Objective To investigate the predictive value of continuous dynamic monitoring of intrapulmonary shunt (Qs/Qt) in patients with acute respiratory distress syndrome (ARDS).Methods A prospective observational study was conducted.The adult patients with ARDS undergoing mechanical ventilation admitted to intensive care unit (ICU) of Tianjin Third Central Hospital from June 2014 to December 2015 were enrolled.Baseline characteristics,demographic data and relevant physiologic data were recorded.All patients were divided into survivors and non-survivors according to the outcome of patients within 28 days.Artery and mixed venous blood was collected immediately after admission for blood gas analysis,and daily Qs/Qt within 7 days was continuously monitored in ARDS patients.The receiver operating characteristic curve (ROC) was used to evaluate the prognosis accuracy of Qs/Qt.Results In 46 enrolled ARDS patients,20 died,and 26 survived.During the first 7 days of ARDS,the mean Qs/Qt in survivors showed an increasing tendency [(23 ± 6)％,(27 ± 6)％,(28 ± 9)％,respectively,at 1-3 days] and a downtrend tendency from 4 days [(27 ± 5)％,(25 ± 4)％,(19 ± 4)％,(16 ± 2)％,respectively,at 4-7 days].However,a rising tendency of Qs/Qt in non-survivors was found at 1-7 days [(28 ± 7)％,(30 ± 3)％,(33 ± 6)％,(33 ± 11)％,(34 ± 5)％,(33 ± 6)％,(35 ± 6)％,respectively],and Qs/Qt from the 5th day in non-survivors was significantly higher than that in survivors (all P ＜ 0.05).The fluctuation of oxygenation index (PaO2/FiO2) within 1 week in both groups was small,and PaO2/FiO2 (mmHg,1 mmHg =0.133 kPa) at 1-7 days in survivors was 167.37±43.98,180.55±39.90,174.27±35.47,188.64±39.74,252.54±49.22,239.35±25.63,248.93±45.64,respectively,and it was 168.65±35.54,182.31 ± 32.36,159.80 ± 34.39,176.97 ± 31.75,200.69 ± 45.33,185.98 ± 36.47,and 175.43 ± 30.98 in non-survivors respectively.PaO2/FiO2 was significantly lower in non-survivors than survivors from 5 days (all P ＜ 0.05).It was shown by ROC curve that area under ROC curve (AUC) for Qs/Qt evaluating the prognosis on the 5th day was 0.958,and 95％ confidence interval (95％CI) was 0.777-0.999 (P ＜ 0.000 1,Z =13.13).When the cut-off value of Qs/Qt was 28％,sensitivity and specificity were 83.3％ and 90.0％,respectively.AUC for PaO2/FiO2 evaluating the prognosis on the 5th day was 0.790,and 95％CI was 0.577-0.928 (P =0.002 1,Z =3.08).When the cut-off value of PaO2/FiO2 was 223 mmHg,sensitivity and specificity were 69.2％ and 81.8％,respectively.Conclusion Dynamic Qs/Qt surveillance can help physician to analyze the changes of the patient's condition,and it was better than PaO2/FiO2,and can be an important evaluation indicator of prognosis for ARDS patients.

The incidence of aduIt obesity,diabetes,hyperIipidemia and hypertention has been rising dramaticaIIy in recent years. Obesity and overweight have become a significant pubIic heaIth probIem worIdwide. Though obesity is caused by compIex interactions between genetic,behavioraI,and environ-mentaI factors,its etioIogy is stiII uncIear. There is growing evidence that exposure to bisphenoI A(BPA) during prenataI and neonataI or adoIescence periods Ieads to much body mass gain. In addition,in epi-demioIogicaI studies,the association between BPA exposure and obesity and type 2 diabetes has been found. The potentiaI mechanism may be attributed to promoted differentiation and function in adipocytes via aIteration of a number of genes. BPA may act aIso through other mechanisms. It can directIy bind to nucIear receptors acting as agonists or antagonists and indirectIy disrupt hormone IeveIs by inhibiting enzymatic activity or by activating expression of the P450 enzymes. This review is focused on the effects of estrogenic endocrine disrupting chemicaIs such as BPA on the deveIopment of obesity.

Objective To analyse the influencing factors of quality of life (QOL)among postoperative children with congenital anorectal malformation (ARM), so as to provide evidence for developing comprehensive interventions and improve QOL of children with ARM.Methods The QOL of 100 children aged at 2 and 5 years old were evaluated by using the Chinese version of PedsQLTM4.0 scale, and the total and 4 dimensions scores of QOL were calculated.Univariate and multiple stepwise regression model was applied to analyse the influencing factors of the QOL.Results The results of univariate analysis among ARM children aged at 2 years old showed that the clinical classification, bowel disorders and family residence have different influence on QOL scores of the 4 dimensions and total scale (P ＜ 0.05).The results of univariate analysis among ARM children aged at 5 years old showed that the clinical classification, bowel disorders and maternal education had different influence on QOL scores of the 4 dimensions and total scale (P ＜ 0.05).The results of multiple stepwise regression model among ARM children aged at 2 years old showed that the major influence factor of QOL scores in physical function was family residence and bowel disorders(P ＜ 0.05), the major influence factor of QOL scores in social functioning was bowel disorders(P ＜ 0.05), the major influence factor of the total scores was bowel disorders and family residence(P ＜0.05).The results of multiple stepwise regression model among ARM children aged at 5 years old showed that the major influence factor of QOL scores in physical function was maternal occupation and clinical classification(P ＜ 0.05), the major influence factor of QOL scores in emotional functioning was bowel disorders(P ＜ 0.05) ,the major influence factor of QOL scores in social functioning was clinical classification and bowel disorders (P ＜ 0.05), the major influence factor of QOL scores in school performance was maternal occupation(P ＜ 0.05), the major influence factor of total scores was bowel disorders and clinical classification(P ＜ 0.05).Conclusion Family residence and bowel disorders have effct on QOL of ARM children aged at 2 years old.Maternal occupation, clinical classification and bowel disorders have effct on QOL of ARM children aged at 5 years old.We should take positive interventions on these influencing factors to improve QOL of children with ARM.

Objective: High mobility group box 3 (HMGB3) plays an important role in the development of various cancer. This study aims to explore whether HMGB3 regulates cervical cancer (CC) progression and elucidate the underlying mechanism. Methods: HMGB3 expression in clinical patients' tumor samples were determined by real-time quantitative polymerase chain reaction (qRT-PCR) and western blot. HMGB3 overexpression/knockdown were used to investigate its function. Cell apoptosis and cycle were detected by Annexin V/PI staining and flow cytometry. In vivo tumor model was made by subcutaneous injection of HeLa cells transfected with shRNAs targeting HMGB3 (shHMGB31) into the flank area of nude mice. Western blot was used to detect the levels of β-catenin, c-Myc, and matrix metalloproteinase-7 (MMP-7) in Hela and CaSki cells transfected with sh-HMGB3 or shRNAs targeting β-catenin. Results: Both messenger RNA and protein levels of HMGB3 were upregulated in CC tissues from patients. High expression level of HMGB3 had positive correlation with serosal invasion, lymph metastasis, and tumor sizes in CC patient. Functional experiments showed that HMGB3 could promote CC cell proliferation both in vitro and in vivo. The expression levels of c-Myc and MMP-7 were increased, resulting in regulating cell apoptosis, cell cycle, and activating Wnt/β-catenin pathway. Conclusions Our data indicated that HMGB3 may serve as an oncoprotein. It could be used as a potential prognostic marker and represent a promising therapeutic strategy for CC treatment.

BACKGROUND:Currently,numerous experiments delve into the intricate anatomy and biomechanical behavior of distinct segments of the supraspinatus muscle.However,the impact of shoulder joint stress resulting from damage to various regions of this muscle remains a scarcely explored domain.Understanding the repercussions of supraspinatus muscle injuries across different regions on the stress distribution and magnitude of articular cartilage and the glenoid is crucial for providing some theoretical support for clinical diagnosis and treatment. OBJECTIVE:To ascertain the maximum stress values by simulating different degrees of supraspinatus muscle rupture on the humeral cartilage surface,glenoid lip,and glenoid cartilage joint surface using three-dimensional finite element software. METHODS:Normal and healthy shoulder joint CT or MRI scans were processed through Mimics and Geomagic to extract molds.Subsequently,models were constructed via Solidworks.Varying degrees of supraspinatus muscle damage were simulated for each model to mimic fractures in different regions.Finally,Ansys,mechanical software,was employed for three-dimensional finite element biomechanical analysis,calculating stress values for the humeral cartilage surface,glenoid lip,and glenoid cartilage joint surface. RESULTS AND CONCLUSION:(1)With worsening degrees of supraspinatus muscle injury,the stress on the shoulder joint cartilage surface and glenoid lip escalated.(2)Among various regions,the anterior part of the supraspinatus muscle exhibited paramount significance.(3)While supraspinatus muscle fractures of differing degrees impacted the magnitude of cartilage stress on the glenoid labial surface,the stress distribution remained constant.(4)It is indicated that during the initial stages of horizontal abduction of the shoulder joint,the anterior region assumes a pivotal role,followed by the posterior deep region.Injury to the anterior part of the supraspinatus muscle leads to a significant surge in stress within the shoulder joint's soft tissue,potentially causing damage to the top of the glenoid lip and the anterior part of the glenoid cartilage.

Objective To explore effect and nursing of Dezocine and Sufentanil on self-controlled vein analgesia after laparotomy.Methods 60 patients undergoing abdominal surgery were randomly divided into Dezocine group (group D),Sufentanil group (group S),and Dezocine and Sufentani group (group DS).Analgesic,sedative effect of three drugs after 3 postoperative hours,6 h,12 h,24 h and 48 h were compared.Adverse reactions such as nausea,vomiting, dizziness,respiratory depression were recorded.Satisfaction of three groups of patients on the post-operative analgesia effect was evaluated.Results After 6 postoperative hours,12 h,24 h and 48 h,the difference of VAS score of group DS was not statistically significant compared with the group S (P >0.05).And the score of group DS and group S were lower than that in the group D (P <0.05).Analgesia satisfaction of group DS was higher than that of group D and group S,and the difference was statistically significant (P <0.05).The incidence of adverse reactions of group DS was lower than that of group D and S ,and the difference was statistically significant (P <0.05).Conclusion The analgesia and sedative effect of the Dezocine and Sufentanil after abdomi-nal surgery is better than drug usage alone,and adverse reactions decreases.Preoperative and post-operative education about analgesic effect,timely dealing with adverse reactions can increase pa-tients’satisfaction and improve the quality of life of the patients.

Objective:To construct endocrinology nursing subspecialty model and explore its clinical effect.Methods:In December 2018, the organization structure of endocrinology nursing subspecialty was constructed in the Drum Tower Hospital Affiliated of Nanjing University Medical School and applied in clinic. In this model, the data of 2018 were taken as the data before application and the data of 2020 were taken as the data after application. The comprehensive ability of nurses, nurse satisfaction, related nursing workload and scientific research ability of nurses were compared before and after the application of the model.Results:After the application of subspecialty nursing mode, nurses′ comprehensive ability score was (92.00 ± 2.36) points. Compared with (84.25 ± 3.24) points before implementation, the difference was statistically significant ( t=-9.46, P<0.01); nurses′ satisfaction evaluations including specialty development (7.92 ± 1.41), self-quality improvement (8.00 ± 1.69), work pressure (6.42 ± 2.67), salary and welfare (3.96 ± 0.85), compared with (5.79 ± 2.31), (6.17 ± 2.82), (8.33 ± 1.50), (2.88 ± 1.59) before implementation, the difference was statistically significant ( t values were -3.86--2.73, all P<0.05). The annual workload of related nursing increased and the scientific research ability of nurses was improved. Conclusions:The application of endocrinology nursing subspecialty mode is beneficial to improve nurses′ comprehensive ability of clinical work, improve the level of specialized nursing, improve the quality of nursing service and promote the improvement of economic benefits, which is worthy of clinical promotion.

Objective To compare the effects of fluid therapy by "measurement" water dispenser and routine fluid therapy on standard fluid therapy among patients with percutaneous coronary intervention (PCI) in coronary care unit (CCU). Methods A total of 204 patients with PCI were divided into observation group (n=102) and control group (n=102) by random number table. Patients in the observation group received drinking water plan according to regulatory requirements using the self-designed "measurement" water dispenser. Patients in the control group accepted nursing plan of routine drinking fluid therapy. This study compared the qualified rate of standardized drinking water, patient satisfaction, renal function and the incidence of contrast-induced nephropathy (CIN) three days after intervention between two groups. Results There were 102 (100.00%) qualified patients drinking water according to stipulations in the observation group, while there were 68 (66.67%) in the control group. The qualified rate of drinking water in the observation group was higher than that in the control group with a significant difference (χ2=38.4, P<0.01). There were two patients with contrast induced nephropathy in the observation group, and eight patients with contrast induced nephropathy in the control group (χ2=4.2,P=0.04). Conclusions The effect of fluid therapy by "measurement" water dispenser supplemented with diversified education is satisfactory among patients with PCI in CCU.
