Objective To investigate the correlation between thyroid function,neutrophil/lymphocyte ratio(NLR),platelet/lymphocyte ratio(PLR)and diabetic ketoacidosis(DKA).Methods A total of 272 diabetic patients admitted to the Department of Endocrinology,Anhui No.2 Provincial People's Hospital were enrolled in this study from January 2021 to March 2024 and divided into DKA group(n=74),diabetic ketosis group(DK group,n=100)and simple DM group(n=98)according to their disease conditions.Serum free triiodothyronine(FT3),free tetraiodothyronine(FT4),thyroid stimulating hormone(TSH),FPG,HbA1c,anion gap(AG),white blood cells(WBC),neutrophils(N),platelets(PLT)and lymphocytes(L)were detected in each group,and NLR and PLR were calculated.The influence factors of DKA were analyzed by logistic regression,and the diagnostic value of FT3,NLR and PLR in DKA was evaluated by receiver operating characteristic(ROC)curve.Results Hospitalization days,FPG,HbA1c,incidence of LT3S,AG,WBC,N,PLT,NLR,PLR were higher in DKA group than in DM and DK groups(P<0.05),Age,FT3,FT4,TSH,L were lower in DKA group than in DM and DK groups(P<0.05).Logistic regression analysis showed that FT3,AG,NLR and PLR were the influencing factors for DKA.ROC curve showed that the area under the curve of FT3,NLR,PLR and combined detection to predict DKA were 0.961,0.938,0.810 and 0.980,the sensitivity was 87.8%,90.5%,75.7%and 98.6%,the specificity was 95.5%,92.9%,76.3%,92.4%,and the combined detection was superior to the single detection.Conclusions FT3,NLR,PLR have a certain diagnostic value for DKA,and the combined detection of the three has a high diagnostic value,which can provide a reference for clinical diagnosis of DKA.

BACKGROUND:The maximum muscle strength is typically used for evaluating the recovery of muscle function after anterior cruciate ligament reconstruction.Recent studies have suggested that neuromuscular function should also be considered,such as rate of force development,which measures the slope of the force time curve at different time intervals under conditions of isometric muscle contraction. OBJECTIVE:To elaborate on the current research status and shortcomings of muscle isometric rate of force development in patients undergoing anterior cruciate ligament reconstruction surgery,and analyze the degree of defects in quadriceps femoris and hamstring isometric rate of force development at different times after surgery;to analyze the effect of isometric rate of force development on postoperative functional performance,thereby providing important information for optimizing postoperative rehabilitation following anterior cruciate ligament reconstruction,reducing secondary injury to patients,and reducing the incidence of knee osteoarthritis. METHODS:Literature retrieval of CNKI,VIP,WanFang and PubMed was performed using"anterior cruciate ligament,rate of force development"as Chinese search terms and"anterior cruciate ligament,rate of force development,rate of torque development"as English search terms.Finally,69 articles were included according to inclusion and exclusion criteria. RESULTS AND CONCLUSION:Most studies have found defects in bilateral muscle isometric rate of force development in patients undergoing anterior cruciate ligament reconstruction within 6 months.Early isometric rate of force development of the bilateral hamstring muscles(i.e.the slope of the force time curve at any time interval during muscle contraction of 100 ms)showed significant improvement after 6 months.However,long-term defects in early isometric rate of force development of the bilateral quadriceps indicate long-term damage to the neuromuscular function of the quadriceps after surgery.There is limited research on late isometric rate of force development(the slope of the force time curve at any time interval after 100 ms of muscle contraction),and conclusions cannot be drawn.Regarding landing exercises(jumping to the ground,lateral cutting,etc.)and daily activities(walking,running),early isometric rate of force development of the quadriceps is more correlated with isometric peak torque.Abnormal biomechanical changes during exercise are considered an important risk factor for secondary injury and traumatic knee osteoarthritis in patients.Actively improving early isometric rate of force development of the quadriceps may reduce the incidence of secondary injury and traumatic knee osteoarthritis.Currently,there is limited evidence to suggest that whole-body vibration training can improve early isometric rate of force development of the quadriceps femoris in patients undergoing anterior cruciate ligament reconstruction.It is recommended to use neuromuscular electrical stimulation to intervene in the quadriceps and hamstring in the early postoperative stage and implement explosive force and high resistance training in the late postoperative stage,which may improve the isometric rate of force development in patients.Generating sufficient muscle strength in a short period of time is necessary to effectively protect the anterior cruciate ligament,while the relationship between isometric rate of force development in the hamstring muscle and functional performance is still unclear,which may provide information on preventing secondary injury in patients.It is recommended to use the isometric rate of force development as one of the evaluation indicators for guiding rehabilitation and restoring movement.In addition to focusing on improving symmetry and differences from normal individuals,the hamstring to quadriceps strength ratio should also be considered.An appropriate range of ratios can ensure the balance of muscles during rapid muscle exertion,which may reduce the occurrence of secondary injuries.However,the normal range of ratios is not yet clear.Future research should consider the effects of graft type and knee flexion angle on isometric rate of force development,in order to identify neuromuscular dysfunction in patients as much as possible and help them recover better.

Whole-course nutrition management embodies a systematic, dynamic, and individualized approach to precise nutrition management, which could potentially improve patient outcomes. Artificial intelligence has seen advances in the application in medical settings, including nutrition, and its disruptive technology enables the optimization of nutrition management. The nutrition management modality augmented by artificial intelligence to some extent meets the need of comprehensive, dynamic, individualized, and precise nutrition management throughout the whole continuum. It not only facilitates nutrition screening and evaluation, nutritional diagnosis, and individualized treatment regimens, but also allows nutritional monitoring and corresponding dynamic adjustments for optimal nutritional treatment, to improve clinical outcomes. Our aim is to investigate the application and significance of artificial intelligence in the whole-course nutrition management.

Objective:To evaluate the effect of esketamine on postoperative acute lung injury (ALI) in pediatric patients undergoing living donor liver transplantation.Methods:Sixty pediatric patients of either sex with biliary atresia, aged 0-36 months, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, with cardiac function grade I or Ⅱ, with Child-Pugh grade B or C, undergoing living donor liver transplantation, were divided into 2 groups ( n=30 each) using a computer-generated table of random numbers: control group (group C) and esketamine group (group S). Combined intravenous-inhalational anesthesia was performed with propofol and sevoflurane in both groups, and in addition esketamine was intravenously infused continuously after induction in group S. After anesthesia induction (T 0), at 60 min after start of surgery (T 1), at 10 min after anhepatic phase (T 2), at 60 min after portal vein opening (T 3), and immediately after abdominal closure (T 4), central venous blood samples were collected for determination of the serum concentrations of Clara cell secretory protein 16, surface active protein D, soluble receptor for advanced glycation end-products, high mobility group protein B1, interleukin-1beta and tumor necrosis factor-alpha (using enzyme-linked immunosorbent assay), concentrations of malondialdehyde (using TBA method), and activity of superoxide dismutase (using hydroxylamine method). The dynamic lung compliance was recorded from T 0 to T 4. Blood samples were taken from the radial artery at T 0 and 24 h after surgery (T 5) for blood gas analysis, and oxygenation index and respiratory index were calculated. Lung ultrasound scores were recorded at 24 h before surgery and T 5. The postoperative mechanical ventilation time and duration of intensive care unit stay were recorded. The occurrence of ALI within 7 days after liver transplantation was observed. Results:Compared with group C, the serum concentrations of Clara cell secretory protein 16, surface active protein D, soluble receptor for advanced glycation end products, high mobility group protein B1, interleukin-1beta, tumor necrosis factor-alpha and malondialdehyde were significantly decreased, and the activity of superoxide dismutase was increased at T 3, 4, the oxygenation index was increased and respiratory index was decreased at T 3-T 5, lung ultrasound C score and B score were decreased at T 5, the postoperative mechanical ventilation time and duration of intensive care unit stay were shortened, and the incidence of ALI was decreased in group S ( P<0.05). Conclusions:Esketamine can alleviate postoperative ALI in pediatric patients undergoing living donor liver transplantation.

Objective:To compare the effects of different anesthesia methods on perioperative lung injury in pediatric patients with biliary atresia undergoing living donor liver transplantation.Methods:Ninety-one American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ pediatric patients with biliary atresia, regardless of gender, aged 0-36 months, with cardiac function grade of Ⅰ or Ⅱ and Child-Pugh grade of B or C, undergoing elective living donor liver transplantation, were selected. According to the anesthesia method, the pediatric patients were divided into 3 groups: propofol-based anesthesia group (P group, n=30), sevoflurane-based anesthesia group (S group, n=30) and propofol-sevoflurane-based anesthesia group (PS group, n=31). Group P received intravenous infusion of 1% propofol 9-15 mg·kg -1·h -1. In group S, sevoflurane was inhaled and the end-tidal concentration was maintained at 2.6%-4.0%.In PS group, 1% propofol 9-15 mg·kg -1·h -1 was intravenously infused and sevoflurane was inhaled, maintaining an end-tidal concentration at 1.0%-2.5%. Remifentanil 0.1-1.0 μg·kg -1·min -1 was intravenously infused during operation for analgesia, and cisatracurium besylate 1-2 μg·kg -1·min -1 was intravenously infused to maintain muscle relaxation in three groups. Immediately after anesthesia induction (T 0), at 60 min after start of surgery (T 1), at 10 min of anhepatic phase (T 2), at 60 min after portal vein opening (T 3), and immediately after abdominal closure (T 4), the concentrations of serum Clara cell secretory protein 16 (CC16), surfactant protein (SP-D), soluble receptors for advanced glycation end products (s-RAGE), high mobility group protein B1 (HMGB1), tumor necrosis factor-alpha (TNF-α) and interleukin-1beta (IL-1β) were measured using enzyme-linked immunosorbent assay method, and lung compliance (Cdyn) was simultaneously recorded. At T 0-T 4 and 24 h after surgery (T 5), the arterial blood gas analysis was performed to calculate the oxygenation index (OI) and respiratory index (RI). Lung ultrasound scores (LUS scores) were assessed at 24 h before surgery and T 5. The occurrence of pulmonary complications was recorded within 7 days after surgery. The survival was observed for 6 months after surgery. Results:There were no statistically significant differences in serum concentrations of CC16, SP-D and s-RAGE concentrations and LUS scores at different time points between group S and group P ( P>0.05). Compared with S group and P group, the serum CC16 concentrations at T 3 and s-RAGE concentrations at T 3, 4 were significantly decreased, and the C and B scores were decreased at T 5 in PS group ( P<0.05). There were no statistically significant differences in the concentrations of serum HMGB1, IL-1β and TNF-α, Cydn and incidence of ALI/ARDS, pulmonary infection, pleural effusion, and atelectasis within 7 days after surgery among the three groups( P>0.05). The 6-month survival rate was 100% in the three groups. Conclusions:Propofol-sevoflurane-based anesthesia has a better efficacy in reducing perioperative lung injury than propofol-based anesthesia and sevoflurane-based anesthesia in the perioperative period of liver transplantation.

Objective:To study the correlation between nutritional status and length of hospital stay in patients with digestive disorders.Methods:The data were collected from the database of a multi-center investigation on the dynamic changes of nutritional status of hospitalized patients in China, a project led by the Geriatric Nutrition Support Group, Society of Parenteral and Enteral Nutrition, Chinese Medical Association. The enrolled patients were screened for malnutrition and possible sarcopenia using Global Leadership Initiative on Malnutrition criteria, and the dynamic changes of serum biochemical indexes during hospital stay and the effects of malnutrition and possible sarcopenia on the length and cost of hospital stay were analyzed.Results:A total of 1 180 patients were enrolled, with an average age of (56.3±16.1) years, the average height of (164.65±8.29) cm, and the average weight of (62.12±12.12) kg. There were significant differences in body weight, body mass index, calf circumference, lymphocyte count, triglyceride, hemoglobin, albumin and total protein between at discharge and at admission ( P<0.001). There might be a correlation between post-admission malnutrition and sarcopenia. There was neither significant difference in the proportion of patients with malnutrition at admission among different age groups ( P=0.438), nor in that at discharge among different age groups ( P=0.439). The proportion of patients with malnutrition showed no significant difference between subgroups with patients<65 years old and ≥ 65 years old, at admission and discharge ( P>0.05). However, comparison of the proportion of patients with sarcopenia between subgroups with patients<65 years old and ≥65 years old displayed significant differences at admission and discharge ( P<0.001), but not the comparison of the proportion of patients with possible sarcopenia ( P>0.05). The length of hospital stay in patients with malnutrition was significantly longer than that in patients without malnutrition [(13.22±6.24) days vs. (12.08±5.25) days, P<0.001]. The length of hospital stay of patients with and without sarcopenia was also significantly different [(12.87±5.93) days vs. (12.02±5.22) days, P<0.001). Patients with concurrent malnutrition and sarcopenia had longer hospital stay [(14.57±7.15) days vs. (12.07±5.22) days, P<0.001], and higher medical cost [(2.78±2.19) ten thousand Chinese Yuan vs. (2.24±2.33) ten thousand Chinese Yuan, P<0.05)] compared with those without concurrent malnutrition and sarcopenia. Conclusions:A large proportion of patients with digestive disorders were diagnosed with malnutrition and/or possible sarcopenia during hospitalization. There is possible correlation between malnutrition and possible sarcopenia, and both can lead to a longer hospital stay and higher medical cost.

Micronutrients (MNs), including vitamins and trace elements, play an indispensable role in human metabolism, immune function and other aspects. Due to the chronic microinflammation and long-term chemoradiotherapy, patients with malignant tumors often suffer from malnutrition, resulting in different degrees of MNs deficiency. In severe cases, MNs deficiency is closely related to the adverse clinical outcomes. Therefore, reasonable MNs supplementation is of great significance in improving the prognosis and quality of life of patients with tumors. Recently, multiple guidelines have made recommendations on the application of MN supplementation in various clinical settings, providing evidence for the standardized MN supplementation in patients with malignant tumors.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of a child with multiple pterygium syndrome (MPS). METHODS: A child with MPS who was treated at the Orthopedics Department of Guangzhou Women and Children's Medical Center Affiliated to Guangzhou Medical University on August 19, 2020 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples of the child and her parents were also collected. Whole exome sequencing (WES) was carried out for the child. Candidate variant was validated by Sanger sequencing of her parents and bioinformatic analysis. RESULTS: The child, an 11-year-old female, had a complain of "scoliosis found 8 years before and aggravated with unequal shoulder height for 1 year". WES results revealed that she has carried a homozygous c.55+1G>C splice variant of the CHRNG gene, for which both of her parents were heterozygous carriers. By bioinformatic analysis, the c.55+1G>C variant has not been recorded by the CNKI, Wanfang data knowledge service platform and HGMG databases. Analysis with Multain online software suggested that the amino acid encoded by this site is highly conserved among various species. As predicted with the CRYP-SKIP online software, the probability of activation and skipping of the potential splice site in exon 1 caused by this variant is 0.30 and 0.70, respectively. The child was diagnosed with MPS. CONCLUSION The CHRNG gene c.55+1G>C variant probably underlay the MPS in this patient.

Most hospitalized patients infected with coronavirus disease 2019 (COVID-19) are in severe or critical condition, and malnutrition is a key factor contributing to adverse outcomes. The basic principles of medical nutrition therapy have been determined in the recently released tenth edition of the National Diagnosis and Treatment Protocol. The principles have promoted nutritional risk assessment, emphasized the preferred method of enteral nutrition, and recommended the daily intake of calories at 25 to 30 kcal/kg and protein at > 1.2g/kg. Parenteral nutrition should be also added when necessary. Based on the above principles, Beijing Hospital has refined the medical nutrition therapy measures to facilitate the implementation in clinical practice, in order to improve healthcare quality and decrease the mortality in COVID-19 patients.

Objective:To study the association of frailty status with nutritional risk and the effect on clinical outcomes among elderly surgical inpatients.Methods:Elderly inpatients from the surgery department of Beijing Hospital were enrolled from January to June 2021. Frail scale and nutritional risk screening 2002 (NRS 2002) were used for frailty evaluation and nutrition risk screening. The influence of frailty and associated nutrition risk in elderly surgical inpatients was analyzed.Results:487 elderly surgical patients were included, of whom 131 cases were in the non-frailty group, 279 cases were in the pre-frailty group and 77 cases were in the frailty group, according to the Frail scale score. 146 cases were at nutritional risk, of whom 8 (6.1% of 131) were in the non-frailty group, 87 (31.2% of 279) in the pre-frailty group and 51 (66.2% of 77) were in the frailty group. According to univariate/multivariate logistic regression analysis of frailty in elderly surgical patients, a higher NRS 2002 score, older age, and the presence of multiple concurrent diseases (≥ 5) were significantly associated with frailty ( P < 0.001). The Frail scale score was positively correlated with NRS 2002 score ( r = 0.448, P < 0.01). Multiple comparisons showed that frailty had statistically significant effects on hospital stay and medical costs in elderly surgical patients ( P < 0.05). Conclusions:The prevalence of frailty is higher in elderly surgical patients, and the prevalence of nutritional risk increases with the progression of frailty. Frailty can lead to prolonged hospital stays and increased hospital costs in elderly surgical patients.
