ABSTRACT

Background Air pollution is a major public health concern. Air Quality Health Index (AQHI) is a very important air quality risk communication tool. However, AQHI is usually constructed by single-pollutant model, which has obvious disadvantages. Objective To construct an AQHI based on the joint effects of multiple air pollutants (J-AQHI), and to provide a scientific tool for health risk warning and risk communication of air pollution. Methods Data on non-accidental deaths in Yunnan, Guangdong, Hunan, Zhejiang, and Jilin provinces from January 1, 2013 to December 31, 2018 were obtained from the corresponding provincial disease surveillance points systems (DSPS), including date of death, age, gender, and cause of death. Daily meteorological (temperature and relative humidity) and air pollution data (SO2, NO2, CO, PM2.5, PM10, and maximum 8 h O3 concentrations) at the same period were respectively derived from China Meteorological Data Sharing Service System and National Urban Air Quality Real-time Publishing Platform. Lasso regression was first applied to select air pollutants, then a time-stratified case-crossover design was applied. Each case was matched to 3 or 4 control days which were selected on the same days of the week in the same calendar month. Then a distributed lag nonlinear model (DLNM) was used to estimate the exposure-response relationship between selected air pollutants and mortality, which was used to construct the AQHI. Finally, AQHI was classified into four levels according to the air pollutant guidance limit values from World Health Organization Global Air Quality Guidelines (AQG 2021), and the excess risks (ERs) were calculated to compare the AQHI based on single-pollutant model and the J-AQHI based on multi-pollutant model. Results PM2.5, NO2, SO2, and O3 were selected by Lasso regression to establish DLNM model. The ERs for an interquartile range (IQR) increase and 95% confidence intervals (CI) for PM2.5, NO2, SO2 and O3 were 0.71% (0.34%–1.09%), 2.46% (1.78%–3.15%), 1.25% (0.9%–1.6%), and 0.27% (−0.11%–0.65%) respectively. The distribution of J-AQHI was right-skewed, and it was divided into four levels, with ranges of 0-1 for low risk, 2-3 for moderate risk, 4-5 for high health risk, and ≥6 for severe risk, and the corresponding proportions were 11.25%, 64.61%, 19.33%, and 4.81%, respectively. The ER (95%CI) of mortality risk increased by 3.61% (2.93–4.29) for each IQR increase of the multi-pollutant based J-AQHI , while it was 3.39% (2.68–4.11) for the single-pollutant based AQHI . Conclusion The J-AQHI generated by multi-pollutant model demonstrates the actual exposure health risk of air pollution in the population and provides new ideas for further improvement of AQHI calculation methods.

ABSTRACT

ObjectiveTo explore the mechanism of Zhuangyao Tongluo Formula(壮腰通络方,ZTF) in delaying intervertebral disc degeneration. MethodsM1 macrophages were induced from THP-1 cells using LPS, IFN-γ and PMA. The induced M1 macrophages were then co-cultured with nucleus pulposus cells in a transwell system. Fetal bovine serum was used as the control serum, and the effects of different concentrations (5%, 10%, 15%, 20%) of serum from rats treated with ZTF on the activity of M1 macrophages and nucleus pulposus cells were analyzed using MTT assay. Experiment 1 was established, including the nucleus pulposus cell control group, M1 macrophage control group, nucleus pulposus cell + ZTF group, nucleus pulposus cell + TNF control group, nucleus pulposus cell + TNF + ZTF group, co-culture group, and co-culture + ZTF group. The levels of IL-1β, and IL-18 in the culture supernatant were detected using ELISA. The mRNA expression of IL-1β and IL-18 in nucleus pulposus cells was detected using qPCR. Additionally, the expression of GSDMD protein in nucleus pulposus cells was detected using cell immunofluorescence. In experiment 2, co-culture groups were constructed using TNF-α overexpression (OE) or empty vector (EV) plasmids, including co-culture group, TNF-EV + co-culture group, TNF-EV co-culture group + ZTF, co-culture + ZTF group, TNF-OE co-culture group + ZTF, and TNF-OE + co-culture group. The mRNA and protein expression of TNF-α in M1 cells in each group were detected using qPCR and WB. ResultsThe ZTF with 10% serum was selected for subsequent experiments. The results of experiment 1 showed that compared to the control group of nucleus pulposus cells, there was no statistically significant difference in the levels of IL-1β, IL-18, mRNA, and GSDMD expression in the nucleus pulposus cells + ZTF group (P>0.05). However, the TNF-α + co-culture group showed a significant increase in IL-1β, IL-18 levels, mRNA, and GSDMD expression (P<0.01). When compared to the co-culture group, the ZTF+ co-culture group showed a significant decrease in IL-1β, IL-18 levels, mRNA, and GSDMD expression (P<0.01). The results of experiment 2 showed that there was no statistically significant difference in TNF-α mRNA and protein expression between the empty vector plasmids + co-culture group and the co-culture group (P>0.05). Compared to the empty vector + co-culture group, the expression of TNF-α mRNA and protein was significantly reduced in the empty vector co-culture + ZTF group (P<0.01). Compared to the co-culture group and the empty vector + co-culture group, the expression of TNF-α mRNA and protein was significantly reduced in the co-culture + ZTF group (P<0.01). Compared to the co-culture + ZTF group, the expression of TNF-α mRNA and protein significantly increased in the overexpression vector co-culture + ZTF group (P<0.01). Compared to the overexpression vector co-culture + ZTF group, the expression of TNF-α mRNA and protein significantly increased in the overexpression vector co-culture group (P<0.01). ConclusionZTF serum can inhibit the TNF-α-induced apoptosis of nucleus pulposus cells and delay lumbar disc degeneration by reducing the expression of TNF-α in M1 macrophages.

ABSTRACT

ObjectiveTo comprehensively evaluate the clinical value of Jintiange Capsules (JCs) in the treatment of osteoporosis (OP) and clarify the intrinsic advantages and clinical treatment characteristics of JCs, providing references for relevant departments of national health and medicine decision-making and the basis and clues for clinical and basic in-depth research. MethodBased on evidence-based medical evidence, this study integrated quantitative and qualitative methods and combined with questionnaires, official website data, human experience, pharmacoeconomic evaluation, and other research methods. From the effectiveness, safety, economy, innovation, suitability, accessibility, and traditional Chinese medicine (TCM) characteristics of the '6+1' dimension, the clinical evidence and value of JCs in the treatment of OP were comprehensively evaluated, forming the 'clinical evidence and value evaluation index'. The comprehensive evaluation of clinical value was based on the multi-criteria decision analysis framework. The expert meeting method was used to empower each dimension and value index. The clinical evidence and value evaluation software of Chinese patent medicine (CSC v2.0) was used to calculate the total value score, and the clinical advantages of JCs were comprehensively evaluated. ResultBased on randomized controlled clinical studies and systematic review, data analysis of spontaneous reporting system (SRS), case reports, non-clinical safety studies, etc., serious adverse drug reactions (ADRs) were reported after the launch of this product monitored by SRS, mainly involving abnormal liver function and adverse reactions of cardiovascular system. Therefore, the safety evidence adequacy of this product should be further improved, and the safety evaluation was Grade B. Meta-analysis showed that JCs were superior to the control group in improving the total clinical effective rate, improving bone mineral density, reducing visual analogue scale (VAS) score, and shortening fracture healing time. Combined with Grading of Recommendations Assessment, Development and Evaluation (GRADE) evidence evaluation, the comprehensive evaluation of effectiveness was Grade A. Pharmacoeconomic evaluation showed that JCs combined with calcium carbonate D3 tablets were more cost-effective than calcium carbonate D3 tablets alone in patients with OP. Compared with Gushukang capsules, JCs had more cost-effectiveness advantages, but the sample size included in the study was small, and the results needed to be verified by further studies. Combined with the results of the Comparative Assessment of Structure Prediction (CASP) evaluation list, the comprehensive economic evaluation was Grade B. JCs were the only bionic medicine of tiger bone in China with all intellectual property rights, with 3 national invention patents. Its process preparation and fingerprint detection had obvious technical advantages. It had innovative advantages in the supply base equipment, medicine resource management, production technology, and other aspects. Thus, its innovative comprehensive evaluation was Grade A. JCs were in capsule dosage form, which was relatively convenient for storage and transportation. The dosage form was suitable for indications, and the usage was easy for patients to grasp and accept. The statutory information and non-statutory information met the national standards. The comprehensive evaluation of suitability was Grade A. JCs did not contain toxic ingredients, had no restrictions on origin and prescription, and had abundant resources of original medicinal materials. The affordability of JCs in the treatment of OP was good in urban areas (14.97%) but not in rural areas (39.76%). The price was higher than that of similar Chinese patent medicines, and the comprehensive evaluation of availability was Grade B. JCs had a reasonable proportion of natural animal bones, and their composition was basically the same as that of natural tiger bones. After marketing, more than 2 000 cases of real-world clinical research evidence was accumulated, and the comprehensive evaluation of TCM characteristics was Grade B. CSC v2.0 software was used for quantitative synthesis of the '6+1' dimension, and the comprehensive clinical value of JCs in the treatment of OP was Grade A. ConclusionJCs have good clinical value in the treatment of OP, and the TCM characteristics are prominent. It is suggested that JCs can be directly transformed into the related policy results of basic clinical drug management according to procedures.

ABSTRACT

Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. The pathophysiology core issue is that the body initiates a severe inflammatory reaction in response to the invasion of pathogenic microorganisms at the initial stage of disease. Subsequently, the body begins to fight inflammation in order to balance immunity status and eventually induces the immune paralysis or immunosuppressive state characterized by exhaustion of immune cell. Both in innate immunity and in acquired immunity, some co-suppressor molecules on the surface of immune cells play important roles in immunosuppression, such as, programmed death receptor-1 (PD-1), T cell immunoglobulin and mucin-containing protein-3 (TIM-3), cytotoxic T lymphocyte associated antigen-4 (CTLA-4), natural killer cell receptor 2B4 (CD244), B and T lymphocyte attenuator (BTLA) and NKG2A (CD94), et al. Blocking the interaction between these co-suppressor molecules and their ligands can significantly reverse the immunosuppressive state in septic animal models or patients. In order to provide a reference for the monitoring and treatment of sepsis immune dysfunction, this article mainly summarizes the new findings on the role of those co-suppressor molecules in sepsis immune dysfunction in recent years.
