Objective To develop an automated system for the determination of gross α and gross β activity concentrations in water, and to support the rapid and automated monitoring of environmental water bodies. Methods Based on the thick source method, microwave evaporation-ashing was used to replace conventional electric hotplate heating. A grinder and a sample-spreading device were designed and operated via a robotic arm, achieving fully automated pretreatment, sample preparation, and measurement. Results Spike recovery tests demonstrated that the recovery rates were 95.7%-102.5% for gross α and 97.2%-108.1% for gross β. The relative standard deviations were 4.1%-7.8% for gross α and 5.9%-7.7% for gross β. Compared with manual laboratory methods, the average relative errors were 2.17%-6.25% for gross α and 4.17%-6.90% for gross β. The sample preparation time was reduced from an average of 72 hours to less than 5 hours, representing an efficiency improvement of over 90%. Conclusion The developed system enables rapid, accurate, and fully automated monitoring of gross α/β radioactivity, making it suitable for online monitoring of environmental water bodies. It can provide timely data on the radiological indicators of water bodies for environmental protection and water resource management authorities.

Objective:To study the epidemiological characteristics and clinical diagnosis of human brucellosis in Qujing City, Yunnan Province.Methods:Through the Infectious Disease Reporting Information Management System of the China Disease Prevention and Control Information System, the basic information and clinical diagnostic data of brucellosis cases reported in Qujing City from January 2008 to December 2023 were retrospectively collected. Descriptive epidemiological methods were used to analyze the epidemic profile, three distribution characteristics (time, population, region), and diagnosis of brucellosis.Results:A total of 1 417 brucellosis cases were reported in Qujing City from 2008 to 2023, with no death. The annual average incidence of brucellosis was 1.49/100 000, with no cases reported in 2009 and 2010, and the highest incidence in 2023 (7.82/100 000). The incidence of brucellosis showed an increasing trend year by year (χ 2trend = 1 874.58, P < 0.001). The number of cases from June to November accounted for 61.54% (872/1 417). The majority of brucellosis cases were in the age group of 36 - 65 years old, accounting for 67.82% (961/1 417). Among them, there were 954 males and 463 females, with a gender ratio of 2.06 ∶ 1.00. Farmers were the main occupation, accounting for 84.33% (1 195/1 417). The cases were mainly distributed in Luliang County (621 cases), Xuanwei City (282 cases) and Shizong County (137 cases), accounting for 73.39% (1 040/1 417). The median interval between onset and diagnosis was 13 days, and the cases with intervals ≤7 d, 8 - 30 d, and ≥31 d accounted for 32.11% (455/1 417), 40.16% (569/1 417), and 27.73% (393/1 417), respectively. Totally 63.94% (906/1 417) of the cases were confirmed in medical institutions in Qujing City. Conclusions:The incidence of brucellosis in Qujing City is increasing year by year, with men, middle-aged and elderly people and farmers as the main population, summer and autumn as the peak period, and Luliang County, Xuanwei City and Shizong County as the high incidence areas. Most cases have an interval of less than 30 days between onset and diagnosis, and can be diagnosed within the jurisdiction.

Objective:To explore the correlative factors for insomnia severity in chronic insomnia patients using MemTrax memory test.Methods:Two hundred and twenty-two chronic insomnia patients (insomnia≥3 days per week with a duration≥3 months) recruited from Center for Preventive Treatment of Diseases, Guangdong Provincial Hospital of Chinese Medicine or through in-hospital advertisements from April 2024 to September 2024 were chosen. Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep quality over the last month; according to PSQI score, these patients were divided into mild insomnia group (scores of 7-10), moderate insomnia group (scores of 11-15) and severe insomnia group (scores of 16-21). MemTrax memory test was used to record the picture recognition accuracy and picture recognition reaction time, and MemTrax comprehensive index (MTx-Cp) was calculated; Patients' Health Questionnaire (PHQ-9), and Generalized Anxiety Disorder-7 scale(GAD-7) were used to evaluate the depression and anxiety status of these patients in recent 2 weeks. The clinical data, MemTrax test results, PHQ-9 and GAD-7 scores of patients with different degrees of chronic insomnia were compared. Spearman rank correlation analysis was used to investigate the correlation between insomnia severity and clinical data such as cognitive memory function in chronic insomnia patients.Results:Among the 220 chronic insomnia patients, 54 had mild insomnia, 111 had moderate insomnia, and 55 had severe insomnia. Severe insomnia patients had significantly higher percentages of those>50 years old and those using hypnotics compared with mild insomnia patients and moderate insomnia patients ( P<0.05). Compared with the mild insomnia patients and moderate insomnia patients, the severe insomnia patients exhibited significantly lower picture recognition accuracy (90%[86%, 94%], 88%[82%, 94%], 84%[78%, 92%]), significantly lower MTx-Cp (88.55±18.67, 84.41±20.93, 76.69±17.43), and significantly higher PHQ-9 score (9[6, 11], 9[6, 15], 12[8, 16], P<0.05). Moreover, severe insomnia patients had significantly longer picture recognition reaction time and higher GAD-7 score than mild insomnia patients (1.11[1.03, 1.24] s vs. 1.04[0.90, 1.15] s; 7[5, 13] vs. 6[3, 9], P<0.05). Spearman rank correlation analysis showed that insomnia severity in chronic insomnia patients was positively correlated with age, PHQ-9 score, GAD-7 score, and picture recognition reaction time, and negatively correlated with picture recognition accuracy and MTx-Cp ( P<0.05). Conclusion:Insomnia severity in patients with chronic insomnia is correlated with age, cognitive memory function, depression and anxiety.

Danggui Liuhuangtang is the 47th of the 100 famous classical formulas published by the National Administration of Traditional Chinese Medicine, and is known as the holy medicine for night sweat. By bibliometrics, the authors collected the ancient books on Danggui Liuhuangtang and screened out 269 valid data, involving 156 ancient books of traditional Chinese medicine. The analysis on the historical origin, disease syndromes, pathogenesis, composition, dosage, preparation, usage, and processing of Danggui Liuhuangtang found that this famous classical formula originated from Secret Book of the Orchid Chamber (《兰室秘藏》) written by LI Dongyuan, and is composed of Angelicae Sinensis Radix, Rehmanniae Radix, Rehmanniae Radix Praeparata, Phellodendri Chinensis Cortex, Scutellariae Radix, Coptidis Rhizoma and Astragali Radix. It has the functions of nourishing Yin, reducing fire, consolidating exterior and stopping sweating, and mainly treats night sweat due to Yin deficiency and fire exuberance. In the later generations, disease syndromes are mostly treated based on LI Dongyuan's theory, and have expanded to more than 30 kinds (339 in total), among which night sweat (208) was the most, accounting for 61.36% of the total disease syndromes, followed by spontaneous sweating (38), accounting for 11.21%. Additionally, it was found that Danggui Liuhuangtang was widely used in modern clinical practice for various disease syndromes. Among them, endocrine disease (77, 28.21%) was predominant, followed by gynecological disease (48, 17.58%), and pediatric disease (24, 8.79%). Although Danggui Liuhuangtang treats many disease syndromes, their pathogenesis was always yin deficiency and fire exuberance. Through the systematic excavation of the ancient books on Danggui Liuhuangtang and the analysis of its modern clinical application, this paper probed into the historical evolution and confirmed the key information of the formula, providing detailed literature basis for the research and development application of famous classical formulas.

ObjectiveTo evaluate the efficacy and safety of topical Bisaitong (鼻塞通) in treating moderate-to-severe allergic rhinitis (AR). MethodsA randomized, positive-controlled, non-inferiority clinical trial design was adopted. Totally, 108 cases of moderate-to-severe AR were randomly divided into Bisaitong group and mometasone furoate group,with 54 cases in each group. The Bisaitong group was treated with Bisaitong smeared at the nasal cavity twice a day, and the mometasone furoate group received inhalation of mometasone furoate nasal spray 100 μg in each nostril, once a day. Both groups were treated for 4 weeks and followed up after additional 4 weeks. Both groups were compared on the rhinoconjunctivitis quality of life questionnaire (RQLQ), rhinoconjunctivitis total symptom score (RTSS), visual analogue score (VAS) of sneezing, runny nose, nasal itching, nasal congestion degree, days of AR episodes at enrollment, after 2- and 4-week, and at follow-up. The peripheral blood eosinophil (EOS) count and percentage (EOS%), serum eosinophil cationic protein (ECP), serum dust mite, dermatophagoides farinae, and cockroach allergen-specific IgE (sIgE) levels were compared between groups at enrollment and after 4-week treatment. Drug overuse rate was calculated, and the safety was evaluated. The analysis of all efficacy outcomes was based on both full analysis set (FAS) and per-protocol set (PPS). ResultsThe lower limit of the 95% confidence interval for the differences in RQLQ scores were greater than -0.6 measured after 2- and 4-week treatment and at follow-up compared to that measured at the enrollment in both groups, indicating of the Bisaitong group being non-inferior to the mometasone furoate group. There was no statistically significant difference between groups on RTSS score, VAS scores of sneezing, runny nose, nasal itching, nasal congestion degree and days of episodes at all timepoints (P>0.05), but each outcome changed significantly over time in both groups (P<0.01). The differences between groups in EOS count, EOS%, ECP levels, serum dust mite, dermatophagoides farinae, cockroach sIgE levels, and drug overuse rate were not statistically significant at enrollment and after 4-week treatment (P>0.05). Adverse events occurred in eight cases (15.10%) in the Bisaitong group and five cases (9.30%) in the mometasone furoate group, showing no significant difference between groups (P>0.05). ConclusionTopical Bisaitong is non-inferior to mometasone furoate nasal spray in the treatment of moderate to severe AR in terms of clinical symptom relief,reduction in the episodes, improvement of quality of life, and sound safety.

ObjectiveTo explore the effect of Anmeidan on the sleep quality and serum levels of brain-derived neurotrophic factor (BDNF), glial fibrillary acidic protein (GFAP), and irisin in the patients with chronic insomnia. MethodA multicenter, randomized, double-blind, placebo-controlled clinical study was carried out, including 480 patients with chronic insomnia (deficiency syndrome) in Wuhan (Hubei), Guangzhou (Guangdong), and Lanzhou (Gansu). They were randomized into an observation group and a control group at a ratio of 1∶1. The observation group was orally administered with Anmeidan granules at a dose of 11 g, 3 times per day, and the control group with Anmeidan simulant at a dose of 11 g, 3 times per day, Both groups of patients received sleep education after enrollment. After 4 weeks of medication, the Athens insomnia scale (AIS) scores, Spiegel scale scores, and serum levels of BDNF, GFAP, and irisin were compared between the two groups as well as between before and after treatment. ResultA total of 480 adult patients with chronic insomnia were enrolled in this study, with 64 patients falled off. Finally, the 415 patients were included in the analysis, including 213 patients in the observation group and 202 patients in the control group. There was no difference in age or sex between the two groups of patients. Compared with before treatment, the treatment in both groups decreased the AIS and Spiegel scores (P<0.01). After treatment, the observation group had lower AIS and Spiegel scores than the control group (P<0.01). The treatment in the observation group slightly lowered the level of BDNF, elevated the level of irisin (P<0.05), and lowered the level of GFAP (P<0.05) in the serum. After treatment, the observation group showed higher level of irisin (P<0.05) and lower levels of BDNF and GFAP in the serum than the control group. ConclusionAnmeidan may improve the sleep quality of patients with chronic insomnia by elevating the irisin level and lowering the GFAP level in the serum.
