To prepare bio-degradable albumin microspheres containing carboplatin. METHODS: Bovin serum albumin microspheres containing carboplatin were prepared by using emulsion-direct heat cross linking techniques. RESULTS: The microsphere was yellow, powdery, with a mean diameter of 58.2 μm. The microphere loaded (11.26±0.48)% carboplatin. The trapping efficiency was (84.5±3.6)%. The pattern of drug releasing from the microspheres in vitro fitted to zero order release plot, with an initial burst in the first 2 hours. The releasing rate can be expressed by the follow equation: Q=21.90+8.50 t (d), r=0.995 8. t50=3 d. Stored at 4 ℃ and 37 ℃ respectively for 3 months, the microspheres did not alter much in shape, size and drug content. CONCLUSIONS: This method is simple, reproducible, having high drug trapping efficiency. The microsphere obtained is stable and release drug at a consistant rate in vitro, leading to a prosperity in clinical use.

Objective To explore the expression of estrogen sulfotransferase(EST) and steroid sulfatase (STS) in formalin-fixed paraffin-embedded endometrioid adenocarcinoma samples. Methods The RNA of EST and STS in 30 formalin-fixed paraffin-embedded endometrium samples were extracted using Roche products. Results The RNA expression of EST and STS were 0.25±0.03 and 0.08±0.02 respectively and the STS/EST was 0.11±0.08 in normal endometrium. While in endometrioid adenocarcinoma the RNA expression of EST and STS were 0.06±0.02 and 0.24±0.92 respectively and the STS/EST was 4.40±0.64. There were significant differences between these two groups. Conclusions (1) Formalin-fixed paraffin-embedded tissues could be used to study the endometrioid adenocarcinoma. (2) EST is decreased, STS and STS/EST are increased in human endometrioid adenocarcinoma. STS/EST may be related with the prognosis of the endometrioid adenocarcinoma.

Objective To study the incidence of malignant change, diagnosis and management of mature cystic teratomas in postmenopausal women. Methods Twenty cases of mature cystic teratoma in postmenopausal women admitted to our hospital between January 1977 and January 1997 was retrospectively reviewed and evaluated. Results The number of postmenopausal patients with mature cystic teratoma (20) accounted for 7.6% of the total number of patients with benign ovarian teratomas (263). There were 3 cases of malignant change, which were squamous carcinoma, carcinosarcoma, and digestive gland epithelial carcinoma. The incidence of malignant change was 15%. Conclusion In postmenopausal women, mature ovarian cystic teratoma should be treated as lowly malignant and should be paid much attention.

Methods: Male SPF SD rats were selected as experimental animals and randomly divided into four groups. Sham group received sham operation, I/R group were made into myocardial ischemia reperfusion injury models, FDP group were made into myocardial ischemia reperfusion injury models and then were given FDP intervention, and FDP+AG490 group were made into myocardial ischemia reperfusion injury models and then were given FDP and JAK2 inhibitor AG490 intervention. Results: CK, CK-MB, cTnI and LDH contents in serum as well as Bax and Caspase-3 protein expression in myocardial tissue of I/R group were significantly higher than those of Sham group whereas Bcl-2, p-JAK2 and p-STAT3 protein expression in myocardial tissues were significantly lower than those of Sham group; CK, CK-MB, cTnI and LDH contents in serum as well as Bax and Caspase-3 protein expression in myocardial tissue of FDP group were significantly lower than those of I/R group whereas Bcl-2, p-JAK2 and p-STAT3 protein expression in myocardial tissue were significantly higher than those of I/R group; CK, CK-MB, cTnI and LDH contents in serum as well as Bax and Caspase-3 protein expression in myocardial tissue of FDP+AG490 group were significantly higher than those of FDP group whereas Bcl-2 protein expression in myocardial tissue was significantly lower than that of FDP group. Conclusion: FDP could reduce the myocardial ischemia reperfusion injury in rats by activating the JAK2/STAT3 pathway.

This study was aimed to observe the effect of Bai-Zhu Fu-Ling (BZFL) Decoction in different proportion-ing on VIP and VIPR1 in Crohn's disease (CD) rats with spleen deficiency syndrome, in order to further explore the immunologic mechanism of BZFL Decoction on CD. The CD rat model with spleen deficiency syndrome was estab-lished using exhaustion and hunger. The model rats were treated by BZFL Decoction with different proportioning, and immunohistochemistry (IHC) was used to detect the expression of VIP and its receptor in colon tissues. The results showed that comparing to the blank control group, the level of VIP and its receptor of the model group significantly increased (P< 0.05). Comparing to the model group, the level of VIP and its receptor in BZFL Decoction B5 group (Rhizoma A tractylodis Macrocephalae:Poria = 12:15), B6 group (Rhizoma A tractylodis Macrocephalae:Poria = 15:12) and B7 group (Rhizoma A tractylodis Macrocephalae:Poria = 18:9) was significantly decreased (P< 0.05). It was con-cluded that the effect of BZFL Decoction of B5 group, B6 group and B7 group was better than other groups in VIP and its receptor which can regulate the VIP and its receptor, inhibit the releasing of inflammatory factors and reduce intestinal inflammation injury.
