Objective: To investigate the influencing factors for delay in healthcare-seeking, definitive diagnosis and identification in patients with pulmonary tuberculosis (PTB) in Minhang District, Shanghai Municipality, so as to provide the basis for effectively reducing delay in PTB patients. Methods: Data of PTB patients in Minhang District from 2017 to 2022 were collected from the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. The prevalence rates of delay in healthcare-seeking, definitive diagnosis and identification were analyzed, and factors affecting delay in healthcare-seeking, definitive diagnosis and identification were identified using multivariable logistic regression models. Results: A total of 4 214 PTB patients were reported in Minhang District from 2017 to 2022, including 2 802 males and 1 412 females, with a male-to-female ratio of 1.98∶1. The majority of patients were aged 25 to <45 years (1 664 cases, 39.49%). The prevalence rates of delay in healthcare-seeking, definitive diagnosis and identification were 36.81%, 30.21% and 38.09%, respectively. Delay in healthcare-seeking was associated with the year (2018, OR=0.708; 2019, OR=0.549; 2020, OR=0.670; 2021, OR=0.682), gender (female, OR=1.199), occupation (worker, OR=1.379; housekeeping service/housework/unemployed, OR=1.481), case identification route (symptom-based consultation, OR=11.159), and level of the first-diagnosed hospital (city-level, OR=1.528). Delay in definitive diagnosis was associated with age (45 to <65 years, OR=1.476), occupation (commercial service, OR=0.687; housekeeping service/housework/unemployed, OR=0.672), household registration (non-local, OR=0.820), case identification route (symptom-based consultation, OR=0.616), pathogen test result (negative/not tested, OR=1.903), and the level of the first-diagnosed hospital (city-level, OR=0.311). Delay in identification was associated with the year (2018, OR=0.785; 2019, OR=0.647; 2020, OR=0.790; 2021, OR=0.710), occupation (commercial service, OR=0.687), household registration (non-local, OR=0.848) and level of the first-diagnosed hospital (city-level, OR=0.560) Conclusions Year, gender, occupation, case identification route and level of the first-diagnosed hospital are influencing factors for delay in healthcare-seeking in PTB patients. Age, occupation, household registration, case identification route, pathogen test result and level of the first-diagnosed hospital are influencing factors for delay in definitive diagnosis. Year, occupation, household registration and level of the first-diagnosed hospital are influencing factors for delay in identification.

Objective: To investigate the effect of neurite outgrowth inhibitor extracellular peptide residues 1-40 (NEP1-40) combined with poly (lactic-co-glycolic acid) (PLGA) and gelatin electrospun fiber membrane on facial nerve repair in rats. Methods: According to the principle of random grouping, 108 male SD rats were divided into four groups (n = 27 in each group, approved by the ethics committee), namely, the sham group, control group, PLGA group, and NEP1-40 + PLGA group. A facial nerve fracture model was established for all of the groups except for the sham group. The control group received no further treatment, the PLGA group and the NEP1-40+PLGA group were supported by PLGA membrane, and the NEP1-40+PLGA group received one immediate local injection of NEP1-40 (5 μg/μL) at a dose of 10 μL. Facial nerve function analysis, electrophysiological examination, transmission electron microscope observation, HE staining, and immunohistochemical staining of myelin marker S100β and axonal marker β3-tubulin were used to evaluate the recovery of injured facial nerves of rats at 2, 4 and 8 weeks. Results : At 8 weeks, the facial nerve function score of the NEP1-40+PLGA group was better than that of the control group and PLGA group (P < 0.001), and facial nerve function was significantly restored. Electrophysiological examination of nerve action potentials at the injured facial nerve showed that the amplitude in the NEP1-40+PLGA group was higher than that of the control group and PLGA group (P < 0.001), but there was no significant difference in latency and conduction velocity results between the groups (P > 0.05). At 2, 4, and 8 weeks, transmission electron microscopy showed that the number of myelinated nerve fibers and myelin sheath thickness in the cross-section of the injured facial nerve in the NEP1-40+PLGA group were greater than those in the other groups (P < 0.05). At 8 weeks, HE staining showed that the facial nerves in the control group had partially recovered, but the overall cell distribution was uneven and the boundary with surrounding tissues was slightly blurred. In contrast, the NEP1-40+PLGA group had a relatively uniform cell distribution and a clearer boundary with surrounding tissues. At 2, 4, and 8 weeks, the immunohistochemical results showed that in the cross-section of the injuried facial nerve, NEP1-40 increased the expression of neural markers S100 β and β3-tubulin, especially β3-tubulin, which was close to normal levels (P > 0.05) Conclusion NEP1-40 is beneficial for the generation of new myelin sheaths and axons at the site of injury, and it can promote the repair and regeneration of injured facial nerves to a certain extent, thus accelerating the recovery of injured nerve function.

Objective: To investigate the epidemiological characteristics of human brucellosis in Jiande City, Zhejiang Province from 2005 to 2024, so as to provide the evidence for strengthening the prevention and control of brucellosis. Methods: Data on brucellosis cases and surveillance in Jiande City from 2005 to 2024 were collected through the Chinese Disease Prevention and Control Information System, the annual brucellosis surveillance reports from the Jiande Center for Disease Control and Prevention, and the annual summaries of brucellosis prevention and control efforts. The epidemiological characteristics of human brucellosis were analyzed using a descriptive epidemiological method. Results: A total of 1 125 individuals were monitored in Jiande City from 2005 to 2024, with 18 seropositive cases identified and the seropositivity rate of 1.60%. The average annual seropositivity rate from 2015 to 2024 was 3.35%, which was significantly higher than that of 0.57% from 2005 to 2014 (P<0.05). There were 10 confirmed brucellosis cases and 8 asymptomatic infections, with no reported deaths. The peak incidence occurred between March and August. Among the 16 towns (streets) in Jiande City, 8 reported brucellosis cases. Of the brucellosis cases, 14 were male and 4 were female, with a male-to-female ratio of 3.5∶1. The majority of cases (13 cases) were aged between 40 and 60 years. Occupational exposure was identified in 16 cases, all of whom were infected through direct hand contact with the excreta, secretions, or animal products of infected sheep or cattle. The primary source of infection was sheep, followed by cattle. Five strains of Brucella were isolated and cultured, all identified as Brucella melitensis biovar 3. Conclusions The brucellosis epidemic in Jiande City remained at a sporadic and low prevalence level from 2005 to 2024, with an increasing trend observed from 2015 to 2024. Male occupational groups aged 40 to 60 years were the key population for brucellosis prevention and control, and sheep were the primary source of infection.

Objective:To observe the expression of CD36 in hepatocellular carcinoma tissues and cell lines, and to investigate the effects of CD36 on the proliferation and migration abilities of human hepatocellular carcinoma cell lines and human hepatocellular carcinoma cell xenograft models in nude mice.Methods:Differences in the expression levels of CD36 transcripts in 371 hepatocellular carcinoma and paracancerous tissues were analyzed based on information from The Cancer Genome Atlas (TCGA) database. Cancer tissues and corresponding paracancerous tissues of 48 hepatocellular carcinoma patients who were diagnosed and underwent surgical treatment at the Affiliated Hospital of Yangzhou University from January 2019 to February 2021 were prospectively collected, and the levels of CD36 mRNA in the tissues were detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) method. Western blotting was used to detect CD36 protein levels in human hepatocellular carcinoma cell lines Huh7 and HCCLM3 and human normal liver cell line LO2. Plasmids containing CD36 interfering sequences and empty plasmids were transfected into Huh7 cells or HCCLM3 cells for sh-CD36 group and control group, respectively. The CCK-8 assay was used to detect the proliferation ability (expressed as absorbance value) of cells in each group at 0, 12, 24, 36, 48 and 60 h of culture, and the scratch healing assay and Transwell assay were used to detect the migration ability of cells in each group. The Huh7 cells of sh-CD36 group or control group were injected into the axillary subcutis of BALB/c nude mice, with 4 mice in each group, to construct nude mice models of human hepatocellular carcinoma xenografts; the long and short diameters of tumor were measured weekly after 1 week of inoculation, and the tumor volume was calculated. The nude mice were put to death after 5 weeks of inoculation, and the tumor specimens were collected and weighed; the tumor cell morphology was observed under the microscope, and the expressions of CD36 and Ki-67 proteins in the tumor tissues was detected by immunohistochemistry (IHC).Results:Analysis of the data from the TCGA database showed that the level of CD36 transcripts was higher in hepatocellular carcinoma tissues compared with that in paracancerous tissues (4.2±1.8 vs. 3.2±1.5, t = 2.28, P = 0.035). Tissues detection using qRT-PCR in 48 patients with hepatocellular carcinoma showed that the relative expression of CD36 mRNA in hepatocellular carcinoma tissues was higher than that in paracancerous tissues (0.76±0.26 vs. 0.48±0.23, t = 3.52, P < 0.001). Western blotting assay showed that CD36 protein level in Huh7 and HCCLM3 cells was higher than that in LO2 cells, which were (1.42±0.11) times and (1.68±0.16) times higher than LO2 cells, respectively (both P < 0.001). At the mRNA and protein levels, the CD36 of Huh7 and HCCLM3 cells in the sh-CD36 group was lower than that in the corresponding control group (both P < 0.001). CCK-8 assay showed that the proliferative ability of Huh7 cells and HCCLM3 cells in the sh-CD36 group was lower than that in the corresponding control group after 36 and 24 h of culture (both P < 0.01). Scratch healing assay showed that the scratch healing rates of Huh7 cells [(12±3)% vs. (30±5)%, t = 4.01, P < 0.001] and HCCLM3 cells [(15±4)% vs. (29±5)%, t = 4.16, P < 0.001] in the sh-CD36 group were lower than those in the corresponding control group at 48 h of culture; Transwell assay showed that the number of Huh7 cells [(46±6) cells/field of view vs. (88± 6) cells/field of view, t = 5.56, P < 0.001] and HCCLM3 cells [(42±5) cells/field of view vs. (82±7) cells/field of view, t = 5.34, P < 0.001] penetrating into the membrane in 24 h in the sh-CD36 group was less than that in the corresponding control group. Five weeks after subcutaneous injection, the tumor volume [(682±268) mm 3vs. (1 375±512) mm 3, t = 4.73, P = 0.006] and tumor mass [(432±95) mg/mouse vs. (871±109) mg/mouse, t = 6.57, P < 0.001] of nude mice injected with Huh7 cells of the sh-CD36 group were lower than those of nude mice injected with Huh7 cells of the control group; under the microscope, the density of tumor cells in transplanted tumor specimens of nude mice injected with Huh7 cells of the sh-CD36 group was lower than that in nude mice injected with Huh7 cells of the control group, and the expression levels of both CD36 and Ki-67 proteins were also low. Conclusions:CD36 expression is up-regulated in cancer tissues of hepatocellular carcinoma patients and human hepatocellular carcinoma cell lines Huh7 and HCCLM3, and it may associate with cell proliferation and migration of hepatocellular carcinoma. Knockdown of CD36 expression significantly inhibits the proliferation and migration abilities of hepatocellular carcinoma cells in vitro, and inhibits the tumors of human hepatocellular carcinoma cell xenograft models in nude mice.

【Objective】 To investigate the development of adaptability in children aged 2 - 6, and to explore its influencing factors, so as to provide reference for promoting the development of adaptability in young children. 【Methods】 Data were from the National Nutrition and Health Systematic Survey for Children in China, and 3 319 children aged 2 - 6 and their parents from 28 sites across 14 provinces were recruited in this study.The Development Scale for Children Aged 0 - 6 years (WS/T 580-2017) was used to measure the developmental quotient of children′s adaptive ability, and a survey questionnaire was used to collect relevant information about children and their parents. 【Results】 Among 3 319 children aged 2 - 6, the proportion of slightly low or low level of adaptability, moderate adaptability development, good and excellent adaptability development was 7.68%,66.25% and 26.06%, respectively.The proportion of children aged 5 - 6 with good and excellent adaptability was lower in 3-year-old and 4-year-old groups (χ²=59.29, P<0.05).Multiple stepwise linear regression showed that children′s gender (β=0.06), gestational age of birth (β=-0.05), only child (β=-0.04), left-behind child (β=-0.04), the main caregiver (β=-0.06), and the education level of parents (β=0.09, 0.10), whether parents actively pay attention to children′s emotions (β=-0.06) and whether children play with homemade toys (β=-0.04) were the influencing factors of children′s adaptive development quotient.Girls, full-term children, only children, non-left-behind children, children with parents as main caregivers, parents with a high level of education, parents who often take the initiative to pay attention to children′s emotions, and children who play with homemade toys had a higher level of adaptability development quotient. 【Conclusions】 The development level of adaptability in children aged 2 - 6 in China is mostly above the average level and is related to multiple factors.Targeted intervention work can be carried out on relevant factors in order to promote the development of children′s adaptability.

The primary outcome was the Toronto facial grading system （SFGS）， and the secondary outcomes included house-brackmann （H-B） grade， facial disability index （FDI） score， and number of H-B grade-Ⅰ cases. Adverse events were recorded in both groups. ResultsThe SFGS scores of the patients in both groups were higher on the 10th， 30th and 45th days after onset of disease compared with those before the treatment （P＜0.05）； the H-B grade was lower on the 30th and 45th days after the onset of the disease compared with those before the treatment （P＜0.05）； and the facial disability index physical function （FDIP） and facial disability index social function （FDIS） scores were higher on the 30th and 45th days after onset of disease （P＜0.05）. SFGS scores of patients in the treatment group were significantly higher than those of the control group on the 30th and 45th days after onset （P＜0.05）； H-B grade was significantly lower than that of the control group on the 30th and 45th days after onset （P＜0.05）； and FDIP scores on the 45th day after onset， and FDIS scores on the 30th and 45th days after onset were significantly higher than those of the control group （P＜0.05）. At the end of treatment， 77.50% （31 cases） achieved H-B grade-Ⅰ in the treatment group， which was more than 55.00% （22 cases） in the control group （P＜0.05）. No adverse events occurred in either group. ConclusionElectroacupuncture combined with point bloodletting and cupping for IFP in acute stage can improve the recovery degree of facial nerve function， improve effectiveness， and show a high degree of safety.

ObjectiveIn order to improve the recognition accuracy of named entities in medical record texts and realize the effective mining and utilization of medical record knowledge， a Bert-Radical-Lexicon（BRL） neural network model is constructed to recognize medical record entities with respect to the characteristics of medical record texts. MethodWe selected 408 medical records related to hypertension from the the Complete Library of Famous Medical Records of Chinese Dynasties and constructed a dataset consisting of 1 672 medical records by manually labeling. Then， we randomly divided the dataset into three subsets， including the training set（1 004 cases）， the testing set （334 cases） and the validation set（334 cases）. Based on this dataset， we built a BRL model that fused various text features of medical records， as well as its variants BRL-B， BRL-L and BRL-R， and a baseline model Base for experiments. During the model training phase， we trained the above models using the training set to reduce the risk of overfitting. We continuously monitored the performance of each model on the validation set during training and saved the model with the best performance. Finally， we evaluated the performance of these models on the testing set. ResultCompared with other models， the BRL model had the best performance in the medical records named entity recognition task， with an overall recognition precision of 90.09%， a recall of 90.61%， and the harmonic mean of the precision and recall（F1） of 90.35% for eight types of entities， including disease， symptom， tongue manifestation， pulse condition， syndrome， method of treatment， prescription and traditional Chinese medicine（TCM）. Compared with the Base model， the BRL model improved the overall F1 value of entity recognition by 5.22%， and the F1 value of pulse condition entity increased by 6.92%， which was the largest increase. ConclusionBy incorporating a variety of medical record text features in the embedding layer， the BRL neural network model has stronger named entity recognition ability， and thus extracts more accurate and reliable TCM clinical information.

Objective To investigate the effect of baicalin(BA)regulating cyclic adenosine phosphate(cAMP)/protein kinase A(PKA)/cAMP response elemen-binding protein(CREB)pathway on skin barrier function in eczema rats.Methods SD rats were randomly divided into the control group(NC group),the model group,the low-dose BA group(BA-L group,25 mg/kg),the medium-dose BA group(BA-M group,50 mg/kg),the high-dose BA group(BA-H group,100 mg/kg),the prednisone group(PNS group,25 mg/kg),the BA-H+cAMP inhibitor(SQ22536)group(100 mg/kg+2.13 mg/kg)and the BA-H+PKA inhibitor(H-89)group(100 mg/kg+5 mg/kg),12 animals in each group.Except for the NC group,eczema rat model was constructed in the other groups.Two days after successful modeling,drug administration was performed in groups.Changes of eczema area and severity index(EASI)score,transcutaneous water loss(TEWL)and cuticle water content(WCSC)were detected.Enzyme-linked immunosorbent assay(ELISA)was used to detect levels of immunoglobulin E(IgE),interferon-γ(IFN-γ)and interleukin-4(IL-4)in rat serum and the expression of cAMP protein in rat back lesions.HE staining was used to detect pathological changes of skin lesions on the back of rats.Western blot assay was used to detect aquaporin 3(AQP3),cathelicidin related antimicrobial peptide(CRAMP),p-PKA,p-CREB protein expression in rat back lesions.Results Compared with the NC group,rats had serious pathological lesions on the back of the tested area,increased EASI score,TEWL,IgE and IL-4 levels,and decreased WCSC,IFN-γ,AQP3,CRAMP,cAMP,p-PKA and p-CREB protein levels in the model group(P<0.05).Compared with the model group,pathological lesion of the tested area in the back of rats was relieved,and EASI score,TEWL,IgE and IL-4 levels were decreased,WCSC,IFN-γ levels,AQP3,CRAMP,cAMP,p-PKA and p-CREB protein were increased in the BA-L group,the BA-M group,the BA-H group and the PNS group(P＜0.05).Changes of above indexes in the BA-L group,the BA-M group,the BA-H group were dose-dependent.SQ22536 or H-89 attenuated the improvement effect of high dose BA on skin barrier function in eczema rats.Conclusion BA may improve skin barrier function in eczema rats by activating cAMP/PKA/CREB signaling pathway.
