Objective:To investigate the effects of three different anesthetic techniques on pere-anesthesia circulation,stree response and post-anesthesia recovery in patients undergoing leparoscopic cholecystectomy(LC).Methods:Sixty-six ASA Ⅰ or Ⅱ patients aged 18 to 60 undergoing selected LC surgery were randomly divied into 3 groups(n=22).The patients in group I were induced and maintained with remifentanil and sevoflurane.The patients in group Ⅱ with fentanil,propofol and isoflurane,while the patients in group Ⅲ with remifentanil and propofol TCI.MAP and HR were measured before induction,before intubation,at 5 min after intubation,1 min and 15 min after the establishmen of CO2 pneumoperitoneum and at the end of operation.Blood cortisol(Cor)and blood glucose(Glu)were measured before induction,after induction 5 min and at the end of operation;Blood interleukin-6(IL-6)was measured before induction and at the end of operation.Postoperative recovery time,Alddret ≥9,the rate of PONV and VAS score were measured on the first postoperative day.Results:There were significant decreases of MAP in group Ⅰ and Ⅱ before intubation(P 0.05).Conclusion:The three anesthetic techniques can be used safely on LC operation,anesthesia with remifentanil and sevoflurane,anesthesia with remifentanil and propofol TCI have shorter post-operative recovery time and high quality compared with the anesthesia with fentanil,isoflurane and propofol.LC operation can cause obvious stress response of the body,significant postoperative pain and high rate of PONV,which should be actively dealt with.

Abstract: Objective　To explore the accurate diagnosis of children with suspected rare inherited metabolic diseases, and to compare the application value of mass spectrometry and genetic testing in the diagnosis of rare inherited metabolic diseases (IMD). Methods　The clinical information, mass spectrometry, and genetic results of children with suspected rare inherited metabolic diseases admitted to the Department of Pediatrics, the Affiliated Haikou Hospital of Xiangya Medical College, Central South University from March 2017 to December 2021 were analyzed retrospectively. Results　156 children with suspected rare inherited metabolic diseases were detected by mass spectrometry, 67 cases were positive and 89 cases were negative. Children with positive initial examination were retested, and 19 cases were positive. Among the retest positive cases, 13 cases were given genetic testing, and 9 cases were positive and 4 cases were negative. Among the initial negative cases, 54 children with poor therapeutic effect and high clinical suspicion of inherited metabolic diseases completed genetic testing, 15 cases were positive and 39 cases were negative. The results of the two detection methods were compared, the positive rate of mass spectrometry was 19.4%(13/67), and the positive rate of genetic testing was 35.8%(24/67). The continuity correction of Pearson's chi-square test of continuity correction suggested that the results of genetic testing and mass spectrometry were different, and the difference was statistically significant (P<0.05). Taking genetic testing as the gold standard, the sensitivity and specificity of mass spectrometry detection were 37.5% (95%CI:19.6%-59.2%) and 90.7% (95%CI:76.9%-97.0%), respectively. Among the 24 confirmed cases, 5 cases were diagnosed by gene panel and 19 cases were diagnosed by whole exome sequencing (WES). One case diagnosed by WES had no pathogenic mutation detected by gene panel before diagnosis. The detection of DNM1L gene c.1040C>G and AMN gene c.651+1G>C are novel pathogenic gene variants, which have clinical significance. Conclusions　The ability of mass spectrometry in the diagnosis of inherited metabolic diseases is limited. Genetic testing, especially whole exome sequencing, can be the first choice for individualized diagnosis of suspected rare inherited metabolic diseases. In addition, the new mutation sites found by WES in this study enriched the pathogenic gene mutation spectrum and provided direction for further functional biological experiments.

Experiments were carried on cultured neonatal myocardial cells of rat to study the effects of angiotensin Ⅰ(AngⅠ) and Ⅱ (AngⅡ) on the synthesis of DNA, RNA, protein and on the cardiac hypertrophy. It was shown that the incorporation of both ~3H-TdR and ~(14)C-uR increased over a set of time periods after addition of AngⅠ and AngⅡ to the medium. The mean protein content of the single myocardial cell was also enhanced, and the volume of myocardial cell was increased significantly after a continuous stimulation of AngⅠ and AngⅡ for 7 days. No stimulation effect was observed either in the synthesis of DNA, RNA, and protein or in the volume of myocardial cells after addition of AngⅠ together with the angiotensin converting enzyme inhibitor(ACEI, captopril). These results indicated that: (1). AngⅠ acts as a regulator by its indirect stimulation effect on the synthesis of DNA, RNA and protein of myocardial cells, since it must be changed into AngⅡ by the ACE present in myocardial cells. The ACE can be inhibited by the ACEI: (2) The hypertrophy of cultured neonatal myocardial cells may induced by a continuous stimulation of AngⅠ and AngⅡ.

PGF2. What we observsd suggests that PGE2 has the ability to inhibit the decidual cells directly; neither the contraction of the uterus nor the metabolism of estrogen or progestogen may be responsible for this effect. This inhibitory effect of PGE2 on decidual cells may be one of the mechanisms for the termination of the early pregnancy.
