Silk fibroin is a natural polymer with certain water solubility, structural modification, good biocompatibility and biodegradability, which can be used as a drug delivery carrier material. As a promising drug delivery system, drug-loaded silk fibroin nanoparticles can control drug release, reduce toxicity and improve therapeutic effects. In this paper, the basic characteristics of silk fibroin, the preparation methods of drug-loaded silk fibroin nanoparticles and the application of silk fibroin in nanoparticulate drug delivery systems are reviewed, and on this basis, the further development of drug-loaded silk fibroin nanoparticles is prospected.

Appressorium formation is an important event in establishing a successful interaction between the rice blast fungus, Magnaporthe oryzae, and its host plant, rice. An understanding of molecular events occurring in appressorium differentiation will give new strategies to control rice blast. A quick and reliable method to extract total RNA from appressorium is essential for studying gene expression during appressorium formation and its mechanism. We found that duplicate film is an efficient substratum for appressorium formation, even when inoculated with high density conidia. When inoculated with conidia at 1x10(6) ml(-1), the percentages of conidium germination and appressorium formation were (97.98+/-0.67)% and (97.88+/-0.45)%, respectively. We applied Trizol before appressorium collection for total RNA isolation, and as much as 113.6 microg total RNA was isolated from the mature appressoria at 24 h after inoculation. Functional analysis of two genes, MNH6 and MgATG1, isolated from the cDNA subtractive library, revealed that the quantity of RNA was good enough to construct a cDNA (complementary DNA) library or a cDNA subtractive library. This method may be also applicable for the appressorium RNA isolation of other pathogenic fungi in which conidia differentiate into appressoria in the early stages of host infection.

In this study the MTP1 gene, encoding a type III integral transmembrane protein, was isolated from the rice blast fungus Magnaporthe oryzae. The Mtp1 protein is 520 amino acids long and is comparable to the Ytp1 protein of Saccharomyces cerevisiae with 46% sequence similarity. Prediction programs and MTP1-GFP (green fluorescent protein) fusion expression results indicate that Mtp1 is a protein located at several membranes in the cytoplasm. The functions of the MTP1 gene in the growth and development of the fungus were studied using an MTP1 gene knockout mutant. The MTP1 gene was primarily expressed at the hyphal and conidial stages and is necessary for conidiation and conidial germination, but is not required for pathogenicity. The Deltamtp1 mutant grew more efficiently than the wild type strain on non-fermentable carbon sources, implying that the MTP1 gene has a unique role in respiratory growth and carbon source use.

OBJECTIVETo observe the clinical effects of the no-flip procedure with the Chinese Shang Ring when circumcising adult males with redundant prepuce or phimosis, and to discuss its advantages and disadvantages.

METHODSUsing the no-flip Shang Ring technique, we performed circumcision for 167 adult males aged 18 -72 (mean 27.8) years with redundant prepuce or phimosis, and analyzed the clinical data, including the operation time, postoperative complications, ring-removal time, and postoperative appearance of the penis.

RESULTSComplete follow-up data of 94 cases (56.29%) were obtained. The mean operation time was (5.03 +/- 0.71) minutes and the average ring-removal time was (18.83 +/- 6.70) days. The primary postoperative complications were edema (35 cases [37.23%] at 2 weeks and 9 cases [9.57%] at 4 weeks), including 2 severe cases (2.13%), and infection (3 cases [3.19%]). The pain scores were 2.01 +/- 2.46 during the procedure and 4.52 +/- 2.53 at 24 hours postoperatively. Slipping of the outer ring occurred in 1 case, and delayed removal of the ring in 30 cases (31.91%).

CONCLUSIONAdult male circumcision with the no-flip Shang Ring technique is recommended for its short operation time, simple procedure, fewer postoperative complications, less pain, and better incision appearance.

OBJECTIVETo analyze and summarize the clinical and pathological characteristics of intracranial haemangioblastoma and to improve surgery effect.

METHODSeventy-two patients with intracranial haemangioblastoma who were proven by operation and pathology from 1970 to 1988 were analyzed retrospectively.

RESULTSIntracranial haemangioblastoma tends to occur in the hemisphere of cerebellum (83 tumours, 87%) and the age of them ranged from 20 to 40 years (47 cases, 58.3%) mostly. The ratio of men (46 cases) was higher than women (26 cases). The diagnosis of the disease depends on CT and MR substantive haemangioblastoma. The most effective and reliable treatment of intracranial haemangioblastoma is surgical resection.

CONCLUSIONIntracranial haemangioblastoma is benign tumour which can be, cured by total surgical resection. The key recurrence factors include the young age of initial onset, mistaken exploration and incomplete extirpation of tumour.

OBJECTIVETo assess the role of neuronavigation in assisting endoscopic transsphenoidal surgery for pituitary adenomas.

METHODSTen endoscopic endonasal transsphenoidal reoperations for pituitary adenomas were selected. Clinical records were reviewed retrospectively. Five of 10 patients had gigantic adenoma, 3 microadenoma, 2 large adenoma.

RESULTSThe mean setup time was 5 minutes, and the operative time was 50 minutes in image-guided procedures. In all cases, the system worked well without malfunction. Continuous information regarding instrument location and trajectory was provided to the surgeon. Measurements of intraoperative accuracy in the axial, coronal, and.sagittal planes indicated a mean verified system error of 1.5 mm. for pituitary adenomas. After operation, the symptoms relieved in all patients.

CONCLUSIONSNeuronavigation can be applied during endonasal transsphenoidal endoscopic surgery and requires a minimal amount of time. It makes reoperation easier, faster, and safer.
