ABSTRACT
Objective@#To understand the association between sugar sweetened beverage consumption with physical fitness index among college students, so as to provide a reference for the improvement and intervention of college students physical fitness.@*Methods@#From September to December 2021, a total of 5 520 college students from universities in Jilin, Anhui, Jiangxi, Xinjiang, and Shanghai, were surveyed with sugar sweetened beverage consumption and physical fitness using stratified cluster sampling. One way ANOVA and Logistic regression analysis were used to analyze the association between sugary drink consumption and physical fitness index (PFI).@*Results@#The frequencies of sugar-sweetened beverage consumption among college students were 10.3% , 67.2%, 13.9% , and 8.6% for 0, 1-3, 4-5, and ≥ 6 times/week, respectively. The differences in waist circumference, grip strength, standing long jumping, sit and reach, 50-meter running, and 1 000/800 meter running performance were statistically significant among college students with varying sugar-sweetened beverage consumption ( F =8.67, 7.22, 11.20, 13.47, 3.98, 2.86 , P <0.05). Logistic regression analysis showed that those who had sugary drinks 4-5 times/week, ≥ 6 times/week had a higher risk of low PFI compared to those who reported no sugary drinks ( OR =1.48, 1.56, P <0.05). With respect to gender, the risk of low PFI was also higher among male students who consumed sugary drinks ≥6 times/week ( OR =2.01, P <0.05), while there was no significant difference among female students.@*Conclusion@#Sugar-sweetened beverage consumption is negatively associated with the physical fitness index among college students with significant gender differences. College students, especially males, should be targeted to improve health literacy, reduce the consumption of sugar-sweetened beverages, so as to improve physical fitness.
ABSTRACT
ObjectiveTo develop and validate a predictive risk model for vision-threatening diabetic retinopathy in patients with type 2 diabetes using readily accessible clinical data， which may provide a convenient and effective prediction tool for early identification and referral of at-risk populations. MethodsA nomogram model was developed using a dataset obtained from patients with T2DM who participated in the Guangzhou Diabetic Eye Study from November 2017 to December 2020. Logistic regression was used to construct the model， and model performance was evaluated using receiver operating characteristic curve， Hosmer-Lemeshow test， calibration curve and decision curve analysis. The model underwent internal validation through the mean AUC of k-fold cross-validation method， and further external validation was conducted in the Dongguan Eye Study. ResultsA total of 2 161 individuals were included in the model development dataset， of whom 135 （6.25%） people were diagnosed with VTDR. Age （P＜0.001，OR=0.927，95%CI：0.898~0.957） and body mass index （P＜0.001，OR =0.845，95%CI：0.821~0.932） were found to be negatively correlated with VTDR， whereas diabetes duration （P＜0.001，OR=1.064，95%CI：1.035~1.094）， insulin use （P =0.045，OR =1.534，95%CI：1.010~2.332）， systolic blood pressure （P＜0.001，OR =1.019，95%CI：1.008~1.029）， glycated hemoglobin （P＜0.001，OR =1.484，95%CI：1.341~1.643）， and serum creatinine （P＜0.001，OR =1.017，95%CI：1.010~1.023） were positively correlated with VTDR. All these variables were included in the model as predictors. The model showed strong discrimination in the development dataset with an area under the receiver operating characteristic curve （AUC） of 0.797 and in the external validation dataset （AUC 0.762）. The Hosmer-Lemeshow test（P＞0.05）and the calibration curve displayed good agreement. Decision curve analysis showed that the nomogram produced net benefit in the two datasets. ConclusionsIndependent factors influencing VTDR include age， duration of diabetes mellitus， insulin use， body mass index， systolic blood pressure， glycosylated hemoglobin， and serum creatinine. The nomogram constructed using these variables demonstrates a high degree of predictive validity. The model can serve as a valuable tool for early detection and referral of VTDR in primary care clinics. Therefore， its application and promotion are highly recommended.
ABSTRACT
OBJECTIVE@#To explore the association between postoperative C-reactive protein (CRP) levels and the occurrence of postoperative atrial fibrillation in patients undergoing cardiopulmonary bypass surgery.@*METHODS@#We retrospectively analyzed the data of 550 patients undergoing cardiopulmonary bypass surgery in our hospital from September, 2018 to May, 2021, and after screening against the exclusion criteria, 363 patients were selected for further analysis. Univariate analysis was used to analyze the correlation of age and early postoperative CRP level with the occurrence of postoperative atrial fibrillation, and Chi-square test was used to explore the correlation of gender, disease type, and comorbidity with postoperative atrial fibrillation followed by multivariate analysis of the data using a binary logistic regression model.@*RESULTS@#The 363 patients enrolled in this study included 247 with valvular disease, 42 with aortic dissection, 37 with coronary heart disease, and 37 with congenital heart disease, with a median postoperative CRP level of 88.65 mg/L and a median age of 57 years (range 5-77 years). Postoperative atrial fibrillation occurred in 101 (27.82%) of the patients, who were subsequently divided into atrial fibrillation group and sinus group. Univariate and multivariate correlation analyses showed that early postoperative elevation of CRP level was an important factor contributing to the occurrence of postoperative atrial fibrillation.@*CONCLUSION@#Early postoperative elevation of CRP level is associated with the occurrence of atrial fibrillation following cardiopulmonary bypass surgery.

ABSTRACT
BACKGROUND: To delay the further aggravation of early femoral head necrosis, drilling decompression of the femoral head is a better treatment method. However, traditional trepanation and decompression of the femoral head is traumatic. OBJECTIVE: To compare the difference in the effect between robot-assisted drilling decompression and traditional surgery for aseptic necrosis of femoral head. METHODS: Forty patients with aseptic necrosis of the femoral head were included for retrospective comparative analysis. According to the treatment plan, they were divided into two groups. Eighteen cases (26 femoral heads) in the robot group were treated with drilling decompression assisted by robots. Among them, 13 cases (18 femoral heads) were in Ficat stage I and 5 cases (8 femoral heads) were in Ficat stage II. The traditional surgery group consisted of 22 patients (29 femoral heads). Among them, 15 patients (19 femoral heads) were in Ficat stage I and 7 patients (10 femoral heads) in Ficat stage II. Incision, times of intraoperative fluoroscopy, intraoperative blood loss, times of intraoperative puncture and operation time were compared between the two groups. Harris score was used before and 1, 3, and 6 months after operation to evaluate the hip effect. RESULTS AND CONCLUSION: (1) All cases were followed up for 6 months. (2) Incision, times of intraoperative fluoroscopy, intraoperative blood loss, times of intraoperative puncture and operation time were better in the robot group than in the traditional surgery group (P 0.05). (4) Compared with the traditional surgery, robot-assisted drilling decompression has no obvious advantage in the treatment of aseptic necrosis of the femoral head. However, its operation incision is small; the number of intraoperative fluoroscopy is small; the trauma is small; and the operation is safer and minimally invasive.
ABSTRACT
Objective:To investigate the levels of gross radioactivity in drinking water and of 90Sr in food around Sanmen nuclear power plant (NPP) before and after operation. Methods:From 2012 to 2019, 7 drinking water monitoring sites were selected around the Sanmen NPP to collect source water, factory water and peripheral water, respectively, in order to measure and analyze the total radioactivity level in drinking water. Based on the dietary habits of local residents, 4 kinds of food such as grains, vegetables, freshwater fish and marine fish grown locally were sampled to measure and analyze the activity concentration of 90Sr. Results:Before the operation of Sanmen NPP, the total α radioactivity and total β radioactivity in drinking water around the NPP were 0.001-0.063 Bq/L and 0.019-0.210 Bq/L, respectively. After operation, the total α radioactivity and total β radioactivity were 0.001-0.084 Bq/L and 0.025-0.079 Bq/L, respectively. Both were lower than the national standard value given in the GB 5749-2006 " Sanitary standards for drinking water" . There was no significant change in the radioactivity level of source water, factory water and peripheral water during the wet and dry periods. The activity concentration of 90Sr in these four types of food ranged from 0.037 to 1.216 Bq/kg before operation and from 0.049 to 0.692 Bq/kg after operation, all lower than the standard value of " Standard for the concentration in radioactive substances in food" (GB 14882-94). Conclusions:Before and after the operation of Sanmen NPP, the total α and total β radioactivity in drinking water and 90Sr activity concentration in food are stable, below the national standard limit.
ABSTRACT
Emotional disorder is one of the main clinical symptoms of autism spectrum disorder(ASD),which is related to the lack of emotional awareness,social cognition and alexithymia. It is often manifested as difficulty in recognizing,distinguishing and processing emotional information of oneself and others,resulting in making inappropriate emotional reactions. Children and adolescents with ASD often participate in school bullying as the perpetrator,victim,or victim-perpetrator,and this brings about a series of negative physical and mental effects on them. Bullying prevention should not only include interventions for core symptoms and comorbidities of ASD,but also involve building partner empathy and social skills,teacher responsibility and supportive services,parental involvement,and social integration.
ABSTRACT
Objective To study the vascular anatomy of duplex kidney and to provide a scientific basis for surgical resection of the renal segment.Methods From February 2012 to April 2018,the clinical data of 84 children with renal duplex kidney disease admitted to our hospital,were reviewed and analyzed.Among them,75 cases (89.3％) were unilateral and 9 cases (10.7％) were bilateral.According to the preoperative CT + CTA and the duplicated renal morphology,size,location,and anatomical relationship of the kidney segment,combined with the branches and passage of the renal artery which supplies the upper moiety,it described the blood supply of the upper renal moiety.At the same time,it analyzed various types of embryological related factors and gender differences and summarized the tips for laparoscopic surgery.Results Of the 93 duplex kidneys,69 (74.2％) were supplied with 1 artery,and 25 (26.9％) were supplied with 2 or more arteries.Based on the shape and orifice of artery,they were divided into 3 types.The most common type was that the renal artery separated into two or more arteries near the renal parenchyma.The upper and lower renal poles were respectively supplied,which could be summarized as early branching,a total of 71 sides (76.3 ％).The second type was the arteries from abdominal aorta or its branches,directly flowing into the upper renal pole,which was classified into the sub-renal artery,a total of 18 sides (19.4％).The others (4 sides,3.3％) were less common,and most of them were a combination of the above-mentioned two types,and one of them whose upper pole was supplied by branches of adrenal artery.Based on the classification of vascular variability,no significant difference was found between males and fenmals,or left and right sides.Conclusions The upper renal moiety are mainly supplied by one branch of renal artery,and the most common type of this artery is prehilar branch,without gender difference.The determination of vascular variability before surgery can avoid bleeding during surgery and avoid accidental injury of normal blood vessels.
ABSTRACT

ABSTRACT
To evaluate the bone strength and structure of patients with obstructive sleep apnea(OSA)by the high-resolution peripheral quantitative computed tomography(HR-pQCT)and to explore the relationship between OSA and osteoporosis. Male patients who visited the Sleep Respiratory Center of our hospital from August 2017 to January 2019 were consecutively recruited.Clinical data including the results of Epworth sleep scale(ESS)scoring and overnight polysomnography were collected.HR-pQCT was used to compare the differences in bone geometry,density,and microstructure between OSA patients and non-OSA people;also,the radius and tibia on the non-dominant side were measured to explore the relationship between OSA and osteoporosis. A total of 83 subjects were enrolled in the study.The number of patients in the mild,moderate,and severe OSA groups and non-OSA group were 21,18,34,and 10,respectively.There was no significant difference in age,blood pressure,ESS score,sleep stage,and sleep efficiency among these four groups(>0.05).Body mass index(BMI)and neck circumference were significantly different among these groups(=4.234,=0.008;=3.100,=0.031).There was no significant difference in the radius indicators(>0.05).For tibia,there were significant differences among the four groups in the cortical area(Ct.Ar)(=3.937,=0.011).There were also significant differences in the bone microstructural indicators including trabecular thickness(Tb.Th)and cortical thickness(Ct.Th)(=6.247,=0.001;=3.746,=0.014),which were significantly lower in the three OSA groups than in the control group.Pairwise comparisons showed that the Ct.Ar in the severe OSA group was significantly higher than that in the mild OSA group(=0.019)and Tb.Th in the control group was significantly higher than those in the mild and moderate OSA groups(=0.006,=0.001).Correlation analysis showed that,within a certain range,total volumetric bone mineral density(Tt.vBMD)and Tb.Th of radius and tibia were negatively correlated with age(=-0.312,=0.004;=-0.328,=0.002;=-0.265,=0.015;=-0.280,=0.010)and positively correlated with BMI(=0.240,=0.029;=0.369,=0.004;=0.299,=0.006;=0.416,=0.010).Stepwise multiple regression analysis showed that Tb.Th of radius and tibia were mostly correlated with BMI(=0.262,=0.008,=0.243,=6.270,=0.000;=0.494,=0.000,=0.186,=7.243,=0.000)and age(=-0.216,=0.030,=0.243,=6.270,=0.000;=-0.306,=0.003,=0.186,=7.243,=0.000).Tt.vBMD of radius had a certain correlation with sleep efficiency and with the decreasing nocturnal mean oxygen saturation caused by OSA(=0.312,=0.002, =-0.249,=0.012,=0.327,=7.482,=0.000). In non-elderly male populations,OSA mainly causes a decrease in Tb.Th and Ct.Th of the tibia.The changes in bone strength and structure are mainly related with age and body size and also have certain correlations with sleep efficiency and with the decreasing nocturnal mean oxygen saturation caused by OSA.

ABSTRACT
An online solid phase extraction ( online-SPE) combined with ultra high performance liquid chromatography-quadrupole linear ion trap mass spectrometry (UHPLC-MS / MS-Qtrap) was established for the simultaneous identification and determination of 10 kinds of algal toxins in water samples. Multiple injections of water samples were controlled by a preset program, and the target analytes were enriched by trap column. The six-way valve was switched subsequently, and the algal toxins in the trap column were back-flushed to the analytical column for separation and analysis. The results showed that the online SPE significantly simplified pretreatment process, and the linear ion trap tandem mass spectrometry improved the sensitivity of the determination. Moreover, the establishment of enhanced product ion (EPI) scan library provided evidence for the confirmation of algal toxins. The 10 kinds of algal toxins showed a good linear relationship with correlation coefficient R2>0. 99. The limits of detection (LOD) were 0. 0015 -0. 0050 μg / L. The mean recoveries at three spiked levels of 0. 02, 0. 1, 1. 0 μg / L were from 83. 7% to 98. 5% . The method was suitable for the rapid confirmation and quantitative determination of various algal toxins in water.

ABSTRACT
BACKGROUND:Studies have shown that percutaneous pedicle screw internal fixation in repair of single segment of thoracolumbar fracture can overcome quadrilateral effect, get better biomechanical properties, meanwhile, it also can provide three-point fixation, reduce suspension effect, and reduce the formation of kyphosis. OBJECTIVE: To investigate the clinical efficacy and incidence of complications of the percutaneous pedicle screw internal fixation for treatment of single segment thoracolumbar fractures. METHODS:Totaly 36 patients with single segment thoracolumbar fractures treated by percutaneous pedicle screw internal fixation were enroled. A total of 36 vertebral bodies were treated: T11=5, T12=8, L1=17, L2=6. The visual analog scale scores before treatment and at 3, 6 and 12 months after treatment, the Oswestry disability indexes before treatment, at the first week and at the 12th month after treatment, the Cobb angle before treatment, the first day and at the 12th month after treatment were compared and observed. The incidence of complications was recorded. RESULTS AND CONCLUSION:The visual analog scale scores at 3, 6 and 12 months after treatment was significantly lower than those before treatment (P < 0.001). The Oswestry disability indexes before treatment, at the first week and at the 12th month after treatment were significantly lower those that before treatment (P < 0.001).The Cobb angle before treatment, at the first day and at the 12th month after treatment was significantly smaler than that before treatment (P < 0.001). Only three (8%) patients had complications, including pedicle screw penetrating pedicle into the spinal canal, pedicle screws loosing and the infection in puncture site. These results suggest that percutaneous pedicle screw internal fixation for treatment of single segment thoracolumbar fractures can correct kyphosis, improve the thoracolumbar motion, quickly relieve patient’s back pain, and the incidence of complications is low.
