The experimental study of cerebral ischemia plays an important role for understanding the pathogenesis of ischemic brain injury, but its correlation with the clinical therapeutic strategies has certain limitations. One of its main reasons is that the experimental models and methods can not or only partially repeat the pathophysiological processes of natural cerebral ischemia. In order to promote the understanding and interpretation of the experimental data, we review the commonly used experimental animal models and modeling methods and mainly elaborate the methods of current different in vivo and in vitro clinical evaluation. Based on these studies, we believe that the standardized clinical evaluations are hugely important for assessing the experimental results and clinical transformation.

BACKGROUND: With development of modern medical sciences, the out comes after meningioma surgery cannot be fully assessed using morbidity,livability and mortality merely. Quality of life (QOL) is a health-related multivariable index, which provides integrated inf ormation associated with physiological,sychological and social adaptation status of the patients to doctors. Assessment of the QOL in meningioma patients may be one of a relatively good method for guiding surgery and reducing reoccurrence of tuOBJECTIVE: To evaluate the QOL in meningioma patients and then to provide relevant data for assessing the outcomes of meningioma surgery comprehensively.DESIGN: It was a single-sample investigation. SETTING: Neurosurgery Department, Second People's Hospital of Wuxi City of Nanjing Medical University.PARTICIPANTS: Totally 147 patients underwent meningioma surgery in the Neurosurgery Department of the Second Affiliated Hospital of Wuxi City affiliated to Nanjing Medical University between January 1995 to January 2001 were selected, 61 males and 86 females, with a male/female ratio of 2:3 and an age ranging from 5-77 years old, in average of 43 years old, and the median was 43 years old.METHODS: Based on World Health Organization Quality of Life 100item questionnaire (WHOQOL-100) and Karnofsky Performance Scale (KPS), we designed a questionnaire on QOL in patients with meningioma.Outcomes of the transverse investigation on 147 meningioma patients were compared with healthy controls. Surgery-related QOL curve was used for identifying the threshold satisfactory point of QOL. In addition, with selfcontrol, influence of surgery on QOL was assessed.MAIN OUTCOME MEASURES: Relationship between QOL and clinical histories, radiological analysis, operation grading, histological properties and reoccurrence were investigated.RESULTS: All of the 147 patients entered the statistical analysis. ①In patient with meningioma, Cronbach's coefficient was 0.9521 and the correlated coefficient was 0.8685, which suggested that QOL questionnaire for patients with meningioma had a good reliability and validity. ②QOL ≥70 represented that the patient was satisfied with the QOL. ③In patients underwent surgical treatment, their physiological functions, self-help and self-care except for psychological functions were significantly improved (P ＜ 0.001 ).CONCLUSION: Surgical treatment enables patients to get a satisfied QOL. QOL questionnaire for patients with meningioma is helpful to provide relevant data for meningioma operation.

Objective To investigate the clinical characteristics, operation time and methods for patients with central brain herniation caused by bifrontal contusions. Methods A retrospective study was performed on the medical records of patients with central brain herniation caused by bifrontal contusions admitted from January 2000 to December 2006. There were 45 males and 18 females, at age range of 20-72 years (average 43 years). The majority of the patients were victims of falls and traffic accidents. There were 29 patients treated with immediate operation and 34 with emergency operation. All the operations involved simultaneous bilateral craniectomy for decompression, including 17 patients treated with bilateral decompressive craniectomy and 46 with unilateral decompressive craniectomy. Results The prognosis was favorable in 19 patients with GOS score of 5 or 4 points, severely disabled in seven with GOS score of 3 points, vegetative in four with GOS score of 4 points and the worst in seven with GOS score of 1 point. Of all, 19 patients suffered severe mental disorders especially personality change and disturbance of intelligence. Seven patients were complicated by epilepsy and three by hydrocephalus. Conclusions Based on early clinical manifestations of central brain herniation combined with imaging manifestations, bilateral balance decompression craniectomy can reduce the mortality and morbidity and improve the cure rate of patients with central herniation caused by bifrontal brain contusions.

Objective To establish and validate an ultra performance liquid chromatography-tandem mass spectrometric (UPLC-MS/MS)method for quantification of MRX-I,a new oxazolidinone antibacterial agent,in human plasma and urine.Methods Chromatographic separation was performed on a Waters ACQUITY UPLC BEH C8 column using an isocratic elution.The mo-bile phase consisted of acetonitrile and water (40∶60,v/v).Quantitative analysis was conducted in the multiple reaction moni-toring mode.Linezolid was used as an internal standard.Liquid-liquid extraction with ethyl acetate was used to remove impuri-ties in the plasma and urine samples.The method was validated in terms of matrix effect,recovery,precision,accuracy and stability.Results The calibration curves were linear within the range of 0.005 00-1 .00 mg/L.The lower limit of quantification was 0.005 00 mg/L for both plasma and urine samples.Retention time was less than 1 .5 min for both MRX-I and internal standard in plasma and urine.The ma-trix effect factors of plasma and urine for MRX-I was 90.4%±8.2% and 82.7%±7.9%,respectively.The recovery of MRX-I was 112.8% ± 13.4% from plasma and 105.6% ± 13.4% from urine samples,respectively.The inter- and intra-day accuracy of MRX-I was 98.9%-105.0% and 96.5%-102.6% in plasma samples,and 92.7%-98.6% and 95.1 %-105.7% in urine samples.MRX-I was stable for 24 h at room tem-perature,48 h in automatic sampler after pretreatment,and stable after 3 freeze-thaw cycles in plasma and urine.MRX-I was also stable at-40℃for eight months in plasma and six months in urine,respectively.Conclusions The UPLC-MS/MS method established in this study shows high sensitivity and specificity for determination of MRX-I in human plasma and urine.The re-sults of validation are consistent with the requirement of bioanalytical method validation.

Objective To investigate the neuroprotective effect of sophocarpine against transient focal cerebral ischemia via down-regulation of the acid-sensing ion channel 1(ASICl) in rats.Methods Twenty-five SD rats were randomly allocated into sham operation,cerebral ischemia/reperfusion,and 5,10,and 20 mg/kg sophocarpine pretreatment groups (n=5 in each group).A rat focal ischemia model was induced by the intraluminal suture method.Five,10 and 20 mg/kg sophocarpine were injected intraperitoneally for pretreatrnent.2,3,5-triphenyltetrazolium chloride staining was used to detect cerebral infarct volume.TUNEL staining was used to detect apoptosis.Immunohistochemistry and Western blot were used to detect the expression of ASIC1 and ASIC2.Results The infarct volume after ischemia-reperfusion was(181.21±9.21)mm3,while the 5,10,and 20 mg/kg sophocarpine pretreatment groups were(150.12±6.19),(52.31±4.20),and(32.18±3.82)mm3,respectively;the neurological function scores in the cerebral ischemia/reperfusion group was(3.62±0.36),while the 5,10,and 20 mg/kg sophocarpine pretreatment grows were(3.15±0.36),(1.92±0.18),and(1.85±0.21),respectively;The surviving neurons only accounted for(31.2±2.8)% of the total cell number in the cerebral ischemia-reperfusion group,while they accounted for(51.2±3.7)%,(76.5±2.1)%,and(77.1±4.1)% in the 5,10,and 20 mg/kg sophocarpine pretreatnmat groups.Compared with the cerebral ischemia/reperfusion group,the cerebral infarct volume was decreased significantly in the sophocarpine pretreatrnent groups(all P<0.01),the neurological function scores were decreased significantly(all P<0.01),and the number of apoptotic cells was decreased significantly (all P<0.01).Immunohistochemistry showed that the number of ASIC-1 positive cells in the sham operation,cerebral ischemia-reperfusion,and 5,10,and 20 mg/kg sophocarpine pretreatment groups were(162.5±8.3),(165.1±5.3),(138.3±7.2),(82.1±6.3),and(69.2±5.5)/mm respectively;Western blot showed that the ASIC1 protein expression was decreased sigaificantly in the 10 and 20 mg/ky sophocarpine pretreatment groups (P<0.01),while there WaS no significant difference in the ASIC2 protein expression.Condusions Sophocarpine may play a neuroprotective role for cerebral ischemia-reperfusion injury in rats via down-regulating the expression of ASIC1 protein.

Background and purpose:Myelosuppression is the most common dose-limiting toxicity of tumor chemotherapy in which leukocytopenia and neutropenia are the most common conditions. Not only are up-titrations of the doses of chemotherapeutic drugs limited, but also normal process of the chemotherapy is affected. Filgrastim-Recombinant Human Granulocyte Colony-Stimulating Factor (rhG-CSF) has the activity of stimulating the formation of granulocyte colony and promoting the growth, proliferation and differentiation of granulocytes which can be signiifcantly effective on leukocytopenia and neutropenia induced by chemotherapy. In this study, we observed the leukogenic effects, toxic and side effects of low, medium, and high doses of rhG-CSF used prophylactically after chemotherapy in patients with advanced non-small cell lung cancer (NSCLC), to explore a rational application strategy for rhG-CSF..Methods:One hundred and twenty six patients with pathologically proved advanced non-small cell lung cancer (NSCLC) under chemotherapy were digitally randomized to A, B and C groups. Filgrastim was given to patients of the three groups 24h after the end of chemotherapy. The dosages are: Group A (low dose): 300 μg of Filgrastim, s.c., qd × 1 day; Group B (medium dose): 300 μg of Filgrastim, s.c., qd × 2 days; Group C (high dose): 300 μg of Filgrastim, s.c., qd × 3 days. Then the signs and symptoms as well as toxic and side effects of Filgrastim after medication were observed.Results:Prophylactic usage of medium and high dosages of rhG-CSF could maintain WBC count at no less than 4.0×109/L in nearly 60% of patients. In patients with Grade III leukopenia, more days were needed for recovery of white blood cell (WBC) count with the low dose, while signiifcantly (P<0.05) less days were needed with the high dose. In view of the dynamic changes of neutrophil(ANC), additioning of the high dose of rhG-CSF after chemotherapy could increase the average level ofANC, notably shortening the duration of lowANC caused by chemotherapy. The incidence of infections was 4.76% for the 126 patients as a whole, 9.52% for the low dose group, and 4.76% for the middle dose group. The patients could tolerate the slight side effects incurred during treatment with Filgrastim.Conclusion:All of the three doses (low, medium, and high) of prophylactic administration of Filgrastim after chemotherapy can promote recoveries of WBCs and neutrophil granulocytes and reduce opportunities of infections. High doses of rhG-CSF can be faster and safer in increasing WBCs and neutrophil granulocytes.

Objective To measure the concentration of serum transthyretin (TTR) of patients with different stages of diabetic retinopathy (DR).Methods A total of 176 patients with diabetes mellitus were included in this study.There were 104 males and 72 females.The patients aged from 21 to 74 years,with the mean age of(56± 11) years.The diabetes duration raged from 1 to 30 years,with the mean diabetes duration of (10 ± 7) years.The HbA 1C was 5.2％-14.1％,with the mean HbA 1C of (8.6 ± 2.0)％.According to the fundus examination,58 patients had DR (33.0％),but the other 118 patients not (67.0％).For these DR patients,10 patients were in stage Ⅰ (5.7％),26 patients in stage Ⅱ (14.8％),8 patients in stage Ⅲ (4.5％),and 14 patients in stage Ⅳ (8.0％).The concentration of serum TTR was measured by enzyme-linked immunosorbentassay kit.The differences in the concentration of serum TTR between different DR stages were compared.Bivariate analysis was used to analyze the influencing factors of TTR.Results The concentrations of serum TTR of the patients without DR or with DR of stage Ⅰ to Ⅳ were (224.96±65.47),(383.68± 102.99),(247.44±63.21),(228.2 ± 45.89),(189.34± 70.12) mg/L,respectively.The difference between different DR stages was statistically significant (F=14.690,P＜ 0.001).Bivariate analysis showed that the concentration of TTR was correlation to DR (r=0.179,P=0.017).There was no correlation between the concentration of TTR and diabetes duration (r=-0.027,P=0.727),hypertension (r=0.018,P=0.810),hyperlipoidemia (r=0.101,P=0.182),and the use of insulin (r=-0.032,P=0.675).Conclusion The concentration of serum TTR was increased in early DR patients,and gradually decreased with the progression of DR.The concentration of TTR is correlated to DR.

Objective To explore the limits of fluid-inversion prepared diffusion weighted imaging (FLIPD) in detection of acute cerebral ischemic lesions.Methods From January 2012 to March 2014,forty-nine patients (33 males,16 females,age (55.6± 12.3) years) clinically diagnosed as transient ischemic attack (TIA) were included.Patients underwent brain MRI (conventional diffusion weighted imaging (DWI) and FLIPD) within 3 d after the onset of TIA.The detection ability of MRI with the two sequences was compared,and the relative signal intensity (rSI) and apparent diffusion coefficient (ADC) of acute ischemic lesions based on two sequences were compared.Kappa test and two-sample t test were used to analyze the data.Results A total of 87 acute ischemic lesions were detected in 21 patients by conventional DWI,and 54 were detected in 19 patients by FLIPD (Kappa=0.916,P＜0.05).The rSI of ischemic lesions on FLIPD was significantly lower than that on conventional DWI (1.37±0.22 vs 1.57±0.26;t=6.647,P＜0.001).The ADC value of ischemic lesions on FLIPD was slightly lower than that on conventional DWI:(0.54 ±0.10) ×10-3 mm2/s vs (0.57±0.13)×10-3 mm2/s (t=2.120,P＜0.05).The missed lesions on FLIPD were located in the white matter (n =18),cerebellum and brainstem (n =8),and the cortex (n =7).Conclusions A slight diffuse abnormality may be missed on FLIPD,so this method is not suitable for the detection of acute ischemic lesions.FLIPD technology still needs improvement.

Objective To investigate the use of parenteral nutrition preparations in Jiangsu Province,and to provide reference for the standardized management of parenteral nutrition preparations.Methods 720 cases using parenteral nutrition preparations from January 2017 to June 2017 in the department of general surgery of 12 hospitals in Jiangsu province were selected.The rate of nutritional risk screening,the indications of parenteral nutrition,the way of infusion,the rationality and economy of the prescriptions were retrospectively evaluated.The calorie,amino acid content,non-protein calorie/nitrogen ratio,glycolipid ratio and cation concentration of the patients received total parenteral nutrition were calculated.Results The total costs of parenteral nutrition preparations of 720 cases were 1.614 1 millions,and 346 cases did not have the indications for parenteral nutrition.The results of prescription comment showed that only 16 patients were screened for nutritional risk by Nutritional Risk Screening 2002 tool at admission.544 cases were intravenous dripped with amino acid and fat emulsion from peripheral vein.In the 176 total parenteral nutrition prescriptions,there were 39 non-protein calorie/nitrogen ratio cases,15 glycolipid ratio cases,69 cation concentration cases,61 calorie cases and 32 amino acid content cases failing to comply with the recommendation of the guidelines.Only 31 total parenteral nutrition prescriptions were completely reasonable.Conclusion The costs of parenteral nutrition preparations used in hospitals of Jiangsu are high but the rate of rationality is low.Nutrition support team should be established to regulate the use of parenteral nutrition preparations and save medical resources.
