ObjectiveTo investigate the optimal ratio of goat horn replacing antelope horn in Fufang Lingjiao Jiangya pills and the blood pressure-lowering mechanism of this medicine. MethodsThe blood pressure-lowering efficacy of Fufang Lingjiao Jiangya pills with varying proportions of goat horn replacing antelope horn was evaluated on spontaneous hypertensive rats （SHR）. In this experiment， 50 SHR rats were randomly grouped as follows： model （n=8）， captopril （0.01 g·kg^-1） （n=6）， low-dose blank Fufang Lingjiao Jiangya pills （0.342 g·kg^-1） （n=6）， high-dose blank Fufang Lingjiao Jiangya pills （0.684 g·kg^-1） （n=6）， low-dose antelope horn-containing Fufang Lingjiao Jiangya pills （0.378 g·kg^-1） （n=6）， high-dose antelope horn-containing Fufang Lingjiao Jiangya pills （0.756 g·kg^-1） （n=6）， low-dose goat horn-containing Fufang Lingjiao Jiangya pills （0.378 g·kg^-1） （n=6）， and high-dose goat horn-containing Fufang Lingjiao Jiangya pills （0.756 g·kg^-1） （n=6）. Additionally， 8 WKY rats were used as the normal group. Drugs were administered by gavage for 4 weeks while an equal volume of distilled water was administered for the normal and model groups. Blood pressure was measured before administration， 3 h post administration， and biweekly thereafter. In the experiment for Fufang Lingjiao Jiangya pills with goat horn replacing antelope horn in different proportions， 48 SHR rats were randomly grouped as follows： model， blank Fufang Lingjiao Jiangya pills （0.684 g·kg^-1）， antelope horn-containing Fufang Lingjiao Jiangya pills （0.756 g·kg^-1）， 2× goat horn-containing Fufang Lingjiao Jiangya pills （0.824 g·kg^-1）， 4× goat horn Fufang Lingjiao Jiangya pills （0.969 g·kg^-1）， and 6× goat horn Fufang Lingjiao Jiangya pills （1.112 g·kg^-1）. The normal group included 8 WKY rats， and the normal group and model group received an equal volume of distilled water. The treatment lasted for 2 weeks， and blood pressure was recorded at various time points （pre-administration， 3 h post administration， and on days 4， 7， 10， and 14 of administration）. Serum levels of angiotensin-converting enzyme （ACE）， angiotensin Ⅱ（Ang Ⅱ）， renin， and interleukin-6 （IL-6） were measured by enzyme-linked immunosorbent assay. Histopathological changes in the heart， kidney， and thoracic aorta were observed by hematoxylin-eosin staining. The protein levels of ACE2， angiotensin Ⅱ type 1 receptor （AT1R）， and angiotensinogen （AGT） in the kidney tissue were determined by Western blot， while the expression of nuclear factor （NF）-κB p65 and Toll-like receptor 4 （TLR4） in the thoracic aorta tissue was assessed by immunohistochemistry. ResultsCompared with the model group， all treatment groups showed lowered blood pressure （P<0.05， P<0.01）， and the 6× goat horn-containing Fufang Lingjiao Jiangya pills group showed consistent blood pressure-lowering effect with the antelope horn-containing Fufang Lingjiao Jiangya pills group. Compared with the normal group， the model group showed elevated serum levels of ACE， Ang Ⅱ， renin， and IL-6， while the elevations were declined in the Fufang Lingjiao Jiangya pills groups （P<0.05， P<0.01）. Pathological changes in the heart， kidney， and thoracic aorta were alleviated in all the treatment groups， with the 6× goat horn- and antelope horn-containing Fufang Lingjiao Jiangya pills groups exhibited the best effect. Western blot and immunohistochemistry results showed that all the treatment groups exhibited down-regulated protein levels of AT1R， AGT， NF-κB p65， and TLR4 and up-regulated protein levels of ACE2 （P<0.05， P<0.01） compared with model group， with the 6×goat horn- and antelope horn-containing Fufang Lingjiao Jiangya pills groups showcasing the best effect. ConclusionReplacing antelope horn with 6×goat horn in Fufang Lingjiao Jiangya pills can achieve consistent blood pressure-lowering effect with the original prescription. The prescription may exert the effect by inhibiting the renin-angiotensin-aldosterone system （RAAS） and TLR4/NF-κB signaling pathways.

Peptide receptor radionuclide therapy (PRRT) with radiolabeled SSTR2 agonists is a treatment option that is highly effective in controlling metastatic and progressive neuroendocrine tumors (NETs). Previous studies have shown that an SSTR2 agonist combined with albumin binding moiety Evans blue (denoted as ¹⁷⁷Lu-EB-TATE) is characterized by a higher tumor uptake and residence time in preclinical models and in patients with metastatic NETs. This study aimed to enhance the in vivo stability, pharmacokinetics, and pharmacodynamics of ¹⁷⁷Lu-EB-TATE by replacing the maleimide-thiol group with a polyethylene glycol chain, resulting in a novel EB conjugated SSTR2-targeting radiopharmaceutical, ¹⁷⁷Lu-LNC1010, for PRRT. In preclinical studies, ¹⁷⁷Lu-LNC1010 exhibited good stability and SSTR2-binding affinity in AR42J tumor cells and enhanced uptake and prolonged retention in AR42J tumor xenografts. Thereafter, we presented the first-in-human dose escalation study of ¹⁷⁷Lu-LNC1010 in patients with advanced/metastatic NETs. ¹⁷⁷Lu-LNC1010 was well-tolerated by all patients, with minor adverse effects, and exhibited significant uptake and prolonged retention in tumor lesions, with higher tumor radiation doses than those of ¹⁷⁷Lu-EB-TATE. Preliminary PRRT efficacy results showed an 83% disease control rate and a 42% overall response rate after two ¹⁷⁷Lu-LNC1010 treatment cycles. These encouraging findings warrant further investigations through multicenter, prospective, and randomized controlled trials.

Objective To explore the effects of single-session table tennis exercise with different intensities on working memory and the associated cognitive neural processing mechanisms in college students with depressive symptoms by using event-related potential(ERP)technology.Methods A convenience sampling approach was employed to recruit 100 college students with depressive symptoms from a university.Participants were randomly assigned at a 1∶1∶1∶1 ratio to low-intensity exercise group,moderate-intensity exercise group,high-intensity exercise group,or control group.The exercise groups participated in a single 30-min table tennis intervention at intensities corresponding to 57%-64%of maximum heart rate(HRmax)and rate of perceived exertion(RPE)scores ranging from 9-11,65%-75%HRmax and RPE scores 12-13,and 76%-95%HRmax and RPE scores of 14-17(5-min warm-up,20-min monitored exercise,5-min cool-down).The control group did not receive any exercise intervention.Pre-and post-intervention assessments of verbal working memory(VWM)and spatial working memory(SWM)were performed,alongside the recording of ERP components,including the amplitude and latency of N2 and P3,during the tasks.Results A total of 91 participants(20 in the low-intensity exercise group,25 in the moderate-intensity exercise group,23 in the high-intensity exercise group,and 23 in the control group)were enrolled for analysis.In the VWM task,the main effect of time on accuracy was found to be significant(F(1,89)=5.942,P=0.017,partial η2=0.064).Post-intervention,accuracy was significantly improved in the moderate-intensity and high-intensity exercise groups(change=0.027,95%confidence interval[CI]0.001-0.053,P=0.037;change=0.029,95%CI 0.002-0.055,P=0.040).The main effect of time on reaction time was also significant(F(1,89)=7.244,P=0.009,partial η2=0.077).The interaction between group and time was also significant(F(3,87)=2.844,P=0.042,partial η2=0.089).After the intervention,the reaction time was reduced in the low-intensity and moderate-intensity exercise groups(change=-0.095,95%CI-0.183--0.007,P=0.035;change=-0.079,95%CI-0.158-0,P=0.049).The interaction between time and electrode location in the P3 latency in ERP components was significant(F(3,87)=5.785,P＜0.001,partial η2=0.062),while the interactions for other ERP measures were not significant(all P＞0.05).In the SWM task,the main effect of time on accuracy was significant(F(1,89)=5.092,P=0.027,partial η2=0.055),while the interaction between group and time was not significant(F(3,87)=0.799,P=0.498,partial η2=0.027).After the intervention,accuracy was improved in the moderate-intensity exercise group(change=0.019,95%CI 0-0.037,P=0.046).The main effect of time on reaction time was significant(F(1,89)=14.322,P＜0.001,partial η2=0.141).The interaction between group and time was not significant(F(3,87)=1.521,P=0.215,partial η2=0.050).After the intervention,reaction time was shortened in the moderate-intensity and high-intensity exercise groups(change=-0.082,95%CI-0.136--0.027,P=0.004;change=-0.075,95%CI-0.131--0.018,P=0.029).The interaction between time and electrode location in the P3 amplitude in ERP components was significant(F(3,87)=5.475,P=0.001,partial η2=0.059),while the interactions for other ERP measures were not significant(all P＞0.05).Conclusion Single-session table tennis exercise with different intensities has a positive effect on working memory in college students with depressive symptoms.Moderate-to high-intensity exercise can enhance VWM accuracy,while low-to moderate-intensity exercise can reduce VWM reaction time.Furthermore,moderate-intensity exercise can improve SWM accuracy,and moderate-to high-intensity exercise can shorten SWM reaction time.Additionally,high-intensity exercise can lead to greater activation of ERP components.

Ever since interferon-β was introduced into China more than 20 years ago and used in the disease-modifying therapies (DMT) of multiple sclerosis (MS) patients, the Chinese translations of DMT used in China are quite puzzling, even clinicians are also difficult to understand the meaning of DMT. The authors searched and traced the origins of current DMT translations, which may be mainly due to the fact that the word "modifying" in Chinese contains two meanings: correction and alleviation, obviously currently used names prefer to correct, while the exact meaning of DMT should be to alleviate disease. Considering that inaccurate translation is widely used in domestic academic conferences and academic journals, it is easy to cause misunderstanding and ambiguity. The authors believe that the meaning of DMT should be correctly and deeply understood in the specific context, and the original meaning of alleviating disease should be returned, which is also in line with the two endpoints of immunomodulatory therapy for MS and optic neuromyelitis spectrum disease, the primary endpoint being to reduce the annual recurrence rate of the diseases, the secondary one being to slow the progression of disease disability.

Objective:To establish a rapid pipeline for whole genome sequencing of Chikungunya virus (CHIKV) by combining imbricated multiplex-PCR amplification and Illumina high-throughput sequencing platform.Methods:The primary reference sequences of CHIKV were downloaded from the National Center for Biotechnology Information (NCBI) database, covering all genotypes of CHIKV. After multiple alignments using the Mafft software and phylogenetic analysis, the 20 CHIKV references were selected for primer design. The Primal Scheme tool and Geneious Prime software were used to design, evaluate and optimize the primer panel. Finally, seven CHIKV-positive samples were involved in the validation of the primer panel.Results:All the amplicons of the designed panel were generated successfully. The consensuses generated from the mapping results could cover 100.00% of the coding region of the CHIKV genome when the Ct-value of the sample was less than 33, as the percentage would decrease to 99.38% when the Ct-value reached 35. The mapping percentage could be increased by 5.70%-25.43% when using the stepwise correction mapping strategy.Conclusion:The multiplex-PCR amplification method for CHIKV whole genome sequencing is relatively simple and convenient, which only requires two tubes of PCR amplification and performs well on CHIKV-positive clinical samples with different concentration levels of virus.

Objective To observe the change in the prevalence of post-traumatic stress disorder(PTSD)1 year after trauma exposure and analyze the risk factors of PTSD 1 year after trauma exposure.Methods Convenience sampling was conducted at the initial outbreak of the coronavirus disease 2019 epidemic and 1 year later,respectively.Participants participated in the anonymous online survey.The survey consisted of 2 self-completed questionnaires:1 collected personal information(gender,age,education level,occupation)and subjective sleep quality;the other is the PTSD checklist(PCL-5)from the Diagnostic and Statistical Manual of Mental Disorders,5th edition.Valid questionnaires of 2 091 and 2 092 were respectively retrieved at the initial stage of trauma exposure and 1 year later.Results The prevalence of PTSD at the initial stage of trauma exposure was 5.3％(111/2 091)and 1 year after trauma exposure was 19.1％(399/2 092).Multiple linear regression analysis showed that age(P＜0.01),gender(P＜0.01),and subjective sleep quality(P＜0.01)were risk factors related to PTSD.Conclusions One year after trauma exposure,the prevalence of PTSD increases.Psychological intervention measures should be given at the early stage of trauma exposure,and special attention should be paid to young individuals,women,and those with sleep disorders.

Objective To explore the relationship between basic motor skills and social interaction ability in school-age children with moderate autism,and the mediating role of executive function and the realization path.Methods A cross-sectional design was used to investigate 117 school-age children with autism from Sep.to Dec.2020.The level of basic motor skills was assessed by the test of gross motor development(TGMD),the impairment of executive function was assessed by the behavior rating inventory of executive function(BRIEF),and the social disorder was assessed by the social responsive scale-second edition(SRS-2).Pearson correlation analysis was used to explore the interrelationship,and structural equation modeling was applied to explore the path relationship.Results There was a significant negative correlation between the level of basic motor skills and SRS-2 scores(r=-0.312,P＜0.001).There were significant negative correlations between the level of basic motor skills and the BRIEF scores of inhibition(r=-0.336,P＜0.001),switching(r=-0.325,P＜0.001),affective control(r=-0.338,P＜0.001),task initiation(r=-0.240,P=0.009),working memory(r=-0.278,P=0.002),and planning(r=-0.224,P=0.015).The SRS-2 score was positively correlated with the BRIEF scores of inhibition(r=0.378,P＜0.001),switching(r=0.299,P=0.001),affective control(r=0.417,P＜0.001),task initiation(r=0.246,P=0.007),working memory(r=0.409,P＜0.001),and monitoring(r=0.258,P=0.005).Executive function played a complete intermediary role between basic motor skills and social interaction ability(B=-1.912,95％confidence interval:-3.116 to-1.069).Conclusion In school-age children with moderate autism,executive function and social interaction ability change positively with the level of basic motor skills.Basic motor skills can affect social interaction ability through the mediating role of executive function,and inhibition and affective control are important pathways to achieve this.

Objective:To explore the suitable prostate cancer screening mode under the medical community for primary hospitals.Methods:From April 2021 to April 2022, a total of 16007 male population ≥50 years from 9 branches of the medical community of the second hospital of Yinzhou participated in this study. They were divided into four groups according to age with group 1 of 50-59 years old, group 2 of 60-69 years old, group 3 of 70-79 years old, and group 4 of 80 years old and above. Serum tPSA was added to the routine physical examination, and the screening positive patients were referred to the referral hospital for further diagnosis and treatment under the mode of medical community. We proposed multi-parametric MRI (mpMRI) for those with serum PSA ≥4 ng/ml and suspicious lesions should be scored according to PI-RADS V2. The ultrasound-guided transperineal targeted prostate biopsy was performed for those with PI-RADS ≥3 and those with PI-RADS < 3 but tPSA ≥10 ng/ml. The tPSA follow-up examinations were performed every 6 months for tPSA < 10 ng/ml and PI-RADS < 3 points and once a year for tPSA < 4 ng/ml.Results:Among the 16 007 male population ≥50 years, 2 007(12.54%) were found serum PSA ≥4 ng/ml, and 634(31.59%)were referred to the referral hospital through the medical community system. Combining tPSA and mpMRI, 271 patients underwent ultrasound-guided transperineal targeted prostate biopsy. Among them, 162 were finally diagnosed with PCa, with a biopsy positive rate of 59.78%. The detection rate of PCa in all the subjects was 1.01%. According to the pathological grade, 5(3.08%) were in ISUP group 1, 95(58.64%) in ISUP group 2-3, and 62(38.27%) in ISUP group 4-5. There were 102(62.96%), 39(24.07%) and 21(12.96%) with localized, locally advanced or metastatic PCa, respectively. The levels of tPSA in the four groups were (1.13±1.44)ng/ml, (1.77±3.45)ng/ml, (3.27±17.58)ng/ml, and (4.26±11.48)ng/ml, respectively, with statistically significant differences ( P<0.01). The positive number of biopsy in each group was 1 case(0.06%), 56 cases(0.79%), 81 cases(1.36%) and 24 cases(1.82%) respectively, with statistically significant differences ( P<0.01). The number of ISUP 4-5 grades in each group was 0, 17(30.35%), 29(35.80%), and 16(66.67%) respectively, with statistically significant differences ( P<0.01). Conclusions:Based on the medical community system, according to the tPSA screening results of the primary hospitals, it is feasible and effective to refer suspicious patients to the referral hospitals for mpMRI examination, and screen prostate cancer by ultrasound-guided transperineal prostate fusion biopsy.
