Objective:To evaluate the clinical effect of the position pillows for neuraxial anesthesia.Methods:This was a prospective randomized controlled trial. Four hundred and twelve patients regardless of gender, aged ≥18 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, who underwent elective surgery under neuraxial anesthesia at Peking University Third Hospital from February to October 2023, were selected and divided into 2 groups ( n=206 each) using a random number table method: pillow group (P group) and control group (C group). Group C underwent the conventional procedure for neuraxial anesthesia. The patients were placed in a position using the position pillow on the basis of oral education before routine anesthesia in group P. The success rate of puncture at first attempt, puncture time and position placement time were recorded. The adjustment of position, body movement and occurrence of discomfort during the puncture were also recorded. The visual analogue scale score was used to evaluate the level of anxiety before positioning, after positioning and after anesthesia. The visual analogue scale score was used to evaluate the patient′s comfort and the operator′s satisfaction with position after the anesthesia was completed. Results:Compared with group C, the time for positioning was significantly shortened, the anxiety level was decreased after positioning and after anesthesia, the rate of improvement in anxiety was increased, the scores for the patient′s comfort and the operator′s satisfaction with position were increased ( P<0.05), and no significant changes were found in the success rate of puncture at first attempt, puncture time and incidence of body movement during the puncture and incidence of the adjustment of position ( P>0.05). No discomfort was observed in either group during the puncture. Conclusions:This new type of position pillows for the neuraxial anesthesia can not only optimize the effect of position placement, but also improve the patients′ comfort.

OBJECTIVES: To explore the damage effects of chronic restraint stress (CRS) on amygdala cells through the rat CRS model. METHODS: The rat CRS model was established, and the changes in body weight and adrenal mass in control group and CRS group were monitored at 1 d, 7 d, 14 d and 21 d. The behavior changes were evaluated by the percentage of retention time of open arms and open arm entries using the elevated plus maze (EPM). ELISA was used to detect the concentrations of rat's corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH) and cortisol. The changes of expression of glucocorticoid receptor (GR) and glial fibrillary acidic protein (GFAP) in amygdala were determined by immunohistochemistry and Western blotting. Ultrastructure changes of glial cell were observed by transmission electron microscopy. The apoptosis rate of amygdala was measured by flow cytometry. RESULTS: Compared with the control group at the same time points, body weight of CRS 1 d, 7 d, 14 d and 21 d groups increased slowly, but adrenal mass increased significantly; the serum level of CRH, cortisol and ACTH increased significantly at 7 d, 14 d and 21 d respectively; the expression of GR in amygdala was increased while that of GFAP was decreased; EPM test suggested that the percentage of retention time of open arms and open arm entries decreased significantly after 14 d. The CRS group showed different degrees of glial cell damage in amygdala, and the apoptosis rate of glial cell was significantly increased in 21 d group. CONCLUSIONS This study successfully established a CRS model in rats, and anxiety-like behavioral changes in model rats may be caused by apoptosis of amygdala astrocytes.

Mitochondria are dynamic organelles that continuously divide and fuse. In recent years, in addition to the studies related to mitochondrial metabolism, the unique dynamics of mitochondria have gradually attracted researchers' attention. A growing body of research has revealed that mitochondrial dynamics are related to the biological behavior of tumor cells. Mitochondrial fission proteins (mitochondrial fission protein 1, FIS1) mediate the assembly of mitochondrial fission complexes and participate in the execution of mitochondrial fission. They are important proteins in the process of mitochondrial fusion and fission. However, few studies have revealed the expression and role of FIS1 in human cervical cancer. In this study, the expression level of FIS1 in human cervical cancer tissues and paracancer tissues were compared. The results showed that the level of FIS1 mRNA in human cervical cancer tissues was significantly lower than that in paracancer tissues (P<0. 01). Further KEGG pathway and GO Term-BP pathway analysis showed that the differential genes are mainly related to mitochondrial biological functions. Subsequently, HeLa cells with overexpressed FIS1 were investigated for their proliferation, migration, mitochondrial fission and ROS levels. The experimental results showed that FIS1 overexpression decreased HeLa cell proliferation and migration ability, enhanced mitochondrial fission and higher ROS levels. In conclusion, the expression of FIS1 in human cervical cancer cells was attenuated, while overexpression of FIS1 resulted in a series of abnormal biological functions in human cervical cancer cells. Further studies can be carried out to investigate the role of FIS1 in the treatment of human cervical cancer.

In recent years, the prevalence of chronic diseases among children in China has increased significantly, which has become an important public health problem affecting children's health.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Objective:To analyze the mean levels of skeletal muscle mass and strength in elderly patients with type 2 diabetes mellitus(T2DM), and to investigate the effects of chronic inflammatory factors and oxidative stress on them.Methods:A cross-sectional study was conducted on 120 patients with T2DM aged over 60 years and 126 elderly patients without diabetes(the control group). Skeletal muscle mass, strength and serum levels of chronic inflammatory factors interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)and 8-hydroxy-2′-deoxyguanosine(8-OHdG)were determined, and their effects on skeletal muscle mass and strength in elderly patients with T2DM were analyzed.Results:Compared with the control group, grip strength decreased in elderly patients with T2DM(25.03±7.85)kg vs.(29.52±7.73)kg( P<0.01), and skeletal muscle mass decreased(21.36±5.46)kg vs.(22.01±5.22)kg with no significant difference( P>0.05). Serum levels of 8-OHdG were higher in elderly patients with T2DM than in the control group(3.08±0.26)ng/L vs.(2.59±0.16)ng/L( P<0.01). Correlation and regression analysis results showed that 8-OHdG was an influencing factor for muscle strength in elderly patients with T2DM( R2=0.457)and that height and weight could be influencing factors for skeletal muscle mass in elderly patients with T2DM( R2=0.822). Conclusions:Skeletal muscle mass and strength decline in elderly T2DM patients, probably as a result of increased levels of oxidative stress.These findings may serve as evidence for sarcopenia intervention in elderly T2DM patients.

Objective To investigate the clinical features of patients with heart failure and the safety and efficacy of noninvasive ventilator in patients with heart failure.Methods Sequentially enrolled 65 patients who were diagnosed with decompensated heart failure in Tianjin Chest Hospital Heart Center from October 2016 to October 2017 and who had acute heart failure during hospitalization requiring noninvasive ventilator,were divided into the HF-PEF group (n=19) and HF-REF group (n=46).The clinical data of the two groups and the observation indexes before and after the application of the non-invasive ventilator were compared.Results Comparing the admission data of the two groups,the proportion of patients with hypertension (57.9％ vs 21.7％,P=0.005) and LVEF(％) (53.00±4.85 vs 33.07±7.24,P＜0.01)were significantly higher in the HF-PEF group than those in the HF-REF group;LVEDD (mm) in the HFPEF group was significantly lower than that in the HF-REF group (50.00±5.23 vs 63.82±8.95,P＜0.01).In the two groups of patients with acute left heart failure,blood lactate levels (mmol/L) in the HF-PEF group (4.20±1.06 vs 2.02±0.88,P＜0.05) and systolic blood pressure (mmHg) (151.32±43.40 vs 117.90± 19.55,P＜0.05) were significantly higher than those in the HF-REF group.After the application of non-invasive ventilator,systolic blood pressure (mmHg) (34.38±9.36 vs 16.94±5.19,P=0.038) and PaCO2 (mmHg)(2.49±0.98 vs-0.06±0.00,P=0.025),and lactic acid (mmol/L) (2.06±0.67 vs 0.04±0.01,P=0.001) were significantly lower in the HF-PEF group than those in the HF-REF group.While the NT-proBNP level (ng/L) (13 064.90±1 963.83 vs 11 687.13±1 028.03,P=0.848) did not decrease significantly,and the time of non-invasive ventilator application (h)was significantly longer than that in the HF-REF group (152.74±10.61 vs 71.03±10.41,P=0.013).Conclusions Hypertension is the main cause of HF-PEF group.The systolic blood pressure and blood lactate level in HF-PEF patients with acute left heart failure are significantly higher than HF-REF patients.Non-invasive ventilator is also safe and effective for the treatment of acute left heart failure in HF-PEF patients,but HF-PEF patients with acute left heart failure have a longer clinical remission time.

Objective To observe the clinical efficacy of intradermal needle plus acupoint application with Da Huang (Radix et Rhizoma Rhei) in preventing constipation after craniocerebral injury. Method Two hundred patients with acute craniocerebral injury were randomized into a treatment group and a control group, 100 cases each. The control group received conventional nursing care to prevent constipation, while the treatment group was additionally treated with intradermal needle plus acupoint application with Da Huang (Radix et Rhizoma Rhei). The occurrence of constipation within a week was observed in the two groups. Result The occurrence rate of constipation was 12.0％ in the treatment group versus 32.0％ in the control group, and the between-group difference was statistically significant (P<0.05). Conclusion Intradermal needle plus acupoint application can effectively reduce the frequency of constipation in patients with acute craniocerebral injury.

OBJECTIVETo compare the short-term outcomes between robotic and laparoscopic radical total gastrectomy in gastric cancer patients with BMI index ≥24 kg/m.

METHODClinical data of 93 gastric cancer patients who underwent robotic and laparoscopic radical total gastrectomy at PLA General Hospital from April 2016 to April 2017 were retrospectively analyzed. The retrospective cohort study was adopted.

INCLUSION CRITERIApreoperatively definite diagnosis of primary gastric cancer by endoscopy and biopsy; preoperative BMI ≥24 kg/m; no previous abdominal surgery; no previous chemotherapy and radiotherapy; no distant metastasis or invasion into adjacent organs before operation or during operation; receiving radical gastrectomy; Roux-en-Y reconstruction of digestive tract in open procedure. According to approaches of minimally invasive surgery, 24 patients underwent robotic surgery and 69 underwent laparoscopic surgery. The intraoperative parameters (overall operative time, pneumoperitoneal time, open procedure time, intraoperative blood loss, transfusion rate, number of total retrieved lymph nodes and metastatic lymph nodes) and postoperative parameters (drainage in the first postoperative day, the first defecation time, morbidity of postoperative complication and hospital stay) were compared between two groups. Correlation of the above parameters were analyzed.

RESULTSOf 93 patients, 77 were male and 16 female with an average age of (60.0±10.6) years. The average BMI was (26.8±1.3) kg/m in whole patients, (26.9±1.6) kg/m in robotic group and (26.8±1.7) kg/m in laparoscopic group. No significant differences in age, gender, BMI, preoperative ASA class, postoperative pathological findings and clinical classification were observed between two groups, which made short-term parameters between two groups comparable. The robotic group had a significantly longer overall operative time [(301.2±68.9) minutes vs. (247.3±59.6) minutes, P=0.000], longer open procedure time [(141.5±26.3) minutes vs. (92.5±36.7) minutes, P=0.029] and higher cost than laparoscopy group[(17.5×10 ± 9.7×10) yuan vs. (10.0×10 ± 2.3×10) yuan, P=0.001]. Pneumoperitoneal operative time, intraoperative blood loss, transfusion rate, number of total retrieved lymph nodes, number of harvested metastatic lymph nodes and postoperative short-term efficacy were similar between the two groups (all P>0.05). In robotic group, pneumoperitoneal operative time was positively correlated with overall operative time (r=0.708, P=0.010); total cost was positively correlated with postoperative hospital stay (r=0.493, P=0.000) and open procedure time was negatively correlated with the first defecation time (r=-0.962, P=0.038). In laparoscopy group, total cost was positively correlated with overall operative time (r=0.411, P=0.046), drainage volume in the first postoperative day was positively correlated with the number of total dissected lymph node (r=0.540, P=0.006), postoperative hospital stay was positively correlated with intraoperative blood loss (r=0.574, P=0.003), total cost was positively correlated with intraoperative blood loss and hospital stay (r=0.609, P=0.002; r=0.865, P=0.000), drainage volume in the first postoperative day was positively correlated with BMI (r=0.533, P=0.007).

CONCLUSIONFor gastric cancer patients with BMI ≥24 kg/m, robotic radical total gastrectomy is associated with longer operative time and higher cost, but is less vulnerable to the change of BMI and more in favor of the realization of enhanced recovery after surgery (ERAS) than laparoscopic radical total gastectomy.
