OBJECTIVE:To investigate effectiveness and safety of rh-endostatin in the treatment of keloid.METHODS:Sixty-four keloid patients in Nanchong Central Hospital during Jan.2015-Jan:2016 were divided into observation group and control group by random number table,with 32 cases in each group.Both group received fractional CO2 laser treatment.After surgery,control group was given antioxidant drug and antibiotics routinely.Observation group was additionally given Rh-endostatin injection 0.1-0.2 mg/cm2 via keloid body,once a month,for twice,on the basis of control group.Clinical efficacy,symptom score after laser treatment and 2 months after laser treatment,wound healing time,wound pigmentation area and keloid area before and after treatment,the occurrence of ADR were compared between 2 groups.RESULTS:There was no statistical significance in total re sponse rate (93.75％ vs.87.50％) and the incidence of ADR (15.63％ vs.12.50％) between observation group and control group (P＞0.05).There was no statistical significance in symptom score of control group between after laser treatment and after 2 months of treatment (P＞0.05).The erythema,edema and pigmentation scores of observation group were significantly lower than before treatment and control group,with statistical significance (P＜0.05);there was no statistical significance in skin itching and burning sensation score between 2 groups (P＞0.05).The wound incrustation time,decrustation time and wound healing time of observation group were significantly shorter than those of control group,with statistical significance (P＜0.05).Pigmentation area and keloid area of 2 groups were significantly smaller than before,and the observation group was significantly smaller than the control group,with statistical significance (P＜0.05).CONCLUSIONS:Rh-endostatin can alleviate erythema,edema,pigmenta tion and other symptoms effectively,shorten healing time,and inhibit pigmentation and keloid regeneration effectively with good safety.

ObjectiveTo detect the effect of electroacupuncture combined with acupoint injection of deer melon polypeptide on the bone morpho-genetic protein synovial, BMPs and serum rheumatoid factor IgA-RF, IgM-RF.MethodsA total of 246 patients with Rheumatoid arthritis were divided randomly into control group and combined treatment group, 123 patients in each group. The control group received the treatment of electro-acupuncture, drug and Ultrashort wave therapy, and the combined treatment group continue to receive acupoint injection of deer melon polypeptide after 30 minutes when the treatment of control group was completed. Both groups were treated for 2 weeks. The expression of BMPs, MMP-1 and the ESR, serum rheumatoid factor IgA-RF, IgM-RF were detected. The morning stiffness time, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and visual analogue scale (VAS) were recorded for outcome assessment.ResultsCompared with control group after treatment, the positive expression rates of ESR (8.79 ±1.61 mm/hvs.12.41 ± 2.57 mm/h,t=3.654), IgM-RF (22.38% ± 5.45%vs.39.57% ± 6.18%,t=2.365), IgA RF (32.84% ± 6.57%vs.49.84% ± 4.20%,t=2.574) in the combined treatment group significantly decreased. Compared with the control group, the expression of BMPs (15.43 ± 2.94vs.7.22 ± 1.52,t=3.914) in the combined treatment group significantly increased, while MMP-1 (8.01% ± 1.54%vs. 15.34% ± 2.47%,t=2.015) in the combined treatment group significantly decreased (P<0.05). Compared with control group, the outcomes VAS (3.37 ± 0.35 vs.5.75 ± 0.39, t=3.251), WOMAC (22.36 ± 3.49vs.30.50 ± 4.11,t=4.021), and morning stiffness (34.32 ± 5.57 minvs. 49.84 ± 4.20 min,t=3.914) in the combined treatment group significantly decreased (P<0.05). The total effect rate (82.11%vs. 71.55%,χ2=12.764) of combined treatment group was significantly higher than control group (P<0.05).Conclusion Electroacupuncture combined with acupoint injection of deer and melon peptide can improve effect rate.

Aim To investigate whether rosuvastatin induced reduction of atherosclerotic plaque was related to the expression of Sialyltransferase ( ST6 Gal-Ⅰ) in ApoE-/ - mice. Methods Six-weeks old ApoE-/ -mice fed with high fat were divided randomly into three groups: baseline group ( n=12 ) , control group ( n=12 ) and rosuvastatin group ( n =12 ) . Sixteen weeks later, control group was sacrificed. Serum and aortic intima were saved. Control group and rosuvastatin group were fed for seven weeks continually. Concentra-tions of serum lipids(TC, TG, LDL and HDL) were analyzed. Sections from the aortic root were examined by Hematoxylin-Eosin( HE) staining. The size of ath-erosclerotic lesion in each section was evaluated. Ex-pression of ST6 Gal-Ⅰ in aortic intima was detected by immunohistochemistry. Results Plasma TG and LDL-C, plaque areas and intimal thickness of control group were significant higher than those of baseline group ( P<0. 05 ) . Those results indicated that the AS model was successfully constructed. After seven weeks, the plaque areas and concentrations of serum lipids of rosu-vastatin group were obviously smaller than those of con-trol group(P<0. 05). The expression of ST6Gal-Ⅰin aortic root was decreased in control group compared to the baseline, and which was increased in control group compared to the rosuvastatin group. Conclusion Ro-suvastatin could inhibit the progression of atherosclero-sis, which might be related to the expression of ST6Gal-Ⅰ in aortic root.

Objective To investigate the effects of oxidative stress on homocysteine and related amino acids metabolism in methionine-loading BRL rat hepatocytes.Methods Cultured BRL rat hepatocytes were divided into control and oxidatively stressed group(100 μmol/L H2O2 was added in culture medium for 2 hours),methionine group(50 mmol/L methionine was added in culture medium for 1 hour),and oxidatively stressed + methionine group(100 μmol/L H2O2 was added in culture medium for 2 hours + 50 mmol/L methionine was added in culture medium for 1 hour).At the end of the experiment,culture fluid was collected.Homocysteine,cysteine,and glutathione were measured by high-performance liquid chromatography,and amino acids were assayed by amino acids analyzer.Results Compared with the control group,the contents of homocysteine[(3.76 ± 0.22)vs.(1.54±0.05)μmol/L,P=0.000]and cysteine[(199.80 ±8.75)vs.(99.11 ±2.47)μmol/L,P=0.000]significantly increased in methionine group,and the contents of homocysteine[(3.84 ± 0.34)vs.(1.54 ±0.05)μmol/L,P=0.000]and cysteine[(200.66±8.60)vs.(99.11 ±2.47)μ mol/L,P=0.000]also increased in oxidatively stressed + methionine group.Compared with oxidatively stressed group,the concentrations of homocysteine[(3.76 ± 0.22)vs.(1.67 ± 0.13)μmol/L,P =0.000],cysteine[(199.80 ± 8.75)vs.(82.64±15.88)μmol/L,P=0.000],and glutathione[(1.50 ±0.14)vs.(1.00 ±0.11)μ mol/L,P=0.011)]significantly increased in methionine group,and the concentrations of homocysteine[(3.84 ± 0.34)vs.(1.67±0.13)μmol/L,P=0.000],cysteine[(200.66±8.60)vs.(82.64±15.88)μmol/L,P=0.000]and glutathione[(1.40 ± 0.30)vs.(1.00 ± 0.11)μmol/L,P =0.028]significantly increased in oxidatively stressed + methionine groups.Compared with the control group,the contents of serine[(12.41 ± 1.51)vs.(24.00 ±2.54)mg/L,P =0.000],glutamate[(33.31 ±0.17)vs.(43.10 ±0.52)mg/L,P =0.000]and glycine[(6.23 ± 0.18)vs.(24.66 ± 10.87)mg/L,P =0.000]significantly decreased,while taurine [(7.99 ±0.16)vs.(6.17 ±0.15)mg/L,P =0.000]increased significantly in oxidatively stressed group.Compared with the oxidatively stressed group,the concentrations of serine[(16.98 ± 0.39)vs.(12.41 ± 1.51)mg/L,P=0.006)]and glutamate[(35.44 ±0.82)vs.(33.31 ±0.17)mg/L,P =0.002]in methionine group significantly increased,while taurine[(3.77 ±0.16)vs.(7.99 ±0.16)mg/L,P =0.000]significantly decreased in methionine group.Compared with the methionine group,the contents of serine[(12.59 ± 0.66)vs.(16.98±0.39)mg/L,P=0.008],glutamate[(30.87±0.60)vs.(35.44±0.82)mg/L,P=0.000]significantly decreased while taurine[(4.37 ± 0.12)vs.(3.77 ± 0.16)mg/L,P =0.001]in oxidatively stressed + methionine group significantly increased.Conclusion Oxidative stress can somehow promote homocysteine production in methionine loading BRL rat hepatocytes,but it is not the main effects.

A novel suspension array technology was established for the detection of three kinds of veterinary drug residues: chloramphenicol, clenbuterol and 17-β-estradiol. The three conjugates in which veterinary drugs coupled with BSA were immobilized on the solid carrier of the suspension microarray-polystyrene fluorescent microspheres/beads as detective probes. Indirect competitive technology was employed. Competitive reactions between the veterinary drugs in the aqueous phase and the veterinary drugs-BSA conjugates on the beads for coupling with their complimentary specific biotinylated monoclonal antibodies were carried out. And then, straptavidin-phycoerythrin was added for coupling and the fluorescent signals were captured. Afterwards the detective standard curves were plotted. The regular ELISA standard curves of the three veterinary drugs were also plotted. Comparison between suspension array and regular enzymE-linked immunosorbent assay(ELISA) was in the respects of the detective technology, the detection limits, the detective ranges, the samples detection and the multi-analysis. Suspension array technology is distinct advantageous except for specificity. There was well consistent performance between the two methods. The high-throughput suspension array provides a novel method for multi-analysis of veterinary drugs with simple operation, sensitive, rapid and low costing.

OBJECTIVETo explore and compare the clinical effects of three immuno-potentiators and their influence on immune function in preventing and treating recurrent respiratory tract infection (RRI).

METHODSSeventy-two children with RRT were assigned to three groups, the 23 patients in the M group treated with milkvetch extract oral liquid, the 23 in the P group treated by P-transfer factor and the 26 in the U group treated by Utilins injection. Clinical effect was compared among three groups after treatment, and changes of T cell subgroups as well as immune antibodies were detected before and after treatment.

RESULTSThe markedly effective rate in the M, P, and U group was 69.6%, 65.2%, and 73.0% respectively, and the total effective rate 87.0%, 82.6%, and 92.3%, showing an insignificant difference among them (all P>0.05). After treatment, the levels of CD3+, CD4+ and CD4+/CD8+ rose obviously in the three groups (all P<0.05); levels of CD8+ in the M group and the P group lowered significantly (P<0.05, P<0.01), but with no significant difference among three groups in the changes of T cell subgroups (all P>0.05). Serum levels of IgG in all the three groups, IgA in the P group and the M group, and IgM in the M group and the U group rose significantly (P<0.05 or P<0.01), with statistical difference presented in comparing of IgA level in the P group with that in the other two groups (P<0.01).

CONCLUSIONThe clinical effects and the outcomes of immunological indexes' changing are similar in RRI patients treated by the three immuno-potentiators. They all can enhance the immunological function of the organism, strengthen the disease-resistant ability of patients, and reduce the incidence of RRI. Among them, the milkvetch extract oral liquid is worthy of spreading due to its lower cost, simple administration, exemption from painful injection, and good compliance.

OBJECTIVETo investigate the effects of Salvia miltiorrhiza (SM) on oxidative stress and microinflammatory state in patients undergoing continuous hemodialysis (CHD).

METHODSThirty-six patients who had received CHD for over half a year were assigned into the routine CHD group (18 cases) and the treated group treated with routine CHD plus SM (18 cases). Meanwhile, 18 healthy adults were taken as the normal control. Indexes related with oxidative stress [malondialdehyde (MDA), advanced oxidative protein products (AOPP) and superoxide dismutase (SOD)) and microinflammation C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) were detected before and after 1, 2 and 3 months of treatment.

RESULTSThe levels of AOPP, MDA, CRP, IL-6 and TNF-alpha in patients were higher and SOD was lower than those in the normal control at all the time points (P < 0.01). Compared with the baseline, the levels of AOPP and MDA in the routine CHD group significantly increased and SOD decreased after 3 months of treatment (P < 0.05), but changes of CRP, IL-6 and TNF-alpha showed no significance though there were somewhat increment (P > 0.05). The levels of AOPP and MDA were lower and SOD was higher after 1, 2 and 3 months of SM combined treatment, and CRP was lower after 3 months of treatment in the treated group than those of baselines and those at the corresponding time points in the routine CHD group (P < 0.01), but IL-6 and TNF-alpha reduced insignificantly (P > 0.05).

CONCLUSIONHemodialysis may aggravate the oxidative stress and microinflammation in patients, which could be obviously alleviated by SM.
