慢性乙型肝炎的中医药生态治疗优势

现代医学的生物、心理与社会医学模式特点之一是对以身心疾病为主的现代疾病的预防和治疗 ,更加注重人体的整体性、强调药物作用的多靶点性 ,即整体调节作用。运用中医学的整体观与辩证论治治疗慢性疾病。如肝病的生态治疗就是发挥绿色天然中药复方的多重综合、双向调节功能 ,调动人体的防御机能 ,强调药物作用的多靶点性及整体调节作用以清除病毒、调节免疫、增强抵抗力、恢复肝功能、防止肝炎的慢性纤维化     

10个钨矿职工死因分析

对中南地区10个钨矿1972—1974年入矿(工龄至少1年)的在册职工28453人进行了队列研究。队列成员追访至1989年,死亡2870人,比全国居民死亡率计算的期望值略高(SMR=1.15,95％CI=1.11—1.19);主要是非恶性呼吸道疾病,特别是尘肺(SMR=66.79,95％CI=59.65—73.68)以及与呼吸道疾病相关的肺心病明显超高(SMR=8.19,95％CI=7.42—9.02),比全国居民死亡率高5倍。癌症死亡数在全死因中虽占第一位,但仅鼻咽癌轻度超高(SMR=1.73,95％CI=1.23—2.37),而肺癌死亡率明显偏低(SMR=0.53)。研究结果不支持矽肺与肺癌病因学相关的假说。     

大鼠壁细胞的黏膜刮取式分离方法

采用黏膜刮取式方法，分离大鼠胃黏膜细胞。用相差显微镜、HE染色、电镜、荧光显微镜、免疫细胞化学染色等方法，对壁细胞进行观察和鉴定，并测定了壁细胞直径。结果成功地分离了大鼠胃黏膜细胞，同时证实，壁细胞在所分离的细胞中直径最大。     

Application of median-effect in quantitative analysis of antitumor drugs in vitro

Objective: To analyze quantitatively the synergistic and antagonistic effects of combined oxymatrine (OMT) and 5-fluorouracil (5-GU) on a cell line of human liver cancer (HepG2) with median-effect principle in vitro. Methods: The median-effect principle and MTT method were used in the quantitative analysis of effects of the two drugs. Results: Cytotoxic activity of the individual drugs enhanced as drug concentration increased. As fa=0.41, a CI equal to 1 indicated additivity; fa<0.41, a CI less than 1 indicated synergy; and fa>0.41, a CI greater than 1 indicated antagonism. The sequence of administration did not influence the cytotoxic activity of the combined antitumor drugs. The ratio of drug concentration was a factor that can influence the killing effect. Conclusion: The combined drugs interaction (CI<1) was synergistic at lower concentration and antagonistic at higher concentration. The ratio of drug concentration is a factor that can influence the killing effect. Biography: HE Song(1965–), male, doctor of medicine, associate professor, Chongqing Medical University, majors in gastroenterology.     

崇文区健身器材卫生状况调查

目的：了解健身场所健身器材的卫生状况,为制定卫生标准提供依据。方法：随机抽取14家健身场所的健身器材为调查对象,选择营业高峰期间对其健身器材进行检测。结果：健身俱乐部的健身器材微生物污染程度高于健身附属场所,大型健身场所微生物污染程度明显高于中型、小型场所,操厅的微生物污染相对于有氧区、力量区严重,健身器材中以扶杆、健身球、形体垫子及力量机的微生物污染最为严重。结论：健身器材的微生物污染严重,从业人员缺乏卫生消毒知识,应尽早将健身场所纳入《公共场所卫生管理条例》管理范畴,并制定相应的国家卫生标准,加强对从业人员的卫生宣教,从而有效改善健身器材卫生状况。     

二至丸对四氯化碳所致小鼠ALT升高的预防作用

目的研究二至丸水提物、女贞子、墨旱莲的保肝作用.方法通过检测血清酶学指标,观察二至丸对四氯化碳肝损伤模型的保护作用.结果用药各组均具有降低丙氨酸氨基转移酶(ALT)作用,以二至丸超声水提液和水煎液作用最强,女贞子皂甙和墨旱莲乙酸乙酯提取物的混合物可作为复方保肝降酶的有效部位,但两者不同混合比例的保肝降酶作用应作进一步研究,以寻找最佳配比,达到最佳保肝效果.结论用药各组均具有保肝降酶作用,女贞子皂甙和墨旱莲乙酸乙酯提取物的混合物可作为二至丸复方的保肝降酶的有效部位.     

驼背二种截骨术远期效果对比

作者对６３２例强直性脊柱炎并驼背畸形施行二种脊柱截骨矫治术，对其中１３５例病人进行了６～１０年观察，结果表明：７１例椎弓椎体联合截骨效果较好，驼背复发平均３．２°。而６４例椎板截骨效果略差，驼背平均复发１３．５°。经统计学处理，两者对比有显著的统计学意义（ｐ＜０．０１）。作者认为病变未完全静止，截骨术式的选择，术中身体重心前移未彻底纠正，以及外固定时间过短等是影响远期效果的因素。     

血清TPS浓度在消化道肿瘤中价值的研究

共选择３０例消化道肿瘤病人，其中食管癌，胃癌，大肠癌各１０例，设健康献血者３０例，对两组血清特异型组织多肽抗原浓度进行了检测，结果肿瘤组血清ＴＰＳ浓度明显高于健康人。消化道肿瘤阳性检出经达７０％，其中食管癌８０％，胃癌６０％，大肠癌７０％。消化道肿瘤合并淋巴转移阳性检出率达７６．９％，其中食管癌１００％，胃癌６６．７％，大肠癌７０．０％。随着病程发展，血清ＴＰＳ浓度呈现升高趋势。     

The effect of Coptis chinensis on lipid peroxidation and antioxidases activity in rats]

In order to make a systematic study of the effect of Coptis chinensis on free radicals, the authors used the method that the drug and the brain homogenate of rat were mixed and incubated to investigate the effect of Coptis on lipid peroxidation. The result showed that the malondialdehyde (MDA) product of rat brain homogenate inhibited by 5% Coptis was significantly different from control (P < 0.001). On the basis of the above-mentioned results, the effect of Coptis on lipid peroxidation and diabetes of rats induced by alloxan was investigated. The result showed: (1) The MDA product of both pancreas and liver homogenate in Coptis group was significantly less than that in control and alloxan group (P < 0.01, P < 0.05). (2) Superoxide dismutases (SODs) in erythrocytes activity was the same for all groups (P > 0.50). (3) The blood catalase (CAT) activity in alloxan group markedly decreased compared with control group (P < 0.05), but no significant change between Coptis and alloxan group (P > 0.05). (4) The value of serum glucose in alloxan group was significantly increased in comparing with control group (P < 0.05). There was a trend to decrease the value of serum glucose in Coptis group compared with alloxan group, but no significant difference between two groups (P > 0.05). The experiment indicated that there was very strong inhibitory effect of Coptis to the lipid peroxidation in vitro and in vivo. Coptis could protect rat from diabetes inducing by alloxan and that probably was due to the fact that Coptis was able to inhibit alloxan inducing free radicals.
