Objective:To investigate the perceptions of ICU patients on nurse caring behaviors and related factors,then raise nursing straties. Methods:101 ICU patient samples were selected from two tertiary general hospital(sGrdae A)in Fuzhou.The mod- ified caring behavior assessmen(tCBA)scale was used to interview the subjects. Results:The most important caring behaviors were to help patients satisfy their basical requiments. There were statistically significant differences in the perceptions of importance of nurse caring behaviors among the patients’demographic data such as marriage and length stayed in ICU.Conclusion:ICU patients need nurse caring behaviors. Nurses should provide patients with individual caring behaviors to satisfy their requi-ments. So nursing quality and patient satisfaction would be improved.

The binding capacity (R_o) and apparant dissociation constant (K_d) of glucocrticoid binding sites in hepatic cytosol of normal and scalded rats were measured by pseudoscatchard analysis. Compared with control group, the levels of Ro of glucocorticoid receptor was significantly decreased 1 h after scalding, partialy recovered at 12h after scalding and fully recovered at 24 h after scalding. The levels of low-affinity glucocorticoid binding sites were also decreased 12 h after scalding, but had no statistical significance. The possible significance of these results has been discussed.

Objective To investigate the clinical characteristics of upper gastrointestinal diseases in very old people (aged ≥ 90 years),and to explore the necessity and safety of the gastroscopy for the super elderly people.Methods Clinical data of 50 very old people were retrospectively analyzed.Results The total detection rate of upper gastrointestinal disease was 76.0％ (38/50),in which the reflux esophagitis (RE) was the most common (26.0％),followed by erosive gastritis (20.0％),atrophic gastritis (18.0 ％),peptic ulcer (12.0 ％),gastrointestinal cancer (10.0％),duodenitis (8.0％) and fundic gland polyps (6.0％) respectively.RE lesions detected by gastroscopy were mainly mild and were divided into endoscopic grade LA-A (46.1％),LA-B (30.8％),LA C (7.7％),and LA-D (15.4％) according to the Los Angeles classification.The most common symptoms were abdominal distension and anorexia,and the both incidences were 12.0％.There was no significant difference in the prevalence of clinical symptoms between the elderly people with upper gastrointestinal disease and without abnormal gastroscopic findings [44.7％ (17/38) vs.41.7％ (5/12),x2 =0.035,P＞0.05].22 patients (44.0％) underwent gastroscopy under intravenous anesthesia.Conclusions The incidence of upper gastrointestinal disease is high in very old people,and mild reflux esophagitis is the most common.Clinical symptoms are little or asymptomatic in most very old people.Gastroscopy under intravenous anesthesia is safe and feasible for the very old people.

Objective To evaluate the clinical efficacy of endoscopic esophageal variceal ligation (EVL) for esophageal variceal bleeding (EVB) in elderly patients with hepatic cirrhosis.Methods From July 2007 to July 2013,clinical data of 198 patients who had been diagnosed with liver cirrhosis presenting with EVB were retrospectively analyzed.Among them,167 patients who had received EVL were divided into the elderly EVL group (n=97,age≥60 years) and the non-elderly EVL group (n=70,aged ＜ 60 years).The other 31 cases (aged ≥ 60 years) had received propranolol therapy.Treatment effectiveness,adverse effects,complications and the one-year survival rate of each group were analyzed.Results The efficacy rates and variceal recurrences were 77.3％ (75/97) and 78.6％ (55/70) in the elderly EVL group and 19.6％ (19/97) and 18.6％ (13/70) in the non-elderly EVL group,respectively,with no significant difference between the two groups (each P＞0.05).The re-bleeding rate was higher in the propranolol treatment group than in the elderly and non-elderly EVL groups [58.1％ (18/31) vs.24.7％ (24/97) vs,22.9％ (16/70),x2 =14.76,P =0.00].One-year survival rates in the elderly group,the non-elderly EVL group and the propranolol treatment group were 86.6 (84/97),88.6％ (62/70),64.5％ (20/31),respectively,with statistically significant differences between the three groups (x2 =10.24,P=0.01).Conclusions EVL is effective for the treatment of hepatic cirrhosis with EVB and can be used as a secondary prophylaxis measure for EVB in elderly patients with hepatic cirrhosis.

BACKGROUND:Proteoglycan, chondroitin sulfate and keratan sulfate, and hyaluronic acid are important substances in the maintenance of intervertebral discs of normal structure. They impact the physiological function of intervertebral disc.
OBJECTIVE:To observe the influence of Liuwei Dihuang Wan on proteoglycan in rabbit models of intervertebral disc degeneration, and to study the efficacy of Liuwei Dihuang Wan on prevention and treatment of intervertebral disc degeneration.
METHODS:80 New Zealand rabbits were randomly divided into Liuwei Dihuang Wan group, model group, sham surgery group and blank control group (n=20 per group). Animal models of intervertebral disc degeneration were established in the model and Liuwei Dihuang Wan groups. In the sham surgery group, surgery via the same approach to expose the lumbar spine was conducted fol owed by layer-by-layer suturing. In the Liuwei Dihuang Wan group, rabbits were given 10 mg/kg Liuwei Dihuang Wan by lavage, once a day. In the model group, sham surgery group and blank control group, rabbits were given an equal volume of physiological saline, once a day, by natural feeding. At 2, 4, 6 and 8 weeks, five rabbits from each group were sacrificed, and intervertebral disc specimens were taken to measure proteoglycan components in the intervertebral disc.
RESULTS AND CONCLUSION:With the extension of feeding time, Liuwei Dihuang Wan could increase sugar amino polysaccharide content, chondroitin sulfate/acid ratio of keratin, and hyaluronic acid content in the intervertebral disc degeneration model, and stabilized the proteoglycan content. Thus, it delayed the degeneration of the intervertebral disc to a certain extent.

Objective To compare the differences in the efficacy of Bifidobacterium tetravaccine tablets.Bifidobacterium triple viable capsules and live Bacillus licheniformis capsule in the treatment of persistent and chronic diarrhea.Methods From September 2015 to June 2016,a total of 484 outpatients with persistent and chronic diarrhea were enrolled and divided into observation group (treated with Bifidobacterium tetravaccine tablets) and control group (treated with the combination of Bifidobacterium triple viable capsules and live Bacillus licheniformis capsule).Before and after treatment,the frequency of defecation and the characters of stool were observed and the differences in the treatment efficacy in persistent and chronic diarrhea between two groups were compared.Paired t test and Chi square test were used to compare the difference before and after treatment in each group,and independent sample t test was used for comparison between groups.Results There were a total of 256 patients in the observation group (four cases lost and 256 cases were completed).Meanwhile there were 228 patients in the control group (30 cases lost and 228 cases completed).In the observation group,after treatment the frequency of defecation was (2.13±1.06) times,which was less than that before treatment ((3.83±0.95) times),and the difference was statistically significant (t=29.149,P＜0.01).In the control group,after treatment the frequency of defecation was (2.19 ± 1.06) times,which was less than that before treatment ((3.87 ±0.98) times),and the difference was statistically significant(t =27.800,P＜0.01).There was no statistically significant difference in the frequency of defecation before and after treatment between two groups (t=-0.460 and-0.662,both P＞0.05).Furthermore there was also no statistically significant difference in the rate of normal bowel movements between observation group and treatment group after treatment (50.8％(130/256) vs 57.9％(132/228;x2=2.458,P=0.117).There was no significant difference in effective rate (64.8％(166/256) vs 69.7％ (159/228) and excellence rate (47.7％ (122/256) vs 51.3％ (117/228)) between two groups (P=0.253 and 0.422);besides,no severe adverse events were reported.Conclusion In the aspect of improving of times of defecation and characters of stool in patients with persistent and chronic diarrhea,single medication of multi bacteria strains Bifidobacterium tetravaccine tablets has the same satisfied efficacy and good safety as the combination of Bifidobacterium triple viable capsules and live Bacillus licheniformis capsule.

Aim To observe the fluctuation of uric acid in serum after replicating rat hyperuricemia model with hypoxanthine、uricase inhibitor combined,and to discuss the method of continuity hyperuricemia replication on rats. Method Hypoxanthine was administered via stomach or bait vessel,uricase inhibitor was injected subcutaneouslly,then the relative biochemical indicators of rats were inspected respectively at different periods of time after replicating the model. Results When hypoxanthine(50 g HX?kg-1bait vessel or 100 g HX?kg-1bait vessel) was administered via bait vessel,uricase inhibitor(200mg?kg-1) was injected subcutaneouslly,the uric acid in serum of different groups were much higher than control group(P

Objective To evaluate the safety of conscious venous anesthesia with fentanyl and propofol in elderly patients over 70 during gastrointestinal endoscopy. Methods Clinical data of 826 elderly patients over 70, who underwent gastrointestinal endoscopy with venous anesthesia, were retrospectively analyzed. The patients were divided into 2 groups according to their ages, with 618 patients aging from 70 to 80 in group A, in which 342 received endoscopy and 276 underwent colonoscopy, and 208 patients older than 80 in group B, in which 112 underwent endoscopy and 96 had colonoscopy. Another cohort of 600 patients younger than 70, who underwent venous anesthetic endoscopy during the same time period, was randomly selected as the control group, in which 400 patients received endoscopy and 200 had colonoscopy. Blood pressure, heart rate, peripheral oxygen saturation (SpO2) and adverse reaction were monitored in each patient during the procedure and compared among different groups. Results No procedure-related perforation or sedation-related mortality was observed, and no procedure was terminated clue to sedation complication. The average dosages of propofol used in procedure of endoscopy in groups A, B and control were 54.22±21.36 mg, 40.22±12.46 mg, and 86.44±34.26 mg, respectively. The average dosages of propofol in colonoscopy were 82.56±40.64 mg, 45.36±15.44 mg and 102.23±46.32 mg, respectively. With same procedure, there was no significant difference in heart rate and blood pressure among different groups, nor was there any difference in these variables before and after the procedure in each group (P>0.05). Sedation exerted more influence on SpO<,2> in elderly patients. A total of 18 cases in groups A and B experienced SpO<,2> <90%, which was mainly due to aspiration of saliva and relieved by oxygen inhalation. Conclusion Under appropriate monitor, it is safe and feasible to give conscious sedation to elderly patients over 70 during gastroimestinal endoscopy.

Objective To analyze the clinical characteristics of gastric polyps in different histopathological types. Methods Based on histopathological difference, gastric polyps were categorized into fundic gland polyps, hyperplastic polyps, inflammatory polyps, adenomatous polyps, etc; Different types of polyps in the aspects of distribution, Helicobacter pylori (H. pylori) infection, the relationship between the proton pump inhibitors (PPI) and the occurrence of gastric polyps to provide guidance on treatment Results 365 cases of gastric polyps were diagnosed in 10 197 patients who underwent gastroscopy. The prevalence was 3. 6%. The histopathological type of the polyps were fundic gland polyps (61. 1%), hyperplastic polyps (23. 3%) , inflammatory polyps (12. 3%) , adenomatous polyps (2. 2%). 289 cases showed single polyps, which was the majoriry across all types of gastric polyps. Majority of the gastric polyps were located in gastric body and fundus, followed by gastric antrum and cardia Most of the fundic gland polyps were located in gastric body and fundus; Majority of the hyperplastic polyps and adenomatous polyps were located in gastric antrum; The main locations of inflammatory polyps were cardia and gastric body and fundus. A higher percent (51. 6%) of fundic gland polyps patients used PPI. The difference was statistically significant compared with the hyperplastic polyps(8. 2%)and inflammatory polyps group(8.9%) (x2 = 48. 31,27. 63 ,P <0. 01). The H. pylori infection rate of hyperplastic polyps and inflammatory polyps were 72.4% and 74.4% ,respectively, both of which were higher than that of fundic gland polyps(20. 2%)(x2 =46. 50,35. 04, P < 0. 01) . One year after the H. pylori eradication, the recurrence cases of hyperplastic polyps and inflammatory polyps were 1/41 and 0/19,respectively. Conclusions The main histopathological type of gastric polyps is fundic gland polyps followed by hyperplastic polyps. The main location of the gastric polyps is gastric body and fundus, followed by gastric antrum and cardia. The distribution of different types of gastric polyps has some characteristics. Long-time usage of PPI may increase the risk of fundic gland polyps. The occurrence of hyperplastic polyps and inflammatory polyps may be related to H. pylori infection. The H. pylori eradication helps preventing the recurrence of hyperplastic and inflammatory gastric polyps.
