OBJECTIVE To study the clinical value of superficial layer coagulation of trigeminal sensory root in the treatment of trigeminal neuralgia. METHODS The clinical data of 5 cases with trigeminal neuralgia were studied. Head MRI (B-FFE) examinations were made before surgery and operations were performed via retrosigmoidal approach. One case with left facial pain showed 3 arteries with offsets crossing and compressing the left trigeminal nerve. Among 4 cases with right facial pain,3 cases had an artery compressing the right trigeminal and the nerve were distorted and moved from its original site,one case with an artery going with trigeminal nerve sensory root branchlets. All cases were no indications for microvascular decompression and thus were treated with surface coagulation of trigeminal nerve sensory root. RESULTS Pain disappeared instantly after operation and facial sensory were retained. All cases were followed up for 2.4 to 5 years and no recurrences were found. CONCLUSION Superficial layer coagulation of trigeminal sensory root is a safe and effective method for the treatment of trigeminal neuralgia.

Objective To study the simple preparation method and structure of nano-hydroxyapatite/collagen composite, to investigate new substitute of repairing bone for using in tissue engineering. Methods Porous nano-hydroxyapatite was made of Ca (OH)2 and H3PO4. Collagen was drawn from fresh adult bovine tendon. The two materials were prepared into biomembrane through the glutaraldehyde and freeze-drying. The crystallite phase, micro-morphology, structure, crystallite size of the composite were examined by XRD and scanning electronic microscop (SEM). Results The results showed that the composite structure was porous and consisted of nano-hydroxyapatite (10 nm ? 50 nm - 20 nm ? 80 nm) and collagen fiber. The crystallite phases and size of the composite was similar to that of natural bone. Conclusion The porous nano-hydroxyapatite /collagen composite is expected to be an ideal substitute of repairing bone.

Objective To detect the levels of plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) and investigate its relationship with liver function, ascites and heart structure in patients with liver cirrhosis. Methods The levels of plasma NT-proBNP and various clinical and biochemical parameters were determined in 60 patients with liver cirrhosis and 30 healthy controls. Meanwhile Child-Pugh liver function was classified. All people underwent color Doppler echocardiography. Results The level of plasma NT-proBNP was significantly elevated in patients with liver cirrhosis [(38.63±36.05)pmol/L], compared with that of the controls [(7.50±8.25)pmol/L],P<0.01. There was no significant difference in different Child-Pugh class and aseites amount of liver cirrhosis. E/A < 1 and E wave decelerate time (EDT) was in-creased in liver cirrhosis. Conclusion The levels of plasma NT-proBNP in liver cirrhosis are significantly elevated, and related to early impairment of diastolic function. But it does not correlate with liver function and aseites.

Aim To study and compare the pharmaco-kinetic parameters of roxithromycin under normoxic and hypoxic rats. Methods A highly effective and rapid ultra-performance liquid chromatography with tandem mass spectrometry ( UPLC-MS/MS) method with posi-tive electrospray ionization source was successfully de-veloped and validated for quantification of roxithromy-cin in rat plasma. Sprague-Dawley rats were randomly divided into the hypoxia and normoxic groups. Each rat obtained a single dose of roxithromycin with 10 mg · kg-1 via intragastric administration. The pharmacoki-netic parameter comparison between normoxic and hy-poxic groups was calculated by SPSS software using in-dependent sample t test method. Results The main pharmacokinetic parameters of roxithromycin between the normoxic and hypoxic rats were:the AUC(0-t) 7 576 and 3 761 μg·h·L-1 , MRT(0-t) 5. 6 and 7. 7 h, T1/2 3. 4 h and 3. 9 h, CL 1. 5 and 3. 0 L · h-1 · kg-2 , tmax3. 1 and 3. 4 h, Cmax 1 116 and 372 μg·L-1 , re-spectively. The levels of Cmax and AUC of roxithromy-cin in hypoxic rats were statistically lower than those in normoxic rats. Conclusion The exposure level of rox-ithromycin in hypoxic rats markedly decreased. Our re-sults may provide an important experimental basis to adjust the dosage for roxithromycin in hypoxic clinical practice.

Objective To explore the feasibility of imaging and treatment of cervical cancer xenograft model using 131I mediated by hNIS gene transfection. Methods The cervical cancer xenograft models were established with Hela-NIS( +) cells and Hela cells, respectively. Five Hela-NIS( +) xenograft models and five Hela xenograft models were dynamically imaged at 0.5, 1, 2, 4, 8, 16 and 20 h postinjection of 131I(7.4 MBq). Five Hela-NIS( +) xenograft models were imaged at 0. 5,1,2,4,8,16, 20 and 25 h postinjection of 99TcmO4-(11.1 MBq). Twenty Hela-NIS( +) cervical cancer xenograft models were randomly divided into four groups: Three 131I treating groups and one control group. The therapeutic effects of 131I at threelevels (74,111,148 MBq) were investigated following intraperitoneal injection. Results Hela-NIS( +)human cervical cancer xenografts were established successfully in nude mice. The Hela-NIS( +) xenografts significantly accumulated radioactivity after intraperitoneal injection of 131I, and the radioactivity was persistently present until 20 h postinjection, but Hela xenografts had no radioactive accumulation. The T/B value of the Hela-NIS( +) xenografts reached 17.34 at 8 h postinjection. The imaging with 99TcmO4- showed that the radioactivity was persistently present in Hela-NIS( +) xenografts for almost 25 h. The Hela-NIS( +)xenografts shrinked after 131I treatment. The inhibition ratios of tumor growth in 111 MBq and 148 MBq groups were both significantly higher than that of 74 MBq group (t: 2.74-5.75, P ＜0.05). Conclusions Hela-NIS( +) cervical cancer xenografts in nude mice could persistently accumulate 131I and 99TcmO4- and could be treated successfully with 131 I. 131 I treatment mediated by hNIS gene transfection could be a promising cancer treatment method.

Adiponectin levels in cirrhosis was correlated positively with insulin and negatively with insulin sensitively index,and did not correlate with TNF-? and liver function.Conclusion Serum adiponectin levels in cirrhosis are significantly elevated. Adiponectin levels do not correlate with TNF-? and liver function, but exclusively insulin and insulin sensitivity index.

Objective:To study the occlusion characteristics of the young subjects with bruxism before and after treatment by elastic occlusal splint. Methods:10 patients with bruxism and aged 22-27 years(n=10) were treated by elastic occlusal splint, before and 6 months after treatment they were examined by T-Scan occlusion detector. The occlusion time( OT) , disclusion time( DT) , oc-clusion force( OF) , the perentage of occlusion force( POF) , the changes of the position of center occlusal force( COF) and the asym-metry index of occlusion force(AOF) were observed and compared with those of the healthy controls(n=10). Results: ① In the case group there was significant difference in the OT and DT between left and right anterior teeth before treatment (P<0. 05), but not after treatment (P>0. 05). There was significant difference in the momevent of COF of left and right side, the POF of right side and the AOF between the 2 groups before treatment, but not after the treatment(P>0. 05). ② In the case group after treatment the OT and DT of left and right anterior teeth were shortened(P<0. 05). The POF of right side and the AOF were significantly improved. In the case group DT, OF center excursion, the left POF and the AOF showed no significant difference before and after treatment( P>0. 05). Conclusion:The occlusal factors such as early contact, lateral teeth synthetic interference, occlusal force center excursion have close relationship with bruxism. Elastic occlusal splint can effectively correct muscle dysfunction and make occlusal relationship more coordinated and stable, and therefore is effective in the treatment of bruxism.
