Objective:To explore the effects of phased goal directed fluid therapy (GDFT) during anesthesia surgery on tissue perfusion and cognitive function in patients undergoing radical lung cancer surgery.Methods:A total of 108 lung cancer patients were prospectively selected and randomly divided into a control group and a study group using a random number table method. The control group received classical restrictive liquid therapy, while the study group received staged GDFT. We compared the surgical time, intraoperative blood loss, colloid fluid dosage, crystalloid fluid dosage, total output, and urine volume between two groups of patients; Two groups of patients were compared in terms of oxygenation index (OI), respiratory index (RI), central venous oxygen saturation (ScvO 2), lactate (Lac), central venous arterial carbon dioxide partial pressure difference (Pcv-aCO 2), oxygen supply index (DO 2I), and oxygen uptake rate (O 2ERe) before anesthesia induction (T 0), before single lung ventilation (T 1), 1 hour of single lung ventilation (T 2), immediate resumption of dual lung ventilation (T 3), 30 minutes of dual lung ventilation (T 4), and after surgery (T 5); The Mini Mental State Examination (MMSE) was used to evaluate the cognitive function scores of two groups of patients 1 day before surgery and 1 and 3 days after surgery, while recording the incidence of cognitive dysfunction (POCD) and pulmonary complications (including pulmonary infection, acute lung injury, pulmonary embolism, pulmonary edema, atelectasis, etc.) within 3 days after surgery. Results:The amount of crystal fluid and urine output in the research group was significantly lower than that in the control group, while the amount of colloidal fluid was significantly higher than that in the control group (all P<0.05). The OI of the study group T 1-T 5 was significantly higher than that of the control group, while the RI of T 2-T 5 was significantly lower than that of the control group (all P<0.05). The ScvO 2 of the study group T 1 to T 5 was significantly higher than that of the control group, and the Lac was significantly lower than that of the control group (all P<0.05); The MMSE scores of both groups of patients were significantly lower than those before surgery on day 1 and 3 after surgery, and the MMSE scores of the study group were significantly higher than those of the control group on day 1 and 3 after surgery (all P<0.05). The incidence of POCD within 3 days after surgery in the study group was 16.67%(9/54), lower than 37.04%(20/54) in the control group (χ 2=5.704, P=0.017); The incidence of pulmonary complications in the study group was lower than that in the control group (5.56% vs 22.22%, χ 2=4.955, P=0.026). Conclusions:The application of staged GDFT during anesthesia in patients undergoing radical lung cancer surgery can further improve tissue perfusion, improve microcirculation and oxygen supply-demand balance of systemic organs and tissues, including the brain, alleviate perioperative brain function damage, and reduce the occurrence of postoperative POCD compared to conventional liquid therapy.

Objective:To investigate the clinicopathological characteristics of acidophil stem cell pituitary neuroendocrine tumors (PitNET)/adenoma.Methods:Five cases of acidophil stem cell PitNET/adenoma were diagnosed between May 2022 and July 2023 at the Second Hospital of Hebei Medical University, Shijiazhuang, China. The clinicopathological features of the tumor were analyzed by using histology, immunohistochemistry, and electron microscopy. The relevant literature was reviewed.Results:There were 1 male and 4 females, aged from 23 to 69 years. Patient 3 was 55 years old at the time of diagnosis and first surgery, and relapsed 5 years later. The patients′ median age was 32 years. Patients 1 and 5 showed elevated blood prolactin, with various degrees of hormonal symptoms except Patient 3, who showed only tumor compression symptoms. Imaging studies showed that all cases involved the sellar floor. The tumors of Patients 1, 2 and 5 were closely related to the cavernous sinus segment of the internal carotid artery. The tumors exhibited a diffuse growth pattern with chromophobic to slightly acidophilic cytoplasm. A few of tumor cells showed chromophobic cytoplasm. The nucleoli were conspicuous. Intranuclear inclusion bodies and variably-sized clear vacuoles were observed occasionally. Under electron microscope, marked mitochondrial abnormalities were observed, including increased mitochondria number, expanded hypertrophy, and absence of mitochondrial ridge fracture. Some mitochondrial matrices were dense, while some were vacuolated.Conclusions:Acidophil stem cell PitNET/adenoma is a rare type of pituitary adenomas/PitNETs. It often has a more clinically aggressive manner with immature cells, diffuse expression of PIT1, prolactin, and varying degrees of growth hormone expression. Because of the obvious diversity of their clinical hormone status and hormone immune expression, the diagnosis of this type tumor is still a challenge.

ObjectiveTo investigate the value of MELD 3.0， MELD， and MELD-Na scores in assessing the 90-day prognosis of patients with acute-on-chronic liver failure （ACLF） through a comparative study. MethodsA retrospective analysis was performed for the clinical data of 605 patients with ACLF who were treated in Tianjin Third Central Hospital， The Fifth Medical Center of Chinese PLA General Hospital， and Beijing YouAn Hospital from November 2012 to June 2019， and according to the 90-day follow-up results after admission， they were divided into survival group with 392 patients and death group with 213 patients. The receiver operating characteristic （ROC） curve， the area under the ROC curve （AUC）， net reclassification improvement （NRI）， integrated discrimination improvement （IDI）， and decision curve analysis （DCA） curve were used to investigate the value of MELD 3.0， MELD， and MELD-Na scores at baseline， day 3， week 1， and week 2 in predicting the prognosis of the disease. ResultsAt day 3 and week 1， MELD 3.0 score had an AUC of 0.775 and 0.808， respectively， with a better AUC than MELD score （P<0.05）. At day 3， week 1， and week 2， MELD 3.0 score showed an NRI of 0.125， 0.100， and 0.081， respectively， compared with MELD in predicting the prognosis of ACLF patients， as well as an NRI of 0.093， 0.140， and 0.204， respectively， compared with MELD-Na score in predicting prognosis. At baseline， day 3， week 1， and week 2， MELD 3.0 showed an IDI of 0.011， 0.025， 0.017， and 0.013， respectively， compared with MELD in predicting the prognosis of ACLF patients. At day 3 and week 2， MELD 3.0 showed an IDI of 0.027 and 0.038， respectively， compared with MELD-Na in predicting the prognosis of ACLF patients. All the above NRIs and IDIs were >0， indicating a positive improvement （all P<0.05）. DCA curves showed that MELD 3.0 was superior to MELD at day 3 and was significantly superior to MELD-Na at week 2. There was no significant difference in the ability of the three scores in predicting the prognosis of ACLF patients with different types， and there was also no significant difference in the ability of the three scores in predicting the prognosis of ACLF patients with the etiology of HBV infection， alcohol， or HBV infection combined with alcohol， while MELD 3.0 was superior to MELD for ACLF patients with other etiologies （P<0.05）. ConclusionMELD 3.0 score is better than MELD and MELD-Na scores in predicting the 90-day survival of patients with ACLF， but with limited superiority.

Objective:To observe the influence of shared medical appointments on health-related quality of life and quality of sleep in patients after liver transplantation.Methods:By randomized controlled study, a total of 124 patients after liver transplantation were included from our hospital from January 2018 to January 2019, and according to the lottery method, all subjects were divided into the routine management group ( n=64) who received routine outpatient intervention and the shared medical management group ( n=60) who received shared medical appointments management. The health-related quality of life and quality of sleep were investigated and compared by post-liver transplant quality of life questionnaire (pLTQ) and Pittsburgh sleep quality index (PSQI) before intervention (the day of discharge) and after intervention (the end of the last shared outpatient service). Results:After intervention, the dimension scores of worry, economics, body function, emotional function, health service, complication and total score of pLTQ were improved in tow groups than before intervention [the routine management group: (41.90±7.61), (18.13±4.22), (22.22±5.10), (14.92±3.28), (20.39±4.87), (14.63±3.99), and (132.19±37.09) vs (32.25±5.55), (12.77±3.47), (17.58±4.72), (9.23±1.38), (15.17±4.81), (10.89±1.51) and (98.00±29.03) score, t=8.20, 7.85, 3.58, 12.79, 6.10, 7.01, 5.81, all P<0.001; shared medical management group: (46.12±7.92), (24.16±5.34), (25.55±5.42), (17.90±3.60), (24.81±5.12), (17.93±3.60) and (155.47±41.00) vs (32.57±5.69), (12.81±3.82), (17.00±4.70), (9.60±1.39), (15.39±4.84), (11.00±3.52) and (98.37±28.96) score, t=10.76, 13.39, 9.23, 16.66, 10.36, 10.66, 8.81, all P<0.001], and those in the shared medical management group were higher than those in routine management group ( t=3.03, 6.95, 3.53, 4.82, 4.93, 4.83, 3.32, all P<0.05). After intervention, the total score of PSQI scale were lower than before intervention in the routine management group [(10.48±2.14) vs (11.89±2.45) score, t=3.47, P=0.001], and the dimensions score of sleep quality, full-sleep time, sleep time, sleep efficiency, sleep disorders, daytime function, hypnotic and total score of PSQI were lower than before intervention in the shared medical management group [(1.41±0.32), (0.54±0.13), (1.17±0.26), (1.11±0.35), (1.21±0.27), (1.30±0.33), (1.08±0.21) and (8.05±1.75) vs (1.88±0.53), (0.86±0.37), (1.84±0.41), (2.05±0.56), (1.39±0.33), (1.47±0.43), (1.22±0.32) and (11.71±2.43) score, t=-5.88, -6.32, -10.69, -11.03, -3.27, -2.43, -3.65, -9.47, all P<0.05], and those in the shared medical management group were lower than those in routine management group ( t=-6.68, -6.39, -10.43, -10.97, -2.62, -2.12, -3.54, -6.90, all P<0.05). Conclusion:Shared medical appointments model can improve the health-related quality of life and quality of sleep in patients after liver transplantation, and improve the effectiveness of outpatient intervention.

Objective:To explore the effect of emergency rescue ability training of operating room nurses based on video tracking method, and provide reference for improving emergency ability of operating room nurses.Methods:This study was a quasi-experimental study. In March 2021, 85 nurses working in the Department of Anesthesiology and Surgery of the Provincial Hospital Affiliated to Shandong First Medical University were selected by cluster sampling method. We implemented a training program of rescue emergency ability based on video tracking and adopted the inspection list of rescue emergency ability assessment and doctors′ satisfaction questionnaire of operating room nurses to evaluate the scores of each item in the nurses' rescue emergency ability list and doctors' satisfaction of rescue cooperation of operating room nurses.Results:The scores of the dimensions of recognition of fatal arrhythmias, fatal arrhythmia, several situations that can directly call help, writing of emergency state nursing records and handover of medical records, use of defibrillator, correct use and maintenance of negative pressure attraction, use and management of rescue vehicle and situation disposal in the inspection list of rescue ability after training were 9.80 ± 1.61, 26.06 ± 2.20, 17.34 ± 1.29, 13.00 ± 1.57, 7.35 ± 0.74, 10.24 ± 1.14, 33.89 ± 2.73, which were higher than before training 9.24 ± 1.18, 24.92 ± 2.15, 15.69 ± 1.92, 12.21 ± 1.66, 6.55 ± 0.92, 8.94 ± 1.32, 32.94 ± 2.20. The differences were statistically significant ( t values were -6.83 to -2.51, all P<0.05); after the training, in the questionnaire of doctors' satisfaction with nurses, surgical materials and instruments preparation, first aid skill operating level, attention to surgical progress, active and correct delivery, orderly and busy, coordination and communication ability, professional knowledge, evaluation ability and foresight, ability to deal with emergencies, clear division of labor and good cooperation, and responsibility scores were 4.22 ± 0.58, 4.52 ± 0.54, 4.53 ± 0.47, 4.43 ± 0.58, 4.44 ± 0.44, 4.37 ± 0. 59, 4.45 ± 0.51, 4.51 ± 0.53, 4.51 ± 0.57, 4.17 ± 0.63, which were higher than the pre-training 4.05 ± 0.58, 4.38 ± 0.56, 4.26 ± 0.76, 4.04 ± 0.67, 4.25 ± 0.62, 4.19 ± 0.74, 4.25 ± 0.74, 4.34 ± 0.67, 4.21 ± 0.84 and 3.56 ± 0.58. All differences were statistically significant ( t values were -8.22 to -2.10, all P<0.05). Conclusions:The training method based on video tracking method improved the emergency rescue ability of operating room nurses and the doctor's satisfaction with rescue cooperation, and provided a reference for the training of operating room nurses.

Objective:To analyze the association between exposure to ambient PM 2.5 and its components [sulfate (SO 42-), nitrate (NO 3-), ammonium (NH 4+), organic matter (OM), and black carbon (BC)] and psychological distress among school children and adolescents aged 9 to 18 years in China. Methods:Based on data from the 2019 Chinese National Survey on Students' Constitution and Health, 130 808 children and adolescents aged 9 to 18 years were included. Scoring and determination of higher psychological distress were based on the Kessler Psychological Distress Scale (K10), and annual average exposure data for air pollution were matched by survey location and time. We used a restricted cubic spline approach based on logistic regression to fit the associations between PM 2.5, SO 42-, NO 3-, NH 4+, organic matter, black carbon concentrations, and psychological distress. Logistic regression models were used to analyse different age, gender, BMI and physical activity subgroups to estimate the association between exposure to high levels of pollution and high levels of psychological distress in different subgroups. Results:The proportion of children and adolescents with high levels of psychological distress in China was 30.4%, with girls being higher than boys at 31.6% and 29.1%, respectively ( P<0.05). A non-linear positive association existed between exposure to PM 2.5, SO 42-, NO 3- and organic matter concentrations and higher psychological distress. As PM 2.5, NO 3-, NH 4+, organic matter, and black carbon concentrations continued to rise, the increase in the risk of higher psychological distress slowed, while SO 42- showed little change in the OR of psychological distress at lower concentrations but continued to rise at higher concentrations. PM 2.5 and its components were statistically associated with psychological distress in the physically inactive group but not in the physically active group. The association between high levels of pollutants and high psychological distress was stronger among students aged 9 to 12 years compared with students aged 13 to 15 years and 16 to 18 years. Conclusions:The ambient pollutant PM 2.5 and its components are associated with psychological distress in children and adolescents aged 9 to 18 years in China. High pollutant exposure is a risk factor for high psychological distress among physically inactive children and adolescents, and there are age differences in the association between PM 2.5 and components and psychological distress.

Head and neck squamous cell carcinoma (HNSCC), as the most common type (>90%) of head and neck cancer, includes various epithelial malignancies that arise in the nasal cavity, oral cavity, pharynx, and larynx. In 2020, approximately 878 ‍ 000 new cases and 444 000 deaths linked to HNSCC occurred worldwide (Sung et al., 2021). Due to the associated frequent recurrence and metastasis, HNSCC patients have poor prognosis with a five-year survival rate of 40%-50% (Jou and Hess, 2017). Therefore, novel prognostic biomarkers need to be developed to identify high-risk HNSCC patients and improve their disease outcomes.

Objective: To evaluate the association of short-term fine particulate matters (PM2.5) exposure and blood pressure in children and adolescents. Methods: A total of 144 813 junior and senior middle school students who participated in the physical examination in the 2017-2018 academic year in a northern city of China, with complete record of demographic characteristics, blood pressure and no history of heart and other important organ diseases were selected as the study subjects. Data on PM2.5 and other pollutants and meteorological data were obtained from the nearest air quality and meteorological monitoring stations of each schools. A generalized linear mixed effect model was used to analyze the association between short-term exposure of PM2.5 and blood pressure. Results: The 6 day average concentration of PM2.5 (lag05) increased by 10 μg/m 3 was associated with an increase of 0.177(95%CI=0.148-0.207)mm Hg (1 mm Hg=0.133 kPa) in systolic blood pressure and 4.4%(OR=1.044, 95%CI=1.030-1.058) increase of the prevalence of high systolic blood pressure. And it was also associated with -0.021(95%CI=-0.040--0.002)mm Hg decrease in diastolic blood pressure, but had no significant correlation with the prevalence of high diastolic blood pressure. In general, a 10 μg/m 3 increase of PM2.5 was associated with 3.3% increase in the prevalence of high blood pressure (OR=1.03, 95%CI=1.02-1.05), and difference of boys and girls were found in different lagged days (P<0.05). Conclusion Short-term exposure of PM2.5 is associated with increased systolic blood pressure and prevalence of high blood pressure among children and adolescents. Attention should be paid to the prevention of short-term exposure of PM2.5 to protect the health of children and adolescents.

Objective:To evaluate the performance of high risk human papilloma virus (HR-HPV) E6/E7 mRNA in triaging women with atypical squamous cells of undetermined signification (ASCUS).Methods:The ASCUS cohort determined by liquid-based cytology test in the cervical cancer screening queue in Luoshan County, Xinyang City, Henan Province 2017 were selected. The population underwent colposcopy biopsy and pathological tests, combined with HPV16 or 18 (HPV16/18), HR-HPV DNA and HPV E6/E7 mRNA test. By using the pathological result as the gold standard, the sensitivity, specificity, positive predictor (PPV), negative prediction (NPV), referral rate and 95% confident interval ( CI) of HPV E6/E7 mRNA, HR-HPV DNA, HPV16/18 were calculated, respectively. Results:The average age of 312 ASCUS women was 52.6±7.3 years old. Among the 290 women diagnosed as normal by pathology, 64 (22.1%) were HPV E6/E7 mRNA positive, 86 (29.7%) were HR-HPV DNA positive, and 19 (6.6%) were HPV16/18 positive. All of the cervical intraepithelial neoplasia (CIN) cases determined by pathology were both HPV E6/E7 mRNA and HR-HPV DNA positive. The sensitivity, specificity, PPV, NPV and referral rate of HPV E6/E7 mRNA for predicting CIN2+ lesion in women with ASCUS were 100.0% (95% CI: 72.3, 100.0), 77.8% (95% CI: 72.8, 82.1), 13.0% (95% CI: 7.2, 22.3), 100.0% (95% CI: 98.4, 100.0) and 24.7%. Compared with HPV E6/E7 mRNA, the sensitivity of HR-HPV DNA was similar with HPV E6/E7 mRNA, but with a lower specificity [70.2% (95% CI: 64.8, 75.1), P<0.05], a higher referral rate (32.1%, P<0.05); while HPV 16/18 had a high specificity (93.4%, 95% CI: 90.0, 95.7) and a low sensitivity (30.0%, 95% CI: 10.8, 60.3). Based on the age stratification by age 45, the sensitivity of HPV E6/E7 mRNA in both age groups was 100.0%. The specificity of HPV E6/E7 mRNA in group of ≥45 years was a little higher than that in group of <45 years [79.0% (95% CI: 73.7, 83.5) versus 68.3% (95% CI: 53.0, 80.4)], but the difference was not statistically significant ( P>0.05). Conclusions:The ASCUS woman triaging effect of HPV E6/E7 mRNA detection is better than those of HR-HPV and HPV16/18 under certain conditions. The application of HPV E6/E7 mRNA detection to triage ASCUS population can avoid unnecessary colposcopy referral and reduce the missed diagnosis of cervical lesions.
