An effective method has been developed for laboratory scale production of IgG. Hybridomas were cultured in serum-free media with 2% IgG-free ascites. Cell density of up to 3.55 × 10 6cells/ml and antibody concentration of 135μ g/ml after purification were abtained, which is four time more than total production of that of IgG concentration in serum-free media. This in vitro method allows great improvement in antibodies production in batch tissue culture. The method reported here is easy to handle and is economical and universally adaptable.

Purpose To investigate renal cortical blood perfusion in patients with nephrotic syndrome (NS) by region of interest (ROI) quantification.Materials and Methods Twenty-one patients with NS treated at Wuhan Union Hospital from September 2014 to January 2015 (NS group) and twenty-nine matched healthy subjects (control group) were enrolled in our study.High frequency blood flow dynamic images of the left kidney for all the subjects were acquired by color Doppler (Philips iU22).Resistance index (RI) of interlobar artery,arcuate artery and interlobular artery were measured.Vascularization index (VI),flow index (FI),vascularization flow index (VFI) were further analyzed by ROI quantification at Q-LAB work station.Results ① The signals of renal cortical blood flow in NS patients were sparse and slim;while the signals in the control group were continuous,most of which reached the edge of renal cortical.② No statistical differences of RI values of interlobar artery and interlobular artery were found between the two groups (P＞0.05);③ The renal cortical blood perfusion in the NS patients decreased significantly compared with that in control group,and the renal cortical VI,FI and VFI values in NS group were significantly lower (P＜0.01).④ Bland-Altman analysis showed that there was good repeatability in the measurement of renal cortical VI,FI and VFI.Conclusion Color Doppler flow imaging combined with RO1 quantitative technique can assess renal cortical blood perfusion accurately,which provides diagnostic information for early detection of renal damage.

Chronic infection of hepatitis B virus(HBV)presents one of the serious public health challenges worldwide.Current treatment of chronic hepatitis B(CHB)is limited,and is composed of interferon and nucleoside/nucleotide reverse transcriptase inhibitors(NRTI).Interferon is poorly tolerated and is only responsive in a small fraction of CHB patients and NRTIs often face the problem of emergence of drug resistance during long-term treatment.The current treatment of CHB earl be improved in several ways including genotyping mutations associated with drug resistance before treatment to guide the choice of NRTIs and suitable combinations among NRTIs and interferon.It is important to continue research in the identification of novel therapeutic targets in the life cycle of HBV or in the host immune system to stimulate the development of new antiviral agents and immunotherapies.Several antivirai agents targeting HBV entry,cecDNA,capsid formation,viral morphogenesis and virion secretion,as well as two therapeutic vaccines are currently being evaluated in preclinical studies or in clinical trials to assess their anti-HBV efficacy.

Effect and safety of repeated embryo aspiration for reduction of muhifetal cervical pregnancy Was retrospectively evaluated.Three women with muhifetal cervical pregnancy successfully received conservative treatment of repeated embryo aspiration under the guidance of transvaginal ultrasound,and the gestational sac contents were aspirated completely.Local(2.5～5.0 mg injectable methotrexate,MTX) or systemic medication was used.Our findings showed that repeated embryo aspiration for reduction of cervical multifetal pregnancy could improve the coupe of disease,decrease systemic medication of MTX,and discontinue a cervical pregnancy within 8 weeks effectively and safely.However,the mminimum therapeutic dose of MTX remained to be explored.

Objective: To establish a female SPF BALB/c mouse model of antibiotic-associated intestinal microflora disturbance and analyze the effect of lactobacillus acidophilus.Methods: Female SPF BALB/c mice were treated with ceftriaxone in drinking water for five days,and followed by oral gavage of sodium chloride as natural recovery group or lactobacillus acidophilus(108CFU/mL) as therapeutic group.After seven days the intestinal microflora of the cecum content was abstracted and computed by plate counts and 16S rDNA-based PCR-DGGE method.Results: Plate counts indicated that the number of original bacterium lacticum and bacillus bifidus decreased significantly and enterococci proliferated abnormally after antibiotic treatment.After lactobacillus acidophilus treatment,the number of physiological bacteria and enterococci go back to normal levels.DGGE profile clearly indicated that the dominant bacteria changed and the bacterial diversity of intestinal microbiota was obviously decreased in the antibiotics treated group. Conclusion: Oral gavage of lactobacillus acidophilus has adjustment effect on Ceftriaxone induced intestinal microbiota disturbance.PCR-DGGE is a rapid、effective molecule method to reveal the whole microbiota status.

In order to prepare the recombinant vasoactive intestinal peptide (VIP) using intein mediated rapid purification system,the cDNA encoding the recombinant VIP was designed and synthesized according to the preference of E.coli,and then was cloned into the expression vector PTWIN. The recombinant plasmid PTWIN-VIP was transformed into expression host E.coli strain ER2566.The fusion protein consisting of the recombinant VIP,intein and chitin binding domain was expressed and purified by chitin affinity chromatography. The target peptide was released from the fusion protein by changing the temperature and the pH of the cleavage buffer. The molecular weight of the recombinant VIP was determined by the mass spectrometry and the results was conformity with the theoretical value. The preliminary bioactivity assay indicated that the recombinant VIP decreased the serum resistin levels significantly in LPS-induced acute inflammation. The preparation and the characterization of anti-inflammatory effects of the recombinant VIP layed the foundation for its further application.

OBJECTIVETo analyse dental crown fracture occurrence situation in the long-term mastication process, and discuss the correlation factor of crown fracture occurrence.

METHODSFrom December, 2005 to December, 2007, 255 crown fracture teeth were chosen as the object of study. The sex, age, teeth position, fracture position and occlusal state of patients were analyzed.

RESULTSIn 255 teeth, 1) 76 teeth (29.8%) were maxillary first molars, 45 teeth (17.6%) were mandibular first molars, 41 teeth (16.1%) were maxillary second molars, 37 teeth (14.5%) were mandibular second molars, 32 teeth (12.5%) were maxillary second premolars, 15 teeth (5.9%) were maxillary first premolars, 9 teeth (3.5%) were mandibular second premolars. 2) The fracture position of 158 teeth (62.0%) overlapped with pit and fissure. The fracture position of 97 teeth (38.0%) occurred in dental inclined surface. 3) The occlusal state of 85 patients (33.3%) was normal. The occlusal surface shape of 55 patients (21.6%) was unnormal. The occlusal shape of 115 patients (45.1%) was unnormal.

CONCLUSIONThe teeth position and occlusal state has certain relations with occurrence of dental crown fracture. Occlusal force was the basic factor for dental crown fracture, but it was not the only one.

Objective To compare the efficacy of continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) on polycystic kidney disease (PKD) patients with end-stage renal disease (ESRD). Methods Retrospective analysis was made on 29 patients with PKD who carded out dialysis therapy for over 3 months in our department from January 2001 to December 2007. They were divided into the CAPD group (10 cases, 34.5%) and HD group (19 cases, 65.5%). Ten cases of non-PKD CAPD patients were randomly selected as the control, who matched the CAPD group in terms of age and gender. The patient information was recorded, such as general data, initial dialysis data, comphcations, survival time, quit of dialysis or death, etc. Kaplan-Meier method and Log-rank test were adopted to analyze the survival rate. Results The survival rates of 1-, 3- and 5-year for the CAPD group were 90%, 75% and 25% respectively, while for the HD group were 94.4%, 67.6%, and 48.3%, and for the control were 83.3%, 44.4% and 22.2% respectively, with no significant differences among 3 groups (P>0.05). group and the control were quite similar. The incidence of peritonitis for the CAPD group (0.62 times/patient year) was similar to that for the control (0.30 times/patient year)(P>0.05). The duration of the lust peritonitis[(23.5±4.0) months vs (20.0±15.8) months] and the catheter exit-site infection (0 time vs 1 time) for two groups were similar as well (P>0.05). One patient had hernia in CAPD group and no patient in control group had hernia. The incidence of peritoneal dialysate leakage was similar between these two groups. In the HD group, two patients (10.5%) had cerebral hemorrhage resulting in death, and 10 patients (52.6%) had cystic hemorrhage, 5 out of whom underwent operation due to repeated cystic hemorrhage and 2 cases received unilateral nephrectomy because of severe hemorrhage. No patient in CAPD group had cerebral hemorrhage but 1 patient (10%) had cystic hemorrhage and recovered after conservative treatment. The hemorrhage complication incidence of CAPD group was significantly lower than that of HD group (P<0.05). Conclusions The prognosis and complication incidence in PKD and non-PKD patients treated with CAPD are similar. The prognosis of PKD patients treated with CAPD or HD is also similar, and the risk of hemorrhage complications of PKD patients treated with CAPD may be decreased compared with those treated with HD. PKD patients can choose HD or PD as the initial therapy of ESRD unless existence of hernia or intolerance. PKD is not the contraindication of PD.
