Objective To observe the effect of psychological intervention on dysphagia after stroke complicated with depression. Methods 60 cases with dysphagia complicated with depression were divided into treatment and control groups. Based on the nountine nursing and swallowing function training, the treatment group received psychological intervention. They were assessed with multimodel approach to diagnosis of post stroke depression (MMADD) and drinking test before and after treatments. Results The scores of drinking test and MMADD inside symptom in treatment group were lower than that of control (P<0.05). Conclusion The psychological intervention at early stage can facilitate the recovery of swallowing dysfunction and depresson after stroke.

AIM: To explore the effects of peroxisome proliferator-activated receptor γ (PPARγ) on the activity and expression of γ-glutamylcysteine synthetase (γ-GCS), and its role in rats with chronic obstructive pulmonary disease. METHODS: COPD model was established by the method of combining fumigation and lipopolysaccharide (LPS) intra-tracheal dripping. Meanwhile, some of the COPD rats were administered with rosiglitazone (RGZ), a PPARγ activator. The pulmonary function and the pathological changes were determined. ROS content and γ-GCS activity in lung tissues were detected. The levels of PPARγ, γ-GCS mRNA and protein expression in lung tissues were measured by immunohistochemistry, Western blotting, in situ hybridization (ISH) and reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: The pulmonary function (FEV_(0.3), FEV_(0.3)/FVC%, PEF) were significantly improved in RGZ group compared to COPD group. Under light microscope, lung pathological changes in COPD group conformed to pathological features of COPD. The pathological changes of lung tissue were obviously reduced in RGZ group compared to COPD group. In RGZ group, ROS content was obviously reduced and γ-GCS activity significantly increased compared to COPD group. Protein and mRNA expressions of PPARγ and γ-GCS in COPD group significantly higher than those in control group (all P<0.01), and those in RGZ group was markedly increased compared to COPD group (all P<0.05). Linear correlation analysis showed that PPARγ protein was positively correlated with γ-GCS activity (r=0.634, P<0.01), and was no significantly correlated with ROS content (r=0.214, P>0.05). PPARγ protein was positively correlated with γ-GCS protein and mRNA (r=0.553, r=0.442, all P<0.01). CONCLUSION: PPARγ activation by RGZ reduces the extent of COPD oxidant/antioxidant imbalance, which plays an important role in the prevention and treatment of COPD. In addition, PPARγ may play an important antioxidant protection role by reducing ROS production, and increasing activity and gene expression of γ-GCS in the lung.

Objective To investigate the effect of stellate ganglion block(SGB)on heart mte variability (HRV)during thyroidectomy performed under cervical plexus block.Methods Forty-five ASA Ⅰ or Ⅱ pafients of both sexy8(8 males,37 females) aged 20-60 yr,weighing 40-70 kg undergoing elective thyroidectomy under cervical plexus block were randomly divided into 3 groups(n=15 each):group Ⅰ control,group Ⅱ left SGB and group Ⅲ right SGB.The parameters of HRV included low frequency(LF),high frequency(HF),LFnu,HFnu and LF/HF ratio.SBP,DBP,HB and HRV parameters were recorded before anesthesia(To,baseline),immediately(T1) and at 5 and 10 rain after cervical plexus block(T2,T3),at the beginning and end of operation (T4,T5).Results SBP and DBP were significantly increased at different time points after cervical plexus block in all 3 groups.Compared with the baseline at T0,LFnu and LF/HF ratio were significantly increased while HR,HF and HFnu decreased during operation in group Ⅰ,LF,HF and HFnu were significantly decreased while HR increased during operation in group Ⅲ(P<0.05),but no significant change in HRV parameters was found during operation in group Ⅱ(P>0.05).Compared with group Ⅰ,HR and LFnu were significantly decreased while HF and HFnu increased in group Ⅱ(P<0.05),but no significant change was found in the indexes mentioned abovein group Ⅲ (P>0.05).Conclusion SGB can adjust cervical plexus block-induced sympathetic excitability and maintain the balance between sympathetic and parasympathetic tension.Left SGB outweighs right SGB.

Objective To analyze the concomitant malforrnations,chromosomal abnormalities and outcomes in prenatally diagnosed congenital diaphragmatic hernia (CDH) cases. Methods Cases of fetal CDH,prenatally identified in the First Affiliated Hospital of Sun Yat-sen University from January 2002 to November 2008,were recruited.The concomitant realformations,chromosomal abnormalities and outcomes of fetal CDlH were analyzed.Fisher's exact test was applied. Results During the study period,71 CDH cases were identified including 62(87.3%) left-sided CDH and 9 (12.7%) right-sided ones.Among the 71 CDH fetuses,38(53.5%)were isolated CDH.33 (46.5%)were complicated with other realformations(complex CDH),including 18(54.5 0A) cardiovascular defects,10 (30.3%)central nervous system abnormalities,9(27.2 0A)genitourinary abnormalities and others.Fetal karyotying was performed in 19 out of the 71 CDH fetuses.among which 12 were isolated CDH cases with normal karyotype,and 4 of the rest 7(4/7)complex CDH cases with chromosomal abnormalities showing a significant differenee compared to the isolated CDH (P.0.009).Sixty-five pregnancies were terminated including all complex CDH(n=33)and 32 isolated CDH.The rest 6 isolated CDH fetuses were term delivered and 5 of them survived after repair of diaphragmatic hernia and one died after birth. Conclusions Left-sided CDH are more common than right-sided ones. Approximately half of the CDH cases are complicated with other malformations,especially cardiovascular abnormalities.The risk of chromosomal abnormalities increases in complex CDH and is relatively low in isolated CDH.The influence of surgical procedure on the prognosis of CDH has not yet determined.

Objective:To study the change of plasma cyclic nucleotide in patients of rheumatic heart disease with pulmonary hypertension and to evaluate the relationship between plasma cyclic nucleotides and hemodynamics. Methods:Plasma cGMP and cAMP were examined by radioimmunoassay, hemodynamic data were obtained with Swan Ganz catheter and the HP compact configurable monitors. Results:Plasma cyclic nucleotide increased in patients of rheumatic heart disease with pulmonary hypertension and had an obvious correlation with the level of PAPM, PVR, PAWP and CI. Conclusion:Increased cAMP and cGMP is one of the pathophysiological characters of pulmonary hypertension, cAMP and cGMP, as the second messenger, may play an important regulating role in the development of pulmonary hypertension.

Objective: To observe the clinical effect of oral nutrition supplementation for maxillofacial tumor patients before operation. Methods: 60 patients who suffered from maxillofacial neoplasm were divided into two groups. In observation group, on basis of routine diet, oral nutrition supplements (Fortisip) had been added for 5~7 days before operation. In control group, only routine diet had been supplied. After operation, the two groups were all supplied with tube feeding. The blood routine test, plasma total protein, albumin, pre albumin and lymphocyte count were measured in all patients. Results: Every biochemical item reduced significantly after operation and no statistical significance was found between groups. But the absolute decreasing values had significant difference between the groups. Conclusions: Oral nutrition supplements (Fortisip) contains balanced nutrients and tastes well. It is safe and effective to use a nutritional supplement, being helpful to prevent malnutrition and to improve the immune function in perioperative period of patients with maxillofacial neoplasm.

Objective To investigate the effect of promoter hypermethylation of O 6 methylguanine DNA methyltransferase (MGMT) gene on colorectal tumorigenesis and progression. Methods The promoter hypermethylation of O 6 methylguanine DNA methyltransferase gene was assayed in 27 sporadic colorectal adenomas, 62 sporadic colorectal carcinomas and 20 normal colorectal mucosa tissues by methylation specific PCR. At the same time, the expression of MGMT protein was studied in the same samples using immunohistochemistry. Results None of the normal colorectal mucosa tissues showed methylated bands. Promoter hypermethylation was detected in 40.7%(11/27) of adenomas and 43.5% (27/62) of carcinomas, respectively. MGMT proteins were expressed in nucleus and cytoplasm of normal colorectal mucosa tissues. Loss of MGMT expression was found in 22.2% (6/27) of adenomas and 45.2% (28/62) of carcinomas, respectively. There were significant difference among them ( P =0.041). Methylation was detected in 5 of the 6 adenomas( P =0.027) and 24 of the 28 carcinomas( P
