OBJECTIVETo evaluate the clinical effectiveness of transurethral seminal vesiculoscopy (TUSV) combined with finasteride in the treatment of recurrent hemospermia.

METHODSThis study included 32 patients with recurrent hematospermia, with the disease course of 3 months to 4 years. After administration of finasteride at 5 mg/d for 2 weeks, the patients underwent TUSV for both exploration of the causes and treatment, followed by medication with finasteride at the same dose for another 2 weeks. Postoperative follow-up was conducted for observation of the outcomes and complications.

RESULTSTUSV was successfully accomplished in all the 32 cases, which revealed 16 cases of seminal vesiculitis, 10 seminal calculi, 1 seminal vesicle cyst, 2 seminal vesicle polyps, and 3 seminal vesicle abscess. The operative time was 20 to 51 (31.0 +/- 5.2) minutes. Postoperative complications included 1 case of acute epididymitis and 3 cases of breast discomfort within the first 4 weeks. No incontinence, urethral stricture, rectal injury, retrograde ejaculation, and sexual dysfunction occurred postoperatively. All the patients but 1 were followed up for 6 months to 2 years. Twenty-nine of the cases were cured, and 2 experienced recurrence.

CONCLUSIONTransurethral seminal vesiculoscopy combined with finasteride is safe and effective for the treatment of recurrent hemospermia.

OBJECTIVETo explore the role of nuclear factor-kappaB (NF-kappaB) in the protective effects of propofol against liver ischemia-reperfusion (IR) injury.

METHODSForty male rats were randomized into 4 equal groups, namely the sham operation (N) group, IR group with hepatic IR injury (induced by ischemia of the left, right and median hepatic lobes for 1 h followed by reperfusion for 2 h), propofol (P) group with sham operation and propofol perfusion at 10 mg kg(-1) h(-1), and propofol treatment (PIR) group with IR injury and propofol perfusion. RT-PCR was used to detect the transcription level of NF-kappaB, and Western blotting was used for assaying NF-kappaB protein expression in the liver.

RESULTSCompared with either the N or the P group, the IR group showed obvious swelling, fatty degeneration and scatter focal necrosis of the hepatocytes as well as mild congestion in the hepatic sinusoid, with significantly increased plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels and NF-kappaB expressions at both mRNA and protein levels (P<0.05). In the PIR group, the histopathological changes of the liver was lessened as compared with the IR group, and ALT and AST elevation was significantly inhibited (P<0.05) as was the protein expression of NF-kappaB (P<0.05), but NF-kappaB transcription level was further enhanced (P<0.05).

CONCLUSIONPropofol can protect the liver from IR injury possibly by inhibiting NF-kappaB expression.

Objective:To explore whether sleep quality suffers in patients with mild Alzheimer's disease(AD)and mild cognitive impairment(MCI), and to further investigate the correlation between sleep disorders and cognitive function in these patients.Methods:In this study, 30 mild AD patients, 39 MCI patients and 43 demographically matched healthy controls were enrolled.Sleep quality was assessed by the Pittsburgh sleep quality index(PSQI), and cognitive function was assessed by the mini-mental state examination(MMSE), the Montreal cognitive assessment(MoCA)and a set of neuropsychological scales.The correlation of sleep quality with cognitive function was analyzed for the three groups.Results:Differences were significant in sleep time score[0.0(1.0), 1.0(2.0) vs.1.0(1.0), F=8.18, P=0.02]and daytime function score[1.0(1.0), 1.0(1.0) vs.0.0(1.0), F=8.73, P=0.01]between mild AD, MCI and health control groups.Spearman correlation analysis suggested that scores of sleep disorders were negatively correlated with DSB( r=-0.43, P=0.02)and scores of daytime function were positively correlated with ADL( r=0.39, P=0.03)in patients with mild AD.In addition, scores of sleep quality were negatively correlated with the DSB score( r=-0.40, P=0.01), scores of sleep disorders were positively correlated with ADL( r=0.45, P<0.01), scores of daytime function were negatively correlated with DSF( r=-0.42, P=0.01), DSB( r=-0.62, P<0.01)and VFT-S( r=-0.33, P=0.04), and the total PSQI score was negatively correlated with DSF( r=-0.45, P=0.01)and DSB( r=-0.44, P=0.01)in the MCI group. Conclusions:Patients with mild AD and MCI have longer sleep time and impaired daytime function than healthy people, and sleep quality is correlated with memory, attention and daily living ability in patients with mild AD and MCI.

Objective To evaluate the CT features and implications of the pericardial sinuses and recesses effusion by combining the sectional cadavers and 16 mttlti-slice CT(MSCT)reformation.Methods The anatomy and communication of the pericardial sinuses and recesses on the axial,coronal and saggital sectional cadavers(respectively 1 case),and the morphologic features on MSCT reformatted images in 104 patients were observed,The detection rate of effusion was analyzed.Results The sectional cadavers and CT images showed that the pericardia] sinuses and recesses were formed by the reflections of the pericardium on the root of the great vessels.The detection rate of the sinuses and recesses was lower in small effusion than in moderate and large effusion(P

Objective To provide reference for clinical rational drug use,the adverse drug reaction(ADR)automatic monitoring system was used to monitor ADR in patients treated with first-line anti-tuberculosis drugs.Methods A total of 1 147 tuberculosis patients hospitalized in the infection department of our hospital from 2019 to 2022 were selected to monitor the occurrence of ADR during the hospitalization.Univariate and multivariate analysis were used to study the risk factors affecting the incidence of ADR.Results After systematic screening and pharmacist review,a total of 598 cases of ADR related to first-line anti-tuberculosis drugs were found,with an incidence of 52.14％.ADR mainly affects the endocrine system,digestive system,and hepatobiliary system.The incidence of ADR in oral isoniazid is higher than that in intravenous drip and nebulization routes.The results of multivariate regression analysis showed that women and a history of hepatitis were independent risk factors for the occurrence of ADR(all P＜0.05).Conclusion The incidence of ADR with anti-tuberculosis drugs is high.Women and patients with a history of hepatitis are high-risk groups for adverse drug reactions to anti-tuberculosis drugs.In clinical,safer drugs should be selected for such patients,and the occurrence of ADR should be closely monitored to reduce the impact of ADR on the treatment process.

OBJECTIVETo explore the indication and optimum time for treating myelodysplastic syndrome (MDS) by allogeneic hematopoietic stem cell transplantation (allo-HSCT) with HLA identical sibling grafts.

METHODSFrom June 1997 to Sep. 2004, a total of 30 patients with MDS were treated with allo-HSCT from HLA-identical sibling donors in our institute. On HSCT, 4 patients had refractory anemia (RA) , 2 RA with ringed sideroblasts (RARS) , 7 RA with excess blasts(RAEB) , 14 RAEB in transformation (RAEB-t) , 3 already progressed to secondary AML. For IPSS system, 6 patients were in intermediate- I risk group, 11 in intermediate- li risk group, and 13 in high risk group. The modified BU/CY conditioning regimen was used. Four patients received bone marrow transplantation (BMT), 8 received peripheral blood stem cell transplantation (PBSCT) , and 18 received BMT + PBSCT.

RESULTSThe 3-year expected overall survival (OS) was 63.61%, 3-year expected disease-free survival ( DFS) 61.41%, and relapse rate 5.26%; OS for RA/ RAS, RAEB and RAEB-t/AML subgroup was 83.33%, 34.29% and 66.67% , respectively, and all had no statistic difference among them. OS for IPSS-intermediate and high risk subgroup was 64.7% , and 69.0% respectively, also had no statistic difference. 3-year expected OS in no aGVHD,grade I - II aGVHD and grade III - IV aGVHD group was 57.75% , 100% and 0% , respectively (P = 0.009). Pre-HSCT chemotherapy, disease subtype and cGVHD all had no correlation with LFS or OS (P > 0.05).

CONCLUSIONFor young MDS patients having HLA-identical sibling donors, HSCT should be the first line therapy and performed as soon as possible.

Introduction:The 2010 targets of the China Hepatitis B Prevention Programme were a prevalence of hepatitis B surface antigen (HBsAg) less than 1.0% for children less than five years old and less than 6.0% for the total population. This survey assessed the prevalence of Hepatitis B infection in Lianyungang, Jiangsu province, China in 2009–2010.Methods:Multistage sampling was used with 2372 subjects among 17 selected villages. Blood specimen collection and testing by enzyme-linked immunosorbnet assay (ELISA) were completed using the following markers for hepatitis infection: HBsAg and antibody to HBsAg (anti-HBs); hepatitis B e antigen (HBeAg) and antibody to HBeAg (anti-HBe); and hepatitis B core antibody (total anti-HBc). The data were analysed with Epi Info, version 3.3.2.Results:The prevalence of HBsAg was 2.4% (95% Confidence Interval [CI]: 1.8–3.0; Adjusted Prevalence [AP] 2.9%); anti-HBs prevalence was 51.1% (95% CI: 49.1–53.1; AP 49.2%) and total anti-HBc prevalence was 41.7% (95% CI: 39.8–43.7; AP 45.5%). The prevalence of HBsAg and total anti-HBc positivity increased from young to older age groups, yet the prevalence of anti-HBs positivity decreased from young to older age groups (P< 0.001 for all). There was no difference in the prevalences of HBsAg and anti-HBs among females and males (P= 0.108 and 0.089), but females had a higher prevalence than males for total anti-HBc positivity (P< 0.001). Discussion: This survey showed that in 2010 the prevalence of HBsAg among children aged less than five years was lower than the national target of 1.0% and that the prevalence of HBsAg for the total population was lower than the national target of 6.0%.

OBJECTIVETo evaluate the alterations in coagulation in patients during conditioning with modified busulfan plus cyclophosphamide (BU/CY) +/- antithymocyte globulin (ATG) regimen before allogeneic hematopoietic stem cell transplantation (allo-HSCT), and to assess the effect of ATG on coagulation system.

METHODSThirty-five patients with various hematological malignancies undergoing allo-HSCT were assessed. Of them, 19 patients with HLA-matched sibling donors (group A) were conditioned with modified BU/CY regimen, 16 with HLA-mismatched family members or HLA-matched unrelated donors (group B) were conditioned with modified BU/CY + ATG regimen. Blood samples were collected before the beginning of conditioning till d + 1 after allo-HSCT. The following parameters were measured: prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fg), antithrombin (AT), D-Dimer, fibrin degradation product (FDP), platelet (BPC), liver enzymes and bilirubin. FVIII: C, FIX: C, FXI: C and FXII: C in prolonged APTT blood samples were also determined. Clinical hemorrhagic symptoms were monitored.

RESULTSDuring conditioning, temporary lengthening of APTT, persistent rising in Fg and declining of BPC were observed in the two groups. Alterations of Fg and BPC were more significant in group B than in group A. Transient D-Dimer increase occurred only in group B on administration of ATG. Among intrinsic pathway coagulation factors, FXII: C and FXI: C were commonly decreased while APTT prolonged. No difference between the two groups was found with regard to PT, FDP, AT and liver parameters which remained in normal ranges. Most of patients in the two groups did not have overt bleeding manifestations.

CONCLUSIONSModified BU/CY +/- ATG conditioning regimen can induce subclinical alterations in coagulation. The regimen containing ATG has more significant effect on coagulation parameters.

OBJECTIVEHematologic relapse remains the greatest obstacle to the cure of acute lymphoblastic leukemia (ALL), especially T-lineage acute lymphoblastic leukemia (T-ALL) in children. Recent studies have shown that patients with increased risk of relapse can be identified by measuring residual leukemic cells, called minimal residual disease (MRD), during clinical remission. Current polymerase chain reaction (PCR) methods, however, for measuring MRD are cumbersome and time-consuming. To improve and simplify MRD assessment, the author developed a real-time quantitative PCR (RQ-PCR) assay for the detection of leukemic cells that harbor the tal-1 deletion. In addition, the author discussed the significance of MRD levels at different stages in treatment and prognosis of children with T-ALL.

METHODSA total of 50 consecutively enrolled patients with T-ALL were analysed for detection of leukemic cells harboring the most common tal-1 deletion. Serial dilutions of leukemic DNA were studied to find the sensitivity of detection with RQ-PCR assay. The MRD of 28 samples in clinical remission from 10 patients were quantified by RQ-PCR assay and limiting dilution assay. The results detected by both methods were compared statistically with correlation analysis.

RESULTS(1) A total of 10 patients presented tal-1 deletion involving the sildb1 breakpoint rearranged to tal1db1 in 50 cases with T-ALL. The breakpoints of relapsed samples are the same as those of the corresponding diagnostic samples; (2) The RQ-PCR assay had a sensitivity of detection of one leukemic cell among 100,000 normal cells. In 24 samples, MRD levels > 10(-5) could be detected with both methods. The percentages of leukemic cells measured by the two methods correlated well (r = 0.898, P < 0.001); (3) The MRD levels of 3 patients out of the 8 cases undergoing disciplinary regimen were over 10(-4) at the end of induction chemotherapy. They all relapsed in bone marrow during chemotherapy. The higher the MRD levels, the earlier the relapse. The other 5 patients with MRD levels < 10(-4) had been relapse-free survival (RFS) for 4-59 months, one of whom with increased MRD levels > 10(-4) for twice at the continuation stage had been RFS for 27 months till now.

CONCLUSIONSThe sildb1-taldb1 deletion presents in 20% of T-ALL, and is an ideal PCR marker for its specificity, uniform and stability; The tal-1 RQ-PCR can be used for the rapidly, sensitively and accurately quantitative assessment of MRD in T-ALL with the tal-1 deletion. MRD levels at different stages of chemotherapy have different significance in prognosis and treatment.
