Objective To change the traditional disposal of the third stage of labor, we exsanguinate the placental blood from the maternal termination of umbilical cord after delivery, then the pressure of placental sinus decrease rapidly, the vessels contract, the placenta seperate from the uterine wall and expuse quickly, the third stage of labor is shortened and postpartum bleeding amount is decreased. Methods We chose 200 cases of vaginal delivery puerperants from October 2004 to August 2005 in our hospital as the test group (group A), 100 cases of vaginal delivery puerperants in the same period as the control group (group B). The statistics of the third stage of labor and the postpartum bleeding amount is made so as to evaluate and analyse the effect. Results In group A, the third stage of labor is obviously shortened and the postpartum hemorrhage is obviously reduced. There is singnificant difference between the two groups (P
3.Studies on The Receptors of Botulinum Neurotoxins
Progress in Biochemistry and Biophysics 2006;0(02):-
Botulinum neurotoxin(BoNT) is the most lethal biotoxin known to mankind. It inhibits acetylcholinerelease from the cholinergic nerve ending by cleavage of SNARE proteins, followed by neuromuscular blockadeand paralysis. Gangliosides are considered to act as a first receptor of BoNT with low affinity.Then the membranebound gangliosides-BoNT complex moves laterally to reach and bind the toxin specific protein receptor,synaptotagmin, with a high affinity constant. At last the gangliosides-BoNT-synaptotagmin complex undergoesreceptor-mediated endocytosis. This double-receptors theory is widely accepted. The research data are summarizedand reviewed.

Objective To evaluate the role of clinical features,radiography and histopathology in differential diagnosis between chronic necrotizing pulmonary aspergillosis(CNPA)and aspergilloma.Methods Thirty-four patients including 8 cases of CNPA and 26 of aspergilloma comfirmed by operation and histopathology in First Affiliated Hospital,Zhejiang University were investigated retrospectively.The clinical manifestations,radiological and pathological findings of all the patients were analyzed and related references were reviewed. Results The age of onset was not significantly different between CNPA and aspergilloma.Obsolete pulmonary tuberculosis and lung abscess were predisposing factors of them.Productive cough was presented in all 8 cases of CNPA,haemoptvsis in 7,and 5 were presented with constitutional symptoms.The most common symptom of aspergilloma was haemoptysis, which was presented in 25 cases.The less common symptoms were cough and sputum,which was presented in 17 cases.Only two cases were presented with constitutional symptoms."Air crescent"sign at radiography was typical and suggestive of diagnosis in both CNPA and aspergilloma,but the wall of cavity in CNPA was thicker and irregular,infiltrates were often to be seen around the cavity.Histologically,CNPA and aspergilloma both showed septate fungal hyphae branching at an acute angle.CNPA was characterized with the presence of tissue invasion by aspergillus,tissue necrosis and granulomatous inflammation. Fungal hyphae ware only found in a preexistent cavity or ectatic bronchus without tissue invasion in aspergilloma.Conclusions Histopathology is gold standard of differential diagnosis of CNPA and aspergilloma. Meanwhile, clinical features and radiological findings appear to be valuable for the diagnosis.

Objective To find out social support status and its influencing factors in left-home-kids in rural areas. Methods 893 left-home-kids and 335 non-left-home-kids were interviewed with the social support rating scale. Results The total score of social support of left-home-kids was obviously lower than that of non-left-home-kids; in the same way, the score of female was higher than male, the score of low age group was higher than high age group, the score of kids with father or mother as the custodian was higher than that of other custodian subjects; the score of children whose left-home duration was more than five years was higher than that of lower than one year. Conclusions The social support of left-home-kids was poorer than non-lefthome-kids. There is some difference in the social support in left-home-kids with different sex, age, custodian subject, left-home duration. Social support should be given to children with low social support.
