The concept of harmony between heaven and man is an important concept in TCM. The theory of "harmful hyperactivity and responding inhibition" has been developed and perfected by medical professionals throughout history to explain physiological and pathological changes in humans based on a natural understanding. Guided by the TCM philosophy of "harmful hyperactivity and responding inhibition", it provides guidance for attention deficit hyperactivity disorder (ADHD). Sorting out the complex pathogenesis, it has been found that core pathogenesis of the disease is the excessive damage to the five organs, which leads to the overall state of yin deficiency and yang hyperactivity in the human body. The treatment mainly focuses on regulating the hyperactivity and damage of the organs, restoring the balance of yin and yang, while also taking into account the harm of pathological products. Based on clinical manifestations, the secondary selection of medication for liver and liver hyperactivity and spleen and kidney dysfunction has been determined, while improving the hyperactivity of the external environment, in order to achieve the goal of "tolerance is control", which fully embodies the TCM syndrome differentiation thinking of "unity of heaven and man, holistic concept".

The clinical diagnosis and treatment of urinary tract infection has long faced the challenges of insufficient standardization of diagnosis and treatment pathways,irrational use of antimicrobial drugs and high recurrence rate.How to optimize the hierarchical diagnosis and treatment pathway of urinary tract infection,standardize the use of antimicrobial drugs,and reduce the recurrence rate have always been the focus of clinical attention.There is significant heterogeneity in the existing diagnostic criteria for urinary tract infection,which seriously affects the comparability and evidence integration of clinical and research studies.In order to solve the above problems,a consensus on global multidisciplinary diagnostic criteria for urinary tract infection has been formed by international multidisciplinary experts after three rounds of Delphi method.Breaking through the traditional classification framework,the consensus innovatively established a four-dimensional quantitative scoring system including local symptoms and signs,systemic inflammatory response,quantitative analysis of pyuria and urine culture results,and established a hierarchical standard for stepwise urinary tract diagnosis according to the scoring threshold.Based on the key citations related to the consensus,this paper interprets in detail the basis for the selection of core indicators and the establishment of thresholds for the diagnosis of urinary tract infection in the consensus,and focuses on the key issues and implementation paths of the consensus in localization practice.This consensus provides a unified standard for standardizing the clinical diagnosis and treatment of urinary tract infection,improving the homogeneity of clinical research through standardized diagnostic processes,and promoting the standardization of UTI drug research and development and the rational use of antibiotics and precision.

Background:Colorectal cancer(CRC)is a major cause of cancer death worldwide,and about 30%to 35%of CRC arises from the serrated pathway.Aims:To analyze the clinicopathological and histomorphological characteristics of colorectal superficially serrated adenoma(SuSA),and to investigate the malignant transformation potential of SuSA and further elucidate the role of RSPO2 and RSPO3 in its carcinogenic mechanism.Methods:A total of 169 serrated colorectal lesions confirmed pathologically and fulfilling the inclusion criteria were collected from Shanxi Bethune Hospital from February 2019 to May 2023.Among them,there were 84 cases of SuSA,23 sessile serrated lesions(SSL),32 traditional serrated adenomas(TSA),and 30 hyperplastic polyps(HP).Thirty-nine cases of tubular adenoma(TA),32 CRC,and 33 normal colorectal mucosal tissues were served as controls.The clinicopathological and histomorphological parameters were collected and recorded.Immunohistochemical staining was used to detect the protein expressions of RSPO2,RSPO3,p53,MLH1 and β-catenin.Results:Patients with SuSA were male predominance,with a mean age of 51.89 years.The average diameter of the lesions was 0.20 cm,predominantly located in the left colon and rectum,and frequently complicated with other polyps/adenomas.The histomorphological features of SuSA were as follows:the glandular necks and crypt bases exhibited straight tubular structure with low-grade dysplasia;the superficial layer demonstrated a serrated architecture,with or without dysplasia,and contained a variable number of goblet cells.Immunohistochemically,there were no statistically significant differences in RSPO2,RSPO3,and p53 expressions between SuSA and TSA(all P>0.05).A strong positive correlation was observed between RSPO2 and RSPO3 in colorectal lesions,excluding HP.Expressions of MLH1 and β-catenin showed no statistically significant differences between SuSA and other colorectal lesions(all P>0.05).Conclusions:SuSAs are more common in males,occur mostly in the left colon and rectum,and are often associated with other polyps/adenomas.They might be precursors of KRAS-mutated TSA and microsatellite stable CRC with high malignant potential.RSPO2 and RSPO3 might play an important role in the carcinogenesis of SuSA.

Non-small cell lung cancer(NSCLC)is a highly lethal malignant tumor that poses a serious threat to human health.Traditional methods for tumor diagnosis and treatment have many limitations.However,circulating tumor DNA(ctDNA)detection,a kind of liquid biopsy technology,has gained widespread attention in the field of NSCLC personalized therapy and monitoring due to its non-invasive,convenient,and comprehensive sensitivity.This article will review the latest research progress of ctDNA detection in the clinical diagnosis and treatment of NSCLC in recent years,including its applications in early screening,disease diagnosis,tumor mutation monitoring,treatment efficacy evaluation,and prognosis assessment.

Clinically,polycystic liver disease(PLD)is a rare genetic disease.Most patients have no clinical symptoms,and a few patients with symptomatic PLD complicated by serious complications need to be treated.Liver transplantation is the only radical treatment for patients with symptomatic PLD.However,most patients are not able to receive liver transplantation due to a lack of donors,expensive surgical cost,and high risk.Because of its many advantages such as less trauma,fast recovery,repeatable,high safety and fewer complications,the minimally-invasive interventional techniques,represented by percutaneous cyst sclerotherapy and transcatheter arterial embolization,have been successfully employed for the treatment of symptomatic PLD in recent years,moreover,its clinical effect has been recognized by both doctors and patients.Therefore,as it can improve the local symptoms and the quality of life of patients,the therapy using minimally-invasive interventional technique will become the development direction for the treatment of symptomatic PLD.This article aims to make a comprehensive review concerning the principle,mechanism,guiding mode,clinical application,advantages and disadvantages,and related complications of percutaneous cyst sclerotherapy and transcatheter arterial embolization therapy in the treatment of symptomatic PLD.

BACKGROUND:Ankylosing spondylitis is a chronic inflammatory disease with chronic rheumatic immunity.Soft tissue ossification and fusion and spinal stiffness can cause biomechanical changes. OBJECTIVE:To reconstruct the lumbar-sacral intervertebral disc in ankylosing spondylitis patients with lumbar kyphosis by finite element analysis,and to study the range of motion of each segment of T11-S1 and the biomechanical characteristics of annulus fibrosus and nucleus pulposus. METHODS:The imaging data were obtained from an ankylosing spondylitis patient with lumbar kyphosis.The original CT image data of continuously scanned spine were imported into Mimics 21.0 in DICOM format,and T11-S1 was reconstructed respectively.The established model was imported into 3-Matic software in the format of"Stl"to reconstruct the intervertebral disc,and the fibrous intervertebral disc model was obtained.The improved model was further imported into Hypermesh software,and the vertebra,nucleus pulposus,annulus fibrosus and ligament were mesh-divided.After the material properties were given,the model was imported into ABAQUS software to observe the range of motion of each vertebral body in seven different working conditions of T11-S1,and analyze the biomechanical characteristics of each segment of annulus fibrosus and nucleus pulposus. RESULTS AND CONCLUSION:(1)The range of motion of L1 vertebrae was higher than that of other vertebrae under six different working conditions:extension,forward flexion,rotation(left and right),and lateral flexion(left and right).The maximum range of motion was 2.18° during L1 vertebral flexion,and the minimum range of motion was 0.12° during L5 vertebral extension.(2)The annular fiber flexion at L2-L3 segments was greater than the extension(P<0.05),and the annular fiber flexion at L3-L4 and L4-L5 segments was less than the extension(P<0.05).The left rotation of L1-L2 annular fibers was greater than the right rotation(P<0.05).The left flexion of the annulus was greater than the right flexion in L1-L2,L2-L3,L3-L4,L4-L5 and L5-S1 segments(P<0.05).(3)The nucleus pulposus stresses of T11-L12,L1-L2,L2-L3,L3-L4 and L4-L5 segments in forward flexion were greater than in extension(P<0.05).The left rotation of T12-L1 and L3-L4 segments was smaller than the right rotation(P<0.05),and that of T11-T12,L1-L2,and L2-L3 segments was larger than the right rotation(P<0.05).The left flexion was larger than the right flexion in the T11-S1 segment.(4)It is concluded that in ankylosing spondylitis patients with lumbar kyphosis,the minimum range of motion of the vertebral body is located at the L5 vertebral body in extension.To prevent fractures,it is recommended to avoid exercise in the extension position.During the onset of lumbar kyphosis in patients with ankylosing spondylitis,the maximum stress of the annulus fibrosus and nucleus pulposus is located in the L1-L2 segment,which is fixed and will not alter with the change of body position.The late surgical treatment and correction of deformity should focus on releasing the pressure of the annulus fibrosus and nucleus pulposus in this segment to avoid the rupture of the annulus fibrosus and the injury of the nucleus pulposus.

Objective To investigate the risk factors of internal fixation failure in proximal femoral nail antirotation (PFNA) for treating intertrochanteric fracture.Methods The imageological data of 179 patients with intertrochanteric fracture receiving PFNA internal fixation were analyzed retrospectively.The univariate analysis was adopted to analyze the influence of the gender,degree of osteoporosis,AO/OTA fracture type,top apex distance (TAD),postoperative coxa vara,lateral wall state,fracture reduction situation and screw blade position on the internal fixation failure.The logistic regression model was constructed.The risk factors of internal fixation failure were analyzed.Results Among 179 patients,the internal fixation failure occurred in 16 cases.The univariate analysis showed the AO/OTA fracture type,TAD,postoperative coxa vara,lateral wall state,fracture reduction effect and screw blade location were related with the internal fixation failure (P<0.05).The logistic regression analysis prompted that postoperative coxa vara (OR=6.97,95％CI:2.24-21.68,P=0.001) and the lateral wall breakage (OR=3.08,95％CI:1.03-9.22,P=0.045) were the risk factors of internal fixation failure in femoral intertrochanteric fracture.Conclusion Coxa vara and lateral wall breakage are the risk factors of internal fixation failure in PENA for treating femoral intertrochanteric fracture,and the operation reduction should avoid the coxa vara appearance.

Objective:To evaluate the 1-year postoperative efficacy and nutritional indicators of single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) in obese patients.Methods:This retrospective observational study included patients with a body mass index (BMI) of ≥40.0 kg/m 2 regardless of other related metabolic diseases and patients with severe type 2 diabetes and a BMI between 27.5 and 40.0 kg/m 2. The clinical data of 66 obese patients who underwent SADI-S at the Bariatric and Metabolic Surgery Department of China-Japan Union Hospital of Jilin University from November 2018 to May 2022 were collected, including 53 cases of da Vinci robotic surgery and 13 cases of laparoscopic surgery. The patients comprised 38 men and 28 women with a median age of 35 (18–61) years and a mean preoperative BMI of 42.93 ± 6.82 kg/m 2. A total of 38 patients had type 2 diabetes, and 46 had hyperuricemia, 45 had hypertension, 35 had hyperlipidemia, 12 had hypercholesterolemia, and 12 had a high low-density lipoprotein (LDL) level. The main observation indicators were (1) intraoperative and postoperative conditions; (2) weight loss outcomes, including body weight, BMI, excess body weight loss (%EWL), and total body weight loss (%TWL) at 3, 6, and 12 months after surgery; (3) effects of treatment on metabolic disease; and (4) changes in nutrient indicators. Results:(1) Intraoperative and postoperative conditions: All patients successfully underwent SADI-S with neither conversion to laparotomy nor death. Four (6.1%) patients developed postoperative complications, and all of them recovered and were discharged after conservative or surgical treatment. (2) Weight loss outcomes: %EWL at 3, 6, and 12 months after surgery was 62.07 ± 26.56, 85.93 ± 27.92, and 106.65 ± 29.65, respectively, and %TWL was 22.67 ± 4.94, 32.10 ± 5.18, and 40.56 ± 7.89, respectively. Body weight and BMI 3 to 12 months after surgery were significantly lower than those before surgery (all P < 0.001). (3) Effect of treatment on metabolic disease: 3 to 12 months after surgery, fasting blood sugar, HbA1c, uric acid, systolic blood pressure, diastolic blood pressure, triglycerides, total cholesterol, LDL, and other indicators were significantly lower than those before surgery (all P < 0.05). Twelve months after surgery, the remission rates of diabetes, hyperuricemia, hypertension, hypertriglyceridemia, hypercholesterolemia, and high LDL were 100% (38/38), 65.2% (30/46), 62.2% (28/45), 94.3% (33/35), 100% (12/12), and 100% (12/12), respectively. (4) Changes in nutrient indicators: Compared with the preoperative nutrient levels, the hemoglobin and hematocrit levels were lower at 3 to 12 months after surgery, the total protein level was lower at 6 to 12 months after surgery, the albumin level was lower at 6 months after surgery, and the ferritin level was lower at 3 months after surgery. The differences were statistically significant (all P < 0.05). The incidence of anemia was 6.1% (4/66), hypoalbuminemia was 4.5% (3/66), and ferritin deficiency was 4.5% (3/66), all of which were improved or normalized through conservative treatment. Twelve months after surgery, 30 (45.5%) patients had vitamin A deficiency, 17 (25.8%) had vitamin E deficiency, 11 (16.7%) had folic acid deficiency, 2 had potassium deficiency (3.0%), 3 (4.5%) had calcium deficiency, 2 (3.0%) had magnesium deficiency, 9 (13.6%) had iron deficiency, and 16 (24.2%) had zinc deficiency. However, no relevant clinical symptoms occurred. Conclusions:SADI-S has a very significant effect on weight loss and alleviation of metabolic diseases. Nutrient deficiencies after SADI-S mainly involve vitamin A, vitamin E, zinc, and folic acid. The long-term efficacy and safety of SADI-S still need further follow-up observation.
