Objective To investigate the mechanism of inducing macrophage polarization induced by acupoint effect of electroacupuncture to promote the repair of acute skeletal muscle injury.Methods 45 SD rats were randomly divided into blank group,model group,electroacupuncture group(EA group),sodium chrominate group (DSCG group) and electroacupuncture+sodium chrominate group (hereinafter referred to as EA+DSCG group),with 9 rats in each group. The rats in the EA group and the EA+DSCG group were subjected to EA intervention at the right "Chengshan" (BL57) and "Yanglingquan"(GB34),with a frequency of 2 Hz/100 Hz. The gait changes of rats were recorded by animal gait analyzer. The morphological changes of the right gastrocnemius were observed by HE staining. The changes of mast cell aggregation and degranulation in local skin muscles of "chengshan" point were observed by toluidine blue staining. The expressions of Pax7,MyoD and skin mast cells and 5-HT in the right gastrocnemius were detected by immunofluorescence method. The positive expressions of CD68 and CD206 in right gastrocnemius macrophage was observed by immunohistochemical staining.Results Compared with blank group,the wiggle time of the right hind leg in model group and DSCG group increased,stride length decreased,HE staining showed inflammatory cell infiltration,myocyte enlargement,degeneration and necrosis. The degranulation rate of local skin mast cells in "Chengshan" (BL57) area increased,and the expressions of mast cell tryptase,5-HT,Pax7,MyoD,CD68 and CD206 increased (P<0.05). Compared with model group,the wiggle time of the right hind leg in EA group and EA+DSCG group decreased,stride length increased,HE staining showed that inflammatory cell infiltration was reduced,muscle cells were uniform in size and arranged neatly. Mast cell degranulation rate increased significantly in EA group,and the expressions of mast cell tryptase,5-HT,Pax7,MyoD and CD206 increased (P<0.05),while CD68 expression decreased (P<0.05). Compared with EA+DSCG group,the degranulation rate of mast cells and the expressions of mast cell tryptase,5-HT,Pax7,MyoD and CD206 increased (P<0.05),while CD68 expression decreased in EA group (P<0.05). Conclusion EA "Chengshan" (BL57) and "Yanglingquan" (GB34) can stimulate acupuncture points to locally induce mast cell degranulation,promote the polarization of macrophages,and then activate muscle satellite cells to play the regulatory process of repairing skeletal muscle injury.

Objective To observe the role of dried tangerine peel in Yigong Powder improves iron metabolism and promotes red blood cell generation in anemia of chronic disease (ACD).Methods With a two-by-two factorial design,the Yigong Powder was divided into dried tangerine peel and Chenpi absent Decoction. According to the random number table method,32 zymosan-induced generalized inflammation (ZIGI) mice were randomly divided into the model group,the dried tangerine peel group,the Chenpi absent Decoction group,and the Yigong Powder group. The dried tangerine peel group,Chenpi absent Decoction group and the Yigong Powder group were given dried tangerine peel(3.083 g/kg),Chenpi absent Decoction(12.33g/kg),and Yigong Powder(15.413g/kg)by gavage to the corresponding group of mice. The model group was given an equal amount of physiological saline by gavage,and treated continuously for 7 days. After the completion of administration,the body weight of each group of mice was recorded. The hemoglobin content of each group of mice was detected using a fully automatic cell counter,the serum iron content was detected using colorimetry,the serum ferritin content was detected using enzyme-linked immunosorbent assay (ELISA),and the spleen index was calculated. The liver tissue inflammatory factors interleukin-1β (IL-1β),interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α),interferon-γ (IFN-γ),interleukin-4 (IL-4),and interleukin-10 (IL-10) levels were detected using Luminex method. The mRNA expressions of liver tissue hepcidin gene (HAMP) and membrane iron transporter ( Fpn) were detected using real-time fluorescence PCR method. Results Dried tangerine peel and Chenpi absent Decoction both showed interactive effects in regulating hemoglobin,serum iron,serum ferritin content,improving spleen index,and regulating the mRNA expressions of HAMP,Fpn,as well as IL-1β and IFN-γ (P<0.05). Compared with the model group,dried tangerine peel significantly increased hemoglobin,serum iron content,and Fpn mRNA expression in ZIGI model mice,while decreasing ferritin content,spleen index,HAMP mRNA expression,and the levels of IL-1β,IL-6,TNF-α,and IFN-γ (P<0.05). Chenpi absent Decoction significantly increased serum iron content and Fpn mRNA expression in ZIGI model mice,while reducing spleen index,ferritin content,HAMP mRNA expression,and the levels of IL-1β and IFN-γ、IL-4 (P<0.05). Conclusion The effects of dried tangerine peel on inflammatory factors (IL-6 and TNF-α) and Fpn may play a key role in the improvement effects of Yigong Powder on ACD and iron metabolism.

Diabetic gastroparesis (DGP) is a common diabetic neuropathy that affects the normal function of gastric motility and emptying. Clinically, it often manifests as abdominal distension, nausea and vomiting, early satiety, dyspepsia, etc. The pathogenesis of DGP is multifactorial, closely related to many factors, such as chronic hyperglycemia, neuropathy, autonomic nervous system disorders, inflammation, and oxidative stress. These factors can interact with each other, leading to delayed gastric emptying and the occurrence of related symptoms. Traditional Chinese medicine (TCM) has significant advantages in the prevention and treatment of DGP, including a long history, remarkable efficacy, individualized treatment, diverse therapeutic formulations, and improvement in the quality of life. Additionally, TCM is known for its low adverse reactions, good tolerance, and multi-targeted effects, making it an important approach in the management of DGP. Previous research has found that the main mechanisms of Chinese medicine in the prevention and treatment of DGP include the regulation of gastrointestinal hormones, inhibition of inflammatory responses, reduction of oxidative stress, enhancement of interstitial cells of Cajal activity, inhibition of pyroptosis, and modulation of related signaling pathways such as stem cell factor (SCF)/cellular growth factor receptor (c-Kit), adenosine monophosphate-activated protein kinase (AMPK), Ras homologous genome member A (RhoA)/Rho-associated coiled-coil forming kinase (ROCK). This article primarily summarized the research progress on Chinese medicine in preventing and treating DGP through the inhibition of inflammatory responses, reduction of oxidative stress, enhancement of interstitial cells of Cajal activity, inhibition of pyroptosis, and regulation of related signaling pathways, aiming to provide a reference and basis for further research on the application value of Chinese medicine in the prevention and treatment of DGP.

Objective:To analyze the incidence and progression of overactive bladder(OAB)symp-toms following radical prostatectomy for prostate cancer patients and to identify related risk factors.Methods:A retrospective study was conducted on 263 local stage prostate cancer patients who underwent radical prostatectomy at Peking University Third Hospital from January 2013 to May 2017.Clinical base-line information,comprehensive imaging features,perioperative parameters,preoperative urinary control status,pathological diagnosis,and the incidence of OAB within one year postoperatively were collected and analyzed.In the imaging features,two parameters were defined:Bladder wall thickness(BWT)and bladder mucosal smoothness(BMS),which were used to predict the occurrence of OAB.Patients were evaluated based on their clinical baseline characteristics,including age,body mass index(BMI),co-morbidities,and prostate-specific antigen(PSA)levels.The imaging characteristics were assessed using preoperative MRI,focusing on BWT and BMS.Perioperative parameters included operative time,blood loss,and length of hospital stay.The OAB symptoms were assessed using the overactive bladder symptom score(OABSS)and the international prostate symptom score(IPSS).These scores were correlated with the postoperative incidence of OAB.Results:Among the 263 patients who underwent radical prostatecto-my,52(19.8%)exhibited OAB within one year postoperatively.Of the 40 patients with preoperative OAB symptoms,17(42.5%)showed remission postoperatively,while 23(57.5%)had persistent symptoms.Additionally,29 patients developed new-onset OAB,accounting for 55.77%of all postopera-tive OAB cases.Univariate analysis indicated that BWT,BMS,OABSS,and IPSS score were all associ-ated with the occurrence of postoperative OAB.Further multivariate analysis identified BMS as an inde-pendent risk factor for long-term OAB(P<0.001).Conclusion:Long-term postoperative overactive bladder is a common complication following radical prostatectomy.The findings suggest that preoperative MRI measurements of bladder wall thickness and bladder mucosal smoothness during bladder filling phase can predict the risk of OAB occurrence postoperatively.Identifying these risk factors preoperatively can help in counseling patients about potential complications and in developing strategies to mitigate the risk of developing OAB after surgery.Early detection and management of these parameters might improve the quality of life for patients undergoing radical prostatectomy.

Objective:To summarize the content and effects of exercise interventions for stroke survivors, providing references for medical and nursing personnel in formulating exercise intervention plans for these patients.Methods:Literature on exercise interventions for stroke survivors was searched in databases such as China National Knowledge Infrastructure, Wanfang, VIP, China Biology Medicine disc, Cochrane Library, PubMed, Embase, and Web of Science up to May 1, 2023. Data extraction and summarization were conducted on the included literature.Results:Twenty-two articles were included in the review. The exercise types for stroke survivors primarily involved aerobic and resistance training; the intensity was mainly moderate to high; the frequency was mostly 3-5 times per week, with each session lasting 30-60 minutes; and the duration of interventions ranged from as short as two weeks to as long as one year. Exercise interventions improved stroke survivors' functional mobility, quality of life, cardiopulmonary function, mental state, cognitive function, fatigue, sleep, and compliance to varying degrees.Conclusions:Exercise interventions have achieved positive outcomes in stroke survivors. In the future, medical and nursing personnel can incorporate patient preferences into exercise intervention plans while ensuring patient safety to promote rehabilitation.

Objective:To investigate whether endoplasmic reticulum transmembrane protein IRE1(encoded by Ern1)can modulate the immunogenicity and tumorigenicity of cancer cells and explore the underlying mechanism.Methods:Correlation between ERN1 expression and the overall survival of cancer patients was explored with public cancer databases.CRISPR-Cas9 technology was used to delete Ern1 in mouse tumor cell lines MCA205 and TC-1.By CCK-8,flow cytometry,ELISA,luciferase reporter systems,subcutaneous tumor models,prime-boost regimens,we analyzed impact of Ern1 on tumor cell proliferation in vitro and tumor growth in vivo,intratumoral immune cell composition,tunicamycin-induced immunogenic cell death and activation of anti-tumor effector T cells.The growth kinetics of Ern1-/-tumors was also monitored in Ifnar-/-mice.Results:ERN1 expression was found to be negatively correlated with the overall survival of cancer patients across multiple cancer types.Although Ern1 deficiency didn't affect tumor cell proliferation in vitro,it largely delayed tumor growth or caused spontaneous tumor regression in immune-competent mice.As compared to wild type counterparts,Ern1-/-tumors harbored much more neutrophils but significantly less CD4+T cells.Upon tunicamycin-induced endoplasmic reticulum stress,Ern1-/-cells were more vulnerable to cell death.Although Ern1-deficiency reduced HMGB1 release and calreticulin exposure,IFN-α/β secretion was increased,and strongly elevated type Ⅰ IFN response in tumor cells and augmented IFN-γ production by anti-tumor effector T cells.Ern1-/-tumor cells restored the tumorigenic capacity in Ifnar-/-mice.Conclusion:Ern1 defi-ciency can enhance the immunogenicity of tumor cells and inhibit tumor outgrowth by boosting endoplasmic reticulum stress-induced type Ⅰ IFN response.

Objective:To compare the clinical efficacy of fluorescent laparoscopy versus conventional laparoscopy for living-donor hepatectomy and explore the application value of fluorescent cholangiography in pediatric living donor liver transplantation (LT) using left lateral lobe.Methods:From October 2016 to August 2023, retrospective analysis was conducted for the relevant clinical data from 302 recipients of laparoscopic left lateral lobe donor hepatectomy. There were 90 cases in conventional laparoscopy group and 212 cases in fluorescent laparoscopy group. After propensity score matching (PSM), 88 patients were enrolled into each group. The perioperative data such as operative duration, donor liver thermal ischemic time, number of graft bile duct openings, liver function parameters and complication rates at Day 1/3 postoperation of donors and recipients were compared between two groups. SPSS 27.0 statistical software was utilized for analysis. Independent sample t, Mann-Whitney U and chisquare tests were utilized for examining the inter-group differences. Results:In fluorescent laparoscopy group, the proportion of grafts with a single open left hepatic duct was 84.1 %(74/88) versus 70.5% (62/88) in conventional laparoscopy group with statistically significant difference ( P=0.031). No statistically significant inter-group differences existed in postoperative liver function recovery or short-term postoperative complications ( P>0.05 ). No statistically significant inter-group differences existed in short-term postoperative liver function recovery or hospitalization length ( P> 0.05). In terms of biliary complications, fluorescent laparoscopy group had no biliary complications while the incidence of biliary complications was 3.4% (3/88) in conventional laparoscopy group. However, inter-group difference was statistically insignificant ( P>0.05 ) . Conclusions:Living-donor LT using left lateral lobe under fluorescent laparoscopy may enhance the surgical safety for both donors and recipients.
