ObjectiveTo investigate the mechanism of the modified of Bazhentang combined with Guishentang in improving pregnancy outcomes in mouse models of embryo implantation dysfunction by regulating T helper 1/T helper 2 （Th1/Th2） immune balance. MethodsEighty ICR female mice were randomly divided into four groups （n=20 per group） on gestational day 1 （GD1）： control， model， western medicine， and traditional Chinese medicine （TCM） groups. Except for the control group， all mice received mifepristone solution （0.2 mg/mouse） via oral gavage on GD4 to induce embryo implantation dysfunction. The TCM group received a water decoction of the modified of Bazhentang combined with Guishentang （20.8 g·kg^-1）， with the western medicine group administered dydrogesterone （3.9 mg·kg^-1）， and the control/model groups given equal volumes of saline. All treatments were administered once daily from GD1 until one day before sample collection. Outcomes included implantation site counts （macroscopic observation）， pregnancy rates， body weight， endometrial histopathology （hematoxylin-eosin staining）， uterine expression of T-box expressed in T cells （T-bet）， GATA-binding protein 3 （GATA3）， interferon gamma （IFN-γ）， and interleukin-4 （IL-4） at protein （Western blot） and mRNA （real-time polymerase chain reaction， Real-time PCR） levels， serum IFN-γ and IL-4 levels （enzyme-linked immunosorbent assay， ELISA）， and Th1/Th2 immune balance evaluated by calculating T-bet/GATA3 and IFN-γ/IL-4 ratios. ResultsCompared to the control group， the model group showed no significant change in pregnancy rate but exhibited a marked reduction in average implantation sites and body weight （P<0.01）. Histopathological analysis revealed endometrial abnormalities， including decreased glandular density， stromal compaction， and absence of nucleolar vacuoles. At the molecular level， uterine tissue in the model group demonstrated significantly upregulated expression of T-bet and IFN-γ （P<0.05， P<0.01）， alongside markedly downregulated GATA3 and IL-4 expression （P<0.05， P<0.01）. Serum analysis confirmed markedly elevated IFN-γ （P<0.01） and reduced IL-4 levels （P<0.01）， resulting in significantly increased T-bet/GATA3 and IFN-γ/IL-4 ratios （P<0.01）. Compared to the model group， pregnancy rates in all treatment groups showed no significant change. Implantation sites and body weight increased substantially （P<0.01）， with restored endometrial morphology characterized by enhanced glandular density， stromal edema， and reappearance of nucleolar vacuoles. Significant downregulation of T-bet and IFN-γ （P<0.01） and upregulation of GATA3 and IL-4 （P<0.05， P<0.01） in uterine tissue were observed. Serum IFN-γ levels were significantly reduced （P<0.05， P<0.01）， while IL-4 levels were significantly elevated （P<0.05）. The Th1/Th2 ratios were significantly decreased （P<0.01）. ConclusionThe modified of Bazhentang combined with Guishentang significantly enhances the number of embryo implantation sites in mice with embryo implantation dysfunction， potentially through modulating T-bet/GATA3 expression， restoring Th1/Th2 immune balance， and improving endometrial receptivity.

During the Yan’an period， the party and government employed forms of health propaganda that were popular among the masses， focusing on superb medical skills and public feedback， as well as the strategy of skillfully using narrative techniques to carry out doctor-patient communication， which collectively created the image of good doctors characterized by “firm belief， superb medical skills， effective communication， and a friendly and approachable demeanor.” They were not only guardians of the people’s health but also the solid pillars of the success of the revolutionary cause. In the journey of the new era， contemporary medical professionals should deeply grasp the spiritual core of good doctors in the Yan’an period， uphold the leadership of the Communist Party of China， harbor a benevolent heart， and earn the trust and respect of patients through sincere humanistic care and superb medical services， so as to collectively promote the development of medical undertakings and contribute their strength to building a healthy China.

Objective: To observe the effect of Xipayimaizibizi oral liquid (XP) in an overactive bladder (OAB) experimental rat model and to explore its pharmacological mechanisms. Methods: Network pharmacology was used to explore the potential mechanisms of action of XP. The rats underwent bladder outlet obstruction surgery and were administered the corresponding drug concentrations by gavage for 4 weeks. The study observed the body weight, water intake, bladder and kidney indices (to evaluate their general status), urination behavior pattern (to observe frequency and urgency), and urodynamics (to measure bladder parameters). Hematoxylin and eosin and Masson's trichome staining were used to observe changes in the bladder structure. Enzyme-linked immunosorbent assay was used to measure the levels of nerve growth factor, brain-derived neurotrophic factor, and acetylcholine in the urine. The key targets involved in these mechanisms were validated using reverse transcription-quantitative polymerase chain reaction, immunohistochemistry, and western blot in vivo/vitro experiments. Result: Network pharmacological analysis predicted that XP may alleviate OAB by affecting the cholinergic synapse and calcium signaling pathways. XP treatment significantly reduced the bladder index, improved urine behavior and urodynamic parameters, decreased the neurotransmitters in urine, and reduced the thickness of the bladder wall and collagen ratio. These results indicate that XP can alleviate OAB symptoms and improve the bladder structure. In vivo/vitro experiments further demonstrated that XP can inhibit targets, such as muscarinic acetylcholine receptor 2, and participate in cholinergic synapses to further regulate the parasympathetic nervous system. It can also reduce the overexpression of Ca2+ caused by agonists, inhibit targets such as transient receptor potential vanilloid type 1, and participate in calcium signaling pathways to maintain Ca2+ homeostasis. Conclusion These results suggest that XP inhibited bladder overactivity by maintaining Ca2+ homeostasis and regulating the parasympathetic nervous system.

Objective:To investigate corneal transparency alteration in patients with type 2 diabetes and its influencing factors.Methods:A case-control study was conducted.A total of 52 patients with type 2 diabetes mellitus (DM) (104 eyes) and 23 age-matched healthy controls (46 eyes) were enrolled as DM group and normal control group in the Second Affiliated Hospital of Anhui Medical University from October 1, 2020 to October 30, 2021.Patients with DM were further divided into non-diabetic retinopathy (non-DR) and DR groups according to their fundus conditions.Corneal densitometry (CD) was evaluated using the Pentacam.According to its built-in program, the cornea was divided into anterior, intermediate, and posterior layers and subdivided into 0-2 mm, >2-6 mm, >6-10 mm, and >10-12 mm annular regions with the corneal apex as the center of the circle.Pentacam automatically calculated the CD value of each corneal layer and region as well as the total CD value.The influencing factors of total CD value in diabetes group were analyzed by a multivariate linear regression analysis model.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of the Second Affiliated Hospital of Anhui Medical University (No.YX2023-129[F1]).Written informed consent was obtained from each subject before any medical examination.Results:The total CD value of diabetes group was 20.24±3.10, which was significantly higher than 18.79±3.31 of normal control group ( t=-2.583, P=0.011).The CD values of the anterior layer, intermediate layer, 0-2 mm, and >2-6 mm regions were significantly higher in diabetes group than in normal control group (all at P<0.05).The CD values in the anterior layer were higher in non-DR and DR groups than in normal control group, and the CD values and total CD values in the middle and posterior layers were higher in non-DR group than in normal control group and DR group, and the differences were statistically significant (all at P<0.05).The CD values in the 0-2 mm and >2-6 mm regions were significantly higher in non-DR group than in normal control group, and the CD value in the >6-10 mm annular region was significantly higher in non-DR group than in DR group and normal control group (all at P<0.05).Multivariate linear regression analysis showed that age and glycosylated hemoglobin (HbA1c) level were the main influencing factors for the increase in CD values in diabetic patients ( β=0.266, P<0.001; β=0.423, P=0.003). Conclusions:The decrease of corneal transparency precedes the appearance of DR in patients with diabetes.Poor control of HbA1c level in diabetic patients may cause the decline of corneal transparency.

Objective:To investigate the prevalence of uremic pruritus (UP) in patients with peritoneal dialysis and its association with life behaviors.Methods:A total of 255 patients with peritoneal dialysis were followed up in Peritoneal Dialysis Center of Hangzhou Hospital of Traditional Chinese Medicine from October to December 2023 were enrolled. The general clinical data, disease awareness, treatment, and lifestyle behaviors (smoking, drinking, diet, bathing, and exercising etc) were compared between patients with or without UP, and among patients with different severity of UP.Results:Among 255 peritoneal dialysis patients, there were 144 UP cases with a prevalence rate of 56.5%, including 55 cases with mild itching (38.2%), 61 cases with moderate itching (42.4%), and 28 cases with severe itching (19.4%). The awareness rate of UP was 22.2% (32/144), the treatment rate of UP was 12.5% (18/144). There were significant differences in bath frequency (χ 2=7.03), and using alkaline body wash (χ 2=6.47) between UP group and non-UP group ( P<0.05). The severity of UP was associated with old age (≥60 years, Z=-3.13), low educational levels (primary school or lower, Z=-3.56), less water drinking (<500 ml/d, H=18.01), more spicy food and meat ( H=9.34), bath more than 3 times per week ( H=10.96), and using alkaline body wash ( H=6.57) (all P<0.05). Conclusion:Peritoneal dialysis patients have a high incidence of UP and a low rate of knowledge and treatment, and it is necessary to strengthen the health education and to modify their life behaviors in order to reduce the incidence of UP.

Objective:To evaluate the effect of long-term full-dose cognitive digital therapy on improving and maintaining cognitive function in patients with cognitive disorders, and to provide basis for nursing management of patients with cognitive disorders.Methods:This study adopted three parallel randomized control trial design. By adopting the method of continuous grouping and convenient sampling, from January 2020 to January 2023, 90 patients with cognitive disorders who were treated in the neurology outpatient department of Beijing Xuanwu Hospital of Capital Medical University were selected as the study objects. These patients were divided into the control group, outpatient group and home group with 30 patients in each group by using the random digit table method. The control group received routine nursing, patients in the outpatient group received cognitive digital therapy in clinic based on routine nursing, and patients in the home group received cognitive digital therapy at home based on routine. Before intervention, 6 and 12 months after intervention, Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were compared among three groups.Results:A total of 85 patients were enrolled in three groups. There were 28 cases in the control group, including 12 males and 16 females, aged (64.68±11.26) years. There were 30 patients in the outpatient group, including 19 males and 11 females, aged (65.74 ± 8.44) years. There were 27 cases in the home group, including 14 males and 13 females, aged (66.81 ± 11.18) years. The MMSE scores of the control group before intervention, 6 and 12 months after intervention were (22.00 ± 4.82), (17.25 ± 5.15), (14.25 ± 4.54) points respectively, and those of the outpatient group were (22.26 ± 3.46), (22.93 ± 3.77), (22.30 ± 3.57) points, while those of the home group were (22.40 ± 3.72), (22.03 ± 3.76), (21.90 ± 4.08) points respectively. The analysis of variance of repeated measurements showed that the intergroup, time and interaction effects were statistically significant ( Fbetween-group=15.30, Ftime=4.10, Finteraction=20.25, all P<0.05). The total scores of MoCA in the control group were (16.50 ± 4.87), (12.64 ± 4.94), (9.89 ± 4.01) points before intervention, 6 and 12 months after intervention, (18.74 ± 4.22), (18.96 ± 4.31), (18.41 ± 4.34) points in the outpatient group, (17.20 ± 5.12), (16.93 ± 3.67), (16.93 ± 4.10) points in the home group respectively. The analysis of variance of repeated measurements showed that the intergroup, time and interaction effects were statistically significant ( Fbetween-group=16.30, Ftime=5.74, Finteraction=12.08, all P<0.05). Conclusions:Long-term adequate outpatient and in-home cognitive digital therapy can effectively improve and maintain cognitive function in patients with cognitive disorders. It optimizes the management scheme of cognitive function training and provides evidence-based basis for non-drug intervention of patients with cognitive disorders.

Objective:To investigate the clinical efficacy of Cyclosporine A(CsA)in patients with unexplained repeated implantation failure(URIF),and to analyze the changes of peripheral blood lymphocyte subsets after CsA treatment.Methods:105 patients with URIF who underwent frozen-thawed embryo transfer(FET)in the De-partment of Reproductive Medicine in The Second Affiliated Hospital of Kunming Medical University from Septem-ber 30,2021 to March 1,2022 were selected.After informed consent,the patients were divided into CsA group(n=52)and control group(n=53)according to whether they received CsA treatment or not.Pregnancy outcomes and changes in lymphocyte subset were compared between the two groups.Results:The embryo implantation rate and clinical pregnancy rate in CsA group were higher than those in the control group,the difference was statisti-cally significant(48.91%vs.32.56%,P=0.027;53.85%vs.32.08%,P=0.024).The CsA group had a lower ear-ly abortion rate than the control group(10.71%vs.23.53%),but the difference was not statistically significant(P=0.25).The percentage of CD3-CD16+CD56+in CsA group was significantly decreased after treatment[(16.15±5.37)%vs.(18.23±7.10)%,P=0.012],it was also lower than that in the control group[(16.15±5.37)%vs.(18.67±5.16)%,P=0.018].Conclusions:CsA treatment can significantly improve the clinical preg-nancy rate and embryo implantation rate of frozen-thawed embryo transfer in patients with URIF,which may be a-chieved by promoting the distribution of peripheral blood lymphocytes to the direction of embryo implantation,es-pecially by down-regulating the percentage of CD3-CD16+CD56+.CsA has a certain application prospect in the field of assisted reproduction.
