Objective To investigate the clinical features and the efficient therapy of acute promyelocytic leukemia(APL)with high initial white blood cell(WBC)count.Methods The clinical features of 66 newly diagnosed APL patients with high initial WBC and 152 patients without high initial WBC from the First Affiliated Hospital of Soochow University between October 1993 and August 2006 were retrospectively analyzed.Additionally,66 patients with high WBC were divided into different groups according to the different induction therapy and the therapeutic effects were compared.Results The early death rate and the incidence of disseminated intravascular coagulation(DIC)and retinoic acid syndrome(RAS)were 30.3%,57.6% and 31.8% respectively for the group with high initial WBC,which were higher than the indexes of 7.2%,38.1% and 21.05% respectively for the group without high initial WBC(P

To explore the impact of acceleration load on the temporomandibularjoint in aviators and its clinical significance.617 aviators flying aircraft of different types without previous history of temporomandibularjoint disease were studied. Abnormal manifestations of the temporomandibularjointswere analysed. The incidence of temporomandibular joint symptoms was markedly higher in the fighter plane pilots than that in the transportation planegroup. Load induced by acceleration could be one of the main causative factors of temporomandibularjoint disorder.

[Summary] Patients with infertility and non-obese polycystic ovary syndrome ( PCOS) were treated with continuous subcutaneous pulse infusion of GnRH. After the treatment, a 32-year old female had regular menstrual cramps. Dominant follicle occurred after 2 months of treatment. The patient was pregnant and now has a healthy baby boy. It shows that the pulse infusion of GnRH could induce spontaneous ovulation and natural fertilization of the patients with non-obese PCOS.

Objective To evaluate the effect of intraoperative use of soluble hemostasis gauze on postoperative pel-vic infection in parturients undergoing cesarean section.Methods Data about cesarean section parturients in obstet-ric group(n=322)and gynaecology group (n =92)were surveyed by clinical follow-up and retrospective analysis method,obstetric group adopted bulk packing of gauze,gynaecology group adopted flat lay packing ,incidence of postoperative pelvic infection between parturients who used soluble hemostasis gauze with different packing meth-ods,as well as with different pieces were compared and analyzed.Results Pelvic infection rate in obstetric group and gynaecology group was 4.04%(13/322)and 0.00%(0/92)respectively,there was no significant difference be-tween two groups(P =0.082 ).In obstetric group,pelvic infection rate in parturients who used ≤3 pieces of solu-ble hemostasis gauze was 0,used >3 pieces was 11 .82%,there was significant difference between the two (P <0.001).Conclusion Rational use of soluble hemostasis gauze in caesarean operation can effectively avoid postopera-tive pelvic infection.

A novel type of carbon nanotube-coated Au nanoparticle and [bmim]BF4 composite modified glassy carbon electrode was fabricated by a layer-by-layer self-assembly technique. The electrochemical performance of acetaminophen (ACOP) on the modified electrode was investigated by cyclic voltammetry. The Nafion/GNPs/RTIL/MWNTs/GC electrode showed an excellent electrocatalytic activity for the oxidation of ACOP and accelerated electron transfer between the electrode and ACOP. For ACOP, the reversible electrochemical process was observed on the Nafion/GNPs/RTIL/MWNTs/GC electrode, while irreversible electrochemical process occurred on the GC electrode. For the Nafion/GNPs/RTIL/MWNTs/GC electrode, the anodic peak potential of ACOP was moved from 0.562 V to 0.413 V, with a potential drop of 149 mV. At the same time, the reduction peak potential was 0.384 V, and the potential difference was only 29 mV. It was shown that the modified electrode possessed higher electrocatalytic activity and more sensitive effect for the detection of ACOP than both MWNTs/GC electrode and GC electrode. The effects of the different experimental conditions on the electrochemical behaviors of ACOP were explored. Under the optimum conditions of preparation and experimental, the linear calibration curves of ACOP were obtained in a wide range of 2 x 10(-1) to 4.0 x 10(-4) mol x L(-1) with a correlation coefficient 0.999 2 and a detection limit of 2.6 x 10(-8) mol x L(-1) (the ratio of signal to noise, 3:1). The recovery rate was 97.9%-100.8%. This method can be used to determine ACOP in paracetamol tablets with satisfactory results.

Translationally controlled tumor protein (TCTP)is a small protein highly conserved in a variety of eukaryotic species.TCTP is overexpressed in various tumor cells and has been implicated in the regu-lation of cellular processes including apoptosis,DNA repair and drug resistance.By reviewing the recent pro-gress of TCTP research,TCTP is becoming an important regulator of DNA repair and a new molecular target for tumor therapy.

Objective To construct 2 recombinant plasmids carrying cassette chromosome recombinase C(ccrC)and ccrAB respectively and introduce the plasmids into methicillin-resistant Staphlococcus aureus(MRSA)strain 81/0432,and to observe the precise excision of Staphylococcal cassette chromosome mec(SCCmec)island from bacterial chromosome.Methods ccrC and ccrAB genes were amplified with chromosomal DNAs isolated from MRSA strains 81/0342 and N31S as PCR templates.We constructed recombinant plasmids pSR5C and pSR2AB by cloning ccrC and ccrAB genes into temperature-sensitive plasmid pYI3,after introducing them into MRSA strains 81/0432 and N315 by electroporation.PCR was performed to identify SCCmec excision from the bacterial chromosome.The transformants were serial passaged for 10 days,and then the drug resistance of these rransformants was detected by replica experiment.Results The fragment length of ccrC gene was 1.9 kb,smaller than the fragment length of ccrAB from N315.The recombinant plasmids of pSR5C and pSR2AB were successfully constructed.After these 2 recombinant plasmids were introduced into MRSA strain 81/0342,type-V SCCmec island was excised from the chromosome and formed a closed circular structure in the bacteria.However,type-Ⅱ SCCmec island could be excised only in N31S strain after the expression of pSR2AB.Replica experiment verified that transformed strains of 0342(pSR2AB),0342(pSR5C),and N315 (pSR2AB)were mostly susceptible to ceftizoxim or tobramycin after the excision of SCCmec island.Conclusion cciC could serve as a recombinase as ccrAB,which could mediate precise excision of SCCmec island from the chromosome of type-V MRSA strain.This study shows that type-V SCCmec island is widely disseminated between Staphylococcus aweus strains in community setting.
