Objective To explore the role of Annexin Ⅱ and urokinase-type plasminogen activator(uPA) proteins in the development and lymph node metastasis of thyroid cancer.Methods Immunohistochemistry was used to detect the expression of Annexin Ⅱ and uPA proteins in 35 cases of papillary thyroid cancer tissues,10 cases of thyroid adenoma tissues,16 cases of nodular goiter tissues and 7 cases of normal thyroid tissues.Results The positive expression rate of Annexin Ⅱ and uPA protein was significantly higher in papillary thyroid cancer than in normal thyroid tissues,nodular goiter tissues and thyroid adenoma tissues( P ＜0.05 ).The expression of Annexin Ⅱ and uPA protein was positively correlated in papillary thyroid cancer tissues(P ＜0.05).The expression of Annexin Ⅱ protein in thyroid cancer tissues was associated with tumor size and lymph node metastasis while the expression of uPA protein was only related to lymph node metastasis.Conclusions Annexin Ⅱ and uPA proteins are involved in the occurrence and development of papillary thyroid cancer.They also play a facilitating role in lymph node metastasis of papillary thyroid cancer.

ObjectiveTo investigate the cause,diagnosis and treatment measures of neonatal pneumothorax.MethodsThe clinical data of 98 cases with neonatal pneumothorax in our hospital from Mar 2005 to Mar 2010 were reviewed retrospectively.ResultsThere were 27 premature neonates and 71 full-term neonates in the 98 cases.Ten cases were spontaneous pneumothorax and 88 cases were non spontaneous pneumothorax.After the treatnent of primary disease,pleural aspiration,chest drainage and mechanical ventilation,88 cases were cured,8 cases were improved and 2 cases died.ConclusionNeonatal pneumothorax is related with cesarean section,improper use of endotracheal intubation,meconium aspiration,premature hyaline membrane disease using pulmonary surfactant and ventilator therapy.Most pneumothorax is due to lung disease.The prevention of preterm birth and asphyxia can reduce the incidence of neonatal pneumothorax.

In this experiment, the HPLC specific chromatogram was adopted, with Agilent Extend-C18 (4.6 mm x 250 mm, 5 microm) as the chromatographic column, and 0.5 per thousand trifluoroacetic acid and acetonitrile as the mobile phase for gradient elution, so as to establish specific chromatograms for drug pair of Schizonepetae Herba and Saposhnikoviae Radix from different producing area, identify 12 common characteristic peaks, and obtain the comparison specific chromatography of drug pair of Schizonepetae Herba and Saposhnikoviae Radix. The method is simple, accurate and highly reproducible, and thus can be used as the basis for the quality control of the drug pair.

Objective To explore the relationship between the expression of P53 protein and the radiosensitivity in patients with advanced maxillary squamous cell carcinoma.Methods An immunohistochomical method wag used to detect the expression of P53 protein in patients with advanced maxillary squamous cell carcinoma.The follow up time was 2 years.The local recurrence of the patients having been treated with radical surgery and affiliated radiotheraphy were analyzed.Results The overexpression of P53 protein in 26 cages was 65.4% (17/26).In the P53 overexpression group,the local recurrence after systiem therapy wag occurred in one case within 6 months,6 cages between 7～12 months.3 cages between 13～18 months and 2 cases between 19～24 months.In the P53 low expression group,there were no recurrence within 6 and 12 months and one case ocurred within 18 months.5 cages between 19～24 months.The difference of recurrence within 18 months after system therapy between the expression of P53 Wag statistically significant(P＜0.05),but it Wag not significant for those within 24 months(P＞0.05).Conclusions The expression of P53 protein Wag correlated with the radiosensitivity in patient with advaneed maxillary squamous cell carciaoma,especially for the resid.rod cells in mitosis phase.The affiliated radiotherapy after radical surgery Wag limited effect.

Objective To investigate an association between Toll-like receptor(TLR)4 Asp299Gly or CD14 C-260T polymorphisms and colorectal cancer in Chinese patients.Methods By a method of polymerase chain reaction-based restriction fragment length polymorphism(PCR-RFLP), TLR4 Asp299Gly and CD14 C-260T polymorphisms in unrelated 110 patients with colorectal cancer and 160 healthy controls in Chinese Han race population were genotyped.Results Significant differences of CD14 genotypes were found between healthy controls and the patients with colorectal cancer.The fre- quency of the CC genotype in healthy controls was extremely lower than that in the group of colorectal cancer(15.6% vs.31.8%,P=0.0027,OR=0.3968,95%CI:0.2209-0.7129)while the frequency of the CT genotype in healthy controls was significantly higher than that in the group of colorectal cancer (48.1% vs.30.9%,P=0.0056,OR=2.074,95%CI:1.246-3.452).No TLR4 Asp299Gly mutant genotype was detected in any patients and healthy controls in Chinese Han population.Conclusion The polymorphism of CD14 C-260T but not TLR4 Asp299Gly is associated with colorectal cancer in Chinese patients.

Objective To assess the renal protective effects of triptolide treatment in type 2 diabetic rats and its possible mechanisms.Methods Wistar rats were randomized to receive following approach control (n=7),dia- betic model without treatment (n=7) and diabetic group treated with triptolide[200 ?g/(kg?d),n=7].Plasma glucose (PG),serum creatinine (Scr),total cholesterin (TC),triglyeride (TG),kidney mass (KM),index number of kidney hypertrophy (KM/body mass,KM/BM),and 24 hours urinary albumin (24 h UAL) were determined. The protein expression of monocyte chemoattractant protein-1 (MCP-1),osteopontin (OPN) and ED-1 in renal tissue were determined by immunohistochemical technique.The mRNA expressions of MCP-1 and OPN in kidney tissue were assessed by reverse transcription-polymerase chain reaction (RT-PCR).Results Elevated 24 h UAL was markedly attenuated by triptolide treatment [24 h UAL,triptolide:2.32?0.29 vs diabetic model group:3.89? 0.51 mg/mgCr,P

Aim To screen alteration in protein level in brain tissue between middle cererbral artery occlusion(MCAO) and the total saponins of Rubus Parviflolius L(TSRP) treated rats and to learn the mechanism of nerve-protecting effects of TSRP after focal cerebral ischemia-reperfusion.Methods The MCAO 2 h reperfusion of 24 h model was established in rats,2-DE was applied to preparein step 1 for the separation of protein,and imaging analysis of gels was done with Image-Master 2D software.Different protein spots expressing between cerebral ischemic reperfusion(CIR) model and TSRP group were cut from the gels for the MS analysis,Different protein spots expressing between cerebral ischemic tissue administered with or without TSRP were also cut from the gels for the MS analysis.MALDI-TOF-MS and database search: protein spots from step 2 were subject to in-gel digestion and MALDI-TOF-MS analysis,which resulted in the peptide mass fingerprint spectra(PMF).PMF were search against swiss-prot database using search program of Ms-Fit.Results By comparative proteome analysis,29 expression-altered spots were excised for MS and informatics analysis,comparing to the CIR model,18 proteins up-regulated in the TSRP group,11 proteins down-regulated,7 spots of them were identified and characterized.Conclusion The protective effect of TSRP on cerebral ischemia-reperfusion is the result of the participation of a number of proteins.

Aim To establish a model of focal cerebral ischemic tissue of rat brain and explore the injury mechanism of focal cerebral ischemia reperfusion in whole level of proteins.Method The model was established with suture method by reperfusion 24 h after ischemic 2 h according to Koizumi′s method,total brain tissue proteins were extracted with Lysis buffer,proteins were separated by two-dimensional electrophoresis(2-DE),stained by Coomassie brilliant blue,the patterns were gotten,differential proteins were found out,PMS was obtained by MALDI-TOF-MS,and related information of proteins was gained by MS-Fit database.Results A comparative proteomic study of model and normal group was performed.Compared with model group,the normal group gained 23 differential protein spots,13 spots expressed lowly,and 10 spots high,6 protein spots were identified,the relative cerebral ischemic proteins such as Leukotriene A-4 hydrolase,Thyrotropin-releasing hormone-degrading ectoenzyme etc were found out.Conclusions Establishing a 2-DE technology is applied to protein analysis of brain tissue,and the relative proteins of cerebral ischemia are found from proteome aspect.This will contribute to the research on the injury mechanism of cerebral ischemic tissues.
