Objective To evaluate the effect of dose-rate and leaf position tolerance on the point dose in step-and-shoot intensity-modulated radiotherapy(IMRT). Methods IMRT plans of 2 prostate cancer patients were selected and recalculated for a water phantom.An ionization chamber was used to measure the dose of some points in the phantom at five nominal dose-rates:100 MU/min,200 MU/min,300 MU/min,400 MU/min and 500 MU/min.It was necessary to adiust the position of the water phantom to locate the ionization chamber in region where the dose gradient was very low in order to minimize the effect of dose gradient on the measured results.When measuring the effect of leaf position tolerance on point dose,the dose-rate was kept constant and the values of tolerance were 1 mm,2 mm,3 mm and 4 mm.This work was conducted on a Varian 23EX equipped with a Millennium 120-leaf multi-leat collimator(MLC).The treatment planning system was Varian Eclipse. Results As the dose-rate increased,the error between the measured dose and the calculated dose also enlarged.The difference between the maximum and the minimum was 1.2%.When MLC control system was working normally,tlle effect of leaf position tolerance on the measured point dose was very little and negligible. Conclusions The dose-rate must be selected suitably to ensure that the delivery can be finished in a short time with the radiobiological effect taking into account.It should be noted that the error between the measured dose and the calculated dose increases with the trend of inereasing more rapidly at higher dose rates.The value of leaf position tolerance should not be set too large,in order to minimize the difference between the measured dose and the planned dose in the region of steep gradient and find as early as possible when the multi-leaf collimator control system performs improperly.

Objective Combination of chemotherapy regimens and chemoradiotherapy to the curative effect of locally advanced nasopharyngeal carcinoma is unclear. The carcinoma radiotherapy adverse reaction and curative effect were investigated in nedaplatin plus fluorouracil in the same period radiotherapy(Group NF)compared with cisplatin(DDP)in the same period (Group DDP)in the treatment of locally advanced nasopharyngeal. Method Patients with locally advanced(ⅢandⅣB)nasopharyngeal carcinoma(NPC)in Sun yat?sen university cancer hospital were enrolled and divided into two groups:222 cases in the NF group and 165 cases in the DDP group. The adverse reaction,5?year progression?free survival(PFS)and overall survival(OS)for 5 years were evaluated in two groups. Results The 5?year PFS in the NF and DDP group was 85.13%and 82.42%,respectively, with no significant difference. The 5?year OS in the NF and DDP group was 85.58% and 82.42%,respectively, with no significant difference. The proportion of oral mucositis in the NF group was significantly lower than that in the DDP group. Conclusion Nedaplatin plus fluorouracil radiation therapy has similar curative effect ,adverse reaction with cisplatin plus the same radiation therapy in the treatment of locally advanced nasopharyngeal carcinoma.

Objective To analyze the clinical application of high?throughput gene sequencing technolo?gy and STR in chromosome karyotype analysis of the villus tissues of spontaneous abortion. Methods In 27 ca?ses of spontaneous abortion after pregnancy,classic cell of villus tissues culture and chromosomal karyotype anal?ysis,and high ?throughput gene sequencing technology and STR were performed,and then compared the analysis results of two methods. Results ( 1) The successful rate of cell of villus tissues culture and chromosomal karyo?type analysis was 85%( 23/27) ,of high?throughput gene sequencing technology and STR was 96%( 26/27) ,and the difference was not significant( P>0. 05) ( 2) In the 4 cases that failed in karyotype analysis,there were 3 ca?ses showed abnormal chromosomal number variation( CNV) in high?throughput gene sequencing technology and STR. ( 3) Of the 23 cases,chorionic villus was successfully cultured in 10 cases,abnormal karyotypes were iden?tified in 13 cases,the positive rate was 57%. Of the 26 cases,high?throughput gene sequencing technology and STR was successfully checked in 3 cases,abnormal CNV were identified in 23 cases,the positive rate was 85%, the difference was significant(χ2=6.387,P<0.05). (4)The rates of chromosomal number abnormality were 52%( 12/23) and 50% ( 13/26) of karyotype analysis and chromosome aberration detection,respectively. In 10 cases of normal cell culture karyotype,there were 7 cases in the presence of micro deletion / micro repetition de?tected by high?throughput gene sequencing technology and STR. Conclusion The method of massively parallel sequencing in chromosome analysis,compared with the method of cell of villus tissues culture and chromosome a?nalysis,can be accurate and quick,and has high successful rate in detecting the chromosome of non aneuploid and deletion/duplication abnormality,which can be a good complementary and alternative method of the classic cell of villus tissues culture and chromosome karyotype analysis.

OBJECTIVETo observe the protective effect on renal function of Chinese drugs combined with benazepril in patients with diabetic nephropathy (DN).
METHODSAdopting stratified randomized and controlled design, 108 patients with DN were assigned to two groups. Besides the same measures of diet regulation, exercise, education, hypoglycemic and symptomatic treatment applied, benazepril was administered to all patients, and Chinese drugs were given to patients in the treated group additionally. The treatment course was 3 months. The changes before and after treatment of symptoms and signs, 24-h urinary protein (24 hUpro), serum creatinine (SCr), serum creatinine clearance rate (CCr), blood urea nitrogen (BUN), plasma glucose (PG) and blood pressure (BP) were observed, and the time of dialysis therapy initiating was recorded.
RESULTSSCr and 24 hUpro decreased and CCr increased in the treated group significantly (P < 0.01), and the improvement were superior to that in the control group (P < 0.05 or P < 0.01), the renal living time in the treated group was longer than that in the control group, but no significant different in BUN, PG and BP was found between the two groups (P > 0.05).
CONCLUSIONThe treatment program of Chinese drugs combined with benazepril could obviously reduce the levels of SCr and 24 hUpro, increase CCr in patients with DN, and its effect in improving renal function is better than that of using benazepril alone.

OBJECTIVETo explore the possible mechanism of total flavonoids of Litsea coreana (TFLC) on reducing blood glucose level in rat with type 2 diabetes mellitus (T2DM).
METHODSMale SD rats of T2DM allocated in two groups were treated with 400 mg/kg TFLC or metformin respectively via gastrogavage for 6 weeks. Blood routine biochemical indices in rats were measured; pathology of rats' liver was examined with HE stain under transmission electron microscopy; levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in liver homogenate were determined, and the expression of protein tyrosine phosphatase 1B (PTP1B) in liver was detected using RT-PCR at the terminal of the experiment.
RESULTSBiochemical measuring showed that the glucose tolerance of rats after treatment was markedly improved in both groups. Meantime, levels of fast blood glucose (FBG), glycohemoglobin (HbA1c), fast blood insulin (FINS), free fatty acid (FFA), total cholesterol (TC), triglyceride (TG) and low density lipoprotein-cholesterol (LDL-C), as well as MDA level in liver were decreased, while levels of high density lipoprotein-cholesterol (HDL-C) in blood and SOD in liver were significantly increased in both groups after treatment, showing insignificant difference between two treatment groups. Light microscopic examination showed markedly fatty degeneration of liver, and electron microscopic examination found mitochondria swelling and endoplasmic reticulum breakage in liver of T2DM rats, but these changes were ameliorated to some extent after treatment. The elevated PTP1B expression in liver of T2DM rats was decreased in the TFLC treated group, but unchanged in the metformin treated group.
CONCLUSIONTFLC can significantly decrease the blood levels of glucose and lipid and ameliorate oxidation stress in liver; its mechanism of action in improving insulin resistance might be related with its suppression on PTP1B expression in rat's liver to enhance the insulin signaling pathway.
