Objective To evaluate the treatment of surgery and high-dose corticosteroid relevant factors to prognosis in traumatic optic neuropathy. Methods Forty patients(40 eyes) with traumatic optic neuropathy were enrolled.Optic nerve decompression using transcranial approaches,sinus endoscopy and orbital-ethmoidal sinus rout were performed in 14 patients.Eleven patients were treated with high-dose corticosteroids (5 cases with 1 mg/kg dexamethasone,6 cases with 30 mg/kg methylprednisolone) and 15 patients received nonspecific management chose by themselves.The outcomes of visual acuity in short term and final stage were compared between surgery,high-dose corticosteroid and nonspecific treatment.Multiple variable analysis was done to determine the factors affecting the outcome of visual acuity. Results No light perception were found in 19 cases (19 out of 44 cases,47.5%),whereas visual acuity was light perception to 0.02 in 12 cases (30.0%) and 0.05 or better in 9 cases (22.5%).The odds ratio of high-dose corticosteroid to nonspecific therapy was 2.96 (P=0.0125).The final visual acuity in patients treated with high-dose corticosteroid were better than other two groups (P=0.005,P=0.023,respectively).The short term (within 3 days) effective rate was higher in corticosteroid therapy group than operated group (P=0.024).No light perception following optic nerve trauma appeared to be more danger as 2.14 folds (P=0.0349) than those with light perception or better in term of final visual acuity outcome. Conclusions High-dose corticosteroid may be benefit to traumatic optic neuropathy.The treatment in traumatic optic neuropathy using optic nerve decompression needs to be determined.No light perception at initial is an important risk factor in the outcome.

ObjectiveTo explore the association between paroxetine (Seroxat) and level of blood sugar and endocrine hormones in pre-diabetes patients with anxiety and depression. MethodsFifty-four pre-diabetes patients with anxiety and depression diagnosed from January 2010 to December 2012 were recruited. The self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to assess depression and anxiety. All the patients were treated by paroxetine. The glucose tolerance test (OGTT), ACTH and cortisol were tested in patients at baseline and within 24 weeks. ResultsAfter 24 weeks' treatment, the level of anxiety and depression as well as the OGTT 0.5 h (0.5 h PG), OGTT 1 h (1 h PG), OGTT 2 h (2 h PG), glycated hemoglobin (HbA1c), adrenocorticotropic hormone (ACTH) and cortisol were significantly decreased (P<0.05 or P<0.01). The glycated HbA1c had a positive correlation with adrenocorticotropic hormone (ACTH) and cortisol (F). Before and after treatment, the reduced rate of ACTH and reduced rate of cortisol respectively exhibited a positive correlation with the reduced rate of HbA1c, reduced rate of SAS and reduced rate of SDS. ConclusionAnti-anxiety depression treatment can lower blood sugar level in pre-diabetes patients with anxiety and depression significantly, which may be related to the activity of HPA axis.

ObjectiveTo summarize the clinical and imaging features of hepatic adrenal rest tumor and to explore its tissue source, diagnosis, differential diagnosis and treatment.MethodsThe clinical data of patient with hepatic adrenal rest tumor in the West China Hospital of Sichuan University were analyzed retrospectively. The diagnostic methods of liver adrenal junction were summarized by consulting relevant literatures.ResultsThe patient was admitted to the hospital with right hepatic lesions. The preoperative imaging examination showed that it was the imaging features of hepatocellular carcinoma. The right hemihepatectomy was proposed. During the operation, it was found that the lesions were not from the liver, but from the retroperitoneum (The possibility of adrenal origin was very high). Then, the retroperitoneal occupying lesions was completely resected via urology surgery consultation. The pathological results showed that the tumor was adrenocortical carcinoma.ConclusionsIt is very difficult to accurately diagnose nature of hepatic adrenal rest tumor before operation only by results of cross-sectional imaging, especially for some adrenal tumor. It needs to fully be evaluated and even to perform multidisciplinary discussion if necessary for patients who have hepatic adrenal rest tumor before operation, so as to avoid misdiagnosis to a certain extent.
PURPOSE:To evaluate the activitv of protein kinase C(PKC) in response to retinal photochemical insult in rat. Furthermore, to investigate the effect of dexamethasone(DXM ) on PKC activity. METHODS :The experiments were performed on 48 SI') rats whieh were separated into two groups,control and treated groups,and the latter received daily intraperitoneal injections of DXM (1 mg/kg)for 5 consecutive days,starting 3 days before light exposure. The animals were continually exposed to green fluorescent light (510nm~560nm) with an illuminance level of (1 900plusmn;106.9)lx for 24 hrs.The retinal enzyme activity of PKC was tested at 6 hrs,1 day,3 days,7 days,and 14 days after light exposure respectively. RESULTS:In animal models,PKC activity showed a transient increase in both groups at 6 hrs after light exposure and then decrease persistently there alter. The activity of PKC was unresponsive to DXM intervention. CONCLUSIONS :These results suggested that the persistent lower PKC activity might result in disturbance of retinal function in rat retinal photochemical injury. （Chin J Ocul Fundus Dis,1997,13: 78-80）
To report a case of a 1-year-old female child admitted to the hospital with recurrent convulsions and diagnosed as West syndrome, also known as infantile spasms (IS). The child had been experiencing convulsions for 4 months prior to admission, characterized by forward head tilt and flexion of the limbs, with 8 ~ 10 episodes per day. After admission, West syndrome was identified by EEG and imaging evaluation, and adrenocorticotropic hormone (ACTH) shock therapy was started on day 5 of admission, supplemented with peripherally inserted central catheter (PICC), gastric protection, calcium and potassium supplementation and other supportive measures. During the course of treatment, the nursing team implemented meticulous monitoring and assessment to ensure that the child's vital signs were stabilized, and potential side effects were detected and treated in a timely manner. After 14 days of treatment, the child had no further spasticity episodes during 3 ~ 14 days, and was discharged from the hospital with continued oral hormone intake and regular follow-up. During the nursing process, the nursing staff provided psychological support and education to the child and her family to help the family understand the disease and enhance their ability to manage it. In addition, personalized nutritional support and monitoring were provided to ensure the healthy growth of the child. The successful management of this case not only enhanced the quality of clinical care, but also provided useful reference and inspiration for similar cases.
Relative/absolute adrenal insufficiency is not uncommmon in the patients undergoing cardiovascular surgery with cardiopulmonary bypass. However, this complication was rarely reported due to its unspecific clinical presentations and the unawareness of ICU physicians and cardiac surgeons. However, this puts them on a higher risk of hemodynamic instability and cardiovascular adverse events during hospitalization. Systematic reviews concentrated on it are rarely reported currently. We aim to review the etiology, risk factors, potential pathogenesis and related research progress for this complication.
Objective To investigate the relationship among rats′ stress ulcer and gastric acid, prostaglandin (PGs) and adrenocorticotropin (ACTH) and to probe the pathogenesis, prophylaxis and therapy. Methods Rats′ stress ulcer model was made by cold water soaking and was properly treated with drugs such as hyoscine, dexamethasone, ranitidine and losec. The amount and pH of gastric juice, change of gastric mucosa and PGs and ACTH of blood were determined. Results After rats were fasted for 24 hours a little gastric juice was aspirated. After cold water soaking of rats gastric juice was increased with the pH decreased, there was gastric mucosal bleeding, blood PGs was decreased and ACTH was increased. These suggest that on stress gastric mucosa bleeding is related with decreased gastric juice pH, decreased PGs and increase ACTH.Conclusion To control stress ulcer, pH of gastric juice and amount of PGs should be increased. Losec can increase gastric juice pH, so losec is the first choice to control stress ulcer.
