[Objective] This paper investigates the impact of early intervention of gestational diabetes mel itus(GDM) on pregnancy outcomes. [Methods] Samples are drawn from the GDM cases diagnosed in Zhejiang Tonglu Maternity and Child Care Hospital between Jan. 2010 and Dec. 2012. The treat-ment group includes 56 cases that were diagnosed with systematic prenatal examination and received early treatment, while the remaining 42 cases in the control group were detected only in later phase of pregnancy and stayed untreated, upon which comparisons of pregnancy outcomes are made. [Results] Early intervention of GDM greatly improves the prognosis of both the mother and the perinatal stage infant, as demonstrated in statistical y significant dif-ference of complications. [Conclusion] Early intervention of gestational diabetes mel itus can reduce the chance of gestational complications, and further im-prove pregnancy outcomes.

Objective:To establish a method for the determination of organic residues ( hexane, benzene, toluene, xylene and sty-rene) in macroporous adsorption resins. Methods:Headspace-GC with a DB-624 column was used to determine the residues in macro-porous resins. The inlet temperature was 200℃ and the FID detector temperature was 240℃. The column temperature programming was as follows:the initial temperature was 40℃, maintained for 3 min, and then raised to 200℃ with the rate of 14℃/min and kept for 2 min. The solvent was methyl alcohol and the carrier gas was nitrogen. HPLC was applied to determine the contents of the five resi-dues. Results:The contents of the five organic residues were all below 20‰ in five macroporous resins in common use including D101, HPD100, AB-8, DM301 and NKA-9. Conclusion:The method is simple,accurate and reproducible. It can be used in the res-idue determination of macroporous resins.

Objectiv To evaluate the usefulness of dot immuno-gold filtration assay(DIGFA) for the diagnosis of Paragonimus infection.Methods During 2003 to 2006,72 cases suspected of paragonimiasis in Zhejiang Province were examined with DIGFA for rapid detection of specific antibodies against Paragonimus(Pw-DIGFA).The diagnosis was primarily established with the presence of antibodies,experience of ingesting raw freshwater crabs or crayfishes and clinical presentations.The cases were treated with praziquantel and followed-up at 3 and/or 6 months post-treatment.Antibody level in patients(pre-and post-treatment) were detected in parallel and analyzed comparatively by Pw-DIGFA and ELISA.Results The result of detection by Pw-DIGFA was in agreement with that of ELISA.28 of 72 cases were antibody positive and 44 cases were negative.Among the 28 positives,26 cases had a history of eating raw freshwater crab or crayfishes and the other 2 cases drank freshwater from brook before.21 cases showed paragonimiasis-related clinical symptoms such as low-grade fever,cough,or changes in image examination,while the other 7 cases showed only eosinophilia in peripheral blood(15%-70%).The mean absorbance values(A450) of positive sera,negative sera and normal sera tested by ELISA were 1.7361,0.2973 and 0.2657 respectively.There was significant difference between the positive cases and the negative cases(t=12.047,P0.05).At 3 month post-treatment,serum antibody in 5 cases whose clinical symptoms and physical signs relieved or disappeared decreased 2-5 titers and that of one case who relapsed with new signs increased by one titer.In Pw-DIGFA,the dot color of 5 cured cases showed a little weaker than that of pre-treatment and the relapsed case displayed similar response.At 6 month post-treatment,7 sera of clinically cured cases showed significantly weaker response than that of pre-treatment.The antibodies of those sera dropped 3-6 titers.Conclusion Pw-DIGFA is of supplementary value for clinical diagnosis of paragonimiasis.Antibody detection by pre-and post-treatment using Pw-DIGFA shows potential for the evaluation of therapeutic effect.

To determine the diagnostic value as well as the evaluation value in therapy, the specific IgM and IgG anti-bodies of the infected and treated rabbits were detected using soluble egg antigen(SEA) and adult worm antigen(AWA) by ELISA. By using SEA to detect the IgM antibodies, the serum antibody level rapidly dropped 7 weeks after infection even without treatment, and those of IgM in sera detected by AWA rose early than IgG detected by SEA. After 5 month treatment, IgM detected by AWA and IgG detected by SEA were still positive. From these observations, it is evident that SEA is a better antigen to detect specific IgG in the diagnosis of schistosomiasis, AWA is a better one for early diagnosis. The use of AWA as antigen to detect IgM showed high diagnostic value both in acute and chronic schistosomiasis. However, detection of the IgM/ IgG in ELISA using SEA and AWA could not evaluate the therapeutic effect well.

Objective To explore the related risk factors of severe mycoplasma pneumonia in children.Methods 86 children with mycoplasma pneumonia were selected as the observation group.At the same time,30 normal children were selected as the control group.The observation group included 33 cases of mild mycoplasma pneumo nia(A group) and 53 cases of severe mycoplasma pneumonia(B group).The clinical data of the three groups were ret rospectively analyzed,and the related risk factors of severe mycoplasma pneumonia in children were analyzed.Results The risk factors of severe mycoplasma pneumonia in children were age ＞ 5 years (x2 =28.776,P ＜ 0.05),immunoglobulin IgG(x2 =3.004,P ＜ 0.05),immunoglobulin IgM (x2 =2.147,P ＜ 0.05),immunoglobulin IgA (x2 =2.036,P ＜ 0.05),WBC (x2 =6.119,P ＜ 0.05),neutrophil percentage (x2 =8.374,P ＜ 0.05),the positive rate of CD8(x2 =11.665,P＜0.05),the positive rate of CD4(x2 =12.901,P＜0.05).Conclusion For children with risk factors of severe mycoplasma pneumonia should be early diagnosed,prevented and treated,thereby reducing the burden on patients.

Treatment of gynaeeological cancer frequently results in the loss of ovarian function and menopausal syndrome.The most effective treatment is hormone replacement therapy (HRT).According to the current studies,HRT does not increase the risk of recurrence or death in patients with early stage endometrial cancer and uterine leiomyosarcomas. The safety of HRT in ovarian cancer patients is inconclusive. Cervical squamous cell carcinoma, vaginal cancer and vulvar cancer are not contraindications for HRT. Estrogen replacement therapy (ERT) is contraindicated for low-grade endometrial stromal sarcomas. Therefore,after integrated risk assessment and discussion,patients with severe menopausal symptoms can be treated with HRT to improve the quality of life.

Objective To analyze the consistency of transcutaneous perianal ultrasonography (TPUS) and pelvic magnetic resonance imaging (MRI) in diagnosing perianal lesions of Crohn's disease (CD), and to evaluate the value of transcutaneous perianal ultrasonography in detecting perianal lesions of CD. Methods A cohort of 102 patients diagnosed as Corhn's disease were enrolled from August 2008 to August 2010. Perianal abscess and fistula of these CD patients was diagnosed by ultrasonography and MRI system. Statistics was performed with SPSS 11.5 software for X2 test. The consistency was analyzed with Kappa test. Results The mean onset time of perianal lesions in CD was -0.443 year (95％CI:-1.659～0.773 year) before typical symptoms showed up. There was no significant difference in detecting perianal lesions of CD between transcutaneous perianal ultrasonography and pelvic magnetic resonance imaging (P ＝ 0.706, Kappa ＝ 0.541). If pelvic magnetic resonance imaging was considered as the golden standard in detecting perianal lesions of CD,the sensitivity (Sen), specificity (Spe), Youden's index, positive predictive value (PPV) and negative predictive value (NPV) of TPUS were 72.73％, 82.61％, 0.55, 66.67％ and 86.36％ respectively.Furthermore, there was no significant difference between transcutaneous perianal ultrasonography and pelvic magnetic resonance imaging in detecting perianal abscess ( P ＝ 0.706, Kappa ＝ 0.496) and fistula (P＝0.655, Kappa＝0.546) of CD. Conclusions Perianal lesions occur in the entire course of CD. There was favorable consistency between transcutaneous perianal ultrasonography and pelvic magnetic resonance imaging in detecting perianal abscess and fistula of CD. Transcutaneous perianal ultrasonography can be used as an additional method in detecting and evaluting perianal lesions of CD.

Objective To investigate probable effect of metformin on anxiety and autophagy pathway in rats with focal cerebral ischemia . Methods The rats were divided into seven groups:shame group, ischemia group, metformin group, compound C group, compound C +ischemia group, metformin+ischemia group, and metformin+compound C+ischemia group.The rats were administered with metformin 14 days and compound C 30 min pretreatment.The blood glucose level, body mass, neurological score and indicators of elevate plus maze test were recorded of two groups after 72h ischemia-perfusion.The autophagy-related protein of Atg-7, Atg-5, beclin-1 were analysed by Western blot.ResuIts Metformin had no significant effect of body mass and blood glucose level.The prior administration of metformin significantly elevated neurological score in ischemia group (P<0.01).The elevate plus maze test results showed that prior administration of metformin significantly elevated percentage of open-arms detention time in ischemia group (P<0.01), but there was no significant difference in open-arms times.Western blot result showed that prior administration of metformin significantly elevated Atg-7, Atg-5, beclin-1 protein expression in ischemia group (P<0.001).Compound C resist the above effects of metformin (P<0.01).ConcIusion The metformin improves psychological disorders and movement disability through regulation of autophagy following focal cerebral ischemia in rats.
