Objective:To explore the influencing factors for postoperative delirium in General Ward of Neurosurgery and evaluate the influence of serum acetylcholinesterase level in it.Methods:A retrospective study was performed. Two hundred and ninety-eight patients accepted surgery and diverted into General Ward of Neurosurgery in our hospital from January 2021 to July 2021 were chosen in our study. The 4AT delirium scoring tool was used to evaluate whether the patients had delirium, and these patients were, then, divided into non-delirium group and delirium group. The preoperative general data, history of deseases and laboratory results (serum acetylcholinesterase level) were collected. Univariate analysis and multivariate Logistic regression analysis were used to determine the independent factors affecting the occurrence of postoperative delirium, especially the relation between preoperative serum acetylcholinesterase level and postoperative delirium. Receiver operating characteristics (ROC) curve was drawn to evaluate the predictive value of serum acetylcholinesterase in postoperative delirium.Results:The incidence of postoperative delirium in 298 patients in General Ward of Neurosurgery was 24%, including 225 patients into the non-delirium group and 73 patients into the delirium group. There were significant differences between the two groups in the proportions of patients having resuscitation in anesthesia ICU, using postoperative analgesic pump and having alcoholism history, surgical duration, intraoperative bleeding, proportion of patients accepting skull base surgery, proportion of patients remaining awake 2 h after surgery, and incidence of bilateral frontal lobe pneumatosis after surgery ( P<0.05). Preoperative serum acetylcholinesterase level in delirium group ([2.35±0.49] U/mL) was significantly lower than that in non-delirium group ([2.78±0.48] U/mL, P<0.05). Preoperative serum acetylcholinesterase level ( OR=0.116, 95%CI: 0.034-0.394, P=0.001), postoperative resuscitation in anesthesia ICU ( OR=0.043, 95%CI: 0.002-0.878, P=0.041), keeping awake 2 h after surgery ( OR=7.641, 95%CI: 1.675-34.858, P=0.009), surgical duration ( OR=1.887, 95%CI: 1.192-2.987, P=0.007), intraoperative bleeding ( OR=1.010, 95%CI: 1.006-1.014, P<0.001), and skull base surgery ( OR=6.700, 95%CI: 1.907-23.547, P=0.003) were all independent influencing factors for postoperative delirium in patients in General Ward of Neurosurgery. The area under ROC curve for serum AchE level to predict the occurrence of postoperative delirium was 0.735(95%CI: 0.679-0.800, P<0.001); when the cut-off value was 2.67 U/mL, the sensitivity and specificity were 64% and 75%. Conclusions:Skull base surgery, keeping awake 2 h after surgery, long surgical duration and large amount of intraoperative bleeding can promote the occurrence of postoperative delirium; admission to anesthesia ICU after surgery can reduce the occurrence of delirium. When the preoperative serum AchE level is less than 2.67 U/mL, the possibility of postoperative delirium should be warned.

Two-dimensional polyacryiamide gel electrophoresis (2D-PAGE) and matrixassisted laser desorption/ionization tandem time-of-flight mass spectrometry (MALDI-TOF/TOF-MS), incorporated with online database searching, were performed to investigate differential proteins of breast cancer and adjacent normal breast tissues. Considering that serum albumin is abundantly presented in normal control samples, 15 differential spots detected in 11 out of 12 (91.7%) breast cancer samples were identified by online SIENA-2DPAGE database searching and MALDI-TOF/TOF-MS analysis. The results indicate that pathological changes of breast cancer are concerned with augmentation of substance metabolism, promotion of proteolytic activity, decline of activity of some inhibitors of enzymes, and so on. Some important proteins involved in the pathological process of breast cancer with changed expression may be useful biomarkers, such as alpha-1-antitrypsin, EF1-beta, cathepsin D, TCTP, SMT3A, RPS12, and PSMA1, among which SMT3A,RPS12, and PSMA1 were first reported for breast cancer in this study.

OBJECTIVETo explore the pathological basis of diffusion-weighted imaging (DWI) findings in hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE).

METHODSDWI was performed in 15 patients with HCC treated by TACE within 24 - 48 hours before II-phase operation. The DWI findings of the liver lesions were analyzed and correlated with pathological findings including macroscopic observation, HE staining and immunohistochemical staining for bFGF.

RESULTS(1) The viable tumor area showed mostly hypersignal intensity (12/15), whereas coagulative necrotic lesions showed hyposignal (8/15) or isosignal intensity (6/15). The ADC values of zones of viable tumor and necrosis in tumor were (1.42 +/- 0.16) x 10(-3) mm(2)/s and (1.58 +/- 0.18) x 10(-3) mm(2)/s, respectively. There was a significant difference of ADC values between the two zones (t = 2.618, P < 0.05). (2) There was a significant difference in ADC values of viable tumor between well and poorly differentiated tumors (t = -2.646, P < 0.05). The distinction of ADC values of the whole tumor was significant among tumors with different degree of necrosis (chi(2) = 7.236, P < 0.05). (3) A negative correlation was observed between bFGF protein expression index and ADC values of viable parts of the tumors in the study group (r = -0.552, P = 0.033).

CONCLUSIONDWI shows certain characteristic features of the HCC after TACE, and can be used to distinguish viable and necrotic tumor tissues in HCC after TACE.

BACKGROUNDThe autosomal dominant form of retinitis pigmentosa (ADRP) can be caused by mutations in 14 genes and further loci remains to be identified. This study was intended to identify mutations in a Chinese pedigree with ADRP.

METHODSA large Chinese family with retinitis pigmentosa was collected. The genetic analysis of the family suggested an autosomal dominant pattern. Microsatellite (STR) markers tightly linked to genes known to be responsible for ADRP were selected for linkage analysis. Exons along with adjacent splice junctions of PRPF31 were amplified by polymerase chain reaction (PCR) and screened by direct sequencing.

RESULTSThe caused gene of ADRP was mapped to 19q13.4 between markers D19S572 and D19S877, with a maximum LOD score of 3.01 at marker D19S418 (recombination fraction = 0).

CONCLUSIONThe affected gene linked to the 19q13.4 in a Chinese family with ADRP, which is different from other mutations at the same loci in other Chinese families.

OBJECTIVETo study the value of apolipoprotein H (apoH) gene expression in peripheral blood mononuclear cell (PBMC) and urinary N-Acetyl-beta-D-Glucosaminidase (NAG) and retinal-binding protein (RBP) in the early diagnosis of renal function damage in neonates.

METHODSSixty sick neonates who renal function damage probably occurred were enrolled. The blood and urinary samples were collected twice within 48 hrs following admission, with an interval of 12-24 hrs. Expression of apoH gene in PBMC was determined with RT-PCR. The levels of blood urea nitrogen (BUN) and creatinine, and urinary activities of NAG and RBP were measured with enzymatic reaction.

RESULTSThe abnormal rates of blood apoH and urinary NAG and RBP were 73.3%, 83.3% and 76.7%, respectively in the first detection. The second detection for blood apoH and urinary NAG and RBP showed abnormal rates of 70.0%, 66.7% and 76.7%, respectively. There were no significant differences in the abnormal rates between the three markers either in the first or the second detection (P>0.05). Beside there were no significant significances in the abnormal rates between urinary NAG and blood BUN in the second detection, the abnormal rates of blood apoH and urinary NAG and RBP in both detections were significantly higher than those of BUN or creatinine (P<0.01 or 0.05).

CONCLUSIONSThere are identical values of blood apoH gene expression and urinary NAG and RBP in the early diagnosis of renal function damage in neonates. The above three markers are more sensitive to early renal function damage than blood BUN and creatinine.

Objective: This meta-analysis aims to refine the understanding of the optimal choice between different cage shapes in transforaminal lumbar interbody fusion (TLIF) by systematically comparing perioperative data, radiological outcomes, clinical results, and complications associated with banana-shaped and straight bullet cages. Methods: A meticulous literature search encompassing PubMed, Embase, Scopus, Web of Science, China Knowledge Network, and Wanfang Data was executed up to October 5, 2023. Inclusion criteria focused on studies comparing banana-shaped and straight bullet cages in TLIF. The quality of included studies was assessed using appropriate tools such as the Newcastle-Ottawa Scale (NOS) for nonrandomized studies. Rigorous evaluations were performed for radiographic outcomes, including disc height (DH), segmental lordosis (SL), lumbar lordosis (LL), subsidence, and fusion rates. Clinical outcomes were meticulously evaluated using visual analogue scale (VAS), Oswestry Disability Index (ODI), and complications. Results: The analysis incorporated 7 studies, involving 573 patients (297 with banana-shaped cages, 276 with straight cages), all with NOS ratings exceeding 5 stars. No statistically significant differences were observed in operative time, blood loss, or hospitalization between the 2 cage shapes. Banana-shaped cages exhibited greater changes in DH (p = 0.001), SL (p = 0.02), and LL (p = 0.01). Despite statistically higher changes in ODI for straight cages (26.33, p < 0.0001), the actual value remained similar to banana-shaped cages (26.15). Both cage types demonstrated similar efficacy in VAS, complication rates, subsidence, and fusion rates. Conclusion Although banana-shaped cages can excel in restoring DH, SL, and LL, straight bullet cages can provide comparable functional improvements, pain relief, and complication rates.
