Objective To explore the related high risk factors of hyponatremia after transsphenoidal approach for pituitary adenomectomy and to direct postoperative nursing. Methods The clinical data of seventy-seven patients suffering from pituitary adenomas with the way of treatment by transsphenoidal pituitary adenomectomy from June 2014 to May 2015 were summarized retrospectively. According to the value of postoperative serum natremia, the data were divided into hyponatremia group and non-hyponatremia group. The different data between the 2 groups were compared and the high risk factors related to hyponatremia were analyzed. Results Univariate analysis showed that gender(P=0.254) and high blood pressure(P=0.742) were unrelated to postoperative hyponatremia and there was significant difference between two groups in age (P=0.038), max- diameter of tumors(P=0.004), preoperative pituitary dysfunction (P=0.013), visual deficit (P=0.000), operative procedure duration (P=0.008) and diabetes mellitus rate (P=0.023). While Logistic regression analysis showed that preoperative visual deficit (OR=0.152,P=0.004,95%CI 0.043-0.542) and preoperative pituitary dysfunction (OR=0.069, P=0.046,95%CI 0.005-0.950) were independent factors for postoperative hyponatremia. Conclusions Hyponatremia is a common complication after transsphenoidal pituitary adenomectomy. The optimal treatment can benefit the early recovery and more careful nursing should be focused on these patients who are in high risk of postoperative hyponatremia.

BACKGROUND:The repair effects of bone marrow mesenchymal stem celltransplantation on brain injury were not ideal. Combined therapy with medicine and biological engineering materials is needed. OBJECTIVE:To investigate the effects of bone marrow mesenchymal stem celltransplantation and fingolimod immunosuppressants on memory function recovery in rats with brain injury. METHODS:A total of 60 healthy Sprague-Dawley rats were subjected to hydraulic shock with peak value of 253.312 5-303.975 kPa with a hydraulic head injury instrument so as to induce a model of severe hydraulic head injury. They were randomly divided into brain injury group, bone marrow mesenchymal stem celltransplantation group and fingolimod+bone marrow mesenchymal stem celltransplantation group. The Morris water maze test was tested at 21-28 days after PKH-26-labeled bone marrow mesenchymal stem celltransplantation. The PKH-26 immunofluorescence and hematoxylin-eosin staining were conducted in brain tissues at 4 weeks after brain injury. RESULTS AND CONCLUSION:At 4 weeks after transplantation, the average escape latency was gradual y decreased in each group. The average escape latency was shorter in the fingolimod+bone marrow mesenchymal stem celltransplantation group than in the bone marrow mesenchymal stem celltransplantation group (P<0.05), and significantly shorter than in the brain injury group (P<0.01). The number of times of crossing the platform and the percentage of swimming distance to total distance were higher in the fingolimod+bone marrow mesenchymal stem celltransplantation group than in the brain injury group and bone marrow mesenchymal stem celltransplantation group (P<0.05). The number of PKH-26-positive cells was significantly higher in the fingolimod+bone marrow mesenchymal stem celltransplantation group than in the brain injury group and bone marrow mesenchymal stem celltransplantation group (P<0.05). Results confirmed that bone marrow mesenchymal stem celltransplantation could apparently improve memory function of rats with severe brain injury. The combined application of fingolimod immunosuppressants has synergistic effects.

Extracellular vesicles (EV) miRNAs are a class of small non-coding RNAs that are encapsulated in membrane-containing vesicles from a variety of cells, and which can mediate intercellular communication and transfer of functional molecules. EV miRNAs in circulation can be served as novel molecular markers for cancer diagnosis, monitoring and prognosis, and also the most promising liquid biomarkers for clinical translation and utility currently, while optimal research strategy is crucial for identifying valuable EV miRNAs in clinical study. Moreover, EV miRNAs have recently also been implicated in cancer progression as direct regulators of metabolic reprogramming, mesenchymal-to-epithelial transition, angiogenesis, anti-cancer immune response and drug resistance in the tumor microenvironment. Study on some key EV miRNAs involving in those processes may highlight their potential utility as liquid biopsies in early diagnosis, companion diagnosis, metastasis, therapeutic control, prognosis analysis as their therapeutic potential for patients with cancer.

Objective To observe the injuries of sodium citrate plasma(scP) on the growth and function of HepG2 cells.Methods The HepG2 cells were cultured.The viability,cell cycle and apoptosis,the leakage of LDH,total protein,glutathione and the changes on morphology of hepatocytes exposured to scP were investigated.Results The viability of HepG2 cells was inhibited when the cells were cultured in scP for 24h(F=37.108,P=0.001).After 48h,nearly all cells died except cells in 10% scP group.After the cells were exposed to scP for 24h,the percentage of S phase of the cell cycle and the rate of apoptosis were significantly increased compared to those of the control.The leakages of LDH were increased in the HepG2 following exposure to scP for 5h(P

Objective To study the practicability and preliminary effect of intraluminal brachytherapy in treatment of malignant obstructive jaundice.Methods Intraluminal brachytherapy was performed in 4 patients who had been treated with biliary stent implantation. Results No complications related to intraluminal brachytherapy had happened.One patient was followed up by means of CT,showing reduction in tumor size. Conclusion Intraluminal brachytherapy is a safe and effective method in treating malignant tumor causing obstructive jaundice.

Objective:This study aimed to analyze the prognostic factor of bilateral hydronephrosis caused by advanced cervical cancer and evaluate its value of treatment. Methods:A total of 40 patients with bilateral ureteral obstruction secondary to cervical cancer were diagnosed through computerized tomography, radioactive nephrogram, and blood tests for renal function. The placement of retrograde internal double-J ureteral stents was performed under a cystoscope in 13 patients. The placement of antegrade internal double-J ureteral stents via percutaneous nephrostomy was performed in 25 patients. Two cases had external ureteral stents via percutaneous nephrostomy. Twenty-nine patients underwent radiotherapy after normalization of their blood urine nitrogen and creatinine levels. The prognostic value of the treatment and renal function before placement of ureteral stents and radiotherapy after placement of ureteral stents were analyzed. Results:The normalization rate of renal function after ureteral stenting was 91.3%(21/23). The median survival time was longer in patients with untreated cervical cancer than that in patients with recurrent cervical cancer (χ2=9.379, P=0.009). After ureteral stenting, the median survival time was longer in patients who underwent radiation therapy than that in patients untreated with radiation (χ2=17.329, P=0.000). The median survival time was not significantly influenced by renal function before placement of ureteral stents (χ2=1.37, P=0.242). Conclusion:The patient with bilateral ureteral obstruction from untreated cervical cancer or from recurrent pelvic disease after surgical therapy should be considered for ureteral stenting followed by appropriate radiation.

Method: Thirty patients were divided into E (etomidate,n=15)and M(midazolam,n=15)groups,receiving a infusion of etomidate or midazolam until their eyelash reflex was lost. After pipeuronium(0.15mg/kg) and fentanyl were administered according to the mean blood pressure,the intubetion was achieved. Hemodynsmic and oxygen data were measured before induction, during induction and 1 min after intubation. Result: Induction caused a significant fall in HR,MAP,SVRI,PVRI and VO_2I in both groups (P

Objective To study the growth suppression effect of 131 I labeled anti KDR monoclonal antibody on the tumor tissue of human bladder cancer subcutaneously implanted in SCID mice. Methods The SCID murine model was established by subcutaneous implantation of human bladder cancer in mice. The 131 I labeled anti KDR monoclonal antibody (3G9) was injected into the caudal vein of mice (experimental group). The anti KDR monoclonal antibodies and saline were injected into the caudal vein of the mice (control group and blank group, respectively). The growth suppression effect of 131 I labeled anti KDR monoclonal antibody on the tumor tissue of SCID mice bearing human bladder cancer was observed. Results Tumor tissue necrosis was found in the mice of the experimental group and the control group at 3 weeks after the injection. Compared with that in the blank group, the growth suppression ratio in the experimental group and the control group were 96.8% and 87.7%, respectively. Conclusion 131 I labeled anti KDR monoclonal antibody may be of potential clinical significance in the anti angiogenesis therapy for human cancer.
