Objective To investigate the effects of cognitive interventions (CIs) in the context of communi- ty based rehabilitation (CBR) on cognitive deficits (CDs) in stroke patients.Methods Ninety-two stoke patients with CDs were randomly divided into a CI group and a control group.All patients were treated with conventional CBR.In addition,the patients in the CI group were also treated with special intervention therapy.The patients in both groups were assessed with the neurological and cognitive status examination (NCSE) for cognitive functioning, the FCA for motor function and the BI for their ability in the activities of daily living.Results The NCSE,FCA and BI scores in the cognitive intervention group after treatment were significantly higher than those before treatment and also significantly higher than those in the control group after treatment.Conclusion CIs can not only improve CDs,but also enhance recovery of motor function and ADL.

OBJECTIVETo study the effects of NS398, a selective cyclooxygenase-2 (COX-2) inhibitor, on the transcription and translation of BCL-3 and its regulatory gene cyclin D1 in colon cancer cell line SW480.

METHODSHuman colon cancer cells SW480 were divided into two groups: SW480 cells in experimental group were treated with NS398 in different concentrations(25 micromol/L, 50 micromol/L, 100 micromol/L and 200 micromol/L) for 48 h or 72 h. SW480 cells in control group were treated with media which did not contain NS398. Then the expressions of BCL-3 and cyclin D1 were detected by RT-PCR, Western blot, and immunocytochemistry.

RESULTSAt 48 hours RT-PCR showed that BCL-3 mRNA and cyclin D1 mRNA decreased in a dose-dependent manner in the experimental group. However, there were no significant differences in the levels of BCL-3 protein and cyclin D1 protein between two groups (P>0.05). At 72 hours, BCL-3 protein and cyclin D1 protein also decreased in a dose-dependent manner in the experimental group. When the concentration of NS398 reached 100 micromol/L, the differences between the two groups in the expression of BCL-3 mRNA and protein became statistically significant (P<0.01). When the concentration of NS398 reached 50 micromol/L, the differences in the expression of cyclin D1 mRNA and protein were statistically significant (P<0.05).

CONCLUSIONSBCL-3 is expressed in colon cancer cell line SW480. COX-2 inhibitor can inhibit the expression of BCL-3 and cyclin D1 in a dose-dependent manner. NS398 may down-regulate the expression of cyclin D1 through BCL-3.

To discover novel antitumor rhodanine unsaturated ketones, a series of fluoroquinolone (rhodanine α, β-unsaturated ketone) amine derivatives (5a-5r) were designed and synthesized with fluoroquinolone amide scaffold as a carrier. The structures of eighteen title compounds were characterized by elemental analysis, 1H NMR and MS. The in vitro anti-proliferative activity against Hep-3B, Capan-1 and HL60 cells was evaluated by MTT assay. The results showed that the title compounds not only had more significant anti-proliferative activity against three tested cancer cell lines than that of the parent ciprofloxacin 1, but also exhibited the highest activity against Capan-1 cells. The SAR revealed that some compounds carrying aromatic heterocyclic rings or phenyl attached to an electron-withdrawing carboxyl or sulfonamide substituent were comparable to or better than comparison doxorubicin against Capan-1 cells. As such, it suggests that fluoroquinolone (rhodanine α, β-unsaturated ketone) amines are promising leads for the development of novel antitumor fluoroquinolones or rhodanine analogues.

To discover novel antitumor fluoroquinolone lead compounds from a rational modification for antibacterial fluoroquinolones, a fused heterocyclic ketone corresponding to thiazolo[2,3- b][1,2,4]triazolone used as a bioisosteric replacement of the C-3 carboxylic acid group of ciprofloxacin 1, and further modification by a Claisen condensation reaction with substituted benzaldehydes formed novel fluoroquinolone C-3 fuse heterocyclic α, β-unsaturated ketones as the title compounds (6a-6r), separately. The structures of eighteen title compounds were characterized by elemental analysis, 1H NMR and MS, and the in vitro anti-proliferative activity against human hepatoma Hep-3B cells, pancreatic Capan-1 cells and leukemia HL60 cells was evaluated by a MTT assay. The preliminary results showed that the title compounds not only had more significant anti-proliferative activity against three tested cancer cell lines than that of the parent ciprofloxacin 1, but also exhibited the highest activity against Capan-1 cells. In particular, compounds carrying an electron-withdrawing carboxyl (6k, 6m) or sulfonamide substituent (6q, 6r) attached to benzene ring were comparable to or better than constractive drug doxorubicin against Capan-1 cells. As such, it suggests that it is favorable for a fused heterocyclic α, β-unsaturated ketone scaffold instead of the C-3 carboxylic acid group to improve the antitumor activity of fluoroquinolones.

PURPOSETo investigate the clinical significance and management of ASCUS/LSIL.

METHODS254 patients who were examined with cervical cytology in the Cancer Institute and Hospital Chinese Academy of Medical Sciences were ASCUS/LSIL, of whom 136 cases underwent colposcopy, Data were analyzed retrospectively according to the golden criterion of pathology outcome.

RESULTS140 cases were ASCUS, and 114 cases were LSIL. Cervical intra-epithelial neoplasia (CIN) were diagnosed in 51.5% of patients with ASCUS, compared with 59.6% of patients with LSIL (P>0.05). High-grade cervical intraepithelial neoplasia were diagnosed in 22.9% of patients with ASCUS, compared with 30.7% of patients with LSIL (P >0.05). In the 136 patients examined with colposcopy, inflammation was found in 47 cases, low-grade intraepithelial lesion in 53 cases, High-grade intraepithelial lesion in 36 cases. The pathological results show inflammation in 55 cases, low-grade intraepithelial lesion in 41 cases, High-grade intraepithelial lesion in 40 cases (Kappa=0.314, U=0.064, P less than 0.05). CIN were diagnosed in 79% (67/84) of HPV-positive patients identified by pathology, compared with 43.5% (74/170) of HPV-negative patients (chi2=29.88 P less than 0.05). 83.5% of 254 patients were between 35 to 55 years old, and that was consistent with HPV-positive women age peak.

CONCLUSIONPatients with ASCUS should be paid the same attention with LSIL patients and colposcopy examination should be done immediately to avoid missed diagnosis and missed follow-up examination, especially for HPV positive patients between 35 to 55 years old.

Low birth weight (LBW) and preterm birth (PB) are associated with newborn mortality and diseases in adulthood.We explored factors related to LBW and PB by conducting a population-based case-control study from January 2011 to December 2013 in Wuhan,China.A total of 337 LBW newborn babies,472 PB babies,and 708 babies with normal birth weights and born from term pregnancies were included in this study.Information of newborns and their parents was collected by trained investigators using questionnaires and referring to medical records.Univariate and logistic regression analyses with the stepwise selection method were used to determine the associations of related factors with LBW and PB.Results showed that maternal hypertension (OR=6.78,95％ CI:2.27-20.29,P=0.001),maternal high-risk pregnancy (OR=1.53,95％ CI:1.06-2.21,P=0.022),and maternal fruit intake ≥300 g per day during the first trimester (OR=1.70,95％ CI:1.17-2.45,P=0.005) were associated with LBW.BMI ≥24 kg/m2 of mother prior to delivery (OR=0.48,95％ CI:0.32-0.74,P=0.001) and gestation ≥37 weeks (OR=0.01,95％ CI:0.00-0.02,P＜0.034) were protective factors for LBW.Maternal hypertension (OR=3.36,95％ CI:1.26-8.98,P=0.016),maternal high-risk pregnancy (OR=4.38,95％ CI:3.26-5.88,P＜0.001),maternal meal intake of only twice per day (OR=1.88,95％ CI:1.10-3.20,P=0.021),and mother liking food with lots of aginomoto and salt (OR=1.60,95％ CI:1.02-2.51,P=0.040) were risk factors for PB.BMI ≥24 kg/m2 of mother prior to delivery (OR=0.66,95％ CI:0.47-0.93,P=0.018),distance of house from road ≥36 meters (OR=0.72,95％ CI:0.53-0.97,P=0.028),and living in rural area (OR=0.60,95％ CI:0.37-0.99,P=0.047) were protective factors for PB.Our study demonstrated some risk factors and protective factors for LBW and PB,and provided valuable information for the prevention of the conditions among newborns.

OBJECTIVETo study the relationship between substance P (SP) and/or calcitonin gene-related peptide (CGRP) immunoreactive neurons in dorsal root ganglia (DRG) and the transmission of nociception in the penile frenulum of rats.

METHODSThe fluoro-gold (FG) retrograde tracing method was used to trace the origin of nerve terminals in the penile frenulum of rats. And SP and/or CGRP immunofluorescence labeling was employed to detect the distribution of SP and/or CGRP immunoreactive neurons in DRG.

RESULTSFG retrograde tracing showed that the FG retrolabeled neurons were localized in L6-DRG and S1-DRG. SP and/or CGRP immunofluorescence labeling indicated that a large number of DRG neurons were SP- and CGRP-immunoreactive, different in size, bright red and bright green respectively in color, and arranged in rows or spots among nerve bundles. All the FG/SP and FG/CGRP double-labeled neurons were medium or small-sized. One third of the FG-labeled neurons were SP-immunoreactive, and a half of them CGRP-immunoreactive in L6-DRG and S1-DRG respectively. The FG/SP/CGRP-labeled neurons accounted for one fifth of the FG retro labeled neurons.

CONCLUSIONSP- and CGRP-immunoreactive neurons in L6-DRG and SI-DRG of rats may be involved in the transmission of nociception in rat penile frenulum.

OBJECTIVETo compare data from an epidemiological survey on injuries with a survey conducted in hospitals on injuries in the same areas and to find out the differences and shortcomings of hospital data in describing the feature of injuries in an area.

METHODSComparing the causes and age distributions of injuries from the two surveys.

RESULTSThe first 4 leading causes of injuries from the population-based survey were mechanical injuries, falls, burns/scalds and traffic accidents while the first 4 leading causes of hospital-based survey were traffic accidents, assault, mechanical injuries and burns/scalds. The differences of the age distributions of these leading causes between the two surveys were significant except mechanical injuries.

CONCLUSIONDifferences were noticed between population-based survey and hospital-based survey. It should be cautions when using hospital data to describe the features of injuries in a certain area.
