Objective To study sperm mRNA transcript expression of CRISP2 gene in the semen of patients with different types of spermatogenetic failure. Methods A total of 150 male infertility patients were divided into normal group, asthenozoospermia group and oligozoospermia group(n=50 for each group). Total RNA was extracted from sperm cells. Re-al-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) method was used to detect CRISP 2 gene mRNA levels in three groups. Results There was a significantly higher expression of CRISP2 in normal group (10.281 ± 2.173) than that of asthenozoospermia group (2.092±0.969, P＜0.05). There was no significant difference in the expression of CRISP2 between normal group and oligozoospermia group (9.420±2.794, P>0.05). The relative expression of CRISP2 was sig-nificantly lower in asthenozoospermia group than that of oligozoospermia group (P＜0.05). Conclusion The CRISP2 expres-sion was significantly different in patients with different types of spermatogenic failure. The reduced expression of CRISP 2 may lead to the decreased sperm motility.

Objective To evaluate DOG1 as an immunohistochemical marker for GIST.Methods From Jan 1987 to Sep 2008,210 consecutive cases including 137 GISTs as well as 73 non-GIST sarcoma were evaluated for clinicopathological characteristics and immunostained for DOG1 antibodies.Result Immunoreactivity for DOG1 was detected in 110 of 137 GIST cases (80.3%),3 out of 11 CD117negative GISTs were DOG1-positive.Only 1 of 73 non-GIST case was positive for DOG1.The expression of DOG1 in GIST is associated with the location of tumor,cell density,nuclear pleomorphism and Fletcher grading criteria.The postoperative 1-,3-,5-year overall survival for DOG1 negative and positive patients was 81.3%,74.5%,74.5% and 98.5%,85.9%,83.2%,respectively,P = 0.034.Conclusion DOG1 was a sensitive and specific marker for GIST in gastrointestinal mesenchymal tumors (GIMT).

Objective To investigate the application value of two kinds of endometrial preparation in patients with thin endometrium of frozen thawed embryo transfer cycle.Methods A retrospective analysis of the clinical data of 82 cycle of 76 patients was carried out.According to the difference of the endometrial preparation,the two groups were divided into two groups.One group was progynova group (42 cycles),and the other group was femonston group (40 cycles).Baseline information,endometrial status and pregnancy outcome were compared between the two groups.Results There was no significant difference in baseline data (age,years of infertility,body mass index,basal hormone level) between the two groups.There was no significant difference in endometrial thickness[progynova group (5.52 ± 0.74) mm,femonston group (5.33 ± 0.66) mm,t =1.290,P =0.203],endometrial volume (progynova grouP ＜ 2mL and ≥ 2mL 38 patients and 4 patients,that of femonston group 36 cases and 4 cases,x2 =0.005,P =0.942),endometrial type (progynova group A,B,C type 35 cases,7 cases,0 case,those of emonston group 34 cases,6 cases,0 case,x2 =0.043,P =0.836) and blood flow (progynova group Ⅰ + Ⅱ and Ⅲ 34 cases and 8 cases,those of femonston group 35 cases and 5 cases,x2 =0.658,.P =0.417) between the two groups before treatment.After administration,endometrial thickness [progynova group (6.90 ± 0.62) mm,femonston group (7.60 ± 0.63) mm,t =5.04,P =0.000],neointimal growth [progynova group (1.67 ± 0.48) mm,femonston group (3.20 ± 0.61) mm,t =12.74,P =0.000],ratio of endometrial volume more than or equal to 2 mL [progynova group 52.38 ％ (22/42),femonston group 80.00％ (32/40),x2 =6.95,P =0.008],and ratio of endometrial blood flow type Ⅲ [progynova group 38.10％ (16/42),femonston group 70.00％ (28/40),x2 =8.387,P =0.004] of femonston group were higher than those of progynova group.The dosage[progynova group (112.43 ± 16.39)mg,femonston group (78.85 ± 10.17)mg,t =11.08,P =0.000] was lower than that of progynova group,and the difference was statistically significant.There was no significant difference in the two groups in endometrial type (progynova group A,B,C 30 cases,12 cases and 0 case,those of femonston group 28,12 and 0,x2 =0.020,P =0.887) after the treatment.There was no significant difference in the number of transplanted embryos (progynova group 1.78 ± 0.47,femonston group 1.77 ± 0.42,t =0.108,P =0.914),high quality embryo rate [progynova group 74.67 ％ (56/75),femonston group 73.24 ％ (52/71),x2 =0.039,P =0.844],implantation rate [progynova group 14.67 ％ (11/75),femonston group 16.90％ (12/71),x2 =0.137,P =0.711],biochemical pregnancy rate[progynova group 38.10％ (16/42),femonston group 40.00％ (16/40),x2 =0.031,P =0.860] and clinical pregnancy rate [progynova group 28.57 ％ (12/42),femonston group 32.50％ (13/40),x2 =0.149,P =0.699] between the two groups.Conclusion Femonston with less dosage,better improvement of the endometrial thickness,endometrial volume,endometrial blood flow of patients with thin endometrium of patients can obtain similar pregnancy outcomes compared with progynova.

Objective To explore the clinical outcomes of laparoscopic appendectomy in acute and chronic appendicitis,and sum up the surgical experiences of lapaproscopic appendectomy.Method In this study 129 cases of appendicitis at the Department of Gastroentrological Surgery,Peking University People's Hosptial were collected retrospectively from June 2008 to December 2009.The clinical results of laparoscopic and open procedures for acute appendicitis and the outcomes of laparoscopic operation for acute and chronic appendicitis were compared.Results For acute appendicitis,the length of hospitalization [(4.8 ± 2.6) d vs.(7.0 ± 1.3) d,t =0.679,P =0.006] was significantly shorter in laparoscopic group than that in open surgery group.In addition,the mean length of operation time [(77 ± 33) min vs.(55 ± 23) min,t =3.431,P ＜0.01] were longer,postoperative first passing flatus [(2.3 ± 1.2) d vs.(1.4 ±0.9) d,t =4.665,P ＜0.01] and oral intake [(2.3 ± 1.4) d vs.(1.2 ±0.6) d,t =4.517,P＜0.01] were later for acute appendicitis patients than for chronic appendicitis in laparoscopic group.Conclusions Laparoscopic appendectomy for acute appendicitis is a safe and effective procedure,though it might cause more postoperative complications such as intra-abdominal abscess and small intestinal obstruction in patients with acute appendicitis.

Objective This study was to investigate the relationship between the activities of thymidine phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD) and clinicopathological parameters in human colorectal cancer,and the relationship between TP and/or DPD activity in tumor tissue and efficiency of chemotherapy. MethodsSixty-eight patients undergoing surgery for primary colorectal cancer were enrolled including 40 patients receiving postoperative adjuvant chemotherapy with 5-FU plus leucovorin(de Gramont regimen). The activities of TP and DPD both in tumor tissue and in normal tissue were determined by enzyme-linked immunosorbent assay(ELISA). Results The TP activity was significantly higher in tumor than in normal tissues(P

Objective The purpose of this study is to investigate the factors associated with incisional surgical site infection (SSI) in colorectal cancer. Methods We retrospectively analyzed impacting factors of SSI including age, gender, BMI, diabetes mellitus, operation, albumin levels, hemoglobin levels, tumor staging, and length of stay post-operation in 327 colorectal patients from 2001 to 2005. Results The incidences of SSI and fat liquefaction were 2. 4%(8/327) and 12. 2%(40/327) respectively. The incidences of SSI in patients with obesity and diabetes mellitus increased significantly (16. 8% vs. 10. 0% ,28. 6% vs. 13. 7%). The length of stay in patients with SSI prolonged significantly (29.0 d vs. 15.8 d). Conclusion Obesity and diabetes mellitus are the most important factors associated with SSI in colorectal cancer patients.

Objective To study the the causes, management and preventive measures for complications of holmium laser ureterolithotripsy. Methods Three hundred and seven cases of uteteral calculi from Jan. 2006 to Jan. 2010 were reported (203 men and 104 women, age ranged from 18-83 years,mean age 51.6 years). One hundred thirty-three patients had calculi in the lower ureter,94 in the middle part and 80in the upper ureter. Results The overall comminution rate was 89.9% (276/307 cases). sixteen cases (5.2%) were followed by ESWL due to the shift of the stones to the renal pelvis. The operation failed in 9 cases(2.9%), 3 cases(1%) had perforation,and recoveried after open operation. Deep infection was found in 3(1%)cases,which recoveried after anti-infective therapy. Conclusions Holmium laser ureterolithotripsy is an effective method for treating ureteral calculi, with advantage of high efficiacy,safety and minimal invasion. To master the operating induction, to raise operating technique and to take correct measure could reduce complications effectually.

Objective To compare the therapeutic efficiency of laparoscopic and open radical colorectal surgery in the treatment of colorectal carcinoma. Methods Clinical data of 77 cases undergoing laparoscopic colorectal surgery from September 2004 to October 2007 were compared with 90 patients treated by open surgery. Results Mean operating time was longer in the laparoseopic group than that in the open group [248 minutes vs. 225 minutes (t = -2. 11 ,P =0. 036)], blood loss was less in laparoscopic group [210 ml vs. 315 ml (t = 2. 82, P = 0. 005)]. Laparoscopic surgery was associated with lower rate of analgesia use [48% vs. 80% (x2 = 18. 69 ,P < 0. 01)], earlier recovery of bowel function [2. 9 days vs. 4. 3 days(t =5.59,P <0. 01)]and shorter hospital stay [12. 5 days vs. 15.5 days (t =2. 32,P=0. 039)]compared with open surgery. The number of removed lymph nodes [14. 2 vs. 15.3 (t = 1.04, P = 0. 3)]and length of reseeted bowel [18. 9 cm vs. 20. 0 cm, (t = 0. 88,P = 0. 383)]were not different between the two groups. The mean follow-up time of the two groups were 28 months, local recurrence rate, metachronous metastases rate and 3-year cumulative survival rate were not statistically different between the two groups. Conclusion Laparoscopic surgery is as effective as conventional open surgery in the treatment of colorectal carcinoma.

Objective:To explore the effect of independent E purchasing skill training on social function rehabilitation of long-term inpatients with schizophrenia.Methods:A total of 42 inpatients with schizophrenia was divided into control group (22 cases) and experimental group (20 cases) by the random number table method. The control group was treated with traditional routine nursing and drug therapy, while the experimental group was treated with independent E purchasing skills training and drug therapy. The curative effect was evaluated by the Positive and Negative Syndrome Scale (PANSS), General Self-Efficacy Scale (GSES), Scale of Social function in Psychosis Inpatients (SSPI) before the intervention and at the end of the 12th week of intervention.Results:After 12 weeks intervention, the total score of PANSS in the experimental group was (44.60 ± 5.68), of which the positive symptom was (8.50 ± 1.47), the negative symptom was (11.90 ± 2.79) and the general psychopathology was (24.05 ± 3.02). In the control group, the scores of each type were (58.95 ± 9.62), (10.36 ± 3.67), (18.00 ± 4.67) and (30.59 ± 5.13). The difference between the two groups were statistically significant ( t values were -5.810- - 2.119, P<0.05). After 12 weeks intervention, the score of GSES in experimental group was (3.45 ± 0.48) and in control group (2.29± 0.69), the difference was statistically significant ( t value was 6.256, P<0.05). After 12 weeks intervention, the total score of SSPI was (38.90 ± 2.72), the score of the subjects' ability of daily living was (10.95 ± 1.19), the mobility and communication (15.45 ± 1.57), social activity skills (12.00 ± 1.34) in the experimental group. The scores of each type were (25.32 ± 6.36), (8.36 ± 1.59), (9.95 ± 2.75) and (7.00 ± 2.56) in the control group, the differences were statistically significant ( t values were 5.918-8.513, P<0.05). Conclusions:Independent E-purchasing skills training can improve the mental symptoms of long-term inpatients with schizophrenia, improve the self-efficacy and social function of inpatients with schizophrenia, and promote the rehabilitation of social function.
