Objective To prepare a gene chip for detecting polymorphisms on coding region of genes in hepatocellular carcinoma tissuses. Methods Genes harboring in loss regions with high frequency of hepatocellular carcinoma (HCC) were selected, the related information was inquired and the cSNP sequences were obtained in the SNP database of National Center for Biotechnology Information(NCBI).Then the appropriate primers and oligonucleotide probes were designed according to the SNP sites and the gene chip for the detection of SNPs were constructed. This chip includes 48 cSNPs of 25 hepatocellular carcinoma-related genes. The PCR products labeled by Dig-dUTP were hybridized with cSNP chip. Results The sensitivity, influence of probes and reiteration of the chip were detected. The results indicated that the chip was sensitive about 6?10~(-3) ng/?l. The signal of hybridization was down with lower concentrition of probes. By the chip, 7 of polymorphisms of caspase9 ( rs2308941) C→T and DOK2(rs2242241)T→G, 6 of polymorphisms of EGFL3(rs947345)A →G,caspase9 ( rs2308938)C→G and PHGDH(rs1801955)T→A, 5 of polymorphisms of E2F2(rs3218170) G→A,4 of polymorphisms of MUTYH(rs1140507)T→C and BNIP3L(rs1055806)G→T, 1 of polymorphism of TNFRSF1B (rs1061622)T→G were detected in the tissues of 10 HCC. Samples of caspase9 ( rs2308941G) and ( rs2308941A) were verified by PCR-SSCP and sequencing. Conclusion We prepare the cSNP chip of hepatocellular carcinoma-related genes, which can accelerate the discovery of polymorphic markers on hepatocellular carcinoma.

OBJECTIVE: To explore the clinical effects and short-term complications of using free jejunum graft (FJG) to reconstruct the defects by resections of pharyngeal, laryngeal or cervical esophageal cancers. METHOD: Fifty-eight cases of pharyngeal, laryngeal or cervical esophageal cancers were reconstructed with FJG. All cases were analyzed retrospectively. RESULT: The success rate of FJG transplantations was 91.4% (53/58). The incidence of post-operative short-term complication was 43.1% (25/58), which was not related to age or BMI. The most common complication was anastomotic leakage (18.9%), which was not related to per-operative radiation therapy. However, BMI > 25 cases had significantly higher incidence of anastomotic leakage than BMI ≤ 25 cases (P = 0.009). The second and third most common complications were respiratory system complications (10. 3%) and FJG necrosis (8. 6%). Para-operative death rate was 3.4% (2/58). Two-year overall survival rates of hypopharyngeal cancer and cervical esophageal cancer were 49% and 67% respectively. The group with no short-term complications had a slightly better survival rate than the group with short-term complications from the Kaplan-Meier curve, but there was no significant difference (P = 0.103). CONCLUSION FJG is ideal to reconstruct cervical digestive tract circumferential defects with a high success rate and a low mortality. However, the post-operative complication rate is high. Intensive observation, early detection and timely treatment of complications are crucial.

OBJECTIVETo detect central obesity and related adverse cardiovascular disease risk factors by waist-to-height ratio (WHR) among normal weight adults in Chongqing area.

METHODSA total of 20 000 participants aged 18 - 59 from one hour economic cycle of Chongqing area were selected by group sampling method. We measured the height, waist circumference (WC), body weight, blood pressure, blood lipid and blood sugar. Body Mass Index (BMI) and WHR were computed. We analyzed the differences of the correlated indexes between non-central obesity group (WHR < 0.5) and central obesity group (WHR ≥ 0.5) of those had normal weight (18.5 ≤ BMI (kg/m(2)) < 24). And we used logistic regression method to analyze the relation between central obesity and related adverse cardiovascular risk factors.

RESULTSAmong 11 612 normal weight subjects, 1801 (15.51%) participants were normal weight central obesity. Of non-central obesity group and central obesity group, the levels of waist WC were (73.71 ± 5.91) and (84.47 ± 4.58) cm (F = 328.74, P < 0.01); diastolic blood pressure levels were (72.85 ± 10.30) and (78.22 ± 11.90) mm Hg (1 mm Hg = 0.133 kPa, F = 23.62, P < 0.01); triglyceride levels were (1.22 ± 0.95), (1.97 ± 1.91) mmol/L (F = 114.70, P < 0.01); total cholesterol levels were (4.66 ± 0.84) and (5.04 ± 0.92) mmol/L (F = 13.10, P < 0.01); high density lipoprotein levels were (1.41 ± 0.31), (1.25 ± 0.29) mmol/L (F = 29.44, P < 0.01); low density lipoprotein levels were (2.65 ± 0.74) and (3.03 ± 0.77) mmol/L (F = 9.98, P < 0.01); glycemia levels were (4.94 ± 0.82) and (5.25 ± 1.37) mmol/L (F = 47.21, P < 0.01). The results of the logistic regression analysis showed the central obesity normal weight group was 1.28 (1.02 - 1.60), 1.49 (1.20 - 1.84), 2.24 (1.92 - 2.60), 1.77 (1.53 - 2.05), 1.58 (1.15 - 2.16) and 1.31 (1.06 - 1.63) times more likely than the normal group to have significantly elevated levels of systolic blood pressure, diastolic blood pressure, triglyceride, high density lipoprotein, low density lipoprotein and blood glucose.

CONCLUSIONWHR can effectively reflect the normal weight central obesity and the risk factors of cardiovascular disease;the adverse cardiovascular disease risk was high among normal weight central obesity adults.

AIMTo investigate the effects of soy isoflavones (SI) on the expression of Bax mRNA and Ca(2+) -ATPase activity in ovaries of perimenopause rats.

METHODSThe animal model of perimenopause rats was established by unforced aging. 12 month-old presenilins female Wistar rats were administered by intragastric (ig) with low (500 mg/kg), middle (158 mg/kg) and high (500 mg/kg) does of SI for 8 weeks. The expression of Bax mRNA in ovaries were detected by RT-PCR. Ca(2+) -ATPase activity in ovaries and MDA content and SOD activity in serum were detected by chemi-chromatometry.

RESULTSIntervention of SI could significantly decrease the expression of Bax mRNA in ovaries and MDA content in serum, increase Ca(2+) -ATPase activity in ovaries and SOD activity in serum of presenilins rats (P < 0.05 or P < 0.01).

CONCLUSIONSoy isoflavones could down-regulate the expression of Bax mRNA and increase Ca(2+) -ATPase activity in aged ovaries. It is probably one of the mechanisms to improve the function of aged ovaries in perimenopause rats.

Objective:To evaluate the efficacy and safety of stereotactic ablative radiotherapy (SABR) in patients with pulmonary oligometastases.Methods:Clinical data of patients with pulmonary metastases treated with SABR from 2011 to 2018 were retrospectively analyzed. The local control rate (LCR) and overall survival (OS) were calculated by Kaplan- Meier method. log-rank test was used for univariate analysis and Cox’s regression model for multivariate analysis. Results:A total of 214 lung metastases were detected in 159 patients, and the median follow-up time was 43 months. The 1-, 3-and 5-year LCR were 90.1%, 73.9% and 65.8%, respectively. The 1-, 3-and 5-year OS were 73.8%, 43.6% and 11.9%, respectively. Univariate analysis showed that biological effective dose (BED)≥100 Gy was significantly correlated with LCR ( P=0.033). Cox’s multivariate analysis showed that BED and primary tumor source were the independent prognostic factors of LCR ( P=0.023, P=0.043). No>grade 3 adverse events were observed in all patients during treatment. Conclusions:SABR is a safe and effective treatment of lung oligometastases. SABR should be actively aD ministered for pulmonary oligometastases, especially for those with lesions from lung cancer and the radiation dose should be selected as BED ≥100 Gy.
