Objective:To study the early predictors of refractory septic shock (RSS) in neonates.Methods:From July 2020 to December 2021, clinical data of neonates with septic shock admitted to the Neonatal Department of our hospital were retrospectively reviewed. According to the maximum septic shock score (SSS) during clinical course, the neonates were assigned into RSS group and non-RSS group. Perinatal data, laboratory results and hemodynamic parameters at diagnosis were compared between the two groups. Multiple logistic regression analysis was used to identify independent risk factors of RSS and septic shock-related death. Receiver operating characteristic (ROC) curve was constructed to evaluate the early predictors of poor prognosis.Results:A total of 130 neonates were enrolled, including 54 in RSS group and 76 in non-RSS group. Compared with the non-RSS group, the RSS group had significantly lower pH, base excess (BE), stroke volume index (SVI), cardiac output (CO) and cardiac index (CI).Meanwhile, the RSS group had significantly higher mean arterial pressure (MAP) to CI ratio (MAP/CI) and SSS [including bedside SSS (bSSS), computed SSS (cSSS) and modified version of cSSS (mcSSS)] (all P<0.05). Multiple logistic regression analysis showed that increased MAP/CI was an independent predictor of RSS. The cut-off value of MAP/CI was 11.6 [sensitivity 62%, specificity 87%, positive predictive value (PPV) 79% and negative predictive value (NPV) 77%], with an area under the curve (AUC) of 0.734. Increased mcSSS was an independent predictor of septic shock-related death. The cut-off value of mcSSS was 5.8 (sensitivity 83%, specificity 72%, PPV 21% and NPV 97%), with an AUC of 0.845. Conclusions:Increased MAP/CI (≥11.6) and mcSSS (≥5.8) may be early predictors of RSS and septic shock-related death in neonates.

Objective To explore the application value of ultrasound-guided use of bupivacaine for subarachnoid block in hip replacement surgery for elderly femoral neck fractures.Methods A total of 108 elderly patients who underwent hip replacement surgery at Ganzhou Traditional Chinese Medicine Hospital from March 2020 to March 2022 were selected as the study subjects.They were divided into conventional anesthesia group and ultrasound guided anesthesia group by means of random number table,54 cases in each group.Patients in the conventional anesthesia group received routine general anesthesia;Patients in the ultrasound guided anesthesia group received unilateral lumbar anesthesia with bupivacaine under ultrasound-guided guidance.Compare the effectiveness of two anesthesia methods during surgery.Results Compared with the conventional anesthesia group,the anesthesia effect of the ultrasound guided anesthesia group was better(P<0.05);The surgery time,amount of bleeding during surgery,postoperative recovery time,and length of hospital stay in the ultrasound guided anesthesia group were all lower than those in the conventional anesthesia group(P<0.05).The ultrasound guided anesthesia group performed better in terms of hemodynamic stability,with a smaller range of changes,and significantly lower pain scores at different postoperative time points compared to the conventional anesthesia group(P<0.05).Conclusion In elderly patients undergoing hip replacement surgery,using ultrasound-guided bupivacaine for subarachnoid block can achieve ideal anesthesia and analgesic effects compared to traditional general anesthesia,shorten drug onset time,alleviate pain in elderly patients,maintain hemodynamic stability,and have significant clinical application effects.

Objective To explore the risk factors for vaginal stump recurrence after early cervical cancer surgery.Methods A total of 243 patients who underwent radical cervical cancer surgery in the First Affiliated Hospital of Henan University of Science and Technology from January 2018 to March 2020 were selected as the research subjects and divided into recurrence group(n=21)and non-recurrence group(n=22)based on whether vaginal stump recurrence occurred within 3 years after surgery.The clinical data of patients in the two groups,including age,pathological type,International Federation of Gynecology and Obstetrics(FIGO)staging of cervical cancer,degree of tissue differentiation,surgical approach,distance between surgical margin and tumor,muscle layer infiltration,presence or absence of lymph node involvement at diagnosis of cervical cancer,number of tumor budding,presence or absence of vascular cancer thrombus,vaginal resection length,and postoperative radiotherapy site were collected.One-way analysis of variance and binary logistic regression were used to analyze the risk factors for vaginal stump recurrence after early cervical cancer surgery.Results The recurrence rate of vaginal stumps within 3 years after early cervical cancer surgery was 8.64％(21/243).There were statistically significant differences in the pathological types,distance between surgical margin and tumor,muscle layer infiltration,number of tumor budding,vaginal resection length,and postoperative radiotherapy site of patients between the recurrence group and non-recurrence group(P＜0.05);there was no statistically significant difference in the age,FIGO stage,degree of tissue differentiation,surgical approach,presence or absence of lymph node involvement at diagnosis of cervical cancer,presence or absence of vascular cancer thrombus of patients between the two groups(P＞0.05).The binary logistic regression analysis showed that the distance between the surgical margin and the tumor≤3.5 mm,the number of tumor budding＞5,and the vaginal resection length≤2 cm were risk factors for vaginal stump recurrence after early cervical cancer surgery(P＜0.05),while postoperative pelvic radiotherapy combined with vaginal brachytherapy was a protective factor for vaginal stump recurrence after early cervical cancer surgery(P＜0.05).Conclusion The risk of vaginal stump recurrence after early cervical cancer surgery is high.The distance between the surgical margin and tumor≤3.5 mm,the number of tumor budding＞5,and the vaginal resection length≤2 cm are risk factors for vaginal stump recurrence after early cervical cancer surgery;pelvic radiotherapy combined with vaginal brachytherapy can reduce the risk of vaginal stump recurrence after early cervical cancer surgery.

Autophagy is a cellular self-degradation process essential for maintaining metabolic functions in cells and organisms.Dysfunc-tional autophagy has been linked to various diseases,including cancer.The m6A modification,a major RNA modification in eukaryotes,plays a crucial role in regulating autophagy in tumor cells by regulating the expression of autophagy-associated genes(ATGs)or interfering with autophagy-related signaling pathways.Aberrant m6A modification can lead to dysregulated autophagy and impact tumor progression.However,the specific role of m6A in regulating tumor autophagy remains to be explored.Therefore,in this review,we discuss the role of m6A modification in tumor cell autophagy and examine its relationship with tumor progression and drug resistance,aiming to provide a the-oretical foundation for developing new therapeutic strategies.

Objective:To evaluate the effectiveness of oral-nasal oxygen supply mouth guard in painless gastroscopy for snoring patients.Methods:The snoring patients who underwent painless gastroscopy at two Endoscopy Centers of Shanghai East Hospital, Tongji University in July 2022 were randomly divided into the observation group (using oral-nasal oxygen supply mouth guard) and the control group (using ordinary nasal oxygen tube and mouth guard). Parameters such as the wearing time and the removal time of the mouth guard, lowest pulse oxygen saturation (SpO 2), incidence of hypoxemia, and the satisfaction of medical staff were compared between the two groups. Results:The wearing time of mouth guard was 11.63±0.84 seconds and the removal time was 5.33±0.76 seconds in the observation group ( n=40), which were lower than those in the control group ( n=47) (14.91±1.21 seconds, t=-14.463, P<0.001; 10.38±0.80 seconds, t=-30.095, P<0.001). The wearing satisfaction score was 9.80±0.61, the lowest SpO 2 was (96.70±3.42)%, the removal satisfaction score was 9.75±0.67, and the anesthesiologists' satisfaction score was 9.20±1.42 in the observation group, which were higher than those in the control group [7.70±0.93, t=12.209, P<0.001; (94.06±3.72)%, t=3.417, P=0.001; 7.96±0.98, t=9.803, P<0.001; 8.13±1.35, t=3.615, P=0.001] with significant difference. There was no significant difference in the incidence of hypoxemia [10.00% (4/40) VS 14.89% (7/47), χ2=0.130, P=0.718] and endoscopic physician satisfaction score (9.30±0.97 VS 9.02±1.31, t=1.112, P=0.269) between the two groups. Conclusion:The oral-nasal oxygen supply mouth guard is easy to wear and remove, effectively reducing SpO 2 fluctuations during painless gastroscopy for snoring patients. It can enhance medical staff satisfaction with high clinical value.

The respondents included 1 075 men (49.49%) and 1 097 women (50.51%). There were 623 respondents that met the target of the mental health literacy (28.68%). Multivariable logistic regression analysis showed a higher possibility of achieving the target of mental health literacy levels among women than among men (OR=1.282, 95%CI: 1.047-1.570), among unmarried residents (OR=1.685, 95%CI: 1.018-2.788) than among married residents, among residents with educational levels of junior high school (OR=1.689, 95%CI: 1.168-2.441), high school/vocational high school/technical secondary school (OR=2.420, 95%CI: 1.601-3.658) and college or above (OR=3.543, 95%CI: 2.252-5.574) than among residents with an educational level of primary and below, among students (OR=2.572, 95%CI: 1.013-6.527), medical personnel (OR=3.330, 95%CI: 2.029-5.467), teachers (OR=2.909, 95%CI: 1.202-7.040), freelance/self-employed staff (OR=1.519, 95%CI: 1.100-2.098) and other professional technical personnel (OR=1.529, 95%CI: 1.012-2.310) than among workers. Conclusions The proportion of mental health literacy levels meeting the target is high among residents in Jiaxing City, and gender, educational level, occupation and marital status are factors affecting mental health literacy levels.

Objective:To explore the effect of quality improvement of hemodynamic monitoring on fluid overload (FO) and outcome in newborns with septic shock.Methods:Non-invasive cardiac output monitoring and functional cardiac ultrasound quality improvement program was started during January 2020 in our hospital. Neonates with septic shock admitted before and after the program were retrospectively analyzed. From January 2018 to December 2019 was pre-improvement period when fluid resuscitation was routinely performed and vasoactive drugs was selected empirically. From January 2020 to December 2021 was post-improvement period when fluid resuscitation and/or use and adjustment of vasoactive drugs were guided by hemodynamic parameters. The 24 h, 48 h, 72 h FO, duration of invasive respiratory support, vasoactive-inotropic score, septic shock score, incidences of complications and all-cause mortality were compared between the two groups.Results:A total of 284 eligible cases were enrolled, including 136 cases in pre-improvement group and 148 cases in post-improvement group. Post-improvement group had significantly lower gestational age (GA), birth weight (BW) and body weight at disease onset than pre-improvement group ( P<0.05). Incidences of 48 h and 72 h FO, fluid resuscitation volume within 72 h, pulmonary hemorrhage and periventricular leukomalacia (PVL) were significantly lower in the post-improvement group ( P<0.05). No significant differences existed in 24 h FO, other complications and all-cause mortality between the two groups ( P>0.05). No significant differences existed in GA and BW for neonates with pulmonary hemorrhage and PVL between the two groups ( P>0.05). Conclusions:Quality improvement of hemodynamic monitoring can effectively improve FO and reduce the incidences of pulmonary hemorrhage and PVL.

Objective:To study the predictive value of vasoactive-inotropic score (VIS), fluid overload (FO) and lactate level for the outcome of preterm infants with refractory septic shock.Methods:Preterm infants diagnosed with refractory septic shock and required hydrocortisone treatment in our Department from January 2016 to December 2021 were analyzed retrospectively. Preterm infants were assigned into three gestational age groups (<28 weeks, 28-31 weeks, 32-36 weeks). According to the outcome of the disease, the children were further divided into good prognosis group and poor prognosis group. The relationship between the maximum VIS, FO and the mean lactic acid before hydrocortisone and the outcome of refractory septic shock was analyzed by receiver operating characteristic (ROC) curve, the cut-off point of ROC curve was calculated to obtain the predictive efficacy of the three indicators for the outcome of refractory septic shock in preterm infants.Results:A total of 50 preterm infants with refractory septic shock and received hydrocortisone treatment were enrolled, including 20 in the good prognosis group and 30 in the poor prognosis group. There were no significant differences in the maximum VIS, FO and mean lactic acid before hydrocortisone treatment between the two groups of gestational age of <32 weeks ( P> 0.05). The maximum VIS, FO and mean lactic acid of gestational age of 32-36 weeks in the poor prognosis group were higher than those in the good prognosis group, VIS: 56.1±15.7 vs. 37.1±12.9, FO (%): 108.2 (78.6,137.7) vs. 55.5 (10.3, 100.7), and mean lactic acid (mmol/L): 8.3 (4.6, 12.0) vs. 4.8 (-0.8, 10.5), all P<0.05. The area under the ROC curve of the mean lactic acid was the largest, the cut-off value was 4.1 mmol/L, and the Youden index was 1.732. Conclusions:VIS, FO and lactate level are difficult to be used for determining the outcome of refractory septic shock in preterm infants of <32 weeks. While the mean lactic acid has the best predictive performance in preterm infants of 32-36 weeks.

Objective:To explore the mediating role of self-perceptions of aging between frailty and cognitive function in community-dwelling older adults.Methods:From February to July 2021, a total of 528 elderly people in Xinxiang community were investigated with the frailty phenotype, the brief self-perceptions ageing questionnaire and the Mini-mental state examination(MMSE) scale.According to the MMSE total score and education level, the subjects were divided into cognitive impairment group (illiteracy≤17, primary school≤20, junior high school and above≤24, n=74) and cognitive normal group( n=454). SPSS 25.0 software was used for common method deviation test, descriptive statistics and correlation analysis, while AMOS 24.0 software was used to build structural equation model and Bootstrap method was used for intermediary effect test. Results:(1)The prevalence of cognitive impairment among the elderly in the community was 14.1%. The differences between the cognitively normal group and cognitively impaired group were statistically significant in terms of age, education, number of chronic diseases suffered and depression ( χ2=59.21, 6.53, 9.84, 25.47, all P<0.05). The differences were statistically significant in terms of frailty( χ2=75.65, P<0.001) and self-perceptions of aging ( t=77.67, P<0.001). (2)Self-perceptions of aging in the cognitively impaired group (47.39±8.66) was higher than that in the cognitively normal group (38.22±8.24) ( t=77.67, P<0.001) .Frailty score in cognitively impaired group (2.00 (1.00, 3.00)) was higher than that in the cognitively normal group (0.00 (0.00, 1.00))( Z=-8.63, P<0.001) . (3)Frailty was negatively correlated with cognitive function ( r=-0.492, P<0.01), and positively correlated with self-perceptions of aging ( r=0.540, P<0.01). Self-perceptions of aging was negatively correlated with cognitive function ( r=-0.541, P<0.01) . After controlling the influencing factors such as age, education level, chronic diseases and depression, the correlation was still significant (all P<0.01) . (4) Self-perceptions of aging played a partially mediating role in the relationship between frailty and cognitive function, the mediating effect accounted for 58.5% of the total effect. Conclusion:Frailty and self-perceptions of aging have a significant impact on the cognitive function of the elderly in the community, and self-perceptions of aging plays a partial intermediary role between the frailty and cognitive function of the elderly in the community.

This article reports a case of adrenal tumor in a reproductive-aged woman with hyperandrogenism misdiagnosed as polycystic ovary syndrome. The patient presented with menstrual disorder, elevated testosterone levels, and polycystic ovaries, initially diagnosed as polycystic ovary syndrome. Menstrual regularity was achieved after intermittent use of ethinylestradiol/cyproterone acetate and progesterone. Five years later, during a physical examination, a mass was discovered in the right adrenal gland, accompanied by elevated testosterone levels, polycystic ovaries, obesity, and insulin resistance. Laparoscopic resection of the right adrenal tumor was performed, and the pathological diagnosis was adrenal cortical oncocytoma. Postoperatively, menstrual regularity was restored, and testosterone levels normalized. This case highlights the importance of considering adrenal tumors secreting androgens in patients clinically diagnosed with polycystic ovary syndrome, and emphasizes the need for regular adrenal imaging follow-up.
