Abstract
Objective: To analyze the difference in depression symptoms and influencing factors between urban and rural elderly people aged ≥65 years old in Anhui Province. Methods: Based on the data from a survey of 68 communities in Anhui Province that implemented the National Elderly Psychological Care Project from 2019 to 2020, the current status of depression symptoms in the elderly was evaluated using the Patient Health Questionnaire-9 (PHQ-9). The difference in the detection rate of depression symptoms between urban and rural elderly people with different characteristics was compared by using the χ2 test. The logistic regression model was used to analyze the relevant factors of depression symptoms in urban and rural elderly people. Results: A total of 15 532 elderly people aged≥65 years old were included in the survey. The detection rate of depressive symptoms was 7.12%, which was higher in rural areas (9.08%) than in urban areas (6.48%). Logistic regression showed that chronic diseases were risk factors for depressive symptoms in elderly people from both urban and rural areas. Positive attitudes towards aging and good mental resilience were protective factors for depressive symptoms in elderly people. Having hobby (OR=0.64, 95%CI: 0.45-0.91), good relationship with children (OR=0.56, 95%CI: 0.41-0.76), good relationship with spouse (OR=0.51, 95%CI: 0.37-0.71), and having at least 6 friends (OR=0.48, 95%CI: 0.32-0.71) were the protective factors for depressive symptoms in urban elderly people. A good relationship with neighbors (OR=0.58, 95%CI: 0.41-0.82) and having 1-2 friends (OR=0.40, 95%CI: 0.25-0.64) were the protective factors for depressive symptoms in rural elderly people. Women (OR=1.49, 95%CI: 1.06-2.10) and higher education level (OR=1.81, 95%CI: 1.19-2.74, compared with illiterate/semi-illiterate in primary school; OR=2.94, 95%CI: 1.82-4.76, compared with illiterate/semi-illiterate in junior high school and above) were the risk factors for depressive symptoms in rural elderly people. Conclusion: There are differences between urban and rural areas in depressive symptoms among elderly people in Anhui Province. The detection rate of depression symptoms among rural elderly people is higher, and the influencing factors of depressive symptoms between urban and rural elderly people are also different, which should be treated specifically in the implementation of intervention measures.

Abstract
Objective: To analyze the safety and efficacy of using novel oral anticoagulants (rivaroxaban and others) in patients with cirrhosis accompanied with portal vein thrombosis (PVT). Methods: Clinical research literature published from the establishment of the database to June 20, 2021, was retrieved from PubMed, Web of Science, CNKI, Wanfang, and Weipu databases by combining subject terms and free words. RevMan software was used for the random group meta-analysis model. Results: In terms of PVT recanalization, the novel oral anticoagulants (such as low molecular weight heparin and others) had a higher recanalization rate than traditional anticoagulants (OR = 13.75, 95%CI 3.58-52.9, P = 0.000 1). In terms of bleeding, the novel oral anticoagulants did not increase the risk of bleeding compared with traditional anticoagulants (OR = 2.42, 95%CI 0.62-9.41, P = 0.20). Conclusion: The novel oral anticoagulant drugs are superior to traditional anticoagulants in terms of the occurrence of PVT recanalization; however, there is no statistically significant difference in terms of the occurrence of bleeding between the two groups.

Abstract
Molecular dynamics (MD) simulation is used to study the corrosion inhibition mechanism of cysteine (Cys), glutamic (Glu) and glycine (Gly) for copper in hydrochloric acid solution. The adsorption energy and radial distribution function results show that all three amino acids can spontaneously adsorb on Cu (111) surface by chemical adsorption. The absolute value of adsorption energy and intensity is Cys > Glu > Gly. The diffusion coefficient and relative concentration curve show that all the three amino acids can inhibit the diffusion and aggregation ability of corrosion particles, so the three amino acids not only can slow down the aggregation of corrosive particles, but also effectively repel corrosive particles to protect the substrate. The inhibition ability obtained by the MD simulation shows the trend of Cys > Glu > Gly, which is consistent with the experimental results. The inhibition efficiency is determined by both the adsorption strength on the substrate surface and inhibition ability for the diffusion and aggregation ability of corrosion particles.

Abstract
The clinical features, imaging features, treatment methods and pathological features of 27 patients with metanephric adenoma were analyzed. It was found that the clinical features and imaging features of metanephric adenoma were difficult to differentiate from renal malignantology. Pathology can be clearly diagnosed and some can be combined with malignant components. Nephron sparing surgery is the first choice, and the prognosis is good, but still need regular follow-up.

Abstract
Objective: To compare the trigger delay and work of trigger between neurally adjusted ventilatory assist (NAVA) and pressure support ventilation (PSV) in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients with intrinsic positive end-expiratory pressure (PEEP) during mechanical ventilation. Methods: AECOPD patients with intrinsic PEEP (PEEPi) greater than or equal to 3 cmH(2)O (1 cmH(2)O=0.098 kPa) were enrolled during invasive mechanical ventilation. Subjects were ventilated with low, medium and high pressure under either NAVA or PSV mode. Servo Tracker software continuously recorded the waveform of ventilator and respiratory mechanics indexes (including respiratory frequency, inspiratory tidal volume (Vti), minute ventilation volume (VE), peak airway pressure (PIP), inspiratory time), and calculated trigger and expiratory conversion delay time, work of trigger and total work of breath. Results: A total of 14 AECOPD patients were enrolled with the average PEEPi (4.3±1.3) cmH(2)O. PSV inspiratory trigger delay time was positively correlated with PEEPi (r=0.913, P<0.05). Compared with PSV, NAVA significantly decreased trigger delay time in low, medium and high pressure level groups [(48±17) ms vs. (167±86) ms, (63±65) ms vs. (247±240) ms, (63±49) ms vs. (342±192) ms,respectively all P<0.05]. Similar results were shown as to work of trigger [(0.92±0.36) μV∙s vs. (1.22±0.70) μV∙s, (1.08±0.51) μV∙s vs. (1.62±1.25) μV∙s, (1.20±0.96) μV∙s vs. (2.29±1.02) μV∙s, all P<0.05]. Trigger delay time increased according to the increase of pressure level in PSV mode. Conclusion: The presence of PEEPi in AECOPD patients leads to obvious trigger delay under PSV mode, which is positively correlated with PEEPi level. NAVA significantly reduces trigger delay time and work of trigger compared with PSV mode.

Abstract
Objective: To investigate the killing effect of low-temperature plasma (LTP) on HepG2, A549 and HeLa cell lines and explore its possible mechanism. Methods: The inhibitory effect of LTP on the proliferation of HepG2, A549 and HeLa cells was determined by MTT assay. Transmission electron microscopy was used to observe the ultrastructural changes of HepG2, A549 and HeLa cells treated with LTP. Cell apoptosis was detected by Muse cytometry. Western blot was used to detect the expression of apoptosis-related proteins. Results: The survival rates of LTP-irradiated HepG2 cells (irradiated for 107 s), HeLa cells (irradiated for 121 s) and A549 cells (irradiated for 127 s) were 50%. LTP destroyed the ultrastructure of HepG2, A549 and HeLa cells to different degrees, showing nuclear fragmentation and organelle damages. The apoptosis rates of the three cell lines were increased at 24 h after exposure to LTP for 1/6 IC50 irradiation time. Furthermore, LTP irradiation also suppressed the protein expression of Bcl-2 and XRCC1 and increased that of Bax. Conclusions: LTP has an obvious killing effect on HepG2, A549 and HeLa cancer cell lines. This effect may be related to the induction of cell apoptosis and inhibition of DNA repair.

Abstract
We aimed to evaluate the bioequivalence of clopidogrel in healthy Chinese volunteers after administration of a single oral dose. We administered a single oral dose of 75 mg clopidogrel (test and reference) to 32 healthy Chinese volunteers according to an open, randomized, crossover design. The concentration of clopidogrel acid (carboxylic metabolite of clopidogrel) in the plasma was determined using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Bioequivalence of the test and reference preparations were calculated using analysis of variance and one-sided t-test by using the DAS 2.0 software. The pharmacokinetic parameters of the test and reference preparations were as follows: peak plasma concentration (Cmax), 1351.101 ± 654.955 ng/mL and 1184.652 ± 607.713 ng/mL; area under the curve, 2642.017 ± 1093.848 ng·h/mL and 2780.666 ± 1283.100 ng·h/mL; and time to reach Cmax (Tmax), 0.789 ± 0.318 h and 0.953 ± 0.633 h, respectively. The relative bioavailability of the formulation was 101.7 ± 35.3%, which indicated that the test preparation was bioequivalent to the reference drug.

Abstract
PPARD encodes peroxisome proliferator-activated re-ceptor delta, which has been shown to play an important role in control-ling lipid metabolism and atherosclerosis. In this case-control study, we explored the relationship between PPARD rs2016520 polymorphism and coronary heart disease (CHD) in a Han Chinese population. A to-tal of 657 CHD cases and 640 controls were included in the associa-tion study. rs2016520 polymorphism genotyping was performed using the melting temperature-shift polymerase chain reaction method. The PPARD rs2016520-G allele reduced CHD risk by 17.9% (χ(2) = 5.061, P = 0.025, OR = 0.821, 95%CI = 0.692-0.975). Furthermore, a signifi-cant difference in CHD risk was observed for the PPARD rs2016520 polymorphism in the dominant model (AG + GG vs AA: χ(2) = 4.751, degrees of freedom (df) = 1, P = 0.029, OR = 0.784, 95%CI = 0.631- 0.976). Analysis by age suggested that the G-allele decreased CHD risk by 14.8% in ages greater than 65 years (χ(2) = 4.446, P = 0.035, OR = 0.852, 95%CI = 0.684-1.060). In contrast, meta-analysis of PPARD rs2016520 among 3732 cases and 5042 controls revealed no associa-tion between PPARD rs2016520 and CHD (P = 0.19). We found that the PPARD rs2016520-GG genotype decreased CHD risk in a Han Chinese population. Moreover, we found an association between serum high-density lipoprotein cholesterol level and PPARD rs2016520 in senior individuals aged ≥ 65 years. The meta-analysis revealed no association between PPARD rs2016520 and CHD, suggesting ethnic differences in the association between the PPARD locus and CHD.

Abstract
Background: Side population (SP) cells and their relationship to stem cell-like properties have been insufficiently studied in colorectal cancer (CRC). MicroRNAs (miRNAs) have attracted much attention but their roles in the maintenance of SP phenotype remain unclear. Methods: The SPs from CRC cell lines and primary cell cultures were analysed for stem cell-like properties. MiRNA microarray analysis identified miR-328 as a potential stemness miRNA of SP phenotype. The level of miR-328 expression in clinical samples and its correlation with SP fraction were determined. Gain-of-function and loss-of-function studies were performed to examine its roles in cancer stem-like SP cells. Furthermore, bioinformatics prediction and experimental validation were used to identify miR-328 target genes. Results: The SP cells sorted from CRC possess cancer stem cell (CSC)-like properties, including self-renewal, differentiation, resistance to chemotherapy, invasive and strong tumour formation ability. MiR-328 expression was significantly reduced in SP cells compared with Non-SP cells (P<0.05). Moreover, miR-328 expression was downregulated in CRC (n=33, P<0.05) and low miR-328 expression tend to correlate with high SP fraction (n=15, r=0.6559, P<0.05, Pearson's correlation). Functional studies indicated that miR-328 expression affects the number of SP cells. In addition, miR-328 overexpression reversed drug resistance and inhibited cell invasion of SP cells. Furthermore, luciferase reporter assay demonstrated that miR-328 directly targets ABCG2 and MMP16 and affects the levels of mRNA and protein expression in SP cells. Conclusion: These findings indicate that CRC contain cancer stem-like SP cells. MiR-328 has an important role in maintaining cancer stem-like SP phenotype that may be a potential target for effective CRC therapy.

Abstract
Seventy-nine consecutive patients with symptomatic atherosclerotic stenosis > or = 50% of intracranial vertebrobasilar artery (VBA) were treated by elective stenting. There were five strokes within 30 days, and three strokes in the VBA territory after 30 days (mean of 812 days). The annual stroke rate in the VBA territory (including any stroke and death within 30 days) was 4.6%. At the last follow-up time, 73 patients were independent (modified Rankin scale grade < or = 2). The outcome compares favorably with medical therapy.

Abstract
OBJECTIVE To test whether symptomatic severe intracranial atherosclerotic stenosis was associated with a higher subsequent stroke risk than moderate stenosis after elective angioplasty with a balloon-expandable stent and to explore which factors were associated with the subsequent stroke. METHODS Between September 2001 and June 2005, there were 220 symptomatic intracranial atherosclerotic stenoses in 213 patients undergoing elective stenting at our institute. Of these stenoses, 126 in 121 patients were > or =70% severe stenoses, and 94 in 92 patients were 50% to 69% moderate stenoses. Primary endpoints included lesion-related ischemic stroke, and symptomatic brain or subarachnoid hemorrhage. RESULTS Ten primary endpoint events occurred in the severe stenosis group (six within 30 days and four in mean follow-up of 26.0 months after 30 days), and seven occurred in the moderate stenosis group (four within 30 days and three in mean follow-up of 27.6 months after 30 days). There was no significant difference in cumulative probability of primary endpoints between the severe (7.2% at 1 year and 8.2% at 2 years) and moderate (5.3% at 1 year and 8.3% at 2 years) stenosis groups. No single factor was found to be associated with primary endpoints in the moderate stenosis group. Multivariable analysis revealed that stent failure was the only predictor of primary endpoints in the severe stenosis group (hazard ratio 5.31, 95% CI 1.35 to 20.91). CONCLUSION Symptomatic severe intracranial atherosclerotic stenosis did not present a higher subsequent stroke risk than moderate stenosis after elective angioplasty with a balloon-expandable stent. Patients with severe stenosis may benefit from successful stent placement, and randomized trials are necessary to demonstrate this possible benefit.

Abstract
OBJECTIVE To study the frequency, clinical course, and functional outcome of perforator stroke (PS) resulting from elective stenting of symptomatic intracranial stenosis. METHODS Between September 2001 and November 2004, 169 consecutive patients with 181 symptomatic intracranial stenoses underwent stenting procedure at our institute. The preoperative perforator infarct adjacent to the stenotic segment (PIAS) on MRI was evaluated blindly. Patients who developed PS after stenting were enrolled. Each patient was assessed by an experienced stroke neurologist by neurologic examination and NIH Stroke Scale score every day until discharge and at day 30, and by modified Rankin Scale (mRS) score at the end of the first, third, and sixth month, and then at intervals of 6 months. RESULTS PS frequency was 3.0% (5/169 patients). The patients with preoperative PIAS had a higher frequency of PS and PS exacerbation, resulting from intracranial stenting (8.2%, 4/49), vs patients without preoperative PIAS (0.8%, 1/120; p = 0.031). Four PSs occurred during the procedure and one 10 hours after stenting. Four PSs reached the maximum deficit almost at once, and one after 2 hours from onset. All five patients were functionally independent (mRS <or= 1) within 12 months. CONCLUSION Patients with preoperative perforator infarct adjacent to the stenotic segment have a higher perforator stroke frequency after elective stenting of intracranial stenosis. Most perforator strokes occur during the procedure and reach the maximum deficit almost immediately. Functional outcomes are relatively good.

Abstract
In a preliminary study, carriers of hepatitis B virus were treated with Cinobufotalin, a preparation from toad, for 1-3 course of treatment. Results indicated that negative conversion rate was markedly higher in the treated groups (21.09%, 38.89%, 63.64% and 50%) than that of control groups (2.1%, 10.87%, 33.33% and 7.7% P < 0.001). By the end of treatment, positive conversion rate of anti-HBs and anti-HBe were also markedly higher in the former (19.29% and 23.45%) than that in the latter (4.26% and 7.14% P < 0.001). During the follow-up of 3-6 months, the positive rate of HBeAg in treated group (50%) raised as compared with the control group (20% P = 0.08). The results indicated that Cinobufotalin had a significant effect in inhibiting the replication of HBV.

Abstract
439 cases of epidemic hemorrhagic fever (EHF) in the febrile stage of the disease were randomly divided into two groups. 226 cases in therapeutic group were treated with daily intravenous drip of 60-100 ml potenlini for 3 days. Other measures of treatment in this group was just the same as those in the control group. The results showed that the duration of both the febrile stage and the hypotensive shock stage were shorter and the rate of recovering from hypotensive shock stage and oliguric stage in the therapeutic group (P less than 0.01) was higher as compared with the control group. BUN, ALT, urinary protein, white blood cells and platelets returned to normal level earlier than expected (P less than 0.01). The occurrence rate of complication and case fatality rate in therapeutic group were lower. The research showed that potenlini in the treatment of EHF has effects. But it has not remarkable effects on immune adjustment.
