The paper introduced the present full-time practice of medical social workers in China, with in-depth analysis of the roadblocks encountered.The problems include but are not limited to multiple stakeholders without a healthy resources relationship network, lack of powerful government support in policy and resource orientation, absence of drivers for hospitals to deliver social service, immature social organizations, and poor capacity to link resources.Based on such, the authors explored the establishment of a development model for full-time medical social workers on a multiple cooperation platform, in such perspectives as the government, social worker organizations, hospitals, and third-party performance appraisal.

After being restored, 69 cases of the two-implant-supported crowns were followed up for 5 years. Except 1 case failed after restored 5 years due to peri-implantitis, and there were no complications which can not be controlled in the other cases. The success rate of implant restoration in 5 years is 98.6%. The two-implant-supported single crown for molar is an effective method to restore the long gap of a single molar-loss.

Objective: To investigate the effect of colloidal solution infusion on cerebral blood flow in patients with cerebral vasospasm after aneurysmal subarachnoid hemorrhage. Methods: Thirty patients diagnosed as aneurysmal subarachnoid hemorrhage with digital subtraction angiography (DSA) were divided into a vasospasm group (n = 12) and a control group (n = 18) according to whether they had cerebral vasospasm or not. After evaluating the regional cerebral blood flow (rCBF) of the bilateral anterior cerebral artery, middle cerebral artery and posterior cerebral artery with Xe-CT, the colloidal solution (succinylated gelatin, 4 mL/kg) was injected intravenously in the patients of the vasospasm group within 30 minutes. Xe-CT was performed again, and the changes of rCBF before and after the colloidal solution expansion were compared. The changes of blood pressure, heart rate, and central venous pressure before and after infusion were documented. Results: Circled digit oneThe rCBF of bilateral anterior cerebral artery, middle cerebral artery and posterior cerebral artery was more than 30 mL·100 g-1·min -1 in the control group. The rCBF was lower than 30 mL·100 g-1·min-1at least in 1 blood supplied region in the vasospasm group (72 blood supply regions altogether) , in which CBF were lower than 25 mL·100 g-1·min-1 in 7 blood supplied regions. Circled digit twoBefore and after the expansion, there were no significant differences among the systolic and diastolic blood pressure, mean arterial pressure, and central venous pressure in the vasospasm group (P >0.05). Circled digit threeOf the 65 vessels with rCBF >25 mL·100 g-1·min-1 there were no significant differences in rCBF before and after the expansion (P = 0.272) ; of the 7 vessels with rCBF ≤ 25 mL·100 g-1·min-1, the rCBF increased from 20 ± 3 mL·100 g-1·min-1to 34 ± 6 mL·100 g-1·min-1. There were significant differences (P <0.01). Circled digit oneOne year follow-up after the procedure, there was no significant difference in GOS score between the 2 groups. Conclusion: Colloidal solution expansion may increase the rCBF of the ischemic regions in patients with cerebral vasospasm and help to improve the prognosis of the patients.

Objective To construct a reliable continent tube, which is easy to catheterize and is surgically simple. Methods 10 patients with bladder cancer underwent a procedure in which ileal segment was tapered as an efferent tube,a part of which was placed between the back surface of the rectus muscle and wall of the ileal pouch. Internal orifice of the tapered ileum was anastomosed to the ileal pouch and external orifice of the tapered ileum was anastomosed to umbilicus. Urodynamic and radiological studies were carried out postoperatively on 9 patients. Results The stoma could be easily catheterized with a 16 F catheter in all the patients. One patient died of heart disease 55 days postoperatively. In the other 9 patients, 8 were completely continent day and night. The urodynamic study of the efferent tubes showed a maximum close pressure with a full pouch was significantly higher than those with an empty pouch (t=-7.14,P=0.000098 ). Retrograde radiogram of the efferent tubes showed perfect canalization without stenosis. Conclusion This study suggested that the continent mechanism of tapered ileum can be greatly enhanced by fixing it between the abdominal and the pouch wall,allowing also easy catheterization and surgical simplicity.
