Objective To investigate the therapeutic role of hyperbaric oxygen(HBO) on neonatal hearing impairment induced by hypoxic-ischemic encephalopathy(HIE),by observing the brain stem auditory evoked potential(BAEP) changes of newborn infants with HIE.Methods One hundred and six cases of HIE in newborn infants(in which 82 cases were mild and 24 cases were severe) treated with HBO and conventional therapy were chosen as HBO treatment group,while other 42 cases of HIE in newborn infants(in which 38 cases were mild and 4 cases were severe) treated with conventional therapy only were served as control group.BAEP was measured at the 3rd to 7th day on patients before treatment and 42 days after birth with or without HBO therapy respectively,and the differences of BAEP changes were compared between the both groups.Results 1.In control group,the rate of abnormality was 47.4% and 31.6%,respectively before and after therapy in mild HIE cases(P=0.240),and 75.0%,50.0% in the moderate-severe HIE cases(P=0.462).2.In HBO group,the abnormal rate was 45.1% and 25.6%,respectively in mild HIE cases before and after therapy,while 75.0% and 41.7% in moderate-severe HIE cases(Pa=0.014,0.039).3.There was obvious difference between control group and HBO group in mild HIE cases(P=0.013),while there was no significant change between the 2 groups in moderate-severe HIE cases(P=0.717).Conclusions Treatment with HBO combined with conventional therapy may improve the abnormal rate of BAEP in patients with HIE according to the present test,especially in mild HIE cases,thus earlier HBO therapy may be used to mitigate hearing impairment and improve prognosis induced by the disease.

Objective To investigate the morphology and quantity of melanin and blood vessels in chloasma lesions by using reflectance confocal microscopy(RCM)and dermoscopy, and to explore the relationship of melanin and blood vessels with lesion color. Methods RCM was used to evaluate the quantity and distribution of melanin in lesions of 135 patients with chloasma, and to observe the morphology of melanin and dendritic melanocytes in 54 of the 135 patients, and dermoscopy was performed to assess the quantity and morphology of blood vessels in lesions of the 54 patients. Statistical analysis was carried out by Spearman correlation analysis to assess the relationship of melanin and blood vessels with lesion color. Results Increased quantity of melanin was observed in both the epidermal layer and dermo?epidermal junction in all the 135 patients, and in only the superficial dermis in 36(27%)patients. No patients showed increased quantity of melanin in only the dermis without epidermal involvement. Among the 54 patients, there was a positive correlation between the quantity score and morphology score of melanin(r=0.73, P<0.001), between the quantity score and morphology score of blood vessels(r=0.87, P<0.001), as well as between the total melanin score and total blood vessel score(r=0.554, P<0.001). Lesion color was positively correlated with the quantity and morphology of melanin(r = 0.51, 0.39, respectively, both P < 0.05)and blood vessels(r = 0.46, 0.44, respectively, both P<0.05). Conclusions RCM and dermoscopy can be used to evaluate melanin and blood vessels in chloasma lesions. There is a positive correlation between the quantity and morphology of melanin and between those of blood vessels in chloasma lesions, and lesion color is positively correlated with the quantity and morphology of melanin and blood vessels.

Objective:To investigate the effects of the psychological stress on peripheral blood lymphocytes apoptosis and Bax,Bcl-2 gene expression in rats after being given different intensity of noise stress.Methods:All 24 SD rats were divided into three groups:control,high intensity of the noise stress,middle intensity of the noise stress. The apoptosis in peripheral blood lymphocytes(PBL)of rats was demonstrated with the flow cytometer to determine the percentages of apoptosis in rat PBL,and the expression changes of related Bcl-2,Bax genes were observed by us- ing immunohistochemical method.Results:1)After high intensity of the noise stress for three weeks,the apoptosis in rat PBL increased significantly compared with the control.2)After high intensity of the noise stress for three weeks, Bcl-2 expression as down-regulation in PBL,but the B ax expression remained obviously high.Conclusion:It indi- cates that apoptosis exists in the immunocytes of rats in the course of high intensity of the psychological stress and it consists with the expression of the related regulatory genes.

Objective To investigate the accuracy of liver volume measurement in patients with primary hepatocellular carcinoma by using the 3D + medical imaging visualization processing system. Methods Thirty patients who were clinically diagnosed as primary hepatocellular carcinoma and underwent surgical resection before preoperative assessment were selected from January 2016 to November 2016. Preoperative thin-slice CT images were transferred into the 3D + medical imaging visualization processing system for hepatic volume measurement, the predictive resection volume were measured and statistically analyzed with that of intraoperative specimen according to water measurement method. Results All patients had complete resection of tumor, the average volume of predictive resection calculated by the 3D software was (408.84 ± 177.07) ml, the average volume of intraoperative specimen measured by the water test was (399.95 ± 176.15) ml, the difference was not statistically significant (t=1.502, P=0.144), and the average percentage error was (6.21 ± 4.73) %. Pearson correlation analysis showed that there was significant correlation between them (r=0.983, P<0.05). Conclusion 3D+medical image visualization processing system is a simple, intuitive and accurate method for liver volume measurement, which can provide the basis for the accurate measurement of liver volume and the implementation of complex hepatectomy, and guide the precise hepatectomy.

● AIM: To investigate the sequential changes of HIF-1 α Protein and mRNA in hypoxic bovine retinal microvessel endothelial cells.● METHODS: The bovine retinal microvessel endothelial cells were cultured in normoxic and CoCl2-induced hypoxic conditions respectively. Expressions of HIF-1 α Protein were measured with immunohistochemical staining, and RT-PCR was used to determine the HIF-1 α mRNA.● RESULTS: HIF-1 α began to increase 1h after hypoxia,and reached the peak at 4h. After 16h, it declined significantly. Compared with the normoxic group, the expression of HIF-1 α protein in the hypoxic groups had significant difference (P＜0.01), and HIF-1 α mRNA expression was unchanged under hypoxia.● CONCLUSION: HIF-1 α participates in the hypoxic procedures in retinal microvessel endothelial cells, and hypoxia induce time-dependent changes of HIF-1 α protein expression, which is not modulated on the transcription level. Analysis of HIF-1 α expression revealed a temporal and spatial changes with regard to the hyperoxic repression, indicating that HIF-1 may play a major role in the development of retinopathy of prematurity and other ischemic retinal disorders such as diabetic retinopathy.
