Phototherapy plays a significant role in vitiligo treatment.Narrow-band ultraviolet B(NB-UVB)remains the first-line phototherapy for non-segmental vitiligo in clinical practice.In recent years,visible light has emerged as a novel therapeutic approach for vitiligo.Studies indicate that helium-neon laser demonstrates superior efficacy in segmental vitiligo,blue light is more effective for localized vitiligo,and NB-UVB is better suited for generalized or extensive vitiligo.Different phototherapy modalities exhibit distinct mechanisms of action,involving multiple biological proteins and signaling pathways in melanocyte activation and repigmentation.This review sum-marizes recent advances in phototherapy for vitiligo treatment.

Schizophrenia is a common, severe, and complex psychiatric disorder worldwide. Genetic factors account for around 80% of the etiology of schizophrenia, yet objective diagnostic biomarkers remain lacking. This article reports two cases of female monozygotic twins diagnosed with schizophrenia, exhibiting a balanced translocation between 22q11.2 and 4p15.3. Reviewing the literature, we analyze and discuss the correlation between chromosomal balanced translocation regions and the pathogenesis of mental disorders. This aims to encourage psychiatrists to consider new perspectives on the diagnosis of schizophrenia.

Purpose To identify whether serum-free culture can enrich breast cancer stem cells from MCF-7 human breast cancer cell line. Methods MCF-7 human breast cancer cell line by serum-free culture and serum culture technology were cultured, its cell mor-phology and growth pattern were observed by the inverted microscope. The expression of stem cell surface molecular makers CD24, CD44 was observed by the inverted fluorescence microscope and the flow cytometry, the proportion of different subpopulation cells was detected by the flow cytometry. At the same time, difference of the cell cycle was detected by the flow cytometry. Results The cell line cultured by serum-free culture grew in the form of suspended microspheres of different sizes in the medium, but the cell line cul-tured by serum culture grew in the form of monolayer adherent growth. There was no obvious difference in the expression of stem cell surface molecular makers CD44 between the suspended microsphere cells and the adherent cells, but the expression of CD24 in the sus-pended microsphere cells decreased compared to the adherent cells. The proportion of CD44 + /CD24 -/low phenotype cells in the suspen-ded microsphere cells and the adherent cells was (86. 93 ± 0. 53)% and (19. 98 ± 0. 62)%, respectively (P<0. 05), the proportion of CD44 + /CD24 + phenotype cells was (12. 68 ± 0. 59)% and (79. 90 ± 0. 57)%, respectively (P<0. 05). The proportion of mitotic cells in the suspended microsphere cells and the adherent cells was ( 18. 85 ± 2. 26 )% and ( 43. 91 ± 1. 81 )%, respectively ( P<0. 05), the proportion of quiescent cells was (64. 92 ± 2. 07)% and (39. 82 ± 1. 77)%, respectively (P<0. 05). Conclusion CD44 + /CD24 -/low breast cancer stem cells can be effectively enriched by the serum-free culture technology.

Objective To investigate the status and needs of professional training in the rehabilitation institutes associated to Shanghai Disabled Persons' Federation. Methods All the rehabilitation institutes associated to Shanghai Disabled Persons' Federation were surveyed with their theme, frequency and targeted participants of training in 2010. The intention of training of rehabilitation personnel were investigated and ranged as importance and urgency. Results There were some trainings in all the rehabilitation institutes, which varied with the property and level of the institutions. The theme of training did not meet the intention of the personnel. Conclusion A preliminary training system for the rehabilitation personnel has been established in Shanghai Disabled Persons' Federation system. It is needed to improve the needs assessment,curriculum, and teaching.

Objective To evaluate the treatment effects of double parabolic lingual springs appliance and straight wire appliance therapy in skeletal class Ⅲ malocclusion. Methods 12 cases with skeletal class Ⅲ malocclusion were treated by double parabolic lingual springs appliance and straight wire appliance, cephalometric tracing measurement were taken in analysis,compared between pretreatment and posttreatment in each case. Results The comparison of before and after orthodontic treatment showed angle SNA increased by 2.80°, angle SNB decreased 1.39°ANB decreased by 4.88°. Conclusion The above metioned technique could be a reliable way to treat mild and moderate skeletal class Ⅲ malocclusion.

ObjectiveTo analyze application of screening and assessment scales for senile dementia in China.MethodsVarieties of screening and assessment scales were found in the studies on screening and assessment of senile dementia in China, as well as their common features and epidemiological results. A combination of qualitative and quantitative methods was used in the analysis.ResultsMini Mental State Examination (MMSE) is preferred tool in screening and Activity of Daily Living Scale (ADL) is the secondary.ConclusionThe future research direction should include: studying the appropriate boundary value in MMSE for China; optimizing the combination of screening scale and developing more appropriate screening tool.
