Objective To study the expression and significance of P57KIP2 in complete mole(CM ) and partial mole(PM).Methods The expression of P57KIP2 in histology unequivocal 45 cases of CM and 30 cases of PM was detected by immunohistochemistry method.Results In the PMs,expression of P57kip2 was strongly and continuously(30/34),in the CMs,it was absent or weak expressed (5/45).The difference of P57K1P2 expression between PMs and CMs was statistically significant( P ＜ 0.05 ).Conclusion P57KIP2 immunostaining is a sensitive sign of partial moleand in differential diagnosis of PM from CM and it is deserving of clinical application.

OBJECTIVETo observe the clinical efficacy of BO's abdominal acupuncture for obese type-2 diabetes mellitus (T2DM).

METHODSSixty patients of obese T2DM were randomly divided into an acupuncture group and a medication group, 30 cases in each one. Patients in the medication group were treated with basic treatment combined with oral administration of regular antidiabetics, three weeks as one session. Patients in the acupuncture group, based on the medication group, were treated with abdominal acupuncture at Yinqiguiyuan [Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6), Guanguan (CV 4)], Fusiguan [Huaroumen (ST 24), Wailing (TE 5)], Tianshu (ST 25), Daheng (SP 15), Qixue (KI 13), etc.; the treatment was given three times per week, 3 weeks as one session. The systolic blood pressure (SBP), diastolic blood pressure (DBP), body weight, waist circumference (WC), hip circumference, body mass index (BI) were observed before and after treatment in the two groups, and fasting plasma glucose (FPG), fasting insulin (FINS), 2-hours postprandial blood glucose by oral glucose tolerance test (OGTT) and insulin, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C), HOMA-IR of insulin resistance index were calculated and adverge events were recorded.

RESULTSCompared before the treatment, SBP, WC, body weight, BMI, FPG, OG-TT2hBG, FINS, GTT2h insulin, HOMA-IR, TC and LDL-C in the acupuncture group were all significantly reduced (all P <0. 05), while FPG, OGTT2H insulin and TG were increased in the medication group (all P<0. 05)'. The differences of reducing SBP, WC, FPG, OGTT2H insulin, HOMA-IR, TC, TG and LDL-C were statistically significant between the two groups (all P<0. 05). The total effective rate was 93. 3% (28/30) in the acupuncture group, which was significantly superior to 23. 3% (7/30) in the medication group (P<0. 01).

CONCLUSIONBO's abdominal acupuncture has obvious clinical efficacy for obese type-2 diabetes mellitus, featuring in lowering blood pressure, reducing weight, decreasing blood glucose, im- proving insulin resistance and lowering lipid, which has no adverse effects and is worthy of clinical popularization and application.

Objective To study the DNA damage induced by dichloroacetic acid(DCA) and trichloroacetic acid(TCA) which are from drinking water disinfection by-products. Methods V79 cells and hepatocytes of mice were treated with DCA and TCA for 1 hour and then were tested by comet assay. After stained by EB, tail length of the cells were observed and counted under the fluorescence microscope. Results Both DCA and TCA could result in the increasing of average tail length of the treated cells whether they were V79 cells or hepatocytes of mice and the dose-response relationships were seen. Conclusion Both DCA and TCA can cause DNA damage of mammalian cells and this may be related to the carcinogenic mechanism. DCA and TCA belong to genetic carcinogens.

Objective:To establish a method for the determination of residual 5 heavy metal elements in single use and gravity feed infusion sets and intravenous infusion needles, including Cd, Cr, Cu, Sn and Pb. Methods:After the pre-preparation,the sample was dissolved in 1% nitrate. The 5 heavy metal elements in the sample solution were determined by inductively coupled plasma mass spec-trometry (ICP-MS). Results:Under the ICP-MS assay conditions, each element showed good linearity within the range of 0-50 ng· ml-1(r>0. 999 0). The average recoveries were within the range of 92%-116% and 1. 6%-2. 9%, respectively (RSD<3,n=9). Conclusion:The operation is simple and can meet the demand for the analysis of heavy metal elements in single use and gravity feed infusion sets and intravenous infusion needles.

The application of the multimedia combined with the PBL teaching model to the teaching of Gynaecology and Obstetrics is an open teaching model.It emphasizes that the class-teaching will be problem-based,and it can improve the students' initiative greatly and their enthusiasm as well.In this way,it can urge their desire to participate in the class-room activities and acquire knowledge.The method combined multimedia with PBL can also improve the teachers' teaching skills and their over-all clinical working abilities.

The application of standardized patient SP is the tendency of clinical medical education in China.Normative and effective SP training is the basis of good teaching quality of medical education.By introducing the experience about how to choose and train tandardized Pa-tients in medical teaching the author discusses its significances for the clinical education,with a view to further deepening SP follow—up to the teaching of medical and other clinical disciplines as well as providing a reference.

Circulating tumor cells (CTCs) play pivotal roles for monitoring the tumor metastasis and prognosis.The nanotechnology provides a favourable platform for CTCs detection,and enables CTCs to be more promising for practical application.Meanwhile,the nanoscale device by virtue of nanotechnology has broad application prospects in eliminating CTCs and offers a new direction in the field of anti-cancer.

Quantum dots (QD),a kind of nanocrystal,are made from Ⅱ-Ⅵ or Ⅲ-Ⅴ group elements.It has been reported that compared with current conventional fluorescent markers,QD have excellent optical properties such as strong fluorescence,photochemical stability and can be used for simultaneous multi-channel imaging.Meanwhile,as nanoparticle,QD can be easily surface modified with a variety of biological molecular and can reach cancer cells easily by penetrating the tumor angiogenesis.Therefore,QD have unique advantages in targeted real-time visual imaging of in vivo tumor and have great prospects in the individual diagnosis and treatment of tumor.However,the long-term biosafety after QD into the body still needs further study.
