The number of stools in S. boulardii group was significantly less than Bifidobacterium group [MD＝－0.91， 95%CI （－1.80， －0.02）， P＝0.04]. The results of subgroup analysis showed that the duration of diarrhea in children with antibiotic-associated diarrhea in S. boulardii group was significantly shorter than Bifidobacterium group （P＜0.05）. CONCLUSIONS The efficacy and safety of S. boulardii are similar to those of Bifidobacterium in the treatment of diarrhea， but S. boulardii is better than Bifidobacterium in terms of stool number， the duration of diarrhea in children with antibiotic-associated diarrhea.

Analysis of treatment responses and kidney prognosis of atypical membranous nephropathy / 中华肾脏病杂志

Objective:To analyze the clinicopathological characteristics, treatment responses and kidney outcomes of patients with atypical membranous nephropathy (MN), and to provide information for the clinical practice.Methods:The clinical data of patients with atypical MN and synchronous primary MN who were diagnosed, treated and followed up in Peking University First Hospital from January 2008 to June 2020 were retrospectively collected and analyzed. Clinicopathological features, treatment responses and kidney prognosis were compared between the two groups. The expression of phospholipase A2 receptor (PLA2R) in kidney tissues was detected by immunofluorescence. Serum anti-PLA2R antibody was detected by enzyme-linked immunosorbent assay. Clinicopathological indexes were compared between PLA2R-related MN group and non-PLA2R-related MN group. Kaplan-Meier (Log-rank test) survival curve and multivariate Cox regression analysis methods were used to analyze the influencing factors of kidney prognosis in patients with atypical MN. The primary endpoint of renal adverse outcome was renal insufficiency, defined as end-stage renal disease or estimated glomerular filtration rate (eGFR) decline>30% baseline and<60 ml·min -1·(1.73 m 2) -1. Results:A total of 65 atypical MN patients were enrolled in this study. Compared with primary MN ( n=324), patients with atypical MN had younger age ( Z=-4.229, P<0.001), higher proportion of hematuria ( χ2=5.555, P=0.018), higher level of urinary protein ( Z=2.228, P=0.026) and lower level of eGFR ( t=-5.108, P<0.001); the proportion of IgG4 deposition in kidneys was lower ( χ2=8.081, P=0.004), and the proportions of IgA ( χ2=16.969, P<0.001) and IgM ( χ2=9.281, P=0.002) deposition were higher. There was no significant difference on gender, serum albumin, positive proportion of anti-PLA2R antibody, anti-PLA2R antibody level and kidney C3/C1q deposition between the two groups (all P>0.05). The proportions of atypical MN patients receiving renin-angiotensin aldosterone system inhibitors (49.3% vs 57.1%), calcineurin inhibitors (27.7% vs 19.1%) and cyclophosphamide (21.5% vs 23.8%) were comparable to those of primary MN patients (all P>0.05). The rates of clinical remission (80.0% vs 77.2%), partial remission (44.6% vs 44.1%), complete remission (35.4% vs 33.1%), spontaneous remission (36.9% vs 42.6%), response to cyclophosphamide (85.7% vs 81.8%), response to calcineurin inhibitor (88.9% vs 79.0%), and relapse (30.8% vs 26.8%) in atypical MN patients were comparable to those in primary MN patients (all P>0.05). During the follow-up 30.0(21.5, 61.5) months, 15 atypical MN patients (23.1%) had eGFR reduction>30%, among whom 7 patients (10.8%) had eGFR reduction>50% and 3 patients (4.6%) had end-stage kidney disease. There was no significant difference on poor kidney prognosis between the two groups (all P>0.05). Kaplan-Meier survival curve showed that patients with age>39 years old ( χ2=10.092, P=0.001), eGFR≤100 ml·min -1·(1.73 m 2) -1( χ2=5.491, P=0.019), tubular interstitial lesion ( χ2=6.999, P=0.008) and no nephropathy remission ( χ2=22.952, P<0.001) had earlier poor renal prognosis. Multivariate Cox regression analysis showed that no nephropathy remission ( HR=12.604, 95% CI 2.691-59.037, P=0.001) was an independent influencing factor for poor renal prognosis in atypical MN patients. Conclusion:No significant difference is found between atypical MN and primary MN on treatment responses and kidney prognosis, which implies that clinical practice of atypical MN can be performed by referring to the guidelines and experience of primary MN.

Correlation between serum uric acid level and symptomatic intracranial hemorrhage and outcomes in elderly patients with acute anterior circulation ischemic stroke treated with endovascular therapy / 国际脑血管病杂志

Objective:To investigate the correlation between serum uric acid level and symptomatic intracranial hemorrhage (sICH) and outcomes after endovascular therapy (EVT) in elderly patients with anterior circulation acute ischemic stroke (AIS).Methods:Elderly patients with AIS (aged ≥65 years) received EVT in Beijing Geriatric Hospital and Xuanwu Hospital from December 2017 to December 2020 were retrospectively enrolled. sICH was defined as cerebral parenchymal hemorrhage revealed by CT within 72 h after admission and the Naitonal Institutes of Health Stroke Scale score increased by ≥4 compared with the baseline. At 90 d after onset, the clinical outcome was evaluated by the modified Rankin Scale. 0-2 was a good outcome and 3-6 was a poor outcome. The clinical data of the sICH group and non-sICH group, as well as the good outcome group and poor outcome group were compared. Multivariate logistic regression analysis was used to determine the independent correlation between serum uric acid level and sICH and poor outcomes. Results:A total of 122 patients were enrolled, their age was 73.89±6.24 years, and 73 (59.8%) were male. Fifty-two patients (42.6%) had hemorrhagic transformation, 27 (22.1%) had sICH, and 28 (23.8%) had a good outcome at 90 d after onset. The serum uric acid in the sICH group was significantly lower than that in the non-sICH group ( P=0.002), while the serum uric acid in the good outcome group was similar to that in the poor outcome group ( P=0.510). Multivariate logistic analysis showed that the lower serum uric acid was an independent risk factor for sICH (odds ratio 0.994, 95% confidence interval 0.990-0.998; P=0.011). Conclusion:The lower serum uric acid level was an independent risk factor for sICH after EVT in elderly patients with AIS, but it was not associated with the outcomes.

Objective:To explore the effect of continuous quality improvement (CQI) on reducing the incidence of peritoneal dialysis (PD)-related peritonitis in patients within the first year of PD initiation.Methods:The patients who received catheter placement from January 2006 to December 2016 in our hospital were enrolled in this study. All patients were divided into four groups: pre-CQI group patients who initiated PD treatment from 2006 to 2007 (before CQI phase, group A), CQI Ⅰphrase patients who initiated PD treatment from 2008 to 2010 (group B), CQI Ⅱ phrase patients who initiated PD treatment from 2011 to 2013 (group C), and CQI Ⅲ phrase patients who initiated PD treatment from 2014 to 2016 (group D). The method of plan, do, check and act (PDCA) was conducted to decrease the incidence of PDRP. All the patients were followed up for 12 months or until they withdrew from PD in this period. Poisson analysis was used to compare the incidence of PDRP among the groups.Results:There were 2 383 PD patients recruited in this study, including 346 cases in group A, 850 cases in group B, 688 cases in group C and 499 cases in group D, with an age of (47.1±15.8) years, among whom 59.1% of the patients were male, and 21.4% with diabetes. The follow-up time was (10.9±2.8) months. Compared with group A, the incidence of PDRP was lower than that in group C (0.156 episodes/patient year vs 0.234 episodes/patient year, P=0.020); the incidence of gram positive PDRP decreased (0.052, 0.049, 0.054 episodes/patient year vs 0.104 episodes/patient year, all P<0.05) in group B, C, D; the incidence of gram negative PDRP increased in group B, then decreased in group C and group D (all P>0.05). Cox regression analysis indicated that CQI was independently associated with the incidence of gram positive PDRP ( HR=0.526, 95% CI 0.349-0.792, P=0.002). Conclusion:CQI can effectively reduce the incidence of gram positive PDRP in patients within the first year of PD initiation.

Propofol protects human cardiac AC16 cells from CoCl2-induced hypoxic injury / 中南大学学报(医学版)

To explore the effect of propofol on human cardiac AC16 cells under CoCl2-induced hypoxic injury and the possible mechanisms.
 Methods: Human AC16 cardiomyocytes were treated with cobalt chloride (CoCl2) to mimic hypoxic condition in cultured cardiomyocytes. The AC16 cells were divided into 3 groups: a control group, a CoCl2 hypoxia group (CoCl2 group), and a propofol+CoCl2 group (propofol+ CoCl2 group). The cell viability was assessed by cell counting kit-8 (CCK-8). Cell apoptosis ratio (AR) and the mitochondrial membrane potential (Δψm) were detected by flow cytometry. The reactive oxygen species (ROS) production in AC16 cells were determined with the ROS-sensitive fluorescent probe. Meanwhile, total intracellular levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in AC16 cells were detected with commercially available kits. Western blot was used to evaluate the activation of c-Jun N-terminal kinase (JNK) and p38 signaling pathways.
 Results: 1) Compared with the control group, AC16 cell viability was decreased significantly in the CoCl2 group following the treatment with 500 μmol/L CoCl2 (P<0.01); 2) Compared with the control group, AR value in AC16 cells was increased significantly in the CoCl2 group, while Δψm was decreased significantly (all P<0.01). Compared with the CoCl2 group, AR value in AC16 cells was decreased significantly in the propofol+CoCl2 group, while Δψm was increased significantly (both P<0.05); 3) Compared with the control group, the levels of ROS and MDA were increased significantly, and the level of SOD was significantly decreased in the CoCl2 group (all P<0.01). Compared with the CoCl2 group, the ROS and MDA levels in the propofol+CoCl2 group were increased significantly and the SOD levels were decreased significantly (all P<0.05); 4) Compared with the control group, the phosphorylation levels of JNK and p38 were increased significantly (both P<0.05) in the CoCl2 group. Compared with the CoCl2 group, the phosphorylation levels of JNK and p38 were decreased significantly in the propofol+CoCl2 group (both P<0.05).
 Conclusion: The pretreatment with propofol may protect human cardiac AC16 cells from the chemical hypoxia-induced injury through regulation of JNK and p38 signaling pathways.

Effect of high-dose hypofractionated radiotherapy on quality of life of patients with pancreatic cancer / 中华放射肿瘤学杂志

Objective To evaluate the effect of high-dose hypofractionated radiotherapy upon the quality of life (QOL) of patients diagnosed with pancreatic cancer. Methods In this prospective study, 50 patients with pancreatic cancer admitted to our hospital between 2016 and 2017 were recruited. All patients underwent high-dose hypofractionated helical tomotherapy. The prescription doses for PTV, CTV, and GTV were 50, 60, and 70 Gy in 15-20 fractions, 5 times per week. The QOL was evaluated by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ-C30) and pancreatic cancer-specific (European Organization for Research and Treatment of Cancer QLQ-PAN26) questionnaires before, after, 1-month and 3-month after the radiotherapy to statistically compare the QOL changes before and after radiotherapy and subsequent follow-up. Results A total of 50 patients with pancreatic cancer were included. At the end of radiotherapy, the overall QLQ-C30 score did not differ from that before radiotherapy (P＝0. 330). At 1 month after radiotherapy, the overall QLQ-C30 score was significantly higher than that before radiotherapy (P＝0. 000). The overall QLQ-C30 scores did not significantly differ at 1-and 3-month after radiotherapy ( P＝0. 665). At 3 months after radiotherapy, social function score was considerably decreased (P＝0. 047), and the remaining function scores were equal to those at 1 month post-radiotherapy. The symptoms of fatigue in the QLQ-C30 questionnaire were slightly improved at the end of radiotherapy, which were mitigated at 1-month after radiotherapy and became stable at 3-month following radiotherapy. Pain, insomnia, loss of appetite and diarrhea did not significantly change at the end of radiotherapy, whereas were improved at 1 month after radiotherapy. Nausea and vomiting were aggravated at the end of radiotherapy ( both P＝0. 000), restored to the level before radiotherapy at 1 month after radiotherapy, and the symptoms were similar at 1-and 3-month after radiotherapy. Financial difficulty was worsened at the end of radiotherapy (P＝0. 046), acceptable at 1 month after radiotherapy and worsened at 3 months following radiotherapy. In the QLQ-PAN26 questionnaire, the symptoms of pancreatic pain (backache, nocturnal pain) were mitigated at the end of radiotherapy (P＝0. 009, P＝0. 000), and further alleviated at 1 month after radiotherapy. No significant difference was noted at 1-and 3-month after radiotherapy. The body weight loss was slightly mitigated compared with that before radiotherapy ( P＝ 0. 000 ), and further improved at 1 month after radiotherapy ( P＝0. 024). No significant difference was noted at 1-and 3-month after radiotherapy ( P＝0. 226). Conclusion High-dose hypofractionated radiotherapy can significantly enhance quality of life of pancreatic cancer patients at 1- and 3- month following radiotherapy.This study further demonstrated the clinical value of high-dose hypofractionated radiotherapy in improving the quality of life on the basis of previous studies showing that high-dose hypofractionated radiotherapy can significantly improve the local control rate and survival rate of pancreatic cancer.

Clinical value of anti-liver/kidney microsomal-1 antibody in patients with liver disease / 中华肝脏病杂志

Objective@#To investigate the clinical and laboratory features of patients with liver disease and positive anti-liver/kidney microsomal-1 (anti-LKM-1) antibody, and to provide a reference for clinical diagnosis and differential diagnosis.@*Methods@#The clinical data of patients with positive anti-LKM-1 antibody who were treated in our hospital from 2006 to 2016 were collected, and clinical and laboratory features were analyzed and compared. An analysis was also performed for special cases.@*Results@#The measurement of related autoantibodies was performed for about 100 thousand case-times, and 15 patients were found to have positive anti-LKM-1 antibody. Among the 15 patients, 7 were diagnosed with type 2 autoimmune hepatitis (AIH) with an age of 11.0 ± 9.0 years and were all adolescents with acute onset; 8 were diagnosed with hepatitis C with an age of 51.5 ± 9.0 years, among whom 7 were middle-aged patients and 1 was a child aged 12 years, and all of them had an insidious onset. Compared with the patients with hepatitis C, the AIH patients had significantly higher levels of alanine aminotransferase (1 003.9 ± 904.3 U/L vs 57.0 ± 84.1 U/L, P < 0.05), aspartate aminotransferase (410.7 ± 660.3 U/L vs 34.9 ± 42.9 U/L, P < 0.05), and total bilirubin (98.0 ± 191.0 μmol/L vs 15.4 ± 6.0 μmol/L, P < 0.05). There was a reduction in immunoglobulin G after the treatment with immunosuppressant, compared with the baseline. Of all 8 patients with hepatitis C, 6 received antiviral therapy with interferon and ribavirin, and 5 out of them achieved complete response, among whom 4 had a reduction in the level of anti-LKM-1 antibody after treatment; however, a 12-year-old child developed liver failure after interferon treatment and died eventually.@*Conclusion@#Positive anti-LKM-1 antibody is commonly seen in patients with type 2 AIH or hepatitis C, but there are differences between these two groups of patients in terms of age, disease onset, liver function, and the level of anti-LKM-1 antibody. The hepatitis C patients with a confirmed diagnosis and exclusion of autoimmune hepatitis can achieve good response to interferon under close monitoring, even if anti-LKM-1 antibody is positive. As for adolescent patients with hepatitis C and positive anti-LKM-1 antibody, the possibility of AIH should be excluded.

Influence of electroacupuncture combined with personalized pleasure factor on the quality of life of patients with post-stroke depression / 中国基层医药

Objective To explore the effect of electroacupuncture combined with personalized pleasure factor on the rehabilitation of patients with poststroke depression.Methods 120 patients with poststroke depression were selected and randomly divided into two groups.60 patients in the observation group were given electroacupuncture plus individualized pleasure factor intervention,while 60 patients in the control group were given electroacupuncture only.The duration of treatment in both two groups was 3 months.The self-rating depression scale(SDS) of the two groups was compared before and after treatment.The quality of life before and after the intervention was assessed by the SF-36 health questionnaire.The limb function evaluation criteria were used to evaluate the linb motor function.The ability for living was assessed by activity of daily living scale(ADL).The cognitive function of the patients before and after the treatment was evaluated by the MMSE (Simple Mental State Examination).Results After treatment,the SDS score of the observation group was significantly lower than that of the control group (t =3.043,P =0.034).After 6 months of treatment,the overall health of the observation group was significantly better than that of the control group (t =3.236,P =0.032),the cognitive function of the observation group was significantly better than that of the control group(t =3.133,P =0.036).In the observation group,the fully independent ratio of ADL of the observation group was significantly higher than that of the control group,the difference was statistically significant (t =14.252,P =0.000).Conclusion It has great clinical significance to improve the daily living ability,limb function and cognitive function of patients with poststroke depression by electroacupuncture combined with individualized pleasure factor input,and improve the patients'depression and quality of life.

Special Review of 66 Patients Treated with Vancomycin in a Cancer Hospital / 中国药师

Objective:To evaluate the clinical application of vancomycin in a cancer hospital in order to promote the rational use of vancomycin. Methods:The records of 66 patients treated with vancomycin in 2015 were reviewed and analyzed in the respects of in-dications of medication, pathogenic examination, usage and dosage, course of treatment, drug combination, drug monitoring and drug utilization index(DUI). Results:Among the 66 cases, most drug use was rational, which accounted for 69. 70% with DUI of 0. 82. There were still several types of irrational drug use including no medication indications, irrational usage and dosage, too long or too short course of treatment, irrational combination and prophylactic use time. Conclusion:The application of vancomycin is basically ra-tional, while irrational phenomenon still exists. The management and supervision should be further strengthened in order to promote clinical rational drug use and ensure medication safety of patients.

Oncogenic miR-19a and miR-19b co-regulate tumor suppressor MTUS1 to promote cell proliferation and migration in lung cancer

MTUS1 (microtubule-associated tumor suppressor 1) has been identified that can function as a tumor suppressor gene in many malignant tumors. However, the function and mechanisms underlying the regulation of MTUS1 are unclear. In the present study, we reported that miR-19a and miR-19b (miR-19a/b) promote proliferation and migration of lung cancer cells by targeting MTUS1. First, MTUS1 was proved to function as a tumor suppressor in lung cancer and was linked to cell proliferation and migration promotion. Second, an inverse correlation between miR-19a/b expression and MTUS1 mRNA/protein expression was noted in human lung cancer tissues. Third, MTUS1 was appraised as a direct target of miR-19a/b by bioinformatics analysis. Fourth, direct MTUS1 regulation by miR-19a/b in lung cancer cells was experimentally affirmed by cell transfection assay and luciferase reporter assay. Finally, miR-19a/b were shown to cooperatively repress MTUS1 expression and synergistically regulate MTUS1 expression to promote lung cancer cell proliferation and migration. In conclusion, our findings have provided the first clues regarding the roles of miR-19a/b, which appear to function as oncomirs in lung cancer by downregulating MTUS1.
