Objective To investigate the diagnosis and treatment of septic shock and multiple organ dysfunction syndrome (MODS) following transrectal ultrasound-guided prostate biopsy (TRUSPB). Methods We reported two cases,45 and 46 years old,of septic shock and MODS after TRUSPB from June 1996 to May 2011.10 cases like these two cases in literatures were acquired (3 cases in Chinese and 7 cases in English) from 1991 to 2011,and the causes of severe infections following transrectal prostate biopsy and its prophylactic procedures were discussed as well. Results The two cases,suffered postoperative septic shock and MODS 16 -40 h after being smoothly performed TRUSPB.One patient died four days after surgery and the other improved after five days antibiotic treatment.All the 12 cases had abrupt onsets and deteriorated rapidly,2 cases died and 1 case was performed amputation due to double lower limb gangrene,resulted in high mortality and morbidity.There are many risk factors,such as repeated puncture (4/12),diabetes (3/12),chronic infections (3/12) and used immune suppression (1/12),et al; blood culture was positive in 9 case and E.coli bacteria was the main bacteria(8/9),besides,half of them were multi-drug resistant (4/8) and other 2 cases were ESBLs ( + ) or 1 case was quinolone-resistant repectively.9 cases recovered after actively controlled infection using carbapenem and other treatment. Conclusions Transrectal ultrasound-guided prostate biopsy could cause serious complications such as septic shock,to which more attentions should be paid.Preoperative use of carbapenem should be recommended for patients with repeating biopsy or other risk factors.

The microarrays have revolutionised biomedical experimentation and diagnostics, enabling ordered high throughput analysis. During the past decade, classic solid phase substrates, such as microlitre plates, membrane filters and microscopic slides, were turn into high-density, chip-like structure. The concept of the arrayed library was central to this development which now extends from DNA to protein. The availability of such protein microarrays would facilitate the simultaneous analysis of thousands of interactions within a single experiment. They can be utilized for massively parallel testing of protein function or recognized their target polypeptide in complex biological solution. This article will focus on the current strategies used to generate protein microarray and their applications in biological research, medicine and diagnostics.

4.Testicular dysgenesis syndrome: an update.
National Journal of Andrology 2010;16(12):1113-1116
Researches on the testicular dysgenesis syndrome (TDS) have flourished in the recent decade, and a widely accepted view on its pathogenesis is that environmental endocrine disrupting chemicals (EDCs) act on Leydig cells and/or testicular Sertoli cells, resulting in abnormal development of the testis and leading to the symptoms of TDS. Molecular biological studies suggest a correlation of TDS etiology with insulin-like factor 3 (INSL-3), androgen receptor (AR), P27kip, WT-1 and Müllerian inhibiting substance (MIS). This review focuses on the progress in current researches on the etiology and mechanism of TDS.

Objective The aim of this study is to explore the influence of hypertension on life expectancy (LE), active life expectancy (ALE) and active life expectancy/life expectancy (ALE/LE) among senior citizens in Beijing. Methods The sample derived from Beijing multidimensional longitudinal study on aging, baseline survey consisted of 1847 elderly people aged 60 years and over dwelling in the communities from one urban district (Xuanwu),one suburban country (Daxing) and one mountainous country (Huairou) in Beijing, 2004. Cluster, stratified and randomly selected sampling technique was used and a follow-up program was carried out in 2007. The subjects were invited to fill in questionnaires at home through well-trained interviewers, together with medical history of hypertension and repeated blood pressure measurements adopted. The state of activity was defined according to whether they could perform activities of daily life (ADL). IMaCH software for multi-state life table method was used to calculate the life expectancy(LE), active life expectancy (ALE) and active life expectancy/life expectancy(ALE/LE) in people with hypertension and normal blood tension, as well as on those people with hypertension with or without cardio-cerebral disease.Results The study manifested that hypertensives were associated with the reduction of LE,ALE and ALE/LE compared to the normotensives. The ALE/LE was descending along with ageing, and the speed of reduction was much faster in the hypertensive group, especially within senile population. LE,ALE and ALE/LE among the hypertensives with cardio-cerebral vascular diseases were shorter than the hypertensives without the disease. Difference in ALE/LE was striking in people with virile senility.Conclusion Hypertension remarkably impacted the active life expectancy on senior citizens living in Beijing, especially for elderly. Hypertensives with cardio-cerebral vascular diseases exerted further influence on active life expectancy, particularly among population of virile senility. The finding underlined the tremendous importance of preventing high blood pressure and its complication.

Objective To explore the regional disparity in life expectancy (LE), active life expectancy (ALE), active life expectancy/life expectancy (ALE/LE) of the elderly in Beijing and to express the impact of hypertension upon those indices. Methods The sample was derived from a 'Beijing multidimensional longitudinal study on aging', including those from urban district (Xuanwu), rural district (Daxing and Huairou) by well-established statistical sampling techniques. Baseline survey comprised 1847 people aged 60 years or over, living in the communities in Beijing in 2004. The subjects under research were investigated with questionnaires at home by well-trained interviews and the contents would include: degree of education, occupation, medical history of hypertension together with repeated blood pressure measurements. Someone being 'active' was defined as the ability in performing activities of daily life (ADL). IMaCH software for multi-state life table method was used to calculate the life expectancy (LE), active life expectancy (ALE) and active life expectancy/life expectancy (ALF/LE) in different district and the hypertensive exert influence on those indices. Results Data from the study showed that people inhabited in the rural district had lower LE, ALE and degree of education (illiteracy account for 66.2 percentage), but with more physical activities (account for 95.5 percentage) and higher ALE/LE than urban district people.Regional disparity in Females was obvious than in males while hypertension would exert more influence on LE of the urban women, which widened the gap in LE, ALE of males and ALE of females between the urban and rural areas. Conclusion Regional disparity was found existing in LE,ALE, ALE/LE of the elderly from Beijing, particularly in females. Hypertension widened the gap and decreased the quality of life on senior citizens in the rural areas. This finding underlined the influence of habitation on the quality of life which manifested the importance of prevention regarding high blood pressure.

OBJECTIVETo study the impact of the chloride channel dysfunction of the cystic fibrosis transmembrane conductance regulator (CFTR) on the cytoskeleton of Sertoli cells in the mouse.
METHODSTM4 Sertoli cells were cultured and treated with CFTR(inh)-172 at the concentrations of 1, 5, 10 and 20 μmol/L for 48 hours. Then the cytotoxicity of CFT(inh)-172 was assessed by CCK-8 assay, the expressions of F-actin and Ac-tub in the TM4 Sertoli cells detected by immunofluorescence assay, and those of N-cadherin, vimentin and vinculin determined by qPCR.
RESULTSCFTR(inh)-172 produced cytotoxicity to the TM4 Sertoli cells at the concentration of 20 μmol/L. The expressions of F-actin and Ac-tub were decreased gradually in the TM4 Sertoli cells with the prolonging of treatment time and increasing concentration of CFTR(inh)-172 (P < 0.05). The results of qPCR showed that different concentrations of CFTR(inh)-172 worked no significant influence on the mRNA expressions of N-cadherin, vimentin and vinculin in the Sertoli cells.
CONCLUSIONThe CFTR chloride channel plays an important role in maintaining the normal cytoskeleton of Sertoli cells. The reduced function and expression of the CFTR chloride channel may affect the function of Sertoli cells and consequently spermatogenesis of the testis.

OBJECTIVETo investigate the feasibility and safety of autologous peripheral blood hematopoietic stem cell transplantation (auto-PBHSCT) and its therapeutic effect on refractory rheumatism among preschool children.
METHODSThree boys with juvenile rheumatoid arthritis (JRA), juvenile systemic lupus erythematosus (JSLE) and juvenile dermatomyositis (JDM) respectively, 3 to 6 years old with the mean age of 5 years with 3.5 to 22 months course of disease with 14 months on average, received auto-PBHSCT. Their conditions were so severe that conventional therapy failed to control the diseases. The changes of both clinical manifestations and immunologic indexes were observed before and after transplantation with long term following up at specialty clinic of rheumatism.
RESULTThe time when neutrophil count >or= 0.5 x 10(9)/L in the 3 children was days +9, +13 and +11 respectively, that of platelet count >or= 20 x 10(9)/L was days +14, +18 and +13 respectively. The cellular immune function remained abnormal with CD4 cells at a low level and CD4/CD8 being inverted. As to the JDM child, the skin rash had disappeared and his muscle tone was improved to grade 5 within one month after the transplantation. The EMG and serum creatase level returned to normal and muscle MRI findings were improved greatly within 2 months after the transplantation. As to the JSLE child, skin rash and proteinuria had disappeared, MRI of brain showed that the pathological changes had been absorbed and EEG returned to normal 3 months after the transplantation, all the autoantibodies turned to negative within 8 months after transplantation. As to the JRA child, the arthritis had been improved remarkably within 3 weeks after auto-PBHSCT. There was no swelling of joints nor movement limitation 3 months post transplantation. The steroids and immunosuppressive drugs were discontinued post transplantation. Cushing syndrome disappeared. Their body heights increased by 10 to 15 cm in the past 18 months, and they all returned to school. There was no relapse during follow-up periods of 25 - 27 months.
CONCLUSIONThe therapy with auto-PBHSCT for refractory rheumatism among preschool children was remarkably effective in a short-term, yet the safety and long-term effect still need to be further studied.
