Research progress on the manifestations and prognosis of neonatal lupus erythematosus in various systems / 中国当代儿科杂志

Neonatal lupus erythematosus (NLE) is caused by the transmission of maternal anti-Ro/SSA antibodies, anti-La/SSB antibodies, and other autoantibodies to the fetus through the placenta. Usually, with the disappearance of autoantibodies in the children's body, abnormal changes in the mucocutaneous, blood system, and digestive system can spontaneously subside, but the damage to various systems caused by autoantibodies may persist for a long time. This article provides a comprehensive review of the manifestations and prognosis of NLE in various systems, including mucocutaneous, blood system, circulatory system, nervous system, digestive system, respiratory system, aiming to provide reference for clinical work.

Progress on study of factors influencing the prognosis and complications of surgery for discoid meniscus injury in children / 中国骨伤

The discoid meniscus is a common congenital meniscal malformation that is prevalent mainly in Asians and often occurs in the lateral discoid meniscus. Patients with asymptomatic discoid meniscus are usually treated by conservative methods such as observation and injury avoidance, while patients with symptoms and tears need to be treated surgically. Arthroscopic saucerization combined with partial meniscectomy and meniscus repair is the most common surgical approach., and early to mid-term reports are good. The prognostic factors are the patient's age at surgery、follow-up time and type of surgery. Some patients experience complications such as prolonged postoperative knee pain, early osteoarthritis, retears and Osteochondritis dissecans. The incidence of prolonged postoperative knee pain was higher and the incidence of Osteochondritis dissecans was the lowest. Retears of the lateral meniscus is the main reason for reoperation.

The Uptake and Distribution Evidence of Nano- and Microplastics in vivo after a Single High Dose of Oral Exposure / 生物医学与环境科学（英文）

OBJECTIVE@#Tissue uptake and distribution of nano-/microplastics was studied at a single high dose by gavage in vivo.@*METHODS@#Fluorescent microspheres (100 nm, 3 μm, and 10 μm) were given once at a dose of 200 mg/(kg∙body weight). The fluorescence intensity (FI) in observed organs was measured using the IVIS Spectrum at 0.5, 1, 2, and 4 h after administration. Histopathology was performed to corroborate these findings.@*RESULTS@#In the 100 nm group, the FI of the stomach and small intestine were highest at 0.5 h, and the FI of the large intestine, excrement, lung, kidney, liver, and skeletal muscles were highest at 4 h compared with the control group ( P < 0.05). In the 3 μm group, the FI only increased in the lung at 2 h ( P < 0.05). In the 10 μm group, the FI increased in the large intestine and excrement at 2 h, and in the kidney at 4 h ( P < 0.05). The presence of nano-/microplastics in tissues was further verified by histopathology. The peak time of nanoplastic absorption in blood was confirmed.@*CONCLUSION@#Nanoplastics translocated rapidly to observed organs/tissues through blood circulation; however, only small amounts of MPs could penetrate the organs.

Artesunate Combined with Other Medications and Action Mechanism： A Review / 中国实验方剂学杂志

A sesquiterpene natural substance called artemisinin was discovered in Artemisia annua. One of its derivatives， artesunate （ART）， has the properties of economy， immediate effect， low toxicity， and good tolerance. Since it has a quick and powerful killing effect on plasmodium in the erythrocyte phase and can quickly handle clinical seizure and symptoms， it is currently mostly utilized to treat cerebral malaria and other severe instances of malaria. In addition， it has antitumor， antivirus， anti-hepatic fibrosis， anti-inflammatory， antibacterial， hepatocyte protection， immunological modulation， and other pharmacological properties and can inhibit cell proliferation， induce cell apoptosis， and reduce the incidence of sepsis. In many countries， artemisinin-based combination therapies （ACTs）， such as artemether-benflumetol， artesunate-amodiaquine， and artemether-lumefantrine， are the first-line treatments for malaria. Recent research on artesunate by Chinese and international scholars has revealed that compared with monotherapy， artesunate combination therapy offers more benefits in terms of improving pharmacological effects， shortening the duration of medicine， and minimizing adverse effects. Through systematic retrieval of Web of Science Core Collection and integration through CiteSpace （6.2.1） software， this article reviewed the mechanism of artesunate combined with other medications with regard to antimalarial， antitumor， antibacterial， and antiviral features in the previous five years， so as to provide some theoretical basis for rational development and utilization of ART and new drug research and development.

Analysis of 9 cases of drug induced hypersensitivity syndrome related hemophagocytic lymphohistiocytosis / 中华儿科杂志

Objective: To analyze the clinical features,treatment and prognosis of drug induced hypersensitivity syndrome related hemophagocytic lymphohistiocytosis (DIHS-HLH). Methods: This was a retrospective case study. Clinical characteristics, laboratory results, treatment and prognosis of 9 patients diagnosed with DIHS-HLH in Beijing Children's hospital between January 2020 and December 2022 were summarized. Kaplan-Meier survival analysis was used to calculate the overall survival rate. Results: Among all 9 cases, there were 6 males and 3 females, with the age ranged from 0.8 to 3.1 years. All patients had fever, rash, hepatomegaly and multiple lymph node enlargement. Other manifestations included splenomegaly (4 cases), pulmonary imaging abnormalities (6 cases), central nervous system symptoms (3 cases), and watery diarrhea (3 cases). Most patients showed high levels of soluble-CD25 (8 cases), hepatic dysfunction (7 cases) and hyperferritinemia (7 cases). Other laboratory abnormalities included hemophagocytosis in bone marrow (5 cases), hypofibrinogenemia (3 cases) and hypertriglyceridemia (2 cases). Ascending levels of interleukin (IL) 5, IL-8 and interferon-γ (IFN-γ) were detected in more than 6 patients. All patients received high dose intravenous immunoglobulin, corticosteroid and ruxolitinib, among which 4 patients were also treated with high dose methylprednisolone, 2 patients with etoposide and 2 patients with cyclosporin A. After following up for 0.2-38.6 months, 7 patients survived, and the 1-year overall survival rate was (78±14)%. Two patients who had no response to high dose immunoglobulin, methylprednisolone 2 mg/(kg·d) and ruxolitinib died. Watery diarrhea, increased levels of IL-5 and IL-8 and decreased IgM were more frequently in patients who did not survive. Conclusions: For children with fever, rash and a suspicious medication history, when complicated with hepatomegaly, impaired liver function and high levels of IL-5 and IL-8, DIHS-HLH should be considered. Once diagnosed with DIHS-HLH, suspicious drugs should be stopped immediately, and high dose intravenous immunoglobulin, corticosteroid and ruxolitinib could be used to control disease.

Ethical Problems and Countermeasures in Rehabilitation Intervention for Patients with lymphedema after Breast Cancer Operation / 中国医学伦理学

In order to explore the medical and social problems related to postoperative lymphedema in breast cancer patients, improve the compliance of rehabilitation treatment and help patients return to society. The self-designed questionnaire was used to investigate 76 patients who met the criteria of lymphedema after breast cancer and refused or failed to adhere to rehabilitation threapy. According to the relevant measurement scale theory and method, the computer-aided software was used to analyze the data to find out the problem and analyze the cause. The prominent problems of poor compliance in patients with breast cancer after operation were successively: subjective factors, objective factors, family social and ethical factors, multidisciplinary factors, hospital management and policy issues. For the above ethical problems, we should adopt positive coping strategies to increase the compliance of patients and improve their quality of life.

Significance of Tim-3 and Its Ligand Galectin-9 in Th1/Th2 Imbalance in Patients with Multiple Myeloma / 中国实验血液学杂志

OBJECTIVE@#To investigate the significance of Tim-3 and Galectin-9 in Th1/Th2 imbalance in patients with multiple myeloma (MM).@*METHODS@#55 newly diagnosed MM patients and 20 healthy controls were included. Flow cytometry was used to detect the expression of Tim-3 on CD4+T cells, the proportion of Th1, Th2, Tim-3+Th1 and Tim-3+Th2 cells in peripheral blood. ELISA was used to detect the levels of cytokines IFN-γ and IL-4 in serum, and PCR was used to detect the level of Galectin-9 mRNA. Then the correlations between Galectin-9 mRNA expression and Th-cell subsets and related cytokine levels, as well as the relationship between Tim-3+Th1/Tim-3+Th2 ratio and corresponding clinical features were analyzed.@*RESULTS@#Compared with the control group, the expression of Tim-3 on CD4+T cells in peripheral blood of MM patients was significantly increased (P<0.05), the proportions of Tim-3+Th1 cells, Tim-3+Th2 cells and Tim-3+Th1/Tim-3+Th2 ratio in MM patients were also increased (P<0.05), while the proportion of Th1 cells and Th1/Th2 ratio in MM patients were significantly decreased (P<0.05). The level of cytokine IFN-γ and IFN-γ/IL-4 ratio in MM patients were significantly decreased (P<0.05), while the level of cytokine IL-4 was increased (P<0.05). The mRNA levels of Galectin-9 in MM patients were significantly increased (P<0.05). The levels of Galectin-9 mRNA were positively correlated with Tim-3+CD4+T cells (r=0.663), Tim-3+Th2 cells (r=0.492) and IL-4 (r=0.470), while negatively correlated with IFN-γ (r=-0.593). The ratios of Tim-3+Th1/Tim-3+Th2 in MM patients were positively correlated with ISS stage (r=0.511), osteolytic damage (r=0.556) and chromosome abnormality (r=0.632).@*CONCLUSION@#These results suggest that Tim-3 and Galectin-9 are involved in Th1/Th2 imbalance in MM patients, and the high ratio of Tim-3+Th1/Tim-3+Th2 is associated with poor clinical prognosis.

Alterations of β-γ coupling of scalp electroencephalography during epilepsy / 生物医学工程学杂志

Uncovering the alterations of neural interactions within the brain during epilepsy is important for the clinical diagnosis and treatment. Previous studies have shown that the phase-amplitude coupling (PAC) can be used as a potential biomarker for locating epileptic zones and characterizing the transition of epileptic phases. However, in contrast to the θ-γ coupling widely investigated in epilepsy, few studies have paid attention to the β-γ coupling, as well as its potential applications. In the current study, we use the modulation index (MI) to calculate the scalp electroencephalography (EEG)-based β-γ coupling and investigate the corresponding changes during different epileptic phases. The results show that the β-γ coupling of each brain region changes with the evolution of epilepsy, and in several brain regions, the β-γ coupling decreases during the ictal period but increases in the post-ictal period, where the differences are statistically significant. Moreover, the alterations of β-γ coupling between different brain regions can also be observed, and the strength of β-γ coupling increases in the post-ictal period, where the differences are also significant. Taken together, these findings not only contribute to understanding neural interactions within the brain during the evolution of epilepsy, but also provide a new insight into the clinical treatment.

Aurora A Kinase Plays a Key Role in Mitosis Skip during Senescence Induced by Ionizing Radiation / 生物医学与环境科学（英文）

OBJECTIVE@#To investigate the fate and underlying mechanisms of G2 phase arrest in cancer cells elicited by ionizing radiation (IR).@*METHODS@#Human melanoma A375 and 92-1 cells were treated with X-rays radiation or Aurora A inhibitor MLN8237 (MLN) and/or p21 depletion by small interfering RNA (siRNA). Cell cycle distribution was determined using flow cytometry and a fluorescent ubiquitin-based cell cycle indicator (FUCCI) system combined with histone H3 phosphorylation at Ser10 (pS10 H3) detection. Senescence was assessed using senescence-associated-β-galactosidase (SA-β-Gal), Ki67, and γH2AX staining. Protein expression levels were determined using western blotting.@*RESULTS@#Tumor cells suffered severe DNA damage and underwent G2 arrest after IR treatment. The damaged cells did not successfully enter M phase nor were they stably blocked at G2 phase but underwent mitotic skipping and entered G1 phase as tetraploid cells, ultimately leading to senescence in G1. During this process, the p53/p21 pathway is hyperactivated. Accompanying p21 accumulation, Aurora A kinase levels declined sharply. MLN treatment confirmed that Aurora A kinase activity is essential for mitosis skipping and senescence induction.@*CONCLUSION@#Persistent p21 activation during IR-induced G2 phase blockade drives Aurora A kinase degradation, leading to senescence via mitotic skipping.

Effect of down-regulation of let-7c/g on triggering a double-negative feedback loop and promoting restenosis / 中华医学杂志(英文版)

BACKGROUND@#Excessive proliferation and migration of vascular smooth muscle cells (VSMCs) are the main causes of restenosis (RS) in diabetic lower extremity arterial disease (LEAD). However, the relevant pathogenic mechanisms are poorly understood.@*METHODS@#In this study, we introduced a "two-step injury protocol" rat RS model, which started with the induction of atherosclerosis (AS) and was followed by percutaneous transluminal angioplasty (PTA). Hematoxylin-eosin (HE) staining and immunohistochemistry staining were used to verify the form of RS. Two-step transfection was performed, with the first transfection of Lin28a followed by a second transfection of let-7c and let-7g, to explore the possible mechanism by which Lin28a exerted effects. 5-ethynyl-2΄-deoxyuridine (EdU) and Transwell assay were performed to evaluate the ability of proliferation and migration of VSMCs. Western blotting and quantitative real-time polymerase chain reaction (qRT-PCR) were performed to detect the expression of Lin28a protein and let-7 family members.@*RESULTS@#Using a combination of in vitro and in vivo experiments, we discovered that let-7c, let-7g, and microRNA98 (miR98) were downstream targets of Lin28a. More importantly, decreased expression of let-7c/let-7g increased Lin28a, leading to further inhibition of let-7c/let-7g. We also found an increased level of let-7d in the RS pathological condition, suggesting that it may function as a protective regulator of the Lin28a/let-7 loop by inhibiting the proliferation and migration of VSMCs.@*CONCLUSION@#These findings indicated the presence of a double-negative feedback loop consisting of Lin28a and let-7c/let-7g, which may be responsible for the vicious behavior of VSMCs in RS.

Efficacy of targeted drugs for metastatic non-clear cell renal cell carcinoma:a Meta-analysis / 现代泌尿外科杂志

【Objective】 To systematically evaluate the efficacy and safety of targeted drugs in the treatment of metastatic non-clear cell renal cell carcinoma (nccRCC) and to provide guidance for clinical treatment. 【Methods】 All observational studies and randomized controlled trials (RCTs) of nccRCC treated with targeted drugs were retrieved from the PubMed, Embase, the Cochrane Library and Web of Science. Three independent investigators screened the literature, extracted data and evaluated the quality of literature. The RCTs were evaluated using the Cochrane Handbook. One research with insufficient outcome data (follow-up bias) was assessed as high risk, and the other studies showed low or uncertain risk. The non-RCTs were evaluated with the JBI Quality Assessment Tool, and all studies displayed a low risk of bias. The data were analyzed with Stata 17.0 software. 【Results】 A total of 16 studies involving 989 patients were included. Meta-analysis showed that the objective response rate (ORR) was 12.6% (95%CI:8.1%-17.9%), the total disease control rate (DCR) was 65.3% (95%CI:58.3%-72.1%), the total median progression-free survival (PFS) was 5.80 (95%CI:4.69-6.91) months, and the median overall survival (OS) was 15.93 (95%CI:12.17-19.68) months. In subgroup analysis, the total ORR of patients with metastatic nccRCC treated with sunitinib and cabozantinib were 11.7% (95%CI:6.5%-18.0%) and 17.2% (95%CI:8.4%-28.2%), respectively. The total ORR of patients with papillary renal cell carcinoma was 9.1% (95%CI:2.4%-18.9%). 【Conclusion】 Targeted drugs have a significant effect on patients with metastatic nccRCC, but adverse reactions may occur. Targeted drugs have poor effects on metastatic papillary renal cell carcinoma, and cabozantinib may have greater survival benefits.

Follow-up of 2 to 20 months after discharge showed no internal mammary artery occlusion and 4 radial artery occlusions; no major adverse cardiovascular and cerebrovascular event (MACCE) occurred, and the survival rate was 100%. There was no significant difference in the above perioperative complications and follow-up endpoints between the two age groups.@*CONCLUSIONS@#By adjusting the order of bypass anastomosis and optimizing the preoperative evaluation method, radial artery combined with internal mammary artery can obtain better outcome early in TAR, and can be safely and reliably applied to elderly patients.

Research progress on long-term developmental outcomes of offspring of pregnant women with systemic lupus erythematosus / 中国当代儿科杂志

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease that affects multiple organs and systems. It is more common in women of childbearing age. Compared with the general population, pregnant women with SLE are at a significantly increased risk of adverse perinatal outcomes such as preterm birth and intrauterine growth restriction. In addition, the offspring of SLE patients may also be adversely affected by in utero exposure to maternal autoantibodies, cytokines, and drugs. This article summarizes the long-term developmental outcomes of offspring of pregnant women with SLE in terms of the blood system, circulatory system, nervous system, and immune system.

Analysis of teaching difficulties in the chapter of antigen in Medical Immunology and teaching strategy / 细胞与分子免疫学杂志

The concept of "ntigen"is a relative one. The narrow concept of it condenses the process of activation of adaptive immune response and re-recognition of the same antigen, revealing the protective mechanism of vaccines with great significance for research and development of vaccines. However, the narrow concept involves adaptive immune system members: B cells, T cells and their effector products, which is difficult for beginners to understand the inherent meaning. Meanwhile, antigen classification fully summarizes the immune response process, so a variety of classification approach increases the difficulty in learning. Our teaching team analyzes the difficulties of this chapter in depth, and we implements the strategy that takes antibody structure and function as the breakthrough point and simplified adaptive immune response process as the core in teaching. A mind map that includes the main contents of this chapter is made during the process, which promotes the effectiveness of classroom teaching greatly.

Effect of Gualou Xiebai Decoction on pulmonary fibrosis in rats based on pyroptosis pathway / 中国中药杂志

This study investigated the effect of Gualou Xiebai Decoction on rats with bleomycin-induced pulmonary fibrosis. The rats were randomly divided into a control group, a model group, a low-dose Gualou Xiebai Decoction group(2.4 g·kg~(-1)), a high-dose Gualou Xiebai Decoction group(4.8 g·kg~(-1)), and pirfenidone group(150 mg·kg~(-1)). The model of pulmonary fibrosis was established by intratracheal instillation of bleomycin in all groups, except the control group. Since the second day of modeling, the corresponding drugs were given to rats by intragastric administration, once a day for 14 d and 28 d. The hematoxylin-eosin(HE) staining was used to evaluate the degree of inflammatory injury in lung tissues. The immunofluorescence staining was used to detect the expression of CD68 and CD163 in lung tissues of rats. The levels of tumor necrosis factor-α(TNF-α) and interleukin-10(IL-10) in serum and brochoalveolar lavage fluid(BALF) were detected by enzyme-linked immunosorbent assay(ELISA). The expression of pyroptosis-related genes in lung tissues of rats was detected by qRT-PCR. The results of HE staining and immunofluorescence staining showed that the lung tissue structure was normal in the control group. In addition, there were alveolar collapse or even closure in lung tissues of rats in the model group, with obvious inflammatory cell infiltration, and the expression of CD68 and CD163 was significantly up-regulated. As compared with the model group, the lung tissue structure of rats in the Gualou Xiebai Decoction groups was significantly improved, with alleviated inflammation, and the expression of CD68 and CD163 was decreased. As compared with the control group, the level of TNF-α in serum and BALF of rats in the model group was significantly increased(P<0.01), the mRNA expression levels of alpha smooth muscle actin(α-SMA), collagen type Ⅰ alpha 1 chain(Col1a1), caspase-1, IL-1β, IL-18, gasdermin D(Gsdmd), and NOD-like receptor thermal protein domain associated protein 3(NLRP3) in lung tissues were significantly increased(P<0.05, P<0.01), and the mRNA expression level of E-cadherin was significantly decreased(P<0.01). As compared with the model group, the level of TNF-α in serum and BALF was significantly down-regulated in the high-dose Gualou Xiebai Decoction group(P<0.05, P<0.01), and that of IL-10 was up-regulated(P<0.05, P<0.01). The mRNA expression levels of α-SMA, Col1a1, caspase-1, IL-18, Gsdmd, NLRP3 and IL-1β in lung tissues were significantly decreased(P<0.05, P<0.01) in the high-dose Gualou Xiebai Decoction group, and the mRNA expression level of E-cadherin was significantly increased(P<0.05, P<0.01). In conclusion, Gualou Xiebai Decoction can down-regulate the levels of inflammatory factors and related genes and effectively mitigate pulmonary fibrosis by regulating the pyroptosis pathways.

Obesity is positively Associated with Depression in Older Adults: Role of Systemic Inflammation / 生物医学与环境科学（英文）

OBJECTIVE@#We aimed to explore the association between obesity and depression and the role of systemic inflammation in older adults.@*METHODS@#Adults ≥ 65 years old ( n = 1,973) were interviewed at baseline in 2018 and 1,459 were followed up in 2021. General and abdominal obesity were assessed, and serum C-reactive protein (CRP) levels were measured at baseline. Depression status was assessed at baseline and at follow-up. Logistic regression was used to analyze the relationship between obesity and the incidence of depression and worsening of depressive symptoms, as well as the relationship between obesity and CRP levels. The associations of CRP levels with the geriatric depression scale, as well as with its three dimensions, were investigated using multiple linear regressions.@*RESULTS@#General obesity was associated with worsening depression symptoms and incident depression, with an odds ratio ( OR) [95% confidence interval ( CI)] of 1.53 (1.13-2.12) and 1.80 (1.23-2.63), especially among old male subjects, with OR (95% CI) of 2.12 (1.25-3.58) and 2.24 (1.22-4.11), respectively; however, no significant relationship was observed between abdominal obesity and depression. In addition, general obesity was associated with high levels of CRP, with OR (95% CI) of 2.58 (1.75-3.81), especially in subjects free of depression at baseline, with OR (95% CI) of 3.15 (1.97-5.04), and CRP levels were positively correlated with a score of specific dimension (life satisfaction) of depression, P < 0.05.@*CONCLUSION@#General obesity, rather than abdominal obesity, was associated with worsening depressive symptoms and incident depression, which can be partly explained by the systemic inflammatory response, and the impact of obesity on depression should be taken more seriously in the older male population.

Diabetes mellitus and adverse outcomes after carotid endarterectomy: A systematic review and meta-analysis / 中华医学杂志(英文版)

BACKGROUND@#There is still uncertainty regarding whether diabetes mellitus (DM) can adversely affect patients undergoing carotid endarterectomy (CEA) for carotid stenosis. The aim of the study was to assess the adverse impact of DM on patients with carotid stenosis treated by CEA.@*METHODS@#Eligible studies published between 1 January 2000 and 30 March 2023 were selected from the PubMed, EMBASE, Web of Science, CENTRAL, and ClinicalTrials databases. The short-term and long-term outcomes of major adverse events (MAEs), death, stroke, the composite outcomes of death/stroke, and myocardial infarction (MI) were collected to calculate the pooled effect sizes (ESs), 95% confidence intervals (CIs), and prevalence of adverse outcomes. Subgroup analysis by asymptomatic/symptomatic carotid stenosis and insulin/noninsulin-dependent DM was performed.@*RESULTS@#A total of 19 studies (n = 122,003) were included. Regarding the short-term outcomes, DM was associated with increased risks of MAEs (ES = 1.52, 95% CI: [1.15-2.01], prevalence = 5.1%), death/stroke (ES = 1.61, 95% CI: [1.13-2.28], prevalence = 2.3%), stroke (ES = 1.55, 95% CI: [1.16-1.55], prevalence = 3.5%), death (ES = 1.70, 95% CI: [1.25-2.31], prevalence =1.2%), and MI (ES = 1.52, 95% CI: [1.15-2.01], prevalence = 1.4%). DM was associated with increased risks of long-term MAEs (ES = 1.24, 95% CI: [1.04-1.49], prevalence = 12.2%). In the subgroup analysis, DM was associated with an increased risk of short-term MAEs, death/stroke, stroke, and MI in asymptomatic patients undergoing CEA and with only short-term MAEs in the symptomatic patients. Both insulin- and noninsulin-dependent DM patients had an increased risk of short-term and long-term MAEs, and insulin-dependent DM was also associated with the short-term risk of death/stroke, death, and MI.@*CONCLUSIONS@#In patients with carotid stenosis treated by CEA, DM is associated with short-term and long-term MAEs. DM may have a greater impact on adverse outcomes in asymptomatic patients after CEA. Insulin-dependent DM may have a more significant impact on post-CEA adverse outcomes than noninsulin-dependent DM. Whether DM management could reduce the risk of adverse outcomes after CEA requires further investigation.

ZHANG Lei's Experience in Treating Scleroderma from “Extraordinary Pathogens Entering Collaterals” / 中医杂志

@#This paper summarized professor ZHANG Lei′s experience in treating scleroderma from “extraordinary pathogens entering collaterals”. The basic pathogenesis of scleroderma is “extraordinary pathogens entering the collaterals”， and extraordinary pathogens can be divided into external and internal categories. External extraordinary pathogens are mostly exogenous wind， cold and damp pathogens， and the pathogenesis is wind， cold and damp invading skin stria and retaining collaterals. Most of the endogenous extraordinary pathogens are turbid phlegm and blood stasis， and the pathogenesis is endogenous phlegm and stasis leaving the channels and overflowing the collaterals， and blocking the collaterals. Blocked by extraordinary pathogens for a long time， the long illness will lead to deficiency and develop into a syndrome of collaterals excess and channels deficiency. Therefore， professor ZHANG creats Tengluo Beverage （藤络饮） as the basic formula to unblock collaterals and dispel pathogens， and recommends to add or subtract it according to the different syndrome and pathogenic characteristics of the edema stage， sclerosis stage， and atrophy stage. In the edema stage， it is advised to expel wind， remove dampness and unblock the collaterals， while in the sclerosis stage， the method of dissolving phlegm， expelling stasis and unblocking collaterals should be used； in the atrophic stage， it is suggested to differentiate the deficiency of qi， blood， yin and yang， and eliminate extraordinary pathogens on the basis of reinforcing healthy qi .

Current application and limitations of augmented reality in the stomatology / 中华口腔医学杂志

Computer-assisted technology are gradually integrated into dental education and clinical treatment. As a cutting-edge technology in computer-aided medicine, augmented reality can not only be used as an aid to dental education by presenting three-dimensional scenes for teaching demonstration and experimental skills training, but also can superimpose virtual image information of patients onto real lesion areas for real-time feedback and intraoperative navigation. This review explores the current applications and limitations of augmented reality in dentistry to provide a reference for future research.
