Perception, affection and consciousness are basic psychological functions of human being. Affection is the subjective reflection of different kinds of objects. The foundation of human being's thinking is constituted by the three basic functions. Affective computing is an effective tool of revealing the affectiveness of human being in order to understand the world. Our research of affective computing focused on the relation, the generation and the influent factors among different affections. In this paper, the affective mechanism, the basic theory of affective computing, is studied, the method of acquiring and recognition of affective information is discussed, and the application of affective computing is summarized as well, in order to attract more researchers into this working area.

3.Clinical and imaging features of hypothalamic hamartoma in children.
Chinese Journal of Contemporary Pediatrics 2009;11(5):364-366
OBJECTIVETo study clinical and imaging features of hypothalamic hamartoma in children.
METHODSImaging findings and clinical manifestations of 38 children with hypothalamic hamartomas were retrospectively reviewed. The patients included 25 boys and 13 girls, ranging in age of onset from 1 month to 15 years. All the 38 patients were examined with pre-contrast and post-contrast T1 weighted MR imaging and with non-contrast T2 weighted MR imaging. Meanwhile, 10 patients received CT scan. Hypothalamic hamartomas were confimed by pathologic examinations in the 38 patients.
RESULTSGelastic epilepsy, precocious puberty, other types of epilepsy and disturbance of intelligence were main manifestations in the 38 patients. Gelastic epilepsy was found as an initial clinical symptom in 17 cases, precocious puberty in 13 cases and other types of epilepsy in 8 cases. All masses were located in the suprasellar and interpeduncular cistern. They showed iso-density on CT scan, and homogeneous signal iso-intense to gray matter on T1 and T2 weighted MR images. With contrast MR images, there was no enhancement in the mass. The size or pedunculation of the mass was not correlated with clinical features.
CONCLUSIONSHypothalamic hamartoma may be characterized by precocious puberty and/or gelastic epilepsy and specific imaging findings mentioned above.

In order to identify Peucedani Radix, Peucedani Decursivi Radix and their adulterants, the internal transcribed spacer 2 (ITS2) regions of Peucedani Radix, Peucedani Decursivi Radix and their adulterants were amplified and bidirectionally sequenced based on the Principles for Molecular Identification of Traditional Chinese Materia Medica Using DNA Barcoding, which has been promulgated by Chinese Pharmacopoeia Commission. Sequences were analyzed and assembled by Codon Code Aligner V3. 7.1. The relevant data were analyzed by MEGA 5. 0. Species identification analyses were performed by using the nearest distance methods and neighbor-joining (NJ) methods. The result showed that the ITS2 sequence lengths of Peucedani Radix were 229-230 bp and the average intra-specific genetic distances were 0.005. The ITS2 sequence lengths of Peucedani Decursivi Radix were 227 bp and the sequences contained no variation site. The average inter-specific K2P genetic distance of Peucedani Radix, Peucedani Decursivi Radix and their adulterants species were 0.044 and 0.065 respectively. The minimum inter-specific divergence is larger than the maximum intra-specific divergence of Peucedani Decursivi Radix. The nearest distance methods and NJ trees results indicated that Peucedani Radix, Peucedani Decursivi Radix and their adulterants species could be identification clearly. The ITS2 regions can stably and accurately distinguish Peucedani Radix, Peucedani Decursivi Radix and their adulterants.

Objective To explore the clinical features,diagnosi s and prognosis of incontinentia pigmenti.Methods Analyzing and summarizing the clinical characteristic, diagnosis and prognosis of neonatal incontinentia pigmenti in 6 neonatal infants that were hospita- lized in our department during the period from January 1 998 to December 2003 were studied,and some relevant literature were reviewed. Results 1.Three of 6 infants were male which was unusual;2.Four infants had typical skin lesions at birth and 1 case at 6 days old.Four cases had typical 3 stages o f skin lesions including the erythematous and vesicular inflammatory stage,verr ucous lesions and hyperkeratosis stage,macular hyperpigmentation stage,but the re was overlap;3.Four infants were complicated by central nervous system involv ement (two cases presented mental retardation,2 infants were temporary damage). Two cases were complicated by ocular manifestations ( one case had optical nerve atrophy and blind in left eye,the other had severe bilateral retinal lesions); 4.On specific examination 5 infants were diagnosed by skin biopsy.Gene analysis was made in 1 case,but we didn′t find the mutations of NEMO. Conclusions Incontinentia pigmenti is a rare X-linked dominant multisystem disease.It may be misdiagnosed in the initial stages.Except typical clinical features,skin biops y and gene analysis are main evidence for diagnosis.Early detection and interven tion are important for prognosis.

Objective To improve the recognition of intramedullary spinal abscess by a case of congenital dermal sinus with intramedullary spinal abscess and reduco the incidence of congenital dermal sinus with intramedullary spinal abscess.Methods Clinical,laboratory data and image of a confirmed case about one infant of congenital dermal sinus with multiple intramedullary spinal abscess were investigated,the related literature was reviewed.Results In this case,when the infant with congential dermal sinus had infection,he failed to gain antibiotic therapy, timely surgical treatment,his infection had diffused, and multiple intramedullary spinal abscess flared up.Conclusions Intramedullary spinal abscess is a rare disease.If treatment is delayed, the prognosis is poor and the mortality rate is high.MRI is the ideal investigation for diagnosis.Intramedullary spinal abscess can happen subsequent to congenital dermal sinus with infection, and cause neurological sequela. So an infant with congenital dermal sinus should be offered to avoid complication caused by infection.

Background Researches documented that retinal nerve fiber layer thickness (RNFLT) in unaffected carriers of Leber hereditary optic neuropathy (LHON) becomes thickened in different quadrants to different degrees.But the change of their macular thickness is still unclear.Objective This study was to clarify RNFLT and macular thickness by optical coherence tomography (OCT) in unaffected female carriers of LHON families.Methods Five female LHON patients (5 eyes) from 5 LHON families,eighteen unaffected female carriers (18eyes) from 18 LHON families and twenty-five age-matched healthy female controls (25 eyes) were included in this study.The patients and genetic carriers were diagnosed in PLA General Hospital from 2011 September to 2012 October.Regular ocular examination were performed followed by OCT measurement of retinas.The Optic Disc Cube 200×200 and Macular Cube 200×200 protocols were used during the OCT measurement.Average (360°) RNFLT,RNFLT at four quadrantic sections,cube average macular thickness and macular thickness of nine Early Treatment Diabetic Retinopathy Study (ETDRS) sub-areas were compared among the LHON genetic carriers,LHON patients and normal controls.Results Compared to the normal control group,significant reduced values were seen in temporal,superior,nasal and inferior side of sub-area macular thickness in the LHON female carriers (P=0.022,0.046,0.024,0.008).In addition,but no significant differences were found in cube average thickness,central subarea macular thickness,temporal,superior,nasal and inferior side of lateral sub-area macular thickness,average RNFLT,and temporal,superior,nasal and inferior quadrant RNFLT between the LHON female carriers and normal controls (P=0.102,0.051,0.238,0.663,0.1 10,0.104,0.419,0.371,0.158,0.063,0.563).Compared to the unaffected female carrier group,female patients showed significant reductions in cube average macular thickness,temporal,superior,nasal and inferior side of sub-area macular thickness,temporal,superior,nasal and inferior side of lateral sub-area mac ular thickness,average R NFLT and temporal,superior,and inferior quadrant RNFLT (P =0.000,0.000,0.000,0.007,0.002,0.002,0.000,0.000,0.040,0.000,0.016,0.000,0.000) except for the central subarea macular thickness and nasal quadrant RNFLT (P=0.388,0.580).Conclusions Unaffected LHON female carriers show a normal peripapillary RNFLT,but the macular thickness at medial sub-area is thinner.This first report offers an information of macular structure change in unaffected LHON female carriers,which suggest that macular damage appears prior to RNFLT change.

Objective:Accumulating evidences prove that macrophages affect tumor initiation and prognosis. Especially,tumor-associated macrophages (TAMs) are considered to enhance tumor growth,progression,angiogenesis,invasion and metastasis. Furthermore,tumor suppressive microenvironment can " reeducate" and polarize the phenotype and function of TAM. Recently, researchers use different ways to interfere and modify the phenotype and function of macrophages,to improve the recognition, phagocytosis and antigen presentation of macrophage,and enhance its antitumor activity. We will discuss the pro-tumorigenic properties of macrophage and TAM-targeting therapy as a promising novel strategy for tumor immunotherapy.

OBJECTIVETo elucidate the significance of detecting cytokeratin gene (CK-20 mRNA) expression in metastatic lymph nodes of colon carcinoma patients.
METHODSThe expression of CK-20 mRNA was detected in 342 lymph nodes by reverse transcription-polymerase chain reaction (RT-PCR) in 49 colon carcinoma patients. Its incidence was compared with that by routine pathologic examination.
RESULTSThe positive rates of detecting metastasis in the lymph nodes were 21.9% by RT-PCR and 11.1% by routine pathologic examination.
CONCLUSIONThe detection of cancer metastasis in the lymph nodes in colon carcinoma is almost doubled (21.9% vs 11.1%) by CK-20 mRNA, which may provide a guiding significance in staging, treatment planning and prognosis in the prognostic estimation of colon carcinoma patients.
