Objective:To investigate the correlation of the blood concentration of tacrolimus ( Tac) and serum cystatin C ( SCysC) and serum creatinine (Scr) in the patients with renal transplantation. Methods:Totally 84 cases of renal transplantation patients (67 male/17 female) treated with Tac were involved. The blood concentration of Tac, SCysC and Scr were monitored after the operation. Data results were categorized according to the postoperative time and the blood concentration. The correlations of Tac blood concentra-tion,SCysC and Scr were analyzed and compared by using Pearson correlation analysis. Results: The blood concentration of Tac was not significantly associated with SCysC and Scr in different postoperative time groups and different drug concentration groups ( P >0. 05). As the extension of time,the blood concentration of Tac showed a gradual declining trend, while SCysC and Scr levels de-creased first, and then increased gradually after two years of the operation. Conclusion:The blood concentration of Tac has no effect on the function evaluation of transplanted kidney by the biochemical indicators such as SCysC and Scr.

BACKGROUND:Intra-articular injection of sodium hyaluronate is an effective method for the treatment of knee osteoarthritis, with significant effect and less adverse reactions, but the mechanism is unclear. OBJECTIVE:Through testing the malondialdehyde and superoxide dismutase levels in the synovial fluid of knee osteoarthritis before and after injection of sodium hyaluronate, to evaluate the clinical efficacy of sodium hyaluronate in the treatment of knee osteoarthritis. METHODS:Thirty-seven patients with knee osteoarthritis (40 knees) were enroled and divided into mild (n=10, 10 knees), moderate (n=17, 18 knees), and severe (n=10, 12 knees) groups according to the Japan's knee osteoarthritis indications. Patients were subjected to intra-articular injection of 25 mg sodium hyaluronate, once a week for 5 weeks. The levels of malondialdehyde and superoxide dismutase in the synovial fluid before and 4 weeks after treatment were detected, and then clinical effects were evaluated based on the clinical scores according to the Japan’s knee osteoarthritis indications. RESULTS AND CONCLUSION: The indication rating results of the mild and moderate groups were decreased significantly 4 weeks after injection (P < 0.05), but there were no significant difference in the severe group before and after treatment. The malondialdehyde level in the synovial fluid was decreased obviously in the three groups at 4 weeks after injection (P < 0.05), while the level of superoxide dismutase was increased remarkably (P < 0.05). These findings indicate that sodium hyaluronate can treat knee osteoarthritis by reducing the malondialdehyde level and increasing superoxide dismutase level in the synovial fluid, but this method is more suitable for treatment of mild to moderate knee osteoarthritis.

Objective: To observe the effect of Tuina (Chinese therapeutic massage) on creatine kinase (CK), mitochondrial Ca2+ concentration, and ultrastructure of skeletal muscle in delayed onset muscle soreness (DOMS) model rats.Methods: A total of 130 healthy male Sprague-Dawley rats were randomly divided into a blank group, an exercise control group, a pre-exercise Tuina group, and a post-exercise Tuina group. According to the time points for sample collection, the exercise control group was divided into a 0 h exercise control group, a 24 h exercise control group, a 48 h exercise control group, and a 72 h exercise control group; the pre-exercise Tuina group was further divided into a 0 h pre-exercise Tuina group, a 24 h pre-exercise Tuina group, a 48 h pre-exercise Tuina group, and a 72 h pre-exercise Tuina group; and the post-exercise Tuina group was divided into a 0 h post-exercise Tuina group, a 24 h post-exercise Tuina group, a 48 h post-exercise Tuina group, and a 72 h post-exercise Tuina group. Rats in all groups except for the blank group received DOMS modeling. Professionals performed Nie-Pinching manipulation and finger Nian-Twisting manipulation on the lower limbs of the rats. The samples were collected at 0 h, 24 h, 48 h, or 72 h after exhaustive exercise for each pre-exercise Tuina group. The samples were collected at 0 h, 24 h, 48 h, or 72 h after Tuina for each post-exercise Tuina group. The changes in serum CK, skeletal muscle mitochondrial Ca2+ concentration, and Ca2+-adenosine triphosphatase (ATPase) were determined. The ultrastructure changes of skeletal muscles in each group were observed by a transmission electron microscope. Results: The electron microscope showed that compared with the exercise control group, the skeletal muscle structures of the pre-exercise Tuina group and the post-exercise Tuina group were significantly improved, and the overall performance of skeletal muscle in the pre-exercise Tuina group was more similar to that of the blank group. The level of serum CK in the pre-exercise Tuina group and the post-exercise Tuina group was significantly lower than that in the exercise control group (P<0.01). The Ca2+ concentration of skeletal muscle in the 24 h, 48 h, and 72 h pre-exercise Tuina groups was lower than that in the post-exercise Tuina group at the same time point (P<0.01). The Ca2+-ATPase concentration of skeletal muscle in the 24 h and 72 h pre-exercise Tuina groups was lower than that in the post-exercise Tuina group at the same time point (P<0.05).Conclusion: Tuina effectively prevents muscle damage caused by heavy exercise and long-term exercise, which may be related to the increase of skeletal muscle Ca2+-ATPase activity and mitochondrial Ca2+ transport.

Future research and evaluation of the treatment methods for subhealth conditions from the perspective of traditional Chinese medicine (TCM) may provide an important direction for developing effective management of these conditions. Objective: To evaluate the efficacy and safety of Xiaopi Yishen herbal extract granules (XPYS-HEG), a compound traditional Chinese herbal medicine for relieving fatigue and promoting a cheerful spirit for the treatment of people with fatigue-predominant subhealth due to liver-qi stagnation and spleen-qi deficiency. Design, setting participants and interventions: A multi-center, randomized, double-blinded, placebo-controlled clinical study was undertaken. The study period was 18 weeks, including 6 weeks for intervention and 12 weeks for follow-up. Participants were recruited from medical center and outpatient clinics of three hospitals in China, i.e. Xiaotangshan Hospital of Beijing, the First Affiliated Hospital of Henan University of TCM and the Affiliated Hospital of Liaoning University of TCM. Two hundred participants who met the criteria of fatigue-predominant subhealth and liver-qi stagnation and spleen-qi deficiency in TCM were allocated randomly to the treatment group (XPYS, n=100) and control group (placebo, n=100). Main outcome measures: The total score of Fatigue Scale-14 (FS-14) was used to evaluate the fatigue status of subjects and the extent of liver-qi stagnation and spleen-qi deficiency syndrome was also recorded. Results: Three cases in the XPYS group withdrew from the trial. There were 200 subjects who entered to full analysis set (FAS) analysis and 197 subjects fitted in the per-protocol set (PPS) analysis. (1) According to the score changes of FS-14, the effectiveness rates in the XPYS and placebo group were as follows: 14.0% vs 9.0% (FAS) and 14.4% vs 9.0% (PPS) for complete remission, 19.0% vs 15.0% (FAS) and 19.6% vs 15.0% (PPS) for obvious effects, 39.0% vs 26.0% (FAS) and 39.2% vs 26.0% (PPS) for effective, and 72.0% vs 50.0% (FAS) and 73.2% vs 50.0% (PPS) for complete efficacy. The efficacy of XPYS-HEG was superior to the placebo statistically (P<0.05). (2) According to the score changes of TCM syndrome, the effectiveness rates in the XPYS group and placebo group were as follows: 1.0% vs 0.0% (FAS) and 1.0% vs 0.0% (PPS) for complete remission, 20.0% vs 7.0% (FAS) and 19.6% vs 7.0% (PPS) for obvious effects, 29.0% vs 24.0% (FAS) and 29.9% vs 24.0% (PPS) for effective, and 50.0% vs 31.0% (FAS) and 50.5% vs 31.0% (PPS) for complete efficacy. The efficacy of XPYS-HEG was superior to that of placebo statistically (P<0.05). (3) The follow-up results at 12 weeks and 18 weeks showed that the efficacy of XPYS-HEG was superior to that of placebo statistically (P<0.05). (4) No adverse effects were found in the XPYS group. Conclusion: It can be concluded that XPYS-HEG is effective and safe for the treatment of people with fatigue-predominant subhealth due to liver-qi stagnation and spleen-qi deficiency.

BACKGROUND:Clinical studies have shown that aerobic exercise is an important supplement to the clinical treatment of patients with pulmonary hypertension,which can alleviate the disease condition,increase exercise tolerance and improve the quality of life.However,it is not clear whether patients at different stages of pulmonary hypertension can benefit equally from exercise training. OBJECTIVE:To compare the intervention effects of early or late aerobic training on right heart failure in rats with pulmonary hypertension and explore its possible mechanism. METHODS:Sixty male Wistar rats were randomly divided into control group,model sedentary group,model early exercise group and model late exercise group,with 15 rats in each group.The model of pulmonary hypertension was established by intraperitoneal injection of monocrotaline(60 mg/kg)in the latter three groups.The model early exercise group was given 8 weeks of treadmill aerobic exercise(60%maximum running speed,60 minutes per day,5 days a week)after modeling,while the model late exercise group was trained for 6 weeks after 2 weeks of modeling.The control and model sedentary groups were fed quietly in the rat cage for 8 weeks.After training,the exercise performance,right ventricular hemodynamics,cardiopulmonary function,cardiopulmonary histopathology,reactive oxygen species level in mitochondria,activity of mitochondrial respiratory chain complex and expressions of myocardial tissue proteins were detected. RESULTS AND CONCLUSION:Compared with the model sedentary group,exercise performance and right ventricular function improved(P<0.05),myocardial collagen content,endothelin-1,tumor necrosis factor-α/interleukin-10 ratio and β-myosin heavy chain/α-myosin heavy chain ratio decreased(P<0.05),vascular endothelial growth factor and sarcoplasmic reticulum calcium-adenosine triphosphate enzyme expression increased(P<0.05),immunofluorescence intensity of mitochondrial reactive oxygen species and the protein expression of 3-nitrotyrosine decreased(P<0.05),the activities of complex I,II,IV and V increased in the model early exercise and model late exercise groups(P<0.05),but there were no significant changes in right ventricular maximum pressure,pulmonary acceleration time and pulmonary artery wall area/total vascular area ratio(P>0.05).Compared with the model late exercise group,the model early exercise group further improved exercise performance and right ventricular function,and downregulated collagen content,brain natriuretic peptide protein expression,tumor necrosis factor-α/interleukin-10 ratio and β-myosin heavy chain/α-myosin heavy chain ratio(P<0.05).To conclude,although pulmonary vascular remodeling and right ventricular overload persist in rats with pulmonary hypertension,exercise training at different stages of the disease has a cardioprotective effect.The mechanism is related to the improvement of cardiac remodeling,neurohormone system imbalance,inflammatory response and mitochondrial oxidative stress.Greater benefit is gained from initiating exercise in the early stage of the disease.

BACKGROUND:Aging is associated with increased susceptibility to cardiovascular disease,and mitochondrial dysfunction plays a key role in the pathogenesis of cardiovascular disease.Regular physical activity is beneficial to cardiovascular health and can prevent and treat chronic heart disease.However,the specific mechanism of mitochondria in the protective effect of exercise on the aging heart has not yet been clarified. OBJECTIVE:To explore the effect of aerobic exercise on cardiac pathological remodeling in aging rats and to investigate the possible mechanism of mitochondrial quality control system. METHODS:Sixty Wistar rats were randomly divided into young sedentary group(6 months old),old sedentary group(20 months old)and old exercise group(20 months old)with 20 rats in each group.Rats in the young sedentary and old sedentary groups were fed in cages for 12 weeks,while those in the old exercise group underwent moderate-intensity aerobic treadmill exercise(60%of the maximal running speed,slope 0°,60 minute per day,5 days per week)for 12 weeks.After the experiment,the heart was extracted for relevant indicator tests. RESULTS AND CONCLUSION:Cardiac morphology and myocardial histopathology:compared with the young sedentary group,the rats in the old sedentary group presented with concentric cardiac hypertrophy,myocardial fibrosis,myocardial cell apoptosis and loss,and cardiac diastolic dysfunction(P<0.05);compared with the old sedentary group,animals in the old exercise group showed reduced myocardial fibrosis and apoptosis rates,increased cell numbers,improved cardiac function(P<0.05),and a transition in cardiac phenotype from pathological to physiological hypertrophy.Mitochondrial function:compared with the young sedentary group,the generation rate of mitochondrial hydrogen peroxide increased(P<0.05),respiration rate and respiratory control ratio of state 3 and state 4 decreased(P<0.05),activities of respiratory chain complexes Ⅰ,Ⅱ and Ⅳ decreased(P<0.05),mitochondrial calcium retention capacity decreased(P<0.05),and mitochondrial permeability transition pore opening increased(P<0.05)in the old sedentary group.Compared with the old sedentary group,all of the above indicators were significantly improved in the old exercise group(P<0.05).Mitochondrial quality control:compared with the young sedentary group,mitochondrial biogenesis decreased(P<0.05),mitophagy activity increased(P<0.05),mitochondrial fusion reduced(P<0.05),and fission raised(P<0.05)in the old sedentary group;compared with the old sedentary group,mitochondrial biogenesis and mitophagy activity increased(P<0.05),mitochondrial fusion raised(P<0.05)and fission decreased(P<0.05)in the old exercise group.To conclude,regular aerobic exercises exert cardioprotective effects in aging rats by regulating the mitochondrial quality control system,thus reversing pathological cardiac remodeling and improving cardiac function.
