Objective To investigate the distribution of pathogenic of nosocomial infections in intensive care unit (ICU) and the tendencies of its drug-resistances.Methods All of 130 patients of nosocomial infection from March 2009 to March 2013.Results Of all the nosocomial infection pathogens,gram-negative(G-) bacteria was the main(53.76％).The first five pathogens were E.coli(13.9％),E.faecalis (11.3％),A.baumannii (10.3％),S.aureus (9.8％) and K.pneumoniae (8.3％).The lower resistant to pseudomonas aeruginosa were amikacin (5.3％).A.baumannii increases rapidly and its resistances was severe.Two trains of E.faecalis were resistant to vancomycin.Conclusion G-bacteria is the main pathogens in ICU,fungal has upward tendency.The multidrug resistances of A.baumannii and E.faecalis were severe; Target monitoring is an effective surveillance method to reduce the prevalence of the nosocomial infection in ICU.

Objective To investigate the imaging features of gastrointestinal stromal tumors.Methods The clinical and imaging data of 22 patients with gastrointestinal stromal tumors(GIST)proven pathologically were retrospectively analyzed.Results Endophytic masses were displayed in 4 patients,exophytic masses in 19 patients,and exo-and endophytic masses in 3 patients.The images from the gastrointestinal radiography displayed the filling defect mass and the local mucosal fold that was pressed,pushed or even destroyed.The CT imaging showed uniform or inhomogenous tumors with calcification or necrosis and cystic changes.The enhanced CT scanning displayed different enhancements of the lesions and the enhancements were stronger in venous phase than in arterial phase.Ultrasonographical images indicated solid or cystic-solid masses with moderate-or low-level echo.Conclusion The menifestations on the images of gastrointestinal stromal tumors are helpful to diagnose the disease.

ObjectiveTo explore the deficits of acoustic startle reflex (ASR) and prepulse inhibition (PPI) of acoustic startle reflex in single prolonged stress rats.MethodsSixty Sprague Dawley rats were randomly divided into control 1,7,14 d groups and stress 1,7,14 d groups.All stressed rats received single prolonged stress while all control rats were left in their home cage.Behavioral changes in these rats were analyzed in ASR and PPI paradigm.ASR and PPI were carried out on day 2,8,15,respectively.ResultsThere were no differences of ASR and PPI among control 1,7,14 d groups (P ＞ 0.05).ASR of stress 1 d group ( (92.49 ± 31.54) g) was higher than that of control 1 d group((64.48 ± 17.95)g,P＜0.05) while PPI of stress 1 d group((28.60 ±29.02)％) was lower than that of control 1 d group( (41.60 ± 15.10)％,P ＜ 0.05 ).There were no differences of ASR between control 7 d group and stress 7 d group,control 14 d group and stress 14 d group (P＞ 0.05 ).Compared with control 7 d group ( (41.30 ± 12.79) ％ ),PPI in stress 7 d group ( ( 17.95 ± 31.79) ％ ) was reduced (P ＜ 0.05 ).Compared with control 14 d group ( (41.16 ± 12.25 ) ％ ),PPI in stress 14 d group( ( 13.71 ± 32.48) ％ ) was reduced (P ＜ 0.05).ConclusionEffects of stress on ASR in rats increased in early period,while the impaired PPI may last for a long time.

Objective To explore the nutritional status of radical gastrectomy patients during the late course of chemotherapy and its main influencing factors, providing reference for the development of targeted nursing intervention. Methods The Scored Patient-Generated Subjective Global Assessment, The Chemotherapy Side Effects of Patients with Gastric Cancer Questionnaire were used to collect clinical data that received complete chemotherapy after radical surgery from September 2014 to March 2016. Results A total of 103 cases finally involved in this study. The incidence of malnutrition in patients during pre-chemotherapy and late course of chemotherapy was 45.63%(47/103) and 73.79%(76/103) respectively, and there was significant difference (χ2=16.97, P<0.05). The nutritional assessment score, the hemoglobin levels and body mass index of patients pre-chemotherapy was (3.64±0.78) points, (124.11± 21.78) g/L, (21.29±2.77) kg/m2 , (8.07±3.75) points, (108.54±11.68) g/L, (20.29±2.68) kg/m2 late course of chemotherapy and there were significant differences(t =-11.74, 6.39, 2.63, all P<0.05). The symptom of depression was at a higher level 65.05%(67/103), patients with anorexia in late course of chemotherapy accounted as much as 75.73%(78/103). Logistic regression analysis showed that educational level, loss of appetite and parenteral nutrition were the main factors which influenced the nutritional status of patients during the late course of chemotherapy. Conclusions With the increase in the number of chemotherapy, the nutritional status of the patient is getting worse. The study suggests medical personnel should pay more attention to the patients with low educational level, give patients and their families targeted diet counseling, correct the mistaken conceptions thus enhance their understanding of dietary knowledge. Strengthening the management of complications during chemotherapy, reducing the adverse factors that affect the patient′s nutritional status to improve the nutritional status of patients.

The abdominal CT findings of cirrhosis of advanced schistosomiasis in 262 cases were analyzed.All the cases had the calcification in liver in varying degrees,hypodense structure in junction areas and blood vessel in centre,calcification in portal vein system,calcification of colon and so on.The characteristics of CT performance can provide the evidence for defferential diagnosis.

Objective To investigate the nutritional status of patients with chemotherapy after radical gastrectomy and to provide dietary guidance and nutritional support for patients in time. Methods Patients who received chamotherary after radical gastrectomy inthe Gastrointestinal Surgery of the First Affiliated Hospital of Zhengzhou University from September 2014 to March 2016 were included in the study. The nutritional status was assessed by unified training investigators within 48 h after hospitalization. The questionnaires of Scored Patient-Generated Subjective Global Assessment (PG-SGA) and the Chemotherapy Side Effects of Patients with Gastric Cancer Questionnaire were used to investigatethe patients by trained investigators. Results The scores of the nutritional status of patients with different stages of chemotherapy were 6.107 ± 2.947, 6.505 ± 3.134, 8.068 ± 3.748, which was statistically significant (F=10.202, P<0.01). The incidence of anorexia was the highest rate of diet-related symptoms, the rate of early, mid-term and later chemotherapy rates were 34.95%(36/103), 56.31%(58/103), and 75.73%(78/103) respectively. Patients acquired the diet knowledge mainly from medical staff. The proportions of early, middle and later stages of chemotherapy were 92.23% (95/103), 79.61% (82/103), 75.73%(78/103). Conclusions With the increase of chemotherapy times, the nutritional status of patients with radical gastrectomy is getting worse. The results suggested that medical staff should provide an effective basis dietary guidance in time, improving the patients′nutritional status and clinical outcomes.

ObjectiveTo investigate the effects of ziprasidone on the behavior and the expression of pERK1/2 in posttraumatic stress disorder(PTSD) model rats.Methods 24 adult male SD rats weighing (200 ±20) g were randomly divided into four groups (n =6):control group,single prolonged stress and foot shock (SPS&S) group,ziprasidone group and ziprasidone + U0126 group.The fear response to environment,high alertness,and anxiety & depression behavior of rats were tested by the open field,elevated plus-maze,and the expression of pERK1/2 was measured by Western blot.ResultsIn open field test(OFT),the SPS&S group( (76.23 ± 54.76) cm for horizontal motion distance,(4.60 ± 1.14) for the number of entering central region) showed significant difference compared with control group ( (343.77 ± 74.22 ) cm,( 12.40 ± 3.36 ) ) or ziprasidone group ( ( 274.98± 83.56) cm,( 12.00 ± 2.92) ) (P ＜ 0.01 ),but showed no significant difference with ziprasidone + U0126 group ( ( 138.14 ± 41.98) cm,(5.00 ± 1.58) ) (P ＞ 0.05 ).The results of elevated plus maze (EPM) were in accordance with the results of OFT.The expression of pERK1/2 in SPS&S group and ziprasidone + U0126 group showed significant decrease when compared with control group or ziprasidone group (P ＜ 0.01 ).ConclusionZiprasidone can obviously improve fear response to environment,high alterness and anxiety & depression behavior of rats,and these effects of ziprasidone may be carried out by up-regulation the expression of pERK1/2.

Objective To investigate the effect of quetiapine on the behavior and expression of pERK1/2 in chronic unpredictable stress(CUS) model rats.Methods 32 adult male Sprague Dawley rats were randomly divided into four groups (n =8 for each group):control group,CUS group,CUS + QUE (5 mg/kg,L) group and CUS + QUE(10 mg/kg,M)group.The rats in control group were left undisturbed in their home cage for 28 days and the other groups were exposed to 28 consecutive days of CUS,then the rats in control group and CUS group were treated with 1％ DMSO in saline (5 ml/kg,intraperitoneal injection),the rats in CUS + QUE (L)group and CUS + QUE(M) group respectively treated with quetiapine (5 mg/kg)or quetiapine(10 mg/kg) for consecutive 7 days.The weight data of each group were recorded,and the behavioral changes in these rats were analyzed by open field test and forced swimming test;and the expression of pERK1/2 was measured by Western blot.Results (1)Compared with control group,quetiapine (10 mg/kg) ameliorated the inhibition of body weight gain that induced by chronic unpredictable stress (P ＜ 0.05),but quetiapine (5 mg/kg) did not have this effect.(2)Open field and Forced swimming test showed significant difference (P ＜ 0.05) of horizontal motion distance (F =17.846),the number of central region entering(F=4.720) and the immobility time(F=26.090) in each group.And these tests showed that horizontal motion distance and the number of central region entering in CUS group ((6696.30 ±1061.19)mm,(19.63 ±9.15)times) were significantly lower than that of control group ((10824.61 ± 1399.37) mm,(37.75 ± 13.02) times) and CUS + QUE (M) group ((9637.51 ± 1630.16) mm,(32.38 ± 6.23)),while the immobility time (110.73 ± 15.98)s were significantly higher than that of control group((66.13 ± 5.18)s)and CUS + QUE (M) group((73.40 ± 11.99) s,P ＜ 0.05).But there was no significant difference between that of CUS group and CUS + QUE(L) group(P＞0.05).(3)The expression of pERK1/2 in CUS group showed significant decrease when compared with control group or CUS + QUE (M) group,but showed no significant difference with CUS + QUE(L) group(F=6.641,P＜ 0.01).Conclusion Quetiapine can ameliorate depressive-like behaviors induced by chronic unpredictable stress,and this effect may be carried out by up-regulation the expression of pERK1/2 in the hippocampus.

Objective To discuss the treatment of urethral stricture after hypospadias reDair.Methods Thirty-seven cases of urethral stricture after hypospadias repair from 1999 to 2006 were ret-rospectively analyzed. Of 37 patients,the stricture was located at the distal end of urethra in 7 cases.There were 3 1 cases with anastomotic stricture.There was 1 case with distal urethral stricture and anastomotic structure.There were 1 3 patients with the simple urethral stricture and the complicated 24 cases.Of 13 simple urethral stricture patients,4 patients were repaired with urethro-meatomy,6 patients with shelf operation and 3 patients with transurethral holmium laser urethrotomy.Eight Pa-tients with complicated urethral fistula,6 patients with urethral diverticula,4 patients with phallo-campsis and 6 patients with many times of postoperative urethral stricture were repaired with shelf op-eration or penis skin flap or septum of scrotum skin flaps urethroplasty. Results The simple stric-tures of 1 2 patients were cured by stage 1 operation,the other one cured after second surgery.Of 8 patients with fistula,7 were cured at stage 1,the other one was cured at the stage 2.Of 6 patients with diverticulum,all were cured at stage 1.Of 4 patients with phallocampsis,3 cases were cured at stage 1,the other one was cured at the stage 2.Of 6 patients with recurrent strictures,all were cured at stage 1.A1l patients were followed up 1 2 to 24 months.The micturition was without difficuItv at stand position. Conclusions Urethral stricture is one of the most common complications after hypos-padias repair.The simple urethral stricture could be repaired with urethro-meatomy or sheIf operation or transurethral holmium laser urethrotomy.The complicated urethral stricture could be reDaired with shelf operation or penis skin flaps or septum of scrotum skin flaps urethroplasty and overjetted with dortos of scrotum flaps.
