Malignant tumors are one of the major diseases that endanger human life and health. Chinese medicine has unique advantages in clinical anti-tumor treatment. However, how to translate the anti-tumor effects of Chinese medicine into clinical practice is the core issue that must be addressed in the process of treating malignant tumors with traditional Chinese medicine (TCM). Unlike modern chemical drugs, the compatibility application of Chinese medicine is the key factor that determines whether Chinese medicine can achieve optimal anti-tumor efficacy and realize the goal of "enhancing efficacy and reducing toxicity". The formulation structure based on this compatibility is the basic form for the safe, efficient, and rational clinical use of anti-tumor Chinese medicine, and it mainly includes three categories: herb pairs, tri-herbal combinations, and compound compatibility. Although herb pairs have the characteristics of a simple structure and strong targeting (enhancing efficacy and reducing toxicity), they often have a single effect and cannot fully address the complex pathogenesis of tumors. As a result, herb pairs are rarely used alone in practice. Compared to herb pairs, tri-herbal combinations broaden the application scope of herbs in clinical treatment, but their therapeutic range remains limited. The traditional "sovereign, minister, assistant, and guide" compound prescription, which includes herb pairs and tri-herbal combinations, improves the efficacy of herbs in treating serious diseases, hypochondriasis, chronic diseases, and miscellaneous disorders. However, due to the limitations of its historical background, it has not been integrated with modern clinical practice and modern pharmacological research, which restricts the development of compound compatibility theory. With the emergence of modern medical technology, it has been combined with traditional compatibility theory of Chinese medicine to create an innovative modern compatibility theory. This includes the "aid medicine" theory derived from modern Chinese medicine pharmacology, which compensates for the inability of the "sovereign, minister, assistant, and guide" theory to accurately apply medicine. Additionally, the "state-targeted treatment based on syndrome differentiation" theory, developed from pharmacology and modern medicine, addresses the deficiency in disease cognition in the "sovereign, minister, assistant, and guide" theory. Under the guidance of these compatibility forms and theories, clinical anti-tumor Chinese medicine can exert its maximum anti-tumor efficacy, which is of great significance for the application of Chinese medicine in clinical tumor treatment.

Objective·To develope an auditory brainstem implant(ABI)vocoder based on cochlear implant(CI)vocoder characteristics and ABI electrode array topology,and to verify its reliability.Methods·An"n-of-m"coding strategy CI/ABI vocoder was constructed based on MATLAB.Within each frame,only the envelopes of the n channels with the highest energy were selected.The interaction coefficient(IC)(range:1?3),channel numbers(range:5?22),and electrode array topology(CI/ABI)were adjustable parameters,allowing for the synthesis of simulated speech.Psychoacoustic evaluation was employed,recruiting normal hearing subjects to perform closed-set simulated phoneme perception.The phoneme recognition accuracy(20 vowel questions/condition,11 consonant questions/condition)was compared with the corresponding conditions of CI and ABI from reference literature to determine the IC value of the vocoder and verify its reliability.Results·The vocoder successfully synthesized all test stimuli.In the closed-set CI-simulated speech recognition,the simulated vowel and consonant recognition accuracy for IC2 and IC3 conditions showed no significant difference compared to the accuracy reported in the CI reference literature(P>0.05).The difference in vowel and consonant accuracy between IC2 and the literature was smaller than that between IC3 and the literature(vowel|d|=1.6%vs.20%,consonant|d|=8.4%vs.9.9%),thus determining the optimal interaction coefficient of this model as 2.Subsequently,when modifying the electrode array topology to ABI,it was found that the simulated phoneme recognition accuracy for a 16-channel ABI was significantly lower than that for the 16-channel CI group,consistent with the reported literature.The simulated vowel and consonant accuracy within the 5?8 channel range for ABI showed no significant difference(P>0.05),also aligning with the trend reported in the literature.Conclusion·A CI/ABI vocoder based on"n-of-m"coding strategy is established and the optimal IC is determined.The established ABI encoder has been evaluated for high reliability through psychoacoustic experiments.It provides suitable technical means for validating ABI-specific coding strategies.
3.A consensus on the management of allergy in kindergartens and primary schools
Chinese Journal of School Health 2023;44(2):167-172
Abstract
Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Background:
The treatment of trigeminal neuralgia remains a challenging issue.Stem cells from human exfoliated deciduous teeth (SHED) provide optimized therapy for chronic pain. This study aimed to investigate the mechanisms underlying the attenuation of trigeminal neuralgia by SHED.
Methods:
Trigeminal neuralgia was induced by chronic constriction injury of the infraorbital nerve. The mechanical threshold was assessed after model establishment and local SHED transplantation. Endoplasmic reticulum (ER) morphology and Caspase12 expression in trigeminal ganglion (TG) was evaluated as well. BiP expression was observed in PC12 cells induced by tunicamycin.
Results:
The local transplantation of SHED could relieve trigeminal neuralgia in rats.Further, transmission electron microscopy revealed swelling of the ER in rats with trigeminal neuralgia. Moreover, SHED inhibited the tunicamycin-induced up-regulated expression of BiP mRNA and protein in vitro. Additionally, SHED decreased the up-regulated expression of Caspase12 mRNA and protein in the TG of rats caused by trigeminal neuralgia after chronic constriction injury of the infraorbital nerve mode.
Conclusions
This findings demonstrated that SHED could alleviate pain by relieving ER stress which provide potential basic evidence for clinical pain treatment.

The radial artery pulse wave contains a wealth of physiological and pathological information about the human body, and non-invasive studies of the radial artery pulse wave can assess arterial vascular elasticity in different age groups.The piezoelectric pulse wave transducers were used to non-invasively acquire radial artery pulse waves at different contact pressures in young and middle-aged and elderly populations. The radial artery waveforms were decomposed using a triangular blood flow model fitting method to obtain forward and reflected waves and calculate reflection parameters. Finally a correlation analysis and regression analysis of the contact pressure Psensor with the reflection parameters was carried out. The results showed that the reflection parameters RM, RI and Rd had a strong negative correlation with Psensor in both types of subjects, and the correlation coefficients and slopes of the regression curves were significantly different between the two types of subjects (P<0.05). Based on the results of this study, excessive contact pressure on the transducer should be avoided when detecting radial artery reflection waves in clinical practice. The results also show that the magnitude of the slope of the regression curve between the reflection parameters and the transducer contact pressure may be a potentially useful indicator for quantifying the elastic properties of the vessel.

Objective:To analyze the clinical effect of extracorporeal membrane oxygenation (ECMO) in the treatment of burn patients with acute respiratory distress syndrome (ARDS).Methods:The retrospective observational study and the systematic review were applied. From March 2014 to July 2020, five burn patients with ARDS received ECMO treatment in the First Affiliated Hospital of Army Medical University (the Third Military Medical University). All the five patients were male, aged from 40 to 62 years. The average total burn surface area was 58.8% total body surface area (TBSA) and four cases had severe inhalation injury. Patient's ECMO starting time, duration and mode, and whether successfully weaned or the cause of death, and others. were recorded. Furthermore, the changes of oxygenation and infection before, during, and after utilizing ECMO were analyzed. PubMed and Web of Science from the establishment of each database to August 2021 were searched using "Extracorporeal Membrane Oxygenation", "ECMO", "burn", "inhalation" as the search terms and "Title/Abstract" as the field to retrieve the clinical articles that meet the selection criteria . Basic information were extracted from the articles, including sample size, gender, age, total burn area, inhalation injury, the indication of ECMO, the start and lasting time of ECMO, ECMO mode, rate of successful weaning, complications of ECMO, mortality, the combined application of continuous renal replacement therapy (CRRT). Results:Five patients started venovenous ECMO on an average of 10.2 days after injury and lasted an average of 180.4 hours. Three out of 5 patients were weaned successfully with one patient survived. Four patients died of multiple organ dysfunction syndrome (MODS) and septic shock. Compared with those before ECMO treatment, the arterial oxygen partial pressure (PaO 2) and oxygen saturation in arterial blood (SaO 2) of three successfully weaned patients obviously increased during and after ECMO treatment. The fraction of inspired oxygen (FiO 2) decreased below 50% and PaO 2/FiO 2 ratio increased above 200 mmHg (1 mmHg=0.133 kPa) during and after ECMO. Furthermore, lactic acid and respiratory rate decreased, basically. Compared with those before ECMO, PaO 2 and SaO 2 in the other two patients during ECMO, who failed to be weaned, continuously decreased while lactic acid increased. Before and during ECMO, the PaO 2/FiO 2 ratios of unsuccessfullg weaned cases were less than 200 mmHg, and partial pressure of carbon dioxide in arterial blood (PaCO 2) were more than 40 mmHg. Compared with those before ECMO, there were no significant changes in body temperature during and after ECMO, which were less than 38 ℃. Compared with those before ECMO, the leucocyte number (the index without this in unsuccessfully weaned cases was omitted, the same as below) in four patients showed a significant decrease during ECMO, but rose after removal of ECMO. The proportion of neutrophils in three patients were slightly higher during ECMO than before ECMO, and did not change significantly after removal of ECMO. Compared with those before ECMO, platelet counts in three patients were significantly reduced during ECMO, and all five patients during ECMO were below normal levels. Compared with those before ECMO, the procalcitonin levels in four deaths were significantly increased during ECMO. Catheter culture of microorganism was performed in three successfully weaned patients, all of which were negative. A total of 13 literature were included, ranging from 1990 to 2019. The sample size in 6 studies was less than 10, and the sample size in 4 studies was between 10 and 20, and only 2 literatures had a sample size larger than 50. ECMO was applied in 295 burn patients with overall mortality of 48.8% (144/295), including 157 adults and 138 children. The most common indication of ECMO was severe ARDS. Among 157 adult burn patients (95 males and 65 females), 36 cases had inhalation injury. The average burn area was 27%-37%TBSA in 5 reported studies and was more than 50%TBSA in 2 reported studies. The most common mode was venovenous ECMO. ECMO treatment began 26.5 hours to 7.4 days after injury and lasted from 90 hours to 18 days, and the rate of successful weaning ranged from 50% to 100%. The most common complications were bleeding and infection. The mortality was 52.9% (83/157). MODS and sepsis were the leading causes of death. Among 138 pediatric burn patients (77 boys and 61 girls), 29 patients had inhalation injury. The average burn area was 17%-50.2%TBSA in 3 studies. ECMO treatment lasted from 165.2 hours to 324.4 hours. Bleeding was the most common complication. The mortality was 44.2% (61/138). Conclusions:ECMO is an effective strategy for the salvage treatment of burns complicated with ARDS. Furthermore, the prevention and treatment of bleeding, infection and organ dysfunction should be emphasized during the use of ECMO. More importantly, evidence-based guidelines for burns are urgently needed to further improve the clinical effect of ECMO.

Objective:To investigate the cognitive status of fatigue among patients with coronary heart disease (CHD) in the community and analyze its influencing factors.Methods:From May to July 2020, a total of 250 patients with CHD in the community were selected as the research objects by multi-stage sampling method. The general information questionnaire and Fatigue Cognition Questionnaire for Patients with CHD were used for investigation. Multiple linear regression analysis was used to analyze the influencing factors. A total of 250 questionnaires were distributed and 245 were effectively recovered.Results:The total score of fatigue cognition of 245 patients with CHD in the community was 6 (4, 7) . Univariate analysis showed that there were statistically significant differences in the total scores of fatigue cognition among community CHD patients with different education level, duration of disease, grading of cardiac function, whether pay attention to fatigue knowledge, number of combined chronic diseases and treatment methods ( P<0.05) . Multiple linear regression analysis showed that education level, duration of disease, whether pay attention to fatigue knowledge, number of combined chronic diseases and treatment methods were the main influencing factors on fatigue cognition of CHD patients in the community ( P<0.05) . Conclusions:The cognition of patients with CHD in the community on fatigue needs to be improved, and community medical workers should take corresponding measures to increase the attention and active response of patients with CHD to fatigue.

Objective:To evaluate the clinical application of the SITA faster (SFR) visual field strategy in glaucoma patients.Methods:A diagnostic test was adopted.A total of 72 subjects who visited the Eye and ENT Hospital Affiliated to Fudan University during September 2018 to February 2019 were collected, including 28 normal subjects (56 eyes) and 44 glaucoma patients (86 eyes). The consistency and convenience of visual field tests were evaluated using SITA Standard (SS) and SITA Fast (SF), or SS and SITA Faster (SFR) in normal subjects and glaucoma patients.Test duration, visual field index (VFI), mean deviation (MD) and the number of defect points with probabilities of <5%, <2%, <1%, and <0.5% in the pattern deviation probability plots were recorded, and tested for difference, correlation and consistency.This study followed the Declaration of Helsinki.Written informed consent was obtained from all subjects prior to their entering the study cohort.The study protocol was approved by the Ethics Committee of the Eye and ENT Hospital of Fudan University.Results:For all of the included subjects, the mean test durations of SF and SFR were (64±13)% and (44±10)% compared to that of SS, respectively.MD and VFI evaluated by SS and SF, or by SS and SFR, showed no significant difference in either the normal subjects or the glaucoma patients (all at P>0.05). Across all included subjects, the positive correlation and consistency of MD and VFI were good ( r=0.99, P<0.01). However, for the results of the probability points in the pattern deviation probability blot, there was no difference among normal subjects, but the correlation and consistency were not good.In the deviation probability blot, there was a greater number of defect points of P<0.5% in glaucoma patients evaluated via SS compared to those evaluated by SFR, and the difference was statistically significant ( Z=-2.28, P=0.02). Apart from this, the number of defect points in glaucoma patients showed no difference between SS and SF, or between SS and SFR, and the correlation and consistency were higher in glaucoma patients than those in the normal subjects. Conclusions:Compared with SF and SS, SFR saves more test time.Except for partial variances in the pattern deviation probability blot, the difference between visual field strategies is relatively small and the results are basically consistent.

To explore the role of dentritic epidermal T lymphocytes ( DETCs) in immune rejection of skin allograft in mice and its related mechanism. Methods (1) Full-thickness skin was harvested from back of one male wild type (WT) C57BL/6 mouse. Epithelial cells were isolated for detection of the expression of DETCs and their phenotype with flow cytometer. Another male WT C57BL/6 mouse was used to harvest full-thickness skin from the back. Epidermis was isolated for observation of the morphological characteristics of DETCs with immunofluorescence technology. (2) Four male green fluorescence protein (GFP)-marked C57BL/6 mice, 7 female WT C57BL/6 mice (group WT), and 7 female ybT lymphocytes 8 gene knock-out (GK) C57BL/6 mice (group GK) were used. Full-thickness skin in the size of 1.4 cm x 1.4 cm on the back of mice in groups WT and GK were excised, and the wounds were transplanted with full-thickness skin in the size of 1.2 cm x 1.2 cm obtained from male GFP-marked C57BL/6 mice. The survival time of skin grafts was affirmed with small animal in vivo imager and naked eyes and recorded. (3) Two male WT C57BL/6 mice were used to isolate epithelial cells. Cells were inoculated into 48-well plate and divided into activation group (A) and control group (C) according to the random number table, with 4 wells in each group. Cells in group A were treated with 10 pL concanavalin A in the concentration of 2 microg/mL for 24 hours, while those in group C with PBS in the same volume as that in group A. The expression of interferon y in DETCs was detected with flow cytometer. (4) Four male GFP-marked C57BL/6 mice were used as donors. Fourteen female WT C57BL/6 mice were used as receptors and divided into interferon gamma neutralizing group (IN) and control group (C) according to the random number table, with 7 mice in each group. The skin transplantation model of C57BL/6 male to C57BL/6 female was established as in part (2). Before surgery and 72 hours after, mice in group IN were intraperitoneally injected with 200 pL interferon y neutralizing antibody in the concentration of 1 mg/mL, and those in group C with normal saline in the same volume as that in group IN. The survival time of skin grafts was observed and recorded using the methods in part (2), and the result of group IN was compared with that of group GK in part (2). The survival curve of skin grafts was processed with Log-rank ( Mantel-Cox) test. Results (1) The positive expression rate of DETCs in epithelial cells of skin in mouse was 7.27%, and they were all CD3 cells. DETCs were found to be scattered in the epidermis of skin in mouse with dendritic morphology. (2) The survival time of skin grafts of mice in group GK was 22-35 d, obviously longer than that in group WT (12-16 d, y2 = 14. 10 , P < 0.001). (3) Expression of interferon gamma was detected in 22. 70% DETCs in group A, which was obviously higher than that in group C (0.51%). (4) The survival time of skin grafts of mice in group IN was 19-24 d, which was obviously longer than that in group C (12-16 d, chi 2 = 13.60, P < 0.001) but close to that in group GK as in part (2) (chi2 = 0.06, P = 0.810). Conclusions DETCs are involved in promotion of immune rejection of skin allograft probably by secretinf interferon gamma.
