解读《食品容器、包装材料用添加剂使用卫生标准》

食品安全问题一直备受人们关注,然而食品包装作为食品的"隐形添加剂",往往被人忽视.在生活中,很多包装材料及其使用的添加剂都可能含有有毒有害物质,由于这些物质的释放和迁移大部分是隐、慢性的,并且有些包装材料或使用的添加剂只有在一定时间、温度、湿度、酸碱度等条件下才会释放有毒有害物质,因此不易被察觉.

　Peptic ulcer is a common and frequently encountered disease. H2 receptor blocker and several other drugs have been used in treating peptic ulcer (PU) since many years ago, but there still remain a rather large number of intractable ulcer and recurrent ulcer. Recently the discovery of Helicobacter pylori (HP), as well as the relationship between HP and PU relapse was confirmed, but there still lacks of perfect therapeutic program for anti-HP infection(1). From June 1993 to August 1996, we used a pure TCM preparation Moluo Yangping granule (摩罗疡平冲剂, MYG) in treating 64 PU patients, and satisfactory results have been obtained. The report is as follows.METHODSPatient Selection　　According to the diagnostic standard of PU worked out by Ministry of Health in “Guiding Principles for Clinical Study of New Chinese Drugs”, 126 PU patients with typical symptoms and signs were enrolled, who were confirmed to have PU before treatment with biopsy sample performed urease quick diagnostic method under gastroscopy, and pathological special stain were microscopically examined to verify the HP infection. Basal acid output (BAO), maximal acid output (MAO), peak acid output (PAO) and the amount of parietal cells were measured in all the patients.

治疗恶性肿瘤寒凉药不可多

为什么治疗恶性肿瘤寒凉药不可多用，其原因有二，一是恶性肿瘤的发病及发展中、或在手术后、放化疗、介入等方法治疗后，会产生气血津液大量的亏损，甚至逐渐形成阳虚。二是患者素体阳虚或感受寒邪的入侵而造成恶性肿瘤。总结了该病虚寒者多，实热者少，正虚邪实者多，单独邪实者少，所以治疗该病是扶正祛邪者多，单独泻实者少，可以看到，伤气、伤阳的寒凉药即不可多用了。文中分别列有温阳兼解毒法、温阳兼化痰法、温阳兼化瘀法、温阳兼软坚散结法的不同应用，其中列举了四种方法中的佳常用药物，后以温阳法治疗胃癌手术后，中阳损伤的实际案例。

Since 1995, the Chinese herbal medicine for supplementing qi and activating blood circulation combined with injection of ahylsantinfarctase into the femoral artery has been used in 28 cases of diabetes complicated with gangrene and ulcer of the foot, with quite good therapeutic effects as reported in the following.

Both therapies of traditional crude herb moxibustion and drug acupoint application were used in 209 cases of allergic asthma to compare their long-term and short-term therapeutic effects and to analyze the relationship between clinic therapeutic effects of both therapies and differential types of the disease. The results showed that the short-term total effective rate in the group of drug acupoint application was higher than that in the group of traditional crude herb moxibustion, the therapeutic effects of drug acupoint application being closely related to differential types. Analysis also shows the best short-term therapeutic effect was in the type of heat in the lung while the poorest effect in the type of deficiency of the kidney-yang.

Fengchi (GB 20) is a point of the Gallbladder Meridian of Foot-Shaoyang. It is commonly used in clinical practice. According to the literature of traditional Chinese medicine, Fengchi (GB 20) can be used to treat many diseases, especially for the disorders caused by pathogenic wind. The indications include common cold, headache, cervical spondylosis, trigeminal neuralgia, hypertension, apoplexy, neurasthenia, epilepsy, optic atrophy, tinnitus, myopia, and painful heel etc. The viewpoints of different schools varies on the needling angle and depth at Fengchi (GB 20). Perpendicularly puncturing 0.3-0.7cun deep is recorded in most of the ancient books. Puncturing to a depth of 1.2 cun is mentioned in Fundamentals of Acupuncture and Moxibustion (针灸资生经) and Compendium of Acupuncture and Moxibustion (针灸大成). Jiang Yijun, a modern famous acupuncturist, holds that the depth of needle insertion at Fengchi (GB 20) should be varied in different individuals and different diseases. In general, deep puncture should be adopted for the disease in deep location, shallow puncture for the disease in shallow area, and tapping with plum-blossom needle for the disease on the skin. These will be introduced below.

Huang Qi Gu Jing Yin (HQGJY黄芪固精饮decoction of Astragalus root for Strengthening the Essence) was used in a controlled clinical trial for treatment of senile benign renal arteriolosclerosis. In the therapeutic group (n=30), cure, marked effect and no effect were obtained respectively in 18 (60%), 9 (30%) and 3 (10%) cases with the total effective rate being 90%; the corresponding figures in the control group (n=30) were 10 (33.3%), 9 (30%) and 11 (36.7%) with the total effective rate being 63.3%. The significant difference (P<0.01) between the two groups demonstrated that HQGJY is an effective agent for treatment of the disease.

The therapeutic principle of clearing away the heart-heat to induce tranquilization was adopted in 107 middle-aged and senile patients with ventricular premature beat of coronary heart disease on the basis of pathogenic features of phlegm, heat, blood stasis and deficiency in this condition. Qing Xin An Shen Fang (清心安神方a formula for clearing away the heart-heat to induce tranquilization) was used in the treatment group and compared with mexiletine and Fu Fang Dan Shen Tablets (复方丹参片Compound Salvia Tablets) used in the control group. The results turned to be that the markedly effective rate was 85.1% and the total effective rate 96.3% in the treated group, better than that in the control group, with the former having a good antihypertensive and antihyperlipemic effect and an effect of improving microcirculation and clinical symptoms.

Diabetic neuropathy (DN) is one of the common complications of diabetes mellitus (DM), its incidence can be as high as over 90%. The lesion can involve the sensory, motor and vegetative nerves. As a whole, the lesion can be divided into symmetric multiple neuropathy and asymmetric single neuropathy. Because the pathogenesis of the disease is not clear, no specific therapy is available so far. Besides control of blood sugar level, vitamin B, vasodilators and analgesics are often used in Western medicine for expectant treatment. Basic studies on chronic complications of DM show that aldose reductase and non-enzymatic glycosylation of protein are factors initiating the pathological changes, inhibitors against them have been tested in experimental studies and proved effective. Unfortunately, they are not used clinically due to severe side effects. Screening for herbal drugs to treat DN is still a popular trend in the TCM circle.

There are three principles which need to be grasped in the clinical use of Chinese drugs in the treatment of hypertension: Combination of syndrome differentiation in TCM with disease-differentiation in western medicine; combination of the theory of TCM with the results of modern pharmacological researches; and combination of symptom improving, blood-pressure reducing with complications preventing measures.Use of Chinese Drugs Based on the Western Medical Stages of Hypertension Patients should be classified for clinical stages of hypertension according to western medical criteria before TCM treatment program is made. For instance, in hypertension patients, apart from high blood pressure, there may also be other symptoms such as headache, dizziness, distending sensation in the head, stiff sensation in the neck, dim eyesight, tinnitus, poor memory, inability to concentrate the mind, insomnia, disphoria, general weakness, numbness of the four limbs, and palpitation. In some patients, these symptoms may not always be directly related to hypertension. In these cases, treatment for reducing blood pressure may not be taken into consideration, and the treatment based on general differentiation of the symptoms may serve the purpose. Only after the differential use of Chinese drugs shows no obvious improvement of the symptoms and high blood pressure, the treatment will be aimed at hypertension per se. When Chinese drugs alone can not reduce blood pressure, western medicine is often used in combination to reduce blood pressure, blood lipids and uric acid, correct water-electrolyte metabolism, and improve blood rheology. The combined Chinese and western medical treatment can make up each other's deficiencies so as to give better therapeutic effects.

Blood-letting therapy is extensively used in acupuncture clinic. In recent years, the author has applied blood-letting therapy to treat various kinds of diseases, with satisfactory therapeutic results reported in the following.

Large and small doses of drugs for improving blood circulation and removing blood stasis were used in model rats to treat mild chronic hepatic damage induced by carbon tetrachloride (CCl4). The results show that large dose of Dang Gui (当归 Radix Angelicae Sinensis) and Dan Shen (丹参 Radix Salviae Miltiorrhizae) (drugs for regulating blood flow) and small dose of Yu Jin (郁金 Radix Curcumae) and Niu Xi (牛膝 Radix Achyranthis Bidentatae) (drugs for activating blood flow) can significantly elevate the activity of SOD (P<0.05) and/or lower the T/K ratio, markedly reduce the MDA content (P<0.05 or P<0.01) and significantly decrease the activities of ALT and AST (P<0.05 or P<0.01), demonstrating that these drugs are effective in combating oxygen free radicals (OFR) in chronic liver damage. On the contrary, large dose of Tu Bie Chong (土鳖虫 Eupolyphaga seu Steleophaga) and E Zhu (莪术 Rhizoma Curcumae) (drugs for removing blood stasis) tend to increase the ALT and AST (P<0.05) activities. The results suggest that the synergism of elevation of the SOD activity and reduction of T/K ratio contributes to the action of drugs for improving blood circulation and removing blood stasis in combating the liver damage induced by CCl4.
