Objective: To establish a flow-injection chemiluminescence method for the determination of doxorubicin, epirubicin and mitoxantrone and study its reaction mechanism. Methods: In alkaline medium, chemiluminescence of luminol-potassium permanganate system could be inhibited obviously by anthracycline antibiotics. Combined with flow-injection technique, a new chemiluminescence method for determining the anthracycline antibiotics was set up. The chemiluminescence mechanism of the luminol-potassium permanganate system was also discussed. Results: Under optimal conditions, the good linear ranges of doxorubicin, epirubicin and mitoxantrone were 5.0×10-9-1.0×10 -6 g/mL, 1.0×10-9-1.0×10-5 g/mL and 3×10-9-1.0×10-6 g/mL, respectively. The detection limits of doxorubicin, epirubicin and mitoxantrone were 3.0×10-9 g/mL, 5.0×10-6 g/mL and 2.0×10-9 g/mL, respectively. During eleven repeated inter-day and intra-day precision tests of 1.0×10-6 g/mL samples, the relative standard deviations corresponded to reference values of 3.0% ,2.8% and 2.1%. Conclusion: The developed method is sensitive, accurate, rapid and of low cost. It can be applied to determine doxorubicin hydrochloride, epirubicin hydrochloride and mitoxantrone hydrochloride in injection preparations.

Objective To explore the clinical effects of different regimens of letrozole in the treatment of PCOS in patients with infertility.Methods A total of 87 cases of PCOS infertility were selected as the research subjects.The patients were divided into the group A(44 cases of menstrual cycle 3rd~7th day oral letrozole 5mg/d), the group B 43 cases(3D of the menstrual cycle to take a one-time oral letrozole 20mg),ultrasound monitoring was used in the treatment process,when the maximum follicle diameter greater than or equal to 18mm,HCG intramuscular injection of human chorionic 10 000IU(HCG).The changes of endocrine hormones in the two groups were compared and the effect of ovulation induction was compared.Results Menstruation the fifth day serum T,FSH,LH,between the two groups had no statistically significant differences (P>0.05 ).The serum E2 in the group B [(106.1 ± 43.2)nmol/L]was lower than that in the group A[(183.2 ±69.4)nmol/L](t=6.204,P<0.05).Injection of HCG on the same day,the serum T,FSH and E2 between the group A and group B showed no significant differences(P>0.05),serum LH level in group B[(31.1 ±9.2)IU/L]was lower than that in the group A[(34.6 ±8.9)IU/L](t=2.010,P<0.05 ).In group B,the endometrial thickness,the number of mature follicles,the ovulation rate,the pregnancy rate within 12 months were (0.94 ±0.11)mm,(1.46 ±0.41),95.35%,35.26% respectively,which were significantly higher than those of the group A[(0.83 ±0.13)mm,(1.14 ±0.25),70.45%,13.64%](t=4.256,t=4.407,χ2 =9.445,4.398,all P<0.05).Conclusion The 3rd day at menstrual cycle,taking a single oral dose of letrozole 20mg program is favor of an early lowering E2 levels,and can promote follicular maturation and development,improve the pregnancy rate in patients with PCOS.

Objective To investigate the relationship between the apoptosis,expressions of Bcl-2 and Bax protein in perihematomal brain regions of rats and neurologic dysfunctions after intracerebral hemorrhage (ICH). Methods Seventy Sprague-Dawley rats were divided randomly into two groups:an experimental group and a control group.A model of ICH was established by injection of 0.5 U bacterial collagenaseⅦinto the caudate nucleus in the rats.Neurological impairment was evaluated at 6 h,12 h,24 h,48 h,72 h,7 d and 14 d after 1CH,respectively, before the rats were sacrificed.TUNEL method was used to detect apoptosis,and SP method to detect expressions of Bcl-2 and Bax protein in the perihematomal brain tissues.Results Neurological impairment occurred in all the rats after ICH,and peaked at 48 h after ICH.The apoptosis and expressions of Bcl-2 and Bax protein were peaked at 48 h,6 h and 48 h after ICH,respectively.Conclusion The degree of the neurological impairment after ICH is parallel to that of the apoptosis.Apoptosis may play an important role in neurological impairment after ICH.

Currently, competition in the market of health service of our country is very fierce. In this circumstance, realization of military hospital's development aim-focuse on people, leading position in technology-to provide better service armyman is depend on economic foundation. To increase economic benefit of hospital, it is necessary to intensify management of cost accounting first, in which cost accounting of clinical department is of especial importance. In this article, we probe into the significance, content, method and problems of cost accounting in clinical department of military hospital.
