Objective To investigate the effect of high-flux hemodialysis on mineral and bone metabo-lism( MBD) in diabetic kidney disease patients with maintenance hemodialysis .Methods 60 cases with diabetic kidney disease undergoing maintenance hemodialysis were studied and they were randomly divided into two groups according to the number table method .Patients in each group were treated using either high-flux dialyzer or low-flux dialyzer for 6 months.Blood calcium(Ca), blood phosphorus(P), calcium*phosphorus(Ca*P), alkaline phosphatase(AKP), parathyroid hormone(PTH), and 25 hydroxy vitamin D3(25-OH-D3),etc were deter-mined at the start and end of the study .Results In high flux dialysis group , serum P, serum Ca*P, and PTH levels was(1.52 ±0.50)mmol/L,(3.05 ±1.19)pg/L and(368.61 ±235.32)pg/L respectively, which was sig-nificantly decreased than before treatment ((1.78 ±0.55)mmol/L,(3.94 ±1.31),(427.45 ±288.93)pg/L) (P<0.05), while serum Ca, and 25-OH-D3 levels were(2.3 ±0.16)mmol/L and(21.64 ±8.51)nmol/L respectively, which were increased significantly than before treatment ((2.12 ±0.18)mmol/L,(16.77 ±7.69) nmol/L)(P<0.05), yet in low flux dialysis group serum Ca, P, AKP, PTH, and 25-OH-D3 didn't change sig-nificantly before and after treatment ( P>0.05) .Conclusion High-flux dialyser provides a better effect on MBD for patients with diabetic kidney disease undergoing maintenance hemodialysis .

Bile acids (BAs) are a major component of bile salt, which plays a vital role in the metabolism of lipids in humans. Ninety-five percent of bile acids are recycled by the enterohepatic circulation (EHC), and therefore EHC is essential for bile acid homeostasis. There are four transporters that mediate the transmembrane transport of bile acids, each of which plays an important role in the enterohepatic circulation. Gene defects in bile acid transporters can lead to disorders of the enterohepatic circulation, ultimately leading to clinical phenotypes such as metabolic diseases and even death. Bile transporter expression is altered in patients with various metabolic disease states, suggesting that disruption of bile acid transporters may be a pivotal pathological mechanism for the development of metabolism diseases. Thus, many drugs targeting bile acid transporters are being developed. We provide a concise overview of the progress of bile acid transporters research, discuss the relationship between different bile acid transporters and disease development, and summarize the current progress in drug development targeting bile acid transporters.

OBJECTIVETo invesitigate the clinical effects of percutaneous closed reduction and cannulated screw internal fixation combined with external fixation in the treatment of unstable pelvic fractures.

METHODSFrom April 2006 to May 2009,29 patients with pelvic fractures of rotatory instability were treated with closed reduction and screw internal fixation combined with external fixation. There were 19 males and 10 females with an average age of 31 years old (ranged from 19 to 53 years). Based on the Tile classification,17 cases were type CI and 12 case were type C2. Tornetta standard and Majeed score were used to evaluated the clinical effect after operation.

RESULTSAll patients were followed up from 10 to 24 months with an average of 16 months. There were no nerve injuries and other organ injuries, only one case of infection was found and it was cured with wound dressing. Time of fracture union was from 14 to 18 weeks with the mean of 16.2 weeks. No loosening, slippage or breakage of the screw were found. According to the Tornetta standards,14 cases obtained excellent results, 10 good, 4 fair and 1 poor. The Majeed score was 87.2 ± 11.3, 16 cases got excellent results, 9 good and 4 fair.

CONCLUSIONClosed reduction and screw internal fixation combined with external fixation is an effective way to treat unstable pelvic fractures with Tile type C1 and Tile type C2.

Three bactreiophages of Pseudomonas aeruginosa were isolated from sewage and named as PaP1, PaP2 and PaP3. All belong to double-strand DNA phages, their genome is about 47kb, 34kb and 24kb respectively. The titre (pfu/mL) of three phages is respectively 109, 1011 and 1011, PaP1 is lytic phage, both PaP2 and PaP3 are lysogenic. Under electron microscope, All show icosahedral heads with diameter of 70nm, 55nm and 65nm respectively. PaPl belongs taxonomically to Myoviridae, and both of PaP2 and PaP3 belong to Pedoviridae. The phage-re-sistance and substitution phenomenon of the resistant flora for the sensitive were observed, and the mutation frequence of Pseudomonas aeruginosa resistant to the phage is about 1.4 ? 10-7 ~ 7.9 ?10-7 determined by end-point -titer method.

Objective To assess the risk factors that could influence the severity of esophageal inju- ry in patients with gastroesophageal reflux disease(GERD).Methods GERD patients diagnosed on the ba- sis of endoscopic reflux esophagitis or pathological results of 24 hour esophageal pH monitoring were divided into three groups as non-erosive reflux disease group(NERD)(n=83),mild esophagitis group(n=51) and severe esophagitis group(n=22).The clinic data and esophageal pH parameters were recorded in the three groups.A logistic regression was used to assess the joint influences of clinic characteristics,hiatus her- nia,and esophageal pH parameters on the severity of esophageal injury.Results Patients in severe esoph- agitis group were more likely to have advanced age and hiatus hernia.The number of supine long reflux epi- sodes measured by esophageal pH monitoring significantly increased with increasing grades of mueosal dam- age(P

Objective To evaluate the myocardial blood supply in patients with metabolic syndrome (MS) using 99Tcm-MIBI SPECT MPI. Methods A total of 342 patients were divided into four groups according to the number of abnormal metabolic indices: no abnormal metabolic index (Group 1), one abnormal index (Group 2), two abnormal indices (Group 3), three or more abnormal indices (Group 4). Each patient underwent two-day protocol of gated stress and rest 99Tcm-MIBI MPI. One hundred and three of the 342 patients were clinically diagnosed as MS and underwent CAG within 1 month after MPI. χ2test was used to evaluate the difference among the four groups and Kappa test to analyze the correlation between MPI and CAG. Results Compared with CAG, the diagnostic sensitivity, specificity, positive and negative predictive values by 99Tcm-MIBI SPECT MPI for coronary artery diseases (CAD) in 103 MS patients were 80.5% (33/41), 85.5% (53/62), 78.6% (33/42) and 86.9% (53/61), respectively. The correlation coefficient between MPI and CAG was 0.657 (P<0.001). The abnormal MPI rates in group 1, 2, 3 and 4 were 23.3% (10/43), 32.9% (26/79), 54.4% (56/103), and 57.3% (67/117), respectively (χ2=23.22, P<0.001). Conclusions In MS patients,99Tcm-MIBI SPECT MPI can be useful for evaluating myocardial blood supply and the myocardial ischemia rates may correlate positively with the number of abnormal metabolic indices.

Cathepsin B from Helicoverpa armigera (HCB) belongs to the group of cysteine proteinases. HCB is proved being involved in the degradation of yolk proteins during embryonic development,which is an acidic preferring enzyme and is resistant to SDS. The expression of the proenzyme may offer a model for investigating the activation of the enzyme. The HCB gene was constructed into pPIC9K and expressed in Pichia pastoris KM71 strain . After induction by methanol, HCB was expressed and secreted into the medium. The molecular weight of the recombinant procathepsin B was determined as about 38 kDa. The expressed product was confirmed to be HCB by immunoblotting assay using specific rabbit anti-HCB polyclonal antibody. The activity of the product was assayed by in situ hydrolysis (gelatin-SDS-PAGE). These results showed that HCB with proteolytic activity was expressed in P. pastoris KM71. This proenzyme can be used for further research on the activation of the proenzyme or industrial production.
