Since the release of On the Promotion of Hierarchical Diagnosis and Treatment System Construction Guidance in 2015,the relevant supporting policies have been introduced.That whether the classification system can continue to implement effectively,still needs the adjustment and protection of legal level.Therefore,in view of the current problems in the construction of the classification and treatment system,the paper conducts an in-depth investigation and analysis,and puts forward the ideas and suggestions for legislation to promote the construction of the classification and treatment system.

Sjögren's syndrome(SS)is a chronic autoimmune disease that affects exocrine glands, especially salivary and lacrimal glands. The main clinical manifestations are dry mouth and dry eyes, but also multi-organ and multi-system can be involved. Cold agglutinin disease(CAD)is an autoimmune disease characterized by red blood cell agglutination in the blood vessels of extremities caused by cold agglutinin at low temperature, resulting in skin microcirculation disturbance, or hemolytic anemia. Cold agglutinin disease is divided into two categories, primary cold agglutinin disease and secondary cold agglutinin disease. Primary cold agglutinin disease is characterized with cold agglutinin titer of 1 ∶4 000 or more and positive Coomb's test. However, the Coomb's test is not necessarily positive and the cold agglutinin titer is between 1 ∶32 and 1 ∶4 000 in secondary cold agglutinin disease. Here, we reported an elderly patient admitted to hospital due to fever. He was diagnosed with respiratory infection, but he showed incompletely response to the anti-infection treatment. Further laboratory tests showed the patient with positive ANA and anti-SSA antibodies. Additionally, the patient complained that he had dry mouth and dry eyes for 1 year. Schirmer test and salivate gland imaging finally confirmed the diagnosis Sjogren's syndrome. During the hospital stay, the blood clots were found in the anticoagulant tubes. Hemolytic anemia was considered as the patient had anemia with elevated reticulocytes and indirect bilirubin. In addition, further examination showed positive cold agglutination test with a titer of 1 ∶1 024, and cold agglutinin disease was an important type of cold-resistant autoimmune hemolytic anemia. Furthermore, the patient developed cyanosis after ice incubating at the tip of the nose. Hence, the patient was diagnosed as CAD and he was successfully treated with glucocorticoids instead of anti-infection treatments. Hence, the patient was diagnosed with SS combined with secondary CAD. SS combined CAD are rarely reported, and they are both autoimmune diseases. The abnormal function of B lymphocytes and the production of autoantibodies might be the common pathogenesis of them. Cold agglutinin disease can lead to severe hemolytic anemia, even life-threatening. In clinical practice, timely recognizing and dealing with CAD might promote the prognosis of the patient.

L_9(3~4) orthogonal experiment design was used to optimize the preparation of the patches,and investigate its affecting factors and skin irritation. Eugenol was taken as the index component to study the release behavior in vitro and percutaneous penetration of Cangai oil transfersomes patches by HPLC.The results showed that the optimal prescription for preparing Cangai oil transfersomes patches were Eudragit E100 0.6 g, succinic acid 0.08 g,triethyl citrate 0.25 g,glycerol 0.2 g.Patches prepared by the preferred preparation had a flat appearance without obvious bubbles.The initial adhesion was 18.33±2.52, the stickiness was(30.01±2.45) min,and the peel strength was(5.62±0.95) kN·m~(-1).The results of affecting factors experiment showed the order of factors affecting its adhesion was humidity>temperature>lighting,and the skin irritation test results showed no significant skin irritation after 24 h of single administration. The results of drug release behavior in vitro showed that the release and the percutaneous penetration of both Cangai oil patches and Cangai oil transfersomes patches conformed to the Higuchi equation.The release amount of eugenol were 80.66% and 82.25% at 72 h, with no significant difference. The cumulative permeation area of eugenol per unit area reached(0.195 6±0.065 9),(0.131 0±0.045 5) mg·cm~(-2) at 72 h, with significant differences(P<0.05).The experiment results proved that the preparation process of Cangai oil transfersomes patches was stable,and the prepared patches had a good adhesion. At the same time,the preparation of transfersomes patches could alleviate and control the release of the drug to a certain extent, and provide a certain experimental basis for clinical pediatric drug safety.
