Functionalized multi-walled carbon nanotubes( fMWNTs) were prepared with chitosan via controlled surface deposition and crosslinking process and scanning electron microscopy( sEM),Fourier translation infrared spectroscopy( FT-IR) and Xray diffraction( XRD) are used to character properties. A novel high-density chitosan( HCs) was dissolved in f-MWNTs dispersed dilute acetic acid with a maximal concentration of 5. 8%. The hollow fibers can be made by extruding the solution into a dilute alkali solution through a wet-spinning process and the tensile properties of the materials were evaluated by universal tester. The surface property of fibers,pretreated by Helium( He) and the following grafted with gelatin was evaluated with X-ray photoelectron spectroscopy( XPs).As the hollow fibers were intended for neural tissue engineering,its suitability was evaluated in vitro using rat schwann cells( RsC96) as model cells. The cells attachment,proliferation and morphology,were studied by various microscopic techniques. Based on the results,the gelatin grafted HCs / f-MWNTs hollow fibers could be used as a potential cell carrier in neural tissue engineering.

Fenton’s oxidation method was successfully used to synthesize an ideal titania film in situ on NiTi shape memory alloy(sMA) for medical applications. Characterized with scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffractometry, inductively coupled plasma mass spectrometry and electrochemical tests, it is found that the titania film produced by Fenton’s oxidation method on NiTi sMA is nanostructured and has a Ni-free zone near its top surface, which results in a notable improvement in corrosion resistance and a remarkable decrease in leaching of harmful Ni ions from NiTi sMA in simulated body fluids. The improvement of effectiveness to corrosion resistance and the reduction in Ni release of NiTi sMA by Fenton’s oxidation method are comparable to those by oxygen plasma immersion ion implantation reported earlier.

Aim： To determine whether there was any regional variation in the prevalence of azoospermia, oligozoospermia and mean sperm counts in male partners of infertile couples from different parts of India. Methods： Data on 16 714 semen samples analyzed over the past five years from six different laboratories located in five cities of India were collated and evaluated. Results： There was a regional variation in the prevalence of azoospermia. The prevalence of azoospermia was extremely high in Kurnool and Jodhpur （38.3% and 37.4%, respectively）. There was also a regional variation in the prevalence of oligozoospermia （51%） in Kurnool. There was no significant difference in the mean sperm counts in normospermic men. Conclusion： There is a regional variation in the prevalence of azoospermia and oligozoospermia in the male partners of infertile couples from different regions of India. The prevalence of azoospermia in Kumool and Jodhpur is higher than any other worldwide reported literature, Further studies need to be carded out to determine the cause of this. （Asian J Androl 2006 Jan; 8： 89-93）

A 68-year-old man presented with progressive right lower quadrant abdominal pain and tenderness without rebound tenderness, and with constipation during the prior 9 mo. Abdomino-pelvic computed tomography and magnetic resonance imaging demonstrated a dilated appendix forming a fistula to the sigmoid colon. Open laparotomy revealed a bulky abdominal tumor involving appendix, cecum, and sigmoid, and extending up to adjacent viscera, without ascites or peritoneal implants. The abdominal mass was removed en bloc, including resection of sigmoid colon, cecum(with preservation of ileocecal valve), appendix, right vas deferens, testicular vessels, and minimal amounts of anterior abdominal wall; and shaving off of small parts of the walls of the urinary bladder and small bowel. Gross and microscopic pathologic examination revealed an appendix-to-sigmoid malignant fistula secondary to perforation of mucinous adenocarcinoma of the appendix with minimal local spread(stage T4). However, the surgical margins were clear, all 13 resected lymph nodes were cancer-free, and pseudomyxoma peritonei or peritoneal implants were not present. The patient did well during 1 year of follow-up with no clinical or radiologic evidence of local recurrence, metastases, or pseudomyxoma peritonei despite presenting with extensive stage T4 cancer that was debulked without administering chemotherapy, and despite presenting with malignant appendiceal perforation. This case illustrates the non-aggressive biologic behavior of this low-grade malignancy. The fistula may have prevented free spillage of cancerous cells and consequent distant metastases by containing the appendiceal contents largely within the colon.

Cervical cancer is one of the most common gynecological malignancies worldwide. The incidence of cervical cancer ranks second for female malignancies in China. There are about 500,000 new cases of cervical cancer worldwide every year, and more than 80% of them occur in developing countries. About 130,000 new cases occur annually in China, accounting for 28% of the total number of new cases for cervical cancer worldwide. The peak age for diagnosis is 40-60 years old;however, the age of onset is becoming younger in recent years. The incidence of cervical cancer has regional differences, with the incidence in developing countries being higher compared to developed countries. The occurrence of cervical cancer could be effectively controlled by early examination, diagnosis and treatment of precancerous lesions.
