Objective: To study the anti-tumor efficacy induced by antibodized tumor epitope PDTRP gene immunization. Methods: Three copies of tumor associate gene PDTRP from MUCI tandem repeats were designed and mimicked the conformation of MUCI by Insight Ⅱ . The ?lneo-PDTRP plasmid was further constructed, in which the PDTRP target gene was inserted into CDR3 of the ?1 -neo vector. The specific humoral and cellular immune responses towards to PDTRP were detected after intraspleen immunized Balb/c mice with "ylneo-PDTRP. And the immune protection assay was also done to observe whether the mice immunized with ?lneo-PDTRP could prolong the survival after tumor challenge. Results: The conformation of three copies of PDTRP mimicked the conformation of MUCI tandem repeats. The expression of ?lneo-PDTRP could be detected after in vitro transfect. The specific antibody against PDTRP epitope could be induced and increase to a higher titer after intraspleen injection with a ?lneo-PDTRP plasmid. And the specific proliferation and cytotox-ic function of lymphocyte were also increased. There is a significant survival from mice immunized with ?lneo-PDTRP a-gainst the 4T1-PDTRP tumor challenge. Conclusions: Gene immunization with ?lneo-PDTRP could elicit both humoral and cellular tumor specific immune response and had the protective effect.

Objective To describe an intelligent three-dimensional technique for automatic visualization of the fetal cranial mid-sagittal view to allow for the differential diagnosis of fetal midline anomalies.Methods Two hundred and twenty pregnant women with singleton pregnancies were imaged to display the mid-sagittal view of fetal head using a new 3D program (Smart MSP) developed by our team.Results The mid-sagittal view of the fetal head was successfully visualized in 190 normal cases (95％) and 18 abnormal cases (90％) by Smart MSP program.The total successful rate was 94.5％ (208/220).Conclusions Smart MSP is a novel and feasible method for the automatic visualization of fetal cranial midsagittal plane and may become a potential tool for routinely screening the fetal midline anomalies.

Objective To evaluate the clinical significance of prenatal ultrasonography in diagnosis of retroaortic left innominate vein ( LINV ) . Methods Thirty fetus with retroaortic LINV were involved , including 17 cases of isolated retroaortic LINV and 13 cases of complicated retroaortic LINV . Three-vessel and trachea ( 3VT ) view was focused in the routine second trimester ultrasound screening to observe whether LINV existing or not . And then the transducer was rotated to the fetal sagittal view to assess the relationship between LINV and aortic arch and the convergence of left subclavian vein and left internal jugular vein into the LINV . Results The characteristic feature of retroaortic LINV was the LINV converge into right superior vena cava ( SVC) under the aortic arch ,not above the aortic arch . The most important plane to detect the retroaortic LINV was the 3VT view ,which revealed the abnormal vein lying to the left of pulmonary artery . The abnormal vein then could be traced and revealed its connection with the right SVC beneath the aortic arch on the transverse plane inferior to the 3VT view and on the fetal sagittal plane . Conclusions The whole course of retroaortic LINV can be revealed by ultrasound prenatally ,which can not only account for the abnormal vein to the left of pulmonary artery on 3VT view ,but also play an important role in surgery decision and future cardiac intervention treatment .

The study is aimed to assess the genetic diversity and genetic relationship of 18 Sarcandra glabra resources from different populations,and guide parent selection of cross breeding between these resources. The molecular marker technique ISSR was used to investigate the genetic diversity of the 18 resources. Data was analyzed by POPGEN 32, and a cluster diagram was presented by UPGMA. One hundred and ninety-eight amplified fragments were obtained using 23 ISSR primers. One hundred and eighty-four polymorphic loci were identified. Nei's genetic diversity index (h) was 0.32, Shannon diversity index (I) was 0.485 4. The genetic similarity coefficient among the resources ranged from 0.383 8 to 0.878 8 in an average of 0.661 2. The genetic distance between sample S2 and sample S18 was the farthest, so as between sample S3 and sample S18 both Nei's genetic distance was 0.957 5, The genetic distance between sample S4 and sample S5 was the closest, the Nei's genetic distance was 0.129 2,and the sample S1, S2, S3, S7, S10 were significantly different from the others based on the clustering analysis, the three groups S2 vs S3, S2 vs S6, S2 vs S18 were the best parent group selection. There was a middle level of genetic differentiation in the resources. The genetic distance between resources gives useful information to guide parent selection of cross breeding.

OBJECTIVETo investigate the precise locations of the blood vessels and nerves surrounding the seminal vesicles (SV) in men and provide some anatomical evidence for SV-related minimally invasive surgery.

METHODSWe observed the courses and distribution of the blood vessels and nerves surrounding SVs and obtained the data for positioning the SV neuroplexes in 20 male pelvises.

RESULTSOne branch of the neuroplexes was distributed to the SVs bilaterally with the neurovascular bundles, (2.85 ± 0.18) cm from the median sulcus of the prostate (MSP), while another branch ran through the Denonvillier fascia behind the SV, (0.81 ± 0.06) cm from the MSP. The arterial SVs (ASV) originated from the inferior vesical artery and fell into 4 types, 55% going directly to the SVs as one branch, 15% running between the SV and the ampulla of the deferent duct as another branch, 25% downward as 2 branches to the SV and between the SV and the ampulla of the deferent duct respectively, and 5% as the other ASVs. The shortest distance from the ASV through the prostatic neuroplexus to the posterior SV was (1.08 ± 0.09) cm.

CONCLUSIONIn SV resection, neuroplexus injury can be reduced with a bilateral distance of < 2.85 cm and a posterior distance of < 0.81 cm from the MSP, and so can bleeding by vascular ligation between the SV and the ampulla of the deferent duct.

A 57-year-old man was admitted to the hospital for a 7-year progressively spreading plaques involving the entire body surface, and multiple irregularly sized red nodules and infiltrated patches on the face, trunk and limbs. Histopathological examination showed pleomorphic tumor cells diffusely dis-persed throughout the dennis, giving an appearance of low proliferation. Some cells with cytoplasmic pro-cesses appeared multiangular in shape, lmmunohistochemically, tumor cells were negative for CDla or S-100, but positive for CD45, FXIIIa, CDl4, MHC- Ⅱ, CD68 and lysozyme with extracellular interstitial expression. Ultrastructurally, the cells exhibited cytoplasmic processes and irregularly sized nuclei; no Birbeck granules were observed. Vesicules of low electron-density were seen diffusely in cytoplasm and extracellular matrix. The case is herein diagnosed as cutaneous non-Langerhans cell histiocytosis, which presents with a chronically invasive clinical course. These cells may develop from immature dermal dendritic cells.

OBJECTIVETo explore potency material bases of Xuebijing (XBJ) formula, and to analyze its effects at the molecular network level.

METHODSTotally 16 sepsis-related targets were selected and classified into three categories such as inflammation, immune, and coagulation referring to biological roles. Then molecular database of chemical compositions in XBJ formula were constructed to explore mutual actions with inflammation, immune, and coagulation targets.

RESULTSDanshen root and safflower, with more effector molecules with immune and coagulation targets, have extensive anticoagulation and anti-inflammation effects. The former 10 molecules with better mutual actions with sepsis targets were sequenced as tryptophane, danshensu, gallic acid, salvianolic acid D, protocatechuic acid, salvianolic acid A, danshensu C, vanillic acid, rosmarinic acid, phenylalanine. There existed two phenomena in XBJ formula as follows. One component had stronger actions with multi-targets, for example, danshensu had actions with 13 targets. Meanwhile, different components acted on the same target protein, for example, 8 molecules acted with MD-2.

CONCLUSIONXBJ formula had certain potential synergistic effects with sepsis targets, which could provide certain referential roles for findina new type anti-septic drugs.

OBJECTIVETo observe the effect of Shenshuaining Granule (SG) combined telmisartan on serum creatinine (SCr) levels and urinary albumin contents in diabetic nephropathy (DN) patients, and to explore its efficacy.

METHODSTotally 204 DN patients were recruited, and further assigned to 3 groups, i.e., the early DN group, the clinical stage of DN with normal renal function group, the clinical stage of DN with insufficient renal function group. Patients in the same group were randomly allocated to the telmisartan treatment group, the SG treatment group, and the combination of SG and telmisartan treatment group, 68 in each group. Patients in the telmisartan treatment group took telmisartan tablet, 80 mg per day, once daily. Those in the SG treatment group took SG, 5 g each time, 3 times per day. Those in the combination of SG and telmisartan treatment group took telmisartan tablet (80 mg per day, once daily) and SG (5 g each time, 3 times per day). The therapeutic course for all was 3 successive months. SCr levels, serum urea nitrogen (BUN),24 h urine microalbumin (24 h U-MA) were detected before and after treatment. Results In three different treatment groups, 24 h U-MA decreased after treatment in the telmisartan treatment group; SCr and BUN decreased after treatment in the SG treatment group; and 24 h U-MA, SCr and BUN decreased after treatment in the combination of SG and telmisartan treatment group (P<0.05). In the clinical stage of DN with insufficient renal function group, SCr obviously increased after treatment in the telmisartan treatment group (P <0. 05). In the 3 DN stages, SCr and 24 h U-MA obviously decreased in the combination of SG and telmisartan treatment group, when compared with the telmisartan treatment group and the SG treatment group (P<0.05). Compared with the telmisartan treatment group, SCr and BUN obviously decreased in the SG treatment group, but 24 h U-MA quantitation obviously increased (P<0.05). BUN obviously decreased in the combination of SG and telmisartan treatment group (P<0. 05).

CONCLUSIONThe combination of SG and telmisartan could decrease urinary albumin, and stabilize SCr levels.
