Objective To investigate the effect of endoplasmic reticulum stress in hyperlipidemia rats with acute pancreatitis(AP).Methods Forty-eight SD rats were divided into AP group(n=18,in- duced by injection of 40?tg/kg caerulein in normal rats twice with 2 hrs interval),normal control(n=6), byperlipidemia group(n=6,fed with a high-fat diet for 8 weeks)and hyperlipidemia AP group(n=18,in- duced by injection of 40?g/kg caerulein in hyperlipidemia rats twice with 2 hrs interval).The rats were sacrificed at 9,12,24 hrs(6 of each),respectively.Serum level of amylase was tested and the pathologi- cal changes of the pancreatic tissues were observed.The index of pancreatic apoptosis was assessed by TUNEL method.The expression of GRP78/Bip(glucose regulated protein)protein was determined by immunochemistry,the endoplasmic reticulum stress related molecules of XBP-1 splicing(X box binding protein),CHOP/GADD153(C/EBP-homologous protein or growth arrest and DNA-damage-inducible gene 153),caspase-12 were analyzed by RT-PCR.The dynamic expressions of GRP78/Bip and caspase- 12 were determine,d by Western blot.Results Artier 8 weeks of fat diet in hyperlipidemia rats,the ser- um levels of triglyceride[(0.99?0.38)mmol/L]and cholesterol[(3.17?0.18)mmol/L] were signifi- cantly increased(P

0.05].In 48 patients without lymph node metastasis,there was no significant difference between the OPN-positive and OPN-negative patients in survival times.Multivariate analysis revealed that survival times was associated with patients′sex(P=0.032)and TNM stage(P

Objective A recombinant adenoviral vector containing mIL-18BP and mIL-4 fusion gene(AdmIL-18BP/mIL-4) was constructed and used to investigate the role of mIL-18BP and mIL-4 in medula-ring the expressions of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthetase (iNOS) and their inducing products PGE2, NO in murine collagen-induced arthritis. Methods Male DBA-1/BOM mice were used in this study. Mice with CIA were intra-articularly injected with 107 pfu/6μl of AdmIL-18BP/mIL-4.Intra-articular injections of AdLacZ or PBS were used as controls. The mRNA expression of COX-2, iNOS in synovial tissue was analyzed by semi-quantitative RT-PCR. Expression of COX-2 and iNOS protein was estimated by Western blot method. The production of PGE2 and NO in synovia was detected by competitive ELISA and enzyme reduction of nitrate. Results The expression of COX-2, iNOS mRNA in routine synovial tissue of AdmIL-18BP/mIL-4 treatment group was significantly lower than that of AdLacZ group (0.15 vs 0.42,P<0.01 ; 0.05 vs 0.77, P<0.01) and PBS group (0.15 vs 0.65, P<0.01; 0.05 vs 0.64, P<0.01 ). And the protein expression of COX-2, iNOS from AdmIL-18BP/mIL-4 treatment group was also obviously lower than that of AdLacZ group (0.08 vs 0.92, P<0.01; 0.11 vs 1.00, P<0.01) and PBS group (0.08 vs 0.77, P<0.01; 0.11 vs 0.84, P<0.01 ). The PGE2 and NO production in synovia of AdmIL-18BP/mIL-4 treatment group was significantly lower than that of AdLacZ group [(0.68x0.06) vs (2.58±0.21)ng/mL, P<0.01; (23.4+2.5) vs (60.0±11.3)μmol/L, P<0.01 ] and PBS group [(0.68±0.06) vs (2.57±0.20)ng/mL, P<0.01; (23.4+2.5) vs (60.3±13.4)μmol/L, P<0.01]. Conclusion These data indicat that local over-expre-ssion of mIL-18BP and mIL-4 can down-regulate COX-2, iNOS and their induced product PGE2, NO in CIA mice. The combination treatment with mIL-18BP and mIL-4 is a promising therapeutic target for RA.

OBJECTIVETo observe differences of therapeutic effects among acupuncture bloodletting, penicillin and acupuncture bloodletting combined with penicillin for children acute tonsillitis and providea better treatment method in cli nic.

METHODSSeventy-five mild cases were selected into section of mild symptoms while seventy-five severe cases were selected into section of severe symptoms. Cases in the two sections then were divided into, an acupuncture bloodletting group, a penicillin group and a comprehensive group by random digital table method separately, 25 cases in each one. Qu-chi (LI 11), Hegu (LI 4), Dazhui (GV 14), Shaoshang (LU 11) and Erjian (EX 11) were selected in the acupuncture bloodletting group, intravenous injection of penicillin sodium was applied in the penicillin group and acupuncture bloodletting combined with penicillin was applied in the comprehensive group. Efficacy assessment was conducted after 3 days in the section of mild symptoms and after 5 days in the section of severe symptoms.

RESULTSFor the section of mild symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group and 92.0% (23/25) in the acupuncture bloodletting group, which were both superior to 68. 0% (17/25) in the penicillin group (P<0.05), but no statistical significance was seen between the comprehensive group and acupuncture bloodletting group (P>0.05). For the section of severe symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group, which was obviously superior to 60.0% (15/25) in the acupuncture bloodletting group (P<0.01) and 68.0% (17/25) in the penicillin group (P<0. 05), and no statistical significance was seen between the acupuncture bloodletting group and penicillin group (P>0.05).

CONCLUSIONThe efficacy of acupuncture bloodletting combined with penicillin is little different from that of acupuncture bloodletting for treatment of children acute tonsillitis with mild accompanied symptoms, which were both superior to intravenous injection of penicillin sodium. For severe accompanied symptoms, the efficacy of acupuncture bloodletting combined with penicillin is obviously superior to acupuncture bloodletting and penicillin.

The naturally-occurring dipeptide carnosine (beta-alanyl-L-histidine) is found exclusively in animal tissues, such as brain and skeletal muscle tissues. Carnosine is a potent hydrophilic antioxidant, antiglycating agent, reactive oxygen species scavenger and pH-buffer. Recent reports suggest that carnosine has potential therapeutic applications in many diseases of central nervous system, such as Alzheimer's disease, Parkinson's disease and cerebral ischemic diseases. To investigate the relationship between carnosine and diseases of central nervous system, and to research and develop carnosine drugs will shed light on a new way for treatment of diseases of central nervous system.

The prevalence of inflammatory bowel disease (IBD) in China is increasing year by year, however, the efficacy and safety of commonly used therapeutic methods are limited.Granulocyte and monocyte adsorptive apheresis (GMA) is one of the effective methods for treatment of IBD used abroad, however, there is still lacking of such research in China.Aims: To investigate the efficacy and safety of GMA in IBD patients.Methods: A retrospective study was conducted in 21 cases of IBD patients [13 cases with ulcerative colitis (UC) and 8 with Crohn's disease (CD)] who accepted GMA treatment from May 2013 to July 2014 at the Shanghai Rui Jin Hospital.All the cases were poor responders to 5-aminosalycylic acid (5-ASA) or steroid-refractory.The clinical data were collected, and the clinical activity index (CAI), endoscopic activity index (EAI), laboratory parameters including serum albumin (Alb), hemoglobin (Hb), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), leukocyte count and percentage of neutrophils, as well as the adverse effects before and two weeks after the end of GMA treatment were analyzed.Results: After GMA treatment, both CAI and EAI were decreased significantly in UC and CD groups as compared with those before treatment (P all <0.05).Among laboratory parameters, Alb was increased in UC group and CRP was decreased in both UC and CD groups after treatment (P all <0.05).No significant differences were found in other laboratory parameters in both UC and CD groups before and after treatment (P all >0.05).The treatment was well tolerated with no severe adverse effects.Conclusions: GMA is safe and effective for ameliorating clinical symptoms, attenuating intestinal mucosal injury and controlling active inflammation in IBD patient that has not responded to 5-ASA or steroid treatment.Prospective clinical studies with large samples are needed to confirm these findings.

Mycoepoxydiene is a novel antitumor agent extracted from marine lignicolous fungi HLY-2, which is Diaporthe phaseolorum by molecule identification. The medium optimization for mycoepoxydiene by orthogonal design and the comparison of submerged fermentation and solid state fermentation were studied. The rusult is that the maximal yield of the compound is 543mg/L, which is 43 times compared to the customary half-seawater PD medium and 15 times to the best submerged condition. This optimum culture medium included potato 250g/L, seawater 300mL/L, glucose 30g/L, lactose 50g/L, KH_ 2 PO_ 4 0.65mmol/L and (NH_ 4 )_ 2 SO_ 4 1g/L in the solid state condition. Differentiation analysis between submerged and solid state fermentation, and antitumor activity of these ferment products were also studied. The antitumor activity of products of the optimum medium approached the pure compound.

ObjectiveTo explore the relationship between the status of vitamin A and the level of AntiHBs in infants.Methods One hundred and ninty eight infants met the criteria were recruited into an investigation through local vaccination service.Two milliter venous blood was drawn from each studied child,and the infants' feeding information of successive 72 hours was collected through the 24-hour dietary recall method and 2-day diet records method.The nutrients intakes were analyzed with a NCCW software for calculation.The concentration of serum vitamin A and Anti-HBs was analyzed by HPLC and ECLIA,respectively.The logarithm of anti-HBs concentrations was compared among sub-clinical vitamin A deficiency (87 cases ),suspicious subclinical vitamin A deficient group (51 cases )and normal group (60 cases )and the relationship between the logarithm of anti-HBs concentrations and vitamin A were analyzed.ResultsThere were only 19.7％ of children whose average daily intake of vitamin A reached the 80％ of recommended nutrient intakes(RNI).The incidence rate of vitamin A malnutrition was 67.2％.The serum Anti-HBs GMC was 402.8 U/L The positive rate was 98.0％.There were significant differences on Anti-HBs Ig GMC between Sub-clinical vitamin A deficiency (SVAD) group,suspicious SVAD group and normal group( F =15.88,P ＜ 0.001 ).The correlation coefficient between the level of serum vitamin A and Anti-HBs lg GMC was 0.441 ( P =0.01 ).ConclusionThe results show that the level of serum vitamin A may have influence on the maintenance of an effective anti-HBs level against hepatitis B virus.

Objective:To investigate the correlation between plasma homocysteine (Hcy) concentration and transient ischemic attack (TIA) and traditional vascular risk factors.Methods:The plasma Hcy concentrations of 112 patients with TIA and 62 controls were measured by fluorescenee polarization immunoassay.Hcy concentrations and related risk factors were analyzed.Results:The risk of TIA was increased significantly in plasma Hcy concentration 10.0 to 14.9 μmol/L group(OR=2.450,95% CI 1.091 to 5.502) and≥15.0 μmol/L group(OR=5.169,95% CI 2.096 to 12.746) compared with plasma Hcy concentration＜10.0 μmol/L group.Using TIA as the dependent wariable,various vascular risk factors (including plasma Hcy concentration) as the independent variable,logistic regression was analyzed.The result showed that the risk of TIA was increased significantly in plasma Hcy concentration＞10.0 μmol/L group compared with plasma Hcy concentration＜10.0 μmol/L group(OR=3.150,95% CI 1.380 to 7.192).Conclusions:Plasma Hcy concentration is an independent risk factor for TIA.
