[Summary] The ossification of the posterior longitudinal ligament ( OPLL ) is caused by environmental , genetic and other factors.With the development of genomics research , researchers have found that mutations are important factors inducing OPLL . Despite the genomics research on OPLL has made important advances , no highly correlation has been found between OPLL and the exact single nucleotide polymorphisms (SNPs) loci.The pathogenesis of OPLL needs further exploration .

AIM:To evaluate the role of inhaling N 6-phenyl-2R-isopropyl-adenosine (R-PIA) on the airway resistance and pulmonary compliance of experimental asthmatic guinea-pigs. METHODS: Experimental model of asthmatic guinea-pigs were made. Inhaling R-PIA 5 mg/mL( 5 mg R-PIA in 1 mL 0.9% saline). The airway resistance, pulmonary compliance and NO- x, cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP),tumor necrosis factor (TNF) in bronchoalveolar lavage fluid (BALF) were observed. RESULTS: Compared with asthma group, after inhaling R-PIA, the airway resistance of experimental asthmatic guinea-pigs increased ( P 0 05). CONCLUSION: Inhaling R-PIA could constrict the airway of experimental asthmatic guinea-pigs.

Objective:To investigate the clinical value of serological test indicators in the identification of primary and metastatic liver cancers. Methods:We detected the serum levels of ALT, AST, ALP, TBIL, DBIL, GGT, CHE, 5'-NT, CA199, CEA, and AFP in primary hepatic carcinoma (PHC;120 cases), metastatic hepatic carcinoma (MHC;135 cases), and no liver metastatic control (135 cas-es) groups. The methods used were variance analysis and Scheffe test. ROC curve analysis was used to determine the diagnostic value of CA199 , CEA, and AFP in PHC and MHC. Results:The difference between the serum levels of AST, ALP, GGT, 5'-NT, AFP, and CEA of the PHC and MHC groups was statistically significant (P<0.05). The AFP, CEA, and CA199 areas under the ROC curve of the PHC and MHC groups revealed that AFP diagnosis of primary liver cancer had certain accuracy, whereas CEA and CA199 have some diagnostic value in differentiating primary and metastatic liver cancers. Conclusion: The detection of serum levels of AST, GGT, 5'-NT, AFP, CA199, and CEA in malignant tumor was a preliminary diagnosis of liver metastasis and can provide evidence for the dif-ferential diagnosis of PHC and MHC.

OBJECTIVETo study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites.
METHODSRecruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed.
RESULTSMore than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (P<0.05).
CONCLUSIONThe differences in the metabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

AIM: To explore regulation of lipopolysaccharide (LPS)-induced elevation of Ca 2+ intracellular level in alveolar macrophages(AMs) from patients with chronic bronchitis by Angelica Sinensis and nifedipine.METHODS:AMs was obtained from 7 patients with chronic bronchitis and 6 normal controls by bronchoalveolar lavage and intracellular Ca 2+ level was detected after adding Angelica Sinensis, nifedipine or LPS to the supernatant of AMs loaded by Fura-2. RESULTS: In contrast with normal control group (99.65?32.21 nmol/L), intracellular Ca 2+ level in AMs from chronic bronchitis group (189.47?23.69 nmol/L) was increased significantly in the absence of extracellular Ca 2+ but not 1 mmol/L. Intracellular Ca 2+ level in AMs from chronic bronchitis group were significantly increased by adding 10 ?g/mL LPS to the supernatant of AMs. LPS-induced elevation of intracellular Ca 2+ level in AMs from chronic bronchitis group was completely inhibited by Angelica Sinensis or nifedipine.CONCLUSION: Both Anelica Sinensis and nifedipine may inhibit activation of AMs from patients with chronic bronchitis by reducing LPS-induced elevation of intracellular Ca 2+ level in AMs, suggested that these two medicines may inhibit non-specific inflammation of airways in chronic bronchitis.

ObjectiveTo determine the effect of telmisartan on the levels of serum adiponectin and C-reactive protein(hs-CRP)in elderly hypertensive patients with unstable angina pectoris. MethodsOne hundred and twenty elderly hypertensive patients with unstable angina pectoris were randomized into two groups, telmisartan(n=60) and perindopril(n=60) groups.The levels of hs-CRP,adiponectin, lipid factors, fasting plasma glucose (FPG), insulin and insulin sensitivity index (ISI) were measured before and 6 months after telmisartan and perindopril treatments.ResultsAt the end of 6 months, the telmisartan group showed more reduction in plasma levels of hs-CRP and more increment in serum adiponectin concentrations and ISI significantly. The frequency of cardiovascular events was significantly lower in the patients of the telmisartan group than that of the perindopril group.ConclusionsCompared with perindopril, telmisartan significantly decreases plasma levels of hs-CRP and increases serum adiponectin concentrations in elderly hypertensive patients with unstable angina pectoris. It also significantly decreases the frequency of cardiovascular events in these patients.

BACKGROUND:Kienb?ck disease lacks of suitable animal models, which are similar to the pathological process of avascular necrosis of human lunate bone.
OBJECTIVE:To establish a new animal model of Kienb?ck disease using medical TH adhesive embolism and to explore the rationality of model establishment.
METHODS:A total of 30 healthy adult New Zealand rabbits, male or female, were selected. Using self-control method, the rabbits were randomly assigned to experimental sides and control sides. By dril ing in the center of the lunate bone, 0.2 mL of medical TH glue was injected three times. An equal volume of physiological saline was injected into the center of the lunate bone on the control side. X-ray examination, general observation, Micro-CT measurement of bone, and tissue pathology detection were conducted at 4, 8 and 12 weeks.
RESULTS AND CONCLUSION:Gross specimen, X-ray and histological results showed that ischemic necrosis of the lunate bone on the experimental side was visible at 8 weeks after model induction. The ischemic necrosis of the lunate bone became more typical at 12 weeks. Among the Micro-CT microscopic parameters of trabecular bone, trabecular bone density parameters bone volume fraction and the number of trabecular bone were significantly lower on the experimental side than those on the control side (P<0.05). Spatial parameters of trabecular bone significantly increased. Trabecular separation and structure model index on the experimental side were significantly greater than those on the control side. Results suggested that ischemic necrosis of the lunate bone appeared on the experimental side at 8 weeks after injection of medical TH glue. Rabbit models of ischemic necrosis of the lunate bone can be established at 12 weeks. Thus, alterations, which were similar to ischemic necrosis of human lunate bone, appeared, such as blood transportation damage in the lunate bone, trabecular bone fracture, and empty lacuna, when surrounding tissues were not obviously injured.
