Objective: To study influence of glycosylated hemoglobin A1c (HbA1c) on major adverse cardiovascular events (MACE) in patients with diabetes mellitus (DM) complicated coronary heart disease (CHD) after percutaneous coronary intervention (PCI).Methods: A total of 100 DM+CHD patients after PCI were selected from our hospital.According to HbA1c level, they were divided into HbA1c<6.5% group (n=48) and HbA1c≥6.5% group (n=52).Levels of C reactive protein (CRP), tumor necrosis factor α (TNF-α), erythrocyte sedimentation rate (ESR) and interleukin (IL)-6 before PCI, incidence rate of MACE on six and 24 months after PCI were compared between two groups.Results: Compared with HbA1c<6.5% group before PCI, there were significant rise in serum levels of CRP[(18.5±6.2) mg/L vs.(25.8±4.2) mg/L]and TNF-α[(32.4±12.3) ng/L vs.(48.3±11.8) ng/L]in HbA1c≥6.5% group, P<0.01 both.On six months after PCI, incidence rate of myocardial infarction in HbA1c≥6.5% group was significantly higher than that of HbA1c<6.5% group (9.62% vs.0, P=0.028);24 months after PCI, compared with HbA1c<6.5% group, there were significant rise in incidence rates of myocardial infarction (2.08% vs.15.38%) and diseased vessel restenosis (12.50% vs.32.69%) in HbA1c≥6.5% group (P<0.05 all).Conclusion: In DM+CHD patients after PCI, those with lower HbA1c level possess better prognosis.

Objective To investigate the changes of compliance in large arteries and carotid artery intima-media thickness(IMT)in patients with metabolic syndrome.Methods There were 64 patients with metabolic syndrome and 56 age-matched control subjects.Their carotid-femoral pulse wave velocities(C-FPWV)were measured by the Complior SP and their carotid artery IMT were detected by B-mode ultrasound.At the same time their height,weight,waist circumstance,hip girth,blood pressure,blood glucose,blood lipid,BMI and waist to hip ratio(WHR)were measured.Results Compared with the control,the patients with metabolic syndrome had higher C-FPWV(P

BACKGROUND:MRI characterized as non-invasion, high resolution, high sensitivity and specificity to injury has become another important means for diagnosis of knee joint disease folowing the arthroscopy. OBJECTIVE: To explore the effective evaluation on the knee meniscus injury diagnosis, by comparing the results of MRI and arthroscopy of the knee meniscus. METHODS: Clinical data of 206 patients with meniscus injury were retrospectively analyzed. Every case was subjected to MRI and the arthroscopy. The findings of arthroscopy were considered as the golden standard. Then, the sensitivity, specificity and coincidence rate of MRI in the diagnosis of meniscus injury were calculated. The chi-square analysis was used to evaluate the MRI and arthroscopy in the diagnosis of meniscus injury. The Kappa values were used to test the consistency of MRI with arthroscopy in the diagnosis of meniscus injury. RESULTS AND CONCLUSION:For levels 0 and I meniscus injury, the coincidence rate of MRI was 97%; for level II meniscus injury, the coincidence rate of MRI was 91.1%, and there was no significant difference (P > 0.05). For level III meniscus injury, the sensitivity, specificity, concordance rate and Youden index of MRI were 92.9%, 94.4%, 93.7% and 87.3%, respectively. By the consistency checking, the value of Kappa was 0.874 and χ2 so there was a high consistency checking between the data of MRI and arthroscopy (P=0.000). MRI is a noninvasive diagnostic method for meniscus injury. For patients with levels I and II meniscus injury on MRI, arthroscopy should be cautiously adopted; however, for patients with level III meniscus injury on MRI, arthroscopy should be done as early as possible. Arthroscopic observation is more intuitive that enables to make accurate judgments of meniscus injury to reduce the rate of misdiagnosis.

Objective To compare the pathological and serological difference of rheumatoid arthritis (RA) models in severe combined immunodeficiency (SCID) mice transplanted with synovial tissues from patients with rheumatoid arthritis (SCID-HuRAg mice) established either by renal capsule or subcutaneous back heterotopic transplantation. Methods RA synovium and normal human cartilage were co-implanted subcutaneously into the backs or under the renal capsule of 15 SCID mice. Engrafted tissues and serum were taken at the 4th and 8th week after transplantation. Histopathology and ELISA were performed to compare their histological and serological differences with RA. Results The morbidity and taken rate were significantly increased in the subcutaneous back of the mice group than the renal capsule group. The degree of cartilage erosion as well as the titers of serum IgM type rheumatoid factor suggested no significant difference between the two groups of SCID-HuRAg model devel oped by different engraft methods. Conclusion Back subcutaneous transplantation SCID-HuRAg model can be an ideal and stable animal model for studies on the pathogenesis and biotherapy of RA.

Objective: To explore therapeutic effect of recombinant human brain natriuretic peptide (rhBNP) in aged patients with acute decompensated heart failure (ADHF).Methods: A total of 98 aged ADHF patients treated in our hospital were selected and randomly divided into routine treatment group (n=50) and rhBNP group (n=48, received intravenous injection of rhBNP based on routine treatment group).After 72h treatment, cardiac function indexes, total effective rate and incidence of adverse drug reactions (ADR) were measured and compared between two groups.Results: Compared with before treatment, after 72h treatment, there were significant rise in left ventricular ejection fraction (LVEF) and 24h urine volume in both groups(P=0.001 all);compared with routine treatment group after treatment, there were significant rise in LVEF [(45.9±7.8)% vs.(57.4±7.9)%] and 24h urine volume [(1637.5±103.2)ml vs.(1836.4±118.4)ml], P=0.001 all.On 7d after treatment, total effective rate of rhBNP group was significantly higher than that of routine treatment group (93.75% vs.82.00%, P=0.033).There was no significant difference in incidence rate of ADR between two groups, P=0.898.Conclusion: Recombinant human brain natriuretic peptide can significantly improve heart function, and the therapeutic effect is significant in aged patients with acute decompensated heart failure.

This study examined the effect of ischemia-reperfusion injury on the expression of Pim-3 gene in myocardial tissues and their underlying mechanism. Rat models of myocardial ischemia-reperfusion injury were established by ligating the left anterior descending coronary artery of the rats. A total of 30 SD male adult rats were randomly divided into 5 groups: group A (sham operation, n=6); group B (in which the rats were subjected to 15 min of ischemia by ligation of the left anterior descending coronary artery, n=6); group C (in which the rats received 30 min of ischemia, n=6), group D and group E (in which the left anterior descending coronary artery of the rats were ligated for 30 min and then reperfused for 30 min or 120 min, n=6 in each). The left ventricular tissues were removed immediately after the ischemia-reperfusion injury. Neonatal cardiomyocytes were cultured and treated with different concentrations of H(2)O(2) (0, 5, 10, 20 μmol/L) or tumor necrosis factor-α (TNF-α, 0, 1, 5, 10 ng/mL). The mRNA and protein expression of Pim-3 gene was determined by using RT-PCR, western blotting and immunohistochemistry. Additionally, neonatal cardiomyocytes were transfected with Pim-3 siRNA, and induced to develop apoptosis by using H(2)O(2). The results showed that normal myocardial tissues expressed a quantity of Pim-3 gene mRNA and protein. Ischemia-reperfusion injury could up-regulate the mRNA and protein expression of Pim-3 gene in myocardial tissues. Furthermore, H(2)O(2) but not TNF-α up-regulated the Pim-3 gene expression in cultured cardiomyocytes. And Pim-3 silencing failed to strengthen the H(2)O(2)-inducing apoptosis in cardiomyocytes. It was concluded that ischemia-reperfusion injury up-regulated the Pim-3 gene expression through oxidative stress signaling pathway in myocardial tissues.

Pim kinases contribute to tumor formation and development of lymphoma, which shows enhanced DNA replication, DNA recombination and repair. Endothelial cells^(ECs) express all the three members of Pim kinase gene family. We hypothesized that DNA repair gene would regulate Pim expression in ECs. Human umbilical vein endothelial cells (HUVECs) were isolated and maintained in M199 culture medium. The cellular distribution of Pim-3 in ECs was determined by immunofluorescent staining. The siRNA fragments were synthesized and transfected by using Lipofectamine LTX. The total cellular RNA was extracted from the cells by using Trizol reagent. cDNAs were quantified by semi-quantity PCR. The effects of LY294002 and wortmannin on RNA stability in ECs were also examined. Our data showed that LY294002 and wortmannin, phosphatidylinositol 3-kinase (PI3K) and PI3K-like kinase inhibitors, increased Pim mRNA expression in ECs without altering the mRNA stability. RNA interference (RNAi) targeting DNA-dependent protein kinase catalytic subunit (DNA-PKcs) and ataxia telangiectasia mutated (ATM) increased mRNA expression of Pim-3 and Pim-1, respectively. Silencing of Akt decreased Pim-1 instead of Pm-2 and Pim-3 gene expression in ECs. But etoposide, a nucleoside analogue, which could activate DNA-PKcs and ATM, increased Pim expression in ECs. Our study indicates that the expression of Pim kinases is physiologically related to DNA-PKcs and ATM in ECs.

OBJECTIVE: To investigate the efficacy of the treatment of endoscopic sinus surgery on patients dignosed as chronic sinusitis with nasal polyps(CRSwNP) complicated and asthma. METHOD: Data of 45 patients with CRSwNP complicated asthma were analyzed retrospectively. RESULT: All cases were followed up for a period of 1 to 3 years after operation. In the 45 cases treated with ESS, 32 cases were cured, 9 cases were improved and 4 cases were inefficient by the treatment. The cure rate was 91.1% (41/45). The asthma symptoms were improved in 16 patients compared to 4 before the surgery. CONCLUSION With ESS based on combined therapy,it can significantly improve the condition of CRSwNP, asthma symptoms and pulmonary function. Meanwhile, sufficient perioperative period preparation should be made to ensure the safety of the operation.

OBJECTIVE: To investigate the clinopathological characteristics, differential diagnosis, therapy and prognosis of sinonasal mucosal malignant melanoma. METHOD: Clinopathological data of 18 cases which were diagnosed by pathology and immmunohistochemistry were analyzed retrospectively. All cases were proved by pathology and immmunohistochemistry. All cases were performed operations. 5 underwent single surgery. 4 underwent surgery plus adjuvant radiotherapy. 4 underwent surgery plus adjuvant radiotherapy chemotherapy. 5 underwent surgery plus adjuvant chemoradiation. RESULT: All cases were followed up for a period of 1 to 7 years after operation. Twelve patients died of tumor until the last follow-up, meanwhile 6 patients stayed alive. In Six cases recurrence occurred. In five casescervical lymph node metastasis occurred, of which 3 cases received neck dissection and 2 cases received chemotherapy and radiotherapy due to no surgical indications. In three cases distant metastasis oc- curred. CONCLUSION Sinonasal mucosal malignant melanoma is rare and highly heterogenous. Current diagnosis depends on clinical characteristics and immunohistochemical examination. It still should be differentially diagnosed from other tumors. CT and MRI image examination can provide some helpful information to understand the extent and nature of lesions. The treatment of nasal endoscopic or the surgery under endoscopy has become to be a safe, viable and reasonable alternative to open resection. Appropriate indication must be carefully selected for these lesions.
