Objective: To study correlation between plasma mitochondrial coupling factor-6 (MCF-6) level in coronary circulation and coronary stenotic degree in CHD patients. Methods: A total of 64 CHD patients were selected as CHD group, and they were further divided into single-vessel group, double-vessel group and multi-vessel coronary disease group; another 20 cases with normal coronary artery were enrolled as normal control group. Radioimmunoassay method was used to measure plasma MCF-6 concentration in peripheral, coronary sinus and aortic root in each group. Multivariant linear gradual regressive analysis was used to analyze above-mentioned correlation. Results: Compared with normal control group, there was significant increase in plasma MCF-6 concentration in peripheral, aortic root and coronary sinus in CHD patients (P<0.05 all) ；compared with aortic root and peripheral plasma, there was significant increase in MCF-6 concentration [(348±48) pg/ml vs. (340±51) pg/ml vs. (402±56) pg/ml, P<0.01 all] in coronary sinus of CHD group；Compared with single-vessel group, double-vessel group, there were increase in MCF-6 concentration in multi-vessel coronary disease group (P<0.05～0.01); Multivariant linear gradual regressive analysis indicated that Gensini score was significant positively correlated with plasma MCF-6 concentrations in coronary sinus and aortic root (r=0.650, P<0.01; r=0.711, P<0.01). Conclusion: Mitochondrial coupling factor-6 participates in the pathophysiological process of coronary heart disease, which may be an important vasoactive substance during development of coronary heart disease.

Objective To investigate the effects of Zafirlukast on emotions and Th1/Th2 cytokines in asthmatic children.Methods One hundred and eight asthmatic children were randomly allocated to 3 groups.The children in group A inhaled Pulmicort aerosol 200 ?g twice every day.On the basis of inhaled Pulmicort aerosol,the children in group B took orally Zafirlukast orally 10 mg once every day.The children in group C only took orally Zafirlukast 10 mg once every day.The course of treatment of all children were 4 weeks.Anxiety,depression status and the levels of IFN-? and IL-4 in blood serum were respectively detected before and after treatment.Results Scores of anxiety and depression after treatment in 3 groups were significantly lower than those before treatment(Pa0.05).Conclusions Zafirlukast or Glucocorticoid inhalation has the same effect on improving emotional status and accommodating disequilibrium of Th1/Th2 for asthmatic children,but effect of Zafirlukast combined with Glucocorticoid inhalation are better.

Objective To evaluate the changes of reticulated platelets (RP)in diagnosis and treatment of idiopathic thrombocytopenic purpura (ITP). Methods RPs were measured by flow cytometry and the percentage and absolute counts of RPs were calcula- ted in ITP group,non-ITP group and control group.Results Compared with control group,ITP group had a significantly high percentage and low absolute counts of RPs (P

OBJECTIVETo measure the levels of urinary prostaglandins E2 (PGE2) in benign prostatic hyperplasia (BPH) patients with or without overactive bladder (OAB) symptoms and determine whether urinary PGE2 can serve as a biomarker for BPH-related OAB.

METHODSThis study included 86 BPH patients and 34 male control subjects without lower urinary tract symptoms. Based on the OAB symptom scores (OABSS), the BPH cases were classified as BPH/OAB (n =49) and BPH/non-OAB (n = 37) to be treated orally with tamsulosin alone and tamsulosin + tolterodine-tartrate, respectively, for 12 weeks. We measured the urinary PGE2 levels of all the subjects by ELISA before and after medication, the total PGE2 level normalized to the concentration of the urinary creatinine (PGE2/Cr). We also obtained the residual urine volume, Qmax, prostate volume, PSA level, IPSS and OABSS of the BPH patients, and compared them among different groups.

RESULTSThe baseline PGE2/Cr level was significantly lower in the control than in the BPH/OAB and BPH/non-OAB groups (both P <0.05), and higher in the BPH/OAB than in the BPH/non-OAB patients (P <0.05). After 12 weeks'treatment, the urinary PGE2/Cr level was remarkably decreased with relief of the OAB symptoms in the BPH/OAB patients (P <0.05) , but not in the BPH/non-OAB group (P >0.05). The concentration of PGE2 was not correlated with the IPSS storage score and OABSS of the BPH/OAB patients (P >0.05).

CONCLUSIONPatients with BPH/OAB have significantly higher urinary PGE2/Cr levels than those with BPH/non-OAB and normal controls, which tend to decrease with the alleviation of OAB symptoms. Our findings suggest that urinary PGE2 can be a potential biomarker for BPH/OAB.

AIM: To compare the efficiency and safety of torsional phacoemulsification with or without intelligent phacoemulsification ( IP ) software in hard nucleus cataract extraction.
METHODS: Ninety two eyes with Ⅳ - Ⅴ grades cataracts were enrolled in this randomized prospective study. Operated eyes were divided into two groups -those operated without IP software ( non- IP group, n =43) and those operated using IP software (IP group, n =49 ). The two groups were compared in terms of ultrasound time (UST) and cumulative dissipated energy (CDE). Post- operative outcome measures included the corneal edema and best-corrected visual acuity (BCVA) at 1,7d and 3mo postoperatively, corneal endothelial cell density and percentage of hexagonal cell at 7d and 3mo postoperatively.
RESULTS: UST was measured as 52. 51±9. 64s in non-IP Group and 48. 79±7. 13s in IP Group (P = 0. 030). CDE was 15. 78±3. 73% in non-IP Group and 14. 29±2. 77% in IP Group ( P = 0. 026). At the first postoperative day, the rate of BCVA>0. 1 in non-IP Group was 56%, and the rate in IP Group was 79% (P= 0. 066). Corneal edema in non-IP Group was 2. 98±0. 77 scores, and in IP Group it was 2. 61±0. 64 scores (P = 0. 021). At the postoperative 7 and 30d, the BCVA and corneal edema were no differences between two groups. At the postoperative 7d, corneal endothelial cell density in non- IP Group were 2497. 95 ±211. 48 / mm2 , less than 2586. 26±154. 71 / mm 2 in IP Group (P= 0. 029);percentage of hexagonal cell in IP group was 48. 33±8. 69%,higher than 44. 19±9. 48% of non-IP group(P= 0. 030).CONCLUSION: In hard nucleus cataract extraction, the IP software can combine the advantages of the two kinds of ultrasonic modes, which is more effective with lower ultrasound energy and less injury for the corneal endothclium, and is helpful for the recovery of vision at early stage after surgeries.

The incidence rate of thyroid cancer is increasing very rapidly during the past years.131I treatment for DTC is an effective method.However,DTC refractory to 131I treatment or therapeutic failure is not uncommon.High level expression of nuclear factor-kappa B (NF-λB) in thyroid cancer is closely related with carcinogenesis,progression,anti-apoptosis and therapeutic resistance.NF-κB inhibitor was effective for the treatment of thyroid cancer.Combined NF-κB inhibitor with131I may improve the therapeutic efficacy.
