Heart rate variability and the influence of craniosacral therapy on autonomous nervous system regulation in persons with subjective discomforts： a pilot study

BACKGROUND： Subjective discomforts in a preclinical range are often due to imbalanced autonomic nervous system activity, which is a focus of craniosacral therapy. OBJECTIVE： The aim of this work was to determine any changes in heart rate variability （HRV） in a study on craniosacral therapy. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS： This is a quasi-experimental （controlled） study with cross-over design. In a private practice, measurements were performed on 31 patients with subjective discomforts before and after a control and an intervention period. HRV was determined using a device that requires a measuring time of 140 s and electrode contact only with the fingertips. Main PRIMARY OUTCOME MEASURES： HRV change under the influence of a defined onetime intervention （test intervention） with craniosacral therapy versus control （defined rest period）. RESULTS： Standard deviation of all RR-intervals （ms） and total power of RR-interval variability in the frequency range （ms2） were together interpreted as an indicator of test subjects＇ autonomic nervous activity and as a measure of their ability to cope with demands on their health. Neither of these parameters increased during the control period （P〉0.05）, whereas during the test intervention period there was an increase in both （P〈0.05, P〈0.01）. Nevertheless, interactions between treatment and the increase were statistically not significant （P〉0.05）. No changes were observed in the low frequency/high frequency ratio （sympathetic-vagal balance） in the course of the control or the test intervention period （P〉0.05）. CONCLUSION： Craniosacral treatment had a favourable effect on autonomic nervous activity. This in itself is an interesting result, but further research will be needed to distinguish specific effects of craniosacral therapy technique from less specific therapist-client interaction effects.     

Clinical manifestations of imaging demonstrations of AIDS-related nervous system infections

HIV is a neurotropic virus and can be engulfed macrophagocytes. It invades the brain tissue via the blood-brain barrier and multiplies in the cerebrospinal fluid （CSF）. HIV has been isolated from the brain, spinal marrow, peripheral nerve, and the CSF. Electronic microscopy, immunohistochemistry, and in situ hybridization have demonstrated monocytes and multinucleated cells containing HIV virus.     

Antiviral therapy for ＂difficult-to-treat＂ hepatitis C virus-infected patients

Objective To review the updated research on direct antiviral agents （DAAs）-including regimens for hepatitis C virus （HCV）,and focus on ＂difficult-to-treat＂ HCV-infected patients.Data sources The literature concerning DAAs and hepatitis C cited in this review was collected from PubMed and Google Scholar databases published in English up to July 2013.Study selection Data from published articles regarding HCV and DAAs in clinical trials and in clinical use were identified and reviewed.Results It was recognized that some ＂difficult-to-treat＂ patients would still exist,even though stronger treatments using such as DAAs,including telaprevir and boceprevir,which lead to higher sustained virological response rates,are available.Such patients include those with advanced fibrosis/cirrhosis,elderly persons,children,HCV-human immunodeficiency virus co-infected patients,HCV-infected recipients,and so on.Conclusions Certain ＂difficult-to-treat＂ patients would still exist,even though stronger treatment is available.Although evidence from clinical trials is still lacking,interferon-sparing regimens could have stronger effects for eradicating HCV in such cases.     

Saffron （Crocus sativus L.） and major depressive disorder： a meta-analysis of randomized clinical trials

Due to safety concerns and side effects of many antidepressant medications, herbal psychopharmacology research has increased, and herbal remedies are becoming increasingly popular as alternatives to prescribed medications for the treatment of major depressive disorder （MDD）. Of these, accumulating trials reveal positive effects of the spice saffron （Crocus sativus L.） for the treatment of depression. A comprehensive and statistical review of the clinical trials examining the effects of saffron for treatment of MDD is warranted. OBJECTIVE： The purpose of this study was to conduct a meta-analysis of published randomized controlled trials examining the effects of saffron supplementation on symptoms of depression among participants with MDD. SEARCH STRATEGY： We conducted electronic and non-electronic searches to identify all relevant randomized, double-blind controlled trials. Reference lists of all retrieved articles were searched for relevant studies. INCLUSION CRITERIA： The criteria for study selection included the following： （1） adults （aged 18 and older） with symptoms of depression, （2） randomized controlled trial, （3） effects of saffron supplementation on depressive symptoms examined, and （4） study had either a placebo control or antidepressant comparison group. DATA EXTRACTION AND ANALYSIS： Using random effects modeling procedures, we calculated weighted mean effect sizes separately for the saffron supplementation vs placebo control groups, and for the saffron supplementation vs antidepressant groups. The methodological quality of all studies was assessed using the Jadad score. The computer software Comprehensive Meta- analysis 2 was used to analyze the data. RESULTS： Based on our pre-specified criteria, five randomized controlled trials （n = 2 placebo controlled trials, n = 3 antidepressant controlled trials） were included in our review. A large effect size was found for saffron supplementation vs placebo control in treating depressive symptoms （M ES = 1.62, P 〈 0.001）, revealing that saffron supplementation significantly reduced depression symptoms compared to the placebo control. A null effect size was evidenced between saffron supplementation and the antidepressant groups （M ES = -0.15） indicating that both treatments were similarly effective in reducing depression symptoms. The mean Jadad score was 5 indicating high quality of trials. CONCLUSION： Findings from clinical trials conducted to date indicate that saffron supplementation can improve symptoms of depression in adults with MDD. Larger clinical trials, conducted by research teams outside of Iran, with long-term follow-ups are needed before firm conclusions can be made regarding saffron＇s efficacy and safety for treating depressive symptoms.     

Chinese herbal medicine Xinfeng Capsule in treatment of rheumatoid arthritis： study protocol of a multicenter randomized controlled trial

BACKGROUND： Rheumatoid arthritis （RA）, as a common systemic inflammatory autoimmune disease, affects approximately 1 in 100 individuals. Effective treatment for RA is not yet available because current research does not have a clear understanding of the etiology and pathogenesis of RA. Xinfeng Capsule, a patent Chinese herbal medicine, has been used in the treatment of RA in recent years. Despite its reported clinical efficacy, there are no large-sample, multicenter, randomized trials that support the use of Xinfeng Capsule for RA. Therefore, we designed a randomized, double-blind, multicenter, placebo-controlled trial to assess the efficacy and safety of Xinfeng Capsule in the treatment of RA. METHODS AND DESIGN： This is a 12-week, randomized, placebo-controlled, double-blind, multicenter trial on the treatment of RA. The participants will be randomly assigned to the experimental group and the control group at a ratio of 1：1. Participants in the experimental group will receive Xinfeng Capsule and a pharmaceutical placebo （imitation leflunomide）. The control group will receive leflunomide and an herbal placebo （imitation Xinfeng Capsule）. The American College of Rheumatology （ACR） Criteria for RA will be used to measure the efficacy of the Xinfeng Capsule. The primary outcome measure will be the percentage of study participants who achieve an ACR 20% response rate （ACR20）, which will be measured every 4 weeks after randomization. Secondary outcomes will include the ACR50 and ACR70 responses, the side effects of the medications, the Disease Activity Score 28, RA biomarkers, quality of life, and X-rays of the hands and wrists. The first four of the secondary outcomes will be measured every 4 weeks and the others will be measured at baseline and after 12 weeks of treatment. DISCUSSION： The result of this trial will help to evaluate whether Xinfeng Capsule is effective and safe in the treatment of RA. TRIAL REGISTRATION： This trial has been registered in ClinicalTrials.gov. The identifier is N CT01774877.     

WHO西太区与世界中医药学会联合会中医名词术语国际标准比较研究：八纲辨证（三）

The Chinese characters 寒 and 热, 虚, and 实 are quite common concepts in Chinese language. However in traditional Chinese medicine （TCM）, they are used as four principles in syndrome differentiation. In terms of translation, 寒 and 热 are very easy to understand and can be simply translated as ＂cold＂ and ＂heat＂. But the transla- tion of 虚 and 实 used to be a problem. For a quite long time in translation practice,     

Relevance of muscle biopsy for diagnosing multifocal motor neuropathy

Multifocal motor neuropathy （MMN） is a rare,.focal,inflammatory,demyelinating disease of the peripheral nerves with pure motor involvementJ MMN is clinically characterized by slowly progressive,asymmetric,distal,upper limb predominant weakness,in the absence of sensory disturbances） Weakness is usually multifocal and connected to a distinct motor nerve,such as the musculocutaneous nerve resulting in biceps weakness,the posterior interosseus nerve resulting in finger drop,the median,ulnar,or radial nerve resulting in dexterity problems or grip weakness,or the peroneal nerve resulting in a foot drop.Onset of clinical manifestations is between 20 and 50 years of age.The prevalence of MMN is reported as 1-2 per 100 000.2 MMN is three times more frequent in men as compared to women.     

Integrative techniques using acupuncture,Chinese herbal medicine,diet, and supplements for polycystic ovary syndrome： a case report

Patients with a diagnosis of polycystic ovary syndrome （PCOS） are on the rise. About 4%-12% of women are currently estimated to have this condition. It is hypothesized that PCOS appears in women who have long-standing insulin resistance （1R）, which leads to high androgen and testosterone levels; this ultimately disrupts their menstrual cycles. Some researchers attribute IR to genetic factors, although there have been only minute changes in the human genome in the past 20 000 years. However, even with a stable gene pool, genes can be turned on and offby the environment, food and air quality and toxin exposure.     

Large and giant medial sphenoid wing meningiomas involving vascular structures: clinical features and management experience in 53 patients

Background Large and giant medial sphenoid wing meningiomas that are located deeply in the skull base where they are closely bounded by cavernous sinus,optic nerve,and internal carotid artery make the gross resection hard to achieve.Also,this kind of meningiomas is often accompanied by a series of severe complications.Therefore,it was regarded as a formidable challenge to even the most experienced neurosurgeons.This study aimed to investigate the clinical features and management experience of patients with large and giant medial sphenoid wing meningiomas.Methods In this study,53 patients （33 female and 20 male,mean age of 47.5 years） with large and giant medial sphenoid wing meningiomas were treated surgically between April 2004 to March 2012,with their clinical features analyzed,management experience collected,and treatment results investigated retrospectively.Results In this study,gross total resection （Simpson Ⅰ and Ⅱ） was applied in 44 patients （83％）.Fifty-three patients had accepted the routine computed tomography scan and magnetic resonance imaging scan as postoperative neuroradiological evaluation.Their performance showed surgical complications of vascular lesions and helped us evaluate patients＇ conditions,respectively.Meanwhile,the drugs resisting cerebral angiospasm,such as Nimodipine,were infused in every postoperative patient through vein as routine.As a result,11 patients （21％） were found to have secondary injury of cranial nerves Ⅱ,Ⅲ,and Ⅳ,and nine patients got recovered during the long-term observing follow-up period.Temporary surgical complications of vascular lesions occurred after surgery,such as cerebral angiospasm,ischemia,and edema;24 patients （45％） appeared to have infarction and dyskinesia of limbs.Overall,visual ability was improved in 41 patients （77％）.No patient died during the process.Conclusions Microsurgical treatment may be the most effective method for the large and giant medial sphenoid wing meningiomas.The surgical strategy should focus on survival and postoperative living quality.

An antiretroviral regimen containing 6 months of stavudine followed by long-term zidovudine for first-line HIV therapy is optimal in resource-limited settings: a prospective, multicenter study in China

Background An zidovudine （AZT）-substitution regimen containing 24-week stavudine （d4T） followed by long-term AZT for HIV therapy is potential to trade off short-term AZT-related anemia and long-term risks associated with d4T in resourcelimited settings.However,evidence is scarce.This study aims to assess the efficacy and safety of AZT-substitution regimen,aiming to find a regimen with better efficacy,less adverse events,and more affordability in resource-limited settings.Methods This prospective,multicenter study enrolled 499 （190 on d4T regimen,172 on AZT regimen,and 137 on AZT-substitution regimen） HIV-1-infected subjects who initiated combined antiretroviral therapy and attended follow-up visits over 96 weeks from 2009 to 2011.Lamivudine （3TC） and either nevirapine （NVP） or efavirenz （EFV） were the other two drugs in the antiretroviral regimens.Virologic and immunologic responses and adverse events were monitored at baseline and at weeks 4,12,24,36,48,60,72,84,and 96.Results In terms of hematological adverse effects,AZT-substitution group had similar safety profiles to d4T group and was superior to AZT group.In comparison with AZT-substitution group,AZT group was associated with higher risk of developing anemia （adjusted hazard ratio （aHR）for anemia ≥ grade Ⅱ,8.44,95％ CI 1.81-39.46） and neutropenia （aHR for neutropenia ≥ grade Ⅱ,1.86,95％ CI 1.19-2.93）.The prevalence of lipodystrophy in d4T group was 19.5％,while that in AZT-substitution group was zero.As to antiretroviral efficacy,these three groups showed no differences.Conclusion AZT-substitution regimen provides a relatively safe and effective first-line antiretroviral strategy in resource-limited settings.     

Association between intervertebral disc degeneration and disturbances of blood supply to the vertebrae

Low back pain is a common public health problem in western industrialized societies and the world as well.Studies indicate that the prevalence rate ranges to 35%, with around 10% of patients from 12% becoming chronically disabled. It also places an enormous economic burden on society. Although the exact cause of low back pain has yet to be defined, intervertebral disc degeneration is considered a major source of it. Since patients with degenerative discs are often asymptomatic, the mechanisms of it are still unclear.

Modulating Effects of Chlorogenic Acid on Lipids and Glucose Metabolism and Expression of Hepatic Peroxisome Proliferator-activated Receptor-α in Golden Hamsters Fed on High Fat Diet

Objective To examine the effects of chlorogenic acid （CGA） on lipid and glucose metabolism under a high dietary fat burden and to explore the possible role of peroxisome proliferator-activated receptor-α （PPAR-α） in these effects. Methods Twenty male golden hamsters were randomly divided into CGA treatment group （n=10, given peritoneal injection of CGA solution prepared with PBS, 80 mg CGA/kg body weight daily）, and control group （n=10, given PBS i.p. at the average volume of the treatment group）. Animals in both groups were given 15% high fat diet. Eight weeks after treatment with CGA, the level of biochemical parameters in fasting serum and tissues and the expression of hepatic mRNA and protein PPAR-α were determined. Results Eight weeks after treatment with CGA, the levels of fasting serum triglyceride （TG）, free fatty acid （FFA）, total cholesterol （TC）, low density lipoprotein cholesterol （LDL-C）, high density lipoprotein cholesterol （HDL-C）, glucose （FSG）, and insulin （FSI） were significantly lower in the GGA treatment group than in the control group. CGA also led to higher activity of hepatic lipase （HL） lower contents of TG and FFA in liver, and lower activity of lipoprotein lipase （LPL） in skeletal muscle. Furthermore, CGA significantly elevated significantly elevated the expression level of mRNA and protein expression in hepatic PPAR-α. Conclusion CGA can modify lipids and glucose metabolism, which may be attributed to PPAR-α facilitated lipid clearance in liver and improved insulin sensitivity.

Current concept in first metatarsophalangeal joint replacement

First metatarsophalangeal joint (MTPJ) degenerative diseases are not rare pathological changes in adult forefoot.1,2 It mainly includes hallux rigidus,hallux limitus and hallux valgus.3 Its progressive nature makes it hardly respond well to conservative treatment.4 Traditional surgical techniques,such as cheilectomy,Keller resection and arthrodesis are effective procedures but remain controversial due to none of them can achieve excellent results in all patients especially the end-stage conditions.5-7 Thus,great amount of efforts have been dedicated in MTPJ replacement despite many negative reports.This technique has aroused many controversies over the past decades due to its prematurity.Nevertheless,it has been improved in many aspects such as prosthesis material,design as well as surgical indications.This review would not only update the advancements and recognitions in recent years,but also presented the major disputed areas.
