OBJECTIVE: To assess the safety and topical efficacy of prim-O-glucosylcimifugin (POG) and investigate the molecular mechanisms of its therapeutic effects in atopic dermatitis (AD). METHODS: The effects of POG on human keratinocyte cell viability and its anti-inflammatory properties were evaluated using cell counting kit-8 assay and reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Subsequently, the impact of POG on the differentiation of cluster of differentiation (CD) 4⁺ T cell subsets, including T-helper type (Th) 1, Th2, Th17, and regulatory T (Treg), was examined through in vitro experiments. Network pharmacology analysis was used to elucidate POG's therapeutic mechanisms. Furthermore, the therapeutic potential of topically applied POG was further evaluated in a calcipotriol-induced mouse model of AD. The protein and transcript levels of inflammatory markers, including cytokines, lymphocyte-specific protein tyrosine kinase (Lck) mRNA, and LCK phosphorylation (p-LCK), were quantified using immunohistochemistry, RT-qPCR, and Western blot analysis. RESULTS: POG was able to suppress cell proliferation and downregulate the transcription of interleukin 4 (Il4) and Il13 mRNA. In vitro experiments indicated that POG significantly inhibited the differentiation of Th2 cells, whereas it exerted negligible influence on the differentiation of Th1, Th17 and Treg cells. Network pharmacology identified LCK as a key therapeutic target of POG. Moreover, the topical application of POG effectively alleviated skin lesions in the calcipotriol-induced AD mouse models without causing pathological changes in the liver, kidney or spleen tissues. POG significantly reduced the levels of Il4, Il5, Il13, and thymic stromal lymphopoietin (Tslp) mRNA in the AD mice. Concurrently, POG enhanced the expression of p-LCK protein and Lck mRNA. CONCLUSION Our research revealed that POG inhibits Th2 cell differentiation by promoting p-LCK protein expression and hence effectively alleviates AD-related skin inflammation.

Inflammatory bowel disease (IBD) is characterized by chronic relapsing intestinal inflammation and encompasses ulcerative colitis (UC) and Crohn's disease (CD). IBD has emerged as a global healthcare problem. Clinically efficacious therapeutic agents are deficient. This study concentrates on models of ulcerative colitis with the objective of discovering novel therapeutic strategies. Previous investigations have established that schisandrin A demonstrates anti-inflammatory effects in vitro, concurrently enhancing the transcriptional activity of farnesoid X receptor (FXR). FXR inversely modulates the transcriptional activity of NF-κB, which has an important role in regulating inflammatory responses. Consequently, the current study was to explore the safeguarding influence of schisandrin A on ulcerative colitis and delineate the mechanism by which it regulates this effect through the FXR signaling pathway. The effect of schisandrin A on the mRNA levels of inflammatory factors was evaluated in RAW264.7 cells. The dual luciferase reporter gene assay was used to verify the relationship between schisandrin A and FXR targeting. The animal experiments were performed in accordance with the regulations of the Animal Ethics Committee of Shanghai University of Traditional Chinese Medicine (approval No. PZSHUTCM2304250005). Acute ulcerative colitis was induced in wild-type or FXR knockout C57BL/6 mice by drinking 3% dextran sodium sulfate (DSS) for 7 days, and schisandrin A was administered via gavage for a continuous treatment period of 7 days. The body weight and faecal were monitored daily. The mRNA levels of inflammatory factors in colon tissue and FXR target genes were measured by RT-qPCR. The findings revealed that schisandrin A, in vitro, impeded the lipopolysaccharide (LPS)-induced elevation in mRNA levels of inflammatory factors and schisandrin A could augment transcriptional activity of FXR. In wild-type mice, schisandrin A significantly improved weight loss, colon shortening, loose stools and blood in stools in mice with acute ulcerative colitis, and schisandrin A significantly reduced the expression of pro-inflammatory factors genes and significantly increased the expression of FXR target genes in colon tissues. In FXR knockout mice, the administration of schisandrin A failed to yield ameliorative effect on acute ulcerative colitis in mice. In conclusion, schisandrin A can reduce intestinal inflammation through the FXR signaling pathway to alleviate acute ulcerative colitis in mice. Implications arise that Schisandra lignans could serve as lead compounds for drug development aimed at inflammatory bowel disease.

Objective To observe the effect of dapagliflozin on Klotho protein and renal function in elderly patients with diabetic kidney disease(DKD),and explore the related factors affecting the level of Klotho protein.Methods A total of 88 elderly DKD patients admitted to the Affiliated Hospital of Xuzhou Medical University from January 2021 to November 2021 were randomly divided into dapagli-flozin group and control group.The patients were treated for 12 weeks.The body weight,blood pressure,blood glucose,Klotho protein,renal function,urinary albumin/creatinine(UACR)were estimated before and after treatment,respectively,and adverse reactions were recorded.Results After treatment,the decrease degree of body weight,body mass index,systolic blood pressure,diastolic blood pres-sure,blood urea nitrogen(BUN),serum uric acid,cystatin C,UACR and the increase degree of Klotho protein were greater in dapagli-flozin group than those in the control group(P＜0.001).Multiple linear regression analysis showed that age,BUN and UACR were inde-pendent related factors affecting the level of Klotho protein.There was no significant difference in adverse events between the two groups(P＞0.05).Conclusion Dapagliflozin treatment can reduce body weight,blood pressure,improve renal function and increase the level of Klotho protein.The regulatory effect of dapagliflozin on Klotho protein may be one of the important mechanisms of its renal protection.

Objective:To analyze the impact of transcervical resection of adhesion (TCRA) on obstetric complications in patients after frozen-thawed embryo transfer (FET) and its associated factors.Methods:A retrospective cohort study was conducted by collecting clinical data from patients who underwent autologous oocyte FET treatment and gave birth to at least one live newborn at the Reproductive Medicine Center of Nanjing Women and Children's Healthcare Hospital from April 2015 to May 2022. Based on the uterine condition, patients were divided into three groups: control group with normal uterine morphology (712 cases); the intrauterine adhesion (IUA) group consisting of IUA patients who did not undergo TCRA surgery (45 cases); the TCRA group, which included IUA patients who received TCRA treatment (51 cases). The relationship between uterine conditions and obstetric complications among the three groups was investigated using propensity score matching (PSM). Multivariate logistic regression analysis was applied to identify risk factors associated with obstetric complications related to TCRA. The performance of the constructed multivariate logistic regression model was evaluated using calibration curves and receiver operating characteristic (ROC) curves.Results:1) Before PSM, statistically significant differences were observed among the three groups regarding endometrial thickness, the presence of a scarred uterus, numbers of pregnancies, deliveries, miscarriages, induced abortions, and transferred embryos (all P<0.05). After PSM, baseline characteristics were balanced across the groups. The rates of placenta accreta spectrum disorders (PAS) in the TCRA group [48.8% (20/41)] and the IUA group [45.2% (19/42)] were significantly higher than those in control group [24.7% (18/73), P=0.016; 22.8% (18/79), P=0.019]. 2) Multivariable logistic regression analysis revealed that endometrial thickness ( OR=0.79, 95% CI: 0.69-0.90, P<0.001], number of pregnancies (2 times, OR=2.25, 95% CI: 1.33-3.82, P=0.003), endometrial preparation protocol (gonadotropin-releasing hormone agonist plus hormone replacement therapy, OR=2.29, 95% CI: 1.16-4.52, P=0.017), the presence of a scarred uterus ( OR=2.19, 95% CI: 1.39-3.45, P<0.001), and uterine cavity conditions (IUA and TCRA, OR=2.11, 95% CI: 1.07-4.17, P=0.031; OR=2.70, 95% CI: 1.37-5.31, P=0.004) were independent predictors of PAS occurrence. 3) The area under the ROC curve for this model was 0.732 (95% CI: 0.686-0.778). Calibration curve results, after internal validation, showed good consistency between predicted risks and actual outcomes, demonstrating good discriminative ability and calibration ( P=0.540). Conclusion:The incidence of obstetric complications such as placenta previa, postpartum hemorrhage, and premature rupture of membranes in patients who underwent TCRA surgery was comparable to that of patients with a normal uterine morphology. However, TCRA significantly increased the risk of PAS in patients with IUA undergoing FET assisted reproductive treatment.

Establish a production line with controllable process and high intelligence, contribute to improve the quality and production efficiency of aconite processed by microwave, and promote the transformation and application of aconite processed by microwave. According to the principle of aconite detoxification and the characteristics of industrial microwave equipment, an industrial production line of aconite processed by microwave was established with diester alkaloids and monoester alkaloids as indicators, and pilot production was carried out. At the same time, the content of active constituents and efficacy were compared with that of the main processed products, such as Shengfupian, Baifupian and Heishunpian. The results showed that the industrial production of aconite processed by microwave can be divided into two stages: "Liquid seal to detoxification - drying and puffing". The content of monoester alkaloids in 10 batches of aconite processed by microwave was 0.071%-0.166% and the content of diester alkaloids was 0.004%-0.016%, which met the relevant requirements of the Chinese Pharmacopoeia in 2020. Compared with Heishunpian and Baifupian, the retention rate of the effective components of aconite processed by microwave was higher. Pharmacological experiments showed that aconite processed by microwave not only retained the anti-inflammatory and analgesic activities of Heishunpian and Baifupian, but also significantly increased the levels of leukocytes and lymphocytes in mice with liver cancer chemotherapy, enhanced the CD4/CD8 ratio in spleen cells of mice (P < 0.05), thus regulating the body's immunity. However, this effect of Baifupian was weak, while Heishunpian and Shengfupian had no such effect. Through the above research, this study established microwave processing line with controllable process and high intelligence, as well produced the aconite processed by microwave with low toxicity and stable quality. It laid a foundation for the industrialized continuous production and clinical positioning of aconite by microwave processed, and provided scientific support for the development and application of microwave technology in the field of traditional Chinese medicine. All animal experiments in this study were reviewed and approved by the Experimental Animal Ethics Committee of Chengdu University of Traditional Chinese Medicine before being carried out (Approval No. 2020-28).

Objective: To evaluate the thermal environment of different types of public places and the thermal comfort of employees, so as to provide scientific basis for the establishment of microclimate standards and health supervision requirements. Methods: From June 2019 to December 2021, 50 public places (178 times) of 8 categories in Wuxi were selected, including hotels, swimming pools (gymnasiums), bathing places, shopping malls (supermarkets), barber shops, beauty shops, waiting rooms (bus station) and gyms. In summer and winter, microclimate indicators such as temperature and wind speed were measured in all kinds of places, combined with the work attire and physical activity of employees in the places. Fanger thermal comfort equation and center for the built environment (CBE) thermal comfort calculation tool were used to evaluate the predicted mean vote (PMV), predicted percent dissatisfied (PPD) and standard effective temperature (SET) according to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 55-2020. The modification effects of seasonal and temperature control conditions on thermal comfort were analyzed. The consistency of GB 37488-2019 "Hygienic Indicators and Limits in Public Places" and ASHRAE 55-2020 evaluation results on thermal environment was compared. Results: The thermal sensation of hotel, barber shop staff and the gym front-desk staff were moderate, while the thermal sensation of swimming place lifeguard, bathing place cleaning staff and gym trainer were slightly warm in summer and winter. Waiting room (bus station) cleaning and working staff, shopping mall staff felt slightly warm in summer and moderate in winter. Service staff in bathing places felt slightly warm in winter, while staff in beauty salons felt slightly cool in winter. The thermal comfort compliance of hotel cleaning staff and shopping mall staff in summer was lower than that in winter (χ(2)=7.01, 7.22, P=0.008, 0.007). The thermal comfort compliance of shopping mall staff in the condition of air conditioning off was higher than that in the condition of air conditioning on (χ(2)=7.01, P=0.008). The SET values of front-desk staff in hotels with different health supervision levels were significantly different (F=3.30, P=0.024). The PPD value and SET value of the front-desk staff, and the PPD value of cleaning staff of hotels above three stars were lower than those of hotels below three stars (P<0.05). The thermal comfort compliance of front-desk staff and cleaning staff in hotels above three stars was higher than that in hotels below three stars (χ(2)=8.33, 8.09, P=0.016, 0.018). The consistency of the two criteria was highest among waiting room (bus station) staff (100.0%, 1/1) and lowest among gym front-desk staff (0%, 0/2) and waiting room (bus station) cleaning staff (0%, 0/1) . Conclusion: There are different degrees of thermal discomfort in different seasons, under the condition of air conditioning and health supervision, and the microclimate indicators can not fully reflect the thermal comfort of human body. The health supervision of microclimate should be strengthened, the applicability of health standard limit value should be evaluated in many aspects, and the thermal comfort of occupational group should be improved.
