ABSTRACT

Objective:To investigate the effect of nutritional status and comfortability of early postoperative diet of patients following sedated colonoscopic polypectomy.Methods:A total of 300 patients who undergoing sedated colonoscopic polypectomy were randomly divided into normal group and experimental group 1, group 2, with 100 cases in each group. The control group received total fasting with intravenous infusion, oral clear fluids were begun up on the first postoperative day and solid foods on the fourth day. In the experimental group 1 and group 2, clear fluids were begun up to six hours or two hours after surgery, respectively, followed by semi-liquid on the first postoperative day, and solid food three days later. The clinical outcomes such as time of first defecation, hospitalization time, abdominal pain, hypoglycemial reaction, bleeding volume and nausea/vomiting was recorded between three groups. In addition, the nutritional status and comfortability was compared by using serum albumin detection and Visual Analogue Scale (VAS), respectively.Results:The time of first defecation were (22.46±2.96) hours and (21.54±2.17) hours in the experimental group 1 and group 2, significantly shorter than that in the control group (26.37±4.87) hours; meanwhile, the time of first defecation were significantly decreased in the experimental group 2 compared to the experimental group 1, the difference was statistically significant ( F value was 51.812, P<0.05). The rate of hypoglycemial reaction were 5.10% (5/98) and 2.04% (2/98) in the experimental group 1 and group 2, significantly lower than that in the control group 13.40% (13/97), the difference was statistically significant ( χ2 value was 10.582, P<0.05). After 5th day of surgery, the level of serum albumin were (36.16±6.44) g/L and (36.55±6.57) g/L in the experimental group 1 and group 2, significantly higher than those in the control group (33.97±5.91) g/L, the difference was statistically significant ( F value was 4.732, P<0.05). However, there was no significant difference in the VAS scores among the three groups ( P>0.05). Conclusion:Two hours after sedated colonoscopic polypectomy oral feeding can obviously promote the recovery of gastrointestinal function, which does not increase the occurrence of postoperative complications, and promote the postoperative recovery of the patients.

ABSTRACT

Objective To analyze the epidemic characteristics and influencing factors of influenza outbreaks in Xinwu District of Wuxi City from 2017 to 2019, and to provide a basis for the prevention and control of influenza outbreaks in schools. Methods The 2017-2019 influenza data was retrieved from the China Influenza Surveillance Information System and the Public Health Emergency Management System. A descriptive epidemiology method was used to analyze the characteristics of the influenza outbreaks. The related factors on the epidemic intensity and duration were analyzed. Results From 2017 to 2019, a total of 26 influenza outbreaks occurred in Xinwu District, with a cumulative total of 927 cases and an average prevalence rate of 1.74%. The outbreaks mainly occurred between November and April of the following year, accounting for 100%. The outbreaks all occurred in schools, with primary schools accounting for 88.46% (23/26) and kindergartens accounting for 11.54% (3/26) of the total. The main influenza viruses that caused influenza outbreaks were B/Victoria and B/Yamagata, which accounted for 65.60% (164/250) and 16.40% (41/250), respectively, followed by influenza A/H3N2, which accounted for 16% (40/250). The epidemic intensity was related to the number of students (P < 0.05), and the duration of the epidemic was related to the type of schools and the reporting time of the epidemic (P < 0.05). Conclusion The outbreaks of influenza had obvious seasonality, and occurred mainly in schools. Improving the timeliness of epidemic reporting and taking timely control measures are the key to controlling influenza outbreaks in schools.

ABSTRACT

Objective@#To investigate the image quality of ultralow-dose CT (ULDCT) of the chest reconstructed using a cycle-consistent generative adversarial network (CycleGAN)-based deep learning method in the evaluation of pulmonary tuberculosis. @*Materials and Methods@#Between June 2019 and November 2019, 103 patients (mean age, 40.8 ± 13.6 years; 61 men and 42 women) with pulmonary tuberculosis were prospectively enrolled to undergo standard-dose CT (120 kVp with automated exposure control), followed immediately by ULDCT (80 kVp and 10 mAs). The images of the two successive scans were used to train the CycleGAN framework for image-to-image translation. The denoising efficacy of the CycleGAN algorithm was compared with that of hybrid and model-based iterative reconstruction. Repeated-measures analysis of variance and Wilcoxon signedrank test were performed to compare the objective measurements and the subjective image quality scores, respectively. @*Results@#With the optimized CycleGAN denoising model, using the ULDCT images as input, the peak signal-to-noise ratio and structural similarity index improved by 2.0 dB and 0.21, respectively. The CycleGAN-generated denoised ULDCT images typically provided satisfactory image quality for optimal visibility of anatomic structures and pathological findings, with a lower level of image noise (mean ± standard deviation [SD], 19.5 ± 3.0 Hounsfield unit [HU]) than that of the hybrid (66.3 ± 10.5 HU, p 0.908). The CycleGAN-generated images showed the highest contrast-to-noise ratios for the pulmonary lesions, followed by the model-based and hybrid iterative reconstruction. The mean effective radiation dose of ULDCT was 0.12 mSv with a mean 93.9% reduction compared to standard-dose CT. @*Conclusion@#The optimized CycleGAN technique may allow the synthesis of diagnostically acceptable images from ULDCT of the chest for the evaluation of pulmonary tuberculosis.

ABSTRACT

Objective:To explore the application value of primary trauma treatment (PTC) teaching mode in special professional cardiopulmonary resuscitation (CPR) guide training.Methods:Cluster sampling method was adopted, and the residents' committee selected special occupation population from every town/sub-district office in the southern mountainous area of Ningxia Hui Autonomous Region for CPR training. A monthly session was held from January to December 2019, with personnel trained by traditional operation teaching and individual practice method from January to June 2019 as the control group and personnel trained by PTC teaching mode from July to December 2019 as the observation group. The two groups of trainers, training objectives and assessment standards were consistent. Questionnaire survey was conducted at the beginning and end of each training period, including the degree of mastery of first-aid knowledge and skills and the level of self-efficacy, etc., to evaluate the training effect.Results:There were 503 trainees in each group, and there was no significant difference in gender, age, education and occupation distribution between the two groups. There was no significant difference in the first aid principles, CPR skill level and self-efficacy between the two groups before the training. The first aid principle, CPR skills level and self-efficacy of the two groups after training were all improved, and the principle of first aid and CPR skills level in the observation group was obviously higher than that in the control group (first aid related concepts: 4.39±0.76 vs. 3.87±0.89, gold life-saving time: 5.71±0.49 vs. 4.53±0.62, the meaning of the first witnesses: 5.33±0.82 vs. 4.18±0.78, cardiac, respiratory cardiac arrest in the judgment: 5.12±0.73 vs. 4.07±0.73, CPR skills: 5.29±0.64 vs. 4.15±0.71, all P < 0.05). The self-efficacy score of the observation group was significantly higher than that of the control group (emergency attitude: 18.17±1.24 vs. 17.35±1.25, self-efficacy: 13.56±1.54 vs. 11.35±1.26, behavioral intention: 9.56±0.84 vs. 8.92±0.95, all P < 0.05). Conclusion:The application of PTC teaching mode in the training of CPR guidelines for special professions has significant effects, which can effectively help special professions to master CPR knowledge and skills, and has promotion value.

ABSTRACT

Ricin is a highly toxic type 2 ribosome-inactivating protein (RIP) which is extracted from the seeds of castor beans. Ricin is considered a potential bioterror agent and no effective antidote for ricin exists so far. In this study, by structural modification of a retrograde transport blocker Retro-2, a series of novel compounds were obtained. The primary screen revealed that compound has an improved anti-ricin activity compare to positive control. pre-exposure evaluation in Madin-Darby Canine Kidney (MDCK) cells demonstrated that is a powerful anti-ricin compound with an EC of 41.05 nmol/L against one LC (lethal concentration, 5.56 ng/mL) of ricin. Further studies surprisingly indicated that confers post-exposure activity against ricin intoxication. An study showed that 1 h post-exposure administration of can improve the survival rate as well as delay the death of ricin-intoxicated mice. A drug combination of with monoclonal antibody mAb4C13 rescued mice from one LD (lethal dose) ricin challenge and the survival rate of tested animals is 100%. These results represent, for the first time, indication that small molecule retrograde transport blocker confers both and post-exposure protection against ricin and therefore provides a promising candidate for the development of anti-ricin medicines.

ABSTRACT

Objective@#To define radiographic features that response to serial casting and bracing for progressive early-onset scoliosis (EOS).@*Methods@#A retrospective study of a total of 20 patients (10 females and 10 males) with complete radiographic data diagnosed as progressive early onset scoliosis treated with serial cast or brace for at least 12 months in the 306th Hospital of PLA from June 2011 to April 2018. Ages at initial diagnosis were all less than 5 years old. They were divided into two groups according to the main curve degree, those with cobbs angles more than 50 degree treated with serial cast, or else with brace. All the cases have radiographs of pretreatment, posttreatment, and last follow-up, and anteroposterior (lateral) film of the full length spine in standing position were taken to evaluate magnitudes and balance of coronal and sagittal malformations. We compared the general data of the two groups by independent sample t test and that of pretreatment, posttreatment and the last follow-up by paired-sample t test.@*Results@#According to the effective standard of not less than 10 degrees improvement, 9 of them were effective, 4 cast and 5 brace, the effective rates were 44.44% and 45.45%, 3 cases from brace group progressed. The magnitudes of the main curve improved significantly after the first treatment of cast and brace (55.4±24.36 vs 42.35±23.62) degree (t=5.850, P=0.000), and at the last follow up, the curve decreased slightly compared of that before interventions (55.4±24.36 vs 51.8±26.33). The compensatory curves, segmental kyphosis, thoracic kyphosis, lumbar lordosis, balance of both coronal and sagittal also had no significant differences between the primal and the latest follow up. The widths 159.63±19.27 mm, 160.81±14.54 mm, 176.08±28.10 mm (t=3.942, P=0.001; t=-3.096, P=0.006) and heights 153.78±29.24 mm, 161.14±29.53 mm, 175.01±36.91 mm of the thoracic were significantly different between pre-posttreatment and the last follow up (t=-5.950, P=0.000; t=-3.997, P=0.001). Serial cast and brace application can preserve the growth of the thorax.@*Conclusion@#Serial cast and brace are viable growth friendly methods to deal with progressed EOS, Although a cure improvement cannot be always expected, they can stabilize relatively large curves in young children and may help delay eventual surgical intervention.

ABSTRACT

Objective@#To investigate the clinical effects of first generation epithelial growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) compared with platinum-based chemotherapy as first-line therapy in advanced lung adenocarcinoma patients with uncommon EGFR mutations.@*Methods@#Clinical data of 4 276 patients diagnosed as advanced lung adenocarcinoma (ⅢB/Ⅳ) underwent EGFR gene detection at the Affiliated Cancer Hospital of Zhengzhou University from January 2012 to February 2018 were collected and 99 cases with uncommon EGFR mutations were selected. The clinical pathological features, treatment outcomes, treatment options and prognosis after first-line treatment of the 99 cases were analysed and compared with other patients with common EGFR mutations.@*Results@#The objective response rates of patients with uncommon EGFR mutations receiving EGFR-TKIs or platinum-based chemotherapy were 33.0% and 27.1%, respectively. The disease control rates were 76.5% and 87.5%, respectively. The progression-free survival (PFS) of patients treated with EGFR-TKIs was 7.2 months, significantly superior than 4.9 months of patients receiving chemotherapy (P=0.009). The overall survival of patients treated with EGFR-TKIs was 14.3 months, significantly worse than 20.7 months of patients receiving chemotherapy (P=0.034). Multivariate analysis showed that distant metastases (P=0.001) and smoking history (P=0.013) were independent prognostic factors for OS of lung adenocarcinoma patients with EGFR uncommon mutations.@*Conclusions@#Compared with chemotherapy, the usage of first generation of EGFR-TKIs as first-line therapy can improve the short-term efficacy of advanced lung adenocarcinoma patients with EGFR uncommon mutations. However, platinum-based chemotherapy shows a longer overall survival.

ABSTRACT

Objective@#To verify the diagnostic value of adenosine deaminase (ADA) for tuberculous pleural effusion. @*Methods@#Forty-three cases with tuberculous pleural effusion and 163 cases with non-tuberculous pleural effusion were consecutively collected. The concentration of ADA in pleural effusion was determined by enzyme kinetics. The receiver operating characteristic (ROC) analysis curve was used to calculate the optimal cut-off value of ADA for diagnosing tuberculous pleural effusion based on the control groups with non-tuberculous pleural effusion. Meanwhile, the specificity and sensitivity of ADA level for diagnosis of tuberculous pleural effusion were compared with previous reports. @*Results@#The concentration of ADA in tuberculous pleural effusion (median 52.5 U/L) was significantly higher than that in non-tuberculous pleural effusion (median 9.8 and 10.6 U/L) (P<0.05). With a cut-off level for ADA of 25 U/L, the diagnostic sensitivity and specificity was 88.0% and 91.0%, respectively. A system review analyzed data from 17 studies with QUADAS score ≥10 points and revealed the cut-off value of ADA to be (28.1±12.8) U/L (range 10.2 to 55.8 U/L) with a sensitivity of 89% (95%CI: 87% to 91%) and a specificity of 89% (95%CI: 88% to 91%). @*Conclusion@#The specificity and sensitivity of ADA for diagnosis of tuberculous pleural effusions should be up to over 85%, while the cut-off value of ADA from different literature reports were diverse.

ABSTRACT

Objective To investigate clinical characteristics and medium-term prognosis of the advanced elderly patients with mild ischemic stroke,and to evaluate the risk factors for poor clinical outcome.Methods The 574 elderly patients with mild acute ischemic stroke admitted in neurology department of our hospital were retrospectively studied from January 2016 to December 2017.All cases were divided into the advanced elderly group(n=276,≥80 years old)and elderly patient group(n=298,60-79 years old).Clinical characteristics were analyzed.After 12-month follow-up,the mid-term prognosis and risk factors for poor clinical outcome(mRS≥ 3)were analyzed in the two groups.Results Compared with the elderly patients,the advanced elderly patients were more often complicated with history of atrial fibrillation,diabetes and stroke(P <0.05).The scores of National Institute of Health stroke scale(NIHSS)and Modified Rankin Scale(mRS)were higher in the advanced elderly patients than in the elderly patients(1.37± 1.03 vs.0.94 ±0.43,2.79± 1.27 vs.1.92 ± 0.66,P<0.001).The proportion of patients receiving anticoagulation treatment were lower in the advanced elderly patients than in the elderly patients,with no significant difference(P >0.05).After an average follow-up of(11.3 ± 1.5) months,the proportions of poor clinical outcome and mortality were higher in the advanced elderly patients than in the elderly patients(63.4% or 175/276 vs.48.0% or 143/298,25.7% or 71/276 vs.16.1% or 48/298,P<0.05).Cox proportional hazard model analysis showed that age,baseline NIHSS score and mRS score,diabetes and stroke history were the risk factors for poor clinical outcome in elderly patients with mild ischemic stroke(all P<0.05).Conclusions The advanced elderly patients with mild ischemic stroke have a severe clinical condition,higher rates of atrial fibrillation,diabetes and stroke history,and poor mid-term prognosis.Age,baseline scores of NIHSS and mRS,diabetes and stroke history are the risk factors for poor clinical outcome in elderly patients with mild ischemic stroke.

ABSTRACT

To define radiographic features that response to serial casting and bracing for progressive early-onset scoliosis (EOS). Methods A retrospective study of a total of 20 patients (10 females and 10 males) with complete radio?graphic data diagnosed as progressive early onset scoliosis treated with serial cast or brace for at least 12 months in the 306th Hos?pital of PLA from June 2011 to April 2018. Ages at initial diagnosis were all less than 5 years old. They were divided into two groups according to the main curve degree, those with cobbs angles more than 50 degree treated with serial cast, or else with brace. All the cases have radiographs of pretreatment, posttreatment, and last follow?up, and anteroposterior (lateral) film of the full length spine in standing position were taken to evaluate magnitudes and balance of coronal and sagittal malformations. We com?pared the general data of the two groups by independent sample t test and that of pretreatment, posttreatment and the last follow?up by paired?sample t test. Results According to the effective standard of not less than 10 degrees improvement, 9 of them were ef?fective, 4 cast and 5 brace, the effective rates were 44.44% and 45.45%, 3 cases from brace group progressed. The magnitudes of the main curve improved significantly after the first treatment of cast and brace (55.4±24.36 vs 42.35±23.62) degree (t=5.850, P=0.000), and at the last follow up, the curve decreased slightly compared of that before interventions (55.4±24.36 vs 51.8±26.33). The compensatory curves, segmental kyphosis, thoracic kyphosis, lumbar lordosis, balance of both coronal and sagittal also had no significant differences between the primal and the latest follow up. The widths 159.63±19.27 mm, 160.81±14.54 mm, 176.08± 28.10 mm (t=3.942, P=0.001; t=-3.096, P=0.006) and heights 153.78±29.24 mm, 161.14±29.53 mm, 175.01±36.91 mm of the thoracic were significantly different between pre-posttreatment and the last follow up (t=-5.950, P=0.000; t=-3.997, P=0.001). Se? rial cast and brace application can preserve the growth of the thorax. Conclusion Serial cast and brace are viable growth friendly methods to deal with progressed EOS, Although a cure improvement cannot be always expected, they can stabilize relatively large curves in young children and may help delay eventual surgical intervention.
