AIM: To observe the changes of plasma content of Glu-plasminogen (plasmin, Pln) in patients during blood coagulation and/or fibrinolytic system activation. METHODS: Using specific McAb to antigenic determinant in NH 2 terminal (1-65 aa) of Pln and specific McAb to antigenic determinant in heavy chain of plasminogen, the sandwiched ELISA method was established to detect Glu-plasminogen and total plasminogen in human plasma collected from 220 normal controls and 40 patients after heart surgery. RESULTS: The average total plasminogen was (231.8?62.1) mg/L and average Glu-plasminogen was (231.9?45.8) mg/L in 220 normal controls, the ratio of Glu-plasminogen to total plasminogen (G/P) was 0.91. The ratio of Glu-plasminogen [(152.4?68.1) mg/L] to total plasminogen [(268.9?73.3) mg/L] in 40 patients after heart surgery was significantly lower than that in normal controls ( P

AIM:To analyze the effect 17?-estradiol on activated macrophages and possibility of being a target of screening drugs for endometriosis. METHODS: Using scanning electron microscope, the surface of macrophages was observed. Nitric oxide (NO) in supernatant was determined by Griess's reagent. TNF-? was measured by MTT via L929 cells. Using Fluo-3/AM, i was measured by laser scanning confocal microscopy (LSCM). RESULTS: (1) Increased size, extension of more microvilli, expression of retraction fibers and elaboration of membrane ruffles were detected in 17?-estradiol treated macrophages. (2) 17?-estradiol induced NO release from peritoneal macrophages. (3)The more TNF-? was made by macrophages under the induction of 17?-estradiol. (4)Intracellular Ca 2+ elevated 39.8% in peritoneal macrophages after 17?-estradiol (100 nmol/L) treatment. CONCLUSIONS: Macrophages were activated by 17?-estradiol at a certain concentration. Activated macrophages by 17?-estradiol may participate in endometriosis and may be a target of screening drugs for endometriosis.

Objective To evaluate the diagnostic value of the recombinant protein Sj_Ts4 in immunodiagnosis of Schistosomiasis japonica.Methods Seventy-four blood samples of schistosomiasis japonica patients(acute, chronic and advanced)were used for evaluating the sensitivity.Blood samples from 24 Clonorchiasis patients,8 patients with hookworm infections and 30 normal persons from the areas without Schistosomiasis were used ror patients.Results The positivity rates were 97.1%(33/34),100.0%(16/16),87.5%(21/24)in rSj-Ts4-ELISA and 100%(34/34),100.0%(16/16),75.0%(18/24)in SjAWA-ELISA in acute,chmnic and advanced Schistosomiasis. respectively.Statistical analysis revealed no significant difference in sensitivity(X2=1.23,P＞0.05)between both recombinant and crude antigens.The false positive reaction was found to be 6.7%(2/30)in rSj-Ts4-ELISA and 3.3%(1/30)in SjAWA-ELISA when detected in 30 cases of normal control sera.but no statisticallv significant difference was noted(x2=0.35,P＞0.05).Twelve point five percent(3/24),20.8%(5/24)and 12.5%(1/8),37.5% (3/8),of cross-reactions were observed between rSj-Ts4-ELISA and SjAWA-ELISA for detecting the sera of patients with clonorehiasis and hookworms.There was no significant difference of cross-reaction in two parasitic infections (x2=0.60,1.33,P＞0.05)with the two tests.Conclusions The rSj-Ts4 antigen shows higher sensitivity and specificity for the diagnosis of Schistosomiasis japonica,which is helpful in the serological diagnosis of Schistosomiasis japonica in endemic areas.

Objective To investigate the change of indications of emergency obstetric hysterectomy and the clinical application of intraoperative interventions. And to provide evidence for prevention of hysterectomy and improvement of obstetric quality. Methods Clinical data were collected from 97 patients who received emergency obstetric hysterectomy at Shengjing Hospital of China Medical University between January 1st, 2004 and December 31st, 2013. The patients were divided into two groups by the time point of January 1st, 2009: the first group was cases treated between January 1st, 2004 and December 31st, 2008, while the second group was cases treated between January 1st, 2009 and December 31st, 2013. The clinical indicators, surgical indications, intraoperative interventions, and blood loss between the two groups were analyzed retrospectively. Results (1) Incidence:54 857 women delivered at Shengjing Hospital of China Medical University between January 1st, 2004 and December 31st, 2013. Of them, 97 patients received emergency obstetric hysterectomy, with an incidence of 0.177% (97/54 857). (2) The 17 patients delivered vaginally (18%,17/97) and 80 by caesarean section (83%,80/97). Forty-nine patients experienced repregnancy with scar uterus (51%, 49/97). About 41 patients underwent abdominal total hysterectomy (42%,41/97) and 56 received subtotal hysterectomy (58%,56/97). (3) The number of patients were comparable between the two groups (50 vs 47;P>0.05). (4) The main surgical indication was uterine inertia (45%, 44/97). The main causes of uterine inertia were excessive uterine tension (45%, 20/44) and placental abruption due to gestational hypertension (32%, 14/44). Of all the indications, 29 patients in the first group (58%, 29/50) and 15 patients in the second group (32%, 15/47) suffered from postpartum hemorrhage. Pathological placenta embedment occurred in 15 patients in the first group (30%, 15/50) and 25 patients in the second group (53%, 25/47). The incidences of postpartum hemorrhage due to uterine inertia or pathological placenta embedment were significantly different between the two groups (both P<0.05), respectively. (5) In the first group, the average preoperative blood loss was (2 900±1 900) ml, and the average intraoperative amount of infused white&red blood cells was (5.9±3.5) U, with the average operation time of (2.2 ± 1.8) hours and the average in-hospital duration of (7.8 ± 2.3) days. In the second group, the average preoperative blood loss was (3 100± 2 200) ml, and the intraoperative amount of infused white&red blood cells was (6.2± 5.2) U, with the average operation time of (2.5± 2.1) hours and the average in-hospital duration of (7.9 ± 2.9) days. There was no significant difference between the two groups in any of these indicators (P>0.05). Postpartum hemorrhage was usually treated with uterine packing in the first group, but was preferentially treated with potent uterine contraction agents, arterial ligation, uterine balloon compression or B-Lynch suture in the second group. The therapeutic effects of these new treatments were significantly better than uterine packing (P<0.05). Conclusions The incidence of emergency obstetric hysterectomy did not change significantly in the past decade. However, the indications and intraoperative interventions have changed significantly in the second five years compared with the first five years. The main surgical indications were uterine inertia and postpartum hemorrhage due to pathological placenta embedment. Therefore, strict control of caesarean section indications was important to reduce emergency obstetric hysterectomy.
