Objective To explore the alterations of protein phosphatase-2A (PP-2A) in lymphocytes in mild cognition impairment (MCI) and Alzheimer's disease (AD).Methods The activity PP-2A of was measured by ~(32)p liquid seintillography for incorporated radioactivity in control group(n=11) , the MCI group(n=11),and the AD group(n=11).The expression of PP-2A was determined by Western blot.Results In the control group,the activity of PP-2A (1.01?0.09) and the expression of PP-2A (0.96?0.07) were high while in the MCI group,the activity of PP-2A (0.71?0.12) and the expression of PP-2A (0.80?0.05) were decreased (both P

OBJECTIVETo explore the mechanism of tau hyperphosphorylation and the effect of LiCl on tau phosphorylation and the memory retention deficits in streptozotocin-induced diabetes mellitus (DM) rats.

METHODSThe rats were randomly divided into control, DM, DM + NaCl, and DM + LiCl groups and diabetes was induced by streptozotocin. The activity of glycogen synthase kinase-3 (GSK-3) was measured by 32P-labelling. The level of tau phosphorylated and changes of memory retention were examined by Western blotting and step down test, respectively.

RESULTSCompared with control group, the activity of GSK-3 and tau phosphorylation was increased, and the memory retention was impaired in DM group. When the rats were treated with LiCl, the activity of GSK-3 and hyperphosphorylation of tau were significantly arrested (P < 0.05, P < 0.01), and the memory retention deficit was significantly improved (P < 0.05).

CONCLUSIONThe hyperphosphorylation of tau can be induced by activation of GSK-3 in diabetic rats. Lithium protects tau from hyperphosphorylation and may rescue memory retention in the rats by inhibiting GSK-3 activity.

Objective:To investigate the status of the vestibular function of the patients with chronic positional symptoms after peripheral acute vestibular syndrome (AVS) and the curative effect of the vestibular rehabilitation therapy (VRT). Method:Using caloric test (CT), head shaking nystagmus test (HST), cervical vestibular evoked myogenic potentials as well as ocular vestibular evoked myogenic potentials to estimate the function of semicircular canal and otolith organs. The patients with normal VEMPs are divided as Group A. Otherwise are as Group B. Both groups are treated with VRT. The curative effect is estimated by vestibular symptom index (VSI) and Berg balance scale (BBS). Result:Thirty-three of 37 patients (86.5%) had an abnormal result of CT and HST, with 23 of these patients (65.7%) had an abnormal of both test. Twenty-two patients (59.5%) were in Group A and 15 (40.5%) in Group B. Before the therapy, Group B had a higher score of the balance and dizziness symptoms of VSI (P<0.05), and Group A had a higher score of the BBS (P<0.05). After the therapy, the VSI scores of both groups dropped and scores of the BBS raised. Conclusion:Patients with chronic positional symptoms after peripheral AVS have dynamic vestibular lesions to different extents. Those with otolith organs lesions tend to have a worse function of balance. Nevertheless, patients have a better off after VRT.

OBJECTIVETo evaluate chest radiographic findings of children with 2009 influenza (H1N1) virus infection.

METHODData of 235 patients who had microbiologically confirmed H1N1 infection and available chest radiograph obtained between May 1(st) 2009 and Jan. 31(st) 2010 were retrospectively analyzed. The final study group was divided on the basis of clinical course [group 1 mild, outpatients without hospitalization (n = 172); group 2 moderate, inpatients with brief hospitalization (n = 49); group 3 severe, ICU admission (n = 14)]. Four pediatric radiologists reviewed all the chest radiographs of lung parenchyma, airway, pleural abnormalities and also anatomic distribution of the disease.

RESULTNo significant sex or age differences were found among the study groups (P > 0.05). The mean interval between the onset of clinical symptom and the initial chest radiography was (5.91 ± 1.64) days (group 1), (3.60 ± 1.43) days (group 2) and (1.21 ± 0.41) days (group 3), respectively. The differences among the three groups were significant statistically (χ(2) = 13.368, P < 0.01). The ratio of abnormality presented at initial chest X-ray was 79.7% in group 1, 91.8% in group 2 and 100% in group 3. Radiographically, there were prominent peribronchial markings (group 1, 55.2%; group 2, 83.7%; and group 3, 78.6%), consolidation (group 1, 34.3%; group 2, 69.4%; and group 3, 100.0%), hyperinflation (group 1, 22.1%; group 2, 44.9%; and group 3, 50.0%) and ground glass opacity (group 1, 0.6%; group 2, 2.0%; and group 3, 14.3%) in the chest radiographs. The differences of presenting were statistically significant (P < 0.01). In the severe group, the lesions distributed diffusely and asymmetrically with multi-lobe involvements.

CONCLUSIONIn children with 2009 influenza A H1N1 viral infection, the interval between the onset of clinical symptom and initial chest radiography, the ratio of abnormality presented at initial chest X-ray film and the severity of chest film are parallel to their clinical situation.

OBJECTIVETo investigate the alteration of beta-amyloid (Abeta) and glutamate transporter in the brain cortex of diabetes mellitus (DM) rats and the underlying mechanism.

METHODSThe rats were randomly divided into control, DM, DM +NaCl, and DM +LiCl groups and diabetes was induced by streptozotocin. The activity of glycogen synthase kinase-3 (GSK-3) and the function of glutamate transporter were measured by 32P-labelling. The amount of Abeta was determined by enzyme-linked immunosorbentassay.

RESULTSIn DM group, the level of Abeta40 increased (P < 0.01), but the function of glutamate transporter was impaired (P < 0.05). The activity of GSK-3 was stimulated (P < 0.05). Compared with DM group, the level of Abeta40 was restored (P < 0.01), and the function of glutamate transporter was enhanced (P < 0.05) in LiCl treated group, accompanied by a decreased activity of GSK-3.

CONCLUSIONOverproduction of Abeta and impaired glutamate transporter exist in DM rats, and increase of GSK-3 may play a crucial role in this process.

OBJECTIVETo explore whether vimentin (VIM) mediates the activation of inflammasome in mice with EV71 infection in the central nervous system.

METHODSForty VIM knockout mice (VIM, 3 to 5 days old) were randomly divided into control group and infection group. The infection group was intraperitoneally injected with EV71 (10 TCID), while the control group was injected with PBS (10 µL); another 40 wild-type mice (WT, 3 to 5 days old) were grouped in the same manner. The general conditions of mice were observed each day. Western blotting, ELISA, and RT-PCR were used to measure the levels of IL-1β and casepase-1 in the brain or cerebrospinal fluid. The pathological changes in the cerebella and brain were observed using immunohistochemistry.

RESULTSCompared with the control group, the VIM mice infected with EV71 showed no significant changes in NLRP3, IL-1β or caspase-1 expression. The WT mice infected with EV71 showed obviously increased NLRP3, IL-1β, and caspase-1 expressions in the central nervous system. The neurons of infected VIM mice exhibited milder cell damage than the those in WT mice.

CONCLUSIONVIM mediates the activation of inflammasome and promotes brain inflammation and neuronal damage in mice with EV71 infection in the central nervous system.

Objective: To investigate the surgical indications and perioperative clinical outcomes of pelvic exenteration (PE) for locally advanced, recurrent pelvic malignancies and complex pelvic fistulas. Methods: This was a descriptive study.The indications for performing PE were: (1) locally advanced, recurrent pelvic malignancy or complex pelvic fistula diagnosed preoperatively by imaging and pathological examination of a biopsy; (2)preoperative agreement by a multi-disciplinary team that non-surgical and conventional surgical treatment had failed and PE was required; and (3) findings on intraoperative exploration confirming this conclusion.Contraindications to this surgical procedure comprised cardiac and respiratory dysfunction, poor nutritional status,and mental state too poor to tolerate the procedure.Clinical data of 141 patients who met the above criteria, had undergone PE in the Sixth Affiliated Hospital of Sun Yat-sen University from January 2018 to September 2022, had complete perioperative clinical data, and had given written informed consent to the procedure were collected,and the operation,relevant perioperative variables, postoperative pathological findings (curative resection), and early postoperative complications were analyzed. Results: Of the 141 included patients, 43 (30.5%) had primary malignancies, 61 (43.3%) recurrent malignancies, 28 (19.9%) complex fistulas after radical resection of malignancies,and nine (6.4%)complex fistulas caused by benign disease. There were 79 cases (56.0%) of gastrointestinal tumors, 30 cases (21.3%) of reproductive tumors, 16 cases (11.3%) of urinary tumors, and 7 cases (5.0%) of other tumors such mesenchymal tissue tumors. Among the 104 patients with primary and recurrent malignancies, 15 patients with severe complications of pelvic perineum of advanced tumors were planned to undergo palliative PE surgery for symptom relief after preoperative assessment of multidisciplinary team; the other 89 patients were evaluated for radical PE surgery. All surgeries were successfully completed. Total PE was performed on 73 patients (51.8%),anterior PE on 22 (15.6%),and posterior PE in 46 (32.6%). The median operative time was 576 (453,679) minutes, median intraoperative blood loss 500 (200, 1 200) ml, and median hospital stay 17 (13.0,30.5)days.There were no intraoperative deaths. Of the 89 patients evaluated for radical PE surgery, the radical R0 resection was achieved in 64 (71.9%) of them, R1 resection in 23 (25.8%), and R2 resection in two (2.2%). One or more postoperative complications occurred in 85 cases (60.3%), 32 (22.7%)of which were Clavien-Dindo grade III and above.One patient (0.7%)died during the perioperative period. Conclusion: PE is a valid option for treating locally advanced or recurrent pelvic malignancies and complex pelvic fistulas.

Copy number variations (CNVs), which can affect the role of long non-coding RNAs (lncRNAs), are important genetic changes seen in some malignant tumors. We analyzed lncRNAs with CNV to explore the relationship between lncRNAs and prognosis in bladder cancer (BLCA). Messenger RNA (mRNA) expression levels, DNA methylation, and DNA copy number data of 408 BLCA patients were subjected to integrative bioinformatics analysis. Cluster analysis was performed to obtain different subtypes and differently expressed lncRNAs and coding genes. Weighted gene co-expression network analysis (WGCNA) was performed to identify the co-expression gene and lncRNA modules. CNV-associated lncRNA data and their influence on cancer prognosis were assessed with Kaplan-Meier survival curve. Multi-omics integration analysis revealed five prognostic lncRNAs with CNV, namely
