Inhalation injury is caused by inhalation of heat, toxic or irritating gases which lead to respiratory and pulmonary parenchyma damage. At present, the clinical understanding about it is still limited and lack of effective diagnosis and treatment standard. Based on the experience of diagnosis and treatment of domestic inhalation injury, combined with reports of international researches, criteria (expert consensus) for inhalation injury were systematically discussed from pathological and pathophysiological changes, clinical diagnosis and evaluation, and clinical treatment, which provides reference for clinical diagnosis and treatment of patients inflicted with inhalation injury.

Hepatic fibrogenesis (HF) is the common consequence of various chronic liver diseases (CLD) induced by a variety of pathogenic factors. The mechanism of HF involves the interactions within different types of liver cells, cytokines, chemokines, cell mediators and multiple signaling pathways in a way of networks. As a result, excessive production and deposition of extracellular matrix (ECM) mainly composed of type I and type III fibril forming collagen destroys the original morphology, structure and function of the liver. The activation of hepatic stellate cells (HSCs), the major scar forming cells in liver, plays a crucial role in hepatic fibrogenesis. MicroRNAs are a group of short, single stranded, non-coding RNAs that can inhibit mRNA expression at the transcriptional and post transcriptional levels. They can be loaded and transferred as cargos by exosomes, to regulate the function of nearby and distant receptive cells. The expressions of many microRNAs such as miR-21, miR-29, miR-708, miR-101, miR-455, miR-146, miR-193 change significantly in activated HSCs, which regulate the activation, fibrogenic function, proliferation, apoptosis and autophagy of HSCs via affecting target genes expression and signaling pathway molecules. They are important substances and regulatory mechanism that mediate the initiation and progression of HF.

Objective: This study estimated nationally representative medical expenditures of gynecologic cancers, described treatment patterns and assessed key risk factors associated with the economic burden in the United States. Methods: A retrospective repeated measures design was used to estimate the effect of gynecologic cancers on medical expenditures and utilization among women. Data were extracted from the Medical Expenditure Panel Survey (weighted sample of 609,787 US adults) from 2007 to 2014. Using the behavioral model of health services utilization, characteristics of cancer patients were examined and compared among uterine, cervical, and ovarian cancer patients. Multivariable linear regression models were conducted on medical expenditure with a prior logarithmic transformation. Results: The estimated annual medical expenditure attributed to gynecologic cancers was $3.8 billion, with an average cost of $6,293 per patient. The highest annual cost per person was ovarian cancer ($13,566), followed by uterine cancer ($6,852), and cervical cancer ($2,312). The major components of medical costs were hospital inpatient stays (53%, $2.03 billion), followed by office-based visits (15%, $559 million), and outpatient visits (13%, $487 million). Two key prescription expenditures were antineoplastic hormones (10.3%) and analgesics (9.2%). High expenditures were significantly associated with being a married woman (p<0.001), having private health insurance (p<0.001), being from a low- and middleincome family (p<0.001), or living in the Midwest or the South (p<0.001). Conclusion The key risk factors and components were well described for the economic burden of gynecologic cancers. With a growing population of cancer patients, efforts to reduce the burden of gynecologic cancers are warranted.

A putative serine protease of T. spiralis (TsSP) was expressed in Escherichia coli and its potential as a diagnostic antigen was primarily assessed in this study. Anti-Trichinella IgG in serum samples from T. spiralis different animal hosts (mice, rats, pigs and rabbits) were detected on Western blot analysis with rTsSP. Anti-Trichinella antibodies were detected in 100% (30/30) of experimentally infected mice by rTsSP-ELISA. Cross-reactions of rTsSPELISA were not found with sera from mice infected with other parasites (S. erinaceieuropaei, S. japonicum, C. sinensis, A. cantonensis and T. gondii) and sera from normal mice. There was no statistical difference in antibody detection rate among mice infected with the encapsulated Trichinella species (T. spiralis, T. nativa, T. britovi, and T. nelsoni) (P>0.05). The results of rTsSP-ELISA showed that serum specific antibody IgG in mice infected with 100 or 500 T. spiralis muscle larvae (ML) were detectable early at 7-8 dpi, but not detected by ML ES antigen-ELISA prior to 10-12 dpi. Specific anti-Trichinella IgG was detected in 100% (18/18) of infected pigs by rTsSP-ELISA and ES-ELISA, but no specific antibodies was not detected in 20 conventionally raised normal pigs by two antigens. The results showed the rTsSP had the potential for early serodiagnosis of animal Trichinella infection, however it requires to be assayed with early infection sera of swine infected with Trichinella and other parasites.

Objective: To evaluate the association of family history with risk of major coronary events (MCE) and ischemic heart disease (IHD). Methods: After excluding participants with heart disease, stroke or cancer at baseline survey, a total of 485 784 participants from the China Kadoorie Biobank, who had no missing data on critical variables, were included in the analysis. Cox regression analysis was used to estimate the hazard ratios (HR) and 95% CI. Subgroup analyses were performed according to the baseline characteristics. Results: During a median of 7.2 years of follow-up, we documented 3 934 incident cases of MCE and 24 537 cases of IHD. In multivariable-adjusted models, family history was significantly associated with risk of MCE and IHD. The adjusted HRs (95%CI) were 1.41 (1.19-1.65) and 1.25 (1.18-1.33), respectively. History of disease among siblings was more strongly associated with early-onset MCE than parental history (HR=2.97, 95%CI: 1.80-4.88). Moreover, the association of family history with MCE and IHD was stronger in persons who were overweight or obesive, and the association between family history and MEC was stronger in smokers. Conclusion: This large-scale, prospective study indicated that family history was an independent risk factor for MCE and IHD in China. The intervention targeting major known lifestyle risk factors and the management of chronic diseases should be strengthened for Chinese population, especially for the individuals with family history were at high risk.

Objective: To describe the regional and population-related differences in calcaneus bone mineral density (BMD) across ten regions of China. Methods: Based on the results: from the second Re-survey of China Kadoorie Biobank project, in which 5% of the surviving participants were interviewed during 2013-2014 and 24 677 participants aged 38-87 years were included in the study. We excluded those people with missing data for BMD and important variables. Calcaneus BMD was measured using the quantitative ultrasound bone densitometer. We analyzed four indexes, including broadband ultrasound attenuation (BUA), speed of sound (SOS), stiffness index (SI), and T score. Results The average calcaneus BMDs of the present population were: BUA (109.7±12.6) dB/MHz, SOS (1 554.7±45.6) m/s, SI (88.3±18.8), T score (-0.74±1.28). Urban residents showed higher calcaneus BMD, so as in men. The calcaneus BMD decreased by age, with a larger decline seen in women. Current smokers and postmenopausal women presented lower calcaneus BMD, while in those who frequently drank milk or yogurt or being physically more active, had higher calcaneus BMD. Conclusion: Calcaneus BMD varied greatly among people from the ten regions of CKB study and among participants having different demographic characteristics, lifestyle behaviors or health conditions.
