Cardiovascular community control programs in Beijing.

Cardiovascular community control program in Beijing started in 1969. In the past 20 years, eleven such programs had been established, covering a total population of 750,000. For those programs that have been operating for over 5-10 years, a marked drop in the mortality and morbidity rates of hypertension, stroke and acute myocardial infarction has been observed. It is proposed that this type of community control program should be further expanded in the next ten years so as to materialize the WHO goal of "Health for all by 2000".

Timed overnight sodium and potassium excretion and blood pressure in steel workers in North China.

Three timed overnight urinary sodium (Na), potassium (K) and creatinine measurements, standardized to 8 h, as well as three blood pressures on corresponding consecutive days were obtained on a sample of 90 steel workers (40 men, 50 women) aged 34-56 years in Beijing, North China. For three indices of electrolyte excretion - absolute Na and K output/8 h, Na:K ratio and 8 h creatinine output - the ratios of intra- to inter-individual variations were less than 1.0 for men, but higher for women in contrast to findings for U.S. population groups of similar age. This fact, probably reflecting greater stability of day to day electrolyte intake by Chinese than Americans, enables reasonably precise characterization of dietary electrolyte intakes of individual Chinese, particularly men, with only a few timed overnight urine specimens. With 3-day mean values for each person, nominally significant (i.e. not adjusted for multiple testing) positive simple correlations were found for urinary Na, Na:K and Na:creatinine with blood pressure [both systolic (SBP) and diastolic (DBP)] for men; and women for Na:K with SBP and DBP, but Na:creatinine with SBP only. With control for age, body mass index and pulse in multivariate analyses, only the relationship of Na:K and Na:creatinine to SBP and DBP remained significant for men; a similar, though less strong and consistent, trend was found for women, and K was inversely related to SBP for women. These data are consistent with an association between habitual intake of sodium and risk of hypertension, and also suggest that habitual potassium intake may have a countervailing influence in this regard.

Long term survival of radiotherapy for esophageal cancer: analysis of 1136 patients surviving for more than 5 years.

One thousand one hundred and thirty-six patients surviving for more than five years after radiotherapy were studied. The important prognostic factors are: lesion less than 5 cm in length, lesion located in the upper-third segment and lesion that is radiosensitive. The radiation dose given to long term survivors varies greatly, i.e., 2700 to 9300 rad. Yet, for the sensitive type of lesion, doses lower than 5000 rad could also effect a cure. The delivery of an optimum dose determined by serial examinations during radiotherapy could improve the result of treatment. For local recurrent lesions, the value of a second course of radiation is extremely limited and surgery is the only means to offer a cure. For metastasis in the lymph nodes, radiation offers some hope of cure, although the long term outcome may not be satisfactory. For second primary cancer of the esophagus, aggressive radiation still gives encouraging results.
