Objective To investigate the effects of seed quality on the using value of Akebia trifoliata. Methods The seed net weight and plumpness were determined by electric balance, the moisture content was determined by moisture meter and the germination rate were determined through germination test. Results The seed net weight degree, 100-grain weight, 1 000 -grain weight, moisture content, viability, germination rate, and germination potential of A. trifotiata fresh seed were 98.7%, 6.64 g, 66.6 g, 43.1%, 94.5%, 82.6%, and 52.8%, respectively. Being made air-dried for 10 d or 60 d, the moisture content of A. trifoliata seeds were 28.5% and 7.8%, respectively, the germination rate were 64.3% and 14.7% respectively. Conclusion It is suitable to put the A. trifoliata seeds into the 30 ℃ clear water for 24 h and make them sprout or be buried in the wet sand at a room temperature of 5-12 ℃. When the moisture content of seed is lower than 8%, it will lose the value to be cultivated.

Objective To investigate the clinical feature,treatment and prognosis of both themother and the fetus with gestational diabetes insipidus.Methods A total of 7 cases of gestational diabetes insipidus collected in the First Affiliated Hospital of Wenzhou Medical College,Wen'zhou Combination ofTraditional Chinese Medicine with Western Medicine Hospital,and Zhejiang Taizhou Hospital from June 1993to June 2006 were analyzed retrospectively.Resuits Seven cases symptoms all characterized by excessive thirst polydipsia and polyuria.The average 24 h urinary output was between 11 L to 13 L and manifested of hypobaricuria.After effective treatment(three cases were treated with 1-deamino-8-D-arginine vasopressin,another three patients were managed with hydrochlorothiazide,and the last one was cured with antisterone),seven patients with gestational diabetes insipidus did not have any severe consequences.Their symptoms of excessive thirst,polyuria,and polydypsia disappeared from 7 days to 3 months after parturition.Urinary volume returned to normal standard of 1000-2000 ml during 24 hours.Specific gravity of urine recovered normally between a range 1.015-1.025 and serum sodium recovered between 135-147 mmol/L Theaverage duration of illness was 52 days.Eight newborn infants survived.Two of them were sent to neonatal intensive care unit for treatment.One was because of premature delivery caused by antepartum eclampsia,and the other case was one of the twins who had hydronephrosis.The baby of the first case left hospital after 3 weeks'treatment.The latter one's symptom disappeared 2 weeks after delivery.No obvious symptom was discovered among all the babies through follow-up telephone calls 42 days after childbirth.Conclusion Gestational diabetes insipidus is a rare endocrinopathy complicating pregnancy.This disorder is characterized by excessive thirst,polydypsia,polyuria,hypobaric urine and electrolyte disturbances usually manifesting in the third trimester of pregnancy or puerperium.This is a transient syndrome.The first treatment of choice in patients with gestational diabetes insipidus is 1-deamino-8-D-arginine vasopressin and the second-choice is hydrochlorothiazide.Early diagnosis and appropriate management of the disease may reduce the hazard forboth the mother and the fetus during perinatal period.

Objegtlve To study the effect of lipexins on the proliferation and secretion of peritoneal macrophages from patients with preeclampsia in vitro.Methods Peritoneal macrophages were obtained from 24 patients with preeclampsia(preeclampsia group)and 24 normal pregnant women(normal pregnant group)who were treated in the First Affiliated Hospital of Wenzhou Medical Coilege from March to July 2007.Enzyme linked immunosorbent assay (ELISA) was used to detect the concentration of tumor necrosis factor-α(TNF-α)in the supernatant of macrophages which were pulsed with lipoxins at different concentrations(0,10,100 nmol/L)in both groups after 48 hours.Methyl thiazolyl tetrazolium (MTT)assay was used to detect the inhibition rate of cell proliferation of macrophages which were pulsed with lipoxins at different concentrations(0,10,100 nmol/L)in both groups after 24 hours.Results (1)The concentration of TNF-α:the levels of TNF-α were(1867.5±47.3),(1836.9±4.5) and (1800.5±2.7)ng/L after treatment with differed concentrations of lipoxins(0,10,100 nmol/L)in preeclampsia group vs normal pregnant group[(791.3±62.2),(789.4±2.3),(781.5±1.9)ng/L].The levels of TNF-α in preeclampsia group were significantly higher than that in normal pregnant group(P＜0.05).Lipoxins significantly inhibited the concentration of TNF-α in a dose-dependent manner in preeclampsia group (P＜0.05),while it had no significant effect in normal pregnant group(P＞0.05).(2)Cell proliferation inhibition:Incubation with lipoxins produced a dose-dependent(0,10,100 nmol/L)inhibitory effect on proliferation in preeclampsia group,[(14.8±6.3)%,(32.9±3.6)%,(36.7±3.8)%],vs normal pregnant group[(16.8±6.9)%,(16.7±5.4)%,(15.9±2.1)%].The rate of cell proliferation in preeclampsia group was significantly hisher than that in normal pregnant group.Lipoxins significandy inhibited this growth(P＜0.05),while it had no significant effect in normal pregnant group(P＞0.05).Conclusion Lipoxins can inhibit the proliferation of macrophage and secretion of TNF-α in preeclampsia in a dose-dependent manner.Lipoxins may be potentially useful in prevention and treatment of preeclampsia.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
