Objective:To analyze the metastasis rule of abdominal lymph node from thoracic esophagus carcinoma. Methods:The abdominal lymph node data on 164 patients who had undergone resection of thoracic esophageal carcinoma were analyzed retro-spectively. Grouping was based on the upper, middle, and lower thoracic esophagus. Differences in tumor infiltration depth, differentiat-ed degree, pathological type, pathological stage, and metastasis rate of the abdominal lymph node among the three groups were com-pared. The metastasis rates of the abdominal lymph nodes among the different tumor infiltration depths, differentiated degrees, and path-ological types were also compared. Results:The base condition of tumor infiltration depth, differentiated degree, pathological type, and pathological stage has no statistical significance among the upper, middle, and lower thoracic esophagus. The metastasis rate of the ab-dominal lymph node also has no statistical significance among the three groups (upper, 6.9%;middle, 27.4%;and lower, 39.6%). More-over, the metastasis rate of the abdominal lymph node has no statistical significance among the different tumor infiltration depths, differ-entiated degrees, and pathological types. Conclusion:A special bound lymph node metastasis was present in the esophageal carcinoma. If the tumor in the upper thoracic esophagus infiltrated the submucosa, then it could bound metastasize down to the abdominal lymph node by the lymphatic capillary net. The majority of the esophageal carcinoma was more than T1b period when diagnosed. The tumor has infiltrated the submucosa. Thus, early stage, well-differentiated, and upper thoracic esophageal carcinoma does not indicate mini-mal metastasis of the abdominal lymph node. Routine abdominal lymph node dissection through radical surgery for esophageal carcino-ma was necessary.

OBJECTIVETo investigate clinical effects of arthroscopy in the treatment of medial meniscal cyst.
METHODSFrom June 2011 to January 2013, 7 patients with medial meniscal cyst were treated with arthroscopy. There were 3 males and 4 females,ranging in age from 27 to 63 years old,with a mean age of (43.93±2.10) years old. The cysts have been discovered for 3 to 30 months,with a mean time of (10.6±1.3) months. All the patients complained of knee pain,especially in the medial joint gap. The Pisani sign, Caklin sign and medial McMurray sign were all positive. Preoperative MRI examination confirmed the diagnosis. Lysholm score changes and clinical efficacy were observed through a six-month follow-up.
RESULTSThe postoperative Lysholm scores were all significantly higher than the preoperative scores. According to Sarimo standard, 6 patients got an excellent result, and 1 good.
CONCLUSIONArthroscopic treatment of medial meniscal cyst has replaced the traditional method, which could retain the normal meniscus as much as possible and repair the meniscus injury simultaneously, as well as get a good curative effect and a good recovery of knee function. This method is worthy of clinical application.

Objective To study the feasibility and effectiveness of liquid embolic agent HEMA-MMA in the arterial embolization therapy for the rabbit renal VX2 tumor models. Methods Renal VX2 tumor models were inoculated with the method of percutaneous CT-guided implantation of a small fragment of tumor into the inferior pole of the right kidney and were embolized when the max diameter was 1.5 cm. One model was embolized with the mixture of HEMA-MMA and carbonyl iron powder and was harvested immediately after embolization, the sample was fixed by paraformaldehyde for histopathological examination with methylene blue staining and HE staining to demonstrate the sizes of the vessels that the HEMA-MMA could reach. The remaining models were treated with pure HEMA-MMA by superselective or nonselective embolization (SSE or NSE). In SSE group, only the renal artery branch supplying the tumor was superselectively catheterized and embolized until the presence of“artery casting”change. In NSE group, the microcatheter was catheterized into the main renal artery then the whole renal artery branches and the renal capsular artery were embolized simultaneously until the presence of“artery casting”shape. Non-enhanced CT scans at immediate postoperation, on postoperative day 1 and day 3 were performed. The enhanced CT scans at the postoperative 1, 2 , 4 and 6 weeks were performed. Necrotic zone of the tumor was defined as non-enhancement in parenchyma phase, residual tumor was defined as delayed enhancement around the necrotic zone or obvious thickness and enhancement of the adjacent renal capsule. When detecting residual tumor, the model was followed up another 1 week and then harvested for histopathological examination. If there was no residual tumor and lung metastasis in 6 weeks follow-up after operation, we defined this as complete necrosis and then harvested the kidney for histopathological examination. Results Eleven of the 12 rabbits were successfully inoculated VX2 tumors. The mixture of HEMA-MMA and carbonyl iron powder deposited in the arterial vessels demonstrated mazarine in methylene blue staining and brownness in HE staining. The diameter of the tumor vessels which the agent could reach was 30—150 μm, there was no embolic agent detected in the venous blood vessels. 5 models were performed with superselective embolization and the other 5 were embolized with nonselective embolization. The embolic agent demonstrated high density and obviously deposited in the surrounding zone of the tumor on immediate postoperative CT images, density of the surrounding zone decreased accompanied by density increase in the central area of the tumor on the first day postoperative CT images. Density difference between the embolism zone and normal renal tissue disappeared on the third day postoperative CT images accompanied by swelling changes of the embolized area. Residual tumor was detected in all 5 superselectively treated cases (2 in 1 week, 3 in 2 weeks), which located in the area of junctional zone and subrenal capsule. The necrotic zone was demonstrated coagulative necrosis on histopathologic images, the boundary between the residual tumor and the necrotic zone was clearly showed both on histopathologic images and gross specimen. Renal capsular artery participating in the residual tumor blood supply was also shown on gross specimen. There was no residual tumor and lung metastasis detected in nonselective treated group during the period of 6 weeks follow-up. Atrophy of the whole tumor-burdened kidney was shown on gross specimen and complete coagulative necrosis of the total tumor and the renal capsule adjacent to the tumor was demonstrated on histopathologic images. Conclusions Liquid embolic agent HEMA-MMA can embolize tumor blood vessels with a diameter of 30—150 μm. The renal capsular artery participates in the blood supply of the VX2 kidney tumor, so only superselective embolization of the renal artery branch with this liquid embolic agent may not induce the whole necrosis of the tumor, but complete necrosis of the tumor can be obtained by embolizing of all the tumor vessels and the adjacent normal renal arteries with this liquid embolic agent.

BACKGROUND: Studies showed that both anterior cervical disc replacement and anterior cervical decompression and fusion can achieve good clinical result in cervical spondylosis. However, it is not conclusive about which kind of surgical method has an advantage in avoiding the adjacent segment degeneration. OBJECTIVE: To compare the effect on adjacent segment degeneration of single segment cervical disc herniation treated with anterior cervical decompression and fusion and anterior cervical disc replacement. METHODS: We col ected clinical data of 178 patients with cervical disc herniation and receiving anterior cervical disc replacement or anterior cervical decompression and fusion from January 2009 to December 2012. A retrospective analysis was performed. There were 116 cases in the anterior cervical decompression and fusion group and 62 cases in the anterior cervical disc replacement group. RESULTS AND CONCLUSION: (1) Evaluation: visual analogue scale score, Japanese Orthopaedic Association Scores and neck disability index were improved significantly in both groups during final fol ow-up compared with that pre-treatment (P < 0.05). (2) No significant difference in range of motion of operation segment, adjacent upper segment and adjacent lower segment was detected between final fol ow-up and pre-operation in the anterior cervical disc replacement group (P > 0.05). At 3 months after surgery, in the anterior cervical decompression and fusion group, surgical segment was confluent, and range of motion lost. During final fol ow-up, range of motion of adjacent upper segment and adjacent lower segment was significantly increased, and the increased range of motion in the upper segment was bigger than that of the lower segment (P < 0.05). (3) During final fol ow-up, X-ray films and MRI images revealed the number of degenerated adjacent segment was more in the anterior cervical decompression and fusion group than in the anterior cervical disc replacement group (P <0.05). The number of degenerated middle and upper segments was more than that of the lower segment in both groups (P < 0.05). (4) The findings confirmed that anterior cervical disc replacement or anterior cervical decompression and fusion for treating cervical disc herniation could effectively relieve nerve symptoms of patients. However, compared with the anterior cervical disc replacement, adjacent segment degeneration occurs more commonly after anterior cervical decompression and fusion.
