Objective To evaluate the value of serum tumor markers in diagnosis of over 80 years old patients with colorectal cancer.Methods Serum CA199,CA242 and CEA of 68 cases senile patients with colorectal cancer and 35 cases senile patients with benign large intestinal diseases were detected by ELISA.Results Serum levels of CA199,CA242 and CEA in patients with colorectal cancer were (37.95 ± 15.95 ) U/ml,( 50.08 ± 24.20 ) U/ml,( 22.34 ± 17.35 ) μg/L respectively and were significantly higher than that in patients with benign large intestinal diseases CA199 ( 10.73 ± 6.27 ) U/ml,CA242 ( 8.00 ± 3.52 ) U/ml,CEA(2.32 ± 1.01 )μg/L.In addition,the level of these three markers was increased with the progress of colorectal cancer and the sensitivity of diagnosis was related with the stages of colorectal cancer.Parallel combined testing methods increased the diagnostic sensitivity to 83.6％,and serial combined testing increased the diagnostic specificity to 88.7 ％.Conclusions Serum tumor markers showed certain values in the diagnosis of the senile patients with colorectal carcinoma.Furthermore,the combined determination of tumor markers is helpful for early diagnosis of colorectal cancer and increases the sensitivity and specificity in diagnosing of colorectal carcinoma.

Objective To explore the epidemiological character of elderly burn patients and to provide the experience of prevention and treatment.Methods The retrospective study method was used,and totals of 531 elderly patients with burn from January 2002 to December 2010 in two hospitals were selected.Cases information such as demographics,clinical diagnosis,treatments,causes of injury,mortality rate and causes of death since admission and so on was recorded and analysed,then,the epidemiological character was summarized and the prevention and treatment were proposed.Results Among 531 patients with burn,the average age was 72.86,the rate of burn in home was 72.5％ and in accident was 16.70％.The clinical cure rate was 82.11％and the mortality rate was 2.33％.The proportion of the elderly burn patients account for the total admitted patients in the same period was 5.13％ in 2002 and 5.64％ in 2010,and the average age of elderly burn patients was higher from 72.53 years old in 2002 to 73.58 years old in 2010.Conclusions The proportion of the elderly burn patients account for total admitted patients in the same period was higher as well as the average age of patients from 2002 to 2010.We should pay more attention to the prevention and education for the burn in home as the main cause of elderly burn patients is the home burn.

Objective To investigate changes of serum proteins and related enzymes in patients with schizophrenia and its relationship to metabolic syndrome.Methods Five hundred and three inpatients with schizophrenia and 60 healthy volunteer were selected in this study.The demographic information and medical history data of them were recorded and levels of serum proteins and enzymes were measured,and the metabolic syndrome (MS) was diagnosed according to IDF criteria.Results Serum protein contents of schizophrenic patients (total protein (71.14 ±6.13) g/L,albumin (44.56 ±4.24)g/L,globulin(26.35 ±5.04) g/L,apoprotein A(10.97 ± 0.27) g/L,and apoprotein B (0.69 ± 0.25) g/L) were significantly lower than control group (79.96 ± 6.10) g/L,(49.44 ±5.63) g/L,(30.52 ±4.00) g/L,(10.97 ±0.27) g/L,and(0.69 ±0.25)g/L (P＜0.01).Urea nitrogen ((4.36± 1.36) mmol/L) was lower than control group ((5.22 ± 1.31) mmol/L) and C-reaction protein ((3.17 ± 6.58) mg/L) was higher than control group (1.35 ± 1.83) (P ＜ 0.01).Alanine aminotransferase ((24.28 ± 32.76) IU/L),a-L Fucosidase((17.49 ± 4.83) U/L),adenosine dehydrogenase((17.81 ± 5.67) U/L),and creatine kinase isoenzyme((10.50 ±4.92)IU/L) were higher than control group (18.12 ±9.77)IU/L,(15.98 ± 3.58)U/L,(11.75 ±5.48) U/L,and (9.12 ±3.62)IU/L,P＜0.01),but AST isoenzyme ((5.97 ±4.97) U/L)was lower than control group ((7.05 ± 6.72) U/L).Alanine Aminotransferase,alkaline phosphatase,γ-glutamyl transpeptidase,and a-L Fucosidase,AST isoenzyme and cystatin-c of schizophrenic patients with MS were significantly higher than non-MS patients(P ＜ 0.05).Conclusion There are significant metabolic disorders of proteins and enzymes in patients with schizophrenia,and abnormal changes of many enzymes are significantly associated with metabolic syndrome.

RESULTS: Among the 165 therapeutic methods, 277 formulas and 459 kinds of herbs, the methods for activating blood circulation, the formulas for regulating qi-flowing and the herbs for invigorating qi are the most commonly used. CONCLUSION: Therapeutic methods such as invigorating qi, regulating qi-flowing and activating blood circulation are the main choices for PLC, and the methods such as clearing heat, removing dampness and nourishing yin are used as supplements.

Objective:To evaluate the efficacy of femoral primary malignant bone tumors treated by limb salvage, with wide en bloc excision and reconstruction of the defect with recycled pasteurized autogratf.
Methods: From January 2008 to January 2011, 11 patients (7 males, 4 females), aged (11.0±2.5) years suffering from femoral primary malignant bone tumors were treated with en bloc excision and reconstruction of the defect with recycled pasteurized autograft. Ten patients were histopathologically diagnosed with high-grade osteosarcoma, and 1 with Ewing’s sarcoma.According to the Enneking staging system, all patients were in Stage IIb.
Results:All patients were followed-up for 24-65(42±20) months and all showed bony union at the last follow-up. hTe length of tumor bone resection was (17.5±3.2) cm, the operation time was (180±35) min, the intraoperative blood loss was (1200±250) mL, and drainage volume was (650±125) mL. Local skin necrosis occurred in 1 patient (9.1%), which was resolved by debridement. Nonunion occurred in 3 patients (27.3%), who were treated by secondary iliac crest cancellous bone gratfing.Pulmonary metastasis occurred in 1 patient (9.1%) who died 35 months post-operatively. According to the function assessment by the Enneking system, 5 patients had excellent results, 4 had good results, 1 fair and 1 poor results, with a satisfaction rate of 81.2%.
Conclusion:A pasteurized autograft can be an easily accessible and economical alternative for children’s malignant bone tumor of femurs.

Objective To clone human asparagine synthetase(ASNS)gene,express the MS2- ASNS fusion protein through gene engineering and use the purified target protein to immune BALB/C mice, prepare and identify the monoclonal antibody(McAb),which forms the base for studying mechanism of L- asparaginase used as salvage regimen in midline NK/T cell lymphoma nasal type.Methods ASNS gene fragment was amplified by RT-PCR from HepG2 cell line and constructed into prokaryocytic expression vector.Fusion-protein of MS2-ASNS was expressed and used for immunizing BALB/C mice to prepare McAbs against ASNS.Identified the McAb and detected the expression of ASNS in tumor.Results Part of the ASNS reading frame(NCBI,M27396:179-1 420 bp)was cloned and product length of RT-PCR was 1 263 bp.Molecular weight of MS2-ASNS was about 54 700 Da.Two strains of hybridoma secreting ASNS McAbs were obtained.The subtype of the ASNS McAb was IgG2a.Western-blot showed that the McAbs could specifically react with MS2-ASNS fusion protein and ASNS protein in tumor cell lines.ASNS expression was detected by immunocytochemistry and Immunohistochemisrry.Conclusion We have cloned human ASNS gene,obtained the anti-ASNS McAb and examined the expression of ASNS in tumor.

The text has isolated 267 strains LAB from the traditional fermentative food in Sichuan. Using agar plate proliferation experiment and double-layer agar plate proliferation experiment (eliminating the effects of organic acid and H_2O_2, decreased after treatment with trypsin and papain) to screen a LAB of Bacteriocins P158 which has antibacterial action to Escherichia coli, Staphylococcus aureus, Micrococcus luteus, Pseudomonas aeruginosa, Bacillus subtilis. P158 was isolated from fermented glutinous rice. Through detection of its appearance, physiological and biochemical characteristics and 16S rDNA gene sequence homology analysis, it was identified as Lactobacillus plantarum.
