The present paper reports a systematic research of the antifatigue effect of Flammulina velutipes. The antifatigue effect was judged by the examination of serum lactate dchydrogenase activity, level of blood lactic acid, serum urea nitrogen, muscle and liver glycogen,The experiments indicated that feeding Flammulina velutipes to mice for several days the lactate dehydrogenase activity, muscle and liver glycogeu levels were significantly higher than that of the control. After exercise, the levels of blood lactate and serum urea nitrogen were significantly lower than those of control. After exercise, the recovery rate of lactic acid was much faster than that of control.From the above results, we concluded the Flammulina velutipes may have significant effect on the capability of adaptation to heavy exercise and prevention or elimination of fatigue after exercise.

Objective To investigate the effects of right or left transaction of cervical sympathetic trunk (TCST) on left ventricalar remodeling (LVRM) after acute myocardial infarction in rats and the mechanism. Methods Sixty-four adult mule pathogen-free SD rats (230-250 g) were randomly divided into 4 groups (n=16 each): group Ⅰsham operation (group S) ; group Ⅱ LVRM; group Ⅲ left TCST and group Ⅳ right TCST. Myocardial infarct was induced by ligation of left anterior descending branch (LAD) of coronary artery in group Ⅱ, Ⅲ and Ⅳ. Left and right TCST were performed immediately after myocardial infarct was successfully induced in group Ⅲ and Ⅳ respectively. In group S LAD and cervical sympathetic trunk were exposed but not ligated and transected. The animals were killed at 4 weeks after ligation of LAD and TCST. The weight of left ventricle was measured and left ventricle weight index calculated, Left veatricular myocardial tissue volume (V_t), the volume density of myocardial cells (V_v) and myocardial cell volmne (V_c) were quantitatively analyzed by stereological method. The c-fos mRNA expression in myocardium was determined by RT-PCR. Results The left ventricle weight index, V_t, V_c and c-fos mRNA expression were significantly increased in group LVRM (Ⅱ), left and right TCST (Ⅲ, Ⅳ) as compared with group S. Left ventricle weight index, V_v, V_t, V_c and c-fos mRNA expression were all significantly decreased in fight TCST group (Ⅳ), while left ventricle weight index, V_t, V_c and c-fos mRNA expression were significantly increased in left TCST group (Ⅲ) as compared with LVRM group (Ⅱ). Conclusion Right TCST down-regulates the increase in c-fos mRNA expression after acute myocardial infarction and inhibits the left ventricular remodeling while left TCST up-regulates the c-fos mRNA expression and promotes the development of left ventricular remodeling.

Objective : To analyze the trend of lung cancer incidence in Shaoxing, Zhejiang Province from 2014 to 2019, so as to provide the basis for lung cancer prevention and control. Methods : The data of lung cancer were collected through the information management system of chronic disease surveillance in Zhejiang Province.The crude incidence rate, age-standardized incidence rates by Chinese standard population ( ASIRC ) and by world standard population ( ASIRW ), truncated rate ( 35-64 ) years old ), and cumulative rate (0-74 years old) were calculated. The annual percentage change ( APC ) was used to analyze the trend of lung cancer. The annual contribution rate was used to analyze the contribution of the incidence trend with age to the total trend. Results : Totally 22 261 cases of lung cancer were reported in Shaoxing from 2014 to 2019. The crude incidence rate, ASIRC, ASIRW, truncated rate ( 35-64 years old ), and cumulative rate ( 0-74 years old ) were 83.51/100 000, 41.28/100 000, 41.01/100 000, 57.00/100 000 and 5.11%, respectively. The crude incidence rate, ASIRC and ASIRW increased significantly from 2014 to 2019, with the APC values of 8.56%, 6.42% and 6.05%, respectively ( P<0.05 ). The crude incidence rate, ASIRC, ASIRW, truncated rate ( 35-64 years old ), and cumulative rate ( 0-74 years old ) of man were 105.25/100 000, 48.09/100 000, 50.69/100 000, 62.03/100 000 and 6.42%, respectively, which were higher than those of women ( 61.84/100 000, 33.05/100 000, 31.35/100 000, 51.71/100 000 and 3.76% ).The crude incidence rate increased with age. The annual contribution rates of lung cancer incidence in people aged 15-<45 years, 45-<55 years, 55-<65 years and ≥65 years were 51.20%, 30.86%, 15.79% and 2.15%, respectively. The crude incidence rate in people aged 15-<45 years, 45-<55 years and 55-<65 years increased significantly from 2014 to 2019, with the APC values of 23.84%, 13.79% and 6.78%, respectively ( P<0.05 ). Conclusion From 2014 to 2019, the incidence of lung cancer in Shaoxing shows an increasing trend, and the age of onset is getting younger.

Objective:To explore the clinical effect of negative pressure wound therapy and to discuss the ethi-cal issues in this therapy and seek a solution. Methods:Sixty patients with negative pressure wound therapy in our hospital were invited to participate in this study. Patients were all with deep pressure ulcers or diabetic foot, of which the Wagner Scores were graded as three or four. They were divided into two groups randomly. The subjects in control group received standard treatment, while those in experimental group were treated by self -designed closed negative pressure drainage settings. The wound healing time, the cost of the treatment and comfort were compared between the two groups. Results:The cost of wound care in the experimental group was less than those in the control group (P<0. 001). There was no significant difference in comfort between two groups (P>0. 05). But the wound healing time was longer in the experimental group than those in the control group. Conclusion:Self-designed closed negative pressure settings can decrease the cost of patient care with the equal patient comfort and acceptance as the standard negative pressure, however, the wound healing time has been extended. So before using negative pressure technique, the medical staff should comprehensively analyze, be guided by medical ethics and choose the appropriate treatment for different patients.

Objective To investigate the effect of parecoxib on cardiac function after acute myocardial infarction (AMI) in rats. Methods Twenty-four adult male SD rats, weighing 230-250 g, were randomly divided into 3 groups ( n = 8 each): group Ⅰ sham operation (group S), group Ⅱ AMI and group Ⅲ parecoxib (group P). Myocardial infarction was induced by ligation of left anterior descending branch (LAD) of coronary artery in group Ⅱ and Ⅲ . In group S, LAD and cervical sympathetic trunk were exposed but not ligated and transected.Group P received intrperitoneal parecoxib 8 mg/kg once a day for 3 days 24 h after ligation of LAD, while group AMI received normal saline instead. At 4th day after ligation LAD, the left ventricular systolic pressure ( LVSP),left ventricular end-diastolic pressure (LVEDP) and ± dp/dtmax were measured and recorded. Blood samples were taken from common carotid artery to determine the plasma concentrations of TXA2 and PGI2 and PGI2/TXA2 was calculated. Then the animals were sacrificed and hearts removed. Myocardial infarct size of left venicle was calculated. Results Compared with group S, LVSP, ± dp/dtmax, plasma concentrations of PGI2 and PGI2/TXA2 were significantly decreased, while LVEDP and plasma concentrations of TXA2 increased in group AMI and P( P ＜0.05). Compared with group AMI, LVSP, ± dp/dtmax, plasma concentrations of PGI2 and PGI2/TXA2 were significantly decreased, while LVEDP and plasma concentrations of TXA2 increased in group P ( P ＜ 0.05). There was no significant difference in myocardial infarct size between group AMI and P (P ＞ 0.05). Conclusion Parecoxib can improve cardiac function after AMI in rats and the mechanism is related to regulation of the balance of PGI2/TXA2.
