Objective To investigate the roles of renin-angiotens in system(RAS)and aldosterone(ALD),endothelin(ET),nitricoxide(NO)in patients with renal hypertension(40 cases)and adrenocorticoadenomas(35 cases),35 normal subjects were included in the study as controls.Methods Radioimmunoassay(RIA)was used to de termine the plasma concentrations of the renin,angiorensin Ⅱ(AⅡ),aldosterone,ET in the abovecases.Enzymicas say was adopted to examine the plasma concentration of the nitricoxidesynthase(NOS).Results TIhe plasma concentrations of renin,angiotennsin Ⅱ,aldosterone,endothefin in the patients with renal hypertension were significantly higher than those in the control group(P＜0.01)except with the concentration of NOS,which were lower than that in controls(P＜0.05);the plasma concentrations of the ALD,ET,in the patients with adrenocorti-caladenoma were higher that those in controls(P＜0.01)but renin and A Ⅱ were lower(P＜0.05).Conclusion Determination of the plasma renin,angiotensionⅡ,aldosterone and NO might be able diagnose renal hypertension and adrenocorti coadenoma earlier.

Objective To discuss the treatment effect of well-differentiated thyroid carcinoma.Methods From 1992 to 2002,42 cases of well-differentiated thyroid carcinoma invading the laryngotrachea were treated in shanxi tumor hospital.Radical tumor resection were 6 cases,local shaving-off tumor resection were 32 cases and incomplete tumor resection were 4 cases.Some patients received postoperative radiotheraPy.Results In the 42patients,the overall 5-year survival rates were 76.2%(32/42).Conclusion Although well-differentiated thyroid carcinoma invaded the laryngotrachea,the operation can increase the curative effect and the patient's living standand.

AIM:To investigate the effects and possible mechanisms of baicalin on the atherosclerosis rabbits.METHODS:Thirty healthy New Zealand white rabbits were divided randomly into five groups:normal control group(A group,n=6)and fed with normal diet,atherosclerosis model group(B group,n=6),baicalin therapic group(C group,n=6),bacalin preventive group(D group,n=6),and positive control group(E group,n=6),the last four groups fed with hypercholesterol diet for 12 weeks.Treated with bacalin 300 mg/(kg?d),and simvastatin 5 mg/(kg?d)additionally for 2 weeks in C and E group respectively from the tenth week.Treat with bacalin 100 mg/(kg?d)for 12 weeks in D group.Serum lipids and liver lipids were detected with standard enzymatic assays.Atherosclerotic plaque/intima size ratio of area and NF-?B content in blood vessel tissue were examined.Enzyme-linked immunosorbent assay(ELISA)was employed to monitor the levels of serum TNF-?,IL-1? and Adiponectin.RESULTS:Atherosclerotic plaque/intima size ratio of area decreased in C,D and E group than in B group(P

The proliferation of vascular smooth muscle cells plays an important role in the initiation and aggravation in cardiovascular diseases such as hypertension, arteriosclerosis, restenosis. This article reviewed the progress in the studies on extracellular influencing factors, intracellular signal transduction, cell cycle of vascular smooth muscle cells and the relative drug research and development.

60 cases with a history of recurrent respiratory infections were studied The serum levels of immunoglobulin G and A were measured by means of radial diffusion and the results were compared with 41 normal subjectsof the same age. In 23 cases (38. 3%), serum IgA level was below meanvalue-SD. It was remarkably decreased in 8 patients with prolonged pneu-monia(P≤0.05). The serum IgG concentration was elevated above mean va-lue + SD in 14 patients, 8 of whom suffered from bronchitis. There was,furthermore, another group of 7 patients with bronchitis whose IgA levelwas elevated above mean value + SD. The results suggested that deficiencyof serum IgA might be a cause of recurrent respiratory infections andmight give rise to a prolonged course of pneumonia in some patients.

OBJECTIVE:To analyze the general patterns and characteristics of drug-induced lupus (DIL) induced by inflix-imab,and to provide reference for the safety of drug use. METHODS:Usinginfiximab,lupusas searching words,inflix-imab-induced DIL literatures included in CJFD,VIP and PubMed from Jan. 2002 to Jun. 2016 were retrieved and analyzed. RE-SULTS:Totally 30 effective literatures were retrieved,involving 31 DIL patients,there were 8 male cases (25.81%) and 23 fe-male cases(74.19%);17 patients aged more than 50(54.84%). 20 cases occurred within 5-24 weeks(64.51%). 16 patients re-ceived infliximab alone (51.61%). Main clinical manifestations were skin rash or photosensitivie enteritig (15 cases),joint pain (16 cases,multiple arthritis and synovitis)and fever(12 cases). 5 patients suffered from 3 above symptoms simultaneously. Labo-ratory examination mainly manifested as antinuclear antibody,double stranded DNA antibody and anti-histone antibody positive. Thirty patients with DIL received drug withdrawal or steroid hormones treatment,among which the symptoms of 26 patients disap-peared after drug withdrawal or treatment within 6 months,and 1 patient deteriorated. CONCLUSIONS:DIL-induced by inflix-imab invovle patients'age and gender,disease types,family history and other factors. Clinicians should be aware of rules and char-acteristics of DIL induced by infliximab,and tighten drug use monitoring to reduce ADR.

Immune thrombocytopenia (ITP) of childhood is the most common hemorrhagic disease which is characterized by isolated thrombocytopenia.Depending on individual patient characteristics,appropriate initial management for newly diagnosed ITP may be either watchful waiting or pharmacologic intervention.The main options for initial pharmacologic intervention include a single dose of intravenous immune globulin(IVIG) and/or a short course of glucocorticoids.For ITP children with severe or life-threatening bleeding,it is recommended that both platelet transfusions and the combination of pharmacotherapy.Approximately 20 percent of children who present with ITP will progress to chronic ITP(CITP).Children who develop CITP should have an additional evaluation to exclude other disorders.The pharmacologic options for CITP include Rituximab,and thrombopoietin (TPO)/TPO receptor agonist (Romiplostim or Eltrombopag).Combination therapy and novel immunological targeting drugs become more effective treatment options.Splenectomy is only suit for a small number of children with chronic refractory ITP patients who present significant and persistent hemorrhagic symptoms requiring repeated pharmacologic interventions.

Objective:To evaluate the effect of Ginseng-Sini in early goal directed treatment septic shock under PICCO.Methods: Forty four patents with septic shock were randomly divided into control group, which treated with Ginseng-Sini on the basis of routine treatment under PICCO, observation groups, which treated with only the basis of routine treatment under PICCO. Before and after the drugs were given for 6 hours, HR, IMAP, CVP, SpO2, Lac, CI, ITBVI, SVRI were monitored.Results: Before treatment, HR, IMAP, CVP, SpO2, Lac, CI, ITBVI, SVRI of the observation group were not different from the control group(P>0.05); after 6 hours of treatment, CI of the observation group were higher than that of the control group(P<0.05).Conclusion: Ginseng-Sini in the early goal directed of septic shock is effective, especially in improving tissue perfusion.

Objective To explore the impact of lung-protective mechanical ventilation (low tidal volume and optimal positive end-expiratory pressure (PEEP) on cerebral perfusion pressure (CPP) and cerebral oxygen metabolism.Methods Forty patients with severe cerebral injury along with respiratory failure were randomly assigned into two groups:lung-protective ventilation group A and conventional ventilation group B.Group A was planned to prescribe tidal volume 6 ～ 8 mL/kg,initial FiO240％,PEEP gradually increasing from 2 cmH2O to matched with FiO2 elevation,but the FiO2 was kept at permissive lower level.Group B was formulated with tidal volume 8 ～ 12 mL/kg,PEEP stepwise increasing from 0 2 cmH2O to match with FiO2 elevation,but PEEP was kept at permissive lower pressure.The intracranial pressure (ICP),mean arterial pressure (MAP),CPP,arterial and jugular venous blood gas were monitored.Results PEEP (8.2±3.32 cmH2O),ICP (19.7 ±3.6 mmHg),PaCO2 (54±7.3 mmHg),jugular venous carbon dioxide partial pressure (PjV CO2,56.7 ± 9.6 mmHg) in group A were higher than those (5.7±2.3 cmH2O,16.9±3.8 mmHg,41 ±5.2 mmHg,49.8 ±6.9 mmHg) in group B (P＜ 0.05 or P ＜ 0.01).VT,FiO2 in the group A were lower than those in the group B.There were no differences in PaO2/FiO2,jugular venous oxygen saturation (SjVO2),MAP,and CPP between two groups.PaCO2 were significantly correlated with CPP (r =0.368,P =0.019) while there was no correlation with ICP,PaO2,SjVO2,PjVCO2 (all P ＞0.05).CPP (69.7 ± 12.3 mmHg) was higher in case of PaCO2 (46 ～60mmHg) than those (61.5 ±9.1 mmHg) in case of PaCO2 (35 ～45 mmHg).There was correlation between PEEP and ICP (r =0.436,P =0.005).When PEEP was divided into three groups:≤52 cmH2O,6 ～ 102 cmH2O and ＞ 102 cmH2O,ICPs were different one another among three groups.When PEEP ＞ 102 cmH2O,it had a distinguished negative correlation with CPP (r =-0.395,P =0.017),while PEEP ≤ 102 cmH2O,CPP presented decreasing tendency.SjVO2 correlated with PaO2 (r =0.403,P =0.014) and PjVCO2 (r =-0.502,P =0.001) respectively.There were no significant relationships between SjVO2 and CPP,ICP,MAP,PEEP,respectively.Conclusions Lung-protective mechanical ventilation was relatively safer in patients with severe cerebral injury compared with conventional mechanical ventilation.Mild PaCO2 elevation (46 ～ 60 mmHg) combined with higher PEEP (＜ 102 cmH2O) did not decrease CPP.There was no difference in SjVO2 between the two modes of mechanical ventilation,suggesting no changes in cerebral metabolism occurred.
