To discuss the distribution of patents' holders for Chinese herbal compounds in treating cardiovascular and cerebrovascular, the patents' holders for Chinese herbal compounds in treating cardiovascular and cerebrovascular were cluster analyzed by means of simple statistics and cluster analysis. Clustering variables were composed of patent applications, patent maintained number, related papers' quantity, etc. Chinese herbal compound patents' holders were divided into four categories according to their different scientific research and patent strength. It is the magic weapon for Chinese herbal compound patents' holders that have scientific research patents' transforming and make coordination of patent protection and scientific innovation.

Objective To investigate the clinical and pathological characteristics as well as immunophenotypes of subcutaneous panniculitis-like T-cell lymphoma for its differential diagnosis with other similar diseases.MethodsThe clinical、histological and immunophenotypic features of 6 cases were described in detail and related literatures were reviewed.Results All of 6 patients presented with subcutaneous nodules or /and erythematous plaques without lymph nodes swelling and with 5 cases had fever,one case developed to ulcer from its nodules.All of 6 patient presented typical histological changes and 2 of them associated with prominent hemophagocytic syndrome.The neoplastic cells were of T-cell phenotype.Two patients under went an aggressive clinical course with short survival period of 9～16 months and four patients who treated with chemotherapy have an improved survival state,but two of them had recurrence.Conclusion SPTCL is a uncommon type of T-cell lymphoma with clinical and pathological characteristics,and it needs to be differentiated from benign panniculitis or other lymphomas of the skin.

Objective To study the development and research status of infectious diseases influ- ence in China and the academic influence of Chinese Journal of Infectious Disease.Methods Utilizing the literature metrology means,mainly based on《Chinese Journal Full-text Network Database》and《Chinese Citation Network Database》,statistics and analyses on the Cited Papers of Chinese Journal of Infectious Disease in 2000 to 2004 were made.Results The citation rate of 787 papers from 30 issues was 65.9%,citation frequencies in total were 2946 and the highest citation frequency was 245,the av- erage citation frequency was 5.7,and the rate of cited fund articles with total cited papers was 37.6% the total citation frequencies raised in the recent years and the average of influence factors was 1.281. Conclusion The Chinese Journal of Infectious Disease represents the highest level core periodical of infectious diseases in China and is one of the most important information resources in this research demesne.

Objective:To explore the relationship among professional psychological help-seeking intention,mental symptoms,and self-efficacy in adults.Methods:Totally 618 adult samples[286 males and 332 females,304 early adulthood (18-35 years) and 314 middle adulthood (36-60 years)] were selected on the internet.They were assessed with the Intention of Seeking Counseling Inventory (ISCI),Symptom Checklist 90 (SCL-90) and General Self-Efficacy Scale (GSES) to evaluate professional psychological help-seeking intention,mental symptom and self-efficacy respectively.Results:Females and middle adulthood subjects got higher ISCI scores than males and early adulthood subjects [(82.7 ± 6.7) vs.(77.8 ± 7.8),(83.9 ± 6.2) vs.(76.8 ± 7.3);Ps ＜ 0.001].Step linear regression analysis showed that age,scores of self-efficiency,horror and obsessive-compulsive symptoms had positive prediction effect on help-seeking intention (3 =0.34,0.29,0.10,0.11).Mental symptoms,hostility and paranoia had negative prediction effect on help-seeking intention (β =-0.17,-0.15,-0.11),and the 7 variables could explain 45.6％ of the variation.Conclusion:It suggests that the adults' professional psychological help-seeking intention may be related to subject age,mental symptom and self-efficiency.

Objective To explore motivation alteration influencing factors of internet addiction disorder (IAD) undergraduates.Methods The study sampled randomly 793 undergraduates from China University.According to CIAS-R and Young's internet addiction diagnostic criteria,a total of 37 internet addicts were selected.Internet addiction survey was used to study the motivation alteration influencing factors of IAD undergraduates.Results (1) The negative effect of internet using on academy,personal relationship etc.(damage from internet using) had a significant positive correlation with motivation alteration (r =0.672,0.699,0.658,P ＜ 0.01 ; r =0.653,0.673,0.628,P ＜ 0.01 ; r =0.604,0.681,0.703,P ＜ 0.01).(2) Benefit from psychological satisfactory level of internet using had no significant difference with motivation alteration.(3) Self-efficiency of behavioral control on using internet had a significant negative correlation with motivation alteration (r =-0.397,-0.370,P ＜0.05).Conclusion The motivation alteration of IAD undergraduates is influenced by the factors of damage from internet using,sense of achievement,self-efficiency of behavioral control on using internet and so on.

BACKGROUND: Embryonic stem cell (ESC) is a kind of highly undifferentiated totipotent cell. It can proliferate and maintain its totipotency in the system cultured in vitro. It is one of most promising stem cells in thetreatment of central nerve injury.OBJECTIVE: To observe the survival and migration of induced transplanted ESC in mice with spinal injury and hypoxic-ischemic encephalopathy.DESIGN: A completely randomized grouping design, controlled animal experiment.SETTING: Laboratory of Developmental Biology Research Center of Shanghai Second Medical University.MATERIALS: Sixty C57/BL6J mice, of clean grade and either gender, aged 6 to 8 weeks (n =30) and 7 days (n =30)were provided by the Shanghai Experimental Animal Center, Chinese Academy of Sciences [Permission No, SCXK (hu)2003-0003]. This animal experiment was approved by Animal Ethics Committee. Mouse ESC strain S8, labeled LacZ marker gene (Provided by Shanghai Developmental Biology Research Center). X-gal dyeing reagent (Sigma Company).METHODS: This experiment was carried out in the laboratory of Shanghai Developmental Biology Research Center (Shanghai Key Laboratory) from October 2002 to December 2003. ① Experimental grouping of spinal injury: Sixteen C57/BL6J successful mice models, aged 6-8 weeks, were randomized into 2 groups: experimental group (n =8), in which, following right spinal semi-sectioning, derivated cell suspension for inducing the in vitro differentiation of ESC was injected at 1 cm away from injury through vertebral canal, and control group (n =8), in which, following right spinal semi-sectioning, phosphate buffer solution (PBS) was injected at the peripheral region of injury. ② Hypoxic-ischemic encephalopathy experimental grouping: Sixteen successful C57/BL6J mice models, aged 7 days, were randomized into 2 groups: experimental group (n =8), following ligation of right common carotid artery, mice were placed in the closed container containing 0.08 volume fraction of oxygen and 0.92 volume fraction of Nitrogen gas, and taken out 1.5 hours later; 3 μL ESCs were injected into the right cerebral ventricle at about 1 week, and control group (n =8), in which, the same amount of PBS was injected into the right cerebral ventricle. ③ At 12 weeks after transplantation, the survival and migration of induced ESCs labeled by Lac-Z in the spinal cord and brain were observed by zymologic method.MATN OUTCOME MEASURES: Survival and migration of ESCs in the central nervous system.RESULTS: ①After being induced in vitro and transplanted to spinal injured region, ESCs differentiated into neural precursor cells. Neural precursor cells could survive in the injured region and migrate to 5 mm away from injured region.Immunohistochemistry proved that the neural precursor cells of transplanted ESCs could differentiate into neurons.Morphologically, it was proved that neural precursor cells-derived from ESCs could well integrate peripheral tissue. ② The induced ESCs were injected into the lateral cerebral ventricle of mice. Derived ESCs widely distributed in the injured hippocampal region, cerebral cortex ventricle choroid plexus, vascular endothelium and other regions, and integrated peripheral tissue, which were similar to adjacent cells in morphology, suggesting that induced ESCs also could survive for long time and far migrate.CONCLUSION:The induced ESC can survive and migrate in the host injured brain and spinal cord, and the migration of ESCs is more obvious in the brain than in the spinal cord.
