Background The pathogenesis of pterygium has been in the study.Relative molecular biology study showed that pterygium is a tumor-like lesion,and based on overseas literatures,human papillomavirus (HPV) is positively expressed in 100％ patients with pterygium in some region.However,if this result is suitable for Chinese patients is unclear.Objective This study was to identify the role of human HPV in the pathogenesis of pterygia in Wuxi area.Methods Forty-eight pterygium specimens including 7 recurrent pterygia and 41 primary pterygia were collected during the operation,and these patients were from Wuxi area.Two cervical carcinoma specimens and 2 conjunctiva specimens from normal donors were obtained as positive control and negative control respectively.The fluorescent quantitative polymerase chain reaction (FQ-PCR) was used to detect HPV DNA of specimens.Results The amplified curves of HPV 6,11 of pterygium specimens,cervical carcinoma specimens and normal specimens were all below the positive quality control curve,but the amplified curves of HPV16,18 were above the quality control curve in cervical carcinoma specimens; while those of pterygium specimens and normal conjunctival specimens were all below the quality control curve.HPV16/18 was identified in 2 cervical carcinoma specimens,but no HPV6/11 was detected in 2 cervical carcinoma specimens.However,HPV DNA expression in primary and recurrent pterygias were absent.Conclusions According to these results,HPV is not the primary cause for the pathogenesis of pterygium in Wuxi region.

Objective: To discuss the effect of group counseling on the self-control of male adolescents drug addicts. Methods: 90 male adolescents drug addicts who accepted group counseling were identified as test group, while another 97 male adolescents drug addicts who accepted no intervention as control group. Self Control Scale developed by Grasmick in 1993 was used to assess the outcome. Results: The total scores in the test group decreased from 52.06?6.67 to 47.68? 8.67, and all dimension scores were at significant level (P

Objective To compare the clinical diagnoses with autopsy findings and evaluate the frequency of misdiagnosis.Methods The findings of 356 cases who were autopsied in our department due to medical treatment dispute during the period of 1988 to 2007 were retrospectively analyzed.The clinical diagnosis and autopsy findings,sex and age of the death,length of hospitalization,the hospital department,distribution of death disease and the rank of hospital were analyzed.The concordance between diagnosis before death and at autopsy was calculated.Results In 162 cases(45.5%),the autopsy findings confirmed the clinical diagnosis.In 101 cases(28.4%),the clinical diagnosis suggested by clinicians were discordant with the autopsy findings.In 63 cases(17.7%),some diagnoses made by clinicians were proved by autopsy,and in 30 cases(8.4%),the clinical and postmortem diagnosis were beyond comparison.The most frequently misdiagnosed diseases were from cardiovascular and respiratory diseases,and among them,cardiomyopathy,aortic atherosclerosis and pneumonia were most common.Conclusion Autopsy is not only helpful for the management of medical dispute,but also beneficial to reduce the misdiagnosis in clinical practice.

Objective To investigate the level of mental health and effect of psychological rehabilitation on paraplegic patients. Methods 38 paraplegic patients were randomly divided into control group (n=19) and treatment group (n=19). Both groups received physical therapy and occupational therapy, while the treatment group received psychotherapy in addition, once a week for 3 weeks. Their mental health level was assessed with Self-reporting Inventory. Results The psychological problems occurred was ranked as somatization, anxiety, fear, interpersonal sensitivity, depression and obsession from more to less. The scores of each factor reduced after treatment (P<0.05). Conclusion The paraplegics are in poor mental health condition, so more psychotherapy intervention should be taken to improve their rehabilitation effect and quality of life.

?AIM:To investigate the correlation between dry eye and different degrees of diabetic retinopathy ( DR ) in type 2 diabetic patients.?METHODS: In the cross-sectional study, 340 patients (340 eyes) with type 2 diabetes were enrolled. Tear film function tests including tear meniscus height, tear film breakup time ( BUT ) , fluorescein staining, Schirmer Ⅰtest were performed followed by surveying questionnaires about dry eye. Retinal status was evaluated by retinal color photography and indirect ophthalmoscopy exam with dilated pupils to evaluate DR and whether companied by macular edema.?RESULTS:The prevalence of dry eye was 49. 41%. The mean duration of diabetes in patients with dry eye was 11.15±7.07a, while 6.92±5.45a without dry eye(P<0.01). Dry eye had the positive correlation to the development of DR. The incidence of dry eye in people with mild nonproliferative diabetic retinopathy ( NPDR ) , moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR) was 1. 097 times, 1. 724 times, 2. 86 times and 5. 43 times respectively, compared with people without DR. The occurrence of dry eye in people with macular edema increased by 3. 697 times compared with people without macular edema.?CONCLUSION: Dry eye was more prevalent in people with type 2 diabetes. The incidence of dry eye increased gradually with the occurrence and development of diabetic retinopathy.

OBJECTIVETo investigate the value of iodine-131 therapy for hyperthyroidism complicated hyperthyroid heart disease(HHD) induced by Graves' disease or Plummer disease.

METHODSTotally 40 HHD cases who were confirmed in our department from 2009 to 2010 were enrolled in this study. All patients received serum thyroid hormones and associated antibodies tests, 12-lead electrocardiogram, and/or thyroid imaging before and after iodine-131 therapy to access the treatment effectiveness.

RESULTSAmong 31 patients with HHD due to Graves' disease and 9 due to Plummer disease, iodine-131 treatment resulted in euthyroidism in 15 and 5 patients and hypothyroid in 7 and 2 patients, while 9 and 2 remain hyperthyroid, respectively.Serum free triiodothyronine, free thyroxine, and thyroid-stimulating hormone were statistically significant(P<0.05) before and after iodine-131 therapy, while no significant difference for serum thyrotrophin receptor antibody, antithyroid peroxidase autoantibody, and anti-thyroglobulin antibody.Atrial fibrillation was the most common cardiac complication of hyperthyroidism(n=25, 62.5%) .The remission rate after iodine-131 treatment was 76.0%.

CONCLUSIONIodine-131 therapy can effectively and timely control hyperthyroid in HHD patients.
