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.

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.
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.
Objective To investigate the clinical features, diagnosis, treatment and prognosis of ectopic adrenocorticotropic hormone (ACTH) syndrome caused by bronchopulmonary carcinoid. Methods Twenty patients (13 males and 7 females) with ectopic ACTH syndrome caused by bronchopulmonary carcinoid confirmed by surgical pathology were selected from March 2007 to May 2016 in our hospital. We collected and arranged the important clinical data of 20 patients and analyzed carefully. Results The mean age of 20 patients including 14 patients of typical carcinoid and 6 patients of atypical carcinoid was 38.85±15.31 years ranged 13-70 years. All patients had the typical clinical manifestation of Cushing's syndrome. All the thoracic lesions were located by thoracic computed tomography (CT) eventually. The concentration of serum cortisol and ACTH significantly decreased after surgery. Postoperative complications in 3 patients (15.00%) were severe pulmonary infection. Eighteen patients including 13 patients of typical carcinoid and 5 patients of atypical carcinoid were followed up. The median time of follow-up was 31.5 (12-122) months. There were 7 patients of stage Ⅰa, 1 patient of stage Ⅰb, 2 patients of stage Ⅱa and 8 patients of stage Ⅲa in the patients followed up. One patient underwent postoperative radiotherapy, and 4 patients with postoperative chemotherapy. During the follow-up period, one patient relapsed and there was no death. Conclusion Ectopic ACTH syndrome caused by bronchopulmonary carcinoid is a very rare disease. It is every difficult for clinicians to make early diagnosis and draw up plans of treatment without multidisciplinary collaboration. Chest CT is an important method of finding lesions and assessing the viability of surgery. Surgical treatment in early stage will be effective for this disease. And almost all of patients can achieve long-term survival after complete resection of tumors early.
Objective To explore the evaluation value of burden of amplitudes and epileptiform discharges score (BASED) in the efficacy of adrenocorticotropic hormone (ACTH) combined with magnesium sulfate therapy for infantile epileptic spasms syndrome (IESS). Methods Retrospective collection the clinical and EEG data of 124 patients admitted to the Dongguan Maternal and Child Health Care Hospital from 2015 to 2023, who were diagnosed with IESS and treated with ACTH combined with magnesium sulfate. According to whether there were epileptic seizures 14 days after ACTH treatment, the patients were divided into two groups: non seizure group (n=74 cases) and seizure group (n=50 cases). The BASED system was used to evaluate the relationship between changes in EEG before and after ACTH treatment and clinical efficacy in both groups. The analysis of electroencephalogram included: ① abnormally high amplitude background waves, ② >3 spike foci , ③ grouped multifocal spikes, ④ paroxysmal voltage attenuation. ResultThe control rate of ACTH combined with magnesium sulfate in the treatment of IESS was 59.7% (74/124), and there was no statistically significant difference in the control rate among children with different etiologies (P=0.09). The BASED score suggests that the overall response rate of electroencephalogram (EEG) in infants with epileptic spasm syndrome after treatment was 57.2%. The EEG remission rate in the seizure control group was 81% (60/74), while in the uncontrolled group was 22% (11/50). The EEG remission rate in the seizure control group was significantly higher than that in the uncontrolled group after treatment (P<0.001), and the EEG score was closely related to clinical efficacy (Spearman correlation coefficient rp=0.601, P<0.001). ConclusionThe BASED score is related to clinical efficacy, and it can provide a quantitative basis for evaluating the efficacy of ACTH combined with magnesium sulfate in the treatment of IESS.
