Trend analysis of chronic kidney disease incidence and mortality in Chinese population based on age-period-cohort model / 公共卫生与预防医学

Objective To investigate the changing trend and epidemiological characteristics of the incidence and mortality of chronic kidney disease (CKD) with age, period and birth cohort in Chinese population. Methods Based on the data of incidence and mortality of CKD in Chinese population aged 20-80 years from 1990 to 2019 in GHDx database, joinpoint regression model was used to analyze the incidence and mortality trend of CKD. An age-period-cohort model was constructed to analyze the effects of age, period, and birth cohort on the trend of CKD incidence and mortality. Results Joinpoint regression analysis showed that the standardized incidence rate of chronic kidney disease in Chinese population increased from 146.37/100 000 in 1990 to 161.52/100 000 in 2019, while the standardized mortality rate decreased from 12.98/100 000 in 1990 to 11.23/100 000 in 2019. The APC model analysis showed that the risk of CKD incidence and death in the Chinese population increased with age, while the risk of CKD incidence increased with the increase of period. The risk of death did not change significantly with the increase of period. The cohort born later had a lower risk of CKD incidence and death compared to the cohort born earlier. Conclusion At present, the age effect and period effect of the incidence and death risk of chronic kidney disease in China are dominant. It is important to take effective measures and intervene in a timely manner, especially to strengthen the protection of older high-risk groups born earlier.

Formulation and technology of oxymatrine-astragaloside IV coloaded liposomes based on quality by design / 药学学报

To optimize the formulation and technology of oxymatrine-astragaloside IV coloaded liposomes (Om-As-Lip) based on quality by design (QbD) principles, and further to verify the feasibility of its amplification process, Om-As-Lip was prepared by ethanol injection combined with pH gradient method. The critical material attributions of Om-As-Lip were evaluated by dual-risk analysis tools and Plackett-Burman design (PBD). The formulation of Om-As-Lip was further optimized with the Box-Behnken design (BBD). The design space was also established based on the contour plots of BBD. In order to further investigate the amplification process of Om-As-Lip, the critical process parameters of high-pressure homogenization (HPH) were optimized by single-factor test, and the quality of the final product was also evaluated. The results of risk analysis and PBD confirmed that the astragaloside concentration, cholesterol concentration, and phospholipid ratio (HSPC∶SPC) were the ctitical material attributes. The model established by BBD had a good predictability, and the optimized mass ratio of As to phospholipids was 1∶40, cholesterol to phospholipids was 1∶10, HSPC to SPC was 51∶9. The design space of Om-As-Lip was as follows: the ratio of cholesterol to phospholipids was 1∶12-1∶5 and HSPC to SPC was 1∶7-17∶3. The optimized high-pressure homogenization pressure was 600 bar, temperature was 4 ℃, and cycle times was 6 times for HPH-Om-As-Lip. The quality of Om-As-Lip prepared based on the QbD concept can meet the expected CQAs, and the formulation and technology established can provide a reliable experimental basis for its future development and applications.

Pathogenesis of Diabetes from Theory of Spleen Deficiency Causing Diabetes Based on Intestinal Innate Immunity / 中国实验方剂学杂志

In western medicine， the small intestine anatomically belongs to the digestive system and is also an important immune organ of the body. The innate immune system of the small intestine consists of a tissue barrier， innate immune cells， and innate immune molecules. The dysfunction of any part can cause metabolic disorders and eventually lead to diabetes. In the pathogenesis of diabetes， traditional Chinese medicine （TCM） has the theory of ''spleen deficiency causing diabetes''， which points out that the impaired spleen function results in inadequate transformation， impaired essence spread， and turbidity by essence accumulation， which is the core pathological link of blood glucose metabolism disorder in diabetes. In terms of the relationship between the small intestine and the spleen， the theory of TCM holds that the small intestine is located in the abdomen and the abdomen is dominated by the spleen. The digestion， absorption， and endocrine functions of the small intestine are also similar to the functions of spleen in governing movement and transformation and spreading essence by virtue of spleen Qi. Therefore， the anatomical and physiological functions of the small intestine in western medicine are closely related to the spleen in TCM. At the same time， the spleen is closely related to the innate immune function of the small intestine in TCM. The spleen participates in the generation and distribution of defense Qi， and the process of defense Qi playing the external function is similar to the process of the activation of the innate immune response. The spleen is also an important organ involved in fluid metabolism， which can cooperate with the lung and kidney to timely remove turbid fluid from the body. It can also work with the stomach as the hub of Qi ascending and descending and regulate the physiological activities of "clear Yang" and "turbid Yin"， so as to ensure the homeostasis of the internal environment of the body， which is the basis for maintaining the normal function of the innate immunity of the small intestine. Therefore， taking "spleen deficiency causing diabetes" as a bridge， the theory of TCM and western medicine were combined to explain the relationship between small intestinal innate immunity imbalance and the pathogenesis of diabetes from the perspective of TCM， which is helpful to understand the pathogenesis of diabetes in a deeper level and also provide a new perspective and new way for the prevention and treatment of this disease with TCM.

Application of Sphenoid Sinus Morphological Characteristics in Sex Estimation Based on Magnetic Resonance Imaging Images / Aplicación de las Características Morfológicas del Seno Esfenoidal en la Estimación del Sexo Basada en Imágenes de Resonancia Magnética

SUMMARY: Sex determination of unknown persons plays an important role in forensic science. As most bones used for sex determination are recovered in incomplete state, it is often necessary to use bones that are recovered intact e.g., the sphenoid sinus. This study aimed to evaluate the diagnostic value of sphenoid sinuses dimensions for sex determination using Magnetic Resonance Imaging (MRI) images in Chinese adults. MRI images of 79 sphenoid sinuses (from 44 men and 35 women) were retrospectively selected. The height, anterior-posterior diameter, area, and perimeter were measured in the midsagittal view of the sphenoid sinuses. All data were subjected to descriptive and discriminative functional analysis with unpaired t-test and canonical discriminant. Comparison between male and female groups showed significant statistical differences regarding the height, anterior-posterior diameter, area, and perimeter of sphenoid sinuses. The predictive accuracy rate of the sphenoid sinus to identify sex was 63.6 % in males and 62.9 % in females with an overall accuracy of 63.3 %. This study proposed the importance of sexual dimorphism of sphenoid sinus dimensions, especially if other methods are not available. It suggested using MRI in forensics science thus obviating the complete dependence on the usage of conventional computed tomography (CT) and facilitating the study of forensic anatomy at the level of soft tissue.

La determinación del sexo de personas desconocidas juega un papel importante en la ciencia forense. Como la mayoría de los huesos utilizados para la determinación del sexo se recuperan en un estado incompleto, a menudo es necesario utilizar huesos recuperados intactos, por ejemplo, el seno esfenoidal. Este estudio tuvo como objetivo evaluar el valor diagnóstico de las dimensiones de los senos esfenoidales para la determinación del sexo utilizando imágenes de resonancia magnética en individuos adultos chinos. Se seleccionaron retrospectivamente imágenes de resonancia magnética de 79 senos esfenoidales (de 44 hombres y 35 mujeres). La altura, el diámetro anteroposterior, el área y el perímetro de los senos esfenoidales, se midieron en vista mediana sagital. Todos los datos se sometieron a análisis funcional descriptivo y discriminativo con prueba t no pareada y discriminante canónico. La comparación entre los grupos de hombres y mujeres mostró diferencias estadísticas significativas en cuanto a la altura, el diámetro anteroposterior, el área y el perímetro de los senos esfenoidales. La tasa de precisión predictiva del seno esfenoidal para identificar el sexo fue del 63,6 % en hombres y del 62,9 % en mujeres, con una precisión general del 63,3 %. Este estudio propuso la importancia del dimorfismo sexual de las dimensiones del seno esfenoidal, especialmente si no se dispone de otros métodos. Se sugiere utilizar la resonancia magnética en la ciencia forense, obviando así la dependencia total del uso de la tomografía computarizada convencional y facilitando con esto el estudio de la anatomía forense a nivel de los tejidos blandos.

Characteristics, cellular and molecular mechanisms of renal aging and nutritional intervention strategies / 中华老年医学杂志

Renal aging is a gradual process of degenerative changes in tissue structure and physiological function and is closely related to the occurrence and development of acute kidney injury(AKI)and chronic kidney disease(CKD). The cellular and molecular mechanisms of renal aging mainly include cellular senescence and reduced autophagy, and are regulated by nutritional factors.Promoting reasonable and moderate energy-and protein-restricted diets, strengthening the supervision of food additives and preservatives, cultivating safety awareness of residents, and strictly controlling the daily salt intake are potential nutritional intervention strategies to prevent and delay renal aging.Given the limited number of studies, there is an urgent need to further explore the effectiveness of the above strategies to provide a new evidence-based approach to formulating precise and feasible personalized nutritional intervention programs.

The National Medical Center for Major Public Health Events invited experts in fields of infectious diseases, respiratory medicine, intensive care, pediatrics and fever clinic to develop this quick guideline based on the current best evidence and extensive clinical practices. This quick guideline aims to standardize the diagnosis and treatment of novel coronavirus Omicron infection, and to improve the disease management abilities of clinicians.

Expression and Detection Value of 6 Chlamydia Trachomatis Protein Antibodies in Tubal Factor Infertility / 中山大学学报(医学科学版)

ObjectiveTo further study the pathogenic role of different types of Chlamydia trachomatis （CT） proteins in tubal factor infertility， evaluate the clinical detection value of Chlamydia trachomatis protein antibody in predicting tubal factor infertility. MethodsA total of 58 cases of tubal factor infertility （TFI）， 41 cases of fertile controls （FC） and 18 cases of infertile controls （IFC） were included. For serum detection， first， CT-IgG ELISA kit was used to detect the expression of CT-IgG in serum of three groups of people； then， 6 kinds of Chlamydia trachomatis proteins were expressed and purified in the early stage to establish the antibody test for these proteins， and ELISA detection method was used to detect the expression of their antibodies in the serum of TFI group， FC group and IFC group， respectively； and finally， the antibody OD value of the 6 kinds of Chlamydia trachomatis proteins in the three groups of subjects were statistically described， and CT-IgG was used as the reference standard to draw the receiver operating characteristic curve （ROC curve） of each CT antibody. The Youden Index determines the cutoff value for each antibody. Taking TFI as the reference class， two disordered multiple classification logistic regression models were established with the FC and IFC groups， respectively； and the reference class was used to explore the value of various antibodies and age in predicting TFI， FC and IFC of Chlamydia trachomatis. The back-off method was used to screen the variables. ResultsThe OD value of CT376 antibody in the TFI group was higher than that in the FC group （0.86 vs. 0.60， P=0.026）. The CT376 antibody OD value in the TFI group was higher than that in the IFC group （0.86 vs. 0.64， P=0.026）. The CT443 antibody OD value in the IFC group was higher than that in the TFI group （0.59 vs. 0.34， P=0.036） and higher than that in the FC group （0.59 vs. 0.30， P=0.02）. The multiple classification logistic regression analysis established between TFI and FC showed that CT-IgG ［P<0.001， OR=0.084， 95%CI （0.025， 0.284）］， CT376 antibody ［P=0.068， OR=0.359， 95%CI （0.120， 1.078）］. CT-IgG is an independent risk factor for tubal infertility， and CT376 antibody cannot be an independent risk factor for tubal infertility. The multiple classification logistic regression analysis established between TFI and IFC showed that among infertile patients， CT-IgG ［P<0.05， OR=0.194， 95%CI （0.046， 0.817）］， CT376 antibody ［P<0.05， OR=0.176， 95%CI （0.038， 0.818）］ and CT381 antibody ［P<0.05， OR=0.112， 95%CI （ 0.016， 0.796）］ were independent risk factors for tubal infertility. ConclusionThe expression of CT376 antibody in tubal infertility patients is higher than that in fertile and infertile controls， suggesting that CT-induced tubal factor infertility may be related to CT376. CT-IgG， and CT376 antibodies are meaningful in predicting CT-induced tubal factor infertility.

Improvement of high-quality evaluation criteria of Chinese patent medicines based on whole process control / 中国中药杂志

Chinese patent medicines(CPMs) are unique therapeutic drugs in China. Establishing and improving the evaluation criteria is an important measure to promote the high-quality development of CPMs. Based on the "evaluation criteria of high-grade CPMs with quality as the core index" established by our group in 2018, the "high-quality evaluation criteria for CPMs based on whole process control" was proposed in the present study in 2022. The scope of application and basic principles of the new criteria were clarified. A quality evaluation scoring table was established in the new criteria, including five parts: raw material selection, production process, quality control, efficacy evaluation, and brand building. The technical evaluation indexes involved have increased from 20% in the original criteria to 70% in the new criteria, and efficacy evaluation has been added in the new criteria. The subjective evaluation indicators account for a large proportion in the original criteria, which is prone to bias. The improved criteria overcome this shortcoming. It is expected that the new criteria as a basis can play a better role in the selection of high-quality products of CPMs, guide enterprises and institutions to participate actively in the evaluation and research of high-quality CPMs, and promote the high-quality development of CPMs.

Localized Practice and Ethical Dilemma of Social Work in Hospice Care: Taking the Casework of Terminal Cancer Patient as an Example / 中国医学伦理学

The positive role of hospice social work in responding to the needs of terminal cancer patients and their families has been highlighted, and has also triggered discussions on localized ethical issues. Taking the casework of terminal cancer patients as an example, this paper analyzed the specific manifestations and causes of ethical dilemmas in the practice of hospice social work, and then provided ideas for coping with them. It was found that hospice care casework workers face four ethical dilemmas, including quality of life dilemmas, emotional boundaries dilemmas, power relationship dilemmas, and cultural respect dilemmas. Service managers can enhance the ethical issue response ability of front-line workers by improving the collaborative service mechanism between medical and social institutions, constructing a whole-process professional supervision system, conducting skills training for caring social workers, and expanding patient and family life education services. The ethical dilemmas in hospice social work service are localized, and will affect the service effect. The response to these issues requires the joint participation of the government, society, universities, hospitals, and front-line social workers.

Institutions can further improve their ethics review work level after passing the CAP accreditation. However, the operational efficiency of each department in the ethics review system needs to be further improved when performing relevant functions in accordance with the certification requirements. Based on the experience and summary in the work of the ethical review system, this paper analyzed the main factors that affect the efficiency of the ethical review system and put forward improvement strategies from six aspects: organizational leadership, incentive policies, quality supervision, system construction, talent training, and promotion through evaluation, with a view to providing reference for improving the efficiency of ethical review, and promoting multi-department coordination and system integration.

Exploration of the relationship between the storage time of leukodepleted red blood cell and transfusion adverse reactions / 中国输血杂志

【Objective】 To explore the relationship between the storage time of leukodepleted red blood cells and transfusion adverse reactions by analyzing the occurrence of transfusion adverse reactions of patients after leukodepleted red blood cells transfusion from four hospitals. 【Methods】 By using the electronic medical record management system, the collection and transfusion dates of leukodepleted red blood cells from four hospitals in Enshi Prefecture from 2018 to 2022, as well as the information on transfusion adverse reactions, were retrieved. 【Results】 From 2018 to 2022, a total of 697 61 bags of leukodepleted red blood cells were transfused in four hospitals, resulting in 166 cases of transfusion adverse reactions, among which 93 were allergic reactions, 63 were non hemolytic febrile reactions, and 10 were others, with a total incidence rate of transfusion adverse reactions at 0.24%. The average storage time of leukodepleted red blood cells with and without transfusion adverse reactions was (20.25±6.31) and (19.88±5.50) days, respectively. With a storage time of 7 days as the threshold, the incidence of transfusion adverse reactions was the lowest for a storage time of 15~21 days. The incidence of transfusion adverse reactions of leukodepleted red blood cells in two groups (with storage days ≤21 days and >21 days) was not statistically significant(P>0.05). 【Conclusion】 Allergic reactions were the main type of transfusion adverse reaction caused by leukodepleted red blood cells, and the incidence of transfusion adverse reactions decreased and then increased with the prolongation of the storage time of leukodepleted red blood cells. There was no significant difference in the incidence of transfusion adverse reactions with leukodepleted red blood cells stored for ≤ 21 days and >21 days.

HPLC fingerprint，content determination and transferring patterns of index components of Xintongshu spray / 中国药房

OBJECTIVE To establish the HPLC fingerprint of Xintongshu spray， determine the contents of identified components， and investigate the transferring patterns of the index components of decoction pieces， intermediates and spray， so as to provide scientific reference for technology management and quality control of Xintongshu spray. METHODS HPLC fingerprints of 13 batches of Xintongshu spray were established by the Similarity Evaluation System for Chromatographic Fingerprints of TCM （2012 edition）， and common peaks were identified； the contents of identified components were determined by HPLC. The paeonol in Moutan Cortex and ferulic acid in Chuanxiong Rhizoma were used as index components to investigate the transferring patterns of them in decoction pieces， intermediates and spray. RESULTS There were a total of 33 common peaks in the fingerprints of 13 batches of Xintongshu spray， and the similarities were more than 0.994. Eight components were identified， i.e. gallic acid （peak 5）， oxypaeoniflorin （peak 9）， chlorogenic acid（peak 10）， caffeic acid （peak 14）， paeoniflorin （peak 17）， ferulic acid （peak 21）， senkyunolide Ⅰ （peak 27） and paeonol （peak 31）. The contents of 8 components ranged from 0.590 3- 0.719 7， 0.565 7-0.851 3， 0.279 4-0.368 1， 0.080 6-0.106 1， 1.922 5-3.033 5， 0.151 3-0.191 6， 0.250 6-0.336 0， 3.056 7-4.161 0 mg/mL， respectively. The average transfer rates of paeonol and ferulic acid from decoction pieces to sprays were 63.76% and 38.06%， respectively. It was also found that the process in which the loss of paeonol was more than 30% was the extraction by percolation and negative pressure concentration of Moutan Cortex. The process in which the loss of ferulic acid was more than 50% was the steam distillation extraction process of Chuanxiong Rhizoma. CONCLUSIONS The established HPLC fingerprint and content determination method of Xintongshu spray are reproducible and specific. The key processes that cause a decrease in the average transfer rates of the index components are the extraction by percolation and negative pressure concentration of Moutan Cortex and steam distillation extraction of Chuanxiong Rhizoma.

With the growing demand of personalized medicine for children, it is especially important to develop medicines for children. In this study, using metoprolol tartrate as model drug, we developed 3D printed chewable tablets suitable for children with automated dosage distribution using semi-solid extruded (SSE) 3D printing technology. Based on the quality by design concept, this study prepared a semi-solid material with good printability using gelatin as the substrate, constructed 3D models and printed tablets with the aid of computer-aided design. The printing parameters were optimized and determined as follows: print temperature of 35-37 ℃, print speed of 25 mm·s-1, fill rate of 15%, and number of outer profile layers of 2. Subsequently, the printing process and the quality uniformity of the tablets were verified, and a linear relationship between the dose and the number of model layers was obtained. Finally, 3D printed chewable tablets were superior in terms of appearance, dose accuracy and compliance compared with traditional split-dose commercially available tablets. In this study, 3D printed metoprolol tartrate chewable tablets with good performance were successfully prepared to address the personalized medication needs of pediatric patients.

Unfortunately, the evaluation of cardiac function in children with CHD is mainly focused on the left ventricle. With the further understanding of cardiac hemodynamics, the monitoring of RV function has gradually become an important part of cardiac intensive care department. We totally searched five databases including Pubmed, Embase, Cochrane, Wanfang Med, as well as China National Knowledge Infrastructure (CNKI) and reviewed the clinical research progress of the application of TAPSE in the evaluation of RV systolic function in children with CHD to provide a theoretical basic for the monitoring of RV function before and after operation in children with CHD.

Impact of sarcopenia on mortality in patients undergoing maintenance hemodialysis / 中华肾脏病杂志

Objective:To investigate the impact of sarcopenia on mortality in maintenance hemodialysis (MHD) patients.Methods:It was a retrospective cohort study. MHD patients admitted to the blood purification center of Guangzhou Red Cross Hospital in March 2021 were recruited. Demographic data and laboratory indicators, grip strength, and bioelectrical impedance analysis indexes were collected. The patients were divided into sarcopenia group and non-sarcopenia group based on whether they had sarcopenia or not. By following up for 18 months, the survival status of the patients was documented. Kaplan-Meier method, multivariate Cox regression model, and Fine-Gray competing risk model were used to assess the relationship between sarcopenia and all-cause mortality, cardio-cerebrovascular disease mortality, and infection-related disease mortality.Results:A total of 143 MHD patients were enrolled in this study, with age of 65 (58,74) years old and 89 males (62.24%). The prevalence of sarcopenia was 25.17% (36/143). The sarcopenia group had older age ( Z=3.486, P<0.001), higher single-pool Kt/V ( Z=3.634, P<0.001), interleukin-6 ( Z=3.434, P<0.001) and extracellular water/intracellular water ratio ( Z=2.477, P=0.013), and lower body mass index ( Z=-3.210, P=0.001), serum phosphorus ( t=2.475, P=0.015), serum creatinine ( t=3.319, P=0.001), serum albumin ( t=2.851, P=0.005), serum prealbumin ( t=3.384, P<0.001), extracellular water ( Z=-5.124, P<0.001), intracellular water ( Z=-5.417, P<0.001), grip strength ( Z=-3.796, P<0.001) and appendicular skeletal muscle mass index ( t=3.862, P<0.001) than those in the non-sarcopenia group. Kaplan-Meier survival curves showed that the overall survival rate in the sarcopenia group was lower than that in the non-sarcopenia group (Log-rank test χ2=15.99, P<0.001). Multivariable Cox regression analysis demonstrated that sarcopenia was independently correlated with all-cause mortality in MHD patients after adjusting for confounding factors ( HR=2.75, 95% CI 1.07-7.10, P=0.036). Fine-Gray competing risk model result showed that there was no statistically significant difference in cardio-cerebrovascular disease mortality between sarcopenia group and non-sarcopenia group ( SHR=4.99, 95% CI 0.94-26.85, P=0.069); the risk of infection-related disease mortality in sarcopenia group was 5.76 folds than that in non-sarcopenia group ( SHR=5.76, 95% CI 1.15-28.96, P=0.034). Conclusions:There is prevalent sarcopenia in MHD patients. Moreover, sarcopenia is an independent risk factor of all-cause mortality and infection-related disease mortality in MHD patients.

Clinical efficacy of different anesthesia methods in patients with endovascular treatment for acute anterior circulation ischemic stroke: a meta-analysis / 中华神经科杂志

Objective:To systematically evaluate the efficacy and safety of general anesthesia versus conscious sedation in patients with endovascular therapy for acute ischemic stroke.Methods:Databases, including English databases PubMed, Embase and Cochrane, as well as Chinese databases Wan Fang Data and CNKI, were screened for randomized controlled trials (RCT) of general anesthesia versus conscious sedation on the effect of endovascular treatment for acute anterior circulation ischemic stroke. The searching period was from the establishment of databases to July 14, 2022. Two researchers independently screened literatures, extracted data and evaluated the risk of bias. And meta-analysis was performed using RevMan5.3 software.Results:A total of 7 RCTs involving 923 patients were included, with 461 in the general anesthesia group and 462 in the other. As the meta-analysis showing, general anesthesia could significantly improve the good outcomes (modified Rankin Scale score≤2) at 3 months after endovascular treatment in comparison with conscious sedation ( OR=1.34, 95% CI 1.01-1.78, P=0.04), and significantly increased the rate of successful revascularization ( OR=1.87, 95% CI 1.32-2.65, P<0.001). In addition, there were no statistically significant differences between the two groups in mortality ( OR=0.93, 95% CI 0.66-1.29, P=0.65), symptomatic intracranial hemorrhage ( OR=0.88, 95% CI 0.57-1.35, P=0.55) and intervention-related complications ( OR=0.83, 95% CI 0.50-1.36, P=0.46). However, general anesthesia was associated with higher risk for both 20% reduction in mean arterial pressure ( OR=4.76, 95% CI 1.49-15.19, P=0.008) and pneumonia ( OR=2.58, 95% CI 1.51-4.39, P<0.001). Conclusions:Compared with conscious sedation, endovascular treatment under general anesthesia in patients with acute anterior circulation ischemic stroke may contribute to better outcomes and higher successful revascularization. However, this method will lead to the risk of blood pressure variability and the incidence of pneumonia.

Association of different components and combinations of metabolic syndrome with hyperuricemia in community residents / 中华全科医师杂志

Objective:To explore the relationship between different components of metabolic syndrome (MS) and their combinations with hyperuricemia (HUA) in community residents.Methods:A cross-sectional survey was conducted from March to November 2020 among 10% residents aged 18 and above selected by cluster sampling method from Nanzhai Community of Taiyuan City. According to serum uric acid levels, the selected individuals were divided into HUA group and non HUA group. The general clinical data of the selected subjects was collected, and routine physical examination and laboratory tests were performed. The serum uric acid levels were detected in fasting blood samples. The association of 5 components (hypertension, hyperglycemia, abdominal obesity, hypertriglyceridemia (TG), and low high-density lipoprotein cholesterol (HDL-C)) of MS and their combinations with HUA was analyzed by multivariate logistic regression model.Results:A total of 2 167 community residents were included in the survey, there were 385 cases of HUA with the age of (49.1±15.8) years old, and 297 males (77.1%); 1 782 subjects without HUA and with the age of (48.2±16.2) years old, and 695 males (39.0%). Compared with the non HUA group, the HUA group had a higher proportion of males, smoking, alcohol consumption, and gout attacks, higher abdominal circumference and body mass index (all P<0.05). The proportion of hypertension, hypertriglyceridemia, and abdominal obesity of MS patients in the HUA group was higher, while the proportion of low HDL-C syndrome was lower (all P<0.05). However, there was no significant difference in the proportion of hyperglycemia between the two groups ( P>0.05). After adjusting for smoking, drinking alcohol, taking antihypertensive and hypoglycemic drugs, multivariate logistic regression analysis showed that except for hyperglycemia, all other components of MS were independently associated with HUA. low HDL-C was negatively associated with HUA ( OR=0.408, 95% CI: 0.231-0.721, P=0.002), and high TG was strongly associated with HUA ( OR=1.834, 95% CI: 1.339-2.513, P<0.001). Multivariate logistic regression analysis also showed that 9 out of 31 combinations of MS components were associated with HUA (all P<0.05), and abdominal obesity+hypertriglyceridemia had the strongest association with HUA ( OR=4.379, 95% CI: 2.184-8.780, P<0.001). Conclusion:Except hyperglycemia, all components of MS and their combinations are significantly associated with HUA, the association between hyper-TG and HUA is the strongest one.

Influential factors of adverse pregnancy outcome in women with subchorionic hematoma / 中国基层医药

Objective:To investigate the influential factors of adverse pregnancy outcomes in women with subchorionic hematoma.Methods:A total of 101 women with subchorionic hematoma who received treatment in the People's Hospital of Xinjiang Uygur Autonomous Region from January 2017 to June 2020 were included in this study. They were divided into a control group and an adverse pregnancy outcome group according to whether there was an adverse pregnancy outcome. The epidemiological characteristics, hematoma characteristics observed on ultrasound images, and pregnancy outcomes were compared between the two groups.Results:There was no significant difference in the number of women who used assisted reproductive technology between the control and adverse pregnancy outcome groups [6 (8.0%) vs. 8 (30.7%), χ2 = 8.38, P = 0.004]. There was a significant difference in hematoma volume between adverse pregnancy outcome and control groups [(4.12 ± 0.61) mL vs. (6.36 ± 0.87) mL, t = 6.73, P = 0.009]. There was a significant difference in the number of patients who had obstetric complications between control and adverse pregnancy outcome groups [11 (14.7%) vs. 16 (61.5%), χ2 = 21.66, P = 0.001]. There was a significant difference in the number of patients who had hematomas located at the edge of the placenta between the control and adverse pregnancy outcome groups [15 (20.0%) vs. 12 (46.2%), χ2 = -4.81, P = 0.001]. Conclusion:Women who use assisted reproductive technology for pregnancy, have obstetric complications, or have a subchorionic hematoma with hematoma at the edge of the placenta are more likely to experience a miscarriage.

An empirical research on the enrollment quality of master of stomatology professional degree graduate students—Based on the statistical data of the comprehensive evaluation of professional degree graduate students by the guiding physicians / 中华医学教育探索杂志

Objective:Based on the statistical data of the comprehensive evaluation of professional degree graduate students by the guiding physicians, to conduct an empirical study on the quality of the enrollment of master of stomatology professional degree graduate students.Methods:A total of 67 master of stomatology professional degree graduate students from Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University were comprehensively evaluated by their guiding physicians when they went out the department. SPSS 25.0 software was used for t test and variance analysis. Results:The average score of 67 students was (91.39±3.55) points. There was good reliability and validity for the comprehensive evaluation index. Among the methods of promotion and exemption, unified examination, 7-year transfer to "5 + 3" of our school and enrollment of students from Hong Kong, Macao and Taiwan regions, the comprehensive evaluation total score of 7-year transfer to "5 + 3" of our school was the highest. The comprehensive evaluation results of the students with high initial scores were slightly higher than those students with low scores. The students who studied in the "Double First-class" universities and were with the fourth round of subject assessment grade A and grade B had better performances.Conclusion:We should attach importance to enrollment quality, through various channels to attract quality students and actively explore ways to improve the quality of graduate students. Meanwhile, we should make efforts to strengthen training quality and to build scientific comprehensive evaluation system for specialized degree graduate students. The connotation of "medicine-education collaboration" will be further deepened. And the training and development of oral medicine applied high-level medical talents will be promoted.

Efficacy and safety evaluation of three medicated eye patches in Demodex blepharitis: a multicenter, double-blind, randomized controlled clinical trial / 中华实验眼科杂志

Objective:To evaluate and compare the clinical efficacy and safety of three different medicated eye patches in the treatment of Demodex blepharitis. Methods:A multicenter, randomized, double-blind, parallel-controlled clinical trial was conducted.A total of 140 patients (280 eyes) with Demodex blepharitis were recruited in Shanghai Jing'an District Shibei Hospital, Xi'an Fourth Hospital and Kunming First People's Hospital from July 2021 to December 2022.The affected eyes were randomly divided into tea tree oil group, okra oil group, basal fluid control group and metronidazole group by the random number table method.Eye patches containing 20% tea tree oil, 1% okra oil, prepared base solution and 2% metronidazole were applied to the eyes for 28 days by the double-blind method.The count of Demodex was evaluated before treatment and on days 14 and 28 of treatment.Ocular surface symptoms were scored according to Ocular Surface Disease Index (OSDI). The degree of congestion at the eyelid margin and cylindrical dandruff at the root of eyelashes were scored under a slit lamp microscope.The effective rate was calculated according to the comprehensive scores above, and the adverse reactions of the subjects were observed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Shanghai Jing'an District Shibei Hospital (No.YL-20200320-05). All the subjects were informed of the significance, purpose and method of the study.Written informed consent was obtained from each subject before any medical examination. Results:All subjects completed the treatment and follow-up, and the loss to follow-up rate was 0%.After 14 and 28 days of treatment, the Demodex count was significantly decreased in all groups compared with before treatment (all at P<0.05). After 28 days of treatment, the number of Demodex in tea tree oil group, okra oil group and metronidazole group were significantly lower than that in basal fluid control group, with statistically significant differences (all at P<0.05). The OSDI score, palpebral margin congestion score and cylindrical dandruff score on 14 and 28 days after treatment in tea tree oil group, okra oil group and metronidazole group were significantly lower than before treatment, showing statistically significant differences (all at P<0.05). After 28 days of treatment, the effective rates of tea tree oil group, okra oil group and metronidazole group were 71.4%, 71.4% and 62.9%, respectively, which were significantly higher than 25.7% in basal solution control group.No serious local or systemic adverse reactions were found during the treatment and follow-up. Conclusions:Eye patches containing tea tree oil, okra oil and metronidazole have significant effects on the treatment of Demodex blepharitis, which can improve the biological environment of the palpebral margin and eliminate the inflammation related to blepharitis.
