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.

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 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 clinical pathology of cavernous venous malformations of the body surface.
METHODSTissue samples of cavernous venous malformations from 42 cases were stained with hematoxylin and eosin to observe the pathologic structure. The clinical manifestations and case history were summarized accordingly.
RESULTSThere was no distribution difference of the malformation in sex and body sides, but with obvious difference in anatomic sites. The malformation occurred most frequently at the head and neck, more frequently at extremities and least frequently at the trunk. According to pathologic structure, cavernous venous malformations of the body surface can be divided into three types: the cellular, the canaliform and the mixed.
CONCLUSIONThe cause of distribution difference in anatomic sites remains unclear. Internal hemorrhage and infection may account for the increased growth and ache of the lesion. The different pathologic structure of the malformation may cause different clinical manifestations.

OBJECTIVETo study the recovery method of facial nerve function and to compare the clinical effect after operation of parotid carcinoma, which invades stylomastoid foramen and peripheral bone in deep lobe.
METHODSThree operation methods were taken: (1) The tumor, parotid, invasive facial nerve and bone around the tumor were resected with transplantation of facial nerve. (2) Tumor parotid and facial nerve were resected without transplantation of facial nerve. (3) Tumor and parotid were dislocated from facial nerve, keeping the continuity of facial nerve.
RESULTSFor the first method, facial nerve function of 68.2% patients came back to the patients without facial paralysis before operation, while facial nerve function of 16.7% patients came back to the patients with facial paralysis before operation. There was obvious difference between them (P < 0.05). To the patients with facial paralysis before operation, the first and the second method were taken. The ratio of local control was 33.3% and 10.0% respectively. And survival for 5 years were 25.0% and 10.0% respectively. There was no obvious difference between the two methods (P > 0.05). To the patients without facial paralysis before operation, three methods of operation were taken. The ratio of local control was 77.3%, 48.0% and 33.3% respectively. And survival for 5 years were 86.4%, 52.0% and 41.7% respectively. There was obvious difference between the first method and the other two (P < 0.05). There was no obvious difference between the second and the third methods (P > 0.05).
CONCLUSIONFacial canal dissection in operation of parotid carcinoma with recovery of facial nerve can not only resect tumor completely, but also fit for development of functional surgery. It is an ideal method for surgery operation.
