OBJECTIVETo explore the clinical effects of transforaminal endoscopic spine system in surgical revision of lumbar vertebrae.
METHODSFrom January 2012 to October 2013,14 patients who needed reoperations of lumbar vertebrae were treated using transforaminal endoscopic spine system (TESSYS). There were 8 males and 6 males, aged from 27 to 84 years old with an average of (50.4 ± 18.9) years. Visual analogue scale (VAS) and Japanese Orthopaedic Association Scores (JOA) were compared before and after surgical revision. Macnab standard was used to assess the clinical effect.
RESULTSAll the patients were followed up from 6 to 27 months with the mean of 18 months. Preoperative VAS score was 6.79 ± 1.31, and in a week,3 months and 6 months after operation were 2.50 ± 1.29, 2.21 ± 1.53, 1.64 ± 1.08, respectively, which were all much lower (P < 0.01) than preoperative score. Preoperative JOA score was 12.43 ± 1.95, and the above corresponding postoperative JOA scores were 21.50 ± 3.78, 21.93 ± 4.55, 23.36 ± 4.33, respectively, which were all much higher than preoperative score (P < 0.01). According to the modified Macnab criteria, 5 patients got an excellent results, 7 good, 1 fair and 1 poor. The nerve root injury of L5 occurred in 1 case during paracentesis and no other complications were found.
CONCLUSIONSelecting the appropriate indications using TESSYS in surgical revision of lumbar vertebrae can successfully avoid the operation scar, reduce the surgical complications and obtain satisfactory clinical outcomes.

To establish a detection method of oncolytic adenovirus/p53 and standard of quality control, human telomerase reverse transcriptase (hTERT) promoter, CMV fusion promoter containing hypoxia reaction element (HRE) and p53 gene were identified by vector DNA restriction enzyme digestion and PCR analysis. The result conformed that all modified regions were in consistent with theoretical ones. Particle number was 2.0 x 10(11) mL(-1) determined by UV (A260). Infectious titer was 5.0 x 10(10) IU mL(-1) analyzed by TCID50. In vitro p53 gene expression in human lung cancer cell H1299 was determined by ELISA, and A450 ratio of nucleoprotein in virus infection group to control group was 5.2. Antitumor potency was evaluated by cytotoxicity assay using human lung cancer cell A549, and the MOI(IC50) of this gene therapy preparation was 1.0. The tumor cells targeted replication ability of recombinant virus was determined by TCID50 titer ratio of filial generation virus between human lung cancer cell A549 and human diploid epidermal fibrolast BJ cells after infected by virus with same MOI. TCID50 titer ratio of tumor cell infection group to normal cell infection control group was 398. The IE-HPLC purity of virus was 99.5%. There was less than 1 copy of wild type adenovirus within 1 x 10(7) VP recombinant virus. Other quality control items were complied with corresponding requirements in the guidance for human somatic cell therapy and gene therapy and Chinese pharmacopeia volume III. The detection method of oncolytic adenovirus/p53 was successfully established for quality control standard. The study also provided reference for quality control of other oncolytic viral vector products.

OBJECTIVETo evaluate the therapeutic effectiveness of fusion tumor vaccine in tongue cancer treatment.
METHODSHuman macrophages fused with human tongue carcinoma cell line Tca8113 cell. The fusion cells were selected by magnetic cell sorting (MACS) and cultured. The biological properties of fusion cells and anti-tumor immune response in vitro induced by fusions were observed.
RESULTSIn contrast to Tca8113, the fused cells grew significantly slow in vitro. The expression of MHC I, II antigen of the fusion cells which was detected by flow cytometry (FCM) was higher than that of Tca8113. The fused cells significantly increased the proliferation of mixed lymphocyte and induced their cytotoxicity on parental Tca8113.
CONCLUSIONSThe fusion tumor vaccine of macrophages and OSCC cells increase in vitro immunogenicity significantly. This indicates that fusion tumor vaccine could be a new method of anti-tumor immunotherapy, which has important potentials for effective individualized human OSCC vaccine.

OBJECTIVETo investigate the clinical features of Epstein-Barr virus-related hemophagocytic lymphohistiocytosis (EBV-HLH), to analysis the outcome of HLH-2004 protocol, and to explore the prognostic factors in EBV-HLH patients.
METHODSThe clinical features at onset and outcome of HLH-2004 protocol from 83 pediatric patients with EBV-HLH enrolled from January 2006 to December 2009 in our hospital were analyzed retrospectively. Univariate and multivariate COX regression analysis were used to identify statistically significant prognostic factors.
RESULTS(1) Among the 83 patients, 45 were males and 38 were females. The age of onset ranged from 6 months to 14 years 4 months. 44 patients were treated with HLH-2004, and 3-year overall survival (OS) was (55.8 ± 7.9)%. (2) The most common clinical features of EBV-HLH included high fever, cytopenia, hepatosplenomegaly, and coagulopathy; The respiratory symptoms, angina phlogistic, skin rashes, neurologic abnormality were rare. 97.3% of patients showed an elevation of serum ferritin, liver dysfunction and lipid metabolism disorders was found in most of EBV-HLH patients. 89.0% of patient had hemophagocytosis in bone marrow at diagnosis of EBV-HLH. (3) COX regression analysis revealed that anemia degree, serum albumin < 30 g/L, CD4:CD8 abnormity, NK cell < 3%, treatment protocol were related with the prognosis significantly (P < 0.05).
CONCLUSIONEBV-HLH in pediatric patients has severe clinical feature and poor prognosis. HLH-2004 protocol is an effective treatment for patients with EBV-HLH. Symptomatic treatment can't rescue the patients of EBV-HLH.

OBJECTIVETo study the relationship of protein intake and energy supply with the physical growth in very/extremely low birth weight infant at their early life.
METHODRetrospective survey was performed in Neonatal Intensive Care Unit (NICU) in Peking University First Hospital. Inclusion criteria were preterm infant, birth weight < 1500 g, hospitalization for longer than 2 weeks, discharge with body weight greater than 1800 g. The infants were divided into two groups according to gestational age (GA). GA < 32 weeks and ≥ 32 weeks. Physical growth and its relation with the protein intake and energy supply were analyzed. The predictive value of serum blood urea nitrogen (BUN) on protein intake was studied.
RESULTNinety-three very/extremely low birth weight infants were involved, 69 in GA < 32 weeks group and 24 in GA ≥ 32 weeks group.Compared with GA ≥ 32 group, GA < 32 weeks preterm infants had more weight loss, (9.2 ± 4.4)% vs. (5.0 ± 3.1)%, P = 0.000; slower birth weight recovery (10.6 ± 3.8) d vs. (7.1 ± 2.6) d, P = 0.000; poorer weight gain at 1, 4, 5 weeks of life, (-4.5 ± 9.3) g/ (kg·d) vs. (3.4 ± 6.9) g/ (kg·d), P = 0.000 , (13.5 ± 7.3) g/ (kg·d) vs. (19.2 ± 4.9) g/ (kg·d), P = 0.001, (14.6 ± 5.6) g/ (kg·d) vs. (18.2 ± 4.5) g/ (kg·d), P = 0.031; less energy supply at 1 to 5 weeks (P value was 0.000,0.000,0.025,0.001,0.008 respectively) and less protein intake at 1, 4, 5 weeks of life (P value was 0.009,0.006,0.032). Extrauterine growth retardation (EUGR) was still predominant in our subjects, 47.8% in GA < 32 weeks group, and 95.8% in GA ≥ 32 weeks group, P = 0.000. The incidence increased greater in GA < 32 weeks infants, 43.5% vs. 20.8%, P = 0.000.The duration of weight loss and mechanical ventilation correlated negatively with weight gain rate, respectively β = -0.591, P = 0.000 and β = -0.281, P = 0.005; the average energy supply and time taken to reach full enteral feeding were factors improving weight gain, respectively β = 0.202, P = 0.021 and β = 0.354, P = 0.000. After birth, serum BUN declined gradually. Positive relation showed between average protein intake at 3(rd) week and BUN level at the end of 3 weeks, r = 0.420, P = 0.000. Serum BUN 1.44, 1.49 mmol/L at the end of 3(rd) and 4(th) week were cut-off predictors for protein intake less than 3 g/(kg·d) at related period, sensitivity and specificity were 65.3%, 83.3% and 60%, 80% respectively.
CONCLUSIONNo enough protein intake and energy supply, poor weight gain are critical problems in the management of very/extremely low birth weight infants. Prevention from NEC, appropriate parenteral/enteral nutrition transforming will benefit their physical growth. Low serum BUN after 3 weeks of life is a valuable predictor of low protein intake.

The aim of this study was to identify the relationship between susceptibility of children to acquired aplastic anemia (AA) and HLA-A, -B, -DRB1 alleles. 80 children with AA were enrolled in this study. Among of them, 34 patients collected from tissue typing test centers of Nanfang Hospital; 46 patients were diagnosed at Department of Pediatrics of Sun Yat-Sen Memorial Hospital. In these patients, 48 were males, 32 were females, and with average age 8.1 years old, 6 cases were non-severe AA (nSAA), 74 case were severe AA (SAA). The healthy control group consisted of 109 donors who were from the same area. All the patients and healthy controls were of Han Chinese, and all were unrelated individuals. The polymerase chain reaction sequence specific primers (PCR-SSP) was used to analyze the polymorphism of HLA-A, -B and -DRB1 alleles. Pearson Chi-square or continuity correction or two-sided Fisher's exact test were used. The results showed that the genotype frequency of HLA-B*48:01 and DRB1*09:01 were significantly higher in children with AA as compared with healthy controls (P < 0.05). The genotype frequency of HLA-B*51:01, DRB1*03:01 and DRB1*11:01 were significantly lower in children with AA as compared with healthy controls (P < 0.05). Besides, the results also demonstrated that the genotype frequencies of HLA-B*48:01 and DRB1*09:01 were significantly higher in SAA as compared with controls, the genotype frequencies of B*51:01, DRB1*03:01 and DRB1*11:01 were significantly lower in SAA, as compared with controls. In conclusion, HLA-B*48:01 and DRB1*09:01 are related with children AA, and may be susceptible alleles to the development of children AA. Besides, the expression of HLA-B*51:01, DRB1*03:01 and DRB1*11:01 are low in children with AA, whether they are relative protection alleles of children needs to be further studied.
