An aluminium disc was put inarotating megnetic field.Due to mutual effect of eddy current in the disc and the megnetic field,the disc was rotated and drove a piston vacuum pump and in turn negative pressure was generated,This is the principle of our decompressor.The suction of the decompressot can be ad- justed when necessarty and displayed by a negtive pressure indicator.The auto- matic stop and alarm system have been designed.When the bottle is full the system will stop the pump and give an alarm immediately in ortder to protect the mecha- nismic parts from being damaged.

Objective To analyze the clinical characteristics in elderly onset rheumatoid arthritis(RA) patients combined with interstitial lung disease(ILD).Methods Four hundred and four cases of elderly onset RA patients were summarized.They were divided into two groups according to whether combined with ILD.Its clinical manifestations,laboratory examinations and combined diseases were analyzed.Results (1)Male elderly patients with onset of RA were more likely to occur ILD than female(χ2=6.251,P=0.012).There was no significant difference in duration analysis of two groups(t=1.750,P=0.081).(2)The elderly onset patients in RA with knee pain were more likely to happen ILD(χ2=7.048,P=0.008),the difference was significant.And there was no significantly statistical difference in the shoulder joint pain(χ2=0.028,P=0.866),elbow pain(χ2=0.022,P=0.882),hand joint pain(χ2=2.041,P=0.153),hip pain(χ2=0.129,P=0.720),joint deformities(χ2=0.013,P=0.908),morning stiffness(χ2=0.000,P=0.984) and joints rheumatoid nodules(χ2=0.349,P=0.555) of two groups.(3)The elderly onset RA patients with a high level of serum RF were more likely to happen ILD(t=3.325,P=0.001),the difference was significant.And there was no significantly statistical difference in serum ANA antibodies(χ2=0.004,P=0.948),anti SSA(χ2=0.718,P=0.397),SSB antibody(χ2=0.638,P=0.424),AKA antibody(χ2=0.949,P=0.330),CCP antibody(χ2=0.500,P=0.479) and the level of ESR(t=0.582,P=0.561),CRP(t=0.381,P=0.703) and PLT(t=-1.246,P=0.213).(4)The elderly onset RA patients with ILD were more likely to appear osteoporosis(χ2=7.467,P=0.006),the difference was significant.And there was no significantly statistical difference in the occurrence of high blood pressure(χ2=0.403,P=0.526) and diabetes(χ2=0.180,P=0.671) in the two groups.Conclusion Male patients,the elderly onset RA patients with knee pain and associated with high level of serum RF more often occur with ILD.And the elderly onset RA patients with ILD are more likely to appear osteoporosis.

Objective To evaluate the curative methods of periampullary diverticula(PAD) complicated with biliopancreatic disease.Methods The clinical data of 32 cases of PAD complicated with biliopancreatic disease treated by surgical or endoscopic measures were retrospectively analyzed.Results Of the 32 cases,16 cases were treated with gastroectomy and Roux-en-Y gastrojejunostomy,and 8 with gastroectomy and Billroth Ⅱ gastrojejunostomy,8 with endoscopic sphincterotomy (EST).Postoperative complication occured in 4 cases,but no operative death.Twenty-seven cases were followed up for 5 months-8 years, and the results were excellent in 20 cases, good in 7 cases.Conclusions Gastroectomy and Roux-en-Y gastrojejunostomy is a better surgical method for PAD complicated with biliopancreatic disease.EST has become a new effective measure to deal with the diseases;It will be safe to use the first method for patients with intradiverticular papilla if it treated by EST.

Objective To explore the clinical significance of dyslipidemia in patients with systemic lupus erythematosus (SLE).Methods By independent-samples t test,serum lipid level was compared between 326 SLE patients and 300 healthy controls.The total cholesterol (TC),triglyceride (TG),lowdensity lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels were partially compared in subgroups of SLE patients.The correlation of serum TC,TG,LDL-C and HDL-C with clinical manifestations and laboratory findings in SLE was analyzed by Pearson or Spearman correlation analysis.Results ①The serum levels of TC [(3.8±1.5) mmol/L],TG [(2.1±1.6) mmol/L] and LDL-C [(2.1±0.9) mmol/L] were significantly higher in SLE group than those of the control group [(3.4±0.6),(0.8±0.4),(1.9± 0.5) mmol/L],and the serum level of HDL-C [(1.2±0.9) mmol/L] was significantly lower in SLE group than that of the control group [(2.0±0.5) mmolFL] (t=4.953,P=0.000; t=14.569,P=0.000; t=3.204,P=0.001; t=-14.335,P=0.000].② The serum levels of TC [(4.0± 1.7) mmol/L],TG [(2.5± 1.7) mmol/L] and LDL-C [(2.2±1.0) mmol/L] were significantly higher in LN group than those of the non-LN group [(3.6±1.0),(1.6± 1.0),(1.9±0.7) mmol/L; t=2.646,P=0.009; t=6.292,P=0.000; t=3.261,P=0.001].③ The serum level of TG [(2.2±1.6) vs (1.8±1.4) mmol/L] was significantly higher in SLE patients with hypocomplementemia than that of the normal ones (t =2.098,P=0.038).The serum level of HDL-C [(1.1 ±0.4) vs (1.6± 1.7) mmol/L] was significantly lower in SLE patients with hypocomplementemia than that of the normal ones (t=-2.375,P=0.020).④ The serum level of TG [(2.3±1.7) vs (2.0±1.4) mmol/L] was significantly higher in anti-dsDNA antibody positive patients than that of negative ones (t=1.989,P=0.048).The serum level of HDL-C [(1.5± 0.4) vs (1.4±1.2) mmol/L] was significantly lower in anti-dsDNA antibody positive patients than that of negative ones (t=-2.979,P=0.003).⑤ The lipid level was correlated with the clinical manifestations and laboratory findings in SLE patients.Conclusion Dyslipidemia exists in patients with SLE and has close correlation with LN,hypocomplementemia and positive anti-dsDNA antibody.

To construct a library of mouse single chain variable fragment (scFv) antibody against ofloxacin using phage display and recombinant antibody technique, specific anti-ofloxacin scFv was screened and 3D structure was homology modeling. Total RNA was extracted from hybridoma cell of ofloxacin mAb, and was used to amplify VH and VL gene by RT-PCR using random primer. Then they were linked by a DNA linker encoding (G1y4 Ser) 3 as VH-linker-VL sequence forming scFv by SOE(splicing by overlap extension) PCR. These fragments were inserted into phage T7 after double digestion and transformed with host bacteria BLT5403. 3 ×105 pfu / ml single chain antibody phage libraries were successfully constructed. Four positive phage scFv clones were screened by direct competitive ELISA after four times of enriched procedure in the order of adsorption-elution-amplificatio, 3D structure of specific scFv was homology modeling finally. This research lays a foundation for further massive expression of anti-ofloxacin scFv.

Objective To evaluate the efficacy and safety of induction concurrent chemoradiation therapy with weekly docetaxel and cisplatin(DP) for stage Ⅲ A-N2 lung cancer.Methods Eighteen patients diagnosed of stage Ⅲ A-N2 NSCLC in our center were enrolled from March,2011 to November,2013.The induction regimen consisted of 5 cycles of docetaxel(20 mg/m2) and cisplatin(20 mg/m2) administered intravenously on days 1,8,15,22 and 29 with concurrent thoracic radiotherapy in fractions of 1.8Gy,to a total dose of 45Gy.Patients proceeded to surgery,if no progressive disease occurred,followed by adjuvant chemotherapy with DP strategy.Results Eighteen patients were enrolled and 12 underwent surgery.The tumor response for the induction therapy was 1 CR,10 PRs,6 SDs and 1 PD.Five of 18 patients presented with level 3 or above adverse effects,among which were 2 neutropenia,1 liver toxicity,1 anemia and 1 lymph node infection.The median operation time was 290 min,intraoperative blood loss was 350 ml,length for postoperative drainage was 5 d,and time to discharge was 7 d.The mediastinal lymphnodedownstaging rate was 50％ (3 pN0 cases and 3 pN1 ones),92％ of the operated patients reached complete resection.One-year survival was 75.9％ and 1-year progression free survival was 49.2％.Conclusion Weekly docetaxel and cisplatin strategy in induction concurrent chemoradiotherapy for stage Ⅲ A-N2 NSCLC patients has been validated to be safe and effective.

Objective To investigate the effects of emodin on the triglyceride metabolism and oxidative stress in steatosis in HepG2 cells and possible underlying mechanisms.Methods The appropriate concentration of emodin on HepG2 cells were detected by methyl thiazolyl tetrazolium (MTT) assay.HepG2 cells were induced to fat overaccumulation by 1 mmol/L free fatty acids (FFA) (oleate∶ palmitate =2∶1).The model group exposed to 10 μmol/L,20 μmol/L,40 μmol/L emodin.The intracellular lipid accumulation was documented by Oil Red O staining and the content of triglyceride and total cholesterol was observed.Reactive oxygen species (ROS) was determined by flow cytometry.Western blotting was performed to analyze the protein levels of adenosine monophosphate-activated protein kinase (AMPK),phosphorylated AMPK,and sterol regulatory element-binding protein 1 (SREBP-1).Results Emodin reduced lipid accumulation and triglycerides (TG) content (P ＜ 0.05).At the same time,it significantly reduced ROS production (P ＜ 0.05).Moreover,the levels of AMPK and p-AMPK protein were significantly upregulated,and SREBP-1 protein was significantly downregulated with the treatment of emodin (P ＜ 0.01).Conclusions This study has demonstrated that emodin can reduce fatty degeneration induced by FFAs in hepatocytes,and this effect may be partially mediated by the AMPK/SREBP-1 pathway.
