Dignity is a core concept in bioethics. With the development of emerging life science technologies， maintaining human dignity has become the main reason for restricting the use and development of these new technologies. In bioethics， this dignity-based conservatism manifests in two forms， namely religious conservatism and secular conservatism. However， they face some difficulties respectively. Compared with conservatism， the concept of dignity advocated by the capability approach can not only avoid these difficulties but also provide a reasonable justification for people’s rational utilization and development of emerging biotechnologies.

Coronavirus disease 2019(COVID-19)is caused by novel coronavirus(SARS-CoV-2), which is widely prevalent around the world and caused global panic. Evidences show that eye transmission is possible, so the ophthalmic medical staff is more likely to be infected. Ocular manifestations of COVID-19 involve conjunctiva, corneal, sclera, anterior chamber, pupils, retina, optic nerve and visual cortex, extraocular muscles and theirs cranial nerves innervation, orbit and lacrimal system. Viral conjunctivitis is the most common ocular manifestation of COVID-19. In order to protect ophthalmic medical staff from infection and to safely carry out clinical work during the epidemic period of COVID-19, this article summarizes the ocular manifestations of COVID-19, including epidemiology, pathophysiology and clinical manifestation.

To explore the mechanism of anti-inflammatory and analgesic effect of Zanthoxyli Pericarpium based on network pharmacology and inflammatory or pain mouse models. The effective components of Zanthoxyli Pericarpium were screened out by TCMSP database. And their potential corresponding targets were predicted by PharmMapper software. The possible targets relating to inflammation and pain were mainly collected through DrugBank, TTD and DisGeNET databases. The "active ingredient-gene-disease" network diagram was constructed by Cytoscape 3.7.0 software. The network pharmacology results showed 5 potential effective compounds, which were related to 29 targets; 132 targets relating to inflammation and pain were screened out in the DrugBank, TTD and DisGeNET databases. The network analysis results indicated that the phosphatidylinositol 3-kinase catalytic subunit gamma isoform(PIK3 CG) gene may be the key to the anti-inflammatory and analgesic effect of Zanthoxyli Pericarpium. The anti-inflammatory and analgesic effects of essential oil extract and dichloromethane extract of Zanthoxyli Pericarpium were explored through the mouse model of inflammation induced by xylene or carrageenan and the mouse model of pain induced by acetic acid or formalin. The experimental results showed that essential oil extract and dichloromethane extract of Zanthoxyli Pericarpium could reduce xylene-induced ear swelling and carrageenan-induced paw swelling and decrease the number of writhing responses in mice induced by acetic acid and the licking foot time of mice in phase Ⅱ induced by formalin. Western blot results showed that Zanthoxyli Pericarpium extract could inhibit the expressions of PIK3 CG, phosphonated nuclear factor kappaB(p-NF-κB) and phosphonated p38(p-p38 MAPK) protein. The present study showed the anti-inflammatory and analgesic effect of Zanthoxyli Pericarpium through multiple components and targets, so as to provide a pharmacodynamic basis for the study of Zanthoxyli Pericarpium and its mechanism.

Objectives: To investigate the prevalence and associated risk factors of tinnitus in Sichuan and Chongqing. Methods: We designed a tinnitus epidemiological questionnaire. The multi-stage stratified cluster random sampling methods was applied to obtain study subjects in six areas (Nanchong, Jiangjin, Fengdu, Yunyang, Suining and Ya'an), which were selected for epidemiological investigation. Home visit completion of epidemiological questionnaires was conducted. The trained investigators guided the respondents to fill in the tinnitus epidemiological questionnaires, and the epidemiological status of six areas on prevalence and risk factor was investigated. SPSS 22.0 software was used for statistical analysis. Results: Sampling population were 10 289, in which 9 273 were valid questionnaires. There were 4 281 males and 4 992 females, with an average age of 47.3 years, among which 34.83% (3 230/9 273) had tinnitus. 3.99% (370/9 273) were diagnosed with bothersome tinnitus. In a multivariable logistic regression mod, the following factors were associated with onsetting of tinnitus: sleep disorder [Odds Ratio(OR)=3.74] and noise exposure(OR=1.99). The risk of disease was lowest in the age of 30-40 years old, while the risk of disease was higher for people under 30 and over 40. In another multivariable logistic regression mode, the following factors were associated with having bothersome tinnitus: older people were more likely to suffer from tinnitus, sleep disorders (OR=4.68) and noise exposure (OR=1.56). Conclusions: The prevalence of tinnitus in Sichuan and Chongqing is about 34.83%, but most of the tinnitus is short-lived and has low loudness, which will not affect the patients. Only a small number of patients with tinnitus (3.99%) persist and affect their health and need treatment. The occurrence and exacerbation of tinnitus may be related to sleep, age, and noise exposure.

Objective To investigate the prevalence and risk factors of Blastocystis infections among primary school students in Jiangjin District, Chongqing City. Methods A cross-sectional questionnaire survey was conducted among students sampled from a primary school in Jiangjin District, Chongqing City on April, 2018, and their stool samples were collected for microscopic examinations, in vitro culture and PCR assays to analyze the prevalence of Blastocystis infections and subtype of the parasite. In addition, the risk factors of Blastocystis infections among primary school students were identified using univariate analysis and multivariate logistic regression analysis. Results A total of 466 primary students were surveyed, and the subjects had a mean age of (9.81±1.66) years and included 236 males (50.64%) and 230 females (49.36%). The prevalence of Blastocystis infections was 15.24% (71/466) among the study students, and there was no significance difference in the prevalence between male and fe- male students (16.52% vs. 13.91%; χ2 = 0.616, P = 0.433). In addition, there was a significant difference in the prevalence of Blastocystis infections among grade 1 (6.35%, 4/63), grade 2 (5.17%, 3/58), grade 3 (21.74%, 15/69), grade 4 (25.30%, 21/83), grade 5 (10.19%, 11/108) and grade 6 students (20.00%, 17/85) (χ2 = 15.410, P = 0.009). There were four Blastocystis subtypes characterized (ST1, ST3, ST6 and ST7), in which ST6 was the most common subtype (45.07%, 32/71), followed by ST3 (25.35%, 18/71). Multivariate logistic regression analysis revealed that minority ethnicity [odds ratio (OR) = 4.259, 95% confidential inter- val (CI) : (1.161, 15.621)] and low maternal education level (primary school and below) [OR = 9.038, 95% CI: (1.125, 72.642)] were identified as risk factors of Blastocystis infection among primary school students in Jiangjin District, Chongqing City. Conclusions There is a high prevalence of Blastocystis infections detected among primary school students in Jiangjin District, Chongqing City, and ST6 and ST3 are predominant subtypes. Minority ethnicity and low maternal education level (primary school and below) are risk factors for Blastocystis infections in primary school students.

Objective To understand the prevalence and risk factors of Blastocystis hominis infection in inpatients in Jiangjin District, Chongqing City. Methods A cross-sectional study was conducted in a community hospital in Jiangjin District, Chongqing City, and the inpatients were surveyed by questionnaires. After obtaining the informed consent from the inpatients or legal guardians, the stool and blood samples were collected and examined by microscopy and PCR from April 17 to May 1, 2018. The univariate analysis and logistic regression analysis were used to analyze the risk factors of the B. hominis infection. Results A total of 198 hospitalized patients were investigated, and the infection rate of B. hominis was 10.61% (21/198), and the infection rate of the females (12.10%) was higher than that of the males (8.11%), but the difference was not statistically significant. The highest rate of infection was 19.23% in the age group of 10 to 20 years, followed by 17.74% in the age group of 60 years and above, and the lowest rate was 2.38% in the age group of 20 to 40 years. The difference in infection rates of B. hominis among the different age groups was statistically significant (P < 0.05). The infection rate of B. hominis in the people who used dry pail latrines was 33.30%, which was higher than that of the people who used water flush toilets (9.10%) (P < 0.05). The genotypes of B. hominis were ST1, ST3, ST6 and ST7, and ST6 and ST3 being the most predominant genotypes which accounted for 47.62% (10/21) and 38.10% (8/21) respectively, and among the infected males, the genotypes were only ST3 and ST6. The multiple logistic regression analysis showed that among the factors affecting B. hominis infection, only keeping pets was a risk factor [OR = 3.798, 95% CI (1.245, 11.581), P < 0.05]. Conclusion A high prevalence of B. hominis infection is found in the inpatients in Jiangjin District, Chongqing City, the predominant genotypes are ST6 and ST3, and keeping pets may be one of the main risk factors.

Objective To systematically explore the efficacy of four intervention regiments including desmopressin, alarm, desmopressin combined with alarm, and desmopressin combined with anticholinergic drugs in the treatment of monosymptomatic nocturnal enuresis in children by network meta-analysis. Methods The databases of PubMed, Cochrance Library, EMBase and Web of Science were systematically searched and retrieved upto August 1, 2017. Included were the randomized controlled trials (RCTs) which had any two or more of four intervention regiments (desmopressin, alarm, desmopressin combined with alarm, and desmopressin combined with anticholinergic drugs) for treatment of monosymptomatic nocturnal enuresis in children. The literature was screened according to the established inclusion and exclusion criteria, and the data extraction and quality evaluation were performed for the final inclusion of RCT. Software R 3.3.2 and STATA 14.0 were used for data analysis. Results Fifteen RCTs were included with a total of 1505 children. Network meta-analysis showed that the complete response rate and success rate of desmopressin combined with anticholinergic drugs were higher than those of desmopressin (complete reaction rate: OR=2.8, 95％ CI :1.5～5.4; success rate: OR=3.5, 95％ CI :1.7～7.5) and alarm (complete response rate: OR=2.7, 95％ CI :1.1～6.6; success rate: OR=3.8, 95％ CI: 1.6～9.0. The success rate of desmopressin combined with alarm was higher than that of alarm (OR=1.9, 95％CI: 1.1～3.4) . The recurrence rate of alarm after treatment was significantly lower than that of desmopressin (OR=0.15, 95％CI: 0.03～0.53) . The ranking results showed that the complete response rate and success rate of desmopressin combined with anticholinergic drugs were the best. The desmopressin combined with alarm can minimize the number of bed-wetting episodes per week and the recurrence rate of alarm was the lowest among the four regiments. Conclusion The effect of desmopressin combined with anticholinergic drugs is significantly better than that of alarm or desmopressin alone. The combination of desmopressin and alarm has a slight advantage or similar effect to that of single alarm or desmopressin treatment. The effect of desmopressin is similar to that of alarm. Alarm treatment has the lowest recurrence rate.

Objective To compare the clinical efficacy of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in patients with coronary heart disease and left ventricular systolic dysfunction. Methods A computer-based search in PubMed, The Cochrane Library and EMbase up to October 2017, together with reference screening, was performed to identify eligible clinical trials, cohort studies and case-control studies. The outcomes of this meta-analysis included all-cause mortality, myocardial infarction, revascularization and stroke, and the effect sizes for them were presented as relative risk (RR) with its 95% confidence intervals (CI). Results Fifteen cohort studies and 2 randomized controlled trials were finally included with a total of 11 985 patients, of whom 6 322 were in the CABG group and 5 663 in the PCI group. The result of meta-analysis showed that all-cause mortality was significantly lower in the CABG group than that in the PCI group (18.6% vs. 23.0%, RR=0.87, 95% CI 0.81 to 0.94, P<0.001). In addition, CABG was associated with a remarkably reduced risk of revascularization (RR=0.28, 95% CI 0.19 to 0.42, P<0.001) compared with PCI, with no significant difference in incidence of myocardial infarction (RR=0.78, 95% CI 0.47 to 1.32, P=0.36) and stroke (RR=1.28, 95% CI 0.89 to 1.86, P=0.18). Conclusion CABG is superior to PCI in the treatment for patients with coronary heart disease and left ventricular systolic dysfunction. Owing to the limited quality of included studies, additional large, randomized controlled trails are still required to confirm this finding.
