Two lab-scale expanded granular sludge bed reactors were operated using granular sludge and river sediments as seed sludge respectively, through gradually lowering down the inner pH values, acid-tolerant methanogenic granular sludge with good methanogenic activity were acquired and formed. Two EGSB reactors could be operated steadily under the condition of pH 5.8～6.2, and their volumetric loading rates were about 5.5～7.5 kg COD/(m3/d), the COD removal efficiencies were about 90%. The granular sludges taken from two reactors could maintain relatively higher methanogenic activity under low pH, and the relative activities of the granular could be 51.78% and 55.6% of the value with the condition of pH 7.0 when pH was 5.5. Studies on the diameter distribution, settling velocities, concentrations of different metal elements and microbiological characteristics of these acid-tolerant granular sludges were also conducted.

Objective To analyze the epidemiological characteristics of the imported malaria cases in 20 counties at the bor?der region of Yunnan Province from 2012 to 2014,so as to provide the evidence?based proof for adjusting the strategies in the elimination stage. Methods The malaria epidemic data of the 20 border counties in Yunnan Province from 2012 to 2014 were collected and analyzed by using Microsoft Excel 2010. Results From 2012 to 2014,a total of 1 558 malaria cases were report?ed in the 20 border counties in Yunnan Province,among which,1 336 were imported cases,accounting for 85.75%(1 336/1 558),and 222 were indigenous cases,accounting for 14.25%(222/1 558). The number of the imported cases in the above years took up 80.00%(544/680),89.10%(425/477)and 91.52%(367/401)of the total reported cases in the whole year,re?spectively. Among all the 1 336 imported cases,1 045(78.22%)were infected with Plasmodium vivax,284(21.26%)were in?fected with P. falciparum,3 were infected with P. malariae,3 were mixed infection and 1 was an unclassified case;2 patients died. And 95.58%of the cases were mainly infected in Myanmar(1 277 cases). Young and middle?aged adult of 20-40 years who worked overseas were the predominant(802 cases,60.03%)and most of the cases occurred from April to June of the year (679 cases,50.82%). Those cases mainly distributed in Tengchong(459 cases),Ruili(366 cases),Yingjiang(191 cases)and Mangshi(78 cases). Conclusions The epidemic situation of imported malaria is serious in the border region of Yunnan Prov?ince. Therefore,the surveillance system of malaria control needs to be well planned and managed to ensure timely case detection and prompt response at the elimination and post?elimination stage.

Objective To discuss the impact of a immunosuppressive protocol using tacrolimus combined with mycophenolate without steroid on glycometabolism after liver tansplantation (LT).Methods 295 adult liver transplant recipients were under investigation and divided into two groups,to receive immunosuppression therapy using tacrolimus and mycophenolate with (n =142) or without steroid (n =153).The fasting blood-glucose level,rate of hyperglycemia,infection and metabolic complications were followed up at 1st,2nd,4th,8th,12th,16th,20th and 24th week after LT.Results There were no significant differences between two groups in gender,age.body weight and FBG level before LT.In both groups,the FBG levels were significantly elevated immediately and reached the peak at 1st week after LT,then gradually decreased over time post-LT.The FBG level and rate of hypcrglycemia were significantly lower in steroid-free group than in steroid group in each observation time point with the differences being significant (P＜0.05) at 4th week post-LT.The overall rate of hyperglycemia was 52.9％ in steroid free group and 76.8％ in steroid group with the difference being significant between the two groups (P＜0.05) and a risk ratio of 2.94 (steroid-free group versus steroid group).The rate of acute rejection was slightly higher in steroid-free group (8.50 ％ ) than in steroid group (7.75％ ) (P ＞ 0.05 ).Also the incidence of intention badness,infection and hypercholesterinemia was significantly lower in steroid group than in steroid-free group.Conclusion The immunosuppressive protocol without steroids is safe and effective of reducing the risk of hyperglycemia and metabolic complications after LT.

Objective To evaluate the applied value of functional immunity measured by the ImmunKnow assay in the diagnosis of post-transplant infection in Chinese 1iver recipients.Methods Thirty-eight normal adults and 68 adult liver transplant recipients were under investigation.Whole blood samples from either normal volunteers(each sample for one person)or the liver recipients(one or more samples for one person)were collected freshly and cultured within 6h.The CD4+T cells were selected and their ATP value was assayed the next day.The liver recipients were grouped in stable status(n=52)or infection(n=64)according tO their clinieal manifestation.Results The average ATP value in the recipients with infection after liver transplantation was 165.7±100 μg/L,significantly lower(P＜0.05)than that in stable recipients(309±126 μg/L)or normal volunteers (292±83 μg/L).The low ATP levels in post-transplant recipients had fair good correlation to infection clinically(RR=0.5021,P＜0.01).Infectious risk was high when ATP value was less than 165μg/L(OR=11,95%CI 3.9-32.2,P＜0.01).Specificity and sensitivity of low ATP value in post-transplant infection were 86.53%and 73.81% respectively,Conclusion ImmuKnow assay provides a new tool in monitoring immune status in post-transplant recipients,and call helpfully predict and diagnose clinical infection.

Objective To study effect of eleetromyograghie(EMG) biofeedback training on three kinds of u- rinary ineontifienee.Methods Nineteen patients with urinary incontinence were treated by means of EMG biofeed- back training twice a day for six weeks.The treatment was performed with a device,which can detect the EMG ampli- tude of the pelvic muscle and deliver electric stimulation accordingly.Results After 6 weeks of treatment,the inci- dence of uretbrorrhea was reduced by 41%,and the frequency of micturition was decreased by 38% ,while the fre- quency of urination in one day reduced to 9 to 13.The general subjectively rated improvement rate of patients was 53% ,while the general objectively one was 58%.Conclusion Biofeedback training has significant therapeutic: eftects on patients with urinary incontinence.

Objective To investigate the mRNA expression of TLR4 mRNA and TLR2 in the peripheral blood mononuclear cells(PBMC)from the patients with systemic lupus erythematosus (SLE). Methods The mRNA of TLR4 and TLR2 were detected in the patients with SLE (n = 41) and the normal healthy control (n = 24) with the method of Taqman Real-time PCR. Results The mRNA expression of TLR4 was significantly higher in active SLE patients than that in inactive SLE patients and the normal healthy control (P
