Objective To observe the effect of external use of Curcuma oil on the hyperplasia of mammary glands in rats and explore the mechanism. Methods Sixty female Wistar rats were randomly divided into following groups:normal con-trol group, model control group, Sanjierubi plaster group, low-, medium- and high-dose curcuma oil emulsion groups ( n=10 each).The models of hyperplasia of mammary glands were established by intramuscular injection of estradiol benzoate and proges-terone into the medial part of the rat hind limb.Different doses of medicines were given for 4 consecutive weeks.Enzyme-linked im-munosorbent assay, HE staining and immunohistochemistry were used to investigate the action mechanism of curcuma oil emulsion against mammary gland hyperplasia. Results Curcuma oil emulsion had preventive and therapeutic effects on the hyperplasia of mammary glands.The diameter of breasts was significantly reduced, the body weight restored, serum estradiol, follicle-stimulating hormone and prolactin levels profoundly decreased, progesterone, testosterone and luteinizing hormone levels markedly increased and the number and diameter of lobular acini obviously reduced in high-dose curcuma oil emulsion group when compared with those in model control group (P<0.05 or P<0.01). Conclusion Curcuma oil emulsion can remarkably improve the disturb-ance of serum hormones and inhibit the occurrence of hyperplasia of mammary glands.

Vascular disrupting agents (VDAs) have presented a new kind of anti-cancer drug in recent years. VDAs take advantage of the weakness of established tumor endothelial cells and their supporting structures. In contrast to anti-angiogenic therapy, which inhibits the outgrowth of new blood vessels, vascular targeting treatments selectively attack the existing tumor vasculature. Here we summarized the anti-tumor activities, mechanisms and clinical applications of small molecule VDAs.

AIMTo validate the abundance of Interleukin 8 receptor beta (IL-8Rbeta) mRNA in single human neutrophil.
METHODSHuman neutrophils were isolated and purified from volunteers, total RNA was extracted and a regular RT-PCR aiming at IL-8Rbeta mRNA was performed to ascertain its expression profile in human neutrophils and optimize the reaction conditions for the following single-cell RT-PCR procedures. Subsequently, single neutrophil or the cellular content was harvested to conduct reverse transcription and two-round PCR with the same primer pairs used before. Serial dilution of single neutrophil cDNA pool was carried out at the same time with the exact two-round PCR followed. The specificity of this single-cell RT-PCR procedure was verified by the BamHI restriction endonuclease digestion on the final cDNA products.
RESULTSRegular RT-PCR indicated IL-8Rbeta mRNA expression in human neutrophils. While single-cell RT-PCR was sensitive enough to detect trace IL-8Rbeta mRNA as predicted cDNA product could be amplified from a 10 000 times diluted intracellular specimen from single neutrophil, which indicated an abundant expression of this mRNA in human neutrophil. Moreover, BamHI digestion on the final cDNA product clarified the specificity of this single-cell RT-PCR procedure.
CONCLUSIONThis simplified semi-quantitative single-cell RT-PCR procedure specifically confirmed that IL-8Rbeta mRNA was highly expressed in human neutrophil, which also provided the possibility of comparing mRNA abundance at single cell level.

Objective To elucidate the features of clinicopathology and mutation in Fabry disease complicated with thin basement membrane nephropathy (TBMN), and to investigate the kindred. Methods Data of clinicopathology and gene mutation of a female patient of Fabry disease complicated with TBMN admitted to the Department of Nephro]ogy in our hospital were analyzed. Members of her kindred were investigated simultaneously. Results Proband was a 41-year-old Chinese woman who presented syndrome of Fabry disease and TBMN including angiokeratomas, chronic pain, tinnitus, vertigo, left ventricular hypertrophy and nephropathy as proteinuria, microscopic hematuria and hypertension. A percutaneous renal biopsy was performed on the proband, which was consistent with FSGS and vaculization of podocytes by light microscopy.Electron microscopy showed concentric lamellated inclusions in some podocytes. Diffuse thinning of glomerular basement membrane (GBM) with a mean thickness of (216±31) nm was found. The diagnosis of TBMN with suspected Fabry disease was identified. Family screening showed that her daughter had microscopic hematuria, tinnitus and neuropathic pain. One of her sisters only had microscopic hematuria. The activity of α-galacsidase A (α-Gal A )enzyme in the proband and her daughter was 33 units and 75 units respectively (the normal range is 100 to 500 units). They all carried the novel GLA mutation 1208 ins 21 bp and COL4A3 SNP c: 3627G>A(p:M1209I). While her sister who only had microscopic hematuria just carried the variant of COL4A3 gene-c:3627G >A (p:M1209I), and had the normal activity of α-Gal A with no mutation of GLA.Conclusion TBMN should be considered in the patients of Fabry disease with the condition of benign familial hematuria.

OBJECTIVETo find an effective operative procedure against reflux after esophagogastric anastomosis with mucosal valve.
METHODSFour hundred and sixty-four patients with esophageal or cardiac cancer were randomly divided into three groups according to anastomosis modes. Group A underwent esophagogastric anastomosis with mucosal valve (175 cases), group B with mechanical stapler (151 cases) and group C one layer anastomosis with handcraft suture (138 cases). The gastroesophageal reflux index (GERI) was examined by isotope,and 24 h esophageal pH was also monitored. The esophageal motor function was compared among three groups.
RESULTSThe reflux rates were 0, 33.3%, and 6.7% in group A, B, C respectively. The esophageal motor function and the 24 h esophageal pH monitoring indicated that the various indexes were approaching to the normal level in group A, but the various indexes in group B and C were significantly different from the normal values (P< 0.05).
CONCLUSIONThe esophagogastric anastomosis with mucosal valve has better antireflux effect and can prevent the reflux esophagitis after esophageal or cardiac cancer eradication.
