OBJECTIVETo explore seroepidemiological status and vaccine coverage of hepatitis B among drug users in Xi'an.

METHODS545 drug users in the Xi'an Compulsory Detoxification Center were asked to answer questionnaire and provide blood sample (3-5 ml) for test of HBsAg, anti-HBc and anti-HBs from March to June 2013. Totally, 545 subjects were surveyed and tested. All of them effectively completed the survey.

RESULTSThe positive rates of HBsAg, anti-HBc and anti-HBs were 29.4% (160/545), 60.0% (327/545) and 56.1% (306/545), respectively. Eighty five subjects (15.6%) were negative for all of the three markers. The prevalence of HBsAg and anti-HBc among injection drug users were 40.0% (94/235) and 65.6% (154/235), which was significantly higher than non- injection drug users' (21.6% (52/241), 58.5% (141/241)) and mixed non-injection and injection drug users ((20.3% (14/69), 46.4% (32/69)) (χ(2) = 23.518 and 9.017, respectively, P < 0.05) . The HBsAg positive rate (30.6% (153/500)) of subjects with more than once per day of drug using within one year was significantly higher than those who used drugs for 2-3 times per week (15.6% (7/45)) (χ(2) = 4.51, P < 0.05). Only 11.7% (64/545) of drug users had a clear history of hepatitis B vaccination. The vaccination rate of subjects (3.5% (5/141)) with primary education or below was significantly lower than those with high school (16.3% (45/276)) (χ(2) = 26.61, P < 0.05). The vaccination rate of subjects (7.8% (12/153)) over 45 years old was significantly lower than that of subjects below 30 years old (15.9% (21/132)) and 30-44 years old (11.9% (31/260)) (χ(2) = 30.36, P < 0.05). The vaccinees had a significantly higher positive rate of anti-HBs (73.4% (47/64)) than those who without vaccination (53.8% (259/481)) (χ(2) = 8.81, P = 0.003), but the positive rates of HBsAg (16.7% (11/64)) were lower than those who without vaccination (31.0% (149/481)) (χ(2) = 23.52 and 9.02, respectively;P > 0.05).

CONCLUSIONThe HBV infection status among drug users in Xi'an was in serious condition, while a low vaccination rate was also discovered among them.

There are some risks in the clinical drug use due to limited clinical data and effective pharmacodynamic monitoring methods. By reviewing the relevant literature at home and abroad ，this paper summarizes the research progress of in vivo pharmacokinetics and toxicity of NVB ，fully understands the pharmacokinetic characteristics and influencing factors of NVB ，the influencing factors of toxicity ，and the application status of pharmacokinetics in the adjustment of administration scheme ，so as to provide reference for its clinical rational use.

OBJECTIVEThis study is aimed at observing the role of long noncoding RNAs (lncRNAs) in the pathogenesis of abdominal aortic aneurysm (AAA).

METHODSLncRNA and mRNA expression signatures of AAA tissues and normal abdominal aortic tissues (NT) were analyzed by microarray and further verified by Real-time quantitative reverse-transcription PCR (qRT-PCR). The lncRNAs-mRNAs targeting relationships were identified using computational analysis. The effect of lnc-ARG on 5-lipoxygenase (ALOX5) expression was tested in HeLa cells.

RESULTSDifferential expressions of 3,688 lncRNAs and 3,007 mRNAs were identified between AAA and NT tissues. Moreover, 1,284 differentially expressed long intergenic noncoding RNAs and 206 differentially expressed enhancer-like lncRNAs adjacent to protein-coding genes were discerned by bioinformatics analysis. Some differentially expressed lncRNAs and mRNAs between AAA and normal tissue samples were further verified using qRT-PCR. A co-expression network of coding and noncoding genes was constructed based on the correlation analysis between the differentially expressed lncRNAs and mRNAs. In addition, the lnc-ARG located within the upstream of ALOX5 was sorted as a noncoding transcript by analyzing the protein-coding potential using computational analysis. Furthermore, we found that lnc-ARG can decrease the mRNA level of ALOX5 and reactive oxygen species production in HeLa cells.

CONCLUSIONThis study revealed new lncRNA candidates are related to the pathogenesis of AAA.

Objective: To analyze the current adherence to imatinib in patients with gastrointestinal stromal tumors (GIST) in China and its influencing factors. Methods: A cross-sectional survey was conducted. Study period: from October 1, 2020 to November 31, 2020. Study subjects: GIST patients taking imatinib who were diagnosed and treated in public tertiary level A general hospitals or oncology hospitals; those who had not been pathologically diagnosed, those who never received imatinib, or those who had taken imatinib in the past but stopped afterwards were excluded. The Questionnaire Star online surgery platform was used to design a questionnaire about the adherence to adjuvant imatinib therapy of Chinese GIST patients. The link of questionnaire was sent through WeChat. The questionnaire contained basic information of patients, medication status and Morisky Medication Adherence Scale. Results: A total of 2162 questionnaires from 31 provinces, autonomous regions, and municipalities were collected, of which 2005 were valid questionnaires, with an effective rate of 92.7%. The survey subjects included 1104 males and 901 females, with a median age of 56 (22-91) years old. Working status: 609 cases (30.4%) in the work unit, 729 cases (36.4%) of retirement, 667 cases of flexible employment or unemployment (33.3%). Education level: 477 cases (23.8%) with bachelor degree or above, 658 cases (32.8%) of high school, 782 cases (39.0%) of elementary or junior high school, 88 cases (4.4%) without education. Marital status: 1789 cases (89.2%) were married, 179 cases (8.9%) divorced or widowed, 37 cases (1.8%) unmarried. Two hundred and ninety-four patients (14.7%) had metastasis when they were first diagnosed, including 203 liver metastases, 52 peritoneal metastases, and 39 other metastases. One thousand eight hundred and sixty-nine patients underwent surgical treatment, of whom 1642 (81.9%) achieved complete resection. The median time of taking imatinib was 25 (1-200) months. Common adverse reactions of imatinib included 1701 cases (84.8%) of periorbital edema, 1031 cases (51.4%) of leukopenia, 948 cases (47.3%) of fatigue, 781 cases (39.0%) of nausea and vomiting, 709 cases (35.4%) of rash, and 670 cases (33.4%) of lower extremity edema. The score of the Morisky Medication Adherence Scale showed that 392 cases (19.6%) had poor adherence, 1023 cases (51.0%) had moderate adherence, and 590 cases (29.4%) had good adherence. Univariate analysis showed that gender, age, work status, economic income, residence, education level, marriage, the duration of taking medication and adverse reactions were associated with adherence to adjuvant imatinib therapy (all P<0.05). Multivariate analysis showed that female (OR=1.264, P=0.009), non-retirement (OR=1.454, P=0.001), monthly income ≤4000 yuan (OR=1.280, P=0.036), township residents (OR=1.332, P=0.005), unmarried or divorced or widowed (OR=1.362, P=0.026), the duration of imatinib medication >36 months (OR=1.478, P<0.001) and adverse reactions (OR=1.719, P=0.048) were independent risk factors for poor adherence to adjuvant imatinib. Among patients undergoing complete resection, 324 (19.7%) had poor adherence, 836 (50.9%) had moderate adherence, and 482 (29.4%) had good adherence. Meanwhile, 55 patients with good adherence (11.4%) developed recurrence after surgery, 121 patients with moderate adherence (14.5%) developed recurrence, 61 patients with poor adherence (18.8%) developed recurrence, and the difference was statistically significant (P=0.017). Conclusions: The adherence to adjuvant therapy with imatinib in Chinese GIST patients is relatively poor. Females, non-retirement, monthly income ≤4000 yuan, township residents, unmarried or divorced or widowed, the duration of imatinib medication >36 months, and adverse reactions are independently associated with poor adherence of GIST patients. Those with poor adherence have a higher risk of recurrence after surgery. Positive interventions based on the above risk factors are advocated to improve the prognosis of patients with GIST.
