Calponin is an actin filament-associated regulatory protein expressed in smooth muscle and many types ofnonmuscle cells.Three calponin isoforms 1,2,and 3 are encoded by three homologous genes CNN1,CNN2 and CNN3 in vertebrate species with cell type-specific expression and functions.Besides modulating the activity of smooth muscle myofilaments and contractility,calponin also regulates the functions of actin cytoskeleton in non-muscle cells during cell proliferation,adhesion,migration,differentiation,phagocytosis and fusion.This review focuses on the evolution,tissue and cell type-specific expression,structure-function relationships,transcriptional regulation and relevant mechanisms.

4cm) or involved the urethra、 vagina、 clitoris or anus. Pathologic grouping was 25 squamous carcinomas 3 adenocarcinomas and 2 undifferentiated carcinomas. Radiotherapy was given by angled radiation with wedge block. Dose was 65 to 70 Gy/6-7W. RESULTS Thirty patients completed their inductive chemotherapy within 30 days for 86 courses. The response rate was 86. 7% (26/30). CR was 30. 16%. 18 of 30 patients were followed-up for over 5 years. Five years survival rate was 72.2 (13/18). Major acute complications were vuvitis (23%). Late adverse effects were 1 patient with ure-throstenotic uroschesis, 1 patient with pathologic transcervical fracture. None of patients had radiation rectitis and cystitis. CONCLUSION Inductive chemotherapy consisting of modified VBP regimen was active in reducing the vulvar tumor volume. Radiotherapy used angled radiation with wedged block to treat advance vulvar cancer was fa-ciliated. Chemoradiotherapy was found to be an effective treatment for locally advanced vulvar carcinoma, with acceptable morbidity even in an elderly population. The technique allowed maintenance of normal anatomical and physiologic function that would have been compromised by primary surgical approach. It yielded survival rates comparable to those achieved with ultraradical surgery in younger patients. Life quality was improved significant-ly.

AIM:To study the correlation of serum uric acid ( UA) level with carotid plaques and arterial stiff-ness in the patients with essential hypertension ( EH) , and to explore the predictive value of serum UA for evaluating EH preclinically .METHODS:A total of 92 patients with EH and 30 healthy individuals were enrolled .The value of UA and other indicators were detected .B-mode ultrasound examination was performed to measure the common carotid artery intima -media thickness ( IMT) and the sites of plaque in the internal carotid-artery, external carotid artery and carotid bifurca-tions.Carotid-femoral arterial pulse wave velocity ( CFPWV) was assessed by Complior?atherosclerosis measurement in-strument.RESULTS:The serum level of UA in the patients with EH was higher than that in control group [(361.51 ± 83.81) μmol/L vs (317.03 ±62.22) μmol/L, P<0.05].The mean value and abnormal rate of IMT between hyperten-sion group and control group were significant difference [(0.69 ±0.14) mm vs (0.60 ±0.12) mm, 42.39%vs 10.00%, P<0.05].In 92 EH patients, 45 cases had carotid plaques .These 45 cases were divided into 3 groups according to the plaque severity, among which the serum UA level had statistically significant differences [(285.25 ±78.41) μmol/L, (341.19 ±63.99) μmol/L and (401.33 ±88.49) μmol/L, P<0.05].Compared with rigid plaque group ( n=34), the serum UA level in soft plaque group (n=11) was significantly higher [(389.00 ±69.45) μmol/L vs (323.03 ± 72.71) μmol/L, P<0.05].A stepwise multiple linear regression analysis demonstrated that age ( r=0.414), systolic blood pressure (r=0.224), pulse pressure (r=0.270) and uric acid (r=0.219) were predisposed factors for higher CFP-WV (P<0.05).CONCLUSION:UA is one of the risk factors causing hypertension .Serum UA level may reflect the sever-ity and stability of carotid plaques .The increased arterial stiffness is closely related to the increased serum UA level in EH .

AIM: To study the effect of genistein on c-myc mRNA expression induced by oxidized low density lipoprotein (ox-LDL) in human vascular endothelial cells (ECV304). METHODS: LDL were isolated from healthy human plasma by gradient ultracentrifugation and oxidized by CuSO4. ECV304 cells were exposed to ox-LDL 200 mg*L-1 in the presence or absence of genistein 100 μmol*L-1 for 1, 2, and 4 h in vitro. Northern blot was employed to measure c-myc mRNA levels of ECV304. RESULTS: In response to ox-LDL 200 mg*L-1, c-myc mRNA expression in ECV304 increased by 3 fold for 1h and 3.3 fold for 2 h and decreased below the control level at 4 h. Expressions of c-myc stimulated by ox-LDL in the presence of genistein 100 μmol*L-1 for 1 h and 2 h were separately 80 percent and 60 percent of that in the absence of genistein 100 μmol*L-1. CONCLUSION: Genistein can effectively inhibit c-myc mRNA expression in ECV304 induced by ox-LDL.

Objective To investigate the effects of C-terminal fragment of parathyroid hormonerelated protein (PTHrP107-139) on bone mineral density (BMD), bone histomorphometry and biomechanical properties in ovariectomized (OVX) rats and its effect on bone metabolism is also explored. Methods Forty 4-month old female Wistar rats in which 30 were ovariectomized and then divided into 3 groups: the placebo, the PTHrPC and the CT groups, the other 10 rats were Sham-operated as the control group (Sham). Five weeks later, the rats of PTHrPC and CT groups were subcutaneously injected with PTHrP107-139 (40 μg/kg) and Salmon Calcitonin (15 U/kg) respectively once every other day. The rats of the placebo and sham groups were injected with 0.2 ml saline once every other day. After treatment of 12 weeks, all rats were sacrificed and all samples were collected and analyzed. Results ① Compared with the placebo, the BMD and bone strength of PTHrPC and CT groups were significantly increased (P<0.05). ② Histomorphometry revealed that the tetracycline labeled bone surfaces, osteoid surfaces, mineral apposition rate and bone resorption rate were remarkably decreased in PTHrPC, and CT groups comparing with those of the placebo group. Conclusion Cter-minal PTHrP107-139 is effective in increasing the BMD, bone strength and quality when administered intermittently to ovariectomy-induced osteoporotic rats. Its increasing in bone quality may relate to reducing bone turnover and inhibiting resorption.

Objective To examine the levels of fractional exhaled nitric oxide in bronchial asthma and the cor-relation between fractional exhaled nitric oxide and pulmonary function tests as well as the value of pulmonary function tests in curing the children with bronchial asthma. Methods Seventy - two asthmatic children came from Guiyang Ma-ternal and Child Health Hospital were studied. They were divided into 2 groups:mild - to - moderate asthma group(36 cases)and serious asthma group(36 cases). Fractional exhaled nitric oxide level and the lung function were measured and the correlation analysis was analyzed by SPSS 13. 0 software. Results The fractional exhaled nitric oxide concen-tration of the serious asthma group was significantly higher than that of the mild - to - moderate asthma group[(47 ± 26)ppb vs(29 ± 15)ppb,t = 3. 543,P ﹤ 0. 01],1 - second rate,maximum mid - expiratory flow(MMEF),and peak expiratory flow(PEF)in mild - to - moderate asthma group were significantly higher than those in serious asthma group[(99. 74 ± 9. 81)% vs(87. 17 ± 13. 30)% ,(87. 12 ± 35. 61)% vs(68. 90 ± 30. 88)% ,(99. 97 ± 10. 83)% vs (94. 31 ± 17. 69)% ](P ﹤ 0. 01,0. 05,0. 05). No correlations were found between fractional exhaled nitric oxide level and the lung function parameters,including forced expiratory volume in 1s(FEV1),1 - second rate,MMEF and PEF in the mild - to - moderate asthma group(r = 0. 073,0. 087,0. 242,0. 326,all P ﹥ 0. 05). However the level of fractional exhaled nitric oxide was negatively correlated with the lung function parameters,including FEV1,FEV1 / FVC,MMEF and PEF in serious asthma group(r = - 0. 354,- 0. 573,- 0. 478,- 0. 471,P ﹤ 0. 05,0. 001,0. 005,0. 005),respec-tively. Conclusions Monitoring of fractional exhaled nitric oxide and the lung function parameters can effectively indi-cate the state of illness of asthmatic child,which plays a key role in the treatment.

Objective investigate the correlation between plasma soluble receptor for advanced glycation endproducts (sRAGE) and arterial stiffness in patients with different types of metabolic syndrome (MS).Methods A total of 180 subjects were drawn from a epidemiologic follow-up study,including 60 cases non-metabolic syndrome (NMS),60 cases metabolic syndrome without diabetes mellitus (NDMMS),60 cases metabolic syndrome with diabetes mellitus (DMMS).Carotid femoral arterial pulse wave velocity (CFPWV) was assessed by the French KangPuLe atherosclerosis measurement instrument,and plasma sRAGE levels were measured by ELISA.Comparison of mean in multiple groups was conducted by analysis of variance.Multivariate analysis was done with multiple linear stepwise regression analysis.P ＜ 0.05 was considered as statistically significant difference.Results Compared with NMS group,plasma sRAGE levels were significantly lower in DMMS and NDMMS groups [(635.07 ± 229.20) pg/mL vs.(671.17 ± 358.16) pg/mL vs.(992.99 ± 427.83) pg/mL,P =0.001].CFPWV of DMMS group was significantly higher than that of NMDMS and NMS groups (14.22 ±3.14) m/s vs.(12.15 ±2.79) m/s vs.(11.66 ± 2.52) m/s,P =0.002).Plasma sRAGE level was negatively correlated with CFPWV (r =-0.278,P =0.005).(3) Multiple linear regression analysis demonstrated that age (β =-0.091,95％ CI-0.096 ～-0.095,P =0.031),HDL-C (β =1.295,95％ CI 1.231 ～ 1.360,P =0.022) and sRAGE (β =0.119,95％ CI 0.118 ～ 0.130,P =0.032) had a significant effect on CFPWV.Conclusions The increased arterial stiffness is closely related to the discreased plasma sRAGE levels in MS.Plasma sRAGE maybe a novel target for vascular disease prevention and treatment in patients with metabolic syndrome.
