How to Insert Acupuncture Needles into the Subacromial Space through LI15

LI15 is an important acupuncture point to treat shoulder pain. There are 4 needling methods for LI15 in the textbook; 1 method requires the insertion of the needle horizontally between the acromion and the great tuberosity of the humerus with the arm lowered for supraspinatus tendonitis. This method is also applicable for all conditions of rotator cuff disease, but it has not previously been described in detail. Providing X-ray scans and describing needle direction and depth of insertion will provide evidence for needling with the arm down as an effective stimulation of the subacromial space. Firstly, for this technique, with the arm raised, a concave point is located between the front edge of the acromion and the humerus, and the lower upper arm. Secondly, the acupuncture needle is inserted slightly posteriorly towards the supraspinous fossa, in the direction of the supraspinatus tendon and to a depth of 30-40 mm.

Effect of acupuncture anesthesia based on nanomaterial sensor on cognitive function after one-lung ventilation thoracotomy

In this work, a new type of nanomaterial sensing acupuncture needle was developed to improve patient comfort and treatment effectiveness. Based on the convenient electrochemical casting process, multilayer nano-tapered holes were constructed on the needle surface to form a porous nano-sensing acupuncture needle (PNAN), which further increases the interface area of the acupuncture needle. To evaluate the effect of PNAN-induced anesthesia on cognitive function after one-lung ventilation and thoracotomy, 60 patients with esophageal cancer undergoing thoracotomy were randomly divided into an acupuncture-induced anesthesia (AIA) group and a conventional anesthesia (CA) group. The recovery time for cognitive function and the incidence of cognitive impairment in the PNAN-induced anesthesia group after one-lung ventilation and thoracotomy were significantly lower than those of the CA group (P < 0.05). The scores from the Mini Mental State Examination Scale (MMSE) and Self-Rating Anxiety Scale (SAS) for the AIA group were lower than the preoperative scores and were better than those for the CA group (P < 0.05). In addition, after one-lung ventilation and thoracotomy, the concentrations of cytokines and catecholamines (CAs) in both groups were lower than the preoperative values, and the levels of cytokines and CAs in the AIA group were significantly lower than those of the CA group. Therefore, acupuncture anesthesia based on a nanomaterial sensor can significantly improve the cognitive function of patients after one-lung ventilation and thoracotomy, inhibit inflammatory factors, and provide an optimal curative effect.

Laparoscopic removal of an aberrant acupuncture needle in the gluteus that reached the pelvic cavity: a case report

Background Intrapelvic aberrant needles are rare in clinical practice. Long-term foreign bodies in the abdominal cavity may form granulation tissue or an abscess, and may cause organ injury. Therefore, such foreign bodies need prompt removal. Case presentation A 26-year-old male athlete was referred to our hospital for investigation of an aberrant acupuncture needle in the gluteus. The needle was unable to be removed during acupuncture treatment, and the end broke off and remained in the gluteus. Abdominal X-ray examination showed a thin, 40-mm-long, metallic foreign body resembling an acupuncture needle. Abdominal computed tomography showed an abnormal shadow in the gluteus. However, it was unclear whether the tip of the needle reached the pelvic cavity. Thus, it was decided to surgically extract the needle via laparoscopic surgery under X-ray guidance as a safe and minimally invasive method. Although X-ray fluoroscopy confirmed that the aberrant needle was located in the gluteus, the needle could not be felt with the forceps, as the peritoneum surrounding the needle had granulomatous changes due to inflammation. Therefore, the retroperitoneum was further dissected to search for the needle. Once the needle was identified, its flexibility enabled it to be easily removed by grasping it directly with a needle holder. The length of the aberrant needle was 40 mm. The postoperative course was uneventful, and the patient was discharged from hospital on postoperative day 2. Conclusions When a foreign body remains in the gluteus and its tip touches intrapelvic organs, such as the rectum, it is critical to determine the best approach for its safe removal. Given the anatomical location of the foreign body and the patient background, laparoscopic removal was considered the best approach in the present case.

MÉTODOS DE INJEÇÃO DA AMOSTRA EM MICROSSISTEMAS ELETROFORÉTICOS

SAMPLE INJECTION METHODS IN ELECTROPHORETIC MICROSYSTEMS. Electrophoresis is by far the most popular separation method implemented in microscale, most probably due to its instrumental simplicity, low cost and portability. Due to the increasing use of miniaturized electrophoretic systems, the study of fundamental aspects can improve the development of methodologies for several applications. One of the major challenges related to electrophoresis chips refers to the sample injection mode, in this way, this study presents a review on sample injection methods for microchip electrophoresis covering electrokinetic and hydrodynamic approaches, describing theoretic and instrumental aspects. Since the sample volume affects the analytical performance, the precise and reproducible control of the sample amount to be introduced into the separation channel is highly desirable to ensure reliable chemical analysis. Electrokinetic modes based on floating, pinched and gated protocols are presented and discussed providing an overview about the electrokinetic control of the sample through three methodologies. In the same way, hydrodynamic techniques including the use of microfabricated valves and pumps, syringe pumps, electronic micropipettes, rubber suction bulb and acupuncture needle are approached, thus expanding the view of hydrodynamic injectors based on classical and alternative methods.

Historical Facts of Acupuncture and Traditional Chinese Veterinary Medicine—A Letter to the Editor Re: Magalhães-Sant’Ana, M. Animals 2019, 9, 168

A recent viewpoint paper by Manuel Magalhães-Sant’Ana (2019) discussed the evidence regarding history, conceptions and modern research related to Traditional Chinese Veterinary Acupuncture (TCVA). Based on the observation of an illustration of nine needles, the author suggested that the needles used in acupuncture are more like lancets than needles in ancient times; to support the view that acupuncture is analogous to bloodletting. In addition; the author does not believe that TCVA has not been practiced for thousands of years. This letter documents that the prototype of the modern filiform acupuncture needle has appeared as early as the Han Dynasty and that modern needles did not evolve from lancets. In addition, there is proof based on existing ancient books that TCVA has a history of thousands of years.
