Chinese Journal of Tissue Engineering Research 2014;(28):4469-4473
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.
2.Clinical analysis of the related high risk factors of hyponatremia after transsphenoidal approach for ;pituitary adenomectomy andclinical nursing
Chinese Journal of Practical Nursing 2016;32(26):2030-2032
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.
3.Clinical value and prospect of extracellular vesicle miRNAs as novel liquid biopsy molecular biomarkers of tumor
Chinese Journal of Laboratory Medicine 2021;44(3):250-254
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.

6.Pregnancy-associated plasma protein-A and ischemic stroke
International Journal of Cerebrovascular Diseases 2010;18(5):377-380
Pregnancy-associated plasma protein-A (PAPP-A),a high-molecular-weight zinc-binding metrix metalloproteinase,is expressed abundantly in the ruptured atherosclerostic plaque. PAPP-A can be used as a novel biological marker of plaque instability and cardiovascular events in patients with acute coronary syndrome. However,the role of PAPP-A in iscbemic stroke remains unclear. This article reviews the value of VAPP-A in predicting the risks of ischemic stroke events.

9.Application of a quantitative history for vasovagal syncope
International Journal of Pediatrics 2011;38(6):541-544
Vasovagal syncope (VVS) is the most common cause of transient loss of consciousness ( TLOC ),mainly with head-up tilt test (HUTT) for diagnosis and treatment evaluation.Beacause of potential risks in the process of HUTT,it is necessary to explore an early,accurate,safe,effective,inexpensive and convenient means of diagnosis and evaluation for VVS.The means of quantitative history are now in practice of clinical trials.The means commonly used are Calgary Presyncope Form (CPF)and three questionaires about point scores in the Calgary syncope symptom studies.Due to its stable,simple and easy to apply features,CPF has some advantages on assessing the effectiveness of different treatment methods for VVS.The three questionnaires have some application potential in diagnosis for VVS.
10.Research advances of middle ear effusion due to radiotherapy of head and neck carcinoma
China Oncology 2001;11(2):178-180
The incidence of middle ear effusion due to radiotherapy of head and neck carcinoma is as high as 16—26 percent.Irradiation causes tissue reactions such as congestion,edema, mucositis and fibrosis, which is responsible for the postirradiation tubal dysfunction. The tubal function is worst 6 months after radiotherapy . The cancer disappears after radiotherapy, but the tubal dysfunction still would happen if inflammation and local radiotherapy-induced oedema exist. The tubal function improved at 5 years after radiotherapy if the irradiation dosage is below 70 Gy in patients with nasopharyngeal carcinoma. The mean radiation dosage in the ears with patulous tubes compared for tubals with normal opening has no significant difference. The incidence of otorrhea is very high 2 years after radiotherapy in patients treated by myringotomy and ventilation tube insertion. The tubal function may become normal without treatment and patulous tubes may develope 5 to 10 years after radiotherapy.
