Objective To explore the clinical feature,treatment and prognosis of neonatal small intestinal atresia.Methods Retrospective study was carried out of 80 neonatal small intestinal atresias over the last 14 years,including diagnosis,treatment and prognosis.Results Of them,62 cases were healed(77.5%),18 cases were dead(22.5%),24 cases(30%)associated with other anomalities.The living cases were followed up for 6 months to 3 years.These symptoms had not relapse.Conclusions Satisfactry effect can be obtained by early diagnosis and operative treatment.Sonography is an ideal way for early finding intestinal atresias in a fetus.End-to-end single layer anastomosis is an ideal way for monointestinal atresia,and poly-end-to-end single layer anastomosis plus long gastrointestinal silicone tube for supporting is an ideal way for multipal intestinal atresia.

Objective Valsartan, the angiotensin Ⅱ type 1 receptor blocker, is recently proved to reduce urinary albumin at the microalbuminuria stage in human diabetic nephropathy without altering glucose metabolism. But the pathway is still uncertain. In present study, we examined the changes of adrenomedullin receptor (ADMR) mRNA and protein expressions in the renal cortex of diabetic rats to investigate the protective effects of valsartan on an experimental model of diabetic renal injury. Method The SD rats were randomly divided into following groups: normal rats, STZ-induced diabetic rats, and diabetic rats treated with valsartan. STZ-induced diabetic rats were treated with valsartan (10mg/kg body weight) or vehicle for 8 weeks. The expressions of ADMR mRNA in renal cortex were analyzed by RT-PCR, as well as ADMR protein expressions were detected through western blot. Results We found (1) Valsartan treatments reduced urinary albumin excretion in 24h, compared with the untreated. But no notable difference was seen in HbA1c and blood sugar of diabetic rats between the two groups. (2) Valsartan treatments increased the expressions of ADMR mRNA and protein in diabetic rats renal cortex. Conclusion These results indicate that valsartan treatment can upgrade the expressions of ADMR in the renal cortex of diabetic rats. It may be one of renal protective pathways of Ang Ⅱ type 1 receptor blocker.

The B.subtilis ywtD gene,encoding a ?-polyglutamic acid(?-PGA)depolymerase,was amplified from the genome of B.subtilis NX-2 by PCR.The comparability between the cloned ywtD gene sequence to the reported sequence is high to 99.0%.Only one of the substituted nucleotide base caused the change to the amino acid sequence.The recombinant plasmid pET-15b-ywtD was then transformed into E.coli Rosetta(DE3)and the ywtD gene product could be expressed with the induction of 0.5mmol/L IPTG.The YwtD protein exhibited a remarkable activity in ?-polyglutamic acid degradation.The molecular weight of ?-PGA could be reduced from 700kDa to 20kDa after 72h through the enzymatic hydrolysis and consequently trended to be constant.

Aim To observe whether DHEA has enhancing effect on DbcAMP -induced differentiation of NG108-15 cells, including neurite outgrowth, and study its possible mechanisms. Methods NG108-15 cells (a h ybrid cell line of mouse neuroblastoma and rat glioma) were used as a substitute for primary culture neuron in vitro. The morphology of NG108-15 cells was o bserved and neurite outgrowth was determined in an inversed microscope after treatme nt with various drugs. Gelatin-substrate gel electrophoresis was used to detect gelatinases (MMP-9 and MMP-2). Results ① DHEA and DbcAMP inhibited NG108-15 proliferation.②DHEA had enhancing effect on the promoting activity of neuronal differentiation and neurite outgrowth by DbcAMP. DbcAMP could increase neurite elongation of NG108-15 cells. Compared with this, the combined treatment with DHEA and DbcAMP significantly enhanced the neurite outgrowth of NG108-15 cells, including neurite length and numbers of cells with neurite, in a DHEA dose-dependent manner. ③ MMPs were involved in neuronal differentiation. DbcAMP induced the increase in MMP-9 and MMP-2 activities and such elevation was enhanced by DHEA in a dose-dependent manner. Conclusion DHEA enhances the effect of DbcAMP in promoting the neurite outgrowth of NG108-15 cells, which might be related to the increase in MMP-9 and MMP-2 activities.

Objective To study the pathological features of two huge spontaneous tumors in Wistar and GK rats. Methods Forty Wistar rats and 40 GK rats were included in this study. Among those rats, two huge spontaneous tumors were observed in a Wistar rat at 14 months of age and in a GK rat at 22 months of age. The growth and survival status of the tumor?bearing rats were recorded. The tumors were surgically removed, and their pathological features were examined using HE and immunohistochemical staining (vimentin, CK19, α?SMA, CD31, CD34, S?100, NF及Ki?67). Results Both the two tumors were completely resected by surgery without much difficulties, and both host rats survived well after the operation. The weight of the two huge tumors was 502 g and 119 g, which corresponding to 64% and 24% of the body weight of their host rats, respectively. The tumors surface had a complete capsule, with a clear boundary separating from the normal surrounding tissues, and no vascular pedicle structure was found. According to the results of immunohistochemical staining, both the two tumors were diagnosed as benign fibroma. Conclusion This type of huge spontaneous tumors is benign fibroma. Besides the impact on the activities of the rats, the tumors have no significant impact on the living conditions in the hosts.

BACKGROUND:Resin infiltration is a novel approach in treating non-cavitated caries lesions on smooth surfaces, and the effectiveness comparison between resin infiltration and remineralizing therapy is required.
OBJECTIVE:To compare the effects of resin infiltration and remineralizing therapy on inhibition of non-cavitated lesions in vitro.
METHODS:Three subsurface lesions were created on 35 bovine labial specimens. One of the lesions was permeated with Icon? infiltrant, one was applied by 0.1%NaF solution daily for 7 consecutive days, whereas one lesion remained as the untreated control. Subsequently, half of each specimen was covered with nail varnish
(baseline) and the other half was re-exposed to a demineralizing solution for 5 days (experimental). The specimens were cut perpendicularly to the surface, stained with Rhodamine B and observed with fluorescence microscope.
RESULTS AND CONCLUSION:For lesions permeated with Icon? infiltrant and applied by 0.1%NaF solution, the progression of lesion depth was significantly decreased (P<0.05) compared with the untreated control. Lesions permeated with Icon? infiltrant got more significantly reduced lesion progression (P<0.05) compared with the ones applied by 0.1%NaF solution. It can be concluded that both resin infiltration and remineralizing therapy have active effects on inhibition of non-cavitated lesions, and fil ing the pores with Icon? infiltrant can inhibit further demineralization even better.
