ABSTRACT

In recent years, immunotherapy has made a breakthrough in the field of non-small cell lung cancer, reshaping the pattern of lung cancer treatment. However, with the wide application of immunotherapy in clinical practice, immune-related adverse events have attracted increasing attention. Immune pneumonia, as one of the immune-related toxic side effects of greatest concern, affects the treatment process and curative effect and can be a threat to life in serious cases. Given that immune pneumonia has a complicated pathogenesis and diverse clinical manifestations, strengthening the understanding of immune pneumonia is urgently needed. The treatment of immune pneumonia is limited, and additional therapeutic medicines are still awaiting exploration. Therefore, this paper summarizes the progress of the research on immune pneumonia in the treatment of non-small cell lung cancer.

ABSTRACT

Objective To compare the efficacy, safety, and survivability of TCbHP versus AC-THP in the neoadjuvant therapy of HER2-positive breast cancer in real-world. Methods Clinical data of patients with HER2 positive breast cancer, who have received TCbHP or AC-THP as neoadjuvant therapy and completed surgery in 11 third-class hospitals in various cities of Hebei Province, were retrospectively collected.The total pathological complete remission (tpCR) rate, the incidence of grade 3 or higher adverse reactions and the completion rate of the given approaches were compared. Results A total of 110 cases were collected, including 78 cases in the TCbHP group and 32 cases in the AC-THP group.The tpCR rate of the TCbHP group was higher than that of the AC-THP group, but the difference was not statistically significant (64.10% vs. 56.25%, P=0.441).No significant difference was found in the breast pathologic complete response (bpCR) and axillary pathologic complete response (apCR) rates between the TCbHP group and the AC-THP group (70.51% vs. 56.25%, P=0.150;78.21% vs. 84.38%, P=0.462).Exploratory analysis revealed that the tpCR rate of the TCbHP group was significantly higher than that of the AC-THP group in patients with HR-positive breast cancer (51.11% vs. 22.22%, P=0.036).As for the patients with HR-negative breast cancer, the tpCR rate of the AC-THP group tended to be higher than that of the TCbHP group (100% vs. 81.82%, P=0.088).The incidence of grade 3 or higher adverse reactions in the TCbHP group was slightly higher than that in the AC-THP group (12.82% vs. 9.38%, P=0.753).No deaths occurred in the whole group.Moreover, no significant difference was observed in the completion rate of the given approaches between the TCbHP group and the AC-THP group (92.31% vs. 90.63%, P=0.718). Conclusion In real-world clinical practice, the neoadjuvant therapy of TCbHP and AC-THP are effective, safe, and well tolerated among patients with HER2-positive breast cancer.The tpCR rate between the two approaches was not significantly different.The AC-THP regimen could also be considered as one of the optimal regimens for HER2-positive breast cancer in neoadjuvant therapy.

ABSTRACT

Malignant mesothelioma is a highly malignant disease that most often occurs in the pleural cavity, followed by the peritoneum and pericardium. Malignant peritoneal mesothelioma (MPM) accounts for 10%-15% of all mesothelioma. The most important risk factor for MPM is exposure to asbestos. MPM has no specific clinical symptoms, imaging and histopathology are critical for the diagnosis. There are currently no generally accepted guidelines for curative treatment of MPM. The patient mainly presented with abdominal pain, abdominal distension and discomfort. Due to extensive omentum metastasis, no further surgical treatment was performed. Pemetrexed combined with cisplatin chemotherapy was given for 2 cycles, and the patient is still alive.

ABSTRACT

Ultra-performance liquid chromatography-quadrupole time of fight/mass spectrometry(UPLC-Q-TOF-MS) and UNIFI were employed to rapidly determine the content of the components in Liangxue Tuizi Mixture. The targets of the active components and Henoch-Schönlein purpura(HSP) were obtained from SwissTargetPrediction, Online Mendelian Inheritance in Man(OMIM), and GeneCards. A "component-target-disease" network and a protein-protein interaction(PPI) network were constructed. Gene Ontology(GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were performed for the targets by Omishare. The interactions between the potential active components and the core targets were verified by molecular docking. Furthermore, rats were randomly assigned into a normal group, a model group, and low-, medium-, and high-dose Liangxue Tuizi Mixture groups. Non-targeted metabolomics was employed to screen the differential metabolites in the serum, analyze possible metabolic pathways, and construct the "component-target-differential metabolite" network. A total of 45 components of Liangxue Tuizi Mixture were identified, and 145 potential targets for the treatment of HSP were predicted. The main signaling pathways enriched included resistance to epidermal growth factor receptor tyrosine kinase inhibitors, phosphatidylinositol 3-kinase/protein kinase B(PI3K-AKT), and T cell receptor. The results of molecular docking showed that the active components in Liangxue Tuizi Mixture had strong binding ability with the key target proteins. A total of 13 differential metabolites in the serum were screened out, which shared 27 common targets with active components. The progression of HSP was related to metabolic abnormalities of glycerophospholipid and sphingolipid. The results indicate that the components in Liangxue Tuizi Mixture mainly treats HSP by regulating inflammation and immunity, providing a scientific basis for rational drug use in clinical practice.

ABSTRACT

The present study aimed to investigate the protective role of Shaofu Zhuyu Decoction(SFZY) against endometriosis fibrosis in mice, and decipher the underlying mechanism through the phosphatase and tensin homolog deleted on chromosome ten(PTEN)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR) pathway. Eighty-five BALB/c female mice were randomly assigned into a blank group, a model group, high-, medium, and low-dose SFZY(SFZY-H, SFZY-M, and SFZY-L, respectively) groups, and a gestrinone suspension(YT) group. The model of endometriosis was induced by intraperitoneal injection of uterine fragments. The mice in different groups were administrated with corresponding groups by gavage 14 days after modeling, and the blank group and model group with equal volume of distilled water by gavage. The treatment lasted for 14 days. The body weight, paw withdrawal latency caused by heat stimuli, and total weight of dissected ectopic focus were compared between different groups. The pathological changes of the ectopic tissue were observed via hematoxylin-eosin(HE) and Masson staining. Real-time PCR was employed to measure the mRNA levels of α-smooth muscle actin(α-SMA) and collagen type Ⅰ(collagen-Ⅰ) in the ectopic tissue. The protein levels of PTEN, Akt, mTOR, p-Akt, and p-mTOR in the ectopic tissue were determined by Western blot. Compared with the blank group, the modeling first decreased and then increased the body weight of mice, increased the total weight of ectopic focus, and shortened the paw withdrawal latency. Compared with the model group, SFZY and YT increased the body weight, prolonged the paw withdrawal latency, and decreased the weight of ectopic focus. Furthermore, the drug administration, especially SFZY-H and YT(P<0.01), recovered the pathological and reduced the area of collagen deposition. Compared with the blank group, the modeling up-regulated the mRNA levels of α-SMA and collagen-Ⅰ in the ectopic focus, and such up-regulation was attenuated after drug intervention, especially in the SFZY-H and YT groups(P<0.05,P<0.01). Compared with the blank group, the modeling down-regulated the protein level of PTEN and up-regulated the protein levels of Akt, mTOR, p-Akt, and p-mTOR(P<0.01, P<0.001). Drug administration, especially SFZY-H and YT, restored such changes(P<0.01). SFZY may significantly attenuate the focal fibrosis in the mouse model of endometriosis by regulating the PTEN/Akt/mTOR signaling pathway.

ABSTRACT

Objective:To investigate the efficacy of modified Mohs micrographic surgery in the treatment of eccrine porocarcinoma.Methods:Clinical data were collected from 5 patients with eccrine porocarcinoma, who treated with modified Mohs micrographic surgery in Department of Dermatology, Wuhan No.1 Hospital from 2016 to 2020, and retrospectively analyzed.Results:Among the 5 patients, 2 were males and 3 were females, their age ranged from 52 to 80 years, and the course of disease ranged from 1 to 50 years. Skin lesions were located on the scalp, face, abdomen, thighs and feet, with diameters ranging from 1 to 6 cm. Tumor excision was performed with 1-cm margins, and was deep to the superficial fascial layers. For histopathologically negative surgical margins, the defects were closed with skin flaps or grafts; for histopathologically positive margins, the excision margin continued to be widened until it was clean. The 5 patients were followed up for 1 - 5 years without recurrence, and 1 died 2 years later due to liver cancer metastasis.Conclusion:Modified Mohs micrographic surgery can ensure clean resection margins and reduce the loss of normal tissues in the treatment of eccrine porocarcinoma.

ABSTRACT

Objective:To explore the application value of ventricular intracranial pressure monitoring (V-ICPM) in the treatment of unilateral temporal lobe cerebral contusion.Methods:A retrospective cohort study was conducted to analyze the clinical data of 295 patients with unilateral temporal lobe cerebral contusion admitted to 904th Hospital of PLA Joint Support Force from January 2014 to August 2021, including 172 males and 123 females; aged 14-78 years [(46.3±14.7)years]. V-ICPM was used in 136 patients (V-ICPM group), who received surgical or non-surgical treatment according to the monitoring, while not in 159 patients (non-V-ICPM group), who received routine surgery or non-surgical treatment. The two groups were compared in terms of the rates of intracranial hematoma clearance by craniotomy, decompressive craniectomy (DC) and dehydration and osmotic therapy during hospitalization, use time of 20% mass fraction of mannitol and 30 g/L hypertonic salt, displacement rate of brain midline structure of head CT≥10 mm after discharge, rate of intracranial infection, hydrocephalus and epilepsy, and Glasgow Outcome Scale (GOS) at 6 months after discharge.Results:All patients were followed up for 6-12 months [(8.9±2.1)months]. During hospitalization, the rate of intracranial hematoma clearance by craniotomy and the rate of DC in V-ICPM group were 35.3% (48/136) and 8.1% (11/136), lower than 47.2% (75/159) and 22.0% (35/159) in non-V-ICPM group ( P<0.05 or 0.01). There was no significant difference between the two groups in the rate of dehydration and osmotic therapy or the use time of mannitol (all P>0.05). The use time of hypertonic salt in V-ICPM group was (7.2±2.5)days, more than (4.1±1.8)days in non-V-ICPM group ( P<0.05). After discharge, the displacement rate of brain midline structure of head CT in V-ICPM group was 29.4% (40/136), lower than 42.8% (68/159) in non-V-ICPM group ( P<0.05). There was no significant difference between the two groups in the rate of intracranial infection, hydrocephalus and epilepsy (all P>0.05). Six months after discharge, the good rate of GOS in V-ICPM group was 91.2% (124/136), significantly better than 81.8% (130/159) in non-V-ICPM group ( P<0.05). Conclusion:For unilateral temporal lobe cerebral contusion, V-ICPM is associated with reduced rate of craniotomy exploration and DC, decreased incidence of complications and improved prognosis of the patients in spite of longer use time of hypertonic salt.

ABSTRACT

Objective:To evaluate the application effect of the "group-based" teaching assistant (TA) guidance model in homogenized clinical skill training.Methods:A pilot study was conducted on the cardiopulmonary resuscitation training course, and 32 students majoring in clinical integrative Chinese and Western medicine (five-year program) who were admitted to Shanghai University of Traditional Chinese Medicine in 2018 were randomly divided into control group ( n = 16) and TA group ( n = 16). The control group received traditional teaching methods, and the TA group was further divided into subgroups A, B, C, and D, with four graduate TAs providing group-based teaching. The groups were compared in terms of their satisfaction and test scores. SPSS 25.0 was used for t-test and analysis of variance. Results:The satisfaction survey showed that compared with the control group, the TA group had significantly higher degree of satisfaction with the increased practical opportunities, clinical skill practical ability, learning effect, and overall satisfaction. The immediate test showed that there was no significant difference in test score between the TA group (85.19±2.93) points and the control group (82.75±4.52) points. The test 30 days later showed that the TA group (83.50±5.13) points had a significantly higher test score than the control group (74.68±3.87) points, and the control group had a significantly lower test score than that in the immediate test ( P <0.001); however, there was no significant difference in the TA group's score between the immediate test and the test 30 days later. Conclusion:The "group-based" TA guidance model has a good effect in homogenized clinical skill training, and has a stable long-term effect, with high student satisfaction.

ABSTRACT

Objective To construct a rapid prediction system to improve the accuracy and efficiency of evaluation of the consequences of nuclear accidents at a field scale. Methods Base on a diagnostic wind field model and Lagrangian particle diffusion, we established a rapid prediction method for wind field and pollutant dispersion around complex underlying surfaces within a field scale, in a way of visual discrimination of buildings and vegetation distribution. With data simulation and the use of a real urban field example, the simulated results were compared with wind tunnel test measurements and computational fluid dynamics results to study the influence of complex underlying surfaces on wind field and pollutant transport in the region. Results The rapid prediction system could clearly simulate the high-resolution wind field and pollutant concentration distribution of the region in about five minutes. It could interface with geographic information software and couple with a mesoscale weather prediction model. In terms of accuracy, the system performed well in wind field simulation, with the fractional deviations of wind speed and wind direction being 0.33 and −0.08, respectively. Concentration field simulation was greatly affected by the wind field, and the ratios of simulated concentrations to observed concentrations were between 0.05 and 3.4, except for a few low concentration points. Conclusion The rapid prediction system can effectively simulate the distribution characteristics of the flow field and improve calculation efficiency when ensuring calculation accuracy, which provides an important reference for emergency response to nuclear accidents.

ABSTRACT

Transanal total mesorectal resection (taTME) has come a long way since it was first used in the clinic in 2010.The learning curve of this procedure is long due to different surgical approaches, different perspectives and different anatomical positions. Many surgeons experience complications during this procedure. Although the advantages and problems of this procedure have been reported in much literature, the anatomy and operation methods of taTME introduced in literatures and training centers are too complicated, which makes many surgeons encounter difficulties in carrying out taTME surgery. According to the author's experience in learning and carrying out this operation, spatial expansion process of ultralow rectal cancer was divided into three stages. At each stage, according to different pulling forces, three different schemes of triangular stability mechanics model were adopted for separation. From point to line, from line to plane, the model can protect the safety of peripheral blood vessels and nerves while ensuring total mesorectal excision . This model simplifies the complex surgical process and is convenient for beginners to master taTME surgical separation skills.

ABSTRACT

Qualitative and quantitative analysis of 2-(2-phenylethyl) chromones in sodium chloride(NaCl)-treated suspension cells of Aquilaria sinensis was conducted by UPLC-Q-Exactive-MS and UPLC-QQQ-MS/MS. Both analyses were performed on a Waters T3 column(2.1 mm×50 mm, 1.8 μm) with 0.1% formic acid aqueous solution(A)-acetonitrile(B) as mobile phases at gradient elution. MS data were collected by electrospray ionization in positive ion mode. Forty-seven phenylethylchromones was identified from NaCl-treated suspension cell samples of A. sinensis using UPLC-Q-Exactive-MS, including 22 flindersia-type 2-(2-phenylethyl) chromones and their glycosides, 10 5,6,7,8-tetrahydro-2-(2-phenylethyl) chromones and 15 mono-epoxy or diepoxy-5,6,7,8-tetrahydro-2-(2-phenylethyl) chromones. Additionally, 25 phenylethylchromones were quantitated by UPLC-QQQ-MS/MS. Overall, the rapid and efficient qualitative and quantitative analysis of phenylethylchromones in NaCl-treated suspension cells of A. sinensis by two LC-MS techniques, provides an important reference for the yield of phenylethylchromones in Aquilariae Lignum Resinatum using in vitro culture and other biotechnologies.

ABSTRACT

According to the theory of 'Xingben Dazao' of Psoralea corylifolia Linn. (BL), the susceptible syndromes and biomarkers of liver injury caused by BL were searched. Rat models of kidney-yin deficiency syndrome (M_yin) and kidney-yang deficiency syndrome (M_yang) were established, and all animal experimental operations and welfare following the provisions of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Traditional Chinese Medicine (No. YFYDW2020017). The results showed that BL significantly decreased the body weight, water intake, and urine weight of M_yin rats and increase the organ indexes of the liver, testis, adrenal gland, and spleen and the expression of alanine aminotransferase (ALT). Meantime, BL significantly increased the urine weight of M_yang rats and decreased the expression of ALT and aspartate aminotransferase (AST). Hematoxylin and eosin (HE) staining showed that BL could aggravate inflammatory infiltration of hepatocytes in rats with M_yin and alleviate liver injury in rats with M_yang. Metabolomics identified 17 BL co-regulated significant differential metabolic markers in M_yin and M_yang rats. Among them, 8 metabolites such as glutamine, quinolinate, biliverdin, and lactosylceramide showed opposite trends, mainly involving cysteine and methionine metabolism, tyrosine metabolism, tryptophan metabolism, purine metabolism, sphingolipid metabolism, glycerol phospholipid metabolism, glutamine metabolism, and other pathways. M_yin/M_yang may be the susceptible constitution of BL for liver damage or protection, which may be related to the regulation of amino acid metabolism and sphingolipid metabolism. The study can provide some experimental data support for the safe and accurate use of BL in the clinical practice of traditional Chinese medicine.

ABSTRACT

ObjectiveTo investigate the neurological outcome of children with dance-associated spinal cord injury without radiographic abnormality (SCIWORA) and explore its related factors and predictive model. MethodsFrom July, 2012 to January, 2022, 75 children with dance-associated SCIWORA hospitalized in Beijing Bo'ai Hospital were divided into improved group (n = 14) and non-improved group (n = 61) according to the American Spinal Injury Association Impairment Scale (AIS) grade a year later, and the related factors were analyzed. ResultsAll patients were girls aged four to ten years. Most of them were complete spinal cord injuries (52/75, 69%). The time of injury to rehabilitation (OR = 0.926, P = 0.046, 95%CI 0.858 to 0.999), the existing tendon reflex (OR = 46.915,P = 0.012, 95%CI 2.333 to 943.616) and muscle tension (OR = 8.932,P = 0.044,95%CI 1.063~75.067) were correlated with the AIS grade improvement. The combination of time of injury to rehabilitation, tendon reflex and muscle tone existing may predict the improvement of AIS (AUC = 0.953, P < 0.001,95%CI 0.878 to 0.989), the sensitivity and specificity were 100% and 83.61%, respectively. ConclusionThe neurological outcome of children with dance-associated SCIWORA is poor. Rehabilitation training as soon as possible is beneficial to the neurological recovery. Tendon reflexe and muscle tone existing at admission are closely related to improvement of neurological outcome, which could be used as potential indicators.

ABSTRACT

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

ABSTRACT

OBJECTIVE@#To investigate the value of pre-treatment albumin/fibrinogen ratio (AFR) on the prognosis of patients with diffuse large B-cell lymphoma (DLBCL).@*METHODS@#The data of DLBCL patients in the Affiliated Hospital of North Sichuan Medical College from April 2014 to March 2021 were retrieved, and 111 newly diagnosed patients who completed at least 4 cycles of R-CHOP or R-CHOP-like chemotherapy with complete data were included in the study. The clinical, laboratory examination and follow-up data of the patients were collected, and the receiver operating characteristic curve (ROC) was drawn according to patients' AFR before treatment and the survival status at the end of the follow-up, which could be used to preliminarily evaluate the predictive value of AFR for disease progression and patients' survival outcome. Furthermore, the correlation of AFR with the clinical and laboratory characteristics, progression-free survival (PFS) and overall survival (OS) was analyzed, and finally, univariate and multivariate Cox proportional hazard regression models were used to analyze factors affecting PFS and OS of DLBCL patients.@*RESULTS@#The ROC curve indicated that AFR level had a moderate predictive value for PFS and OS in DLBCL patients, with the area under the curve (AUC) of 0.616 (P =0.039) and 0.666 (P =0.004), respectively, and the optimal cut-off values were both 9.06 for PFS and OS. Compared with high-AFR (≥9.06) group, the low-AFR (<9.06) group had a higher proportion of patients with Lugano III-IV stage ( P <0.001), elevated lactate dehydrogenase (P =0.007) and B symptoms (P =0.038). The interim analysis of response showed that the overall response rate (ORR) in the high-AFR group was 89.7%, which was significantly higher than 62.8% in the low-AFR group (P =0.001). With a median follow-up of 18.5 (3-77) months, the median PFS of the high-AFR group was not reached, which was significantly superior to 17 months of the low-AFR group (P =0.009). Similarly, the median OS of high-AFR group was not reached, either, which was significantly superior to 48 months of the low-AFR group (P < 0.001). In multivariate Cox regression analysis, AFR <9.06 was an independent risk factor both for PFS and OS (HR PFS=2.047, P =0.039; HR OS=4.854, P =0.001).@*CONCLUSION@#Pre-treatment AFR has a significant value for the prognosis evaluation in newly diagnosed DLBCL patients.

ABSTRACT

Objective:To explore the surgical strategy of coronary artery bypass grafting(CABG) for moderate ischemic mitral regurgitation(IMR), and to clarify the impact of mitral valve surgical intervention(MVS) on the long-term prognosis of such patients.Methods:The clinical data of 234 consecutive patients with moderate IMR who received CABG from January 2013 to December 2018 were retrospectively included, with 184 males and 50 females. The age ranged from 29 to 78 years, with a mean of(61.5 ± 8.7) years old. According to whether MVS was performed at the same time, they were divided into CABG group(108 cases, CABG alone) and CABG+ MVS group(126 cases, CABG+ MVS at the same time). The long-term cardiac events, all-cause deaths, major cardiovascular and cerebrovascular adverse events(MACCE) and other end events were followed up. A matching queue was established by propensity matching score for statistical analysis.Results:After propensity matching score, a matching queue was established, including 78 pairs of patients. Survival analysis showed that the incidence of long-term cardiac events and postoperative new onset atrial fibrillation in CABG+ MVS group was significantly higher( P<0.05). However, there was no significant difference between the two groups in all-cause mortality, cardiogenic mortality, and the incidence of MACCE events( P>0.05). Cox regression analysis showed that simultaneous CABG+ MVS was a risk factor for long-term cardiac events and new postoperative atrial fibrillation. The results of subgroup studies showed that for patients without tricuspid regurgitation before operation, left ventricular end diastolic diameter>55 mm, and left ventricular ejection fraction(LVEF) ≤0.55, the probability of cardiac events after MVS at the same time of CABG was higher( P<0.05). However, patients with no tricuspid regurgitation before operation, left ventricular end diastolic diameter>55 mm, LVEF≤0.55, and left atrial diameter≥40 mm had a higher probability of atrial fibrillation after MVS at the same time of CABG( P<0.05). Conclusion:CABG can improve left ventricular remodeling in patients with moderate IMR, whether MVS intervention is performed at the same time or not, and the long-term survival rate of both is similar. CABG+ MVS in the same period can maintain a low residual reflux, but the incidence of long-term cardiac events and arrhythmias is high. The longer-term prognosis needs to be further studied. The surgical strategy of such patients should be selected individually according to the specific situation and the surgical quality in medical centers.

ABSTRACT

OBJECTIVES@#To find a method to distinguish exogenous gamma-hydroxybutyrate (GHB) from endogenous GHB by establishing ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS) based on exosome for quantitative detection of GHB in the rat blood.@*METHODS@#Adult male SD rats were divided into 1 h, 5 h, 10 h administration group and control group. After 1 h, 5 h and 10 h of single precursor of GHB gamma-butyrolactone (GBL) intraperitoneal injection in administration groups, 5 mL blood was collected from the abdominal aorta. Meanwhile, the control group was given a same dose of normal saline, and 5 mL blood was collected at 1 h. Among the 5 mL blood, 0.5 mL was directly detected by HPLC-MS after pretreatment, and exosomes were extracted from the remaining blood by differential centrifugation and detected.@*RESULTS@#The concentration of GHB in the control group was (87.36±33.48) ng/mL, and the concentration with administration at 1 h, 5 h and 10 h was (110 400.00±1 766.35) ng/mL, (1 479.00±687.01) ng/mL and (133.60±12.17) ng/mL, respectively. The results of exosome detection showed that no peak GHB signal was detected in the control group and the 10 h administration group, and the concentrations of GHB at 1 h and 5 h administration groups were (91.47±33.44) ng/mL and (49.43±7.05) ng/mL, respectively.@*CONCLUSIONS@#GHB was detected in blood exosome by UPLC-MS, which indicated that exogenous GHB could be detected in plasma exosomes, while endogenous GHB could not be detected, suggesting that this method may be used as a basis to determine whether there is exogenous drug intake.

ABSTRACT

Objective  To analyze the prevalence and risk factors of hyperuricemia (HUA) in Shenyang City, and to provide evidence for the prevention and treatment of HUA in this region. Methods From January 2013 to December 2020, 98,327 subjects who underwent physical examination in Shengjing Hospital of China Medical University in Shenyang were selected. The detection rate of HUA was calculated, and the risk factors of HUA were analyzed by multivariate logistic regression analysis. Results From 2013 to 2020, the overall prevalence of HUA was 22.48%, 30.75% in males and 9.13% in females. The prevalence rate in the male was significantly higher than that in the female (P<0.05). Except for a slight decrease in 2015 and 2020, the total prevalence rate showed an increasing trend year by year. With the increase of age, the prevalence of HUA in males decreased, while in females, it decreased slightly from 40 to 59 years old and increased significantly after 60 years old. With the increase of BMI (Body Mass Index), the prevalence of HUA also increased, and the difference was statistically significant (P<0.05). Logistic regression analysis showed that male, body mass index, physical examination year, hypertension, hyperlipidemia, hyperglycemia, triglyceride, LDL-C, abnormal liver and renal function were positively correlated with HUA, while age and HDL-C were negatively correlated with HUA. Conclusion  HUA occurs mainly in male people among physical examination population in Shenyang. With the increase of BMI, HUA increases.
