Cancer immunotherapy is a new approach to cancer treatment. Dendritic cells, the most potent antigen-presenting cells found in humans, have attracted a lot of researches. However, dendritic cells are insufficient to cross-present self-antigens in-vivo. To improve the dendritic cells' antigen-presenting capabilities and the anti-tumor effect, in vitro preparation of dendritic cell vaccine and combination with pro-apoptotic treatments such as chemotherapy are being used.

Apigenin is a plant flavonoid which has various biological activities and pharmacological effects including anti-tumor, antioxidant, anti-inflammatory, sedative and so on, particularly in the anti-tumor areas. It can inhibit proliferation, invasion, metastasis and angiogenesis of tumor cells. In addition, it can also induce apoptosis and enhance chemotherapy sensitivity.

Objective To explore clinical significance of constriction of fetal ductus arteriosus diagnosed by echocardiography.Methods Seventy-one cases with constriction of fetal ductus arteriosus (DA) and one fetus with premature closure of DA were detected by fetal echocardiography among 2380 singleton fetuses.The echocardiographic characteristics and clinical outcomes were reviewed and analyzed.Results Of 71 cases with constriction of fetal DA,58 cases were found with right heart enlargement,12 cases with tricuspid regurgitation,8 cases with arrhythmia and 1 case with pericardial effusion.The echocardiographic characteristics showed narrowed diameter of DA,dilatation of pulmonary artery and descending aorta was also noted,DA was markedly curved.The peak systolic velocity(PSV) and enddiastolic velocity(EDV) in the ductus arteriosus measured by pulsed Doppler echocardiography increased (PSV≥ 180 cm/s,EDV≥35 cm/s).All cases were confirmed normal by neonate echocardiography.Conclusions Prenatal echocardiography plays important role in diagnosis of constriction of fetal DA.Early diagnosis and intimate follow-up can direct clinician to offer suitable consultation for parents and management for fetuses.

Interactions between hepatocellular carcinoma (HCC) cells and the tumor stromal microenvironment have profound effects on tumor growth,epithelial-mesenchymal transition (EMT),invasion and metastasis.Activated hepatic stellate cells (HSCs) are the major subtype of stromal cells in the liver tumor microenvironment.HCC cells can induce the activation of HSCs during carcinogenesis,while activated HSCs promote HCC cells growth and migration through secreting growth factors,inducing angiogenesis and immune suppression.Bidirectional interactions between HCC cells and HSCs may function as an ＂amplification loop＂ to further enhance metastatic growth in the liver.In this review,we summarized the most recent data from the research on HSCs and its relationship with HCC.

Foreign student education is an important task in medical colleges and universities.Clinical neurology teaching is very difficult because of its complex discipline.Neurologists in the First Affiliated Hospital of Chongqing Medical University summarized and analyzed the common problems including the training of teachers' ability to use language,teaching of basic subjects,clinical skills training,promotion of patients' compliance and implementation of regular tests so as to provide references for improving the quality of neurology teaching.

Objective To study the anatomical characteristic of nanophthalmos with ultrasonography and its clinical significance. Methods Forty-four nanophthalmic eyes (22 patients) and 200 normal eyes (100 persons) were included. A series of ocular parameters, including ocular axial length, angle between trabeculum and iris,thickness of lens and sclera.and vitreous cavity length were measured with ultrasound A-scan and ultrasound biomicroscopy. The refractive status was examined with dioptometry. Results The ocular axial length[(15. 95±0. 76)mm] and vitreous cavity length [(8. 48±0. 90)mm] were shorter, the lens [(4. 9±0. 53)mm] and sclera [(0. 917±0. 119)mm] were thicker in nanophthalmic eyes than those of normal eyes( P <0.01). The relative position of lens (0.312±0.09) was more forward, and the angle between trabeculum and iris (11. 41 ±7. 63 ) was narrower in nanophthalmic eyes, compared with normal eyes( P <0. 01). The hyperopia of nanophthalmic eyes was negatively correlated with the ocular axial length ( r = -0.806) and vitreous cavity length ( r = - 0. 663) ( P <0. 01). Conclusions Nanophthalmos was characterized by short ocular axial length, thick lens and sclera.and narrow anterior chamber angle. The thickness of sclera and the angle between trabeculum and iris measured with ultrasound biomicroscopy could provide a solid indication of the treatment to the complication of angle closure glaucoma.

Objective To investigate the correlation between high myopia and MMP-2 in aqueous humor (AH), by comparing the protein level of MMP-2 in AH from patients with cataract combined with high myopia and with emmetropia. Design Experimental study. Participants 30 AH samples of patients with age-related cataract. Methods AH samples were collected from the patients with age-related cataract during phacoemulsification, including 15 AH samples from patients combined with high myopia (experimental group) and 15 AH samples from patients with emmetropia (control group). The expression of pro-MMP-2 and MMP-2 in AH were ana-lyzed by Western blot technique. Main Outcome Measures The gray value of MMP-2 protein band detected by Western blot. Results The level of pro MMP-2 was statistically higher than that of MMP-2 in experimental group (430.4±57.3 versus 294.5±35.2, t=10.400, P= 0.000) and control group (402.8±57.7 versus 280.3±49.7, t=8.400, P=0.000). There was no statistically difference in the level of pro-MMP-2(t=1.320, P=0.200)and MMP-2 (t=0.900,P=0.375) between the two groups. Conclusions No abnormal expression of MMP-2 was detected in AH from patients with high myopia, according to this study based on limited samples. Pro-MMP-2 was the main form of MMP-2 in AH of patients with cataract combined with high myopia or emmetropia, which possessed potential ability of transferring into form of active MMP-2.

The etiology of rotated maxillary central incisor is unclear, but it has a clear familial tendency. Except for the environmental factors, gene expression directly influences craniofacial growth and the types of malocclusion deformity. In this article, a case of 180° rotated left maxillary central incisor of a male with family history of the deformity was reported. Relevant literature was also reviewed.
