Objective To evaluate the relationship between glycemic control and lipid profile in patients with type 2 diabetes.Methods The patients with type 2 diabetes taking oral antidiabetic agents only were investigated for their levels of blood glucose and lipid profile.With a standard for valid blood glucose control( HbA1c ＜7％ ),the patients were divided into two groups,reached the goal group and not reached the goal group,and the lipid profile was compared between the two groups.Results Completed study had been obtained 173 patients,average HbAlc,7.9％,total success rate of glycemic control,with 43.4％ being the figure reported.We can see a lower triglyceride( TG),total cholesterol (TC) and low density lipoprotein cholesterol(LDL-C) level and a higher high density lipoprotein cholesterol (HDL-C) level in the group reaching the stantard ( t =- 2.437,- 2.067,2.005,- 2.984,P =0.016,0.040,0.047,0.003).Conclusion The blood lipid profile should be considered while the level of glucose of patients with type 2 diabetes taking oral antidiabetic agents alone are controlled.

Objective To study the modulation effect of adrenomedullin (ADM) on hypoxia pulmonary hypertension in rats.Methods Twenty-four male Wistar rats were randomly divided into control group ( n =8), hypoxic group ( n =8), hypoxic with ADM group ( n =8). ADM was subcutaneously administered into rats of hypoxic with ADM group by mini-osmotic pump (300 ng/h). After two weeks hypoxic challenge, systolic pulmonary arterial pressure (sPAP) and mean pulmonary arterial pressure (mPAP) were evaluated by a right cardiac catheterization procedure. Mean systemic artery pressure (mSAP) was measured. The ratio of right ventricular mass to left ventricular plus septal mass [RV/(LV+S)] was detected.Results sPAP, mPAP and RV/(LV+S) significantly increased in hypoxic rats compared with controls ( P

Objective To discuss the predictive value of multiple ultrasonic features combination in diagnosis of thyroid papillary carcinoma (PTC) more than 1.0 cm in diameter. Methods The ultrasonic features of 258 PTC nodules from 251 patients and 207 nodular goiter (NG) nodules from 190 patients in the First People′s Hospital of Hangzhou were retrospectively analyzed. All the nodules were confirmed by pathological examination after surgery. The ultrasonic features included the shape of nodules, internal echo,anteroposterior/transverse diameter ratio (A/T), and microcalcification. The χ2 test was used to analyze the differences of ultrasonic features between PTC and NG. Multi-variate analyses (Logistic regression) was used to analyze the predictive risk ultrasonic features of PTC. The sensitivity and specificity of ultrasonic features were analyzed based on the gold standard of pathological results. Results There were significantly differences between 258 PTC nodules and 207 NG nodules in irregular shape, hypoechogenicity,A/T > 1 and microcalcification (χ2 values were 121.511, 105.411, 41.483, 121.072, all P < 0.01). The results of Logistic regression showed that irregular shape, hypoechogenicity, A/T>1 and microcalcification were risk ultrasonic features of PTC. And their OR values were 5.013 (95%CI 2.919-8.610), 5.811 (95%CI 3.411-9.901), 15.399 (95%CI 7.576-31.301), 4.141 (95%CI 1.687-10.164) respectively. The sensitivity and specificity of single ultrasonic feature were 26.0%-79.5% and 71.5%-96.1%; the sensitivity and specificity of two ultrasonographic features combination were 11.2%-57.0% and 92.3%-99.0%; and the sensitivity and specificity of three or four ultrasonographic features combination were 8.1%-31.8% and 99.0%-99.5%.Conclusions Irregular shape, hypoechogenicity, A/T> 1 and microcalcification of thyroid neoplasm are important ultrasonic features of PTC. Although the sensitivity of single ultrasonic feature in diagnosing PTC is higher than that of multiple features combination, it has a lower specificity. Therefore, combination of multiple ultrasonographic features can improve the specificity in diagnosing PTC and reduce the misdiagnosis of PTC.

Objective To explore the relationship between dynamic changes in ultra-micro-structural of pulmonary arteries and endogenous hydrogen sulfide in rats with left-right shunt.Methods Rats in shunt group were subjected to an abdominal aorta-inferior vena cava shunt to create an animal model of pulmonary artery structural remodeling. After 1 day, 3 days, 1 week, 4 weeks and 8 weeks of experiment, the ultra-micro-morphologic changes of pulmonary arteries of rats were observed under electronic microscope and H_2S concentration in serum was evaluated by modified sulfide electrode method.Results The changes of ultra-micro-structure of pulmonary arteries were progressively exacerbated, endothelial cells became swollen and large in size on 3 days, smooth muscular cells increased in size as well as the change of endothelial cells in 1 week, and they changed from contractile phenotype to synthetic phenotype in 4 weeks.Conclusions Shunt exhibited changes of ultra-micro-structure of pulmonary arteries are accompanied by the changes of endogenous H_2S. It is suggested that endogenous H_2S might play a protective role in changes of ultra-micro-structure of pulmonary artery.

OBJECTIVETo investigate how network education can improve college students' knowledge on sexual and reproductive health in Ningbo city.

METHODSFrom December 2012 to June 2013, we conducted a questionnaire investigation among college students in Ningbo city about the effects of network education on their knowledge about sexual psychology, sexual physiology, sexual ethics, and reproductive health.

RESULTSA total of 7 362 college students accomplished the investigation, of whom 2 483 (42.1% males and 57.9% females) received network education, while the other 4 879 (24.1% males and 75.9% females) did not. Approximately 47.1% of the male and 28.0% of the female students acquired sexual and reproductive knowledge via network education. Reproductive health-related network education significantly enriched the students' knowledge about the reproductive system and sex, pubertal development, sexual physiology, conception and embryonic development, methods of contraception, sexual psychology, sexually transmitted diseases and their prevention, pregnancy care and eugenics, and environment- and occupation-related reproductive health (P < 0.01). It also remarkably improved their cognitive attitude towards reproductive health knowledge (P < 0.01). Those who received reproductive health-related network education showed a significantly higher rate of masturbation (P < 0.01) but markedly later time of the first masturbation (P < 0.01) than those who did not.

CONCLUSIONNetwork education can enhance the effect of reproductive health education among college students and improve their sexual experience and health.

The present study was undertaken to define whether intracarotid injection of capsaicin induces Fos expression associated with the activation of NOS-containing neurons in brainstem nuclei by combining the immunocytochemical method for Fos with NADPH-d histochemical technique for NOS. The results obtained are as follows: (1) Intracarotid injection of capsaicin caused a significant increase of Fos-like immunoreactive neurons in area postrema (AP), nucleus tractus solitarius (NTS), paragigantocellularis lateralis (PGL) and locus coeruleus (LC), without influence upon the neurons of raphe nuclei (RN) and periaqueductal gray (PAG). (2) NO-containing neurons in PGL and NTS and the double-labeled neurons in PGL were also increased significantly following intracarotid injection of capsaicin. Small numbers of NO-containing neurons were found in LC, but there was no change in the number of NO-containing neurons in RN and PAG. No NADPH-d histochemical activity could be found in AP. (3) The above responses to capsaicin were significantly inhibited by pretreatment with either a capsaicin receptor antagonist ruthenium red or a NMDA receptor antagonist MK-801. The above results indicate that intracarotid injection of capsaicin may activate the neurons in brainstem nuclei involved in cardiovascular regulation, and that NO only plays an indirect role in the modulation of the responses of brainstem nuclei to capsaicin. These effects of capsaicin are mediated by capsaicin receptors with involvement of glutamate.

OBJECTIVETo summarize the therapeutic effect of multiple types of posterior interosseous artery flaps for repair of soft tissue defects in the upper extremities.

METHODSFrom March 2003 to June 2010, 42 cases with soft tissue defects in the upper limbs resulting from burn and traumatic injuries were treated using multiple types of posterior interosseous artery flaps, including retrograde flaps and composite flaps, antegrade flaps ,and free flaps. Flap size ranged from 2.5 cm x 2.0 cm-14.0 cm x 9.0 cm. The defects in the donor sites were closed directly or covered by skin graft.

RESULTSThe conventional retrograde posterior interosseous artery flaps were used in 11 cases, the modified retrograde posterior interosseous artery flaps were used in 13 cases, the retrograde posterior interosseous artery composite flaps incorporating partial extensors were used in 2 cases, the antegrade posterior interosseous artery flaps were used in 3 cases, the free posterior interosseous artery flaps were used in 7 cases, and the free perforator flap based on the radiodorsal septocutaneous perforator of the posterior interosseous artery were used in 6 cases. Partial necrosis happened in one case at the distal portion of the flap. Muscular branch of the posterior interosseous nerve was injured in one case with conventional reverse posterior interosseous artery flaps. All the other flaps survived uneventually with no complication. All wounds were primarily healed. 32 cases were followed up for 1 to 48 months with satisfactory aesthetic and functional results both in the donor sites and in the recipient areas. The color,texture and thickness of the flaps were satisfied as well.

CONCLUSIONSThe posterior interosseous artery flap has a constant vascular anatomy and a great flexibility, which is practical and suitable for repair of Soft tissue defect in the upper extremities arising from burn and traumatic injury.

This study was aimed to investigate the effect of advanced glycosylation end products (AGE) on the proliferation of K562 and K562/A02 cells, the effect of tetrandrine (Tet) on proliferation of K562 and K562/A02 cells induced by AGE, and their mechanisms. The effects of AGE on proliferation of K562 and K562/A02 cells and Tet on the proliferation of AGE-induced K562 and K562/A02 cells were assayed by CCK8 kit, the apoptosis rate and the expression of receptor of advanced glycosylation end products (RAGE) in K562 and K562/A02 cells were determined by flow cytometry, the expression of RAGE mRNA was detected by semi-quantitative RT-PCR. The results showed that AGE could promote the proliferation of K562 and K562/A02 cells in a concentration-dependent manner, the cell proliferation was enhanced with time increasing in 0 - 48 h, and was higher than control group after 72 h. AGE up-regulated the RAGE mRNA and protein expressions of K562 and K562/A02 cells in a concentration-dependent manner. Treatment of Tet combined with AGE for 48 h could inhibit the proliferation of K562 and K562/A02 cells promoted by AGE in a concentration-dependent manner, which probably by inducing cell apoptosis, however, there was no obvious effect in the up-regulating expression of RAGE mRNA and protein induced by AGE. It is concluded that AGE can promote the proliferation of K562 and K562/A02 cells, which is probably induced by up-regulating the expression of RAGE mRNA and protein. Tet can inhibit the proliferation of K562 and K562/A02 cells induced by AGE, and the mechanism may be not closely associated with changes of the up-regulating expression of RAGE mRNA and protein induced by AGE.
