This study examined the effect of GHRP-6, a known GHSs receptor agonist, on the phosphorylation of cAMP-responsive element-binding protein (CREB) and the underly mechanism. GH3 cells were cultured and subjected to different treatments as follows: GHRP-6, GHRP-6 plus GHRH, phorbol ester (PMA), an activator of PKC, alone or in combination with GHRP-6, Gö6983, a general inhibitor of PKCs, in the presence or absence of GHRP-6, rottlerin, an inhibitor of PKCs, alone or plus GHRP-6. The cells were transiently transfected with PKCsigma-specific siRNA and then treated with GHRP-6. GH level was measured by enzyme-linked immunosorbent assay (ELISA). The expression of phosphor-CREB, PKCsigma, PKCtheta and phosphor-PKCsigma was determined by Western blotting. The results showed that GHRP-6 stimulated GH secretion in both time- and dose-dependent manners and enhanced the effect of GHRH on GH secretion. GHRP-6 was also found to induce CREB phosphorylation. Moreover, GH secretion was enhanced by the PKC activator PMA and reduced by the PKC inhibitors (Gö6983, rottlerin) and knockdown of PKCsigma. PKCsigma could be activated by GHRP-6. It is concluded that PKC, especially PKCsigma, mediates CREB phosphorylation and GHRP-6-induced GH secretion.

OBJECTIVETo introduce the clinical application of venous nutrition flap pedicled by medial plantar artery of the hallux on the medical aspect of the foot.

METHODSBased on the anastomoses between the medial plantar artery of the hallux and the nutritional vein, the flap was designed with the perforator of medial plantar artery adjacent to the first metatarsal bone as the rotation point. The flap axis was along the vein at the medial aspect of the foot between rotation point and medial malleolus.

RESULTS5 cases were treated with primary healing and complete survival flaps. The patients were followed up for 1-12 months with good match of texture and color.

CONCLUSIONSThe venous nutrition flap pedicled by medial plantar artery of the hallux on the medical aspect of the foot can be transpositioned to repair the defect at forefoot.

Objective To explore the correlations of adult attachment with interpersonal conflict resolu-tions styles and differences between soldiers and employees. Methods Relationship questionnaire (RQ),experi-ence in close relationships (ECR),and Rahim handling interpersonal conflict inventory (ROCI-II) were adminis-tered to 543 employees from different enterprises in Beijing and Liaoning province and 701 soldiers. Results The results suggested the distribution of adult attachment style between soldiers and employees were significantly differ-ent. Compared with employees, there were higher dismissing hat lower secure rate in soldier sample. On handling interpersonal conflict strategy indices, such as integrating, avoiding, dominating and obliging but not compromising (t_((1120))=1.97, P<0.05), there were no significant differences between soldiers and employees. Only on in-tegrating, there were significant ditterenees among four adult attachment styles (F_((3,1009))=10.18, P<0.001).Attachment avoidance had a significantly negative correlation with integrating, obliging and compromising (r=-0.31,-0.11,-0.13 respectively), while attachment anxiety had moderate but significant correlations with a-voiding, dominating and obliging and compromising (r=0. 16,0.35, 0.35, 0.39, 0.30 respectively). Conclu-sion Adult attachment is closely related to handling interpersonal conflict strategies, and there was difference on compromising between soldiers and employees.

Objective To evaluate the effect of Diver CE aspiration thrombus catheter used in patients during the recovery of acute myocardial infarction (AMI) with percutaneous coronary intervention (PCI). Methods A total of 50 AMI patients were enrolled from January 2010 to December 2011. Twenty-ifve patients received PCI and used the Diver CE aspiration thrombus catheter (aspiration group);and the other 25 patients received routine PCI (routine PCI group). The basic characteristics, PCI characteristics, myocardial perfusion indexes and clinical data were compared and analyzed. Results There was no statistically difference between two groups in basic characteristics. Compared with the routine PCI group, higher rate of myocardial blush grade 3 but lower thrombus scores were found in the aspiration group. The incidence of no-lfow or slow-lfow were also lower in aspiration group (all P<0.05). The LVEF after 6 and 12 months were higher in the aspiration group (both P<0.05), no difference in MACE between the two groups. Conclusions Using the Diver CE thrombus aspiration in PCI is a simple and safe by method for treatment of acute myocardial infarction with high thrombosis burden. It can improve reperfusion decrease the rates of no-relfow on slow-relfow and can improve the long-term left ventricular function.

The study introduced the general evaluation indicator system for community health services in Shanghai and its characteristics,analyzing the results of the comprehensive evaluation from the aspects of regions and institutions.From six aspects of financial input,human resource construction, operation mechanism,family doctor system,information system construction and the application of the comprehensive evaluation results,the paper recommended on deepening the reform of community health services.

Osteoporotic fracture is the most major complication of osteoporosis. It is a significant global public health problem which continues to bring serious family and social burden. In order to improve the prevention and treatment of osteoporotic fractures， many countries have carried out new ways of fracture prevention and management， and achieved some results. Prevention mainly aims at those at high risk of fracture， and includes new health education on fracture and the promotion of fall prevention measures. For management， the "Fracture liaison services" mode is mainly applied to the fracture patients， with refined patient management to deal with the fractures that have occurred. This article summarizes the global prevalence of osteoporotic fractures， risk factors， and the current research progress in fracture prevention and management in China and the West.

Antipyretic-analgesics are currently one of the most prescribed drugs in children.The clinical application of antipyretic-analgesics for children in our country still have irrational phenomenon, which affects the therapeutic effect and even poses hidden dangers to the safety of children.In this paper, suggestions were put forward from the indications, dosage form/route, dosage suitability, pathophysiological characteristics of children with individual differences and drug interactions in the symptomatic treatment of febrile children, so as to provide reference for the general pharmacists when conducting prescription review.
