【Objective】 To establish an effective quality indicator monitoring system, scientifically and objectively evaluate the quality management level of blood banks, and achieve continuous improvement of quality management in blood bank. 【Methods】 A quality monitoring indicator system that covers the whole process of blood collection and supply was established, the questionnaire of Quality Monitoring Indicators for Blood Collection and Supply Process with clear definition of indicators and calculation formulas was distributed to 17 blood banks in Shandong. Statistical analysis of 21 quality monitoring indicators in terms of blood donation service (10 indicators), blood component preparation (7 indicators ), and blood supply (4 indicators) from each blood bank from January to December 2022 were conducted using SPSS25.0 software The differences in quality monitoring indicators of blood banks of different scales were analyzed. 【Results】 The average values of quality monitoring indicators for blood donation service process of 17 blood banks were as follows: 44.66% (2 233/5 000) of regular donors proportion, 0.22% (11/50) of adverse reactions incidence, 0.46% (23/5 000) of non-standard whole blood collection rate, 0.052% (13/25 000) of missed HBsAg screening rate, 99.42% (4 971/5 000) of first, puncture successful rate, 86.49% (173/200) of double platelet collection rate, 66.50% (133/200) of 400 mL whole blood collection rate, 99.25% (397/400) of donor satisfaction rate, 82.68% (2 067/2 500) of use rate of whole blood collection bags with bypass system with sample tube, and 1 case of occupational exposure in blood collection.There was a strong positive correlation between the proportion of regular blood donors and the collection rate of 400 mL whole blood (P<0.05). The platelet collection rate, incidence of adverse reactions to blood donation, and non-standard whole blood collection rate in large blood banks were significantly lower than those in medium and small blood banks (P<0.05). The average quality monitoring indicators for blood component preparation process of 17 blood banks were as follows: the leakage rate of blood component preparation bags was 0.03% (3/10 000), the discarding rate of lipemic blood was 3.05% (61/2 000), the discarding rate of hemolysis blood was 0.13%(13/10 000). 0.06 case had labeling errors, 8 bags had blood catheter leaks, 2.76 bags had blood puncture/connection leaks, and 0.59 cases had non-conforming consumables. The discarding rate of hemolysis blood of large blood banks was significantly lower than that of medium and small blood banks (P<0.05), and the discarding rate of lipemic blood of large and medium blood banks was significantly lower than that of small blood banks (P<0.05). The average values of quality monitoring indicators for blood supply process of 17 blood banks were as follows: the discarding rate of expired blood was 0.023% (23/100 000), the leakage rate during storage and distribution was of 0.009%(9/100 000), the discarding rate of returned blood was 0.106% (53/50 000), the service satisfaction of hospitals was 99.16% (2 479/2 500). The leakage rate of blood components during storage and distribution was statistically different with that of blood component preparation bags between different blood banks (P<0.05). There were statistically significant differences in the proportion of regular blood donors, incidence of adverse reactions, non-standard whole blood collection rate, 400 mL whole blood collection rate, double platelet collection rate, the blood bag leakage rate during preparation process, the blood components leakage rate during storage and distribution as well as the discarding rate of lipemic blood, hemolysis blood, expired blood and returned blood among large, medium and small blood banks (all P<0.05). 【Conclusion】 The establishment of a quality monitoring indicator system for blood donation services, blood component preparation and blood supply processes in Shandong has good applicability, feasibility and effectiveness. It can objectively evaluate the quality management level, facilitate the continuous improvement of the quality management system, promote the homogenization of blood management in the province and lay the foundation for future comprehensive evaluation of blood banks.

Objective:To investigate the effects of selinexor,a inhibitor of nuclear export protein 1(XPO1)on the proliferation inhibition and apoptosis of Kasumi-1 cells in acute myeloid leukemia(AML).Methods:MTS method was used to detect the inhibitory effect of different concentrations of selinexor on the proliferation of Kasumi-1 cells at different time points.The apoptosis rate and cell cycle changes after treatment with different concentration of selinexor were detected by flow cytometry.Results:Selinexor inhibited the growth of Kasumi-1 cells at different time points in a concentration-dependent manner(r24 h=0.7592,r48 h=0.9456,and r72 h=0.9425).Selinexor inhibited Kasumi-1 cells growth in a time-dependent manner(r=0.9057 in 2.5 μmol/L group,r=0.9897 in 5 μmol/L group and r=0.9994 in 10 μmol/L group).Selinexor could induce apoptosis of Kasumi-1 cells in a dose-dependent manner(r=0.9732),and the apoptosis of Kasumi-1 cells was more obvious with the increase of drug concentration.The proportion of G0/G1 phase was significantly increased and the proportion of S phase was significantly decreased after the treatment of Kasumi-1 cells by selinexor.With the increase of drug concentration,the proportion of Kasumi-1 cells cycle arrest in G0/G1 phase was increased and the cell synthesis was decreased.Conclusion:Selinexor can promote the death of tumor cells by inhibiting Kasumi-1 cells proliferation,inducing apoptosis and blocking cell cycle.

Objective:To explore the surgical method and therapeutic effect of repairing soft tissue defect of digit-tip with single subcutaneous pedicle V-Y advancing flap combined with skin grafting.Methods:From August 2013 to December 2020, 25 soft tissue defects of digit-tip were repaired by a single subcutaneous pedicle V-Y advancing flap combined with pedicle skin grafting. The area of the defects was 0.8 cm× 0.8 cm to 1.6 cm× 1.4 cm. The flaps were harvested from palm or lateral side of the wound and the area of flap was 0.5 cm×1.0 cm to 0.8 cm×2.5 cm. In order to make the flap transfer to a further distance, the subcutaneous fibre connection of the flap was cut-off during the operation. At the same time, cut off 1 side of subcutaneous pedicle. Finally, the advanced distance of the flap reached 0.5-1.2 cm. After the flap harvested, the medium thickness skin was removed for graft to close the donor site from the wrist striations. After the surgery, follow-up visits were conducted regularly by outpatient clinic, or via telephone or WeChat review or by home visit. Throughout the follow-up, the flap appearance, sensation and recovery of the function of digital joint were observed, together with the patient satisfaction. Results:After the surgery, the postoperative follow-up lasted for 4 months to 8 years. All 25 flaps and skin grafts were survived in first stage wound healing. The flaps and skin grafting areas had excellent texture. The fingerprint had been reconstructed with good appearance. The TPD was 4-9 mm, the functions of digital joint recovered well, and there was no complain about a discomfort at the donor site. According to the evaluation standard of Michigan hand function questionnaire, all 25 patients were very satisfied with the overall appearance and function of the hand. According to Total Angle of Motion (TAM) evaluation standard, finger mobility was excellent in all 25 patients.Conclusion:Subcutaneous V-Y advancing flap combined with skin grafting is an ideal method for repairing soft tissue defect of digit-tip. The surgery characterises a simple flap cutting, less traumatic damage, long advancing distance of flap and good repair effect.

Objective:To investigate the relationship between cardiometabolic index and metabolic syndrome in people aged 40 and beyond in Guiyang city.Methods:A total of 4 506 residents over 40 years(including 3 067 females and 1 439 males) were enrolled in the analysis from those who participated in the epidemiological study of cancer risk in Chinese patients with type 2 diabetes in 2011 in Guiyang City. The cardiometabolic index (CMI) is calculated by triglycerides(TG)/high-density lipoprotein-cholesterol(HDL-C)×waist-to-height ratio (WHtR). Multivariable logistic regression was used to analyze the correlation between cardiometabolic index and metabolic syndrome, and ROC was used to analyze the predictive ability of CMI on the incidence of metabolic syndrome. Results:The average follow-up period was 3 years. According to the International Diabetes Federation (IDF) diagnostic criteria for metabolic syndrome in 2005, 985 patients (774 women and 211 males) had metabolic syndrome. The incidence rate of metabolic syndrome in the general population was 21.86%, the incidence rate of male metabolic syndrome was 14.66%, and that of women was 25.24%, and the incidence of CMI increased with the increase of the number of women. After multivariable logistic regression analysis, the odds ratio of CMI for metabolic syndrome in women is 1.303(95% CI 1.263-1.344) and 1.724(95% CI 1.162-2.558) in men, respectively. ROC results showed that CMI had a good ability to predict the incidence (AUC: 0.759 for men and 0.852 for women). Conclusion:CMI is positively associated with the incidence of metabolic syndrome. It supports CMI as a useful method to screen metabolic syndrome in China′s general population.

Objective:To explore the association of cardiometabolic index(CMI) and other body fat evaluation indicators [body mass index(BMI), waist circumference(WC), waist to height ratio(WHtR), lipid accumulation index(LAP)] with the prevalence of metabolic syndrome(MS) as well as the predictive value of the above indicators for MS.Methods:A total of 10 140 residents over 40 years old in Guiyang city who participated in the " Epidemiological study on tumor risk of type 2 diabetes patients in China" in 2011 were recruited. The 2005 International Diabetes Federation diagnostic criteria were used to identify MS. Logistic regression was used to analyze the association of CMI and other body fat evaluation indicators with MS. Receiver operating characteristic(ROC) curve was used to evaluate the predictive value and the optimal cut-off point of different indicators. Taking the best cut-off point value of each index as the boundary, the prevalence of MS was evaluated again by Chi square test.Results:The prevalence of MS in the study population was 39.81%(27.23% for men and 44.39% for women). Logistic regression analysis showed that the risk of MS increased with increasing CMI and quartile level of other body fat evaluation indicators in both men and women( P<0.05). The risks of MS in CMI Q4 group were 17.15(95% CI 11.64-25.27) for male and 45.14(95% CI 37.07-54.96) for female compared with Q1 group. In male, the area under curve(AUC) of MS by predicted CMI was 0.761(sensitivity 79.8%, specificity 63.2%, optimal cut-off point 0.71). WC displayed the highest value of AUC among the body fat evaluation indicators. In women, the AUC value of MS predicted by CMI was 0.831(sensitivity 76.8%, specificity 75.7%, optimal cut-off point 0.65), higher than those of BMI and WHtR while lower than those of WC and LAP. Further calculating the prevalence of MS with the best cut-off point value of each index as the boundary, WC was still the best predictor for male, while CMI was only secondary to LAP for women. Conclusion:CMI and other body fat evaluation indicators are significantly associated with MS. CMI could be used to predict MS.

Glycyrrhizic acid can regulate the expression and release of a variety of cytokines and play a significant anti-inflammatory effect. At the same time, glycyrrhizic acid also showed significant inhibition towards a variety types of viruses. Therefore, the potential application of glycyrrhizic acid as COVID-19 treatment should be explored.

Objective:To explore the surgical method and therapeutic effect of repairing digital tip defect with free flap of proximal perforating branch of proper palmar digital artery.Methods:From March, 2009 to January, 2021, 15 patients with soft tissue defects at the tip of 16 digits were repaired with free perforator flap of proper palmar digital artery. The flap was obtained from the ulnar side of an index finger, on both sides of a middle finger and on the proximal side of the radial side of the ring finger. The size of flaps was 1.8 cm × 1.2 cm - 4.5 cm × 2.2 cm. The flap carried dorsal branch of proper palmar digital nerve and 0.5-4.5 cm of arteriae digitales palmares propriae. The donor digital artery was re-anastomosed in 3 cases 3 digits, transferred and anastomosed in 2 cases and un-anastomosed in 10 cases 11 digits. The dorsal branch of the proper palmar digital nerve in the flap was anastomosed with the proper palmar digital nerve of the finger stump at the recipient site to restore the sensation of flap, and the donor sites at the wrist transverse stripes or elbow transverse stripes were directly sutured. Regular follow-up via outpatient visit, telephone or WeChat interviews was conducted to observe the appearance, sensation and recovery of the flap and finger joint function.Results:After surgery, the flaps and donor site skin grafts of 15 cases with 16 digits were all survived, with first stage healing. A 4 months to 12 years follow-up showed that the flaps were in good texture and full shape with TPD at 7 - 11 mm. The joint function of digits was recovered well, and there was no complaint about uncomfortable donor site. According to the Michigan Hand Function Questionnaire, all 15 patients were satisfied with the overall appearance and function of the hands. According to TAM evaluation standard, all the digits of 15 patients were in excellent.Conclusion:Free flap of the proximal perforating branch of proper palmar digital artery is an ideal in the repair of digital tip soft tissue defect, as it has the advantages of an anatomical constant vessel, hidden donor site, less trauma caused, simple flap resection and good therapeutic effect.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.
