ObjectiveThrough qualitatively and quantitatively analysis of the differences in chemical composition between the combined decoction and single decoction of Huaganjian and comparison of their core efficacy, to explore the rationality of the flexible clinical application of Huaganjian compound preparations and single-flavored dispensing granules. MethodsUltra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS) was used to qualitatively analyze the combined decoction and single decoction samples of Huaganjian, and meanwhile, the contents of four index components(geniposide, paeoniflorin, hesperidin and paeonol) were quantitatively analyzed by high performance liquid chromatography(HPLC). Nonalcoholic fatty liver disease(NAFLD) rat model induced by high-fat diet was applied to compare the efficacy of combined decoction and single decoction of Huaganjian. A total of 30 male SD rats were randomly divided into the control group, model group, lovastatin group(1.8 mg·kg-1), combined decoction group(1.26 g·kg-1) and single decoction group(1.18 g·kg-1). After successful modeling, lovastatin group, combined decoction group and single decoction group were given corresponding doses of drugs by intragastric administration every day, and the control group and model group were given equal amounts of normal saline by intragastric administration, after 4 weeks of administration, the serum and liver tissues were collected, and the contents of alanine aminotransferase(ALT), aspartate aminotransferase(AST), total cholesterol(TC), triglyceride(TG), low-density lipoprotein cholesterol(LDL-C) and high-density lipoprotein cholesterol(HDL-C) in serum of rats were detected, and the liver pathological examination was carried out by hematoxylin-eosin(HE) staining and oil red O staining, so as to compare differences of their efficacy. ResultsSeventy chemical components were initially identified and attributed from the lyophilized powder of the combined decoction and single decoction samples of Huaganjian, and there was no obvious difference in composition between the two. Further quantitative analysis showed that the contents of geniposide, paeoniflorin, hesperidin and paeonol in the combined decoction samples were significantly increased when compared with those of the single decoction samples(P<0.01). The pharmacodynamic results showed that compared with the model group, both the combined and single decoction groups of Huaganjian could improve the liver index of NAFLD rats, reduce the serum levels of AST, ALT, TC, TG and LDL-C, increase the serum level of HDL-C, and ameliorate the pathological changes of liver cell steatosis and fat accumulation. However, there was no significant difference in pharmacodynamic effects between the combined decoction group and the single decoction group. ConclusionThere is no significant difference between the combined decoction and single decoction of Huaganjian in terms of chemical composition, but the contents of the four index components show significantly difference. Both of them can significantly improve the fat accumulation and liver function in NAFLD rats. This study provides a reference basis for the rational clinical application and evaluation of famous classical formula compound preparations and single-flavored dispensing granules.

Objective To conduct a retrospective analysis of the correlation among bedaquiline(BDQ)plasma concentrations,relevant clinical factors,and disease prognosis.Methods In this retrospective study,22 patients diagnosed with rifampicin-resistant tuberculosis(RR-TB),multidrug-resistant tuberculosis(MDR-TB),or pre-extensively drug-resistant tuberculosis(pre-XDR-TB)were enrolled.These patients were admitted to the tuberculosis ward of our hospital between February 2022 and October 2024.All patients were administered a treatment regimen containing BDQ.The cohort comprised 6 RR-TB patients(27.27%),12 MDR-TB patients(54.55%),and 4 pre-XDR-TB patients(18.18%).Peripheral blood samples were collected 2 hours after the oral administration of Bedaquiline.The plasma concentration of Bedaquiline was measured using liquid chromatography-tandem mass spectrometry(LC-MS/MS).Spearman correlation analysis was performed using R studio software with the ggplot2 and corrplot packages.The factors included the blood concentration of bedaquiline,electrocardiogram QTcF(QT interval corrected by the Fridericia method),liver and kidney function parameters,weight,age,body mass index,sex,blood uric acid level,serum creatinine level,and other relevant indicators.Results In 22 patients treated with BDQ,the plasma concentration reached a peak after 1.5 weeks of administration,and gradually stabilized after 2 weeks.The plasma concentration was approximately 1-3 μg/mL.After 24 weeks of withdrawal of bedaquiline,patients were continued to monitor their bedaquiline concentration and found that BDQ blood concentration in peripheral blood was approximate 1 μg/mL up to 36 weeks.The serum concentration of BDQ was not correlated with age,body weight,BMI,ALT,AST,GGT,TDiL,urea,uric acid and QT interval,but correlated with sputum negative transformation and serum creatinine.The correlation analysis between serum concentration of BDQ and acid-fast staining of sputum smear showed,the difference was significant(r=0.35,P<0.05).In addition,the correlation analysis between serum BDQ concentration and serum creatinine showed,the difference was significant(r=0.34,P<0.05).The results of multiple linear regression analysis showed that BDQ blood concentration was positively correlated with Scr level,and Scr was an independent factor affecting BDQ blood concentration.20 cases(90.9%,20/22)were cured,1 case died of Covid-19 virus infection,1 case was recurrence.Conclusions Regimens containing bedaquiline seem to exhibit relatively high safety profiles and good tolerability among patients with rifampicin-resistant,multidrug-resistant,or pre-extensively drug-resistant tuberculosis,typically yielding favorable treatment outcomes.The BDQ shows a positive correlation with serum creatinine(SCr).Consequently,close surveillance of BDQ levels and renal function remains of utmost importance throughout the treatment course.

Objective:To analyze the relationship among self-efficacy, family support and diabetes self-management behavior in rural patients with type 2 diabetes mellitus, and to explore the mediating role of self-efficacy between self-management behavior and family support in rural patients with type 2 diabetes mellitus.Methods:From June to July 2023, Jingde county in southern Anhui, Jinzhai county in central Anhui, and Mengcheng county in northern Anhui were selected by multistage stratified cluster random sampling method as investigation sites. A total of 258 patients with type 2 diabetes mellitus were investigated by face-to-face survey. The questionnaire included general situation survey from, the summary of diabetes self-care activities measure, the self-efficacy for diabetes and diabetes family behavior checklist. SPSS 25.0 and AMOS 26.0 softwares were used for descriptive analysis, correlation analysis, common method bias test and mediation analysis.Results:The self-management behavior score of rural patients with type 2 diabetes mellitus was(2.15±0.96).The self-efficacy score was(28.50±7.02).The family support score was(29.37±9.45).Self-efficacy and family support were positively correlated with self-management behavior( r=0.390, 0.333, both P<0.01), and family support was positively correlated with self-efficacy( r=0.511, P<0.01). Self-efficacy played a partial mediating role between self-management behavior and family support in rural patients with type 2 diabetes, and the mediating effect accounted for 45.2%(0.147/0.325) of the total effect. Conclusion:Family support not only has direct influence on self-management behavior of rural patients with diabetes mellitus, but also has indirect influence on self-management behavior by improving self-efficacy.

Objective:To investigate the efficacy, safety and possible mechanisms of celecoxib as an adjunctive treatment for schizophrenia.Methods:90 schizophrenic inpatients at the second affiliated hospital of Xinxiang Medical College from April 2019 to October 2020 were recruited and randomly assigned to a placebo group or the celecoxib adjunctive treatment group using a random number table. In the placebo group, 46 patients (29 males, 17 females; aged 21-34, mean age 27.46±6.50 years) completed a 6-week follow-up. In the celecoxib group, 44 patients (32 males, 12 females; aged 21-39, mean age 30.52±8.69 years) completed a 6-week follow-up. The Positive and Negative Syndrome Scale (PANSS) was used to assess psychiatric symptoms in both groups. Changes in PANSS score at the end of the treatment were compared to evaluate the efficacy of celecoxib. Metabolic indicators such as weight, body mass index, waist circumference and plasm glucolipid, as well as cardiovascular indicators like blood pressure, electrocardiogram and routine blood tests, and adverse events were collected for the safety evaluation. Serum tumor necrosis factor-α (TNF-α), Interleukin-4 (IL-4) and interferon-γ (IFN-γ) were also tested. Pearson correlation analysis was used to explore the relationship between cytokine levels, PANSS score, PANSS reduction rate [(pre-treatment score-post-treatment score)/pre-treatment score×100%], and the safety measurements in the two groups, analyzing the role of inflammation in celecoxib adjunctive therapy.Results:The change of PANSS positive score at the end of the 6th week was significantly higher in the celecoxib adjuvant treatment group than in the placebo group (-8.00±6.12 vs -4.78±5.19, H=-0.55, P=0.009). The weight changes, body mass index, total cholesterol, and triglycerides over 6 weeks were significantly lower in the celecoxib group compared to the placebo group ( F=-7.37, -7.30, 2.56, -2.54; all P<0.05). No serious adverse events were found in celecoxib adjuvant therapy. In the placebo group, baseline TNF-α levels were positively correlated with baseline negative symptoms and PANSS reduction rate ( r=0.260 and 0.330, both P<0.05), and negatively correlated with the 6-week weight ( r=-0.311, P<0.05); baseline IL-4 levels were positively correlated with the 6-week PANSS total score and the 6-week PANSS negative score ( r=0.320 and 0.397, both P<0.05), and negatively correlated with PANSS reduction rate and 6-week blood glucose ( r=-0.316 and -0.331, both P<0.05); Six-week IFN-γ levels were negatively correlated with low-density lipoprotein levels ( r=-0.306, P<0.05). And no such correlation was found in celecoxib adjuvant group. Conclusion:Celecoxib adjunctive therapy can improve positive symptoms of schizophrenia without causing adverse reactions. Inflammatory state is related to schizophrenia symptoms, treatment efficacy and metabolic abnormalities.

Objective:To analyze the results of low-dose lung CT screening for military flying personnel, and to explore its influence on aeromedical identification.Methods:The imaging and aeromedical identification data of military flying personnel who underwent annual physical examination in Air Force Healthcare Center for Special Services Hangzhou were analyzed retrospectively. According to the imaging manifestations, the enrolled low-dose lung CT results were divided into the following 6 categories: no obvious abnormality, old lesions, pulmonary nodules, pulmonary bullae, pulmonary inflammatory lesions and extrapulmonary diseases. The detection rates of various examination results were statistically analyzed. The military flying personnel were divided into 20-29 years group, 30-39 years group, 40-49 years group and 50-59 years group, and they were divided into fighter pilots, bomb-trans-helicopter pilots, and bomb-trans-helicopter crew members according to the post. The differences in various examination results of flying personnel were compared among different age groups and post groups. The influence of examination results on the aeromedical identification results was analyzed in accordance with the 3-level conclusions as not affecting the conclusion of aeromedical identification, leading to the decline of health grade and leading to temporary grounding. The overall significance level α=0.05, and the pairwise comparison with P< α/statistical times was statistically significant. Results:A total of 2 274 flying personnel was enrolled. The detection rates of various examination results from high to low was no obvious abnormality (45.82%), old lesions (37.55%), pulmonary nodules (14.86%), pulmonary bullae (6.73%), pulmonary inflammatory lesions (2.59%) and extrapulmonary diseases (1.85%). There was significant difference among examination results of different age groups ( χ2=183.43, P<0.001). The detection rate of no obvious abnormality was the highest in 20-29 years group and 30-39 years group; the detection rate of old lesions was the highest in 40-49 years group and 50-59 years group. The detection rate of no obvious abnormality decreased with age, and the detection rate of old lesions increased with age (both P< α/6=0.008). The detection rate of pulmonary nodules in 40-49 years group was higher than that in 30-39 years group; the detection rate of pulmonary bullae in 50-59 years group was higher than that in the other age groups; the detection rates of pulmonary inflammatory lesions in 40-49 years group and 50-59 years groups were higher than those in the other age groups; the detection rate of extrapulmonary diseases in 50-59 years group was higher than that in 20-29 years group, and the differences were statistically significant (all P<0.008). There was significant difference in the results of flying personnel among different post groups ( χ2=33.78, P=0.001). The detection rate of no obvious abnormality in bomb-trans-helicopter crew members group was lower than that in bomb-trans-helicopter pilots group and fighter-trainer pilots group, but the detection rates of old lesions and pulmonary nodules were higher than those in the other groups, the differences were statistically significant (all P< α/3=0.017). The detection rate of pulmonary bullae in fighter-trainer pilots group was lower than that in bomb-trans-helicopter crew members group, and the difference was statistically significant ( P<0.017). Although majority of the detected results had no effect on the results of aeromedical identification, there was a significant difference in the proportion of health grade decline and temporary grounding caused by different detected diseases (Fisher exact test value was 82.81, P<0.001). Conclusions:Low-dose lung CT screening plays an important role in the physical examination and aeromedical identification for military flying personnel. It can be routinely used during the annual physical examination for flying personnel, and the aeromedical identification standards and strategies for lung related diseases should be updated synchronously.
