This article summarizes Professor Li Ziyong's clinical experience with the round-sharp needle.As one of the core needle types in the Huang Di Nei Jing(The Yellow Emperor's Inner Classic)nine-needle system,the round-sharp needle has long been marginalized in clinical practice due to historical discontinuities in its transmission and insufficient research on its morphological characteristics,resulting in its unique therapeutic value remaining largely unrecognized.Through nearly three decades of clinical practice,Professor Li innovatively proposed the acupuncture concept of"unblocking passages and guarding the pivotal mechanism",guided by the Yellow Emperor's Inner Classic principle that"ordinary practitioners focus on the joints,while superior practitioners focus on the pivotal mechanisms".Under this theoretical framework,he has extensively applied the round-sharp needle in clinical settings.With its unique design combining rounded and sharp features,the round-sharp needle demonstrates remarkable clinical efficacy by intervening at the fascial layer and releasing local fascial adhesions.It exhibits rapid onset and stable therapeutic outcomes.This article systematically reviews Professor Li's understanding of the round-sharp needle,its key operational techniques,and clinical case studies,aiming to establish a replicable paradigm for its modern application and promote the clinical translation of classical acupuncture theory.

Objective:To explore the effect of probiotics Lactiplantibacillus plantarum(LP) WCFS1 by gavage on acute necrotizing pancreatitis (ANP) and associated ileum injury in mice. Methods:Twenty-four healthy male mice were gavaged with broad-spectrum antibiotics for 3 weeks to establish microbiota-depleted mice, and then randomly divided into control group (CON), ANP model group (ANP), LP gavage group (LP) and LP gavage and ANP induced group (LP+ ANP) , with 6 mice in each group. Mice in LP and LP+ ANP group were treated by gavage of LP (1×10 9 CFU/ml, 0.2 ml/day per mouse) for 1 week, while CON and ANP were gavaged with sterile phosphate buffered saline for 1 week instead. The ANP model was induced by intraperitoneal injection with caerulein (100 μg/kg) for 10 times with 1-hour interval between two injections and the 10th injection with lipopolysaccharide(LPS) 5 mg/kg intraperitoneally, and the mice were sacrificed 2 h later. Levels of LP in stool and ileal mucosa were detected by real-time PCR; the pancreas and ileum were collected for pathological examination to observe the extent of tissue inflammation and to score the pathology. Serum amylase activities were determined by enzymatic kinetic chemistry; serum inflammators levels and intestinal permeability were detected by ELISA; levels of inflammators in pancreatic and ileal tissues were detected by real-time PCR; ileal tight-junction proteins (occludin, claudin-1 and ZO-1) were measured by immunofluorescence staining. Results:LP levels in the stool and ileal mucosa of mice were significantly increased after LP gavage, and the differences were statistically significant (913.30±39.12 vs 2.39±1.39, 23.11±0.50 vs 1.38±0.28, all P value <0.05). The pathological scores of pancreatic tissue of CON, LP, ANP and LP+ ANP group were (0.26±0.41), (0.17±0.26), (8.55±0.46) and (6.30±0.45); the serum amylase activities were (219.70±19.73), (217.60±11.30), (2896.24±98.32) and (1837.13±131.60)U/L, IL-1β were (0.87±0.28), (1.4±0.85), (67.41±6.45) and (36.33±5.65)pg/ml, IL-6 were (0.74±0.27), (0.16±0.16), (280586.12±39163.92) and (107912.75±31283.47)pg/ml, IL-10 were (35.52±5.27), (50.99±15.34), (2008.45±184.83) and (3070.35±403.71)pg/ml; the expression level of pancreatic IL-1β mRNA was 1.42±0.39, 0.95±25, 20.53±0.50 and 10.69±1.01, IL-6 mRNA was 1.31±0.44, 0.93±0.023, 21.97±1.71 and 11.54±1.75, IL-10 mRNA was 0.93±0.14, 0.75±0.15, 0.99±0.21 and 1.76±0.19; there was no significant difference between LP and CON group, and pancreatic pathological scores, serum amylase、IL-1β and IL-6 levels, and the expression level of pancreatic IL-1β and IL-6 mRNA were significantly decreased in LP+ ANP group compared with those in ANP group, while serum IL-10 levels and the expression level of pancreatic IL-10 mRNA were significantly increased compared with ANP group, and all the differences were statistically significant (all P values <0.05). The pathological scores of ileal tissue of CON, LP, ANP and LP+ ANP group were 0, 0, (3.17±0.41) and (1.67±0.52); the levels of serum DAO of CON, LP, ANP and LP+ ANP group were (0.03±0.03), (0.02±0.02), (0.50±0.05) and (0.49±0.06)ng/ml; LPS levels were (2.75±0.35), (3.74±0.28), (7.19±0.92) and (5.88±0.38)ng/ml; the expression level of ileal IL-1β mRNA was 1.21±0.20, 1.17±0.09, 1.81±0.25 and 1.63±0.21; IL-6 mRNA was 1.01±0.29, 2.83±0.42, 54.45±8.50 and 16.87±4.42; IL-10 mRNA was 1.12±0.41, 6.09±2.51, 11.65±1.47 and 29.86±2.93. There was no significant difference between LP and CON group, except that the ileal IL-10 mRNA expression was significantly higher than that of CON group. Ileal pathological scores, serum LPS levels and the expression level of ileal IL-6 mRNA were significantly lower in LP+ ANP group than those in ANP group, while the expression level of ileal IL-10 mRNA was significantly higher than that of ANP group; the expression of ileal tight junction proteins (ocludin, claudin-1, ZO-1) was significantly higher than those in ANP group, and all the differences were statistically significant (all P values <0.05). Conclusions:LP WCFS1 gavage could ameliorate the injury of pancreatic and ileal barrier in caerulein-induced ANP mice.

Moyamoya disease(MMD)is a bilateral stenosis occlusional disease that selectively affects the superior segment of clinoid of the internal carotid artery with secondary abnormal vascular network formation at the base of the skull.Intracranial and extracranial vascular reconstruction is the main treatment of moyamoya disease.However,moyamoya disease revasectomy still faces many challenges,with high requirements of surgical techniques and high risk of complications.In this paper,the perioperative management of cerebrovascular reconstruction in moyamoya disease was discussed in terms of surgical indications,surgical timing,patient management,surgical methods of cerebrovascular reconstruction and postoperative complications,so as to provide reference for improving the prognosis of patients.

OBJECTIVED: To explore the prevalence and risk factors of type 2 diabetes mellitus (T2DM) and impaired glucose regulation (IGR) in Zhangzi Island of Dalian, additionally to provide a better understanding of further intervention. METHODS: A cross-sectional study was performed in 907 residents aged over 18 years from Zhangzi Island of Dalian. The questionnaire, physical measurement, food intake frequency and previously dietary investigation were used in the analysis. Simultaneously, a series of biochemistrical and immune index was measured, including blood uric acid, blood sugar, total cholesterol, triacylglycerol, as well as serum insulin.RESULTS: The recovery rate of questionnaire was 95.9%, which demonstrated that the prevalence rates of T2DM and IGR in Zhangzi Island were 11.36% and 37.38%, there was no significant differences between males and females (P > 0.05). Only 29.13% of the people with T2DM were aware of the condition. The prevalence of DM and IGR were increased significantly with age (P < 0.01). The results of the logistic regression showed that age, education, alcohol drinking and hypercholesteremia were the risk factors of IGR. In addition, age, education, hypercholesteremia, hypertriglyceridemia, body mass index and hypertension were the important risk factors for the development of DM. CONCLUSION: The prevalence rates of T2DM and IGR in Zhangzi Island of Dalian are high with a low awareness. Health promotion on lifestyle changes may help to increase the public awareness and reduce the prevalence.
