OBJECTIVE:To explore the effects of levothyroxine on the follicular helper T lymphocyte level of patients with Hashimoto's thyroiditis. METHODS:51 patients with Hashimoto's thyroiditis were selected as levothyroxine group,and another 30 healthy people were control group. Levothyroxine group was orally given 25-50 ug Levothyroxine sodium tablet,once a day,the dose was adjusted based on thyroid function,and the dose maintained when thyroid function turned normal,for continuous 90 d. Free triiodothyronine(FT3),free thyroxine(FT4),thyroid stimulating hormone(TSH)and the percentage of Th17 cells account-ed for peripheral blood CD4+ T cells(Th17/CD4+)in levothyroxine group before and after treatment were observed and compared with control group,the correlation of Th17/CD4+ and thyroid function. RESULTS:After treatment,Th17/CD4+ level in levothyrox-ine group were significantly lower than before and higher than control group,the differences were statistically significant(P<0.05). TSH in levothyroxine group were significantly lower than before,FT3 and FT4 were significantly higher than before,the differenc-es were statistically significant(P<0.05);compared with control group,the differences were not statistically significant(P>0.05). Th17/CD4+ showed positive correlation with thyroid function in levothyroxine group. CONCLUSIONS:Levothyroxine can signifi-cantly reduce the Th17/CD4+ and TSH,increase FT3 and FT4,and Th17/CD4+ is involved in the occurrence and progression of Hashimoto's thyroiditis.

Objective To explore the impact of the systematic social skills training on recovery of chronic schizophrenia patients with negative symptom and social skills defects.Methods A total of 82 cases of long -term hospitalized patients with chronic schizophrenia were randomly divided into intervention group and control group by digital table,41 cases in each group.The two groups received psychiatric routine therapy and nursing,and general entertainment therapy,and systemic social skills training was conducted in the intervention group for 12 weeks.PANSS and SSC were respectively used to evaluate the two groups before and after the intervention.Results After 12 weeks of systematic social skills training,the total score of SSC[(24.5 ±4.5)points]in the intervention group was apparently lower than that in the control group[(29.2 ±5.2)points],and the difference was statistically significant(t =3.212, P <0.01).Compared with the control group[(20.5 ±4.3)points,(27.2 ±4.2)points,(59.1 ±9.5)points],in the intervention group the score of negative symptom mental pathology and total score of PANSS were (14.9 ± 3.7)points,(24.5 ±3.5)points,(52.8 ±7.1)points.The differences of total score between the two groups were sta-tistically significant(t =5.199,3.317,3.239,all P <0.01),while the positive symptoms score was not statistically significant(P >0.05).Compared with before intervention,in the negative symptom table,the differences of total score N2,N3,N4,N6 had statistically significant differences(t =4.533,5.413,4.501,4.668,all P <0.01).Conclusion The systematic social skills training can greatly promote chronic schizophrenia patients with negative symptom and social skills defects,improve their social skills and life qualities.

Objective To explore the impact of the systematic social skills training on recovery of in -patients with chronic schizophrenia.Methods A total of 78 cases of long -term hospitalized patients with chronic schizophrenia were randomly divided into intervention group and control group on the basis of random number table. The two groups received psychiatric routine therapy and nursing,and general entertainment therapy,and the patients in the intervention group received group social skills training for 12 weeks.IPROS and SSSI were respectively used to evaluate two groups before the intervention,trained for 12 weeks.Results After 12 weeks'of systematic social skills training,social function defect levels SSSI score in the intervention group was apparently higher than that in the control group,and the difference was significant (χ2 =8.952,P <0.05 ).Compared with the control group (19.4 ± 4.5)points,(16.5 ±4.7 )points,(13.6 ±4.1 )points,(5.5 ±3.1 )points,(18.2 ±4.2 )points,(73.2 ± 16.3)points,in the intervention group public medical situation (10.3 ±5.5)points,life ability(12.1 ±5.7)points, social ability(6.2 ±3.5)points,antiseptic ability (3.3 ±3.3)points,concern and interest (9.6 ±4.5)points as well as the total score of IPROS (44.6 ±20.4),the differences were significant(t =7.760,6,188,8.165,2.568, 6.632,8.259,all P <0.05).Compared with before intervention,each factor in IPROS and the total score in the inter-vention group had statistically significant differences (t =8.890,7.923,8.321,3.195,8.21,9.852,all P <0.01). Conclusion The systematic social skills training can greatly promote the recovery of in -patients with chronic schiz-ophrenia,improve their social skills and life qualities.Compared with control group,the social function of patients in the intervention group has recovered positively.

BACKGROUND: Hypertrophic scar results from imbalance between local collagen synthesis and degradation and abnormal aggregation of collagen after burn and trauma.OBJECTIVE: To observe the effects of collagenase on collagen degradation in nude mice with graft of hypertrophic scar and its therapeutic effects on hyertrophic scar.DESIGN: Controlled experiment was designed.SETTING: Department of Rehabilitation and Physical Therapy,Southwest Hospital, Third Military Medical University of Chinese PLA MATERIALS: The experiment was performed in Experimental Center of the Third Military Medical University of Chinese PLA from July 1995 to April 1997, in which, 10 specimens of hypertrophic scar were employed, collected from the removed hypertrophic scars in Department of Plastic Surgery.All of patients were in the known before the operation. Experimental animals were 15 BACB/C nude mice, of which, 8 mice were male and 7 mice female.Totally 15 mice were grafted with hypertrophic scar tissue, 10 mice of which were survived after once graft; with second graft in the rest mice, 2 mice were survived and 3 mice were dead. The survival nude mice were randomized into experimental group and the control, 6 mice in each one.METHODS: The removed hypertrophic scars in plastic operation were grafted in the wound on the dorsum of nude mice to establish graft model of hypertrophic scar. In experimental group, 1% collagenase was injected locally in scar tissue; in the control group, collagease solvent was injected locally, once a week, for 4 weeks totally. After treatment, the materials were collected for macrogcopic observation and observation and analysis with optic and electronic microscopes.scar tissue before and after treatment.RESULTS: Twelve nude mice were survived after scar graft and all of them entered result analysis, 6 mice of which were in experimental group was smaller in size, thinner in thickness and softer in quality compared staining, Van Gieson's collagenous fiber staining and compound staining on slices, it was displayed that in experimental group, dermal layer became thin, collagenous fiber was unclear in structure and disperse in arrangement, but in the control, the dermal layer of scar tissue was hypertrophic microscopic observation, in experimental group, collagenous fibers were destroyed and unclear in structure, but in the control, collagenous fibers were disturbed in arrangement with distinct strips and clear structure.CONCLUSION: Collagenase degrades collagen of hypertrophic scar,lessens and softens scar, suggesting that local injection of collagease is probably a good therapy for hypertrophic scar.
