BACKGROUND:
Progressive lipid loss of adipose tissue is a major feature of cancer-associated cachexia. In addition to systemic immune/inflammatory effects in response to tumor progression, tumor-secreted cachectic ligands also play essential roles in tumor-induced lipid loss. However, the mechanisms of tumor-adipose tissue interaction in lipid homeostasis are not fully understood.
METHODS:
The yki -gut tumors were induced in fruit flies. Lipid metabolic assays were performed to investigate the lipolysis level of different types of insulin-like growth factor binding protein-3 (IGFBP-3) treated cells. Immunoblotting was used to display phenotypes of tumor cells and adipocytes. Quantitative polymerase chain reaction (qPCR) analysis was carried out to examine the gene expression levels such as Acc1 , Acly , and Fasn et al .
RESULTS:
In this study, it was revealed that tumor-derived IGFBP-3 was an important ligand directly causing lipid loss in matured adipocytes. IGFBP-3, which is highly expressed in cachectic tumor cells, antagonized insulin/IGF-like signaling (IIS) and impaired the balance between lipolysis and lipogenesis in 3T3-L1 adipocytes. Conditioned medium from cachectic tumor cells, such as Capan-1 and C26 cells, contained excessive IGFBP-3 that potently induced lipolysis in adipocytes. Notably, neutralization of IGFBP-3 by neutralizing antibody in the conditioned medium of cachectic tumor cells significantly alleviated the lipolytic effect and restored lipid storage in adipocytes. Furthermore, cachectic tumor cells were resistant to IGFBP-3 inhibition of IIS, ensuring their escape from IGFBP-3-associated growth suppression. Finally, cachectic tumor-derived ImpL2, the IGFBP-3 homolog, also impaired lipid homeostasis of host cells in an established cancer-cachexia model in Drosophila . Most importantly, IGFBP-3 was highly expressed in cancer tissues in pancreatic and colorectal cancer patients, especially higher in the sera of cachectic cancer patients than non-cachexia cancer patients.
CONCLUSION
Our study demonstrates that tumor-derived IGFBP-3 plays a critical role in cachexia-associated lipid loss and could be a biomarker for diagnosis of cachexia in cancer patients.

OBJECTIVES:
To investigate the nutritional status and its influencing factors in children with newly diagnosed inflammatory bowel disease (IBD).
METHODS:
A retrospective analysis was conducted on the clinical data of children who were diagnosed with IBD for the first time in Hunan Children's Hospital from January 2015 to December 2021. Diagnostic delay was defined as the time from the symptom onset to IBD diagnosis being in the upper quartile (P76-P100) of all IBD children in the study. Multivariate logistic regression analysis was used to explore the risk factors for emaciation and growth retardation.
RESULTS:
A total of 125 children with newly diagnosed IBD were included, with Crohn's disease being the main type (91.2%). The rates of emaciation and growth retardation were 42.4% (53 cases) and 7.2% (9 cases), respectively, and the rate of anemia was 77.6% (97 cases). Diagnostic delay was noted in 31 children (24.8%), with the time from the symptom onset to IBD diagnosis of 366 to 7 211 days. Multivariate logistic regression analysis showed that diagnostic delay was a risk factor for emaciation and growth retardation (OR=2.73 and OR=4.42, respectively; P<0.05) and that age was positively associated with emaciation (OR=1.30, P<0.05).
CONCLUSIONS
Children with newly diagnosed IBD have poor nutritional status, and the rates of anemia, emaciation, and growth retardation are high. Diagnostic delay is associated with malnutrition in children with IBD.

Obesity is a global public health problem that imposes a heavy economic burden on society. The current main strategies for treating obesity include lifestyle interventions, pharmacological treatments, endoscopic treatments and metabolic surgery. With the development of medical technology, weight reduction by intragastric occupancy devices represented by intragastric balloons and intragastric capsules are gradually emerging. Intragastric balloons are used to reduce weight by occupying the volume of the stomach with balloons filled with different volumes of gas or liquid, among which ReShape, Orbera, Obalon, Elipse and Spatz balloons are gradually used in patients with mild to moderate obesity due to their non-invasive, high safety and reusable advantages. Intragastric capsules are recommended in overweight and obese patients for weight loss through hydrogels with transient superabsorbent swelling properties and completely noninvasive. Both approaches achieve weight loss by limiting gastric volume, increasing satiety and reducing food intake. Despite the presence of adverse gastrointestinal events associated with nausea, vomiting, and abdominal distention, they offer new ideas for the non-invasive clinical treatment of obesity.

Introduction:
The demanding nature of medical school causes students to experience stress, anxiety,
and depressive episodes that may cause students to gain or lose weight. This study aimed to determine
the association of weight changes and stress levels among a private medical school students.
Methods:
Data were collected two times with an interval of 30 days through on-site measurement of the
students’ anthropometrics using a stadiometer and utilization of online survey questionnaires accessed
via QR code. Demographics and disease states were identified in the first round of data collection while
the Perceived Stress Scale-10 (PSS-10) and identification of stressors was integrated in the second round
of data collection.
Results:
Among the 212 individuals, 69.8% were categorized into having perceived moderate stress levels,
22.2% with high stress, and 8% with low stress. Of the 212 cases, 86 gained weight, 91 lost weight, and
35 had no change in weight. Fear of failure, poor motivation, and difficulty understanding lectures are
among the top overall stressors. The study noted that there is a moderate association between stress
and weight changes but it is not enough to reach statistical significance (0.161), as the sample size
was not reached. The study revealed that the prevailing diseases were Polycystic Ovarian Syndrome,
Hypothyroidism, and Hypertension, which have varying degrees of impact on weight change.
Conclusion
There is an association between weight changes and stress levels among first to fourth year
medical students of a private medical school from A.Y. 2023-2024.

OBJECTIVE:
To investigate the effectiveness of osteotomy of non-core weight-bearing area of the lateral tibial plateau, reduction, and internal fixation in the treatment of tibial plateau fractures involving posterolateral column collapse.
METHODS:
A clinical data of 23 patients with tibial plateau fractures involving posterolateral column collapse, who had undergone osteotomy of non-core weight-bearing area of the lateral tibial plateau, reduction, and internal fixation between January 2015 and June 2021, was retrospectively analyzed. There were 14 males and 9 females with an average age of 42.6 years ranging from 26 to 62 years. The causes of injury included traffic accident in 16 cases, falling from height in 5 cases, and other injuries in 2 cases. According to Schatzker classification, there were 15 cases of type Ⅴ and 8 cases of type Ⅵ. The time from injury to operation was 4-8 days with an average of 5.9 days. The operation time, intraoperative blood loss, fracture healing time, and complications were recorded. The depth of articular surface collapse of posterolateral column and posterior inclination angle (PSA) of the tibial plateau were compared before operation and at 2 days and 6 months after operation; fracture reduction of tibial plateau fracture was evaluated by Rasmussen anatomic score. The recovery of knee function was evaluated by Hospital for Special Surgery (HSS) score at 2 days and 6 months after operation.
RESULTS:
All 23 patients were completed the operation successfully. The operation time was 120-195 minutes, with an average of 152.8 minutes; the intraoperative blood loss was 50-175 mL, with an average of 109.5 mL. All patients were followed up 12-24 months, with an average of 16.7 months. One patient had superficial wound infection after operation, and the incision healed after dressing change; primary healing of incision of other patients was obtained. The fracture healing time was 12-18 weeks, with an average of 13.7 weeks. No failure of internal fixation, varus and valgus deformity of the knee joint, and instability of the knee joint was found at last follow-up. One patient developed joint stiffness and the range of motion of the knee joint was 10°-100°; the range of motion of the knee joint of other patients was 0°-125°. At 2 days and 6 months after operation, the depth of articular surface collapse of posterolateral column, PSA, and Rasmussen anatomic scores significantly improved when compared with those before operation ( P<0.05). There was no significant difference between the two postoperative time points ( P>0.05). The HSS score at 6 months after operation was significantly higher than that at 2 days after operation ( P<0.05).
CONCLUSION
For tibial plateau fractures involving posterolateral column collapse, reduction and internal fixation through osteotomy of non-core weight-bearing area of the lateral tibial plateau has the advantages of fully expose the posterolateral column fragment, good articular surface reduction, sufficient bone grafting, and fewer postoperative complications. It is beneficial to restore knee joint function and can be widely used in clinic.

OBJECTIVES:
To compare the effect of different frequency of acupoint thread-embedding on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention.
METHODS:
A total of 126 subjects with overweight/obesity of spleen deficiency and dampness retention were randomized into a 2-week group(63 cases, 13 cases dropped out)and a 3-week group(63 cases, 11 cases dropped out, 1 case was eliminated). The two groups were treated with acupoint thread-embedding once every 2 weeks and once every 3 weeks respectively, Zhongwan(CV 12), Shuifen(CV 9), Qihai(CV 6), Guanyuan(CV 4) and bilateral Zhangmen(LR 13), Tianshu(ST 25), Liangmen(ST 21), Daheng(SP 15), Fujie(SP 14), Pishu(BL 20), Yinlingquan(SP 9)were selected. Four times were required in the two groups. Before and after treatment, follow-up after 2 months of treatment completion, the body mass index(BMI), body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, fat percentage(F%), skin fold thickness were observed in the two groups.
RESULTS:
After treatment and in follow-up, the BMI, body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, F%, skin fold thickness in the two groups were decreased compared with those before treatment (P<0.001, P<0.01), the changes of BMI, body weight, obesity degree, F%, skin fold thickness in the 2-week group were larger than those in the 3-week group(P<0.05, P<0.01, P<0.001).
CONCLUSIONS
The effect of acupoint thread-embedding once every 2 weeks on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention is superior to that once every 3 weeks.

Post-traumatic stress disorder (PTSD) has been reported to be associated with a higher risk of cardiovascular disease. The amygdala may have an important role in regulating cardiovascular function. This study aims to explore the effect of amygdala glutamate receptors (GluRs) on cardiovascular activity in a rat model of PTSD. A compound stress method combining electrical stimulation and single prolonged stress was used to prepare the PTSD model, and the difference of weight gain before and after modeling and the elevated plus maze were used to assess the PTSD model. In addition, the distribution of retrogradely labeled neurons was observed using the FluoroGold (FG) retrograde tracking technique. Western blot was used to analyze the changes of amygdala GluRs content. To further investigate the effects, artificial cerebrospinal fluid (ACSF), non-selective GluR blocker kynurenic acid (KYN) and AMPA receptor blocker CNQX were microinjected into the central nucleus of the amygdala (CeA) in the PTSD rats, respectively. The changes in various indices following the injection were observed using in vivo multi-channel synchronous recording technology. The results indicated that, compared with the control group, the PTSD group exhibited significantly lower weight gain (P < 0.01) and significantly decreased ratio of open arm time (OT%) (P < 0.05). Retrograde labeling of neurons was observed in the CeA after microinjection of 0.5 µL FG in the rostral ventrolateral medulla (RVLM). The content of AMPA receptor in the PTSD group was lower than that in the control group (P < 0.05), while there was no significant differences in RVLM neuron firing frequency and heart rate (P > 0.05) following ACSF injection. However, increases in RVLM neuron firing frequency and heart rate were observed after the injection of KYN or CNQX into the CeA (P < 0.05) in the PTSD group. These findings suggest that AMPA receptors in the amygdala are engaged in the regulation of cardiovascular activity in PTSD rats, possibly by acting on inhibitory pathways.

With the increasing number of obese patients worldwide, metabolic and bariatric surgery (MBS) has quickly become an effective way to treat obesity and related metabolic diseases such as type 2 diabetes, hypertension, lipid abnormalities, etc. Although MBS has become an important part of general surgery, there is still controversy regarding the indications for MBS. In 1991, the National Institutes of Health (NIH) issued a statement on the surgical treatment of severe obesity and other related issues, which continues to be the standard for insurance companies, health care systems, and hospital selection of patients. The standard no longer reflects the best practice data and lacks relevance to today's modern surgeries and patient populations. After 31 years, in October 2022, the American Society for Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO), the world's leading authorities on weight loss and metabolic surgery, jointly released new guidelines for MBS indications, based on increasing awareness of obesity and its comorbidities and the accumulation of evidence of obesity metabolic diseases. In a series of recommendations, the eligibility of patients for bariatric surgery has been expanded. Specific key updates include the following: (1) MBS is recommended for individuals with BMI≥35 kg/m2, regardless of the presence, absence, or severity of co-morbidities; (2) MBS should be considered for individuals with metabolic diseases and BMI 30.0-34.9 kg/m2; (3) the BMI threshold should be adjusted for the Asian population:: BMI≥25 kg/m2 suggest clinical obesity, and BMI ≥ 27.5 kg/m2 population should consider MBS; (4) Appropriately selected children and adolescents should be considered for MBS.

9.The efficacy and safety of glucocorticoid stent implantation compared with oral glucocorticoid during perioperative period in chronic rhinosinusitis with nasal polyps.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2023;37(11):878-885
Objective:To compare the perioperative efficacy and safety of postoperative oral glucocorticoid and glucocorticoid stent implantation in patients with chronic rhinosinusitis with nasal polyps(CRSwNP) undergoing functional endoscopic sinus surgery(FESS). Methods:Sixty patients with bilateral CRSwNP with similar degree of lesions were selected and divided into three groups: conventional surgical treatment group(20 cases), glucocorticoid stent group(20 cases), and oral glucocorticoid group(20 cases). All three groups underwent routine FESS, patients in the sinus glucocorticoid stent group receiving sinus glucocorticoid stent placed in the ethmoid sinuses(one on each side) during surgery, and patients in the oral glucocorticoid group received postoperative oral methylprednisolone at a dose of 0.4 mg/kg per day for 7 days, followed by a tapering of 8 mg per week to 8 mg followed by maintenance therapy for 1 week, for a total of 3-4 weeks. Visual analog scale(VAS) scores were used to evaluate nasal congestion, rhinorrhea, olfaction, and facial pressure symptoms before surgery, as well as at 2, 4, 8, and 12 weeks after surgery. Nasal endoscopic Lund-Kennedy scores were recorded, and adverse reactions such as stent detachment, stent-related allergic reactions, sleep disorders, edema, gastrointestinal symptoms, rash/acne, behavioral/cognitive changes, weight gain, limb pain, and infection risk were documented. Results:The nasal congestion symptom scores at 2, 4, 8, and 12 weeks after surgery were significantly lower than those before operationin all three groups, and the differences were statistically significant(P<0.05). The sinus glucocorticoid stent group exhibited significantly lower nasal congestion symptom scores at 4 and 8 weeks after surgery compared to the conventional surgical treatment group. The rhinorrhea symptom scores at 2, 8, and 12 weeks after surgery were significantly lower than preoperative scores in all three groups. Additionally, the sinus glucocorticoid stent group had significantly lower rhinorrhea scores than the conventional surgical treatment group at 2 weeks postoperatively. Concerning olfaction, the sinus glucocorticoid stent group showed a significant reduction in scores at 12 weeks postoperatively, while the oral glucocorticoid group exhibited significant improvement starting from 8 weeks after surgery. There were no statistically significant differences in nasal congestion, rhinorrhea, facial pressure, and olfaction scores between the sinus glucocorticoid stent and oral glucocorticoid groups at 2, 4, 8, and 12 weeks postoperatively. Nasal endoscopy scores revealed lower polyp scores and edema at 2, 4, 8, and 12 weeks postoperatively for all three groups compared to preoperative scores. The conventional surgical treatment group exhibited a significant reduction in nasal secretion scores starting from 8 weeks after surgery, while both the sinus glucocorticoid stent and oral glucocorticoid groups showed significant reductions starting from 2 weeks postoperatively, with scores significantly lower than those of the conventional surgical treatment group at 2 weeks. Scab/scar scores in the conventional surgical treatment group significantly decreased from 8 weeks after surgery, while both the sinus glucocorticoid stent and oral glucocorticoid groups exhibited significant reductions starting from 4 weeks. No statistically significant differences were observed in endoscopy scores(including polyps, edema, nasal secretion, scars, and scabs) between the sinus glucocorticoid stent and oral glucocorticoid groups at 2, 4, 8, and 12 weeks postoperatively. Regarding adverse reactions, no postoperative complications related to sinus glucocorticoid stent were observed in the sinus glucocorticoid stent group. In the oral glucocorticoid group,1 patient experienced irritability, and 1 patient experienced weight gain. Conclusion:The glucocorticoid stent implantation has comparable effects to oral glucocorticoid in improving postoperative nasal symptoms, reducing nasal mucosal edema, scar formation, and nasal secretion in patients with CRSwNP undergoing FESS, with a better safety profile.

To analyze the trend of abnormal birth weight of full-term newborns and its correlation with parental reproductive age in Chongqing municipality from 2010 to 2022. Based on the Chongqing Birth Certificate System, full-term newborns born from January 2010 to December 2022 were selected. Parental information and birth weight were abstracted from the system. The joinpoint regression model was used to assess the trend of incidence of low birth weight (LBW) and macrosomia in the offspring from 2010 to 2022. The logistic regression model was utilized to analyze the association between parental reproduction age and birth weight of newborns. The average birth weight of 3 155 542 newborns was (3 305.8±410.5) g. The joinpoint regression model showed a decreasing trend for the incidence of LBW from 2010 to 2016 (APC=-4.26%, P<0.05), and an increasing trend from 2020 to 2022 (APC=8.99%, P<0.05). The incidence of macrosomia exhibited a decreasing trend from 2015 to 2022 (APC=-3.37%, P<0.05). The logistic regression model showed that, compared to the group with parents aged 20-34 years, the risk of LBW increased in other age groups. The risk of macrosomia decreased when either parent was aged<20 years, and increased when both parents were aged≥20 years. In conclusion, from 2010 to 2022, the incidence of LBW in full-term offspring in Chongqing municipality decreased first and then increased, and the incidence of macrosomia increased first and then decreased. Both young and advanced parental age were associated with an increased risk of LBW in offspring, and advanced parental age was also associated with an increased risk of macrosomia in offspring. Attention should be paid to the effects of advanced maternal and paternal age on offspring birth weight. Further efforts to control childbearing at a young age were needed.
