ObjectiveTo investigate the value of proton magnetic resonance spectroscopy (1H-MRS), gradient dual-echo, and triple-echo sequences in the quantitative evaluation of treatment effect of fatty liver at 3.0T MR.MethodsThirty patients with fatty liver diagnosed by CT or ultrasound who admitted in Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital between August 2017 and May 2018, were enrolled and undergone gradient dual-echo, triple-echo, and 1H-MRS examination before and 3 months after treatment. The fat index (FI) and relative lipid content (RLC) were measured. Fatty liver index (FLI) was calculated from blood biochemical indicators, waist circumference, and BMI at the same time. With the reference standard of FLI, the results before and after treatment measured from MRI were analyzed.ResultsThere were significantly differences of FLI, FIdual, FItriple, and RLC before and after treatment (t=5.281, P<0.001; Z=–3.651, P<0.001; Z=–3.630, P<0.001; Z=–4.762, P<0.001), all indexes decreased after treatment. FIdual and FItriple were positively correlated with FLI before (rs=0.413, P=0.023; rs=0.396, P=0.030) and after treatment (rs=0.395, P=0.031; rs=0.519, P=0.003), the highest correlation factor was FItriple to FLI after treatment. There were no significant correlation between RLC and FLI before and after treatment (P>0.05).ConclusionsIt is feasible to quantitatively evaluate the treatment effect of fatty liver by using 1H-MRS, gradient dual-echo, and triple-echo sequences. Gradient triple-echo sequences has better accuracy, which is technically easy to implement and more suitable for clinical development.
Objective To summarize our experience on leaflet extension in reoperation after tricuspid valve repair in children at age≤15 years and to explore the application indicators and skills of this technique. Methods We retrospectively analyzed the clinical data of 23 children who underwent reoperation after tricuspid valve repair in Xinhua Hospital between January 2006 and October 2015. There were 15 males and 8 females with a mean age of 8.7 years, ranging from 5 to 15 years. The leaflet was extended by artificial pericardium patch. After surgery, warfarin anticoagulation therapy was done, and international normalized ratio was maintained 2.0 to 3.0. Results The average cardiopulmonary bypass time was 87-132 (98.5±35.7) minutes, and average aortic cross-clamping time was 56-97 (68.40±23.78) minutes. One patient died in hospital. There were 3 patients with complications including respiratory failure in 1 patient, acute renal failure in 1 patient, and right heart insufficiency in 1 patient. All the children cured and were followed up for 5 months to 10 years, with a mean follow-up of 3.5 years. One patient died during the follow-up. Six patients suffered mild to moderate tricuspid regurgitation and tricuspid valve function of the rest patients was good. No other redo-valve surgery or complications correlated to anticoagulation occurred. Conclusion Leaflet extension in reoperation after tricuspid valve repair in children is useful with optimistic middle to long term efficacy and needs intensive care therapy during the perioperative period.
ObjectiveTo investigate the efficacy of macrolide antibiotics on patients with lower respiratory tract infection. MethodsA total of 146 patients with lower respiratory tract infections were selected from January 2011 to January 2014 in the Department of Respiratory Medicine of our hospital and divided into low risk and high risk group. Based on the clinical characteristics of the patients, low risk treatment plan was erythromycin capsule 0.25 g once, 3 times/day plus compound liquorice mixture, followed by clarithromycin 0.25 g once, 2-3 times/day plus compound liquorice mixture or clarithromycin 0.25 g once, 2-3 times/day plus compound liquorice mixture; high risk group treatment was macrolide antibiotics (erythromycin, clarithromycin) 0.25 g once, 3 times/day and second generation cephalosporins (cefaclor or cefuroxime) 0.25 g once, 3 times/day plus compound liquorice decoction. ResultsThe clinical seven-day curing rate was 54.1%, and the total effective rate was 93.1%. For low risk treatment regimen, the sevenday curing rate was 63.6%, and the total effective rate was 94.9%; for high risk treatment regimen, the seven-day curing rate was 34.0%, and the total effective rate was 89.4%. Acute bronchitis had high curing rate which was 70.1%. ConclusionMacrolide antibiotics (erythromycin, clarithromycin) oral administration in the treatment of lower respiratory tract infection is reliable and effective, which is worth promoting in clinical application.
ObjectiveTo observe the clinical effect of vitrectomy with internal limiting membrane peeling and air tamponade in the treatment of idiopathic macular hole (IMH).MethodsA prospective, non-randomized controlled case cohort study. Twenty eyes of 20 patients with IMH in Ophthamology Department of The Second Hospital of Jilin University from September 2016 to January 2017 were included in this study. There were 4 males (4 eyes) and 16 females (16 eyes), with the mean age of 60.60±9.50 years and the mean disease course of 9.55±15.5 months. The stage of macular hole ranged from Ⅱ to Ⅳ. All patients underwent BCVA, intraocular pressure, spectral-domain OCT (SD-OCT) and multifocal ERG examinations. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. The minimum diameter (MIN), bottom diameter (BD), height (H), the defective diameter of ellipsoid zone, the defective diameter of external limiting membrane (ELM) of the macular hole were measured by SD-OCT (German Heidelberg). Then the macular hole index (MHI=H/BD), hole traction index (THI=MD/BD) and hole diameter index (DHI=H/MD) were calculated. The response density in P1 wave was detected by mf-ERG. The logMAR BCVA was 1.18±0.54. There were 5 eyes with less than 400 μm MIN, 13 eyes with 400-700 μm MIN and 2 eyes with over than 700 μm MIN. All the patients were underwent vitrectomy with internal limiting membrane peeling and air tamponade. According to the SD-OCT image features after surgery, IMH closure was divided into type Ⅰ closed, type Ⅱ closed and unclosed. The follow-up was equal or greater than 3 months. The closure rate of IMH, BCVA and the changes of microstructure parameters of macular area were observed. Spearman correlation analysis was used to analyze the correlation between BCVA and the wave response density in P1 before surgery and the efficacy after IMH surgery.ResultsClosure rate of IMH: 18 eyes (90.0%) were completely closed (all type Ⅰ closed). The closure rate of macular hole with the MIN less than 400 μm was 100.0% (5/5), 400-700 μm was 92.3% (12/13), and over than 700 μm was 50% (1/2). BCVA: the mean logMAR BCVA at 1 week, 1 month, 3 months after surgery were 0.83±0.54, 0.65±0.41, 0.48±0.34, and there was statistically significant difference between preoperative and postoperative BCVA (t=3.382, 4.459, 5.250; P=0.003, 0.007, 0.004). The outcomes of SD-OCT at 3 months after surgery: 18 eyes (90.0%) with intact ELM. The defective diameter of ellipsoid zone was 260.34±272.08 μm, there was statistically significant difference between before and after surgery (t=13.545, P=0.002). The outcomes of mf-ERG: the P1 wave response density of the ring 1 and ring 2 after surgery were increased compared with before surgery (t=-16.748, -6.151; P＜0.01,＜0.01). The results of Spearman correlation analysis: there was a positive correlation between postoperative BCVA and preoperative MIN, the defective diameter of ellipsoid zone and ELM, and postoperative the defective diameter of ellipsoid zone (r=0.56, 0.59, 0.68, 0.52; P=0.010, 0.006, 0.001, 0.019). The postoperative BCVA was negatively correlated with the P1 wave response density of ring 1 and ring 2 of mf-ERG (r=－0.34, －0.16; P=0.006, 0.020). The IMH closure had a significant negative correlation with MIN and the defective diameter of ELM (r=－0.449, －0.449; P=0.047, 0.047). MHI and THI were positively correlated with the closure of the hole (r=0.474, 0.546; P=0.035, 0.013). Intraocular pressure increased in 2 eyes during the follow-up period, and returned to normal within 1 week after the administration of antihypertensive drugs. There were no complications during or after the operation.ConclusionsVitrectomy with internal limiting membrane peeling and air tamponade in the treatment of IMH is safe and effective. The MIN, MHI THI are significantly correlated with the curative effect after IMH surgery, which could be used as the index to predict and evaluate the curative effect. The response density of ring 1 and ring 2 in P1 wave of mf-ERG is signifi-cantly improved compared with before surgery, and which is negatively correlated with BCVA.
ObjectiveTo analyze the effect of anal fistula clip (AFC) in the treatment of anal fistula, and to evaluate its safety. MethodsA historical cohort study method was conducted. Eighty-three patients with glandular transsphincteric anal fistula in the Xuzhou Central Hospital from September 2018 to May 2021 were collected, of which 42 patients underwent the AFC treatment (AFC group), 41 patients underwent the endorectal advancement flap (ERAF) treatment (ERAF group). The operation time, intraoperative blood loss, visual analogue scale (VAS) score of anus pain on postoperative day 1, 3, and 7, wound healing time, Wexner incontinence score of anal function on postoperative month 6, and clinical efficacy (healing and failure) were compared between the two groups. ResultsThe operation was successfully completed in both groups. The operation time and intraoperative blood loss in the AFC group were shorter or less than those in the ERAF group (P<0.05). No complications such as internal opening infection and bleeding occurred in the two groups. There were no statistical differences in the VAS score of postoperative anus pain at all time point between the two groups (P>0.05). The median follow-up time was 22 months. There was no statistical difference in the wound healing time between the two groups (P>0.05). The Wexner score of anal function in the AFC group was lower than that in the ERAF group (P<0.05), and there was no statistical difference between after operation and before operation (Z=–1.751, P=0.089) in the AFC group, while that in the ERAF group after operation was higher than before operation (Z=–1.859, P=0.014). The healing rate had no statistical difference between the AFC group and ERAF group (85.7% versus 77.5%, χ2=0.925, P=0.336). Conclusion From the results of this study, the AFC is safe and effective in treatment of anal fistula, with the advantages of relatively simple operation, less bleeding during operation, lighter postoperative pain, and good protection of anal function.
Objective A meta-analysis was performed for a comparison of outcomes between surgery and balloon angioplasty (BA) for native coarctation of the aorta (NCA) in pediatric patients. Methods Electronic databases, including PubMed, EMbase, Medline, Cochrane Library, Weipu Data, Wanfang Data and CNKI were searched systematically for the literature aimed mainly at comparing the therapeutic effects for NCA administrated by surgery and BA. Corresponding data sets were extracted and two reviewers independently assessed the methodological quality. Results Ten studies meeting the inclusion criteria were included, involving a total of 723 subjects. It was observed that compared with BA, surgery was significantly associated with a lower incidence of recoarctation (OR, 0.43; 95%CI, 0.30–0.63; P<0.001), repeat intervention due to recoarctation (OR, 0.40; 95%CI, 0.27–0.61;P<0.001) and lower residual transcoarctation gradient in mid to long term follow up (WMD –0.85; 95%CI, –12.34 to –3.76;P<0.001). Compared with BA, surgery was significantly associated with a longer hospitalization time (WMD, 19.40; 95%CI, 15.82–22.99;P<0.001). Incidence of aneurysm formation (OR, 0.64; 95%CI, 0.26–1.57;P=0.33), complications(OR, 1.77; 95%CI, 0.95–3.28; P=0.07), perioperative mortality (OR, 2.57; 95%CI, 0.87–7.61, P=0.09) and immediate transcoarctation residual gradient (WMD –1.66; 95%CI, –4.23–0.90; P=0.2) were not statistically different between surgery and BA. Conclusions Compared with BA, surgery was significantly associated with a lower incidence of recoarctation, repeat intervention due to re-CoA and residual transcoarctation gradient in mid to long term follow up. On the contrary, BA was significantly associated with a shorter hospitalization time. Incidence of aneurysm formation, perioperative mortality, complications and immediate transcoarctation residual gradient were similar between surgery and BA.
