ObjectiveTo investigate the effects of vascular endothelial growth factor (VEGF) and dexamethasone on mRNA expressions of surfactant protein B (SP-B) and transforming growth factor-β1 (TGF-β1) of type Ⅱ alveolar epithelial cell (AECⅡ). MethodsAECⅡ were isolated and purified from fetal rat lung tissues,then cultured with different dose of VEGF (25,50 and 100 ng/ml) and dexamethasone (25,50,100 and 200 nmol/ml).The mRNA levels of SP-B and TGF-β1 were detected by real-time quantitative polymerase chain reaction (RT-PCR) and expression of TGF-β1 protein was detected by immunocytochemistry.ANOVAor q-test wasappliedtocompare the difference among groups.ResultsCompared with control group,SP-B mRNA levels in 25 ng/ml VEGF group and 25,50,100 and 200 nmol/ml dexamethasone groups were higher (13.500±3.172,3.547±0.690,5.219±0.782,3.493±0.335,and 3.981 ± 1.133 vs 1.001 ± 0.059,q=-5.286,-4.943,- 7.228,- 9.906 and - 3.525 respectively,P<0.05) ; TGF-β1 mRNA expression of 25 ng/ml VEGF group,50,100 and 200 nmol/ml dexamethasone group was lower (0.451 ± 0.078,0.579±0.019,0.422 ± 0.020 and 0.769 ± 0.025 vs 1.019±0.226,q=4.110,3.356,4.551 and 1.901 respectively,P<0.05) ; other groups had no significant differences compared with control group (P>0.05).Immunocytochemistry showed that the positive rate of TGF-β1 expression in 25 ng/ml VEGF,50,100 and 200 nmol/ml dexamethasone group was 23%,26%,22% and 29%,respectively,while in the control group,the expression of TGF-β1 was positive in most of the AECⅡ (80%).ConclusionsBoth VEGF and dexamethasone could increase the expression of SP-B at mRNA level at appropriate concentrations.At the same time,the expression of TGF-β1 is inhibited.It is suggested that both VEGF and dexamethasone might increase the mRNA expression of SP-B by inhibiting the expression of TGF-β1.

Objective To analyze the clinical application of high?throughput gene sequencing technolo?gy and STR in chromosome karyotype analysis of the villus tissues of spontaneous abortion. Methods In 27 ca?ses of spontaneous abortion after pregnancy,classic cell of villus tissues culture and chromosomal karyotype anal?ysis,and high ?throughput gene sequencing technology and STR were performed,and then compared the analysis results of two methods. Results ( 1) The successful rate of cell of villus tissues culture and chromosomal karyo?type analysis was 85%( 23/27) ,of high?throughput gene sequencing technology and STR was 96%( 26/27) ,and the difference was not significant( P>0. 05) ( 2) In the 4 cases that failed in karyotype analysis,there were 3 ca?ses showed abnormal chromosomal number variation( CNV) in high?throughput gene sequencing technology and STR. ( 3) Of the 23 cases,chorionic villus was successfully cultured in 10 cases,abnormal karyotypes were iden?tified in 13 cases,the positive rate was 57%. Of the 26 cases,high?throughput gene sequencing technology and STR was successfully checked in 3 cases,abnormal CNV were identified in 23 cases,the positive rate was 85%, the difference was significant(χ2=6.387,P<0.05). (4)The rates of chromosomal number abnormality were 52%( 12/23) and 50% ( 13/26) of karyotype analysis and chromosome aberration detection,respectively. In 10 cases of normal cell culture karyotype,there were 7 cases in the presence of micro deletion / micro repetition de?tected by high?throughput gene sequencing technology and STR. Conclusion The method of massively parallel sequencing in chromosome analysis,compared with the method of cell of villus tissues culture and chromosome a?nalysis,can be accurate and quick,and has high successful rate in detecting the chromosome of non aneuploid and deletion/duplication abnormality,which can be a good complementary and alternative method of the classic cell of villus tissues culture and chromosome karyotype analysis.

Journal of Zhejiang University. Science. B 2006;7(4):314-319
Bentonite is a kind of natural clay with good exchanging ability. By exchanging its interlamellar cations with various soluble cations, such as quaternary ammonium cations and inorganic metal ions, the properties of natural bentonite can be greatly improved. In this study, hexadecyltrimethylammonium bromide (HDTMA), CaCl(2), MgCl(2), FeCl(3), AlCl(3) were used as organic and inorganic pillared materials respectively to produce several kinds of Ca-, Mg-, Fe-, Al-organo pillared bentonites. Sorption of reactive red X-3B on them was studied to determine their potential application as sorbents in wastewater treatment. The results showed that these pillared bentonites had much improved sorption properties, and that the dye solutions' pH value had some effect on the performance of these inorgano-organo pillared bentonites. Isotherms of reactive X-3B on these pillared bentonites suggested a Langmuir-type sorption mechanism.

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.

OBJECTIVETo investigate the tongue manifestation features of sexually transmitted and intravenous drug use spread HIV infected population in Xinjiang.
METHODSRecruited were 990 HIV infected subjects in Xinjiang from May 2011 to March 2012, who were assigned to the intravenous drug use spread HIV infected (498 cases) and the sexually transmitted (492 cases). By using tongue figure shoot combined with analyses of experts, tongue manifestations were analyzed and compared between the sexually transmitted and the intravenous drug use spread from four aspects, i.e., the tongue color, the tongue shape, the fur color, and the fur property.
RESULTSCompared with the sexually transmitted population, red tongue, fissured tongue, yellow fur, thick fur, eroded fur, deficiency of fur fluid were more often seen, showing statistical difference (P < 0.05). Compared with the intravenous drug use spread population, pale tongue, white fur, and thin fur were more often seen, showing statistical difference (P < 0.05).
CONCLUSIONSThe tongue manifestations of the intravenous drug use spread HIV population reflected inner exuberance of evil toxin and heat impairing qi and yin. Compared with the intravenous drug use spread population, the attack of HIV infection was more hiding in the sexually transmitted population, with milder internal injury. Their Wei-qi was not damaged and no obvious change occurred in the tongue figure.
