Objective To explore the clinical features, diagnosis and treatment of Wunderlich syndrome (WS).Methods Fifteen patients with WS were included from September 2008 to February 2014, and their clinical features, diagnosis and treatment were retrospectively reviewed.The most common clinical manifestations were flank or abdominal pain (15/15), hypovolemic shock (5/15), gross hematuria (4/15) and percussion pain on kidney region ( 15/15 ) .Laboratory tests showed anemia ( 9/15 ) and coagulation abnormalities (5/15).Five of 15 cases were critical patients with moderate to severe shock ( systolic blood pressure≤90 mmHg, 1 mmHg =0.133 kPa ) accompanied with severe anemia ( Hb <60 g/L ) and coagulation abnormalities.Results In the acute stage, the diagnostic ratios of ultrasonography and contrast enhanced CT for WS were 11/15 and 15/15, and cause determination ratios were 4/15 and 10/15, respectively.The latter was significantly higher than the former ( P <0.05 ) .Contrast enhanced MRI was performed in 5 cases, and the results were identical to those of CT.According to the causes made by emergent imaging, critical patients underwent emergent operations or renal arteriography plus selective arterial embolization, and the other patients underwent conservative management, emergency operations, or renal arteriography plus selective arterial embolization, respectively.The causes of WS included angiomyolipoma (8 cases), renal cell carcinoma (3 cases), metastatic tumor of lung cancer (1 case) and renal cyst (3 cases) in this study.The mean follow-up period was 34 months.One critical patient died, and all the other patients were cured or relieved.Conclusions WS has no specific clinical features.Contrast enhanced CT or MRI is the main approach for diagnosis and cause determination, which is superior to ultrasonography.Treatments for WS vary according to severity classification and imaging diagnosis.

Based on the hospital information systems and the hospital network,a software for patients with peripherally inserted central catheter (PICC) was developed and applied in clinical practice,which achieved the share of PICC information within the hospital,saved nursing time effectively,made the clinical data more standardized,systematical and objective.

Objective? To explore the effects of psychological flexibility intervention on the symptoms and self-management efficacy of patients after hepatic arterial infusion chemoembolization. Methods? By convenient sampling, a total of 90 patients with hepatocellular carcinoma who had undergone hepatic arterial transcatheter chemoembolization in the First Affiliated Hospital of Zhengzhou University from January to February 2018 were selected. By random number table method, they were divided into the observation group and the control group, with 45 participants in each group. The control group received routine nursing intervention, and the observation group received psychological flexibility intervention, both for 2 weeks. Before and after the intervention, the Memorial Symptom Assessment Scale (MSAS) and the Chinese version of the Strategies Used People to Promote Health (SUPPH) were used to assess the symptomatic distress and self-management efficacy of the two groups in order to evaluate the effects of the intervention. Results? There were no significant statistical differences in the average scores of physical symptoms, psychological symptoms, distressed index, and main clauses of MSAS before intervention between the two groups(P＞0.05). After intervention, the physical symptoms of the patients in both groups had no statistical difference compared with those pre-intervention (P＞0.05), while the average scores of psychological symptoms, distress index, main clauses of MSAS were all lower than those pre-intervention with statistical significance (P＜0.05). In the observation group, the average scores of psychological symptoms, distress index, and main clauses of MSAS were lower than the control group after intervention with statistical significance (P＜ 0.01). Before intervention, the total score of SUPPH and the score from each dimension in the scale between two groups had no statistical difference (P＞ 0.05). After intervention, the total score of SUPPH and the scores from each dimension increased with statistical significance (P＜0.05) while no statistical significance was found in the control group (P＞0.05). The total score of SUPPH and the scores from each dimension were all higher than the control group with statistical significance (P＜0.01). Conclusions? The psychological flexibility intervention can effectively reduce the patients' psychological distress after chemoembolization, and promote their self-management efficiency,therefore is worth promoting in the clinical practice.

Objective:To observe the application value of virtual cognitive rehabilitation training in patients with mild cognitive impairment induced by transcatheter arterial chemoembolization (TACE) of liver neoplasms.Methods:By the convenience sampling method, a total of 126 liver neoplasms patients with mild cognitive impairment induced by TACE who were admitted and treated in the First Affiliated Hospital of Zhengzhou University from May 2015 to May 2019 were selected. They were randomly divided into the observation group and the control group, with 63 cases in each group. The control group was given routine cognitive intervention while the observation group was given virtual cognitive rehabilitation training, and the intervention lasted for 2 months. Montreal Cognitive Assessment Scale (MoCA) , Activities of Daily Living (ADL) Scale and Chinese version of Strategies Used by People to Promote Health (SUPPH) Scale were used to evaluate the cognitive function, ability of daily living and self-efficacy level of patients before and after intervention between two groups.Results:There was no statistically significant difference in MoCA, ADL, and SUPPH scale scores of patients between the two groups before the intervention ( P> 0.05) . After 2 months of intervention, the total score of the MoCA Scale (21.70 ± 5.27) and the total score of the SUPPH Scale (88.23 ± 21.43) in the observation group were higher than those in the control group, and the differences were statistically significant ( t=2.949, 4.509; P<0.05) . After intervention, the score of the ADL Scale in the observation group was (16.03±3.11) and that in the control group was (18.06±2.97) , and the difference was statistically significant ( t=3.747, P<0.05) . Conclusions:Virtual cognitive rehabilitation training can improve the cognitive function of liver neoplasms patients with mild cognitive impairment caused by TACE and improve the activity of daily living and self-efficacy.

Objective:To explore and analyze the application of smoking cessation intervention based on timing theory in elderly patients with chronic obstructive pulmonary disease (COPD) complicated with tobacco dependence.Methods:A total of 120 elderly patients with COPD combined with tobacco dependence who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2020 to March 2021 were selected by the convenient sampling method. They were divided the control group and the observation group according to the random number table method, with 60 cases in each group. The control group was given routine intervention, while the observation group was given smoking cessation intervention based on timing theory. The smoking cessation rate, nicotine dependence degree, clinical symptom score and lung function recovery were compared between the two groups.Results:Three months after discharge, the nicotine dependence degree of observation group was lower than that of control group, and the difference was statistically significant ( P<0.05). The smoking cessation rates of 1, 2 and 3 months after discharge in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.05). Three months after discharge, PEF of observation group was higher than that of control group, and the difference was statistically significant ( P<0.05). The clinical symptom score of the observation group at 3 months after discharge was lower than that of the control group, and the difference was statistically significant ( P<0.05) . Conclusions:The application of smoking cessation intervention based on timing theory in elderly patients with COPD complicated with tobacco dependence can improve the smoking cessation rate, reduce the degree of nicotine dependence of patients and effectively alleviate COPD related clinical symptoms.

Objective:To evaluate the role of Z-DNA-binding protein 1 (ZBP1)/receptor-interacting protein kinase 1 (RIPK1) signaling pathway in lipopolysaccharide (LPS)-adenosine triphosphate (ATP)-induced pyroptosis in macrophages of mice.Methods:The RAW264.7 macrophages from mice were routinely cultured and divided into 6 groups ( n=9 each) using a random number table method: control group (group C), LPS-ATP group, LPS-ATP+ transfection negative control scRNA group (group LPS-ATP+ scRNA), LPS-ATP+ ZBP1 small interference RNA group (group LPS-ATP+ siRNA), LPS-ATP+ dimethyl sulfoxide group (group LPS-ATP+ DSMO), and LPS-ATP+ RIPK1 inhibitor nec-1 group (group LPS-ATP+ nec-1). The siRNA technique was used to inhibit the expression of ZBP1 in group LPS-ATP+ siRNA. The RIPK1 inhibitor nec-1 was given to inhibit the expression of RIPK1 protein in group LPS-ATP+ nec-1. Group C was routinely cultured. Cells were incubated with 10 μg/ml LPS for 24 h, then 5 mmol/L ATP was added, and the cells were incubated for 30 min to develop the cell pyroptosis model in the remaining 5 groups. The cell survival was detected by the CCK-8 assay. The concentrations of interleukin-1beta (IL-1β), IL-6, IL-18 and tumor necrosis factor-alpha (TNF-α) in cell supernatant were determined by enzyme-linked immunosorbent assay. The pyroptosis was determined by propidium iodide fluorescence staining. Western blot was used to detect the expression of ZBP1, RIPK1, caspase-1 and GSDMD. Results:Compared with group C, the cell survival rate was significantly decreased, the cell pyroptosis rate and concentrations of IL-1β, IL-6, IL-18 and TNF-α in the supernatant were increased, and the expression of ZBP1, RIPK1, caspase-1 and GSDMD was up-regulated in group LPS-ATP ( P<0.05). Compared with group LPS-ATP, no significant change was found in the parameters mentioned above in group LPS-ATP+ scRNA and group LPS-ATP+ DSMO ( P>0.05). Compared with group LPS-ATP+ scRNA, the cell survival rate was significantly increased, the cell pyroptosis rate and concentrations of IL-1β, IL-6, IL-18 and TNF-α in the supernatant were decreased, and the expression of ZBP1, RIPK1, caspase-1 and GSDMD was down-regulated in group LPS-ATP+ siRNA ( P<0.05). Compared with group LPS-ATP+ DMSO, the cell survival rate was significantly increased, the cell pyroptosis rate and concentrations of IL-1β, IL-6, IL-18 and TNF-α in the supernatant were decreased, the expression of ZBP1, caspase-1 and GSDMD was down-regulated ( P<0.05), and no significant change was found in the expression of ZBP1 in group LPS-ATP+ nec-1 ( P>0.05). Conclusions:Activation of ZBP1/RIPK1 signaling pathway is involved in LPS-ATP-induced pyroptosis in macrophages of mice.

ObjectiveTo explore the impact of different types of virtual reality environments balance exercise on human balance and posture control. MethodsFrom March to April, 2022, 30 male students from Dalian University of Technology were recruited to accept VR balance training of dynamic background (dynamic VR training) and static background (static VR training), respectively, with an interval of one week. They were measured the average moving speed of the center of pressure of human body under eight conditions before and after training, namely open-eye floor standing, close-eye floor standing, static VR background floor standing, dynamic VR background floor standing, open-eye sponge pad standing, close-eye sponge pad standing, static VR background sponge pad standing, and dynamic VR background sponge pad standing. Meanwhile, the weight of human body sensation was calculated. ResultsBefore training, the average movement speed of center of pressure was higher under the static VR than under open-eye (|t| > 2.811, P < 0.01), and lower than under close-eye (t > 3.279, P < 0.01) on both planes; while it was higher under dynamic VR than under close-eye (|t| > 4.830, P < 0.001). After dynamic VR training, the average movement speed of center of pressure increased under open-eye stable floor standing (t = 2.305, P < 0.05), decreased under close-eye on both planes (t > 3.405, P < 0.01), and decreased under static and dynamic VR on both planes (|t| > 3.285, P < 0.01). After static VR training, the average movement speed of center of pressure increased under open-eye floor standing (t = 2.224, P < 0.05), decreased under close-eye sponge pad standing (t = 2.223, P < 0.05), and decreased under dynamic VR on both planes (|t| > 2.380, P < 0.05). The weight of vision decreased after training (t > 4.132, P < 0.001), and the visual weight under normal proprioception was less after dynamic VR training than after static VR training (t = 3.611, P < 0.01). ConclusionUnder static VR background, the balance stability is poorer than under open-eye, but stronger than under close-eye. Under dynamic VR background, the balance stability is poorer under close-eye. VR balance training may decrease the stability without interference, but improve the stability under interference, which may result from reducing the dependence on visual sensation and strengthening the use of vestibular sensation, especially after VR training with dynamic background.

Objective:To determine the effects of menopausal stage, age and other associated risk factors on symptoms of anxiety and depression among women in a community in Beijing.Methods:This study was a community-based prospective cohort. Participants who had transitioned through natural menopause, completed two or more depressive and anxiety symptoms evaluations, aged 35 to 64 years, and did not use hormone therapy were selected from the Peking Union Medical College Hospital aging longitudinal cohort of women in midlife to this analysis. The primary outcome variables were depressive and anxiety symptoms, assessed by hospital anxiety and depression scale (HADS). The generalized estimation equation was used in the statistical analysis.Results:Followed up from 2006 to 2014, 430 women and 2 533 HADS assessments were retained in the cohort. Depressive symptoms were more common than anxiety symptoms during all menopausal stages. The incidences of depressive and anxiety symptoms were 14.5% (19/191) and 3.1% (4/191) in the premenopausal -3 stage, respectively. The incidence increased in both menopausal transition and postmenopausal stage, with the highest incidence in the +1c stage [20.6% (155/751) and 8.8% (66/751), respectively]. However, these differences were not statistically significant (all P>0.05). Depressive symptoms were highest in the ≥60-<65 age group [20.8% (74/355)], and anxiety symptoms were highest in the ≥50-<55 age group [8.2% (62/754)]; but there were no statistical significances between different age groups and depressive and anxiety symptoms (all P>0.05). Multivariable analysis showed that high body mass index, low education status, and poor health status were independently associated with depressive symptoms (all P<0.05), and that poor health status, trouble falling asleep, and early awakening were independently associated with anxiety symptoms (all P<0.01). Conclusions:Depressive and anxiety symptoms are more common during menopausal transition and postmenopausal stage compared with reproductive stage. Depressive symptoms are more common than anxiety symptoms. To screen and assess depressive and anxiety symptoms in perimenopausal women is essential, especially for women with high risk factors.

Objective: To detect the effect of the ball compressor method to prevent jugular vein malposition in peripherally inserted central catheter insertion (PICC). Methods: Convenient sampling method was used to recruit 1 358 patients with PICC insertions during October 2017 to September 2018 in Second affiliated hospital Zhejiang University, school of medicine. 681 were included in experimental group, and 677 patients were included in control group. The control group used traditional turning head to the PICC insertion side or fingers compression to block the entrance of jugular vein to prevent jugular vein malposition in control group. While in experimental group, rugby- shape ball compression were used to block jugular vein to reduce jugular vein malposition. The rate of jugular vein malposition in the first try of catheterization was calculated in both groups. Results: The rate of jugular vein malposition in the first try of catheterization was 19.1%(130/681) in experimental group and 23.5% (159/677) in control group respectively. There is statistically significant difference between two groups (χ²=3.917, P=0.047 8). Conclusion Rugby- shape ball compression could reduce jugular vein malposition in the first try of catheterization effectively.

Objective To establish macrosomia risk prediction models based on a cohort study, and to analyze and compare the results. Methods The research subjects were the pregnant women of the Chinese Pregnant Women Cohort Study. The general demographic information and clinical data of pregnant women were collected through the questionnaire and physical examination, and the related outcomes of newborns were obtained by follow-up. The dataset was divided into training set and test set by a 3:1 ratio. Multivariate logistic regression analysis (LR) and random forest algorithm (RF) were used to construct macrosomia risk prediction models in the training set, and the models were verified in the test set. The prediction efficiency of the models was evaluated by Kappa and the area under the receiver operating characteristic curve (ROC). Results Among 5544 pregnant women, 397 women delivered macrosomia, and the incidence of macrosomia was 7.16%. Among the pregnant women who delivered macrosomia, 10.08% (40/397) were over 35 years old, 27.46% (109/397) were overweight or obese, and 60.96% (242/397) were excessive gestational weight gain (GWG). LR was used to establish a macrosomia risk prediction model to predict the test set, with the accuracy of 0.716, the sensitivity of 0.719, the specificity of 0.715, the Kappa value of 0.428, the Yoden index of 0.393, and the AUC of 0.796 (95% CI: 0.777-0.815). RF was used to construct a risk prediction model to predict the test set, with the accuracy of 0.819, the sensitivity of 0.782, the specificity of 0.846, the Kappa value of 0.629, the Yoden index of 0.439, and the AUC of 0.897 (95% CI: 0.883-0.910). Conclusion The prediction effect of the two models is satisfactory. The random forest algorithm has a higher predictive effect on the risk of macrosomia in this cohort, but the multivariate logistic regression analysis can directly explain the influencing factors of the macrosomia. It is suggested to integrate the advantages of the two models in the future, so that they can play a more important role in macrosomia risk prediction.
