Objective To estimate the key epidemiological parameters, including the serial interval (SI), basic reproduction numbers (R₀), and time-dependent reproduction numbers (R_t) based on the case data of COVID-19 published on the official website of Shaanxi Provincial Health Commission. Methods The method of maximum likelihood estimation was used to fit the probability distribution of SI, and three parametric models including Gamma, Weibull, and Lognormal distributions were adopted to estimate the distribution of SI. The optimal model was selected by the corrected Akaike information criterion (AICc). Based on nonlinear regression model the cumulative number of confirmed cases was fit to the growth rate r of the Richard growth model to estimate R₀. The R_t was calculated based on the Bayesian framework. Results A total of 49 transmission chains were discovered from 245 local confirmed cases in Shaanxi Province. The Gamma distribution was the optimal model to fit the SI here by AICc. Using the Gamma distribution, the mean SI was estimated to be 6.3 days (95%CI:5.98 - 6.43) with a standard deviation (SD) of 3.94 days (95%CI: 3.01 - 5.03). Using the Richard growth model, the growth rate was estimated to be 0.23 (95% CI: 0.21 - 0.24) and the basic reproduction number in Shaanxi to be 3.11 (95%CI: 2.91 - 3.40). R_t showed an overall downward trend, and fell below 1 on February 10 (R_t=0.95（95%CI: 0.76-1.16)), and stabilized at around 0.35 on February 18. Conclusion The SI of COVID-19 is relatively shorter than that of MERS and SARS, while the R₀ is relatively larger, and R_t is on a downward trend, which suggests COVID-19 is a highly transmissible infectious disease. The control measures including the isolation and treatment of confirmed patients, quarantine and observation of suspected cases, contact tracing, improvement of public awareness, and adoption of self-protection measures can effectively reduce the COVID-19 outbreak.

The facultative anaerobic and strict anaerobic microorganisms enriched and acclimated during the anaerobic digestion process are crucial for the efficiency of the anaerobic digestion system. Most of the problems encountered during running anaerobic digestion processes could be effectively improved via stimulation of microbial metabolic activity. Benefited from the rapid development of microbiome techniques, deeper insights into the microbial diversity in anaerobic digestion systems, e.g. the microbe-microbe interactions and microbe-environment interactions, have been gained. A complex and intricate metabolic network exists in the anaerobic digestion system of solid organic wastes. However, little is known about these interactions and the underlying mechanisms. This review briefly summarized the representative interactions between microbial communities during anaerobic digestion process discovered to date. In addition, typical issues encountered during the anaerobic digestion of solid organic wastes and how microbes can tackle and alleviate these issues were discussed. Finally, future priorities on microbiome research were proposed based on present contribution of microbiome analysis in anaerobic digestion system.

Objective: To understand the current status of health related quality of life among primary and middle school students aged 9 to 15 years old in Henan Province, and to explore its relationship with negative emotions and social support. Methods: Between January and June 2016, 24 primary and middle schools were selected from 6 cities of Henan Province, and 5 867 primary and middle school students were included and completed the Pediatric Quality of Life Inventory Measurement, Stress Anxiety Depression Scale, Perceived Social Support Scale. Hierarchical linear regression analysis was used to examine the moderating effect of social support. Results: The total score of health related quality of life of primary and middle school students in Henan was (81.21±12.49). There were statistically significant differences in the quality of life among primary and middle school students with different gender, study period, family monthly income, subjective parental relationship and parental education ( P <0.05). Negative emotions were negatively correlated with quality of life ( r =-0.51, P <0.01) and social support ( r =-0.30, P <0.01), while social support was positively correlated with quality of life ( r =0.29, P <0.01). Regression analysis showed that negative emotional was negatively associated with quality of life ( β =-0.23, P <0.01), while social support was positively associated with quality of life ( β =0.16, P <0.01). The interaction of negative emotions and social support was negatively associated with quality of life ( β =-0.18, P <0.01). Conclusion Health related quality of life among 9-15 year old primary and middle school students in Henan province is satisfactory. Social support might buffer the negative impact of negative emotions including depression, anxiety and stress on quality of life of primary and secondary school students.

Objective:To investigate the clinical characteristics, treatment and prognosis of QARS1 gene related glutaminyl-tRNA synthetase deficiency.Methods:To summarize and analyze the clinical manifestations, imaging, laboratory examination, genetic variant characteristics and treatment of three patients from the Fujian Medical University Affiliated Union Hospital, the 900th Hospital of People's Liberation Army, the First Medical Center of People's Liberation Army General Hsopital carrying compound heterozygous variations in QARS1 gene with a long-term follow-up in China. A literature search was conducted using Wanfang, Weipu, China National Knowledge Infrastructure (CNKI) and Pubmed databases with the keywords "QARS", "QARS1" and "glutaminyl-tRNA Synthetase"(up to December 2019). Results:Case 1, a female 53 days of age, was admitted to the Fujian Medical University Affiliated Union Hospital for treatment because of the complaint of repetitive seizures for one month after birth and fever for one day. The seizure occurred within the first 2 hours of life with multiple forms and often had a status as persisted from hours to days. The seizures were resistant to many anti-epilepsy drugs (AED) and ketogenic diet but later controlled by clonazepam. However, she died at the age of seven years. Case 2 (younger brother of case 1), a one-hour-old boy, was hospitalized because of seizures after birth for 1 hour. Intrauterine growth retardation was discovered during late-pregnancy. The boy presented seizures and microcephaly immediately after birth, and his epilepsy was pharmacoresisitant. Case 3, an 8-month-old girl, was admitted due to recurrent convulsions for nearly two months. The girl had mild developmental retardation and hypotonia after birth. The infantile spasm was observed at her age of 6 months and disappeared under treatment with Vitamin B6, vigabatrin combined with adreno-cortico-tropic-hormone and magnesium sulfate. However, the seizure pattern turned to tonic seizures later. She was seizures free now with clobazam and zonisamide treatment. All of them manifested as a syndrome composed of severe global developmental retardation, progressive microcephaly, hypotonia from the very beginning, mild hypoproteinemia and diffuse brain atrophy. Genetic studies revealed compound heterozygous variations of QARS1 gene which were not reported previously . A review of the literature reported a total of 22 patients from 18 unrelated families all over the world. Except for 5 cases without epilepsy,all the patients shared very similar clinical manifestations as classic pentalogy. The recommended effective treatment for epilepsy has not been reported yet. Conclusions:Glutaminyl-tRNA synthetase deficiency caused by QARS1 gene variations manifested as a clinical syndrome′s pentalogy, characterized by microcephaly, cerebral atrophy, intractable early-onset epileptic encephalopathy, global developmental retardation and severe muscle hypotonia.
