Background As a new tonometer,it is necessary to assess the clinical value of Icare rebound tonometer.Objective This study was to compare the intraocular pressure(IOP)values measured by Icare with that measured by GAT,and discuss the clinical value of leare rebound tonometer. Methods IOP measurement was performed on 152 eyes of 78 subjects with suspicious glaucoma,glaucoma,refractive error and normal examinnee by Icare and GAT respectively.The Icare IOP was measured firstly and then the GAT IOP was carried out with the 3-or 5-minute interval.The IOP values were compared between Ieare and GAT.This study was approved by Ethic Committee of Wuhan General Hospital of Chinese PLA.Written informed consent was obtained from each subject prior to this study. Results The mean IOP values of Icare and GAT were(19.16±5.03)mmHg and(18.41±4.52)mmHg respectively.The differences between Icare IOP and CAT IOP were less than or equal to 1 mmHg in 96 of 105 eyes(63.2%).The positive correlation was found between the Icare IOP and GAT IOP(r=0.940,P<0.01).The Ieare IOP was lower than that of GAT when IOPIcare<16 mmHg,however,the IOP of Icare were higher when IOPIcare≥6 mmHg;the IOP of Icare were higher than that of GAT in the total CCT range.The correlation coefficients of IOP of Icare or CAT with CCT were 0.341(P<0.01)and 0.333(P<0.01),respectively. Conclusion Compared with GAT,Icare is more feasible in clinic because it is practicable and reliable.

Objective To evaluate the use safety of a unitary package peracetic acid ( PAA) disinfectant through acute and subacute toxicity experiments in rats.Methods This study was conducted according to the Technical Standard For disinfection ( Version 2002 ) .In the acute toxicity experiment, 60 healthy Wistar rats were randomly divided into different groups of PAA given by single intragastric gavage.Symptoms of poisoning of the animals were observed to calculate the half lethal dose ( LD50 ) .In the subacute toxicity experiment, 40 healthy Wistar rats were randomly divided into three dose groups and negative control group.The rats were given 33-342 mg/kg BW PAA for 28 days.At the end of test, the body weight, the organ-to-body weight ratio and the hematological and biochemical indices were determined, and pathological examination was performed.Results The acute oral LD50 of female rats was 1470 mg/kg BW, and the LD50 of male rats was 1710 mg/kg bw.The results of subacute toxicity test showed that the body weight, the organ-to-body weight ratio and the hematological and biochemical indices had no significant difference between the dose groups and control group.No obvious abnormality was observed in gross anatomy and histopathological examination.Conclusions The results of the acute toxicity test prove that PAA has a low toxicity level, and no significant subacute toxicity was observed at the exposure doses.

Objective To investigate the clinicopathologic characteristics,therapy and prognostic factors of small cell carcinoma of the cervix.Methods Clinical and pathological data of eight patients were analyzed retrospectively.Results Eight patients all presented with symptoms of abnormal vaginal bleeding or postcoital spotting.One patient had stage Ⅰ b1 disease,2 had stage Ⅰ b2 disease.2 had stage Ⅱ b disease and 3 had stage Ⅲ b disease.Histopathologic findings showed the small tumor cells had scant cytoplasm,round nuclei,absence of nucleoli,and finely dispersed chromatin.Immunohistochemical findings were positive in 7 cases for neuron-specific enolase.Three patients with stage Ⅰ b disease and 1patient with stage Ⅲb disease underwent radical hysterectomy and postoperative chemotherapy.with or without radiotherapy,and the survival period was 64,22,14 and 6 months respectively.Two patients with stage Ⅱ b disease and 2 with stage Ⅲ b disease underwent chemotherapy and radiotherapy,and the survival period was 25,9,10 and 5 months respectively.Conclusions Immunohistochemical analysis using several kinds of neuroendocrine markers is helpful in establishing the correct diagnosis in addition to focusing on characteristic histopathological features.It is necessary to use comprehensive treatment including surgery,chemotherapy and radiotherapy for patients with small cell carcinoma of the cervix.Chemotherapy may play an important role in the treatment.

Objective:To investigate the effect of miR-150 gene deletion on the breeding and hematologic parameters of mice. Methods:The nest litter size,wean rate and weight changes of miR-150 knock out (miR-150ko) and C57BL/6J mice were com-pared. The hematology indexes were analyzed by automated blood cell counter, the serum biochemical parameters were analyzed by automatic biochemical analyzer. Results:The nest litter size and wean rate of miR-150ko mice were significantly decreased compared with that of C57BL/6J mice. The number of total white blood cells,intermediate cells,neutrophils,and the percentage of neutrophils and intermediate cells were significantly increased in miR-150ko mice compared with that of C57BL/6J mice. However,the number and per-centage of platelets and lymphocytes decreased significantly in miR-150ko mice. In addition,the levels of serum glucose and TC were in-creased significantly in miR-150ko mice compared with that of C57BL/6J mice. Conclusion: miR-150 gene deletion impairs the breeding and has complex impact on hematologic parameters of mice.
