Objective To research the microinvasive therapy for intraspinal tumors resection and study the ways for spinal function protection. Methods Twenty-four cases were detected by MR. The intraspinal tumors located variously and the size of them ranging from 0.9 cm to 3.0 cm. All the tumors underwent resection via Key-hole on mono-lamina and the clinical data were analyzed. Results After tumor pathological examination,the cases of neurofibroma,neurinoma,and spinal meningioma were 9,12 and 3 cases. respectively. All the patient recovered and they walked within one week after operation. No recurrenced on MR examination after 3 months and no spinal tube destruction on CT examination after 6 months. Conclusion The microinvasive therapy via Key-hole on mono-lamina is benefic to the totally resection of intraspinal tumors and also benific to the spinal function protection.

Objective To study the characteristics and differential diagnosis of obsolete pulmonary tuberculosis accompanied withperipheral lung carcinoma.Methods CT findings of obsolete pulmonary tuberculosis accompanied with peripheral lung carcioma in 20 cases were retrospectively analysed.Results In 20 patients ,12 cases were diagnosed correctly because of them with typical CT findings of peripheral lung carcinoma,while 8 cases were misdiagnosed because of atypical CT findings of lung carcinoma.Conclusion Obsolete pulmonary tuberculosis accompained with peripheral lung carcinoma is common seen,atypical lung carcnioma is easily misdiagnosed.

Objective To study the frequency and relationship with gestational age of fetal nucleated red blood cell (NRBC) in maternal peripheral blood. Methods Samples of peripheral blood in 44 women of 6~40 gestational weeks were collected to enrich the fetal nucleated red blood cells by discontinuous density gradient centrifugation. The isolated cells were made smears and counted under the microscope. NRBCs were found and retrieved using a micromanipulator under a microscope for PCR amplification of Y chromosome specific DNA to determine fetal sex. Results NRBCs were found in 17 out of 44 maternal samples, distributing from 9 to 26 gestational weeks The highest frequency of NRBC was found in 11~20 gestational age which reached to 76.5%(13/17). The amount of detected NRBCs ranged from 5/7ml to 30/7ml. Y chromosome 149bp was found in 7 cases and not in the other 10, which agreed to the actual fetal sexes. Conclusion The appropriate time to make a prenatal diagnosis using fetal nucleated red blood cells is in 11~20 gestational age.

Objective [WT5”BZ] To evaluate the effects of glycyl glutamine (Gly Gln) on the small intestinal graft. [WT5”HZ]Methods [WT5”BZ] Ten outbrid pigs undergoing small bowel autotransplantation were randomly divided into 2 groups. In STPN group, the animals received standard TPN devoid of Gly Gln,and in GTPN group,the animals received isonitrogenous (0 3?g?kg -1 ?d -1 )and isocaloric (nonprotein calory:137 9?kJ?kg -1 ?d -1 ) TPN with 2% Gly Gln.Animals were fed for 28 days. [WT5”HZ]Results [WT5”BZ] At the end of TPN,the mucosal contents of Gln (1 14?0 20)??mol/g tissue wet weight, protein (101?22)?mg/g and the villous contents of DNA (3 84?0 39) and RNA (3 31?0 14),the graft villous height (308?52) ?m, surface area (0 154?0 019) mm 2 and mucosal thickness(665?72) ?m were significantly higher in the GTPN group than that in STPN group ( P

Objective:To observe the effects of Dyad Flow self-adhering flowable composite in the minimal invasive treatment of decid-uous molar caries.Methods:31 7 deciduous molars caries of 206 patients were randomly divided into 3 groups and treated by minimal invasive method,the cavities of the molars were filled with Dyad Flow self-adhering flowable composite(group A,n =1 07),traditional flowable composite and self-etching adhesive(group B,n =1 04)and glass ion(group C,n =1 06)respectively.The children were fol-lowed up for 1 and 2 years after treatment.Results:1 year after treatment the success rate(%)of group A,B and C was 95.3,96.77 and 91 .84(P >0.05);2 years after treatment 89.1 9,90.67 and 79.45(P >0.05),respectively.Conclusion:Dyad Flow self-adhe-ring flowable composite is effective in the treatment of deciduous molar caries.

To observe whether Naomai Yihao (NM) Capsule, a compound traditional Chinese herbal medicine for regulating the "sea of blood in brain", and bone marrow stromal stem cell (BMSC) transplantation could improve angiogenesis in focal cerebral ischemia in rats.

This study was designed to introduce basic components and sound-receiving effects of skin-hearing aid with transformer. This new device helped all people receive audible signals via skin, but the effects on discriminating phone were still not ideal.The experimental environment of the response of skin to audible signals was constructed for the theory research. The response on critical frequency and voltage among the transformer, the flat electrode and the skin has gotten in the experiment. It was discussed that the effect of the response of skin to audible signal between the key parts of device of hearing by skin with transformer and the skin. It was illustrated the practicability of skin hearing by sound-electricity converting.The skin-hearing aid, a low power consumption aid, was compared with traditional tools, such as hearing aid, electronic cochlea, and guide dogs, and the results proved the superiority of skin-hearing aid.

CXCR4 has long been considered as the unique receptor of CXCL12,and CXCL12/CXCR4 axis plays a prominent role in tumorigenesis.However,a novel receptor for CXCL12,named CXCR7,has been recently identified and also plays an important role in tumorigenesis.This review summarized current studies regarding the functions of CXCR4 and CXCR7 in cancer and the recent therapeutic approaches that target these receptors or their ligands.

Objective:To analyze the content of Pb, Cd, Cu, As and Hg in freeze-dried Rehmannia from different habitats by FAAS and double channels AFS. Methods:The contents of Pb,Cd and Cu in Rehmannia from different habitats were directly deter-mined by FAAS, while the contents of As and Hg were determined by double channels AFS after pretreated with HNO3-HClO4 . Re-sults:It was shown that each element had good linear relationship with the correlation coefficient above 0. 997 4. The average recovery was 97. 88%-100. 90% with RSD of 0. 019% -4. 20% (n=6). Meanwhile, the concentrations of 5 harmful elements and heavy met-als in 4 batches of 10 samples were higher than the limits described in Chinese pharmacopoeia. Conclusion:The results measured by the method are considered to be accurate, quick and easy to be operated. It can be used to determine heavy metals and harmful ele-ments in freeze-dried Rehmannia from different habitats.
