ObjectiveTo investigate sleep disorder of patients with depression and find out the regularity.Methods78 depression cases in the east-region of Shenyang were evaluated by Pittsburgh Sleep Quality Index (PSQI) questionnaire and mental health symptom checklist-90 (SCL-90). The results were contrasted with normal control group.Results63 depression cases (80%) had sleep disorder (PSQI scores≥8) and were significantly higher than normal control group. The PSQI evaluation showed that sleep quality, enter-sleep time, sleep efficiency, sleep disorder, hypnotige drugs, function of daytime and total scores of PSQI of the depression group were significantly higher than that of normal control group (P<0.05～0.01). The SCL-90 test showed that scores of somatic, obsessive, depressive, anxiety, phobia, paranoid and mental-illness, etc. and total quota of bad-sleep quality group were significantly higher than that of the fine-sleep quality group (P<0.05～0.01).ConclusionDepression patients have significantly descent in sleep quality, latter is often closely related to the mental psychotic expressiveness of somatic, obsession, depression, anxiety, phobia, etc.

Objective: This study aimed to observe the long-term effect of Pseudomonas aeruginosa preparation used in peritoneal injection of advanced colorectal cancer patients during surgery. Methods: A total of 83 colorectal cancer patients who received surgery between September 2006 and March 2008 were enrolled in this study. The patients were divided into two groups. Palliative resection and a 10 ml P. aeruginosa peritoneal injection were performed in 30 of 83 patients in the treatment group. Simple palliative resection was conducted in the other 53 patients, which comprised the control group. Both groups were then treated by regular chemotherapy and radiotherapy. Results:The follow-up visit was completed in 79 of 83 patients, with a high follow-up rate of 95.2%. No significant difference was found in the five-year overall survival time between the two groups (P=0.403). However, the five-year median survival time in the control group was only 13.9 ± 2.14 months, whereas that in the treatment group was 17.2 ± 2.12 months. Conclusion: Within a short period, peritoneal injection of P. aeruginosa during surgery could confer certain survival advantages for advanced colorectal cancer patients. However, the long-term effect of this therapy remains unknown.

Objective To discuss the treatment strategy of knee dislocation and to evaluate its outcome.Methods Thirty-six patients with unilateral knee dislocation treated with individualized protocol were studied retrospectively,including 22 males and 14 females with an average age of 35 years (range,19-72 years).There were 30 acute and 6 chronic knee dislocations.According to the modified Schenck's classification of knee dislocation,there were 7 KD- Ⅰ and 23 KD-Ⅲ cases in the acute category,and all 6 chronic cases were KD-Ⅲ.Seven acute KD- Ⅰ and 6 chronic KD-Ⅲ cases underwent one-stage arthroscopic surgery.In 23 acute KD-Ⅲ cases,2 were treated conservatively with splint or brace due to advanced age,18 with staged surgery,3 with one-stage surgery due to concomitant vascular and nerve injury.Functional and clinical evaluation was conducted at final follow-up.Results All 36 patients were followed up for an average of 27 months (range,18-36 months).The Lysholm score (82.0±11.4),Tegner score (5.5±1.3),and knee range of motion (118.3°±19.2°) at final follow-up showed a statistically significant improvement compared with preoperative results (P＜O.O1).Eight (23.5％) patients had residual knee instability:posterior drawer test and Sag sign were positive (++ or +++) in 8 knees,valgus instability (++) in 1 and varus instability (+++) in 1.The remaining 28 knees were stable.Conclusion Special attention should be paid to rotational knee dislocation with single cruciate ligament rupture.Properly individualized treatment plan is the key to optimal outcome.Arthroscopic surgery can lead to successful outcome.Early one-stage arthroscopic surgery is recommended for acute KD-Ⅰ and chronic KD-Ⅲ dislocation,staged arthroscopic surgery for acute KD-Ⅲ dislocation.

Objective To discuss the application value of 18F-FDG PET/CT in diagnosis of colorectal cancer. Methods We retrospectively analyzed the data of 186 patients who were diagnosed as colorectal cancer by 18F-FDG PET/CT. We classifed all cases according PET/CT imaging into position group and type group,and calculated SUV (maximum standard uptake value) of tumor tissue, and compared with normal tissue. Results There were 112 cases of rectal cancer,27 cases of carcinoma of sigmoid, 17 cases of carcinoma of cecum,16 cases of ascending colon carcinoma,14 cases of carcinoma of descending colon according to positions via PET/CT. There were 68 cases of protrude type,57 cases of ulcerative type,34 cases of infiltrating type,27 cases of colloid adenoma according types via PET/CT. The SUV of tumor tissue was higher than normal value,the difference had statistical significance. Conclusion 18F-FDG PET/CT has high application value in colorectal cancer diagnosis, positions and types.

Objective: Clone, express and purify human recombinant calreticulin (CRT). Methods: Human CRT cDNA was amplified from total RNA of human lung cancer cell line A549 cells by RT-PCR. Then, PCR product was subcloned into prokaryotic expression vector pET-15b. After sequencing, this recombinant plasmid was transformed into E.coli. Rossetta. Recombinant CRT was expressed in host cells by IPTG induction. Resulted protein was purified by Ni-NTA resin under denature condition and dialyzed to recover its native structure. SDS-PAGE and Western blot method were used to identify the expression and purification of reconbinant CRT. Results: Human CRT cDNA was cloned from total RNA of A549 cells. CRT prokaryotic expression vector pET-15b-crt was constructed. Reconbinant CRT was induced to express in E.coli and purified by Ni-NTA affinity chromatograph. Conclusion: A method for prokaryotic expression and purification of human recombinant CRT was successfully established. This method laid a foundation for the subsequent CRT research.
