Objective To study the effect of electromyographie biofeedback on visceralgia hypersensitivity in patients with refractory irritable bowel syndrome (IBS) and the relationship between psychological factors and vis-ceral hypersensitivity. Methods Sixty patients with refractory IBS were enrolled in this study and received electro-myographic biofeedback treatment for 4 weeks. The threshold of visceralgia, and scores on the Hamilton anxiety rating scale (HAMA) and the Hamilton depression rating scale (HAMD) were evaluated before and after treatment. Re-suits Compared with the baseline values, the threshold of visceralgia increased significantly during treatment(P≤ 0101) and the total scores on both the HAMA and HAMD had declined significantly (P≤0.01) by the end of 4, weeks of treatment. The evolution of the index of the threshold of visceralgia was negatively correlated with the evolu-tion of both the HAMA and HAMD scores (r = -0.543, P≤0.01; r = -0.728,P≤0.01). Conclusion Elec-tromyographic biofeedback treatment can elevate the threshold of visceralgia hypersensitivity in patients with refractory IBS. Anxiety and depression might contribute to visceralgia hypersensitivity in IBS.

Objective:To investigate the clinical efficacy and safety of amisulpride in the treatment of schizophrenia.Methods:Ninety patients with schizophrenia admitted to Quzhou Third Hospital from August 2020 to March 2022 were included in this study. They were randomly divided into an observation group and a control group ( n = 45/group). The control group was treated with olanzapine, and the observation group was treated with amisulpride. All patients were treated for 8 consecutive weeks. Total response rate, Positive and Negative Syndrome Scale score, Clinical Global Impression Scale-Severity of Illness score, glucose and lipid metabolism indicators, Treatment Emergent Symptom Scale score, and adverse reactions were compared between the two groups. Results:Total response rate was 88.89% (40/45) in the control group and 93.33% (42/45) in the observation group. There was no significant difference in total response rate between the two groups ( χ2 = 0.14, P > 0.05). After treatment, the PANSS score [(52.14 ± 3.99) points] and CGI-S score [(3.05 ± 0.86) points] in the observation group were significantly lower than (56.38 ± 4.05) points and (4.34 ± 0.92) points in the control group ( t = 5.00, 6.87, both P < 0.001). The levels of fasting plasma glucose [(5.25 ± 0.33) mmol/L], total cholesterol [(4.08 ± 0.67) mmol/L], triglyceride [(1.29 ± 0.35) mmol/L], and low density lipoprotein-cholesterol [(2.60 ± 0.31) mmol/L] in the observation group were significantly lower compared with the control group [(6.02 ± 0.51) mmol/L, (4.71 ± 0.59) mmol/L, (1.61 ± 0.26) mmol/L, (2.91 ± 0.34) mmol/L, t = 8.50, 3.61, 4.92, 4.52, all P < 0.001]. High density lipoprotein-cholesterol level in the observation group was significantly higher than that in the control group [(1.57 ± 0.36) mmol/L vs. (1.18 ± 0.42) mmol/L t = -4.73, P < 0.001]. Treatment Emergent Symptom Scale score in the observation group was significantly lower than that in the control group [(2.39 ± 0.58) points vs. (2.87 ± 0.62) points, t = 3.79, P < 0.05]. The incidences of drowsiness [6.67% (3/45)], constipation [8.89% (4/45)], and weight gain [2.22% (1/45)] in the observation group were significantly lower than those in the control group [73.33% (33/45), 28.89% (13/45), 17.78% (8/45), χ2 = 4.14, 4.64, 4.44, P < 0.05]. Conclusion:The efficacy of sulfapride in the treatment of schizophrenia is equivalent to that of olanzapine.

Objective:To explore the efficacy of hysteroscopy combined with laparoscopy in the treatment of infertility caused by tubal obstruction (TO) and its effect on sex hormone levels.Methods:According to different surgical methods, 78 infertile patients caused by TO admitted from January 2017 to March 2019 in Zhejiang Xin′an International Hospital were divided into the treatment group (40 cases) and the control group (38 cases). The patients in the treatment group were treated with hysteroscopy combined with laparoscopy, and the patients in the control group were treated with hysteroscopy. The indicators related to the operation, unobstructed fallopian tube and pregnancy in 1 year in the two groups were compared. Serum sex hormones and stress response indicators were measured before and after the operation.Results:The operation time in the treatment group was (45.17 ± 8.76) min, which was significantly longer than that in the control group (34.01 ± 6.25) min, and the difference was statistically significant ( P<0.05). There was no significant differences in intraoperative blood loss, postoperative exhaust time, hospital stay and complication rate between the two groups ( P>0.05). After operation, the levels of serum estradiol (E 2), follicle stimulating hormone (FSH), luteinizing hormone (LH), cortisol (Cor) and hypersensitive C-reactive protein (hs-CRP) in the two groups increased significantly ( P< 0.05), while thyroid stimulating hormone (TSH) levels decreased significantly ( P<0.05). After operation, the levels of Cor and hs-CRP in the treatment group were lower than those in the control group [(22.19 ± 7.32) mg/L vs.(33.05 ± 8.24) mg/L, (7.28 ± 2.63) mg/L vs. (11.89 ± 3.84)mg/L], while the levels of E 2, FSH, LH and TSH in the treatment group were higher than those in the control group [(181.48 ± 21.24) ng/L vs. (136.00 ± 19.56) ng/L, (30.51 ± 5.76) U/L vs. (24.84 ± 6.0) U/L, (34.62 ± 6.57) U/L vs. (29.37 ± 7.25) U/L, (3.12 ± 0.65) mU/L vs. (1.93 ± 0.54) mU/L], and the differences were statistically significant ( P<0.05). The rates of complete patency of fallopian tube and intrauterine pregnancy in 1 year in the treatment group were higher than those in the control group [92.50%(37/40) vs. 76.32%(29/38), 75.00%(30/40) vs. 52.63%(20/38)], and the differences were statistically significant ( P<0.05). Conclusions:Hysteroscopy combined with laparoscopy in the treatment of infertility caused by TO is effective, and can effectively promote the recanalization of fallopian tube, improve the level of sex hormones, reduce the stress response of patients and improve the pregnancy rate.
