Objective To discuss clinical features and harmfulness of acid-base imbalance in newborn by investigating the changes in blood gas of cord and artery blood,and to establish more appropriate prevention measures. Methods One hundred and ninety-two cord blood and 113 peripheral artery blood of neonates were measured for blood gas analysis by automatic blood gas analysis instrument from America;meanwhile,the concentrations of K~+,Na~+ and Cl~- were detected by biochemical analyzer.Results Among 192 neonates,179 were normal labor and 13 neonates underwent acidosis of different degrees.The incidence was 79.9%.Among the 13 ca-(ses),2 cases had severe asphyxia and both of them got serious mixed acidosis.For all the neonates, 156 cases got acidosis, 84 neonates underwent respiratory acidosis (43.8%), 47 cases with metabolic acidosis (24.5%) and 25 cases with mixed acidosis (13.0%).The left 113 neonates were abnormal labor.Among them,99 cases had acid-base disturbance of different degrees (87.6%). Among the 99 acid-base disturbance cases, 50 cases were single metabolic acidosis (44.2%) and presented the most common changes; the second was single respiratory acidosis, totally 20 cases (17.7%).The third was metabolic acidosis combined with respiratory alkalosis, totally 16 neonates (14.2%).Eleven cases had mixed acidosis (9.7%) and 2 cases were respiratory alkalosis combined with metabolic alkalosis (1.8%).Conclusions While the normal labor neonates still got acidosis of different degrees,the acid-base imbalance of abnormal labor is much more prominent,and the critical neonates often got mixed acid-base imbalance.Serious acid-base imbalance can cause fatal pathological changes in body.The dangers of acidosis and alkalosis can not ignore either. The condition of acid-base imbalance can be judged more accurately by the combination of blood gas analysis and anion gap.The perinatal health cares are important measures to prevent acid-base imbalance.

The origin and development of umbilical therapy in traditional Chinese medicine is explored from related literature in the history. As a result, the Shang period is regarded as initial period of umbilical therapy, while periods from Han Dynasty, Jin Dynasty and Southern-Northern Dynasties to Sui Dynasty and Tang Dynasty could be taken as stage of primary development. Time from Song Dynasty, Jin Dynasty and Yuan Dynasty to Ming and Qing Dynasties is believed as mature stage. Also the manipulation, application principle, indications and contraindications of umbilical therapy are explained. A brief overview of modern development of umbilical therapy is also described.

[Summary] According to the cutpoint of plasma triglycerides concentration ≥ 1.7 mmol/L,waist circumference ≥85 cm in men or ≥80 cm in women,459 patiens with type 2 diabetes mellitus were divided into four groups:normal waist circumference and triglycerides,normal waist circumference and hypertriglyceridemia,abdominal obesity and normal triglycerides,and hypertriglyceridemic-waist (HTWC) group.The results showed that body mass index,waist circumference,systolic blood pressure,triglycerides,microalbuminuria,and homeostasis model assessment insulin resistance index (HOMA-IR) in HTWC group were higher than those in non-HTWC groups (all P＜0.01),as well as higher diabetic nephropathy incidence (P＜0.05).Multiple logistic regression analysis revealed that HTWC was an independent risk factor of diabetic nephropathy (OR =2.070,95 ％ CI 1.195-3.586).

3T3-L1 adipocytes transfected with TSH receptor (TSHR) shRNA were incubated with bovine TSH.The concentration of tumor necrosis factor (TNF)-α in culture medium was measured by enzyme linked immunosorbent asssy.Protein level of insulin receptor substrate 1 (IRS-1) was quantified by Western blotting.Tyrosine phosphorylation of IRS-1 was measured by immunoprecipitation.The results showed that 1 mIU/ml TSH significantly sitmulated TNF-α release in 3T3-L1 adipocytes [(341.85 ± 12.00 vs 522.67 ± 36.22) ng/L,P＜0.01],along with the decreases in IRS-1 protein expression and its tyrosine phosphorylation (P＜ 0.01).These effects disappeared when TSHR expression was down-regulated with RNA interference in 3T3-L1 adipocytes.In addition,WP9QY,a TNF-α antagonist,blocked TSH-decreased IRS-1 expresssion.These results suggest that TSH downregulates IRS-1 protein expression and its tyrosine phosphorylation through stimulating production of TNF-α,and thus contributes to the development of insulin resistance.

Objective To study the changes of umbilical blood lactate,pH, blood sugar(BS),bilirubin, electrolyte, osmotic pressure (OP) in the newboms with fetal distress.Methods Thirty-five newborns with fetal distress (distress group) and 40 healthy new-borns (control group) were studied. Distress group were divided into distress group Ⅰ and distress group Ⅱ respectively, based on without or with neonatal asphyxia. Concentration of umbilical blood lactate was determined with enzyme method, pH, BS,serum total bilirubin (BIL), serum electrolyte (Na+ ,K+ ,Ca2+ ) and OP were analyzed respectively. Results 1. The difference of incidence of newborn asphyxia between distress groups (29.03%) and control group (2.50%) was statistically significant. 2. Compared with the controls and distress group Ⅰ, the umbilical blood lactate concentration significantly increased in distress group Ⅱ (P 0.05).The incidence of hyperglycemia was significantly elevated in distress groups than that in the control group. 4. Lactate concentration in distress I and distress fl group showed negative correlation with pH. Conclusion The concentration of umbilical blood lactate can provide the proof for diagnosis and prognosis of fetal distress.

Objective To explore the changes and clinical significance of prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT),fibrinogen time(FGB)and platelet(PLT)on Kawasaki disease(KD)in children with acute and convalescent 10 d,which aimed at early diagnosis,prediction and prognosis of coronary artery lesions.Methods Thirty-eight cases who were diagnosed KD were selected as KD group,30 cases age-matched acute respiratory infections in children with fever as fever group,moreover,30 cases of a class of elective surgery preoperative children admitted to surgical departments were put as control group.The plasma PT,APTT,TT,FGB,PLT of all cases and plasma APTT,FGB,PLT in recovery 10 d in children with KD disease were detected,and then the results were compared between the 3 groups;and the results of APTT,FGB,PLT in KD children with acute and convalescent 10 d to coronary artery dilatation groups or not were compared.Results 1.APTT prolonged and FGB,PLT increased in KD children with acute stage,which had a significant difference compared with other groups(Pa0.05).2.When comparing the results of APTT,FGB,PLT in KD children with acute and convalescent 10 d,the difference was significant(Pa
