ObjectiveTo preliminarily explore the active components and target pathways of Angelicae Sinensis Radix-Polygonati Rhizoma （ASR-PR） herb pair in the treatment of simple obesity through network pharmacology and molecular docking， and to verify and investigate its mechanism of action via animal experiments. MethodsThe chemical constituents and targets of ASR and PR were predicted using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）. Targets related to simple obesity were identified by retrieving the GeneCards， Online Mendelian Inheritance in Man （OMIM）， Pharmacogenomics Knowledgebase （PharmGKB）， and DisGeNET databases. The intersection of drug and disease targets was used to construct an active component-target network using Cytoscape software. This network was imported into the STRING database to construct a protein-protein interaction （PPI） network， and topological analysis was conducted to identify core genes. Gene Ontology （GO） analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis and mapping were performed using the DAVID database and the Microbioinformatics platform. AutoDock 1.5.7 software was used to perform molecular docking between the top five active components and core targets. An animal model of simple obesity was established by feeding C57BL/6J mice a high-fat diet. The mice were administered ASR （2.06 g·kg^-1）， PR （2.06 g·kg^-1）， or ASR-PR （4.11 g·kg^-1） for 10 weeks， while the model group received an equal volume of purified water by gavage. After the administration period， the mice were sacrificed to measure body fat weight and serum levels of total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein （HDL）， and low-density lipoprotein （LDL）. Hematoxylin-eosin （HE） staining was used to observe histopathological sections of liver and adipose tissue. Serum levels of leptin， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） were determined by enzyme-linked immunosorbent assay （ELISA）， and the mRNA expression levels of epidermal growth factor receptor （EGFR） and signal transducer and activator of transcription 3 （STAT3） in liver tissue were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsNetwork pharmacology and molecular docking results indicated that the treatment of simple obesity by ASR-PR may involve the regulation of protein expression of core targets EGFR and STAT3 by its main components MOL009760 （Siberian glycoside A_qt）， MOL003889 （methyl protodioscin_qt）， MOL009766 （resveratrol）， MOL006331 （4′，5-dihydroxyflavone）， and MOL004941 （baicalin）， thereby modulating the PI3K/Akt and JAK/STAT signaling pathways. The animal experiment results showed that compared with the normal group， the model group had significantly increased body weight， body fat weight， and serum levels of TG， TC， TNF-α， IL-6， and leptin （P<0.01）. EGFR mRNA expression was significantly elevated （P<0.05）， while STAT3 mRNA expression was significantly decreased （P<0.01）. Histological analysis revealed disordered hepatic architecture in the model group， with pronounced lipid vacuoles， cytoplasmic loosening， lipid accumulation， and steatosis. Adipocytes in white adipose tissue （WAT） and brown adipose tissue （BAT） of the model group exhibited markedly increased diameters， reduced cell counts per unit area， and irregular morphology. Compared with the model group， the ASR-PR group significantly reduced body weight， body fat weight， serum TC， IL-6， TNF-α， leptin levels， and EGFR mRNA expression （P<0.01）. TG levels were also significantly decreased （P<0.05）， while STAT3 mRNA expression was significantly increased （P<0.01）. Histopathological improvements included reduced size and number of hepatic lipid vacuoles and restoration of liver cell morphology toward that of the normal group. The diameter of adipocytes significantly decreased， and the number of adipocytes per unit area increased. ConclusionASR-PR may regulate the expression of key target proteins such as EGFR and STAT3 via its core active components， modulate the PI3K/Akt and JAK/STAT signaling pathways， repair damaged liver and adipose tissues， and thereby alleviate the progression of obesity in mice.

Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Objective:To explore the protective effect and mechanism of Tongfu Lifei decoction (TFL) on human monocytic leukemia cell THP-1 induced by lipopolysaccharide (LPS).Methods:① THP-1 cells were cultured in vitro, and incubated with 1 mg/L LPS for 18 hours to construct an in vitro THP-1 cell inflammation model. Other THP-1 cells were taken as blank control group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6) secreted by cells. ② THP-1 cells were divided into seven groups and treated with 0, 0.005, 0.01, 0.02, 0.04, 0.08, and 0.16 mL/mL TFL for 24 hours (added different dosages of TFL solution per milliliter of culture medium, with a crude drug content of 1 kg/L). The cell survival rate was detected using methyl thiazolyl tetrazolium (MTT) colorimetric method, and the intervention dosage of TFL for its non-toxic effect on THP-1 cells was screened. ③ Another THP-1 cells were divide into inflammatory model group and 0.01, 0.02, and 0.04 mL/mL TFL groups according to the intervention dosage of TFL screened by MTT colorimetry. After 24 hours of intervention, the levels of TNF-α and IL-6 secreted by cells were measured using ELISA. Western blotting was used to detect the expressions of programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) signaling pathway proteins in cells. Real time fluorescence quantitative reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expressions of microRNAs (miR-146a, miR-146b, miR-155) in cells. ④ The maximum non-toxic concentration of TFL (0.04 mL/mL) on the THP-1 cell was selected as the intervention dose. THP-1 cells were divided into inflammation model group, TFL group, TFL+miR-146a inhibitor group, TFL+miR-146b inhibitor group, and TFL+miR-155 inhibitor group. The inflammation model group was not given any drug intervention. The other inhibitor groups were added 100 nmol/L corresponding inhibitor. After 24 hours of intervention, the levels of TNF-α and IL-6 secreted by cells were measured using ELISA. Western blotting was used to detect the expressions of PD-1/PD-L1 signaling pathway proteins in cells. Results:① Compared with the blank control group, the levels of TNF-α and IL-6 secreted by cells in the inflammatory model group were significantly increased, indicating the successful construction of the THP-1 inflammatory cell model in vitro. ② 0-0.04 mL/mL TFL had no toxic effect on THP-1 cells. However, the survival rates of cells in the 0.08 mL/mL and 0.16 mL/mL TFL groups were significantly lower than those in the inflammation model group, indicating that TFL dosages exceeding 0.04 mL/mL had toxic effects on THP-1 cells. ③ Compared with the inflammation model group, 0.01 mL/mL TFL had no significant effect on the levels of TNF-α and IL-6 secreted by THP-1 cells, while intervention with 0.02 mL/mL and 0.04 mL/mL TFL significantly reduced the levels of TNF-α and IL-6 secreted by cells [TNF-α(ng/L): 95.89±8.55, 70.73±11.70 vs. 137.10±7.19, IL-6 (ng/L): 23.03±2.55, 16.58±1.72 vs. 32.60±2.55, all P < 0.01]. Compared with the inflammation model group, the expressions of PD-1/PD-L1 signaling pathway proteins in THP-1 cells in different dosages of TFL groups were significantly reduced, and showed a certain dosage dependence. The expressions of the pathway proteins in the 0.04 mL/mL TFL group were significantly lower than those in the inflammation model group [PD-1 protein (PD-1/β-actin): 0.28±0.04 vs. 1.00±0.10, PD-L1 protein (PD-L1/β-actin): 0.54±0.05 vs. 1.00±0.08, phosphoinositide 3-kinase (PI3K) protein (PI3K/β-actin): 0.28±0.03 vs. 1.00±0.08, phosphorylated protein kinase B (p-Akt) protein (p-Akt/Akt): 0.38±0.04 vs. 1.00±0.10, all P < 0.01]. Compared with the inflammation model group, the expression of miR-146a in THP-1 cells in the 0.01, 0.02, and 0.04 mL/mL TFL groups was significantly reduced (2 -ΔΔCt: 0.46±0.11, 0.31±0.13, 0.23±0.14 vs. 1.01±0.18, all P < 0.01), while there was no significant change in the expressions of miR-146b and miR-155. ④ Compared with the inflammation model group, the TFL group showed a significant decrease in the levels of TNF-α and IL-6 secreted by THP-1 cells. The miR-146a inhibitor could significantly reverse the inhibitory effect of TFL on inflammatory factors, and the difference was statistically significant as compared with the TFL group [TNF-α (ng/L): 138.55±10.30 vs. 72.33±10.59, IL-6 (ng/L): 31.35±3.98 vs. 15.75±3.76, both P < 0.01]. Compared with the inflammation model group, the expressions of PD-1/PD-L1 signaling pathway proteins in THP-1 cells in the TFL group were significantly reduced. The expressions of pathway proteins in cells in the TFL+miR-146a inhibitor group were significantly higher than those in the TFL group [PD-1 protein (PD-1/β-actin): 0.85±0.09 vs. 0.37±0.04, PD-L1 protein (PD-L1/β-actin): 0.83±0.08 vs. 0.55±0.06, PI3K protein (PI3K/β-actin): 0.85±0.09 vs. 0.63±0.06, p-Akt protein (p-Akt/Akt): 0.98±0.10 vs. 0.75±0.07, all P < 0.05]. Conclusion:TFL regulates the expression of miR-146a to inhibit the PD-1/PD-L1 signaling pathway in THP-1 cells, regulates the immune barrier of sepsis induced in cell inflammation model in vitro, and thus protects LPS induced THP-1 cells.

OBJECTIVE To clarify the core content of traditional Chinese medicine （TCM） policy in the provinces of China， so as to provide reference for optimizing the structure of the policy system of traditional Chinese medicine in China and assisting the inheritance and innovation of TCM industry in various regions. METHODS The websites of directly affiliated organs in 31 provinces， excluding Hong Kong， Macao and Taiwan， were retrieved to collect the TCM policies released from 2000 to 2021. The importance of keywords in the TCM policies of each province was measured based on term frequency-inverse documentation frequency （TF-IDF） keyword extraction method， and the similarities and differences were analyzed among TCM policies. RESULTS & CONCLUSIONS A total of 99 documents related to TCM policies of various provinces were obtained in this study， most of which were released after 2016. The theme of national TCM policy covered four aspects： building TCM talent team， perfecting TCM service system， strengthening TCM resource management and promoting TCM industry innovation. The TF-IDF values of “medical institutions”“traditional Chinese medicine”“medical treatment” were higher than other keywords in each province， indicating that the provinces paid more attention to the construction of TCM service system and the management of TCM resources than other aspects. Anhui and Jiangsu， Beijing and Henan， Hubei and Jilin， Hubei and Tianjin， and Hubei and Yunnan had the more degree of similarity in TCM policies， which all contained 16 of the same keywords. Therefore， the above regions should be encouraged to strengthen exchanges and cooperation and realize mutual promotion and joint development. Among all the keywords whose importance ratio was greater than 0.2，“ Tibetan medicine” was unique to Qinghai and Tibet，“ disease type” was unique to Guangdong， and the TF-IDF value of “supervision and management” in Beijing was higher， indicating that the emphasis of TCM policy formulation in different provinces was various. Meanwhile， the top 10 keywords of TF- IDF value in all provinces did not have words related to financial input， and the TF-IDF values of “informatization” in most provinces did not rank at the top. It is suggested to increase financial input or encourage social financing， and add “Internet+new business” in the field of TCM.

Non-alcoholic fatty liver disease （NAFLD） is a chronic liver disease with complex and diverse pathogenesis， and there is no effective treatment or specific drugs for its clinical treatment. In recent years， its incidence has been on the rise， and it has become the earnest expectation of medical researchers in China and abroad that related patients could be treated. AMP-activated protein kinase （AMPK） functions to regulate cellular energy homeostasis and mitochondrial homeostasis. When activated， it has a good intervention effect on NAFLD progression with lipid metabolism disorders and mitochondrial homeostasis disorders. For NAFLD， the activation of AMPK can inhibit the production of new lipogenesis in the liver， promote the oxidation of fatty acids in the liver， and enhance the mitochondrial function of adipose tissues. As a key target of metabolic diseases， AMPK can also improve apoptosis， liver fibrosis， autophagy， and inflammation. Traditional Chinese medicine （TCM） is good at treating diseases from multiple targets and multiple pathways and is also commonly used in the treatment of chronic liver disease in clinical practice. A large number of in vitro and in vivo experimental studies on NAFLD have shown that TCM monomers have good prospects for the treatment of NAFLD through the AMPK signaling pathway， including glycosides， phenols， alkaloids， flavonoids， quinones， terpenoids， and lignans， which are natural activators of AMPK. This study reviewed the research progress on TCM monomers in regulating the AMPK pathway to prevent and treat NAFLD， providing a broader perspective for TCM treatment of NAFLD.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

This article summarized the chemical components and pharmacological activities of S. oblata, providing a scientific rationale for its bioactive constituents, quality control, and utilization as an important medicine.

BACKGROUND: Lung cancer is the main cause of cancer-related death globally. Single nucleotide polymorphism (SNP) is one of the important factors leading to the occurrence of lung cancer, but its mechanism has not been elucidated. This study intends to investigate the relationship between SNPs of CDH1, FANCB, APC genes and lung cancer genetic susceptibility. METHODS: The case-control study design was used. We collected blood samples from 270 lung cancer cases in the Department of Lung Cancer Surgery, Tianjin Medical University General Hospital, as well as blood samples from 445 healthy volunteers as controls, and extracted genomic DNA for genotyping using the Taqman® SNP genotyping kit. The distribution of three SNP loci of CDH1 gene rs201141645, FANCB gene rs754552650 and APC gene rs149353082 in Chinese population was analyzed. Chi-square test and Logistic regression were used to analyze the relationship between different genotypes and the risk of lung cancer. RESULTS: The distribution frequencies of AA, A/G and GG genotypes at rs754552650 of FANCB gene in the control group were 27.2%, 52.6% and 20.2%, respectively. The distribution frequencies of AA and A/G genotypes were 93.7% and 6.3% in the case group, respectively, and no GG genotype was detected. The A/G genotype of the rs754552650 locus of the FANCB gene was significantly different between the case group and the control group. Compared with the carriers of AA genotype, the individuals with FANCB rs754552650 A/G genotype had a lower risk of lung cancer (OR=0.035, 95%CI: 0.020-0.062, P<0.001). CDH1 gene rs201141645 A/C and CC genotypes only existed in the control group. In addition, only 1 sample was found to have APC rs149353082 genotype in the case group. CONCLUSIONS In the Chinese population, the lung cancer risk of the individuals with FANCB rs754552650 A/G genotype was significantly decreased.
