Objectives To observe the effect of inhibition of transforming growth factor (TGF)?1 on the growth and aggression of colon cancer cells by RNA interference. Methods HCT116 colon cancer cells were transfected with small interfering dsRNA (siRNA), the effect of the inhibition of TGF?1 was tested by semi-quantitative RT-PCR, and changes in cell cycle distribution were analyzed by flow cylometry, the ability of aggression was detected by soft agar colony assay. Results The inhibition of the expression of TGF?1 was significantly detected after the transfection of siRNA against TGF?1, which induced the increase of S phase by 59.0%-82. 5% and decrease in G2 phase, colony assay further demonstrated that siRNA against TGF?1 led to a significant reduction in colony formation as compared with the control group. Conclusions The present data suggested that the expression of TGF?1 was conveniently and rapidly blocked by siRNA transfection, and this may lead to the cell cycle arrest and inhibition of the growth and tumorigenesis of colon cells.

Objective To isolate and observe Pityrosporum yeasts from a patient with onychomycosis. Methods The involved nail specimens were investigated by means of culture, pathological and scanning electron microscopic examination and 20% KOH preparation. Results Physical examination showed that each finger and toe nail appeared brownish black, rough and thick, some of the fore part of the nail plate detached from the nail bed. Fingernail specimen's culture results showed that Trichophyton rubrum grew on Sabouraud's dextrose agar and Pityrosporum ovale grew on the medium containing rapeseed oil. The pathological examination revealed P.ovale yeast involvement in the fissure of the nail plate. Under the scanning electron microscopy, a lot of P.ovale yeasts with characteristic collarette structure inserted in the nail tissue was noticed. In the 20% KOH preparations of nail incubated at 56℃for 1h and stained with Quink Parker ink, spores and hyphae were identified morphologically with P.ovale and T.rubrum respectively. The patient received intermittent pulse therapy with itraconazole, the color of the nails became much brighter 1 to 2 months after the fourth cycle of therapy, but no further improvement was observed afterwards. P.ovale and T.rubrum grew again 6 months after treatment when the clippings of the fingernail were cultured. Conclusion This is the first document of onychomycosis related with P.ovale in China.

Objective To study the morphological,biologic response of cultured human keratin ocytes to Candida albicans and the molecular mechanism.Methods ①A yeast form of C.albicans was added t o a monolayer of keratinocytes.The adherent organisms were observed by scanning and transmission electron mi-croscope at different incubation periods.Boiled C.albicans and latex beads of a similar size(3.2?m)were also inoculated for comparison.②The effect of supernatant from the co-culture of keratinocytes with inta ct C.albicans on keratinocyte growth was measured by the fluorescence intensity and cell count.③Keratinocytes were incubated with C.albicans or latex beads,and the level of cytok ine in the keratinocytes and supernatant were measured with enzyme -linked im munosorbent assay kits.Results①The number of adherent C.albicans increased with the lapse of time,whi le boiled C.albicans did not adhere at all.Many latex bead s adhered to the keratinocytes,and were then easily phagocytised.Fibril -like structu res stretched from the keratinocyte s adhered to the organisms or latex beads.②The conditioned medium of 50%concen tration significantly promote cell growth,while that with boiled C.albicans or latex beads moderately stimulate d keratinocyte growth.③Ker-atinocytes treated with intact C.albicans had significantly higher level of IL-1?in the supernatant but lower in the cell extract.Both TGF -?and bFGF increased either in the medi a or in the extract.Conclusion These results suggest that keratinocytes have non -specific phagocytic activ ity.C.albicans are able to adhere to ker-atinocytes and stimulate the release of various cytokines from keratinocytes,which may induce an inflammatory reaction and cell growth.

Objective To study the anemia status and genotype of thalassemia in preschool children in Shenzhen. Methods 658 preschool with anemia hospitalized in Shenzhen Longgang Maternal and Child Health Hospital from October 2012 to September 2015 were screened by complete blood analysis . The most common mutations of thalassemia genotype (17 β thalassemia genotype mutation,3 α thalassemia genotype mutation and 3α thalassemia genotype absence change) in Chinese population were detected. Results All cases have microcytic hypochromic anemia. 426 cases were identified to be thalassemia (64.7%). 23 genotypes and 13 gene mutation type were detected. The most common genotype type were SEA/αα(46%),β654/βN(15%),β41?42/βN(12.7%). And the most common allele gene mutation type were SEA (49.1%),IVS?Ⅱ?654( C→T)(14.4%),CD41?42(?TTCT)(12.4%) re?spectively. MCV and MCH of thalassemia children was significantly lower than that of children diagnosed as without thalassemia. The differences of RBC,Hb,MCV,MCH,MCHC,RBC?SD between the two groups were statistical?ly significant. Conclusion The proportion of thalassemia among preschool anemia children in Shenzhen area was high,and it is necessary to strengthen the local thalassemia prevention and decrease anemia effect on preschool children′s health.

The authors used a microvascular corrosion cast/scanning electron microscopy (SEM) technique to study the microvascular bed of the muscles of the medial pterygoid and masseter in two normal babies. The cast were prepared by perfusing the microvascular vessels with methyl methacrylate. Under SEM, the patterns of branches of the arteriole are: 1. tree like ramifications; 2. symmetrical branching; 3. fine plexiform branching. Moreover, the casts of arterial and venous vessels showed on their surfaces the typical imprint of the endothelial lining. Therefore, the venous vessels could be easily identified by the round nuclei of the endothelial cells of the venous vessels. On the other side, arteries and arterioles displayed spindle shaped nuclear imprints, oriented along the direction of the vessel. The morphological and functional characterization of the imprint of the precapillary sphincter and the two-grade anastomoses of the arcade arteries. The diameter of the capillary casts (mean?SE) was 5.6?1.9?m. Two or three capillaries join together to form a postcapillary venules, sometimes a single capillary reaches a major venous trunk was observed. These structural features were considered to play an important physiological role in the microcirculation in skeletal muscle.
