Objective To study the screening value of color doppler flow imaging (CDFI) for gastroesophageal reflux(GER).Methods Through the window of left lobe liver, the abdominal esophageal length,the phenomenon of GER and the frequency of GER were detected by CDFI in 55 children with GER and 55 control group.Results Abdominal esophagus was identified by CDFI in every children. The abdominal esophageal length was shorter in refluxers than that in control group. A significant correlation was found between its length and the age of control group.To diagnose GER with CDFI ,its accuracy was 98.18%,and its specificity was 76.36%.Conclusions Visualization and measurements of the abdominal esophagus are readily achieved with CDFI in children.Abdominal esophageal length is shorter in refluxers than that in control group. CDFI is a rapid method of screening GER.

Objective To study whether gastric liquid emptying is delayed in children with gastroesophageal reflux and its clinical significance. Methods At different times after meal, the gastric antral diameters were measured by real - time ultrasonography in 55 children with gastroesophageal reflux and 55 controls. Results At 20 min,60 min after meal , there was a significant difference in gastric emptying rate between case groups and control groups, respectively(P

Early enteral nutrition is more compatible with physiological status,is beneficial to cell and organ function recovery and helpful to reduce the incidence of infection and to improve the prognosis.However,due to facts like intra-abdominal hypertension,hemodynamic instability,intestinal dysfunction,early enteral nutrition is usually difficult to successfully implemented in surgical critically ill patients.This paper reviews the progress of early enteral nutrition implementation in surgical ritically ill patients.

Objective To investigate the prevalence rate of healthcare-associated infection(HAI)in a hospital,so as to provide reference for making HAI control measures.Methods The cross-sectional survey on HAI was carried out among all hospitalized patients on May 26,2010,December 12,2012 and December 4,2013,respectively,sur-veyed data were analyzed.Results The prevalence rate was 6.66%(n =116),6.67%(n =113)and 6.33%(n =120)in 2010,2012 and 2013 respectively,and case rate was 7.29%(n=127),7.38%(n=125)and 6.97%(n=132) respectively,intensive care unit(ICU )had the highest infection rate,internal medicine ICU was up to 71 .43%. The main infection site was lower respiratory tract(44.53%),followed by surgical site infection (9.11 %)and uri-nary tract infection (9.11 %).The isolation rate of gram-negative bacteria,gram-positive bacteria and fungi was 60.81 %,20.38% and 18.81 % respectively.Usage rate of antimicrobial agents in three years was 32.95%, 29.87% and 25.59% respectively (χ2 = 13.16,P <0.01 ).Conclusion Prevalence rate of HAI in this hospital is high ,the main pathogen is gram-negative bacteria,the main infection site is lower respiratory tract ,antimicrobial use decreased year by year.Monitor on high risk departments,main sites and pathogens should be intensified.

To perform a systemic review and meta-analysis of the diagnostic accuracy of PET (CT) and metaiodobenzylguanidine (MIBG) for diagnosing neuroblastoma (NB),electronic databases were searched as well as relevant references and conference proceedings.The diagnostic accuracy of MIBG and PET (CT) was calculated for NB,primary NB,and relapse/metastasis of NB based on their sensitivity,specificity,and area under the summary receiver operating characteristic curve (AUSROC) in terms of per-lesion and per-patient data.A total of 40 eligible studies comprising 1134 patients with 939 NB lesions were considered for the meta-analysis.For the staging of NB,the per-lesion AUSROC value of MIBG was lower than that of PET (CT) [0.8064±0.0414 vs.0.9366±0.0166 (P＜0.05)].The per-patient AUSROC value of MIBG and PET (CT) for the diagnosis of NB was 0.8771±0.0230 and 0.6851±0.2111,respectively.The summary sensitivity for MIBG and PET (CT) was 0.79 and 0.89,respectively.The summary specificity for MIBG and PET (CT) was 0.84 and 0.71,respectively.PET (CT) showed higher per-lesion accuracy than MIBG and might be the preferred modality for the staging of NB.On the other hand,MIBG has a comparable diagnosing performance with PET (CT) in per-patient analysis but shows a better specificity.

OBJECTIVETo observe the impacts on the muscle strength in the patients of stroke-induced acroparalysis treated with Xunjingcuiqi needling technique.

METHODSOne hundred patients were randomized into a Xunjingcuiqi group and a routine acupuncture group, 50 cases in each group. In the routine acupuncture group, the routine acupuncture technique was adopted at the main acupoints, such as Shangxing (GV 23), Baihui (GV 20), Dicang (ST 4), Quchi (LI 11), Huantiao (GB 30) and Zusanli (ST 36), etc. In Xunjingcuiqi group, on the basis of the routine acupuncture technique, Xunjingcuiqi needling technique (pricking technique was quickly applied with the filiform needle along the running course of meridian to promote the conduction of meridian qi) was added. For the patients being hard to feel the needling sensation and with the muscle strength of 0 to 1 degree, Dongzhencuiqi technique was supplemented at shu-stream points of yang meridians (after qi arrival, the needling manipulation with limb movement was given to promote the conduction of meridian qi). The treatment was given once every day in the two groups. Ten treatments made one session. Three sessions of treatment were required. At the end of each session treatment, the muscle strength and clinical efficacy were assessed.

RESULTSIn the 1st, 2nd and 3rd sessions of treatment, 20, 24 and 36 cases achieved the 3 to 5 degrees muscle strength in Xunjingcuiqi group, respectively; and 6, 10 and 15 cases achieved the 3 to 5 degrees muscle strength in the routine acupuncture group. The differences were significant statistically in comparison of the two groups (P < 0.01, P < 0.05). The markably effective rates were 60.0% (30/50), 64.0% (32/50) and 70.0% (35/50) after the 1st, 2nd and 3rd sessions of treatment in Xunjingcuiqi group, respectively; and those were 38.0% (19/50), 44.0% (22/50) and 46.0% (23/50) in the routine acupuncture group, respectively. The differences were significant in the 1st and 3rd sessions of treatment between the two groups (both P < 0.05).

CONCLUSIONXunjingcuiqi needling technique combined with routine acupuncture achieves the apparent superior efficacy on acroparalysis induced by ischemic stroke as compared with the simple routine acupuncture. Xunjingcuiqi needling technique obviously improves muscle strength and shortens the duration of sickness.

Objective To study the effect of chest wall vibration therapy on bronchiolitis. Methods A total of 64 patients with bronchiolitis were divided into an experimental group and a control group, the former included 34 cases and the latter included 30 cases. The experimental group received both routine treatment and chest wall vi- bration, while the control group only received routine treatment. PaO_2, PaCO_2, SaO_2, Heart Rate (HR) and Respi- ration (R) were observed, respectively, in the experimental group and the control group at the beginning and the end of the third day. Time needed for expectoration and length of hospital stay in the two groups were observed. Results It was shown that PaO_2, PaCO_2, SaO_2 , HR, R were significantly improved at the end of the third day when compared with those at the beginning in both groups(P

Objective To retrospectively analyze the prognostic factors for locoregionally recurrent early?stage extranodal nasal?type natural killer/T?cell lymphoma ( NKTCL) . Methods A total of 56 patients with early?stage extranodal nasal?type NKTCL, who had locoregional recurrence after initial treatment and then received salvage treatment from 1995 to 2014, were enrolled as subjects. The effects of salvage treatment on the overall survival ( OS) rate were analyzed after initial treatment and recurrence. Univariate and multivariate prognostic analyses were performed on the OS rate after recurrence. Results The median follow?up time was 35. 9 months after initial treatment and 14. 8 months after recurrence. The 3?year OS rate was 73% after initial treatment and 58% after recurrence. Compared with chemotherapy alone, radiotherapy?containing salvage treatment significantly improved the OS rates after initial treatment and recurrence ( P=0. 040, 0. 009 ) , and re?irradiation also significantly improved the OS rates after initial treatment and recurrence (P=0. 018, 0. 019). Most (84%) of the acute and late adverse reactions after re?irradiation were grade 1?2 ones. The univariate and multivariate analyses showed that the Karnofsky Performance Status score, radiotherapy in initial treatment, and radiotherapy in salvage treatment were influencing factors for the OS rate after recurrence. Conclusions Radiotherapy achieves improved survival and tolerable toxicities, making it indispensable in the treatment of locoregionally recurrent extranodal nasal?type NKTCL.
