Objective:To assess the differences among the expressions of p38 mitogen activated protein kinases (MAPK),phospho-p38MAPK and nuclear factor kappa B (NF-κB)in oral lichen planus (OLP)and oral squamous cell carcinoma (OSCC ).Methods:In the study,53 cases of OLP,45 of OSCC,and 18 controls were obtained and 4-μm-thick histological sections were prepared from formalin-fixed paraffin-embedded tissue blocks.The expressions of p38MAPK,phospho-p38MAPK and NF-κB were detected by immunohistochemistry staining.Furthermore,the expressions of p38MAPK and phospho-p38MAPK were detected using Western blotting analyses in the fresh tissues from 1 1 cases of OLP,5 ca-ses of OSCC,and 7 cases of the controls.Results:p38MAPK was over-expressed in the lamina propria, but lowly expressed in the epithelium in OLP group.Phospho-p38MAPK was lower expressed in OLP group than in OSCC and control groups.NF-κB was found over-expressed in the lamina propria in OLP group.p38MAPK was found expressed in all the samples in the 3 groups.The expression of phospho-p38MAPK was observed in 8 (8/11)OLP samples,5 (5/5)OSCC samples and 4 (4/7)controls by Western blotting,but no significant differences were found within the 3 groups.Conclusion:p38MAPK can be detected in normal oral mucosa,OLP and OSCC.phospho-p38MAPK may be related to the onset and progression of OSCC.The role of p38MAPK in OLP is yet to be revealed.

Objective To compare the effectiveness of medicated γintrauterine device (IUD) and medicated genefix IUD inserted immediately after abortion. Methods A multicenter clinical trail was performed for the study from Mar. 2012 to Jan. 2013. Totally 840 women who volunteered to participate were randomly allocated to γ-group (medicated γ IUD) or genefix-group (medicated genefix IUD) immediately after abortion. While 464 abortion women who had not used IUD or steroids contraceptive methods were chosen as control group. The effectiveness of the IUD were followed up for 1 year. All women were required to record the number of vaginal bleeding days and blood volume of vaginal bleeding within 3 months after abortion. Results At the 12th month, the expulsion was the most common reason for termination. The expulsion rates of genefix-group and γ-group were 2.48/100 women years and 3.12/100 women years, respectively (P>0.05). For the expulsion reasons, IUD moving down could account for more than seventy percent. The removal rate for IUD usage of two IUD groups were almost equal (3.91/100 women years verus 4.35/100 women years), the differences were not statistically significant (P>0.05). At the 90th day after abortion, comparing with control group, the bleeding and (or) spotting days of genefix-group and γ-group extended by 3.9 and 2.6 days respectively, the differences had statistical significance between the three groups (P<0.05). Among the bleeding and (or) spotting days, spotting days prolonged significantly. At the 12th month, spotting days of genefix-group andγ-group were (9.2±5.9) days and (8.5±4.6) days respectively, more than (5.2 ± 4.0) days of control group. The differences had statistical significance between IUD with control group (P<0.05), and had not between the two kinds of IUD (P>0.05). Conclusion The insertion of medicated genefix IUD and medicated γ IUD immediately after abortion is safe, feasible, has slight side effects and could be effective contraception.

Objective To investigate the curriculum construction and evaluation of teaching effectiveness of simulation and comprehensive experiment for clinical nursing. Methods Based on the investigation of hospital, taking working progress and working task of nurses as orientation, we constructed the curriculum of simulation and comprehensive experiment for clinical nursing, and unfold in junior class (before clinical practice) for student nurses. The teaching effect was evaluated. Results Unfolding simulation and comprehensive experiment could effectively enhance the nursing students' ability to transform theoretical knowledge into clinical nursing practice, and was favorable to change the role of nurses and improve the satisfaction degree of clinical practice.Conclusions Unfolding simulation and comprehensive experiment for clinical nursing for student nurses before clinical practice is practicable and essential.

Objective:To investigate the expression of retinoic acid receptor responsive gene 2 (RARRES2), microtubule microfilament cross-linking factor 1 (MACF1), and core protein polysaccharide (DCN) in cerebrospinal fluid (CSF) of patients with neurosyphilis, and their diagnostic value for neurosyphilis.Methods:A total of 64 non neurosyphilis syphilis patients (syphilis group) and 78 neurosyphilis patients (neurosyphilis group) admitted to the Second Hospital of Nanjing between June 2020 and September 2022 were included. Among neurosyphilis patients, there were 48 early neurosyphilis patients (early group) and 30 late neurosyphilis patients (late group). Patients with neurosyphilis are treated with routine symptomatic therapy and antibiotic therapy to expel syphilis. The mRNA levels of RARRES2, MACF1, and DCN in CSF of patients with neurosyphilis before and after treatment were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the neurological function of patients with neurosyphilis before and after treatment. The diagnostic value of various indicators for neurosyphilis was analyzed using receiver operating characteristic (ROC) curves.Results:The mRNA levels of RARRES2, MACF1, and DCN in CSF of patients with neurosyphilis were higher than those in the syphilis group (all P<0.001). The mRNA levels of RARRES2, MACF1, and DCN in the CSF of patients with advanced neurosyphilis were higher than those in the early group (all P<0.001). Compared with before treatment, the NIHSS score and RARRES2, MACF1, and DCN mRNA levels of neurosyphilis patients decreased after treatment (all P<0.001). The area under the curve (AUC), sensitivity, and specificity of the combined diagnosis of RARRES2, MACF1, and DCN mRNA in CSF for neurosyphilis were 0.995%, 100.00%, and 93.75%, respectively. The AUC and sensitivity were higher than those of individual diagnosis. Conclusions:The expression of RARRES2, MACF1, and DCN is elevated in CSF of patients with neurosyphilis, and is associated with disease severity and treatment response. These three genes may be candidate biomarkers for diagnosing neurosyphilis.
