Objective To investigate the effects of intra-articular hyaluronan(HA)injection on the expression of cartilage oligomeric matrix protein(COMP)in synovium of strenuous running rats,and investigate the possibility of predicting the effectiveness of HA based on COMP in synovium.Methods 36 healthy male Wistar rats were randomly divided into control group,strenuous running group and strenuous running group and HA injection group.Strenuous running group and HA injection group were intra- articularly injected with HA once a week for 5 consecutive weeks.The histological changes of synovium of knee joint was examined by H.E.staining and immunohistochemical expression of COMP in three groups after 6 weeks' strenuous running.Results Synovial inflammation was less severe in strenuous running and HA injection group than strenuous running group(t =7.15,P ＜0.01).The immunohistochemical expression of COMP in rats'synovium of knee joint in strenuous running and HA injection group was significantly lower than that in rats'synovium in strenuous running group(t = 6.30,P ＜ 0.01).Conclusions Intra- articular HA injection suppressed synovitis,and the expression of COMP in synovium could be used to predict the effectiveness of HA.

Objective To probe into the relation of expressions of HIF-1α, VEGF and EGFR in esophageal squamous cell carcinoma with radiation therapy efficacy. Methods 73 of the patients with carcinoma of oesophagus from January , 2011 to May , 2014 in the General Hospital of Ningxia Medical University , were involved in this research , their clinical data reviewed and analyzed. Before radiotherapy , immunohistochemical SP was used to test expressions of HIF-1α, VEGF and EGFR in the cancer tissues. Relationships between the expressions and the efficiency of radiotherapy were analyzed. Results The positive expressions of HIF-1α, VEGF and EGFR were 70.0%, 84.9% and 80.8%, respectively. In terms of the single factor analysis related to recent curative effects, HIF-1α expression had significant correlation with recent curative effects (P=0.03). Conversely , multiplicity indicated that HIF-1α and EGFR expressions were notably associated with recent curative effects (P=0.007, 0.045, respectively). Conclusions The positive expressions of HIF-1α,VEGF and EGFR in the esophageal carcinoma may account for a largest proportion of the total. HIF-1α and EGFR expressions are associated with the short-term outcomes.

Objective To observe any effect of intensive training on the degree of depression and the expression of Kalirin-7 in the hippocampus of rats modeling with post-stroke depression,and to investigatc possible mechanisms.Methods Forty male Wistar rats were randomly divided into a post-stroke depression (PSD) group,a routine training group,an intensive training group and a sham-operation group (n =10 for each group).All except the sham-operation group were given the middle cerebral artery occlusion using the intraluminal thread method,and chronic mild stress was applied.The PSD group and the sham-operation group were not given any training.The routine training group was trained oncc a day,and the intensive training group was trained twice a day.The sucrose preference test,open field test and forced swimming test were conducted at the outset and after 14 and 28 days of training.The expression of Kalirin-7 in the left hippocampus was detected using Western blotting.Results After 14 days of training,significant differences were found in the test results of the sham-operation group compared with the other groups (P＜0.05).There were also significant differences in the average results on all 3 tests among all of the groups except the sham-operation group.At both 14 and 28 days after training,the average expression of Kalirin-7 in both the routine and intensive training groups was significantly higher than in the PSD group (P＜0.05),and that of the intensive training group was significantly higher than that of the routine training group at the same time points (P＜0.05).Conclusion Intensive training can relieve depression and increase the expression of the Kalirin-7 in the hippocampus,at least in rats.

Objective To characterize the changes in the dimensions during systolic and diastolic periods in the aorta with ECG-gated multi-detector CTA scans.Methods The CT angiograms of 115 patients (78 males,mean age 55.2 ± 9.4 years;37 females,mean age 60.1 ± 8.5 years) both in systolic and diastolic periods were obtained on a 64-slice ECG-gated multi-detector CT scanner.The diameters were measured at four anatomic levels of the aorta.(Level A:1 mm proximal to the innominate artery;Level B:1 mm distal to the left common carotid artery;Level C:1 mm distal to the left subclavian artery;Level D:10cm distal to the left subclavian artery).On each level,the maximal and the minimal diameters were measured both in systolic and diastolic periods.Results The paired sample t test results showed a significant difference between the systolic and diastolic diameters in all individual subjects on every level (P ＜0.001).The mean maximum diameter changes were 1.95％ (range-2.0％ to 7.0％),2.12％ (range-3.0％ to 6.0％),1.88％(range-1.0％ to 8.0％)and2.47％(range-3.0％ to 10.0％)at level A,B,C and D,respectively.The mean minimum diameter changes were 1.43％ (range-3.0％ to 5.0％),2.67％ (range-2.0％ to 11.0％),1.75％ (range-14.0％ to 9.0％)and 2.99％ (range -2.0％ to 11.0％) at level A,B,C and D,respectively.Conclusions The differences of the aortic diameters between systolic and diastolic periods are significant.The pulsatility of aorta in Chinese population may be different from published Western literature.

In order to optimize acupuncture treatment protocol for functional defecation disorders, literature during past 20 years is reviewed, and factors which influences acupuncture therapeutic effect are analyzed from aspects of acupoint, acupuncture technique, etc. As for the selection of acupoint, more attention should be paid on the use of Baliao, especially Zhongliao (BL 33) and Xialiao (BL 34); when Baliao is deeply needled, it is essential to acquire scientific technique. The relationship between acupuncture parameter (including electroacupuncture waveform and frequency), acupuncture techniques (including reinforcing and reducing technique, quantity of stimulation, etc. ) and acupuncture efficacy is complicated, and the scientific values of present research conclusion are in need, of further improvement. The diagnosis and treatment awareness on types of functional defecation should be strengthened, and the mental health of the constipation patients should be concerned. The combination of acupuncture and biofeedback training can have a synergistic effect, which is benefit to achieve a better long-term effect. Based on this, acupuncture treatment protocol for functional defecation disorders can be optimized to further improve the efficacy.

Available antidepressants are based on the tricyclic and monoamine oxidase inhibitor which were discovered more than sixteen years ago.These antidepressants were found to promote serotonin or noradrenaline function in the brain to produce a antidepressant effect.Although newer agents are more specific,but unfortunately,the issues of slower effect,low-response rate and side-effect are still unsolved.Cordycepin is the main effective component of Cordyceps Militaris which has been used as a Chinese herb and food for hundreds of years.This review summarizes the antidepressant effect and the involved mechanisms of Cordycepin,and provides a novel concept on the research and development of antidepressants by using Chinese herb.

Objective To evaluate the efficacy and safety of short-term sensor-augmented insulin-pump (SAP) therapy for poorly controlled patients with type 1 diabetes mellitus (T1DM).Methods Sixty T1DM patients with glycosylated hemoglobin (HbA1c)>9.0% were randomly assigned to 2 groups treated with SAP or multiple daily insulin injection ( MDI) for 6 days, then all patients converted to MDI therapy. Results Compared with MDI group and before therapy, the mean blood glucose concentration ( MBG) , SD of blood glucose, mean amplitude of glycemic excursion ( MAGE) and 24-h area under curve at 10.0 ( AUC10.0 ) levels in SAP group significantly decreased after 6-day therapy ( compared with MDI group:t=1.761,P=0.028, t=2.569,P=0.037, t=2.712,P=0.020, t=2.985,P=0.014, compared with before therapy:t=3.128,P=0.006, t=2.689,P=0.024, t=2.966,P=0.013, t=3.076,P=0.009);while there was no difference in 24-h area under curve at 3.9 (AUC3.9) between groups (P>0.05).After 1 month follow-up HbA1c levels decreased in SAP group (t=2.344,P=0.023) and were significantly lower than those in MDI group (t=1.844, P=0.035).There was no difference in daily insulin dosage, fasting C peptide (FCP) and postprandial 2h C peptide (2hCP) between two groups (P>0.05).Age (t=2.125, P=0.012) and SAP therapy (t=3.376, P=0.009) were independently correlated with the HbA1c after 1 month.Conclusion Short-term SAP therapy is effective and safe for poorly controlled T1DM patients with rapid glucose lowering and glycemic excursions reduction.

Objective: To explore the relationship between the muscle mass index (MMI) and the aggregation of cardiovascular risk factors (CVRFs) in children and adolescents, and to provide a scientific basis for the prevention and treatment of cardiovascular diseases in children and adolescents. Methods: The current situation study design was adopted, and 1 622 children and adolescents aged 12-17 years old in Yinchuan City were selected by a cluster random sampling method. All subjects were subjected to questionnaire survey, physical examination, body composition determination and laboratory index testing. Results: When other variables were not adjusted, MMI was a risk factor for the aggregation of cardiovascular risk factors ( P <0.01). After adjusting for age, gender and BMI, MMI became a protective factor for CVRFs≥1 ( OR =0.74, 95% CI =0.62-0.89), compared with insufficient MMI, the risk of developing CVRFs≥1 with good MMI and sufficient MMI was 0.60(95% CI =0.46-0.79), 0.56(95% CI =0.37- 0.85 ) times. The risk of CVRFs≥2 was 0.54(95% CI =0.37-0.79), 0.51(95% CI =0.30-0.87) times, and similar results were found in boys ( P <0.05). Conclusion Under the same BMI level, muscle mass index is a protective factor for cardiovascular risk factor aggregation in children and adolescents. Physical exercise of children and adolescents should be emphasized to maintain the best muscle mass and weight.

Objective: To analyze the interaction of fat mass (FM) and fat free mass (FFM) on the aggregation of cardiovascular disease risk factors (CVRFs) among children and adolescents in Yinchuan City, China, so as to provide scientific basis for the prevention of CVRFs and cardiovascular disease in children and adolescents. Methods: A total of 1 822 children and adolescents aged 12 to 18 years in Yinchuan City were randomly selected for questionnaire survey, physical examination, body composition assessment and laboratory tests, through a cluster sampling method from 2017 to 2020. Binary Logistic regression was used to analyze the relationship between FM, FFM and the aggregation of CVRFs, and their interaction was analyzed. Results: After adjusting for sex and age, the risk of having CVRFs aggregation ≥1 in high FM and low FFM group and high FM and high FFM group was 2.01(95% CI =1.46-2.77) and 3.64(95% CI =2.66-4.98) times higher than that in low FM and low FFM group, and the risk of having CVRFs aggregation ≥2 was 1.67(95% CI =1.06-2.63) and 4.20 (95% CI =2.76-6.38) times, respectively( P <0.05). There was a multiplicative interaction between FM and FFM, which increased the risk of CVRFs aggregration ≥1 and ≥2. The adjusted OR and 95% CI were 1.58(1.04-2.40) and 1.95(1.12-3.42), respectively( P <0.05). Conclusion The results indicated the additive and multiplicative interactions between high levels of fat mass and fat free mass on the aggregation of cardiovascular risk factors, which increased the risk of aggregation of cardiovascular risk factors.

Objective: To investigate the relationship between hypertriglyceridemic waist (HTW) phenotype and abnormal blood pressure in children and adolescents in Yinchuan City, Ningxia, and to provide scientific basis for early identification and prevention of hypertension. Methods: A cluster sampling method was adopted to select 1 566 children and adolescents in Yinchuan. All participants completed questionnaire survey, physical measurement and biochemical examination. Results: In general, after adjusting for age, smoking, drinking, and family history of hypertension, compared with the normal triglyceride normal waist (NWNT) phenotype, the enlarged waist (EW) and HTW phenotypes both increased the risk of abnormal blood pressure ( OR EW =2.62, 95% CI =1.87-3.67; OR HTW =3.97, 95% CI =2.30-6.86); the risk of abnormal blood pressure in boys with EW and HTW phenotypes was that of boys with NTNW phenotype, respectively 3.80 times (95% CI =2.35-6.15) and 3.32 times (95% CI =1.59-6.92) of girls EW and HTW phenotypes. The risk of abnormal blood pressure in girls with EW and HTW phenotypes was that of girls with NTNW phenotype, respectively 1.72 times (95% CI =1.06-2.82) and 4.62 times(95% CI =1.97-10.85). Conclusion The hypertriglyceridemic waist phenotypes among children and adolescents in Yinchuan is significantly correlated with increased risk of abnormal blood pressure. More attention should be paid to triglyceride level and waist circumference among children and adolescents.
