BACKGROUND:Exercise can elicit generation of coronary col ateral circulation through numerous pro-angiogenic growth factors. It is not enough via a single factor to clearly definite signaling pathways for the generation of col ateral circulation. Many pro-angiogenic growth factors are involved in kal ikrein-kinin system, and there is no report about exercise effects on this system.
OBJECTIVE:To study effects of exercise training on bradykinin expression in rats with myocardial infarction.
METHODS:Thirty Wistar rats were randomly assigned to control group, myocardial infarction group and exercises training group. Rats in the control group were subjected to thoracotomy with no coronary artery ligation. Rats in the other two groups were modeled. In the exercise training group, 3 days after myocardial infarction, rats were subjected to 30-minute exercise training on treadmil , once a day for 4 weeks. At the terminal of the experiment, blood samples were obtained to analyze bradykinin expression by enzyme linked immunosorbent assay, and the myocardium was sampled to analyze relative blood flow by microsphere method.
RESULTS AND CONCLUSION:After exercise training, bradykinin level in the exercise training group was significantly higher than that in the myocardial infarction group (P<0.001). At the end of experiment, the relative blood flows of the exercise training and myocardial infarction groups were both increased compared with before experiment (P<0.05, P<0.001). At the end of experiment, the relative blood flow of the exercise training group was significantly higher than that of the myocardial infarction group (P<0.01). In al the three groups, bradykinin level was significantly correlated with the relative blood flow in the myocardium. These findings indicate exercises training can improve bradykinin expression apparently and increase blood flow in the myocardium, which il ustrates that the kal ikrein-kinin system plays an important role in exercise induced angiogenesis.

Keratorefractive surgery changes the central corneal thickness (CCT) and corneal curvature, which could influence the Goldmann applanation tonometer (GAT) and non-contact tonometer (NCT) measurements of intraocular pressure (IOP), but not dynamic contour tonometer(DCT). During the procedure of LASIK, there is a transient rise of IOP, which increases the risks of optic nerve damage. Meanwhile, the presence of functioning filtering blebs may affect the choice and outcome of refractive surgery, or even becomes a contraindication of surgery. Steroids are typically used after keratorefractive surgery, which could lead to IOP elevation. Hence it is important to monitor IOP after LASIK and to be aware of inaccurate IOP readings due to corneal flap interface fluid. Treating patients with postoperative elevated IOP after keratorefractive surgery is similar to that for patients with glaucoma. This review will address the issues surrounding the safety, relevant complications and implications of keratorefractive surgeries on glaucoma and relevant diagnostic tests.

Objective To investigate the relationship between alteration of gene in cyclic adenosine monophosphate(cAMP) signal transduction system in rats after myocardial damage and changes of cardiac function and ventricular remodeling. Methods Twenty eight male Wistar rats weighing 220 g to 250 g were randomly divided into three groups: acute myocardial damage group(AMD, n = 10), chronic myocardial damage group (CMD,n = 9 ) and sham-operation group (control, n = 9). Animal model of acute myocardial damage was established by ligation of rats left coronary artery in the AMD and the CMD groups. Rats in control group were treated similarly, except that the coronary suture was not tied. Hemodynamics and echocardiography were measured before rats were sacrificed 24 hours after operation in control and AMD groups but those in CMD groups were sacrificed 8 weeks later. Cadiocyte apoptosis were estimated by TUNEL method, cAMP levels in heart were tested by radioimmunity and the mRNA expressions for inducible cAMP early repressor (ICER), cAMP response element binding protein (CREB), phosphodiesterase 3A (PDE3A) and bcl-2 were assayed by real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR). Results The difference of left ventricular end diastolic diameter (LVEDD), left ventricular end diastolic pressure(LVEDP), maximal rising and falling rate of ventricular pressure,left ventricular systolic pressure (LVSP), eject fraction (EF) and fraction shortening (FS) were statistically significant among the three groups(F = 285.9, 196.8, 83.2, 80.4, 54.9, 196.6, 95.2, all P ＜ 0.01). LVEDD[(7.03 ±0.28), (8.20 ± 0.27)mm] and LVEDP[(11.19 ± 2.89), (19.76 ± 3.34)mmHg] in AMD and CMD groups were significantly increased, compared with those in control group[ (5.05 ± 0.30)mm, (- 5.62 ± 3.01 )mmHg, all P ＜0.01 ]. While maximal rising rate[ (2964 ± 449), (2214 ± 434)mmHg/s] and falling rate[(- 2617 ± 441),(- 1891± 424)mmHg/s] of left ventricular pressure, LVSP[ (94.19 ± 4.03), (85.85 ± 6.39)mmHg], EF[ (41.6 ±5.9)%, (35.9 ± 4.1 )%] and FS[ (36.9 ± 4.6)%, (23.1 ± 4.9)%] of left ventricular in the two groups were lower than those in control[(4759 ± 406)mmHg/s, (- 4327 ± 388)mmHg/s, (116.29 ± 8.25)mmHg, (80.9 ± 5.6)%,(53.1 ± 4.3)%, all P ＜ 0.01 ]. These changes in CMD group were more significant than those in AMD groups(P ＜0.05 or P ＜ 0.01 ). The difference of apoptotic index, cAMP and expression of ICER, CREB, PDE3A mRNA and bcl-2 mRNA were statistically significant among the three groups(F= 172.5, 141.0, 540.8, 246.8, 165.1, 563.9,all P＜ 0.01 ). Apoptotic index[ (32.8 ± 4.2)‰, (18.4 ± 3.9)‰] and cAMP in heart[ (9.95 ± 0.30), (5.60 ± 0.25)nmol/kg] in AMD and CMD groups were increased compared to control group[ (3.9 ± 1.7)‰, (2.48 ± 0.29)nmol/kg,all P ＜ 0.01 ], and those in CMD group were lower than in AMD group(all P ＜ 0.01 ). Expression of ICER mRNA (1.434 ± 0.093, 0.942 ± 0.076) and CREB mRNA(5.70 ± 0.50, 2.64 ± 0.51) in AMD and CMD groups were higher, and expression of PDE3A mRNA(48.98 ± 8.14, 16.68 ± 8.46) were lower than those in control group (0.154 ± 0.063, 1.08 ± 0.35, 105.94 ± 12.61, all P ＜ 0.01 ). The three genes in CMD group were fewer than those in AMD group(all P ＜ 0.01 ). bcl-2 mRNA was up regulated in AMD group(4.55 ± 0.27) and was down regulated in CMD group(0.35 ± 0.15) compared to control(2.18 ± 0.30, all P＜ 0.01). Conclusions There is PDE3A-ICER positive-feedback loop leading to myocyte apoptosis and heart failure after myocardial damage. The downregulation of PDE3A mRNA observed in chronic myocardial damage may play a causative role in the progression of ventricular remodeling and heart failure, in part, by inducing ICER mRNA and promoting cardiac myocyte dysfunction.

Objective To study the epidemiological characteristics of leprosy and to provide evidence for specific strategies development on leprosy control. Methods Descriptive analysis of data from the national leprosy surveillance system was carried out in 2009. Results A total number of 1597 new cases were detected in 2009 with a case detection rate of 0.120 per 100 000 population.The proportions of children under 15, multibacillary and disability grade 2 were 2.4%, 84.3% and 22.8% respectively. A total number of 148 relapse cases were reported in 2009, among which 69 cases were those relapsed after multi-drug therapy. The existing cases were 6603 by the end of 2009 with a prevalence rate of 0.049 per 10 000 populations, among which 3332 cases were on multi-drug therapy. Conclusion The overall leprosy situation is considered to be at low endemic in China but the distribution is unequal, with pocket areas in Yunnan, Sichuan and Guizhou. In order to reach the target on leprosy elimination, which was considered as a public health and social problem, the input and efforts are needed for many years to come.
