Objective:To understand the epidemiological and clinical characteristics of human infection with avian influenza A(H3N8) virus and the molecular biological characteristics of the pathogen, and provide scientific evidence for the prevention and control of human infection with avian influenza A(H3N8) virus.Methods:An epidemiological investigation was conducted for a case of human infection with avian influenza A(H3N8) virus in Changsha in May 2022 to collect the information about exposure history, route of infection, onset and treatment, potential contacts and other possible exposures for a descriptive analysis. Nucleic acid detection and gene sequencing were used to detect the pathogen and analyze the genetic characteristics.Results:The case had a history of exposure to live poultry trading market 6 days before the onset of illness. Subtypes H3 and N8 of avian influenza virus were detected in live poultry markets. Deep gene sequencing showed that the virus had adaptive mutations in mammals, reduced sensitivity to alkamine agent, and no resistance mutations related to neuraminidase inhibitors and polymerase inhibitors were detected.Conclusion:The case was infected due to exposure to the live poultry market environment contaminated by avian influenza A(H3N8) virus, and no human to human transmission was found.

Aromatase deficiency (AD) is a rare autosomal recessive genetic disease caused by loss-of-function mutations in aromatase gene (CYP19A1), leading to congenital estrogen deficiency syndrome. Both mothers of AD patients during pregnancy and female AD fetus show virilization, while male patients are usually diagnosed in adulthood due to continued height increase and metabolic abnormalities. In 2019, a patient with AD was admitted in the Second Xiangya Hospital. The patient was a 37-year-old adult male who continued to grow linearly after adulthood. His estradiol was below the measurable line, the follicle-stimulating hormone (FSH) increased, bone age delayed, epiphysis unfused, and the bone mass reduced. CYP19A1 gene detection showed that c.1093C>T, p.R365W was homozygous mutation. This disease is rare in clinic. Clinicians need to raise awareness of the disease for early diagnosis and treatment to improve the long-term prognosis of patients.

[Summary] _ Osteoporosis and diabetes mellitus are diseases which affect public heath severely, and osteoporotic fracture risk is increased in patients with diabetes. During recent years, new anti-diabetes drugs glucagon-like peptide-1(GLP-1) analogues and its receptor agonists had been used for diabetes treatment. As the research continues, besides of anti-diabetes, GLP-1 analogues are also found to play a role in bone metabolism and central nervous system by stimulating bone formation, inhibiting bone resorption, and nerve protection/nutrition, etc, suggesting that it may play an important role in the treatment of other diseases such as osteoporosis.

Periostin is preferentially expressed in the periosteum, which covers a large majority of bones.Periostin has been reported to promote osteoblast proliferation, adhesion, and differentiation, involving bone repair process, response to mechanical stimulation and parathyroid hormone (PTH), regulating bone development/ remodeling and bone strength.Circulating periostin may serve as a candidate of biological markers for bone metabolism.

Objective To analyze the transmission pattern of Chikungunya (CHIK) fever in community and evaluate the effectiveness of mosquito control, case isolation and other key control measures by using ordinary differential equation (ODE) model.Methods According to natural history of CHIK, an ODE model for the epidemiological anaysis of CHIK outbreak was established.The key parameters of the model were obtained by fitting the model with reported outbreak data of the first CHIK outbreak in China.Then the outbreak characteristics without intervention, the effectiveness of mosquito control and case isolation were simulated.Results Without intervention, an imported case would cause an outbreak in a community with population of 11 000, and cumulative case number would exceed 941 when the total attack rate was 8.55％.The results of our simulation revealed that the effectiveness of case isolation was not perfect enough when it was implemented alone.Although the number of cases could be decreased by case isolation, the duration of outbreak would not be shortened.Differently, the effectiveness of mosquito control was remarkable.In addition, the earlier the measure was implemented, the better the effectiveness would be.The effectiveness of mosquito control plus case isolation was same with mosquito control.Conclusion To control a CHIK outbreak, mosquito control is the most recommended measures.However, case isolation is also necessary as the supplementation of mosquito control.

1,3-propanediol is an important raw material in chemical industry. Microbial conversion of glycerol or glucose into 1,3-propanediol has been given much attention due to its renewable resource, mild reaction conditions, and other advantages. It is a challenge to efficiently separate 1,3-propanediol from a mixture of multiple components, such as 1,3-propanediol, 2,3-butanediol, water, residual glycerol, ethanol, macromolecules and salts, for the reason that 1,3-propanediol, glycerol and 2,3-butanediol are all very hydrophilic and have intense polarity. The conventional evaporation and distillation techniques used in the purification of 1,3-propanediol suffer from the problem of high energy consumption and low recovery. It makes the recovery of 1,3-propanediol from a fermentation broth become a bottleneck in industrial production. The down-stream processing of biologically produced 1,3-propanediol mainly includes the removal of protein, salts, water and other impurities. This paper analyze the research progress of these separation technologies and point out the developing direction worth further investigation.
