Objective To study the expression and diagnostic values of long non-coding RNA(IncRNA)metastasis-associated lung adenocarcinoma transcript 1 (Malat-1),p21 and growth arrest-specific 5 (GAS5)in colorectal cancer tissue.Methods Coloreetal cancer of early stage and advanced stage(including paracareinoma tissue),precancerous lesion,benign tumor and noncancer lesion groups were collected,33 cases in each group.The levels of Malat-1,p21 and GAS5 in colorectal tissue of the 6 groups were detected by reverse transcription-polymerase chain reaction(RT-PCR).Serum carcinoembryonic antigen(CEA)and carbohydrate antigen19-9(CA19-9)were detected by ELISA.Results RT-PCR showed the levels of Malat-1,p21 and GAS5 were significantly higher in colorectal cancer of early and advanced stage and precancerous lesion than in the paracarcinoma lesion,benign tumor and non-cancer lesion(P＜0.05).Malat-1,p21 and GAS5 were the highest in the advanced stage group(P＜0.05).The levels of CEA and CA19-9 in non-cancer lesion were the least(P＜0.05).The AUC of ROC analysis operator characteristic curve(ROC)of Malat-1,p21 and GAS5 was comparable(P＞0.05).Pathological changes showed the pathological changes in colorectal cancer of early stage,advanced stage and precancerous lesion were more significant than those in the paracarcinoma lesion,benign tumor and non-cancer lesion (P＜ 0.05),which were the most significant in the advanced stage group.Conclusion The levels of Malat-1,p21 and GAS5.in colorectal cancer tissues could be good indicators for colorectal cancer diagnosis.

Increased plasma total homocysteine (tHcy) and high sensitivity C-reactive protein (hsCRP) levels are independent risk factors for cardiovascular disease. However, the predictive value of tHcy in combination with hsCRP in patients with stroke is not known. To determine the relationship between tHcy and hsCRP, we enrolled 291 patients with first-onset stroke (196 ischemic and 95 hemorrhagic). Plasma tHcy and hsCRP levels were measured and subsequent vascular events and deaths were determined over a 5-year period. Using the arbitrary cutoff for tHcy (<18 μmol/L and ≥18 μmol/L) and hsCRP (<1 mg/L, 1-3 mg/L and >3 mg/L), the patients were divided into 6 groups. Survival analysis showed that the probability of death or new vascular events during a 5-year follow-up increased according to tHcy and hsCRP levels (P<0.01). The relative risk (RR) of death or new vascular events was 4.67 (95% CI, 1.96 to 11.14, P=0.001) in patients with high tHcy (≥18 μmol/L) and hsCRP (>3 mg/L) compared with those with low tHcy (<18 μmol/L) and hsCRP (<1 mg/L). The increased tHcy level (≥18 μmol/L) combined with increased hsCRP level (>3 mg/L) was still significantly associated with the risk of death or new vascular events (RR, 4.10, 95% CI, 1.61 to 10.45, P=0.003) even when adjusted for other risk factors at inclusion. The combination of increased tHcy and hsCRP levels had a stronger predictive value than increased hsCRP alone or increased tHcy level alone. Further studies are required to evaluate the potential decrease in risks associated with lowering both Hcy and hsCRP levels in patients that present with both increased tHcy and hsCRP.

Objective To study the expression of KISS-1 in normal endometrium and in ectopic endometri-um patients with endometriosis. Methods The expression of KISS-1 in 55 cases of normal endometrium as well in 46 cases of ectopie endometriurn with endometriosis were detected by immunohistochemicai EliVision plus method. Results The positive expression rates of KISS-1 in ectopic endometriotic tissues and in normal endometri-urn were 30.43 % and 63.64 % respectively ,and the positive expression rates in ectopic endometriotic tissues signifi-cantly lower than those in the normal endometrium( P< 0.01, P < 0.05). Conclusion The decreased expression of KISS-1 may be related to the mechanism of endometriosis.

Objective To investigate the clinical efficacy,indications and complications of transcatheter arterial embolization for the treatment of traumatic hemorrhage of liver.Methods Retrospectively analyzed 33 cases of traumatic hemorrhage of liver admitted to West China Hospital from May 1996 to May 2006.Twenty-four cases underwent hepatic arterial angiography and were diagnosed as hepatic arterial pseudoaneurysms and followed by superselective embolization of the feeding vessel with gelatin sponge and/or spring coils.Results Embolization was succeeded technically in 28 pseudoaneurysms of 24 cases.Rebleeding occurred in 2 cases and a second embolization was performed with one recovered uneventfully.The other died of rebleeding and severe abdominal infection one week after the second embolization.Fever unrelated to embolization occurred in 9 cases.Conclusion Transcatheter arterial embolization is safe,prompt and effective for the treatment of hemorrhage due to hepatic injury.(J Intervent Radiol,2007,16:226-228)

Objective To explore the preventive effect of twin-tube laryngeal mask airway on gastric lavage and aspiration pneumonia. Methods Between January 2015 and June 2017, 305 cases of poisoning coma patients were admitted to Emergency Department, The First Affiliated Hospital of Nanchang University. According to the inclusion criteria and exclusion criteria, 255 cases of poisoning coma patients were enrolled and randomly(random number) divided into 3 groups (n=85 in each group):group A (normal gastric lavage machine method), group B (gastric lavage endotracheal intubation), and group C (gastric lavage twin-tube laryngeal mask airway placement). Whether there was aspiration pneumonia within 12 hours after the onset was observed, and the length of hospital stay, hospitalization cost and mortality were recorded. The mean value of the two samples was compared with t test, and the four-grid data were checked by chi-square test. P<0.05 was statistically significant. Results Compared with group A, the incidence of aspiration pneumonia was significantly lower in group B and group C (group A 56.47％, group B 32.94％, group C 23.53％, P<0.01). Compared with group A, the length of hospital stay in group C was shorter [(3.39±2.12) d vs. (6.06±4.91) d,P<0.05], and the hospitalization cost was less [(25687.52±20803.44) yuan vs. (52213.91±37267.56)yuan,P<0.05]. There was no significant difference of mortality between the three groups (P>0.05).Compared with group B, the length of hospital stay in group C was shorter [(3.39±2.12) d vs.(5.51±4.37) d, P<0.05], and the hospitalization cost was less [(25687.52±20803.44)yuan vs.(50887.82±32399.76) yuan, P<0.05]. There was no significant difference of mortality between the three groups (P>0.05). Conclusions Twin-tube laryngeal mask airway for poisoning coma patients with gastric lavage, can not only ensures effective ventilation, but also reduces the probability of concurrent aspiration pneumonia, shortens hospital stay, and reduces hospitalization cost, but has no obvious effect on mortality.

Objective To study the expressions of Eag1 and vascular endothelial growth factor (VEGF) in colorectal cancer,and to explore the relationships between Eagl and VEGF expressions and clinicopathologic features of colorectal cancer.The correlation between Eag1 and VEGF and their clinical significance in colorectal cancer were explored.Methods A total of 73 cases of colorectal cancer tissues,25 cases of colorectal adenoma and 10 cases of normal colorectal mucosa from January 2015 to December 2016 in Hunan Provincial People's Hospital were collected.The expressions of Eag1,VEGF protein and mRNA in 73 cases of colorectal cancer tissues,25 cases of colorectal adenoma and 10 cases of normal colorectal mucosa were detected by immunohistochemistry and real-time fluorescence quantitative polymerase chain reaction (RT-qPCR).The relationships between the two factors and the clinical pathological features of patients with colorectal cancer were analyzed.Results Immunohistochemistry showed that the positive rate of Eag1 in colorectal cancer group was 86.30％ (63/73),which was significantly higher than that in colorectal adenoma group (20.00％,5/25) and normal colorectal mucosa group (10.00％,1/10),with significant differences (x2 =38.539,P ＜0.001;x2 =24.874,P ＜ 0.001).The positive rate of VEGF in colorectal cancer group was 89.04％ (65/73),which was significantly higher thah that in colorectal adenoma group (56.00％,14/25) and normal colorectal mucosa group (30.00％,3/10),with significant differences (x2 =10.980,P ＜0.001;x2 =16.911,P ＜0.001).There was a significant positive correlation between Eag1 and VEGF in colorectal cancer and colorectal adenoma tissues (c =0.580,P =0.010;c =0.669,P ＜ 0.001).The results of RT-qPCR showed that the expressions of Eag1 and VEGF mRNA in colorectal cancer group,colorectal adenoma group and normal colorectal mucosa group were 4.50 ±0.34,3.14 ±0.44;1.42 ±0.22,1.61 ±0.15 and 1.00 ±0.16,1.00 ±0.53,respectively,and the differences were statistically significant (F =15.546,P =0.014;F =5.363,P =0.025).The relative expression levels of Eag1 and VEGF mRNA in colorectal cancer group was about 4.50 times (t =31.851,P =0.003) and 3.14 times (t =6.870,P =0.014) than those in normal colorectal mucosa group.The mRNA expression levels of Eag1 and VEGF in colorectal cancer were correlated with degree of differentiation (F =840.725,P ＜ 0.001;F =102.950,P ＜ 0.001),depth of invasion (t =4.754,P ＜ 0.001;t =8.557,P ＜0.001),Duke staging (F =179.902,P ＜ 0.001;F =55.911,P ＜ 0.001) and lymph node metastasis (t =20.337,P ＜ 0.001;t =25.218,P ＜ 0.001).But they were not related to age (t =0.196,P =0.845;t =0.534,P =0.595) and sex (t =0.409,P =0.684;t =1.078,P =0.285).Conclusion Eag1 and VEGF are highly expressed in colorectal cancer tissues with positive correlation,and are closely related to the degree of differentiation,depth of invasion,Duke staging and lymph node metastasis of colorectal cancer.Both of them play important roles in the occurrence and development of colorectal cancer,which is expected to provide favorable research directions to the early diagnosis,treatment and prognosis of colorectal cancer.

OBJECTIVETo explore the possible roles of polymorphisms of SPO11 and glutathionine S-transferase (GST) genes in idiopathic male infertility in a ethnic Han Chinese population from Henan.

METHODSMultiplex PCR and DNA sequencing were performed to determine the SPO11 c.517C>T(rs28368082) and GST genes (GSTM1, GSTT1, GSTP1) polymorphisms in 216 idiopathic male infertility cases and 198 normal samples.

RESULTSThe frequencies of the SPO11 CC and CT genotypes were 87.5% (189/216) and 12.5% (27/216) in the patients, and 97.5% (193/198) and 2.5% (5/198) in the controls, respectively. The frequencies of SPO11 CC and CT genotypes, the A>G transition at nucleotide 313 in the exon 5 of the GSTP1 gene, and the frequencies of combined genotypes GSTM1 (-/-), GSTT1 (+/+), GSTP1 (AA) and SPO11 (CT) were significantly different between the two groups (P<0.05).

CONCLUSIONThe rs28368082 polymorphism of the SPO11 gene, the A>G transition at nucleotide 313 in the exon 5 of the GSTP1 gene, and the combined genotypes of GSTM1 (-/-), GSTT1 (+/+), GSTP1 (AA) and SPO11 (CT) may be associated with idiopathic male infertility in ethnic Han Chinese.
