Clinical outcomes of serial endoscopic balloon dilation for duodenal Crohn's disease-associated strictures.

BACKGROUND: Endoscopic balloon dilation (EBD) is a safe and effective treatment for Crohn's disease (CD)-associated strictures. However, serial EBDs have rarely been reported. This study aimed to evaluate the efficacy and safety of serial EBDs for treating CD-associated duodenal strictures compared with intermittent EBDs. METHODS: Patients with CD-associated duodenal strictures who underwent EBD were recruited. The clinical data, stricture characteristics, number of EBDs, dilation diameter, complications, surgical interventions, and follow-up periods were recorded. Patients were divided into a serial dilation group and an intermittent dilation group to analyze the differences in safety and efficacy. RESULTS: Forty-five patients with duodenal CD-associated strictures underwent a total of 139 dilations. A total of 23 patients in the serial dilation group underwent 72 dilations, for a median of 3 (range 3 ~ 4) dilations per patient, and 22 patients in the intermittent dilation group underwent 67 dilations, for a median of 3 (range 1 ~ 6) dilations per patient. Technical success was achieved in 97.84% (136/139) of the patients. During the follow-up period, three patients in the intermittent dilation group underwent surgery, and the total clinical efficacy was 93.33% (42/45). No difference in safety or short-term efficacy was noted between the two groups, but serial EBDs exhibited significantly greater clinical efficacy between 6 months and 2 years. No significant difference in recurrence-free survival was observed, but the median longest recurrence-free survival and recurrence-free survival after the last EBD in the serial dilation group were 693 days (range 298 ~ 1381) and 815 days (range 502 ~ 1235), respectively, which were significantly longer than the 415 days (range 35 ~ 1493) and 291 days (range 34 ~ 1493) in the intermittent dilation group (p = 0.013 and p = 0.000, respectively). At the last follow-up, the mean diameter of the duodenal lumen was 1.17 ± 0.07 cm in the serial dilation group, which was greater than the 1.11 ± 0.10 cm in the intermittent dilation group (p = 0.018). We also found that the Simple Endoscopic Score for Crohn's Disease was associated with an increased risk of surgical intervention (HR 2.377, 95% CI 1.125-5.020; p = 0.023) and recurrence at 6 months after the last EBD (HR 0.698, 95% CI 0.511-0.953; p = 0.024), as assessed by univariate analysis. CONCLUSIONS: Compared to the intermittent EBDs, serial EBDs for duodenal CD-associated strictures exhibit greater clinical efficacy within two years and could delay stricture recurrence. We suggest that serial EBDs can be a novel option for endoscopic treatment of duodenal CD-associated strictures.

The highly effective cadmium-resistant mechanism of Pseudomonas aeruginosa and the function of pyoverdine induced by cadmium.

Pyoverdine (PVD) plays an important role in reducing cadmium (Cd) accumulation in plants. Some Pseudomonas aeruginosa (P. aeruginosa) species can produce PVD under Cd(Π) stress. However, the function of Cd(Π)-induced PVD remains unclear. In this study, we isolated a highly effective Cd(Π)-resistant P. aeruginosa which can secrete PVD under Cd(Π) stress and found that PVD secretion has a dose-dependent relationship with Cd(Π) concentration. PVD can form a PVD-Cd complex with Cd(Π), though the PVD-Cd complex is unable to be adsorbed by the cell or enter the cell, so the complexation of PVD and Cd(Π) impedes Cd(Π) adsorption on the cell surface and alleviates the oxidative stress, lipid peroxidation, and morphological destruction of the cell caused by Cd(Π) and effectively improves the resistance of P. aeruginosa to Cd(Π). In summary, our research results indicate that the Cd(Π) resistance mechanism of P. aeruginosa screened is the complexation of PVD for Cd(Π) and the adsorption of bacteria for Cd(Π); furthermore, PVD plays an important role in improving the Cd(Π)-resistant ability of bacteria. This study provides a deeper understanding of the highly effective Cd(Π) resistance mechanism of P. aeruginosa and the function of Cd(Π)-induced PVD in bacteria.

The effect of the whole-process care model of the medical union on the improvement of kinesiophobia and bone mineral density in patients with osteoporosis.

OBJECTIVE: To observe the effect of the whole-process care model of the medical union on the improvement of kinesiophobia and bone mineral density in patients with osteoporosis. METHODS: In this descriptive study, a convenient sampling method was used to select 148 patients with osteoporosis who visited the hospital from January 2020 to December 2021. Patients aged ≥ 18 years and diagnosed with osteoporosis through quantitative computed tomography (QCT) were included in the study. They were able to cooperate during follow-up and had normal cognitive function. Patients with combined spinal curvature, thoracic deformity, and pulmonary dysfunction, accompanied by severe cardiovascular or limb dysfunction, and those who withdrew midway or participated in other clinical studies were excluded. According to whether to use the whole-process care model of the medical union, they were divided into intervention group and control group, with 74 cases each. The control group used conventional care, and the intervention group used the whole-process care model of the medical association. The occurrence of kinesiophobia between the two groups were compared. The dual-energy X-ray absorption detector is used to measure differences in bone density changes. RESULTS: There was no significant difference between the two groups in the TSK scale score and the incidence of kinesiophobia before intervention (P > 0.05). The TSK scale scores of patients in the intervention group were higher than those in the control group at 3 months and 6 months after operation (P < 0.05). The incidence of kinesiophobia in the intervention group for 3 months and 6 months was significantly lower than that in the control group (P < 0.05). There was no significant difference in bone mineral density between the two groups before and 3 months after intervention (P > 0.05). The bone mineral density of lumbar spine, femoral neck and total hip in the intervention group was significantly higher than that in the control group after 6 months of intervention (P < 0.05). CONCLUSION: The whole-process care model of the medical association is used for osteoporosis patients, which might reduce the risk of kinesiophobia and improve the bone density of the lumbar spine and total hip in patients. But further promotion and improvement of relevant support systems are needed to achieve comprehensive promotion and maximize clinical benefits in this field.

Cellular senescence contributes to mechanical ventilation-induced diaphragm dysfunction by upregulating p53 signalling pathways.

BACKGROUND: Mechanical ventilation can cause acute atrophy and injury in the diaphragm, which are related to adverse clinical results. However, the underlying mechanisms of ventilation-induced diaphragm dysfunction (VIDD) have not been well elucidated. The current study aimed to explore the role of cellular senescence in VIDD. METHODS: A total of twelve New Zealand rabbits were randomly divided into 2 groups: (1) spontaneously breathing anaesthetized animals (the CON group) and (2) mechanically ventilated animals (for 48 h) in V-ACV mode (the MV group). Respiratory parameters were collected during ventilation. Diaphragm were collected for further analyses. RESULTS: Compared to those in the CON group, the percentage and density of sarcomere disruption in the MV group were much higher (p < 0.001, both). The mRNA expression of MAFbx and MuRF1 was upregulated in the MV group (p = 0.003 and p = 0.006, respectively). Compared to that in the CON group, the expression of MAFbx and MuRF1 detected by western blotting was also upregulated (p = 0.02 and p = 0.03, respectively). Moreover, RNA-seq showed that genes associated with senescence were remarkably enriched in the MV group. The mRNA expression of related genes was further verified by q-PCR (Pai1: p = 0.009; MMP9: p = 0.008). Transverse cross-sections of diaphragm myofibrils in the MV group showed more intensive positive staining of SA-ßGal than those in the CON group. p53-p21 axis signalling was elevated in the MV group. The mRNA expression of p53 and p21 was significantly upregulated (p = 0.02 and p = 0.05, respectively). The western blot results also showed upregulation of p53 and p21 protein expression (p = 0.03 and p = 0.05, respectively). Moreover, the p21-positive staining in immunofluorescence and immunohistochemistry in the MV group was much more intense than that in the CON group (p < 0.001, both). CONCLUSIONS: In a rabbit model, we demonstrated that mechanical ventilation in A/C mode for 48 h can still significantly induce ultrastructural damage and atrophy of the diaphragm. Moreover, p53-dependent senescence might play a role in mechanical ventilation-induced dysfunction. These findings might provide novel therapeutic targets for VIDD.

Protective Restraint Nursing Interventions in ICU Patients: Assessing their Influence on Unplanned Extubation and Skin Injury Incidence.

Objective: This study aims to investigate the application of protective restraint nursing interventions in intensive care unit (ICU) patients and their impact on the incidence of unplanned extubation and skin damage. Methods: A total of 90 ICU patients admitted to Hai'an People's Hospital between January 2019 and December 2020 were randomly assigned to either the experimental group or the control group in a 1:1 ratio. The control group received conventional nursing care, while the experimental group received protective restraint nursing interventions. The Hospital Anxiety and Depression (HAD) scale, a clinical tool used to assess patients' levels of anxiety and depression, was employed to evaluate patients' emotional states before and after the intervention. A Patient Clinical Satisfaction Survey Questionnaire developed by our department was used to assess patient satisfaction after nursing. Compliance and the incidence of adverse reactions were compared between the two groups. Results: The experimental group exhibited significantly lower HADS scores, higher nursing satisfaction, and a lower incidence of unplanned extubation, skin damage, and adverse reactions compared to the control group (all P < .05). Conclusions: Protective restraint care demonstrates substantial benefits for ICU patients by reducing the incidence of unplanned extubation, preventing skin damage during treatment, improving compliance, and facilitating recovery. These findings support the clinical application and promotion of protective restraint nursing interventions.

SETDB1 induces lenalidomide resistance in multiple myeloma cells via epithelial­mesenchymal transition and PI3K/AKT pathway activation.

SET domain bifurcated histone lysine methyltransferase 1 (SETDB1) is a histone H3K9 methyltransferase that stimulates cell proliferation by methylating AKT, which contributes to drug resistance in multiple myeloma (MM). Lenalidomide is an immunomodulatory agent widely used in the treatment of MM. However, lenalidomide resistance occurs in patients with MM. Currently, the role of SETDB1 in lenalidomide resistance in MM remains unclear. Thus, the present study aimed to explore the functional association between SETDB1 and lenalidomide resistance in MM. The analysis of GEO datasets revealed that SETDB1 was upregulated in lenalidomide-resistant MM cells and that its expression was associated with poor prognosis of patients with MM. Apoptosis analysis revealed that overexpression of SETDB1 in MM cells significantly decreased apoptosis, while knockdown of SETDB1 increased apoptosis. Furthermore, the IC50 value of lenalidomide in MM cells increased following SETDB1 overexpression and decreased following SETDB1 silencing. Additionally, SETDB1 mediated epithelial-mesenchymal transition (EMT) and activated the PI3K/AKT pathway. Mechanistic analysis revealed that inhibition of PI3K/AKT signaling in MM cells increased apoptosis, sensitized the cells to lenalidomide and inhibited EMT, whereas SETDB1 overexpression inhibited the effects of PI3K/AKT cascade inhibition. In conclusion, the findings of the present study indicated that SETDB1 promoted lenalidomide resistance in MM cells by promoting EMT and the PI3K/AKT signaling pathway. Thus, SETDB1 may be a potential therapeutic target for MM.

Proliferation Inhibitory Activity of Quinones from Blaps rynchopetera Defense Secretion on Colorectal Tumor Cells.

OBJECTIVE: To explore the proliferation inhibitory effect of quinones from Blaps rynchopetera defense secretion on colorectal tumor cell lines. METHODS: Human colorectal cancer cell HT-29, human colorectal adenocarcinoma cell Caco-2 and normal human colon epithelial cell CCD841 were chosen for the evaluation of inhibitory activity of the main quinones of B. rynchopetera defense secretion, including methyl p-benzoquinone (MBQ), ethyl p-benzoquinone (EBQ), and methyl hydroquinone (MHQ), through methyl thiazolyl tetrazolium assay. The tumor-related factors, cell cycles, related gene expressions and protein levels were detected by enzyme-linked immunosorbent assy, flow cytometry, RT-polymerase chain reaction and Western blot, respectively. RESULTS: MBQ, EBQ, and MHQ could significantly inhibit the proliferation of Caco-2, with half maximal inhibitory concentration (IC50) values of 7.04 ± 0.88, 10.92 ± 0.32, 9.35 ± 0.83, HT-29, with IC50 values of 14.90 ± 2.71, 20.50 ± 6.37, 13.90 ± 1.30, and CCD841, with IC50 values of 11.40 ± 0.68, 7.02 ± 0.44 and 7.83 ± 0.05 µg/mL, respectively. Tested quinones can reduce the expression of tumor-related factors tumor necrosis factor α, interleukin (IL)-10, and IL-6 in HT-29 cells, selectively promote apoptosis, and regulate the cell cycle which can reduce the proportion of cells in the G1 phase and increase the proportion of the S phase. Meanwhile, tested quinones could up-regulate mRNA and protein expression of GSK-3ß and APC, while down-regulate that of ß-catenin, Frizzled1, c-Myc, and CyclinD1 in the Wnt/ß-catenin pathway of HT-29 cells. CONCLUSION: Quinones from B. rynchopetera defense secretion could inhibit the proliferation of colorectal tumor cells and reduce the expression of related factors, which would be functioned by regulating cell cycle, selectively promoting apoptosis, and affecting Wnt/ß-catenin pathway-related mRNA and protein expressions.

PEEP application during mechanical ventilation contributes to fibrosis in the diaphragm.

BACKGROUND: Positive end-expiratory airway pressure (PEEP) is a potent component of management for patients receiving mechanical ventilation (MV). However, PEEP may cause the development of diaphragm remodeling, making it difficult for patients to be weaned from MV. The current study aimed to explore the role of PEEP in VIDD. METHODS: Eighteen adult male New Zealand rabbits were divided into three groups at random: nonventilated animals (the CON group), animals with volume-assist/control mode without/ with PEEP 8 cmH2O (the MV group/ the MV + PEEP group) for 48 h with mechanical ventilation. Ventilator parameters and diaphragm were collected during the experiment for further analysis. RESULTS: There was no difference among the three groups in arterial blood gas and the diaphragmatic excursion during the experiment. The tidal volume, respiratory rate and minute ventilation were similar in MV + PEEP group and MV group. Airway peak pressure in MV + PEEP group was significantly higher than that in MV group (p < 0.001), and mechanical power was significantly higher (p < 0.001). RNA-seq showed that genes associated with fibrosis were enriched in the MV + PEEP group. This results were further confirmed on mRNA expression. As shown by Masson's trichrome staining, there was more collagen fiber in the MV + PEEP group than that in the MV group (p = 0.001). Sirius red staining showed more positive staining of total collagen fibers and type I/III fibers in the MV + PEEP group (p = 0.001; p = 0.001). The western blot results also showed upregulation of collagen types 1A1, III, 6A1 and 6A2 in the MV + PEEP group compared to the MV group (p < 0.001, all). Moreover, the positive immunofluorescence of COL III in the MV + PEEP group was more intense (p = 0.003). Furthermore, the expression of TGF-ß1, one of the most potent fibrogenic factors, was upregulated at both the mRNA and protein levels in the MV + PEEP group (mRNA: p = 0.03; protein: p = 0.04). CONCLUSIONS: We demonstrated that PEEP application for 48 h in mechanically ventilated rabbits will cause collagen deposition and fibrosis in the diaphragm. Moreover, activation of the TGF-ß1 signaling pathway and myofibroblast differentiation may be the potential mechanism of this diaphragmatic fibrosis. These findings might provide novel therapeutic targets for PEEP application-induced diaphragm dysfunction.

Clinical Promotion of Comfort Nursing Combined with Comprehensive Nursing in the Treatment of Severe Stroke Patients with Diabetes in ICU.

Objective: To investigate the application value of comprehensive nursing combined with comfort nursing for severe stroke patients with diabetes in the intensive care unit (ICU), as well as its effect on the incidence of pressure ulcers and aspiration. Methods: Between March 2019 and March 2021, 123 severe stroke patients with diabetes who were treated at our hospital were randomly assigned to one of two groups: the control group (n = 61) or the study group (n = 62). The control group received normal care, but the research group received comprehensive nursing as well as comfort nursing. The two patient groups were compared in terms of the effects of the clinical application. Results: The two groups did not differ significantly in general data (P > 0.05). The shorter ICU monitoring and extubation times, the lower incidence of pressure ulcers, aspiration, and nosocomial infections, and higher self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores and a lower MOS 36-item short-form health survey (SF-36) score were all observed in the research group when compared to the control group (P < 0.05). Conclusion: For severe stroke patients with diabetes in the ICU, comprehensive nursing combined with comfort nursing has a promising effect, significantly, lowering the risk of pressure ulcers, aspiration, and nosocomial infections, accelerating physical recovery, enhancing mental state, and ensuring a better prognosis, deserving general clinical promotion.

A ratiometric nanoprobe for the in vivo bioimaging of hypochlorous acid to detect drug-damaged liver and kidneys.

As the organs responsible for toxin transformation and excretion in the body, damage to the liver and kidneys induced by inevitable drug toxicity is the main cause of acute liver and kidney injury. P-Acetamidophenol overdose leads hypochlorous acid (HClO) to accumulate in the mitochondria of tissues, ultimately resulting in acute liver and kidney injury in humans, despite its clinical use as an antipyretic medicine. Herein, we report an HClO-activatable self-assembling ratiometric nanoprobe NRH-800-PEG for screening the upregulation of HClO by colocalization in mitochondria while monitoring the changes in the endogenous HClO levels in cells with ratiometric signals. Furthermore, NRH-800-PEG was constructed to evaluate injury by fluorescence ratio imaging in the tissues of inflammatory mice. Our strategy offers a novel tool for assessing disease progression during drug-induced liver and kidney injury.

Efficacy and safety of tolvaptan versus placebo in the treatment of patients with autosomal dominant polycystic kidney disease: a meta-analysis.

OBJECTIVE: The objective of this meta-analysis was to compare the efficacy and drug safety of tolvaptan with placebo for autosomal dominant polycystic kidney disease (ADPKD). METHODS: The PubMed, Embase, and Cochrane Library databases were searched from inception to September 10, 2021. Eligible studies comparing tolvaptan and placebo in the treatment of patients with ADPKD were included. Data were analysed using Review Manager Version 5.3. RESULTS: Thirteen studies involving 3575 patients were included in the meta-analysis. Compared with placebo, tolvaptan had a better effect on delaying eGFR decline (MD 1.27, 95% CI 1.24-1.29, P < 0.01) and TKV increase (MD - 3.01, 95% CI - 3.55 to - 2.47, P < 0.01) in ADPKD treatment. Additionally, tolvaptan reduced the incidence of complications such as renal pain (OR 0.71, 95% CI 0.58-0.87, P < 0.01), urinary tract infection (OR 0.69, 95% CI 0.54-0.89, P < 0.01), haematuria (OR 0.68, 95% CI 0.51-0.89, P < 0.01), and hypertension (OR 0.66, 95% CI 0.52-0.82, P < 0.01). However, tolvaptan was associated with a higher incidence rate of adverse events such as thirst (OR 8.48 95% CI 4.53-15.87, P < 0.01), polyuria (OR 4.71, 95% CI 2.17-10.24, P < 0.01), and hepatic injury (OR 4.56, 95% CI 2.51-8.29, P < 0.01). CONCLUSION: Tolvaptan can delay eGFR decline and TKV increase and reduce complications such as renal pain, urinary tract infection, haematuria, and hypertension in the treatment of ADPKD. However, tolvaptan increases the adverse effects of thirst, polyuria and hepatic injury.

Single-balloon Enteroscopy for Evaluation of Small Bowel Crohn Disease Strictures: Peripheral Blood Lymphocytes As a Risk Factor for Strictures.

BACKGROUND: Few reports have focused on single-balloon enteroscopy (SBE) for evaluation of small bowel Crohn disease (CD) strictures. The aim of this study was to analyze the relationships between peripheral blood inflammatory markers and small bowel CD strictures observed by SBE. MATERIALS AND METHODS: CD patients who underwent SBE between January 2016 and December 2020 were enrolled. The clinical characteristics and peripheral blood inflammatory markers were collected and analyzed to screen for predictive factors significantly associated with small bowel CD strictures. RESULTS: A total of 221 CD patients underwent SBE. The lymphocyte (LC) counts in peripheral blood were significantly lower in the active group (n=178) than in the inactive group (n=43) according to the simple endoscopic score for CD (SES-CD), P =0.011, and was correlated with the SES-CD ( r =-0.134, P =0.047). The LC levels were significantly lower in the stricture group (n=116) than in the nonstricture group (n=105) based on whether small bowel strictures developed, P =0.000, and LC was a risk factor for strictures in the multivariate analysis [hazard ratio (HR), 2.332; 95% CI, 1.102-4.937; P =0.027]. In the subgroup analysis, LC levels notably decreased after stricture aggravation ( P =0.000). Forty-seven patients who underwent small bowel resection underwent SBE at 6 to 12 months after surgery. The LC level was significantly lower in the postoperative patients with strictures ( P =0.025), and LC (HR, 4.444; 95% CI, 1.265-15.617; P =0.020) was a risk of postoperative strictures by univariate analysis, but the age at diagnosis (HR, 6.462; 95% CI, 1.272-22.560; P =0.022) was an independent risk factor by multivariate analysis. CONCLUSION: Peripheral blood LC levels were correlated with SES-CD and gradually decreased as the intestinal stricture increased in small bowel CD patients. The LC level was also significantly lower in the postoperative CD patients with strictures. The level of LC was a risk factor for small bowel strictures. These results suggest that peripheral blood LC could be a novel marker of small bowel CD strictures to guide CD diagnosis and therapy.

Analysis of Placement Priorities and Nursing Countermeasures of Transnasally Inserted Intestinal Obstruction Catheters in Patients with Acute Small Bowel Obstruction.

Objective: To explore the placement priorities and analysis of nursing countermeasures of transnasally inserted intestinal obstruction catheters in patients with acute small bowel obstruction (ASBO). Methods: One hundred and three patients with ASBO treated in our hospital from May 2016 to February 2022 were enrolled to this study. Patients who received individual nursing for transnasally inserted intestinal obstruction catheters were considered as the observation group (n = 59) and those who received traditional nursing were regarded as the control group (n = 44). The symptom relief time, daily gastrointestinal decompression, bowel sound recovery time, exhaust, defecation recovery time, and gas-liquid plane disappearance time were compared between both groups. The abdominal pain was evaluated by visual analogue scale (VAS), and the psychology of patients was evaluated by self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Patients' clinical efficacy and incidence of adverse effects were counted, and quality of life was assessed using the short form 36 (SF-36) health survey questionnaire. Results: In the observation group, the improvement time of clinical symptoms and VAS, SAS, and SDS scores after intubation were lower than those of the control group, while the total clinical treatment efficiency was higher (P < 0.05). As to the adverse effects, the observation group was lower than the control group (P < 0.05). Also, the SF-36 scores were higher than those of the control group in all dimensions (P < 0.05). Conclusion: The individual nursing strategy implemented for the transnasally inserted intestinal obstruction catheter can effectively shorten the recovery of ASBO patients and improve their treatment outcome and prognosis quality of life.

Mitochondria-Targeted Ratiometric Chemdosimeter to Detect Hypochlorite Acid for Monitoring the Drug-Damaged Liver and Kidney.

Liver and kidney injury caused by drug toxicity is a serious threat to human health. Acetaminophenol (APAP), as a common antipyretic and analgesic drug, inevitably causes injury. When it is overused, hypochlorous acid (HClO) is excessively generated due to metabolic abnormalities, resulting in the accumulation of HClO in the mitochondria of liver and kidney tissues and causing damage. In this study, we designed a series of HClO responsive ratiometric chemdosimeter NRH-X (NRH-O, NRH-S, and NRH-C) to evaluate liver and kidney injury, and found that NRH-O has a specific sensitive response to HClO. NRH-O can not only monitor the variations of endogenous HClO content of living cells by fluorescence ratio changes in the mitochondria but also detect the upregulation of HClO induced by APAP. In addition, NRH-O can also be used for anatomic diagnosis of liver and kidney injury by fluorescence ratio imaging of HClO in the tissues of inflammatory mice.

High-Quality Nursing Combined with the Whole-Course Responsibility Nursing Intervention Reduces the Incidence of Complications in Severe Aneurysmal Subarachnoid Hemorrhage.

Objective: The aim of this study is to study the influence of whole-course responsibility nursing combined with high-quality nursing intervention on the level of life and complications of severe aneurysmal subarachnoid hemorrhage patients with postoperative coma. Methods: From December 2018 to December 2020, 90 severe aneurysmal subarachnoid hemorrhage patients with postoperative coma were selected and were divided into two groups, the experimental group and the control group, with 45 cases in each group. The control group adopted conventional nursing care, and the experimental group received whole-course responsibility nursing combined with high-quality nursing intervention. The nursing effect, degree of coma, coma recovery, and incidence of complications between all groups were compared. Results: Compared with the control group, the experimental group yielded more favorable achievement in terms of the nursing effect (P < 0.05). Superior levels of the Glasgow Coma Scale (GCS) score, Coma Recovery Scale-Revised (CRS-R) score, GQOLI-74 score, and BI score of the experimental group were obtained and compared with the control group (all P < 0.05). The experimental group witnessed a lower complication rate, as compared to the other group (P < 0.05). Conclusion: The whole-course responsibility nursing combined with high-quality nursing intervention is applied to severe aneurysmal subarachnoid hemorrhage patients with postoperative coma, which can substantially optimize the nursing efficiency, improve the degree of coma, help recover consciousness, ameliorate the mental state and the quality of life, and reduce the incidence of complications, which is worthy of clinical application.

Immunomodulatory effects of Blaps rynchopetera extract.

PURPOSE: To explore the potential immunomodulatory effects of total extract and different polar parts from Blaps rynchopetera Fairmaire. METHODS: Phagocytic activity was evaluated by neutral red assay, and the effect of the immune function was investigated by normal and immunocompromised mice models. RESULTS: In vitro, total extract, as well as chloroform, ethyl acetate, n-butanol and water fractions could individually enhance the phagocytic ability of mouse peritoneal macrophages; in addition, chloroform and ethyl acetate fractions had an increasing tendency when combined stimulation with lipopolysaccharide (LPS). In vivo, ethyl acetate fraction (EAF) could enhance the immune organ index, increase the serum hemolysin level and peripheral blood immune cells of immunocompromised mice, while for normal mice, the effect was inconspicuous. CONCLUSIONS: Blaps rynchopetera extracts had noteworthy immunomodulatory effect, especially for individuals with immune disorders.

Efficacy and safety of tacrolimus versus corticosteroid as initial monotherapy in adult-onset minimal change disease: a meta-analysis.

OBJECTIVE: The objective of this meta-analysis was to compare the efficacy and safety of tacrolimus (TAC) monotherapy versus corticosteroid as initial monotherapy in adult-onset minimal change disease (MCD) patients. METHODS: Databases including PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, and Wanfang database were searched from the inception to March 20, 2021. Eligible studies comparing TAC monotherapy and corticosteroid as initial monotherapy for adult-onset MCD patients were included. Data were analyzed using Review Manager Version 5.3. RESULTS: Four randomized controlled trials (RCTs) involving 196 patients were included in the meta-analysis. For initial monotherapy for adult-onset MCD, TAC and corticosteroid had similar complete remission (OR 1.06, 95% CI 0.47-2.41, P = 0.89), total remission (OR 1.30, 95% CI 0.39-4.35, P = 0.67), relapse rate (OR 0.63, 95% CI 0.28-1.42, P = 0.26). Main drug-related adverse effects of two therapeutic regimens had no difference concerning infection (OR 0.54, 95% CI 0.23-1.27, P = 0.15), glucose intolerance (OR 0.55, 95% CI 0.16-1.84, P = 0.33) and acute renal failure (OR 1.37, 95% CI 0.36-7.31, P = 0.71). CONCLUSION: TAC monotherapy is comparable with corticosteroid monotherapy in initial therapy of MCD. To further confirm the conclusion, more large multicenter RCTs are necessary.

Efficacy and safety of over-the-scope clips (OTSC®) for closure of gastrointestinal fistulas less than 2 cm.

BACKGROUND AND AIM: Gastrointestinal (GI) fistula is a complication of surgery associated with potential morbidity and mortality. The aim of this study was to evaluate the efficacy and safety of over-the-scope clips (OTSC®) for closing GI fistulas. METHODS: Patients with GI fistula who underwent endoscopic closure using OTSC® were enrolled. The clinical date, duration, location and diameter of the fistula, technical success of the OTSC®, complications, follow-up periods and clinical success were recorded. RESULTS: A total of 98 patients with GI fistula underwent OTSC® closure. Their median age was 50 years (range 16-88 years), and the median duration of the fistula was 185.5 days (range 12-3129 days). The mean diameter of fistula was 4.64 ± 1.16 mm. Technical success was achieved in 100% of the patients, and clinical success was achieved in 55.10% (54/98) of the patients after a median follow-up of 168.5 days (range 36-424 days). Based on the location of the fistula, the clinical success rate of treating a fistula in the esophagus and small intestine was 100%, followed by the rectum (70%, 7/10), anastomotic stoma (61.90%, 13/21), duodenum (53.33%, 8/15), colon (47.06%, 8/17), stomach (43.47%, 10/23) and appendix stump (33.33%, 2/6). The duration of the fistula (HR 3.609, 95% CI 1.387-9.387, P = 0.009) was a risk factor for clinical success by multivariate analysis. CONCLUSION: OTSC® is a safe and efficient treatment for GI fistula and is a potential alternative to the surgical approach. Before OTSC® placement, the duration of the fistula should be assessed since it is related to the successful closures with OTSC®.
