ABSTRACT

Purpose: To determine the effect of gallic acid or its combination with glibenclamide on some biochemical markers and histology of the cornea of streptozotocin (STZ) induced diabetic rats. Methods: Following induction of diabetes, 24 male albino rats were divided into four groups of six rats each. Groups 1 and 2 (control and diabetic) received rat pellets and distilled water; group 3 (gallic acid) received rat pellets and gallic acid (10 mg/kg, orally) dissolved in the distilled water; and group 4 (gallic acid + glibenclamide) received rat pellets, gallic acid (10 mg/kg, orally), and glibenclamide (5 mg/kg, orally) dissolved in the distilled water. The treatments were administered for three months after which the rats were sacrificed after an overnight fast. Blood and sera were collected for the determination of biochemical parameters, while their eyes were excised for histology. Results: STZ administration to the rats induced insulin resistance, hyperglycemia, microprotenuria, loss of weight, oxidative stress, inflammation, and alteration of their cornea histology, which was abolished following supplementation with gallic acid or its combination with glibenclamide. Conclusions: The study showed the potentials of gallic acid and glibenclamide in mitigating systemic complication and histological changes in the cornea of diabetic rats induced with STZ.

ABSTRACT

Objective@#To investigate the incidence of abnormal spinal curvature and related factors among middle school students in the Inner Mongolia Autonomous Region, so as to provide evidence for abnormal spinal curvature prevention and treatment.@*Methods@#By using a random stratified cluster sampling method, 87 908 students of middle and high school students from all 12 counties(districts) were investigated via questionnaires for abnormal spinal curvature and health influencing factors in Inner Mongolia Autonomous Region. Chi square test was used to perform demographic characteristics and univariate analysis, and binary multivariate Logistic regression model was used to screen the risk factors for spinal curvature abnormalities in middle school students.@*Results@#A total of 3 131(3.56%) students with spinal curvature abnormalities were detected, with boys (3.69%) higher than that of girls(3.44%), urban areas (6.15%) higher than that of the suburban counties (2.50%), and high school students ( 4.97 %) higher than that of junior high school(2.73%) students( χ 2=4.01, 702.19, 299.36, P <0.05). The detectable rate of spinal curvature abnormalities increased with grade ( χ 2 trend =309.29, P <0.05). Logistic regression analysis showed that factors influencing abnormal spinal curvature included myopia, overweight, obesity, the frequency of classroom seating arrangements, time spent on homework/reading after school every day, time spent in daytime outdoor activities, self imposed requirements for posture of sitting and standing, phase of studying, gender, and area ( OR =0.53-2.55, P <0.05).@*Conclusion@#Abnormal spinal curvature is strongly correlated to nutritional status, myopia, sitting posture when reading and writing, sedentary time, and time spent in outdoor activities. The collaboration of multiple departments is required to establish anenvironment to protect the spine, early detection and early intervention.

ABSTRACT

Objective@#To understand the current situation and influencing factors of scoliosis in 12-year-old students from Inner Mongolia Autonomous Region, so as to provide scientific basis for accurate prevention and control of abnormal spinal curvature.@*Methods@#From October to November 2021, a total of 18 399 students aged 12 were selected by region and school level by stratified random cluster sampling method, and spinal curvature screening and questionnaire survey of common diseases and health influencing factors among students were carried out. Chi squared test was used for single factor analysis, and binary Logistic regression model was used for multi factor analysis.@*Results@#A total of 397 students (2.2%) were detected with abnormal curvature of the spine, including 368 students (2.0%) with scoliosis. Among them, 205 cases were in the lumbar thoracic segment with a detection rate of 1.1%, 173 cases were in the thoracic segment with a detection rate of 0.9%, and 141 cases were in lumbar thoracic segment with a detection rate of 0.8%. Binary Logistic regression analysis showed that urban area, economic area(moderate), attending tutorial classes before primary school and class seats never changed regularly were positively correlated with the occurrence of scoliosis among 12 year old students ( OR =1.95,1.67,1.76,1.71, P <0.05). Obesity, attending an average of 3 or 4 physical education classes per week, attending physical fitness and beauty classes before primary school were negatively correlated with the occurrence of scoliosis among 12 year old students ( OR =0.69,0.31,0.36,0.71, P <0.05).@*Conclusion@#The prevalence of scoliosis among 12-year-old students in Inner Mongolia Autonomous Region is not optimistic. It should pay attention to the prevention and control of scoliosis in students before the age of 12, actively prevent the occurrence and progress of scoliosis.

ABSTRACT

@#Objective To explore the transitive regularity of holistic constituents from the crude slices of the medicinal raw materials (MCS) to the formula granules (FG), fufang decoction (FD), and finally, the concentrated pills (CP) of Liuwei Dihuang Fufang (六味地黄复方, LWDHF). Methods Samples for MCS, FG, FD, and CP of LWDHF were obtained, and a fingerprint database was established using high-performance liquid chromatography (HPLC), by separating the samples in an XB-C18 column and analyzing the transitive regularity of components using the total quantum statistical moment (TQSM), including total quantum zero moment (AUCT), total quantum first moment (MRTT), total quantum second moment (VRTT), and its similarity approach. The AUCT, MRTT, and VRTT were calculated based on the representative HPLC chromatograms of FG, FD, and CP of LWDHF. Results AUCT of FG, FD, and CP of LWDHF was 71 804, 46 553, and 144 646 µV·s, respectively; MRTT was 14.43, 14.54, and 18.85 min, respectively; and VRTT was 106.98, 112.84, and 269.12 min2, respectively. Comparing the similarity of FG/FD, FG/CP and FD/CP of LWDHF, the TQSM similarity values were 98.66%, 76.62%, and 75.37%, respectively, whereas the traditional similarity evaluation values were 98.68%, 85.43%, and 85.60%, respectively. Conclusion The results perform little distinction in the total composition between FG and FD, whereas some distinction existed between FD and CP. Experimental evidence, therefore indicates that FG could be used as the alternative of MCS in clinical applications.

ABSTRACT

SUMMARY: The Saanen goat is known as the greatest milk producer among small ruminat breeds. However, its morphometric features still remain unclear. Therefore, the present work aimed to investigate the functional anatomy of the upper and lower jaws as well as the volumetric properties of the male and female Saanen goat for clinical applications. The heads of 20 adult animals (10 males and 10 females) were included. Totally, 22 morphometric parameters were measured on three dimensional computed tomographic images using RadiAnt DICOM Viewer software and some parameters were measured on hot macerated sample. The mean volume of paranasal sinuses as well as conchal sinuses were estimated using stereological method. Based on the results, the differences between males and females were not significant (p>0.05) in all desired parameters.The frontal and lacrimal sinuses were the largest and smallest paranasal sinus in both sexes. Also, the dorsal and middle conchal sinuses were the largest and smallest ones, respectively. The common nasal meatus was the smallest and ventral meatus was the largest meatus in the nasal cavity. In conclusion, these findings provide a basic data that would be useful in blocking terminal branches of the cranial nerves in this breed for surgical purpose or teeth injuries treatment.


RESUMEN: La cabra Saanen es conocida como la mayor productora de leche entre las razas de pequeños ruminos, sin embargo, sus características morfométricas aún permanecen sin revelar. Por lo tanto, el presente trabajo tuvo como objetivo investigar la anatomía de los huesos del cráneo y cara, así como sus propiedades volumétricas, en la cabra Saanen, tanto del macho como de la hembra con la finalidad de contribuir con las aplicaciones clínicas. Se incluyeron las cabezas de 20 animales adultos (10 machos y 10 hembras). Se midieron 22 parámetros morfométricos en imágenes de tomografía computarizada tridimensionales utilizando el software RadiAnt DICOM Viewer; algunos parámetros se midieron en muestra macerada en calor. El volumen medio de los senos paranasales y concales se estimó mediante método estereológico. En base a los resultados, las diferencias entre machos y hembras no fueron significativas (p> 0.05) en todos los parámetros deseados. Los senos frontal y lagrimal eran de mayor y menor volumen en ambos sexos, respectivamente. Además, los senos conchal dorsal y medio eran los más grandes y los más pequeños, respectivamente. El meato nasal común fue el más pequeño y el meato ventral el más grande en la cavidad nasal. En conclusión, estos hallazgos brindan un dato básico que sería útil en el bloqueo de las ramas terminales de los nervios craneales en esta raza, con fines quirúrgicos o tratamiento de lesiones dentales.

ABSTRACT

Due to the extensive use of xylooligosaccharides (XOS) as functional food ingredients,many inferior goods and even adulterants are generally found in the market,which may pose a health hazard to certain populations.Chromatography method such as high-performance liquid chromatography (HPLC) and high-performance thin-layer chromatography (HPTLC) is traditionally applied for the quality analysis of XOS.However,it is time consuming due to the prolonged separation and pre-or post-derivatization procedure.In this study,a fast saccharide mapping method based on matrix-assisted laser desorption/time-of-flight mass spectrometry (MALDI-TOF-MS) was developed for the quality consistency analysis of 22 batches of XOS collected from different manufacturers in China.The time needed for saccharides analysis using MALDI-MS was less than 30 min for one plate,at least 6 times faster than that by the traditional HPTLC chromatography method.In addition,MALDI-MS possessed higher resolution for XOS with DP4-DP7 based on the difference of m/z,which is hardly separated using HPTLC.The results showed that XOS were present only in samples XY01-XY11,samples XY12-XY14 only consisted of hex oligo-saccharides,and samples XY15-XY22 were free of oligosaccharides.These indicate that the quality consistency of XOS products in the China market was poor,which should be carefully investigated.

ABSTRACT

Objective:To explore the distribution characteristics of traditional Chinese medicine (TCM) syndromes of abnormal uterine bleeding associated with ovulatory dysfunction (AUB-O). Method:A clinical and epidemiological investigation was conducted in 6 688 patients with AUB-O from the provincial, municipal, and county/district hospitals in 29 provinces, autonomous regions, and municipalities across China to identify the distribution characteristics of their TCM syndromes. Result:The AUB-O patients nationwide were mainly differentiated into the kidney Qi deficiency syndrome (17.34%), the spleen Qi deficiency syndrome (13.25%), the Qi and blood deficiency syndrome (12.62%), the Qi deficiency and blood stasis syndrome (8.45%), and the kidney Yin deficiency syndrome (6.88%). AUB-O resulted from Qi deficiency, Yin deficiency, and blood deficiency, often involving the kidney, spleen and liver. The analysis of the regional distribution of TCM syndromes in AUB-O patients revealed that kidney Qi deficiency, spleen Qi deficiency, and Qi and blood deficiency were the shared syndromes. However, due to regional discrepancy, the TCM syndrome varied widely from one geographic region to another. The kidney Qi deficiency syndrome was more frequently seen in North China, Northwest China, Southwest China, and East China, but less frequently in central China, Northeast China, and South China. The spleen Qi deficiency syndrome occurred most frequently in central China, while the East China had the highest frequency of Qi and blood deficiency syndrome. The spleen and kidney deficiency syndrome was mostly present in central China, North China, and Southwest China, the Qi deficiency (kidney deficiency) and blood stasis syndrome in Northwest China, South China, and North China, the kidney Yin deficiency syndrome in East China, Northwest China, and Northeast China, the deficiency-heat syndrome in Southwest China and East China, the kidney Yang deficiency syndrome in South China, the liver depression and blood heat syndrome in Northeast China, and the liver depression and spleen deficiency syndrome in central China. The diagnostic criteria for the kidney Qi deficiency, spleen Qi deficiency, Qi and blood deficiency, Qi deficiency and blood stasis, and kidney Yin deficiency syndromes were not significantly different from the previous ones. The distinctive symptoms for the kidney Qi deficiency syndrome were irregular vaginal bleeding, heavy menstrual flow, or shortened menstrual cycle, back soreness and pain, and forgetfulness, while those for the spleen Qi deficiency syndrome mainly included the shortened menstrual cycle, mental fatigue, lack of strength, poor appetite, loose stool, and white tongue coating. The Qi and blood deficiency syndrome were mainly manifested as the shortness of breath, laziness to speak, pale complexion, dizziness, and palpitation. The Qi deficiency and blood stasis syndrome were mainly judged by the scanty menstrual flow frequently or occasionally accompanied by blood clots, mental fatigue, lack of strength, and dark purple tongue. The ovulatory bleeding, dizziness, tinnitus, vexing heat in chest, palms and soles, and night sweat were the characteristic signs for the kidney Yin deficiency syndrome. Conclusion:There exist certain rules in the geographical distribution of TCM syndromes of AUB-O patients, which has provided a reference for the clinical treatment of AUB-O in accordance with the local conditions.

ABSTRACT

Gestational diabetes mellitus(GDM)can cause blood glucose disorders in pregnant women and result in adverse maternal-neonatal outcomes.Vitamin D(VD)can improve glucose tolerance and insulin sensitivity,and thus theoretically,VD supplementation during pregnancy could improve glycemic control as well as maternal-neonatal outcomes in GDM patients.Although studies have shown that VD deficiency is associated with poor maternal-neonatal outcomes in GDM patients,no solid conclusion has been drawn with regard to the effects of VD supplementation on these patients.Therefore,here we summarized the research progress of the effects of VD supplementation on glycemic control and adverse maternal-neonatal outcomes in GDM patients,in an effort to guide the clinical VD supplementation during pregnancy.

ABSTRACT

Retroperitoneal leiomyosarcoma is relatively uncommon. Leiomyosarcoma has accounted for about 5%-10% of soft-tissue sarcoma, and 1/2–2/3 of the primary lesions were retroperitoneal, with a cumulative 5-year survival rate of only 35%.Leiomyosarcoma is one kind of soft-tissue sarcoma with the lowest survival rates due to the invasive growth, difficult treatment, and poor prognosis.The present study reported a case of a 78-year-old male diagnosed as left retroperitoneal leiomyosarcoma, who had received three operations. Computed tomography (CT) demonstrated a mass of approximately 12.9 cm × 6.9 cm × 6.6 cm in his retroperitoneal region. The Eastern cooperative oncology group and numerical rating scale scores of pain were 1 and 5, respectively. Multiple treatment strategies were administered, including the application of drainage and125I seed implantation. A total of 90125I seeds were implanted into the tumor through repetitious operations, with 30 seeds each time. Treatment planning system was involved to calculate the source distribution.125I seeds with the activity of 0.5 mCi were implanted under the guidance of CT, and dosimetric verification was performed after the operation. D90 (90% minimum prescription dose received by target volume) was 40 Gy. Follow-up was performed after 6 months, and complete response was achieved in the local lesions. However, there was no evidence-based treatment currently and the majority of our knowledge was based on results from case reports, thus further studies would be required

ABSTRACT

Lung cancer is the most common malignancy worldwide and is characterized by rapid progression, aggressive behavior, frequent recurrence, and poor prognosis. The TCGA database indicates that chondroitin polymerizing factor (CHPF) is overexpressed in human lung cancer tissues compared with normal tissues and this overexpression corresponds to shorter overall survival in lung cancer patients. In this study, to investigate the function of CHPF in lung cancer, lentiviral vectors expressing CHPF shRNA were stably transduced into A549 and H1299 cells. Compared to shCtrl cells, CHPF knockdown cells had significantly reduced proliferation. Furthermore, the silencing of CHPF in A549 and H1299 cells resulted in apoptotic induction, which led to decreased colony formation. Wound healing and transwell invasion assays revealed that CHPF could positively regulate the migration of lung cancer cells. The tumorigenic role of CHPF was also validated in nude mouse xenograft models. Affymetrix gene chip analysis indicated that CHPF regulated the proliferation and invasion of lung cancer cells through CDH1, RRM2, MKI67, and TNFRSF10B. We thus highlight CHPF as a novel target for lung cancer treatment.

ABSTRACT

OBJECTIVE: To isolate four polysaccharides from Tremella and study their physicochemical properties, microstructures, antioxidant activities and anti-inflammation effects. METHODS: The polysaccharides were purified using water extraction method, DEAE-Sepharose CL-6B and Sephadex G-100. The physicochemical properties and microstructures were studied using high-performance size-exclusion chromatography (HPSEC), gas chromatography (GC), Fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM) analysis. Anti-inflammation activities of the polysaccharides were identified using real time quantitative PCR. RESULTS: Four kinds of major polysaccharides (TABW-Ⅱ, TFBW-Ⅱ, TEPW-Ⅱ and TSPW-) were purified from water-extraction crude polysaccharides from Tremella. TABW-Ⅱ, TFBW-Ⅱ, TEPW-Ⅱ and TSPW- were homogeneous with relative molecular mass 26×103, 11×103, 21×103 and 356×103, respectively, and they consisted mainly of glucose and mannose. TEM reveale that their molecular morphologies were linear, and TSPW- had more extended structure with entangled chains. Compared with vitamin C (Vc), TSPW- showed more noticeable scavenging effects of superoxide (EC50=0.127 mg•mL-1) and hydroxyl (EC50=0.088 mg•mL-1) radicals (P<0.05). TSPW- also showed the highest inhibitory effects of TNF-α, IL-6 and COX-2 mRNA expressions in LPS-stimulated RAW 264.7 mouse macrophage cells, and the inhibitory effects were more than 95% at 150 μg•mL-1 TSPW-. CONCLUSION: The results indicate that TSPW- with entangled and extended liner structures have more obvious antioxidant and anti-inflammation effects than other major polysaccharides from Tremella family. Furthermore, this study indicates the potential utilization of Tremella polysaccharides in anti-inflammatory agents.

ABSTRACT

Objective:To investigate the application value of superb microvascular imaging (SMI) in benign and malignant renal lesions by comparing with power Doppler imaging (PDI). Methods:Retrospective analysis was performed on 48 cases of renal lesions in 47 pa-tients screened via PDI and SMI at Tianjin Medical University Cancer Institute and Hospital. A total of 10 and 38 cases of benign and malignant lesions were identified, respectively. We compared the diagnostic efficiency between the two methods by determining blood flow grade, distribution pattern, morphology, and ring-like blood flow. Results:Statistically significant differences in ring-like blood flow (P<0.05) but not in blood flow grade, distribution pattern, and morphology (P>0.05) were observed between benign and malignant renal tumors as detected by PDI. In SMI, statistically significant differences in blood flow grade, distribution pattern, mor-phology, and ring-like blood flow were identified between benign and malignant renal tumors (P<0.05). The sensitivity, specificity, and area under the receiver operating characteristic curve of PDI and SMI were 71.05%, 70.00%, and 0.705 and 89.47%, 90.00%, and 0.897, respectively. Significance in diagnostic efficacy between PDI and SMI was detected (P=0.025). Conclusion:Compared with PDI, SMI can more accurately describe blood flow grade, distribution pattern, morphology, and ring-like blood. Thus, SMI can improve the accuracy of differential diagnosis of benign and malignant renal tumors.

ABSTRACT

Objective:To investigate the function of breast cancer susceptibility gene variants in predicting breast cancer risk and guid-ing clinical treatment through DNA sequencing. Methods:This study involved 146 patients, 71 high-risk cases, and 55 healthy people, totaling 272 cases. The subjects were treated in Tianjin Medical University Cancer Institute and Hospital from November 2013 to July 2015. Genomic DNA was sequenced by a second generation sequencing platform. All exon areas of six common breast cancer suscepti-bility genes (BRCA1, BRCA2, PTEN, STK11, TP53, and RAP1) were sequenced through amplicon sequencing method. Meaningful vari-ants including single nucleotide variants (SNVs), insertion-deletions (InDels) and nonsense mutations were selected and statistical methods, such as t test andχ2 test, were used to analyze the statistical differences in incidence rates among three groups. Results:A total of 177 meaningful variants were confirmed, including 50 SNVs, 8 nonsense mutations, and 9 InDels. Among the variants, 31 were recorded in the Exome Aggregation Consortium (ExAC), 40 were noted in ClinVar database, and 21 were not encoded in the present da-tabase, which were defined as new variants in this study. Conversely, 57 variants (85.1%) were found in breast cancer patients and high-risk cases, and the incidence of axillary lymph node metastasis (P=0.010) and pathological stages (P=0.002) in mutation positive patients were both higher than mutation negative patients. Moreover, the percentage of family history of cancer (P=0.005) and triple negative breast cancer (P=0.009) were both higher in patients carrying pathogenic mutations than in nonpathogenic patients. Conclu-sion:Breast cancer susceptibility gene variants may not only be a tool used to predict the risk of getting breast cancer but also a mean-ingful guideline for the clinical treatment and prognosis evaluation.
