BACKGROUND Meigs’syndrome is regarded as a benign ovarian tumor accompanied by pleural effusion and ascites,both of which resolve after removal of the tumor.Patients often seek treatment in the Department of Respiratory and Critical Care Medicine or other internal medicine departments due to symptoms caused by ascites or hydrothorax.Here,we report a rare case of Meigs'syndrome caused by granulosa cell tumor accompanied with intrathoracic lesions.CASE SUMMARY A 52-year-old women was admitted to the Department of Respiratory and Critical Care Medicine due to coughing and expectoration accompanied with shortness of breath.Chest X-ray and chest computed tomography showed a modest volume of pleural fluid with pleural thickening in the right lung.The carbohydrate antigen 125(CA125)concentration was 150.8 U/mL(normal,0-35 U/mL)and no tumor cells were observed in pleural fluid.Nodules and a neoplasm with a fish meat-like appearance in the parietal pleura and nodules with a‘string of beads’-like appearance in the diaphragm were found by thoracoscopic examination.Furthermore,pelvic magnetic resonance revealed a pelvic mass measuring about 11.6 cm×10.0 cm×12.4 cm with heterogeneous signal intensity and multiple hypointense separations.Total abdominal hysterectomy,bilateral adnexectomy,and separation of pelvic adhesion were performed under general anesthesia.The pathology results showed granulosa cell tumor.At the 2-mo follow-up after the surgery,the hydrothorax subsided,and the CA125 level returned to normal.CONCLUSION For postmenopausal women with unexplained hydrothorax and elevated CA125,in addition to being suspected of having gynecological malignancy,Meigs’syndrome should be considered. 展开更多

Background To determine whether ex utero intrapartum treatment (EXIT) is an appropriate approach for managing fetuses antenatally diagnosed with giant congenital omphaloceles. Methods We retrospectively reviewed patients with omphaloceles who underwent either an EXIT procedure or a traditional repair surgery. Basic and clinical parameters including gender, gestational age, birth weight, maternal blood loss, operative times and operative complications were analyzed. During the 6–12-month follow-ups, postoperative complications including bowel obstruction, abdominal infections, postoperative abdominal distension were monitored, and survival rate was analyzed. Results A total of seven patients underwent the EXIT procedure and 11 patients underwent the traditional postnatal surgery. We found no differences in maternal age, gestational age at diagnosis, gestational age at delivery and birth weight between the two groups. In the EXIT group, the average operation time for mother was 68.3 ± 17.5 minutes and the average maternal blood loss was 233.0 ± 57.7 mL. The operation time in the EXIT group (22.0 ± 4.5 minutes) was shorter than that in the traditional group (35 ± 8.7 minutes), but the length of hospital stay in the EXIT group (20.5 ± 3.1 days) was longer than that in the traditional group (15.7 ± 2.5 days,P < 0.05). During the follow-up, one patient in the EXIT group had an intestinal obstruction, one developed abdominal compartment syndrome and one died in the traditional group. Conclusions In our experience, EXIT is a safe and effective procedure for the treatment of giant congenital omphaloceles. However, more experience is needed before this procedure can be widely recommended. 展开更多

Fuel consumption in the COREX-3000 process run in Baosteel is currently higher than the design index. Therefore, mass and heat balance equations for the COREX process were established using the basic principles in- cluded in the Rist operating diagram for blast furnace (BF) as a reference. Thermodynamic calculations were then used to modify the Rist operating diagram so that it was suitable for the COREX process. The modified Rist operating dia- gram was then applied for the evaluation of metallization rate (MR) and fuel structure to reduce the energy consump- tion in the COREX process. The modified Rist operating diagram for the shaft furnace (SF) provided a nearly ideal value for the restriction point W when the metallization rate was increased, while the point P on the operating line for the melter gasifier (MG) moved upward due to reduction in the heat required in hearth. The feasibility of reduc- ing the energy consumption during the COREX process by changing the fuel structure was also demonstrated. 展开更多
