Objective To investigate the influence of indomethacin to the unite treatment effect on chronic phase myeloid leukemia (CML-CP) with interferon alpha-2b (IFNα-2b) and low dose cytarabine (LD-Ara-C).Methods 22 CML-CP patients were randomly divided into two groups.Control groups (10 cases) injected with IFNα-2b (3 million units),injection frequency was q.o.d,the duration of treatment was about 3-18 months,cytarabine (Ara-C) by slowly intravenous driped (30 mg/d).In this treatment schedule,every course of treatment sustained 10 days,and with a 2 weeks interval.During this process,patients in treatment group were treated with hydroxyl urea only when their WBC in peripheral blood exceed 20×109/L,otherwise,discontinue it.Treatment group (12 cases),on the first day of treatment with IFNα-2b and Ara-C,added indomethacin (25 mg) through oral administration,the frequency was t.i.d.During treatment in the two group,the end point of observation was completely hematology ease,at the same time,these indicators in the two groups needed to be compared,the time when WBC begin to fall,the time when WBC fall to normal range,the time when immature cells returned to normal,the time which complete hematological remission and the highest temperature of patients after IFNα-2b was subcutaneous injected.Results The time when WBC begin to fall in treatment group was (4.2±2.7) d,and the time was (5.0±2.5) d in control group (t =0.714,P > 0.05).In treatment group,the time when WBC fall to normal range was(10.0±4.5) d,and the time was (12.0±4.5) d in control group (t =1.036,P > 0.05).The time when immature cells returned to normal in treatment group was (14.2±4.8) d,and the time was (19.0±3.6) d in control group (t =2.609,P < 0.02).The time which complete hematological remission was achieved in control group was (45.8±5.6) d,but it was (53.9±10.5) d in control group (t =2.314,· P < 0.05).Meanwhile,the fever degree after IFNα-2b was subcutaneous injected obviously achieved improvement in treatment group (x2 =12.041,P < 0.005).Conclusion The advantage of indomethacin to the unite treatment with IFNα-2b and LD-Ara-C on CML mainly lays in which cound alleviated the adverse reaction such as flu-like of IFN,and more,there are synergy effect in antagonist CML.

Based on the strain breeding theory and metabolic engineering theory, A high-yield mutant of Lactobacillus Thermophilus ATCC8317 was obtained through the compound inducements by the original Acetic acid-Sodium acetate plate and the productivity increased 210%.The best media components included saccharifying corn,malt powder 30g/L,peptone 5g/L.Based on the variety of specific cell growth rate and specific L-lactic acid production rate at different temperatures, the strategy of temperature control was obtained. The total product of L-lactic acid reached 135g/L besides the rate of glucose consumed and the average L-lactic acid productivity were up to 95% and 2.25g/(L?h) respectively.

OBJECTIVE To analyze the pathogenic bacteria distribution and drug resistance in inpatients of burn department,and instruct clinical application of antibiotics reasonably.METHODS Pathogenic bacteria were isolated from inpatients of burn department from 2003 to 2006.K-B slip diffusion method was taken to carry out the sensitive test.Rate of drug resistance of the pathogenic bacteria was analyzed.RESULTS Totally 1325 strains were isolated,among them 846 strains were Gram-negative bacteria,464 strains were Gram-positive ones,and 15 strains were fungi.The percentage of these three groups was 63.85%,35.02% and 1.13%,respectively.The main strains of the Gram-negative bacteria were Pseudomonas aeruginosa,Escherichia coli,Acinetobacter baumannii,Enterobacter cloacae and Klebsiella pneumoniae,and that of the Gram-positive bacteria were Staphylococcus aureus,Enterococcus and Staphylococcus epidermidis.The major strain of fungi was Candida albicans.The pathogenic bacteria tested showed high drug resistance.The detection rate of the meticillin-resistanct S.aureus(MRSA) was 82.12%.The detection rate of the ESBLs from the K.pneumoniae and the E.coli was 60.17% and 41.89%.CONCLUSIONS It was showed that the major pathogenic bacteria infected of the inpatients of burn department are Gram-negative bacteria.The pathogenic bacteria are the multidrug-resistant ones.Enhanced monitoring on pathogenic bacteria distribution and drug resistance analyses among inpatients of burn department could benefit for the guide of clinical rational administration and depression of multidrug-resistant bacteria.

OBJECTIVETo study the efficacy and safety of multimodal prevention of postoperative venous thromboembolism for hip fractures.
METHODSFrom March 2009 to July 2011, preoperatively, patients were assigned to two groups on the basis of an assessment of their risk factors. One hundred and twelve patients were considered to be low risk, involving 47 males and 65 females,with an average age of (72.40 +/- 13.29) years ranging from 42 to 88,and were managed with aspirin (100 mg once daily for 14 days) as well as intermittent gasing compression devices. Twenty-six patients were considered to be high risk, involving 12 males and 14 females with an average age of (78.50 +/- 12.76) years ranging from 65 to 84,and were managed with low-molecular-weight heparin (0.4 ml,subcutaneous injection once daily for 14 days) and intermittent gasing compression. All patients were underwent Doppler ultrasonography within 24 hours before hospital discharge. All patients were followed-up for 3 months postoperatively. The incidence of deep venous thrombosis of lower limb, pulmonary embolism, gastrointestinal hemorrhage were recorded.
RESULTSOverall, there were no fatal pulmonary embolism, 1 case of symptomatic pulmonary emboli in low risk group, and none were detected in the high-risk group. Deep venous thrombosis was detected in association with 6 (6.25%) of the 112 procedures in the low-risk group and 2 (7.69%) of the 26 operations in the high-risk group. Paitents were selected in opened reduction and internal fixation, the quantity of bleeding, decrease of hemoglobin, hematoma rate, and gastrointestinal hemorrhage rate of low risk group were (538.10 +/- 390.20) ml, (30 +/- 19) g/L, 0, and 1 (1.03%) respectively; those of the high-risk group were (585.95 +/- 403.96) mL, (32 +/- 20) g/L,1 (4.76%), (4.76%), there were no significant different between the two groups, all P > 0.05.
CONCLUSIONThere were no statistic significances between the aspirin as well as intermittent gasing compression devices and the low-molecular-weight heparin and intermittent gasing compression in preventing venous thromboembolism (VTE) in postoperative postoperative venous thromboembolism for hip fractures. However, there are potential advantages to reduce complications of bleeding and cardiovascular disease. Multimodal prevention of postoperative venous thromboembolism can protect postoperative patients with hip fractures.

OBJECTIVETo investigate the diagnosis and treatment of ovotesticular disorders of sex development (DSD) in children.
METHODSWe reviewed the clinical data of 9 cases of ovotesticular DSD admitted in our department from 1988 to 2007.
RESULTSThe patients ranged in age from 9 months to 9 years, 7 raised as males and 2 as females. As for the karyotype, 4 cases were 46,XX, 2 were 46,XX/46,XY, 1 was 46,XY, and the other 2 had no karyotype data. All of them presented with obscure external genitalia: perineal or penoscrotal hypospadias with or without cryptorchidism in males and hypertrophy of the clitoris in females. They were diagnosed with ovotesticular DSD by gonad biopsy and underwent genitoplasty.
CONCLUSIONThe gender assignment of the ovotesticular DSD patient was chiefly based on the development of external genitalia, dominant gonad, karyotype and the parent's will. Laparoscopic technology is recommended in gonad biopsy and orchiopexy during the treatment of ovotesticular DSD.
