ObjectiveTo explore the potential mechanism of Xiaoqinglong Decoction （小青龙汤， XD） in the treatment of allergic rhinitis. MethodsForty-five rats were randomly assigned to a control group， a model group， a loratadine group， low-， medium- and high-dose XD groups， and low-， medium- and high-dose Mahuang Decoction and Cang'erzi Powder （麻黄汤合苍耳子散， MDCP） groups. Except for the control group， rats were administered with ovalbumin （OVA） and aluminum hydroxide via intraperitoneal injection for 14 days to establish an allergic rhinitis model. After the 14th-day injection， nasal stimulation was continued with 20 μl of 10% OVA solution to maintain the model. Rats in the control group and the model group received 10 ml/（kg·d） of saline， whereas those in the loratadine group were administered with 0.9 mg/（kg·d） of loratadine. The low-， medium- and high-dose XD groups were administered XD at the dose of 2.7， 5.4， and 10.8 g/（kg·d）， respectively. The low-， medium- and high-dose MDCP groups were administered MDCP at the dose of 2.43， 4.86， and 9.72 g/（kg·d）， respectively. All treatments were administered by gavage once daily for 7 consecutive days. One hour after the final gavage， nasal symptom scores were recorded for all group of rats. The next day， serum levels of immunoglobulin E （IgE）， interleukin-4 （IL-4）， and interleukin-13 （IL-13） were measured. HE staining was used to observe the pathological morphology of the nasal mucosal tissue. Quantitative reverse transcription PCR （RT-qPCR） and Western Blot were performed to assess mRNA and protein expression of thymic stromal lymphopoietin （TSLP） and OX40 ligand （OX40L） in the nasal mucosa. ResultsCompared to the control group， total nasal symptom score in the model group significantly increased （P＜0.01）. HE staining revealed disrupted and adhered cilia， thickened basement membranes， and extensive inflammatory cell infiltration in the nasal mucosa. Serum levels of total IgE， IL-4， and IL-13， as well as TSLP and OX40L mRNA and protein expression in the nasal mucosa， were significantly elevated in the model group （P＜0.05 or P＜0.01）. Compared to the model group， the total nasal symptom scores in all drug intervention groups were significantly reduced； the serum total IgE levels in the loratadine group， the low- and medium-dose XD groups， and the low- and high-dose MDCP groups were significantly reduced； and the serum levels of IL-4 and IL-13 in the high-dose XD group and the high-dose MDCP group decreased （P＜0.05 or P＜0.01）. Nasal mucosal structure was improved. Except for the low-dose MDCP group， all other intervention groups showed a significant reduction in TSLP and OX40L mRNA expression in the nasal mucosa （P＜0.01）. All doses of XD and the medium- and high-dose MDCP groups significantly decreased the protein levels of TSLP and OX40L （P＜0.05）. The medium-dose XD group exhibited more improvement of nasal symptom scores and greater suppression of expression of TSLP and OX40L mRNA， and TSLP protein levels compared to the loratadine group （P＜0.05）. ConclusionXD may protect nasal mucosa of rats and alleviate allergic rhinitis by suppressing the TSLP/OX40L pathway， thereby attenuating Th2-mediated immune responses.

Objective Chronic atrophic gastritis(CAG)is often accompanied by intestinal flora disorder and intestinal symptoms,forming the phenomenon of"stomach disease involving intestine".This study explored the dynamic correlation between intestinal symptoms and qi-stagnation degree in patients with CAG qi-stagnation syndrome and analyzed the characteristics of gut microbiota from the perspective of"spleen-stomach system serving as the pivotal hub of qi movement"in TCM.Methods According to the syndrome element differentiation method,410 patients with CAG were divided into four groups:non-qi-stagnation group,mild qi-stagnation group,moderate qi-stagnation group and severe qi-stagnation group.Correlation analysis and 16S intestinal flora sequencing technology were used to analyze the correlation and differential flora between the degree of CAG qi-stagnation and intestinal symptoms.Results Patients with CAG qi-stagnation syndrome were often accompanied by intestinal symptoms such as frequent flatulence,poor defecation and alternating loose-constipated stools.The frequency of cases was significantly positively correlated with the degree of qi-stagnation"non-mild-moderate-severe"(P<0.05).There was a difference in the abundance of gut microbiota between the four groups of CAG qi-stagnation none,mild,moderate and severe.The relative abundance of Streptococcus,Subdoligranulum,Eubacterium_coprostanoligenes_group and Haemophilus was positively correlated with the degree of qi-stagnation.The relative abundance of Ruminococcus_torques_group and Butyricicoccus showed a negative correlation,and Haemophilus was statistically significant among the four groups(P<0.05).Conclusion This study can provide clinical evidence and micro-mechanism for the connotation of"gastrointestinal co-morbidities"and"different diseases with the same syndrome",which may open up new ideas for clinical diagnosis and treatment.

Objective To explore the mechanism by which electroacupuncture improves ocular surface inflammation in dry eye mice.Methods 30 SPF-grade healthy male ICR mice were randomly divided into a blank group,a model group,a sham electroacupuncture group,a western medicine group and an electroacupuncture group,with 6 mice in each group.Mice in the blank group and other four groups were subcutaneously injected 200 μL of sterile physiological saline and 200 μL of scopolamine hydrobromide(0.5 mg dissolved in 0.2 mL of sterile physiological saline)at 8:00,11:00,14:00,and 17:00 every day for 35 consecutive days,respectively.From the 22nd day,mice in the sham electroacupunc-ture group were given blunt scalp acupuncture intervention at bilateral Jingming and Taiyang points,without subcutaneous penetration.In the western medicine group,fluorometholone eye drops were applied to both eyes of the mice at 8:00,13:00,and 18:00 daily,with 1 drop each time.Mice in the electroacupuncture group were given electroacupuncture in-tervention,with the same acupoint location and acupuncture time as the sham electroacupuncture group.The electroacu-puncture frequency was 2 Hz/20 Hz,the waves were sparse-dense and the intensity was 1 mA,once a day for 15 min.All groups were intervened for 14 days.The corneal fluorescein(FL)staining scores of mice in each group were detected be-fore modeling,after modeling,and after intervention.The corneal tissue morphology was observed under a light micro-scope.Immunohistochemistry staining and quantitative reverse transcription polymerase chain reaction(qRT-PCR)were used to detect the protein and mRNA expression of high mobility group box 1(HMGB1)and receptor for advanced glyca-tion end products(RAGE)in the cornea,respectively.Results The FL scores of mice in model,sham electroacupunc-ture,western medicine,and electroacupuncture groups all significantly increased after modeling and intervention,com-pared with those before modeling(all P＜0.01).The FL scores of mice in electroacupuncture and western medicine groups significantly decreased after intervention,compared with those after modeling(both P＜0.01).Compared with the model group,electroacupuncture and western medicine groups showed a significant drop in FL score after intervention(both P＜0.01).HE staining showed that after intervention,mice in electroacupuncture and western medicine groups had a basically normal number of corneal epithelial layers,no obvious shedding of epithelial cells,and neatly arranged and slightly swollen collagen fibers in the stromal layer.The relative protein expression levels of HMGB1 and RAGE in the corneal tissue of both model and sham electroacupuncture groups were significantly higher than those of the blank group(allP＜0.01).The rela-tive protein expression levels of HMGB1 and RAGE in the corneal tissue of both electroacupuncture and western medicine groups were significantly lower than those of the model group(all P＜0.01).The relative mRNA expression levels of HMGB1 and RAGE in the corneal tissue of both model and sham electroacupuncture groups were significantly higher than those of the blank group(all P＜0.01).The relative mRNA expression levels of HMGB1 and RAGE in the corneal tissue of both electroacupuncture and western medicine groups were significantly lower than those of the model group(all P＜0.01).Conclusion Electroacupuncture mitigates corneal epithelial injury,reduces the expression of HMGB1 in the cor-neal tissue,inhibits the binding of HMGB1 and RAGE,and ultimately alleviates ocular surface inflammation responses of dry eye mice.

Objective:To investigate the etiological diagnostic value of metagenomic sequencing in central nervous system (CNS) infectious diseases.Methods:A total of 170 patients with central nervous system infection admitted to the First Affiliated Hospital of Zhengzhou University from January 2018 to June 2020 were selected as the study subjects according to inclusion and exclusion criteria. General clinical data and pathogen test results were collected. All included patients underwent routine examination and mNGS test, and were divided into the conventional method test group and mNGS test group according to the test results. The measurement data conforming to normal distribution were represented by ± s; The measurement data that did not conform to normal distribution were represented by median and interquartile range. The classification data were expressed by the number of cases and percentage( n,%), and were compared by χ2 test or Fisher's exact test. Consistency test was represented by Kappa value. The detection of pathogenic microorganisms by the two methods and the rule of pathogen spectrum were compared and analyzed. Results:The overall positive rate of mNGS in CNS infectious diseases was higher than that of conventional methods (58.23% vs. 18.82%), and the difference was statistically significant ( P<0.01). Among the 20 samples which were both positive by the two methods, 10 cases were completely pathogenic, 5 cases were partially consistent and 5 cases were completely inconsistent. In the detection of tuberculous nervous system infection, the positive rates were 66.7%, 53.8%, 44.0%, 40.0%, 4.0% in blood T-SPOT, cerebrospinal fluid mNGS, ADA, Mycobacterium tuberculosis DNA and tuberculous specific antibody, respectively. The positive rate of acid-fast staining was 0. The positive rate of mNGS combined with conventional method was 80.8%. Conclusions:The detection rate of mNGS in CNS infection is better than that of conventional methods. However, it does not show obvious superiority in the detection rate of Mycobacterium tuberculosis associated nervous system infection. In general, mNGS detection of pathogenic bacteria is more extensive, which is conducive to a thorough and comprehensive understanding of the bacterial characteristics of central nervous system infection. The combination of the two methods can make up for the deficiency of clinical routine detection to a certain extent, and can maximize the detection rate.

Objective To explore a method of nursing post evaluation in the physical examination center and provide basis for performance appraisal and compensation management. Methods A total of 13 nursing posts were evaluated by 23 staff members in physical examination center and 7 evaluators from other departments of the hospital between June and August 2015 using Hay′s guide chart-profile method. Results The highest score of 13 nursing posts was 805. 4 and the lowest score was 80. 1. The average score of nursing posts in the morning and afternoon were (230. 9 ± 65. 6) and (190. 6 ± 85. 1). There was no significant difference between groups (t =0. 929,P =0. 375). Conclusions Hay′s guide chart-profile method can be used to compare the relative value of different nursing posts in physical examination center and can provide basis for performance appraisal and compensation management.
