Objective To sonographically measure nuchal skin thickness(NT) and biparietal diameter/femur length (BPD/FL) for normal fetuses between 10 and 24 gestational weeks,screen abnormal cases then to culture fetal cells and chromosome analysis, diagnosis aneuploid chromosome deformed fetuses Methods Ultrosonic estimation of fetal gestation according to gestational sac or CRL or BPD/Fl and AC, measuring NT, BPD/Fl of 100 cases per gestational weeks, drawing normal curve of NT, making curve of 90 th and 10 th NT and BPD/Fl. Restropectively analysis 5 cases trisomy 21.Results The average of NT was 1 76mm between 10 and 13 gestational weeks. The average of NT was 3 52mm between14 and 24 gestational weeks. The value of 50th was 2 40~1 40 between14 and 24 gestational weeks.Conclusions If the value of NT is more than 90 percent of normal fetuses, and if BPD/FL ratio is morn than 90 percent of normal fetuses,the sensitivity of trisome 21 should increase.Combining factors as elderly and high risk parturition, the sensitivity of trisomy 21 is much more increasing.

Objective To determine whether peritoneal mesothelial cells express CD40 and to investigate potential mechanism by which CD40-CD40 ligand(CD40L) interaction may be involved in the inflammation of peritoneal membrane. Methods Rat peritoneal mesothelial cells (MC) were harvested from peritoneal cavity and maintained under defined in vitro conditions. Expression of CD40 on MC under normal culture or stimulation with interferon-?(IFN-?), tumor necrosis factor-?(TNF-?), interleukin(IL)-1 was examined by RT-PCR and FACS analysis. After activation with CD40 mAb, the expression of intercellular adhesion molecule-1 (ICAM-1) on MC was analyzed by FCAS. Results MC cultured in vitro expressed CD40 constitutively. The expression of CD40mRNA and CD40 protein up-regulated markedly following the stimulations with IFN-?, but not with IL-1, TNF-?. The expression of ICAM-1 on MC was significantly increased after activation of CD40 with IFN-? and CD40mAb. Conclusions MC functionally expresses CD40. The interaction of CD40 on MC and CD40L+ cells in peritoneal cavity may play an important role in peritoneal local defense and may be involved in the inflammation process of peritoneum.

AIM: To investigate the influence of dialysate on the cell morphology and the peritoneal membrane function in chronic peritoneal dialysis rats. METHODS: 40 SD rats were divided randomly into 4 groups. Except control group, other groups daily received infusion of 20 mL dialysate (4.25% dialysate(HG), 1.50% dialysate(LG), Riger's solution(RG)) respectively for 8 weeks. The peritoneal membrane function was investigated by peritoneal transport test, and the rat peritoneal mesothelial cells(PMCs)morphology was analyzed by the cell imprints. RESULTS: The intraperitoneal volume and net ultrafiltration in HG and LG groups were significantly lower, with D/P_(urea) significantly higher, and C_(urea) after 4 h of dialysis significantly lower than that in RG and control groups. The density of cell population from analysis of cell imprints in HG and LG groups was significantly lower, but the mean surface area were significantly larger than that in RG and control groups. These change had no difference between HG and LG group. Using the high glucose dialysate for 8 weeks significantly decreased the ultrafiltration volume ,which was significantly relate to the increasing of cell surface area (r=-0.896,P

OBJECTIVE:
To study the efficacy of treatment with microsurgery in combination with local injection of type A botulinum toxin for vocal process granuloma.
METHOD:
28 patients with vocal process granuloma received endotracheal intubation under general anesthesia. The lesion was removed with micro-scissor and CO2 laster under a self-retaining laryngoscope and microscope. The incision and mucous membrane surrounding the wound was closed with 8-0 absorbable suture. 4-point injection of botulinum toxin type A 8-15 u was then performed along the thyroarytenoid muscle and arytenoid muscle of the same side. Postoperative medication was administered based on disease causes.
RESULT:
All patients experienced vocal cord dyskinesia of the injected side 2-3 days after surgery. At 1 month after the surgery, wound healing was good in all the 28 patients, and the vocal cord movement was limited at the injected side. At 3 months, movement of the bilateral vocal cords was normal, and the vocal cord process mucosa was smooth. Patients were followed up for more than a year, and only one patient had recurrence in 2 months after surgery. The cure rate was 96. 4%.
CONCLUSION
Combination of laryngeal microsurgery and type A botulinum toxin local injection can shorten the treatment course of vocal process granuloma.

Background Diabetes is one of the risk factors that leads to corneal neuropathy.Silent signal regulatory factor 1 (Sirt1) plays an important role in glucose metabolism,lipid metabolism,regulation of insulin secretion and is closely related to the nervous system disease.The relationship between Sirt1 and diabetic corneal neuropathy is not fully understood.Objective This study was to detect the expression of Sirtl in cornea and trigeminal ganglion with type 1 diabetes model mice and explore the association of Sirt1 expression with diabetic corneal neuropathy.Methods Eight C57BL/6-Ins2Akita/J male mice and eight wild-type C57BL/6 male mice in the same litter were selected as type 1 diabetes model group and control group,respectively.The mice of two groups were sacrificed in overdose anesthesia method at 12-month old.Histological examination of cornea and trigeminal ganglion was performed using hematoxylin and eosin staining.Expression and localization of Sift1 protein in cornea and trigeminal ganglion were detected using immunohistochemistry.Western blot assay and fluorescine quantitative PCR were respectively used to quantitatively analyze the expression of Sirt1 protein and Sirt1 mRNA.Results Trigeminal ganglion cells were uneven in size and shape with the loosened cellular arrangement and disorder neurofibrosis alignment,and the corneal epithelial cells were less in the C57BL/6-Ins2Akita/J mice,but the trigeminal ganglion cells and corneal epithelial cells were normal in wild-type C57BL/6 mice.Immunochemisty exhibited that Sirtl protein was expressed mainly in corneal epithelium and the expression of Sirtl protein was stronger in the C57BL/6 mice than that in C57BL/6-Ins2Akita/J mice.Fluorescine quantitative PCR assay showed that the gray scale value of Sirt1 mRNA in cornea in C57BL/6-Ins2Akita/J mice was lower than that of the wild-type C57BL/6 mice(0.56±0.03 vs.0.98±0.13) with significant difference (t =5.853,P =0.010).Western blot showed that the expression of Sirt1 protein in cornea was lower in C57BL/6-Ins2Akita/J mice than that of the wild-type C57BL/6 mice(0.78±0.017 vs.1.300±0.012) with significant difference(t =33.140,P =0.001).However,no significant differences were seen in the gray scale value of Sirt1 mRNA(2.45±0.18 vs.2.51±0.22) (t=0.587,P=0.599) and protein level(1.100±0.015 vs.1.110±0.017) (t =0.430,P=0.709) in trigeminal ganglion tissues between C57BL/6-Ins2Akita/J mice and wide-type C57BL/6 mice.Conclusions The corneal nerve and structure is abnormal in 12-month-old C57BL/6-Ins2Akita/J mouse.Sirt1 is involved in the pathogenesis of diabetic keratoneuropathy,suggesting that it may be a potential target.
