Tourette syndrome is a childhood-onset disorder characterized by a combination of motor and vocal tics, often associated with psychiatric comorbidities including attention deficit and hyperactivity disorder and obsessive-compulsive disorder. Despite an onset early in life, half of patients may present symptoms in adulthood, with variable degrees of severity. In select cases, the syndrome may lead to significant physical and social impairment, and a worrisome risk for self injury. Evolving research has provided evidence supporting the idea that the pathophysiology of Tourette syndrome is directly related to a disrupted circuit involving the cortex and subcortical structures, including the basal ganglia, nucleus accumbens, and the amygdala. There has also been a notion that a dysfunctional group of neurons in the putamen contributes to an abnormal facilitation of competing motor responses in basal ganglia structures ultimately underpinning the generation of tics. Surgical therapies for Tourette syndrome have been reserved for a small group of patients not responding to behavioral and pharmacological therapies, and these therapies have been directed at modulating the underlying pathophysiology. Lesion therapy as well as deep brain stimulation has been observed to suppress tics in at least some of these cases. In this article, we will review the clinical aspects of Tourette syndrome, as well as the evolution of surgical approaches and we will discuss the evidence and clinical responses to deep brain stimulation in various brain targets. We will also discuss ongoing research and future directions as well as approaches for open, scheduled and closed loop feedback-driven electrical stimulation for the treatment of Tourette syndrome.

Objective: To analyze the characteristics of super-antigen (SAg) of group A Streptococcus pyogenes (GAS), isolated from patients with scarlet fever or pharyngeal infections in Beijing between 2015-2017. Methods: Throat swab specimens from patients with scarlet fever or pharyngeal infections were collected and tested for GAS. Eleven currently known SAg genes including SpeA, speC, speG, speH, speI, speJ, speK, speL, speM, smeZ and ssa were tested by real-time PCR while M protein genes (emm genes) were amplified and sequenced by PCR. Results: A total of 377 GAS were isolated from 6 801 throat swab specimens, with the positive rate as 5.5%. There were obvious changes noticed among speC, speG, speH and speK in three years. A total of 45 SAg genes profiles were observed, according to the SAgs inclusion. There were significant differences appeared in the frequencies among two of the highest SAg genes profiles between emm1 and emm12 strains (χ(2)=38.196, P<0.001; χ(2)=72.310, P<0.001). There also appeared significant differences in the frequencies of speA, speH, speI and speJ between emm1 and emm12 strains (χ(2)=146.154, P<0.001; χ(2)=52.31, P<0.001; χ(2)=58.43, P<0.001; χ(2)=144.70, P<0.001). Conclusions: Obvious changes were noticed among SAg genes including speC, speG, speH and speK from patients with scarlet fever or pharyngeal infections in Beijing between 2015-2017. SAg genes including speA, speH, speI and speJ appeared to be associated with the emm 1 and emm 12 strains. More kinds of SAg genes profiles were isolated form GAS but with no significant differences seen in the main SAg genes profiles, during the epidemic period.

3.Interpretation of Chinese expert consensus on prevention and treatment of complications related to digestive tract reconstruction after laparoscopic radical gastrectomy for gastric cancer (2022 edition).
Chinese Journal of Gastrointestinal Surgery 2023;26(2):121-125
Gastric cancer is one of the most common gastrointestinal malignancies in China. D2 radical gastrectomy is the main treatment for advanced gastric cancer patients. With the advancement of laparoscopic technology, laparoscopic radical gastrectomy has been gradually developed in the world, and even popularized in China. There have been a lot of literature reports on the indications, the scope of lymph node dissection and the improvement of techniques of laparoscopic radical gastrectomy for gastric cancer. Relevant guidelines or consensus for radical gastrectomy. The prevention and treatment of complications of gastrointestinal reconstruction for laparoscopic radical gastric cancer surgery is a major concern for gastrointestinal surgeons. Once complications occur in digestive tract reconstruction, it would increase the hospitalization cost, prolong the hospitalization stay of patients, delay follow-up chemotherapy, and even lead to postoperative death or other serious consequences. Therefore, it is of positive and far-reaching clinical significance to pay attention to the techniques of gastrointestinal reconstruction after laparoscopic radical gastric cancer surgery, to reduce the occurrence of gastrointestinal reconstruction complications, and to detect and reasonably manage related complications in a timely manner. The Chinese expert consensus on prevention and treatment of complications related to digestive tract reconstruction after laparoscopic radical gastrectomy for gastric cancer (2022 edition) has significance value for reducing the occurrence of gastrointestinal reconstruction complications. This manuscript mainly serves as the interpretation and supplement of this Consensus.

There is no national referral criteria for burns in China till now, which brings inconvenience and confusion. Based on the oversea experiences and the actual situation in China, many famous experts on burns discussed and developed this Chinese burn referral criteria (2018 version). We hope these referral criteria will be helpful in clinical practice in burn field and can be improved continuously during application.

Influenza can be prevented through annual appropriate vaccination against the virus concerned. In China, influenza vaccine is categorized as "Class Ⅱ" infectious diseases which the cost is paid out of the user's pockets. The annual coverage of influenza vaccination had been 2%-3%. The main reasons for the low coverage would include the following factors: lacking awareness on both the disease and vaccine, poor accessibility of vaccination service, and the cost of vaccination. To reduce the health and economic burden associated with influenza, comprehensive policies should be improved, targeting the coverage of seasonal influenza vaccination. These items would include: ① Different financing reimbursement schemes and mechanisms to improve the aspiration on vaccination and on the vaccine coverage in high-risk groups, as young children, elderly, people with underlying medical conditions; ② to ameliorate equality of vaccination services; ③ to improve knowledge of the health care workers (HCWs) and the public on influenza and related vaccines; ④ to improve clinical and preventive medical practice and vaccination among HCWs through revising clinical guidelines, pathway and consensus of experts; ⑤ to provide more convenient, accessible and normative vaccination service system; ⑥ to strengthen research and development as well as marketing on novel influenza vaccines; ⑦ to revise items regarding the contraindication for influenza vaccine on pregnancy women, stated in the Chinese Pharmacopoeia.

Seasonal influenza vaccination is the most effective way to prevent influenza virus infection and its complications. Currently, China has licensed trivalent (IIV3) and quadrivalent inactivated influenza vaccine (IIV4), including split-virus influenza vaccine and subunit vaccine. In most parts of China, influenza vaccine is a category Ⅱ vaccine, which means influenza vaccination is voluntary, and recipients need to pay for it. To strengthen the technical guidance for prevention and control of influenza and the operational research on influenza vaccination in China, the National Immunization Advisory Committee (NIAC), Influenza Vaccine Technical Working Group (TWG), updated the 2014 technical guidelines and compiled the "Technical guidelines for seasonal influenza vaccination in China (2018-2019)" , based on most recent existing scientific evidences. The main updates include: epidemiology and disease burden of influenza, types of influenza vaccines, northern hemisphere influenza vaccination composition for the 2018-2019 season, and, IIV3 and IIV4 vaccines'major immune responses, durability of immunity, immunogenicity, vaccine efficacy, effectiveness, safety, cost-effectiveness and cost-benefit. The recommendations include: Points of Vaccination clinics (PoVs) should provide influenza vaccination to all persons aged 6 months and above who are willing to be vaccinated and do not have contraindications. No preferential recommendation is made for any influenza vaccine product for persons who can accept ≥1 licensed, recommended, and appropriate products. To decrease the risk of severe infections and complications due to influenza virus infection among high risk groups, the recommendations prioritize seasonal influenza vaccination for children aged 6-60 months, adults ≥60 years of age, persons with specific chronic diseases, healthcare workers, the family members and caregivers of infants <6 months of age, and pregnant women or women who plan to pregnant during the influenza season. Children aged 6 months to 8 years old require 2 doses of influenza vaccine administered a minimum of 4 weeks apart during their first season of vaccination for optimal protection. If they were vaccinated in previous influenza season, 1 dose is recommended. People ≥ 9 years old require 1 dose of influenza vaccine. It is recommended that people receive their influenza vaccination by the end of October. Influenza vaccination should be offered as soon as the vaccination is available. Influenza vaccination should continue to be available for those unable to be vaccinated before the end of October during the whole season. Influenza vaccine is also recommended for use in pregnant women during any trimester. These guidelines are intended for CDC members who are working on influenza control and prevention, PoVs members, healthcare workers from the departments of pediatrics, internal medicine, and infectious diseases, and members of maternity and child care institutions at all levels.

The prevalence of child and adolescent growth and mental-behavior related diseases are increasing, and the pathogenesis are complex. Twins are excellent natural resources for complex chronic diseases research as they share the maternal intrauterine environment, born at the same time and share the same family environment in early years, which could benefit the adjust ment of confounding factors, such as age, genetic factors and early family environmental factors. Birth cohort with twin families involved could be more effective in exploring the genetic and environmental factors for complex chronic diseases at the very beginning of life. This paper summarizes the objective, content, progress, strengths and potential problems of Wuhan Twin Birth Cohort, with emphasis on the overall design and progress of the study.
