Objective To study the pathogen distribution,risk factors and preventive measures in the patients with hospital-acquired septicemia. Methods Retrospective survey was carried out in 52 patients with hospital-acquired septicemia from 2007 to 2009. Results The hospital-acquired septicemia was related to the underlying disease and aggressive procedure. The most bacteria were Gram-negative bacilli and fungemia must be paid attention. Conclusion It is important to reduce the aggressive procedures and reasonably use antibiotics in the prevention of the hospital-acquired septicemia.

To explore the effect of estrogen on pathogenesis of osteoporosis in women with maintenance hemodialysis. One hundred and twenty women aged 18-45 years had been undergoing maintenance hemodialysis for ≥ 3 months were included. Of them ,60 women without osteoporosis served as control group and the other 60 women with osteoporosis as observation group. Serum concentrations of estradiol, tumour necrosis factor-α (TNF-α), parathyroid hormone (PTH), and calcium were determined, meanwhile bone mineral density (BMD)was measured by quantitative computed tomography. Serum estradiol levels in the observation group were lower while TNF-α level were higher than those in control group (all P<0. 05). PTH and calcium levels were not significantly different (P= 0.567 and P = 0. 588). In the observation group, linear correlation analysis revealed positive correlation (r = 0. 865 ,P<0. 01)between estradioi and BMD,while multiple linear regression analysis showed that serum estradiol and calcium levels were positively correlated with BMD, and the concentrations of TNF-α and PTH were negatively correlated with BMD (F= 140.32 ,P<0.01). Estradiol levels were found to have greater effect on BMD(t=5. 386, P<0. 01). Lowered serum concentration of estradiol in women with maintenance hemedialysis seems to be a major factor related to osteoporosis,it accelerates the pathogenesis of osteoporosis by modulating TNF-α.

OBJECTIVETo investigate the application of the Chinese Urological Association (CUA) Guidelines on Prostatitis and its effects on the clinical practice patterns of diagnosing and treating chronic pelvic pain syndrome (CPPS) among Chinese urologists and andrologists.

METHODSWe conducted a questionnaire investigation on the application of the CUA Guidelines on Prostatitis among the urologists and andrologists of 173 hospitals in 21 cities of China, and performed statistical analyses on all the eligible questionnaires collected.

RESULTSOf the 1 056 questionnaires distributed, 851 (80.6%) were eligible, of which 71.6% were from the urologists or andrologists in grade 3 hospitals, 80.7% of them with senior or intermediate professional titles and 97.5% had studied the CUA Guidelines. Most of the subjects agreed that Type III prostatitis is a clinical syndrome, whose diagnosis should exclude other conditions with similar symptoms, and whose treatment should aim at relieving pain, alleviating urination symptoms and improving the quality of life. Those who had and those who had not studied the CUA Guidelines differed in their viewpoints on CPPS as illustrated in the book. In clinical practice, the most common treatment options for CPPS were psychological therapy (80.7%), medication (80.4%) and life style adjustment (79.6%), and the most frequently used drugs were phytotherapy (80.0%), alpha-blockers (68.9%) and antibiotics (61.0%).

CONCLUSIONCUA Guidelines on Prostatitis has gained a nationwide application and promoted the standardization of the management of CPPS in China.

Objective To evaluate the clinical application and security of percutaneous endoscopic gastrostomy (PEG) with the Introducer method using ultrathin gastroseopy in dysphagia patients. Methods Clinical data of 22 cases dysphagia patients implemented with PEG with the Introducer method using ultrathin gastroseopy or conventional gastroseopy were retrospectively analyzed, the clinical effect and the complication were observed. Results 22 patients underwent PEG with the Introducer method using conventional gastroscopy (6 cases) or ultrathin gastroscopy (16 cases). Among the 16 patients underwent PEG using ultrathin gastroseopy by transnasal or peroral approach, 2 cases with trimus by received radiotherapy for nasopharyngeal cancer and 14 cases with pharyngeal or esophagus narrowing, could not completed PEG by conventional gastroscopy. The average procedure time of PEG was (12.2 ± 2.9) min in conventional gastroscopy group and (11.8 ± 3.2) min in control group. No complications were observed in these patients, but the patients in ultrathin gastroseopy group reported less discomfort associated with the procedure. 17 patients with advanced nasopharyngeal carcinoma and esophagus cancer who received PEG could completely finished 6 cycles of concurrent chemoradiotherapy. Paired-sample t test of nutrition indicators (hemoglobin, albumin and RBC) before and after the treatment showed significant difference (P < 0.05). Conclusion PEG with the introducer method using ultrathin gastroseopy is a safe and effective method of enteral nutrition, Ultrathin gastroscopy reduces the discomfort of the procedure, especially in patients with serious trimus and pharyngeal or esophagus narrowing. For patients with advanced nasopharyngeal carcinoma, preventative PEG improved the tolerance of chemoradiotherapy,reduce the incidence of adverse events.

OBJECTIVETo translate the English version of The Premature Ejaculation Diagnostic Tool (PEDT) into Chinese, evaluate its reliability and validity, and analyze its feasibility in the diagnosis of premature ejaculation (PE).

METHODSFollowing the forward-backward translation procedure, we developed the Chinese version of PEDT, which was then revised by andrologists and bilingual linguists. We enrolled subjects with or without PE from 15 urological or andrological clinics in China and obtained the information about their demographic characteristics, PEDT scores, and intra-vaginal ejaculation latency time (IELT). We evaluated the internal consistency of PEDT using Cronbach alpha, was examined its reliability and stability by test-retest analysis, analyzed its correlation with IELT by Spearman correlation analysis, and tested its sensitivity and specificity by receiver operating characteristic ( ROC) analysis.

RESULTSTotally, 570 PE patients (aged [30.66 ± 7.11] years) and 226 non-PE men (aged [33.01 ± 5.41] years) were recruited, with the mean IELT of (1.34 ± 0.54) min in the former and (11.09 ± 7.5) min in the latter group. The Cronbach's alpha of the Chinese version of PEDT was 0.79, and the test-retest correlation coefficient was 0.75 (P < 0.01). The PEDT score was negatively correlated with IELT (Spearman's p = -0.52, P < 0.01). When the cutoff value of PE diagnosis was defined as 7.5, the sensitivity and specificity of PEDT were 0.80 and 0.78, and when as 8.5, they were 0.72 and 0.89, respectively.

CONCLUSIONThe Chinese version of PEDT was demonstrated to have good internal consistency, reliability, and validity, as well as a high predictability for PE. It can be used as a reliable and convenient tool to screen PE among Chinese men.

OBJECTIVETo observe the efficacy of Qilin Pills in the treatment of oligoasthenospermia.

METHODSWe conducted a multi-centered open controlled clinical trial by including 220 oligoasthenospermia patients in a trial group and another 110 as controls. The patients in the trial group were treated with Qilin Pills at the dose of 6 g tid, and the controls given Wuziyanzong Pills at 6 g bid, both for a course of 12 weeks. Then we evaluated the clinical effects of Qilin Pills with sperm concentration, the numbers of grade a and grade a + b sperm, and sperm motility as the primary, and the pregnancy rate of the patients'spouses as the secondary therapeutic indexes.

RESULTSA total of 310 patients accomplished the clinical trial, 208 in the trial and 102 in the control group. Compared with the baseline, significant improvement was observed in the semen parameters after 4, 8 and 12 weeks of treatment in both the trial and control groups except sperm density and the number of grade a sperm in the control after 4 weeks (P < 0.01), and the improvement was even more significant in all the semen parameters at the same time points in the trial than in the control group (P < 0.01).

CONCLUSIONQilin Pills can evidently improve the seminal quality of oligoasthenospermia patients with no obvious adverse events.

BACKGROUNDThe prevalence of malnutrition is very high in patients with cancer. The purpose of this study was to investigate whether or not a nutrition support team (NST) could benefit esophageal cancer patients undergoing chemoradiotherapy (CRT).

METHODSBetween June 2012 and April 2014, 50 esophageal cancer patients undergoing concurrent CRT were randomly assigned into two groups: The NST group and the control group. The nutritional statuses of 25 patients in the NST group were managed by the NST. The other 25 patients in the control group underwent the supervision of radiotherapy practitioners. At the end of the CRT, nutritional status, the incidence of complications, and completion rate of radiotherapy were evaluated. Besides, the length of hospital stay (LOS) and the in-patient cost were also compared between these two groups.

RESULTSAt the completion of CRF, the nutritional status in the NST group were much better than those in the control group, as evidenced by prealbumin (ALB), transferrin, and ALB parameters (P = 0.001, 0.000, and 0.000, respectively). The complication incidences, including bone marrow suppression (20% vs. 48%, P = 0.037) and complications related infections (12% vs. 44%, P = 0.012), in the NST group were lower and significantly different from the control group. In addition, only one patient in the NST group did not complete the planned radiotherapy while 6 patients in the control group had interrupted or delayed radiotherapy (96% vs. 76%, P = 0.103). Furthermore, the average LOS was decreased by 4.5 days (P = 0.001) and in-patient cost was reduced to 1.26 ± 0.75 thousand US dollars person-times (P > 0.05) in the NST group.

CONCLUSIONSA NST could provide positive effects in esophageal cancer patients during concurrent CRT on maintaining their nutrition status and improving the compliance of CRF. Moreover, the NST could be helpful on reducing LOS and in-patient costs.

Inflammatory diseases are common medical conditions seen in disorders of human immune system. There is a great demand for anti-inflammatory drugs. There are major inflammatory mediators in arachidonic acid metabolic network. Several enzymes in this network have been used as key targets for the development of anti-inflammatory drugs. However, specific single-target inhibitors can not sufficiently control the network balance and may cause side effects at the same time. Most inflammation induced diseases come from the complicated coupling of inflammatory cascades involving multiple targets. In order to treat these complicated diseases, drugs that can intervene multi-targets at the same time attracted much attention. The goal of this review is mainly focused on the key enzymes in arachidonic acid metabolic network, such as phospholipase A2, cyclooxygenase, 5-lipoxygenase and eukotriene A4 hydrolase. Advance in single target and multi-targe inhibitors is summarized.

The limited treatment options for advanced prostate cancer (PCa) lead to the urgent need to discover new anticancer drugs. Mannose, an isomer of glucose, has been reported to have an anticancer effect on various tumors. However, the anticancer effect of mannose in PCa remains unclear. In this study, we demonstrated that mannose inhibits the proliferation and promotes the apoptosis of PCa cells in vitro, and mannose was observed to have an anticancer effect in mice without harming their health. Accumulation of intracellular mannose simultaneously decreased the mitochondrial membrane potential, increased mitochondrial and cellular reactive oxygen species (ROS) levels, and reduced adenosine triphosphate (ATP) production in PCa cells. Mannose treatment of PCa cells induced changes in mitochondrial morphology, caused dysregulated expression of the fission protein, such as fission, mitochondrial 1 (FIS1), and enhanced the expression of proapoptotic factors, such as BCL2-associated X (Bax) and BCL2-antagonist/killer 1 (Bak). Furthermore, lower expression of mannose phosphate isomerase (MPI), the key enzyme in mannose metabolism, indicated poorer prognosis in PCa patients, and downregulation of MPI expression in PCa cells enhanced the anticancer effect of mannose. This study reveals the anticancer effect of mannose in PCa and its clinical significance in PCa patients.
