This study explores the diagnosis and treatment of needle knife therapy for ankylosing spondylitis (AS) at middle and advanced stage based on the theory of meridian tendons, from a holistic perspective and syndrome differentiation. The treatment strategy includes "harmonizing yin and yang" to address root causes and "tendons-based release" to harmonize qi and blood, with the "tendons nodule points" as the core acupoint selection criterion. Based on this approach, the study systematically elaborates on two needle knife methods for AS: "governor vessel bone-piercing technique" and "below-the-umbilicus release technique", covering indications, acupoint location, and procedures. Clinical case examples are provided to enrich needle knife therapy guided by the theory of meridian tendons, offering insights for clinical and research work on AS.

Integrating evidence from animal experiments is a critical component of biomedical research, providing essential prior information for in-depth investigations of disease mechanisms and new drug development. Animal models have played an irreplaceable role in simulating human diseases. However, the integration of evidence from animal experiments has faced numerous challenges, including insufficient emphasis, significant heterogeneity in study designs, high publication bias, and discrepancies with clinical research practices. This paper first identifies existing issues in the original research evidence from animal experiments, such as the selection and applicability of animal models, considerations in the design of experimental studies, and factors influencing the translation of animal experimental evidence. It then discusses various methods for integrating this evidence, including systematic review and meta-analysis, overview of systematic review/umbrella review, scoping review, and evidence mapping, while highlighting recent advancements in their application. Finally, the paper addresses the main challenges currently encountered in the integration of evidence from animal experiments and proposes targeted improvement strategies aimed at enhancing the efficiency of translating research outcomes into clinical practice and promoting the advancement of evidence-based medicine. By continuously optimizing original experimental research protocols and evidence integration practices, this work aims to establish a more efficient and scientific environment for the synthesis of evidence from animal experiments, ultimately contributing to clinical trials and human health.

Objective:To understand the relationship between the disease condition of patients with coal-burning-borne endemic arsenic poisoning (abbreviated as coal-burning-borne arsenic poisoning) and serum lipid metabolism indicators.Methods:Using a case-control study method, in the coal-burning-borne arsenic poisoning village of Yuzhang Town, Qianxinan Prefecture, Guizhou Province, 204 patients with arsenic poisoning diagnosed according to the standard of "Diagnosis of Endemic Arsenicosis" (WS/T 211-2015) were included in case group, including 87 males and 117 females, aged(53.37 ± 8.06) years old; and they were divided into mild arsenic poisoning group (71 cases), moderate arsenic poisoning group (59 cases) and severe arsenic poisoning group (74 cases) according to the clinical grading. Another 63 residents were selected into control group in a non-arsenic-exposed village about 12 km away from the diseased village, including 23 males and 40 females, aged (53.78 ± 9.10) years old. A face-to-face questionnaire survey was conducted for each group of people, including basic information such as general demographic characteristics, smoking status, and drinking status; fasting peripheral blood was collected, and an automatic biochemical analyzer was used to detect serum total cholesterol (TC) and triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels.Results:There were significant differences of serum TC [(4.94 ± 1.00), (5.00 ± 0.99), (5.27 ± 0.94), (5.57 ± 1.07) mmol/L], TG [(2.17 ± 0.90), (2.25 ± 1.31), (2.66 ± 1.43), (2.78 ± 1.40) mmol/L], LDL-C [(2.51 ± 0.79), (2.74 ± 0.64), (2.97 ± 0.66), (3.15 ± 0.80) mmol/L], and HDL-C levels [(1.57 ± 0.55), (1.42 ± 0.43), (1.36 ± 0.42), (1.30 ± 0.38) mmol/L] in control group, mild, moderate and severe arsenic poisoning groups ( F = 5.83, 3.64, 9.72, 4.41, P < 0.01 or < 0.05). Among them, the serum TC level in severe arsenic poisoning group, serum TG and LDL-C levels in moderate and severe arsenic poisoning groups were significantly higher than those in control group ( P < 0.05); the serum HDL-C level in moderate and severe arsenic poisoning groups were lower than that in control group ( P < 0.05); the serum TC, TG and LDL-C levels in severe arsenic poisoning group were significantly higher than those in mild arsenic poisoning group ( P < 0.05). After linear trend test, serum TC, TG and LDL-C levels all showed an upward trend with the degree of arsenic poisoning ( Ftrend = 15.77, 10.14, 29.15, P < 0.05), and serum HDL-C level showed a downward trend with the degree of arsenic poisoning ( Ftrend = 12.75, P < 0.05). There were significant differences in the abnormal rates of serum TC, TG and LDL-C levels among control group and mild, moderate and severe arsenic poisoning groups (χ 2 = 21.16, 16.60, 8.29, P < 0.01 or < 0.05). Among them, the serum TC and TG levels abnormal rates in moderate and severe arsenic poisoning groups and serum LDL-C level abnormal rate in severe arsenic poisoning group were higher than those in control group ( P < 0.05), the serum TC, TG and LDL-C levels abnormal rates in severe arsenic poisoning group were higher than those in mild arsenic poisoning group ( P < 0.05). There was no significant difference of the serum HDL-C level abnormal rate among four groups (χ 2 = 2.11 , P > 0.05). The results of trend chisquare analysis showed that the abnormal rates of serum TC, TG and LDL-C levels presented an increasing trend with the degree of arsenic poisoning (χ 2trend = 19.90, 15.25, 7.63, P<0.05). The results of logistic regression analysis showed that the risk of abnormal serum TC level in patients with severe arsenic poisoning was 2.90 times that in control group [odds ratio ( OR) = 2.90, 95% confidence interval ( CI): 1.43 - 5.91], and the risk of abnormal serum LDL-C level in patients with severe arsenic poisoning was 2.87 times that in control group ( OR = 2.87, 95% CI: 1.22 - 6.71). Conclusion:There is a correlation between the disease condition of patients with coal-burning-borne arsenic poisoning and their dyslipidemia.

Objective To improve the awareness of fetal cardiac rhabdomyomas (CRs) and investigate a better model for prenatal diagnosis and treatment through analyzing imaging findings and prognosis.Methods A retrospective study was conducted on 23 cases of CRs which were diagnosed by ultrasound in Obstetrics and Gynecology Hospital of Fudan University from January 2008 to November 2015.General conditions,imaging features,prognosis and follow-up data of the 23 cases were described.Results The average gestational age of the 23 fetuses at diagnosis was (29.8±4.1) (22.4-35.7) weeks.Seventeen out of the 23 gravidas received prenatal multidisciplinary consultation.Among all 23 gravidas,three (13％) were lost to follow-up,12 (52％) decided to terminate the pregnancy,and the other eight (35％) continued to term pregnancy and their babies were followed up for three years.Of these eight cases,two cases received prenatal brain MRI and no tuberous sclerosis complex (TSC) was detected,no CRs was identified during the follow-up,and their physical and mental developments were both normal.One case was diagnosed with suspected subependymal nodules by prenatal brain MRI in our hospital,but the MRI images was normal when scanned in the other hospital,and follow-up data revealed neither CRs nor abnormal physical and mental developments.Four cases did not received prenatal brain MRI,but the MRI images of neonatal brains indicated TSC,besides,follow-up data showed that seizures were observed,physical developments were all normal,but three of the four cases had mental retardation;CRs disappeared in only two of the four cases.One case had neither prenatal nor neonatal MRI,but follow-up data showed that CRs had disappeared and physical and mental developments were both normal.Conclusions Prenatal diagnosis of fetal tuberous sclerosis is crucial to the prognosis of CRs.Prenatal ultrasonography in combination with cranial MRI improves the accuracy of prenatal diagnosis of CRs complicated with TSC and assists in clinical decision-making and prognosis analysis.

BACKGROUND:Cholesterol is closely linked to the occurrence and progression of atherosclerosis. Current approaches to study celular cholesterol dynamics have their own limitations.
OBJECTIVE: To measure the cholesterol efflux rate of RAW 264.7 mouse macrophages by BODIPY-Cholesterol labeling and to explore the effects of extracelular cholesterol and lipopolysaccharide on the cholesterol efflux rate.
METHODS:RAW 264.7 cels were cultured in vitro with DMEM containing 10% fetal bovine serum, and labeled with BODIPY-Cholesterol for 1, 2, 4, 8 hours. Then, the cels were rinsed with serum-free DMEM and inoculated for 6, 12, 24, 48, 96 hours to optimize the labeling time and incubation time. We measured and compared the cholesterol efflux rates after cultured cels were treated with cholesterol, lipopolysaccharide, human sera with high cholesterol or human sera with normal cholesterol.
RESULTS AND CONCLUSION: The best labeling time for BODIPY-Cholesterol was 2-8 hours. Cholesterol efflux rates were gradualy decreased after the cels that were labeled for 2 hours were incubated with increasing concentrations of cholesterol (0.1, 0.5, 2.5 mmol/L,P< 0.01). Treating cels with lipopolysaccharide also decreased the cholesterol efflux rate (P < 0.05). Furthermore, the cholesterol efflux rate was decreased after cels were treated with human sera with high cholesterol (P< 0.05). These findings indicate that BODIPY-Cholesterol can be used to measure celular cholesterol efflux rate and to study the effects of extracelular cholesterol and lipopolysaccharide on the cholesterol efflux rate.

BACKGROUND:B-lymphocytes are an important participant in the immunity system. Currently, magnetic beads and complement methods are mainly used to isolate and purify B-lymphocytes. However, these methods are costly or cause large cel damage and low purity, which need further improvement. OBJECTIVE: To explore the isolation and culture methods of B-lymphocytes from mouse spleen and to study suitable conditions for B-lymphocyte isolation and culture in vitro by using interleukin-4, lipopolysaccharide, CD3 monoclonal antibody or their combination. METHODS:B-lymphocytes from mouse spleen were isolated and randomly divided into seven groups, respectively treated with interleukin-4, CD3 monoclonal antibody, lipopolysaccharide, interleukin-4+CD3, interleukin-4+lipopolysaccharide, CD3+lipopolysaccharide, and no stimulation (control group). Flow cytometry was used to detect the changes in the number and proportion of T-lymphocytes, B lymphocytes, and their subpopulations under different culture conditions. RESULTS AND CONCLUSION:The number of lymphocytes peaked at 3-5 days after addition of interleukin-4. In the lipopolysaccharide group, the number of lymphocytes began to increase at 3 days, and then peaked at 5 days. T-lymphocytes disappeared after addition of CD3 monoclonal antibody, so relatively pure B-lymphocytes could be obtained after 2 days and the number of B-lymphocytes reached the peak at 3 days. The number of mature B-lymphocytes (B220+IgD+) increased significantly after addition of CD3 antibody. In al the conditions we tested, transitional B cel subset (B220+CD93+) disappeared completely after 24 hours of culture. Experimental results indicate that after addition of CD3 monoclonal antibody and interleukin-4, T-lymphocytes can be removed in mouse spleen cels cultured, but mature B-lymphocytes remain to survive and proliferate.
