Objective To construct,implement and evaluate the effectiveness of the virtual simulation technology-based prenatal health education course.Methods The curriculum included 4 parts:"warm delivery room and easy delivery","medicated analgesic delivery","non-medicated analgesic delivery"and"early maternal and infant health care".From May to September 2022,100 primiparas in an obstetrics and gynecology hospital in Zhejiang Province were investigated by convenient sampling method.Random number table method was used to divide the participants into an experimental group and a control group,with 50 participants per group.The control group received conventional health education,while the experimental group received an augmented virtual reality technology-based prenatal health education course during the late stages of pregnancy on this basis.We conducted a post-intervention comparative analysis of antenatal anxiety levels,fear of childbirth,and birth outcomes between the 2 groups.Furthermore,a post-intervention satisfaction survey was administered to the experimental group.Results After intervention,the antenatal anxiety of the experimental group was lower than that of the control group(x2=4.943,P=0.026),and the decrease in fear of childbirth scores was higher than that of the control group(t=3.200,P=0.002).The experimental group was highly satisfied with all of the 4 dimensions of the course,and the overall evaluation was(31.8±3.23)points.However,there were no significant differences in vaginal delivery rate,postpartum bleeding volume,postpartum hemorrhage incidence,perineal injury degree and duration of each labor stage between the 2 groups(P＞0.05).Conclusion The virtual reality technology-based prenatal health education course was effective in improving the antenatal anxiety and fear of childbirth of primipara,and the use satisfaction is high.

Senescence of activated hepatic stellate cells (aHSCs) is a stable growth arrest that is implicated in liver fibrosis regression. Senescent cells often accompanied by a multi-faceted senescence-associated secretory phenotype (SASP). But little is known about how alanine-serine-cysteine transporter type-2 (ASCT2), a high affinity glutamine transporter, affects HSC senescence and SASP during liver fibrosis. Here, we identified ASCT2 is mainly elevated in aHSCs and positively correlated with liver fibrosis in human and mouse fibrotic livers. We first discovered ASCT2 inhibition induced HSCs to senescence in vitro and in vivo. The proinflammatory SASP were restricted by ASCT2 inhibition at senescence initiation to prevent paracrine migration. Mechanically, ASCT2 was a direct target of glutaminolysis-dependent proinflammatory SASP, interfering IL-1α/NF-κB feedback loop via interacting with precursor IL-1α at Lys82. From a translational perspective, atractylenolide III is identified as ASCT2 inhibitor through directly bound to Asn230 of ASCT2. The presence of -OH group in atractylenolide III is suggested to be favorable for the inhibition of ASCT2. Importantly, atractylenolide III could be utilized to treat liver fibrosis mice. Taken together, ASCT2 controlled HSC senescence while modifying the proinflammatory SASP. Targeting ASCT2 by atractylenolide III could be a therapeutic candidate for liver fibrosis.

Objective To explore the application value of ultrasound-guided stellate ganglion block in patients with aneurysmal cerebral hemorrhage.Methods Eighty patients with subarachnoid hemorrhage caused by aneurysm from November 2017 to March 2019 in Hangzhou Hospital of Zhejiang Medical Health Group were selected.The patients were divided into observation group and control group by random digits table method with 40 cases in each group.All patients were treated with craniotomy hematoma removal.At the conclusion of the surgical procedure,the control group was treated with nimodipine,while the observation group was treated with ultrasound-guided right stellate ganglion block on the basis of nimodipine.The blood flow velocity of middle cerebral artery before operation and 6,24 h after operation by transcranial Doppler sonography were detected to reflect cerebral vasospasm status;the blood samples from the radial artery and internal jugular bulb 24 h after operation were used to detect and count cerebral oxygen metabolism indexes,including the blood oxygen saturation of internal jugular bulb,arteriovenous oxygen content difference and cerebral oxygen uptake rate;the IgG,IgA and IgM 24 h after operation were detected.The patients were followed up at 1 week after operation,and the complication was observed.Results There was no statistical difference in the blood flow velocity of middle cerebral artery before operation between 2 groups (P＞0.05);the blood flow velocity of middle cerebral artery 6 and 24 h after operation in observation group was significantly lower than that in control group:(100.8± 8.2) cm/s vs.(123.5 ± 9.9) cm/s and (89.7 ± 5.3) cm/s vs.(118.9 ± 7.1) cm/s,and there was statistical difference (P＜0.01).The blood oxygen saturation of internal jugular bulb,cerebral oxygen uptake rate,IgG,IgA and IgM 24 h after operation in observation group were significantly higher than those in control group:0.704 ± 0.035 vs.0.598 ± 0.058,(57.5 ± 6.5)％ vs.(49.7 ± 3.6)％,(12.5 ± 0.3) mg/L vs.(5.0 ± 0.1) mg/L,(5.5 ± 0.3) mg/L vs.(2.1 ± 0.1) mg/L and (4.3 ± 0.3) mg/L vs.(1.9 ± 0.2) rg/L,the arteriovenous oxygen content difference and incidence of complication were significantly lower than those in control group:(40.8 ± 3.2) ml/L vs.(58.3 ± 8.6) ml/L and 5.0％ (2/40) vs.25.0％ (10/40),and there were statistical differences (P＜0.01 or ＜0.05).Conclusions For patients with aneurysmal intracerebral hemorrhage,ultrasound-guided stellate ganglion block therapy can effectively improve cerebral blood flow,ensure cerebral oxygen supply,improve humoral immunity,reduce the incidence of postoperative complication,and achieve the purpose of improving clinical therapeutic effect.

Objective:To screen and identify autoantibody biomarker to diagnose patients with nasopharyngeal carcinoma (NPC).Methods:Candidate autoantibodies against tumor-associated antigens were identified from NPC CNE2 cells using serological proteome analysis. Levels of candidate autoantibody biomarkers were measured by enzyme-linked immunosorbent assay (ELISA) in 50 patients with NPC and 80 normal controls recruited from the Cancer Hospital of Shantou University Medical College between July 2014 and January 2015. Receiver operating characteristic curve (ROC) was employed to evaluate diagnostic efficacy.Results:Serological proteome analysis showed that sera from patients with NPC yielded a positive spot, of which was identified as enolase 1 (ENO1). ELISA results showed that the level of serum autoantibody against ENO1 in patients with NPC was significantly higher than that in normal controls [0.165 (0.088, 0.378) vs. 0.100 (0.054, 0.117), Z=4.077, P<0.001]. With the optimum diagnostic cutoff of 0.164, ROC curve showed the diagnostic sensitivity and specificity of autoantibodies against ENO1 were 52.0% and 90.0%, respectively. Measurement of autoantibody against ENO1 demonstrated a positive rate of 75.0% for early stage NPC. Conclusion:Autoantibody against ENO1 may be a potential diagnostic biomarker for NPC.

Objective:To investigate the utilization of peripheral intravenous catheter (PIVC) in hospitalized children in Class Ⅲ specialized children's hospitals, aiming to discover existing issues of PIVC in order to provide reference for clinical nurses and nurse administer to improve the quality on intravenous therapy and to avoid potential risk.Methods:This study uses the field survey method. From July 23rd to 31st, 2018, 25 Class Ⅲ children's specialized hospitals were first sampled in 23 provinces, municipalities, and autonomous regions of the country by the convenient sampling method. The cluster sampling method was then used to select all the pediatric patients with PIVCs admitted to the hospital on the date of investigation. A self-designed 'Cross-sectional Questionnaire for Pediatric Patients with PIVC' was used for survey, and images and data were analyzed. SPSS 17.0 software was used to statistically analyze the data.Results:In this study, 8 635 cases of PICVs were investigated, and the utilization rate of PICVs accounted for 86.9% (8 635/9 942) of all venipuncture tools. Among these cases, 4 665 (54.0%) cases' puncture sites were at the dorsal side of the hand, and 1 234 (14.3%) were at the head. Among the PIVCs, 45.8% (3 954/8 635) were safety PIVCs. And 54.6% (4 712/8 635) of the PIVCs were di (2-ethylhexyl) phthalate (DEHP) free products. The incidence rate of PICV related complications was 7.9% (682/8 635) . Univariate analysis and multivariate logistic regression analysis showed that the PIVC time, IV site, dressing fixation problems, catheter maintenance problems, and patient age were risk factors for PIVC related complications ( P<0.05) . Conclusions:PIVC is the widely used among pediatric patients. The IV site is mainly at the dorsal side of the hand, followed by head and wrist. The selection of material and type of PIVC still require further improvement to ensure the safety of pediatric intravenous therapy. Nursing measures should be taken during the use of PIVC to identify the risk factors at early stage and intervene effectively, which can reduce the occurrence of complications.

In this study, apoptotic mechanism of resveratrol against human prostatic carcinoma DU145 cells was investigated. MTT was used to measure cell growth and proliferation. Reactive oxygen species(ROS)kit was used to analyze ROS level. Cell apoptosis and cell cycle analysis were observed by flow cytometry. Protein expression levels of apoptosis and pathway associated were analyzed by Western blot. The result shows that DU145 cells treated with different resveratrol concentrations suffered apoptosis, cycle arrest in G0/G1 phase, ROS increase in the cell and a decrease in mitochondrial membrane potential(MMP, ΔΨm), in a concentration-dependent manner. Resveratrol inhibited the expression of Bcl-2 protein via up-regulating Bax protein, thus increasing the ratio of Bax/Bcl-2, activating Caspase reaction and led apoptosis ultimately. Further investigation confirmed that resveratrol increased ROS level, decreased MMP and consequently induced apoptosis via michondrial-mediated pathway in DU145 cells. Therefore resveratrol may induce apoptosis via ROS-michondrial pathway in DU145 cells.

Objective To investigate the positive influence of telephone follow-up on primiparas′exclusive breastfeeding during puerperal period. Methods By using convenience sampling method, 90 primiparas were selected who had given birth in the integration ward of our hospital from October to December 2015 as the control group, and 60 primiparas were selected who had given birth in the integration ward of our hospital from December 2015 to January 2016 as the experimental group. For the experimental group, every 2 weeks, a telephone follow-up was executed according to primiparas′parturition time after leaving hospital. For the control group, telephone follow-up was not executed. The influence of periodic telephone follow-up on primiparas′ exclusive breastfeeding was observed. Results The exclusive breastfeeding rate of primiparas in the experimental group was increased as the telephone follow-up was executed. It was up to 91.7%(55/60) 6 weeks since parturition. The exclusive breastfeeding rate of primiparas in the control group was 71.1% (64/90). The difference was significant (χ2=9.28, P<0.01). Conclusions Periodic telephone follow- up according to necessity provides breastfeeding publicity and guidance after parturition, maintaining the continuous education and caring for the primiparas after leaving hospital which efficiently increased the pure breastfeeding rate of primiparas during puerperal period.
