OBJECTIVE To explore the effect and mechanism of Zexie tang （ZXT） on reducing lipid accumulation through network pharmacology， and compare the difference of traditional decoction versus formula granules. METHODS The active components and targets of ZXT were identified using TCMSP and SwissTargetPrediction databases. GeneCards， OMIM， DisGeNET and TTD databases were used to analyze the related targets of non-alcoholic fatty liver disease （NAFLD）； protein-protein interaction network model was constructed by String database；“ ZXT-NAFLD target-pathway” network diagram was constructed by using CytoScape software； target enrichment analysis was performed by using Metascape platform. Fat accumulation model of human hepatocellular carcinoma HepG2 cells was established to observe the effects of traditional decoction and formula granules of ZXT on lipid accumulation of cells. RESULTS Alisol B， alisol C， 1-monolinolein and alisol B monoacetate were the key active components of ZXT in the treatment of NAFLD. The core targets included MDM2， MAPK1， PIK3CB， PRKCQ and MAPK14， etc. The core signaling pathways included endocrine resistance， insulin resistance and Th17 cell differentiation. Compared with model group， except for the Zexie formula granules group and Baizhu formula granules group， the absorbance values in all other administration groups were significantly decreased （P＜0.01）； the absorbance value of Baizhu traditional decoction group was significantly higher than that of ZXT traditional decoction group （P＜0.01）； the absorbance values of Zexie formula granule group and Baizhu formula granule group were significantly higher than that of ZXT formula granule group （P＜0.01）； the absorbance value of Zexie formula granule group was significantly higher than that of Zexie traditional decoction group （P＜0.01）； the absorbance value of Baizhu formula granule group was significantly higher than that of Baizhu traditional decoction group （P＜0.01）. CONCLUSIONS ZXT reduces lipid accumulation of human hepatocellular carcinoma cells through multiple components， multiple target and multiple pathways， and its traditional decoction and formula granules exhibit slightly different lipid-lowering effects.

ObjectiveBy analyzing the current situation of drug selection and evaluation in medical institutions in the world，we aim to understand the development of relevant selection methods and tools，provide reference basis for drug selection in traditional Chinese medicine （TCM） medical institutions，and promote the optimization of drug catalogs in TCM medical institutions. MethodBased on the method of scoping review，the eight databases were systematically searched，the included documents were screened，extracted and analyzed，and the research results were graphically displayed. ResultA total of 23 articles were included in this study，including 13 in Chinese and 10 in English，involving 23 methods or tools related to drug selection. Of the 14 methods or tools from Chinese medical institutions，the earliest one was published in 2012，and five were published in 2022. The published methods or tools involved different levels of hospitals，different drug varieties，different evaluation angles，etc.，such as the drug selection methods of one county hospital and one township hospital， methods and tools for different types of drugs such as antibacterial drugs，ibuprofen preparations，proton pump inhibitors and hypoglycemic drugs used in pediatric intensive care units， Chinese patent medicine selection tools， tools for evaluation from the perspective of pharmacoeconomics， and universal tools for selecting domestic medical institutions. The nine drug selection tools of foreign medical institutions were from the European，American，Asian and African countries. It was first published in 1955. The contents included the formulation standards that medical institutions should follow for drug prescription sets，the management formulation and update of hospital prescription sets，and drug evaluation tools. ConclusionOn the whole，the drug selection methods and institutional methods of foreign medical institutions developed earlier than those in China. In recent years，Chinese medical institutions have paid high attention to drug selection and released various types of drug selection tools. However，the standardization should be further improved in the future.

Gastric cancer is one of the most common malignant tumors worldwide,with its incidence and mortality rates ranking third among malignant tumors in China.Regulated cell death(RCD)is a type of cell death activated by signal transduction modules and closely connected to the progression and treatment of gastric cancer.Different types of RCD,comprising apoptosis,pyroptosis,ferroptosis,cuproptosis,and autophagy,not only aid in eliminating damaged cells,but also serve a crucial role in suppressing gastric cancer spread.This paper reviews different forms of RCD and their roles in the progression of gastric cancer,so as to provide reference for new diagnosis and treatment strategies of gastric cancer.

Objective To analyze the relationship between bone mineral density (BMD) of infants over 6 months of age and exclusive breastfeeding and calcium nutrition guidance during pregnancy in Baoding area, and to provide evidence for clinical application. Methods A total of 308 infants over 6 months of age were selected from Baoding Maternal and Child Health Hospital from January 2020 to January 2023, and their BMD was measured by ultrasound. The level of 25 (OH) D3 in subjects' blood was detected. spearman correlation test was used to analyze the correlation between infant bone mineral density and exclusive breastfeeding and calcium nutritional guidance during pregnancy, and logistics regression model was used to analyze the independent factors affecting infant bone mineral density. Results The level of serum 25 (OH) D3 in normal BMD group was significantly higher than that in abnormal BMD group (P<0.05). The rate of exclusive breastfeeding and the guidance rate of calcium nutrition during pregnancy in normal BMD group were significantly higher than those in abnormal BMD group (P<0.05). There was a significant positive correlation between different bone mineral density and exclusive breastfeeding and calcium nutrition guidance during pregnancy (P<0.05). Serum 25 (OH) D3 level, exclusive breastfeeding rate and calcium nutritional guideline rate during pregnancy were independent protective factors for bone mineral density (P<0.05). Conclusion Bone mineral density (BMD) of infants over 6 months of age is positively correlated with exclusive breastfeeding and calcium nutrition guidance during pregnancy, and exclusive breastfeeding and calcium nutrition guidance during pregnancy are independent protective factors affecting BMD of infants over 6 months of age.

OBJECTIVE To study the differences in toxicity between intravenous(iv)administration and aqueous solution exposure of Dichroa alkali salt(DAS)in zebrafish.METHODS ① Well-devel-oped zebrafish larvae of 2 d post fertilization(2 dpf)were randomly divided into the normal control(no treatment),solvent control(saline,iv),and DAS groups(0.125,0.25,0.50,1.00 and 2.00 mg·kg-1,iv)before being observed for 3 consecutive days after administration.A heart rate of 0 was determined as death of zebrafish,and the mortality rate,maximum non-lethal dose(MNLD),and 10 percent lethal dose(LD10)were calculated.The incidence of venous sinus congestion,pericardial edema,slowing heart rate and blood flow of zebrafish in the 0.50 and 2.00 mg·kg-1 groups were observed and calculated by somatoscopic microscopy at 4 h after drug administration.Zebrafish larvae were iv given DAS at doses of 0.041,0.136,0.412,and 0.452 mg·kg-1 while the malformation phenotypes of zebrafish larvae development were observed under a stereomicroscope for 3 consecutive days,including pericardial edema,abnormal heart rate,slow blood flow,loss of circulation,eye abnormalities,brain malforma-tions,jaw abnormalities,loss/degeneration of the liver,delayed yolk sac absorption,intestinal abnormal-ities,abnormal body coloration,body edema,curvature of the trunk/tail/nodal cord and muscle degener-ation before the incidence was calculated.②Zebrafish larvae were randomly divided into a normal control group and DAS aqueous solution exposure groups at concentrations of 2.5,5.0,10.0,25.0,50.0,75.0,and 100.0 mg·L-1,observed for 3 d until the mortality rate,LD10,and MNLD were calculated.Zebrafish were exposed to DAS aqueous solutions at concentrations of 0.32,1.06,3.20,and 11.00 mg·L-1,and the malformation phenotypes of zebrafish larvae development were observed under a stereomicro-scope for 3 consecutive days to calculate the incidence.RESULTS ① The MNLD and LD10 of DAS iv administered to zebrafish larvae were 0.412 and 0.452 mg·kg-1,respectively.Compared with the solvent control group,4 h after DAS iv administration,the incidence of sinus congestion,slow heart rate and pericardial edema in the 0.50 and 2.00 mg·kg-1 groups significantly increased(P<0.05,P<0.01),so was the incidence of slow blood flow in the 2.00 mg·kg-1 group(P<0.01).The rate of delayed yolk sac absorption was significantly increased in the 0.041,0.136,0.412,and 0.452 mg·kg-1 groups(P<0.05,P<0.01),so was the mortality rate in the 0.452 mg·kg-1 group(P<0.05),with pericardial edema observed in the dead zebrafish.② The MNLD and LD10 of DAS aqueous solution exposure for zebrafish larvae were 3.20 and 11.00 mg·L-1,respectively.Compared with the normal control group,the incidence of decreased heart rate and slow blood flow was significantly increased in the 3.20 and 11.00 mg·L-1 groups(P<0.01),so was the incidence of significantly darkened intestines in the 1.06,3.20,and 11.00 mg·L-1 groups(P<0.01).The incidence of delayed yolk sac absorption was significantly increased in the 0.32,1.06,3.20,and 11.00 mg·L-1 groups(P<0.05,P<0.01),so was the incidence of trunk curvature and lower jaw malformation in the 11.00 mg·L-1 group(P<0.01).CONCLUSION The toxic phenotypes of DAS are different between iv administration and aqueous solution exposure in zebrafish larvae.DAS aqueous solution exposure can not only lead to slow heart rate,slow blood rheology,delayed yolk sac absorption and intestinal blackening,but also induce neurodevelopmental toxicity.However,iv adminis-tration can effectively ward off significant gastrointestinal damage and neurodevelopmental toxicity.

Objective:To explore the efficacy of balloon dilation percutaneous kyphoplasty (PKP) combined with prying reduction bone grafting in the treatment of thoracolumbar fractures, and its impact on patients′neurological function.Methods:The clinical data of 184 patients with thoracolumbar fractures from March 2017 to May 2020 in Cangzhou Integrated Traditional Chinese and Western Medicine Hospital of Hebei Province were retrospectively analyzed. Among them, 86 patients were treated with balloon dilation PKP combined with prying reduction and bone grafting (combined group), and 98 patients were treated with open reduction decompression and internal fixation (internal fixation group). The intraoperative bleeding volume, surgical time, intraoperative fluoroscopy frequency, efficacy and complications were recorded. One year after surgery, X-ray films were taken to measure the height of the anterior border and posterior border of vertebral body and the Cobb angle, and the pain visual analogue score (VAS), Barthel index and neurological Frankel grade were evaluated.Results:The intraoperative bleeding volume and surgical time in combined group were significantly higher than those in internal fixation group: (205.64 ± 45.63) ml vs. (180.37 ± 30.08) ml and (110.22 ± 28.91) min vs. (81.66 ± 20.77) min, and there were statistical differences ( P<0.01); there was no statistical difference in intraoperative fluoroscopy frequency between the two groups ( P>0.05). The total effective rate in combined group was significantly higher than that in internal fixation group: 91.86% (79/86) vs. 79.59% (78/98), the total incidence of complications was significantly lower than that in internal fixation group: 13.95% (12/86) vs. 38.78% (38/98), and there were statistical differences ( P<0.05 or <0.01). The height of the anterior border and posterior border of vertebral body 1 year after surgery in combined group were significantly higher than those in internal fixation group: (95.78 ± 1.59) mm vs. (62.74 ± 1.80) mm and (98.53 ± 3.80) mm vs. (95.06 ± 3.28) mm, the Cobb angle was significantly smaller than that in internal fixation group: (6.53 ± 2.80)° vs. (18.06 ± 2.68)°, and there were statistical differences ( P<0.01). The VAS and Barthel index 1 year after surgery in both groups improved significantly, and there were statistical differences ( P<0.01), but there were no statistical differences between the two groups ( P>0.05). The rate of neurological Frankel grade E 1 year after surgery in combined group was significantly higher than that in internal fixation group: 56.98% (49/86) vs. 23.47% (23/98), and there was statistical difference ( P<0.01). Conclusions:Compared with open reduction decompression and internal fixation, the balloon dilation PKP combined with prying reduction and bone grafting patients with thoracolumbar fractures is better for vertebral reduction and deformity repair, with higher safety, more significant pain relief, and better recovery of daily life and neurological function.

Objective:To investigate the effect of different pressure balloon dilation combined with prying reduction and bone graft fixation in the treatment of thoracolumbar fractures and the risk factors of postoperative re-fracture.Methods:One hundred cases of thoracolumbar fracture patients admitted to Cangzhou Integrated Traditional Chinese and Western Medicine Hospital in Hebei Province from March 2019 to June 2021 were selected. Prospective randomized controlled study method was used and random number table method was used to divide them into three groups: incomplete expansion group (33 cases), moderate expansion group (33 cases) and complete expansion group (34 cases). All the 3 groups were treated with balloon dilation combined with prying reduction and bone graft fixation. The pressure of balloon dilation in incomplete dilation group, moderate dilation group and complete dilation group was 100 psi, 150 psi and no more than 200 psi respectively, and the volume of balloon dilation was 0.5∶1, 1∶1 and 1.5∶1 respectively. The operation time, intraoperative bleeding volume, postoperative drainage volume, vertebral anterior margin recovery rate and hospital stay, as well as local Cobb angle, visual analog scale (VAS) and Oswestry disability index (ODI) scores before and after operation were compared among the three groups. According to the follow-up of whether there is re-fracture after surgery, the clinical data of the re-fracture group and the non re-fracture group were compared, and the risk factors of the re-fracture after surgery were analyzed. The measurement data with normal distribution was expressed as: independent sample t-test was used for comparison between two groups, one-way ANOVA or repeated measurement ANOVA was used for comparison between three groups, and SNK-q test was used for comparison between two groups. Counting data were expressed in cases or cases (%), and compared between groups by χ 2 Inspection. Logistic regression was used to analyze the risk factors of refracture after thoracolumbar fracture. Results:There was no significant difference in operation time, intraoperative blood loss and postoperative drainage volume among the three groups ( P=0.096, 0.328 and 0.344, respectively). The recovery rate of vertebral anterior edge height in moderate expansion group was higher than that in incomplete expansion group and complete expansion group ((84.15±4.21)% vs (70.18±7.44)%, (75.94±6.56)%), and the hospitalization time was shorter than that in incomplete expansion group and complete expansion group ((10.38±2.35) d vs (15.18±3.44), (14.59±2.48) d) (all P<0.001). Before treatment, there was no significant difference in Cobb angle, VAS and ODI scores among the three groups (all P>0.05). After treatment, the Cobb angle, VAS and ODI scores of patients in the three groups were lower than those before treatment, and the moderate expansion group were lower than those in the incomplete expansion group and the complete expansion group ((14.08±2.15) ° vs (16.48±4.85) °, (15.06±3.45) °, (1.81±0.53)% vs (2.25±0.41), (2.31±0.42), (18.16±2.18)% vs (20.48±4.85), (20.01±4.45) points) (all P<0.001). 100 patients were followed up until the fracture was healed. They were divided into re-fracture group (15 cases) and non re-fracture group (85 cases) according to whether there was re-fracture after operation. The results of multifactor logistic regression analysis showed that body mass index and bone mineral density were protective factors for patients with thoracolumbar fracture after operation (odds ratio was 0.66 and 0.15 respectively, 95% confidence interval: 0.51~0.86, 0.05~0.42, P values were 0.006 and <0.001 respectively), The old wedge-shaped change of the vertebral body and the abnormal structure of the lumbar spine are the risk factors for postoperative re-fracture (odds ratio 4.22 and 6.36, 95% confidence interval 1.14-15.56 and 1.43-28.21, respectively, P values were 0.027 and 0.015). Conclusions:In the treatment of thoracolumbar fracture with prying reduction and bone grafting fixation, the effect of balloon expansion pressure of 150 psi is better. Body mass index (BMI) and bone mineral density (BMD) were protective factors for postoperative re-fracture of patients with thoracolumbar fracture. Old wedge-shaped change of vertebral body and abnormal lumbar structure are risk factors for postoperative re-fracture.

Objective:To investigate the pathological characteristics, treatment and prognosis of synovial sarcoma of head and neck.Methods:The clinical data of 24 patients with synovial sarcoma of the head and neck treated in the First Affiliated Hospital of Zhengzhou University from January 2012 to December 2020 were retrospectively analyzed. There were 16 males and eight females, aged 17 to 75 years. The pathological features, treatment and follow-up were summarized. Cumulative survival was estimated by Kaplan-Meier method.Results:All patients′ diagnoses were confirmed by pathological examinations. Most cases showed the tumors were composed of spindle cells under microscope, with the characteristics of malignant tumor cells, and some tumors also showed epithelioid cell morphology, forming the typical pathological characteristics of biphasic differentiation. Except for one patient who could not tolerate surgery and the diagnosis was only confirmed by biopsy, the remaining 23 patients received surgical treatment, including three patients receiving surgical treatment alone, five patients receiving post-operative adjuvant radiotherapy, seven patients receiving post-operative adjuvant chemotherapy, and eight patients receiving post-operative adjuvant radiotherapy. Follow-up time was 3.0-114.1 months (median follow-up time: 25.2 months), including two cases of loss to follow-up, 10 cases of recurrence, five cases of lung metastases, one case of bone metastasis, and 12 cases of death. The 1-year, 3-year and 5-year survival rates for the 24 patients with synovial sarcoma of head and neck were 74.4%, 58.9% and 39.2%, respectively.Conclusion:Synovial sarcoma of the head and neck has a high recurrence rate, common distant metastasis and poor prognosis. Histopathology and immunohistochemical examinations are an important basis for diagnosis, if necessary, combined with molecular genetics. Surgical resection is the main treatment, preferring radical or expanded resection.

Objective To evaluate the safety and efficacy of lenalidomide plus rituximab in treatment of the patients with relapsed/refractory B-cell non-Hodgkin lymphoma (B-NHL). Methods The clinical data of the patients with relapsed/refractory B-NHL after the varieties of treatment methods in Peking Union Medical College Hospital between January 2015 and December 2017 were retrospectively analyzed. All the patients were treated with R2 regimen: oral lenalidomide (25 mg/d for day 1-day 21) and rituximab (375 mg/m2 of intravenous infusion on day 1, 28-day of each cycle); the efficacy was evaluated after three cycles. After this induction phase, the patients achieving complete response (CR), partial response (PR), or stable disease (SD) were given R2 regimen until the end of 8 cycles. The major end point was overall response rate (ORR) defined as CR + PR. Secondary end point included 1-year progression free survival (PFS), 1-year overall survival (OS) and grade 3-4 adverse events. T cell and B cell subsets of 7 patients at baseline were measured, and T cell and B cell subsets of 13 patients with good efficacy were dynamically observed. Results A total of 49 patients who received 1-4 chemotherapy regimens were included. The ORR after the R2 treatment for 3 courses was 65% (32/49). Thirty-six patients (9 cases of CR, 22 cases of PR, 5 cases of SD) were enrolled in R2 maintenance treatment. The median follow-up time was 13 months, 1-year PFS rate was 61% and 1-year OS rate was 84% . The most common adverse event was bone marrow suppression, including grade 3-4 neutropenia (27% ), grade 3-4 thrombocytopenia (6% ) and grade 4 anemia (4% ), most of which could be controlled by prolonging interval cycles or reduced lenalidomide dosage. The decreased number of CD19+B cell after treatment could be seen in 13 patients who obtained good efficacy under the dynamic observation. Conclusion Lenalidomide plus rituximab is well tolerated and highly active in the treatment of relapsed/refractory B-NHL.
