Abstract Recent years have witnessed more attention paid to the health effects of the natural radionuclide 226Ra, and a series of research carried out on the detection methods of 226Ra at home and abroad. The common 226Ra detection methods are emanation scintillation, gamma spectrometry, liquid scintillation counting, alpha spectrometry and alpha counting. Emanation scintillation is mature enough as a classical method, while gamma spectrometry and liquid scintillation counting proceed fast. Due to the radiation of 226Ra, these detection methods still have the problems such as the requirement for large samples, long detection periods, complicated steps, high detection limits and low recovery rates. This paper reviews the five methods above and summarize their advantages and disadvantages, so as to provide the reference for selecting and optimizing the detection methods for different samples as well as perfecting the standard method in China.

Objective To explore the diagnostic value of endoscopic ultrasonography(EUS)for the minimal submucosal invasion of early gastrointestinal tumor. Methods A total of 242 patients with early gastrointestinal tumor,who underwent endoscopic submucosal dissection,were retrospectively analyzed. The accuracy of EUS diagnosis was calculated based on postoperative histopathological findings as the golden standard,and influencing factors were also analyzed. Results Overall diagnostic accuracy of EUS for sub-mucosal invasion of early gastrointestinal tumors was 72. 3%(175/ 242),with an overstaging rate of 21. 5%(52/ 242)and an understaging rate of 6. 2%(15/ 242).Tumor size(P = 0. 018)and location(P = 0. 005) had significant effects on the diagnostic accuracy of the minimal submucosal invasion of early gastrointestinal tumor by EUS. The overstaging rate in the lesion length of diameter>3 cm was higher than those of 3 cm or less[27. 0%(33/ 122)VS 15. 8%(19/ 120),P = 0. 807],the overstaging rates of early colonrectal and gastric cancer were also significantly higher than the understaging rate[ Colonrectum:12. 2%(9/ 74)VS 2. 7%(2/ 74),P= 0. 028;Stomach:26. 9%(28/ 104)VS 2. 9%(3/ 104),P = 0. 000]. Conclusion Endoscopic ultrasonography is of diagnostic value for the invasion depth of early cancer in gastrointestinal tract. However,precaution should be taken in large lesions and the tendency of overstaging in gastrointestinal tract.

OBJECTIVETo investigate the effect of hyperglycemia within postoperative 48 hours on gastrointestinal (GI) fistula patients without preoperative diagnosis of diabetes undergoing selective GI reconstruction.

METHODSClinical data of GI fistula patients with age of 18 to 70 years and without diffuse peritonitis and systemic infection undergoing definitive GI reconstruction at Intestinal Fistula Center of Jinling Hospital from September 2012 to December 2015 were retrospectively analyzed. According to the highest blood glucose (BG) value detected within postoperative 48 hours, patients were divided into normoglycemia (BG<6.9 mmol/L), mild hyperglycemia (6.9 to 11.4 mmol/L) and severe hyperglycemia (BG≥11.5 mmol/L) groups. Clinical manifestations were compared among three groups. Effects of postoperative hyperglycemia on associated parameters, including postoperative surgical site infection, anastomotic leakage, intestinal nutrition recovery, hospital stay and hospitalization cost were investigated.

RESULTSA total of 314 patients were enrolled, of whom postoperative gastric fistula occurred in 6 cases, small intestinal fistula in 95 cases, ileocolonic anastomotic fistula in 116, and colorectal fistula in 97 cases. One hundred and ninety-three (61.5%) patients experienced hyperglycemia, including 148 cases of mild hyperglycemia group and 45 cases of severe hyperglycemia group, the other 121 cases were of normoglycemia group. There were no significant differences in gender, BMI, ratio of smoking, ratio of alcohol user and primary diseases among 3 groups (all P>0.05). Older patients were vulnerable to postoperative hyperglycemia and patients who developed hyperglycemia were also prone to have increased ASA score (all P=0.000). Hyperglycemia patients had significantly higher ratio of postoperative ileocolonic anastomotic fistula (mild hyperglycemia group: 40.5%, 60/148; severe hyperglycemia group: 44.4%, 20/45) than normoglycemia cases (29.8%,36/121). Compared to normoglycemia group, ratio of intra-operative transfusion case was higher (P=0.001), operative time was longer (P=0.026), ratio of number of anastomosis >2 was higher (P=0.001), ratio of receiving laparoscopic-assisted operation was lower (P=0.005), ratio of postoperative surgical site infection was higher (P=0.006), incidence of anastomotic leakage was higher (P=0.004), ratio of re-operation was higher (P=0.004), intestinal nutrition recovery time was longer (P=0.001), ICU stay was longer (P=0.001), total hospitalization time was longer (P=0.000) and hospitalization cost was more expensive (P=0.000) in both two hyperglycemia groups. Multivariate regression analysis showed that mild hyperglycemia and severe hyperglycemia were independent risk factors to predict surgical site infection (OR=1.99, 95%CI: 1.12 to 3.54, P=0.019; OR=3.02, 95%CI: 1.36 to 6.70, P=0.007) and anastomotic leakage (OR=7.59, 95%CI: 1.68 to 34.34, P=0.009; OR=13.4, 95%CI: 2.50 to 71.65, P=0.002). Multivariate linear regression analysis indicated that intestinal recovery time of normoglycemia group was 2 days shorter and 3 days shorter, and hospitalization time of normoglycemia group was 2 days shorter and 10 days shorter as compared with mild hyperglycemia and severe hyperglycemia group, respectively.

CONCLUSIONSElevated postoperative BG is common in GI fistula patients receiving selective GI reconstruction. Postoperative hyperglycemia is significantly associated with surgical site infection, anastomotic leakage and prolonged intestinal recovery. BG control treatment should be recommended for those patients with postoperative hyperglycemia.

Objective To learn the effects of family supportive supervisors on medical staff turnover intention. Methods The scales of family supportive supervisor behavior scales, work-family conflict scale and turnover intention scale were used in the study. The data were collected from a questionnaire survey of 214 army tertiary hospitals′ medical staff during October to December 2017. Hierarchical regression analysis was used to establish a model to understand the influence of family supportive supervisor behavior, two-way conflict between work and family, using the independent variables, on turnover intention of medical staff. Results The and family supportive supervisor behaviors had a negative explanation to medical staff turnover intention ( β = - 0. 211, P < 0. 01), work interference with family had a positive explanation to it (β = 0. 358, P < 0. 01), family interference with work had an obscure explanation to medical staff turnover intention (β = 0. 104, P > 0. 05). Work interference with family had a partially mediating effect which influenced family supportive supervisor behaviors on medical staff turnover intention. Conclusions Family supportive supervisor behavior, as an organizational support, can effectively alleviate the work interference on family for medical staff and thus minimize their turnover intention.

Objective: To explore the relationship between childhood abuse, adult attachment and borderline personality disorder (BPD) in college students, and to provide reference for promoting the physical and mental health of college students. Methods: We selected undergraduate students from four colleges in Hefei, a total of 4 034 college students were surveyed by the childhood trauma questionnaire short form(CTQ-SF), the state adult attachment measure (SAAM) and the Personality Diagnostic Questionnaire(PDQ). Results: BPD was found in 4.2% of subjects, 4.5% of males and 3.7% of females. The score of BPD in non-single-parent families was lower than that in single-parent families, in families with average family economic status was lower than that in families with poor and good family economic status, and in families with medium father education level was lower than that in fathers with low and high education level(Z=-2.30, 29.25, 9.63, P<0.05). Childhood abuse, avoidant attachment and anxious attachment positively predicted BPD(β=0.21, 0.10, 0.23, P<0.01), secure attachment negatively predicted BPD(β=-0.15, P<0.01). Adult attachment played a partial mediating role in the effects of childhood abuse on BPD, with the mediating effect accounting for 16.7% of the total effect. Conclusion Adult attachment plays a mediating role in the effects of childhood abuse on BPD.

Objective: To investigate the prevalence of witnessing domestic violence,and to explore the relationship between witness domestic violence in childhood and college students’ injury and violence behaviors. Methods: In October 2018, self-made questionnaire on “Health and Risky Behaviors among University Students in Anhui Province” was conducted among 4 034 college students from 4 universities in Hefei. Multivariate Logistic regression models (control of confounding factors) were used to explore the impact of childhood witnessing domestic violence on college students’ injury and violence. Results: Among 4 034 college students,the prevalence of witnessing domestic emotional violence,mild physical violence and severe physical violence in childhood was 27.6%,22.4%,10.7%,respectively. Univariate analysis showed that students with experiences of witness domestic emotional violence,mild physical violence and severe physical violence had higher rates of self-injury,physical,emotional,and sexual violence compared to those without domestic violence witness(P<0.05). Multivariate Logistic regression analysis showed that witnessing domestic severe physical violence,emotional violence in childhood associated positively with self-harm (OR=1.53,95%CI=1.05-2.23; OR=2.15,95%CI=1.51-3.04) and emotional violence (OR=1.65,95%CI=1.16-2.35; OR=2.57,95%CI=1.87-3.53). Witnessing domestic severe physical violence showed positive association with physical violence (OR=4.99,95%CI=2.58-9.62) and sexual violence (OR=8.68,95%CI=3.30-22.81) among college students (P<0.05). Conclusion The experiences of witness domestic violence can increases the risk of college student’s injury and violence behaviors,especially witness domestic severe physical violence.

Objective:To investigate the clinical value of three-dimensional (3D) visualization technology in the precise drainage through endoscopic retrograde biliary drainage (ERBD) for hilar cholangiocarcinoma.Methods:Clinical data of 42 patients with highly suspected hilar cholangiocarcinoma who underwent ERBD in Qinghai University Affiliated Hospital from September 2019 to August 2022 were retrospectively collected. Twenty patients underwent 3D biliary tract reconstruction before surgery (the reconstruction group) and 22 others did not undergo 3D biliary tract reconstruction before surgery (the non-reconstruction group). The surgery time, X-ray exposure time, the technical success rate, the clinical success rate, incidence of postoperative complications, recent and short-term endoscopic retrograde cholangiopancreatography (ERCP) reintervention rate of the two groups were compared.Results:There was no significant difference in preoperative baseline data between the two groups ( P>0.05). ERBD was conducted successfully in all 42 patients. The operation time in the reconstruction group [35.00 (25.00, 57.50) min] was significantly shorter than that in the non-reconstruction group [60.00 (33.75, 60.00) min] with significant difference ( Z=-2.251, P=0.024). There was no significant difference in the X-ray exposure time between the two groups [10.00 (5.00, 12.00) min VS 10.55 (9.50, 17.50) min, Z=-1.552, P=0.121]. The technical success rates of both groups were 100.0%, and the clinical success rate of the reconstruction group was higher than that of the non-reconstruction group [70.0% (14/20) VS 31.8% (7/22)] with significant difference ( χ 2=6.109, P=0.013). There was no significant difference in the incidence of postoperative complications between the two groups [20.0% (4/20) VS 22.7% (5/22), χ 2=0.141, P=0.708]. All patients were followed up for 6 months after the procedure. The median survival time was 3.91 months in the reconstruction group and 2.78 months in the non-reconstruction group. There was no ERCP intervention in the reconstruction group within 2 weeks after the procedure, while 4 cases (18.2%) in the non-reconstruction group received 6 ERCP interventions due to cholangitis and postoperative pancreatitis. Within 2 weeks to 3 months, 2 patients (10.0%) in the reconstruction group received 4 ERCP interventions for cholangitis, and 2 patients (9.1%) in the non-reconstruction group received 3 ERCP interventions for cholangitis. There was no significant difference in recent ( χ 2=2.183, P=0.140) or short-term ( χ 2=0.000, P=1.000) ERCP reintervention rate between the reconstruction group and the non-reconstruction group. Conclusion:3D visualization biliary duct reconstruction technology can measure the volume of liver drainage for hilar cholangiocarcinoma, shorten the operation time and improve the clinical success rate through precise preoperative planning, which is worth of promotion.
