Through consulting herbal medicine, medical books, and local chronicles from past dynasties to modern times, this paper systematically researched Spatholobi Caulis from name, origin, producing areas, harvesting, processing, usage, quality evaluation, functions and indications, providing a reference for the development and utilization of famous classical formulas containing Spatholobi Caulis. According to the research, Spatholobi Caulis was first recorded in the Annals of Shunning Prefecture from the Qing dynasty. It was originally a medicinal herb commonly used in Shunning, Yunnan, and was named from the red juice resembling chicken blood that flowed out after the vein was cut off. The mainstream original plants of each dynasty were Kadsura heteroclita and Spatholobus suberectus. Among them, K. heteroclita mainly focused on dispersing blood stasis and unblocking meridians, mainly treating rheumatic pain and injuries caused by falls or blows, and it is mostly used as the raw material of Jixueteng ointments. S. suberectus was commonly used as decoction pieces in decoction, which had the functions of promoting blood circulation and replenishing blood, activating meridians and collaterals, and mainly used for treating anemia, irregular menstruation, and rheumatic bone pain. The production area of Spatholobi Caulis recorded in the Qing dynasty was Yunnan. Currently, the main production area of S. suberectus is Guangxi, while the main production area of K. interior is Yunnan. In the Qing dynasty, the usage of Spatholobi Caulis was an individual prescription with other herbs before making ointments, which was usually composed of the juice of it, safflower, angelica, and glutinous rice. But in modern times, Spatholobi Caulis is mostly sliced and dried for use. The quality of Spatholobi Caulis is often determined by the number of reddish-brown concentric circles on the cut surface, with a higher number indicating better quality. Additionally, the presence of resinous secretions is also considered desirable. Based on the research findings, it is suggested that when developing famous classical formulas containing Spatholobi Caulis, the choice of the primary source should be S. suberectus or K. heteroclita, taking into consideration the therapeutic effects of the formula. It is also recommended that the latest plant classification be referenced in the next edition of Chinese Pharmacopoeia, adjusting the primary source of Kadsurae Caulis to K. heteroclita to avoid confusion caused by inconsistent original names, and the functions adjust to promote Qi circulation and relieve pain, disperse blood stasis and unblock collaterals, treating injuries caused by falls and bruises.

Background As the population ages, there has been a growing focus on the decline in fertility. Research has identified age and fertility history as the primary influencing factors. Nevertheless, there is a deficiency in fundamental data regarding the fertility status among different industries. Objective To investigate the fertility status and influencing factors among female workers aged 22-35 years in different industries. Methods From July 2020 to February 2021, a cross-sectional survey was conducted using a staged sampling approach. This survey specifically targeted 22-35-year-old married female workers with a history of pregnancy in industries such as education, healthcare, finance, and telecommunications, totaling 22903 participants. The survey encompassed industry, demographic characteristics, pregnancy history, time to pregnancy (TTP), and other influencing factors. The influencing factors of decline in fertility were identified by chi-square test and Cox proportional hazards regression. Subsequent industry-specific Cox proportional hazards regression models were used to compared fertility decline patterns across a spectrum of industries after selected influencing factors were adjusted. Results Among the 22903 respondents, 19194 valid questionnaires were collected, with a valid recovery rate of 83.8%. The cumulative pregnancy rates (CRP) of 1-6 months and 1-12 months for the 22-35-year-old female workers were 67.23% and 91.33% respectively. The multivariate analysis showed that region, age, education level, personal annual income, housework time, coping style, gravidity, parity, and spontaneous abortion were influencing factors of fertility decline (P<0.05). Female workers with ≥3 gravidities and ≥2 spontaneous abortions had a higher risk of fertility decline, with hazard ratios (HR) and associated 95% confidence interval (95%CI) of 0.633 (0.582, 0.688) and 0.785 (0.670, 0.921) respectively (P<0.01). Compared to the education industry, the healthcare and finance industries showed a higher risk of fertility decline, with HR (95%CI) values of 0.876 (0.834, 0.920) and 0.909 (0.866, 0.954), respectively (P<0.05). These two HR (95%CI) values remained statistically significant [0.899 (0.852, 0.948) and 0.882 (0.833, 0.934) respectively, P<0.05)] after further adjustment with nine influencing factors such as region and age. Conclusion Regions, age, education level, personal annual income, housework time, coping style, pregnancy and childbirth times, and natural abortion times are influencing factors of fertility decline in female workers. Compared to the education industry, the healthcare and finance industries have a higher risk of declining fertility.

Objective:To test the hypothesis that Pertussis toxin (PTX) can promote the occurrence of interstitial lung disease (ILD) in experimental autoimmune myositis (EAM) model and clarify the potential pathogenic mechanism.Methods:EAM mice model were induced by Skeletal muscle thomogenate with or without PTX, and the relationship between ILD phenotypes and neutrophil extracellular traps (NETs) infiltration was analyzed by histopathological and serological studies in EAM with PTX group and EAM without PTX group. Healthy mice were given PTX alone intraperitoneally to clarify whether NETs formation could be induced in vivo, and neutrophils separated from healthy human blood were intervened with PTX to induce NETs formation in vitro. The data was tested for normality using Shapiro-Wilk. Statistical methods and were analyzed using t-test or ANOVA, and multiple comparisons between different groups were tested using Tukey test. Results:Compared with EAM without PTX group, lung tissues in EAM with PTX group had multiple pathological changes similar to polymyositis/dermatomyositis-related ILD. Nonspecific interstitial pneumonia and usual interstitial pneumonia were the main pathological types. The pulmonary interstitial lesions were accompanied by significant infiltration of NETs; and serum NETs markers levels were obviously elevated in EAM with PTX group, compared with the control group [ n=5, (87±10) ng/ml], cfDNA levels were statistically significantly elevated in both the EAM without PTX group [ n=4, (115±27) ng/ml] and the EAM with PTX group [ n=7, (150±50) ng/ml] ( F=4.24, P=0.038); Cit-H3-DNA levels were elevated in the EAM without PTX group ( n=4, 0.24±0.09), and in the EAM EAM with PTX group ( n=6, 0.33±0.11) compared with the control group ( n=4, 0.13±0.02) ( F=6.21, P=0.016). After PTX intervention, serum cfDNA levels were higher in the PTX group [ n=3, (100±40) ng/ml] than in the control group [ n=3, (45±12) ng/ml, t=2.27, P=0.086]; PTX also induced neutrophils to form NETs in vitro. Conclusion:PTX may promote the development of ILD in EAM mice model by inducing the formation of NETs, indicating that EAM mice can serve as a model for targeting NETs to study the pathogenesis ILD.

Objective:To investigate the effects of external application of Sanying Plaster on the size of thyroid nodules and the states of depression and anxiety in patients with benign thyroid nodules.Methods:A randomized controlled trial was conducted. A total of 120 patients with benign thyroid nodules from the outpatient clinic of the Department of Thyroid Diseases at Shanghai Traditional Chinese Medicine Hospital from June to December 2022 were selected as the subjects of the study. They were divided into two groups using the random number table method, with 60 patients in each group. The control group received lifestyle intervention treatment, while the treatment group received Sanying Ointment in addition to the treatment of the control group. Both groups were treated for 3 months. TCM syndrome scores were measured before and after treatment; the maximum diameter of thyroid nodules was measured using a color Doppler ultrasound transverse section; the quality of life was assessed using the short form 36 (SF-36); the degree of anxiety and depression was evaluated using the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS); adverse reactions during the treatment period were recorded, and the clinical efficacy was evaluated.Results:During the treatment period, 4 cases in the treatment group and 3 cases in the control group did not complete the treatment. Finally, 56 cases in the treatment group and 57 cases in the control group entered the efficacy evaluation. The total effective rate of the treatment group was 71.4% (40/56), and that of the control group was 14.0% (8/57), with a statistically significant difference between the two groups ( χ2=26.82, P<0.001). After treatment, the TCM syndrome score of the treatment group (10.02±3.65 vs. 16.65±3.44, t=-10.24) was lower than that of the control group ( P<0.001); the maximum diameter of thyroid nodules [11.00 (4.65, 19.93) mm vs. 15.00 (7.15, 28.50) mm, Z=-2.43] was lower than that of the control group ( P<0.05); the SF-36 score [121.83 (117.00, 130.00) vs. 114.42 (104.25, 127.50), Z=-2.62] was higher than that of the control group ( P<0.01); the SDS (46.72±4.59 vs. 57.02±5.99, t=14.80) and SAS (42.25±5.72 vs. 50.60±7.12, t=10.04) scores were lower than those in the control group ( P<0.001). The incidence of adverse reactions during the treatment period in the treatment group was 3.5% (2/57), and no adverse reactions occurred in the control group. Conclusion:The external application of Sanying Ointment helps to reduce the size of thyroid nodules in patients with benign thyroid nodules, improve the quality of life and anxiety and depression, and increase clinical efficacy with good safety.

By reviewing ancient materia medica, medical books and modern literature, the name, origin, quality evaluation, producing area and processing methods of Huoxiang herbs were systematically investigated and researched, so as to provide reference and basis for the development and utilization of famous classical formulas containing Huoxiang herbs. Through the herbal textual research, it can be seen that most of materia medica in past dynasties have taken Huoxiang as the nominal rectification, and the mainstream base used is Pogostemon cablin. In order to distinguish another plant of the same family, Agastache rugosa, which has been widely used in Chinese folk since the Ming dynasty, and respect geo-authentic region, Pogostemonis Herba is also named Guanghuoxiang. Pogostemonis Herba is native to Vietnam and other Southeast Asian countries, and was introduced to China as a spice through Guangdong and other places in the early days, and has been successfully cultivated in the south of China since the Song dynasty. The medicinal parts are mostly dried aboveground parts, and the leaves and stems are also separated for medicine sometimes. The geo-authentic region of Pogostemonis Herba is Guangdong in the past dynasties, and it is currently cultivated in Guangzhou, Zhaoqing, Zhanjiang of Guangdong province and Hainan province, with the most famous one cultivated in Shipai. Pogostemonis Herba is mainly planted by cutting propagation. It usually sprouts in February and is harvested in June. The main processed method in region is stuffy dry, which is placed in the sun and repeatedly suffocated until it has an aromatic smell and the color turns yellow. The processing method is mostly to use the raw product as medicine after being selected. Based on the research results, it is suggested that the leaves of P. cablin are used in Yangweitang, for Huopo Xialingtang, it is recommended to choose the raw product of A. rugosa that is removed the roots and old stems.

OBJECTIVE To study main way and target of Euphorbia kansui after stir-frying with vinegar. METHODS Twenty-four SPF grade SD rats were randomly divided into blank group, E. kansui group (850 mg/kg) and vinegar stir-fried E. kansui group (850 mg/kg), with 8 rats in each group. Blank group was given 0.5% sodium carboxymethyl cellulose solution intragastrically, and E. kansui group and vinegar stir-fried E. kansui group were given relevant test sample for consecutive 20 d. The rats’ urine of 12 hours was collected on the 20th day. The urine samples of rats in each group were determined by UPLC-Q- Exactive-MS. The data was pre-processed by Compound Discoverer 3.0 software, and the metabolite structure was identified by BioCyc, HMDB and other databases. Whether different groups presented their own clustering phenomenon was observed by principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA), etc. Based on the pathway analysis of MetaboAnalyst, the potential targets of detoxification mechanism of E. kansui after stir-frying with vinegar were predicted. RESULTS Twenty significantly differential endogenous metabolites were identified, of which 10 target metabolites, such as N-acetyl-L-aspartate and 3-phosphonooxypyruvic acid, were targets of detoxification mechanism of E. kansui after stir- frying with vinegar. The main metabolic pathways included arginine biosynthesis, alanine, aspartic acid and glutamic acid metabolism, cysteine and methionine metabolism, and arginine and D-ornithine metabolism. The biological significance of all related metabolites in the pathways was analyzed and speculated; after stir-frying with vinegar, E. kansui may alleviate neurotoxicity by reducing the level of N-acetyl-L-aspartic acid; E. kansui had a protective effect on cardio-cerebrovascular system by increasing the level of L-high arginine. CONCLUSIONS After stir-frying with vinegar, E. kansui can significantly improve the adverse factors in terms of nervous system, cardio-cerebrovascular system, immune system and energy metabolism. The most concentrated metabolic pathway related to its detoxification mechanism is arginine biosynthesis.

OBJECTIVE To screen the active ingredient with estrogenic effect from total flavonoids of Cuscutae Semen. METHODS The estrogenic effect of total flavonoids from 10 batches of Cuscutae Semen was evaluated with mouse uterus coefficient and endometrial thickness as evaluation indexes, establish its fingerprint and calibrate the common peak. Common peak and spectrum-effect relationship of the above two indicators were analyzed by bivariate relationship analysis and grey correlation analysis to screen active components with estrogenic effect. UPLC-Q-TOF-MS technology was used to characterize the active components. RESULTS The estrogenic effect of total flavonoids from 10 batches of Cuscutae Semen was good. Twenty-eight and thirty-three common peaks of total flavonoids in Cuscutae Semen were obtained in the positive and negative ion modes respectively. The constituents represented by peaks 7,10,12-16,26 in positive ion mode and peaks 2,5,8,9,12,16,19,22-26 in negative ion mode were highly correlated with the estrogenic effect of total flavonoids from Cuscutae Semen. Further identification showed that the active substances with estrogenic effect from the total flavonoids of Cuscutae Semen were 5,7,3′, 4′-tetramethoxyflavone, 6- O-(trans) p-coumarin-furanfructose-(2→1)-glucopyranoside, rutin, kaempferol-3,7-diglucoside, apigenin-7-O-glucoside, hyperoside, baicalin, quercitin, quercetin, apigenin, kaempferol, isorhamnetin, rhododendron, isoquercetin, kaempferol-3-furan arabinoside, 2,6-octadecanediacetylic acid. CONCLUSIONS A total of 16 chemical components with estrogenic effect are screened from total flavonoids of Cuscutae Semen in the study, which can provide reference for the development of phytoestrogens.

ObjectiveTo analyze the disease burden in Sichuan Province in 2010 and 2020, and to provide reference for disease prevention and control. MethodsMonitoring data on causes of death in Sichuan Province in 2010 and 2020 were collected. Disability-adjusted life years (DALY), years of life lost (YLL) and years lived with disability (YLD) were calculated to assess the disease burden in Sichuan Province. ResultsIn 2020, DALY was 7.004 0 million years, among which YLL and YLD were 3.719 6 million and 3.284 4 million, respectively. Compared with 2010, the total DALY in 2020 increased by 8.27%, most of which came from the increase of YLL (16.66%). In 2020, the standardized total DALY rate was 69.91‰, which decreased by 9.87% compared with 2010. Specifically, the rate decreased by 15.87% for females and 5.28% for males. In 2020, the burden of DALY disease in the elderly over 60 years old increased by 34.55% compared with 2010. The burden of infectious and maternal diseases decreased the most, and the standardized DALY rates of male and female in 2020 decreased by 47.03% and 55.50% compared with 2010, respectively. Injury was the next most important factor, which decreased by 32.97% in males and 26.92% in females. The standardized DALY rate of chronic diseases increased by 5.41% in males and decreased by 10.67% in females. In 2020, compared with 2010, the standardized DALY rate of males increased significantly in diabetes (82.02%), nervous system and mental disorders (26.31%), and cardiovascular and cerebrovascular diseases (19.86%). Among women, significant increases were seen in diabetes mellitus (54.74%), neurological and mental disorders (35.52%), and musculoskeletal and connective tissue diseases (23.51%). ConclusionThe overall disease burden in Sichuan Province shows a declining trend, mainly attributed to the decrease in infectious and maternal diseases and injuries. The disease burden among people over 60 years old has increased significantly, with the focus on chronic diseases such as diabetes, cardiovascular and cerebrovascular diseases, nervous system and mental disorders, and musculoskeletal and connective tissue diseases.
