1.Novel tumor markers for early diagnosis: autoantibodies
Journal of International Oncology 2011;38(5):342-345
Commonly used tumor markers have poor sensitivity and specificity. A lot of research are being conducted searching for the ideal novel serum markers. There are a large number of tumor-associated autoantibodies in cancer patients's serum. Screening and detecting autoantibodies may be used in the early diagnosis of cancer.

OBJECTIVE:To investigate the effect of sertraline on cytokine balance in patients with depression. METHODS: Serum levels of interleukin2(IL-2), interleukin12(IL-12), interleukin4(IL-4), tumor necrosis factor-alpha (TNF-?) and transforming growth factor beta (TGF-?1) were measured in 26 patients with depression(depression group) before and after treatment and 28 healthy volunteers (control group) by enzyme linked immunosorbent assay (ELISA). RESULTS: As compared with control group, in depression group the serum levels of IL-2, IL-12, TNF-? were significantly higher than in control group; the serum levels of IL-4, TGF-?1 were significantly lower than in control group(P

Objective To report the experience of nursing during operation on spina bifida and related diseases.Methods 168 patients with spina bifida and related diseases undergoing spine surgery in the hospital from October, 1989 to October, 2008 were reported. They were 76 males and 92 females, the averaged age was 5.6 years old (from 1 month to 23 years old). There were two follow-ups one month and 6 months to 2 years after operation. Results According to the second follow-up, the neural function improved in 123 cases, didn't change in 32 cases, and deteriorated in 13 cases. Nursing experience included: carefully observed the patients, especially managed respiratory tract and blood pressure; prepared good conditions for surgon to protect the neural function; sponge cushion for the pressured positions.Conclusion Perfect preparation of nursing can facilitate spine surgery on spina bifida and related diseases.

Objective To observe the survival of myoblasts carrying hIGF-1 gene transplanted into the mice, and the expression of hIGF-1 in the transplanted mice. Methods Eighty four male C3H mice(20~30g,7~11w)were divided into four groups: group A, B, C and D (20 mice each group), and the remaining four mice were used as normal control. At the middle of the right gastrocnemius muscle, the mice in group A and B were injected with 1?10~6 myoblasts either carried with or without hIGF-1 gene. Muscle contusion at the middle of the right gastrocnemius muscle of the mice in group C and D was produced. At day 3 following injury, they were injected with 1?10~6 myoblasts either carried with hIGF-1 gene (group C) or without hIGF-1 gene (group D). At the day 2, 5, 10, 20, 30 after injection, four mice of each group were sacrificed randomly. BrdU staining in all mice were performed to evaluate cells surviving, and the expression level of hIGF-1 in group A and C was assessed by immunohistochemical staining and real-time-PCR. Results The BrdU staining in both normal and injured mice transplanted with myoblast carried with or without hIGF-1 were positive. hIGF-1 was expressed and secreted in both group A and C. Conclusion The myoblast carrying hIGF-1 gene transplanted into normal or injured mice can survive for a certain period of time, and can secrete hIGF-1.

Objective To observe the effect of the injection of myoblast carrying human insulin-like growth factor-1(hIGF-1) on the expression of endogenous IGF-1 mRNA and IGF-1 level in mice skeletal muscle following injury.Methods Seventy two male C3H mice(20~30g,7~11w)were randomly divided into three groups(24 mice in each group) with four mice normal controls.Applied a falling hit from certain height at the medial calf of right lower limbs in three groups,the injured skeletal muscle model was successfully simulated.Three days following injury,the mice in group A and B were injected with 1?106 myoblasts either carried with or without hIGF-1 gene respectively and the mice in group C were injected with 100?l saline at the injured muscle.Three mice in each group were sacrificed randomly at day 2,5,10,15,20,30 after contusion.The expression level of mIGF-1 was assessed by immunohistochemical staining and real time PCR.Results mIGF-1 mRNA expression and mIGF-1 factor secretion were observed in all three groups;the amount of mIGF-1 mRNA expression and mIGF-1 secretion in group A were significant higher than that in group B and C.Conclusion Myoblast carrying hIGF-1 transplantation could promote endogenous IGF-1 secretion in injured skeletal muscle.

Objective To study the T cells lineage polymorphism of TCR BV CDR3 in the peripheral blood of ankylosing spondylitis (AS) patients,in order to provide experimental basis for the immunological patho-genesis study of AS.Methods Twenty-six subfamilies of CDR3 T cells of TCR BV in the PBMC of AS patients were amplified by RT-PCR method,then TCR BV CDR3 lineages polymorphism were analyzed by immunization scanning spectrum.Results TCR BV CDR3 scanning spectrum of 20 active AS patients showed abnormal distribution peak,including monoclonal,oligoclonal/oligoclonal trend,skewing peak and irregular abnormal peak.Among them,some subfamilies of 18 patients showed oligoclonal/oligoclonal trend expansion,BV16 and BV18 two subfamilies of one case showed monoclonal expansion.Most spectral type of PBMC TCR BV CDR3 in five normal controls showed Gauss distribution.Conclusion TCR BV CDR3 lineage have significant characteristic polymorphism and spectrum drift characteristics in the peripheral blood of AS patients,which further indicate that T cells has plaied an important role in the immunological pathogenesis of AS.Monoclonal/oligoclonal expansion of T cells may be autoreactive T cells in nature and they may be involved in the pathogenesis of AS.

Objective To evaluated the prevalence of EGFR mutations in Hubei region,to provide reliable experimental basis for reasonable screening TKI beneficiaries in clinic.Methods EGFR mutation of 253 patients diagnosed with NSCLC in Hu-bei region during 2010 to 2015 was detected by PCR-sanger sequencing and ARMS assay,to investigate the sensitivity of dif-ferent methods,to explore the frequency and clinical significance of EGFR mutation in different gender,in different histologi-cal type and different exons.Results 93 of 253 NSCLC patients harbored EGFR mutation,mainly occurred in exon 19 and 21,accounting for 53.76% and 35.38% of the total EGFR mutation rate,respectively.ADx-ARMS method showed higher sensitivity (P=0.001).The mutation detection rate of female NSCLC was significantly higher than that of male NSCLC (P=0.001).The observed incidence of EGFR mutations in patients with adenocarcinomas (38.01%)was the highest in differ-ent histological type,followed by glandular squamous cell carcinoma (30.77%),large cell carcinoma (20%)and squamous cell carcinoma (4.55%).Nonsmoking patients had a higher EGFR mutation frequency (51.6%,81/157)than those with a history of smoking (24%,12/50).Conclusion ARMS assay was more sensitive and more convenient detection method for clinical screening for EGFR-TKI treatment subpopulation.The mutation rate of female NSCLC was significantly higher than that of male NSCLC in Hubei Province.Speculated that the sexual differences in NSCLC with EGFR mutation frequencies were related to hormone levels and smoking status.
