Conclusion Heavy metals exposure through soil-mouth pathway will increase the total health risk of heavy metal to exposed population.

Objective To analyze the incidence,clinical feature and the risk factors of invasive fungal infection in pediatric intensive care unit (PICU). Methods We retrospectively summaried the invasive fungal infection in our PICU from Jan 2007 to Dec 2009 in order to analyze the incidence, clinical feature and the risk factors of invasive fungal infection in PICU. Multiple clinical data were collected such as pediatric critical illness score, mechanical ventilation, urinary drainage tube, indwelling gastric canal and continuous blood purification. Results ( 1 ) The incidence rate of invasive fungal infection was 1.65 % ( 35/2 116 ). The morbidity was 20. 00% ( 7/35 ). ( 2 ) Mean infected day was ( 10. 4 ±- 8. 3 ) d after admission. The clinical manifestations included fungal pneumonia( 60. 0% ), peritonitis ( 14. 3% ), urinary tract infection ( 11.4% ),intestinal tract infection(8. 6% ) ,sepsis(2. 9% ) and meningitis(2. 9% ). All of the patients had used broad spectrum antibiotic. (3) The risk factors of invasive fungal infection included lower pediatric critical illness score, mechanical ventilation, indwelling gastric tube, urinary drainage tube and continuous blood purification.(4) Candia albicans was the predominant pathogen in invasive fungal infection. Conclusion Invasive fungal infection has become one of the main nosocomial infection in PICU. Lung is most commonly involved and candida albicans is the major pathogen. Using antibiotics appropriately, decreasing unnecessary invasive performance,and rationally using antifungal agent mi.ght be effective strategy for invasive fungal infection in PICU.

Objective To summarize the experience in one case of adult-to-adult combined liver-kidney transplantation.Method In Sep.2007,one case of adult-to-adult liver-kidney transplantation from the same living donor was performed on a patient with liver cirrhosis (liver failure decompensation) and chronic renal failure (uremia).There was a donation of the right liver with the middle hepatic vein and right kidney in the same time from the living donor.The piggyback liver transplantation and ectopic kidney transplantation were performed for the recipient.Basiliximab and methylprednisolone were given for immune induction therapy in operation.Tacrolimus,MMF and prednisone were given for anti-rejection.There were hepatoprotective treatment,anti-infection treatment and nutritional support for the donor and recipient after operation.The follow-up period has now been more than five years.Result The donor and the patient were smooth in the perioperative period.The liver and kidney function of the donor is well so far.There was no significant influence on quality of life of the donor.The transplanted liver and kidney function of the recipient is well so far.There were no significant complications for the recipient.Conclusion The living liver-kidney transplantation is an effective means for the treatment of liver and kidney failure.The safety can be ensured for the donors that donate the right liver and one kidney simultaneously.

Objective To analyze the clinical features,diagnosis and treatment of thrombotic thrombocytopenic purpura (TTP) in patients with systemic lupus erythematosus (SLE).Methods Clinical manifestations,laboratory findings,diagnosis,treatment and prognosis of 14 SLE patients with TTP were retrospectively analyzed.Results Of the 14 patients diagnosed with SLE and TTP,4 were men and 10 were women.The median age at diagnosis was 23 (17-69) years old.In five patients,the onset of SLE preceded TTP,and in nine patients SLE and TTP occurred simultaneouslv.All the 14 patients had thrombocytopenia and hemolytic anemia,12 had fever,11 had neurologic abnormalities,and 11 had renal dysfunction.Eight patients presented with the classic pentad of symptoms.Six patients were given steroids (alone or in combination with intravenous immunoglobulin and cyclophosphamide),and eight patients were treated with steroids in combination with plasmapheresis,with response rates of 2/6 and 6/8,respectively.Six patients died,with overall mortality rate of 6/14.No patients relapsed during the follow-up period.Conclusions SLE and TTP share some similar clinical symptoms.As a result,repeated examinations of peripheral blood smears are very important for early diagnosis.The renal damage in patients of co-existing diseases is more serious than those with TTP alone or SLE alone.Early diagnosis and prompt treatment with plasma exchange and steroids may improve the prognosis in SLE patients with TTP.

objective To analyze the correlation between the level of serum uric acid and the clinical and pathological features of IgA nephropathy.Methods Totally 148 patients diagnosed as IgA nephropathy by renal biopsy in our hospital from January 2007 to December 2010 were divided into hyperuricaemic group(41 cases)and non-hyperuricaemic group(107 cases)according to the level of serum uric acid.The clinical parameters and renal pathology grade were compared.Results There were significant differences between hyperuricaemic group and non-hyperuricaemic group in the incidences of hypertension(63.4%vs 38.3%),disease duration[(18.90±10.12)months vs(9.46±3.91)months]and body mass index[(22.81±3.60)kg/m2vs(15.32±2.54)kg/m2](all P<0.05),while no differences in age and sex(both P>0.05).The blood urea nitrogen(BUN)[(8.93±4.28)mmol/L vs (5.21±2.18)mmol/L],creatinine(Cr)[(155.96±107.72)μmol/L vs(79.52±40.01)μmol/L],serum triglycerides[(2.11±1.06)mmoVL vs(1.86±1.20)mmol/L]and 24-hour urine protein amount [(4328.16±1434.25)mg/24 h vs(2885.10±1388.15)mg/24 h]were significantly different between the two groups(all P<0.05).The percentage of Lee's grade I+Ⅱin hyperuricaemic group was 12.2%,and IV+V grade was 39.0%,while percentage of Lee's grade I+Ⅱin non-hyperuricaemic group was 25.2%,and IV+V grade was 16.9%(P<0.05).Tubulointerstitial lesions(TIL)gradeⅢ+IV was more in hyperuricaemic group,which was 68.3%,while TIL grade II was more in non-hyperuricaemic group,which was 76.6%.Renal artery damage grade II+Ⅲ was more in hyperuricaemic group.which was 73.2%,while renal artery damage grade 0+1 was more in non-hyperuricaemic group,which was 69.2%.Conclusion The level of serum uric acid was related with 24-hour urine protein amount,blood pressure and kidney function in IgA nephropathy,and Lee's grade,TIL grade and renal artery damage grade were severe in hyperuricaemic group.

Objective To investigate the association between the number of periphery artery atherosclerotic stenosis and cardio-cerebrovascular events in elderly people.Methods Totally 163 subjects aged 60 years and over (median age 83 years) in special outpatient service of PUMC Hospital were retrospectively reviewed and underwent Doppler ultrasound of carotid,lower extremity,and renal artery.General conditions,cardio-cerebrovascular events,risk factors and results of periphery artery ultrasound were assessed.Results Age (F =13.413,P ＜ 0.001 ),hypertension,hyperlipidemia and the statin users(x2 =24.961、13.592、16.207,all P＜0.001) significantly enhanced along with increasing number of peripheral artery stenosis (P＜0.001).The more the peripheral arteries stenosis,the more cardio-cerebrovascular events occurred (x2 =15.258,P ＜ 0.001).Symptomatic peripheral artery obstructive disease increased the prevalence of cardio-cerebrovascular events.Conclusions Multiple periphery artery atherosclerotic stenosis is associated with cardiocerebrouascular events and Doppler ultrasound is effective to detect high-risk patients.

objective To explore a new method of repairing skin defects complicated with fracture and tendon rupture at the middle and distal sections of the second to fifth fingers. Methods The reversed dorsal metacarpal island flap was designed to be pedicled on the digital proper artery-common digital artery-fingerweb artery-dorsal metacarpal artery-cutaneous branch of dorsal metacarpal artery.In repairing digital palmar skin defects,after the flap was dissected,the proximal incision was extended along the direction of dorsal metacarpal nerve to harvest an enough length of the nerve so that the dorsal metacrppal nerve can be anastomosed with the digital proper nerve to restore the sensation of finger pulp.From the June 2003 to March 2009,the flap was used to repair 26 fingers in 24 patients with middle and distal digital skin defects complicated with fracture and tendon rupture.They were 17 men and 7 women,aged from 16 to 63 years (average,37 years).There were 15 cases of palmar skin defect and 9 cases of dorsal skin defect.In the 2 cases of combined tendon defects,a section of the extensor tendon of index(or little) finger was dissected together with the flap to repair the tendon rupture. Results The areas of the flap ranged from 3.1 cm ×1.6 cm to 6.0 cm × 4.0 cm.The flaps survived in all 24 cases without any vascular crisis.Twenty-two patients obtained an average follow-up of 14 months (from 4 to 32 months) but 2 were lost to the follow-up.The flaps were fine in texture,colour and appearance.The finger pulps appeared full and recovered sensations of pain and temperature.The average two-point discrimination was 7.5 mm (from 5 to 9 mm).Sensory function evaluation revealed an outcome of S3 + ～ S4.Tendon adhesion occurred in 4 cases which recovered digital function following secondary lysis 3 to 6 months postoperation. Conclusion Application of the reversed dorsal metacarpal island flap pedicled on the digital proper artery is a good way to repair skin defects complicated with fracture and tendon rupture at the middle and distal sections of the second to fifth fingers.
