Objective To investigate the effects of sepsis bundles in China.Method An observational study of 43 patients with severe pneumonia and septic shock admitted to the respiratory intertive care unit(1/11/2006-31/12/2007)was carried out.The selection criteria were in accordance with criteria set by International Conference On Sepsis in 2001.Implementation of 6 hours and 24 hours sepsis bundles was divided into 3 continu-ous phases consisting of education,trial,and application phase.A cohort of 43 patients with matched disease his-tory(1/1/2004-31/10/2006)was enrolled as control group.The percentages for categorical variables and mean±SD for continuous variables were reported.Chi-Square test.unpaired Student's t -test.paired-samples t test,univariate and multivariate logistic regression models were used.Statistical significance was defined as P＜0.05.Results There were very little significant differences in basic characteristics of patients between the two groups.Compared with control group,the differences in serrum lactate,fluid resuscitation and fluid volume infused within 6 hours and blood glucose control in shock subgroup were significant(P values were 0.024,0.009,0.045,and 0.000,respectively).Compared with control group,the differences in respiratory rate and oxygenation index of bundles group at 72 hours later were significant(P values were 0.033 and 0.041,respectively).Compared with control group,the differences in APACHE Ⅱ score and predicted mortality in shock subgroup of bundles were sig-nificant(P values were 0.017 and 0.040,respectively).Compared with control group,the reduction in absolute mortality was 23.30% in bundles group(P=0.019).Conclusions Implementation of sepsis bundles con-tributes noticeably to the significant reduction in mortality of patients with severe pneumonia and septic shock.

Objective To evaluate the effects of 0.0％ and 0.02％ atropine on pupil diameter (PD) and accommodation amplitude (AMP) in myopic children and analyze its relation factors.Methods A prospective randomized controlled trial design was adopted.One hundred and ninety-three myopia children were included from June to October,2016 in the First Affiliated Hospital of Zhengzhou University,all the children completed one-year follow-up.All the children were divided into three groups randomly,with 72,74 and 80 myopic children in 0.01％ atropine group,0.02％ atropine group and control group,respectively.The myopic children in 0.01％ atropine group and 0.02％ atropine group wore single-vision spectacle lenses and were treated with 0.01％ and 0.02％ atropine eye drops nightly,respectively.The myopic children in the control group wore spectacle lenses only.The PD and AMP were measured at baseline,and 4,8 and 12 months after treatment.Results There were no significant difference of baselinePD and AMP among the three groups (F=9.321,P=0.820;F=13.209,P=0.220).Compared with basline,after 12 months,the PD increased by 0.75,0.84 and 0.02 mm in 0.01％ atropine group,0.02％ atropine group and control group,respectively.There were statistically significant differences of PD among three groups at different time points (Fgroup =2.168,P=0.013;Ftime =2.139,P=0.015;Finteraction =2.148,P=0.001).Compared with baseline,the PD of 0.01％ atropine group and 0.02％ atropine group were increased 4,8 and 12 months after treatment,and the difference was statistically significant (all at P＜0.001).The PD was stable in control group.After 12 months,the AMP were reduced by 1.25,1.12 and 0.28 D in 0.01％ atropine group,0.02％ atropine group and control group,respectively.There were statistically significant differences of AMP among the three groups at the different time points (Fgroup =18.346,P =0.034;Ftime =1.823,P =0.002;Fintercation =3.239,P =0.023).Compared with baseline,the AMP of 0.01％ atropine group and 0.02％ atropine group were increased 4,8 and 12 months after treatment,and the differences were statistically significant (all at P＜0.05).The AMP remained stable in control group.The change of PD in 0.01％ atropine group and 0.02％ atropine group was correlated with age,baseline PD and baseline eye axis length,respectively (β =0.060,P =0.019;β =-0.440,P＜0.001;β =-0.37,P =0.045).The change in AMP of the atropine group was significantly correlated with the baseline adjustment range (β =-0.71,P＜0.001).Conclusions 0.01％ and 0.02％ atropine show similar effects on pupil diameter and accommodation amplitude after 12 months of treatment in myopic children.

Objective To explore the influencing factors of different bowel preparation before colonoscopy on the intestinal cleanliness and polyp detection rate .Methods From March to August in 2018, at the Center of Endoscopy of Huashan Hospital Affiliated to Fudan University , the patients who underwent colonoscopy were selected and their general data of bowel preparation regimens were collected .Self-factors of the patients, different bowel preparation regimens , bowel preparation quality and polyp detection rate were observed.The quality of bowel preparation was evaluated by Boston bowel preparation scale (BBPS).T test, and analysis of variance and chi-square test were used for statistical analysis .Results Among 1008 patients who underwent colonoscopy , there were 506 males and 502 females, and average age was (57.3 ±13.7) years. There were statistically significant differences in BBPS score of patients with different body mass index (BMI), Parkinson disease and history of abdominal surgery (F=3.319, t=-2.060 and -2.544;all P<0.05).The BBPS score of patients with three-day low residue diet before examination was higher than that of those without preparation before examination (6.04 ±2.50 vs.5.54 ±2.73), and the difference was statistically significant (t=2.514, P=0.010).The BBPS scores of 2000 mL polyethylene glycol electrolyte lavage solution (PEG) taken once , 2000 mL PEG taken separately , 3000 mL PEG taken once and 3000 mL PEG taken separately were 5.06 ±2.88, 6.11 ±2.44, 5.94 ±2.32 and 6.10 ±2.47, respectively, and the difference was statistically significant (F=7.242,P<0.01).There were significant differences in polyp detection rates among the patients with different age , gender, BMI, and with history of constipation , hypertension and diabetes mellitus (χ2 =33.170, 8.489, 12.024, 4.034, 26.790, 10.381;all P<0.05).The polyp detection rate of patients with oral methyl silicone oil was higher than that of patients without oral methyl silicone oil (52.6％, 30/57 vs.29.7％, 221/744), and the difference was statistically significant (χ2 =12.934, P<0.01).Age (odds ratio (OR)=1.328, 95％confidence interval (CI) 1.162 to 1.517) and BMI (OR=1.412, 95％CI 1.115 to 1.787) were independent risk factors for polyp detection rate .Conclusions Parkinson disease, history of abdominal surgery and BMI are the related factors affecting the quality of bowel preparation before colonoscopy .Age and BMI are independent risk factors for polyp detection rate .

Objective:To investigate the relationships of expectation gap of postpartum support with perceived stress and postpartum depression, and the mediating role of the former in the association between the latter two.Methods:A total of 278 convenient sample of puerperas at 6-8 weeks after delivery from June to August in 2019 in Shenzhen Hospital of Southern Medical University were investigated with the Perceived Stress Scale, the Chinese version of the Postpartum Social Support Questionnaire, and the Edinburgh Postnatal Depression Scale. Structure equation model was established and Bootstrap method was used to explore the direct and indirect effects of these variables.Results:The perceived stress score, and expectation gap of postpartum support score were (26.50±2.50), (25.30±5.79), respectively; and the postpartum depression score was (14.60±2.10). The incidence of postpartum depression(defined as postpartum depression score ≥10) was 37.4%(104/278). Path analysis showed that the model was well fitted (χ 2/ df was 0.265, Tucker-Lewis index was 1.0, comparative fit index was 1.0,root mean square of approximate error was 0, root mean square of standard deviation and residual error was 0.04). Perceived stress positively correlated with expectation gap of postpartum support, and postpartum depression ( P<0.05). Expectation gap of postpartum support positively correlated with postpartum depression ( P<0.05). The effect of perceived stress on postpartum depression was partially mediated by expectation gap of postpartum support (Estimate was 0.285, 95% CI 0.197-0.352). Conclusions:Perceived stress had direct or indirect effect via expectation gap of postpartum support on postpartum depression. This indicated that the medical staff can build a comprehensive support system, reduce the experience of perceived stress among puerperas, improve social support satisfaction, and thus reduce the incidence of postpartum depression.

Objective To study the clinical and pathological characteristics of early gastric cancer ( EGC) and to evaluate the value of blue laser imaging combined with magnification endoscopy ( BLI-ME) in the diagnosis of EGC. Methods A retrospective study was conducted on data of 255 patients with EGC diagnosed in Huashan Hospital from January 2014 to January 2017, including 33 cases of preoperative BLI-ME intensive examination. According to the Japanese classification of gastric carcinoma of Japanese Gastric Cancer Association, the EGCs were histopathologically divided into differentiated and undifferentiated subtypes. Clinical characteristics, endoscopic features, pathological type, lymph node metastasis, and lesion characteristics of BLI-ME were analyzed. Results Among the 255 cases of EGC, 164 cases ( 63. 31％) were male, 242 cases ( 94. 90％) were over 40 years old, 182 cases ( 71. 37％) belonged to differentiated type, 93 cases ( 36. 47％) were located in gastric antrum, 92 cases ( 36. 08％) were type 0-Ⅱc under endoscopy, and 37 cases (14. 51％) had lymph node metastasis. Comparative analysis showed that the lymph node metastasis rate was significantly lower in mucosal carcinoma compared to submucosal carcinoma[ 5. 04％(7/139) VS 25. 86％ (30/116),χ2=22. 109, P=0. 000], lower in differentiated carcinoma compared to undifferentiated carcinoma[9. 89％ (18/182) VS 26. 03％ (19/73), χ2=10. 938, P=0. 002], and lower in tumors with maximum diameter of lesion≤2. 0 cm compared to maximum diameter of lesion>2. 0 cm [ 9. 88％ ( 16/162 ) VS 22. 58％ ( 21/93 ) , χ2 =7. 687, P=0. 009 ] . Among the 33 cases undergoing BLI-ME, differentiated EGC was mainly fine-network pattern (13. 64％, 3/22), intralobular loop pattern (ILL)-1 (59. 09％, 13/22) and ILL-2 (22. 73％, 5/22), whereas undifferentiated subtype patients were characterized as ILL-2 ( 45. 45％, 5/11 ) and corkscrew pattern ( 54. 55％, 6/11 ) . Conclusion The incidence of EGC is higher in male with age over 40 years. Gastric lesions occur most frequently in the antrum, and the most common microscopic morphology is 0-Ⅱc type. Tumor>2. 0 cm or invasion of submucous layer, and undifferentiated carcinoma are prone to lymph node metastasis. The assessment of mucosal microvascular pattern and micro surface structure under BLI-ME facilitate to determine the pathological type of EGC.

Objective: To compare the efficacy and safety of plasma exchange (PE) combined with double plasma absorption and simple PE in the treatment of acute-on-chronic liver failure. Methods: We retrospectively analyzed 251 cases of acute-on-chronic liver failure treated with artificial liver treatment since January 2015. Changes in clinical manifestations, laboratory tests, and complications of the patients before and after different modes of treatment were compared and short-term efficacy was tracked. In accordance with different data, t-test, Pearson's chi-squared test and Fisher's exact test were used for statistical analysis. Results: The effectiveness of low-volume PE combined with double plasma molecular adsorption system (DPMAS) and equal amount of PE combined with DPMAS was significantly better than simple PE (83.7%, 84.05% and 82.15 vs 55.6%, P < 0.05) in early stage of liver failure. In late-stage of liver failure, there was no significant difference in the treatment efficiency of each group (P > 0.05). Bilirubin and bile acid levels were significantly decreased in combined treatment groups than that to simple PE group (P < 0.05). PTA and albumin improvement rate of DPMAS PE groups were significantly lower than that of simple PE group (P < 0.05). There was no statistical difference in adverse reactions between each group. Conclusion PE combined with DPMAS improves the treatment efficiency of early hepatic failure and decrease dosage of plasma when compared with simple PE. A beforehand DPMAS treatment after PE treatment can improve the adverse effects of DPMAS on blood coagulation function and albumin levels.
