To discuss the ethical factors influencing the standard diagnosis and treatment of sexual transmitted diseases(STDs) on special population including senile patients,pregnant and lying-in women and children.The senile patients with STDs had a decline of physiological function and might have foundational diseases,some of these patients had the psychological characteristics such as unclear talk,uncertain memory,stronger self-esteem,and had a decline of life quality.Therefore hte main ethical measures during the senile patients with STDs should include considering the pathophysiological and psychological characteristics,adopting individual diagnosis and treatment,making the skill of inquiring and physical examination,and attaching importance to the improvement of life quality.The main ethical measures during the pregnant and lying-in women with STDs should include attaching importance to the marriage examination and pregnant examination,finding potential STDs as soon as possible,and weighing potential medical risk.The main ethical measures during the children with STDs should include paying attention to the infection of family members or sex-aggression,making the protective medicine,doing well the propaganda and education,and making the children away from STDs.

Objective To investigate effect of carnosine on oxygen glucose deprivation/reperfusion ( OGD/RP) induced injury in rat brain slices. Methods Injury of brain slices was determined by TTC methods.The contents of ATP, ADP and AMP were determined by high performance liquid chromatography.Reactive Oxygen species ( ROS) were determined by fluorescence methods.Results Compared with control group, rat hippocampal slices were significantly damaged by OGD/RP, indicated by light color and decreased A490 nm value of TTC staining.Meanwhile the contents of ATP and ADP were significantly decreased, and the content of AMP and ROS were significantly increased, the difference between two group was significant ( P<0.01).Pre-incubation with Carnosine (1000, 200, 40 μg/mL) significantly inhibited the light color and decreased A490 nm value of TTC staining, increased the contents of ATP, ADP and AMP, and decreased the content of ROS, the difference between two group was significant ( P <0.01 ) . Conclusion Carnosine can protect rat hippocampal slices against injury induced by OGD/RP, which may relate to improve the energy metabolism and strengthen the ability of anti-oxidative stress.

ObjectiveTo investigate the status of job satisfaction and the influencing factors of the disabled in order to know their employment quality.Methods79 disabled employees of one company in Hunan province were randomly interviewed with Minnesota Satisfaction Questionnaire.ResultsThe overall satisfaction scores of 74 disabled workers was 67.78, which inner satisfaction was better than external satisfaction. The most satisfied was job independence and colleagues' relationships and the most unsatisfied was work flexibility and conditions. There were statistically significant differences between gender, age, disabled species and job satisfaction. In personal level, most influencing factors of disabled job satisfaction were gender, age, disability and salary types.ConclusionVocational rehabilitation such as the high-risk population could be performed specifically on the basis of the job satisfaction survey.

Background Retinal microglia (RMG) plays an important role in the pathogenesis of retinal degenerative diseases,while chemokine CX3CL1 participates in the regulation of steady-state of microglia.It has been determined that bone marrow-derived mesenchymal stem cells (BMSCs) have a remarkable role to modulate the immune response and protect the central nervous system through the release of soluble factors in a paracrine fashion and further affect the functional behavior of cells.However,whether BMSCs are able to interact with RMG and activate related signaling pathway for the maintaining of homeostasis in the retina is still unclear.Objective The aim of this study was to investigate the interaction between BMSCs and lipopolysaccharide (LPS)-activated RMG in vitro,and dissect the effects of CX3CL1/CX3CR1 signaling pathway on the biological behavior of BMSCs and RMG.Methods RMG was isolated from SD rats,cultured with mixed culture of retinal glial cells and purified by shaking.The cells were identified by detecting the expression of CD111b,Iba1 and glutamamine synthetase (GS) with indirect immunofluorescence assay.LPS (1 mg/ml,2 μl) was added in the medium for 24 hours to stimulate RMG,and then the cells were divided into LPS control group,BMSCs group (cocultured with BMSCs for 24 hours) and CB-BMSCs group (cocultured with CX3CL1-blocking-BMSCs for 24 hours).The cells without LPS stimulation served as the blank control group.The functions of RMG,including the release content of tumor necrosis factor-α (TNF-α) and interleukin-1 β (IL-1β),the proliferation,phagocytosis,and migration of RMG were examined.Results RMG was successfully isolated and harvested from SD rats by using mixed culture of retinal glial cells and purified by shaking.CD11b and Iba1 showed the positive expression with the green fluorescence in the cells and GS was absent.The contents of TNF-αt in the cell supernatant were (2.55 ±0.97) ng/ml,(24.91 ±3.07) ng/ml,(20.38 ±2.97) ng/ml and (24.90 ± 1.88) ng/ml in the blank control group,LPS control group,BMSCs group and CB-BMSCs group,respectively,showing a significant difference among the groups (F=119.90,P＜0.05).The contents of IL-1 β in the cell supernatant were (1.12±0.36) ng/ml,(10.40±2.76) ng/ml,(7.00± 1.75) ng/ml and (9.55 ± 1.11) ng/ml in the blank control group,LPS control group,BMSCs group and CB-BMSCs group,respectively,showing a significant difference among the groups(F =34.96,P＜0.05).The secretory volume of TNF-α and IL-1 β were evidently lower in the BMSCs group than those in the LPS control group (both at P＜0.05),and no significant differences were found in the secretory volume of TNF-α and IL-1β between CB-BMSCs group and LPS control group (both at P＞0.05).The proliferative rate of RMG was lower in the BMSCs group than that in the LPS control group (P＜0.05),while there was no statistical difference between BMSCs group and CB-BMSCs group (P＞0.05).The mean fluorescence intensity (MFI) and the number of migrated RMG were considerably different among the four groups (F=70.55,15.49,both at P＜0.05),and those in the BMSCs group were significantly increased in comparison with the LPS control group (both at P＜0.05),while there was no significant difference between CB-BMSCs group and LPS control group (both at P＞0.05).Conclusions BMSCs could suppress the proliferation of LPS-activated RMG.Moreover,BMSCs might inhibit proinflammatory cytokines releasing,enhance phagocytosis and migration capabilities of RMG via CX3CL1/CX3CR1 signaling pathway.

Background Laser peripheral iridoplasty (LPI) is widely used in the treatment of glaucoma by flattening the iris and widening angle of anterior chamber (AA).However,no evidence suggests the optimal site of LPI in iris.Objective This study was to compare the therapeutic effects of LPI at different sites of iris for glaucoma.Methods Glaucoma models were established in the right eyes of 40 healthy adult male pigment rabbits by intrachamber injection of 0.1 ml compound carbomer solution with 0.3％ carbomer and 0.025％ dexamethasone.The models were randomly divided into model control group,corneoscleral limbus group,one spot from corneoscleral limbus group and two spots from corneoscleral limbus group.LPI was performed at corresponding site of iris by 532 nm argon laser with the spot diameter 500 μm,energy 300 mW,exposure time 0.3 seconds and laser number 24 spots,and the rabbits in the model control group did not receive LPI.Intraocular pressure (IOP),coefficient of outflow facility (C value) were measured and calculated with Schi(o)tz tonometer before LPI and 2,4,7,14 and 30 days after LPI,and anterior chamber depth (ACD),AA,anterior chamber angle opening distance within 500 μm radius from scleral spur (AOD500) were measured with ultrasound biomicroscope (UBM).The eyeballs were extracted 30 days after LPI,and the chamber angle were observed under the optical microscope after hematoxylin and eosin staining.The use and care of the animals complied with the Guide for the Care and Use of Laboratory Animals of the National Institutes of Health.Results UBM showed that compared with the model control group,the anterior chamber angle was evidently widened in all the LPI groups,with the best effectiveness in the one spot from corneoscleral limbus group and the worst one in the two spots from corneoscleral limbus group.Compared with the model control group,the IOP was evidently reduced,and C values,AA and AOD500 were significantly increased in the corneoscleral limbus group,one spot from corneoscleral limbus group and two spots from corneoscleral limbus group after LPI,showing significant differences among the four groups (IOP:Fgroup =16.848,P ＜ 0.01;C value:Fgroup =9.629,P ＜ 0.01;AA:Fgroup =62.336,P＜0.01;AOD500:Fgroup =77.779,P ＜ 0.01).IOP was reduced and C value,AA and AOD500 were increased in 2,4,7,14 and 30 days after LPI as compared with before LPI,with significant differences over time (IOP:Ftime =3.041,P =0.011;C value:Ftime =4.311,P＜0.01;AA:Ftime =14.627,P＜0.01;AOD500:Ftime =20.378,P＜0.01).Compared with the model control group,the ACD was significantly increased in the corneoscleral limbus group and one spot from corneoscleral limbus group,and that in the two spots from corneoscleral limbus group was significantly reduced,and the ACD was insignificantly increased over time after LPI (Fgroup =18.017,P＜0.01;Ftime =0.022,P =1.000).Hematoxylin and eosin staining showed that the trabecular meshwork and adhesion of tissure were reopened and the anterior chamber angle was widened after LPI.Conclusions LPI can widen anterior chamber angle and lower the IOP.The best therapeutic outcome for glaucoma is displayed when LPI is performed at the iris site corresponding to one spot from the corneoscleral limbus.

Objective To investigate the extracellular polysaccharide distribution and components of Ureaplasma urealyticum (Uu) after biofilm having been developed in.Methods The standard serotype 3 and serotype 14 belong to biovar Parvo,and the standard serotype 4 and serotype 8 belong to biovar T960 were employed to form biofilrns in vitro.Scanning electron microscope and confocal laser scanning microscope were used to analysis the biofilms and extracellular polysaccharide.We used combination of two different labeled lectins,Canavalia ensiformis(FITC-ConA) and Erythrina cristagalli(ECA) which bind to specific polysaccharide residues to visualize extracellular polysaccharide in biofilms,and average uorescence intensity was evaluated Results All the strains can form the biofilmsin vitro.The biofilm was honeycomb-Like structures mainly,and extracellular polymeric substances accounts for majority of proportions.All the extracellular polysaccharide could be combined with FITC-ConA and ECA,and the total average fluorescence intensity of FITC-ConA was higher than ECA( P＜0.001 ).Conclusion Ureaplasma urealyticum biofilm is honeycomb-like structures mainly.The extracellular polysaccharide contains,galactose,and N-acetyl glucan residual,and the glucose,mannose residual are the main components.

Objective:To investigate the effect of soft channel minimally invasive treatment on hypertensive intracerebral hemorrhage (HICH) and its influence on serum interleukin-18 (IL-18), vascular endothelial growth factor (VEGF), C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α).Methods:From April 2017 to April 2019, 82 patients with HICH admitted to Taizhou Hospital of Traditional Chinese Medicine were randomly divided into observation group (41 cases) and control group (41 cases) according to random number table method.The control group was treated with hard channel minimally invasive treatment, while the observation group was treated with soft channel minimally invasive treatment.The therapeutic effect, intracranial hematoma volume, serum levels of IL-18, VEGF, CRP and TNF-α before and 7 days after operation, neurological deficit degree (NIHSS) scores before and 3 months after operation, and complications after operation were compared between the two groups.Results:The total effective rate of the observation group (92.68%) was higher than that of the control group (70.73%) (χ 2=6.609, P<0.05). The amount of intracranial hematoma in the observation group [(4.03±1.10)mL] was lower than that in the control group [(7.17±1.36)mL] ( t=11.495, P<0.05). At 7 d after operation, the serum levels of IL-18[(123.74±10.27)ng/L], VEGF[(113.28±12.10)ng/L], CRP[(17.83±3.20)mg/L] and TNF-α[(0.65±0.12)ng/L] in the observation group were lower than those in the control group [(150.38±13.21)ng/L, (141.63±16.87)ng/L, (29.96±4.53)mg/L and (1.09±0.17)ng/L] ( t=11.638, 9.101, 13.831, 5.569, all P<0.05). The NIHSS score of the observation group[(16.53±3.19)points] was lower than that of the control group[(23.43±4.65)points] at 3 months after operation ( t=7.824, P<0.05). The incidence of complications in the observation group (12.20%) was lower than that in the control group (34.15%) (χ 2=5.549, P<0.05). Conclusion:Soft channel minimally invasive treatment for HICH has good effect and can reduce the changes of serum levels of IL-18, VEGF, CRP and TNF-α.
