Traditional Chinese spinal orthopedic manipulation

Traditional Chinese spinal orthopedic manipulation(TCSOM)is an external therapeutic method of traumatology and orthopedics of traditional Chinese medicine to treat trauma and set bone.The doctor exerts his force through thumb or bilateral upper extremities on the spine or acupoints of the patient,applying various manipulatory techniques according to the conditions.Correcting the abnormal position or state of the spine serve as the most important theoretical foundation for TCSOM to treat spinal disorders and spinogenic disorders.This paper presented the definition and function of the TCSOM,with a special focus on how to make a preliminary diagnosis of spinal segments disorders,and the indications of TCSOM in different spinal segments.

Many faces of neuronal activity manipulation in Drosophila

Animals exhibit complex responses to external and internal stimuli.The information is computed by interconnected neurons that express numerous ion channels,which modulate the neuronal membrane potential.How can neuronal activity orchestrate complex motor patterns or allow learning from previous experience?To answer such questions,we need the ability not only to record,but also to modulate neuronal activity in both space(e.g.,neuronal subsets)and time.

An exploration of the origin and flow of the development of traditional Chinese medicine orthopedic and chiropractic massage

Traditional Chinese medicine(TCM)chiropractic massage is a kind of orthopedic therapy that corrects the abnormal anatomical position of bone or joint and corrects the dislocation of joint by manipulation so that the bone is soft and the Qi and blood are reconciled(Qi:The intangible,high-mobility nutritive substance that maintains vital activities).Manipulation treatment is the first of the four major orthopedic diseases.At the same time,TCM chiropractic massage is also an essential part of TCM.TCM orthopedic chiropractic practice originated from the struggle between humanity and nature,sprouted from the Warring States period to the two Han Dynasty,formed in the Sui,Tang,and Song Dynasties,matured in the Ming and Qing Dynasties,and flourished in the modern era.In more than 2,000 years of development,many practical techniques have been produced,which have profoundly influenced the inheritance and development of modern techniques,making the TCM orthopedic chiropractic massage in the contemporary era form the characteristics of“tendon and bone”and“point-line-face combination”.At present,the development of TCM chiropractic massage is facing the great challenges of modern medicine and modern advanced science and technology such as American chiropractic and the limitations of its development.Therefore,in the future,the development direction of Chinese medicine orthopedic chiropractic massage should be“hybrid to treat”.In the face of modern medicine,we should take its essence to its dross,eclectic,organically integrate its advantages into itself,enrich its theoretical framework,and strengthen the construction of disciplines and departments to enhance its competitiveness.It is believed that Chinese medicine orthopedic chiropractic massage can have better development in the future and can make more contributions to the health of the world’s people.

A single micro-LED manipulation system based on micro-gripper

Micro-LEDs(μLEDs)have advantages in terms of brightness,power consumption,and response speed.In addition,they can also be used as micro-sensors implanted in the body via flexible electronic skin.One of the key techniques involved in the fabrication ofμLED-based devices is transfer printing.Although numerous methods have been proposed for transfer printing,improving the yield ofμLED arrays is still a formidable task.In this paper,we propose a novel method for improving the yield ofμLED arrays transferred by the stamping method,using an innovative design of piezoelectrically driven asymmetric micro-gripper.Traditional grippers are too large to manipulateμLEDs,and therefore two micro-sized cantilevers are added at the gripper tips.AμLED manipulation system is constructed based on the micro-gripper together with a three-dimensional positioning system.Experimental results using this system show that it can be used successfully to manipulateμLED arrays.

Pre‑hatch thermal manipulation of embryos and post‑hatch baicalein supplementation mitigated heat stress in broiler chickens

Background High environmental temperatures induce heat stress in broiler chickens,affecting their health and pro-duction performance.Several dietary,managerial,and genetics strategies have been tested with some success in mitigating heat stress(HS)in broilers.Developing novel HS mitigation strategies for sustaining broiler production is critically needed.This study investigated the effects of pre-hatch thermal manipulation(TM)and post-hatch baica-lein supplementation on growth performance and health parameters in heat-stressed broilers.Results Six hundred fertile Cobb 500 eggs were incubated for 21 d.After candling on embryonic day(ED)10,238 eggs were thermally manipulated at 38.5℃ with 55%relative humidity(RH)from ED 12 to 18,then transferred to the hatcher(ED 19 to 21,standard temperature)and 236 eggs were incubated at a controlled temperature(37.5℃)till hatch.After hatch,180-day-old chicks from both groups were raised in 36 pens(n=10 birds/pen,6 replicates per treatment).The treatments were:1)Control,2)TM,3)control heat stress(CHS),4)thermal manipulation heat stress(TMHS),5)control heat stress supplement(CHSS),and 6)thermal manipulation heat stress supplement(TMHSS).All birds were raised under the standard environment for 21 d,followed by chronic heat stress from d 22 to 35(32–33℃ for 8 h)in the CHS,TMHS,CHSS,and TMHSS groups.A thermoneutral(22–24℃)environment was maintained in the Control and TM groups.RH was constant(50%±5%)throughout the trial.All the data were analyzed using one-way ANOVA in R and GraphPad software at P<0.05 and are presented as mean±SEM.Heat stress significantly decreased(P<0.05)the final body weight and ADG in CHS and TMHS groups compared to the other groups.Embryonic TM significantly increased(P<0.05)the expression of heat shock protein-related genes(HSP70,HSP90,and HSPH1)and antioxidant-related genes(GPX1 and TXN).TMHS birds showed a significant increment(P<0.05)in total cecal volatile fatty acid(VFA)concentration compared to the CHS birds.The cecal microbial analysis showed significant enrichment(P<0.05)in alpha and beta diversity and Coprococcus in the TMHSS group.Conclusions Pre-hatch TM and post-hatch baicalein supplementation in heat-stressed birds mitigate the detrimental effects of heat stress on chickens’growth performance,upregulate favorable gene expression,increase VFA produc-tion,and promote gut health by increasing beneficial microbial communities.

Artificial intelligence awareness and perceptions among pediatric orthopedic surgeons:A cross-sectional observational study

BACKGROUND Artificial intelligence(AI)is a branch of computer science that allows machines to analyze large datasets,learn from patterns,and perform tasks that would otherwise require human intelligence and supervision.It is an emerging tool in pediatric orthopedic surgery,with various promising applications.An evaluation of the current awareness and perceptions among pediatric orthopedic surgeons is necessary to facilitate AI utilization and highlight possible areas of concern.AIM To assess the awareness and perceptions of AI among pediatric orthopedic surgeons.METHODS This cross-sectional observational study was conducted using a structured questionnaire designed using QuestionPro online survey software to collect quantitative and qualitative data.One hundred and twenty-eight pediatric orthopedic surgeons affiliated with two groups:Pediatric Orthopedic Chapter of Saudi Orthopedics Association and Middle East Pediatric Orthopedic Society in Gulf Cooperation Council Countries were surveyed.RESULTS The pediatric orthopedic surgeons surveyed had a low level of familiarity with AI,with more than 60%of respondents rating themselves as being slightly familiar or not at all familiar.The most positively rated aspect of AI applications for pediatric orthopedic surgery was their ability to save time and enhance productivity,with 61.97%agreeing or strongly agreeing,and only 4.23%disagreeing or strongly disagreeing.Our participants also placed a high priority on patient privacy and data security,with over 90%rating them as quite important or highly important.Additional bivariate analyses suggested that physicians with a higher awareness of AI also have a more positive perception.CONCLUSION Our study highlights a lack of familiarity among pediatric orthopedic surgeons towards AI,and suggests a need for enhanced education and regulatory frameworks to ensure the safe adoption of AI.

A 1-bit electronically reconfigurable beam steerable metasurface reflectarray with multiple polarization manipulations

A 1-bit electronically controlled metasurface reflectarray is presented to achieve beam steering with multiple polarization manipulations. A metsurface unit cell loaded by two PIN diodes is designed. By switching the two PIN diodes between ON and OFF states, the isotropic and anisotropic reflections can be flexibly achieved. For either the isotropic reflection or the anisotropic reflection, the two operation states achieve the reflection coefficients with approximately equal magnitude and 180°out of phase, thus giving rise to the isotropic/anisotropic 1-bit metasurface unit cells. With the 1-bit unit cells, a 12-by-12 metasurface reflectarray is optimally designed and fabricated. Under either y-or x-polarized incident wave illumination, the reflectarray can achieve the co-polarized and cross-polarized beam scanning, respectively, with the peak gains of 20.08 d Bi and 17.26 d Bi within the scan range of about ±50°. With the right-handed circular polarization(RHCP) excitation, the left-handed circular polarization(LHCP) radiation with the peak gain of 16.98 d Bic can be achieved within the scan range of ±50°. Good agreement between the experimental results and the simulation results are observed for 2D beam steering and polarization manipulation capabilities.

A Clinical Observation of Functional Abdominal Pain Syndrome in Patients Treated by Traditional Chinese Spinal Orthopedic Manipulation

Objective： To evaluate the clinical effect of traditional Chinese spinal orthopedic manipulation（TCSOM） in treating patients with functional abdominal pain syndrome（FAPS） in comparison with Pinaverium Bromide（Dicetel, PBD）, and to assess a possible cause for FAPS. Methods： Eighty patients with FAPS were randomly and equally assigned to the TCSOM group and PBD group according to the random number table. All patients in the TCSOM group were treated with a maximum of 5 times of spinal manipulations. Patients in the PBD group were instructed to take 50 mg 3 times a day, consistently for 2 weeks. The symptoms of pre-and post-treatment were assessed on a visual analog scale（VAS） pain score. A symptom improvement rating（SIR） was implemented to evaluate the effects of the treatments. Results： The symptoms of 27 cases of the TCSOM group were relieved soon after the first TCSOM treatment and 9 cases were significantly improved. The VAS pain scores in the TCSOM group were significantly lower than those in the PBD group after 2 weeks treatment. According to the SIR based on VAS, the TCSOM group included 30 cases with excellent results, 7 cases with good, and 3 cases with poor. Adverse events to the treatment were not reported. Based on VAS, the PBD group reported 8 cases with excellent results, 10 cases with good and 22 cases with poor. There was a significant difference between the two groups（P〈0.01）. Conclusions： The displacement of intervertebral discs and/or vertebra in the thoracic or lumbar region seems to be a contributing factor in the symptoms of FAPS. TCSOM is an effective treatment for FAPS.

The Manipulation of Power Discourse on Religious Translation Both in the West and in China

As a cross-lingual, cross-cultural, cross-time-and-space communication, religious translation has inevitably been stamped, from the very beginning, with the brand of ideology and has, more or less, been restrained by political factors there and then. The translated version, very often, cannot truly mirror the essence of the source text mainly because translation is manipulated by the power discourse in the target culture.

Manipulation for degenerative lumbar spondylolisthesis:A systematic review of randomized controlled trials

Objective: To assess the effectiveness and safety of manipulation intervention for degenerative lumbar spondylolisthesis(DLS).Methods: This is a systematic review and meta-analysis. A full-scale retrieval method was performed until February 1, 2021, including nine databases. The homogeneity of different studies was summarized using the Review Manager. The quality of studies was determined with the Cochrane risk-of-bias tool.The evidence quality was graded with the Grading of Recommendations, Assessment, Development, and Evaluations approach.Results: A total of 6 studies involving 524 participants were included. The review demonstrated that manipulation has statistically significant improvements for treating DLS according to Japanese Orthopedic Association scores(mean difference, 3.76;95% confidence interval, 2.63 to 4.90;P <.001) and visual analog scale scores(mean difference,-1.50;95% confidence interval,-1.66 to-1.33;P <.001)compared to the control group. One study reported that the difference in the Oswestry Disability Index between the traction group and the combination of manipulation and traction group was statistically significant(P <.05), while another reported that manipulation treatment can significantly improve the lumbar spine rotation angle on X-ray images compared with the baseline data(P <.05). Moreover, the manipulation group(experimental group) had fewer adverse events than the lumbar traction group(control group).Conclusion: Manipulation intervention is more effective and safer for DLS. Nevertheless, large-scale randomized controlled trials are required to confirm the current conclusions.
