Objective To explore the imaging features of breast cancer by molybdenum target roentgenography in order to improve the diagnostic level. Methods The mammographic features of 68 cases with breast cancer confirmed surgically and pathologically were studied retrospectively. Results Masses with high density, spicule signs and lobulate margins were found in 61, 43 and 32 cases, respectively. Calcification was found in 29 cases (42 6%), in which only 7 cases of calcification without mass were found. Conclusion The masses and calcification are the main radiological features in breast cancer. The consciousness of comprehensive examination should be emphasized in the diagnosis of breast cancer.

Objective To explore the curative effect of microsurgery via posterior approach through the sigmoid sinus in the treatment of secondary trigeminal neuralgia. Methods Clinical data of 37 cases of trigeminal neuralgia secondary to cerebellopontine angle (CPA) tumor from October 2000 to July 2006 were studied, including 18 cases of cholesteatoma, 8 cases of meningoma, 6 cases of acoustic neuroma, and 5 cases of trigeminal schwannoma. All tumors were removed with microsurgery through a posterior approach by way of the sigmoid sinus. Results A total resection was achieved in 23 cases, a subtotal resection in 10 cases, and a partial resection in 4 cases. Symptoms of neuralgia disappeared in 35 cases (including 32 cases of immediate relief and 3 cases of relief 2 months after operation). There was no improvement in 2 cases. Conclusions Microsurgery via posterior approach through the sigmoid sinus in the treatment of secondary trigeminal neuralgia is safe and effective.

Objective To evaluate the therapeutic effects and safety of trabeculectomy combined with Schlemm canal suture implantation in patients POAG). Design Retrospective, noncomparative case series. Participants 11 patients (19 eyes)with POAG. Methods Two layers of scleral flap were made and the deeper one was dissected. The outer wall of Schlemm canal was cut away. 6-0 nylon thread was implanted between the two cut ends of the canal. Penetrating trabeculectomy was performed and followed with peripheral iridectomy. Superficial scleral flap was sutured. Main Outcome Measures The postoperative observation included intraocular pressure (IOP), formation of the anterior chamber, inflammatory reaction, visual acuity, complications and situation of filtering bleb. Results The mean postoperative follow-up period was 18.05?12.78 months (ranging from 6 to 48 months). There was significant statistical difference between preoperative and postoperative IOPs(31.23?9.72mmHg VS 15.11?6.13mmHg) (t=6.769, P=0.000). The postoperative investigation of IOP for 11 cases (19 eyes) after using medicine showed that IOP≥22mmHg only 1 case. The efficiency was 94.74%. Filtering blebs formed in 6 cases (8 eyes)(42.11%), including the case with IOP≥22mmHg. There was no significant difference in change of preoperative and postoperative IOP in patients with or without filtering blebs with t-test (t=-1.662, P=0.071). The anterior chamber formed well in each case postoperatively. Hyphemia appeared in 4 eyes (21.05%). Hypertonia oculi (IOP≥22mmHg) and hypotonia oculi (IOP≤6mmHg) appeared occasionally in 3 eyes(15.78%) and 11 eyes(57.89%) respectively. Postoperatively,no fibrinous exudates in anterior chamber, choroidal detachment and other complications occurred in any case. Conclusions The control of IOP appears to be good after the surgery of trabeculectomy combined with Schlemm canal suture implantation. It is a promising approach for glaucoma and good with fewer postoperative complications, easier postoperative management and deserve further development.

Objective:To establish a method based on the iPLEX analysis of MassARRAY mass spectrometry platform to detect multiplex genetic mutations among Chinese lung cancer patients. Methods:We reviewed the related literature and data of lung cancer treatments. We also determined 99 mutation hot spots in 13 target genes, namely, EGFR, KRAS, ALK, FGFR1, FGFR2, FGFR3, PIK3CA, BRAF, PTEN, MET, ERBB2, AKT1, and STK11, which are closely related to the pathogenesis, drug resistance, and metastasis of lung cancer and are associated with relevant transduction pathways. A total of 297 primers comprising 99 paired forward and reverse amplification primers and 99 matched extension primers were designed by using Assay Design in accordance with the mutation label and format requirements of the MassARRAY platform. The detection method was established by analyzing eight cell lines and six lung cancer specimens;the proposed method was then validated through comparisons with a LungCarta kit. The sensitivity and specificity of the proposed method were evaluated by directly sequencing EGFR and KRAS genes in 100 lung cancer cases. Results:The proposed method could detect multiplex genetic mutations in the lung cancer cell lines, and this finding is consistent with that observed using previously reported methods. The proposed method could also detect such mutations in clinical lung cancer specimens;this result is also consistent with that observed by using the LungCarta kit. However, an FGFR2 mutation was detected only by using the proposed method. The measured sensitivity and specificity were 100%and 96.3%, respectively. Conclusion:The proposed MassARRAY technology-based method could detect multiplex genetic mutations among Chinese lung cancer patients. Indeed, the proposed method can be potentially applied to detect mutations in cancer cells.
