Objective:To investigate the effect of early pulmonary rehabilitation (PR) training on the improvement of respiratory function in patients with acute respiratory distress syndrome (ARDS) after weaning of invasive mechanical ventilation in the intensive care unit (ICU).Methods:The retrospective cohort research method was used. The clinical information of adult patients with ARDS receiving invasive mechanical ventilation admitted to the ICU of Qingdao Municipal Hospital from January 2019 to March 2023 was collected. The patients were divided into a control group and an observation group according to off-line training program. The control group received traditional training after weaning, and the observation group received the early PR training after weaning. Other treatments and nursing were implemented according to the routine of the ICU. The scores of the short physical performance battery (SPPB) on day 3-day 6 of the weaning training, respiratory muscle strength, level of interleukin-6 (IL-6), number of aspirations of sputum after weaning, length of stay after weaning, rehospitalization rate within 6 months after discharge, and pulmonary function indicators at discharge and 3 months after discharge [peak expiratory flow (PEF), forced expiratory volume in one second/forced vital capacity ratio (FEV1/FVC), and vital capacity (VC)] of the two groups of patients were compared. The Kaplan-Meier survival curve was drawn to analyze the cumulative survival rate of patients 6 months after discharge.Results:A total of 50 of which 25 cases received the traditional training after weaning, 25 cases received the early PR training after weaning. There was no significant difference in gender, age, acute physiology and chronic health evaluationⅡ (APACHEⅡ), oxygenation index upon admission, etiological diagnosis of ARDS upon admission, time of invasive ventilation, mode of invasive mechanical ventilation, pulmonary function indicators at discharge, and other baseline data of the two groups. The SPPB questionnaire scores and respiratory muscle strength in both groups were increased gradually with the extended offline training time, the serum level of IL-6 in both groups were descend gradually with the extended offline training time, especially in the observation group [SPPB questionnaire score in the observation group were 7.81±0.33, 8.72±0.53, 9.44±0.31, 10.57±0.50, while in the control group were 7.74±0.68, 8.73±0.37, 8.72±0.40, 9.33±0.26, effect of time: F = 192.532, P = 0.000, effect of intervention: F = 88.561, P = 0.000, interaction effect between intervention and time: F = 24.724, P = 0.000; respiratory muscle strength (mmHg, 1 mmHg≈0.133 kPa) in the observation group were 123.20±24.84, 137.00±26.47, 149.00±24.70, 155.40±29.37, while in the control group were 129.00±20.34, 126.00±24.01, 132.20±25.15, 138.60±36.67, effect of time: F = 5.926, P = 0.001, effect of intervention: F = 5.248, P = 0.031, interaction effect between intervention and time: F = 3.033, P = 0.043; serum level of IL-6 in the observation group were 80.05±6.81, 74.76±9.33, 63.66±10.19, 56.95±4.72, while in the control group were 80.18±7.21, 77.23±9.78, 71.79±10.40, 66.51±6.49, effect of time: F = 53.485, P = 0.000, effect of intervention: F = 22.942, P = 0.000, interaction effect between intervention and time: F = 3.266, P = 0.026]. Compared with the control group, the number of aspirations of sputum after weaning of patients in the observation group significantly decreased (number: 22.46±1.76 vs. 27.31±0.90), the length of ICU stay after weaning significantly became shorter (days: 6.93±0.95 vs. 8.52±2.21), and the rehospitalization rate within 6 months after discharge significantly decreased [20.00% (5/25) vs. 48.00% (12/25)]. There were significant differences. The pulmonary function indicators 3 months after discharge of two groups of patients significantly increased compared with those at discharge and those of the observation group were significantly higher than those of the control group [PEF (L/min): 430.20±95.18 vs. 370.00±108.44, FEV1/FVC ratio: 0.88±0.04 vs. 0.82±0.05, VC (L): 3.22±0.72 vs. 2.74±0.37, all P < 0.05]. The Kaplan-Meier survival curve showed that the cumulative survival rate of patients 6 months after discharge of patients in the observation group was significantly higher than that of patients in the control group [76.9% vs. 45.5%, hazard ratio ( HR) = 0.344, P = 0.017]. Conclusion:Early PR training can significantly improve the respiratory function of patients with ARDS after weaning of invasive mechanical ventilation. Continuous active respiratory training after discharge can improve the respiratory function of patients and effectively decrease mortality.

Objective: To investigate the effects of interleukin ( IL) -10 on the proliferation of HaCaT cells and CaCl2 induced expression of differentiation markers and its possible molecular mechanisms． Methods: HaCaT cells were treated with various concentrations of IL-10 (0，3，10，30 ng / ml) for different time (0，24，48，72 h) ，cell proliferation was measured using MTS，and cell cycle was determined by flow cytometry．HaCaT cells were pretreated with IL-10 (final concentration 10 ng / ml) for 1 h，then incubated with or without CaCl2 (final concentration 1. 2 mmol / L) for 24，48，72 h ，Western blot was performed to detect the effect of IL-10 on the expression of HaCaT keratinocyte differentiation markers．After pretreatment of HaCaT cells with PD98059，an inhibitor of mitogen-activated kinase-ERK1 /2，and LY294002，an inhibitor of phosphatidylinositol kinase-serine / threonine kinase (PI3K-AKT) ，the total RNA and proteins were extracted separately，real time quantitative polymerase chain reaction (RT-qPCR) and Western blot were used to examine the influence of IL-10 on the expression of differentiation markers (Keratin1，Keratin5，Involucrin) . Results : MTS results revealed that IL-10 (30 ng / ml and lower doses) did not alter the proliferation of HaCaT cells in 72 h．Flow cytometry analysis demonstrated that IL-10 had no significant influence on cell cycle progression．The results of Western blot showed that IL-10 upregulated the expression of differentiation markers Involucrin，while there was no significant effect on Keratin1 and Keratin5 ．Mechanism research analysis demonstrated that IL-10 could activate ERK1 /2 and AKT ，increase their phosphorylation levels ; RT-qPCR and Western blot results showed that PD98059 and LY294002 partially blocked IL-10 induced Involucrin expression． Conclusion At a particular concentration range，IL-10 has little effect on HaCaT proliferation ，but it partially upregulates the expression of differentiation marker Involucrin via the MAPKs-ERK1 /2 and PI3K-AKT pathways.

We describe a case of fetal sacrococcygeal teratoma detected by ultrasound at 14 gestational weeks. The tumor was classified as "type Ⅰ" by ultrasonography combined with MRI. The cystic part accounted for over 60% of the mass before 26 weeks and ruptured spontaneously at 28 weeks. The size of the tumor was 12.8 cm×9.7 cm×12.3 cm at 36 +5 gestational weeks. A female newborn was born through cesarean section at 37 weeks of gestation and had the tumor removed surgically on the postnatal day 4. Postoperative follow-up showed that the neonate had a good prognosis without physiological dysfunction.

We describe a rare case of fetal mediastinal capillary hemangioma presenting as pleural effusion and a huge pleural occupying lesion during late pregnancy. The patient was admitted at 36 +3 weeks of gestation, with a fetal chest occupying lesion for 11 days. Routine prenatal ultrasound and MRI indicated right pleural effusion and a huge chest occupying lesion in the fetus. The woman was administered oxytocin and delivered a live baby boy at 36 +5 weeks of gestation. The baby was diagnosed as mediastinal hemangioma by postnatal CT, angiography and 3D reconstruction and was discharged after oral propranolol treatment. However, he was readmitted one month after birth due to "pneumonia and tachypnea". After multidisciplinary consultation, the baby underwent a right-side thoracic mediastinal mass resection, and a mediastinal capillary hemangioma was confirmed by pathology. The child continued taking propranolol orally and received regular follow-up and rehabilitation after the operation up to 7 months old, by which time no obvious abnormalities were found.

Objective With multi?center investigation, to assess the life quality of patients with maintained hemodialysis (MHD) in Liaoning Province and to explore the relationship among the mineral metabolism, the life quality of the patients with MHD, and the repeated hospitalization within the latest three years. Methods 1192 patients with hemodialysis (at least 3 months) from January to March in 2015 at ten blood purification centers in Liaoning Province were selected for the cross?————————sectional survey. The Kidney Health?related Quality of Life (HRQOL) version 1.3 was used to evaluate the MHD patients' life quality. The total length of hospitalization was divided into four groups: 0 days, 3 to 15 days, 16 to 30 days and above 30 days. Results When serum calcium value ranged from 2.1 to 2.5 mmol/L, kidney?disease component summary (KDCS), mental component summary (MCS), physical component summary (PCS) and SF?36+KDCS corresponded to a higher value (P<0.05). When serum phosphorus value ranged from 1.13 to 1.78 mmol/L, KDCS and SF?36+KDCS corresponded to a higher value (P<0.05). When the calcium phosphorus product value ranged from 40.68 to 49.94, MCS corresponded to a higher value (P<0.05). KDCS showed a linear correlation with age (P<0.001), dialysis age, serum calcium (less than or equal to 2.5 mmol/L) (P<0.05); PCS showed a linear correlation with age (P<0.001) and dialysis age (P<0.05); SF?36+KDCS showed a linear correlation with age (P<0.001), and serum calcium (less than or equal to 2.5 mmol/L) (P<0.05), while age and dialysis age were negatively correlated. The hospitalization days showed a linear correlation with age, dialysis age (P<0.001) and serum phosphorus, calcium phosphorus product value (P<0.05), while dialysis age and calcium phosphorus product value were negatively correlated. Among different groups of total hospitalization days in three years, age, hemodialysis age, serum calcium, serum phosphorus, calcium?phosphorus product value and quality of life values were all statistically significant (P<0.05). Conclusions The life quality of patients with MHD were correlated with serum calcium, phosphorus, calcium and phosphorus product value, iPTH, dialysis age and age, while age and dialysis age were of negative correlation. The total number of hospitalization days in 3 years was closely linearly correlated with age and dialysis age, significantly correlated with serum phosphorus, calcium and phosphorus product value, while dialysis age, calcium and phosphorus product value were in a negative correlation. The total number of hospitalization in 3 years was correlated with the patients' age, dialysis age, serum calcium, serum phosphorus, calcium and phosphorus product value and quality of life.

Objective To evaluate the effects of sevoflurane postconditioning on the oncosis and apoptosis in cardiomyocytes during ischemia-reperfusion (I/R) in isolated rat hearts and the role of extracellular signalregulated protein kinase 1/2 (ERK1/2) signal transduction pathway in it.Methods Seventy-two isolated rat hearts perfused in a Langendorff apparatus were randomly divided into 6 groups (n =12 each) using a random number table:sham operation group (group S),myocardial I/R group (group I/R),sevoflurane postconditioning group (group SP),PD98059 vehicle dimethyl sulfoxide (DMSO) group (group DMSO),selective ERK1/2 inhibitor PD98059 group (group PD),and sevoflurane postconditioning + PD98059 group (group SP + PD).The hearts were subjected to ischemia for 30 min followed by 2 h reperfusion in the other groups except group S.In SP,DMSO and PD groups,the hearts were perfused with K-H solution saturated with 3.0％ sevoflurane,DMSO (＜0.2％) and PD98059 (20 μmol/L),respectively,for 15 min starting from the end of ischemia until 15 min of reperfusion,and then with plain K-H solution for 105 min.In group SP+ PD,the hearts were perfused with K-H solution saturated with 3.0％ sevoflurane and PD98059 for 15 min starting from the end of ischemia until 15 min of reperfusion.Myocardial infarct size and expression of porimin and caspase-8 proteins (by Western blot) were measured at the end of reperfusion.Results Compared with S group,the myocardial infarct size was significantly increased,and the expression of porimin and caspase-8 proteins was up-regulated in the other groups (P ＜ 0.05).Compared with I/R group,the myocardial infarct size was significantly decreased,and the expression of porimin and caspase-8 proteins was down-regulated in group SP (P ＜ 0.05),and no significant changes were found in the other groups (P ＞ 0.05).Conclusion Sevoflurane postconditioning can activate ERK1/2 signal transduction pathway and inhibit the oncosis and apoptosis in cardiomyocytes,thus attenuating I/R injury in isolated rat hearts.

Objective To evaluate the effects of sevoflurane postconditioning on the expression of 70 kD aribosomalprotein S6 kinase (p70S6K) during ischemia-reperfusion (I/R) in isolated rat hearts.Methods Pathogen-free male Sprague-Dawley rats,aged 3 months,weighing 270-350 g,were used in the study.Their hearts were excised and perfused in a Langendorff apparatus with K-H solution saturated with 95 ％ O2-5 ％ CO2.Ninety isolated rat hearts with I/R injury were randomly divided into 3 groups (n =30 each):sham operation group (group S),I/R group (group I/R),and sevoflurane postconditioning group (group SP).The hearts were subjected to ischemia for 30 min followed by 2 h reperfusion.In group SP,the hearts were perfused with K-H solution saturated with 3.0％ sevoflurane for 15 min starting from the end of ischemia until 15 min of reperfusion,and then with plain K-H solution for 105 min.At 2 h of reperfusion,myocardial infarct size was measured,the percentage of myocardial infarct size was calculated,and the phosphorylated p70S6K (p-p70S6K)/total p70S6K (tp70S6K) ratio,and cytoplasm,cytochrome C,and caspase-8 expression was measured.Results Compared with group S,the percentage of myocardial infarct size and p-p70S6K/t-p70S6K ratio were significantly increased,the expression of cytochrome C,and caspase-8 was up-regulated,and the expression of cytochrome C was downregulated in I/R group.Compared with I/R group,the percentage of myocardial infarct size was significantly decreased,the ratio of p-p70S6K/t-p70S6K was increased and cytochrome C expression was up-regulated,and the expression of cytochrome C and caspase-8 was down-regulated in SP group.Conclusion Sevoflurane postconditioning can mitigate I/R injury to isolated rat hearts,and up-regulation of p-p70S6K expression,inhibition of transfer of cytochrome C from mitochondria to cytoplasm,and reduced cell apoptosis are involved in the mechanism.
