OBJECTIVE: We aimed to analyze the quality of life (QOL) in adults with allergic rhinitis according to the sensitization profile for relevant aeroallergens in Northern China, investigate the proportion of patients with coexisting asthma, and explore the correlation between QOL of rhinitis patients and the specific IgE level to the causative allergen. METHOD: One hundred and sixty-four allergic rhinitis patients participated in this study, whose clinical history, results of intradermal skin test and serum specific IgE levels to common aeroallergens in North China were collected. QOL was evaluated using the rhinoconjunctivitis quality of life questionnaire (RQLQ). RESULT: QOL of rhinitis patients was worse in those sensitized to tree pollens or weed pollens than those sensitized to house dust mites in Northern China. The proportion of patients with co-existing asthma was lower in tree pollen group than in house dust mite group or weed pollen group, and there was no significant difference between house dust mite group and weed pollen group. There was no significant correlation between QOL of rhinitis patients and the specific IgE level to the causative allergen. CONCLUSION In our study group, QOL of patients with allergic rhinitis varied with the allergen responsible for symptoms, but was not influenced by the specific IgE level to relevant allergen. The proportion of patients with co-existing asthma also varied with different pollen allergens. Rhinitis patients sensitized to weed pollens might be more likely to suffer from asthma than those sensitized to tree pollens.

As a protein originally found in plant pathogenic bacteria, transcription activator-like effectors (TALEs) can be fused with the cleaving domain of restriction endonuclease (For example Fok I) to form artificial nucleases named TALENs. These proteins are dependent on variable numbers of tandem Repeats of TALEs to recognize and bind DNA sequences. Each of these repeats consists of a set of approximately 34 amino acids, composed of about 32 conserved amino acids and 2 highly variable amino acids called repeat variant di-residues (RVDs). RVDs distinguish one TALE from another and can make TALEs have a simple cipher for the one-to-one recognition for proteins and DNA bases. Based on this, in theory, artificially constructed TALENs could recognize and break DNA sites specifically and arbitrarily to perform gene knockout, insertion or modification. We reviewed the development of this technology in multi-level and multi species, and its advantages and disadvantages compared with ZFNs and CRISPR/Cas technology. We also address its special advantages in industrial microbe breeding, vector construction, targeting precision, high efficiency of editing and biological safety.

BACKGROUND: The upward attack of drug-heat is a special type of syndromes of coexistence of cold and heat, it influence the treatment and conversion of the primary disease.OBJECTIVE: To investigate the pathophysiological basis of upward attack of drug-heat.DESIGN: A randomized and controlled observation. SETTING: Department of Traditional Chinese Medicine (TCM) of the People' s Central Hospital of Huizhou City.PARTICIPANTS: Totally 427 patients with cold syndrome, visiting on Department of TCM of the People's Central Hospital of Huizhou City from January 1996 to December 2001, were given warm-heat remedy. Among them 66 cases, 30 males and 36 females, got upward attack of drug-heat during the process of treatment were enrolled. All these subjects, according to their visiting order, at a ratio of 2:1, were chosen as treatment group (44 cases) and control group (22 cases).METHODS: For the patients in treatment group: Rhubarb 6 g was added boiling water 100 mL and soaked for 8 minutes, then the soaking solution was given to the patients, once a day, for 3 days successively. For patients in control group: Table salt 6 g was added boiling water 100 mL for soaking for 8 minutes, after the salt was completely dissolved, the solution was given to the patients, once a day for 3 days successively. The patients of the two groups were at the same time given remedy to treat cold syndrome. The changes of free triiodothyronine (FT3), free thyronine (FT4), high sensitizing thyroid-stimulating hormone (HS-TSH) and cortisol of the patients were detected before and after administration of warm-heat remedy, before and after medication with rhubarb. MAIN OUTCOME MEASURES: ① The changes of the relevant hormones of the patients with upward attack of drug-heat before and after ad ministration of warm-heat remedy. ② The changes of the relevant hormones of the patients with upward attack of drug-heat before and after ad ministration of rhubarb. ③ Comparison of the therapeutic effects in the two groups.RESULTS: All 66 patients involved entered the final result analysis. ①The changes of the relevant hormones of the patients with upward attack of drug-heat before and after administration of warm-heat remedy: FT3 and FT4 were decreased as compared with those before treatment [(2.51±1.20),(6.50±2.30); (10.01±3.21), (15.50±6.31) pmol/L], but HS-TSH and cortisol were increased as compared with those before treatment [(8.25 ±3.75),(4.11±1.75) mU/L; (0.56±0.17), (0.43±0.10) μmol/L]. ② The changes of the relevant hormones of the patients with upward attack of drug-heat before and after administration of rhubarb: FT3 and FT4 ywere increased as compared with those before treatment[(4.71 ±1.56), (2.45±1.25); (14.21 ±4.61),(10.21±3.52) pmol/L], but HS-TSH and cortisol were decreased as compared with those before treatment [(6.24±2.25), (8.35±3.51) mU/L; (0.48±0.10),(0.60±0.17) μmol/L]. ③ Comparison of the therapeutic effects in the two groups: The rate of excellenly effect in treatment group was obviously higher than that in control group (33%, 5%).CONCLUSION: The pathophysiological basis of upward attack of drug heat is stress state of the body, the secretions of the pituitary-thyroid axis play a role of physiological protection, the adrenocortical function is hyperactive, and rhubarb can control this stress state through inhibiting the metabolism of the body.

OBJECTIVE: To observe the effects of ginkgolide (GL) on the cerebral blood flow in dogs. METHODS: Dogs anesthetized with sodium pentobarbital were randomly divided into 5 groups, with 4 dogs in each group. Ginkgolide of 4.86, 14.6 and 43.7 mg/kg and Xingling Granule of 0.22 g/kg were administered by gavage to the dogs in each of 4 groups. The dogs in the other group were administered with edible oil (1 ml/kg) as control group. The cerebral blood flow, systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and electro-cardiogram of the dogs were measured at different times after the administration. RESULTS: Ginkgolide of 4.86, 14.6 and 43.7 mg/kg had no obvious effects on the blood pressure and the heart rate. Ginkgolide of 14.6 and 43.7 mg/kg increased the cerebral blood flow 90 minutes after administration, and ginkgolide of 43.7 mg/kg obviously decreased the cerebral vascular resistance 150 minutes after administration. CONCLUSION: Ginkgolide can increase the cerebral blood flow and decrease the cerebral vascular resistance, and it has no obvious effects on blood pressure and heart rate in dogs.
