1.Osteoporotic chronic pain:how to understand and prevent it?
Chinese Journal of Tissue Engineering Research 2014;(38):6194-6199
BACKGROUND:For the treatment of osteoporosis, clinicians general y focus on improving bone mineral density and reducing the incidence of fractures, but often ignore the ease of osteoporotic chronic pain.
OBJECTIVE:To review the research progress in osteoporotic chronic pain from domestic and overseas literature in recent years in order to provide reference for basic and clinical research.
METHODDatabases of PubMed and Wanfang database were retrieved with key words of“osteoporosis;chronic pain;treatment of osteoporotic;vertebral compression fracture”in English and Chinese to search papers published from March 1999 to March 2014. Articles related to characteristics, pathogenesis and drug treatment of osteoporotic chronic pain as wel as surgical treatment of osteoporotic vertebral compression fractures. Final y 49 articles were summarized according to inclusion criteria.
RESULTS AND CONCLUSION:The pathogenesis of osteoporotic chronic pain includes congestion mechanism and mechanisms of cytokines and lactic acid accumulation, but its exact cytological and biochemical mechanisms are not very clear. Commonly used drugs in the treatment of osteoporotic chronic pain include calcitonin and bisphosphonates. Calcitonin plays an analgesic effect by inhibiting bone resorption to indirectly reduce the hydrogen ion concentration, suppress prostaglandin synthesis, improve animal pain threshold, and increase the plasma concentration of beta-endorphin. The main pharmacological action of bisphosphonate is to inhibit osteoclast formation and activity, inhibit bone absorption, improve osteoporotic bone pain, improve bone mineral density, increase bone strength, and prevent osteoporotic fracture. Benign and malignancy tumor of the spine and osteoporotic spinal compression fractures can be treated with percutaneous vertebroplasty or percutaneous kyphoplasty. After treatment, the vertebral height can be restored completely or partial y, the kyphosis is corrected, the vertebral stability is increased and pain is relieved. Combination of various treatments is effective for the treatment of osteoporotic chronic pain, and meanwhile, the prevention and treatment of osteoporotic fractures has a positive role in prevention and treatment of osteoporotic chronic pain.

Objective To investigate the inhibitory effect of cyclooxygenase-2 (COX-2) inhibitor celecoxib alone and in combination with somatostatin (SST) analog octreotide on human gastric cancer. Methods Fifty one gastric cancer patients were randomly divided into 3 groups. The patients in control group(n=15)took no medicine before gastric cancer resection. Celecoxib group(n=18)patients took celecoxib orally 0.2 g/d for 7 days before surgery. Combination group(n=18) patients took celecoxib orally 0.2 g/d and were injected octreotide 100 ?g/d subcutaneously for 7 days before surgery. The resected specimens were examined histologically, including status of tumor necrosis, inflammatory cells infiltration and fibrous tissue proliferation. The microvessel density (MVD) and the expression of COX-2 in gastric cancer were evaluated by immunohistochemical methods. The apoptosis of tumor cells was measured by terminal deoxynucleotidyl transferse-mediated-dUTP nick end labeling. The expression of somatostatin receptor (SSTR) -1,SSTR-2 and SSTR-3 mRNA in gastric cancer tissue obtained by biopsy in all patients were detected by using real time fluorescence quantitative RT-PCR. Results Compared with control group, gastric cancer tissue necrosis increased significantly(P

This review focuses on the fetal origins of adult disease hypothesis put forward by David Barker and his colleagues,recent advances in epidemiological studies and experimental research in this field.Barker Hypothesis states that environmental factors,particularly intrauterine nutrition,as indicated by birth weight,operate in early life to program the risks for adverse health outcomes in adult life.A large growing body of reports described the association between the early development and adult diseases,such as diabetes,hypertension,coronary heart disease,abnormal lipids metabolism,obesity and cancer,etc.Experimental studies show that the changes of some key genes' expression,caused by epigenetic modifications,lead to a permanent alteration of cellular proliferation and differentiation and finally the genesis in key tissues and organs.These results bring about the impairment in structures and functions and the increased susceptibility to chronic diseases in adult life.The hypothesis provides a new perspective for the prevention and therapy of chronic diseases.

Objective To explore the instructive value of preoperative splenic artery CTA examination on Laparoscopic splenectomy (LS). Methods From January 2008 to February 2010,36 cases requiring Laparoscopic splenectomy (LS) were selected randomly and divided into two groups: CTA group and non-CTA group, 18 cases in each group. As for the CTA group,splenic artery CTA examination was performed before operation,to understand splenic artery and its branches anatomy type and track and then individualized surgical treatment was developed. As for the non-CTA group,a routine surgical procedure was performed. The indices before and during the operation were recorded and compared through χ2 test The operating time and the amount of bleeding in the two groups were compared using t-test Results There were no significant difference between the indices recorded by splenic artery CTA examination and those by laparoscopic splenectomy intraoperation ( P > 0. 05 ) . The operating time was (124. 32 ±21.43) mins in the CTA group, which was significantly shorter than that in the non-CTA group ((148.27 ±28. 36)mins) (P <0. 05). The amount of blood in the CTA group was significantly less than that in the non-CTA group( ( 80. 50 ± 16. 42) ml vs. (101. 35 ± 26.25 ) ml). Conclusions Splenic artery CTA can identify splenic artery and its branches anatomy type and track before LS,therefore guide the development of individualized surgical treatment It increases the safety of LS, reduces bleeding and shortens the operational time. It has an instrutive value to laparoscopic splenectomy.
