Influenza is an acute respiratory infectious disease caused by the influenza virus, which seriously affects human health. The influenza virus has frequent antigenic drifts that can facilitate escape from pre-existing population immunity and lead to the rapid spread and annual seasonal epidemics. Influenza outbreaks occur in crowded settings, such as schools, kindergartens, and nursing homes. Seasonal influenza epidemics can cause 3-5 million severe cases and 290 000-650 000 respiratory disease-related deaths worldwide every year. Pregnant women, infants, adults 60 years and older, and individuals with comorbidities or underlying medical conditions are at the highest risk of severe illness and death from influenza. Given the ongoing COVID-19 pandemic, some provinces in southern China had a summer peak of influenza. SARS-CoV-2 may co-circulate with influenza and other respiratory viruses in the upcoming winter-spring influenza season. Annual influenza vaccination is an effective way to prevent influenza, reduce influenza-related severe illness and death, and reduce the harm caused by influenza-related diseases and the use of medical resources. The currently approved influenza vaccines in China include trivalent inactivated influenza vaccine (IIV3), quadrivalent inactivated influenza vaccine (IIV4), and trivalent live attenuated influenza vaccine (LAIV3). IIV3 is produced as a split virus vaccine and subunit vaccine; IIV4 is produced as a split virus vaccine; and LAIV3 is a live, attenuated virus vaccine. Except for some jurisdictions in China, the influenza vaccine is a non-immunization program vaccine-voluntarily and self-paid. China CDC has issued 'Technical Guidelines for Seasonal Influenza Vaccination in China' every year from 2018 to 2021. Over the past year, new research evidence has been published at home and abroad. To better guide the prevention and control of influenza and vaccination in China, the National Immunization Advisory Committee (NIAC) Influenza Vaccination Technical Working Group updated and revised the 2021-2022 Technical Guidelines with the latest research progress into the 'Technical Guidelines for Seasonal Influenza Vaccination in China (2022-2023)'. The new version has updated five key areas: (1) new research evidence-especially research conducted in China-has been added, including new estimates of the burden of influenza disease, assessments of influenza vaccine effectiveness and safety, and analyses of the cost-effectiveness of influenza vaccination; (2) policies and measures for influenza prevention and control that were issued by the government over the past year; (3) influenza vaccines approved for marketing in China this year; (4) composition of trivalent and quadrivalent influenza vaccines for the 2022-2023 northern hemisphere influenza season; and (5) recommendations for influenza vaccination during the 2022-2023 influenza season. The 2022-2023 Guidelines recommend that vaccination clinics provide influenza vaccination services to all people aged 6 months and above who are willing to be vaccinated and have no contraindications to the influenza vaccine. For adults ≥ 18 years, co-administration of COVID-19 and inactivated influenza vaccines in separate arms is acceptable regarding immunogenicity and reactogenicity. For people under 18 years old, there should be at least 14 days between influenza vaccination and COVID-19 vaccination. The Guidelines express no preference for influenza vaccine type or manufacturer-any approved, age-appropriate influenza vaccines can be used. To minimize harm from influenza and limit the impact on the effort to prevent and control COVID-19 in China, the Technical Guidelines recommend priority vaccination of the following high-risk groups during the upcoming 2022-2023 influenza season: (1) healthcare workers, including clinical doctors and nurses, public health professionals, and quarantine professionals; (2) volunteers and staff who provide services and support for large events; (3) people living in nursing homes or welfare homes and staff who take care of vulnerable, at-risk individuals; (4) people who work in high population density settings, including teachers and students in kindergartens and primary and secondary schools, and prisoners and prison staff; and (5) people at high risk of influenza, including adults ≥ 60 years of age, children 6-59 months of age, individuals with comorbidities or underlying medical conditions, family members and caregivers of infants under 6 months of age, and pregnant women. Children 6 months to 8 years of age who receive inactivated influenza vaccine for the first time should receive two doses, with an inter-dose interval of 4 or more weeks. Children who previously received the influenza vaccine and anyone 9 years or older need only one dose. LAIV is recommended only for a single dose regardless of the previous influenza vaccination. Vaccination should begin as soon as influenza vaccines become available and preferably should be completed before the onset of the local influenza season. Repeated influenza vaccination during a single influenza season is not recommended. Vaccination clinics should provide immunization services throughout the epidemic season. Pregnant women can receive inactivated influenza vaccine at any stage of pregnancy. These guidelines are intended for use by staff of CDCs, healthcare workers, maternity and child care institutions and immunization clinic staff members who work on influenza control and prevention. The guidelines will be updated periodically as new evidence becomes available.

Epidemic cerebrospinal meningitis (meningococcal meningitis) is an acute respiratory infectious disease with high mortality and serious sequelae. Meningococcal vaccine is an effective measure to prevent and control meningococcal meningitis. At present, group B meningococcal meningitis has become the main prevalent serum group in the world, including China. Meningococcal ACYW and other vaccines are mainly composed of capsular polysaccharides, while the main component of group B meningococcal vaccine is protein, including outer membrane vesicles (OMV) and recombinant protein vaccine. The methods for evaluating the immunogenicity of group B meningococcal vaccine include hSBA and alternative methods such as meningococcal antigen typing system (MATS), flow cytometric meningococcal antigen surface expression assay (MEASURE), genetic meningococcal antigen typing system (gMATS) and bexsero antigen sequence type (BAST). The evaluation of vaccine immunogenicity is the basis of vaccine development and clinical trial research, However, at present, there is no group B meningococcal vaccine in China. Therefore, in this paper, the research progress of immunogenicity evaluation of group B meningococcal vaccine has been reviewed, in order to provide technical guidance for the research and development of group B meningococcal vaccine, immunogenicity evaluation and clinical trial research in China.

Despite impressive survival benefits with immunotherapy in patients with various solid tumors, the full potential of these agents in prostate cancer has yet to be realized. Sipuleucel-T demonstrated a survival benefit in this population, indicating that prostate cancer is an immunoresponsive disease; however, these results have not been matched by other agents. A large trial with ipilimumab in prostate cancer failed to meet its primary objective, and small trials with PD-1/PD-L1 inhibitors did not yield a significant improvement in overall response. However, several late-stage clinical trials are underway with other vaccines in prostate cancer. Reports of clinical benefit with immunotherapies, particularly when used in combination or a select population, have provided the framework to develop sound clinical trials. Understanding immunogenic modulation, antigen spread, biomarkers, and DNA-repair defects will also help mold future strategies. Through rational patient selection and evidence-based combination approaches, patients with prostate cancer may soon derive durable survival benefits with immunotherapies.

In 2015, fourteen topics were selected as major research advances in gynecologic oncology. For ovarian cancer, high-level evidence for annual screening with multimodal strategy which could reduce ovarian cancer deaths was reported. The best preventive strategies with current status of evidence level were also summarized. Final report of chemotherapy or upfront surgery (CHORUS) trial of neoadjuvant chemotherapy in advanced stage ovarian cancer and individualized therapy based on gene characteristics followed. There was no sign of abating in great interest in immunotherapy as well as targeted therapies in various gynecologic cancers. The fifth Ovarian Cancer Consensus Conference which was held in November 7–9 in Tokyo was briefly introduced. For cervical cancer, update of human papillomavirus vaccines regarding two-dose regimen, 9-valent vaccine, and therapeutic vaccine was reviewed. For corpus cancer, the safety concern of power morcellation in presumed fibroids was explored again with regard to age and prevalence of corpus malignancy. Hormone therapy and endometrial cancer risk, trabectedin as an option for leiomyosarcoma, endometrial cancer and Lynch syndrome, and the radiation therapy guidelines were also discussed. In addition, adjuvant therapy in vulvar cancer and the updated of targeted therapy in gynecologic cancer were addressed. For breast cancer, palbociclib in hormone-receptor-positive advanced disease, oncotype DX Recurrence Score in low-risk patients, regional nodal irradiation to internal mammary, supraclavicular, and axillary lymph nodes, and cavity shave margins were summarized as the last topics covered in this review.

OBJECTIVETo explore the antiviral efficacy, safety and protective ability against mother-to-infant transmission of telbivudine in pregnant patients with chronic hepatitis B (CHB) during the first trimester.

METHODSEighty four gravid women who were diagnosed with CHB, in their first trimester of pregnancy, and had refused to terminate their pregnancies were enrolled; all study participants were clinically classified as active hepatitis cases with positivity for both hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg), HBV DNA more than or equal to 107 copies/mL and serum level of alanine aminotarnsferase (ALT) of more than or equal to 4 ULN.Patients with YMDD mutations were excluded from the study. The study participants were divided into a telbivudine treatment group (n=43; administered in the first trimester of pregnancy) and a control group (n=41, consisting of patients who refused to take antivirals). All babies bom to the women in both groups of the study received standard immune prevention (anti-hepatitis B immunoglobulin plus hepatitis B vaccine) and artificial feeding.Data recorded for the women during pregnancy included clinical findings for tests of hepatic and renal function, myocardial enzymes, blood and urine clinical parameters, hepatitis B virus makers and HBV DNA, as well as notation of any adverse reactions. The neonates were evaluated for presence of HBV infection, parameters of growth and development, presence of complications, and Apgar score. At 6 and 12 months old, all infants were evaluated for HBV DNA level and HBsAg presence.

RESULTSThe genetic variant rtM204I was detected in one of the women in the treatment group at 36 weeks of pregnancy. One woman in the control group developed severe hepatitis at 28 weeks of pregnancy and was put on the telbivudine treatment The treatment group showed greater recovery rates of ALT than the control group at 12 weeks of pregnancy (62.8% vs.29.3%, P=0.002), 24 weeks of pregnancy (76.7% vs.46.3%, P=0.000), and at ante partum (88.1% vs.60.0%, P=0.004). The treatment group also showed greater HBV DNA-negative conversion rates at 12 weeks of pregnancy (20.9% vs.0, P=0.006), at 24 weeks of pregnancy (37.2% vs.0, P=0.001) and at ante partum (78.6% vs.0, P=0.000), and greater HBeAg seroconversion rates at 12 weeks of pregnancy (2.3% vs.0, P=1.000), at 24 weeks of pregnancy (9.3% vs.0, P=0.116) and at ante partum (2 1.4% vs.0, P=0.002). The HBsAg-positive rates and HBV DNA-positive rates among the infants born to the mothers in the treatment and control groups, respectively, were 2.4% vs.17.5% (P=0.027) at birth, 0 vs.17.5% (P=0.005)at 6 months old and 0 vs.17.5% (P=0.005) at 12 months old. The Apgar scores were not significantly different for the children born to the mothers from the two groups, and all the children showed parameters of growth development within normal limits.

CONCLUSIONTelbivudine administration in the first trimester had a good antiviral curative effect and effectively blocked mother-to-infant transmission in women with CHB. The treatment was safe, causing no obvious adverse reaction in the gravid women or developmental effects on the infants.

OBJECTIVETo compare the various combined immunization schemes available for treatment of babies born to mothers with high-load hepatitis B virus (HBV) infection.

METHODSA total of 118 mothers with HBV infection status of hepatitis B surface antigen-positive (HBsAg+), hepatitis B e antigen-positive (HBeAg+) and HBV DNA load of more than 1.0 * 61og10 IU/mL were included in the study. All of the participants' babies received the main-passive immunization therapy according to the wishes of their families. For analysis,the infants were grouped according to the various dosages of the vaccine program (group A: hepatitis B immunoglobulin (HBIG) 200 IU and HBVac 20 mug intramuscular;group B:HBIG 200 IU and HBVac 10 mug intramuscular; group C HBIG 100 IU and HBVac 20 mug intramuscular injection) and times, and followed-up to 7 months of age.All results were statistically analyzed using SPSS software.

RESULTSAll of the infants produced anti-HBs after vaccination.After the HBIG injection schedule was completed in January, the mean concentrations of anti-HBs in groups A, B, and C were 263.56 ± 50.98,231.06 ± 74.07, and 99.23 ± 29.82 mIU/mL respectively;the concentrations were significantly different between groups A and C, and between groups B and C (P < 0.001). In July, the titers of anti-HBs in groups A, B, and C were 788.10 ± 281.96,428.39 ± 347.48, and 708.44 ± 315.69 mIU/mL respectively; the concentrations were significantly different between groups A and B, and between groups B and C (P < 0.05).

CONCLUSIONAdminisWation of the hepatitis B vaccine combined with HBIG at birth can achieve immune protection for babies born to highly viremic mothers. In January, the HBIG dosage of 200 IU was more reliable than 100 IU. The hepatitis B 20 tg dose vaccine was safe and effective.

In North Korea, the prevalence of hepatitis B is high due to natural factors, gaps in vaccination, and the lack of antiviral treatment. Aid projects are urgently needed, however impeded by North Korea's political and economical situation and isolation. The feasibility of a joint North Korean and German humanitarian hepatitis B prevention program was assessed. Part 1: Hepatitis B vaccination catch-up campaign. Part 2: Implementation of endoscopic ligation of esophageal varices (EVL) by trainings in Germany and North Korea. By vaccinating 7 million children between 2010 and 2012, the hepatitis B vaccination gap was closed. Coverage of 99.23% was reached. A total of 11 hepatitis B-induced liver cirrhosis patients (mean age 41.1 yr) with severe esophageal varices and previous bleedings were successfully treated by EVL without major complications. A clinical standard operating procedure, a feedback system and a follow-up plan were developed. The bi-modal preventive strategy was implemented successfully. Parts of the project can serve as an example for other low-income countries, however its general transferability is limited due to the special circumstances in North Korea.
