Network Meta-analysis was conducted to evaluate the efficacy and safety of different traditional Chinese medicine injections combined with conventional western medicine in treatment of cerebral small vessel disease(CSVD). Computerized searches were conducted in PubMed, Cochrane Library, Web of Science, EMbase, CNKI, Wanfang, VIP, and SinoMed for randomized controlled trial(RCT) published in Chinese or English using traditional Chinese medicine injections to treat CSVD. The search time is from the inception to July 15, 2024. Literature screening and statistical analysis were conducted with NoteExpress 3.0.3, RevMan 5.3.5, and Stata 15.1.6. A total of 45 articles were included, involving 3 717 patients, with 1 944 patients in the treatment group and 1 773 patients in the control group. A total of 15 kinds of traditional Chinese medicine injections were involved. Network Meta-analysis indicated that,(1) in terms of improving clinical total effective rate, the best intervention in SUCRA was Ciwujia Injection + conventional western medicine.(2) In terms of reducing NIHSS scores, the best intervention in SUCRA was Xueshuantong Injection + conventional western medicine.(3) In terms of improving ADL scores, the best intervention in SUCRA was Danshen Injection + conventional western medicine.(4) In terms of improving MMSE scores, the best intervention in SUCRA was Xueshauntong Injection + conventional western medicine.(5) In terms of improving MoCA scores, the best intervention in SUCRA was Salvianolate Injection + conventional western medicine.(6) In terms of reducing plasma viscosity(PV), the best intervention in SUCRA was Danhong Injection + conventional western medicine.(7) In terms of reducing the hematocrit, the best intervention in SUCRA was Xuesaitong Injection + conventional western medicine.(8) In terms of reducing fibrinogen, the best intervention in SUCRA was Xuesaitong Injection + conventional western medicine.(9) In terms of reducing erythrocyte sedimentation rate(ESR), the best intervention in SUCRA was Danshen Injection + conventional western medicine.(10) In terms of reducing total cholesterol(TC), triglycerides(TG), and low-density lipoprotein(LDL), the best intervention in SUCRA was Danshen Injection + conventional western medicine. The radar chart results indicated that the advantage of Salvianolate Injection lies in improving cognitive function, while the advantage of Xueshuantong Injection lies in improving neurological function. The advantage of Xuesaitong Injection lies in improving hemodynamic parameters, and the advantage of Danshen Injection lies in improving behavioral ability, hemodynamics, and blood lipid levels. In terms of safety, there was no significant difference in the incidence of adverse reactions between the traditional Chinese medicine injection treatment group and the conventional western medicine group, and no serious adverse reactions occurred. The results showed that the combination of traditional Chinese medicine injections and conventional western medicine can effectively improve the clinical total effective rate, the neurological and cognitive functions, hemodynamic parameters, and blood lipid levels of patients suffering from CSVD. In addition, more double-blind, multi-center, large-sample RCT is needed to verify these findings and to provide more high-quality evidence on the efficacy and safety of traditional Chinese medicine injections for CSVD.

OBJECTIVE: To explore clinical efficacy of tibial transverse transport (TTT) combined with debridement in treating necrotizing fasciitis of the lower extremities. METHODS: A retrospective analysis was conducted on 31 patients with necrotizing fasciitis of the lower extremities who were treated with TTT from January 2021 to October 2023, including 28 males and 3 females, aged from 44 to 76 years old with an average of (57.58±8.79) years old. In-hospital mortality rate, amputation rate, length of hospital stay, hospitalization cost, number of surgeries, and inflammatory indicators before and after operation (white blood cells, hemoglobin, C-reactive protein, albumin), as well as wound healing and daily living ability were observed and compared. RESULTS: All 31 patients were followed up for 3 to 12 months with an average of (6.61±2.46) months. All patients' wounds healed without recurrence. The wound healing time was (4.96±2.61) months, amputation rate of 31 patients was 3.22% (1/31), in-hospital mortality rate was 0%, the length of hospital stay was (27.10±24.51) days, the hospitalization cost was (107, 300 ± 83, 300) yuan, and the number of surgeries was (3.26±1.93) times. White blood cells, C-reactive protein and albumin before operation were (13.41±5.54) ×10⁹/L, (136.67±73.50) mg·L^-1 and (25.92±5.59) g·L^-11 respectively, and improved to (11.05±3.65) ×10⁹/L, (79.91±51.40) mg·L^-1, and (30.31±4.02) g·L^-1 at 2 weeks after operation, and the differences were statistically significant (P<0.05);there was no statistically significant difference in hemoglobin before and after operation (P>0.05). At the latest follow-up, 16 patients were able to take care of themselves, 12 patients were partially self-sufficient, and 3 patients were completely unable to take care of themselves. CONCLUSION TTT with debridement could achieve satisfactory clinical efficacy in treating necrotizing fasciitis of the lower extremities.

OBJECTIVE: This study aimed to investigate the effect of Astragalus (AST) on osteoporosis (OP) and the downstream mechanisms. METHODS: Human bone marrow-derived mesenchymal stem cells (hBMSCs) were induced to differentiate into osteogenic cells. After transfection with relevant plasmids, cell proliferation, cell cycle progression, and apoptosis were assessed. Alizarin red staining was used to detect calcium nodules in the cells, alkaline phosphatase (ALP) staining was used to detect ALP activity in the cells, and quantitative reverse transcription-polymerase chain reaction and western blotting were used to determine RUNX2 and Osterix expression levels. An OP rat model was established using ovariectomy and micro-computed tomography scanning. Hematoxylin and eosin staining and Masson's trichrome staining were used to evaluate the pathological conditions of bone tissues, while immunohistochemistry was conducted to detect RUNX2 in bone tissues. RESULTS: AST promoted the osteogenic differentiation of BMSCs, reduced miR-181d-5p expression levels, and increased SOX11 expression levels. Restoring miR-181d-5p expression or reducing SOX11 expression levels reversed the effects of AST on the osteogenic differentiation of hBMSCs. miR-181d-5p was found to target SOX11 in hBMSCs. AST improved OP in rats, and miR-181d-5p overexpression or SOX11 inhibition reversed the therapeutic effects of AST on OP in rats. CONCLUSION AST promoted the osteogenic differentiation of hBMSCs and alleviated OP by targeting SOX11 via miR-181d-5p.

Objective To explore the diagnosis and treatment experience of malignant peritoneal mesothelioma by analyzing the clinical characteristics of patients with single center peritoneal mesothelioma.Methods Retrospec-tively analyze the clinical data,including age and treatment regimens,of 99 patients with malignant peritoneal mes-othelioma admitted to Peking Union Medical College Hospital from June 2012 to July 2023.Kaplan-Meier for surviv-al analysis and Logistic and Cox regression were applied to assess the impact of factors like age and treatment regi-mens on survival time.Results The median age of diagnosis for 99 patients with peritoneal mesothelioma was 56 years,of which 82 were pathologically diagnosed.Among them,38 cases(51.4%)underwent tumor cell reduction surgery,and 57 cases(77.0%)underwent systemic or local treatment.The median survival time for all patients was 43 years.The age of diagnosis may affect the prognosis of patients with malignant mesothelioma,and those aged≥65 at the time of diagnosis have a worse prognosis.Conclusions Malignant peritoneal mesothelioma is a rare but invasive malignant tumor with a poor prognosis.There is still a need to develop novo drugs and comprehensive treat-ment strategies.

Retrograde adeno-associated viruses (AAVs) are capable of infecting the axons of projection neurons and serve as a powerful tool for the anatomical and functional characterization of neural networks. However, few retrograde AAV capsids have been shown to offer access to cortical projection neurons across different species and enable the manipulation of neural function in non-human primates (NHPs). Here, we report the development of a novel retrograde AAV capsid, AAV-DJ8R, which efficiently labeled cortical projection neurons after local administration into the striatum of mice and macaques. In addition, intrastriatally injected AAV-DJ8R mediated opsin expression in the mouse motor cortex and induced robust behavioral alterations. Moreover, AAV-DJ8R markedly increased motor cortical neuron firing upon optogenetic light stimulation after viral delivery into the macaque putamen. These data demonstrate the usefulness of AAV-DJ8R as an efficient retrograde tracer for cortical projection neurons in rodents and NHPs and indicate its suitability for use in conducting functional interrogations.

Demyelination of the central nervous system often occurs in neurodegenerative diseases， such as multiple sclerosis （MS）. The myelin sheath， a layer of myelin membrane wrapping the axon， plays a role in the rapid conduction and metabolic coupling of impulses for neurons. The exposure of the axon will lead to axonal degeneratio， and further neuronal degeneration， which is the main cause of dysfunction and even disability in patients with demyelinating neurodegenerative diseases. In addition to the demyelination of mature myelin sheath， remyelination disorder is also one of the major reasons leading to the development of the diseases. The myelin sheath is composed of oligodendrocytes （OLs） derived from oligodendrocyte progenitor cells （OPCs） which are differentiated from neural stem cells （NSCs）. The process of myelin regeneration， i.e.， remyelination， is the differentiation of NSCs into OLs. Recent studies have shown that this process is regulated by a variety of genes. MicroRNAs， as important regulators of neurodegenerative diseases， form a complex regulatory network in the process of myelin regeneration. This review summarizes the main molecular pathways of myelin regeneration and microRNAs involved in this process and classifies the mechanisms and targets. This review is expected to provide a theoretical reference for the future research on the treatment of demyelinating diseases by targeting the regulation of microRNAs.

Objective:To discuss the regulatory effect of physiological tensile stress on the differentiation of chondrocytes,and to clarify the associated signaling pathway mechanism.Methods:The ATDC5 chondrocytes were cultured in vitro and subjected to physiological tensile stress by four-point bending cell mechanical loading device.Initially,the cells were divided into control group and tensile stress group(2 000 μstrain/2 h group),and further divided into different stress magnitudes(1 000,2 000,and 3 000 μstrain)for 2 h,and 2 000 μstrain for different duration time(1,2,and 4 h)groups;the cells without tensile stress were used as control group.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of type Ⅱ collagen(Col-Ⅱ),type Ⅹ collagen(Col-Ⅹ),aggregated proteoglycom(Aggrecan),sex-determining region Y-box protein 9(SOX9),vascular endothelial growth factor(VEGF),proliferating cell nuclear antigen(PCNA),Nel-like molecule tyep 1(Nell-1),Runt-related transcription factor 2(Runx2),Indian hedgehog(Ihh),patched homolog 1(Ptch-1),GLI family zinc finger protein 1(Gli-1),and hedgehog interacting protein 1(Hhip-1)mRNA in the cells in various groups;Western blotting method was used to detect the expression levels of Nell-1,Runx2,and Ihh proteins in the cells in various groups.The ATDC5 cells were divided into control group,cyclopamine group,tensile stress group,and cyclopamine + tensile stress group.RT-qPCR method was used to detect the expression levels of Nell-1,Ihh,Ptch-1,Gli-1,and Hhip-1 mRNA in the cells in various groups;Western blotting method was used to detect the expression levels of Nell-1 and Ihh proteins in the cells in various groups.Results:Compared with control group,the expression levels of Col-Ⅱ,Col-Ⅹ,Aggrecan,SOX9,VEGF,and PCNA mRNA in the cells in 2 000 μstrain/2 h group were significantly increased(P<0.01);after treated with 2 000 μstrain tensile stress for different duration time(1,2,and 4 h)or different tensile stresses(1 000,2 000,and 3 000 μstrain)for 2 h,compared with control group,the expression levels of Runx2 mRNA in the cells in other groups were increased with the prolongation of time or the increasing of tensile stress(P<0.01),and the expression levels of Nell-1,Ihh,Ptch-1,Gli-1,and Hhip-1 mRNA were gradually increased(P<0.01),the expression levels reached the peaking at 2 000 μstrain/2 h,and then decreased but remained significantly higher than that in control group(P<0.01).The Western blotting results showed that the expression levels of Nell-1,Runx2,and Ihh proteins in the cells were consistent with the change trend of mRNA expression levels.After pre-treated with cyclopamine,compared with control group,the expression levels of Ihh,Ptch-1,Gli-1,and Hhip-1 mRNA in the cells in cyclopamine group were significantly decreased(P<0.01),and the expression levels of Ihh,Ptch-1,Gli-1,and Hhip-1 mRNA in the cells in tensile stress and cyclopamine+tensile stress groups were significantly increased(P<0.01);compared with cyclopamine group,the expression levels of Nell-1,Ihh,Ptch-1,Gli-1,and Hhip-1 mRNA in the cells in cyclopamine+tensile stress group were significantly increased(P<0.01);compared with tensile stress group,the expression levels of Ihh,Ptch-1,Gli-1,and Hhip-1 mRNA in the cells in cyclopamine + tensile stress group were significantly decreased(P<0.01).Compared with control group,the expression level of Ihh protein in the cells in cyclopamine group was significantly decreased(P<0.01),but there was no significant difference in expression level of Nell-1 protein in the cells between control group and cyclopamine group(P>0.05),while the expression levels of Nell-1 and Ihh proteins in the cells in tensile stress group and cyclopamine + tensile stress group were significantly increased(P<0.01);compared with cyclopamine group,the expression levels of Nell-1 and Ihh proteins in the cells in tensile stress group and cyclopamine + tensile stress group were significantly increased(P<0.01);compared with tensile stress group,in the expression levels of Nell-1 and Ihh proteins in the cells in cyclopamine + tensile stress group had no significant differences(P>0.05).Conclusion:After stimulated with physiological tensile stress,Nell-1 can activate the Ihh signaling pathway upstream,and regulate the differentiation of the ATDC5 chondrocytes.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Objective To explore the clinical characteristics of patients with alcoholic liver disease(ALD)of various traditional Chinese medicine(TCM)syndrome types.Methods A retrospective analysis was conducted in 129 patients with alcoholic liver disease who met the inclusion and exclusion criteria in Foshan Hospital of Traditional Chinese Medicine from 2018 to 2022.The general data of the patients as well as their TCM syndrome types and clinical information of liver and kidney function,blood lipid,liver transient elastography during the hospital visit were collected.The distribution of TCM syndrome types in ALD patients was analyzed,and the clinical characteristics of the ALD patients with various TCM syndrome types were explored.Results(1)Of the 129 patients,128(99.22%)were male and only one(0.78%)was female,the average age was(48.71±11.50)years old,and the average body mass index(BMI)was(23.82±3.98)kg·m-2.(2)Damp-heat accumulation syndrome was most common syndrome type in ALD patients,with a total of 70 cases(54.26%),and then came liver depression and spleen deficiency syndrome(24 cases,18.60%),internal obstruction of phlegm-damp syndrome(22 cases,17.05%),liver-kidney sufficiency syndrome(7 cases,5.43%),phlegm interweaved with blood stasis syndrome(3 cases,2.33%),and internal accumulation of blood stasis syndrome(3 cases,2.33%).(3)The analysis of clinical characteristics by non-parametric rank sum test showed that there were no statistically significant differences in BMI,alcohol consumption,aspartate aminotransferase(AST),gamma-glutamyltransferase(GGT),total bilirubin(TBIL),alkaline phosphatase(ALP),triglyceride(TG),liver stiffness measurement(LSM),and controlled attenuation parameter(CAP)which reflects the fat content of liver in ALD patients with various TCM syndrome types(P＜0.05 or P＜0.01).The prominent features were as follows:patients with the 4 types of liver depression and spleen deficiency,internal obstruction of phlegm-damp,phlegm interweaved with blood stasis,and internal accumulation of blood stasis had a BMI exceeding the standard(＞24 kg·m-2),whereas patients with damp-heat accumulation syndrome and liver-kidney deficiency syndrome,which accounted for 54.26%of the sample size,had a BMI within the normal range(23.03 kg·m-2 and 21.42 kg·m-2,respectively),and the BMI of these two types differed from that(26.44 kg·m-2)of the internal obstruction of phlegm-damp syndrome(P＜0.01),suggesting that more than half of the ALD patients had the normal BMI;moreover,the patients with internal obstruction of phlegm-damp also had the highest values of serum TG(2.69 mmol/L)and CAP(292 db/m)except for the highest BMI,indicating that patients with internal obstruction of phlegm-damp syndrome had a more serious degree of obesity and hepatic fat infiltration than those with other syndrome types;the levels of AST and GGT,which separately reflect the chronic inflammatory injury of liver and bile duct cell injury,were significantly increased in the patients with damp-heat accumulation syndrome and liver-kidney deficiency syndrome,and the LSM value of these two types of patients was also the highest in all of the syndrome types,the differences being all statistically significant(P＜0.05 or P＜0.01).Conclusion Damp-heat accumulation syndrome is the main TCM syndrome type of ALD patients,the degree of fatty infiltration of the liver and overweight of ALD patients are not corresponded to the severity of illness,and there are some differences in the clinical indicators of ALD patients with various TCM syndrome types.However,with cross reference to the data of the four diagnostic examinations of TCM and the clinical indicators,the accuracy of the TCM diagnosis of ALD is expected to be increased.

Objective:To investigate the potential value of saccade and antisaccade parameters in early identification of Parkinson′s disease (PD) and its motor subtypes.Methods:A total of 111 PD patients [tremor dominant (TD) type in 45, postural instability/gait difficulty (PIGD) type in 54 and indeterminate type in 12)] and 54 healthy controls were recruited from Department of Neurology, Guangdong Provincial People′s Hospital from July 2022 to July 2023. All subjects underwent oculomotor test including visually guided saccades and volitional antisaccades by the Eyeknow-M10-B Eye tracker. For PD patients, TD and PIGD scores were measured using the Movement Disorder Society Unified Parkinson′s Disease Rating Scale (MDS-UPDRS) Part Ⅱ and Part Ⅲ. Oculomotor parameters among TD, PIGD patients and healthy controls were firstly compared. Multiple linear regression analyses were performed to assess the relationship between ocular parameters with differences and TD/PIGD score. Then receiver operating characteristic (ROC) curve analysis was made between PD patients and healthy controls, as well as between PIGD and TD subtypes.Results:Compared to healthy controls, PD patients showed significantly decreased saccadic accuracy [100.0%(90.0%, 100.0%) vs 100.0%(100.0%, 100.0%), U=1 732.500, P<0.001], prolonged latency [252.2(228.5, 300.1) ms vs 227.7(214.2, 241.8) ms, U=1 401.000, P<0.001], minimum duration [233.6(211.2, 278.8) ms vs 211.0(200.0, 222.5) ms, U=1 534.500, P<0.001], average duration [356.6(313.8, 427.8) ms vs 279.4(267.4, 312.9) ms, U=881.000, P<0.001],as well as decreased peak [444.4(335.0, 593.7) °/s vs 526.7(412.6, 696.2) °/s, U=1 971.000, P=0.007] and average velocity [196.3(144.4, 240.5) °/s vs 256.7(226.7, 312.0) °/s, U=1 330.000, P<0.001] in saccades. And in antisaccades, PD patients also showed prolonged latency [432.0(362.9, 599.8) ms vs 352.9(309.8, 407.6) ms, U=1 553.000, P<0.001], minimum duration [333.4(299.8, 377.6) ms vs 290.1(263.9, 332.9) ms, U=1 608.000, P<0.001], average duration [518.2(462.7, 603.5) ms vs 424.2(377.1, 473.5) ms, U=1 181.000, P<0.001], decreased peak [458.5(327.9, 604.3) °/s vs 560.4(440.3, 698.5) °/s, U=1 838.500, P=0.001] and average velocity [186.6(143.1, 228.1) °/s vs 263.2(217.2, 301.5) °/s, U=1 131.000, P<0.001]. There was no statistically significant difference in antisaccadic accuracy [55.0%(15.0%, 80.0%) vs 66.7%(39.4%, 86.9%), U=2 167.500, P=0.053]. Compared with TD subtype, PIGD patients showed significantly decreased antisaccadic peak velocity [416.2(300.3, 534.3) °/s vs 527.1(402.3, 636.4) °/s, U=-26.474, P=0.009]. After adjusting for age, gender and education, antisaccadic peak velocity was negatively correlated with PIGD score in PD patients (β=-0.296, P=0.001), and no correlation with TD score was found. The ROC analysis was performed on combined saccadic and antisaccade metrics between PD patients and healthy controls, with area under the curve (AUC) as 0.918. For antisaccadic peak velocity between PIGD and TD subtypes, the AUC was 0.690. Conclusions:Eye movement metrics have potential value in distinguishing PD patients from healthy controls. The antisaccadic peak velocity is related to the severity of motor symptoms in PIGD patients, which is helpful for distinguishing the motor subtypes of PD patients.
