The aim of our study was to update data on anal diseases. Non-specific, it can reveal an emergency, a serious illness, a chronic disease or a benign condition. It was a prospective, descriptive and analytical study from April 2022 to March 2023, carried out in the hepato-gastroenterology unit of the Centre de Santé de Référence de la commune V du District de Bamako in Mali. Out of seven hundred and forty-nine (749) patients seen in consultation, 98 had anal pathology, i.e. a prevalence of 13.08%. The mean age was 40 ± 15.15 years and the sex ratio was 1.5. Hemorrhoidal disease and anal fissure were the most frequent pathologies in 66.4% and 24.4% of cases respectively. Medical treatment was initiated in 91.9% of patients with hemorrhoidal disease and 91.7% with anal fissure. Anal pathologies are common in young male patients. In our context, they are dominated by benign conditions.展开更多

Serotonin is a monoamine neurotransmitter. Numerous studies have reported the association between the serotonin receptor family (5-HTR) gene polymorphisms and ADHD, but the results are still controversial. In this study, we conducted a meta-analysis of the association between 5-HTRIB, 5-HTR2A, and 5-HTR2C genetic variants and ADHD. The results showed that the 861G allele of 5-HTRIB SNP rs6296 could significantly increase the risk of ADHD (OR= 1.09, 95% CI: 1.01-1.18); the 5-HTR2C gene rs518147 (OR=1.69, 95% CI: 1.38-2.07) and rs3813929 (OR = 1.57, 95% CI: 1.25-1.97) were all associated with the risk of ADHD. In addition, we also carried on a case- control study to explore the relevance between potential candidate genes 5-HTR1A, 5-HTRIE, 5-HTR3A and ADHD. The results indicated that 5-HTRIA rs6295 genotype (CC+CG vs. GG OR=Z00, 95% CI: 1.23-3.27) and allele (OR=1.77, 95% CI: 1.16-2.72) models were statistically significantly different between case group and control group. This study is the first comprehensive exploration and summary of the association between serotonin receptor family genetic variations and ADHD, and it also provides more evidence for the etiology of ADHD.展开更多

文摘Broody behavior is regulated by hypothalamic prolactin secretion,which seriously affects egg production in poulty production.Numerous studies have provided evidence that animal behavior is governed by dynamic bidirectional communication between specific gut bacteria and their host via the brain-gut-microbiome axis.However,little research focused on how the gut microbiota influence broody behavior in poultry.In this study,Zhedong white geese in laying and brooding phases were selected.Ten differentially abundant bacteria in cecum were detected between brooding and laying geese through metagenomic analyses and 16S rRNA sequencing(P<0.05),and Bacteroides fragilis was specifically identified as a key driver species in the brooding geese.Moverover,the serum metabolites were quantified,and the 313 differentially abundant metabolites were found between the two groups of different physiological geese.They were primarily enriched in the tryptophan metabolism pathways.Pearson correlation analyses revealed there was a significant positive correlation between B.fragilis abundance and the context of 11 tryptophan metabolism-related metabolites(such as serotonin,etc.)in broody geese,which hinted that those tryptophan metabolites might be produced or driven by B.fragilis.Finally,the serum hormone levels were also measured.We found there was a positive correlation between B.fragilis abundance and content of serotonin.Besides,prolactin secreted by the pituitary gland was greater in brooding geese than that in laying geese,which was also highly correlated with B.fragilis abundance.This result implied that B.fragilis could promote the secretion of prolactin by the pituitary gland.Together,the current study findings provided the information on gut microbiota influencing broody behavior,B.fragilis produced or driven more serum serotonin,and stimulated the pituitary gland to secret more prolactin,which potentially offered a new enlightenment for the intervention of broody behavior in poultry.
文摘Anal pathologies are conditions affecting the anal margin and the anal canal. The aim of our study was to update data on anal diseases. Non-specific, it can reveal an emergency, a serious illness, a chronic disease or a benign condition. It was a prospective, descriptive and analytical study from April 2022 to March 2023, carried out in the hepato-gastroenterology unit of the Centre de Santé de Référence de la commune V du District de Bamako in Mali. Out of seven hundred and forty-nine (749) patients seen in consultation, 98 had anal pathology, i.e. a prevalence of 13.08%. The mean age was 40 ± 15.15 years and the sex ratio was 1.5. Hemorrhoidal disease and anal fissure were the most frequent pathologies in 66.4% and 24.4% of cases respectively. Medical treatment was initiated in 91.9% of patients with hemorrhoidal disease and 91.7% with anal fissure. Anal pathologies are common in young male patients. In our context, they are dominated by benign conditions.
文摘The perianal disease affects up to one-third of individuals with Crohn's disease(CD),causing disabling symptoms and significant impairment in quality of life,particularly for those with perianal fistulising CD(PFCD).The collaborative effort between gastroenterologists and surgeons is essential for addressing PFCD to achieve fistula closure and promote luminal healing.Limited fistula healing rates with conventional therapies have prompted the emergence of new biological agents,endoscopic procedures and surgical techniques that show promising results.Among these,mesenchymal stem cells injection is a particularly hopeful therapy.In addition to the burden of fistulas,individuals with perianal CD may face an increased risk of developing anal cancer.This underscores the importance of surveillance programmes and timely interventions to prevent late diagnoses and poor outcomes.Currently,there is no established formal anal screening programme.In this review,we provide an overview of the current state of the art in managing PFCD,including novel medical,endoscopic and surgical approaches.The discussion also focuses on the relevance of establishing an anal cancer screening programme in CD,intending to propose a risk-based surveillance algorithm.The validation of this surveillance programme would be a significant step forward in improving patient care and outcomes.
文摘Serotonin syndrome(SS)is a drug-induced clinical syndrome resulting from increased serotonergic activity in the central nervous system.Although more than seven decades have passed since the first description of SS,it is still an enigma in terms of terminology,clinical features,etiology,pathophysiology,diagnostic criteria,and therapeutic measures.The majority of SS cases have previously been reported by toxicology or psychiatry centers,particularly in people with mental illness.However,serotonergic medications are used for a variety of conditions other than mental illness.Serotonergic properties have been discovered in several new drugs,including over-the-counter medications.These days,cases are reported in non-toxicology centers,such as perioperative settings,neurology clinics,cardiology settings,gynecology settings,and pediatric clinics.Overdoses or poisonings of serotonergic agents constituted the majority of the cases observed in toxicology or psychiatry centers.Overdose or poisoning of serotonergic drugs is uncommon in other clinical settings.Patients may develop SS at therapeutic dosages.Moreover,these patients may continue to use serotonergic medications even if they develop mild to moderate SS due to several reasons.Thus,the clinical presentation(onset,severity,and clinical features)in such instances may not exactly match what toxicologists or psychiatrists observe in their respective settings.They produce considerable diversity in many aspects of SS.However,other experts discount these new developments in SS.Since SS is a potentially lethal illness,consensus is required on several concerns related to SS.
文摘Anal pruritus is a common anorectal symptom that can significantly impair a patient’s quality of life,including their mental health.It can be one of the most difficult proctological conditions to treat.Patients often delay seeking medical attention,since it is an embarrassing but non-life-threatening situation.Pruritus ani can be associated with idiopathic and secondary causes,such as anorectal diseases,cancer(anal or colorectal),dermatological and sexually transmitted diseases,fungal infections and systemic diseases.If patients are referred for a colonoscopy,this can sometimes provide the first opportunity to evaluate the perianal area.Classifications of anal pruritus are based on the abnormalities of the perianal skin,one of the most commonly used being the Washington classi-fication.A proper digital anorectal examination is important,as well as an anoscopy to help to exclude anorectal diseases or suspicious masses.Endoscopists should be aware of the common etiologies,and classification of the perianal area abnormalities should be provided in the colonoscopy report.Information on treatment possibilities and follow-up can also be provided.The treatment normally consists of a triple approach:proper hygiene,elimination of irritants,and skin care and protection.Several topical therapies have been described as possible treatments,including steroids,capsaicin,tacrolimus and methylene blue intradermal injections.

文摘BACKGROUND Serotonin receptor 2B(5-HT2B receptor)plays a critical role in many chronic pain conditions.The possible involvement of the 5-HT2B receptor in the altered gut sensation of irritable bowel syndrome with diarrhea(IBS-D)was investigated in the present study.AIM To investigate the possible involvement of 5-HT2B receptor in the altered gut sensation in rat model and patients with IBS-D.METHODS Rectosigmoid biopsies were collected from 18 patients with IBS-D and 10 patients with irritable bowel syndrome with constipation who fulfilled the Rome IV criteria and 15 healthy controls.The expression level of the 5-HT2B receptor in colon tissue was measured using an enzyme-linked immunosorbent assay and correlated with abdominal pain scores.The IBS-D rat model was induced by intracolonic instillation of acetic acid and wrap restraint.Alterations in visceral sensitivity and 5-HT2B receptor and transient receptor potential vanilloid type 1(TRPV1)expression were examined following 5-HT2B receptor antagonist adminis-tration.Changes in visceral sensitivity after administration of the TRPV1 antago-INTRODUCTION Irritable bowel syndrome(IBS)is a chronic functional bowel disorder characterized by recurrent abdominal pain with altered bowel habits that affects approximately 15%of the population worldwide[1].IBS significantly impacts the quality of life of patients.Although the pathogenesis of IBS is not completely understood,the role of abnormal visceral sensitivity in IBS has recently emerged[2,3].5-Hydroxytryptamine(5-HT)is known to play a key role in the physiological states of the gastrointestinal tract.Plasma 5-HT levels in IBS with diarrhea(IBS-D)patients were greater than those in healthy controls[4],suggesting a possible role of 5-HT in the pathogenesis of IBS-D.The serotonin receptor 2(5-HT2 receptor)family comprises three subtypes:5-HT2A,5-HT2B,and 5-HT2c.All 5-HT2 receptors exhibit 46%-50%overall sequence identity,and all of these receptors preferentially bind to Gq/11 to increase inositol phosphates and intracellular calcium mobilization[5].5-HT2B receptors are widely expressed throughout the gut,and experimental evidence suggests that the primary function of 5-HT2B receptors is to mediate contractile responses to 5-HT through its action on smooth muscle[6].The 5-HT2B receptor is localized to both neurons of the myenteric nerve plexus and smooth muscle in the human colon.The 5-HT2B receptor mediates 5-HT-evoked contraction of longitudinal smooth muscle[6].These findings suggest that the 5-HT2B receptor could play an important role in modulating colonic motility,which could affect sensory signaling in the gut.Other laboratories have shown that the 5-HT2B receptor participates in the development of mechanical and formalin-induced hyperalgesia[7,8].A 5-HT2B receptor antagonist reduced 2,4,6-trinitrobenzene sulfonic acid(TNBS)and stress-induced visceral hyperalgesia in rats[9,10].However,the role of the 5-HT2B receptor in IBS-D patients and in acetic acid-and wrap restraint-induced IBS-D rat models was not investigated.

文摘Objective:To compare the efficacy of anal adenectomy with virtual hanging wire and anal fistulotomy in the treatment of low anal fistula in infants and children.Methods:60 children with low anal fistula who were admitted to our hospital from October 2021 to March 2022 and met the inclusion criteria were randomly divided into two groups of 30 cases each;the treatment group was treated with anal adenectomy and virtual hanging wire surgery,and the control group was treated with anal fistula resection.The clinical efficacy after treatment was compared.Results:The total effective rate of both groups was 96.67%and the difference between the two groups was not statistically significant(P>0.05).The postoperative pain score of the treatment group was lower than that of the control group(P<0.05).The length of hospitalization and healing time of the treatment group was lower than that of the control group(P<0.05).The anal function of the patients in both groups was normal,and there was no adverse reaction.Conclusion:Anal gland excision and virtual hanging surgery for the treatment of low anal fistula in infants and children have the advantages of mild pain,reduced length of hospitalization,short healing time,and better patient experience as compared to anal fistula excision.
文摘Background:Anal fistula is a long-term disease characterized by a tubular structure with one end opening in the anorectal canal and the other end opening on the surface of the perineum or perianal skin with chronic pus drainage.It is linked to Bhagandar in Ayurveda,and in Sushruta Samhita,Acharya has mentioned 5 forms of Bhagandar.The boil in the present case was Shukla,sthira i.e.hard and firm,with Picchila strava and Kandu resembling the features of Parisraavi bhagandar.Aim and objective:The current case was diagnosed as Parisravi bhagandar,which resembles trans-sphincteric or intersphincteric fistula in modern ano.In Ayurveda,the management of Parisraavi Bhagandar,Shastra,kshara,and Agnikarma is advised and the use of Ksharasutra,which contributes to complete cutting and healing of the track without reoccurrence,similarly Modern surgeon depends on surgery i.e radical excision of the track,ligation with Seton,and use of chemical irritants like urethane,silver nitrates,etc.A cutting seton(tight)gently slices the confined muscle to close the fistula with the least interruption to continence.This operation is especially advised when a one-stage fistulotomy poses a considerable risk of incontinence.Material and methods:The method performed here was Core Partial Fistulectomy followed by Ksharasutra application till complete healing of the wound.Discussion and conclusion:This case study provides the successful management of Parisraavi Bhagandara(high anal,trans-sphincteric fistula in ano)in 61-year-old male patient with an integrated surgical&Ayurvedic management approach.
文摘Attention deficit hyperactivity disorder (ADHD) is one of the most common mental disorders in childhood, with a high heritability about 60% to 90%. Serotonin is a monoamine neurotransmitter. Numerous studies have reported the association between the serotonin receptor family (5-HTR) gene polymorphisms and ADHD, but the results are still controversial. In this study, we conducted a meta-analysis of the association between 5-HTRIB, 5-HTR2A, and 5-HTR2C genetic variants and ADHD. The results showed that the 861G allele of 5-HTRIB SNP rs6296 could significantly increase the risk of ADHD (OR= 1.09, 95% CI: 1.01-1.18); the 5-HTR2C gene rs518147 (OR=1.69, 95% CI: 1.38-2.07) and rs3813929 (OR = 1.57, 95% CI: 1.25-1.97) were all associated with the risk of ADHD. In addition, we also carried on a case- control study to explore the relevance between potential candidate genes 5-HTR1A, 5-HTRIE, 5-HTR3A and ADHD. The results indicated that 5-HTRIA rs6295 genotype (CC+CG vs. GG OR=Z00, 95% CI: 1.23-3.27) and allele (OR=1.77, 95% CI: 1.16-2.72) models were statistically significantly different between case group and control group. This study is the first comprehensive exploration and summary of the association between serotonin receptor family genetic variations and ADHD, and it also provides more evidence for the etiology of ADHD.

文摘Background Serotonin is an important signaling molecule that regulates secretory and sensory functions in the gut.Gut microbiota has been demonstrated to affect serotonin synthesis in rodent models.However,how gut microbes regulate intestinal serotonin production in piglets remains vague.To investigate the relationship between microbiota and serotonin specifically in the colon,microbial composition and serotonin concentration were analyzed in ileum-cannulated piglets subjected to antibiotic infusion from the ileum when comparing with saline infusion.Microbes that correlated positively with serotonin production were isolated from piglet colon and were further used to investi-gate the regulation mechanisms on serotonin production in IPEC-J2 and a putative enterochromaffin cell line RIN-14B cells.Results Antibiotic infusion increased quantities of Lactobacillus amylovorus(LA)that positively correlated with increased serotonin concentrations in the colon,while no effects observed for Limosilactobacillus reuteri(LR).To understand how microbes regulate serotonin,representative strains of LA,LR,and Streptococcus alactolyticus(SA,enriched in feces from prior observation)were selected for cell culture studies.Compared to the control group,LA,LR and SA supernatants significantly up-regulated tryptophan hydroxylase 1(TPH1)expression and promoted serotonin production in IPEC-J2 cells,while in RIN-14B cells only LA exerted similar action.To investigate potential mechanisms mediated by microbe-derived molecules,microbial metabolites including lactate,acetate,glutamine,andγ-aminobutyric acid were selected for cell treatment based on computational and metabolite profiling in bacte-rial supernatant.Among these metabolites,acetate upregulated the expression of free fatty acid receptor 3 and TPH1 while downregulated indoleamine 2,3-dioxygenase 1.Similar effects were also recapitulated when treating the cells with AR420626,an agonist targeting free fatty acid receptor 3.Conclusions Overall,these results suggest that Lactobacillus amylovorus showed a positive correlation with sero-tonin production in the pig gut and exhibited a remarkable ability to regulate serotonin production in cell cultures.These findings provide evidence that microbial metabolites mediate the dialogue between microbes and host,which reveals a potential approach using microbial manipulation to regulate intestinal serotonin biosynthesis.

文摘In animals,serotonin is a neurotransmitter and mood regulator.In plants,serotonin functions in energy acquisition,tissue maintenance,delay of senescence,and response to biotic and abiotic stresses.In this study,we examined the effect of serotonin enrichment of rice endosperm on plant growth,endosperm development,and grain quality.To do so,TDCs and T5H were selected as targets for serotonin fortification.Overexpression of TDC1 or TDC3 increased serotonin accumulation relative to overexpression of T5H in rice grain.Transgenic lines of target genes driven by the Gt1 promoter showed better field performance than those driven by the Ubi promoter.Overexpression of T5H showed little effect on plant growth or grain physicochemical quality.In neuronal cell culture assays,serotonin induced neuroprotective action against apoptosis.Breeding of rice cultivars with high serotonin content may be beneficial for health and nutrition.

文摘[Objectives]To explore the curative effect of Self-made Wubeizi Decoction combined with recombinant human acidic fibroblast growth factor(rhaFGF)in promoting postoperative wound healing in patients with anal fistula.[Methods]A total of 82 patients with anal fistula who underwent anal fistula resection+use of setons in Luodian Hospital during January and March of 2020 were randomly divided into observation group and control group with 41 cases in each group.The control group was given rhaFGF external application regimen,and the observation group was treated with Self-made Wubeizi Decoction on the basis of the control group.After 3 weeks of treatment,the differences in curative effects of TCM syndromes were compared between the two groups.Besides,the changes in TCM symptom scores,inflammatory mediators[interleukin-12(IL-12),tumor necrosis factor-α(TNF-α),interferon-γ(IFN-γ)],anorectal functions[anal resting pressure(ARP),maximal systolic pressure(MSP)and maximum tolerated volume(MTV)of the anal canal],quality of life[GQOLI-74 scores]were compared.[Results]After 3 weeks of treatment,the total effective rate of the observation group was significantly higher than that of the control group(P<0.05);the levels of TCM symptom scores,IL-12,TNF-α,IFN-γ,ARP,MSP,and MTV in both groups were significantly lower than those before treatment,and these levels in the observation group was significantly lower than that in the control group at the same time(P<0.05).The GQOLI-74 scores of both groups were significantly higher than those before treatment,and the observation group was significantly higher than the control group(P<0.05).[Conclusions]The Self-made Wubeizi Decoction combined with rhaFGF therapy has a significant effect in promoting postoperative wound healing in patients with anal fistula.It can effectively inhibit the local inflammation of patients,facilitate the recovery of anorectal function and improve the quality of life,thus has high clinical application value.
文摘BACKGROUND The incidence of anal cancer has been increasing in the United States.Smoking is a well-established risk factor;however,the impact of smoking on disease recurrence and outcome has not been well studied.The aim of this study was to assess the association between anal cancer recurrence and cigarette smoking.AIM To investigate the relationship between cigarette smoking status and anal cancer treatment outcome.METHODS The cancer registry from a single,community hospital was screened for patients with anal cancer between 2010 and 2021.The following characteristics were gathered from the database:Age;sex;cigarette smoking history;American Joint Committee on Cancer Clinical Stage Group;response to therapy;recurrence;time to recurrence;mortality;time to death;and length of follow-up.Patients were divided into the following groups:Current smokers;former smokers;and never smokers.SPSSv25.0 software(IBM Corp.,Armonk,NY,United States)was used for statistical analysis.RESULTS A total of 95 patients from the database met the screening criteria.There were 37 never smokers,22 former smokers,and 36 current smokers.There was no difference between groups in regards to race or sex.There was no difference in the American Joint Committee on Cancer Clinical Stage Group between groups.The former smokers were significantly older when compared to never smokers and current smokers(66.5±13.17 vs 57.4±7.82 vs 63.7±13.80,P=0.011).Former smokers and current smokers had a higher recurrence rate compared to never smokers(30.8%and 20.8%compared to zero,P=0.009).There was not a significant difference in recurrence between former smokers and current smokers.There was no difference in the mortality,non-response rate,or time to death between the groups.CONCLUSION Our data contributes evidence that cigarette smoking status is associated with increased recurrence for patients with anal cancer.
文摘Background:Agnimandya,the underlying cause of anorectal disorders,of which Parikartika is the most well-known,is brought on by lifestyles characterized by sedentary behavior,elevated stress,poor nutrition,and sleep habits.The illness known as Parikartika,with signs and symptoms like fissure-in-ano in modern sources,is characterized by kartanvat Vedana(cutting pain)over the anal region.Acute fissure-in-ano is treated with analgesics,stool softeners,and soothing creams.Treatment options for hazy chronic fissures include anal dilatation,sphincterotomy,fissurectomy,and anal advancement flap.In addition to using laxatives and substances that promote wound healing(vranaropaka),the concepts of management of Parikartika in Ayurveda are more heavily weighted towards enhancing the nature,character,and consistency of stool and stabilizing the digestive functions Parikartika is mentioned in Ayurvedic texts as a complication of many Ayurvedic procedures,such as Vamana,Virechana,and Basti,as well as a complication of some disorders,such as Arsh,Atisar,and Grahani.Aim and objective:This article aims to comprehensively review the literature,diagnostic,and therapeutic aspects of Parikartika,with its correlation to Fissure in ano,and compare the clinical outcomes of the treatment modalities with supporting references,consolidating all pertinent information on the subject.Material&method:Collection from Samhita’s,commentaries,exploring medical websites,Ayurvedic journals related to the topic of Parikartika and fissure in ano,systematic record of the collected literature and a summary of each item.Organize the collected materials,reference and citation are the material and method followed here.Discussion&conclusion:This is an extensive literature review on Parikartika in Ayurveda,exploring its contemporary association with Fissure in Ano.The research offers insights that can inform the evaluation and treatment of this condition,considering both conservative and surgical approaches,thereby enhancing clinical management strategies.
文摘BACKGROUND Perianal fistulising Crohn's disease(PFCD)and glandular anal fistula have many similarities on conventional magnetic resonance imaging.However,many patients with PFCD show concomitant active proctitis,but only few patients with glandular anal fistula have active proctitis.AIM To explore the value of differential diagnosis of PFCD and glandular anal fistula by comparing the textural feature parameters of the rectum and anal canal in fat suppression T2-weighted imaging(FS-T2WI).METHODS Patients with rectal water sac implantation were screened from the first part of this study(48 patients with PFCD and 22 patients with glandular anal fistula).Open-source software ITK-SNAP(Version 3.6.0,http://www.itksnap.org/)was used to delineate the region of interest(ROI)of the entire rectum and anal canal wall on every axial section,and then the ROIs were input in the Analysis Kit software(version V3.0.0.R,GE Healthcare)to calculate the textural feature parameters.Textural feature parameter differences of the rectum and anal canal wall between the PFCD group vs the glandular anal fistula group were analyzed using Mann-Whitney U test.The redundant textural parameters were screened by bivariate Spearman correlation analysis,and binary logistic regression analysis was used to establish the model of textural feature parameters.Finally,diagnostic accuracy was assessed by receiver operating characteristic-area under the curve(AUC)analysis.RESULTS In all,385 textural parameters were obtained,including 37 parameters with statistically significant differences between the PFCD and glandular anal fistula groups.Then,16 texture feature parameters remained after bivariate Spearman correlation analysis,including one histogram parameter(Histogram energy);four grey level co-occurrence matrix(GLCM)parameters(GLCM energy_all direction_offset1_SD,GLCM entropy_all direction_offset4_SD,GLCM entropy_all direction_offset7_SD,and Haralick correlation_all direction_offset7_SD);four texture parameters(Correlation_all direction_offset1_SD,cluster prominence_angle 90_offset4,Inertia_all direction_offset7_SD,and cluster shade_angle 45_offset7);five grey level run-length matrix parameters(grey level nonuniformity_angle 90_offset1,grey level nonuniformity_all direction_offset4_SD,long run high grey level emphasis_all direction_offset1_SD,long run emphasis_all direction_offset4_SD,and long run high grey level emphasis_all direction_offset4_SD);and two form factor parameters(surface area and maximum 3D diameter).The AUC,sensitivity,and specificity of the model of textural feature parameters were 0.917,85.42%,and 86.36%,respectively.CONCLUSION The model of textural feature parameters showed good diagnostic performance for PFCD.The texture feature parameters of the rectum and anal canal in FS-T2WI are helpful to distinguish PFCD from glandular anal fistula.

文摘With the change of people’s lifestyle and diet,the incidence of anorectal diseases is increasing year by year.Anal fistula is a common anorectal disease.Because it cannot heal by itself,surgery has become the main treatment method.Due to the particularity of wound location and physiological structure,the wound is easily contaminated by bacteria,so dressing change after surgery plays a decisive role in wound healing.Modern western medicine and traditional Chinese medicine have different dressing changing methods respectively.In this paper,we reviewed commonly used dressing changing methods of traditional Chinese and western medicine after anal fistula surgery.
文摘Objective:To explore the therapeutic effect of integrated traditional Chinese and western medicine on anal pruritus after anorectal surgery.Methods:Ninety-eight patients with anal pruritus after anorectal surgery in our hospital were selected as the research subjects.They were divided into two groups,the control group(50 cases)and the study group(48 cases),according to the treatment plan.The control group was under a simple western medicine treatment plan,while the study group was under an integrated traditional Chinese and western medicine treatment plan.The overall efficacy,severity of anal pruritus,time to eliminate clinical symptoms,and anxiety and depression scores of the two groups of patients under different treatment plans were compared.Results:After two weeks of treatment,the total effective rate of the study group was 95.83%,which was significantly higher than that of the control group(82.00%,P<0.05).After 7 and 14 days of treatment,the anal pruritus scores improved significantly in both the groups,but the study group was superior to the control group,with statistical difference(P<0.01).The time of disappearance of skin itching and skin damage in the study group was shorter than that in the control group.After 14 days of treatment,the anxiety and depression scores of both groups were lower than those after 7 days of treatment;however,there was statistical difference between the two groups(P<0.01).Conclusion:In the clinical treatment of anorectal postoperative diseases,such as anal pruritus,the combination of traditional Chinese and western medicine can significantly improve the symptoms of pruritus,shorten the time of disappearance of clinical symptoms,improve depression and anxiety,and create a positive clinical application value in promoting the rehabilitation of patients and improving their quality of life.
