Through analyzing the every textual research literature on the origin of the location method of ashi points, it is pointed out that the location method of ashi points has been generalized. It is known through systematic research and theoretical identification that this method refers to the simple way to locate the points, originated from the folk, and it is widely used to find the sites for pain relief when compared to the official education of meridians and acupoints, as well as treatment. At the time with the shortage of medical services and supplies, the poor people had no alternative, which results in a certain limitation. Modern acupuncture practitioners must associate ashi points with the acupoints of fourteen meridians and the extraordinary points in clinical practice, and deepen the exploration with modern medical knowledge and technology adopted.

Objective:To investigate the application of different imaging methods of 99Tc m-pyrophosphate (PYP) in the diagnosis and pathological classification of cardiac amyloidosis (CA). Methods:A total of 31 patients (22 males, 9 females, age 21-81(57.2±13.4) years) with suspected CA who underwent 99Tc m-PYP dual-phase scintigraphy (early-phase: 1 h, delay-phase: 2-3 h) and SPECT/CT (1 h) between December 2018 and December 2019 in Peking Union Medical College Hospital were retrospectively included. Taking clinical diagnosis as the standard, the results of visual score (≥2, positive) and semi-quantitative values (heart to contralateral lung (H/CL)≥1.5, positive) of 99Tc m-PYP uptake in dual-phase scintigraphy and SPECT/CT imaging were analyzed. One-way analysis of variance and Bonferroni test were used to analyze the data. Results:Among 31 patients with suspected CA, 15 were clinically diagnosed as CA (5 patients with transthyretin-related CA (ATTR-CA) and 10 patients with light chain CA (AL-CA)) and 16 were diagnosed as non-CA. All 5 patients with ATTR-CA had positive dual-phase scintigraphy and SPECT/CT imaging results. Three out of 10 patients with AL-CA had positive early-phase scintigraphy whereas negative delay-phase scintigraphy and SPECT/CT imaging results. Sixteen patients who were clinically diagnosed as non-CA had negative dual-phase scintigraphy and SPECT/CT imaging results. The sensitivity (5/5), specificity (10/10), positive predictive value (5/5), negative predictive value (10/10) and accuracy (15/15) of delay-phase scintigraphy and SPECT/CT imaging were the same. Among 31 patients, 16 patients carried transthyretin-related (TTR) gene mutation, and 4 of them who clinically diagnosed as variant ATTR (ATTRv) had positive image findings while 12 of them who not clinically diagnosed as CA had negative image findings. There were significant differences in H/CL between ATTR-CA group and AL-CA group in early-phase (2.11±0.24 vs 1.31±0.07) and delay-phase (2.02±0.19 vs 1.30±0.05; F values: 75.41 and 87.15, Bonferroni test, both P<0.01). Conclusions:99Tc m-PYP delay-phase scintigraphy and SPECT/CT have high diagnostic efficiencies in ATTR-CA, helping to determine the pathological classification of CA; while early-phase scintigraphy has false positive results. Moreover, 99Tc m-PYP imaging is helpful to detect CA in patients with TTR gene mutation.

Objective:To investigate the feasibility and clinical efficacy of laparoscopic radical cholecystectomy(LRC) for gallbladder cancer.Methods:The clinical data of 247 patients with gallbladder cancer who underwent radical resection from Jan 2013 to Dec 2019 at Department of General Surgery, Sir Run Run Shaw Hospital affiliated to Zhejiang University School of Medicine was analyzed retrospectively. After propensity score matching, 54 patients were included in laparoscopic group and 103 in laparotomy group. The clinicopathological characteristics and the short- and long-term outcomes were compared.Results:Compared to the laparotomy group, patients in the laparoscopic group had less intraoperative blood loss [100(50,200)ml vs. 200(100,300) ml, Z=4.105, P<0.001], earlier postoperative oral diet[1.0(1.0,2.0) d vs. 2.0(1.0,4.0) d, Z=4.157, P<0.001]and drainage removal[6.5(4.0,12.5) d vs. 9.0(6.0,16.0) d, Z=2.769, P=0.006], shorter hospital stay[7.0(5.0,9.3) d vs. 9.0(8.0,14.0) d, Z=3.923, P<0.001]. The number of lymph node dissection in laparoscopic group was significantly lesser than that in open group [6(4,9) vs. 8(5,12), Z=2.639, P=0.008]. There were no significant differences between the two groups in postoperative complications, short-term and long-term survival outcomes. Conclusions:Laparoscopic radical surgery for gallbladder cancer is as safe and feasible, and identical survival prognosis as open surgery, and moreover a less traumatic procedure.

Objective:To understand the psychological status and nursing needs of maintenance hemodialysis (MHD) patients and provide reference for clinical targeted nursing.Methods:Using the phenomenological research method, a total of 15 patients with MHD in the First Affiliated Hospital of Zhengzhou University were selected as the research objects by the purposive sampling method, and they were given semi-structured individualized interviews. The Colaizzi 7-step analysis method was used to organize the data, extract the inductive themes and analyze the results.Results:The psychological status of MHD patients was repressed fear, despair and helplessness and acceptance. The nursing needs of MHD patients included disease-related knowledge needs, social support needs and health guidance needs.Conclusions:MHD patients have negative psychology. Medical staff need to understand the psychological status and nursing needs of patients and formulate targeted nursing interventions to meet the actual needs of patients and improve the quality of life of them.

Objective:To investigate the prevention effect of nurse-led peer support system on the postpartum posttraumatic stress disorder of primipara.Methods:A total of 74 cases of primipara were randomly divided into experimental group ( n=37) and control group ( n=37). The control group received routine nursing. The experimental group received nurse-led peer support intervention. The postpartum depression and postpartum posttraumatic stress disorder was assessed by using Edinburgh postnatal depression scale (EPDS) and impact of event scale-revised (IES-R) before and after intervention. Results:Before intervention, the socre of EPDS and IES-R was no statistical difference between experimental group and control group ( P>0.05). After intervention, the scores of EPDS and IES-R were significantly decreased in the experiment group [(5.41 ± 0.49) pionts, (16.56 ± 1.36) pionts] compared to the control group [(16.56 ± 1.36) pionts, (19.01 ± 1.98) pionts], the difference was statistically significant ( P<0.05). Conclusion:Nurse-led peer support system can alliviate postpartum depression and posttraumatic stress disorder status and promote the psychological health of primipara.

BACKGROUNDTo explore the possibility of the staging of pulmonary angiography with multi slice spiral CT (MSCT) and to evaluate its value in making surgical plan for patients with lung cancer.

METHODSMSCT with two-segment injection and three-protocol scan was performed in 73 patients with central type lung cancer. According to the site and degree, the involvement of pulmonary artery was divided into three grades and blindly compared with the surgery and pathology.

RESULTSMSCT in 68 cases (93.15%, 68/73) was successfully performed. The involvement of central pulmonary artery was grade I in 4 cases (5.88%, 4/68), grade II in 9 (13.23%, 9/68), and grade III in 55 (80.88%, 55/68). All patients with grade I underwent lobectomy. There was remarkable difference of lobectomy ratio between grade II and III (Chi-square=64.03, P < 0.005) and also between IIIa and IIIb (Chi-square=68.69, P < 0.005). All patients with grade IIIc were ruled out from surgery.

CONCLUSIONSThe staging of pulmonary angiography by MSCT is useful to demonstrate the site and degree of involvement of central pulmonary artery and provides more precise evidence of images for making surgical plan.
