The major capsid protein of lymphocystis disease virus isolated from Rachycentron canadum (LCDV-rc) was amplified and analysed. The 457bp DNA core fragment was amplified with the degenerate primers designed according to the conserved sequences of MCP gene of iridoviruses, then the flaking sequences adjacent to the core region were amplified by inverse PCR, and the complete sequence was obtained by combining all of them. The open reading frame of the gene is 1380bp in length, encoding a putative protein of 459 aa with molecular weight 51.12 kD and pI 6.87. Constructing the phylogenetic tree for comparing the MCP amino acid of iridoviruses, the results indicated that LCDV-rc is most homologous to the other Lymphocystis viruses and all of them constitute a branch. Accordingly LCDV-rc is identified as Lymphocystivirus.

OBJECTIVETo establish the Chinese Pediatric Evaluation of Disability Inventory (PEDI) norms in Chongqing, China.

METHODSPEDI (English version) was translated into Chinese and proof read by back-translation. A total of 1 140 children stratified by age were randomly selected from Chongqing and evaluated by the Chinese version of the PEDI. The obtained data were statistically analyzed.

RESULTSOf 1 140 questionnaires, 1 075 (94.3%) were valid. The data showed that the raw and scale scores of PEDI increased with age, but the standard scores did not increase with age. The raw, scale, and standard scores on self-care and social function scales were significantly lower than American PEDI norms in some age periods (P<0.05), but the raw, scale, and standard scores on mobility scale were not significantly different from American norms (P>0.05).

CONCLUSIONSThe PEDI norms in Chongqing have been successfully established, and can be used to assess the daily function in children, judge the degree of daily function impairment, evaluate the effect of rehabilitation training, and make the rehabilitation plan for disabled children.

OBJECTIVETo explore the "hemi-clamshell" approach to the resection of the apical chest tumors, and to evaluate its advantages of operative safety and completeness.

METHODSWe conducted a retrospective review of the records of 27 patients undergoing resection of the primary apical chest tumors from January 1995 to January 2001. Tumor type included NSCLC, sarcoma, neurofibromatosis, esophageal carcinoma. Data collected included clinical presentation, tumor type and involvement, type of resection, complication, and survival.

RESULTSA clinical operation for gross-total resection of tumors and invaded structures was performed on six patients by means of a successful anterior approach. Among other 21 patients on whom a clinical operation was performed by posterior approach, only 13 patients obtained gross-total resection. There were significant difference between the two groups (P < 0.01). The mean duration for follow-up was 29 months, and the overall median survival was 21 months. Median survival in patients undergoing gross-total resection was 29 months, and this is significantly better than in incomplete resection group (P < 0.01).

CONCLUSIONSThe anterior "hemi-clamshell" approach is a successful technique for the exposure and resection of these tumors and invaded structures. Release of symptoms and long-term survival is acceptable if complete resection can be performed.

Objective To explore the effect of clinic professional nursing guidelines in nursing admini stration.Methods Clinic professional nursing guidelines were formulated according the specific condition in different apartment,the content includes two parts: routine disease care and symptom nursing guideline.Five departments of respiratory medicine,neurosurgery,oncology,orthopedic surgery and oncology radiation were randomly selected as studying subjects and the data was compared before and after guidelines.Results Neurosurgery was selected as a representation,basic nursing quality as(2.223 ±0.315),satisfaction degree was(41.26 ±3.25)before guideline and(3.122 ±0.214)and(46.12 ±5.26)after guideline respectively.The differences were statistically significant (t =21.833,12.740; P＜0.05 or ＜0.01).Conclusions Application of clinic professional nursing guidelines could standardize the nursing behavior and provide scientific,accurate,professional and practical nursing guidelines for first-line nurses,especially for those on further training,new graduate and new to switch department nurses,and raise the work effect and guarantee the work quality,reduce the nursing risk and ensure the nursing safe for them.
