The fermentation conditions of lipase production by Geotrichum candidum Y162 were optimized. Initially, the most suitable carbon olive oil, nitrogen source soybean flour and NH4Cl, salt BaCl2 and MgCl2 were selected according to single factorial experiments respectively. Based on the result, screening methodology Plackett-Burman design was used to evaluate the effects of twelve factors related to lipase production and three statistically significant factors olive oil, BaCl2 and NH4Cl were selected. The path of steepest ascent was used to approach the optimal region of lipase production subsequently. Then, the optimal combined concentration for maximum enzyme activity were further optimized by response surface methodology and determined as follows: olive oil 2.35%, BaCl2 0.36%,and NH4Cl 4.69%.The optimization of culture conditions of G.candidum Y162 led to a 2.25-fold increase in lipase production relative to initial result 14.16 U/ml, which indicate that single factor in combination with response surface methodology is an effective method for optimization of lipase production conditions by G.candidum Y162.

OBJECTIVETo investigate the levels of secretions from the prostate and seminal vesicles and their association with the expressions of aquaporins (AQP) in the prostatic tissue and seminal vesicles of castrated rats.

METHODSWe randomly divided 18 eight-week-old male SD rats into a control, a castration, and a testosterone (T) replacement group. Four weeks after surgical castration, we detected the plasma T level and measured the volumes of the secretions and the expressions of AQPs 3, 7, and 10 - 12 in the prostate and seminal vesicles of the rats.

RESULTSThe plasma T level was significantly lower in the castrated models ([30. 98 ± 28. 84] ng/dl) than in the rats of the control ([700.78 ± 123.8] ng/dl) and T replacement groups ([688.08 ± 132. 47] ng/dl) (P <0. 05). The castration group, in comparison with the control and T replacement groups, showed remarkably reduced ratios of prostatic secretion volume / prostate weight ([11.1 ± 0.30] vs [2.32 ± 0.61] and [2.13 ± 0.56] %, P <0. 05) and seminal vesicle secretion volume / seminal vesicle weight ( [4. 78 ± 1. 97 ] vs [57. 36 ± 11. 86] and [55. 74 ± 7. 21] %, P < 0. 05). Immunohistochemistry revealed the expressions of AQPs 3 and 7 in the epithelial envelop and cytoplasm and that of AQP 11 the in endothelial envelop and cytoplasm of the prostate and seminal vesicles. Western blot exhibited significantly lower expressions of AQPs 3, 7, and 10 - 12 in the prostate and seminal vesicles of the castrated rats than in the animals of the control and T replacement groups (P <0. 05).

CONCLUSIONSignificant decreases of the secretions from the prostate and seminal vesicles may be related to the reduced expressions of AQPs 3, 7, and 10 - 12 in the prostatic tissue and seminal vesicles in castrated rats.

Objective To decrease tumor local recurrence after abdominoperineal resection (APR)for low rectal cancer using cylindrical abdominoperineal resection. Methods From February 2009 to February 2010 cylindrical APR was performed in 15 patients of advanced ultralow rectal cancer at the Department of General Surgery, Qilu Hospital of Shandong University, according to the standard protocol as described by Holm. The procedure involves careful mobilization of the mesorectum as far down as the origins of the levator muscle. Ater stoma formation, the abdomen is closed, the patient is rotated into the prone position, and an extended perineal dissection is performed. This includes the sphincter complex and the inferior surface of the levators to a point laterally where they originate on the pelvic sidewall. This point should be just inferior to the level where the abdominal procedure was terminated. The coccyx is often removed in continuity with the main specimen to improve direct visualization of the dissection.Results The cylindrical technique removed more tissue in the distal rectum. There was no bowel perforation, perineal wounds were primary healing. One patient developed perineal seroma. One patient developed peritoneocele hernia of pelvic floor. Conclusions Cylindrical APR performed in the prone position for low rectal cancer removes more tissue around the tumor that leads to a reduction in intraoperative perforations, which should reduce local disease recurrence.

To ensure the quality and safety of Panax notoginseng, a method for the simultaneous determination of 10 mycotoxins in Panax notoginseng was developed using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The sample was extracted with acetonitrile and purified by HLB multifunction cleanup column. The separation was performed on a Phenomenex Kinetex XB-C18 column by gradient elution using methanol and 5 mmol·L(-1) ammonium acetate as mobile phase. The targeted compounds were detected in MRM mode by mass spectrometry with electrospray ionization (ESI) source operated in both positive and negative ionization modes. The linear relationships of the 10 mycotoxins were good in their respective linear ranges. The correlation coefficients (r) ranged from 0.9981 to 1.0000. The LOQs of the 10 mycotoxins were between 0.15 and 8.6 μg·kg(-1). The average recoveries ranged from 73.8% to 107.0% with relative standard deviations (RSDs) of 0.10%-10.9%. The results demonstrated that the proposed method was sensitive and accurate, and suitable for the mycotoxins quantification in Panax notoginseng.

AIM: To study the immunological protection of H. pylori vaccine with chitosa as adjuvant. METHODS: One-grade female BALB/c mice were randomly divided into nine groups and immunized by ①PBS alone; ②chitosan solution alone; ③chitosan particles alone; ④H. pylori antigen alone; ⑤H. pylori antigen plus chitosan solution; ⑥H. pylori antigen plus chitosan particles; ⑦H. pylori antigen plus CT; ⑧H. pylori antigen plus chitosan solution and CT; ⑨H. pylori antigen plus chitosan particles and CT. At 4 weeks after the last immunization, these mice were challenged by alive H. pylori(1?1012CFU/L) twice at two-day intervals. At 4 weeks after the last challenge, these mice were all killed and gastric mucosa were embedded in paraffin, sectioned and assayed with Giemsa staining. The other gastric mucosa were used to quantitatively culture with H. pylori. ELISA was used to detect H.pylori IgA in saliva and gastric mucosa and anti-H.pylori IgG, IgG1, IgG2a in serum, and immunohistochemical method was used to examine sIgA in gastric mucosa. RESULTS: ①In the groups with chitosan as adjuvant, 60% mice achieved immunological protection, which was according to that with CT as adjuvant (58.33%), and was significantly higher than H. pylori antigen alone and other groups without H. pylori antigen(P0.05)and were significantly higher than those in non-adjuvant groups, while those in the groups with chitosan plus CT were significantly higher than those in the group with CT as an adjuvant(P

OBJECTIVETo observe the short-term clinical effectiveness of bone ring graft technique and to summarize the key points of related surgical operation to provide comprehensive clinical guidelines.

METHODSFifteen patients with severe alveolar bone absorption were selected to receive bone ring grafting and immediate dental implant. Final fixed prostheses were cemented five months after initial implantation. Cone beam CT scans were conducted on all subjects before the procedure, as well as four months post-operation to evaluate alveolar bone height and level of bone height and absorption around the implants. Four to six months after prosthesis installation, each implant's Jemt classification, gingiva attachment, and probing depth (PD) were analyzed. The difference of PD between implants and adjacent teeth, as well as the difference of the bone absorption between labial and lingual sides, was compared. The survival rate of the bone ring and the retention rate of implants were calculated. Complications and patient satisfaction were also investigated.

RESULTSBone graft survival rate was 94.4% and dental implantation retention rate was 100% four months post-operation. Average bone level increase was (6.06 +/- 1.06) mm, average bone absorption was (1.33 +/- 0.84) mm, and average bone thickness at the neck of the dental implant body was (6.94 +/- 0.73) mm. Approximately 4 to 6 months after crown restoration, average bone level increase was (5.62 +/- 1.03) mm, average bone absorption was (1.51 +/- 1.02) mm, and average bone thickness at the neck of the dental implant body was (6.77 +/- 0.72) mm. The PD around the implant body and the adjacent teeth was statistically insignificant. No major post-operative complication was observed, restorations were successful, and patient satisfaction level was high.

CONCLUSIONBone ring graft technique and immediate dental implantation are relatively simple to perform, and these techniques facilitate reduction in required treatment time. Short-term effect is reliable and satisfactory, whereas long-term outcomes require further follow up and study.
