Objective To evaluate the effects of small dose of antithymocyte globulin(ATG)and zenapax in the induction therapy for kidney transplant recipients.Methods A series of 150 cadaver-donor kidney transplant recipients were randomly divided to 3 groups,ie,small dose of ATG group(total dose,2.1 -3.0 mg/kg;n=72),zenapax group(50mg,on the first and 14th d after operation;n=15)and controls without induction therapy(n=63).Follow-up was 6 months.The rates of acute rejection,delayed graft func- tion(DGF)and pulmonary infection were statistically compared among the 3 groups.Results During a 6-month period,in ATG,zenapax and control groups,acute rejection episodes occurred in 4 cases(5.5%), 1(6.7%)and 10(15.9%),respectively;DGF occurred in 3(4.2%),0 and 8(12.7%),respectively;pul- monary infection occurred in 4(5.1%),1(6.7%)and 3(4.8%),respectively;leucocytopenia occurred in 3(4.2%),1(6.7%)and 5(7.9%),respectively;thrombocytopenia occurred in 2(2.8%),1(6.7%)and 5(7.9%),respectively.Conclusions In the early stage of kidney transplantation,small dose of ATG and zenapax can be the optimal choice for induction therapy.

20% increase in serum creatinine over the last 6 months or progression to the range of 176-308?mol/L.Patients underwent abrupt cessation of cyelosporine and sirolimus maintenance at 1-2 rag/day after administration of 4-6 mg as first loading dose.Concomitant immunosuppression remained unchanged during conversion.Results Targeted sirolimus level was 4-8 ng/mL.Serum creatinine was dropped from pre-conversion level of(242.15?73.04)?mol/L to(188.32?58.96)?mol/L and (173.36?58.08)?mol/L at 3rd and 6th month respectively(P

Dendritic cells (DCs) are uniquely well-equipped antigen (Ag)-presenting cells. This function of DCs, coupled with their remarkable plasticity, renders them attractive therapeutic targets for immune modulation. Recent data have demonstrated a promising role for pharmacologic treatment as a means of generating potent regulatory DCs. Herein, the evidence that the potential of regulatory DC the-rapy is considerable and that there are compelling reasons to evaluate it in the setting of organ transplantation in the near future are discussed in this paper.

Objective To explore the rate of incidence of cerebral venous sinus thrombosis(CVST)in patients with idiopathic in- tracranial hypertension(IIH).Design Restrospective case series.Participants 92 cases with idiopathic intracranial hypertension.Meth- otis All patients diagnosed with papilledema from January 1,2000 through May 1,2007 at our ophthalmology center.Consecutive pa- tients with a diagnosis of papilledema were identified.Patients with space-occupying lesions,hydrocepbalus,or meningitis were excluded. The remaining patients were evaluated with lumbar puncture,magnetic resonance imaging(MRI)and magnetic resonance venography (MRV).Main Outcome Measures The rate of incidence of cerebral venous sinus thrombosis(CVST)in patients with idiopathic in- tracranial hypertension(IIH).Results Excluding patients with mass lesions,meningitis,or hydrocephalus,the occurrence of CVST was 7 (7.6%)of 92 patients with presumed IIH.One additional patients had a diagnosis of suspected CVST.Cerebral venous sinus thrombosis was diagnosed in 1 of the 7 patients with MRI alone,whereas it was evident in all 7 patients with MRV.Conclusions Cerebral venous si- nus thrombosis accounts for 7.6% of patients with presumed IIH in our ophthalmology services.Magnetic resonance venography in com- bination with MRI is recommended to identify this subgroup of patients.(Ophthalmol CHN,2007,16:410-413)

To explore the expression potential of heterogeneous genes using the backbone of infectious bronchitis virus (IBV) Beaudette strain, the ectodomain region of the Spike gene (1,302 bp) of IBV H120 strain was amplified by RT-PCR and replaced into the corresponding location of the IBV Beaudette strain full-length cDNA. This recombinant was designated as BeauR-H120(S1). BeauR-H120(S1) was directly used as the DNA template for the transcription of viral genomic RNA in vitro. Then, the transcription product was transfected into Vero cells by electroporation. At 48 h post-transfection, the transfected Vero cells were harvested, and passaging continued. A syncytium was not observed until the recombinant virus had passed through four passages. The presence of rBeau-H120(S1) was verified by the detection of the replaced ectodomain region of the H120 Spike gene using RT-PCR. Western blot analysis of rBeau-H120 (S1)-infected Vero cell lysates demonstrated that the nucleocapsid (N) protein was expressed, which implied that rBeau-H120(S1) could propagate in Vero cells. The TCIDs0 and EIDs0 data demonstrated that the titer levels of rBeau-H120(S1) reached 10(590+/-0.22)TCID50/mL and 10(6.13+/-0.23)EID50/mL in Vero cells and 9-day-old SPF chicken embryos, respectively. Protection studies showed that the percentage of antibody-positive chickens, which were vaccinated with rBeau-H120(S1) at 7 days after hatching, rose to 90% at 21 days post-inoculation. Inoculation provided an 85% rate of immune protection against a challenge of the virulent IBV M41 strain (103EID50/chicken). This recombinant virus constructed using reverse genetic techniques could be further developed as a novel genetic engineering vaccine against infectious bronchitis.

Mitogen-activated protein kinases (MAPKs) signal is one of the important ways in eukaryotic cell,which adjusts and controls the structure and function of the cell. MAPKs in eukaryotes include p38, ERK, JNK and ERK5, etc. With the deepening research,we found that the activation of p38, ERK, JNK signal pathways were closely related with osteoarthritis (OA) cartilage injury. MAPKs are the key signaling systems involved in the production of matrix metalloproteinases and the regulation of cartilage cell proliferation, apoptosis and differentiation. Expecially the matrix metalloproteinases can accelerate the degradation of articular cartilage. So it has been the new spot in pathogenesis of osteoarthritis study.

Objective To study the gene mutation of a Chinese family with Alport syndrome and to perform preimplantation genetic diagnosis before embryo implantation.Methods Next generation sequence analysis was done for checking COL4A3,COL4A4 and COL4A5 genes in the Alport syndrome family members.Array comparative genomic hybridization(CGH) was used to detect the embryos.Results A mutation c.2605G ＞ A was found and identified in COL4A5 gene of all of the Alport syndrome patients in the family,but COL4A3 and COL4A3 genes were normal in all of the detected people.After searching for the mutation database,the mutation c.2605G ＞ A of COL4A5 gene was related to the X-linked dominant Alport syndrome.Three embryos were detected by using the preimplantation genetic diagnosis.Among these embryos,there were two male and one female.One of the male embryos was chromosomal aneuploidy,which was 45,XY,-16 and the other was normal.This normal embryo was implanted,and after 20 weeks the prenatal amniocentesis diagnosis approved that the fetus was normal.Conclusions The mutation of COL4A5 gene (c.2605 G ＞ A) is the cause of Alport syndrome in this family,which indicates that next generation sequence analysis proves to be an accurate and rapid method to detect Alport syndrome disease.Meanwhile array CGH can be used to reduce birth rates as a useful preimplantation genetic diagnosis method.
