Objective To investigate the long-term prognosis an d recorery of children with juvenile rheumatoid arthritis(JRA).Methods The cases diagnosed JRA in our hospital over the period of 1988～1992 we re followed up for the conditions of disease,the deteriorated joints,the treatme nt and the living conditions of patients.Results Ninty-six ca ses were followed up(involving male 66 cases,female 29 cases,the mean age of on set 8.21?3.17 years )except for a case who died of lymphoma.There were 44 cases with systemic JRA ,2 cases of them died after 7-years onset and 23 cases developed severe destructive arthritis.There were 38 oligoarthritis cases,27 cases of them stiu had active disease during 10-year following-up and 9 cases were diagnosed sacroiliitis.There were 13 polyarthritis and 3 cases of them were RF positive, who had developed severe destructive arthritis.Conclusions The prognosis of juvenile rheumatoid arthritis is not desirable,especially in systemic JRA,whose prognostic factors are related to age of onset,the lasting of fever,the markers of phlegmasia activity and the condition of systemic involvement and treatment.Oligoarthritis about 30 % may develop into ankylosing spondylitis.The probability of destructive arthritis is hi gher in polyarthritis with more RF positive and poor prognosis.

Objective To investigate the impact of diabetes on coronary artery bypass grafting (CABG)in peroperative patients. Methods Clinical data of 692 CABG patients were collected retrospectively from Sep. 2006 to Jul. 2010. The CABG patients were divided into diabetic group (n = 276) and nondiabetic group (n = 416) according to with the status of diabetes or not before operation. Blood glucose was dynamicaly monitored and treated with insulin to control blood glucose in perioperativeperiod. The postoperative effect,perioperative complication and inhospital case fatality and their relationship with diabetes were analyzed using univariate analysis. Results No significant differences were found regarding the incision complications (5. 8%vs. 4. 3 % , P > 0. 05). The volume of blood transfusion was (890. 7 ± 520. 6) ml in the diabetes group, which was not significantly different from that of (825. 2 ±518. 4)mlin the non-diabetes group (P>0. 05). No significant difference was found on cardiac arrhythmia (13.0% vs. 13. 5%),renal function insufficient (5. 1% vs. 2.4%)and case fatality (2. 9% and 1. 9%) between the diabetes and non-diabetes group (Ps >0. 05). In the diabetes group and non-diabetes group, the duration of IABP (3.7 ± 1. 6) d vs (3.5 ± 1.6)d, use of ventilator (2. 6 ± 1.9)d vs. (2. 4±1.5)d were not sigfnificantly different (Ps >0.05). The length of hospital stay and cost were (22. 0 ±8. 8)d and (8. 11 ±2. 40) thousand RMB in the diabetes group, which were significantly higher than that of (20. 6 ±7. 6)d and (7. 63 ±2. 20) thousand RMB in the non-diabeties group (t =2. 22 and 2. 71 ,Ps <0.05) . Conclusion There are no significant differences in the operative case fatality and complications between patients with diabetes and without nondiabetes. However,diabetes increases hospital stay and expense.

OBJECTIVETo analyze the fungal composition in Massa Medicata Fermentata based on culture dependent method and independent PCR-SSCP technique.

METHODFungi were directly isolated from Massa Medicata Fermentata samples. The obtained strains were identified according to morphology and DNA sequence. Meanwhile the total fungal DNA was extracted from Massa Medicata Fermentata samples, the cultural independent PCR-SSCP technique based on β-tubulin gene were used to identify the mycobiota.

OBJECTIVE: To investigate the immunoregulation and short-term therapeutic effects of super-selective intra-arterial chemotherapy combined with Fuzheng Kang'ai Granules, a compound Chinese herbal medicine, on patients with late gastric cancer. METHODS: Forty patients with late gastric antrum cancer were randomly divided into study group and control group. Patients in the study group were orally administered Fuzheng Kang'ai Granules 48 hours after the first super-selective left gastric artery chemotherapy with high-dose drugs (EAP regime: VP(16) 100 mg/m(2) + epirubicin 60 mg/m(2) + carboplatin 200 mg/m(2)), while patients in the control group were only administered the same local artery chemotherapy as in the study group. RESULTS: The short-term therapeutic efficacy in the study group and control group were 82.5% and 57.5% respectively (P<0.01). The occurrence rates of side effects in the study group were significantly lower than those in the control group (P<0.01). The Karnofsky score of life quality of the study group was obviously higher than that of the control group after treatment (P<0.05). The half survival time and one year survival rate in the study group and control group were (24.9 +/- 1.36) month, 70% (28/40) and (13.7 +/- 0.72) month, 35% (14/40) respectively. They were significantly improved in the study group compared with the control group (P<0.01). The levels of cytokines interleukin 2 (IL-2), tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma) after treatment in the study group were significantly higher than those before treatment (P<0.05 or P<0.01), as well as than those after treatment in the control group (P<0.01). On the other hand, the level of immune inhibitory factor soluble interleukin-2 receptor (sIL-2R) after treatment in the study group was lower than that before treatment, as well as than that after treatment in the control group (P<0.01). CONCLUSIONS: The super-selective intra-arterial chemotherapy combined with Fuzheng Kang'ai Granules has good short-term therapeutic efficiency and few side effects for patients with late gastric antrum cancer. It can significantly improve the life quality, extend the survival period, and improve the survival rate in patients with late gastric antrum cancer, which may be due to the up-regulation of the immune regulating factors such as IL-2, TNF-alpha, IFN-gamma and down-regulation of the immune inhibitory factor sIL-2R.

Objective: To compare tea polysaccharides(TPS) characteristics and their role in scavenging free radicals and reducing blood glucose(BG) in diabetic mice(DM). Methods: TPS was extracted from green,Oolong and black tea which were made from the same fresh leaves from Hubei,Fujian and Yunnan. Then the recovery rate of TPS, contents of neutral sugar, uronic acid and protein were analysed, and scavenging rate of -2Oand 稯H in vitro and hypoglycemic effect were also determined. Results: 1. The yield and contents of neutral sugar, uronic acid and protein of green tea TPS were the highest, and those of black tea TPS were the lowest. Oolong tea TPS acted the best in scavenging-2O and 稯H . 2. The hypoglycemic effect of TPS from Hubei tea was the best . The effect of TPS extracted from semi-fermented Oolong tea and fermented black tea was better than that of non-fermented green tea. 3. There were obvious differences in yield, free radical scavenging rate and effect of reducing BG among TPS extracted from tea in different regions. TPS extracted from Fujian tea had the best effect in reducing BG,but that from Yunnan tea had not. Conclusion: There was remarkable effect of region and process on physico-chemical characteristics,effect of scavenging radical and reducing blood sugar TSP.

In order to construct an integrated DNA barcoding database for identifying Chinese animal medicine, the authors and their cooperators have completed a lot of researches for identifying Chinese animal medicines using DNA barcoding technology. Sequences from GenBank have been analyzed simultaneously. Three different methods, BLAST, barcoding gap and Tree building, have been used to confirm the reliabilities of barcode records in the database. The integrated DNA barcoding database for identifying Chinese animal medicine has been constructed using three different parts: specimen, sequence and literature information. This database contained about 800 animal medicines and the adulterants and closely related species. Unknown specimens can be identified by pasting their sequence record into the window on the ID page of species identification system for traditional Chinese medicine (www. tcmbarcode. cn). The integrated DNA barcoding database for identifying Chinese animal medicine is significantly important for animal species identification, rare and endangered species conservation and sustainable utilization of animal resources.

OBJECTIVETo investigate whether myocardial bridging (MB) is independently associated with coronary atherosclerosis proximal to MB in the left anterior descending coronary artery (LAD) identified by computed tomographic coronary angiography (CCTA).

METHODSFrom March 2011 to December 2012, patients (n=9 862) with suspected coronary disease underwent CCTA using dual-source CT scanner. The baseline clinical characteristics (age, gender, smoking history, presence of hypertension, dyslipidemia, diabetes mellitus, family history of heart attack, and body mass index) and the results of CCTA were reviewed. Two radiologists evaluated the coronary artery for MB and coronary atherosclerosis stenosis (CAS) in LAD and made a diagnosis by consensus. Significant independent risk factors for CAS were investigated by multivariate logistic regression analysis.

RESULTSA total of 3 182 (32.3%) cases of MB and 3 359 cases of CAS of LAD were identified. No patient with CAS in the tunneled segment was found. The mean length of bridges and the mean thickness of the overlying myocardium was (17.3±5.2) mm and (1.2±0.9) mm, respectively. There were 1658 MB cases in 3 359 cases of LAD stenosis and 1 524 MB cases in 6 503 cases of no LAD stenosis (χ(2)=681.12, P<0.05). Logistic regression analysis showed that MB in the LAD were significantly associated with CAS in the proximal LAD (OR=3.07, 95%CI=2.81-3.37, P<0.001), and after final adjustment for age, gender, body mass index, family history of heart attack, smoking, hypertension, dyslipidemia, diabetes mellitus, and resting heart rate (OR=2.86, 95% CI=2.60-3.16, P < 0.001).

CONCLUSIONMB in the LAD is independently associated with CAS in the proximal segment to MB.

OBJECTIVETo explore the clinical and laboratory features and the prognosis of juvenile dermatomyositis (JDM) complicated with interstitial lung disease (ILD).

METHODData of 39 cases of JDM complicated with ILD hospitalized in Beijing Children's Hospital from January 2005 to December 2011 were collected. The clinical features, laboratory data and prognosis of these children were analyzed.

RESULTOf the 39 cases studied, 16 were boys, and 23 girls. The average age of onset was 5.6 years, and 61.5% of the patients' age of onset (24 cases) was under 6 years. Rashes (17 cases, 43.6%), simultaneous eruption of rashes and muscle weakness (14 cases, 35.9%), fever (4 cases, 10.1%), or muscle weakness (3 cases, 7.7%) were common initial symptoms of the disease. Only 51.3% of the patients (20 cases) had the symptoms of respiratory system, but (24 cases) 61.5% were complicated with that of the gastrointestinal system; (27 cases) 69.2% had at the same time electrocardiographic and echocardiographic abnormalities. The chest high resolution computed tomography (HRCT) showed cord or band-like shadows in their lungs of more than half of the cases (25 cases, 64.1%), and other changes included ground glass-like shadow (10 cases, 25.6%), net and lineation-like shadow (9 cases, 23.1%), nodular change (5 cases, 12.8%). The patients complicated with lung essential infiltration accounted for as high as 71.8% (28 cases). These imaging changes were largely seen on both dorsal sides of their lungs. Severe patients also had mediastinal emphysema, pneumothorax, pneumorrhagia or aerodermectasia. Twenty-four patients underwent pulmonary function examination, and 62.5% of the patients' pulmonary function (15 cases) was abnormal. The fatality rate of the cases studied was 10.1%.

CONCLUSIONThe imaging changes of patients suffering from JDM with ILD were often more severe as compared to the clinical symptoms, and were often complicated with damages to other systems and organs. The prognosis of those patients was poorer than others. Patients with JDM especially at a younger age of onset and with various organ damages should be examined with chest HRCT examinations as early as possible.

OBJECTIVETo study the survival rate and secretory function of islet cells in rats under condition of three-dimensional microgravity.

METHODSIsolated islet cells were assigned to flask-cultured or bioreactor-cultured. Survival rate of islets cultured for days 3, 7, 14 in stationary flasks or microgravity bioreactors was measured by AO-PI double-staining. Cultured islets were identified by dithizone (DTZ) staining, and insulin contents of different culture liquids were measured by radioimmunoassay.

RESULTSPancreatic islets stained nacarat with DTZ were easily visualized. When islet cells were cultured for 7 days and 14 days, survival rate of bioreactor-cultured islets was (0.9000 +/- 0.0107)% and 0.8038% +/- 0.0092% and higher than flask-cultured islets (P < 0.01). Insulin level of bioreactor-cultured islets is (70.875 +/- 0.31) m micro /L on the cultured 7 days while flask-cultured islets is (41.246 +/- 0.35) m micro /L. There was statistically significant difference of insulin production between the two groups (P < 0.01). Bioreactor-cultured islet contents were higher than flask-cultured on the cultured 14, 21 and 30 days (P < 0.01).

CONCLUSIONSIslet cells survival rate and secretory function revealed that bioreactor-cultured islets functioned better compared with flask-cultured islets.
