OBJECTIVETo prospectively study the relationship between risk factors and stroke incidence and mortality in the Chinese elderly.

METHODSAn analytic study in a cohort population of 1,268 male retired cadres in a military setting. A health-screening program was carried out for all cadres aged 55 years or older in Xi'an in February 1987. Baseline data on smoking, cholesterol, triglyceride, blood pressure, body mass index (BMI), histories of hypertension, hyperlipidemia and coronary heart disease (CHD), stroke, diabetes and family histories of cardiovascular disease were investigated. Main outcome measures were stroke incidence, stroke and all-cause mortality.

RESULTSThe cohort was followed up until June 30, 2001 and a total number of follow-up person-year was 15,546. During the follow-up period, there were 113 new stroke cases identified and the adjusted incidence was 727 per 100,000 person-year. Forty-five deaths were due to stroke and the adjusted mortality was 289 per 100,000 person-year. Using Cox model analysis, after adjustment on age, total cholesterol, triglyceride, smoking, drinking and physical exercise, we noticed that the systolic pressure, BMI, history of CHD and hyperlipidemia were independent risk factors for stroke incidence and morality.

CONCLUSIONThe incidence and mortality of stroke in this cohort were lower than those in the same age group of general population. Monitoring and controlling body mass index and blood pressure level seemed to be important factors for the prevention of stroke in the elderly.

OBJECTIVETo evaluate the feasibility and efficacy of a new method of endoscopic esophageal variceal ligation combined with partial splenic embolization (EVL-PSE) for the patients with portal hypertension.

METHODSFrom May 1999 to February 2003, sixty-eight patients with portal hypertension underwent EVL-PSE, and hemodynamics of the portal trunk (PT), the left gastric vein and azygos vein, including maximum velocity, flow volume, vein diameter, were assessed using color ultrasound Doppler.

RESULTSThe esophageal varices and hypersplenism were greatly ameliorated after operation in patients who had undergone EVL-PSE. Postoperative portal trunk flow volume and velocity were significantly reduced (P < 0.05), and flow volume of the left gastric vein as well as the azygos vein were also reduced after operation. During 2 - 24-month follow-up, no recurrent bleeding was found.

CONCLUSIONSEVL-PSE is less traumatic with less complications, and results in marked eradication of esophageal varices, it can be carried out safely in the clinical treatment for patients with portal hypertension.

OBJECTIVETo investigate the rational digestive reconstruction after total gastrectomy for gastric malignancy.

METHODSThree types of digestive reconstruction were performed after total gastrectomy in 189 cases with gastric carcinoma. The operating time, morbidity and mortality, food intake, digestive tract symptoms, nutritional status at 1 and 3 years after surgery and 1-, 3-, 5-year cumulative survival were compared.

RESULTSThere were no significant differences among the three procedures in operative morbidity and mortality, postoperative food intake, nutritional status (Hemoglobin, total protein and labium), and incidences of diarrhea and dumping syndrome (P > 0.05). The overall 1-, 3-, 5-year survival rates were 75.3%, 38.2% and 20.5% respectively, and there were no significant differences among the three groups (P > 0.05). Orr-type and P-type esophagojejunostomy had an advantage of anti-esophageal reflux, and were obviously superior to Moynihan-type anastomosis (P< 0.01). Compared with P-type reconstruction, Orr-type reconstruction was simpler with shorter operating time, and less complications.

CONCLUSIONSOrr-type Roux-en-Y esophagojejunostomy can be recommended as an adaptable method of digestive reconstruction after total gastrectomy for gastric cancer because of its avoiding reflux esophagitis, maintaining better nutritional status and quality of life, and simpler procedure.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.
