With the popularization of digestive endoscopy in children, colonoscopy has been widely used. As the basis of digestive endoscopy, bowel preparation directly affects the diagnosis and treatment results of colonoscopy. Compared with adults, the functioning of important organs of children is immature, and their ability of cognition, communication and tolerance are weak. Their structure of the digestive tract is also significantly different in different ages. However, there have been no existing evidence-based guidelines on bowel preparation for digestive endoscopy of Chinese children. Therefore, it is important to develop evidence-based guidelines for bowel preparation combined with the clinical practice in China. In order to provide guidance and decision-making basis for Chinese pediatricians, we collaborated with multidisciplinary experts, based on existing evidence, adopted the grading of recommendations assessment, development and evaluation (GRADE) approach, followed the Reporting Items for Practice Guidelines in Healthcare (RIGHT) to develop this guideline for bowel preparation related to the diagnosis and treatment of children's digestive endoscopy.
ObjectiveTo analyze and explore the thyroid defunctionalization method for preoperative preparation of hyperthyroidism patients in endoscopic thyroid surgery. MethodsThe clinical data of 45 cases of hyperthyroidism treated with endoscopic surgery in this hospital from June 2009 to June 2014 were analyzed retrospectively. These patients were divided into study group (n=20) and control group (n=25) according to the preoperative preparation method, the study group was prepared with thyroid defunctionalization method, the control group was prepared with antithyroid drugs and iodine. The intraoperative blood loss, conversion to open surgery, and postoperative complications were compared in these two groups. ResultsThe intraoperative blood loss and the operation time of the study group were significantly less than those of the control group﹝intraoperative blood loss: (120.32±50.26) mL versus (200.63±60.95) mL, P < 0.05; operation time: (120.43±40.56) min versus (180.76±50.92) min, P < 0.05﹞. There was no case of conversion to open surgery in the study group, there were three cases of conversion to open surgery in the control group. The incidence of postoperative complications of the study group was significantly lower than that of the control group﹝10% (2/20) versus 24% (6/25), P < 0.05﹞. ConclusionThyroid defunctionalization method is more suitable as compared with the traditional method for the preoperative preparation of hyperthyroidism in endoscopic thyroid surgery.

Objective To investigate the effect and clinical significance of 3 d and 1 d bowel preparation method for colorectal carcinoma surgery on preoperative gut mucosal barrier function. Methods Plasma levels of D-lactate (D-LAC), diamine oxidase (DAO) and endotoxin (ET) were measured at 2 h before operation in 3 d bowel preparation group (50 cases) and 1 d bowel preparation group (50 cases), 25 cases of inguinal hernia were included as control group. D-LAC, DAO and ET were detected by using enzymatic spectrophotometric assay, spectrophotometric assay and limulus lysate test with azo chromogenic substrate, respectively. Results Preoperative plasma levels of D-LAC, DAO and ET in 3 d bowel preparation group were (10.25±1.43) mg/L, (5.82±0.80) U/ml and (10.11±1.41) ng/L respectively. In 1 d bowel preparation group the corresponding values were (10.19±1.35) mg/L, (5.80±0.81) U/ml and (9.82±1.35) ng/L respectively. There were no significant differences between 3 d and 1 d bowel preparation group (Pgt;0.05), compared with hernia group, 1 d and 3 d bowel preparation group were also no statistically significant differences (Pgt;0.05). Conclusions There are no significant preoperative gut mucosal barrier function damages in patients with 1 d and 3 d bowel preparation for colorectal carcinoma surgery, 1 d bowel preparation for colorectal carcinoma surgery can be performed in colorectal carcinoma patients, and 3 d bowel preparation can be used for certain special colorectal carcinoma patients.
ObjectiveTo study and compare the effects of inhaled preparations with open airway and conventional inhaled preparation on asthma patients.MethodsThe patients diagnosed with asthma and treated with the same inhaled preparation only who visited the outpatient department of West China Hospital of Sichuan University, were selected as the study subjects from April to September, 2019. The subjects were divided into the test group and the control group according to random ratio 1∶1. The conventional inhaled preparations were used in the control group. The inhaled preparations with open airway were used in the test group. Asthma control, life quality and treatment satisfaction rate were compared between the two groups after 3 months.ResultsA total of 150 subjects were included and one case dropped-off, then 149 effective subjects were obtained in which 75 cases in the test group and 74 cases in the control group. After 3 months’ treatment of inhaled preparations, the proportion of effective asthma control patients in the test group was higher than that in the control group, and the number of patients satisfied with the treatment of inhaled preparations was higher than that in the control group, with statistically significant differences (all P<0.05). The life quality of patients in both groups was improved compared with baseline, and the difference was statistically significant (P<0.05). However, the increase of scores in the test group was more than that in the control group, and the difference was also statistically significant (P<0.05). ConclusionInhaed preparations with open airway is superior to conventional inhaled preparation on asthma patients in asthma control, life quality and treatment satisfaction rate.
Brain-computer interface (BCI) has high application value in the field of healthcare. However, in practical clinical applications, convenience and system performance should be considered in the use of BCI. Wearable BCIs are generally with high convenience, but their performance in real-life scenario needs to be evaluated. This study proposed a wearable steady-state visual evoked potential (SSVEP)-based BCI system equipped with a small-sized electroencephalogram (EEG) collector and a high-performance training-free decoding algorithm. Ten healthy subjects participated in the test of BCI system under simplified experimental preparation. The results showed that the average classification accuracy of this BCI was 94.10% for 40 targets, and there was no significant difference compared to the dataset collected under the laboratory condition. The system achieved a maximum information transfer rate (ITR) of 115.25 bit/min with 8-channel signal and 98.49 bit/min with 4-channel signal, indicating that the 4-channel solution can be used as an option for the few-channel BCI. Overall, this wearable SSVEP-BCI can achieve good performance in real-life scenario, which helps to promote BCI technology in clinical practice.
Melanin nanoparticles (MNPs) not only retain the inherent characteristics of melanin (metal ion chelation, photothermal conversion property, etc.), but also can exhibit more excellent properties, such as high dispersion stability, good biocompatibility and biodegradability, etc. Furthermore, these performances can be enhanced to target the specific sites and treat diseases by the surface modification or combination with functional substance. In this paper, the characteristics, preparation methods and applications of MNPs were reviewed. It provides a reference for further development of application for MNPs, and theoretical basis for practice in biology, medicine and so on.
ObjectiveTo analyze the effect of microecological preparation on digestive tract complications and nutritional status after esophageal cancer surgery.MethodsA total of 146 patients with esophageal cancer admitted to the Department of Thoracic Surgery, Renmin Hospital of Wuhan University from October 2017 to June 2019 were selected. There were 91 males and 55 females, aged 65 (61.9±8.2) years. They were randomly divided into two groups (an observation group and a control group, n=73 in each group) according to whether microecological preparation was given when they could take food one week after the surgery. Nutritional status and the incidence of gastrointestinal complications including anorexia, acid reflux, nausea, vomiting and diarrhea (≥3 times per day) in the first month after operation were compared between the two groups.ResultsThe incidence of anorexia, nausea, diarrhea (≥3 times per day), anastomotic fistula and stenosis in the observation group was lower and the index of nutritional status was higher than those in the control group within one month after the operation (all P<0.05). There was no statistically significant difference in acid reflux, vomiting, lung infection and incision infection between the two groups (all P>0.05).ConclusionMicroecological preparation can regulate gastrointestinal microecological balance, improve nutritional status, reduce the incidence of gastrointestinal complications and accelerate the postoperative rehabilitation.
ObjectiveTo systematically review the efficacy of discharge preparation service in elderly patients with chronic diseases.MethodsCNKI, WanFang Data, VIP, Web of Science, The Cochrane Library, PubMed and EMbase databases were electronically searched to collect randomized controlled trails (RCTs) on the discharge preparation service for elderly patients with chronic diseases from January, 2000 to January, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 7 RCTs, involving 884 patients were included. The results of meta-analysis showed that: after the hospitalization preparation service, the incidence of acute complication (RR=0.38, 95%CI 0.15 to 0.98, P=0.04), patient compliance behavior (SMD=0.54, 95% CI 0.25 to 0.83, P=0.000 3), exercise capacity (SMD=2.65, 95%CI 0.25 to 5.04, P=0.03), and nursing satisfaction (SMD=0.71, 95%CI 0.10 to 1.33, P=0.02) significantly improved. However, there were no significant differences in emergency hospital admission for acute complications (RR=0.25, 95%CI 0.06 to 1.11, P=0.07), self-care ability (SMD=2.18, 95%CI −1.02 to 5.38, P=0.18), activity of daily living (ADL) (SMD=0.56, 95%CI −0.47 to 1.59, P=0.28).ConclusionsThe current evidence shows that after implementation of the discharge preparation service, the incidence of acute complication, compliance behavior, exercise ability, and service satisfaction of the elderly patients with chronic diseases are significantly improved. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusion.
ObjectiveTo observe the effectiveness and safety of pseudomonas aeruginosa preparation in treating refractory seroma after breast cancer surgery.MethodsA total of 76 patients with refractory seroma after breast cancer surgery who underwent surgery from October 2018 to August 2019 in our hospital were selected. The subjects were randomly divided into two groups. The patients in the control group (n=36) adopted negative pressure drainage connected with indwelling needle in the lower position of the seroma chamber; on the basis, patients in the experimental group (n=400) were injected with pseudomonas aeruginosa preparation into the seroma chamber. The drainage time, total drainage volume, recurrence rate, and incidence of complications of the two groups were compared.ResultsThere were 4 cases in the experimental group and 3 cases in the control group were lost followed-up, so only 69 cases enrolled in data analysis. The drainage time, total drainage volume, and the recurrence rate of the experimental group were all shorter or less than those of the control group (P<0.05). But there was no significant difference in the incidence of complications between the experimental group and the control group (P>0.05), such as fever, inflamed skin, and infection of incision.ConclusionPseudomonas aeruginosa preparation is an effective treatment for refractory seroma after breast cancer surgery, which can shorten the drainage time and promote wound healing.
