Background:Irritable bowel syndrome(IBS)is a commonly seen functional intestinal disorder. Dietary factors are important factors affecting the abdominal symptoms of IBS patients. Aims:To investigate the effect of dietary factors on abdominal symptoms of IBS and the application of dietary adjustment strategy in patients lived in Xian,Shaanxi Province and the surrounding areas. Methods:Fifty-four outpatients with abdominal complaints who met the Rome Ⅲ criteria of IBS from Feb. 2015 to Jul. 2015 at the Second Affiliated Hospital of Xian Jiaotong University were enrolled. Twenty healthy volunteers were served as controls. All subjects completed a questionnaire containing issues mainly on IBS symptoms, eating habits,dietary factors causing abdominal symptoms,and the patients’coping styles. Results:Compared with healthy controls,more rice and less spicy food,fatty food,raw/ cold food,acidic beverages and alcohol drinking were observed in diet of IBS patients(P all < 0. 05). Abdominal symptoms of IBS patients could be caused or exacerbated predominantly by cold food(55. 6% ),fatty food(55. 6% ),raw food(48. 1% ),meat(48. 1% )and spicy food (40. 7% ). More than half of the IBS patients(63. 0% ) adopted an elimination diet to minimize their abdominal symptoms. Spicy food(59. 3% ),raw food(48. 1% ),cold food(44. 4% ),fatty food(44. 4% )and meat(37. 0% ) were the most frequently eliminated classes of food. Conclusions:Dietary factors can affect the abdominal symptoms of IBS in patients lived in Xian,Shaanxi Province and the surrounding areas and elimination diet based on foods they perceive as problematic is widely used. The classes of food and eating habits causing abdominal symptoms are quite different between domestic and overseas IBS patients.

Objective To investigate the influence of heparin pretreatment on serum and lung tissue level of neutrophil extracellular traps (NETs) in septic mice model and its molecular mechanism.Methods Ninety male C57BL/6J mice were randomly divided into control group (n = 30), lipopolysaccharides (LPS) group (n = 30, 30 mg/kg LPS in 100μL normal saline was intraperitoneally injected) and LPS+heparin group (n = 30, 8 U of heparin in 20μL normal saline was subcutaneously injected 30 minutes before the injection of LPS). Six hours later of LPS injection, blood was collected and lung tissue was harvested. Enzyme linked immunosorbent assay (ELISA) was used to assess the concentration of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and histones 2AX (H2AX), neutrophil elastase (NE), which reflected NETs concentration. PicoGreen fluorescent dyes was used to detect serum circulating free DNA (cf-DNA/NETs) concentration. The protein expression levels of H2AX and NE in lung tissue were examined by Western Blot.Results The serum concentrations of TNF-α, IL-6, H2AX, NE, cf-DNA/NETs, and the protein expression levels of H2AX and NE in lung tissue of septic mice were significantly higher than those of control group [TNF-α (ng/L): 133.0±14.1 vs. 2.7±1.0, IL-6 (ng/L): 3911.2±189.2 vs. 298.9±52.5, H2AX (ng/L): 545.5±40.0 vs. 21.9±8.3, NE (μg/L): 6.48±0.12 vs. 0.47±0.15, cf-DNA/NETs (μg/L): 846.3±137.5 vs. 152.7±36.4, H2AX protein (gray value): 1.14±0.09 vs. 0.68±0.04, NE protein (gray value): 0.56±0.03 vs. 0.32±0.04, allP < 0.05]. After heparin pretreatment, levels of serum TNF-α, H2AX, NE, cf-DNA/NETs, and protein expression levels of H2AX and NE in lung tissue were significantly reduced [TNF-α (ng/L): 83.2±7.6 vs. 133.0±14.1, H2AX (ng/L): 435.0±39.0 vs. 545.5±40.0, NE (μg/L): 4.26±0.17 vs. 6.48±0.12, cf-DNA/NETs (μg/L): 606.5±73.9 vs. 846.3±137.5, H2AX protein (gray value): 0.91±0.03 vs. 1.14±0.09, NE protein (gray value): 0.42±0.03 vs. 0.56±0.03, allP < 0.05], but no significant change was found in IL-6 (ng/L: 3919.9±166.6 vs. 3911.2±189.2,P > 0.05).Conclusion Heparin pretreatment could significantly decrease the level of NETs in serum and lung tissue, and can be the potential mechanism of its organ protection in sepsis.

Objective To study the nutritional risks in elderly patients with prostate cancer and explore its related factors.Methods 346 elderly patients with prostate cancer in Wuhan area from May 2013 to May 2014 were chosen as the objects in this study.Nutritional risk screening 2002 was used to evaluate nutritional risk.The sleep quality,anxiety,lower urinary tract symptoms,differentiation and other data of patients were collected.The influencing factors for nutritional risk in the patients were analyzed.Results The ratio of nutritional risk in elderly advanced prostate cancer patients was 35.3％ (122/346).The nutritional risk was increased with age (P＜0.05).The prostate cancer patients with nutritional risk had a higher international prostate symptom score (IPSS) (P＜ 0.05).Monovariate factor analysis showed that sleep quality,operation,pathology staging,radiotherapy,chemotherapy,lower urinary tract symptoms (LUTS) were the impact factors for nutritional status in elderly patients with prostate cancer (P＜0.05).Logistic regression analysis showed that age (OR=0.29),sleep quality (OR=0.25) were the protective factors for the nutritional status,while surgery (OR=12.67),pathological staging (OR=1.65),radiotherapy (OR=2.65),SPSS (OR=1.55),chemotherapy (OR=1.85) were the risk factors for nutritional status (P＜ 0.05).Conclusions The incidence of nutritional risk is high in elderly prostate cancer patients.Age,sleep quality are the protective factors,and operation,pathology staging,SPSS,chemotherapy,and radiotherapy are the risk factors for nutritional status.

Objective:To analyze the effect of traditional Chinese medicine (TCM) non-drug therapy on all-cause mortality and 12-month readmission in patients with chronic heart failure.Methods:A total 824 patients aged (80±10) years with chronic heart failure admitted to 4 hospitals in Shanghai Pudong New Area from January 2016 to December 2019 were retrospectively enrolled. Propensity score match (PSM) method was used and 602 patients (301 pairs) were successively matched into TCM non-drug group (study group) and control group. The basic information, comorbidities, medication, laboratory test results, imaging findings, 12-month readmission and all-cause mortality after discharge were compared between two groups. Cox regression was used to analyze the influencing factors of adverse events in patients with chronic heart failure.Results:After PSM there were no significant differences in baseline variables between study group and control group ( P>0.05). The one-year survival probability of the study group was higher than that of the control group ( P=0.013). The adverse event incidence rate [43.52% ( n=131) vs. 53.82% ( n=162)], all-cause mortality [15.61% ( n=47) vs. 23.59% ( n=71)], 3-month readmission [10.96% ( n=33) vs. 17.61% ( n=53)], 6-month readmission [16.90% ( n=51) vs. 24.25% ( n=73s)], cardiac function classification, hs-CRP and NT-proBNP levels in study group were significantly lower than those in control group (all P<0.05). The Cox proportional risk model showed that old age ( RR=1.018, P<0.01), decreased cardiac function ( RR=2.200, P<0.01), diabetes ( RR=1.340, P=0.04), NT-proBNP≥7 900 ng/L( RR=1.557, P=0.01) were risk factors, while TCM non-drug therapy ( RR=0.768, P=0.04) was protective factor for the occurrence of adverse events. Conclusion:TCM non-drug therapy has a protective role for the occurrence of adverse events in patients with chronic heart failure. The use of TCM non-drug therapy should be advocated to improve the prognosis of patients, particularly at grassroots level.

Objective:To observe the effect of herbal-partitioned moxibustion (HPM) on pain-related behavior and emotion in a rat model of chronic inflammatory visceral pain, and to investigate the mechanism.
Methods:Twenty-four male Sprague-Dawley (SD) rats were randomly divided into three groups:a normal group, a model group and an HPM group. Except for the normal group, rats in the other two groups were clystered with mixed liquor of Trinitrobenzene Sulfonic Acid (TNBS) and 50%ethanol to induce the chronic inflammatory visceral pain model. After the models were established successfully, rats in the HPM group were treated with HPM at bilateral Tianshu (ST 25) and Qihai (CV 6). Rats in the normal group and the model group were only fixed as those in the HPM group without treatment. Abdominal withdrawal reflex (AWR) score, mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were adopted to detect the visceral and somatic pain;meanwhile, open field test (OFT) and elevated plus maze test (EPMT) were employed to evaluate pain emotions such as depression and anxiety.
Results:Compared with the normal group, AWR scores of the model group were significantly increased under different stimulus expansion pressure level (P<0.01), MWT and TWL were significantly decreased (P<0.05);in OFT, the values of horizontal activities and vertical activities were significantly decreased (P<0.01);in EPMT, the proportion of the number of entry into the open arms (OE%) and that of residence time in the open arms (OT%) significantly decreased (P<0.01), indicating that the model was successful. Compared with the model group, the AWR score of the HPM group was decreased significantly (P<0.05), MWT and TWL were significantly increased (P<0.05), the values of horizontal activities and vertical activities in the model group were significantly increased (P<0.01);in OFT and EPMT, OE%and OT%were significantly increased (P<0.01).
Conclusion:HPM has analgesic effect on chronic inflammatory visceral pain. It can reduce the visceral and somatic pain in rats and markedly improve the emotions such as anxiety and depression induced by chronic visceral pain.

Objective:To observethe influence of electroacupuncture (EA) on histomorphologies of lacrimal glands, cornea and conjunctiva in experimental dry eye syndrome, and to explore the repair effects of EA on lacrimal glands and ocular surface damage. Methods:Twenty-four healthy male New Zealand rabbits were randomly divided into a normal group, a model group, an EA group and a medication group, 6 rabbits in each group. Experimental dry eye syndrome models were prepared in rabbits by using 0.1% benzalkonium chloride for eye drops. Tear secretion volume, break-up time of tear film (BUT) and corneal fluorescein staining score were observed before and after the treatment. Periodic acid Schiff (PAS) staining method was used to observe the changes of conjunctival goblet cells in rabbits. After hematoxylin eosin (HE) staining, morphological changes of rabbit cornea, conjunctiva and lacrimal gland tissues were observed under light microscope. Results: Compared with the normal group, tear secretion volume and BUT were significantly reduced (bothP<0.01), while the corneal fluorescein staining score was significantly increased (P<0.01) in the model group. Compared with the model group, tear secretion volume and BUT were significantly increased, while the corneal fluorescein staining score was significantly decreased in the EA group and the medication group (allP<0.01). Compared with the normal group, the number of conjunctival goblet cells in the model group was significantly reduced; compared with the model group, the numbers of conjunctival goblet cells were all relatively higher in the EA group and the medication group. Pathological lesions of cornea, conjunctiva and lacrimal glands all showed improvement by HE staining in the EA group and the medication group after the intervention. Conclusion:EA can improve tear secretion and tear film stability of rabbit dry eye syndrome, and repair the pathologic lesions of conjunctival goblet cells, corneal epithelia, cornea, conjunctiva and lacrimal glands.

Objective To master the iodine nutritional status of residents and to evaluate the effect of iodine nutrition improvement on residents health after the adjustment of salt iodine concentration. Methods According to the method of population proportion sampling, 30 county-level monitoring sites were selected in 2014, a primary school was selected from each county (city, district) by the method of simple random sampling and 50 students aged 8 - 10 (half males and half females) were selected in each school, B ultrasound was used to detect thyroid volume, arsenic cerium catalytic spectrophotometry (WS/T 107-2006) was used to detect urinary iodine, direct titration was used to detect salt iodine; At the same time, 20 pregnant women were selected from each town and urinary iodine was determined. All results were compared with the results of 2011 to evaluate the effect of iodine nutrition improvement on resident's health after the adjustment of salt iodine concentration. Results A total of 1 437 edible salt samples were tested, the median of salt iodine concentration was 24.1 mg/kg. Based on the new standard (18 - 33 mg/kg), the coverage rate of iodized salt was 95.4%(1 371/1 437), the qualified rate of iodized salt was 80.3%(1 101/1 371), the consumption rate of qualified iodized salt was 76.6% (1 101/1 437). A total of 1 496 urine samples of children and 630 urine samples of pregnant women were tested, the median of urinary iodine of children and pregnant women was 224.6 and 177.1 μg/L, respectively, which were significantly lower than those of 2011 (274.6, 279.6μg/L), the differences were statistically significant (H=70.10, 153.50, all P<0.05). The proportion of counties which iodine nutrition of children and pregnant women in suitable range was 36.7% (11/30) and 56.7% (17/30), which were higher than those of 2011 [6.5%(2/31), 25.8%(8/31)], the differences were statistically significant (χ2 = 7.88, 5.00, all P < 0.05). Totally 1 552 children were examined thyroid in Shanxi Province, the rate of goiter was 4.4% (69/1 552). Conclusion The new standard of iodine concentration makes it possible to maintain a sustainable elimination of iodine deficiency disorders, and it can improve the iodine nutrition of children aged 8-10 years and pregnant women to more reasonable level.

Deep brain disease stimulation (DBS) is commonly used to treat movement disorders such as Parkinson disease,and current evidence suggests that DBS may also be useful for refractory epilepsy and is affected by a variety of factors.Studies show that stimulation of the anterior nucleus of the thalamus and hippocampus may decrease the frequency of refractory seizures.The efficacy of stimulating other targets remains inconclusive.An absence of structural abnormality on imaging and electrode position are associated with stimulation efficacy.Certain seizure types may respond more favorably to specific targets.There are several factors that potentially predict seizure outcome following DBS,but more large-scale clinical trials are needed.
