Objective:To investigate the modulating effects of anti-epidermal growth factor monoclonal antibody Cetux- imab(C225)on the ehemosensitivity and radiosensitivity in a Docetaxel-resistant human lung adenocarcinoma cell line SPC-A-1/doeetaxel.Methods:Radiosensitivity of SPC-A-1/docetaxel was determined by clone formation experiment and quantified by calculating the enhancement ratio(ER).The growth inhibition of SPC-A-1/docetaxel cell line caused by C225 or combination of C225 and Docetaxel in different orders was detected by MTT assay.The effect of C225 on cell cy- cle distribution and apoptosis was determined by flow cytometry.Results:C225 combined with radiation significantly de- creased the number of the cell clones than radiation alone;the D_0 values were 1.73 Gy for the former and 2.39 Gy for the latter,and the enhancement ratio was 1.38.C225 alone at concentration up to 1000?g/ml for 48h had neither cytotoxic nor eytostatie effect on SPC-A-1/docetaxel in vitro.C225 administration followed by Docetaxel significantly decreased the ICw of Docetaxel(85.2?g/ml vs 128.7?g/ml).Flow cytometry demonstrated that C225 exposure induced apoptosis of SPC-A-1/docetaxel cells in a time-dependent manner.The cell in the G_0/G_1 fraction increased from(43.80?4.46)% to (60.50?6.57)%(P

Objective To study the clinical and pathologic features,histological criteria and pathologic factors contributing to diagnosis of mixed epithelial and mesenchymal tumors(mixed m?llerian tumors,MMT)of the uterus.Methods A retrospective study of 102 cases of MMT of the uterus (74 adenofibromas including 9 recurrent cases,3 atypical polypoid adenomyomas,2 carcinofibromas,10 adenosareomas and 13 carcinosarcomas)was undertaken.Clinical records,gross features and tissue slices were reviewed.The follow-up data were analysed.Results The most common symptom was vaginal bleeding.Clinical signs included pelvic mass,uterine polyps,and enlarged uterus.Benign MMT usually presented as exophytic polypoid masses extending into the uterine cavity or protruding through the external os,often broad-based,lobulated and papillary.It was hard to distinguish low-grade malignant MMT from the benign ones by gross appearance.High-grade malignant MMT had the common gross features of carcinoma and sarcoma.Histologically,MMT showed a biphasic differentiation of mesenchymal and epithelial components.MMT were classified according to whether these elements were benign or malignant.Nine cases of adenofibroma without unique features for the diagnosis of adenosarcoma recurred at postoperative intervals of 3 to 96 months.Recurrent tumors were almost always confined to the original site.Conclusions Uterine MMT tumors according to WHO diagnostic criteria are not rare.The differential diagnosis depends on a multifactorial analysis.The recurrent adenofibromas may be a kind of borderline tumors with benign appearances and malignant behavior.

In order to study the contraindications of the compatibility of Flos Genkwa-Radix et Rhizoma Glycyrrhizae, in this study, the solubilizing and poisoning essence were explored. In this experiment, chromatographic assay, field emission scanning electron microscopy, MTT cytotoxicity evaluation, and other methods were used to study the main chemical components, morphology and toxicity of the ethyl acetate part of Flos Genkwa and its co-decoction with glycyrrhizic acid, in order to clarify Flos Genkwa-Radix et Rhizoma Glycyrrhizae incompatibility provides a new idea for the research on incompatibility of Flos Genkwa-Radix et Rhizoma Glycyrrhizae. The results showed that after co-decoction of the ethyl acetate part of Flos Genkwa with glycyrrhizic acid, high performance liquid chromatography (HPLC) detected the dissolution of the toxic component yuanhuacine of 54.8%, while yuanhuacine chromatographic peak was not detected in the Flos Genkwa ethyl acetate part of the single decoction. The increase of co-decoction dissolution rate was observed by scanning electron microscopy, and it was found that glycyrrhizic acid uniformly dispersed the fat-soluble components of Flos Genkwa into nano-scale particles, which improved the solubility and stability in the solution. Furthermore, the results of cytotoxicity evaluation showed that the survival rate of cells decreased after co-decoction, 4',6-diamidino-2-phenylindole (DAPI) staining also gave the same results. In summary, the co-decoction of the ethyl acetate part of Flos Genkwa with glycyrrhizic acid promotes the dissolution of the toxic component yuanhuacine, and makes the part form uniformly distributed nanoparticles, which is conducive to the absorption of the ingredient and increases the toxicity.

?AIM: To explore the relation of homocysteine ( Hcy ) and its metabolic related indicators with primary angle-closure glaucoma ( PACG) .?METHODS: In this study, a total of 150 PACG patients and 150 controls were enrolled. The patients with PACG were diagnosed by applanation tonometer, Humphrey perimetry ( HVF ) , optical coherence tomography ( OCT ) , gonioscope. The normal controls were recruited from physical examination center. Blood samples were collected and the plasma was used to determine homocysteine, vitamin B12 and folic acid. DNA was extracted to determine the methylenetetrahydrofolate reductase ( MTHFR ) C677TT genotype and gene polymorphism.?RESULTS:There was a statistically significant difference (t=2. 04,P=0. 04) in mean homocysteine levels between patients with PACG ( 16. 11 ± 1. 66μmol/L ) and controls (15. 74± 1. 52μmol/L). The level of vitamin B12 in PACG group was 248. 09 ± 119. 07pg/mL and the control group was 230. 21 ± 142. 93pg/mL. No statistically significant difference was found on the vitamin B12 level between the two groups ( t = 0. 84, P = 0. 40 ). The folic acid levels showed no statistically significant differences( t=1. 65,P=0.17) between the PACG group(12. 02±7. 81ng/mL) and the control group (13. 15 ± 6. 25ng/mL). The frequency distribution of the MTHFR C677T genotypes was found to be significantly associated (χ2 =6. 2,P<0. 05) with PCAG (CC 84. 7%, CT 4. 7%, TT 10. 7%) as compared to the controls (CC 94. 7%, CT 2. 0%, TT 3. 3%). The frequency distribution of TT genotypes of MTHFR C677T in the PACG group was significantly higher than that in the control group. Moreover, our findings showed significant difference (χ2=14. 2,P<0. 05) between the allele frequency of the C677T single nucleotide polymorphism within the MTHFR gene in POAG patients ( T 87. 0%, C 13. 0%) and the control group(T 95. 7%,C 4. 3%) .?CONCLUSION: These results show that the Hcy level and the TT genotypes of MTHFR C677T were higher in the PACG patients than in controls. Therefore, our data suggests that high Hcy level and the related indicators are associated with high PACG risk.

Objective To study the clinical effect of the BacFuse for the lumbar disc herniation(LDH) and to discuss the affect for symptom of patients and structure of spine.Methods Collected the patients suffered from LDH retrospectively who had been implanted the BacFuse.There were 25 patients (29 surgical levels) included in the study.The clinical and X-ray assessment have been done on preoperation,postoperation,3 month,6 month and 12 month.Clinical index used visual analogue scale (VAS) score,oswestry disability index (ODI) score and Japanese Orthopaedic Association (JOA) score assessed clinical symptom and physical function.The intervertebral angle,posterior disk height and foraminal height were measured in X-ray.The patients were taken CT at preoperation and postoperation.The area and distance of herniated disc were measured in CT scan.Results In the aspect of clinical effect,25 cases were finished operation successly.The VAS score decreased from (6.61±1.29) points on preoperation to (2.78±1.00) points on the last follow-up,the ODI score decreased from (31.9±8.3) points to (15.9±6.4) points,the JOA score increased from (9.6± 3.0) points to (18.8± 3.2) points.In the aspect of spine structure,the intervertebral angle decreased from 10.1°±5.4° on preoperation to 8.4°±4.9° on the last follow-up,the posterior disk height increased from (0.65±0.29) cm on preoperation to (0.78±0.27) cm on the last follow-up and the foraminal height increased from (2.01±0.35) cm on preoperation to (2.16±0.37)cm.There was significant difference on posterior disk height and foraminal height between preoperation and postoperation,while the posterior disk height lost (0.07±0.12) cm (9.3％) and foraminal height lost (0.06±0.19) cm (2.7％).The CT showed that area of herniated disc decreased from (4.10±0.78) mm to (3.72±0.66) mm (9.3％) and distance of herniated disc decreased from (96.4±37.8) mm2 to (83.8±31.1) mm2 (7.4％).Conclusion BacFuse can relieve symptom and affect the biomechanics of the spine,makes the herniated disc retract partially,playing a Internal Retractor role in spine,and it is a new effective therapy for LDH.
