ObjectiveTo seek an effective protocol fortreating spinal cord injury-induced limb dysfunction by comparing the therapeutic effects of electroacupuncture at Huatuo jiaji points plus Du meridian points versus conventional electroacupuncture. MethodForty patients with spinal cord injury-induced limb dysfunction were allocated, using a random number table, to treatment and control groups, 20 cases each. Both groups were treated with ganglioside and routine rehabilitation therapy. In addition,the treatment group received electroacupuncture at Huatuo jiaji points and Du meridian points and the control group, conventional acupuncture. Lower limb function was assessed using ASIA Motor Score, Sensory Score and the MBI in the two groups of patients before treatment and after one and two courses. The clinical therapeutic effects were evaluated.ResultThere was a statistically significant pre-/post-treatment difference in lower limb dysfunction in both treatment and control groups (P<0.05). The improving effect was better in the treatment group than in the control group (P<0.05,P<0.01).ConclusionElectroacupuncture at Huatuo jiaji points and Du meridian points has a definite therapeutic effect on spinal cord injury-induced limb dysfunction. It is superior to conventional electroacupuncture.

Impaired glucose tolerance is the prediabetic state of diabetes mellitus,and its main manifestation is postprandial hyperglycemia.Studies in recent years have suggested that the large vascular disease of the impaired glucose tolerance state is similar to diabetes mellitus.The relationship between impaired glucose tolerance and atherosclerotic disease is increasingly receiving attention.This article reviews the relationship between both of them.

Objective To discuss the functional results of percutaneons compressive screw fixation for float injury to the pubic symphysis. Methods From March 2003 to March 2007, 48 cases of float injury to the pubic symphysis were treated with percutaneons compressive screws, including 27 males and 21 females with an average age of 29.4 years. Of them, 39 eases were complicated with injury to the pelvic posterior ring. Emergency surgery was done for 13 cases, 27 cases were operated on within 3 to 7 days after injury and 8 within 7 to 14 days. Guided pins and screws were used during dosed reduction and percutaneous pelvic fixation was done under the guidance of intraoperative fluoroscopic imaging. Float injury to the pubic symphysis was amended by percutaneous fixation after dosed manipulation. Results The average operation time for the48 patients was 55 (31 to 100) min. The intraoperative bleeding averaged 20 to 30 mL. Satisfactory reduetian and fixation was achieved in 41 cases, but 7 cases had poor reduction. All the fractures healed 3 to 6 months postoperatively without infection, nonunion or injury to vessels, nerves or organs. All the patients could turn the body freely in bed the day after operation. Those without injury to the pelvic posterior ring could walk with crutches 3 days after operation. By the Orlando evaluation system for pelvic fractures, 37 eases were rated as excellent, 7 as good, 3 as fair and I as poor. Conclusions The percutaneous compressive screw fixation may decompress the pelvic hematoma, allowing early definitive fixation without the risk of additional hemorrhage. Complications associated with open posterior pelvic surgical procedures may be avoided by using percutaneons techniques.

Objective: To investigate the effects of fibrin glue(FS) and glutamine(Gln) on the healing of colon anastomoses after immediate postoperative intraperitoneal administration of 5-fluorouracil.Methods: Thirty two female Wistar rats were randomized into four groups.After resection of a 1-cm segment of the transverse colon,an end-end sutured anastomosis was performed.Then the rats were divided into control group,5-FU group,FS group,and Gln group.All rats were killed on the 8th postoperative day and the anastomoses were examined microscopically.The bursting pressure measurements were recorded and anastomoses were graded histologically.Results: The adhesion formation score was significantly higer in the rats of the 5-FU group than in the other groups.Bursting pressures were also significantly lower in the 5-FU group than in the other groups.Conclusion: The immediate postoperative intraperitoneal administration of 5-FU inhibited wound healing.However,FS and Gln can improve early healing of colon anastomoses after immediate postoperative intraperitoneal administration of 5-fluorouracil.

Objective To observe the levels of serum hypersensitive C-reaction protein (hs-CRP) and its correlation factors in cerebral infarction patients with impaired glucose tolerance (IGT). Methods According to the result of glucose tolevance test (GTT),the 131 patients were divided into normal glucose tolerance group (NGT, n=41),IGT group (n=47),newly diagnosed type 2 diabetes mellitus (DM) group (n=43). The serum hs-CRP levels and some biochemical parameters were measured in 72 h after the onset. The common carotid artery(CCA) and carotid plaque were examined by color B type ultrasonography. Results The hs-CRP levels were gradually increased among NGT,IGT and DM groups. The average of hs-CRP levels in NGT,IGT and DM groups were 0.320 mg/L,1.435 mg/L,4.305mg/L respectively.By the charge of logaithm,there were significanty differenc among each group(P

[ABSTRACT]OBJETIVETo analyze the reliability and safety of our simplified microsurgical techniques in head and neck reconstruction.METHODSA total of 3045 consecutive cases of free flap transferred in the head and neck region from May 1999 to May 2015 were reviewed. Data concerning the operation included the date of surgery, defect description and site, stage and histology of tumor, type of free flap, recipient vessel and complications.RESULTSOf the 3045 cases, 1856 were males, and 1189 were females. The age ranged from 5 to 86 years, with the average of 47.8 years. Among the 3045 cases, 2868 were tumor-related defects reconstructions, and 2653 were one stage reconstructions. The overall success rate of free flap was 98.5%.

Head and neck reconstruction using this technique is very safe and reliable, and needs further clinical applications.

OBJECTIVE To prepare the Graves disease (GD) mouse model through porcine thyroid globulin (PTG) injection and investigate the morbidity and stability of the model. METHODS C57BL6/N mice in model group received multi-point subcutaneous injection of PTG 25μg each week,six times in all. After the end of immunization,their heart rate and oxygen consumption were measured and serum triiodothyronine(T3)level was determined every two weeks. A model was considered successful if serum T3 level was higher than x+3s of the control group. Observation of the model lasted 12 weeks. At the 12th week,spleen and thymus gland indices,serum thyroid globulin antibodies and thyroid peroxidase antibodies were measured,and the thyroid glands were taken for pathological observation. RESULTS After six times of immunization,mice in model group showed increased heart rate(P<0.01),oxygen consumption(P<0.01)and T3 level(P<0.01)compared with control group. The morbidity was 77.7%for male mice and 88.8%for females. In addition,T3 level in model group remained higher than that in control group within 12 weeks after immunization. The T3 level tended to decrease in male mice,but remained at a relatively stable higher level in females. CONCLUSION This method is suitable for GD modeling due to its short model-making time,high morbidity and long durability.

Background and purpose:Exploration of the effective early diagnostic and prognostic markers of non-small cell lung cancer (NSCLC) has important scientiifc signiifcance and clinical value. Recently, the role of long chain non-coding RNA (lncRNA) in the tumor attracts widespread attention. This study intended to investigate the level of lncRNA HOTTIP in NSCLC, the effect of HOTTIP on cell proliferation and its mechanisms.Methods:Expression of lncRNA HOTTIP in tumor and their matched non-tumor tissues were determined by quantitative real-time PCR (qRT-PCR) in NSCLC patients. Then, we analyzed the potential correlation of lncRNA HOTTIP expression levels in tumor tissues with clinicopathological features of NSCLC and clinical outcome. The effects of HOTTIP on NSCLC cell proliferation and apoptosis were tested usingin vitro MTT and lfow cytometric assays. Western blot method was uesd to detect the expressions of proteins.Results:LncRNA HOTTIP expression level was signiifcantly decreased in NSCLC tissues in comparison to adjacent non-tumor tissues (P<0.05). It was also proved that HOTTIP expression was associat-ed with NSCLC histological grade and lymph node metastasis. Moreover, knockdown of HOTTIP expression in A549 cell line decreased proliferation and enhanced apoptosis compared with transfected negative control. Western blot assay showed that the level of Bax protein was signiifcantly increased, whereas Bcl-2 was signiifcantly decreased in HOT-TIP-silencing A549 cell.Conclusion:HOTTIP is a novel prognostic biomarker and a potential therapeutic candidate forNSCLC.

Objective To identify high affinity ligand MULT1-transgenic mice,analyze its elementary phenotype,and to perform primary functional study in MULT1.Methods We identified the genotype of transgenic mice by PCR and detected transcription level of MULT1 in tails by real-time PCR.The flowcytometry and immunohisto-chemistry were used to analyze the expression of MULT1 in various tissues.Results 25 3'S-strain and 13 4'S-strain MULT1-transgenic mice were obtained and which contain high level of MULT1 transcripts.MULT1 protein is mainly expressed in intestinal intraepithelial lymphocytes (iIELs) and thymocytes but not on splenocytes.Moreover,the levels of MULT1 expression in iIELs and thymocytes are associated with age.Within iIELs,the percentage of CD8~+ Tcells decreased,while CD4~+ CD25~+ Treg cells increased,when compared with wild-type mouse.Conclu-sion We successfully produced MULT1-transgenic mice.MULT1 is possibly associated with thymic development and aging,as well as immunoregulation in mice.

Objective To investigate the role of autophagy in radiation-induced death process of human esophageal squamous carcinoma Eca-109 cells.Methods Esophageal carcinoma cell line Eca-109 was divided into 6 groups of control,5 mmol/L 3-Methyladenine treatment,10 mmol/L treatment,6 Gy irradiation,irradiation + 5 mmol/L drug,and irradiation + 10 mmol/L drug.Some cells were transferred with GFP-LC3 plasmid and the changes of autophagosome were obserred.After each treatment,the expression of autophagy marker LC3B was measured by Western Blot,cell viability was detected by MTT,morphological characteristics of apoptosis cells were stained with a fluorescein of Hoechst 33342 and the percentage of apoptotic cells and cell cycle distribution were measured by flow cytometry.Clonogenic survival were used to evaluate the cell radiosensitivity.Results Autophagy level was increased after radiation,and the LC3B Ⅱ expression and LC3B Ⅱ/LC3B Ⅰ ratio were significantly decreased by autophagy inhibitor 3-Methyladenine (F =25.64,P ＜ 0.05).The number of autophagosome fluorescent foci were significantly increased in the GFP-LC3 transfected cells after radiation,but reduced by 3-Methyladenine (F =127.36,P ＜ 0.05).Compared with radiation alone group,autophagy inhibition combined with radiation significantly decreased cell viability (F =129.54,P ＜ 0.05) and colony formation,increased apoptosis and the percentage of G2/M-phase cells.Conclusions 3-Methyladenine enhances the radiosensitivity of esophageal squamous carcinoma Eca-109 cells,suggesting that inhibition of autophagy could be used as an adjuvant treatment of radiotherapy in esophageal squamous carcinoma.
