Objective To investigate the current status of agitated behaviors among institutionalized elderly with dementia. Methods The Cohen-Mansfield Agitation Inventory (CMAI) and General Information questionnaire were used to collect information of agitated behaviors among 141 institutionalized elderly with dementia in a long-term care facility in Guangzhou. Results Nearly 90.07%(127/141) of the elderly with dementia had the symptoms of agitation. Among the four categories of the agitated behaviors, the incidence for physically non-aggressive behaviors (82.27%, 116/141) was the highest, followed by physically aggressive behaviors (78.72% , 111/141), verbally non- aggressive behaviors (74.47%, 105/141) and verbally aggressive behaviors (64.54%, 91/141). Spitting, repetitive sentences or questions, complaining occurred frequently. Conclusions The incidence of the agitated behaviors was high and the manifestation and types of agitated behaviors were varied, which should be paid attention to by the institution. It is necessary to develop the personalized, systematic, standardized nursing intervention to provide the support for caregivers and help the elderly with dementia to cope with agitation.

Bariatric surgery has been proven to be an effective way to relieve obesity and related metabolic diseases. Complications after bariatric surgery mainly include postoperative bleeding, anastomotic leakage, gastroesophageal reflux, dumping syndrome and so on. Deep vein thrombosis is a rare complication, with low incidence in many literatures. However, deep vein thrombosis is an important cause of pulmonary embolism. Once pulmonary embolism occurs, the difficulty of treatment and mortality are both high. The authors summarize the related literature on venous thromboembolism after bariatric surgery, and briefly describe the strategies of prevention and treatment of venous thromboembolism.

Laparoscopic bariatric and metabolic surgery in China began in 2000. After 20 years of development, it has realized the transformation from nothing to existence and then to rapid development. In this paper, the number of Chinese and English literatures on weight loss and metabolism published in China in the past 20 years, the source of literature institutions, published journals, literature types, key words and other aspects are analyzed. The results show as follows: the number of published literatures is generally increasing, bariatric surgery has changed from gastric bypass and gastric banding to gastric bypass and sleeve gastrectomy, revisional surgery and intestinal flora have been the focus of research in recent years. However, the development of laparoscopic bariatric surgery in China is still in its infancy, and there is few high-level evidence-based multicenter prospective randomized controlled study. Therefore, the authors suggest that more and larger sample, multicenter, randomized controlled studies should be carried out in the future and it requires to develop guidelines suitable for Chinese population. In order to promote the further development of bariatric and metabolic surgery in China, we should establish national data and register clinical data, strergthon the combination of clinical research and basic research and conduct deeper research based on the database.

Objective:To compare the safety of continuous suture and interrupted suture in Laparoscopic Sleeve Gastrectomy and Omentopexy.Methods:The retrospective study include 121 patients who underwent Laparoscopic Sleeve Gastrectomy and Omentopexy in the Department of Obesity and Metabolic Surgery of the First Affiliated Hospital of Jinan University from January 2019 to March 2020.Among the 121 patients, 40 were males and 81 females, with an average age of (30.17±10.16) and (27.10±11.03), respectively. Among them, 70 patients used continuous suture during OP (continuous suture group), and 51 patients used intermittent suture (interrupted suture group). The operation time, intraoperative blood loss, postoperative pain score, postoperative complications were compared between the two groups. Normally distributed measurement data were measured as (mean ± standard) deviation ( Mean± SD), and t test was used to count the comparison between the two groups. The χ2 test was used to compare the measurement data between groups. The rank data used Wilconxon rank sum test. Results:(1) Intraoperative conditions: the operative time and intraoperative blood loss in the continuous suture group were (124.89±37.69) min and (7.3±2.5) mL, respectively. In the interrupted suture group, the above indexes were (124.80±35.53) min and (7.0±2.5) mL, respectively. There was no significant difference between the two groups ( t=0.012, 0.709, P>0.05). (2) Postoperative conditions: postoperative pain score and postoperative hospital stay in the continuous suture group were: mild pain in 45 cases, moderate pain in 25 cases, painless and severe pain in 0 cases, (9.3±3.2) d, respectively. In the interrupted suture group, the above indicators were 39 cases of mild pain, 12 cases of moderate pain, 0 cases of painless and severe pain, (8.7±2.1) d, and there was no statistical significance between the two groups ( Z=-1.431, P>0.05, t=1.149, P>0.05). In the continuous suture group, postoperative abdominal distension occurred in 8 cases, nausea and vomiting in 32 cases, gastroesophageal reflux in 17 cases by upper digestive tract imaging, contrast agent slowly passed through the residual stomach/anastomotic site in 14 cases, gastric volvulus in 6 cases, and no postoperative infection or anastomotic leakage occurred. In the interrupted suture group, the above indexes were 10 cases, 25 cases, 14 cases, 10 cases, gastric volvulus in 1 cases, and no postoperative infection or anastomotic leakage occurred. There was no significant difference in the above indicators between the two groups ( χ2=1.559, 0.010, 0.155, 0.003, 1.308, P>0.05). Conclusions:In laparoscopic sleeve gastrectomy and omentopexy, there is no significant difference between the continuous suture and interrupted suture in terms of operation time, intraoperative blood loss and postoperative complications. The surgeon can choose a suitable suture method based on his own judgment and experience.

Objective:To investigate the regulation of intestinal microbiota by Roux-en-Y gastric bypass (RYGB) on patients with obesity or obesity combined with diabetes.Methods:The retrospective and descriptive study was conducted. The stool samples before and after surgery and clinical data of 20 patients with obesity, including 9 simple obesity cases and 11 obesity combined with diabetes cases, who underwent RYGB in the First Affiliated Hospital of Ji′nan University from July 2016 to August 2017 were collected. There were 11 males and 9 females, aged (33±11)years. Observation indicators: (1) changes in composition and structure of intestinal microflora; (2) changes of intestinal microflora in simple obesity patients after operation; (3) changes of intestinal microflora in obesity combined with diabetes patients after operation. Follow up was conducted using telephone interview or outpatient examinations to detect the body mass, the application of antimicrobial agent and the blood glucose control of patients. According to the unified training points, the stool samples were collected and stored into the DNA stabilizer, and then conducted to laboratory analysis within 45 hours. The follow up was up to November 2018. Measurement data with normal distribution were represented as Mean± SD, and independent-samples t test was used for inter-group comparison and paired-samples t test was used for intra-group comparison. Measurement data with skewed distribution were represented as M( Q1, Q3), and Wilcoxon signed rank test of two independent samples was used for inter-group comparison. Count data were described as absolute numbers, and the chi-square test, ANOSIM analysis, linear discriminant (LEfSe) analysis and the Metastats analysis were used for inter-group comparison. Results:(1) Changes in composition and structure of intestinal microflora. The Shannon index of α diversity of preoperative intestinal microflora in simple obesity patients and obesity combined with diabetes patients was 4.37±0.69 and 4.47±0.85, respectively, showing no significant difference between them ( t=0.28, P>0.05). Results of preoperative LEfSe analysis showed that there were differences in the bacterial abundance of Firmicutes and Bacteroidea between simple obesity patients and obesity combined with diabetes patients. The abundances of Parasutterella in simple obesity patients and obesity combined with diabetes patients was 0.000 113 0(0, 0.004 378 2) and 0.008 464 0(0.001 325 7, 0.034 983 1), respectively, showing a significant difference between them ( Z=2.12, P<0.05). Results of preoperative PCoA analysis showed that the contribution rates of principal component 1, principal component 2 and principal component 3 were 24.98%, 22.24% and 16.33% in simple obesity patients and obesity combined with diabetes patients and results of ANOSIM comparison showed that there was no significant difference in preoperative intestinal microflora between them ( r=?0.11, P>0.05). The Shannon index of α diversity of postoperative intestinal microflora in simple obesity patients and obesity combined with diabetes patients was 4.60±0.65 and 4.66±0.40, respectively, showing no significant difference between them ( t=0.24, P>0.05). Results of postoperative LEfSe analysis showed that there were differences in the bacterial abundance of Bacteroidea, Proteus and Firmicutes between simple obesity patients and obesity combined with diabetes patients. The abundances of Morganella and Coprococcus_2 in simple obesity patients and obesity combined with diabetes patients were 0.000 192 0(0.000 011 9,0.001 569 0), 0(0,0) and 0(0,0), 0.000 054 1(0,0.000 419 0), showing significant differences between them ( Z=2.70, 2.29, P<0.05). (2) Changes of intestinal microflora in simple obesity patients after operation. There were 10 genera of bacteria of intestinal bacteria changing after surgery, including 7 species of bacteria increasing in the Firmicutes and the Proteobacteria as Veillonella, Morganella, Granulicatella, Aeromonas, Streptococcus, Rothia and Megasphaera and the bacteria decreasing in the Firmicutes and the Actinobacteria as Ruminococcus_torques_group, Romboutsia and Erysipelo-trichaceae_UCG-003. Results of LEfSe analysis showed that the bacteria significantly enriched in simple obesity patients before surgery were Ruminococcus_torques_group, Romboutsia and Erysipelotri-chaceae_UCG-003, belonging to Firmicutes, and the bacteria significantly enriched in simple obesity patients after surgery were Rothia, Granulicatella, Enterococcus, Streptococcus, Megasphaera, Veillonella, A eromonas and Morganella, belonging to Actinobacteria, Firmicutes and Proteobacteria. (3) Changes of intestinal microflora in obesity combined with diabetes patients after operation. There were 16 bacteria of intestinal bacteria increasing after surgery, including Streptococcus, Veillonella, Haemophilus, Pluralibacter, Gemella, Lachnospiraceae_NC2004_group, Granulicatella,Aeromonas, uncultured_ bacterium_f_ Saccharimonadaceae, R uminiclostridium_9, Butyricicoccus, Fusobacterium, Anaerotruncus, Fusicateni-bacter, Klebsiella and E ubacterium_eligens_group, which belonged to the Firmicutes and the Proteo-bacteria. Results of LEfSe analysis showed that the bacteria significantly enriched in obesity combined with diabetes patients before surgery were Fusicatenibacter, Tyzzerella_3 and Butyricicoccus, belonging to the Firmicutes, and the bacteria significantly enriched in obesity combined with diabetes patients after surgery were Gemella, Granulicatella, Enterococcus, Streptococcus, Lachnospiraceae_NC2004_group, Eubacterium_eligens_group, Anaerotruncus, Ruminiclostridium_9, Anaeroglobus, Veillonella, Fusobacterium, uncultured_bacterium_f_Saccharimonadaceae, Aeromonas, Klebsiella, Pluralibacter, Proteus and Haemophilus, belonging to the Firmicutes and the Proteobacteria. Conclusions:RYGB can significantly increases the intestinal microflora abundance in simple obesity patients and obesity combined with diabetes patients. The two types of patients have specific changes in intestinal microflora at the genus level.
