ABSTRACT
Objective To investigate the environmental contamination related to first patient with carbapenem-re-sistant Acinetobacter baumannii(CRAB)infection and the infection status of relevant patients in a newly established intensive care unit(ICU)of a hospital in Tibetan area,and analyze the transmission risk.Methods From the ad-mission in ICU of a patients who was first detected CRAB on November 15,2021 to the 60th day of hospitalization,all patients who stayed in ICU for>48 hours were performed active screening on CRAB.On the 30th day and 60th day of the admission to the ICU of the first CRAB-infected patient,environment specimens were taken respectively 2 hours after high-frequency diagnostic and therapeutic activities but before disinfection,and after disinfection but before medical activities.CRAB was cultured with chromogenic culture medium.Results Among the 13 patients who were actively screened,1 case was CRAB positive,he was transferred from the ICU of a tertiary hospital to the ICU of this hospital on November 19th.On the 40th day of admission to the ICU,he had fever,increased frequency for sputum suction,and CRAB was detected.The drug sensitivity spectrum was similar to that of the first case,and he also stayed in the adjacent bed of the first case.64 environmental specimens were taken,and 9 were positive for CRAB,with a positive rate of 14.06%,8 sampling points such as the washbasin,door handle and bed rail were positive for CRAB after high-frequency diagnostic and therapeutic activities.After routine disinfection,CRAB was detected from the sink of the washbasin.Conclusion For the prevention and control of CRAB in the basic-level ICU in ethnic areas,it is feasible to conduct risk assessment on admitted patients and adopt bundled prevention and con-trol measures for high-risk patients upon admission.Attention should be paid to the contaminated areas(such as washbasin,door handle,and bed rail)as well as the effectiveness of disinfection of sink of washbasin.
ABSTRACT
Objective: To assess the efficacy and cost-effectiveness of high-dose dual therapy compared with bismuth-containing quadruple therapy for treating Helicobacter pylori(H.pylori) infection in servicemen patients. Methods: A total of 160 H. pylori-infected, treatment-naive servicemen, including 74 men and 86 women, aged from 20 years to 74 years, with a mean (SD) age of 43 (13) years, tested in the First Center of Chinese PLA General Hospital from March 2022 to May 2022 were enrolled in this open-label, randomized controlled clinical trial. Patients were randomly allocated into 2 groups: the 14-day high-dose dual therapy group and the bismuth-containing quadruple therapy group. Eradication rates, adverse events, patient compliance, and drug costs were compared between the two groups. The t-test was used for continuous variables, and the Chi-square test for categorical variables. Results: No significant difference in H. pylori eradication rates were found between high-dose dual therapy and bismuth-containing quadruple therapy by ITT, mITT and PP analysis[ITT:90.0% (95%CI 81.2%-95.6%) vs. 87.5% (95%CI 78.2%-93.8%), χ2=0.25, P=0.617;mITT:93.5% (95%CI 85.5%-97.9%) vs. 93.3% (95%CI 85.1%-97.8%), χ2<0.01, P=1.000; PP: 93.5% (95%CI 85.5%-97.9%) vs. 94.5% (95%CI 86.6%-98.5%), χ2<0.01, P=1.000 ]. The dual therapy group exhibited significantly less overall side effects compared with the quadruple therapy group [21.8% (17/78) vs. 38.5% (30/78), χ2=5.15,P=0.023]. There were no significant differences in the compliance rates between the two groups [98.7%(77/78) vs. 94.9%(74/78), χ2=0.83,P=0.363]. The cost of medications in the dual therapy was 32.0% lower compared with that in the quadruple therapy (472.10 RMB vs. 693.94 RMB). Conclusions: The dual regimen has a favorable effect on the eradication of H. pylori infection in servicemen patients. Based on the ITT analysis, the eradication rate of the dual regimen is grade B (90%, good). Additionally, it exhibited a lower incidence of adverse events, better compliance and significantly reduced cost. The dual regimen is expected to be a new choice for the first-line treatment of H. pylori infection in servicemen but needs further evaluation.

Objective:To explore different strategies of central repair first or malperfusion first to treat type A aortic dissection complicated with limb malperfusion.Methods:From January 2020 to December 2021, 302 patients were diagnosed with acute type A aortic dissection, and 17 consecutive patients were diagnosed as type A acute aortic dissection complicated with limb malperfusion and underwent Sun’s procedure. There were 16 males and 1 female with an average of(52.6±4.2)years. Surgical strategies were as follows: immediate central repair-Sun’s procedure in 14 patients, endovascular stenting followed by central repair in 3 patients, endovascular stenting after central repair in 1 patient.Results:The incidence rate of limb malperfusion of acute Stanford A aortic dissection was 5.6%(17/302). Average extracorporeal circulation time was(271.8±38.9)min, average aortic cross-clamp time was (186.3±31.8)min, and the average circulatory arrest time was (48.75±11.3)min. Early mortality rate was 17.6%(3/17). Two patients were left hospital voluntarily because of cerebral infarction. One patient underwent leg incision osteofascial compartment syndrome and discharged unevently. Five patients underwent continuous renal replacement therapy and hemoperfusion. Follow-up results showed that patients with serious limb malperfusion have symptoms of nerve dysfunction including amyosthenia and sensory disturbance, but recovered gradually with rehabilitation.Conclusion:Sun’s procedure is safe and feasible for type A acute aortic dissection complicated with mild limb malperfusion. For serious limb malperfusion, endovascular stent followed by Sun’s procedure is a good choice with CRRT and hemoperfusion.
ABSTRACT
Glaucomatous optic neuropathy(GON)is the difficulty of glaucoma treatment. In recent years, a variety of theories have been put forward about the pathogenesis of GON, but none of them can explain the principle of optic neuropathy caused by all types of glaucoma, which makes the disease difficult to treat in clinical treatment and is not conducive to early intervention. The latest research found that the transient receptor potential channel vanillic acid subfamily 4(TRPV4)in the retina plays an important role in various pathogenesis of GON. This article will review TRPV4 and its role in the occurrence and development of GON in order to find a common “connection point” for the multiple mechanism theories of GON, which will contribute to further understanding and clinical treatment of the disease.
ABSTRACT
AIM: To systematically evaluate the efficacy of intense pulsed light(IPL)combined with meibomian gland expression(MGX)in the treatment of meibomian gland dysfunction(MGD)-related dry eye disease(DED).METHODS: Chinese and English databases such as Chinese national knowledge infrastructure(CNKI), Wanfang, VIP, CBM, ClinicalTrials, PubMed, Embase and Web of Science were searched, and clinical randomized controlled trials(RCTs)using IPL combined with MGX in the experimental group and MGX alone in the control group from January 2017 to September 2022 were included. Six outcome indicators including clinical efficacy, ocular surface disease index(OSDI)score, break-up time(BUT), corneal fluorescein staining(CFS)score, tear meniscus height(TMH)and meibomian gland yielding secretion score(MGYSS)were Meta analyzed by Review Manager 5.3 and Stata 14 software.RESULTS: A total of 15 RCTs were included, with 1 345 patients with MGD-related dry eye. Meta-analysis results showed that the treatment of MGD-related dry eye in the experimental group improved better clinical efficacy(OR=4.95, 95%CI: 2.76~8.90, Z=5.35, P&#x003C;0.00001), BUT(SMD=1.26, 95%CI: 0.84~1.69, Z=5.78, P&#x003C;0.00001), TMH(SMD=0.37, 95%CI: 0.15~0.59, Z=3.33, P=0.0009), and reduced OSDI scores(SMD=-0.86, 95%CI: -1.44~-0.27, Z=2.85, P=0.004)as well as MGYSS(SMD=-2.43, 95%CI: -4.31~-0.54, Z=2.52, P=0.01)than the control group. However, there was no statistically significant difference in CFS scores(SMD=-0.19, 95%CI: -0.46~0.07, Z=1.43, P=0.15).CONCLUSION: IPL combined with MGX in the treatment of MGD related dry eye can increase the overall effective rate and improve the symptoms and signs of patients with MGD related dry eye better than MGX alone.
ABSTRACT
ObjectiveTo investigate the quality variation of Lonicera japonica flower from different harvesting periods by ultraviolet visible(UV-Vis) fingerprint combined with chemometrics. MethodTwenty-five L. japonica flower samples from five harvesting periods, including young bud stage,green bud stage,white bud stage,silver and golden flower stages, were collected, with five samples for each stage. UV-Vis fingerprints of L. japonica flower from different harvesting periods were established in the context of the optimum extraction method based on the single factor experiment. The results showed that the absorption values at 209,216,226,250,280,303,318, and 350 nm were significantly different. Moreover,after data pretreatment and normalization,multivariate statistical analyses, such as principal component analysis (PCA),partial least squares discriminant analysis (PLS-DA),and orthogonal PLS-DA (OPLS-DA)were performed by SIMCA-P+ to establish the quality variation model of L. japonicas flower from harvesting periods. ResultAs revealed by PCA and PLS-DA, L. japonicas flower samples from five harvesting periods were clustered separately and closely in a harvesting time-dependent manner, suggesting that the content of components contained in samples from different harvesting periods was highly distinct and correlated with harvesting periods. The pairwise comparison of OPLS-DA indicated that triterpenoids or volatile oils were the main components causing the changes from the young bud stage to the green bud stage,and the content of them decreased. The main components from the green bud stage to the white bud stage were triterpenoids (or iridoids),volatile oils,phenolic acids, or flavonoids,and the content of them decreased, which was consistent with the HPLC result of chlorogenic acid. From the white bud stage to the silver flower stage, the main components were iridoids (increasing in content) and triterpenoids (or volatile oils) (decreasing in content). The main altered components from the silver flower stage to the golden flower stage were triterpenoids (or volatile oils) whose content increased. ConclusionThis method is simple and feasible, which can provide references for the quality control of Chinese medicine.
ABSTRACT
In recent years, foreign countries are gradually implementing broad consent to improve the utilization of medical data and biological samples, but broad consent may face ethical issues such as imperfect notification and affecting the rights of subjects. There are already relevant regulations and practices on broad consent in foreign countries. The concept of broad consent is not clearly defined in China′s laws. At present, the treatment of biological samples can be roughly divided into four categories in practice, and there is potential application space for broad consent. The specific scope of broad consent should be clarified, distinguished from donation behavior, and the implementation of broad consent should be explored on the basis of protecting the rights of subjects.

Acute lung injury is one of the common complications in the perioperative period of acute aortic dissection, which has serious effects on the prognosis of patients with acute aortic dissection and increase the mortality. Therefore, the prevention and treatment of acute lung injury complicated by acute aortic dissection is an urgent problem in clinic. This paper reviewed the risk factors, pathogenesis, methods for preservation and treatment for acute lung injury complicated by acute aortic dissection.
ABSTRACT
BACKGROUND@#Patients' recovery after surgery is the major concern for all perioperative clinicians. This study aims to minimize the side effects of peri-operative surgical stress and accelerate patients' recovery of gastrointestinal (GI) function and quality of life after colorectal surgeries, an enhanced recovery protocol based on pre-operative rehabilitation was implemented and its effect was explored.@*METHODS@#A prospective randomized controlled clinical trial was conducted, patients were recruited from January 2018 to September 2019 in this study. Patients scheduled for elective colorectal surgeries were randomly allocated to receive either standardized enhanced recovery after surgery (S-ERAS) group or enhanced recovery after surgery based on pre-operative rehabilitation (group PR-ERAS). In the group PR-ERAS, on top of recommended peri-operative strategies for enhanced recovery, formatted rehabilitation exercises pre-operatively were carried out. The primary outcome was the quality of GI recovery measured with I-FEED scoring. Secondary outcomes were quality of life scores and strength of handgrip; the incidence of adverse events till 30 days post-operatively was also analyzed.@*RESULTS@#A total of 240 patients were scrutinized and 213 eligible patients were enrolled, who were randomly allocated to the group S-ERAS (n = 104) and group PR-ERAS (n = 109). The percentage of normal recovery graded by I-FEED scoring was higher in group PR-ERAS (79.0% vs. 64.3%, P 0.050).@*CONCLUSIONS@#Peri-operative rehabilitation exercise might be another benevolent factor for early recovery of GI function and life of quality after colorectal surgery. Newer, more surgery-specific rehabilitation recovery protocol merits further exploration for these patients.@*TRIAL REGISTRATION@#ChiCTR.org.cn, ChiCTR-ONRC-14005096.

Delayed-or non-healing wounds caused by trauma, surgical procedures, acute diseases, or chronic diseases, and proli-ferating scar have a serious impact on patients' quality of life and increase the economic and psychological burden on their families. Therefore, how to accelerate wound healing and obtain satisfactory aesthetic results is of great concern to researchers and is an urgent clinical problem to be solved. In recent years, the mechanisms of Chinese medicinal materials in accelerating wound healing and inhi-biting scar formation by regulating cytokines have been clarified, which provides a scientific basis for revealing the efficacy of Chinese medicinal materials against clinical trauma. This review focuses on the therapeutic effects of active ingredients, extracts, and topical preparations of Chinese medicinal materials through regulating cytokines in the inflammation, proliferation, and remodeling phases of wound healing. It is expected to provide evidence for the application of Chinese medicinal materials in wound therapy.

ABSTRACT
Objective: To evaluate the feasibility of the endoscopic transnasal approach (ETA) and to analyze the outcomes and factors of this surgical technique in the management of the tumor invading the anterior skull base. Methods: A retrospective analysis was performed on 42 patients (31 males and 11 females, with mean age of 49 years) with sinonasal tumor invading the anterior skull base, who underwent ETA from June 2015 to April 2019 in Eye, Ear, Nose and Throat Hospital of Fudan University. Pathologically, there were 15 cases of squamous carcinoma (14 patients with T4bN0M0 and 1 patient with T4bN1M0) and 27 of olfactory neuroblastomas with Kadish stage C. Anterior skull base reconstruction was performed using the vascular pedicled nasoseptal mucoperiosteal flap and fascia lata. Brain non-contrast-enhanced CT was performed on the first postoperative day to exclude massive pneumocephalus, relevant brain edema and subarachnoid hemorrhage. Sinonasal contrast-enhanced MR was performed to assess the extent of the tumor removal. Kaplan-Meier analysis was used to calculate the overall survival (OS) and Cox multivariate regression analysis was used to determine the prognostic factors. Results: The mean duration of the surgery was 452 minutes. Total resection was performed in 36 patients (85.7%), subtotal resection in 2 patients (4.8%) with orbital involvement, partial resection in one patient (2.4%) with injury of the internal carotid artery. One patient (2.4%) underwent the second resection because of the tumor residual, two patients (4.8%) with unsure tumor residual. Mean follow-up was 20 months, with 17 months of median follow-up. One-, two-and three-year overall survival was 86.5%, 76.9% and 64.5%, respectively. For squamous carcinoma, one-, two-and three-year overall survival was 86.2%, 86.2% and 57.4%, respectively. For olfactory neuroblastomas, One-, two-and three-year overall survival was 86.9%, 75.3% and 67.8%, respectively. Multivariate analysis showed that tumor residual (P=0.001) and recurrence (P<0.01) were independent prognostic factors for survival. Conclusions: The ETA is safe and feasible in selected patients with sinonasal tumor invading the anterior skull base. Tumor residual and recurrence are independent prognostic factors for survival.

ABSTRACT
BACKGROUND@#Innovative coronavirus disease 2019 (COVID-19) vaccines, with elevated global manufacturing capacity, enhanced safety and efficacy, simplified dosing regimens, and distribution that is less cold chain-dependent, are still global imperatives for tackling the ongoing pandemic. A previous phase I trial indicated that the recombinant COVID-19 vaccine (V-01), which contains a fusion protein (IFN-PADRE-RBD-Fc dimer) as its antigen, is safe and well tolerated, capable of inducing rapid and robust immune responses, and warranted further testing in additional clinical trials. Herein, we aimed to assess the immunogenicity and safety of V-01, providing rationales of appropriate dose regimen for further efficacy study.@*METHODS@#A randomized, double-blind, placebo-controlled phase II clinical trial was initiated at the Gaozhou Municipal Centre for Disease Control and Prevention (Guangdong, China) in March 2021. Both younger (n = 440; 18-59 years of age) and older (n = 440; ≥60 years of age) adult participants in this trial were sequentially recruited into two distinct groups: two-dose regimen group in which participants were randomized either to follow a 10 or 25 μg of V-01 or placebo given intramuscularly 21 days apart (allocation ratio, 3:3:1, n = 120, 120, 40 for each regimen, respectively), or one-dose regimen groups in which participants were randomized either to receive a single injection of 50 μg of V-01 or placebo (allocation ratio, 3:1, n = 120, 40, respectively). The primary immunogenicity endpoints were the geometric mean titers of neutralizing antibodies against live severe acute respiratory syndrome coronavirus 2, and specific binding antibodies to the receptor binding domain (RBD). The primary safety endpoint evaluation was the frequencies and percentages of overall adverse events (AEs) within 30 days after full immunization.@*RESULTS@#V-01 provoked substantial immune responses in the two-dose group, achieving encouragingly high titers of neutralizing antibody and anti-RBD immunoglobulin, which peaked at day 35 (161.9 [95% confidence interval [CI]: 133.3-196.7] and 149.3 [95%CI: 123.9-179.9] in 10 and 25 μg V-01 group of younger adults, respectively; 111.6 [95%CI: 89.6-139.1] and 111.1 [95%CI: 89.2-138.4] in 10 and 25 μg V-01 group of older adults, respectively), and remained high at day 49 after a day-21 second dose; these levels significantly exceed those in convalescent serum from symptomatic COVID-19 patients (53.6, 95%CI: 31.3-91.7). Our preliminary data show that V-01 is safe and well tolerated, with reactogenicity predominantly being absent or mild in severity and only one vaccine-related grade 3 or worse AE being observed within 30 days. The older adult participants demonstrated a more favorable safety profile compared with those in the younger adult group: with AEs percentages of 19.2%, 25.8%, 17.5% in older adults vs. 34.2%, 23.3%, 26.7% in younger adults at the 10, 25 μg V-01 two-dose group, and 50 μg V-01 one-dose group, respectively.@*CONCLUSIONS@#The vaccine candidate V-01 appears to be safe and immunogenic. The preliminary findings support the advancement of the two-dose, 10 μg V-01 regimen to a phase III trial for a large-scale population-based evaluation of safety and efficacy.@*TRIAL REGISTRATION@#http://www.chictr.org.cn/index.aspx (No. ChiCTR2100045107, http://www.chictr.org.cn/showproj.aspx?proj=124702).

ABSTRACT
Alongside the social and economic development in China, medical risks, economic risks, and legal risks rise as well in the management of public hospitals. However, the capabilities of these hospitals in prevention and control of medical risks and disposal of legal affairs fall far behind the increasingly complex legal affairs. In this consideration, the authors introduced their innovative practice in taking legal actions for prevention and control of medical risks in the hospital, analyzed the problems found in medical legal affairs, and put forward specific suggestions to promote the standardization and modernization of hospital legal affairs.
ABSTRACT
Objective • To explore the reliability and validity of self-rated Family Burden Scale (FBS) evaluating caregiver burden in families of the patients with anorexia nervosa (AN). Methods • The study included female AN patients (n=103) treated in the Eating Disorder Center of Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine from Jul. 2017 to Jul. 2019 and their caregivers (parents, n=148). General demographic information of the patients and their caregivers, the course of illness and body mass index (BMI) of patients, and the time each caregiver spent in caring for the patient per day were recorded. FBS, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and the MOS item short form health survey (SF-36) were self-rated by the caregivers. One-third of the caregivers were selected by random number method for FBS rating by specialists. The reliability of the scale was evaluated by calculating Cronbach's α coefficient, self-rating and other-rating consistency and the consistency between husband and wife (41 couples). The validity of the scale was evaluated by calculating the correlation of FBS score with the course of disease, patients' BMI, the time spent in caring per day, scores of BAI and BDI, and vitality, social function, role-emotion and mental health domain of SF-36. Results • The Cronbach's α coefficient of FBS was 0.921, the correlation coefficient between self-rating and other-rating by specialists was 0.705 (P=0.000), and the correlation coefficient of consistency score between couples was 0.547 (P=0.000). FBS score showed no correlation with the course of disease, %BMI and the time spent in caring per day. Scores of BAI and BDI, and vitality, social function, role-emotion and mental health domain of SF-36 showed low correlation with FBS score (all P<0.05). Conclusion • Self-rated FBS shows good reliability when used in families of AN patients. The validity is not as ideal, which suggests further revision of the scale.
ABSTRACT
Objective@#To compare the curative effect of three different surgical methods: peritoneal varicocele ligation, peritoneal single-port laparoscopy and microscopy on varicocele.@*Methods@#Retrospective analysis of the case data of 150 patients with varicocele treated in the Affiliated Hospital of Xuzhou Medical University from September 2016 to September 2018. The average age was 24.5 years, and the age range was 22-30 years. The patients were divided into three groups according to different surgical methods: open group, laparoscopy group and microscope group, with 50 cases in each group. Patients in the open group were treated with retroperitoneal spermatic cord ligation. Patients in the laparoscopic group were treated with single-hole laparoscopic laparoscopic surgery. Patients in the microscope group were treated with microscope surgery. Operation time, postoperative hospitalization time, hospitalization cost reserved arteries, surgical complications (such as testicular hydrocele, scrotal edema, epididymitis, testicular atrophy), recurrence, and semen quality improvement were compared between three groups. Measurement data were expressed as mean ± standard deviation(Mean±SD), the two comparisons used the t test, the comparison between the three groups used the analysis of variance, and the comparison between the count data groups using the Chi-square test.@*Results@#The operation time of the patients in the microscope group [(52.52 ± 4.29) min] was longer than that of the open group [(36.60±3.69) min] and the laparoscopic group [(39.54±2.87) min]. The difference between the two groups was statistically significant (P<0.05); but the postoperative hospitalization time and hospitalization cost of patients in the microscope group [(2.16±0.95) d, (5 251 ± 300) yuan] were higher than those in the open group [(3.80±0.78) d, (64 75±415) yuan)]and the laparoscopic group [(3.28±1.01)d, (7 379±273) yuan] . The results of pairwise comparison showed that the difference between the microscope group, the open group and the laparoscopic group was statistically significant (P<0.05). Arterial preservation in the microscope group [47(94.0%)] were compared with the open group [35 (70.0%)], and laparoscopic group [30(60.0%)] had obvious advantages. Pairwise comparison results showed that the comparison between the microscope group and the open group and the laparoscopic group was statistically significant (P<0.05). After follow-up for six months, 2 cases were lost to follow-up in the microscope group, 1 cases were lost to the open group, and 5 case was lost to the unilateral laparoscopic group. 2(4.2%) patients had complications in the microscope group, and 14 (28.6%) patients had complications in the open group; 9 (20.0%) patients had complications in the laparoscopic group, and the total incidence of complications showed a pairwise comparison, the difference between the microscope group, the open group and the laparoscopic group was significant (P<0.05). The recurrence rate in the microscope group was 2.1% (1/48), the recurrence rate in the open group was 18.4% (9/49), and the recurrence rate in the laparoscopic group was 13.3% (6/45); the recurrence rate was compared in pairs, the difference between the microscope group, the open group and the laparoscopic group was significant (P<0.05) . The improvement rate of semen quality in the microscope group was 68.8% (33/48), the open group was 42.9%(21/49), the laparoscopic group was 55.6%(25/45), pairwise comparison results showed that the microscope group compared with the open group and laparoscopy group, the difference were statistically significant (P<0.05).@*Conclusions@#Microscopic surgery has less trauma, faster postoperative recovery, shorter operation cost and hospitalization time. Postoperative complications and recurrence, and improved semen quality are all superior to open spermatic vein ligation and single-hole umbilical laparoscopic surgery, it is a safe and effective way to treat varicocele.
ABSTRACT
Objective::Based on gene array technology, gene set enrichment analysis (GSEA) and immune infiltration analysis were performed on chip data of intracranial aneurysm (IA) mRNA expression profile, in order to provide theoretical basis for understanding the formation mechanism of IA. Method::The GSE75436 raw data were obtained from the gene expression omnibus (GEO). GSEA of biological process (BP) in gene ontology (GO) and Kyoto gene and genome encyclopedia (KEGG) signaling pathways were analyzed for gene expression profile by R software. The CIBERSORT deconvolution method was used to analyze the infiltration ratio of 22 types of immune cells in the expression profile. And COREMINE database was used to predict traditional Chinese medicines (TCMs), which were significant correlation with the enrichment result. Result::The GSEA results showed that the changes in gene expression of IA samples mainly involved in the regulation of cytokines, activation and differentiation of leukocyte, inflammatory immune response and other processes. The infiltration matrix analysis of immune cells showed that mast cells resting and neutrophils were significantly reduced in IA samples. The comparison of paired samples showed that mast cells and natural killer cells (NK cells) were significantly activated in the IA samples of the same individual, while neutrophils and T cells CD4 naive were significantly reduced. Through COREMINE prediction, it was found that Stephaniae Tetrandrae Radix was correlated with the activation of granulocytes, Sapindi Mukorossi Semen and Pistaciae Chinensis Cortex were correlated with the activation of neutrophils, Trichosanthis Semen, Paeoniae Radix Alba and Ligustri Lucidi Fructus were correlated with the cytotoxicity mediated by NK cells. Conclusion::Activation of mast cells and NK cells are closely associated with the occurrence and development of IA. The inflammatory immune processes and pathways such as nucleotide-binding oligomerization domain (NOD)-like receptor (NLR) signaling pathway and cytotoxicity mediated by NK cells may be important factors in the pathogenesis of IA, and TCMs such as Stephaniae Tetrandrae Radix may be the potential molecular drug sources.
