A 70-year-old man was hospitalized for gastric cancer that was detected during screening by esophagogastroduodenoscopy (EGD). Initial laboratory data showed the increased serum level of AFP and EGD revealed a 5-cm ulcerofungating mass in the greater curvature of the gastric antrum. The patient underwent radical subtotal gastrectomywith D2 lymph node dissection and Billroth gastrojejunostomy. Histopathological evaluation confirmed double primary gastric cancer: gastric choriocarcinoma admixed with an AFP-producing adenocarcinoma and separated adenocarcinoma. At 2 wk postoperatively, his human chorionic gonadotropin and AFP levels had reduced and six cycles of adjuvant chemotherapy were initiated. No recurrence or distant metastasis was observed at 4 years postoperatively.展开更多

Under field conditions, acceptable results may be achieved with ultrasonography from days 25 to 30 post-AI. The reliability of the test greatly depends on the frequency of the transducer used, the skill of the examiner, the criterion used for a positive PD （pregnancy diagnosis） and the position of the uterus in the pelvic inlet. Pregnancy protein assays （PAG, PSPB） may provide an alternative method to ultrasonography for determining EP or LEM/EFM （late embryonic/early foetal mortality） in the cow. Although early pregnancy factor is the earliest specific indicator for fertilization, its detection is entirely dependend on the use of the RIT （rosette inhibition test）, therefore its use in the field needs further inventions. Preventive pharmaceutical treatments with hCG （human chorionic gonadotropin）, GnRH （gonadotropin realising hormone）, PRID （progesterone-releasing intravaginal device） or CIDR （controlled internal drug release） inserts at different time periods at or post-AI may have some benefit in decreasing PL （pregnancy loss）, however further examinations are warranted to determine how and when these treatments may influence PL in the field.展开更多
