G3BP (Ras-GTPase-activating protein SH3 domain binding protein), a protein which binds to RasGAP SH3 domain, belongs to RNA-binding protein family, implicating in the downstream of Ras signaling. G3BP harbors the activities of endoribonuclease and DNA helicase, and can induce stress granules formation. G3BP plays a general role in the signal pathways of cell proliferation, differentiation, apoptosis and RNA metabolism. It has been shown to be over-expressed in a number of human malignancies and has a close relationship with tumor invasion and metastasis. Given that it has been implicated in several pathways that are known to be involved in cancer biology, G3BP may provide a new target for cancer therapy.

Atropine has been an effective drug antagonizing M-like symptoms induced by severe acute organophosphate pesticide poisoning (AOPP), which could relieve bronchospasm, inhibit glandular secretion, and prevent pulmonary edema. In the rescue of severe AOPP, a hypo-dose of atropine is difficult to effectively block the effect of acetylcholine, and overdose plays great risk of atropine poisoning. When the patient's condition improves, the rebound often occurs in the process of withdrawal. Medical workers at home and abroad have conducted a lot of study to explore the personalized judgment of atropinization and optimal treatment of atropine for severe AOPP, including the initial bolus of atropine,the sustained infusion for the treatment of pulmonary edema, the maintenance dose, extenuation and withdrawal of atropine for the prevention of its overdose. Related researches in recent years were reviewed to provide the clinical reference.

AIM:To observe the preliminary efficacy of conbercept injected intravitreally for the treatment of wet age-related macular degeneration(wAMD).METHODS:Seventeen wAMD patients (18 eyes) were selected to receive conbercept injection.All patients were given a single conbercept injection every month,3 times.Before and after 1,2,3mo of the injection,the best corrected visual acuity (BCVA),intraocular pressure (IOP,measured by Non-contact tonometer),fundus photography,fundus fluorescein angiography(FFA),indocyanine green angiography(ICG),optical coherence tomography(OCT) examination and the complications incidence were compared.RESULTS:Three months after conbercept injection,the BCVA improved in 15 eyes (83%),stable in 3 eyes (17%).Before treatment,the average central macular thickness was 421.72±54.43μm,at 1 and 2 and 3mo after treatment,the average central macular thickness was 337.89±25.88μm,293.56±26.87μm,266.89±19.10μm respectively.There were significant differences compared with before and after injection(P<0.05).In the final follow up,FFA and ICG showed that the leakage in macular area disappeared in 15 eyes (83%),still existed in 3 eyes (17%),in those 3 eyes the injection was given for one or two times till the leakage disappeared.Elevated intraocular pressure occurred in 2 cases (26mmHg,23mmHg),after 1d down to normal.Another patient showed postoperative envy,given left ofloxacin eye drops after 2d,then back to normal.There was no serious ocular adverse reactions.CONCLUSION:Intravitreal injection conbercept for wAMD can significantly improve the visual function,reduce the macular edema and the leakage with higher safety and less complications.However the prolonged efficacy needs further observation.

Objective To study the types of autoantibodies in patients with primary biliary cirrhosis.Methods There were 60 patients with primary biliary cirrhosis from January 1995 to December 2004 in People's Hospital. We analyzed those patients' autoantibodies results and clinical data.Results There were 75% patients with anti-mitochondrial antibody(45/60),and antinuclear antibodies were detected in 60%(36/60)PBC patients,with the following hierarchy of specificities:23%(14/60)speckled,20%(12/60)multiple nuclear dots,16%(10/60)nuclear membranous,6%(6/60)anti-centromere,1.6%(1/60)homogeneous,20%(12/60)anti-SSA,10%(6/60)anti-SSB and 1.6%(1/60)anti-RNP. Several patients showed multiple specificities. Comparing PBC patients with or without AMA,no statistically significant difference was found on ages,biochemical and immunological parameters.Conclusion AMA-negative PBC patients share the same clinical features with AMA-passive PBC. Except for AMA,other antibodies may present in PBC patients. Multiple nuclear dots and nuclear member antinuclear antibodies may be helpful for diagnosing PBC patients without AMA.

Objective To evaluate the diagnostic and differential value of triphasic, especially the arterial phase, contrast enhanced CT scans for the hepatocellular adenoma, and to improve CT diagnostic accuracy. Methods Spiral CT scanning of pre and post contrast arterial phase, portal venous phase and delayed phase was performed in 5 patients with hepatocellular adenomas proved surgically and pathologically. The enhancement was administrated with venous injection of 3 ml/sec, totally 100 ml angiografin. Arterial phase of contrast enhanced scanning started 20～30 sec, portal venous phase 60～70 sec and delay scanning 3 min after the injection of contrast medium. The degrees of the enhancement of adnoma and normal tissues of liver in the three contrast enhanced phases were calculated and compared statistically. Results In plain CT, the lesions were iso density in 4 cases and slight hypodensity in 1 case, which was hardly distinguished from the normal tissue. In all 5 cases, the lesions showed marked enhancement in the arterial phase compared with normal tissue of liver (38 HU high), and there were markedly statistical difference ( t =18 94, P 0.05). The mean CT value of hepatocellular adenoma in the arterial phase was much higher than that in portal venous and delay phase, there were statistical differences between them ( F =18.39, P

Objective To investigate the characteristics of marital quality and social support status of the patients with breast cancer during the period of chemotherapy and the correlation of both factors.Methods Seventy-seven patients with breast cancer were divided into beginning-, middle-and final-staging groups of chemotherapy.And they were studied with Olson marital quality questionnaire and Social Support Rating Scale.Results The total scores of marital quality and other factors were the lowest in the mid-chemotherapy group.Among three groups,the mean of the objective support and availability were gradually increased with the chemotherapy going.The score of objective support was higher in the final than beginning chemotherapy groups (P =0.009).There was a positive correlation between marital satisfaction and the objective support (r =0.248, P =0.036), and between the total score of quality of marriage and subjective support (r =0.286, P = 0.015).Conclusion The marital quality of breast cancer patients receiving chemotherapy is poor,and subjective or and objective support might improve the patient's marital quality.

Objective To evaluate the clinical pathway (CP) for treatment of hepatic cystic echinococcosis.Methods Data were retrospectively obtained from hospitalized patients with hepatic cystic echinococcosis (CE) who were treated surgically between April 2011 to December 2012.Patient treated with the clinical pathway (the CP group) were compared with patients who were treated with conventional treatment (the non-CP group).The following outcomes were compared:the average length of in-hospital stay,the hospital charges,patient's satisfaction,patient's knowledge about his/ her own health and postoperative complications.Results For the CP groups,the length of in-hospital stay,the hospital charges,the patient's satisfaction and the health knowledge for the patients were (10.25±1.26)d,(19600.25±1520.73) yuan,(46.4 5±2.14),(83.50±8.02),respectively.The corresponding figures for the non-CP group were (14.25 ± 1.50) d,(23931.25 ± 1629.17) yuan,(42.65 ± 1.93),(74.50 ± 12.60),respectively.There were significant differences between the 2 groups (t=-4.086,-4.074,8.351,3.811 ; P＜0.05).The postoperative complications,including bile leakage,bleeding,ascites and pleural effusion,were 2,0,2 cases in the CP group,and 0,4,5 cases in the non-CP group.There were no significant difference between the 2 groups (x2 =0.17,0,0.6; P＞0.05).Conclusion Our initial clinical experience showed that the clinical pathway decreased the length of in-hospital stay and hospital charges,and provided quality and efficient clinical services to patients with hepatic cystic echinococcosis.
