In view of the transformation from traditional biomedicine to biology-psychology-social medicine,the comprehensive medical iournals,in order to advance the development of the medicine,should pay attention to the articles on psychology,society and environment with diseases;strictly investigate the ethics in the articles;and publish the articles on the medical humanity promptly.

Objective:To analyze the clinical efficacy and safety of amoxicillin and clavulanate potassium in the treatment of chil-dren with suppurative tonsillitis. Methods:Totally 263 children with suppurative tonsillitis from March 2011 to September 2013 in pe-diatrics were randomly divided into two groups, the control group had 130 cases and the treatment group had 133 cases. All the patients were given conventional treatment, meanwhile, the control group was with intravenous infusion of azithromycin, and the treatment group was orally given amoxicillin and clavulanate potassium dispersible tablets. The clinical efficacy, clinical symptom disappearance time and the incidence of adverse reactions of the two groups were observed. Results:After the treatment, the control group were cured with the total effective rate of 83. 8%, and the treatment group were healed with the total effective rate of 90. 2%. The difference wasn't sig-nificant (P>0. 05). Orally used amoxicillin and clavulanate potassium was more economic and convenient, which could reduce the drug-resistance as well. There was no significant difference in the effects on fever, purulent and the white blood cell between the two groups, and no significant adverse reactions showed in both groups. Conclusion:Orally used amoxicillin and clavulanate potassium ex-hibits obvious therapeutic effect on infantile suppurative tonsillitis, which can effectively improve the clinical symptoms without obvious adverse reactions, and it is worthy of clinical use.

To explore the relationship between the activity of polyol pathway and diabetic microangiopathy, the level of red blood cell sorbitol(RBCS)in 106 patients with NIDDMwas determined. The results indicated that the level of RBCS in diabetic patients was significantly increased, and was positively correlated with 24-h urinary albumin excretion rate(UAER)and the degree of diabetic retinopathy(DR). Besides,the value of RBCS in patients with both pro-teinuris and DR or proteinuria was markedly higher as compared with that in patients with either proteinuria or DR,and the concentration of RBCS in the patients with DR of proteinuria was also significantly higher than those wth neither proteinuria nor DR. In addition.it was also found that the value of RBCS gradually elevated with the aggravation of UAERand DR. These findings suggest that the elevation of RBCS level plays an important role in the formation and development of diabetic microangiopathy.

100% elevation of PKC activity in the retina, and administration of D ? tocopherol prevented the elevation of PKC activity and diabetes induced decrease of both Na + K + ATPase and Ca 2+ ATPase activities. D ? tocopherol achieved a complete prevention of augmented pericyte and endothelial cell profile areas and basement membrane thickening in the superficial and deep capillaries bed of diabetic retina but had no effect on blood glucose and HbA 1c . Conclusion Diabetes induced histopathological abnormalities are mostly mediated by PKC. D ? tocopherol reduces the ultrastructural lesions in retinal capillary bed induced by hyperglycemia.

AIM:To look for a suitable signal peptide which may effectively conduct hepatopoietin(HPO)secretion,various recombinant eukaryotic expression vectors were constructed.METHODS:Different exogenous signal sequences were spliced with HPO cDNA by PCR,and the spliced genes were cloned into eukaryotic expression plasmids.The different recombinants were respectively tansfected into COS-7 cells by Lipofectamine 2000 method and the secretion of HPO was analyzed by Western blotting.RESULTS:Western blotting analysis indicated that the signal peptides from interleukin-1 receptor antagonist(IL-1ra)and an artifical signal peptide did not secret HPO directly and effectively,but the signal peptide from murine Ig kappa secreted HPO directly with great efficiency.The molecular weight of the secreted HPO was 30 kD,which means that the secreted HPO existed in homodimer.CONCLUSION:Secreted recombinant expression plasmid is successful constructed.The result may pave the way for the gene therapy of hepatic fibrosis.

Objective To investigate the clinical efficacy of combined acupuncture and medicine in treating kidney deficiency and phlegm dampness syndrome in obese polycystic ovary syndrome. Method Sixty-four patients were randomly allocated to two groups. The treatment group received combined acupuncture and medicine and the control group, oral administration of metformin. The course of treatment was three months. Pre-treatment and post-treatment indicators were statistically analyzed in the two groups of patients. Result BMI, waist to hip ratio, fasting insulin, fasting blood glucose and HOMA-IR improved significantly in the treatment group of patients after treatment; there were statistically significant pre-/post-treatment differences (P<0.05). Post-treatment BMI and waist to hip ratio improved more markedly in the treatment group than in the control group (P<0.05). Conclusion Combined acupuncture and medicine has a better therapeutic effect on kidney deficiency and phlegm dampness syndrome in obese polycystic ovary syndrome.

Objective To investigate the methods and effects of anterolateral thigh flap reconstruction of the complicated hip decubitus.Methods The study contained 24 cases of grade Ⅳ hip decubitus reconstructed with anterograde pedicled anterolateral thigh flaps through May 2010 to July 2014.There were 13 males and 11 females,aged 26-64 years (mean 54 years).Defects ranged in size from 12 cm×6 cm to 24 cm× 12 cm.Dimensions of flaps harvested were 14 cm ×8 cm to 30 cm× 14 cm.Eighteen cases of the donor sites were directly sutured and six covered with full thickness skin.Results Twenty-two flaps survived completely,and wound was healed by the first intension.Two flaps developed partial distal necrosis,and wound was healed after dressing treatment.Period of follow-up was 6 months to 2 years.Shape,texture and color of the flaps were well matched with the recipient area.Conclusion The anterolateral thigh flap transplantation has advantages of similarity to the recipient area,large enough flap area and sound expected effective and is a good method for repair of hip decubitus.

BACKGROUND:Nanohydroxyapatite/polyamide 66 composite is very close to the human cortical bone in terms of mechanical properties, and has osteogenic activity, which is a safe and reliable bone material. OBJECTIVE:To investigate the effect of nanohydroxyapatite/polyamide 66 composite bioactive supporting material on the restoration of vertebral structure and height. METHODS: Totaly 177 patients with spinal diseases, 116 males and 61 females, aged 17-81 years, were enroled, including 97 cases of spinal fractures, 5 cases of primary tumors of the spine, 17 cases of spinal tuberculosis and 58 cases of cervical spondylosis. The nanohydroxyapatite/polyamide 66 composite bioactive supporting body was filed into the bone grafts of patients and then subjected to anterior decompression and internal fixation. After 36 months of folow-up, imaging analysis, Frankel spinal cord injury classification, bone graft fusion, visual analog scale scores,Short Form 36 and Japanese Orthopedic Association scores were evaluated. RESULTS AND CONCLUSION:During the folow-up, except one patient with cervical spine fracture appeared to have slight supporting body displacement, there was no supporting body prolapse or rupture phenomena. The bone graft fusion rate was 96.0%, the average supporting body sinking distance was 1.7 mm. After treatment, 97 patients with spinal fractures had different degree of improvement in the neurological function (P < 0.05); the visual analog scale scores, Short Form 36 and Japanese Orthopedic Association scores were improved significantly in al the 177 patients compared with before treatment (P < 0.05). These results demonstrate that the use of nanohydroxyapatite/polyamide 66 composite bioactive supporting material for spinal reconstruction can improve the bone fusion rate, and restore the vertebral structure and height effectively.
