ABSTRACT
Objective:To analyze the epidemiological and clinical characteristics of patients with corona virus disease 2019 (COVID-2019) in Shenyang City.Methods:The epidemiological and clinical characteristics of 30 patients diagnosed with COVID-2019 admitted to Shenyang Sixth People′s Hospital from January 22 to February 8, 2020 were retrospectively analyzed. The independent t test, Mann-Whitney test and Fisher′s exact test were used for statistical analysis. Results:Among the 30 cases, 21 were imported, including 17 from Hubei Province and four from other provinces. Nine cases were local infections. There were 18 men and 12 women, aging from 21 to 72 years with the median of 43 years. Eight cases had underlying diseases including hypertension, diabetes, coronary heart disease and bronchitis. On admission, two (7%) cases were mild, 19(63%) cases were ordinary, eight (27%) cases were severe, and one (3%) case was critical. Clinical manifestations mainly included fever, with or without upper respiratory tract symptoms, normal, decreased or slightly increased white blood cell counts, mainly decreased lymphocyte counts, normal or increased C reactive protein, and normal procalcitonin. The computed tomography (CT) of the early stage of the lungs showed that multiple patchy ground glass shadows were mainly accompanied by consolidation, which often involved both lungs or multiple lobes of one lung. At the moment, the clinical treatment mainly included respiratory support, symptomatic treatment, antiviral treatment and anti-bacterial treatment. By February 15, a total of nine cases were cured and discharged, including one mild case, six ordinary cases, and two severe cases. In the comparisons between mild/ordinary patients and severe/critical patients, the fever duration in the severe/critical group (median 11.5 d) was significantly longer than that in the mild/ordinary group (median 2.0 d) ( Z=-2.292, P=0.022), and the laboratory tests indicated more cases with elevated D-dimer levels ( Z=-2.669, P=0.008) and neutrophilic/lymphocyte ratio >3.0 ( Z=-4.071, P<0.01). Conclusions:In Shenyang City, the early cases with COVID-19 infection are mainly imported cases, and expanding local infections gradually develop. Clinical manifestations are mainly characterized by fever and cough. Lung CT imagings show multiple ground glass shadows, mainly accompanied by consolidation. CT changes in the lungs should be closely monitored during the treatment, and CT findings in the lungs may change earlier than the clinical manifestations. Prolonged fever duration, elevated D-dimer level and neutrophil/lymphocyte ratio >3.0 could be used as early warning indicators for severe cases.

ABSTRACT
Objective To investigate the application effect of stone basket in ureteroscopic holmium laser lithotripsy for treatment of upper ureteral calculi. Methods The clinical data of 96 patients with upper ureteral calculi were retrospectively analyzed, all patients underwent ureteroscopic holmium laser lithotripsy. Forty-eight cases used the stone basket in the operation process (observation group), and 48 cases did not use the stone basket in the operation process (control group). The operation time, length of stay, success rate of lithotripsy, stone residual rate and incidence of postoperative complication were compared between 2 groups. Results The patients of 2 groups successfully completed surgery. There were no statistical differences in operation time, length of stay and incidence of postoperative complication between 2 groups (P>0.05). The success rate of lithotripsy in observation group was significantly higher than that in control group: 97.92% (47/48) vs. 75.00% (36/48), and the stone residual rate was significantly lower than that in control group:4.17%(2/48) vs. 18.75%(9/48), and there were statistical differences (P<0.05). Conclusions The stone basket in ureteroscopic holmium laser lithotripsy for treatment of upper ureteral calculi can thoroughly remove stones. It reduces the incidence of residual stones, does not affect the safety of the operation, and has good clinical value.
ABSTRACT
BACKGROUND:At present,the problems such as serious shortage of donor liver organs for transplantation,surgical injury,high incidence of surgical complications,as well as the high costs limit the development of liver transplantation,while the hepatic stem cell(HSC)transplantation provides a new pathway for the treatment of end-stage liver disease.OBJECTIVE:To introduce the source and classification of HSCs,research progress and problems of HSC transplantation for treatment of end-stage liver disease,and the clinical application prospects of HSC transplantation.METHODS:Articles were collected from CNKI and Medline database with the keywords of "hepatic stem cells,liver disease,transplantation" in both Chinese and English from 1999 to 2009.Among 87 articles,30 were included according to inclusion and exclusion criteria.Following reading titles and abstracts,original articles,and articles closely related to HSC transplantation with reliable argument and evidence and general analysis were included.Articles of repetitive studies and poor quality were excluded.RESULTS AND CONCLUSION:The HSC can be divided into liver-derived stem cells and non-liver-derived stem cells.Liver-derived stem cells include hepatic oval cells,mature liver cells and small hepatocyte-like progenitor cell.Non-liver-derived stem cells were mainly derived from embryonic stem cells,bone marrow hematopoietic stem cells and pancreatic stem cells.Currently,the research for the treatment of liver disease by HSC is still in its early stages.There are many difficult issues to be studied and solved in the discovery,separation,purification,comprehensive identification,cultivation,directed differentiation as well as clinical trials.However,as a new source of seed cells,HSC can not only replace the damaged tissue but can stimulate the receptor in tissue regeneration.Hence,compared with the clinical liver transplantation and bio-artificial liver,there are very bright future for the treatment of liver diseases by transplating HSC.
