Objective To set up a new method of mild hypothermia via lateral ventricle in rabbits following traumatic brain injury (TBI). Methods Twenty-one New Zealand rabbits were used for this study. TBI was pro- duced with all the rabbits in anesthesia by using free-falling impact model. Animals were randomly divided into three groups: a TBI group, a mild hypothermia group (by perfusion of 25℃Ringer's solution via the lateral ventricle) and a control group. The contents of water and total sodium, potassium of the brain region close to traumatic brain tissue were detected and pathological changes were observed in three groups. Results The number of the injured neurons was increased significantly in both TBI group and mild hypothermia group than that in control group at 72 h after TBI (P

Ocular surface disorders can be caused by the drug-derived toxicity,adverse effect and abuse of eye drops,and usually these disorders present with unspecific and untypical clinical findings.So the eye abnormality induced by topical administration of eye drops often is confused with some corneal inflammatory diseases.In addition,pathogenic mechanisms vary widely due to the different types of eye drops.Therefore,difficulty of diagnosis and poor curative effect often is a challenge for us.Ophthalmologist should be aware of the toxicity derived eye drops on ocular surface.Several noticeable problems of diagnosis and treatment of drug-derived keratopathy were elaborated in this paper.

Objective To explore the applicability of the abbreviated Chinese version of the social problem-solving inventory (C-SPSI) for nursing students in Shanghai. Methods The abbreviated C-SPSI was revised and 603 nursing students in Shanghai were surveyed by it, and the reliability and con-struct validity were evaluated by inter-item consistency analysis, test-retest reliability and principal factor analysis. Results The total CVI was 0.968. The construct validity was confirmed by factor analysis with 64.917% variance explained by four factors. The total Cronbach's α of C-SPSI was 0.897,and the total test-retest reliability coefficient was 0.781. Conclusions The abbreviated C-SPSI is an instrument with good reliability and validity and it can be used in assessing the nursing students' social problem-solving abilities and deficits.

Objective To evaluate the effect of insulin pumps in diabetic patients. Methods Perioporative 37 diabetic patients in our hospital were randomly divided into two groups;19 patients were given continuous insulin pump subcutaneously(CS Ⅱ), 18 multiple subcutaneous injection(MS Ⅱ), comparing the level of blood sugar control, pre-operative time, control of blood sugar levels, wound healing, and so on, postoperative enteral nutrition. Results Two groups of blood glucose levels before treatment had no significant difference (P > 0.5), after treatment the de-creased level of blood sugar and blood sugar level of stability in the CS Ⅱ group better than the MS Ⅱ group, the differ-ence was signifieant(P <0.01). CS Ⅱ significantly shortened the pre-operative preparation time,before and after op-eration and postoperative enteral nutrition ,control of blood sugar stable ,the wound healed well and shortened hospital stay. Conclusion Insulin pump is an effective manner in the perioperative treatment of diabetes for smoothing opera-tion, reducing the burden on patients and complications.

Objective:To investigate the effects of iron sucrose combined with recombinant human erythropoietin(EPO)on perioperative anemia and early functional recovery in elderly patients with intertrochanteric fractures.Methods:A retrospective comparative analysis was performed on 78 elderly patients who received PFNA treatment for intertrochanteric fractures in our hospital from July 2016 to December 2018.In the observation group, 40 cases were treated with iron sucrose combined with erythropoietin during the perioperative period.No perioperative intervention measures were taken for the control group.Hemoglobin(Hb)levels at 1, 3, 5, 7 days and before discharge and Harris scores of hip joints before surgery, 2 weeks and 3 months after surgery were compared between the two groups.Results:Hb levels were higher in the observation group than in the control group at 5 d[(98.8±8.6 g/L vs.92.2±8.5 g/L, t=3.389, P=0.001)]and 7 d[(105.4±8.9)g/L vs.(94.8±8.5)g/L, t=5.370, P=0.000]after surgery and before discharge[(115.4±8.6)g/L vs.(100.6±8.2)g/L, t=7.771, P=0.000]. Harris scores were higher in the observation group than in the control group 3 months after surgery(82.4±3.8 vs.75.8±2.5, t=8.933, P=0.000). Pearson' s correlation analysis showed that Hb levels at 5d and 7d after surgery were positively correlated with Harris scores at 3 months after surgery.Hb levels before discharge had an effect on Harris scores at 3 months after surgery. Conclusions:The combined administration of iron sucrose and EPO perioperatively can promote postoperative Hb recovery, reduce the incidence of anemia, accelerate early functional recovery and improve the quality of life in elderly patients with intertrochanteric fractures.

Objective To establish the model of P2 peptide-induced experimental autoimmune neuritis(EAN)in rats and explore the roles of Th_1/Th_2 type eytokines in EAN.Methods Lewis rats were grouped into EAN rats and control rats.The EAN rats were immunized by injection into both hind footpads of inoculums containing 100 ?g or 200 ?g of P2_(57-81)peptide and FCA while the control rats were immunized with FCA only.Clinical scores were compared at the maximum of disease.Supernatant productions of IFN- ?, IL-4 and IL-10 secreted by lymphocytes and obtained on day 14 after the immunization were examined. Histopathological assessment of sciatic nerves was made.Results Peak clinical scores of P2_(57-81)200 ?g (3.6?0.3)group were significantly higher than P2_(57-81)100 ?g group(2.2?0.6,P

The clinical, neuroelectrophysiological, neuropathological characteristics and outcome of a case of acute sensory axonopathy are reported. The patient was a 32-year-old female. She presented with acute onset sensory abnormalities, sensory ataxia, pseudoathetosis and areflex. Lab testing showed cerebrospinal fluid albumin cytologic dissociation. Electromyography studies and sural nerve pathology were consistent with acute sensory axonopathy. Treatment including intravenous immunoglobulin and steroid therapy was provided. Her symptoms recovered slowly without relapse, so did tibial H-reflex amplitudes.

Objectives To analyse the clinical and MRI features of cerebral autosomal dominant arteriopathy with subcortical infarct and leucoencephalopathy (CADASIL) in mainland China and compare these features with those reported in other countries.Methods All 26 CADASIL families were collected in First Hospital of Peking University from January 2003 to October 2009, and the diagnosis was confirmed by ultrastructural examination or Notch3 gene analysis.The age of onset, initial symptoms, main symptoms in 102 patients were described and the features with those reported in Germany, Japan, Arab and France were compared using x2 test.The cranial MRI changes in 35 patients were analysed and compared with the British and French patients.Results 102 patients had their initial symptoms between 22-80 years with the mean age of onset at (43.9 ± 11.0) years.There was no significant difference in the frequency of ischemic stroke or TIA (79.41% ) between our patients and the patients in other countries.Dementia rate (50.00% ) was significantly greater than that of Arab (21.05% ,x2 =5.513, P =0.020) and French patients(31.11%,x2 =4.517, P =0.034).The frequency of mood disturbances ( 14.71% ) was significantly lower than that of German patients (30.39% ,x2 =7.185, P =0.007).The frequency of migraine ( 13.73% ) was similar to that of France but lower than that of Japan (40%, x2 = 12.658, P = 0.000), Germany (38.24%, x2 =15.932, P=0.000) and Arab (42.11% ,x2 =6.869, P=0.009).Cranial MRIs were abnormal in all 35patients, but no lesion was seen in the medulla oblongata.Lacunar infarcts in the basal ganglia (82.86% )were significantly more frequent than that of French patients (60% , x2 = 5.663, P = 0.017).The frequency of leukoaraiosis in the cerebrum was similar to that of French patients.Anterior temporal involvement (68.57%) was significantly lower than of British patients ( 95%, x2 = 5.211, P = 0.022 ).Conclusion The clinical symptoms and MRI changes of CADASIL in different countries were not identical.Abnormal anterior temporal pole signal on MRI is not a sensitive marker for diagnosis of CADASIL in Chinese patients.
