Objective:To explore the relationship between social support and negative emotion in parents of children with congenital heart disease before the operation.
Methods:Social support rating scale (SSRS), self-rating anxiety scale (SAS), and Center for epidemiological survey-depression scale (CES-D) were used to assess the association between social support and anxiety and depression in 226 parents.
Results:The mean SSRS score was signiifcantly lower than the normal. There was signiifcant difference in social support of parents in monthly family earning and knowledge about surgery. Parents with monthly family income≤1000 yuan had lower scores than the other groups. Parents who knew nothing about the surgery approach had lower scores. Social support was significantly correlated to negative emotion (anxiety and depression). Social support could predict anxiety and depression.
Conclusion:Social support is widely and significantly correlated to negative emotion in parents of children with congenital heart disease before the surgery.

Objective To explore any effect of proprioceptive neuromuscular facilitation (PNF) on the proprioception and balance of patients with knee osteoarthritis (KOA).Methods Forty patients with KOA were randomly divided into an experimental group (EG) and a control group (CG),each of 20.The PNF techniques of isotonic combined contraction,and rhythmic stable and dynamic reversal were applied in the EG,while the CG received quadriceps muscle strength training.Knee proprioception was evaluated using knee angle reconstruction experiments,and balance ability was measured using the one leg standing test (OLS) and the five times sit to stand test (FTSST).Results The errors in active and passive knee angle reconstruction at 30°,60° and 110° all improved significantly in the EG,but not in the CG.After the treatment,the OLS and FTSST results improved significantly in the EG,but only the OLS results improved significantly in the CG,not the FTSST times.Even so,the average OLS time in the EG was significantly longer than that of the CG after the training.Conclusion Proprioceptive neuromuscular facilitation can improve the proprioception and balance of persons with knee osteoarthritis.

AIM:To explore the preventive effect of resveratrol on spatial memory loss of the mice induced by intralateroventricular injection of calyculin A (CA).METHODS:Kunming mice of 2 months (n=44) were divided into saline control group, CA group, low-dose resveratrol group and high-dose resveratrol group.The mice in control group and CA group were intraperitoneally injected with equal volume of saline for 21 d, while the mice in low-dose resveratrol group and high-dose resveratrol group were intraperitoneally injected with resveratrol at 5 mg/kg and 10 mg/kg, respectively.At 22 d, CA (4 μL) was injected into the lateral ventricles in CA group, low-dose resveratrol group and high-dose resveratrol group.Morris water maze test was applied to examine the changes of learning and memory abilities of the mice at 27 d.The Golgi staining was used to observe the morphological changes of dendrites and dendritic spines.The hippocampal tissues were homogenated to detect SOD activity.RESULTS:Low-dose resveratrol significantly decreased the escape latency delay induced by CA.Low-dose resveratrol attenuated the decreases in the number of dendrites and the density of dendritic spines of neurons in hippocampal CA1 region induced by CA.High-dose resveratrol but not low-dose resveratrol attenuated the decreased SOD activity induced by CA.CONCLUSION:Resveratrol at low dose attenuates memory loss in the mice induced by CA though preventing dendrite injury.

Objective To observe the effect of acute normovolemic hemodilution(ANH)combined with enhanced recovery after surgery(ERAS)on immune function in patients undergoing hepatic lobectomy. Methods 80 patients were divided into two groups:ERAS group(group E),ANH combined with ERAS group(group AE). bleeding volume,blood transfusion,infused fluid volume,urine output during operation and clinical index after surgery were recorded. Exhaust and defecation time ,fluid intake time and hospitalization duration were also record-ed. Blood samples were obtained from the patients at 30 min before anesthesia induction(T1),immediately(T2), 24 h(T3),3 d(T4)and 7 d(T5)after the end of operation for determination of the expression of CD3+,CD4+, CD8+ on T cells and natural killer cell. Results In group E ,CD3+,CD4+ T-lymphocytes and NK cells at T2-3 decreased as compared with T0. Compared with group E ,no allogeneic blood transfusion cases were found and clinical index duration was shorter in group AE. CD3+,CD4+T-lymphocytes and NK cells at T2-3 increased in group AE as compared with those in Group E. The difference is significant (P < 0.05). Conclusion ANH combined with ERAS can decrease allogenic blood transfusion and increase post-operation immunologic function ,shorten the postoperative hospitalization time.

Objective To investigate the effect of fatty acid binding protein 4(FABP4)DNA methylation on abnormal lipid metabolism in placental trophoblastic dyslipidemia. Methods Human placental trophoblast cell line(HTR-8)was treated with L-NAME of 100 μmol/L for 48 h. The lipid content in placental trophoblasts was detected by chemical enzyme-colorimetry. The FABP4 DNA methylation level in placenta trophoblasts was detected by nested-touch down methylation specific PCR (NT-MSP). the mRNA and protein expression of DNMT1 and FABP4 were detected by qRT-PCR and Western Blot,respectively,in trophoblast cells. Results The lipid content in trophoblasts significantly increased as compared with the control(P < 0.05). Expression of FABP4 mRNA and protein increased(P < 0.05),while FABP4 methylation level and expression of DNMT1 significantly decreased (P<0.05)after treatment with L-NAME. Conclusions FABP4 DNA methylation is involved in the regulation of lipid metabolism in placental trophoblastic cells of hypertensive disorder complicating pregnancy.

Objective:To analyze the incidence of human papillomavirus (HPV) infection in 1 902 patients and to evaluate the efficacy of drug treatment in 266 patients, aiming to provide reference for the treatment of HPV infection.Methods:The subtypes of HPV isolated from 1 902 patients aged 15-86 years visiting the venereology outpatient clinic of Tianjin Medical University General Hospital from October 2019 to May 2021 were identified by polymerase chain reaction-reverse dot blot hybridization. Drug treatment efficacy in 266 patients of them was retrospectively analyzed.Results:The overall incidence of HPV infection in the 1 902 patients was as high as 53.84% (1 024/1 902). It was 52.60% (689/1 310) in males and 56.59% (335/592) in females. There was no significant difference in the incidence between males and females ( P>0.05). The most common HPV genotype in males and females was HPV6 [15.27% (200/1 310) and 21.96% (130/592)], followed by HPV16 [10.61% (139/1 310) and 9.46% (56/592)], HPV11 [9.31% (122/1 310) and 8.61% (51/592)], HPV52 [6.79% (89/1 310) and 8.95% (53/592)] and HPV43 [5.64% (87/1 310) and 8.45% (50/592)]. The majority of HPV-positive patients were aged between 20 and 39 years. There were 476 cases (25.03%, 476/1 902) of single-type infection and 548 cases (28.81%, 548/1 902) of multiple infection. The incidence of multiple infection was higher than that of single-type infection ( P<0.05). The incidence of multiple infection in females was higher than that in males ( P<0.05). Among the 266 patients, 106 were treated with Paiteling, a traditional Chinese medicine (TCM) preparation, and 68 of them tested negative (64.15%) after treatment. Fifty-eight patients were treated with recombinant human interferon α2b and 22 of them (37.93%) tested negative after treatment. Twenty out of the 56 subjects treated with imiquimod tested negative after treatment. Eight out of the 46 patients without treatment also turned negative. Conclusions:The incidence of HPV infection in the 1 902 patients visiting the venereology outpatient clinic was very high, and most of them were young adults. Multiple infection was more common than single-type infection. Topical application of drugs such as Paiteling, recombinant human interferon α2b and imiquimod was effective in treating HPV infection.

OBJECTIVETo investigate the expression patterns of ZEB2 and C-myc in epithelial ovarian cancer (EOC) and the associations between their expressions and the pathological features of EOC.

METHODSThe expressions of ZEB2 and C-myc proteins were detected immunohistochemically in 191 cervical cancer tissues and 13 normal ovarian tissues. The relationship between ZEB2 and C-myc protein expressions and the clinicopathological features of EOC was evaluated.

RESULTSZEB2 positive expression ratea in EOC tissues and normal ovarian tissues were 49.2% (94/191) and 30.8% (4/13), respectively (P=0.007), and C-myc positive expression rates in the two tissues were 53.9% (103/191) and 15.4% (2/13), respectively (P=0.001). A high expression of ZEB2 was positively correlated with the pathological type of the tumor (P=0.003), FIGO stage (P=0.028), T stage (P=0.002), and N stage (P=0.04), and a high expression of C-myc was positively correlated with FIGO stage (P=0.035), histological grade (P=0.039), and T stage (P=0.002). C-myc and ZEB2 expressions were positively correlated in EOC (P<0.001), and their co-expression in EOC was significantly correlated with T stage (R=0.358, P<0.001) and FIGO stage (P=0.008).

CONCLUSIONZEB2 and C-myc can promote the progression, invasion and metastasis of EOC, and their combined detection may assist in early diagnosis of EOC.

Objective: To analyze the detection rate of sleep problems such as sleep delay and deficiency in preschool children in the middle and lower reaches of the Yangtze River in China,and to provide the reference for the standard of sleeping mode among preschool students. Methods: From October to November 2017, a questionnaire survey was conducted among 27 200 preschool children in 11 cities in Hubei, Anhui and Jiangsu provinces in the middle and lower reaches of the Yangtze River in China. Epidemiology of sleep delays, deficiencies and sleep patterns in preschool children was described. Results: The detection rate of sleep problems in preschool children in the middle and lower reaches of the Yangtze River was 15.3%. Taking the length of sleep and bedtime as the main analysis points, it was found that the average sleeping time point of each age group was 21:31, and the detection rate of bedtime delay was 86.5%. The average length of sleep was (10.60±1.12) hours. The detection rate of sleep deprivation in preschool children was 15.7%. Sleep delay was positively correlated with girls, age increase and parents’ higher educational level (P<0.05), and negatively correlated with living in the city, non-only child and bedroom without TV (P<0.01) .The detection rate of sleep deprivation was positively correlated with children of high age group (4yearold group：OR=1.32，95%CI=1.19-1.46；5-year-old group：OR=2.10，95%CI=1.91-2.32；6-year-old group：OR=2.47，95%CI=2.20-2.77)(P<0.01), and negatively correlated with no TV in bedroom (OR=0.91，95%CI=0.84-0.98) and no light in sleep (OR=0.87，95%CI=0.78-0.97)(P<0.05). Conclusion Preschool children sleep delay and sleep deprivation and other sleep problems are more prominent, affected by family environment and other factors.

OBJECTIVES: To explore the psychological status of medical staff in the epidemic period of coronavirus disease 2019 (COVID-19), and to analyze its influential factors. METHODS: A total of 373 medical staff from Xiangya Hospital and the Second Xiangya Hospital of Central South University were enrolled for this study. The General Sociological Data Questionnaire, Symptom Check-List 90 (SCL-90), and self-designed public opinion response questionnaire were used to assess general sociological data, mental health scores, and ability to respond to COVID-19 related public opinion information of medical staff. The mental health scores of medical staff with different general sociological data and public opinion information coping abilities were compared. Influential factors of mental health were analyzed. RESULTS: The average score of 10 factors in SCL-90 of 373 medical staff was less than 2 points. 14.21% medical staff had one or more factor scores more than two points, including 11.26% with terror symptoms, 7.77% with compulsive symptoms, and 5.63% with anxiety. The main sources of COVID-19 information for medical staff included WeChat, microblog, Jinri toutiao, TV and radio. 66.22% medical staff regularly verified information about COVID-19 through official websites or formal channels. A great deal of COVID-19 information in WeChat could make medical staff nervous (34.05%), anxious (30.29%), and insecure (29.22%). 68.63% medical staff sometimes were worried about getting infected because they knew information about COVID-19. Different departments of medical staff, getting cough or having a fever recently, and the degree of fear of infection had an impact on the SCL-90 score of medical staff, the differences were all statistically significant (all <0.05). Stepwise regression analysis showed that the impact of COVID-19 information on their life in WeChat, getting cough or having a fever recently, insomnia-early caused by COVID-19 information in WeChat, different departments, and the degree of fear of infection COVID-19 were the influential factors for the mental health of medical staff (all <0.05). CONCLUSIONS During the epidemic of COVID-19, medical staff suffered from psychological problems to various degrees. It is necessary to establish a psychological assistance platform and guide the direction of public opinion correctly to promote the mental health of medical staff.
