Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

BACKGROUND: Intensive phototherapy (IPT) and exchange transfusion (ET) are the main treatments for extreme hyperbilirubinemia. However, there is no reliable evidence on determining the thresholds for these treatments. This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia. METHODS: This retrospective cohort study was conducted in seven centers from January 2015 to January 2018. Patients with extreme hyperbilirubinemia that met the criteria of ET were included. Patients were divided into three subgroups (low-, medium-, and high- risk) according to gestational week and risk factors. Propensity score matching (PSM) was performed to balance the data before treatment. Study outcomes included the development of bilirubin encephalopathy, duration of hospitalization, expenses, and complications. Mortality, auditory complications, seizures, enamel dysplasia, ocular motility disorders, athetosis, motor, and language development were evaluated during follow-up at age of 3 years. RESULTS: A total of 1164 patients were included in this study. After PSM, 296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-, medium-, and high-risk subgroups with 188, 364, and 40 matched patients, respectively. No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity, complications, and sequelae. Hospitalization duration and expenses were lower in the low- and medium-risk subgroups in the IPT only group. CONCLUSIONS In this study, our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia. The indication of ET for patients with hyperbilirubinemia could be stricter. However, it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors. If IPT can be guaranteed and proved to be therapeutic, ET should be avoided as much as possible.

Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.

Objective To investigate the status on children of 3-14 years old who suffered from cerebral palsy in Liaoning province. Methods One thousand three hundred and twenty-three cases of children with cerebral palsy of 3-14 years old who received rehabilitation in city hospital, county hospital and community hospital were investigated from January 2013 to October 2016 in 14 cities in Liaoning Province. The proportion of cerebral palsy children in 3-4 years old, 4-5 years old, 8-9 years old, 5-6 years old , 6-7 years old and 7-8 years old was about 10%, and in the other age the proportion was about 7%. The proportion of men and women generally was 4:1;neonatal convulsion (252 cases, 19%), premature delivery (230 cases , 17.3%) and low birth weight infant (187 cases, 14.1%) were main risk factors and accounted for more than 10%. Spastic type cerebral palsy accounted for the highest proportion (54.35%, 719 cases)and ataxia cerebral palsy accounted for the lowest proportion (2.95%). In complications , lower intelligence accounted for the highest proportion (50.34%, 666 cases), followed by the language barrier (43.99% , 582 cases), and the other complications accounted for less than 10%.;gross motor function classification in most studied children was stageⅡ(35%) and stageⅢ(32.50%); 6.95% patients could go to school, and 84.96% patients had health insurance. Patients coming from city accounted for 69.01%, and patients coming from rural area accounted for 30.99%. Mothers′ education below primary school was 4.16% . 36.05% children received rehabilitation in comprehensive hospital, 60.09%in children′s hospital and 3.85%in maternal and child health hospital. Conclusions Spastic cerebral palsy is the main type of children with cerebral palsy in Liaoning.High risk factors include neonatal convulsions, premature birth and low birth weight infants. Most patients complicate with low intelligence and language barriers.This paper can be used as the basis of further research on prevention and treatment

The biological and genetic characteristics of a highly neurovirulent JE virus strain SA4 were studied. Mice were inoculated intracerebrally with strain SA4 and SA14, and observed for 14 days, respectively. On different days, mice brains were harvested for titrations of the virus content in the brains. Full-length genome of SA4 was sequenced and compared with SA14 as well as other JE virus strains in the world. The results indicated that the mice inoculated by SA4 induced sickness and death more rapidly (24 hours faster) than those induced by the SA14. The virus titers in the brains of mice infected with SA4 were 0.5-1.0 lg PFU/mL higher than that infected with SA14. The sequence comparison indicated that the nucleotide and amino acid homology between SA4 and the other 21 JE strains were 84.6%-99.0% and 95.2%-99.7% respectively. Comparison with strain SA14 revealed that there were 17 amino acid differences between the two strains, of which 5 were in the E protein region. The results demonstrate that strain SA4 is a highly neurovirulent strain. The substitutions of the 17 amino acids in the SA4 strain can be the molecular basis for the biological characteristics of high neurovirulence.

CTN-1 is one of the rabies vaccine strains for human use in China, but there has been no report on the full-length gene sequence of CTN-1. In this study, the full-length gene of CTN-1 was amplified by RT-PCR, each PCR product was cloned into T vector and then sequenced, assemblied and compared with other vaccine strains as well as the wild Chinese rabies isolates. The phylogenetic tree of G gene was constructed and the genetic homology was analyzed. The results revealed that CTN-1 was 11 925nt (GenBank accession number: FJ959397)in length and belonged to the genotype I. The full-length nucleotide homologies among CTN-1 and other rabies virus strains were between 81.5%-93.4%, of which the lowest 81.5% was between CTN-1 strain and bat isolate SHBRV, and the highest 93.4% was between CTN-1 and Chinese isolate HN10. The phylogenetic analysis revealed that the majority of Chinese isolates could be grouped into the same clade with the CTN-1 strain, but aG and some vaccine strains from abroad such as Flury, PM, PV, ERA, RC-HL and a few Chinese strains were grouped in another clade. Comparsion of the G protein genes also showed that the homologies among CTN-1 and most of the Chinese isolates were higher than that of the other vaccine strains to those Chinese strains. Therefore, it suggests that the CTN-1 strain is more suitable and rational to be used for the production of rabies inactivated vaccine in China than the others.

Objective To study the viremia formation in guinea-pigs infected with wild type and attenuated Japanese encephalitis virus (JEV). Methods Guniea pigs were inoculated intraperitoneally with different wild JEV strains and the attenuated vaccine strain and its parent virulent strain. Viremia was detected on different days following virus inoculation. Results All the guinea-pigs inoculated with the wild JEV strains induced different levels of viremia ( 1.00-3.40 lg pfu) on the 1 st and 3rd day post inoculation.Using a virus titer of 104 pfu for inoculation, the animals inoculated with the SA14 parent strain induced relatively high viremia (1024-10 3.4 pfu), however no viremia coulds be detected on any tested days.Conclusion The degree of viremia in guinea pigs can be used as a new method to evaluate the attenuation of JEV.

In order to reveal the phenotypic characteristics of 17 JE virus strains isolated from different years, plaque sizes, mice neurovirulence and mice neuroinvasiveness of the isolates were studied and compared. BHK21 cell monolayers were used for testing the plaque sizes. The virus neurovirulence was tested in 9-11g mice inoculated intracerebrally and the virus neuroinvasiveness was tested in 9-11g and 14-16g by subcutaneous inoculation. Results showed that all the viruses produced clear plaques on the BHK21 cell monolayers with different sizes and all the virus strains appeared high neurovirulence in the mice with higher than lg8. 0/0.03 mL virus titers, while no apparent difference among them. The neuroinvasiveness (subcutaneous virulence) tested in the 9-11g mice had shown a little difference, but when tested in the 12-14 g mice,the difference was apparent. The results demonstrated that JEV in nature were highly neurovirulent with no apparent difference. However the neuroinvasiveness of the JEV in nature was greatly different, which didn't relate to the years of isolation and genotypes, but most of the viruses isolated from patients showed higher neuroinvasiveness.
