Objective: Investigate the curative effect of acupuncture on dysphasia in hypophrenia children. Methods: One hundred and sixty children with hypophrenia and dysphasia were randomly divided into an acupuncture group of 80 cases, a language training group of 40 cases and a composite group of 40 cases for clinical observation. Total intelligence quotient (TIQ), vocal intelligence quotient (VIQ) and practical intelligence quotient (PIQ) were compared between pretreatment and posttreatment in the children themselves and between the groups before and after treatment. Results: The total efficacy rate was 77.5% in the acupuncture group, 82.5% in the composite group and 52.5% in the language training group. Conclusion: Acupuncture significantly raises TIQ, VIQ and PIQ in the sick children. Language training only raises VIQ to some degree.Acupuncture in cooperation with language training is an effective way to treat this disease.

Objective In many types of epithelial tumors,down-regulation or mutation of the epithelial cell-adherent molecule E-cadherin is associated with an increased invasiveness that can be prevented by the forced expression of the cell-adherent molecule.This suggests that E-cadherin is a latestage tumor suppressor that prevents invasion and metastasis.This study was to investigate cell invasion and migration status of human ovary serous cystadeno carcinoma HO-8910 cell line when the E-cadherin expression was down-regulated with RNA interference(RNAi) technology. Methods E-cadherin siRNA was transfected into HO-8910 cells to inhibit the expression of E-cadherin.The effect of RNAi was detected by immunofluoresence assay and Western blotting.The invasive ability of the cancer cells was determined by Transwell assay. Results After RNAi,the expressions of E-cadherin were significantly decreased from 63.7% to 11.9%(P

Objective To explore the difference in pain threshold between related acupoints and the specificity of acupoints in cholecystitis patients.Method Actual measurement was made in 80cases, a normal group of 30 cases (volunteers without psychological and physiological diseases) and a patient group of 50 cases (volunteers with cholecystitis). The probe of an algometer was perpendicularly placed on the selected acupoint, the pressure point was pushed and pressing was stopped immediately after the subject felt pain. The pain thresholds displayed by the measured acupoints were recorded. The pain thresholds of the selected acupoints were compared between the normal and patient groups and thedifferences were analyzed to explore the specificity of acupoints.Result A comparison of the pain thresholds of the Back-Shu points of the Bladder Meridian of Foot-Taiyang between the patient and normal groups showed that there were no significant differences in the thresholds of the left Back-Shu points Geshu (BL17), Ganshu (BL18), Danshu (BL19), Pishu (BL20), Weishu (BL21) and Dachangshu (BL25) of the bladder meridian between the two groups (P>0.05) and there were significant differences in the thresholds of the right Back-Shu points Geshu, Ganshu, Danshu, Pishu, Weishu and Dachangshu of the bladder meridian between the two groups (P<0.01). The pain threshold was significantly lower in thepatient group than in the normal group. A comparison of the pain thresholds of the main points of the Liver Meridian of Foot-Jueyin, the Gallbladder Meridian of Foot-Shaoyang and the stomach meridian between thepatient and normal groups showed that there were significant differences in the thresholds of the right points Liangmen (ST21), Riyue (GB24) and Qimen (LR14) of the liver, gallbladder and stomach meridians (P<0.01) and no significant difference in the threshold of the right point Taichong (LR3) between the two groups (P>0.05). The pain thresholdwas significantly lower in thepatient group than in the normal group. There were no significant differences in thethresholds of the left points Liangmen, Riyue, Qimen and Taichong of the Liver Meridian of Foot-Jueyin, the Gallbladder Meridian of Foot-Shaoyang and the stomach meridian between the patient and normal groups (P>0.05).Conclusion The pain sensitivity of ipsilaterali related acupoints increase and the relative specificity of acupoints exist in cholecystitis patients.

Background and purpose:Glioblastoma is one of the most common intracranial tumors, the morbidity and mortality are both high, and the molecular biological mechanism of the disease is still unclear. In this study, we detected the gene expression of tyrosine kinase receptor (TKR) pathway in primary glioblastoma(GBM) with low-density array, furthermore we analyzed the significance of the gene expression change. Methods:We detected 26 genes of RTK pathway in 10 primary GBM tissues and 9 normal brain tissues (gained from the decompression operation of brain trauma), and analyzed the different expressions of these two kinds of tissues by statistic method.Results:The Ct values of MAP2K1 and MAP2K4 in normal brain tissues were 1.6?1.7 and 2.2?2.1, the Ct values of MAP2K1 and MAP2K4 in primary GBM tissues were 3.9?1.5 and 5.0?2.0, and the Ct different values between normal brain tissues and primary GBM tissues of both genes were -2.3 and -2.8(P

BACKGROUND: The extramedulary fixation system including dynamic hip screw (DHS) is commonly used in treatment of Intertrochanteric fracture. However, in patients with unstable intertrochanteric fracture, extramedulary fixation system often leads to the failure of fracture fixation. Intramedulary fixation system including both proximal femoral nail antirotation (PFNA) and InterTan nail has been widely used in the treatment of unstable intertrochanteric fractures. OBJECTIVE:To compare the therapeutic effects of extramedulary fixation system containing DHS, PFNA and InterTan nail in the treatment of intertrochanteric fracture. METHODS:Literatures were searched in Wanfang, PubMed, Embase, Medline, the Cochrane library to screen literatures published from January 1990 to November 2014. Relevant studies addressing extramedulary fixation system containing DHS, PFNA and InterTan nail were screened. RESULTS AND CONCLUSION: 346 articles were screened, and 13 of them were in accordance with the inclusion criteria. 1 271 patients with different types of intertrochanteric fracture were assessed in this study. Compared to DHS group, patients treated with PFNA and InterTan nail had shorter operation time and less blood loss. No significant difference in rehabilitation time and Harris score was detected among three kinds of fixation methods. Additionaly, PFNA and InterTan nail had a similar effect. These findings verify that compared with DHS, PFNA and InterTan nail can optimize the surgery, but cannot elevate postoperative outcomes.

BACKGROUND: Previous researches indicate that ADp14ARF transfecting positive tumor cell line of p53 can inhibit the proliferation; in addition, the inhibitory effect is superior to transfection negative tumor cell line of p53. Whether simultaneous transfection of p14ARF and p53 genes can increase expression and accumulation of p53 and accelerate apoptosis of tumor cells needs further studies.OBJECTIVE: To construct double plasmid expression vector plRES-p14ARF-p53 by using gene engineering so as to observe the inhibitory effect on proliferation of osteogenic sarcoma cells.DESIGN: Randomized controlled observation.SETTING: Department of Orthopaedics, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The experiment was carried out in the Public Laboratory Platform, Immune Researching Room, Basic Medical College, Tongji Medical College, Huazhong University of Science and Technology from January 2005 to October 2006. Human osteogenic sarcoma MG-63 cells were provided by Cell Laboratory, Immune Researching Room, Tongji Medical College, Huazhong University of Science and Technology. plRES-p53 plasmid and plRES vector containing p53total-length gene order were provided by Wuhan Jingsai Biology Company.METHODS: Based on gene engineering, p14DNA (0.5 kb) was amplified from cultured L02 cells of normal human hepatic cells into plRES vector. Recombinant plasmid plRES-p14ARF-p53 was determined with polymerase chain reaction (PCR) and restriction enzyme and transfected into human osteogenic sarcoma MG-63 cells through mediation of liposome to screen positive clones. Otherwise, cells were divided into three groups, including blank control group (MG-63cells), blank vector control group (stably transfecting plRES-neo cells) and p14ARF-p53 group (stably transfecting plRES-p14ARF-p53 cells). ① DNA content and cycle of tumor cells were measured by using flow cytometry before and after transfection. ② Reverse transcription polymerase chain reaction (RT-PCR) and Western blot were used to detect quantitative and semi-quantitative expression of p53 and p14ARF protein in tumor cells after stable transfection. ③Thiazole blue chromatometry and growth curve were used to observe proliferation.MAIN OUTCOME MEASURES: ① DNA content and cycle of osteogenic sarcoma cells; ② expressions of p53 and p14ARF protein in tumor cells; ③ proliferation.RESULTS: Double plasmid expression vector plRES-p14ARF-p53 was constructed successfully. ① DNA content and cycle of osteogenic sarcoma cells: Flow cytometry demonstrated that tumor cells mainly stayed in G1 phase after transfection. ② Protein expression: RT-PCR and Western blot indicated that p14ARF and p53 gene independently expressed in target cell mRNA and protein, respectively. ③ Cell growth: At 24, 48, 72 and 96 hours after MG-63 transfection, inhibitory rates of tumor cells were 33.43%, 69.37%, 66.19% and 75.26%, respectively, which was significant difference as compared with blank vector control group (P ＜ 0.01).CONCLUSION: Wild p53 and p14ARF can synergistically inhibit the proliferation and accelerate the apoptosis of osteogenic sarcoma cells.
