In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

Objective    To evaluate the survival results of surgical resection (SR) and CT-guided percutaneous ablation (PA) for stageⅠnon-small cell lung cancer (NSCLC). Methods    The PubMed, Web of Science, EMbase, The Cochrane Library, CNKI, VIP, Wanfang databases from inception to June 2021 were searched to collect comparative studies on the survival results between SR and CT-guided PA treatment for stageⅠNSCLC. RevMan 5.3 software was used for statistical analysis of data. Results    A total of 3 114 patients were included in 11 studies. The results of meta-analysis showed that compared with the PA group, the SR group had a higher 2-year postoperative overall survival (OS) rate (OR=1.44, 95%CI 1.00-2.06, P=0.05), 3-year postoperative OS rate (OR=2.37, 95%CI 1.47-3.81, P<0.001), 5-year OS rate (OR=1.64, 95%CI 1.19-2.28, P<0.01), 5-year progression-free survival rate after operation (OR=2.43, 95%CI 1.54-3.82, P<0.001) and lower local recurrence rate (OR=0.26, 95%CI 0.13-0.54, P<0.001). There were no statistical differences between the two groups in terms of 1-year postoperative OS rate, 1-year, 2-year, and 3-year tumor-related survival rates, 1-year, 2-year tumor-free survival rates, or distant postoperative recurrence rate (P>0.05). Conclusion    For patients with stageⅠNSCLC with optimal basic conditions, surgery is a more appropriate treatment. For patients who cannot withstand surgical injuries or refuse surgery, CT-guided PA is also a potential alternative treatment. However, this conclusion needs  to be verified by prospective controlled trials with larger sample sizes and a more rigorous design.

Objective To develop a simplified phantom for the calibration of whole-body counters. Methods A simplified phantom design method for the calibration of whole-body counters was established based on the process and method of calibrating whole-body counters. By using the established method and Monte Carlo method, a simplified phantom including the total body, thyroid, lungs, and gastrointestinal tract was designed to calibrate the ORTEC-Stand FAST II whole-body counter. The simplified phantom was compared with the BOMAB phantom through experimental measurements. Results Within the range of 50 keV to 2 MeV, for rays of the same energy in the same organ of the simplified phantom and BOMAB phantom, the simulated data of detection efficiency by whole-body counting showed an error within 5%, and the experimental measurements showed an error within 10%. Conclusion We developed a simplified phantom for the calibration of the whole-body counter, demonstrating the feasibility of using the simplified phantom instead of a physical body phantom for whole-body counter calibration, which can greatly facilitate whole-body counter calibration for internal radiation monitoring.

Objective:To observe the expression of microRNA (miRNA)-7159-5p in gastric cancer tissues, and explore its effect on the proliferation and invasion of gastric cancer cells and its molecular mechanism.Methods:The cancer tissues and adjacent tissues of 29 patients with gastric cancer who underwent surgical resection in Hubei 672 Orthopedic Hospital of Integrated Traditional Chinese and Western Medicine from March 2018 to November 2019 were collected. Fluorescence real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-7159-5p in gastric cancer tissues and adjacent tissues, gastric cancer cell lines and normal gastric epithelial cell lines. Select the cell line with the lowest expression of miR-7159-5p, set the control group and the experimental group, and be transfected with control and miR-7159-5p mimics respectively. qRT-PCR was used to detect the expression of miR-7159-5p in transfected cells. The lymphocyte proliferation test (MTS method) was used to detect the proliferation of transfected cells, and the Transwell chamber method was used to detect the invasion activity of transfected cells. The miRNAMap database and dual luciferase reporter gene experiment were used to predict and verify the target genes of miR-7159-5p. qRT-PCR and Western blot were used to detect the expression of target genes in transfected cells.Results:The expression of miR-7159-5p in gastric cancer tissues was lower than that in adjacent tissues ( P<0.01), the expression of miR-7159-5p in gastric cancer cell lines was lower than that of normal gastric epithelial cells (all P<0.01), and the expression of miR-7159-5p was the lowest in SGC7901 cells ( P<0.01). After transfection, the expression of miR-7159-5p in SGC7901 cells of the experimental group was significantly higher than that in the control group ( P<0.01). After transfection, the proliferation activity and the cell invasion activity of the experimental group was significantly lower than that of the control group (all P<0.01). The target gene of miR-7159-5p was tripartite motif 26 (TRIM26). After transfection, the expression of TRIM26 mRNA in SGC7901 cells of the experimental group was significantly lower than that in the control group ( P<0.01). Western blot showed that after transfection, the expression of TRIM26, c-Myc, cyclin D1, β-catenin protein were lower than those in the control group (all P<0.05). Conclusions:The expression of miR-7159-5p is low in gastric cancer tissues, and miR-7159-5p can inhibit the proliferation and invasion of SGC7901 cells by down-regulating the expression of TRIM26.

BACKGROUND: This study retrospectively analyzed the application value of lung cancer immunotherapy prognostic index (LIPI) and iSEND immune scoring system in advanced non-small cell lung cancer (NSCLC) patients treated with immunotherapy in China, in order to find guidance for clinical development of NSCLC treatment plan. METHODS: The clinical data of 178 patients with advanced NSCLC treated with immunotherapy were analyzed retrospectively. LIPI and iSEND immune scores were performed, receiver operating characteristic (ROC) curves were drawn, and the predictive values of two models for objective response rate (ORR), disease control rate (DCR), and progression-free survival (PFS) were compared. Kaplan-Meier method was used for survival analysis, and Cox regression analysis method was used for univariate analysis and multivariate analysis. RESULTS: The area under the curver (AUC) of ORR, DCR and PFS predicted by iSEND immune score were 0.616, 0.634 and 0.631 respectively; LIPI were 0.789, 0.750 and 0.732 respectively, which were higher than iSEND immune score (P<0.05). The median PFS of patients in LIPI score groups 0, 1 and 2 were 9.9 months, 6.1 mon and 3.7 mon respectively; The median PFS of patients with good, moderate and poor iSEND immune scores were 9.9 mon, 7.0 mon and 3.5 mon respectively, with statistically significant differences (P<0.001). In the immunotherapy subgroup, the median PFS of patients with different LIPI and iSEND immune scores was also statistically significant. Cox regression analysis showed that the derived neutrophil to lymphocyte ratio (dNLR), lactic dehydrogenase (LDH) and PFS were independently correlated (P<0.05). CONCLUSIONS LIPI and iSEND immune scoring system can effectively predict the efficacy and prognosis of advanced NSCLC treated with immunotherapy, and LIPI has higher predictive value than iSEND immune scoring system.

Objective:To investigate the application value of right minimal invasive three-port technique of laparoscopic sleeve gastrectomy (RMIT-LSG) for the treatment of obesity.Methods:The retrospective and descriptive study was conducted. The clinical data of 66 obesity patients who underwent RMIT-LSG in the Sir Run Run Shaw Hospital of Zhejiang University School of Medicine from January to October 2021 were collected. There were 15 males and 51 females, aged 28.5(range, 16.0?54.0)years. The body mass index (BMI) of the 66 patients was (36.9±4.3)kg/m 2. There were 20 of the 66 patients combined with type 2 diabetes. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination or the WeChat to detect postoperative recovery of patients including body mass changing, BMI and complications 6 months after operation. The follow-up was up to December 2021. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations. All the 66 patients underwent RMIT-LSG successfully, without conversion to laparotomy or changing surgical method. The operation time and the volume of intraoperative blood loss of the 66 patients were (132±22)minutes and (14±8)mL, respectively. (2) Postoperative situations. The time to postoperative initial out-of-bed activities, time to postoperative first flatus, time to postoperative initial water intake, time to postoperative initial liquid food intake and duration of postoperative hospital stay of the 66 patients were (15±6)hours, (1.80±0.60)days, (1.00±0.20)days, (2.00±0.20)days and (3.40±0.60)days, respectively. Of the 66 patients, one case underwent post-operative abdominal hemorrhage at postoperative day 1 and received a second surgery for hemostasis. The patient with postoperative abdominal hemorrhage and other 65 patients recovered well without gastroparesis, gastric fistula, abdominal infection and other complication. (3) Follow-up. All the 66 patients were followed up for 6(range, 1?11)months. All the 66 patients completed the postoperative scar photography at postoperative 1 month, and results of scar photography showed concealed scar with good cosmetic effects. Twenty-seven of the 66 patients were followed up for 6 months after operation, with the weight loss, percentage of weight loss and decrease of BMI were (42±7)kg, 34.8%±2.9%, (14.2±1.9)kg/m 2, respectively. None of the 66 patient had innutrition during the follow-up. Conclusion:The RMIT-LSG is safe and feasible for the treatment of obesity, with a good cosmetic effect of the wound.

Objective:To investigate the correlation of blood pressure variability within 24 h after thrombolysis with symptomatic intracerebral hemorrhage (sICH) and 90 d outcome in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke treated with recombinant tissue plasminogen activator in the Department of Neurology, Jinshan Branch, Shanghai Sixth People's Hospital from January 2017 to May 2019 were enrolled prospectively. The baseline data of the patients were collected. The patients were divided into sICH group and non-sICH group according to the changes of head CT and the National Institutes of Health Stroke Scale (NIHSS) score after thrombolysis. At 90 d after thrombolysis, the modified Rankin scale was used to evaluate the outcomes, and the patients were divided into a good outcome group (0-2) and a poor outcome group (3-6). The blood pressure within 24 h after thrombolysis was monitored and the parameters related to blood pressure variability in 5 time periods (0-2 h, 2-6 h, 6-12 h, 12-18 h, and 18-24 h) were calculated, including systolic blood pressure (SBP) and diastolic blood pressure (DBP) maximum (max), minimum (min), maximum and minimum difference (max-min) and mean (mean). The differences between the adjacent blood pressures were calculated, the standard deviation (SD), successive variation (SV), rise successive variability (SVrise), drop successive variability (SVdrop), the maximum squared difference in blood pressure rise (SVrisemax), the maximum squared difference in blood pressure drop (SVdropmax) were calculated and recorded, respectively. Multivariate logistic regression analysis was used to evaluate the effect of various blood pressure variability parameters on sICH and the outcomes after intravenous thrombolysis. Results:A total of 112 patients receiving intravenous thrombolysis were included in the study. Their median age was 71 years (range, 38-92 years), 66 were males (58.9%); median baseline NIHSS score was 10. Seventeen patients (15.2%) developed hemorrhagic transformation, 10 of them (8.9%) were sICH. The 90-d follow-up showed that 73 patients (65.2%) had a good outcome, 39 (34.8%) had a poor outcome and 7 of them (6.3%) died. There were significant differences in hypertension ( P=0.029), ischemic heart disease ( P=0.012), total cholesterol ( P=0.033), baseline NIHSS score ( P=0.003) between the sICH group and the non-sICH group. There were significant differences in age ( P=0.025), gender ( P=0.005), atrial fibrillation ( P=0.003), etiologic classification of stroke ( P=0.003), baseline NIHSS score ( P<0.001) and sICH ( P=0.003) between the poor outcome group and the good outcome group. In addition, there were significant differences in multiple blood pressure variability parameters among the above groups (all P<0.05). Multivariate logistic regression analysis showed that DBP SVdropmax, 6-12 h DBP SV, 12-18 h DBP SV, 6-12 h DBP SVdrop, 12-18 h DBP SVdrop were the independent risk factors for sICH after intravenous thrombolysis (all P<0.05); 2-6 h SBP SV, 2-6 h SBP SVrise, 2-6 h SBP SVdrop, 2-6 h DBP SV, 2-6 h DBP SVrise and 2-6 h DBP SVdrop were the independent risk factors for poor outcome after intravenous thrombolysis (all P<0.05). Conclusions:Early blood pressure and some blood pressure variability parameters are closely related to sICH and outcomes after intravenous thrombolysis in acute ischemic stroke. Closely monitoring of blood pressure and its variability can help clinical management and outcome prediction after intravenous thrombolysis.
