[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 .

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.

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.

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.

ObjectiveTo study the correlation of urinary iodine and thyroid function in elderly men in Harbin,and to provide the basis for formulation of health measures for the elderly.MethodsSeventy five cases of clinically healthy elderly men were enrolled for check-up of urinary iodine,thyroid function and B-ultrasound in Geriatric Ward the Forth Affiliated Hospital of Harbin Medical University in 2010.The subjects of investigation were divided into iodine appropriate and iodine sufficient groups and thyroid function parameters and B-ultrasound results were compared.ResultsThe average age of the 75 cases of healthy elderly men was (79.07 ± 4.78) years old and the median of urinary iodine was 198.4 μg/L.There were 62.67％ (47/75) elderly males whose iodine nutritional status was appropriate,but there were still some individuals(6.67％,5/75) in the iodine excess state.The level of TSH of the iodine appropriate group [(1.91 ± 0.82)mU/L] was lower than that iodine sufficient group [(4.98 ±0.60)mU/L,t =12.58,P ＜ 0.05],while the level of FT3 of the iodine appropriate group[(4.71 ± 0.56)pmol/L]was higher than that iodine sufficient group[(3.31 ± 0.43)pmol/L,t =12.18,P ＜ 0.05].But the difference of FT4between the two groups [(14.91 ± 3.12),(14.06 ± 2.79)pmol/L] was not statistically significant (t =1.40,P ＞0.05].The thyroid volume of iodine sufficient group[(20.9 ± 6.1 )cm3] was higher than that iodine appropriate group [(17.9 ± 5.6)cm3,t =2.11,P ＜ 0.05].ConclusionsSufficient quantities of iodine intake may affect the thyroid of elderly people.Whether the quantity of iodine intake of the elderly population should be decreased or not need to be further studied.

In this study, we designed and synthesized 12 novel aloperine derivatives with different core structures. Among them, compound 3 with a ten-membered ring core was obtained through a special ring expansion reaction after γ-H Huffman elimination of quaternary ammonium salt, and the structure was verified by X-single crystal diffraction. Furthermore, their antiviral activity against human β-coronavirus HCoV-OC43 was evaluated by CCK-8 assay. Quaternary ammonium salt 2a and 3 had a good inhibitory effect against HCoV-OC43, and 2a had the highest anti-HCoV-OC43 activity with an EC₅₀ values of 3.77 μmol·L^-1 and a SI value of over 53.1. Schrӧdinger molecular docking results showed that both 2a and 3 might display their anti-HCoV-OC43 activity by directly acting on host TMPRSS2 and SR-B1. The results expanded the structural types of endocyclic aloperine and the function against coronavirus, and provided useful scientific data for the development of pharmaceutical applications of these compounds.
