ABSTRACT

The community teaching bases play an important role in training of general practice talents. To raise the training quality, the development of their own capacity is crucial, but community medical institutions also need close cooperation with the departments of general practice in medical schools and the higher-level general hospitals. This article discusses the integration model of management, teaching and research in general practice talent training based on the cooperation of community teaching bases with relevant governmental departments, professional societies/associations, general hospitals and medical schools.

ABSTRACT

Objective@#We aimed to investigate whether 2-[ 18F]fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (2-[ 18F]FDG PET/CT) can aid in evaluating the risk of malignancy in ampullary tumors detected by endoscopy. @*Materials and Methods@#This single-center retrospective cohort study analyzed 155 patients (79 male, 76 female; mean age, 65.7 ± 12.7 years) receiving 2-[ 18F]FDG PET/CT for endoscopy-detected ampullary tumors 5–87 days (median, 7 days) after the diagnostic endoscopy between June 2007 and December 2020. The final diagnosis was made based on histopathological findings. The PET imaging parameters were compared with clinical data and endoscopic features. A model to predict the risk of malignancy, based on PET, endoscopy, and clinical findings, was generated and validated using multivariable logistic regression analysis and an additional bootstrapping method. The final model was compared with standard endoscopy for the diagnosis of ampullary cancer using the DeLong test. @*Results@#The mean tumor size was 17.1 ± 7.7 mm. Sixty-four (41.3%) tumors were benign, and 91 (58.7%) were malignant. Univariable analysis found that ampullary neoplasms with a blood-pool corrected peak standardized uptake value in earlyphase scan (SUVe) ≥ 1.7 were more likely to be malignant (odds ratio [OR], 16.06; 95% confidence interval [CI], 7.13–36.18;P < 0.001). Multivariable analysis identified the presence of jaundice (adjusted OR [aOR], 4.89; 95% CI, 1.80–13.33; P = 0.002), malignant traits in endoscopy (aOR, 6.80; 95% CI, 2.41–19.20; P < 0.001), SUVe ≥ 1.7 in PET (aOR, 5.43; 95% CI, 2.00–14.72; P < 0.001), and PET-detected nodal disease (aOR, 5.03; 95% CI, 1.16–21.86; P = 0.041) as independent predictors of malignancy. The model combining these four factors predicted ampullary cancers better than endoscopic diagnosis alone (area under the curve [AUC] and 95% CI: 0.925 [0.874–0.956] vs. 0.815 [0.732–0.873], P < 0.001). The model demonstrated an AUC of 0.921 (95% CI, 0.816–0.967) in candidates for endoscopic papillectomy. @*Conclusion@#Adding 2-[ 18F]FDG PET/CT to endoscopy can improve the diagnosis of ampullary cancer and may help refine therapeutic decision-making, particularly when contemplating endoscopic papillectomy.

ABSTRACT

Hypoxia-inducible factor (HIF-1α), a core transcription factor responding to changes in cellular oxygen levels, is closely associated with a wide range of physiological and pathological conditions. However, its differential impacts on vascular cell types and molecular programs modulating human vascular homeostasis and regeneration remain largely elusive. Here, we applied CRISPR/Cas9-mediated gene editing of human embryonic stem cells and directed differentiation to generate HIF-1α-deficient human vascular cells including vascular endothelial cells, vascular smooth muscle cells, and mesenchymal stem cells (MSCs), as a platform for discovering cell type-specific hypoxia-induced response mechanisms. Through comparative molecular profiling across cell types under normoxic and hypoxic conditions, we provide insight into the indispensable role of HIF-1α in the promotion of ischemic vascular regeneration. We found human MSCs to be the vascular cell type most susceptible to HIF-1α deficiency, and that transcriptional inactivation of ANKZF1, an effector of HIF-1α, impaired pro-angiogenic processes. Altogether, our findings deepen the understanding of HIF-1α in human angiogenesis and support further explorations of novel therapeutic strategies of vascular regeneration against ischemic damage.

ABSTRACT

Network pharmacology, molecular docking, and in vivo and in vitro experiments were employed to study the molecular mechanism of Blaps rynchopetera Fairmaire in the treatment of non-small cell lung cancer(NSCLC). The components of B. rynchopetera were collected by literature review, and the active components were screened out through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). PharmMapper was used to obtain the targets of the active components. The targets of NSCLC were obtained from DrugBank, GeneCards, OMIM, TTD, and PharmGKB. The Venn diagram was drawn to identify the common targets shared by the active components of B. rynchopetera and NSCLC. The "drug component-target" network and protein-protein interaction(PPI) network were constructed by Cytoscape, and the key targets were screened by Centiscape. Gene Ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment of the above key targets were performed by DAVID. AutoDock and PyMOL were used for the molecular docking between the key targets and corresponding active components. A total of 31 active components, 72 potential targets, and 11 key targets of B. rynchopetera against NSCLC were obtained. The active components of B. rynchopetera had good binding activity with key targets. Further, the serum containing B. rynchopetera was prepared and used to culture human lung adenocarcinoma A549 cells. The CCK-8 assay was employed to determine the inhibition rates on the growth of A549 cells in blank control group and those exposed to different concentrations of B. rynchopetera-containing serum, cisplatin, and drug combination(B. rynchopetera-containing serum+cisplatin) for different time periods. The cell migration and invasion of A549 cells were detected by cell scratch assay and Transwell assay, respectively. Western blot was employed to determine the expression levels of B-cell lymphoma-2(Bcl-2), Bcl-2-associated X(Bax), caspase-3, cell division cycle 42(CDC42), proto-oncogene tyrosine-protein kinase SRC, and vascular endothelial growth factor(VEGF) in A549 cells. C57BL/6 mice were inoculated with Lewis cells and randomly assigned into a model control group, a B. rynchopetera group, a cisplatin group, and a drug combination(B. rynchopetera+cisplatin) group, with 12 mice per group. The body weight and the long diameter(a) and short diameter(b) of the tumor were monitored every other day during treatment, and the tumor volume(mm~3) was calculated as 0.52ab~2. After 14 days of continuous medication, the mice were sacrificed for the collection of tumor, spleen, and thymus, and the tumor inhibition rate and immune organ indexes were calculated. The tissue morphology of tumors was observed by hematoxylin-eosin(HE) staining, and the positive expression of Bax, Bcl-2, caspase-3, CDC42, SRC, and VEGF in the tumor tissue was detected by immunohistochemistry. The results indicated that B. rynchopetera and the drug combination regulated the expression levels of Bax, Bcl-2, caspase-3, CDC42, SRC, and VEGF to inhibit the proliferation, migration, and invasion of A549 cells and Lewis cells, thus playing a role in the treatment of NSCLC via multiple ways.

ABSTRACT

Progressive functional deterioration in the cochlea is associated with age-related hearing loss (ARHL). However, the cellular and molecular basis underlying cochlear aging remains largely unknown. Here, we established a dynamic single-cell transcriptomic landscape of mouse cochlear aging, in which we characterized aging-associated transcriptomic changes in 27 different cochlear cell types across five different time points. Overall, our analysis pinpoints loss of proteostasis and elevated apoptosis as the hallmark features of cochlear aging, highlights unexpected age-related transcriptional fluctuations in intermediate cells localized in the stria vascularis (SV) and demonstrates that upregulation of endoplasmic reticulum (ER) chaperon protein HSP90AA1 mitigates ER stress-induced damages associated with aging. Our work suggests that targeting unfolded protein response pathways may help alleviate aging-related SV atrophy and hence delay the progression of ARHL.

ABSTRACT

ObjectiveTo investigate whether the whole intestinal microbiota transplantation in Alzheimer's disease (AD) model mice has more significant effects on ileum intestinal microenvironment in normal mice under the guidance of the theory of traditional Chinese medicine that "interior-exterior relationship exists between the heart and small intestine". MethodsThe whole intestinal microbiota of fourteen 6-month-old specific pathogen free male APP/PS1 double-transgenic AD model mice was transplanted into the gut of six normal C57BL/6J mice of the same age and background treated with mixed antibiotics for 14 days. Then, after 14 days of normal rearing, the mice were sacrificed. Next, the pathological changes in the ileum and colon were observed, and the composition and diversity of the ileal and colonic microbiota was analyzed by sequencing. ResultsAfter the whole intestinal microbiota of AD mice was transplanted into normal mice, pathological analysis showed that only the ileum tissue had mucosal damage and crypt gland epithelial cell degeneration, necrosis, and shedding. Moreover, the microbiota analysis found that only the number of genera (P<0.01), Chao1 index (P<0.01) and Simpson index of ileal microbiota in normal mice decreased (P<0.01), and the composition of intestinal microbiota was quite similar to that of AD model mice. ConclusionUnder the effect of whole gut microbiota transplantation in AD mice, the diversity and composition of ileal microbiota change more than that of colonic microbiota in normal mice, and at the same time, it results in pathological damage to the ileal mucosa, indicating that the ileal microenvironment may be more closely related to the occurrence and development of AD, which is highly consistent with the traditional Chinese medicine theory of "interior-exterior relationship between heart and small intestine".

ABSTRACT

With the prevalence of myopia in Asia, the prevalence of high myopia is gradually increasing, and high myopia has undoubtedly become a public health problem in Asia and even around the globe. As a relatively common pathological change in the eyes of patients with high myopia, optic disc tilt may also become a risk factor for diseases such as glaucoma and macular degeneration, thereby increasing the risk of visual impairment. However, the mechanism of optic disc tilt in high myopia and the role of optic disc tilt in the aggravation of high myopia complications still needs to be further explored. Therefore, this article collects and organizes relevant literatures on optic disc tilt, and makes a comprehensive discussion on the mechanism of optic disc shape changing caused by high myopia and the impact on various complications, so as to provide a certain basis for clinical diagnosis and treatment of high myopia and its complications.

ABSTRACT

Objective@#The real-world INFORM study analyzed sociodemographics, treatment patterns and clinical outcomes for patients with newly diagnosed advanced epithelial ovarian cancer (EOC) in Australia, South Korea (S.Korea) and Taiwan preceding incorporation of poly(ADP-ribose) polymerase inhibitors into clinical practice. @*Methods@#Retrospective data from patients diagnosed with EOC (high-grade serous EOC for Taiwan) between January 2014 and December 2018 with ≥12 months follow-up from diagnosis were analyzed descriptively. Survival was evaluated by Kaplan-Meier with two-sided 95% confidence interval (CI). @*Results@#Of the 987 patients (Australia, 223; S.Korea, 513; Taiwan, 251), 98% received platinum-based chemotherapy (CT). In S.Korea and Taiwan 76.0% and 78.9% respectively underwent primary cytoreductive surgery; in Australia, 56.5% had interval debulking surgery. Bevacizumab was included in primary/maintenance therapy for 22.4%, 14.6% and 6.8% of patients in Australia, S.Korea and Taiwan, respectively. Patients receiving bevacizumab were high-risk (reimbursement policy) and achieved similar real-world progression-free survival (PFS) compared with CT only. Overall, the median real-world PFS (months; 95% CI) was similar across Australia (16.0 [14.63–18.08]), S.Korea (17.7 [16.18–19.27]) and Taiwan (19.1 [17.56–22.29]). @*Conclusion@#This study reveals poor prognosis despite differences in demographics and treatment patterns for patients with EOC across Asia-Pacific suggesting the need for biomarker-driven novel therapies to improve outcomes.

ABSTRACT

Objective@#Genetic high-risk assessment combines hereditary breast, ovarian and pancreatic cancer into one syndrome. However, there is a lack of data for comparing the germline mutational spectrum of the cancer predisposing genes between these three cancers. @*Methods@#Patients who met the criteria of the hereditary breast, ovarian and pancreatic cancer were enrolled and received multi-gene sequencing. @*Results@#We enrolled 730 probands: 418 developed breast cancer, 185 had ovarian cancer, and 145 had pancreatic cancer. Out of the 18 patients who had two types of cancer, 16 had breast and ovarian cancer and 2 had breast and pancreatic cancer. A total of 167 (22.9%) patients had 170 mutations. Mutation frequency in breast, ovarian and pancreatic cancer was 22.3%, 33.5% and 17.2%, respectively. The mutation rate was significantly higher in patients with double cancers than those with a single cancer (p<0.001). BRCA1 and BRCA2 were the most dominant genes associated with hereditary breast and ovarian cancer, whereas ATM was the most prevalent gene related to hereditary pancreatic cancer. Genes of hereditary colon cancer such as lynch syndrome were presented in a part of patients with pancreatic or ovarian cancer but seldom in those with breast cancer. Families with a history of both ovarian and breast cancer were associated with a higher mutation rate than those with other histories. @*Conclusion@#The mutation spectrum varies across the three cancer types and family histories. Our analysis provides guidance for physicians, counsellors, and counselees on the offer and uptake of genetic counseling.

ABSTRACT

Objective: To identify the antibiotic resistance, virulence genes, and sequence types of Pseudomonas aeruginosa (P. aeruginosa) strains isolated from blood. Methods: From November 2014 to December 2021, a total of 94 nonrepetitive P. aeruginosa isolates were obtained from blood samples of patients at the First Affiliated Hospital of Shandong First Medical University in Shandong Province, China. The bacteria were identified using matrix-assisted laser desorption ionization time of flight mass spectrometry. Antibiotic resistance of the P. aeruginosa isolates was detected using Vitek 2 Compact system. Polymerase chain reaction (PCR) was conducted for the 18 virulence genes, and multi locus sequence typing (MLST) was performed to identify the sequence types of the P. aeruginosa strains. The resistance rates and distributions of virulence genes between carbapenem resistant pseudomonas aeruginosa (CRPA) and carbapenem susceptible pseudomonas aeruginosa (CSPA) isolates were compared using the Chi-square test. Results: Among 94 P. aeruginosa isolates, 19 (20.2%) isolates were found to be multidrug resistant (MDR) bacteria, of which 17 were CRPA isolates and 2 were CSPA isolates. All strains contained more than 10 virulence genes. Except for exoU gene, the detection rate of other genes was above 83%. MLST analysis revealed a total of 66 different STs, including 59 existing STs and 7 novel STs. Among them, ST244 (n=11, 11.7%) and ST270 (n=7, 7.4%) were the dominant STs. Although these two types of isolates harbored the same virulence genes, the resistance rates to carbapenem were different. 54.5% (6/11) ST244 isolates were CRPA but all 7 ST270 isolates were CSPA. Conclusion: Although the resistance rates of P. aeruginosa strains isolated from blood were at a low level, some MDR and CRPA isolates were detected. As the high virulence gene detection rates and genetic diversity were found for P. aeruginosa strains isolated from blood, close attention should be paid to avoid transmission and outbreaks.

ABSTRACT

ObjectiveTo investigate the effect of Huangqisan pellets (HQS) on the phosphatidylinositol-3 kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway and autophagy in the kidney of diabetic nephropathy (DN) rats. MethodDN rat model was established through high-fat diet combined with intraperitoneal injection of streptozotocin (35 mg·kg-1). DN rats were randomly assigned into model group, irbesartan (0.027 g·kg-1) group, low-dose HQS (0.54 g·kg-1) group and high-dose HQS (1.08 g·kg-1) group. The levels of 24 h urinary total protein (UTP), serum albumin (Alb), serum creatinine (SCr), urea nitrogen (BUN), triglyceride (TG) and total cholesterol (TC) were measured after 12 weeks of continuous administration. The pathological changes of renal tissue were observed via hematoxylin-eosin (HE) staining. The expression of podocyte split diaphragm proteins nephrin and podocin in the renal tissue were detected by immunohistochemistry. The protein levels and phosphorylation of key proteins in PI3K/Akt/mTOR signaling pathway, as well as the expression of yeast Atg6 homolog (Beclin1) and microtubule-associated protein 1 light chain 3 (LC3) in the renal tissue were analyzed by Western blot. ResultCompared with the control group, the model group showcased increased 24 h UTP, SCr, BUN, TG, and TC levels and decreased Alb level (P<0.01). After modeling, the rats showed granulosity of epithelial cells of renal tubules, thickening of capillary basement membrane, proliferation of mesangial cells, and sclerosis of glomerulus. Furthermore, modeling down-regulated the expression of nephrin and podocin in the podocyte hiatus of glomerulus (P<0.01) as well as the protein levels of p-PI3K, p-Akt, and p-mTOR and the autophagy markers LC3 and Beclin1 in renal tissue (P<0.01). Compared with model group, irbesartan and HQS decreased the 24 h UTP, Cr, BUN, TG, and TC levels, increased the Alb level, and alleviated the pathological damage of kidney. Moreover, they up-regulated the expression of Nephrin and Podocin in the podocyte hiatus of glomerulus, as well as the protein levels of p-PI3K, p-Akt, p-mTOR, LC3, and Beclin1 in renal tissue (P<0.05, P<0.01). ConclusionHQS may inhibit the PI3K/Akt/mTOR signaling pathway to enhance podocyte autophagy and protect the glomerulus, thus slowing down the development of DN.

ABSTRACT

Objective@#Cytoreductive surgery followed by adjuvant chemotherapy is a standard frontline treatment for epithelial ovarian cancer (EOC). We aimed to develop an ovarian cancer risk score (OVRS) based on the expression of 10 ovarian-cancer-related genes to predict the chemoresistance, and outcomes of EOC patients. @*Methods@#We designed a case-control study with total 149 EOC women including 75 chemosensitives and 74 chemoresistants. Gene expression was measured using the quantitative real-time polymerase chain reaction. We tested for correlation between the OVRS and chemosensitivity or chemoresistance, disease-free survival (DFS), and overall survival (OS), and validated the OVRS by analyzing patients from the TCGA database. @*Results@#The chemosensitive group had lower OVRS than the chemoresistant group (5 vs.15, p≤0.001, Mann-Whitney U test). Patients with disease relapse (13 vs. 5, p60 months) of patients with OVRS ≥10 were significantly shorter than those of patients with OVRS <9). The high OVRS group also had significantly shorter median OS than the low OVRS group in 255 patients in the TCGA database (39 vs. 49 months, p=0.046). @*Conclusions@#Specific genes panel can be clinically applied in predicting the chemoresistance and outcome, and decision-making of epithelial ovarian cancer.

ABSTRACT

OBJECTIVE@#To observe the clinical effect of high suspension and low incision (HSLI) surgery on mixed haemorrhoids, compared with Milligan-Morgan haemorrhoidectomy.@*METHODS@#A multi-centre, randomized, single-blind, non-inferiority clinical trial was performed. Participants with mixed haemorrhoids from Xiyuan Hospital of China Academy of Chinese Medical Sciences, Beijing Rectum Hospital, Air Force Medical Center of People's Liberation Army of China, and Puyang Hospital of Traditional Chinese Medicine were enrolled from September 2016 to March 2018. By using a blocked randomization scheme, participants were assigned to two groups. The experimental group was treated with HSLI, while the control group was treated with Milligan-Morgan haemorrhoidectomy. The primary outcome was the clinical effect evaluated at 12 weeks after operation. The secondary outcomes included the number of haemorrhoids treated during the operation, pain scores, use of analgesics, postoperative oedema, wound healing, incidence of anal stenosis, anorectal manometry after operation, as well as surgical duration, length of stay and total hospitalization expenses. A safety evaluation was also conducted.@*RESULTS@#In total, 246 eligible participants were enrolled, with 123 cases in each group. There was no significant difference in the clinical effect between the two groups (100.00% vs. 99.19%, P>0.05). Compared with the control group, the number of external haemorrhoids treated during the operation and the pain scores after operation were significantly reduced in the experimental group (P0.05). The surgical duration and length of stay in the experimental group were significantly longer than those in the control group, and the total hospitalization expense was significantly higher than that in the control group (all P<0.05). No adverse events were reported in either group during the whole trial or follow-up period.@*CONCLUSION@#HSLI had the advantages of preserving the skin of anal canal completely, alleviating postsurgical pain and promoting rapid recovery after operation.

ABSTRACT

Mineral medicine is an indispensable part of traditional Chinese medicine and has a long history of application. Among them, mineral-based hemostatics have been widely applied for the treatment of various hemorrhagic diseases with extensive clinical experience and established efficacy. Gypsum Fibrosum (GF), a commonly used mineral medicine in clinical, can clear away heat, and relieve anxiety and thirst. Gypsum Ustum (GU) is the processed product of GF after calcining at high temperature. It is mainly composed of anhydrous calcium sulfate (CaSO4) with the functions of moisturizing, promoting muscle growth, astringent sores and hemostasis. GU is often used externally to treat ulcer, itching, eczema, water and fire scalds, trauma bleeding, etc. Studies on the mechanism of hemostasis have shown that Ca2+ (coagulation factor Ⅳ) is involved in many key processes of the internal and external coagulation cascades and can prevent bleeding by regulating platelet activation and aggregation, and promoting the production of insoluble fibrin and the ultimate formation of a blood clot. GF and GU both contain Ca2+ which provide an important material basis of hemostatic effect for both compounds, but GU has a significant hemostatic effect, while GF has no hemostatic effect. After processing, the taste and efficacy of the GF have been obviously changed which reflects the characteristics of processing, but the processing mechanism of GU has not been fully clarified. Therefore, based on studies of GF before and after calcining, this paper focused on these aspects including calcining process, crystal form comparison, element content, efficacy comparison, and summarized various aspects of Ca2+ involved in hemostasis. In addition, the hemostatic properties of other calcium-containing mineral medicines and new calcium-containing hemostatic materials such as calcium alginate, mesoporous calcium silicate and nanogel hemostatic materials were also discussed. The paper aimed to provide a reference for elucidating processing mechanism and clinical dialectical use of GU, also to promote development of new calcium-containing hemostatic materials.
