RESUMO
Objective@#To study the incidence and clinicopathological features of intermediate fibroblastic/myofibroblastic tumors(IF/MFT) in infants and the young children.@*Methods@#All available cases with soft tissue tumors in infants and children were retrieved from the files of Women and Children′s Hospital Affiliated to Qingdao University, from January 2012 to December 2017.The incidence rate of IF/MFT was observed.Cases of IF/MFT were identified and investigated by light microscopy and immunohistochemistry by reviewing the related literature.@*Results@#Among 290 soft tissue tumors, 15 cases(5.2%) were IF/MFT, accounted for 88.2%(15/17 cases) of borderline soft tissue tumors.Twelve cases were male, 3 cases were female, the median age was 8 months, and 4 cases were congenital.Clinically, 11 cases were presented with slow-growing painless masses located in the trunk or extremities.According to histopathology, 9 cases(60.0%) were categorized as infantile fibromatosis(IFM), including 5 cases(33.3%) desmoid-type and 4 cases(26.7%) diffuse-type; 3 cases(20.0%) as lipofibromatosis(LFM); 2 cases(13.3%) as infantile fibrosarcoma(IFS) and 1 case(6.7%) as giant cell fibroblastoma(GCF). All 15 tumors were characterized by the presence of spindle fibroblasts and myofibroblasts with infiltration of the surrounding structures.Immunohistochemically, all the 15 cases were diffusely positive for Vimentin(Vim), but negative for Myogenin, MyoD1, Desmin and S-100.Smooth muscle actin(SMA), β-catenin and Bcl-2 were positive in some cases to a certain degree.The Ki-67 proliferation index was higher in diffuse-type IFM and IFS, the former was 5.0%-20.0%, and the latter was about 20.0%, however, the other cases showed Ki-67 <5.0%.The main clinical treatment was complete or extensive excision.@*Conclusions@#IF/MFT accounts for a high proportion of intermediate soft tissue tumors in infants and young children, mostly seen in male children, and IFM and LFM are the main types.The clinical signs and symptoms associated with these tumors are often nonspecific, and their histopathologic manifestations may overlap.The final diagnosis of IF/MFT must depend on the characteristics of age, location, histopathologic changes and immunohistoche-mical findings.
RESUMO
Objective To compare two different methods to detect the differences of gene mutation rate, sensitivity, specificity and coincidence rate of epidermal growth factor receptor (EGFR) in non-small-cell lung cancer (NSCLC) so as to assess the clinical value of qRT-PCR method and its environmental-friendly technologyplatforms.One uses environmental fixative poly hydroxyl acrylic acid and green transparent liquid dewaxing Van-clear alone or in combination to replace the traditional fixative 4％ (volume fraction) neutral buffered formalin and the traditional transparent dewaxing liquid xylene in application of quantitative real-time polymerase chain reaction (qRT-PCR).The other uses traditional reagents in direct sequencing.Methods We selected 91 cases of primary NSCLC specimens resected between May 2013 and March 2016 in Zhongshan Bo`ai Hospital and Zhongshan Hospital of Traditional Chinese Medicine.Five samples were taken from the same tumor lesion.We used a random number table to randomly divide these samples into Groups A, B , C, D, and E.Group A received direct sequencing method in detection of EGFR gene mutations.Besides, during the experiment, 4％ neutral buffered formalin was used for fixing, and xylene transparent dewaxing was used to make slices for DNA extraction dewaxing.Group B received qRT-PCR method to detect EGFR gene mutations.Meanwhile, during the experiment, 4％ neutral buffered formalin was used for fixing, and xylene transparent dewaxing was used to make slices for DNA extraction dewaxing.Group C received qRT-PCR method in detection of EGFR gene mutations.At the same time, during the experiment, polyhydroxy acrylic acid was used for fixing, and xylene transparent dewaxing was used to make slices for DNA extraction dewaxing.Group D received qRT-PCR method to detect EGFR gene mutations.In the meantime, 4％ neutral buffered formalin was used for fixing, Van-clear transparent dewaxing was used to make slices for DNA extraction dewaxing.Group E received qRT-PCR method in detection of EGFR gene mutations.In addition, during the experiment, polyhydroxy acrylic acid was used for fixing, and Van-clear transparent dewaxing was used to make slices for DNA extraction dewaxing.In addition, during the experiment, polyhydroxy acrylic acid was used for fixing, and Van-clear transparent dewaxing was used to make slices for DNA extraction dewaxing.The mutations of Exons 18, 19, 20, and 21 in EGFR genes were respectively determined in the five groups of NSCLC.Results ① Groups B, C, D, E and A did not significantly differ in the percentage of people with mutations or target site mutation rates of EGFR genes in NSCLC (P> 0.05).② The detection results of EGFR target site mutation in Groups B, C, D, E and A had good sensitivity, strong specificity, and high compliance rate.Conclusion The green transparent liquid dewaxing Van-clear alone or in combination to replace the traditional fixative 4％ neutral buffered formalin and the traditional transparent dewaxing liquid xylene in the application of qRT-PCR so as to detect EGFR gene mutations in NSCLC has good consistent results compared with the method that uses traditional reagents in direct sequencing.It has the significance and value in clinical application.

Objective To investigate the clinical efficacy of three yin points acupuncture plus medicinal spreading moxibustion in treating erectile dysfunction.Methods Sixty patients with erectile dysfunction meeting the inclusion criteria were randomly allocated to two groups, 30 cases each. The control group took sildenafil at 1 hr before sexual intercourse. The treatment group received three yin points acupuncture plus medicinal spreading moxibustion, 8 days as one course of treatment, for three consecutive courses with 2 days of rest between the courses. The erectile function was scored in the two groups before and after treatment. The clinical therapeutic effects were compared.Results The total efficacy rate was 93.3% in the treatment group and 80.0% in the control group; there was no statistically significant difference between the two groups (P>0.05). The marked efficacy rate was 83.3% in the treatmentn group and 60.0% in the control group; there was a statistically significant difference between the two groups (P0.05).Conclusions Both acupuncture-moxibustion and sildenafil have a therapeutic effect on erectiledysfunction. Sildenafil produces a rapid and stable effect. Acupuncture and moxibustion produce a slower effect but have an advantage in the marked efficacy rate. Acupuncture and moxibustion are safe, of fewer contraindications and suitable for most of the population.
RESUMO
Background and purpose: Adequate tissue ifxation, transparent dewaxing is an important step of hematoxylin eosin (HE) staining and lfuorescence in situ hybridization (FISH) in detection of breast cancerHER-2 gene. The purpose of this study was to make a comparison between poly hydroxyl acrylic acid which is an environmen-tally friendly ifxation liquid and 4% neutral buffered formaldehyde in tissue ifxation for HE staining and FISH to detect theHER-2 gene in the breast cancer tissue sections. The study aimed to evaluate the feasibility of replacing 4% buffered formaldehyde, a traditional ifxation liquid, with the poly hydroxyl acrylic acid, an environmentally friendly ifxation lfuid.Methods:This project was performed on tissue samples collected from 69 cases of breast cancer, 41 cases of breast ifbroadenoma, 40 cases of uterine leiomyoma, 25 cases of cervical tissue, 25 cases of placenta obtained from the outpatient and inpatient departments of Zhongshan Boai Hospital from Mar. 2011 to Jan. 2015, from each of which two samples were drawn and two blocks of each specimen were divided into two groups randomly. Then one group was ifxed with 4% neutral buffered formaldehyde and made into 200 sections by HE while the other group was ifxed with poly hydroxyl acrylic acid and made into another 200 sections. The slice level of the two groups was determined by the staining condition of the sections, and SPSS 19.0 was employed to compare the excellent and good rate of HE staining. Additional 69 sections were produced with two groups of breast invasive ductal carcinoma tissues, and SPSS 19.0 was used to detect the ampliifcation ofHER-2 gene by FISH.Results:First, the number of best-quality slices stained with HE ifxed separately by poly hydroxyl acrylic acid and 4% neutral buffered formaldehyde was 155 and 166, respectively. The number of excellent pieces was 41 and 33, respectively, while the number of mediocre pieces was 3 and 1 with bad pieces being 1 and 0, respectively. The excellent and good rates of HE staining were 98% and 99.5%, respectively. There was no significant difference between the two groups (χ2=1.33,P>0.05).Second, the positive rates of the tis-sue slices by FISH ifxed separately by poly hydroxyl acrylic acid and 4% neutral buffered were 26.09% and 23.19%, respectively. There was no signiifcant difference between the two groups (χ2=0.50,P>0.05).Conclusion:The results obtained with HE staining and FISH using poly hydroxyl acrylic acid as a ifxation liquid are not signiifcantly different from those using 10% neutral buffered formaldehyde. Therefore, poly hydroxyl acrylic acid meets the requirements of environmental protection, and thus has the potential to be promoted and widely used.
