Objective:To analyze the effect of limb rehabilitation therapy combined with transcranial magnetic stimulation therapy on muscle activity in patients with upper limb dysfunction after cerebral infarction(CI).Methods:320 patients with upper limb dysfunction after CI were selected,all of whom were treated in our hospital between June 2021 and June 2023.They were randomly grouped according to the lottery method into the control group(limb rehabilitation therapy,160 cases)and the intervention group(transcranial magnetic stimulation therapy+limb rehabilitation therapy,160 cases).The upper limb function scores,neuro-electrophysiological indicators,daily living ability scores,and quality of life scores of the two groups were compared.Results:Compared with the control group,upper limb function scores and daily living ability scores in the intervention group were higher after treatment,and the neuro-electrophysiological indicators of the intervention group were lower after treatment(P<0.05).Conclusion:Transcranial magnetic stimulation therapy combined with limb rehabilitation therapy has significant effects in patients with upper limb dysfunction after CI and is worthy of promotion and application.

Experimental Study on Anatomic Reduction of Lateral Pterygoid Muscle(Simulated Manipulation Fracture Reduction)and Condylar Free Reduction for Condylar Fracture

[Objectives]To compare the fracture healing of keeping lateral pterygoid muscle anatomic reduction(simulated manipulation fracture reduction)with condylar free reduction in the treatment of condylar fractures.[Methods]Twenty-four New Zealand rabbits were randomly divided into two groups to mandibular condylar neck fracture model was established.one team keep the lateral pterygoid muscle,the other excise it.Cervical vascular perfusion was done with ink before animals executed after operation 2,4,6 and 8 weeks.Bilateral anteroposterior and mediolateral condylar diameters measured.Changes of operation side condylar proliferating layer,microvessel number and bone parameters were observed and analyzed after slices and HE staining.[Results]The mediolateral condylar diameters of operation side were significantly smaller than health side in condylar free reduction group at the 4,6,8 weeks(P<0.05),but there was no statistical difference in the anteroposterior condylar diameters at each time point(P>0.05).There were no significant differences in the anteroposterior and mediolateral condylar diameters of the anatomic reduction lateral pterygoid muscle group compared between the operation side and health side(P>0.05).The number of microvessel in condylar free reduction group were smaller than those in anatomic reduction lateral pterygoid muscle group(P<0.05).There were significant differences in BV/TV,Tb.Th,Tb.Sp between the condylar free reduction group and the anatomic reduction lateral pterygoid muscle group(all P<0.05),and the Tb.N were significantly differences between two groups at the 4,6,8 weeks(P<0.05).[Conclusions]When the condyle is fractured it should keep lateral pterygoid muscle(manipulation fracture reduction)as possible,which is important in the fracture healing and functional recovering of mandibular.

Observation on Therapeutic Effect of Erxian Decoction on Relieving Low Back Pain after PVP of PMOP-derived Vertebral Fracture

[Objectives]To explore the clinical effect of Erxian decoction on relieving low back pain after percutaneous vertebroplasty(PVP)of vertebral compression fracture caused by postmenopausal osteoporosis(PMOP).[Methods]Ninety patients who were treated in Suzhou TCM Hospital from September 2021 to January 2023 were randomly divided into three groups:traditional Chinese medicine group(n=30),western medicine group(n=30)and blank group(n=30).The patients in all the three groups were treated with basic anti-osteoporosis drugs.The patients in the traditional Chinese medicine group were treated with Erxian decoction after PVP,and those in the western medicine group were treated with celecoxib to relieve pain after operation.The visual analogue(VAS)score,Oswestry dysfunction index(ODI)score,TCM syndrome score and serum indexes such as interleukin-6(IL-6)and estrogen E2 were recorded before treatment and 2 weeks,1 month and 3 months after treatment.[Results](i)In terms of pain relief,the VAS score of the western medicine group was lower than that of the traditional Chinese medicine group after 2 weeks of treatment,but there was no significant difference in VAS score between the two groups after 1 month and 3 months,and the pain improvement of the two groups was better than that of the blank group.(ii)After 3 months of treatment,the ODI score in the traditional Chinese medicine group was lower than that in the western medicine group,and the improvement of TCM syndrome in the traditional Chinese medicine group was better than that in the other two groups 1 and 3 months after treatment(P<0.05).(iii)The level of IL-6 in the western medicine group was lower than that in the other groups after 2 weeks,and there was no significant difference between the two groups after 3 months of treatment.After 3 months of treatment,the level of E2 in the traditional Chinese medicine group was higher than that before treatment and higher than that in the western medicine group and the blank group,but there was no significant difference between the two groups(P>0.05).[Conclusions]Both Erxian decoction and non-steroidal anti-inflammatory drugs can relieve residual low back pain after PVP,and their long-term effects are similar,but Erxian decoction has more advantages in alleviating pain,muscle and joint pain and sensory abnormalities in postmenopausal women.Moreover,it is safe and reliable,and is worthy of clinical application.

A Comparative Analysis of the Chloroplast Genomes of Four Salvia Medicinal Plants

Herbgenomics is an emerging field of traditional Chinese medicine(TCM)research and development.By combining TCM research with genomics,herbgenomics can help to establish the scientific validity of TCM and bring it into wider usage within the field of medicine.Salvia Linn.(S.Linn.)is a large genus of Labiatae that includes important medicinal plants.In this herbgenomics study,the complete chloroplast(cp)genomes of two Salvia spp.—namely,S.przewalskii and S.bulleyana,which are used as a surrogate for S.miltiorrhiza—were sequenced and compared with those of two other reported Salvia spp.—namely,S.miltiorrhiza and S.japonica.The genome organization,gene number,type,and repeat sequences were compared.The annotation results showed that both Salvia plants contain 114 unique genes,including 80 protein-coding,30 transfer RNA(tRNA),and four ribosomal RNA(rRNA)genes.Repeat sequence analysis revealed 21 forward and 22 palindromic sequences in both Salvia cp genomes,and 17 and 21 tandem repeats in S.przewalskii and S.bulleyana,respectively.A synteny comparison of the Salvia spp.cp genomes showed a high degree of sequence similarity in the coding regions and a relatively high divergence of the intergenic spacers.Pairwise alignment and single-nucleotide polymorphism(SNP)analyses found some candidate fragments to identify Salvia spp.,such as the intergenic region of the trnV–ndhC,trnQ–rps16,atpI–atpH,psbA–ycf3,ycf1,rpoC2,ndhF,matK,rpoB,rpoA,and accD genes.All of the results—including the repeat sequences and SNP sites,the inverted repeat(IR)region border,and the phylogenetic analysis—showed that S.przewalskii and S.bulleyana are extremely similar from a genetic standpoint.The cp genome sequences of the two Salvia spp.reported here will pave the way for breeding,species identification,phylogenetic evolution,and cp genetic engineering studies of Salvia medicinal plants.

Anti-inflammatory Effect of Wumen Zhike Gancao Decoction on Rats with Lumbar Disc Herniation Associated with Lipid Metabolic Disorder

[Objectives] To study the anti-inflammatory effect of Wumen Zhike Gancao Decoction (ZKGC) on rats with lumbar disc herniation (LDH) associated with lipid metabolic disorder.[Methods] A rat model of LDH was established by implantation of the autologous nucleus pulposus from the coccygeal vertebra of each rat tail, and histopathology, immunohistochemistry and biochemistry assays were employed to evaluate the treatment effects of ZKGC. In addition, the metabolic characteristics of LDH and ZKGC treatment were investigated with a liquid-chromatography with time-of-flight mass spectrometer (LC/Q-TOF-MS)-based metabolomics study. Nucleus pulpous tissues from rat models were collected and analyzed by metabolomics.[Results] By metabolism network analysis, lipid metabolism was up-regulated in LDH rat models and the treatment with ZKGC significantly reversed the abnormal up-regulated lipid metabolism. Meanwhile, the treatment of ZKGC also regulated the markers of neuron autophagy and inflammatory response in serum.[Conclusions] These results indicated that a complex mechanism, including abnormal lipid metabolism, associates with the progress of LDH, and multiple pathways might be involved in ZKGC s therapeutic effects on LDH.

Allele-aware chromosome-level genome assembly of Artemisia annua reveals the correlation between ADS expansion and artemisinin yield

Artemisia annua is the major natural source of artemisinin,an anti-malarial medicine commonly used worldwide.Here,we present chromosome-level haploid maps for two A.annua strains with different artemisinin contents to explore the relationships between genomic organization and artemisinin production.High-fidelity sequencing,optical mapping,and chromatin conformation capture sequencing were used to assemble the heterogeneous and repetitive genome and resolve the haplotypes of A.annua.Approximately 5o,ooo genes were annotated for each haplotype genome,and a triplication event that occurred approximately 58.12million years ago was examined for the first time in this species.A total of 3,903,467-5,193,414 variants(SNPs,indels,and structural variants)were identified in the 1.5-Gb genome during pairwise comparison between haplotypes,consistent with the high heterozygosity of this species.Genomic analyses revealed a correlation between artemisinin concents and the copy number of amorpha-4,11-dienes ynthasegenes.This correlation was further confirmed by resequencing of 36A.annua samples with varied artemisinin contents.Circular consensus sequencing of transcripts facilitated the detection of paralog expression.Collectively,our study provides chromosome-level allele-aware genome assemblies for two A.annua strains and new insights into the biosynthesis of artemisinin and its regulation,which will contribute to conquering malaria worldwide.

Herbgenomics: A stepping stone for research into herbal medicine

From the prehistoric era until the publishing of the Compendium of Materia Medica and the first scientific Nobel Prize in the Chinese mainland for Tu's discovery on anti-malarial tablets,each milestone and stepping stone in the developmental history of herbal medicine involved intrepid exploration,bold hypothesis formulation,and cautious verification.After thousands of years of discovery and development,herbal research has entered a new era—the era of herbgenomics.Herbgenomics combines herbal and genomic research,bridging the gap between traditional herbal medicine and cutting-edge omics studies.Therefore,it provides a general picture of the genetic background of traditional herbs,enabling researchers to investigate the mechanisms underlying the prevention and treatment of human diseases from an omics perspective.

Disclosure of government financial information and the cost of local government's debt financing——Empirical evidence from provincial investment bonds for urban construction

China's slowing economic growth and rapid urbanization have made local government debt financing a significant issue.This study uses a sample of China's provincial government data for the 2006–2012 period to examine the effect of the disclosure of financial information by local governments on their debt financing costs.The results show that financial information disclosure is conducive to public supervision and enhances government credibility,leading to a decrease in the cost of debt financing.Furthermore,increased government economic intervention increases the strength of the association between financial information disclosure and the cost of debt financing.Increased government audit prevention function weakens the strength of the association between financial information disclosure and the cost of debt financing.

Construction of n-TiO_(2)/p-Ag_(2)O Junction on Carbon Fiber Cloth with Vis-NIR Photoresponse as a Filter-Membrane-Shaped Photocatalyst

The development of effective and reusable photocatalysts with broad-spectra activity has attracted attention.Herein,we have constructed n-TiO_(2)/p-Ag_(2)O junction on carbon fiber(CF)cloth as an efficient and recyclable photocatalyst.With CF cloth as the substrate,TiO_(2) nanorods(length:1-2μm)are prepared by a hydrothermal process,and the in-situ growth of Ag_(2)O nanoparticles(10-20 nm)is then realized by chemical bath deposition route.The flexible CF/TiO_(2)/Ag_(2)O cloth(area:4×4 cm^(2))shows a broad and strong photo-absorption(200-1000 nm).Under the illumination of visible-light(λ>400 nm),CF/TiO_(2)/Ag_(2)O cloth can efficiently eliminate 99.2%rhodamine B(RhB),99.4%acid orange 7(AO7),87.6%bisphenol A(BPA),and 89.5%hexavalent chromium(Cr^(6+))in 100 min,superior to CF/Ag_(2)O cloth(83.5%RhB,60.0%AO7,31.2%BPA and 41.8%Cr^(6+)).In particular,under the NIR-light illumination(980 nm laser),CF/TiO_(2)/Ag_(2)O cloth can remove 70.9%AO7 and 60.0%Cr^(6+) in 100 min,which are significantly higher than those by CF/Ag_(2)O cloth(19.8%AO7 and 18.9%Cr^(6+)).In addition,CF/TiO_(2)/Ag_(2)O cloth(diameter:10 cm),as a filter-membrane,can effectively wipe off 94.4%flowing RhB solution(rate:~1 L h^(−1))at 6th filtering/degrading grade.Thus,CF/TiO_(2)/Ag_(2)O cloth can be used as a Vis-NIR-responded filter-membrane-shaped photocatalyst with high-efficiency for purifying wastewater.
