Objective:To observe the clinical efficacy of continuous theta burst stimulation in the treatment of post-stroke aphasia (PSA).Methods:Forty-six patients with post-stroke aphasia were randomly divided into an observation group and a control group, with 23 cases in each group. In addition to conventional rehabilitation and speech-language therapy, the observation group received daily theta burst stimulation (cTBS) targeting the contralesional inferior frontal gyrus, the superior temporal gyrus, and the superior frontal gyrus. The control group received sham stimulation over the same areas. The treatment was 5 days per week for 3 weeks. Before and after the treatment, both groups were evaluated using the China Rehabilitation Research Center′s aphasia examination method (CRRCAE), the Boston diagnostic aphasia examination (BDAE), the brief mental scale (MMSE), and the Stroke Aphasia Quality of Life scale (SAQOL-39).Results:After the treatment, intra-group comparison showed significantly greater improvements among the observation group in terms of their average CRRCAE listening comprehension (112.74±8.935), repetition (115.74±16.015), speaking (99.91±6.273), oral reading (98.22±14.087), and reading (86.57±8.101) sub-scores and their average BDAE [3.00 (3.00, 4.00)], MMSE [21.00 (20.00, 24.00)] and SAQOL-39 (112.96±21.995) scores.Conclusions:Continuous theta burst transcranial magnetic stimulation can effectively improve the speech, cognition and life quality of persons with post-stroke aphasia. This therapy is worthy of clinical application and promotion.

Objective:To observe the effect of combining low-frequency transcranial magnetic stimulation (rTMS) with melodic intonation therapy (MIT) in the treatment of aphasia soon after a stroke.Methods:Sixty survivors of a recent stroke with aphasia were randomly divided into a control group, an MIT group and an observation group, each of 20. All received conventional rehabilitation therapy, but for 4 weeks the MIT group was additionally given MIT while the observation group received MIT plus 1Hz rTMS applied over the right inferior frontal gyrus and the posterior superior temporal gyrus. The intensity was 80% of the resting motor threshold. Before and after the treatment, language function and communication ability were evaluated using the Chinese version of the Western Aphasia Battery (WAB) and Communicative Activities of Daily Living (CADL) scale.Results:Significant improvements in the WAB and CADL scores and aphasia quotient (AQ) were observed in both the MIT group and the observation group after the treatment compared to their pre-treatment levels, but the observation group demonstrated significantly higher scores than the other two groups on all three assessments. The MIT group′s average scores were superior to those of the control group.Conclusions:Applying rTMS and MIT in combination significantly improves the speech and the daily communication abilities of aphasics early post-stroke, reducing the severity of their aphasia. The therapy exhibits considerable promise for clinical implementation.

Objective:To compare the effect of a 3D-printed ankle and foot orthosis (AFO) with that of a traditional AFO on the recovery of walking function after a stroke.Methods:Thirty-four hemiplegic stroke survivors were randomly divided into an observation group and a control group, each of 17. Both groups were taught good limb placement and given joint mobility, standing and walking training for 4 weeks wearing either a 3D-printed or a conventional AFO. Walking speed, walking endurance, and dynamic balance were evaluated before and after the experiment using the 10-metre walk test (10MWT), the 6-minute walk test (6MWT), and the timed up and go test (TUGT). Integrated electromyography (iEMG) was also performed on each subject′s bilateral rectus femoris, anterior tibialis, and gastrocnemius muscles during walking, and their healthy and affected side iEMG results were compared to assess the activation of the affected lower limb muscles.Results:After treatment, the 10MWT, 6MWT, and TUGT results of both groups had improved significantly, but the observation group′s average results were then significantly better than those in the control group. The iEMG disparities between the healthy and affected sides had also decreased significantly, but on average the disparities in the observation group were significantly smaller than in the control group.Conclusion:Both types of AFO can effectively improve the walking speed, walking endurance, and dynamic balance of hemiplegic stroke survivors and promote muscle activation in the affected lower limb. A 3D-printed AFO is relatively more effective.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Drug metabolism and pharmacokinetics (DMPK) is an important branch of pharmaceutical sciences. The nature of ADME (absorption, distribution, metabolism, excretion) and PK (pharmacokinetics) inquiries during drug discovery and development has evolved in recent years from being largely descriptive to seeking a more quantitative and mechanistic understanding of the fate of drug candidates in biological systems. Tremendous progress has been made in the past decade, not only in the characterization of physiochemical properties of drugs that influence their ADME, target organ exposure, and toxicity, but also in the identification of design principles that can minimize drug-drug interaction (DDI) potentials and reduce the attritions. The importance of membrane transporters in drug disposition, efficacy, and safety, as well as the interplay with metabolic processes, has been increasingly recognized. Dramatic increases in investments on new modalities beyond traditional small and large molecule drugs, such as peptides, oligonucleotides, and antibody-drug conjugates, necessitated further innovations in bioanalytical and experimental tools for the characterization of their ADME properties. In this review, we highlight some of the most notable advances in the last decade, and provide future perspectives on potential major breakthroughs and innovations in the translation of DMPK science in various stages of drug discovery and development.

Objective:To validate the physical activity model for the elderly in nursing homes based on the self-determination theory (SDT) under the Chinese scenario and provide a theoretical basis for future interventions by clarifying the relationship between autonomy support, basic psychological needs, motivation and physical activity in the elderly in nursing homes.Methods:Totally 204 senior citizens from 6 nursing homes in Shenyang City were selected by convenient sampling from March 7 to 13, 2018. The self-made general information questionnaire, Perceived Autonomy Support (PAS) , Psychological Need Satisfaction in Exercise Scale (PNSE) , Revised Behavioral Regulation in Exercise Questionnaire (BREQ-2) and pedometers were used to collected their basic information, autonomy support, psychological satisfaction in exercise, motivation and physical activity. The statistical method of structural equation model was employed to validate the model.Results:The coefficient of 14 paths in the model was significant [χ 2=44.81, degree of freedom ( df) =31, χ 2/ df=1.45, comparative fit index ( CFI) =0.99, root-mean-square error of approximation ( RMSEA) =0.05, standardized root-mean-square residual ( SRMR) =0.03], showing the model simulation was sound. Autonomy support could predict the level of physical activity through the complete mediation of basic psychological needs and motivation. The positive effect of autonomy support on basic psychological needs was 0.96, and the predictive power of the three basic psychological needs for motivation was attribution (0.93) , autonomy (0.88) , and competence (0.81) from high to low. The positive effect of basic psychological needs on autonomous motivation was 0.82, and their negative effect on controlled motivation and amotivation was -0.94 and -0.65, respectively. The positive effect of autonomous motivation on physical activity was 0.64. The negative effect of controlled motivation on physical activity was -0.22, and the negative effect of amotivation on physical activity was -0.19. Conclusions:As a model for understanding the generation and development process of physical activity motivation, SDT is universal and applicable to the elderly population in the context of Chinese culture.
