Objective:To explore the effects of high-efficiency centering pregnancy care (CPC) combined with information-knowledge-attitude-practice (IKAP) health education on cesarean delivery on maternal request (CDMR) rate, maternal and neonatal health status so as to provide referential significance for reducing CDMR rate and improving postpartum maternal and neonatal health status and breastfeeding rate.Methods:In the prospective, single-center and controlled study, a total of 82 primiparas undergoing antenatal examination and delivery in South Binhu Hospital of Hefei First People′s Hospital were enrolled as the research objects between January 2020 and December 2021 by convenience sampling method, including 41 cases given routine health care in routine group between January and December 2020 and 41 cases given high-efficiency CPC combined with IKAP health education on basis of routine group in combination group between January and December 2021. The cognition of cesarean section, delivery modes, incidence of postpartum complications, neonatal complications and breastfeeding between the two groups were compared.Results:The age of the routine group was (26.71 ± 2.18) years old, and the age of the combination group was (27.16 ± 1.79) years old. The proportions of correct cognition, partially correct cognition and incorrect cognition to cesarean section in combination group were 73.17% (30/41), 21.95% (9/41), 4.88% (2/41), and 53.66% (22/41), 26.83% (11/41), 19.51% (8/41) in routine group, and the difference between the two groups was statistically significant ( Z = 4.22, P<0.05). The incidence of cesarean section and CDMR in combination group was 24.39% (10/41) and 1/10, lower than that in routine group [46.34% (19/41), 10/19], and the difference between the two groups was statistically significant ( χ2 = 4.32, P<0.05; Fisher′s exact test, P = 0.049 ). The total incidence rates of postpartum complications of primiparas and neonatal complications in the combination group were 4.88%(2/41) and 7.32%(3/41), lower than 12.20%(5/41) and 12.20%(5/41) in the routine group, and the differences between the two groups were not statistically significant (Fisher′s exact test, P = 0.432, 0.712). The scores of functional health literacy, communicative health literacy and critical health literacy in combination group were (85.73 ± 4.09), (51.93 ± 4.72) and (58.63 ± 4.32) points, higher than those in routine group [(80.17 ± 5.26), (46.37 ± 5.11) , (52.71 ± 5.07) points], and the difference between the two groups was statistically significant ( t = 5.34, 5.12, 5.69, all P<0.01). At 3 months after delivery, exclusive breastfeeding rate, milk powder feeding rate and mixed feeding rate in combination group were 58.54% (24/41), 7.32%(3/41), 34.15(14/41), higher than 26.83% (11/41), 29.27(12/41), 43.90%(18/41) in routine group, and the difference between the two groups was statistically significant ( χ2 = 10.73, P<0.05). Conclusions:High-efficiency CPC combined with IKAP health education can reduce incidence of CDMR, decrease maternal and neonatal complications, enhance maternal postpartum health literacy and improve breastfeeding rate in primiparas by improving correct cognition to cesarean section. It is worthy of clinical application.

Objective To investigate the expression of Thymosinβ10(TMSB10)in gastric cancer and its molecular mechanism in promoting the progression of gastric cancer.Methods We collected pathological sections of 70 patients with gastric cancer in our hospital,detected expression of TMSB10 in gastric adenocarcinoma by immunohistochemistry,and analyzed its prognostic effect.In order to study the mechanism of action,the effects of TMSB10 on the proliferation and glycolysis of gastric cancer cells and its related mechanism were observed by trans-fection technique,CCK8 test,EDU assay,Transwell assay,scratch test,glycolysis assay and Western blot.Results Immunohistochemistry showed that TMSB10 was highly expressed in gastric cancer,while the expression level of TMSB10 was correlated with tumor size(P=0.032),TNM stage(P=0.002)and distant metastasis.In the mechanism study,we found that overexpression of TMSB10 promoted the proliferation,invasion,migration and glycolytic phenotype of gastric cancer cells through in vitro CCK-8 test,EDU assay,Transwel assay and glycolysis assay,and vice versa.Western blot results showed that overexpression of TMSB10 may regulate the occurrence of gastric cancer through up-regulation of the AMPK/mTOR signaling pathway.Conclusions TMSB10 promotes the proliferation,invasion,migration and glycolysis gastric cancer through the AMPK/mTOR signaling pathway.

ObjectiveTo identify the rate， population characteristics， and vaccination history of repeat infections among previously infected people in the current epidemic based on the rate of repeat infection and population characteristics of different mutant strains at different times in Pudong New Area of Shanghai， and to provide reference for the prevention and control strategies of novel coronavirus repeat infections. MethodsA total of 9 250 investigated subjects were randomly selected from the new cases of asymptomatic infection and confirmed cases reported by Pudong New Area from March to May 2022. The investigation mainly focused on demographic characteristics， nucleic acid or antigen test results， and symptoms after infection. The repeat infection rates among different populations were compared， and logistic regression was used to analyze the impact of gender， age， and vaccination status on repeat infections. ResultsThe survey sample of 9 250 people had a response rate of 81.85%. There were 4 043 males （53.40%） and 3 528 females （46.60%）， with a median age of 34 years old （P₂₅， P₇₅： 7， 61）. The overall vaccine uptake rate was 59.44% （4 500/7 571）. In December of 2022， there were 563 cases of repeat infection， with an infection rate of 7.44%. The lowest rate of repeat infection was seen in the 3‒ year-old group （2.86%） and the highest rate in the 30‒ year-old group （12.42%）， with significant differences between different age groups. The repeated infection rate for those who had completed their vaccinations was significantly lower （6.57%） compared to those who had not （7.11%）. The age groups of 3‒ years， 70‒79 years， as well as individuals who completed full vaccination and received booster shots were protective factors against repeat infections. ConclusionThe overall rate of reinfection among the infected in Shanghai during the spring of 2022 was low in the outbreak of the Omicron variant， and the rate of reinfection in the 3‒ year-old group was significantly lower than in other age groups. Completing the full course of vaccination significantly reduces the risk of reinfection. Although the reinfection rate is high in individuals who received booster shots， it remains a mitigating factor compared to those who do not receive the vaccine. It is recommended to continue monitoring reinfections in key populations and further strengthen immunization efforts.

ObjectiveTo analyze the epidemiological characteristics and etiology of clustered outbreaks of hand， foot， and mouth disease （HFMD） in Pudong New Area， Shanghai from 2017 to 2022， and to provide a scientific basis for the prevention and control of HFMD in the area. MethodsThe data related to HFMD clustered outbreaks from 2017 to 2022 were obtained from the Pudong New Area HFMD outbreak database. Descriptive analysis was conducted to explore the outbreak scope， seasonal characteristics， distribution of occurrence settings， and etiological composition. ResultsFrom 2017 to 2022， Pudong New Area reported a total of 2 547 HFMD clusters， involving 8 884 cases， with an average of 3.49 cases per event. The majority of events （78.52%） had between 2 and 4 cases. The peak reporting periods for clustered HFMD from 2017 to 2019 and in 2021 were during the summer （May‒July） and autumn （September‒November）. The seasonal pattern was less distinct in 2020 and 2022， likely due to the impact of the COVID-19 pandemic. The majority of clustered outbreaks occurred in childcare facilities （44.64%）， followed by households/neighborhood committees （44.21%）， with schools accounting for a smaller proportion （12.39%）. The etiology revealed the coexistence of multiple enterovirus genotypes， with a positive detection rate of 60.46%， and CoxA6 being the dominant strain. ConclusionHFMD clustered outbreaks in Pudong New Area show fluctuating trends， with significant yearly differences in the number of incidents. The predominant seasons for outbreaks are summer and autumn， with CoxA6 identified as the dominant strain. The implementation of prevention and control measures for COVID-19 significantly reduced the occurrence of HFMD outbreaks. Continuous monitoring and focus on large-scale clustered outbreaks in key institutions are essential for the future.

Objective:To investigate the etiological mechanism in single small subcortical infarction (SSSI) with different imaging features.Methods:The patients registered in a database of ischemic stroke in the Department of Neurology of the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2019 were analyzed. According to the lowest slice (LS) and the total number of involved slices (TNS) on diffusion-weighted imaging, the SSSI was divided into 3 types: proximal SSSI (pSSSI; LS≤2), distal and large SSSI (dl-SSSI; LS>2, TNS>2) and distal and small SSSI (ds-SSSI; LS>2, TNS≤2). The clinical and imaging features among 3 different lesion patterns were compared by using χ 2 test, Kruskal-Wallis H test and multiple Logistic regression analysis, etc. Results:In the 3 groups of ds-SSSI ( n=205), dl-SSSI ( n=157) and pSSSI ( n=166), the prevalences of parent artery disease (PAD)[10.7% (22/205) , 19.1% (30/157) , 42.8% (71/166), respectively, χ 2=54.89, P<0.001], coronary artery disease [8.3% (17/205), 14.0% (22/157), 16.9%(28/166), respectively, χ 2=6.44, P=0.040] and severe white matter hyperintensities (sWMHs)[58.0% (119/205), 43.3% (68/157), 41.0% (68/166), respectively, χ 2=12.94, P<0.001], the level of serum homocysteine (Hcy)[18.01 (13.54, 25.56), 16.03 (12.50, 21.09), 14.72 (11.12, 19.14) μmol/L, respectively, H=19.36, P<0.001], and the National Institutes of Health Stroke Scale (NIHSS) score[2(1, 3), 3(1, 4), 3(2, 6), respectively, H=39.53, P<0.001] showed statistically significant differences. Multiple Logistic regression analysis showed that compared with dl-SSSI patients, the lesion pattern of patients with higher proportion of PAD ( OR=3.12, 95% CI 1.86-5.24, P<0.001) was closer to pSSSI; the lesion pattern of patients with higher serum Hcy level ( OR=1.02, 95% CI 1.00-1.04, P=0.046) or higher proportion of sWMHs ( OR=1.79, 95% CI 1.12-2.86, P=0.015) was closer to ds-SSSI, and the lesion pattern of patients with higher proportion of PAD ( OR=0.50, 95% CI 0.27-0.93, P=0.029) or higher NIHSS score ( OR=0.84, 95% CI 0.77-0.92, P<0.001) was closer to dl-SSSI. Conclusions:The pathogenesis of ds-SSSI tends to be cerebral small vessel disease. The pathogenesis of pSSSI is related to atherosclerosis. The patients with dl-SSSI have the intermediate characteristics of pSSSI and ds-SSSI and may be unstable.

The global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has had a catastrophic impact on human life and economic life. Due to the combination of multiple underlying diseases and low vaccination rates, dialysis patients are susceptible to SARS-CoV-2 infection and are likely to have more severe illness and even death. Moreover, dialysis patients with SARS-CoV-2 infection may initially present as asymptomatic or with mild symptoms, which makes it very difficult to identify severe patients at an early stage. Here, the epidemiology, clinical characteristics, risk factors for prognosis, vaccination and therapeutic strategies of dialysis patients with SARS-CoV-2 infection were summarized and analyzed, and it is hoped to provide a reference for the diagnosis and treatment of SARS-CoV-2 infection in this special group of patients.

Objective:To investigate the relationship between the protein expression of C-MYC, bcl-2 and bcl-6 and the clinicopathological characteristics in patients with de novo CD5-positive diffuse large B cell lymphoma (CD5 +DLBCL). Methods:Fifty seven cases of de novo CD5 +DLBCL were collected at Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from February 2013 to September 2018. The hematoxylin-eosin stained slides were reviewed, and immunohistochemical (IHC) staining and FISH were used to analyze the relationship between C-MYC, bcl-2, bcl-6 expression and the clinicopathologic characteristics of patients. Results:Among these 57 cases, 27 were male and 30 were female. The age of onset was 35-99 years old. The IHC expression rates of C-MYC, bcl-2 and bcl-6 were 50.9% (29/57), 84.2% (48/57), and 75.4% (43/57) respectively; and co-expression rate of C-MYC and bcl-2 proteins was 40.4 (23/57). There was no significant correlation between protein expression and patients′ genders, clinical stage, the level of serum LDH,β2 microglobulin, IPI,B symptoms, bone marrow involvement and central nervous system recurrence ( P>0.05). Univariate analysis showed that the median OS of C-MYC negative patients was significantly longer than C-MYC positive patients ( P<0.05); and the median OS of patients without double expression was significantly longer than that of patients with positive expression ( P<0.05), and bcl-6 positive patients had longer median OS than bcl-6 negative patients ( P<0.05). There was no significant correlation between prognosis and bcl-2 protein expression ( P>0.05) . Cox multivariate analysis showed C-MYC protein expression was an independent predictor of OS in de novo CD5 +DLBCL ( P<0.05). Conclusions:Bcl-2 protein expression has no effect on the prognosis in de novo CD5 +DLBCL whereas bcl-6 expression is correlated with good prognosis. C-MYC protein expression could be used as an independent and effective index to predict the prognosis of patients with de novo CD5 +DLBCL.However, the relationship between protein expression and gene rearrangement of C-MYC, bcl-2 and bcl-6 needs to be further explored.

Objective: Explore the function and regulatory mechanism of Annexin A1 (ANXA1) in bladder cancer cell proliferation, apoptosis and migration. Methods: From February 2018 to June 2019, we use T24 cells as the model and divide it into over-expression control group (ctrl), ANXA1 over-expression group (ANXA1), knockdown control group (shctrl), ANXA1 knockdown group 1 (shANXA1-1), ANXA1 knockdown group 2 (shANXA1-2) and ANXA1 knockdown group 3 (shANXA1-3). 24 hours after the culture, the cells were collected and the mRNA expression level of ANXA1 was detected by Real-Time quantitative PCR. The cell activity was detected by CCK-8; the cell apoptosis and cycle were detected by flow cytometry. The cell migration was detected by Transwell assay. Results: The Real-Time quantitative PCR showed that the expression of ANXA1 in the over expression group was significantly higher than that in the over expression control group (15 369.00±874.20 and 1.00±0.07, P<0.001). The expression of ANXA1 in the knockdown group 2 and 3 were significantly lower than that in the knockdown control group (0.51±0.04, 0.51±0.02 and 1.00±0.04, P<0.001). Compared with the over expression control group(1.61±0.01), the cell activity of the over expression group(2.04±0.02)was significantly increased (P<0.001), while the activity of the knockdown group 2 and 3 (1.40±0.002 and 1.31±0.003)were significantly decreased than the knockdown ctrl group (1.73±0.01)(P<0.001). The results of flow cytometry showed that the number of G₀/G₁ cells in the over-expression group was significantly lower than that in the over-expression control group (28.14±0.33 and 46.19±0.73, P<0.001), while that in the knockdown group 2 and 3 were significantly higher than that in the knockdown control group (58.670±0.49, 62.34±4.01 and 45.59± 0.19, P<0.001 and P<0.05). There was no significant difference in the number of apoptosis between the over-expression group and the over-expression control group (P>0.05), while the number of apoptosis in the knockdown group 2 and 3 were significantly higher than that in the knockdown control group (13.04%, 14.58% and 7.76%, P<0.001). Cell function analysis showed that the number of cells passing through the membrane of the over expression group was significantly higher than that of the over expression group (525.00±9.30 and 385.70±13.40, P<0.01), while that of the knockdown group 2 and 3 were significantly lower than that of the knockdown control group (214.70±6.40, 226.00±5.30 and 398.70±10.00, P<0.001). Conclusions Over-expression of ANXA1 significantly promoted the proliferation, cycle and migration of T24 cells and inhibited apoptosis. On the contrary, ANXA1 knockdown inhibited the proliferation, cycle and migration of T24 cells and promoted apoptosis.
