Objective: To observe the effect of electroacupuncture (EA) pretreatment on the protein expression of c-fos in fastigial nucleus (FN) and lateral hypothalamus area (LHA) in rats with acute myocardial ischemia-reperfusion injury (MIRI), and to explore the role and mechanism of FN and LHA in EA at the Heart Meridian fighting against acute MIRI reaction. Methods: Seventy Sprague-Dawley rats were randomly divided into a sham operation group, a model group, an EA-Heart Meridian group and an EA-Lung Meridian group, with 14 rats in each group; an LHA lesion plus EA-Heart Meridian group (LHA+EA-Heart Meridian group) and a FN lesion plus EA-Heart Meridian group (FN+EA-Heart Meridian group), with 7 rats in each group. Except the sham operation group, the left anterior descending branch of coronary artery was ligated to establish acute MIRI rat models in the other 5 groups. In the three groups with EA-Heart Meridian treatment, Shenmen (HT 7) and Tongli (HT 5) were selected; Taiyuan (LU 9) and Lieque (LU 7) were selected in the EA-Lung Meridian group. All the EA groups received EA stimulation prior to modeling, with 1 mA in current intensity and 2 Hz in frequency, 20 min each time, once a day for a total of 7 d. The sham operation group and the model group did not receive EA stimulation. The electrocardiogram was observed in the rats to analyze the ST-segment deviation and cardiac arrhythmia score. The expression of c-fos protein in FN and LHA was detected by immunohistochemistry method. Results: Compared with the sham operation group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in the FN and LHA increased significantly in the model group (all P<0.05). Compared with the model group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in FN and LHA decreased significantly in the EA-Heart Meridian group (all P<0.05). Compared with the EA-Heart Meridian group, the ST-segment deviation and cardiac arrhythmia score increased significantly in the EA-Lung Meridian group, LHA+EA-Heart Meridian group and FN+EA-Heart Meridian group (all P<0.05); the expression of c-fos in FN increased significantly in the EA-Lung Meridian group and LHA+EA-Heart Meridian group (both P<0.05); the expression of c-fos in LHA increased significantly in the EA-Lung Meridian group and FN+EA-Heart Meridian group (both P<0.05). Conclusion: FN and LHA are involved in the mechanism of EA at Heart Meridian to improve the acute MIRI reactions, and the cerebellum may participate in the improvement of cardiac function by EA through the cerebellum-hypothalamus projection.

To observe a PPAR-alpha agonist effect of N-oleoylethanolamine (OEA) on CB2 (cannabinoid receptor 2), an anti-inflammatory receptor in vascular endothelial cell, healthy HUVECs and TNF-alpha induced HUVECs were used to establish a human vascular endothelial cell inflammatory model. Different doses of OEA (10, 50 and 100 micromol x L(-1)) had been given to HUVECs, cultured at 37 degrees C for 7 h and then collected the total protein and total mRNA. CB2 protein expression was detected by Western blotting and CB2 mRNA expression was assayed by real-time PCR. As the results shown, OEA (10 and 50 micromol x L(-1)) could induce the CB2 protein and mRNA expression, but not 100 micromol x L(-1). To detect if anti-inflammation effect of OEA is partly through CB2, CB2 inhibitor AM630 was used to inhibit HUVEC CB2 expression, then the VCAM-1 expression induced by TNF-alpha was detected, or THP-1 adhere to TNF-alpha induced HUVECs was examined. OEA (50 micromol x L(-1)) could inhibit TNF-alpha induced VCAM-1 expression and THP-1 adhere to HUVECs, these effects could be partly inhibited by a CB2 inhibitor AM630. The anti-inflammation effect of OEA is induced by PPAR-alpha and CB2, suggesting that CB2 signaling could be a target for anti-atherosclerosis, OEA have wide effect in anti-inflammation, it may have better therapeutic potential in anti-inflammation in HUVECs, thus achieving anti-atherosclerosis effect.

·AIM:To determine the effect of anterior-posterior joint surgery on choroidal thickness in patients with proliferative diabetic retinopathy (PDR). · METHODS: A retrospective, case - control study enrolled 60 eyes of 60 patients with PDR diagnosed at Qingdao Municipal Hospital. The patients, who had conditions that warranted anterior - posterior joint surgery,were divided into a clinically significant macular edema group (PDR/CSME+;31 patients,31 eyes) and a non-CSME group (PDR/CSME-;29 patients,29 eyes). Twenty-seven eyes of 27 normal patients were included in the control group. All affected eyes underwent anterior - posterior joint surgery. After surgery, the subfoveal choroidal thickness (SFCT), and the nasal choroidal thickness (NCT) and temporal choroidal thickness (TCT), which were obtained at a distance of 1500μ m from the fovea in the nasal and temporal directions, respectively, were measured in the control and PDR groups by enhanced depth imaging spectral domain optical coherence tomography (EDI-SDOCT) at 1wk,1,3, and 6mo after surgery. Changes in choroidal thickness after anterior - posterior joint surgery were compared between the groups. ·RESULTS:The SFCT,NCT,and TCT were significantly thicker at 1mo than at 1wk, 3, and 6mo after surgery in the PDR/CSME+ and PDR/CSME- groups(P<0.05). The SFCT, NCT, and TCT were significantly thinner at 6mo than at 1wk,1,and 3mo after surgery in the PDR/CSME+and PDR/CSME- groups(P<0.05). The SFCT,NCT,and TCT in the PDR/CSME+ and PDR/CSME- groups at 1wk, 1, and 3mo after surgery were significantly thicker than those in the control group (all P<0.05), but the SFCT, NCT, and TCT at 6mo after surgery showed no significant difference compared with the control group (all P>0.05). There was no significant difference in the SFCT,NCT, or TCT at 1wk, 1, 3, or 6mo between the PDR/CSME+ and PDR/CSME- groups (P>0.05). ·CONCLUSION:The choroidal thickness of PDR patients increases within 1mo after surgery, and decreased after 1mo,but is not significantly different between the control group and the PDR groups at 6mo after surgery. Whether PDR is associated with CSME has no effect on the choroidal thickness after surgery.

Increasing evidence has revealed that maternal cytomegalovirus (CMV) infection may be associated with neurodevelopmental disorders in offspring.Potential relevance between the placental inflammation and CMV-related autism has been reported by clinical observation.Meanwhile,abnormal expression of Toll-like receptor 2 (TLR2) and TLR4 in placenta of patients with chorioamnionitis was observed in multiple studies.IL-6 and IL-10 are two important maternal inflammatory mediators involved in neurodevelopmental disorders.To investigate whether murine CMV (MCMV) infection causes alterations in placental IL-6/10 and TLR2/4 levels,we analyzed the dynamic changes in gene expression of TLR2/4 and IL-6/10 in placentas following acute MCMV infection.Mouse model of acute MCMV infection during pregnancy was created,and pre-pregnant MCMV infected,lipopolysaccharide (LPS)-treated and uninfected mice were used as controls.At E13.5,E14.5 and E18.5,placentas and fetal brains were harvested and mRNA expression levels of placental TLR2/4 and IL-6/10 were analyzed.The results showed that after acute MCMV infection,the expression levels of placental TLR2/4 and IL-6 were elevated at E13.5,accompanied by obvious placental inflammation and reduction of placenta and fetal brain weights.However,LPS 50 μg/kg could decrease the IL-6 expression at E13.5 and E14.5.This suggests that acute MCMV infection during pregnancy could up-regulate the gene expression of TLR2/4 in placental trophoblasts and activate them to produce more proinflammatory cytokine IL-6.High dose of LPS stimulation (50 tg/kg) during pregnancy can lead to down-regulation of IL-6 levels in the late stage.Imbalance ofIL-6 expression in placenta might be associated with the neurodevelopmental disorders in progeny.

OBJECTIVETo study the relationship of the incidence of bronchial dysplasia (bronchial anomalous origin and bronchial stenosis) with congenital heart disease.
METHODSA total of 185 children with congenital heart disease or bronchial dysplasia were enrolled. Bronchial dysplasia was identified by the 64-MSCT conventional scanning or thin slice scanning with three-dimensional reconstruction.
RESULTSForty-five children (25.3%) had coexisting bronchial dysplasia and congenital heart disease. The incidence rate of bronchial dysplasia in children with congenital heart disease associated with ventricular septal defect was higher than in those without ventricular septal defect (33.7% vs 15.0%; P<0.05). There were no significant differences in the incidence rate of bronchial dysplasia between the children with congenital heart disease who had a large vascular malformation and who did not.
CONCLUSIONSBronchial dysplasia often occurs in children with congenital heart disease. It is necessary to perform a tracheobronchial CT scanning with three-dimensional reconstruction to identify tracheobronchial dysplasia in children with congenital heart disease, especially associated with ventricular septal defect.

OBJECTIVETo analyze the radiological parameters of the conservatively in treating distal radius fracture and investigate whether the final re-displacement can be predicted after primary reduction.
METHODSFrom January 2013 to June 2014,212 patients with distal radial fracture conservatively were treated in our hospital, 107 patients of them were excluded because of their incomplete radiological parameters;the remaining 105 patients were available for radiological were assessed after injury, there were 56 male patients and 49 female patients in this study, the average age of the patients was 51 years old (ranged from 22 to 80 years). According to AO classification, there were 47 cases of type A2 and C1, and 58 cases of type A3, C2, C3. All patients were treated by closed reduction and below-elbow cast immobilization for 4 to 6 weeks. All patients were followed up for 3 to 6 months (means 4.5 months) by X-ray, all fractures were healed. Standard AP and lateral radiographic examination was conducted before reduction and after reduction and bony consolidation,the dorsal angulation and the radial angle were measured at each time point. The linear regression was used for the analysis to find out whether the final re-displacement can be predicted after primary reduction.
RESULTSAmong 105 patients,the significant correlations were found for the dorsal angulation between the reduction time and the end time (r = 0.82) and for the radial angulation between the reduction time and end time (r = 0.85).
CONCLUSIONThe dorsal angulation and the radial angulation after complete healing can be predicted from linear the regression functions. Due to the possibility of predicting the end result, whether the fracture should receive further conservative treatment or surgical treatment can be decided immediately.

OBJECTIVETo analyze the level of mortality of brain tumor and its changes at different periods in China.
METHODSDeath records for tumor of brain and central nervous system, which the code of international classification of diseases-10 (ICD-10) were C70-C72, were extracted from the database of the Third National Retrospective Sampling Survey of Death Causes in China during 2004 to 2005. The corresponding population data was linked to the data of death records, that the total population was 142 660 482 person years (72 970 241 person years in male, 69 690 241 person years in female). Then crude death rate, age-specific death rate, the constitute proportion to all death caused by tumor and the age-standardized death rate were calculated by taking reference of Chinese standard population or the world standard population. The indexes of mortality were compared with that of previous retrospective surveys of death causes at 1973 - 1975 and 1990 - 1992.
RESULTSThe result showed that during 2004 to 2005, the number died from brain tumor was 4463 and the crude death rate in China was 3.13/100 000, which accounted for 2.30% of the all number died from tumor (193 841 cases). The age-standardized death rate by Chinese standard population was 2.37/100 000 and the age-standardized death rate by the world standard population was 2.90/100 000. Of which, there were 2556 death cases for males with crude death rate of 3.50/100 000. While for females, the crude death rate was 2.74/100 000 (1907 death cases). Age-standardized death rates by Chinese standard population in male and female were 2.71/100 000 and 2.03/100 000 respectively. The age-standardized death rate by world standard population was 3.31/100 000 for male and for female that was 2.48/100 000. The age-specific death rate of brain tumor in China was increasing as age growing. The crude death rates were 3.78/100 000 (1809/47 899 806), 2.80/100 000 (2654/94 760 676), and the age-standardized death rates by Chinese standard population were 2.71/100 000 and 2.20/100 000 for urban and rural area respectively, and the crude death rates of brain tumor in east, middle and west region were 3.60/100 000 (1894/52 556 694), 3.14/100 000 (1565/49 781 225), 2.49/100 000 (1004/40 322 563). The age-standardized death rates by Chinese population were 2.57/100 000, 2.43/100 000 and 2.02/100 000. Compared to the data in the first survey during 1973 to 1975, in which the crude death rate was 1.13/100 000 and age-standardized death rate by Chinese standard population was 1.10/100 000, the crude death rate and age-standardized death rate by Chinese standard population were increased by 176.99% and 115.45% respectively. While compared with the second survey during 1990 to 1992, that crude death rate was 1.89/100 000 and age-standardized death rate by Chinese standard population was 1.74/100 000, the rising percent of the rates were 65.61% and 36.21% respectively.
CONCLUSIONThe level of mortality of brain tumor has been changing with an increasing trend from the period of 1973 - 1975 to the period of 2004 - 2005. The rate in male was higher than that of female with great diversity in different areas in China.

Objective To investigate HPV infection and its correlation with the expression of sur- vivin and proliferating cell nuclear antigen (PCNA) in condyloma acuminatum (CA).Methods HPV6/11 and 16/18 DNA were detected by PCR in 41 cases of CA and 23 specimens of normal skin.The expression of survivin and PCNA was measured by immunohistochemical technique in these two groups. Results The infection rates of HPV6/11 and 16/18 were 87.80% (36/41) and 19.51%(8/41),respective- ly,in CA,and 0 in normal skin epidermis.The expression of survivin and PCNA was found in 53.66% (22/41) and 87.80% (36/41) of CA ,and was 8.70%(2/23)and 47.83% (11/23) in normal skin,respec- tively.The expression of survivin was positively correlated with the high expression of PCNA in CA.The expression of survivin and PCNA was higher in HPV6/11 positive lesions than in HPV6/11 negative lesions. Conclusion HPV infection may up-regulate the expressions of survivin and PCNA,inhibit the apoptosis and promote the proliferation of keratinocytes.
