Bioprocess equipment is of great importance in application of modern industrial biotechnology.With the rapid development of industrial biotechnology,demands for talents capable of understanding the theory,design and manipulation of modern bioprocess equipment increased.The experiences in aspects such as the building of teachers' contingent,construction of teaching materials,innovation of teaching method from the top-quality course construction of Bioprocess Equipment was discussed in this paper.

Objective To provide better emergency and patient services in well-equipped comprehensive hospitals, the organization and wisdom therapeutic strategy are of great importance for the recovery of injured patients from the earthquake zone. Method From 12 May 2008, following the 8.0 Magnitude earthquake in Wenchuan county of Sichuan Province, six Chongqing hospitals with third class in grade A were involved in the rescue of the injured patients with great effort. A total of 533 patients were retreated and followed up from quake zone. All the patients were scored with ISS and AIS system. The profiles of the patients examined, operated and clinical infection investigation were documented. Results Of 533 patients, the number of the patients whose ISS is below 16 is 456 (83.6%), the number between 16 and 25 is 65 (12.2%), and the humor above 25 is 12 (2.3%). The patients were classfled based on their fracture parts as follows: head and neck (n = 42), face (n = 7), chest (n = 114), abdominal and cavitas pelvis (n =81), limb and pelvis (n =314), body surface (n =205), with 180 single fracture site, 139 of them being two combined fracture sites, and 114 of them being above three combined fracture sites. Thirty-two of the patients were suffered from amputation. The number of patients suffered from crushing syndrome reached 21, with 281 surgical operations in hospitals. Seventy-nine patients were suffered from infections including 87.3% of pre-hespital infections. The results from bacteria culture and antibiotic susceptibility showed that the infected bacteria mainly involved in Escherichia coli, Staphylococcus anreus, Staphylococcus haemolyticns, Klebsiella pneumoniae, Baumanii, Aerobacter cloacae, Pseudomonas aeruginosa, C type chain coccus, Bacillus aerogenes capsulatus. The antibiotic susceptibility to diverse bacteria has no obvious changes and exists partial overlapping, and infected patients should be given the treatment of cephalosporin, macrolide antibiotic and so on. Conclusions For the emergency conditions after the catastrophe, the comprehensive hospitals must be prepared to meet large quantities of severe trauma and infection therapy. The scientific selection of antibiotics in the combinative therapy is of great importance to the enhancement of early specific treatment, prevention of severe trauma complications and rehabilitation of patients.

OBJECTIVETo explore the regional anatomy of the rectum including the perirectal fasciae and spaces.

METHODSTwenty-one cadavers (15 males and 6 females) were embalmed and their vessels were visualized by injection with color dye. From the cadavers, 30 hemipelvis and 6 three-quarter pelvis were harvested. The perirectal fasciae and spaces and the pelvic autonomic nerves were dissected and examined.

RESULTSThree tissue layers were dissected from the inside to the periphery including the proper rectal fascia enveloping the mesorectum, the presacral fascia, and the piriformis fascia fused with the sacral periosteum. The mesorectum comprised 2 parts with the classical posterolateral fat covered by the proper rectal fascia posteriorly and the anterior fat covered by the posterior layer of Denonvilliers fascia anteriorly. Extending anteriorly to the anterior layer of Denonvilliers fascia, the presacral fascia bisected the space between the mesorectum and the piriformis fascia into the retrorectal space and the presacral space. The retrorectal space extended cranially to the left retrocolic space, anterior to the space between the 2 layers of Denonvilliers fascia(prerectal space).

CONCLUSIONSFrom the inside to the periphery, the proper rectal fascia, the presacral fascia, and the muscular fascia are distributed in an annular pattern around the mesorectum. The presacral fascia divides the perirectal space into 2 annular parts, the central retrorectal space and the peripheral presacral space. The retrorectal space is the ideal surgical plane for total mesorectal excision.
