Objective To approach the status of leprosy disabilities in newly detected cases in recent 10 years in China and provide the scientific basis for formulating the preventive strategies. Methods Based upon the individual records from the National Leprosy Recording and Reporting System in National Center for STD and Leprosy Control, 22 437 leprosy cases detected during 1989－ 1998 in China were analyzed in terms of leprosy disability. Results The proportion of disabilities in newly detected leprosy cases in 1989 in whole country was 46.49％ and decreased to 32.31％ in 1998, and the proportions of cases with grade II disabilities were 25.55％ (1989) and 20.23％ (1998). There were 18 provinces where disability rate was more than 40％ . Out of patients with disabilities, those with grades I and II disabilities and with deformities (loss of eyebrow, facial paralysis or saddle nose) accounted for 37.86％ , 60.64％ and 1.5％ , respectively. There were 25 provinces where grade II disabilities accounted for more than 50％ of all patients with disabilities. The disability rates in patients aged under 15 years, 15－ 65 years and over 65 years were 24％ , 39.85％ and 53.33％ . The patients with a delay in detection of 2 years had a disability rate of 29.85％ , and those with a delay of more than 2 years and 5 years had the rates of 48.82％ and 61.17％ , respectively. The disability rate was 52.9％ in patients with leprosy reactions and 46.1％ in patients with a damage of more than 3 nerves. The grade II disability rate in paucibacillary patients(28.99％ ) was significantly higher than that in multibacillary ones (22.04％ ). Conclusion Disability rate of leprosy in newly detected cases is still high although it has decreased in the recent 10 years. The rate is associated with delay in detection, leprosy reaction and leprosy type. It suggests that early detection of leprosy patients, regular treatment with multidrug therapy, and management of leprosy reactions will be the effective measures to prevent disabilities of leprosy.

Objective To investigate the influence of a catastrophic event to the mental health of servicemen,and to observe the effect of mental intervention and drug treatment for them after experiencing a catastrophic flood attack.Methods 57 servicemen survived a catastrophic flood attack were regarded as the disaster group,and 70 others who were not involved in the flood disaster were regarded as the control group.The service men of the two groups were subjected to investigation with Chinese Military Mental Health Scale(CMMHS),and corresponding mental intervention or medication was given to those who had experienced mental disorders.Results The disaster resulted in different degrees of somatic trauma and various mental disorders including instability of emotion,mental depression,grievance,nervous tension,sensation of fear,sleep disorder and apprehensions.The influential factor scores of CMMHS,including compulsive neurosis,anxiety,depression,fear,psychosis,somatization,interpersonal sensitiveness,and total score were much higher in disaster group than that in control group,and that of norm of Chinese servicemen,while the neurasthenia factor score in disaster group showed no significant difference with that in control group and that of normal Chinese servicemen.The main influential factors to changes in mental health of the servicemen were witness of someone washed away by the flood,and participation in identifying corpses.Conclusion The mental health of servicemen who experienced a catastrophic flood disaster was harmed in various degrees,and medication or mental intervention appeared to be of value.

Objective To explore the efficacy of selective posterior rhizotomy (SPR)and post-operative rehabilitation training in treating cerebral palsy. Methods The 100 patients with cerebral palsy were randomly divided into two groups. In group A, the patients were treated by SPR, and in group B, the patients received rehabilitation training after SPR for 12 months. One year later the curative efficacy of all patients was evaluated and compared between the two groups.Results The effective rate was 52% and 76% in groups A and B respectively. Conclusion It is very important that the patients receive systematic rehabilitation training after SPR so as to gain a most satisfied functional recovery.

Objective: To construct a recombinant expression vector containing the VP1 whole gene of human parvovirus(HPV) B19-XA strain by DNA recombinant technology and to induce the expression of the VP1 fusion protein in E.coli.Methods: The gene of interest was amplified by PCR from the viral DNA genome extracted from the patient infected with B19 virus,and inserted into the pET28(a) expression vector.The positive recombinants pET28(a)-VP1 were transformed into E.coli BL21(DE3),and then the VP1 proteins were expressed after induced by IPTG and analyzed by SDS-PAGE and immunoblotting.In addition,rabbits were immunized with the recombinant VP1 fusion proteins as antibodies,and their valence was detected by ELISA.Results: The positive bacteria strains containing the recombinant expressive vector pET28(a)-VP1 were constructed successfully,and IPTG induced a high expression of the VP1 fusion proteins.The valence of multiclone antibodies of anti-VP1 proteins was 1∶12 800.Conclusion: The VP1 fusion proteins of the HPV B19-XA strain can be expressed efficiently in E.coli,and these proteins possess satisfactory immunogenicity and play an important role in the preparation of diagnostic reagents and the development of vaccines.
