Fitting Degrees of Animal Models of Diarrhea-irritable Bowel Syndrome with Clinical Characteristics of Western Medicine and Traditional Chinese Medicine / 中国实验方剂学杂志

Diarrhea-irritable bowel syndrome （IBS-D） is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated， effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine （TCM） and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D， we discovered that rats were the preferred animals for modeling， and the models were mainly induced by single factors， double factors， or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition， the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency， and few models were established for the syndromes of spleen-kidney Yang deficiency， spleen-stomach dampness-heat， spleen deficiency and dampness excess， and cold and heat in complexity. Therefore， it is essential to improve the existing or develop new animal models of IBS-D in the future， so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.

Characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma(PACG).METHODS: A total of 48 first-degree relatives of PACG patients aged 40-60 who were treated in the Affiliated Eye Hospital of Nanchang University from September 2020 to October 2022 were selected as the observation group. Additionally, 40 cases(40 eyes)of healthy individuals without glaucoma and family history of glaucoma at the same age group were collected as the control group. They were divided into younger group(40-49 years old)and elder group(50-60 years old). All subjects were examined with ultrasound biomicroscopy(UBM)and were measured using camera measure software. The parameters mainly included anterior chamber depth(ACD), anterior chamber area(ACA), anterior chamber width(ACW), anterior segment depth(ASD), angle open distance(AOD500), trabecular iris angle(TIA), trabecular iris area(TISA500), lens vault(LV), iris curve(IC), iris thickness(IT500), scleral ciliary process angle(SCPA), and iris ciliary process distance(ICPD).RESULTS: ACD, ACA, AOD500, TISA500 and TIA in the observation group were lower than those of the control group, and LV and IC were higher than those of the control group(all P<0.05). ACD, ACA, AOD500, TISA500, and TIA of the elder group were lower than those in the age-matched control group, while LV and IC were larger than those of the age-matched control group(all P<0.05). ACD, AOD500, TISA500, and TIA of the younger observation group were smaller than those of the age-matched control group, but LV and IC were significantly larger than those of the age-matched control group(all P<0.05). ACD, ACA, AOD500, TISA500 and TIA of the elder observation group were significantly lower than those of the younger observation group, and LV and IC were significantly larger than those of the younger observation group(all P<0.05). There was a difference in the distribution of ACD between the observation group and the control group(P<0.05), and the proportion of moderate to severe shallow anterior chambers was 10 times that of the control group. Correlation analysis showed that TISA500 was positively correlated with ACD and ACA, and negatively correlated with LV and IC, and TISA500 was mainly influenced by LV. IC had a positive correlation with LV and a negative correlation with ACD and ACA.CONCLUSION: First-degree relatives of PACG with normal axial length have a high risk of angle closure. The anterior segment structures of first-degree relatives of PACG are more crowded than normal individuals, and the lens forward shift may be the initial influencing factor for narrow angle.

Meta-analysis of the efficacy of invisible orthodontic appliances for maxillary molar distalization in adult patients / 口腔疾病防治

Objective@#To evaluate the clinical efficacy of invisible orthodontic appliances without brackets for the distal movement of maxillary molars to improve the ability of orthodontists to predict treatment outcomes.@*Methods@#Web of Science, Cochrane Library, Embase, PubMed, Wanfang Database, CNKI Database, and VIP Database were searched for studies investigating the efficacy of invisible orthodontic appliances for distal movement of maxillary molars in adult patients and published from database inception to August 1, 2023. A total of three researchers screened the studies and evaluated their quality and conducted a meta-analysis of those that met quality standards.@*Results@#This study included 13 pre- and postcontrol trials with a total sample size of 281 patients. The meta-analysis revealed no significant differences in the sagittal or vertical parameters of the jawbone after treatment when compared with those before treatment (P>0.05). The displacement of the first molar was MD=-2.34, 95% CI (-2.83, -1.85); the displacement was MD=-0.95, 95% CI (-1.34, -0.56); and the inclination was MD=-2.51, 95% CI (-3.56, -1.46). There was a statistically significant difference in the change in sagittal, vertical, and axial tilt of the first molar before and after treatment. After treatment, the average adduction distance of the incisors was MD=-0.82, 95% CI (-1.54, -0.09), and the decrease in lip inclination was MD=-1.61, 95% CI (-2.86, -0.36); these values were significantly different from those before treatment (P<0.05).@*Conclusion@#Invisible orthodontic appliances can effectively move the upper molars in a distal direction and control the vertical position of the molars. When the molars move further away, there is some degree of compression and distal tilt movement, which is beneficial for patients with high angles. The sagittal movement of incisors is beneficial for improving the patient's profile.

Animal Models of Ovarian Cancer Based on Characteristics of Clinical Symptoms of Traditional Chinese and Western Medicine / 中国实验方剂学杂志

ObjectiveOvarian cancer is the third most common gynecologic cancer worldwide， with the second highest mortality rate among gynecologic cancers， and age-standardized rates are gradually increasing in many low- and middle-income countries. At present， its etiology and pathogenesis are not clear. There are no obvious symptoms in the early stage， and when the symptoms become obvious， it often indicates the advanced stage. The 5-year survival rate of the advanced stage is only 17%， which poses a great threat to women's health. Therefore， an in-depth study of the etiology and pathogenesis of ovarian cancer is very important to the exploration of prevention and treatment methods for ovarian cancer. Based on the clinical characteristics of ovarian cancer in traditional Chinese and Western medicine， and combined with the existing evaluation methods of animal models， this study evaluated the animal model of ovarian cancer， and provided analysis and suggestions. MethodThis study searched China National Knowledge Infrastructure （CNKI）， Wanfang data， VIP information database， and PubMed database using the keywords "ovarian cancer" and "animal model"， excluded the articles that did not meet the criteria， and then classified the remaining studies. Combined with the clinical diagnostic criteria of Western medicine and traditional Chinese medicine syndrome differentiation， the related indicators of ovarian cancer animal models were assigned and the degree of agreement was evaluated. ResultThe use of the transplanted animal model exhibited the highest frequency， followed by that of the induced model. The degree of agreement of traditional Chinese medicine for each model was lower than that of Western medicine. The induced ovarian cancer model had a high degree of clinical agreement and was similar to human ovarian cancer in terms of tumor growth pattern， disease progression and complications， which is an ideal animal model of ovarian cancer. Although this animal model can simulate the etiology and pathogenesis of ovarian cancer to a certain extent and reflect some indicators of traditional Chinese and Western medicine， it lacks differentiation of traditional Chinese medicine syndromes. ConclusionOn the basis of the original model， the animal model of ovarian cancer was added with Qi deficiency syndrome， blood deficiency syndrome， Qi stagnation syndrome， blood stasis syndrome， heat-toxin syndrome， and Yang deficiency syndrome to establish an animal model combining traditional Chinese medicine disease and syndrome of ovarian cancer， which could better simulate the clinical actual situation of traditional Chinese and Western medicine and lay a solid foundation for the study of integrated traditional Chinese and Western medicine for the treatment of ovarian cancer.

¿Es diferente la conectividad estructural en niños y adolescentes familiares de pacientes con trastorno bipolar? Una revisión narrativa según estudios con DTI

Introducción: El trastorno afectivo bipolar (TAB) se ha asociado con una disminución de la integridad de la sustancia blanca. Los estudios con imágenes con tensor de difusión (DTI) han permitido elucidar con una mayor calidad estos cambios. Debido a la gran heredabilidad del TAB, se han realizado estudios en familiares de pacientes con TAB acerca de la integridad de la sustancia blanca, y se ha encontrado que la conectividad estructural también puede estar afectada. Dicha alteración se ha propuesto como un potencial biomarcador de vulnerabilidad a este trastorno. Sin embargo, los estudios en niños y adolescentes son pocos. Objetivo: Revisar la literatura sobre los cambios en la integridad de la sustancia blanca determinados mediante DTI en niños y adolescentes con alto riesgo. Resultados: Se describe la conectividad estructural cerebral en la población pediátrica en estudios que utilizaron DTI. Se describen los cambios en el proceso de mielinización desde su evolución dentro del neurodesarrollo normal hasta los hallazgos en la anisotropía fraccional (AF) en pacientes con TAB y los familiares en alto riesgo. Conclusiones: Los estudios demuestran que tanto pacientes con TAB como sus familiares en riesgo presentan disminución de la AF en regiones cerebrales específicas. Los estudios en niños y adolescentes con riesgo familiar de TAB señalan una AF reducida en tractos axonales implicados en funciones emocionales y cognitivas. La disminución de la AF puede considerarse como un biomarcador de vulnerabilidad al TAB.

Introduction: Bipolar disorder (BD) has been associated with a decrease in white matter integrity. Diffusion tensor imaging (DTI) studies have enabled these changes to be elucidated with higher quality. Due to BD's high heritability, some studies have been conducted in relatives of BD patients looking at white matter integrity, and have found that structural connectivity may also be affected. This alteration has been proposed as a potential BD biomarker of vulnerability. However, there are few studies in children and adolescents. Objective: To conduct a review of the literature on changes in white matter integrity determined by DTI in high-risk children and adolescents. Results: Brain structural connectivity in the paediatric population is described in studies using DTI. Changes in the myelination process from its evolution within normal neurodevelopment to the findings in fractional anisotropy (FA) in BD patients and their high-risk relatives are also described. Conclusions: Studies show that both BD patients and their at-risk relatives present a decrease in FA in specific brain regions. Studies in children and adolescents with a high risk of BD, indicate a reduced FA in axonal tracts involved in emotional and cognitive functions. Decreased FA can be considered as a vulnerability biomarker for BD.

Depth of cure, mechanical properties and morphology of dual-cure bulk-Fill composites / Profundidad de curado, propiedades mecánicas y morfología de resinas compuestas duales

This study evaluated selected structural and physical properties, such as degree of conversion (DC), Vickers hardness (VHN), and compression strength (CS), of three new dual-cure bulk-fill resin-based composites (RBCs; ACTIVA, HyperFIL, and Fill-Up) and compared them to those of a conventional RBC (Filtek Z250) at three clinically relevant depths. Samples (n=180) were prepared in three depths (2,4, and 6mm). Fourier-transform infrared spectroscopy (FTIR) analysis and VHN and CS tests were performed. The DC value was calculated by considering the relative change in the aliphatic C=C peaks. The fractured surfaces of representative samples were characterized using scanning electron microscopy (SEM). Data were statistically evaluated using two-way analysis of variance and post hoc Bonferroni tests (p<0.05). According to the VHN results, Filtek Z250 showed the highest bottom/top hardness ratio (97.94±1.01) at 2mm thickness and ACTIVA showed the lowest bottom/top hardness ratio (43.48±5.64) at 6mm thickness (p<0.001). According to the FTIR results, the DC decreased with increasing thickness in all materials (p<0.05). Filtek Z250 showed the highest (301±12.4 MPa) and ACTIVA exhibited the lowest (232±17.2 MPa) CS values at 2mm thickness (p<0.05). The lowest CS values were obtained for ACTIVA, and the highest values were obtained for Filtek Z250 for samples with thicknesses of 4 and 6mm, respectively (p<0.05). The structural features of restorative composites, such as the resin chemistry and filler type and content, and the operational parameters (i.e., material thickness and curing conditions) strongly affect crosslinking reactions and thus the DC, VHN, and CS values.

Este estudio evaluó propiedades físicas y estructurales, como el grado de conversión (DC), la dureza Vickers (VHN) y la resistencia a la compresión (CS), de tres nuevos compósitos a base de resina de curado dual tipo bulk (RBC; ACTIVA , HyperFIL y Fill-Up) y los comparó con los de una resina compuesta convencional (Filtek Z250) en tres profundidades clínicamente relevantes. Se prepararon muestras (n=180) en tres profundidades (2,4 y 6mm). Se realizaron análisis de espectroscopia infrarroja por transformada de Fourier (FTIR) y pruebas VHN y CS. El valor de DC se calculó considerando el cambio relativo en los picos alifáticos C=C. Las superficies fracturadas de muestras representativas se caracterizaron mediante microscopía electrónica de barrido (MEB). Los datos se evaluaron estadísticamente mediante análisis de varianza de dos vías y pruebas post hoc de Bonferroni (p<0,05). De acuerdo con los resultados de VHN, Filtek Z250 mostró la relación de dureza inferior/superior más alta (97,94±1,01) con un espesor de 2mm y ACTIVA mostró la relación de dureza inferior/superior más baja (43,48±5,64) con un espesor de 6mm (p<0,001). De acuerdo con los resultados de FTIR, la DC disminuyó al aumentar el espesor en todos los materiales (p<0,05). Filtek Z250 mostró los valores de CS más altos (301±12,4 MPa) y ACTIVA los más bajos (232±17,2 MPa) a 2mm de espesor (p<0,05). Los valores más bajos de CS se obtuvieron para ACTIVA y los valores más altos para Filtek Z250 para muestras con espesores de 4 y 6mm, respectivamente (p<0,05). Las características estructurales de las resinas compuestas de restauración, como la química; además del tipo y contenido del relleno, y los parámetros operativos (es decir, el espesor del material y las condiciones de curado) afectan en gran medida las reacciones de interacción química y, por lo tanto, los valores de DC, VHN y CS.

Implante de marcapasos a través de la vena cava superior izquierda persistente por ausencia de vena cava superior derecha. Reporte de un caso / Pacemaker implantation through the persistent left superior vena cava due to the absence of the right superior vena cava. Report of a case / Implante de marcapasso pela veia cava superior esquerda persistente devido à ausência da veia cava superior direita. Relato de um caso

Resumen: Introducción: la persistencia de la vena cava superior izquierda (PVCSI) tiene una prevalencia de 0.21% en la población general. Presentación del caso: masculino de 67 años de edad diagnosticado con bloqueo auriculoventricular (AV) de tercer grado y que requirió colocación de marcapasos; sin embargo, debido a la ausencia de la vena cava superior derecha, corroborado por angiotomografía, se colocó marcapasos definitivo a través de la vena cava superior izquierda persistente. Conclusión: la persistencia de la vena cava superior izquierda (PVCSI) es la anomalía venosa torácica más común. Puede causar una serie de síntomas clínicamente significativos, incluso en un corazón con anatomía normal. La colocación de marcapasos dificulta la fijación del electrodo debido al recorrido tortuoso que genera.

Abstract: Introduction: the persistence of the left superior vena cava (PLSVC) has a prevalence of 0.21% in the general population. Case presentation: 67-year-old male diagnosed with third-degree AV block, requiring pacemaker placement. However, due to the absence of a right superior vena cava, corroborated by CT angiography, a definitive pacemaker was placed through a persistent left superior vena cava. Conclusion: the persistence of the left superior vena cava (PLSVC) is the most common thoracic venous anomaly. It can cause a number of clinically significant symptoms, even in a heart with normal anatomy. Pacemaker placement makes electrode fixation difficult due to tortuous travel.

Evaluation of colloidal gold method for detection of HIV-1 antibody in the urine / 上海预防医学

ObjectiveTo verify and promote the HIV antibody urine test in a demonstration zone for HIV prevention and control in Xinjiang， and to assess the sensitivity and specificity of the test and the willingness of the volunteers， providing a basis for evaluating and determining whether it was suitable for large-scale use in the region. MethodsStratified cluster sampling was used to select the respondents in a place in Xinjiang for questionnaire survey and sample collecting. Questionnaire results were statistically described， and multivariate logistic regression analysis was used to explore the influencing factors of willingness to use HIV-1 urine test. The results of blood ELISA antibody detection method were used as a reference to calculate the specificity， sensitivity and Kappa value of urinary HIV-1 antibody in the total population and different populations. ResultsA total of 2 504 volunteers were recruited for the urine self-testing. The sensitivity of HIV-1 antibody urine test in the total population was 94.73% （54/57）， the specificity was 100% （2 447）， the positive predictive value was 100% （54/54）， and the negative predictive value was 99.88% （2 447/2 450）. The specificity of each population group was 100% when comparing different populations. The test sensitivity was 100% in pregnant women， prostitutes and drug users， 50% （1/2） in MSM subjects， with a Kappa value of 0.796. The test sensitivity was 80% （8/10） in the volunteers， with a Kappa value of 0.878. In the satisfaction survey， 73.1% population was more likely to receive urinary rapid test than the blood fast test， 93.8% of the population was willing to recommend the rapid urinary detection to other people. More than 70% of the population was satisfied with the rapid urinary detection. The multivariate logistic regression analysis showed that age， degree of education， occupation， marital status， payment method of medical expenses， and income level were the influence factors of the purchase of urine fast reagent for the self-testing （P<0.05）. ConclusionUrinary HIV-1 antibody detection method has good reliability and public satisfaction. It is suitable for large-scale use in Xinjiang.

Repair effects and mechanism of Zhixu burn ointment on deep second-degree burned model rats / 中国药房

OBJECTIVE To study the repair effect and mechanism of Zhixu burn ointment on deep second-degree burned model rats. METHODS The deep second-degree burned model was established with a temperature-controlled apparatus. The model rats were randomly divided into model group， Jingwanhong ointment group and Zhixu burn ointment high-dose， medium-dose and low-dose groups （specifications were 20 g core+20 mL wetting agent， 10 g core+20 mL wetting agent， 5 g core+20 mL wetting agent， respectively）. Another blank control group （only dehairing treatment， no modeling） was set up， with 10 rats in each group. The rats in each administration group were given corresponding drugs， the rats in the blank control group were not treated， and the rats in the model group were given normal saline once a day for 21 d. The healing of burn wounds and histomorphological changes of burned skin in each group of rats were observed， and the healing rate of wounds was calculated； the levels of vascular endothelial growth factor （VEGF）， interleukin-1β （IL-1β）， IL-6 and tumor necrosis factor-α（TNF-α） in the wound skin tissue of rats were detected by enzyme-linked immunosorbent assay； immunohistochemical method was used to detect the expression levels of VEGF and platelet endothelial cell adhesion molecule-1 （CD31） protein in burned skin tissue. RESULTS Compared with model group， the wound area of the rats in the Jingwanhong ointment and Zhixu burn ointment groups gradually decreased and healed significantly by day 21， and the wound healing rate was significantly higher （P＜0.05 or P＜0.01）； thicker new epidermal layer was seen in the skin tissue， and connective tissue and new blood vessels were significantly increased in the dermis； the expression levels of IL-1β， IL-6 and TNF-α were significantly decreased （P＜0.05 or P＜0.01）， and the expression levels of VEGF and CD31 protein were significantly increased （P＜0.05 or P＜0.01） in the burned skin tissue. CONCLUSIONS Zhixu burn ointment can repair the skin of deep second-degree burned model rats， and the mechanism may be related to reducing the inflammatory response of burn wound and promoting the angiogenesis.
