Objective To explore the incidence and distribution features of neonatal phenylketonuria(PKU) and congenital hypothyroidism(CH) in Lianyungang area.Methods The heel blood samples dried on filter paper was collected from newborns after 72 hours.As the screening indicators,PKU was detected through serum phenylalanine concentration(Phe) detection by Guthrie′s bacterial inhibition assay and CH was detected through serum thyroid stimulating hormone(TSH) levels detection by time-resolved fluorometry(TRFIA) or enzyme linked immunosorbent assay(ELISA).Results Sixty-four children with CH were diagnosed and the rate of CH was 1∶2423,41 patients were examined by thyroid gland nuclein kinescope picture,among which there were 23 patients whose thyroid glands were unusal.These patients lived in 45 towns(streets),which had no difference between men and women,city and country side.A couple of twins were screened for CH;15 cases of PKU was detected with an incidence of 1∶10 339.These patients′ parents were neither consanguineous marriage nor dominance hereditary family history.Their physical and mental development were similar to the same age children after interventive treatment.Conclusions The distribution of CH and PKU is diffuse in Lianyungang.Neonatal screening is the only valid means to find patients with CH and PKU.

Berberine, an isoquinoline alkaloid isolated from some Chinese medicinal herbs such as Coptidis rhizoma, has been used for the treatment of diarrhea and other gastrointestinal infections as an antibacterial drug in Chinese medicine. In recent years, it was reported to have beneficial effects on the metabolism disorders states of diabetes. The mechanisms involve many aspects of the diabetes, including regulating the blood cholesterol and triglyceride, lowering blood glucose, ameliorating the insulin resistant state and influencing the function of the pancreatic beta cell.

Objective To estimate the application value of dual-source CT on preoperational evaluating new type of three branches aortic arch covered stent graft implantation on DeBakey type I aortic dissection.Methods 20 cases with DeBakey type I aortic dissec-tion prepared to performe three branches aortic arch covered stent graft implantation were reviewed,and their CT findings were ana-lyzed in order to evaluate the guiding value for operation.Results The location and size of entries were determined and the diameter of aortic arch and three branchesas well as the intervals of three branches were also measured by dual-source CT.Furthermore, blood-supply for main vessel and complications related with covered stent were further analyzed prior to operation.The surgical pro-tocols were designed according to preoperational CT findings.Among all cases,13 cases were fit for new type of three branches aor-tic arch covered stent graft implantation.While the rest cases (N=7)were adopted other operations due to non-fitted indications. Conclusion Dual-source CT is of significance for preoperational evaluating new type of three branches aortic arch covered stent graft implantation on DeBakey type I aortic dissection.

Objective To study imaging features of primary chondrosarcomas and the correlation with pathologic basis.Methods The imaging materials of primary chondrosarcoma in 21 cases were retrospectively analyzed and correlated with pathological results. Results In 21 cases,the pathologic classifications were as following:15 cases of conventional intramedullary,1 case mesenchymal,2 cases myxoid,1 case dedifferentiated and 2 cases with no subtypes.For 6 cases of conventional intramedullary in gradeⅠand 8 cases in gradeⅡ,bone destruction in varying degrees accompanied with soft tissue mass(n=1 1),regional thickening cortical bone (n=2),“ring-arc”like matrix mineralization(n=6),amorphous (n=3)were showed on X-ray study.CT were performed,in 6 cases in gradeⅠ,6 cases in gradeⅡ and 1 case in grade Ⅲ in which there were intraosseous calcification (n=12),regional thickening cortical bone (n=2)and periosteal new bone formation (n=1).Lesions appeared expansive or osteolytic bone destruction accompanied with soft tissue mass on CT and MRI srudy MRI were performed in 5 cases in gradeⅠ and lesions were heterogeneous high signal intensity on T2 WI with spot like and “ring-arc”like low signal intensity.Conclusion Pathologic classifications and grading of primary chondrosarcoma may be presumed with imaging features.Pathologic characteristic manifestions on MR are superior to that on CT and X-ray.

Objective To study the effect of cardiac troponin T(cTnT)on the prognosis of chronic heart failure in the elderly patients.Methods Serum level of cTnT,and serum activities of creatine kinase (CK)and creatine kinase-MB(CK-MB)were measured in 60 elderly patients of chronic heart failure with varied classes of cardiac function.Cardiac events,including malignant cardiac arrhythemia,repeated or aggravated heart failure or cardiac death,in patients with increased cTnT during hospitalization were compared to those without it.Results Serum level averaged(89.1?13.6)mmol/L for CK and(7.9? 1.4)mmol/L for CK-MB in 20 patients with Class Ⅱ cardiac function by New York Heart Association (NYHA)classification and without increased cTnT,(88.2?13.4)mmol/L for CK and(7.5?1.8) mmol/L for CK-MB in 19 patients with Class Ⅲ cardiac function and four of them with increased cTnT,and (93.3?14.2)mmol/L for CK and(8.1?1.6)mmol/L for CK-MB in 21 patients with Class Ⅳ cardiac function and 14 of them with increased cTnT.Malignant cardiac arrhythemia occurred in six,repeated heart failure in eight,and death in three of 18 patients with increased cTnT,and one,two and one in 22 patients without increased cTnT,respectively.Incidence of cardiac events was higher in patients with increased cTnT than those without it(P

OBJECTIVETo explore the effect of Buzhong Yiqi decoction on PI3K/AKT signaling pathway in spleen, stomach and lung of nude mice with lung adenocarcinoma transplantation tumor.
METHODTotally 60 nude mice were randomly divided into the blank control group, the tumor-bearing control group, the cisplatin group, the low-dose Buzhong Yiqi decoction group, the middle-dose Buzhong Yiqi decoction group and the high-dose Buzhong Yiqi decoction group. After the corresponding interventions, efforts were made to measure the transplanted tumor volume and calculate the tumor inhibiting rate. The immunohistochemical method and real time PCR were used to detect the expression of PI3K and AKT level in nude mice spleen, stomach and lung.
RESULTBuzhong Yiqi decoction of different concentrations combined with cisplatin could inhibit the growth of the transplanted tumor, with the strongest inhibitory effect in the middle-dose Buzhong Yiqi decoction group and the high-dose Buzhong Yiqi decoction group. All of the expressions of PI3K and AKT protein and gene in the spleen, stomach and lung increased, with the most significant increase in the tumor-bearing group. Along with the increase of the concentration of cisplatin and Buzhong Yiqi decoction, the expressions of PI3K and AKT gradually reduced. Compared with the tumor-bearing control group, there were statistical differences in spleen and stomach tissues (P < 0.05). Compared with the cisplatin group, the middle-dose Buzhong Yiqi decoction group and the high-dose Buzhong Yiqi decoction group showed statistical differences (P < 0.05), but without statistical difference compared with the blank control group.
CONCLUSIONAmong nude mice with lung adenocarcinoma transplantation tumor, the PI3K and AKT protein and gene expressions in spleen, stomach and lung tissues increased, which might indicated the effect of cisplatin and Buzhong Yiqi decoction in reducing PI3K and AKT expressions and the relations between the reduction degree and the concentrations of Buzhong Yiqi decoction. Cisplatin combined with Buzhong Yiqi decoction could decrease the PI3K and AKT protein and gene expression in spleen, stomach and lung, and make the pathway closer to normal, so as to protect the functions of spleen, stomach and lung, there may be target spots of Buzhong Yiqi decoction in PI3K/AKT signal pathway.
