Association between Allergic Diseases and Irritable Bowel Syndrome: A Retrospective Study.

Background: The relationship between allergic disease and irritable bowel syndrome (IBS) is poorly understood. We aimed to investigate the potential association as well as the underlying immunological mechanisms.

Methods: A retrospective case-control study of 108 atopic patients from among outpatients in an allergy clinic (allergic rhinitis [AR], n = 49; chronic urticaria [CU], n = 59) and 74 controls from among ward companions was conducted from November 2016 to March 2017.

Satellite-based entanglement distribution over 1200 kilometers.

Long-distance entanglement distribution is essential for both foundational tests of quantum physics and scalable quantum networks. Owing to channel loss, however, the previously achieved distance was limited to ~100 kilometers. Here we demonstrate satellite-based distribution of entangled photon pairs to two locations separated by 1203 kilometers on Earth, through two satellite-to-ground downlinks with a summed length varying from 1600 to 2400 kilometers.

Chinese physicians' perceptions of fecal microbiota transplantation.

Aim: To explore Chinese physicians' perceptions towards fecal microbiota transplantation (FMT) and to provide information and an assessment of FMT development in China.

Methods: A self-administered questionnaire was developed according to the FMT practice guidelines and was distributed to physicians in hospitals via Internet Research Electronic Data Capture (REDcap) software and electronic mails to assess their attitudes toward and knowledge of FMT. The questionnaire included a brief introduction of FMT that was followed by 20 questions.

Process development of short-chain polyols synthesis from corn stover by combination of enzymatic hydrolysis and catalytic hydrogenolysis.

Currently short-chain polyols such as ethanediol, propanediol, and butanediol are produced either from the petroleum feedstock or from the starch-based food crop feedstock. In this study, a combinational process of enzymatic hydrolysis with catalytic hydrogenolysis for short-chain polyols production using corn stover as feedstock was developed. The enzymatic hydrolysis of the pretreated corn stover was optimized to produce stover sugars at the minimum cost.

[Expression of vascular growth factors in intestinal tissues in colorectal carcinoma patients with schistosomiasis japonica].

Objective: To investigate the differences of mRNA quantitation and protein expression of vascular growth factors including platelet-derived endothelial cell growth factor (PD-ECGF) and vascular endothelial growth factor (VEGF) in intestinal tissues in colorectal carcinoma patients with and without schistosomiasis.

Methods: Thirty colorectal carcinoma patients with schistosomiasis and 30 colorectal carcinoma patients without schistosomiasis were included in this study. The mRNA quantitation and protein expression of PD-ECGF and VEGF in the normal tissue, peri-carcinoma tissue as well as carcinoma tissue obtained from surgical specimens were detected by qRT-PCR and Western blot.

[Clinical investigation on schistosomiasis after a 16-year-interruption program regarding its transmission, in Jiaxing region of Zhejiang province].

Objective: To investigate the epidemic pattern, diagnosis and treatment of schistosomiasis after the 16-years intervention program on its transmission in Jiaxing region of Zhejiang province.

Methods: Clinical data of schistosomiasis patients during the last 10 years and pathological specimens with deposited schistosomal eggs during the last 8 years were retrospectively analyzed.

Results: The total numbers of schistosomiasis patients admitted to hospital increased from 194 in 2001 to 960 in 2010, and from 78 to 266 with complications.

[Qianlie Jiedu capsule combined with rufloxacin for chronic prostatitis: a randomized double-blind controlled clinical trial].

Objective: Few double-blind controlled trials have been reported on Chinese patent medicines for the treatment of chronic prostatitis. The purpose of this study was to investigate the therapeutic efficacy of Qianlie Jiedu Capsule for chronic prostatitis (CP) by the randomized double-blind controlled method.

Methods: Eighty CP patients were equally randomized into an experimental and a control group, the former treated with Qianlie Jiedu Capsule + Rufloxacin, and the latter given placebo + Rufloxacin, both for 4 weeks.

Downregulation of survivin by RNAi inhibits growth of human gastric carcinoma cells.

Aim: To investigate the inhibitory effect of a specific small survivin interfering RNA (siRNA) on cell proliferation and the expression of survivin in human gastric carcinoma cell line SGC-7901.

Methods: To knockdown survivin expression, a small interfering RNA targeting against survivin was synthesized and transfected into SGC-7901 cells with lipofectamine 2000. The downregulation of survivin expression at both mRNA and protein levels were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis.

[Factors influencing the development of portal hypertensive gastropathy with liver fibrosis in schistosomiasis].

Objective: To evaluate the factors influencing the development of portal hypertensive gastropathy (PHG) with liver fibrosis in schistosomiasis japonica.

Methods: A retrospective study was executed on 196 hospitalized patients with schistosomiasis liver fibrosis (109 of them complicated with PHG) from 1998 to 2002. Endoscopic examinations were carried out for all the cases.
