Objective To investigate the clinical value of amplitude integrated electroencephalogram on early diagnosis and prognosis evaluation of brain injury caused by neonatal asphyxia.Methods A total of 34 full-term asphyxiated neonates(asphyxia group)hospitalized in NICU of our hospital from January 2015 to September 2015 were selected;meanwhile,34 full-term healthy infants(control group)of the same term were selected.All cases were monitored for the activities of aEEG background,sleep-awakening cycle(SWC)and epileptic activity(SA)within 6 hours after birth.Meanwhile,the relationships between various indexes and asphyxia degree and brain injury were analyzed.Results The electroencephalogram of the asphyxia group was 52.9％and the rate of SWC was 58.8％,which were lower than those of the control group,and the difference had statistic significance(P<0.05).Meanwhile,neonates with epileptic activity in asphyxia group accounted for 11.8％,which was higher than that of control group significantly(P<0.05).Conclusion The AEEG changes of neonates at early period after birth are closely related to perinatal asphyxia and brain injury after asphyxia.The application of amplitude integrated electroencephalogram has an important significance on early diagnosis of neonatal asphyxia.

The incidence of hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is very high,and the prognosis is often unsatisfactory.Currently,some therapy such as radiotherapy or radiation combined with interventional therapy are effective and worth attention.Radiation therapy was divided into external beam radiation therapy and internal beam radiation therapy according to different administration pathway.This article summarized the current situation and prospect of radiotherapy.

AIM: To analyze the clinical feature and treatment of endogenous endophthalmitis caused by liver abscess. METHODS: A total of 9 eyes (7 cases) with endogenous endophthalmitis caused by liver abscess in our hospital from 2005 to 2010 were analyzed retrospectively. Microorganism was cultivated with blood or vitreous in all patients.4 eyes were performed vitrectomy. 2 eyes were injected antibiotics in vitreous cavity. 3 eyes were only treated with antibiotics.RESULTS: Two cases (2 eyes) were diagnosed with endophthalmitis firstly, then found liver abscess; 4 eyes were with diabetes mellitus, and 1 eye with abnormal glucose tolerance. Cultivation of microorganism was positive in 6 eyes (67%), including Pneumonia cray-research, Candida albicans and Escherichia coli. 5 eyes had useful vision after treatment, 1 eye had light perception,3 eyes became blindness. CONCLUSION: As an ocular emergency, endogenous endophthalmitis caused by liver abscess can severely damage visual function. Timely consultation, early diagnosis, proper systemic and topical anti-infective and anti-inflammatory treatment are the most effective methods for controlling infection. Vitrectomy with intravitreal antibiotics plays an important role in preserving useful vision function in patients.

Objective To explore the difference in the incidence of deep vein thrombosis (DVT) following total knee arthroplasty (TKA) or total hip arthroplasty (THA) between different seasons.Methods The present retrospective study examined 2 363 patients undergoing TKA or THA from August 2008 to February 2016.There were 653 male and 1 710 female with the average age of 64.44±13.03 years old (17-91 years old),including 954 patients in TKA and 1 409 in THA.All of the patients received anticoagulant drugs and were compressed with a pressure pump starting on the first postoperative night.Routine venography of the bilateral lower limbs was performed at 3-5 days after the operation.The incidence of DVT in different seasons and different age groups (≥65 years old and ＜65 years old) were counted.Results The present study suggested that the probabilities of DVT after arthroplasty in spring,summer,fall and winter were 15.85％ (116/732),14.92％ (71/476),17.88％ (108/604),22.50％ (124/551) respectively with significantly difference (P＜0.05).The incidence of DVT in winter was higher than that in spring and summer (P＜ 0.017).The probabilities of DVT after TKA in spring,summer,fall and winter were 19.09％ (59/309),15.67％ (37/236),18.11％ (44/243),27.71％ (46/166) respectively with significantly difference (P＜0.05).The incidence of DVT in winter was higher than that in summer (P＜0.017).The probabilities of DVT after THA in spring,summer,fall and winter were 13.48％ (57/423),14.17％ (34/240),17.73％ (64/361),20.26％ (78/385) respectively with significantly difference (P＜0.05),and that in winter was higher than in spring (P＜0.017).The symptomatic DVT after arthroplasty in spring,summer,fall and winter were 3.55％ (26/732),3.78％ (18/476),4.97％ (30/604),6.90％ (38/551) with significantly difference in different seasons (P＜0.05),and that in winter was higher than in spring (P＜0.017).The symptomatic DVT after TKA in spring,summer,fall and winter were 3.88％ (12/309),4.24％ (10/236),4.94％ (12/243),9.64％ (16/166) with significantly difference in different seasons (P＜0.05).The symptomatic DVT in winter was higher than that in spring (P＜0.017).The symptomatic DVT after THA in spring,summer,fall and winter were 3.31％ (14/423),3.33％ (8/240),4.99％ (18/361),5.71％ (22/385) respectively (P＞0.05).The probability of DVT following arthroplasty in older patients (age≥65 years old) in spring,summer,fall and winter were 18.49％ (76/411),16.61％ (45/271),22.07％ (81/367),28.05％ (99/353) with significantly difference among the groups (P＜0.05),while symptomatic DVT in older patients (≥65 years old) in spring,summer,fall and winter were 4.38％ (18/411),4.43％ (12/271),5.72％ (21/367),8.78％ (31/353) respectively with significantly difference (P＜0.05).The probability of DVT in four seasons were 12.46％ (40/321),12.68％ (26/205),11.39％ (27/237),12.63％ (25/198) in younger patients (＜65 years old).However,the difference was not detected among different seasons (P＞0.05).The probability of symptomatic DVT in four seasons were 2.49％ (8/321),2.93％ (6/205),3.80％ (9/237),3.54％ (7/198) in younger patients (＜65 years old) without significant difference (P＞0.05).Conclusion Seasonal variations could place an important effect on the incidence of DVT following TKA or THA,especially for the old patients with age ≥65 years.

OBJECTIVETo explore the inhibition and molecular mechanism of icaritin (ICT) combined doxorubicin (DOX) on human osteosarcoma MG-63 cells in vitro.

METHODSThe control group, ICT groups (10, 20, 40, 80, and 160 µmol/L), DOX groups (1, 2, 4, 8, and 16 µg/mL), and combination groups (20 µmol/ L ICT +1 µg/mL DOX, 20 µmol/L ICT +2 µg/mL DOX, 20 µmol/L ICT +4 µg/mL DOX, 40 µmol/L ICT +1 µg/mL DOX, 40 µmol/L ICT +2 µg/mL DOX, 40 µmol/L ICT +4 µg/mL DOX, 80 µmol/L ICT +1 µg/mL DOX, 80 µmol/L ICT +2 µg/mL DOX, 80 µmol/L ICT +4 µg/mL DOX) were set up. Human osteosarcoma MG-63 cells were respectively cultured and their effects on morphological changes were observed using inverted phase contrast microscope after 24-and 48-h intervention. The cell proliferation inhibition rate of each group was de- termined using CCK-8, and IC50 calculated. The MG-63 apoptosis rate was detected using Annexin V-FITC/ PI double dye flow cytometry. Expression levels of bcl-2, caspase-3, and p21 were detected using RT-PCR.

RESULTSICT and DOX could obviously inhibit the proliferation of MG-63 cell. Along with ICT concentration increasing from 10 µmol/L to 160 µmol/L, the cell proliferation inhibition rate also increased gradually from 9.67% ± 3.62% to 89.18% ± 9.66%. The IC50 was 46.93 µmol/L and 3.87 µg/mL respectively. ICT and DOX could cause either early or late stage apoptosis, down-regulate Bcl-2 gene expression, and up-regulate gene expressions of Caspase-3 and p21 respectively (P < 0.05). Aforesaid changes were more obviously seen in combination groups than in lCT groups and DOX groups (P < 0.05).

CONCLUSIONCT combined DOX had additive or synergistic inhibition effect for the proliferation of osteosarcoma MG-63 cells, which might be related with regulating gene expressions of bcl-2, caspase-3, and p21.

Objective To investigate the role of circulating neutrophil extracellular trap (NET) levels in the postoperative formation of deep vein thrombosis (DVT) in patients undergoing total knee arthroplasty (TKA). Methods Circulating NET levels were measured preoperatively and on postoperative days 1, 3, and 7 in 30 patients diagnosed with DVT by venography after TKA and 30 controls from May 2014 to July 2015. Results In patients with DVT, the mean circulating NET levels were significantly higher on postoperative days 1 and 3 compared with those in the non?DVT group (postoperative day 1, 1.598 ± 0.067 vs. 1.212 ± 0.037, t=7.514, P=0.000;postoperative day 3, 1.305±0.044 vs. 1.167±0.032, t=2.675, P=0.015). ROC curve analysis revealed the inferior sensitivity and specificity of NET levels on postoperative day 3 compared with postoperative day 1. Area under the curve (AUC) postoperative day 1 was 0.828 (95%CI:0.722, 0.933, P=0.000);AUC postoperative day 3 was 0.677 (95%CI:0.541, 0.814, P=0.018). The cutoff point for NET levels on postoperative day 1 was 1.294, with a sensitivity of 80%, a specificity of 80%, a posi?tive predictive value of 80%, and a negative predictive value of 80%. After Logistic regression, the NET level on postoperative day 1 was considered an independent predictor of DVT (OR:24.08, 95%CI:4.94, 117.28, P=0.000). Conclusion High circulating NET levels are associated with DVT in patients who undergo TKA. NETs may serve as a potential biological marker to delineate patients undergoing TKA who are most at risk for DVT.
