Objective To investigate the dynamic changes of hippocampal insulin like growth factor-1(IGF-1)/IGF-1 receptor (1GF-1 R) signaling pathway and learning and memory function and to investigate the possible mechanisms of vascular dementia (VaD).Methods A rat chronic cerebral hypoperfusion model was induced by using permanent bilateral common carotid artery ligation.At day 3,1 and 2 weeks,1,2 and 4months after modeling,Morris water maze test was used to evaluate the changes of learning and memory function in rats.HE staining was used to observe the morphological changes of hippocampal neurons.Enzymelinked immunosorbent assay was used to detect the dynamic changes of IGF-1,IGF-1R,Akt and p-Akt in hippocampal tissue.Results One month after modeling,the rats of a model group began to appear significant learning and memory dysfunction.The numbers of crossing the platform were significant lower than those in a sham operation group (1.91 ±0.45 times vs.3.95 ± 1.64 times; t =17.251,P =0.000).With the extension of ischemia time,the degree of injury of pyramidal cells in hippocampal CA1 region aggravated gradually in the model group.The levels of IGF-1 and p-Akt in hippocampal tissue increased early after modeling in the model group,and then they declined gradually to the normal levels.The levels of IGF-1 (0.09 ± 0.05 ng/mg vs.0.20 ±0.03 ng/mg; t =-5.263,P =0.003) and p-Akt (12.50± 1.40 pg/mg vs.17.13 ± 0.87 pg/mg; t =- 5.651,P =0.000) at 1 month were significantly lower than those in the sham operation group and continued to 4 months.There were no significant changes in the levels of IGF-1R and Akt.Conclusions The down-regulation of IGF-1/IGF-1R signaling pathway may be one of the pathogeneses of VaD.

Objective To explore the effects of enhanced recovery after surgery (ERAS) on postoperative recovery, psychological state and complications of patients with laparoscopic gastrointestinal surgery. Methods Ninety-eight patients with laparoscopic gastrointestinal surgery admitted to Huzhou Central Hospital from January 2016 to December 2017 were enrolled and they were divided into two groups (49 cases in each group) according to difference in nursing. During peri-operative period, the routine nursing group was given routine nursing; while the ERAS nursing group received the nursing of ERAS. The postoperative recovery, inflammatory response and nutritional status, complications, psychological state and nursing satisfaction were compared between the two groups. Results Compared with the routine nursing group, the gastrointestinal tract exhaust time, common food intake time, incision healing time, ambulation time and hospital stay were significantly shorter in ERAS nursing group [gastrointestinal tract exhaust time (days): 2.43±1.02 vs. 3.46±1.15, common food intake time (days): 4.24±1.36 vs. 6.23±1.52, incision healing time (days): 7.62±1.54 vs. 9.63±1.63, ambulation time (days): 8.80±2.32 vs. 11.24±2.02, hospital stay (days):10.23±2.12 vs.14.56±2.37, all P < 0.05]. After operation, the high-sensitivity C-reactive protein (hs-CRP) in the two groups was increased first and then decreased, and the levels of transferrin (TRF) and prealbumin (PA) were decreased first and then increased, and the differences were statistically significant at different time points within-groups (P < 0.05), and the changes of indexes in the 5 days after operation in the ERAS nursing group were more significant than those in the routine nursing group [hs-CRP (mg/L): 27.4±6.2 vs. 35.6±9.1, TRF (g/L): 1.89±0.05 vs. 1.81±0.06, PA (mg/L):340±20 vs. 280±20, all P < 0.05]. The postoperative incidences of nausea and vomiting and sore throat in ERAS nursing group were significantly lower than those in routine nursing group [nausea and vomiting: 32.65% (16/49) vs. 67.35% (33/49), sore throat: 12.24% (6/49) vs. 51.02% (25/49), both P < 0.05], and there were no significant differences in postoperative incidences of abdominal distension, incision infection, pulmonary infection and anastomotic leakage between the two groups [abdominal distension: 4.08% (2/49) vs. 6.12% (3/49), incision infection: 4.08% (2/49) vs. 6.12% (3/49), pulmonary infection: 2.04% (1/49) vs. 6.12% (3/49), anastomotic leakage: 2.04% (1/49) vs. 4.08% (2/49), all P >0.05]. The scores of self-rating anxiety scale (SAS) at discharge in the two groups were lower than those before operation, and the degree of decrease in ERAS nursing group was greater than that in routine nursing group (39.21±4.64 vs. 46.56±4.53, P < 0.05). The nursing satisfaction rate in ERAS nursing group was significantly higher than that in routine nursing group [95.92% (47/49) vs. 77.55% (38/49), P < 0.05]. Conclusion ERAS for laparoscopic gastrointestinal surgery not only can promote the recovery of gastrointestinal function, improve the nutritional status and reduce inflammatory response and postoperative complications, but also can relieve anxiety, shorten hospital stay and elevate nursing satisfaction, therefore it is worthy to promote and apply in clinical nursing.

Objective: Diminished ovarian reserve (DOR) is a disorder characterized by impaired ovarian function. Sleep disorders are disruptions of the circadian rhythm, which appears to be closely linked to reproductive systems. This study aimed to investigate the impact of poor sleep quality on the ovarian reserve of childbearing-age women. Methods: A cross-sectional study was conducted in China from June 2021 to March 2023. In total, 102 participants diagnosed with chronic insomnia disorder were included in the study. Questionnaires were administered to assess participants' menstrual patterns, insomnia severity, anxiety, and depression. The anti-Müllerian hormone level and the basal antral follicle count were measured for ovarian reserve evaluation. Correlation analysis and ordinal logistic regression analysis were conducted. Results: The women with insomnia presented high percentages of hypomenorrhea, premenstrual syndrome, and dysmenorrhea (78.4%, 74.5%, and 46.1%, respectively). Severe sleep disorder in the past month was identified as an independent risk factor for hypomenorrhea and premenstrual syndrome (odds ratio [OR], 2.64 and OR, 2.688; p<0.05). The prevalence of DOR among women with insomnia (33.3%) was significantly higher than the average reported in previous studies for young women. Insomnia duration exceeding 1 year was determined to be an independent risk factor for DOR in women aged 36 to 40 years (OR, 4.5; p=0.033). Conclusion This study highlights the association between sleep disorders and menstrual problems. Prolonged poor sleep quality in women aged 36 to 40 years was identified as a significant risk factor for DOR. We should pay more attention to improving sleep quality in order to maintain normal ovarian function.

OBJECTIVE: To evaluate the early predictive and diagnostic significance of the acute kidney injury (AKI) associated biomarkers for patients in the intensive care unit (ICU).
 METHODS: From January to June, 2014, relevant clinical data of participants were collected upon admission to the intensive care unit (ICU) in Affiliated Hospital of Zunyi Medical College. Levels of serum cystatin C (sCys C), neutrophil gelatinase-associated lipocalin (sNGAL), urinary neutrophil gelatinase-associated lipocalin (uNGAL), urinary kidney injury molecule-1 (uKIM-1), interleukin-18 (uIL-18), and N-acetyl-beta-D-glucosaminidase (uNAG) were detected by enzyme linked immune sorbent assay (ELISA), and compared between AKI and non-AKI patients. Diagnostic significance of these biomarkers was evaluated by a receiver operating characteristic (ROC) curve and the area under the ROC curve.
 RESULTS: A total of 176 patients were enrolled in this study. Among them, 71 patients were diagnosed as AKI, in which 57 patients hospitalized with AKI and 14 developed AKI after 24 h hospitalization. The renal replacement therapy ratio was increased with the progress of clinical stage for AKI. AKI mortality rate was 18.8% (46.5% of the total number of deaths). The levels of sCys C, sNGAL, uNGAL, and uIL-18 in AKI patients were increased compared with those in the non-AKI patients (P<0.05). With the progress of AKI, sCys C, and uNGAL levels were also elevated. In 14 patients who suffered from AKI 24 h after hospitalization, the average levels of sCys C, uNGAL, uIL-18, and uKIM-1 were significantly increased (P<0.05). Sensitivity and specificity of the uNGAL, sCys C, and uIL-18 in AKI diagnosis were 97.2%, 76.1%, 54.9% and 93.3 %, 96.2%, 78.1%, respectively. The areas under the ROC curve of uNGAL, sCys C, and uIL-18 were 0.99, 0.90, and 0.69, respectively.
 CONCLUSION uNGAL, sCys C and uIL-18 can be used to predict and diagnose AKI, and to evaluate the AKI clinical stage.

Alzheimer′s disease is a progressive neurodegenerative disease that requires medication to improve patient symptoms, but there is an individual difference in the efficacy. In this paper, the correlation between single nucleotide polymorphism and the drug efficacy of Alzheimer′s disease (AD) in the past 20 years was searched through the databases of China National Knowledge Infrastructure, VIP Database, Wanfang Database, Pubmed, Springer Link and Cochrane Library with key words of Alzheimer′s disease, drug efficacy, single nucleotide polymorphism. The correlation between AD drug efficacy difference and gene single nucleotide polymorphism was reviewed, including ABCA1, ApoE, ChAT, CHRNA7, IL-6, A2M, CYP2D6, BChE, 5HT2a, PON-1 and ESR1 genes, so as to provide a reference basis for clinicians to select drugs in the treatment of AD.

Background and purpose:Long noncoding RNA(lncRNA)can regulate gene transcription,mRNA shear,stabilization and translation,and it is an important regulatory factor in a variety of biological processes.This study aimed to investigate the expression and clinical features of lncRNA FLJ30679 in oral squamous cell carcinoma(OSCC)and its effect on the malignant biological behavior of OSCC.Methods:The expression of FLJ30679 in head and neck squamous cell carcinoma(HNSCC)tissues and normal tissues was analyzed by the UCSC Xena database for expression and prognosis.The expression of FLJ30679 in OSCC cell lines was detected by real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR).The subcellular localization of FLJ30679 in OSCC cells was detected by RNA nuclear-cytoplasmic fractionation assays.FLJ30679 Smart Silencer was used to establish the FLJ30679 knockdown group(SS-FLJ30679),and overexpression plasmid of FLJ30679 was used to establish FLJ30679 overexpression group(FLJ30679).The effects of altered FLJ30679 expression on the proliferative and migration capacity of OSCC cells were examined by cell counting kit-8(CCK-8)and transwell migration assays.RTFQ-PCR and Western blot were used to determine the effect of altered FLJ30679 expression on the expression of epithelial-mesenchymal transition(EMT)-related genes in OSCC cells.The effects of altered FLJ30679 expression on the phosphoinositide 3-kinase(PI3K)/protein kinase(AKT)pathway were detected by Western blot.Results:Online query of database showed that FLJ30679 expression was higher in HNSCC tissues compared to normal tissues(P＜0.01).HNSCC patients with higher FLJ30679 expression had lower overall survival(P＜0.01).The RTFQ-PCR results showed that FLJ30679 was expressed at a higher level in six OSCC cell lines compared with normal cells,and was predominantly localized in the nucleus.The ability of OSCC cells in the SS-FLJ30679 group to proliferate and migrate was significantly lower compared with the SS-NC group(P＜0.01).OSCC cells in the FLJ30679 overexpression group had significantly higher proliferative and migratory capacities than those in the vector group(P＜0.001).RTFQ-PCR and Western blot results showed that FLJ30679 knockdown resulted in upregulation of mRNA and protein expression levels of E-cadherin(P＜0.01)and downregulation of mRNA and protein expression levels of N-cadherin and vimentin(P＜0.01).FLJ30679 overexpression resulted in downregulation of protein expression levels of E-cadherin(P＜0.01)and upregulation of mRNA and protein expression levels of N-cadherin and vimentin(P＜0.05).Western blot results showed that knockdown of FLJ30679 resulted in decreased protein expression levels of phosphorylated-PI3K(p-PI3K)and phosphorylated-AKT(p-AKT)(P＜0.001),and overexpression of FLJ30679 resulted in increased protein expression levels of p-PI3K and p-AKT(P＜0.01).Conclusion:The expression of FLJ30679 was increased in OSCC tissues and cells.It promoted the proliferation and migration ability of OSCC cells,which may be caused by FLJ30679 promoting EMT via PI3K/AKT pathway.

Objective:To compare the diagnostic efficacy of 22 G fine needle aspiration (FNA) needles and 22 G end-cutting fine needle biopsy (FNB) needles for solid pancreatic lesion using both cytological and histological examination.Methods:Clinical data of 116 patients who underwent endoscopic ultrasound-guided fine needle aspiration/biopsy (EUS-FNA/FNB) at the Digestive Endoscopy Center of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from June 2022 to March 2023 were retrospectively analyzed. Sixty-three patients sampled with 22 G FNA needles were the FNA group, and 53 sampled with 22 G FNB needles were the FNB group. The diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and cytological and histological diagnostic yield of FNA needles and FNB needles for solid pancreatic lesions were compared.Results:There were no significant differences in age, gender, lesion location, lesion size, or the number of passes between the FNA group and the FNB group ( P>0.05). There were no significant differences in the diagnostic accuracy [93.7% (59/63) VS 90.6% (48/53), P=0.730], sensitivity [93.0% (53/57) VS 90.2% (46/51), P=0.732], specificity [100.0% (6/6) VS 100.0% (2/2), P=1.000], positive predictive value [100.0% (53/53) VS 100.0% (46/46), P=1.000] and negative predictive value [60.0% (6/10) VS 28.6% (2/7), P=0.335] of combined cytology and histology in distinguishing benign and malignant lesions between the two groups. In the FNA group, the diagnostic accuracy of combined cytology and histology was higher than cytology alone [93.7% (59/63) VS 81.0% (51/63), P=0.008], and was higher than histology alone without statistical significance [93.7% (59/63) VS 87.3% (55/63), P=0.125]. In the FNB group, the diagnostic accuracy of combined cytology and histology was higher than cytology alone [90.6% (48/53) VS 69.8% (37/53), P=0.001], but not than histology alone [90.6% (48/53) VS 90.6% (48/53)， P=1.000]. For solid masses located in pancreatic body/tail, the diagnostic accuracy for malignancy by histology using FNB needles tended to be higher than that of FNA needles [100.0% (17/17) VS 81.3% (26/32), P=0.080]. Conclusion:Both FNA needles and FNB needles exhibit adequate diagnostic yield for solid pancreatic masses when combining cytology and histology. FNB needles may offer a higher histological diagnostic yield.
