Impact of psychological stress on irritable bowel syndrome

Psychological stress is an important factor for the development of irritable bowel syndrome(IBS). More and more clinical and experimental evidence showed that IBS is a combination of irritable bowel and irritable brain. In the present review we discuss the potential role of psychological stress in the pathogenesis of IBS and provide comprehensive approaches in clinical treatment. Evidence from clinical and experimental studies showed that psychological stresses have marked impact on intestinal sensitivity, motility, secretion and permeability, and the underlying mechanism has a close correlation with mucosal immune activation, alterations in central nervous system, peripheral neurons and gastrointestinal microbiota. Stress-induced alterations in neuro-endocrine-immune pathways acts on the gut-brain axis and microbiota-gut-brain axis, and cause symptom flare-ups or exaggeration in IBS. IBS is a stresssensitive disorder, therefore, the treatment of IBS should focus on managing stress and stress-induced responses. Now, non-pharmacological approaches and pharmacological strategies that target on stress-related alterations, such as antidepressants, antipsychotics, miscellaneous agents, 5-HT synthesis inhibitors, selective 5-HT reuptake inhibitors, and specific 5-HT receptor antagonists or agonists have shown a critical role in IBS management. A integrative approach for IBS management is a necessary.

在 polycystic 定义 bariatric 外科的角色卵巢的症候群病人

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in women.To meet PCOS criteria,women must have a combination of hyperandrogenism,anovulation and ultrasound findings.Almost 10% of all reproductive age women worldwide show signs of PCOS.Although women often seek care for gynecological or body image concerns,many PCOS women are at risk for metabolic syndrome (MS).Many of the metabolic consequences are overlooked and un-dertreated by physicians because these patients tend to be young,reproductive age women.MS and obesity coexist commonly with PCOS.These young women are predisposed to glucose abnormalities and ulti-mately diabetes mellitus,dyslipidemia and eventually cardiovascular disease.Bariatric surgery can be an ef-fective means of weight loss in PCOS women.Surgical techniques have become safer and less invasive over time and have been found to be effective in achieving significant weight loss.Surgical options have also in-creased,giving patients more choices.Bariatric surgery may prevent or reverse metabolic syndrome.Bariatric surgery may also have reproductive benefits in PCOS patients.Although bariatric surgery has historically been performed in older,reproductive aged women,it has recently gained favor in adolescents as well.This is of particular importance due to the prevalence of both PCOS and MS in adolescents.Treatment of PCOS and MS certainly requires a combination of medical therapy,psychological support and lifestyle modifications.These treatments are difficult and often frustrating for pa-tients and physicians.Bariatric surgery can be effective in achieving significant weight loss,restoration of the hypothalamic pituitary axis,reduction of cardiovascular risk and even in improving pregnancy outcomes.Ulti-mately,bariatric surgery should be considered part of the treatment in PCOS women,especially in those with MS.

Magnetic resonance imaging correlates of bee sting induced multiple organ dysfunction syndrome: A case report

Occasionally systemic complications with high risk of death,such as multiple organ dysfunction syndrome(MODS),can occur following multiple bee stings.This case study reports a patient who presented with MODS,i.e.,acute kidney injury,hepatic and cardiac dysfunc-tion,after multiple bee stings.The standard clinical findings were then correlated with magnetic resonance imaging(MRI)findings,which demonstrates that MRI may be utilized as a simpler tool to use than other mul-tiple diagnostics.

High-sensitivity cardiac troponins in everyday clinical practice

High-sensitivity cardiac troponin(hs-cTn) assays are increasingly being used in many countries worldwide,however,a generally accepted definition of high-sen-sitivity is still pending.These assays enable cTn mea-surement with a high degree of analytical sensitivity with a low analytical imprecision at the low measuring range of cTn assays(coefficient of variation of < 10% at the 99th percentile upper reference limit).One of the most important advantages of these new assays is that they allow novel,more rapid approaches to rule in or rule out acute coronary syndromes(ACSs) than with previous cTn assay generations which are still more commonly used in practice worldwide.hs-cTn is also more sensitive for the detection of myocardial damage unrelated to acute myocardial ischemia.Therefore,the increase in early diagnostic sensitivity of hs-cTn assays for ACS comes at the cost of a reduced ACS specificity,because more patients with other causes of acute or chronic myocardial injury without overt myocardial isch-emia are detected than with previous cTn assays.As hs-cTn assays are increasingly being adopted in clinical practice and more hs-cTn assays are being developed,this review attempts to synthesize the available clinical data to make recommendations for their everyday clini-cal routine use.

Nifekalant in the treatment of life-threatening ventricular tachyarrhythmias

The aim of the present study is to review the literature and discuss nifekalant's potential use as a first aid drug in an emergency care setting.The PubMed database was used to identify papers,using Keywords nifekalant,MS-551,amiodarone and lidocaine.Nifekalant hydrochloride,formally known as MS-551,is a classⅢ antiarrhythmic agent which acts only by increasing the time course of myocardial repolarization.It was developed and is currently being used only in Japan for the treatment of ventricular tachyarrhythmias.It is a non-selective K+channel blocker without any β-blocking actions.Administration of nifekalant suppressed sustained ventricular tachyarrhythmias in acute coronary syndrome patients,and in cardiac arrest victims as well as during or after cardiac surgery.The major adverse effect of nifekalant is QT interval prolongation and occurrence of torsades de pointes which requires frequent monitoring of the QT interval during nifekalant infusion with adequate dose adjustment.Nifekalant is a possible effective antiarrhythmic agent for refractory ventricular tachyarrhythmias.Further clinical studies are required before nifekalant is routinely used in the emergency care setting.

Cognitive behavioral approach to understanding irritable bowel syndrome

Irritable bowel syndrome(IBS)is considered a biopsychosocial disorder,whose onset and precipitation are a consequence of interaction among multiple factors which include motility disturbances,abnormalities of gastrointestinal sensation,gut inflammation and infection,altered processing of afferent sensory information,psychological distress,and affective disturbances.Several models have been proposed in order to describe and explain IBS,each of them focusing on specific aspects or mechanisms of the disorder.This review attempts to present and discuss different determinants of IBS and its symptoms,from a cognitive behavioral therapy framework,distinguishing between the developmental predispositions and precipitants of the disorder,and its perpetuating cognitive,behavioral,affective and physiological factors.The main focus in understanding IBS will be placed on the numerouspsychosocial factors,such as personality traits,early experiences,affective disturbances,altered attention and cognitions,avoidance behavior,stress,coping and social support.In conclusion,a symptom perpetuation model is proposed.

Nerve biopsy findings contribute to diagnosis of multiple mononeuropathy: 78% of findings support clinical diagnosis

Multiple mononeuropathy is an unusual form of peripheral neuropathy involving two or more nerve trunks. It is a syndrome with many different causes. We reviewed the clinical, electrophysi- ological and nerve biopsy findings of 14 patients who suffered from multiple mononeuropathy in our clinic between January 2009 and June 2013. Patients were diagnosed with vasculitic neurop- athy （n = 6）, perineuritis （n = 2）, chronic inflammatory demyelinating polyradiculoneuropathy （n = 2） or Lewis-Sumner syndrome （n = 1） on the basis of clinical features, laboratory data, elec- trophysiological investigations and nerve biopsies. Two patients who were clinically diagnosed with vasculitic neuropathy and one patient who was clinically diagnosed with chronic inflamma- tory demyelinating polyradiculoneuropathy were not confirmed by nerve biopsy. Nerve biopsies confirmed clinical diagnosis in 78.6% of the patients （11/14）. Nerve biopsy pathological diagno- sis is crucial to the etiological diagnosis of multiple mononeuropathy.

Differences in acquired immune deficiency syndrome treatment and evaluation strategies between Chinese and Western Medicine

Complementary and alternative medicine, including Chinese medicine(CM), has been used to treat acquired immune deficiency syndrome(AIDS) for almost 30 years. We aimed to compare the main differences between AIDS treatment and evaluation strategies between CM and Western Medicine(WM), and analyze advantages and disadvantages.The characteristics of integrative medicine(IM),based on CM and WM, include a patient-centered mode of medicine based on evidence. IM focuses on complex intervention and management with systemic and individual treatment. The evaluation indexes of IM might consist of objective indicators and subjective indexes. IM might be a more valuable method for treating AIDS in the future instead of WM or CM alone.

Study on factors affecting TB/HIV co-infection in four counties of China

The factors affecting case detection of tuber-culosis(TB)/human immunodeficiency virus(HIV)co-infection cases were explored in order to provide evidence-based formulation of a TB/HIV co-infection control strategy in China.Four counties with different modes of HIV transmission and varying cooperation mechanisms between TB and HIV institutions were selected.HIV test among TB patients and TB examination among people living with HIV/acquired immunodeficiency syndrome(AIDS)were conducted.Patients also completed ques-tionnaires on potential factors affecting TB/HIV co-infection.The results showed that 19(1.7%)were HIV-positive among 1089 cases of people living with active TB who received HIV testing.Conversely,there were 126(10%)cases of active TB among 1255 cases of people living with HIV/AIDS.Among the newly discovered 145 cases of TB/HIV co-infection,AIDS institutions found 86.9%of these co-infections and 14.1%came from TB institutes.In different registration categories,there were 31(21.4%)cases of smear positive TB,104(71.7%)cases of smear negative TB,and extrapulmonary cases accounted for 10(6.9%).Gender,occupation,marital status,ethnic group,education,HIV transmission route,CD4 level,and type of TB susceptible symptoms had significant effects on whether HIV/AIDS patients were co-infected with TB disease(P<0.01).Sex,age,ethnic group,occupation,and type of tuberculosis had no significant influence on whether TB patients had HIV infection.AIDS institutions couldfind more TB/HIV co-infection patients in compar-ison with TB institutions,particularly in patients with smear negative pulmonary tuberculosis and extrapulmon-ary tuberculosis.Therefore,a cooperation mechanism should be built up between TB and HIV control systems,and routine TB checks should be conducted for HIV/AIDS patients.In areas where sex or drug use is the major transmission mode of HIV infection,antiretroviral therapy should be expanded,treatment adherence should be improved and patients’immunity level should be increased in order to decrease TB incidence.Cough and expectora-tion of more than two weeks,bloody sputum,and recurrent fevers could be revealing symptoms in TB screening of HIV/AIDS patients.
