Objective　To observe the effects of epithelial growth factor (EGF) and basic fibroblast growth factor (bFGF) on wound healing of the penetration keratoplasty (PKP) with autograft in rabbits. Methods　After the establishment of penetrating keratic autograft model on 24 rabbits, they were equally divided into EGF-, bFGF-, EGF+bFGF-treated and control groups. The wound healing of all the animals were observed with healing intensity, liquid scintillation counter, AgNORs staining, VG staining and transmission electron microscopy. Results　①EGF, bFGF, and EGF+bFGF increased the limiting pressure of the wounds and the 3H-TdR incorporation. ②The fibroblast cells and its secreting proliferative collagen in both the bFGF group and EGF+bFGF group were more well-arranged. Conclusion　①EGF, bFGF, EGF+bFGF can obviously elevate the intensity of wound healing after PKP and enhance the synthesis of DNA. ②The effect of this agent combination is just as the same as bFGF applied alone 14 d after the operation. ③bFGF can improve the quality of wound healing after PKP.

0.97).The method of Real-time PCR and molecular beacon detection for bifodobacteria has many advantages,such as being sensitive,specific,simple and fast,and this method can be used in situ detection of bifidobacteria quantitatively.

Objective To determine multiple inorganic anions in drinking water with ion chromatography,such as F~-,Cl~-, NO_2~-,Br~-,HPO_4~(2-),NO_3~-,SO_4~(2-).Methods The ion chromatography was used.The optimized conditions were explored.Results Under the selected flow rate(1.5 ml/min),the optimal concentration of eluent NaHCO_3 and Na_2CO_3 was 2.0?10~(-3)and 3.0?10~(-3) mmol/L,under the concentration of eluent,the optimum pump flow rate was 1.5 ml/min,the recovery rate was 94.69%-102.20%. Conclusion This method is applicable to the determination of multiple inorganic anions in drinking water.

Objective　To observe the effect of epidemic growth factor (EGF) combining with basic fibroblast growth factor (bFGF) on wound healing of the penetrative keratic autoplasy in rabbits. 　 Methods　All 18 rabbits (36 eyes) were randomly divided into 9 groups and undergone penetrative keratic autoplasy, eyedrop.Diameters of the trephines were all 6 mm. Liquid scintillation counter was used to measure the incorporation rate of 3H-TdR. Pressure-detector was used to survey the intensity of keratic wound healing. AgNORs staining was used to count the fibroblast cells at keratic wound. VG staining, AgNORs staining and transmission electron microscopy were used to observe the morphological changes of keratic wound.　Results　(1) Both the wound intensity and the number of fibroblast cells of combination groups were higher than the 2 control groups in 8 days. (2) From the 14 th day to 21 st day, the wound intensity, the number of fibroblast cells and the incorporation rate of 3H-TdR in wound healing had no obvious difference from the positive control groups. 　Conclusions　 At the primary time, EGF combining with bFGF topic is more efficient to accelerate the wound healing of PKP. But the effect of this combination topic is just the same as bFGF topic alone 14 days later.

Objective To investigate surgical treatment for tumor involved inferior vena cava at the upper segment of kidney.Methods The clinical data of 35 patients with tumor involved inferior vena cava at the upper segment of kidney who were admitted to Changhai Hospital affiliated to the Second Military Medical University from January 2007 to May 2015 were retrospectively analyzed.All the patients received preoperative imaging examinations to insure the site and range of inferior vena cava involvement at the upper segment of kidney.Renal cell carcinomas with inferior vena cava involvement were found in 19 cases,leiomyosarcomas of inferior vena cava in 5 cases,leiomyomatosis involving inferior vena cava in 3 cases,adrenocortical carcinoma involving inferior vena cava in 3 cases,liver cancer involving inferior vena cava in 2 cases,right adrenal pheochromocytomas in 2 cases,retroperitoneal fibrosarcoma involving inferior vena cava in 1 case.According to tumor involvement types,the different surgical approaches,planes and method of inferior vena cava exclusion,reconstruction method and prevention of tumor embolus detachment were selected.Patients were followed up by outpatient examination and telephone interview till May 2015.Results Among 19 patients with renal cell carcinomas with inferior vena cava involvement,10 patients were placed inferior vena cava filters through internal jugular vein before surgery,10 patients underwent total hepatic vascular exclusion and 9 patients underwent intrahepatic inferior vena cava exclusion.All the 19 patients received tumor resection and inferior vena cava embolectomy.Of the 5 patients with leiomyosar-comas of inferior vena cava,3 patients underwent total hepatic vascular exclusion and 2 patients underwent intrahepatic inferior vena cava exclusion.The diseased segments of 5 patients were resected,including 4 patients of artificial vascular graft and 1 patient complicated with resection of right kidney receiving simple ligation of inferior vena cava and left renal vein at proximal and distal tumors.Of the 3 patients with leiomyomatosis involving inferior vena cava,2 patients received total hepatic vascular exclusion and 1 was treated surgically under cardiopulmonary bypass.All the 3 patients underwent inferior vena cava embolectomy and hysterectomy.Three patients with adrenocortical carcinoma involving inferior vena cava and 2 patients with liver cancer involving inferior vena cava underwent total hepatic vascular exclusion.Among the 5 patients,4 had direct suture after tumor removal combined with partial inferior vena cava resection,and 1 had patch repair after partial inferior vena cava resection.Two patients with right adrenal pheochromocytomas were exposed proximal and distal lifting devices of inferior vena cava without clamp,and the tumors were peeled off completely.Intraoperative death happened in the patient with retroperitoneal fibrosarcoma involving inferior vena cava who was prepared to undergo intrahepatic inferior vena cava exclusion but encountered intraoperative pulmonary embolism due to tumor thrombus shedding.Thirty-four patients of 35 patients underwent operation successfully without serious perioperative complications and a patient died in the perioperative period.The mean operation time,volume of intraoperative blood loss and duration of postoperative hospital stay were 2.8 hours (range,1.5-5.0 hours),2 000 mL (range,400-5 000 mL) and 9.2 days (range,6.0-16.0 days).Thirty-four patients were followed up for a median time of 12 months (range,1-60 months).During the follow-up period,a patient with leiomyosarcomas of inferior vena cava and 2 patients with adrenocortical carcinoma involving inferior vena cava died of tumor recurrence,a patient with liver cancer had tumor recurrence,other patients were tumor-free survival.Conclusions Inferior vena cava at the upper segment of kidney is not contraindication for tumor resection.The appropriate way to expose,clamp and reconstruct are selected to safely remove the tumor based on extension and method of tumor involving inferior vena cava.

Type 1 diabetes mellitus(T1DM) is a chronic autoimmune disease.Prospective studies carried out in T1 DM pre-diabetic relatives have shown that the process of β-cell degeneration can take place before the disease manifests itself clinically.Scholars have made several breakthroughs in immune therapy for T1 DM.This paper will make a review of the latest progress in the antigen-specific,antibody-based,cell-based,and other immunotherapies of T1DM.
