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.

Hypertension and osteoporosis(OP)are common diseases in middle-aged and elderly people,and the number of patients with both diseases has gradually increased in recent years.Because the onset of the disease is hidden,it is easy to cause fractures and serious complications of heart,brain and kidney in the later stage,which not only seriously damages the quality of life of patients,but also increases the difficulty of clinical treatment.Therefore,it is particularly necessary to strengthen the research on this disease.More and more studies have found that the disorder of intestinal flora will lead to the occurrence of OP,while the intestinal flora of patients with hypertension is obviously out of balance.Therefore,this paper thinks that intestinal flora may be the key influencing factor of hypertension complicated with OP,and the imbalance of intestinal flora will lead to the imbalance of short-chain fatty acid metabolism,immune inflammatory reaction and increased sympathetic nerve activity,thus causing the imbalance of bone homeostasis and promoting the occurrence of OP.Therefore,it is suggested that regulating intestinal flora may be a new way to intervene hypertension complicated with OP.

Objective To observe the effects of Zhengan Xifeng decoction on bile acid spectrum of bile and sterol 12α hydroxylase(CYP8B1)in spontaneously hypertensive rats(SHR).Methods Fifty SHR were randomly divided into model group,control group(1.0 mg·kg-1·d-1 benazepril by gavage)and experimental-L,-M,-H groups(8.63,17.25 and 34.50 g·kg-1·d-1 Zhengan Xifeng decoction by gavage),another 10 homologous male Wistar-Kyoto(WKY)rats were taken as the normal group.The model group and the normal group were given the same amount of distilled water.The rats in the 6 groups were administered once a day for 8 weeks.The animal non-invasive sphygmomanometer was used to measure the blood pressure of rats in each group by tail-cuff method;the bile acid spectrum of rats in each group was detected by UPLC-MS/MS;the expression of CYP8B1 mRNA in rat liver tissue was detected by real-time fluorescence quantitative polymerase chain reaction.Results The systolic blood pressure at the 8th week of the experimental-M,-H groups,control group,model group,normal group were(169.63±12.10),(170.32±9.64),(175.95±15.47),(189.47±7.42)and(146.40±9.45)mmHg;the diastolic blood pressure at the 8th week were(135.10±11.99),(129.73±15.10),(135.18±17.62),(149.20±8.83)and(110.53±10.92)mmHg;the relative expression levels of CYP8B1 mRNA were 3.36±0.94,5.45±1.46,4.29±0.95,0.89±0.14 and 1.00±0.00,respectively.Compared with the model group,the above indexes in the experimental-M,-H groups were statistically significant(P＜0.01,P＜0.05).Compared with the model group,the bile acid spectrum of experimental-L,-M,-H groups bile changed significantly,and a total of 9 different bile acids were found,which were hyodeoxycholic acid,glycohyodeoxycholic acid,glycochenodeoxycholic acid,glycoursodeoxycholic acid,α-muricholic acid,ursodeoxycholic acid,cholic acid,β-muricholic acid and glycocholic acid.Conclusion Zhengan Xifeng decoction may correct bile acid spectrum disorder of bile and reduce blood pressure by up-regulating liver CYP8B1 expression.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

Glyceryl phenylbutyrate(GPB)serves as a long-term management medication for Ornithine transcarbamylase deficiency(OTCD),effectively controlling hyperammonemia,but there is a lack of experience in using this medicine in China.This article retrospectively analyzes the case of a child diagnosed with OTCD at Shanghai Children's Medical Center,Shanghai Jiao Tong University School of Medicine,including a review of related literature.After diagnosis,the patient was treated with GPB,followed by efficacy follow-up and pharmacological monitoring.The 6-year and 6-month-old male patient exhibited poor speech development,disobedience,temper tantrums,and aggressive behavior.Blood ammonia levels peaked at 327 μmol/L;urine organic acid analysis indicated elevated uracil levels;cranial MRI showed extensive abnormal signals in both cerebral hemispheres.Genetic testing revealed de novo mutation in the OTC gene(c.241T＞C,p.S81P).Blood ammonia levels were approximately 43,80,and 56 μmol/L at 1,2,and 3 months after starting GPB treatment,respectively.During treatment,blood ammonia was well-controlled without drug-related adverse effects.The patient showed improvement in developmental delays,obedience,temperament,and absence of aggressive behavior.

Objective To observe the effects of Zhengan Xifeng decoction on bile acid-Takeda G protein-coupled receptor 5(TGR5)/Ras homolog(Rho)/Rho-associated coiled-coil containing protein kinase(ROCK)/agouti-related protein(AgRP)signaling pathway in spontaneously hypertensive rats(SHR).Methods Seventy SHR were randomly divided into the model group,control group(gavage administration of 0.5 mg·kg-1·d-1 amlodipine besylate tablets),experimental-L,-M,-H group(gavage administration of 8.630 x 103,1.725 × 104,3.450 × 104 mg·kg-1·d-1 Zhengan Xifeng decoction).Fifteen Wistar-Kyoto rats served as the normal group.The model and normal groups were given the same amount of distilled water.Six groups were treated for 8 weeks with once a day.The bile acid profiles of jejunum contents and colon contents were detected by ultra-high-performance liquid chromatography-tandem mass spectrometry,and the expression levels of TGR5,Rho,ROCK and AgRP proteins in the hypothalamus were detected by Western blot.Results Compared with the normal,mode,control groups and experimental-L,-M,-H groups,the bile acid spectrum of jejunum contents was significantly changed,and 6 different bile acids were found,namely glycoursodeoxycholic acid,glycohyodeoxycholic acid,hyodeoxycholic acid,ursodeoxycholic acid,taurochenodeoxycholic acid and chenodeoxycholic acid.The bile acid spectrum of colon contents was significantly changed,and 4 different bile acids were found,namely deoxycholic acid,ursodeoxycholic acid,lithocholic acid and hyodeoxycholic acid.The relative expression levels of TGR5 protein in normal,model,control and experimental-M groups were 1.01±0.22,0.75±0.23,0.96±0.16 and 1.02±0.21;the relative expression levels of Rho protein were 0.81±0.14,0.58±0.19,0.83±0.27 and 0.94±0.24;the relative expression levels of ROCK protein were 0.99±0.27,0.65±0.13,1.07±0.22 and 1.06±0.24;the relative expression levels of AgRP protein were 0.98±0.33,1.46±0.45,0.83±0.25 and 0.95±0.33,respectively.Compared with the model group,the above indexes in the experimental-M group and the normal group showed significant differences(all P＜0.05).Conclusion Zhengan Xifeng decoction may suppress AgRP expression via bile acid-TGR5/Rho/ROCK/AgRP signaling pathway,to achieve the purpose of reducing blood pressure.

Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.
