[Effect of Diurnal Temperature Range on the Number of Residents Hospitalized Due to Stroke in Lanzhou].
Zhongguo Yi Xue Ke Xue Yuan Xue Bao
December 2023
Article Synopsis
- The study examines the link between diurnal temperature range (DTR) and stroke hospitalizations in Lanzhou from 2014 to 2019, aiming to understand how temperature variations might influence stroke incidents and to help shape prevention strategies.
- An analysis found a nonlinear relationship where low DTR, particularly around 4.5 ℃, had a greater effect on stroke admissions, especially for males and individuals under 65 years old, showing a cumulative lag effect.
- Results indicate that both low and high levels of DTR impact stroke patient hospitalization, but low DTR levels are slightly more detrimental, highlighting the need for targeted protective measures for vulnerable populations.
[Air Temperature Affects the Hospital Admission for Cardiovascular Diseases among Rural Residents in Dingxi City].
Zhongguo Yi Xue Ke Xue Yuan Xue Bao
April 2022
Article Synopsis
- - The study investigated how air temperature affects hospitalizations for cardiovascular diseases among rural residents in Dingxi city, analyzing data from 2018 to 2019 using distributed lag non-linear models.
- - A non-linear, bell-shaped relationship was found between air temperature and hospitalizations, with low temperatures (like -7°C and 0°C) having cumulative lag effects, meaning their impact on hospital admissions could last several days after exposure.
- - Specific results showed significant peak hospitalization rates for ischemic heart disease and heart rhythm disorders at different temperature thresholds, with moderately high temperatures (17°C to 21°C) also leading to increased hospitalizations on the same day.
[Effect of Air Pollution on Emergency Room Visits for Respiratory Diseases in Lanzhou].

June 2021
Objective To explore the effect of air pollution on the number of emergency room visits for respiratory diseases in residents at different ages and its seasonal changes in Lanzhou,so as to provide a scientific basis for the early prevention of respiratory diseases in Lanzhou. Methods The daily number of emergency room visits for respiratory diseases in three class A hospitals in Lanzhou from January 1,2013 to December 31,2017,as well as the air pollutants and meteorological data of Lanzhou in the same period,was collected.After controlling the confounding factors including long-term trend of time,meteorological factors and day-of-week effect using a generalized additive model,we analyzed the relationships between air pollutants and the daily number of emergency room visits for respiratory diseases,and explored whether there was a lag effect of air pollutants.

- The study explores the link between patients' personality traits and their recovery outcomes after total knee arthroplasty, focusing on psychological factors that may influence postoperative results.
- Researchers surveyed 387 patients using the Eysenck Personality Questionnaire (EPQ) before and after surgery, assessing their satisfaction and functional improvement with standardized instruments.
- Results showed that extraversion is correlated with better outcomes, while higher neuroticism, particularly among younger and female patients, is linked to worse recovery experiences and lower satisfaction rates.*
Article Synopsis
- The study aimed to assess how effective muscle relaxants and celecoxib are for early recovery after total knee arthroplasty (TKA) in 150 patients divided into three groups.
- Participants received either both muscle relaxants and celecoxib, muscle relaxants only, or a placebo for 2 weeks.
- Results showed that the group receiving muscle relaxants and celecoxib had better pain relief, indicating that this combination enhances recovery post-surgery.
Article Synopsis
- The study evaluates the use of antibiotic-loaded cement articulating spacers created from a self-made mold system in treating infected total hip arthroplasties through a two-stage revision process.
- Out of 127 patients treated, the infection control rate was high at 96.3% after the first stage and 94.4% overall, with complication rates being relatively low.
- The findings suggest that this method is effective, offering advantages such as good reproducibility, improved joint function, high patient satisfaction (93.5%), and reduced complications during revision.
Article Synopsis
- The study aimed to compare two surgical methods—proximal femoral resection and subtrochanteric osteotomy—for treating severe cases of congenital dislocated hip (Crowe's IV) with total hip arthroplasty.
- Sixty patients were involved, with results indicating no significant differences in leg length discrepancies between the two methods, but higher complication rates in the proximal femoral resection group.
- The subtrochanteric osteotomy method not only improved the Harris score (indicating better overall hip function) but also reduced the risk of complications associated with high-riding dislocations.
[Impacted cancellous autograft for reconstructing bone defects of tibial plateau in total knee arthroplasty].
Zhonghua Yi Xue Za Zhi
November 2008
Article Synopsis
- The study aimed to assess a new technique for converting dish-like bone defects into contained defects to improve bone repair during total knee arthroplasty (TKA) for osteoarthritis patients with severe knee deformities.
- The procedure involved 54 patients, where cancellous bone fragments from femur and tibia were used to fill the defects, providing a solid support for the knee prosthesis with successful outcomes.
- Results showed significant improvement in knee function (KSS scores increased from 45.6 to 94.5) with no signs of graft resorption or adverse effects on the prosthesis during a 32.2-month follow-up.
