Objective To systematically assess the efficacy and safety of combining acupoint massage with lactulose for constipation treatment.Methods Randomized controlled trials on the effects of acupressure combined with lactulose on constipation were searched in PubMed,Web of Science,Cochrane Library,Embase,China National Knowledge Infrastructure,SinoMed,VIP and Wanfang Data Knowledge Service Platform.The search timeframe was from the establishment of the database to July 2024,and Meta-analysis was performed using RevMan5.3 and Stata15.1 software.Results A total of 8 randomized controlled trials including 675 study participants were included.Meta-analysis showed that the acupoint massage combined with lactulose group was superior to control group in terms of total effective rate,abdominal distension score,and constipation quality of life score.Furthermore,its recurrence rate was lower than that of control group.Both groups showed no statistically significant difference in adverse reactions(P＞0.05).Conclusion Acupressure combined with lactulose can effectively improve the efficiency and quality of life in the treatment of constipation,and can be safe.Due to the limitation of the quantity and quality of the included literature,more high-quality studies with long-term follow-up are still needed to supplement and validate the above conclusions in the future.

OBJECTIVE This study evaluates the role of Gelation metnacrylate(GelMA)hydrogel loaded with hPT H(3-34)(29-34)short peptide in the healing of chronic infectious skin wounds in diabetic rats.METHODS Ex-perimental rats were divided into control group,GelMA group and GelM A+hPTH(3-34)(29-34)group,with 15 rats in each group.Diabetic rat models were prepared,and chronic infectious skin wounds were constructed.Differences in wound area changes,wound healing-related indicator[type Ⅰ collagen α1 chain(COL1A1),α-smooth muscle actin(α-SMA),platelet endothelial cell adhesion molecule-1(CD31),matrix metalloproteinase-9(MMP9)and cyclooxygenase-2(Cox2)]expression and migration ability of fibroblasts in vitro were compared a-mong the groups.RESULTS Compared with the control group,the wound area of rats in the GelMA group de-creased on Day 7 and Day 14(P＜0.05),and the wound area of rats in the GelM A+hPTH(3-34)(29-34)group decreased on Day 3,Day 7 and Day 14(P＜0.05).Compared with the GelMA group,the wound area of rats in the GelM A+hPTH(3-34)(29-34)group decreased on Day 3,Day 7 and Day 14(P＜0.05).Compared with the control group,on Day 7 after modeling,the expression of COL1A1,α-SMA and CD31 in rats was upregulated,and in the GelM A+hPTH(3-34)(29-34)group showed a greater increase than in the GelMA group(P＜0.05),while the expression of MMP9 and Cox2 was downregulated,and in the GelMA+hPTH(3-34)(29-34)group showed a greater decrease than in the GelMA group(P＜0.05).Compared with the control group,on Day 7 af-ter modeling,the relative activity of NLRP3,IL-6,TNF-α,IL-1β and Caspase-1 in rats decreased,and in the GelM A+hPTH(3-34)(29-34)group showed a greater decrease than in the GelMA group(P＜0.05).On Day 7 after modeling,the relative scratch distance of fibroblasts derived from the wound tissue in the GelMA+h PT H(3-34)(29-34)group was greater than that in the GelMA group,which was greater than that in the control group(P＜0.05).CONCLUSIONS The GelMA hydrogel loaded with hPTH(3-34)(29-34)short peptide can effectively accelerate the wound healing process and enhance tissue repair and structural reconstruction by inhibiting the activ-ity of the NLRP3 inflammasome pathway,demonstrating its potential to improve wound healing efficiency.

Objective To investigate the effects of Aurora kinase A(AURKA)on the tumor microenvironment of colorectal cancer(CRC)and to predict the active compounds in Chinese herbs that can target AURKA.Methods Based on the transcriptomic data and clinical information from 380 CRC tissues and 51 paracancerous tissues in The Cancer Genome Atlas(TCGA)database,the infiltration of different cells in the tumor tissues was analyzed using xCell and the binding of active compounds of Chinese herbs with AURKA was predicted through molecular docking.Results The expression of AURKA was significantly upregulated in CRC tissues compared with that in paracancerous tissues(P＜0.05),and CRC patients with high AURKA expression had shorter overall survival.Compared with the AURKA low-expression group,the abundance of macrophages,monocytes,and effector memory CD4+and CD8+T cells was significantly downregulated in the AURKA high-expression group(P＜0.05).In addition,the cytotoxicity of T cells was significantly reduced(P＜0.05).Further analysis revealed that AURKA expression was positively correlated with the abundance of myeloid-derived suppressor cells(MDSCs)and the expression levels of their chemokines CXCL2 and CXCL5(P＜0.05).Genes that were differentially expressed between the AURKA high-and low-expression groups were mainly enriched in monocyte migration,chemokine-induced cellular responses,and other related processes.Chinese herbal compounds,including hesperidin,aristololactam A Ⅱ a,anacardic acid,coumestrol,and 17β-estradiol,all showed binding energies to AURKA lower than-1.2 kcal/mol,indicating a certain level of binding stability.Among these Chinese herbal compounds,17β-estradiol exhibited the best binding stability to AURKA-3UOL.Conclusion The high expression of AURKA in CRC tissues suggests a poor clinical prognosis.AURKA can promote the development of a suppressive immune microenvironment in CRC,and 17β-estradiol,an active compound from Chinese herbs,is a potential therapeutic agent targeting AURKA.

Objective:To compare the safety and efficacy of high-dose- rate interstitial brachytherapy and particle implantation radiotherapy in the treatment of lymph nodes with pelvic metastases in the field after external radiotherapy.Methods:Clinical data of 42 patients with residual or newly metastatic pelvic lymph nodes after radiotherapy at Cangzhou Integrated Traditional Chinese and Western Medicine Hospital who met the inclusion criteria from January 2017 to April 2020 were retrospectively analyzed. Among them, 12 patients were male and 30 females, aged 39-82 years, (61.6±9.64) years on average. According to the treatment method, all patients were divided into the high-dose-rate interstitial brachytherapy group ( n=18) and particle implantation radiotherapy group ( n=24). During 3-year follow-up, the local control rate (LCR), incidence of complications and overall survival (OS) were compared between two groups. Age and operation time conforming to normal distribution were analyzed by t-test. The remaining indexes were analyzed by the Chi-square test or Fisher's exact test. The OS and LCR were calculated by Kaplan-Meier method. Results:There was no significant difference in baseline data between two groups (all P>0.05). The operation time in the high-dose- rate interstitial brachytherapy group was longer than that in the particle implantation radiotherapy group [(66.39±11.07) : (45.75±9.19) min, P<0.001]. During subsequent follow-up, there was no significant difference in the LCR between two groups (1-year LCR 88.9% vs. 87.5%, P=0.927; 2-year LCR 72.2% vs. 62.5%, P=0.874). There was no significant difference in the median OS between two groups (31.6 vs. 29.8 months, P=0.798). There was no significant difference in the incidence of early complications between two groups [ (4/18) vs. 5/24 (20.8%), P=1.000]. No late complications observed. Conclusion:High-dose- rate interstitial brachytherapy yields equivalent efficacy and safety to particle implantation radiotherapy in the treatment of lymph nodes with pelvic metastases.
