ObjectiveTo evaluate visual field changes in early mild Parkinson's disease. Methods A total of 66 eyes of 33 cases with early mild Parkinson's disease and 72 eyes of 36 age-matched normal individuals were enrolled into the study. Humphrey Field Analyzer II was applied for central visual field test. The visual field indices of mean deviation (MD) and pattern standard deviation (PSD) were analyzed to evaluate the location and the characteristics of visual field defect in this study. ResultsVisual field indices MD (-3.4±2.5) dB was significantly changed in patients with PD when compared to the controls (-0.6±1.7) dB. PSD (4.3±2.6) was significantly higher in patients with PD than that in the control group (2.1±1.8) dB. Glaucoma hemifield test (GHT) assessment was within normal limits in the controls. Of the 33 patients (66 eyes) in PD, GHT showed outside normal limits in 31 eyes, borderline in 8 eyes, and within normal limits in 27 eyes. 31 eyes outside normal limits appeared glaucomatous visual field defects, in which 16 with nasal step and 5 with arcuate defect. ConclusionsVisual field indices including MD and PSD in early mild patients with PD were significantly worse than that in the controls group. GHT abnormalities could be found in early mild PD patients with visual field defects, including pericentral scotoma and nasal step, which mimicked glaucomatous changes.
Objective To observe the thickness of the retina, retinal nerve fiber layer (RNFL), choroid and sclera among the difference posterior sclera shape (PSS) in high myopia (HM). Methods Sixty HM patients (96 eyes) were enrolled in this study. There were 18 males (25 eyes) and 42 females (71 eyes). The mean age was (51.32±10.06) years. The mean spherical equivalent was (-14.38±6.31) DS. The mean axial length was (29.49±2.44) mm. The eyes were evaluated from deep range imaging optical coherent tomography (DRI-OCT) Atlantis 3D model, and divided as four groups include PSS-Ⅰ (27 eyes), PSS-Ⅱ (46 eyes), PSS-Ⅲ (11 eyes) and PSS-Ⅸ (12 eyes) according to the Curtin classification method. The thickness of the retina, RNFL, choroid and sclera were measured in the EDTRS Grid area. Results There were statistically significant differences in the thickness of retina of the central, first circle, second circle in the EDTRS Grid area among PSS-Ⅰ, PSS-Ⅱ, PSS-Ⅲ and PSS-Ⅸ groups (F=4.48, 5.03, 4.98; P＜0.01). There was no statistically significant differences in the thickness of RNFL among four groups (F=0.13, P=0.93). There was no statistically significant differences in the central choroidal thickness (F=0.31, P=0.81). There were statistically significant differences in the first circle, second circle choroidal thickness among four groups (F=2.86, 2.96; P=0.04, 0.04). There was no statistically significant differences in the thickness of sclera under macular fovea among four groups (F=0.80, P=0.49). Conlusions There are changes of thickness of the retina, choroid present in the difference EDTRS Grid area among the difference PSS in HM, and changes in PSS-Ⅸ is most obvious.
Objective To evaluate the effect of perioperative fluid management on postoperative pulmonary complications (PPCs) of esophagectomy, and to find out the optimal scheme for perioperative fluid administration. Methods This retrospective cohort study enrolled 75 patients with esophageal squamous cell cancer who have received esophagectomy in West China Hospital from June to December 2014. We used the Kroenke's postoperative pulmonary complications classification system to define the PPCs. Patients with PPCs of grade Ⅱ-Ⅳ were considered as PPCs group (n=13, 12 males, 1 female, age of 64.62±8.64 years), and others were considered as non-complication group (n=62, 50 males, 12 females, age of 60.55±8.73 years). Intraoperative and postoperative fluid inputs and outputs as well as clinical characteristics between groups were compared. Results Between two groups, there was a great difference in postoperative albumin infusion, intraoperative fluid administration [net input, total input, net input/kg, total input/kg, net input/(kg·h) and total input/(kg·h)] and fluid input on the first postoerative 1–3 days (total input and total input/kg). The cutoff value for total input/(kg·h) in operation and total input on the first 1–3 postoerative days was 12.07 ml/(kg·h) and 178.57 ml/kg, respectively. Conclusion The speed of fluid infusion in operation and total input on postoperative 1-3 days are most important influence factors of PPCs. The speed in operation should not exceed 12.07 ml/(kg·h) and the total input on postoperative 1-3 days should not exceed 178.57 ml/kg. Within this range, an appropriate increase in fluid volume can make patients feel better.
Objective To analyze the prognosis and indications of transjugular intrahepatic portosystemic shunt (TIPS) in patients with Budd-Chiari syndrome (BCS). MethodsPatients with primary BCS who received TIPS in the Department of Gastroenterology, West China Hospital of Sichuan University between February 2009 and February 2020 were retrospectively reviewed. The medical history, preoperative imaging, surgical records, and postoperative outpatient follow-up medical records were recorded. The laboratory indexes before and after operation were compared, and the cumulative free from hepatic encephalopathy rate, stent patency rate, and cumulative survive rate were calculated. Cox proportional hazards model was used to analyze the independent risk factors of hepatic encephalopathy, shunt dysfunction and death. Results A total of 48 patients were included. The main indications for TIPS included variceal bleeding (16 cases), refractory ascites (24 cases), and diffuse obstruction of hepatic vein with acute liver function impairment (8 cases). The cumulative 1 year, 2 years and 3 years of free from hepatic encephalopathy rates were 92.3%, 89.2% and 85.3%, respectively. The stent patency rates were 89.7%, 72.2% and 54.8% at postoperative 1 year, 3 years and 5 years, respectively. The cumulative survival rates were 86.0%, 79.5% and 71.4% at postoperative 1 year, 3 years and 5 years, respectively. Conclusion TIPS can achieve good efficacy in patients with BCS, and most patients receive TIPS for portal hypertension complications rather than acute liver function impairment.
Objective To analyze and summarize the clinical characteristics of foreign body incarceration in upper digestive tract, and to explore the risk factors of its complications. Methods The clinical data of patients with foreign bodies in the upper digestive tract treated in the Affiliated Hospital of Zunyi Medical University between January 1, 2012 and December 31, 2021 were retrospectively analyzed, including demographic data, foreign body type, incarceration site, incarceration time, causes, symptoms, treatment methods and complications of foreign body incarceration. Logistic regression analysis was used to explore the risk factors of complications. Results A total of 721 patients were finally included, ranging in age from 3 months to 90 years old, with an average age of 26.76 years. The proportion of foreign bodies in the upper digestive tract in patients ≤14 years old was the highest (51.18%), and the duration of foreign body incarceration<12 hours was the highest (55.34%). The most common sharp foreign bodies in the upper digestive tract were animal bones (228 cases), and the most common round shaped foreign bodies were coins (223 cases). The most common impaction site was the upper esophageal segment (85.02%). 105 patients (14.56%) had complications, and perforation was the most common (5.55%). Logistic regression analysis showed that age [odds ratio (OR)=0.523, 95% confidence interval (CI) (0.312, 0.875), P=0.014], foreign body type [OR=0.520, 95%CI (0.330, 0.820), P=0.005], incarceration site [OR=2.347, 95%CI (1.396, 3.947), P=0.001], incarceration time [OR=0.464, 95%CI (0.293, 0.736), P=0.001] were the influencing factors of complications. Conclusions The majority of foreign bodies in the upper digestive tract are animal bones. The incidence of complications increase in patients with age ≥ 60 years, sharp foreign body edges, incarceration in the upper segment of the esophagus, and long incarceration time. It is recommended to remove the sharp foreign bodies incarcerated in the upper segment of the esophagus from the elderly as soon as possible.
Objective To investigate the application of transverse fascia in inguinal hernia repair. Methods In this study, 617 patients underwent inguinal hernia repair between January 1990 and December 2005 in our hospital were included, which were divided into two groups according to different operative ways: transverse fascia method group (n=337) and Bassini method group (n=280). Then intraoperative results, postoperative complications, and rehabilitated results of patients in two groups were compared. Results Compared with Bassini method group, the patients in transverse fascia method group did not show significant difference in operative time and blood loss during operation (Pgt;0.05). The differences of severe postoperative pain, testicular swelling, the time of the body’s restore for normal activities, and recurrence rate of patients between two groups were significant (Plt;0.05), while the difference of hematoma of scrotum and infection of incisional wound (Pgt;0.05). Conclusion The strengthening of posterior wall by transverse fascia and reconstruction of inner ring is a simple and effective method for inguinal hernia repair.
Objective To investigate the relationship of macular microstructure and visual prognosis of micro-invasive vitrectomy for diabetic vitreous hemorrhage. Methods Fifty-three patients (53 eyes) with diabetic vitreous hemorrhage who underwent microinvasive vitrectomy were enrolled in this retrospective study. The preoperative and postoperative best-corrected visual acuities (BCVA) were recorded. The central foveal thicknesses (CFT) were measured after surgery by spectral domainoptical coherence tomography (SD-OCT). The median follow-up time was (12.81plusmn;8.22) months, ranging from six to 36 months. According to the results of SD-OCT at last follow-up time, macular edema (ME), epiretinal membrane (ERM), interrupted inside and outside section (IS/OS) and interrupted external limiting membrane (ELM) were macular abnormalities were observed. The preoperative and postoperative BCVA of different macular abnormalities were comparatively analyzed. The correlation between BCVA and macular microstructure were analyzed. Results The CFT was ranged from 103.00 mu;m to 498.00 mu;m,with the mean of（251.12plusmn;90.23） mu;m. Macular abnormalities were observed in 37 eyes (69.8%), and normal macula in 16 eyes (30.2%). Among 37 eyes with macular abnormalities, there were 20 eyes (37.7%) with ME, 12 eyes (22.6%) with ERM, 33 eyes (62.3%) with interrupted IS/OS, and 20 eyes (37.7%) with interrupted ELM. The BCVA of ME eyes decreased significantly than that in nonME eyes （t=-2.09，P＜0.05). The difference of BCVA in ERM and nonERM eyes was not statistically significant (t=-1.10,P＞0.05). The BCVA of interrupted IS/OS eyes decreased significantly more than that in continuous IS/OS eyes （t=-4.33,P＜0.05). The BCVA of interrupted ELM eyes decreased significantly more than that in continuous ELM eyes (t=-2.58, P＜0.05). The postoperative BCVA correlated positively with integrity of the IS/OS junction, CFT, and whether ME or not (r=7.65, 8.21, 4.99; P＜0.05), but insignificantly associated with integrity of the ELM and whether ERM or not (r=0.01, 0.82; P＞0.05). Conclusion The final visual acuity of patients with diabetic vitreous hemorrhage after micro-invasive vitrectomy is related to the CFT，the status of IS/OS junction, whether ME or not, but not related to integrity of the ELM or whether ERM or not.

Methods The clinical data of one case of pediatric donation after cardiac death liver to adult recipient was analyzed retrospectively and the literatures were reviewed. Results A 6-year-old girl pronounced brain death due to drowning and on the basis of cardiopulmonary criteria donated the organ．The liver graft weight was 598 g and the warm ischemic time was 10 min. The liver donor was transplanted to a 64-year-old woman，the graft to recipient weight ratio was 1.09%，the graft volume/estimated standard liver volume was 61.8%．The classic orthotopic liver transplantation without bypass was underwent，the postoperative recovery was smooth after the liver transplantation．The CT scan showed that the liver graft volume was 1 003cm3 on day 14 after operation．The patient was discharged on 45 d after orthotopic liver transplantation and the liver function was normal when followed-up 3 months after the operation. Conclusions Pediatric donation after cardiac death liver graft can be successfully utilized to adult recipient．Recipient selection and surgical approach should be decided by conditions of both donor and graft．
ObjectiveTo investigate the effect of multidisciplinary team (MDT) on perioperative complications and clinical efficacy of patients who were receiver radical operation to treat lung cancer by video-assisted thoracoscopic surgery (VATS). MethodsEighty patients in the Thoracic Surgery Department of First Hospital of Lanzhou University from December 2017 to February 2019 who were diagnosed lung cancer were divided into two groups. Forty patients in the MDT group were treated with MDT discussion. The control group consisted of 40 patients who were treated without MDT discussion. The incidence of postoperative complications and clinical efficacy were compared between the two groups . ResultsThere was no statistical difference in incision infection, atelectasis, pleural effusion and pulmonary leakage between the two groups. However, the incidence of postoperative pulmonary infection (5% vs. 20%, P=0.043) and the overall postoperative complications (17.5% vs. 42.5%, P=0.015) in the MDT group was lower than that in the control group with a statistical difference. In the MDT group, the operative time (140.3±8.0 min vs. 148.8±6.8 min, P<0.001), intraoperative bleeding ( 207.8±19.4 mL vs. 222.0±28.3 mL, P=0.010), lymph node dissection number (25.1±6.2 vs. 20.1±7.0, P=0.001), postoperative drainage (273.0±33.5 mL vs. 24.0±52.5 mL, P<0.001), drainage duration (81.9±6.1 h vs. 85.3±8.1 h, P=0.039), pain on the first day after surgery (4.6±0.7 vs. 5.4±0.7), P<0.001), pain on the second day (2.5±0.7 vs. 3.0±0.8, P=0.002), pain on the third day (1.1±0.8 vs. 1.5±0.6, P=0.014), postoperative activity time (40.7±6.7 h vs. 35.3±7.1 h, P<0.001), postoperative recovery time (6.8±0.9 d vs. 7.4±0.7 d, P=0.003), patient satisfaction (8.1±1.4 vs. 7.2±2.0, P=0.020) were significantly better than those of the control group with statistical differences. But there was no statistical difference in the conversion to thoracotomy between the two group. ConclusionMDT discussion can reduce the surgical risk and postoperative complications, improve the clinical efficacy and accelerate the postoperative rehabilitation of patients, which has a good clinical significance.
ObjectiveTo observe the expression of inflammatory cytokines in diabetic rats received posterior sub-Tenon capsule injection of triamcinolone acetonide (TA) and pan-retinal photocoagulation. MethodsA total of 48 Brown Norway rats received intraperitoneal injection of streptozotocin to establish the diabetic model. Diabetic rats were randomly divided into experimental group (20 rats), control group (20 rats) and blank group (8 rats). 50 μl TA or saline was injected into the posterior sub-Tenon capsule immediately after the photocoagulation in the experimental group and the control group, respectively. The blank group received no treatment. The mRNA and protein expression level of retinal vascular endothelial growth factor (VEGF), interleukin-6 (IL-6) and tumor necrosis fator-α (TNF-α) were measured by quantitative polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA) at 1, 3, 7 days after laser photocoagulation. ResultsThe mRNA and protein expression of VEGF, IL-6, TNF-α of the experimental group and control group were significantly higher than the blank group, the difference was statistically significant (P < 0.05). The mRNA and protein expression of VEGF, IL-6 and TNF-α of the experimental group were significantly lower than that of the control group. On day 1 after laser photocoagulation, the mRNA expression of VEGF was not statistically significant in the experimental group and control group (P > 0.05), the mRNA and protein expression of VEGF, IL-6, TNF-α of the two groups were statistically significant in the remaining observing time (P < 0.05). ConclusionPosterior sub-Tenon capsule injection of TA can effectively reduce retinal photocoagulation induced VEGF, IL-6, TNF-α expression.
