Affiliated Zhongda Hospital, Southeast University, Cancer Center Director, Clinical Nutrition renowned cancer expert Professor Li Suyi intervention that nutrition is very important for cancer patients. Critical moment, nutrition therapy can give cancer patients "survivor" nutritional support for patients with cancer treatment can help patients successfully completed a variety of tumor treatment, to improve the quality of life of patients and prolong survival.

Experts pointed out that during the period of radiotherapy, patients and increased energy consumption, coupled with gastrointestinal reactions, often forced to interrupt treatment, nutritional support therapy, the patient's tolerance can ensure the smooth completion of treatment. As nutritional support may promote tumor cell proliferation, the quiescent into mitosis, while in the division of tumor cells increased the sensitivity of chemotherapy, and also enhance the treatment's sense.

Professor Li Suyi reminded that cancer is usually caused by metabolic disorders, as most cancer patients die of malnutrition reason, even more than the disease itself against malnutrition.

Forget ECG service antipsychotics

In clinical work, we often encounter long-term use of antipsychotic drugs in patients and family members ignore the return visit to the hospital regularly, advising them on a regular basis ECG, often without was prescribed a variety of reasons, resulting in serious adverse reactions, sometimes even life-threatening.

As we all know that drugs are some serious side effects, such as cardiac side effects. Whether traditional or novel antipsychotics, can lead to heart adverse reactions, ECG has been caused to predict cardiac side effects of antipsychotic drugs, an effective tool to prevent sudden death.

Antipsychotic-induced ECG abnormalities, including bradycardia, tachycardia, ECG changes, conduction block and so on. Current antipsychotic-induced QTc interval prolongation more concerned about.
QT interval refers to ventricular repolarization from the extreme end than the beginning of time, QTc interval is adjusted by the formula of QT interval. QT interval of the normal range of 320 ~ 440 ms, QTc interval prolongation may lead to syncope, ventricular fibrillation cardiac arrest and sudden death, great harm to life.

Many antipsychotic drugs can cause
QTc interval prolongation, such as chlorpromazine, clozapine, haloperidol and so on. It is reported that clozapine induced QTc interval prolongation 71.43% incidence rate, the elderly and associated with cardiovascular and cerebrovascular diseases, mental illnesses are at high risk of sudden death, the mentally ill, even taking moderate doses of antipsychotics, sudden death risk is also relatively large.

Therefore, the long-term use in patients with antipsychotics should regularly return visit to the hospital to conduct ECG monitoring, prevention of antipsychotic-induced adverse cardiac events. The current proposal is: 1. A comprehensive assessment of the baseline ECG results. 2. The treatment of periodic ECG and electrolytes. In case of tachycardia, dizziness, syncope, or epilepsy, should be immediately electrocardiogram. 3. If the ECG report tips
QT interval more than 500 milliseconds, it is recommended to immediately stop the anti-psychotic drugs.

Less than 5 cm in diameter may be conservative treatment of abdominal aortic aneurysm

Old Lee touched his abdomen with a mass, and with the heart beat, to the hospital, the doctors let him do the color Doppler examination, found his limited expansion of the abdominal aorta, 4 cm in diameter, formed abdominal aortic aneurysm, and the doctor 1 every six months he color Doppler examination, observation of tumor size, even when it is necessary to do surgery or interventional therapy.

Abdominal aortic aneurysm is a common disease, arterial distensibility, hypertension and atherosclerosis is the underlying causes of aneurysm, atherosclerosis, so that wall elasticity, weak part of the blood flow impact in the gradual enlargement, prominent, the formation of abdominal aortic aneurysm.

Normal abdominal aorta about 2 cm in diameter, if the abdominal aorta diameter greater than 3 cm or in part, is 1.5 times greater than the remote, that is known as abdominal aortic aneurysms.

Most abdominal aortic aneurysms have no symptoms, many in the medical examination found that some pulsating abdominal mass. Color Doppler ultrasound examination can clearly show that vascular thrombosis in shape and so on diagnosis of abdominal aortic aneurysm valuable diagnostic method for the current selection. CT and MRI can show the tumor and the relationship between retroperitoneal and spine, but costs more.

Abdominal aortic aneurysm is like a time bomb body, once broken, the death rate as high as 50% to 80%, more than 5cm of significantly increased risk of aneurysm rupture, a sudden severe lower abdominal or back pain that threatened to burst Aneurysm , need immediate medical attention.

Abdominal aortic aneurysm less than 5 cm in diameter, you can take a conservative treatment to control blood pressure, do a color Doppler ultrasound examination every six months to observe the changes of aneurysm. Symptoms or if the aneurysm is greater than 5 cm in diameter, should take surgery or interventional therapy.

Diabetes, fatty liver is a train

Sunday, March 9th, 2008

Fatty liver is a straight through car diabetes
At present, the number of non-alcoholic fatty liver disease has reached 9
000 million people, is the reserve army of diabetes, of which 50% of people may develop diabetes. Direct impact on the degree of fatty liver systemic disorder of lipid metabolism and glucose metabolism in the occurrence and development of type 2 diabetes and cardiovascular disease, diabetes, an important factor. Can be said that fatty liver is insulin resistance signal, occurrence of diabetes is a through train.

Early detection, early control is the prevention and treatment of fatty liver is very important tool. If adequate attention, reasonable exercise and lifestyle changes will make the body function back to normal. Recent weight gain, postprandial dizziness, poor concentration, moving the fatigue, abdominal dull pain, or discomfort and other symptoms, which are lipid disorders and the clinical signs of fatty liver, if the examination revealed elevated liver enzymes, blood lipids, glucose should be timely liver B-ultrasound, CT or MRI when necessary (MRI) examination in order to accurately determine the severity of fatty liver and liver fat content. At the same time, should go to an experienced specialist to conduct a comprehensive inspection, because the time associated with fatty liver may have abnormal glucose tolerance, but in general physical examination is difficult to find time to carry out glucose tolerance test and insulin secretion function tests to detect them early signs. In patients with fatty liver, 50%
Patients associated with hyperinsulinemia and diabetes, pre-show, the importance of early attention, 60% to 80% of patients can be saved from the brink back against diabetes and cardiovascular disease, enjoying a normal life .

Determining the quality of life of bladder condition

Some men experience sexual life, such experience: When the residual amount of urine within the bladder, urinary makes little meaning, it will increase sexual excitement in continuing to maintain an erection when sexual ability.
Therefore, weaker sexual function of men, not to urinate before intercourse or drink warm water after urination, weak tea, about half an hour later when a little means of urine, and then started having sex.
For men, premature ejaculation tend to, then contrast, have to urinate before sex. Because even in patients with premature ejaculation only weak stimulation by the bladder expansion will induce ejaculation center ejaculation caused high excitement.
For women, the right amount of urine within the bladder, but also slightly increase the role of nervous excitement. Urinate after sex, sexual intercourse can be washed into the urethra to the pathogen, prevent urinary tract infections.
Referred to here to stay urine is to retain a small amount of urine, urinary intention to slight suitable, not too much. Because for a man, a large number of urine accumulated in the bladder, the pressure around the nerves, increases the excitability of nerve, penis erection, and the desire to have sexual intercourse. However, the nerve center for by the "urgency" of the interference, it is difficult to achieve orgasm. Suppression of urine at this time if the best intention, sexual intercourse will speed up the action, although sperm can still be discharged, but it affects the pleasure of ejaculation. If the time to stop intercourse immediately to urinate, urinating soon after the contraction of the bladder, combined with genital disengagement time is long, the penis will naturally weak, if middle-aged man, think of an erection is not so easy. So much urine sample will also affect the sex life, or even sexual arousal may lead to urinary incontinence during intercourse.
