Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

From October 2021 to February 2023, we retrospectively analyzed the clinical and laboratory data of six patients (three male and three female, median age: 54 years, age range: 29-73 years) with mast cell leukemia (MCL) diagnosed in the First Affiliated Hospital of Soochow University (The Mastocytosis Collaborative Network of China). All patients had acute MCL, with at least one C-finding present. The main clinical presentations were hypoalbuminemia ( n=4), fatigue ( n=3), fever ( n=2), abdominal discomfort ( n=2), osteolytic lesions ( n=2), dizziness ( n=1), skin flushing ( n=1), and weight loss ( n=1). Splenomegaly and lymphadenopathy were noted in six and three patients, respectively. Six patients were strongly positive for CD117, five were positive for CD30 and CD25, and four were positive for CD2. Four patients had a normal karyotype and two patients had an abnormal karyotype. Gene mutations were detected in 4/6 cases. The median serum tryptase level was 24.9 (range: 20.1-171.9) μg/L. Two patients were treated with venetoclax and azacitidine for induction (one patient achieved partial remission by combination with afatinib, while there was no remission after combination with dasatinib in the other patient). Two patients did not achieve complete remission despite treatment with cladribine and imatinib, respectively. One patient treated with interferon combined with glucocorticoids was lost to follow-up, and one patient abandoned treatment. The follow-up time ranged from 1.1 to 21.7 months. Three patients died and two survived. Overall, MCL is a rare subtype of systemic mastocytosis with heterogeneous clinical course, and these patients have poor outcome. A better understanding of the clinical characteristics, treatment, and prognosis of MCL is urgently needed.

Purpose: The prognosis of patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT) is extremely poor, and systemic therapy is currently the mainstream treatment. This study aimed to assess the efficacy and safety of lenvatinib combined with anti–programmed cell death-1 antibodies and transcatheter arterial chemoembolization (triple therapy) in patients with HCC and PVTT. Materials and Methods: This retrospective multicenter study included patients with HCC and PVTT who received triple therapy, were aged between 18 and 75 years, classified as Child-Pugh class A or B, and had at least one measurable lesion. The overall survival (OS), progression-free survival (PFS), objective response rates, and disease control rates were analyzed to assess efficacy. Treatment-related adverse events were analyzed to assess safety profiles. Results: During a median follow-up of 11.23 months (range, 3.07 to 34.37 months), the median OS was greater than 24 months, and median PFS was 12.53 months. The 2-year OS rate was 54.9%. The objective response rate and disease control rate were 69.8% (74/106) and 84.0% (89/106), respectively; 20.8% (22/106) of the patients experienced grade 3/4 treatment-related adverse events and no treatment-related deaths occurred. The conversion rate to liver resection was 31.1% (33/106), with manageable postoperative complications. The median OS was not reached in the surgery group, but was 19.08 months in the non-surgery group. The median PFS in the surgery and non-surgery groups were 20.50 and 9.00 months, respectively. Conclusion Triple therapy showed promising survival benefits and high response rates in patients with HCC and PVTT, with manageable adverse effects.

Transjugular intrahepatic portosystemic shunt (TIPS) is a safe and effective method for the treatment of portal hypertension complications in patients with decompensated liver cirrhosis. At present, there are many prognostic scoring tools for risk stratification of poor prognosis after TIPS. This article briefly introduces seven prognostic scoring tools commonly used for TIPS and summarizes the clinical research evidence of each scoring tool. The literature review shows that there is currently no sufficient research evidence to determine the optimal prognostic scoring tool after TIPS. Future clinical studies should comprehensively explore the advantages and disadvantages of different scoring tools in predicting short- and long-term adverse prognostic events after TIPS and develop new prognostic scoring tools in combination with new prognostic markers.

Objective:To improve the ability of identification and differential diagnosis of severe systemic lupus erythematosus (SLE).Methods:A severe SLE patient with lupus myocarditis, neuropsychiatric lupus, thrombotic microangiopathy (TMA) and other multiple system involvement was reported and discussed.Results:A young female patient developed albuminuria 5 months ago, edema of both lower limbs 3 months ago, change of consciousness 1 month ago and two convulsions attack 2 days ago. She experienced life threatening manifestations such as neuropsychiatric lupus, myocardial involvement of lupus, and TMA. During the course, her condition was generally improved after glucocorticoid pulse therapy and plasma exchange.Conclusion:Various complicated clinical manifestations related to SLE need to be recognized earlier and intervened as soon as possible.

Objective:To clarify the infection and epidemic characteristics of the human metapneumovirus (HMPV) in Chinese patients with febrile respiratory syndrome (FRS), and to provide important baseline data for clinical diagnosis, treatment, prevention and control of HMPV-induced respiratory tract diseases in China.Methods:FRS cases from January 2009 to June 2021 in 9 provinces in China, including Beijing, Hebei, Jilin, Shandong, Shaanxi, Xinjiang, Anhui, Guangdong, Hunan were retrospectively analyzed for their respiratory samples, clinical and epidemic data.The respiratory samples were detected for HMPV by quantitative real-time PCR.Results:A total of 11 660 cases were tested for HMPV, involving 296 (2.54%) HMPV-positive cases.Among 296 HMPV-positive cases, 218 were single HMPV infection, and 78/296 (26.35%) were co-infected with one or more respiratory viruses.HMPV mainly affected children under 5 years of age (3.10%), and in this population, the proportion of pneumonia in HMPV co-infection cases was significantly higher than that of single HMPV infection.HMPV could be detected all year round, which was more popular in winter and spring, with the peak of HMPV epidemic in March.Conclusions:HMPV is one of the important pathogens causing acute respiratory infection in children, showing a clear seasonal epidemic.HMPV can be infected alone or in combination with other respiratory viruses, which may increase the risk of pneumonia in children.

Acute myeloid leukaemia (AML) is the most common form of acute leukaemia in adults, with increasing incidence with age and a generally poor prognosis. Almost 20% of AML patients express mutant isocitrate dehydrogenase 2 (mIDH2), which leads to the accumulation of the carcinogenic metabolite 2-hydroxyglutarate (2-HG), resulting in poor prognosis. Thus, global institutions have been working to develop mIDH2 inhibitors. SH1573 is a novel mIDH2 inhibitor that we independently designed and synthesised. We have conducted a comprehensive study on its pharmacodynamics, pharmacokinetics and safety. First, SH1573 exhibited a strong selective inhibition of mIDH2 R140Q protein, which could effectively reduce the production of 2-HG in cell lines, serum and tumors of an animal model. It could also promote the differentiation of mutant AML cell lines and granulocytes in PDX models. Then, it was confirmed that SH1573 possessed characteristics of high bioavailability, good metabolic stability and wide tissue distribution. Finally, toxicological data showed that SH1573 had no effects on the respiratory system, cardiovascular system and nervous system, and was genetically safe. This research successfully promoted the approval of SH1573 for clinical trials (CTR20200247). All experiments demonstrated that, as a potential drug against mIDH2 R140Q acute myeloid leukaemia, SH1573 was effective and safe.

Malaysia is a multi-ethnic and multi-cultural constitutional monarchy and federal system located in Southeast Asia. The top three diseases that cause deaths are ischemic heart disease, lower respiratory tract infections and stroke. Lower respiratory tract infections, colorectal cancer and Alzheimer’s disease have been the fastest growing diseases in recent years. The health insurance system complements public and private health care system. Traditional medicine in Malaysia includes Malaysian Medicine, Traditional Chinese Medicine (TCM), Indian Medicine, Islamic Medicine and homeopathy. Although TCM, such as acupuncture, has not been covered by health insurance, it is widely used under the impetus of the local Chinese people. At present, in Malaysia, the TCM public acceptance and education need promotion, and scientific researches need to be improved. It is hoped that in the future, the development of TCM in Malaysia will be better developed and disseminated by promoting TCM relevant legislation, increasing public awareness, focusing on education and training, and carrying out international scientific research cooperation.

OBJECTIVEOn the basic therapy, to assess the clinical effects of dynamic scalp acupuncture, scalp acupuncture combined with proprioceptive neuromuscular facilitation (PNF) therapy and simple PNF therapy for upper limb motor impairment in ischemic post-stroke spastic hemiplegia.

METHODSA total of 90 cases were randomly assigned into a PNF group, a dynamic scalp acupuncture group and a scalp acupuncture group, 30 cases in each group. Basic therapy and PNF therapy were applied in the three groups. PNF therapy was used during scalp acupuncture in the dynamic scalp acupuncture group. PNF therapy was applied after scalp acupuncture in the scalp acupuncture group. The points were the upper 1/5 and middle 2/5 of (MS 6) and (MS 7) at the lesion side, the hemiparalysis contralateral side. The treatment was given for 6 months, once a day and 1 month as a course. The modified Ashworth scale (MAS), the Fugl-Meyer motor assessment (FMA) and Barthel index (BI) were observed before treatment and 2 weeks, 1 month, 3 months, and 6 months after treatment.

RESULTSThe MAS 1 month, 3 months and 6 months after treatment were improved compared with those before treatment in the three groups ( all <0.05), and the MAS results in the dynamic scalp acupuncture group were better than those in the PNF and scalp acupuncture group (all <0.05). The FMA and BI scores 1 month, 3 months and 6 months after treatment were higher than those before treatment (all <0.05). The FMA Scores in the 3 time points and after treatment in the dynamic scalp acupuncture group were higher than those in the other two groups (all <0.05).

CONCLUSIONPNF therapy during scalp acupuncture can relieve the spasmodic condition of patients with upper limb motor impairment in ischemic post-stroke spasmodic hemiplegia, and improve the limb function and life activity, which is better than PNF therapy after scalp acupuncture and simple PNF therapy.
