AIM: By introducing the thinking and experience of professor Deng Tietao to treat myasthenia gravis, to improve the therapeutic effect and prognosis.benefiting vital qi had been the main line throughout the whole process of phasized that while we grasp spleen-asthenia, we must give consideration to other organs at the same time, regulate and treat the patient with multistrengthening muscle and increasing strength (radix astragali, radix codonopsis pilosulae, rhizoma atractylodis macrocephalae, rhizoma cimicifugae, pericarpium citri reticulatae, radix fici simplicissimae, etc.), the disease had been treated with different dosage of drugs according to the py for one or two years, even though the symptoms had disappeared completely.RESULTS: Because of grasping the root cause, therapy with multi-means and modified prescription according to the varied symptoms, it had a satisfactory effect. An excellent therapeutic effect had been obtained with the decoction for strengthening muscle and increasing strength, which is created by Deng himself.CONCLUSION: Deng's theory holds that myasthenia gravis is mainly due to spleen-asthenia, and related to other four organs (with a predominance of kidney), and the therapy should be strengthening the spleen-qi, so the prescription was selected for strengthening muscle and increasing strength (which is created by Deng himself), with radix astragali being in a lager quantity. Moreover, he paid more attention to psychological therapy and dietary regulation. The Deng's theory is of considerable clinical significance in guiding treatment of myasthenia gravis.

Objective To investigate the value of detecting hepatitis B virus (HBV) YMDD variants by matrix-assisted laser de-sorption time of flight mass spectrometry (MALDI-TOF MS). Methods The assay is based on polymerase chain reaction (PCR) amplifica-tion and mass measurement of oligonucleotides containing sites of mutation of the YMDD motif. Result The MALDI-TOF MS-based genoty-ping assay was sufficiently sensitive to detect as few as 100 copies of HBV genome per milliliter of serum, and this method had superior spe-cificity for determining mixtures of wild-type and variant viruses. When sera of 40 patients were analyzed, the MALDI-TOF MS-based assay correctly identified known viral variants and additional viral quasi-species not detected by previous methods, as well as their'relative abun-dance. Conclusion The sensitivity, specificity and amenability to high-throughput analysis make MALDI-TOF MS-based assay suitable for mass screening of HBV infected patients who are receiving lamivudine.

Objective:The purpose of our experiment was to use CT to observe the opening of BBB at the early stage of severely scalded rabbits. Methods:Healthy male New Zealand white rabbits were used to establish 30% and 50% TBSA Ⅲ?scalded model. Using high resolution spiral CT (SCT), the brain parenchyma were observed when plain CT scan and contrast-enhanced CT were performed. Results:CT image changes were found in 4 cases at 6 hour after scald of 30% TBSA Ⅲ?scalded rabbits, while CT image changes were found in all cases at 6 hour after scald of 50% TBSA Ⅲ?scalded rabbits. Conclusion:The larger TBSA is Ⅲ?scalded, the earlier BBB is opening . BBB of 50% TBSA Ⅲ?scalded rabbits are wider than that of 30% TBSA Ⅲ?scalded rabbits
