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.

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.

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 Insomnia is the most fre-quent sleep disorder worldwide and the clinical applica-tion of therapeutic drugs has various adverse effects.In recent years,drugs developed from natural herbs have become potential alternative therapies for insomnia.Nuciferine,one of the main bioactive components obtained from the lotus leaves,has been reported to possess extensive pharmacological activities.However,its hypnotic and sleep regulatory effects have rarely been reported.Hence,this study was intended to investigate the pharma-cological effects of nuciferine and its mechanisms of action in insomnia.METHODS The hypnotic and seda-tive effects of nuciferine were investigated using the eval-uation of locomotor activity test and pentobarbital-induced sleep test in normal and serotonin(5-HT)depletion-induced insomniac mice.Furthermore,the sleep regulatory effects,including sleep time,sleep architecture,and δ-wave power spectral density,were explored using elec-troencephalography/electromyogram(EEG/EMG)-based sleep profiling in normal rats.Finally,the mechanisms of the hypnotic and sedative effects of nuciferine were explored usingin vivoand in silico experiments.RESULTS Nuciferine reduced locomotor activity and prolonged pen-tobarbital-induced sleep time in a dose-dependent man-ner in normal and insomniac model mice.Nuciferine sig-nificantly increased the total sleep time and non-rapid eye movement(NREM)sleep time,inhibited NREM sleep fragmentation,and improved delta power between 0.5 Hz and 1 Hz in normal rats.The results of molecular experiments showed that nuciferine could increase the 5-HT content and 5-HT1A receptor level in the hypothala-mus of insomnia model mice.CONCLUSION This study combined network pharmacological prediction and experi-mental pharmacological techniques to discover the seda-tive-hypnotic effect of nuciferine for the first time Nucif-erine can ameliorate sleep disorder in mice with insom-nia,possibly via serotonergic system.Nuciferine may rep-resent a novel treatment that alleviate the insomnia-like symptoms by modulating 5-HT system.

OBJECTIVE AMPK activator,act as exer-cise mimetics,effective in preventing or ameliorating met-abolic diseases,including obesity and diabetes.Systemic activating of AMPK represents an important therapeutic strategy to treat metabolic diseases.However,whether far-infrared(FIR)hyperthermia therapy could be used as exercise mimetic to realize wide-ranging metabolic regu-lation,and its underling mechanisms remain unclear.METHODS The mice were subjected to hyperthermia in the FIR chamber(30±1)℃for 14 d.Exercise endurance was determined using a treadmill.Blood flow were mea-sured by the laser speckle contrast imaging.Combina-tion of microbiomic and metabolomic analysis,diversity of microbiota and metabolic profiling in muscle were detected.The microbiota disorder model via treatment with different cocktails of antibiotics(ABX).RESULTS The material characterization shows that the graphene synthesized by chemical vapour deposition(CVD)is dif-ferent from carbon fi ber,with single-layer structure and high electrothermal transform efficiency.The emission spectra generated by graphene-FIR device would maxi-mize matching those adsorbed by tissues(≈8.0 μm).Gra-phene-FIR improves core and epidermal temperature,and increases blood flow in femoral muscle and abdo-men.The diversity of gut microbiota was increased by graphene-FIR exposure.Graphene-FIR reduced the bac-teroidetes/firmicutes(B/F)ratio and increased the abun-dance of short-chain fatty acids(SCFA)-producing bac-teria,including Allobaculum,Blautia and Anaerostipes.Additionally,graphene-FIR stimulated the expression of SCFAs-sensing receptor(GPR 43),p-AMPK Thr172 and GLUT4,and increased the AMP/ATP ratio,thus enhanc-ing muscle glucose uptake.Metabolomic analyses revealed the significant changes in 25 metabolites,with twenty increased(eg.creatinine and phosphate)and five decreased(eg.lactic acid),and the marked impact of five metabolic pathways,including galactose metabo-lism,glycolysis,gluconeogenesis,fatty acid biosynthesis,butanoate metabolism,pyruvate metabolism.Further-more,a microbiota disorder model also demonstrates that the graphene-FIR effectively restore the exercise endurance with enhanced p-AMPK and GLUT4.CON-CLUSION Our results provide convincing evidence that graphene-based FIR therapy promoted exercise capacity and glucose metabolism via AMPK in gut-muscle axis.These novel insights into graphene-FIR therapy suggest a potential as an exercise mimetic for the treatment of metabolic disease in clinical.

Objective:To observe the effects of acupuncture and moxibustion on phosphatase and PTEN-induced putative kinase 1(PINK1)/Parkin signaling pathway in the midbrain substantia nigra of Thy1-α synuclein(αSyn)transgenic model mice with Parkinson disease(PD). Methods:Twenty-four Thy1-αSyn transgenic mice were randomly divided into a model group,an acupuncture group,an acupuncture + moxibustion group,and a Western medicine group.Six wild-type mice in the same litter were used as the wild-type group.In the acupuncture group,Baihui(GV20)and Yanglingquan(GB34)were selected for acupuncture.In the acupuncture + moxibustion group,Guanyuan(CV4)was added on the basis of the acupuncture group.The Western medicine group was given rapamycin intraperitoneal injection at a dose of 10 mg/(kg·bw).The wild-type group and the model group were fixed without intervention.The overall rod performance(ORP)score of mice was observed in each group.The immunohistochemical method was used to detect the tyrosine hydroxylase(TH)positive neurons in the substantia nigra of mice in each group.The αSyn was detected by the immunofluorescence chemical method.The expression levels of αSyn,microtubule-associated protein 1 light chain 3(LC3)-Ⅱ/LC3-Ⅰ,autophagy protein sequestosome-1/protein 62(SQSTM-1/p62),PINK1,Parkin,and ubiquitin-specific protease 30(USP30)proteins were detected by Western blotting assay.The expression levels of LC3B,p62,PINK1,Parkin,and USP30 mRNAs were detected by fluorescence quantitative polymerase chain reaction. Results:Compared with the wild-type group,the ORP score,the p62,PINK1,and Parkin protein expression levels decreased significantly(P<0.01),the PINK1 mRNA expression level decreased(P<0.05),while the protein and mRNA expression levels of USP30 increased(P<0.05)in the model group.Compared with the model group,the ORP score in the acupuncture group and the acupuncture + moxibustion group increased(P<0.05);the expression level of LC3-Ⅱ/LC3-Ⅰ protein in the acupuncture + moxibustion group and the Western medicine group increased(P<0.05);the protein expression levels of p62,PINK1,and Parkin increased(P<0.05),while the USP30 protein expression level decreased significantly(P<0.01)in the acupuncture group,the acupuncture + moxibustion group,and the Western medicine group;the Parkin mRNA expression level in the acupuncture group and the acupuncture + moxibustion group increased(P<0.05);the USP30 mRNA expression level in the acupuncture + moxibustion group decreased(P<0.05). Conclusion:Acupuncture and moxibustion regulate the related molecule expression levels of PINK1/Parkin signaling pathway in the Thy1-αSyn transgenic PD model mice and promote the autophagy degradation of αSyn to exert the protective effect of dopaminergic neurons.

Background: Arctic-like (AL) lineages of rabies viruses (RABVs) remains endemic in some Arctic and Asia countries. However, their evolutionary dynamics are largely unappreciated. Objectives: We attempted to estimate the evolutionary history, geographic origin and spread of the Arctic-related RABVs. Methods: Full length or partial sequences of the N and G genes were used to infer the evolutionary aspects of AL RABVs by Bayesian evolutionary analysis. Results: The most recent common ancestor (tMRCA) of the current Arctic and AL RABVs emerged in the 1830s and evolved independently after diversification. Population demographic analysis indicated that the viruses experienced gradual growth followed by a sudden decrease in its population size from the mid-1980s to approximately 2000.Genetic flow patterns among the regions reveal a high geographic correlation in AL RABVs transmission. Discrete phylogeography suggests that the geographic origin of the AL RABVs was in east Russia in approximately the 1830s. The ancestral AL RABV then diversified and immigrated to the countries in Northeast Asia, while the viruses in South Asia were dispersed to the neighboring regions from India. The N and G genes of RABVs in both clades sustained high levels of purifying selection, and the positive selection sites were mainly found on the C-terminus of the G gene. Conclusions The current AL RABVs circulating in South and North Asia evolved and dispersed independently.

Vagus nerve reflex is a rare complication of percutaneous renal decompression. It is often induced by excessively rapid decompression of severe hydronephrosis and traction of the main nerves innervating the kidney. The clinical manifestations are irritability, sweating, clammy skin, hiccups, slow heart rate. It is easy to misdiagnose. In this study, 4 patients with vagus nerve excitement after percutaneous renal decompression were treated. After monitoring the patient’s vital signs and giving treatment such as expanding blood volume and raising blood pressure, the symptoms gradually disappeared.
