Objective To investigate the possible mechanism of direct relaxant effects of propofol on tracheal smooth muscle.Methods Nine Japanese long-ear white rabbits of either sex, weighing 2-3 kg were sacrificed by air embolism. The trachea of each rabbit was removed and cut into six strips of (6-8) mm x (12-15) mm. The tracheal strips were suspended in Kreb' s solution, exposed to 95 % O2 and 5 % CO2 mixture and maintained at 37℃. One end of strip was fixed and the other was connected to a tension monitor through a tension transducer. The experiment was divided into six groups: group I propofol; group Ⅱ propofol + indothelin; group Ⅲp Ⅴ propofol + verapamil and group Ⅵ propofol + glibenclamide. In each group the tracheal strips were precontracted with acetylcholine (10-5 mol? L-1). The strips were then exposed to increasing concentrations of propofol (5 ? 10-3 , 10-2 ,2.5 ? 10-2 , 5 ? 10-2 , 10-1 mg?ml-1 ). At each concentration of propofol, the change in muscle tension was allowed to reach the steady state for 30 min. In group I no other drug was added to the Kreb' s solution besides propofol, while in group Ⅱ-Ⅵ before the effects of propofol were determined, the strips were pretreated with indothelin (10-4 mol? ml-1 ) (in group Ⅱ), L-NAME(10-4 mol?ml-1) (in group Ⅲ), methylene blue (10-5 mol?ml-1) (in group Ⅳ), verapamil (10-5 mol?ml-1) (in group Ⅴ) or glibenclamide (10-5 mol?ml-1) (in group Ⅵ). Results The three concentrations of propofol examined (2.5?10-2, 5?10-2 and 10-1 mg?ml-1) produced relaxation of isolated tracheal smooth muscle. In group Ⅱ , Ⅲ , Ⅳand Ⅴ pretreatment of tracheal strips with indothelin, L-NAME, methylene blue or verapamil did not significantly affect the relaxation of tracheal smooth muscle induced by propofol as compared with group Ⅰ. Pretreatment with glibenclamide significantly depressed the direct relaxant effect of propofol on tracheal smooth muscle ( P

[Objective] To compare and identify the different cultivated varieties of Amormun villosum for providing scientific evidence for the selection, breeding, standardization and industrialization. [Methods] Source appraisal, character identification and scanning electron microscope technique were applied to observe and compare the appearance of the original plant, the properties of the medicinal material and the outside characteristics of pollen of Amomum villosum in Yangchun, Guangdong province. [Results] The two cultivated varieties of Amomum villosum in this area, long-fruit and round-fruit types, are quite different in the appearance and the characteristics of pollen. [Conclusion] It is suggested that long-fruit Amomum villosum and round-fruit Amomum villosum should be the selected varieties for breeding.

[Objective] To observe the influence of different kinds of biological pesticide on the fruiting rate and yield of Amomum villosum Lour. (AVL) . [Methods] Medicinal plant field experiment method was used to observe the influence of biological pesticide A (highly effective immuno-biologic bactericide, 75.76mg?m-2 for one time) and its 1000-fold, 800-fold and 500-fold diluent on the fruiting rate and yield of AVL. Meanwhile, the influence of biological pesticide B (edible oligosaccharide, 30.30mg?m-2 for one time) and biological pesticide C (deguelin emulsion, 1.89mg?2m-2 for one time) was also observed.

Objective To detect the mutations in connexin genes in a family with hidrotic ectodermal dysplasia(HED)complicated by pseudo-ainhum.Methods Peripheral blood samples were collected from a 20-year-old patient with HED complicated by pseudo-ainhum,and from his unaffected sister.Total DNA was extracted from these samples,and PCR was performed to amplify the partial coding region of GJB2,GJB5 and GJB6 genes.Subsequently.PCR products were bidirectionally sequenced in both subjects.Results No mutation was detected in GJB5 or GJB6 gene in either subjects.Two mutations (V27I and V37I)were detected in the GJB2 gene in the patient but not in his sister.Conclusion The mutation in the GJB6 gene may be absent in patients with HED;there might be other genes involved in the pathogenesis.

Objective To assess the clinical characteristics of primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL) and its treatment and prognosis. Methods Twenty patients diagnosed with PGI-DLBCL were admitted to hospital between 2003 and 2007. The clinical characteristics and tumor molecular model of PGI-DLBCL as well as therapeutic methods were retrospectively studied. The factors that related to survival and prognosis were statistically analysed.Results The overall survival (OS) time of the patients were from 42 months to 52 months,while the progression-free survival (PFS) time were from 37months to 47 months. The International Prognostic Index (IPI) score (0～2 or ＞2) played a reminding role in prognosis of the disease. Tumor molecular model was no effect on prognosis [that was no significant difference between germinal center B-cell-like (GCB) type and non-GCB type]. The efficacy of Rituximab in combination with CHOP chemotherapy (R-CHOP) in treatment of PGI-DLBCL was similar to CHOP chemotherapy alone, whereas surgical intervention might prolong survival period. Conclusions The biological characteristics of PGI-DLBCL is so particular that the most therapeutic method, which need to be further studied, would be different from DLBCL in other position.

BACKGROUND: Essential tremor is a kind of dyskinesia disease with a tendency to heredity. β-adnephrin receptor blocker is mainly used for treatment, but the dosage was great, patients could not persist in treatment. Hydrochloric-acid arotinolol, which characterizes by little side effect, is a β-receptor blocking agent combined with blocking effect of α receptor, and is an ideal drug to treat essential tremor in Japan.OBJECTIVE: To observe the reliability and curative effect of hydrochloric-acid arotinolol on essential tremor among Chinese people.DESIGN: Case analysis.SETTING: Neurological Departments of Beijing Hospital of Ministry of Public Health and General Hospital of Beijing Military Area Command of Chinese PLA.PARTICIPANTS: Totally 30 patients with essential tremor, 19 males and 11 females, aged from 21 to 74 years, with course of 1-40 years, average of (15.8±12.6) years, were selected from Neurological Departments of Beijing Hospital of Ministry of Public Health and General Hospital of Beijing Military Area Command of Chinese PLA from April 1999 to December 2000.METHODS: Tremor degree of upper limb, caput and lower limb, degree of dysfunction of hand, tremor degree of hand during writing and circling, and chief complaint of pain caused by tremor were scored before medication and 2, 4 and 6 weeks after medication. Scores were determined as 1 point, 2 points and 3 points according to mild, moderate and severe degree respectively. Evaluated criteria: ① Obviously effective: Differences were more than 7 points before and after treatment. ② Effective: Differences were 6.5-3 points before and after treatment. ③ A little effective: Differences were 3-1.5 points before and after treatment. ④ No changes: Differences were from 1 to -1 points before and after treatment. ⑤ Worse: Differences were less than -1.5 points before and after treatment. Meanwhile, blood pressure and heart rate of patients and side effect of drug were observed.MAIN OUTCOME MEASURES: ① Results of effective evaluation; ②Blood pressure and heart rate before and after treatment; ③ Adverse events and side effect.RESULTS: Totally 30 patients entered the final analysis. ① Among 30 patients with essential tremor, 6 had obvious effect, 11 had effect, 5 had a little effect, 7 had no effect, and 1 was worse. ② Average of blood pressure before treatment was (138.5±14.6)/(84.2±6.4) mm Hg (1 mm Hg=0.133 kPa), and was (130±10)/(79.7±6.3) mm Hg after 1 course. Average heart rate was (77.5±6.4) times/minute before treatment and (75±6.4) times/minute after treatment. The difference was not significant. ③ Among 30 patients, 4 had side effect at various degrees which was accounted for 13.4%; 1 had distress after medication, 1 had agrypnia, 2 had fullness in head and dizziness, and 1 gave up the treatment because of deteriorated tremor.CONCLUSION: Hydrochloric-acid arotinolol can improve tremor symptom of patients obviously and is an effective drug to treat essential tremor with convenient and safe medication.
