This article provides a review of domestic and international research on nursing-sensitive quality indicators (NSQIs) and evaluation systems for acute poisoning patients. It organizes the indicators into three dimensions based on the "structure-process-outcome" framework. The need for establishing a unified, comprehensive, and nationally suitable system of NSQIs in China is emphasized to standardize nursing practices and improve the monitoring of care quality. Although existing indicators possess some scientific validity, they often overlap with emergency nursing quality evaluation systems or are limited to specific types of poisoning. In addition, large-scale clinical trials to test their practical application and accessibility have yet to be conducted. This review aims to consolidate and analyze NSQIs for acute poisoning patients and provide a foundation and reference for improving the quality of nursing care for these patients.

In order to meet the market demand for the fast and accurate genetic detection of African swine fever virus(ASFV),a new method for EIS-qPCR detection was established with a rapid,high sensitivity,and pollution prevention.Primers and probes for a duplex qPCR were designed based on the conserved region of ASFV virus p72 gene and the endogenous internal standard(EIS)cytb gene sequence in pigs.An anti-contamination system was established with uracil DNA N-gly-cosylase enzyme in the reaction system.The results showed that the method can finish the rapid qPCR detection of ASFV within 30 min with a minimal detection limit of 4.12 copies/μL.Moreo-ver,the method only detected the ASFV p72 gene,and no amplifications of classical swine fever vi-rus(CSFV),pseudorabies virus(PRV),porcine parvo virus(PPV),porcine reproductive and re-spiratory syndrome virus(PRRSV)and porcine circovirus type 2(PCV2)were observed.Repeti-tive results showed a coefficient of variation below 2％.With strong anti-pollution capacity,the method can effectively eliminate false-positive amplification caused by low-dose aerosol pollution.Detection results of 146 clinical samples showed a 100％consistence with the results of the com-mercial ASFV detection kit.Compared with similar technologies,the EIS-qPCR established in this study was faster,sensitive,and suitable for the rapid diagnosis of ASFV infection in the early stage,which provided the tool for the monitoring and precise prevention and control of African swine fever.

Objectives:Fenofibric acid is extracted from the widely used hypolipemic fenofibrate,nowadays being approved for marketing around numerous nations and regions,nonetheless not in China.Present trial evaluated the efficacy and safety in the Chinese hypertriglyceridemia population. Methods:This is a multi-center,randomized,double-blind,placebo-controlled phase Ⅲ clinical trial.Patients from 3 different cohorts,including severe hypertriglyceridemia(HTG),moderate HTG and mixed-dyslipidemia(MD),were randomized at 1:1 ratio to receive fenofibric acid 135 mg or placebo daily for 12 weeks.The primary endpoint was the percentage change of triglyceridemia(TG)from baseline at week 12.Secondary endpoints were the percentage changes of other blood lipid indexes.At the same time,the incidence of medical adverse events was observed. Results:Among the three cohorts of patients with severe HTG(n=52),moderate HTG(n=23)and MD(n=52),the TG levels in the fenofibric acid-treated group decreased by(49.12±29.19)%,(49.95±25.19)%and(49.79±19.28)%,respectively from baseline to 12 weeks,while the corresponding placebo groups decreased by(18.88±40.69)%,(8.11±29.86)%and increased by(10.42±73.04)%,respectively from baseline to 12 weeks.The differences between treatment and placebo groups were statistically significant(P<0.017 for severe HTG cohort,P<0.05 for moderate and MD cohort).The high-density lipoprotein cholesterol(HDL-C)in the fenofibric acid-treated group increased by(25.51±21.45)%,(24.55±24.73)%,and(23.60±27.38)%,and the placebo group increased by(1.91±20.42)%,(2.40±9.32)%and(7.13±19.12)%,respectively,the differences between the two groups were statistically significant(all P<0.05).In the fenofibric acid group,adverse events with incidence>5%included upper respiratory tract infection(10.9%),abdominal pain(6.3%),and increased serum creatinine levels(6.3%),rates of adverse events were similar between the two groups(P>0.05). Conclusions:Fenofibric acid can significantly reduce triglycerides and elevate HDL-C levels safely in Chinese patients with severe to moderate HTG without statin or MD patients on top of statin therapy.

Objective To establish a more scientific and reasonable evaluation method for the heat resistance,freezing resistance,and thermal stability of glass containers for pharmaceutical packaging to meet the regulatory needs of drugs in the new situation.Methods A survey was conducted on domestic injection production enterprises in the form of a questionnaire,including the process parameters of cleaning for glass containers for pharmaceutical packaging,terminal sterilization during injection production,and the freeze-drying process flow of freeze-dried formulations.Results The parameters of dry heat sterilization,freeze-drying,and moist heat sterilization used in actual production of injections vary widely,and evaluation through laboratory simulation under single conditions lacks scientific and practical applicability.Conclusions In order to implement the construction of the new standard system for glass packaging materials in 2025 edition of the Chinese Pharmacopoeia,through this investigation,the actual production process parameters of drugs were shown,and it is proposed that specific experimental conditions for heat resistance,freezing resistance,and thermal stability will no longer be limited in the new standard system for use.Suitable experimental conditions can be set by enterprises based on their actual process to evaluate performance.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Acute myeloid leukemia (AML) is a disease caused by abnormal cloning of hematopoietic stem cells in the bone marrow, which leads to accumulation of a large number of abnormally differentiated myeloid cells. It is difficult to cure by traditional treatment. The successful application of chimeric antigen receptor T cell (CAR-T) immunotherapy indicates that the treatment of hematological tumors has entered a new stage of precision immunotherapy. However, CAR-T immunotherapy has been found to have many problems in clinical applications, including long treatment cycle, expensive prices, off-target effects, cytokine release syndrome, etc. Therefore, it is necessary to expand the application of CAR or adopt improved measures to enhance the therapeutic effect. This article reviews the new strategies for genetic engineering modification of CAR immune cells and the research progress and application of in situ programming to generate CAR-T, and besides, briefly introduces the new methods about the delivery of gene drugs in vivo, aiming to provide new ideas and theoretical basis for expanding and improving the application of precision immunotherapy in AML.

Objective:To identify and analyze the genuine medicinal plant Gentiana scabra Bge. from 9 regions in Liaoning Province using DNA barcode technology based on the base sequence of internal transcribed spacer. Methods:DNA was extracted from the medicinal parts of 26 Gentiana scabra Bge. samples by using DNA kit extraction method. The ITS sequence was amplified through polymerase chain reaction (PCR), and then two-way sequencing was carried out. Other sources and outgroup sequences of the medicinal plant Gentiana scabra Bge. were downloaded from Genbank. After the sequencing results were spliced by using SeqMan 7.1.0 software, MEGA 7.0 software was used to analyze and compare the data, and calculate the genetic distance of K2P (Kimura 2-parameter). The phylogenetic tree was established by Neighbor-Joining (NJ) method for analysis. Results:According to the results of NJ cluster tree, all Gentiana scabra Bge. samples from different sources were clustered into one large branch, and Gentiana scabra Franch. and Gentiana triflora Pall. were clustered into one branch respectively, with obvious differences; Gentiana scabra and Gentiana manshurica Kitag. were clustered into one branch, and the genetic relationship was relatively close. In combination with the variation site and genetic distance, the base sequences of Gentiana scabra and Gentianamanshurica were very similar, and the interspecific differences were very small. Except for the intraspecific variation of only one sample collected in Liaoning Province, the base sequences of the other samples were the same, and there was no difference between " Gentiana scabra Bge. in Qingyuan" and Gentiana scabra Bge. samples from other regions in Liaoning Province. Conclusion:The DNA barcode technology of ITS sequence can be used to differentiate and identify medicinal plant Gentiana scabra Bge. and its original plants from different sources with a high success rate.

Objective:To use rbcL sequences to identify the rhizomes of the Liaoning collection of Atractylodes chinensis (DC.) Koidz.; To provide a basis for ensuring the feasibility of cultivation of the native herb in Liaoning Province. Methods:A total of 30 rhizomes of Atractylodes chinensis (DC.) Koidz. were collected from 10 regions cultivated in Liaoning Province, and the total DNA was extracted. DNA barcodes were screened by PCR, and the rbcL sequences of the samples were amplified and sequenced, and the amplification and sequencing success rates were calculated. Sequence alignment was performed using MEGA 7.0 software; a systematic clustering tree was constructed using the neighbour-joining method. Results:The success rates of DNA extraction from the rhizomes of Atractylodes chinensis (DC.) Koidz. were all 93.3%, and the success rates of PCR amplification and sequencing were all 100%. Among the 30 samples of Atractylodes chinensis (DC.) Koidz. in Liaoning Province, two samples had intraspecific variation, and the rest of the base sequences of Atractylodes chinensis (DC.) Koidz. were identical. Atractylodes chinensis (DC.) Koidz. was closer to the herbs of the genus Cangzhu, a relative species of Asteraceae, and was genetically more distant from the rest of Asteraceae. The NJ tree could distinguish Atractylodes chinensis (DC.) Koidz. and its relatives. Conclusion:The quality of Atractylodes chinensis (DC.) Koidz. cultivars in Liaoning Province is basically similar, and the rbcL sequence can be used as a valid sequence fragment for the identification of Atractylodes chinensis (DC.) Koidz. DNA barcode.

Objective:To evaluate the correlation between ultrasound parameters of internal carotid artery blood flow and regional cerebral oxygen saturation (rScO 2) in elderly patients undergoing coronary artery bypass grafting (CABG) under cardiopulmonary bypass (CPB). Methods:Sixty-four elderly patients undergoing elective CABG under CPB, aged 60-80 yr, regardless of gender, with body mass index of 18.1-28.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, with New York Heart Association class Ⅱ or Ⅲ, with left ventricular ejection fraction≥50%, were selected. The rScO 2 and ultrasonic parameters of internal carotid artery including peak systolic velocity (PSV-ICA), end-diastolic velocity (EDV-ICA), diameter (D-ICA) and blood flow volume (Q-ICA) were recorded before anesthesia induction (T 0), at surgical skin incision (T 1), at 30 and 60 min of CPB (mean value was calculated, T 2), and at 30 and 60 min after termination of CPB (mean value was calculated, T 3). The ratio of unilateral internal carotid artery blood flow to cardiac output (Q/CO) was calculated. The receiver operating characteristic curve was used to analyze the accuracy of ultrasound parameters of internal carotid artery blood flow in predicting rScO 2 < 60%. Results:PSV-ICA was positively correlated with rScO 2 at T 0, T 1 and T 3 ( P<0.05), but no correlation was found between PSV-ICA and rScO 2 at T 2 ( P>0.05). There was no correlation between EDV-ICA and rScO 2 at each time point ( P>0.05). Q-ICA was positively correlated with rScO 2 at each time point ( P<0.05). Q/CO was not correlated with rScO 2 at T 1 ( P>0.05), but Q/CO was positively correlated with rScO 2 at T 2 and T 3 ( P<0.05). During the non-CPB period (T 0, T 1, T 3), the cutoff values of PSV-ICA and Q-ICA in predicting rScO 2< 60% were 51.35 cm/s and 283.5 ml/min respectively, the sensitivity was 0.900 and 0.900 respectively, and the specificity was 0.610 and 0.857 respectively (AUC=0.761, P=0.006; AUC=0.903, P< 0.001). During the CPB period, the cutoff values of Q-ICA and Q/CO in predicting rScO 2<60% were 296.5 ml/min and 5.84% respectively, the sensitivity was 0.900 and 0.800, and the specificity was 0.545 and 0.659 (AUC=0.764, P=0.001; AUC=0.748, P=0.002), respectively. Conclusions:PSV-ICA and Q-ICA are positively correlated with rScO 2 during the non-CPB period, and Q-ICA and Q/CO are positively correlated with rScO 2 during the CPB period in elderly patients undergoing CABG. PSV-ICA, Q-ICA and Q/CO can accurately predict rScO 2<60%.

Objective:To evaluate the efficacy and safety of Burosumab in patients with X-linked hypophosphatemic rickets.Methods:Clinical data of 9 children diagnosed with X-linked hypophosphatemic rickets and treated with Burosumab in the Department of Pediatric Nephrology, Anhui Children′s Hospital from November 2021 to September 2023 were retrospectively analyzed, including the general information, clinical manifestations, auxiliary examination, Burosumab treatment and follow-up.Results:Among the 9 cases, there were 5 males and 4 females, with a median age at diagonosis of 2 years. After traditional treatment, the fluctuation of serum phosphorus ranged from 0.7 to 0.9 mmol/L. The median age at the initiation of Burosumab treatment was 2.8 years, and the initial dosage was 0.8 mg/kg, administrated subcutaneously every 2 weeks. The laboratory and imaging indexes were improved after 6 months of Burosumab treatment, and the mean serum phosphorus level increased from(0.81±0.14) mmol/L to(1.02±0.10) mmol/L at 1 month( t=3.85, P=0.001) and(1.14±0.25) mmol/L at 6 months( t=3.58, P=0.002). The average alkaline phosphatase(ALP) level decreased from(509.89±110.10) U/L before treatment to(447.89±106.76) U/L after 1 month( t=1.21, P=0.243). After 6 months, the ALP level significantly decreased to(385.89±60.33) U/L ( t=2.96, P=0.009). The average height percentile increased from 18.42±10.09 before treatment to 26.56±16.59 after 6 months( t=1.26, P=0.227). Rachitis severity scores of both lower limbs ranged from 4.61±1.36 before treatment to 3.06±1.51 after 6 months( t=2.29, P=0.036). No serious adverse events occurred during treatment. Conclusion:Burosumab is safe and effective in treating X-linked hypophosphatemic rickets, exhibiting minimal side effects and significant clinical applicability value.
