Objective To compare the efficacies of intralesional hyaluronidase(HAase), intralesional dexamethasone(DEX), and intralesional HAase plus intralesional DEX on skin damage caused by vinorelbine extravasation in a rat model. Methods After establishing an animal model with vinorelbine extravasation in each lower extremity of 40 Sprague-Dawley rats, we treated the rats with intralesional HAase,intralesional DEX, intralesional HAase plus intralesional DEX,intralesional saline,or received no treatment as control.The wound area on 1 d, 4 d, 8 d, 12 d, 18 d, 24 d, 30 d and the time of healing were observed and compared.Results The wound area on 1 d, 4 d, 8 d, 12 d, 18 d and 24 d was significantly lower in intralesional HAase group, intralesional DEX group,intralesional HAase plus intralesional DEX group,and intralesional saline group than that in control group (P ＜0.05), and that was significantly lower in intralesional HAase group and intralesional HAase plus intralesional DEX group than that in intralesional DEX group and intralesional saline group (P ＜0.05). The healing time was significantly shorter in 4 therapy groups than that in control group [(25.1±3.1) d, (27.9±2.8) d, (23.0±3.2) d, and (28.4±3.9) d vs.(31.2±3.0) d, P ＜0.05], and that was significantly lower in intralesional HAase group and intralesional HAase plus intralesional DEX group than that in intralesional DEX group and intralesional saline group (P ＜0.05). Conclusion The monotherapy with intralesional HAase or intralesional DEX, with decreasing the extent of skin damage and shortening the healing time, is effective therapy for skin damage caused by vinorelbine extravasation, and the monotherapy with intralesional Haase is more efficacious. The efficacy of intralesional HAase plus intralesional DEX seems better than that of monotherapy.

Objective To comparatively investigate the adhesive capabilities of sodium alginate and guar gum as bone adhesives.Methods The adhesive capabilities were analysed and discussed by measuring their kinetic viscosities,solidification time and the reaction with calcium ions.Results Guar gum had higher kinetic viscosity and could fit to the supply of both ion calcium and non-ion calcium for the bone cure,but its capability of solidification need to be improved.Sodium alginate had higher solubility and its solidification could be finished in short time,but it had lower viscosity and fit only to the non-ion calcium supply.Conclusion Sodium alginate and guar gum are considered to be the potential natural materials of the bone adhesives.

Objective To discuss the clinical characteristics for central compartment lymph node metastasis in stage cNO papillary thyroid microcarcinoma and significance and feasibility of preventive dissection,aimed to provide reference for clinical treatment.Methods Reviewed the clinical data of 277 patients with stage cNO papillary thyroid microcarcinoma from Jul.2011 to Dec.2015 underwent surgery in the Department of General Surgery of Lianyungang East Hospital.Evaluated the necessity of prophylactic central lymph node dissection.Adopted chi square test and Logistic regression to analyze its relationship with patients' gender,age,tumor number,tumor size,enveloped infiltration,single and bilateral tumor.All 277 patients underwent primary radical resection with ipsilateral central lymph node dissection.The specimen of resection was analyzed by routine pathology.Results The positive rate of thyroid papillary microcarcinoma lymph node metastasis was 36.8 ％ (102/277).The elements of male patients (P =0.023),age ＜ 45 years (P ＜ 0.001) and tumor diameter ＞ 0.5 cm (P =0.019)had high positive rate.The multivariable analysis showed that male patients (OR =2.63,P ＜ 0.001),age ＜ 45 years (OR =2.25,P =0.016),tumor diameter ＞ 0.5 c m (OR =2.13,P =O.009) were independent risk factors for CLN metastasis.Forty-three (15.5％) cases had transient parathyroid function.No Permanent recurrent nerve paralysis and hyperparathyroidism occurred in this group.Conclusions Prophylactic central lymph node dissection is helpful for accurate staging of tumor classification and risk assessment,has important significance,on the follow-up of patients after treatment of choice.For male patients,age ＜ 45,tumor diameter ＞ 0.5 cm,enveloped infiltration,the central compartment lymph node dissection may be necessary.

Objective To further improve the accuracy of bone age identification using the time of secondary ossification center appearance and epiphyseal fusion of 7 joints to estimate the age of living individuals.Methods DR films were taken from 7 parts including sternal end of clavical and the left side of shoulder,elbow,carpal,hip,knee and ankle joints of 1709 individuals who came from eastern China,central China and southern China,whose ages were between 11.0 and 20.0 years.From those 7 joints 24 osteal loci were selected as bone age indexes,which could better reflect age growth of teenagers.The characteristics of secondary ossification center appearance and epiphyseal fusion were observed,and the mean and age range of secondary ossification center appearance and epiphyseal fusion were calculated.Results The fusion time of the 24 epiphyses were advanced at different degrees,the most obvious epiphyses the sternal end of clavicle,scapular acromial end,distal end of the radius,distal end of the ulna,iliac crest,ischial tuberosity,the upper and lower end of tibia and fibula.The appearance time of sternal end of clavicle,scapular acromial end,iliac crest and ischial tuberosity epiphyses were all found to be after the age of 12,and the female's age,approximately 1year ahead of schedule in comparison with the male's.Conclusion The relevant forensic information and data for bone age identification should be updated every 10-15 years so as to provide accurate and objective evidence for court testimony,conviction and sentencing.

Objective To investigate the implication of C-reactive protein in development and prognosis of acute lower limb deep venous thrombosis (DVT) complicated by malignant tumor.Methods34patients with acute lower limb DVT complicated by malignant tumor(observation group),34 patients with acute lower limb DVT complicated by operation or wound(case control group)and 34 normal volunteers (normal control group) were included in this study.The observation group and case control group were treated with conventional therapy such as thrombolysis and anticoagulation.The serum concentrations of CRP before treatment and 14 days after treatment were detected. Recanalization of lower limb DVT and therapeutic efficacy were compared between observation group and case control group.ResultsThe serum concentrations of CRP in observation group before treatment were significantly higher than those in case control group and normal control group [(47.72±29.88) mg/L vs (30.04±15.84) mg/L and (6.19±2.99) mg/L,F =38.444,P ＜ 0.01].At the 14th day of post-treatment,the serum CRP concentrations in observation group and case control group were significantly lower than those before treatment (P ＜0.05).At the 14th day of post-treatment,the CRP concentrations of observation group and case control groups were significantly decreased,although those of observation group were still significantly higher than those of case control group and normal control [(32.77±19.68) mg/L vs (7.76±7.52) mg/L and (6.19±2.99) mg/L,F =50.087,P ＜ 0.01].However,there was no significant difference between case control group and normal control group on the 14th day of post-treatment (F =1.277,P =0.263).The recanalization rate of observation group at the 14th day of post-treatruent were significantly lower than those in case control group(x2 =7.731,P =0.021).The therapeutic effect rate of observation group at the 14th day of post-treatment were also significantly lower than those in case control group (x2 =6.969,P =0.031).ConclusionCRP may play important roles in occurrence,development and therapeutic effect of acute lower limb DVT complicated by malignant tumor.
