BACKGROUND:The power output of the human joints depends on the activation of agonists and antagonist muscles around the joints, and the antagonist muscle is involved in physical activity in a co-activated manner, thereby helping to maintain joint stability. But there are less reports on the central nervous system strategies of antagonist co-activation under different muscle contraction modes. OBJECTIVE:To observe the characteristics and differences of surface electromyography (sEMG) of agonists and antagonist muscles of the knee joints during maximal and submaximal isokinetic exercises until fatigue. METHODS:Sixteen students were enroled, who developed the right knee joint fatigue induced by the Biodex isokinetic equipment, and simultaneously sEMG activities of vastus medialis, vastus lateralis and biceps femoris were recorded by the myoelectrical equipment. The RMS (%) and mean frequency were selected to analyze sEMG characteristics. RESULTS AND CONCLUSION:In the maximal isokinetic fatigue, the peak torque was decreased by 40.3% (P < 0.05) and the sEMG activity of agonists gradualy increased and then declined, but the sEMG activity of antagonists kept constant. In the submaximal isokinetic fatigue, the peak torque was decreased by 40.0% (P < 0.05), the sEMG activity of agonists gradualy increased (P < 0.05), and however the sEMG activity of the antagonists initialy increased and then decreased. The RMS and mean frequency of vastus medialis and lateralis as antagonists at selected reciprocal contractions showed no significant changes (P > 0.05). These results suggest that in the different intensities of isokinetic fatigue, the central nervous system employs different neural strategies on agonists and antagonists.

Objective To explore the correlation between Helicobacter pylori (H.pylori) infection and colorectal cancer.Methods From January 2008 to January 2014,263 patients pathologically diagnosed as colorectal cancer were selected as colorectal cancer group,and at the same period 263 patients with normal colon mucosa under colonoscopy were set as control group.The rates of H.pylori infection,the rates of H.pylori infection in patients with different pathological types of colorectal cancer,the rates of H.pylori infection accompanied with atrophic gastritis and the rates of H.pylori infection accompanied with intestinal metaplasia of two groups were retrospectively analyzed.The difference of H.pylori infection between proximal colorectal cancer and distal colorectal cancer was compared.Chi-square test was performed for comparison and odds ratio (OR) value and 95％ confidence interval (CI) were calculated.Results Among 263 patients with colorectal cancer,the H.pylori infection rate of colorectal cancer group was 63.50％ (167/263),which was higher than that of control group (39.54％,104/263),and the difference was statistically significant (x2 =27.66,OR=2.66,95％ CI 1.85 to 3.83,P＜0.01).There was no statistical difference in rates of H.pylori infection among different pathological types of colorectal cancer (x2=0.15,P=0.93).The rate of H.pylori infection accompanied with atrophic gastritis in patients with colorectal cancer was 46.39％ (122/263) which was higher than that of control group (23.57％,62/263),and the difference was statistically significant (x2=28.53,OR=2.94,95％CI 1.98 to 4.36,P＜0.01).The rates of H.pylori infection accompanied with intestinal metaplasia in patients with colorectal cancer was 17.87％ (47/263) which was higher than that of control group (4.18％,11/263),and the difference was statistically significant (x2=23.56,OR=5.50,95％CI 2.76 to 10.95,P＜0.01).There was no significant difference in the rate of H.pylori infection between the proximal colorectal cancer and the distal colorectal cancer (x2 =1.48,P =0.22).Conclusion H.pylori infection,together with atrophic gastritis and intestinal metaplasia caused by it are correlated with colorectal cancer.

Objective To study and analyze the efficacy and adverse reactions of beraprost sodium combined with aspirin in the treatment of diabetic foot.Methods 90 cases with diabetic foot were selected and they were randomly divided into the observation group and control group,35 cases in each group.Two groups were both treated with basic treatment.On the basis of the basic treatment,the control group was given aspirin,while the observation group was treated with beraprost sodium combined with aspirin.The clinical efficacy,ulcer healing rate,ankle back index,transcutaneous oxygen pressure,average healing time and the occurrence of adverse reactions were compared between the two groups.Results The clinical effective rate of the observation group was 93.3％ (42/45),which was significantly higher than 84.4％ (38/45) of the control group,the difference between the two groups was statistically significant (x2 =8.030,P ＜ 0.05).The wound healing rate,ankle dorsal index,average healing time,the degree of improvement of transcutaneous and oxygen pressuer of the observation group were (81.4 ± 2.7) ％,(11.2 ± 2.1),(39.1 ± 2.1) d and (26.3 ± 1.8) mmHg,which were significantly better than (69.3 ± 1.9) ％,(8.4 ± 2.9) ％,(52.3 ± 8.2) d and (16.3 ± 2.6)mmHg of the control group.The differences of these indicators between the two groups were statistically significant(t =12.72,7.92,12.06,9.97,P ＜ 0.05).The difference of adverse reactions between the two groups was not statistically significant (P ＞ 0.05).Conclusion Beraprost sodium combined with aspirin has better clinical efficacy in the treatment of diabetic foot.It can improve the patients'ulcer healing rate,the ankle back index,transcutaneous oxygen pressure,shorter the average healing time,and it has few adverse reactions.

Objective To analyze whether tetramethylpyrazine could protect PC12 cells from injuries induced by caffeine,and to explore the mechanism of tetramethyipyrazine in the treatment of cerebral ischemia-reperfusion injury. Methods Caffeine was added to induce apoptosis of PC12 cells. Cytotoxicity was detected by CCK-8 assay. The electric potential of mitochondrial membrane was determined by flow cytometry. HMGB1 was detected by Western blotting. Oxidative stress was detected by ELISA. We observed toxicity of caffeine and the protective effects of tetramethylpyrazine. Results After the pre-treatment,tetramethylpyrazine significantly improved PC12 cell survival. Mitochondrial membrane potential was increased,the expression of HMGB1 decreased,SOD increased,LDH and MDA decreased,and GSH elevated. Conclusion Tetramethylpyrazine exerts a significant protective effect on PC12 cell injury caused by caffeine. The protective effect may be related to inhibition of apoptosis and regulation of the expression level of mediators involved in inflammation and oxidative stress.

Objective To explore the changes of indicators for total parenteral nutrition (TPN) and parenteral nutrition (PN) combining enteral nutrition (EN) support in patients with severe acute pancreatitis (SAP), and to analyze the treatment effects of two groups. Methods 29 patients with SAP were randomly divided into two groups: TPN group (n=14) and PN+EN group (n=15). Nonoperative treatment were applied to the two groups. The changes of indicators and therapeutic outcome of two groups were recorded after nutrition support 14 days. Results After 14 days nutritional support, serum albumin (ALB), total serum protein (TSP), blood calcium, glutamic-pyruvic transaminase (ALT), glutamic-oxaloacetic transaminase (AST) in each group increased significantly (P<0.05). While blood glucose, serum amylase, leucocyte count decreased significantly (P<0.05). However, there were no significant difference between two groups except leucocyte count in all laboratory tests. The leucocyte count in the PN+EN group was significantly lower than that in the TPN group (P<0.05). In both group there was no difference found in serum total bilirubin (TB) before and after nutrition support (P>0.05). The APACHE II scores, average hospital days, average hospital charges, incidence of infection and mortality rate in the PN+EN group were significantly lower than that in the TPN group (P<0.05). ConclusionsPN combining EN support was superior to TPN in the treatment of patients with SAP.
