Objective To analyze the clinical features of Hashimoto thyroiditis with thyroid cancer, and provide scientific basis for clinical diagnosis and treatment. Methods The clinical data of 87 patients of Hashimoto thyroiditis with thyroid cancer and 105 patients of Hashimoto thyroiditis were retrospectively analyzed. Results The rates of Hashimoto thyroiditis with thyroid cancer in age <30, 30-39, 40-49, 50-59 and≥60 years were 1/3, 47.5%(29/61), 51.4%(38/74), 36.0%(18/50) and 1/4. The rates of Hashimoto thyroiditis with thyroid cancer in patients of age 30-39 years and 40-49 years were higher than that in patients of age ≥60 years, but there were no statistical differences (χ2=0.327 and 0.418, P>0.05). There were statistical differences in total thyroxine (TT4), thyroid stimulating hormone (TSH), thyroglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) levels between Hashimoto thyroiditis with thyroid cancer and Hashimoto thyroiditis, there were statistical differences (P<0.05 or <0.01). Multiariable Logistic regression analysis result showed that the decreased serum level of TT4 and the increased levels of TSH, TgAb and TPOAb were the correlated factors of Hashimoto thyroiditis with thyroid cancer (P<0.05 or <0.01). Conclusions Low level of TT4 and high levels of TSH, TgAb and TPOAb may increase the risk of Hashimoto thyroiditis with thyroid cancer. The 30-49 years male patients with Hashimoto thyroiditis should be highly suspected of the possibility of merger thyroid cancer.

Objective To investigate the correlation between JAK2V617F mutation and clinical characteristics in patients with myeloproliferative neoplasm(MPN) in Xinjiang area.Methods The correlation between JAK2V617F mutation and clinical characteristics about gender,age,nationality,leukocyte counts,platelet counts,hemoglobin and LDH levels,complications of thrombosis,bleeding and vascular disease in 134patients with MPN were analyzed. Results 73.1％ (98/134) JAK2V617F mutation was found in patients (51with PV,66 with ET, 17 with IMF). Compared with negtive mutation, the rata of ≥60 years was significantly higher in positive group [78.6 ％(77/98)vs25.0 ％(9/36)(χ2=32.867,P＜0.001)]. Patients harboring JAK2V617F mutation have higher leukocyte counts[(15.9±8.2)×109/L vs (9.6±5.3)×109 L,t=4.296,P＜0.001],hemoglobin levels [(156.4 ±44.9)g/L vs (133.8 ±44.1)g/L,t=2.590,P =0.011],incidence of thrombosis [73.5 ％(72/98)vs22.2 ％(8/36),χ2=28.740,P＜0.001)] and vascular diseas [81.6 ％(80/98)vs25.0 ％(9/36),χ2=37.859,P＜0.001)]. There was no significant difference in gender, nationality, platelet counts, LDH levels and bleeding complications between JAK2V617F positive and negative patients. Conclusion There is a correlation between JAK2V617F mutation in MPN and age,leukocyte counts,hemoglobin levels,thrombosis and vascular disease complications.

Aim To establish a reliable and practical rat model with hypertension induced by DOCA-Salt.Methods One week after nephrectomy,the rats were subcutaneously injected with DOCA (30 mg?kg-1) once a week and fed with a chaw with 10 g?L-1NaCl plus 2 g?L-1 KCl in drinking water for 4 weeks. Blood pressure was measured and,urine was collected for measurement of volume(UV),UNaV,UClV,UKV,UCaV and pH values,once a week. SGPT,CREA,SUGA,TRIG,CHOL,INS,ALD,ADH were measured in circulating blood samples. Kidney morphological changes and Na+,K+-ATPase activity of the renal tubular epithelial cells were also examined. Results Blood pressure,UV,UNaV and UClV were increased and histopathological changes of the kidney such as glomerulus sclerosis and tubular pachynsis were observed in the DOCA-Salt rats. Whereas UKV,UCaV,urine pH values,SGPT,CREA,SUGA,TRIG,CHOL,INS,ALD and ADH were not changed. In contrast,Na+,K+-ATPase activity of the renal tubular epithelial cells was decreased. Conclusion DOCA-Salt is a reliable hypertensive model with sodium retention.

Objective To study the short-term outcome of transforaminal posterolateral endoscopic discectomy and radiofrequency annuloplasty in patients with discogenic low back pain. Methods A total of 25 patients with discogenic low back pain,who were diagnosed by provocative discography,received transforaminal posterolateral endoscopic discectomy and radiofrequency annuloplasty in our hospital. The VAS scores determined before and 6 months after the operation were compared in the patients. Their MacNab scores were also evaluated at 6 months postoperation. Results After the surgery,2 patients who had ruptured intervertebral discs (L5-S1) developed sunburn syndrome,and then was relieved by pulsed electrical stimulation for one week. The patients were followed up for 6-10 months,during which no other postoperative complications occurred. The mean VAS score of this series decreased significantly after the treatment,and kept being reduced in 6 months [preoperation:6.24?0.97,1,3,6 months after the operation:0(0~2); Kruskal-Wallis rank-sum test,H=61.680,P=0.000]. Four patients showed lower limbs pain before the treatment and were relieved after the surgery. The evaluation of MacNab score showed excellent in 11 pateints,good in 12,and fair in 2,suggesting an effective rate of 92.0%(23/25). Conclusions Transforaminal posterolateral endoscopic discectomy plus radiofrequency annuloplasty is effective for discogenic low back pain in a short term.
