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 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%.

BACKGROUNDPercutaneous coronary intervention (PCI) is indicated for angina with coronary stenosis. However, PCI for asymptomatic coronary stenosis remains controversial. We prospectively followed a group of patients for four years who underwent coronary computed tomography angiography (CCTA) for major adverse cardiac events (MACE). We hypothesized that the results of this trial would reliably reflect the natural outcome of the coronary disease.

METHODSConsecutive patients who underwent CCTA from June 2008 to May 2009 were selected. Those who could not be reached by telephone, had significant angina, had CT images that were not interpretable, or poor kidney and left ventricular (LV) function were excluded. The patients were divided into five groups: group A normal CCTA without stenosis, group B mild stenosis (1% - 49%), group C moderate stenosis (50% - 74%), group D severe stenosis (= 75%) and they were treated with optimal medical therapy (OMT) or PCI. The group E had PCI before the CCTA examination. The patients were then followed for MACE after different treatments. MACE included acute myocardial infarction (MI), heart failure (HF) and death.

RESULTSThe patient population consisted of 419 patients. The follow-up time was (51 ± 5) months. The age was (60 ± 31) years. Male made up 67.78% of the population (n = 284). A total of 51 cases of MACE occurred including 25 MI, eight HF and 18 all-cause deaths. There was no MACE in group A. Although MACE occurred in two patients in group B, they were not attributed to cardiac death. We further compared the MACE in groups C-E and no significant difference was found (P > 0.05). However, a difference was detected among patients with unstable angina pectoris (UAP), stable angina pectoris (SAP), re-hospitalization, and cerebrovascular events from groups A-E (P < 0.05). The plaque scores were used to predict MACE. The scores progressively increased significantly with lesion severity (P < 0.05). Receiver operating curve (ROC) was performed to determine the sensitivity and specificity in predicting MACE. Our scores predicted MI with area of 0.76, predicted HF with area of 0.77, and predicted death with area of 0.70.

CONCLUSIONSNormal and mild lesions had very few events. With increased stenosis the MACE rate increased progressively. PCI did not significantly reduce the MACE in comparison with OMT in asymptomatic patients. Furthermore, UAP, re-hospitalization, and re-PCI were significantly increased in patients who were treated with PCI.

OBJECTIVETo explore the biological function of vascular endothelial cells from hypertrophic scar, and to analyze the relationship between them.

METHODSThe samples from human hypertrophic scar and normal skin tissue were harvested for histological examination. Then vascular endothelial cells were purified and isolated from the samples, and the level of transforming growth factor (TGF) beta1, platelet derived growth factor (PDGF), endothelin1 (ET)-1, fibroblast growth factor (FGF)2 and vascular endothelial growth factor (VEGF) were determined in a single cell with ELISA.

RESULTSFew capillary vessels were observed in normal skin under microscope, while an increased number of them were present in hypertrophic scar, with slender, tortuous in morphology and even occluded. The diameter of blood capillary in hypertrophic scar was tiny under electron microscope, and the exfoliation of endothelial cells was observed. The levels of TGF-beta1, PDGF, ET-1, bFGF and VEGF from vascular endothelial cells from hypertrophic scar were 60 +/- 8, 30 +/- 4, 0.12 +/- 0.03, 52 +/- 5, 18.1 +/- 1.2 microg/cell, respectively, which were obviously lower than those in normal skin (P < 0.05).

CONCLUSIONThe biological function of vascular endothelial cells was attenuated in the hypertrophic scar, which mightbe the result of the production of large amounts of collagen in the scar tissue, as well as hypoxia.
