ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan， excavate and analyze the key information of Xieqingwan， and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

Objective To investigate expression level and clinical application value of microRNA(miR)-494-3p and long non-coding RNA(LncRNA)MAGI2-antisense RNA 3(MAGI2-AS3)in urine exosomes of patients with bladder cancer.Methods A total of 105 bladder cancer patients admitted to Chongqing Liangjiang New Area People's Hospital from July 2021 to June 2023 were selected as the cancer group,and 101 patients with benign bladder diseases were as the benign group.Real-time fluorescence quantitative PCR(qRT-PCR)was applied to detect miR-494-3p and LncRNA MAGI2-AS3 levels in urine exosomes.Kappa test was used to analyze the consistency among miR-494-3p,LncRNA MAGI2-AS3 in urinary exosomes and pathological biopsy diagnosis of bladder cancer.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of miR-494-3p and LncRNA MAGI2-AS3 levels in urinary exosomes for bladder cancer.Results The level of miR-494-3p(1.41±0.32)in the urine exosomes of the cancer group was higher than that of the benign group(1.02±0.24),while the level of LncRNA MAGI2-AS3[(0.79±0.19)vs(1.05±0.22)]was lower than that of the benign group(1.05±0.22),and the differences were statistically significant(t=9.866,9.089,all P＜0.05).The proportions of tumor diameter＞3 cm,T3～T4 stage,and lymph node metastasis in the high expression group of miR-494-3p were higher than those in the low expression group,and the differences were significant(x2=5.806,6.999,8.289,all P＜0.05).The proportions of T3～T4 stages and lymph node metastasis in the low expression group of LncRNA MAGI2-AS3 were higher than those in the high expression group,and the differences were significant(x2=9.244,7.795,all P＜0.05).MiR-494-3p and LncRNA MAGI2-AS3 in urine exosomes combined with pathological biopsy showed high consistency in the diagnosis of bladder cancer(Kappa value=0.718,P＜0.05).ROC curve showed that the areas under the curve(95％confidence interval)[AUC(95％CI)]of miR-494-3p and LncRNA MAGI2-AS3 levels in urinary exosomes alone for diagnosis of bladder cancer were 0.812(0.752～0.863)and 0.779(0.716～0.833),respectively.MiR-494-3p and LncRNA MAGI2-AS3 levels in urinary exosomes combined to diagnose the AUC(95％CI)of bladder cancer 0.877(0.824～0.918)were higher than that of AUC(95％CI)diagnosed separately(Z=2.053,2.647,P=0.040,0.008).Conclusion The level of miR-494-3p in urine exosomes of patients with bladder cancer was increased,while the level of LncRNA MAGI2-AS3 was decreased.The combination of the two may have high diagnostic value for bladder cancer.

Objective:To investigate the predictive value of neutrophil/lymphocyte ratio (NLR) at admission for stroke associated pneumonia (SAP) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the First Affiliated Hospital of Kunming Medical University from January 2019 to June 2020 were retrospectively included. The demographic information, vascular risk factors, severity of stroke at admission, and NLR data of the patients were collected. Multivariate logistic regression was used to analyze the independent correlation between NLR and SAP. The NLR was divided into quartile groups to further analyze the trend relationship between NLR and SAP. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of NLR for SAP. Results:A total of 316 patients with AIS were enrolled, including 200 males (63.29%) with an age of 63.86±13.78 years. The median baseline Nationanl Institutes of Health Stroke Scale score was 4 (interquartile range, 2-9), and the median NLR was 4.42 (interquartile range, 3.17-6.70). Ninety-three patients (29.43%) experienced SAP. Multivariate logistic regression analysis showed that NLR was an independent risk factor for SAP in patients with AIS (odds ratio 1.189, 95% confidence interval 1.077-1.313; P<0.001). Moreover, SAP risk increases with the increase of NLR ( Ptrend<0.001). Compared to the first quartile, the risk of SAP increased 9.991 times in the fourth quartile (95% confidence interval 2.912-34.279; P<0.001). ROC curve analysis showed that the area under the curve of NLR for SAP prediction was 0.793 (95% confidence interval 0.737-0.850), with an optimal cutoff value of 5.475. The sensitivity and specificity for predicting SAP were 66.67% and 79.82%, respectively. Conclusion:NLR at admission is an independent risk factor for SAP in patients with AIS and has certain predictive value for SAP.

Objective:To examine the clinical value of rapid detection of drug-resistant bacteria by immunochromatography and the effects of rapid detection on the prognosis of patients with severe intra-abdominal infection complicated by carbapenem-resistant Enterobacteriaceae (CRE) bloodstream infection.Methods:This was a retrospective cohort study. We analyzed clinical data of 73 patients with severe abdominal infections with sepsis or septic shock complicated by CRE bloodstream infection admitted to the general surgery department of Jinling Hospital between February 2022 and February 2023. Patients were divided into a colloidal gold immunochromatographic assay (GICA) group (17 patients) and conventional testing group (56 patients) based on whether a GICA for CRE had been performed on the patients' first blood culture sample during the diagnosis and treatment process. There were no statistically significant differences between the GICA and conventional testing groups in age ([55.9±17.3] vs. [47.6±16.4] years), sex ([16 men vs. one woman ] vs. [41 men vs. 15 women]), median Charlson comorbidity index (3.0[2.0,4.0] vs. 3.0[2.0, 4.8]), septic shock (10 vs. 39), or acute kidney injury (8 vs. 40) (all P>0.05). Both groups routinely underwent traditional bacterial identification and drug susceptibility testing. Additionally, patients in the GICA group were tested directly for positive blood cultures using a GICA carbapenemase test kit. The main outcomes were mortality rates on Days 28 and 90 after the first identification of CRE bloodstream infection in both groups. We also compared the microbial clearance rate, duration of hospitalization and intensive care unit stay, and time from onset of CRE bloodstream infection to initiation of targeted and appropriate antibiotics between the two groups. Results:The rate of microbial clearance of bloodstream infection was significantly greater in the GICA group than in the conventional testing group (15/17 vs. 34/56 [60.7%], χ 2=4.476, P=0.034), whereas the 28-day mortality tended to be lower in the GICA than conventional testing group [5/17 vs. 44.6% [25/56], χ 2=1.250, P=0.264). The 90-day mortality (8/17 vs. 53.6% [30/56], χ 2=0.222, P=0.638), median duration of hospitalization (37.0 [18.0, 46.5] days vs. 45.5 [32.2, 64.8] days, Z=-1.867, P=0.062), and median duration of intensive care unit stay (18.0 [6.5, 35.0] days vs. 32.0 [5.0, 51.8] days, Z=-1.251, P=0.209). The median time between the onset of bloodstream infection and administration of antibiotics was 49.0 (38.0, 69.0) hours in the GICA group, which is significantly shorter than the 163.0 (111.8, 190.0) hours in the conventional testing group ( Z=-5.731, P<0.001). The median time between the onset of bloodstream infection and administration of appropriate antibiotics was 40.0 (34.0, 80.0) hours in the GICA group, which is shorter than in the conventional testing group (68.0 [38.2, 118.8]) hours; however, this difference is not statistically significant ( Z=-1.686, P=0.093). Conclusions:GICA can provide information on carbapenemase- producing pathogens faster than traditional drug sensitivity testing, enabling early administration of the optimal antibiotics. The strategy of 'carbapenemase detection first' for managing bacterial infection has the potential to improve prognosis of patients and reduce mortality rate.

Methods: Experimental study was conducted from August 2020 to January 2022. Eight Bama minipigs underwent VVB of hepatic portal vein-femoral vein-internal jugular vein after occlusion of hepatic portal vein and inferior vena cava. The animals were divided into two groups according to the VVB devices used during VVB. A self-made VVB device was used in group A(n=5),and an imported VVB device was used in group B(n=3). The hemodynamic changes of the two groups of animals were compared at 6 time points including before vascular occlusion, during vascular occlusion, 30 minutes, 60 minutes, 90 minutes after the start of VVB, and 30 minutes after vascular opening. In addition,the changes of blood compatibility indexes,intestinal injury indexes,kidney injury indexes and internal environment indexes of the two groups of animals at each time point were compared. The independent samples t test was used for the quantitative data between the two groups with non-repeated measures,and the repeated measures analysis of variance was used for the quantitative data between the two groups with repeated measures. Results: During the VVB of the two devices,the venous drainage was sufficient,and the main manifestations were that the color of the intestine of the Bama miniature pig was ruddy, the peristalsis was normal, and the urine output was normal. There were no significant differences in hemodynamics,blood injure indexes,intestinal injury indexes,kidney injury indexes,neutropil gelatinase-associated lipocalin,and internal environment indexes(all P>0.05).The indexes at 30 minutes after vascular opening in the group A and the group B were as follows:mean arterial pressure were (71.0±7.7)mmHg(1 mmHg=0.133 kPa) and (74.0±8.7)mmHg,central venous pressure were (7.0±1.4)cmH₂O(1 cmH₂O=0.098 kPa) and (7.7±0.6)cmH₂O,heart rate were (131±10) beats/minutes and (132±8)beats/minutes; red blood cell count were (6.43±0.89)×10¹²/L and (6.32±0.58)×10¹²/L,hemoglobin were (108.4±5.9)g/L and (110.0±3.5)g/L,free hemoglobin were (78.28±3.96)mg/L and (78.08±4.54)mg/L; intestinal fatty acid binding protein were (2.27±0.49)μg/L and (2.40±0.78)μg/L;creatinine were (68.30±9.77)μmol/L and (79.90±26.91)μmol/L,blood urea nitrogen were (3.94±1.39)mmol/L and (3.45±0.65)mmol/L;neutropil gelatinase-associated lipocalin were (4.02±0.53) μg/L and (3.86±0.23)μg/L;pH value were 7.27±0.04 and 7.23±0.03,lactic acid were (6.18±2.62)mmol/L and (4.30±0.50)mmol/L,concentrations of Na⁺ were (136.3±3.0)mmol/L and (137.6±1.6) mmol/L,concentrations of K⁺ were (3.89±0.42) mmol/L and (3.98±0.17)mmol/L,concentrations of Ca²⁺ were (1.40±0.03)mmol/L and(1.40±0.04)mmol/L;all indexes in the two group had no differences(all P>0.05).

Objective:To investigate the correlation between serum ceruloplasmin level and elevated impulsivity in elderly patients with Parkinson′s disease (PD).Methods:227 elderly PD patients treated in Jinhua People′s Hospital from October 2019 to June 2021 were selected as the research objects. They were grouped according to the 75th percentile of serum ceruloplasmin. 0-75th percentile was defined as normal and >75th percentile was defined as high level. The differences of second-order and first-order factor scores of Barratt′s Impulsivity Scale Version 11 (BIS-11) between the two groups were observed. After balancing the general characteristics, the third part of Parkinson′s Disease Rating Scale (MDS-UPDRS), Hoehn&Yahr Scale, Addenbrooke Cognitive Examination Revised Edition (ACE-R), clinical treatment plan and other data, the correlation between ceruloplasmin and BIS-11 was observed.Results:According to the 75th percentile level of ceruloplasmin, 56 patients were included in the high-level group and 171 patients were included in the normal group. The level of ceruloplasmin, the ratio of female patients, MDS-UPDRS Ⅲ, Hoehn&Yahr Scale and ACE-R score in the high-level group were significantly higher than those in the normal group (all P<0.05). The second-order unplanned and corresponding first-order self-control and first-order self-knowledge complexity in the high-level group were higher than those in the normal group (all P<0.05). There was no significant difference in second-order attention, first-order attention, first-order cognitive instability, second-order motivation, first-order motivation, first-order stability and BIS-11 score between the two groups (all P>0.05). After removing the confounding factors by multifactor logistic analysis, ceruloplasmin was correlated with second-order unplanned and its corresponding first-order factors (self-control and self-knowledge complexity) (all P<0.05). Conclusions:The serum ceruloplasmin level in elderly PD patients is related to the elevated level of BIS-11 unplanned impulse.

Abstract: Objective　To understand the general situation of death causes of permanent residents in Hainan Province from 2014 to 2020, analyze the causes of death, and provide scientific basis for the formulation of policies related to healthy Hainan. Methods The Hainan Provincial Population Death Information Registration and Management System was used to report data, and the death information of permanent residents in Hainan Province from 2014 to 2020 was obtained. Excel 2010 and SPSS 26.0 software were applied to perform statistical analysis related to the indicators including crude mortality rate, standardized mortality rate, ranking of causes of death, and composition ratio; the standardized mortality rate was calculated based on the data of the 2010 National Census Data. Results　From 2014 to 2020, the average annual resident population of Hainan Province was 9 175 300, and average annual resident population at each of the eight monitoringp oints is 297 100， anaverage of 83 878 cumulative deaths were reported, the annual total mortality rate was 504.09/100 000, the standard mortality rate was 618.69/100 000. The standardized mortality rates of male and female were 806.18/100 000 and 444.36/100 000 respectively (P<0.01). The mortality rate of all age groups showed that the crude mortality rate of 0~<1 years old group showed a decreasing trend with the passage of time, and the crude mortality rate was significantly higher than that of other age groups. From the age of 20, with the increase of age, the overall crude mortality rate of residents keeps increasing. The crude death rate increases rapidly after the age of 65, and peaks especially after the age of 85. The leading causes of death were circulatory diseases, tumors and respiratory diseases. From 2014 to 2020, the mortality rate of circulatory diseases and tumors, the two main causes of death, was more than 100/100 000. Conclusion　Chronic non-communicable diseases are still the first cause of death among permanent residents in Hainan Province. Targeted intervention and treatment of chronic non-communicable diseases is beneficial to reduce their mortality.

Sempervirine, a yohimbane-type alkaloid isolated from Gelsemium elegans, was found to significantly inhibit the cellular proliferation of U251 cells in vitro and in vivo in a dose-dependent manner. U251 cells were treated with 0-16 μmol·L^-1 of sempervirine for 24, 48 or 72 h. An MTT assay and clone formation assay were used to investigate cell survival and clone formation. Hoechst staining and Annexin V-FITC/PI staining were used to measure cell apoptosis. The expression of PI3K, AKT, p-AKT, Bax, Bcl-2, caspase-3 and cleaved caspase-3 was determined by Western blot analysis. The antitumor effect of sempervirine in vivo was investigated by inoculating nude mice with U251 cells. All animal experiments were in strict accordance with the regulations of the Biomedical Ethics Committee of Fujian Medical University (Fujian, China). The results show that sempervirine significantly inhibits the proliferation and induces the apoptosis of U251 cells, promotes cleavage of caspase-3, down-regulates the protein expression of PI3K and Bcl-2/Bax, and inhibits phosphorylation of AKT in vitro. Intraperitoneal injection of 4 or 8 mg·kg^-1·day^-1 of sempervirine inhibits U251 cells tumor growth in the xenograft nude mice, and tumor weight decreased by 44.76% and 61.26%, respectively. Our study shows that sempervirine significantly inhibits the proliferation of U251 cells in vitro and in vivo, laying a foundation for further research and development of its anti-glioma effect.

Objective::On the basis of previous research, to detect the changes of six main alkaloids in Gelsemium elegans rhizomes before and after being processed, so as to reveal its internal mechanism of processing. Method::The contents of gelsemine, humantenidine, koumine, gelsenicine, gelsevirine and humantenine in G. elegans rhizomes was determined simultaneously by HPLC, the content changes of these components before and after processing and its reasons were analyzed by cluster analysis and principal component analysis. The mobile phase was methanol (A)-0.1%formic acid aqueous solution (B) for gradient elution (0-10 min, 22%A; 10-20 min, 22%-30%A; 20-30 min, 30%-40%A). The flow rate was 1.0 mL·min^-1. The detection wavelength was set at 254 nm, the injection volume was 10 μL, and the column temperature was 30 ℃. Result::Before processing, contents of the above six components in raw products were 1.444, 1.129, 3.590, 1.603, 2.376, 1.631 mg·g^-1, after processing, the contents of these six components were 2.258, 0.343, 1.176, 0.115, 0.459, 0.281 mg·g^-1, respectively. Gelsenicine, the most toxic ingredient of G. elegans rhizomes, decreased most significantly with a decreasing rate of 92.83%, while the less toxic ingredient, gelsemine, increased by 56.37%after processing. The contents of other four components in G. elegans rhizomes decreased to varying degrees after processing. The results of cluster analysis indicated that G. elegans rhizomes were clearly divided into two categories before and after processing. Principal component analysis showed that the first principal component before and after processing was changed from koumine to gelsemine. Conclusion::The degradation of toxic components and content changes of other components may be one of the intrinsic mechanism of toxicity attenuation and efficacy reservation of G. elegans rhizomes being processed.
