Effect of Qihuang Jianpi Zishen Granules on STAT3/mTOR Signaling Pathway in Patients with Systemic Lupus Erythematosus / 中国实验方剂学杂志

ObjectiveTo investigate the clinical efficacy of Qihuang Jianpi Zishen Granules in the treatment of systemic lupus erythematosus （SLE） and its effect on the signal transducer and activator of tranSCription 3/mammalian target of rapamycin （STAT3/mTOR） signaling pathway， and to decipher the possible mechanism. MethodSixty female SLE patients who met the criteria in the First Affiliated Hospital of Anhui University of Chinese Medicine from May 2022 to May 2023 were selected and randomized into a control group and an observation group （30 cases in each group）. The control group was treated with prednisone acetate + hydroxychloroquine sulfate orally， and the observation group was additionally treated with Qihuang Jianpi Zishen granules. The treatment lasted for 8 weeks. The SLE disease activity （SLEDAI）， TCM syndrome score， erythrocyte sedimentation rate （ESR）， hypersensitive C-reactive protein （hs-CRP）， immune indexes ［immunoglobulin G （IgG）， C3， C4， CD4+， and CD8+］， interleukin （IL）-17， IL-23， interferon （IFN）-γ， 24 h urinary protein （24 h PRO）， serum creatinine （SCr）， and expression of proteins ［STAT3， phosphorylated （p）-STAT3， mTOR protein and STAT3，mTOR mRNA］ in the STAT3/mTOR signaling pathway were determined before and after treatment. In addition， the adverse reactions were recorded. ResultAfter 8 weeks of treatment， the total response rate in the observation group was 93.33% （28/30）， which was higher than that （70.00%， 21/30） in the control group （χ2=4.007， P<0.05）. After treatment， both groups showed declined SLEDAI， TCM syndrome score， ESR， hs-CRP， IgG， CD8+， IL-17， IL-23， IFN-γ， 24 h PRO， SCr， and expression of proteins in the STAT3/mTOR pathway （P<0.01） and elevated levels of C3， C4， and CD4+ （P<0.01）. Moreover， the observation group had lower SLEDAI， TCM syndrome score， ESR， hs-CRP， IgG， CD8+， IL-17， IL-23， IFN-γ， 24 h PRO， SCr， and expression of proteins in the STAT3/mTOR pathway （P<0.05， P<0.01） and higher levels of C3， C4， and CD4+ （P<0.05， P<0.01） than the control group after treatment. Neither group showed serious adverse reactions during the treatment period. ConclusionQihuang Jianpi Zishen Granules can ameliorate the inflammatory response， reduce the disease activity， and mitigate the kidney injury in SLE by inhibiting the STAT3/mTOR signaling pathway to regulate the immune function.

Imaging study on thoracic and lumbar physiological curvature in adolescent idiopathic scoliosis / 中国骨伤

OBJECTIVE@#To observe the alteration of thoracic and lumbar physiological curvature in adolescent idiopathic scoliosis(AIS) and the difference of physiological curvature between different types of scoliosis.@*METHODS@#A retrospective analysis was conducted on 305 adolescent patients taken full spine X-ray in our hospital from January 2017 to December 2021. The patients were divided into normal group and scoliosis group. The normal group was composed of 179 patients, 79 males and 100 females, aged 10 to 18 years old with an average of (12.84±2.10) years old, with cobb agle less than 10 degrees. The scoliosis group was composed of 126 patients, 33 males and 93 females, aged 10 to 18 years old with an average of (13.92±2.20) years old. The gender, age, Risser sign, thoracic kyphosis(TK) and lumbar lordosis(LL) in 2 groups were compared, and the TK and LL were also compared between different genders, different degrees of scoliosis and different segments of scoliosis.@*RESULTS@#The female ratio(P=0.001) and age (P<0.001) in scoliosis group were higher than them in normal group; the ratio of low-grade ossification was higher in normal group than in scoliosis group(P=0.038). TK was significantly smaller in scoliosis group than in normal group(P<0.001), but there was no significant difference in LL between the 2 groups(P=0.147). There were no significant difference in TK and LL between male and female. The TK was significantly bigger in mild AIS patients than in moderate AIS patients(P<0.05), but there was no significant difference in LL between mild and moderate patients(P>0.05). The TK and LL in different segments scoliosis were not found significant difference.@*CONCLUSION@#The physiological curvature of thoracic and lumbar spine is independent of gender. The thoracic physiological curvature becomes smaller in AIS patients, but lumbar curvature remains unchanged. The thoracic physiological curvature in mild AIS patients is greater than that in moderate AIS patients, but the lumbar curvature is almost unchanged between mild and moderate scoliosis and is similar with that in normal adolescent. The alteration of thoracic and lumbar physiological curvature in AIS patients may be related to relative anterior spinal overgrowth, and the specific detailed mechanism needs to be further studied.

Application of different prognostic scores in liver transplantation decision-making for acute-on-chronic liver failure / 中华肝脏病杂志

Objective: To compare the impact of different prognostic scores in patients with acute-on-chronic liver failure (ACLF) in order to provide treatment guidance for liver transplantation. Methods: The information on inpatients with ACLF admitted at Beijing You'an Hospital Affiliated to Capital Medical University and the First Affiliated Hospital of Zhejiang University School of Medicine from January 2015 to October 2022 was collected retrospectively. ACLF patients were divided into liver transplantation and non-liver transplantation groups, and the two groups prognostic conditions were followed-up. Propensity score matching was carried out between the two groups on the basis of liver disease (non-cirrhosis, compensated cirrhosis, and decompensated cirrhosis), the model for end-stage liver disease incorporating serum sodium (MELD-Na), and ACLF classification as matching factors. The prognostic condition of the two groups after matching was compared. The difference in 1-year survival rate between the two groups was analyzed under different ACLF grades and MELD-Na scores. The independent sample t-test or rank sum test was used for inter-group comparison, and the χ (2) test was used for the comparison of count data between groups. Results: In total, 865 ACLF inpatients were collected over the study period. Of these, 291 had liver transplantation and 574 did not. The overall survival rates at 28, 90, and 360 days were 78%, 66%, and 62%, respectively. There were 270 cases of matched ACLF post-liver transplantation and 270 cases without ACLF, in accordance with a ratio of 1:1. At 28, 90, and 360 days, patients with non-liver transplantation had significantly lower survival rates (68%, 53%, and 49%) than patients with liver transplantation (87%, 87%, and 78%, respectively; P < 0.001). Patients were classified into four groups according to the ACLF classification criteria. Kaplan-Meier survival analysis showed that the survival rates of liver transplantation and non-liver transplantation patients in ACLF grade 0 were 77.2% and 69.4%, respectively, with no statistically significant difference (P = 0.168). The survival rate with an ACLF 1-3 grade was significantly higher in liver transplantation patients than that of non-liver transplantation patients (P < 0.05). Patients with ACLF grades 1, 2, and 3 had higher 1-year survival rates compared to non-liver transplant patients by 50.6%, 43.6%, and 61.7%, respectively. Patients were divided into four groups according to the MELD-Na score. Among the patients with a MELD-Na score of < 25, the 1-year survival rates for liver transplantation and non-liver transplantation were 78.2% and 74.0%, respectively, and the difference was not statistically significant (P = 0.149). However, among patients with MELD-Na scores of 25-30, 30-35, and≥35, the survival rate was significantly higher in liver transplantation than that of non-liver transplantation, and the 1-year survival rate increased by 36.4%, 54.9%, and 62.5%, respectively (P < 0.001). Further analysis of the prognosis of patients with different ACLF grades and MELD-Na scores showed that ACLF grades 0 or 1 and MELD-Na score of < 30 had no statistically significant difference in the 1-year survival rate between liver transplantation and non-liver transplantation (P > 0.05), but in patients with MELD-Na score≥30, the 1-year survival rate of liver transplantation was higher than that of non-liver transplantation patients (P < 0.05). In the ACLF grade 0 and MELD-Na score of≥30 group, the 1-year survival rates of liver transplantation and non-liver transplantation patients were 77.8% and 25.0% respectively (P < 0.05); while in the ACLF grade 1 and MELD-Na score of≥30 group, the 1-year survival rates of liver transplantation and non-liver transplantation patients were 100% and 20.0%, respectively (P < 0.01). Among patients with ACLF grade 2, the 1-year survival rate with MELD-Na score of < 25 in patients with liver transplantation was 73.9% and 61.6%, respectively, and the difference was not statistically significant (P > 0.05); while in the liver transplantation patients group with MELD-Na score of ≥25, the 1-year survival rate was 79.5%, 80.8%, and 75%, respectively, which was significantly higher than that of non-liver transplantation patients (36.6%, 27.6%, 15.0%) (P < 0.001). Among patients with ACLF grade 3, regardless of the MELD-Na score, the 1-year survival rate was significantly higher in liver transplantation patients than that of non-liver transplantation patients (P < 0.01). Additionally, among patients with non-liver transplantation with an ACLF grade 0~1 and a MELD-Na score of < 30 at admission, 99.4% survived 1 year and still had an ACLF grade 0-1 at discharge, while 70% of deaths progressed to ACLF grade 2-3. Conclusion: Both the MELD-Na score and the EASL-CLIF C ACLF classification are capable of guiding liver transplantation; however, no single model possesses a consistent and precise prediction ability. Therefore, the combined application of the two models is necessary for comprehensive and dynamic evaluation, but the clinical application is relatively complex. A simplified prognostic model and a risk assessment model will be required in the future to improve patient prognosis as well as the effectiveness and efficiency of liver transplantation.

Clinical features and prognosis of 118 children with histiocytic necrotizing lymphadenitis / 中华儿科杂志

Objective: To explore the clinical features and prognosis of children with histiocytic necrotizing lymphadenitis (HNL). Methods: The clinical data of 118 children with HNL diagnosed and treated in the Department of Rheumatology and Immunology of Children's Hospital, Capital Institute of Pediatrics from January 2014 to December 2021 were retrospectively analyzed. The clinical symptoms, laboratory examination, imaging examination, pathological findings, treatment and follow-up were analyzed. Results: Among the 118 patients, 69 were males and 49 were females. The age of onset was 10.0 (8.0, 12.0) years, ranging from 1.5 to 16.0 years. All the children had fever lymph node enlargement, blood system involvement in 74 cases (62.7%), skin injury in 39 cases (33.1%). The main manifestations of laboratory examination were increased erythrocyte sedimentation rate in 90 cases (76.3%), decreased hemoglobin in 58 cases (49.2%), decreased white blood cells in 54 cases (45.8%) and positive antinuclear antibody in 35 cases (29.7%). Ninety-seven cases (82.2%) underwent B-mode ultrasound of lymph nodes, showing nodular lesions with low echo in the neck; 22 cases (18.6%) underwent cervical X-ray and (or) CT; 7 cases (5.9%) underwent cervical magnetic resonance imaging. Lymph node biopsy was performed in all 118 cases, and the pathological results did not support malignant diseases such as lymphoma or Epstein-Barr virus infection, suggesting HNL. Fifty-seven cases (48.3%) recovered without treatment, 61 cases (51.7%) received oral steroid therapy, and 4 cases (3.4%) received indomethacin as anal stopper. The 118 cases were followed up for 4 (2, 6) years, ranging from 1 to 7 years, 87 cases (73.7%) had one onset and did not develop into other rheumatological diseases, and 24 cases (20.3%) had different degrees of recurrence, 7 cases (5.9%) had multiple system injuries, and all of the tested autoantibodies were positive for medium and high titers. All of them developed into other rheumatic immune diseases, among which 5 cases developed into systemic lupus erythematosus and 2 cases developed into Sjogren's syndrome; 7 cases were given oral steroid therapy, including 6 cases plus immunosuppressant and 2 cases receiving methylprednisolone 20 mg/kg shock therapy. Conclusions: The first-onset HNL portion is self-healing, hormone-sensitive and has a good prognosis. For HNL with repeated disease and multiple system injury, antinuclear antibody titer should be monitored during follow-up, and attention should be paid to the possibility of developing into other rheumatological diseases, with poor prognosis.

HIV testing is the only way to identify HIV-infection, effectively curb the spread of HIV and reduce AIDS-related death risks. At present, the situation of HIV testing in MSM is not satisfactory, and expanding HIV testing is the one of the key measures for AIDS prevention and control in this population. This paper summarizes the role and strategies of expanding HIV testing in MSM in order to provide a reference for the improvement of HIV testing in this population.

Progress on genome-wide association studies on mosaic chromosomal alterations / 中华流行病学杂志

Mosaic chromosomal alteration (mCA) is referred to as large-scale somatic mutations on chromosomes, which results in diverse karyotypes in body. The mCA is regarded as one of the phenotypes of aging. Studies have revealed its associations with many chronic diseases such as hematopoietic cancers and cardiovascular diseases, but its genetic basis (e.g. genetic susceptibility variants) is still under-investigated. This paper reviews GWAS studies for mCA on autosomal chromosomes and sex chromosomes [mosaic loss of the Y chromosome (mLOY) and mosaic loss of the X chromosome (mLOX)] based on large population, respectively. Most of the genetic susceptibility loci found in studies for autosomal mCA were associated with copy-neutral loss of heterozygosity. The study of sex chromosome mCA focused on mosaic loss mutations. The number of genetic susceptibility loci for mLOY was high (up to 156), but it was relatively less for mLOX.

Tea consumption and cancer: a Mendelian randomization study / 中华流行病学杂志

Objective: A Mendelian randomization (MR) analysis was performed to assess the relationship between tea consumption and cancer. Methods: There were 100 639 participants with the information of gene sequencing of whole genome in the China Kadoorie Biobank. After excluding those with cancer at baseline survey, a total of 100 218 participants were included in this study. The baseline information about tea consumption were analyzed, including daily tea consumption or not, cups of daily tea consumption, and grams of daily tea consumption. We used the two-stage least square method to evaluate the associations between three tea consumption variables and incidence of cancer and some subtypes, including stomach cancer, liver and intrahepatic bile ducts cancer, colorectal cancer, tracheobronchial and lung cancer, and female breast cancer. Multivariable MR and analysis only among nondrinkers were used to control the impact of alcohol consumption. Sensitivity analyses were also performed, including inverse variance weighting, weighted median, and MR-Egger. Results: We used 54, 42, and 28 SNPs to construct non-weighted genetic risk scores as instrumental variables for daily tea consumption or not, cups of daily tea consumption, and grams of daily tea consumption, respectively. During an average of (11.4±3.0) years of follow-up, 6 886 cases of cancer were recorded. After adjusting for age, age2, sex, region, array type, and the first 12 genetic principal components, there were no significant associations of three tea consumption variables with the incidence of cancer and cancer subtypes. Compared with non-daily tea drinkers, the HR (95%CI) of daily tea drinkers for cancer and some subtypes, including stomach cancer, liver and intrahepatic bile ducts cancer, colorectal cancer, tracheobronchial and lung cancer, and female breast cancer, are respectively 0.99 (0.78-1.26), 1.17 (0.58-2.36), 0.86 (0.40-1.84), 0.85 (0.42-1.73), 1.39 (0.85-2.26) and 0.63 (0.28-1.38). After controlling the impact of alcohol consumption and performing multiple sensitivity analyses, the results were similar. Conclusion: There is no causal relationship between tea consumption and risk of cancer in population in China.

Epidemiological distribution characteristics of peripheral blood mosaic chromosomal alteration in adults from 10 regions of China / 中华流行病学杂志

Objective: To describe the epidemiological distribution characteristics of peripheral blood mosaic chromosomal alteration (mCA) in community adults aged 30-79 years in 10 regions of China. Methods: A total of 100 297 participants with complete baseline information (demographic characteristics, lifestyle, physical examination, etc.) and genotyping data of blood-derived DNA in ten regions of the China Kadoorie Biobank study were included. The mCAs were detected with the Mosaic Chromosomal Alterations pipeline, and logistic regression models were used to compare the differences in the detection rate of mCAs in different regions and populations. Results: A total of 5 810 mCA carriers were detected, with the detection rate of 5.8%. The standardized detection rate was 5.1%. The baseline detection rate of mCA increased with age, which were 3.4%, 5.0%, and 9.4% in those aged 30-, 51-, and >60 years, respectively (trend test P<0.001). A more significant proportion of mCAs were found in men (8.0%) than women (4.0%), as well as in urban areas (6.4%) than in rural areas (5.3%), the difference was significant (P<0.001). After adjusting for age and gender, the detection rate of mCA was higher in current smokers or people quitting smoking due to illness and people with low physical activity level, and the mCA detection rate was lower in obesy people (5.3%) than that in people with normal body weight (5.9%) (P=0.006). Conclusions: The detection rate of mCAs varied with region and population in community adults aged 30-79 years in 10 regions of China. The study results might contribute to the molecular identification of aging populations and guide precision prevention of age-related diseases such as cancers.

A review on cardiovascular disease risk prediction models in the elderly / 中华流行病学杂志

Risk prediction models play an important role in the primary prevention of cardiovascular diseases (CVD) in the elderly population. There are fifteen papers about CVD risk prediction models developed for the elderly domestically and internationally, of which the definitions of disease outcome vary widely. Ten models were reported with insufficient information about study methods or results. Ten models were at high risk of bias. Thirteen models presented moderate discrimination in internal validation, and only four models have undertaken external validation. The CVD risk prediction models for the elderly differed from those for the general population in terms of model algorithm and the effect size of association between predictor and outcome, and the prediction performance of the models for the elderly attenuated. In the future, high-quality external validation researches are necessary to provide more solid evidence. Different ways, including adding new predictors, using competing risk model algorithms, machine learning methods, or joint models, and altering the prediction time horizon, should be explored to optimize the current models.

A case-control study on the association between a healthy lifestyle and obesity among adult twins in Shanghai / 中华流行病学杂志

Objective: To investigate the associations between the numbers of healthy lifestyles and overweight/obesity and abdominal obesity in adult twins in Shanghai. Methods: Based on the Shanghai Twin Registry System Phase Ⅱ survey data in 2017-2018, a case-control study was conducted to analyze the association between healthy lifestyles and obesity and further adjusted for confounders by a co-twin control study. Results: A total of 7 864 adult twins (3 932 pairs) were included. In the co-twin case-control analysis for monozygotic twins, compared with participants with 0 to 2 healthy lifestyles, those with 3 and 4 to 5 healthy lifestyles had a 49% (OR=0.51, 95%CI: 0.28-0.93) and 70% (OR=0.30, 95%CI: 0.13-0.69) lower risk of overweight/obesity, respectively, and a 17% (OR=0.83, 95%CI: 0.44-1.57) and 66% (OR=0.34, 95%CI: 0.14-0.80) lower risk of abdominal obesity, respectively. For each additional healthy lifestyle, the risk of developing overweight/obesity was reduced by 41% (OR=0.59, 95%CI: 0.42-0.85), and the risk of developing abdominal obesity was reduced by 37% (OR=0.63, 95%CI: 0.44-0.90). Conclusion: An increasing number of healthy lifestyles was associated with a marked decreased risk for both overweight/obesity and abdominal obesity.

Prospective association between physical activity and mortality in patients with chronic kidney disease / 中华流行病学杂志

Objective: To investigate the prospective association of physical activity with all-cause, cardiovascular disease (CVD), and chronic kidney disease (CKD) mortality in CKD patients in China. Methods: Cox proportional hazard models were used to evaluate the association of total, domain-specific, and intensity-specific physical activity with the risk of all-cause, CVD, and CKD mortality based on data from the baseline survey of China Kadoorie Biobank. Results: During a median follow-up of 11.99 (11.13, 13.03) years, there were 698 deaths in 6 676 CKD patients. Compared with the bottom tertile of total physical activity, participants in the top tertile had a lower risk of all-cause, CVD, and CKD mortality, with hazard ratios (HRs) (95%CIs) of 0.61 (0.47-0.80), 0.40 (0.25-0.65), and 0.25 (0.07-0.85), respectively. Occupational, commuting, and household physical activity were negatively associated with the risk of all-cause and CVD mortality to varying degrees. Participants in the top tertile of occupational physical activity had a lower risk of all-cause (HR=0.56, 95%CI: 0.38-0.82) and CVD (HR=0.39, 95%CI: 0.20-0.74) mortality, those in the top tertile of commuting physical activity had a lower risk of CVD mortality (HR=0.43, 95%CI: 0.22-0.84), and those in the top tertile of household physical activity had a lower risk of all-cause (HR=0.61, 95%CI: 0.45-0.82), CVD (HR=0.44, 95%CI: 0.26-0.76) and CKD (HR=0.03, 95%CI: 0.01-0.17) mortality, compared with the bottom tertile of corresponding physical activity. No association of leisure-time physical activity with mortality was observed. Both low and moderate-vigorous intensity physical activity were negatively associated with the risk of all-cause, CVD and CKD mortality. The corresponding HRs (95%CIs) were 0.64 (0.50-0.82), 0.42 (0.26-0.66) and 0.29 (0.10-0.83) in the top tertile of low intensity physical activity, and the corresponding HRs (95%CIs) were 0.63 (0.48-0.82), 0.39 (0.24-0.64) and 0.23 (0.07-0.73) in the top tertile of moderate-vigorous intensity physical activity. Conclusion: Physical activity can reduce the risk of all-cause, CVD, and CKD mortality in CKD patients.

A descriptive analysis of hyperlipidemia in adult twins in China / 中华流行病学杂志

Objective: To describe the distribution characteristics of hyperlipidemia in adult twins in the Chinese National Twin Registry (CNTR) and explore the effect of genetic and environmental factors on hyperlipidemia. Methods: Twins recruited from the CNTR in 11 project areas across China were included in the study. A total of 69 130 (34 565 pairs) of adult twins with complete information on hyperlipidemia were selected for analysis. The random effect model was used to characterize the population and regional distribution of hyperlipidemia among twins. The concordance rates of hyperlipidemia were calculated in monozygotic twins (MZ) and dizygotic twins (DZ), respectively, to estimate the heritability. Results: The age of all participants was (34.2±12.4) years. This study's prevalence of hyperlipidemia was 1.3% (895/69 130). Twin pairs who were men, older, living in urban areas, married,had junior college degree or above, overweight, obese, insufficient physical activity, current smokers, ex-smokers, current drinkers, and ex-drinkers had a higher prevalence of hyperlipidemia (P<0.05). In within-pair analysis, the concordance rate of hyperlipidemia was 29.1% (118/405) in MZ and 18.1% (57/315) in DZ, and the difference was statistically significant (P<0.05). Stratified by gender, age, and region, the concordance rate of hyperlipidemia in MZ was still higher than that in DZ. Further, in within-same-sex twin pair analyses, the heritability of hyperlipidemia was 13.04% (95%CI: 2.61%-23.47%) in the northern group and 18.59% (95%CI: 4.43%-32.74%) in the female group, respectively. Conclusions: Adult twins were included in this study and were found to have a lower prevalence of hyperlipidemia than in the general population study, with population and regional differences. Genetic factors influence hyperlipidemia, but the genetic effect may vary with gender and area.

A descriptive analysis on hypertension in adult twins in China / 中华流行病学杂志

Objective: To describe the distribution characteristics of hypertension among adult twins in the Chinese National Twin Registry (CNTR) and to provide clues for exploring the role of genetic and environmental factors on hypertension. Methods: A total of 69 220 (34 610 pairs) of twins aged 18 and above with hypertension information were selected from CNTR registered from 2010 to 2018. Random effect models were used to describe the population and regional distribution of hypertension in twins. To estimate the heritability, the concordance rates of hypertension were calculated and compared between monozygotic twins (MZ) and dizygotic twins (DZ). Results: The age of all participants was (34.1±12.4) years. The overall self-reported prevalence of hypertension was 3.8%(2 610/69 220). Twin pairs who were older, living in urban areas, married, overweight or obese, current smokers or ex-smokers, and current drinkers or abstainers had a higher self-reported prevalence of hypertension (P<0.05). Analysis within the same-sex twin pairs found that the concordance rate of hypertension was 43.2% in MZ and 27.0% in DZ, and the difference was statistically significant (P<0.001). The heritability of hypertension was 22.1% (95%CI: 16.3%- 28.0%). Stratified by gender, age, and region, the concordance rate of hypertension in MZ was still higher than that in DZ. The heritability of hypertension was higher in female participants. Conclusions: There were differences in the distribution of hypertension among twins with different demographic and regional characteristics. It is indicated that genetic factors play a crucial role in hypertension in different genders, ages, and regions, while the magnitude of genetic effects may vary.

Clinical Efficacy of Qihuang Jianpi Zishen Granules in Treating Cardiac Involvement in Systemic Lupus Erythematosus / 中国实验方剂学杂志

ObjectiveTo investigate the clinical efficacy and safety of Qihuang Jianpi Zishen granules in the treatment of cardiac involvement in systemic lupus erythematosus （SLE）. MethodA total of 62 SLE patients with cardiac involvement treated in the Department of Rheumatology and Immunology， the First Affiliated Hospital of Anhui University of Chinese Medicine from June 2021 to December 2022 were randomized into control and observation groups （n=31）. The control group was treated with methylprednisolone tablets and hydroxychloroquine sulfate tablets， and the observation group with Qihuang Jianpi Zishen granules on the basis of the therapy in the control group. After 12 weeks of treatment， the two groups were compared in terms of the therapeutic effect， cardiac function indicators ［left atrial end-diastolic diameter （LADd）， left ventricular end-diastolic diameter （LVDd）， left ventricular posterior wall thickness （LVPWTd）， peak blood flow velocity in early diastolic period （peak E）， peak blood flow velocity in late diastolic period （peak A）， E/A ratio， stroke volume （SV）， left ventricular ejection fraction （LVEF）， left ventricular short axis shortening rate （LVFS）， and B-type natriuretic peptide （BNP）］， vascular damage indicators ［nitric oxide （NO）， endothelin-1 （ET-1）， vascular endothelial growth factor （VEGF）， and homocysteine （Hcy）］， inflammation indicators ［erythrocyte sedimentation rate （ESR） and hypersensitive C-reactive protein （Hs-CRP）］， anti-double-stranded DNA （dsDNA） antibodies， disease activity index （SLEDAI） score， mitigation of symptoms and signs， and occurrence of adverse reactions. ResultThe total response rate in the observation group was 87.09%， which was higher than that （67.74%） in the control group （P<0.01）， and the incidence of adverse reactions had no significant difference between the two groups. After treatment， the control group showed lowered LVDd， LVPWTd， BNP， ET-1， VEGF， and Hcy （P<0.05） and increased E peak， E/A ratio， SV， LVEF， and LVFS （P<0.05）. In the observation group， LADd， LVDd， LVPWTd， peak A， BNP， NO， ET-1， VEGF， and Hcy decreased （P<0.05）， while peak E， E/A ratio， SV， LVEF and LVFS increased （P<0.05） after treatment. The treatment in both groups decreased the scores of palpitation， chest tightness， dyspnea， and edema （P<0.05）， reduced ESR， Hs-CRP， ds-DNA， and SLEDAI （P<0.05）. After treatment， the observation group had lower LADd， LVDd， LVPWTd， peak A， BNP， and scores of palpation， chest tightness， dyspnea， and edema （P<0.05） and higher peak E， E/A ratio， SV， LVEF， and LVFS （P<0.05） than the control group. In addition， the observation group had lower NO， ET-1， VEGF， Hcy， ESR， Hs-CRP， ds-DNA， and SLEDAI than the control group （P<0.05）. ConclusionQihuang Jianpi Zishen granules combined with hydroxychloroquine sulfate and methylprednisolone can improve multiple indicators and mitigate the symptoms and signs of SLE patients with cardiac involvement， demonstrating a clinical application value.

Analysis of risk factors affecting in-hospital mortality in patients with acute mesenteric ischemia / 中华消化杂志

Objective:To investigate the risk factors affecting in-hospital mortality in patients with acute mesenteric ischemia (AMI).Methods:From January 1, 2014 to June 30, 2022, the clinical data of 67 patients diagnosed with AMI at Renmin Hospital of Wuhan University were retrospectively analyzed, which included basic data (age, gender, past medical history and comorbidities, etc.), laboratory results (white blood cell count (WBC), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, prothrombin time (PT), etc.), and imaging manifestations (intestinal pneumatosis, intestinal wall thickening, intestinal dilation, ascites). The clinical data of AMI patients who died during hospitalization were compared with that of AMI patients who survived. Binary logistic regression was used to analyze the independent risk factors of in-hospital mortality in patients with AMI. Mann-Whitney U test and chi-square test were used for statistical analysis. Results:Among the 67 patients with AMI, 17 died and 50 survived. There were significant differences between died and survived patients with AMI in age, the proportion of patients with organ failure, WBC, ALT, AST, creatinine, PT, and the proportion of patients with intestinal dilatation and ascites (76 years old(68 years old, 79 years old) vs. 61 years old (50 years old, 74 years old), 12/17 vs.12.0%(6/50), 15.8×10 9/L(13.5×10 9/L, 23.7×10 9/L) vs. 12.1×10 9/L (9.1×10 9/L, 19.4×10 9/L), 32.0 U/L(19.0 U/L, 88.5 U/L) vs. 20.5 U/L(14.8 U/L, 29.0 U/L), 64.0 U/L(33.8 U/L, 117.0 U/L) vs. 26.0 U/L (18.5 U/L, 36.8 U/L), 135.0 μmol/L(61.5 μmol/L, 198.5 μmol/L) vs. 73.5 μmol/L(60.5 μmol/L, 85.0 μmol/L), 13.7 s(12.9 s, 16.3 s) vs. 12.7 s (11.9 s, 13.6 s), 13/17 vs. 38.0%(19/50), 10/17 vs. 24.0% (12/50); Z=3.06, χ2=22.16, Z=2.01, 2.69, 4.08, 2.45 and 2.78, χ2=7.53 and 6.98; P=0.002, <0.001, =0.044, =0.007, <0.001, =0.014, =0.006, =0.006 and =0.008). The results of binary logistic regression analysis showed that age ( OR=1.224, 95% confidence interval 1.011 to 1.482, P=0.038), organ failure ( OR=113.989, 95% confidence interval 1.353 to 9 604.644, P=0.036), and ascites ( OR=348.289, 95% confidence interval 1.676 to 72 357.934, P=0.032) were independent risk factors of in-hospital mortality in AMI patients. Conclusion:Age, organ failure and ascites are independent risk factors of in-hospital mortality in AMI patients.

The clinical effect of combining electroacupuncture with long needle sacral nerve stimulation in the treatment of diabetic overactive bladder / 中华物理医学与康复杂志

Objective:To observe the clinical efficacy of combining electroacupuncture with long needle sacral nerve acupuncture in the treatment of diabetic overactive bladder.Methods:A total of 90 patients with diabetic overactive bladder were randomly divided into an observation group and a control group, each of 45. In addition to the basic treatment for diabetes, the observation group received electroacupuncture combined with long needle sacral nerve acupuncture 5 times a week for 4 weeks, while the control group was given 5mg of oral solinax succinate once a day as a course of treatment. One week before the beginning of the experiment and one week before its end, urination diary cards were used to record the average number of times of daytime and nighttime urination daily, as well as any urgent urination and urinary incontinence during the week. Bladder overactivity syndrome score (OABSS), the bladder overactivity quality of life questionnaire (OAB-q), maximum urine flow rate (Qmax) and mean urine flow rate (Qave) were employed to quantify urination status, life quality and the urodynamics of the 2 groups before and after the treatment.Results:After the treatment, significant improvement was observed in the average weekly incidence of daytime and nighttime urination, of urgent urination and of urinary incontinence. The average OABSS, OAB-q, Qmax and Qave scores improved in both groups, but the experimental group showed significantly better improvement than the control group.Conclusion:Electroacupuncture combined with sacral nerve needling can significantly reduce the frequency of urination, relieve the symptoms of urgent urination and incontinence, and improve the rate of urine flow, improving the life quality of patients with diabetic overactive bladder.
