Objective:To investigate the clinical value of open abdomen therapy in non-traumatic critically patients.Methods:The retrospective cohort study was conducted. The clinical data of 23 non-traumatic critically patients who underwent open abdomen therapy in 5 hospitals in China from July 2015 to July 2024 were collected. There were 17 males and 6 females, aged 70(range, 24-84)years. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Repeated measurement data were analyzed using the repeated ANOVA, and pairwise comparison within groups was conducted using the least significant difference method. The Boruta algorithm was applied for analyzing variables related to survival outcomes. Results:(1) Treatment of patients undergoing open abdomen therapy. ① The intra-abdominal pressure, lactate, heart rate, central venous pressure, mean arterial pressure, sequential organ failure assessment score of 23 patients from preoperation to postoperative day 3 were changed from (19.7±5.4)mmHg (1 mmHg=0.133 kPa), (6.1±1.9)mmol/L, (120±14)beats/minutes, (13.1±4.3)cmH 2O (1 cmH 2O=0.098 kPa), (58.8±6.8)mmHg, 13.2±1.8 to (10.6±1.3)mmHg, (2.3±0.6)mmol/L, (95±10)beats/minutes, (8.8±2.0)cmH 2O, (75.2±8.5)mmHg, 10.1±1.6, respectively, showing significant differences in the time effect of changes in the above indicators ( Ftime=46.40, 29.19, 24.91, 11.84, 27.81, 11.71, P<0.05). ② The oxygenation index, total intake, total output of 23 patients from preoperation to postoperative day 3 were changed from (255.0±54.2)mmHg, (5388±1562)mL, (2 520±630)mL to (291.7±25.0)mmHg, (2 886±866)mL, (3 221±923)mL, respectively, showing significant differences in the time effect of changes in the above indicators ( Ftime=7.61, 13.83, 2.97, P<0.05). ③The daily caloric intake, daily protein supplementation of 23 patients from preoperation to postoperative day 3 were changed from (465±116)kcal, (18±5)g to (1 628±472)kcal, (60±18)g, respectively, showing significant differences in the time effect of changes in the above indicators ( Ftime=40.31, 41.23, P<0.05). (2) Patients outcomes after open abdomen therapy. Of 23 patients, 18 cases survived and 5 cases died. The duration of intensive care unit stay and duration of hospital stay of 23 patients were 26(range, 5-82)days and 40(range, 5-98)days. Twelve of 23 patients received renal replacement therapy for 12 (range, 5-32)days. Time of pain and sedation management, mechanical ventilation, antimicrobial therapy, vasopressor therapy of 23 patients were 13(range, 5-74)days, 12(range, 5-74)days,20(range, 5-50)days, 6(range, 2-35)days. (3) Analysis of variables related to survival outcomes for patients after open abdomen therapy. Results of Boruta analysis showed that postoperative high-output enteric fistula, postoperative bile fistula, postoperative intra-abdominal hemorrhage, postoperative enteric air fistula, and preoperative mean arterial pressure were significantly associated with survival outcomes. Conclusions:Open abdomen therapy is effective in the treatment of non-traumatic critically patients. Postoperative high-output enteric fistula, postoperative bile fistula, postoperative intra-abdominal hemorrhage, postoperative enteric air fistula, and preoperative mean arterial pressure reduction are significantly associated with survival outcomes.

Objective:To investigate the roles of T helper 17(Th17)cells and regulatory T(Treg)cells, interleukin(IL)-17 levels, and IL-6 levels in the pathogenesis of Henoch-Schonlein purpura(HSP)complicated with Helicobacter pylori(HP)infection in children. Methods:Children diagnosed with acute HSP and/or HP infection by the Department of Pediatrics, Xiamen Maternal and Child Health Care Hospital from January 2017 to December 2018 were enrolled in the study.There were 15 children with HSP complicated with HP infection(HSP-HP group), 26 children with HSP(HSP group), and 21 children with HP infection(HP group). Twenty healthy children of the same age over the same period were included in the healthy control group.The proportions of Th17 cells and Treg cells were tes-ted by flow cytometry(FCM), and concentrations of IL-17 and IL-6 in plasma were measured by enzyme linked immunosorbent assay(ELISA).Results:(1)Compared with that of the healthy control group [(1.42±0.63)%], the proportion of Th17 cells in the HSP-HP group, HSP group and HP group [(2.79±0.78)%, (2.04±0.77)%, (2.08±0.86)%] was significantly increased( F=5.271, P<0.05). The levels of IL-17 and IL-6 in the HSP-HP group [(552.16±121.13) ng/L and (12.36±6.55) ng/L], HSP group [(506.39±113.62) ng/L and(11.82±5.01) ng/L] and HP group [(483.14±121.77) ng/L and (10.19±3.87) ng/L] were significantly higher than those in the healthy control group [(302.96±82.83) ng/L and (7.81±2.04) ng/L]( F=13.113, 6.692, all P<0.01). The proportion of Treg cells in the HSP-HP group [(1.35±0.49)%], HSP group [(1.13±0.86)%] and HP group [(1.09±0.65)%] was significantly lower than that in the healthy control group [(2.31±0.83)%]( F=6.983, P<0.05). (2)The proportion of Th17 cells and the level of IL-17 in the HSP-HP group were significantly higher than those in the HSP and HP groups(all P<0.05). There was no significant difference in the proportion of Th17 cells and the level of IL-17 between the HSP group and HP group(all P>0.05). There was no significant difference in the proportion of Treg cells and the level of IL-6 among the HSP-HP group, HSP group, and HP group(all P>0.05). Conclusions:The imbalance of Th17/Treg cells in peripheral blood may contribute to the development of HSP-HP, HSP and HP infection in children.High expression of Th17 cells and their related IL-17 is more prominent in children with HSP-HP.

Objective:To study the pupillary centroid shift of myopia and characteristics of pupil diameter change from scotopic to photopic condition.Methods:A case series study was carried out, 140 eyes of 70 myopia patients from September to November 2016 in Tianjin Eye Hospital were enrolled.The pupillary centroid shift and pupil diameter parameters were measured by visual quality analyzer from scotopic (0.017 lx) to photopic (10.400 lx) condition.This study followed the Declaration of Helsinki.Results:Under the scotopic and photopic conditions, the pupil diameter was positively correlated between the bilateral eyes (scotopic: rs=0.85, P<0.001; photopic: r=0.85, P<0.001), and the pupil diameter variation from scotopic to photopic condition was positively correlated between the bilateral eyes ( r=0.75, P<0.001). The pupil diameter in scotopic and photopic conditions, and the change of pupil diameter in the right eyes were significantly higher than those in the left eyes (all at P<0.05). The pupillary centroid shift was within 0.2 mm in the left eyes of 94.2% (66/70) subjects and in the right eyes of 97.1%(68/70) subjects.The pupillary centroid shift of all subjects was within 0.3 mm.From scotopic to photopic condition, the pupil centroid was mainly shift to the nasal superior direction.There was no significant correlation between pupil diameter and age or gender.There was no significant correlation between pupillary centroid shift and age, diopter or pupil diameter. Conclusions:The binocular pupillary centroid shift are symmetrical from scotopic to photopic condition in myopic eyes, and the pupil centroid mainly shift to nasal superior direction.

Lung cancer is the most common cancer and the leading cause of cancer death. Non-small cell lung cancer (NSCLC) represents over 85% of all lung cancers, and up to 50% of Asian NSCLC patients harboring epidermal growth factor receptor (EGFR) gene mutations. A number of studies have consistently demonstrated that uncommon EGFR-mutated NSCLC patients treated with EGFR-tyrosine kinase inhibitors (EGFR-TKIs) can achieve better survival outcomes. However, because uncommon EGFR mutations are generally associated with reduced sensitivity to EGFR-TKIs, which will bring a negative impact on the result of the study, the majority of clinical trials investigating the efficacy of EGFR-TKIs have included only patients with common EGFR mutations. In addition, uncommon EGFR mutations are rare in themselves, leading to the small number of such patients enrolled in these trials. Due to the small number and highly heterogeneous sensitivity of uncommon EGFR mutations, the efficacy of EGFR-TKIs in patients harboring uncommon EGFR mutations remains elusive. This article reviews the efficacy of EGFR-TKIs in patients with uncommon EGFR mutations, and give some reasonable advice about the selection of treatments for patients with NSCLC who harbor uncommon EGFR mutations.
