Non-human primates are the closest relatives of human beings and possess similar morphological， anatomical， physiological， and behavioral characteristics， making them indispensable in fields such as neuroscience， reproduction， infectious diseases， and drug research and development. Currently， the restrictions on using non-human primates in experiments are becoming increasingly stringent in Europe and the United States. These experiments have ethical particularities that are different from those involving ordinary animals， and they also pose ethical challenges such as lack of necessity assessment， no unified assessment standards， and ethical dumping hazards. Supervision and ethical review should be strengthened. The key points of their ethical review include the necessity of the experiments， the assessment of the harm-benefit ratio， and the implementation of the “3R” principles.

ObjectiveTo investigate the material basis of homologous and heterogeneous effect of Aurantii Fructus Immaturus（AFI） and Aurantii Fructus（AF） based on the total statistical moment analysis and molecular connectivity index（MCI）. MethodRelevant literature at home and abroad and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP） were consulted to establish the chemical composition database of AFI and AF， and set up their fingerprints by ultra-high performance liquid chromatography（UPLC）， and the total statistical moments and similarity parameters of the fingerprint were calculated. According to MCI， all components of AFI and AF were divided into different component groups， the average values of 0-8^th order（⁰χ-⁸χ） MCI of the common component groups of AFI and AF were calculated. ResultThe values of total zero-order moment（AUC_T） of AFI and AF were （10.57±2.45）×10⁶， （5.09±0.89）×10⁶ μV·s， the values of total first-order moment（MCRT_T） were （11.57±1.58）， （12.10±1.29） min， the values of total second-order moments（VCRT_T） were（24.49±2.30）， （26.49±2.54） min²， respectively. It showed that qualitative and quantitative parameters of AFI and AF were significantly different. The components with high similarity such as neohesperidin， hesperidin and narirutin were screened as the common potential pharmacodynamic components of AFI and AF. The non-common components of AFI， such as alysifolinone and imperatorin， and the non-common components of AF， such as neoeriocitrin and isosakuranin， with high similarity were screened out as potential heterogeneous components of AFI and AF. The composition groups of AFI and AF were classified into six categories， and the similarities between the composition groups of AFI and AF and the total constituents were 0.872-0.979 and 0.918-0.997， the average values of ⁰χ-⁸χ MCI of alkaloids in AFI and AF were 3.65 and 3.14， the average values of ⁰χ-⁸χ MCI of flavonoids were 8.47 and 8.47， the average values of ⁰χ-⁸χ MCI of volatile oils were 2.71 and 3.48， respectively. It showed that there were some differences in MCI of chemical constituents（groups） between AFI and AF. ConclusionThe chemical constituents（groups） of AFI and AF not only differ in content and species， but also in structural characteristics and structure-activity relationship， which can provide a basis for further explaining the scientific connotation of homologous and heterogeneous effect of AFI and AF.

The tumor microenvironment includes blood vessels， lymph， nerves， non-malignant cells， and their metabolites at and near the tumor lesion site， which interact with cancer cells and promote cancer progression. Rapid proliferation of cancer cells increases oxygen consumption， or abnormalities in the structure and function of blood vessels in solid tumors lead to a decrease in oxygen supply， forming a hypoxia microenvironment. The existence of a hypoxia microenvironment is a typical pathophysiological feature of locally advanced solid tumors， widely present in various types of human malignant tumors. Hypoxia microenvironment is a sign of tumor microenvironment and an important and complex system in the breast tumor microenvironment. Its formation and development are closely related to the growth of breast cancer， occupying an important position in the research and treatment of breast cancer. With its advantages of multiple pathways and multiple targets， the effective monomer and compound of traditional Chinese medicine can better regulate the hypoxia microenvironment of breast cancer， inhibit the proliferation， invasion， and metastasis of breast cancer cells in the hypoxia environment， induce apoptosis， reverse their drug resistance， intervene in the metabolic reprogramming of breast cancer cells in the hypoxia environment， and inhibit their angiogenesis， thereby improving the quality of life of patients to a certain extent and prolonging the survival cycle of patients. This paper first summarized and discussed the effects of hypoxia microenvironment on proliferation， invasion， metastasis， drug resistance， immune function， metabolic reprogramming， non-coding RNA， iron death， and autophagy of breast cancer cells， which affected the occurrence and development of breast cancer， and it elaborated the mechanism behind it. Then， the paper elucidated the regulatory effect and mechanism of targeting the hypoxia microenvironment based on the two modes of effective monomer and compound of traditional Chinese medicine， so as to analyze and extract the deficiencies and directions of traditional Chinese medicine in regulating the hypoxia microenvironment and provide a theoretical reference for the effective treatment of breast cancer.

Objective Air pollution is a leading public health issue.This study investigated the effect of air quality and pollutants on pulmonary function and inflammation in patients with asthma in Shanghai. Methods The study monitored 27 asthma outpatients for a year,collecting data on weather,patient self-management[daily asthma diary,peak expiratory flow(PEF)monitoring,medication usage],spirometry and serum markers.To explore the potential mechanisms of any effects,asthmatic mice induced by ovalbumin(OVA)were exposed to PM2.5. Results Statistical and correlational analyses revealed that air pollutants have both acute and chronic effects on asthma.Acute exposure showed a correlation between PEF and levels of ozone(O3)and nitrogen dioxide(NO2).Chronic exposure indicated that interleukin-5(IL-5)and interleukin-13(IL-13)levels correlated with PM2.5 and PM10 concentrations.In asthmatic mouse models,exposure to PM2.5 increased cytokine levels and worsened lung function.Additionally,PM2.5 exposure inhibited cell proliferation by blocking the NF-κB and ERK phosphorylation pathways. Conclusion Ambient air pollutants exacerbate asthma by worsening lung function and enhancing Th2-mediated inflammation.Specifically,PM2.5 significantly contributes to these adverse effects.Further research is needed to elucidate the mechanisms by which PM2.5 impacts asthma.

OBJECTIVE To investigate the effect of Jiawei Tianwang Buxin Dan(JWBXD)on insomnia in rats exposed to simulated high-altitude conditions.METHODS ① Thirty SD rats were randomly divided into the normal control,model,model+Jiawei Tianwang Buxin Dan(JWBXD,9.6 mg·kg-1),model+Tianwang Buxin Dan(TWBXD,9.6 mg·kg-1),and model+diazepam(DZP,3 mg·kg-1)groups.Rats,except for the normal control group,were subjected to a low-pressure,low-oxygen animal experimental chamber simulating a 5000 m altitude.Respective drugs were ig administrated once daily at 9:00 for seven days,and signal acquisition and sleep analysis were conducted by a wireless physiological sig-nal telemetry system.②Forty rats were randomly divided into five groups as described in ①.Through-out the experiment,the general condition and body mass of the rats were observed daily.Drug adminis-tration lasted for seven days,and grip strength was tested one hour after the final administration.ELISA was used to measure the levels of corticotropin-releasing hormone(CRH),adrenocorticotropic hor-mone(ACTH),corticosterone(CORT),and melatonin(MLT)in serum.Western blotting was performed to measure the expression levels of core clock proteins period circadian regulator 2(Per2),circadian locomotor output cycles(Clock),cryptochrome 2(Cry2),brain-muscle arnt-like protein 1(Bmal1),nuclear receptor subfamily 1,group D member 1(NR1D1),glycogen synthase kinase-3β(GSK-3β),as well as acetylserotonin O-methyltransferase(ASMT)in the hypothalamus and pineal gland,respectively.RESULTS ① Compared with the normal control group,the model group exhibited a decrease in total sleep time(P<0.01),an increase in wakefulness(P<0.01),a significant reduction in slow wave sleep(SWS)(P<0.05)and the mean bouts duration(P<0.05).Compared with the model group,both DZP and JWBXD(P<0.01)prolonged sleep time and suppressed wakefulness(P<0.01)in the hypoxic envi-ronment.DZP and JWBXD prolonged SWS(P<0.05,P<0.01),while TWBXD had no significant effect.JWBXD improved the mean bouts duration of SWS in the model rats(P<0.01),whereas no such improvement was observed in model+DZP and model+TWBXD groups.② Compared with the normal control group,the model group showed a significant decrease in forelimb grip strength(P<0.01),increased levels of serum ACTH(P<0.05),CRH,and CORT(P<0.01),and decreased MLT levels(P<0.05).The expression levels of Per2,Cry2,GSK-3β,and NR1D1 in the hypothalamus were downregu-lated(P<0.05,P<0.01),while Bmal1 and Clock were upregulated(P<0.05,P<0.01).ASMT expression in the pineal gland was decreased(P<0.05).Compared with the model group,JWBXD and TWBXD enhanced forelimb grip strength(P<0.01),reduced serum CORT and ACTH levels(P<0.05),decreased CRH levels(P<0.01),and restored MLT levels(P<0.01).JWBXD upregulated the expression levels of Per2,Cry2,GSK-3β and NR1D1 in the hypothalamus(P<0.05,P<0.01),but downregulated Bmal1 and Clock expression(P<0.05,P<0.01).TWBXD downregulated Bmal1 expression in the hypothalamus(P<0.01)and increased NR1D1 expression(P<0.05).DZP significantly enhanced the expression levels of Per2,Cry2 and NR1D1 in the hypothalamus(P<0.01).JWBXD,TWBXD and DZP improved ASMT expression in the pineal gland(P<0.05).CONCLUSION JWBXD can improve sleep structure and prolong the duration of SWS in rats exposed to simulated high-altitude conditions.The mechanisms may involve the regulation of core clock protein expressions in the hypothalamus,promotion of mela-tonin secretion,and inhibition of HPA axis hyperactivity.

Objective:To compare the clinical efficacy of axillary transthoracic approach and posterior approach in the treatment of upper thoracic tuberculosis with vertebral clearance, bone graft fusion, and internal fixation surgery.Methods:Fifty five patients with upper thoracic tuberculosis admitted to Changsha Central Hospital, University of South China from March 2017 to March 2022 were selected and divided into axillary transthoracic group and posterior group according to different surgical approaches. The incision length, surgical time, intraoperative blood loss, and postoperative hospitalization time were compared between the two groups of patients. Two groups of patients were recorded for preoperative and postoperative pain visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores at 1 week, 3 months, and 12 months, preoperative and postoperative serum inflammatory indicators, CD4 + /CD8 + ratio of T lymphocyte subsets, and complications. Results:The incision length, operation time, and intraoperative blood loss in the axillary transthoracic group were significantly less than those in the posterior group, and the differences were statistically significant (all P<0.05). However, there was no statistically significant difference in postoperative hospitalization time between the two groups of patients ( P>0.05). The VAS and ODI scores of the two groups of patients showed significant improvement compared to preoperative levels at 1 week, 3 months, and 12 months after surgery (all P<0.05); And at 1 week and 3 months after surgery, the VAS scores of patients in the axillary transthoracic group were significantly lower than those in the posterior group (all P<0.05), and the ODI scores at 3 and 12 months after surgery were significantly lower than those in the posterior group (all P<0.05). The erythrocyte sedimentation rate and CRP levels of both groups of patients increased significantly one week after surgery compared with preoperative levels (all P<0.05), but the erythrocyte sedimentation rate and CRP levels basically returned to normal levels at three months after surgery. The CD4 + /CD8 + ratio of T lymphocyte subsets in both groups was lower than preoperative levels at one week after surgery, but with the continuation of treatment, the CD4 + /CD8 + ratio increased significantly at three months after surgery. Conclusions:Both axillary and posterior approaches can be used for surgical treatment of upper thoracic tuberculosis, but axillary and thoracic approaches have the advantages of less trauma, less bleeding, and faster recovery.

Objective:To evaluate the reliability and validity of different quantitative methods based on CT images to evaluate the proportion of shoulder glenoid defect.Methods:Four shoulder joint specimens with no trauma, osteoarthritis or deformity were used, including 2 females and 2 males; the average age of death was 58±10 years old; all the specimens were prepared with a standard method with no bone defect occurring before preparation. A glenoid bone defect model was established with each specimen being cut into four defect gradient defects of approximately 8%, 16%, 24%, and 32% in proportion in sequence. A total of 16 samples were obtained. Physical photography and CT image reconstruction were performed on the 16 samples respectively. A total of 8 quantitative methods were used to quantify bone defects, which were surface area method, superimposed circle method, Barchilon method, Pico method, Shaha method, Griffith method, Sugaya method, and Giles method. Intraclass correlation (ICC) using a consistency model was used to evaluate reliability. Paired t-test was used to evaluate validity, with the physical measurement of the specimens using the surface area method as the reference standard. Result:The consistency ICC of each quantitative method was greater than 0.9, and all had high reliability. Combining the results of all bone defect gradients and imaging images, the surface area method had the best validity, which was 0.83%±0.75%; the Barchilon method came second, which was 0.91%±0.93%; the superimposed circle method and the Pico method had good validity, which were 0.99%±0.87% and 1.27%±1.09%, respectively; the Shaha method, the Griffith method, and the Sugaya method had poor validity, which were 6.11%±1.56%, 5.06%±1.35%, and 6.02%±1.61%, respectively; the Giles method had the worst validity, which was 8.40%±3.08%. Conclusion:In clinical practice, surface area method and superimposed circle method are the most reliable to quantify the proportion of bone defect if they can be performed. Otherwise, linear measurement of Barchilon method is the favored method while PICO method is the favored method for angle measurement.

ResultSimilarities of the total statistical moments of UPLC fingerprint of 15 batches of medicinal materials and decoction pieces were>0.89， the relative standard deviations（RSDs） of information entropy of UPLC fingerprint of 12 medicinal materials and decoction pieces were<10%. RSDs of total first-order moment（MCRT_T） and information entropy of Shentong Zhuyutang（medicinal materials） were 5.5% and 2.3%， while the RSDs of MCRT_T and information entropy of Shentong Zhuyutang（decoction pieces） were 4.8% and 2.6%， respectively. The dry extract rate of 45 batches of Shentong Zhuyutang was 17.2%-20.2%. The transfer rate of medicinal materials to decoction pieces was within the range of data fluctuation， which was 70%-130% of the average value. The overall transfer rates of medicinal materials to decoction pieces and decoction pieces to benchmark samples were 101.8% and 83.0%， respectively. ConclusionThe quality properties of Shentong Zhuyutang benchmark samples can be studied by total statistical moment analysis and primary feeding amount analysis， which can confirm the supramolecular "imprinting template" theory to a certain extent.

ObjectiveTo compare the similarities and differences of material basis for improving insulin resistance （IR） in different parts of Morus alba based on liquid-mass combination combined with network pharmacology and molecular docking technology. MethodUltra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF-MS） was used to analyze the composition differences in different parts of M. alba. Sybyl-X2.1 was used to connect components with IR core targets， and the selection criterion was Total Score≥5. The "component-target-disease" network map was drawn. The total statistical moment standard similarity （TQSMSS） between the single target-component docking score data set and the total target-component docking score data set was calculated. The targets with higher TQSMSS were screened out， and the protein-protein interaction （PPI） network was constructed. The Gene Ontology （GO） functional analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis were performed using R language. ResultForty-one active components were obtained by UPLC-Q-TOF-MS. According to the total statistical moment （similarity） method， there were 20， 23， 30， and 27 targets with TQSMSS≥0.75 in Mori Ramulus， Mori Cortex， Mori Fructus， and Mori Folium， respectively. In the four M. alba medicinal sources， the functional order of the targets by GO enrichment analysis was Mori Fructus>Mori Folium>Mori Cortex>Mori Ramulus， which were involved in biological processes such as blood glucose homeostasis， glucose metabolism， and glucose transmembrane transport. The order of the four M. alba medicinal sources by KEGG pathway enrichment analysis was Mori Fructus>Mori Ramulus>Mori Folium>Mori Cortex， which were involved in the adenosine monophosphate-activated protein kinase （AMPK） energy metabolism signaling pathway， the insulin regulation-related signaling pathway， the anti-inflammatory and anti-oxidative stress signaling pathway， and so on. ConclusionThis research demonstrates that there are differences in the material basis for improving IR by different parts of M. alba， which provides references for the development of different parts of M. alba.
