ABSTRACT
Taking the graduation ceremony of Peking University Health Science Center in 2020 as the observation object, this paper used Collins’ Interactive Ritual Chains Theory to analyze the form, theme and featured part of this ceremony from the dimensions of physical co-presence, barrier to outsiders, joint focus of attention and shared mood. It was found that the ceremony in medical colleges had an impact on the cognition, behavior and spirit of junior medical students in terms of group identity, emotional energy, group symbols and moral sense, which played a good role in professionalism education. Some enlightenment and thinking were obtained on this basis to provide some references for medical colleges to give full play to the educational function of the professionalism in the post-epidemic era.
ABSTRACT
This paper summarized professor LIU Ruifen's clinical experience in treating endometrial hyperplasia. It is believed that the core pathogenesis of endometrial hyperplasia is internal obstruction of uterus and intrauterine collaterals by latent stasis. Based on the clinical manifestations， the menstrual cycle is divided into three stages， that is menstrual period， menstrual leakage period， and clear menstrual period， and the method of “three-staged stasis dispelling” is proposed. During the menstrual period， it is appropriate to move qi and invigorate blood， dissolve stasis and disperse concretions， with self-made Gongqing Formula （宫清方）. For menstrual leakage period， it is suggested to boost qi and clear heat， dispel stasis and stanch bleeding， with self-made Tongyong Zhixue Formula （通用止血方）. In terms of clear menstrual period， the method of dissolving phlegm and dissipating masses， moving qi and dispelling stasis is advised， and self-made Zhitong Tiaoxue Formula （止痛调血方） can be used. Simultaneously， attention should be paid to the combination of syndrome differentiation and disease differentiation， as well as collaborative diagnosis and treatment with traditional Chinese and Western medicine.
ABSTRACT
Objective@#To explore the characteristics and related factors of adolescent executive function, so as to provide theoretical basis for promoting the development of adolescent executive function.@*Methods@#A total of 5 018 adolescents aged 13-18 from Shanghai, Suzhou, Taiyuan, Wuyuan, Xingyi and Urumqi were selected by convenient cluster random sampling method from September to December 2022, and their basic information, family status, lifestyle behavior, physical fitness and executive function were investigated by questionnaire survey. Considering the heterogeneity between schools, a multilevel Logistic model was established to analyze the related factors of adolescent executive function.@*Results@#The inhibitory function of high school students was better than that of middle school students (Z=-2.69). In terms of refreshment function, high school students were superior than middle school students (1-back:Z=-11.32; 2-back:Z=-11.36), and male students were superior than female students (2-back:Z=-2.18); in terms of shifting function, high school students were superior than middle school students (Z=-2.63), and boys were superior than girls (Z=-7.10)(P<0.05). The results of multilevel model analysis showed that the executive function of adolescents was clustered at the school level. At the individual level, junior high school refreshment function (1-back:β=56.94; 2-back:β=127.00), and shifting function (β=35.64) were worse than that of high school students; the refreshment function 2-back (β=-21.24) and shifting function (β=-28.42) of male students were better than those of female students; the refreshment function 2-back of nononly child was better than that of only child (β=-19.36); refreshment function of low fitness was worse than that of high fitness (β=37.35); the shifting function of the video screen time not up to standard was better than that of the standard (β=-14.30)(P<0.05).@*Conclusions@#The executive function of high school students is better than that of middle school students, the refreshment function and shifting function of boys are better than that of girls. Family environment, lifestyle and physical health are significant factors related to executive function of Chinese adolescents. By raising awareness of the major supporting and impeding factors for executive functioning in adolescents, it can help to develop effective intervention programs for adolescents.
ABSTRACT
To understand the progress of national schistosomiasis elimination program of China in 2023 and summarize the lessons and experiences, data on the endemic status of schistosomiasis and national schistosomiasis surveillance results in the People’s Republic of China were collected and analyzed at a national level. By the end of 2023, Shanghai Municipality, Zhejiang Province, Fujian Province, Guangdong Province and Guangxi Zhuang Autonomous Region continued to consolidate the achievements of schistosomiasis elimination, and Sichuan and Jiangsu provinces maintained the criteria of transmission interruption, while Yunnan and Hubei provinces were identified to achieve the criteria of transmission interruption in 2020, and Anhui, Jiangxi and Hunan provinces achieved the criteria of transmission interruption in 2023. A total of 451 counties (cites, districts) were found to be endemic for schistosomiasis in China in 2023, including 26 250 endemic villages covering 73 034 500 residents at risk of infections. Among the 451 endemic counties (cities, districts), 78.49% (354/451) achieved the criteria of schistosomiasis elimination and 21.51% (97/451) achieved the criteria of transmission interruption, respectively. In 2023, a total of 4 216 643 individuals received immunological tests, with 47 794 sero-positives identified, and a total of 184 216 individuals received parasitological examinations, with 4 egg-positives detected. A total of 27 768 cases with advanced schistosomiasis were documented in China by the end of 2023. In 2023, 539 548 bovines were raised in schistosomiasis-endemic areas of China, and 125 440 bovines received immunological tests, with 124 sero-positives detected, while no egg-positives were identified among the 133 508 bovines receiving parasitological examinations. In 2023, snail survey was performed at an area of 641 339.53 hm2 and 184 819.77 hm2 snail habitats were identified, including 51.53 hm2 emerging snail habitats and 642.25 hm2 reemerging snail habitats. In 2023, there were 20 198 schistosomiasis patients receiving praziquantel chemotherapy, and 598 183 person-time individuals and 283 954 herdtime bovines were given expanded chemotherapy. In 2023, snail control with chemical treatment was performed in 116 347.95 hm2 snail habitats, and the actual area of chemical treatment was 65 690.89 hm2, while environmental improvements were performed in snail habitats covering an area of 1 334.62 hm2. The national schistosomiasis surveillance results showed that the mean prevalence of Schistosoma japonicum infections were both zero among humans and bovines in 2023, and no S. japonicum infection was detected in snails. These data demonstrated that transmission interruption of schistosomiasis had been achieved across all endemic provinces in China in 2023, and the endemic status of schistosomiasis tended to be stable, while advanced cases were predominant among all schistosomiasis cases. However, the areas of snail habitats remained high and cattle re-raising was very common in some regions. Intensified schistosomiasis surveillance and forecast and snail control in high-risk areas are needed.
ABSTRACT
Objective:To evaluate the effects of different types of psychological interventions on the fear of cancer recurrence through a network Meta-analysis.Methods:Randomized controlled trials on the effects of different types of psychological interventions on the fear of cancer recurrence were retrieved from PubMed, PsycINFO, Web of Science, The Cochrane Library, Embase, EBSCO, China Biomedical Literature Database, CNKI, Wanfang Database and Vip Database. The retrieval period was from the establishment of the database to December, 31 2022. Two researchers conducted literature screening, extraction and quality evaluation, and used Stata14.0 software to conduct network Meta-analysis.Results:A total of 29 pieces of research involving 3 068 cancer patients and 11 psychological intervention measures. The results of network Meta-analysis showed that narrative therapy, PERMA(Positive, Engagement, Relationship, Meaning, Accomplishment) happiness theory model, acceptance and commitment therapy and cognitive behavior therapy had statistically significant differences in the intervention effect on the fear of cancer recurrence compared with conventional nursing ( SMD values were -1.93--0.83, all P<0.05); there was no significant difference among narrative therapy, PERMA happiness model, acceptance and commitment therapy and gratitude-expansion behavior theory (all P>0.05). The results of the cumulative probability map showed the best intervention was narrative therapy. Conclusions:The results of this study suggest that narrative therapy, acceptance and commitment therapy, and cognitive behavior therapy may be effective psychological intervention measures to improve the fear of cancer recurrence. However, more studies are still needed for further verification.
ABSTRACT
BACKGROUND:N6-methyladenosine(m6A)is a hot research topic in the mechanism of pathological cardiac remodeling and plays an important role in the development of cardiovascular diseases. OBJECTIVE:To summarize the possible mechanism by which m6A modification in non-coding RNAs regulates the main processes of pathological cardiac remodeling,such as pathological cardiac hypertrophy,cardiomyocyte death,myocardial fibrosis and vascular remodeling. METHODS:"m6A,non-coding RNA,pathological cardiac hypertrophy,cardiomyocyte apoptosis,cardiomyocyte pyroptosis,cardiomyocyte ferroptosis,myocardial fibrosis,vascular remodeling"were used as search terms in Chinese and English.Relevant literature from CNKI,PubMed and Web of Science databases published from January 1974 to April 2023 was retrieved,and finally 86 eligible articles were reviewed. RESULTS AND CONCLUSION:m6A modification is a highly dynamic and reversible modification.Pathological cardiac remodeling mainly involves pathological cardiac hypertrophy,cardiomyocyte apoptosis,cardiomyocyte pyroptosis,cardiomyocyte ferroptosis,myocardial fibrosis and vascular remodeling.m6A-related enzymes can regulate pathological cardiac remodeling processes through various non-coding RNAs and different signaling pathways,which can be used as a new potential intervention for cardiovascular diseases.In pathological cardiac remodeling,research on the regulatory relationship between m6A modification and non-coding RNAs is still in its infancy.With the development of epigenetics,m6A modification in non-coding RNAs is expected to have a new development in the regulation of pathological cardiac remodeling.
ABSTRACT
OBJECTIVE@#To analyze the distribution characteristics of emerging and reemerging Oncomelania hupensis snails after the criteria for transmission control of schistosomiasis were achieved in China, so as to provide insights into assessment of schistosomiasis transmission risk and formulation of snail control strategies during the elimination phase.@*METHODS@#O. hupensis survey data in China from 2015 to 2021 were collected from the National Schistosomiasis Pevention and Control Information Management System, and the distribution characteristics of emerging and reemerging O. hupensis snails were descriptively analyzed.@*RESULTS@#Emerging and reemerging O. hupensis snails were identified in China each year from 2015 to 2021, with relatively larger areas with emerging and reemerging O. hupensis snail habitats in 2016 and 2021, and relatively higher numbers of counties (districts) where emerging and reemerging O. hupensis snails were detected in 2016 and 2021. A total of 4 586.30 hm2 of emerging O. hupensis snail habitats were found in 10 schistosomiasis-endemic provinces of China (except Fujian and Yunnan Provinces) from 2015 to 2021, with 96.80% in Anhui, Hunan and Hubei provinces, where marshland and lake endemic foci were predominant. A total of 21 023.90 hm2 of reemerging O. hupensis snail habitats were found in 12 schistosomiasis-endemic provinces of China from 2015 to 2021, with 97.67% in six provinces of Hubei, Sichuan, Jiangxi, Jiangsu, Yunnan and Anhui, where marshland and lake and hilly endemic regions were predominant. Emerging snail habitats were found in 15.08% of all schistosomiasisendemic counties (districts) in China from 2015 to 2021, and 78.75% of all emerging snail habitats were identified in 11 schistosomiasis-endemic counties (districts), with the largest area of emerging snail habitats found in Lixian County, Hunan Province (645.00 hm2). Reemerging snail habitats were found in 47.67% of all schistosomiasis-endemic counties (districts) in China from 2015 to 2021, and 43.29% of all reemerging snail habitats were identified in 11 schistosomiasis-endemic counties (districts), with the largest area of reemerging snail habitats found in Weishan Li and Hui Autonomous County of Hunan Province (1 579.70 hm2).@*CONCLUSIONS@#Emerging and reemerging O. hupensis snails were identified in China each year from 2015 to 2021, with much larger areas of reemerging snail habitats than emerging snail habitats, and larger numbers of schistosomiasis-endemic provinces and counties (districts) with reemerging snails were found that those of provinces and counties (districts) with emerging snails. Specific snail control interventions are required tailored to the causes of emerging and reemerging snail habitats. Both emergence and reemergence of O. hupensis snails should be paid attention to in marshland and lake endemic areas, and Guangxi Zhuang Autonomous Region, Shanghai Municipality and Zhejiang Province where schistosomiasis had been eliminated, and reemergence of O. hupensis snails should be given a high priority in hilly areas. In addition, monitoring of O. hupensis snails should be reinforced in snail-free areas after flooding.

Based on the content of medical professionalism and the theoretical model of knowledge, belief and practice, this paper used the methods of "inductive category construction" and "deductive category construction" to form the categories and analyze the text, taking the narrative materials of 112 "volunteer stars" outstanding individuals selected by the pre-medical student office of student affairs department of Peking University Health Science Center from 2019 to 2021 as the research subjects. The findings demonstrated that volunteer service had a positive effect on the cultivation of medical professionalism of medical freshmen, and played an effective role in guiding medical freshmen from the two dimensions of knowledge and belief, in which the role of medical voluntary service was more obvious. However, the breadth and depth of volunteer service in cultivating medical professionalism were limited. Based on this, this paper proposed that medical colleges and universities should emphasize voluntary service in the cultivation of medical professionalism, especially the development of medical voluntary service activities designed for medical students, and strengthen the cultivation effect by coordinating with other cultivation methods.
ABSTRACT
Objective:To study the effect of continuous subcutaneous insulin infusion(CSII)on the emotional disorder of children and adolescents with type 1 diabetes mellitus(T1DM)and their parents.Methods:A total of 72 children and adolescents with T1DM were divided into CSII group( n=40)and multiple daily injection(MDI)group( n=32).There were 58 healthy children and adolescents with their parents selected as control group.The emotional condition of children and adolescents in T1DM group and control group was evaluated by Depression Self-rating Scale for Children(DSRS)and the Screen for Child Anxiety Related Emotional Disorders(SCARED)respectively, and Symptom Checklist-90(SCL-90)was used for evaluating the mental health of all parents. Results:The average glycated hemoglobin A1c(HbA1c)of T1DM group was at the optimal level(7.406±1.294)%.The average HbA1c of CSII group was significantly lower than that of MDI group[(7.040±1.082)% vs(7.863±1.404)%, t=2.728, P=0.008].The depression rate of children and adolescents in T1DM group increased significantly than that of control group(31.9% vs 15.5%, χ2 =4.671, P=0.031).There were statistically significant differences among CSII group, MDI group and control group(20.0% vs 46.9% vs 15.5%, χ2 =11.591, P=0.003).The depression rate of children and adolescents in MDI group increased significantly than that of CSII group and control group(all P<0.05).CSII group showed similar results as compared with control group( P>0.05).Concerning the anxiety in children and adolescents, there was no significant difference between T1DM group and control group(19.4% vs 13.8%, χ2=0.730, P=0.393), and there were no significant differences among CSII group, MDI group and control group(15.0% vs 25.0% vs 13.8%, χ2=1.994, P=0.369).The emotional disorder prevalence of parents in T1DM group was remarkably higher than that of the control group(31.9% vs 5.2%, χ2=52.927, P<0.01).The factor scores of obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, hostility, paranoia and psychotic symptoms in T1DM group were higher than that of control group( P<0.05).There were statistically significant differences among CSII group, MDI group and control group(17.5% vs 50.0% vs 5.2%, χ2=26.126, P<0.01).The emotional disorder prevalence of parents in MDI group increased significantly than that of CSII group and control group(all P<0.05).But CSII group was same as that of control group( P>0.05). Conclusion:The children and adolescents with T1DM and their parents were high-risk population of emotional disorder.CSII can reduce not only the depression in the children and adolescents with T1DM, but also emotional disorder of their parents, thus CSII can improve the mental health in families suffering from T1DM.
ABSTRACT
Purpose@#Patients with multiple myeloma (MM) are prone to developing persistent renal insufficiency. Novel therapeutic medications have improved long-term survival, making kidney transplantation (KT) a viable treatment option for MM survivors with end-stage renal disease. This study aimed to investigate the clinical outcomes in patients with MM who have received KT. @*Methods@#Data from hospitalized patients ≥ 40 years of age with MM in the Nationwide Inpatient Sample 2016–2018 of the United States were queried. Patients were classified as having or not having undergone KT, as well as the stage of chronic kidney disease (CKD) for those who had not received KT. Propensity-score matching (PSM) was applied to balance the characteristics between the groups. Binary logistic regression was utilized to determine the associations between study variables and inhospital mortality, unfavorable discharges, prolonged length of stay (LOS), and major complications. @*Results@#In total, 50,654 hospitalized patients with MM were identified, of whom 165 (0.3%) had received KT and 50,489 had not (5,905 at stage 5 CKD [CKD5D], 11,559 at stage 1–4 CKD [CKD1-4D], and 33,025 who were CKD-free). After PSM, between-group demographic and hospital-related characteristics were balanced. Binary regression analysis revealed that, compared to patients who were CKD-free, patients at CKD5D were significantly more likely to experience a prolonged LOS (odds ratio [OR], 1.31; 95% confidence interval [CI], 1.01–1.70) after adjusting for relevant confounders. Furthermore, compared to CKD-free patients, those who underwent KT were significantly more likely to have sepsis (OR, 1.48; 95% CI, 1.02–2.14). However, KT showed no association with the other adverse inpatient outcomes. @*Conclusions@#Although KT is not common in MM patients, those who had undergone KT had comparable hospital outcomes to CKD-free patients. These data will help clinicians deliver better consultations to MM patients attempting to receive KT.
ABSTRACT
Objective:To explore the effectiveness of positive cognitive therapy in improving anxiety and depression, psychological distress, positive awareness, and quality of life in cancer patients, with a view to providing an experience for practical clinical application.Methods:This study was a quasi experimental study, in which 96 patients with cancer radiotherapy attending Shanghai Proton Heavy Ion Center from April 2019 to January 2021 were selected as study subjects by convenience sampling, and were divided into 47 cases in the intervention group and 49 cases in the control group according to the district group randomization method. The control group was given conventional psychological care and health education, and instructed to learn the audio and video of positive cognitive therapy at the end of the study; the intervention group was given 8 sessions of positive cognitive therapy over a period of 4 weeks. At the end of the intervention, the Pdistress Thermometer, the Generalized Anxiety Inventory, the Patient Health Questionnaire Depression Inventory, the Brief Version of the Five Factor Positive Thinking Inventory, and the European Organization for Research and Treatment of Cancer, Quality of Life Questionnaire C30 were used to compare the psychological distress, anxiety and depression, positive cognitive awareness and quality of life of the two groups.Results:After the implementation of the positive cognitive therapy intervention, the incidence rate of anxiety and depression in the intervention group was 12.8% (6/47) and 14.9% (7/47), respectively, both of which were significantly lower than the 30.6% (15/49) and 32.7% (16/49) in the control group, with statistically significant differences ( χ2=3.80, 3.89, both P<0.05); after intervention the scores on the observation, description and perceived action dimensions of the Brief Version of the Five Factor Positive Thinking Scale were (23.8 ± 6.5), (28.6 ± 5.4) and (31.3 ± 5.3) respectively, all significantly higher than those of the control group (20.0 ± 5.1), (23.7 ± 5.5) and (26.9±6.2), the differences were statistically significant ( t=2.79, 3.59, 3.21, all P<0.05); the post-intervention score on the Emotional Functioning dimension of the European Organization for Research and Treatment of Cancer Quality of Life Scale (94.3 ± 7.4) was significantly higher than that of the control group (88.8 ± 11.4), with a statistically significant difference ( t=-2.28, P<0.05). Conclusions:Positive cognitive therapy is effective in relieving anxiety and depression, increasing positive awareness, and improving emotional distress in cancer patients. It can be incorporated into the daily psychological care process of tumor patients, giving them appropriate guidance and support to help improve their psychological and quality of life.
ABSTRACT
Objective:To study the clinical characteristics of ureaplasma urealyticum (UU) infection in preterm infants with gestational age <34 weeks.Methods:From January 2017 to December 2021, premature infants with gestational age <34 weeks admitted to neonatal department of our hospital were enrolled in this prospective cohort study. UU-DNA from respiratory tract samples were examined using quantitative fluorescence polymerase chain reaction method. The infants were assigned into UU (+) group and UU (-) group. Perinatal factors and clinical characteristics were compared between the two groups.Results:A total of 182 preterm infants were enrolled, including 59 cases (32.4%) in UU (+) group and 123 (67.6%) in UU (-) group. UU (+) group had significantly lower gestational age and birth weight and significantly higher incidences of vaginal delivery, premature rupture of membranes (PROM) >18 h and maternal chorioamnionitis than UU (-) group ( P<0.05). Compared with UU (-) group, UU (+) group had significantly higher leucocyte count, neutrophil count and interleukin-6 at 1, 24 and 72 h after birth ( P<0.05). No significant differences existed in C-reactive protein and procalcitonin between the two groups at each time point ( P>0.05). In UU (+) group, the incidences of intrauterine pulmonary infection and bronchopulmonary dysplasia (BPD) were higher and the incidence of respiratory distress syndrome was lower than UU (-) group ( P<0.05). No significant differences existed in the incidences of intraventricular hemorrhage, periventricular leukomalacia, feeding intolerance, necrotizing enterocolitis, retinopathy of prematurity between the two groups ( P>0.0 5). UU (+) group had significantly longer duration of oxygen therapy than UU (-) group ( P<0.05). No significant differences existed in the duration of invasive mechanical ventilation and hospital stay between the two groups ( P>0.05). Conclusions:Preterm infants <34 weeks with positive UU in respiratory tract secretions have higher incidences of vaginal delivery, PROM>18 h and maternal chorioamnionitis. Leukocyte and neutrophil count and interleukin -6 are higher in these infants. They need prolonged oxygen therapy and have increased risks of intrauterine pulmonary infection and BPD.
ABSTRACT
As prominent immune cells in the central nervous system, microglia constantly monitor the environment and provide neuronal protection, which are important functions for maintaining brain homeostasis. In the diseased brain, microglia are crucial mediators of neuroinflammation that regulates a broad spectrum of cellular responses. In this review, we summarize current knowledge on the multifunctional contributions of microglia to homeostasis and their involvement in neurodegeneration. We further provide a comprehensive overview of therapeutic interventions targeting microglia in neurodegenerative diseases. Notably, we propose microglial depletion and subsequent repopulation as promising replacement therapy. Although microglial replacement therapy is still in its infancy, it will likely be a trend in the development of treatments for neurodegenerative diseases due to its versatility and selectivity.

This report presented the endemic status of schistosomiasis and analyzed the data collected from the national schistosomiasis prevention and control system and national schistosomiasis surveillance program in the People’s Republic of China in 2022. Among the 12 provinces (municipality and autonomous region) endemic for schistosomiasis, Shanghai Municipality, Zhejiang Province, Fujian Province, Guangdong Province and Guangxi Zhuang Autonomous Region continued to maintain the achievements of schistosomiasis elimination, and Sichuan and Jiangsu provinces maintained the criteria of transmission interruption, while Yunnan, Hubei, Anhui, Jiangxi and Hunan provinces maintained the criteria of transmission control by the end of 2022. A total of 452 counties (cites, districts) were found to be endemic for schistosomiasis in China in 2022, with 27 434 endemic villages covering 73 424 400 people at risk of infections. Among the 452 endemic counties (cities, districts), 75.89% (343/452), 23.45% (106/452) and 0.66% (3/452) achieved the criteria of elimination, transmission interruption and transmission control of schistosomiasis, respectively. In 2022, 4 317 356 individuals received serological tests for schistosomiasis, and 62 228 were sero-positive. A total of 208 646 individuals received stool examinations for schistosomiasis, with one positive and another two cases positive for urine microscopy, and these three 3 cases were imported schistosomiasis patients from Africa. There were 28 565 cases with advanced schistosomiasis documented in China by the end of 2022. Oncomelania hupensis snail survey was performed in 18 891 endemic villages in China in 2022 and O. hupensis snails were found in 6 917 villages (36.62% of all surveyed villages), with 8 villages identified with emerging snail habitats. Snail survey was performed at an area of 655 703.01 hm2 and 183 888.60 hm2 snail habitats were found, including 110.58 hm2 emerging snail habitats and 844.35 hm2 re-emerging snail habitats. There were 477 200 bovines raised in the schistosomiasis endemic areas of China in 2022, and 113 946 bovines received serological examinations for schistosomiasis, with 204 sero-positives detected. Among the 131 715 bovines received stool examinations, no positives were identified. In 2022, there were 19 726 schistosomiasis patients receiving praziquantel chemotherapy, and expanded chemotherapy was performed in 714 465 person-time for humans and 234 737 herd-time for bovines in China. In 2022, snail control with chemical treatment was performed at an area of 119 134.07 hm2, and the actual area of chemical treatment was 65 825.27 hm2, while environmental improvements were performed at an area of 1 163.96 hm2. Data from the national schistosomiasis surveillance program of China showed that the mean prevalence of Schistosoma japonicum infections was both zero in humans and bovines in 2022, and no S. japonicum infection was detected in O. hupensis snails. These data demonstrated that the endemic status of schistosomiasis continued to decline in China in 2022, with 3 confirmed schistosomiasis patients that had a foreign nationality and all imported from Africa, and the areas of snail habitats remained high. Further improvements in the construction of the schistosomaisis surveillance and forecast system, and reinforcement of O. hupensis survey and control are required to prevent the re-emerging schistosomiasis.
ABSTRACT
Taking the graduation ceremony of Peking University Health Science Center in 2020 as the observation object, this paper used Collins’ Interactive Ritual Chains Theory to analyze the form, theme and featured part of this ceremony from the dimensions of physical co-presence, barrier to outsiders, joint focus of attention and shared mood. It was found that the ceremony in medical colleges had an impact on the cognition, behavior and spirit of junior medical students in terms of group identity, emotional energy, group symbols and moral sense, which played a good role in professionalism education. Some enlightenment and thinking were obtained on this basis to provide some references for medical colleges to give full play to the educational function of the professionalism in the post-epidemic era.
ABSTRACT
ObjectiveTo determine the effect of blended teaching method in epidemiology teaching for students in clinical medicine. MethodsA total of 143 students in clinical medicine at Tongji University School of Medicine in the fall semester of 2021‒2022 were enrolled in the study. A self-assessment questionnaire was used to assess the satisfaction and recognition on the blended teaching method in epidemiology. ResultsIn terms of teaching effect， 84.6% of the students obtained excellent and good grades in the final evaluation， while 7.0% of the students did not pass the final exam. Approximately 21.0% of the students had difficulties in understanding the concept of bias and its control. The 90.2% were satisfied with the design of the blended teaching method， 84.2% were satisfied with the online video courses， and 60.9% completed more than 75.0% of the online learning resources before class. Additionally， 80.5% of the students responded that they could master the knowledge of epidemiology， and 81.2% considered that the blended teaching method may facilitate personalized learning and they could learn more knowledge of epidemiology. ConclusionBlended teaching method attains remarkable achievements in epidemiology teaching. However， curriculum design， teaching effect， and acceptance may be further strengthened.
ABSTRACT
Objective:To study the clinical features of infective endocarditis (IE) with positive anti-neutrophil cytoplasmic antibodies (ANCA) in order to improve the level of diagnosis and treatment.Methods:Eighteen IE cases with positive ANCA admitted to the First Affiliated Hospital of Zhengzhou University from June 2016 to July 2021 were collected. The demographic information, clinical symptom, laboratory tests, imaging examinations, treatment and clinical outcomes were analyzed retrospectively. Statistical program for social sciences (SPSS) 20.0 statistical software was used for analysis. Enumeration data were expressed as the number of cases and percentage (%), and measurement data were expressed as Mean± SD. Results:Twelve cases were male and 6 cases were female, with an average age of (50±16) years. Sixteen patients had positive PR3-ANCA, in which 2 cases had positive myeloperoxidase (MPO)-ANCA. The major clinical manifestations included fever (88.9%, 16/18), anemia (72.2%, 13/18), splenomegaly (44.4%, 8/18), cardiac murmur (33.3%, 6/18), arthralgia (22.2%, 4/18), liver damage (22.2%, 4/18), thromboembolic events (16.7%, 3/18), Osler's node (11.1%, 2/18) and renal dysfunction (11.1%, 2/18). Higher C-reactive protein (CRP), erythrocyte sedimentation (ESR) and procalcitionin (PCT) were detected in 83.3% (15/18) patients. The positive rate of blood culture was 50.0%(9/18) and streptococcus was the most common pathogen (77.8%, 7/9). Echocardiograms of all patients showed abnormal vegetation, most commonly involving the mitral valve (66.7%, 12/18) and aortic valve (33.3%, 6/18). Two patients were misdiagnosed as ANCA associated vasculitis (AAV), but the other one was diagnosed as AAV with IE as the first manifestation. Except for one case who died of multiple organ failure, all cases reached clinical recovery after surgery and antibiotic therapy.Conclusion:IE patients with positive ANCA may present with the clinical manifestations similar to AAV. We should highly alert to avoid misdiagnosis and treatment.
ABSTRACT
To analyze the clinical characteristics of patients with antisynthetase syndrome (ASS) and positive anti-Ro52 antibody. The clinical data of 203 ASS patients admitted to the First Affiliated Hospital of Zhengzhou University from 2017 to 2020 were analyzed retrospectively. Demographics, clinical manifestations, laboratory results, treatment and outcome were collected including data of 18 patients with rapidly progressive interstitial lung disease (RP-ILD). In total, the majority were women (148,72.9%). The average onset age was (51.9±13.3) years. There were 163 (80.3%) patients with positive anti-Ro52 antibody. The positivity in women (77.3% vs. 55.0%, P=0.004) was higher, and the median time from disease onset to diagnosis [4.5 (2.0, 24.0) months vs. 2.0 (1.0, 12.0) months, P=0.024] was longer in patients with positive anti-Ro52 antibody than those negative. Compared with negative patients, patients with positive anti-Ro52 antibody had a higher incidence of interstitial lung disease (ILD) (96.9% vs. 65.0%, P<0.001), arthritis (33.7% vs. 17.5%, P=0.046), and arthralgia (39.3% vs. 20.0%, P=0.022). Higher rate of positve antinuclear antibody (ANA) (85.3% vs. 55.0%, P<0.001), lower rate of positive anti-Jo-1 antibody (32.5% vs. 50.0%, P=0.039), lower albumin level [(34.6±5.2) g/L vs. (37.3±4.7) g/L, P=0.004] and lower lymphocyte counts [(1.4±0.8) ×10 9/L vs. (1.8±0.8) ×10 9/L, P=0.014] were more common in patients with positive anti-Ro52 antibody. The presence of anti-Ro52 antibody is associated with a particular phenotype of ASS, leading to common ILD, involvement of joints, high ANA positivity, low albumin and low lymphocyte counts.
ABSTRACT
To study the clinical features of myeloperoxidase(MPO) antineutrophil cytoplasmic antibody (ANCA) associated hypertrophic pachymeningitis (HP). Clinical data of 15 cases diagnosed with MPO-ANCA vasculitis complicated with HP were retrospectively analyzed. Nine cases were males and the other 6 were females, with an average age of (58±8) years. All cases presented with chronic headache. Contrast-enhanced magnetic resonance imaging (MRI) scan showed local or diffused thickening of cerebral and/or spinal dura matter while brain parenchyma were normal. Nine cases developed multiple cranial nerve paralysis, with trigeminal nerve and auditory nerve involved most commonly. The main clinical manifestations were facial pain, hearing loss and tinnitus. Two cases were complicated with hypertrophic spinal pachymeningitis (HSP) and 4 cases were complicated with pulmonary diseases. Positive serum perinuclear pattern ANCA (pANCA) and MPO could be found in all cases, positive serum IgG 4 was seen in two patients. erythrocyte sedimentation rate(ESR;25-116 mm/1h) and C-reactive protein (CRP;29.02-146.00 mg/L) were both elevated in 14 cases. Nine cases had elevated intracranial pressure[180-235 mmH 2O (1 mmH 2O=0.009 8 kPa)] and abnormal protein level (457.6-3710.0 mg/L) in cerebrospinal fluid. Six cases were treated with glucocorticoids (prednisone 20-60 mg/d) and 9 cased with glucocorticoids and immunosuppressants (methotrexate 15 mg/week or cyclophosphamide 100 mg/d po). All patients achieved remission. MPO-ANCA associated HP is a special type of central nervous system involvement in ANCA associated vasculitis (AAV). It rarely involves the lung or kidney. Steroids and immunosuppressive agents are effective. In HP with unknown underlying diseases, it is suggested to screen ANCA and IgG 4 tests for AAV or IgG 4-related disease.
ABSTRACT
OBJECTIVE To systematically review the efficacy and safety of kidney -tonifying Chinese patent medicine combined with phosphodiesterase type 5（PDE5）inhibitors in the treatment of erectile dysfunction （ED），and to provide evidence - based reference for clinical medication . METHODS Retrieved from PubMed ，Embase，Cochrane Library ，Web of Science ，VIP， China Biomedical Literature Database ，CNKI and Wanfang database ，randomized controlled trials （RCTs）of kidney -tonifying Chinese patent medicine combined with PDE 5 inhibitors（trial group ）versus PDE 5 inhibitors or kidney -tonifying Chinese patent medicine alone （control group ）were collected . The search period was from the establishment of the database to February 15，2022. After literature screening and data extraction ，the risk of bias assessment tool recommended in Cochrane System Reviewer ’s Handbook 6.1.0 was used to evaluate the quality of the included literature ；Stata 16.0 software was used for network meta -analysis； and the funnel plot was used for publication bias analysis . RESULTS A total of 23 RCTs were included ，with a total of 2 417 patients， involving 8 kinds of Chinese patent medicines ， including Congrong yishen granule ，Canrong zhutian capsule ， Compound xuanju capsule ， Huanshao capsule ， Shanhaidan granule， Shengjing capsule ， Shisanwei ziyin zhuangyang capsule，Shugan yiyang capsule . The results of network meta analysis showed that in terms of total effective rate ，Compound xuanju capsule combined with PDE 5 inhibitor，Shengjing capsule combined with PDE 5 inhibitor，Shugan yiyang capsule combined with PDE 5 inhibitor had higher total effective rate ；in terms of international index of erectile function 5，the scores of Compound xuanju capsule combined with PDE 5 inhibitor，Congrong yishen granule combined with PDE 5 inhibitor，and Canrong zhutian capsule combined with PDE 5 inhibitor were higher ；in terms of safety ，the incidence of adverse drug reactions caused by Huanshao capsule ，Shanhaidan granule and Shugan yiyang capsule were lower . CONCLUSIONS Kidney-tonifying Chinese patent medicine combined with PDE 5 inhibitor can improve the erectile function of ED patients and reduce the occurrence of adverse drug reactions . In terms of efficacy and safety ，Compound xuanju capsule combined with PDE 5 inhibitor is the best .
