Objective To explore the interactive effect of acupuncture and exercise on severe traumatic brain injury (TBI). Methods 120 comatose patients following TBI after routine surgery were equally divided into combined group (acupuncture and exercise), acupuncture group, exercise group, and control group (neither acupuncture, nor exercise). They were assessed with Glasgow coma scale (GCS),Fugl-Meyer assessment (FMA), modified Brathel index (MBI) and neurological deficit scores (modified Edinburgh-Scandinavia stroke scale, MESSS) before and after the treatment. Results The scores of GCS, FMA, MESSS and MBI improved more in the combined group than in the control group (P<0.05). The scores of GCS and MESSS improved more in the acupuncture group and the exercise group than in the control group (P<0.05). The scores of MESSS improved more in the combined group than in the exercise group (P<0.01). Conclusion Both acupuncture and exercise can synergetically reduce the disability and coma of comatose patients following TBI.

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.

Objective To investigate the clinical features of acute traumatic subdural hematomas (SDH) in infants and discuss the treatment methods. Methods The clinical features of 48 infants under three years old with acute traumatic SDH admitted from 2002 to 2008 were retrospectively analyzed.Results There were 31 infants under one year old (65%). The most popular injury cause was accidental fall in 37 patients (77%). Of all patients, 12 patients (25%) had disturbance of consciousness,eight ( 17% ) had convulsion and eight ( 17% ) were combined with skull fractures. The treatment methods included craniotomy and evacuation of the blood clot in 18 patients ( including 13 patients underwent instant operation after admission ), burr hole craniotomy and external drainage of the chronic subdural hematoma in seven and conservative management in 23 with small subdural hematomas. All patients obtained good outcome except that two patients had motor dysfunction and one death. Conclusions The incidence of acute traumatic SDH in infants is high, especially in infants under one year old. It is easy to be disregarded at early stage and may deteriorate to chronic subdural hematoma or hydropsy. Early diagnosis and active surgical treatment may attain sound prognosis.

Objective To study the role and clinical significance of chemokine receptor-4 (CXCR4) and vascular endothelial growth factor (VEGF) in the occurrence and development of renal cell carcinoma. Methods Expression of CXCR4 and VEGF were detected by SP immunohistochemical technique in 56 cases of kidney carcinoma tissues (including 20 cases of lymph node metastasis), 10 normal tissues nearby kidney cancer. Results The positive rates of CXCR4 and VEGF were 66. 1% (37/56) and 73. 2% (41/56),which were significantly higher than those in normal tissues( 20. 0% (2/10) and 30. 0% (3/10), respectively) (P ＜ 0. 05 ＝. The expression of CXCR4 protein was significantly positively correlated with that of VEGF protein (r = 0. 315 ,P ＜ 0.05 ＝ in renal cell carcinoma. The expression of CXCR4 and VEGF was closely related to stages of tumor ( χ2 = 9. 520, P = 0. 023; χ2 = 9. 072, P = 0. 027 ), lymphatic metastasis, degree of invasion ( χ2 =4. 972, P = 0. 026; χ2 = 3.910, P = 0. 034 ), and microvessel density ( MVD) ( P ＜ 0. 05 ＝. However, they were not related to sex ( χ2 = 0. 020, P= 0. 887; χ2 = 0. 001, P = 0. 716 ), tumor size ( χ2 = 0. 003, P = 0. 995; χ2 =0. 108, P = 0. 990) and pathologic types ( χ2 = 1. 960, P = 0. 900; χ2 = 0. 112, P = 0. 994). Conclusion There is a significant positive correlation between high expressions of CXCR4 and VEGF proteins in renal cell carcinoma,the high expressions of CXCR4 and VEGF proteins may be related to the metastasis and prognosis of renal cell carcinoma,thus they could be used as important indicators in judging the metastasis prognosis of renal cell carcinoma,and offer prospects for the treatment of renal cell carcinona.

METHODS Eighty eight liver transplantation recipients with HBV-related end-stage liver diseases including chronic fulminant hepatitis B,end-stage liver cirrhosis and liver carcinoma were analyzed retrospectively,and were given lamivudine pre-transplantation to prevent hepatitis B virus reinfection.Post-transplantation medicines of lamivudine were administered in 3 cases;lamivudine and hepatitis B immunoglobulin(HBIg) in 85 cases.The follow-up criteria included serum HBV,HBV-DNA,liver biopsy,immunohistochemical study of liver biopsy specimens and clinical manifestations.All of patients were followed-up 6 months at least.RESULTS Two of the three cases who taken lamivudine developed reinfection,the little time is 6 months following liver transplantation.There were three of eighty five cases taken lamicudine and HBIg(small dosage) developed reinfection.CONCLUSIONS Liver transplantation is an effective treatment for HBV-related end-stage liver diseases.Given lamivudine at the pre-transplantation could reduce the levels of the HBV virus copies.Lamivudine and HBIg post-transplantation offer effective prevention against hepatitis B virus reinfection.

Objective To investigate the influence of long non-coding RNA HOTAIR in proliferation and apoptosis of human tongue squamous cell carcinoma in vitro and in vivo. Methods siHOTAIR was used to inhibit the HOTAIR expression in Tb3.1 human tongue squamous cell carcinoma cell line. The experiments were divided into siHOTAIR group, nonsense sequence group and blank control group. Real-time PCR was used to detect the HOTAIR expression. MTT assay was employed to determine the cell survival. The expression levels of Bcl2, BAX, caspase-3, cleaved caspase-3 were examined by Western blot assay. Tb3.1 xenograft tumor model was established in BALB/c nude mice, and the tumor model was divided into control group, negative group, and siHOTAIR treated group. The tumor tissues were measured by immunohistochemistry stain (IHC) and TUNEL assay. Results The detection of real-time PCR showed that HOTAIR expression was reduced after treated with siHOTAIR. Western blots assay showed that Bcl-2 protein was suppressed while cleaved caspase-3 and BAX protein were up-regulated after treated with siHOTAIR. MTT assay indicated that the cell survival rate was significantly reduced in siHOTAIR treated group. Flow cytometry detected that apoptosis levels were increased in siHOTAIR group. The level of cell senescence was higher in the siHOTAIR group than that of control group. Results of IHC indicated that Ki-67 and Bcl-2 protein of tumor tissue were inhibited, while BAX and cleaved caspase-3protein expressions were elevated simultaneously in the siHOTAIR group. TUNEL assay suggested that more apoptosis was observed in siHOTAIR group. Conclusion HOTAIR can affect proliferation and apoptosis of tongue squamous cancer cells. HOTAIR may be one of the new candidate targets for human tongue cancer therapy.

Objective To investigate the effect of signal transducers and activators of transcription 3(STAT-3)on sen-sitizing oral squamous cell carcinoma to cis-dichlorodiamineplatinum via downregulating miRNA-21. Methods Tscca and Tca8113P160 human tongue squamous cell carcinoma cell lines were employed in this study. WP1066 was used to suppress STAT-3 signaling pathway. Cells were divided into three groups:dimethyl sulphoxide (DMSO) group, cis-dichlorodiamine-platinum (DDP) group and WP1066+DDP group. Transcription level of miR-21 was assessed by real-time PCR, while the expression levels of STAT-3, p-STAT-3, tissue inhibitor of metalloproteinase-3 (TIMP-3) and matrix metalloproteinase-2/9 (MMP-2/9 ) were evaluated by Western blot assay. Matrigel matrix and transwell assay were used to determine cancer cell colony formation and invasive ability respectively. Expression level of miR-21 was examined by luciferase reporter gene as-say. Results Expression levels of STAT-3, pSTAT-3 and miR-21 were significantly suppressed by WP1066 treatment. The diameters of culture colony in cells treated with WP1066 and DDP were smaller than those in control group. The number of tongue cancer cells that migrated through the transwell membrane in WP1066 and DDP treated group was less than that in control group. Additionally, MMP-2/9 expression decreased while TIMP-3 increased dramatically in both cell lines in WP1066+DPP group compared to the other two groups. Conclusion Reduction of STAT-3 can sensitize oral squamous cell carcinoma to cis-dichlorodiamineplatinum via downregulating miR-21. Our study shows that DDP, in combination with WP1066, might be used as a potential target in the treatment of human oral squamous cell cancer.

Objective To investigate effectiveness of anthropometric parameters and body composition analysis for the screening and prediction of metabolic syndrome and explore the best indicator for predicting metabolic syndrome in the elderly. Method A cross-sectional study of 763 (406 men and 357 women) elderly people who participated in the annual health check-up was conducted. Clinical data of all participants were obtained including anthropometric parameters, body composition, lipid profiles, fasting blood glucose, and high sensitivity C-reactive protein. Receiver operating characteristic (ROC) curve was used to determine the optimal cutoff points for waist circumference, waist-to-hip ratio, waist-to-height ratio, percent body fat and fat mass index in relation to the area under the curve (AUC), sensitivity and specificity in the screening and prediction of metabolic syndrome. Result In total subjects, compared with non-metabolic syndrome group,the ROC curve analysis showed that parameters including waist circumference, waist-to-height ratio, waist-to-hip ratio, percent body fat and fat mass index had a significant potential for predicting metabolic syndrome (P<0.001). It was determined that waist circumference of 87.5 cm and 77.5 cm, waist-to-hip ratio of 0.89 and 0.87, waist-to-height ratio of 0.51 and 0.52, percent body fat of 24.1%and 31.7%and fat mass index of 5.00 kg/m2 and 7.80 kg/m2 were the optimal cutoff points for screening and predicting the presence of metabolic syndrome among men and women with a sensitivity of 81.3%,78.8%,87.5%, 51.3%and 83.8%(in men) and 85.1%,79.8%,71.3%, 70.2%and 80.9%(in women) and a specificity of 57.7%,62.6%,50.0%, 75.5%and 51.8%(in men) and 38.0%,53.2%,55.1%, 50.6%and 52.5% (in women),respectively. The area under the ROC curve (AUC) was 0.728, 0.755, 0.716, 0.671 and 0.725 in men and 0.652, 0.707, 0.658, 0.619 and 0.675 in women,respectively. Waist-to-hip ratio showed the highest AUC in all the parameters in men and women. Conclusion Anthropometric parameters and body composition analysis play important roles in the screening and prediction of metabolic syndrome, and waist-to-hip ratio seems to be the best parameter in the screening and prediction of metabolic syndrome in the elderly.
