1.Advances study of t(8;21) acute myeloid leukemia
Journal of Leukemia & Lymphoma 2010;19(6):380-382
One of the sub-types of acute myeloid leukemia(AML) characterized by the translocation of chromosome 8 to chromosome 21 and the expression of AML1-ET0 leukemia genesis fusion gene was proven to have better prognosis. Although remission rate has been improved by the combined chemotherapy primarily containing high dose cytarabine,it seems that target treatment with AML1-ET0 fusion gene/protein should finally cure this disease. In this article,we reviewed the relative studies and clinic target-treatment on AML1-ETO.

Objective To investigate the resistant status and to type the phenotype and plasmid profiles of prevalent gonococcal strains. Methods A total of 98 gonococcal strains isolated from 1998 to 1999 in Zhanjiang was identified systemically. The susceptibilities of 98 strains of gonococci to penicillin,tetracycline and ciprofloxacin were detected by agar dilution method. The β - lactamase production was tested by iodometric method. The plasmids were extracted by alkaline lysis technique. Results The prevalence of gonococcal strains resistant to penicillin, tetracycline and ciprofloxacin were 22.44% ,45.94% and 55.12% ,respectively. There were 6 positive strains for β - lactamase, accounting for 6.12% (6/98). The most common phenotypes were susceptiblePT、 CMRNGT、 CMRNGPT and TRNG, accounting for 43.86% ,23.46% ,10.20% and 10.20% ,respectively. The detection rate of plasmids were 91.84% .Among them, the percentages of 42.5 kb,39.5 kb,7.4 kb and 4.2 kb plasmids accounted for 11.22% ,41.82% ,59.16% and 67.32% ,respectively.There were 12 types of plasmid profiles(PP), the predominant types were 7.4kb+ 4.2kb and 39.5kb+ 7.4kb+ 4.2kb, accounting for 21.42% and 17.34% ,respectively. Conclusion The gonococcal strains resistant to ciprofloxacin are very high in Zhanjiang. The phenotype and plasmid profiles of the strains have characteristic distribution.

Objective To describe an appreciate operation method in the treatment of deformi-ties secondary to gluteal muscles and fascia contracture. Methods 25 cases of serious secondary de-formity of gluteal muscles and fascia contracture were treated by Z-plasty. The contracted fascia and scar were loosed and the skin around the wound was rearranged. Results The following-up time was from 6 months to 3 years with an average time of 1.6 years. All cases rehabilitated to normal or nearly normal in gait. Aesthetic results were also satisfactory. No recurrence was observed. Conclusion Re-arranging the contracted fascia with Z-plasty can extend the fascia and improve the movement of the hip joint. Besides, Z-plasty treatment of skin around the scar is benefit for the aesthetic result of the deformities, Z-plasty of contracted fascia and skin is an appreciate operation method in the treatment of deformities secondary to gluteal muscles and fascia contracture.

Objective To explore the effect of trimetazidine on myocardial structure injury induced by pyran adriamycin and to clarify the protective effect of trimetazidine on. the changes of myocardial structure and its mechanism.Methods 36 Wistar rats were randomly divided into control group,model group and treatment group. The rats in model group and treatment group were injected with pyran doxorubicin 2.5 mg·kg-1 (concentration 2 g·L-1 )by the caudal vein once a week.The rats in control group were injected with equivalent normal saline for 6 weeks.The rats in treatment group were intragastricly infused with trimetazidine 5.4 mg · kg · d-1 one day before making the model.The rats in control group and model group were injected with equivalent normal saline for 8 weeks.At the end of the experiment, the myocardial enzymes in serum of the rats in various groups were measured. The morphology of myocardium tissue was detected by light microscope and electron microscope. Results Compared with model group,the levels of myoglobin,troponin I and alanine transaminase (ALT)of the rats in treatment group were significantly decreased (P<0.05).Under light microscope the myocardium of the rats in model group arranged disorderly, the structure was severely damaged, emyocardial was seen, the myofilament was dissolved;the myocardium of the rats in treatment group arranged in order, the structure was nearly integrated,partial dissolution and fracture were found.Under electron microscope in model group the myocardial muscle bundle dissolved, fractured and disappeared, and the mitochondria was decreased,and the cytoplasmic matrix cavitation was seen;the cardiomyocytes sarcomeres of the rats in treatment group arranged in order,local myofilaments were reduced slightly, the surrounding mitochondria were oval and arranged in parallel between the muscle bundles.Conclusion Trimetazidine has protective effect on the cardiomyocyte injury caused by pyran adriamycin,and its mechanism may be related to decreasing the injury of mitochondria and myocytes.

To observe the effect of Weiyanxiao Granule (WG) in counteracting experimental gastric ulcer,acute lesion of gastric mucosa and to investigate its anti-inflammation and analgesic actions.Acute gastric ulcer models induced by stress or indomethacin, chronic gastric ulcer models induced by acetic acid and models with acute lesion of gastric mucosa induced by hydrochloride-ethanol or 0.2 mol?L -1 sodium hydroxide were used to observe the effect of WG in counteracting experimental gastric ulcer and acute lesion of gastric mucosa. Anti-inflammation action of WG was observed on mouse models with auricular swelling induced by dimethylbenzene, rat models with pedal swelling induced by white egg and rat models with granuloma induced by embedding tampon. Hot plate method and body-torsion test were used to observe the analgesic action of WG. As compared with the control group, WG 12.3?g?kg -1 and 24.6?g?kg -1 could decrease the ulcer index in rats with acute gastric ulcer (P

OBJECTIVE:To investigate the use of prophylactic use of antibiotics for special diagnosis and treatment in our hos-pital,and to provide reference for rational use of antibiotics. METHODS:The patients receiving special diagnosis and treatment were collected from our hospital during Jan.-Aug. 2016. The prophylactic application of antibiotics was analyzed statistically. RE-SULTS:Among 149 included patients,there were 62 cases of prophylactic use of antibiotics with utilization rate of 41.61%. Among 62 patients receiving antibiotics,5 cases were given medicine orally and others were via injection. Nine categories 18 types of antibiotics were used,involving 69 times;cephalosporin were used in 49 times(71.01%),among which top 3 types in the list of use sequence were cefodizime,cefotetan and cefazolin;prophylactic use of antibiotics was not found in angiography(including coronary artery) and stent implantation. Utilization rate of antibiotics for other diagnosis and treatment was more than 50%. The prophylactic use of antibiotics was complex in ureteroscopy and cystoscopy,shock wave lithotripsy;the selection of drug types started from the high level. There were 59 cases of single drug(95.16%)and 3 cases of two-drug(4.84%). Total of 41 cases were given medicine 0.5-2 h before surgery or at the beginning of anaesthesia (66.13%). Medication time of 18 cases was ≤24 h (29.03%);that of 11 cases was >24-48 h(17.74%). CONCLUSIONS:The prophylactic use of antibiotics is relatively standard in angiography(including coronary artery),stent implantation and implantation of peritoneal dialysis tube in our hospital. There are some problems during special diagnosis and treatment,such as the indication of drug delivery is not strict;the selection of drug types starts from the high level;medication timing is not suitable;medication course is excessively long.
