ObjectiveTo compare the differences between wild Alpiniae Oxyphyllae Fructus(WAOF) and cultivated Alpiniae Oxyphyllae Fructus(CAOF) through a traditional quality evaluation system for medicinal materials. MethodsA total of 10 batches of WAOF and 12 batches of CAOF samples were collected from various regions of Hainan province. Relevant analytical methods from the 2020 edition of the Pharmacopoeia of the People's Republic of China were employed to observe the characteristics of WAOF and CAOF, followed by microscopic identification, thin-layer chromatography(TLC) identification, moisture content(toluene method), total ash, acid-insoluble ash, water-soluble and alcohol-soluble extracts(hot dipping method), water-soluble protein, total polysaccharides and total flavonoids(ultraviolet spectrophotometry), and volatile oil content(method A under general rule 2204). The contents of five active components(protocatechuic acid, chrysin, kaempferol, tectochrysin and nootkatone) were quantified using ultra-performance liquid chromatography(UPLC), and the antioxidant activity was evaluated. Building upon traditional quality evaluation of AOF, quantitative measurements were conducted on its appearance traits including diameter, length, plumpness(diameter/length ratio), and color. Canonical correlation analysis was performed using SPSS 26.0 to explore relationships between appearance traits and intrinsic quality. ResultsNo significant differences were observed between WAOF and CAOF in microscopic observation, TLC identification, moisture content, protocatechuic acid content, kaempferol content, odor, or antioxidant activity measured by 2,2ʹ-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS) method. WAOF exhibited significantly higher levels in water-soluble extracts, alcohol-soluble extracts, total polysaccharide content, water-soluble protein content, 100-grain weight, length, and total color difference(ΔE*ab) compared to CAOF(P<0.01). In contrast, CAOF showed significantly higher levels of total ash, acid-insoluble ash, content of total flavonoids, volatile oil content, chrysin content, tectochrysin content, nootkatone content, diameter, plumpness, lightness(L*), red-green chromaticity(a*), yellow-blue chromaticity(b*), and antioxidant activity measured by 1,1-diphenyl-2-picrylhydrazyl(DPPH) method compared to WAOF(P<0.01). Correlation analysis between 7 phenotypic traits and 8 quality traits revealed that among the phenotypic traits, plumpness, L*, a*, and b* exerted significant influence on intrinsic quality. Among the quality traits, total flavonoids, volatile oils, nootkatone, chrysin, and tectochrysin contributed substantially to intrinsic quality. ConclusionPlumpness, L*, a*, and b* of AOF significantly influence its intrinsic quality, and higher values of these parameters indicate relatively superior intrinsic quality. The comprehensive quality evaluation reveals that CAOF samples collected in this study are superior to their wild counterparts.

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.

Objective To explore the potential value of serum lipoxin A4 (LXA4) in monitoring bacterial load and anti-tuberculosis treatment progression in patients with pulmonary tuberculosis (PTB). Methods From January 2021 to January 2022, forty patients with active PTB, who were admitted to Shaanxi Provincial Tuberculosis Prevention and Control Hospital, were selected as the active PTB group, 38 patients with latent tuberculosis infection (LTBI) were selected as the LTBI group, and 28 healthy volunteers who underwent physical examination in our hospital during the same period were included as the healthy control group. The active PTB patients received a 2-month standard anti-tuberculosis chemotherapy, while the other two groups were untreated. Fasting venous blood was drawn from the three groups at enrollment (baseline), after 2 months of treatment, and upon the completion of 6 months of treatment in the active PTB group to measure serum LXA4 levels using enzyme-linked immunosorbent assay (ELISA). The relationship between serum LXA4 level and clinical manifestations, bacterial load, chest imaging manifestations, and treatment progress was analyzed. Results At baseline, serum LXA4 levels in the active PTB group, LTBI group, and healthy control group were [397.72 (210.68, 573.00)], [178.18 (108.17, 271.87)], and [131.06 (76.24, 166.04)] pg/mL, respectively. The levels in the active PTB and LTBI groups were significantly higher than those in the healthy control group, with statistical significance (P<0.01). According to the grading of acid-fast bacilli (AFB) sputum smears at diagnosis, baseline serum LXA4 level increased in the active PTB group with AFB sputum smear grade (P<0.001), and there was a positive correlation between serum LXA4 level and sputum smear grade (rs=0.209, P=0.003). After 6 months of treatment, the serum LXA4 level in the active PTB group was lower than the baseline value (P=0.002). The serum LXA4 level can predict treatment progress, with a baseline sensitivity of 55.0% (22/40), and after 6 months of treatment, 8 patients (20.0%) still showed positive serum LXA4 levels. Conclusions Serum LXA4 may be a useful biomarker for monitoring the progression of PTB treatment.

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.

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.

By reviewing ancient materia medica, medical books, prescription books and modern literature, this paper conducted a systematic research on name, origin, medicinal parts, producing area, quality, harvesting and processing methods, functions and toxicity of Polygoni Multiflori Radix(PMR) and Polygoni Multiflori Caulis(PMC) in famous classical formulas. It was found that the name of Heshouwu was first found in the Biography of Heshouwu and originated from its discoverer, and then still in use today. Since the Song dynasty, Heshouwu has been included in the materia medica with Fallopia multiflora as the mainstream origin. Since the Ming dynasty, in addition to F. multiflora, Cynanchum bungei, C. wilfordii, C. auriculatum have been used as the origin of Heshouwu. Heshouwu is widely distributed, the production areas recorded in ancient times are mainly Luchuan, Guangxi and Ganzhou, Jiangxi, and in modern times, Deqing, Guangdong and other places are respected as the geo-authentic habitats. Its origin processing is mostly dug out, washed, sliced and dried in the sun. Modern literature concludes that the quality of PMR is better in terms of weight, solid quality and powder, while PMC is better in terms of uniformity and purplish-red skin. In the Qing dynasty and before that, it was recorded in the materia medica that PMR was harvested mainly in late spring, mid-summer and early autumn, in modern times, it was harvested mainly in spring and autumn, while PMC was harvested in autumn. In Song dynasty, the processing method of PMR was mainly soaked with rice-washed water, the Ming dynasty for black bean steaming method, the Qing dynasty for steaming followed by black bean juice maceration, while in modern times, it is mostly sliced and steamed with black bean juice and yellow rice wine until the juice is absorbed. PMC is prepared by removing impurities, washing or moistening, and cutting into sections to dry. During the five dynasties, PMR was used to treat infertility as well as gastrointestinal diseases and blood in the stool caused by wind chill, and during the Song dynasty, it was mostly used raw products for the treatment of scrofula and carbuncles, and in the Yuan and Ming dynasties, raw and processed products were used, and Polygoni Multiflori Radix Praeparata was used to treat hemorrhoids, waist and knee soreness. PMC is mainly used for treating insomnia, fatigue and sweating, wind sores and scabies, etc. In the Song dynasty, the ancients considered that PMR was non-toxic, but its toxicity was gradually discovered after the Ming dynasty, and the toxicity mechanism has not been clearly analyzed yet. Based on the results of the textual research, it is recommended that F. multiflora be used as the base for development of famous classical formulas containing PMR, and from the safety perspective, it is recommended to use raw products with caution, oral administration must be used processed products. PMC is recommended to use raw products.

Objective:To analyze the changes in self-efficacy and its influencing factors in type 2 diabetic patients after community-based self-management group intervention.Methods:From August to November 2014, a 3-month community-based self-management intervention study of type 2 diabetes patients was implemented in Fangshan District, Beijing. 510 patients were recruited through posters, household inquiries and telephone notification and then were randomly divided into intervention group (260 patients) and control group (250 patients). Finally, 500 patients completed the study, including 259 in the intervention group and 241 in the control group. Self-efficacy score was measured through face-to-face interview at different time points, including pre-intervention, post-intervention, 2 years after the intervention and 5 years after the intervention, respectively. A two-level random coefficient model was fitted to analyze the long-term trend of self-efficacy and its relationship with group intervention.Results:Individual-level educational attainment, disease duration as well as their treatment plans had a positive correlation with self-efficacy of type 2 diabetic patients while gender and age did not affect their self-efficacy. Patients with junior middle school education, senior high school education and university and above education had 4.66 ( P<0.05), 6.40 ( P<0.05) and 11.02 ( P<0.05) points higher than those with primary education, respectively. The self-efficacy of diabetic patients increased by 0.23 ( P<0.05) for each additional course year. The effect of treatment plan on self-efficacy was mainly reflected in the self-efficacy of taking medication or insulin injection as prescribed and blood glucose monitoring. After controlling for the confounding factors, i.e., gender, age, disease duration, educational attainment, and treatment plan, self-efficacy scores at the post-intervention increased in both groups compared to those at the pre-intervention. The intervention group had 7.95 points higher than the control group ( P<0.05). After the intervention, the self-efficacy scores of both groups decreased year by year while the intervention group declined faster, with 5.41 points ( P<0.05) at 2 years after the intervention and 8.94 points ( P<0.05) at 5 years after the intervention. Conclusion:Community-based self-management group intervention could improve the self-efficacy of type 2 diabetic patients while the self-efficacy decreases year by year in the absence of follow-up intervention.
