Objective To analyze the clinicopathologic features of primary cutaneous CD30 positive lymphoproliferative disorders. Methods A clinical, pathological and immunohistochemical analysis was carried out in 4 cases of lymphomatoid papulosis and 5 cases of primary cutaneous anaplastic large cell lymphoma. Results Lymphomatoid papulosis was divided into 3 subtypes, A, B and C. The lymphomatoid papulosis of subtype A was pathologically characterized by pleomorphic anaplastic large cells or Steinberg-reed cells scattered or patchly distributed among many inflammatory cells; subtype B showed pathological changes characteristic of granuloma fungoides, and manifested as a broad infiltration zone of lymphocytes in dermis with scattered small- to middle-sized atypical gyrus-like lymphocytes; subtype C was characterized by a diffuse distribution of anaplastic large cells and could clinically subside spontaneously. Primary cutaneous anaplastic large cell lymphoma clinically manifested as subcutaneous nodules or papules, and was pathologically characterized by large, pleomorphic, round or ellipse cells with plentiful, eosinophilic or bicolor cytoplasm, large nuclei and obvious nucleoli. The neoplastic cells characteristically expressed CD30 antigen in both lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma, and all the cases showed a favorable prognosis.Conclusions Primary cutaneous CD30 positive lymphoproliferative disorders are a spectrum of cutaneous T cell lymphoma with favorable prognosis, and a synthetic analysis of clinical, histopathological and immunohistochemical findings is beneficial to the diagnosis of these entities.

Objectives To investigate the clinical features of Guillain-Barré syndrome (GBS) in children from Shen-zhen. Methods The clinical manifestations, results of electrophysiological tests and prognosis of 28 GBS patients from July 2002 to July 2012 were retrospectively analysed. Results Of 28 children, 16(57.1%) had preceding acute upper respiratory infection for 3-14 days but no patient had acute gastroenteritis. One had received HBV vaccination in 2 weeks before the onset of GBS. The peak season for GBS is spring. According to the clinical presentations and the neurophysiological results 17 patients had demyelinating neuropathy, 5 acute motor axonal neuropathy, 2 acute motor sensory axonal neuropathy, 3 Miller-fisher syndrome, and 1 polyneuritis cranialis. 14 (50.0%) patients suffered from pain in limbs which is the most nota-ble symptom in the early stage. Intravenous immune globulin (IVIG) and steroids were given during the acute phases in the majority of the patients, and assisted ventilation was performed in 2 patients due to respiratory muscle paralysis. No diffe-rence was found in Hughes scores, average hospitalization durations, and the prognosis between patients with GBS variants patients and patients with classic GBS. Conclusions Children with GBS in Shenzhen area have different clinical features.

Objective: The aim of this study was to evaluate whether there is an association between Parkinson’s
disease (PD) and colorectal cancer in Taiwan. Methods: This was a case-control study using claim
data of the Taiwan National Health Insurance Program. There were 64,619 subjects aged 20-84 with
newly diagnosed colorectal cancer as cases and 64,619 randomly selected subjects without colorectal
cancer as controls from 2005 to 2011. Both cases and controls were matched by sex, age, comorbidities,
and index year of diagnosing colorectal cancer. Subjects who were diagnosed with PD within 5 years
of diagnosing colorectal cancer were excluded. The multivariable logistic regression model was used
to estimate the adjusted odds ratio (OR) and 95% confidence interval (95% CI) for risk of colorectal
cancer associated with PD. Results: After adjusting for confounding factors, the multivariable logistic
regression analysis revealed that the adjusted OR of colorectal cancer was 0.69 for subjects with PD
more than 5 years before index date (95% CI 0.59, 0.81), as compared with subjects without PD.
Conclusion: PD is associated with reduced odds of colorectal cancer. Further research is needed to
elucidate the mechanisms underlying our findings.

Obesity is becoming a chronic epidemic worldwide. Persistent obesity, in addition to triggering changes in skeletal muscle function and structure, may also lead to the occurrence of skeletal muscle atrophy, that maybe associate with autophagy and ubiquitin protea-some, interleukin-6, leptin, adiponectin, interleukin-10, tumor necrosis factor-alpha, growth hormone, angiotensin II, glucocorticoid, ad-vanced glycation end-product and myostatin, etc.

Objective To study the expression and value of CXCR1 and CXCR2 on neutrophils, CD14~+ monocytes and CD3~+ T lymphocytes of peripberol blood of ankylosing spondylitis(AS)patients and to investigate the correlation between CXCR1,CXCR2 and disease activity.Methods A case control study was designed and enrolled 30 active AS,30 active rheumatoid arthritis(RA)and 30 healthy controls.The levels of CXCR1 and CXCR2 expression on neutrophils,CD3~+ T cells and CD14~+ monocytes of peripheral blood of the patients and healthy controls enrolled were measured and analyzed by flow cytometry by measuring the mean fluorescence intensity(MFI)channel.The correlations between the level of CXCR1 and CXCR2 anti disease activity or functional index of AS such as BASDAI,BASF1,ESR and CRP were analyzed.Results The MFI of CXCR1 expression on CD3~+ T lymphocytes of peripheral blood was significantly higher in AS patients (41?24)than that in RA patients(18?10)and healthy controls(19?7)(P

Objective To establish a new model of cardiac arrest (CA) in rats by transcutaneous electrical epicardium stimulation. Method Two acupuncture needles connected to the anode and cathode of a stimulator were transcutaneously inserted into the epicardium as electrodes. The stimulating current was steered to the epicardium and the stimulation was maintained for 3 minutes to induce CA. Cardiopulmonary resuscitation (CPR) was performed at 6 minutes after a period of nonintervention. Results The success rate of induction was 12/20 at the current intensity of 1 mA; and reached 20/20 when the current intensity was increased to 2 mA. The average time from the electrical stimulation to CA induction was (5. 10 ± 2. 81) seconds. When the electrical stimulation stopped, 18/20 rats had ventricular fibrillation and 2/20 rats had pulseless electrical activity. CPR was performed for averagely 207.4 ( ± 148.8) seconds. The restoration of spontaneous circulation was 20/20. The death rate within 4 hours after CA was 5/20, and the 72-hour survival rate was 10/20. There were only two cases of complications, a minor muscle contraction and a minor lung lobe injury. Conclusions The model of CA in rats induced by transcutaneous electrical epicardium stimulation is a stable model that requires low-intensity current and has fewer complications.
