Neonatal inherited metabolic diseases (IMD) screening has been widely conducted worldwide. Tandem mass spectrum (MS/MS) is the main procedure of IMD screening. As a new technique, gene sequencing has been put into practice for IMD screening. Nowadays, the morbidity and disease spectrum of IMD in China is still unclear. A summary of general and single morbidity, and disease spectrum of China's IMD from publications of MS/MS screening could provide evidence for establishing neonatal IMD's genetic test and formulation of laws and regulations.

Objective To evaluate endoscopic ultrasonography (EUS) in assessing endoscopic re-sectability of early esophagogastric cancer. Methods Data of 65 consecutive cases suspected as having early esophagogastric cancer with EUS and confirmed by pathology after endoscopic mucosal resection or endoscop-ic submucosal dissection within 2 weeks were retrospectively analyzed. The invasion depth of the lesion de-tected by EUS was compared with that from pathology. Results The accuracy of EUS in diagnosis of depth of early cancer invasion was 93.8% (61/65), and the overall accuracy in assessment of endoscopic resectabili-ty was 89. 2%. Conclusion Endoscopic resectability of early esophagogastric cancer can be accurately eval-uated with EUS.

Objective To analyze the etiology and clinical features of isolated gastric varices.Methods A retrospectives analysis was carried out in 31 patients with isolated gastric varices between January 2003 and January 2008.The patients records including data of etiology,clinical presentation,imaging studies and therapeutic modalities were reviewed.Results Those who had isolated gastric varices were accounted for 7.38 0A (31/420)of all patients with gastroesophageal varices.The etiologies were left-sided portal hypertension(14 cases,45.2%),liver cirrhosis(8 cases,25.8%),unknown origin(6 eases,19.4%),hepatocellular carcinoma(2 cases,6.5%),portal cavernous transformation(1 case,3.2%).Twenty-one patients(67.7%)had variceal hemorrhage.Splenomegaly was present in 21 cases(67.7%),among which 10 cases(32.3%)had concomitant hypersplenism.Venous involvement was identified in 18 patients(splenic vein obstruction in 9 cases and portal vein involvement in 9 cases).Surgical therapy was performed in 8 cases,selerotherapy in 3 cases,and medical therapy in 20 cases.Conclusions Left-side portal hypertension is responsible for most of the isolated gastric varices,and some of which are also caused by liver cirrhosis.Surgery is the appropriate procedure of choice in management of hemorrhage and recurrence.

Objective The purpose of this study was to evaluate the disinfection effectiveness and properties of acrylic resin via microwave irradiation. Methods Forty acrylic resin base dentures fabricated in a standardized procedure were chosen and divided into Group A,B,C and D randomly. Group A,B and C were immersed in 200ml distilled water and submitted to microwave irradiation at 700W for 3,4,5 minutes individually. Group D was used as positive control. Bacteria specimens from each group were got for culture and numbers were calculated. Then the four groups were tested for the flexural strength and impact strength by universal test machine before and after microwave irradiation sterilization. Results The germicidal ratio of Group B was more than 90% ,while the ratio of group C was 100%. There was no significant difference in flexural strength and impact strength between group C and group D. Conclusions Microwave irradiation for 5 minutes at 700W produced sterilization of dentures contaminated with all bacteria whereas the denture strength is not affected. Microwave irradiation at 700W solution for 5 minutes was effective to sterilize acrylic resin base dentures.

Objective To investigate the prevalence and clinical characteristics of thyroid dysfunction induced by IFNα therapy in patients with chronic hepatitis.Methods Thyroid function of 310 patients with chronic hepatitis receiving IFNα therapy were evaluated.Results Serum free tri-iodothymnine (F13),free thyroxine(FT4)and sensitive thyroid-stimulating hormone(sTSH)of all patients were normal and TGAb was negative before IFNα therapy.After the treatment,10 patients(10/3 10,3.22%)had thyroid dysfunction,in which 7 were of hypothyroidism and 3 were of hyperthyroidism.The thyroid function of all patients recovered within 1-year follow-up.Conclusions IFNα therapy may induce thyroid dysfunction in patients with chronic hepatitis,in which prognosis can be good when appropriate treatment is given.

Objective To study the psychological nursing on the rehabilitation effect of patients with acute coronary syndrome(ACS)accompanied by depression.Methods 126 ACS patients were divided into the nursing group(64 cases)and the control group(62 cases)randomly.The control group adopted roUtine rehabilitative nursing measurs.While the nursing group received canonical and selective psychological nursing.The Zung Self-rating Depression Scale(SDS)and hamilton depression scale(HAMD)were used to evaluate the their psychological status.The electrocardiogram,clinical symptom and cardiovascular complications were observed and compared.Results The SDS and HAMD scores were different between the nursing group and the control group(P＜0.01)5 weeks after rehabilitative nursing but not before it.The ischemic changes of electrocardiogram,incidence frequency of angina pectoris and cardiovascular complications were significantly decreased in the nursing group compared with the control group(P＜0.05).Conclusion Psychological nursing could not only alleviate the depression of patients with ACS but also could improve the clinical symptoms of these patients and decrease the incidence frequency of cardiovascular events.

ThemagneticFe3O4nanoparticlesweresynthesizedbyco-precipitationmethod,andthenmagnetic Fe3 O4@Au nanoparticle was synthesized to improve the affinity of particle surface. L-Cys-GA3 was grafted on the surface of gold clad by self-assembly method, and then dropped it on glassy carbon electrode, for further manufacture of MIP/Fe3 O4@Au by using electropolymerzation L-Cys. The surface morphology and particle size distribution of Fe3 O4@Au were studied by TEM. The structure and composition of gibberellins A3, MIP and nMIP were studied by IR. The test system was optimized, and the results showed that when the cycles of electropolymerization was 30, acetic acid:methanol (1:8, V/V) was chosen as eluent, elution time was optimized for 5 min and rebinding time for 7 min, the sensor got a high stability and good recognition ability for gibberellins A3 . The concentration of gibberellins A3 in the range of 1 . 0 × 10-11-1 . 0 × 10-8 mol/L had a relationship with the oxidation peak current of probe, with the detection limit of 2. 57×10-12 mol/L. The sensor was successfully used for the determination of GA3 in beer sample.

Objective To compare the efficacy of stents 7 F and 10 F in drainage of pancreatic pseudocyst via EUS-FNA.Methods A retrospective analysis of patients with pancreatic pseudocyst who received endoscopic ultrasonography guided puncture drainage by using 7 F and 10 F double pigtail plastic stent respectively in Drum Tower Hospital of Nanjing University Medical School from 2010 to 2014 was conducted.Patients' hospitalization period, the time for 50％ cyst reduction, removal time, infection rate, and recurrence rate were compared.Results Twenty three patients with pancreatic pseudocyst were included, among whom 14 were male and 9 were female.The age ranged from 13 to 70 with an average of 45.1 years.Eleven patients were treated with 7 F pigtail plastic stents whereas 12 patients with 10 F pigtail plastic stents.All patients were treated with additional 8.5 F joint nose cyst drainage.Four cases in 7 F group got fever, 3 of whom were successful in anti-infection and 1 failed, having to change the stent.One case (9.1％) relapsed without symptoms after 52 months during the follow-up and received no intervention.Five cases in 10 F group got fever, 4 of whom were successful in anti-infection and 1 failed, having to change the stent.One case (8.3％) was identified as mild hemorrhage, and replantation needed to be performed in 1 case (8.3％) because stent was found to slip after 12 days.Two cases (16.7％) relapsed without symptoms after 11 and 24 months respectively and no intervention was received.There was no significant difference in patients' age, cyst size, removal time, infection rate and recurrence rate between the two groups.However, patients in group 10 F had a markedly shorter hospitalization period and time for cyst reduction by at least 50％ than those in group 7 F (P ＜ 0.05).Conclusion 10 F double pigtail plastic stents can drain the cyst faster, shorten the hospital stay, but there is no significant difference in infection or recurrence rate of cyst compared with 7 F stents.

Objective To analyze the relationship between the levels of plasma total homocysteine (Hcy) and umbilical arterial with color doppler ultrasound with the severity of preeclampsia(PE).Methods A total of 70 cases of the third trimester of normal pregnancy, 72 cases of mild PE, and 66 cases of severe PE were selected.Then plasma Hcy levels and umbilical arterial with color doppler ultrasound were detected.Results Hcy levels were statistically significant difference among the normal control group,mild PE group,and severe PE group((8.950±0.585), (11.116±0.615), (14.648±0.620) μmol/L,P＜0.05).Umbilical artery blood flow parameter S/D values in severe PE group was significantly higher in mild PE group and in contrg.1 group (3.43 ±0.72 vs.2.86 ± 0.82 vs 2.75 ± 0.56, P＜ 0.05), while the control group, mild PE group had no significant difference(P＞0.05).Resistance index(RI) ,Pulsatility index(PI) in mild PE group and severe PE group were significantly higher than control group(0.60±0.05,0.78±0.07 vs.0.57±0.06;1.24±0.21,1.47±0.64 vs.0.67±0.35), and the differences among three groups were significant(P＜0.05), while the mild PE, severe PE group had no significant difference(P＞0.05).Hcy of mild PE group was positively correlated with S/D, RI and PI(r=0.548,P=0.009;r=0.587,P=0.008;r=0.324,P=0.02).Hcy of severe PE group was positively correlated with S/D,RI and PI(r=0.752,P=0.001;r=0.627,P=0.003;r =0.438,P=0.024).Hcy and the severity of PE was positively correlated (r =0.450, P ＜ 0.05), S/D and the severity of PE was positively correlated(r=0.316, P =0.002).RI, PI and the severity of PE was no correlation (r =0.024, P =0.726;r =0.054,P =0.649).Conclusion The levels of Hcy and S/D were related to the severity of PE.To reduce Hcy,and monitor S/D were new ways for the diagnosis and treatment of pre-eclampsia.

Objective To analyze the clinical features of patients with IgG4-associated biliary and pancreatic diseases,and to improve the understanding of these diseases.Methods Nine cases of patients with IgG4-associated pancreatitis and cholangitis were analyzed retrospectively,which included clinical manifestations,serological examination,imaging test,pathology,treatment and prognosis.Results Of the 9 patients,8 were male,1 was female,the average age was 61 years old.Four cases were presented with jaundice,2 cases with jaundice and abdominal pain,2 cases with abdominal pain,and 1 case with diabetes.Serum IgG4 levels were 3.46-21.3 g/L (mean 9.743 g/L) in 6 cases,and which were higher than normal value,3 patients did not undergo blood test of IgG4.Nineteen auto-antibodies (including ANCA) were all negative in 9 cases.CA19-9 was increased in 4 cases.CT manifestations showed 5 cases with low density pancreas mass (2 cases with biliary tract dilatation);1 case had pancreas swelling with dilatation of bile duct,and 2 cases with bile duct dilatation only,and CT findings in 1 case were negative.Four patients underwent EUS-FNA,and EUS features included hypoechoic lesions without peripancreatic lymph nodes.FNA results indicated 2 cases with IgG4 related chronic inflammation,2 cases with chronic inflammation with negative IgG4.Seven cases were confirmed to have IgG4 related pancreatitis,and 2 cases with IgG4 related cholangitis.Six patients received glucocorticoid treatment,and the dose ranged from 8-40 mg;3 patients underwent surgery and the surgical pathology indicated IgG4 positive plasma cell.Follow-up showed the serum IgG4 returned to normal,clinical symptoms improved remarkably,and pancreatic mass decreased.Conclusions IgG4 positive plasma cell infiltration is the main feature of IgG4-associated cholangitis and pancreatitis.The diagnosis should combine image,serology with pathology.Glucocorticoid is an effective treatment.
