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 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 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.

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 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 investigate the regulatory effects of microRNA-23b-3p (miR-23b-3p) on the autophagy and apoptosis of human lens epithelial cells induced by high glucose.Methods:Thirty diabetic cataract (DC) patients as DC group and 30 patients with simple cataract as simple cataract group were enrolled in The First Affiliated Hospital of Xi'an Medical University from September 2019 to October 2020.Conventional phacoemulsification and intraocular lens transplantation were performed in both groups.The anterior capsular tissue was collected during the operation.The expression of miR-23b-3p in the anterior lens capsule was detected by real-time fluorescence quantitative PCR (RT-qPCR). Human lens epithelial cell line HLEB3 cells were cultured in vitro and divided into normal control group and high-glucose group, which were cultured in normal and high-glucose medium, respectively.The targeting relationship between proto-cadherin 17 (PCDH17) and miR-23b-3p was predicted according to the bioinformatics database, and was verified by the dual-luciferase reporter gene experiment.High glucose-cultured HLEB3 cells were divided into miR-23b-3p mimics group, negative control (NC) mimics group, NC-siRNA group, PCDH17-siRNA group, miR-23b-3p mimics+ Vector group, miR-23b-3p mimics+ pcDNA-PCDH17 group, and were transfected with corresponding reagents according to grouping.The expression of miR-23b-3p and PCDH17 mRNA was detected by RT-qPCR.The expressions of a mammalian homolog of yeast Atg6/Vps30 (Beclin-1), microtubule-associated protein 1 light chain 3 (LC3B), c-Jun N-terminal kinases (JNK), phosphorylated (p-) JNK, c-Jun, p-c-Jun, B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated X protein (Bax) proteins were assayed by Western blot.The apoptosis rate was detected by flow cytometry.The study protocol was approved by the Ethics Committee of The First Affiliated Hospital of Xi'an Medical College (No.LSL2019037). Written informed consent was obtained from each patient. Results:The relative expression of miR-23b-3p in the anterior lens capsule of DC group was 0.35±0.15, which was significantly lower than 1.00±0.09 of simple cataract group ( t=44.627, P<0.01). There were significant differences in the relative expression levels of miR-23b-3p, LC3B Ⅱ/Ⅰ, Beclin-1, Bcl-2 and Bax proteins among normal control group, high glucose group, high glucose+ NC mimics group and high glucose+ miR-23b-3p mimics group ( F=21.325, 28.318, 17.634, 15.482, 22.325, 26.537; all at P<0.01). Compared with normal control group, the apoptosis rate, LC3B Ⅱ/Ⅰ, Beclin-1 and Bax protein expressions in high glucose group were significantly increased, and the Bcl-2 protein expression was significantly decreased (all at P<0.05). Compared with NC mimics group, the apoptosis rate, LC3B Ⅱ/Ⅰ, Beclin-1, and Bax protein expressions were significantly decreased and the Bcl-2 protein expression was significantly increased in miR-23b-3p mimics group (all at P<0.05). The results of bioinformatics and dual-luciferase reporter gene experiments showed that PCDH17 was a target gene of miR-23b-3p, and the relative expression of PCDH17 mRNA in miR-23b-3p mimics group was significantly lower than that in NC mimics group ( P<0.05). Compared with NC-siRNA group, the apoptosis rate, LC3B Ⅱ/Ⅰ, Beclin-1 and Bax protein expressions in PCDH17-siRNA group were significantly decreased, and the Bcl-2 protein expression was significantly increased ( t=9.116, 12.413, 5.349, 3.273, 8.419; all at P<0.01). There were significant differences in the relative expression levels of p-JNK/JNK, p-c-Jun/c-Jun, LC3B Ⅱ/Ⅰ, Beclin-1, Bcl-2 and Bax proteins in NC mimics group, miR-23b-3p mimics group, miR-23b-3p mimics+ Vector group and miR-23b-3p mimics+ pcDNA-PCDH17 group ( F=24.724, 19.319, 23.418, 17.562, 20.263, 15.249; all at P<0.05). Compared with the miR-23b-3p mimics+ Vector group, the expressions of p-JNK/JNK, p-c-Jun/c-Jun, LC3B Ⅱ/Ⅰ, Beclin-1 and Bax were significantly increased, and the expression of Bcl-2 protein was decreased in miR-23b-3p mimics+ pcDNA-PCDH17 group (all at P<0.05). Conclusions:MiR-23b-3p have a protective effect on HLEB3 cells in a high-glucose environment, mainly by targeting PCDH17 to regulate the JNK signaling pathway to inhibit high glucose-induced autophagy and apoptosis.

Objective:To investigate the status of satisfaction of postgraduates majoring in public health with the teaching material of The prevention and control of chronic non- communicable disease, so as to provide the basis for promoting the teaching and optimizing the reprint of the teaching material. Methods:An online survey was conducted among 180 public health postgraduates of Batch 2018 to Batch 2020 from China CDC who took the selective course of "prevention and control of chronic non-communicable diseases". The survey content included the overall satisfaction of the respondents with the teaching material and such four levels of satisfaction as primary indicators at the content level, thinking level, motivation level and arrangement level and 20 secondary indicators. The statistical analysis was made by SPSS 25.0.Results:The effective response rate was 90.56% (163/180), and the overall satisfaction of postgraduates with the teaching material was 88.96%. The satisfaction of "scientificity", "comprehensiveness", "internal coordination" and "hierarchy" at the content level, "systematic thinking" and "quality education" at the thinking level, "deepening the understanding and application of relevant knowledge in the field of chronic disease prevention and control" and "the content is convenient for self-study and helps guide the construction of new knowledge" at the motivation level, and "accurate words, fluent language and easy to read and understand" and "firm binding, good paper quality and clear printing" at the arrangement level of the teaching material was more than 90.00%. Only the satisfaction of "the critical thinking" at the thinking level and "stimulating learning enthusiasm" at the motivation level was less than 85.00%.Conclusion:The teaching material of The prevention and control of chronic non- communicable disease meets the learning needs of postgraduates majoring in public health, and students have high overall satisfaction evaluation on the teaching material. It is necessary to further optimize the two aspects of "the critical thinking" and "stimulating learning enthusiasm" in the revision of the teaching material.

Objective:To predicate whether China can achieve the United Nations Sustainable Development Goals (SDGs) 3.4.1 to reduce the age-standardized mortality rate of four major non-communicable diseases (NCDs) in residents aged 30-70 years by 2030 based on the trend of the mortality from 1990 to 2019.Methods:We collected the mortality data on cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes by age, gender and year in China from the Global Disease Burden Study 2019 (GBD2019). The age-period-cohort (APC) Bayesian model was applied for modeling the age-standardized mortality rate of four major NCDs in China during 2020-2030 according to the trend of the mortality during 1990-2019, and comparing the predicted value in 2030 with the observed value in 2015 to evaluate the possibility of achieving SDGs 3.4.1.Results:The age-standardized mortality rate of the four major NCDs in China showed a downward trend during 1990-2019. It is predicted that the number of death of the four NCDs in Chinese residents aged 30-70 years would increase from 2.96 million in 2020 to 3.19 million in 2030, while the age-standardized mortality rate would decrease from 308.49/100 000 in 2020 to 277.80/100 000 in 2030. The age-standardized mortality rate in 2030 would only decrease by 15.94% (18.73% for males and 14.31% for females) compared with 330.46/100 000 in 2015, with a 25.09% decrease for cardiovascular diseases, 4.76% for cancers, 37.21% for chronic respiratory diseases, and unchanged for diabetes.Conclusion:Although the age-standardized mortality rate of four major NCDs declined from 1990 to 2019 in China, it is difficult to achieve the SDGs of a 1/3 mortality rate reduction by 2030 according to the current declining trend, suggesting more active and effective efforts for NCD prevention and control are needed.

Barium carbonate poisoning is mostly caused by mistaken ingestion in clinical cases, and self-administration of poisoning is rare. In November 2020, Tianjin Occupational Disease Prevention Hospital admitted a patient with severe hypokalemia complicated with arrhythmia after taking poison. It is very important to take timely and effective potassium supplementation, symptomatic and detoxification treatment in the course of treatment. At the same time, closely observing the changes of vital signs and taking quick and accurate rescue measures in the event of malignant arrhythmia are the keys to ensuring the success of rescue. In this paper, the clinical data of the case were retrospectively analyzed, providing reference for the diagnosis and treatment of similar clinical cases.
