Objective To analyze the assessment results of iodine deficiency disorders(IDD) External Quality Control Laboratories at all levels in Guizhou province and the network operation to further standardize and improve the laboratory, improve network performance, provide reliable laboratory quality assurance for epidemiological surveillance and control of IDD and reliable decision-making. Methods The results of different level of IDD labs in Guizhou that took part in the entire country's IDD lab exo-network quality control examination of 1999 - 2008, which organized by the nation iodine deficiency disorder reference lab were analyzed. Results In the past 10 years, except the provincial laboratory examination results of urinary iodine in 2000 was failed, the other results were all qualified in the rest 9 years;iodized salt examination results were qualified. The urinary iodine laboratory response rate of Guizhou provinces and municipalities(state, district), from 1999 to 2002, were 88.9%(8/9), 66.7%(6/9), 77.8%(7/9), 66.7%(6/9), respectively, and the rate was stable at 100% from 2003 to 2008. Qualifying rate reached 100% in 2007, the remaining 9 years were 33.0%(3/9) - 88.9%(8/9). The iodized salt laboratory response rates were 100%(9/9) in 2000 - 2008. The pass rates were 77.8%(7/9), 88.9%(8/9),77.8%(7/9) from 2001 to 2003, 88.9%(8/9) in 2007, and the remaining 5 years 100%. Response rate of iodized salt laboratory at the county level that participated in the External Quality Control were 66.7% (20/30), 90.0%(27/30), 80.0% (24/30), 96.7% (29/30) from 2000 to 2003, respectively, and 2006 was 96.7% (29/30), and the remaining four years were all 100% (30/30). The pass rates in 2000 - 2008 were between 53.3% (16/30) -93.3%(28/30). Conclusions The accuracy of test results of external quality controls and the normal operation of the network at all levels of laboratories is closely related to the IDD laboratory conditions, detection techniques, and the degree of attention of relevant departments and professional bodies.

BACKGROUNDIf the emphysema lesions are not symmetrical, unilateral lung volume reduction surgery (LVRS) can be carried out on the more severe side. The aim of this research was to evaluate the feasibility and effects of LVRS performed simultaneously with resection of pulmonary and esophageal neoplasms.

METHODSForty-five patients with pulmonary neoplasm and 37 patients with esophageal neoplasm were randomly assigned to group A or group B. In group A, LVRS was performed simultaneously on the same side as thoracotomy. In group B, only tumor resection was performed. The nonfunctional lung area was determined by preoperative chest computed tomography and lung ventilation/perfusion scan. The lung volume removed was about 20% to 30% of the lobes on one side. Preoperative and postoperative indexes including pulmonary function testing variables, arterial blood gas analysis variables, dyspnea scale, 6-minute walk distance, etc., were compared between the groups.

RESULTSThere were no surgical deaths in this study. The postoperative forced vital capacity in 1 second, PaO2, PaCO2, dyspnea scale, and 6-minute walk distance were improved significantly in group A, whereas these indexes did not change or decreased slightly in group B.

CONCLUSIONSFor tumor patients who have associated emphysema, simultaneous LVRS not only increases the chance of receiving surgical therapy, but also improves the postoperative quality of life of the patient. LVRS has expanded the surgical indication for tumor patients.

Objective To explore rationale and clinical application of simplified modified radical thyroideetomy for differentiated thyroid carcinoma.Methods From Jan.2007 to Jun.2010,349 cases of differentiated thyroid carcinoma received simplified operative procedure based on standard modified radical thyroidectomy.The simplified procedure took a low small collar incision(about 10-12 cm).In separating upper and lower skin flaps,subcutaneous tissues covering posterior triangle of neck and posterior edge of sternoeleidomastoid muscle were spared to protect sensory nerves.Subtotal thyroidectomy Was performed to resect the affected lobe,isthmus,and the majority of opposite lobe without considering the size of primary tumor or whether metastasis to the neck lymph nodes happened.Soft tissues of the mainly metastatic areas(Ⅱ a、Ⅲ、Ⅳ、Ⅴb)were cleared.The accessory nerve was not exposed routinely to avoid stimulation.Lymph nodes metastasis in different areas was recorded respectively.Complications in different operative modes were compared.Results Compared with standard modified radical thyroidectomy,the simplified mode had shorter scar-and no limit of neck mobility.Because of muscles and nerves pemervation,movement dysfunction and abnormal sensation of neck and shoulder decreased obviously.The operation duration was shortened.Cervical lymph node status Was evaluated,which provided basis for prognosis judgment and comprehensive treatment.Conclusions The simplified modified radical procedure has the benefit of decreased trauma while maintains the similar recurrence rate compared to modified radical thyroidectomy.It improvs the life quality of patients.This procedure fits the principle of functional radical neck dissection better.

OBJECTIVETo explore the optimal methods for the reconstruction and preservation of the glans after partial penis resection in the treatment of early-stage penile cancer.

METHODSBetween January 2012 and June 2015, we treated 6 cases of early- stage penile cancer by partial penis resection, inner thigh skin graft, and glans reconstruction and followed them up for 0.5-3 years.

RESULTSThe length of the penis before and after operation was ([6.5 ± 1.2] vs [4.5 ± 1.8] cm) in the flaccid state and ([12.8 ± 2.3] vs [9.1 ± 2.1] cm) in the erectile state. The sense of the reconstructed glans was completely recovered at 3 months after surgery. The glans skin was pale red and soft, nearly normal at 12 months, with no obvious graft contracture or scar formation. All the patients achieved normal erection and their partners were satisfied with their intercourse. No recurrence or metastasis was observed.

CONCLUSIONThe strategy of partial penis resection, inner thigh skin graft and glans reconstruction, simple, effective, and with few complications, is one of the best treatments of early-stage penile cancer, which not only ensures radical removal of the tumor but also maximally reserves the function of the organ.

OBJECTIVETo explore the prognostic impact of bone marrow involvement (BMI) and therapy in diffuse large B cell lymphoma (DLBCL).

METHODSThe clinical characteristics and prognosis of 83 DLBCL patients with or without BMI were retrospectively analyzed. The treatment outcome of standard CHOP regimen (CHOP group), intensive-dose regimen (intensive-dose group) and rituximab combined therapy (rituximab group) were compared.

RESULTSThe adverse prognostic factors including LDH elevation, ECOG score > or =2, higher IPI and aaIPI score, B symptom, hepatomegaly, splenomegaly, hemoglobin <110 g/L, platelet <100 x 10(9)/L and serum albumin <35 g/L were more prevalent in DLBCL patients with BMI than in those without BMI. Multivariate analysis showed that BMI was an independent prognostic factor of DLBCL. The 3-year OS and PFS rates in rituximab group were 78.1% and 64.3%, respectively, being statistically higher than that in CHOP group (23.6% and 21.8% respectively, P = 0.000 for both) and in intensive-dose group (33.3% and 25.7% respectively, P = 0.002 and 0.001, respectively). But no difference between the latter two groups (P = 0.411 and 0.694, respectively). For the patients with BMI, the 3-years OS and PFS in rituximab group (57.1% and 57.1%) were statistically higher than that in CHOP group (13.9% and 14.1%) and intensive-dose group (29.5% and 16.8%) (P = 0.029 and 0.012 respectively), respectively and also no difference in the latter two groups (P = 0.226 and 0.376 respectively). In the rituximab group, the 3-years OS and PFS were 86.7% and 67.3% respectively in patients without BMI, being higher than that in patients with BMI (57.1% and 57.1%), but the difference was not statistically significant (P = 0.645 and 0.965 respectively).

CONCLUSIONBMI is a negative independent prognostic factors of DLBCL patients. The rituximab combined chemotherapy can significantly improve the therapeutic effect of the DLBCL, and relieve the negative impact of BMI.
