The event-related potential (ERP) is considered as one of the most effective methods to study and analyze objectively human mental activity based on nerve electrophysiology. At present, ERP is not only used in the study of lie detection, but also in the clinical medicine for the cognitive assessment on patients with cerebrovascular disease, dementia or traumatic brain injury and auxiliary diagnosis of mental illness. With the further development of ERP detection technology, it would have a wider application prospect in the field of forensic medicine.

Objective To observe the protein and mRNA expression of thyroid-stimulating hormone receptor (TSHR) in mammary gland tissue of lactating rats,and to explore iodine uptake mechanism.Methods Eighty adult Wistar rats (60 female and 20 male),weighting 210-250 g were selected.All female Wistar rats were randomly divided into 6 groups according to their body mass:normal non-pregnant group,lactating for 5-,10-,15-and 20-day groups and weaning for 5 days group,10 rats in each group.All rats were fed with conventional fodder and tap water freely.In addition to the normal non-pregnant group,other five groups of female and male rats were mated at 3 ∶ 1,respectively.Then the rats in all groups were killed on the 5th,10th,15th and 20th day after lactation and on the 5th day after weaning to get the mammary gland tissue.The protein and mRNA expression of TSHR were determined by immunohistochemical staining and real-time quantitative PCR.Results TSHR protein was expressed in mammary acinar and ductal epithelial cytoplasm.The expression of TSHR in mammary gland showed significant differences between groups (x2 =14.612,P ＜ 0.05),the staining intensity of mammary gland tissue in normal non-pregnant rats(weak,n =4; moderate,n =6) was weaker than that of lactating for 5 days(weak,n =2; moderate,n =3; strong,n =5) and 10 days groups(barely detectable,n =1;moderate,n =4; strong,n =5; x2 =4.113,5.250,all P＜ 0.05).The expression of TSHR mRNA in mammary gland showed significant differences between groups(F=20.488,P ＜ 0.05); the expression of TSHR mRNA in lactating for 10 days group(0.31 ± 0.06) was higher than that of lactating for 5 days group(0.22 ± 0.04,P ＜ 0.01),and the expression of lactating for 15 days group (0.16 ± 0.08) was significantly lower than that of lactating for 5 days group (P ＜ 0.05).Conclusions TSHR is widely expressed in mammary gland of lactating rats.The iodine uptake of mammary gland is enhanced in early lactation period when the body may be more susceptible to iodine deficiency,therefore iodine should be supplemented reasonably.

OBJECTIVETo study a new method of simultaneous repair of alveolar cleft and the deformity of the nose and lip.

METHODS42 patients with cleft of alveolar process were included in this study. We filled the cleft of alveolar process with iliac cancellous bone and covered the depression of piriform aperture and the nasal side with iliac cartilage. Simultaneously, we corrected the nasal deformity using V-Y plasty of a mucosa-cartilage compound flap at the nasal vestibule.

RESULTSIn the patients aged 9 approximately 11 years, the mean height of the repaired alveolar process was 86.7%; the mean thickness was 89.6%; the contour and function of the alveolar process was grade I or II. The canine erupted at the place of bone grafting. The depression of the piriform aperture and alae nasi was repaired. The contour of the nares was symmetrical. In the patients over 12 years, the mean height of the alveolar process was 70.1%; the mean thickness was 71.7%; the contour and function of the alveolar process was grade II or III. The deflexion of nasal dorsum and nasal dome was not ameliorated in 2 patients of 18 years old.

CONCLUSIONSThe application of iliac cancellous and chondral bone to simultaneously repair cleft of alveolar process and the nasal deformity is an ideal plastic method. It can recover the height of alveolar process and the continuity of dental arch, ameliorate the nasal deformity, and redress the deflexion of nasal dorsum and nasal end. It can also eliminate the psychological obstacle of the patients at an early stage.

Taking Doctor HUANG Shi-ping as the representative, the school of Huang's golden needle is based on Chinese martial art. Golden needles are adopted as main tool. Attaching great importance on the combination of acupuncture and moxibustioin, it is also characterized with penetrating needling with long needles. Through the development of three generations, it once outshone other schools in the field of acupuncture, and became famous all over the world. It made great contribution to the development of the course of acupuncture. However, with the development of the history, the form of acupuncture education as well as apparatus were all undergone an unified reform. Therefore, Doctor HUANG Shi-ping's acupuncture school be lost gradually.

OBJECTIVETo observe the travel, divisions, and the lengths, diameters, branches, artery supplies of the main segments of maxillary nerve.

METHODSFifty formalin-preserved adult half-head specimens with intravascular injection of red color emulsion were used for the gross and microanatomical studies of maxillary nerve. The lengths, diameters, branches and artery supplies of four main segments of maxillary nerve were observed. SPSS 11.5 software was used to analyze the data.

RESULTSThe length and diameter of cranial middle fossa segment of maxillary nerve were (10.70 ± 1.31) mm and (4.01 ± 0.52) mm respectively, which was supplied by inferior-lateral cavernous sinus artery. The length and diameter of pterygopalatine fossa segment were (16.21 ± 1.80) mm and (3.27 ± 0.62) mm respectively, in which one zygomatic branch, one to three posterior superior alveolar nerves, two ganglion branches and tuberal descending branches; were given off, and the segment was supplied by foramen rotundum artery. The length and diameter of infraorbital segment were (25.73 ± 2.03) mm and (3.30 ± 0.52) mm and it gave off middle superior alveolar nerve (64%) and anterior superior alveolar nerve and was supplied by infraorbital artery. Facial segment gave off superior labial branches, internal and external nasal branches, inferior palpebral branches, buccal branch and zygomatic branch and these branches were supplied by infraorbital artery and superior labial and angular artery originating from facial artery.

CONCLUSIONSUnderstanding of travel and artery supply of maxillary nerve is helpful to regional anaesthesia and surgery for maxillary nerve. Foramen rotundum, sphenopalatine foramen and infraorbital nerve are important marks for endoscopic surgery in pterygopalatine fossa.

OBJECTIVETo explore whether fractional anisotropy (FA) value could be taken as a quantitative indicator for tracing and reexamining amyotrophic lateral sclerosis (ALS), and to analyze the correlation between FA value and integrative medical treatment.

METHODSTotally 18 ALS patients were recruited in this study. All patients received diffusion tensor imaging (DTI) using 3. OT (Propeller HD) MRI twice. Six regions of interest (ROI) were selected to measure FA values. Survival analyses were performed in 11 cases of end point events.

RESULTS(1) Three ROI (cerebral peduncle, posterior limb of internal capsule, and corona radiata) all indicated that FA value was the highest in patients with mild health status scale of amyotrophic lateral sclerosis (ALS/HSS). (2) There was statistical difference in the means of FA values in cerebral peduncle, posterior limb of internal capsule, and corona radiata of 18 cases between initial examination and reexamination (P < 0.01). (3) Kaplan-Meier survival curve showed the survival rate of ALS patients decreased as time went by, with the median survival time of 48 months.

CONCLUSIONSFA value was inversely proportional to the severity of ALS, the more severe, the lower FA values. FA value was an objective indicator for assessing the severity of ALS. ALS is an incurable disease till now. Integrative medical treatment might become one direction for ALS patients.

The chemical property of cinnamaldehyde is unstable in vivo, although early experiments have shown its obvious therapeutic effects on viral myocarditis (VMC). To overcome this problem, we used cinnamaldehyde as a leading compound to synthesize derivatives. Five derivatives of cinnamaldehyde were synthesized: 4-methylcinnamaldehyde (1), 4-chlorocinnamaldehyde (2), 4-methoxycinnamaldehyde (3), α-bromo-4-methylcinnamaldehyde (4), and α-bromo-4-chlorocinnamaldehyde (5). Neonatal rat cardiomyocytes and HeLa cells infected by coxsackievirus B3 (CVB3) were used to evaluate their antiviral and cytotoxic effects. In vivo BALB/c mice were infected with CVB3 for establishing VMC models. Among the derivatives, compound 4 and 5 inhibited the CVB3 in HeLa cells with the half-maximal inhibitory concentrations values of 11.38 ± 2.22 μM and 2.12 ± 0.37 μM, respectively. The 50% toxic concentrations of compound 4 and 5-treated cells were 39-fold and 87-fold higher than in the cinnamaldehyde group. Compound 4 and 5 effectively reduced the viral titers and cardiac pathological changes in a dose-dependent manner. In addition, compound 4 and 5 significantly inhibited the secretion, mRNA and protein expressions of inflammatory cytokines TNF-α, IL-1β and IL-6 in CVB3-infected cardiomyocytes, indicating that brominated cinnamaldehyde not only improved the anti-vital activities for VMC, but also had potent anti-inflammatory effects in cardiomyocytes induced by CVB3.

OBJECTIVETo investigate the expression of Fas/FasL in infantile hemangiomas and discuss the role of Fas/FasL in the pathologic evolution of infantile hemangioma.

METHODThe EnVision immunohistochemical stain and RT-PCR technique was used to examine the expression of Fas/FasL protein and mRNA in the infantile hemangiomas.

RESULTS(1) In the early and middle proliferating stage, a number of infantile hemangioma cells expressed Fas. In the late proliferating stage, the number of positive cells increased obviously and the expression of Fas mRNA was reaching the strongest level. In the early regressing stage the Fas still existed in some cells and after that the expression decreased quickly. (2) Up to the middle proliferating stage, there were a few of FasL(+) cells foound. In the late proliferating stage, the number of FasL(+) cells increased significantly. From the early regressing stage, the number of FasL(+) cells decreased rapidly and disappeared.

CONCLUSIONThere may exist significant correlation between the expression of Fas/FasL and the development of the infantile hemangioma cells. The apoptosis of the infantile hemangioma cells mediated by Fas/ FasL may be the major reason of the spontaneous involution of infantile hemangioma.

Objective To determine the expression of disabled homolog 2 interacting protein (DAB2IP) gene in the basal cell carcinoma (BCC) of the skin,and to investigate its clinical significance.Methods Clinical data were retrospectively analyzed in 105 outpatients and inpatients who received skin mass resection in Department of Dermatology,Guangdong Second Provincial General Hospital and Guangzhou Institute of Dermatology between January 2012 and November 2017.Totally,79 patients with pathologically diagnosed BCC of the skin served as patient group,and 26 patients with pathologically diagnosed skin tag but without other clinical manifestations served as control group.Immunohistochemical staining was performed to determine the expression of DAB2IP in the two groups,and correlations of the DAB2IP expression with the clinical phenotype and pathological features of BCC of the skin were analyzed.Statistical analysis was carried out with SPSS21.0 software by using chi-square test for the comparison of enumeration data.Results The protein expression of DAB2IP was observed in 11 (42.3％) of 26 patients in the control group,as well as in 74 (93.7％) of 79 patients in the patient group,and there was a significant difference in the positive rate of DAB2IP protein between the two groups (x2 =33.50,P ＜ 0.05).The expression of DAB2IP was uncorrelated with gender or age of patients with BCC of the skin,or with the tumor size (all P ＞ 0.05).The positive rate of DAB2IP protein significantly differed between the patients with superficial BCC (5/7) and those with invasive BCC (95.8％,69/72;x2 =6.47,P ＜ 0.05).Of the 79 patients with BCC of the skin,Ki-67 protein was detected in 31 (39.2％),and the cancer cells expressing Ki-67 protein also expressed DAB2IP protein.Conclusion The expression of DAB2IP increases in BCC of the skin,which may be associated with the occurrence and infiltration of BCC of the skin.

Objective·To investigate the relationship between serum level of caveolin-1 (Cav-1) and early neurological deterioration (END) in patients with acute cerebral infarction. Methods·A total of 126 consecutive patients with acute cerebral infarction were recruited from July 2016 to January 2017 in Department of Neurology, the First Affiliated Hospital of Chongqing Medical University. The serum Cav-1 levels of all patients were detected by enzyme-linked immunosorbent assay (ELISA) test. The neurological deficits were assessed by the National Institutes of Health Stroke Scale (NIHSS) and the Glasgow Coma Scale (GCS) at the same time. Compared with the admission baseline NIHSS score, if second motor NIHSS score increased ≥ 1 point or the total NIHSS score increased ≥ 2 points within 3 days after hospitalization, they were classified as END group, otherwise they were classified as non-END group. Multivariable Logistic regression analysis was used to examine the independent predictors of END in the patients. Receiver operating characteristic (ROC) curves were obtained to explore Cav-1 levels in predicting END. Results·Serum Cav-1 levels in END group were significantly higher than those in non-END group [(29.88±19.57) ng/mL vs (16.08±13.37) ng/mL, P=0.000]. Based on the ROC curves, the best cut-off point of serum Cav-1 for predicting END was 16.55 ng/mL. The sensitivity and specificity were 73.33％ and 74.07％, respectively. Multivariable Logistic regression analysis showed that Cav-1≥16.55 ng/mL remained an independent predictor of END (OR=4.936, 95％CI 1.608-15.155, P=0.005). Conclusion·Serum Cav-1 is an independent predictor of END in patients with acute cerebral infarction.
