ObjectiveTo explore the compliance related factors of repeated screening for colorectal cancer in Jiading District， and to provide a scientific basis for the prevention and control of colorectal cancer. MethodsBased on the natural population cohort in Jiading District， and the screening situation in 2017‒2019 and 2020‒2022， the study subjects were divided into the groups of never participating in screening and participating in screening. Subjects in the participating group were further divided into participating in one round of screening or having repeated screening. SPSS 21.0 software was used to analyze the demographic characteristics of each group. χ² test or Fisher precise probability test were used to conduct univariate analysis of the factors such as gender， age， education level， marital status， retirement status， and type of medical insurance. Factors with the significant difference （P<0.05） were selected for inclusion in multivariate analysis， and factors related to compliance with repeated screening were analyzed by multivariate logistic regression. ResultsA total of 8 179 subjects were included in the study， including 3 323 males （40.6%） and 4 856 females （59.4%）. The average age of the subjects was （61.26±6.06） years old. A total of2 652 （32.4%） had educated in primary school or below， 4 242 （51.9%） in secondary school， and 1 285 （15.7%） in higher secondary school. Mostly， 7 579 （92.7%） were married. Among the participants， 4 062 people had never participated in screening， 4 117 people had participated in screening， and 1 485 of them had repeated screening， with a repeated screening rate of 18.2%. Multivariate logistic regression analysis showed that women had better compliance with repeated screening than men （OR=1.31， 95%CI： 1.14‒1.50）. Compared with the population aged 50 to 54 years， the population aged 55‒59 years （OR=1.57， 95%CI： 1.19‒2.08）， 60-64 years （OR=2.77， 95%CI： 2.13‒3.61）， and 65-69 years （OR=3.31， 95%CI： 2.51‒4.36） had higher compliance with repeated screening. Compared with employees' medical insurance， residents' medical insurance group had worse compliance with repeated screening （OR=0.76， 95%CI： 0.66‒0.87）. People with a history of intestinal polyps were more likely to undergo repeat screening than those without （OR=2.07， 95%CI： 1.50‒2.87）. ConclusionCompliance with repeated screening for colorectal cancer still needs to be improved， and there are differences in compliance with repeated screening for different populations with different characteristics. Identifying groups that are unlikely to adhere to community-based colorectal cancer screening and taking targeted interventions can help improve the continued compliance of residents with colorectal cancer screening.

Objective:To explore the value of REG3α,sST2 and TNFR1 in peripheral blood for risk stratification and prognostic evaluation of acute graft-versus-host disease(aGVHD)after allogeneic hematopoietic stem cell transplantation(allo-HSCT)in children.Methods:From January 2020 to March 2022,70 children with aGVHD after allo-HSCT in the First Affiliated Hospital of Zhengzhou University were selected as the research objects,of which 50 cases were mild aGVHD(grade Ⅰ-Ⅱ)and 20 cases were severe aGVHD(grade Ⅲ-Ⅳ).30 healthy children who underwent physical examinations in our hospital during the same period were selected as the control group.Luminex platform was used to detect the protein expression levels of REG3α,sST2 and TNFR1 during aGVHD occurrence,and the differences between the three groups were analyzed by one-way ANOVA.According to the outcome of aGVHD treatment within 28 days,the patients were divided into a good prognosis group of 58 cases and a poor prognosis group of 12 cases.The ROC curve was used to analyze the value of REG3α,sST2 and TNFR1 in predicting the prognosis of children with aGVHD.Results:The peripheral blood levels of REG3α,sST2 and TNFR1 in the mild aGVHD and severe aGVHD groups were significantly higher than those in the control group(P＜0.05),and those in the severe aGVHD group were significantly higher than those in the mild aGVHD group(P＜0.05).Compared with the good prognosis group,the peripheral blood levels of REG3α,sST2 and TNFR1 in the poor prognosis group were significantly higher(t=9.27,3.33,2.97;P＜0.01).ROC curve analysis showed that the area under the curve(AUC),sensitivity and specificity of the combined detection of REG3α,sST2 and TNFR1 in predicting the prognosis of children with aGVHD were higher than those of the above indicators detected alone or in pairs.Conclusion:The expression levels of REG3α,sST2 and TNFR1 were related to the severity of aGVHD.The combination of REG3α,sST2 and TNFR1 has a high clinical value in predicting the prognosis of children with aGVHD,which is expected to provide a reliable reference for clinical evaluation of the prognosis of children with aGVHD.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Aim To explore the effect of γ-ray on the mRNA,protein expression levels and metabolic activity level of the key drug metabolic enzyme CYP3A1 in rat liver. Methods Wistar rats were randomly divided into control group, 24 h post-radiation group and 72 h post-radiation group. The experimental group was exposed to total body irradiation of single 6 Gy γ-ray. Blood was collected from the orbital venous plexus for blood routine examination and biochemical analysis 24 h and 72 h after irradiation, and liver tissue was prepared for quantifying expression of CYP3A1 mRNA and liver-specific microRNA (miR-122-5p) through RT-PCR. The expression level of CYP3A1 protein was analyzed by Western blot, and the metabolic activity level of CYP3A1 detected by the specific substrate midazolam combined with LC-MS method. Results Com¬pared with the control group, the weights of the rats in the radiation group significantly decreased, and the number of white blood cells was markedly reduced. Simultaneously, the activities of alanine aminotrans-ferase and alkaline phosphatase continuously descended, as well as the levels of total bilirubin and bile acid significantly increased, which indicated that the liver may be damaged after radiation. The relative expression of CYP3A1 mRNA continued to increase significantly 24 h and 72 h after irradiation. CYP3A1 protein expression and metabolic activity levels showed an obvious increasing trend 24 h after irradiation, and rose significantly 72 h after irradiation compared with the control group. At the same time, the expression of miR-122-5p in liver of rats in the 24 h and 72 h post-radiation group continued to decrease rapidly compared with the control group. Conclusions γ-ray radiation may arouse damage effect on liver, which leads to the continuous up-regulation of the mRNA and protein expression levels of the capital metabolic enzyme CYP3A1 in liver tissue, as well as the elevation of the metabolic activity level. The regulatory mechanism might be related to miR-122-5p.

The root of Scutellaria baicalensis Georgi, also called Huangqin, is frequently used in traditional Chinese medicine. In ancient China, S. baicalensis root was used to clear heat, protect the fetus, and avoid a miscarriage for thousands of years. In modern times, pregnancy-related diseases can seriously affect maternal and fetal health, but few systematic studies have explored the mechanisms and potential targets of S. baicalensis root in the treatment of pregnancy-related diseases. Flavonoids (baicalein, wogonin and oroxylin A) and flavonoid glycosides (baicalin and wogonoside) are the main chemical components in the root of S. baicalensis. This study presents the current understanding of the major chemical components in the root of S. baicalensis, focusing on their traditional uses, potential therapeutic effects and ethnopharmacological relevance to pregnancy-related disorders. The mechanisms, potential targets and experimental models of S. baicalensis root for ameliorating pregnancy-related diseases, such as recurrent spontaneous abortion, preeclampsia, preterm birth, fetal growth restriction and gestational diabetes mellitus, are highlighted.

Puerarin has the anti-Alzheimer's disease (AD) activity,which can reverse nerve injury induced by Aβand inhibit neuronal apoptosis.However,its potential pharmacodynamic mechanism still needs to be further researched.The occurrence and development of AD is due to the change of multiple metabolic links in the body,which leads to the destruction of balance.Puerarin may act on multiple targets and multiple metabolic processes to achieve therapeutic purposes.Quantitative proteomic analysis provides a new choice to understand the mechanism as completely as possible.This research adopted SH-SY5Y cells induced by Aβ_(1-42)to establish AD cell model,and Aβimmunofluorescence detection showed that Aβdecreased significantly after puerarin intervention.The mechanism of puerarin reversing SH-SY5Y cell injured by Aβ_(1-42)was further explored by using label-free non-labeled quantitative technology and Western blot detection based on bioinformatics analysis result.The results showed that most of the differential proteins were related to biological processes such as cellular component organization or biogenesis,cellular component organization and cellular component biogenesis,and they mainly participated in the top ten pathways of P value such as pathogenic Escherichia coli infection,m TOR signaling pathway,regulation of autophagy,regulation of actin cytoskeleton,spliceosome,hepatocellular carcinoma,tight junction,non-small cell lung cancer,apoptosis and gap junction.Annexin V/PI flow cytometry and TUNEL were used to detect apoptosis,and the results showed that Aβdecreased significantly and the rate of apoptosis decreased significantly after puerarin intervention.Western blot analysis found that the protein expression level of autophagy related protein LC3Ⅱwas up-regulated after Aβinduction,and the degree of this up-regulation was further enhanced in puerarin intervention group.The trend of the ratio of LC3Ⅱ/LC3Ⅰamong groups was the same as the protein expression level of LC3Ⅱ，the protein expression level of p62 in the control group,AD model group and puerarin intervention group decreased successively.Protein interaction network analysis showed that CAP1 was correlated with TUBA1B,HSP90AB2P,DNM1L,TUBA1A and ERK1/2,and the correlation between CAP1 and ERK1/2 was the highest among them.Western blot showed that the expressions of p-ERK1/2,Bax and CAP1 were significantly down-regulated and the protein expression level of Bcl-2 was significantly up-regulated after puerarin intervention.Therefore,puerarin might improve the SH-SY5Y cells injured by Aβ_(1-42)through the interaction of multiple biological processes and pathways in cells multiple locations,and CAP1 might play an important role among them.

OBJECTIVE: To study the epidemiologic characteristics of human herpes virus (HHV) activated infection in the diseases of blood system and patients received allo-HSCT by statistically analyzing the screening results of 8 human herpes viruses (HHVs) of 4164 patients in Hebei Yanda LU Dao-Pei Hospital from 2012 to 2017. METHODS: PCR was used to screen 8 HHVs. RESULTS: Two thousand and fifty-two patients (49.28%) were HHV-positive among 4164 patients screened. Among these patients screened, the infection spectra of 8 human HHVs in hematological diseases as well as patients received allogeneic hematopoietic stem cell transplantation of totally 2994 patients were summarized as follows: the positive rate of EBV (29.49%) was the highest, that of HCMV (23.15%), HHV-6 was 18.77% and HHV-7 was 17.64%, while the remaining 4 HHVs all≤2.1%. The rate of co-infection of various HHVs was significantly higher than that of single infection of HHV among all these disease groups except familial hemophagocytic lymphohistiocytosis, for which single EBV infection was the most common. The differences of positive rates among these 8 human HHVs in hematological diseases as well as patients received allogeneic hematopoietic stem cell transplantation were statistically significant by Chi-square test of R*C tables (χ=54.99, P＜0.05). For each HHV, the differences of positive rates among the above-mentioned disease groups were also statistically significant except HHV-8 (P＜0.05). CONCLUSION The patients with various blood diseases have different activated infection spectra of HHVs. EBV, HCMV, HHV-6 and HHV-7 are most common in HHVs infection. Different HHVs infections correlate with different hematologion diseases.

OBJECTIVE: To investigate apoptotic effects of berberine, a significant alkaloids component existing in Rhizoma coptidis, and its possible acting mechanism in insulinoma cells. METHODS: Different concentrations of berberine were used to treat mouse insulinoma (MIN6) cells for various period of time. The viability and apoptosis of the cells were analyzed using methylthiazolyldiphenvl-tetrazolium bromide assay, flow cytometry and enzyme-linked immuno sorbent assay. Changes in the relating pro- and anti-apoptosis proteins were detected by western-blotting. RESULTS: The half-maximal inhibitory concentration (IC) of berberine was 5.7 μmol/L on MIN6 cells viability for 16 h. Berberine caused a 20% reduction (P<0.05) in cell number after only 4-h incubation; which reached 50% after 24 h (P<0.01). Berberine treatment for 16 h significantly increased the level of DNA fragmentation. The flow cytometry showed the apoptotic rate increased 2.9- and 4.6-fold after treating with berberine (5 μmol/L) for 8 and 16 h, while 3- and 8.7-fold after 10 μmol/L treatment for 8 and 16 h (P<0.01). Berberine treatment dramatically elevated the expression ratio of Bax to Bcl-2. Meanwhile, berberine notably increased the apoptosis-inducing factors and cytochrome C transforming from the mitochondria to the cytoplasm. Apoptotic protease-activating factor 1 (Apaf-1) was subsequently activated after cytochrome C release. Furthermore, caspase-3 and poly adenosine diphosphate-ribose polymerase were also activated to trigger apoptosis cascade. CONCLUSION High concentration (5 and 10 μmol/L) of berberine could induce the apoptosis of MIN6 cells through cytochrome C/Apaf-1/caspase-3 and apoptosis inducing factor (AIF) pathway.

Objective·To analyze the basic medical insurance policies for children in Shanghai in 2011 and 2017, and compare with those of the other three municipalities to understand the basic medical security status of children in four municipalities in China and analyze the existing problems. Methods?·?The current effective children's basic medical insurance policies and child critical illness insurance policies and related insurance systems in four municipalities were collected systematically. The types of basic medical insurance for children in various municipalities and their funding standards, their own expenses and the proportion of government subsidies, the proportion of outpatient emergency payoff lines and reimbursement at all levels of medical institutions, and the coverage and coverage of major illness insurance reimbursement were collected and compared mainly. Results?·?The basic medical insurance for children in Shanghai is a "double insurance" system, which contained children's hospitalization fund and basic medical insurance for urban and rural residents. The basic medical insurance for children in other municipalities mainly consisted of basic medical insurance for urban (rural) residents. Compared with 2011, the level of financing and the reimbursement of the basic medical insurance for urban and rural residents and of the children's hospitalization fund in Shanghai in 2017 was increased. In 2017, the level of financing of basic medical insurance for urban and rural residents in Shanghai was 1?100 yuan, which was slightly lower than that of Beijing medical insurance for urban residents and new rural cooperative medical insurance and was higher than that of basic medical insurance for urban and rural residents in Tianjin and Chongqing, and the individual payment level of Shanghai was the lowest. The hospitalization payoff lines in Shanghai were lower than those of other municipalities. Shanghai's outpatient and inpatient reimbursement levels were higher those of than other municipalities. There wasn't a capping line in Shanghai. There were capping lines in other municipalities. There was a great difference in the insurance policy of the major diseases in four municipalities. Conclusion?·?According to their own actual conditions, models for children's medical care systems that suited each municipalities’ social and economic development have been established. Shanghai children's basic medical insurance basically meets the needs of children's growth but needs improvement in terms of the type and level of medical security for major illnesses.
