OBJECTIVE: To investigate the effect and mechanism of Shuangshi Tonglin Capsules (SSTL) in the treatment of prostate fibrosis (PF). METHODS: Human prostate stromal cells (WPMY-1) were used for in vitro experiments to establish PF cell models induced with estradiol (E₂). The cell proliferation, migration and clonogenic capacity were determined by cell counting kit-8, scratch assay, and crystal violet staining, respectively. Sprague-Dawley rats were used for in vivo experiments. The changes in histomorphology and organ index of rat prostate by SSTL were determined. Pathologic changes and collagen deposition changes in rat prostate were observed by haematoxylin and eosin (HE) and Masson staining. Enzyme-linked immunosorbent assay kits were used to determine changes in rat PF markers fibroblast growth factor-23 (FGF-23), E₂ and prostate specific antigen (PSA). Mechanistically, changes in oxidative stress indicators by SSTL were determined in WPMY-1 cells and PF rats. Then the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) and transforming growth factor-β1 (TGF-β1)/Smad pathway-related proteins as well as Nrf2 and TGF-β1 mRNA were further detected by Western blot or quantitative real-time polymerase chain reaction both in vivo and in vitro. RESULTS: In the efficacy study, SSTL significantly reduced the proliferation, migration, and clonogenic ability of cells, improved the morphology of the glandular tissue, significantly reduced the prostate index, reduced glandular fibrous tissue and collagen deposition, and resulted in a significant decrease in the levels of FGF-23, E₂ and PSA (P<0.01 or P<0.05). In the mechanistic study, SSTL ameliorated oxidative stress by significantly increasing superoxide dismutase and glutathione peroxidase levels and decreasing malondialdehyde level in WPMY-1 cells and rats (P<0.01 or P<0.05). SSTL significantly elevated the expressions of Nrf2, HO-1, NAD(P)H quinone oxidoreductase 1 (NQO-1), and Smad7 proteins in both cells and rats, and significantly decreased the expressions of TGF-β1, collagen I, α-smooth muscle actin and Smad4 proteins (P<0.01 or P<0.05). SSTL also elevated the content of Nrf2 mRNA and decreased the content of TGF-β1 mRNA in cells and rats (P<0.01 or P<0.05). The Nrf2 inhibitor ML385 was added in in vitro experiments to further validate the pathway relevance. CONCLUSION SSTL was effective in improving PF in vivo and in vitro, and its mechanism of action may function through the Nrf2/TGF-β1 signaling pathway.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

The core of theory of visceral manifestation of spleen is about'spleen in charge of transportation and transformation,spleen qi dispersing the essence'.Middle-jiao spleen-earth has the functions of digesting food and transporting food essence,and maintaining the homeostasis of glucose and lipid metabolism in the body.'Spleen in charge of transportation and transformation,spleen qi dispersing the essence'functions like the glucose and lipid metabolism at physiological state.The deficiency of spleen results in the dysfunction of food in-take and digestion and the susceptibility to external pathogens;qi deficiency and blood stasis lead to the interior damp-heat,and the long-term accumulation of damp-heat develops into stasis and then turns into toxins,which eventually induces inflammation-to-tumor transition.The pathogenesis of'spleen deficiency being the root cause and stasis blended with toxins'is correlated with the pathological changes of inflammation-to-tumor transition.The therapy of strengthening the spleen,dispersing essence and removing turbidity is effective on improving the disorder of glucose and lipid metabolism,and the therapy of strengthening the spleen,resolving stasis and removing toxin is effective on restraining the process of inflammation-to-tumor transition in the stomach.It has become a new direction in the field of spleen-stomach research to expound the scientific connotation of the essence of spleen function of'spleen in charge of transportation and transformation,spleen qi dispersing the essence'from the perspective of glucose and lipid metabolism,to focus on the inflammation-to-tumor transition process of major diseases of digestive system,to explore the evolution of the traditional Chinese medicine syndromes of inflammatory diseases and precancerous lesions of the digestive tract,and to reveal the pharmacological mechanism of treatment from the perspective of spleen,which will enrich the scientific connotation of theory of visceral manifestation of spleen and promote the modernization and internationalization of traditional Chinese medicine.

Objective To study the effects of dual-hemispheric transcranial direct current stimulation(Dual-tDCS)on upper limb motor function in chronic-phase stroke patients to provide theoretical references for neural mechanisms-based treatment of upper limb dysfunction.Methods Totally 24 chronic-phase stroke patients with upper limb motor dysfunction were selected from some hospital and divided into an experimental group(n=13)and a control group(n=11)the random number table.The control group was treated with tDCS pseudo-stimulation combined with conventional rehabilitation,while the experimental group was given with Dual-tDCS combined with conventional rehabilitation.The patient activities were assessed before and after treatment with Fugl-Meyer assessment upper limb scale(FMA-UL)and activities of daily living(ADL)scale.The changes of primary motor cortex(M1 area)and whole brain functional connectivity(FC)were compared before and after treatment.SPSS 24.0 statistical software was used for data analysis.Results After treatment,the two groups both had the FAM-UL and ADL scores increased significantly,and the experimental group had the scores statistically higher than those of the control group,and the differences were all statistically significant(P＜0.05).In the control group,the analysis on M1 area and whole brain FC after treatment indicated the FC decreased from M1 area at the unaffected side to midoccipital gyrus at the affected side and lingual gyrus and healthy angular gyrus at the unaffected side;there were no brain areas with changed FC found(P＜0.01).In the experimental group,the FC was lowered from M1 area at the unaffected side to cerebellum and cerebellar vermis at the unaffected side,while raised to precentral gyrus at the affected side(P＜0.01);the FC ascended from M1 area at the affected side to cerebellum and middle temporal gyrus at the affected side,while declined to precentral gyrus at the unaffected side(P＜0.01).Conclusion The neuromodulatory effect of Dual-tDCS on the brain improves FC in motor and non-motor-related brain areas in chronic-phase stroke patients,and may contribute to rehabilitation of upper limb motor dysfunction in chronic-phase stroke.[Chinese Medical Equipment Journal,2024,45(2):67-73]

OBJECTIVES: To develop the birth weight curve of singleton neonates with a gestational age of 24-42 weeks, and to investigate the regional differences of the birth weight curve. METHODS: A total of 11 maternal and child health hospitals with more than 7 000 neonates delivered annually were selected in 11 cities of China (Haikou, Guangzhou, Shenzhen, Liuzhou, Guilin, Quanzhou, Chongqing, Chengdu, Changsha, Ningbo, and Lianyungang), and all live singleton neonates delivered in the 11 hospitals from January 1, 2017 to December 31, 2020 were enrolled for the development of birth weight curves. RESULTS: A total of 93 720 singleton neonates with a gestational age of 24-42 weeks from the 11 cities were included in the study. The reference values of the 3rd-97th percentiles of birth weight of singleton neonates for the total of the 11 cities and for each of the 11 cities were established, and the birth weight percentile curves were drawn. The birth weight curve level of singleton neonates in Shenzhen and Quanzhou was almost the same as the average level of the 11 cities; the birth weight curve level of singleton neonates in Haikou, Guangzhou, Guilin, and Liuzhou was slightly lower than the average level of the 11 cities; the birth weight curve level of singleton neonates in Chongqing, Chengdu, and Changsha was slightly higher than the average level of the 11 cities; the birth weight curve level of singleton neonates in Ningbo and Lianyungang was higher than the average level of the 11 cities. The average birth weight curve level of singleton neonates in the 11 cities were very close to that of China Neonatal Cooperation Network in 2011-2014. CONCLUSIONS The reference values of the 3rd-97th percentiles of birth weight of singleton neonates for the total of the 11 cities and for each of the 11 cities are developed, which can be used as a reference for evaluating the intrauterine growth of singleton neonates in the region. The level of intrauterine growth of neonates in some cities is different from the national level.

Abstract: Mycobacterium senegalense is one of the major pathogens causing bovine farcy, and reports of its infection in human are rare. Here is a report on a woman who had been taking hormones and immunosuppressants for a long time for SLE and underwent abdominal soft tissue infection with Mycobacterium senegalense after abdominal liposuction, to provide reference for clinical diagnosis and treatment. The patient, female, 32 years old, has a history of SLE for more than 2 years, and currently takes "methylprednisolone, hydroxychloroquine, and mycophenolate mofetil" regularly. Nine months before the patient was admitted to the hospital, she once performed abdominal, waist and buttock liposuction in a medical beauty institution. One month after the operation, several masses gradually appeared on the abdominal wall, accompanied by tenderness, one of the masses had obvious fluctuation on palpation and purulent fluid could be drawn out. The location of the abdominal wall mass was consistent with the insertion site of the liposuction needle. After the onset of the disease, the patient went to the medical beauty institution for puncture of the abdominal wall mass, and 5 mL of purulent fluid was pierced and sent for bacterial culture, and cultured "Mycobacterium Senegalense", after 3 days of treatment with "cephalosporin" antibiotics (specifically unknown), the symptoms did not improve, so she went to the second affiliated hospital of hainan medical college. After completing the relevant examinations during the hospitalization in our hospital, in order to clarify the etiology, another abdominal puncture to extract pus was performed, the mycobacterial culture + identification results: Mycobacterium senegalense. Consistent with the out-of-hospital results, the diagnosis of Mycobacterium senegalense infection was confirmed. After 3 months of treatment with "cefoxitin, azithromycin, amikacin, and levofloxacin", the patient's abdominal wall soft tissue infection was cured. Trauma or invasive procedures can lead to skin, muscle, or bone infection with nontuberculous mycobacteria (NTM), which can manifest as chronic painless nodules that progress to purulent folliculitis and abscesses. NTM infection should be suspected when the patient's wound has been exposed to water, there is a history of surgery, and empirical anti-infection is ineffective. This is the first case of Mycobacterium senegalense infection caused by medical beauty, which tell people that they should be cautious when choosing medical aesthetic projects and medical aesthetic institutions.

OBJECTIVES: To develop the birth weight curve of twin neonates with a gestational age of 25-40 weeks, and to investigate the regional differences of the birth weight curve. METHODS: A total of 11 maternal and child health care hospitals with more than 7 000 neonates delivered annually were selected in 11 cities of China (Haikou, Guangzhou, Liuzhou, Guilin, Quanzhou, Shenzhen, Chongqing, Chengdu, Changsha, Ningbo, and Lianyungang), and all live twin neonates delivered in the 11 hospitals from January 1, 2017 to December 31, 2020 were enrolled for the development of birth weight curves. RESULTS: A total of 17 256 twin neonates with a gestational age of 25-40 weeks from the 11 cities were included in the study. The reference values of the 3rd-97th percentiles of birth weight of twin neonates for the total of the 11 cities and for each of the 11 cities in China were established, and the birth weight percentile curves were drawn. The birth weight curve level of twin neonates in Liuzhou was lower than the average level of the 11 cities; the birth weight curve level of twin neonates in Ningbo was higher than the average level of the 11 cities; the birth weight curve level of twin neonates in Lianyungang was obviously higher than the average level of the 11 cities; the birth weight curve level of twin neonates in other 8 cities was almost the same as the average level of the 11 cities. CONCLUSIONS The reference values of the 3rd-97th percentiles of birth weight of twin neonates for the total of the 11 cities and for each of the 11 cities are developed, which can be used as a reference for evaluating the intrauterine growth of twin neonates in the region. The level of intrauterine growth of twin neonates in some cities is different from the average level of the 11 cities of China.
