Objective Evaluation of the effect ofYidanshu capsule combined with pancreatic duct jejunum anastomosis (Frey procedure) for elderly chronic pancreatitis with pancreatic duct dilatation.Methods A total of 84 patients with dysphagia after stroke who met the inclusion criteria were divided into 2 groups, 42 in each. Both groups were treated with frey procedure, and the observation group addedYidanshu capsule. Izbicki grading system was used to evaluate patients' clinical symptoms, the EORTC-QLQ-C30 scoring system to evaluate patients' quality of life. The serum levels of inflammatory cytokines was also used to evaluate the clinical efficacy. Results The total effective rate of observation group was 92.8% (39/42), and the control group was 76.2% (32/42). The difference was statistically significant (Z=3.561,P=3.561). After treatment, abdominal pain (0.4 ± 0.1 vs. 1.3 ± 0.2,t=3.672), nausea and vomiting (0.3 ± 0.0vs. 1.0 ± 0.1,t=4.001), Abdominal distension (1.2 ± 0.1vs. 2.0 ± 0.2,t=3.752), weak (0.4 ± 0.1vs. 1.4 ± 0.1,t=4.282) scores in the observation group were significantly lower than the control group (P<0.05). The role function (87.4 ± 9.1vs.70.6 ± 7.0,t=3.459), the body function (70.5 ± 7.2vs. 61.5 ± 6.2,t=4.316), emotional function (79.1 ± 7.7vs. 65.8 ± 6.3,t=3.671), social function (80.3 ± 8.1vs. 69.1 ± 6.2,t=3.773) scores in the observation group were significantly higher than the control group (P<0.05). The serum TNF-α (0.71 ± 0.13 ng/mlvs. 1.02 ± 0.15 ng/ml,t=3.652), IL-8 (1.94 ± 0.1 ng/mlvs. 4.51 ± 0.54 ng/ml,t=3.367), hs-CRP (1.01 ± 0.14 mg/Lvs.2.15 ± 0.29 mg/L,t=3.701) levels in the observation group were significantly lower than the control group (P<0.05).Conclusions TheYidanshu capsule combined with pancreatic duct jejunum anastomosis can improve the clinical curative effect of elderly patients with chronic pancreatitis with pancreatic duct expansion, relieve the clinical symptoms and inflammation, and improve the quality of life.

OBJECTIVETo investigate the operation timing of newborns with rectosigmoid Hirschsprung's disease (HD).

METHODSFrom March 2013 to September 2015, 35 newborns diagnosed as rectosigmoid HD in our department were prospectively and randomly divided into 2 groups: less than 3 months treatment group (18 cases) and more than 3 months treatment group (17 cases, conservative treatment for 3 months). They all underwent laparoscopic-assisted transanal endorectal pull-through (LATEP) (modified Soave) procedure. Clinical data, perioperative conditions, postoperative complication, postoperative anal function evaluated by Wingspread score and barium enema were compared between two groups.

RESULTSThe baseline data of two groups were comparable (all P>0.05). All the cases completed single-stage LATEP procedure successfully without conversion to open operation. Compared with more than 3 months treatment group, preoperative bowel preparation time and operation time were significantly shorter [(6.2±3.3) vs. (9.3±4.1) days, P=0.042; (95±15) vs.(121±23) minutes, P=0.029, respectively], intra-operative blood loss was significantly less [(13±3) ml vs. (22±5) ml, P=0.036], length of resected bowel was significantly shorter [(16±5) cm vs.(23±8) cm, P=0.033], and bowel movement recovery time, parenteral nutrition time, hospital stay were also significantly shorter [(2.3±0.5) vs. (2.9±0.6) days, P=0.046; (5.1±2.1) vs. (5.9±2.3) days, P=0.048; (12.9±3.3) vs. (15.8±4.3) days, P=0.049, respectively] in less than 3 months treatment group. No short-term complications, such as anastomotic leak, interlayer infection and abdominal infection occurred in both groups. The follow-up period ranged from 2 months to 24 months. Only the incidence of perianal excoriation was significantly higher in less than 3 months treatment group compared with more than 3 months treatment group [50.0%(9/18) vs. 23.5%(4/17), P=0.045]. Wingspread score results at 6 and 12 months after operation showed excellent rate of postoperative anal function, which was not significantly different between two groups[ <3 months group : 81.3%(13/16) and 92.9%(13/14); >3 months group: 85.7%(12/14) and 92.3%(12/13), all P>0.05]. Postoperative barium enema results at 6 and 12 months after operation all showed normal shape of colon without residue of barium.

CONCLUSIONSFor newborns with rectosigmoid HD, single-stage definitive operation performed at the age less than 3 months has the advantages of shorter preoperative preparation time, less operating injury, shorter resected bowel, and faster postoperative recovery as compared to the age more than 3 months. If rectosigmoid HD is definitively diagnosed, early operation is suggested to perform at the age less than 3 months.

Objective:To evaluate the application value of left ventricular pressure-strain loop (PSL) in patients with rheumatoid arthritis (RA) by the PSL.Methods:From April 2020 to June 2021, 75 RA patients(case group) and 35 healthy physical examination person(control group) were selected from the Affiliated Hospital of Inner Mongolia Medical University.According to the disease activity scores 28(DAS28) joint disease range of activity score, the patients were divided into low range of activity group (16 cases), medium range of activity group (35 cases) and high range of activity group (24 cases). Echocardiographic examinations were performed on all patients, conventional ultrasound data were collected and the left ventricular PSL technology was used to analyze the myocardial work parameters, including global work index (GWI), global constructive work (GCW), global waste work (GWW) and global work efficiency (GWE). The mean values of myocardial work index (MWI), constructive work (CW), waste work (WW) and work efficiency (WE) were calculated. The differences of myocardial work parameters between the case groups and the control group were compared, and the correlation analysis of myocardial work parameters with global longitudinal strain of left ventricle(LVGLS), left ventricular ejection fraction(LVEF) and DAS28 scores were conducted.Results:①There were no statistically significant differences of clinical data between each case group and the control group (all P>0.05). ②Compared with the control group and low disease activity group, the LVGLS of medium and high disease activity groups decreased obviously (all P<0.05). ③The GWI and GCW of the medium and high disease activity groups were significantly lower than those of the control group (all P<0.05), and there were no statistically significant differences of GWW and GWE between the case groups and the control group (all P>0.05). The mid-segment MWI, apical MWI and CW of the medium and high disease activity case groups, and the mid-segment CW of the medium disease activity case group were lower than those of the control group (all P<0.05). ④In the case group, GWI, GCW and LVEF were significantly and positively correlated ( rs1=0.253, P=0.008; rs2=0.261, P=0.024), and were significantly negatively correlated with LVGLS ( rs1=-0.525, P<0.001; rs2=0.455, P<0.001). There were no significant correlations between myocardial work parameters and DAS28 score (all P>0.05). Conclusions:PSL can early reflect to the impaired cardiac function of RA patients with moderate and high disease activity, and provide a new imaging method for clinical evaluation of the cardiac function of patients.

Objective:To evaluate the cardiac function and systolic dyssynchrony of fetuses exposed to maternal autoimmune antibodies (anti-SSA/Ro60, anti-SSA/Ro52 and anti-SSB/La) by using two-dimensional speckle tracking imaging (2D-STI).Methods:A total of 52 pregnant women with singleton pregnancy in the Affiliated Hospital of Inner Mongolia Medical University from July 2018 to November 2020 were selected. Eighteen fetuses of mothers with autoimmune antibodies were enrolled as autoimmune disease (AD) group and 34 fetuses of healthy mothers without antibodies were included as control group. Maternal baseline characteristics, fetoplacental Doppler parameters, and conventional echocardiographic data of two groups were prospectively collected. The systolic global and regional longitudinal strain of left and right ventricles (LV and RV) and the time to peak strain of regional myocardium were measured using 2D-STI. The differences in time to peak strain between the LV free wall and RV free wall (two-chamber dyssynchrony, 2C-DYS) and between the septum and LV free wall (one-chamber dyssynchrony, 1C-DYS) were also calculated.Results:There were no significant differences between the two groups in conventional systolic and diastolic functional parameters for the LV and RV(all P>0.05). The myocardial deformation parameters and 2C-DYS obtained by 2D-STI showed no statistical differences between two groups(all P>0.05). However, 1C-DYS was significantly more prolonged in the AD group than control group[28.50(13.50, 39.25)ms vs 19.50(8.00, 29.25)ms, P=0.042]. Conclusions:LV systolic mechanical dyssynchrony in fetuses of mothers with autoimmune antibodies suggests in-utero subclinical damage of the cardiac conduction system.

Objective:To observe the feasibility of evaluating right ventricular (RV) function by the method based on left ventricle (LV) pressure-strain ring (PSL) technique in patients with systemic lupus erythematosus (SLE), and to evaluate the efficacy of non-invasive PSL in the diagnosis of dysfunction of both LV and RV.Methods:Thirty-nine patients were enrolled with SLE who were admitted to the Affiliated Hospital of Inner Mongolia Medical University from March 2020 to September 2021 and 57 sex- and age-matched healthy controls underwent assessment by conventional echocardiography, two-dimensional speckle tracking imaging (2D-STI) and myocardial work (MW). The echocardiographic parameters were compared between the groups. The correlations between RVMW parameters and conventional echocardiographic parameters, and between MW parameters and SLEDAI-2K score were analyzed by Spearman correlation analysis.Results:①The two groups did not show any difference at the conventional echocardiographic parameters of the LV systolic function ( P>0.05). In the SLE group, tricuspid regurgitation maximal velocity (TR V max) and right ventricular index of myocardial performance (RIMP) increased, tricuspid annular plane systolic excursion (TAPSE) and tricuspid annular S′ (S′ tv) decreased (all P<0.05), and others did not show statistical difference (all P>0.05). ②The 2D-STI parameters: There were no significant differences in left ventricular global longitudinal strain (LV GLS) ( P>0.05), however RVGLS decreased ( P<0.05). ③The MW parameters of LV and RV: including global constructive work (GCW), global work index (GWI), global wasted work (GWW), and global work efficiency (GWE). In SLE group, LV GWE, RV GWE decreased and LV GWW, RV GWW increased ( P<0.05), others were no significant differences ( P>0.05). ④The correlation analysis: RV GWI positively correlated with TR V max ( rs=0.481). RV GCW positively correlated with TR V max ( rs=0.587). RV GWW positively correlated with right atrial area (RAA) and TR V max ( rs=0.429, 0.610), negatively correlated with S′ tv ( rs=-0.342). RV GWE positively correlated with S′ tv ( rs=0.326) and negatively correlated with RAA ( rs=-0.462) (all P<0.05). SLEDAI-2K score was negatively correlated with LV GLS ( rs=-0.333) and LV GWI ( rs=-0.326) ( P<0.05). Conclusions:The study has shown the impaired systolic function of both LV and RV in patients with SLE. PSL technique, especially RVMV based on LV PSL technique might emerged as a novel measure to evaluate systolic dysfunction in SLE patients.

Objective To evaluate the effect of intrathecal oxytocin on neuropathic pain in rats.Methods Thirty-six SPF male Sprague-Dawley rats,aged 4-6 weeks,weighing 100-150 g,were divided into 4 groups (n =9 each) using a random number table:control group (group C),neuropathic pain group (group NP),neuropathic pain plus normal saline group (group NPN) and neuropathic pain plus oxytocin group (group NPO).The neuropathic pain model was made by partial sciatic nerve injury in NP,NPN and NPO groups.In group NPO,oxytocin l0 μl (0.1 μg) was intrathecally injected on the day of establishing the model and 1 and 2 days after establishing the model,and then normal saline 10 μl was given for tube sealing at 9 a.m.and 4 p.m.every day.In group NPN,normal saline 20 μl was given for tube sealing at the corresponding time points.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 1 day before establishing the model and 1,2,3,4,5,6 and 7 days after establishing the model.The expression of the astrocyte marker glial fibrillary acidic protein (GFAP) and a specific marker of microglia ionized calcium-binding adaptor molecule 1 (IBa-1) was detected by Western blot at 1 day before establishing the model and 3 and 7 days after establishing the model.Results Compared with group C,the MWT was significantly decreased,TWL was shortened and the expression of GFAP and IBa-1 was up-regulated at each time point in NP and NPN groups (P＜0.05).There was no significant difference in MWT,TWL GFAP and IBa-1 at each time point between group NPN and group NP (P＞0.05).Compared with NP group,MWT was significantly increased at 2-4 days after establishing the model,TWL was prolonged at 1-4 days after establishing the model,the expression of IBa-1 was down-regulated on 3 days after establishing the model,and the expression of GFAP was downregulated on 3 and 7 days after establishing the model in group NPO (P＜0.05).Conclusion Oxytocin can reduce neuropathic pain,and the mechanism may be related to inhibiting activation of glial cells in the spinal cord of rats.
