1.CHARACTERISTICS OF THE NEURONS RESPONDING TO ELECTRO-ACUPUNCTURE IN THE NUCLEUS RAPHE MAGNUS OF THE RAT
Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(04):-
A total of 100 neurons were recorded from the nucleus raphe magnus (NRM), of which 59 were identified as noxious-exaitation neurons; 30 as noxioes-inhibition neurons; 5 as non-noxious neurons; and 6 as non-responsive neurons Seventy neurons were further tested with electro-acupuncture (EA). 69.77% of the noxious-excitation neurons were excited and 68.42% of the noxious -inhibition neurons inhibited by EA. Stimulation of the periaqueductal gray (PAG) could activate the majority of the EA-response neurons. Systemic morphine could also affect the EA-response neurons through the following three patterns: excitation, inhibition and no-effect. No signilicant correlation between the response patterns of EA and morphine was found. The results indicate that the effect of NRM in EA and morphine analgesia is only partially overlapped.

Objective To investigate the expression of survivin/Human leukocyte antigen class I ( HLA-Ⅰ) proteins and its physiological significance in clear cell renal cell carcinoma ( CCRCC ) . Methods Immunohistochemistry was used to analyze survivin/HLA-Ⅰ protein expression in 90 cases of CCRCC and 10 normal tissues to study relationships with clinical symptoms and disease prognosis . Resutl s The level of survivin protein expression was found to be significantly higher in CCRCC tissues 82.2%( 74/90) than in normal tissues( 0/10).However, the relative amount of HLA-Ⅰprotein in colorectal cancer tis-sue was also found to be significantly lower 67.8%(61/90) than in normal tissues 90%(9/10).Survivin expression was associated with tumor grade , stage,and lymph node metastasis ( P=0.000, P=0.016, and P=0.001, respectively ) .Conversely , lost HLA-Ⅰexpression did not have any associations with clinicopath-ological data (P>0.05).Survivin negative patients (25.0%, 4/16) had a higher tumor-free survival rate than patients (52.7%, 39/74)with survivin expression (P=0.037).Patients (27.6%, 8/29) with normal HLA-Ⅰlevels had a higher tumor-free survival rate than those ( 60.7%, 37/61) with reduced HLA-Ⅰlev-els (P=0.020).The univariate and multivariate analyses indicated that expression of survivin and HLA indi -vidually and in combination were independent predictors for CCRCC patient survival . Conclusions Over-expression of survivin but reduced HLA-Ⅰ expression is associated with CCRCC development and progres-sion.

Ischemia reperfusion injury (IRI) of organs is a major challenge for clinicians, but the mechanism is still not elucidated, and the clinical treatment effect is still unsatisfactory. PARP-1-dependent cell death (parthanatos) is a non-apototic programmed cell death pathway involved in the development of the occurrence of IRI of organs. At the same time, parthanatos is also a multi-step pathway. There are many molecules in the parthanatos cascade that can be exploited to create therapeutic interventions for IRI, including PARP1, apoptosis inducing factor (AIF), and macrophage migration inhibitory factor (MIF). These critical molecules are involved in DNA damage, energy depletion and homeostasis imbalance. Therefore, these molecular signals in the parthanatos cascade represent promising therapeutic targets for the treatment of IRI. In the following, we will elaborate on the mechanisms and molecular characteristics of the parthanatos pathway and the relation between parthanatos pathway and IRI of vital organs. It aims to explore the posibility of IRI mechanism research and clinical treatment and to provide new ideas for clinicians and researchers.

Objective:To explore the predictive value of N-terminal-pro-B-type brain natriaretic peptide (NT-pro BNP) and B-type brain natriaretic peptide (BNP) of symptomatic patent ductus arteriosus (sPDA) in premature infants.Methods:Sixty premature infants were recruited. The gestational age was 26-32 weeks and the birth weight was less than 1 500 g. According to the echocardiography measured on the 3rd day, the infants were divided into PDA group (40 cases) and control group (20 cases). PDA group was divided into sPDA group (20 cases) and asPDA group (20 cases). The sPDA group was divided into treatment group (10 cases) and non-treatment group (10 cases). The asPDA group was further divided into self-closed group (10 cases) and non- self-closed group (10 cases). NT-pro BNP and BNP were examined on the 3rd and 7th day.Results:The level of NT-pro BNP among sPDA group, asPDA group and control group had significant difference on the 3rd and 7th day ( P<0.05). On the 7th day, the level of NT-pro BNP between treatment group and non-treatment group had significant difference [4 082(111 - 7 566) ng/L vs. 9 643 (2 362 - 25 000) ng/L, P<0.05] between self-closed group and non- self-closed group [603 (27 - 1 698) ng/L vs. 4 595 (896 - 9 873) ng/L, P<0.05]. The level of NT-pro BNP on the 3rd day was positively correlated with of ductus arteriosus diameter, ratio of left atrium diameter and aortic root diameter, ratio of ductus arteriosus diameter and left pulmonary artery diameter ( r=0.358 - 0.455, P<0.05). The area under the curve drawn by NT-pro BNP on the 3rd day was 0.783. Conclusions:The level of NT-pro BNP on the 3rd day can be used as a predictor of sPDA.

Objective:To observe the effect of esketamine on cardiac index in patients undergoing lumbar surgery in prone position under general anesthesia.Methods:Forty-five patients with prone lumbar surgery after general anesthesia in Hunan Provincial People′s Hospital from March to July 2021 were divided into observation group (24 cases, group A) and control group (21 cases, group B) according to random number table method. Group A received 0.5 mg/kg esketamine intravenously during induction, and 0.15 mg/(kg·h) esketamine intravenously for 2 h after prone position. Group B received the same amount of normal saline. Both groups were given sevoflurane and remifentanil during operation to maintain anesthesia, and sufentanil was given intermittently during operation. The mean arterial pressure (MAP), systolic blood pressure (SBP), diastolic pressure (DBP), cardiac index (CI), and heart rate (HR) before induction (T 0), during endotracheal intubation (T 1), 5 minutes after intubation (T 2), 5 minutes after prone position (T 3), 10 minutes after prone position (T 4), 30 minutes after prone position (T 5), 45 minutes after prone position (T 6), 60 minutes after prone position (T 7), 90 minutes after prone position (T 8), and 120 minutes after prone position (T 9) were recorded; The total dosage of norepinephrine 2 hours after anesthesia to prone position and extubation time after operation were also recorded. The Visual Analogue Scale (VAS) was performed 15 minutes after extubation, 6 and 24 hours after operation. Results:There was no significant difference in CI between T 3-T 9 and T 2 in group A ( P>0.05); the CI of group B at T 3-T 7 was significantly lower than that at T 2 (all P<0.05); there was no significant difference in CI between T 8-T 9 and T 2 in group B (all P>0.05); There was no significant difference in CI between group A and group B at T 0-T 2 (all P>0.05). The CI of group A at T 3-T 9 was significantly higher than that of group B (all P<0.05); The dosage of norepinephrine in group A was significantly lower than that in group B ( P<0.05); There was no significant difference in HR, MAP, SBP and DBP between the two groups at different time points (all P>0.05); there was also no significant difference in extubation time and VAS scores at 15 minutes, 6 hours and 24 hours after extubation between the two groups (all P>0.05). Conclusions:Intraoperative application of esketamine can increase CI after prone position and reduce the amount of norepinephrine during lumbar surgery.
