2.Clinical analysis of paraaortic combined with or not supraclavicular lymph node metastasis in patients with cervical cancer after combined treatment
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 study the protective effects of ?-asarone on PC12 cells damage induced by Glutamate. Method The effects of ?-asarone on PC12 cells after Glutamate intoxication on morphology, extent of damage, livability, intracellular calcium concentration and apoptosis ratio were observed. Result Morphological changes, LDH leakage and intracellular calcium concentration increasing, and cell survival decreasing were observed in PC12 cells exposured to Glutamate. 7.5, 15, 30 ?g/mL?-asarone can increase cell survival, decrease LDH leakage. 15, 30 ?g/mL ?-asarone can reduce intracellular calcium concentration and apoptosis ratio. Conclusion ?-asarone prevents the toxicity of Glutamate, and it maybe attribute to its effect of anticalcium.

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.

Objective:To isolate rabbit fibroblast-like synoviocytes(FLSs) by suspended explant culture method. Methods:The healthy rabbit joint synovial layers were obtained. The cells were cultured by suspended explant culture method and compared with the explants adherent culture method. The growth status and morphology were observed. The growth curve of the 3rd passage cells was measured by CCK-8 assay,and the expression of vimentin was tested by immunocytochemistry. Results: The FLS obtained by the two methods exhibited a spindle-shaped appearance and could rapidly expand. The cell growth curve was typical of S type, and the cells highly expressed vimentin. Conclusion:Primary culture of rabbit fibroblast-like synoviocytes by suspended explant culture method were successfully established. The method was simple and highly efficient. It provided a new method for the isolation of FLS in vitro.

OBJECTIVETo investigate the effect of different pressure oxygen pre-breathing in preventing decompression sickness of rats.
METHODSForty male SD rats were randomly divided into 4 groups: decompression sickness (DCS) group and three oxygen pre-breathing groups with 1 ATA, 2 ATA and 3 ATA pressure respectively. The rats of DCS group were placed in the hyperbaric chamber and the chamber was compressed evenly within 3 minutes to depths of 7 absolute atmosphere(ATA) and held at the designated depth for 60 min, then decompressed (3 min) at constant speed to the surface pressure. After that, the rats were taken out for further detection. While the rats of oxygen pretreatment groups pre-breathed different pressure oxygen for 20 min before entering into chamber. The mortality and behavioral of rats were observed with 30 min post decompression. The dry/wet ratio of the lung, protein levels in the bronchoalveolar lavage fluid (BALF), and the inflammatory cytokine tumor necrosis factor (TNF-alpha) expression were also tested.
RESULTSCompared with that of the DCS group, the mortality and morbidity of oxygen pre-breathe groups didn't change obviously. But the total BALF protein level and the inflammatory cytokine TNF-alpha expression of 1 ATA oxygen pre-breathe group were obviously decreased, while the dry/wet ratio of lung as obviously increased instead (P < 0.05).
CONCLUSIONAlthough preoxygenation can' t obviously change the mortality and mobidity of rats, normal pressure oxygen pre-breathing can mitigate the protein infiltration in BALF and the expression of inflammatory cytokine in lung tissue.

Objective To evaluate the CT findings and classification of the Le Fort fracture. Methods Sixty-two cases with Le Fort fractures were studied with thin-slice high-resolution CT scanning and analyzed with three-dimensional(3D)imaging reconstruction.Results Of the 62 patients,10 had Le Fort type Ⅰ fracture,9 had Le Fort type Ⅱ fracture,8 had Le Fort type Ⅲ fracture,and 35 had various combinations of the three types of Le Fort fractures,including 18 Le Fort Ⅰ+Ⅱ fracture,7 Le Fort Ⅰ+ Ⅱ+Ⅲ fracture and 10 Le Fort Ⅱ+Ⅲ fracture.Fifty-five cases had associated multiple fractures in the maxillofacial region.On 2D CT images,Le Fort fracture manifested as multiple and complex fractures. Though 2D image was better than 3D image in accurately defining tiny fractures and fractures of deep structures,the diagnosis of Le Fort fracture could not be correctly made solely on 2D image.3D CT clearly and stereoscopically demonstrated the entire shape and orientation of Le Fort fracture,thus facilitating the correct classification of Le Fort fracture.Conclusion 3D CT image is important in providing information about the space relationship of Le Fort fracture,thus very valuable for the preoperative planning.
