Objective To investigate the role of nine respiratory pathogens (hereinafter referred to as United Nine Detection(UND)) in acute exacerbation of interstitial lung disease. to provide an evidence of the pathogenesis and effective diagnosis and treatment of AE-ILD. Methods We detected the expression of of IgM antibody of UND in respiratory infection pathogens in serum in the AE-ILD group,the ILD stable group and the normal control group,and observed their dynamic changes. Results The test results of UND showed that the Pathogen-positive rate were 52.1%,27.8%,22%,in 73 cases of the AE-ILD group,72 cases of the ILD stable group and 50 cases of the normal controls,respectively. Statistical analysis showed that pathogen infection rate has statistics difference between the AE-ILD group and the ILD stable group,between the AE-ILD group and the normal control group respectively(P=0.003;P=0.001),while the ILD stable group and the normal control group hadd no significant difference (P = 0.417). The virus positive rates of the three groups were 31.5%,16.7%,10%respectively. Statistical analysis showed that the virus infection rate had statistics difference between the AE-ILD groups and the ILD stable group,between the AE-ILD group and the normal control group(P=0.037;P=0.005). Mycoplasma,influenza B virus,respiratory syncytial virus had high positive rate in these three groups. Dynamic changes of the IgM antibody showed that the positive number of pathogens decreased gradually in long admission of patients with AE-ILD. Conclusions The infection rate of UND in patients with AE-ILD is higher than patients with ILD in the stable stage and the normal controls. It suggests that AE-ILD may be associated with infection.

6 OSAS patients wore the appliance. Polysomnographic monitoring and cephalometric analysis were performed before and after treatment to analyze the effect of the appliance. With the appliance on after one month, the patients felt better. The values of AHI decreased significantly(P<0.01), and the lowest SaO_2 increased significantly(P<0.01).Cephalometric analysis showed a widened airway(P<0.05)after treatment. The results showed that TMJ appliance is an easy and effective treatment of OSAS.

Conclusions FAP was a traditional regimen,combined intrahepatic arterial and intravenous chemotherapy can improve response rate and prolong median survival to metastatic liver cancer .

This study was aimed to reveal the relationship of bronchioloalveolar carcinoma (BAC) syndromes and metastasis, in order to provide new scientific basis for syndrome differentiation, treatment and prognostic assessment, which proved the scientificity and feasibility of internal and external inspection. A total of 60 BAC cases were divid-ed into two groups according to the syndrome of deficiency and excess. Another 30 cases of benign pulmonary nod-ules were simultaneous collected in the physical examination as control group. The quality of life (FACT-L) was scored one day before operation for patients in each group. The thoracoscopic technique was used in the biopsy of targeted tissues, in order to reveal indicators related with metastasis. The results showed that the comparison of FACT-L score of patients from two syndromes of BAC and that of the control group indicated that the score of physi-ological state, social/family condition, emotional condition, functional situation, additional situation and total score of the previous one were obviously higher than the latter one (P < 0.01). And the score of patients in the deficiency syndrome group was higher than that of the excess group with statistical significance (P< 0.01). The comparison be-tween the tumor tissues of patients from two syndromes of BAC and the benign pulmonary nodules showed that the VEGF, MMP-2, MMP-9 of the previous one were higher than the latter one (P< 0.01). The comparison between two syndromes showed that all indexes of the deficiency syndrome were higher than the excess syndrome (P < 0.01). It was concluded that syndromes of BAC was related with metastasis.

Purpose:To find out the clinical biology value of p53 overexpression on Chinese breast cancer by Meta analysis. Methods:Reviewed all the published studies during the recent 10 years regarding p53 and breast cancer, and used standard techniques of Meta-analysis to combine the results of these studies to produce a more precise estimate of the prognostic significance of p53 mutations.Results:the mean of p53 positive express was 45%,95% confidence interval (43-47)%:, p53 positive was related with node metastasis, recurrence after surgery, over survival, tumor size and nuclear grade, but not related with age and pathology type, p53 was a special and sensitive prognostic factor for breast cancer.Conclusions:p53 can be an independent molecular marker to definitive prognostic of breast cancer, and possibly can be a reliable marker for choice of standard and individulized therapy.

BACKGROUND: Multiple applications of opium medicines can induce the accommodative changes of morphology and function in some intracerebral nerve positions. These accommodative changes are important neurobiological bases inducing drug-desire and re-addiction after detoxification. However, the actual molecular mechanism is unclear at present.OBJECTIVE: To investigate the impacts of the generation of heroin-dependence and detoxification on brain-derived neurotrophic factor (BDNF) in rat to provide a laboratorial gist for the participation of BDNS in heroin-dependence and detoxification.DESIGN: A randomized controlled study by employing experimental animals as subjectsSETTING: Mental health center of a medical university affiliated hospital MATERIALS: The study was conducted in the Laboratory of Pharmacology,Faculty of Pharmacology, Chongqing Medical University between March 2004and July 2004. Totally 30 inbreeding clean male SD rats with a bodymass between 200 g and 250 g were obtained from the Experimental Animal Center of the Third Military Medical University of Chinese PLA. Rats were randomly divided into blank control group(control group), heroin-dependent group (heroin group), and naloxone detoxification group(naloxone group) with 10rats each.METHODS: Morphine was subcutaneously injected into the rat with dose-increasing method to establish heroin-dependence rat model. Rats of naloxone group received subcutaneously injection of 2 mg/kg of naloxone to excite abstinent symptoms. The same dose of normal saline (NS) was injected in rats of control group. Model rats of each group were observed biologically and behaviorally. BDNF expression at different brain zone of rats in three different groups was tested with immunohistochemistry and digoxin-labeled oligonucleoide probe in situ hybridization technique.Comparison of the evaluation of abstinent symptoms in rats of each group.RESULTS: In the heroin group, the relative content of BDNF protein was higher in frontal lobe cortex, locus caeruleus and hippocampus than that of the control group( P ＜ 0.05); BDNFmRNA relative content was higher in frontal lobe cortex than that of the control group( P ＜ 0. 05) . In naloxone group, BDNF and its mRNA relative contents in frontal lobe cortex, locus caeruleus and hippocampus were higher than that of heroin group and control group ( P ＜ 0.05 ).CONCLUSION: Chronic administration of heroin could affect BDNF protein and its mRNA expressions in the corresponding brain areas of the rats, which suggests that the change of BDNF expression participates in heroin-dependence and detoxification.

[Summary] SIRT3 is a member of the silent information regulator 2 ( Sir2) family, located in the inner mitochondrial membrane, with a strong effect of deacetylation. SIRT3 not only modulates energy metabolism, cell apoptosis, tumor growth, anti-aging etc. , but also plays an important role in the field of cardiovascular diseases. In this review, we summarize recent findings related to SIRT3 with metabolic syndrome and cardiac hypertrophy, to provide a theoretical basis for the further study on the potential role of SIRT3 in cardiovascular diseases.

Objective To investigate the probable risk factors for type 2 diabetic patients complicated nonalcoholic fatty liver disease (NFLD)in elderly, through comparing the body composition, serum lipid profile, incidences of abdominal obesity and metabolic syndrome (MS) between elderly type 2 diabetic patients with and without NFLD. Methods The enrolled elderly type 2 diabetic patients were divided into NFLD group (n=83) and non-NFLD group (n=85). Their clinical data including body composition, serum lipid profile, incidences of abdominal obesity and MS were analyzed retrospectively and compared. Results Compared with non-NFLD group, the BMI [(26.9±2.5) kg/m~2 vs. (24.1±2.5) kg/m~2, P=0.000], waist-hip ratios (WHR) ((0.92±0.07) vs. (0.87±0.06), P=0.000], total body fat percentage [(29.6%±6.6%) vs. (25.3%±5.5%),P=0.000], abdominal fat [(11.0±2.5) kg vs. (8.7±2.3) kg, P=0.000], visceral fat [(3.0±0.7) kg vs. (2.3±0.6)kg, P=0.000], visceral fat area [(97.6±22.2) cm~2 vs. (75.5±21.1) cm~2,P=0. 000], serum triglyceride [(1.98±0.94) mmol/L vs. (1.22±0.61) mmol/L, P=0.000]were all increased, while serum HDL [(1.23±0.32) mmol/L vs. (1.40±0.37) mmol/L, P=0.002]was decreased in NFLD group. The incidences of over-body fat (68.7% vs. 36.5%, P=0. 000),dyslipidemia (47.0% vs. 21.2%, P=0. 000), abdominal obesity (69.9% vs. 43.5%, P=0.001) and MS (49.4% vs. 9.6%, P=0.000) were obviously increased. But there were no statistical differences in serum TC [(4.93±0.94) mmol/L vs. (4. 73±1.07) mmol/L, P=0.219]and LDL [(3.23±0.80) mmol/L vs. (3. 07±0.89) mmol/L, P=0. 229]between the two groups. Logistic regression showed that high BMI (β=1.268, P=0.000, OR=3.56), over-total body fat percentage (β=0.902, P=0.023, OR=2.47)and the existence of MS (β=1. 664, P=0. 000, OR=5.28) were related to elderly type 2 diabetic patients complicated NFLD. Conclusions The high BMI, over-total body fat percentage are related to elderly type 2 diabetic patients complicated NFLD, and NFLD is probably one of components of metabolic syndrome.
