Objective To explore the clinical efficacy of tension-free vaginal tape obturator inside-outside(TVT-O)in the treatment of female stress urinary incontinence.Methods In this study,we enrolled the patients with stress urinary incontinence who were treated with TVT-O(n=72)or midodrine hydrochloride(n=72).The patient self-evaluation and the Results of pad test and urodynamic test 6 and 24 months after the treatment were compared.Results These 2 kinds of treatment significantly improved the symptoms in patients with stress urinary incontinence,and in patients treated with TVT-O the clinical efficacy 24 months after the treatment was better.Conclusion TVT-O is safe and effective in treating female stress urinary incontinence,and the long-term follow-up and the improvement of urodynamic indices show it is better than simple drug treatment.

Sera were collccted from mice immunized separately with schizonts, merozoitcs or different parasite stages, or from mice which had been recovered from Plasmodium yoelii yoelii infection. The effect of protection of cach serum against P. y. infection was assayed by passivc transfer technique. It was shown that only sera collected from mice which either had been trcated with chloroquine or had been naturally recovcred from P. y. infections can transfer certain dcgree of resistance to normal mice. The cffectivc sera delayed the appearance and the peak of parasitemia, and prolonged the survival time of the challenged mice. After these sera were fractionatcd by 50%(NH4)2SO4 precipitation, the prccipitated fraction showed similar degree of protection as the non-fractionated sera. Chloroquine-treated serum was shown to be able to inhibit the invasion of new erythrocytes by marozoite in vitro. 35S-methionine-labelcd antigens were precipitated by protective or non-protective sera and the bands were compared on SDS-PAGE and autoradiogram. Since thc antigcn bands of 245, 210, 190, 156 and 130 KD can only bc precipitated by protective sera but not by non-protectivc sera, it is possible that the protection of chloroquine-treated serum is induced by the specific antibodies against the above antigens.

BACKGROUND: Tongxinluo acts on benefiting qi, promoting circulation in collateral, activating blood circulation and resolving stasis, which is well effective in treatment of ischemic cerebral vascular disease. Single-photon emission computed tomography (SPECT) provides reliable reference evidence objectively and sensitively for clinical evaluation of therapeutic effects.OBJECTIVE: SPECT and clinical neurofunctional defect score (NDS)were used to observe the therapeutic effect of tongxinluo capsule on cerebral infarction.DESIGN: Case analysis was designed.SETTING: Internal Department of Neurology of First Affiliated Hospital of Chongqing Medical University.PARTICIPANTS: Totally 22 cases of acute cerebral infarction were admitted in Internal Department of Neurology of First Affiliated Hospital of Chongqing Medical University from March 2002 and July 2003, in which 12 cases were male and 10 cases were female, aged varied from 40 to 78 years, sick duration in range from 3 hours to 3 days.METHODS: Voluntarily, 22 cases of acute cerebral infarction were randomized in tongxinluo capsule group (capsule group)(11 cases) and the control (11 cases). In the control, danshen tablet was administrated,4 tablet/time, 3 times/d. In capsule group, tongxinluo capsule group was administrated, 4 pills/time, 3 times/d. The drugs were administrated for 15 days in two groups. Before and after treatment, SPECT ROI technique was used to assay ROI average radioactive counts on the affected and healthy sides to understand local blood flowing volume of brain in two groups. Neurofunctional defect evaluation was done before and after treatment on each patient.in two groups.RESULTS: Totally 22 cases of cerebral infarction all entered result analcontrol after treatment [(49.182±5.344 5), (28.364±4.610 3) score P ＜ 0.001].the affected side of the control and treatment group before treatment was decreased. Fifteen days after treatment, the volume in original decreased flowing area of brain was improved after taking the capsule (66.536±18.676,ter administration of the capsule reflected in SPECT radionuclide, but it was not improved remarkably in the control.CONCLUSION: Tongxinluo capsule improves definitely cerebral blood flow in patients with cerebral infarction. With improvement of blood flowing in brain, the neurofunctional defect score is promoted clinically, too. It is explained that the capsule promotes the recovery of nerve function.

Objective To investigate the role of p38 mitogen-activated protein kinase (MAPK) signal transduction pathway in lipopolysaccharide (LPS)-induced acute lung injury (ALI).Methods Sixty male SD rats weighing 180-230 g were randomly divided into 4 groups: control group (group C, n = 6), ALI group ( n = 24),p38MAPK specific inhibitor SB203580 + ALI group (group SB + ALI, n = 24), SB203580 group (group SB,n =6). LPS 5 mg/kg was injected intravenously via tail vein in group ALI and SB + ALI, while the equal volume of normal saline was given instead in group C. Group SB + ALI received iv injection of SB203580 10 mg/kg via tail vein 30 min before LPS administration. Group SB received injection of SB203580. The rats were sacrificed at 1, 3 and6 h agter LPS administration (T1-3) in group ALI and SB + ALI (8 rats at each time point) andat 1 h after administration in C and SB groups. The lungs were immediately removed for microscopic examination and determination of phosphorylated p38MAPK (p-p38MAPK) expression, the concentration of protein in bronchoalveolar lavage fluid (BALF) and apoptotic index (AI). Another 32 rats were selected and randomly divided into 2 groups for survival study: ALI group and SB + ALI group ( n = 16 each), and then they were treated as mentioned above and observed for 48 h. Results The concentration of protein in BALF, AI and p-p38MAPK expression were significantly increased in group ALI and SB + ALI compared with group C, while decreased in group SB + ALI compared with group ALI ( P ＜ 0. 05 ). LPS-induced pulmonary histological changes were significantly attenuated in group SB + ALI compared with group ALI. The survival rate was significantly decreased in group ALI compgred with group SB + ALI ( P ＜ 0.01 ). Conclusion p38 MAPK signal transduction pathway is involved in LPS-induced ALI, which may be related to the apoptosis in the cells in the lung.

Objective To explore the clinical effects of high frequency oscillatory ventilation (HFOV) combined with pulmonary surfactant (PS) on neonatal meconium aspiration syndrome (MAS).Methods Data of 53 newborns with MAS admitted into the Neonatal Intensive Care Unit of Ning Bo Women and Children's Hospital from June 2008 to June 2011 were retrospectively analyzed.According to different therapeutic measures,they were divided into three groups:conventional mechanical ventilation (CMV) group (n=23),HFOV group (n=18) and HFOV+PS group (n=12).The oxygen index,arterial oxygen/alveolar oxygen ratio (a/ApO2) and inspired oxygen fraction (FiO2) were monitored at 2,12,24 and 48 h after mechanical ventilation.The mechanical ventilation time,duration of hospital stay,change of symptom,complications and clinical outcomes of the three groups were compared by analysis of variance and Chi-square test.Results The parameters of the three groups at 2 and 48 h after mechanical ventilation were as followed:CMV group [oxygen index:(23.79±7.27) and (15.04±4.76) mm Hg; a/ApO2:0.11±0.04 and 0.31 ±0.07; FiO2:0.74±0.16 and 0.47± 0.21],HFOV group [oxygen index:(21.13±6.29) and (11.73±4.54) mm Hg; a/ApO2:0.14±0.06 and 0.35±0.06; FiO2:0.68±0.14 and 0.41±0.11] and HFOV+ PS group [oxygen index:( 18.35 ± 5.68 ) and ( 7.85 ± 5.06 )mm Hg; a/ApO2:0.17±0.03 and 0.40±0.02; FiO2:0.59±0.13 and 0.29±0.16].Compared with CMV group,the parameters of HFOV group and HFOV+ PS group were different at different time points,and the parameters (duration and extent) of HFOV+ PS group were better than those of HFOV group (all P＜0.05).The mechanical ventilation time was (7.2±0.6) days in CMV group,(4.2± 1.4) days in HFOV group and (2.9±0.5) days in HFOV+PS group; the hospital stay was (22.2±4.5) days in CMV group,(15.6±3.4) days in HFOV group and (11.8±4.3) days in HFOV+PS group; and the oxygen treatment time was (15.4± 2.4) days in CMV group,(11.8±5.3) days in HFOV group and (7.4±2.2) days in HFOV+PS group.The mechanical ventilation time,oxygen treatment time and hospital stay time were the longest in CMV group,the shortest in HFOV+ PS group (P＜ 0.05,respectively).Conclusions Early HFOV combined with PS might be a better therapeutic method for infants with MAS than HFOV or CMV alone.

Objective To study the mechanisms of increasing amyloid [β1-42 (Aβ42) level by presenilin-1 (PS-1) mutation of V97L.Methods Expression level of neprilysin (NEP) in nontransfected, or mock vector, wild type (wt) PS-1 and V97L-PS-1-transfected SH-SY5Y cells were assessed by reverse transcriptional-polymerase chain reaction (RT-PCR) and Western blot.The level of Aβ42 was also assessed by enzyme linked immunosorbent assay (ELISA).Results The mRNA level of NEP was decreased significantly in PS-1 V97L transfected cells (0.650 ± 0.010) compared to that in normal cells (1.090 ± 0.015), wt PS-1 gene (1.040 ± 0.021) and mock (1.080 ± 0.020) stably transfected cell lines (t = 9.236, 10.452, 5.678; all P < 0.01).Although there was a decreased tendency in the protein expression of NEP in PS-Ⅰ V97L transfected cells (1.000 ± 0.126)compared to that in normal cells (1.020 ± 0.110), wt PS-1 gene (1.040 ±0.110), mock (2.130 ±0.130) stably transfected cell lines, nosignificant differences were found.The expression of Aβ42 was increased significantly in PS-1 V97L transfected cells compared to other cell lines (t = 2.109, 3.355, 3.976; all P < 0.01).Conclusions PS-1 V97L mutation can decrease the transcription of NEP, however, in contrast, this mutation also resulted in increased Aβ42.The mechanism needs further analysis.
