Objective:To analyze the clinical characteristics and experiences in diagnosis and treatment of the patients with novel coronavirus pneumonia (NCP).Methods:Clinical data of 28 patients with NCP in the Fourth People′s Hospital of Nanning from January 22 to February 5 in 2020 were collected. The clinical manifestations, epidemiological history, laboratory tests, imaging examinations and treatments of patients were analyzed retrospectively.Results:The 28 patients with NCP included one mild case, 25 ordinary cases and two severe cases. They were all positive for 2019 novel coronavirus (2019-nCoV) nucleic acid in throat swabs. There were four groups of family clusters. The clinical symptoms were mainly fever and cough, which progressed rapidly in a short period of time. Since the onset of illness, the peak values of axillary temperature of the 28 patients were 36.6 ℃ to 39.5 ℃, while five patients had no fever throughout the course of the disease with the peak temperature ≤37.0 ℃. The illness onset ranged from 1 to 12 days after exposure, and the time from the symptom onset to the positive results of the nucleic acid tests was 0 to 13 days. There were two patients presented with decreased white blood cell counts, five patients with elevated C reactive protein, six patients with abnormal alanine aminotransferase, three patients with abnormal aspartate aminotransferase, 10 patients with elevated creatine kinase, three patients with elevated creatine kinase isoenzyme, four patients with elevated lactate dehydrogenase, and all with normal procalcitonin levels. The chest computed tomography examinations showed that the common features of patients with NCP were ground glass shadows (21 cases), blurred edges (18 cases), speckles and patchy shadows (17 cases), thickening and disorder of some lung textures (seven cases), and visible band shadows (seven cases). Pulmonary lesions often progressed rapidly. A included 11-year-old child was treated with alpha-interferon alone. A total of 27 patients were treated with alpha-interferon inhalation and lopinavir/ritonavir, while four occured withdrawal due to adverse reactions. Up to February 12, nine patients had been cured and discharged who were all ordinary cases, without death cases.Conclusions:The NCP patients mostly present with fever and cough. Pulmonary lesions often progress rapidly. Respiratory pathogen testing should be conducted as early as possible and repeatedly. Disisolation should be cautious for suspected people who are negative for 2019-nCoV nucleic acid in pharynx swabs.

Objective:To explore the occurrence of adverse reactions of lopinavir/ritonavir (LPV/r) in the treatment of coronavirus disease 2019 (COVID-19).Methods:The medical records of patients with COVID-19 who received LPV/r treatment in the Fourth People′s Hospital of Nanning from January 24th to February 6th, 2020 were collected and the occurrence of adverse events during the treatment was retrospectively analyzed. According to the 5 principles of adverse drug reaction correlation evaluation proposed in the Handbook of Adverse Drug Reaction Reporting and Monitoring in China, adverse events that were certainly related, probably related, and possibly related to LPV/r were defined as LPV/r-related adverse reactions. The incidence of adverse reactions was calculated and the main clinical manifestations and severity of adverse reactions [grade 1 (mild), grade 2 (moderate), grade 3 (severe), grade 4 (life-threatening), and grade 5 (death); grade 3-5 was defined as severe adverse reaction] were analyzed. Results:A total of 28 patients were enrolled in the analysis, including 13 males and 15 females, aged from 18 to 70 years with an average age of 44 years. The courses of treatment with LPV/r of patients ranged from 2 to 12 days, with a median course of 6 days. Of the 28 patients, 18 developed LPV/r related adverse reactions, with an incidence of 64.3%. The LPV/r-related adverse reactions in 18 patients included gastrointestinal reactions in 14 patients (grade 1 in 13 patients and grade 2 in 1 patient), bradycardia in 2 patients (grade 2 in both patients), and acute hemolysis in 1 patient (grade 3), and liver injury in 1 patient (grade 3), and no grade 4 or 5 adverse reactions occurred. The incidence of severe adverse reactions was 7.1%. Thirteen patients with grade 1 adverse reactions did not affect the treatment, and the symptoms were relieved after 2-7 days of continuous medication. LPV/r was discontinued in 5 patients with grade 2 or 3 adverse reactions, 4 of whom received symptomatic treatment, and the symptoms disappeared 2-10 days later.Conclusions:The incidence of adverse reactions in COVID-19 patients treated with LPV/r in our hospital was 64.3%. LPV/r mainly leads to mild gastrointestinal reactions and can also lead to bradycardia, acute hemolysis, and liver injury. Blood routine, liver function, and electrocardiogram need to be monitored during the treatment.

Autophagy, a cellular housekeeping process, is indispensable to controlling the homeostasis of cytoplasm by removing unused proteins and damaged cell organelles. This process involves different types of human diseases, including cancers, neurodegenerative diseases and infectious diseases. Neurodegeneration is a critical pathological process of many eye diseases, such as glaucoma and age-related macular degeneration. The retina and all intraocular cells are constantly exposed to environmental stress and injuries, including oxidative stress and starvation, which lead to autophagy. Autophagy promotes cell survival through the recycling of metabolic precursors, or promotes cell death if autophagy is over-active. Additionally, autophagy and apoptosis have been shown to be harmonious or contrasting, depending on different experimental contexts. All of this contributes to the pathogenesis of many diseases. This paper reviews the mechanisms and regulation involved in autophagy, current understandings of neuronal autophagy in glaucoma and retina and strategies for therapeutic modulation.
