Objective To explore the association of diabetes status with the development of tuberculosis (TB) among the community population in Shanghai, and to provide evidence for the formulation of tuberculosis prevention and control strategies. Methods This population-based cohort study was based on Shanghai Suburban Adult Cohort and Biobank (SSACB) in China. The baseline data were acquired by questionnaires, physical examinations and blood biochemistry tests. TB incidence was obtained by matching with TB management information system data. A Cox proportional risk model was established to assess the risk of tuberculosis. Results A total of 36 014 research subjects were included, with an average age of 56.3±11.3 years, of which 14 587 (40.5%) were male. Over 6 years of follow-up, 47 individuals progressed to tuberculosis (incidence rate: 19.8 per 100 000 person-year, 95% CI: 14.6 -26.4). An increased risk of TB was observed in participants with newly diagnosed diabetes compared with those without diabetes (adjusted hazard ratio [aHR], 2.73; 95% CI, 1.19 - 6.28). Conclusion The risk of tuberculosis in newly diagnosed diabetic patients is significantly increased, and strengthening tuberculosis screening for this population should be considered in practical work.

Objective:To study the immunotherapeutic effect of chimeric hepatitis B core protein virus-like particles in subcutaneous lung adenocarcinoma mouse model, lays the foundation for the progression of tumor nano-therapeutic technology development.Methods:The plasmid was constructed by inserting a B-cell epitope of the human epidermal growth factor receptor-2 (HER-2) at hepatitis B core protein′s major immunodominant region (MIR). The recombinant virus nanoparticle, denoted as HBc-HER2, was obtained by E. coli expression system, followed by a series of purification steps. The immune response to this recombinant protein nanoparticle was assessed by measuring levels of anti-HER-2 antibody levels and characterizing antibody isotypes in a subcutaneous tumor mice model of lung adenocarcinoma. While tumor therapeutic efficacy was evaluated by measuring tumor size changes with an electronic caliper and MRI photography of subcutaneous tumor in mice.Results:A high-purity HBc-HER2 recombinant protein was obtained and could assemble into nanoparticle. Animal studies had demonstrated the robust immunogenicity of this vaccine in inducing high levels of HER-2 specific antibodies, yielding positive therapeutic outcomes against tumors.Conclusions:The engineered HBc-HER2 demonstrated notable tumor therapy efficacy in a subcutaneous lung adenocarcinoma mouse model, offering a foundation for tumor therapeutic nanotechnology vaccine research.

Objective:To explore the development and interaction between chronotype and depressive symp-toms among middle school students in Chongqing.Methods:A total of 1208 middle school students(613 in grade 7,595 in grade 10)were surveyed for three follow-ups at 6-month intervals.Periods T1-T3 represented baseline,6 months later,and 12 months later,respectively.Chronotype and depressive symptoms were measured by the Morn-ing and Evening Questionnaire-5(MEQ-5)and the Patient Health Questionnaire-9(PHQ-9).Analyses were per-formed using SPSS 26.0 and Mplus 8.3.Results:The MEQ-5 scores were lower in T1 than in T3,and the scores were lower in T2 than in T1 and T3(F=20.08,P＜0.001),suggesting a fluctuating trend of chronotype shifting to the Evening-type first after baseline and then to the Morning-type.The PHQ-9 scores exhibited a significant differ-ence among the three-time measurements(x2/df=9.77/2,P＜0.01).But pairwise comparisons did not yield any statistically significant findings(P＞0.05).The cross-lagged panel model showed that pathways of Ti MEQ-5 scores negatively predicted Ti+1 PHQ-9 scores(βTi-Ti+1=-0.12/-0.09,P＜0.05)and TiPHQ-9 scores nega-tively predicted Ti+1 MEQ-5 scores(βTi-Ti+1=-0.07/-0.11,P＜0.05).Conclusion:Chronotype and depressive symptoms show some changes in adolescents.The more inclined adolescents are to the Evening-type,the higher the likelihood of depressive symptoms occurring later.The more severe the depressive symptoms,the greater the likeli-hood of a subsequent shift to the Evening-type.

Objective To construct and apply a management plan for microaspiration of oropharyngeal secretions in ICU intubated patients.Methods Based on evidence summaries and expert consultation,a management plan for microaspiration of oropharyngeal secretions in ICU intubated patients was constructed,consisting of 19 items covering 7 aspects including identification of risk factors,position management,tube and cuff selection,cuff management,mechanical ventilation management,pain and sedation management,removal of oropharyngeal and subglottic secretions,and oral care.Convenience sampling was used to select 141 ICU intubated patients from a tertiary A comprehensive hospital in Suzhou from June,2022 to September,2023.Patients were divided into an experimental group(n=72)and a control group(n=69)according to the wards.The experimental group received the management plan for microaspiration of oropharyngeal secretions in ICU intubated patients.The control group received the nursing bundle for ventilator associated pneumonia(VAP).The incidence and time from intubation to microaspiration and VAP,duration of mechanical ventilation,ICU length of stay,and disease outcome were compared between the 2 groups.Results The incidence of microaspiration of oropharyngeal secretions,the duration of mechanical ventilation,time from intubation to microaspiration showed significant differences between the 2 groups(P<0.05).There were no significant differences in the incidence of ventilator associated pneumonia,ICU length of stay,and disease outcome between the 2 groups(P>0.05).The time from intubation to VAP in the experimental group was 7.5 days,and that in the control group was 3.8 days.Conclusion The application of the management plan for microaspiration of orophaiyngeal secretions in ICU intubated patients is beneficial for reducing the incidence of microaspiration,delaying the time from intubation to microaspiration and VAP,and shortening the duration of mechanical ventilation.

Objective To investigate the effect and mechanism of Di'ao Xinxuekang(hereinafter referred to as Xinxuekang)combined with Simvastatin on atherosclerosis(AS)mice.Methods Eight C57BL/6J mice were used as control group,and 32 ApoE-/-mice were randomly divided into model group,Xinxuekang group(160 mg·kg-1),Simvastatin group(1.3 mg·kg-1)and combined treatment group(Xinxuekang 160 mg·kg-1+Simvastatin 1.3 mg·kg-1),with eight mice in each group.The control group was fed with conventional diet,and the other four groups were fed with high-fat diet.At the same time,each administration group was given intragastric administration according to the above dose,and the volume of intragastric administration was 10 mL·kg-1,once a day for 18 weeks.After administration,the levels of serum total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C)and high density lipoprotein cholesterol(HDL-C)were detected.Oil red O staining was used to observe the formation of aortic plaque and liver lipid accumulation in mice.Serum PCSK9 level was detected by ELISA.The mRNA and protein expression levels of LDLR,HNF1α and SREBP2 in liver tissues were detected by qRT-PCR and Western Blot.Results(1)Compared with the control group,the levels of serum TC,TG and LDL-C in the model group were significantly increased(P＜0.01),and the level of HDL-C was significantly decreased(P＜0.01).The percentage of aortic root plaque area,the percentage of total aortic plaque area and the percentage of liver lipid droplet area were significantly increased(P＜0.01).The mRNA and protein expression levels of LDLR in liver tissue were significantly decreased(P＜0.01),and the serum PCSK9 level was significantly increased(P＜0.01).The mRNA and protein expression levels of HNF1α and SREBP2 in liver tissues were significantly increased(P＜0.05,P＜0.01).(2)Compared with the model group,the levels of serum TC,TG and LDL-C in the Xinxuekang group and the combined treatment group were significantly decreased(P＜0.05,P＜0.01),and the level of HDL-C was significantly increased(P＜0.05).The level of serum LDL-C in Simvastatin group was significantly decreased(P＜0.01).The percentage of aortic root plaque area and the percentage of total aortic plaque area in the Xinxuekang group and the combined treatment group were significantly decreased(P＜0.05,P＜0.01),and the percentage of liver lipid droplet area in each administration group was significantly decreased(P＜0.01).The protein expression level of LDLR in liver tissue of mice in Xinxuekang group and combined treatment group was significantly increased(P＜0.05),the serum PCSK9 level was significantly decreased(P＜0.05,P＜0.01),and the mRNA and protein expression levels of HNF1 α and SREBP2 in liver tissue were significantly decreased(P＜0.05,P＜0.01).(3)Compared with the Simvastatin group,the serum HDL-C level in the combined treatment group was significantly increased(P＜0.05).The percentage of aortic root plaque area and the percentage of liver lipid droplet area were significantly decreased(P＜0.05,P＜0.01).The protein expression level of LDLR in liver tissue was significantly increased(P＜0.01),and the serum PCSK9 level was significantly decreased(P＜0.01).The expression levels of HNF1α protein and SREBP2 mRNA in liver tissues were significantly decreased(P＜0.05,P＜0.01).Conclusion Xinxuekang may play a synergistic effect on lipid-lowering and anti-AS effects of Simvastatin by inhibiting the expressions of SREBP2 and HNF1α and regulating the PCSK9/LDLR signaling pathway.

Objective:To compare the feasibility and safety of a new portable endoscopic system and the conventional endoscopic system for the detection and emergency treatment of abdominal trauma in animal models.Methods:Three healthy Bama pigs, which were fasted and water deprivation for 8 h before surgery and then underwent induction anesthesia. A layer-by-layer incision was made into the abdominal cavity of Bama pigs. An artificial pneumoperitoneum was established using a laparoscopic pneumoperitoneum machine. A bullet model was inserted into the abdominal cavity to build the bullet wound model. After the bullet model was removed, a shrapnel model was inserted into the mid-abdomen to build the shrapnel wound model. The two types of endoscopic system were used to detect, remove bullet model or shrapnel model of the three Bama pigs respectively. The procedure order of the two systems was assigned according to the random number table method. The surgical success, operation time, endoscopy pipeline patency, endoscopic operation satisfaction, adverse events and equipment defects were recorded.Results:Three surgeries were performed using the new portable endoscopic system and three other surgeries using the conventional endoscopic system, all of which were successful. The time of the new portable endoscopic system to find and remove the bullet model, and the shrapnel model were 232.33±11.68 s, 300.33±57.70 s, 170.00±44.44 s and 52.67±2.52 s, respectively. The corresponding time of the conventional endoscopic system were 232.67±21.20 s ( t=-0.054, P=0.962), 256.67±67.00 s ( t=0.880, P=0.472), 176.00±52.42 s ( t=-0.111, P=0.922), 58.67±14.84 s ( t=-0.832, P=0.493), respectively. There was no significant difference between the two systems ( P>0.05). The endoscopy tubes of the two endoscopic systems were both smooth. The operator was satisfied with the endoscopic procedures of both endoscopic systems, and no adverse event or device defect occurred. Conclusion:The portable endoscopic system proves to be safe and feasible for the diagnosis and treatment of abdominal trauma in animal models.

Objective:To investigate the current situation and influencing factors of the cognition of self-supporting for the elderly in nursing institutions, in order to provide a reference basis for constructing an intervention system of self-supporting in nursing institutions and implementing self-supporting more effectively.Methods:This study was a cross-sectional study. From April to August 2023, 320 elderly people from 7 elderly care institutions in Changsha City were selected by convenience sampling method, and the general information questionnaire, the Barthel Index Scale, the Comprehension Social Support Scale, and the self-developed questionnaire on knowledge belief, and practice of self-supporting for the elderly in nursing institutions were used to investigate. Multiple linear regression was used to analyze the factors influencing self-supporting for older people in nursing facilities.Results:Totally 315 valid questionnaires were recovered including 95 males and 220 females, with the majority aged 80-89 years, being 159. The surveyed elderly people in nursing institutions scored (91.24 ± 11.92) points on the self-supporting knowledge questionnaire, and the mean score of the entries was (3.51 ± 0.46) points. The results of multiple linear regression showed that the total scores of activity frequency, the Barthel index of activities daily living and perceived social support were the main factors affecting self-supporting ( t = 5.02, - 6.67, 9.48, all P<0.05), which could explain 51.8% of the total variation. Conclusions:The self-supporting of the elderly in nursing institutions is at a high level, and relevant personnel can better exert the subjective initiative of the elderly in nursing institutions by publicizing and educating the elderly on self-supporting, organizing regular activities and strengthening social support construction.

Objective:To translate the Cumulated Ambulation Score (CAS) into Chinese and test its reliability and validity in elderly inpatients, to provide a basis for assessing elderly inpatients′ basic mobility during hospitalization.Methods:This was a cross-sectional study. After obtaining the authorization of the original author, the Chinese version of CAS was formed by WHO′s cross-cultural translation process. A total of 414 hospitalized elderly inpatients from Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, and Shanghai Yangpu District Kongjiang Hospital were selected between March and September 2021. Cronbach′s α coefficient was used to test internal consistency, linear weighted Kappa was employed to assess inter-rater reliability, and concurrent validity was examined using items related to mobility of Barthel Index scores as a reference standard.Results:Of the 414 patients, 221 were males and 193 were females, and the patients aged (76.67 ± 9.98) years old; 122 cases (29.5%) had a perfect score of 6 with normal basic mobility, 89 cases (21.5%) had a score of 0 with complete loss of mobility, and the remaining 203 patients had a score of 1-5 with varying degrees of reduced mobility. The Chinese version of CAS demonstrated good assessment performance for basic mobility in elderly inpatients with a Cronbach′s α coefficient of 0.952. Weighted Kappa values for individual items and total scores showed excellent agreement among raters (>0.85), while concurrent validity yielded a value of 0.935 ( P<0.01) when compared with Barthel Index scores.Total score of CAS was significantly correlated with item scores and total score of Barthel index ( r values were 0.423 to 0.944, all P<0.01). Conclusions:The Chinese version of CAS has good reliability and validity. The items are concise, clear and easy to understand. It is suitable as a preliminary screening tool for clinical departments to evaluate the basic mobility of elderly inpatients.

Long non-coding RNAs (lncRNAs) play a significant role in maintaining tissue morphology and functions, and their precise regulatory effectiveness is closely related to expression patterns. However, the spatial expression patterns of lncRNAs in humans are poorly characterized. Here, we constructed five comprehensive transcriptomic atlases of human lncRNAs covering thousands of major tissue samples in normal and disease states. The lncRNA transcriptomes exhibited high consistency within the same tissues across resources, and even higher complexity in specialized tissues. Tissue-elevated (TE) lncRNAs were identified in each resource and robust TE lncRNAs were refined by integrative analysis. We detected 1 to 4684 robust TE lncRNAs across tissues; the highest number was in testis tissue, followed by brain tissue. Functional analyses of TE lncRNAs indicated important roles in corresponding tissue-related pathways. Moreover, we found that the expression features of robust TE lncRNAs made them be effective biomarkers to distinguish tissues; TE lncRNAs also tended to be associated with cancer, and exhibited differential expression or were correlated with patient survival. In summary, spatial classification of lncRNAs is the starting point for elucidating the function of lncRNAs in both maintenance of tissue morphology and progress of tissue-constricted diseases.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.
