To investigate the effects of HS on mitochondrial functions under low temperature stress, we analyzed the effects of 0.05 mmol·L NaHS and 15 μmmol·L HT (hypotaurine and HS scavenger) on mitochondria antioxidant enzyme activities and mitochondrial permeability transition pore, mitochondrial membrane fluidity, mitochondrial membrane potential, Cyt c/a ratio and H-ATPase activity in sweet cherry stigma and ovary with sweet cherry variety Zaodaguo under -2 ℃ low temperature stress. The results showed that low temperature stress increased the concentrations of mitochondrial HO and MDA, enhanced the mitochondrial membrane permeability, but decreased the mitochondrial membrane fluidity, membrane potential, Cyt c/a and H-ATPase acti-vity.

Objective: To explore the association between body mass index (BMI) and all-cause mortality among the elderly in Beijing.

Methods: This analysis was based on the Beijing multidimensional longitudinal study of aging (BLSA), which included 2,090 subjects over 55 years old and was followed-up from 1992 to 2012. BMI-mortality curves were drawn to find the optimal BMI range with the lowest mortality.

Surface broadband emissivity in the thermal infrared region is an important parameteras for the studies of the surface energy balance. This paper analyzed and offered an equation to estimate the surface broadband emissivity for the spectral domains 8~14 μm against the MODIS data, and then, the distribution characteristic of surface emissivity for Taklimakan Desert was obtained with this equation. Firstly, along two highways crossing the Taklimakan Desert, twenty sample sites were selected and their spectral of broadband emissivity were observed with Fourier Transform Infrared spectrometer (FTIR).

A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software.

Excessive scars affect a patient's quality of life, both physically and psychologically, by causing pruritus, pain and contractures. Because there is a poor understanding of the complex mechanisms underlying the processes of hypertrophic scar formation, most therapeutic approaches remain clinically unsatisfactory. In this study, we found that miR-138 was downregulated and peroxisome proliferator-activated receptor (PPARβ) was inversely upregulated in hypertrophic scar tissues compared to in paired normal skin tissues.

Objective: To summarize the clinical experience for the reconstruction of upper lip defects in different degrees.

Methods: Different treatment methods were selected to reconstruct the upper lip defects according to the subunit, size or location of defects on the upper lip. The therapeutic results were analyzed and compared.

Objective: This study aimed to provide an epidemiological modeling method to evaluate the risk of metabolic syndrome (MS) development in the coming 5 years among 35-74 year-olds from Taiwan.

Methods: A cohort of 13 973 subjects aged 35-74 years who did not have metabolic syndrome but took the initial testing during 1997-2006 was formed to derive a risk score which tended to predict the incidence of MS. Multivariate logistic regression was used to derive the risk functions and using the 'check-up center' (Taipei training cohort)as the overall cohort.

Since the KCNB1 encoding Kv2.1 channel accounts for the majority of Kv currents modulating insulin secretion by pancreatic islet beta-cells, we postulated that KCNB1 is a plausible candidate gene for genetic variation contributing to the variable compensatory secretory function of beta-cells in type-2 diabetes (T2D). We conducted two studies, a case-control study and a cross-section study, to investigate the association of common single-nucleotide polymorphisms (SNPs) in KCNB1 with T2D and its linking traits.

Objective: This study aimed to provide an epidemiological modeling in evaluating the risk of developing obesity within 5 years in Taiwan population aged 30 - 59 years.

Methods: After excluding 918 individuals who were observed at baseline, a cohort of 14 167 non-obesity subjects aged 30 - 59 years in the initial year during 1998 - 2006, was formed to derive a Risk Score which could predict the incident obesity (IO). Multivariate logistic regression was used to derive the risk functions, using the check-up center (Taipei training cohort, n = 8104) of the overall cohort.

Objective: To establish a subjective indicator system for the evaluation of sub-health status and study on its reliability and validity.

Methods: Based on the basic features of general malice and losing ability of workforce, the indicator system for sub-health status evaluation was developed according to the chronic stress on human body' s main systems. The items were adjusted according to the experience from experts and the results of the pilot study.

Background: Suboptimal health status (SHS) is characterized by ambiguous health complaints, general weakness, and lack of vitality, and has become a new public health challenge in China. It is believed to be a subclinical, reversible stage of chronic disease. Studies of intervention and prognosis for SHS are expected to become increasingly important.
