ObjectiveTo investigate the effect of Tangbikang granules on oxidative stress of sciatic nerve in diabetic rats by regulating adenylate activated protein kinase/peroxisome proliferator-activated receptor γ coactivator-1α/mitochondrial Sirtuins 3 （AMPK/PGC-1α/SIRT3） signaling pathway. MethodThe spontaneous obesity type 2 diabetes model was established using ZDF rats. After modeling， they were randomly divided into high， medium， and low dose Tangbikang granule groups （2.5， 1.25， 0.625 g·kg-1·d-1） and lipoic acid group （0.026 8 g·kg-1·d-1）， and the normal group was set up. The rats were administered continuously for 12 weeks after modeling. The blood glucose of rats was detected before intervention and at 4， 8， 12 weeks after intervention. At the 12th week， motor nerve conduction velocity （MNCV）， sensory nerve conduction velocity （SNCV）， nerve blood flow velocity， mechanical pain threshold， and thermal pain threshold were detected. The sciatic nerve was taken for hematoxylin-eosin （HE） staining to observe the tissue morphology. The ultrastructure of the sciatic nerve was observed by transmission electron microscope. The expression levels of superoxide dismutase （SOD）， malondialdehyde （MDA）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in sciatic nerve were determined by enzyme-related immunosorbent assay （ELISA）. The mRNA expressions of AMPKα， AMPKβ， PGC-1α， and SIRT3 in sciatic nerve were determined by real-time polymerase chain reaction （Real-time PCR）. ResultCompared with the normal group， fasting blood glucose in the model group was increased at each time point （P<0.01）. The mechanical pain threshold was decreased （P<0.05）， and the incubation time of the hot plate was extended （P<0.01）. MNCV， SNCV， and nerve blood flow velocity decreased （P<0.05）. The expression level of SOD was decreased （P<0.01）. The expression levels of MDA， IL-1β， and TNF-α were increased （P<0.01）. The mRNA expression levels of AMPKα， AMPKβ， PGC-1α， and SIRT3 were decreased （P<0.01）. The structure of sciatic nerve fibers in the model group was loose， and the arrangement was disordered. The demyelination change was obvious. Compared with the model group， the fasting blood glucose of rats in the high dose Tangbikang granule group was decreased after the intervention of eight weeks and 12 weeks （P<0.01）. The mechanical pain threshold increased （P<0.05）. The incubation time of the hot plate was shortened （P<0.01）. MNCV， SNCV， and Flux increased （P<0.05）. The expression level of SOD was increased （P<0.01）. The expression levels of MDA， IL-1β， and TNF-α were decreased （P<0.01）. The mRNA expression levels of AMPKα， AMPKβ， PGC-1α， and SIRT3 were increased （P<0.01）. The sciatic nerve fibers in the high-dose Tangbikang granule group were tighter and more neatly arranged， with only a few demyelinating changes. The high， medium， and low dose Tangbikang granule groups showed a significant dose-effect trend. ConclusionTangbikang granules may improve sciatic nerve function in diabetic rats by regulating AMPK/PGC-1α/SIRT3 signaling pathway partly to inhibit oxidative stress.

Altered Chief Cell Morphology in the Gastric Gland of Streptozotocin-Diabetic Rats

SUMMARY: Diabetes mellitus (DM) is a metabolic disorder with rising incidences worldwide. Gastric symptoms of DM have been reported, including nausea, vomiting, bloating, and epigastric pain. Moreover, acute to chronic gastritis and atrophic gastritis occur in DM can affect the chief cells of the gastric gland. Chief cells are vital because of their ability to digest and separate vitamin B12 from protein. Lack of vitamin B12 leads to impaired DNA synthesis and abnormal metabolism in red blood cells, and eventually leading to pernicious anemia. Furthermore, decreased vibratory and positional senses, numbness, ataxia with subacute combined degeneration, and dementia are present in pernicious anemic patients. Twenty-four male adult Sprague-Dawley rats were used in this study. The rats were divided into control (n = 12) and diabetic (n = 12) groups. The rats were further separated into two categories: short-term (4 weeks) and long-term (24 weeks) groups. DM model was induced by manually injecting intraperitoneally with streptozotocin in citrate buffer at a dose of 60 mg/kg body weight. The same amount of buffer was injected into the control group. After sacrifice, three regions of the stomach (the cardia, body, and pylorus) were dissected. Histopathology was performed by staining with toluidine blue. Image analysis was used to quantify the zymogen granule accumulation in chief cells. The data were compared between the control and DM rats in each period using Student's t-test. In addition, transmission electron microscopy (TEM) was also used to examine the ultrastructures. There was a significant decrease in the percentage of zymogen granules in DM rats. Under TEM, the destructions of mitochondria, rough endoplasmic reticulum, and Golgi apparatus in the DM rat were observed in the chief cells. In rats with uncontrolled diabetes, there is damage to the chief cells all over the area of the stomach, affecting digestion and malabsorption of vitamin B12. Therefore, this result helps clinicians recognize that diabetic patients with gastric symptoms may have hidden pernicious anemia.

La diabetes mellitus (DM) es un trastorno metabólico con incidencia creciente a nivel mundial. Se han informado síntomas gástricos de DM, que incluyen náuseas, vómitos, distensión abdominal y dolor epigástrico. Además, la gastritis aguda a crónica y la gastritis atrófica que ocurren en la DM pueden afectar las células principales de la glándula gástrica. Las células principales son vitales debido a su capacidad para digerir y separar la vitamina B12 de las proteínas. La falta de vitamina B12 conduce a una síntesis de ADN deteriorada y un metabolismo anormal en los glóbulos rojos, lo que eventualmente conduce a una anemia perniciosa. Además, los pacientes con anemia perniciosa presentan disminución de los sentidos vibratorio y posicional, entumecimiento, ataxia con degeneración combinada subaguda y demencia. En este estudio se usaron 24 ratas Sprague-Dawley macho adultas. Las ratas se dividieron en grupos control (n = 12) y diabéticas (n = 12). Las ratas se separaron además en dos categorías: grupos a corto plazo (4 semanas) y a largo plazo (24 semanas). El modelo de DM se indujo inyectando manualmente por vía intraperitoneal estreptozotocina en tampón de citrato a una dosis de 60 mg/kg de peso corporal. Se inyectó la misma cantidad de tampón en el grupo control. Después del sacrificio, se disecaron tres regiones del estómago (cardias, cuerpo y píloro). La histopatología se realizó mediante tinción con azul de toluidina. El análisis de imágenes se utilizó para cuantificar la acumulación de gránulos de zimógeno en las células principales. Los datos se compararon entre las ratas control y DM en cada período utilizando la prueba t de Student. Además, se utilizó microscopía electrónica de transmisión (TEM) para examinar la ultraestructura celular. Hubo una disminución significativa en el porcentaje de gránulos de zimógeno en ratas DM. Bajo TEM, se observaron en las células principales las destrucción de las mitocondrias, del retículo endoplásmico rugoso y del complejo golgiense en la rata DM. En ratas con diabetes no controlada, hay daño en las células principales de toda el área del estómago, lo que afecta la digestión y la malabsorción de vitamina B12. Por lo tanto, este resultado ayuda a los médicos a reconocer que los pacientes diabéticos con síntomas gástricos pueden tener una anemia perniciosa oculta.

Sustancia Cromatofílica: Una Propuesta de Cambio a la Terminologia Histologica y Terminologia Neuroanatomica / Chromatophilic Substance: a Proposal to Change the Terminologia Histologica and Terminologia Neuroanatomica

En Terminologia Histologica y Terminologia Neuroanatomica está registrado el término Substantia chromatophilica de origen grecolatino, con los códigos H2.00.06.1.00009 y 78, respectivamente. Dicho término ha sido empleado para referirse a un conglomerado de estructuras que en unión fungen como maquinaria de síntesis proteica y que son característicos de las células nerviosas. Teniendo en cuenta los lineamientos de la Federative International Programme for Anatomical Terminology (FIPAT) referentes a la denominación de nombres estructurales con un valor descriptivo e informativo, creemos que el término en cuestión no es el más adecuado. Por lo anterior, el objetivo del presente estudio fue analizar y evaluar la concordancia de las raíces grecolatinas que componen el término. Para ello, se llevó a cabo una búsqueda en el Diccionario de la lengua española, Diccionario de Términos Médicos, diccionario VOX Griego-Español y el diccionario VOX Ilustrado Latino-Español Español-Latino. Los resultados obtenidos indican que la palabra chromatophilica no presenta registro en español, sin embargo, sus sinónimos hacen referencia a material biológico afín por los colorantes. En base a lo anterior, proponemos el término Ribocumulus corponeuralis en función de su estructura y ubicación, en reemplazo de Substantia chromatophilica.

SUMMARY: In Terminologia Histologica and Terminologia Neuroanatomica the term Substantia chromatophilica of Greco-Latin origin is registered with the codes H2.00.06.1.00009 and 78, respectively. This term has been used to refer to a conglomerate of structures that together function as protein synthesis machinery and are characteristic of nerve cells. Considering the guidelines of the Federative International Programme for Anatomical Terminology (FIPAT) regarding the denomination of structural names with a descriptive and informative value, we believe that the term in question is not the most appropriate. Therefore, this study aimed to analyze and evaluate the concordance of the Greco-Latin roots that compose the term. For this purpose, a search was conducted in the Diccionario de la Lengua Española, Diccionario de Términos Médicos, Diccionario VOX Griego-Español and the Diccionario VOX Ilustrado Latino-Español Español-Latino. The results obtained indicate that the word chromatophilica is not registered in Spanish, however, its synonyms refer to biological material related to dyes. Based on the aforementioned, we propose the term Ribocumulus corponeuralis based on its structure and location, as a replacement for Substantia chromatophilica.

Efficacy of Yupingfeng granule combined with cetirizine in the treatment of allergic rhinitis and its effects on serum inflammatory factor level / 中国基层医药

Objective:To investigate the efficacy of Yupingfeng granule combined with cetirizine in the treatment of allergic rhinitis and its effects on serum inflammatory factor level. Methods:A total of 162 patients with allergic rhinitis admitted to Zhejiang Provincial Hospital of Chinese Medicine from January 2021 to March 2022 were included in this prospective controlled study. They were randomly divided into a control group and an observation group ( n = 81/group). The control group was treated with cetirizine and the observation group was treated with Yupingfeng granule combined with cetirizine. All patients were treated for 4 weeks. Clinical efficacy was compared between the two groups after 4 weeks of treatment. Main symptom score, nasal function indexes (total nasal airway resistance, nasal minimal cross-sectional area, and 0-5 cm nasal cavity volume), levels of inflammatory factors (interleukin-4, interleukin-6, and interleukin-10), and Rhinoconjunctivitis Quality of Life Questionnaire scores were compared between the two groups before and after 4 weeks of treatment. Results:Total response rate in the observation group was significantly higher than that in the control group [92.59% (75/81) vs. 79.01% (64/81), χ2 = 6.13, P < 0.05]. After 4 weeks of treatment, the scores of nasal congestion, nasal itching, and sneezing in the observation group were (0.63 ± 0.20) points, (0.70 ± 0.21) points, and (0.54 ± 0.17) points, which were significantly lower than (1.07 ± 0.23) points, (1.08 ± 0.24) points, and (0.89 ± 0.22) points in the control group ( t = 12.99, 10.72, 11.33, all P < 0.05). After 4 weeks of treatment, total nasal airway resistance in the observation group was significantly lower than that in the control group [(0.17 ± 0.05) kPa·s -1·L -1vs. (0.26 ± 0.06) kPa·s -1·L -1, t = 10.37, P < 0.05]. Nasal minimal cross-sectional area and 0-5 cm nasal cavity volume in the observation group were (0.94 ± 0.17) cm 2 and (9.74 ± 0.89) cm 3, respectively, which were significantly higher than (0.76 ± 0.10) cm 2 and (8.43 ± 0.78) cm 3 in the control group ( t = 8.21, 9.96, both P < 0.05). After 4 weeks of treatment, serum levels of interleukin-4 and interleukin-6 in the observation group were (67.79 ± 9.94) ng/L and (6.74 ± 1.42) ng/L, respectively, which were significantly lower than (104.31 ± 14.45) ng/L and (10.29 ± 2.56) ng/L in the control group ( t = 18.74, 10.91, both P < 0.05). Serum level of interleukin-10 in the observation group was significantly higher than that in the control group [(17.97 ± 2.54) ng/L vs. (12.48 ± 2.46) ng/L, t = 13.97, P < 0.05]. After 4 weeks of treatment, Rhinoconjunctivitis Quality of Life Questionnaire score in the observation group was significantly lower than that in the control group [(27.43 ± 8.82) points vs. (38.95 ± 7.76) points, t = 8.82, P < 0.05). Conclusion:Yupingfeng granule combined with cetirizine is highly effective on allergic rhinitis. The combined therapy can reduce clinical symptoms and inflammatory reactions, improve nasal function, and thereby improve quality of life.

Effect of Compound Duzhong Jiangu Granules on joint function, quality of life and inflammatory factors in patients with Kashin-Beck disease / 中华地方病学杂志

Objective:To study the effect of Compound Duzhong Jiangu Granules on joint function, quality of life and inflammatory factors in patients with Kashin-Beck disease.Methods:By group design, 135 patients with Kashin-Beck disease in Chongxin County, Pingliang City, Gansu Province, were selected and divided into intervention group (100 cases treated with Compound Duzhong Jiangu Granules, 12 g/bag, 1 bag/time, 3 times/day, treatment for 1 month) and control group (35 cases treated with ibuprofen, 0.3 g/capsule, 1 capsule/time, 2 times/day, treatment for 2 weeks) according to the randomized, single-blind principle. The changes of joint dysfunction index score, joint function improvement rate, total scores of Kashin-Beck disease quality of life (KBDQOL) and scores of each dimension were analyzed before treatment, 1 month and 3 months after treatment. The serum levels of interleukin-6 (IL-6), nuclear factor κB (NFκB)-p65, inducible nitric oxide synthase (NOS2), nitric oxide (NO), and prostaglandin E2 (PGE2) were detected by enzyme-linked immunosorbent assay before treatment and 1 month after treatment.Results:The total scores of joint dysfunction index of the intervention group and the control group 1 month after treatment and 3 months after treatment were lower than those before treatment, but 3 months after treatment was higher than 1 month after treatment ( P < 0.001). One month after treatment, the total effective rates of joint function improvement in the intervention group and the control group were 68.00% (68/100) and 54.55% (18/33), respectively; 3 months after treatment, the total effective rates of the intervention group and the control group were 36.00% (36/100) and 39.39%(13/33), respectively. The total scores and scores of each dimension of KBDQOL were not significant for the main effect of the group ( P > 0.05), but significant for the main effect at the time point ( P < 0.05), and there was no interactive effect ( P > 0.05). There were significant differences in the scores of social support and mental status dimensions in the intervention group at different time points ( P < 0.001). And in the intervention group, the total score, the scores of physical function, activity limitation, economy and overall health dimensions were statistically significant between before treatment and 1 month after treatment, 1 month after treatment and 3 months after treatment( P < 0.05); however, there was no significant difference between before treatment and 3 months after treatment ( P > 0.05). One month after treatment, the serum PGE2 levels of both groups were decreased ( P < 0.05), and there was no difference in other inflammatory factors at different groups and time points ( P > 0.05). Conclusion:Compound Duzhong Jiangu Granules can effectively inhibit the inflammatory reaction of patients with Kashin-Beck disease, promote the improvement of joint function and improve the quality of life in various aspects.

The role of Huaiqihuang Granules in the long-term management of bronchial asthma in young children: a multicenter real-world study / 中华实用儿科临床杂志

Objective:To observe the role of Huaiqihuang Granules (HQ) in the long-term management of bronchial asthma in young children, and the effective effect on concomitant rhinitis.Methods:A prospective real-world multicenter study was conducted in children aged 2-5 years with asthma diagnosed in the outpatient department (from April 2016 to March 2019)who received either inhaled corticosteroid (ICS)/leukotriene receptor antagonist (LTRA)(control group); inhaled ICS/LTRA plus HQ(combination group), or HQ alone(HQ group). All patients were followed up at week 4, 8, 12 after treatment. The number of days with asthma symptoms, the frequency of severe asthma attacks, the level of asthma control, and the days with rhinitis symptoms in the last 4 weeks were recorded. Differences before and after treatment, and those among groups after treatment were compared using Kruskal- Wallis H test or Wilcoxon rank-sum test. Results:A total of 2 234 eligible patients were recruited, and 2 147 cases completed followed-up visits, including 477, 1 374 and 296 cases in the control group, combination group, and HQ group, respectively. After the treatment, all 3 groups showed significant declines in the days with asthma symptoms, frequency of severe asthma attack and the days with rhinitis symptoms (all P<0.01), and the rate of well-controlled asthma increased significantly ( P<0.01). It lasted until the end of follow-up. Among groups, patients in the combination group showed significantly less days of asthma symptoms than those of the other 2 group at week 8 and 12[0(0, 0.9) d vs.0(0, 0.3) d, P<0.05; 0(0, 0.1) d vs. 0(0, 1.0) d, P<0.01]. Patients in the combination group and HQ group showed a significantly lower rate of severe asthma attacks than that of the control group at week 12 [0(0, 1), 0(0, 1), 0(0, 2), all P<0.05]. The well-controlled rate of asthma in the combination group was significantly higher than that of the control group and HQ group at week 8 and 12 (89.6% vs. 85.9% vs.82.1%, H=15.28; 90.9% vs. 84.1% vs. 81.8%, χ2=29.32, all P<0.01). Conclusions:HQ can significantly alleviate symptoms of asthma and rhinitis, severe attack of asthma, and increase the control rate of asthma when used as an additional treatment or used alone.

Study on the mechanism of Kangmin Zhisou Granules in the treatment of bronchial asthma based on network pharmacology and animal experiments / 国际中医中药杂志

Objective:To deeply explore the potential mechanism of Kangmin Zhisou Granules in the treatment of bronchial asthma through network pharmacology method; To verify it with animal experiments.Methods:The active components and corresponding target information of Kangmin Zhisou Granules were screened with the help of BATMAN-TCM database, and the related disease targets of bronchial asthma were obtained through GeneCards and OMIM databases. The drug targets and bronchial asthma targets were intersected and imported String database was used to establish PPI network. Cytoscape 3.9.1 software was used to draw the network diagram of "Chinese materia medica-active components-intersection targets" and the core targets were screened. GO and KEGG enrichment analysis was performed on the core targets using DAVID database. A mouse model of asthma induced by ovalbumin was prepared. After the intervention of Kangmin Zhisou Granules, the pathological changes of mouse lung tissue were observed, and the contents of serum TNF-α, IL-6, IL-1 β were detected by ELISA.Results:Totally 240 active components and 1 364 potential targets were obtained from Kangmin Zhisou Granules. Tumor necrosis factor (TNF), interleukin-6 (IL-6), protein kinase B (AKT1), albumin (ALB), interleukin 1-beta (IL-1β) and other 11 core targets were obtained after screening. The results of GO enrichment analysis showed that the treatment of bronchial asthma by Kangmin Zhisou Granules mainly involved the positive regulation of protein phosphorylation, the regulation of inflammatory response, lipopolysaccharide response and other biological processes, as well as TNF, activated protein kinase (MAPK), interleukin-17 (IL-17) and other signaling pathways. Animal experiments confirmed that Kangmin Zhisou Granules could reduce the expression levels of TNF-α, IL-6 and IL-1β in serum ( P<0.05), and reduce the infiltration of inflammatory cells in the lung tissue of mice, thereby relieving asthma symptoms. Conclusion:Kangmin Zhisou Granules may exert anti-inflammatory effects by acting on TNF-α, IL-6, IL-1β and other targets to alleviate asthma symptoms.
