Objective To investigate the relationship between negative acute phase proteins and chronic urticaria (CU).Methods Fifty patients with CU were enrolled into this study,and divided into three grades,i.e.,mild (grade 1),moderate (grade 2) and severe (grade 3) according to symptoms.Twenty-eight health checkup examinees served as the control group.Immunoturbidimetry was performed to determine serum levels of prealbumin (PA) and transferrin (TRF).Enzyme-linked immunosorbent assay was conducted to measure serum levels of insulinlike growth factor-1 (IGF-1) and tumor necrosis factor-α (TNF-α).Statistical analysis was carried out to assess differences in these indices between these two groups,the relationship among these indices and between these indices and disease severity.Results Compared with the control group,the patients with CU showed reduced serum levels of PA ((229.99 ± 54.16) vs.(272.06 ± 36.42) mg/L,t =3.667,P ＜ 0.05) and IGF-1 ((177.23 ± 46.48) vs.(239.88 ± 45.16) μg/L,t =5.748,P＜ 0.05),but higher serum levels of TNF-α ((25.39 ± 11.01) vs.(14.13 ± 6.12) ng/L,t =4.989,P＜ 0.05),and similar serum levels of TRF ((2.48 ± 0.49) vs.(2.48 ± 0.25) g/L,P＞ 0.05).The serum level of PA showed a significant negative correlation with that of TNF-α (r =-0.312,P ＜ 0.05),as well as with disease severity (r =-0.635,P ＜ 0.01),whereas the serum level of TNF-α showed a significant positive correlation with disease severity (r =0.409,P ＜ 0.01),and no statistical correlation was found between the remaining indices (all P ＞ 0.05) in the patients with CU.Conclusions Serum levels of some negative acute phase proteins decrease and negatively correlate with disease severity in patients with CU.Acute phase response may be involved in the occurrence of CU.

Objective To evaluate the relationship of acute-phase response and coagulation/fibrinolysis with chronic urticaria (CU).Methods Fifty-three patients with CU and twenty-five healthy human controls were enrolled in this study.Venous blood samples were collected from all of these subjects.Then,enzyme-linked immunosorbent assay was carried out to measure the serum levels of interleukin-6 (IL-6) and amyloid protein A (AA),and immunoturbidimetry to determine the levels of serum high sensitive C-reactive protein (Hs-CRP) and plasma D-dimer.The patients with CU were classified into three groups according to the severity of clinical symptoms.The levels of serum IL-6 and plasma D-dimer were given in mean ± standard deviation,and those of serum AA and Hs-CRP in mean (25th percentile,75th percentile).Rank sum test and t test were performed to compare these parameters between the patients and controls,and Spearman rank correlation analysis was conducted to study the relationship among these parameters as well as between these parameters and symptom severity in these patients.Results The levels of serum IL-6,serum AA and plasma D-dimer were (10.70 ± 4.94) ng/L,4.92 (8.22,12.51) μg/L,and (222.32 ± 163.69) μg/L respectively in the patients with CU,significantly higher than those in the healthy controls ((7.49 ± 3.41) ng/L,2.11 (1.21,2.83) μg/L,(104.72 ± 43.12) μg/L,respectively,all P＜ 0.05),while no significant differences were observed between the patients and controls in the level of serum HsCRP (0.30 (0.10,1.40) mg/L vs.0.30 (0.10,0.55) mg/L,P ＞ 0.05).In patients with CU,the levels of serum IL-6 were unrelated to those of serum Hs-CRP,serum AA,or plasma D-dimer (all P ＞ 0.05),whereas a positive correlation was observed between the levels of serum Hs-CRP and AA (r =0.67,P ＜ 0.01),serum Hs-CRP and plasma D-dimer (r =0.49,P ＜ 0.01),serum AA and plasma D-dimer (r =0.38,P ＜ 0.01).Further more,the levels of serum Hs-CRP,AA and plasma D-dimer were significantly correlated with symptom severity in patients with CU (r =0.63,0.62,0.47,respectively,all P ＜ 0.01).Conclusions Acute-phase response coexists with the activation of coagulation system in patients with CU,suggesting a potential association between acute-phase response and coagulation system activation.

Objective To compare recent curative effect between double Endobutton technique and clavicular hook plate (CHP) in patients with Tossy grade Ⅲ acromioclavicular separation.Methods One hundred and forty-nine patients with Tossy grade Ⅲ acromioclavicular dislocation were divided into control group (78 cases,treated with CHP) and observation group (71 cases,treated with double Endobutton technique) according to treatment method.The postoperative injured shoulder visual analogue score (VAS),abduction-rise activity and flexion-rise activity,Constant-Murley score and Karlsson grade were compared between 2 groups.Results All the patients successfully completed the operation,and the postoperative follow-up time was 9-40 (15.8 ± 5.2) months.The injured shoulder abduction-rise activity and flexion-rise activity postoperative 9 months in observation group were (100.9 ± 13.3)° and (131.6 ± 13.4)°,in control group were (81.4 ± 8.4)° and (96.7 ± 10.9)°; the injured shoulder VAS in observation group and control group were (2.2-± 0.8) and (3.0 ± 0.9) scores,and there were statistical differences between 2 groups (P ＜ 0.01).The Constant-Murley score in observation group and control group were (85.4 ± 6.4) and (82.5 ± 6.2) scores,the excellent and good rate of Karlsson grade in observation group and control group were 84.5％(60/71),91.0％ (71/78),and there were no statistical differences (P ＞ 0.05).Conclusions The recent curative effect of double Endobutton technique and CHP in patients with Tossy grade Ⅲ acromioclavicular separation is similar.

We performed a meta-analysis of randomized controlled trials (RCTs) to investigate the efficacy and safety of ticagrelor (TIC) vs.clopidogrel (CLO) in patients undergoing percutaneous coronary intervention (PCI).In Jun 2016,a literature search was started and all the studies were conducted from 2010 to 2015.We systematically searched the literature through the MEDLINE database,Cochrane library,and EMBASE database.Quality assessments were evaluated with Jadad quality scale.Data were extracted considering the characteristics of efficacy and safety designs.Six RCTs enrolling 26 244 participants and satisfying the inclusion criteria were finally analyzed.There was a significant decrease of all-cause mortality (MD=0.83,95％CI=0.74-0.93,P=0.001) and myocardial infarction (MI) (MD=0.78,95％CI=0.70~.88,P=0.000).There were no significant differences in stroke (MD=1.34,95％CI=0.99-1.79,P=0.06),total bleeding (MD=0.97,95％CI=0.84-1.12,P=0.66),minor or major bleeding (MD=l.06,95％CI=0.94-1.19,P=0.35) in patients undergoing PCI after treatment with TIC vs.CLO.TIC could be more significant in decreasing all-cause mortality and MI than CLO,but there were no significant differences between TIC and CLO in inhibiting stroke,major bleeding,major or minor bleeding in patients undergoing PCI.

BACKGROUND:Despite tissue repair with a kind of stem cels has achieved great outcomes, but the combination of two or more kinds of stem cels to construct tissue-engineered bone is stil rare.
OBJECTIVE:To evaluate the efficacy of tissue-engineered bone constructed based on combining adipose-derived stem cels with bone marrow mesenchymal stem cels and alogenic bone in rabbit posterior intertransverse lumbar interbody fusion models.
METHODS:Seventy-five New Zealand rabbits were randomly divided into five groups. L5,6 interbody fusion models were made in each group. Then, these five groups were respectively treated as folows (1) group A: bone marrow mesenchymal stem cels/alograft iliac bone with adipose-derived stem cels; (2) group B: bone marrow mesenchymal stem cels/alograft iliac bone with normal saline; (3) group C: alograft iliac bone with adipose-derived stem cels; (4) group D: alograft iliac bone with normal saline; group E: autologous iliac bone alone. Each group was detected by PET/CT to contrast the standard uptake value at 1, 3, 5 weeks postoperatively.
RESULTS AND CONCLUSION: PET/CT images showed varying degrees of bone fusion and bone metabolism enhancement in the five groups. With time, the standard uptake value was increased in each group, and except the group D, the standard uptake value was higher in al the groups at 3, 5 weeks than at 1 week (P < 0.05). There was no difference in the standard uptake value of al the five groups at weeks 3 and 5 after operation (P > 0.05). The standard uptake value of the group A was better than that in the group B and group E (P < 0.05). Taken together, the combination of adipose-derived stem cels and bone marrow mesenchymal stem cels for rapid production of tissue-engineered bone has good osteogenesis and vascularization.

OBJECTIVETo determine the equilibrium solubility of pulchinenosiden D in different solvents and its n-octanol/water partition coefficients.

METHODCombining shaking flask method and high performance liquid chromatography (HPLC) to detect the n-octanol/water partition coefficients of pulchinenosiden D, the equilibrium solubility of pulchinenosiden D in six organic solvents and different pH buffer solution were determined by HPLC analysis.

RESULTn-Octanol/water partition coefficients of pulchinenosiden D in different pH were greater than zero, the equilibrium solubility of pulchinenosiden D was increased with increase the pH of the buffer solution. The maximum equilibrium solubility of pulchinenosiden D was 255.89 g x L(-1) in methanol, and minimum equilibrium solubility of pulchinenosiden D was 0.20 g x L(-1) in acetonitrile.

CONCLUSIONUnder gastrointestinal physiological conditions, pulchinenosiden D exists in molecular state and it has good absorption but poor water-solubility, so increasing the dissolution rate of pulchinenosiden D may enhance its bioavailability.

OBJECTIVETo study the effects of Jisuikang (Chinese characters) on Nogo-NgR gene expression, and to explore the protective effects and mechanism of Jisuikang (Chinese characters) on spinal cord injury in rats.

METHODSOne hundred eighty female rats were randomly assigned to 6 groups(30 rats per group). Sham group: T10 lamina was resected only and spinal cord was untreated. Model group: spine cord injury (SCI) was created with a modified impinger of Allen's by impacting on the T10 spinal cord. Prednisolone group: Prednisolone (0.06 g/kg) was given by intragastric administration at a time interval of 24 hours after operation. The Jisuikang (Chinese characters) high, moderate and low dose groups: Jisuikang (Chinese characters) was supplied with different dose (50 g/kg, 25 g/kg, 12.5 g/kg) by intragastric administration in rats after operation,for the first time at 30 min after surgery. Animals were killed 3, 7, 14 days after surgery. The expression levels of Nogo-A and NgR were observed by Western Blot and Real-time PCR.

RESULTSThe expression of Nogo-A and NgR was at the basic level at all time points in sham group. Compared with model group, the protein expression levels of Nogo-A and NgR in sham, prednisolone, Jisuikang (Chinese characters) moderate dose groups were statistically significant at all time points (P < 0.05). No difference was found in Jisuikang (Chinese characters) high and low dose groups (P > 0.05). Three days after surgery, the mRNA levels of Nogo-A and NgR in treatment group were significantly lower than that in model group (P < 0.01); 7 days after surgery,Nogo-A and NgR mRNA expression were dramatically upregulated and peaked; 14 days after operation, the expression was decreased, but still significantly higher than that in other treatment groups (P < 0.01). Prednisolone and Jisuikang (Chinese characters) moderate dose groups showed the most significant effects among all groups,but there was no statistically significant difference between two groups (P > 0.05).

CONCLUSIONThe decoction Jisuikang (Chinese characters) can promote the nerve cell regeneration by regulating Nogo-A and NgR gene expression, activating Nogo- NgR signaling pathways after acute spinal cord injury.
