Chinese Journal of Interventional Cardiology 2003;0(05):-
Objective To evaluate the prognosis capacity of the Primary Angioplasty in Myocardial Infarction (PAMI) risk score for 6 months mortality in the clinical patients with ST segment elevation myocardial infarction treated with primary percutaneous coronary intervention (PCI), in addition to asses the incremental value of EF and multivessel disease for risk stratification. Methods Six clinical variables and their relative value of score derived from PAMI risk scoring system were used to determine individual's risk score. The patients with STEMI were evaluated during the in-hospital period and followed-up for a mean of (10.34?3.24) months for mortality. The p values were calculated using a Kruskal-Wallis H test for categorical variables when appropriate; otherwise Independent-samples test was used. Logistic regression examined the discriminant accuracy of the PAMI risk score to predict death and assessed the incremental value of the EF and multivessel disease. Results A 88.8% of patients (183 patients) finished the follow up of 6 months. The overall in-hospital mortality rate was 4.4%, 30-day mortality rate was 6% and 6 months mortality rate was 9.3%. Eighty-eight patients scored 0-2 points, 54 patients scored 3-5 points, 17 patients scored 6-8 points and 24 patients scored ≥9 points. The 6 months mortality were 1.1%,3.7%, 17.6% and 41.7% respectively. Logistic regression analysis indicated that multivessel disease is a risk factor (OR 10.189) and EF is a protected factor (OR 0.849) for 6 months mortality after PCI. Multivessel disease and EF provided incremental information over that provided by the PAMI risk score. Conclusion The PAMI risk score can be applied in early stage after PCI for mortality risk assessment for patients with STEMI. EF and multivessel disease also convey important prognostic information and should be included in risk stratification after STEMI.

Objective To determine the proper dosage of fentanyl for open heart surgery performed under cardiopulmonary bypass (CPB) without aortic cross-clamping and cardioplegia.Methods Twenty-seven ASA Ⅰ -H patients (10 male, 17 female) with fairly good cardiac function (NYHA Ⅰ - Ⅱ) scheduled for surgical repair of atrioseptal defect ( ASD) or ventricular septal defect (VSD) or mitral valve replacement (MVR) were studied. Age ranged from 18 to 44 years and body weight from 35 to 58 kg. The patients were randomly divided into three fentanyl dosage groups: group Ⅰ 10?kg ; group II 30 ?g kg-1 and group Ⅲ 50 ?g kg-1. Premedication consisted of intramuscular pethidine 1-2 mg kg-1 and scopolamine 0.05-0.06 mg kg-1 . Anesthesia was induced with midazolam 0.2 mg kg-1 and fentanyl 5 ?g kg-1 . Tracheal intubation was facilitated with vecuronium 0.15 mg g-1 . The patients were mechanically ventilated (Vr 8-10 ml kg-1 ,F 10-12 bpm,FiO2 100% ). The rest of the total dose of fentanyl (5 ?g kg-1 in group I , 25 ?g kg-1 in group II , 45 ?g kg-1 in group III) was infused after induction of anesthesia until the initiation of CPB, supplemented with inhalation of 0.6 % isoflurane. During CPB propofol was infused at 5 mg kg-1 h-1 . after discontinuation of CPB, again 0.6% isoflurane was inhaled until the end of surgery. Vecuronium 0.05 mg kg was given every 25-30 min during operation. EGG, HR, BP, CVP, SpO2, PET CO2 and body temperature (naso-pharyngeal and rectal) were continuously monitored during operation. Arterial blood samples were obtained before anesthesia (T0), 5 min after tracheal intubation (T, ) , immediately after thoracotomy (T2) , immediately before CPB (T3), 15 min after CPB was initiated (T4) , 10 min after termination of CPB (T5) and 5 min after chest was closed (T6) for blood gas analyses and determination of blood electrolytes and acid-base balance and blood concentrations of glucose, ACTH, angiotensin Ⅱ (A- Ⅱ ) and cortisol. Time of emergence from anesthesia and extubation were recorded.Results The demographic data, including age and body weight, CPB time and duration of surgery were comparable among the three groups. There were no significant changes in SpO2 , PETCO2 , body temperature, blood gases and electrolytes during operation in the three groups. MAP decreased significantly during CPB. The blood glucose, ACTH, A- Ⅱ and cortisol concentrations increased significantly during and after CPB as compared with the preanesthetic baseline (T0 ) ( P

Objective:To explore the predictive factors for adverse clinical outcomes in critically ill adult patients with autoimmune encephalitis by analyzing their clinical characteristics and prognosis.Methods:Clinical data of patients diagnosed with " confirmed" or " possible" autoimmune encephalitis who were hospitalized in the intensive care unit (ICU) of the Department of Neurology at the Second Xiangya Hospital of Central South University from January 2015 to December 2023 were retrospectively collected. The neurological function of patients at 3, 6, and 12 months of onset was followed up, and the modified Rankin Scale (mRS) at 12 months was used as an evaluation index for clinical prognosis; Further analysis was conducted on the relationship between clinical features, auxiliary examinations, and prognosis.Results:The 12-month survival rate of critically ill adult patients with autoimmune encephalitis in our center was 90.7%(117/129), and the 6-month poor prognosis rate was 28.7%(37/129). Univariate logistic regression analysis found that age of onset ( P<0.01), presence of tumors ( P<0.01), mechanical ventilation ( P<0.01), Glasgow Coma Scale (GCS) at ICU admission ( P<0.01), Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score ( P<0.01), cerebrospinal fluid glucose ( P<0.01), cerebrospinal fluid protein level ( P=0.02), epileptic waves in electroencephalography (EEG) ( P=0.03), use of glucocorticoids ( P=0.04), and time interval between initiation of intravenous immunoglobulin (IVIG) and onset ( P=0.04) were associated with prognosis. The results of multiple logistic regression analysis showed that mechanical ventilation [ P=0.01, area under the curve (AUC)=0.72)], APACHE Ⅱ score ( P=0.04, AUC=0.68), cerebrospinal fluid protein content ( P=0.04, AUC=0.65), and the time interval between initiation of IVIG and onset ( P=0.02, AUC=0.64) were independent predictive factors for the prognosis of adult critical autoimmune encephalitis. The prognostic prediction model for adult critical autoimmune encephalitis established by combining these four indicators has a higher AUC (0.85). Conclusions:Mechanical ventilation, APACHE Ⅱ score, cerebrospinal fluid protein level, and the time interval between initiation of IVIG and onset are predictive factors for poor clinical outcomes in critically ill autoimmune encephalitis in adults; The prognostic prediction model for adult critical autoimmune encephalitis established by combining these four indicators can identify patients with poor prognosis early, which is beneficial for early comprehensive management and intervention treatment to improve patient prognosis.

Dystonia is a movement disorder characterized by involuntary abnormal movements or postures due to sustained or intermittent muscle contractions. In recent years, rapid progress has been achieved in the genetics of this disease, leading to an in-depth understanding of common genes and phenotypes related to dystonia. GNAO1 is one of the genes closely associated with dystonia. GNAO1 gene, nevertheless, remains largely unknown to most clinicians. This article reviews the molecular genetic features, clinical characteristics, and therapeutic strategies of GNAO1 gene-associated dystonia, thereby increasing the knowledge of clinicians about GNAO1 gene-associated dystonia and preventing underdiagnosis and misdiagnosis in clinical practice.

Objective To investigate the exposure level of radioactive hazard factors and the health management of radiation workers in non-medical radiation institutions (excluding military institutions) in Jinan, China through radioactive hazard factor monitoring, to identify the weak links, and to provide a scientific basis for future work priorities. Methods According to the monitoring plan formulated by Jinan Municipal Health Commission, the task undertaking institutions at all levels in Jinan investigated the types of radioactive hazard factors, detection, training, and health monitoring of 101 non-medical radiation institutions in Jinan. In addition, the workplace radiation levels were detected in 25 institutions of 6 types of monitoring objects, including industrial flaw detection, non-medical accelerator, non-sealed radioactive material workplace, nuclear instrument, baggage detector, and others. Results The investigation objects included institutions engaged in industrial flaw detection, nuclear instrument, luggage detector, non-medical accelerator, non-sealed source workplace, and others. Of these institutions, 91.84% were equipped with radiation protection detectors, 92.86% were equipped with personal dose alarm, 97.73% were equipped with personal protective equipment, 94.36% performed radiation protection training, 92.69% employed radiation workers with certificates, 95.77% performed personal dose detection, 94.83% performed occupational health examination, and 100.00% were qualified for radiation protection detection in workplace. Conclusion There is still a gap between the radiation protection status of non-medical institutions in Jinan and the national regulations and standards, so it is necessary to further strengthen supervision and law enforcement and make greater efforts in training and publicity.

Objective:To investigate the effects and the mechanism of Calcyclin-binding protein (CacyBP) on the proliferation and invasion of non-small cell lung cancer (NSCLC) cells.Methods:Six lung cancer tissues and paired normal lung tissues were collected from NSCLC patients who underwent surgical treatment in Jinan Central Hospital during 2016. The expression of CacyBP in these tissues was examined by western blot. The protein and mRNA expression of CacyBP in human bronchial epithelial cells (16HBE), NSCLC cell lines including A549, H1299, H460 and H1975 were examined by western blot and reverse transcription-polymerase chain reaction (RT-PCR), respectively. RNAi and shRNA against negative control (NC) or CacyBP were transfected into A549 cell which were denoted as siNC group, siCacyBP-1 group, sicacyBP-2 group, shNC group and shCacyBP group, respectively. Control and Flag-CacyBP plasmids were transfected into A549 cells which were denoted as NC group and Flag-CacyBP group, respectively. Cell counting kit-8 (CCK-8), plate clone formation assay and flow cytometry assay were used to assess cell proliferation ability and cycle of A549. Wound healing assay and transwell assay were used to assess abilities of A549 cells migration and invasion. The protein expressions of epithelial-mesenchymal transition (EMT) markers including E-cadherin, N-cadherin, Snail1, Vimentin, and phosphorylation of protein kinase B (p-Akt) were examined in CacyBP depleted or overexpressed A549 cells.Results:The CacyBP protein level in NSCLC tissues was 0.41±0.23, significantly higher than 0.11±0.04 in normal lung tissues ( P<0.05). The CacyBP protein expression levels in different NSCLC cell lines including A549, H1299, H460 and H1975 were 0.35±0.01, 0.38±0.01, 0.32±0.01 and 0.41±0.01, respectively, which were significantly higher than 0.03±0.01 in 16HBE cells ( P<0.05). The result of RT-PCR was consistent with that of western blot. Compared with siNC group (absorbance was 1.54±0.03), siCacyBP-1 group and siCacyBP-2 group showed decreased cell proliferation (absorbances were 1.38±0.04 and 1.34±0.03, P<0.05). The number of cell colony in shNC group was 41.33±3.21, significantly higher than 22.00±3.61 in shCacyBP group ( P<0.05). The proportion of G 1 phase in shCacyBP group was (61.35±5.45)%, higher than (49.61±1.54) % in shNC group ( P<0.05). The proportion of S phase was (25.41±3.21)%, which was lower than (38.68±0.46)% of shNC group ( P<0.05). The cell migration rate of shCacyBP group was (12.67±0.71)%, which was significantly lower than (35.50±2.07)% of shNC group ( P<0.05). The numbers of cell migration and invasion in shNC group were 406.33±7.37 and 92.33±8.50, respectively, which were significantly higher than 224.67±10.01 and 66.00±7.94 in shCacyBP group ( P<0.05). Compared with siNC group, the expression of epithelial marker E-cadherin was up-regulated, while the expressions of mesenchymal markers including N-cadherin, Vimentin, Snail1 and p-Akt were down-regulated in CacyBP depleted A549 cells. Compared with NC group, overexpression of CacyBP inhibited E-cadherin expression while promoted the expressions of N-cadherin, Snail1, Vimentin and p-Akt, which could be restored by LY294002. Conclusion:CacyBP may promote the proliferation and invasion of NSCLC cells by regulating Akt signal pathway.
