Objective To compare the whole-body equivalent doses from volumetric modulated arc therapy (VMAT) and static intensity-modulated radiotherapy (IMRT) for patients with cervical cancer.Methods Nine patients with cervical cancer admitted to our hospital in 2014 were included in this study.Both VMAT and IMRT were planned for each patient.Each patient's personal dose equivalent (Hp (10)) was measured using thermoluminescent dosimeters placed at the xiphoid process and glabella during IMRT and VMAT.The whole-body equivalent doses were estimated based on the results measured at the xiphoid process and compared between the VMAT and IMRT techniques.The paired t test was used for difference analysis.Results The Hp (10) values measured at the xiphoid process and glabella of every patient were lower for VMAT than for IMRT.At a prescribed dose of 50 Gy,if the mean Hp (10) values measured at the xiphoid process were considered to represent the whole-body equivalent doses,the whole-body equivalent doses for VMAT and IMRT were 364 mSv and 538 mSv,respectively.Conclusions VMAT results in a lower whole-body equivalent dose to patients compared with IMRT.The decreased whole-body equivalent dose delivered by VMAT may reduce the likelihood of a radiation-induced secondary malignancy.

Objective To investigate the influence of murine cytomegalovirus on the expansion of CD+CD25+ Foxp3+ regulatory T cell (Treg) and the activation of CD4+ CD25+Foxp3 - effector T cell (TE) in vivo. Methods Forty-two BALB/c mice were intraperitoneally inoculated with appropriate amount ofMCMV Smith strain for establishing the model of infection, another 42 mice served as mocked-infected con-trois. Day 28 post MCMV infection was determined to be the demarcation point of the acute and chronic in- fection based on the viral load of major visceral organs. On day 1,3, 7, 14, 28, 45 and 60 post infection, splenocytes were prepared by means of routine method. The proportions of CD4+CD25+ Foxp3+Treg and CD4+CD25+Foxp3- activated TE in T lymphocyte were measured by flow cytometry. Results The propor- tion of CD+CD25+ Foxp3+ T cells in T lymphocytes was persistently suppressed since day 7 post infection, and fell to the lowest level on day 28 post infection (P <0.01), then zoomed and reached the peak value on day 60 post infection (P < 0.05). CD4+CD25+ Foxp3 - TE proportion was up to the highest on day 3 post infection(P < 0. 01), then suppressed and in significantly lower level since day 45 post infection (P < 0.05). Treg/CD+TE ratio was in lower level on day 3 to 14 post infection(P <0.05) ; but on day 45 and day 60 post infection Treg/CD+ TE ratio was markedly increased (P < 0.05). Conclusion MCMV infec- tion can increase the CD+CD25+Foxp3+ Treg proportion, and inhibit CD4+T cells activation in chronic in- fection phase, which is likely to suppress the function of antiviral immunity in the infected host to cause a persistent latent infection.

To establish a method of directional differentiation and efficient production of neurons from embryonic stem cells (ES cells) in vitro, based on the 4-/4+ protocol described by Bain, a new method was established to induce ES cells differentiating into neurons by means of three-step differentiation using all-trans retinoic acid (ATRA) combined with astrocyte-conditioned medium (ACM) in Vitro. The totipotency of ES cells was identified by observation of cells' morphology and formations of teratoma in immunocompromised mice. The cells' differentiation was evaluated continuously by the detection of the specific cellular markers of neural stem cells, neurons and astrocytes, including nestin, NSE and GFAP using immunohistochemistry assay. The NSE positive cells' ratio of the differentiated cells was determined by flow cytometry. It was found that the transparent circular clusters surrounding embryoid bodies induced with combining induction protocol formed just after 24 h and gradually enlarged later. This phenomenon could not be observed in EBs induced only by ATRA. The NSE positive cells' ratio in the cells induced with ATRA and ACM was higher than that of the cells induced by ATRA at different time points of differentiation, and finally reached up to 73.5% among the total differentiated population. It was concluded that ES cells could be induced into neurons with high purity and yield by means of inducing method combining with ATRA and ACM.

Objective To investigate the value of combined detection of multi-tumor markers in the diagnosis of primary hepatocellular carcinoma (HCC) and to establish the discriminant equation. Methods Using a protein chip, 12 tumor markers in the serum from 98 patients with HCC and 67 patients with benign liver diseasewho had been admitted to Daping Hospital from November 2003 to April 2006, and 46 healthy individuals during he same period were analyzed. A discriminant equation was established to discriminate primary HCC from benign liver diseases. All the data were processed by variance analysis and chi-square test. Results The positive rates of the tumor markers were 89% (87/98) in patients with primary HCC, 19% (13/67) in patients with benign liver disease and 4% (2/46) in healthy individuals. There was statistical difference in the serum level of alpha-fetoprotein (AFP), eareinoembryonic antigen (CEA), ferritin (FER), CA19-9 and CA125 among the 3 groups (F =59.530, 40.472, 31.708, 75. 897, 153.066, P <0.05). Combined detection of AFP, CEA, FER, CA19-9 and CA125 improved the diagnostic accordance rate to 89%, which was significandy higher than the diagnostic accordance rate (64%) when only AFP was detected (X2 = 16.362, P <0.05). The accuracy of the discriminant equation was 90%. Conclusions Combined detection of multi-tumor markers is superior to AFP detection. Combined detection of multi-tumor markers can be used in screening of the HCC patients in HCC high risk population and in the early diagnosis of primary HCC.
