ObjectiveTo explore the efficacy and safety of risperidone and haloperidol in treating Tic disorder.Methods78 patients with Tic disorder were randomly divided into the risperidone group and haloperidol group with 39 cases in each group and treated with risperidone and haloperidol respectively for 8 weeks. All patients of two groups were assessed with the Clinical Global Impression Scale (CGI) and Treatment Emergent Symptom Scale (TESS) before treatment and at the end of the 2nd, 4th and 8th week after treatment. Dosages of patients of two groups were recorded.ResultsAfter 8 weeks treatment, the average maximum dosage of risperidone was (1.4±0.34)mg, and that of haloperidol was (7.3±0.52)mg. The total effective rate of risperidone group was 82% and that of haloperidol group was 82.3 %. There was no significant difference between two groups ( P>0.05). The incidence of adverse reactions in risperidone group was 28.2%, and that in haloperidol group was 76.9%. There was a significant difference between two groups (P<0.01), especially at the end of 2nd week after treatment.ConclusionRisperidone and haloperidol both are effect on Tic disorder, but safety and compliableness of risperidone are higher.

Objective: To analyze the strengths, weaknesses, opportunities and threats of the construction on intelligent vaccination clinics in Zhejiang Province, so as to provide countermeasures for promoting the construction of intelligent vaccination clinics in Zhejiang Province. Methods: By reviewing the annual reports of Zhejiang immunization planning, survey data from Zhejiang Centers for Disease Control and Prevention and Immunization Intelligent Service System, data of human resources of immunization planning, vaccine procurement, construction progress of intelligent vaccination clinics and vaccination were collected. The relevant literature was searched to gather information on the construction standards and norms of intelligent vaccination clinics. The analysis of the strengths, weaknesses, opportunities and threats (SWOT) of the construction of intelligent vaccination clinics was conducted, and corresponding countermeasures and suggestions were proposed. Results: The National Immunization Program reported vaccine rate in Zhejiang Province is more than 99%, and standardized vaccination clinics have been popularized throughout the province. The vaccination staff are professional, and a province-wide intelligent immunization service information system has been established, providing the resources and conditions for the construction of intelligent vaccination clinics. However, there are problems such as low data quality and matching efficiency in vaccination, insufficient data interoperability and sharing, unbalanced regional capabilities in intelligent transformation, and uneven distribution of talent and resources. It is crucial to seize the opportunities presented by the development of big data and artificial intelligence, rely on the regional development of the Internet and health industry, seize the opportunity of rapid growth in demand for intelligent vaccination services and high public acceptance, accelerate the construction of intelligent vaccination clinics, and establish intelligent vaccination service standards as soon as possible. Conclusion We should seize the opportunities presented by the digital reform and development, fully utilize the existing vaccination resources and strengths, address the shortcomings, and accelerate the construction of intelligent vaccination clinics in Zhejiang Province.

Hepatocellular carcinoma (HCC) is a common malignant tumor with high incidence and mortality rates in China. Most patients are diagnosed at an advanced stage when seeking medical treatment. Interventional therapy is the main local treatment for HCC. As a new interventional material, CalliSpheres drug-eluting microspheres have more advantages than iodipin in traditional transcatheter chemoembolization, and hepatic artery infusion chemotherapy has higher rates of remission and translation. A series of targeted drugs, such as lenvatinib, donafinib, and apatinib have been approved for application in the treatment of advanced HCC. Immune checkpoint inhibitors have made breakthroughs in the treatment of advanced HCC. Various new drugs are emerging, with clinical studies on various combinations of different therapeutic drugs being gaining new findings. This article aims to discuss the recent applications and clinical research progress of interventional therapy, targeted therapy and immunotherapy in the treatment of advanced HCC so as to provide a reference for the decision-making of HCC.

Background and Objectives: Regenerative endodontic procedures (REPs) are a research hotspot in the endodontic field. One of the biggest problems of REPs is that it is difficult to realize regeneration of pulp-dentin complex and functional reconstruction. The reason is still not clear. We hypothesize that the migration may be different in different dental stem cells. Periodontal ligament stem cells (PDLSCs) may migrate faster than stem cells of apical papilla (SCAPs), differentiating into cementum-like tissue, bone-like tissue and periodontal ligament-like tissue and, finally affecting the outcomes of REPs. Hence, this study aimed to explore the mechanism that regulates the migration of PDLSCs. Methods: and Results: After isolating and culturing PDLSCs and SCAPs from human third molars, we compared the migration of PDLSCs and SCAPs. Then we investigated the role of SDF-1α-CXCR4/CXCR7 axis in PDLSC migration. We further investigated the impact of Porphyromonas gingivalis (P. gingivalis) lipopolysaccharide (LPS) on PDLSC migration and the potential mechanism. PDLSCs showed better migration under both noninflammatory and inflammatory conditions than SCAPs. SDF-1α can promote the migration of PDLSCs by elevating the expression of CXCR4 and CXCR7, increasing the interaction between them, promoting expression of β-arrestin1 and activating the ERK signaling pathway. P. gingivalis LPS can promote the migration of PDLSCs toward SDF-1α through increasing the expression of CXCR4 via the NF-κB signaling pathway, promoting the expression of β-arrestin1, and activating the ERK signaling pathway. Conclusions This study helped elucidate the potential reason for the difficulty in forming pulp-dentin complex.

Diabetes is in the category ofin TCM, which is mainly discussed in light ofdeficiency. The conception vessel is the sea ofmeridians, acting on regulating the accumulation and irrigation ofand blood of twelve meridians and collaterals. The physiological function of the conception vessel is closely related to the pathogenesis of, its running course is highly coincident with the location ofand the symptoms ofare relevant with the indications of the conception vessel. Hence, harmonizingand blood of the conception vessel may be an effective approach to the prevention and treatment of.

Objective: To investigate the incidence of contact dermatitis among workers in cemented carbide production enterprises. Methods: From October 1997 to October 2017, an occupational epidemiological survey was conducted on a large-scale cemented carbide production enterprise, and occupational health examinations were conducted for employees. 152 people were exposed to hard metal dust (hard metal raw material dust and alloy dust) . The employees in the work group were contact groups, and 142 employees in the non-dusting operation of the company were in the control group. A detailed retrospective survey of hard metal production workers with contact dermatitis history in the two groups was conducted to analyze the risk factors of contact dermatitis exposure to hard metal dust. Results: The incidence of allergic diseases in the exposed group was significantly higher than that in the control group. The difference was statistically significant (χ²=23.793, P<0.05) . The incidence of contact dermatitis in the exposed group was significantly higher than that in the control group. The difference was statistically significant (χ²=24.659, P<0.05) ; the changes of contact dermatitis in the contact group were mainly allergic contact dermatitis, and some showed irritative contact dermatitis; the operator had respiratory symptoms (including work-related nasal congestion, cough, wheezing) , difficulty breathing may be the influencing factors of contact dermatitis (RR=2.60, 95%CI: 1.10-6.20, P<0.05) . Conclusion Hard metal alloy enterprises are exposed to hard metal dust. The incidence of contact dermatitis is high in workers, and the occurrence of contact dermatitis may be associated with those with respiratory symptoms.
