LPA kringle IV type 2 is associated with type 2 diabetes in a Chinese population with very high cardiovascular risk.

The connection between lipoprotein (a) [Lp(a)] levels and the risks of cardiovascular disease and diabetes remains poorly understood. Lp(a) is encoded by the LPA gene, and evidence suggests that the kringle IV type 2 (KIV-2) variant is particularly important to Lp(a) isoform size. A large isoform size, represented as a high number of KIV-2 repeats in LPA, is associated with low serum Lp(a) concentrations and an increased risk of type 2 diabetes. We investigated the associations among Lp(a) concentrations, LPA KIV-2 repeats, and type 2 diabetes in a Chinese population of 1,863 consecutive patients with very high cardiovascular risk, as identified by coronary angiography. Individuals with Lp(a) levels in the top tertile [67.86 (35.34-318.50) mg/dl] had a lower risk of diabetes compared with those in the bottom tertile [7.38 (0.60-12.91) mg/dl]. There was an inverse association between the number of KIV-2 repeats and serum Lp(a) concentrations. This study demonstrated that a high number of LPA KIV-2 repeats are associated with increased risk of type 2 diabetes in a Chinese population with very high cardiovascular risk, which suggests that large Lp(a) isoform size, associated with low Lp(a) concentration, has a causal effect on type 2 diabetes.

[Analysis of X-rays of cervical imbalances syndrome before and after the treatment of osteopathy and traction intervention in 187 youth cases].

OBJECTIVE: To observe X-ray features of before and after treatment of cervical imbalance syndrome with osteopathy and traction intervention in youth patients, then to investigate the clinical effect of the treatment of the cervical imbalances syndrome in youth by osteopathy. METHODS: From September 2007 to December 2010, one hundred and eighty-seven students of 19 to 22 years (means 21 years) with neck pain as the main symptom in Beijing university of Chinese medicine were selected and divide them into osteopathy group and traction groups randomly. In osteopathy group, there were 94 patients including 40 males and 54 females; in traction group, there were 93 patients including 42 males and 51 females. The treatment of osteopathy group lasted for 3 weeks,three times per week; traction group by traction treatment three weeks,three times a week, too. X-ray before treatment and 3 weeks after treatment were collected. RESULTS: The osteopathy group:94 cases, before treatment, abnormal curvature in 57 cases, spinous position change in 45 cases and angular displacement in 44 cases, vertebral sliding in 15 cases, Ruth Jackson line intersect proneness change in 70 cases,stretch change in 47 cases; after treatment, abnormal curvature in 35 cases, spinous position change in 24 cases and angular displacement in 18 cases, vertebral sliding in 3 cases, Ruth Jackson line intersect proneness change in 41 cases, extension change in 33 cases; X-Ray measurement results: cervical curvature improved from (7.070 +/- 4.629) degrees before treatment to (7.660 +/- 4.156) degrees after treatment, angular displacement improved from (13.790 +/- 2.590) degrees before treatment to (11.050 +/- 2.560) degrees after treatment; vertebral sliding improved from (3.770 +/- 0.350) mm before treatment to (3.160 +/- 0.485) mm after treatment. The change of angular displacement and vertebral sliding were so significant before and after treatment in this group, there were statistical defferences between before and after the treatment (P < 0.01) in osteopathy group. The traction group: 93 cases, before treatment,abnormal curvature in 60 cases, spinous position change in 39 cases and angular displacement in 39 cases, vertebral sliding in 15 cases, Ruth Jackson line intersect proneness change in 70 cases, stretch in 47 cases; after treatment,abnormal curvature in 50 cases, spinous position change in 29 cases and angular displacement in 17 cases; vertebral sliding in 3 cases, Ruth Jackson line intersect proneness change in 41 cases, stretch in 33 cases; X-Ray measurement results: cervical curvature improved from (5.590 +/- 4.639) degrees before treatment to (5.990 +/- 4.330) degrees after treatment, angular displacement improved from (13.360 +/- 2.064) degrees before treatment to (11.210 +/- 1.872) degrees after treatment; vertebral sliding improved from (3.790 +/- 0.339) mm before treatment to (3.480 +/- 0.332) mm after treatment. The change of angular displacement and vertebral sliding were also so significant in traction group before and after treatment, there were statistical defferences between before and after the treatment (P < 0.01). CONCLUSION: (1) Pathological changes can be called youth cervical imbalance syndrome. (2) Stress points, angular displacement, cervical vertebral slip, curvature straightened, spinous position change are main X-ray performances. (3) Both osteopathy and traction intervention on are efficient in youth neck pain. (4) Youths cervical vertebra imbalance is early but reversible performance.

[Multiple linear regression analysis of X-ray measurement and WOMAC scores of knee osteoarthritis].

OBJECTIVE: To perform Multiple Linear Regression analysis of X-ray measurement and WOMAC scores of knee osteoarthritis, and to analyze their relationship with clinical and biomechanical concepts. METHODS: From March 2011 to July 2011, 140 patients (250 knees) were reviewed, including 132 knees in the left and 118 knees in the right; ranging in age from 40 to 71 years, with an average of 54.68 years. The MB-RULER measurement software was applied to measure femoral angle, tibial angle, femorotibial angle, joint gap angle from antero-posterir and lateral position of X-rays. The WOMAC scores were also collected. Then multiple regression equations was applied for the linear regression analysis of correlation between the X-ray measurement and WOMAC scores. RESULTS: There was statistical significance in the regression equation of AP X-rays value and WOMAC scores (P<0.05), while there was no statistical significance in the regression equation of lateral X-ray value and WOMAC scores (P>0.05). CONCLUSION: 1) X-ray measurement of knee joint can reflect the WOMAC scores to a certain extent. 2) It is necessary to measure the X-ray mechanical axis of knee, which is important for diagnosis and treatment of osteoarthritis. 3) The correlation between tibial angle,joint gap angle on antero-posterior X-ray and WOMAC scores is significant, which can be used to assess the functional recovery of patients before and after treatment.

[Two patterns of mediastinal lymph node resection for non-small cell lung cancer of stage IIIA: survival analysis of 219 cases].

BACKGROUND & OBJECTIVE: Correctly dealing with mediastinum lymph nodes during operation is critical to the prognosis of resectable non-small cell lung cancer (NSCLC) of stage IIIA, but the removal extent of mediastinum lymph nodes is controversial. This study was to explore the effects of 2 patterns of mediastinum lymph node resection on long-term survival of stage IIIA NSCLC patients. METHODS: Clinical data of 219 stage IIIA NSCLC patients, underwent complete resection from Jan. 1999 to Jan. 2004 in Xinjiang Tumor Hospital, were reviewed. Of the 219 patients, 109 underwent mediastinal lymph node sampling (LS), and 110 underwent systematic mediastinal lymphadenectomy (SML). Survival statuses of the patients were analyzed by Life table method and Kaplan-Meier method; the prognosis was analyzed with Cox multivariate regression model. RESULTS: The 1-, 3-, and 5-year survival rates were 82%, 28%, 13% in LS group, and 88%, 37%, 16% in SML group. The median survival time was significantly longer in SML group than in LS group (23.5 months vs. 20.0 months, P<0.05). Cox multivariate analysis showed that histopathologic type, metastasis state of mediastinal lymph nodes, mediastinum lymph node resection pattern were prognostic factors of stage IIIA NSCLC patients. CONCLUSION: As compared with LS, SML in radical operation could improve the survival rate of stage IIIA NSCLC patients.
