Preoperatively predicting the lymph node metastasis and prognosis for gastric cancer patients.

The preoperative distinguishment of lymph nodes (LN) with metastasis plays a pivotal role in guiding the surgical extension for gastric cancer (GC). We aim to identify the preparative risk factors for LN metastasis in GC patients. We retrospectively reviewed 424 patients who underwent radical GC resection in our medical center between Jan 2011 and Dec 2018.

Trends and Projections of Stomach Cancer Incidence in Hong Kong: A Population-Based Study.

Objectives: The burden of stomach cancer remains high in Hong Kong. We sought to evaluate the associations of age, period, and birth cohort with the changing trend in the incidence of stomach cancer and to provide projections through 2030.

Materials And Methods: We performed an age-period-cohort analysis and projections up to 2030 using data from the Hong Kong Cancer Registry.

Assessment of age, period, and cohort effects of lung cancer incidence in Hong Kong and projection up to 2030 based on changing demographics.

The burden of lung cancer in Hong Kong continues to rise. We analyzed trends in lung cancer incidence and associations with age, period, and cohort from 1985 to 2019, made projections up to 2030 and examined the drivers of lung cancer incidence. We used age-period-cohort modeling to estimate age, period, and cohort effects on lung cancer incidence rates in Hong Kong between 1985 and 2019.

Competing risk analysis of primary tracheal carcinoma based on SEER database.

Purpose: To analyze the prognostic factors of primary tracheal carcinoma.

Patients And Methods: All patients of primary tracheal carcinoma were extracted from the Surveillance, Epidemiology, and End Results database during 1973-2015. The potential prognostic factors were analyzed by using the competing risk analysis of R statistical software.

Analysis and preparation of rotational flow mechanism of artificial blood vessel with spiral folds on inner wall.

The swirling motion of blood flow is a widespread physiological flow phenomenon in the human body. The probability of cardiovascular and cerebrovascular diseases could be effectively reduced by swirling blood flow. In this study, first we proposed a new integrated vascular model with spiral folds on the inner wall.

Chemical and optical properties of aerosols and their interrelationship in winter in the megacity Shanghai of China.

A field campaign on air quality was carried out in Shanghai in winter of 2012. The concentrations of NO, NO2, NOx, SO2, CO, and PM2.5 increased during haze formation.

Meteorology and ethnicity as critical factors in HRIPT: Comparing responses between Chinese and Indian ethnicities.

Background: Human repeated insult patch test (HRIPT) is regarded as one of the confirmatory test in determining the safety of skin sensitizers. A number of important factors should be considered when conducting and interpreting the results of the HRIPT.

Objective: To investigate for probable critical factors that influence the results of HRIPT with the same protocol in Shanghai and Mumbai.

Source and deposition of polycyclic aromatic hydrocarbons to Shanghai, China.

Despite recent efforts to investigate the distribution and fate of polycyclic aromatic hydrocarbons (PAHs) in air, water, and soil, very little is known about their temporal change in wet deposition. As a result of increased attention to public health, a large-scale survey on the deposition flux and distribution of PAH contamination in rainwater was urgently conducted in Shanghai, China. In this study, 163 rainwater samples were collected from six sites, and 15 PAH compounds were detected by the use of a simple solid phase microextraction (SPME) technique coupled with gas chromatography-mass spectrometry.
