Objective To investigate the changes of autonomic nerve function of coronary heart disease (CHD) patients with panic disorder(PD). Methods All the subjects who met with the diagnostic code of CHD and PD were divided into CHD group(n=40) ,PD group(n=36) ,comorbid CHD and PD group(n=27) ,and 40physical examinee were recruited as normal control group. They had a 24 hours Holter ECG monitoring by time and frequency domain analysis of heart rate variability. ANOVA analysis was utilized to statistic the collected data. Results Compared with normal controls,the patients of others groups had every indexs of HRV were reduced. The indexs of HRV of comorbid CHD and PD were lower than the patients of CHD or PD group. The score of time domain SDNN(70.40 ± 14.74)ms,SDANN(91.72 ± 24.46)ms,PNN50(2.83 ±2.07)%, RMSSD( 15.66 ±7.45)ms,frequency domain LF(647.54 ± 129.24)ms2, HF(596. 16± 127.66) ms2 in comorbid CHD and PD. There were significant differences with others groups(P ＜ 0.05 ). Conclusion The autonomic nervous functional of the patients with CHD and PD were in disorder. The autonomic nervous functional disorder of the patients with comorbid CHD and PD was more severe.

Objective To investigate the effect of rosiglitazone (RGTZ) on anti-oxidation in aging rat kidney. Methods Twenty-four-month-old male Sprague-Dawley rats were randomly divided into three groups (n=10): control group (CON), rosiglitazone group (RGTZ) and caloric restriction group (CR). The CON rats were allowed ad libitum access to feed and tap water.The RGTZ rats received intragastric administration of RGTZ (4 mg·kg-1·d-1),and the CR rats were provided with a vitamin and mineral fortified version of the same diet at a level of 40% less food (by weight) than the CON rats. After 12 weeks all the animals were sacrificed by decapitation, and both the body weight and the percentage of kidney and heart in each group were measured.Western blot was performed to analyze the expression of PPARγ protein. The content of MDA and the activity of SOD and GSH-PX in kidney tissue were detected. Besides, frozen sections of kidney tissue were stained for senescence-associated-13 galactosidase (SA-β-Gal). Results The body weight of CR rats decreased obviously, in contrast, which did not change in CON and RGTZ group. Percentage of kidney and heart to body weight was normal in CR or RGTZ group after intervention. Western blot result showed that PPARγ protein expression in rat kidney was significantly higher in RGTZ and CR group as compared to CON group (P<0.05). Compared with RGTZ and CR rats, obviously lower activities of SOD and GSH-Px were noted in CON rats, however, the content of MDA was higher in CON rats. Additionally, the positive staining area of [3-Gal in CR and RGTZ group was significantly smaller than that in CON rats (P<0.05, P<0.01 ). Conclusion RGTZ can defer the kidney aging in senescence SD rat, and the mechanism may be related to amelioration of oxidative damage and enhancement of antioxidation.

Objective To observe the month age distribution of peroxisome proliferators activated receptor gamma (PPARγ) expression in rat kedney. Methods Wistar rats aged 3 months,12 months and 24 months were made as models who represented young, middle-aged and old group respectively. Western blotting, immunohistochemical (IHC) and in-situ hybridization (ISH) were used to detect the expression and location of protein and mRNA of PPARγ in rat kidney. Results Western blotting results showed that the expression of PPARγ protein was higher in 3 months group than in 24 months group (0.94±0.05 vs. 0.78±0.02, P＜0.01) and 12 months group (0.87±0.04, P＞0.05), and it reduced in 24 months group than in 12 months group (P＞0.05). By IHC,the PPARγ protein was localized predominantly in the nuclear of tubular epithelia and collecting duct cells in each group. In old age group, PPARγ protein was also detected little in the mesangial and Bowman's capsule epithelial cells. Meanwhile, the distribution of PPARγ mRNA with ISH was consistent with above findings. Additional, semi-quantitative analysis of ISH results verified that the level of PPARγ mRNA decreased with ageing. Conclusions As a nuclear transcription factor,PPARγ participates in the regulation of rat kidney aging.

Objective To evaluate the significance of the expression of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) as prognostic indicators for patients with stage Ⅱ colorectal cancer. Methods A total of 285 patients with stage Ⅱcolorectal cancer who underwent potentially curative surgery were enrolled in the study. A high CEA level was defined as a level exceeding 5 ng/ml and a high CA19-9 level was defined as a level exceeding 37 U/ml. Patients were followed up every 3 months to review CEA and CA19-9 levels. Two years later, the chest and abdominal CT examination were performed every 3 months, and then every 6 months until 5 years. Results Out of these 285 patients, 99 (42.60%) patients had high CEA levels, 25 (8.77 %) patients had high CA19-9 levels, and 12 (4.21 %) patients had both high CEA and CA19-9 levels. The overall survival rates of patients with both high CEA and CA19-9 levels were significantly worse than those of others (P< 0.05). During the study, 51 recurrences were diagnosed. There were 22 hepatic recurrences, 10 pulmonary recurrences, 9 local recurrences, 8 lymph node recurrences, and 2 peritoneal recurrences. CT, CEA and CA19-9 were the first abnormal examinations in 30, 5 and 8 recurrent patients, respectively. In 27 % of recurrent patients, the recurrence was detected earlier by CEA and CA19-9 than that by CT. Conclusions The detection of preoperative CEA and CA19-9 levels is useful for predicting the prognosis after potentially curative surgery in patents with stage Ⅱ colorectal cancer. For early detection of occult recurrence of colorectal cancer, tumor markers are relevant.

Objective: To evaluate the post-operative mortality of left ventricular end-diastolic pressure (LVEDP) during primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: We retrospectively analyzed 255 patients with new onset of STEMI who received primary PCI in our hospital and all patients received LVEDP measurement before coronary artery opening. According to LVEDP value, the patients were divided into 2 groups: LVEDP≤14 mmHg group,n=155 and LVEDP>14 mmHg group,n=100. The post-operative mortality up to 6 months was observed, and the effect of LVEDP on death rate was studied by Cox regression analysis. Results: Compared with LVEDP≤14 mmHg group, the patients in LVEDP>14 mmHg group had the 6 months mortality at HR=4.26, 95% CI (1.13-16.08),P=0.03. Relevant study presented that LVEDP was slightly related to LVEF (r=-0.267, P=0.001) and BNP (r=-0.154,P=0.041). Multi-regression analysis indicated that with adjusted LVEF and BNP, LVEDP was the independent predictor for post-operative mortality up to 6 months in acute STEMI patients after PCI. Conclusion: The LVEDP value measured during PCI procedure is the independent predictor for mortality after PCI in patients with new onset of STEMI.

OBJECTIVETo seek the optimum treatment for patients with primary gastric non-Hodgkin's lymphoma and factors associated with prognosis.

METHODSA retrospective study was conducted on 157 primary gastric non-Hodgkin's lymphoma patients who had received operation for 45 years.

RESULTSThe X-ray diagnosis rate was 39.4% before operation. The diagnosis rate by gastroscopy was 52.7%. Among the 157 patients, 32 belonged to stage I(E), 40 stage II(E), 29 stage III(E), and 56 stage IV(E). All of the patients were received chemotherapy or radiation. The 3-, 5-, 10-, 15-year survival rates were 51.1% (69/135), 42.3% (55/130), 20.7% (23/111), and 13.5% (14/104).

CONCLUSIONSThe 3-, 5-year survival rates in stage I(E) and stage II(E) were 2 to 5 times higher than those in stage III(E) and IV(E) (P < 0.01). The 3-, 5-year survival rates of primary gastric non-Hodgkin's lymphoma were 60.2% (65/108) and 50.0% (52/104) respectively. The prognosis was better than the 5-year survival rate of gastric cancer patients with D(2) lymphodenectomy (33.3%). Early diagnosis and treatment are effective to prevent complications, enhance quality of patient's life, and prolong the survival.

Caroli disease is a rare congenital disorder characterized by nonobstructive dilatation of intrahepatic ducts. In cases with symptomatic intrahepatic manifestations, treatment should correspond to the type with hepatic resection for localized disease and transplantation for diffuse forms. If possible, complete resection of the cysts can cure the symptoms and avoid the risk of malignancy. A 66-year-old woman presented to Wuxi Xishan People's Hospital with recurrent intermittent upper quadrant abdominal pain. Further examinations suggested the diagnosis of Caroli disease limited to the left hepatic lobe. She underwent laparoscopic hepatectomy. Pathological examination confirmed the diagnosis of Caroli disease, and no malignancy was found. There were no immediate complications and no long-term complications after one and one-half years of follow-up. Laparoscopic hepatectomy could be a feasible, safe treatment option for localized Caroli disease.

Renal collecting duct carcinoma(CDC) is rare in clinic, complicated with clear cell renal cell carcinoma(ccRCC) of one kidney is extremely rare. We reported a case CDC complicated with ccRCC of one kidney. The patient was admitted as left low back pain and gross hematuria, preoperative CT examination showed that one tumor was found in the upper middle pole and another tumor at lower pole of the left kidney, and multiple enlarged lymph nodes in the medial edge of the kidney. CT diagnosis was renal collecting duct carcinoma complicated with clear cell carcinoma of the left kidney, retroperitoneal lymphatic metastasis and underwent radical nephrectomy. Postoperative pathological diagnosis was CDC(upper middle pole) complicated with ccRCC(lower pole)of the left kidney. The patients were treated with sunitinib for 6 months and survived 13 months, and died of extensive metastasis.

BACKGROUNDThe emergency department (ED) has a pivotal influence on the management of acute heart failure (AHF), but data concerning current ED management are scarce. This Beijing AHF Registry Study investigated the characteristics, ED management, and short- and long-term clinical outcomes of AHF.

METHODSThis prospective, multicenter, observational study consecutively enrolled 3335 AHF patients who visited 14 EDs in Beijing from January 1, 2011, to September 23, 2012. Baseline data on characteristics and management were collected in the EDs. Follow-up data on death and readmissions were collected until November 31, 2013, with a response rate of 92.80%. The data were reported as median (interquartile range) for the continuous variables, or as number (percentage) for the categorical variables.

RESULTSThe median age of the enrolled patients was 71 (58-79) years, and 46.84% were women. In patients with AHF, coronary heart disease (43.27%) was the most common etiology, and myocardium ischemia (30.22%) was the main precipitant. Most of the patients in the ED received intravenous treatments, including diuretics (79.28%) and vasodilators (74.90%). Fewer patients in the ED received neurohormonal antagonists, and 25.94%, 31.12%, and 33.73% of patients received angiotensin converting enzyme inhibitors/angiotensin receptor blockers, beta-blockers, and spironolactone, respectively. The proportions of patients who were admitted, discharged, left against medical advice, and died were 55.53%, 33.58%, 7.08%, and 3.81%, respectively. All-cause mortalities at 30 days and 1 year were 15.30% and 32.27%, respectively.

CONCLUSIONSSubstantial details on characteristics and ED management of AHF were investigated. The clinical outcomes of AHF patients were dismal. Thus, further investigations of ED-based therapeutic approaches for AHF are needed.
