2.Breast Cancer During Pregnancy
Chinese Journal of Bases and Clinics in General Surgery 2004;0(01):-
Objective To study the advances in research of breast cancer during pregnancy. Methods The literatures in recent years were reviewed. Results A lot of evidences suggested that the diagnosis may be delayed easily. The diagnosis was primarily made by needle aspiration cytology and biopsy. The treatment of pregnant breast cancer was not different from ordinary breast cancer, however the factor of foetus should be taken into account. Termination of pregnancy did not improve survival.Conclusion Pregnant breast cancer is mostly at later stage at the time of diagnosis and has poorer prognosis than ordinary breast cancer. The patients with breast cancer during pregnancy usually have an equivalent survival rate when compared with age and stage-matched ordinary group. Future pregnancy may be allowed after two years of treatment in patients with early breast cancer.
3.The radiological presentations of invasive pulmonary fungal infections and its clinical value in children
Chinese Pediatric Emergency Medicine 2016;23(9):595-599
With wide applications of invasive diagnostic and therapeutic techniques,as well as immu-nosuppressors clinically,the morbidity of invasive pulmonary fungal infections( IPFIs)in children were in-creasing considerably and becoming one of the important diseases threat to life. The mortality of IPFIs in chil-dren would be reduced and the prognosis would be improved significantly with early diagnosis and treatment in-time. Radiological examinations were the basal component of the clinical evidences for diagnosing IPFIs. The main presentations include pulmonary nodules,some with“halo sign”in invasive pulmonary aspergillo-sis and pulmonary candidiasis,lobular consolidations and a little pleural effusion. Although there was no spe-cific findings radiologically,they would provide the proofs and clues for diagnosis of IPFIs combining with the data of clinics and laboratory.

Chinese Journal of Cancer Biotherapy 1996;0(04):-
The inhibition of pulmonary metastasis by inhalation of aerosolized recombinant 1L-2 (rIL-2) in BCG-primed mice is reported in this paper . (TA2 x 615) Fl mice were given ip BCG twice in two-week apart.Right after the second BCG injection, MA891 cells, a murine mammary adenocarcinoma of TA2 origin, were injected into the tail vein.Treatment with aerosolized rIL -2 by inhalation was given for 1 hr, 3 times a day and lasted for 14 days. After sacrifice, bronchoalveolar lavage was performed and the lavage fluid was examined for nitric oxide content. The number of tumor nodules on the lung surface was recorded as a measure of the extent of pulmonary metastasis. The results showed that in mice so treated, pulmonary metastasis was very significantly inhibited. When rIL-2 treatment was given in BCG-unprimed mice, inhibition of pulmonary metastasis was also observed albeit to a much lesser extent. Significant inhibition of lung metastasis was associated with significant increase in nitric oxide content in the broncho-alveolar lavage fluid. Moreover, when nitric oxide synthase inhibitor, NG monomethyl-L-arginine (7mg/kg) was given ip shortly before each inhalation of rIL-2, accompanied with a significant reduction of nitric oxide in the lavage fluid, the inhibitory effect of rIL-2 in both BCG-primed and -unprimed mice was almost completely abrogated. Taken together, the results clearly indicate that pulmonary metastasis can be effectively treated by the induction of endogenous release of nitric oxide from activated alveolar macrophages.
5.Prenatal ultrasound diagnosis of persistent right umbilical vein and its complicated abnormalities
Chinese Journal of Perinatal Medicine 2012;15(7):416-419
Objective To investigate the value of prenatal ultrasound in diagnosing fetal persistent right umbilical vein (PRUV) and structural malformations.Methods From April 2007 to August 2011,38 827 pregnant women in Obstetrics and Gynecology Hospital of Fudan University accepted ultrasound examination,among which 109 fetuses were found PRUV.The relation between PRUV and other structural abnormalities was retrospectively analyzed.Results The incidence of PRUV was 0.28% (109/38 827) including 100 singletons and 9 twins.Among the 109 cases of PRUV confirmed by the prenatal ultrasound diagnosis,95 cases did not complicate with fetal structural abnormality (90 singletons,5 twins),and had normal deliveries with healthy infants.Four infants were tested for their chromosomes and got normal results.The rest 14 fetuses with PRUV suffered from fetal structural abnormality (12.8%,14/109),among which,10 fetus (71.4%,10/14) suffered from cardiovascular abnormality such as endocrinal cushion defeats,double outlet right ventricle,single atrium and single ventricle.Nine pregnant women accepted artificial terminations.Only one of the 14 fetuses had chromosome test and got normal result.Conclusions Once PRUV was diagnosed by prenatal ultrasound,it is suggested to check the fetus carefully,especially the cardiovascular system.

AIM: To explore the role of endogenous ouabain (EO) in the development of hypertension and its secretion character in 1k1c hypertensive rats(HR). METHODS: EO contents of plasma and tissues in 1k1c HR were detected by ELISA. The relationships between plasma and tissues ouabain and blood pressure were analyzed. RESULTS: EO contents of plasma, heart, kidney, adrenal gland, pituitary and hypothalamus in lklc HR were significantly higher than those of normal rats, especially in the adrenal gland and hypothalamus. EO contents of serum, kidney and hypothalamus were correlated with blood pressure. CONCLUSIONS: EO might play an important role in the development of hypertension in 1k1c hypertensive rats. Adrenal gland might be the major source of EO.

Objective To investigate the prevalence and genotype distribution of human papilloma virus (HPV) infection among patients with cervical carcinoma or precancerous lesions in Xuzhou region. Methods 688 patients with cervical lesions confirmed by colposcopic biopsy were assigned to three groups:low-grade squamous intraepithelial lesion (LSIL) (187 cases), high-grade squamous intraepithelial lesion (HSIL) (359 cases) and cervical carcinoma (142 cases). The genotypes of HPV were determined by nucleic acid hybridization technique. The prevalence and genotype distribution of HPV were further analyzed. Results The infection rates of HPV in LSIL , HSIL and ICC group were 68.98 % (129/187), 94.99 % (341/359), 95.78 % (136/142), respectively. These rates were statistically significant different (P< 0.05). With the aggravation of cervical lesions, HR-HPV infection rate was gradually increased and LR-HPV infection rate was gradually decreased. The most common HPV types were listed below in order of decreasing prevalence. LSIL:HPV16, 52, 58, 18, 31; HSIL: HPV16, 58, 33, 31, 52; cervical carcinoma: HPV16, 31, 58, 18, 33. Based on the cumulative logistic regression model, confidence intervals of the relevance between the overall HPV prevalence and occurrence of cervical lesions were calculated: HPV16 (OR= 7.215, P< 0.05), HPV31 (OR=2.768, P<0.05), HPV33 (OR=1.846, P<0.05), HPV58 (OR=1.726, P<0.05) Conclusions The prevalence of HR-HPV infections increased with the aggravation of cervical carcinoma in Xuzhou region. In order of decreasing prevalence, the most prevalent of HPV types are HPV16, 31, 33, 58. The results indicate that HPV18 have strong tumorigenicity, but is not popular in Xuzhou region. By contrast HPV52 is more common in LSIL than that in cervical carcinoma.

Objective To compare clinical-pathological features and Ki-67 expression profile between TNBC and Non-triple-negative cancer (NTNBC). Methods The expressions of ER, PR and HER2 were examined by immunohisto?chemical Envision double staining in 226 cases of breast cancer. All cases were divided into triple-negative and non-triple-negative group according to expressions of these three episodes. And Ki-67 expressions in two groups were assessed by im?munohistochemical method. The difference of Ki-67 positive index between these two groups and the difference of Ki-67 positive index between different clinical-pathological features were both analyzed by comparative analysis. Results In pa?tients with TNBC, tumor size, lymph node metastasis rate and Ki-67 index were all significantly higher than that in NTNBC. No significant difference in age and histological grade were detected between these two groups. The expression of Ki-67 was not significant correlated with age, tumor size,lymph node status and histological grade in these two groups. Conclusion Patients with triple-negative breast cancer were with larger tumor size, higher proliferation, more lymph node metastasis and poorer prognosis.
