ObjectiveTo provide a basis for the establishment of an ideal animal model of allergic asthma by statistically analyzing the modeling characteristics and the selection of indicators of the available models. MethodsWe retrieved the relevant articles from China National Knowledge Infrastructure（CNKI）， VIP， Wanfang Data， SinoMed， and PubMed with "allergic asthma" as the keyword and the time interval from January 2019 to January 2024. Through integrating the literature and extracting data， we used Excel 2021 to create a personal database and sorted out the animal strains， genders， allergenic substances， modeling routes， and test indicators and methods. Excel 2021， Cytoscape 3.10.2， and SPSS Modeler 18.0 were then used to analyze the relevant characteristics of the animal models. ResultsA total of 418 articles were included in the database， and the comparative analysis showed that the most frequently used animal strain for modeling was BALB/c mice， and female animals were mostly used. The main modeling method was sensitization by intraperitoneal injection of ovalbumin （OVA）， which was combined with intranasal inhalation. The test indicators mainly included appearance signs， cellular analysis， lung histopathology， lung function indicators， and protein and gene expression in the lung. The test methods mainly involved pathological staining， enzyme-linked immunosorbent assay， immunohistochemistry， immunofluorescence， Western blot， and polymerase chain reaction（PCR） assays. ConclusionThere is no recognized modeling method or evaluation standard for the animal models of allergic asthma. Based on the results of data analysis， the OVA-induced allergic asthma model in BALB/c mice is recommended. The main criteria for evaluating the success of modeling are the general behavioral changes， the morphological changes of the airway and inflammatory cell infiltration in the lung tissue， the changes of pro-inflammatory and anti-inflammatory cytokines in the serum， and the alterations of inflammatory cells in the bronchoalveolar lavage fluid.

BACKGROUND:Currently,there are various rat models of lumbar disc herniation used in experiments,each with its own advantages and disadvantages.The most common modeling methods include autologous nucleus pulposus transplantation and annulus fibrosus puncture models.OBJECTIVE:To establish two autologous nucleus pulposus transplantation models(with spinous process and mastoid process excision and with transverse process and mastoid process excision)as well as an annulus fibrosus puncture model,and to compare and evaluate the characteristics of the three models.METHODS:Forty male adult Sprague-Dawley rats were randomly divided into four groups(n=10 per group):sham surgery group,spinous process group,transverse process group,and annulus fibrosus puncture group.In the sham surgery group,surgical preparation was performed,the skin was incised,and the spinous process was exposed,and then sutured.In the spinous process group,L5 spinous process and transverse process were excised,and two pieces of tail nucleus pulposus were placed in the intervertebral foramen.In the transverse process group,L5 transverse process and transverse process were excised,and two pieces of tail nucleus pulposus were placed in the intervertebral foramen.In the annulus fibrosus puncture group,the transverse process was excised and annulus fibrosus puncture and intervertebral disc injection of interleukin 1β were then performed.Thermal paw withdrawal latencies were tested before and after modeling.Lumbar spine MRI was performed 2 weeks after modeling.Pathological changes in the intervertebral discs were observed using hematoxylin-eosin staining and safranin-O-fast green staining.Immunofluorescence was used to observe CD68+positive expression.RESULTS AND CONCLUSION:(1)Thermal withdrawal threshold testing results showed that compared with the sham surgery group,pain sensitivity and tolerance time of rats decreased significantly after modeling(P<0.05).(2)Lumbar spine MRI images showed that the spinous process and transverse process groups had obvious protrusion of nucleus pulposus tissue,which more closely resembled MRI images of patients with common lumbar disc herniation.(3)Hematoxylin-eosin staining revealed that compared with the sham surgery group,nucleus pulposus tissues in the model groups showed varying degrees of degeneration,inflammatory cell infiltration,and degradation of spinal cord cells,with the appearance of cystic changes,among which the annulus fibrosus puncture group had the most severe pathological changes.(4)Safranin-O-fast green staining showed that compared with the sham surgery group,the boundaries of nucleus pulposus tissues in the three model groups were blurred,with extensive inflammatory reactions and varying degrees of degeneration in the annulus fibrosus.(5)CD68+immunofluorescence staining results showed that compared with the sham surgery group,the expression of CD68+in the model groups was higher and more widespread,with the annulus fibrosus puncture model showing the highest expression.All the three methods could be used to effectively establish rat models of lumbar disc herniation,with the annulus fibrosus puncture model established after excision of the transverse process being superior to the autologous nucleus pulposus transplantation model(spinous process+mastoid process),and the first two models being superior to the autologous nucleus pulposus transplantation model(transverse process+mastoid process).

Objective:To evaluate the effect of value orientation brief therapy(VBT)combined with selective serotonin reuptake inhibitors(SSRIs)on clinical symptoms,rumination,decision-making ability,and cognitive func-tion in patients with mild to moderate depression.Methods:Eighty patients meeting the DSM-5 diagnostic criteria for mild to moderate depression were randomly assigned to either a medication(SSRIs)group(36 completed)or a VBT combined group(38 completed)for a 6-week intervention.Baseline and post-intervention assessments includ-ed the Hamilton Depression Scale(HAMD),Hamilton Anxious Scale(HAMA),Ruminative Response Scale-Chi-nese Version(RRS-CV),Iowa Gambling Test(IGT),number of eye fixation(NEF),responsive search score(RSS)in exploratory eye trajectory movement were used to evaluate patients'anxiety and depression symptoms,ru-minative thinking,decision-making function,and cognitive function.Results:The VBT combined group showed sig-nificantly better therapeutic effects than the medication group(P＜0.05).Compared to baseline and the medication group,the VBT combined group had significantly lower post-intervention scores in HAMD,HAMA,symptom rumi-nation,introspective reflection,compulsive meditation,and RRS-CV total scores after intervention(Ps＜0.05),and significantly higher scores in IGT net profit scores,NEF,and RSS scores(Ps＜0.05).Compared with the medica-tion group,the VBT combined group demonstrated a greater reduction in HAMD,HAMA,symptom rumination,in-trospective reflection,compulsive meditation,and RRS-CV total scores before and after intervention(Ps＜0.05),and a larger increase in IGT net profit scores,NEF,and RSS scores(Ps＜0.05).Conclusion:VBT combined with SSRIs effectively improves the symptoms of depression,anxiety,decision-making ability,rumination thinking,and cognitive function in patients with mild to moderate depression.

Objective To investigate the preventive and therapeutic effects of vesiculation moxibustion on rat hepatic fibrosis (HF).Methods Thirty rats were randomly allocated to treatment, model and control groups, 10 rats each. A rat model of HF was made by intraperitoneal injection of carbon tetrachloride. At three weeks after model making, the treatment group was treated by vesiculation moxibustion 6 hrs twice a week, for a total of 4 weeks. Body weight, liver wet weight, liver index, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) contents, and serum and liver typeⅢ procollagen (PCⅢ), typeⅣ collagen (Ⅳ-C), hyaluronic acid (HA) and laminin (LN) contents were measured in every group of rats.Results There were statistically significant differences in HF severity grade and HF tissue collagen analysis indices between the model group of rats and the treatment group or the control group (P<0.01,P<0.05). There were statistically significant differences in body weight, liver wet weight and liver index between the model and control groups of rats (P<0.01). There were statistically significant differences in liver wet weight and liver index between the treatment and model groups of rats (P<0.01). There were statistically significant differences in serum ALT and AST contents, and serum and liver PCⅢ,Ⅳ-C, HA and LN contents between the model and control groups of rats (P<0.01,P<0.05). There were statistically significant differences in serum ALT and AST contents, and serum and liverⅣ-C, HA and LN contents between the treatment and model groups of rats (P<0.01,P<0.05). There was a statistically significant difference in serum PCⅢ content between the treatment and model groups of rats (P<0.01).Conclusion Vesiculation moxibustion has some preventive and therapeutic effects on rat hepatic fibrosis.
