Objective To describe the morphological characteristics of Porocephalus taiwana sp. nov., discuss its pathogenic features and the method of etiological diagnosis of the new disease. Methods Fecal sedimentation concentration was used to collect nymphs from the patient's watery stool for species identification. Clinical information was collected for determining the pathogenic features of the new infection. Results A new pathogenic pentastomid Porocephalus taiwana sp. nov. is discovered and a new disease-porocephaliasis taiwana-is nominated. With the findings from this case it is proposed that the traditional visceral pentastomiasis should be divided into two subtypes, Encystic and Excystic. According to the pathological features, this case belongs to the excystic visceral pentastomiasis. Conclusion Porocephalus taiwana sp. nov. is a new pathogenic pentastomid infecting humans. Porocephaliais taiwana belongs to a novel type (excystic) of visceral pentastomiasis.

Objective As a classical approach for hyperthermic ablation,microwave ablation (MWA) has been widely used in the treatment of tumors that cannot be removed by traditional surgery.MWA devitalizes the neighboring tissue and kills tumor cells by thermal diffusion.In the last two decades,this technique has been improved for treating malignant bone tumor in our institute.In situ ablation has already replaced en bloc resection and achieved satisfactory treatment outcomes.This study explores whether tumor cell death induced by MWA would cause the release of immunogenic tumor antigens and tumor-specific immune responses.Methods Three models of MWA were established using osteosarcoma cell lines from the mouse,rat,and human,respectively.The expression of immunogenic molecules was measured during in vitro and in situ ablation with different ablation time and group design.Results The injection of tumor vaccines made from tumor cells or supernatant treated with in vitro ablation resulted in substantial inhibition of tumor cell growth in tumor-bearing animal models.The CDs + T cells induced by vaccines played a key role in the process.The effector cells released cytokines,IFN-γand TNF-α,to inhibit tumor cell growth and also trigger Fas/FasL-mediated apoptosis.Conclusions MWA-treated osteosarcoma cells can be used to induce specific antitumor immunogenic effects.Therefore,in situ MWA combined with immunotherapy provides an alternative treatment method for patients who have trouble due to their insensitivity to chemotherapy.

Objective:To investigate the expression of activin A in paraventricular nucleus (PVN)of the WKY rats and its influence in arterial blood pressure,and to clarify the mechanism of activin A in the regulation of arterial blood pressure by PVN.Methods:The WKY rats were selected.The expressions of activin A,ActRⅡA,ActRⅡB,and Smads mRNA in PVN of the WKY rats were measured by RT-PCR.The expression of ActRⅡA protein in PVN was detected by immunohistochemical staining.The microinjection of exogenous activin A into PVN was used to observe the changes of arterial blood pressure.The primary cultured PVN neurons from the WKY rats were divided into control group and activin A group.The mRNA expression levels of ActRⅡA,ActRⅡB,and Smads in the PVN neurons were analyzed by RT-PCR.Results:Activin A,ActRⅡA,ActRⅡB,Smad2 and Smad3 mRNA were expressed in PVN of the WKY rats.The ActRⅡ A protein expression in PVN was further confirmed by immunohistochemical staining.After microinjection of activin A or angiotensin Ⅱ (AgⅡ)into PVN,the mean arterial blood pressure was increased obviously compared with before treatment (P <0.05).Moreover,compared with control group,the expression levels of ActRⅡA and Smad3 mRNA in primary cultured PVN neurons of the rats in vitro were significantly increased (P <0.05).Conclusion:Activin A can regulate the arterial blood pressure in PVN in an autocrine or paracrine manner,which is related to ActRⅡA-Smad3 signal pathway.

To investigate the role of intercellular adhesion molecule 1(ICAM 1) in the pathogenesis of bacterial keratitis,22 rats were randomly divided into bacterial keratitis group and control group. A specific staining of corneal epithelial cells, stromal keratocytes and endothelial cells for ICAM 1 was carried out by using monoclonal antibody to ICAM 1 and immunohistochemical staining techniques. The results showed that ICAM 1 expressed a low level in the corneal epithelial cells, stromal keratocytes and endothelial cells in the control group(-~+), while its expression was strong in the keratitis group (~). The difference between two groups was statistically significant ( P

Objective:To evaluate the clinical outcomes of patients with single spinal metastasis of thoracic, lumbar or sacral vertebra treated with microwave ablation in situ.Methods:For 28 patients with single spinal metastasis of thoracic, lumbar or sacral vertebra, detailed and personal surgical plans were carried out. Instead of en bloc resection, hyperthermia ablation in situ was performed followed by strengthening procedures under the guidance of G-arm fluoroscopy machine. Intraoperatively, spinal cord and nerve root were properly protected. The bone defects were reconstructed by bone cement after the diseased lesions were revomed. All patients were followed up for almost 1 year postoperatively. During follow-up, X-ray and MRI images were obtained, and the level of pain and neurologic outcomes were also examined.Results:All 28 patients successfully received microwave ablation in situ. The average ablation time was approximately 8 minutes and the average amount of bone cement implanted was approximately 10.5 ml. The pain scores of digital pain classification before and 3 months after operation were 7.86±1.58 and 3.07±1.89( P<0.05). The postoperative neurological function of 22 patients was improved than that before operation. No significant changes were observed in 5 patients. The neurological function of the affected limb was relieved, whereas the symptoms of the healthy limb were slightly worse in the remaining case. Conclusions:Microwave ablation in situ is a feasible and effective surgical method for single spinal metastasis of thoracic, lumbar or sacral vertebra. It might possess many advantages, such as clear surgical field, smaller incisions, less bleeding, and safe margins during the operations. Further more, it could significantly relieve pain, restrict tumor growth, and improve the quality of life of patients. It is an innovative and distinctive therapeutic alternative for single spinal metastasis, which deserves widespread application.

BACKGROUND:Surgical treatment is often required for fractures of the cervical vertebrae. Anterior interbody fusion technology is stil the main method for the treatment of cervical degeneration or traumatic instability. Here, the self-made oval al ogeneic bone pad can adapt to different height and width of the intervertebral space, in line with the physiological shape of the intervertebral space. OBJECTIVE:By comparison with autogenous iliac crest bone, to evaluate various types of self-designed al ogeneic bone pads on anterior cervical interbody fusion. METHODS:From January 2009 to December 2013, 58 patients with cervical disc herniation were enrol ed and subjected to cervical discectomy and anterior cervical interbody fusion. According to different bone grafts, these patients were divided into al ogeneic bone pad and autogenous iliac bone groups. The course of disease was 12 to 24 months. The postoperative effect was measured by Japanese Orthopaedic Association (JOA) score, cervical fusion rate, fusion time, operative time, blood loss and rejection rate. RESULTS AND CONCLUSION:At 6 months postoperatively, the JOA score of two groups had no significant difference at 6 months after treatment (P>0.05);the cervical fusion rates were 83.7%and 87.8%, respectively, in the al ogeneic bone pad and autogenous iliac bone groups, with no significant difference (P>0.05). Fusion time was higher in the al ogeneic bone pad than in the autogenous iliac bone group (P<0.05). The internal fixators in the two groups were firmed without loosening, and there was no rejection during the fol ow-up. Compared with the autogenous iliac crest bone, anterior cervical interbody fusion with al ogeneic bone pad can achieve satisfactory effects, which can be better for intervertebral fusion and cannot induce pain due to bone cutting.
