PURPOSE:
Hand-sewn anastomosis as the gold standard of vascular anastomosis cannot fully meet the requirements of vascular anastomosis in speed and quality. Various vascular couplers have been developed to ameliorate this situation. Most of them are mainly used for venous anastomosis rather than arterial anastomosis. Although it is generally acknowledged that in almost all operations involving vascular reconstruction, it is the arteries that need to be anastomosed faster and more accurately and not the veins. A dedicated device is needed for creating arterial anastomosis in an easy, timesaving, less damaging but reliable procedure. Therefore, we plan to develop a novel arterial coupler device and test pre-clinical safety and effectiveness.
METHODS:
In this cohort study, the rationality of this novel arterial coupler was preliminarily tested by finite element analysis before it was manufactured. Several factors restrict the use of vascular couplers in arterial anastomosis, such as arterial eversion, fixation, etc. The manufactured arterial couplers underwent in vitro and in vivo experiments. In vitro, isolated arteries of beagles were anastomosed with the assistance of an arterial coupler, and the anastomosed arteries were evaluated through anti-traction tests. In animal experiments, the bilateral femoral arteries of 5 beagles served as a control group. After dissection, the femoral artery on one side was randomly selected to be anastomosed with a quick arterial coupler (QAC) (QAC group), and the femoral artery on the other side was anastomosed by the same person using an end-to-end suture technique with a 6-0 Prolene suture (suture group). The bilateral femoral arteries of 5 beagles were used for coupler-assisted anastomosis and hand-sewn anastomosis in vivo, respectively. Success rate, blood loss, anastomotic time, clamp time, total operation time, and patency rate were recorded. The patency of anastomosed arteries was assessed using vascular Doppler ultrasound, electromagnetic flowmeter, and pathological examination (6 weeks after surgery).
RESULTS:
As a novel arterial coupler, QAC was successfully designed and manufactured by using poly lactic-co-glycolic acid raw materials and 3-dimensions printing technology. Its rationality was preliminarily tested through finite element analysis and related mechanical analysis methods. The isolated arteries were successfully anastomosed with the assistance of QAC in vitro testing, which showed good anti-traction properties. In animal studies, QAC-assisted arterial anastomosis has superior profiles compared to hand-sewn anastomosis in anastomotic time (7.80 ± 1.41 vs. 16.38 ± 1.04 min), clamp time (8.80 ± 1.41 vs. 14.14 ± 1.57 min), and total operation time (46.64 ± 2.38 vs. 51.96 ± 3.65 min). The results of electromagnetic flowmeter, vascular Doppler ultrasound, and pathological examination showed that QAC-assisted anastomotic arteries were superior to hand-sewn arteries in terms of postoperative blood flow (16.86 ± 3.93 vs. 10.36 ± 0.92 mL/min) and vascular patency in 6 weeks after surgery.
CONCLUSION
QAC is a well-designed and easily maneuverable device specialized for end-to-end arterial anastomosis. Application of this device may decrease thermal ischemia time and improve the patency of anastomotic arteries, thus, improving outcomes.

The paper presents professor WU Han-qing's experience in treatment of lumbar disc herniation (LDH) with "sinew-bone three needling technique" of Chinese medicine. Based on the theory of meridian sinew, the points are located by "three-pass method" in terms of the distribution of meridian sinew and syndrome/pattern differentiation. The cord-like muscles and adhesion are relieved by relaxing technique to work directly on the affected sites and alleviate the local compression to the nerve root. The needle technique is operated flexibly according to the affected regions involved, due to which, the needling sensation is increased while the safety ensured. As a result, the meridian qi is enhanced, the mind and qi circulation is regulated; and the clinical effect is improved.

This paper summarizes the status of application and research of Fu's subcutaneous needling for peripheral facial paralysis, and the characteristics of different stages of peripheral facial paralysis treated with Fu's subcutaneous needling are analyzed from the aspects of intervention timing, protocol design, needle insertion point, sweeping and reperfusion activity, tube retaining time and acupuncture frequency. It is found that there are no norms and standards in sweeping and reperfusion, tube retention and acupuncture frequency in clinical application,and the exploration of staged treatment is insufficient in the research. In the future, it is necessary to form standardized operation to promote clinical promotion, and improve the research on treatment rules and mechanism according to the characteristics of disease stage.

The paper introduces professor GAO Shu-zhong's understanding on "seeking yin from yang needling method" and its clinical application on the basis of "qi street" and "four seas" theories. Through professor GAO's clinical practice for years, he integrates and extendes the theories of "seeking yin from yang", "qi street" and "four seas" in Huangdi Neijing (The Yellow Emperor's Inner Classic). In this specific acupuncture method, in reference with the theories of "qi street" and "four seas", acupuncture is exerted on yang part of body, e.g. the back and lumber region to treat the diseases of yin parts, e.g. the chest and abdomen, which is differentiated as yin-yang imbalance in pathogenesis. In order to fully explain the clinical curative effect of "seeking yin from yang needling method", the common diseases in clinic, e.g. the disorders of heart, spleen and stomach systems, as well as the gynecology are taken as examples in the paper.

OBJECTIVE:
To observe the effect of lateral needling at Lianquan (CV 23) for post-stroke dysphagia, and explore its mechanism.
METHODS:
A total of 64 patients with post-stroke dysphagia were randomly divided into an observation group and a control group, 32 cases in each group. Both groups were treated with conventional basic treatment. The observation group was treated with lateral needling at CV 23, without needle retaining, once a day. The control group was treated with swallowing rehabilitation training, once a day. Both groups were treated for 5 days a week, with 2 days interval, 1 week as one course and 4 courses were required. Before and after treatment, the Kubota water swallowing test grade and standardized swallowing assessment (SSA) score were compared in the two groups. Before and after treatment, the video fluoroscopic swallowing study (VFSS) was used to measure the hyoid bone movement displacement and pharyngeal delivery time in the observation group.
RESULTS:
Compared before treatment, the Kubota water swallowing test grade after treatment was improved in the two groups (P<0.05), and the observation group was superior to the control group (P<0.05); the SSA scores after treatment were decreased in the two groups (P<0.05), and the observation group was lower than the control group (P<0.05). Compared before treatment, the hyoid bone movement displacement was increased and pharyngeal delivery time was shortened after treatment in the observation group (P<0.05).
CONCLUSION
Lateral needling at CV 23 could improve dysphagia symptoms in patients with post-stroke dysphagia, its mechanism may be related to the increasing of hyoid bone movement displacement and shortening of pharyngeal delivery time.
