The cardiovascular and cerebrovascular diseases have become a main category of disease which affects human health today.It is helpful to search for its causes and main risk factors for scientific prevention and control of these diseases.Now,we have already paid close attention to effect of the airborne contaminant and meteorological factors on the cardiovascular and cerebrovascular diseases.Some reports about solo affect of two types factors have given a clear results;however,a little of unification evidences have been provided.This article reviews the solo and unification effects of pollutants and meteorological factors in the cardiovascular and cerebrovascular diseases.

Objective To innovate an early, rapid and efficient approach to the pmgnestic evaluation of sep-sis in order to lower the mortality. Method Forty-five septic rats, induced by cecal ligation and puncture, were divided into surviving group (n=23) and non-survival group (n=22) on six days after onset of sepsis. Serum samples were taken from septic and sham-operated rats (n=25) at 12 hours after surgery. HPLC/MS assays were performed to acquire the serum metabolic profiles, and radial basis function neural network (RBFNN) was em-ployed to build predictive model for prognostic evaluation of sepsis. Results The principal component analysis al-lows differentiating the rots of survive,non-survive and sham-operated from one another in respect of the pathologic characteristics. Six metabolites, linolenic acid, linoleic acid, oleic acid, stearic acid, docosahexaenoic acid and do-cosapentaenoic acid, related to the outcomes of septic rats were then structurally identified. A RBFNN model for outcome predication was built based upon the metabolic profile data from rat sera with the sensitivity of (96.1 ±3.6)% (n=10) and specificity of (91.0±4.3)% (n=10). Condusions HPLC/MS-based metabonomic approach combined with pattern recognition permits accurate outcome prediction of septic rats in the early stage. The proposed approach has advantages of rapid, low-cost and efficiency, and is isph-ing to be applied in clinical prognostic evaluation of septic patients.

The Wendan Decoction,a classic prescription first recorded in Yao Shengyuan's"Ji Yan Fang"during the Southern and Northern Dynasties,has been a mainstay in Traditional Chinese Medicine(TCM)clinical applications.Recently included in the first batch of the"Catalogue of Ancient Classical Famous Prescriptions"and highlighted in the"Key Information List of Ancient Classical Famous Prescriptions(25 Prescriptions)",this paper summarizes the research progress on Wendan Decoction.The decoction is recognized for its lipid-lowering,blood pressure-reducing,anti-inflammatory,and anti-schizophrenic properties,and is extensively used in modern clinical practice,especially for neurological,cardiovascular,digestive,and endocrine system disorders.In TCM,Wendan Decoction is often tailored and applied in cases diagnosed with phlegm and stasis.Referencing the"Q-marker"quality standard proposed by Academician Liu Changxiao in 2016,this study predicts the quality markers of Wendan Decoction based on the"five principles",identifying β-sitosterol,succinic acid,quercetin,tricin,luteolin,naringin,nobiletin,hesperidin,naringenin,6-gingerol,glycyrrhizin,and glycyrrhetinic acid as key constituents.These findings are intended to facilitate the refinement of Wendan Decoction's prescription and enhance its clinical effectiveness.

Objective:To explore the effects of Sangqiao Qingfei Prescription combined with Western medicine conventional therapy with mechanical ventilation on lung function and airway inflammation in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) respiratory failure; To evaluate clinical efficacy.Methods:A randomized controlled trial study was conducted. Totally 90 AECOPD patients with respiratory failure in our hospital from January 2020 to December 2022 were selected as the observation subjects. They were divided into two groups using a random number table method, with 45 cases in each group. The control group received mechanical ventilation treatment, while the observation group received Sangqiao Qingfei Prescription on the basis of the control group. Both groups were treated for 2 weeks. TCM syndrome scoring was performed before and after treatment, and the time of successful withdrawal from the machine was recorded; a blood gas analyzer was used to detect PaO 2, PaCO 2, blood oxygen saturation (SaO 2) and pH values; the plateau pressure (Pplat), peak airway pressure (Ppeak), airway resistance (Raw) and dynamic lung compliance (Cdyn) were recorded during the ventilator; a pulmonary function meter was used to measure respiratory rate (RR), maximum expiratory flow (PEF), FVC, FEV1, and the percentage of FEV1 to the estimated value (FEV1% estimated value); serum CRP, TNF-α, and Procalcitonin (PCT) were detected using ELISA method. Clinical efficacy was evaluated. Results:During the treatment period, there were no cases of detachment in both groups. The mechanical ventilation time in the observation group was (7.16 ± 0.69) d, while in the control group it was (9.88 ± 1.04) d, with statistical significance ( t=14.62, P<0.001); after treatment, the main symptom, secondary symptom scores, and total scores of the observation group were lower than those in the control group ( t values of 13.43, 18.53, 31.21, P<0.001); the PaO 2 [(79.16 ± 7.42) mmHg vs. (67.49 ± 6.88) mmHg, t=8.24], SaO 2 [(95.15 ± 9.93)% vs. (84.59 ± 9.48)%, t=5.16], and pH value (7.35 ± 0.23 vs. 7.26 ± 0.16, t=2.16) in the observation group were higher than those in the control group ( P<0.01 or P<0.05), while PaCO 2 [(49.89 ± 3.65) mmHg vs. (62.39 ± 4.27) mmHg, t=14.93] was lower than that of the control group ( P<0.01); after treatment in the observation group, Pplat [(15.31 ± 2.51) cmH 2O vs. (17.53 ± 2.02) cmH 2O, t=4.62], Ppeak [(22.43 ± 3.16) cmH 2O vs. (25.78 ± 3.17) cmH 2O, t=5.02], Raw [(18.96 ± 3.86) cmH 2O/(S?L) vs. (24.29 ± 4.29) cmH 2O/(S?L), t=6.20] were lower than those in the control group ( P<0.01), Cdyn [(34.53 ± 3.35) cmH 2O/(S?L) vs. (30.27 ± 3.87) cmH 2O/(S?L), t=5.58] was higher than the control group ( P<0.01); the RR [(19.25 ± 2.43) times/min vs. (23.49 ± 3.07) times/min, t=7.26] in the observation group was lower than that of the control group ( P<0.01), PEF [(4.99 ± 0.40) L/s vs. (4.03 ± 0.34) L/s, t=12.27], FVC [(3.04 ± 0.20) L vs. (2.14 ± 0.22) L, t=20.31], FEV1 [(2.83 ± 0.20) L vs. (2.16 ± 0.13) L, t=18.84], FEV1% estimated value [(42.23 ± 4.66)% vs. (36.43 ± 5.09)%, t=5.64] were higher than those in the control group ( P<0.01); serum CRP, IL-6, TNF-α and PCT in the observation group were lower than those in the control group ( t values were 18.13, 13.36, 15.97, 30.67, P<0.01). The total effective rate of the observation group was 93.33% (42/45), while that of the control group was 77.78% (35/45), with statistical significance ( χ2=4.41, P=0.036). Conclusion:The combination of Sangqiao Qingfei Prescription and conventional Western medicine treatment with mechanical ventilation can effectively improve lung ventilation function, reduce inflammatory cytokine levels, alleviate inflammatory reactions, and improve clinical efficacy in AECOPD patients with respiratory failure.
