Objective To obtain Hangzhou residents' awareness, understanding, demands, and intentions of health examination and explore the factors influencing health examination. Methods Totally 1 183 residents (male: 542, female: 641, aged from15 to 80 years) were investigated by mean of questionnaire which included demographic characteristics, health status, medical behavior and awareness, the subjective reasons of unwilling to take health examination, the intention of choosing an institution, and the data of questionnaire were analyzed using single factor Chi-square test and conditional logistic regression analysis. Results Single factor Chi-square test showed that the factors affecting health examination participation which have statistical significances were as follows, gender (χ2=11.61,P=0.000), age (χ2=9.09, P=0.028), residence registration (χ2=44.16,P=0.000), marital status (χ2=8.96,P=0.03), educational backgroud (χ2=17.33,P=0.000), employment status (χ2=7.97,P=0.005), personal monthly income (χ2=22.82, P=0.000), having any kinds of health insurance (χ2=16.08,P=0.000), and the health examination fees paid by company (χ2=44.78,P=0.000). Conditional logistic regress analysis showed that the related fators which affecting the peoples participating rates of taking health examination are gender (P=0.003, OR=1.782), residence registration (P=0.000, OR=2.208), personal monthly income (P=0.009, OR=1.307), taking any kinds of insurance (P=0.004,OR=2.913)and the company organizing and paying for the healthy examination or not (P=0.000,OR=1.923). Conclusion The participation rates of taking health examination were affected by the factors such as male, younger than 45 years old, divorce, temporary residents, the jobless, low educational diploma and income, not having any insurance, taking the health examinaiton at their own expense and so on.

Objective:To investigate the clinicopathological features and pathological diagnosis methods of calcifying fibrous tumor (CFT) of the stomach.Methods:The clinicopathological data of 9 patients with gastric CFT in the Second Hospital of Hebei Medical University from August 2015 to May 2020 were retrospectively analyzed, immunohistochemistry was used to detect the immunophenotypic characteristics of gastric CFT, and the relevant literature was reviewed.Results:Among 9 patients with gastric CFT, 1 case was male and 8 cases were female, with a median age of 53 years old (18-63 years old). There were 7 cases occurred in the body of the stomach, while 2 cases in the fundus. All cases were single solid nodule with the cut surface gray-white or gray-red in colour and hard and tough in texture. Maximum diameter of tumor ranged from 0.6 cm to 1.5 cm. Observation under the microscope showed the spindle-shaped tumor cells were sparsely distributed in a large amount of collagenized stroma with scattered lymphocytes and plasma cells infiltration. Calcification or gravel formation was detected in all cases. The tumor cells in 9 cases expressed Vimentin, 3 cases expressed CD34, none of them expressed PDGFRA, SMA, SMMS-1, Desmin, ALK, DOG-1, CD117, S-100, β-catenin, CKpan and calponin; Ki-67 positive index was 1%-3%.Conclusions:Gastric CFT is more common in middle-aged and elderly people, which is characterized by gastric body with smaller volume. The diagnosis of gastric CFT mainly depends on pathological morphology and immunohistochemical examination. It needs to be differentiated from a variety of spindle cell tumors more commonly found in the stomach.

Objective:To investigate the current status of hospitalized neonatal death of different gestational ages in Shaanxi Province.Methods:All neonatal deaths in six hospitals in Shaanxi Province from 2016 to 2020 were retrospectively analyzed, and the differences in perinatal complications, the causes of death, and the age at death were compared using Chi-square (or Fisher's exact ) test. Results:(1) Totally, 220 488 neonates were delivered in the obstetric department of the six hospitals during the study period; 71 782 out of them were admitted to the neonatal department. While 424 neonatal death was reported, giving the total hospitalized neonates mortality rate of 5.5‰ (394/71 782), which included 152 deaths of transferred patients ( n=9 103, 16.7‰), 226 premature (53.3%), 196 term (46.2%), and two post-term infants (0.5%). (2) Among mothers of dead neonates, 73.6% were found to have at least one perinatal complication. The most common one was fetal distress (146 cases, 34.4%), followed by gestational diabetes mellitus (113 cases, 26.7%), amniotic fluid abnormalities ( n=73, 17.2%), maternal infectious diseases ( n=71, 16.8%), and hypertensive disorders in pregnancy (HDP) ( n=52, 12.3%). The lower the gestational age, the higher the proportion of multiple pregnancies and assisted reproduction technology applied (Fisher exact test, P<0.05). On the contrary, the higher the gestational age, the higher the cesarean section rate ( χ 2=26.69, P<0.001). HDP was more likely to occur in the gestational age of 28-31 +6 and 32-34 +6 weeks ( χ 2=37.16, P<0.001), and amniotic fluid abnormalities were more likely to occur in those over 37 weeks ( χ 2=27.47, P<0.001). (3) The five leading causes of neonatal death were neonatal respiratory distress syndrome (NRDS, n=100, 23.6%), neonatal asphyxia ( n=88, 20.8%), maternal infectious diseases ( n=80, 18.9%), and birth defects ( n=54, 12.7%), and pulmonary hemorrhage ( n=22, 5.2%). The first three causes of death in term and post-term infants were neonatal asphyxia ( n=65, 32.8%), birth defects ( n=42, 21.2%), and infectious diseases ( n=26, 13.1%). NRDS ( n=83, 36.7%), infectious diseases ( n=54, 23.9%), and neonatal asphyxia ( n=23, 10.2%) were the three leading causes of death of premature babies. (4) Out of the 326 (76.9%) neonatal deaths within seven days after birth, 162 (38.2%) died within 24 h after birth and 164 cases (38.7%) between one to seven days after birth. Conclusions:Most neonatal deaths occurred among preterm ones and within seven days after birth, whose mothers suffered perinatal complications. The causes of neonatal death vary among different gestational age groups.

Objective:To investigate the diagnostic value of thyroid imaging report and data system (TIRADS) combined with BRAF V600E mutation detection in differentiating uncertain thyroid nodules by using fine needle aspiration cytology (FNAC), and to analyze the role of TIRADS classification in screening the nodules needed to be routinely detected for BRAF V600E mutation.Methods:The clinicopathological data of 337 thyroid nodules patients diagnosed with TIRADS classification, FNAC Bethesda classification, BRAF V600E mutation detection and postoperative histopathology from the Second Hospital of Hebei Medical University between January 2018 and August 2021 were retrospectively analyzed. The role of TIRADS classification, FNAC Bethesda classification and BRAF V600E mutation detection alone and the combined detection in the differentiation of benign and malignant thyroid nodules was also analyzed.Results:The postoperative histopathological result was regarded as the gold standard. The sensitivity of TIRADS classification, FNAC Bethesda classification and BRAF V600E mutation for thyroid cancer diagnosis was 76.0%, 88.1% and 80.4% respectively, and the corresponding specificity was 84.0%, 96.0% and 100.0%, respectively. Histologically, 37 (62.7%) of 59 nodules with FNAC uncertainty were malignant nodules after the surgery. The sensitivity and accuracy of BRAF V600E mutation detection in the diagnosis of FNAC uncertain nodules were 51.4% and 69.5%, respectively, while the sensitivity and accuracy of BRAF V600E mutation detection combined with TIRADS classification were 86.5% and 84.7%, respectively. The sensitivity and accuracy of BRAF V600E mutation detection combined with TIRADS classification were both improved ( P values were 0.002 and 0.049, respectively). The positive rate of BRAF V600E mutation in thyroid nodules increased step by step with the rise of risk degree in TIRADS classification, and the type 3 cases were lower than those in type 4a cases [14.3% (1/7) vs. 68.6% (24/35), P = 0.012], and there were no statistically significant differences among the adjacent groups above 4a (all P > 0.05). Conclusions:TIRADS combined with BRAF V600E mutation detection can improve the sensitivity and accuracy in the diagnosis of FNAC uncertain thyroid nodules. The BRAF V600E mutation rate of TIRADS 4a and above nodules is high, so routine detection is recommended.
