Background: The impact of hospital volume on the long-term survival of esophageal squamous cell carcinoma (ESCC) has not been well assessed in China, especially for stage I-III stage ESCC. We performed a large sample size study to assess the relationships between hospital volume and the effectiveness of ESCC treatment and the hospital volume value at the lowest risk of all-cause mortality after esophagectomy in China.

Aim: To investigate the prognostic value of hospital volume for assessing postoperative long-term survival of ESCC patients in China.

Background: Recently, Trichloroethylene (TCE) induced TCE hypersensitivity syndrome (THS) has attracted the attention of many researchers in the field of environmental and occupational health. Studies have revealed that Human leukocyte antigen (HLA) polymorphisms were the important genetic determinants of the diseases, but the potential molecular mechanism remains unclear.

Objective: This study aimed to investigate the association between THS and HLA at the molecular level.

Background: Gastric cardia adenocarcinoma (GCA), which has been classified as type II adenocarcinoma of the esophagogastric junction in western countries, is of similar geographic distribution with esophageal squamous cell carcinoma in China, and even referred as "sister cancer" by Chinese oncologists. The molecular mechanism for GCA is largely unknown. Recent studies have shown that decreased expression of E-cadherin is associated with the invasion and metastasis of multiple cancers.

Piwi-interacting RNAs (piRNAs) dysregulation occurs frequently in extensive cancers. However, there was no report about piRNA expression in esophageal cancer (EC). In this study, the expression levels of piR-823 and DNMT1, DNMT3A, DNMT3B were detected in 54 pairs of ESCC tissues and adjacent normal tissues using the quantitative real-time polymerase chain reaction method.

This study was performed to compare the treatment status between older (≥65 years) and younger adults (18-64 years) with severe mental illness (SMI) and explore factors associated with treatment status in rural China. Persons with SMI were identified in one mental health survey in 2015 in 6 townships of Xinjin County, Chengdu, China. Logistic regressions were conducted to explore factors associated with treatment status.

We analyzed 52 pollen samples of surface soils from the southern slope of western Tian-shan, China, to understand the relationship between the surface pollen and modern vegetation, and the significance of the Artemisia/Chenopodiaceae (A/C). The results showed that there were five vegetation zones from the mountain top to the foot, i.e.

The serine peptidase inhibitor, Kunitz type 1 antisense RNA1 (), a long non-coding RNA , has been linked to cancer progression. In this study, we aimed to explore the expression in matched esophageal squamous cell carcinoma (ESCC) and normal tissues, and analyze the potential correlations of expression with clinicopathological characteristics, in order to evaluate its prognosis and therapeutic value. SPINT1-AS1 expression was detected in 99 cases of matched ESCC and normal tissues samples using the quantitative real-time polymerase chain reaction method.

Background: Our previous studies demonstrate that the major histocompatibility complex (MHC) is associated with the progression of esophageal squamous cell carcinoma (ESCC). HLA-DQA1, which belongs to the MHC Class II family, may be a potential biomarker in ESCC progression. However, the association between HLA-DQA1 and ESCC in high-incidence area of northern China has not been well characterized.

Self-incompatibility (SI) is a type of reproductive barrier within plant species and is one of the mechanisms for the formation and maintenance of the high diversity and adaptation of angiosperm species. Approximately 40% of flowering plants are SI species, while only 10% of orchid species are self-incompatible. Intriguingly, as one of the largest genera in Orchidaceae, 72% of species are self-incompatible, accounting for nearly half of the reported SI species in orchids, suggesting that SI contributes to the high diversity of orchid species.

Annually, about 70% of the streams in the Changbai Mountains are frosted during November to April, with manifest seasonal freeze-thaw characters. By using monoculture and mixing leaf litters of Tilia amurensis, Acer mono and Quecus mongolica, this research attempted to disentangle the relationship between leaf litter decomposition and colonization of macroinvertebrates in the stream during early frost period. A 35-day investigation was carried out in a headwater stream of the Changbai Mountains.

Objective: : This study aims to investigate the truth-telling status and the relevant factors of esophageal squamous cell carcinoma (ESCC) patients in Henan, China.

Methods: : A cross-sectional study from April to June 2015 using questionnaires was given to 301 family members of hospitalized ESCC patients based in three affiliated hospitals of Zhengzhou University (i.e.

Orchids make up about 10% of all seed plant species, have great economical value, and are of specific scientific interest because of their renowned flowers and ecological adaptations. Here, we report the first draft genome sequence of a lithophytic orchid, Dendrobium catenatum. We predict 28,910 protein-coding genes, and find evidence of a whole genome duplication shared with Phalaenopsis.

A bacterial strain YHl that used p-tert-Butylcatechol (TBC) as the sole carbon and energy source was isolated from the activated sludge of the wastewater treatment plant of a chemical factory. The strain was identified as Pseudomonas corrugate by morphological characteristics, physiological and biochemical properties, BIOLOG and the 16S rDNA sequence analysis. The degration rate of TBC was above 82% with an initial concentration of 500 mg.

Objective: To explore the effects of iptkalim on myocardial enzymes and free radicals metabolism with hypoxic pulmonary hypertension (HPH), in order to provide evidence for the mechanism of iptkalim on clinical treat.

Methods: 110 young men stayed at high altitude above 5 000 m were divided into iptkalim group (n = 74) and placebo group (n = 36), aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (gamma-GT), creatine kinase (CK), lactate dehydrogenase (LDH), superoxide dismutase (SOD), malonaldehyde (MDA), nitric oxide(NO) and nitric oxide synthase(NOS) were detected before and after took medicines for 6 mouths.

  • A study in Ji'an county, China, assessed cataract prevalence, surgical outcomes, and their social impact on individuals aged 50 and above, finding a cataract prevalence of 23.11%.
  • Among the 5010 individuals examined, cataract surgeries mostly involved modern techniques with a relatively low surgical coverage rate of 32.29% and a social burden of 3.83% due to cataract blindness.
  • Results indicated that older females are at higher risk, and many operated eyes did not achieve optimal visual acuity due to issues like post-capsular opacity and refractive errors.
