ABSTRACT
OBJECTIVE@#High-fat diet is one of the main risk factors that disrupt the balance of gut microbiota, which eventually will induce colorectal cancer (CRC). Evodiamine (EVO) is a wildly used multifunctional traditional Chinese medicine extract. In this study, we investigated the role of gut microbiota in high-fat diet-propelled CRC and the potential of EVO for CRC chemoprevention.@*METHODS@#Gut microbiota, serum d-lactic acid and endotoxin from 38 patients with colon cancer and 18 healthy subjects were detected by quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA). In addition, body mass index, phospho-signal transducer and activator of transcription 3 (p-STAT3) expression in cancer tissues and paracancerous tissues were detected by immunohistochemistry. A mouse intestinal inflammatory tumor model was established by azomethane/sodium dextran sulfate, followed by treatment with EVO and 5-aminosalicylic acid (ASA). Gut microbiota and inflammatory factors were detected by quantitative polymerase chain reaction, while serum d-lactic acid and endotoxin were detected by ELISA. Furthermore, cell proliferation, cell apoptosis, and interleukin (IL)-6/STAT3/P65 pathway were evaluated by 5-ethynyl-2'-deoxyuridine, terminal-deoxynucleotidyl transferase-mediated nick-end labeling, and Western blot assays.@*RESULTS@#In patients with colon cancer, the numbers of Enterococcus faecalis and Escherichia coli were increased, while those of Bifidobacterium, Campylobacter and Lactobacillus were decreased. Serum endotoxin and d-lactic acid levels and p-STAT3 levels were significantly increased. In the mouse model, both EVO and ASA inhibited tumor formation, decreased the proliferation of tumor cells, and induced apoptosis of tumor cells. Compared with the control group, the numbers of E. faecalis and E. coli were decreased, while Bifidobacterium, Campylobacter and Lactobacillus numbers were increased. In the EVO group, serum endotoxin and d-lactic acid levels and inflammatory factors were significantly decreased. Further, the IL6/STAT3/P65 signaling pathway was inhibited in the EVO group.@*CONCLUSION@#EVO may inhibit the occurrence of colon cancer by regulating gut microbiota and inhibiting intestinal inflammation. The potential mechanism involves inhibition of the IL6/STAT3/P65 signaling pathway, revealing its potential therapeutic significance in clinical applications.
ABSTRACT
Objective:To explore the effect of transcatheter chemoembolization (TACE) on recurrence and survival time of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) following curative resection.Methods:Of 724 HBV-related HCC patients who underwent curative resection in the Third Affiliated Hospital of Naval Military Medical University from October 2009 to August 2010 were retrospectively analyzed. Patients who underwent resection only and no recurrence within 3 months after surgery were classified into control group, while those received adjuvant TACE were classified into intervention group. The patients were further divided into 4 sub-groups according to tumor size, tumor number and tumor thrombus which were defined as risk factors for recurrence. Tumor diameter ≤5 cm with low or high risk factors (tumor number ≥2 or presence tumor thrombus) were in group 1 and group 2 respectively, tumor diameter >5 cm with low or high risk factors for recurrence were in group 3 and group 4 respectively.Results:A total of 354 patients were classified in the control group and 370 patients were classified in the TACE group. Adjuvant TACE showed an overall survival benefit in patients with tumor diameter >5 cm and presenting high risk factors, the 1-, 3-, and 5-year cumulative survival rates were 90.1%, 67.6%, and 46.5%, respectively, for the lip-TACE group 83.3%, 52.4%, and 33.3%, respectively, for the control group ( P<0.05). Patients with the tumor diameter ≤5 cm, there was no significant difference in cumulative survival between the TACE group and the control group regardless of the risk level ( P>0.05). There was no significant difference in recurrence curve between TACE group and control group in each stratum. Conclusions:Adjuvant TACE had no preventive effect on recurrence, but TACE can prolong the survival time of HCC patients with high risk factors for recurrence.
ABSTRACT
Objective:To explore the clinical characteristics, diagnosis and treatment of allergic bronchopulmonary aspergillosis(ABPA) with eosinophilic granulomatous with polyvasculitis(EGPA) as a comorbidity.Methods:We collected the clinical data of a patient with EGPA who sought treatment with ABPA as a comorbidity. We summarized the diagnosis and treatment process of the patient, and reviewed the literature. After that, we discussed the relationship between the pathogenesis of ABPA and EGPA and the diagnosis and treatment experience.Results:A 61-year-old male patient suffered from repeated coughing, expectoration, hemoptysis, wheezing. His blood eosinophils count and immunoglobulin (Ig)E level were elevated. He was tested positive for aspergillus fumigatus. His Computer Tomography (CT) showed pulmonary nodules and bronchiectasis. He was diagnosed as ABPA. He also suffered limb numbness, sinusitis, and renal dysfunction and was diagnosed as EGPA. His condition improved after treatment with glucocorticoids, immunosuppressants and antifungal agents. We reviewed the relevant literature and retrieved 10 case reports, of which 5 cases were diagnosed as ABPA first and then EGPA, 3 cases were diagnosed as EGPA first and then ABPA, 2 cases were diagnosed simultaneously. We found that there was a certain correlation between them in the pathogenesis, and the main treatment is glucocorticoids, immunosuppressants and antifungal drugs.Conclusion:ABPA with EGPA as a comorbidity is rarely reported, which reminds us that when diagnosing one of the diseases in clinical work, we should be alert to the coexistence of another disease to avoid misdiagnosis.
ABSTRACT
Cystic echinococcosis (CE) is a zoonotic infection caused by Echinococcus granulosus larvae. It seriously affects the development of animal husbandry and endangers human health. Due to a poor understanding of the cystic fluid formation pathway, there is currently a lack of innovative methods for the prevention and treatment of CE. In this study, the protoscoleces (PSCs) in the encystation process were analyzed by high-throughput RNA sequencing. A total of 32,401 transcripts and 14,903 cDNAs revealed numbers of new genes and transcripts, stage-specific genes, and differently expressed genes. Genes encoding proteins involved in signaling pathways, such as putative G-protein coupled receptor, tyrosine kinases, and serine/threonine protein kinase, were predominantly up-regulated during the encystation process. Antioxidant enzymes included cytochrome c oxidase, thioredoxin glutathione, and glutathione peroxidase were a high expression level. Intriguingly, KEGG enrichment suggested that differentially up-regulated genes involved in the vasopressin-regulated water reabsorption metabolic pathway may play important roles in the transport of proteins, carbohydrates, and other substances. These results provide valuable information on the mechanism of cystic fluid production during the encystation process, and provide a basis for further studies on the molecular mechanisms of growth and development of PSCs.
ABSTRACT
BACKGROUND@#The relationship of uric acid (UA) with the thyroid function among healthy individuals remains unclear. We aimed to examine the relationship between UA contents and thyroid hormone levels in healthy Chinese individuals.@*METHODS@#This was a cross-sectional study of 1186 Chinese adults (736 men and 450 women) who underwent a health check-up at the Huadong Hospital Affiliated to Fudan University (Shanghai, China) between January 1, 2010 and July 31, 2018. Clinical and thyroid hormone levels were compared in different UA groups (in male and menopause women groups, MG1: UA < 5 mg/dL; MG2: 5 mg/dL ≤ UA< 7 mg/dL; and MG3: UA ≥ 7 mg/dL; in female groups, FG1 to FG3 represent the UA levels of <4 mg/dL, 4 mg/dL ≤ UA< 6 mg/dL, and ≥6 mg/dL, respectively). In addition, natural cubic spline regression, together with Pearson correlation analysis, was performed in investigating the correlation of UA with thyroid hormones.@*RESULTS@#After adjusting for confounding factors, low levels of UA (for males, UA < 5.30 mg/dL; for females, UA < 4.05 mg/dL) were negatively correlated with free triiodothyronine (FT3) both in men and women. UA levels between 4.83 and 6.06 mg/dL may act to protect FT3 in women, while UA levels between 6.39 and 7.09 mg/dL may protect FT3 in men. FT3 levels of low-range UA group reduced compared with mid-range UA and the high-range UA groups in both men and women.@*CONCLUSIONS@#Our results provide epidemiologic evidence to support the negative correlation between low UA contents and FT3 in the Chinese Han population, suggesting that the reduced UA contents may serve as the risk factor to predict poor thyroid function in Chinese individuals.
ABSTRACT
OBJECTIVES@#To investigate whether necrostatin-1 (Nec-1) can protect islet cells from the damage induced by TNF-α.@*METHODS@#After isolation and purification, the neonatal porcine islet cell clusters (NICCs) were divided into 3 groups (islets 10 000 IEQ/group): a Nec-1 group (Nec-1+TNF-α was added to the culture medium), a TNF-α group (TNF-α was added to the culture medium), and a control group (pure medium). The number of cells was observed after 48 h of co-culture. The cell death was evaluated by AO/EB staining. Insulin secretion and DNA of islets were detected by chemiluminescence and nucleic acid quantitative analysis. RT-PCR assay was used to examine the mRNA expressions of insulin gene, glueogan gene and somatostatin gene. Flow cytometry analysis was used to detect the viability of B cells.@*RESULTS@#The number of islets in Nec-1 group, TNF-α group and the control group were (8 425±2 187), (4 325±778), and (7 122±1 558) IEQ, respectively. Compared to the other two groups, the number of dead cells in TNF-α group was greatly increased. The insulin/DNA values in the Nec-1 group, TNF-α group and blank control group were (13.21±3.15), (2.47±0.45), and (7.44±0.97) mIU/mg, respectively. Compared to the TNF-α group and the control group, the mRNA relative expression levels of insulin gene (6.73±1.07), glucagon gene (10.13±1.98), somatostatin gene (8.57±1.11) were significantly increased in the Nec-1 group (all <0.05), the rate of live cells (97.32±1.87)% and live B cells (90.86±3.68)% were increased significantly in the Nec-1 group (all <0.05).@*CONCLUSIONS@#TNF-α can induce neonatal porcine islet cells damage, which is attenuated in the presence of Nec-1. Nec-1 can increase the content of endocrine cells in NICCs.

A total of 108 kids with CVA in remission stage were divided into 18 groups using the random number table method, with 6 cases in each group. Changes in the cough score and fractional exhaled nitric oxide (FENO) level were observed after 15-day treatment. Results: The cough score and FENO level changed significantly in every group after treatment (all P<0.01). By the effect in improving cough score, the factors were listed as D, B, A, C and E in descending order; the most optimal manipulation parameter combination was group 17 (A3B2C1D3E1); the second optimal parameter combinations were group 7 (A3B1C2D1E3), group 13 (A2B1C2D3E1) and group 14 (A2B2C3D1E2). Regarding the effect in down-regulating the level of FENO, the factors were listed as C, A, E, B and D in descending order; the most optimal manipulation parameter combination was group 13 (A2B1C2D3E1); the second optimal parameter combinations were group 18 (A3B3C2D1E2), group 16 (A3B1C3D2E3) and group 14 (A2B2C3D1E2).Conclusion: Two most effective manipulation parameter combinations were selected out of 18 different parameter combinations in Liu's back tuina therapy for remission-stage CVA in kids. Doctors can choose an appropriate manipulation based on the symptom features of the disease.
ABSTRACT
Aquaporins (AQPs) are a class of membrane intrinsic proteins in medical helminthes that specifically mediate the transmembrane transport of water or other solute molecules. Previous studies have demonstrated that AQPs play a critical role in promoting the transmembrane transport of water, osmoregulation, uptake of nutrients, release of toxic metabolic products and transport of antiparasitic drugs, which may serve as promising vaccine candidates and drug targets for parasitic diseases. This review describes the structural characteristics of AQPs in medical helminthes, and discusses the feasibility of these AQPs as antihelminth vaccine candidates and drug targets, so as to provide insights into the development of novel vaccines and drugs against parasitic diseases.
ABSTRACT
Protein kinase A (PKA) is an important intracellular substance that regulates substance metabolism and biological functions, which exerts a wide range of biological effects through phosphorylation of specific serine/threonine residues in specific proteins. PKA plays an important role in the cAMP signaling pathway, and is involved in various life activities of parasites. Therefore, investigating the role of PKA in the life activities of parasites may provide insights into the development of novel anti-parasitic targets. The review mainly describes the structure and function of PKA and its role in life activities of parasites.

As the integration of human parasitology and medical microbiology curriculum, pathogen biology, although constructed and developed about 20-years, didn't realize the true integration of the two disciplines. Beyond that, it was also faced with numerous difficulties such severe compression of human par-asitology class, lack of teaching materials to achieve the true meaning of integration, difficulty to cultivate teachers and so on. The organ-system based learning (OBL) curriculum model may provide new strategies for the dilemma, to be resolved through the following channels: Rearranging the curriculum and teaching materials based on the classification of pathogenic organism parasitic or invasive organs; Corresponding training in microbiology and parasitology teaching by teachers continuous realization, while highlighting the professional teaching level of highly qualified teachers in both courses.
ABSTRACT
Objective To investigate the role of cervical spine finite element model in predicting the risk of cervical ligament injury during Sanda combat (Chinese boxing),and compare the differences in mechanical responses of cervical ligaments after hit by Baiquan (hook boxing) or by Straight punches (cross boxing).Methods After 3D reconstruction of head-neck osseous structure by using Mimics software based on CT images,an accurate headneck finite element model was developed with HyperMesh software.The moment-ROM (range of motion) of the model and the head acceleration after punching were validated.Then differences in ligament stress and distribution were compared between Baiquan and Straight punches under different punching forces (2.60,3.30,4.35kN).Results The established head-neck model was validated to have good biofidelity,and the predicted values of head linear acceleration and rotational acceleration after punching were in agreement with those reported in the literatures.As the punching force increased from 2.6 kN to 4.35 kN,the maximum stress in cervical ligament was 207,265,263 N for Baiquan,and 96.8,91.4 and 101.4 N for Straight punch,which was located at atlantoaxial ligaments.Under the same force level,Baiquan generated greater force than that by Straight punch for cervical ligament.Conclusions Compared with Straight punch,cervical ligament injuries are more likely to occur by Baiquan during Sanda combat,and the established finite element neck-head model can be used to study biomechanical mechanism of Sanda-induced injuries,and provide more accurate references for Sanda training and injury prevention.
ABSTRACT
Objective To observe the effect of somatostatin combined with transcatheter arterial infusion chemotherapy in the treatment of malignant intestinal obstruction.Methods 60 patients with malignant intestinal obstruction were enrolled in our hospital from January 2013 to June 2015.The rats were randomly divided into 4 groups: the conventional group(n=15),the growth inhibition group(n=15),the low dose intra-arterial infusion chemotherapy group(n=15)and somatostatin plus low-dose intra-arterial infusion chemotherapy group(n=15).The clinical symptom remission time,duration of clinical symptom remission and survival time were compared between the four groups.Results The study showed that somatostatin group of gastrointestinal decompression and symptom remission time were significantly better than the conventional group.Especially the symptom remission time is significantly faster than the conventional group and chemotherapy group(P< 0.05); the duration of chemotherapy group and somatostatin+artery perfusion chemotherapy group in survival time and relieve symptoms,were significantly better than the conventional group and somatostatin group(P< 0.05).Conclusion Somatostatin is beneficial to reduce the amount of gastrointestinal decompression in the treatment of malignant intestinal obstruction.Celiac artery infusion chemotherapy can help to improve the maintenance time and prolong the survival time of patients with malignant obstruction.The combination of somatostatin and celiac artery infusion chemotherapy is beneficial to relieve the symptoms and prolong the time interval,and improve the survival time of patients.
