Atomic layer deposition has been employed for postsynthesis treatment of octadecyl bonded silica (ODS) as a typical reversed-phase stationary phase for high performance liquid chromatography (HPLC) ,in an effort to alleviate peak tailing for basic compounds. With hexamethyldisilazane( HMDS) as an endcapping agent,the ODS packing materials were heated to 250℃,and maintained at that temperature for 6 h,affording packing materials which are highly inert to basic compounds. Chromatographic performance in terms of retention factor and tailing factor of the resulting phases was evaluated using phenol/pyridine and naphthalene/ami-triptyline pairs as probes. The results were compared with those for the same packing treated by liquid phase method and for the commercial products including Zorbax SB-C_(18) and Kromasil C_(18). The separation characteristics of the ODS phase obtained by atomic layer deposition appear to be superior to that by liquid phase method and,comparable with or even better than the commercial products studied. Being solvent-free process amenable to mass production,the described method provides an economical and eco-friendly approach to manufacturing HPLC packing materials on industrial scale.

Objective To evaluate the clinical value of laparotomy,transvaginal surgery,and lapaioscopic surgery in treating benign ovarian cyst.Methods We retrospectively analyzed 227 patients with benign ovarian cyst who underwent laparotomy,transvaginal surgery,or laparoscopic surgery.The duration of the operation,amount of blood loss,hospitalization time,anal exhaust time,temperature recovery time.outof-bed time,usage of analgesics,postoperative morbidity,and hospitalization cost were analyzed.Results There were significant differences in above indicators between the patients undergoing transvaginal surgery or laparoscopic surgery and those undergoing laparotomy.Conclusion Transvaginal surgery and laparoscopic surgery are minimally invasive and safe in treating benign ovarian cyst.These 3 surgical approaches have distinct advantages and disadvantages.The clinicians should choose the appropriate surgical approach for benign ovarian cyst according to the patient's condition.

Objective In order to study the etiology and the hearing status of the deaf students in Hubei province, a survey was carried out from April 1999 to June 2000.Methods A total number of 813 deaf students in Hubei province were examined with audiometer and investigated through questionnaire. The pedigress analysis was conducted in deaf students with family history.Results The pedigrees of 227 familes with deafness were obtained, the inheritance pattern of 167 families could be ascertained. 232(28.5%) deaf students were diagnosed congenital deafness, 581 (71.5%) students were diagnosed acquired deafness. The degrees of deafness could be ascertained with 359(44.1%) students of profound deafness, 323(39.7%) students of severe deafness, 111(13.7%) students with moderate to severe deafness, 11(1.4%) students of moderate deafness, and 9(1.1%) students of mild deafness.Conclusion The hearing loss of deaf students is very serious, and genetic factor and ototoxic antibiotics were a principal causation in the occurrence of deafness.

Objective To analyse the frequeney and pattern of lymph node metastasis in bilateral papillary thyroid microcarcinoma (PTMC), and establish the optimal surgical strategy for patients. Methods From March 2006 to August 2008, 58 bilateral PTMC patients received surgical treatment and the tumour characteristics, the frequency and pattern of lymph node metastasis and surgical management of these patients were retrospectively analysed. Results Forty-four patients received total thyroideetomy and 14 patients received near-totsl thyroideetomy, 47 patients received central compartment (level VI ) dissection and cervical level Ⅱ,Ⅲ, IV node exploration by internal jugular vein exposure,10 patients received level Ⅵdissection and unilateral cervical dissection and 1 patient received bilateral cervical dissection. The mean tumor diameter was (6.28 + 2.23) mm and 26 patients (44.8%) had node involvement, 88.5%(23/26) pa-tients had only level Ⅵ node involvement. Only 1 patient had node involvement in the jugular chain without level Ⅵ node involvement, 2 patients with level Ⅵ node involvement were associated with another cervical compartment nodes involvement. Conclusions Bilateral PTMC has high incidence of lymph node metasta-sis. The cervical level Ⅵ is the most common site of node involvement for bilateral PTMC and the surgical strategy for bilateral PTMC should include the cervical level Ⅵ dissection routinely.
