ABSTRACT
Objective:To investigate the effects of repetitive transcranial magnetic stimulation (rTMS) on behavioral and psychological symptoms and quality of life in patients with mild to moderate Alzheimer disease (AD).Methods:Forty mild and moderate patients who met the diagnostic criteria of AD in the tenth edition of the International Classification of Diseases from May 2017 to December 2018 in the Seventh People′s Hospital of Wenzhou City were selected and divided into the control group (20 cases) and the rTMS group (20 cases) according to random number list. The control group was treated with basic treatment while the rTMS group was treated with rTMS on the basis of the basic treatment. The scores of AD assessment scale-cognitive section (ADAS-cog), mini mental state examination (MMSE), neuropsychiatric inventory (NPI), activity daily living (ADL), and quality of life in AD (QOL-AD) were observed and compared between the two groups before and after treatment.Results:There were no significant differences in ADAS-cog, MMSE, NPI, ADL, and QOL-AD scores between the rTMS group and the control group before treatment ( P>0.05). After treatment, the MMSE, ADL, and QOL-AD scores of the rTMS group were significantly higher than those of the control group: (22.80 ± 3.83) scores vs.(20.30 ± 5.49) scores, (63.05 ± 17.24) scores vs. (54.15 ± 9.20) scpres, (37.55 ± 7.94) scores vs. (31.00 ± 11.45) scores; the ADAS-cog and NPI scores were significantly lower: (18.45 ± 4.16) scores vs.(22.15 ± 5.01) scores, (57.2 ± 16.25) scores vs. (72.65 ± 39.37) scores, (27.15 ± 7.53) scores vs. (34.65 ± 14.91) scores, and there were significantly differences ( P<0.05). At the same time, the MMSE, ADL, and QOL-AD scores of the rTMS group were significantly higher than those before treatment, the ADAS-cog and NPI scores were significantly lower, and the difference was statistically significant ( P<0.05). Conclusions:rTMS can effectively improve the behavioral and psychological symptoms of patients with mild to moderate AD and significantly improve the quality of life.
ABSTRACT
Objective@#To understand the characteristics of HIV/AIDS epidemic in Guangxi Zhuang Autonomous Region (Guangxi) with a purpose to accurately provide scientific basis for prevention and control measures, 2010-2017.@*Methods@#Data were retrieved from case reporting cards of Guangxi during 2010 to 2017 through National HIV/AIDS Comprehensive Response Information Management System. Data was analyzed using epidemiological methods such number of cases, proportion and rate. χ2 test was used for statistical analysis.@*Results@#The HIV positive rate was 12.53 per ten thousand (85 182/67 959 000) in Guangxi during 2010 to 2017. The number of newly diagnosed HIV/AIDS cases and the number of death yearly respectively increased by 22.34%(2 602/11 648) and 32.83% (952/2 900) in 2011 compared with 2010, and both showed a six-year continuous downward trend (the number of newly diagnosed cases respectively 12 229 cases, 10 877 cases, 9 460 cases, 9 190 cases, 8 848 cases, 8 680 cases, and the number of death respectively 3 888 cases, 3 316 cases, 2 914 cases, 2 717 cases, 2 595 cases, 2 600 cases) from 2012 to 2017. But proportion of late discovery remained above 50.00% (50.53%-57.06%) for eight-years continuously. The ratio of male and female was 2.47 ∶ 1 (60 639/24 543). The ratio of males and females aged 50 and over was 2.71∶1 (28 654/10 557). Proportion of the cases in 25-49 years old group and 50 years old group accounting for 47.40%(40 377/85 182) and 46.03% (39 211/85 182) respectively. The occupation was farmers accounting for 68.40% (58 262/85 182), housekeeping, housework and unemployment accounting for 11.21% (9 546/85 182), student accounting for 0.86% (729/85 182). Heterosexual transmission accounted for 90.60% (77 171/85 182, homosexual transmission accounted for 3.13% (2 669/85 182), injection drug use transmission accounted for 4.60%(3 924/85 182) and mother-to-child transmission accounted for 0.73% (619/85 182).@*Conclusions@#The number of newly diagnosed cases and the number of death yearly showed a continuous downtrend for six-years from 2012 to 2017. However, proportion of late discovery remained above 50.00% for eight-years. The major route of infection was heterosexual transmission. With the change of HIV/AIDS newly epidemic mode in Guangxi, there are many new challenges for HIV/AIDS prevention and control work. Strategy of targeted intervention modes should be innovated for a new breakthrough.
ABSTRACT
Objective To investigate the expressions of CD133 and CD44 and their prognostic significance in gastrointestinal stromal tumors (GIST).Methods Streptavidin perosidase (SP) method of immunohistochemistry was used to detect expressions of CD133 and CD44 proteins in 42 cases of GIST, and the relationship between their expressions and tumor size, mitotic count were analyzed by univariate and multivariate factor analyses.Results The expressions of CD133 and CD44 proteins in GIST were 21.4％ (9/42) and 78.6％ (33/42), respectively.The expressions of CD133 and CD44 proteins were significantly correlated with tumor size and mitotic count (P ＜ 0.05).Univariate factor analysis showed that the overall survival of GIST patients with positive CD133 protein (23.2 months) was shorter than that of patients with negative CD133 protein(63.1 months) (P ＜ 0.05).The overall survival of GIST patients with negative CD44 protein (23.2 months) was shorter than that of patients with positive CD44 protein (63.3 months) (P ＜ 0.05).Multivariate factor analysis showed that tumor size, mitotic count and CD44 protein were independent prognostic indicators for survival time after operation.Conclusions The positive expressions of CD133 and CD44 proteins might be the prognostic factors of GIST patients.
ABSTRACT
Objective To study the relationship between serum carbohydrate antigen 19-9 (CA19-9) and blood glucose level in patients with type 2 diabetes (T2DM).Methods Totally 784 T2DM patients and 197 healthy controls were enrolled in this study.Age,duration,body mass index (BMI),systolic blood pressure (SBP),diastolic blood pressure (DBP),levels of fasting blood glucose (FBG),postprandial blood glucose (PBG),hemoglobin A1c (HbA1c),total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C),blood uric acid,C peptide and CA 19-9 were recorded.Patients were divided into different groups according to the levels of HbA1 c and CA 19-9.The relationship between CA19-9 and influencing factors was analyzed.Results CA19-9 level was increased in T2DM patients compared with healthy controls [(22.08±14.94) U/mlvs.(10.24±6.31) U/ml,t=12.10,P＜0.001].The levels of SBP,DBP,FBG,PBG,C peptide,TC,TG,LDL and UA were higher and HDL C level was lower in T2DM patients than in healthy controls (all P＜0.05).The levels of FBG,PBG and CA19-9 were increased along with the increase of HbA1c level in T2MD patients with HbA1c level under 6.5％,T2MD patients with HbA1c level from 6.5％ to 7.5％,T2MD patients with HbA1c level over 7.5％ [FBG:(6.36±3.70) mmol/L,(9.01±4.01) mmol/L,(11.96±4.73) mmol/L;PBG:(9.69±3.21) mmol/L,(12.18±5.54) mmol/L,(15.27±5.08) mmol/L; CA19 9 (14.33±11.72) U/ml,(18.76±14.39) U/ml,(25.96±17.52) U/ml,respectively,all P＜0.05].The levels of FBG,HbA1c and pancreatic cancer incidence were higher in patients with elevated CA19-9 than with normal CA19-9 [(11.71±5.48)mmol/L vs.(9.78±4.38)mmol/L,(7.49±4.12)％ vs.(6.33±3.70)％,0％ vs.7.8％,t=-3.51,2.55,x2=83.58,allP＜0.05].Pearson correlation analysis showed that CA19-9 level was positively correlated with the levels of HbA 1 c and FBG in T2DM patients (r=0.281,0.134,both P＜0.05).Multiple Logistic regression analysis showed that the levels of FBG and HbA1c were correlated with the increase of CA19 9 in T2DM patients(OR=0.801,0.947,P=0.019,0.026).Conclusions Serum CA19-9 level is significantly increased in T2DM patients compared with the healthy people.Serum CA19-9 level is correlated with blood glucose control.
ABSTRACT
ObjectiveTo investigate the relationship of lymphotoxin β receptor (LTβR) and classical nuclear factor-κB (NF-κB) activation pathway in the pathogenesis and progress of cystitis and bladder cancer.MethodsThe LTβR and P65 mRNA expression were detected by Real-time quantitative PCR in 108 cases of fresh bladder tissue specimens (75 cases of bladder cancer,10 cases of inflammation and 23 normal bladder mucosa cases grouped by the tissue classification ),and protein expression were analyzed by immunohistochemistry assay in 118 cases of paraffin-embedded biopsy specimens (73 cases of bladder cancer,30 cases of cysitis and 15 normal bladder mucosa cases).The correlation analysis between the expressions of LTβR and P65 with clinical pathological data was then performed.Differences between LTβR and P65 mRNA and protein expression level were compared in different groups of bladder tissues using Kruskal-Wallis H test and the Chi-square test.Results( 1 )The mRNA expressions of LTβR and NF-κB/P65were higher in bladder cancer than those in normal group ( LTβR:29.4 ( 14.2 - 46.7 ) × 10 - 3/1.2 ( 0.3 -7.0) ×10-3,Z=-5.508; P65:9.7 (2.7 -21.1) ×10-3/1.0(0.8 ～1.8) ×10-3,Z=-5.030,P＜0.05 ).There were significantly differences between bladder cancer with different histological grades ( LTβR:18.2(2.1-31.3) × 10-3/ 28.4(16.6-36.2) × 10-3/47.9(34.3 -70.5) ×10-3,x2K-W=20.378;P65:4.9(1.3 - 12.0) × 10-3/7.4(3.0-21.9) × 10-3/17.0(10.0 ～28.3)× 10-3 ,x2K-W2 =15.219,P all ＜0.05) and lymph node metastasis (LTβR:27.2(9.7-40.1) ×10-3/39.4(26.7 -52.6) ×10-3,Z=-2.552; P65:7.4(2.3-15.6) ×10-3/13.4(6.7-23.3) ×10-3,Z=-2.026,P＜0.05).(2)The positive rates of LTβR and phosphorylated P65 ( p-P65 ) protein in cancer were higber than those of normal group (LTβR:69.8％/13.3％,x2 =16.600 ; p-P65:56.2％/6.7％,x2 =12.220,P ＜ 0.05 ).Upregulation of LTβR and p-P65 were associated with the histological grade (LTβR:56.3％/70.0％/90.4％,x2 =7.055; p-P65:40.6％ /60.0％/76.2％,x2 =6.679,P ＜0.05) and with lymph node metastasis (LTβR:58.3％/92.0％,x2 =8.849; p-P65:52.1％/64.0％,x2 =5.088,P ＜0.05).(3)There was a positive correlation between LTβR and P65 expression ( mRNA:r =0.654,P ＜ 0.05,protein:r =0.399,P ＜ 0.05 )in the bladder cancer and cystitis (r =0.521,P＜0.05).ConclusionsThe activation of LTβR and P65 was associated with progression and metastasis of bladder cancer.The activation of classical NF-κB pathway by LTβR may be achieved by P65.
ABSTRACT
Objective To investigate the effects and mechanism of Cordyceps sinensis on transplant arteriosclerosis in a rat model Methods Brown Norway aortic allografts were transplanted into Lewis recipient rats,and the recipient rats were randomly divided into four groups:group A,isograft control group,Lewis-Lewis (n =10); group B,allograft control group,BN-Lewis (n =10); groups C and D,allograft experimental groups,BN-Lewis (n =10).Rats were given normal saline via intragastric injection,once every day for 60 days in groups A and group B,and received different doses (1.5 and 3 g·kg-1 ·d 1) of Cordyceps sinensis in groups C and group D respectively.Grafts were harvested on the day 60 after transplantation. Intimal thickness was detected by HE staining.Protein was extracted from the abdominal aortas for Western blotting.Cellular localization was assessed by histology and immunohistochemistry.The serum was analyzed by an enzyme-linked immunosorbent assay (ELISA). Results Transplanted arteries were normal in group A.Transplanted arteries in group A had allograft vasculopathy,and intimal thickness was significantly increased.Transplanted arteries in allograft experimental groups had endometritis changes,and intimal thickness was significantly decreased as compared with that in group B (P ＜ 0.05).Immunohistochemistry and Western blotting revealed that the expression levels of VEGF and PDGF-BB proteins in group A were significantly higher than in group B,and those in groups C and D were significantly reduced as compared with group B (P＜0.05).ELISA showed that serum VEGF and PDGF BB concentrations in group B were significantly increased as compared with group A (P＜0.05).Serum VEGF and PDGF-BB concentrations were significantly reduced in groups C and D as compared with group B (P＜0.05).Conclusion Cordyceps sinensis could significantly inhibit the intimal hyperplasia,and delayed transplant arteriosclerosis caused by chronic rejection,which may be related to the down-regulated expression of VEGF and PDGF-BB.
ABSTRACT
Objective To evaluate the application value of combined detection of PCA3 and PSA mRNA in peripheral blood of patients with prostate cancer(PCa) for evaluation of mien)metastasis. Methods PCA3 and PSA mRNA were detected by duplex real time quantitative RT-PCR in a total of 49 PCa and 71 benign protatic hyperplasia (BPH) patients' peripheral blood. The diagnostic value was analyzed by receiver operative characteristic(ROC) curve. Results The levels of PCA3 mRNA in PCa patients were significantly higher than those in BPH patients [2 362( <30-7 421 ) copies/ml vs <30 copies/M, Z = -6. 66, P < 0. 01 ], and the same to PSA mRNA [3 425 ( 908-36 639 ) copies/ml vs < 200 copies/ml, Z = - 6. 40, P<0. 01 ]. The positive rate of PCA3 and PSA mRNA in peripheral blood was positively correlated with clinical stage[clinical stage B: 30.0% (3/10), C: 60.0% (9/15) and 86.7% (13/15), D: 91.7% (22/24) and 91.7% (22/24) ,Chi-square = 13. 534 and 16. 541, P <0. 01, respectively]. Meanwhile, the positive rate of PCA3 mRNA and PSA mRNA was also increased with the increase of Gleason score[ Gleason score of 2 to 4 : 20.0% (1/5) and 40. 0% (2/5) ;5 to 7 : 66.7% (12/18) and 72. 2% ( 13/18 ) ;8 to 10 : 84. 6% (22/26) and 92.3% ( 24/26 ) ;Chi-square = 8. 895 and 8. 015, P < 0. 05, respectively ]. ROC analysis showed that the sensitivities for PCA3 and PSA mRNA were 69. 4% (34/49) and 81.7% (40/49) and the specificities was 90. 1% (64/71) and 77.5% (55/71), respectively, when the cut-off value was 846 copies/ml for PCA3 mRNA and 280 copies/ml for PSA mRNA. Meanwhile, the sensitivity can reach to 85.7% (42/49) when the detection of PCA3 and PSA mRNA were combined. However, the specificity was decreased to 76. 1% (54/71). For the diagnosis of PCa micrometastasis, the sensitivity and specificity for PCA3 mRNA was 90.9% (20/22) and 84.7% (11/13), respectively. Conclusions PCA3 and PSA mRNA in peripheral blood are useful markers for PCa diagnosis. Simultaneous detection for PCA3 and PSA mRNA is more helpful for PCa diagnosis. Meanwhile, detection of PCA3 mRNA is a useful marker for diagnosing PCa micrometastasis.
ABSTRACT
n be used as a potential marker in the diagnosis of PCa. However, it can not be used as an index to monitor tumor progression or prognosis in PCa patients.
ABSTRACT
Objective To explore the Clinicopathological characteristics of patients with primary adenosquamous and squamous carcinoma of stomach. Methods The clinical data of 12 cases of primary squamous and adenosquamous carcinoma of the stomach were reviewed retrospectively, and the immunohistochemical staining of CK17 and CKI8 protein were performed in primary gastric adenosquamous carcinoma. Results Primary adenosquamous and squamous carcinoma of the stomach accounted for 0.28% of all the 4352 patients with gastric cancer during the same period. Of the 12 patients, 10 were adenosquamous carcinoma and other two were squamous carcinoma. There were 10 males and 2 females in this group, with their mean age being 65 years. The main clinical presentation included epigastric pain and discomfort, followed by hematemesis and melena. The definite diagnosis rate was 33% (4/12) by gastroscopy and biopsy before operation. The tumors were less than 5 cm in diameter in 3 patients, and more than 5 cm in 9 patients. The surgical procedure was radical resection in 8 patients and palliative resection in 4 patients. There were 1 case of stage Ⅰ, 5 cases of stage Ⅲ, 6 cases of stage Ⅳ. 10 patients died of tumor recurrence and metastasis within 2 years after operation, one died of other unrelated disease, and one was alive for more than 5 months. The component of both adenosquamous and squamous carcinoma were more than 30% in 4 patients with adenosquamous carcinoma who underwent palliative resection and died within 6 months after operation. Conclusions Primary adenosquamous and squamous carcinoma of the stomach were rare, and had specific clinicopathological characteristics. Having both biological behaviours of adenocarcinoma and squamous carcinoma may lead to poor prognosis in adenosquamous carcinoma of stomach.
ABSTRACT
Objective To explore hypermethylation of RARβ2, GSTP1 and DAPK gene in prostate cancer tissues, and to explore its correlation with clinicopathological features of prostate cancer and its diagnostic value. Methods Hypermethylation of RARe2, GSTP1 and DAPK gene was detected by nested methylation-specific PCR (NMSP) in 57 prostate cancer (PCa) tissues and 35 benign prostate hyperplasia (BPH) tissues. The correlation between hypermethylation and clinicopathological features of prostate cancer and its diagnostic value were analyzed. Results The hypermethylation frequencies of RARβ2, GSTP1 and DAPK gene in PCa were significantly higher than those in BPH (RARβ2: 52.6% vs. 0% GSTP1: 61.4% vs. 2.9%;DAPK: 43.9% vs. 8.6%;all P<0.01). The methylation rate of RARβ2 gene was directly correlated with distinct Gleason scores and clinical stage (4～7 score vs. 8～10 score: 34.8% vs. 64.7%;stage B, C vs. stage D: 37.0% vs. 66.7%;x2=4.927 and 5.004, P=0.026 and 0.025). The methylation rate of GSTP1 gene was significantly different in patients with different Gleason scores (4～7 score vs. 8～10 score: 43.5% vs. 73.5%;x2 =11.530, P=0.001), but had no difference in patients with distinct clinical stage (stage B, C vs. stage D: 51.9% vs. 70.0%;x2=1.975, P=0.16) . There was no difference in DAPK gene methylation rate among patients with different Gleason scores and distinct clinical stage (4 ～7 score vs. 8～10 score: 39.1% vs. 50.0%;stage B, C vs. stage D: 33.3% vs. 53.3%;x2= 1.290 and 2.309, both P～0.05). GSTP1 gene showed the highest sensitivity of 61.4% (35/57)with specificity of 97.1%(34/35), while RARβ2 gene had the highest specificity of 100% (35/35) with the sensitivity of 52.6% (30/57). The sensitivity and specificity of DAPK gene were 43.9% and 91.4% (25/57 and 32/35), respeetively. When the hypermethylation of RARβ2, GSTP1 and DAPK gene were detected together, the diagnostic sensitivity was increased, but the specificity was decreased. Conclusions The aberrant methylation of RARβ2, GSTP1 and DAPK gene is correlated with tumorigenesis and progression of prostate cancer, which may be used as an effective diagnostic marker for prostate cancer.

Methods In this study.samples of 43 MALT lymphoma were studied histologically and divided into monomorphic histology group and polymorphic histology group according to their cellular features.The expressions of FOXP1 and NF-κB in gastric MALT lymphoma were evaluated immunohistochemically by two-step method of Envision,and the clinicopathological features and prognosis were analyzed retrospectively.Results The nuclear expressions of FOXP1 in 43 cases with gastric MALT lymphoma were 44%(19 of 43),including strong immunoreactivity in 7 cases and moderate immunoreactivity in 12 cases.There were 4 cases with positive immunoreactivity in moninorphic histology group and 15 cases in polymorphie histology group,and the difference was statistically significant(15%vs.88%,P＜0.01).All the postoperative recurrent cases were strongly positive with FOXP1 stain,and it was closely with FOXP1 expression(P＜0.01).The median survival time(26 months)in polymorphic histology group was significantly shorter than that(123 months)in monmorphic histology group(P＜0.01),and the median survival time was significantly longer in negative FOXP1 expression group than that in moderate FOXP1 expression group and in strong FOXP1 expression group(115 vs.55 vs.12 months)(P＜0.05).similarly,the median survival time in nuclear factor kappa B(NF-κB)expression group was significantly shorter than that in negative NF-κB expression group(26 vs.131 months)(P＜0.01).The median survival time in stageⅠ(98 months)and stage Ⅱ(121 months)was significantly longer than that in stage Ⅱ E+Ⅳ(33 months)(P＜0.01).By multivariate COX regression analysis.FOXP1 nuclear expression and clinical stage were independently prognostic factom. Conclusion FOXP1 expression may be used as a biomarker for the assessment of malignant transformation to diffuse large B-cell lymphoma(DLBCL)and predicting prognosis.
ABSTRACT
ObjectiveTo investigate the finasteride application during the off-cycle of intermittent androgen blockade (IAB) in patients with advanced prostate cancer treated with IAB.MethodsEighty-seven patients with advanced prostate cancer were divided into two groups: forty-nine patients received IAB (group A), and thirty-eight patients underwent IAB and finasteride during the off-cycle of IAB (group B). The time of treatment cycle and the time to disease progression were compared between the two groups. ResultsThe patients in group A completed 89 treatment cycles and the mean cycle length was (12.8±5.4) months [treatment time and non-treatment time were (6.6±3.5) months and (7.1±4.8) months, respectively]. The patients in group B completed 85 cycles and the mean cycle length was (15.3±5.9) months [treatment time and non-treatment time were (6.9±3.2) months and (9.2v±3.9) months, respectively]. There was a significant difference between group A and B in the mean cycle length and the non-treatment time (P=0.0428,P=0.03).The 3-year progression rate was ( 34.8±3.5 )% in group A and ( 28.4±2.7)% in groups B ( P=0.035). ConclusionsThe application of finasteride during the off-cycle of IAB in patients with advanced prostate cancer treated with intermittent androgen blockade (IAB) can delay progression of advanced prostate cancer.
ABSTRACT
Objective To investigate the effect of liver function with portal vein occlusion (PVO) in various phases and the following restoration portal vein flow on intestinal mucosal cells. Methods Twenty-four healthy adults white Japanese rabbits were randomized into 1 control group and 2 experimental groups (according to portal vein clamping for 30 min and 45 min). Each experimental group's blood samples were collected from caval vein 1 h before operation, by the end of portal vein oc-cluded, 30 min, 60 rain after relief of portal vein blocking, then with restoration of portal vein flow for 2 h and rabbit guts were continuously cut to sections for HE, TUNEL staining and Bcl-2, Bax protein immunohistochemical staining to observe the injury of intestinal mucosa cell apoptosis and the relation-ship between the expressions of Bcl-2 and Bax. The levels of blood glutamate-pyruvate transaminase (ALT), glutamic oxalacetic transaminase (AST) were measured and compared. Results The levels of ALT, AST in the control group did not significantly change. Compared with control group, group B did not change significantly with PVO 30 rnin in liver enzyme and they were significantly increased after portal vein occlusion relief. The levels of ALT and AST were increased obviously at 45 min with PVO, then raised again. Down-regulation of Bcl-2 expression, up-regulation of Bax expression and the increased index of apoptotic cell were found in each experimental group. Conclusion It may be more safe with PVO for 30 min. But the following restoration portal vein flow will bring about ischemia-reperfusion injury that is mainly apoptosis in the small intestine. The index of apoptosis will be raised with time prolongation of PVO.

Results The expressions of DD3 mRNA and PSA mRNA, and DD3 mRNA/ PSA mRNA were significantly higher in PCa tissues than those in BPH tissues ( P 0.05 for all). The AUC-ROC of DD3 mRNA,PSA mRNA and DD3 mRNA/PSA mRNA were 0. 937 (95% CI,0. 879 -0. 995) , 0.755(95% CI,0.629 -0.880) and 0.839 (95%CI,0.738 -0.940),respectively. The sensitivity for DD3 mRNA,PSA mRNA and DD3 mRNA/PSA mRNA was 90. 5% ,81. 0% and 81. 0% , respectively, and the specificity was 85.0% ,62.0% and 66.7% at cutoff value of 1.4?105 copies/mg tissue,3.0?107 copies/ mg tissue and 5. 0?10-3,respectively. The sensitivity and specificity of simultaneous detection for DD3 mRNA and PSA mRNA were 100% and 85.0%. Conclusions Both DD3 mRNA and PSA mRNA expressions were significantly higher in PCa tissues than those in BPH tissues; and the quantitative detection of DD3 mRNA is more helpful for the diagnosis. The simultaneous detection of DD3 mRNA and PSA mRNA can improve the sensitivity in the diagnosis of PCa.
ABSTRACT
Objective To evaluate the efficacy of surgical retrieval of testicular spermatozoa,and to present the preliminary results of the retrieved testicular spermatozoa used in intracytoplasmic sperm injection (ICSI) for treatment of non obstructive azoospermic infertility. Methods Forty nine cases of non obstructive azoospermia underwent open testicular biopsy and diagnostic testicular sperm extraction (TESE).Those who had sperms in diagnostic TESE underwent ICSI at least 3 months later. Results Sperms were detected in diagnostic TESE in 12 cases (24.9%). The testicular volume,FSH level and testicular pathology did not accurately predict the presence or absence of sperm in testes.Seven (87.5%) of 8 cases had sperm in re TESE, which were used in their ICSI cycles,resulting in 3 clinical pregnancies. Conclusions The diagnostic TESE should be performed to determine the presence or absence of testicular spermatozoa in testicular failure before ICSI,and the surgically retrieved testicular spermatozoa can be adopted in ICSI for treatment of non obstructive azoospermic infertility.
