Objective To determine the change of maternal heart rate during the treatment with ritodrine for threatened premature labor. Methods110 cases of threatened premature labor were chosen. The ritodrine 100mg in 5% G. S 500mL was intravenously administered. The initial dosage was 6 drops/min, and the dose was increased until uterine contractions were inhibited. The treatment lasted for 40 to 48 hours after the uterine contractions were inhibited, then the oral tablets was recommended. If necessary, repeated treatment was given to some patients. The maternal heart rate was recorded in the whole process of treatment and was compared with the dosage administered. The labor time, fetal weight and Apgar′s score were also analyzed. Results The maternal basic heart rate was increased at first and then decreased. The increasing significantly increased( P ＜ 0.01 ) when the uterine contraction was inhibited. , but no difference showed among the groups of different gestational age( P＞0.05 ). The maternal heart rate was increased with the increasing of ritodrine( max. 140/min). labor time was significantly prolonged with the treatment of ritodrine( P＜0.01 ) ,while that of the idiopathic premature labor was prolonged most obviously ( P ＜ 0.05 ). Average fetal weight was (2.42 ± 0.49) kg, and the average Apgar′s score was≥8. Conclusion In the treatment of inhibiting uterine contractions,the increasing of maternal heart rate caused by ritodrine can be used as an indicator of therapeutic effect.

OBJECTIVE: To investigate the clinical features and operation treatment of the congenital middle ear cholesteatoma. METHOD: A retrospective review of clinical and surgical records of 10 patients with congenital middle ear cholesteatoma were performed. All patients were treated by surgeries,5 of 10 cases deal with one-stage tympanoplasty after drum exploration by external auditory meatus, 3 cases dealed with closed mastoidotympanectomy and tympanomastoidectomy, 2 cases dealed with open mastoidotympanectomy and tympanomastoidectomy. RESULT: The cholesteatomas were located at or around the posterior tympanum or mesotympanum in 5 patients, confined to the tympanic cavity and attic in 3 patients, advanced cholesteatoma that extended from the tympanic cavity into the mastoid antrum was seen in 2 patients. The mean postoperative PTA was 30 dB HL, the mean ABG was within 20 dB, after six months. No residual or recurrence of cholesteatoma was found. CONCLUSION The congenital cholesteatoma often originates from the posterior or anterior of the middle ear, with hiding lesion, thus result in severe conductive hearing loss. Imaging examination plays an important role in diagnosing and treating of congenital cholesteatoma. Early stage surgical treatment can obtain a good hearing reconstruction effect.

Liver innate immunity plays an important role in the defense against pathogen invasion.The mechanisms of liver innate immunity for defending against pathogen invasion are reviewed,including the special anatomical and physiological characteristics of the liver,the fea-tures of innate immune cells in the liver (liver-settled cells and cells raised from blood circulation)and their function and relationship with each other in pathogen invasion,the process of pathogen identification and effect of liver innate immune cells,and the mechanism of liver immune injury and immune tolerance.Given current research on innate immune cells and innate immune molecules in the liver,further stud-ies should be conducted to understand the connection and difference between liver innate immunity and systemic immunity,thus promoting the diagnosis and treatment of liver diseases and deeper research.

Objective To study the influence of blood glucose, blood lipids and other cerebral infarction risk factors in the mean platelet volume (MPV). Methods A total of 562 patients with cerebral infarction and type 2 diabetes mellitus (DM) and 216 cerebral infarction patients without DM (non-DM) were included in this study. The platelet parameter of peripheral blood and other laboratory indexes were detected including platelet count (PLT), MPV, platelet distribution width (PDW), plateletcrit (PCT), fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL-C), low density lipoprotein (LDL-C) and very low density lipoprotein (VLDL-C), urea nitrogen (BUN), creatinine (Cr), uric acid (UA), high-sensitivity C-reactive protein (hs-CRP) and homocysteine (HCY). The patients were scored by the National Institute of Health stroke scale (NIHSS) after hospitalization. The MPV changes in patients with cerebral infarction were observed, and different influences of blood glucose, blood lipids to MPV were analysed. Results Values of FBG, HbA1c, TC, TG, LDL-C, BUN, UA, HCY, hs-CRP, and NIHSS were significantly higher in DM group than those of non-DM group. The score of NIHSS was significantly higher in DM group than that of non-DM group. The level of HDL-C was significantly lower in DM group than that of non-DM grou. The MPV was significantly higher in DM group than that of non-DM group [(9.60 ± 1.35) fL vs. (9.27 ± 1.01) fL, P<0.05). There was a positive correlation between MPV and FBG, HbA1c, hs-CRP, WBC, VLDL-C and NIHSS, r=0.438, 0.410, 0.336, 0.164, 0.321 and 0.249 (P<0.05). Multiple regression analysis showed that FBG, VLDL-C, HbA1c, hs-CRP and NIHSS were the independent influential factors of MPV (P<0.05). Conclusion The influencing factors of MPV should be controlled in patients with cerebral infarction combined with type 2 diabetes mellitus, reducing the activation of platelet, and delaying the progress of cerebral infarction.
