AIM: To compare the changes in corneal epithelial thickness(CET)after small incision lenticule extraction(SMILE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK).METHODS: A total of 187 patients(187 eyes)who underwent either SMILE or FS-LASIK at Urumqi Aier Eye Hospital between December 2022 and November 2023 were collected. The patients were divided into SMILE group and FS-LASIK group according to surgical methods. The CET of the patients was measured by optical coherence tomography(OCT)system before surgery and at 1 wk, 1, 3, and 6 mo postoperatively.RESULTS: Changes in corneal epithelial thickness(△CET)in the central, paracentral, and mid-peripheral regions were compared at 6 mo postoperatively. The SMILE group was characterized by the most significant thickening in the central area and the least thickening in the mid-peripheral area; while the FS-LASIK group was characterized by the most significant thickening in the paracentral area and the least thickening in the mid-peripheral region. At 1 wk, 1, 3, and 6 mo postoperatively, within the 0-7 mm corneal area, the △CET for both the SMILE and FS-LASIK groups was correlated with the preoperative spherical equivalent.CONCLUSION: Within 6 mo postoperatively, both SMILE and FS-LASIK showed a similar trend in epithelial thickening but with distinct characteristics. The change in corneal epithelial thickness for both procedures was positively correlated with the preoperative diopter.

This article summarizes Academician WANG Yongyan′s experience in the differentiation and treatment of motor neuron disease, which can be categorized into flaccidity syndrome, convulsive syndrome, and fei syndrome according to the clinical manifestations. These three syndromes may coexist, and the condition progressively worsens over time, which is believed to be caused by external pathogenic qi, based on "deficient-qi induced stagnation" , and with "toxins damaging collaterals" as the core etiology and pathogenesis. "Toxins damaging collaterals" involves three levels of qi collaterals, blood collaterals, and fluid collaterals, gradually overlapping and affecting the marrow collaterals. Academician WANG Yongyan′s theory is based on syndrome differentiation, breaking down the boundaries of flaccidity, convulsive, and fei syndromes according to different manifestations of the disease, and using the concept of "combined treatment" for treatment. The clinical presentation of motor neuron disease shows a bottom-up trend in the development of the sanjiao, and the combination of visceral syndrome differentiation and sanjiao syndrome differentiation can grasp the progress of the disease comprehensively. During the process of syndrome differentiation, the focus is on the use of xiang thinking, emphasizing the holistic correlation between diseases and syndromes and the integrated effect of reductionist analysis. Treatment is based on xiang differentiation and individualized treatment. The mid-stage of motor neuron disease is the key time point for the treatment of this disease. Based on the clinical symptoms of flaccidity, convulsive, and fei syndromes, where treatment should focus on reinforcing the spleen and kidney, combining moxibustion with herbal medicine. While targeting the disease, treatment should comprehensively apply the methods of "promoting, supplementing, softening, and warming" to eliminate toxins and unblock collaterals, and restore the neural regulation of the brain and spinal cord.

The "body schema" of acupuncture and moxibustion is centered on the meridian system and represents a corporeal perspective of "heaven-connection", embodying the harmony between nature and humanity. It integrates the cyclic schema of the heavenly cycling, the meridian growth and decline schema of the guaqi theory, the twelve zodiac demarcation schema from astrological and astronomical studies, and the nine-palace and eight-trigrams schema of temporal and spatial locations. It presents the theoretical origins of the harmony between nature and humanity in acupuncture and moxibustion along with medical thoughts under the background of social concepts. The numerical arts of acupoint number and acupuncture-moxibustion quantity, those of acupuncture-moxibustion time and taboos, as well as the time-based acupuncture-moxibustion patterns, all of these thoroughly reflect the application of the body schema of acupuncture and moxibustion by early medical practitioners in ancient time. The study on the body philosophy in acupuncture and moxibustion should start from the original appearance of early classical acupuncture-moxibustion theory, trace the source of body philosophy of acupuncture and moxibustion, seek the truth of temporal body medicine, and perfect the body philosophy research of contemporary acupuncture and moxibustion, so as to improve the dual attributes of acupuncture and moxibustion in humanities and science.

Alzheimer's disease (AD) is the major form of dementia in the elderly and is closely related to the toxic effects of microglia sustained activation. In AD, sustained microglial activation triggers impaired synaptic pruning, neuroinflammation, neurotoxicity, and cognitive deficits. Accumulating evidence has demonstrated that aberrant expression of deubiquitinating enzymes is associated with regulating microglia function. Here, we use RNA sequencing to identify a deubiquitinase YOD1 as a regulator of microglial function and AD pathology. Further study showed that YOD1 knockout significantly improved the migration, phagocytosis, and inflammatory response of microglia, thereby improving the cognitive impairment of AD model mice. Through LC-MS/MS analysis combined with Co-IP, we found that Myosin heavy chain 9 (MYH9), a key regulator maintaining microglia homeostasis, is an interacting protein of YOD1. Mechanistically, YOD1 binds to MYH9 and maintains its stability by removing the K48 ubiquitin chain from MYH9, thereby mediating the microglia polarization signaling pathway to mediate microglia homeostasis. Taken together, our study reveals a specific role of microglial YOD1 in mediating microglia homeostasis and AD pathology, which provides a potential strategy for targeting microglia to treat AD.

This article explores the practical situation,construction significance,core points,and enhancement dimensions in constructing the discourse system of traditional Chinese medicine from a macro perspective.It also examines the ways linguistics can help alleviate the challenges in this process.The discourse system of traditional Chinese medicine has gone through three stages.The theory is currently unclear,and the discourse cannot be transmitted without fundamentally solving the problem of"aphasia."The discourse system of traditional Chinese medicine is an inevitable requirement for creating modern and international traditional Chinese medicine models.Its construction must form a subjective understanding of the discourse system,strengthen the advantage of originality,establish an expression paradigm of original system interpretation and new expressions of modern novel quality development,and build an influential international discourse system.The improvement dimension of the discourse system of traditional Chinese medicine should focus on domestic popularization and global dissemination.Strong strategic support should be provided using the epistemological and methodological frameworks of both traditional and modern linguistics.

Background With urbanization and residential space expansion, ecological environment and human health issues have become hot social topics. Forest health, as a way of seeking health in nature, has begun to receive public attention in the context of the gradually increasing sub-healthy population and various psychological and physical diseases at a young age. Objective To systematically evaluate the effects of forest therapy on selected physical and mental health indicators. Methods Relevant research literature was retrieved from domestic and international databases (China National Knowledge Infrastructure, Wanfang Database, China Biomedical Literature Service System, Web of Science, ScienceDirect, PubMed, Embase, and Cochrane Library), with a time range from database establishment to January 31, 2023. Relevant data were extracted for meta-analysis to explore the relationship between forest therapy and selected psychological and physiological indicators. Results A total of 85 articles were included, and the meta-analysis results showed that better scores of Profile of Mood States, Positive and Negative Affect Scale, Beck Depression Inventory, and State Trait Anxiety Scale were found in the forest group than those in the urban group (P<0.05); the levels of systolic blood pressure, diastolic blood pressure, heart rate, sympathetic nerve indicator [ln (LF/HF)], salivary cortisol, and serum inflammatory factors were lower in the forest group than in the urban group, while parasympathetic nerve indicator [ln (HF)] level was higher in the forest group than in the urban group (P<0.05). The results of subgroup analysis showed that the changes in heart rate (SMD=−1.62, 95%CI: −2.41, −0.82), ln (HF) (SMD=1.29, 95%CI: 0.73, 1.85), ln (LF/HF) (SMD=−1.49, 95%CI: −2.13, −0.86), and salivary cortisol (SMD=−0.53, 95%CI: −0.81, −0.25) were more significant when the duration of forest therapy was ≤ 0.5 h, the recovery effect on emotional state was better in the >0.5~3 h group (such as tension SMD=−2.40, 95%CI: −3.21, 1.59), and the reduction effects on systolic blood pressure (SMD=−0.53, 95%CI: −1.03, −0.03) and diastolic blood pressure (SMD=−0.42, 95%CI: −0.88, 0.04) were better in the >3 h group. Seated meditation showed better recovery effects on multiple indicators of Profile of Mood States (such as fatigue SMD=−2.26, 95%CI: −3.07, −1.45), while walking showed better recovery effects on physiological indicators such as blood pressure (systolic blood pressure SMD=−0.57, 95%CI: −1.07, −0.06; diastolic blood pressure SMD=−0.72, 95%CI: −1.36, −0.07) and heart rate (SMD=−1.51, 95%CI: −2.38, -0.64). Except for blood pressure, the health benefits of forest therapy in the younger age group were generally better than those in the middle-aged and elderly group. Conclusion Relaxed and comfortable psychological feeling is reported when practicing forest therapy; it can lower blood pressure and heart rate, regulate the autonomic nervous system; it can also reduce the release of stress hormones and lower serum levels of inflammatory factors, exerting an auxiliary recovery effect on cardiovascular and immune system disorders. At the same time, the therapy duration, form, and age of the subjects have a certain impact on the effects of forest therapy practice.

The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.

As an important part of tumor microenvironment, neutrophils are poorly understood due to their spatiotemporal heterogeneity in tumorigenesis. Here we defined, at single-cell resolution, CD44-CXCR2- neutrophils as tumor-specific neutrophils (tsNeus) in both mouse and human gastric cancer (GC). We uncovered a Hippo regulon in neutrophils with unique YAP signature genes (e.g., ICAM1, CD14, EGR1) distinct from those identified in epithelial and/or cancer cells. Importantly, knockout of YAP/TAZ in neutrophils impaired their differentiation into CD54+ tsNeus and reduced their antitumor activity, leading to accelerated GC progression. Moreover, the relative amounts of CD54+ tsNeus were found to be negatively associated with GC progression and positively associated with patient survival. Interestingly, GC patients receiving neoadjuvant chemotherapy had increased numbers of CD54+ tsNeus. Furthermore, pharmacologically enhancing YAP activity selectively activated neutrophils to suppress refractory GC, with no significant inflammation-related side effects. Thus, our work characterized tumor-specific neutrophils in GC and revealed an essential role of YAP/TAZ-CD54 axis in tsNeus, opening a new possibility to develop neutrophil-based antitumor therapeutics.

OBJECTIVE To analyze existing problems of pharmacoeconomic evaluation research in China and to improve the standardization and scientificity of research, so as to provide more high-quality evidence for government decision-making. METHODS Retrieved from CNKI, Wanfang database, VIP, PubMed, Web of Science from 2018 to 2022, the literature related to pharmacoeconomic evaluation in China was collected; Excel 2016 software was used to extract the key information of the included literature which met inclusion criteria. The Quality of Health Economic Studies (QHES) scale was used to evaluate the quality of the included literature. RESULTS A total of 113 pieces of literature were included in this study, involving 85 pieces of Chinese literature and 28 pieces of English literature. The overall score of QHES included literature was 65.7, of which the average score of Chinese literature was 62.0 and English literature was 76.9. The median quality scores for the literature in 2018, 2019, 2020, 2021 and 2022 were 62.0, 70.5, 59.3, 71.0, and 73.0, respectively. Of these, 65 pieces of literature reported the research perspective; 36 reported the discount rate indistinctly; 25 provided unclear definitions of thresholds; and 53 used two sensitivity analysis methods. Among different items of the QHES scale, item 2 (research perspective), item 8 (time range and discount rate), item 14 (potential bias) and item 16 (sources of funding) had low percentage of scores. CONCLUSIONS From 2018 to 2022, pharmacoeconomic evaluation literature published by Chinese academics has generally shown a fluctuating upward trend in terms of quality, but there is still some room for improvement. The main problems in current pharmacoeconomics research in China include unclear understanding of the research perspective, single measurement of cost and health outcomes, unreasonable design of time horizon, indistinct description of the threshold or discount rate, and lack of sensitivity analysis.

Objective:To investigate the timing of rivaroxaban re-administration after upper gastrointestinal bleeding in patients with lower extremity deep venous thrombosis.Methods:The clinical data of 176 patients who suffered from lower limb deep vein thrombosis due to trauma or surgery and upper gastrointestinal bleeding due to oral rivaroxaban and received treatment in the Third Hospital of Hebei Medical University from May 2018 to October 2021 were retrospectively analyzed. These patients were divided into an early group (≤ 7 days) ( n = 84 cases) and a late group (> 7 days) ( n = 92 cases) according to the timing of rivaroxaban re-administration. All patients were followed up for 2 months to record hemoglobin, D-dimer, and platelet values. The progression of deep venous thrombosis of the lower extremities was observed. The rebleeding rate, progression of lower extremity deep venous thrombosis, and mortality were analyzed. Results:There were no significant differences in hemoglobin and D-dimer levels between the two groups on admission (both P > 0.05). After admission, the D-dimer level in the late group was (4.1 ± 2.3) mg/L, which was significantly higher than (3.1 ± 1.9) mg/L in the early group ( t = 3.17, P < 0.05). After admission, hemoglobin level in each group was significantly decreased compared with that on admission (both P < 0.05). The lowest hemoglobin level in the late group was (78.7 ± 8.3) g/L, which was significantly higher than (75.6 ± 8.2) g/L in the early group ( t = 2.32, P < 0.05). There was no significant difference in rebleeding rate between early and late groups [5.95% (5/84) vs. 1.08% (1/92)] (log-rank 3.07, P > 0.05). Lower extremity deep venous thrombosis progressed more slowly in the early group compared with the late group [2.38% (2/84) vs. 10.86% (10/92)] (log-rank = 4.61, P < 0.05). Conclusion:Rivaroxaban should be re-administered as soon as possible after upper gastrointestinal bleeding in patients with lower extremity deep venous thrombosis.
