The phagocytic activity of ICR mice peritoneal macrophage on chiken RBC . In addittion, it was considerably Stimulated by using ip TGP at dose of 40mg/kg/d for 3d. The results suggested that TGP might possess the immunoregulatory effects in mice.

Objective To evaluate the feasibility of retroperitoneal laparoscopic adrenalectomy for large (≥6 cm in diameter) adrenal tumors. Methods Between June 2002 and June 2008,30 patients with large adrenal tumors underwent retroperitoneal laparoscopic adrenalectomy in our hospital. With the patients being placed in the lateral position at the uninjured side,a self-made balloon was used to dilate the retroperitoneal space. Afterwards,3 trocars were inserted via the costal margin at the posterior axillary line and the anterior axillary line,and 2 cm above the anterior superior iliac spine at the middle axillary line to remove the tumors. After resection of the tumor,an drainage tube was indwelled. Results Retroperitoneal laparoscopic surgery was performed successfully in the 30 cases without conversion to open surgery. The mean operation time was 100 min (range,65 to 185 min),and the mean blood loss was 80 ml (range,50 to 250 ml). Over a mean of 18.5-month follow-up (range,3 to 36 months) was achieved in the cases,during which no one had local recurrence. Conclusions Retroperitoneal laparoscopic adrenalectomy is feasible and safe for patients with large adrenal tumors as long as no contraindication of the surgery is found. The diameter of the tumor does not play a role when determining the surgery.

Objective To evaluate the semen quality of potential semen donors of college students and investigate their reproductive health status. Methods According to the screening procedure in the Basic Standard and the Technical Norms of Human Sperm Bank revised by Chinese Ministry of Health in 2003,all sperm samples of 355 potential donors were examined. Results 37 of 355 donors sperm(10.4%) were qualified to the normal standard revised by Chinese Ministry of Health;and the rest(89.6%) were abandoned,because the sperm numbers of 267 donors were not reached the identified semen standard of the human sperm bank in the first screen,26 donors(7.4%)were with abnormal health status,4 donors did not ejaculate and got samples,9 donors with normal semen quality did not take physical health examination,the normal shape percentage of 6 donors sperm was lower than 30% and the thawed revival percentage with(a+b) grade of 6 donors was lower than 60%.135 of 355 donors(38.0%) sperm quality were qualified to the male productive standard of WHO. Conclusion The results indicated that the sperm quality of undergraduate declines and the society should pay more attention to the reproductive health of college students.

Objective: To explore the value of body measurement indicators in screening for metabolic syndrome (MS), so as to provide the basis for early detection and prevention of MS. Methods: The individuals who were 18 years old or above and underwent physical examinations at a tertiary hospital of Xinjiang Uygur Autonomous Region were selected using the convenience sampling method. Demographic information, lifestyle, waist circumference (WC) and blood biochemical indicators were collected through questionnaire surveys, physical examinations and laboratory tests. The associations of WC, waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), body roundness index (BRI), abdominal volume index (AVI), lipid accumulation product (LAP) and visceral adiposity index (VAI) with MS were analyzed using a multivariable logistic regression model. The screening values of these body measurement indicators for MS were assessed by receiver operating characteristic (ROC) curves. Results: A total of 37 921 individuals were recruited, including 20 666 males (54.50%) and 17 255 females (45.50%), and had a median age of 41.00 (interquartile range, 20.00) years. There were 7 988 cases of MS, with a detection rate of 21.06%. Multivariable logistic regression analysis showed that WC, WHR, LAP and VAI were statistically associated with MS (all P<0.05), and the risk of MS increased with the levels of these indicators (all Ptrend<0.05), after adjusting for confounding factors (gender, age, lifestyle, etc.). The area under the ROC curve (AUC) of LAP for screening MS was the highest among single indicators, at 0.930 (95%CI: 0.927-0.933), and the optimal cut-off value was 43.13, Youden's index was 0.720, the sensitivity was 88.01%, and the specificity was 84.04%. The combined indicators of WC×VAI for screening MS had the highest AUC, which was 0.937 (95%CI: 0.935-0.939), and the optimal cut-off value was 0.17, Youden's index was 0.730, the sensitivity was 91.88%, and the specificity was 81.07%. The DeLong test showed that the AUC of WC×VAI for screening MS was higher than that of WC, WHR, LAP and VAI, respectively (all P<0.05). Conclusion The value of combining WC and VAI for screening MS is higher than other body measurement indicators.

Objective To analyze the clinical and pathological characteristics of thyroid nodules.Methods A retrospective analysis of the clinical data of 2843 Han patients with thyroid nodules from January 2009 to June 2011 in Henan province was performed.Results The most high-risk of thyroid nodule resided in the group aged 45-54.The main pathological manifestation was simple nodular goiter.The rate of preoperative misdiagnosis was 2.4％.22.1％ of the patients with thyroid nodules showed abnormal thyroid function,which was mainly as subclinical thyroid dysfunction.The positive rate of thyroid peroxidase antibody (TPOAb) in patients with thyroid nodule was 19.8％ while that of thyroid globulin antibody (TgAb) was 20.0％.Among all 2843 subjects,the prevalence of differentiated thyroid carcinoma (DTC) was 28.8％,and the incidence of DTC was accompanied by raised TSH levels.The prevalence of DTC exceeded 40％ in patients aged between 25 to 34 as well as more than 74 years old.The prevalence of DTC was up to 33.8％ in TgAb positive patients.There was no difference in TPOAb levels between DTC patients and non DTC patients (P =0.406),but the TgAb level in patients with DTC was significantly higher than that of non DTC patients (P =0.033).Conclusion Thyroid nodule patients aged 25-34 or older than 74 formed high-risk groups of DTC.The serum TSH level and TgAb level were positively correlated with the risk of DTC.

Objective To explore the effect of decoction of four-drug juice plus glutamine on nutritional support in the elderly critically ill patients. Methods One hundred and twenty-four elderly critical ill patients in The First Hospital of Jilin University from May 2010 to May 2012 were randomly divided into treatment group(n = 62)and control group(n = 62). Patients in both two groups were given enteral nutrition(EN)plus parenteral nutrition(PN)after the hemodynamics became stable. In addition,patients in control group were given routine EN + PN,while in treatment group was given decoction o four-drug juice + EN plus glutamine + PN. Prealbumin (PA),serum total protein( TP),transferrin( TF)and serum albumin( ALB)were detected before and after treatment of nutritional support. The informations including recovery of bowel sounds,the occurrence of complications,antibiotic use time and the duration of ICU stay were recorded. Results There were no significant differences between two groups in terms of nutrition indices before treatment(P > 0. 05). After treatment,the contents of pre albumin,transferrin,total serum protein,serum albumin in treatment group were( 145. 24 ± 6. 72)g/ L,(1. 93 ± 0. 98)g/ L,(79. 86 ± 10. 38)g/ L,(54. 91 ± 2. 91)g/ L respectively,better than those in control groups((139. 24 ± 38. 76),(1. 68 ± 0. 33),(74. 73 ± 7. 31),(49. 87 ± 2. 61)g/ L),and the differences were statistically significant( t = 3. 610,2. 929,4. 360,6. 767;P < 0. 05). The incidence of stress ulcer and double infection in treatment group were 42%(26 / 62),37%(23 / 62),significantly lower than the control group(59%(37 / 62),53%(33 / 62)),and the differences were statistically significant( χ2 = 5. 186, 5. 271,P < 0. 05). Antibiotic use time and the duration of ICU stay in treatment group were(8. 82 ± 0. 71)d and(16. 14 ± 3. 01)d,and reaching full eternal nutrition time was(6. 90 ± 1. 01)d,decreased less than that in control group((10. 21 ± 1. 30),(20. 67 ± 2. 29),(13. 91 ± 1. 51)d)and the differences were statistically significant(t = 8. 892,7. 786,3. 609,P < 0. 05). The average recovery time of bowel sounds and first anal exhaust time average in treatment group were(26. 8 ± 3. 6)h,(25. 4 ± 3. 2)h,lower than that in control group ((38. 4 ± 4. 8)h,(37. 6 ± 4. 9)h)and the differences were statistically significant( t = 3. 551,2. 516,P< 0. 05). Conclusion The application of decoction of four-drug juice plus glutamine on nutritional support of the elderly critically ill patients can reduce complications,shorten the duration of ICU,recover the intestinal function as soon as possible. Meanwhile,patients can transit to full eternal nutrition as soon as possible,then the cost of therapy is reduced and rehabilitation is quickly.

Objective:To evaluate the effects of several kinds of surface treatment methods on the bond strength of zirconia prosthesis,and to provide references for improving the bond strength of zirconia prosthesis.Methods:Sixty zirconia blocks(10 mm×10 mm×2 mm) were divided into 6 groups according to the surface treatment methods:sandblasting,silica coating,Z-PRIME Plus,sandblasting+Z-PRIME Plus,sandblasting+silica coating,and silica coating+Z-PRIME Plus groups.The zirconia-resin specimens were fabricated using ScotchbondTM Universal;shear bond test was performed to detect the shear bond strength after treated with water storage(37℃) for 24 h by universal mechanical testing mechine;the fracture types were observed by stereoscopic microscope.One fracture specimen was randomly chosen from each group,and the morphology of the specimen was examined under scanning electron microscope.Results:The shear bond strength of the specimen in Z-PRIME Plus group was higher than those in the other groups(P<0.05).The adhesive failure was predominantly observed in sandblasting,silica coating,sandblasting+silica coating and silica coating+Z-PRIME Plus groups.There were 4 cases of mixed failure in Z-PRIME Plus group and there were 8 cases of mixed failure in sandblasting+Z-PRIME group.No cohesive failure was observed in all the groups.The scanning electron microscope results showed that the fracture surface occurred on the resin-zirconia interface of the specimens in sandblasting group,Z-PRIME Plus group,and sandblasting+Z-PRIME Plus group.The silica-zirconia fracture of specimens occurred in silica coating group and silica coating+Z-PRIME Plus group.The silica-resin interface fracture of specimens partially occurred in sandblasting+silica coating group.Conclusion:The application of Z-PRIME Plus can significantly improve the bond strength between zirconia and resin.

Aim To evaluate the effect of expression inhibition of spermine oxidase(SMO)on the actitumor activity of polyamine analogue CPENSpm (N~1-cyclopropylmethyl-N~(11)-ethylnorspermine).Methods siRNA technique was used to inhibit expression of SMO in human lung cancer line A549.QT-RT-PCR and enzyme activity assay was performed to determine the expression level of SMO.The cell proliferation was detected by MTT assay.The apoptosis of A549 cells were evaluated by DNA degradation and Sub-G_1/flow cytometry assay.Results The A549 cell line with silenced SMO expression was successfully obtained.Basic SMO mRNA and enzyme activity levels in the SMO-siRNA plasmid transfected cells were 0.53% and 14% lower than that in the control cells respectively. Treating A549 control cells by 10 μmol·L~(-1) CPENSpm for 24 hours resulted in a 10-folds up-regulation of SMO in mRNA level and 20-fold increase in enzyme activity,but this drug-induced SMO expression was obviously prevented in SMO-siRNA plasmid transfected cells.MTT assay demonstrated that SMO expression inhibition decreased the sensitivity of A549 cells to CPENSpm exposure(0～20 μmol·L~(-1)).DNA degradation and sub-G_1 assay proved a deceased ability of CPENSpm to induce apoptosis in SMO-siRNA plasmid transfected cells.Conclusion Up-regulation of SMO by CPENSpm is possibly one of the molecular basics for its antitumor activity.
