Objective To explore the influence of self-concealment level on patients'quality of life and clinical curative effect for curing refractory chronic prostatitis(RCP)by high-intensity focused ultrasound(HIFU). Methods Patients of RCP who meet the diagnostic criteria were assessed with the Self-Concealment Scale(SCS), TDL's table of self-assessing quality of life and National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI).The patients whose SCS score were above the average score plus a standard deviation were taken as the high SCS group,and whose SCS Score were below the average score minus a standard deviation were taken as the low SCS group.The scores for CPSI and TDLs table of self-assessing quality of life and the clinical curative effect of the two groups were determined before and after the treatment by HIFU, respectively.Results The SCS score(35.75±10.34) of the RCP patients before HIFU treatment was significantly higher than the norm for male college students(29.20±8.73)(t=4.26,P<0.01).Two and six weeks after the HIFU application,the CPSI of both the high and the low SCS group decreased significantly(P<0.01),and the CPSI of the low SCS group de-creased more greatly than that of the high SCS group(P<0.01).The scores for TDL Life Quality Scale of low SCS group were significantly higher before and after two and six weeks'HIFU treatment than that of high self-concealment group(P<0.01).The TDL quality of life scale score of thelow SCS group increased respectively after two and six weeks'HIFU treatment (P<0.01),while for the high SCS group,this score increased only after six weeks' HIFU treatment(P<0.05).Six weeks after HIFU treatment,the clinical curative effect for the low SCS group was, observably better than that for high self-concealment(P<0.05).The SCS scores was significantly positive with CPSI scores(P<0.01),and significantly negative with the scores of TDL Life Quality Scale (P<0.01).Conclusion The symptom abatement,quality of life and clinical curative effect the RCP patients with a high self-concealment level were respectively worse after the HIFU treatment than that for whom with a low self-concealment level.

BACKGROUND: Surgery is the common therapy for pterygium, and there are several surgical management techniques.OBJECTIVE: To clinically assess the effect of pterygium retro-resection followed by the transposition of conjunctival autograft rich in stem cells.DESIGN: Follow-up of the cases.SETTING: Department of Ophthalmology, the Fourth Affiliated Hospital of China Medical University.PARTICIPANTS: Fifty patients (60 eyes) with pterygium, who were treated in the Fourth Affiliated Hospital of China Medical University from May 2003 to May 2006, were selected. All patients agreed to receive the treatment and participate in the follow-up. The trial was permitted by the Hospital Ethics Committee.METHODS: The head of pterygium was separated from cornea, including the conjunctiva and the underlying proliferating tissue towards lacrimal caruncle until plica semilunaris. The pterygium was totally removed. The adjacent healthy conjunctiva harboring stem cells was transposed to cover the naked sclera. The patients were evaluated following the operation.MAIN OUTCOME MEASURES: ①Epithelization of cornea and conjunctiva; ②reoccurrence of pterygium.RESULTS: ①The epithelium of cornea and conjunctiva in all cases (60 eyes) healed within 1-2 days after the operation. ②The patients were followed for 8-16 months after the sutures were removed. Out of the total of 60 eyes, 26 were followed for 8-12 months and 34 for 13-16 months. The average length of observation was 12 months. Fifty-eight eyes healed completely, and reoccurrence took place in 2 cases.CONCLUSION: Pterygium resection followed by the transposition of adjacent conjunctival autograft harboring stem cells is easy to perform and effective to reduce the recurrence of the lesion.

ObjectiveTo evaluate the effect of high frequency oscillation ventilation (HFOV) vs. conventional mechanical ventilation (CV) on the treatment and prognosis of adult patients with acute respiratory distress syndrome (ARDS).Methods Published articles concerning randomized controlled trials (RCTs) about the effect of HFOV vs. CV on the prognosis of adult patients with ARDS published before May 2014 were retrieved from PubMed, EMBase, Cochrane central registry of controlled trials, CNKI and Wanfang Data. The mortality and data of physiological parameters were analyzed with STATA 12.0, and the mortality rate was also analyzed by trial sequential analysis with TSA 0.9, and the line chart was drawn with Microsoft Office Excel 2003.Results Seven trials with 1 731 patients met the criteria, all of them recorded the physiological parameters data, and mortality rate was mentioned in 6 trials (1 705 patients). Compared with CV, HFOV did not show any statistically significant beneficial effects on mortality [relative risk (RR) = 0.93, 95% confidence interval (95%CI) = 0.70-1.24,P = 0.63], and other clinical outcomes, including survival without mechanical ventilation (RR = 1.05, 95%CI = 0.72-1.54,P = 0.80), survival on mechanical ventilation (RR = 1.23, 95%CI = 0.65-2.35,P = 0.52), or treatment failure (RR = 0.89, 95%CI = 0.50-1.56,P = 0.67). The risk factors of adverse events including hypotension (RR = 0.89, 95%CI = 0.07-10.99,P =0.93), acidosis (RR = 1.05, 95%CI = 0.43-2.56,P = 0.91), and air leakage from ventilator (RR = 0.74, 95%CI = 0.31-1.80,P =0.51) were similar. But the physiologic parameters of patients and parameters of ventilator in HFOV group, including oxygenation index, positive end-expiratory pressure, tidal volume, mean airway pressure, arterial pH, partial pressure of arterial carbon dioxide, fraction of inspired oxygen, ratio of partial pressure of arterial oxygen to fraction of inspired oxygen, were better than those in the CV group. Methods adapted from formal interim monitoring boundaries applied to cumulative Meta-analysis showed that the evidence failed by a considerable degree to meet the standards for forgoing studies, and the necessary sample was 3 874 patients. Trial sequential analysis also showed that the accumulatedZ-score did not cross the traditional boundary (P = 0.05) and interim monitoring boundaries. This result indicated that there was no significant difference between CV and HFOV on mortality before the number of needed sample reached (3 874 cases). We could not get a definitive conclusion with current evidences.ConclusionsCompared with CV, the use of HFOV in ARDS was not associated with a significant reduction in mortality. But the physiologic parameters of patients in HFOV group were better than those in the CV group. More RCTs are needed to draw a definitive conclusion.

Objective To explore the unique relationship between Willis circle and cerebral watershed infarction in a Chinese population. Methods A retrospective analysis of cerebral CT angiography was conducted in 471 non-cere?bral watershed infarctions and 93 MRI-diagnosed cerebral watershed infarctions (CWI)(including External CWI and In?ternal CWI)in Department of Neurology of our hospital and compare the related variations and types of Willis circle be?tween these groups. Results Compared with non-cerebral watershed infarctions, the prevalence of Uni-FTP (short for“fetal type of the Posterior cerebral artery”) in E-CWI (36.4%, P<0.05) and Bi-FTP in I-CWI (0%, P<0.05) was signifi?cantly higher in cerebral watershed infarctions. Conclusion FTP is probably an unique risk factor in Chinese patients with CWI.

Objective:To investigate the function of gasdermin D (GSDMD) in intestinal damage of mice with severe acute pancreatitis (SAP).Methods:The healthy C57BL/6 mice were divided into four groups randomly, including normal saline (NS) group, small interfering RNA (siRNA)-NS group, SAP model group and siRNA-SAP group, with 6 mice in each group. The SAP mouse model was reproduced by intraperitoneal injection of caerulein 50 μg/kg combined with lipopolysaccharide (LPS) 10 mg/kg; the NS group was given the same amount of NS; in the siRNA-SAP group and siRNA-NS group, siRNA 50 mg/kg was injected through the tail vein three times before modeling or injection of NS. The blood of mice eyeball in each group was taken 12 hours after modeling, and serum interleukins (IL-1β, IL-18) levels were detected by enzyme linked immunosorbent assay (ELISA). The mice were sacrificed to observe the general changes in abdominal cavity, the pancreas and ileum tissues were taken to observe the pathological changes under a light microscope. The expression of long-chain non-coding RNA uc.173 (lnc uc.173) was detected by reverse transcription-polymerase chain reaction (RT-PCR). Immunohistochemical method was used to detect the expression of tight junction proteins zonula occluden-1 (ZO-1) and Occludin in intestinal mucosal epithelial cells. Western blotting was used to detect the GSDMD protein expression level in the intestinal tissue.Results:The serum levels of IL-1β and IL-18 in the SAP model group were significantly higher than those in the NS group and the siRNA-NS group [IL-1β (ng/L): 146.66±1.40 vs. 44.48±5.76, 81.49±10.75, IL-18 (ng/L): 950.47±177.09 vs. 115.43±16.40, 84.84±21.90, all P < 0.05]; and the levels of IL-1β and IL-18 in the siRNA-SAP group were significantly lower than those in the SAP model group [IL-1β (ng/L): 116.26±15.54 vs. 146.66±1.40, IL-18 (ng/L): 689.96±126.08 vs. 950.47±177.09, both P < 0.05]. General observation showed that there were no obvious abnormalities in the abdominal cavity of the mice in the NS and siRNA-NS groups; the mice in the SAP model group and the siRNA-SAP group had different degrees of edema and congestion in the intestine; compared with the SAP model group, the abnormalities in the siRNA-SAP group was significantly reduced. Under light microscope, there were no obvious changes in the pancreas and intestinal mucosa in the NS group and the siRNA-NS group; the pancreatic tissue of the SAP model group and the siRNA-SAP group had different degrees of edema, inflammatory cell infiltration, and lobular structure damage, and the intestinal mucosa was damaged to a certain degree, and the villi were broken to varying degrees, but the damage in the siRNA-SAP group was lighter. The results of RT-PCR showed that the expression of lnc uc.173 in the intestinal tissues of the model SAP group was significantly lower than that of the NS group and the siRNA-NS group (2 -ΔΔCt: 0.26±0.12 vs. 1.01±0.37, 0.67±0.32, both P < 0.05), while the expression of lnc uc.173 in the siRNA-SAP group was significantly higher than that in the SAP model group (2 -ΔΔCt: 0.60±0.39 vs. 0.26±0.12, P < 0.05). Immunohistochemistry showed that ZO-1 and Occludin proteins in the NS group were distributed along the epithelial cells of the intestinal mucosa, showing a strong expression; ZO-1 and Occludin expressions were significantly reduced in the SAP model group and siRNA-SAP group, but the expressions in the siRNA-SAP group was higher than that in the SAP model group. Western blotting showed that the expression level of GSDMD protein in the intestinal tissues of the SAP model group was significantly higher than that of the NS group and the siRNA-NS group [GSDMD protein (GSDMD-N/β-actin): 1.99±0.46 vs. 1, 1.00±0.78, both P < 0.05]. Compared with the SAP model group, the expression of GSDMD protein in the siRNA-SAP group was significantly decreased [GSDMD protein (GSDMD-N/β-actin): 1.42±0.42 vs. 1.99±0.46, P < 0.05]. Conclusions:The systemic inflammatory response and intestinal mucosal barrier damage of SAP mice may be related to the increase of GSDMD expression in intestinal tissues. GSDMD mediates cell pyrolysis to promote the release of inflammatory factors, cause intestinal injury, and down-regulate the expression of intestinal epithelial cell tight junction proteins such as ZO-1 and Occludin, resulting in intestinal mucosal damage.

Objective To identify the mRNA sequence, genetic construction, imprinting status, and expression profile of human MURR1 gene, the homologue of mouse imprinted Murr1 gene. Methods The MURR1 mRNA sequence was identified by colony hybridization screening of human cDNA library and the 5'-RACE analyses; Absence of U2AF1-RS1 gene within MURR1 was confirmed by Southern Blotting; Expression profile of MURR1 was examined by Northern Blotting; The imprinting status of MURR1 were revealed by SNP investigation and RT-PCR followed by sequencings and RFLP analyses. Results The full-length mRNA sequence of MURR1 spans 711 bp, transcribed from 3 exons, encodes predicted MURR1 protein of 190 amino acids. The gene was expressed in all the 12 kinds of human adult tissues and 6 kinds of fetal tissues. It showed biallelic expression in all 32 investigated samples including 6 kinds of human fetal tissues and 8 adult brains. Unlike mouse imprinted U2af1-rs1 gene existing in the intron of Murr1, the human U2AF1-RS1 gene was not located in the MURR1 locus. Conclusion Human MURR1 gene is not imprinted and the non-imprinting is possible due to the absence of human homologue of mouse U2af1-rs1 within MURR1 locus.

Objective:To explore the mediating role of aging attitude and anxiety in the relationship between self-worth and depression among the elderly.Methods:From July to August 2022, a total of 536 elderly people in Shijiazhuang University for the Elderly were surveyed by the elderly self-worth scale, generalized anxiety disorder-7(GAD-7), attitudes to aging questionnaire(AAQ) and patient health questionnaire(PHQ-9). SPSS 26.0 software was used for descriptive statistics and correlation analysis.AMOS 24.0 was used to construct an intermediation model, and Bootstrap method was used for mediating effect testing.Results:(1)The score of self-worth was 101.00 (92.00, 112.00), the score of aging attitude was 92.00 (83.00, 101.75), the score of anxiety was 2.00(0, 6.00), and the score of depression was 2.00 (0, 5.00). (2)Self-worth was positively correlated with aging attitude ( r=0.67, P<0.01), while negatively correlated with anxiety ( r=-0.45, P<0.01) and depression ( r=-0.48, P<0.01). The aging attitude was negatively correlated with anxiety ( r=-0.41, P<0.01) and depression ( r=-0.41, P<0.01). Anxiety was positively correlated with depression ( r=0.71, P<0.01). (3)The indirect effect of aging attitude between self-worth and depression in the elderly was -0.016, accounting for 19.75% (-0.016/-0.081)of the total indirect effect.The indirect effect of anxiety between self-worth and depression in the elderly was -0.045, accounting for 55.56%(-0.045/-0.081) of the total indirect effect.The chain mediating effect of aging attitude and anxiety between self-worth and depression in the elderly was -0.020, accounting for 24.69%(-0.020/-0.081) of the total indirect effect. Conclusion:Aging attitude and anxiety play a chain mediating role between self-worth and depression in the elderly.

Objective:To investigate the effects of poly (ADP-ribose) polymerase-1(PARP-1) in intestinal mucosal barrier injury in rat model with severe acute pancreatitis (SAP).Methods:Twenty healthy male Wistar rats were divided into four groups ( n=5 each group) using a random table method: control, SAP, 3-aminobenzamide (3-AB), and 3-AB control groups. The SAP model was induced by intraperitoneal injection of cerulean with lipopolysaccharide. At 30 min, the rats were treated with the PARP-1 inhibitor, 3-AB, or normal saline,separately. After 12 h, all rats were sacrificed to harvest pancreas tissues, intestines tissues, and blood from the hearts for index detection. Serum amylase (AMY) and interleukin (IL)-6 levels were measured using an automatic biochemical instrument and enzyme-linked immunosorbent assay (ELISA), respectively.The protein expression of PARP-1 and nuclear factor (NF-κB) were measured using Western blot and that of occludin was measured using an immunohistochemical test. One-way analysis of variance was used for comparison of multiple groups of variables. Non-parametric tests of rank conversion were used when variances were not uniform. A P <0.05 was considered statistically significant. Results:Compared to the control group, the following indexes in the SAP group were significantly increased: ascites (with serious hemorrhage and necrosis in the pancreas and disordered intestinal villi),serum AMY and IL-6 levels, and the expression of PARP-1 and NF-κB. However, Occludin expression was significantly decreased. There was no significant difference between 3-AB group and 3-AB control group. Compared to the SAP group, the severity of SAP and pancreatitis-associated intestinal injury was significantly attenuated with the administration of 3-AB. Serum AMY and IL-6 levels were significantly decreased (serum AMY: 1 879.25 ± 736.6 U/L vs 5 569.33 ± 1993.48 U/L; IL-6: 77.98 ± 20.65 pg/mL vs 209.14 ± 79.08 pg/mL, both P<0.05), but the expression of PARP-1 and NF-κB were significantly increased (PARP-1: 1.44 ± 0.09 vs 1.49 ± 0.13; NF-κB: 0.63 ± 0.09 vs 0.96±0.08, both P<0.05). Similarly, Occludin expression was significantly decreased (6.7±1.5 vs 3.2±1.1, P<0.05). Conclusions:Inhibition of PARP-1 has protective effects on SAP associated intestinal mucosal barrier damage. The mechanism may be related to the inhibition of NF-κB signaling pathway and increase intestinal mucosal Occludin protein expression.

Objective:To explore the mediating role of boredom tendency in anxiety, depression and meaning in life in college students.Methods:Totally 590 college students in Shijiazhuang were selected to carry out a questionnaire survey, including general questionnaire, boredom proneness questionnaire (BPQ), meaning in life questionnaire (MLQ), patient health questionnaire (PHQ-9) and general anxiety disorder-7(GAD-7). Spearman correlation analysis and hierarchical regression analysis were conducted to analyze the data by using SPSS 20.0, and Amos 24.0 was used to analyze the mediating effect of boredom tendency on anxiety, depression and sense of life meaning in college students.Results:Correlation analysis found that the total score of boredom tendency was negatively correlated with meaning in life ( r=-0.260, P<0.05) and education ( r=-0.110, P<0.05). The total score of boredom tendency was positively correlated with depression ( r=0.649, P<0.05) and anxiety ( r=0.555, P<0.05). The mediating effect model fit well(χ 2/ df=0.582, GFI=1.000, AGFI=0.994, RMSEA=0.000). Boredom tendency played a partial mediating role between anxiety meaning in life(standard effect size=-0.054), a complete mediating role between depression and meaning in life(standard effect size=-0.175), and a complete mediating role between educational background and meaning in life(standard effect size=0.025). Conclusion:Boredom tendency plays a mediating role in the model between related factors and meaning in life, and attentions should be paid to the psychological development of college students.
