Uremia caused secondary hyperparathyroidism is one of the common and serious complications caused by uremia. Surgery treatment is effective. Total parathyroidectomy plus forearm transplantation is more commonly used because of exact outcomes and easy monitoring. It is necessary to be fully prepared be-fore operation,particularly to clarify the location of parathyroid gland. Yet each surgical method has its re-lapse rate.

This paper reports a study of renal microcirculation in rabbits with glycerol-induced acute renal failure by using the microsphere technique, transmission and scanning electron-microscopy as well as morphemetry. In the initial phase of acute renal failure, there was microcir-culatory ischemia, and the changes were parallel with functional changes following glycerol injection, the renal microcirculation showed marked structureal changes. The results indicated that renal microcirculation should be given early.

Objective To evaluate thetherapeutic effect of sodium deoxyribonucleotide injection at Zusanli point for chemotherapy-induced leukopenia in patients with lung cancer.MethodsA total of 116 chemotherapy-induced leukopenia patients with lung cancer were randomly divided into a therapy group and a control group, 60 in the treatment group and 56 in the control group. The patients in the treatment group were treated with sodium deoxyribonucleotide injection atZusnlipoint, and those in the control group were treated with vein injection of sodium deoxyribonucleotide.Results The total effective rate in the treatment group was significant higher than that in the control group (91.7%vs.76.8%;χ2=4.890,P=0.032). The effective rates on days 3,5,7 and 10 in the treatment group were also significant higher than those in the control group (on day 3: 51.7%vs. 32.1%,χ2=4.530,P=0.036; on day 5: 76.7%vs. 53.6%,χ2=6.840,P=0.018; on day 7: 85.0%vs. 67.9%,χ2=4.770,P=0.026; on day 10: 78.3%vs. 53.6%,χ2=7.960,P=0.011).Conclusion Sodium deoxyribonucleotide injection atZusanlipoint has definite efficacy for chemotherapy-induced leukopenia in patients with lung cancer.

Objective To define the expression of Shh/Gli1,the key elements of Hedgehog signaling pathway in papillary thyroid carcinoma(PTC) and to explore the relationship between the expression of Shh/Gli1 and clinical significance.Methods The expression of Shh and Gli1 was examined in 142 cases of PTC tissues and adjacent tumor thyroid tissues as control by immunohistochemistry.The relationship between the expression of Shh/Gli1 and clinical characteristics of PTC patients was analyzed.Results The positive rate of the cytoplasm Shh expression and the nuclear Gli1 expression was 64.1% and 47.9% ,respectively.Significant difference was found between normal thyroid tissues and PTC.The research showed that the expression of Shh/Gli1 was related to the tumor size,clinical stages and lymph node metastasis,Shh was more significantly related to the tumor size(P ＜0.01) and Gli1 was more significantly related to the lymph node metastasis (P ＜ 0.01).Conclusions Varying expression of the main ligand Shh and transcription factor Gli1 in Hedgehog signaling pathway was found in PTC.The expression of Shh/Gli1 was related to the tumor size,clinical stage and lymph node metastasis,indicating that the aberrant activation of Shh signaling pathway plays some roles in PTC.Shh/Gli1 may be indicators for prognosis and ideal targets for therapy against PTC.

Objective To approach the guide of ultrasound-guided minimally invasive biopsy technique in diagnosis and treatment of thyroid diseases. Methods One hundred and seventeen cases (a total of 131 nodules, nodules 0. 5-1.5 cm in diameter, with an average diameter of approximately 0. 8 cm) with thyroid nodules , under Ultrasound-guided minimally invasive biopsy techniques from October 2008 to July 2009 were analyzed. Result One hundred and seventeen cases of patients with biopsy derived satisfaction were not ap-parent discomfort and complications after biopsy. Across 59 cases of surgical treatment in patients with biop-sy, and preoperative biopsy and postoperative pathologic is not fully consistent in only two cases, 58 patients without surgical treatment, who is combined with symptoms, palpation, serum thyroxine and color Doppler ultrasound and other laboratory examinations, and regularly review treated with symptomatic treatment, the symptoms, and color Doppler ultrasound imaging were much better under the treatment. 8 cases of patients in 117 cases of minimally invasive biopsy have cervical lymph node biopsy at the same time, biopsy patholo-gy and postoperative results are consistent with postoperative pathologic (7 cases of metastatic carcinoma, 1 case of reactive hyperplasia), accuracy was 100%. Conclusion Uhrasound-guided minimally invasive bi-opsy technique have important guiding for diagnosis and treatment of thyroid diseases, consistent with the high rate of clinical, especially for the preoperative diagnosis of small nodules, to avoid unnecessary over-treatment, can also reduce the misdiagnosis of thyroid cancer. While this technology is simple, safe and ac-curate, which have clinical value in the thyroid surgery.

Objective To discuss the effective factors and metastasis rules of cervical lymph node of papillary thyroid microcarcinoma,aimed to provide references for indications and range of lymph node dissection.Methods Reviewed the clinical information and pathological material of primary treatment of 1 180 cases of papillary thyroid microcarcinoma patients in China-Japan Union Hospital of Jilin University from June 2008 to December 2011 by retrospective analysis,futher summared cervical lymph node metastasis rules and effective factors.Results The lymph node metastasis rate of 1 180 patients with papillary thyroid microcarcinoma was 29.6％,which of these of the central and lateral region were 26.4％ and 15.2％.Central region lymph nodes metastasis rates in male and female were respectively 44.9％,21.8％ (P ＜ 0.05),and were 39.8％,9.0％ in lateral region (P ＜ 0,01).Lymph node metastasis rates of patients whose age ≤45years old and ＞45 years old were 30.3％,17.9％ (P ＜0.05).The lymph mode metastasis rate which diameter of tumour(D) ≤0.5 cm or 0.5 cm ＜ D ≤ 1 cm in central region were 20.2％,33.2％ (P ＜ 0.05).The lymph node metastasis rate of single and more nidi respectively were 15.7％,45.0％ in central region.The lymph node metastasis rate of tumors invasion or not were 44.4％ and 14.2％ in central region (P ＜0.05).The metastasis rates were 45.5％ and 4.3％ in the lateral region when the lymph node infringe or not in central region.Conclusions Lymph node metastasis happens relatively more common in papillary thyroid microcarcinoma patients with the factors such as male,young age,multiple nidi,long diameter of tumor and invasion of tumor envelope.So when doctors establish the indications and range of lymph node dissection,it's need to pay attention to the high risk factors seriously which effect lymph node metastasis of papillary thyroid carcinoma,and establish the lymph node dissection strategy individually.
