Objective To investigate the clinicopathologic characteristics,therapy and prognostic factors of small cell carcinoma of the cervix.Methods Clinical and pathological data of eight patients were analyzed retrospectively.Results Eight patients all presented with symptoms of abnormal vaginal bleeding or postcoital spotting.One patient had stage Ⅰ b1 disease,2 had stage Ⅰ b2 disease.2 had stage Ⅱ b disease and 3 had stage Ⅲ b disease.Histopathologic findings showed the small tumor cells had scant cytoplasm,round nuclei,absence of nucleoli,and finely dispersed chromatin.Immunohistochemical findings were positive in 7 cases for neuron-specific enolase.Three patients with stage Ⅰ b disease and 1patient with stage Ⅲb disease underwent radical hysterectomy and postoperative chemotherapy.with or without radiotherapy,and the survival period was 64,22,14 and 6 months respectively.Two patients with stage Ⅱ b disease and 2 with stage Ⅲ b disease underwent chemotherapy and radiotherapy,and the survival period was 25,9,10 and 5 months respectively.Conclusions Immunohistochemical analysis using several kinds of neuroendocrine markers is helpful in establishing the correct diagnosis in addition to focusing on characteristic histopathological features.It is necessary to use comprehensive treatment including surgery,chemotherapy and radiotherapy for patients with small cell carcinoma of the cervix.Chemotherapy may play an important role in the treatment.

Objective To study the expressions of Hepcidin,bone morphogenetic protein 6 (BMP6) and hemojuvelin (HJV) in gastric cancer,and to explore their relationships with clinical pathological characteristics.Methods Hepcidin,BMP6 and HJV were detected by immunohistochemistry in 62 cases of gastric cancer patients,and the relationships among them and clinical pathological features were analyzed.Results Compared with normal gastric mucosa tissues,Hepcidin was highly expressed in gastric cancer tissues (13.3％ vs.56.5％,x2 =8.99,P ＜ 0.01),while the differences of the expression of BMP6 and HJV in the two groups were not statistically significant (60.0％ vs.40.3 ％,x2 =1.89,P ＞ 0.05;93.3％ vs.83.9％,x2 =0.88,P ＞ 0.05).The expression of Hepcidin was related to T stage (x2 =6.98,P =0.02),but it was not related to age,sex,lymph node metastasis,distant metastasis and anemia.The expressions of BMP6 and HJV were not related to T stage,age,sex,lymph node metastasis,distant metastasis and anemia.Hepcidin was not related to the expressions of BMP6 and HJV (r=0.13,P＞0.05;r=0.15,P＞0.05).Conclusion Hepcidin is highly expressed in gastric cancer tissues,which is related to the T staging of gastric cancer,and can be used as an objective indicator of the biological behavior of gastric cancer.There were no differences in the expression of BMP6 and HJV between normal gastric mucosa and gastric cancer tissues.

Aim To iuvestigate the effect and the mechanism of salmonmilt DNA (SMD) on age-related involutions in mouse thymus. MethodsFemale BALB/c of 10 months were divided randomly into three groupsaccording to their weights: high dosage group 333.33 mg/(kg @ d), lowdosage group 166. 67 mg/(kg @ d) and control group 0 mg/(kg @ d) .After five weeks, with Image-Pro Plus (version. 4.0) software, the thymusindexes and the thymoctytes in the thymus section were measured, as wellas the thymus cortex thickness. All the data were analyzed by SAS statisticsoftware. Mieroarray technique was applied to screen the gene fragments,which were differently expressed between the high dosage group and thecontrol group, together with RT-PCR to further confirm some of them.Results No significant differences of the variables including bodyweight, thymus weight and thymus indexes among the three groups werefound (F ＜ 3.0 and P ＞ 0.05, respectively). The thymocytes quanti-ties of thymus cortex and medulla in the high dosage group were significantlyhigher than those of the control group [cortex D(H, C) = 9.46, P ＜ 0.01;medulla t( H.C) = 2.53, P ＜ 0.05]. The thymus cortex thicknesses of bothSMD supplement groups were significantly higher than that of the control group[cortex D(L,C)=3.65, P＞ 0.05; medulla t(L, C)=0.8, P＞ 0.05] .112differently expressed gene fragments were isolated. Furthermore, we foundthe fragments with the logged number of U23789, X80232 and Aw209102were highly expressed in the high dosage group when RT-PCR techniquewas used. Conclusion SMD may reverse the age-related involutions inmouse thymus via up-regulation the expression of proliferation related genesand development and differentiation related genes simultaneously.

Objective To study the relationship between serum erythropoietin(Epo)level and chemotherapy-induced hemoglobin(Hb)level in elderly patients with cancer. Methods　One hundred senile patients(aged≥60 years)with cancer and one hundred and seventy non-senile patients(aged＜60 years)with cancer were selected as aged group and control group,respectively.The serum Epo level was detected by enzyme-linked immunosorbent assay(ELISA). Results　(1)The average levels of the serum Epo in aged group and control group were(22.0±15.1)U/L and(30.4±21.8)U/L,respectively(t=1.2988,P＞0.05).A negative correlation was found between the levels of Epo and Hb in elder cancer patients(r=0.3700,P＜0.001).(2)The levels of serum Epo were(14.7±10.6)U/L,(20.2±9.0)U/L and(42.3±24.8)U/L in 55 cases with normal Hb level,22 cases with mild anemia and 23 cases with moderate to severe anemia,respectively(F=11.6886,P＜0.01).(3)The levels of Epo were(20.2±10.8)U/L,(45.2±39.1)U/L and(25.8±15.9)U/L before chemotherapy,after 4 treatment cycles and 2 treatment cycles respectively(F=4.5477,P＜0.01).The levels of Hb were(111.0±20.5)g/L,(96.8±16.6)g/L and(102.1±19.3)g/L before chemotherapy,after 4 treatment cycles and 2 treatment cycles respectively(F=4.0071,P＜0.01).Conelusions　There is no statistical difference in serum Epo level between senile patients with cancer and non-senile patients with cancer.but serum Epo levelis higher in patients with anemia than without anemia.There is a negative correlation between the levels of Epo and Hb.Chemotherapy can decrease the level of Hb and increase the serum 1evel of Epo in part of patients.The changes are correlated with the conditions of patients before chemotherapy and the time of chemotherapy.

Background: Acute mastitis is an acute infectious disease of breast. Antibiotic treatment is often unable to obtain a good effect, and we should actively look for a safe and effective non-drug therapy. Objective: To validate the clinical efficacy of kneading and dispersing manipulation in treatment of early-stage acute mastitis. Design, setting, participants and interventions: According to the multicenter randomized controlled trial design, 198 cases of acute mastitis from Yueyang Hospital of Integrated Traditional Chinese Medicine, Longhua Hospital, and Shanghai Yangpu Maternity and Child Health Hospital were randomly divided into treatment group and control group. There were 99 cases in each group. Patients in the treatment group were only treated with manipulation, and cefradine was orally administered to patients in the control group. Main outcome measures: The local breast lump size, clinical symptoms and the adverse reactions in the two groups were observed before and after the treatment. Results: The total response rates in the treatment and control group were 95.92% (94/98) and 80% (76/95) respectively. There was a significant difference in the total response rate between the two groups (P<0.05). There were significant differences in the score of breast lump size, and the score of signs and symptoms between the two groups (P<0.05). Conclusion: Kneading and dispersing manipulation has certain effects on early-stage acute mastitis, and the therapy is safe and repeatable.

AIM: The study was designed to explore the autoimmune mechanism of myocardial injury and ventricular remodeling after acute myocardial infarction (AMI). METHODS: An experimental animal model of AMI was adopted in Wistar rats. After 6 weeks, splenocytes were freshly transferred to syngeneic inbred rats. Four weeks later, these recipient rats were anesthetized for hemodynamics analysis by catheter technique. Serum antibody against cardiac myosin heavy chanin (MHC) was screened by ELISA. Histopathological studies were performed on all hearts. The phenotypes of T lymphocytes in myocardium were analyzed by histocytochemistry stain. RESULTS: Histopathological studies showed the lymphocytes infiltration in non-infarction myocardium in AMI rats and the organ specific inflammation of myocardium in all succedent recipient (AMI-T) rats. Histocytochemistry stain revealed the predominant CD4+T cells infiltration in myocardium. The antibody against MHC was examined in 8/22 cases of AMI rats and AMI-T rats, but none in sham-T rats. The left ventricular dysfunction was found in AMI-T rats, which was characterized by slight decline of ~+dp/dt_~max. CONCLUSIONS: The study showed inflammatory response of non-infarction myocardium in AMI rats and demonstrated the lymphocytes-mediated myocardial injury and cardiac dysfunction by adoptive transfer of splenocytes of AMI rats. The autoimmune-mediated myocardial injury might be a novel mechanism of ventricular remodeling after AMI. [

To investigate the clinicopathological features of endometrial endometrioid adenocarcinoma(EEA)with adnexal involvement.Methods The clinicopathological data of 86 EEA patients who underwent surgical treatment at our center from January 2000 to December 2015 were analyzed retrospectively.The clinicopathological features were compared between patients with occult adnexal involvement and those with gross adnexal involvement.Results A total of 86 EEA patients with adnexal involvement(mean age:58.1 years)were included in this study,accounting for 5.4%(86/1592)of the EEA patients during the same period.Among these 86 patients,there were 13 premenopausal patients(15.1%)including 2 premenopausal patients aged under 40 years.Gross adnexal involvement was found in 47 patients(54.7%),while occult adnexal involvement was found in 39 patients(45.3%)in pathology evaluation.Ovarian metastasis was found in 34 patients(39.5%),followed by both ovarian and tubal metastasis in 19 patients(22.1%)and tubal metastasis in 33 patients(38.4%).The expressionss of estrogen receptor(χ=8.086,P=0.042)and progesterone receptor(PR)(χ=9.149,P=0.026)were significantly different between gross adnexal involvement group and occult adnexal involvement group,whereas no significant difference was found in other clinicopathological features(all P>0.05).The non-conditional Logistic regression analysis showed that,compared with PR no-expression group,the rate of occult microscopic adnexal involvement in PR low-expression group was 6.375 times of that of the gross adnexal involvement(P=0.005,95%CI:1.768-22.976),and the rate of occult microscopic adnexal involvement in the PR high-expression group was 3.719 times of that of gross adnexal involvement(P=0.048,95%CI:1.009-13.702). Conclusion PR expression level is remarkably lower in EEA patients with gross adnexal involvement than those with occult adenxal involvement.

Objective To study the expression and significance of B-cell activating factor(BAFF) and a proliferation-inducing ligand(APRIL) in patients with idiopathic thrombocytopenic purpur(ITP). Methods The serum levels of BAFF and APRIL in 27 cases with ITP were tested by ELISA.Results ①The serum levels of BAFF in ITP were higher than those of control group (3.92?1.88?g/ml vs 2.90?0.52?g/ml,P

0.05),but expression of VEGF,GLUT1 and MDR1 were all enhanced and overall proliferation was promoted,apoptosis inhibited [(11.46?0.28)% vs (29.27?0.18)%,(15.77? 0.49)% vs (31.13?0.08)%],and transmembrane behavior enhanced [(37?12)% vs (26?7)%, (40?9)% vs (28?5)%],and the variations were significant (P

To retrospectively analyze the clinical data of a child with congenital broncho-bile duct fistula(CBBF) in Guiyang Children′s Hospital in June 2019.A female, aged 7 years and 6 months old, patient presented cough with a large amount of yellow green mucus.The main clinical manifestation was recurrent pulmonary infection after birth.After the fistula was found by electronic bronchoscope, doctors cooperated with imaging department, anesthe-siology department and pediatric surgery department.After treatment, the child recovered and discharged.There are few reports on CBBF.This study suggested that, in view of the refractory pneumonia with recurrent pulmonary infection and yellow green sputum after birth, and that the effect of anti-infection treatment was poor, clinicians should pay attention to the CBBF, take bronchoscopy as soon as possible, and make early diagnosis by combining with imaging technology, thus formulating a reasonable diagnosis and treatment plan under multidisciplinary cooperation, so as to improve the diagnosis and treatment of this rare disease clinical diagnosis and treatment level, and reduce missed diagnosis and misdiagnosis as well.
