Objective To explore the relationship between the test of drug-induced electroencephalography(EEG) and epilepsy.Methods324 patients with epilepsy were randomly divided into 2 groups, the benadrly group(n=162) and chloral hydrate group(n=162) as control. EEG was examined by evoking during sleep to observe epileptiform discharge and which stage of non-rapid eye movements (NREM) epileptiform discharge occurred more frequently.ResultsThe epileptiform discharge was 31.61% in benadrly group, and 18.52% in chloral hydrate group. There was significant difference between the two groups (P<0.01). The detection rate of epileptiform discharge at the stage I~II of NREM was significantly higher in benadrly group (83.7%) than in chloral hydrate group(63.3%)(P<0.05), which suggested that epileptiform discharge frequently occurred at the stage I~II of NREM.ConclusionBenadrly is superior to chloral hydrate in the test of drug-induced EEG of epilepsy.

Objective:
To study the effects of Lycium barbarum polysaccharides ( LBP ) on blood indexes and liver tissue morphology in rats with intrahepatic cholestasis.
Methods:
Sprague-Dawley rats were randomly divided into the control group, the model group, and LBP low, medium and high dose group. The rats in the model group and LBP dose groups were given 60 mg/kg alpha-naphthylisothiocyanate ( ANIT ) by gavage every three days of the experiment, and the rats in the control group were given salad oil instead of ANIT. From the third day, the rats in each dose group were given 40, 150 and 600 mg/kg LBP, and the rats in the model group were given distilled water. After four weeks, the blood and urine indexes were measured, and the morphological changes of liver tissue were observed.
Results:
From the third day of the experiment, the activity of rats in the model group and LBP dose groups decreased, and the color of urine changed to dark yellow. There was no abnormality in the group. In the model group, the levels of serum total bilirubin, direct bilirubin, total bile acid ( TBA ), alkaline phosphatase ( ALP ), γ-glutamyltransferase(γ-GGT), cholesterol, alanine aminotransferase ( ALT ), aspartate aminotransferase ( AST ), white blood cell ( WBC ), percentage of granulocyte, urinary bilirubin, urinary bile acid, liver mass and liver to body ratio were higher than those in the control group, while red blood cell and percentage of lymphocyte were lower than those in the control group ( all P<0.05 ). Pathological changes of liver tissue were observed. The levels of serum TBA, ALP, γ-GGT, ALT, AST, WBC and liver to body ratio in LBP high dose group were lower than those in the model group ( all P<0.05 ). The infiltration of inflammatory cells, proliferation and expansion of bile duct, degeneration and necrosis of liver cells were alleviated.
Conclusions
LBP can improve the blood indexes and pathological changes of liver tissue in rats with intrahepatic cholestasis at the dosage of 600 mg/kg. Inhibition of inflammatory response and reduction of oxidative stress injury may be the mechanism for alleviating cholestatic liver injury.

Objective:
To evaluate the safety of a herbal pilatory for external use.
Methods :
An acute eye irritation test were employed to detect the eye irritation of the herbal pilatory;a skin irritation test,a skin sensitization test and a skin phototoxicity test were employed to detect the dermal toxicity;Salmonella typhimurium reverse mutation assay(Ames test)and chromosome aberration test in CHL cells were employed to detect the effects of the pilatory on gene mutation and chromosome aberration in prokaryotic and eukaryotic cells.
Results:
When the eyes of rabbits exposed to the pilatory without rinse during the first 24 hours,the conjunctiva showed congestion and edema with the highest score of 2,corneal opacity was observed with the highest score of 1;however,these symptoms returned to normal within 72 hours,with the score reduced to 0. No irritation to the skin of rabits was found after exposed to the pilatory for fourteen days,no skin sensitization was introduced by Buehler test and no skin phototoxicity on guinea pigs was detected. There was no abnormal growth of reverse mutation colonies induced by the pilatory under S9 acitivation or not. There was no statistically significant rise of chromosome aberration rate in the exposed CHL cells compared to the control groups(P>0.05).
Conclusion
Under the condition,the herbal pilatory showed mild and reversible irritation to eyes,while no dermal toxicity and genetic toxicity were observed. The safety of the herbal pilatory for external use is acceptable.
4. Relationship of preoperative blood lymphocyte-to-monocyte ratio with the clinicopathological features and prognosis of penile cancer
Journal of Medical Postgraduates 2019;32(2):153-157
Objective This study aimed to investigate the relationship of the preoperative blood lymphocyte-to-monocyte ratio (LMR) with the clinicopathological features and prognosis of penile cancer. Methods We collected the clinicopathological data on 44 cases of penile cancer treated by surgery in our hospital between January 2000 and January 2018. Based on the preoperative LMR, we divided the patients into a low-LMR (LMR < 3.4, n=21) and a high-LMR group (LMR ≥ 3.4, n=23), compared the clinicopathological features between the two groups of patients, performed log-rank univariate analysis on the prognostic factors, and investigated the independent risk factors affecting the prognosis using the Kaplan-Meier survival curve and COX regression model. Results Log-rank univariate analysis revealed that the tumor diameter, cell grade and LMR were the risk factors affecting the recurrence-free survival (RFS) (P<0.05) and that postoperative lymph node metastasis, invasion of nerves and LMR were those affecting the overall survival (OS) of the penile cancer patients (P<0.05). The median RFS was significantly longer in the high-LMR than in the low-LMR group (26 vs 7 months, P=0.010), and so was the median OS (73 vs 29 months, P=0.045). COX multivariate survival analysis showed preoperative LMR to be the risk factor affecting RFS and OS of the patients (P < 0.05). The tumor recurrence rate was significantly lower (HR = 0.398, 95% CI: 0.174-0.909) and the OS rate markedly higher (HR = 0.428, 95% CI: 0.185-0.994) in the high-LMR than in the low-LMR group. Conclusion Penile cancer patients with a higher LMR have longer RFS and OS and are less susceptible to tumor invasion of the nerves. Preoperative LMR plays a valuable role in predicting the postoperative survival of penile cancer patients.

To investigate the influence of such individual factors as gender, age and tissues in vitro to the postmortem interval (PMI) by the Fourier transform infrared (FTIR) spectrometer in animal experiments. SD rats were classified into male and female groups, different age groups (21-day, 42-day and 63-day group), and tissues in vitro and in vivo groups. The rats were sacrificed by cervical dislocation, whose bodies were kept in a controlled environmental chamber set at (20+/-2) degrees C and 50% humidity. The liver, kidney, spleen, myocardium, brain, lung and skeletal muscle tissues were collected for measurement from time zero to 48 h postmortem. With the change of PMI, no obvious changes were found in the main FTIR absorbance peaks and their ratios at different time points. All the experimental groups showed no significant changes when compared with the controls. The gender, age and tissues in vitro were not found to be contributing factors in the estimation of PMI via FTIR spectroscopy.

OBJECTIVETo investigate the feasibility of establishing a murine hemangioma model with injection of recombinant adeo-associated virus mediated human vascular endothelial growth factor-121 (rAAV-hVEGF(121)) gene.
METHODSrAAV-hVEGF(121) was constructed, identified and then implanted to the left back ear of each mouse (1.0 x 10(11)VG in 50 microl per mouse and 10 nude mice received the injection), the rights served as controls with an injection of the same volume of phosphate buffered solution (PBS). The skin color and swelling of left back ear were observed every other day. Histological examination was carried out after mice were sacrificed 2, 4, 6, 8, 12 weeks after injection.
RESULTSThe rAAV-hVEGF(121) was correctly constructed and confirmed by restriction endonuclease analysis, polymerase chain reaction and DNA sequencing analysis. The skin of left back ear became red 2 weeks after injection and gradually exhibited a red lump which was at its utmost 12 weeks after injection. Such phenomena were not observed in right back ear. Histological examinations showed aggregates of endothelial cells by 2 weeks and at 8 weeks the swollen tissue contained many cysts filled with a mass of red cells. CD-34 staining suggested most of the newly-formed cells were endothelial cells.
CONCLUSIONSA hemangioma model was established in mice with injection of recombinant rAAV-hVEGF(121) gene.

BACKGROUND AND OBJECTIVEElastofibroma dorsi has an extremely low incidence. At present, comparative study on imaging manifestations and pathologic findings of elastofibroma dorsi has not been reported in China. This study was to investigate clinical manifestations, computed tomography (CT) and magnetic resonance imaging (MRI) appearances, and pathologic features of elastofibroma dorsi and to improve preoperative imaging diagnosis of this disease.
METHODSThe clinical manifestations, imaging findings, and pathologic appearances of 6 cases of elastofibroma dorsi were retrospectively analyzed and related literatures were reviewed. All patients were examined with MRI, and 4 of them were examined with CT scan.
RESULTSAll patients were above 30 years old without obvious symptoms. The tumors presented as a lenticular soft-tissue mass in the deep subscapular region. The tumor's density on plain CT scan or signal intensity on MR T1-weighted image was approximately equal to that of muscle with some interlaced fat-like areas within mass suppressed by fat-suppression MR sequences, which corresponded to dense collagen tissue and interspersed mature adipose tissue observed microscopically.
CONCLUSIONSCT and MRI can reflect the histological features of elastofibroma dorsi. On the basis of their imaging characteristics, a correct preoperative diagnosis of elastofibroma dorsi can easily be made.

OBJECTIVETo determine the role of serine residues at position 63-84 of CITED1 in the nuclear translocation of CITED1 and osteoblast differentiation.
METHODSWe engineered all the 9 phosphorylated serine residues of CITED1 with a serine-to-alanine mutation at position 63-84. MC3T3E1 cells transfected with pCDNA3-CFP-CITED1 63-84 (9S>A), pCDNA3-CFP-CITED1, and vehicle plasmid were examined with confocal laser scanning microscopy before and after treatment with 100 nmol/L parathyroid hormone [PTH(1-34)] to observe the changes in the intracellular localization of CITED1. The transfected cells were induced for osteoblastic differentiation with mineralized solution in the absence or presence of 10 nmol/L PTH(1-34), and the changes in ALP activity and Ca(2+) concentration were measured; RT-PCR was used to detect the changes in ALP2, RUNX2, and OC gene expressions after the treatments.
RESULTSs PTH(1-34) promoted the nuclear translocation of CITED1 in MC3T3-E1 cells. The (63-84) 9S>A mutation of CITED1 obviously suppressed its translocation and increased ALP activity and Ca(2+) levels in the cells, which led to enhanced mineralization in the cells with also increased expressions of ALP2, RUNX2, and OC.
CONCLUSIONThe serine residues at position 63-84 of CITED1 play a vital role in the nuclear translocation of CITED1 and osteoblast differentiation.
