Guided by the TCM theory of“the lung and large intestine are interrelated”,this paper analyzes severe pneumonia with Qi-Yin deficiency syndrome.Combined with the connotation of Zang-Fu viscera correlation theory and modern research on lung-intestine correlation,it sorts out the core pathogenesis of simultaneous lung and intestinal disease complicated with deficiency of both Qi and unobstructed Fu Qi in this disease,and elaborates the formula logic and clinical application value of Xinhuanglong Decoction for replenishing Qi and nourishing Yin,unblocking Fu organs and clearing heat.Most patients with severe pneumonia are accompanied by varying degrees of gastrointestinal injury and severe systemic inflammatory response.The elderly and patients with chronic illnesses and physical weakness are more prone to develop a complicated pathogenesis of intermingled deficiency and excess.With simultaneous purgation and tonification,Xinhuanglong Decoction can effectively improve gastrointestinal motility and reduce the level of inflammatory indicators,shorten the duration of mechanical ventilation and ICU hospitalization,and is more suitable for elderly and chronically ill patients with severe pneumonia of Qi-Yin deficiency syndrome.This prescription embodies the TCM diagnosis and treatment idea of simultaneous treatment of lung and intestine,possesses high clinical application potential,and can provide references for integrated traditional Chinese and Western medicine treatment of severe pneumonia,worthy of further verification and promotion through large-sample clinical studies. 展开更多

This paper investigates the online inventory problem with interrelated prices in which a decision of when and how much to replenish must be made in an online fashion even without concrete knowledge of future prices. Four new online models with different price corre- lations are proposed in this paper, which are the linear-decrease model, the log-decrease model, the logarithmic model and the exponential model. For the first two models, the online algo- rithms are developed, and as the performance measure of online algorithm, the upper and lower bounds of competitive ratios of the algorithms are derived respectively. For the exponential and logarithmic models, the online algorithms are proposed by the solution of linear programming and the corresponding competitive ratios are analyzed, respectively. Additionally, the algorithm designed for the exponential model is optimal, and the algorithm for the logarithmic model is optimal only under some certain conditions. Moreover, some numerical examples illustrate that the algorithms based on the dprice-conservative strategy are more suitable when the purchase price fluctuates relatively flat. 展开更多

The decreasing of hazard ratio for cancer incidence (HRCVD) in the range of twenty native tissues (lung, liver, brain, hematologic, neuroendocrine renal, pancreas, lymphoid, bladder, colon, lip-oral-head-neck, leukocy... The decreasing of hazard ratio for cancer incidence (HRCVD) in the range of twenty native tissues (lung, liver, brain, hematologic, neuroendocrine renal, pancreas, lymphoid, bladder, colon, lip-oral-head-neck, leukocytic, rectum and anus, thyroid, soft tissue, prostate, skin, ovarian, breast, uterine) as much, as decreasing of the level of cardiovascular pathology (CVD) in the host before malignization, have been described by C.F. Bell et al. in 2023. Earlier, in 2022, the decreasing of 5-year mortality from cancer in similar range of tissues discussed by us as the inverse dependence from the content of stem CD34 markers in tissues before malignization, with example of population in England. In present article we investigate the interrelation between both data more thoroughly, using accessible and more representative populations level of the data. The analysis shows that high level of HRCVD is able to predicts only high cancer death for tissue sites in the beginning of the range, being applied to the referent data of cancer cases and deaths in estimated population of USA 2024. Along with this, an increasing the content of CD34 stem marker in the native tissues of the same range was favorite for increasing of cancer’s cases at the end of the range, diminishing, in parallel, the signs of vasculo-endothelial pathology, i.e. HR CVD. Thus, the cases (incidence) of cancer depend directly rather from content of CD34, which preexisted in native sites, than that from HRCVD. Further analysis shows that CD34 content averaged over twenty cites dominates over that CD2 marker of total T-cells more than 7 times, in oppose to their ratio in the blood. The enhancement of stem CD34 marker in the range of tissues is accompanied by unidirectional rising of its maturing derivatives, vasculo-endothelial CD31 and total T-cells CD2 markers, which contents relate positively to increasing of cancer death in US population 2024. The increase of CD34 decreases cancer mortality (death: cases) in sites, but indirectly, rather due to enhancement of the denominator. The high HRCVD (more than 1.0) in range of 20 tissues, concerns of those of them, which have had highest mitotic activity (by Ki67), but lowest “stemness” (by CD34), “vascularity” (by CD31), cancer’s incidence (cases) and the worse results of therapy. Oppositely, the normal tissue with lowest HRCVD (below 1.0) and Ki67, but highest CD34, CD31, and cancer incidence (cases) are more sensitive to treatment. Thus, the residential hematopoietic “stemness” in native tissues acts as natural protectors for cardio-vascular system and promoter for cancer incidence in them. The steady and irreversible exhaustion of current regenerative resource (CRR) of BM, which assumed by us as a product of CD34 number and average telomeres length, manifests itself in acceleration of non-malignant CVD and deceleration of malignancy in population +70 (in term the death per 105), according to data extracted from WHO Mortality Database. The similar deficit of CD34 arises artificially during cytotoxic treatment of cancer, when rapid waste of local CRR forces malignant cells to search more “stemness” cites. The competition between malignant and native tissues of the host for scanty CRR seems to be the most important factor for evaluation and prediction of prevalence, curability, and long-term results in oncology. 展开更多

In order to comprehend the dynamic disaster mechanism induced by overburden rock caving during the advancement of a coal mining face, a physical simulation model is constructed basing on the geological condition of the 21221 mining face at Qianqiu coal mine in Henan Province, China. This study established, a comprehensive monitoring system to investigate the interrelations and evolutionary characteristics among multiple mechanical parameters, including mining-induced stress, displacement, temperature, and acoustic emission events during overburden rock caving. It is suggested that, despite the uniformity of the overburden rock caving interval, the main characteristic of overburden rock lies in its uneven caving strength. The mining-induced stress exhibits a reasonable interrelation with the displacement, temperature, and acoustic emission events of the rock strata. With the advancement of the coal seam, the mining-induced stress undergoes four successive stages: gentle stability, gradual accumulation, high-level mutation, and a return to stability. The variations in other mechanical parameters does not synchronize with the signifcant changes in mining-induced stress. Before the collapse of overburden rock occurs, rock strata temperature increment decreases and the acoustic emission ringing counts surges with the increase of rock strata displacement and mining-induced stress. Therefore, the collaborative characteristics of mining-induced stress, displacement, temperature, and acoustic emission ringing counts can be identifed as the precursor information or overburden rock caving. These results are in good consistent with on-site situation in the coal mine. 展开更多

BACKGROUND:There are significant variations in the geographical distribution of hepatitis B virus(HBV)genotypes throughout the world,and some genotypes are associated with different clinical outcomes.Eight genotypes of human HBV(designated A-H)have been reported.The present study was designed to examine the distribution of HBV genotypes among patients at various stages of chronic type B liver disease in Yunnan Province,China,and to explore its significance and the relationship of HBV genotype with gender and age,clinical spectrum of chronic HBV infection,and viral replicative activity.METHODS:Serum samples from 126 patients with chronic HBV infection from Yunnan Province,including 26 chronic asymptomatic HBV carriers(ASC),61 patients with chronic hepatitis B(CHB)(21 mild,30 moderate and 10 severe),20 patients with chronic fulminant hepatic failure(CFHF),12 patients with HBV-related liver cirrhosis(LC)and 7 patients with HBV-related hepatocellular carcinoma(HCC)were analyzed using reverse dot blot(RDB)methodology,which is based on the reverse hybridization principle for HBV genotyping.The relations of HBV genotype with gender and age,clinical patterns,and serological data of the patients were analyzed.RESULTS:In this series,genotypes A,B,C,and D were found.38.1%patients(48/126)belonged to B,54.8%(69/126)to C,0.8%(1/126)to D,1.6%(2/126)to a mixture of B and C,and 1.6%(2/126)to a mixture of A and C.3.2%patients(4/126)had unknown genotypes.No other genotypes(E,F,G,and H)were found.Genotypes B and C were predominant.There was a statistically significant difference in the distributions of genotypes C and B(chi(2)=7.04,P=0.008),and C was the dominant genotype in all patient categories.The rate of genotype B in the mild CHB group was significantly higher than that in the moderate and severe groups(chi(2)=12.16,P=0.0001;chi(2)=11.98,P=0.001,respectively),the ASC group(chi(2)=5.46,P=0.02),the CFHF group(chi(2)=5.53,P=0.019),and the LC/HCC group(chi(2)=12.13,P=0.001).The rate of genotype C in the LC/HCC group and the severe CHB group were significantly higher than that in the mild group(chi(2)=9.95,P=0.002;chi(2)=8.78,P=0.003,respectively).HBV DNA positivity and HBeAg positivity were higher in genotype C than in genotype B(chi(2)=9.81,P=0.002;chi(2)=3.85,P=0.05,respectively).The prevalence of genotype C showed an increasing trend in lowest-,middle-and highest-level groups of HBV replication(25.0%,70.0%,and 55.6%,respectively);in contrast,the prevalence of genotype B showed an opposite trend in the same order(62.5%,30.0%,and 37.0%,respectively).The rate of genotype C in the highest-level group of HBV replication was higher than genotype B(chi(2)=7.45,P=0.006).The rate of genotype C in the over-30 age group was higher than that in the below-30 age group(chi(2)=3.7,P=0.05).There was no difference between the sexes(P>0.05).More severe liver damage was found in genotype C than in genotype B(P<0.05).CONCLUSIONS:The predominant HBV genotypes in chronic HBV-infected patients are B and C,and C is the most prevalent genotype in Yunnan Province,China.HBV genotype C is associated with the development of more severe liver disease and a higher level of HBV viral replication,and genotype B has a relatively good progress. 展开更多

Frictional stick–slip instability along pre‐existing faults has been accepted as the main mechanism of earthquakes for about 60 years,since it is believed that fracture of intact rocks cannot reflect such features inherent in earthquakes as low shear stresses activating instability,low stress drop,repetitive dynamic instability,and connection with pre‐existing faults.This paper demonstrates that all these features can be induced by a recently discovered shear rupture mechanism(fan‐hinged),which creates dynamic ruptures in intact rocks under stress conditions corresponding to seismogenic depths.The key element of this mechanism is the fan‐shaped structure of the head of extreme ruptures,which is formed as a result of an intense tensile cracking process,with the creation of inter‐crack slabs that act as hinges between the shearing rupture faces.The preference of the fan mechanism over the stick–slip mechanism is clear due to the extraordinary properties of the fan structure,which include the ability to generate new faults in intact dry rocks even at shear stresses that are an order of magnitude lower than the frictional strength;to provide shear resistance close to zero and abnormally large energy release;to cause a low stress drop;to use a new physics of energy supply to the rupture tip,providing supersonic rupture velocity;and to provide a previously unknown interrelation between earthquakes and volcanoes.All these properties make the fan mechanism the most dangerous rupture mechanism at the seismogenic depths of the earth's crust,generating the vast majority of earthquakes.The detailed analysis of the fan mechanism is presented in the companion paper“New physics of supersonic ruptures”published in DUSE.Further study of this subject is a major challenge for deep underground science,earthquake and fracture mechanics,volcanoes,physics,and tribology. 展开更多

In order to further reveal the interrelation among division of seismic statistical regions, delimitation of potential seismic sources and estimation of seismicity parameters, we select 21 representative sites located in different places within the range of 100°-120°E, 29°-42°N to study the influences of seismicity parameter uncertainties of statistical regions on seismic risk estimations of these sites in the inhomogeneous and homogeneous distribution models. Combining the results from this study and previous ones, we can see that different schemes for dividing seismic statistical regions can change the seismic data in a statistical region. The uncertain data and additional uncertainty in selecting time intervals for seismic statistics will result in uncertainty of seismicity parameters estimation in a statistical region. For the homogeneous model, the larger the variation of this uncertainty is, the greater the uncertain influence on the seismic risk estimation of a site will be, which means that the division of seismic statistical regions makes a major contribution. In a seismic statistical region, the delimitation of potential sources and variant weight assignment of spatial distribution functions can raise the estimated values of ground motion parameters in the place where great earthquake might occur and its vicinity. In these places, the influence of uncertainty in potential source delimitation is very obvious, especially on the absolute magnitude of ground motion parameters （e.g., intensity）, which means that the link of potential source delimitation makes a major effect. Generally speaking, the link of potential source delimitation affects mainly the sites located in the potential sources with the highest and second-high upper-limit earthquake magnitudes or in the vicinity of those with the highest upper-limit magnitude. While for the sites located in the potential sources with low upper-imit magnitudes, the uncertainty influence of statistical region division is larger than that of potential source delimitation. 展开更多
