Objective To discusses the value of combined CA125 and CT/MR/ in diagnosing the ovarian thecoma.Methods Forty cases of patients with ovarian thecoma were retrospectively analyzed.The results of CA125 and the appearance of CT and MRI were recorded,the value of CA125 changes and CT/MRI features was analysed in the diagnosis of ovarian thecoma.Results The value of CA125 elevated in 17 cases of ovarian thecoma,and showed statistical significance in the ratio((12/35 vs.5/5;x2=2.274,P=0.046) and the levels of the value of CA125 ((90.24 ± 18.56) U/ml vs.(243.35 ± 20.45) U/ml;t =7.780,P =0.002).Compared with 40 cases of control group,elevated CA125 level showed no obviously statistical significance (t =5.348,P=0.22).Forty patients in CT and MRI were all single lesion,30 cases were solid neoplasm,the rest were cystic-solidary lesions or priority of cystic component,75％ lesions were more than 5 cm,9 cases of lesions contains calcification.In pre-enhanced CT and MR/scan the lesions showed iso-density or signal-intensity,mildly enhanced;Twenty-two patients with ascites and 11 cases with symptoms in the elevating of estrogen.Combined the results of CA125 and the apperaance of CT and MR/,the accuracy of the diagnosis in ovarian thecoma was 85％.Conclusion CT and MR/imaging combining with CA125 can improve the diagnosis accuracy of ovarian thecoma.which should be given priorities.

BACKGROUND:Xenogeneic bone structure and biological characteristics are similar to human bone tissue, and the xenogeneic bone has a decreased antigenicity after physicochemical treatment, with a natural porous structure and rich source, and can be kept for a long time, which is considered to be an effective way to solve the shortage of the autogenous bone and al ograft bone.
OBJECTIVE:To compare the physical and chemical properties of xenogenic bone materials prepared by two different methods.
METHODS:Sheep cancellous bone treated with chemical method was placed into the muffle furnace at 1 000 ℃for 2 hours to prepare calcined bone. Another cancellous bone was placed into an 80 ℃ refrigerator for 4 weeks and then placed into a vacuum instrument to prepare freeze-dried bone. Cancellous bone rinsed with ultra-pure water served as controls.
RESULTS AND CONCLUSION: Three groups of samples retained three-dimensional porous structure which similar with human bone tissue under microscopic observation. The framework was stil intact, with a smal pore of 55-650μm and high porosity of 65%-80%. For the calcined bone, the toughness was decreased and the brittleness increased significantly, but the freeze-dried bone had a little changes in the mechanical properties. Through diffraction analysis, hydroxyapatite was the main composition of the three groups. However, there was a smal amount ofβ-tricalcium phosphate in the calcined bone. Spectrum analysis confirmed that calcium and phosphorus content in these three groups were al close to the human body. The results suggest the cancellous bone treated with these two methods is similar to human bone structure, and the major elements are close to the body. In addition, the cancellous bone after processing has enough smal pore and higher porosity. However, calcination process has a more influence on the mechanical property of scaffold materials, and the freeze-dried bone has a little change but the antigen cannot be completely removed that can reach the basic requirements.

BACKGROUND:Many in vivo and in vitro experiments indicate that implantation of exogenous basic fibroblast growth factor can significantly promote the process of bone formation, but the in vivo degradation of exogenous basic fibroblast growth factor affects the therapeutic efficacy.
OBJECTIVE:To observe the effects of basic fibroblast growth factor-transfected mesenchymal stem cells which transfected using molecular biology techniques combined with al ogeneic bone in the repair of critical-size bone defects in sheep.
METHODS:Al ogeneic bone with basic fibroblast growth factor-transfected bone marrow mesenchymal stem cells, bone marrow mesenchymal stem cells combined with al ogeneic bone material stents, al ograft bone material,β-tricalcium calcium material were respectively implanted into critical-size bone defects in sheep. After 4, 8 and 12 weeks, histological and immunohistochemical staining was performed.
RESULTS AND CONCLUSION:At 12 weeks after implantation of al ogeneic bone with basic fibroblast growth factor-transfected bone marrow mesenchymal stem cells as tissue engineering bone, there were many cartilage-like structures in the operative binding region and a large amount of osteoblast-like cells in the center of operative region, and there was more material degradation in the entire operative area as compared with other groups;there were fibrous connective tissues ful of the pores, and osteoclast-like cells were commonly seen around the implant material;bone sialoprotein and col agen type Ⅰ expression were strongly positive. In the other three groups, although the cartilage-like structure appeared in the binding region, dead bone structure was found in the central area, and bone sialoprotein and type Ⅰ col agen expression was weak. These findings indicate that al ogeneic bone with basic fibroblast growth factor-transfected bone marrow mesenchymal stem cells can basical y repair critical-size bone defects in sheep.

Vibrio vulnificus infection has a high disability rate and fatality rate. This paper summarized the diagnosis and treatment of a case of Vibrio vulnificus sepsis to help clinicians in the early detection and optimization of treatment options for such infections, thereby providing a clinical reference for related research. In September 2022, a case of sepsis caused by Vibrio vulnificus infection was admitted to the Emergency Department of Hainan Hospital of Traditional Chinese Medicine. Clinical treatment was conducted, and the report was analyzed. Meanwhile, Vibrio vulnificus literature was reviewed to analyze and summarize the treatment methods of Vibrio vulnificus sepsis. The 61-year-old patient was treated in the Emergency Department from September 23 to October 8, 2022, during which bacteriological examination of pus and wound infection samples identified the infection as being caused by Vibrio vulnificus. Therefore, targeted treatment with meropenem injection plus levofloxacin injection was administered for the infection, and early CRRT (continuous renal replacement therapy) was implemented to control the inflammatory cytokine storm of sepsis, and surgical debridement treatment was performed. After the patient's condition stabilized, the patient was transferred to the vascular surgery department, where two debridement + left lower limb skin grafting procedures were performed on October 27 and November 19. Then a third debridement + left lower limb third skin grafting + toe amputation was performed on December 10, the patient was discharged with improved condition post-surgery. At present, the patient can live independently and can move the affected limb autonomously. In clinical diagnosis and treatment of sepsis caused by Vibrio vulnificus infection, attention should be paid to the inflammatory cascade reaction. CRRT can eliminate inflammatory factors in the early stage, sensitive antibiotics for anti-inflammatory, surgical debridement interventional treatment, and multi-disciplinary linkage can be initiated to treat patients with Vibrio vulnificus sepsis.
