Objective To explore a suitable mode of prenatal ultrasound diagnosis of fetal malformations with early neonatal surgical treatment. Methods Nine fetus with surgical malformations diagnosed prenatally by ultrasound in our hospital from Mar. 1998 to Dec. 2000 were analysed. Results There were two cases diagnosed in the second trimester, 7 in the third trimester, including 1 duodeneal atresia with annular pancreas, 1 abdominal wall defect, 1 congenital diaphragmatic hernia, 1 huge omphalocele, 1 high imperforate anus, 4 hydronephrosis (2 mild and 2 severe). Six cases were operated in neonatal period, two were treated conservatively, and one did induced abortion. All cases recovered except 1 death. Conclusions The mode of prenatal ultrasound diagnosis with surgery in early neonatal period is a suitable way in China before the fetal surgery is applied. It is important to make effort to increase sensitivity of sonographic diagnosis of fetal malformation and to get early treatment in perinatal period.

Unleashed growth of gross healthcare expenses has emerged a major headache for public administration of countries at large.In China as well,such a rapid growth is incurred mostly by overtreatment due to irrational healthcare compensation.Against this background,it is highly significant to have a brand new insight into over-treatment in China' s viewpoint,and to further study the role of an improved mechanism for primary healthcare compensation for the purpose of curbing over-treatment.These efforts will help improve the primary healthcare service and realize goals of the ongoing health reform.

Adenomyomatosis of the gallbladder (GAM) is an acquired,benign proliferative lesion of the gallbladder which is characterized by mucosal proliferation with invaginations and diverticula penetrating into the thickened muscular layer (Rokitansky-Aschoff sinuses).GAM consists of 3 types:diffuse,segmental and fundus GAM.There is no specific presentation of GAM,and computed tomography is helpful for the diagnosis of this disease.From July 2010 to May 2013,16 patients with fundus GAM were admitted to the Second People's Hospital of Wuxi.Rokitansky-Aschoff sinuses and calotte sign at the thickened muscular layer of the fundus of the gallbladder are the typical presentation of the fundus GAM.Enhanced computed tomography examination is of great importance for the diagnosis of the fundus GAM.

OBJECTIVETo study the effect of Ti-TiO2 nanotubes with different diameters on the adhesion of fibroblast and osteoblast, and to find which diameter was more favorable for cells' respective adhesion.

METHODSPure titanium sheets were polished and then anodized at different potentials for 1 h with Ti as anode and Pt as cathode. TiO2 nanotubes formed at 1, 5, 10 and 20 V potentials served as experimental groups and polished pure titanium served as control group. Field emission scanning electron microscopy (Fe-SEM) was used to analyze the surface topography. Stained nucleus with Hoechst33342 were used to measure the cell adhesion. The cell shape on the sample surface were analyzed with Fe-SEM.

RESULTSTiO2 nanotube array of different inner diameters from 15 nm to 100 nm were grown on titanium sheets by anodization at potentials from 1 to 20 V. At 30, 60 and 120 min, fibroblast adhesion at nanotubes anodized at 5 V was (141 ± 9), (388 ± 14) and (489 ± 15) respectively, significantly less than any other nanotube surface at the same time (P < 0.01). Nanotubes anodized at 20 V had the least inhibitory effect for fibroblast adhesion with a number of (579 ± 14) at 120 min, and the cell shape was also inhibited. At 30, 60 and 120 min, osteoblast had a significant better adhesion on nanotubes formed at 5 V than it did on any other surface at the same time (P < 0.01), except the control group at 30 min, with the adhesion number of (198 ± 10), (431 ± 10) and (501 ± 10) respectively, and osteoblast had a abundant spread on nanotubes formed at 5 V; while osteoblast adhesion on nanotubes anodized at 20 V was (152 ± 11), (403 ± 9) and (465 ± 12) respectively, less than on any other nanotube surface within the same time (P < 0.05), and the cell shape on the surface changed to be more elongate.

CONCLUSIONSFibroblast adhesion is inhabited more or less on Ti-TiO2 nanotubes of different diameters. Nanotubes formed at 5 V have the most osteoblast adhesion, and inhibit fibroblast adhesion.

AIM: To evaluate the expression of iNOS mRNA in different invasion ability colon carcinoma cell strains. METHODS: MTT was used to detect the growth and reproduction of colon cancer cell strain CW-2 and LS174T. RT-PCR and Northern blot were used to detect expression of iNOS mRNA in colon cancer. RESULTS: MTT growth curve displayed that colon cancer cell strain LS174T grew and reproduced faster than cell strain CW-2. RT-PCR showed that iNOS mRNA expressed strongly in CW-2 cell strain, while iNOS mRNA expressed weakly in LS174T cell strain. Northern blot detected that iNOS mRNA expressed obviously in CW-2 cell strain, but cell strain LS174T have no obvious iNOS mRNA expression. All-trans retinoic acid (ATRA) had no obvious effect on iNOS mRNA expression in CW-2 cell strain of colon cancer. CONCLUSIONS: ATRA has no obvious effect on iNOS mRNA expression. iNOS has a dual effect on tumor growth. In low-metastatic colon carcinoma CW-2, iNOS may exert a anti-tumor influence by cytotoxicity or inducing cell apoptosis. In high-metastatic colon cancer LS174T, iNOS produced low concentration of NO, which may be an important signal-transduction molecule for increasing blood supply and angiogenesis, which improve the growth, invasion and metastasis of tumor.

Objective To study the effect of Chinese herbs on human scalp hair growth in vitro. Methods Organ culture of human scalp hair follicles was used to study the effects of extracts of Crataegus cuneata, Ligustrum lucidum, Polyporus umbelatus and Bletilla striata mixture and ginseng saponin on hair growth. Results Low doses of mixture extracts(1.28 ?g/mL and 6.4 ?g/mL) markedly enhanced the hair growth and lengthened the period of hair growth, while high doses of mixture extracts(4 mg/mL and 20 mg/mL) sharply inhibited hair growth and shortened the period of hair growth. High doses of ginseng saponin (40 ?g/mL and 200 ?g/mL) also had an inhibiting effect on hair growth. Conclusion This observation suggests that extracts of Crataegus cuneata, Ligustrum lucidum, Polyporus umbelatus and Bletilla striata mixture can promote hair growth in vitro.
