OBJECTIVES: To observe the effects of moxibustion on colonic mast cell degranulation and inflammatory factor expression in rats with diarrhea-predominant irritable bowel syndrome (IBS-D), and explore the potential mechanism of moxibustion in treating IBS-D. METHODS: Forty-five rat pups born from 5 healthy SPF-grade pregnant SD rats, with 8 rats were randomly selected as the normal group. The remaining 37 rats were intervened with maternal separation, acetic acid enema, and chronic restraint stress to establish the IBS-D model. The successfully modeled 32 rats were then randomly assigned to a model group, a ketotifen group, a moxibustion group, and a moxibustion-medication group, with 8 rats in each group. The rats in the ketotifen group were intervened with intragastric administration of ketotifen solution (10 mL/kg); the rats in the moxibustion group were intervened with suspended moxibustion on bilateral "Tianshu" (ST 25) and "Shangjuxu" (ST 37); the rats in the moxibustion-medication group were intervened with suspended moxibustion combined with intragastric administration of ketotifen solution. All interventions were administered once daily for 7 consecutive days. The diarrhea rate and minimum volume threshold of abdominal withdrawal reflex (AWR) were calculated before and after modeling, as well as after intervention. After intervention, colonic tissue morphology was observed using HE staining; colonic mucosal ultrastructure was examined by scanning electron microscopy; colonic mast cell ultrastructure was observed using transmission electron microscopy; mast cell degranulation was assessed by toluidine blue staining; serum and colonic levels of histamine, interleukin (IL)-1ß, IL-6, IL-1α, trypsin-like enzyme, and protease-activated receptor 2 (PAR-2) were measured by ELISA; the Western blot and real-time quantitative PCR were employed to evaluate the protein and mRNA expression of colonic IL-1ß, IL-6, IL-1α, trypsin-like enzyme, and PAR-2; the immunofluorescence was used to detect the positive expression of histamine, IL-1ß, IL-6, IL-1α, trypsin-like enzyme, and PAR-2 in the colonic tissue. RESULTS: Compared to the normal group, the rats in the model group exhibited extensive infiltration of inflammatory cells in colonic tissue, severe damage to the colonic mucosa, disordered arrangement of villi, reduced electron density, and a significant decrease in granule quantity within mast cells. The diarrhea rate and mast cell degranulation rate were increased (P<0.01), AWR minimum volume threshold was decreased (P<0.01); the serum and colonic levels of histamine, IL-1ß, IL-6, IL-1α, trypsin-like enzyme, and PAR-2 were elevated (P<0.01); the positive expression of histamine, as well as protein, mRNA and positive expression of IL-1ß, IL-6, IL-1α, trypsin-like enzyme, and PAR-2 in the colon were all elevated (P<0.01). Compared to the model group, the rats in the ketotifen group, the moxibustion group, and the moxibustion-medication group exhibited significantly reduced infiltration of inflammatory cells in colonic tissue, relatively intact colonic mucosa, orderly arranged villi, increased electron density, and an augmented number of mast cell granules; the diarrhea rate and mast cell degranulation rate were decreased (P<0.01), and AWR minimum volume threshold was increased (P<0.01); the serum and colonic levels of histamine, IL-1ß, IL-6, IL-1α, trypsin-like enzyme, and PAR-2 were reduced (P<0.01); the positive expression of histamine, as well as protein, mRNA and positive expression of IL-1ß, IL-6, IL-1α, trypsin-like enzyme, and PAR-2 in the colon were all decreased (P<0.01). Compared to the ketotifen group, the moxibustion group showed decreased serum levels of histamine, IL-6, and trypsin-like enzyme (P<0.01, P<0.05), as well as reduced colonic levels of IL-1ß and IL-6 (P<0.01, P<0.05); the protein expression of colonic IL-1ß, IL-1α, and PAR-2 was reduced (P<0.05), and the positive expression of colonic IL-1ß and trypsin-like enzyme was reduced (P<0.01, P<0.05). Compared to both the ketotifen group and the moxibustion group, the moxibustion-medication group exhibited decreased diarrhea rate and mast cell degranulation rate (P<0.01), an increased AWR minimum volume threshold (P<0.01), reduced serum and colonic levels of histamine, IL-1ß, IL-6, IL-1α, trypsin-like enzyme, and PAR-2 (P<0.01), decreased protein expression of colonic IL-1ß, trypsin-like enzyme, and PAR-2 (P<0.01, P<0.05), reduced mRNA and positive expression of colonic IL-1ß, IL-6, IL-1α, trypsin-like enzyme, and PAR-2 (P<0.01, P<0.05), and decreased positive expression of colonic histamine (P<0.01). CONCLUSIONS: Moxibustion on "Tianshu" (ST 25) and "Shangjuxu" (ST 37) might inhibit low-grade inflammatory reactions in the colon of IBS-D model rats. The mechanism may be related to the inhibition of histamine and trypsin-like enzyme secreted by mast cell, thereby reducing the expression of related inflammatory factors.

Clinical, Functional, and Nutritional Efficacy of a Glutamine-Enriched Oligomeric Diet in Patients with Rectal Cancer.

AIMS: This work aims to evaluate the efficacy of nutritional supplementation with a glutamine-enriched oligomeric diet (GEOD) compared to a standard polymeric diet (SPD) in terms of oncology treatment-related diarrhea (OTRD) (frequency and consistency of stools), gastrointestinal toxicity, and functional and nutritional progress. METHODS: This prospective cohort study compared two groups of patients with rectal cancer in treatment with neoadjuvant chemotherapy and radiotherapy who were at risk of malnutrition. Patients were randomized to receive either 400 ml of GEOD or of SPD from the start of radiotherapy to 30 days after its completion. RESULTS: Eighty patients were recruited, 40 per arm. The GEOD arm had improved stool consistency and a greater reduction in the number of stools compared to the SPD arm (p < 0.001). The relative risk (RR) of developing diarrhea in the GEOD arm was 0.059 (95% CI 0.015-0.229). There was a reduced risk of developing intestinal mucositis in the GEOD arm compared to the SPD arm [RR 0.202 (95% CI 0.102 - 0.399)]. The GEOD arm had greater improvements in functional and nutritional status (p < 0.001). CONCLUSIONS: GEOD had a protective effect in terms of the development of gastrointestinal toxicity associated with chemotherapy and radiotherapy treatment in patients with rectal cancer.

Efficacy of different courses of acupuncture for diarrhea irritable bowel syndrome: A protocol for systematic review and meta-analysis.

Irritable Bowel Syndrome (IBS) is the most common functional gastrointestinal disorder. As one of the most common subtypes of IBS, IBS-D can impair the patients' quality of life (QOL) and decreased work productivity. Acupuncture may be a potential treatment for patients with IBS-D. However, the treatment course of acupuncture was diverse. It is unclear what is the optimal acupuncture treatment courses for acupuncture. The efficacy and safety of different courses of acupuncture for IBS-D have not been systematically evaluated yet. The purpose of this study is to evaluate effectiveness of Acupuncture of different courses in the treatment of IBS-D and provide sufficient evidence for clinical recommendations for IBS-D. We will follow the Preferred reporting items for systematic reviews and meta-analysis protocols (PRISMA-P) guidelines to design the protocol of a systematic review and meta-analysis. This systematic review is registered in PROSPERO (CRD42023418846). We will include randomized controlled trials (RCTs) in which the efficacy of Acupuncture is compared with a placebo, sham acupuncture or Pinaverium bromide in the treatment of IBS-D with no language restrictions. The outcomes of interest will be efficiency rate and the Symptoms Severity Score. RCTs will be searched in the electronic database and Clinical Trials Registry Platform from inception to April 2023. Two independent reviewers will independently select studies, extract data from the included studies, and assess the risk of bias using the Cochrane tool. We will choose a random or fixed-effects model based on the heterogeneity index. We will use the relative risk and mean difference to estimate data with 95% CI. A stratified meta-analysis was conducted to evaluate the effect of different treatment courses of Acupuncture: 2weeks, 4weeks(or 1 months), 6 weeks, and 8 weeks. If there is significant clinical and methodological heterogeneity, we will look for the reason for heterogeneity and perform a subgroup analysis. According to the Grading of Recommendations Assessment, Development and Evaluation (GRADE), we will evaluate the evidence quality and provide the recommendation's strength.

Determinants of pneumonia among under-five children at Hiwot Fana specialized hospital, Eastern Ethiopia: unmatched case-control study.

BACKGROUND: Globally, pneumonia is a serious public health issue. Clear evidence is necessary for the early detection and treatment of pneumonia's causes. Yet, there is limited data on this issue in the current study area. Thus, this study aimed to pinpoint the determinants of pneumonia among under-five children at Hiwot Fana Specialized Hospital, Eastern Ethiopia. METHODS: A hospital-based unmatched case-control study was conducted among a sample of 348 (116 cases and 232 controls) children at Hiwot Fana Specialized Hospital from October 1 to November 30, 2022. A consecutive sampling technique was employed, and data were collected with a pre-tested interviewer-administered questionnaire. The data was entered into Epi-Data version 3.1 and analyzed using SPSS version 25 software. Bivariate and multivariate binary logistic regression analyses were fitted. Variables with a 95% confidence interval having a p-value < 0.05 were considered statistically significant. RESULTS: An overall total of 347 (115 cases and 232 controls) among under-five children was included in this study. Factors such as hand washing before child feeding [AOR: 3.11 (1.74-5.57)], birth to 6 months breastfeeding [AOR: 2.76 (1.35-5.25)], zinc supplementation [AOR: 2.5 (1.33-4.40)], diarrhea in the last 2 weeks [AOR: 4.7 (2.64-8.33)], and Upper Respiratory Tract Infections in the last 2 weeks [AOR: 5.46 (3.21-10.92)] were found to be determinants of pneumonia. CONCLUSIONS: This study pointed out that the under-five pneumonia was relatively large. Factors such as hand washing before child feeding, birth to 6 months of breastfeeding, zinc supplementation of the child, diarrhea in the last 2 weeks, and Upper Respiratory Tract Infections in the last 2 weeks were determinants of under-five pneumonia. In this study, the primary risk factors for pneumonia may be preventable with no or minimal cost. Therefore, we advise suitable and sufficient health education addressing the prevention and management of pneumonia.

Efficacy and safety of tenapanor in hemodialysis patients with hyperphosphatemia: A systematic review and meta-analysis of randomized placebo-controlled trials.

BACKGROUND: The effects of tenapanor in reducing serum phosphorus in hemodialysis patients with hyperphosphatemia are uncertain and no relevant meta-analysis has been conducted. We performed a meta-analysis of randomized placebo-controlled trials to evaluate the efficacy and safety of tenapanor. METHODS: All randomized controlled trials of tenapanor were searched up to 1 August 2022. The primary endpoint was the change in serum phosphorus level from baseline with tenapanor and placebo. Data on drug-related adverse events (AEs), gastrointestinal AEs and diarrhea were collected to determine the safety of tenapanor. RESULTS: There were 533 patients throughout five trials that were eligible. Tenapanor significantly lowered blood phosphorus level by 1.79 mg/dl in the mean difference than the placebo. Diarrhea, gastrointestinal AEs, and drug-related AEs were more severe than placebo. CONCLUSIONS: This meta-analysis showed that although drug side effects were common, tenapanor significantly reduced serum phosphorus level in hemodialysis patients.

Intestinal hypomagnesemia in an Iranian patient with a novel TRPM6 variant: a case report and review of the literature.

TRPM6 is predominantly expressed in the kidney and colon and encodes a protein containing an ion channel domain and a protein kinase domain. It is crucial for magnesium homeostasis and plays important roles in epithelial magnesium transport and the active magnesium absorption. In this study, we present a 70-day-old Iranian female patient from consanguineous parents with hypomagnesemia and secondary hypocalcemia. She presented with seizures 19 days after birth and refractory watery non-bloody diarrhea. She consequently had failure to thrive. Other features included hypotonia, wide anterior fontanel, ventriculomegaly, and pseudotumor cerebri following administration of nalidixic acid. She had severe hypomagnesemia and hypocalcemia which were treated with magnesium and calcium supplementation. Despite initial unstable response to supplemental magnesium, she eventually improved and the diarrhea discontinued. The patient was discharged by magnesium and calcium therapy. At the last follow-up at age 2.5 years, the patient remained well without any recurrence or complication. Genetic testing by whole-exome sequencing revealed a novel homozygous frameshift insertion-deletion (indel) variant in exon 26 of the TRPM6 gene, c.3693-3699del GCAAGAG ins CTGCTGTTGACATCTGCT, p.L1231Ffs*36. Segregation analysis revealed the TRPM6 heterozygous variant in both parents. Patients with biallelic TRPM6 pathogenic variants typically exhibit hypomagnesemia with secondary hypocalcemia and present with neurologic manifestations including seizures. In some patients, this is also complicated by chronic diarrhea and failure to thrive. Long-term complications are rare and most of the patients show a good prognosis with supplemental magnesium therapy.

Orally Administered Probiotics in the Prevention of Chemotherapy (± Radiotherapy)-Induced Gastrointestinal Toxicity: A Systematic Review With Meta-Analysis of Randomized Trials.

BACKGROUND: Chemoradiotherapy-induced gastrointestinal toxicity may lead to a significant impairment of the oncological patient's quality of life, as well as to reduced adherence to the treatment, which may have a negative impact on survival and mortality rates. OBJECTIVE: The aim of this review was to investigate whether oral probiotic administration prevents chemotherapy (± radiotherapy)-induced gastrointestinal toxicity, particularly diarrhea. METHODS: We searched the MEDLINE, Web of Science, and SCOPUS databases for randomized controlled trials in English published between 1990 and 2020. We conducted statistical data analyses expressing the treatment effect size as a risk ratio (RR) together with a 95% confidence interval (CI). Implications are based on trials rated as having a low risk of bias (RoB). RESULTS: We included 8 trials (n = 697 participants), from which 3 studies rated as low RoB contained primary endpoint data; the risk of developing grade 3/4 diarrhea in patients receiving probiotics was reduced by 78% compared to the control group (RR = 0.22 [95% CI 0.05-1.08]; P = .06; n = 114 participants). Probiotics showed preventive effects in patients treated with chemotherapy alone (RR = 0.34 [0.12-0.94]; P = .04, n = 121 participants) and in patients with colorectal cancer (RR = 0.56 [0.34-0.92]; P = .02; n = 208 participants). The reduction in the incidence of overall diarrhea was not significant. CONCLUSIONS: Probiotics failed to prove a preventive effect of statistical significance against the development of severe and overall diarrhea in cancer patients treated with chemotherapy (± radiotherapy). However, we cannot rule out that the effects of probiotics are clinically relevant, especially in certain subgroups of patients. This needs to be clarified in further well-performed studies.

Acupoint application therapy for diarrhea-predominant irritable bowel syndrome: a protocol for systematic review and network meta-analysis.

BACKGROUND: Irritable bowel syndrome is a chronic functional gastrointestinal disease, of which diarrhea-predominant irritable bowel syndrome (IBS-D) is a common subtype. In China, acupoint application therapy is currently widely used as an effective complementary therapy for IBS-D. In the clinical management of IBS-D, acupoint application is usually combined with other therapies, including acupuncture, moxibustion, and Chinese herbal and Western medicine. However, at present, evidence regarding the most effective options for treating IBS-D is insufficient. Therefore, this protocol proposes a systematic review and network meta-analysis for evaluating the effectiveness of acupoint application and its combination therapies in treating IBS-D, and for identifying the acupoint application-related treatments with the highest probability of being the best intervention. METHODS: Six English electronic databases (PubMed, Ovid MEDLINE, Scopus, Web of Science, the Cochrane Library, and EMBASE), four Chinese electronic databases [China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (CQVIP), WanFang, and SinoMed), and one Japanese medical database (Citation Information by National Institute of Informatics (CiNii)] will be searched for eligible randomized controlled trials from their inception to June 1, 2022. The efficacy and safety of acupoint application therapy and its combination therapies for patients with IBS-D will be evaluated. The STATA 14.0 (StataCorp, USA) software package will be used for the meta-analysis. A Bayesian network meta-analysis (NMA) will be performed using R (version 4.0.2) and Aggregate Data Drug Information System (ADDIS, version 1.16.8) software packages. Bias risk will be assessed using the Cochrane Collaboration's risk of bias tool; specifically, publication bias will be evaluated using Egger's test and funnel plots. The rank probabilities of various outcomes for each intervention will be calculated, clustered, and ranked using the cumulative ranking curve method. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method will be employed to assess the certainty of evidence for NMA outcomes. CONCLUSIONS: This study will aim to determine the clinical efficacy of acupoint application therapy and its combined therapy in the treatment of IBS-D and provide an evidence-based foundation for identifying the best acupoint application program.

The Effects of Patchouli Alcohol on Diarrhea-Predominant Irritable Bowel Syndrome are Correlated with Phenotypic Plasticity in Myenteric Neurons and the Targeted Regulation of Myosin Va.

Patchouli alcohol (PA) has been widely used for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D) in traditional Chinese medicine, and the related mechanism remains to be fully understood. Our previous study has indicated that PA significantly reduced visceral sensitivity and defecation area in IBS-D rats. In this study, we prepared an IBS-D rat model and observed the dynamic intestinal motility and colonic longitudinal muscle and myenteric plexus (LMMP) neurons, as well as their subtypes at D14, D21, and D28. After PA administration, we observed the effects on the changes in intestinal motility, colonic LMMP neurons, and LMMP Myosin Va in IBS-D rats and their co-localization with inhibitory neurotransmitter-related proteins. The results indicated that PA treatment could alleviate IBS-D symptoms, regulate the abnormal expression of LMMP neurons, increase Myosin Va expression, up-regulate co-localization levels of Myosin Va with neuronal nitric oxide synthase (nNOS), and promote co-localization levels of Myosin Va with vasoactive intestinal polypeptide (VIP). In conclusion, this study demonstrated the neuropathic alterations in the colon of chronic restraint stress-induced IBS-D rat model. PA reversed the neuropathological alteration by affecting the transport process of nNOS and VIP vesicles via Myosin Va and the function of LMMP inhibitory neurons, and these effects were related to the mechanism of enteric nervous system (ENS) remodeling.

Ameliorating effects of electroacupuncture on the low-grade intestinal inflammation in rat model of diarrhea-predominant irritable bowel syndrome.

BACKGROUND AND AIM: We aim to investigate the effects and mechanisms of electroacupuncture (EA) at ST25 and ST37 on the intestinal low-grade inflammation (LGI) in rat model of Diarrhea-predominant irritable bowel syndrome (IBS-D). METHODS: IBS-D model rats were established by acetic acid enema combined with restraint and tail clamping. Before EA intervention, they were divided into three groups: blank 1 group, blank 2 group, and IBS-D model group. Diarrhea symptoms and visceral pain sensitivity were evaluated. After constructed the model successfully, the remaining IBS-D model group rats were randomly divided into model group and EA group. Local intestinal inflammation (HE staining), changes of intestinal mucosa (occludin protein and microvascular diameter) were evaluated. Differences between two groups were compared using t-test or Mann-Whitney U-test. Differences among more than two groups were compared using one-way ANOVA or Kruskal-Wallis test. RESULTS: After modeling, the results of HE staining in intestinal tract of IBS-D model rats showed LGI. Compared with the model group, 4 h fecal moisture content (diarrhea index) and the AWR score were decreased in the EA group. The results of HE in EA group showed that the infiltration of intestinal inflammatory cells were alleviated. Additionally, EA significantly upregulated the expression of occludin protein and partially dilated the intestinal microvascular diameter. Pearson correlation analysis showed that the symptoms of IBS-D rats were correlated with the changes of intestinal mucosa. CONCLUSION: EA may treat intestinal LGI in IBS-D rats by upregulating the expression of occludin protein and dilating the intestinal microvascular diameter.

Double-blinded randomised placebo controlled trial of enterosgel (polymethylsiloxane polyhydrate) for the treatment of IBS with diarrhoea (IBS-D).

OBJECTIVE: Irritable bowel syndrome with diarrhoea (IBS-D) is a common and challenging condition that significantly reduces quality of life. Enterosgel (polymethylsiloxane polyhydrate) is an intestinal adsorbent which sequesters harmful molecules and is safe and effective in acute infective diarrhoea. This randomised controlled multicentre trial aimed to investigate its safety and efficacy in patients with IBS-D. DESIGN: After a 2-week screening phase, participants were randomised into an 8-week double-blind phase, followed by an 8-week open-label and follow-up phase. Participants recorded stool consistency, pain and global symptoms in e-diaries and questionnaires. The primary outcome was the percentage of responders on a composite abdominal pain (≥30% decrease in the weekly score) and stool consistency (50% reduction in days per week with at least one stool of BSFS type 6 or 7) score during at least 4 weeks of the treatment period. RESULTS: 440 patients with IBS-D were randomised to the double-blind phase with 393 continuing to the open-label phase. The Primary outcome responder rate by intention-to-treat for enterosgel versus placebo was 37.4% vs 24.3% (OR 1.95, NNT 8, p=0.002). Enterosgel also improved stool consistency (48.5% vs 32.5%, p<0.0001) abdominal pain (53.3% vs 40.2%, p=0.003), stool frequency (treatment effect -0.32 (-0.62 to -0.02)) and urgency (treatment effect -0.59 (-0.85 to -0.33)). 60% of patients reported adequate relief of symptoms after open-label treatment. Adverse event frequency was similar in both groups, with no serious events attributable to enterosgel. CONCLUSION: Enterosgel is safe and effective in IBS-D, providing an alternative to the limited current treatment options. TRIAL REGISTRATION NUMBER: ISRCTN17149988.

Efficacy and safety of Qinghua Zhixie Decoction against diarrhea-predominate irritable bowel syndrome: A protocol for a randomized controlled trial.

BACKGROUND: Diarrhea-predominant irritable bowel syndrome (D-IBS) is the main subtypes of irritable bowel syndrome (IBS). In recent years, more than half of IBS patients have received complementary and alternative medicine. Traditional Chinese herbal formula is widely used in Asia, and clinical studies have also found that Chinese herbal formula could significantly improve abdominal pain and diarrhea. We plan to carry out a randomized, controlled, double blind, clinical studies to observe the clinical efficacy of Qinghua Zhixie decoction in the treatment of D-IBS. METHODS: Four hundred sixty-four participants will be randomly assigned to the treatment group and control group. Patients in both groups would take medications and stimulations simultaneously. The outcomes of IBS symptom severity score, quality of life, psychological states, and recurrence rate will be recorded. Statistics will be analyzed with the SPSS 22.0. CONCLUSIONS: The findings of the study will identify the safety and efficacy of Qinghua Zhixie decoction in the treatment of D-IBS.

Assessment of the incidence and etiology of nosocomial diarrhea in a medical ward in Iraq.

This study aimed to detect the incidence, etiology, risk factors, and severity of nosocomial diarrhea among adult inpatients in a medical ward in Iraq. The study was conducted among patients admitted to the medical ward from June 1, 2019, to January 31, 2020, in AL-Sader medical city. The surveillance for nosocomial diarrhea was performed by monitoring every patient in the ward 3 times/week. 1050 patients were admitted to the medical ward in AL-Sader medical city. Of these, 52 patients (mean age 58±12.91 years, range 32 to 80) developed new-onset diarrhea during hospitalization. There was a significant relationship between the severity of diarrhea and age, residence, antibiotic use, including number and duration of antibiotics, immunosuppressive agents (steroids/chemotherapy), duration of hospital stay, level of consciousness, and enema use. Nosocomial diarrhea is a significant clinical problem that complicates about 5% of all admission in the medical ward. Various microorganisms account for nosocomial diarrhea, including E. histolytica, G. lamblia, and Candida. Several risk factors associated with the severe form of nosocomial diarrhea include old age, antibiotic use, immunosuppressive use, and length of hospital stay.

[CHU Hao-ran's experience in treatment of diarrhea-predominant irritable bowel syndrome with acupuncture and moxibustion].

Professor CHU Hao-ran believes that the clinical diagnosis and treatment of diarrhea-predominant irritable bowel syndrome with acupuncture and moxibustion should concentrate on the integration of disease and syndrome differentiation. According to the evolution of pathogenesis, this disease is divided into 4 stages, i.e. invasion of exogenous pathogens, liver stagnation and spleen deficiency, spleen and kidney yang deficiency and interaction of cold and heat. Hence, the treatment should be provided by stages. Focusing on regulating the spleen and stomach, a specific acupuncture-moxibustion prescription is proposed, including Tianshu (ST 25), Zhongwan (CV 12), Zusanli (ST 36) and Shangjuxu (ST 37). Additionally, the combination of distal and nearby acupoints is considered and an unique needling manipulation, named the fight between dragon and tiger, is exerted. On the base of syndrome and meridian differentiation, the modern medicine is combined, stressing on the mind regulation and the mutual application of acupuncture and moxibustion in treatment. Eventually, a distinctive treatment system with acupuncture and moxibustion is formed for "regulating the spleen and stomach and differentiating meridians".

Transcutaneous Electrical Acustimulation Improved the Quality of Life in Patients With Diarrhea-Irritable Bowel Syndrome.

BACKGROUND AND AIM: Patients with diarrhea-dominant irritable bowel syndrome (IBS-D) experience abdominal pain and reduced quality of life and need effective treatments. This study aimed to evaluate whether transcutaneous electrical acustimulation (TEA) at two acupuncture points, LI4 and ST36, could improve pain and quality of life of patients with IBS-D. MATERIALS AND METHODS: A total of 42 patients with IBS-D who met the Rome IV criteria were randomly divided into two groups: TEA and sham-TEA. TEA was performed through acupoints Hegu (LI4) and Zusanli (ST36) for one hour twice daily for one month, using previously established parameters; sham-TEA was delivered in the same way as TEA but without actual electrical current stimulation. RESULTS: The sham-TEA group showed a significantly higher rate of drop-out than the TEA group (29% vs 0%, p = 0.021). TEA, but not sham-TEA, significantly improved quality of life (before: 78.55 ± 9.62, after: 85.97 ± 9.49, p < 0.0001). Both TEA and sham-TEA reduced abdominal pain; however, TEA was more potent than sham-TEA (p = 0.014). The IBS symptom severity scale score was reduced by both TEA and sham-TEA. Autonomic functions assessed by plasma norepinephrine and pancreatic polypeptide were not altered with TEA, nor was interleukin 10 or interleukin 6. CONCLUSIONS: TEA at LI4 and ST36 improves abdominal pain and quality of life of patients with IBS-D, probably mediated by mechanisms other than autonomic function or inflammatory cytokines.

Successful treatment of ascites accumulation and diarrhea associated with protein-losing enteropathy with oral equine placenta extract supplementation in a dog: A case report.

Background: Protein-losing enteropathy (PLE) is characterized by leakage of serum proteins into the intestinal lumen, indicating hypoproteinemia. Immunosuppressive agents are the mainstay of treatment, but in many cases, patients are forced to taper off early owing to the induction of liver damage. Case Description: An 8-year-old, non-spayed female Chihuahua presented with diarrhea and ascites effusion lasting 2 weeks. Based on the results of radiography and blood tests, a diagnosis of PLE was made. Prednisolone (3 mg/kg semel in die [SID]) and MitoMax (200 mg/day) were administered, but ascites accumulation and diarrhea did not improve. Thus, azathioprine (2 mg/kg/day) was added, but there was no improvement, and liver damage developed. The liver injury did not improve immediately, but diarrhea and ascites effusion improved after serum total protein and serum albumin levels increased after they had decreased. Subsequent tapering of prednisolone from 3 mg/kg SID to 1 mg/kg SID, combined with MitoMax (200 mg/day) and equine placenta extract (eqPE) (2 ml/day), resulted in no recurrence of ascites or diarrhea. Conclusion: In canine PLE with prolonged diarrhea and ascites effusion, supplementation with eqPE may be considered a reasonable additional therapeutic strategy.

[Diarrhea-predominant irritable bowel syndrome of spleen deficiency and damp excess treated with fire needling therapy with filiform needle and acupoint application therapy: a randomized controlled trial].

OBJECTIVE: To compare the clinical therapeutic effect on diarrhea-predominant irritable bowel syndrome (IBS-D) of spleen deficiency and damp excess among fire needling therapy with filiform needle combined with acupoint application therapy, simple acupoint application therapy and pinaverium bromide tablets, and explore the mechanism on the improvements in IBS-D. METHODS: A total of 150 patients with IBS-D of spleen deficiency and damp excess were randomized into a combined treatment group (50 cases, 14 cases dropped off), an acupoint application group (50 cases, 16 cases dropped off ) and a western medication group (50 cases, 13 cases dropped off ). In the western medication group, pinaverium bromide tablets were prescribed for oral administration, 50 mg per time, three times a day. In the acupoint application group, the herbal plaster of shenling baizhu powder mixed with fresh ginger juice was placed on Shenque (CV 8), once every two days. In the combined treatment group, on the base of the treatment as the acupoint application group, the fire needling therapy with filiform needle was exerted at Tianshu (ST 25), Shangjuxu (ST 37), Yinlingquan (SP 9) and Dachangshu (BL 25), once every two days. The duration of treatment in each group was 4 weeks. Separately, before treatment and after 7 and 28 days of treatment, the score of clinical symptoms and the score of quality of life scale for IBS (IBS-QOL) were observed in each group. Before treatment and after 28 days of treatment, the levels of , and T lymphocytes, and the ratio of / in peripheral blood of patients were detected successively; as well as the expressions of 5-HT3R mRNA and 5-HT4R mRNA in colon mucosal tissues in each group separately. RESULTS: Except the score for abdominal pain in the acupoint application group and the scores for abdominal pain and abdominal distention in the western medication group after 7 days of treatment, the scores for abdominal pain, abdominal distention, defecation frequency, stool form and incomplete bowel movement after 7 and 28 days of treatment were all reduced as compared with those before treatment in each group separately (P<0.05). After 7 days of treatment, the scores for abdominal distention, defecation frequency and stool form in the combined treatment group were all lower than those in the western medication group (P<0.05). After 28 days of treatment, the score of each clinical symptom in the combined treatment group was lower than either of the rest two groups respectively (P<0.05); and the scores for abdominal pain, abdominal distention and incomplete bowel movement in the acupoint application group were lower than those in the western medication group separately (P<0.05). After 7 and 28 days of treatment, the score of each item in IBS-QOL was increased as compared with that before treatment in each group (P<0.05). After 7 days of treatment, except the scores for heterosexual relationship and human relations, scores of the other items, other scores of IBS-QOL in the combined treatment group were higher than those in the western medication group separately (P<0.05); while the scores of anxiety and behavior disorder in the acupoint application group were higher than those in the western medication group (P<0.05). After 28 days of treatment, the each score of IBS-QOL in the combined treatment group was higher than the other two groups respectively (P<0.05), while the scores of anxiety, behavior disorder, dietary control, social reaction and human relations in the acupoint application group were all higher than the western medication group (P<0.05). After treatment, the levels of and T lymphocytes and the ratio of /in peripheral blood, as well as the expressions of 5-HT4R mRNA in colon tissue were all increased in each group (P<0.05), but the levels of T lymphocyte and 5-HT3R mRNA expressions in colon tissue were reduced in each group (P<0.05). After treatment, regarding the levels of and T lymphocytes and the ratio of /in peripheral blood, as well as the expressions of 5-HT4R mRNA in colon tissue, the values in the combined treatment group were all higher than either of the rest two groups respectively (P<0.05), while the values in the acupoint application group were higher than the western medication group (P<0.05). Concerning to the level of T lymphocytes and 5-HT3R mRNA expression, the values in the combined treatment group were lower than the rest two groups respectively (P<0.05), and the values in the acupoint application group were lower than the western medication group (P<0.05). CONCLUSION: The combined treatment with the fire needling therapy with filiform needle and the acupoint application therapy effectively relieves the clinical symptoms, improves the quality of life and strengthens the immunity in the patients with IBS-D. The therapeutic effect of this combined regimen is better than either simple acupoint application therapy or the oral medication of pinaverium bromide. The mechanism may be related to the regulation of the levels of T lymphocyte subsets and the modulation of the expressions of 5-HT3R and 5-HT4R mRNA in colon tissue.

Efficacy and safety of Qingre-Chushi therapies in active ulcerative colitis: A network meta-analysis.

BACKGROUND: Ulcerative colitis (UC) is a chronic inflammatory disease with an increasing incidence in the world. Qingre-Chushi therapies (QC) can alleviate clinical symptoms. Therefore, a network meta-analysis was conducted to systematically evaluate the efficacy and safety of QC in the treatment of active UC patients. METHODS: 7 databases were screened and relevant randomized controlled trials were selected. The tools of Cochrane Handbook and the GRADE system were conducted to assess the quality of outcomes. Pooled risk ratio or standard mean difference was calculated with 95% credible interval for outcomes measurement using the random-effects model. The surface under the cumulative ranking curve (SUCRA) was performed to rank the treatments. The larger SUCRA scores, the more effective interventions. RESULTS: A total of 3560 articles were identified and 21 studies including 1829 participants were included for further analysis. Totally, 9 therapies regimens were compared: oral mesalazine, mesalazine enema, mesalazine suppository, oral mesalazine + mesalazine enema, oral QC, oral QC + oral mesalazine, QC enema, oral QC + QC enema, and oral mesalazine + QC enema. Based on the SUCRA plot, oral QC + oral mesalazine was the best treatment in inducing clinical response; oral QC + QC enema had the best efficacy in the improvement of Mayo scores and alleviating abdominal pain; oral mesalazine + mesalazine enema was the optimal therapy in the endoscopic improvement and reducing diarrhea; QC enema + oral mesalazine was the best option in preventing bloody stool. CONCLUSION: This study confirmed the efficacy and safety of QC in treating active UC and suggested that the combination of oral medications with topical can achieve more benefits.

Biologic therapy for amyloid A amyloidosis secondary to rheumatoid arthritis treated with interleukin 6 therapy: Case report and review of literature.

INTRODUCTION: Secondary amyloidosis is a rare complication of rheumatoid arthritis (RA) that is histologically characterized by the deposition of amyloid fibrils in target organs, such as the kidneys and gastrointestinal tract. Controlling the inflammatory response is essential to prevent organ dysfunction in amyloid A (AA) amyloidosis secondary to RA, and no clear treatment strategy exists. PATIENT CONCERNS AND DIAGNOSIS: A 66-year-old woman with RA, who had been treated with disease-modifying anti-rheumatic drugs for 1 year, presented with recurrent abdominal pain and prolonged diarrhea. Endoscopy showed chronic inflammation, and colon tissue histology confirmed AA amyloidosis. INTERVENTIONS AND OUTCOMES: After tocilizumab therapy was begun, her diarrhea and abdominal pain subsided, and articular symptoms improved. Biologic drugs for RA have been used in patients with secondary AA amyloidosis, including tumor necrosis factor and Janus kinase inhibitors, interleukin 6 blockers, and a T cell modulator. Here, we systematically review existing case reports and compare the outcomes of RA-related AA amyloidosis after treatment with various drugs. CONCLUSION: The data indicate that biologic drugs like tocilizumab might be treatments of choice for AA amyloidosis secondary to RA.

Zinc deficiency and its association with treatment-related toxicity in children with cancer.

BACKGROUND: Nutritional deficiencies in children with cancer at time of diagnosis and during treatment may negatively affect disease outcome and increase treatment-related toxicity. Yet zinc, an essential nutrient important for supporting immune function and known for reducing diarrheal episodes, is rarely assessed in these children. PROCEDURES: Fifty children (1 month to 18 years) with recently diagnosed cancer were enrolled in this study. An age and gender matched control group (n = 50) was also recruited. Plasma and urinary zinc, plasma copper, and C-reactive protein (CRP) levels were measured at baseline, 3, and 6 months following diagnosis. A retrospective review of the toxicity profile was performed in the cohort of children with cancer for the first 4 years after initial diagnosis. RESULTS: CRP and plasma copper (both acute-phase reactants) were elevated in patients with cancer compared to controls at baseline, both p < .03. Plasma zinc levels were not significantly different from controls at baseline, but decreased by 11% in the cancer group over 6 months of treatment, 83.2 ± 15.6 to 74.3 ± 14.8 µg/dl, p = .01. Plasma zinc dropped to deficient levels in 35% of cases over the initial 6 months. Zinc deficiency at 6 months was related to an increased incidence of severe diarrhea during 4 years of follow-up, p < .001. CONCLUSIONS: Zinc deficiency is an underrecognized problem among patients undergoing treatment for cancer and is associated with severe diarrhea. Further studies are needed to evaluate causes for zinc deficiency, related effects, and a possible role for zinc supplementation.
