Objective To verify whether iron can accelerate the process of liver fibrosis in rats. Methods The rats were divided into control group, high fat diet group, high iron group, high fat diet and high iron group, high fat diet and de?iron group, each with 24 rats. The rats were allowed to freely take normal diet and high fat diet, while the high iron rats, high?fat diet plus high iron rats received intramuscular injection of 50 mg/kg iron dextran every other day;high?fat di?et plus de?iron group rats received tail intravenous injection of 30 mg/kg deferoxamine one month before death, 3 times/week. 8 rats were selected at 4th, 5th, 6th month of intervention, to detect serum hyaluronic Acid (HA), collagen type IV ( COL?IV) , laminin ( LN) , procollagen III ( PC III) , and observe pathological changes in the liver with Masson staining. Results At 5th month of intervention, serum HA level of the high?fat diet plus high iron group was significantly higher than those of high fat diet group and control group. At 6th month of intervention, serum COL?IV and LN levels of the high?fat diet plus high iron group were significantly higher than those of the high fat diet group. At 6th month, serum PC III level was 1. 63 time of those of the high fat diet group. At the 6th month, liver tissue of high fat diet plus high iron group ap?peared collagen deposition revealed by Masson staining, which was not the case in other groups. Conclusions Iron can accelerate high fat?induced liver fibrosis.

Objective To investigate the effect of the language intervention to reduce patients′discomfort during a colonoscopy examination. Methods A total of 72 subjects who accepted a colonoscopy process in the Digestive Endoscopy Department of the Dalian Central Hospital from September 2014 to December 2015 were divided by random number table method into two groups, 38 for the control group and 34 for the observation group. The control group adopted routine nursing care, while the observation group adopted the language intervention besides the routine nursing care, in accordance with the implementation steps of language intervention for patients who accepted the colonoscopy examination, which means the four stages , the four positions and the four methods. The first stage: the enteroscope entered the anus and arrived the rectum , applied the deep breathing with anal movement method . The second stage: from the rectum to the sigmoid colon, used the induce distraction method. The third stage: stimulated the patients′ excitement at the junctional area of descending colon and transverse colon (the spleen area). The fourth stage: at the junctional area of transverse and ascending colon (the liver ares), used the continuous excitation method. In each stage, individualized language intervention and psychological nursing were given to every patient in the observation group. The cooperating effect of the two groups were evaluated. Results The frequency of pain, the pain scores,the frequency of pressing and the average insertion time of the control group respectively were (8.68 ± 0.83) times,(45.08 ± 6.66) points, (5.73±0.75) times,(372.26±31.77) s, while the observation group were (4.53±0.38) times,(17.07± 3.01) times,(2.05±0.38) times,(268.61±14.51) s, less than the control group ,the t value respectively were 3.81,27.17,3.51,4.66, and the difference was significant (P<0.01 or 0.05). Conclusions Using the language intervention nursing method can significantly relieve the patients′ nervous and anxiety during the procedure, ease the pain and discomfort, shorten the insertion time, improve the subjects′ experience during the colonoscopy examination, make the patients more coordinate with the examination and complete it successfully.

This article established a method for the detection of tigecycline in patients with septic shock.The column was Ultimate AQ-C1s(3.0 mm × 100 mm,3 μm).The mobile phase was water (0.2% Formic acid,5 mmol/L ammonium acetate)-acetonitrile,gradient elution,the ion transitions were performed under ESI positive model at m/z 586.4→513.3 (tigecycline),m/z 338.2→296.0 (linezolid).Calibration curves of tigecycline showed good linear regression in the range of (50.15-2 006) ng/mL.The intra-day and inter-day RSD were below 15%.Plasma sample kept good stability.The cmax and AUC0-12 h of tigecycline in septic shock patients were (1.97 ±0.87) μg/mL and (9.10 ±3.58) mg.h/L.The results showed that after giving high doses tigecycline to patients with septic shock caused by multidrug-resistant strains,the AUC was not significantly higher in severe nosocomial pneumonia patients with conventional doses,and lower than the AUC of sepsis patients at the same dose,did not achieve the desired bactericidal effect.Maybe with the high hemodynamics in septic shock patients increased tigecycline glomerular filtration,and systemic infection leads to increased capillary permeability combined with interstitial edema,so that the distribution of the drug volume increases.In combination with the above,it is recommended that the recommended dose range for tigecycline in patients with septic shock caused by multidrug-resistant strains should be between 150 and 200 mg,and the concentration of tigecycline in the critically ill patients should be monitored and patients in different stages of the disease in a timely manner to adjust the dose.

OBJECTIVETo evaluate the efficacy and safety of fecal microbiota transplantation (FMT) for gastrointestinal disorders.
METHODSRetrospective analysis of the clinical data of 406 patients who underwent FMT from May 2014 to April 2016 in the Intestinal Microenvironment Treatment Centre of Nanjing General Hospital was performed, including patients with constipation(276 cases), recurrent Clostridium Difficile infection (RCDI, 61 cases), ulcerative colitis(44 cases), irritable bowel syndrome (15 cases) and Crohn's disease(10 cases). Donors were completely unrelated, 18- to 50-year-old non-pregnant healthy adult, with healthy lifestyle and habits, without taking antibiotics, probiotics and other probiotics history within 3 months. There were three routes of FMT administration: patients received 6 days of frozen FMT by nasointestinal tube placed in the proximal jejunum under gastroscope (319 cases); patients received capsules FMT per day for 6 consecutive days (46 cases) or once 600 ml of treated fecal liquid infusion into colon and terminal ileum by colonoscopy(41 cases).
RESULTSClinical cure rate and improvement rate of different diseases receiving FMT were respectively as follows: RCDI was 85.2% (52/61) and 95.1%(58/61); constipation was 40.2%(111/276) and 67.4%(186/276); ulcerative colitis was 34.1%(15/44) and 68.2% (30/44); irritable bowel syndrome was 46.7% (7/15) and 73.3% (11/15) and Crohn disease was 30.0%(3/10) and 60.0%(6/10). RCDI had the best efficacy among these diseases(P<0.01). There was no significant difference between the three routes of FMT administration(P=0.829). The clinical cure rate and improvement rate of different routes were 43.3%(138/319) and 58.6% (187/319) respectively in nasogastric transplantation group, 41.5%(17/41) and 61.0%(25/41) in colonoscopy group, 37.0%(17/46) and 63.0% (29/46) in the capsule transplantation group. There was no serious adverse event during the follow-up. The most common side effects were respiratory discomfort (27.3%, 87/319) and increased venting (51.7%, 165/319) in nasogastric transplantation group. Diarrhea was the most common complication in colonoscopy group (36.6%, 15/41). The main symptoms were increased venting (50.0%, 23/46) and nausea(34.8%, 16/46) in oral capsule group. Side effect symptoms disappeared after the withdraw of nasogastric tube, or at the end of treatment, or during hospitalization for 1-3 days.
CONCLUSIONSFMT is effective for many gastrointestinal disorders. No significant adverse event is found, while the associated mechanism should be further explored.
