ObjectiveTo explore ultrasonographic featurs of nuchal skin of normal fetus in its thickness and changes.MethodsThe thickness of nuchal skin of 900 normal fetal was measured by abdominal ultrasound with 7.5 MHz probe.ResultsThe nuchal skin only displayed whole layer before pregnant 27 weeks. After pregnant 27 weeks, the derma and subderma layer was distinguishable, the whole thickness of nuchal skin was ( 1.18 ? 0.05 )mm (10 weeks) to ( 6.01 ? 0.46 )mm (40 weeks) in normal fetus. All layers of nuchal skin were increased proportionally with gestation [r= 0.973 (whole layer), P 0.05 ).Conclusions The abnomal chromosome of fetus could be sifted by the thickness of nuchal skin and the character of sonographic image. It′s a useful diagnostic method for eugenics.

Objective To evaluate the clinical value of TVCDU in the diagnosis and followed-up of the gestational choriocarcinoma . Methods TVCDU and related clinical data of 21 patients suffered from the gestational choriocarcinoma during May 2003 and July 2004 were restrospectively analysed.Results The sonographic manifestations of choriocarcinoma could be classified into 5 types;(1)The uterine became larger than the normal , the local myometrium was changed into irregular non-echo region which was full of blood testified by CDFI(Color Doppler flow image);(2)The myometrium became nonhomogenity with plenty of blood flow , the resistance index ( RI ) was 0.25~0.47;(3)The abnormal echo emerged in the uterine cavity was not apparent boundary to the myometrium; (4)Neoplasm in the adnexa had relatively obvious blood flow,RI was about 0.4;(5)There was no abnormal echo in pelvic organ. The relation ship between sonographies and HCG first determined was complex. However,the lesions reduced, RI descended during the treatment of chemical therapy, so did the HCG .Conclusion TVCDU plays an important role in the differential diagnosis and the evaluation of curative effects of choriocarcinoma during the course of followed- up.

Objective:To observe whether the HPV16L1VLP Hela-cell binding-inhibition experiment can assess the immune-protective activities of HPV16L1 antibody in HPV16 prophylactic vaccine or other fields.Methods:C57BL/6 mice were divided into three groups,including pcDNAL1 plasmid,HPV16L1VLP protein,pcDNA3.1 plasmid.Each group of mice was immunized intramuscularly or subcutaneously with certain above antigens,accompanying three times and interval 3 weeks.After 14 days of 3 rd immunization,take blood to make serum for immunochemistry.Results:Hela cell neutralized by the serum IgG of experimental mice can be stained negatively,while the cells of control and non-inoculation groups can be stained positively (brown-yellow color).Conclusion:HPV16LIVLP Hela-cell binding-inhibition assay may be the better way to reflect the neutralizing-protective activities of HPV16L1 antibody in many fields including HPV16 prophylactic vaccine.

Tumor infiltrating lymphocytes(TILs) were isolated by enzymatic digestion and discontinuous gradient centrifugation from 8 human advanced tumors (4 stomach carcinoma, 2 liver cancer, 1 non-small-cell lung carcinoma and 1 colon cancer). These cells were cultured in complete RPMI 1640 medium supplemented with l000U/ml of rhIL2 for 4-6 weeks, till the cell number reach over l09/total, reinfused to the same patients i.v. meanwhile, the patients received 105U of rhIL2 i.m for 5 days. One week before and one month after TIL infusion periphery blood from the patients was collected and the mononuclear cells were isolated. Cytotoxicity against a panel of tumor cell targets by MTT colorometric assay and lymphocyte phenotype by two-color flow cytometry were mornitored. The results showed that there was significant increase in the killing ability to the tested tumor targets to different extent, especially the killing to the target cells which shared the same histological type with the patients tumor.

The purpose of this article is to d iscuss the meaning and the method of testing the ER/PR.We use the anti-ER、 ant i-PR monoclonal antibody SP method to detect the ER/PR in 26 cases of the endome trial cancinoma endometrium、23 cases of the atypical hyperplasia and 22 cases o f the normal endometrium respectively.The result shows that the SP method to t est the ER/PR has different result in carcinoma、atypical hyperplasia and normal endometrium.The expression of ER/PR in carcinoma is distinctly lower than th at in the atypical hyperplasia and normal endometrium.There is no significant d ifferent between the atypical hyperplasia and normal endometrium of the expressi on of ER/PR.However,there are significant different in the ER.PR expressions b e tween normal endometrium and endometrial careinoma,and between atypical hyperpla sia and endometrial careinoma,reflecfing the special biological action of the tu mor.SP method to test the expression of ER/PR has some special meaning to estim ate the prognosis and supervises the treatment of the carcinoma of the uterine.

Objective To assess the efficacy and safety of intensive pulse light (IPL) device for facial rejuvenation and the treatment of hyperpigmented lesions, facial telangiectasias, acne vulgaris and hair removal. Methods One hundred females who claim to improve their skin texture, hair re-moval and patients with hyperpigmented lesions, facial telangiectasias and acne vulgaris were treated with IPL device. Patients received five treatments with the time interval of 3 weeks to 1 month. Pho-tographs were assessed 1 month after the last treatment. Results For facial skin texture, the total im-provement were scored 100 %. For hyperpigmented lesions and facial telangiectasias, the total im-provement reached to 90%. For ache vulgaris, the total improvement reached to 75 %. For hair re-moval, the total improvement was 95 %. Conclusion The IPL device is an effective and safe modality for the improvement of skin texture, hyperpigmented lesions, facial telangiectasias and hair removal, and a novel modality for the treatment of acne vulgaris.

Objective To investigate the change trend of liver function indicators in different types of hyperlipidemia patients. Methods From July 2014 to July 2015 ,a total of 2571 patients with hyperlipidemia and 1063 normal people(control group) were collected in this research.All patients with hyperlipidemia were divided into the hypercholesterolemia group (high TC group ,n=258) ,hypertriglyceridemia group (high TG group ,n=859) and mixed type hyperlipidemia group(n=282) ,low high-density lipo-protein cholesterol group(low HDL-c group ,n=1172).The liver function indicators of total protein (TP) ,albumin (ALB) ,alanine aminotransferase(ALT ) ,aspartate aminotransferase (AST ) ,AST/ALT and globulin (GLB ) were measured in each group. Results The TP and ALB levels in the high TC group ,mixed group and low HDL group were significantly decreased compared with the control group ,the difference was statistically significant (P<0.05).The ALT ,AST ,AST/ALT and GLB levels in the four hyperlipidemia groups had different degrees of increase as compared with the control group ,the difference was statistically signifi-cant(P<0.05).The TP and ALB levels in the mixed group and the low HDL group were significantly lower than those in the high TG group and high TC group ,the difference was statistically significant (P<0.05).The ALT level in the low HDL group was sig-nificantly higher than that in the other three groups ,the difference was statistically significant (P<0.05).The AST/ALT level in the mixed group was significantly higher than the other three groups (P<0.05).The GLB level in the high TC group was signifi-cantly higher than the other 3 groups with statistical difference (P<0.05).Conclusion Blood lipid increase may induce the liver function injury.The detection of liver function indicators in the patients with hyperlipidemia will contribute to the early detection and treatment of fatty liver.
