In order to study the status of cell apoptosis in psoriatic epidermis, we have investigated the changes of the lesions in various stages in patients with psoriasis vulgaris by using terminal deoxynueleotidyl transferase-mediation dUTP-biotin nick end labelling (TUNEL). The results showed that the highest frequency of apoptotic keratinocytes was observed in the early scaling papular lesions, and the frequency was reduced in the progressive maculo-papular lesions and the coalescent plaques successively. The frequency of hyperproliferation of epidermis was in the reverse order in comparison with the above results. These results suggest that increased apoptosis of keratinocytes is the initial change of psoriatic epidermis, then hyperproliferation of keratinoeytes follows.

ACKGROUND:Autism is a kind of neurobiological disease.The increase of plasma concentration of 5 hydroxytryptamine(5 HT) is considered to be one of study results,which is the most definite and has the best repetition,for the biological investigation of autism. Whether the season of birth and maternal mood during pregnancy are correlated with the occurrence of autism? OBJECTIVE:To compare the differences of the plasma concentration of 5 HT,season of birth and the maternal mood during pregnancy between autistic and normal children,and probe into the cause of increased 5 HT in autism. DESIGN:An observational comparative study taking autistic and normal children as the subjects. SETTINGS:A clinical psychological department of a university hospital;Mental Health Institute of the Xiangya Second Hospital;A rehabilitation center for dumb children of city grade. PARTICIPANTS:Children in the autistic group(n=54),who were in accordance with the diagnostic criteria of autism in Diagnostic and Statistical Manual of Mental Disorders Fourth Edition(DSM IV) and had the total score of social adaptive ability scale(SAAS) over 40, were selected from the Outpatient Clinic for Children of the Mental Health Institute,Xiangya Second Hospital of Central South University and the training class of autism of Shenzhen Special Education School;Children in the normal control group,who had no obvious somatic and neurological diseases,and developing delay detected by physical,neurological and mental status examinations, rough detection of developing level,were selected from the primary school and kindergarten in Changsha and Shenzhen cities. INTERVENTIONS:The plasma level of 5 HT was examined, season of birth and maternal mood during pregnancy were investigated in autistic and normal children.The children with autism were accessed with SAAS. MAIN OUTCOME MEASURES:The plasma level of 5 HT,the season of birth and the maternal mood during pregnancy in both groups. RESULTS:The score of SAAS in children with autism was 67.65± 1.67.The plasma level of 5 HT was(0.78± 0.32) μ mol/L in the autistic group,which was significantly higher than that in the normal control group [(0.62± 0.16) μ mol/L](t=3.17,P=0.002). There were 17 children with autism had increased 5 HT.Compare with normal children,most children with autism were born in winter and spring,and their mother had obvious mood problems during pregnancy. CONCLUSION:The 5 HT level is higher in children with autism than in normal children.Most children with autism were born in winter and spring,and their mother had obvious emotional problems during pregnancy.There are phase of high functioning of 5 HT in mother in key period of fetus cerebra development that may be one of the causes of hyperserotonemia in autism,and that is possibly one of the etiologies of autism.

Malaria vaccines are being developed against different stages in the parasite's life cycle. Although not directly protective ,the sexual stage vaccines would induce antibodies that would prevent infection of mosquitoes when ingestedin a bloodmeal containing sexual stage parasites. pfs25 has been tested to be an important candidate antigen for malarial transmission blocking vaccine . In this report we analyzed the complete code of pfs25 gene of Plasmodium falciparum PFD-3/YN isolate. The result shows that the gene encoding pfs25 of PED-3/YN isolate has a mutant which generates a PstI endonuclease restriction site and shares 99.2% nucleotide homology with that of NF4 isolate.

ObjectiveTo investigate the modification method of Cervical Spine Injury Severity Score System and discuss diagnosis and treatment strategy of lower cervical spine injuries.Methods Treatments of lower cervical spine injuries were selected according to the injury severity graded by the modified Moore' s classification system.Conservative therapy could be adopted for the patients with stability quantification rating < 3 points or for the those with stability quantification rating =3 points but without spinal cord or nerve root compression.Surgical treatment was recommendable for the patients with stability quantification rating =3 points and with spinal cord or nerve root compression.Surgical therapy could be required for the patients with stability quantification rating ≥4 points and with risk of lower cervical instability.The higher the stability quantification score implied the stronger the surgical indications.Lower cervical spine injury combined with spine cord or nerve root compression had absolute surgical indications.At the same time,therapies were selected based on patients' other factors.ResultsBased on basic principles of the modified Moore' s classification system together with opinions of the patients and their relatives,14 patients were managed with surgical treatment and 16 with conservative treatment.Among the patients with complete spinal cord injury (Grade A),two patients treated surgically showed no obvious signs of spinal function recovery,but their nerve root irritation symptoms disappeared; the other one patient who needed surgery but received conservative treatment had no change of the spinal cord function and nerve root irritation.The patients with incomplete spinal cord injury (Grades B,C and D) treated surgically obtained certain degree of spine cord function recovery,with their American Spinal Injury Association (ASIA) score raised by 0.5 grade on average.However,the patients who needed surgery but received conservative treatment gained average increase of ASIA score for 0.5 grade.Imaging examination showed that patients without combined spinal injuries obtained interbody fusion after surgery,with normal alignment and height of the cervical vertebra but without presence of vertebral shift or instability. ConclusionsThe modified Moore' s classification system takes patients' spiaal injury condition and other factors into consideration in selection of conservative or surgical treatment,which improves the Cervical Spine Injury Severity Score System to some extent and has prospect of clinical application.
