OBJECTIVE To explore the mechanism of Huayu jiedu formula in regulating inflammatory injury in chronic kidney disease （CKD）. METHODS Fifty male SD rats were randomly divided into a sham surgery group （10 rats） and a modeling group （40 rats）. The CKD model was replicated in the modeling group by unilateral ureteral obstruction surgery. After successful modeling， the rats were randomly divided into model group， esaxerenone group （positive control）， and TCM low- and high-dose groups， with 10 rats in each group. The Esaxerenone group was given 1 mg/kg of esaxerenone， while the TCM low- and high-dose groups were given 13.7 and 27.4 g/kg of Huayu jiedu formula respectively， the sham surgery group and model group were given an equal volume of physiological saline， all groups were intervened continuously for 14 days. Hematoxylin eosin and Masson staining were used to observe the pathological changes in rat kidney tissue. Conventional biochemical methods were used to detect serum urea （SUr）， serum creatinine （SCr）， malondialdehyde （MDA）， and superoxide dismutase （SOD） levels； enzyme-linked immunosorbent assay was used to detect the levels of serum interleukin-1β （IL-1β）， IL-6， and tumor necrosis factor-α（TNF-α）； immunohistochemistry and Western blot were used to detect the protein expression of peroxisome proliferator-activated receptor γ coactivator-1α（PGC-1α） ， mitochondrial transcription factor A （TFAM）， absent in melanoma 2（AIM2）， caspase-1， gasdermin D （GSDMD）， IL-1β and IL-18 in renal tissue； real-time fluorescence quantitative PCR was used to detect the mRNA expression of AIM2. RESULTS Compared with the sham surgery group， the renal tissue of the model group showed pathological changes such as glomerular deformation and destruction， severe tubular dilation， and increased deposition of blue fibrin； the levels of SUr， SCr， MDA， IL-1β， IL-6， TNF-α，the protein expression of AIM2， GSDMD， caspase-1， IL-1β， IL-18 ， and the mRNA expression of AIM2 were significantly increased or up-regulated （P＜0.01）； the levels of SOD， the protein expression of PGC-1α， TFAM were significantly reduced or down-regulated （P＜0.01）. Compared with the model group， all treatment groups showed improvement in the above symptoms and most indicators in rats. CONCLUSIONS Huayu jiedu formula may improve renal function， alleviate renal inflammatory damage and pyroptosis， and exert renal protective effects by regulating the AIM2 pyroptosis pathway.

Critical care medicine-related treatment is an interdisciplinary and multi-professional process,often leading to secondary or concomitant mental disorders in clinical practice.Currently,there is no consensus on the pharmacological treatment of related mental illnesses in China.The Chinese Society of Psychosomatic Medicine collaborated with the Critical Care Medicine expert group to form a consensus writing expert group.After a systematic review of relevant literature,summarizing published domestic and foreign literature,and extensive discussions,the consensus was developed.The consensus elaborates on the principles and processes of the standardized use of psychotropic drugs in critical care medicine,as well as the clinical indications,precautions,and specific drug selection of various psychiatric medications,providing feasible suggestions and guidance for the clinical application of psychiatric medications in the intensive care unit.

Objective To explore the effects of Buxue Shengsui Recipe on anemia and immune injury in zebrafish and its mechanism.Methods Tg(gata1a:DsRed)zebrafish was used as experimental subjects to establish phenylhydrazine-induced zebrafish anemia model.To observe the effect of different concentrations of Buxue Shengsui Recipe on the average strength of zebrafish dorsal blood vessels.Besides,Tg(lysc:DsRed)zebrafish was used as experimental subjects to establish immune injury model of zebrafish induced by chloramphenicol and vinorelbine.To observe the effect of Buxue Shengsui Recipe on the number of neutrophils in zebrafish tail.The expression of interleukin 6(IL-6),interleukin 10(IL-10)and tumor necrosis factor α(TNF-α)mRNA was detected by Real time-PCR.Results Compared with the model group,0.5 mg·mL-1 and 2 mg·mL-1 Buxue Shengsui Recipe significantly increased the average strength of zebrafish dorsal blood vessels(P<0.01)in a dose-dependent manner.2 mg·mL-1 Buxue Shengsui Recipe significantly reversed the decrease of neutrophils caused by chloramphenicol and vinorelbine(P<0.01).Compared with the model group,the expression of IL-6 and IL-10 mRNA of zebrafish in Buxue Shengsui formula group was significantly increased(P<0.05 or P<0.01),and TNF-α mRNA expression was significantly decreased(P<0.05).Conclusion Buxue Shengsui Recipe can improve the anemia state of zebrafish induced by phenylhydrazine,and has obvious protective effect on the immune injury of zebrafish induced by chloramphenicol and vinorelbine,which is related to the up-regulation of cytokines IL-6,IL-10 and the down-regulation of TNF-α.

BACKGROUND: Although the need for consolidation chemotherapy after successful induction therapy is well established in patients with acute myeloid leukemia (AML) in first complete remission (CR1), the value of consolidation chemotherapy before allogeneic hematopoietic stem cell transplantation remains controversial. METHODS: We retrospectively compared the effect of the number of pre-transplant consolidation chemotherapies on outcomes of human leukocyte antigen-matched sibling stem cell transplantation (MSDT) for patients with AML in CR1 in multicenters across China. In our study, we analyzed data of 373 AML patients in CR1 from three centers across China. RESULTS: With a median follow-up of 969 days, patients with ≥ 3 courses of consolidation chemotherapy had higher probabilities of leukemia-free survival (LFS) (85.6% vs . 67.0%, P < 0.001) and overall survival (89.2% vs . 78.5%, P  = 0.007), and better cumulative incidences of relapse (10.5% vs . 19.6%, P  = 0.020) and non-relapse mortality (4.2% vs . 14.9%, P  = 0.001) than those with ≤ 2 courses of consolidation chemotherapy. Pre-transplantation minimal residual disease-negative patients with AML in CR1 who received MSDT with ≥ 3 courses of consolidation chemotherapy had a higher probability of LFS (85.9% vs . 67.7%, P  = 0.003) and a lower cumulative incidence of relapse (9.6% vs . 23.3%, P  = 0.013) than those with ≤ 2 courses. CONCLUSION Our results indicate that patients with AML in CR1 who received MSDT might benefit from pre-transplant consolidation chemotherapy.

Objective To investigate the clinicopathological significance of PDC in liver metastases and analyze the correlation of PDC between liver metastases and primary lesions. Methods Retrospective analysis of 72 matched cases of colorectal cancer with liver metastases was performed. The PDC in primary tumor and liver metastatic lesion was interpreted synchronously, and then the relationship between PDC in liver metastasis and clinicopathological parameters was analyzed based on the correlation of PDC between primary and metastatic lesions. In addition, PDC were interpreted in accordance with Uenos' standard. Results Among the 72 cases of liver metastasis of colorectal cancer, the number of G1, G2, and G3 graded by PDC was 28, 24, and 20, respectively. The PDC in liver metastatic lesion was correlated with tumor budding in liver metastatic lesion and PDC grade of primary lesion. No significant correlation with the size and number of liver metastatic lesion, the site, WHO grade, depth of invasion, lymph node metastasis, vascular invasion or tumor budding of the primary lesion was observed. Conclusion A positive correlation is found between liver metastasis of colorectal adenocarcinoma and PDC grade of primary tumor. Evaluating the PDC grade of primary tumor may provide a reference for the risk of liver metastasis.

Objective:To study the optimal timing of laparoscopic cholecystectomy (LC) after percutaneous transhepatic gallbladder drainage (PTGBD) for grade Ⅱ-Ⅲ acute cholecystitis.Methods:A multicenter, single blind and randomized controlled study was conducted at Shanghai Fifth People's Hospital Affiliated to Fudan University, Shanghai Pudong Hospital, and Shanghai Minhang District Central Hospital from October 2018 to September 2021. Patients who underwent LC after PTGBD were divided 1∶1 into the early group and the late group. LC was performed 4-6 weeks after PTGBD in the early group and 7-8 weeks after PTGBD in the late group. Gender, age, AC grade, complications after PTGBD, body mass index, complications before LC, operation time of LC, intraoperative bleeding, total treatment cost, conversion rate to open surgery and complications after LC were compared between the two groups. The 36-Item Short Form Health Survey (SF-36) before and after LC was also compared.Results:Of 248 patients who were eligible for the study, there were 52 males and 196 females, with ages ranging from 18 to 89 years, and mean ±s.d. of (52.5 ± 20.2) years. There were 126 patients in the early group and 122 patients in the late group. There were no significant differences in gender, age, AC grade, body mass index and complications before LC between the two groups (all P>0.05). The preoperative score of SF-36 in the early group was significantly better than that in late group, and the complications of PTGBD in the late group were significantly higher than the early group (both P<0.05). The operation time and total treatment cost of the early group were significantly less than those of the late group (37.2±12.8 min vs. 48.5±19.7 min, 20 856±2 136 yuan vs. 2 2207±2 049 yuan) (both P<0.05). The intraoperative bleeding volume of LC in the early group was [ M( Q1, Q3)] 40 (40, 60) ml and the late group was [ M( Q1, Q3)] 35 (25, 40) ml. The difference was also significant ( P<0.05). There was no significant differences in the conversion rates to open surgery, complications and SF-36 scores after LC between the two groups (all P>0.05). Conclusion:LC should be performed 4-6 weeks after PTGBD for grade Ⅱ-Ⅲ acute cholecystitis. Although the amount of intraoperative bleeding was higher, the operation time was shorter, the burden on patients was reduced and there was more rapid recovery.

Objective:To explore the efficacy of a flat ground exoskeleton robot in improving the walking ability of stroke survivors.Methods:Fifty-eight stroke survivors with mobility difficulties were randomly divided into a robot group ( n=29) and a control group ( n=29). In addition to routine rehabilitation, the control group received conventional walking training, while the robot group underwent exoskeleton robot-assisted gait training. The 30-minute training sessions were held twice a day, 5 days per week for 5 weeks. Before as well as after 2 and 4 weeks of treatment, everyone′s walking ability was tested using the 6-minute walk test (6MWT) and functional ambulation scale (FAC). General lower limb motor function was quantified using the Fugl-Meyer Lower Extremity assessment (FMA-LE). Moreover, gait analysis was conducted before and after 4 weeks of treatment. Results:After 2 and 4 weeks of treatment, the average 6MWT times of both groups were significantly better than before the treatment, with the improvement of the robot group significantly greater than that of the control group after 2 weeks. After 2 and 4 weeks the average FMA-LE and FAC scores of both groups had improved significantly compared with before treatment. After 4 weeks the stride frequency and gait cycle of both groups had improved significantly.Conclusions:Exoskeleton robot-assisted gait training can improve walking ability and lower limb motor function of stroke survivors about as well as conventional walking training.

Metabolic regulation has been proven to play a critical role in T cell antitumor immunity. However, cholesterol metabolism as a key component of this regulation remains largely unexplored. Herein, we found that the low-density lipoprotein receptor (LDLR), which has been previously identified as a transporter for cholesterol, plays a pivotal role in regulating CD8
