Objective To investigate the relationship between prothrombin fragment 1+2 (F1+2) and peripherally inserted central catheter (PICC) associated thrombosis in cervical cancer patients, and provide certain clinical basis of early prevention in peripherally inserted central catheter associated thrombosis in cervical cancer patients. Methods One hundred and forty cervical patients with PICC were enrolled in this study, and they were divided into thrombosis group (35 patients) and non-thrombosis group (105 patients). The level of F1+2 was examined using enzyme-linked immunoassay, and was analyzed according to the clinic features. Results The level of F1+2 was correlated with clinical stage (r = 0.640, P = 0.004);but was not correlated with age, type of tumor and concurrent radiochemotherapy (P>0.05). The level of F1+2 in thrombosis group was (520.343 ± 121.759) pmol/L, in non- thrombosis group was (388.361 ± 104.873) pmol/L, and there was significant difference (P =0.001). The multi-factors Logistic analysis showed that the level of F1+2 (OR=1.011, P=0.001) and age (OR = 21.025, P = 0.031) were independent risk factors for the PICC associated with thrombosis in cervical cancer. Conclusions The level of F1+2 is closely related with clinical stage and PICC associated thrombosis, and it is an independent risk factor for the PICC associated with thrombosis in cervical cancer.

Objective To investigate the difference of expression and distribution of Toll-like receptor 4 (TLR4)between acquired immunodeficiency syndrome (AIDS)-related Kaposi sarcoma (AIDS-KS)and classic Kaposi sarcoma (KS).Methods The subjects were collected from The First Teaching Hospital of Xinjiang Medical University from January 2010 to January 2012,including 11 patients with AIDS-KS,7 patients with classic KS,7 human immunodeficiency virus (HIV)infective patients without KS and 7 healthy volunteers.Clinical data and biopsy specimens were collected.The expression of TLR4 was detected by immunohistochemical method.Statistical analysis of mean between two groups was conducted by using t test.Statistical analysis of ranked data was conducted by using U test.Comparison between groups was analyzed with one-way ANOVA.Results The expressions of TLR4 were both strongly positive in patients with AIDS-KS and classic KS,and mainly in alien vascular endothelial cells (VEC)and tumor cells.TLR4 was located on cell membrane and cytoplasm,and also in the nucleus. TLR4 was rarely expressed in the skin tissue in HIV infective patients without KS and healthy volunteers. The expressions of TLR4 in AIDS-KS,classic KS,HIV infective patients and healthy volunteers were 0.242±0.443,0.208±0.059,0.072±0.042 and 0.065 ±0.031 ,respectively (F =33.70,P <0.01 ). The expressions of TLR4 were lower in HIV infective (AIDS ) patients without KS and healthy volunteers.The expression level of TLR4 was significantly higher in KS patients compared with non-KS patients (t=4.097,P =0.003).However,TLR4 expression had no significant difference between AIDS-KS and classic KS patients (t =0.480,P =0.638).The expression of TLR4 was significantly higher in AIDS-KS patients compared with HIV infective patients (t=2.900,P =0.010).Conclusions The study identifies that TLR4 is highly expressed in patients with AIDS-KS or classic KS.It is suggested that TLR4 may play an important role in occurrence and development of KS.

Objective To explore the composition principles of prescriptions for simple obesity based on the analysis of medical literature issued in recently 30 years about Chinese medicine for simple obesity. Methods We collected literature of Chinese medicine in treating simple obesity from VIP, CNKI, Wanfang, CBM and CMCC/CMCI databases, and screened out the formulas for simple obesity to establish a formula database. And then the medication rules were figured out with the Traditional Chinese medicine Inheritance Support System version 2.5 (TCMISS 2.5) software. Results A total of 57 formulas were screened out. And the top 10 herbs with highest occurrence frequency in the prescriptions were Poria, Rhizoma Atractylodis Macrocephalae, Rhizoma Alismatis, Radix et Rhizoma Rhei, Fructus Crataegi, Radix Astragali, Radix Glycyrrhizae, Folium Nelumbinis, Pericarpium Citri Reticulatae and Semen Cassiae. After data mining, we got 13 high-frequency herb-pair combinations and 31 core combinations, and 8 new prescriptions were extracted. Conclusion The research has achieved the quantitative description of the relationship between the Chinese medicines, the extraction of the core combinations and the discovery of new Chinese medicine prescriptions for simple obesity. The results will provide references for the development of new Chinese medicines for the treatment of simple obesity .

Objective:To explore the current status and influencing factors of polypharmacy burden in inpatient with elderly comorbidity.Methods:Convenience sampling method was used to select 393 in patients with elderly comorbidity of multiple medications who were hospitalized in North China University of Science and Technology Affiliated Hospital from September 2020 to January 2021 as the research object, using the general situation questionnaire, the Living with Medicines Questionnaire (LMQ), the Perceived Social Support Scale (PSSS), the Medication Compliance Scale (Morisky Scale) to investigate. Descriptive analysis of general data characteristics and polypharmacy burden scores were performed, and t-test, variance analysis, and multiple linear stepwise regression analysis were used to analyze influencing factors. Results:The polypharmacy burden for inpatient with elderly comorbidity was (136.95 ± 22.34) points, and the score rate was 70.23%, which was at a moderately high level. Multi-factor analysis showed that age, education level, personal monthly income, the number of illnesses, the number of medications, the duration of medication, social support, and medication compliance were independent factors influencing polypharmacy burden in inpatient with elderly comorbidity ( R 2=0.821, adjusted R 2=0.818, F=220.65, P<0.001). Conclusions:The polypharmacy burden in inpatient with elderly comorbidity is at a moderately high level. It is recommended that medical staff should develop individualized nursing interventions to reduce the polypharmacy burden for the factors that affect the burden of multiple medications for this population.
