Objective To summarize the experience in the perioperative nursing of one-stage bilateral total hip arthroplaaty (THA) for the systemic lupus erythematosus (SLE) patients with avascular necrosis of the femoral head (ANFH).Methods From June 1998 to April 2007,17 cases of patients who were diagnosed as SLE with bilateral ANFH were treated by one-stage bilateral THA.Perioperative nursing included psychological support,diet control,observation and nursing of various complications,correct functional exercise and health education.Harris score and SF-36 score were evaluated before and after operation.Results There were 2 cases with delayed incision healing,1 with early prosthesis dislocation,1 with thigh pain for 10 months and 1 with acute renal failure postoperatively,which were improved and recovered after proper treatments.Asymptomatic deep vein thrombosis (DVT) in low extremities were detected by color Doppler ultrasonography in 6 cases.There were no pulmonary embolism and no deep infection around prosthesis.There was no Addisonian crisis postoperatively.The pain was relieved and the motion of joint was improved during follow-up.There was no radiological evidence of implant loosening.The Harris hip score and SF-36 score greatly alleviated after operation.All patients were followed up and the mean follow-up time was 28 months.Conclusions One-stage bilateral THA has good results for the patients with SLE and AVNH.Strengthening of perioperative nursing contributed to improvement of success rate of surgery and reduction of complication.

Objective To assess the noninvasive index for diagnosing the degree of esophageal varices (EV) in patients with hepatitis B virus (HBV)-related cirrhosis. Methods The clinical data of 112 patients with HBV-related cirrhosis were studied retrospectively. The patients were divided into non-EV (NEV) group (30 cases) and EV group (82 cases) according to the results of gastroscopy. In EV group, there were mild varices in 21 cases (mild EV group), moderate varices in 47 cases (moderate EV group) and severe varices in 14 cases (severe EV group). The age, gender, platelets, glutamyl transpeptidase, prothrombin time, albumin, bilirubin, portal vein diameter, spleen vein diameter and thickness of spleen were compared, and the relationship was analyzed between each index and EV. Results There were no statistical differences in gender, age, albumin, bilirubin, prothrombin time and glutamyl transpeptidase between NEV group and EV group (P>0.05). The portal vein diameter, spleen vein diameter and thickness of spleen in EV group were significantly higher than those in NEV group:(14.1 ± 3.1) mm vs. (10.6 ± 2.3) mm, (8.9 ± 2.1) mm vs. (7.6 ± 1.6) mm and (4.8 ± 0.9) mm vs. (3.8 ± 1.0) mm, the platelets in EV group was significantly lower than that in NEV group:(86.8 ± 20.2) × 109/L vs. (163.5 ± 18.1) × 109/L, and there were statistical differences (P<0.01 or<0.05). The portal vein diameter, spleen vein diameter and thickness of spleen in moderate EV group and severe EV group were significantly higher than those that in NEV group and mild EV group: (13.5 ± 2.1) and (14.8 ± 3.6) mm vs. (10.6 ± 2.3) and (11.2 ± 3.1) mm, (8.3 ± 2.1) and (9.1 ± 1.1) mm vs. (7.6 ± 1.6) and (8.1 ± 1.9) mm, (4.7 ± 1.1) and (4.9 ± 0.9) mm vs. (3.8 ± 1.0) and (4.1 ± 1.2) mm, the platelet levels were significantly lower than those in NEV group and mild EV group: (72.8 ± 11.6) × 109/L and (63.8 ± 15.6) × 109/L vs. (163.5 ± 18.1) × 109/L and (100.2 ± 10.3) × 109/L, and there were statistical differences (P<0.05). The area under curve of response operating characteristic for predicting the presence of moderate and severe EV with portal vein diameter and platelets were 0.719 and 0.735, and the cut off value were 14 mm and 69 × 109/L. Conclusions The portal vein diameter and platelets can predict the presence of moderate and severe EV in patients with HBV-related cirrhosis.

Objective:To evaluate the relationship between blood transfusion factors (massive transfusion, transfusion of stored red blood cells and anhepatic transfusion) and early postoperative outcomes in the patients undergoing orthotopic liver transplantation.Methods:Patients with end-stage liver disease who underwent orthotopic liver transplantation and intraoperative blood transfusion from January 2021 to March 2022 in our hospital were retrospectively selected, and their clinical data were collected. The patients were divided into massive transfusion group (M group, total red blood cell transfusion ≥10 U) and non-massive transfusion group (NM group) according to the amount of intraoperative blood transfused. The patients were divided into fresh blood group (NS group) and stored blood group (S group, red blood cell storage time > 2 weeks) according to the storage time of red blood cells transfused. The patients were divided into transfusion in anhepatic stage group (group T) and nontransfusion in anhepatic stage group (group NT) according to whether blood was transfused in the anhepatic stage. Multivariate logistic regression, generalized linear model and generalized linear mixed model were used to analyze the relationship between blood transfusion factors and primary outcome measures (postoperative pulmonary complications, circulation overload, acute kidney injury, abdominal infection, thrombosis) and between blood transfusion factors and secondary outcome measures (duration of ICU stay, postoperative hospitalization, postoperative temperature ≥38.5 ℃ at any time point after surgery, postoperative liver and kidney function index, coagulation function index, platelet count and preoperative difference).Results:One hundred and six patients were enrolled in this study. The results of multivariate logistic regression analysis: Massive blood transfusion and infusion of stored blood were risk factors for postoperative pulmonary complications, massive blood transfusion was a risk factor for abdominal infection, Child-Turcotte-Pugh score for liver function and time of anhepatic phase were risk factors for postoperative acute kidney injury, Child-Turcotte-Pugh score was a risk factor for circulatory overload, and age and massive blood transfusion were risk factors for thrombosis ( P<0.05). The results of generalized linear model analysis: Intraoperative stored blood transfusion and blood transfusion during the anhepatic phase were risk factors for prolonged duration of ICU stay, massive blood transfusion, intraoperative stored blood transfusion and blood transfusion during the anhepatic phase were risk factors for prolonged hospitalization ( P<0.05), and there was no correlation between massive blood transfusion, intraoperative stored blood transfusion and blood transfusion during the anhepatic phase and temperature ≥38.5 ℃ at any time point after surgery ( P>0.05). The results of generalized linear mixed model analysis: There was statistically significant difference in the difference between preoperative and postoperative liver and kidney function indexes, coagulation function indexes and platelet counts in the patients with or without massive transfusion, stored blood transfusion or blood transfusion during the anhepatic phase ( P<0.05). Conclusions:Massive blood transfusion and infusion of stored blood are the main risk factors for early adverse outcomes after orthotopic liver transplantation in the patients.

Objective:To investigate the risk factors and treatment outcome of recurrent Acanthamoeba keratitis (AK) after corneal transplantation. Methods:A serial case-observational study was carried out.Twenty-eight eyes of 28 patients with AK who underwent corneal transplantation in Shandong Eye Hospital from January 2012 to January 2019 were enrolled.All the eyes received corneal transplantation from failing to respond to topical and systemic anti- Acanthamoeba medical therapy, including 13 eyes that received penetrating keratoplasty (PKP) and 15 eyes that received lamellar keratoplasty (LKP). The corneal lesion was removed by a trephine with a diameter of 0.5 mm over infiltration area during PKP or LKP.The clinical features of recurrent AK were summarized, including recurrence time, site and signs, and the risk factors of AK recurrence were analyzed.Local and systemic anti- Acanthamoeba medical therapy was performed in all relapsed eyes, and secondary surgery was performed for the eyes with poor response to medication.The therapeutic outcome of recurrent AK was evaluated.The study adhered to the Declaration of Helsinki.This study protocol was approved by an Ethics Committee of Shandong Eye Hospital (No.201112). Results:In the 28 eyes, 7 eyes (25%) appeared recurrent AK after keratoplasty, including 2 eyes after PKP and 5 eyes after LKP.There was no significant difference in the recurrence rate between the two methods ( P=0.396). The recurrence rate of eyes that had used glucocorticoids drugs before operation was 57.14% (4/7), which was significantly higher in comparison with 14.29% (3/21) of eyes without glucocorticoids before surgery ( P=0.043). The recurrence rate of eyes with ulcer diameter ≥8.2 mm was 50.00% (5/10), which was significantly higher than 11.11% (2/18) of eyes with ulcer <8.2 mm ( P=0.036). The recurrent lesions began at the edge of implant bed accounted for 85.71% (6/7), and the recurrent lesions located below graft accounted for 14.29% (1/7). In 7 eyes with recurrent AK, 6 eyes were completely cured.Among recurrent AK eyes after LKP, 2 eyes were cured by long-term medical therapy, and 2 eyes were cured by extended-diameter LKP, and another 1 eye was cured by conjunctival flap covering surgery.One eye with recurrent AK after PKP was cured by extended-diameter PKP. Conclusions:The risk factors of recurrent AK after surgery are application of glucocorticoids before surgery and big lesions.Recurrent AK after surgery is curable by individualized therapy targeting to different clinical characteristics.

Objective To observe the hematological toxicity of 89SrCl2 in patients with multiple bone metastases of malignant tumors,and analyze the related-risk factors.Methods A total of 89 patients (63 males,26 females;age:(62.3±5.2) years) with multiple bone metastases and treated with 89SrCl2 were enrolled.Hematological data at 2 and 4 weeks after treatment with 89SrCl2 were analyzed.Common Terminology Criteria for Adverse Events (CTCAE) v4.03 was used to evaluate the hematological toxicity,and the influencing risk factors were analyzed.Logistic regression analysis was used to analyze the data.Results The incidences of grade Ⅰ-Ⅱ anemia,leukopenia and thrombocytopania at 2 and 4 weeks after treatment were 15.7％(14/89),18.0％(16/89),11.2％(10/89) and 18.0％(16/89),24.7％(22/89),18.0％(16/89),respectively.The incidences of grade Ⅲ-Ⅳ anemia,leukopenia and thrombocytopenia were 2.2％(2/89),0,0 and 2.2％(2/89),2.2％(2/89),3.4％％(3/89),respectively.Logistics multivariate analysis showed that the number of bone metastases and the Hb level before treatment were independent effect factors for hematological toxicity of 89SrCl2,with odds ratio (OR) values of 2.200(95％ CI:1.269-3.841) and 0.961 (95％ CI:0.932-0.991),respectively.Conclusions Serious hematological toxicity after 89SrCl2 treatment is rare.The number of bone metastases and the Hb level before treatment are independent effect factors for hematological toxicity.

Background: Chronic exposure to elevated levels of saturated fatty acids results in pancreatic β-cell senescence. However, targets and effective agents for preventing stearic acid-induced β-cell senescence are still lacking. Although melatonin administration can protect β-cells against lipotoxicity through anti-senescence processes, the precise underlying mechanisms still need to be explored. Therefore, we investigated the anti-senescence effect of melatonin on stearic acid-treated mouse β-cells and elucidated the possible role of microRNAs in this process. Methods: β-Cell senescence was identified by measuring the expression of senescence-related genes and senescence-associated β-galactosidase staining. Gain- and loss-of-function approaches were used to investigate the involvement of microRNAs in stearic acid-evoked β-cell senescence and dysfunction. Bioinformatics analyses and luciferase reporter activity assays were applied to predict the direct targets of microRNAs. Results: Long-term exposure to a high concentration of stearic acid-induced senescence and upregulated miR-146a-5p and miR- 8114 expression in both mouse islets and β-TC6 cell lines. Melatonin effectively suppressed this process and reduced the levels of these two miRNAs. A remarkable reversibility of stearic acid-induced β-cell senescence and dysfunction was observed after silencing miR-146a-5p and miR-8114. Moreover, V-maf musculoaponeurotic fibrosarcoma oncogene homolog A (Mafa) was verified as a direct target of miR-146a-5p and miR-8114. Melatonin also significantly ameliorated senescence and dysfunction in miR-146a-5pand miR-8114-transfected β-cells. Conclusion These data demonstrate that melatonin protects against stearic acid-induced β-cell senescence by inhibiting miR-146a- 5p and miR-8114 and upregulating Mafa expression. This not only provides novel targets for preventing stearic acid-induced β-cell dysfunction, but also points to melatonin as a promising drug to combat type 2 diabetes progression.

The current organ allocation rules prioritize elderly and urgent patients on the lung transplantation (LT) waiting list. A steady increase in the threshold at which age is taken into consideration for LT has been observed. This retrospective cohort study recruited 166 lung transplant recipients aged ≽ 65 years between January 2016 and October 2020 in the largest LT center in China. In the cohort, subgroups of patients aged 65-70 years (111 recipients, group 65-70) and ≽ 70 years (55 recipients, group ≽ 70) were included. Group D restrictive lung disease was the main indication of a lung transplant in recipients over 65 years. A significantly higher percentage of coronary artery stenosis was observed in the group ≽ 70 (30.9% vs. 14.4% in group 65-70, P = 0.014). ECMO bridging to LT was performed in 5.4% (group 65-70) and 7.3% (group ≽ 70) of patients. Kaplan-Meier estimates showed that recipients with cardiac abnormalities had a significantly increased risk of mortality. After adjusting for potential confounders, cardiac abnormality was shown to be independently associated with the increased risk of post-LT mortality (HR 6.37, P = 0.0060). Our result showed that LT can be performed in candidates with an advanced age and can provide life-extending benefits.
