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.

Objective:This study aims to investigate the expression of uridine diphosphate-glucose[]pyrophos-phorylase 2(UGP2)in breast cancer(BC)tissues and its oncogenic mechanism,assessing its potential value as a diag-nostic and prognostic biomarker for breast cancer.Methods:(1)Online database analysis was conducted to assess UGP2 mRNA and protein expression levels in breast cancer and explore their correlation with clinical characteristics.Im-munohistochemistry(IHC)was used to verify UGP2 expression in human breast cancer tumor tissues and evaluate its relationship with clinicopathological features.(2)Kaplan-Meier survival analysis and COX regression models were used to analyze the impact of UGP2 expression on breast cancer patient prognosis.(3)Bioinformatics methods were em-ployed to investigate the correlation between UGP2 and tumor immune cell infiltration,and to predict the biological func-tions and associated signaling pathways of UGP2 in breast cancer.Results:(1)The mRNA and protein expression levels of UGP2 were upregulated in breast cancer tissues(both P<0.05),and were negatively correlated with ER-positive and PR-positive status(OR<1,P<0.05),while positively correlated with Ki-67 levels and the triple-negative breast cancer(TNBC)subtype(OR>1,P<0.05).(2)Elevated expression levels of UGP2 were associated with poorer survival rates in breast cancer patients(both P<0.05)and were identified as an independent adverse prognostic factor for breast cancer(HR=1.40,P<0.05).(3)Functional analysis results suggested that UGP2 may promote tumor progression by regulating metabolism,hormone signaling,and the immune microenvironment.Additionally,UGP2 expression was negatively cor-related with NK cell activation status and positively correlated with the inhibitory state.Conclusion:UGP2 expression is elevated in breast cancer tissues and is closely associated with poor patient prognosis.It may promote cancer pro-gression through mechanisms such as metabolic reprogramming and immune suppression.UGP2 shows promise as a potential biomarker and therapeutic target in breast cancer,providing a basis for personalized treatment.

Objective To explore the mechanism of electroacupuncture improving myocardial ischemia-reperfusion injury(MIRI),electroacupuncture PC6 Attenuates TRPV1 pathway in spinal cord C5-T6 dorsal root ganglion(DRG)on MIRI rats was observed.Methods After one week of experimental feeding,30 SD rats with normal electrocardiogram were randomly divided into sham-operated group and model group,PC6 group,non-meridian and non-acupuncture group,and PC6+capsaicin(TRPV1 receptor agonist)group,with 6 rats in each group.The MIRI model was prepared by ligation of the left anterior descending(LAD)coronary artery in the other groups.The next day after modeling,electroacupuncture of the"PC6"point in the EA group,electroacupuncture of the caudal"non-meridian non-points"in the the non-meridian non-acupuncture point group,and electroacupuncture of the"PC6"point after intraperitoneal injection of capsaicin in the PC6+capsaicin group,20 min/d for 7 days.ECG was used to record the changes of ST level and LF/HF ratio in rats.Evans blue-TTC double staining and HE staining was used to observe the myocardial infarction area and the changes of myocardial tissue morphology.ELISA was used to detect the levels of serum CK-MB and cTnI.Immunofluorescence staining was used to the phenomenon of sympathetic-sensory coupling with TH-CGRP positive labeling in the DRG of rats.qPCR was to detect the mRNA expression of TRPV1,TH,CGRP,SP,ERK and AKT in rat DRG.Results Compared with the sham-operated group,rats in the model group showed significant higher ST level and LF/HF ratio(both P<0.001),and IA/AAR ratio increased significantly(P<0.0001).Massive inflammatory cell infiltration,serum CK-MB,cTnI levels up-regulated significantly(both P<0.0001).The formation of TH-CGRP-labeled sympathetic budding phenomenon in the DRG and the TRPV1,TH,CGRP in the DRG,SP,ERK,and AKT mRNA expression levels increased significantly(both P<0.01).Compared with the model group,the ECG of the endograft group was significantly improved(both P<0.001).The IA/AAR ratio decreased significantly in PC6 group(P<0.001).The myocardial infarction area reduced significantly(P<0.0001).The levels of serum CK-MB and cTnI down-regulated significantly(both P<0.0001),and the phenomenon of sympathetic sprouting within DRG was not evident,and the DRG of the 6 corresponding mRNA expression decreased significantly(both P<0.01).Compared with the PC6 group,the effect of treatment was not obvious in the non-meridian and non-acupuncture group and PC6+capsaicin group,and the electrocardiogram,IA/AAR ratio,myocardial infarcted area,and serum CK-MB,and cTnI levels did not improve(both P<0.01),and a large number of sympathetic budding phenomena were seen in the DRG.The expression of the mRNA corresponding to the phase of 6 increased significantly(both P<0.01).Conculsion Electroacupuncture PC6 may reduce myocardial injury by inhibiting TRPV1 pathway-mediated sympatheticsprouting in dorsal root ganglia.

Objective:To explore the advantages of robotic-arm assisted total hip arthroplasty (rTHA) in acetabular component positioning and lower limb length assessment in patients with severe pelvic coronal tilt.Methods:A retrospective analysis was conducted on the data of 122 patients with unilateral end-stage hip disease and coronal pelvic tilt angle >3° who underwent total hip arthroplasty (THA) at the First Medical Center of PLA General Hospital from June 2022 to December 2023. Among them, 44 patients underwent rTHA, and 78 underwent manual THA (mTHA). The rTHA group included 18 males and 26 females, with an average age of 60.5±9.3 years; the mTHA group included 41 males and 37 females, with an average age of 58.5±8.4 years. Compare the differences in the anteversion angle, abduction angle, pelvic tilt angle, leg length discrepancy (LLD) of the acetabular prosthesis, and the proportions of patients with LLD>0.5 cm and >1 cm between the two groups of patients after surgery. Calculate the proportion of outlier rates of acetabular abduction angle (<30° or >45°), and proportions within Callanan's safe zone. The early efficacy of the hip joint was evaluated by using the modified Harris score and joint range of motion.Results:All patients were followed up for 6 to 12 months, with an average of 8 months. All the surgical incisions of the patients achieved primary healing. Postoperative comparisons showed no statistically significant differences in acetabular abduction angle (39.5°±3.3° vs. 38.4°±7.3°) or anteversion angle (20.7°±1.6° vs. 19.7°±1.6°) between rTHA and mTHA groups ( P>0.05). However, pelvic tilt angle [2.5° (1.1°, 3.6°) vs. 3.5° (2.3°, 5.9°)] showed a statistically significant difference ( U=4.371, P=0.008). The rTHA group exhibited smaller absolute LLD [0.2 (0.1, 0.4) cm vs. 0.5 (0.2, 0.5) cm] and lower proportions of LLD >0.5 cm [14% (6/44) vs. 49% (38/78)] and >1 cm [2% (1/44) vs. 18% (14/78)], with statistical significance ( P<0.05). The rTHA group had a lower outlier rate for acetabular abduction angle (<30°or >45°) compared to the mTHA group [2% (1/44) vs. 33% (26/78)], with statistical significance (χ 2=10.388, P<0.001). Taking the Callanan safety zone as the standard, the proportion of acetabular cups within the safe zone was significantly higher in the rTHA group (98%, 43/44) compared to the mTHA group (67%, 52/78), with a statistically significant difference (χ 2=13.998, P<0.001). The modified Harris score and hip joint range of motion in the mTHA group increased from 47.6±6.6 points and 83° (73°, 88°) before the operation to 83.5±11.2 points and 118° (110°, 122°) at the last follow-up, respectively. The rTHA group increased from 46.5±9.2 points and 79° (71°, 90°) before the operation to 85.0±12.5 points and 124° (116°, 130°) at the last follow-up. The differences in the modified Harris score and hip joint range of motion between the two groups before the operation and at the last follow-up were statistically significant ( P<0.05). However, there was no statistically significant difference between the groups at the last follow-up ( P>0.05). No THA-related complications occurred during follow-up period. Conclusion:For patients with end-stage hip joint diseases with coronal tilt exceeding 3°, robotic-assisted technology significantly improves the accuracy of acetabular component placement during THA and offers better control of postoperative LLD.

Objective To investigate the relationship between cystatin C(CysC)/prealbumin(PAB)ratio and lung function and chronic obstructive pulmonary disease(COPD)assessment test(CAT)score in patients with COPD.Methods A total of 216 COPD patients admitted to the hospital from February 2021 to February 2024 were selected as the study group,and 150 healthy subjects were selected as the control group during the same period.CysC and PAB levels were detected by immunoturbidimetry,CysC/PAB ratio was calculated,lung function was detected and CAT scores were recorded.Pearson correlation was used to analyze the rela-tionship between CysC/PAB ratio,lung function and CAT score in COPD patients.Results The CysC and CysC/PAB ratio in the study group was significantly higher than that in the control group,and the level of PAB was significantly lower than that in the control group,with statistical significance(P＜0.05).The forced expiratory volume in the first second as a percentage of predicted value(FEV1％pred),the percentage of pre-dicted forced vital capacity(FVC％pred)and the ratio of the first second forced expiratory volume to forced vital capacity(FEV1/FVC)of the study group were lower than those of the control group,and the CAT score of the study group was higher than that of the control group,with statistical significance(P＜0.05).The Cy-sC/PAB ratio and CAT score of COPD patients with the global initiative for chronic obstructive lung disease(GOLD)grade 4 were significantly higher than those with GOLD grade 3,GOLD grade 2 and GOLD grade 1,and the difference was statistically significant(P＜0.05).The ratio of CysC/PAB in very severely affected pa-tients was higher than that in severely affected,moderately affected and mildly affected patients,while the ra-tio of FEV1％pred,FVC％pred and FEV1/FVC was lower than that in severely affected,moderately affected and mildly affected patients,and the difference was statistically significant(P＜0.05).In COPD patients,Cy-sC/PAB ratio was negatively correlated with FEV1％pred,FVC％pred,FEV1/FVC,and positively correlated with CAT score(P＜0.05).Conclusion CysC/PAB ratio is highly expressed in COPD patients,and its level is related to lung function and CAT score,which can reflect the degree of disease and quality of life in COPD patients to a certain extent.
