Primary seminal vesicle adenocarcinoma (PSVA) is an extremely rare disease without any unified diagnostic criterion. Differential diagnosis of PSVA from prostate cancer, colon cancer, and bladder cancer is necessary but difficult because of the lack of standard management. Radical resection is considered the mainstay of primary treatment that offers satisfactory prognosis. Most cases with PSVA are diagnosed at advanced stages because its early manifestation is nonspecific and it is rarely diagnosed in clinic. In this study, we described the case of a 52 year-old PSVA patient who was treated at the Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, in July 2012. The patient underwent local excision, with tumor residuals visible under the naked eye. The patient benefits from a six-cycle paclitaxel (175 mg/m2) therapeutic regimen combined with cisplatin (60 mg/m2), as well as pelvic modulated radiotherapy with a radiation dose of 60 Gy/30 F. At present, the patient is disease-free and undergoes regu-lar follow-up.

Objective To investigate the effect and mechanism of valproic acid in preventing astrocyte proliferation around the central canal of rats following spinal cord injury.Methods Forty-five Wister rats were divided into normal control group (n =5),injury group (n =20) and treatment group (n =20) according to random number table.Animal models of acute spinal cord injury were produced at T10 using Allen' s method by dropping a 10 g weight from a 15 mm height.Rats in treatment group received intraperitoneal injection of valproic acid (300 mg · kg-1 · d-1 in two divided doses) at 30 minutes postinjury.Instead,rats in injury group were injected with an equal volume of saline in the same way.Hindlimb function was evaluated using BBB scoring system at 1,3,7,and 14 days postinjury.Astrocytes proliferation around central canal and expression of glial fibrous acid protein (GFAP) were examined.Results In normal control group,few astrocytes around spinal central canal and a low expression of GFAP were detected.In injury group,astrocytes began to increase at 24 hours postinjury; fluorescence intensity for GFAP was 24.6 ± 3.6 at 24 hours,reached a peak of 69.2 ± 6.4 at 3 days,maintained a high level of 56.7 ± 5.6 at 7 days,and reduced to 35.4 ± 4.3 at 14 days,a level that remained higher than that in normal control group (11.2 ± 1.6).Whereas in treatment group at 3 and 7 days,astrocyte proliferation around spinal central canal was lower than that in injury group; GFAP expressions (47.8 ± 5.3 and 42.2 ± 6.7) were lower than those in injury group (F =177.6,P ＜ 0.05).At 3,7,and 14 days,BBB scores in treatment group (7.80 ± 0.83,12.00 ± 1.58,and 16.60 ± 1.12 respectively) were significantly higher than those in injury group (4.60 ± 0.54,6.65 ± 0.67,and 9.40 ± 1.14 respectively) (F =1 113.6,P ＜ 0.05).Conclusion After spinal cord injury,valproic acid reduces astrocyte proliferation around central canal via inhibiting GFAP expression to promote functional recovery.

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.
