ABSTRACT
Objective:To investigate the application of 3.0T multiparametric magnetic resonance imaging (Mp-MRI) prostate imaging-reporting and data system (PI-RADS) V2.1 score combined with prostate-specific antigen density (PSAD) in the diagnosis of prostate cancer (PCa).Methods:The clinical data of 82 patients with suspected PCa who were admitted to Nantong Second People's Hospital from May 2017 to Octorber 2021 were retrospectively analyzed. The 3.0T Mp-MRI PI-RADS V2.1 score, serum PSAD level and pathological diagnosis were obtained from all patients. The 3.0T Mp-MRI PI-RADS V2.1 score and its distribution as well as serum PSAD level between patients with pathologically diagnosed PCa and patients with prostatic hyperplasia (BPH) were compared. The diagnostic efficiency of 3.0T Mp-MRI PI-RADS V2.1 score and serum PSAD level alone and in combination for PCa was analyzed using receiver operating characteristic (ROC) curve, with pathological results as the gold standard.Results:Pathological diagnosis showed that there were 43 cases (52.44%) of PCa and 39 cases (47.56%) of BPH. There was a statistical difference in the distribution of 3.0T Mp-MRI PI-RADS V2.1 score between PCa and BPH patients ( Z = 32.25, P<0.001). The 3.0T Mp-MRI PI-RADS V2.1 score of PCa patients was higher than that of BPH patients [(4.29±0.25) points vs. (2.24±0.11) points, P < 0.001], the serum PSAD level was higher than that of BPH patients [(0.49±0.15) ng·ml -1·cm -3 vs. (0.27±0.08) ng·ml -1·cm -3, P < 0.001]. The ROC curve analysis showed that area under the curve of 3.0T Mp-MRI PI-RADS V2.1 score, serum PSAD level alone and both together for the diagnosis of PCa were 0.766 (95% CI 0.659-0.852, P < 0.001), 0.793 (95% CI 0.689- 0.874, P < 0.001) and 0.816 (95% CI 0.715-0.893, P < 0.001). Conclusions:3.0T Mp-MRI PI-RADS V2.1 score and serum PSAD level are both elevated in PCa patients. They have certain values in the diagnosis of PCa, and the combination of the two has higher diagnostic efficiency.
ABSTRACT
ObjectiveTo observe the effects of specific exercise therapy on spinal deformity and joint hypermobility of idiopathic scoliosis. MethodsFrom April to October, 2021, 100 children with idiopathic scoliosis in the Scoliosis Rehabilitation Center of Xinhua Hospital were divided into control group (n = 50) and experimental group (n = 50), who accepted routine exercise therapy or scoliosis-specific exercise therapy in accordance with their wishes, for six months. The maximum Cobb angle and bone mineral density were measured, and they were assessed with Beighton Scale and Chinese version of the Scoliosis Research Society-22 Questionnaire Scores (SRS-22) before and after treatment. ResultsThe change of the maximum Cobb angle was more in the experimental group than in the control group (Z = -2.202, P < 0.05) after treatment, and the incidence of respondent was more (χ2 = -2.405, P < 0.05). The bone mineral density decreased in the experimental group after treatment (|Z| > 2.127, P < 0.05). For SRS-22, the total scores increased in both groups after treatment (Ftime = 106.57, P < 0.001), and increased more in the experimental group than in the control group (F = 4.969, P < 0.05); the scores of function domain and self-image domain increased in the experimental group (|Z| > 2.149, P < 0.05), while the mental health domain score decreased in the control group (Z = -2.096, P < 0.05); and the mental health domain score was more in the experimental group than in the control group (Z = -2.260, P < 0.05). ConclusionThe scoliosis-specific exercise therapy is effective on spinal deformity and quality of life for children with idiopathic scoliosis, but less helpful for joint hypermobility and bone mineral density, which need to further improve.
ABSTRACT
OBJECTIVE:To provide references for rational use of human serum albumin.METHODS:The inpatients receiving human serum albumin in the hospital during Jan.-Dec.2014 were investigated retrospectively and analyzed in respects of general information of patients,serum albumin level before medication,drug dosage,drug cost and reasons.RESULTS:Eight thousand seven hundred and sixty patients from top 8 departments in the list of the number of patients of human serum albumin were included in the study,accounting for 64％ of total.There were 5 244 male (59.9％) and 3 516 female (40.1％);patient's age mainly ranged ＞ 30-60 year-old (52.6％).The number of patients of albumin was the largest in general surgery department (2 588 cases) and cardio vascular surgery department (2 348 cases).Referring to domestic package inserts,8 210 patients (about 93.7％) were in accor dance with indications,and hypoproteinemia was the most common medication indication (35.6 ％).The drug dosage per capita of ICU was the highest (152.5 g);total drug cost was the highest in general surgery department (13 334 396.4 yuan);treatment course per capita of infection disease department was the longest (10.7 d).CONCLUSION:There is irrational use of human serum albumin in our hospital and difference of drug use among departments.It is necessary to strengthen human serum albumin use monitoring and establish rational medication evaluation system so as to promote standard drug use and realize rational distribution of medical resources.
ABSTRACT

ABSTRACT
Objective To explore the relationship between plasma interleukin-11(sIL-11) level and platelet count post-chemotherapy with hematological malignancy patients and analyse a sIL-11 level which may maintain a safe platelet count so as to guide the treatment. Methods Blood samples were collected from the patients with hematological malignancy at certain time point of pre-and post-chemotherapy, and serum level of sIL-11 and platelet count were determined separately. Different statistical methods were applied to test the relationship between sIL-11 level and platelet changes. Results 99 cases finished this study. The findings are: the sIL-11 level went up and reached the peak on day 6 post-chemotherapy, while the platelet count kept dropping to the lowest on day 10, the sIL-11 peak occurred before the lowest platelet count, patients with faster sIL-11 increase may maintain a comparatively higher plateled count. 99 eases were grouped according to the lowest platelet count and compared: the group with higher platelet count tend to have higher peak sIL-11, more cases with higher peak sIL-11, with faster daily average sIL-11 increase, the lowest platelet count occurred later. Logistic regression analysis showed the factors contributed to lower platelet includes slower daily average sIL-11 increase and sIL-11 level less than 2000 pg/ml on Day4 post-chemotherapy. Conclusion There were correlation between the serum sIL-11 level and platelet counts, the platelet count change may be predicted by determining the plasma sIL-11 level post-chemotherapy. Patients with sIL-11 level less than 2000 pg/ml on Day4 post-chemotherapy may be endangered with severe thrombocytopenia, rhIL-11 or platelet transfusion treatment should be considered.
ABSTRACT
Objective:To study the dynamic distribution of BaP in the corpus striatum by r-counting and light microscopic autoradiography,then to explore the neurotoxic mechanism of BaP.Methods:100 SD male rats were divided into control group(n=40)and test group(n=60),experimental animals were given a single intravenous injection of 3.7?105 Bq/kg of 14CBaP while the same doses of Normal Saline were given to the control group.The rats were sacrificed at 1h,1 d,2 d,3 d and 7 d after the administration of radiolabelled BaP.During the experiment,some toxicological symptoms were observed and the ratios of brain-weight/body-weight were detected.Light microscopic autoradiography and r-counting were used to observe the dynamic distribution of BaP in the corpus striatum.Results:The change of toxicological symptoms are observed and the decrease ratios of brain-weight/body-weight are detected.R-counting shows that the percentage dose/g of 14CBaP in striatum is significant higher than in hippocampus and cortex at 1d and 2 d after administration.Light microscopic autoradiography shows that the silver granules in striatum reach the peak in 1d and sharp decrease in 2 d,which can be found even at 7d.Conclusion:BaP can penetrate the blood-brain barrier and distribute in corpus striatum,inducing CNS toxicity in SD rat.
