Tic disorder (TD) is a common neuro-developmental disorders in children during school age. The cause is complex and it can be induced or aggravated by varies of factors such as genetics, exogenous pathogens, and emotions. TD affects children's self-cognition, academic level, and social function, and causes parents to have unhealthy psychological states such as anxiety and depression, and affects family harmony. Therefore, clinical attention should not only be paid to the treatment of this disease, but also to prevention and nursing care. Incubative evil theory is one of the important theories of Traditional Chinese Medicine. This theory can help to treat and prevent diseases. Incubative evil is characterized by no symptoms with spontaneous attack by latent pathogen, but symptoms appearance induced by the pathogen. The pathological process of TD is similar to incubative evil characteristics. This paper discusses the prevention and nursing care of children's tic disorder based on the theory of incubative evil.

Objective:To analyze the medication law of external application of TCM in the treatment of psoriasis vulgaris (PV) by using data mining method.Methods:Clinical controlled trial literature about external application of TCM in the treatment of PV was retrieved from CNKI, VIP, WanFang, SinoMed, PubMed and Cochrane Library from the establishment of the databases to May 23, 2022. Prescriptions were extracted after screening. TCM inheritance computing platform V3.0 was used to analyze the property, taste, meridian, efficacy, use frequency, common medicinal pairs and the core combinations.Results:A total 186 prescriptions were included, involving 190 kinds of Chinese materia medica. The medicines were mostly bitter and cold in property and taste, mainly belonging to the liver and heart meridians. Heat-clearing drugs were mainly used, followed by blood circulation-activating and stasis-eliminating medicines, and tonic medicines. The ten most frequently used medicines were Sophorae Flavescentis Radix, Dictamni Cortex, Phellodendri Chinensis Cortex, Kochiae Fructus, Angelicae Sinensis Radix, Salviea Miltiorrhizae Radix et Rhizoma, Poria, Rehmannine Radix, and Arnebiae Radix; the 3 commonly used medicinal pairs were Sophorae Flavescentis Radix- Dictamni Cortex, Sophorae Flavescentis Radix- Cnidii Fructus, and Sophorae Flavescentis Radix- Kochiae Fructus; 4 combinations were obtained through evolution. Conclusions:External application of TCM for the treatment of PV is around the core pathogenesis of "heat toxin", mainly treating from the blood, including cooling blood and detoxifcation, activating blood circulation and removing stasis, nourishing the blood and moistening dryness. Clearing heat and drying dampness, dispelling wind and relieving itching are also valued. The treating thoughts can provide some references for clinical treatment.

The spread of COVID-19 has greatly threatened human health and economic growth. Angiotensin-converting enzyme 2 (ACE2) is a receptor for severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). By attaching to ACE2, SARS-COV-2 reduces its expression and induces lung injury. Vitamin D can inhibit the progression of COVID-19 by inhibiting the activity of ROCK pathway, up-regulating ACE2 expression and bio-availability, and slowing down the adverse reactions caused by Ang II accumulation. This study explored a novel mechanism, i.e., vitamin D protects against COVID-19-induced injury by upregulating ACE2 expression. It provides theoretical guidance for the role of Vitamin D in the prevention and treatment of COVID-19.

ObjectiveTo compare the efficacy and safety of acupuncture combined with auricular acupoints patches and nicotine transdermal patch in treating moderate to severe nicotine dependence. MethodsIn a rando-mized controlled trial， 64 quit smoking voluntary subjects with moderate to severe nicotine dependence were randomly divided at a ratio of 1∶1 into a treatment group and a control group， with 32 cases in each group. The treatment group was given acupuncture combined with auricular acupoints patches， twice weekly， four weeks as a course for two courses. The control group was given nicotine transdermal patch， one patch per day for 24 hours， 8 weeks. The cure rate was assessed after treatment and at follow-up （the 16th week after treatment）.The daily smoking volume， exhaled carbon monoxide （CO） value， Nicotine Dependence Scale （FTND）， Minnesota Nicotine Withdrawal Symptoms Scale （MNWS）， and Pittsburgh Sleepiness Index Inventory （PSQI） were evaluated before and after treatment and at follow-up， and adverse effects were recorded. ResultsIn terms of the cure rate， there were both six cured cases （20%） after treatment and at follow-up in the treatment group， while in the control group， seven （23.3%） and five （16.7%） patients were cured after treatment and at follow-up， respectively， with no statistically significant differences between the two groups both after treatment and at follow-up （P＞0.05）. The daily smoking volume and exhaled CO value significantly decreased after treatment and at follow-up in both groups （P＜0.05）， but were not significantly different between the groups after treatment and at follow-up （P＞0.05）. After treatment and at follow-up， FTND， MNWS， and PSQI scores were significantly reduced in both groups compared with those before treatment （P＜0.05）. There was no statistically significant difference in the FTND scale scores between the two groups after treatment and at follow-up （P＞0.05）， while the MNWS and PSQI scale scores were lower in the treatment group than in the control group （P＜0.05）. ConclusionAcupuncture combined with auricular acupoint patches for moderate to severe nicotine dependence has comparable effect with the first-line drug nicotine patch in terms of increasing the cure rate and decreasing the degree of nicotine dependence， and is superior to nicotine patch in terms of relieving withdrawal symptoms and improving sleep， with stable long-term effect.
