Objective To study the urodynamic characteristics of women with pelvic organ prolapse in prolapse and reset condition. Methods From Jan. 2010 to Apr. 2010, 30 patients with pelvic organ prolapse (POP), including 1 case in grade Ⅰ , 6 cases in grade Ⅱ , 21 cases in grade Ⅲ and 2 cases in grade Ⅳ, treated in Peking University People's Hospital were analyzed their urodynamical changes at status of prolapse and reset with pessary. Results (1)The symptoms: in the prolapse condition, there were 11 patients with bladder outlet obstruction( BOO), 7 patients with residual volume more than 100 ml, and 4 patients with stress urinary incontinence(SUI). In the reset condition, there were 5 patients with BOO,5 patients with residual volume more than 100 ml, and 4 SUI patients. (2) Characteristics of urodynamic:there were significant difference in first desire to void ( FD, P = 0. 047), normal desire to void ( ND, P =0. 007), strong desire to void ( SD, P = 0. 001 ), maximum cystometric capacity ( MCC, P = 0. 001 ),maximum flow rate ( Q=max, P = 0. 001 ), average flow rate ( Q P = 0. 001 ), and residual volume ( RV,P = 0. 025 ) between prolapse and reset condition among all patients. In patients with grade Ⅰ to Ⅱprolapse, Qmax were (11 ±6) ml/s in prolapse condition and (15 ±4) ml/s in reset condition (P =0. 014), Qave were ( 6 ± 4 ) ml/s in prolapse condition and ( 7 ± 3 ) ml/s in reset condition ( P = 0. 237 ),RV were (29 ±46) ml in prolapse condition and (15 ±25) ml in reset condition (P =0. 157). Among patients with grade Ⅲ to Ⅳ prolapse, Qmax were ( 11 ± 8 ) ml/s in prolapse condition and ( 17 ± 10) ml/s in reset condition (P=0.001), Qave were (5 ±4) ml/s in prolapse condition and (7 ±4) ml/s in reset condition ( P = 0. 002 ), RV were ( 105 ± 169 ) ml in prolapse condition and (47 ± 92) ml in reset condition (P = 0. 037 ). Conclusions Patients with pelvic organ prolapse Ⅲ - Ⅳ may present pseudo BOO,recessive stress urinary incontinence and residual volume more than 100 ml. There were significant improvement in cystometric sensation, capacity, flow rate, and residual volume after reset. The urodynamic test for patients with pelvic organ prolapse in the reset condition might be much better in evaluating lower urinary tract function.

Objective To investigate the clinical characteristics, the antenatal management, the outcome and prognosis of chronic myeloproliferative disorders (CMPD) complicating pregnancy. Methods Retrospectively analyze the clinical data of eleven patients with CMPD complicating pregnancy hospitalized in Peking University People' s Hospital from 2000 to 2009, including five patients with essential thrombocythemia, one with primary myelofibrosis and five with chronic myeloid leukemia. Results (1)Five pregnancies had periodic antenatal care and laboratory monitorings like full blood count. Reasonable anti-coagulation therapy was given to prevent the complications. One patient with PMF diagnosed before conception had her first pregnancy ended with mild pre-eclampsia and intrauterine death at the gestational age of 32 weeks. During the first trimester of her second pregnancy two years later, the test for anti-β2 glycoprotein antibody was positive. She received low-dose aspirin and low-molecular-weight heparin as anticoagulants. An uneventful course was obtained and she delivered a healthy term infant. (2) Five pregnancies had occasional antenatal examination, including two patients with ET and three patients with CML One patient with ET developed severe pre-eclampsia at the gestational age of 25 weeks. Umbilical artery Doppler showed reversed end-diastolic velocity. The management with anti-convulsants, antihypertensives and anti-coagulants showed no effect. An emergency cesarean section had to be performed because of the aggressive hypertension and placental abruption, with still birth as a result. Two pregnancies never had an antenatal care. Both of them were admitted on labor and the diagnoses of CML were made. (3)Four pregnancies developed oligohydramnios and three developed preelampsia(two severe pre-eclampsia and one mild pre-eclampsia). There was no other hemorrhage and thrombosis event. (4) Eight pregnancies reached full-term with four cesarean sections and four vaginal births. Two preterm cesarean sections were performed because of a progressive oligohydramnios. The ten live neonates weighed 1820 - 3600 g. All were appropriate for gestational age, except one fetal growth retardation (FGR) developed in one patient with severe pre-eclampsia. (5) As for the CMPD, the eleven patients were all in stable conditions. Three patients with CML received hydroxyurea in the third trimester, four with ET and one with CML had plateletpheresis before delivery with favorable effect. All patients were uneventful postpartum, except one with CML who died in 5 months after childbirth. Conclusions The pregnancy outcomes for patients with CMPD are mostly good. However, antenatal care should pay more attention to the complications such as thromboembolic accidents, pre-eclampsia, still birth and fetal growth retardation. Management including reasonable anticoagulation therapy should be considered, which may help improve the prognosis.

This article was aimed to study the immunomodulatory effect of ethanol sediments of the seeds of Descurainia sophia(L.) Webb. ex Prantl. both in vitro and in vivo. The lymphocyte proliferation test in vitro was carried out to explore the effect of the ethanol sediments on the proliferation of T cell and B cell in the spleen of normal mice. And, the carbon clearance test, serum hemolysin test, and delayed-type hypersensitivity test were used to investigate the influence of fraction on non-specific immunity, humoral immunity and cellular immunity in the immunosuppressive mice induced by cyclophosphamide. Besides, the immunosuppressive model was used to evaluate the effect of fraction on immune organs and content of cellular factors in blood serum. The results showed that the ethanol sediments promoted Concanavalin A (Con A) induced T cell and Lipopolysaccharides (LPS) induced B cell (P < 0.01). It increased the carbon clearance index K, phagocytic index α, half value hemolysis (HC50), and swelling degree of auricula (P < 0.05 or P < 0.01). It reduced the body weight and atrophy of thymus and spleen index (P < 0.05 or P < 0.01). It increased the contents of IL-2, IFN-γ and IL-4 in serum in immunosuppressive mice (P < 0.05 or P < 0.01). It was concluded that ethanol sediments of the seeds of D. sophia(L.) Webb. ex Prantl. can boost the lymphocyte proliferation, protect the immune organs, and enhance the non-specific and specific immunity in immunosuppressive mice, which indicated that it had immune-promotion effect.

This article was aimed to study immunomodulatory effect of chemical split fractions ofMori Cortex, in order to initially explain effective parts that played a role in immunomodulatory effect ofMori Cortex. The carbon clearance test, serum hemolysin test, E-rosette test, and lymphocyte transformation test were carried out to explore influence of these chemical split fractions ofMori Cortex on immune organs, nonspecific immunity, humoral immunity and cellular immunity. The results showed that in the carbon clearance test, 50% ethanol fraction markedly reduced the thymus index (P<0.01) and the correction indexα (P<0.05). In hemolysin test, the half value hemolysis (HC50) was improved by 30% ethanol fraction and fatty oil fraction (P<0.05). Besides, in the E-rosette test, the E-rosette ration was increased in the 30% ethanol fraction group (P<0.05). In the lymphocyte transformation test, the 30% ethanol fraction can promote the thymus and spleen lymphocytes proliferation (P<0.05 orP<0.01), while the 50% ethanol fraction inhibited the proliferation (P<0.05 orP<0.01). It was concluded that the 30% ethanol fraction can boost both the humoral immunity and cellular immunity; the 50% ethanol fraction can induce the growth of thymus with a suppressive effect on nonspecific immunity and cellular immunity; the fatty oil fraction can improve humoral immunity.
