Objective To explore the correlation between simple thyroid peroxidase antibody (TPOAb) positive (higher than the normal reference value) and the adverse pregnancy outcomes;and to discuss the necessity of clinical intervention on TPOAb positive and the characteristic of gestational thyroid peroxidase antibody changes.To study wether clinical intervention affects its direction.Methods Subjects were selected from TPOAb positive pregnant women during June 2012 to February 2015.They were registered regularly for thyroid function during pregnancy and 6 weeks postpartum,and timely treated for abnormal thyroid function.They were grouped according to the thyroid function:Group 1 (n =122),simple TPOAb positive group;Group 2 (n =67),patients with elevated TSH and positive TPOAb who accept the levothyroxine (L-T4) intervention;Group 3 (n =120),TPOAb negative healthy pregnant women.They were regularly tested for thyroid function during pregnancy,and with follow-up until 6 weeks postpartum.Results When Group 1 compared with Group 3:the risk of premature rupture of membranes,abnormal amniotic fluid,and fetal distress rate increased,the relative risk (RR) were 3.066,4.782,2.605,all P ＜0.01,while the gestational diabetes,gestational hypertension,preterm birth,abnormal gestation and birth showed no statistical differences (P＞0.05).When Group 2 compared with Group 3,the risk of premature rupture of membranes,abnormal amniotic fluid,and fetal distress increased (RR were 3.830,5.537,3.600 respectively,all P ＜ 0.01).While gestational diabetes,gestational hypertension,preterm birth,abnormal gestation and birth did not show any statistical difference (P＞0.05).Compared with Group 2,Group 1 had no statistical difference between the above observational parameters.The levels of TPOAb from stage T1 (the first trimester) to T3(the third trimester) showed a overall downward trend in Group 1 and Group 2,rise again six weeks after child birth.Comparison of the two groups (Group 1 and Group 2),the median value during this period did not reveal any significantly statistical differences (P＞ 0.05).Conclusion In simple TPOAb positive pregnant women,premature rupture of membranes,abnormality in amniotic fluid,and fetal distress were significantly higher than those in healthy pregnant women;even with thyroid function correction the TPOAb positive pregnant women still cannot reduce the adverse pregnancy outcomes.Levels of TPOAb from T1 to T3 presented the overall downward trend and to rise again six weeks after pregnancy.L-T4 intervention for TPOAb positive pregnancy did not show any significant effect.

Klebsiella pneumoniae is one of the most important gram-negative bacteria clinically. Klebsiella infections are seen mostly in people with a weakened immune system.Klebsiella can cause infec-tions in the respiratory tract,urinary tract,lower biliary tract,and surgical wound sites.The range of clinical diseases includes pneumonia,thrombophlebitis,urinary tract infection,pyogenic liver abscess,cholecystitis,di-arrhea,upper respiratory tract infection,wound infection,osteomyelitis,meningitis,and bacteremia and septi-cemia.The most common condition caused by Klebsiella bacteria is pneumonia,and the worst condition is septic shock.Klebsiella organisms are often resistant to multiple antibiotics.Klebsiella with the ability to pro-duce extended-spectrum beta-lactamases is resistant to many classes of antibiotics.Therefore,prevent sprea-ding Klebsiella infections and give effective treatment to patients are most important task for us.

Objective:To select an appropriate dosage of IL-2 for tumor infiltrating lymphocyte(TIL).Methods:Isolated by the attachment method we established,TIL was cultivated in self-supernatant of malignant pleura,with three different concentrations of IL-2,such as 6000u per ml,6000u per ml for the first administration followed by 1000u per ml,or 1000u per ml.The expansion,killing activity and phenotype changes of TIL cultured in different cultures were assessed.Results:As cultured in self-supernatant of malignant pleura fluid,the concentrations of IL-2,such as 6000u per ml or 6000u per ml for the first administration followed by 1000u per ml seemed benefit for TIL proliferation.Conclusion:6000u per ml of IL-2 for the first administration was very important.It could help TIL to activate and proliferate early.The study described here offers the possibility for TIL cultured in vitro self-supernatant of malignant pleura fluid in vitro for a short time,and then reinfuse to thorax for further expanding and controlling the malignant pleura effusion in the presence of IL-2,and thereby minimizing the risks of contamination.

Objective:To study the effect of autologous supernatant of malignant pleura effusion and RPMI1640 with 10% AB+ serum on the culture of tumor infiltrating lymphocytes (TIL) in vitro. Methods:Isolated by the attachment method we established, TIL was cultured in either autologous supernatant of malignant pleura fluid or RPMI1640 with 10% AB+ serum, and various types of cytokines such as (IL-2,) PHA and antibody against CD3 (OKT3) were added into both cultures. The proliferation as well as the killing activity and the phenotype changes of TIL cultured in the two kinds of cultures were compared. Results:There was no difference in the proliferation or the killing activity in vitro as well as the phenotype changes of TIL between the two kinds of cultures. Conclusion: Autologous supernatant of malignant pleura fluid could be used as TIL culture medium. The method described here made it possible for TIL to be cultured in vitro for a short time, and then reinfused back to thorax for further expanding and controlling the malignant pleura effusion in the presence of IL-2, and it alsominimized the risks of contamination.

Objective To investigate the clinical and laboratory characters of infantile organic acidemia(OA) accompanied with acute metabolic crisis.Methods We analyzed retrospectively datum of infants with OA diagnosed in our unit from April 2006 to October 2014.Results Fity-three cases(37 male and 16 female,aged under 1 year old) were enrolled in this study,in which,28 cases were methylmalonic acidemia,11 cases were propionic acidemia,3 cases were biotinidase deficiency,3 cases were glutaric acidemia type Ⅱ,2 cases were glutaric acidemia type Ⅰ,2 cases were isovaleric acidemia,1 case was variety of coenzyme A carboxylase deficiency,1 case was glycerol kinase deficiency,1 case was 3-methylcrotonyl-CoA carboxylase deficiency and 1 case was holocarboxylase synthetase defect.Tweny-five of the 53 cases(47.2％)developed metabolic crisis within 7 days after onset,main manifestations included feeding difficulties,frequent seizures dyspnea,et al.The most common abnormal laboratory findings manifested severe hypoglycemia,intractable metabolic acidosis,hyperammonemia,et al.Twenty cases had family history.All patients were given symptomatic relief and supportive treatment,including colleting hypoglycemia,reducing hyperammonemia,keeping water,electrolyte and acid base balance,maintaining function of vital organs,suppling metabolic cofactor and special fomula,et al.After treatment,32 cases (60.4％) improved markedly while death occurred in 15 cases(28.3％).Conclusion OA confirmed under 1 year old is especially vulnerable to acute metabolic crisis,which characterized by sudden onset,rapid progress and is difficult to treat.Feeding difficulties,frequent seizures and dyspnea were the very common presentations.Early diagnosis and timely treatment are critical for improving the prognosis.Clinicians should be aware of it,and an early metabolic disorders screening should be intervened in patients with hypoglycemia of unknown etiology or refractory metabolic acidosis.

Objective:The aim of this study was to investigate the association of mRNA expressions of ERCC1 (excision repair cross-complementing group 1) and BRCA1 (breast cancer 1) with chemosensitivity to cisplatin in malignant pleural and peritoneal effusions.Methods:Malignant pleural and peritoneal effusions were collected from 46 patients diagnosed with stage Ⅳ malignant tumor, prospectively. The tumor cells were isolated and the sensitivity of tumor cells to cisplatin was detected by adenosine triphosphate-bioluminescence assay (ATP-TCA). Real-time quantitative PCR was used to determine the mRNA expressions of ERCC1 and BRCA1. Results:The expression level of ERCC1 mRNA was negatively correlated with sensitivity of non-small cell lung cancer (NSCLC) to cisplatin (P= 0.001, r=0.685). BRCA1 mRNA expression level had negative correlation with sensitivity to cisplatin in both NSCLC (P=0.014, r=0.541) and gastric cancer (P=0.002, r=0.625). A significant interaction was found between the effects of ERCC1 and BRCA1 mRNA expressions on sensitivity to cisplatin (P=0.010 for all patients;P=0.027 for gastric cancer patients).Conclusion:ERCC1 and BRCA1 mRNA expression levels correlated with ex vivo chemosensitivity of tumor cells to cisplatin in malignant pleural and peritoneal effusions. Detection of both ERCC1 and BRCA1 may have a higher reliability in predicting the sensitivity of tumor cells to cisplatin than detection of single ERCC1 or BRCA1 expression.

Because of the extreme similarity in external form between some poisonous mushroom and wild large edible fungi,mushroom poisoning often occurs because of eating the poisonous mushroom by mistake every year in home and abroad.The known poisonous mushroom toxins include cyclopeptide toxin, muscarine,isooxazole derivatives and so on. According to the onset time, it is divided into early-onset, late-onset, and slow-onset style poisoning. According to the different clinical manifestations and the main organ damage, the types of toadstool poisoning were divided into gastrointestinal type, neuropsychiatric type,hemolytic toxin type and multiple organ damage type.The main treatment includes removing the toxic substances,supporting treatment of the disease,and applying the effective antidote,adrenal corticosteroids and blood purification.Avoiding eating poisonous mushrooms is an effective preventive measure.
