Objective To identify and investigate the cause of the unacceptable bacteria level inside the lumen of fiberendoscope during monitoring so as to increase the pass rate of its cleaning and disinfection. Methods A failure mode effect analysis of the cause was done and the workflow was thereafter improved. Meanwhile, pre and post bacteriological monitor was applied to the fiberendoscope lumen samples. Results The number of scrubbing times while manual cleaning affected the monitoring results. The scrubbing times was amended and the pass rate increased from 84.15% to 98.65%. The results were significantly different The failure mode risk index of endoscope cleaning and disinfection was calculated, and the highest two items were: The number of scrubbing times the operators execute RPN=640, the method of lumen cleaning RPN=480. These were the key factors of qualification of monitoring. Conclusions After the amendment, no less than 5 times' scrubbing was required and the bacteriological monitoring method was used to analyze the effects,thereafter the pass rate of lumen bacteria monitoring can be increased significantly.

OBJECTIVETo explore the therapeutic effects of combination of varicocelectomy with hyperbaric oxygenation (HBO) in treating infertile patients with varicocele.

METHODSNinety-six patients were randomly divided into two groups: 40 patients in group A treated by varicocelectomy with HBO, and 56 in group B treated by solitary varicocelectomy.

RESULTSThe sperm density, sperm motility, sperm vigor, normality, serum testosterone, the pregnant rate of patients spouses were improved respectively in both two groups (P <0.01 or P < 0.05), and group A had better results than group B (P < 0.05). LH, FSH in group A decreased significantly after the therapy. Group A had higher sperm penetration asay (SPA) percentages than group B(P < 0.05), and the pregnant time of patient's spouses in group A was earlier than that in group B (P < 0.05).

CONCLUSIONVaricocelectomy with HBO can more effectively regulate reproductive hormone, improve semen quality, SPA index and pregnant rate than solitary varicocelectomy in treating infertile patients with varicocele and can markedly shorten the pregnant time.

OBJECTIVETo investigate the expression of PTEN and Caspase-3 in malignant lymphoma of the stomach and explore their role in progression of primary gastric malignant lymphoma.

METHODSFormalin-fixed paraffin embedded tissues from 56 cases of primary gastric malignant lymphoma and their adjacent non-tumor mucosa were evaluated for PTEN and Caspase-3 protein expression by streptavidin-biotin-complex (SABC) immunohistochemistry. Their expression was compared with clinical tumor parameters with the relationship between PTEN and Caspase-3 expression concerned as well.

RESULTSThe positive rate of PTEN expression in primary gastric lymphomas (50.0%, 28/56) was significantly lower than that in adjacent non-tumor gastric mucosa (96.4%, 27/28) (P < 0.05). Meanwhile, 43 of 56 (76.8%) gastric lymphomas indicated Caspase-3 expression, less than that in adjacent non-tumor mucosa (93.5%, 29/31) (P < 0.05). The expression of PTEN was negatively correlated with invasion and lymph node metastasis of gastric lymphoma (P < 0.05), while the Caspase-3 expression was negatively associated with the latter one (P < 0.05). Additionally, the PTEN expression was positively correlated with Caspase-3 expression in the primary gastric malignant lymphoma (P < 0.05).

CONCLUSIONSThe down-regulated expression of PTEN and Caspase-3 played an important role in progression of primary malignant gastric lymphoma. PTEN, as a molecular marker of pathobiological behaviors of tumor, contributes to tumor progression by increasing cell mobility and angiogenesis, as well as decreasing cell adhesion and apoptosis.

BACKGROUNDIt has been known that Kai1 is one of transmembrane 4 superfamily regulating cell proliferation, adhesion and mobility and its down-regulated expression is closely correlated with progression and prognosis of tumor. Fas ligand (FasL) is one of tumor necrosis factor/nerve growth factor family activating caspase-3, a key proteinase in cell apoptosis and leading immune escape in tumor cells. The aim of this study is to investigate the expression of Kai1 and FasL in non-small cell lung cancer (NSCLC) and to explore their roles and relationship in carcinogenesis and progression of NSCLC.

METHODSKai1 and FasL expressions were examined in 79 NSCLC tissues and their adjacent normal lung tissues by SP immunohistochemistry. Their expressions were compared with clinicopathological features of NSCLC. The relationship between Kai1 and FasL expressions was also analyzed in NSCLC.

RESULTSKai1 expression in NSCLC tissue was remarkably lower than that in their adjacent tissue (55.7% vs 82.6%, P < 0.05). However, it was the converse for FasL (73.4% vs 52.2%, P < 0.05). Kai1 expression was not correlated with age and gender of NSCLC patients, tumor location or histological classification (P > 0.05), but negatively with lymph node metastasis and clinicopathological staging and positively with differentiation degree (P < 0.05). FasL expression was not correlated with age and gender of the patients, tumor location or histological classification (P > 0.05), but positively with lymph node metastasis and negatively with differentiation degree (P < 0.05). Kai1 expression was closely correlated with FasL expression in NSCLC (P < 0.05).

CONCLUSIONSDown-regulation of Kai1 expression and up-regulation of FasL may play important roles in carcinogenesis and progression of NSCLC. Kai1 and FasL could be considered as molecular markers to reflect pathobiological behavior of NSCLC. Additionally, close correlation of FasL expression with Kai1 expression in NSCLC provides a novel insight into the regulatory effects of FasL expression on Kai1 expression.

Glioblastoma (GBM), characterized by rapid progression, easy recurrence and treatment resistance, is the most aggressive and lethal tumor of the central nervous system. Adenovirus E1A binding protein p300 (p300) serves rich functions as transcriptional coactivator and lysine acetyltransferase. Studies have shown that p300 plays an important role in the occurrence, proliferation, invasion and resistance to chemoradiotherapy of GBM. This paper reviews the structure and function of p300, and systematically expounds its various ways participating in GBM development and its translational perspectives, so as to provide references for GBM study.

Objective:To study the neural mechanism between abnormal brain functional activity and alertness function in temporal lobe epilepsy (TLE) patients with or without hippocampal sclerosis.Methods:A total of 21 TLE patients with hippocampal sclerosis (TLE-HS), and 18 TLE patients without hippocampal sclerosis (TLE-N) diagnosed in the Department of Neurology of the First Affiliated Hospital of Guangxi Medical University from May 2016 to November 2022 and 28 healthy controls (HC) matched with demographic data were recruited.All the 67 participants completed the attention network test (ANT) and resting-state fMRI (rs-fMRI) scans. The REST software was used to analyze fractional amplitude of low-frequency fluctuation (fALFF) and functional connectivity (FC) based on one-way ANOVA in order to obtain differential brain regions in abnormal spontaneous neuronal activity and functional connectivity among the three groups. The SPSS 26.0 software was used to analyze the correlation between fALFF/FC values in differential brain regions and alertness network efficiency by Pearson correlation analysis.Results:There was a significant difference in the alerting network effect among the three groups ( F=4.621, P=0.013), and the post-hoc analysis showed that the alerting network effect in the TLE-HS group((59.40±22.85)ms)was significantly higher than that in the HC group((38.85±21.08)ms)(Bonferroni correction, P=0.017). The fALFF analysis showed that the fALFF values of the right superior frontal gyrus in the TLE-HS group (0.16±0.52) and the TLE-N group (0.49±0.51) were significantly lower than that in the HC group (1.01±0.46), while the fALFF values of the left precentral gyrus in the TLE-HS group (0.60±0.55) was significantly higher than that in the TLE-N group (-0.19±0.51) and the HC group (-0.15±0.36) (Bonferroni correction, all P<0.05). The functional connectivity analysis revealed that the FC values between the left inferior frontal gyrus and the right superior frontal gyrus in the TLE-HS group (0.11±0.16) and TLE-N group (0.02±0.19) were significantly higher than those in the HC group (-0.18±0.18). The FC values between the right supramarginal gyrus and the right superior frontal gyrus in the TLE-HS group (0.10±0.21) were significantly higher than those in the HC group (-0.18±0.16). The FC values between the left supplementary motor area and the right superior frontal gyrus in the TLE-HS group (0.20±0.21) were significantly higher than those in the TLE-N group (-0.03±0.31) and the HC group (-0.10±0.15) (Bonferroni correction, all P<0.05). The correlation analysis showed that the FC values between the left supplementary motor area and the right superior frontal gyrus in the TLE-HS group were significantly positively correlated with alertness network efficiency ( r=0.436, P=0.048). Conclusions:There are abnormal spontaneous neuronal activity and brain functional connectivity in TLE patients with or without hippocampal sclerosis, and the abnormality is more pronounced in the TLE-HS group. The abnormal brain functional connectivity may play an essential role in alertness dysfunction.

Health communication is the most core element in health education and health promotion.This paper summarizes and analyzes the research in China related to the evaluation of health communication effects through different media.It finds that the current evaluation indicators of communication effects are generally focused on changes in awareness rates.Traditional media and new media,as different types of communication mediums with their own advatages and limitations,do not have unified indicators to scientifically evaluate their communication effects in China,Due to the interdisciplinary nature of health communication,qualitative research methods(such as the Delphi method)have not been fully applied by researchers in the field of public health in China.This paper aims to sort out and compare various effects evaluation indicatorsof health communication with different media from current research through a literature review,and to provide evidences for improving a comprehensive and practical effect evaluation system of health communication in the future.
