Jiegeng decoction is a classic prescription composed of two Chinese medicinal herbs： Platycodon grandiflorum and Glycyrrhiza uralensis. It has the efficacy of diffusing lung qi， resolving phlegm， relieving sore throat and discharging pus， and is commonly used in the treatment of respiratory diseases such as cough and pharyngodynia. This article reviews the chemical components， pharmacological mechanisms and clinical applications of Jiegeng decoction. It was found that Jiegeng decoction contains triterpenoid saponins， flavonoids， glycosides， acids， and other components， with platycodin D， platycodin D2， glycyrrhizic acid， glycyrrhetinic acid， liquiritin， etc.， serving as the main active pharmaceutical ingredients. Jiegeng decoction and its chemical constituents exert anti-inflammatory effects by inhibiting signaling pathways such as nuclear factor-κB and mitogen- activated protein kinases， and demonstrate anti-tumor activities through mechanisms like modulating the tumor immune microenvironment and promoting cancer cell apoptosis. Additionally， it exhibits various pharmacological actions including antibacterial， antiviral， and antioxidant effects. Clinically， Jiegeng decoction， its modified prescription and compound combinations are widely used in the treatment of respiratory diseases such as cough， pneumonia， and pharyngitis， as well as digestive system disorders like constipation.

This study explores the diagnosis and treatment of needle knife therapy for ankylosing spondylitis (AS) at middle and advanced stage based on the theory of meridian tendons, from a holistic perspective and syndrome differentiation. The treatment strategy includes "harmonizing yin and yang" to address root causes and "tendons-based release" to harmonize qi and blood, with the "tendons nodule points" as the core acupoint selection criterion. Based on this approach, the study systematically elaborates on two needle knife methods for AS: "governor vessel bone-piercing technique" and "below-the-umbilicus release technique", covering indications, acupoint location, and procedures. Clinical case examples are provided to enrich needle knife therapy guided by the theory of meridian tendons, offering insights for clinical and research work on AS.

Objective:To investigate the effect of subacute exposure of Di(2-ethylhexyl)phthalate(DEHP)on endometrial decidualization and early pregnancy miscarriage in mice.Methods:CD1 mice were orally administrated with 300(low-dose group),1000(medium-dose group),or 3000 mg·kg-1·d-1 DEHP(1/10 LD50,high-dose group)for 28 days,respectively.An early natural pregnancy model and an artificially induced decidualization model were established.The uterine tissues were collected on D7 of natural pregnancy and D8 of artificially induced decidualization,respectively.The effects of a subacute exposure to DEHP on the decidualization of mice were detected by HE staining,Masson staining,TUNEL assay,and Western blotting.A model of spontaneous abortion was constructed in mice after subacute exposure to 300 mg·kg-1·d-1 DEHP,and the effect of impaired decidualization on pregnancy was investigated by observing the pregnancy outcome on the 10th day of gestation.Results:Compared with the control group,the conception rate was significantly decreased in the high-dose DEHP subacute exposure group(P＜0.05).HE staining showed that,compared with the control group,the decidual stromal cells in the low-and medium-dose exposure groups were disorganized,the nuclei of the cells were irregular,the cytoplasmic staining was uneven,and the number of polymorphonuclear cells was significantly reduced.Masson staining showed that compared with the control group,the collagen fibers in the decidua region of the DEHP low-dose group and the medium-dose group were more distributed,more abundant and more disorderly.TUNEL assay showed increased apoptosis in the decidua area compared to the control group.Western blotting showed that the expression of BMP2,a marker molecule for endometrial decidualization,was significantly reduced(P＜0.05 or P＜0.01).The abortion rate and embryo resorption rate were increased,and the number of embryos,uterine wet weight,uterine area and placenta wet weight were decreased in DEHP low-dose group compared to the control group stimulated by mifepristone,an abortifacient drug(P＜0.05 or P＜0.01).Conclusion:Subacute exposure to DEHP leads to impaired endometrial decidualization during early pregnancy and exacerbates the risk of adverse pregnancy outcomes in mice.

ObjectiveTo investigate the therapeutic effect and mechanism of coptisine on chronic atrophic gastritis （CAG） in rats based on the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway. MethodA CAG rat model was induced by multiple factors， including sodium salicylate， N-methyl-N′-nitro-N-nitrosoguanidine （MNNG）， and irregular feeding. The successfully modeled rats were randomly divided into the model group， folic acid group， and high- and low-dose coptisine groups. The high- and low-dose coptisine groups were given coptisine （50， 10 mg·kg^-1， respectively）， and the folic acid group was given folic acid at 2 mg·kg^-1 for 60 days. The pathological changes were detected by hematoxylin-eosin （HE） staining. The ultrastructure of gastric mucosal cells was observed by electron microscopy. Serum pepsinogen Ⅰ （PGⅠ）， pepsinogen Ⅱ （PGⅡ）， and PGⅠ/PGⅡ ratio （PGR） were detected by immunoturbidimetry. Serum gastrin-17 （G-17） level was detected by radioimmunoassay. The content of interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） in serum of rats was detected by enzyme-linked immunosorbent assay （ELSIA）. Western blot analysis was used to detect the expression levels of TGF-β₁， PI3K， phosphorylated-Akt （p-Akt）， mTOR， and phosphatase and tensin homolog deleted on chromosome 10 （PTEN） in gastric mucosa. The mRNA levels of TGF-β₁， PI3K， Akt， mTOR， PTEN， microtubule-associated protein light chain 3Ⅱ （LC3Ⅱ）， and Beclin-1 were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the normal group， the model group showed atrophy and reduced number of intrinsic glands in the gastric mucosal tissues， as well as inflammatory cell infiltration. The ultrastructure of gastric mucosal cells in the model group displayed nuclear condensation， reduced and swollen mitochondria， and abnormal structure. The serum levels of G-17， PGⅠ， PGR， and the protein and mRNA levels of PTEN in gastric tissues were significantly lower in the model group （P<0.01）， while serum levels of IL-6， IL-1β， TNF-α， and the protein and mRNA levels of TGF-β₁， PI3K， Akt， and mTOR in gastric tissues were significantly higher （P<0.01）. Compared with the model group， various drug intervention groups showed different degrees of improvement in pathological damage and gastric mucosal cell ultrastructure， significantly increased serum levels of G-17， PGⅠ， and PGR （P<0.05，P<0.01）， and significantly decreased levels of IL-6， IL-1β， and TNF-α （P<0.05，P<0.01）. The high-dose coptisine group significantly downregulated the protein and mRNA levels of TGF-β₁， PI3K， Akt， and mTOR （P<0.05，P<0.01）. ConclusionBerberine has a therapeutic effect on CAG in rats， possibly exerting a protective effect on gastric mucosa by inhibiting inflammation and blocking the PI3K/Akt/mTOR signaling pathway.

A total of 16 pieces of evidence were summarized from nine aspects of rehabilitation exercise evaluation, principles, timing, methods, health education, psychotherapy, pain management, evaluation and post discharge follow-up.Conclusions:This study summarizes the best evidence for rehabilitation exercise in patients with lumbar spinal stenosis after surgery, and it suggests that healthcare professionals apply evidence based on clinical context and patient willingness.

Objective:To explore the clinical effects of the best evidence-based practice plan for rehabilitation exercises in patients undergoing surgery for lumbar spinal stenosis (LSS) .Methods:Guided by the evidence-based practice model of the Joanna Briggs Institute (JBI) Center for Evidence-Based Healthcare in Australia, the best evidence was combined with the clinical context to develop quality review indicators for clinical practice. In December 2022, a baseline review was conducted with 30 patients undergoing surgery for LSS (before evidence application). From December 2022 to February 2023, the baseline review results were analyzed to identify facilitating and obstructive factors between the current status and the review indicators, and improvement strategies were implemented based on available resources. In February 2023, another 30 patients (after evidence application) were selected to evaluate the post-application effects. The Japanese Orthopedic Association (JOA) score, Oswestry Disability Index (ODI), Tampa Scale for Kinesiophobia (TSK) score, General Self-Efficacy Scale (GSES) score, and quality of life scores were compared between the two groups at 24 hours, 1 month, 3 months, and 6 months postoperatively. The execution rate of clinical quality review indicators and the knowledge scores on rehabilitation exercises of 25 nurses before and after training were also compared.Results:There were no statistically significant differences in JOA scores, ODI, TSK scores, GSES scores, and quality of life scores between the two groups at 24 hours postoperatively ( P > 0.05). However, there were statistically significant differences in these scores at 1, 3, and 6 months postoperatively ( P< 0.01). After evidence application, the execution rate of seven clinical quality review indicators improved, and the knowledge scores on rehabilitation exercises of the 25 nurses increased significantly ( P< 0.05) . Conclusions:The evidence-based practice for rehabilitation exercises in patients undergoing surgery for LSS is safe and feasible. It standardizes evidence-based nursing practice behavior, enhances nurses' knowledge levels, effectively improves postoperative lumbar function, promotes physical rehabilitation, and enhances the quality of life.

Objective:To investigate the levels of family discharge readiness and discharge education quality in families of children with nephropathy, and to analyze the correlation between family discharge readiness and discharge education quality.Methods:From January to December in 2022, the primary caregivers of children with nephropathy in a tertiary hospital in Yinchuan( n=107) were investigated by general data questionnaire, Chinese version of readiness for hospital discharge scale-parent form and Chinese version of quality of discharge teaching scale-parent form.SPSS 26.0 software was used for statistical description of the data, Pearson correlation analysis was used for correlation between family discharge readiness and discharge guidance quality, and multiple linear stepwise regression analysis was used to identify factors affecting discharge readiness. Results:The total score of family discharge readiness was (130.90±10.69), and quality of discharge education was (140.99±6.31).Pearson correlation analysis showed that there was a positive correlation between family discharge readiness and discharge education quality ( r=0.962, P<0.05).The results of multiple linear regression showed that the quality of discharge education( β=0.973), length of hospital stay for the patients( β=0.987), primary caregivers( β=0.078) and their cultural levels( β=-0.093) were the main influencing factors on discharge readiness (all P<0.05). Conclusion:The quality of discharge education could significantly affect discharge readiness of children with nephropathy.Medical staff should improve the quality of discharge education and guidance, so as to promote the caregivers to be prepared for discharge and reduce unplanned re-admissions.

Purpose To investigate the relationship be-tween the expressions of CD3,CD4,CD8,CD20,CD68,PD-1 and PD-L1 and the clinical prognosis of peritoneal mesothelioma(PM).Methods Clinical data of 69 PM patients were collect-ed.EnVision two-step immunohistochemical method was used to detect the expression of CD3,CD4,CD8,CD20,CD68,PD-1 and PD-L1 in PM.Associations between expression levels and survival were estimated by univariate and multivariate Cox pro-portional-hazards models.Results There were no significant differences in the expressions of CD3,CD4,CD8,CD20,CD68,and PD-1 in tumor infiltrating lymphocytes(TILs)of ep-ithelioid and non-epithelioid PM.The expression of PD-L1 in non-epithelioid PM TILs was higher than that in epithelioid PM TILs,but the difference was not statistically significant.The median overall survival(mOS)time of PM was 19.1 months.Multivariate models identified asbestos exposure(P=0.002),PCI score(P=0.034),histological type(P=0.036),and CD4 expression(P=0.043)was independent prognostic factors for PM.Conclusion Asbestos exposure,PCI score,histologi-cal type and CD4 expression in TILs may exert significant im-pacts on survival of PM patients.
