OBJECTIVES: To determine the pharmacological impact of hesperidin, the main component of Citri Reticulatae Pericarpium, on depressive behavior and elucidate the mechanism by which hesperidin treats depression, focusing on the gut-brain axis. METHODS: Fifty-four Sprague Dawley male rats were randomly allocated to 6 groups using a random number table, including control, model, hesperidin, probiotics, fluoxetine, and Citri Reticulatae Pericarpium groups. Except for the control group, rats in the remaining 5 groups were challenged with chronic unpredictable mild stress (CUMS) for 21 days and housed in single cages. The sucrose preference test (SPT), immobility time in the forced swim test (FST), and number in the open field test (OFT) were performed to measure the behavioral changes in the rats. Enzyme-linked immunosorbent assay was used to determine the levels of 5-hydroxytryptamine (5-HT) and brain-derived neurotrophic factor (BDNF) in brain tissue, and the histopathology was performed to evaluate the changes of colon tissue, together with sequencing of the V3-V4 regions of 16S rRNA gene on feces to explore the changes of intestinal flora in the rats. RESULTS: Compared to the control group, the rats in the model group showed notable reductions in body weight, SPF, and number in OFT (P<0.01). Hesperidin was found to ameliorate depression induced by CUMS, as seen by improvements in body weight, SPT, immobility time in FST, and number in OFT (P<0.05 or P<0.01). Regarding neurotransmitters, it was found that at a dose of 50 mg/kg hesperidin treatment upregulated the levels of 5-HT and BDNF in depressed rats (P<0.05). Compared to the control group, the colon tissue of the model group exhibited greater inflammatory cell infiltration, with markedly reduced numbers of goblet cells and crypts and were significantly improved following treatment with hesperidin. Simultaneously, the administration of hesperidin demonstrated a positive impact on the gut microbiome of rats treated with CUMS, such as Shannon index increased and Simpson index decreased (P<0.01), while the abundance of Pseudomonadota and Bacteroidota increased in the hesperidin-treated group (P<0.05). CONCLUSION The mechanism responsible for the beneficial effects of hesperidin on depressive behavior in rats may be related to inhibition of the expressions of BDNF and 5-HT and preservation of the gut microbiota.

OBJECTIVETo investigate the risk factors on initial surgery in Crohn's disease.

METHODSThe clinical data of 173 patients with Crohn's disease who were treated during 2010 and 2014 years in the Second Affiliated Hospital of Sun Yat-Sen University, were analyzed retrospectively. The patients who had received intestinal resection or whose initial symptoms occurred at least 5 years at the end of the follow-up were recruited. Montreal classification was used to evaluate lesion location and disease behavior. The risk factors of the initial surgery were analyzed by using Logistic regression model.

RESULTSEighty-five patients (49.1%) received intestinal resection in 5 years after the onset of symptoms. The result of univariate analysis showed that the probability of surgical treatment is high in patients who were male and those older than 40 years at diagnosis (P<0.05). Lesions involving upper digestive tract, stenosis and penetrating lesions were also the risk factors on initial surgery in Crohn's disease (P<0.05). The result of multivariate analysis showed the relative risk of initial surgery was increased in male gender (OR=2.02, 95%CI:1.04-3.92) and in those who were older than 40 years at diagnosis (OR=2.34,95%CI:1.05-5.22). However, in patients with Crohn's disease involving colon alone, the relative risk of initial surgery was decreased (OR=0.35, 95%CI:0.13-0.97).

CONCLUSIONAbdominal pain is the most common clinical presentation in Crohn's disease. Disease behavior and operation is closely related. Older than 40 years at diagnosis and male gender is high risk factor for surgery while colonic lesion alone is protective factor.

Objective:To discuss the influence of bifid triple viable enteric-coated capsules on liver function and inflammatory fac-tor in the patients with non-alcoholic steatohepatitis ( NASH) . Methods:Totally 70 cases of patients with NASH were selected and di-vided into the control group and the observation group at random. The patients in the two groups were all given routine hepatoprotective therapy. The patients in the observation group were additionally given 420mg bifid triple viable enteric-coated capsules, three times a day for 4 weeks. Except for bifid triple viable enteric-coated capsules, the patients in the control group were given the same medical treatment as that in the observation group. The changes of liver function index, serum high sensitivity C reaction protein ( hs-CRP) , IL-6 and IL-8 levels in the two groups before and after the medical treatment were observed and the security was compared. Results:After the 4-week medical treatment, ALT, GGT, serum hs-CRP, IL-6 and IL-8 levels in the two groups were obviously declined than those before the treatment (P<0. 05 or P<0. 01), and the declining rate in the observation group was much higher than that in the control group (P<0. 05). Totally 6 and 4 cases of adverse drug reaction (ADR) respectively appeared in the observation group and the control group during the medical treatment with mild symptom, and the difference was without statistical significance (P>0. 05). Conclusion:Bifid triple viable enteric-coated capsules in the treatment of NASH can obviously reduce the serum hs-CRP, IL-6 and IL-8 levels, inhibit the intrahepatic inflammation and immunologic injury, and improve the liver function index with high security.

Objective To evaluate the therapeutic methods for stones in congenital anomalous kidneys. Methods The clinical outcomes of 126 patients(75 males and 51 females: mean age 39 years, range 12-66 years)who underwent extracorporeal shock wave lithotripsy (ESWL, n= 37), minimally invasive percutaneous nephrolithotomy (MPCNL, n = 41) or open surgery (n = 48) were retrospectively reviewed. There were 40 horseshoe kidneys(31.8%), 51 duplex kidneys(40.5%), 35 malrotated kidneys(27.8%). Seventyl calculi were located in left kidneys(55.6%)and 56 in right kid-neys(44.4%). There were 96 single stones(76.2%)and 30 complex stones(23.8%). The greatest di-ameter of stone ranged from0.8 cm to 2.2 cm(mean 1.5 cm) in ESWL group, 1.0 cm to 4.0 cm (mean 2.5 cm) in MPCNL group and 1.5 cm to 3.8 cm(mean 2.7 cm) in open surgery group. The therapeutic effects of 3 methods were compared. Results The stone-free rate at 1 session was 78.4%(29/31) in ESWL group, 85.4%(35/41) in MPCNL group and 87.5%(42/48) in open sur-gery group. No significant difference was found among the 3 groups(x2 = 1.39,P=0.50). The inci-dence of complications was 13.5% in ESWL group, 9.7% in MPCNL group and 6.3% in open sur-gery group(x2=1.28, P=0.53). Only 1 case of malrotated kidney suffered massive hemorrhage and was cured by selective embolism of renal artery. No major complications occurred in the other pa-tients. Conclusions With rigorous indication, ESWL or MPCNL is as safe and effective as open sur-gery in the management of stones in congenital anomalous kidneys. It should be considered as the pri-mary therapy. But the treatment must be individualized in terms of the type anomalous kidney, stone characteristics and obstruction.

Look-up table (LUT) algorithms have been widely used in digital signal processing, but the article on the application of LUT algorithms in digital subtraction angiography was rarely reported. In this article, the effect of different LUT algorithms on digital subtraction angiography images is introduced. The result reveals that different LUT algorithms can bring about different effects of image. Based on analysis and comparison, we deem it possible to acquire improved images of DSA by use of some LUT algorithms with image processing.

Objective The aim of the paper is to investigate the alteration of the physical-chemical properties and disinfection effect of electrolyzed-oxidizing water during storage, and to provide theory support for its application. Methods A typical electrolyzed-oxidizing water was stored under a closed and light condition for 66 days and its physical-chemical parameters and disinfection effect were measured at fixed periods. Results The results showed that the chlorine loss of the electrolyzed-oxidizing water was quite fast and reached 50% and 100% after 10 days and 66 days of storage period respectively, the pH value was quite stable, from 2.5 to 2.47. The oxidation-reduction potential(ORP) of the water decreased slowly only from 1 146 mV to 1 100 mV within 45 day, but decreased rapidly after 45 days of storage. The results also showed that the inactivation of Bacillus subtilis var niger spores by the electrolyzed-oxidizing water also decreased rapidly after one week of storage,from 100%(the first week) to less than 90%(after 10 days). Conclusion The electrolyzed-oxidizing water can keep its strong disinfection effect after 7-10 days of storage. It was believed that the chlorine loss from the electrolyzed-oxidizing water was the main reason for the decrease of its disinfection effect during storage.

OBJECTIVE: To observe the therapeutic effects of the conventional therapy plus Melitracen and Flupentixol in the treatment of functional dyspepsia(FD).METHODS: 320 FD cases were divided into gastrointestinal dyskinesis type(Type A,n=120 cases),ulceration type(Type B,n=100 cases),and nonspecific type(Type C,n=100 cases) based on their clinical symptoms.Patients of different clinical types were randomly assigned to receive conventional therapy alone or in combination with Melitracen and Flupentixol for 4 weeks.The curative effects were observed using gastrointestinal symptom rating scale(GSRS) and the total effective rate were computed.RESULTS: After treatment,the GSRS score of 3 different clinical types of FD in the combination therapy group versus the conventional therapy alone were 1.53?1.68 vs.3.10?1.78,2.02?1.63 vs.3.48?1.80 and 3.46?2.95 vs.5.18?3.21 respectively(P
