OBJECTIVE To establish a method for simultaneous determination of 7 anti-tumor drugs (irinotecan, capecitabine, paclitaxel, docetaxel, tamoxifen, letrozole and methotrexate) in human plasma and apply it to the clinic. METHODS After precipitating with a methanol-acetonitrile mixture (1∶ 1, V/V) containing 0.1% formic acid, liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to determine the plasma concentration, using deuterium isotopes of each analyte as internal standards. The chromatography was performed on the Agilent Eclipse Plus C18 column with a gradient elution of water (containing 0.1% formic acid+0.04% 5 mmol/L ammonium formate) as mobile phase A and acetonitrile (containing 0.1% formic acid) as mobile phase B. The flow rate was 0.6 mL/min, and the column temperature was set at 40 ℃ . The sample size was 10 μL, and the analysis lasted for 5.5 min. Electrospray ionization was used in positive and negative ion mode, and multiple reaction monitoring mode was used. The ion pairs used for quantitative analysis were m/z 587.1→167.1 (irinotecan), m/z 360.1→244.1 (capecitabine), m/z 876.4→308.0 (paclitaxel), m/z 830.3→304.2 (docetaxel), m/z 372.1→129.1 (tamoxifen), m/z 284.1→242.1 (letrozole), and m/z 455.0→ 308.0 (methotrexate). A total of 97 patients with malignant tumors in our hospital were selected to measure the plasma concentrations of 7 anti-tumor drugs using the above method. RESULTS The linear ranges of irinotecan, capecitabine, paclitaxel, docetaxel, tamoxifen, letrozole and methotrexate were 2-1 000 ng/mL (r=0.994 3), 20-10 000 ng/mL (r=0.997 5), 2-1 000 ng/mL (r=0.997 9), 1-500 ng/mL (r=0.995 8), 1-500 ng/mL (r=0.995 2), 1-500 ng/mL (r=0.996 4), 10-5 000 (r=0.997 7), respectively. The quantitative lower limits were 2, 20, 2, 1, 1, 1 and 10 ng/mL; RSDs of intra-assay precision were 0.08%-14.86% (n=6). RSDs of inter-batch precision were 1.51%-11.55% (n=3), and the accuracies were 89.17%-114.93% (n=6). The matrix effects ranged from 89.89%-119.74% (n=6). RSDs of the stability tests were 1.98%-14.88% (n=6). The results of E-mail:hangpengzhou@163.com clinical application showed, the average plasma concentrations of irinotecan, capecitabine, paclitaxel and docetaxel were 704.09, 909.40, 36.45, 150.43 ng/mL, respectively. The values of the coefficient of variation were 25.24%, 62.65%, 122.69%, and 92.27%. CONCLUSIONS The established LC-MS/MS method is simple and rapid, and can be used for the simultaneous determination of 7 commonly used anti-tumor drugs in the plasma of patients with malignancy.

AIM:To investigate alterations in the expression levels of inflammatory cytokines and subsets of CD8+ T cells in the peripheral blood of patients with diabetic retinopathy(DR).METHODS:Retrospective study. A total of 40 patients with type 2 diabetes admitted to Xi'an People's Hospital(Xi'an Fourth Hospital)from April to July 2022 were recruited for this study and categorized into two groups: 20 cases in the simple type 2 diabetes mellitus(DM)group, and 20 cases in the DR group. Additionally, 20 healthy individuals undergoing routine physical examinations served as the control group. The expression levels of cytokines, including interleukin(IL)-6, IL-8, and IL-10 in peripheral blood were quantified using ELISA. Flow cytometry was employed to analyze the expression of programmed cell death-1(PD-1), T cell immunoglobulin domain and mucin domain protein-3(TIM-3), CD28, and CD57 on CD8+ T cells.RESULTS:The peripheral blood expression of IL-6, IL-8, and IL-10 inflammatory cytokines were significantly elevated in DR patients as detected by ELISA(all P<0.001); flow cytometry analysis showed that the expression of PD-1, TIM-3, and CD57 were elevated in peripheral blood CD8+ T cells of DR patients(all P<0.001), and the expression of CD28 was decreased(all P<0.001).CONCLUSION:In DR patients, CD8+ T cells may undergo depletion and senescence as a result of elevated pro-inflammatory cytokines, including IL-6, IL-8, and IL-10.

Stroke is a critical health issue in China, and carotid artery stenosis and plaque play key roles in its prevalence. Despite the acknowledged significance of this condition, detailed information regarding the prevalence of carotid artery stenosis and plaque across the Chinese population has been scarce. This study analyzed data from the China Stroke High-risk Population Screening and Intervention Program for 2020-2021, focusing on 194 878 Chinese adults aged 40 years and above. It assessed the prevalence of carotid artery stenosis and plaque and identified their associated risk factors. Results revealed a standardized prevalence of 0.40% for carotid artery stenosis and 36.27% for carotid plaque. Notably, the highest rates of stenosis were observed in north and south China at 0.61%, while southwestern China exhibited the highest plaque prevalence at 43.17%. Key risk factors included older age, male gender, hypertension, diabetes, stroke, smoking, and atrial fibrillation. This study highlights significant geographical and demographic disparities in the prevalence of these conditions, underlining the urgent need for targeted interventions and policy reforms. These measures are essential for reducing the incidence of stroke and improving patient outcomes, addressing this significant health challenge in China.

OBJECTIVE:
To explore the early changes in various liver function indicators in critically injured trauma patients assessed by intelligent calculation method, aiming to develop more advantageous diagnostic and treatment strategies for traumatic liver injury.
METHODS:
A retrospective study was conducted. Critically injured trauma patients [injury severity score (ISS) ≥ 16, age > 18 years old] admitted to the Emergency Medical Center of Tianjin Fifth Central Hospital from January 1, 2022, to December 1, 2023 were enrolled. ISS score and acute physiology and chronic health evaluation II (APACHE II) assessed by intelligent calculation method were collected upon patient admission to the emergency medical center. Trends in liver function indicators in fasting venous serum were analyzed at 6, 24 and 72 hours after admission, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-glutamyl transferase (GGT), lactate dehydrogenase (LDH), albumin (ALB), total bilirubin (TBil), prothrombin time (PT). Patients were grouped based on APACHE II scores into those with APACHE II < 15 and APACHE II ≤ 15, and liver function indicators within 6 hours of admission were compared between the two groups.
RESULTS:
A total of 112 critically injured trauma patients were included, with 83 males and 29 females, an average age of (47.78±14.84) years old. The median ISS score was 21.0 (18.0, 26.0). The most common cause of injury for critically injured trauma patients was road traffic accidents (68 cases, accounting for 60.71%), followed by falls from heights, compression injuries, heavy object injuries, knife stabs, and explosion injuries. The most common injured areas was the limbs and pelvis (97 cases, accounting for 86.61%), followed by chest injuries, surface skin and soft tissue injuries, abdominal and pelvic organ injuries, head injuries, and facial injuries. The proportion of elevated LDH, AST, and ALT within 6 hours of admission was 77.68%, 79.46%, and 52.68%, respectively, while the proportion of decreased ALB was 75.89%, the abnormal rates of ALP, GGT, TBil, and PT were all below 50%. The ALT and AST levels of patients at 24 hours and 72 hours after admission were significantly lower than those at 6 hours after admission [ALT (U/L): 37.0 (22.0, 66.0), 31.0 (21.2, 52.0) vs. 41.0 (25.0, 71.0), AST (U/L): 55.5 (30.0, 93.5), 40.0 (27.0, 63.2) vs. 69.5 (39.0, 130.8), all P < 0.05]. There was no statistically significant difference in ISS score between APACHE II > 15 group (45 cases) and APACHE II ≤ 15 group [67 cases; 21.0 (18.5, 26.5) vs. 20.0 (17.0, 22.0), P > 0.05]. Nevertheless, compared with patients with APACHE II ≤ 15, patients with APACHE II > 15 have a higher abnormality rate of ALT and AST within 6 hours of admission [ALT abnormal rate: 66.44% (29/45) vs. 44.78% (30/67), AST abnormal rate: 93.33% (42/45) vs. 70.15% (47/67), both P < 0.05], and the levels of ALT and AST were higher [ALT (U/L): 56.0 (30.0, 121.0) vs. 35.0 (21.0, 69.0), AST (U/L): 87.0 (48.0, 233.0) vs. 52.0 (31.0, 117.0), both P < 0.05].
CONCLUSIONS
Severe trauma patients frequently exhibit a high incidence of reversible early liver function impairment. Based on intelligent calculation method, the utilization of both the ISS and APACHE II scores demonstrates a distinct advantage in the assessment of their early liver injury.

ObjectiveSleep-related painful erections (SRPE) is a rare sleep disorder characterized by repeated awakening due to painful interruptions of penile erections during nighttime sleep, and its etiology is currently unclear. The purpose of this study is to explore the impact of potential risk factors on the incidence of SRPE. MethodsInformation was collected through questionnaires administered to patients who presented at the urology department and suffered from SRPE or did not suffer from SRPE. A total of 290 participants completed the study, including 145 controls and 145 cases. Logistic regression analysis was used to assess the impact of age, occupation, sleep initiation time per night, frequency of sexual intercourse per week, psychological status, erectile dysfunction, chronic prostatitis, prostate enlargement, lumbar spine disease, central nervous system disease, hypertension, diabetes and family history on the onset of SRPE. ResultsSingle-factor logistic regression analysis found that a history of chronic prostatitis, intellectual labor occupation, central nervous system disease, late sleep onset, frequency of sexual activity, and anxiety status might be related to the onset of SRPE. After incorporating these factors into a multivariate regression analysis model, it was found that having sexual activity ≥2 times/week (OR 95%CI = 0.326(0.179,0.592) and late sleep onset (after 24:00) (OR 95%CI = 0.494(0.265,0.918)might be protective factors for SRPE, while a history of chronic prostatitis(OR 95%CI = 3.779(2.082,6.859) might be a risk factor for SRPE. However, there was no significant statistical difference in the impact of central nervous system diseases and occupation on multivariate analysis. ConclusionChronic prostatitis and anxiety status may be independent risk factors for SRPE; having sexual activity ≥2 times/week and delaying sleep time appropriately may be independent protective factors.

Objective To understand the prevalence and risk factors of hyperuricemia in electronics factory workers in Wuhan, and to provide evidence for the health protection of electronics factory workers. Methods A total of 1 415 employees in an electronics factory in Wuhan were selected as the research subjects, and the physical examination and determination of various biochemical indicators, as well as questionnaire survey were carried out. Results The detection rate of hyperuricemia among workers in the electronics factory in Wuhan was 32.43%, with 36.33% for men and 14.11% for women, and the difference was statistically significant ( χ2=46.077,P<0.001). The detection rate of hyperuricemia was the highest (33.77%) among those with university or college education, followed by graduate students and above (31.50%). Compared with subjects with good lifestyle habits, people with drinking habits had higher hyperuricemia detection rate (49.38%), and the difference was statistically significant (P =0.001). The detection rates of hyperuricemia in those with central obesity and elevated alanine aminotransferase were 48.23% and 61.29%, respectively, which were significantly higher than those in the subjects without the above diseases (26.91% and 27.21%, respectively), and the differences were statistically significant (P <0.001). Obese people had the highest detection rate of hyperuricemia (66.95%), followed by overweight people (43.75%), and the difference was statistically significant (P <0.001). Multivariate logistic analysis showed that alcohol drinking (OR=1.836, 95% CI=1.139-2.961, P =0.013) and body mass index ≥ 24 kg/m2 (OR=2.175, 95% CI=1.686 -2.806, P <0.001) were risk factors for hyperuricemia in electronic factory workers. Elevated alanine aminotransferase (ALT) was significantly correlated with hyperuricemia (OR=2.964, 95%CI=2.146-4.095 , P <0.001). Female gender was a protective factor for hyperuricemia in workers in the electronics factory (OR=0.441, 95%CI=0.297-0.653 , P <0.001). Conclusion The detection rate of hyperuricemia among workers in an electronics factory in Wuhan is high, and the detection rate of hyperuricemia in men is higher than that in women. Alcohol consumption, overweight and obesity will increase the risk of hyperuricemia. Elevated ALT is associated with hyperuricemia. Maintaining an ideal body mass index and establishing a good lifestyle play an important role in preventing hyperuricemia.

Objective:To investigate the clinical characteristics of psoriasis and status quo of medical care for patients in county areas of China.Methods:This study was a cross-sectional investigation. Based on the “Qianxian Wuyin” Project (a national project for upgrating ability for psoriasis care at county level), an online questionnaire survey was conducted in the dermatology departments of 459 county hospitals in 404 pilot administrative counties across China from February to June 2023. The questionnaire included demographic information of patients (gender, ethnicity, age, place of residence, education, marital status), and clinical characteristics of psoriasis (disease course, type, comorbidities, body surface area (BSA) and previous treatment. The Dermatology Life Quality Index (DLQI) and Psoriasis Area and Severity Index (PASI) were applied for assessing the quality of life and disease severity, and completed by patients or guardian and doctors, respectively.Results:A total of 16 935 patients completed the questionnaire. The age of patients was 1-102(44.17±11.58)years, and 71.0% (12 036/16 935) were 30-59 years old. The ratio of male to female was 2.21∶1; 24.3%(4 117/16 935) of patients had high school education; there were 9 940 patients(58.7%) with previous or current smoking and/or alcohol use; 42.8%(7 218/16 855) of patients had a disease course of 1-5 years. There were 15 630 patients(92.3%) with DLQI≥10, 8 346 patients(49.7%) with PASI≥10, 15 017 patients(89.2%) with BSA≥10%. The plaque type was the most common disease type ( n=14 965, 88.7%), and spotting type ranked the second ( n=1 141, 6.8%). The most common initial site was the trunk ( n=12 309, 72.9%). Among the comorbidities, hypertension was the most common one ( n=1 681, 10.0%). There were 7 650 reports of treatment response to conventional topical drug therapy and 3 112 reports of treatment response to systemic drug therapy, with 6 269 (81.9%) and 2 493 (80.1%) reporting poor or no response, respectively. Conclusions:The survey shows that in the county areas of China, the majority of psoriasis patients are severe patients with short course of disease, plaque type is the most common type, and hypertension is the most common comorbidity; and the conventional treatment is less effective for most patients.

Objective:To analyze the clinical data and to screen the mortality risk factors of necrotizing fasciitis (NF) secondary to intestinal fistulas (NFsIF).Methods:This study was a retrospective observational study. The data of all NFsIF cases who met the inclusion criteria and were admitted into Shandong Provincial Hospital Affiliated to Shandong First Medical University (hereinafter referred to as our unit) from January 2000 to October 2023, and in PubMed, Web of Science, Scopus, China National Knowledge Infrastructure, and Chinese Medical Journal Network databases from its establishment to October 2023 were retrieved and screened. Based on clinical outcomes, the cases were divided into survival group (47 males and 24 females) and death group (16 males and 7 females), and the mortality rate was calculated. Clinical data of patients in the two groups including age, underlying diseases (most related to NF), symptom duration before presentation, white blood cell count, causes of NF, signs of peritonitis, scope of NF involvement, and intestinal management and wound management measures were compared and analyzed to screen the risk factors of death in 94 patients with NFsIF.Results:A total of 94 valid cases were collected, including 90 patients reported in the literature and 4 patients admitted to our unit, with the mortality rate of patients being 24.5% (23/94). Univariate analysis showed that there were no statistically significant differences in age, underlying diseases, symptom duration before presentation, white blood cell count, causes of NF, signs of peritonitis, scope of NF involvement between patients in the two groups ( P>0.05); there were statistically significant differences in intestinal treatment and wound treatment between the two groups (with χ2 values of 17.97 and 8.33, respectively, P<0.05). Multivariate logistic regression analysis showed that both intestinal treatment measures and wound treatments measures were independent risk factors for death in 94 NFsIF patients, among which first-stage colostomy+late-stage reconstruction and negative presssure therapy had higher protective effects (with odds ratios of 0.05 and 0.27, respectively, 95% confidence intervals of 0.01-0.33 and 0.08-0.88, respectively, P<0.05). Conclusions:The mortality risk of patients with NFsIF is high. Based on comprehensive treatments, active intestinal and wound treatment may be the key to avoid death, with first-stage colostomy+late-stage reconstruction and negative pressure therapy having higher protective effects.
