Objective: To observe the clinical efficacy of pushing Qiaogong point with varying intensities for treating stage Ⅰ essential hypertension. Methods: A total of 72 patients diagnosed with stageⅠ essential hypertension were enrolled in this study. They were divided into three groups using the random number table method, including a control group, a gentle pushing group, and a heavy pushing group, with 24 patients in each group. All three groups received the same therapeutic lifestyle interventions. The control group received no additional interventions, the gentle pushing group received additional pushing Qiaogong point with gentle strength, and the heavy pushing group received additional pushing Qiaogong point with heavy strength. The treatment duration was 4 weeks, followed by a 4-week follow-up period, during which blood pressure changes were observed and analyzed in all three groups. Results: After treatment, the blood pressure levels in all three groups showed a significant decrease (P<0.05). The effective rate in the control group was 43.5％, in the gentle pushing group was 78.3％, and in the heavy pushing group was 33.3％. The reduction in blood pressure levels in the gentle pushing group was significantly superior to that in both the control group and the heavy pushing group, indicating inter-group statistical significance (P<0.01). The efficacy of the heavy pushing group was comparable to that of the control group, indicating no statistical significance (P>0.05). During the follow-up period, compared with the end of the treatment within the same group, the blood pressure levels remained stable in both the control group and the gentle pushing group, indicating no intra-group statistical significance (P>0.05). The heavy pushing group showed a significant decrease in diastolic blood pressure (DBP) and mean blood pressure (MBP) compared with the end of the treatment, indicating intra-group statistical significance (P<0.05). During the follow-up, the gentle pushing group had lower systolic blood pressure (SBP) and MBP compared with both the heavy pushing group and the control group, indicating inter-group statistical significance (P<0.01), while there was no inter-group statistical significance in comparing the DBP (P>0.05). There was no statistical significance in comparing the SBP, DBP, and MBP between the heavy pushing group and the control group (P>0.05). Conclusion: Pushing Qiaogong point with gentle strength combined with lifestyle interventions showed a higher effective rate and long-term blood pressure stability in the treatment of stage Ⅰ essential hypertension. Pushing Qiaogong point with varying intensities showed varying effects on patients with stage Ⅰ essential hypertension.

Study on the antipyretic mechanism of large pushing Tianheshui for young rabbits with endotoxin-induced fever / 针灸推拿医学（英文版）

Objective:To observe the effect of large pushing Tianheshui manipulation intervention on the body temperature of young rabbits with endotoxin-induced fever and discuss its antipyretic mechanism.Methods:Thirty-two young rabbits meeting the standards were selected from 40 ordinary young male New Zealand rabbits after being adapted for 7 d,and randomly divided into a normal group,a model group,a large pushing Tianheshui group,and an ibuprofen group according to the random number table method,with 8 rabbits in each group.Rabbits in the model group,the large pushing Tianheshui group,and the ibuprofen group were subjected to preparing the endotoxin-induced fever model by intravenous lipopolysaccharide from the marginal ear vein.Rabbits in the large pushing Tianheshui group received Tuina(Chinese therapeutic massage)manipulation intervention 1.5 h and 2.5 h after modeling,respectively.Rabbits in the ibuprofen group were intragastrically given ibuprofen suspension 1.5 h after modeling.The dynamic changes in body temperature were observed for the young rabbits after fever modeling.Enzyme-linked immunosorbent assay was used to determine the content changes in positive mediators of hypothalamic body temperature,including prostaglandin(PG)E2 and cyclic adenosine monophosphate(cAMP),as well as negative mediators of hypothalamic body temperature,including arginine vasopressin(AVP)and α-melanocyte stimulating hormone(α-MSH).Results:The body temperature of the young rabbits in the model group was significantly higher than that in the normal group at 0.5-4.0 h,5.0 h,and 5.5 h after modeling(P＜0.01),showing two obvious fever peaks in the model group at 1.5 h and 3.0 h after modeling,respectively,with the highest peak at 1.5 h.Compared with the model group,body temperatures of the large pushing Tianheshui group and the ibuprofen group decreased significantly after 0.5 h of intervention(P＜0.05).Compared with the normal group,the contents of PGE2 and cAMP were significantly increased(P＜0.05),and the contents of AVP and α-MSH were significantly decreased(P＜0.01)in the hypothalamus of the model group.Compared with the model group,the contents of PGE2 and cAMP were significantly decreased(P＜0.01),and the levels of AVP and α-MSH were significantly increased(P＜0.01)in the hypothalamus in the large pushing Tianheshui group and the ibuprofen group.There were no significant differences in the PGE2,cAMP,AVP,and α-MSH contents in the hypothalamus between the ibuprofen group and the large pushing Tianheshui group(P＞0.05).Conclusion:Large pushing Tianheshui manipulation has a significant antipyretic effect on endotoxin-induced fever in young rabbits.The mechanism may be related to inhibiting the positive regulators(PGE2 and cAMP)and promoting the negative regulators(AVP and α-MSH)of hypothalamic control of body temperature.

Body Packer y Body Stuffer: Serie de Casos. Revisión / Body Packer y Body Stuffer: serie de casos. Revision

"Body packing", "Body pushing" y "Body stuffing" son distintas formas de transportar sustancias ilegales dentro del cuerpo humano. Frente al ingreso en la unidad de emergencias de un "Body Packer", conocido como "tragador de paquetes" con fines de contrabando o un "Body Stuffer" llamados "tragadores rápidos", quienes ingieren en forma compulsiva paquetes manufacturados para la venta de sustancias ante la posibilidad de ser sorprendidos por agentes de la ley; se plantean una serie de desafíos en cuanto al tratamiento que al día de hoy permanecen en debate. Generalmente se prefiere mantener una conducta conservadora facilitando la expulsión de los paquetes. En aquellos casos en los que los pacientes presenten paquetes atascados o rotos o no mejoren con el tratamiento conservador, se recomienda el tratamiento quirúrgico.El presente trabajo tiene por objetivo reportar una serie de casos internados por ingesta de paquetes potencialmente peligrosos que se sometieron a una evacuación farmacológica y/o quirúrgica en 8 pacientes y una revisión bibliográfica sobre el tema.

"Body packing", "Body pushing", and "Body stuffing" are different ways to use the interior of the human body to transport illegal substances. In the face of a "Body Packer" or a "Body Stuffer" known as "fast swallowers", which are those cases in which they compulsively swallow manufactured packages for the sale of substances before the possibility of being surprised by law enforcement officers, a series of challenges present themselves regarding the treatment, which is currently up for debate. Generally, a conservative conduct is preferred, facilitating the expulsion of the packages. In those cases, in which patients have stuck or broken packages or do not improve with conservative treatment, surgical treatment is recommended.The present paper aims to report a series of cases in which the patients were admitted due to an intake of potentially dangerous packages and put through a pharmacological evacuation and/or surgical evacuation of 8 patients, and a bibliographical revision on the subject.

Elbow-Height Handle and Staggered Stance Exhibited Greatest Force in Pushing and Pulling: A Study among Malaysian Adults

@#Introduction: Pushing and pulling activities are common in daily life and industrial workplaces. These activities are potentially contributing to muscle fatigue in the back and shoulder if not managed ergonomically. Therefore, this study aimed to quantify the maximum strength of Malaysian adults in horizontal symmetrical two-handed pushing and pulling with different handle heights and stances. Methods: Forty-seven participants of 24 males and 23 females were recruited in pushing and pulling experiments. The participants were assistant engineers and postgraduate students of a technical university. The dependent variable was the magnitude of push/ pull force. The independent variables consisted of action, handle height and stances. The experimental design was set for 2 actions, 3 handle heights and 2 stances, yielding 12 variables combinations. Results: Key findings of this study revealed that combination of pull action, handle height at elbow level and staggered stance exhibited greatest force. On the contrary, combination of push action, handle height at knuckle level and parallel stance resulted in lowest force. In pushing test, both male and female participants obtained greatest force of 233.3 N and 121.7 N, respectively, when the handle height was at elbow level and staggered stance. Similarly, in pulling test, males and females obtained highest force of 242.9 N and 152.4 N, respectively. Conclusion: This study concluded that handle height at elbow level and staggered stance exhibited greatest force in pushing and pulling activities. This study provides information to individuals who involved in pushing and pulling tasks with least force exertion to minimize muscle fatigue in the back and shoulder. Future studies should consider the following recommendations: 1) Participants of study should involve manufacturing industry workers. 2) To study the effect of pushing and pulling tasks on muscle activity.

Evaluation of Interhandle Distance During Pushing and Pulling of a Four-Caster Cart for Upper Limb Exertion

BACKGROUND: This study examined the relationship between interhandle distances and upper limb exertion during simply pushing and pulling of a cart with four swivel wheels, defined by a roll box pallet (RBP) in a Japanese industrial standard. METHODS: Six healthy young male participants were asked to push and pull an RBP at a distance of 5.2 m under six conditions corresponding to different interhandle distances (40 cm, 60 cm, and 80 cm) and weights (130 kg and 250 kg). The upper limb exertion was studied by shoulder abduction and flexion, and elbow flexion, as well as surface electromyogram (EMG) in shoulder extensor, and elbow flexor and extensor. Participants were required to provide subjective evaluations on operability after each trial. RESULTS: Subjective operability indicated that a narrower interhandle distance had a better operability for pushing. Interhandle distance was also related to upper limb exertion especially for pushing. A narrow interhandle distance caused smaller shoulder adduction but larger elbow flexion. The normalized EMG data revealed that muscular activity became smaller with a narrow interhandle distance in shoulder extensor. During the pulling task, elbow flexion was smaller at a narrow interhandle distance, although subjective operability and normalized EMG were not significantly varied. CONCLUSION: A wider interhandle distance, such as 80 cm, was not suitable in the forwardbackward movement of the RBP. Therefore, this study concluded that an interhandle distance of 40 cm would be suitable for pushing and pulling an RBP to protect the workers' hands against the risk of injury by installing inner handles.

Objective To study the frequency and effective work/time ratio of pushing manipulation with one finger (PMOF). Methods One skilled expert and nine beginners of PMOF were chosen. The frequency, effective work time/ratio during different work periods were recorded and compared after the technique information of each subject operating PMOF was collected by Novel Pliance Mobile System software. Results The operation frequency of each subject was all below 110/min, while the frequency of skilled expert was about 78/min. The time ratio between secondary work period and primary work period for the skilled expert was smaller than that of beginners. Conclusions The operation frequency of PMOF is preferably at 78/min, and the preferred time ratio between secondary work period and primary work period should be slightly larger than 0.28.

Movement pattern and sEMG characteristics of upper limb muscles during one-finger pushing manipulation operation with different forces / 医用生物力学

Objective To observe the surface electromyography (sEMG) characteristics of upper limbs during one-finger pushing manipulation under different operating forces, so as to find out the muscle coordination movement pattern for key operating technology. Methods sEMG data of performing one-finger pushing manipulation by the expert, skilled and novice groups were collected. The manipulation force was divided into three different types, namely mild, moderate and severe. The continuous, stable data were adopted for analysis on Myo-Research software. Results Significant differences were found in the upper limb muscle integrated electromyography (iEMG) values (P0.05), with the flexor carpi ulnaris, deltoid, wrist flexors and extensors ranking the top three of iEMG ratio. The expert and skilled groups had the same core muscles in the same movement pattern during their manipulation operation, while the novice group had different core muscles under different forces. There were significant differences in co-contraction ratio among the expert, skilled and novice groups (P<0.01). The novice and expert groups had the highest and lowest co-contraction ratio, respectively, and the co-contraction ratio was gradually decreased with force increasing. During 6-minute manipulation operation, deltoid median frequency(MF) slope of the expert group was declined more slowly than that in the other two groups (P<0.05), which indicated that the expert group were better at resisting to fatigue. Conclusions The expert and skilled groups have the same sEMG characteristics during one-finger pushing manipulation operation with the same core muscles. The movement pattern of upper limb muscles is of regularity. The iEMG ratio, MF slope and co-contraction ratio can be used as reference standard for evaluating the durability, and homogeneity of the manipulation operation and normalization of force application.
