1.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.
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.
4.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.
5.Induced Nitric Oxide From Alveolar Macrophages Inhibits Experimental Pulmonary Metastasis in Mice
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.

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] Exploretreatment of simultaneous upper and lower diseases focusing on spleen and stomachin specific therapy of malignant tumors. [Methods]Through hackling origin of history,analyse clinical manifestations of cancer patients in viscera,limbs,guan orifices and so on.Combined with typical case,we explore concrete treatment method of treatment focusing on spleen and stomachand diet taboo and suitable. [Results]Patients with malignant tumor mostly perform simultaneous upper and lower diseasesin end-stage of disease or accepting modern medical treament frequently. According to therapeutic thoughts of paying attention to the spleen and stomach of past dynasty medical practitioners and strategic treatment methods oftreatment focusing on spleen and stomachof YE Tianshi,we proposed it should supplement the middle at first in therapy of cancer.Eliminating pathogenic factors and regulating should not damage the spleen and stomach.And we advocate using insect drug timely and appropriately to attack pathogenic qi.[Conclusions]TCM pays attention to regulating the function of the spleen and stomach in the whole treatment of cancer.

Objective To explore the intervention effects of trichostatin A ( TSA ) on specialization of rat bone marrow mesenchymal stem cells ( MSCs ) .Methods The rat MSCs were isolated, cultured and purified by the whole bone marrow adherent method in vitro, with morphological observation.The third generation of MSCs were selected, directional induced to osteoblasts, and divided into the TSA low dose group (0.1μmol/L), middle dose group (1μmol/L) , the high dose group (10μmol/L) according to different drug concentrations, seting up blank control group at the same time.MSCs proliferation and cell growth curve of each group were drawn by MMT, the activity of alkaliphosphatase ( ALP) was detected, and the levels of corebinding factor α1 (Cbfα1), basic fibroblast growth factor (bFGF) and insulin-like growth factors-1 (IGF-1) mRNA were detected by RT-PCR. Results The trend of MSCs growth curves in each groups were similar, compared with control group, the growth curve of TSA low dose group had no significant change, the TSA middle dose and high dose significantly promoted the proliferation of MSCs (P<0.05).Compared with control group, ALP activity of TSA low-, middle-and high-dose group were significantly higher at 4th,5th,6th(P<0.05).The expression levels of Cbfα1, bFGF and IGF-1mRNA were significantly higher than those of control group, respectively (P<0.05).Conclusion TSA can significantly promote the rat bone marrow mesenchymal stem cells to differentiate into osteoblast, which is possibly associated with up-regulation of Cbfα1, bFGF and IGF-1mRNA level.
