ObjectiveTo explore the mechanism of Yishen Huashi granules in alleviating renal tubular epithelial cell injury and relieving diabetic kidney disease by regulating the mitogen-activated protein kinase （MAPK） signaling pathway. MethodsThe db/db mice of 12 weeks old were randomly assigned into model ， dapagliflozin （1.6 mg·kg^-1）， and Yishen Huashi granules （4.7 g·kg^-1）， and db/m mice were used as the control group. The general conditions of mice were observed， and fasting blood glucose and 24-h urinary protein and albumin-to-creatinine ratio （ACR） were measured at weeks 0 and 12 of administration. After 12 weeks of treatment， the levels of serum creatinine （SCr）， blood urea （UREA）， triglycerides （TG）， total cholesterol （TC）， and low density lipoprotein （LDL） were measured. The pathological changes in the renal tissue were observed by hematoxylin-eosin （HE） staining， Periodic acid-Schiff （PAS） staining， Mallory staining， and transmission electron microscopy. Real-time PCR was employed to determine the mRNA levels of monocyte chemotactic protein-1 （MCP-1） and CC chemokine receptor-2 （CCR2） in the renal tissue of mice. The immunohistochemical assay was employed to examine the expression of p38， phospho-p38 （p-p38）， MCP-1， and CCR2 in the renal tissue of mice. Western blotting was employed to measure the protein levels of p-p38， p38， MCP-1， and CCR2 in the renal tissue of mice.HK-2 cells cultured in vitro were grouped as follows： negative control， high glucose（30 mmol·L^-1）， Yishen Huashi granule-containing serum， and SB203580. After 48 h of cell culture in each group， RNA were extracted and the levels of MCP-1， and CCR2 mRNA were determined by Real-time PCR，proteins were extracted and the levels of p38， p-p38， MCP-1， and CCR2 were determined by Western blot. ResultsThe in vivo experiments showed that before treatment， other groups had higher body weight， blood glucose level， 24 h urinary protein， and ACR than the control group （P<0.05，P<0.01）. After 12 weeks of treatment， compared with the model group， the Yishen Huashi granules group showed improved general conditions， a decreasing trend in body weight， lowered levels of blood glucose， 24-h urinary protein， and ACR （P<0.01）， reduced SCr and UREA （P<0.01）， and declined levels of TC， TG， and LDL （P<0.05，P<0.01）. Compared with the model group， the Yishen Huashi granules group showed alleviated damage and interstitial fibrosis in the renal tissue as well as reductions in glomerular foot process fusion and basement membrane thickening. Moreover， the Yishen Huashi granules group showed down-regulated mRNA levels of MCP-1 and CCR2 （P<0.01）， reduced positive expression of p-p38， MCP-1， and CCR2 （P<0.01）， and down-regulated protein levels of p-p38/p38， MCP-1， and CCR2 （P<0.05） in the renal tissue. The cell experiment showed that compared with the high glucose group， the Yishen Huashi granule-containing serum group showcased down-regulated mRNA levels of MCP-1 and CCR2 （P<0.01） and down-regulated protein levels of p-p38/p38， MCP-1， and CCR2（P<0.05，P<0.01）. ConclusionYishen Huashi granules can regulate glucose-lipid metabolism， reduce 24 h urinary protein and ACR， improve the renal function， alleviate the renal tubule injury caused by high glucose， and protect renal tubule epithelial cells in db/db mice by reducing MCP-1/CCR2 activation via the p38 MAPK signaling pathway.

The accumulation of uremic toxins such as urea nitrogen, blood creatinine, and uric acid of patients with renal failure in vivo would lead to aggravated kidney damage. In this study, coated aldehyde oxy-starch (CAO) was used as an adsorbent to investigate its in vitro adsorption performance on renal failure indexes for urea, indoxyl sulfate (INS), monomethylamine (MMA), dimethylamine (DMA), uric acid (UA), and creatinine (Cr). The effects of variables such as pH, temperature, concentration, dosage, and time on the adsorption capacity of CAO were systematically investigated, employing analytical techniques of high-performance liquid chromatography (HPLC) and gas chromatography (GC). The results revealed that CAO exhibited a strong adsorption capacity for urea, INS, and MMA, alongside a moderate adsorption capacity for DMA, UA, and Cr. The adsorption kinetics and thermodynamic studies indicated that the adsorption of urea and UA by CAO were fitted in pseudo-first-order kinetics, and the adsorption isotherm aligned with the Freundlich adsorption model. The enthalpy change ΔH of urea in adsorption was in the range of 40 to 60 kJ·mol^-1, which demonstrated the presence of strong adsorption force due to the interactions of coordinating groups. The ΔH of UA was greater than 80 kJ·mol^-1, indicating the generation of chemical bonds during the adsorption. Both of them, Gibbs free energy ΔG was less than 0, within the range of -20 to 0 kJ·mol^-1, suggested that the adsorption of urea and UA by CAO occurred spontaneously as physical adsorption process. The adsorption entropy ΔS of urea and UA was > 0, which indicated an increase in entropy throughout the adsorption. The infrared spectroscopygram showed the formation of a chemical bond, specifically the imine bond, following the adsorption of urea by CAO, thereby indicating a chemical reaction during the adsorption. This study elucidates the adsorption mechanism of CAO on various indexes of renal failure, providing a scientific basis for its clinical usage.

ObjectiveTo investigate the mechanism of Shenkang injection in delaying diabetic kidney disease by regulating endoplasmic reticulum stress and attenuating podocyte apoptosis through the Glucose regulated protein 78 （ GRP78 ） / transcription factor C / EBP homologous protein （ CHOP ） signaling pathway （GRP78/CHOP） signaling pathway. MethodsFor the animal experiment， 10 12-week-old db/m mice were selected as a normal group， and 30 12-week-old db/db mice were randomly divided into a model group， a Shenkang injection group （15.6 mL·kg^-1）， and a dapagliflozin group （1.6 mg·kg^-1）. To observe the general condition of mice， fasting blood glucose， urinary albumin/urine creatinine （ACR）， and 24 h urine protein quantification were detected in each group before drug administration. After 12 weeks of drug treatment， mice were tested for fasting blood glucose， total cholesterol （TC）， triglyceride （TG）， low-density cholesterol （LDL）， ACR， 24 h urine protein quantification， blood creatinine （SCr）， and blood urea （UREA）. Hematoxylin-eosin （HE） staining， periodic acid-Schiff （PAS） staining， and transmission electron microscopy were used to observe the pathologic morphology in renal tissue. Immunohistochemistry was used to detect the expressions of nephroprotective marker protein （Nephrin）， glucose-regulated protein 78 （GRP78）， CCAAT/enhancer-binding protein homologous protein （CHOP）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in renal tissue. Western blot was used to detect the expressions of GRP78， CHOP， Bcl-2， Bax， and Nephrin proteins， and Real-time polymerase chain reaction （Real-time PCR） was employed to detect the expressions of Nephrin， GRP78， CHOP， Bcl-2， and Bax mRNAs in renal tissue. ResultsBefore drug administration， compared with those in the normal group， the body mass of db/db mice was significantly increased， and blood glucose， 24 h urine protein quantification， and ACR were significantly elevated in the Shenkang injection group and Dapagliflozin group （P<0.01）. After 12 weeks of administration， compared with those in the model group， the general state of mice in the Shenkang injection group was significantly improved， and the body mass was decreased. The blood glucose was significantly reduced （P<0.01）， and blood lipids TC， TG， and LDL were significantly decreased （P<0.05， P<0.01）. The 24 h urine protein quantification and ACR were significantly decreased （P<0.05）， and SCr and UREA were significantly reduced （P<0.01）. Compared with those of the model group， the pathologic results of the Shenkang injection group showed that proliferation of mesangial cells， reduction of inflammatory cell infiltration， and alleviation of renal tubular vacuolization and podocyte damage were observed in renal tissue of mice. Electron microscopy showed that fusion of the pedicle protruding and thickening of the basement membrane were reduced. Immunohistochemistry results showed that the expressions of GRP78， CHOP， and Bax proteins were significantly reduced （P<0.01）， and the expressions of Nephrin and Bcl-2 proteins were significantly increased （P<0.01） in renal tissue of the Shenkang injection group. Western blot results showed that the expressions of Nephrin and Bcl-2 in the Shenkang injection group were significantly increased （P<0.05， P<0.01）， and the expressions of GRP78， CHOP， and Bax proteins were significantly decreased （P<0.05， P<0.01）. Real-time PCR results showed that the expressions of GRP78， CHOP， and Bax mRNAs were down regulated in the Shenkang injection group （P<0.01）， and the expressions of Nephrin and Bcl-2 mRNAs were up regulated （P<0.01）. ConclusionShenkang injection inhibits endoplasmic reticulum stress response and podocyte apoptosis by regulating the GRP78/CHOP signaling pathway， which in turn ensures the integrity of glomerular filtration barrier， reduces the occurrence of proteinuria， improves renal function， and thus delays the progression of diabetic kidney disease.

Objective: To investigate the clinical efficacy and safety of pudendal nerve modulation (PNM) in the treatment of female pudendal neuralgia (PN)，so as to promote the clinical application of this technique. Methods: A retrospective analysis was conducted on 20 female PN patients who failed conservative treatment at Gongli Hospital during Nov.2020 and Oct.2023.All patients underwent simultaneous PNM and sacral nerve modulation (SNM) with the assistance of 3D printing navigation.Dual-stage test electrodes for PNM and SNM were implanted，followed by alternate therapeutic trial for each modality.Secondary conversion rates and longitudinal outcomes，including visual analogue score (VAS)，patient health questionnaire-9 (PHQ-9)，and quality of life (QoL) scores were compared preoperatively，post-stage Ⅰ，and at 3，6，and 12 months post-stage Ⅱ. Results: All operations were successful.After the trial phase，the secondary conversion rate for PNM was significantly higher than that for SNM; 16 patients (16/20，80%) chose the second-phase PNM implantation surgery，3 (3/20，15%) chose second-phase SNM implantation，and 1 (1/20，5%) had electrodes removed due to ineffective results from both trials.Further assessment revealed that the improvements in VAS，PHQ-9，and QoL scores for PNM patients were significantly better than those for SNM patients after the first phase of surgery and at 3，6 and 12 months after the second-phase conversion (P<0.05).No complications such as electrode migration or infection were observed during the follow-up of 12-15 months. Conclusion: PNM provides more effective relief of pain symptoms and improvements in depressive states for female PN patients compared to SNM.With the assistance of 3D printing navigation，the operation is simple and safe，and offers stable therapeutic effects.It is worthy of clinical promotion and application.

Objective:To investigate the effects of ubiquitin-specific protease (USP) 7/47 inhibitor (Cat. No. 1247825-37-1) on the proliferation and apoptosis of acute myeloid leukemia (AML) cells with or without internal tandem duplications of the Flt3 gene (Flt3-ITD). Methods:ATP assay was used to detect the effects of 1247825-37-1 on the cell viability of two AML cell lines (MOLM13 and MV4-11) harboring Flt3-ITD mutation and one AML cell line (THP-1) without Flt3-ITD mutation as well as the primary Flt3-ITD-mutant and non-mutant AML cells from patient samples. Flow cytometry was used to detect the apoptosis of AML cell lines treated by different concentrations of 1247825-37-1.Results:Compared with the control group, 1247825-37-1 was able to significantly inhibit the proliferation of MOLM13, MV4-11 and THP-1 cells ( P<0.000 1). Besides, the cell viability of primary AML cells was also inhibited by 1247825-37-1, and a stronger inhibitory effect on non-mutant AML cells was observed. The USP7/USP47 inhibitor 1247825-37-1 could inhibit the proliferation of AML cells in a dose-dependent manner and a low dose (2 or 4 μmol/L) of 1247825-37-1 would be effective. Moreover, 1247825-37-1 was also able to efficiently induce the apoptosis of above AML cell lines in a dose-dependent manner. Conclusions:The USP7/USP47 inhibitor 1247825-37-1 significantly inhibits the proliferation of AML cells with or without Flt3-ITD mutation.

Objective: To evaluate the effect of Tai Chi and Qigong on patients with lumbar disc herniation (LDH). Methods: Relevant data were retrieved from nine English and Chinese databases, including Cochrane Library, PubMed, and Wanfang Data, etc. from inception to June 2024. All published randomized controlled trials assessing the effect of Tai Chi and Qigong on visual analog scale (VAS), Japanese Orthopedic Association (JOA) score, and other health indicators in participants with LDH compared to usual medical care or other treatments were included. Grey literature, trials involving the pushing of hands (Tui Shou) or Tai Chi with weapons, and trials with co-interventions (Tai Chi/Qigong plus another treatment) were excluded. Methodological quality was analyzed using the Cochrane risk of bias tool, and evidence quality was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool. Results: Fourteen trials (954 patients) were included in this study. Tai Chi and Qigong were associated with lower VAS pain scores (standardized mean difference −0.55, 95% confidence interval [CI] −0.95 to −0.15, P = .01), higher JOA scores (mean difference [MD] 4.40, 95% CI 2.62 to 6.18, P < .001) and straight leg raise test results (MD 9.40°, 95% CI 7.64 to 11.15, P < .001) in patients with LDH. Furthermore, compared with usual care, Tai Chi and Qigong showed enhanced effects on pain and JOA scores. When compared to other exercises or massage, the effect on pain scores was similar but that on JOA scores was significant. Conclusions Tai Chi and Qigong may have favorable effects on VAS pain and JOA scores compared with usual care, and on JOA scores compared with other exercises or massage in patients with LDH. Given the overall poor quality of the evidence, the results of current study should be interpreted cautiously.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.
