ABSTRACT

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disease worldwide. Current guidelines of IBS are mostly based on the western populations and expected to vary in different communities. China has a large population and a vast literature is available on IBS. Due to linguistic variations in the literature, the studies are not widely known and their conclusions thus remain largely obscured to the western medical literature. In this article, we reviewed the published literatures on the investigations of IBS epidemiology, diagnosis, and management in the Chinese population and emphasized the different findings gleaned from the western publications. The detailed literature review will benefit understanding of and promote future study on IBS.

ABSTRACT

BACKGROUND@#Colorectal cancer is harmful to the patient's life. The treatment of patients is determined by accurate preoperative staging. Magnetic resonance imaging (MRI) played an important role in the preoperative examination of patients with rectal cancer, and artificial intelligence (AI) in the learning of images made significant achievements in recent years. Introducing AI into MRI recognition, a stable platform for image recognition and judgment can be established in a short period. This study aimed to establish an automatic diagnostic platform for predicting preoperative T staging of rectal cancer through a deep neural network.@*METHODS@#A total of 183 rectal cancer patients' data were collected retrospectively as research objects. Faster region-based convolutional neural networks (Faster R-CNN) were used to build the platform. And the platform was evaluated according to the receiver operating characteristic (ROC) curve.@*RESULTS@#An automatic diagnosis platform for T staging of rectal cancer was established through the study of MRI. The areas under the ROC curve (AUC) were 0.99 in the horizontal plane, 0.97 in the sagittal plane, and 0.98 in the coronal plane. In the horizontal plane, the AUC of T1 stage was 1, AUC of T2 stage was 1, AUC of T3 stage was 1, AUC of T4 stage was 1. In the coronal plane, AUC of T1 stage was 0.96, AUC of T2 stage was 0.97, AUC of T3 stage was 0.97, AUC of T4 stage was 0.97. In the sagittal plane, AUC of T1 stage was 0.95, AUC of T2 stage was 0.99, AUC of T3 stage was 0.96, and AUC of T4 stage was 1.00.@*CONCLUSION@#Faster R-CNN AI might be an effective and objective method to build the platform for predicting rectal cancer T-staging.@*TRIAL REGISTRATION@#chictr.org.cn: ChiCTR1900023575; http://www.chictr.org.cn/showproj.aspx?proj=39665.

ABSTRACT

Objective:To analyze risk factors for the rupture of basilar tip aneurysms (BTA) using morphological parameters assessed on CTA.Methods:The clinical data and CTA imaging characteristics of 62 patients with BTA from March 2016 to November 2020 in Huanhu Hospital of Tianjin were analyzed retrospectively. The patients were divided into un-rupture ( n=44) and rupture ( n=18) groups according to whether the BTA ruptured. The morphological parameters of aneurysms were measured and recorded. The number, shape and orientation of aneurysms were analyzed by χ 2 test between the two groups. The length (H max), height (H p), neck width (N D), aspect ratio (AR), size ratio (SR), angle of aneurysms (AA), flow angle (FA), basilar vessel angle (BVA), the angle between the proximal long axis of bilateral posterior cerebral artery P1 segment (P1-P1 angle), the angle between the proximal long axis of bilateral superior cerebellar arteries and bifurcation angle (the sum of the angle between the basilar artery and the bilateral posterior cerebral arteries) were analyzed by independent-sample t test between the two groups. On the basis of univariate analysis, logistic regression was used to identify the independent risk factors for BTA rupture. ROC curve analysis was further performed. Results:BTA with irregular shape was more likely to break (χ 2=5.412, P<0.05). The H max[(4.18±2.11)mm], N D [(3.06±1.75)mm], P1-P1 angle (148°±18°) in the rupture group were smaller than those in the un-rupture group [(6.38±2.21)mm, (5.20±1.59)mm, 178°±25°], with statistically significant difference ( P<0.05). While AR (1.19±0.13), BVA (82°±11°), and bifurcation angle (212°±18°) in the rupture group were larger than those in the un-rupture group (1.05±0.18, 70°±10°, 181°±27°), with statistically significant difference ( P<0.05). The logistic regression analysis showed that the shape of aneurysms (β=4.878, OR=11.418, P=0.019), BVA (β=0.165, OR=1.177, P=0.043), and P1-P1 angle (β=-0.223, OR=1.080, P=0.029) were independent risk factors for BTA rupture. The ROC curve analysis showed that the cut-off value of BVA and P1-P1 angle to predict the BTA rupture were 76.7° and 158.5°, and area under curve (AUC) were 0.79 and 0.86, respectively. The AUC of combined BVA with P1-P1 angle was 0.89. Conclusion:The shape of aneurysms, BVA and P1-P1 angle are independent risk factors for BTA rupture. BTA are prone to rupture when the shape of aneurysm is irregular, BVA>76.7 ° and P1-P1 angle<158.5 °.

ABSTRACT

In the past few years, continuous manufacturing(CM) has been put forward by the FDA. Pharmaceutical enterprises are encouraged to promote the implementation of CM, which has become a hot research direction of pharmaceutical technology. In February 2019, the FDA issued a draft guideline for the implementation of CM, which greatly promoted the development of CM and provided reference for continuous manufacturing of traditional Chinese medicine(TCM). The production process of TCM is a complex system. With the innovation of production equipment and the promotion of automation and informatization of TCM production, the exis-ting policies, regulations and traditional production control capacity are difficult to meet the market demand for high-quality TCM pro-ducts. In this paper, we reviewed the new technologies and methods of quality control in accordance with the characteristics of TCM production by referring to modern manufacturing technology, information technology and quality control technology. Based on the "QbD" theory and "PAT" technology, process knowledge system(PKS), an advanced control strategy, was proposed to provide a reference for the implementation of CM in TCM production.

ABSTRACT

Near-infrared spectroscopy(NIRS) combined with band screening method and modeling algorithm can be used to achieve the rapid and non-destructive detection of the traditional Chinese medicine(TCM) production process. This paper focused on the ginkgo leaf macroporous resin purification process, which is the key technology of Yinshen Tongluo Capsules, in order to achieve the rapid determination of quercetin, kaempferol and isorhamnetin in effluent. The abnormal spectrum was eliminated by Mahalanobis distance algorithm, and the data set was divided by the sample set partitioning method based on joint X-Y distances(SPXY). The key information bands were selected by synergy interval partial least squares(siPLS); based on that, competitive adaptive reweighted sampling(CARS), successive projections algorithm(SPA) and Monte Carlo uninformative variable(MC-UVE) were used to select wavelengths to obtain less but more critical variable data. With selected key variables as input, the quantitative analysis model was established by genetic algorithm joint extreme learning machine(GA-ELM) algorithm. The performance of the model was compared with that of partial least squares regression(PLSR). The results showed that the combination with siPLS-CARS-GA-ELM could achieve the optimal model performance with the minimum number of variables. The calibration set correlation coefficient R_c and the validation set correlation coefficient R_p of quercetin, kaempferol and isorhamnetin were all above 0.98. The root mean square error of calibration(RMSEC), the root mean square error of prediction(RMSEP) and the relative standard errors of prediction(RSEP) were 0.030 0, 0.029 2 and 8.88%, 0.041 4, 0.034 8 and 8.46%, 0.029 3, 0.027 1 and 10.10%, respectively. Compared with the PLSR me-thod, the performance of the GA-ELM model was greatly improved, which proved that NIRS combined with GA-ELM method has a great potential for rapid determination of effective components of TCM.

ABSTRACT

Fermentation engineering is an industrial process that uses the transformation of microorganisms or other cells to produce a specific product in a specific bioreactor. Fermentation engineering has developed from an ancient food fermentation relying solely on experience accumulation to an important production mode of food, agriculture, medicine, chemical industry and other means of production and life. It has become a key technology to support the sustainable development of human beings, and is inseparable from the continuous progress of interdisciplinary technology. The interdisciplinary integration and the continuous upward movement of China's global industrial chain will inevitably put forward higher requirements for the cultivation of fermentation engineering composite talents in the new situation. In order to constantly improve the interdisciplinary fermentation engineering compound talent training system, in recent years, the research lab has been refining and improving the concept of talent training, and actively deepening the reform of talent training system. Systematic research and practice have been carried out around the aspects of training program, enrollment system, teacher background, subject setting, scientific research practice, evaluation system, etc., which has promoted the technological progress of fermentation engineering and related supporting industries, and contributed an important force to the transformation of China from a big fermentation country to a powerful fermentation country.

ABSTRACT

Context: Owing to the increasing age of the population, the incidence of hepatocellular carcinoma (HCC) in the elderly is increasing annually. Aims: This study aims to investigate the clinical efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with low-dose apatinib for unresectable HCC treatment in elderly patients (≥65 years). Settings and Design: The clinical data from 61 elderly patients with unresectable HCC who were retrospectively analyzed. Subjects and Methods: Of these 61 patients, 27 received TACE combined with low-dose (250 mg/qd) apatinib (experimental group), and 34 patients received the standard TACE treatment (control group). The short-term efficacy was evaluated according to the mRECIST1.1 standards, and the mid- and long-term efficacy and safety in the two groups of patients were evaluated. Statistical Analysis Used: Statistical analyses were performed using the Statistical Package for the Social Sciences software (version 20.0; SPSS). Results: Both the objective response rate and disease control rate of the experimental group were significantly higher than those of control group (P < 0.05). The 6-month and 12-month survival rates of the experimental group were significantly higher than those of control group too (P < 0.05). The median survival in the experimental group was longer than in the control group (26.0 months vs. 20.0 months). The adverse reactions related to the intake of apatinib were higher in the experimental than the control group, but were generally alleviated after symptomatic treatment. Conclusions: TACE combined with low-dose apatinib provides an alternative treatment option for elderly patients with unresectable HCC. Our clinical study has proven its safety and efficacy.

ABSTRACT

BACKGROUND@#Texture analysis (TA) can quantify intra-tumor heterogeneity using standard medical images. The present study aimed to assess the application of positron emission tomography (PET) TA in the differential diagnosis of gastric cancer and gastric lymphoma.@*METHODS@#The pre-treatment PET images of 79 patients (45 gastric cancer, 34 gastric lymphoma) between January 2013 and February 2018 were retrospectively reviewed. Standard uptake values (SUVs), first-order texture features, and second-order texture features of the grey-level co-occurrence matrix (GLCM) were analyzed. The differences in features among different groups were analyzed by the two-way Mann-Whitney test, and receiver operating characteristic (ROC) analysis was used to estimate the diagnostic efficacy.@*RESULTS@#InertiaGLCM was significantly lower in gastric cancer than that in gastric lymphoma (4975.61 vs. 11,425.30, z = -3.238, P = 0.001), and it was found to be the most discriminating texture feature in differentiating gastric lymphoma and gastric cancer. The area under the curve (AUC) of inertiaGLCM was higher than the AUCs of SUVmax and SUVmean (0.714 vs. 0.649 and 0.666, respectively). SUVmax and SUVmean were significantly lower in low-grade gastric lymphoma than those in high grade gastric lymphoma (3.30 vs. 11.80, 2.40 vs. 7.50, z = -2.792 and -3.007, P = 0.005 and 0.003, respectively). SUVs and first-order grey-level intensity features were not significantly different between low-grade gastric lymphoma and gastric cancer. EntropyGLCM12 was significantly lower in low-grade gastric lymphoma than that in gastric cancer (6.95 vs. 9.14, z = -2.542, P = 0.011) and had an AUC of 0.770 in the ROC analysis of differentiating low-grade gastric lymphoma and gastric cancer.@*CONCLUSIONS@#InertiaGLCM and entropyGLCM were the most discriminating features in differentiating gastric lymphoma from gastric cancer and low-grade gastric lymphoma from gastric cancer, respectively. PET TA can improve the differential diagnosis of gastric neoplasms, especially in tumors with similar degrees of fluorodeoxyglucose uptake.

ABSTRACT

A high performance liquid chromatography charged aerosol detector (HPLC-CAD) method was established for the simultaneous determination of five saponins (notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, Ginsenoside Rd) in Yaobitong capsule, providing a method for quality control. The sample was extracted with methanol and chromatographic separation was performed on a Waters Xbridge Phenol column (150 mm×4.6 mm, 3.5 μm) using acetonitrile-water as the mobile phase with gradient elution at a flow rate of 1.0 mL·min-1. The column temperature was 30 ℃ and the injection volume was 10 μL. The nebulizer temperature of CAD was 35 ℃ and the air pressure was 60.2 psi, the filtration was 3.6 s, and the collection frequency was 5 Hz. Notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1 and ginsenoside Rd showed a good linear relationship in the range of 16.96-203.5 μg·mL-1 (R2 = 0.999 3), 54.46-653.5 μg·mL-1 (R2 = 0.999 3), 10.96-131.5 μg·mL-1 (R2 = 0.999 6), 51.50-618.0 μg·mL-1 (R2 = 0.999 0), 15.94-191.3 μg·mL-1 (R2 = 0.999 4), respectively. The average recoveries were 98.96%, 100.8%, 94.76%, 100.1%, 103.1%, and RSDs were 0.87%, 1.46%, 1.85%, 2.06%, 0.96% (n = 6), respectively. The proposed method is accurate, simple and reliable, and can be used for the determination of five saponins in Yaobitong capsule.

ABSTRACT

Objective@#Hypoglossal nerve-facial nerve 'side'-to-side neurorrhaphy is a new method for the treatment of potential incomplete facial paralysis after acoustic neuroma. However, there are differences in postoperative outcomes among patients. This study analysed preoperative factors that may influence the treatment outcomes of neurorrhaphy.@*Methods@#We performed a retrospective study of 53 patients who were treated by neurorrhaphy for facial paralysis after acoustic neuroma resection. After a one-year follow-up period, the patients were divided into two groups according to facial functional outcome: better recovery or ordinary recovery. We analysed the following factors: gender, age, tumour size, and characteristics, tumour adhesion to the facial nerve, the duration of facial paralysis (DFP) and F wave appearance prior to neurorrhaphy (F wave).@*Results@#Univariate analysis showed significant differences between the two groups in DFP ( = 0.0002), tumour adhesion to the facial nerve ( = 0.0079) and F waves ( = 0.0048). Logistic regression analysis of these factors also showed statistical significance with values of 0.042 for the DFP, 0.043 for F waves, and 0.031 for tumour adhesion to the facial nerve.@*Conclusions@#Tumour adhesion to the facial nerve, F waves appearance and DFP prior to neurorrhaphy are the predominant factors that influence treatment outcomes.

ABSTRACT

As next-generation sequencing (NGS) technology has become widely used to identify genetic causal variants for various diseases and traits, a number of packages for checking NGS data quality have sprung up in public domains. In addition to the quality of sequencing data, sample quality issues, such as gender mismatch, abnormal inbreeding coefficient, cryptic relatedness, and population outliers, can also have fundamental impact on downstream analysis. However, there is a lack of tools specialized in identifying problematic samples from NGS data, often due to the limitation of sample size and variant counts. We developed SeqSQC, a Bioconductor package, to automate and accelerate sample cleaning in NGS data of any scale. SeqSQC is designed for efficient data storage and access, and equipped with interactive plots for intuitive data visualization to expedite the identification of problematic samples. SeqSQC is available at http://bioconductor.org/packages/SeqSQC.

ABSTRACT

Objective To investigate the mechanism via which artesunate regulates the invasion and metastasis of colon cancer cells and the expression of members of the TGF-β1/Smad4 signaling pathway. Methods The cell counting kit 8 (CCK8), nude mouse xenograft model, Transwell invasion assay, and flow cytometry were used to investigate the effect of artesunate on the invasion and metastasis of colon cancer cells. Western blotting and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) were used to detect the expression of TGF-β1 and Smad4 proteins and mRNA, respectively. Results Artesunate inhibited the growth of transplanted tumor, cell proliferation, and invasion and promoted apoptosis. It inhibited TGF-β1 expression and promoted Smad4 expression. TGF-β1 inhibitors reversed the inhibitory effect of artesunate. Conclusion Artesunate can inhibit the growth of xenograft tumor in nude mice and its mode of action may be related to the TGF-β1/Smad4 signaling pathway.

ABSTRACT

Objective:To investigate the neuroprotective effect of minocycline on the secondary injury after acute closed spinal cord injury in rats. Methods:A total of 24 Sprague-Dawley male rats were randomly divided into saline group (n = 8), magnesium chloride group (n = 8) and minocycline group (n = 8). The closed spinal cord injury model was prepared with balloon compression in the dorsal spinal cord of rat, which was evaluated with magnetic resonance imaging. All rats were successively administered their own drugs for seven days after injury, respectively. They were assessed with BBB score two to 31 days after operation. Their motor-evoked potential and sensory-evoked potential were detected 31 days after operation, and then Luxol Fast Blue was used to observe the area of secondary injury. Results:Animal magnetic resonance imaging showed hypointense in T2 images in T10 spinal cord. BBB score was more in the minocycline group than in the saline group since 17 days after operation (P < 0.05). The amplitude of motor-evoked potential was higher in the minocycline group than in the saline group (P < 0.05), while the area of secondary injury was less (P < 0.05). Conclusion:Minocycline may protect the nerves from secondary injury after acute spinal cord injury.

ABSTRACT

Decoction pieces are the main body of traditional Chinese medicine (TCM) clinical medication. With the modernization of TCM medication, TCM formula granules have gradually developed and begun to take shape. Although there are processing forms of TCM injection and oral liquid, they only account for a small part of TCM market and are mainly taken orally. However, when oral administration of lipid soluble ingredients is conducted, the dissolution is limited and the absorption is relatively small. In addition, it has side effects of stimulating gastrointestinal tract, resulting in low tolerance of patients. Although there are topical preparations made by water extraction and alcohol extraction, most of them are crude preparations with random dosage, which results in the waste of lipid soluble components to a certain extent. Most of the lipid soluble components of TCM have good biological activities, such as schisandrin b, tanshinone, methyl chlorogenic acid, etc., but there is no suitable medicinal form. To make the best use of "medicine", it is necessary to systematically study the lipid soluble components of TCM. On the basis of fairly mature extraction, separation and collection processes, a medicinal form with definite pharmacological effect and beneficial to its absorption is developed based on lipid soluble components. TCM essential oil has anti-aging, anti-dementia, anti-oxidation and other activities, which has been widely used in clinical, cosmeceuticals, health products and other fields. However, the effect of single essential oil is limited. Compatibility can not only enhance the efficacy and reduce toxicity, but also expand the application range of essential oil. Therefore, formula essential oil can be used as a new form of TCM, and mainly for external use, supplemented by internal use, to make up for the disadvantages of crude preparations and random dosing for external use of TCM, as well as the disadvantages of orally absorbed less and stimulated gastrointestinal tract, to meet the needs of clinical medication, faster, more accurate, better and stronger play the effect of lipid soluble components.

Objective: To analyze the medication rules of traditional Chinese medicine (TCM) in treating type 2 diabetes mellitus (T2DM),and explore the mechanism of action.Method: The articlesabout TCM treatment for T2DM in CNKI and Wanfang Med Online were retrieved.The data was entered into Excel 2013 to set up a database,and the factor analysis,association rules and cluster analysis were used to analyze core medication combinations by SPSS Statistics 19.0 and SPSS Modeler 14.1.kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis was performed using BATMAN-TCM to reveal the mechanism of action.Result: A total of 92 prescriptions were included,the high frequency medicines were Astragali Radix.The major properties of TCM were cold and plain.The major flavors of TCM were sweet and bitter.The major meridian tropism of TCM was livermeridian.These high frequency medicines were deficiency-nourishing herbs,and blood circulation-invigorating and stasis-eliminating herbs.Totally 6 core medication combinations were mined through association rules.Seven common factors were extracted from factor analysis.Clustering analysis was used to get 6 kinds of herbs.KEGG pathway analysis revealed 24 biological pathways and 6 diseases relating to T2DM.Conclusion: The most commonly used Astragali Radix for treating T2DM.In clinical,it can be combined with Poria,Salviae Miltiorrhizae Radix et Rhizoma and Rehmanniae Radix for treating T2DM.At the same time,it can be combined with such herbs as deficiency-nourishing herbs,and blood circulation-invigorating and stasis-eliminating herbs.The mechanism of action of high-frequency herbs may be related to the targets of exophosphatase/phosphodiesterase (PDEs),adenosine A1 receptor gene 1(ADORA1),adenosine A2A receptor gene (ADORA2A),neuropetide second receptor (NPY2R),and endothelial carbon monoxide synthase (NOS3) by interfering with PI3K/Akt,starch and sucrose metabolism signaling pathways.
