Objective:To investigate the expression of TLR4 mRNA?TLR2 mRNA in the peripheral blood mononuclear cells (PBMC) from the patients with Gram positive and Gram negative infections.Methods:TLR4 and TLR2 mRNA were detected in the patients with Gram negative infections ( n =20) and the patients with Gram positive infections ( n =15) and the normal persons as control ( n =24) with the method of Taqman Real-time PCR.Results:TLR4 mRNA expression in the patients with Gram negative infections were significantly higher than Gram positive infections patients and the normals ( P 0.05).Conclusion:The results showed that the increased expression levels of TLR4 mRNA in PBMC from the Gram negative infectious patients are associated with Gram negative infections and the detection of TLR4 mRNA expression may be a method of diagnosis for Gram negative infections in the early stage.

0.05). Conclusions The high expression of GATA3, a Th2 inducer, may correlate with the disease acti vity of SLE, while T-bet, a Th1 inducer, may not correlate with the disease acti vity.

Objective:To investigate the KRAS gene mutation features in lung and gastric cancers and their relationship with clinicopathologic characteristics. Methods:A total of 128 lung cancer and 115 gastric cancer patients were included. Polymerase chain reaction amplification and DNA sequencing were conducted to detect mutations in exon 2 of the KRAS gene. Results:The mutation frequency of KRAS was different in lung and gastric cancers;however, it did not show any statistical significance (6.3%vs. 4.3%, P>0.05). The KRAS codon 12 gene mutation ranks the first in both types of cancer. No significant correlation was observed between the prevalence of KRAS mutations and patient's age and gender. KRAS gene mutation rate was higher in lung adenocarcinoma than in non-adenocarcinoma, such as squamous cancer (10.7%vs. 0%, P<0.05). Conclusion:No correlation was found between the KRAS gene mutation and the sex and age of lung and gastric cancer patients in Jiangsu Province. The rate of KRAS mutation was low. KRAS gene mutation rate was relatively higher in lung adenocarcinoma patients;thus, the mutation status of the KRAS gene should be evaluated be-fore undergoing EGFR-TKI therapy.

Objective To evaluate the clinical efficacy of thalidomide plus mometasone furoate cream under occlusion and ultraviolet irradiation for the treatment of prurigo nodularis.Methods A non-randomized,parallel,controlled study was carried out.Eighty patients with prurigo nodularis were divided into 3 groups,i.e.,control group(no irradiation),ultraviolet A1(UVA1)group,and ultraviolet B(UVB)group.All the patients were treated with oral thalidomide and topical mometasone furoate cream under occlusion.Additionally,the patients in UVA1 group and UVB group received UVA1 and NB-UVB irradiation,respectively,thrice a week for no less than 8 weeks.Patients were evaluated at the baseline,and on day 30 after the beginning of treatment.Clinical outcome parameters included disease severity score and visual analogue scales for pruritus.Peripheral blood eosinophils were counted during each visit.Rank sum test was performed to compare the clinical efficacy between the 3 groups,and the relationship between peripheral blood eosinophile count and visual analogue scales for pruritus was analyzed.Results After 30 days of treatment,skin lesions were markedly improved in 5 (21.74％),13(43.33％)and 9(37.5％)patients,and improved in 7(30.43％),12(40％)and 7(29.17％)patients,in the control group,UVA1 group and UVB group respectively;a marked response in pruritus was noted in 7(30.43％),18(60.00％)and 14(58.33％)patients respectively in the control group,UVA1 group and UVB group.The efficacy on skin lesions and pruritus was significantly stronger in the UVA1 group and UVB group than in the control group(skin lesions:Z =8.21,5.22,both P ＜ 0.01;pruritus:Z =4.50,4.50,both P ＜ 0.01),but similar between the UVA1 group and UVB group(skin lesions:Z =0.50,P ＞ 0.05;pruritus:Z =0.35,P ＞ 0.05).Peripheral blood eosinophil count was positively correlated with the visual analogue scale for pruritus in the patients(r =0.53,P ＜ 0.01).Conclusions Thalidomide combined with mometasone furoate cream under occlusion and ultraviolet irradiation shows notable efficacy for the treatment of prurigo nodularis,and the combination with UVA1 or NB-UVB irradiation enhances the efficacy of thalidomide and mometasone furoate cream under occlusion.

ObjectiveTo observe the clinical effect of the rehabilitation on the degenerative scoliosis after the interbody fusion and internal fixation.Methods50 patients with degenerative scoliosis and received the interbody fusion and pedicle screw fixation were divided into the rehabilitation group and the control group. Results2 months after operation, the scoliosis coronal Cobb's angle were corrected from (34.11±9.36)° before operation to (23.08±9.16)°. 3 months after operation, the scores of JOA scale, the investigation of quality of life and satisfaction all resulted in better outcome in the rehabilitation group than the control group. ConclusionThe rehabilitation training after operation can reduce complications and improve the quality of life.

This study was aimed to investigate the distribution and implication of tap1 (transporter associated with antigen processing) and tap2 loci allelic and genotypic frequencies. The distribution of tap1 and tap2 loci allelic and genotypic frequencies in 339 random samples of healthy Chinese Hans was analyzed by TaqMan PCR. Several genetic information about power of discrimination, cumulative DP, polymorphism information content, expected heterozygosity and observed heterozygosity were calculated. The results indicated that 5 tap1 alleles (tap1*0101, 020101, 020102, 0301 and 0401) and 4 tap2 alleles (tap2*0101, 0102, 0103 and 0201) were detected in all samples. 8 tap1 genotypes were found which account for 53.3% of the theoretic genotype and 6 tap2 genotypes were found which account for 60% of the theoretic genotype. The genotyping results of tap1 and tap2 both conform to the Hardy-Weinberg expectations (p > 0.05). Tap1*0101 (79.79%) and tap2*0101 (82.74%) are the most common alleles in Chinese Hans. It is concluded that tap1*0101 and tap2*0101 are most common alleles in Chinese Hans, tap1 and tap2 loci carry some power of individual discrimination and polymorphism information content. These two locl can be used for the research in the fields of human genetics, linkage analysis of genetic disease genes, paternity test and individual identification and so on.

Objective To investigate the effects of fast-track surgery on postoperative rehabilitation of patients with liver cancer. Methods Forty-one patients with liver cancer who had been admitted to Zhongshan Hospital of Fudan University from 9 to 30 in July 2008 were randomly divided into fast-track surgery group (n =20) and routine treatment group (n =21) according to the random number table. Patients in fast-track surgery group were preoperatively educated in order to lessen their anxiety. Bowel preparation was not applied before operation, and they were orally administered with 1000 ml of enteral nutrition emulsion (1300 kcal), then they were fasted for 4 hours before operation. Urethral catheter and gastric tube were removed after operation. They were orally administered with 1000 ml of enteral nutrition emulsion on postoperative day 2, and were encouraged to partake in off-bed activity shortly after the operation. The off-bed time, anus exhaust time, postoperative complica-tions, hospitalization time, expense, nutritional and metabolic indexes on postoperative day 1, 3 and 5, hepatic and renal function, immune and stress indexes between the 2 groups were compared by t test and chi-square test. Results There were significant differences in off-bed time, anus exhaust time, patients' weight, expense, total bilirubin level on postoperative day 1, 3 and 5, and level of serum TNF-α on postoperative day 3 between the 2 groups (t =7.065, 5.483, 3.754, 2.291,2.289, 3.218, 3.192, 2.434, 2.089, P <0.05). Conclusions Fast-track surgery can accelerate the postoperative rehabilitation of patients with liver cancer.

Purpose To study the status of EGFR mutations and the expression of excision repair cross-complementation group 1 ( ER-CC1) and Ki-67 protein in patients with non-small cell lung cancer (NSCLC) and to examine the relationship between their expression and clinicopathologic features. Methods EGFR mutations were analyzed with DNA sequencing, and the expression of ERCC1 and Ki-67 protein was examined by immunohistochemistry EnVision. The relationship of EGFR mutations with the expression of ERCC1and Ki-67 and the clinicopathological features were analyzed. Results EGFR mutations were detected in 143 (143/291, 49. 1%) of the 291 specimens. EGFR mutations were found more frequently in women, non-smokers and adenocarcinoma. The difference of EGFR muta-tion rate between the histological subtypes according to the IASLC/ATS/ERS classification of lung adenocarcinoma was significantly ( P=0. 008). The mean tumor diameter was smaller in patients with EGFR mutations than in those with wild-type EGFR (P=0. 020). EGFR mutations were not related to age, lymph node metastasis. However, EGFR mutations were not related to the expression of ER-CC1 and Ki-67 protein (P>0. 050). Conclusions EGFR mutation is closely linked to several clinicopathological factors, such as gender, differentiation, and histological subtype. There is heterogeneity of EGFR mutation in patients with NSCLC. EGFR mutations were not related to the expression of ERCC1 and Ki-67 protein.
