BACKGROUND:The currently published literatures about Tuina manipulation for lumbar disc herniation include clinical observations, retrospective study and summary of clinical experience, which have shortcomings in the study design, choice of cases and outcome measures. Reviews may enrol randomized and intended references, and has no analysis or evaluation on the quality of involved literatures, leading to the bias and subjective views.
OBJECTIVE:To research the application laws of Tuina manipulation for treating lumbar disc herniation through literature analysis within 10 years.
METHODS:The key words of“lumbar disc herniation, traditional Chinese medicine, Tuina, manipulation, massage, rehabilitation, poking channels, point pressing, palpating pressing, and finger pressing”in Chinese were used to search the literature about Tuina manipulation in treatment of lumbar disc herniation within recent 10 years published in the Wanfang database, Vip database and CNKI database. The top 20 manipulations of Tuina for lumbar disc herniation were and statistical analyzed with hierarchical clustering statistical method.
RESULTS AND CONCLUSION:The hierarchical clustering analysis results showed that, Tuina manipulations for lumbar disc herniation are as fol ows:(1) manipulations acted on soft tissue, including rol ing, holding, pushing and pressing;(2) manipulations acted on acupuncture point, including Urinary Bladder Meridian of Foot-Taiyang acupuncture points (Shengshu, Dachangshu, Guanyuanshu, Zhibian, Chengfu, Weizhong, Chengshan and Kunlun), Gal Bladder Meridian of Foot-Shaoyang acupuncture points (Huantiao and Yanglingquan), Yaoyangguan point in Du Meridian, Zusanli point in Stomach Meridian of Foot-Yangming, and tender points;(3) manipulations acted on human bones and joints, including waist inclined pul method, waist back-stretching method, pelvic traction method and straight-leg raising method. The findings indicate that the potential application laws of Tuina manipulation for treating lumbar disc herniation are given priority to pressing acupuncture points (Urinary Bladder Meridian of Foot-Taiyang acupuncture point, Gal Bladder Meridian of Foot-Shaoyang acupuncture point, Du Meridian, Stomach Meridian of Foot-Yangming acupuncture point and tender points), at the same time companied with manipulations acted on soft tissue (rol ing, holding, pushing spinal method), and bones and joints (waist inclined pul method, waist back-stretching method, pelvic traction method and straight-leg raising method).

ObjectiveTo identify the correlation factors for urosepsis shock after endourology surgery and analyze its clinical characteristics.MethodsFifty-eight patients with urosepsis without shock and 15 patients with shock were studied.Factors which may be correlated with the development of sepsis were analyzed including age,sex,ASA physical status,history of urinary tract infection,preoperative leukocyturia,urine bacteria culture,prophylactic antimicrobial treatment,pyonephrosis,type of surgery,duration of operation,blood leukocyte count and concentration of creactive protein at the end of surgery,the time when the signs of infection (shivering,agitation,nausea or vomiting) first appeared.Changes in BP in patients with urosepsis shock,scores for multiple organ dysfunction syndrome as well as treatment and prognosis were also recorded.ResultsFemale sex and early emergence of signs of infection after surgery were correlated with urosepsis shock.Abrupt hypotension was usually the first manifestation of urosepsis shook.The lowest systolic BP was positively correlated with the time when diagnosis of shock was made and negatively correlated with the length of ICU stay and the highest multiple organ dysfunction syndrome scores but not correlated with shock correction time.All patients with urosepsis shock recovered completely when discharged from hospital.ConclusionFemale sex and patients with early emergence of signs of infection are prone to develop urosepsis shock after endourology operation.The prognosis of urosepsis shock is good if diagnosed and treated in time.

Objective To investigate the association between IL-22 and the pathogenesis of coronary artery atherosclerosis(AS).Methods The relative expression of IL-22 mRNA in PBMC from 30 AS patients and 8 patients without any signs of coronary artery stenosis was detected by RT-PCR.Serum IL-22 levels of 22 patients without any signs of coronary artery stenosis and 79 AS patients were detected by ELISA.CRL-1730 cells(human umbilical vein endothelial cells) were stimulated with oxidized low density lipoprotein (ox-LDL) at different dosage for 24 h,and the expression of IL-22R1 was detected by flowcytometry.The proliferation ability of CRL-1730 cells treated with IL-22(20 ng/ml) and/or ox-LDL(100 μg/ml)was measured by MTS assay,and the expression of basic fibroblast growth factor(bFGF) was detected by RTPCR and ELISA.Results Decreased IL-22 expression in PBMC and serum was observed as worsen of AS.The expression of IL-22R1 in ox-LDL treated CRL-1730 cells was increased in dose dependent manner.OxLDL decreased proliferation ability,as well as bFGF expression and releasing,of CRL-1730 cells.This effect of ox-LDL was partially rescued by IL-22.Conclusion IL-22 may have anti-atherosclerosis effect.This effect may be mediated by regulating bFGF expression and endothelial cells proliferation ability in the presence of IL-22.

ABSTRACT:Objective To establish a rapid molecular method for the detection of aldehyde dehydrogenase-2 (ALDH2)and investigate the gene polymorphisms of ALDH2?2 and determine whether the polymorphic ALDH2 gene is associated with drinking behavior in a Chinese population.Methods The gene polymorphisms of ALDH2?2 were detected using pyrosequencing,TaqMan Real-time PCR and GeneChip microarray technologies;genotyping of 302 volunteers was performed to assess their genetic associations with alcohol use behavior.Results We developed pyrosequencing,TaqMan Real-time PCR and GeneChip microarray methods to identify ALDH2? 2 polymorphisms.The allele frequency of ALDH2?2 was 20.36% in the Chinese population:16.33% in the alcoholic group and 27.83% in non-drinkers (P=0.001).In contrast,the genotype frequency of heterozygous ALDH2?1/?2 plus homozygous ALDH2?2/?2 was 45.28% in non-drinkers and 32.65% in the alcoholics group (P=0.030). Allele frequency of ALDH2 genotypes differed significantly between our Chinese sample and other ethnic groups in Asia,and it was significantly higher than that in European and American countries.Conclusion The developed pyrosequencing,TaqMan Real-time PCR and GeneChip microarray methods are rapid,accurate,high-throughput, convenient,and reliable for detecting ALDH2 polymorphisms.ALDH2?2 gene can protect against the development of alcoholism.The allele frequency of ALDH2 in this Chinese population differs from that in other ethnic groups.

Objective To observe the clinical curative effect of drug combined with psychological treatment on patients with sleep disorders after stroke.Methods A total of 180 cases of eligible patients with sleep disorders were included and randomly di-vided into control group and treatment group.Control group were treated with conventional vascular drug(estazolam,2 mg,before sleep);treatment group increased anxiolytic and sedative hypnotic drugs(venlafaxine,dexzopiclone)compared to control group.Af-ter 14 days,sleep quality,NIHSS were compared both within the treatment group and between the two groups.Results The Bar-thel index,NIHSS and PSQI of two groups had significant differences,and those index of treatment group before and after treat-ment had significant differences too(P <0.05).Conclusion Combined conventional cerebrovascular drugs with Venlafaxine,dexzo-piclone as well as psychological treatment significantly improved sleep quality of patients with acute stroke.

Objective To investigate the increased expression of microRNA-146a(miR-146a) in peripheral blood mononuclear cells (PBMC) of patients with chronic immune thrombocytopenic purpura (ITP) and its clinical significance. Methods Twenty-eight patients with chronic ITP and 28 healthy controls matched with age and gender were enrolled in this study. Fluorescent quantitative PCR reaction was used to detect the relative expression of miR-146a in their PBMC. The serum concentration of TNF-α, IL-2,IL-1 β and IFN-γ were measured by ELISA. CCK-8 method was used to detect the proliferation ability of PBMC , which transfected with miR-146a mimics or inhibitor and then stimulated with platelet . Results The relative expression of miR-146a in ITP patients was higher than that of healthy controls. The increased expression of miR-146a was negatively correlated with the serum TNF-α, IL-2 and IFN-γ. The PBMC transfected with miR-146a mimics had reduced expression of IL-2 and proliferation when stimulated with platelet.In contrast, the opposite effect was observed with the miR-146a inhibitors transfection. Conclusion MiR146a was involved in the pathogenesis of chronic ITP by controlling IL-2 production and PBMC proliferation.Thus, it may be a potential therapy target for chronic ITP.
