Objective To compare the protecting effect of hypoxia preconditioning(HP) and deferoxam-ine preconditioning (DP)on transplanted livers and to search a protecting method which is suitable for clini-cal practice.Methods SD rats are randomly divided into four groups:sham operation group (S),analogic transplantation group (AT),deferoxamine preconditioning group (DP) and hypoxia preconditioning group (HP).Twenty-four hours after operation,several factors of each group were measured respectively,inclu-ding deterioration of histomorphology,hepatic zymogram in the serum,hypoxia inducing factor-1 (HIF-1α)and malonaldehyde (MDA) in hepatic tissue.Results The levels of alanine aminotransferase (ALT),glu-tamic oxalacetic transaminase (AST) and alkaline phosphatase (ALP) in AT group,DP group and HP group were higher than S group's.Levels of ALT,AST,ALP in AT group were dramatically high,hepatic tissue suffers from edema,degeneration even necrosis.By contrast,the pathological change is milder in DP group and HP group.HIF-1α in hepatic tissue of AT group was lower than that in DP group and HP group,MDA was higher than two latters (P < 0.05).Conclusion DP can protect transplanted liver as same as HP,however,DP is more suitable for clinical practice.

Objective:To explore the changes of levels of coagulation factors at acute phase (within one week) of aneurysmal subarachnoid hemorrhage (aSAH) and their relations with deep venous thrombosis (DVT).Methods:Two hundred and two aSAH patients (aSAH group), admitted to our hospitals from March 2015 to March 2019, were selected in our study, and these patients were divided into a combined DVT subgroup and a uncombined DVT subgroup according to whether they were combined with DVT on the first and third d of onset. One hundred healthy physical examiners whose age and gender matched with those of aSAH group were selected as control group; one, 3, 5, and 7 d after onset, and one d after enrolling of subjects from the control group, thromboelastogram (TEG) was used to detect the R value of TEG (TEG-R) in all subjects. One, two, 3, 4, 5, 6 and 7 d after onset, color Doppler ultrasonography was used to determine whether aSAH patients had DVT.Results:A total of 73 patients (36.14%) were combined with DVT at acute stage of aSAH; 66 were with asymptomatic thrombosis and 7 with symptomatic thrombosis; 59 were with lower extremity intermuscular vein thrombosis and 14 were with intermuscular vein thrombosis. The incidence of DVT (68/73 [93.2%]) peaked on the 1 st-3 rd d of onset. The TEG-R of patients in aSAH group was statistically lower than that of the control group on the 1 st-3 rd d of onset ( P<0.05); the TEG-R of patients in aSAH group on the 1 st-3 rd d of onset was significantly lower than that on 5 th and 7 th d of onset ( P<0.05). The TEG-R of patients in combined DVT subgroup was significantly lower than that of the uncombined DVT subgroup ( P<0.05). Conclusions:Hyperfunction of coagulation factors at acute stage of aSAH is noted within one-3 d of onset; the incidence of DVT is the highest within 3 d of onset, mainly featured as asymptomatic intermuscular venous thrombosis. Whether or not aSAH would combine with DVT is associated with hyperfunction of coagulation factors.

Objective:To analyze the proportion of patients with acute primary angle-closure glaucoma (PACG) after the outbreak of coronavirus disease 2019 (COVID-19) in patients undergoing glaucoma surgery and the factors influencing morbidity.Methods:A cross-sectional study was performed.The cluster sampling method was used to collect 141 glaucoma patients hospitalized for glaucoma surgery after the outbreak of COVID-19 in Xuzhou First People's Hospital from December 16, 2022, to January 16, 2023, and 231 glaucoma patients hospitalized for surgery in the same 1-month period from 2019 to 2020, 2020 to 2021, 2021 to 2022 through the hospital information system.Ninety-two eyes of 92 patients with acute PACG after the outbreak were selected as a study group, and 21 eyes of 21 patients with acute PACG hospitalized during the same 1-month period from 2021 to 2022 were selected as a control group.The proportion of patients with different types of glaucoma during the observation period was analyzed.The proportion of patients with acute PACG and the clinical characteristics of acute PACG were analyzed, including age, sex, visual acuity, intraocular pressure (IOP), and anterior chamber angle status.Epidemiological data such as the use of anti-cold medications, and changes in living habits and moods (including daily water intake and anxiety) of patients after COVID-19 infection were obtained by telephone follow-up.Anxiety levels of patients in the study group were assessed using the Hospital Depression and Anxiety Scale (HADS).The triggering factors of acute PACG attack after the COVID-19 outbreak were analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Xuzhou First People's Hospital (No.xyyll[2023]114).Written informed consent was obtained from each subject.Results:The proportion of acute PACG patients in Xuzhou First People's Hospital within one month after the outbreak in 2022 to 2023 increased significantly compared with the same period in 2021 to 2022, 2020 to 2021 and 2019 to 2020, and the differences were statistically significant ( χ2=31.066, 33.331, 20.804; all at P<0.001).There was no statistical significance in the distribution of the number of eyes with different grades of visual acuity, IOP, the number of eyes with IOP ≥30 mmHg (1 mmHg=0.133 kPa), and the distribution of the number of eyes with different anterior chamber angles between the two groups (all at P>0.05).Patients in the control group had no history of COVID-19 infection or use of cold medicines at disease onset.During disease onset, all 92 (100%) patients in the study group had positive COVID-19 nucleic acid test results, of which 57 (61.96%) patients had a history of oral anti-cold medication use.During the same period, 49 (100%) hospitalized patients with other types of glaucoma had positive COVID-19 nucleic acid test results, of which 20 (40.82%) patients had a history of oral cold medication.There was a statistically significant difference in the proportion of patients taking oral cold drugs between acute PACG and other types of glaucoma in the study group ( χ2=5.764, P=0.016).During the outbreak of COVID-19, the study group reported that the daily water intake had increased to varying degrees than before.In the study group, 76 patients had anxiety, accounting for 82.6%.Multiple linear regression analysis showed that IOP=19.052+ 0.009×daily water intake+ 0.858×HADS score ( R2=0.780), and the standardized coefficients of daily water intake and HADS score were 0.542 and 0.452, respectively.Daily water intake had a greater effect on IOP than HADS score. Conclusions:The proportion of acute PACG patients among hospitalized surgical glaucoma patients increased significantly after the COVID-19 outbreak, which is related to risk factors such as oral anti-cold medications containing vasoconstrictors or antihistamines, increased daily water intake, anxiety and other lifestyle, and mood changes.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
