OBJECTIVETo study the correlation between arachidonic acid (AA) and acute red blood cells damage in rats, and to build a model with hidden blood loss in vivo, and to explore the pathological mechenism of hidden blood loss.

METHODSA total of 50 male adult Sprague-Dawley rats weighing (200 ± 20) g were randomly divided into five groups (n = 10): control group and four experimental groups. The rats in the experimental groups were given 0.5 ml different concentrations of AA dilu- ents, 5, 10, 20, 40 mmol/L respectively. The blood samples were collected from orbital venous at the beginning and 24, 48, 72 hours after administration. Then the changes of hemoglobin (Hb) ,red blood cell count (RBC), glutathione peroxidase (GSH- PX) activity, total superoxide dismutase (T-SOD) activity and hydrogen peroxide (H202) in the blood samples were tested.

RESULTSSignificant hidden blood loss occurred when the concentration was 10 mmol/L in the experimental group, with the RBC and Hb sharply reduced in blood samples. The Hb and RBC were reduced in all the experimental groups and control group at 24 hours after administration, while in the experimental groups they changed more obviously. The GSH-PX activity, T-SOD activity and H₂O₂were also significantly reduced in all groups, and the changes showed significant differences. The Hb and RBC were relatively stable in the control group and the experimental groups at 48 hours after administration; while GSH-PX activity, T-SOD activity and H₂O₂were all significantly decreased, and the changes in the experimental groups were more notable.

CONCLUSIONElevated levels of AA in the blood causes oxidative stress in the red blood cells, leading to the damage of red blood cells and hemoglobin, which is responsible for hidden blood loss.

Objective To investigate the mechanism of fluoroquinolone resistance in clinical isolates of Enterococcus faecium. Methods The MICs of six fluoroquinolones(norfloxacin,ciprofloxacin,ofloxacin,levofloxacin,gatifloxacin and moxifloxacin) against 35 clinical isolates of E.faecium from eight hospitals in Tianjin were determined by agar dilution method in the absence or presence of multidrug resistance efflux pump inhibitor reserpine.The quinolone-resistance determining region(QRDR)of parC and gyrA were amplified and sequenced.Results No less than twofold decrease in MIC values of the six fluoroquinolones in the presence of reserpine was observed in 35,29,1,0,6 and 2 of the 35 strains of E.faecium respectively.One fluoro- quinolone-susceptible isolate and five fluoroquinolone-resistant isolates were selected randomly to analyze the QRDR of parC and gyrA.All five fluoroquinolone-resistant isolates had single amino acid alteration in both GyrA and ParC.Ser-80 in ParC was substituted by lie(4 isolates)or Arg(1 isolates).Glu-87 in GyrA was replaced by Lys(2 isolates)or Gly(2 isolates). The other one had an Ser-83-to-Ile substitution.The one fluoroquinolone-suseeptible isolate had no alteration in the QRDR of either ParC or GyrA.Conclusions Both target alteration and active efflux are responsible for the resistance to fluoroquinolone in clinical isolates of E.faecium.

BACKGROUND/AIMS: Irritable bowel syndrome (IBS) is a common disease characterized by intestinal dysmotility, the mechanism of which remains elusive. We aim to determine whether the high-affinity choline transporter 1 (CHT1), a determinant of cholinergic signaling capacity, modulates intestinal motility associated with stress-induced IBS. METHODS: A rat IBS model was established using chronic water avoidance stress (WAS). Colonic pathological alterations were evaluated histologically and intestinal motility was assessed by intestinal transit time and fecal water content (FWC). Visceral sensitivity was determined by visceromotor response to colorectal distension. RT-PCR, western blotting, and immunostaining were performed to identify colonic CHT1 expression. Contractility of colonic muscle strips was measured using isometric transducers. enzyme-linked immunosorbent assay was used to measure acetylcholine (ACh). We examined the effects of MKC-231, a choline uptake enhancer, on colonic motility. RESULTS: After 10 days of WAS, intestinal transit time was decreased and fecal water content increased. Visceromotor response magnitude in WAS rats in response to colorectal distension was significantly enhanced. Protein and mRNA CHT1 levels in the colon were markedly elevated after WAS. The density of CHT1-positive intramuscular interstitial cells of Cajal and myenteric plexus neurons in WAS rats was higher than in controls. Ammonium pyrrolidine dithiocarbamate partly reversed CHT1 upregulation and alleviated colonic hypermotility in WAS rats. Pharmacological enhancement of CHT1 activity by MKC-231 enhanced colonic motility in control rats via upregulation of CHT1 and elevation of ACh production. CONCLUSION: Upregulation of CHT1 in intramuscular interstitial cells of Cajal and myenteric plexus neurons is implicated in chronic stress-induced colonic hypermotility by modulation of ACh synthesis via nuclear factor-kappa B signaling.

OBJECTIVETo explore whether there exists coincidence of the most appearing time of clinical features of liver cancer at different longitude and latitude, according to the law of field equation and the theory of warpage of space time by Einstein.

METHODSThree regions with different longitude and latitude were selected randomly and sampled. There were 36 items altogether, including 12 clinical items, which were used to imitate the yearly cycle cosine curve. The acorphases and the ratioes of amplitudes and means were compared to justifying whether they were in the same range.

RESULTSAll the acorphases of 36 items appeared between -90.1degrees to -207.5 degrees (from april to july), existing in one third of the same range, in which 13 items occurred rhythmly (P<0.05). The image acorphases of liver cancer at the early and middle stage and gamma-glutamyl transpeptidase acorphase appeared between -98.5 degrees to -148.2 degrees (from april to may), in which 5 items occurred rhythmly (P<0.05).

CONCLUSIONIt is the same mode of the yearly biologcal cycle for liver cancer malignant growth within the most appearing time (from april to july). It will increase the detecting rate of liver cancer at the early and middle stage during this time (especially from april to may).

Objective: To investigate the effect of end-to-side pancreaticojejunostomy with pocket-insertion on the incidence of pancreatic fistula after pancreaticoduodenectomy. Methods: The clinical data of 581 patients undergoing pancreaticoduodenectomy from Dec. 2012 to Sep. 2018 in Cangzhou Central Hospital were retrospectively analyzed, including 327 cases of open pancreaticoduodenectomy (OPD) , 175 cases of laparoscopic assisted pancreaticoduodenectomy (LAPD) , and 79 cases of total laparoscopic pancreaticoduodenectomy. End-to-side pancreaticojejunostomy with pocket-insertion was used in all cases. The incidence of pancreatic fistula after operation was analyzed. Results: The overall incidence of grade B or C pancreatic fistula was 3.10% (18/581) after end-to-side pancreaticojejunostomy with purse-pocket insertion. The incidence of grade B or C pancreatic fistula in OPD group was 2.75% (9/327) . The incidence of grade B or C pancreatic fistula in LAPD group was 2.29% (4/175) . The incidence of grade B or C pancreatic fistula in TLPD group was 6.33% (5/79) . The three groups were divided into two subgroups according to the pancreatic texture. There was significant difference in pancreatic duct diameter between subgroups (P<0.05) , but there was no significant difference in the time of pancreaticojejunostomy and the incidence of pancreatic fistula after operation (P>0.05) . Conclusion End-to-side pancreaticojejunostomy with pocket insertion has the advantages of simple operation, strong adaptability, safety and high efficiency, and can control the incidence of pancreatic fistula after pancreaticoduodenectomy at an ideal level.

Objective To investigate the choice of surgical methods and short-term therapeutic efficacy of laparoscopic pancreaticoduodenectomy.Methods A retrospective analysis was performed on the clinical data of 188 cases who underwent laparoscopic pancreaticoduodenectomy (LPD) from December 2015 to December 2017 in Cangzhou Central Hospital.Total laparoscopic pancreaticoduodenectomy (TLPD) was performed in 102 patients whose diameter of pancreatic duct was greater than or equal to 3 mm,and end-to-side anastomosis of pancreatic duct and jejunum was used to reconstruct the digestive tract (TLPD group).Laparoscopic assisted pancreaticoduodenectomy (LAPD) was performed in 86 patients with pancreatic duct diameter less than 3 mm,and the digestive tract was reconstructed by end-to-side pancreaticoduodenectomy with pocket-insertion (LAPD group).The clinical data of the two groups were analyzed and compared.Results There were no significant differences on sex,age,ASA grade,preoperative total bilirubin,alanine aminotransferase and serum albumin levels between the two groups(P ＞0.05),which was comparable.The total incision length and hospitalization time in TLPD group were significantly shorter than those in LAPD group [(8.2± 1.4)cm vs (12.9±2.6) cm];[(10.9±5.9)d vs (14.3±6.5) d],while the time of pancreaticojejunostomy was significantly longer than that in LAPD group [(36.1 ± 14.7) min vs (14.0 ± 4.2) min].The incidence of pancreatic fistula after operation was significantly higher than that in LAPD group (30.4％ vs 10.5％).The difference was statistically significant (all P＜0.05).There were no significant differences on mean operation time,intraoperative bleeding volume,number of lymph node dissection,R0 resection rate,ICU admission time,eating time,total complication rate and 6-month disease-free survival rate between the two groups.Conclusions TLPD has the advantages of less trauma and quicker recovery.But for pancreatic duct diameter less than 3 mm,the choice of LAPD can increase the safety of operation and reduce the incidence of postoperative pancreatic fistula.
