Background Granulocyte colony-stimulating factor(G-CSF)has been reported to have beneficial effect on cardiac dysfunction in post infarction and doxorubicin-induced cardiomyopathy.Objective To investigate the effects of G-CSF on cardiac remodeling in cardiac hypertrophy induced by angiotensin Ⅱ(Ang Ⅱ).Methods Thirty-six male wild type mice(WT)were allocated randomly to receive subcutaneously G-CSF(10 ?g/kg per day, n=9),or Ang Ⅱ(2.88 mg/kg per day,n=9),or Ang Ⅱ plus G-CSF(Ang Ⅱ 2.88 mg/kg+G-CSF 10 ?g/kg,n =9)for 4 weeks with untreated WT(n=9)as controls.Blood pressure and cardiac function were measured. Heart weight/body weight ratio,myocyte cross-sectional area and fibrosis area were determined.The mRNA ex- pression of osteopontin(OPN)in myocardium was detected by RT-PCR.The expressions of angiotensin converting enzyme(ACE),ACE2 and phosph-p70S6 kinase protein in myocardium were assessed by Western-Blot.Results Ang Ⅱ significantly elevated blood pressure(SBP,Ang Ⅱ:139.7?1.6 vs WT:108.7?2.3 mmHg,P0.05),but significantly attenuated the myocyte cross-sectional area(Ang Ⅱ+G-CSF:181.06?0.11 vs Ang Ⅱ:202.02?0.16 ?m~2,P

OBJECTIVETo assess the effectiveness and safety on post-stroke dysphagia in chronic stage treated with magnetic-ball sticking therapy at the auricular points.

METHODSNinety cases of post-apoplexy dysphagia in chronic stage were randomized into an auricular points group and an acupuncture group. In the auricular points group, the magnetic-ball sticking therapy was applied to subcortex (pizhixia, AT4), brainstem (naogan, AT(3,4i)), mouth (kou, CO1), cheek (mianjia, LO(5,6i)), tongue (she, LO2) and throat (yanhou, TG3) on one ear each time, and were changed on the other ear once every 3 days. In the acupucnture group, acupuncture was applied to Feng-chi (GB 20), Yifeng (TE 17), Shanglianquan (Extra), Jinjin (EX-HN 12), Yuye (EX-HN 13), Shuigou (GV 26) and Tongli (TH 5), etc. The needles were retained for 30 min in each treatment. The treatment was gi-yen once a day in the two groups and the treatment of 6 days made one session. There was 1 day at an interval among the sessions. Totally, 3 sessions of treatment were required. The video fluoroscopic swallowing study (VFSS) was performed for 4 kinds of food with different properties and shapes in each patient. The main indices were Rosenbek penetration-aspiration score, oral-retaining score and throat-retaining score. The efficacy, and the incidences of aspiration pneumonia and malnutrition were compared between the two groups. The nutrition indices were compared before and after treatment between the two groups, such as the skinfold thickness of triceps brachii muscle, serum albumin and peralbumin.

RESULTSIn 21 days of treatment, in the auricular points group, the 1 mL liquid loversol Rosenbek penetration-aspiration score (1.51 +/- 0.69), oral-retaining score (1.17 +/- 0.38) and throat-retaining score (1.30 +/- 0.66) were all lower than those (2.51 +/- 0.67, 1.63 +/- 0.72, 1.67 +/- 0.7) in the acupuncture group separately. The 10 mL liquid loversol Rosenbek penetration-aspiration score (2.27 +/- 0.65), oral-retaining score (1.60 +/- 0.50) and throat-retaining score (1.49 +/- 0.51) were all lower than those (4.19 +/- 0.73, 2.30 +/- 0.51, 2.41 +/- 0.50) in the acupuncture group separately. The 10 mL paste loversol Rosenbek penetration-aspiration score (1.68 +/- 0.81), oral-retaining score (1.11 +/- 0.31) and throat-retaining score (1.10 +/- 0.31) were all lower than those (3.91 +/- 0.68, 1.63 +/- 0.76, 1.60 +/- 0.76) in the acupuncture group separately. The 1/4 cake-form loversol Rosenbek penetration-aspiration score (2.60 +/- 0.65), oral-retaining score (1.40 +/- 0.50) and throat-retaining score (1.74 +/- 0.49) were all lower than those (4.14 +/- 1.10, 2.40 +/- 0.73, 2.30 +/- 0.83) in the acupuncture group separately. The incidence of aspiration pneumonia was 14.9% (7/47) in the auricular points group, which was lower than 55.0% (22/40) in the acupuncture group (P < 0.01). The incidence of malnutrition was 8. 5% (4/47) in the auricular points group, which was lower than 50.0% (20/40) in the acupuncture group (P < 0.01). In 21 days of treatment, the results of the skinfold thickness of triceps brachii muscle and serum albumin in the auricular points group were better than those in the acupuncture group (both P < 0.05).

CONCLUSIONThe magnetic-ball sticking therapy at auricular points achieves the definite efficacy on post-stoke dysphagia in chronic stage and decreases the incidences of aspiration pneumonia and malnutrition. The efficacy of this therapy is better than acupuncture.

Low frequency sensorineural deafness is a common subtype of idiopathic sudden deafness. Certain patients suffered recurrent attacks without vertigo, much alike Meniere's disease. Few of them developed into definite Meniere's disease during long-term follow-up in many clinical studies. Although the pathophysiology of recurrent low frequency deafness is yet unknown, the desease is considered associated with early state of endolymphatic hydrops or migraine. Otologists shall be aware of its clinical course and careful explanation is necessary at time of initial informed consent.

Objective To investigate the expression of HIF-1α and P-gp protein in pancreatic carcinoma and determine their clinicopathological significance and the correlation between the expression of HIF-1α, P-gp and the clinical prognosis. Method In samples from 74 cases of pancreatic carcinoma and 10 healthy individuals, the expression of HIF-1α and P-gp were detected by immunohistochemical method. Results The positive expression rate of HIF-1α and P-gp was 75.7% and 86.5%,respectively, which were remarkably higher than that in normal pancreatic tissue (P＜0.05). There was a positive correlation between the expression of HIF-1α and that of P-gp. The aberrant expression of HIF-1α and P-gp was associated with lymph node metastasis but not the location, size, clinical stages and nerve invasion of the tumor. Patients with high intensity of HIF-1α and P-gp expression showed a significantly lower median survival time than those with low intensity expression.Conclusions The expression of HIF-1α and P-gp is up-regulated in pancreatic carcinoma and there is a positive correlation between them. The expression of HIF-1α and P-gp might be related to the lymph node metastasis and poor prognosis.

Objective To study the clinical value of wrist magnetic resonance imaging (MRI) combined anti-cyclic citrullinated peptide antibody detection in the diagnosis of early rheumatoid arthritis (RA).Methods Forty five patients with early RA were selected as RA group,45 cases of patients without rheumatoid arthritis as non-RA group,and 43 cases of people with normal examination as control group.All subjects were given wrist MRI and anti-cyclic citrullinated peptide (CCP) antibody with the enzyme linked immunosorbent assay (ELISA).At the same time,clinical symptoms,physical signs,MRI manifestations,and laboratory indicators were collected.All results were statistically analyzed.Results Positive rate of MRI lesions and serum anti-CCP antibody in RA group were significantly higher than non-RA group and control group (P ＜0.05).The sensitivity and specificity of MRI (or anti-CCP antibody) for early RA were 88.88％ and 82.22％ (or 68.88％ and 91.11％).The sensitivity (64.44％) of MRI combined with anti-CCP antibody was decreased compared to individual; however,the specificity (100％) of MRI combined with anti-CCP antibody was increased.The correlation of MRI synovial scores and anti-CCP antibody levels was positively correlated (rs =0.612,P ＜ 0.05).MRI abnormal signs and joint disease activity score (DAS28) were positively correlated (rs =0.521,P ＜ 0.05).Anti-CCP antibody levels and DAS28 were positively correlated (rs =0.541,P ＜ 0.05).Conclusions MRI examination and combined with anti-CCP antibody detection is helpful to improve the diagnosis of early RA,and it provides a detection basis for dynamic assessment of RA condition changes.

Objective To investigate the differences of pre-hospital delay time in acute ST-elevation myocardial infarction (STEMI)between the advanced age group(>75 years old)and control group(≤75 years old).Methods Four hundreds patients with STEMI in the cardiology and emergency departments of the First Affiliated Hospital and Affiliated Luoyang Central Hospital of Zhengzhou University from January 2013 to March 2015 were selected and divided into two groups according to the age,the ad-vanced age group (>75 years old)and control group(≤75 years old).The patients′data were inquired and recorded for conducting the statistical analysis.Results The proportion of pre-hospital delay time < 6 h in the advanced age group was significantly lower than that in the control group and the time for conducting coronary angiography was longer than that in the control group,the differences were statistically significant(P <0.05).The mortality rates of intra-hospital,on 30 d and half a year after discharge in the advanced age group were higher than those in the control group,the differences between the two groups were statistically signif-icant (P <0.05).Conclusion The advanced age patients receiving active therapy are relatively less,which is mainly due to the wor-ry on the age related adverse reactions.
