Objective The significance of serum cytokine profile in coronary heart disease patients have been evaluated by observing the variation cytokines Methods The serum IL-1 a,IL-1 ?,IL-2,IL-4, IL-6 ,IL-8,IL-10,VEGF,IFN-?,,TNF-?,MCP-1 and EGF in 76 patients and 26 matched healthy volunteers have been observed.Serum cytokines had been measured by protein chips methods in EVIDENCE 180 automatic biochips analyzer and cytokine profile were got by bioinformatics.Results The serum level of IL-1?,IL-6,IL-8,and TNF-? were (4.32?8.14) ng/L ,(13.16?16.81) rig/L,(375.53?292.14) ng/L,(15.46?15.38) ng/L respectively,which increased obviously in patients (P

This study was aimed to explore the relationship between changes of IL-4, IL-6 levels in blood plasma of patients receiving allo-HSCT and aGVHD through dynamical detection. The IL-4 and IL-6 levels in peripheral blood were detected by protein chip and were observed for 10 weeks. The results indicated that the IL-4 level increased rapidly in 1 week after transplantation in aGVHD group and was higher than that of non aGVHD group (p<0.05), while at 7th week after transplantation IL-4 level increased rapidly in non-GVHD group and was higher than that of aGVHD group (p<0.01). There was a significant difference of IL-6 level between these two groups before transplantation. IL-6 level reached peak at 1st week after transplantation in aGVHD group and was higher than that of non-aGVHD group (p<0.01), while IL-6 level was significantly higher in non-aGVHD group than that of aGVHD group at 4th week after transplantation (p<0.01) and at 5th week after transplantation (p<0.05). It is concluded that the levels of IL-4 and IL-6 had been increased rapidly after hematopoietic stem cell transplantation, indicating that aGVHD will occur. The high level of IL-6 before transplantation may be the risk factor of aGVHD occurrence after transplantation. aGVHD may occur later if the blood plasma IL-4 level rises in patients without aGVHD. Therefore, dynamically monitoring IL-4 and IL-6 levels contributes to predict the occurrence of aGVHD.

OBJECTIVETo study the effect of tanshinone II A on the cell signal transduction system protein kinase B (Akt) in rats with hypertrophy of the myocardium induced by partial constriction of the thoracic aorta.

METHODSRat models of myocardial hypertrophy were established by the thoracic aorta partial constriction method. Forty-eight rats were randomly divided into the sham-operative group, the model group, the valsartan treatment group, and the low-, medium-, and high-dose tanshinone treatment groups. The heart mass index (HMI), left ventricular mass index (LVMI), ejection fraction (EF), left ventricular posterior wall (LVPW), and interventricular septal thickness (IVS) were detected by high-frequency ultrasonography. The myocardial fiber diameter (MFD) was detected by HE staining, and the contents of p-Akt and p-Gsk3beta in the myocardium were detected by Western blot.

RESULTSCompared with the sham-operative group, the levels of HMI, LVMI, LVPW, IVS, and MFD were increased respectively in the other groups (P<0.05); the contents of p-Akt and p-Gsk3beta were also increased in the other groups. Compared with the model group, the levels of HMI, LVMI, LVPW, IVS, and MFD were decreased respectively in all treatment groups (P<0.05); the contents of p-Akt and p-Gsk3beta were decreased in all treatment groups as well. There was no significant difference, however, among the low-, medium-, and high-dose tanshinone treatment groups and the valsartan treatment group (P>0.05).

CONCLUSIONTanshinone II A can prevent myocardial hypertrophy by its action on the protein kinase B (Akt) signaling pathway.

OBJECTIVETo investigate the expression changes of metabotropic glutamate receptor 5 (mGluR5) in neuropathic pain.

METHODSEighty-four adult male Sprague Dawley rats weighing 180-220 g were randomly divided into 7 groups (n = 12) : control group; S3, S7, and S14 groups: rats received the sham operation, the mechanical pain threshold was measured, and then the rats were decapitated and the ipsilateral lumbar spinal cord dorsal horn and dorsal root ganglion (DRG) samples were obtained on the 3rd, 7th, 14th postoperative day, respectively; C3, C7, and C14 groups: the chronic sciatic nerve constriction (CCI) model was established, the mechanical pain threshold was measured and the samples were obtained on the 3rd, 7th, 14th postoperative day, respectively. The expression level of mGluR5 mRNA and protein in the spinal cord and DRG were measured using the reverse transcriptase polymerase chain reaction and Western blot.

RESULTSIn the CCI group, the mechanical pain threshold in each observation day was significantly lower than in the sham operation group (P < 0.05). In the spinal cord, the expressions of mGluR5 mRNA and protein were significantly elevated in the C3 group than in the S3 and the control group (P < 0.05). On the 7th and the 14th postoperative day, no significant difference was found in the expression of mGluR5 mRNA and protein between CCI groups and the sham operation groups or the control group. No change was detected in DRG mRNA or protein.

CONCLUSIONmGluR5 is differentially expressed in spinal cord in response to neuropathic pain, which suggests that mGluR5 may be involved in the mechanism of neuropathic pain.

OBJECTIVETo observe different effects of moxibustion on extracellular potassium ion in acupoint under physiological and pathological status and provide experimental evidence for exploring action mechanism of moxibustion on acupoint local.

METHODSForty female SD rats were randomly divided into a blank group, a blank-moxibustion group, a model group and a model-moxibustion group, 10 cases in each one. The complete Freund's adjuvant(CFA) was adopted to establish model of adjuvant arthritis (AA) in the model group and model-moxibustion group. No treatment was given in the blank group and model group while moxibustion was applied at "Zusan-li" (ST 36) for 30 min in the blank-moxibustion group and model-moxibustion group. The tissue fluid in "Zusanli" (ST 36) was collected with microdialysis and real-time analyzed by electrolytic analyzer. The change of concentration of potassium ion in "Zusanli" (ST 36) was observed.

RESULTS(1) Under physiological status, the concentration of extracellular potassium ion in the blank group was not changed within 150 min (P > 0.05); before the moxibustion, the concentration of extracellular potassium ion in the blank-moxibustion group was (1.21 +/- 0.31) mmol/L, and after treatment it was gradually increased and reached its peak at (2.38 +/- 0.42) mmol/L after 60 min (P < 0.05), then it was reduced. 150 min after the treatment, concentration of potassium ion was slightly higher than that before moxibustion as well as that in the blank group. The concentration in the blank-moxibustion group at 60 min was statistically significant compared with that in the blank group (P < 0.05). (2) Under pathological status, the concentration of extracellular potassium ion in the model group was not changed within 150 min, differences of which at each time point was not statistically significant (all P > 0.05). Before the moxibustion, the concentration of extracellular potassium ion was (1.09 +/- 0.12) mmol/L in the model-moxibustion group, and it was immediately increased to (1.96 +/- 0.18) mmol/L after moxibustion. 60 min and 90 min after the moxibustion, it still maintained a higher level, which was (1.87 +/- 0.29) mmol/L and (1.59 +/- 0.16) mmol/L respectively (both P < 0.05). The differences of each time point after moxibustion in the model-moxibustion group were statistically significant compared with those in the model group (all P < 0.05).

CONCLUSIONThe moxibustion could increase the concentration of potassium ion in rat's acupoint local under physiological status but time of effect is short; with moxibustion at "Zusanli" (ST 36) under pathological status, the concentration of local potassium ion is obviously increased and maintains for a long time.

BACKGROUNDThe treatment of high-grade developmental spondylolisthesis (HGDS) is still challenging and controversial. In this study, we investigated the efficacy of the posterior reduction and monosegmental fusion assisted by intraoperative three-dimensional (3D) navigation system in managing the HGDS.

METHODSThirteen consecutive HGDS patients were treated with posterior decompression, reduction and monosegmental fusion of L5/S1, assisted by intraoperative 3D navigation system. The clinical and radiographic outcomes were evaluated, with a minimum follow-up of 2 years. The differences between the pre- and post-operative measures were statistically analyzed using a two-tailed, paired t-test.

RESULTSAt most recent follow-up, 12 patients were pain-free. Only 1 patient had moderate pain. There were no permanent neurological complications or pseudarthrosis. The magnetic resonance imaging showed that there was no obvious disc degeneration in the adjacent segment. All radiographic parameters were improved. Mean slippage improved from 63.2% before surgery to 12.2% after surgery and 11.0% at latest follow-up. Lumbar lordosis changed from preoperative 34.9 ± 13.3° to postoperative 50.4 ± 9.9°, and 49.3 ± 7.8° at last follow-up. L5 incidence improved from 71.0 ± 11.3° to 54.0 ± 11.9° and did not change significantly at the last follow-up 53.1 ± 15.4°. While pelvic incidence remained unchanged, sacral slip significantly decreased from preoperative 32.7 ± 12.5° to postoperative 42.6 ± 9.8°and remained constant to the last follow-up 44.4 ± 6.9°. Pelvic tilt significantly decreased from 38.4 ± 12.5° to 30.9 ± 8.1° and remained unchanged at the last follow-up 28.1 ± 11.2°.

CONCLUSIONSPosterior reduction and monosegmental fusion of L5/S1 assisted by intraoperative 3D navigation are an effective technique for managing high-grade dysplastic spondylolisthesis. A complete reduction of local deformity and excellent correction of overall sagittal balance can be achieved.

OBJECTIVETo investigate the inhibitory effect and mechanism against the growth of human gastric carcinoma cell line HS-746T by the combination of the survivin antisense oligonucleotide (ASODN) and P53 gene and its mechanism.

METHODSGastric carcinoma cell line HS-746T was treated by P53 gene and survivin antisense oligonucleotide was designed. There were four regimen groups treated by different agents:ASODN alone, P53 gene alone and the combination of ASODN and P53 gene, blank control. Cell proliferative ability and cell growth were determined by cells counting and MTT. The expression of survivin mRNA and protein was detected by RT-PCR and Western blot respectively. Cell apoptotic index was detected by TUNEL.

RESULTSASODN alone, P53 alone and the combination of ASODN and P53 could inhibit not only the growth of gastric carcinoma cell, but also down-regulate the survivin mRNA and protein expression. The inhibitory effect was stronger, and the apoptosis index was higher in the combined transfection group than those in the other two single transfection groups.

CONCLUSIONThe combination of survivin ASODN and P53 gene is more efficient to inhibit cell growth and induce apoptosis than that of agent alone.

OBJECTIVETo study the effects of the extensive resection of the tumor-loading segment and artificial humerus head replacement combined with perioperative rehabilitation for the treatment of stage II to III giant cell tumor of bone in the proximal humerus.

METHODSFrom March 2007 to March 2010, 7 patients with stage II to III giant cell tumor of bone in the proximal humerus were treated. Among the patients, 3 patients were male and 4 patients were female with a mean age of 34.6 years (ranged, 18 to 49 years). The mean course of disease was 19 months (ranged, 6 to 35 months). All the patients were confirmed to suffer stage II to III giant cell tumor of bone in the proximal humerus by pathology and X-ray examinations. Clinical manifestations of the patients included persistence aggravated pain of the shoulder, swelling in the proximate arm with obviously tenderness, activity limited of the joint. All the patients were treated with extensive resection of the tumor-loading segment and artificial humerus head replacement combined with perioperative rehabilitation. CMS and OSIS score system were used to evaluate shoulder function and shoulder stability.

RESULTSAll the patients were followed up, and the duration ranged from 14 to 35 months, with an average of 17 months. There were no serious complications or recurrence in all cases. One year after the surgery CMS and OSIS score system were 70.7 scores (ranged,63 to 82 scores) and 25.1 scores (ranged, 18 to 29 scores) respectively. According to evaluation for shoulder function, 2 patients got an excellent result and 5 good. According to evaluation of shoulder stability, 1 patient got an excellent result and 6 good.

CONCLUSIONExtensive resection of the tumor-loading segment and artificial humerus head replacement combined with perioperative rehabilitation for the treatment of stage II to III giant cell tumor of bone in the proximal humerus would not only preserve the upper extremity but also preserve the function of upper extremity.

BACKGROUNDThe rodentia and lagomorpha animals are the intermediate hosts of Echinococcus multilocularis, their distribution and infection of this parasite may facilitate the infection of definitive hosts such as dogs. The aim of this study was to determine the distribution of the intermediate hosts of Echinococcus multilocularis in Shiqu County, Sichuan, China.

METHODSA systematic sampling method was used to investigate the density of burrows of rodents and lagomorphs at 97 pasture sites in winter and summer pastureland and remote sensing (RS) technology was used to correlate their densities to the distribution of these animals in different landscape types.

RESULTSBased on the densities of Ochotona curzoniae, Microtus fuscus (dependent variable) and their burrow densities (independent variable) in survey points, regression equations were fitted respectively (Ochotona curzoniae, P < 0.0001, R(2) = 0.8705; Microtus fuscus, P < 0.0001, R(2) = 0.9736). Their burrow density in summer pastureland was higher than in winter pastureland (F = 36.65, P < 0.0001). The burrow densities of Ochotona curzoniae and Microtus fuscus in bareland and half-bareland are higher than in grassland (F = 7.73, P < 0.001).

CONCLUSIONSThe regression relationship between the densities of Ochotona curzoniae and Microtus fuscus and their burrow densities indicate that the burrow densities could reflect the animal densities and that the burrow density was greater in summer pastureland than in winter pastureland. The main distribution areas of the intermediate hosts were in bareland and half-bareland.
