RESUMO
Objective:To investigate the etiology, clinical manifestations, clinicopathological features of cystic neutrophil granulomatous mastitis (CNGM).Methods:From Jan 2019 to Dec 2020, 95 CNGM cases diagnosed by biopsy pathology at Chongqing Hospital of Traditional Chinese Medicine and Chongqing Liangping District Hospitol of Traditional Chinese Medicine were reviewed.Results:There were 95 female patients, aged 21 to 50 years, with a median age of 32 years. Laboratory examination showed that 56% (53/95) cases had elevated rheumatoid antibody level, 27 % (26/95) had increased level of serum thyroid antibody, 15% (14/95) had elevated antineutrophil antibody, 35% (33/95) had increased ESR, 38% (36/95) had increased C-reactive protein. The positive rate of Gram-stained bacilli was 82% (78/95). Histology: pyogenic granuloma with lobule of breast as the center, the center of granuloma was cystic vacuole.Immunohistochemistry showed that the inflammatory cells in and around granuloma were mainly CD3 + cells, and CD4 + cells were more than CD8 + cells. Conclusions:The cystic neutrophilie granulo matous mastitis is a rare type of idiopathic granulomatous mastitis. The diagnosis of CNGM is dependent on its specific pathological features.
RESUMO
Objective: To observe the efficacy and safety of microwave ablation (MWA) in treatment of secondary hyperparathyroidism (SHPT) ineligible for surgical resection. Methods: Clinical data of 51 patients with SHPT ineligible for surgical resection who underwent MWA were retrospectively analyzed. The maximum diameter of single proliferative nodule, serum intact parathyroid hormone (iPTH), calcium and phosphorus were assessed and compared before and after ablation. The complications, local recurrence rate and new incidence rate were counted during follow-up. Results: Totally 83 parathyroid hyperplasia nodules in 51 SHPT patients were completely ablated at one time. Three, 6 months after MWA and at the end of the follow-up, the maximum diameter of single proliferative nodule was all smaller than that before MWA (all P<0.05), and serum iPTH, calcium, and phosphorus levels were all lower than that before MWA (all P<0.05). During follow-up, 9 patients (9/51, 17.65%) had minor complications related to MWA, while no serious complication occurred. At the end of follow-up, the local recurrence rate was 5.88% (3/51) and the new incidence rate was 7.84% (4/51). Conclusion: MWA is safe and effective in treatment of SHPT ineligible for surgical resection.
RESUMO
Objective To investigate the clinical and pathological diagnosis of cutaneous calcifying epithelioma.Methods Thirty cases of calcified epithelioma were diagnosed and treated by our hospital.The clinical features and pathological features were retrospectively reviewed.Results The main pathological features of the tumor were that the main tumor (basophilic cells) basal cells and shadow cells were mixed composition,combined with ossification and calcification and with no recurrence after surgical resection.Conclusion The clinical manifestations of calcifying epithelium are lack of characteristics and diverse pathological features.It is necessary to make the correct pathological diagnosis with the time,location and imaging of tumor growth.
RESUMO
Objective To investigate the effect of immune modulation therapy on heart function and cytokines in elder patients with chronic heart failure (CHF). Methods The 96 patients aged 60-78 years with New York Heart Association(NYHA)functional. class Ⅱ-Ⅳ CHF were randomly divided into two groups: CHF treatment group received regular therapy and thymopetidum and CHF control group received regular therapy. Another 45 healthy individuals aged 60-80 years were involved as normal control. The ejection faction of left ventricle (LVEF), inflammatory cytokines including tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β), anti-inflammatory cytokine interleukin-10 (IL-10), plasma high sensitive C-reactive protein (hsCRP), plasma brain natrium peptide (BNP)and Minnesota Living with Heart Failure Questionnaire (LHFQ) assessment were tested before therapy, 15 days and 75 days after treatment. Results (1) Before therapy, compared with normal control group, the levels of TNF-α, IL-1β, TNF-α/IL-10 ratio, BNP, hsCRP and LHFQ were significantly increased (P ＜ 0. 05 or P ＜ 0. 01 ), and the levels of IL-10, LVEF were markedly decreased (P＜0.01) in the patients of CHF treatment group and CHF control group. While no difference between the two CHF groups was observed. (2) After the first course of treatment,compared with CHF control group, the levels of IL-10 were increased (P＜0. 01), while the levels of TNF-α, IL-1β, BNP and hsCRP were decreased (P＜0.05 or P＜0.01) in CHF treatment group. The level of LVEF was increased, TNF-α/IL-10 ratio (4.84 ±0. 53 vs. 5.28±0. 66) and LHFQ were decreased even though there was no significant difference between the two groups. (3) After the second course of treatment, compared with CHF control group, the levels of IL-10 and LVEF were increased (P＜0. 05 or P＜0.01), while the level of TNF-α, IL-1β, TNF-α/IL-10 ratio (4.55±0. 69 vs. 5.18±0.38), BNP, hsCRP and LHFQ were decreased (P＜0.05 or P＜0.01) in CHF treatment group. Conclusions Thymopetidum, as an immunemodulating agent, might regulate the equilibrium of cytokines and improve the heart function of patients with CHF, indicating that immune modulation therapy might improve the treatment strategy for CHF patients.
RESUMO
Objective To examine the expression levels of α1-adrenergie receptor(α1-AR)and angiotensinⅡ reeeptor(ATR)subtypes in left ventricle of rats from adolescent age, middle age,presenium to senium. Methods Semiquantitative reverse transcription polymerase chain reaction (RT-PCR) was used to quantitate the messenger RNA (mRNA) of α1-AR and ATR subtypes in left ventricle in Wistar rats aged 3-months (adolescent age), 12-months (middle age), 18-months (presenium) and 24-months (senium). Results The expression of α1A-AR mRNA was decreased gradually with aging, and the gene expression of α1 D-AR was repressed in middle age and presenium,while the expression of a,B-AR mRNA remained unchanged during senescence. Cardiac AT1R expression was not affected by aging from adolescent age to presenium, but exhibited a remarkable up-regulation in senium There was no significant discrepancies of cardiac AT2R expression among the four different age groups. Conclusions The results suggest that there are considerable changes in mRNA levels of cardiac α1-AR and ATR subtypes with aging. The change of cardiac α1-AR and ATR expression during aging is a protective response for senescence and has an important significance in maintaining normal physiological functions of heart.
