ObjectiveTo study the relationship between osteoporosis and carotid artery disease in the elderly. Methods102 elderly patients were registered for this study and the extraeranial carotid was detected by ultrasound scan. The carotid intima-media thickness (IMT) and the plaque index (PI) were measured and calculated respectively. Meanwhile the patients were divided into two groups according to the results of bone mineral density (BMI) measurement: the osteoporosis group and the non-osteoporosis group. The IMT, PI, carotid stenotic rate and some biochemical parameters were recorded and compared between the two groups. Relationship between these parameters and osteoporosis were evaluated by logistic regression model and partial correlation analysis. ResultsThe differences in serum calcium and the levels of TC,TG,HDL and LDL between osteoporosis group and non-osteoporosis group were statistically significant (all P＜0.05), while the level differences in serum phosphorus, fasting blood glucose and uric acid had no statistical significance between the two groups (P＞0.05). Moreover, the IMT and PI in osteoporosis group were significantly higher than those in non-osteoporosis group (P＜0.05). Among the 102 patients, 48 cases showed the carotid stenotic rate ＞ 50%, including 41 patients in osteoporosis group as well as 7 patients in non-osteoporosis group(P＜0.05). Logistic regression showed that age, HDL-C, IMT, PI and carotid stenotic rate＞50 % were the correlated factors of osteoporosis and among them, IMT, PI and carotid stenotic rate＞50% had higher risks (OR = 17.13,99.33,289.13). There was positive correlation between the carotid artery disease and osteoporosis. ConclusionsThere is a relationship between osteoporosis and carotid artery disease in the elderly. Emphasis should be paid on comprehensive prevention for osteoporosis and carotid artery disease in the elderly.

Objective:To investigate and evaluate the effect of antibacterial agents clinical use and management training for medi-cal institutions in Hubei province in order to promote rational antibacterial drug use. Methods:A questionnaire was designed, inclu-ding basic conception, medication principle, mechanism and medication feature etc. The data were studied by SPSS 13. 0 software to analyze the knowledge level of antibacterial agents in medical staffs. Results: Medical staffs had good acquisition in the knowledge points involved in choice questions. The correct percentage of each scoring in essay questions differed considerably within the range of 7. 88%-99. 01%. Management rules could be well understood, while the definition of antibacterial drugs and the difference between antibacterial drugs and antibiotics were paid little attention. Conclusion: The overall knowledge level of rational antibacterial agents use in the trainees is promising with comprehensive understand of the management rules. It's necessary to distinguish antibacterial a-gents from antibiotics more clearly.

OBJECTIVE: To evaluate the application of MSCT and post-processing images to fractures of nasal bone in forensic identification. METHODS: 134 cases were examined by thin slice scanning with MSCT and all of the data were sent to workstation for MPR and SSD. The result of MSCT was compared with that of X-ray. RESULTS: There are 55 (41.04%) cases of linear fracture, 46 (34.33%) cases of comminuted fracture, 27 (20.15%) cases of depressed fracture and 6 (4.48%) cases of no fracture in this sample. With X-ray or CR, 48 (35.82%) cases were misdiagnosed or underdiagnosed. 133 (99.25%) cases were confirmed by MSCT. Significance difference was found between X-ray and MSCT (chi2= 45.0816, P<0.001). CONCLUSION MSCT and post-processing images might be the chief evidence for nasal fractures in forensic identification.

OBJECTIVETo observe the effect of Pinggan Qianyang Recipe (PQR) on inhibiting angiotensin II (Ang II) induced proliferation and migration of vascular smooth muscle cells (VSMCs) and changes of DNA methylation.

METHODSVSMCs were cultured using tissue explant method, and PQR containing serum was prepared. Primarily cultured VSMCs were divided into four groups, the normal group, the model group, the folate group (folic acid intervention) , and the PQR group. The proliferation and migration of VSMCs was duplicated by Ang II. After 24-h Ang II induced culture, 40 microg/mL folic acid was added to the folate group for 48 h, while 5% PQR containing serum was added to the PQR group for 48 h. The cell growth curve of VSMCs was drawn by using Cell Counting Kit (CCK-8). The proliferative activity of VSMC was determined by MTT assay. The migration of VSMCs was measured by Millicell chamber. The general level of cytosine methylation in cell nucleus was detected via 5-mC antibodies immunofluorescence, and mRNA expression levels of DNA methyltransferase 1 (DNMT1) were measured by Real-time q-polymerase chain reaction (q-PCR).

RESULTSVSMCs were promoted by Ang II at 10(-6) mol/L for 24 h. Compared with the normal group, the proliferative activity and migration quantity of VSMCs obviously increased, and DNA methylation level obviously decreased (P < 0.05, P < 0.01). Compared with the model group, the cell growth, proliferative activity and migration quantity of VSMCs obviously decreased and the general DNA methylation level increased in the folate group and the PQR group (P < 0.05, P < 0.01). Compared with the normal group, the mRNA expression of DNMT1 decreased in the model group (P < 0.01). Compared with the model group, mRNA expression of DNMT1 in Ang II induced VSMCs was obviously enhanced in the folate group and the PQR group (P < 0.01).

CONCLUSIONSPQR could inhibit Ang II induced proliferation and migration of VSMCs, and cause high genomic DNA methylation level. Changes of DNA methylation might be associated with DNMT1 expression.

OBJECTIVETo investigate the expression of the augmenter of liver regeneration (ALR) in cryptorchidism spermatogenic cells.

METHODSTwenty cryptorchidism rat models were established by surgery, 10 included as normal controls and anther 10 as sham-surgery controls. The expression of ALR was detected by immunochemistry, the COX II level measured by immunofluorescence and the ferric iron contents assayed by Perls stain.

RESULTSALR expressed intensively in the spermatogonia of the control groups but in a signigicantly diminished manner in the cryptorchidism group. No significant difference was found in the COX II level between any two groups of the same age. Ferric iron content of the PND30 cryptorchids decreased significantly (P < 0.05).

CONCLUSIONALR may play an important role in early spermatogenesis. Metabolism dysfunctions caused by ALR defection might be a crucial mechanism for aspermatogenesis of cryptorchidism.

OBJECTIVETo study the correlation between hepatitis B virus surface antigen (HBsAg) and hepatitis C virus (HCV) expression as well as fibrosis staging in hepatocellular carcinoma (HCC) and pericarcinomatous tissues.

METHODSThe patterns of HBsAg and HCV in 100 cases of HCC and their surrounding liver tissues were studied on paraffin-embeded sections with immunohistochemistry technique, and liver tissues were also staged.

RESULTSHBV, HCV virus infection were positively correlated with the fibrotic staging (r(s) = 0.32, P = 0.001). HBsAg and HCV were detected both in HCC and pericarcinomatous tissues. The positive rate of HBsAg in Pericarcinomatous Tissues (79%) was higher than that of in HCC tissues (23%). HCV expressions in HCC (15%) and pericarcinomatous tissues (23%) showed no significant differences.

CONCLUSIONThe fibrotic degree in the tissues of liver cancer with previous virus infection was obviously higher than that without virus infection. Viral infection seemed to be one of the reasons causing liver cancer while perennial virusemia would aggravate pathological changes of the liver tissue.

Objective To investigate the effect of acupuncture plus rehabilitation training on upper limb functional recovery in convalescent stroke patients.Methods One hundred and three convalescent stroke patients with upper limb motor dysfunction were randomized to a treatment group (54 cases) and a control groups (49 cases). Both group received conventional rehabilitation training. In addition, the treatment group received along-meridian syndrome differentiation-based acupuncture and the control group, sham acupuncture. Upper limb Fugl-Meyer Assessment (U-FMA) score, the Wolf Motor Function Test (WMFT) score, the modified Barthel Index (MBI) score and the 36-Item Short Form Health Survey (SF-36) score were recorded in the two groups of patients before and at the end of treatment and at the 3-month follow-up.Results In the two groups there were statistically significant differences in the U-FMA score, the WMFT score and the MBI score at the end of treatment and the 3-month follow-up compared with before (P>0.05 orP<0.01). At the end of treatment and the 3-month follow-up there were statistically significant differences in the U-FMA score, the WMFT score and the MBI score between the treatment and control groups (P<0.05 orP<0.01). The scores of SF-36 items except social functioning and bodily pain had statistically significant differences within the two groups at the end of treatment and the 3-month follow-up compared with before and between the two groups at the end of treatment and the 3-month follow-up (P<0.01 orP<0.05).Conclusion Acupuncture plus rehabilitation training can markedly improve upper limb function in stroke patients.

OBJECTIVETo explore the character of inorganic elements in Asari Radix et Rhizoma (Xixin).

METHODThe contents of 53 inorganic elements in Xixin samples from different localities and species were determined by ICP-AES and ICP-MS. The statistical data were made using SAS.

RESULTThe result demonstrated that Xixin has the high contents of Fe, Cr, Li. It has been observed that the content of Cu and Pb of the samples are much higher than the standard level. The results of hierarchical cluster analysis revealed two groups which correspond with the species of the samples. No correlations between the contents of the inorganic elements and the localities of the samples were found. Some characteristic elements were displayed in some specific areas. The difference of the contents of the 53 inorganic elements between root and rhizome of Xixin was reported for the first time. The primary form of inorganic elements in Xixin has been studied for the first time. The result demonstrated that the extraction rate between different elements varied, with the average extraction rate of (22.25 +/- 24.96)%.

CONCLUSIONThe inorganic elements analysis of Xixin can provide evidence of its identification, cultivation and application.

OBJECTIVETo study the correlation between HBsAg and HCV in hepatocellular carcinoma (HCC) pericarcinomatous tissues and serum liver fibrosis markers.

METHODSThe patterns of HBsAg and HCV in 100 cases of HCC and their surrounding liver tissues were studied with paraffin sections using immunohistochemistry techniques. Hyaluronic acid (HA), procollagen III peptide (PIIIP), collagen IV (CIV), and laminin (LN) were detected by radioimmunoassay.

RESULTSThe levels of HA, PIIIP, CIV and LN in the HBV and HCV coinfection group were the highest among the four groups. The levels of HA, PIIIP, CIV and LN in the groups not infected by HBV and HCV were the lowest among the four groups. HBV and HCV expressions were positively correlated with HA, LN and CIV and their Spearman's rank correlation coefficients were 0.60, 0.45, 0.46, respectively (P < 0.01).

CONCLUSIONLiver cancer development follows a sequential trend of chronic hepatitis, liver cirrhosis, and liver cancer. In the tissues of liver cancer with virus infection background, the serum marker level of hepatic fibrosis is obviously higher than those without virus infection background. On the one hand, virus infection is one of the reasons causing liver cancer; and on the other hand, longstanding viremia will aggravate pathological changes of liver tissues. Therefore antivirus treatment of hepatitis is of significance for the prognosis of liver cancer.
