Management of adrenocortical tumor are developing vigorously,from diagnostic treatment to precisely therapy with endocrine lab test and radiology examination improving.The prevalence rate of incidental adrenal mass is 7％.Update researches show that surgical treatment is beneficial in subclinical hypercorisolism patients combined with adrenal incidentaloma.Histopathology improves the evaluation of prognosis in primary aldosteronism patients.For adrenocortical cancer patients,mitotane with combination of etoposide,doxorubicin and cisplatin after surgical treatment was recommended,while adjuvant radiotherapy needs more study to conform the efficacy.

BACKGROUND: The ulcer wound is hard to heal in diabetic patients,and it is believed to be caused by the microcirculatory disorder of wound and decreased contents of endogenous growth factors in patients with diabetes mellitus.OBJECTIVE: To observe the biological effects of adeno-associated virus (AAV) mediated transforming growth factor beta1 (AAV-TGFβ1) and vascular endothelial growth factor (AAV-VEGF) in promoting the dermal ulcer healing of diabetic rabbits.DESIGN: A randomized controlled animal experiment.SETTINGS: Medical College, Qingdao University; Affiliated Hospital of Medical College, Qingdao University.MATERIALS: The experiments were carried out in the gynecological laboratory, Affiliated Hospital of Medical College, Qingdao University from July 2004 to January 2006. Twenty-four healthy adult New Zealand rabbits were randomly divided into co-transfection group (n=12) and control group (n=12).METHODS: ① The dermal ulcer models of diabetic rabbits was established by injecting alloxan (130 mg/kg) via ear vein, and the ulcer wound was made by operation. ② In the co-transfection group, the wound was locally infiltrated, and injected with AAV-TGFβ1 virus and AAV-VEGF virus (the concentration was 9×106 virus granules/mL respectively). The rabbits in the control group were treated with injection of saline.MAIN OUTCOME MEASURES: ① The levels of TGFβ1 and VEGF gene transcription in the healing tissue were detected with polymerase chain reaction (PCR) at 1 month postoperatively. ② The capillary density in the wound margin was counted with microcirculation microscope at 3 weeks postoperatively. ③ The collagen Ⅰ and Ⅲ were isolated and detected with Western blotting by protein gel electrophoresis and semi-dry electrophoretic transfer. ④ The content of collagen in the ulcer healing issue was detected at 1 day, 1, 2 and 3 weeks, 1, 2, 3, 4, 5 and 6 months postoperatively. ⑤ The thickness, color and quality of the wound healing were observed postoperatively.RESULTS: All the 24 rabbits were involved in the analysis of results. ① The expressions of TGFβ1 and VEGF gene transcription in the co-transfection group were increased as compared with those in the control group. ② The capillary density at the wound margin in the co-translection group was higher than that in the control group [(19.18±3.56), (6.43±1.52)/mm2,t=3.21, P ＜ 0.05]. ③ The content of collagen Ⅰ in the ulcer healing tissue in the co-transfection group was obviously increased, and the proportion of collagen Ⅰ in the constituent ratio of collagen Ⅱ and Ⅲ was increased.④ The contents of collagen in the ulcer healing tissue at 1 day after transfection were close without significant difference between the two groups (t=1.55, P ＞ 0.05). After that, the contents of collagen in the cotransfection group were all significantly higher than those in the control group (P ＜ 0.05). ⑤ The ulcer healing in the control group was obviously lagged with bad quality.CONCLUSION: The combination of AAV-TGFβ1 and AAV-VEGF can efficiently transfect the dermal ulcer wound in diabetic rabbits, obviously increase the capillary density in ulcer tissue, markedly improve the proportion of collagen I in the constituent ratio of collagen Ⅰ and Ⅲ in healing tissue, and obviously ameliorate the condition of ulcer healing.

Objective To observe the effectiveness of lactobacillus acidophilus combined with electroacupuncture on gastrointestinal function in patients with traumatic brain injury. Methods A total of 167 patients with traumatic brain injury treated in our hospital from June 2013 to December 2016 were randomly divided into combining treatment group (n=84) and lactobacillus acidophilus group (n=83). The lactobacillus acidophilus group was given routine treatment and lactobacillus acidophilus. The combining group was given the routine treatment, electroacupuncture treatment and lactobacillus acidophilus. Data of gastronintestinal function, infection, pH of gastric juice, serum two amine oxidase (DAO) and D-lacticacid level were compared between two groups. Results Compared with lactobacillus acidophilus group, the incidence rates of reflux (χ2=7.948), vomit (χ2=7.514), diarrhea (χ2=4.521), abdominal distension (χ2=5.968), pulmonary infection (χ2=4.521) and enterogenic infection (χ2=4.531) were significantly decreased in the combining treatment group (P<0.05). After 20-day treatment, pH value of gastric juice (t=8.125) was significantly increased, the serum DAO value (t=6.383) and D-lacticacid level (t=6.745) were decreased, in combining treatment group than those of lactobacillus acidophilus group (P<0.05). Conclusion Lactobacillus acidophilus combined with electroacupuncture can improve the gastrointestinal function, stimulate gastric acid secretion and decrease serum levels of DAO and D-lacticacid.

With the emergence of new technologies such as brain imaging, bio-sensing, human-computer interaction, cloud computing and large data, the treatment of traumatic brain injury has entered a new era. However, it must be clearly recognized that the central nervous system (CNS) trauma remains a worldwide medical problem. Based on the existing medical knowledge, it is important for promoting CNS trauma treatment levels including nerve trauma standardized treatment, professional management team, multi modal monitoring and data analysis, actively participating in domestic and international multi-center clinical research. Medical workers should dare to explore and innovate, keep up with the pace of the times, and truly achieve the overall improvement of nerve trauma.

In recent years, the rapid development of stem cell transforming technology and regeneration pose great re?search value. With maturation of transformation induction, other cell lineages were shown to be able to transform into neu?rons. In addition, astrocytes are widely distributed in the gray and white matter of the central nervous system, whose exces?sive proliferation contribute to glial fibrillary scar formation, which is the key obstacle in recovery of neurological function. Therefore, the study of transforming astrocytes into neurons draw attention from many scientists. Astrocytes transformation not only prevent the formation of glial scar, but also generate new neurons. This article summarized relevant studies that re?port function of astrocytes and its transformation into neurons.

Objective To explore emergency treatment strategies for the patients with brain hernia combined with hemorrhagic shock after severe traumatic brain injury and their effect on prognosis.Methods A retrospective analysis was made on 54 patients (study group) with brain hernia combined with hemorrhagic shock treated with selective treatment strategies from May 2006 to May 2009. Another 48 patients with the same injuries treated with no selective treatment strategies from April 2003 to April 2006 were used as control group. The mortality within one week and the GOS six months after injury were compared in two groups. Results There was no statistical difference in aspects of sex, age, injury mechanism, GCS and blood loss in both groups (P＞0.05). Thirteen patients died in the study group within the first week, with mortality rate of 24.1%. While 16 patients died in the control group at the first week, with mortality rate of 33.3% (P＜0.05). GOS half year after injury in the study group was better than that in the control group (P＜0.05).Conclusion Early selective treatment strategy based on degree of shock may obtain better outcome for patients with brain hernia combined with hemorrhagic shock after severe brain injury.

Objective To study the feasibility of stem cell transplantation under mild hypothermia so as to provide a prerequisite for stem cell transplantation in patients with traumatic brain injuries (TBI) during mild hypothermia treatment. Methods After transfecting plasmid containing temperature-sensitive simian virus 40 large T-antigen (tsSV40LT) into temperature-sensitive umbilical cord mes-enchymal stem cells (tsUCMSCs) , the changes of cell morphology, nuclear proliferation index (PIx) and telomerase activity were detested when the tsUCMSCs were cultured at 33℃ and 37℃. After the mouse model with tTBI treated with mild hypothermia was established, tsUCMSCs were transplanted into semi-injury area to detect survival rate, proliferation and apoptosis indices and perform neurological deficit scoring. Results When cultured at 33℃, the tsUCMSCs displayed long spindle-shaped and highly refractive, with higher proliferation index and telomerase activity than those cultured at 37℃. Compared with control group (non-temperature-sensitive UCMSCs transplantation), tsUCMSCs in semi-injury area showed much higher cell survival and proliferating cell nuclear antigen expression ( P < 0.05 ) , with fewer apoptotic cells and better neurological function (P < 0.05). Conclusion The establishment of temperature-sensitive stem cell line enables stem cell transplantation during treatment of TBI with mild hypothermia, as provides us a new direction for treatment of TBI.
