Objective To study the clinical curative effect of the recombinant human granulocyte-macro-phage colony-stimulating factor ( rhGM -CSF) joint R-CHOP regimen in the treatment of diffuse large B cell lymphoma (DLBCL).Methods 72 hospitalized patients with DLBCL were chosen from January 2014 to January 2015.The patients were randomly divided into joint CHOP rituxan group ( R-CHOP group,36 cases) and the joint treatment group (36 cases) .The R-CHOP group was treated by R-CHOP regimen,the joint group was given rhGM-CSF on the basis of R-CHOP treatment.Before chemotherapy and 15 days,1 month,3 months after chemotherapy, the peripheral blood was collected,and the monocytes were separated,flow cytometry was used to count HLA-DR, CD197 marked M1 cells and CD68,CDl63 marked M2 cells.4 months after chemotherapy,the curative effect was evaluated.Results 4 months after treatment,the ORR of joint group (91.67%) was significantly higher than that of R-CHOP group (75.00%),and the difference was statistically significant (χ2 =4.372,P<0.05).After treatment, the adverse reactions of joint group,the liver function injuryⅠ-Ⅱlevel 8.33%,Ⅲ-Ⅳlevel 0.00%;White blood cells reduceⅠ-Ⅱlevel 25.00%,Ⅲ-Ⅳ level 5.56%;Thrombocytopenia Ⅰ-Ⅱ level 19.44%,Ⅲ-Ⅳ level;8.33%;Nausea and vomitingⅠ-Ⅱ level 8.33%,Ⅲ-Ⅳ level 0.00%.The adverse reactions after treatment of R-CHOP group,the liver function injury Ⅰ-Ⅱ level 13.89%,grade Ⅲ-Ⅳ2.78%;White blood cells reduceⅠ-Ⅱlevel 36.11%,Ⅲ-Ⅳlevel 11.11%;ThrombocytopeniaⅠ-Ⅱlevel 33.33%,Ⅲ-Ⅳlevel 2.78%;Nau-sea and vomitingⅠ-Ⅱ level 13.89%,Ⅲ-Ⅳ level 0.00%.The increased ratio of TAM quantity in combined treatment group (63.89%) was significantly more than R-CHOP group (38.89%),the difference was statistically significant (χ2 =7.938,P <0.05).In joint group,the positive expression rates of CD68 (46.11%),IL -6 (44.44%),IL-8 (58.33%) were significantly higher than those of R-CHOP group[CD68 (13.89%),IL-6 (19.44%),IL-8 (38.89%)],the differences were statistically significant (χ2 =3.278,3.278,4.489,all P<0.05).Conclusion R-CHOP joint rhGM -CSF has better curative effect than R-CHOP plan and less adverse reaction,and under the induction of rhGM -CSF,mononuclear cells can develop into M1 macrophages,in DLBCL microenvironment,to induce TAM to M1 M2 type in reverse polarization,improve the microenvironment of DLBCL and provide chance for cure of DLBCL.

OBJECTIVETo investigate the effect of Antrodia cinnamomea on gene expression related to aortal endothelial injury of rats with hyperlipidemia.

METHODFifty SD rats were randomly divided into five groups: the normal control group (NG), the model group (MG), the antrodia cinnamomea groups of low, middle and high doses (AC-LG, AC-MG, AC-HG, 250, 500, 1 000 mg x kg(-1)). The rats were fed with high-fat diets to establish the hyperlipidemia model. After the drug administration for 10 weeks, their serum lipid, SOD, MDA and ox-LDL, LOX-1, P38 MAPK and NF-kappaB mRNA and protein expression were respectively determined, and the aortal endothelial injury was observed under electron microscope.

RESULTIn the model group, the contents of TC, TG and LDL-C significant increased (P < 0.01), whereas the content of HDL-C significant decreased (P < 0.01). Compared with the model group, both the AC-M group and the AC-H group showed reduction in endothelial injury and significant decrease in the content of TC, TG and LDL-C (P < 0.05 or P < 0.01). The content of HDL-C increased, but with no significant difference. SOD activity in serum remarkably increased (P < 0.05 or P < 0.01), MDA and ox-LDL levels dramatically decreased (P < 0.05 or P < 0.01).

CONCLUSIONA. cinnamomea can alleviate endothelial lipid injury by inhibiting the expressions of LOX-1, P38MAPK and NF-kappaB in aorta and better protect aortal endothelial cells from oxidative lipid injury.

With new acupuncture and moxibustion as the study object, based on the basic composition of acupuncture-moxibustion theory, from 3 aspects of meridian-acupoint theory, acupuncture-moxibustion method theory and acupuncture-moxibustion treatment theory, under the background of western medicine, ZHU Lian's different opinions on theory and method of acupuncture and moxibustion were discussed. It was believed by ZHU Lian that the distribution of 14-meridians was approximately identical to that of nerves, so with modern neuroanatomy knowledge to understand the meaning of acupoint; the acupuncture function could be explained from the angle of neurophysiology. Clinical diagnosis and treatment method could be established by modern classification methods of diseases. ZHU Lian's cognition that was different from traditional theory and method of acupuncture and moxibustion was combined with updated physiology and anatomy knowledge at that time, and was involved with Pavlov's advanced nerve theory, so she firstly put forward the opinion that acupuncture therapy can't work without the involvement of cerebral cortex.

Objective To evaluate the diagnostic accuracy of contrast-enhanced MR angiography (CE MRA) in infrapopliteal occlusive diseases of diabetic patients.Methods A total of 105 patients with known diabetes and peripheral vascular occlusive disease who underwent both CE MRA and DSA examnations were included in this study.They had no obvious stenosis or with stenosis of less than 75％ in iliac,femoral,and popliteal arteries.Every infra-popliteal artery was anatomically divided into 9 vascular segments as tibiofibular trunk artery,proximal and distal anterior tibial artery,proximal and distal posterior tibial artery,proximal and distal peroneal artery,plantar and dorsalis pedis artery.There were 945 segments.The arterial stenosis was accessed with CE MRA and DSA respectively.The segments were scored in 5 categories as＜30％,≥30％ and＜50％,≥50％ and＜75％,≥75％ and＜100％,and 100％ according to stenostic degrees.The Kappa test was used to compare the diagnostic consistency of CE MRA and DSA.Taken DSA as a gold standard for reference,ROC curve was drawn to calculate the diagnostic accuracy of CE MRA in diagnosis of lower limb arterial disease.Results The ratio of statistically valid segments for both CE MRA and DSA were 97.7％ (923/945) in 945 vessel segments of 105 patients,and 390 of 923 arterial segments were both indicated as occlusion by CE MRA and DSA.The diagnostic consistency for the segments was listed in the decreasing order as follows:proximal peroneal artery,proximal posterior tibial artery,distal posterior tibial artery,proximal anterior tibial artery,distal anterior tibial artery,tibiofibular trunk artery,dorsalis pedis artery,plantar artery,distal peroneal artery,and corresponding Kappa values were 0.88,0.86,0.84,0.84,0.81,0.77,0.75,0.75 and 0.73,P＜ 0.05.The AUC(area under ROC curve) of CE MRA was 0.893 with 95％ confidence interval of 0.882 to 0.904.Conclusion CE MRA is an accurate imaging modality in the diagnosis of infrapopliteal occlusive disease s for diabetes.

Objective:To investigate the effects of Nano-chitosan rhBMP-2 Gel(NCS/BMP-2 Gel)on the repair of mandibular de-fect.Methods:NCS/BMP-2 Gel and NCS Gel were prepared and respectively injected into the subcutaneous space on both sides of dorsum of 9 rats.3 rats were respectively sacrificed 10,20 and 30 d after injection.The subcutaneous nodules were histologicaly ex-amined.Mandibular defect was made in 54 SD rats and the rats were divided randomly and into 3 groups(n=18):NCS/BMP-2 Gel was implanted into the defects in group 1,NCS Gel in group 2,no injection in group 3.Animals were sacrificed 3,6 and 9 weeks after transplantation.X-ray examination,pathologic observation were conducted.Results:Subcutaneous nodules were found in both sides of the rat dorsum.The residual mandibular defect area in study group 1 was apparently smaller than that in group 2 and 3(P<0.05). More new bone formation was observed in the gel injected area in group 1 than in group 2 and 3.Conclusion:Nano-CS/BMP-2 Gel is biocompatible and can accelerate the healing of mandibular defect.

Purpose:To explore the preventive effect of hepatic arterial infusion (DDS) against recurrence of hepato- cellular carcinoma (HCC) after radical resection.Methods:From Jan,1996 to May,1998,287 patients of HCC after radical resection were randomly divided into four groups:intra-hepatic arterial infusion(97),intra-portal vein(80),intra-hepatic artery and portal vein (60),control (50).All patients received chemotherapy for two years and observed for postoperative recurrence of HCC.Results:The postoperative recurrence rate of HCC with intra-hepatic arterial infusion was significantly lower than that of intra-portal vein (P0.05).The 1～、2～ and 3～year survival rate of intra-hepatic arterial infusion was significantly higher than any of the other groups.Conclusions:Intra-hepatic arterial infusion (DDS) through gastro-duodenal artery can effectively pro- long the postoperative survival and decrease the post-operative recurrence rate of HCC.The preventive method of DDS through gastro-duodenal artery was safer and effective.

Aim To investigate the activation of prote-ase-activated receptor 2 ( PAR2 ) in regulation of the expression of epidermal growth factor receptor ( EGFR) and apoptosis of lung cancer ( LC) cells. Methods LC cells A549 and its EGFR-silenced counterpart were incubated in the medium added with tryptase. Quanti-tative RT-PCR and Western blotting were used to de-tect the expression of EGFR in A 5 4 9 cells . The apop-tosis and Bax/Bcl-xL of cells were also recorded. Re-sults Treating A549 cells with tryptase in the culture for 48 hrs resulted in a marked increase in the expres-sion of EGFR in A549 cells. Marked decreases in a tryptase dose-dependent manner in apoptotic A549 cells were detected in the presence of tryptase. Expo-sure to tryptase markedly decreased the levels of Bax and increased the levels of Bcl-xL in A549 cells, which were not shown in EGFR-deficient A549 cells. Conclusion Tryptase can increase the expression of EGFR in LC cell line, A549 cells, which protects A549 cells from apoptosis, increases Bcl-xL, and sup-presses Bax in A549 cells.

BACKGROUND:Cel membrane microparticles CD31 and CD54 lead to microvascular injury in the femoral head by mediating vascular inflammatory response, promoting blood clotting, affecting vasomotion and promoting vascular endothelial injury. Studies have verified that membrane particles play an important role in steroid-induced necrosis of the femoral head, but there is no studies concerning relationship between microparticles and alcohol-induced avascular necrosis of femoral head. METHODS/DESIGN:This is a randomized control ed animal study. Healthy male Wistar rats wil be randomly assigned to two groups. In the model group, rats wil be intragastrical y administered hard liquor for 6 consecutive months to prepare models of alcohol-induced avascular necrosis of the femoral head. Blank controls wil be intragastrical y given an equal volume of physiological saline. In 1-6 months of intervention, six rats wil be randomly selected from each group every month. Blood wil be col ected separately. Flow cytometry wil be used to detect serum cel membrane particles CD31, CD54 levels. Bilateral femoral head wil be fixed, decalcified, embedded in wax, and then sections. After hematoxylin-eosin staining, empty bone lacuna wil be quantified under a light microscope to identify femoral head necrosis. Verhoff’s staining and MSB microthrombosis staining wil be used to observe microvascular injury and microvascular thrombosis in the femoral head, and to analyze the correlation of CD31 and CD54 levels with femoral head necrosis, vascular endothelial injury and microvascular thrombosis. DISCUSSION:This study wil investigate the effects of CD31 and CD54 on alcohol-induced avascular necrosis of the femoral head, explore the pathogenesis of alcohol-induced avascular necrosis of the femoral head, provide a new theoretical basis for early diagnosis and early treatment, and may provide a new target for its treatment. ETHICS APPROVAL:The protocol has been approved by the Animal Experimental Ethics Committee of Inner Mongolia Medical University (approval number YKD2016154). Experimental procedures and materials of rats wil be in accordance with the Guide for the Care and Use of Laboratory Animals, which is consistent with the guide of National Institutes of Health.
