ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy (DR). MethodsFourteen research centers participated in this study, which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group (120 cases) and a control group (120 cases). The observation group was treated with Tangning Tongluo tablets, and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision, DR progression rate, retinal microhemangioma, hemorrhage area, exudation area, glycosylated hemoglobin (HbA1c) level, and TCM syndrome score were assessed before and after treatment, and the safety was observed. ResultsThe vision changed in both groups after treatment (P<0.05), and the observation group showed higher best corrected visual acuity (BCVA) than the control group (P<0.05). The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups, while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment, the number of microhemangiomas decreased in both the observation group (Z=-1.437, P<0.05) and the control group (Z=-2.238, P<0.05), and it showed no significant difference between the two groups. As the treatment time prolonged, the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment, the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment, neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time, both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR, being capable of improving vision and reducing hemorrhage and exudation in the fundus.

Chinese Journal of Experimental Traditional Medical Formulae 2024;30(5):272-281
Xiaoyaowan has the effects of soothing the liver, invigorating the spleen, regulating menstruation, and nourishing blood. It is often used to treat the distending pain of the chest and hypochondriac, loss of appetite, dizziness, and irregular menstruation caused by liver depression and spleen deficiency. The formula originated from the Sinisan of Treatise on Cold Damage(《伤寒论》) in the Han dynasty and was officially formulated in the Song dynasty's Taiping Royal Prescriptions(《太平惠民合计局方》). In the Ming and Qing dynasties, it was developed into more comprehensive formulas such as modified Bazhentang, modified Xiaoyaowan, and other formulas. In recent years, Xiaoyaowan has become a classic formula for treating many symptoms of liver depression. The Pharmacopoeia of the People's Republic of China(《中华人民共和国药典》), 2020 edition, records Xiaoyaowan and modified Xiaoyaowan. Modern clinical research has further expanded the therapeutic range of this formula. Through literature research, it is found that there are certain reports on the clinical application and quality analysis of Xiaoyaowan, but the relevant literature lacks collation so far. Therefore, relevant literature was consulted and sorted out. The paper summarized the treatment of mammary hyperplasia, depression, irregular menstruation, melasma, menopausal syndrome, and polycystic ovary syndrome with Xiaoyaowan, as well as the quality analysis of paeoniflorin, ferulic acid, and glycyrrhizinic acid of Xiaoyaowan. It is expected to lay a foundation for further research on clinical application, pharmacodynamic mechanism, and quality control of this classic formula.

OBJECTIVE To study the antifungal activity of Huangqin decoction (HQD) against Trichophyton mentagrophytes and explore its mechanism. METHODS Minimal inhibitory concentration (MIC), minimal fungicidal concentration (MFC), mycelial length, spore germination rate, biomass and mycelium ultrastructure observation were performed to evaluate the antifungal activity of HQD against T. mentagrophytes. The effects of HQD on the cell wall of T. mentagrophytes were detected through sorbitol protection experiment. By measuring the content of ergosterol and the activities of squalene epoxide (SE) and lanosterol 14α-demethylase (CYP51), the activity of HQD on the cell membrane of T. mentagrophytes was investigated. The effects of HQD on T. mentagrophytes mitochondria were investigated by determining the activities of malate dehydrogenase (MDH), succinate dehydrogenase (SDH), and ATPases (including sodium potassium ATPase, calcium magnesium ATPase, and total ATPase). RESULTS HQD exhibited significant antifungal activity against T. mentagrophytes with MIC of 3.13 mg/mL and MFC of 25 mg/mL. After intervention with HQD, the mycelial length of T. mentagrophytes was significantly shortened (P<0.05); spore germination rate, biomass, the content of ergosterol in the cell membrane, the activities of SE and CYP51 in the cell membrane and MDH, SDH and ATPase in mitochondria were all decreased significantly (P<0.05); cell structure had been ;damaged to a certain extent, but the integrity of the cell wall had not been affected. CONCLUSIONS HQD shows significant antifungal activity against T. mentagrophytes, the mechanism of which may be associated with reducing the 0791- content of ergosterol in the cell membrane and the activities of SE, CYP51, and mitochondria-related enzymes.

Objective To analyze the epidemiological characteristics and epidemic situation of children with Kashin-Beck disease (KBD) in China,and provide the basis for formulating prevention and control measures. Methods Fixed-point monitoring,moving-point monitoring,and full coverage of monitoring were promoted successively from 1990 to 2023. Some children (7-12 years old) underwent clinical and right-hand X-ray examinations every year. According to the KBD diagnosis criteria,clinical and X-ray assessments were used to confirm the diagnosis. Results In 1990,the national KBD detectable rate was 21.01%. X-ray detection decreased to below 10% in 2003 and below 5% in 2007. Between 2010 and 2018,the prevalence of KBD in children was less than 0.4%,which fluctuated at a low level,and has decreased to 0% since 2019. Spatial epidemiological analysis indicated a spatial clustering of adult patients prevalence rate in the KBD areas. Conclusion The evaluation results of the elimination of KBD in China over the last 5 years showed that all villages in the monitored areas have reached the elimination standard. While the adult KBD patients still need for policy consideration and care.

BackgroundDomestic researches on the professional identity of psychiatrists are still relatively rare up to now, and effective evaluation tools remain inadequate. ObjectiveTo construct a professional identity questionnaire for psychiatrists with high reliability and validity, so as to provide an effective tool for the evaluation of professional identity of psychiatrists. MethodsA self-designed questionnaire titled "Professional Identity Questionnaire" was compiled. After preliminary screening of items and expert consultation, an initial questionnaire was formed and administered to a sample of 400 psychiatrists, and the final questionnaire was assessed by item analysis, reliability analysis and validity analysis. ResultsThe Cronbach's α coefficient was 0.930 for the final questionnaire, and ranged from 0.817 to 0.920 for each dimension. The value of KMO was 0.904 (χ2=2 931.652, P<0.01). The cumulative variance contribution rate of factors extracted from exploratory factor analysis was 68.306%. Confirmatory factor analysis showed that the integrity of fit indexes were χ2/df=1.234, GFI=0.905, NFI=0.916, RMSEA=0.036, CFI=0.983, IFI=0.983. The final version of the professional identity questionnaire for psychiatrists consisted of 23 items relating to 4 dimensions, namely, professional cognition, professional behavior, professional emotion and professional values. ConclusionThe professional identity questionnaire for psychiatrists has good reliability and validity, and can be used as an effective tool to evaluate the professional identity of psychiatrists.

Objective To study the effect and mechanism of high glucose on mesothelial-mesenchymal transition(MMT)of peritoneal mesothelial cells(HMrSV5),and the protective effect of pharmacological blocking of signal transducer and activator of transcription 3(STAT3)on rat peritoneal fibrosis(PF)model.Methods The animals were divided into three groups:the sham group,the model group,and the STAT3 inhibitor group.A miniature per-itoneal dialysis catheter was implanted under the dorsal skin of rat and the rat peritoneal fibrosis model was induced by daily injection of high glucose dialysate.After 10 weeks,HE staining was used to evaluate the histology of the peritoneum,and the level of transforming growth factor-β1(TGF-β1)in the peritoneum was measured by immuno-histochemistry.HMrSV5 was cultured in high glucose and the optimal stimulation concentration of high glucose was determined by Western blot.High glucose was used to stimulate HMrSV5 after successful transfection with si-STAT3 and Western blot was used to measure the protein level of STAT3,p-STAT3,and the key enzymes of glycol-ysis 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3(PFKFB3)and lactate dehydrogenase A(LDHA).Results HE staining showed that administration of STAT3 inhibitor(BP-1-102)could inhibit the thickening of subperitoneal tissue and the proliferation of vessels in HG dialysis rats.The expression of TGF-β1 in the rats perito-neum of the model group was significantly higher than that in the sham group,and the level of TGF-β1 was marked-ly lower in the STAT3 inhibitor group compared to the model group(P<0.05).Compared to the control group,high glucose induced the up-regulation of α-smooth muscle actin(α-SMA),the down-regulation of E-cadherin and STAT3 activation in HMrSV5(P<0.05).Mesothelial cells treated with high glucose also exhibited high expres-sion of the key enzymes of glycolysis(PFKFB3,LDHA)(P<0.05),and si-STAT3 can effectively inhibit the overexpression of PFKFB3 and LDHA induced by high glucose(P<0.05).Conclusion STAT3 is involved in high glucose-induced HMrSV5 hyperglycolysis and MMT,and targeting STAT3 alleviates peritoneal fibrosis and an-giogenesis during peritoneal dialysis treatment in rats.

ObjectiveTriple-negative breast cancer (TNBC) is the breast cancer subtype with the worst prognosis, and lacks effective therapeutic targets. Colony stimulating factors (CSFs) are cytokines that can regulate the production of blood cells and stimulate the growth and development of immune cells, playing an important role in the malignant progression of TNBC. This article aims to construct a novel prognostic model based on the expression of colony stimulating factors-related genes (CRGs), and analyze the sensitivity of TNBC patients to immunotherapy and drug therapy. MethodsWe downloaded CRGs from public databases and screened for differentially expressed CRGs between normal and TNBC tissues in the TCGA-BRCA database. Through LASSO Cox regression analysis, we constructed a prognostic model and stratified TNBC patients into high-risk and low-risk groups based on the colony stimulating factors-related genes risk score (CRRS). We further analyzed the correlation between CRRS and patient prognosis, clinical features, tumor microenvironment (TME) in both high-risk and low-risk groups, and evaluated the relationship between CRRS and sensitivity to immunotherapy and drug therapy. ResultsWe identified 842 differentially expressed CRGs in breast cancer tissues of TNBC patients and selected 13 CRGs for constructing the prognostic model. Kaplan-Meier survival curves, time-dependent receiver operating characteristic curves, and other analyses confirmed that TNBC patients with high CRRS had shorter overall survival, and the predictive ability of CRRS prognostic model was further validated using the GEO dataset. Nomogram combining clinical features confirmed that CRRS was an independent factor for the prognosis of TNBC patients. Moreover, patients in the high-risk group had lower levels of immune infiltration in the TME and were sensitive to chemotherapeutic drugs such as 5-fluorouracil, ipatasertib, and paclitaxel. ConclusionWe have developed a CRRS-based prognostic model composed of 13 differentially expressed CRGs, which may serve as a useful tool for predicting the prognosis of TNBC patients and guiding clinical treatment. Moreover, the key genes within this model may represent potential molecular targets for future therapies of TNBC.

Acute kidney injury(AKI)is a common critical condition in clinical practice,characterized by a rapid decline in renal function within a short period.The pathogenesis of AKI is complex and has not been fully elucidated.In recent years,studies have found that the activation of endoplasmic reticulum stress(ERS)and the Nod-like receptor family pyrin domain containing 3(NLRP3)inflammasome are closely related to the occurrence of AKI.When the kidneys is damaged,the internal environment of the kidney cells is disrupted,leading to the activation of ERS.Excessive ERS can induce apoptosis of renal cells,leading to the occurrence of AKI.Additionally,the NLRP3 inflammasome can mediate the recognition of endogenous and exogenous danger signal molecules by the host,subsequently activating caspase-1,pro-inflammatory cytokines such as IL-1β and IL-18,inducing inflammatory responses,and promoting apoptosis of renal cells.In animal models of AKI,the upregulation of ERS markers is often accompanied by increased expression levels of NLRP3 inflammasome-related proteins,indicating that ERS can regulate the activation process of the NLRP3 inflammasome.Clarifying the role and mechanism of ERS and NLRP3 inflammasome in AKI is expected to provide new insights for the prevention and treatment of AKI.
