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.

To establish a murine carotid artery transplantation model for the study of the chronic rejection, 80 rats were divided into two groups, an allotransplant (ACI-Lewis) group and an isotransplant (Lewis-Lewis) group (control group). The donor carotid artery and the recipient carotid artery were anastomosed by using a polyethylene cuff (internal diameter: 0.7 mm, length: 3 mm).The pathological changes of carotid artery transplant were observed 14, 28 and 56 days after the transplantation. The results showed that the model was successfully established in 95% of the animals. The chronic rejection-associated arteriosclerosis was induced 28 days after the transplantation. The new chronic rejection model of carotid artery by using cuff technique caused fewer traumas and was easy to make. The pathological changes of the transplant mimicked the chronic rejection-associated arteriosclerosis found in human transplant.

Conclusions -2578 single nucleotide polymorphism in the VEGF gene promoter is associated w ith carotid atherosclerosis, and C al ele may be its genetic susceptibility factor in Chinese Han population in Shandong, China.

Objective To investigate the protective effect of RLN revealed for RLN in high -risk thyroid surgery,and the clinical value of detecting nerve,thus to provide a reference for clinical treatment.Methods 132 patients of thyroid high -risk surgery were selected,according to whether to explode recurrent laryngeal nerve,they were divided into exposed group (80 cases)and non -exploded group(52 cases).The recurrent laryngeal nerve damage rate,clinical indicators of operation time were compared between the two groups.In the explode group,80 patients according to whether implementation of the nerve monitoring,were divided into the monitored group (36 cases)and non -monitored group(44 cases).The hours to find the nerve,recurrent laryngeal nerve injury rates and other indicators were compared.Results The operative time of the exploded group was (133.66 ±21.48)min,which was significantly longer than the non -exploded group,difference was statistically significant (t =3.994,P =0.025 ).The exposed group had similar incidence of hypocalcemia compared with the other groups,there was no statistically significant difference (P >0.05).The revealing recurrent laryngeal nerve injury rate of the exposed group was 2.50%,which was significantly lower than the non -exploded group,difference was statistically significant (χ2 =5.794,P =0.008).The recurrent laryngeal nerve positioning time of the monitoring group was (4.78 ±0.94)min,which was significantly shorter than the unmonitored group,difference was statistically significant (t =7.168,P =0.001).The recurrent laryngeal nerve injury rate of the monitoring group was 2.78%,showed no significant difference (χ2 =0.911,P =0.338).Conclusion In a high risk thyroid surgery,explode recurrent laryngeal nerve can reduce the rate of recurrent laryngeal nerve damage,nerve monitoring can effectively speed up the nerve localization time,but has no significant effect on reduce the rate of recurrent laryngeal nerve injury.

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.
