ABSTRACT

Aim To discover the potential active compounds and possible mechanisms in rheumatoid arthritis (RA) treatment with Zhi-Huang-Zhi-Tong powder (ZHZTP) by using network pharmacology and in vitro study. Methods The active ingredient targets and disease targets of Zhihuang Zhitong Powder were searched and screened by database; they intersected to get a common target; and the "drug-component-target" relationship network diagram was constructed for GO and KEGG enrichment analysis of the overlapping genes; then the core components were docked with the core targets. Finally, based on the inflammation model of HUVECs in vitro, the efficacy and mechanism of Zhihuang Zhitong powder were verified by MTT method, plate scratch test and Western blot. Results Active compounds involved in RA treatment were screened in the present study, and the top two were ursolic acid and emodin, all playing crucial roles in RA treatment with ZHZTP. Additionally, the key target was AKTA, TNF and IL-6. GO and KEGG enrichment analysis revealed that ZHZTP regulated BP, MF and CC, and also focused on regulating AKTA, TNF and IL-6 signaling pathway. Molecular docking showed that interactions between key active compounds and key targets were stable. In vitro ZHZTP significantly inhibited cell viability and migration of TNF-a-stimulated HUVECs, and the involved mechanism may be associated with PI3K/AKT/m-TOR signaling. Conclusions The present study reveals that the potential active compounds of ZHZTP are ursolic acid and emodin, and moreover, the involved mechanisms of ZHZTP for RA treatment are associated with PI3 K/AKT/m-TOR signaling.

ABSTRACT

Objective To investigate the infection of Chlamydia pneumoniae and mycoplasma pneumoniae in adults and their association with atherosclerosis,and to provide theoretical guidance for the prevention of such diseases. Methods A case-control study was used to collect 362 patients who were diagnosed with atherosclerosis from January 2019 to December 2021 in Department of Sichuan Bazhong Central Hospital, and 370 cases who were admitted to the hospital during the same period of physical examination without any cardiovascular disease were selected as the control group, and whole blood samples of the two groups of study subjects were collected, and the infection of Chlamydia pneumoniae and mycoplasma pneumoniae was detected by PCR. Results The infection rate of Chlamydia pneumoniae was 35.49%, the infection rate of mycoplasma was 40.37%, and the co-infection rate was 11.37%;The infection rate of Chlamydia pneumoniae in the control group was 12.04%, the infection rate of mycoplasma was 15.83%, and the coinfection rate was 3.14%, and the difference between the two groups was statistically significant ( χ2=10.926, P=0.023). The effects of mycoplasma, chlamydia, and co-infection on atherosclerotic patients have sex differences, mainly manifested as higher infection rates in men; In addition, the effects of mycoplasma, chlamydia, and co-infection on atherosclerosis patients varied by age, mainly in the 55-70 years age group (P<0.05). Multivariate logistic regression results showed that Chlamydia pneumoniae infection was a risk factor for atherosclerosis (OR=1.303, 95%CI: 1.043-1.677) in the whole population, and chlamydia pneumoniae (OR=1.472, 95% CI: 1.037-1.556), mycoplasma (OR=2.003, 95%CI: 1.637-3.842) and co-infection in men (OR=1.937, 95%CI: 1.380-2.184) were risk factors for atherosclerosis, while co-infection in women (OR=1.699, 95%CI: 1.263-1.765) was a risk factor for atherosclerosis. Conclusion Chlamydia pneumoniae and mycoplasma infection are risk factors for atherosclerosis, and their impact on male groups is greater, and more attention needs to be paid to them.

ABSTRACT

Diabetic retinopathy(DR)is the most common microvascular complication of patients with diabetes mellitus, and it has become one of the leading causes of visual impairment among working-age people worldwide. The pathogenesis of DR is complicated with multiple mechanisms. Plenty of studies have indicated that circadian rhythm and clock genes are closely related to the pathogenesis of DR. Circadian rhythm is a physiological process regulated by clock genes, which takes 24h as a cycle and is consistent with the changes of light and dark outside. Circadian rhythm regulates various physiological activities of the body. The disturbance of circadian rhythm induces DR by affecting the blood glucose level and the physiological homeostasis of the eye in patients with diabetes mellitus, and clock genes may be involved in the pathogenesis of DR by regulating oxidative stress response, inflammatory response, retinal autophagy rhythm, mitochondrial dysfunction and endothelial progenitor cell function. This paper will introduce the generation and regulation mechanism of circadian rhythm, as well as the internal circadian rhythm of retina, and further discuss the influence of circadian rhythm and clock genes on the occurrence and development of DR, aiming to provide a reference for the prevention and treatment of DR.

ABSTRACT

Obesity is a chronic, recurrent, and progressive metabolic disorder characterized by the abnormal or excessive accumulation of body fat caused by multiple factors such as genetics, dietary structure, lifestyle and behavior, psychology, environment, and society, leading to an energy surplus. Obesity is a major risk factor that increases the risk of developing various chronic diseases, including type 2 diabetes, hypertension, cardiovascular diseases, stroke, and certain malignancies. The global incidence of obesity is increasing year by year. With the continuous improvement of people's living standards, more than half of adults in China are now overweight or obese, posing a serious threat to people's health and increasing the social and economic burden. It has become a pressing major public health issue that needs to be addressed urgently. The concept of obesity can be traced back to the Huangdi’s Internal Classic (Huang Di Nei Jing), which describes it as "the problems in fat and affluent people are caused by excessive taking of rich food", and suggests that ''frequent intake of rich and greasy foods can produce interior heat. Sweet flavor causes chest fullness. That is why its spleen-Qi flows upwards and changes into consumption-thirst disease. It can be treated by Eupatorii Herba which is used to remove stagnant Qi''. The stagnant qi is caused by the transformation failure of rich and greasy food and wine, so obesity is the disease of stagnant qi. Obesity is caused by indulging in rich and greasy food, wine, spicy and flavorful foods, raw and cold foods, and sweet and greasy foods, or overeating and leading a sedentary lifestyle, staying up late, or experiencing emotional imbalances such as excessive joy, anger, worry, pensiveness, and fear. It can also be caused by congenital abnormalities, leading to improper functioning of the spleen and stomach, dysregulation of the absorption and secretion of the small intestine, and the accumulation of stagnant Qi in the organs and muscles, resulting in a plump physique. The intake of food and drink depends on the functions of the stomach in receiving and decomposing, the small intestine in absorbing and secreting, and the spleen in transforming and transporting. The affected organs in obesity are the spleen, stomach, and small intestine. Orchids, specifically Eupatorii Herba and Lycopi Herba, are aromatic herbs that can regulate the smooth flow of Qi, eliminate stagnation, and cleanse impurities. In a broader sense, any aromatic and pungent substance that can invigorate the spleen, promote clarity, harmonize the stomach, reduce turbidity, and assist in the normal secretion and absorption functions of the small intestine, thereby eliminating excess, is referred to as orchid. Therefore, the treatment principle for obesity is to use ''orchids to eliminate stagnant Qi'', aiming to regulate the functions of the spleen, stomach, and small intestine using aromatic and pungent substances, gradually eliminating excessive dampness, phlegm, turbidity, and heat, and restore the balance of the middle energizer. This way, individuals who are obese can achieve a non-obese state.

ABSTRACT

Disintegration time is a key parameter that affects the palatability and compliance of oral soluble films. At present, there is no standard method to determine the disintegration time of oral soluble films. In this study, we compared the six methods (pharmacopoeial disintegration method, petri dish method, sponge surface method, slide frame and ball method, partially immersed into liquid (without weight attached) and partially immersed into liquid (with weight attached)) to determine the in vitro disintegration time of oral soluble films with different thickness, and evaluated the correlation with the in vivo disintegration time. The results showed that the repeatability and correlation of pharmacopoeial disintegration method and the partially immersed into liquid method (with weight attached) were excellent, with the endpoint of disintegration testing easy to determine. Partially immersed into liquid method (with weight attached), properly simulating the physiological condition in oral cavity, showed strong operability, good repeatability and in vitro-in vivo correlation, and was suitable for in vitro disintegration evaluation of oral soluble film dosage form. The adult sensory evaluation study was a research-based clinical trial conducted with informed consent from all subjects in accordance with the ethical requirements of Good Clinical Practice.

ABSTRACT

Licorzine granules are common preparations for children zinc deficiency. Considering the long course of treatment, the taste of licorzine granules may become a main factor affecting medication adherence. To date there have been no taste evaluation research into licorzine granules yet. In this study, both sensory evaluation and electronic tongue method were utilized to optimize licorzine granules formulations, evaluate the tastes of licorzine, excipients, optimized formulation in vivo and in vitro. As the results show, bitterness and astringency are the main unpleasant tastes generating from licorzine. Xanthan gum is the main taste-masking excipient, lowering down the bitterness and astringency of licorzine by at least one grade. Good correlation exists between the results of sensory evaluation and electronic tongue method, and an integrated combination of the two helps to obtain objective and rational research conclusions. The adult sensory evaluation study was a research-based clinical trial conducted with informed consent from all subjects in accordance with the ethical requirements of Good Clinical Practice.

ABSTRACT

Glaucoma is a chronic optic neuropathy that affects the retinal ganglion cells, characterized by optic disc atrophy, visual field defects, and visual acuity loss. Since glaucoma is a chronic disease, long-term use of topical intraocular pressure-lowering medications often leads to ocular surface diseases, thus reducing medication adherence and ultimately affecting treatment efficacy. Currently, topical intraocular pressure-lowering medications include prostaglandin derivatives, β-adrenergic blockers, α-adrenergic agonists, topical carbonic anhydrase inhibitors, and cholinergic drugs. This article provides a comprehensive review of the effects and related mechanisms of these five antiglaucoma medications on the ocular surface of glaucoma patients and offers preventative measures for the protection of ocular surface in glaucoma patients.

ABSTRACT

Objective:To establish and validate a prognosis prediction model of gall bladder cancer after surgery based on the albumin-bilirubin (ALBI) grade.Methods:The clinicopathological data of 161 patients with gallbladder cancer undergoing radical surgery in the First Hospital of Jiaxing between March 2011 to January 2020 were retrospectively analyzed, including 44 males and 117 females, aged (65±9) years old. The patients were grouped by the levels of ALBI score. The survival data were obtained through telephone or outpatient review. The Kaplan-Meier method was used to draw the survival curve. Multivariate analysis was performed using the Cox regression analysis model. The time-dependent receiver operating characteristic (ROC) curve was plotted to compare the prognostic value of the scoring system. A nomogram based on ALBI grade was established and its predictive performance was evaluated.Results:The 1, 3, 5 years overall survival (OS) rates of patients with gallbladder cancer were 76.7%, 52.5%, and 41.9%, respectively. The time-dependent ROC curves revealed that the area under the curve (AUC) values of ALBI grade were 0.659, 0.597 and 0.599 for 1, 2 and 3 years, showing a good prognostic performance. Multivariate regression analysis showed that poorer tumor differentiation ( HR=2.890, 95% CI: 1.816-4.600, P<0.001), TNM Ⅲ/Ⅳ stage ( HR=2.832, 95% CI: 1.781-4.503, P<0.001), ALBI grade 2 ( HR=1.595, 95% CI: 1.017-2.500, P=0.042), and ALBI grade 3 ( HR=3.938, 95% CI: 1.375-11.278, P=0.011) were independent risk factors for OS. The nomogram established with the independent risk factors such as ALBI grade showed a good predictive value for OS. The ROC curve results showed that the AUC values for 1, 3 and 5 years were 0.796, 0.806 and 0.799, respectively. The calibration plots and clinical decision curve analysis (DCA) showed the clinical feasibility of this nomogram. Conclusion:The nomogram model based on ALBI grading has a good predictive value for gallbladder cancer after surgery, which could guide the prognosis and individualized treatment decision-making.

ABSTRACT

Objective:To explore the accuracy of artificial intelligence (AI) system based on deep learning in evaluating bone age of children with abnormal growth and development.Methods:The positive X-ray films of the left wrist of children with abnormal growth and development who were treated at the Affiliated Hospital of Guizhou Medical University from January 2020 to December 2021 were collected retrospectively. A total of 717 children were collected, including 266 males and 451 females, aged 2-18 (11±3) years. Based on Tanner Whitehouse 3 (TW 3)-RUS (radius, ulna, short bone) and TW3-Carpal (carpal bone) method, bone age was measured by 3 senior radiologists, and the mean value was taken as reference standard. The bone ages were independently evaluated by the AI system (Dr.Wise bone age prediction software) and two junior radiologists (physicians 1 and 2). The accuracy within 0.5 year, the accuracy within 1 year, the mean absolute error (MAE) and the root mean square error (RMSE) between the evaluation results and the reference standard were analyzed. Paired sample t-test was used to compare MAE between AI system and junior physicians. Intraclass correlation coefficient (ICC) was used to evaluate the consistency between AI system, junior physician and reference standard. The Bland-Altman diagram was drawn and the 95% consistency limit was calculated between AI system and reference standard. Results:For TW3-RUS bone age, compared with the reference standard, the accuracy within 0.5 year of AI system, physician 1 and physician 2 was 75.3% (540/717), 62.1% (445/717) and 66.2% (475/717), respectively. The accuracy within 1 year was 96.9% (695/717), 86.3% (619/717) and 89.1% (639/717), respectively. MAE was 0.360, 0.565 and 0.496 years, and RMSE was 0.469, 0.634 and 0.572 years, respectively. For TW3-Carpal bone age, compared with the reference standard, the accuracy within 0.5 year of AI system, physician 1 and physician 2 was 80.9% (580/717), 65.1% (467/717) and 71.7% (514/717), respectively. The accuracy within 1 year was 96.0% (688/717), 87.3% (626/717) and 90.4% (648/717), respectively. MAE was 0.330, 0.527 and 0.455 years, and RMSE was 0.458, 0.612, 0.538 years, respectively. Based on TW3-RUS and TW3-Carpal bone age, the MAE of AI system were lower than those of physician 1 and physician 2, and the differences were statistically significant ( P all<0.001). The evaluation results of AI, physician 1 and physician 2 were in good agreement with the reference standard (ICC all>0.950). The Bland-Altman analysis showed that the 95% agreement limits of AI system for assessing TW3-RUS and TW3-Carpal bone age were -0.75-1.02 years and-0.86-0.91 years, respectively. Conclusion:The accuracy of AI system in evaluating the bone age of children with abnormal growth and development is close to that of senior doctors, better than that of junior doctors, and in good agreement with senior doctors.

ABSTRACT

Diabetic ketoacidosis (DKA), a serious acute complication of diabetes mellitus, mainly manifests as hyperglycemia, ketosis, and acidosis. It is a metabolic syndrome resulting from insulin deficiency and increased insulin-antagonistic hormone levels. While type 2 diabetes mellitus complicated by DKA is relatively uncommon, secondary pneumomediastinum in DKA is extremely rare. Following alveolar rupture, air can travel through various routes to reach the hilum, causing anterior, middle, or posterior pneumomediastinum or even leading to intracranial epidural pneumatosis. The diagnosis of pneumomediastinum is mainly dependent on chest computed tomography findings. After the successful treatment of DKA, pneumomediastinum usually resolves spontaneously within 5-10 days with a good prognosis. One DKA patient admitted to Dege County People's Hospital developed Kussmaul respirations, followed by an increase in intra-alveolar pressure, an elevation in intra and extra-alveolar pressure difference, and protein decomposition in the alveolus wall, which promoted alveolar rupture and induced mediastinal emphysema. After rapid fluid replacement, blood glucose control with insulin, and maintenance of acid-base balance (correction DKA), the mediastinal emphysema was spontaneously absorbed. Through the analysis of the clinical data of this case, the purpose is to improve the clinicians' internal understanding of the relationship between mediastinal emphysema and DKA, avoid over-examination and over-treatment, and provide strategies for correct diagnosis and treatment.

ABSTRACT

Objective:To investigate the expression and significance of programmed death ligand 1 (PD-L1) and programmed death 1 (PD-1) in colorectal cancer complicated by schistosomiasis.Methods:A total of 134 patients with colorectal cancer who received treatment in Xuancheng People's Hospital during 2014-2021 were included in this study. These patients consisted of 74 patients with colorectal cancer combined with schistosomiasis (patient group) and 60 patients with only colorectal cancer (control group). The expression of PD-L1 and PD-1 in colorectal cancer tissue was detected by an immunohistochemical method. The differences in PD-L1 and PD-1 expression were compared between the two groups. The relationships between PD-L1 and PD-1 expression and clinical pathological characteristics were determined.Results:The positive expression rates of PD-L1 and PD-1 in cancer cells and interstitial lymphocytes were 55.4% and 60.8% respectively in the patient group and they were 35.0% and 40.0% respectively in the control group. The positive expression rates of PD-L1 and PD-1 were significantly higher in the patient group than the control group ( χ2 = 5.55, 5.74, both P < 0.05). The expressions of PD-L1 and PD-1 in the patient group were correlated with lymph node metastasis and high tumor-node-metastasis stage ( P < 0.05). Conclusion:PD-L1 and PD-1 are highly expressed in colorectal cancer complicated by schistosomiasis and are related to their invasive behavior. PD-1/PD-L1 singaling pathway may be involved in the molecular mechanism underlying the occurrence and development of colorectal cancer complicated by schistosomiasis. Blocking PD-1/PD-L1 signaling pathway may be a new strategy for immunotherapy of colorectal cancer complicated by schistosomiasis.

The research group adopted the electronic "Spot" mind mapping teaching method: ①Grouping: the students were divided into groups, 6 to 8 people in each group, a total of 16 groups. ②Preparation: each group established a WeChat group, and teachers guided them download the Mindmanager software and learn its mapping method. ③In class: each kidney disease unit was divided into 3 sessions. In the first class, based on what the instructor taught, the students summarized the contents and drew a mind map, and then explain their understanding according to the map. In the second class, "Spot" in the group was conducted based on standards, reading each other in the group, actively discussing with each other, further improving and reconstructing the core knowledge points of the chapter, and encouraging each student to actively participate in enhancing their subjective initiative in learning. In the third class, teachers evaluated students according to their learning situation, and students filled in the gaps according to their opinions, perfected their mind maps, and finally posted to the WeChat group. ④Review: the final versions were sent to the WeChat groups as review materials, which was convenient for learning together. SPSS 24.0 was used for Chi-square test.Results:There was no significant difference between the two groups before study ( P>0.005). After the research, the scores of theory test ( t=2.52, P=0.015), clinical skill test ( t=2.22, P=0.034) and total score ( t=3.53, P=0.003) in the experimental group were significantly higher than those in the control group ( P<0.05). There was no significant difference in the scores of critical thinking ability between the two groups before research ( P>0.05). Six months after research, the total scores of critical thinking ability in the experimental group were significantly higher than those in the control group ( P<0.05). Conclusion:The introduction of electronic "Spot" mind mapping teaching method into clinical practice teaching can realize the cross-linking of related knowledge points and systematize the knowledge. At the same time, it is interesting and can stimulate students' learning interest, and is helpful to cultivate the clinical critical thinking ability of students.

Sixty four patients with DPN were enrolled in the DPN group, and the remaining 436 patients were enrolled in the no-DPN group. The clinical data and the results of MNSI scale, pain, touch and temperature detection thresholds and VPT of the two groups were compared. Receiver operating characteristic (ROC) curve was drawn to analyze the clinical value of single and combined examination indicators in the diagnosis of DPN.Results:MNSI symptom questionnaire score and MNSI physical examination score in DPN group were higher than those in no-DPN group: (3.00 ± 1.35) scores vs. (1.69 ± 0.52) scores, (1.57 ± 0.50) scores vs. (1.01 ± 0.24) scores; the proportion of touch regression, pain regression and temperature regression was significantly higher than that in no-DPN group; and the levels of VPT in the DPN group was higher than that in the no-DPN group: (26.34 ± 5.03) V vs. (17.97 ± 6.82) V, there were statistical differences ( P<0.01). When the single index was diagnosed, the area under the curve (AUC) value of VPT was the highest (0.825), and significantly higher than the pain, touch and temperature detection ( P<0.01). The AUC value of VPT + MNSI in combined diagnosis was the highest (0.738), and the sensitivity and specificity of DPN diagnosis were 51.56% and 96.10%, respectively. Conclusions:Compared with MNSI scale score, sensory detection such as pain, touch and temperature, VPT has the best diagnostic efficiency for DPN, while combined with MNSI, the specificity can be further improved, but the sensitivity decreases, which is worthy of clinical attention.

ABSTRACT

Objective To investigate the effect of microRNA (miR)-138 regulation of Wnt signaling pathway on the biological behavior of human glioma cells in vitro. Methods Glioma cell lines U-87MG and U251 were selected and randomly divided into blank group, miR-NC group, miR-138 mimics group and miR-138 inhibitor group. Real-time PCR was used to detect the miR-138 expression in each group; MTT, flow cytometry, Transwell assay and scratch assay were used to detect proliferation, apoptosis, invasion and migration ability of each group respectively, and Western blotting was used to detect Wnt pathway-related protein expression in each group. Results The miR-138 expression level was higher in the miR-138 mimics group compared with the remaining 3 groups, and that in the miR-138 inhibitor group was lower than that in the blank group and the miR-NC group (P<0. 05) ; Compared with the blank group, the cell proliferation rate was lower in the miR-138 mimics group and higher in the miR-138 inhibitor group, and was time-dependent (P<0. 05) ; The apoptosis rate in the miR-138 mimics group was higher than that in the blank group, miR-NC group, and miR-138 inhibitor group, while the apoptosis rate in the miR-138 inhibitor group was lower than that in the rest other groups (P<0. 05) ; The number of cell-invading cells in the miR-138 mimics group was lower than that in the blank group, miR-NC group, and miR-138 inhibitor group, while all miR-138 inhibitor group were higher than the remaining three groups (P<0. 05) ; The cell migration rate of miR-138 mimics group was lower than that of blank group, miR-NC group and miR-138 inhibitor group, while all miR-138 inhibitor group were higher than the remaining three groups (P<0. 05) ; Wnt3a, Wntl, glycogen synthase kinase 3(3(GSK-3(3) and (3-catenin protein expression in the miR-138 mimics group was lower than that in the blank group, miR-NC group, and miR-138 inhibitor group; While miR-138 inhibitor groups were higher than the remaining three groups(P<0. 05). Conclusion MiR-138 overexpression effectively inhibite the proliferation, invasion and migration of glioma cells and promote their apoptosis, probably achieved by pathway inhibition of the Wnt signaling pathway.
