Objective To measure the maximum movement of the hyoid bone and ventriculus laryngis during normal swallowing. Methods Forty volunteers were selected as subjects, and an X?ray simulator was used to collect the videos of normal swallowing. Video analysis software was used to capture continuous and quick screenshots of these videos, and the maximum movement of the hyoid bone and ventriculus laryngis was measured. The difference in movement was analyzed by one?way analysis of variance. Results The mean time for swallowing in 40 volunteers was 1.13±0.28 s. During the process of swallowing, the hyoid bone and ventriculus laryngis moved upward first, then outward, and finally returned to the resting position. The maximum movement of the hyoid bone forward and backward was 0.90±0.30 cm;the maximum vertical movement of the hyoid bone was 0.93±0.36 cm. The maximum movement of the ventriculus laryngis forward and backward was 0.69± 0. 25 cm;the maximum vertical movement of the ventriculus laryngis was 1.04±0.45 cm. Further studies showed the effect of age on the time for swallowing (P=0.03), with similar results for the male and female ( P=0.13) . Sex and age had no effects on movement of the hyoid bone and ventriculus laryngis (P=0.28?0.81 and 0.20?0.88). Conclusions During normal swallowing, the hyoid bone and the ventriculus laryngis move first upward and then forward. These movements should be considered during the development of radiotherapy plan for head and neck cancer.

Objective To compare diagnostic value of ~(18)F-fluoredeoxyglucose (FDG) PET/CT with contrast-enhanced CT in detecting primary hepatic carcinoma and postoperative recurrence.Methods Twenty-five cases of primary hepatic carcinoma or postoperative recurrent tumor underwent whole-body ~(18)F-FDG PET/CT and contrast-enhanced CT within one week's interval.They were retrospectively reviewed and the difierences between these two modalities were investigated.Results Of these 25 cases,there were 13 cases with primary hepatocellular carcinoma.1 case with intrahepatic cholangiocarcinoma and 11 cases with postoperative recurrence.The sensitivity of 18 F-FDG PET/CT and contrast-enhanced CT in diagnosing primary hepatic carcinoma was 78.6%(11/14) and 92.9%(13/14),and sensitivity in diagnosing postoperative recurrent was 100.0%(11/11) and 63.6%(7/11) respectively.Conclusion Contrast-enhanced CT may have a slight advantage over PET/CT in detecting primary hepatic carcinoma,but ~(18)F-FDG PET/CT combined with contrast-enhanced CT has even greater accuracy.Meanwhile,~(18)F-FDG PET/CT has better diagnostic accuracy in detection of postoperative recurrent tumor.

BACKGROUND: There has been an increasing trend of nut allergies in Singapore. OBJECTIVE: The aim of this study was to review the clinical characteristics of children with cashew nut allergy. METHODS: A retrospective analysis was conducted in a tertiary paediatric referral centre in Singapore from 2008 to 2015. A total of 99 subjects with positive specific IgE (≥0.35 IU/L) to cashew nut were identified. Clinical features including demographics, clinical reaction to cashew nut, associations with other nuts and test specific measurements were recorded. RESULTS: The results showed that cutaneous symptoms (71.2%) were the most common allergic manifestations. Anaphylaxis occurred in 3.8% of children. In addition, all cashew nut allergic subjects were cross-reactive (either sensitized or allergic) to pistachio. Cross-reactivity rate with peanuts was 53.8%. There was a strong prevalence of atopy among cashew nut allergic subjects. CONCLUSION: In conclusion, cashew nut allergy is a significant tree nut allergy in Singapore.

OBJECTIVETo describe the status of nutrition and health related indices in the Chinese population.

METHODSA stratified multi-stage cluster sampling was used from 31 provinces, autonomous regions, and municipalities. The survey was done in 2002, including data gathered from questionnaires, interviews, physical examinations, measurement of biochemical indices, and dietary investigation.

RESULTSCereals accounted for 48.5% of all the sources of energy in urban and 61.4% in rural populations. Daily mean percentages of calories for total fat were 35.0% in urban and 27.5% in rural areas. The prevalence rates of stunting and underweight were 14.3% and 7.8% respectively in young children under 5-year-old. The prevalence of vitamin A deficiency was 9.3% in Chinese children aged 3-12 years old. The total prevalence of anemia was 15.2% in general population of all ages. The prevalence of anemia in young adults was significantly higher in women than in men. The total prevalence rates of overweight and obesity were 17.6% and 5.6%, respectively. The prevalence rates of hypertension, diabetes, hypercholesteremia, hypertriglyceridemia, or low serum high density lipoprotein cholesterol were 18.8%, 2.6%, 2.9%, 11.9%, 7.4% respectively in Chinese adults aged 18 and over. The rates of awareness, treatment, and under control among hypertensives were 30.2%, 24.7%, and 25.0%, respectively. Significant regional and age differences were revealed in the dietary habit and the prevalence of various diseases. The prevalence of diseases associated with malnutrition were higher in rural than in urban areas. In contrast, the prevalence of conditions associated with overconsumption and inappropriate dietary patterns were higher in urban than in rural populations.

CONCLUSIONChinese people were currently suffering from both problems on nutrition related issues and burdens of diseases which were characterized in nutrient deficiencies and overconsumption, malnutrition and noncommunicable conditions associated with overconsumption and inappropriate diet. The difference of nutrition and health status between rural and urban people was also seen.

Objective:To better understand the pathogenesis of obstructive jaundice (O J),a variety of rat OJ and biliary drainage models have been tried;however,complications are still common.We aimed to establish a stable rat model of OJ using microsurgical techniques,and to assess its reversal by internal bile drainage(IBD).Methods:After the pilot study,we developed a standardized surgical procedure.All operations were carried out under an operating microscope.In the first laparotomy,the proximal common bile duct (CBD) of the rat was ligated and transected.A tube was introduced into the distal end of the duct,and the other end of the tube was sealed and fixed.In the second laparotomy,the drainage tube was inserted into the (by now markedly dilated) proximal CBD,and ligated into position.We evaluated the general condition of the rats,the status of the liver and pancreas before and after IBD.Results:Complications such as intestinal reflux and bile duct blockage,were not found.Pancreatic injury was not evident by day 4 after the first laparotomy.After biliary drainage,the serum glucose and albumin concentration rapidly returned to normal levels.Liver weight/body weight ratio increased.The biochemical indicators and ultrasonographic elastography results for the liver gradually returned to normal.Conclusion:Using microsurgical techniques,we have developed a stable rat model of OJ reversed by IBD.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

Background: Secondary preventive therapies play a key role in the prevention of adverse outcomes after coronary artery bypass grafting (CABG). However, medication adherence after CABG is often poor, and conventional interventions for improving adherence have limited success. With increasing penetration of smartphones, health-related smartphone applications might provide an opportunity to improve adherence. Carefully designed trials are needed to provide reliable evidence for the use of these applications in patients after CABG. Methods: The Measurement and Improvement Studies of Surgical Coronary Revascularization: Medication Adherence (MISSION-2) study is a multicenter randomized controlled trial, aiming to randomize 1000 CABG patients to the intervention or control groups in a 1:1 ratio. We developed the multifaceted, patient-centered, smartphone-based Heart Health Application to encourage medication adherence in the intervention group through a health self-management program initiated during hospital admission for CABG. The application integrated daily scheduled reminders to take the discharge medications, cardiac educational materials, a dynamic dashboard to review cardiovascular risk factors and secondary prevention targets, and weekly questionnaires with interactive feedback. The primary outcome was secondary preventive medication adherence measured by the Chinese version of the 8-item Morisky Medication Adherence Scale at 6 months after randomization. Secondary outcomes included all-cause death, cardiovascular rehospitalization, and a composite of death, myocardial infarction, stroke, and repeat revascularization. Discussion: Findings will not only provide evidence regarding the feasibility and effectiveness of the described intervention for improving adherence to CABG secondary preventive therapies but also explore a model for outpatient health self-management that could be translated to various chronic diseases and widely disseminated across resource-limited settings.
