The distribution of blood pressure and associated factors of the elderly with type 2 diabetes in Jiangsu Province / 中华预防医学杂志

Objective: To investigate the distribution of blood pressure and analyze the associated factors of blood pressure of the elderly with type 2 diabetes in Jiangsu Province. Methods: The elderly over 60 years old participants with type 2 diabetes in the communities of Huai'an City and Changshu City, Jiangsu Province were selected in this study. They were divided into two groups: taking antihypertensive drugs and not taking antihypertensive drugs. The demographic characteristics, such as age and sex, and relevant factors were collected by questionnaire. The systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by physical examination. The percentile of SBP and DBP in each age group of men and women were described. The kernel density estimation curve was used to show the blood pressure distribution. The trend of blood pressure with age was fitted by locally weighted regression. The logistic regression model was used to analyze relevant factors of blood pressure. Results: A total of 12 949 participants were included in this study, including 7 775 patients in the antihypertensive drug group and 5 174 patients in the group without antihypertensive drugs. The SBP of participants was concentrated at 140-160 mmHg, and their DBP was concentrated at 75-85 mmHg. There were significant differences in the distribution of blood pressure among the subgroups of body mass index (BMI) and rural areas whether taking antihypertensive drugs and not. For participants aged under 80 years old, the SBP showed an increasing trend with age and the DBP showed a decreasing trend with age. Age, BMI ≥24 kg/m2, fasting blood glucose ≥7.0 mmol/L, living in rural areas and no smoking were influencing factors of the elevated SBP; BMI ≥24 kg/m2, male, living in rural areas, no smoking, drinking alcohol and not receiving drug hypoglycemic treatment were influencing factors of the elevated DBP. Conclusion: The SBP of older diabetic adults in Jiangsu Province is at a high level, and the distribution of blood pressure is significantly different between men and women in taking antihypertensive drugs group. The SBP presents a rising trend and the DBP is decreasing at the age of 60-80 years. The blood pressure level of this population are mainly affected by age, BMI, urban and rural areas, smoking.

Inokosterone Is A Potential Drug Target of Estrogen Receptor 1 in Rheumatoid Arthritis Patients: Analysis from Active Ingredient of Cyathula Officinalis / 中国结合医学杂志

OBJECTIVE@#To elucidate the active compounds and the molecular mechanism of Cyathula Officinalis as a drug treatment for rheumatoid arthritis (RA).@*METHODS@#The target genes of active ingredients from Cyathula Officinalis were obtained from bioinformatics analysis tool for the molecular mechanism of traditional Chinese medicine. The protein-protein interaction between the target genes were analyzed using STRING and Genemania. The transcriptome of RA patients compared to healthy people (GSE121894) were analyzed using R program package Limma. The relative expression of the target genes was obtained from the RNA-seq datasets. The molecular docking analyses were processed based on the molecular model of estrogen receptor 1 (ESR1) binding with estradiol (PDB ID:1A52). The binding details were analyzed by SYBYL.@*RESULTS@#Inokosterone, ecdysterone, and cyaterone were the 3 active ingredients from Cyathula Officinalis that bind to target genes. Of all the significantly changed genes from RA patients, ESR1, ADORA1, and ANXA1 were significantly increased in mRNA samples of RA patients.@*CONCLUSION@#ESR1, the transcription factor that binds inokosterone in the molecular binding analysis, is the target protein of Cyathula Officinalis.

Nimotuzumab plus chemotherapy with docetaxel, cisplatin, 5-fluorouracil for locally advanced head and neck squamous cell carcinoma: A clinical study

Background: A clinical study was conducted to determine the efficacy of nimotuzumab combined with docetaxel, cisplatin, and 5-fluorouracil (TPF) for patients with locally advanced head and neck squamous cell carcinoma (HNSCC) after surgery and conformal radiotherapy. Methods: Thirty-one HNSCC patients received three courses of chemotherapy every 21 days, at a dose of 75 mg/m2 of docetaxel and cisplatin on day 1 and 750 mg/m2 of 5-fluorouracil on days 1–5 followed by 200 mg/m2/week of nimotuzumab on week 1–2 (day 6–21). Results: After sequential therapy, complete and partial responses were observed in 10 (32.3%) and 17 (54.8%) patients, respectively. The overall response rate was 87.1%. A progression-free survival of 71.2% (95% confidence interval [CI] 51.6%–93.7%) and an overall survival of 78.3% (95% CI 58.9%–89.5%) were achieved at 2nd year. The most common Grade 3–4 toxicities during the complete treatment were lymphopenia (25.8%), neutropenia (22.6%), anemia (12.9%), and diarrhea (16%). In addition, no rash and treatment-related death occurred during this study. Conclusions: Nimotuzumab in combination with TPF has been well tolerated as a treatment program for locally advanced HNSCC

Knockdown of ubiquitin-specific peptidase 39 inhibited the growth of osteosarcoma cells and induced apoptosis in vitro

BACKGROUND: Ubiquitin specific peptidase 39 (USP39), an essential factor in the assembly of the mature spliceosome complex, has an aberrant expression in several cancer. However, its function and the corresponding mechanism on human osteosarcoma has not been fully explored yet. METHODS: The mRNA and DNA copies of USP39 were increased in osteosarcoma cancer tissues compared with the one in human normal tissues according to datasets from the publicly available Oncomine database. A further western blot analysis also demonstrated an aberrant endogenous expression of USP39 in three different osteosarcoma cells. Then lentivirus-mediated short hairpin RNA (shRNA) was designed to silence USP39 in human osteosarcoma cell line U2OS, which is used to test the impact of USP39-silencing on cellular proliferation, colony formation, cell cycle distribution and apoptosis. RESULTS: Knockdown of USP39 expression in U2OS cell significantly decreased cell proliferation, impaired colony formation ability. A further analysis indicated suppression of USP39 arrested cell cycle progression at G2/M phase via p21 dependent way. In addition, the results of Annexin V/7-AAD staining suggested the knockdown of USP39 could promote U2OS cell apoptosis through PARP cleavage. CONCLUSIONS: These results uncover the critical role of USP39 in regulating cancer cell mitosis and indicate USP39 is critical for osteosarcoma tumorigenesis.
