RESUMO
Objective:To investigate the therapeutic value of modified multipoint drainage for biliary complications after liver transplantation.Methods:A total of 125 patients treated by endoscopic retrograde cholangiopancreatography (ERCP) for biliary complications after liver transplantation in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from May 2018 to May 2020 were enrolled. Patients were divided into endoscopic retrograde biliary drainage (ERBD) group ( n=67, treated with multiple drainage of bile duct stent) and modified multipoint drainage group [ n=58, treated with ERBD combined with endoscopic nasobiliary drainage (ENBD)] by random number table. Modified multipoint drainage group were further randomly divided into two groups, modification group 1, 31 cases, where nasobiliary ducts were cut proximal to duodenal papilla after one week under endoscopy and modification group 2, 27 cases, where they were cut proximal to duodenal papilla after two weeks under endoscopy. The changes of serological indexes in 2 weeks after the operation in three groups were compared, and the incidence of short-term and long-term complications were analyzed. Results:The serological indexes were improved in patients at 1 d, 7 d and 14 d after ERCP, especially in modified multipoint drainage groups. Two weeks after the operation, the improvement of serological indexes in modification group 2 was better than that in modification group 1. Incidence of recent complications including cholangitis, hyperamylasinemia, and pancreatitis in the ERBD group were higher than those in modification group 1 [32.84% (22/67) VS 12.90% (4/31), 46.27% (31/67) VS 19.35% (6/31), 20.90% (14/67) VS 3.23% (1/31), all P<0.05] and modification group 2 [32.84% (22/67) VS 11.11% (3/27), 46.27% (31/67) VS 22.22% (6/27), 20.90% (14/67) VS 3.70% (1/27), all P<0.05]. ERBD group had a higher incidence of long-term complications including recurrent biliary infection and jaundice than modification group 1 [ 58.21% (39/67) VS 35.48% (11/31), P=0.036; 49.25% (33/67) VS 25.81% (8/31), P=0.027] and modification group 2 [58.21% (39/67) VS 11.11% (3/27), P<0.001; 49.25% (33/67) VS 25.93% (7/27), P=0.038]. The incidence of recurrent biliary infection in modification group 1 was higher than that in modification group 2 [35.48% (11/31) VS 11.11% (3/27), P=0.030]. Conclusion:Multiple drainage with indwelling nasal bile duct by ERCP can effectively reduce the short-term and long-term complications and improve the recovery of serological indexes for patients with biliary complications after liver transplantation. It is suggested that the nasobiliary duct should be retained for 2 weeks and then transformed into a built-in tube to continue drainage.
RESUMO
Objective To explore the expression and the pathomechanism of folate receptor alpha(FRα) and CA125 in the development and progression of endometrial carcinoma.Methods Sixty samples of endometrial carcinoma tissues,46 samples of endometrial hyperplasia tissues and 10 normal endometrial tissues were collected in the study.Immunohistochemical methods were used to detect the expression of Frαand CA125 in all tissues.The expressions of FRα and CA125 and their correlation with clinicopathological characteristics were analyzed.Results FRα was positively expressed in 93.9％ of the endometrial carcinoma tissues,with a strongly positive rate of 65.0％,which was significantly higher than that in endometrial hyperplasia tissues and normal endometrial tissues (P ＜ 0.05).The highly expressed FRαin endometrial carcinoma tissues was associated with age,FIGO stage and histologic types (P ＜ 0.05),while no statistical significance was found between the high expression of FRαand myometrial invasion.The expression of FRα in endometrial atypical hyperplasia was higher than that in other hyperplasia subgroups.The expression of CA125 in endometrial carcinoma tissues and endometrial hyperplasia tissues were both higher than that in normal endometrial tissues (P ＜ 0.05).Conclusion FRα may play an important role in the carcinogenesis and progression of endometrial carcinoma,and act as a target of therapy and a kind of assessment for prognosis in endometrial carcinoma.CA125 may be involved in the development of endometrial lesions and further researches are needed to confirm a physiological mechanism between FRA and CA125 in carcinogenesis of endometrial carcinoma.
RESUMO
Objective To detect serum concentration of folate receptor alpha and to investigate its significance in the clinical application of patients with endometrial carcinoma. Methods Thirty-seven patients with endometrial carcinoma, 33 patients with endometrial hyperplasia and 10 healthy women were enrolled in this study. Sera were used to detect the the folate receptor alpha using an Enzyme-linked Immunosorbent Assay (ELISA) technique.The expression level of serum folate receptor alpha in different groups was analyzed. The correlation between the expression level of serum folate receptor alpha and age of patients, menopause, tumor morphology, myometrial invasion and clinical stage was was also analyzed in patients with endometrial carcinoma. Results Level of folate receptor alpha was successfully detected in serum of healthy women and patients with endometrial diseases. Level of folate receptor alpha in patients with endometrial carcinoma was much higher than that in patients with endometrial hyperplasia. Level of folate receptor alpha in patients with endometrial hyperplasia was also higher than that in the healthy controls, with significant difference (P 0.05). Conclusion The Serum level of folate receptor alpha can be detected, and its expression will contribute to the diagnosis, treatment and predicting the prognosis of patients with endometrial carcinoma.
RESUMO
Objective To investigate spatial memory ability of intraperitoneal injection of resveratrol in a mice model of chronic constriction injury of sciatic nerve(CCI).Methods Forty-four C57BL/6 mice were divided randomly into 4 groups:sham group (n=14),CCI group (n=14),resveratrol pre-treatment group (i.p.resveratrol 100 mg/kg 30 minutes before CCI model,n=8) and resveratrol post-treatment group (i.p.resveratrol 100 mg/kg 14 days after CCI model,n =8).CCI group,resveratrol pre-treatment group and resveratrol post-treatment group were operated with the model of neuropathic pain induced by chronic constriction injury of sciatic nerve.In shamoperated controls,an identical surgical procedure was performed,except that the sciatic nerve was not ligated.This was accomplished by using intellicage for mice by newbehavior to record their spatial memory after surgery.Results (l) Resveratrol pre-treatment group showed improved spatial memory ability compared with sham group and CCI group during day 17-21 (17 d:(55.80±7.66) ％,(51.20±7.94) ％ ; 18 d:(60.20±3.89) ％,(49.80±8.61) ％ ; 19 d:(62.20±7.25) ％,(51.20±6.83) ％ ;20 d:(63.00±9.69) ％,(48.40±8.84) ％ ;21 d:(56.80±7.52) ％,(47.20±4.54) ％)(P＜0.05),compared with CCI group.(2)From day 26,the spatial memory damage was observed in mice with CCI (26 d:(37.50±5.50)％,(51.80±9.01)％;27 d:(37.25±4.19)％,(51.20±5.76)％;28 d:(42.25± 3.50) ％,(52.80± 7.52) ％) (P＜ 0.05),compared with sham group.And this damage could be reversed by resveratrol,which was injected when the chronic pain was stable (26 d (46.60± 5.27) ％,27 d (54.00± 7.31) ％,28 d (52.60±4.39)％),compared with CCI group(P＜0.05).Conclusion Chronic constriction injury of sciatic nerve mice due to spatial memory impairment can be improved by resveratrol.
