BACKGROUND:For elderly patients with traumatic hip fractures,the related factors of prognosis are very complex,and the integrity of the lateral wall is one of the influencing factors.It is of important clinical value to understand the effect of lateral wall injury on the prognosis of femoral intertrochanteric fracture. OBJECTIVE:To evaluate the relationship between the integrity of the lateral wall and hip functional recovery and other outcomes in patients with femoral intertrochanteric fractures. METHODS:Totally 82 patients with femoral intertrochanteric fractures were screened and all patients received proximal femoral nail antirotation fixation.According to the thickness of the lateral wall,the patients were divided into the lateral wall intact group(n=31)and lateral wall risk group(n=51).The perioperative indexes,weight-bearing time,fracture healing time,hip joint function and range of motion,postoperative pain and complications were compared between the two groups. RESULTS AND CONCLUSION:(1)The time of hospitalization and the number of fluoroscopies during operation in the lateral wall intact group were significantly lower than those in the lateral wall risk group(P<0.05),but there was no significant difference in other perioperative indexes.(2)Both groups were able to get down to the ground early after surgery and finally complete weight-bearing,but in the lateral wall risk group,the time of fracture healing was longer;the time of complete weight-bearing was significantly delayed;the Harris score of the last follow-up was lower;the range of motion of hip extension and flexion and neck trunk angle on the affected side were smaller(P<0.05).(3)There was no significant difference in the incidence of postoperative complications between the two groups,but the overall incidence of complications in the lateral wall intact group was significantly lower(P<0.05).(4)In summary,after internal fixation of proximal femoral nail antirotation,patients with the intact lateral wall had a relatively better prognosis than those with risk lateral wall.

Objective:This study aims to explore the expression of miR-143 in gallbladder cancer tissues and its correlation with tumor angiogenesis, clinicopathologic features and clinical prognosis.Methods:The clinical and pathological data of 78 patients with gallbladder cancer who were surgically resected and pathologically confirmed from January 2008 to June 2016 in the Department of General Surgery, Xuancheng Hospital Affiliated to Wannan Medical College were collected, including 20 males and 58 females, with an average age of (68.0±1.4) years. 78 cases of gallbladder cancer tissue were used as the tumor group, and 32 cases of normal gallbladder tissue adjacent to cancer were randomly selected as the control group. The expression level of miR-143 in the tumor group and the control group was detected by in situ hybridization. Microvessel density (MVD) were evaluated with immunohistochemistry to detect the expression of CD34 in tumor group. The expression of miR-143 and its correlation with tumor MVD, pathological characteristics and prognosis were analyzed by Cox regression analysis.Results:The results of in situ hybridization showed that the positive rate of miR-143 in gallbladder cancer tissues and average expression score were significantly lower than those in adjacent normal gallbladder tissues [29.49% (23/78) vs 62.5% (20/32), χ 2=10.39, P=0.001; (2.705±0.172) vs (4.688±0.405), t=5.33, P<0.001]. Correlation analysis showed that the expression of miR-143 was associated with lymph node metastasis of gallbladder cancer ( P=0.036). The MVD counts in the miR-143 positive group were significantly lower than those in the miR-143 negative group [(126.2±8.483) vs (157.4±6.412), t=2.75, P=0.007)]. The median survival time of gallbladder cancer patients with miR-143 positive and negative was 16 and 9 months, respectively. Cox regression analysis showed that the low expression of miR-143 was an independent risk factor affecting the clinical prognosis of gallbladder cancer. Conclusion:The expression of miR-143 is down-regulated in gallbladder cancer and participates in angiogenesis and clinical prognosis of gallbladder cancer.

Objective:To develop a nomogram to predict the probability of prostate cancer after transeperineal prostate biopsy, and verify the diagnostic efficacy and clinical applicable value of the model.Methods:The clinicopathologic data of 475 patients who underwent prostate biopsy at Yijishan Hospital of Wannan Medical College between January 2019 to August 2021 were retrospectively reviewed. Of all the patients, 367 patients from January 2019 to December 2020 were in the development cohort and 108 patients from January 2021 to August 2021 were in the validation cohort. Patients in the development cohort were (68.86±9.00) years old. The tPSA level was 13.6(8.6, 23.3)ng/ml, and Prostate Imaging Reporting and Data System (PI-RADS) score was 4(3, 4) points. Patients in the validation cohort were (68.89±8.67) years old. The tPSA was 13.1(8.7, 25.6)ng/ml, and PI-RADS score was 4 (3, 5) points. Univariate and multivariate logistic regression were used to analyze prostate cancer risk factors in the development cohort. Then the nomogram prediction model was established by the risk factors. The prediction model's performance was evaluated using receiver operating characteristic (ROC) curves, calibration maps, and decision curve (DCA) analysis in the development cohort. The performance of the model was verified in the validation cohort.Results:The pathological results showed 180 patients with prostate cancer and 187 patients without prostate cancer in the development cohort. The validation cohort included 53 patients with and 55 without prostate cancer. Based on the results of the univariate and multivariate logistic regression analysis, this model incorporates factors including age ( OR=1.059, P=0.003), platelet-to-monocyte ratio (PMR) ( OR=0.002, P=0.011), f/tPSA ( OR=0.009, P=0.020), and PI-RADS score ( OR= 3.076, P<0.001). The calibration curve revealed a great agreement. Internal validation of the nomogram showed that the area under the ROC curve was 0.845 (95% CI 0.794-0.895). The Hosmer-Lemeshow test was also performed( χ2=1.476, P=0.224). The validation group with an area under the ROC curve was 0.869 (95% CI 0.797-0.941). The results of the decision curve analysis indicated that the decision curve was located above the positive and negative lines in the threshold range of 10% to 90%, within which the model has clinical application. Conclusions:The nomogram, which combines patient age, PMR, f/t PSA, and PI-RADS scores, has high predictive efficacy for prostate cancer and has clinical application value.

Objective:To analyze the changing trend of intracerebral hemorrhage (ICH) incidence among residents with different characteristics during 9 years of comprehensive hypertension prevention and control (hypertension prevention and control) in Tengzhou from 2013 to 2021.Methods:From January 1, 2013 to December 31, 2021, the new ICH cases collected by the Center for Disease Control and Prevention in Tengzhou City were analyzed to calculate the incidence of ICH, and the trend of its distribution was analyzed among residents with different ages, sexes, and between urban and rural areas. The registered population information came from Tengzhou Public Security Bureau. Age and sex standardized incidence was calculated based on the 7th National Population Census in 2020. The Cochran-Armitage test was used to analyze the time and age trends of the incidence.Results:The overall ICH crude and standardized incidence in Tengzhou City decreased from 97.30/100 000 to 52.13/100 000 ( Z=-9.93, P<0.001) and 119.30/100 000 to 50.69/100 000 ( Z=-15.40, P<0.001) from 2013 to 2021, and both elevated to form a single peak in 2020, with 22.58% ( χ 2=24.02, P<0.001) and 18.09% ( χ 2=17.08, P<0.001) higher than in 2019, respectively. The trends in male and female incidence over the same period were similar to the overall trends, and the incidence was higher in males than in females in all years. The incidence of ICH increased with age in all years. The difference of increase in male incidence rate in 2020 was statistically significant in three age groups ≥45 years compared with 2019 (36.29%, 23.57% and 16.18%, respectively, χ 2=6.73, 4.65, 4.00, P<0.001). The incidence of ICH decreased by 70.07% and 36.23% ( Z=18.44, 5.22, P<0.001) in urban and rural areas respectively from 2013 to 2021, whereas increased by 34.15% ( χ 2=10.88, P<0.01) and 22.08% ( χ 2=18.63, P<0.001) in 2020 compared with 2019 separately. Conclusions:The incidence of ICH in Tengzhou from 2013 to 2021 showed a significant downward trend, with the decrease in the incidence of ICH in women exceeding that in men. The decrease in the incidence of ICH in urban areas exceeded that in rural areas, and male morbidity seemingly had a younger trend.

Objective@#To examine the association between secondhand smoke exposure (SHS) in indoor public places and carotid intima media thickness (cIMT) in children and adolescents, so as to provide guidance for the prevention of early abnormal vascular architecture.@*Methods@#The data were obtained from the second follow up of the Children Cardiovascular Health Cohort Study conducted from November to December 2021. A total of 1 297 children and adolescents for who completed data relating to sex, age, cIMT, physical examinations, questionnaires variables and blood biochemical indices, were included for analysis. Linear regression analysis was performed to examine trends in the levels of cIMT with exposure to SHS in indoor public places. Multiple linear regression analysis was carried out to assess the association between SHS exposure in indoor public places and cIMT after adjustment for potential covariates.@*Results@#During the previous 7 days, 407 (31.4%) children and adolescents were exposed to SHS in indoor public places for 1-2 days, 86 (6.6%) for 3-4 days, and 82 (6.3%) for ≥5 days. The levels of cIMT in youth increased on different models, with the duration of SHS exposure during the previous 7 days ( t=3.30, 3.05, 2.87, P <0.05). After adjusting for various covariates, the cIMT values of children and adolescents were[0 day:(551.5±29.3) μm, 1-2 days:(554.0±28.6) μm, 3-4 days:(557.0±27.7) μm, ≥5 days:(559.4±27.5) μm]. Compared to those who were not exposed to SHS in indoor public places during the previous 7 days, those exposed for ≥5 days had significantly higher cIMT levels ( β=7.91, 95%CI=1.47-14.34, P <0.05).@*Conclusion@#Among children and adolescents, exposure to SHS in indoor public places remains high and is significantly associated with cIMT. The findings highlight the need for stricter regulation and tobacco control policies to provide healthy smoke free environments for children and adolescents, and to reduce the risk of early abnormal vascular architecture.

Objective@#To examine the association between secondhand smoke (SHS) exposure in indoor public places and sleep deprivation, so as to provide a reference for strengthening the management of a smoking ban in public places and to promote better sleep in childhood.@*Methods@#Data were obtained from the second follow up survey of the Huantai Childhood Cardiovascular Health Cohort Study, which was conducted from November to December 2021. A total of 1 284 children aged 10-15 years old were included in the study. The participants were assigned to four groups (0, 1-2, 3-4 and ≥5 days) according to the frequency which they were exposed to SHS in indoor public places in the previous 7 days. Multiple linear regression was performed to examine the trend of children s sleep duration with the frequency of SHS exposure. Multivariate Logistic regression was carried out to determine the association between frequency of SHS and sleep deprivation.@*Results@#After adjusting for age, sex, grade, physical activity, intake of fruits/vegetables, intake of soft drinks, screen duration, body mass index (BMI) and blood pressure, the average sleep duration of children who were exposed to SHS for 0, 1-2, 3-4 and ≥5 days in the previous 7 days was 8.48, 8.41, 8.20 and 8.06 h/d , respectively, and the average sleep duration decreased with exposure frequency of SHS ( t=5.96, 5.89, 5.91, P < 0.01 ). The proportion of sleep deprivation among children who were exposed to SHS in public places for 0, 1-2, 3-4 and ≥5 days in the previous 7 days was 40.02%, 43.07%, 54.65% and 63.41%, respectively. Compared to children who were not exposed to SHS in indoor public places in the past 7 days, those exposed for 3-4 days ( OR=1.93, 95%CI =1.19-3.15) or ≥ 5 days ( OR=2.95, 95%CI = 1.76- 4.94) had a significantly increased risk of sleep deprivation ( P <0.05).@*Conclusion@#Children s sleep time decreases with increasing frequency of exposure to SHS, and children who are frequently exposed to SHS are more likely to experience insufficient sleep. Smoking ban management in public places should be strengthened to promote children s sleep health, especially indoor public places.

@#Introduction: During the COVID-19 pandemic, healthcare providers have been in great fear due to the high risk of contracting COVID-19 infection at any time. This study aimed to determine the mediating role of resilience on the relationship between fear of COVID-19 and burnout in primary care healthcare providers in Malaysia. Methods: This was an online cross-sectional study involving 1280 healthcare providers aged 18 years and older from 30 government primary care clinics in Malaysia. We used the COVID-19 Fear Scale, the Copenhagen Burnout Inventory Scale, and the Short Brief Resilience Scale to collect data from the respondents. Smart-PLS was used to perform mediation analysis. Results: The mean age of the respondents was 36 years old and mean duration of working experience was 11 years. The majority of the respondents were female (82.4%) and Malays (82.3%). The study population consisted of nurses (47.4%), doctors (26%), medical assistants (11.9), healthcare assistant (7.1%), medical laboratory technicians (6.4%) and drivers(1.3).The results show that fear of COVID-19 positively predicts burnout. According to the results, resilience mediates the relationship between fear of COVID-19 and all the three burnout domains, namely personal burnout (β=0.175,p<0.001), work-related burnout (β=0.175,p<0.001) and client-related burnout (β=0.172,p<0.001). Additionally, resilience reduces the impact of COVID-19 fear on the three domains of burnout. Conclusion: Our study has reported a mediating effect of resilience on the relationship between fear of COVID-19 and burnout.

Background/Aims@#Stigma related with antidepressants is prevalent in patients with functional dyspepsia. It affects medication compliance and efficacy.Herbal medicine acquired a deep-rooted cultural identity in relieving dyspeptic symptoms in Asians. The research was designed to compare the effectiveness of Zhizhu Kuanzhong capsules (ZZKZ) versus doxepin hydrochloride (doxepin) on alleviating stigma and medication nonadherence among patients with refractory FD (rFD). @*Methods@#Patients with rFD from February 2021 to February 2022 were randomly allocated to receive either doxepin (n = 56) or ZZKZ (n = 57) combined with omeprazole for 4 weeks. Medication possession ratio (MPR), the disease- and medication-associated stigma were analyzed. The scales were utilized to assess dyspeptic symptoms (Leeds Dyspepsia Questionnaire) and psychological conditions (Generalized Anxiety Disorder Questionnaire and Patient Health Questionnaire). @*Results@#The MPR values for ZZKZ were significantly higher than those for doxepin (P < 0.001). The stigma scores decreased in ZZKZ group while increased in doxepin group compared to baseline after treatment. The proportion of patients showing ZZKZ-associated stigma was significantly lower than doxepin-associated stigma (P < 0.001). The MPR values were negatively correlated with posttreatment stigma scores in both groups (P < 0.001). Dyspeptic symptoms and psychological condition were improved in both groups after treatment, with no significant difference on post-treatment Leeds Dyspepsia Questionnaire, Generalized Anxiety Disorder Questionnaire, or Patient Health Questionnaire scores between 2 groups. @*Conclusion@#ZZKZ is superior to doxepin in alleviating stigma and medication non-adherence, with comparable efficacy in improving dyspeptic symptoms and psychological condition of patients with rFD.

Objective@#Individuals with dementia are at a substantially elevated risk for mortality; however, few studies have examined multimorbidity patterns and determined the inter-relationship between these comorbidities in predicting mortality risk. @*Methods@#This is a prospective cohort study. Data from 6,556 patients who were diagnosed with dementia between 1997 and 2012 using the Taiwan National Health Insurance Research Database were analyzed. Latent class analysis was performed using 16 common chronic conditions to identify mortality risk among potentially different latent classes. Logistic regression was performed to determine the adjusted association of the determined latent classes with the 5-year mortality rate. @*Results@#With adjustment for age, a three-class model was identified, with 42.7% of participants classified as “low comorbidity class (cluster 1)”, 44.2% as “cardiometabolic multimorbidity class (cluster 2)”, and 13.1% as “FRINGED class (cluster 3, characterized by FRacture, Infection, NasoGastric feeding, and bleEDing over upper gastrointestinal tract).” The incidence of 5-year mortality was 17.6% in cluster 1, 26.7% in cluster 2, and 59.6% in cluster 3. Compared with cluster 1, the odds ratio for mortality was 9.828 (95% confidence interval [CI]=6.708–14.401; p<0.001) in cluster 2 and 1.582 (95% CI=1.281–1.953; p<0.001) in cluster 3. @*Conclusion@#Among patients with dementia, the risk for 5-year mortality was highest in the subpopulation characterized by fracture, urinary and pulmonary infection, upper gastrointestinal bleeding, and nasogastric intubation, rather than cancer or cardiometabolic comorbidities. These findings may improve decision-making and advance care planning for patients with dementia.

@#Abstract: Objective Quantitative assessment of risk factors of clonorchiasis can provide prevention for clonorchiasis. Methods Articles were retrieved in Chinese and English electronic databases from January 1, 2000 to December 31, 2020, including Wanfang Data, CNKI, PubMed, Web of Science, Embase. All studies were screened based on inclusion and exclusion criteria, and the quality of all enrolled literatures was evaluated. The software RevMan version 5.3 was used for Meta-analysis. The heterogeneity, sensitivity and publication bias of all included studies were analyzed. Results A total of 95 articles were retrieved, and 6 were included in this Meta-analysis which were case-control studies. There were 5 articles in Chinese and 1 in English. There was no single literature with a large impact on the results, and the results of this study were relatively stable. There were 1 170 cases of clonorchiasis in total and 1 291 cases in control. Most of the cases were from hospital patients and community residents, and the floating population was small. Meta-analysis showed that there were three independent risk factors: raw or semi-raw fish, raw or semi-raw shrimp, mix raw and cooked cutting boards, with a combined OR (95%CI) of 2.32(1.86, 2.88), 3.99(2.42, 6.58), 2.18(1.51, 3.14), respectively, with low heterogeneity consistent with the results of the total sample study: I2 values for risk factors were 30%, 12%, 27%, respectively. The results of bias tests showed no publication bias (P=0.731, 0.725, 0.334, P>0.05). Conclusions The key risk factors of clonorchiasis are raw or semi-raw fish, raw or semi-raw shrimp, mix raw and cooked cutting boards. Guidance and health education should be strengthened. It is necessary to strengthen the surveillance of clonorchiasis in the floating population, such as traveler, businessman and student.

@#Abstract: Objective To investigate the pollution of paralytic shellfish poisons (PSP) in shellfish sold in Hainan Province from 2018 to 2021. Methods From 2018 to 2021, the content of 10 paralytic shellfish poisons including saxitoxin (STX), neosaxitoxin (neoSTX), gonyautoxins 1 (GTX1), gonyautoxins 2 (GTX2), gonyautoxins 3 (GTX3), gonyautoxins 4 (GTX4), gonyautoxins 5 (GTX5), decarbamoylsaxitoxin (dcSTX), decarbamoylgonyau toxins 2 (dcGTX2) and decarbamoylgonyau toxins 3 (dcGTX3) in 7 kinds of shellfish commonly sold in 13 cities and counties in Hainan province was analyzed. Results The detection rate of PSP in 360 shellfish samples was 10.3%. Among them, the highest detection rate of STX was 5.83%, followed by GTX2 detection rate of 4.17%; the detection rate of neoSTX and GTX3 were both 1.67%; the detection rate of GTX1 was 1.39%. None of the five PSP, GTX4, GTX5, dcSTX, dcGTX2 and dcGTX3, were detected. Four types of PSP were detected in fanscallops, two were detected in oysters, mussels and Scapharca subcrenata, only one was detected in scallops, and no toxin contamination was detected in clams and razor clams. A single sample of fanscallops detected a maximum of 4 PSP, and a single sample of oysters, scallops, mussels and Scapharca subcrenata detected a maximum of 1 PSP. The equivalence of PSP in all samples was ND-155.6 μg/kg.The annual detection rate of PSP from high to low was: 20.0% in 2020, 15.6% in 2019, 5.3% in 2018, and 2.0% in 2021, and none of the samples tested exceeded the standard. Continuously detectable STX in 2018-2020, all PSP that could be detected in 2018 were STX. In 2019, in addition to STX detected in scallops and Scapharca subcrenata, neoSTX was also detected in oysters, mussels and Scapharca subcrenata. In 2020, PSP was only detected from scallops, and GTX2 could be detected in all positive specimens, while 5 STX, 5 GTX1 and 6 GTX3 were detected. Only GTX2 detected from scallops in 2021. STX was detected in shellfish sold in 12 cities and counties, GTX2 can be detected in 10 cities and counties, neoSTX can be detected in 5 cities and counties, GTX1 and GTX2 were detected in 4 cities and counties respectively. Shellfish sold in Wenchang and Lingshui markets can detect 5 types of PSP. Conclusion Some types of shellfish on the market in Hainan are contaminated with some kind of PSP pollution risks, and it is necessary to strengthen the supervision of PSP in marketed shellfish.

Objective: To compare the effects and safety of dydrogesterone (DG) and medroxyprogesterone acetate (MPA) on the treatment in patients with endometrial hyperplasia without atypia (EH). Methods: This was a single-center, open-label, prospective non-inferior randomized controlled phase Ⅲ trial. From February 2019 to November 2021, patients with EH admitted to the Obstetrics and Gynecology Hospital of Fudan University were recruited. Enrolled patients were stratified according to the pathological types of simple hyperplasia (SH) or complex hyperplasia (CH), and were randomised to receive MPA or DG. Untill May 14, 2022, the median follow-up time after complete response (CR) was 9.3 months (1.1-17.2 months). The primary endpoint was the 6-month CR rate (6m-CR rate). The secondary endpoints included the 3-month CR rate (3m-CR rate), adverse events rate, recurrence rate, and pregnancy rate in one year after CR. Results: (1) A total of 292 patients with EH were enrolled in the study with the median age of 39 years (31-45 years). A total of 135 SH patients were randomly assigned to MPA group (n=67) and DG group (n=68), and 157 CH patients were randomly assigned to MPA group (n=79) and DG group (n=78). (2) Among 292 patients, 205 patients enrolled into the primary endpoint analysis, including 92 SH patients and 113 CH patients, with 100 patients in MPA group and 105 in DG group, respectively. The 6m-CR rate of MPA group and DG group were 90.0% (90/100) and 88.6% (93/105) respectively, and there were no statistical significance (χ2=0.11, P=0.741), with the rate difference (RD) was -1.4% (95%CI:-9.9%-7.0%). Stratified by the pathology types, the 6m-CR rate of SH patients was 93.5% (86/92), and MPA group and DG group were respectively 91.1% (41/45) and 95.7% (45/47); and the 6m-CR rate of CH patients was 85.8% (97/113), and MPA group and DG group were 89.1% (49/55) and 82.8% (48/58) respectively. The 6m-CR rates of the two treatments had no statistical significance either (all P>0.05). A total of 194 EH patients enrolled into the secondary endpoint analysis, including 88 SH patients and 106 CH patients, and 96 patients in MPA group and 98 in DG group, respectively. The 3m-CR rate of SH patients were 87.5% (77/88), while the 3m-CR rates of MPA group and DG group were 90.7% (39/43) and 84.4% (38/45), respectively; the 3m-CR rate of CH patients was 66.0% (70/106), and MPA group and DG group had the same 3m-CR rate of 66.0% (35/53). No statistical significance was found between the two treatments both in SH and CH patients (all P>0.05). (3) The incidence of adverse events between MPA group and DG group had no statistical significance (P>0.05). (4) A total of 93 SH patients achieved CR, and the cumulative recurrence rate in one year after CR were 5.9% and 0 in MPA group and DG group, respectively. While 112 CH patients achieved CR, and the cumulative recurrence rate in one year after CR were 8.8% and 6.5% in MPA group and DG group, respectively. There were no statistical significance between two treatment groups (all P>0.05). Among the 93 SH patients, 10 patients had family planning but no pregnancy happened during the follow-up period. Among the 112 CH patients, 21 were actively preparing for pregnancy, and the pregnancy rate and live-birth rate in one year after CR in MPA group were 7/9 and 2/7, while in DG group were respectively 4/12 and 2/4, and there were no statistical significance in pregnancy rate and live-birth rate between the two treatment groups (all P>0.05). Conclusions: Compared with MPA, DG is of good efficacy and safety in treating EH. DG is a favorable alternative treatment for EH patients.

Objective: To investigate the effect of nuclear factor erythroid 2-related factor 2 (Nrf2) in the alteration of tight junction protein expression in choroid plexus epithelial cells created by lanthanum-activated matrix metalloproteinase 9 (MMP9) . Methods: In October 2020, immortalized rat choroid plexus epithelial cell line (Z310) cells were used as the blood-cerebrospinal fluid barrier in vitro, and were divided into control group and 0.125, 0.25, 0.5 mmol/L lanthanum chloride (LaCl(3)) treatment group. After treating Z310 cells with different concentrations of LaCl(3) for 24 hours, the morphological changes of Z310 cells were observed under inverted microscope, the protein expression levels of MMP9, occludin and zonula occludens-1 (ZO-1) were observed by cellular immunofluorescence method, and the protein expression levels of MMP9, tissue inhibitors of metalloproteinase1 (TIMP1) , occludin, ZO-1 and Nrf2 were detected by Western blotting. The level of reactive oxygen species (ROS) in cells was detected by flow cytometry. Results: Compared with the control group, Z310 cells in the LaCl(3) treatment group were smaller in size, with fewer intercellular junctions, and more dead cells and cell fragments. The expression level of MMP9 protein in cells treated with 0.25 and 0.5 mmol/L LaCl(3) was significantly higher than that in the control group (P<0.05) , and the expression level of TIMP1 and tight junction proteins occudin and ZO-1 was significantly lower than that in the control group (P<0.05) . Compared with the control group, the ROS production level in the 0.25, 0.5 mmol/L LaCl(3) treatment group was significantly increased (P<0.05) , and the Nrf2 protein expression level in the 0.125, 0.25, 0.5 mmol/L LaCl(3) treatment group was significantly decreased (P<0.05) . Conclusion: Lanthanum may increase the level of ROS in cells by down regulating the expression of Nrf2, thus activating MMP9 to reduce the expression level of intercellular tight junction proteins occludin and ZO-1.

Objective:To investigate the temporal trend of the mortality rate of intracerebral hemorrhage (ICH) among residents with different characteristics during the comprehensive prevention and control of hypertension in Tengzhou, Shandong Province from 2013 to 2021.Methods:Comprehensive prevention and control of hypertension was conducted in Tengzhou, Shandong Province from 2013 to 2021. ICH mortality rate was calculated from January 1, 2013 to December 31, 2021. ICH mortality monitoring data from Tengzhou, Shandong Province was used to analyze the temporal trend of ICH mortality among residents with different characteristics. The registered residence population came from the Public Security Bureau of Tengzhou, Shandong Province. The age and gender standardized mortality rate was calculated based on the data of China's seventh population census in 2020. The temporal and age trends of mortality were analyzed using Cochran Armitage Trend Tests.Results:From 2013 to 2021, the overall crude and standardized mortality rates of ICH in Tengzhou, Shandong Province decreased from 50.51/100 000 and 63.21/100 000 to 17.51/100 000 and 16.74/100 000, respectively ( Z=-11.013 and -15.426, P<0.001), with an average annual mortality rate decrease of 12.41% and 15.30%, respectively. The overall crude and standardized mortality rates in 2017 peaked compared to 2016, mainly due to an increase of 32.94% and 30.92% in male ICH crude and standardized mortality rates, respectively ( χ2=12.328 and 15.854, P<0.05). The mortality rate of ICH increased with age, and the decreasing trend over time became increasingly evident with age. The mortality rate of ICH in the ≥65 year old age group decreased by 77.94% over 9 years ( Z=-14.065, P<0.001). In 2017, the mortality rate of ICH in the male age group ≥65 years old and female 45-54 years old increased by 31.13% and 125.79% compared to 2016 respectively, there were statistically significant differences ( χ2=8.877 and 5.421, P<0.05). In 2021, the mortality rates of urban and rural ICH decreased by 93.22% and 46.40% compared to 2013, respectively ( Z=-13.279 and -5.393, P<0.001), with an average annual decrease of 28.56% and 7.50%, respectively. The ICH mortality rate in rural areas increased by 30.54% in 2017 compared to 2016 ( χ2=16.086, P<0.001); after 2018, the mortality rate of ICH began to be higher than that of urban areas ( χ2=33.400 and 67.305, P<0.001). Conclusions:The ICH mortality rate in Tengzhou, Shandong Province has shown a significant downward trend over time, with male mortality rate higher than female mortality rate and rural mortality rate higher than urban areas. This suggests that the key attention should be paid to both male and rural areas.

Objective:To analyzed the urinary microbiota characteristics of upper tract urothelial carcinoma(UTUC) patients.Methods:Urine samples were collected from 23 patients with UTUC (UTUC group) and 22 patients with benign diseases (control group) admitted to Yijishan Hospital, the First Affiliated Hospital of Wannan Medical College from July 2021 to July 2022. The differences in age [(60.9±5.7) years vs. (61.4±8.8) years], sex (male/female: 15/8 vs. 9/13), and body mass index [(22.9±1.8) kg/m 2 vs. (23.4±1.7) kg/m 2] between the UTUC group and the control group were not statistically significant ( P>0.05). The V4 region of the 16S rRNA of urinary microorganisms was sequenced using the Illumina NovaSeq6000, and the results were processed using QLLME2. Differences in α-diversity between groups were analyzed by using the Shannon, Simpson, and Chao1 indices. Differences in β-diversity between groups were analyzed by using unweighted principal coordinates analysis (PCoA). Linear discriminant analysis Effect Size(LEfSe)was used to identify the bacterial taxa with different abundances between groups. Significant differences were defined as LDA>2. Results:The Chao1 index (703.12±265.54 vs. 506.20±214.02) and Shannon index (5.61±1.85 vs. 5.07±1.34) were significantly higher in the UTUC group compared to that in the control group ( P<0.05). The α-diversity of urinary microbes was elevated in the UTUC group compared to that in the control group but the difference in β-diversity was not statistically significant ( P=0.161). The enrichment of Bacteroidaceae, Ruminococcaceae, Acidaminococcaceae, Thermaceae, Erysipelatoclostridiaceae, and Coriobacteriaceae abundance was higher in the urine of UTUC patients(LDA > 2). Further subgrouping analyses of the UTUC patients showed that the differences in Chao1 index (706.44±271.84 vs. 784.09±272.72), Shannon index (6.04±1.30 vs. 5.91±1.67), and Simpson index (0.94±0.08 vs. 0.89±0.22) between the muscle-invasive group and the non-muscle-invasive group were not statistically significant ( P>0.05). The difference in α-diversity between muscle-invasive and non-muscle-invasive group was not statistically significant, but the difference in β-diversity was statistically significant ( P=0.047). The urinary microbial communities of Gammaproteobacteria, Cutibacterium, Rhodococcus and Nocardiaceae were enriched in muscle-invasive group and differed from that in non-muscle-invasive group(LDA>2). Conclusions:This study suggests that the urinary microbial community was more abundant in UTUC patients than in non-UTUC patients and that Bacteroidaceae, Ruminococcaceae, Acidaminococcaceae, Thermaceae, Erysipelatoclostridiaceae, and Coriobacteriaceae were more abundant in the urine of UTUC patients. The urinary microbial community was more abundant in the urine of non-muscle-invasive patients than in the muscle-invasive patients, and Gammaproteobacteria, Cutibacterium, Rhodococcus and Nocardiaceae were more abundant in the urine of non-muscle-invasive patients.
