【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).

【Objective】 To analyze the predictive value of serum β-defensin-3 (HBD-3) and decoy receptor 3 (DCR3) for urinary tract infection after percutaneous nephrolithotomy (PCNL) in patients with complex kidney calculi. 【Methods】 A prospective study was conducted on 112 patients treated with PCNL at our hospital during Jan.2020 and Dec.2022.The patients were divided into the non-infection group (52 cases) and infection group (60 cases).The general data, HBD-3 and DCR3 levels of the two groups were compared.Receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of C reactive protein (CRP), procalcitonin (PCT), HBD-3 and DCR3 levels for postoperative urinary tract infection. 【Results】 Compared with the non-infection group, the infection group had higher levels of HBD-3 [(0.77±0.08) ng/mL vs. (1.36±0.25) ng/mL, P=0.001] and DCR3 [(4.68±0.53) ng/mL vs.(13.21±0.28) ng/mL, P=0.001].Multivariate logistic regression showed that a history of urinary tract surgery, preoperative urinary tract infection, operation time, catheterization time, stone load, type of antibiotics, concomitant renal dysfunction, intraoperative channel type, CRP, PCT, HBD-3 and DCR3 were risk factors of postoperative urinary tract infection (P<0.05).The ROC curve showed that the accuracy of CRP, PCT, and CRP plus PCT were 70.54%, 72.32%, and 78.57%, respectively; the accuracy of HBD-3, DCR3, and HBD-3 plus DCR3 were 69.64%, 75.89%, and 86.61%, respectively. 【Conclusion】 Postoperative urinary tract infection in patients with complex kidney calculi is associated with multiple factors, especially high expression levels of HBD-3 and DCR3.Combined detection has high predictive value.

ObjectiveBy starting with the combination of Os Draconis， Bupleuri Radix， and Ostreae Concha， the role of mineral medicine Os Draconis in the combination of the Bupleuri Radix-containing tri-herbal medicines was preliminarily explored from the perspective of supramolecular system formation. Method① The appearance and Tyndall phenomenon of single decoction of Os Draconis， Bupleuri Radix， and Ostreae Concha， as well as co-decoction of Bupleuri Radix-Os Draconis， Bupleuri Radix-Os Draconis-Ostreae Concha， and Bupleuri Radix-Ostreae Concha were observed， and the average particle size， dispersion coefficient， and Zeta potential of suspension particles in each decoction were determined. The micromorphology of supramolecular structures was observed by scanning electron microscope （SEM）. ② The pH of different compatibility systems， liquid viscosity coefficient， liquid surface tension， freeze-dried powder yield rate， and other physical properties were determined， and the interaction of different compatibility systems was detected by infrared absorption spectroscopy （FTIR） and UV-visible spectrophotometry （UV-Vis）. ③ The composition and content difference of different compatible systems were determined by high-performance liquid chromatography （HPLC） and ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry （UPLC-Q-TOF-MS）. ResultCompared with the single decoction， the co-decoction had more obvious turbidity and Tyndall phenomenon. The particles in the co-decoction suspension were smaller and more evenly distributed， and the Zeta potential was reduced， indicating a more stable system. Under SEM， Bupleuri Radix was irregularly lamellar， and Bupleuri Radix-Os Draconis and Bupleuri Radix-Os Draconis-Ostreae Concha were mainly spherical nanoparticles. Bupleuri Radix-Ostreae Concha was irregularly lamellar， with a small number of spherical nanoparticles. The pH of the single decoction of Bupleuri Radix and co-decoction increased， and the viscosity coefficient increased. The liquid surface tension decreased. The freeze-dried powder yield rate of the Bupleuri Radix-Os Draconis co-decoction was the highest， followed by Bupleuri Radix-Ostreae Concha decoction and Bupleuri Radix-Os Draconis-Ostreae Concha decoction， and the yield rate of Bupleuri Radix single decoction was the lowest. The main change of FTIR was the stretching vibration of -OH， and the co-decoction moved to the low-frequency direction obviously. UV-Vis showed that the maximum absorption occurred at 295.8 nm for all groups， and the absorption intensity was different （Bupleuri Radix-Os Draconis>Bupleuri Radix-Os Draconis-Ostreae Concha>Bupleuri Radix-Ostreae Concha>Bupleuri Radix）. The components of Bupleuri Radix were used as the indexes， and the content of methanol extract determined by HPLC was higher than that of water extract， and the components of Bupleuri Radix single decoction were mainly saikosaponin a （SSa） and saikosaponin c （SSc）， which were slightly higher after co-decoction compatibility. UPLC-Q-TOF-MS could identify 37 compounds in both single decoction and co-decoction. ConclusionThe combination of Bupleuri Radix， Os Draconis， and Ostreae Concha can form a smaller， more uniform， and stable nano-sized supramolecular system， which is conducive to the dissolution of the main components of Bupleuri Radix， and the Os Draconis contributes the most in this process.

Objective:To systematically review thrombosis risk prediction models associated with peripherally inserted central venous catheter (PICC) in adults and provide a basis for the clinical application of these models and the development of subsequent models.Methods:Databases such as CNKI, Wanfang, VIP, PubMed, CINAHL, Web of Science, and Ovid were searched to collect studies on thrombosis risk prediction models related to adult PICC, covering all entries from the inception of the databases until December 31, 2022. Two researchers independently screened the literature, extracted data, and assessed the risk of bias.Results:Nineteen studies were included. D-dimer was the most common predictive factor; only five studies underwent external validation, and six studies evaluated model calibration. All included studies exhibited high risk of bias, primarily due to methodological deficiencies in model development and validation processes; the combined area under the receiver operating characteristic curve for nine models was 0.80 (95% Confidence Interval: 0.75-0.85) .Conclusions:Research on thrombosis risk prediction models related to adult PICC is still in its developmental stage. Most of the known models perform well with comprehensive and easily obtainable predictive factors, yet they exhibit methodological shortcomings. Future research should focus on improving the methodological quality and external validation during model development and validation processes.

Objective To explore the correlation between the expression of long non-coding RNA(lncRNA)brain ischemia-related factor(BIRF)and focally amplified lncRNA on chromosome 1(lncRNA FAL1)in serum and the degree of white matter lesions(WML)in patients with cerebral small vessel disease(CSVD).Methods From June 2021 to June 2023,102 CSVD patients admitted to Affiliated Hospital of Chengde Medical University were collected,and these patients were grouped into WML group(n=72)and non WML group(n=30)based on WML diagnostic criteria.According to the Fazekas score,the WML group was further grouped into mild WML group(n=24),moderate WML group(n=36)and severe WML group(n=12).Real-time fluorescence quantitative polymerase chain reaction(qRT-PCR)was applied to detect the levels of lncRNA BIRF and lncRNA FAL1 in serum.Pearson correlation was applied to analyze the correlation between serum lncRNA BIRF and lncRNA FAL1 levels.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum lncRNA BIRF and lncRNA FAL1 levels for severe WML in CSVD patients.Results The age(70.50±5.86 years),history of hypertension(Yes/No,43/29),history of diabetes(Yes/No,45/27),IL-33(68.35±6.80 pg/ml),IL-18(97.78±9.65 ng/L),ubiquitin carboxyl terminal hydrolase L1(UCH-L1)(0.29±0.10 μg/L)and lncRNA BIRF level(2.45±0.30)of patients in the WML group were higher than those in the non WML group(67.10±5.76 years,11/19,9/21,62.48±6.13 pg/ml,92.56±9.37 ng/L,0.24±0.06 μg/L,1.02±0.11),while the expression of serum lncRNA FAL1(0.52±0.10)was lower than that in the non WML group(1.04±0.15),with significant differences(t=2.683,4.518,8.978,4.085,2.510,2.550,25.346,20.500,all P<0.05).The serum lncRNA BIRF levels of CSVD patients in the mild,moderate and severe WML groups(2.23±0.23,2.47±0.31,2.82±0.42)were increased sequentially,while the expression of serum lncRNA FAL1(0.60±0.15,0.51±0.09,0.40±0.04)was decreased sequentially,with significant differences(F=14.913,13.899,all P<0.05).Pearson correlation analysis,the serum levels of lncRNA BIRF and lncRNA FAL1 in patients with WML were negatively correlated(r=-0.603,P<0.001),serum lncRNA BIRF was positively correlated with Fazekas score in WML patients(r=0.483,P<0.001),but serum lncRNA FAL1 was negatively correlated with Fazekas score(r=-0.507,P<0.001).The AUCs of serum lncRNA BIRF and lncRNA FAL1 levels alone and both combination for predicting severe WML in CSVD patients were 0.756(0.641～0.850),0.839(0.733～0.915)and 0.892(0.796～0.953),respectively,and the combination of the two was superior to the detection of serum lncRNA BIRF alone(Z=2.111,P=0.035).Conclusion The serum lncRNA BIRF level is increased and lncRNA FAL1 is reduced in patients with CSVD and WML,and both are related to the degree of WML in CSVD patients.

Objective To investigate the effect of erector spinae plane block on ultrasound-based hemodynamic parameters of the arteries of the four limbs and biochemical stress indicators in patients with thoracoscopic lobectomy. Methods A total of 120 patients with thoracoscopic lobectomy were randomly divided into study group and control group, with 60 cases in each group.The study group received erector spinae plane block during surgery, while the control group received conventional anesthesia measures.Pulmonary function indicators[peak expiratory flow rate (PEFR), forced vital capacity (FVC), forced expiratory volume in the first second (FEV₁)], ultrasound-based hemodynamic parameters of the arteries of the four limbs (maximum systolic velocity, minimum diastolic velocity, mean velocity, arterial pulsatility index, and arterial resistance index), stress indicators[cortisol (Cor), norepinephrine (NE), angiotensin Ⅱ(Ang Ⅱ), and adrenocorticotropic hormone (ACTH)], and analgesic effect were compared between the two groups at different time points[before anesthesia induction (T₀), after extubation (T₁), and after drainage tube removal (T₂)]. Results FEV₁, FVC and PEFR in both groups were significantly lower at T₁ and T₂ than at T₀, and FEV₁, FVC and PEFR in the study group were significantly higher than those in the control group at T₁ and T₂(P < 0.05).The maximum systolic velocity and arterial resistance index in both groups were significantly lower at T₁ and T₂ than at T₀, while the minimum diastolic velocity, mean velocity and arterial pulsatility index were significantly higher at T₁ and T₂ than at T₀(P < 0.05).The maximum systolic velocity and arterial resistance index in the study group were significantly higher than those in the control group at T₁ and T₂, but the minimum diastolic velocity, mean velocity and arterial pulsatility index were significantly lower than those in the control group (P < 0.05).Cor, ACTH, Ang Ⅱ and NE in both groups were significantly higher at T₂ than at T₀, and Cor, ACTH, Ang Ⅱ and NE in the study group were significantly lower than those in the control group at T₂(P < 0.05).The Prince-Henry pain score, effective compression times, and actual compression times in the study group were significantly lower than those in the control group (P < 0.05). Conclusion Application of erector spinae plane block in thoracoscopic lobectomy causes smaller fluctuations in hemodynamic parameters of the arteries of four limbs and biochemical stress indicators, with a better anesthetic effect.

With the improved understanding of driver mutations in non-small cell lung cancer (NSCLC), expanding the targeted therapeutic options improved the survival and safety. However, responses to these agents are commonly temporary and incomplete. Moreover, even patients with the same oncogenic driver gene can respond diversely to the same agent. Furthermore, the therapeutic role of immune-checkpoint inhibitors (ICIs) in oncogene-driven NSCLC remains unclear. Therefore, this review aimed to classify the management of NSCLC with driver mutations based on the gene subtype, concomitant mutation, and dynamic alternation. Then, we provide an overview of the resistant mechanism of target therapy occurring in targeted alternations ("target-dependent resistance") and in the parallel and downstream pathways ("target-independent resistance"). Thirdly, we discuss the effectiveness of ICIs for NSCLC with driver mutations and the combined therapeutic approaches that might reverse the immunosuppressive tumor immune microenvironment. Finally, we listed the emerging treatment strategies for the new oncogenic alternations, and proposed the perspective of NSCLC with driver mutations. This review will guide clinicians to design tailored treatments for NSCLC with driver mutations.
