Chinese Journal of Ocular Fundus Diseases 2008;24(2):103-106
Objective To estimate the quality and efficacy of the academic thesis of compound anisodine in traumatic optic neuropathies(TON)treatment. Method We searched Chinese database last or"blunt trauma"as key words,and analyzed them using the standard of evidence-based medicine(EBM).Result 6 RCTS with a total of 415 eyes included are retrieved,and the OR value is 6.54 with a 95%CI of[4.14,10.35],P<0.00001,the difference is significant;sub-category analyses are made and both show significant difference(P<0.0001). Conclusion The existing evidence supports that prognosis of TON is better when compound anisodine are adopt in treatment,and this effect is significant in steroid treatment.Compound anisodine can be used alone for TON treatment.However.because there are only 6 thesis are retrieved and all of them have methodological short-comings,the evidence is not convincing.There is an urgent need of well-planed,large-scale and multiple-center studies to assess the role of compound anisodine in traumatic optic neuropathies treatment.
6.Study on the relationship of omentin-1 in coronary heart disease patients with different glucose tolerance
The Journal of Practical Medicine 2014;(4):542-545
Objective To investigate the relationship between omentin-1 and Coronary heart disease in different glucose tolerance populations. Methods Serum omentin-1 levels were determined by ELISA in 143 subjects with normal glucose tolerance,impaired glucose tolerance with CHD, type 2 diabetes mellitus with CHD. The relationships between omentin-1 and waist- to-hip ratio, body mass index (BMI), blood Glucose, serum insulin,HOMA-IR and blood fat were also explored.Coronary artery stenosis was screnned by coronary interventional angiography and assessed by Gensini scoring system. Results Serum omentin-1 levels were all lower in T2DM and IGT subjects than those in control subjects (P<0.01). Serum omentin-1 was correlated positively with high density lipoprotein-cholesterol (P < 0.01),and inversely with body mass index,waist-hip ratio,diastolic blood pressure, triglyceride,fasting blood glucose,fasting insulin,HbA1c,[w1]and insulin resistance(HOMA-IR)(P<0.05 or P <0.01).Omentin-1 levels was negative related with Gensini coronary artery score (P < 0.01). Multiple linear regression showed body mass index,HOMA-IR,diastolic blood pressure were independently associated with omentin-1 levels (P<0.05 or P<0.01). Conclusions Serum omentin-1 levels, associated with fat,insulin sensitivity, are likely to play an important role in insulin resistance and the development of CHD in populations with different glucose tolerance.
7.Antiepileptic drug trials with greater attention to daily clinical practice and special epilepsy syndromes
Neurology Asia 2007;12(Supplement 1):30-32
Most of the present antiepileptic drug trials focus on efficacy and short-term safety with limited
information relevant for daily clinical practice, such as spectrum of efficacy, effective dose, titration
method, drug interactions, and long-term outcome. Antiepileptic drug trials more akin to daily clinical
practice should also be emphasized in future trials. There are, limited randomized control trials for
certain seizure types or epilepsy syndromes, such as Lennox-Gastaut syndrome and severe myoclonic
epilepsy in infancy. The author proposed self-controlled “class S” study in patients who has well-defined
epilepsy syndrome with homogeneity in evolution of illness and high frequency of seizures.

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.
