BACKGROUND: Whether high cut-off (HCO) membranes are more effective than high-flux (HF) membranes in patients requiring renal replacement therapy (RRT) remains controversial. The aim of this systematic review was to investigate the efficacy of HCO membranes regarding the clearance of inflammation-related mediators, β2-microglobulin and urea; albumin loss; and all-cause mortality in patients requiring RRT. METHODS: We searched all relevant studies on PubMed, Embase, Web of Science, the Cochrane Library, and China National Knowledge Infrastructure, with no language or publication year restrictions. Two reviewers independently selected studies and extracted data using a prespecified extraction instrument. Only randomized controlled trials (RCTs) were included. Summary estimates of standardized mean differences (SMDs) or weighted mean differences (WMDs) and risk ratios (RRs) were obtained by fixed-effects or random-effects models. Sensitivity analyses and subgroup analyses were performed to determine the source of heterogeneity. RESULTS: Nineteen RCTs involving 710 participants were included in this systematic review. Compared with HF membranes, HCO membranes were more effective in reducing the plasma level of interleukin-6 (IL-6) (SMD -0.25, 95% confidence interval (CI) -0.48 to -0.01, P   =  0.04, I2  = 63.8%); however, no difference was observed in the clearance of tumor necrosis factor-α (TNF-α) (SMD 0.03, 95% CI -0.27 to 0.33, P  = 0.84, I2  = 4.3%), IL-10 (SMD 0.22, 95% CI -0.12 to 0.55, P  = 0.21, I2  = 0.0%), or urea (WMD -0.27, 95% CI -2.77 to 2.23, P  = 0.83, I2  = 19.6%). In addition, a more significant reduction ratio of β 2 -microglobulin (WMD 14.8, 95% CI 3.78 to 25.82, P  = 0.01, I2  = 88.3%) and a more obvious loss of albumin (WMD -0.25, 95% CI -0.35 to -0.16, P  < 0.01, I2  = 40.8%) could be observed with the treatment of HCO membranes. For all-cause mortality, there was no difference between the two groups (risk ratio [RR] 1.10, 95% CI 0.87 to 1.40, P  = 0.43, I2  = 0.0%). CONCLUSIONS Compared with HF membranes, HCO membranes might have additional benefits on the clearance of IL-6 and β 2-microglobulin but not on TNF-α, IL-10, and urea. Albumin loss is more serious with the treatment of HCO membranes. There was no difference in all-cause mortality between HCO and HF membranes. Further larger high-quality RCTs are needed to strengthen the effects of HCO membranes.

Poria is an important medicine for inducing diuresis to drain dampness from the middle energizer. However, the specific effective components and the potential mechanism of Poria remain largely unknown. To identify the effective components and the mechanism of Poria water extract (PWE) to treat dampness stagnancy due to spleen deficiency syndrome (DSSD), a rat model of DSSD was established through weight-loaded forced swimming, intragastric ice-water stimulation, humid living environment, and alternate-day fasting for 21 days. After 14 days of treatment with PWE, the results indicated that PWE increased fecal moisture percentage, urine output, D-xylose level and weight; amylase, albumin, and total protein levels; and the swimming time of rats with DSSD to different extents. Eleven highly related components were screened out using the spectrum-effect relationship and LC-MS. Mechanistic studies revealed that PWE significantly increased the expression of serum motilin (MTL), gastrin (GAS), ADCY5/6, p-PKAα/β/γ cat, and phosphorylated cAMP-response element binding protein in the stomach, and AQP3 expression in the colon. Moreover, it decreased the levels of serum ADH, the expression of AQP3 and AQP4 in the stomach, AQP1 and AQP3 in the duodenum, and AQP4 in the colon. PWE induced diuresis to drain dampness in rats with DSSD. Eleven main effective components were identified in PWE. They exerted therapeutic effect by regulating the AC-cAMP-AQP signaling pathway in the stomach, MTL and GAS levels in the serum, AQP1 and AQP3 expression in the duodenum, and AQP3 and AQP4 expression in the colon.

OBJECTIVE: To evaluate the clinical value of Dachengqi decoction in the treatment of sepsis complication with gastrointestinal dysfunction via gastric antrum cross-sectional area (CSA) measured by bedside ultrasound. METHODS: A parallel group randomized controlled trial was conducted. A total of 80 patients with sepsis with gastrointestinal dysfunction admitted to the Second Affiliated Hospital of Nanjing University of Chinese Medicine from January 2021 to October 2022 were enrolled. According to whether patients agree to use Dachengqi decoction after admission, all patients were divided into Dachengqi decoction group (observation group) and conventional treatment group (control group) by 1 : 1 randomization, each group has 40 patients. Both groups were treated with fluid resuscitation, anti-infection, maintaining stable respiratory circulation, early nourishing feeding, promoting gastrointestinal motility, and regulating intestinal flora. The observation group was treated with Dachengqi decoction on the basis of western medicine, 30 mL decoction was taken in the morning and evening. Both groups were treated for 7 days. The CSA of the two groups was measured by bedside ultrasound before and after treatment. The gastric residual volume (GRV1 and GRV2) were calculated by formula and traditional gastric tube withdrawal method. The gastrointestinal dysfunction score, acute physiology and chronic health evaluation II (APACHE II), intraperitoneal pressure (IAP), serum preprotein (PA), albumin (Alb), white blood cell count (WBC), procalcitonin (PCT), hypersensitivity C-reactive protein (hs-CRP), length of intensive care unit (ICU) stay and incidence of aspiration were detected to evaluate the clinical efficacy of Dachengqi decoction, the correlation and advantages and disadvantages between CSA measured by bedside ultrasound and other evaluation indicators of gastrointestinal dysfunction in sepsis were also analyzed. RESULTS: There were no significant differences in the indicators before treatment between the two groups, which were comparable. In comparison with the pre-treatment period, CSA, GRV, gastrointestinal dysfunction score, APACHE II score, IAP, WBC, PCT, and hs-CRP of the two groups after treatment were significantly decreased, PA and Alb were significantly increased, and the observation group decreased or increased more significantly than the control group [CSA (cm²): 4.53±1.56 vs. 6.04±2.52, GRV1 (mL): 39.85±8.21 vs. 53.05±11.73, GRV2 (mL): 29.22±5.20 vs. 40.91±8.97, gastrointestinal dysfunction score: 0.87±0.19 vs. 1.35±0.26, APACHE II score: 11.54±3.43 vs. 14.28±3.07, IAP (cmH₂O, 1 cmH₂O ≈ 0.098 kPa): 9.79±2.01 vs. 13.30±2.73, WBC (×10⁹/L): 9.35±1.24 vs. 12.35±1.36, PCT (μg/L): 3.68±1.12 vs. 6.43±1.45, hs-CRP (mg/L): 24.76±5.41 vs. 46.76±6.38, PA (mg/L): 370.29±45.89 vs. 258.33±34.58, Alb (g/L): 38.83±5.64 vs. 33.20±4.98, all P < 0.05]. The length of ICU stay (days: 10.56±3.19 vs. 14.24±3.45) and incidence of aspiration (12.5% vs. 25.0%) were lower than those in the control group (both P < 0.05). Correlation analysis showed that CSA measured by bedside ultrasound was positively correlated with GRV2, gastrointestinal dysfunction score, APACHE II score, and IAP (r values were 0.84, 0.78, 0.75, 0.72, all P < 0.01) and negatively correlated with PA and Alb (r values were -0.64 and -0.62, both P < 0.01). CONCLUSIONS The Dachengqi decoction can significantly improve the clinical symptoms of septic patients with gastrointestinal dysfunction, reduce systemic inflammatory response, improve nutritional status, and shorten ICU hospital stay. Bedside ultrasound monitoring of CSA is a simple, accurate and effective means to evaluate gastrointestinal dysfunction, which is worthy of further clinical promotion.

OBJECTIVE: To investigate the value of pre-treatment albumin/fibrinogen ratio (AFR) on the prognosis of patients with diffuse large B-cell lymphoma (DLBCL). METHODS: The data of DLBCL patients in the Affiliated Hospital of North Sichuan Medical College from April 2014 to March 2021 were retrieved, and 111 newly diagnosed patients who completed at least 4 cycles of R-CHOP or R-CHOP-like chemotherapy with complete data were included in the study. The clinical, laboratory examination and follow-up data of the patients were collected, and the receiver operating characteristic curve (ROC) was drawn according to patients' AFR before treatment and the survival status at the end of the follow-up, which could be used to preliminarily evaluate the predictive value of AFR for disease progression and patients' survival outcome. Furthermore, the correlation of AFR with the clinical and laboratory characteristics, progression-free survival (PFS) and overall survival (OS) was analyzed, and finally, univariate and multivariate Cox proportional hazard regression models were used to analyze factors affecting PFS and OS of DLBCL patients. RESULTS: The ROC curve indicated that AFR level had a moderate predictive value for PFS and OS in DLBCL patients, with the area under the curve (AUC) of 0.616 (P =0.039) and 0.666 (P =0.004), respectively, and the optimal cut-off values were both 9.06 for PFS and OS. Compared with high-AFR (≥9.06) group, the low-AFR (<9.06) group had a higher proportion of patients with Lugano III-IV stage ( P <0.001), elevated lactate dehydrogenase (P =0.007) and B symptoms (P =0.038). The interim analysis of response showed that the overall response rate (ORR) in the high-AFR group was 89.7%, which was significantly higher than 62.8% in the low-AFR group (P =0.001). With a median follow-up of 18.5 (3-77) months, the median PFS of the high-AFR group was not reached, which was significantly superior to 17 months of the low-AFR group (P =0.009). Similarly, the median OS of high-AFR group was not reached, either, which was significantly superior to 48 months of the low-AFR group (P < 0.001). In multivariate Cox regression analysis, AFR <9.06 was an independent risk factor both for PFS and OS (HR _PFS=2.047, P =0.039; HR _OS=4.854, P =0.001). CONCLUSION Pre-treatment AFR has a significant value for the prognosis evaluation in newly diagnosed DLBCL patients.

OBJECTIVE: To explore the clinical characteristics of hospitalized patients with hematologic diseases complicated with carbapenem-resistant organisms (CRO) infection and analyze the risk factors of 30-day all-cause mortality. METHODS: The clinical data and laboratory test data of 77 hospitalized patients with hematologic diseases complicated with CRO infection in department of hematology of the Third Hospital of Shanxi Medical University from January 2015 to December 2020 were retrospectively analysed, the risk factors of 30-day all-cause mortality after CRO infection were analyzed by multivariate logistic regression. RESULTS: Among the total of 77 patients with hematologic diseases complicated with CRO infection, 29 died and 48 survived within 30 days of infection, with a case fatality rate of 37.66%. A total of 93 strains of CRO were isolated from these patients, of which Acinetobacter baumannii had the highest detection rate (25.81%, 24/93), followed by Pseudomonas aeruginosa (18.28%, 17/93). The lung was the most common site of CRO infection. The detected pathogens were highly resistant to carbapenems, and 64.52% (60/93) of the pathogens were resistant to imipenem with minimum inhibitory concentration (MIC)≥16 μg/ml. The results of the univariate analysis showed that albumin concentration <25 g/L (P =0.048), serum creatinine concentration≥120 μmol/L (P =0.023), age-adjusted Charlson comorbidity index (ACCI) (P =0.037) and primary treatments (supportive treatment, immunosuppressive therapy, chemotherapy, HSCT) (P =0.048) were significantly associated with 30-day all-cause mortality after infection. The results of multivariate logistic regression analysis showed that when CRO infection confirmed, albumin concentration <25 g/L (P =0.014, OR=6.171), serum creatinine concentration≥120 μmol/L (P =0.009, OR=10.867) were independent risk factors for 30-day mortality of patients with hematologic diseases complicated with CRO infection. CONCLUSION The mortality rate of CRO-infected patients with hematologic diseases is high. The detected pathogenic bacteria are highly resistant to imipenem. The albumin concentration <25 g/L and the serum creatinine concentration≥ 120 μmol/L at diagnosis of CRO infection were independent risk factors for 30-day mortality of the patients with hematologic diseases.

OBJECTIVE: To explore the high-risk clinical factors of early death in patients with secondary hemophagocytic lymphohistiocytosis (sHLH), and further identify the clinical factors related to the rapid progression of sHLH in the short term. METHODS: The clinical manifestations, laboratory examination and prognosis of sHLH patients were retrospectively analyzed. Continuous variables were grouped by median, univariate and multivariate Cox regression analysis and Kaplan-Meier survival curve were used to explore the risk factors affecting early death of sHLH. Then, a nomogram model was established with independent risk factors, Bootstrap resampling method was used for verification, and consistency index (C-index) and calibration curve were used to detect the prediction accuracy. RESULTS: A total of 126 sHLH patients were enrolled, with a median age of 48.5(16-88) years, including 74 males and 52 females. Fifty-five patients (43.6%) died within 30 days, including 39 males and 16 females. Univariate regression analysis showed that lymphocyte count <0.45×10⁹/L, platelet count (PLT) <39.5×10⁹/L, prothrombin time (PT)≥13.3 s, activated partial thromboplastin time (APTT)≥39.7 s, albumin (ALB) <25.9 g/L, lactate dehydrogenase (LDH)≥811 U/L, creatinine (Cr) ≥67 μmol/L and procalcitonin (PCT)≥0.61 ng/ml were risk factors for death within 30 days in sHLH patients. Multivariate regression analysis showed that lymphocyte count <0.45×10⁹/L, APTT≥39.7 s and ALB <25.9 g/L were independent risk factors for death within 30 days in sHLH patients. A nomogram model was established based on the above three risk factors, its C-index was 0.683, and the calibration chart showed good agreement between the observed and predicted values of sHLH. CONCLUSIONS Lymphopenia, prolonged APTT, and hypoalbuminemia are risk factors for early death of sHLH patients. Early identification and positive intervention are expected to reduce early mortality in sHLH patients. The nomogram model based on the above risk factors provides a method for clinicians to evaluate sHLH.

Objective: To examine the clinical efficacy of 3 anti-reflux methods of digestive tract reconstruction after proximal gastrectomy for gastric cancer. Methods: The clinical data and follow-up data of gastric cancer patients who underwent anti-reflux reconstruction after proximal gastrectomy in 11 medical centers of China from September 2016 to August 2021 were retrospectively collected, including 273 males and 65 females, aging of (63±10) years (range: 28 to 91 years). Among them, 159 cases were performed with gastric tube anastomosis (GTA), 107 cases with double tract reconstruction (DTR), and 72 cases with double-flap technique (DFT), respectively. The duration of operation, length of postoperative hospital stay and early postoperative complications (referring to Clavien-Dindo classification) of different anti-reflux reconstruction methods were assessed. Body mass index, hemoglobin and albumin were used to reflect postoperative nutritional status. Reflux esophagitis was graded according to Los Angeles criteria based on the routinely gastroscopy within 12 months after surgery. The postoperative quality of life (QoL) was evaluated by Visick score system. The ANOVA analysis, Kruskal-Wallis rank sum test, χ² test and Fisher's exact test were used for comparison between multiple groups, and further comparison among groups were performed with LSD, Tamhane's test or Bonferroni corrected χ² test. The mixed effect model was used to compare the trends of Body mass index, hemoglobin and albumin over time among different groups. Results: The operation time of DFT was significantly longer than that of GTA and DTR ((352±63) minutes vs. (221±66) minutes, (352±63) minutes vs. (234±61) minutes, both P<0.01). The incidence of early complications with Clavien-Dindo grade Ⅱ to Ⅴ in GTA, DFT and DTR groups was 17.0% (27/159), 9.7% (7/72) and 10.3% (11/107), respectively, without significant difference among these three groups (χ²=3.51, P=0.173). Body mass index decreased more significantly in GTA than DFT group at 6 and 12 months after surgery (mean difference=1.721 kg/m², P<0.01; mean difference=2.429 kg/m², P<0.01). body mass index decreased significantly in DTR compared with DFT at 12 months after surgery (mean difference=1.319 kg/m², P=0.027). There was no significant difference in hemoglobin or albumin fluctuation between different reconstruction methods perioperative. The incidence of reflux esophagitis one year after surgery in DTR group was 12.9% (4/31), which was lower than that in DFT (45.9% (17/37), χ²=8.63, P=0.003). Follow-up of postoperative quality of life showed the incidence of Visick grade 2 to 4 in DFT group was lower than that in GTA group (10.4% (7/67) vs. 34.6% (27/78), χ²=11.70, P=0.018), while there was no significant difference between DFT and DTR group (10.4% (7/67) vs. 22.2% (8/36, P>0.05). Conclusions: Compared with GTA and DTR, DFT is more time-consuming, but there is no significant difference in early complications among three methods. DFT reconstruction is more conducive to maintain postoperative nutritional status and improve QoL, especially compared with GTA. The risk of reflux esophagitis after DTR reconstruction is lower than that of DFT.

Objective: To investigate the effects and mechanism of diammonium glycyrrhizinate (DG) on liver injury in severely scalded rats. Methods: The experimental research method was used. Fifty-four female Sprague-Dawley rats aged 7-9 weeks were divided into sham injury group with simulated injury on the back, and simple scald group and scald+DG group with scald of 30% total body surface area on the back, with 18 rats in each group. Rats in sham injury group were not specially treated after injury, and rats in simple scald group and scald+DG group were rehydrated for antishock. Besides, rats in scald+DG group were injected intraperitoneally with 50 mg/kg DG at post injury hour (PIH) 1, 25, and 49. Rats in the three groups were collected, the serum content of liver function injury related indexes including aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), total protein, and albumin was measured by automatic biochemical assay analyzer, and serum content of ornithine carbamoyl transferase (OCT) was measured by enzyme-linked immunosorbent assay method at PIH 24, 48, and 72; hepatic histopathological changes at PIH 72 were observed by hematoxylin-eosin staining; the mRNA expressions of B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), glucose regulated protein 78 (GRP78), activating transcription factor 4 (ATF4), and protein kinase R-like endoplasmic reticulum kinase (PERK) in liver tissue were detected by real-time fluorescent quantitative reverse transcription polymerase chain reaction at PIH 24, 48, and 72. The protein expressions of Bcl-2, Bax, GRP78, PERK, and ATF4 in liver tissue were detected by Western blotting at PIH 72 in sham injury group and PIH 24, 48, and 72 in simple scald group and scald+DG group. The number of samples was 6 in each group at each time point. Data were statistically analyzed with analysis of variance for factorial design, one-way analysis of variance, and Bonferroni test. Results: Compared with that in sham injury group, the serum content of AST, ALT, and LDH was significantly increased (P<0.01), and the serum content of total protein and albumin was significantly decreased (P<0.05 or P<0.01) of rats in simple scald group at all post-injury time points. Compared with those in simple scald group, the serum AST content of rats in scald+DG group at PIH 24 was decreased significantly (P<0.05); the serum AST, ALT, and LDH content of rats in scald+DG group at PIH 48 was decreased significantly (P<0.01), and the serum total protein content was increased significantly (P<0.01); the serum AST, ALT, and LDH content of rats in scald+DG group at PIH 72 was decreased significantly (P<0.01), and the serum total protein and albumin content was increased significantly (P<0.01). At PIH 24, 48, and 72, the serum OCT content of rats in simple scald group was (48.5±3.9), (40.8±2.4), and (38.7±2.0) U/L, which was significantly higher than (15.1±2.5), (15.7±2.6), and (16.4±3.7) U/L in sham injury group (P<0.01), and (39.0±4.5), (31.8±2.0), and (22.1±2.6) U/L in scald+DG group (P<0.05 or P<0.01). At PIH 72, the cells in liver tissue of rats in sham injury group had normal morphology and regular arrangement, with no obvious inflammatory cell infiltration; the cells in liver tissue of rats in simple scald group had disordered arrangement, diffuse steatosis, and moderate inflammatory cell infiltration; the cells in liver tissue of rats in scald+DG group arranged regularly, with scattered steatosis and a small amount of inflammatory cell infiltration. Compared with those in sham injury group, the Bcl-2 mRNA (P<0.05 or P<0.01) and protein expressions of liver tissue were significantly decreased, and the mRNA (P<0.01) and protein expressions of Bax were significantly increased in rats in simple scald group at PIH 24, 48, and 72. Compared with those in simple scald group, the mRNA (P<0.05) and protein expressions of Bax in liver tissue of rats in scald+DG group were decreased significantly at PIH 48; the mRNA (P<0.01) and protein expressions of Bax in liver tissue of rats in scald+DG group were significantly decreased, and the mRNA (P<0.01) and protein expressions of Bcl-2 were significantly increased at PIH 72. Compared with those in sham injury group, the mRNA (P<0.05 or P<0.01) and protein expressions of ATF4, GRP78, and PERK in liver tissue were significantly increased in rats in simple scald group at all post-injury time points. Compared with those in simple scald group, the mRNA (P<0.01) and protein expressions of ATF4 in liver tissue of rats in scald+DG group at PIH 48 were significantly decreased, and the mRNA (P<0.05 or P<0.01) and protein expressions of ATF4, GRP78, and PERK were significantly decreased in liver tissue of rats in scald+DG group at PIH 72. Conclusions: DG can effectively reduce the degree of liver injury in rats after severe scald, and the mechanism may involve alleviating endoplasmic reticulum stress and mitigating mitochondrial damage.

OBJECTIVE: To analyze the change of serum C1q in the course of multiple myeloma (MM) and its correlation with clinical characteristics. METHODS: A total of 138 newly diagnosed MM patients in Zhongnan Hospital of Wuhan University from June 2016 to December 2019 were selected as research objects, during the same period 50 age-matched anemia patients, 50 lymphoma patients, 50 leukemia patients, and 50 myelodysplastic syndrome (MDS) patients were selected as control groups. All the patients met WHO disease classification, and were definitely diagnosed by pathology or bone marrow smear/biopsy. The changes of C1q between MM patients and control group, as well as in different therapeutic responses of MM patients before and after treatment were compared, also the difference of clinical characteristics among MM patients with different C1q level, so as to analyze risk factors which led to C1q decline. RESULTS: The average value of C1q in MM patients was (128.18±51.24) mg/L, which was significantly lower than control group (P<0.01). The levels of white blood cell, platelet (PLT), hemoglobin (Hb), serum calcium, albumin, lactate dehydrogenase (LDH) in newly diagnosed high C1q group were significantly higher than those in low C1q group (P<0.05). Logistic analysis showed that the levels of PLT, Hb, albumin, and LDH in newly diagnosed high C1q group were higher than those in low C1q group (r=0.248, r=0.394, r=0.405, r=0.295). After treatment, the levels of C1q in MM patients with complete remission and very good partial remission were significantly higher than before treatment (P<0.05), while those with partial remission and stable disease also increased but not significantly (P>0.05). CONCLUSION The C1q level in MM patients is significantly lower than that in patients with other hematologic system diseases, and it increases with the remission of the disease after treatment.
