ABSTRACT
Objective:To study the medication rules of treating cervical spondylosis by National TCM master Liu Bailing based on data mining and network pharmacology, and explore the potential action mechanism of its core compounds.Methods:By collecting the prescriptions of National TCM master Liu Bailing treating cervical spondylosis in the past 8 years, this paper analyses the frequency, nature, flavor, meridian, hierarchical clustering and association rules of those prescriptions by RStudio to obtain the core prescription. Then, the effective components of the core prescription were collected by using TCMSP, and the network of "medicine-component-target" was constructed by using Cytoscape 3.8.0; by searching for databases like GEO, DisGeNET, TTD HPO and Genecards were retrieved to obtain the target data set of cervical spondylosis; by using STRING 11.0 platform to construct protein interaction network; by using DAVID platform to cary out gene ontology (GO) and KEGG pathway enrichment analysis; by using Auto Dock software for molecular docking.Results:In the 844 prescriptions, there are 199 Chinese medicines and the properties are mainly warm, plain and cold; the flavors were mainly sweet, pungent and bitter; mainly belong to the liver, spleen, and kidney meridians. The Association Rule shows that the core compound is made up of Salvia miltiorrhiza, Gastrodia elata, Rhizoma corydalis, Alisma rhizoma, centipede, Astragalus membranaceus and Rhizome of Pueraria. Besides, 140 effective constituents and 247 targets of the core prescription were screened, and the main constituents were quercetin, kamanol, luteolin, tanshinone ⅡA, β-sitosterol, etc. 13 core targets among the core prescription treating cervical spondylosis were obtained, which were enriched into 30 pathways including toll-like receptor signaling pathway, TNF signaling pathway and HIF-1 signaling pathway. Conclusion:National TCM master Liu Bailing treatment of cervical spondylosis mainly focuses on expelling wind and relieving pain, dredging meridians and soothing tendons, and the mechanism of action of the core prescription may focus on inhibiting inflammatory response and relieving oxidative stress, providing guidance and reference for the clinical treatment of cervical spondylosis.
ABSTRACT
Objective@#To investigate the efficacy and adverse reactions of palonosetron and dexamethasone in preventing cisplatin-induced nausea and vomiting.@*Methods@#From September 2015 to August 2017, a total of 217 nasopharyngeal carcinoma patients in the 163rd Hospital of PLA were randomly divided into two groups according to the digital table.The control group (n=108) was given palonosetron when used cisplatin treatment, the study group(n=109) was given palonosetron combined with dexamethasone.The clinical efficacy and adverse reactions in the two groups were observed.@*Results@#After treatment of 1-6 weeks, the incidence rates of headache, dizziness and fatigue in the study group were 7.2%, 2.9% and 3.4% respectively, which were significantly lower than those in the control group(12.7%, 6.0% and 6.3%), the differences between the two groups were statistically significant(χ2=10.902, 7.412, 6.207, all P<0.05). The prevention rate of nausea and vomiting in the control group was 75.5%, which in the study group was 80.9%, and at delay period, the prevention rate of nausea and vomiting in the control group was 85.5%, which in the study group was 91.0%, the differences between the two groups were statistically significant(χ2=5.615, 9.442, all P<0.05).@*Conclusion@#Palonosetron and dexamethasone are effective in the treatment of nasopharyngeal carcinoma with cisplatin-induced nausea and vomiting, and can reduce the side effects of palonosetron.
ABSTRACT
Objective To observe the efficacy and adverse reactions of ubenimex combined with radiotherapy for the treatment of early nasopharyngeal carcinoma. Methods A total of 129 patients with early nasopharyngeal carcinoma who were admitted to the 163th Hospital of PLA, the Second Affiliated Hospital of Hunan Normal University from October 2013 to September 2016 were retrospectively analyzed. Three-dimensional conformal radiotherapy was used in the control group and ubenimex combined with three-dimensional conformal radiotherapy was taken in the study group. Radiation injury response, quality of life and therapeutic effects of patients in both groups were observed respectively. Results The fatigue incidence of the study group was lower than that of the control group (57.8 % vs. 75.4 %, χ2= 4.481, P= 0.034). Karnofsky score (χ2=6.345, P=0.042; χ2=6.382, P=0.041, respectively) and weight change (χ2=6.014, P= 0.049; χ2= 6.351, P= 0.042, respectively) had statistical differences in both groups in the end of radiotherapy and 3 months after radiotherapy. 1-year non-distant metastasis survival rate (92.2 %, 59/64) in the study group was significantly higher than that in the control group (80.0 %, 52/65) (χ2=3.989, P=0.046). Conclusion Ubenimex combined with radiotherapy for early nasopharyngeal carcinoma can improve the patients' quality of life, reduce the radiation injury response and increase the metastasis-free survival rate.
ABSTRACT
Objective To prepare cysteamine group substitutes of catechin compounds from Weimaining. Methods After thiolased by cysteamine, Weimaining was subjected to the open column chromatography on C18, and subsequently to the semi-preparative high performance liquid chromatograph (HPLC) to prepare the cysteamine group substitutes of catechin compounds. Results Compounds 4β-(2-aminoethylthio)catechin, 4β-(2-aminoethylthio)epicatechin, and 4β-(2-aminoethylthio) epicatechin-3-O-gallate were obtained, and their purities were above 95%. Conclusion The method is simple and easy, and provides a reference for the preparation of the cysteamine group substitutes of catechin compounds.
ABSTRACT
ObjectiveTo study the expression level of HER-2 gene in the same pathological stage gastric cancer,and discuss the feasibility of HER-2 gene being the prognostic indicator.MethodsThe expression of HER-2 in gastric cancer was detected by immunohistocehmical technique and analyzed in relation with the pathological stage and prognosis of the patients.ResultsThe total positive rate of HER-2 in gastric cancer was 33.64％ (37/110).In stage Ⅱ,the weakly and strongly positive rates of gastric cancer were 21.31％ ( 13/61 ) and 9.84％ (6/61).In stage Ⅲ,the weakly and strongly positive rates of gastric cancer were 20.41％ (10/49) and 16.33％ (8/49).In the same pathological stage,the survival rate of patients with negative HER-2 expression was higher than weakly positive ones.And the survival rate of patients with strongly positive HER-2 expression was the lowest.The difference had statistical significance (P ＜ 0.01).ConclusionThe prognosis of patients in the same stage was correlated with the expression level of HER-2,which can be used to evaluate the biological behavior and prognosis of gastric cancer.
ABSTRACT
Objective To investigate the feasibility of application of anterograde tubular ileal fistula in Ⅰ stage anastomosis of colon cancer with acute obstruction. Method Eighty patients of colon cancer with acute obstruction who treated with anterograde tubular ileal fistula in Ⅰ stage anastomosis were analyzed restropectively. Result Clinical observation showed that 80 patients were cured and discharged,no one did occur anastomotic leakage, abdominal abscess,and other serious complications. Conclusion If correctly graspe the timing of operation for colon cancer with acute obstruction,irrigation methods,good perioperative management,select the anterograde tubular ileal fistula, Ⅰ stage resection and anastomosis is safe and feasible.
ABSTRACT
Impaired wound healing in diabetes is a significant clinical problem which is thought to be associated with neuropathy and angiopathy previously . The present study indicates that accumulation of glucose and glycometabolic products in skin tissue, as the result of glycometabolic disorders, which contributes to cutaneous environmental alterations in diabetes mellitus, and subsequently induces the abnormal cell behaviors, cytokine alteration and matrix modification. Thus, diabetic neuropathy and angiopathy might be regarded as the pathological outcome of cutaneous environmental alterations. In conclusion, glycometabolism disorders could be described as one of the initial events for the alteration involving in the underlying cutaneous disorder which impair healing process. The related research focuses on the initial event of controlling disorders in wound healing and therefore contribute to providing the strategy of treatment as based on these approaches.
