OBJECTIVETo compare the efficacy on vertebrobasilar insufficiency (VBI) between auricular acupuncture therapy and oral administration of medicine.

METHODSSixty patients of VBI were randomized into an auricular acupuncture therapy group and a medicine group, 30 cases in each one. In the auricular acupuncture group, acupuncture was applied bilaterally to gan (CO12) and jiejie (HX8) on the ears and needles were retained for 15 min. After needle withdrawal, the vaccariae semen were fixed with plaster at naogan (AT3, 4i), zhen (AT3), jing (AH12), shen (CO10) and pi (CO13) on the ears. In the medicine group, flunarizine hydrochloride capsules (Sibelium), 5mg were prescribed for oral administration, once every night. The treatment lasted continuously for 2 weeks (14 days) in the two groups. In 2 weeks, the clinical efficacy was assessed and the transcranial doppler (TCD) examination was performed.

RESULTSAfter treatment, the symptom scores were all apparently reduced in the patients of the two groups (P < 0.01, P < 0.05). Compared with the medicine group, the reduced score was much more obvious in the auricular acupuncture group (P < 0.05), indicating the significant difference. After treatment, with TCD examination, the blood velocity was increased to different degrees in the patients of low velocity type in the auricular acupuncture group and the medicine group; that was reduced to different degrees in the patients of high velocity type in the auricular acupuncture group and the medicine group. All of them were different significantly as compared with those before treatment (all P < 0.05). But the difference was not significant between the two groups (both P > 0.05). In comparison of clinical efficacy between the two groups, the effective rate was 93.3% (28/30) in the acupuncture group and better than 76.7% (23/30) in the medicine group, indicating the significant difference in comparison (P < 0.05).

CONCLUSIONThe auricular acupuncture therapy achieves the definite efficacy on VBI and the efficacy is better than flunarizine hydrochloride capsules.

Objectives: To evaluate the clinical significance of nuclear matrix protein 22 (NMP 22) in the detection of bladder transitional cell carcinoma (BTCC) and compare with voided urine cytology(VUC). Methods: A total of 69 cases with voided urine samples for NMP 22 and VUC test were included in this study. Thirty of them were BTCC patients(BTCC group) and twenty nine suffered from other urological diseases (nonbladder cancer group, NBC group). Ten were healthy volunteers (control group). Results: The NMP 22 values for BTCC group (67.3 U/ml) were significantly higher than that of NBC group(7.4 U/ml) and control group (4.3 U/ml)( P 0.05). NMP 22 was more sensitive than VUC in low grade BTCC(Ⅰ,Ⅱ)(62.50% vs 12.50%,P 0.05). Conclusions:Urinary NMP 22 is a useful marker for the early diagnosis of BTCC. It is more sensitive than VUC in low stage and grade BTCC.

OBJECTIVETo study the clinical, radiologic and pathologic features of solitary plasmacytoma of spine.

METHODSThe clinical, radiologic and pathologic features, as well as treatment and follow-up data, of 13 solitary plasmacytoma of spine cases were retrieved and analyzed. Immunohistochemical study using EnVision method for LCA, CD19, CD20, CD79a, CD3, CD7, PC, MUM1, CD138, IgG, IgM, kappa, lambda and Ki-67 was carried out.

RESULTSAll the tumours were primarily located in the vertebrae (including 9 cases in thoracic vertebrae and 4 cases in lumbar vertebrae). The male-to-female ratio was 3.3:1. The age of the patients ranged from 42 to 69 years (mean age = 56 years). The commonest symptom was pain in the surrounding regions. The degree of neurologic disturbance mostly depended on the extent of vertebral destruction and structural instability of the spine. Radiologic examination showed mainly osteolytic lesions in vertebrae. Magnetic resonance imaging demonstrated the presence of heterogeneous intensity inside the involved vertebrae (low in T1 weighted and high in T2 weighted images). Histologic examination showed diffuse infiltration by malignant cells. In well-differentiated plasmacytomas, the tumor cells resembled normal plasma cells. In poorly differentiated examples, the cellular morphology mimicked that of the centroblasts. The interstitial stroma was scanty and contained plenty of vessels, sometimes with formation of blood lakes. Amyloid deposition was present in some of the cases. Immunohistochemical study showed that the tumor cells were positive for CD79a and negative for CD20. Light chain restriction was detected in all the 13 cases studied. Plasma cell marker PC was expressed in all cases, while IgG was positive in 5 cases, IgM in 1 case, MUM1 in 10 cases and CD138 in 8 cases. Ki-67 index varied from 10% to 50%. All cases were operated, with adjuvant chemotherapy and radiotherapy given.

CONCLUSIONSCorrelation of clinical, radiologic and pathologic features is important in diagnosis of solitary plasmacytoma of spine. The possibility of multiple myeloma needs to be excluded. Early detection by radiologic examination, local surgical resection, post-operative chemoradiotherapy and long-term follow-up are prudent for successful management of this condition.

OBJECTIVES: The number of metastatic lymph nodes (LNs) and the ratio between the number of metastatic LNs and the total number of retrieved LNs (the LN ratio [LNR]) have been proposed as risk factors for recurrence of papillary thyroid carcinoma (PTC). However, the significance of the number of LNs and the LNR in patients with clinically node negative PTC has not been clearly determined. The purpose of this study is to evaluate their significance. METHODS: We retrospectively analyzed 382 patients with PTC who had undergone total thyroidectomy with prophylactic central neck dissection (CND) between January 2000 and December 2010. We excluded patients with lobectomy, concurrent lateral compartment neck dissection, a follow-up period less than at least 2 years, number of harvested central LNs less than or equal to one, clinically positive LN, distant metastasis, recurrent cancer or other types of malignancy. The correlations between recurrence and various clinicopathologic characteristics including tumor size, extrathyroidal extension (ETE), stage, number of metastatic central LNs, and the LNR were investigated. RESULTS: After a mean follow-up period of 82.2±26.4 months, recurrence occurred in 14 patients (3.7%). Tumor size ≥20 mm, maximal ETE, presence of central LN metastasis, number of metastatic LNs ≥2, and LNR ≥0.31 correlated with recurrence in the univariate analysis. However, tumor size ≥20 mm, maximal ETE, number of metastatic LNs ≥2, and LNR ≥0.31 were significantly associated with recurrence in the multivariate analysis (hazard ratio=6.61, 7.17, 3.43, and 11.23, respectively). CONCLUSION: The LNR and the number of metastatic LNs are independent prognostic risk factors for recurrence in patients with clinically node negative PTC, and these factors can be used to guide postoperative adjuvant therapy and follow-up strategy after prophylactic CND.

OBJECTIVETo investigate the prognosis of adenoid cystic carcinoma (ACC) in minor salivary glands and its influencing factors.

METHODSClinical data of 52 patients with ACC in minor salivary glands were reviewed. The distribution of stage was as follows: stage I (6%), stage II (21%), stage III (27%) and stage IV (46%). Counting data was analyzed by χ(2) test or Fisher's exact. Survival rates were calculated by Kaplan-Merier method. Statistical significance of differences in the cumulative survival curves was evaluated using the Log-rank test. Multivariate analysis was performed by Cox proportional hazard model.

RESULTSAll patients underwent primary tumor radical resection, 39 patients (75%) received postoperative radiation. The regional recurrence rate was 37% and distant metastasis rate was 21%. The 5-, 10-year cumulative local control rate were 68% and 63% respectively. The 5-, 10-year cumulative distant control rate were 86%, 68% respectively. The 5-, 10-year tumor specific survival rates were 70% and 54% respectively. Multivariate analysis showed that T stage, lymph node metastasis and perineural invasion were relevant to the tumor specific survival of ACC in minor salivary glands.

CONCLUSIONSRecurrence and metastasis were the main cause of treatment failure of ACC in minor salivary glands. T stage, lymph node metastasis and perineural invasion were the independent prognostic factors of ACC in minor salivary glands. Radical surgery and reasonably postoperative radiotherapy were the main treatment strategy.

OBJECTIVETo evaluate the efficacy of surgery for the patients with pyriform sinus carcinoma and analyze the prognostic factors related to the cancer.

METHODSBetween December 1995 and December 2002, 62 patients with pyriform sinus cancer were treated in Zhejiang Tumor Hospital. There were 13 patients staged T1, 17 T2, 12 T3, 20 T4. Four patients received preoperative radiation and 40 patients had post-operative radiation. Among 62 patients, 33 patients were treated by partial laryngectomy, 29 patients were treated by total laryngectomy.

RESULTSThe survival rate was calculated with Kaplan-Meier method. The overall 3- and 5-year survival rates were 42.3% and 27.8%, respectively. The 3-year survival rate between partial and total laryngectomy was 51.9% and 29.9%. The 5-year survival rate between partial and total laryngectomy was 39.5% and 11.2% (chi2 = 4.14, P<0.05). Early stage and combined modality therapy were the independent favorable prognostic factors.

CONCLUSIONSEarly diagnosis with treatment and combined treatment are the most important factors influencing the survival of patients with pyriform sinus carcinoma. Partial laryngopharyngectomy is a suitable treatment for early and selected advanced pyriform sinus carcinoma with a good function and oncologic outcome.
