OBJECTIVETo evaluate the effects of prenatal stress on neurological functions after middle cerebral artery occlusion (MCAO) in adult offspring rats.

METHODSPregnant rats were randomly assigned to prenatal stress treatment, which was exposed to restraint three times daily in the last week of pregnancy, and no prenatal stress treatment. Adult male offspring rats were subjected to transient focal cerebral ischemia by MCAO. They were randomly divided into four groups: sham group, prenatal stress + sham group, MCAO group and prenatal stress + MCAO group (n = 10). After 24 hours of reperfusion, the neurological deficits were evaluated. The infarct size, cell apoptosis and expression of Caspase 3, cleaved Caspase 3 and Bcl-2 were detected.

RESULTSCompared with MCAO group, the neurological deficits, infarct size and apoptotic cells in prenatal stress + MCAO group were increased significantly (all P < 0.05). The expressions of Caspase 3 and cleaved Caspase 3 were much greater in prenatal stress + MCAO group than those of MCAO group, while the expression of Bcl-2 was significantly decreased in prenatal stress + MCAO group compared with MCAO group (all P < 0.05).

CONCLUSIONPrenatal stress might exacerbate neuroloeical deficits in the offspring rats after MCAO by increasing cell apoptosis.

Objective To study the diagnostic values of X-ray,CT and MRI for the hip joint lesion of the patient with ankylosing spondylitis (AS).Methods Totally 180 AS patients underwent the examinations of X-ray,CT and MRI from January 2014 to December 2015,and the hip joint lesion,clinical features and the efficacies of the three imaging techniques were observed.Results The rates for positive findings were 69.44％,71.11％ and 72.22％ respectively by X-ray,CT and MRI,and more than 90％ patients had the lesions occurred at the bilateral hip joints simultaneously.Hip joint lesion of AS had the imaging features of bone marrow and joint space changes,which related to the disease progress closely.Early positive signs consisted of medial joint space narrowing by X-ray,rear joint space narrowing by CT as well as bone marrow fat deposition (BMFD) and bone marrow edema (BME) by MRI.Conclusion X ray,CT and MRI all gain their advantages when used to diagnose the hip joint lesion of AS.X-ray behaves well in early diagnosis of medial joint space narrowing,while have disadvantages in displaying soft tissues and minute structures when compared with CT and MRI.CT displays the minute structure of hip joint clearly,and is not so good at soft tissue resolution as MRI.MRI gains the highest resolution for displaying soft tissues in the three techniques,and can show BMFD,BME and etc which can not be revealed by X-ray and CT.

Objective:To analyze the activity of lithium chloride (LiCl) against influenza virus A (H3N2) in human non-small cell lung cancer cells (A549).Methods:Different concentrations of LiCl were incubated with A549 cells, and the cytopathic effect (CPE) was observed after 24 hours, and the effect of LiCl on cell activity was determined by CCK-8 method. After H3N2 (MOI=1) infected A549 cells, different concentrations of LiCl were added and incubated for 24 hours, and the viral load was measured by real time/reverse transcription quantitative polymerase chain reaction (RT-qPCR), and the CPE was observed, and the viral titer was determined. Different concentrations of LiCl were incubated with A549 at 37 ℃ and 5% CO 2 for 2 hours, virus was added and incubated for 24 hours, and the viral load was determined by RT-qPCR. LiCl, H3N2 and A549 were incubated at 4 ℃ for 1 hour, 35 ℃, 5% CO 2 for 24 hours, and viral load was determined by RT-qPCR. H3N2 and A549 were incubated at 4 ℃for 1 hour, then different concentrations of LiCl were added, incubated at 35 ℃ with 5% CO 2 for 24 hours, and the viral load was determined by RT-qPCR. After H3N2 infected A549 cells, different concentrations of LiCl were added and incubated for 24 hours, and the viral RNA load and viral titer of the supernatant and cells were measured, respectively, and then the corresponding ratios of the supernatant and the cells were calculated. After H3N2 (MOI=10) and BV (MOI=1) infected A549 cells, different concentrations of LiCl were added for 24 h, and the viral load was determined by RT-qPCR. Results:When the concentration of LiCl was<50 mmol/L, the cell viability of A549>90%. Different concentrations of LiCl could significantly reduce the viral load of H3N2 ( P<0.000 1), and the CPE of the LiCl treatment group was more dose-dependent than that of the control group. LiCl did not inhibit viral replication by affecting the cell itself; Different concentrations of LiCl significantly inhibited the entry of H3N2 into A549 ( P<0.000 1), and also had a certain inhibitory effect on the adsorption of A549 cells ( P<0.1). LiCl did not affect the assembly and release of H3N2 ( P>0.05), and it was also found that LiCl had a broad spectrum of antiviral effects against multiple influenza virus strains ( P<0.000 1). Conclusions:LiCl may exert antiviral effect by inhibiting the adsorption and entry of H3N2 into A549 cells and the replication of H3N2 in A549 cells, which provides a data reference for the prevention and treatment of viral infection by LiCl.

OBJECTIVESThe National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) was used to determine the chronic prostatitis syndrome in young men (from 20 to 48 years old) of clinical validity.

METHODS227 patients with chronic prostatitis syndrome (CPS)/chronic pelvic pain syndrome and 32 patients with BPH were randomized to study using NIH-CPSI.

RESULTS1. The main manifestations of CPS patients were pain or uncomfort. Those were more common in CPS than BPH. 2. 79.30% CPS patients had a sensation of not emptying bladder completely after finished urinating, 44.93% patients had to urinate again less than two hours after finished urinating. 3. 51.51% patients with CPS have more effect on work, 90.31% patients on free life, and 68.72% patients on quality of life than BPH.

CONCLUSIONSAccording NIH-CPSI, the main manifestations of CPS are pain or uncomfort. CPS patients have more effect on work and quality of life.

Objective To analyse the correlation between the micrometastasis and early recurrence and prognosis in laryngeal cancer.Methods Total of 126 patients with laryngeal squamous cell carcinoma were included in the study.The micrometastasis was detected with hematoxylin and eosin staining(HE) and immunohistochemical staining for cytokeratin (CK) of the lymph node specimens after selective neck dissection( Ⅱ -Ⅳ).Chi-square test was used to analyse the relationship between the micrometastasis and early recurrence and prognosis,and Kaplan-Meier method was used for survival analysis.Results HE staining showed positive micrometastasis in 41 cases and negative micrometastasis in 85 cases in which 33 cases were positive staining for CK. With a following-up of mean 6.3 years,recurrence or metastasis occurred in 15 cases with positive micrometastasis detected by HE staining,14 cases with CK positive staining and 4 cases with CK negative staining.The correlation between micrometastasis and early recurrence was significant(P ＜ 0.01 ).The total 5-year survival rate was 79.8％,10-year survival rate was 60.5％.The 10-year survival rate(52.1％ ) of the patients with CK positive staining indicating micrometastasis was significantly higher than that of CK negative patients (81.2％,P ＜ 0.01 ). Conclusion Cervical micrometastasis predicts poor prognosis and early recurrence in patients with laryngeal squamous cell carcinoma.

OBJECTIVETo investigate the effects of losartan, a specific angiotensin II receptor blocker, on slowing progression of renal insufficiency in patients with biopsy-proven chronic allograft nephropathy (CAN) and the molecular mechanism of the therapy.

METHODSTwenty-two renal transplant recipients with biopsy-proven CAN (group A) were treated with losartan within two months after renal dysfunction for at least one year. Losartan was administered at a dose of 50 mg/d. Twenty-four recipients in the same fashion (group B) who never received angiotensin II receptor antagonist were studied as control. The investigation time for each patient lasted one year. Renal functions and concentrations of plasma and urine transforming growth factor-beta1 (TGF-beta1) were compared between the two groups at the initiation and end of the study. In group A, expressions of TGF-betal mRNA and immunofluorescence intensity of TGF-betal protein and pathological alterations in renal biopsy specimens were compared between before losartan therapy and after one year of the therapy.

RESULTSAt the initiation of the investigation, no significant differences were found between group A and group B in clinical data such as donor age, cold-ischemia time, HLA mismatch, levels of creatinine clearance (Ccr), plasma and urine TGF-beta1 concentrations. One year later, 14 of 22 (63.6%) patients showed stable or improved graft functions in group A, and 4 of 24 (16.7%) in group B. The difference was significant (P < 0.05). At the end of the study, urine TGF-betal concentration was 273.8 +/- 84.1 pg/mg x Cr in group A and 457.2 +/- 78.9 pg/mg x Cr in group B. During one year study period, loss of Ccr was 6.6 +/- 5.4 mL/min in group A and 16.2 +/- 9.1 mL/min in group B. Both of the differences were significant between the two groups (P < 0.01). No significant differences were found in plasma TGF-betal concentrations between the four values determined at the initiation and end of the study in the two groups (F = 2.56, P > 0.05). After one year losartan therapy, group A showed a significant decrease in expressions of TGF-beta1 mRNA and TGF-betal protein in renal biopsy specimens [from 1.59 +/- 0.35 to 0.96 +/- 0.27 and from (10.83 +/- 2.33) x l0(6) to (6.41 +/- 1.53) x 10(6), respectively; both P < 0.01], but in light microscopy the histological changes were similar to the first renal biopsy. Losartan was excellently tolerated in all patients in group A. No cases with losartan therapy showed too low blood pressure and other side effects.

CONCLUSIONThis study suggests that losartan have an effect on slowing progression of CAN. Reducing production of intrarenal TGF-betal may play a decisive role in the efficacy of losartan.
