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 explore the genetic basis for a child with multiple malformations. METHODS: A child who had presented at Shanxi Provincial Children's Hospital in February 2021 was selected as the study subject. Clinical data of the patient was collected, and whole exome sequencing (WES) was carried out to screen pathogenic variants associated with the phenotype. Candidate variant was validated by Sanger sequencing of her family members. RESULTS: The child had normal skin, but right ear defect, hemivertebral deformity, ventricular septal defect, arterial duct and patent foramen ovale, and separation of collecting system of the left kidney. Cranial MRI showed irregular enlargement of bilateral ventricles and widening of the distance between the cerebral cortex and temporal meninges. Genetic testing revealed that she has harbored a heterozygous variant of NM_178014.4: c.217A>G (p.Met73Val) in the TUBB gene, which was unreported previously and predicted to be likely pathogenic based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). The child was diagnosed with Complex cortical dysplasia with other brain malformations 6 (CDCBM6). CONCLUSION CDCBM is a rare and serious disease with great genetic heterogeneity, and CDCBM6 caused by mutations of the TUBB gene is even rarer. Above finding has enriched the variant and phenotypic spectrum of the TUBB gene, and provided important reference for summarizing the genotype-phenotype correlation of the CDCBM6.

Objective:To analyze the clinical features of patients with severe dengue (SD) in Guangdong Province, and to improve the understanding of the diagnosis and treatment of SD in China.Methods:The clinical data, laboratory examination and etiological test results of 257 SD cases from 29 dengue fever designated hospitals in Guangdong Province from January 1, 2013 to December 31, 2019 were respectively collected. The relevant indicators of the criteria for severe organ involvement were quantified. Logistic regression analysis was performed to analyze the risk factors for the development of multiple organ failure in SD patients.Results:Among the 257 SD patients, age was (64.1±20.1) years old, with 65.4%(168/257) of them ≥60 years old, 142 were male and 115 were female. One hundred and fifty-two (59.1%) patients had underlying conditions, including 115(44.7%) patients with hypertension. The clinical manifestations were mainly fever (98.4%(253/257)), fatigue (70.0%(180/257)), cough or expectoration (44.4%(114/257)), lethargy or irritability (39.3%(101/257)), vomiting (30.4%(78/257)), abdominal pain or tenderness (20.6%(53/257)), hepatomegaly (2.3%(6/257)), bleeding tendency (59.5%(153/257)), and pleural effusion or ascites (43.6%(112/257)). Platelet count levels were decreased in 90.9%(231/254) of the cases, and 97.1%(234/241) of patients had normal or decreased hematocrit. The most common of severe manifestations were severe organ involvement (61.1%(157/257)), followed by severe bleeding (37.0%(95/257)) and severe plasma leakage (30.0%(77/257)). Severe organ involvements were more common in the kidney (27.6%(71/257)) and heart (26.8%(69/257)). Multivariate logistic regression analysis showed that age (odds ratio ( OR)=1.051, 95% confidence interval ( CI) 1.004 to 1.100, P=0.035), hypertension ( OR=5.224, 95% CI 1.272 to 21.462, P=0.022), elevated aspartate aminotransferase (AST) level ( OR=1.002, 95% CI 1.001 to 1.003, P=0.001), blood urea nitrogen (BUN) ( OR=1.050, 95% CI 1.005 to 1.098, P=0.030), and international normalized ratio (INR) ( OR=4.604, 95% CI 1.601 to 13.238, P=0.005) were risk factors for the development of multiple organ failure in SD patients. The detection results of serum samples form 113 SD patients in acute phase showed that dengue virus (DENV)-1 accounted for 89.4%(101/113), DENV-2 accounted for 9.7%(11/113), and DENV-3 accounted for 0.9% (1/113). Conclusions:Elderly and those with co-existing conditions such as hypertension in SD patients in Guangdong Province are more common. Severe organ involvement such as kidney and heart is the main cause of SD. DENV-1 infection is predominant. Significant elevated levels of AST, BUN and INR may be related to a poor prognosis.

Transcription factors, the proteins with special structures, can bind to specific sites and regulate specific expression of target genes. NAC (NAM, ATAF1/2, CUC1/2) transcription factors, unique to plants, are composed of a conserved N-terminal domain and a highly variable C-terminal transcriptional activation domain. NAC transcription factors are involved in plant growth and development, responses to biotic and abiotic stresses and other processes, playing a regulatory role in flower development. In this paper, we reviewed the studies about NAC transcription factors in terms of discovery, structure, and regulatory roles in anther development, other floral organ development and flowering time. This review will provide a theoretical basis for deciphering the regulatory mechanism and improving the regulatory network of NAC transcription factors in flower development.

Objective To investigate the epidemic characteristics of pulmonary tuberculosis (TB) in Minhang District of Shanghai, and to provide a scientific basis for TB prevention and control. Methods Data from active TB patients registered in Minhang District of Shanghai from 2009 to 2019 was collected and analyzed using descriptive epidemiological method. Results From 2009 to 2019 the registration rates of TB patients in Minhang district of Shanghai showed a downward trend, with an average annual registration rate of 32.35/100 000, including 3 611 (41.08%) patients who were registered permanent residents of Shanghai and 5 179 (58.92%) patients who were non-permanent residents. The ratio of men to women was 2.04:1. Workers accounted for more cases (22.77%) than other occupations among patients without registered permanent residence, while retirees accounted for the majority of cases (38.60%) among patients with registered permanent residence. Among the TB patients without registered residence, the highest proportion (45.86%) was in the 20-29 years old group, while the highest proportion in permanent residents was in the 50-59 years old group (19.47%). The peak incidence occurred in May in patients without registered permanent residence, while the peak incidence was in June in patients with registered permanent residence. Conclusion It is necessary to strengthen the prevention and control of TB in people without registered permanent residence of Shanghai, and at the same time, to strengthen the prevention and control of TB in old people and students with registered permanent residence of Shanghai.

Objective: To investigate the optimal duration of pegylated-alpha interferon (Peg-INFα) combined with ribavirin (RBV) in treating chronic hepatitis C infection in human immunodeficiency virus (HIV)-infected patients. Methods: A multicenter prospective study was conducted. The study subjects were divided into two groups; HIV/HCV co-infections (Group A, n = 158) and control with HCV-monoinfections (Group B, n = 60). All recruited patients received standard Peg-INFα plus RBV therapy. Group A was divided into 3 subgroups according to CD4⁺ cell counts: A1 subgroup, 79 cases, CD4⁺ counts > 350 cells /μl, who received anti-HCV before combination antiretroviral therapy(cART); A2 subgroup, 45 cases, CD4⁺ counts between 200 and 350 cells/μl, who did not start anti-HCV until they could tolerate cART well; A3 subgroup, 34 cases, CD4⁺ counts < 200 cells /μl, cART was administered first, and anti-HCV therapy was started when CD4⁺ counts > 200 cells/μl. The anti-HCV efficacy of two groups and 3 subgroups were compared. Statistical analysis for normal distribution and homogeneity of variance data was calculated by t-test and the counting data was analyzed by χ ² test. The Mann-Whitney U test was used for non-normal data. A one-way analysis of variance (ANOVA) was used for the comparison of multiple groups, followed by SNK method. Multiple independent samples were used for non-parametric tests. Results: There was no significant difference in age and baseline HCV RNA levels between groups and subgroups (P > 0.05). By an intent-to-treat (ITT) analysis, in Group A, the ratio of complete early virological response (cEVR) rate was 75.3% (119/158), the ratio of end of treatment virological response (eTVR) rate was 68.4% (108/158), and the ratio of sustained virological response (SVR) rate was 48.7% (77/158); in Group B, the ratio of cEVR rate was 93.3% (56/60), the ratio of eTVR rate was 90.0% (54/60), and the ratio of SVR rate was 71.7% (43/60); The therapeutic index of Group A were lower than those of Group B (P≤0.05). By per-protocol (PP) analysis, the ratio of cEVR rate in Group A [75.2% (88/112)] was still lower than that in Group B [93.3% (56/60)], but no significant differences were found in the ratio of eTVR rate and SVR rate between 2 groups (P > 0.05). Comparing the efficacy of subgroups (A1, A2 and A3) by ITT analysis, the ratios of cEVR rate were respectively 78.5% (62/79), 75.6% (34/45) and 67.6% (23/34); the ratios of eTVR rate were respectively 68.4%(54/79), 80.0%(36/45)and 52.9%(18/34); and the ratios of SVR rate were respectively 41.8%(33/79), 64.4%(29/45)and 44.1%(15/34). The ratio of eTVR in subgroup A2 was obviously higher than that in subgroup A3 and the ratio of SVR in subgroup A2 was statistically higher than that of subgroup A1(P≤0.05). However, by PP analysis, no significant differences of the therapeutic indexes were found among the respective subgroups (P > 0.05). Conclusion HIV-HCV co-infected patients would have better anti-HCV efficacy with Peg-INFα-2a plus RBV than HCV- monoinfected patients. The best time for initiating anti-HCV therapy in HIV-HCV co-infected patients is when CD4⁺ counts 200 cells/ μl.

Objective To explore the application effects of the construction of the pain management decision and quality monitoring system in big data era.Methods A total of 114 patients who were in Oncology Department ward from January to June 2016 when the system of pain management decision and quality monitoring had not been applied were selected as the control group. After the application of pain management decision and quality monitoring system, from July to December 2016, 132 patients of Oncology Department ward were selected as the observation group. The qualified rate of pain nursing record, the degree of pain relief and pain management satisfaction were statistically analyzed and compared between the two groups. Results After application of pain management decision and the quality monitoring system software, the pain assessment accuracy, the qualified rate of pain nursing records and pain management satisfaction of the observation group increased significantly than those of the control group, and the difference was statistically significant (P<0.05). The degree of pain relief in patients was significantly improved than that before the application, and the difference was statistically significant (P<0.05).Conclusions The application of pain management decision and quality monitoring system promotes the standardization of pain care and improves the efficiency of pain management.

Objective To analyze the key factors influencing the number of diseases or conditions in which clinical pathways ( CPs) were implemented at public hospitals of China. Methods Based on the questionnaire survey of 51 public hospitals that had implemented CPs in Shanghai, Hubei province, and Gansu province, a multivariate logistic model was used to analyze the factors that influenced the number of CPs implemented in hospitals. Results In terms of the 14 issues and difficulties found in CPs′implementation, the overall acceptance rate was 38. 8% on average among surveyed hospitals, yet with a great variation(from 7. 1% to 100. 0%). A multivariate logistic model showed that the recognition of public hospitals on the issues and difficulties in CPs′implementation did not affect the number of implemented CPs, and tertiary public hospitals had significantly higher number of CPs implemented than secondary hospitals. Conclusions The resources and management capabilities of public hospitals in China are the determinants of CPs′promotion.

Objective To study the compliance of medical care with corresponding national clinical pathways for inpatients of cholecystectomy for cholecystolithiasis with acute cholecystitis at public hospitals of China. Methods Thirty medical records of the inpatients with cholecystectomy admitted in 2014 were randomly sampled from 18 public hospitals in Shanghai, Hubei province and Gansu province, for assessment on their compliance with corresponding national clinical pathways. Results The average compliance rate of inpatient care of cholecystectomy at public hospitals was 67. 7%. The study found low compliance rates in both severity assessment and timely examinations/diagnosis within two days after admission ( 5. 8% and 35. 3%, respectively) . Conclusions Public hospitals in China should strengthen their supervision over the medical care process for inpatients of cholecystectomy with acute cholecystitis, and the clinical pathways in question should be updated and improved in time.
