Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition， concoction， decoction， efficacy， and previous and modern application of Sangjuyin. After examination， the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris， family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa， family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx， family Labiatae. Mori Folium is the dried leaves of Morus alba， family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium， family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum， family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family， and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum， 5.60 g Forsythiae Fructus， 2.98 g Menthae Haplocalycis Herba， 9.33 g Mori Folium， 3.73 g Chrysanthemi Flos， 7.46 g Platycodonis Radix， 2.98 g Glycyrrhizae Radix et Rhizoma， and 11.19 g Phragmitis Rhizoma， with 400 mL water added， and the solution was boiled to obtain 200 mL， taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat， promoting lung and relieving cough， and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough， pneumonia， rhinitis， and other respiratory diseases， and the results of this study provide a reference for the later development of Sangjuyin.

BACKGROUND:Sarcopenia is an age-related systemic skeletal muscle disease,which is associated with a variety of adverse outcomes such as falls,functional decline,frailty,and death.Postmenopausal women are one of the high-risk groups for sarcopenia.OBJECTIVE:To develop a predictive model for assessing the risk of sarcopenia in Chinese postmenopausal women based on high-quality database.METHODS:Data for this study were derived from 2 370 postmenopausal women from the China Health and Retirement Longitudinal Study(CHARLS),and sarcopenia was assessed using the Asian Working Group on Sarcopenia 2019(AWGS2019)recommended metrics.The study cohort was randomized into a training set(70％)and a validation set(30％).Risk factors for sarcopenia in postmenopausal women were screened using the least absolute shrinkage and selection operator,ten-fold cross-validation,and logistic regression.Nomogram predicting the risk of sarcopenia in postmenopausal women was constructed based on the risk factors,and the model efficacy was evaluated by the receiver operating characteristic curve and area under the curve(AUC),calibration curve,and decision curve analysis.RESULTS AND CONCLUSION:The prevalence of sarcopenia in this study was 23.50％and age,place of residence,sleep quality,cognitive function,depression,and the number of chronic diseases were selected as predictors of sarcopenia in postmenopausal women.The nomogram model showed good discrimination between the training and validation sets,with an AUC value of 0.751(95％confidence interval=0.724-0.778,P＜0.001),a specificity of 72.2％,and a sensitivity of 63.2％in the training set,and an AUC value of 0.763(95％confidence interval=0.721-0.805,P＜0.001),with a specificity of 69.6％and a sensitivity of 70.8％.The calibration curve showed a relatively significant agreement between the nomogram model and the actual observations,and the decision curve analysis demonstrated broad and good clinical utility.To conclude,the nomogram to assess the risk of sarcopenia constructed based on age,place of residence,sleep quality,cognitive function,depression,and number of chronic diseases,provides an effective tool for identifying and eliminating risk factors for sarcopenia in Chinese postmenopausal women,and helps to reduce the incidence of sarcopenia.

Objective: To understand the awareness of chikungunya fever knowledge and its related factors among medical college students in Baise City, so as to provide a scientific basis to offer relevant courses and special education. Methods: From July to August 2025, 7 286 enrolled medical students were selected by a sampling method from a medical college in Baise City to participate in the questionnaire survey. The questionnaire covered epidemiological characteristics, clinical symptoms, and prevention/control knowledge of chikungunya fever. Statistical analyses including the Chi quare test and multivariate Logistic regression models were performed. Results: The overall awareness rate of chikungunya fever knowledge among the medical students was 18.89%. Among the knowledge items, the awareness rate of "the high incidence season" was the highest (84.05%), while that of "the infectious period" was the lowest (17.80%). Multivariate Logistic regression analysis showed that medical students with female (a OR= 1.37 , 95%CI =1.20- 1.57 ), the age for over 25 years old (a OR=1.76, 95%CI =1.05-2.93), whose father had a middle school educational level (a OR=1.18, 95%CI =1.05-1.31), and majored in preventive medicine (a OR=1.54, 95%CI =1.10-1.67) had relatively higher awareness rates of chikungunya fever knowledge (all P <0.05). In contrast, students of Zhuang ethnicity (a OR= 0.87 , 95%CI =0.76-0.98) and majoring in nursing (a OR=0.74, 95%CI =0.61-0.91) or pharmacy (a OR=0.70, 95%CI =0.52-0.95) had relatively lower awareness rates (all P <0.05). Conclusions The awareness rate of chikungunya fever related knowledge among medical college students in Baise City is relatively low. Schools should take targeted publicity measures to improve medical students awareness.

BACKGROUND:Fixed-point rotation manipulation of cervical spine is a mechanical operation with high technical requirements,but the biomechanics of fixed-point manipulation of cervical spine still lacks relevant quantitative data.Moreover,the research on the influencing factors of cervical fixed-point rotation manipulation includes many parameters and there are differences,so it is necessary to further analyze its influencing factors to improve its related data. OBJECTIVE:To quantify the biomechanical parameters of cervical spine fixed-point rotation manipulation,explore the correlation between different biomechanical parameters,and the influence of individual characteristics of the subjects on the biomechanical parameters of cervical spine fixed-point rotation manipulation. METHODS:Totally 35 cases of cervical spondylosis were Outpatients from Orthopedic Department of Renai Branch of the First Affiliated Hospital of Guangxi University of Chinese Medicine and selected as the subjects investigated.Wearable mechanical measuring gloves were used to collect biomechanical parameters of cervical spine fixed-point rotation manipulation,including:thumb preload,thumb maximum thrust,palm preload,palm wrench force,and palm wrench maximum force.Personal characteristic parameters were collected,including age,height,weight,and neck circumference.The key biomechanical parameters in the process of cervical spine fixed-point rotation manipulation were analyzed and different individual characteristics were quantified.The results of biomechanical parameters were analyzed using Spearman correlation analysis.The possible effects of different individual characteristic parameters on biomechanics were analyzed. RESULTS AND CONCLUSION:(1)Compared with bilateral mechanical parameters,there was no significant difference between left manipulation and right manipulation(P>0.05).(2)The average of thumb preload force was(7.21±1.19)N;the average of thumb maximum thrust was(28.40±4.48)N;the average of palm preload was(5.67±2.49)N;the average of palm wrench force was(10.90±5.11)N,and the average of palm wrench maximum force was(16.00±7.27)N.(3)There was a significant positive correlation between palm preload and palm wrench force(Rs=0.812,P<0.01).There was a significant positive correlation between palm preload and palm wrench maximum force(Rs=0.773,P<0.01).There was a significant positive correlation between palm wrench force and palm wrench maximum force(Rs=0.939,P<0.01).(4)The weight was positively correlated with thumb preload,palm preload,palm wrench force and palm wrench maximum force(P<0.05).(5)These findings confirm that there is a certain biomechanical standard value in the operation of cervical spine fixed-point rotation manipulation to treat cervical spondylosis.There is no significant difference between the left and right manipulations,which indicates that the manipulation has good consistency and repeatability.There is consistency and coordination among palm preload force,palm wrench force,and palm wrench maximum force.Their contributions to the therapeutic effect are similar.Body weight is an important factor affecting cervical spine fixed-point rotation manipulation.

Objective To analyze the current status and influencing factors of occupational stress, job burnout and sleep quality among workers in the secondary industry in Jinshan District, Shanghai City. Methods A total of 1 418 workers from six key industries in Jinshan District, Shanghai City were selected as the study subjects by the stratified cluster sampling method. The Occupational Stress Core Scale, Maslash Burnout Inventory General Survey and Pittsburgh Sleep Quality Index were used to investigate occupational stress, job burnout and sleep quality of the workers. Results The detection rates of occupational stress, job burnout and sleep disturbance among the study subjects were 33.6%, 65.4% and 23.3%, respectively. Multivariate logistic regression analysis showed that the workers with a monthly income <5 000 yuan had a higher risk of occupational stress than those with a monthly income ≥5 000 yuan (P<0.01). The workers with ≥5.0 years of service had a higher risk than those with <1.0 year (P<0.05). Lack of physical exercise, employment in medium- and large-sized enterprises, and shift work were risk factors of occupational stress in the workers (all P<0.01). The workers aged 18-<30 years had a higher risk of job burnout than those aged 45-<60 years (P<0.05). The workers monthly income <5 000 yuan was associated with a higher risk of job burnout than those with ≥9 000 yuan (P<0.05). The workers with 1.0-<10.0 years or ≥15.0 years of service had higher job burnout risks than those with <1.0 year (all P<0.05). Being unmarried, lack of physical exercise, and employment in medium- and large-sized enterprises were risk factor of job burnout in the workers (all P<0.05). The workers with an educational level of high school or above had a higher risk of sleep disturbance than those with junior school or below (P<0.05). The workers who work >56 hours per week had a higher risk than those working ≤40 hours per week (P<0.01). Conclusion There is a high detection rate of occupational stress, job burnout, and sleep disturbance in the secondary industry workers in Jinshan District, Shanghai City. Special attention should be given to workers with low income, lack of physical exercise, employment in medium- and large-sized enterprises, shift work, long service duration, and long weekly working hours to protect their physical and mental health.

OBJECTIVE: To explore the genetic etiology of fetal skeletal dysplasia using whole exome sequencing (WES) and copy number variation sequencing (CNV-seq) techniques, and the feasibility of using WES as the first-tier method for such fetuses. METHODS: Seventy four fetuses with skeletal dysplasia detected by prenatal ultrasound at the Genetic Testing Center of the Women and Children's Hospital Affiliated to Qingdao University from January 2020 to August 2024 were selected as the study subjects. Fetal muscle and peripheral blood samples of the pregnant women and their spouses were collected and subjected to WES analysis. CNV-seq was carried out on all fetal muscle tissue samples. And the results were compared with the CNVs indicated by WES. Genetic etiologies were analyzed across different subtypes of skeletal dysplasia. And the feasibility of using WES as the first-tier genetic test for similar fetuses was assessed, in addition with a systematic cost-effectiveness analysis. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: QFELL-YJ-2024-201). RESULTS: A total of 50 fetuses were diagnosed, which yielded a diagnostic rate of 67.57%. These included 6 chromosomal aneuploidies, 4 chromosomal CNVs and 40 monogenic disorders. The monogenic diseases had involved 46 variant sites in 23 pathogenic genes, among which 12 were unreported previously, including MYH3: c.735T>C, ALPL: c.1324C>T, NEK9: c.1973G>A, MAGEL2: c.2024_2025del, LMBR1: c.423+4914A>C, NEB: c.21273_21276del, COL1A1: c.2651G>C and c.2758G>C, ASPM: c.2473delinsGA, TBX5: c.704G>A, DYNC2H1: c.10893del, and DYNC2I2: c.1270C>T. Substantial concordance was reached between WES-derived CNV calls and CNV-seq findings. No clinically significant CNV was exclusively detected by CNV-seq. Cost-effectiveness modeling demonstrated that implementing WES as the first-tier genetic testing method could reduce the total expenditure when WES unit cost remained below 6.4 folds that of the CNV-seq. CONCLUSION Genetic variants including single nucleotide variations (SNV) of monogenic disorders, chromosomal aneuploidies and genomic CNVs are important causes for fetal skeletal dysplasia. WES is an accurate and efficient method for analyzing the etiology of fetal skeletal dysplasia, particularly in those with a family history of similar phenotype or maternal history of adverse pregnancies.

OBJECTIVE: To explore the detection rate of copy number variations (CNVs) in fetuses with isolated Congenital anomalies of the kidney and urinary tract (CAKUT) and pregnancy outcomes in order to provide a basis for genetic counseling. METHODS: One hundred and eighty eight fetuses who underwent chromosomal microarray analysis (CMA) due to isolated CAKUT detected by prenatal ultrasonography at Qingdao Women and Children's Hospital from January 2021 to December 2024 were selected as the study subjects. According to the ultrasound findings, the fetuses were divided into 8 groups, including renal parenchymal dysplasia group, renal cystic dysplasia group, simple renal parenchymal echo enhancement group, abnormal development of renal collecting system group, duplicated kidney group, ectopic kidney group, horseshoe kidney group, and bladder/posterior urethral abnormalities group. The detection of CNVs was retrospectively analyzed, and the pregnant women were followed up to summarize their pregnancy outcomes. 2 test (or Fisher's exact probability method) was used to compare the CNV detection rates between the groups. This study was approved by the Medical Ethics Committee of the Qingdao Women and Children's Hospital (Ethics No.: QFELL-YJ-2025-85). RESULTS: Among the 188 fetuses with isolated CAKUT, 23 CNVs (12.23%) were detected, of which 13 cases (6.91%) were pathogenic and 10 cases were rated as variants of unknown significance (VOUS). Among the 8 groups, the three groups with the highest proportion were renal cystic dysplasia group, renal metaplasia group, and renal parenchymal dysplasia group. The detection rates of pathogenic CNVs in the three groups were 1.79% (1/56), 6.78% (4/59), and 16.67% (5/30), respectively, with statistically significant differences (P < 0.05). Parental verification was conducted on 12 fetuses detected with the CNVs, confirming that 2 cases were de novo and 10 were inherited from parents with a normal phenotype. After genetic counseling, the parents of 9 fetuses opted to terminate the pregnancy, while 11 chose to continue with the pregnancy, and 3 were lost to follow-up. At the time of last follow-up, the youngest offspring was 5 months old and the oldest was 3 years and 11 months old. One child had renal aplasia, and two were born with hydronephrosis, which have been cured through surgery. The remainders had no obvious abnormality with their growth and development. CONCLUSION CMA testing has important value for prenatal diagnosis of isolated CAKUT. In this study, the detection rate of pathogenic CNVs has increased sequentially in fetuses with renal cystic developmental abnormalities, renal collecting system developmental abnormalities, and renal parenchymal dysplasia, while there was no significant difference in the detection rate of CNVs. For fetuses with isolated CAKUT detected by prenatal ultrasound, CMA testing should be considered, and reasonable pregnancy decisions should be made based on the results of prenatal ultrasound and parental verification.
