ABSTRACT
OBJECTIVE To prepare Leonurine hydrochloride tablets and evaluate the quality. METHODS The wet granulation technology was adopted ；leonurine hydrochloride was used as the crude drug ，and the types of fillers ，disintegrants，binders and lubricants were screened by single-factor experiments. Combined with orthogonal experiments ，using the cumulative dissolution rate within 15 minutes（using water as dissolution media ）as index ，the proportion of disintegrants ，the mass fraction of binder solution，and the proportion of lubricants were screened and verified. The in vitro dissolution behavior of the prepared Leonurine hydrochloride tablets （dissolution media were hydrochloric acid solution of pH 1.2，acetic acid-sodium acetate solution of pH 4.5， phosphate buffer solution of pH 6.8，water），tablet appearance ，hardness，friability and content uniformity were tested according to the general principles in 2020 edition of Chinese Pharmacopoeia （part Ⅳ）. RESULTS The optimal formulation of Leonurine hydrochloride tablets included leonurine hydrochloride crude drug of 500 mg，dextrin of 9 250 mg，crosslinking polyving y- pyrrolidone of 200 mg，magnesium stearate of 50 mg，1％ hydroxypropyl methyl cellulose solution of 4 mL. The average 15-minute cumulative dissolution rate of the three batches of tablets was 81.25％（RSD＝1.12％，n＝3）. In above 4 dissolution media，the dissolution equilibrium of prepared tablets could be reached within 30 minutes，and the cumulative dissolution rates exceeded 85％. The prepared tablets had uniform beige in color ，smooth surface ，complete edge ，no mottle ，spot，foreign matter ， etc.，hardness of 57.3 N（n＝6），weight loss rate of 0.15％. The content uniformity was in accordance with relevant provisions in 2020 edition of Chinese Pharmacopoeia （part Ⅳ）. CONCLUSIONS Leonurine hydrochloride tablets are successfully prepared ， and the quality comply with relevant regulations.
ABSTRACT
Objective To investigate the first pathogenetie feature and the reason of misdiagnosis about the multiple sclerosis(MS). Methods To review and analyze 62 eases with the first pathogenetic medical record of MS. Results The most frequent clinical manifestation pf the first pathogenetie MS are the limbs paraesthesia(18 eases, 29.0%) ,dyskinesia(16 cases,25.8%) and visual disorder(11 cases, 17.7%), and the other clinical manifestation are the ataxia, epileptic seizure ,dyasarthria, dysuria, itch of skin, mental anomaly, vertigo and so on. The total of misdi-agnosis is 24 cases (38.7 %). Conclusion Except the main clinical manifestation, there are diversity, complexity forfirst pathogenetic MS,what's more the misdiagnosis rate is very high.

ABSTRACT
Objective To study the curative effect of cerebrospinal fluid replacement combining intravenous drips and intrathecal injection of amphotericin B in the treatment of cryptococcal neoformans meningitis(CNM for short).Methods 28 CNM patients were randomly divided into two groups.Group A was the treatment group,and the treatment method was cerebrospinal fluid replacement combining intravenous drips and intrathecal injection of amphotericin B.Group B was the control group,and the treatment method was only intravenous drips and intrathecal injection of arnphotericin B.The period of treatment was 16 weeks.The curative effect was assessed in terms of symptoms,physical features,CSF routine examination,CSF cultivation and smear examination.Results The cura- tive effect of treatment group was better than that of the control group.There were remarkable differences between these two groups(P
