Fluorouracil implants can be used for intraperitoneal chemotherapy of advanced gastric cancer patients. However,attention should be paid to thrombocytopenia and liver function injury.

Objective: To investigate the relationship among depression, anxiety, stress and addictive substance use behavior in secondary vocational students. Methods: Cluster sampling method and the Adolescent Health-related Behaviors Questionnaire were used to collect demographic characteristics, psychological symptoms, and addictive substance usage among 5 935 students in nine vocational schools in Chongqing, Zhaoqing, Ningbo, and Taiyuan. Multivariate logistic regression analysis was used to analyze the relationship between the addictive substance use behavior and psychological factors. Results: The detection rates of depression, anxiety and stress were 46.5% (n=2 762), 58.7% (n=3 483), and 29.8% (n= 1 770), respectively. The prevalence of addictive substances was 74.8% (n=4 440), traditional drugs was 0.8% (n=50), new drugs was 2.8% (n=166), other addictive drugs was 4.1% (n=241). Multivariate logistic regression analysis showed that compared with the normal psychological states of secondary vocational students, the OR value of mild depression tendency alcohol and tobacco use behavior of secondary vocational students was 1.45; the OR values of mild anxiety, moderate anxiety, severe anxiety and very serious anxiety were 1.46, 1.46, 1.71, and 1.83, respectively; the traditional drugs use behaviors were 5.51, and 2.61, respectively, for the severe anxiety and very serious anxiety. Compared with the normal psychological state of secondary vocational students, the OR values of the severe anxiety and very severe anxiety were 2.56, and 2.66, respectively, for severe anxiety and very serious anxiety. Compared with normal psychological status of secondary vocational students, the OR values of mild, moderate, severe, and very severe anxiety were 2.14, 2.47, 2.39, and 3.45, respectively; all P values <0.05. Conclusion Anxiety and mild depression were risk factors of tobacco and alcohol use in secondary vocational students; severe and above anxiety were the risk factors of drug use in secondary vocational students; anxiety was the risk factor for other addictive drug use in secondary vocational students.

Objective To explore the application of carbon nanoparticles for tracing sentinel node(SN) in early gastric cancer (EGC).Methods Forty-six patients with EGC conducted subserous injection of carbon nanoparticle solution 1.0 mL at 4-6 points around tumor during operation.SN was examined by adopting 3 different methods.The first stained lymph node was defined as the first SN(FSN),and the whole group lymph nodes were identified as the group SN(GSN) and all lymph nodes colored within 5 min were labeled as the all SN(ASN).The affirmative SN and other resected lymph nodes were performed the histopathological examination and comparison.Resnlts In all 46 cases,SN was successfully detected out with the detection rate of 100％;the number of SN,GSN and ASN were 1.04 ± 0.21,3.93-±-1.90 and 13.61 ± 4.36 respectively,the difference in SN number among 3 different methods had statistical significance(P＜0.05).The accuracy rates of FSN,GSN and ASN for judging perigastric lymph node metastasis status were 95.65％,100％ and 100％,respectively.Conclusion The carbon nanoparticles tracing SN in EGC has higher staining rate and higher accuracy for predicting lymph node metastasis;GSN has high accuracy,moreover has less trauma and is most suitable method for detecting SN.

【Objective】 To investigate the influence of knowledge popularization concerning blood donation and blood use on the knowledge, attitudes and practice(KAP) of voluntary blood donation of patients′ families. 【Methods】 Knowledge popularization on voluntary blood donation and clinical blood use was conducted to family members of tumor patients. A questionnaire was designed according to KAP theory to capture the general situation, blood donation history and demographic characteristics of patients′ family members, their knowledge on blood donation and clinical blood use, as well as their intention, attitude and behavior changes on voluntary blood donation before and after popularization. 【Results】 13.49%(104/771) of the family members of tumor patients donated, and most of them aged 28~37 years old(19.7%, 26/132). The awareness rate of patients′ family members on voluntary blood donation and clinical blood use after popularizing was significantly increased as compared with before(P<0.05). Especially, the awareness rate of "blood transfusion significance and the risk of infectious diseases", and " patients were given priority to use blood if their family members donated blood" increased to 61.35%(473/771) and 68.74%(530/771), respectively.Their intention, attitude and behavior of blood donation also changed significantly(P<0.05). The intention of supporting voluntary blood donation increased to 78.21%(603/771), and non-supporting decreased to 4.15%(32/771). Such three behaviors led to a donation rate higher than 70% as donating for charity and sense of responsibility(74.06%, 571/771), donating blood after reassuring(70.69%, 545/771), and promoting their family members′ priority in blood use(71.47%, 551/771). 【Conclusion】 The popularization of knowledge concerning blood donation and blood use can change the intention and attitude of patients′ family members towards voluntary blood donation and further effectively promote their donation behavior.

The typical hallmark of tumor evolution is metabolic dysregulation. In addition to secreting immunoregulatory metabolites, tumor cells and various immune cells display different metabolic pathways and plasticity. Harnessing the metabolic differences to reduce the tumor and immunosuppressive cells while enhancing the activity of positive immunoregulatory cells is a promising strategy. We develop a nanoplatform (CLCeMOF) based on cerium metal-organic framework (CeMOF) by lactate oxidase (LOX) modification and glutaminase inhibitor (CB839) loading. The cascade catalytic reactions induced by CLCeMOF generate reactive oxygen species "storm" to elicit immune responses. Meanwhile, LOX-mediated metabolite lactate exhaustion relieves the immunosuppressive tumor microenvironment, preparing the ground for intracellular regulation. Most noticeably, the immunometabolic checkpoint blockade therapy, as a result of glutamine antagonism, is exploited for overall cell mobilization. It is found that CLCeMOF inhibited glutamine metabolism-dependent cells (tumor cells, immunosuppressive cells, etc.), increased infiltration of dendritic cells, and especially reprogrammed CD8⁺ T lymphocytes with considerable metabolic flexibility toward a highly activated, long-lived, and memory-like phenotype. Such an idea intervenes both metabolite (lactate) and cellular metabolic pathway, which essentially alters overall cell fates toward the desired situation. Collectively, the metabolic intervention strategy is bound to break the evolutionary adaptability of tumors for reinforced immunotherapy.
