Objective To explore the relationship between quality of life and sub-health state of Guangdong urban dwellers.Methods A total of 2 200 urban dwellers were investigated using SF-36 and Sub-Heahh Measurement Scale Version 1.0(SHMS V1.0).Results As for the scores in PCS,MCS,psychosocial symptom,cognitive function,social adaptability,those of man urban dwellers (respectively (78.89± 15.25),(73.15 ± 15.26),(63.73± 18.82),(62.13± 19.34),(68.04± 17.90)) were higher than those of woman dwellers (respectively(76.98± 14.20),(71.76± 14.72),(60.53± 18.28),(57.00± 17.89),(65.73± 17.07)).The difference was statistically significant (P＜0.05).Bivariate correlation analysis showed that the PCS and MCS of quality of life were positively related with all dimensions of sub-health (P＜0.001).Canonical correlation analysis indicated that vitality,social adaptability,psychosocial symptom and positive emotion were the main factors of sub-health status,and MCS was of quality of life.Conclusion Sub-health state of Guangdong urban dwellers is positively related with quality of life,and the more serious sub-health state is,the worse quality of life is.Therefore,intervention of subhealth and quality of life should be targeted to be strengthened according to the investigation.

Objective To explore causes of complications after endovenous laser treatment (EVLT) , for patients with superficial varicosities of the lower extremities. Methods In this study, 207 patients with a total of 268 lower limbs were treated by EVLT combined with surgical procedures. According to CEAP classification, there were C2 in 268 limbs, C3 in 56 limbs, C4 in 101, C5 in 23 and C6 in 18. Simple EVLT was performed for 25 limbs in 21 patients; EVLT combined with external banding valvuloplasty of superficial femoral vein for 23 limbs in 23 patients; EVLT combined with ligation of great saphenous vein (CSV) and denudation of superficial varicosities for 220 limbs in 163 patients. Results An average of 10?5 (3-24) months of follow up was achieved in 175 cases. Early complications (within the first 2-weeks after operation) included bruising or ecchymosis (178 cases, 66.42%) and skin burning (56, 20.90% ). Three month complication included painful induration or trabs (235 cases, 87. 69% ) as well as thrombophlebitis (28, 10. 45% ). Long-term complication (after 3 months) included skin numbness or pain at medial knee or ankle region (15,5. 60% ). Recanalization of CSV occurred in 4( 1. 49% ) treated limbs. Residual or reoccurred varicose veins were found in 13(4. 85% ) cases. Movement related swelling appeared in 6(2. 24% ) lower limbs. Conclusion EVLT is effective for patients with superficial varicosities of the lower extremities. Minor complications most often subsided within 3 months. Strict surgical protocol and high ligation of the GSV could prevent local recurrence of the varicose veins and the recanalization of GSV.

Objective Cervical radiculopathy treatment experts' consensus to establish radiculopathy type by using the modified Delphi method. Methods Use document retrieval method to review information and articles about the treatment guidelines and articles of cervical radiculopathy including domestic and international areas, established a protocol about clini?cal consensus of the treatments for cervical radiculopathy. This protocol included 23 questions (the effective proportion of non?operating therapy, neck immobilization, physiotherapy, pharmacologic treatment, surgical indications, contraindications, anteri?or surgical decompression, anterior surgical implants). We performed a modified Delphi survey in which current professional opinions from experienced experts, representing from almost all of the Chinese provinces, were gathered. And then we modi?fied the protocol according to those professional opinions. Three rounds were performed and finally we established consensus. Consensus was achieved with ≥70% agreement. Results The panel included 30 experienced experts. The recycling question?naire's quantity of three rounds were 30(100%), 24(80%) and 16(53.3%) respectively. After three expert assessments, there were 18 questions which achieved with≥70%agreement and these questions accounted for 64.3%(18/28) of all the questions. Consen?sus of the treatments for cervical radiculopathy was reached on 7 aspects, including:the effective proportion of non?operating thera?py (1 question), neck immobilization (1 question), physiotherapy (1 question), pharmacologic treatment (5 questions), surgical indi?cations (3 questions), contraindications (4 questions), surgery (3 questions). Conclusion This modified Delphi study had reached a consensus concerning several treatment issues on cervical radiculopathy which had strong representativeness of experts and good convergence of opinions. In the absence of high?level evidence, at present, these experts' opinion findings will guide health care providers to define appropriate treatment in their regions. Areas with no consensus provide excellent insight for future research.

Objective To investigate the status of soil fertility of Good Agricultural Practices ( GAP) base for Spatholobus suberectus Dunn. (SSD) in Pingyuan county of Guangdong province, thus to provide reference for GAP research and the subsequent fertilization for SSD. Methods The deep layer and superficial layer of GAP soil were collected for the physiochemical detection and nutrient assay. Compared with the classification standard of the second national general soil investigation, single base soil fertility index was diagnosed and the comprehensive soil fertility was evaluated with modified Nemoro Index. Results The soil pH value and the contents of exchangeable calcium and magnesium were unbalanced, and the contents of macroelements of nitrogen and phosphonium, microelements, and organic matter were low. Therefore, the measures for improving the base soil fertility should be as follows: ( 1) soil amendments of bentonite, gypsum and slaked lime should be used to adjust the soil pH value; ( 2) each plant should be given 10 kg of slaked organic fertilizer as base fertilizer; ( 3) in the process of nurturing, some special micro-fertilizer solution should be used to treat the cut slips, and 5 kg of urea should be used for every 667 meter square of land; ( 4) besides compound fertilizer, every 667 meter square of land should be fertilized with 15 kg of ammonium dihydrogen phosphate for the supplement of nitrogen and phosphorus, and slaked lime and magnesium carbonate should be used for the supplement of soil moderate-quantity elements after transplantation. Conclusion The comprehensive fertility of Pingyuan GAP base for Spatholobus suberectus Dunn. is at low level, and should be improved in combination with GAP requirements.

In previous study, the 150-ku oxygen-regulated protein(ORP150) was identified as a candidate glycoprotein related to hepatocellular carcinoma.In order to further validate the expression level of ORP150 in hepatocellular carcinoma, protein expression was determined by Western blot and cell immunochemistry, and messenger RNA(mRNA) expression was detected by quantitative real-time polymerase chain reaction.The effect of ORP150 on apoptosis and invasive potential of hepatocellular carcinoma cells was evaluated using the small interference RNA(siRNA) technique.Both the protein and mRNA expression levels of ORP150 were significantly upregulated in hepatocellular carcinoma cell lines compared with a non-tumor human liver cell line.After transfection with the specific siRNA of ORP150, significantly greater apoptosis of hepatocellular carcinoma cells was induced compared with untransfected cells.However, no significant effect on invasive potential was found.Overexpression of ORP150 was associated with hepatocellular carcinoma, and ORP150 might promote the proliferation of hepatocellular carcinoma cells by inhibiting apoptosis.ORP150 could be a potential therapeutic target for hepatocellular carcinoma.
