Objective: To investigate the effects of epigallocatechingallate (EGCG) on lipid metabolism related gene and long non-coding RNA (lncRNA) expression proifle by biochip technology, and to explore the possible relationship between the two elements.
Methods: HepG2 cell was cultured with EGCG at 25μmol/L for 24 hours, the total RNA was extracted and hybridized into the biochip of Human Transcriptome Array 2.0 for mRNA and lncRNA expression profile analysis. Bioinformatics technology was used to establish the possible relationship between lncRNA and the predicted target genes;the data obtained from biochip microarray was conifrmed by real time RT-PCR examination.
Results: The microarray revealed that EGCG treated HepG2 cell expressed 27 differential lipid metabolism genes and 11 of them involved in cholesterol metabolism. In addition, there 285 lncRNA expressions were up-or down-regulated. Bioinformatics technology indicated that the predicted target genes for lipid metabolism might be cis-or trans-regulated by lncRNA;the data from real-time RT-PCR was consistent with the data from biochip microarray.
Conclusion: Tea polyphenols improves lipid metabolism and lncRNA might be involved in the regulation of lipid metabolism related gene.

Objective To summarize our experience in the prevention and treatment of iatrogenic vascular(trauma).Methods The clinical data of 24 different types of iatrogenic vascular trauma committed from 2003 to 2006 were retrospectively analyzed.Results The 24 cases included 7 cases of superior mesenteric(arteriovenous) trauma,3 cases of portal venous trauma,4 cases of carotid arterial trauma,6 cases of iliac and femoral arterial trauma,and each one of trauma of popliteal artery,axillary artery,renal artery,left gastric artery,respectively.Treated method: Six cases underwent vascular repair,5 cases had vascular anastomosis,2 cases had vascular replacement,3 cases had vascular ligation,2 cases had covered stent implantation under intervention,and other methods included thrombectomy,thrombolysis and packing.Among the 24 cases,22 were cured completely,one patient died from massive hemorrhage 24 hours after operation,and the other died 5 days after operation.Conclusions Iatrogenic vascular trauma can be prevented and its incidence reduced by increased vigilance,clear identification of the anatomy,and accurate and careful operation.Once iatrogenic vascular trauma has occurred,its cause must be determined and then different treatment methods can be(chosen),based on the cicumstaces. When effective treatment technique is not at hand,one should promptly seek outside support or transfer the patient to an advanced hostipal.

Objective:To investigate the expression levels of matrix metalloproteinase-9 (MMP-9), procalcitonin (PCT), soluble triggering receptor expressed on myeloid cells (sTREM-1) and soluble cell differentiation 14 (sCD14) in pregnant women with premature rupture of membranes (PROM) and their predictive value for chorioamnionitis.Methods:A total of 132 pregnant women with PROM who received treatment in Tengzhou Central People's Hospital from January 2016 to June 2017 were included in the study group. These women were assigned to pre-term PROM group (gestational age < 37 weeks, n = 58) and full-term PROM group (gestational age > 37 weeks, n = 74). A total of 106 concurrent full-term healthy pregnant women were included in the control group. Pregnant women in the PROM group were also assigned into an infection group ( n = 51) and a non-infection group ( n = 81). Serum levels of MMP-9, PCT, sTREM-1 and sCD14 were compared between study and control groups, and their value in the diagnosis of PROM complicated with chorioamnionitis was analyzed. Results:The expression levels of MMP-9 [(271.42 ± 34.16) ng/L], PCT [(54.57 ± 8.16) pg/mL], sTREM-1 [(0.51 ± 0.11) ng/mL] and sCD14 [(60.23 ± 9.49) ng/mL] in the study group were significantly higher than those in the control group [(54.97 ± 10.08) ng/L, (26.04 ± 1.98) pg/mL, (0.19 ± 0.04) ng/mL, (42.04 ± 10.33) ng/mL, t = 27.064, 13.767, 14.831, -13.342, all P < 0.01). The expression levels of MMP-9 [(314.05 ± 45.37) ng/L], PCT [(0.61 ± 0.18) ng/mL], sTREM-1 [(63.12 ± 10.12) pg/mL] and sCD14 [(68.07 ± 11.05) ng/mL] in the pre-term PROM group were significantly higher than those in the full-term PROM group [(238.01 ± 40.45) ng/L, (47.87 ± 8.90) pg/mL, (0.43 ± 0.14) ng/mL, (54.09 ± 10.33) ng/mL, t = 9.103, 8.862, -10.538, 6.494, all P < 0.05). The expression levels of MMP-9 [(343.74 ± 43.74) ng/L], PCT [(69.88 ± 8.83) pg/mL], sTREM-1 [(0.67 ± 0.16) ng/mL], sCD14 [(70.41 ± 8.89) ng/mL] in the infection group were significantly higher than those in the non-infection group [(230.09 ± 49.82) ng/L, (45.82 ± 11.04) pg/mL, (0.42 ± 0.19) ng/mL and (54.41 ± 12.42) ng/mL, t = 23.655, 12.014, 9.382, 11.306, all P < 0.01].

Objective To research early pathological morphology and clinical significance of perforated duodenal ulcer (PDU) closed after non-surgical treatment. Methods Observed morphological changes of duodenal ulcer (DU) lesion with gastroscopy for 302 patients of PDU with non-surgical treatment in early period,when the perforation closed and measured up the clinical indicators during this hospitalization.Results There were 255 patients to be diagnosed with DU caused the perforation. These lesions were characteristic and shown the PDU closed at the bottom and the deep concave ulcers, except for 1 case which complicated by duodenal fistula. These ulcer types were diverse according to the time difference after treatment. No case of re-perforated ulcers or recurrence of peritonitis caused by gastroscopy. Conclusions Deep concave ulcer with A1 phase mainly is an early pathological manifestations of the DU after treated the PDU with non-surgical method characteristically. The wall of the closure of the serosal side is an original form closed perforated ulcer by non-surgical treatment. The risk of perforation associated with the following factors:( 1 )A single DU is located in the anterior wall region. (2)The shape of two kissing DU. (3)The diameter of DU ≥ 1.1 cm. In this case,early diagnosis by using endoscopy is a safe way.

OBJECTIVETo explore the intervention of baicalin on signal transduction and activating transcription factor expression of ulcerative colitis (UC) patients.

METHODSRecruited were UC patients at Outpatient Department of Digestive Disease, Inpatient Department of Digestive Disease, Center for Digestive Endoscopy of College City Branch, Guangdong Provincial Hospital of Traditional Chinese Medicine, and Southern Hospital affiliated to Southern Medical University from June 2010 to January 2011. They were assigned to the UC group (33 cases) and the diarrhea-predominant irritable bowel syndrome (IBS-D) group (30 cases). Another 30 healthy subjects were recruited as a healthy control group. Peripheral blood mononuclear cells (PBMCs) in vitro intervened by different concentrations baicalin were taken from UC patients. IL23R gene expressions in vitro intervened by different concentrations baicalin were detected using Q-PCR. Expressions of signal transducer and activator of transcription 4 (STAT4) , STAT6, phosphorylated-STAT4 (p-STAT4), and p-STAT6 were detected using Western blot. Serum levels of IFN-γ, IL-4, IL-6, and IL-10 were measured by ELISA. Effects of different concentrations baicalin on expressions of PBMCs, and levels of IFN-γ, IL-4, IL-10 of UC patients were also detected.

RESULTSCompared with the negative control group, 40 µmol baicalin obviously decreased IL23R gene expression of UC patients (P <0. 01). Compared with the healthy control group and the IBS-D group, p-STAT4/STAT4 ratios increased, p-STAT6/STAT6 ratios decreased, levels of IFN-γ, IL-4, IL-10 all increased in the US group (all P <0. 05). Compared with the negative control, 5 and 10 µmol baicalin groups, 20 and 40 moL baicalin obviously decreased p-STAT4/STAT4 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously increased p-STAT6/STAT6 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously lowered levels of IFN-γ and IL-4, and elevated IL-10 levels (all P <0. 05).

CONCLUSION40 µmoL baicalin could in vitro inhibit p-STAT4/STAT4 ratios, adjust p-STAT6/STAT6 ratios and related cytokines, thereby balancing the immunity and relieving inflammatory reactions of UC.

Objective to explore the safety and clinical efficacy of CT-guided radioactive seed implantation in treating recurrent rectum carcinoma. Methods CT-guided ~(125)I radioactive seed implantation was carried out in 20 patients with recurrent rectal carcinoma. Treatment planning system was used preoperatively to reconstruct three dimensional image of the tumor and to calculate the estimated seed number and distribution. The tumor matched peripheral dose (MPD) of the radioactive seeds was 80-130 Gy. The radioactivity of the seeds was 0.5-0.8 mCi/seed and the median implanted seeds was 48 (range 25-95) in number. CT scan was made immediately after the implantation to check the quality of the seeds. Change of pain score, tumor size and complications were recorded during the follow-up period. Results Twenty cases composed of 12 males and 8 females, aged 38 to 78 years (median age of 62 years). The follow-up period lasted 2-28 months. On an average, 3 to 7 days after the procedure patients experienced significant pain relief. CT scan performed 2 months after the procedure revealed that complete relief (CR) of the tumor was seen in 2 cases, partial relief (PR) in 13 cases, no change (NC) in 3 cases and progression (PD) in 2 cases. The total effective rate (CR + PR) was 75%. The median survival time was 18.8 months. The survival rate of 1 and 2 years was 75% and 25% respectively. Two cases died of tumor deterioration and 3 cases died of extensive metastases. No complications such as frequent micturation, pain on urination and hematuria occurred during the follow-up period. Conclusion CT-guided ~(125)I radioactive seed implantation is a safe and effective interventional treatment for recurrent rectal carcinoma with reliable short-term efficacy and excellent anti-pain effect.

Objective To discuss the clinical efficacy of CT-guided radioactive ~(125)I seed implantation treatment for unresectable pancreatic cancer. Methods Forty patients with inoperable pancreatic cancer were enrolled in this study, including 25 males and 15 females with an median age of 69 years (38-89 years). Treatment planning system (TPS) was used to reconstruct 3-dimensional images of pancreatic tumor and to define the quantity and distribution of ~(125)I seeds. The radioactivity of ~(125)I seeds was 0.5-0.8 mCi/seed. The seeds were implanted into pancreatic tumor under CT guidance at intervals of 1 cm and were kept away from vessels, pancreatic duct and other adjacent important organs. The tumor matched peripheral dose (MPD) was 60-140 Gy. The median amount of implanted ~(125)I seeds was 36 (18-68) in number. CT scan was performed immediately after the procedure to check the quality of the seeds. In addition, 10 patients received concurrent chemotherapy with arterial infusion of gemcitabin and 5-fluororacil (5-Fu) for 3 to 4 therapeutic courses. Results The median diameter of the tumors was 4.9 cm. The follow-up period was 2 to 28 months. After the treatment the refractory pain was significantly relieved (P < 0.05), and Karnofsky score was dramatically increased (P < 0.05). Most patients experienced relief of pain within 2-5 days after implantation. Two months after treatment, on CT scans the tumors showed completed relief (CR) in 3 cases, partial relief (PR) in 20 cases, no change (NC) in 14 cases and progression (PD) in 3 cases. The overall effective rate (CR+PR) was 57.5%. The median survival time for all patients was 10.2 months, while it was 14.7 months, 10.9 months and 7.1 months for patients in stage Ⅱ, stage Ⅲ and stage IV respectively. For patients in stage Ⅱ, stage Ⅲ and stage Ⅳ, the 6-month cumulative survival rate was 100%, 88% and 62% respectively, while the 12-month cumulative survival rate was 70% , 41% and 0% respectively. After the therapy, liver metastasis occurred in 5 cases and chemoembolization was employed. In three patients, immigration of four radioactive seeds to the liver was found. No serious complications, such as upper GI bleeding, pancreatitis, pancreatic fistula formation and radiation colitis, occurred during the follow-up period. Conclusion CT-guided radioactive ~(125)I seed implantation is a safe, effective and minimally-invasive brachytherapy for unresectable pancreatic cancer with reliable short-term efficacy. It has an excellent anti-pain effect. The curative results can be further improved when chemotherapy is employed together. However, its long-term efficacy needs to be observed.

Objective To analyze the association of blood uric acid level with the severity of coronary artery stenotic changes, metabolic syndrome (MS), and its components. Methods A total of 343 individuals ( male 223,female 120) who underwent coronary angiography and had complete data on MS and serum uric acid were collected. The severity of coronary artery disease (CAD) was assessed by the coronary stenesis index (CSI). MS was diagnosed according to the Guideline on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults. Results (1)The mean uric acid level was significantly lower in women than in men [ ( 306.3±76.9 vs 358.9±85.2 ) μmol/L, P＜0.01 ]. The prevalence of MS and its components showed no difference between men and women. (2) The uric acid level in women with 3 components was higher than those with1( P＜0. 01 ) or 2 ( P＜0.05 ) components of metabolic disorders, but not in men. (3) Quartiles of concentration of uric acid were computed. Compared with those in the lowest quartile of uric acid, women in the highest quartile had higher CSI score [ 7.0 (2.5-12.0) vs 2. 0( 0.0-6.0), P= 0. 025 ]. Moreover, the uric acid level was higher in women with multivessel lesions than nonCAD patients [ (327.0±81.9 vs 284.9±78.6) μmol/L, P = 0.033 ]. However, no correlation was found between uric acid level and the severity of coronary artery lesion in men. (4) Logistic regression showed that age (β=0.042, P=0. 007) and dyslipidemia(β=0.836, P=0. 037 ) were the independent risk factors of CAD in men, and hypertension(β=1. 127, P=0.039) and dyslipidemia(β=0.901, P=0.009)in women. Conclusions In women with higher uric acid level, the clustering of metabolic abnormalities was increased, and the coronary artery lesion was more severe. High uric acid level might be a marker of CAD for women.
