Objective A correlation method for evaluating operation quality of air conditioning systems is proposed , based on the outdoor and the indoor temperature history data of the terminal user from internet of things for the central air conditioning system , for lacking efficient way to evaluate . Methods A methematical model is set up based on the variance ratio of the data of the indoor and out temperture obtained from IOT within a given time interval , and theoretically induce the possibility and correctness to employ these index to evaluate the operation quality of the central air conditioning system . Results A typical central air conditioning system of a large sacal hospital is analyzed , the results shows the variance ratio of the indoor and outdoor temperature can reflect the capacity of the central air conditioning system for controlling the indoor temperature . Conclusion The method proposed for evaluating the op-eration quality of the air conditioning system based on IOT system is theotically correct and practically efficient , and can be employed to evaluate the operation quality of the air conditioning system of large scale medical buildings .

Objective:To evaluate the relationship between the mechanism underlying methylprednisolone-induced alleviation of ventilator-induced lung injury (VILI) and p38 mitogen-activated protein kinase (p38 MAPK)/nucleotide binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) pathway in lung tissues of rats.Methods:Sixty clean-grade male Sprague-Dawley rats, weighing 270-320 g, aged 4-5 months, were divided into 3 groups ( n=20 each) using a random number table method: control group (group C), mechanical ventilation group (group V), and methylprednisolone group (group M). Group C breathed air spontaneously for 4 h without mechanical ventilation.Group V was mechanically ventilated (RR 40 times/min, V T 40 ml/kg, I∶E 1∶1, PEEP 0, FiO 2 21%) for 4 h. Group M received intravenous methylprednisolone 10 mg/kg at 20 min before mechanical ventilation.At 4 h of mechanical ventilation, broncho-alveolar lavage fluid (BALF) was collected to measure the concentrations of interleukin-1beta (IL-1β), IL-18, and tumor necrosis factor-alpha (TNF-α) and wet/dry lung weight ratio (W/D ratio), and lung tissues were obtained for microscopic examination of the histopathological changes and for detection of the expression of p38MAPK, phosphorylated p38MAPK (p-p38MAPK), NLRP3, apoptosis-related speck-like protein containing a CARD (ASC), and cysteinyl aspartate-specific protease-1 (caspase-1) (using Western blot). Results:Compared with group C, the W/D ratio of lung tissues and concentrations IL-1β, IL-18 and TNF-α in BALF were significantly increased, and the expression of p-p38MAPK, NLRP3, ASC and caspase-1 was up-regulated in group V ( P<0.05), and no significant change was found in group M ( P>0.05). Compared with group V, the W/D ratio of lung tissues and concentrations of IL-1β, IL-18 and TNF-α in BALF were significantly decreased, and the expression of p-p38MAPK, NLRP3, ASC and caspase-1 was down-regulated in group M ( P<0.05). Conclusion:The mechanism by which methylprednisolone alleviates VILI may be related to inhibition of p38MAPK/NLRP3 pathway activity and reduction of inflammatory responses in lung tissues of rats.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.
