Cancer Research and Clinic 2011;23(5):328-330
Objective To analysis the clinical characteristics, treatment and prognosis for patients with cervical cancer with lymph lode of paraaortic and /or supraclavicular metastasis after combined treatment in two years. Methods Data of 20 patients with lymph lode of paraaortic and /or supraclavicular metastasis of cervical cancer were analyzed retrospectively. Results There was no evidence of lymph node of paraaortic and supraclavicular metastasis before the first combined treatments according to the MRI/CT/SPECT scans in these 20 patients. However, lymph lode of paraaortic and/or supraclavicular metastasis were seen in two years after treatments, the shortest is two months. One patient was progressing during treatment whose pathologic diagnosis is mucinous adenocarcinoma, died in 6 months from treatment start. There was only paraaortic metastasis in 15 patients, among these, 4 patients were found lymph lode of left supraclavical metastasis after retreatments in 3-6 months. Both paraaortic and left-supraclavical lymph node metastasis in 4 cases. Among these 20 cases, recurrence and to give up treatment, whose median survival time is 7.50 months, recurrence and to gain treatment, whose median survival time is 18.98 months, there was significant difference (x2=7.23, P<0.01). Conclusion Patients with cervical cancer with lymph lode of paraaortic and/or supraclavicular metastasis after combined treatment will obviously extend survival time after retretments, which has positive therapy significance.

Objective To systematically assess the efficacy and safety of electroacupuncture for trigeminal neuralgia. Method Randomized controlled trials of a electroacupuncture treatment for trigeminal neuralgia were sought by a computer search of CNKI,Wan Fang Data,VIP,CBM,PubMed,EMbas and The Cochrane Library.The retrieval time limit was from March 1996 to March 2016. Two reviewers sifted the literature and extracted data independently according to the inclusion and exclusion criteria andthen assessed the riskofbias of the included literatureusing the Cochrane risk of bias assessment tool.Ameta-analysis was made using RevMan 5.3.Result Finally, 12 articles were included with atotal of 847 subjects.The results ofmeta-analysis showed that the total efficacy rate was higher in the electroacupuncture group than in the control group [OR=4.04,95%CI(2.67, 6.13),P<0.00001].There were no statistically significant differences in the VAS score [MD=﹣0.06,95%CI(﹣0.59, 0.47),P=0.82] and the recurrence rate [OR=0.64,95%CI(0.05,7.45),P=0.54] between the electroacupuncture and control groups.Conclusion The currentlimited evidenceshows that the total efficacy rate fortrigeminal neuralgiais higher in the electroacupuncture group than in the control group.There are no statistically significant differences in the VAS score and the recurrence rate of trigeminal neuralgia between the electroacupuncture and control groups of patients.But the conclusions need more high-qualitytrials for validation owing to the limitation of the sample size of the included studies.

BACKGROUND:Currently, fibroblast-like synoviocytes from the synovial tissue of patients with rheumatoid arthritis or adjuvant arthritis rats are isolated and cultured mainly using enzyme digestion method, but tissue explant adherent method is rarely reported in primary culture. OBJECTIVE:To establish a culture method of fibroblast-like synoviocytes from adjuvant arthritis rabbits and to investigate cell biological characteristics. METHODS:Rabbit models of adjuvant arthritis were prepared by injected with adjuvant at multiple sites and times, the knee synovial tissues were obtained, and fibroblast-like synoviocytes were separated and cultured by the tissue explant adherent method. Furthermore, the cell morphology was observed. The cell proliferation was measured using cell counting kit-8 assay, and the expression of Vimentin was detected by immunofluorescence.RESULTS AND CONCLUSION:The primary cultured rabbit synoviocytes were long spindle fiber-like and coincided with the fibroblast-like synoviocytes. Moreover, cells were positive for Vimentin. In conclusion, fibroblast-like synoviocytes from rabbits with adjuvant arthritis are successfully isolated and cultured by the tissue explant method.

OBJECTIVEThis work lays the foundation for establishing a digital model database with normal occlusion. A digital dental cast is acquired through grating projection, and model features are measured through reverse engineering.
METHODSThe grating projection system controlled by a computer was projected onto the surface of a normal dental model. Three-dimensional contour data were obtained through multi-angle shooting. A three-dimensional model was constructed, and the model features were analyzed by using reverse engineering. The digital model was compared with the plaster model to determine the accuracy of the measurement system.
RESULTSThe structure of three-dimensional reconstruction model was clear. The digital models of two measurements exhibited no significant difference (P > 0.05). When digital and plaster models were measured, we found that the crown length and arch width were not statistically different (P > 0.05), whereas the difference between the crown width and arch length was statistically significant (P < 0.05).
CONCLUSIONThe reconstruction of a digital model by using the grating projection technique and reverse engineering can be used for dental model measurement in clinic al and scientific research and can provide a scientific method for establishing a digital model database with normal occlusion.

OBJECTIVETo investigate the expressions of sphingosine-1-phosphate receptors 1-3 (S1P1- 3) in the corpus cavernosum of castrated male rats and its relationship with the NOS/NO/cGMP and RhoA/Rho kinase signaling pathways.
METHODSWe equally randomized 18 eight-week-old healthy male SD rats into a sham-operation control, a castration, and a testosterone replacement (TR) group and harvested the bilateral testes and epididymides from the rats in the latter two groups, followed by 4 weeks of subcutaneous injection of testosterone propionate at 3 mg per kilogram of the body weight per day for those in the TR group and that of plant oil for those in the control and castration groups. At the age of 12 weeks, we measured the serum testosterone (T) level and maximum intracavernous pressure/mean arterial pressure (ICPmax/MAP) of the animals and determined the expressions of SlP1-3, eNOS, P-eNOS, ROCK1, and ROCK2 in the corpus cavernosum by Western blot and immunohistochemistry.
RESULTSThe serum T level was significantly decreased in the rats of the castration group as compared with those of the control and TR groups ([0.41 ± 0.04] vs [16.01 ± 1.02] and [15.84 ± 1.32] nmol/L, P < 0.01), with no statistically significant difference between the latter two groups. The ICPmax/MAP at 0 V, 3 V, and 5 V electric stimulation was remarkably lower in the rats of the castration group (0.088 ± 0.014, 0.323 ± 0.014, and 0.432 ± 0.012) than in those of the control group (0.155 ± 0.011, 0.711 ± 0. 010, and 0.819 ± 0.024) and TR group (0.153 ± 0.012, 0.696 ± 0.017, and 0.763 ± 0.027) (P < 0.01), with no significant difference between the latter two groups. With GAPDH as internal control, the animals of the castration group showed markedly reduced expressions of S1P1 ([49.99 ± 3.39]%), eNOS ([46.82 ± 3.81]%) , and P-eNOS ([45.42 ± 4.35]%) in comparison with those in the control group ([72.57 ± 3.06], [89.76 ± 3.98], and [82.53 ± 8.92] and TR group ([71.77 ± 4.43], [87.19 ± 4.23], and [79.82 ± 7.38]%) (P < 0.01) , while the expressions of S1P2, S1P3, ROCK1, and ROCK2 were significantly upregulated in the castration group ([82.35 ± 4.13], [61.03 ± 5.14], [74.50 ± 4.02], and [69.83 ± 5.75]%) as compared with those in the control group ([41.67 ± 1.68], [31.66 ± 2.67], [35.69 ± 5.56], and [39.85 ± 7.17]%) and TR group ([42.80 ± 3.87], [32.25 ± 4.22], 38.06 ± 5.21], and [42.36 ± 4.44]%) (P < 0.01).
CONCLUSIONAndrogen deficiency induces significant reduction of ICPmax/ MAP in male rats, which is possibly associated with the decline of S1P1 in the corpus cavernosum, inhibition of the eNOS/NO/cGMP signaling pathway, increased expressions of S1P2 and S1P3, and activation of the RhoA/Rho kinase signaling pathway.
