Objective:To investigate the cause, treatment, and prognosis of delayed hemorrhage in patients who underwent radical gastrectomy. Methods:The clinical data of 294 patients who underwent radical gastrectomy in the Second Hospital Affiliated from Nanchang University from January 2015 to October 2015 were retrospectively analyzed. Results:A total of 15 patients suffered from delayed hemorrhage and accounted for 5.1%of the gastric cancer cases in our hospital for the same period of radical gastrectomy. Of the 15 patients, 9 underwent laparoscopic radical gastrectomy and 6 received open radical gastrectomy resection. Large vascular hemorrhage was found in 7 cases. Anastomosis and anastomotic ulcer induced hemorrhage were observed in 3 cases. Duodenal stump rupture induced hemorrhage was detected in 2 cases. Hemorrhage was also observed in some parts in 2 cases. Likewise, hemorrhage occurred in 1 case, but the affected parts were unknown. Of the 11 patients who underwent a second operation, 2 were subjected to digital subtraction angiography (DSA) and transcathete arterial embolization (TAE) to stop hemorrhage. Endoscopic hemostasis was performed to stop hemorrhage in 1 case. Conservative treatment was administered to stop hemorrhage in 1 case. The secondary surgery rate was 73.3%(11/15) with mortality and curative rates of 40%(6/15) and 60%(9/15), respectively. Conclusion:For delayed hemorrhage after D2 of gastric cancer, a second radical surgery and death rates were high. Therefore, patients suffering from hemorrhage should be subjected to comprehensive clinical treatment and positive measures. Major vascular bleeding, anastomotic leakage, anastomotic ulcer, and duodenal stump rupture are relevant risk factors. Anastomotic fistula and celiac artery bleeding complications caused hemorrhage is the leading cause of death. Extensive bleeding and unstable vital signs should be checked. A second operation and abdominal drainage should also be timely conducted to as effective methods. Realistic and conservative treatment can be administered to patients with stable vital signs and low amount of blood loss. Endoscopic hemostasis can be applied to alleviate simple anastomotic ulcer bleeding. DSA can be initially performed to detect unknown bleeding sites. TAE can be subsequently used to treat hemorrhage.

OBJECTIVETo systemically assess the feasibility and safety of complete mesocolic excision (CME) for colon cancer.

METHODSA computer-based online research of prospective, randomized or nonrandomized, controlled studies addressing CME versus traditional surgery published in the last five years was performed in electronic databases (Wanfang Database, China National Knowledge Infrastructure, Chinese Medical Current Contents, VIP, PubMed, Medline, Ovid, Elsevier, ISI Web of Knowledge, Cochrane Database of Systematic Reviews). With strictly screening according to the standard, the quality of studies was evaluated. Selective trials were analyzed by the Review Manager 5.1 software.

RESULTSA total of eight nonrandomized clinical trials, involving a total of 1209 patients (615 patients in CME group and 594 patients in control group), were identified. Meta-analysis showed that the intraoperative blood loss in CME group was less than that in control group [WMD=-13.05, 95%CI:-25.03 to -1.07, P=0.03]. No significant difference in the operation time was found [WMD=0.46, 95%CI:-26.50 to 27.41, P=0.97], and significant differences in the number of lymph node retrieved from postoperative pathologic specimens, the average length of large bowel resected, the area of mesentery resected, and the high vascular ligation were revealed between two groups. Besides there were no significant differences in the time to first flatus and the hospital stay between two groups (P=0.87, P=0.05). The postoperative complication morbidity did not increase in CME group as compared to control group (P=0.74).

CONCLUSIONCME is safe and effective in accordance with the concept of embryonic anatomy, oncological surgery and delicate surgery, and is expected to become a standardization operation method for colon cancer.

Objective To observe the effect of the method of warming kidney and dredging collaterals on the clinical effect and the content of urine C5b-9 in patients with idiopathic membranous nephropathy with spleen kidney yang deficiency and blood stasis. Methods A total of 60 idiopathic membranous nephropathy patients with spleen kidney yang deficiency and blood stasis type were randomly divided into the conventional western medicine treatment group (control group), Jingui-Shenqi pill and Taohong-Siwu decoction plus conventional western medicine treatment group (treatment group), 30 cases in each group. The Scr was detected by deproteinized alkaline picric acid method, and BUN was detected by rate method, and serum albumin (ALb) was detected by bromocresol green dye binding method, and 24 hours urinary protein was measured by pyrogallol red colorimetry, and the double antibody sandwich ELISA method was used for detection of urinary C5b-9. Results The Jingui-Shenqi pill combined with Taohong-Siwu decoction plus conventional western medicine treatment has obvious curative effect on patients. The total effective rate was 83.3 in the treatment group (25/30), and the control group was 60％ (18/30). After treatment, the Alb (33.5 ± 7.95 g/L vs. 28.8 ± 6.10 g/L, t=2.569) in the treatment groupwas significantly higher than that in the conventional treatment group (P<0.01). While the 24 h urine protein (2.40 ± 0.92 g/24 h vs.3.60 ± 2.3 g/24 h, t=2.653), the contents of C5b-9 in urine(42.5 ± 17.50 ng/mg vs.71 ± 25.2 ng/mg, t=5.088) in the treatment group were significantly lower than those in the conventional treatment group (P<0.01). Conclusions The method of warming kidney and dredging collaterals can improve the clinical symptoms, improve serum albumin level, reduce the 24 hour urine protein and urinary C5b-9 content of idiopathic membranous nephropathy of spleen and kidney yang deficiency and blood stasis type.

Objective To explore the molecular mechanism of Yishen Huoxue prescription in delaying the development of renal fibrosis by regulating the microRNA-126/vascular endothelial growth factor-Notch (miR-126/VEGF-Notch) signaling pathway. Methods Ninety male Sprague-Dawley (SD) rats were randomly divided into sham operation group (sham group), unilateral ureteral obstruction (UUO) model group, losartan group (50 mg·kg-1·d-1) and high, medium and low doses Yishen Huoxue prescription group (25.2, 12.6, 6.3 mL/kg). Each treatment group began to administer drugs by gavage on the day when UUO modeling was finished until the end of the experiment. Left renal tissues of rats were harvested after 7, 14 and 21 days postoperatively. The pathological changes of renal tissue were observed after hematoxylin and eosin (HE) and Masson staining under the microscope, and the renal fibrosis score was calculated. The mRNA expressions of renal tissues miR-126, VEGFA, vascular endothelial growth factor receptor-2 (VEGFR-2), Notch1 were detected by reverse transcription-polymerase chain reaction (RT-PCR). Results① Pathology results: the kidney tissue of sham group was normal. In UUO model group, renal tubules expanded and inflammatory cells in renal interstitium increased; renal tubulointerstitial fibrosis could be seen 7 days after operation, and the degree of fibrosis was gradually increased with time. The renal fibrosis score at each time point after operation in UUO model group was significantly higher than that in sham group. Compared with UUO model group, each treatment group were improved the degree of renal swelling and atrophy of renal parenchyma; the score of renal fibrosis were significantly decreased in the middle and high doses Yishen Huoxue prescription group and losartan group at the 7th day after operation (1.00±1.00, 0.91±0.58, 1.01±0.58 vs. 2.00±0.00,all P < 0.01); but there was no significant difference between low dose Yishen Huoxue prescription group and UUO model group. ② RT-PCR results: Compared with sham group, the mRNA expressions of miR-126, VEGFA, VEGFR-2 and Notch1 in renal tissues were significantly increased at each time point after operation in UUO model group. Compared with the UUO model group, the mRNA expressions of miR-126, VEGFA, VEGFR-2 and Notch1 in renal tissue of 7 days postoperatively in the middle and high doses Yishen Huoxue prescription group and the losartan group were significantly increased [miR-126(2-ΔΔCt):0.465±0.067, 0.639±0.092, 0.404±0.069 vs. 0.132±0.021; VEGFA(2-ΔΔCt): 0.024±0.005, 0.027±0.007, 0.023±0.006 vs. 0.014±0.006; VEGFR-2(2-ΔΔCt):0.021±0.007, 0.023±0.008, 0.019±0.007 vs. 0.012±0.004; Notch1(2-ΔΔCt):0.017±0.004, 0.020±0.005, 0.018±0.005 vs. 0.007±0.004; all P < 0.05]; compared with the losartan group, the mRNA expressions of each index in the middle and high doses Yishen Huoxue prescription group were increased at all the time points, but there was no significant difference between them (all P > 0.05). There was no significant difference in mRNA expression of each index between low dose Yishen Huoxue prescription group and UUO model group. Conclusions The medium and high doses of Yishen Huoxue prescription can effectively antagonize renal fibrosis. Yishen Huoxue prescription may use up-regulation the signaling pathways of miR-126/VEGF-Notch to mediate renal microvascular newly born, eventually to improve renal microvascular damage and delay the development of renal fibrosis progression.
