Objective:To explore the efficiency of a modified caries risk assessment tool(MCAT)on caries-risk prediction of children in Nanning.Methods:MCAT was designed based on caries-risk assessment tool(CAT)of American Academy of Pediatric Dentistry(AAPD)and the caries related factors of the primary school children in Guangxi,China.A cohort study was conducted in 332 children aged 3-year-old in kindergarten of Jiangnan District,Nanning,Guangxi.The data were integrated through questionnaires and oral exam-ination.The MCAT data were respectively scored by CAT and Cariogram and the caries-risk of the children was evaluated.The develop-ment of increased average caires incidece over a period of 1.5 years was compared,the predictive capacity of the methods was com-pared.Results:The ranks of caires risk assessed by CAT and Cariogram were significant different(Z=-10.34,P＜0.001),and the consistency of the 2 methods was poor(Kappa=0.234,P＜0.001).After 1.5 years,there was significant statistical difference of the caries prevalence rate between the low-high and moderate-high risk groups,and dmft increments between the moderate-high risk groups e-valuated by CAT(P＜0.05).There was significant difference of the caries prevalence rate between each risk groups and dmft increments between the low-high and moderate-high risk groups evaluated by Cariogram(P＜0.05).The AUC of CAT and Cariogram was 0.571 and 0.722 respectively(P＜0.001).In the prediction models of caries risk,the fitting of CAT was poor(P＜0.001),while that of Cariogram was better(P=1.00).Cariogram analysis showed that the chance of developing new caries lesions of the subjects with moderate and high caries risk was 2.86 and 11.65 times more than those with low caries risk.Conclusion:MCAT com-bined with Cariogram can more efficiently predict new caries de-velopment in 3-year-old children.

Objective:To analyze the efficacy and feasibility of performing a new surgical procedure, tunnel esophagogastrostomy, to perform proximal gastrectomy.Methods:The study cohort comprised 10 consecutive patients who had undergone esophagogastrostomy by the tunnel technique in Jiangsu Cancer Hospital between October 2019 and July 2022. All patients were male. Their average age was (64.2±8.1) years and body mass index (25.5±3.2) kg/m2. Nine had upper gastric body adenocarcinoma, the remaining one having signet ring cell carcinoma. TNM staging of the tumors showed that seven were Stage IA, one Stage IB, one Stage IIA, and one Stage IIIA. Briefly, tunnel esophagogastrostomy is performed as follows: After performing a proximal gastrectomy, a rectangular seromuscular flap (3.0 cm × 3.5 cm) is created. The posterior esophageal wall is sutured to the gastric wall at the orad end of the seromuscular flap 5 cm from the stump with three to four stitches. Next, the stump of the esophagus is opened, the posterior esophageal wall is sutured to the gastric mucosa and submucosa, and the anterior esophageal wall is sutured to the full layer of the stomach. Finally, the caudad end of the seromuscular flap is closed. Data on surgical safety, postoperative morbidity, and postoperative reflux esophagitis were analyzed. All enrolled patients completed endoscopic follow-up 1 year and 2 years after surgery.Results:All procedures were completed. They comprised four cases of laparoscopic assisted surgery, four of DaVinci robotic surgery, and two of open surgery. The mean operation time was 212.7±33.2 mins, mean anastomosis time (51.6±5.3) minutes, mean tunnel preparation time (20.0±3.5) minutes, and mean operative blood loss (90.0±51.6) mL. The time to first postoperative passage of flatus was (64.8±11.5) hours. The mean hospital stay after surgery was (9.2±1.7) days. There were no postoperative complications above Clavien-Dindo Grade II. The mean preoperative Reflux Disease Questionnaire score was (3.3± 0.4) before the surgery, (3.8±1.0) 1 month postoperatively, and (3.3±0.4) 12 months postoperatively. All patients underwent endoscopic follow-up; no anastomotic stenoses were found. However, one patient had Grade A reflux esophagitis 1 year after surgery and another Grade B reflux esophagitis 2 years after surgery.Conclusion:Esophagogastrostomy by the tunnel technique is a safe and feasible means of performing proximal gastrectomy.

Objective:To analyze clinical characteristics and genetic characteristics of children with ATP sensitive potassium passage (K ATP-HI). Methods:Forty-five children with genetically confirmed K ATP-HI and their families admitted to Beijing Children′s Hospital of Capital Medical University between February 2002 and December 2018 were selected as the study subjects. A detailed retrospective analysis of the patient's clinical characteristics, diagnosis and treatment process, disease-causing gene carrying status and later follow-up data was performed. ABCC8/KCNJ11 gene was sequenced by second-generation sequencing technology. Results:Among 45 children with K ATP-HI, 34 cases (75.6%) were neonatal onset, the first symptoms of 21 cases (46.7%) were convulsions. 39 cases had been treated with diazoxide, including 12 cases (30.8%) with good efficacy, 16 cases (41%) with poor efficacy and 11 cases with uncertain efficacy. Octreotide was further applied in 18 patients with uncertain or ineffective efficacy after diazoxide treatment, and 13 cases (72.2%) were effective, 3 cases were ineffective, and 2 cases were uncertain. 10 CHI patients who were ineffective to drug treatment or had clearly focal lesions confirmed by 18F-dopa positron emission by computed tomography ( 18F-DOPA PET) scans had undergone surgical treatment, 8 of which underwent partial pancreatectomy and blood glucose returned to normal after the operation; the other 2 cases underwent subtotal pancreatectomy and both had secondary diabetes after operation. Among 45 children with K ATP-HI, 1 case carried both ABCC8 and KCNJ11 mutations, 10 cases carried ABCC8 compound heterozygous mutations, and the remaining 34 cases carried ABCC8/KCNJ11 single genetic mutation. Among them, 21 cases had paternal inheritance, and 3 cases had maternal inheritance, 6 cases were identified with de novo mutations. Conclusions:Diazoxide treatment was ineffective for most K ATP-HI children, but octreotide had a higher effective rate. Partial pancreatectomy for focal type patients had a higher cure rate, and there was a risk of secondary diabetes after subproximal pancreatectomy, so it was very important to clarify the histological type of children before surgery. ABCC8 gene mutations and KCNJ11 gene mutations were the main pathogenic genes of K ATP-HI. Among patients carrying mutations in single ABCC8 or KCNJ11 gene mutation, K ATP-HI inherited by paternity were the majority. Some K ATP-HI children can relieve the hypoglycemia symptoms by themselves.

A male patient aged 1 year and 8 months with type 2 spondyloepimetaphyseal dysplasia with joint laxity (SEMDJL2) was reported. The clinical characteristics included short stature, flat middle face, hypotonia, limb joint relaxation, hyperextension of metacarpophalangeal articulation, etc. In addition, the patient had a history of congenital laryngeal stridor. Thus, SEMDJL2 was determined according to the above symptoms and medical history. Sanger sequencing showed that the child carried a c.443C>T missense mutation in the KIF22 gene, which resulted in an amino acid variation namely p.Pro148Leu. This phenotype was preliminarily determined as a pathogenic mutation. Therefore, it is suggested that next-generation sequencing genetic testing could be helpful for genetic diagnosis in children with congenital laryngeal stridor, systemic joint relaxation, and excessive joint extension.

Objective:To study the clinical and genetic characteristics of Gitelman syndrome in children.Methods:Four children diagnosed with Gitelman syndrome in the Baoding Children′s Hospital from January 2017 to October 2018 were enrolled, and their clinical data and pathogenic gene carrying status were analyzed.Results:There were 2 males and 2 females in the enrolled patients.Two children complained of short stature and 2 children were diagnosed as hypokalemia by accident.All the 4 children showed constipation, short stature, repeated hypokalemia, hyponatremia, hypochloremia, normal urinary calcium/creatinine ratio, elevated renin and angiotensin Ⅱ levels in supine position, and normal aldosterone.Three children had hypomagnesemia and 1 child had a normal blood magnesium level.All of the 4 children had a compound heterozygous mutation of SLC12A3 gene.The mutations of c. 1670-7G>A and c. 1698C>A were not reported in the literature. Conclusions:Constipation and short stature are common clinical manifestations of Gitelman syndrome in children.Typical cases show hypokalemia, hypomagnesemia, hyponatremia and hypochloremia, etc.The blood magnesium level can be normal in few children.Most children with Gitelman syndrome carry SLC12A3 compound heterozygous mutations.

Objective:To construct nursing quality evaluation indicator system for comprehensive stroke center, so as to provide reference for standardized nursing quality evaluation of comprehensive stroke center.Methods:From September 2018 to December 2019, based on the theory of Donabedian′s structure-process-outcome quality model, literature review, semi-structured interview, Delphi method and analytic hierarchy process were used to determine nursing quality evaluation index system and index weight for comprehensive stroke center.Results:A total of 16 experts from comprehensive stroke center were consulted for two rounds. The clinical working time was 24.63±10.08 years, and the effective recovery rates of two rounds were 100%. The authority coefficient of experts was 0.888, and the coordination coefficients W of two rounds were 0.229 and 0.283 respectively.Finally, a nursing quality evaluation indicator system for comprehensive stroke center was constructed, including 3 first-level indicators, 13 second-level indicators and 46 third-level indicators. Conclusions:The established nursing quality evaluation indicator system for comprehensive stroke center covers the whole process of stroke emergency, stroke unit, and follow-up, which is scientific and reliable, and provides an evaluation tool for daily nursing quality monitoring and continuous quality improvement in comprehensive stroke centers.

Objective To understand the nutrition status in elderly patients with hip fracture, and clarify its effects on postoperative functional recovery,complications and mortality based on literature analysis of the past 10 years. Methods PubMed,Medline,Embase Database,Wanfang Database,Chinese National Knowledge Infrastructure(CNKI)and China Biology Medicine disc(CBMdisc)were searched,and relevant researches published from 1st January,2010 to 31th May,2019 were collected. Single rate Meta-analysis was used to integrate the prevalence and mortality of malnutrition. A qualitative systematic review was used to analyze the relationship between nutritional status and prognosis after surgery. Results A total of 11 articles was included,including 21791 patients. Meta-analysis showed that the mean prevalence of malnutrition during hospitalization in elderly patients with hip fracture was 46％(95％CI:45％-47％)using serum albumin(ALB),and was 17％(95％CI:12％-22％)assessing by the Mini Nutritional Assessment (MNA),and the risk of malnutrition prevalence was 42％(95％CI:45％-47％). The results of qualitative evaluation showed that compared with the well-nutrition group(Short-form MNA 12-14 points),the malnutrition risk group(Short-form MNA 8-11 points)had lower activity ability 4 months after the operation (OR=2.03,95％CI:1.24-3.31),and the MNA score decreased by 1 point,the risk of death increased by 15％(HR=0.869,95％CI:0.757-0.998). The malnutrition group(ALB<3.5 g/dl)had a higher incidence of sepsis (P< 0.001)and pulmonary infection(P=0.019),with every 1 g/dl reduction in ALB and 0.59-fold increased risk of death(RR=0.59,95％CI:0.53-0.65). Conclusions The incidence of hip fracture malnutrition or malnutrition risk is very high in the elderly patients with hip fracture. Both malnutrition and malnutrition risk have negative effects on postoperative functional recovery,complications and death rates,and the worse the nutritional status,the worse the prognosis. So,both ALB and MNA are recommended to be included in the care plan of elderly patients with hip fracture. When ALB is failed to diagnose malnutrition,the MNA evaluation method should be adopted to find the problems of nutrition and offer nutritional intervention in advance.
