Objective Feasibility application of microelectrode recording(MER)during sub thalamic nucleus deep brain stimulation(STN-DBS)implantation under desflurane general anesthesia(GA)in patients with Par-kinson's disease(PD).Methods A prospective cohort of 20 PD patients undergoing STN-DBS under desflurane general anesthesia were enrolled.Intraoperative MER quality,pos-operative acute pain,cognitive function,anxi-ety/depression status,quality of life,and clinical efficacy of DBS were evaluated.Results Among the patients,14 were male with average PD duration of(8.1±3.6)years.Hoehn-Yahr staging averaged 2.8±0.5 in"on"state and 2.3±0.5 in"off"state.The mean DBS surgery duration was 87.4 minutes.Highly normalized root-mean-square(NRMS)signals were successfully recorded in all cases,with remedial measures applied in 4 pa-tients to achieve satisfactory MER signals.Post-operative Visual Analogue Scale(VAS)pain scores on days 1,2,and 3 were 3.7±2.2,2.8±1.6,and 1.8±2.0,respectively.Montreal Cognitive Assessment(MoCA)scores showed no statistical difference during hospitalization as compared to pre-operative values,but significantly de-creased at 6-month follow-up(24.3±4.1 vs.21.5±3.5,P＜0.05).All patients demonstrated significant reduc-tion in Hamilton Anxiety Scale(HAMA),Hamilton Depression Rating Scale(HAMD),and Parkinson's disease Questionnaire-39(PDQ-39)scores at 6-month follow-up.The unified Parkinson's disease rating scale(UPDRS-Ⅲ)improvement rates were 51.4%±39.2%(medication-on)and 61.6%±26.8%(medication-off)respectively with Levodopa Equivalent Daily Dose(LEDD)improvement rate of 48.6%±23.0%.Conclusions Desflurane general anesthesia is safe and feasible for electrods implantation in STN-DBS of PD patients,without interfering with intra-operative MER or postoperative outcomes.

ObjectiveTo evaluate the quality of Lygodium japonicum (Thunb.) Sw. (L. japonicum, Hai Jin Sha) by comparing its components without stewed (W) and stewed (S) using ultra-high-performance liquid chromatography (UHPLC) and chemometric analysis. Additionally, network pharmacology was employed to investigate the possible mechanisms of action of L. japonicum in the urinary calculi (UC) treatment.MethodsA fingerprinting method was established to identify components through UHPLC-tandem mass spectrometry. Chemometric techniques were used to compare the L. japonicum extraction methods. Furthermore, various network pharmacological approaches were used to identify and analyze the potential targets of the identified components in relation to UC.ResultsThe W and S extracts were distributed into two distinct clusters. Significant differences in the levels of protocatechuic aldehyde, caffeic acid, and p-coumaric acid were observed between S and W. Network pharmacology analysis revealed that the primary targets of L. japonicum in the UC treatment were serum albumin and epidermal growth factor receptors, with potential active components including protocatechuic acid and caffeic acid.ConclusionThis study comprehensively examined the therapeutic components of L. japonicum before and after boiling, shedding light on its potential mechanisms of action in UC treatment. These findings offer valuable insights into the development and utilization of L. japonicum resources.

Objective To investigate the application of intra pelvic pressure(IPP)in ultramicro-channel percutaneous nephrolithotripsy.Methods From January 2022 to January 2023,60 patients with urinary calculi who needed Super mini-PCNL(SMP)in The First Hospital of Jiaxing selected as the study objects.According to random number method,the patients were divided into control group and experimental group,with 30 cases.Both groups were treated with ultra-micro channel percutaneous nephrolithotripsia,while the experimental group was monitored and regulated IPP in real time during the operation,and observed and compared clinical indicators,IPP,fever,urinary protein,renal function,hemoglobin(Hb)and adverse reactions between the two groups.Results Compared with the control group,the hospitalization time of experimental group was shortened and the stone clearance rate was increased(P<0.05).The IPP levels of experimental groups at 6min,12min,24min and 36min were lower than those of control group(P<0.05).The fever of experimental group was lower than that of control group at 2d,3d,4d and 5d after operation(P<0.05).The urinary protein level of experimental group was lower than that of control group at 1d,2d,3d and 4d after operation(P<0.05).Compared with control group,blood urea nitrogen(BUN)and serum creatinine(SCr)levels of experimental group were decreased,and Hb levels were increased(P<0.05).The incidence of adverse reactions in experimental group was lower than that in control group(P<0.05).Conclusion Monitoring and adjusting intrapelvic pressure during super-mini percutaneous nephrolithotomy is beneficial in reducing postoperative fever in patients with urolithiasis,reducing urinary protein expression and kidney function damage,and controlling the occurrence of adverse reactions.It is worth recommending.

OBJECTIVE: To explore the clinical characteristics and molecular genetic mechanism of a fetus with recombinant chromosome 8 (Rec8) syndrome. METHODS: A fetus who was diagnosed with Rec8 syndrome at the Provincial Hospital Affiliated to Shandong First Medical University on July 20, 2021 due to high risk for sex chromosomal aneuploidy indicated by non-invasive prenatal testing (NIPT) (at 21st gestational week) was selected as the study subject. Clinical data of the fetus was collected. G-banded karyotyping and chromosomal microarray analysis (CMA) were carried out on the amniotic fluid sample. Peripheral blood samples of the couple were also subjected to G banded karyotyping analysis. RESULTS: Prenatal ultrasonography at 23rd gestational week revealed hypertelorism, thick lips, renal pelvis separation, intrahepatic echogenic foci, and ventricular septal defect. The karyotype of amniotic fluid was 46,XX,rec(8)(qter→q22.3::p23.1→qter), and CMA was arr[GRCh37]8p23.3p23.1(158049_6793322)×1, 8q22.3q24.3(101712402_146295771)×3. The karyotype of the pregnant woman was 46,XX,inv(8)(p23.1q22.3), whilst that of her husband was normal. CONCLUSION The Rec8 syndrome in the fetus may be attributed to the pericentric inversion of chromosome 8 in its mother. Molecular testing revealed that the breakpoints of this Rec8 have differed from previously reported ones.

The promise of regeneration therapy for restoration of damaged myocardium after cardiac ischemic injury relies on targeted delivery of proliferative molecules into cardiomyocytes whose healing benefits are still limited owing to severe immune microenvironment due to local high concentration of proinflammatory cytokines. Optimal therapeutic strategies are therefore in urgent need to both modulate local immunity and deliver proliferative molecules. Here, we addressed this unmet need by developing neutrophil-mimic nanoparticles NM@miR, fabricated by coating hybrid neutrophil membranes with artificial lipids onto mesoporous silica nanoparticles (MSNs) loaded with microRNA-10b. The hybrid membrane could endow nanoparticles with strong capacity to migrate into inflammatory sites and neutralize proinflammatory cytokines and increase the delivery efficiency of microRNA-10b into adult mammalian cardiomyocytes (CMs) by fusing with cell membranes and leading to the release of MSNs-miR into cytosol. Upon NM@miR administration, this nanoparticle could home to the injured myocardium, restore the local immunity, and efficiently deliver microRNA-10b to cardiomyocytes, which could reduce the activation of Hippo-YAP pathway mediated by excessive cytokines and exert the best proliferative effect of miR-10b. This combination therapy could finally improve cardiac function and mitigate ventricular remodeling. Consequently, this work offers a combination strategy of immunity modulation and proliferative molecule delivery to boost cardiac regeneration after injury.

Background: Classical swine fever virus (CSFV), the causative agent of classical swine fever (CFS), is a highly contagious disease that poses a serious threat to Chinese pig populations. Objectives: Many provinces of China, such as Shandong, Henan, Hebei, Heilongjiang, and Liaoning provinces, have reported epidemics of CSFV, while the references to the epidemic of CSFV in Yunnan province are rare. This study examined the epidemic characteristics of the CSFV in Yunnan province. Methods: In this study, 326 tissue samples were collected from different regions in Yunnan province from 2015 to 2021. A reverse transcription-polymerase chain reaction (RT-PCR), sequences analysis, and phylogenetic analysis were performed for the pathogenic detection and analysis of these 326 clinical specimens. Results: Approximately 3.37% (11/326) of specimens tested positive for the CSFV by RTPCR, which is lower than that of other regions of China. Sequence analysis of the partial E2 sequences of eleven CSFV strains showed that they shared 89.0–100.0% nucleotide (nt) and 95.0–100.0% amino acid (aa) homology, respectively. Phylogenetic analysis showed that these novel isolates belonged to the subgenotypes 2.1c and 2.1d, with subgenotype 2.1c being predominant. Conclusions The CSFV was sporadic in China’s Yunnan province from 2015 to 2021. Both 2.1c and 2.1d subgenotypes were found in this region, but 2.1c was dominant.

A 75-year-old patient was admitted with "progressive dysuria for more than 2 months" in January 2017. The tPSA level was 498 ng/ml and then diagnosed as metastatic prostate cancer (cT 3bN xM 1). For the resistance of abiraterone, gene mutation was detected during the endocrine therapy. After 5 months of endocrine therapy, the serum tPSA was decreased to a minimum of 12.5 ng/ml. Since July, the serum PSA level gradually rebounded, and the endocrine therapy was altered to androgen deprivation therapy (ADT). The level of tPSA was maintained at 104 ng/ml in October 2017, and ADT was discontinued. After 1 year of discontinuation, the re-examination of PSA was 3 205 ng/ml. As the first-line regimen for mCRPC, abiratone and prednisone combined with goserelin was used. After 5 months of treatment, the level of tPSA still showed progression. The drug resistance of abiraterone was considered, so the treatment was discontinued. Next-generation sequencing technology (NGS) revealed the presence of AR, FGFR3 and RIT1 mutations, while no HRR germline mutation was detected. Docetaxel combined with ADT was performed. It was changed to comprehensive treatment of goserelin + docetaxel in March 2019. During chemotherapy CT images indicated significant reduction of pelvic lymph nodes and left inguinal lymph nodes, while bone metastasis showed stable condition. In April 2020, the chemotherapy was terminated for the lower extremity edema, joint pain and other related discomfort. The level of tPSA was 289 ng/ml after the last chemotherapy. DNA sequencing testing were performed again, and the mutation of AR and AR-V7 was negative. According to the results of genetic testing, the tPSA continued to decrease to 23 ng/ml after 6 months of abiraterone rechallenge, the imagings suggested that no disease progression. After AR mutation turns negative after chemotherapy, patients with refractory CRPC can still obtain a good PSA response such as tumor control and other clinical benefits from abiraterone. Abiraterone rechallenge is probably a new attempt for AR mutant patients with refractory CRPC.

OBJECTIVE：To provide reference for the identification and proces sing end-point determination of raw Morus alba and its processed products （honey-processed M. alba ）. METHODS ：UPLC method was adopted. The determination was performed on Waters BEH Shield RP C 18 column with mobile phase consisted of acetonitrile- 0.1％ phosphoric acid solution （gradient elution ） at the flow rate of 0.30 mL/min. The column temperature was set at 30 ℃. The program wavelengths were set at 280 nm（0-4 min） and 320 nm（4-35 min）. Similarity Evaluation System for Chromatogram Fingerprint of TCM （2012 edition）was used to establish UPLC fingerprint and carry out similarity evaluation of 13 batches of M. alba and honey-processed M. alba . The chromatographic peaks were identified with reference substance fingerprint. The colorimetric value （L，a，b） of 13 batches of M. alba and honey-processed M. alba powder were determined ，and average total colorimetric value （E）was calculated. OPLS-DA and cluster analysis were adopted to analyze the differences in fingerprints and colorimetric values of M. alba before and after processing. At the same time ，the dynamic change rule of fingerprint and colorimetric value of honey-processed M. alba at different processing time points were analyzed to determine the processing end-point. RESULTS ：There were obvious differences in fingerprints before and after processing ，and the similarity of 13 batches of M. alba and honey-processed M. alba were all higher than 0.9. Totally 21 common peaks were calibrated for M. alba ，and 23 common peaks for honey-processed M. alba ；peak 1 and peak 2 were newly produced compounds of honey-processed M. alba . Peak 2，peak 7，peak 14 and peak 19 were identified as 5-hydroxymethylfurfural， mulberry glucoside A ，oxidized resveratrol ，mulberry flavonoids G. Results of OPLS-DA showed that the peak area-sample quantity ratio of peak 1，peak 2，peak 18，peak 20 and the chromaticity values （L，a，b）were the most important factors affecting the difference of raw and processed products of M. alba . When the E ranged 75.84-80.88 as the processing end-point of honey-processed M. alba ，the processing time was determined as 22-34 min. CONCLUSIONS ： The established UPLC fingerprint and colorimetric value determination method can be used to identify the raw and processed products of M. alba as well as determine the processing end-point of honey-processed M. alba .

OBJECTIVE：To establish HP LC ch aracteristic ch romatogram of different medicinal parts of Cirsium japonicum ， and to compare the difference of chemical components in different medicinal parts of C. japonicum according to chemical identification method ，and to provide reference for quality control and evaluation of C. japonicum . METHODS ：Medicinal material （overground part ），leaves，flower，main stem and lateral stem of C. japonicum were determined by HPLC. According to the TCM Chromatographic Fingerprint Similarity Evaluation System （2012A edition ），the chromatograms were matched to generate the HPLC characteristic chromatogram of each medicinal part. The differences of common characteristic peak area were analyzed according to variance analysis of single factor. The chromatographic peaks were identified by comparison of reference substance. Meanwhile，the chemical pattern recognition was performed to research the different medicinal parts of C. japonicum according to principal component analysis （PCA）and cluster analysis. RESULTS ：HPLC characteristic chromatograms of medicinal material ， leaves，flower，main stem and lateral stem from C. japonicum were established respectively ，and 15 common peaks were confirmed for medicinal material ，leaves and flower of C. japonicum ；11 common peaks were confirmed in chromatograms of main stem and lateral stem from C. japonicum （absence of No. 7，9，12，13 peak）. The contents of chemical components were different greatly among different medicinal parts. No. 1，2，3，10，11 peaks were identified as neochlorogenic acid ，chlorogenic acid ， cryptochlorogenic acid ，linarin and pectolinarin. Results of PCA and cluster analysis showed that chemical pattern recognition and clustering of the flower and stem of C. japonicum were distinct and can be clustered into one category respectively. However ，the leaves distribution of C. japonicum was relatively scattered ，so it was difficult to cluster . CONCLUSIONS ：Established HPLC characteristic chromatogram-chemical pattern recognition can reflect the differences of different medicinal parts of C. japonicum integrally， comprehensively and truly ， which has vital significance for origin indentification ， quality control and overall evaluation of C. japonicum .

Currently, there are many studies on the mechanism of antibiotic resistance in Mycobacterium tuberculosis (Mtb), but there are few studies on its regulatory mechanism. Post-translational modifications (PTMs) have been recognized for their important role in controlling cellular dynamics such as metabolism and stress response, but the relationship between PTMs and antibiotic resistance gradually attracted the attention of researchers. Here, we summarize the definition of PTMs, and the mechanisms of antibiotic resistance in M. tuberculosis and discuss how PTMs are involved in antibiotic resistance, in order to provide a new breakthrough for the development of new anti-Ttb drugs.
