Objective To observe the effect of heat-producing needling (Shao Shan Huo) and cool-inducing needling (Tou Tian Liang) on the gait cycle after operation for gluteus contracture. Method Sixty-six patients after operation for gluteus contracture were randomized into a treatment group and a control group, 33 in each group. The control group was intervened by rehabilitation, while the treatment group was by acupuncture in addition to the rehabilitation training. The topical points Zhibian (BL 54), Huantiao (GB 30), and Juliao (GB 29) were treated with reducing cool-inducing needling technique; Biguan (ST 31), Futu (ST 32), Zusanli (ST 36), Fenglong (ST 40), Xuehai (SP 10), Diji (SP 8), and Yanglingquan (GB 34) were treated with reinforcing heat-producing needling technique. The motor time parameters were observed before and after intervention.Result After intervention, the supporting phase of the affected side, supporting phase of the healthy side, gait cycle, swinging phase of the affected side, swinging phase of the healthy side, and bilateral supporting phase of the treatment group were significantly different from that of the control group (P<0.05).Conclusion Heat-producing and cool-inducing needling techniques can effectively shorten the gait cycle after operation for gluteus contracture, and can improve the walk function.

Objective To study the influence of artesunate (Akt) on the proliferation and apoptosis of human head and neck squamous cell carcinoma (HNSCC), and to explore its molecular mechanism thereof. Methods The HNSCC cell line,UM-SCC-10A cells, was cultured in vitro. The Inhibitory concentration 50 (IC50) was examined by MTT assay. The cell mor?phological changes were observed under inverted light micro-scope after being interfered by 0, 2.5, 5, 10, 20 and 40μmol/L Akt. Cell cycle changes and apoptosis were measured by flow cytometry. And the expression of cell cycle regulators and apop?totic associated protein were detected by Western blot assay. Results MTT assay demonstrated that Akt significantly inhib?ited the proliferation of UM-SCC-10A cells in dose-dependent manner. After UM-SCC-10A cells were treated with Akt for 48 h, IC50 was 15.01μmol/L. Morphological changes of cell apoptosis such as karyopyknosis and conglomeration were ob?served by Hoechst 33258 staining. Flow cytometry showed that the apoptosis was associated with cell cycle arrest during the G1 phase. Western blot analysis showed that p53 and p21 protein was up-regulated and Cyclin D protein was down-regulat?ed. Furthermore, results revealed that Bcl-2 associated X protein induced by a mitochondrial pathway, cytochrome C and caspase-3 were up-regulated, and Bcl-2 and procaspase-3 were down-regulated. The mitochondrial membrane potential was reduced. Conclusion Artesunate can induce apoptosis of UM-SCC-10A cells via a mitochondrial pathway, which was associated with cell cycle arrest in the G1 phase. As a result, artesunate has an obvious inhibitory effects on proliferation of UM-SCC-10A cells.

Long non-coding RNAs (lncRNAs) are a group of regulatory and non-coding RNA molecules which are longer than 200 nucleotides. They are involved in a variety of biological processes such as cell proliferation, differentiation and apoptosis mainly by regulation of gene expression at various levels, including epigenetics, transcription and post-transcription. The evidence has demonstrated that many lncRNAs are dysregulated and closely related to tumorigenesis, progression and prognosis in gastric cancer. Based on an introduction to lncRNAs and the domestic and foreign research status, this review summarizes the function, regulatory mechanisms, potential diagnostic and therapeutic values of lncRNAs in gastric cancer.

Through the excellent experiment of cardiovascular system in pathology, the prac-tice of the teaching reform was carried out such as combining flow model with real specimens, digital sections with light microscope slides, inserting the use of special staining experiments in combination with digital medical image analysis and the simulation of cardiovascular clinical pathological case dis-cussions. Linking theory with experiment teaching and experiment teaching with clinical practice was focused on, which not only stimulated students' interest in learning and their exploring thinking and hands-on ability, but also promoted them to obtain good learning effect, thus improving the teaching quality.

Objective To evaluate the predictors of maternal and fetal outcome of pregnancy for systemic lupus erythematosus(SLE)patients.MethodsNinety-four patients with 96 pregnancies which were evaluated retrospectively from Jan 1990 to Jan 2008 in Peking Union Medicai College Hospital were divided into two groups:disease stable during pregnancy(group A)and lupus flares during pregnancy (group B).Statistical analysis was performed by X2 or Fisher exact test and Student's t-test.A binary logistic regression model was used to evaluate the predictors of matemal and fetal outcome.Results There were 36 pregnancies with stable lupus disease(group A)and 60 pregnancies with lupus flares(group B).of the 96 pregnancies.18 resulted in therapeutic abortion and 7 in fetal loss,71 resulted in a live birth,3 in neonatal death.The rates of preterm delivery,small gestational age(SGA)and neonatal asphyxia in group B were higher than those in group A(P＜0.05).By binary logistic regression analysis,preeclampsia/eclampsia low serum platelet count and SLE flares were associated with poor fetal outcome(β=2.463,2.228.2.769 respectively.P＜0.05).,rhere were 56 pregnancies with stable lupus disease at the conception with 22(39.3%)occurred lupus flares during pregnancies.Twenty-four preeclampsia and 2 eclampsia were seen in all the pregnancies.Fifty-two pregnancies were complicated with lupus nephritis,and 25 pregnancies(48.1%,25/52)of which were disease stable at the conception,and among 22 pregnancies with disease stable over one year.twelve of which occurred lupus nephritis flares.Three pregnancies which have disease activity within one year before pregnancy all occurred lupus nephritis flares.There were four maternal death which all occurred at the postpartum.By binary logistic regression analysis,lupus nephritis flares were associated with preeclampsia/eclampsia(B=2.658,P＜0.05),and proteinuria at the conception before dilivery were significantly associated with SLE flares(13=3.263,P＜0.05).Conclusion An increase of fetal loss,preterm delivery,SGA and neonatal asphyxia was seen in patients with lupus flares during pregnancy compared with those with stable disease.About 1/3 lupus activity may increase after pregnancy.Preeclampsia and eclampsia were increased when there were lupus nephritis flares.

Objective To obtain more information concerning polymorphism of the thyrotropin (TSHR) in Graves diseases(GD). Methods (1)A family of GD was studied (including 3 patients and 9 healthy family members)to examine SNPs of TSHR through direct sequencing of all 10 exons and part of introns. (2)In the current case-control study, 30 patients with familiar GD, 48 sporadic patients and 96 healthy control individuals were used to assess whether SNP of TSHR was associated with GD. Genomic DNA was extracted from peripheral leukocytes isolated from ACD-anticoagulated blood. Ten exons were amplified by PCR, using primers designed by ourselves. After purifying, the products were sequenced. Results Eight polymorphisms were found. There was a novel polymorphism in exon 8. There were no significant differences between patients and controls. Conclusions These findings suggested that the novel and other polymorphisms of the TSHR gene may not be responsible for GD. There are racial differences in the distribution of polymorphisms of TSHR gene.
