The contents of Zhang Zhongjing's works Treatise on Exogenous Febrile Disease,the Jade Case Classic of the Golden Cabinet,and Essentials from the Golden Cabinet(collectively known as the three classical medical books of Zhang Zhongjing),as well as Important Formulas Worth A Thousand Gold Pieces and Supplement to"Important Formulas Worth a Thousand Gold Pieces",which were cited in the Arcane Essentials from the Imperial Library(Wai Tai Mi Yao Fang)during comparative proofreading were analyzed.Wai Tai Mi Yao Fang is a book edited and public by the Bureau of Revising Medical Books in Northern Song Dynasty.The contents in the collation records for Wai Tai Mi Yao Fang were compared to the original text of the above five classical medical books proofread in Song Dynasty.The results showed that:(1)the ministers of Song Dynasty which were in charge of the proofreading mainly took the previously-proofread books as references,and widely referenced to the other editions of Wai Tai Mi Yao Fang,which reflected the proofreading principles of the Bureau of Revising Medical Books in Northern Song Dynasty,i.e.,collecting various editions widely and then identifying similarities and differences;(2)the analysis of the collation record in Zhongjing's Treatise on Exogenous Febrile Disease by using comparative proofreading method plus reasoning proofreading method showed that,the medical knowledge of the ministers of Song Dynasty had some limitations;(3)some of the medical terminology used by the ministers of Song Dynasty in their collation record influenced the naming convention of later generations of medical science,for example,making the Piyue Pills be the synonym of the Maziren Wan(Maren Wan).The results indicated that the complexity and uncertainty of the textual content of the popular edition of Wai Tai Mi Yao Fang should deserve the attention,and their influences on the development of later generations'scholarship need further in-depth study.

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 investigate the clinical application of perioperative human serum albumin(HSA)in cardiac surgery in multiple regions in China,and to evaluate the rationality of its clinical application in conjunction with the clinical guidelines,in order to provide a reference for promoting the rational application of HSA.Methods The medical records of patients who underwent cardiac surgery from April to June 2019 in eight hospitals across the country were retrospectively collected.The statistical information on patients'general information,the dosage,course of treatment,and cost of HSA,and the serum albumin level before and after medication was analyzed to evaluate the use of HSA.Relevant evaluation criteria were established,and the rationality of its medication was evaluated.Results Data from a total of 449 patients were included for analysis,the appropriate rate of medication was 81.1％.The course of medication was mostly＞2-5 days and the total amount of HSA was mostly 50-99 g.The main purpose of medicaiton were improving colloid osmotic pressure,reducing exudation to improve interstitial edema,postoperative volume expansion.Conclusion Clinical attention should be paid to ensure the rational application of HSA in cardiac surgery during the perioperative period and prevent the abuse of blood products.

Objective:To investigate the role of survivin in the regulation of leptin expression and its sensitivity.Methods:Survivin was overexpressed in adipocytes via lentivirus, and the RNA-sequencing(RNA-seq) was used to explore the effect of survivin on the regulation of adipocyte secretory proteins. Survivin was overexpressed in the inguinal adipose tissue(iWAT) of mice by targeted injection of adeno-associated virus(AAV). The transcription levels of leptin and adiponectin were detected by realtime quantitative PCR(RT-qPCR), and the secretion levels of leptin and adiponectin in cellular supernatants and mice serum were detected by enzyme-linked immunosorbent assay(ELISA). The protein level of phosphorylated signal transducer and activator of transcription 3(STAT3) in hypothalamus was detected by Western blotting to investigate the effect of survivin on central leptin sensitivity.Results:Survivin overexpression in both 3T3-L1 and primary white adipocyte significantly down-regulated the leptin transcriptional expression without affecting the adipocyte differentiation( P<0.01). Overexpression of survivin significantly decreased leptin level without affecting the adiponectin levels in the cellular supernatant( P<0.001). Overexpression of survivin in iWAT via AAV injection, not only specifically down-regulated leptin transcriptional level in a dose dependent manner in local adipose tissue, but also led to a decrease in serum leptin level( P<0.05). In mice fed short-term high-fat diet, STAT3 phosphorylation level in hypothalamus significantly increased, suggesting improved central leptin sensitivity. Conclusion:Survivin could downregulate leptin expression and improve leptin sensitivity in high-fat diet induced obese mice.

Abstract: Objective To construct a shuttle vector pHT315-AaCPR100A with two spore-producing-dependent promoters and the target gene AaCPR100A in Escherichia coli-Bacillus thuringiensis. Methods The forward promoter of Cry3A, named Pro-1 (+), was amplified by PCR using pSVP27A plasmid as the template, and the target gene AaCPR100A was amplified using Aedes aegypti RNA reverse conversion cDNA as the template. The plasmid pHT315 was linearized by digestion with Hind Ⅲ and Sal Ⅰ. The forward promoter and the target gene were inserted into the linearized vector pHT315 successively by in-fusion cloning according to the transcription direction. The synthesized plasmid containing the Cry3A reverse promoter sequence was used as the template, and the Pro-1 (-) reverse promoter was amplified by PCR. The intermediate vector containing the forward promoter and the target gene was linearized by EcoR I restriction enzyme, and the reverse promoter was inserted downstream of the target gene by in-fusion cloning in the direction of transcription. Results By agarose gel electrophoresis, the forward promoter, target gene AaCPR100A and reverse promoter bands were clear and of good quality, which could be used for in-fusion cloning experiments. The two spore-producing-dependent promoters and target gene fragments were connected by In-fusion cloning. The recombinant vector pHT315-AaCPR100A was verified by PCR. The forward promoter, target gene fragment and reverse promoter were successfully amplified in the recombinant vector. Nucleotide sequencing verified that the sequencing results of the bidirectional promoter sequence and the target gene sequence were basically consistent with the sequence alignment results, which met the requirements of the construction of vector elements and proved that the recombinant vector was successfully constructed. Conclusions Based on the above results, this study proves that the recombinant shuttle vector with two spore-producing-dependent promoters can be successfully constructed by in-fusion cloning technology, laying the foundation for the construction of engineered Bacillus thuringiensis expressing dsRNA of AaCPR100A.

Objective:To investigate the application value of mixed reality technology in surgical conversation of laparoscopy radical resection of gastric cancer.Methods:The prospective randomized controlled study was conducted. There were 80 family members of patients with gastric cancer who were admitted to Nanfang Hospital of Southern Medical University from June 2021 to December 2022 being selected as subjects. All patients underwent laparoscopic radical resection of gastric cancer. Based on random number table, all subjects were allocated into the control group and the experiment group. Subjects in the control group performed routine surgical conversation and subjects in the experiment group performed surgical conversation based on mixed reality technology. Observation indicators: (1) baseline data of the subjects; (2) anxiety assessment of the subjects. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for inter-group comparison. Repeated measurement data were analyzed using the repeated ANOVA. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Wilcoxon rank sum test. Results:(1) Baseline data of the subjects. A total of 80 subjects were selected for eligibility, including 40 subjects in the control group and 40 subjects in the experi-ment group. There were 44 males and 36 females, aged (40±9)years. The gender (male, female), age, education background (primary school education, middle school education, high school education, junior college education, undergraduate education, postgraduate education) were 23, 17, (39±9)years, 1, 3, 9, 16, 9, 2 in subjects of the control group, versus 25, 15, (42±10)years, 0, 8, 6, 11, 14, 1 in subjects of the experiment group, showing no significant difference in the above indicators between the two groups ( χ2=0.20, t=?1.64, Z=?0.10, P>0.05). (2) Anxiety assessment of the subjects. The scores of self-rating Anxiety Scale (SAS) and Hospital Anxiety Scale (HADS) before surgical conversation, after surgical conversation, after surgery were 41±10 and 26±5, 49±11 and 32±3, 40±13 and 15±8 in subjects of the control group, versus 44±9 and 23±3, 66±16 and 28±6, 34±14 and 8±3 in subjects of the experiment group, showing significant differences in the above indicators between the two groups ( FSAS组间=8.83, FSAS时间=40.41, FSAS交互=12.21, FHADS组间=32.42, FHADS时间=321.28, FHADS交互=6.15, P<0.05).

Objective: To investigate the effects of lactoprotein iron chelates on rats with iron deficiency anaemia (IDA), so as to provide insights into developing and utilizing novel iron supplements. Methods: Seventy weaning female SPF-graded rats of the SD strain were randomly divided into the control group (A), model group (B), ferrous sulfate group (C), lactoferrin group (D), lactoferrin iron chelate group (E), Casein oligopeptide iron chelate group (F) and whey protein oligopeptide iron chelate group (G), with 10 rats in each group. The rats in group A were fed with normal diet, and the others were fed with poor iron diet for IDA modeling. The corresponding interventions were given by intragastric administration once a day. The iron ion concentrations of group C, E, F and G were 2.0 mg/kg, and the protein and oligopeptide concentrations of group D, E, F and G were 2 000 mg/kg. Body weight and hemoglobin of rats were measured weekly during 21-day intervention. At the end, peripheral blood samples were collected, and blood routine, iron metabolism and liver function indicators were determined. Results: After the intervention, among blood routine indicators, the rats in group C, E, F and G showed elevated hemoglobin, red blood cell, mean corpuscular volume and hematocrit, and decreased free protoporphyrin and mean corpuscular hemoglobin concentration when compared with the rats in group B (all P<0.05); among iron metabolism indicators, the rats in group C, E and G showed elevated serum ferritin, the rats in group C, E, F and G showed elevated serum iron, the rats in group C, D, E, F and G showed decreased unsaturated iron binding capacity and total iron binding capacity when compared with the rats in group B (all P<0.05); among liver function indicators, the rats in group E and G showed decreased alanine transaminase when compared with the rats in group B (both P<0.05). Conclusions Lactoprotein alone could not completely improve IDA in rats compared with traditional iron supplement (ferrous sulfate). Lactoprotein iron chelate, especially whey protein oligopeptide iron chelate, could significantly improve IDA, iron reserve and liver function damage in rats.

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.

Cervical cancer is a common malignant tumor of female reproductive system. The treatment of cervical cancer is based on surgery and radiotherapy (or concurrent chemoradiation). Lower extremity lymphedema (LEL) is a frequent complication after cervical cancer treatment, which significantly affects the quality of life of patients. Both pelvic surgery and radiation for cervical cancer can lead to LEL. The risk factors for LEL are complicated and involving characteristics regarding patient (age, comorbidities, lifestyle, etc.), tumor [International Federation of gynecology and Obstetrics (FIGO) stage, lymph node metastasis, etc.], and treatment (number of resected lymph nodes, removal of circumflex iliac nodes, adjuvant therapy, etc.). Comprehensive measures are proposed to prevent cervical cancer patients from LEL, and further investigations in terms of effectiveness are warranted.

Objective:To explore the application of mobile augmented reality (mAR) technology in the teaching of neuroanatomy, and to observe its effect on students' academic performance and cognitive load.Methods:By collecting and designing various neuroanatomy multimedia teaching resources (graphics, animations and videos), using augmented reality (AR) marker-based image recognition technology, the multimedia resources were placed at the tags in the traditional book pages to make the books interactive. And various multimedia resources were combined with traditional printed books through mobile devices. Forty students were randomized into the experimental group or the control group. The experimental group was taught with mAR multimedia materials, and the control group adopted traditional teaching methods. After a 6-hour course was completed, all students had a unified test, and the academic performance test and the PAAS(platform-as-a-service) cognitive load scale were used for data collection and analysis. The variance analyses (MANOVA and ANOVA) were used for significance testing.Results:One-way MANOVA test was used to determine the learning effect of mAR on academic performance and cognitive load. The results showed that there was a significant difference between the experimental group and the control group ( P<0.05). The univariate ANOVA test found that the experimental group students who learned neuroanatomy through mAR had better test scores than the control group students. In addition, compared with the control group students, the cognitive load of students in experimental group was significantly reduced, with statistical significance (all P<0.05). Conclusion:Through the teaching practice, we found that using mAR to learn neuroanatomy helps students improve their academic performance while reducing their cognitive load.
