Objective To study the relationship of plasma homocysteine (Hcy), polymorphism in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine-?-synthase (CBS) genes, and cerebral infarction in the elderly. Methods 61 elderly patients with first-ever acute cerebral infarction and 57 controls were studied. The plasma Hcy levels were measured using high-performance liquid chromatography-fluorescence detection (HPLC-FD). The polymorphism in MTHFR was determined by a polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion.CBS was determined by amplification refractory mutation system (ARMS). Results The fast plasma Hcy levels were higher in the patient group compared with those in the control group [(13.07?3.96)?mol/L vs (11.51?3.90)?mol/L, P 0.05). There were no differences in the plasma Hcy levels among the different genotypes. Conclusions The MTHFR, CBS gene mutations cannot lead to hyperhomocysteinemia in the elderly patients with acute cerebral infarction. Hyperhomocysteinemia is associated with the independent risk of cerebral infarction, however, mutations only in MTHFR and CBS cannot be ascertained to be independent risk of cerebral infarction in the elderly.

During professor SHAO Jing-ming's academic research and medical practice, his academic opinion of focusing spirit is gradually developed. In terms of nurturing the spirit, attention should be paid on persistence as well as everyday health maintenance and exercise to nurture the spirit of physician. In terms of clinical diagnosis and treatment, patients' psychology, employment and life status should be observed and experienced, which could bring more methods to take essential care of patients' spirit. The treatment should work with psychological counseling, advocating that based on patients' qi and spirit, various forms of treatment methods should be properly used, such as acupuncture or moxibustion or combination of acupuncture and medicine, along with simple acupoint selection and harmony medication. Before clinical treatment of acupuncture, calming the mind is critically emphasized to make a clear diagnosis. During the acupuncture, calming and focusing the mind is necessary as well as emphasizing the details, so acupuncture could be integrated with Chi Gong to create a new warming-sensation technique. In a word, the academic opinion of focusing spirit is shedding an inspiring light upon further study.

Compared with living spray method, it focused on the investigation of different inoculation methods, various inoculation concentration and the influence of different seeding age on soft rot-resistance in Jinxianlian. The results showed that (1) Inoculated with dropping connection, the difference of disease index between A. roxburghii and A. formosanus was grate, so that the disease-resistance could be obviously distinguished. (2) When the inoculation concentration was 1.0 x 10(7) cfu x mL(-1), the difference of disease index was relatively obvious and the disease-resistance could be differentiated well. (3) At the moment of 4-month seeding inoculation, a certain difference of the disease index between A. roxburghii and A. formosanus was existed, so, relatively, it could accurately reflect the resistance difference between various species. With the inoculation of dropping connection, A. roxburghii and A. formosanus of 4-month seeding age was put in the bacteria suspension of inoculation concentration of 1.0 x 10(7) cfu x mL(-1). The identification was taken up after 5 days in the incubator under the condition of 14 h daylight and 28 degrees C. The identification result was conformed with that of the living spray method. To investigate the identification method of in vitro evaluation of soft rot-resistance of Jinxianlian so as to provide the foundation for germplasm utilization and excellent cultivars breeding.
