Objective To examine the expression of macrophage migration inhibitory factor(MIF)in lung tissues of rats with experimental pulmonary fibrosis and to discuss its effects on pulmonary fibrosis.Methods36 male SD rats were randomly divided into two groups:the pulmonary fibrosis group and the control group.Rat pulmonary fibrosis was induced by an intratracheal injection of bleomycin.The following tests were undedaken: HE and Masson staining of lung section,immunohistochemical staining of protein of MIF in the lung,RT-PCR of MIFmRNA in the lung.ResultsCompared with the control group,the mRNA and protein expression of lung MIF on day 7 to 28 in pulmonary fibrosis increased and reached the peak on day 14 after an intratracheal injection of bleomycin(P

Objective To explore the clinical significance of hydrogen sulfide(H2S)and heme oxygenase-1(HO-1)on pulmonary hypertension(PH),by detecting their levels of patients with congenital heart disease(CHD).Methods Forty-eight patients with CHD who had left-to-right shunt were selected randomly from cardiac surgery in the Fourth Hospital of Hebei Medical University.Forty-eight patients were performed successfully on radical operation under complex intravenous anesthesia,and they were divided 3 groups according to pulmonary artery systolic pressure(PASP)detected by doppler echocardiography before operation:no PH group(PASP0.05).Conclusions H2S plays an important role in the formation of PH and restructure.There is no correlation between PASP and HO-1 activities in serum,but HO-1 may be play an indirect action in the formation of PH and restructure.Measuring the levels of H2S may be a reliable method to follow the change of pulmonary pressure and worsening of PH.

Objective:To investigate the inductive function of tumor necrosis factor(TNF)-? to dentritic cell(DC) and its effect on erythroid hematopoiesis.Methods:Human CD34~+ cells was separated and purified by MACS method.With the existence of stem cell factor(SCF),interleukin-3(IL-3) and erythropoietin(EPO),CD34~+ cells were cultured together with TNF-? through external fluid.The expanding times of cells and their superficial markings were analysed by flow cytometry.Meanwhile,the morphological transformation of expanding cells was observed by microscope.Results:TNF-? could inhibit the development of glycophorin A(GPA;a specific erythroid marker) positive cells,while stimulates the growth of those GPA negative of non-erythroid cells.These cells usually possess the morphological characteristic of DCs and express phenotypical markers of DCs accordingly.Those erythroid progenitor cells which contact directly with DCs appear to have the change of cellular apoptosis.Conclusion:The inhibition of TNF-? to erythroid hematopoiesis is probably related to the induction of DCs proliferation.The possible reason for cellular apoptosis of erythoid progenitor cells may be their direct contact with DCs.

HCV-related decompensated cirrhos,hypersplenism,thrombocytopenia,which not only affect the standard antiviral therapy,fail to achieve the sustained virological response(SVR),but also increase the risk of infection and bleeding.The only successful option is liver transplantation (LT),but the recurrence of HCV after LT remains to be resolved.The patients of HCV genotype 2 are suitable for splenectomy and antiviral therapy following splenectomy,which can achieved a higher SVR and reversed cirrhosis.As an effective alternative to splenectomy,the partial splenic embolization (PSE) can improve the changes of portal hemodynamics and reduce the sequelae of portal hypertension.The appearance of direct antiviral drugs (DAAs)has bring hope for those with decompensated cirrhos and whom IFN is contraindicated or tolerated poorly,those who are waiting for LT or with recurrence of hepatitis C after LT.The treatment of patients with decompensated cirrhos is as follows.

A new teaching reform project in experiment of Human Parasitology is performed by improving experiment content and adopting a new teaching method.The project elucidates that teaching reform in experiment can enhance students'abilities in the experiment,self-teaching and problem-solving and problem-analyzing,and creative ability.

Objective To assess the efficacy and safety of leflunomide in active ankylosing spondylitis.Methods Totally 62 cases of active ankylosing spondylitis were included,and divided randomly into leflunomide group(n=26)and methotrexate group(n=36).The patients in leflunomide group received an oral leflunomide loading dose of 50 mg or 40 mg once daily for the first 3 days followed by a maintenance dose of 50 mg or 40 mg once weekly,according to whether the bodyweight was more than 50 kg or less than 50 kg,respectively.The patients in methotrexate group were prescribed oral methotrexate 5 mg once in the first week,10 mg once in the second week,15 mg once in the third week and thereafter weekly.Sulfasalazine was prescribed 0.75 three times daily in both groups.The Bath Ankylosing Spondylitis Disease Activity Index(BASDAI)and The Bath Ankylosing Spondylitis Metrology Index(BASIM)scoring instruments were used to assess the responsiveness to leflunomide and methotrexate at entry,three months,six months,twelve months and eighteen months after treatment,respectively.Laboratory data including peripheral blood counts(WBC,HGB,RBC),erythrocyte sedimentation rates(ESR),liver enzymes,serum creatinine,urinary sediments were detected at the same time.Sacroiliac joints CT scan and other involved joints x-ray radiograph examinations were taken at entry,six months,twelve months and eighteen months after treatment,respectively.Results Twenty-two cases in leflunomide group and 29 cases in methotrexate group were followed up to eighteen months.BASDAI in leflunomide group was significantly lower(P

Objective To study the immunological changes and clinical features of pachydermodactyly.Methods Thirteen cases of pachydermodactyly were studied and the literature about this disease was reviewed.Results The mean disease onset age was (16?3)years,11 of whom were male,2 were female;clinical feature was chronic non-inflammatory bulbous swelling of proximal interphalangeal joints,most of which distributed symmetrically;there were no abnormal results in immunological examination;X-ray showed only soft tissue swelling with no articular or bone damage.Conclusion Pachydermodactyly belongs to rheumatological diseases,and should be differentiated from other arthritis involving PIP joints.

[Objective]To study the effects of Gusuibu Zonghuangtong on level of TNF-? and IL-6 in macrophagocyte stimulated by PMMA particles.[Method]The rabbits were divided into six groups.Group A:only monoculear cells;group B:monoculear cells+PMMA particles;group C:monoculear eells+PMMA particles +2mlcontrol-serum;group D:monoculear cells +PMMA particles +2 ml drug-serum;group E:monoculear cells + PMMA particles +3 ml drug-serum;Group F:monoculear cells + PMMA particles +5 ml drug-serum.Each group was cultured for 4 hours,and then the TNF-? and IL-6 of each groupwas determined.[Result]The levels of TNF-? and IL-6 were much higher in Group B than that of Group A,much lower in Group D,E,F than that of Group C(P0.05).[Conclusion]The PMMA particles could stimulate macrophagocyte to excrete TNF-? and IL-6,which can be inhibited by Gusulbu Zonghuangtong.Gusuibu Zonghuangtong is hoped to have clinical utility in the prevention and treatment of aseptic loosening of prosthesis.

Objective To investigate the effect of Danzhijiangtang capsule on serum,fat in type 2 diabetic rats.Methods The model of type 2 diabetes mellitus rats were established by injecting small does streptozotocin(STZ)into abdomen and feeding high sucrose-fat diet.All the rats were divided randomly into five groups.The level of blood glucose,serum insulin,insulin sensitivity index,blood fat(triglyceride, cholesterol,high-density lipoprotein,low-density lipoprotein),free fatty acid after treated were examined. Results Danzhijiangtang capsule could decrease the level of blood fat.Conclusion Danzhijiangtang capsule could improve the blood fat in type 2 diabetic rats.
