The shaoyang meridian is an important pivot between the internal organs and meridians system， with the functions of regulating qi and blood， balancing yin and yang， and coordinating the ascending and descending movement of qi. Dysfunction of the shaoyang pivot can lead to spleen and kidney deficiency， impaired liver and gallbladder qi regulation， and stagnation of qi and blood. It is believed that the onset and progression of Crohn's disease are closely related to shaoyang pivot dysfunction， with the core pathogenesis characterized by shaoyang disharmony， spleen deficiency， dampness retention， and blood stasis. Based on this understanding， the treatment principle centers on harmonizing the shaoyang pivot， supplemented by methods such as warming and nourishing the spleen and stomach， tonifying shaoyang， and soothing the liver and benefiting the gallbladder. Acupuncture is employed to target key acupoints along the shaoyang meridian to restore its regulatory functions， improve spleen and stomach transformation and transportation， facilitate liver and gallbladder qi flow， and promote the circulation of qi and blood. This provides a practical therapeutic approach for acupuncture-based treatment of Crohn's disease.

Objective:To observe the effect of pecking moxibustion on the pattern characteristics of redness,swelling,heat,and pain in the affected joints,also the synovial cell ultrastructure in rats with rheumatoid arthritis(RA)due to damp heat affecting bones/joints,and to explore the anti-inflammatory mechanism of pecking moxibustion in treating the early stage of RA. Methods:Eighteen rats were randomly selected from 78 female ones as the blank group,and all the other rats were subjected to preparing the"differentiation of disease and pattern"RA model due to damp heat affecting bones/joints by using the method of"collagen-induced arthritis plus windy,damp,and hot environment stimulation".Fifty-four rats with successful modeling were randomly divided into a model group,a drug group,and a pecking moxibustion group,with 18 rats in each group.Rats in the drug group were given methotrexate at a dose of 1 mg/(kg·bw)on the 1st,8th,and 15th days.Rats in the pecking moxibustion group were treated with pecking moxibustion at Quchi(LI11),Dazhui(GV14),and Ashi points,and each point was treated with moxibustion for 15 min every day and a total of 3 courses of treatment,with 6 d as a course of treatment.After treatment,the capillary permeability,joint swelling,joint surface temperature,and plantar thermal pain threshold of the diseased joints in rats were observed,and the ultrastructural changes of synovial cells were observed by transmission electron microscopy. Results:The local swelling,surface temperature,and Evans blue(EB)leakage volume were significantly higher(P<0.05),the thermal pain threshold was significantly lower(P<0.05),and the synovial cell ultrastructure was obviously damaged in the affected joints in the model group compared with the blank group.The swelling degree,surface temperature,and EB leakage volume were significantly reduced(P<0.05),the thermal pain threshold was significantly increased(P<0.05),and the ultrastructural abnormalities of synovial cells were significantly improved in the diseased joints in the drug group and the pecking moxibustion group compared with the model group.The thermal pain threshold of rats in the pecking moxibustion group was significantly improved compared with the drug group(P<0.05). Conclusion:Pecking moxibustion obviously improves the pattern characteristics of local redness,swelling,heat,and pain in the diseased joints of rats with RA due to damp heat affecting bones/joints and effectively repairs the ultrastructure of the damaged synovium.It suggests that the pecking moxibustion intervention has a significant anti-inflammatory effect on early RA.

Objective:To investigate the role of serotonin reuptake transporter(SERT)and P2X3 receptor of dorsal root ganglion(DRG)in regulating visceral hypersensitivity of rats with irritable bowel syndrome(IBS)by electroacupuncture(EA). Methods:Male Sprague-Dawley and SERT-/-rats were subjected to preparing IBS visceral hypersensitivity models with 2,4,6-trinitrobenzene sulfonic acid(TNBS)enema.Three weeks post-modeling,interventions including EA,intrathecal injection,and EA plus intrathecal injection were applied,respectively.Hematoxylin-eosin staining and abdominal withdrawal reflex(AWR)score were used to confirm the successful establishment of the IBS model.AWR score,whole-cell patch clamp technique,and Western blotting assay were used to evaluate the changes in visceral pain sensitivity,electrophysiological properties of DRG neurons,and the expression of DRG P2X3 receptor and SERT in IBS rats. Results:Compared to the model group,the AWR score in the EA group decreased significantly(P<0.05),the resting membrane potential(P<0.05)and the number of action potentials(P<0.05)of DRG neurons reduced,and the baseline intensity increased(P<0.05);additionally,the expression of P2X3 receptor in DRG decreased(P<0.01),and the SERT expression increased(P<0.05).Compared to the P2X3 receptor agonist group,the SERT protein expression in DRG was higher in the EA group.In SERT-/-rats,the P2X3 receptor expression in DRG increased in the EA group compared to the model group(P<0.01). Conclusion:EA modulates the electrophysiological characteristics of intestinal primary sensory neurons by regulating the expression of SERT and P2X3 receptor in DRG of IBS rats.This modulation may contribute to the mechanism by which EA alleviates peripheral sensitization of visceral pain in IBS rats.

[Objective]This study aims to investigate the awareness and educational needs regarding fertility preservation(FP)among healthcare professionals in clinical departments of hospitals at various levels in Southern China.[Methods]An online questionnaire survey was conducted from November 1,2022,to April 1,2024,targeting healthcare professionals in clinical departments from various levels of hospitals in Southwest and South China,including those working at and trained in our hospital.A total of 398 questionnaires were collected.After excluding 14 invalid questionnaires,384 valid responses were analyzed.Data collected included region,gender,age,job title,years of work experience,educational background,awareness of FP and educational needs.An ordinal Logistic regression analysis was performed to identify factors influencing FP awareness among healthcare professionals.[Results]Among the 384 healthcare professionals surveyed,there were 256 physicians and 128 nurses.Approximately 98.96%of the respondents believed that FP is important for family and social health development.Among various FP methods,the awareness rate of egg freezing was the highest,with awareness rates of 98.44%for physicians and 99.22%for nurses.Peer communication was the primary source of FP knowledge for healthcare professionals,with 92.97%of physicians and 89.06%of nurses acquiring FP knowledge through peer communication.Univariate analysis indicated that educational background,department,and work location were significantly associated with FP awareness(P<0.05).Multivariate Logistic regression analysis revealed that profession and department were key influencing factors(P<0.05).[Conclusion]With the promotion of FP in recent years,the awareness of FP among healthcare professionals has improved but remains insufficient.Although the awareness rate of FP among healthcare professionals in this survey is higher than that in previous studies,it is still only 78.13%,especially the wareness rate of ovarian tissue freezing technology is low,with the awareness rates of physicians and nurses being 69.53%and 53.13%,respectively.Appropriate educational strategies and directions should be adopted for different healthcare groups to further enhance their awareness of FP,thereby better serving patients in need.

Objective: To observe the effect of moxibustion on behaviors and related products of tryptophan (Trp) metabolism in the colon of mice with irritable bowel syndrome (IBS), and to explore the mechanism of moxibustion in the IBS treatment.Methods: Twenty-four mice were randomly divided into a normal group, a model group, a moxibustion group, and a probiotic group, with 6 mice in each group. The visceral pain model of IBS was established by enema with 2,4,6-trinitrobenzene sulfonic acid (TNBS) solution. Mice in the moxibustion group were treated with mild moxibustion at bilateral Zusanli (ST36), and those in the probiotic group were treated with probiotics such as Bifidobacterium by gavage. Abdominal withdrawal reflex (AWR) test, elevated plus-maze (EPM) test, and forced swimming test (FST) were performed after treatment. The expression levels of 5-hydroxytryptamine (5-HT) and tryptophan hydroxylase 1 (TPH1) in the colon were detected by immunofluorescence, and the expression levels of Trp, kynurenine (Kyn), and indole-2,3-oxygenase (IDO) in the colon were detected by enzyme-linked immunosorbent assay. Results: Compared with the normal group, the AWR scores were increased significantly in the model group under different pressure values (P<0.01), the open-arm staying time and open-arm entries in the EPM test were decreased significantly (P<0.01, P<0.05), the motionless time in the FST was increased significantly (P<0.01), and the expression levels of colonic Trp, TPH1, IDO, 5-HT, and Kyn were increased significantly (P<0.01) in the models. Compared with the model group, the AWR scores were differently decreased (P<0.05 or P<0.01), the open-arm entries in the EPM test were increased (P<0.05), the motionless times in the FST were decreased (P<0.05), and the colonic expression levels of Trp, TPH1, IDO, and 5-HT were decreased (P<0.01 or P<0.05) in the moxibustion and probiotic groups; the open-arm staying time was significantly increased in the moxibustion group (P<0.01), and the colonic expression level of Kyn was significantly decreased in the probiotic group (P<0.01). Conclusion: Moxibustion at Zusanli (ST36) improves visceral pain and pain mood and down-regulates the expression levels of colonic TPH1, IDO, Trp, 5-HT, and Kyn in IBS mice.

Objective:To systematically assess the efficacy and safety of acupuncture therapy for essential hypertension.Methods:A computerized literature search of the Chinese National Knowledge Infrastructure(CNKI),Chongqing VIP Database(CQVIP),Wanfang Academic Journal Full-text Database(Wanfang),China Biology Medicine Disc(CBM),PubMed,Excerpta Medica Database(EMBASE),and Cochrane Library was conducted to retrieve randomized controlled clinical trials on acupuncture as the main intervention for the treatment of essential hypertension published from the inception of the database to 30 January 2021.The risk-of-bias assessment was carried out for each included study according to the Cochrane Handbook.Data analysis was performed using Review Manager 5.4.1 and Stata 15.0.Results:After the screening,46 randomized controlled trials involving a total of 3 859 subjects were included.Primary outcomes included changes in the diastolic blood pressure after intervention[eight studies showed that the acupuncture plus antihypertensive drug group was better than the antihypertensive drug monotherapy group[mean difference(MD)=1.45,95%confidence interval(CI)(0.48,2.43),P=0.004,fixed effects model;I2=39%]and changes in the systolic blood pressure after intervention{11 studies showed that the acupuncture plus antihypertensive drug group was better than the antihypertensive drug monotherapy group[MD=8.60,95%CI(7.12,10.07),P<0.00001,fixed effects model;I2=26%]}.The secondary outcome was antihypertensive efficacy,12 studies of acupuncture monotherapy group[risk ratio(RR)=1.20,95%CI(1.12,1.28),P<0.00001,fixed effects model;I2=36%]and 15 studies of acupuncture combined with antihypertensive drug group[RR=1.27,95%CI(1.20,1.34),P<0.00001,fixed effects model;I2=6%]showed better results than the antihypertensive drug monotherapy group in antihypertensive efficacy.In terms of the adverse events,four studies showed that the acupuncture monotherapy group had fewer adverse events than the antihypertensive drug monotherapy group[RR=0.10,95%CI(0.04,0.25),P<0.00001,fixed effects model;I2=0%].Conclusion:Acupuncture combined with antihypertensive drugs is superior to antihypertensive drugs alone in reducing blood pressure,and acupuncture therapy is effective and safe for the treatment of essential hypertension with fewer side effects.However,there is still a lack of high-quality multicenter randomized double-blinded controlled trials in this field.Rigorous large-sample clinical trials are needed to validate these findings.

Objective: To compare the efficacy and safety of combining diosmin with Jiuhua hemorrhoid suppository versus diosmin alone for the treatment of hemorrhoid hemorrhage. Methods: The Jiuhua hemorrhoid suppository study was conducted in 10 medical centers across China from April 1, 2019 to June 30, 2020. Patients with hemorrhoid bleeding were randomized in a ratio of 1 : 1 to either receive Jiuhua hemorrhoid suppository and diosmin tablets (the study group) or diosmin tablets alone (the control group). The suppository was used once a day after defecation or at bedtime after rinsing the anus with warm water. Diosmin tablets were administered only once a day (0.9 g). The primary endpoint of the study was the assessment of hemorrhoid bleeding relief 7 ± 2 days after treatment, classified as “very effective” “effective” and “ineffective”. The secondary endpoint included the evaluation of pain alleviation using the visual analogue scale (VAS, with scores ranging from 0 to 10) and edema (with scores ranging from 0 to 3). The safety of the two treatment regimens was evaluated 14 ± 2 days after drug administration. Results: The full analysis set (FAS) comprised 107 participants in the study group and 111 in the control group, while the per-protocol set (PPS) included 106 participants in the study group and 111 in the control group. In terms of hemorrhoid bleeding, the proportion of very effective and effective cases in the study group were significantly higher than that in the control group [106 (99.06%) vs. 91 (81.98%), P < 0.0001] in the FAS, and the PPS results [105 (99.06%) vs. 91 (81.98%), P < 0.0001] were comparable to the FAS results. The pain VAS scores at day 7 after treatment were comparable between the two groups (0.80 ± 1.17 vs. 0.80 ± 1.20, P = 0.2177). The majority of the participants in both groups had an edema score of 0 at day 7 after treatment [96 (89.72%) vs. 99 (91.67%), P = 0.370 5]. Adverse events (AEs) occurred in 9 patients (8.4%) in the study group and 3 patients (2.7%) in the control group. In addition, 5 AEs in the study group and 1 AE in the control group were possibly in association with the study drug. Conclusion Compared with the administration of diosmin oral tablets alone, the addition of Jiuhua hemorrhoid suppository to the tablets demonstrates enhanced efficacy in addressing hemorrhoid bleeding, with satisfactory patient adherence and acceptable safety.

Abnormal iron metabolism mediated by ferritinophagy is one of the most important mechanisms in the occurrence of ferroptosis.The regulatory mechanism of ferritinophagy mainly involves the transcription of NCOA4 and its corresponding protein modifications.Ferroptosis plays an important role in the development of colitis and colitis-associated cancer,and target-oriented regulation of ferroptosis can alleviate colonic inflammatory response and induce the tumor cell death.This article mainly reviewed the regulatory mechanism of NCOA4-mediated ferritinophagy and its progress in colitis and colitis-related cancer,which may provide a new point for the investigation on mechanism of colitis and inflammation-cancer transformation.

OBJECTIVE To investigate the mechanism of Mayuan tongbian zhitong decoction on improving slow-transmission constipation（STC）in rats by regulating AMP activated protein kinase （AMPK）/endothelial nitric oxide synthase （eNOS）signaling pathway. METHODS The rats were randomly divided into blank group ，model group ，Mayuan tongbian zhitong decoction low-dose，medium-dose and high-dose groups （6，12，18 mg/kg），with 10 rats in each group. Except for blank group ，other groups were given Compound diphenoxylate suspension to induce STC model. After modeling ，blank group and model group were given normal saline intragastrically ，and Mayuan tongbian zhitong decoction groups were given relevant medicine intragastrically ， once a day ，for consecutive 2 weeks. The number of feces and water content of feces in each group were observed before and after treatment；the carbon powder propulsion rate of rats in each group was calculated ；the pathological structure of colon in each group was observed ；the levels of nitric oxide （NO）and nitric oxide synthase （NOS）in colon tissues of rats in each group were detected；the expressions of AMPK ，eNOS，mammalian target of rapamycin （mTOR），tuberous sclerosis complex 1（Tsc-1）， Tsc-2 and eukaryotic promoter 4E binding protein （4ebp）were also detected. The active ingredients of Cannabis sativa ，Citrus aurantium and Rehmannia glutinosa were screened from Mayuan tongbian zhitong decoction. The active ingredients with high Degree value were docked with AMPK and eNOS ，to verify the interaction. RESULTS Compared with before treatment ，the number and water content of feces were increased significantly in Mayuan tongbian zhitong decoction groups （P＜0.05）. Compared with blank group ，carbon powder propulsion rate of model group was decreased significantly （P＜0.05）； colonic structure was disordered ，and a large number of inflammatory cells were seen in submucosa ；the levels of NO and NOS in colon tissue as well as the protein expressions of AMPK ，eNOS，mTOR，Tsc-1，Tsc-2 and 4ebp were increased significantly （P＜0.05）. Compared with model group ，above indexes of Mayuan tongbian zhitong decoction groups （except for NOS in low-dose group ）were reserved significantly （P＜0.05）. In the molecular docking experiment ，the active components with the highest Degree values in C. sativa ，C. aurantium and R. glutinosa were（Z）-3-（4-hydroxy-3-methoxy-phenyl）-N-[2-（4-hydroxyphenyl）ethyl] acrylamide，nobiletin and stigmasterol. The binding energies of AMPK with these three components were －5.15，－4.61 and －4.83 kJ/mol，the binding energies of eNOS with these three components were －6.11，－5.40 and －5.91 kJ/mol. The conformations of these three compounds with AMPK and eNOS were stable and their binding activities were high. CONCLUSIONS Mayuan tongbian zhitong decoction can improve the constipation symptoms and intestinal function in STC model rats ，and its specific mechanism may be related to the inhibition of AMPK/eNOS signaling pathway.
