ObjectiveTo clarify the associations between plasma fibrinogen (Fbg) and volumetric bone mineral density (vBMD) as well as osteoporosis measured by quantitative computed tomography (QCT), and to explore the role of plasma Fbg in early screening and diagnosis of osteoporosis. MethodsPatients with hypertension who were hospitalized in the Department of Endocrinology of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2018 to June 2022 and underwent QCT examinations were included for cross-sectional analysis. The study analyzed the correlation between plasma Fbg and osteoporosis in patients. The diagnostic efficacy of plasma Fbg for osteoporosis was evaluated by the area under the receiver operating characteristic (ROC) curve (AUC). ResultsTotally 441 subjects were included in the analysis, with an average age of 46.0±14.5 years and a prevalence of osteoporosis of 6.4% (28/441). As the level of plasma fibrinogen increased, the incidence of osteoporosis significantly increased (P<0.000 1)while the average bone mineral density of L1 and L2 were significantly decreased (P<0.05). Compared with the first quartile of plasma Fbg(1.99g/L -2.37g/L), the risk of osteoporosis in the fourth quartile of plasma Fbg (3.67g/L-4.46g/L) increased by 8.85 times after adjusting for related confounding factors. ConclusionThis study found a negative correlation between plasma fibrinogen levels and bone density in patients with hypertension. Plasma fibrinogen levels may serve as a potential screening indicator for osteoporosis, aiding in early diagnosis and therapeutic monitoring. This discovery offers a new perspective for the study of bone metabolic diseases and warrants further investigation.

Objective To analyze the trends in the disease burden of pertussis in China from 1990 to 2021, and to provide a basis for the development of effective prevention and control strategies. Methods Using the 2021 Global Burden of Disease Study (GBD) database, the incidence, mortality, and disability-adjusted life years (DALYs), as well as the age-standardized rates of pertussis in China from 1990 to 2021 were analyzed. Descriptive statistical methods were employed to analyze the characteristics of the pertussis disease burden, and the Joinpoint regression model was used to analyze the trends in pertussis disease burden. Results From 1990 to 2021, the incidence, mortality, and DALYs of pertussis in China decreased from 1 503 800 cases, 10 951 deaths, and 954 900 person-years to 65 400 cases, 548 deaths, and 46 500 person-years, representing a decrease of 95.65%, 95.00%, and 95.13%, respectively. The corresponding age-standardized rates also decreased by 93.58%, 92.47%, and 92.53%, respectively. The Joinpoint regression model revealed a significant downward trend in the age-standardized incidence, mortality, and DALYs rates for pertussis (AAPCs were -8.32%, -9.65%, and -9.58%, respectively, P<0.001). The disease burden was slightly higher in females than in males, with the majority of cases occurring in children under 10 years old, particularly in infants under 1 year old, where the burden was the heaviest. As age increased, the disease burden decreased. Conclusion Between 1990 and 2021, the overall disease burden of pertussis in China showed a significant downward trend, with gender and age differences. Special attention should be given on the prevention and control of pertussis in children under 10 years old, especially in infants under 1 year old.

ObjectiveTo establish the fingerprint of seven commercially available Yangyin Qingfei preparations, to quantitatively analyze the index components, to evaluate their quality uniformity with multivariate statistical analysis, and to explore the quality differences among different dosage forms. MethodA total of 33 batches of commercially available 7 kinds of Yangyin Qingfei preparations were analyzed by high performance liquid chromatography(HPLC), the fingerprints were established and the common peaks were identified. Paeoniflorin, verbascoside, harpagoside, glycyrrhizic acid and paeonol were selected as the indicators of quality attributes to quantitatively analyze 33 batches of preparations. Based on the administration methods of Yangyin Qingfei preparations, the daily intake was calculated and the radar charts were poltted, and cluster analysis and principal component analysis were used to explore the quality differences of 7 kinds of Yangyin Qingfei preparations and the quality uniformity among different batches of the same dosage form. ResultThe similarity of fingerprints of 7 dosage forms was 0.248-0.956, suggesting that there were significant differences among different dosage forms of Yangyin Qingfei preparations, and a total of 15 common peaks were calibrated, of which peak 7, peak 8, peak 11, peak 13 and peak 15 were paeoniflorin, verbascoside, harpagoside, glycyrrhizic acid and paeonol, respectively. The radar plots showed that the average total daily intake of large honeyed pills and water honeyed pills was the highest, and the uniformity of pill components was better. The quality of 33 batches of samples was divided into poor quality and high quality by cluster analysis. Principal component analysis showed that the uniformity and dosage form of different dosage forms were significantly different, the oral liquid had the best quality homogeneity with the minimum dispersion. And the content of paeonol in different dosage forms was significantly different, which was the key component of quality control of Yangyin Qingfei preparations. ConclusionYangyin Qingfei large honeyed pills and water honeyed pills show high content and good uniformity, which are relatively preferred dosage forms. Different preparation processes have a great influence on the content of paeonol, and its quality control should be emphasized during production. This study provides a scientific method for the comparison of product quality of different dosage forms of traditional Chinese medicine prescriptions, which is helpful for the development of preferred dosage forms of different prescriptions, and provides a reference for efficient use of medication in the clinical practice.

OBJECTIVE
To establish a ultra-high-performance liquid chromatography-mass spectrum/mass spectrum(UPLC-MS/MS) method for the determination of anlotinib in human plasma and assessment of clinical application.
METHODS
Zanubrutinib was used as internal standard and the extraction process was performed through protein precipitation method using acetonitrile, followed by separation on an Ultimate XB-C18(100 mm×2.1 mm, 3.0 μm) column using acetonitrile and 10 mmol·L−1 ammonium acetate-0.1% formic acid step-elution gradient. The flow rate was 0.6 mL·min−1 and injection volume was 5 μL. The mass analysis was performed by positive ion electrospray ionization in multiple-reaction monitoring mode, and the mass spectrometer was set at m/z 408.1→339.1 for anlotinib and m/z 472.2→290.1 for internal standard, respectively. The specificity, standard curve and lower limit of quantification, precision and recovery, matrix effect and stability of the method and clinical application were investigated.
RESULTS
The method was validated over the concentration range of 1.0−100.0 ng·mL−1, with R2=0.998 4. The precision RSD was<9%, the recovery and matrix effect were 104.81%−107.32% and 102.54%−105.26%, respectively, and this method had good stability and was not affected by matrix effect. The method had been used for determined 52 advanced non-small cell lung cancer patients treated with anlotinib. The trough plasma concentration (Ctrough) was measured on day 43 after initiation of anlotinib treatment. Anlotinib Ctrough were higher than lower limit of quantitation (1.0 ng·mL−1) from 52 patients. The plasma concentration of anlotinib Ctrough was (11.38±4.29)ng·mL−1 with 37.66% coefficients of variation, which were shown large inter-patient variability.
CONCLUSION
This method is high sensitivity, specificity and accurate, and suitable for determination of anlotinib in human plasma.

Objective:To analyze the relationship between killer cell immunoglobulin-like receptor ( KIR) genes and immune reconstitution failure in human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) patients after anti-retroviral therapy (ART). Methods:HIV/AIDS patients receiving ART for ≥1 year who attended the AIDS outpatient clinics of Wuming Hospital of Guangxi Medical University and People′s Hospital of Mashan from May 2007 to December 2019 were included. Patients were divided into immune reconstitution failure group and full immune reconstitution group. Polymerase chain reaction with sequence specific primers (PCR-SSP) was used to detect KIR genotypes in all subjects, and the genotype frequency (PF) of 16 KIR genotypes was calculated. Statistical analysis was conducted using chi-square test. Multivariate logistic regression was used to analyze the relationship between KIR genotypes and immune reconstitution failure.Results:There were 102 patients with HIV/AIDS, including 44 immunological non-responders and 58 immunological responders. The PF of KIR2 DL5 in immune reconstitution failure group was 59.09%(26/44), which was higher than 36.21%(21/58) in full immune reconstitution group, and the difference was statistically significant ( χ2=5.27, P=0.022). Multivariate logistics regression analysis showed that KIR2 DL5 was associated with immune reconstitution failure when adjusted for age and baseline CD4 + T cell count. Positive expression of KIR2 DL5 may be a risk factor for immune reconstitution failure (adjusted odds ratio (a OR)=2.431, 95% confidence interval 1.012 to 5.844, P=0.047). Conclusions:Positive expression of KIR2 DL5 may be related to immune reconstitution failure in HIV/AIDS patients after ART.

Chinese patent medicines(CPMs) are unique therapeutic drugs in China. Establishing and improving the evaluation criteria is an important measure to promote the high-quality development of CPMs. Based on the "evaluation criteria of high-grade CPMs with quality as the core index" established by our group in 2018, the "high-quality evaluation criteria for CPMs based on whole process control" was proposed in the present study in 2022. The scope of application and basic principles of the new criteria were clarified. A quality evaluation scoring table was established in the new criteria, including five parts: raw material selection, production process, quality control, efficacy evaluation, and brand building. The technical evaluation indexes involved have increased from 20% in the original criteria to 70% in the new criteria, and efficacy evaluation has been added in the new criteria. The subjective evaluation indicators account for a large proportion in the original criteria, which is prone to bias. The improved criteria overcome this shortcoming. It is expected that the new criteria as a basis can play a better role in the selection of high-quality products of CPMs, guide enterprises and institutions to participate actively in the evaluation and research of high-quality CPMs, and promote the high-quality development of CPMs.
