Reduction of adrenocorticotropic hormone (ACTH) and cortisol in drug addicts treated by acupuncture and electrical stimulation (AES).

Forty-two heroin addicts and 31 normal persons were examined for the effect of acupuncture and electrical stimulation (AES) on plasma ACTH, cortisol and cyclic-AMP levels. Both ACTH and cortisol levels were reduced significantly in the addicts after treatment whereas no such significant reduction was observed in the normals. Plasma cyclic-AMP level was not affected in either group. Taken together, results from the present study suggest that the mechanism of AES in the treatment of addiction may have a neuroendocrinological basis. This hypothesis is particularly attractive in view of the isolation of opiate-like peptides from the brain.     

Effects of eating an uncooked vegetable diet for 1 week

Biochemical and metabolic indicators were monitored in a group of volunteers suffering from a variety of chronic illnesses participating in a week's course on a special uncooked vegetable diet, known as "living food". Unmatched healthy controls ate the same diet cooked for 2 min in a microwave oven. After 1 week on the regimen, serum protein and urea contents decreased and alanine aminotransferase (ALAT) activity increased in both groups, although all within the normal range. Blood glucose increased in both groups to slightly above normal limits but total serum cholesterol dropped about 1 mmol/l from normal starting levels. Serum tocopherol and retinol increased only in the group eating the uncooked diet. In both groups urinary sodium dropped drastically without a significant change in potassium. Serum and urinary phenol and p-cresol diminished also significantly. It is concluded that this vegetable diet may be of some benefit in the short term but any longer-term use requires evaluation.     

Correlation analysis between plasma atrial natriuretic peptide and cardiac function in blood deficiency syndrome]

The function of ANP in the cardiovascular regulation is very similar with the TCM theory of "the Heart governs blood circulation". Using the method of cardiac impedance to check cardiac output and the method of radioimmunoassay (RIA) to check plasma ANP, the result showed that in the status of Blood Deficiency Syndrome, cardiac function was impaired, there were reduced kinemia and stroke volume, as well as markedly raised plasma ANP and peripheral resistance. The above-mentioned indexes were significantly different from those of normal group (P < 0.01). Using multivariate regression analysis, cardiac output was negatively correlated with the plasma ANP (P < 0.05). 23 cases with Blood Deficiency Syndrome showed normal hemoglobin, but an evidently changed cardiac output and plasma ANP were closely related with the level of the Blood Deficiency. Both parameters might serve as the objective basis to reflect the level of Blood Deficiency to facilitate the clinical diagnosis of the patient.     

The standardized mortality ratio and life expectancy.

This paper develops a theoretical relation between the standardized mortality ratio (SMR) and the expected years of life and establishes a regression equation for easy conversion between these two statistics. The mathematical expression of the derived relation is an approximation, requiring an assumption of constant age-specific mortality ratios. It underestimates the "true" value calculated based on life table technique when the age-specific mortality ratios increase with age. This equation provides a conservative method to estimate the expected years of life for cohort mortality studies and facilitates an assessment of the impact of work-related factors on the length of life of the worker. It also allows one to convert the SMR to life expectancy in smaller studies whose sole objective is to determine the SMR in a working population. A 1% decrease (or increase) in the standardized mortality ratio will result in 0.1373 years increased (or decreased) life expectancy based on white male data for the US population. Furthermore, with data from 14 large oil refinery and chemical worker cohorts of white males, the "derived" expected years of life based on the regression equation closely predicts the corresponding value calculated using a standard life table technique. This statistical equation is expected to have practical applications when used in conjunction with the SMR to provide an approximate measure of life expectancy, a term and statistic familiar to most lay people.     

Fast detoxification of heroin addicts by acupuncture and electrical stimulation (AES) in combination with naloxone

Detoxification can be accomplished more rapidly by first "flushing" the opiates from the receptor sites. Naloxone, a short acting antagonist displaces opiates from the receptor sites and such displacement precipitates an abstinence syndrome. Recently, a method of using acupuncture and electrical stimulation (AES) in combination with naloxone for fast detoxification was reported. This technique was applied to 50 cases of heroin addicts. Forty-one were detoxified. There were nine failures. Of the 41 cases, 18 patients were sent to rehabilitation centres and did not experience abstinence symptoms. Six were sent out of Hong Kong where heroin is not available, and two others did not go to a rehabilitation centre but still abstained. The other 15 were presumed to be on the drug. It is advocated that AES increases endorphin and relieves abstinence syndrome, but also at the same time inhibits the autonomic nervous system, mainly the parasympathetic nervous system. The technique does not stop the craving, therefore after detoxification, the patients should be sent for psycho-social rehabilitation, or alternatively be put on long acting antagonist.

慢性鼻窦炎鼻息肉围手术前期处理对术中出血影响的观察

OBJECTIVE: To explore the method of reducing bleeding during endoscopic sinus surgery for chronic sinusitis and nasal polyp. METHODS: Bleeding during surgery and the effective rate of two groups patients with chronic sinusitis and nasal polyp were compared (68 cases in group A with preoperative treatment, 30 cases in group B without preoperative treatment). RESULTS: The effective rate between group A(91.2%) and group B (80%) is of significant difference (F = 8.617, P = 0.026); The volume of bleeding during surgery between group A that is (53.2 +/- 41.8) ml and group B that is (97.2 +/- 59.0) ml is of significant difference (F = 27.946, P = 0.002). CONCLUSIONS: Controlling the inflammatory reaction of chronic sinusitis and nasal polyp by preoperative treatment is the most important factor to reduce bleeding while undergoing endoscopic sinus surgery. However, the followings are also important factors to reduce bleeding in endoscopic sinus surgery, such as adequate use of vasoconstrictor in the middle nasal meatus during surgery, the use of deliberate hypotension during surgery, controlling the high risk factors by preoperative treatment and reducing trauma during surgery, etc.
