Objective To investigate the effect of Ulinastatin preconditioning on hyperthermia induced rat skeletal muscle injury and the possible mechanism. Methods Cultured skeletal muscle cells were divided into 7 groups: control group (Group C), as normal culture; hyperthermia treated group (Group H), in which cells were exposed to 42℃for 2 hours then transfered to normal culture; ulinastatin preconditioned group (Group U), which were only preconditioned 1 hour by the final concentration of ulinastatin at 1 250 U/mL; and four different concentration of ulinastatin preconditioned+hyperthermia treated groups (Group Ⅰ, Ⅱ, Ⅲ, Ⅳ), in which cells were preconditioned 1 hour by the final concentration of ulinastatin at 312 , 625, 1250, 2 500 U/mL, respectively. And then, all the four groups were exposed to 42℃for 2 hours. MTT assay and LDH leakage were performed to study the cytotoxicity. Superoxide dismutase (SOD) activity and malondialdehyde (MDA) formation were measured to reflect the activity of antioxidase. Results Compared with Group H, MTT value in ulinastatin preconditioned group in GroupⅠ, Ⅱ,Ⅲ, Ⅳsignificantly increased (P<0.05) LDH leakage significantly decreased (P<0.05). And the activity of SOD in cultured cells significantly increased (P < 0.05), the content of cellular MDA was also significantly decreased (P<0.05). But there were no significant difference among Group Ⅰ, Ⅱ,Ⅲ,Ⅳ(P>0.05). Conclusion Ulinastatin preconditioning may have protective effect against hyperthermia induced skeletal muscle injury and it may be related to its ability of inhibiting radical production and promoting radical scavenging.

An analytical method of fluorescent dye-labeled oligonucleotides was established by ion pair reversed phase high performance liquid chromatography(IP-RP-HPLC) which was improved by optimizing the effects of triethylamine-acetic acid(TEAA)(0-0.15 mol/L), pH(4.5-7.0) and gradient. Comparing the retention of 5, 10 and 15-mer unlabeled oligonucleotides with that of 5'-carboxyfluorescein(5'FAM) labeled oligonucleotides, the mechanism of fluorescent dye-labeled oligonucleotides retention was studied. In addition, TaqMan~(TM) probes as wellas other common fluorescent dye-labeled oligonucleotides were concerned. The results showed that the best resolution of different length fluorescent dye-labeled oligonucleotides was observed under the condition of 0.01 mol/L TEAA and pH 7.0. The retention behavior of fluorescent dye-labeled oligonucleotides was different from that of unlabeled oligonucleotides significantly, and therefore they can be separated completely. The results indicated that the retention of unlabeled oligonucleotides enhanced with the increase of the length of molecule. In contrast, the retention of fluorescent dye-labeled oligonucleotides was reduced with the increase of the length of molecule. For the hydrophobicity of fluorescent dyes made a great impact on the retention, a longer retention time the labeled oligonucleotides would take while the hydrophobicity of fluorescent dyes was higher. However, the effect of the hydrophobicity was limited as the length was increased to a certain level.

It was recently shown that several new synthetic 2-alkylsulfanyl-6-benzyl-3, 4-dihydropyrimidin-4(3H)-one (S-DABO) derivatives demonstrated anti-HIV-1 activity. Three of the derivatives namely RZK-4, RZK-5 and RZK-6 were used in this study to explore their inhibitory effects on a variety of HIV strains. These compounds at a concentration of 200 microg mL(-1) almost completely inhibited the activity of recombinant HIV-1 reverse transcriptase. All of the three compounds reduced replication of HIV-1 laboratory-derived strains, low-passage clinical isolated strain, and the drug resistant strain. In particular RZK-6 showed potent activity against the HIV-1 drug resistant strain. In general, the antiviral activities are similar in magnitude to nevirapine (NVP), which is a non-nucleoside reverse transcriptase inhibitor approved by FDA. The therapeutic indexes of these compounds were remarkable, ranging from 3704 to 38462 indicating extremely low cytotoxicity. These results suggest that the three S-DABO derivatives in this study have good potential for further development in anti-HIV-1 therapy. It may be particularly useful to target at the non-nucleoside reverse transcriptase inhibitors resistant HIV-1 strain.

Objective To investigate the relationship between lipid fluctuations of daily diet and insulin resistance in patients with type 2 diabetes mellitus(T2DM) with normal fasting lipid profile. Methods One hundred and ninety?eight cases patients with T2DM who were treated in the Endocrinology Department of the General Hospital of Benxi Iron and Steel Group Corporation from October 2012 to September 2014 were selected. Patients were divided into three groups according to fasting and postprandial 4 h triglyceride( TG4 h)
level,the group with normal fasting TG and normal TG4 h with 38 cases,the group with normal fasting TG and rising TG4 h with 78 cases,the group with rising fasting TG and rising TG4 h with 82 cases. The control group was composed of healthy volunteers with 20 cases. The patients followed daily diet habits to eat,blood glucose, insulin and lipid level of fasting and 2 h,4 h after lunch were monitored. Homeostasis model insulin resistance index( HOMA?IR) was used as an index to evaluate insulin resistance,and the correlation analysis was carried out with fasting and dietary intake of postprandial lipid metabolism. Results (1)HbA1c,FPG,HOMA?IR,TG and insulin level in the patients of the group with normal fasting TG and normal TG4 h,the group with normal fasting TG and rising TG4 h,the group with rising fasting TG and rising TG4 h were higher than the control group (HbA1c:(8. 4±1. 9)%,(8. 2±2. 4)%,(7. 8±1. 8)% vs. (4. 3±0. 6)%);FPG:(8. 98±1. 93) mmol/L, (8. 62±1. 33) mmol/L,(8. 28±1. 26) mmol/L vs. (4. 82±0. 63) mmol/L;,HOMA?IR:11. 07±0. 11,6. 98 ±0. 08,3. 83±0. 09 vs. 1. 24±0. 16;TG:0 h TG:(2. 35±1. 85) mmol/L,(1. 60±0. 41) mmol/L,(1. 58±0. 46) mmol/L vs. (0. 82±0. 25) mmol/L;2 h TG:(3. 97±2. 96) mmol/L,(2. 98±1. 49) mmol/L,(1. 83±0. 62) mmol/L vs. (1. 22±0. 31) mmol/L;4 h TG:(4. 24±1. 57) mmol/L,(3. 15±1. 63) mmol/L,(1. 92±0. 53) mmol/L vs. (1. 16±0. 24) mmol/L;insulin(0 h insulin:(26. 51±3. 65) mU/L,(18. 18±6. 24) mU/L,(10. 31 ±2. 38) mU/L vs. (5. 87±1. 62) mU/L;2 h insulin:(59. 15±8. 34) mU/L,(43. 75±9. 83) mU/L,(34. 27 ±1. 61) mU/L vs. (25. 24±1. 98) mU/L;4 h insulin:(51. 22±6. 79) mU/L,(40. 06±7. 51) mU/L,(31. 06 ±1.77) mU/L vs. (13.36±1.37) mU/L;P<0.05). (2)WHR(0.90±0.08 vs.0.72±0.06),HOMA?IR, insulin level of fasting and 2 h,4 h after lunch,TG of 2 h,4 h after lunch in the group with normal fasting TG and rising TG4 h were higher than the group with normal fasting TG and normal TG4 h ( P<0. 05 ) . ( 3 ) BMI ((27. 3±3. 3) kg/m2 vs. (23. 1±1. 5) kg/m2),WHR(0. 96±0. 10 vs. 0. 72±0. 06),HOMA?IR,TG and insulin level of fasting and 2 h,4 h after lunch in the group with rising fasting TG and rising TG4 h were higher than the group with normal fasting TG and normal TG4 h( P<0. 05) . HOMA?IR,TG and insulin level of fasting and 2 h, 4 h after lunch in the group with rising fasting TG and rising TG4 h were higher than the group with normal fasting TG and rising TG4 h( P<0. 05) . ( 4) HOMA?IR was positively correlated with BMI,WHR,and fasting TG levels in the groups with diabetes(r=0. 297,0. 376,0. 326,P<0. 05). HOMA?IR was significantly positively correlated with TG of 2 h,4 h after lunch in the groups with diabetes( r=0. 529,0. 693,P<0. 05) . HOMA?IR was significantly positively correlated with BMI and WHR in the control group(r=0. 617,0. 728,P <0. 05). HOMA?IR was not significantly correlated with fasting and postprandial TG in the control group. Conclusion Postprandial lipid metabolism disorder after daily diet is in some of patients with T2DM with normal fasting lipid profile. Postprandial lipid metabolism disorder after daily diet is significantly positively correlated with insulin resistance in patients with T2DM. Insulin resistance may be one of the pathogenesis of postprandial dyslipidemia in patients with type 2 diabetes.

Objective To study the changes of cardiac structure,heart function and pulmonary arterial pressure of the Han Chinese back to the plain after living long time on Tibetan Plateau. Methods Randomly choose 67 cases out of the Han people who have moved to the Tibetan Plateau many years , and been examined to make sure they have no disease caused by other factors. Examine their cardiac structure, heart function, pulmonary arterial pressure and valve flow velocity in Tibetan Plateau and about 60 days later back in plains respectively. Then make statistical analysis of high altitude cardiopulmonary adaptation and de-adaptation reaction according to the differences. Results Only were the values of pulmonary artery systolic pressure (PASP) and tricuspid regurgitation (TR) from the group back to plains lower than those from the group migrated to plateau (P = 0.045; P = 0.041). Other indicators of cardiac structure, heart function, pulmonary arterial pressure and valve flow velocity did not change significantly between the group back to plains and the group migrated to plateau (P > 0.05). Conclusions To Han people who returned to plains about 60 days later after long time staying on plateau , only the values of PASP and TR significantly reduce , which have not recovered to normal levels. This may be correlated with the ageing factor and long time migrating.

BACKGROUND:Moxibustion products produced in moxibustion, such as moxa smoke, are one of hotspots in moxibustion research. Metabonomics can be used to more comprehensively and systematicaly study the effects of moxibustion products on the body.
OBJECTIVE:To investigate the efect of diferent concentrations of moxibustion products on urine metabonomics of rats.
METHODS:Forty Sprague-Dawley rats were randomly divided into normal control group, low-dose moxibustion products group, middle-dose moxibustion products group, high-dose moxibustion products group, high-dose moxibustion products recovery group. In the latter four groups, rats from each group were exposed to the mixture of moxibustion products and pure gas at ratios of 0.4:2.0, 0.8:2.0, 1.6:2.0, 1.6:2.0, respectively, 4 hours daily, 5 days weekly, totaly for 60 days. After 60-day high-dose moxibustion products stimulation, rats in the high-dose moxibustion products recovery group were raised in normal air for 21 days. Rats in the normal control group were raised in normal air for 60 days without any moxibustion products. Then we analyzed the changes of urine metabonomics in al group rats.
RESULTS AND CONCLUSION: Totaly 108 metabolites were identified in the urine of rats using gas chromatography/time-of-flight mass spectrometry, and 64 metabolites were verified by standard library. There were some positive correlations between changes of typical metabolites and moxibustion product concentrations. The metabolites in the urine were most different between the high-dose moxibustion products group and normal control group. Twenty-two differential metabolites, such as glucuronic acid and vitamin C were mainly involved in 15 sugar and amino acid metabolic pathways, such as ascorbate and aldarate metabolism. These findings indicated that energy metabolism, detoxification and anoxidation increased in rats stimulated by moxibustion products.
