This study was to investigate the permeability and absorbability of capsaicin cubosome across abdominal skin of the SD rats in vitro. Diffusion of capsaicin cubosome and cream was performed with the modified Franz diffusion cell technique. The capsaicin cubosome showed no enhancement of skin permeation within 24 hours. However, the deposition amounts of capsaicin in the rat skin in the cubosome group was markedly higher than those in the commercial cream group (P < 0.01). Cubosome showed excellent characetristic of skin-targed which could be a good carrier for the local transdermal drug delivery system.

Objective Retrospectively analyzed the predictive value of imaging evaluation in stage Ⅱ/Ⅲ esophageal carcinoma patients treated with preoperative chemoradiotherapy.Methods A total of 145 stage Ⅱ/Ⅲ esophageal carcinoma pantients were enrolled.We analyzed the overall survival rates of the patients with pathological complete response (pCR) and those without (NpCR),X-film complete response (xCR) and those without (NxCR),RECIST complete response (rCR) and those without (NrCR).And we used Cox model for multivariate analysis.Results The rates of pCR,xCR and rCR were 33.8％,42.8％ and 38.6％ for all patients,respectively.The 1-,3-5-year overall survival rates were 87.8％,79.6％,61.2％ for pCR patients and 75％,40.6％,24.0％ for NpCR patients (x2 =20.215,P ＜0.05),respectively;The 1-,3-5-year overall survival rates were 80.6％,66.1％,51.6％ for xCR patients and 75％,44.6％,25.3％ for NxCR patients(x2 =8.895,P ＜0.05),respectively;The 1-,3-5-year overall survival rates were 83.9％,69.6％,53.6％ for rCR patients and 76.4％,46.1％,25.8％ for NxCR patients(x2 =10.862,P ＜ 0.05),respectively.Multivariate survival analysis using Cox regression model showed that pCR was a positive independent prognostic factor (HR =0.333,95％ CI:0.200-0.554,P ＜ 0.05).Conclusions Short-term imaging evaluation could effectively predict the prognosis of stage Ⅱ/Ⅲ esophageal carcinoma patients treated with preoperative chemoradiotherapy.And pCR was a positive independent prognostic factor.

An analytical method of fluorescent dye-labeled oligonucleotides was established by ion pair reversed phase high performance liquid chromatography(IP-RP-HPLC) which was improved by optimizing the effects of triethylamine-acetic acid(TEAA)(0-0.15 mol/L), pH(4.5-7.0) and gradient. Comparing the retention of 5, 10 and 15-mer unlabeled oligonucleotides with that of 5'-carboxyfluorescein(5'FAM) labeled oligonucleotides, the mechanism of fluorescent dye-labeled oligonucleotides retention was studied. In addition, TaqMan~(TM) probes as wellas other common fluorescent dye-labeled oligonucleotides were concerned. The results showed that the best resolution of different length fluorescent dye-labeled oligonucleotides was observed under the condition of 0.01 mol/L TEAA and pH 7.0. The retention behavior of fluorescent dye-labeled oligonucleotides was different from that of unlabeled oligonucleotides significantly, and therefore they can be separated completely. The results indicated that the retention of unlabeled oligonucleotides enhanced with the increase of the length of molecule. In contrast, the retention of fluorescent dye-labeled oligonucleotides was reduced with the increase of the length of molecule. For the hydrophobicity of fluorescent dyes made a great impact on the retention, a longer retention time the labeled oligonucleotides would take while the hydrophobicity of fluorescent dyes was higher. However, the effect of the hydrophobicity was limited as the length was increased to a certain level.

Objective To study the expression and pathologic significance of CD147,cyclophilin A (CyPA)and cyclophilin B(CyPB)in psoriatic lesions.Methods Immunohistochemical method was ap- plied to detect the expression of CD147,CyPA and CyPB in skin specimens of 15 patients with psoriasis pustulosa(PP),20 patients with progressive psoriasis vulgaris(PPV),and 20 patients with inactive psori- asis vulgaris(IPV).Immunoreactivity intensity distribution index(IRIDI)was calculated to assess the expres- sion intensity of CD147,CyPA and CyPB.Results CD147,CyPA and CyPB were detected in all speci- mens.The IRIDI scores of CD147 and CyPA were significantly higher in keratinocytes of psoriatic lesions than in those of the control specimens(all P0.05).The IRIDI score of CyPB in T lymphocytes of PP lesions was significantly elevated than that in PPV lesions,which was in turn higher than that in IPV lesions(all P0.05).Conclusion CD147,CyPA and CyPB may play a role in the occurrence and development of psoriasis.

Objective To observe the results and reality of transurethral resection of bladder tumor(TUR-Bt) with upside down loop and plsamakinetic in the prevention of obturator nerve reflex.Methods A total of 211 patients with lumbar anesthesia received TUR-Bt.Firstly,the tumor tower above bladder wall was cut with the traditional way.When intraoperative findings were obturator nerve reflex,or to the obturator nerve mapping area,operation should be changed to superimpulse plasma column electrode vaporization to cut off residual tumor tissue,then after flipping the loop,the residual tumour was resected with upside-down loop from the tumour side wall.Results In 211 cases,192 cases had a little obturator nerve reflex,but the movement of body was not obvious,which did not influence the operation.The serious complication,such as perforation of bladder and injury of nerve and vessel,did not occur.Conclusions The lateral resection of bladder side wall tumour with upside-down loop can effectively avoid strong obturator nerve reflex,which is safe,uncomplicated,and efficacious and it does not increase the additional outlay and hurt.

Objective To investigate the correlation ofClaudin-1, Ki-67 and CD34 expressionsin the tumor tissue to the invasiveness, grading and proliferation of astrocytic tumors. Methods In 50cases of astrocytic tumor, the expressions of Claudin-1, IO-67 and CD34 were detectedimmunohistochemically in the tumor tissue, normal brain tissues and in the junctional area between thetumor and normal tissues. The expressions of Claudin-1, Ki-67, and CD34 were analyzed in relation tothe clinicopathoiogical characteristics of the patients. Results The expression rate of Claudin-1 was70.59% in the astrocytic tumors of histological grades Ⅰ and Ⅱ, significantly higher than that in grade Ⅲand Ⅳ tumors (9.09%, χ2=20.206, P=0.000). In grade Ⅲ and Ⅳ tumors, the positivity rates of Ki-67 inthe normal tissues, junctional area and the tumor tissue were all significantly higher those in grade Ⅲ andⅣ tumors (t=9.144, 5.958, and 6.297; P=0.000, 0.000, and 0.000, respectively). Grade Ⅲ and Ⅳ tumorsdisplayed significantly greater mierovessel density (MVD) than grade Ⅰ and Ⅱ tumors in the tumor tissue(t=3.101, P=0.003) and the junctional area (t=4.139, P=0.000). In all the tumors, significantly higherKi-67 expression was seen in the tumor tissue (12.74±6.93) than in the junctional area (7.42±3.93) andthe normal tissue (3.22±1.57) (F=51.726, P=0.000), and the MVD was also greater in the tumor tissue(27.48±8.26) than in the junctional area (10.72±3.93) and normal tissue (6.48±1.45) (F=215.538, P=0.000).Conclusion Expressions of Claudin-1, Ki-67, and CD34 are closely correlated to the proliferation andinvasion of astrocytic tumors, and these cytokines may serve as important indicators for evaluating themalignancy of astrocytic tumors..

ObjectiveTo investigate and compare the prevalence,awareness and risk factors of chronic kidney disease (CKD) between urban and rural population in Guangxi province in order to provide information for prevention and treatment of CKD.MethodsBy a stratified multistage random sampling method,18 to 74 years old residents in Guangxi province were surveyed. They wereevaluatedbyquestionnaire,urinaryalbumin/creatinineratio, hematuria (microscopic examination of centrifuged urine sediment),kidney B-mode ultrasound,and abnormal results were reviewed 3 months later.Estimated glomerular filtration rate(eGFR) was calculated with the simplified MDRD equation modified by a Chinese coefficient.The risk factors associated with CKD were also investigated.Results There were no significant differences between urban and rural residents in the prevalence of albuminuria (5.22％ vs 5.47％) and hematuria (1.07％ vs 1.11％)(all P＞0.05).The prevalence of renal lithiasis in rural residents was significantly higher than that in the town(10.54％ vs 6.95％)(P＜0.05).The decreased renal function between urban and rural residents(3.87％ vs 4.04％,P＞0.05) had no significant difference.The prevalence of CKD was 9.58％ in urban and 9.42％ in rural(P＞0.05).The prevalence of albuminuria according to the age distribution was different between urban and rural,which increased along with the age in urban but showed two peaks(30-40 years old and 60-74 years old) in rural.Based on logistic regression analysis,the risk factors for albuminuria were diabetes,hyperuricemia,the history of cardiovascular disease,chronic tonsillitis and HBsAg positive.The risk factors for kidney function decline were age,hyperuricemia,hypertension,diabetes,renal lithiasis and history of cardiovascular disease.The awareness rate of CKD in urban was significantly higher than that in rural (14.45％ vs 6.27％,P＜0.05).Conclusions The prevalenceof CKD has no significant difference between urban and rural in Guangxi province.The awareness rate of CKD in urban is significantly higher than that in rural.It is needed to enhance the prevention and treatment of CKD in rural.
