Objective To investigate the monitoring of the recurrent laryngeal nerve (RLN)function during thyroid surgery by recording the compound muscle action potential (CMAP) of lateral cricoarytenoid muscle(LCA) under block anaesthesia of the cervical plexus. Methods Nicolet Endeavor CR(Viasys Healthcare, USA) was applied for the intraoperative monitoring. A pair of needle electrodes were inserted into LCA to record CMAP, and a concentric electrode was used to intermittently stimulate the RLN for monitoring the RLN function during operation under block anaesthesia of the cervical plexus.Results In these 28 cases 31 RLNs were exposed during operation, CMAPs appeared with consistent latency when stimulation was applied at the exposed segment. The stimulating intensity threshold ranged from 0.2 to 1.6 mA. The average value was 0.96 mA. 25 of 31 showed CMAPs with consistent latency when stimulation was provided along the possible pathway of the unexposed segment. The stimulating intensity threshold ranged from 1.3 to 3.5 mA. The average value was 2. 03 mA. 6 of 31 did not evoked CMAP even though the maximal stimulating intensity was 5 mA. When these six nerves were exposured, compound muscle action potential were evoked consistently. All of the 28 patients had normal phonation function after surgery.Conclusions It is a safe, effective and feasible method to monitor the RL N function by recording the CMAP of lateral cricoarytenoid muscle under block anaesthesia of the cervical plexus.

Objective To discuss the diagnosis and treatment of splenic harmatoma(SH). Methods The clincial data of three cases of SH treated in our hospital from January 1997 to December 2007 were collected,and the other 17 cases which were published from January 1997 to December 2007 in the Chinese biological and medical lit-erature database were reviewed. The clinical manifestation,pathological findings,diagnosis and treatment of these 20 patients were analyzed. Results The main symptoms were abdominal pain or discomfort and abdominal mass in 13 cases(13/20). All 20 patients underwent surgical treatment with good recovery without severe complications and re-currence. Conclusions The definite diagnosis of SH depends on postoperative pathological findings. Complete surgi-cal resection is the best treatment for SH with favourable prognosis.

OBJECTIVETo explore mechanism of acupuncture for renal interstitial fibrosis (RIF) in hypertension rats.
METHODSTwenty-four 24-week-old male spontaneously hypertensive rats were randomly divided into a model group, a perindopril group and an acupuncture group, eight cases in each one. In the acupuncture group, with rats tied up, electroacupuncture was applied at bilateral "Quchi" (LI 11) and "Zusanli" (ST 36) under mild vibration of needle handle for 20 min, once a day. In the perindopril group, perindopril (0.4 mg/kg) suspension liquid was applied for intragastric administration, once a day. In the model group, rats were tied up for 20 min a day without any treatment. Eight same-age same-race Wistar Kyoto (WKY) rats with normal blood pressure were taken as a control group, which was given with free diet but no treatment. The treatment was reuqired for six weeks. The systolic blood pressure of caudal artery was tested. Kidney morphological structure was observed by HE coloration. Deposition optical density of type I and III collagen in kidney was tested by immunohistochemistry. Expression of transforming growth factor-beta1 (TGF-beta1) mRNA was tested by reverse transcription polymerase chain reaction (RT-PCR) method.
RESULTSCompared with the model group, the blood pressure was significantly decreased in the acupuncture group (P < 0.01), the damage of kidney morphology was minor, positive depositional area of type I and III collagen was obviously decreased (both P < 0.05), and the expression of semi-quantitative analysis of TGF-beta1 mRNA was decreased (P < 0.05), which had similar effect as western medication perindopril.
CONCLUSIONAcupuncture at "Quchi" (LI 11) and "Zusanli" (ST 36) probably intervenes the process of RIF by reducing synthesis of kidney type I , III collagen and restraining expression of TGF-beta1.

Objective To evaluate whether 18F-fluorothymidine(FLT) can be used to monitor early response to irradiation in colorectal cancer (CRC).Methods SW480 cells were cultured and irradiated with 0, 10, and 20 Gy.Twenty-four hours later, morphological changes, apoptosis, necrosis, proliferation,and cell cycle phases were observed.Uptake of 18F-FLT was measured in these tumors in vitro from 24 h to 72 h after irradiation.The one-way analysis of variance was used to analyze the data.Results Apoptotic and necrotic cells were detected 24 h after radiotherapy.SW480 cells proliferation was significantly delayed after irradiation in 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenylte-trazolium bromide (MTI) assay.Cell cycle analysis showed that SW480 cells had a decreased fraction of cells in S phase( from 33.23% to 9.24%,then to 5.43% ) and an arrested fraction in G0-G1.After SW480 cells were cultured for60 min, the uptake of 18F-FLT was (5.21 ± 1.60) %; and 24 h after irradiation of 10 Gy, the uptake decreased significantly to (4.27±0.48)% (F=8.253, P=0.009).And 72 h after irradiation, the uptake further decreased significantly to (3.39 ± 0.59) % ( F = 36.715, P<0.001 ).In tumor tissue, the uptake of 18F-FLT reduced significantly 72 h after radiotherapy (10 Gy:F = 12.388, P = 0.007; 20 Gy:F = 16.744, P = 0.004) and the attenuation degree increased with the radiation dose.Conclusion The uptake of 18F-FLT in SW480 cells or in CRC could reflect the changes of SW480 cells in proliferation, cell cycle re-distribution, cell apoptosis and necrosis.The results suggest that 18F-FLT may be used for monitoring early response to irradiation of CRC.

Objective To evaluate the predictive value of 18F-fluorodeoxyglucose (FDG) and 18F-fluorothymidine(FLT) PET in monitoring the metastatic potential of human colorectal cancer (CRC).Methods Human CRC cell lines SW480 and SW620 were cultured and implanted into nude mice to create CRC models. Tumor growth,metastatic status and survival were assessed in CRC bearing mice. Uptake of 18F-FDG and 18F-FLT in SW480 and SW620 cells was detected In vitro at 0,30,60,90,120 min after incubation. PET images of both tracers were acquired for SW480 and SW620 tumor-bearing mice using the small animal PET at 60 min after tracer injection. Region of interest (ROI) was drawn using Image J software on reconstructed PET images. Immunocytochemistry and Western blot analysis of the tumor tissue were performed. The correlation between tracer uptake and tumor marker expression was evaluated using linear regression. Results Compared with SW620 tumor-bearing mice,SW480 induced tumor grew much faster ( t = - 3.332,P = 0.004),the tumor-bearing mice had more serious dyscrasia ( t = 2.240,P = 0.038 ),shorter survival and higher metastatic rate. In vitro study,the uptake of both 18F-FDG and 18F-FLT in SW620 cells was lower than that in SW480 cells. 18F-FLT uptake was higher than 18F-FDG uptake in both SW480 and SW620 cells. After incubation for 60 min,the uptake of 18F-FDG in SW480 and SW620 cells was ( 1.76 ± 0.87 )% and ( 1.14 ± 0.38 )%,respectively ( t = - 2.507,P = 0.021 ); while the uptake of 18F-FLT in SW480 and SW620 cells was (5.21 ± 1.60)% and (2.90 ± 1.82)%,respectively (t =3.497,P =0.002). In micro-PET study,the 18F-FDG radioactivity ratio of tumor to non-tumor (T/NT) in SW480 and SW620 tumors was 2.69 ± 0.98 and 3.09 ± 1.26 respectively (t =0.657,P =0.524); while T/NT of 18F-FLT in SW480 and SW620 tumors was 3.65 ±0.51 and 2.22 ±0.42 (t =6.491,P <0.001 ),respectively. In immunocytochemistry and western blot assay,heat shock protein(HSP) 27,Integrin β3,vascular endothelial growth factor receptor 2 ( VEGFR2 ) and Ki67 were all over expressed in two kinds of tumor cells with different intensities. HSP27 and Integrin β3 expression was higher in SW480 cells than that in SW620 cells. While VEGFR and Ki67 expression was lower in SW480 cells than that in SW620 cells. The uptake of 18F-FLT closely correlated with the expression of HSP27 ( r =0.924,P =0.004) and Integrin β3 (r=0.813,P =0.025). 18F-FDG uptake inversely correlated with the survival of tumor-bearing mice (r =0.500,P=0.017). Conclusions The uptake of 18F-FDGand 18F-FLT may reflect different biological characteritics of CRC. High 18F-FLT uptake in CRC on PET scan may predict high metastatic tendency.
