ABSTRACT

Background: Xuebifang (XBF), a potent Chinese herbal formula, has been employed in managing diabetic peripheral neuropathy (DPN). Nevertheless, the precise mechanism of its action remains enigmatic. Purpose: The primary objective of this investigation is to employ a bioinformatics-driven approach combined with network pharmacology to comprehensively explore the therapeutic mechanism of XBF in the context of DPN. Study design and Methods: The active chemicals and their respective targets of XBF were sourced from the TCMSP and BATMAN databases. Differentially expressed genes (DEGs) related to DPN were obtained from the GEO database. The targets associated with DPN were compiled from the OMIM, GeneCards, and DrugBank databases. The analysis of GO, KEGG pathway enrichment, as well as immuno-infiltration analysis, was conducted using the R language. The investigation focused on the distribution of therapeutic targets of XBF within human organs or cells. Subsequently, molecular docking was employed to evaluate the interactions between potential targets and active compounds of XBF concerning the treatment of DPN. Results: The study successfully identified a total of 122 active compounds and 272 targets associated with XBF. 5 core targets of XBF for DPN were discovered by building PPI network. According to GO and KEGG pathway enrichment analysis, the mechanisms of XBF for DPN could be related to inflammation, immune regulation, and pivotal signalling pathways such as the TNF, TLR, CLR, and NOD-like receptor signalling pathways. These findings were further supported by immune infiltration analysis and localization of immune organs and cells. Moreover, the molecular docking simulations demonstrated a strong binding affinity between the active chemicals and the carefully selected targets. Conclusion: In summary, this study proposes a novel treatment model for XBF in DPN, and it also offers a new perspective for exploring the principles of traditional Chinese medicine (TCM) in the clinical management of DPN.

ABSTRACT

BACKGROUND: The pineal tumor was once considered as a restricted area for surgery. Such cases are rare, with many different opinions on surgical treatment. This study aimed to review our experience of tumor treatment in the pineal region and explore the optimal treatment strategy. METHODS: The clinical data of 72 patients with pineal tumors from January 1997 to May 2015 (18 years) were retrospectively analyzed. Preoperative preparation, pathology type, tumor resection rate, surgical approach, and follow-up outcomes were used as the indicators to evaluate the treatment efficacy. RESULTS: The Krause approach was used in 46 cases, the Poppen approach in 10 cases, and the transcallosal-lateral ventricle-choroid fissure approach in 16 cases. The postoperative pathological results were as follows: 24 cases of germinoma, 11 of teratoma, 15 of glioma, 6 of meningioma, 11 of Pineocytoma, 2 of cholesteatoma, 2 of cavernous hemangioma, and 1 of choriocarcinoma. Further, the study included 64 cases of total surgical resections, 8 of subtotal resections, and 2 deaths. The follow-up period was from 7 months to 10 years. Further, 51 (70.8%) patients were followed up. The multivariate regression model showed that the surgical method and the pathological type contributed significantly to predicting outcomes. CONCLUSIONS: The type of pathology, extent of excision, and surgical approach had a significant impact on the prognosis of patients. The transcallosal-lateral ventricle-choroid fissure approach for large and medium-sized pineal tumors near the posterior part of the third ventricle had good efficacy.

ABSTRACT

Metabolic diseases such as obesity, type 2 diabetes mellitus, and hyperlipidemia are associated with the dysfunction of gut microbiota. Traditional Chinese medicines (TCMs) have shown considerable effects in the treatment of metabolic disorders by regulating the gut microbiota. However, the underlying mechanisms are unclear. Studies have shown that TCMs significantly affect glucose and lipid metabolism by modulating the gut microbiota, particularly mucin-degrading bacteria, bacteria with anti-inflammatory properties, lipopolysaccharide- and short-chain fatty acid (SCFA)-producing bacteria, and bacteria with bile-salt hydrolase activity. In this review, we explored potential mechanisms by which TCM improved metabolic disorders via regulating gut microbiota composition and functional structure. In particular, we focused on the protection of the intestinal barrier function, modulation of metabolic endotoxemia and inflammatory responses, regulation of the effects of SCFAs, modulation of the gut-brain axis, and regulation of bile acid metabolism and tryptophan metabolism as therapeutic mechanisms of TCMs in metabolic diseases.

ABSTRACT

BACKGROUND: The abnormal expression of genes is an essential factor affecting the prognosis of cancer. RNA modification is a way of regulating post-transcriptional levels, including m6A, m5C, m1A RNA methylation. Studies have found that RNA methylation regulates tumorigenesis development and stem cell regeneration. However, there are few studies on lung adenocarcinoma. This study aims to explore the clinical value of RNA methylation for lung adenocarcinoma. METHODS: We summarized thirty-one RNA methylation regulators. The training set was obtained from The Cancer Genome Atlas (TCGA) database, and the test set was obtained from the Gene Expression Omnibus (GEO) database. The Wilcoxon test was used to analyze the expression of RNA methylation regulators. We constructed tumor subgroup models and risk models based on the expression of those regulators. Principal component analysis (PCA) and the receiver operating characteristic (ROC) confirmed the accuracy of the models. Real-time polymerase chain reaction (PCR) validates the results in vitro. RESULTS: Most RNA methylation regulators had distinct expressions in tumor tissues and adjacent tissues (P<0.05). All the models showed high predictive performance (AUC: 0.65-0.82), and the five-year survival of patients in each group was statistically different (P<0.05). The patients in the high-risk group were more likely to have a higher stage, more lymph node metastases, and distant metastases, showing a poor clinical outcome. Patients with high expression of NOP2 or HNRNP were more likely to have a poorly differentiated in vitro experiment. CONCLUSIONS: With our study, we found that the expressions of most RNA methylation regulators were significantly different in cancer and para-cancerous tissues. Different molecular phenotypes constructed by RNA methylation regulators can be independent risk factors for the prognosis of lung adenocarcinoma. Our study demonstrates the critical role of RNA methylation in lung adenocarcinoma, and it is expected to supply a reference for the prognostic stratification and treatment strategy development of lung adenocarcinoma.

ABSTRACT

Endoglin is an essential molecule during angiogenesis, vascular development, and integrity. Till now, many studies have investigated the association between endoglin polymorphisms and intracranial aneurysm (IA) risk, with the results remained inconclusive. Therefore, we performed a meta-analysis to summarize the possible association.We searched PubMed and Embase until June 2015 to identify studies addressing the association between endoglin polymorphisms and IA risk. The summary odds ratios (ORs) and their corresponding 95% confidence interval (CI) were calculated to assess the strength of the association.Eleven studies with a total of 1501 cases and 2012 controls were finally included in this meta-analysis, with 10 studies investigating endoglin 6-bp insertion (6bINS) polymorphism and 4 studies investigating 1800956 polymorphism. No significant association between endoglin 6bINS polymorphism and IA risk was detected in overall estimation (I/I vs wt/I + wt/wt: OR = 1.21, 95% CI = 0.87-1.69) or in the subgroup analysis by ethnicity, control source, or ruptured status. However, we observed an association with borderline significance of 6bINS with IA occurrence (I/I vs wt/I + wt/wt: OR = 1.49, 95% CI = 0.99-2.25, P = 0.058) in studies applying matched controls. Furthermore, we detected a significant association for 6bINS polymorphism of endoglin with increased risk of familial IA (I vs wt, OR = 1.64, 95% CI = 1.10-2.42) but not sporadic IA (I vs wt, OR = 1.09, 95% CI = 0.68-1.45). With regard to rs1800956, our pooled results indicated a significantly decreased IA risk in individuals carrying C allele (C/C vs G/C + G/G: OR = 0.65; 95% CI = 0.45-0.94).This meta-analysis provided no evidence for the association between 6bINS polymorphism with overall IA risk. However, we detected a significant association of 6bINS allele with increased risk of familial IA. Also, we found that rs1800956 was significantly related to IA occurrence. Further, well-designed studies with large sample size are warranted and updated meta-analysis is needed to verify our findings.

ABSTRACT

Purple lettuce was grown hydroponically under six different nitrogen nutrition conditions, with NO(3-)-N:NH(4+)-N at 1:0, 4:1 and 1:1 combined with nitrogen application levels of 10 and 15 mmol · L(-1), for 25 days in solar greenhouse, then treated with short-term continuous lighting (SCL) before harvest to study the changes in contents of nutrients and analyze the effects of nitrogen nutrition conditions on the changes. Results showed that the shoot dry mass of all six nitrogen nutrition conditions were significantly improved under SCL treatment, by 35.1% at least, and the root dry mass increased greatly except for NO(3-)-N:NH(4+)-N 1:1 combined with nitrogen application level 15 mmol · L(-1) treatment and NO(3-)-N:NH(4+)-N 1:0 combined with nitrogen application level 10 mmol · L(-1) treatment. The relative contents of total phenols and flavonoid of different nitrogen nutrition conditions turned significantly different after treatment with SCL. The relative contents of total phenols and flavonoid were enhanced with the improvement of ammonium nitrogen ratio, while the relative content of anthocyanin increased and then decreased with the improvement of ammonium nitrogen ratio. The lighting treatment reduced the nitrate content of leaf blade of all six nitrogen nutrition conditions remarkably by 23.2% at least. The contents of ascorbic acid, soluble sugar and soluble protein rose significantly under SCL treatments. The study showed that the reduction of nitrate content speeded up with the enhancement of nitrogen application level and ammonium nitrogen ratio, and the advancement of ascorbic acid content slowed down with the increasing nitrogen application level. The soluble sugar improvement speed increased with the increasing ammonium nitrogen ratio, and SCL lifted the dry mass of the lettuce greatly. The results showed that SCL with LED lamps improved significantly the dry matter of lettuce under different nitrogen nutrition conditions, reduced the nitrate content and increased the ascorbic acid, soluble sugar and soluble protein contents greatly. In addition, nitrogen nutrition conditions affected the effectiveness of short-term continuous lighting on quality improvement rate of hydroponic lettuce remarkably.

ABSTRACT

Phytochemicals in vegetables are important for human health, and their biosynthesis, metabolism and accumulation are affected by environmental factors. Light condition (light quality, light intensity and photoperiod) is one of the most important environmental variables in regulating vegetable growth, development and phytochemical accumulation, particularly for vegetables produced in controlled environments. With the development of light-emitting diode (LED) technology, the regulation of light environments has become increasingly feasible for the provision of ideal light quality, intensity and photoperiod for protected facilities. In this review, the effects of light quality regulation on phytochemical accumulation in vegetables produced in controlled environments are identified, highlighting the research progress and advantages of LED technology as a light environment regulation tool for modifying phytochemical accumulation in vegetables.

ABSTRACT

AIM: To assess the current clinical evidence of the effectiveness of Xiangshaliujunzi Decoction (XSLJZD) for the treatment of diabetic gastroparesis (DGP). METHODS: Randomized controlled trials (RCTs) were retrieved from seven major electronic databases including Medline, the Cochrane Library, Embase, Chinese Biomedical Literature Database (CBM), Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database (VIP), and Wanfang Databases, using search dates from the beginning of the databases to May 2013. No language limitations were applied. We included RCTs that used XSLJZD or a modified XSLJZD compared with a control group for the treatment of DGP. The control groups included conventional treatment (Western medicinal treatment), placebo, and no treatment (blank), but not acupuncture. The main outcome index was clinical effectiveness, which was based on the gastric emptying test and variations in the gastrointestinal (GI) symptoms between the treatment and control groups after intervention. Data extraction, analysis, and quality assessment were conducted according to the Cochrane Handbook for Systematic Review of Interventions, Version 5.1.0. RESULTS: Ten RCTs involving 867 patients (441 in the experimental groups, and 426 in the control groups) were identified, and the overall methodological quality was evaluated as generally low. In the treatment groups, all 10 trials used herbs alone as the treatment, whereas all control groups used prokinetic medicine. The period of intervention ranged from 2 to 8 wk. Three classes were used to evaluate treatment efficacy: significant effective, effective, and ineffective, and all trials used the clinical effective rate (based on the gastric emptying test and changes in GI symptoms) to evaluate efficacy. The data showed that the effects of XSLJZD for the treatment of DGP were superior to the control group (n = 867, RR =1.33, 95%CI: 1.24-1.42, Z = 8.11, P < 0.00001). Two trials recorded adverse events, and one trial reported follow-up. CONCLUSION: XSLJZD could restore the gastric emptying rate and improve symptoms. However, the evidence remains weak due to the poor methodological quality of the included studies.

ABSTRACT

Diabetic peripheral neuropathy is a common chronic complication of diabetes. Routine clinical management uses analgesics to relieve pain in combination with drugs for nerve repair. The drugs are often not effective for the severe pain cases, and these western medications also have side effects. We report a more effective treatment of diabetic peripheral neuropathic pain using a high dose of a traditional Chinese medicine, aconitum (including both Radix aconite preparata and Radix aconite kusnezoffii), in combination with Huangqi Guizhi Wuwu Tang (i.e., astragalus, cassia twig, white peony root, and spatholobi). In order to achieve stronger analgesic effects, we increased the clinical dosage of aconitum from 15 to 120 g. The aconitum was boiled for 6-8 hours, and licorice was also used to reduce potential toxicities of aconitum. In the four reported cases, the patients' neuropathic pain was remarkably reduced and the EMG profile was also improved with this treatment regimen. Adverse reactions were not observed during the therapy. Thus, aconitum represents a promising and safe treatment for the well-being of patients and their diabetic peripheral neuropathic pain. Future controlled clinical trials using traditional Chinese medicines containing aconitum in treating the neuropathic pain are warranted.

ABSTRACT

Diabetic nephropathy is a leading cause of chronic renal failure. Recently, Euonymus alatus showed therapeutic potential in the treatment of diabetes and its chronic complications. In this study, effects of Euonymus alatus and its mechanism in the treatment of diabetic nephropathy were investigated. Diabetic nephropathy was induced in Sprague-Dawley rats by uninephrectomy plus streptozotocin (STZ) administration. Euonymus alatus and irbesartan, as a positive control, were lavaged to these rats for 12 weeks. Our data showed that Euonymus alatus was efficient in lowering HbA1c, improving blood lipids, decreasing 24 h urine protein and protecting kidney function. Pathological studies found kidney damage, including extracellular matrix expansion and glomerulosclerosis, were improved by Euonymus alatus treatment. Further investigation found that the herb had a role in downregulating the expression of transform growth factor ß(1). In conclusion, Euonymus alatus has a protective role in diabetic nephropathy, which may be related to its downregulation of transform growth factor ß(1) expression.

ABSTRACT

OBJECTIVE: To investigate the influence of trauma on the tumorigenicity of rat glial tumor stem cells (C6-side population cell, C6-SP) in vivo. METHODS: Rat glial tumor stem cells C6-SP were isolated by flowcytometry. The biological behavior of C6-SP cells were observed by means of MTT experiment, single cell cloning, and cell cycle study with FCM CD133 expression was measured by immunofluorescence and FCM.. The tumorigenicity of C6-SP cells in vivo was evaluated by in situ tumor growth after intracranial implantation. The rat model was established by intracranial implantation of C6-SP cells. 10 days later, the rats in experimental groups were subjected to orthotopic or ectopic trauma. 24 days later, brain specimen was retrieved, gross tumor volume was measured, and Ki67 was evaluated by immunochemistry. The migration of stem cell was studied by the method to observe the relocation of C6-SP cells. RESULTS: Clustrus tumor growth was seen when C6-SP cell was cultured in serum-free medium. The doubling time of C6-SP cell was shorter than ordinary C6 cell. Single stem cell cloning efficiency of C6-SP cell was 77% whereas that of ordinary C6 cell was 16.4%. Among cloned C6-SP cell and ordinary C6 cell, 49.7% +/- 5.2% and 35.2 +/- 4.3% were at G0/G1 phase respectively. CD133 expression of C6-SP cells was positively shown by immunofluorescence. Tumorigenesis was 100% 2 weeks after in situ implantation of C6-SP cells. Gross tumor volume and Ki67 expression of orthotopic trauma group were larger and higher than those of ectopic trauma group or blank control group (P < 0.05) whereas difference was insignificant in the later two groups (P > 0.05). Red stained cells relocation was seen in both traumatized groups and absent in controls. CONCLUSION: C6-SP cells are the tumor stem cells (TSCs) for rat glioma. Trauma at the lesional site could increase tumorigenicity of the C6-SP cells. Moreover, trauma could induce migration of C6-SP cells in brain.

ABSTRACT

In this study, we investigated the effects of a Chinese herbal medicine formula xiao-gao-jiang-zhuo (XGJZ) in obese rats induced by a high-fat diet. Ten male rats in the normal group were fed with a standard diet. Another 50 male obese rats were induced by a 12-week high-fat diet feeding, and were randomly divided into five groups (n = 10 per group): the model group, the high-dose XGJZ group, the middle-dose XGJZ group, the low-dose XGJZ group, and the sibutramine group. After 14 weeks of treatment, body weight, abdominal fat, blood lipid and serum insulin level were measured, and the protein and gene expression of PTP1B in liver tissue was tested. Our data showed that the body weight of the high-dose and middle-dose groups and the sibutramine group had significant differences in comparison with the model group (p < 0.05), and all three dose groups had significantly reduced abdominal fat (p < 0.05). The triglyceride level of the three dose groups and the sibutramine group, and the total cholesterol level of the middle-dose group were all significantly reduced (p < 0.05). The serum insulin of the high-dose and middle-dose groups also decreased significantly (p < 0.05). The expression of hepatic PTP1B mRNA of the three dose groups decreased significantly in comparison with the model group (p < 0.05 or 0.01). The expression of hepatic PTP1B protein of the high-dose and middle-dose groups decreased significantly (p < 0.05). Our data suggested that XGJZ can modulate the body weight, abdominal fat and blood lipid in the obese rats, and this modulation might improve insulin resistance by inhibiting the PTP1B signal pathway.

ABSTRACT

The Chinese formula Tang-Min-Ling (TML), an improved product of the decoction of Dachaihu which has a history of more than 2000 years, has main constituents of Coptis chinensis Franch, Scutellaria baicalensis Georgi, Rheum officinale Baill and Bupleurum chinense DC. A multi-central randomized controlled investigation performed previously by us has showed that TML has positive effects on regulating glycometabolism in type 2 diabetes (T2DM) patients, but the mechanisms remain unclear. Using Otsuka Long-Evans Tokushima Fatty (OLETF) rats as an animal model with rosiglitazone as a positive control, we were able to detect TML's effect on the serum glucose, serum lipid, serum leptin and adiponcetin after oral administration for 12 weeks. We were also able to detect the insulin resistance level by a glucose clamp test and study the mechanisms of TML in improving insulin resistance by detecting skeletal muscle AMP-activated protein kinase (AMPK) and glucose transporter 4 (GLUT4). Results showed that TML significantly reduced the glucose area under a curve of the oral glucose tolerance test, and had a positive effect in regulating serum lipid metabolism. TML treatment also significantly reduced the serum leptin level, but it had no effect on the serum adiponectin level. The AMPK enzymatic activity and GLUT4 expression in Skeletal Muscle were also upregulated in the TML group. The results suggest that the Chinese medicine TML, which contains Coptis chinensis Franch as one of its components, improves glycometabolism and its possible mechanisms may involve in improvement of insulin resistance of OLETF rats.

ABSTRACT

Intracranial clear-cell meningioma (CCM) is rarely reported in the literature since it has to be distinguished from other subtypes of meningioma. Most of the CCMs are intraspinal, according to the related literature. We report a case of occipital parietal CCM in a 6-year-old child, review all the 35 intracranial CCMs that have been reported since 1995 to present and discuss their clinical, radiological and histopathologic characteristics.

ABSTRACT

PURPOSE: We report a case of head and neck inflammatory myofibroblastic tumor (IMT) in an infant. Reviewing the literature, we discuss the etiology, diagnosis, treatment, and prognosis of the head and neck IMT in children. MATERIALS AND METHODS: A 52-day-old infant was admitted with an enlarging lesion in the right head and neck region. Following total excision, the lesion recurred and progressed to terminal stage. We performed a review of the literature on head and neck IMTs in children up to the age of 18 years and assessed the treatments and related prognosis of IMT in the head and neck region. RESULTS AND CONCLUSIONS: The children's prognosis of head and neck IMT is diverse with different treatments. Combined treatment of surgical and corticosteroid is recommended for younger children, especially infants.

ABSTRACT

OBJECTIVE: To observe the expression levels of BDNF and bFGF, the variation of superoxide dismutase (SOD) and malondialdehyde (MDA) in serum and injury neuron of rat, and to evaluate the effect of Tetramethylpyrazine (TMP) on neuro-protection finally. METHODS: 120 SD rats were randomly assigned into three groups: pseudo-operation group, severe brain injury model group and TMP treatment group. Every group contained 40 rats. The severe brain injury (SBI) of rat was established according to Feeney' s method. The treatment group was administrated with TMP transperitoneally. Rats were killed at 7 h, 24 h, 72 h, 168 h respectively after SBI. BDNF, bFGF, Nissl body and neurofunction were detected in every group at all the time scales. MDA and SOD of serum were also detected by radical immunoassay. RESULTS: After rat SBI treated with the administration of TMP, the expression of BDNF and bFGF increased significantly in the injured brain tissue (P<0.05), and the MDA level showed to be decreased but the SOD was increased in serum (P<0.05). The Nissl body and neuro-function were well protected. CONCLUSION: TMP may protect the rat cerebral neurons from SBI.

ABSTRACT

OBJECTIVE: To observe the variation of endothelin (ET) and nitric oxide (NO) in plasma and cerebrospinal fluid (CSF) in rabbits, and evaluate the effects of tetramethylpyrazine (TMP) on the prevention and cure of cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH). METHODS: 24 New Zealand rabbits were randomly assigned into three groups: contrast group, experiment group and blank group. Every group contained 8 rabbits. SAH was established according to inject blood into the cisterna magna. The experiment group was administrated with TMP (20 mg/kg x d) transperitoneally. ET and NO of plasma and CSF were detected by radical immunoassay at 72 h and 168 h after SAH. Neurofunction were detected in every group at all the time scales. RESULTS: (1) After SAH, the level of ET in CSF increased significantly in contrast group compared with that in experiment and blank groups (P<0.05). The value of ET at 168 h was higher than that at 72 h. The level of ET in plasma increased significantly in contrast group compared with blank and experiment groups (P<0.05), and no significant contrast could be found between blank and experiment group. (2) After SAH, the value of NO in CSF was lower in contrast group than in other groups (P<0.05), and the level of NO in CSF continued to decrease in all groups on some extent. As time went by, no significant contrast could be found in all groups. The value of NO in plasma was lower in contrast group than in other groups (P<0.05). There was no significant difference between experiment and blank groups. (3) The neuro-function score continued to be increased in contrast group, but decreased in experiment one. The neuro-function score was lower in experiment group than in contrast one at every time point (P<0.05). CONCLUSION: After administration of TMP, the variation of ET has the continued decrease in plasma and CSF; the variation of NO shows the continued increase in plasma and CSF; neurological function gets possibly protected. TMP may prevent from and cure CVS after SAH.
