Objective To investigate the clinical values of serum amyloid A (SAA) and hypersensitivity C reactive protein(hs-CRP) in the diagnosis of postoperative infection in patients with ovarian tumor.Methods Clinical data of 679 patients with ovarian tumor were retrospectively analyzed.According to the development of postoperative infection or not,all patients were assigned into infection group(n =45) or non-infection group(n =634).The primary outcomes indicators were SAA,hs-CRP,C reactive protein(CRP) and white blood cell.Results Compared with the non-infection group,the infection group got a significantly higher levels of SAA [(104.73 ± 34.74) mg/L vs.(6.12 ±0.74) mg/L,t =25.546,P =0.000] and hs-CRP [(142.35 ± 43.84) mg/L vs.(18.45 ± 5.39) mg/L,t =24.595,P =0.000] and white blood cell [(11.48 ± 3.59) × 109/L vs.(7.49 ± 2.83) × 109/L,t =6.305,P =0.000] and CRP [(32.58 ± 10.48) mg/L vs.(16.34 ± 8.47) mg/L,t =8.496,P =0.000].The area under the Receiver Operating Characteristic of SAA,hs-CRP,white blood cell and CRP were 0.879 (95% confidence interval:0.825 ~ 0.920,P =0.000),0.858(95% confidence interval:0.792 ~0.925,P =0.000),0.737(95% confidence interval:0.658 ~0.817,P =0.000) and 0.767 (95 % confidence interval:0.713 ~ 0.822,P =0.000).Z tests showed that the areas under the curve of SAA and hs-CRP in the diagnosis of postoperative infection in patients with ovarian tumor were higher than white blood cells and CRP(all P < 0.05).Conclusion SAA and hs-CRP have better diagnostic values in the postoperative infection of ovarian tumor,and it is worth to be popularized.

Objective To study the inhibition of AP-1 transcription factor activity by Hint1 gene over expression in HepG2 cell lines. Methods The Hintl gene was amplified, and then was inserted into the pcDNA3/HA eukaryotic expression plasmid. The constructed pHA-Hint1 plasmid was confirmed by DNA sequencing. The pHA-Hint1 was transfected into the HepG2 human hepatoma cells. Semi-quantitative RT-PCR and Western-blot were used to detecte the expression of HA-Hint1. The HepG2 cells were co-transfected with pHA-Hint1 and pAP-1/Luc luciferase reporter. At 36 h after transfection, luciferase assay system was used to detect the AP-1 transcription factor activity. Results The constructed pHA-Hint1 was confirmed by DNA sequencing, pHA-Hint1 gene transduction through lipofectine induced over-expression in HA-Hint1 mRNA (t =3.89, P<0.05) and HA-Hintl protein (t=3. 12, P<0.05). Co-transfection of Hint1 gene inhibits AP-1 luciferase activity. Cotransfection with increased concentration of a pHA-Hint1 plasmid (0 μg/ml, 0. 5 μg/ml, 1.0 μg/ml, 1.5 μg/ml, 2. 0 μg/ml) produced a concentration-dependent inhibition of AP-1 transcription factor activity. At the concentration of 1.5 μg/ml, and 2.0 μg/ml, the activity inhibition reaches significant difference ( F = 72. 009, P < 0. 05 ). Conclusion Over-expression of Hintl can, at least in part, inhibit the AP-1 transcription factor activity in HepG2 cells.

Metastatic colorectal cancer (mCRC) is a clinical and molecular heterogeneous disease. Currently, for mCRC, extended rat sarcoma (RAS) testing is recommended in routine clinical practice before any treatment. RAS mutational status is significantly associated with the outcome of patients and strongly predictive for anti-EGFR-targeted therapy. However, specific treatments for RAS target are not yet available. Previous studies have shown that direct inhibition of RAS proteins has limited clinical benefits. Recently, a promising drug, AMG-510, which can directly inhibit KRAS G12C has been reported; however, it needs further confirmation. In the past few years, important advances have also been made in approaches designed to indirectly target RAS by inhibiting RAS effectors, multi-target combination strategies and immunotherapy. They are expected to be effective treatments for RAS target. This article summarizes the precision treatment of RAS-mutant mCRC.

Objective To investigate the relationship between single nucleotide polymorphism (SNP) of Fas ligand (FasL) and fulminant hepatitis B in Han Chinese. Methods HBV infected subjects were enrolled in this case-control study, including 233 cases of inactive HBsAg carrier, 68 patients with fulminant hepatitis B,100 cases of spontaneous hepatitis B clearance, 102 patients with hepatitis B virus (HBV) related cirrhosis and 112 patients with HBV related primary hepatocellular carcinoma. The blood samples and clinical data were collected. FasL-844T/C polymorphisms of enrolled subjects were examined by TaqMan real time fluorescent genotyping polymerase chain reaction (RT-PCR). A adjusted odds ratios (OR)and 95% confidence intervals (CI)were calculated using the Logistic regression model. Results After adjusting the factors of gender and age, binary Logistic regression analyses indicated that the genotype frequencies of FasL-844 CC,CT,TT in inactive HBsAg carriers were 50. 64% ,39. 91% and 9. 44% respectively, and those in cases of fulminant hepatitis B were 79. 41%, 17. 65% and 2. 94%, respectively. The analysis also revealed that FasL-844CC genotype in inactive HBsAg carriers was high risk factor of developing fulminant hepatitis B (OR =4. 729,95%CI:0. 510 - 21. 282,P = 0. 043), while there were no statistic significances in other cases (P>0. 05). Conclusion The inactive HBsAg carriers harboring FasL-844CC may have greater susceptibility to fulminant hepatitis B, which need arouse high attention.

Objective To purify native and recombinant heparin-binding hemagglutinin(HBHA)protein,and investigate the activity of HBHA polyclonal antibody against aggregation of Bacillus CalmetteGuerin(BCG)induced by HBHA.Methods After growing BCG to the stationary phase in the 7H9 liquid medium,the native HBHA protein(nHBHA)was obtained by CL-6B column chromatography.At the same time,the HBHA gene fragment was cloned and expressed by transforming Escherichia coli BL-21.Then the polyclonal antibody against rHBHA was prepared by immunizing rabbit.Different comcentration of the HBHA protein was added to the BCG liquid medium,and the aggregation of the BCG was observed.Then,add the HBHA protein that incubated with anti-HBHA antibodies to the BCG culture medium and observe the aggregation of BCG.Results The purity of native HBHA was 99% and the concentration was 1.016 mg/ml.The expressed product contained 36% of total somtic protein.After purified,the purity of the recombinant HBHA protein was 97.1% and the concentration was 10.98 mg/ml.Both the rHBHA and nHBHA could induce the aggregation of BCG.When then concentration of nHBHA is 0.2μg/ml,BCG could be induced to aggregate,while the rHBHA concentration is 2μg/ml could induce the aggregation.Both aggregations could be suppressed by the polyclonal antibody against rHBHA.Conclusions The native and recombinant HBHA are successfully obtained.It is proved that the rHBHA could induce the aggregation of BCG similar as nHBHA,and polyclonal antibody against rHBHA could also suppress the activity of nHBHA.It suggested that rHBHA could be further used in clinical diagnosis and vaccination.

OBJECTIVETo introduce the application of "tennis racket" flap with fascial pedicle on the healthy chest for radiation ulcer after surgical treatment of breast cancer.
METHODSThe " tennis racket" flap was designed on the healthy chest along the cartilage with fascia pedicle near the sternum. 9 cases were treated. The flaps size ranged from 5.0 cm x 3.5 cm to 13 cm x 11 cm with pedicle size of 2-8 cm in length and 2.0-3.0 cm in width.
RESULTSAll the 9 flaps survived completely with satisfactory appearance. The patients were followed up for 2 months to 3 years without ulcer reoccurrence.
CONCLUSIONSThe "tennis racket" flap has a slender fascial pedicle without major blood vessel. It has the advantages of good flexibility for rotation and large flap size for the reconstruction of the radiation ulcer after surgical treatment of breast cancer.
