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.

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.

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.
5.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.

Objective To explore the nursing effect evaluation of vacuum sealing drainage based latissimus dorsi bridge free skin flap to repair refractory wound. Methods Thirty-seven cases of patients with intractable wounds were chosen as the observe group from January 2009 to January 2012, and 26 cases accepting the traditional way of wound care with intractable wounds were selected as control group from January 2006 to December 2008. Control group adopt conventional methods wound and the observation group accepted VSD accessories line wound negative pressure closed drainage before the wound phase 2 latissimus dorsi bridge free skin flap repairment. After treatment, the dressing time, interval and dressing change, the time of hospitalization were observed, and the nursing effect were compared after skin flap to repair for 8 days and 16 days between patients of two groups. Results The dressing time and hospitalization days in observation group after treatment were significantly less than that in control group ( <0.05), the number of dressing have significantly shortened compared with control group ( <0.01), and the dressing change interval in control group had significantly difference ( <0.01) . The effect of 2 patients in control group after skin flap to repair was poorer, but the observation group did not appear significant necrosis. Compared the good rate of two groups, the observation group patients was significantly higher than control group ( <0.01) . The therapy good rate of observation group was significantly better than that of control group (<0.01) . Conclusion The negative pressure closed drainage based ascending latissimus dorsi bridge free skin flap repairment has contributed to cure the refractory wound recovery significantly.

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.
