Objective:To analyze the clinical effect and the preventive analysis of complications on the application of self-prescription soup for eliminating haemorrhoids after patients with moderate or severe hemorrhoids accepted surgery.Methods: 44 patients with moderate and severe hemorrhoids who once accepted operative treatment were divided into observation group and control group as random number table. The patients of control group received the treatment of hip bath by using potassium permanganate tablets, while the patients of observation group received the treatment of hip bath with fuming and washing by using self-prescription soup for eliminating haemorrhoids. The clinically curative effect, postoperative complication, pain, bleeding, edema, disappearance time of anal pendant expansion and healing time of wound between the two groups were compared and analyzed.Results: The total effective rate (100%) of the observation group was significantly better than that (77.27%)of the control group (x2=5.641,P<0.05). The cases of complication including pain, bleeding, constipation, infection, urinary retention and anal stenosis of observation group were significantly less than that of control group (t=7.333,t=15.655,t=5.500, t=4.247,t=8.193,t=5.500,P<0.05). Besides, the times of pain, bleeding, edema, disappearance of anal pendant expansion and wound healing of observation group were significantly, respectively, less than that of control group (t=3.171, t=5.864,t=4.263,t=6.219, t=10.803,P<0.05).Conclusion: The curative effect of self-prescription soup for eliminating haemorrhoids after patient with moderate or severe hemorrhoids accept surgery is significant, and it can effectively prevent and treat various complication.

BACKGROUND:Studies have shown that the finite element method could preferably simulate the biomechanical analysis for the object with complicated structures and irregular shapes. The similarities for the finite element model have great influences on the results of the analysis. However, to construct an ideal model is the most time-consuming and complicated portion for the finite element analysis. OBJECTIVE:To construct a finite element model for the maxilary first molar and the periodontal tissue, and to provide a basis of biomechanical researches of the maxilary first molar. METHODS: A volunteer with complete mandibular dentition and healthy periodontal tissue was selected in this study. Cone-beam CT was scanned. The images were saved as DICOM format. These images were imported to the medical modeling software Mimics. The surface model for the maxilary first molar and the alveolar bone was constructed. The model was then imported to GiD for pre-processing. Thus, the complete three-dimensional finite element model for the maxilary first molar and the periodontal tissue was constructed. RESULTS AND CONCLUSION:A finite element model for bilateral maxilary first molar, periodontal ligament and maxilary alveolar bone was constructed, including 896 035 nodes and 4 881 067 elements. This model has restored the geometric shape and the structure of the research object. This study successfuly constructed finite element models of maxilary first molar and the periodontal tissue, which can be a basis of biomechanical researches for the maxilary first molar and the periodontal tissue under the effect of different clinical orthodontic forces.

Objective To investigate the relationship between the plasma neutrophil gelatinase-associated lipocalin (NGAL)and endothelin-1 (ET-1) levels and cognitive dysfunction in chronic obstructive pulmonary disease (COPD) patients.Methods A case-control study was performed,consisting of 128 patients with COPD(68 patients without cognitive dysfunction and 60 patients with cognitive dysfunction) and 70 normal controls.All patients with COPD were diagnosed by pulmonary function tests and plasma levels of NGAL and ET-1 were determined by enzyme immunoassay.The cognitive function was evaluated by the MMSE and MoCA.Results ①Compared with normal control,the levels of plasma NGAL and ET-1 were increased(NGAL:(2.20±0.60) μg/L vs (1.69±0.73) μg/L,P＜0.05;ET-1:(26.19± 10.55)pg/ml vs (13.05±2.37) pg/ml,P＜0.05) in COPD patients without cognitive dysfunction and in COPD patients with cognitive dysfunction(NGAL:(3.80±2.75) μg/L vs (1.69±0.73) μg/L,P＜0.01;ET-1:(37.82±0.29) pg/ml vs (13.05±2.37) pg/ml,P＜0.01).Compared with the COPD patients without cognitive dysfunction,the levels of plasma NGAL and ET-1 were also increased in COPD patients with cognitive dysfunction (all P＜0.05).②The plasma NGAL levels were correlated negatively with MMSE scores(r=-0.524,P＜0.05),and negatively correlated with MoCA scores (r=-0.527,P＜0.05).The plasma ET-1 levels were negatively correlated with MMSE scores(r=-0.549,P＜0.05),and negatively correlated with MoCA scores(r=-0.558,P＜0.05).The levels of NGAL and ET-1 were positively correlated(r=0.564,P＜0.05).Conclusion NGAL and ET-1 may be involved in the pathophysiological process of cognitive dysfunction in patients with COPD,which provides a certain clinical value for the assessment of cognitive dysfunction in patients with COPD.

OBJECTIVE: To evaluate the protective effects of oral administration of D-methionine tablets on noise-induced hearing impairment. METHOD: Two hundred and three volunteers were recruited and randomly divided into two groups: experimental group (n= 113) and control group (n=90). The subjects received oral administration of D-methionine tablets in the experimental group and placebo in the control group before noise exposure. Routine audiometric evaluation and ABR testing were performed and recorded before and after noise exposure. The statistical analysis was carried out with SPSS 11.0. RESULT: There were no differences in auditory threshold and I-V interpeak latency pre-noise exposure (P>0.05), however, there were statistically significant differences between two groups 1 d, 7 d after noise exposure (P<0.01 and P<0.05). In-respective-group, there were statistically significant differences between before and 1 d after noise exposure (P<0.05 and P<0.01), however, no difference was noted between before and 7 d after noise exposure in the experimental group (P>0.05). CONCLUSION The protective effects of D-methionine tablets were prominent on the noise-induced hearing impairment. Further studies regarding the optimal time of D-methionine administration will be recommended in the future.

Objective:To explore the effect of therapeutic communication on infusion safety, disease uncertainty, coping styles, anxiety and depression in patients with emergency infusion.Methods:A total of 126 patients treated with infusion patients in emergency department in Jiangsu Provincial People's Hospital, the First Affiliated Hospital of Nanjing Medical University from July 2019 to December 2019 were selected and divided into two groups by random digits table method with 63 cases in each group. Patients in the control group received routine nursing, and patients in the intervention group received therapeutic communication nursing intervention on this basis. The incidence of adverse events of infusion during the intervention of the two groups of patients was observed. The disease uncertainty, coping styles, anxiety and depression were evaluated by Mishel's Uncertainty in Illness Scale (MUIS), Medical Coping Mode Questionnaire (MCMQ), Self-rating Anxiety Scale (SAS) and Self-rating Depressive Scale (SDS) before and after intervention.Results:The final collection of 109 patients with complete questionnaire, the recovery rate was 86.51% (109/126), including 55 cases in the intervention group, 54 cases in the control group. The incidence of adverse events of infusion was 16.36%(9/55) in the intervention group and 29.63%(16/54) in the control group, and there was significant difference( χ2 value was 5.057, P<0.05). There was no significant difference in the score of MUIS, MCMQ, SAS, SDS before the intervention between the two groups ( P>0.05). After the intervention, the uncertainty, unpredictability, lack of information and complexity dimension of the intervention group patients' MUIS scores were respectively (17.76 ± 2.49), (12.03 ± 2.51), (11.82 ± 2.12), (11.74 ± 2.24), which were lower than those in the control group (24.72 ± 2.94), (16.31 ± 2.27), (16.13 ± 2.51), (15.39 ± 2.31), the differences were significant( t values were -13.346- -8.375, P<0.05). The confront score of the intervention group patients' MCMQ was (19.13 ± 2.62) higher than that in the control group(13.79 ± 1.96), the avoidance and yield scores were respectively (8.71 ± 1.34), (9.81 ± 1.17), which were lower than those in the control group (14.57 ± 1.93), (15.12 ± 1.86), the differences were significant( t values were 12.031, -18.441, -17.875, P<0.05). The scores of SAS and SDS in the intervention group were (29.43 ± 3.62), (27.67 ± 3.11) respectively, which were lower than those in the control group (37.44 ± 5.31), (40.12 ± 4.92), the differences were significant( t values were -9.216, -15.821, P<0.05). Conclusions:Therapeutic communication can reduce the risk of emergency infusion, reduce the uncertainty of patients to the disease, improve patients' countermeasures to the disease, relieve patients' anxiety and depression, and improve the nursing quality of emergency infusion patients.

Objective To investigate the nature of Th17 cells in murine cytomegalovirus(MCMV)infection during the acute stage,we characterized the frequency of IL-17A-producing CD4 T cells and the level of Th17 cytokines,IL-17A,in MCMV-infected mice.Methods BALB/c mice were randomly divided into two groups.One was infected with MCMV Smith for establishing disseminative infection; the other was sham-inoculated control.On day 3,7,14 and 28 of the experiment,three mice of each group were randomly chosen to be killed separately.Real-time PCR was used to detect MCMV loads in organs of MCMV-infected mice,the pathology of spleen was observed by HE staining.The frequency of CD4+IL-17A+ T cells in total splenocytes of mice was detected by flow cytometry.The level of IL-17A in culture supernatants of splenocytes was measured by double antibody sandwich ELISA.Results MCMV loads in salivary gland reached the peak on day 14 after MCMV infection,the most severe spleen injury was also shown on day 14,the frequencies of CD4+IL-17A+ T cells in total splenocytes increased significantly( all P＜0.01 ) in MCMV-infected mice than those in controls,and reached the peak on day 14 ( 1.14％ ±0.09％ vs 0.19％ ±0.04％,t =17.551,P=0.000).The levels of MCMV-specific IL-17A in culture supernatants were increased dramatically in MCMV-infected mice than those in controls on day 14 [ (81.98± 12.37) pg/ml vs (44.96±8.44)pg/ml,t=4.281,P=0.006].In MCMV-infected mice,correlation was positive between the levels of MCMV-specific IL-17A in culture supernatants and MCMV loads in salivary gland tissues (r=0.54,P＜0.05 ),the levels of IL-17 A in culture supernatants were higher in more severe spleen injury.Conclusion Thl7 cells and IL-17A were involved in the immunity response during acute MCMV infection.They may correlate with the persistence of MCMV and the pathology of spleen in infected mice.

Objective To analyze the clinical features,treatment methods,and prognostic factors for early primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma.Methods A retrospective analysis was performed on the clinical data,treatment outcomes,and survival of 32 patients with early pulmonary MALT lymphoma from March 2001 to September 2013.The median age of those patients was 56 years.Twenty-three patients had stage ⅠE disease and nine had stage Ⅱ E disease.According to the marginal zone B-cell lymphoma prognostic index (MZLPI),twenty-three patients were scored as 0 and nine as 1.Nine patients received radiotherapy,eight patients underwent surgery alone,three patients underwent surgery plus chemotherapy,and twelve patients received chemotherapy alone.The Kaplan-Meier method was adapted for calculating the OS,PFS and the log-rank test was used for survival difference analysis and univariate prognostic analysis.Results The 5-year sample size was 22.The 5-year overall survival (OS) and progression-free survival (PFS) rates were 84.5％ and 73.2％,respectively.Radiotherapy yielded an overall response rate of 100％,including a complete response rate of 66.7％ and a partial response rate of 33.3％.The univariate analysis showed that non-radiotherapy treatment was a prognostic factor for poor PFS.The patients treated with radiotherapy had significantly higher 5-year PFS rates than those treated without radiotherapy (100％ vs.63.0％,P=0.029),while there was no significant difference in 5-year OS rate between these two groups (100％ vs.78.8％,P=0.129).Age older than 60 years,an ECOG score of 2,and an MZLPI score of 1 were prognostic factors for poor PFS (P=0.041,0.018,and 0.044) and OS (P=0.001,0.001,and 0.003).Conclusions The prognostic factors for early pulmonary MALT lymphoma include age,ECOG score,and MZLPI score.Low-dose involved-field radiotherapy (24-30 Gy) can improve local control and survival.

Objective To investigate the feasibility of the scheme of target volume delineation with extended involved?field intensity?modulated radiotherapy (IMRT) for patients with early?stage nasal NK/ T?cell lymphoma (NC?NKTL). Methods Twenty?one patients with stage IE?IIE NC?NKTL were treated with short?course chemotherapy combined with radiotherapy from 2011 to 2013. The majority of patients received the GELOX regimen. All patients received extended involved?field IMRT with a dose of 54?? 6 Gy in 26 fractions for gross tumor volume, 50?? 7 Gy in 26 fractions for high?risk clinical target volume (CTV), and 45?? 5 Gy in 26 fractions for low?risk CTV. The dose distribution, short?term treatment outcomes, and adverse reactions were analyzed. Results The 2?year sample size was 12. The 2?year follow?up rate was 100%. The 2?year local control rate ( LRC) was 100%. The 2?year overall and progression?free survival rates were 90?? 5% and 90?? 5%, respectively. The median coverage rates of planning target volumes with 90% of the prescribed doses of 54?? 6 Gy, 50?? 7 Gy, and 45?? 5 Gy were 99?? 8%, 99?? 6%, and 99?? 7%, respectively. No grade 3 or 4 adverse reactions were observed in patients. Conclusions The scheme of target volume delineation and dose configuration in our study not only achieves excellent target volume coverage, but also reduces adverse reactions in patients, which achieves a 2?year LRC ideal for patients with early?stage NC?NKTL.

ObjectiveTo observe the changes of AIM2 ( absent in melanoma 2) inflammasome during early murine cytomegalovirus (MCMV) infection.MethodsBALB/c mice were randomly divided into two groups.One was infected with MCMV Smith for establishing disseminated infection,the other was sham-inoculated control.On days 1,3,5 and 7 of the experiment,three mice of each group were randomly chosen to be killed separately.The expression of AIM2,ASC and caspase-1 in splenic macrophages was detected by Western blot,the levels of IL-1β and IL-18 in sera were measured by double antibody sandwich ELISA,and the viral titers in salivary gland tissues were quantified by a standard plaque assay.Results The MCMV titers in salivary gland tissues were gradually increased in MCMV-infected mice on days 3,5 and 7,while the expressions of AIM2 in macrophages were began to increase on day 1 and significantly increased and reached the highest level on day 3 but gradually decreased afterwards.The relative intensity of AIM2 on day 3 differed significantly between the MCMV-infected mice and the controls (1.121±0.243 vs 0.240±0.046,P＜0.01,t test),as did ASC ( 1.318±0.333 vs 0.248±0.090,P＜0.01 ) and caspase-1 ( 1.085±0.243 vs 0.247±0.064,P＜0.01 ).Meanwhile,the levels of IL-1β and IL-18 in MCMV-infected mice were (112.72±5.20) pg/ml and (42.74±4.23) pg/ml,and the levels were significantly higher (P＜0.01 ) than those in controls [ (47.86±4.35) pg/ml and (22.60±2.82) pg/ml].ConclusionThese results demonstrate that AIM2 inflammasome is activated in macrophages during early MCMV infection and could be as a therapeutic target for CMV-induced diseases.

Objective To explore the correlation between the expression of IL-17A and the degree of spleen damage in acute mouse cytomegalovirus(MCMV) disseminated infection in vivo and to understand the mechanism about how IL-17A involved in the pathological damage of the spleen in MCMV infection.Methods An acute disseminated MCMV infection model was established in mice.BALB/c mice were randomly divided into two groups.Mice in group one were infected with MCMV Smith to establish disseminated infection.Mice in another group were sham-infected control.Three mice from each group were randomly chosen to be sacrificed on days 3,7,14 and 28 after the infection.Viral titers in spleen tissues were determined using a standard plaque assay.The expression of IL-17A mRNA and MCMV mRNA in the splenocytes were measured by RT-PCR.The expression of IL-17A in spleen tissues was observed by immunohistochemical staining.The pathology of the infected mice was assessed by histological examination of H&E stained spleen sections.Results Viral titers and MCMV mRNA in the spleen peaked on day 3,but quickly diminished on day 7.Virus was no longer detectable in the spleen on day 14 after the infection.The expression of IL-17A mRNA was significantly increased during the acute infection and reached the highest level on day 14,then decreased on day 28.It is significantly higher than that of the mock infection group.Immunohistochemistry assay also indicated that the expression of IL-17A in spleen tissue gradually increased to climax on day 14,then decreased on day 28.Accordingly,the pathological damages of spleen tissue in the infected mice deteriorated until day 14,then showed signs of recovery on day 28.The most severe pathological injury of spleen tissue and the highest expression of IL-17A appeared in the same period of time.Conclusion Our results showed a close correlation between IL-17A and the pathological damage in spleen.Thus,IL-17A may contribute to the spleen pathological damage during the acute disseminated MCMV infection.
