The diagnosis and treatment resources for rare diseases in China are highly imbalanced. The basic diagnosis and treatment capabilities are weak, the diagnosis period for patients is long, and the rates of missed diagnosis and misdiagnosis are relatively high. The establishment of a hierarchical diagnosis and treatment system is the inevitable approach to enhancing the diagnosis and treatment standards of rare diseases. Currently, the implementation of the domestic hierarchical diagnosis and treatment system for rare diseases still confronts numerous challenges, such as ambiguous referral standards and processes of primary medical institutions, and ineffective information interaction among institutions at all levels. Thus, it is essential to facilitate high-level information construction for the hierarchical diagnosis and treatment of rare diseases. This paper explores the process of constructing a multidisciplinary joint remote diagnosis and treatment platform and a health management platform through informatization, with the hope of establishing two closed loops of digital diagnosis and treatment services and health follow-up management for patients with rare diseases, as well as achieving timely diagnosis and lifelong health management for patients. It integrates and optimizes auxiliary diagnostic tools, promotes the rapid dissemination of rare disease diagnosis and treatment experiences to the grassroots, enhances the information construction level of the hierarchical diagnosis and treatment system, and endeavors to address the practical predicament of weak diagnosis and treatment capabilities of rare diseases in grassroots medical institutions. Additionally, this paper proposes an essential approach for multi-dimensional independent innovation to guide the popularization of efficient and high-quality rare disease diagnosis and treatment services. By encompassing innovating the rare disease diagnosis and treatment collaboration network and multidisciplinary diagnosis and treatment model, facilitating the application of the latest biomedical and informatics technologies to the grassroots, and constructing a national intelligent data platform for rare disease innovation, a new model for rare disease services with Chinese characteristics will be established. This will significantly enhance the medical treatment level of rare diseases in China and strive for more benefits for patients.

Objective To explore the effect of the expressive psychotherapy on the feeling of inadequacy and loneliness of inpatients with chronic schizophrenia.MethodsTotally 120 chronic schizophrenia inpatients met recruited criteria were randomly divided into study group(n=60) and control group(n=60) according to random number table.57 patients in each group finished all the follow-ups finally.The patients in two groups were received normal medications while the patients in intervention group also attended expressive psychotherapy.All the patients were assessed at baseline,6 weeks and 12 weeks of treatment with the feeling of inadequacy scale (FIS) and the status and trait loneliness scale (STLS).Results(1) The FIS score(F=225.19,P<0.01),STLS total score(F=225.20,P<0.01),STLS status score(F=240.40,P<0.01) and STLS trait score(F=106.75,P<0.01) decreased significantly in both groups after intervention.(2) The FIS score of study group was much lower than those of control group at the at 6-week-follow-up(4.93±20.86,57.89±20.48,t=-2.250,P<0.01) and 12-week-follow-up(38.43±17.50,57.21±22.98,t=-4.900,P<0.01).(3) After 6 weeks treatment and 12 weeks treatment,STLS total score(6 weeks:(54.32±12.30) vs (68.46±15.53),t=-5.425,P<0.01,12 weeks:(44.16±10.81) vs (65.75±16.26),t=-8.386,P<0.01),STLS status score (6 weeks:(25.95±6.41) vs (34.31±7.91),t=-6.239,P<0.01,12 weeks:(19.15±5.49) vs (32.58±8.45),t=-10.103,P<0.01) and STLS trait score (6 weeks:(28.37±6.73) vs (34.15±8.45),t=-4.138,P<0.01,12 weeks:(25.00±6.18) vs (33.15±8.22),t=-6.019,P<0.01) in study group were lower than those in control group,and the difference was statistically significant.ConclusionExpressive psychotherapy can effectively improve the loneliness and inadequacy of patients with chronic schizophrenia.

Objective To assess the value of color Doppler ultrasonogarphy in the diagnosis of subacute thyroiditis (SAT). Methods Sixty-eight patients of SAT and 30 patients with thyroid papillary carcinoma were included, and their imaging features were retrospectively reviewed. Results All the patients with SAT had either focal or diffuse hypoechogenicity of the thyroid lobes with rich blood supplying in the diseased region, among them 52 patients (76.47%, 52/68) had tenderness on palpation. Diffuse and focal lesions were found in 40 (58.82%, 40/68) and 28 patients (41.18%, 28/68). The boundary and shape of focal lesions had no diagnostic characteristics compared with those of thyroid papillary carcinoma. Punctate calcification and resistance index (RI) in the nodule were significant different between the SAT and thyroid papillary carcinoma (P＜0.05). Conclusion Color Doppler ultrasonography can display the features of SAT and is an effective method for the diagnosis of SAT.
