To establish neonatal rat cardiac fibroblast inflammatory secretion model by using LPS 100 microg x L(-1) combined with ATP 5 mmol x L(-1), in order to study the inhibitory effect of quercetin on the secretion of inflammatory factors TNF-alpha, IL-1beta and IL-6 of cardiac fibroblasts, further investigate the effect of quercetin on the protein expression of p-NF-kappaB p65 (S276) and p-Akt (S473) by western blot, and discuss the inhibitory effect of quercetin on the inflammatory secretion of cardiac fibroblasts. According to the findings, quercetin with the concentrations between 51.74 micromol x L(-1) and 827.81 micromol x L(-1) had no significant effect on the activity of cardiac fibroblasts. Quercetin with the concentrations of 82.78, 41.39, 20.70 micromol x L(-1) could notably inhibit the increase of TNF-alpha and IL-1beta induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 36 h (P < 0.01 or P < 0.05). Quercetin with the concentrations of 82.78, 41.39 micromol x L(-1) could notably inhibit the increase of IL-6 induced LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 36 h (P < 0.05), without any notable effect of quercetin with the concentration of 20.70 micromol x L(-1). Quercetin with the concentrations of 82.78, 41.39, 20. 70 micromol x L(-1) could notably inhibit the NF-kappaB p65 (S276) activation induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 15 min, with the most significant effect in 20.70 micromol x L(-1). Quercetin with the concentrations of 82.78, 41.39, 20.70 micromol x L(-1) could notably inhibit the increase of p-Akt(473) expression induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 240 min (P < 0.05). Therefore, this study believes that quercetin could attenuate the secretion of inflammatory factors TNF-alpha, IL-1beta and IL-6 of cardiac fibroblasts by inhibiting the activation of NF-kappaB p65 (S276) and Akt (473).

OBJECTIVETo investigate the method and effect of treatment of complex scapular body fractures by locking reconstructive plate through modified posterior approach.

METHODSFrom August 2005 to November 2009, 27 patients with complex scapula body fractures were treated by locking reconstruction bone plate fixation,including 19 males and 8 females with an average age of 36 years old ranging from 16 to 64 years. The time after injury was 0.5 hours to 11 days (averaged 3 days). Of all the patients, 9 cases were associated with ipsilateral clavicle fracture, 2 cases were associated with acromioclavicular joint dislocation,16 cases were associated with multiple rib fractures, 1 case were associated with humeral shaft fractures, 5 cases were associated with pleural effusion, atelectasis, lung contusion etc. After operating,shoulder functional recovery were followed up.

RESULTSTwenty-four patients were followed up from 2 to 35 months with an average of 19 months. According to Hardegger shoulder function,the results were excellent in 15 cases, good in 7 cases, general in 2 cases.

CONCLUSIONThis method had the advantage of less trauma and clear exposure, firm and reliable fixation, and early activities.

Objective:To observe the efficacy, median progression-free survival (PFS) and adverse reaction induced by rh-endostatin injection (Endostar) plus platin-based chemotherapy for advanced non-small cell lung cancer (NSCLC).Methods:Fifty five histologically or cytologically confirmed advanced NSCLC patients received Endostar combined with platin-based chemotherapy for more than 2 cycles. The evaluated parameters included PFS, response rate (RR), clinical benefit rate (CBR) and adverse reaction. Results:Of the 51 patients who can be evaluated for response, 15 (29.4%) achieved partial response (PR), 27 (52.9%) had stable disease (SD), 9 (17.6%) had progressive disease(PD), no patient had complete response(CR). The overall RR was 29.4% (15/51) and CBR was 82.4% (42/51). The median PFS was 6.3 months. There were no significant differences in the short-term efficacy and PFS between the patients who had different pathological features (P=0.037), those had naive or relapsed diseases (P=0.101), or those received different chemotherapeutic regimens (P=0.232). The total white cells and platelets decreased by 72.7% and 54.5%, respectively. The frequency of grade Ⅲ or Ⅳ neutropenia and thrombocytopenia were 36.4% (20 caces) and 21.8% (12 cases), respectively. Four patients stopped the therapy for adverse reaction. One died of gastrointestinal hemorrhage; one had uncontrolled grade Ⅲ hypertension; one had superventricular arrhythmia; one had grade Ⅳ hepatic dysfunction. Conclusion:The combination of Endostar and platin-based chemotherapy increased the CBR and prolonged the PFS of the patients with advanced NSCLC. The toxicities were tolerable.

Objective To investigate the expressions of carbohydrate antigen 19-9(CA19-9), carbohydrate antigen 15-3(CA15-3) and carbohydrate antigen 125(CA125) and their clinical significance in papillary thyroid carcinoma (PTC). Methods The expressions of CA19-9, CA15-3 and CA125 were detected by immunohistochemical MaxVision method in 80 cases of PTC and 80 cases of benign thyroid lesions (BTL), including 34 cases of nodular goiter, 26 cases of Hashimoto's thyroiditis and 20 cases of follicular adenoma. The relationship between expressions of CA19-9, CA15-3 and CA125 and the clinical pathological characteristics were analyzed. Results The expression rates of CA19-9, CA15-3 and CA125 in 80 cases of PTC were 85%, 100%and 43.8%respectively, compared with BTL, the difference was statistically significant (P < 0.01). There was no significant correlation between expressions of CA19-9, CA15-3 and CA125 and age, gender, number and diameter of tumor nodules, lymph node metastasis, and TNM staging (P > 0.05). The sensitivity of CA19-9, CA15-3 and CA125 in the differential diagnosis of PTC and BTL were 85%, 100% and 43.8% respectively, and the specificity were 91.3%, 36.3%and 91.3%, respectively. Conclusion The expressions of CA19-9, CA153 and CA125 are helpful for the differential diagnosis of PTC and BTL.

OBJECTIVETo investigate the clinical features of thyroid disease occurring in response to antiviral therapy in patients with chronic hepatitis C (CHC).

METHODSEighty-two patients diagnosed with CHC were recruited for study from our hospital between 2009 and 2010. All patients were given a 48-week course of antiviral combination therapy with pegylated-interferon (Peg-IFN; 180 mug qw ih) and ribavirin (RBV; 15 mg/kg bw). Patient sera was collected prior to treatment (baseline), at treatment weeks 24 and 48, and post-treatment week 24, and used to detect changes in levels of thyroid function markers, thyroid-specific and other autoantibodies, complement factors, and immunoglobulins (Igs). Differential expression of biomarkers was assessed between patients who developed thyroid disorder and those who did not.

RESULTSAt treatment week 48, 13.4% (11/82) of cases developed hypothyroidism, 3.7% (3/82) developed hyperthyroidism, 20.7% (17/82) tested positive for thyroglobulin antibody, and 22.0% (18/82) tested positive for thyroid peroxidase antibody. The patients who did not develop thyroid disease had significantly higher post-treatment levels (vs. baseline) of IgG (14.84 +/- 2.61 vs. 12.95 +/- 3.32 g/L, F = 10.458, P = 0.002) and C4 (0.26 +/- 0.09 vs. 0.22 +/- 0.08 g/L, F = 6.835, P = 0.011) and significantly lower IgM (0.86 +/- 0.48 vs. 1.00 +/- 0.42 g/L, F = 9.106, P = 0.003). The patients who developed thyroid disease showed no significant differences in the baseline and post-treatment levels of IgG, C4, or IgM. When the two groups of patients who did or did not develop thyroid disease were compared, there was no difference in the amount of patients who achieved sustained virological response.

CONCLUSIONAntiviral-induced thyroid disease in patients with refractory hepatitis C manifests as clinically-detectable abnormalities in serum levels of thyroid autoantibody and markers of hypothyroidism. Levels of other autoantibodies and Igs do not correlate with the development of thyroid disease in these patients, and thyroid disease does not appear to affect the efficacy of Peg-IFN + RBV antiviral therapy.

Objective To review the clinical diagnosis and treatment of acute focal renal infarction. Methods Three cases of focal renal infarction were reported and the literature was reviewed.The patients aged from 45 to 63 years with mean age of 54. Two cases had low back pain, 1 case with abdominal pain. Based on clinical history, B-ultrasonography and CT scan, focal renal infarction was diagnosed in 3 patients. There were 2 cases on left kidney and 1 case right. All cases were applied digital subtraction angiography (DSA) and thrombolytic anticoagulant therapy. Results Two cases received DSA and thrombolytic therapy. The other one case received pethidine 50 mg, progesterone 20 mg treatment, the salvia infusion and low molecular heparin 6000 U anticoagulant therapy. All patients had symtoms relieved after 1 d. A week later CT scan, 3 cases of renal infarction were apparently disappeared. Serum creatinine and urea nitrogen were normal. Three patients were followed, mean follow-up time was 1. 5 (0. 5-2) years. Conclusions The diagnosis of acute focal renal infarction mainly depends on B-ultrasound and CT. Early diagnosis and treatment is important for achieving recovery of the compromised renal function. Renal infarction should be suspected in the presence of abdominal pain of sudden onset.
