Objective:To observe the clinical effect of Shenfu injection in preventing septic cardiomyopathy (SIC) in septic patients.Methods:From June 2022 to January 2023, patients with sepsis or septic shock who did not develop SIC were randomly divided into treatment group and control group according to the ratio of 1:1. In the treatment group, Shenfu injection (50 mL) was pumped intravenously once every 12 hours for 5 days. In the control group, 50 mL of normal saline was pumped intravenously once every 12 hours, and the course of treatment was 5 days. The primary end point was the incidence of SIC in the first 5 days. The secondary end points were the application time of vasoactive drugs, fluid balance in the previous week, hospitalization time in ICU, total ventilation time and 28-day mortality.Results:112 patients were randomly divided into two groups. Seven patients in the treatment group were excluded twice, and finally 49 patients were included in the analysis, while six patients in the control group were excluded twice and 50 patients included in the analysis. The total incidence of SIC in the treatment group within 5 days was significantly lower than that in the control group (42.9% vs. 64.0%, P = 0.035). Among them, the left ventricular systolic dysfunction in the treatment group was significantly lower than that in the control group (24.5% vs 52.0%, P=0.005), and there was no significant difference in the incidence of left ventricular diastolic dysfunction between the two groups. The incidence of right ventricular dysfunction in the control group was 28.0%, which was significantly higher than 10.2% in the treatment group ( P = 0.025). The duration of using vasoconstrictors in the treatment group was 75(48, 97) hours, which was significantly lower than 97(66, 28) hours in the control group ( P = 0.039). The duration of inotropic drugs use in the treatment group was 32(18, 49) h, which was also significantly shorter than 44(25, 61) h in the control group ( P=0.046). The fluid balance of the control group in the first week was (1 260±850) mL, which was significantly higher than (450±520) mL in the treatment group ( P=0.008). There was no statistical difference in ICU stay, total ventilation time and 28-day mortality between the two groups (all P > 0.05). Conclusion:Early application of Shenfu injection can significantly reduce the incidence of SIC, accompanied by less use of vasoactive drugs and positive fluid balance, which has a good clinical application prospect.

AIM: To compare the clinical effectiveness of using multifocal defocus spectacle lenses, orthokeratology lenses, and single-vision spectacle lenses in patients with myopia and small-angle intermittent exotropia.METHODS: This retrospective study included 150 patients aged 8-15 years with basic intermittent exotropia, strabismus of -10△ to -20△ prism diopters(D)(block lenses), and spherical equivalents of -1.00 to -5.50 D, who visited our hospital from June 2021 to September 2022. They were selected and divided into three groups on a voluntary basis: the HAL group(50 patients with multifocal myopia defocus spectacle lenses), the OK lens group(50 patients with nighttime orthokeratology lenses), and the SVL group(50 patients with regular single-vision spectacle lenses). After wearing the lenses consistently, changes in axial length, prism diopters with the naked eye and lenses(prism at 33 cm), positive fusional vergence of blurred points, and near stereopsis were observed and compared among groups before intervention and after 1 a. The Newcastle control score(NCS)was used to evaluate the eye position control ability of the patients in the three groups.RESULTS: Before the intervention, the axial lengths of the HAL, OK lens, and SVL groups were 24.83±0.91, 24.93±0.97, and 24.98±0.68 mm, respectively(P>0.05). After 1 a, the axial lengths of the three groups were 25.02±0.90, 25.18±0.97, and 25.45±0.65, respectively(P<0.05). Compared with an increase of 0.47±0.30 mm in the SVL group after 1 a, the axial length of the HAL and OK lens groups increased by 0.19±0.06 and 0.25±0.21 mm, respectively(both P<0.05). Before intervention, the prism diopters of the HAL, OK lens, and SVL groups measured using the prism were -15.00△±3.12△, -14.34△±3.00△ and -14.06△±3.22△, respectively. After 1 a, the prism diopters of the three groups with lenses were -9.34△±3.84△, -18.42△±4.41△, and -19.58△±5.21△, respectively, which increased by 5.66△±2.13△, -4.08△±3.34△, and -5.52△±3.70△, respectively, compared with the preintervention values(P<0.05). Before intervention, the near stereopsis in the HAL, OK lens, and SVL groups were 89.20″±54.65″, 93.00″±52.54″, and 88.40″±55.31″, respectively(P>0.05). After 1 year, near stereopsis in the groups were 76.00″±20.40″, 81.20″±18.91″, and 100.60″±51.41″, respectively(P<0.05). The positive fusional vergence(fuzzy point)of the three groups was 15.04±1.97, 15.14±1.67, and 14.62±1.47, respectively, before intervention(P>0.05), and it was 17.10±2.02, 13.12±1.41, and 13.26±2.45, respectively, after 1 a(P<0.05). In addition, the eye position control in the HAL group was significantly better than that in the OK lens and SVL groups after wearing lenses for 1 a(P<0.05).CONCLUSION: For patients with myopia and small-angle intermittent exotropia, wearing HAL can effectively control changes in strabismus and axial length compared with OK lenses and SVL, particularly for better control of strabismus, whereas wearing OK lenses or SVL would result in exotropic drifts. Stereopsis and positive fusional vergence were significantly improved in the HAL group.

Objective:To compare the efficacy of high-flow nasal cannula oxygen therapy (HFNC) and non-invasive ventilation (NIV) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with moderate typeⅡ respiratory failure, to clarify the feasibility of HFNC in the treatment of AECOPD, and to explore the influencing factors of HFNC failure.Methods:This study was a randomized controlled trial of non-inferiority. Patients with AECOPD with moderate type Ⅱ respiratory failure [arterial blood gas pH 7.25-7.35, partial pressure of arterial blood carbon dioxide (PaCO 2)> 50 mmHg] admitted to the Intensive Care Unit (ICU) from January 2018 to December 2021 were randomly assigned to the HFNC group and NIV group to receive respiratory support. The primary endpoint was the treatment failure rate. The secondary endpoints were blood gas analysis and vital signs at 1 h, 12 h, and 48 h, total duration of respiratory support, 28-day mortality, comfort score, ICU length of stay, and total length of stay. Multivariate logistic regression analysis was used to evaluate the failure factors of HFNC treatment. Results:Totally 228 patients were randomly divided into two groups, 108 patients in the HFNC group and 110 patients in the NIV group. The treatment failure rate was 29.6% in the HFNC group and 25.5% in the NIV group. The risk difference of failure rate between the two groups was 4.18% (95% CI: -8.27%~16.48%, P=0.490), which was lower than the non-inferiority value of 9%. The most common causes of failure in the HFNC group were carbon dioxide retention and aggravation of respiratory distress, and the most common causes of failure in the NIV group were treatment intolerance and aggravation of respiratory distress. Treatment intolerance in the HFNC group was significantly lower than that in the NIV group (-29.02%, 95% CI -49.52%~-7.49%; P=0.004). After 1 h of treatment, the pH in both groups increased significantly, PaCO 2 decreased significantly and the oxygenation index increased significantly compared with baseline (all P < 0.05). PaCO 2 in both groups decreased gradually at 1 h, 12 h and 48 h after treatment, and the pH gradually increased. The average number of daily airway care interventions and the incidence of nasal and facial lesions in the HFNC group were significantly lower than those in the NIV group ( P < 0.05), while the comfort score in the HFNC group was significantly higher than that in the NIV group ( P=0.021). There was no significant difference between the two groups in the total duration of respiratory support, dyspnea score, ICU length of stay, total length of stay and 28-day mortality (all P > 0.05). Multivariate logistic regression analysis showed that acute physiology and chronic health evaluation Ⅱ score (≥15), family NIV, history of cerebrovascular accident, PaCO 2 (≥60 mmHg) and respiratory rate (≥32 times/min) at 1 h were independent predictors of HFNC failure. Conclusions:HFNC is not inferior to NIV in the treatment of AECOPD complicated with moderate type Ⅱ respiratory failure. HFNC is an ideal choice of respiratory support for patients with NIV intolerance, but clinical application should pay attention to the influencing factors of its treatment failure.

Objective:To observe the application effect of a self-designed assisted abdominal breathing rehabilitation device in elderly patients undergoing postoperative chemotherapy for lung cancer.Methods:Self-designed an assisted abdominal breathing rehabilitation device. Used the convenience sampling method, 116 elderly patients admitted to the First Affiliated Hospital of Anhui Medical University from April 2021 to April 2022 undergoing postoperative chemotherapy for lung cancer were selected as study subjects, and they were divided into control and observation groups by the random number table method, with 58 cases in each group. The control group received routine abdominal breathing training, and the observation group used auxiliary abdominal breathing rehabilitation device for abdominal breathing training, and compared the training compliance rate, lung function indexes and six minutes-walk test scores of the two groups before and after 2 weeks of training.Results:After 2 weeks of training, the training compliance rate of patients in the observation group was 100.00% (58/58), which was higher than 87.93% (51/58) in the control group, and the difference was statistically significant ( χ 2=7.45, P<0.05). After 2 weeks of training, FEV 1, FVC, FEV 1/FVC were (1.81 ± 0.29) L, (1.98 ± 0.32) L, (91.91 ± 5.98) % respectively in the observation group, and (1.49 ± 0.31) L, (1.73 ± 0.41) L, (87.11 ± 9.44) % respectively in the control group, there were statistically significant differences between the two groups ( t=-4.13, -2.60, -2.36, all P<0.05). After 2 weeks of training, the six minutes-walk test score was (0.86 ± 0.71) points in the observation group and (1.02 ± 0.74) points in the control group, and the difference was statistically significant ( t=2.05, P<0.05). Conclusions:An assisted abdominal breathing rehabilitation device helps to improve the training compliance rate, enhance lung function recovery and improve exercise endurance in elderly patients undergoing chemotherapy after lung cancer surgery.

Objective:To analyze the efficacy of nutrition intervention combined with rehabilitation exercise in elderly patients with chronic heart failure (CHF) complicated by sarcopenia.Methods:In this randomized controlled trial, seventy CHF patients with sarcopenia, aged 80 years or older, who had received standard CHF medication treatment and had stable conditions with preserved ejection fraction (HFpEF) from June 2021 to October 2022 at the China-Japan Friendship Hospital outpatient clinic were continuously selected. The patients were randomly divided into a test group ( n=35) and a control group ( n=35) using a random number table. The test group continued the original heart failure medication treatment, and on the basis of daily meal, supplemented with whey protein powder [37 g per serving (including 16.2 g of whey protein, 145 kcal), twice a day]; they were given resistance exercise primarily focused on resistance training (5 sets of exercises, progressively increasing to 3 days per week, twice a day, 5 sets per session, 20 repetitions per set). The control group maintained the original heart failure medication treatment plan and lifestyle. The body mass index, appendicular skeletal muscle mass index (ASMI), grip strength, Five-Times-Sit-to-Stand Test, 6-meter walking speed, 6-minute walk test, brain natriuretic peptide (BNP), left ventricular ejection fraction, ratio of early mitral flow peak velocity to early mitral annulus diastolic peak velocity (E/e′), serum albumin, hemoglobin, and serum creatinine were compared between the two groups before and after 3 months of intervention using t-tests and chi-square tests to analyze the efficacy of nutrition intervention combined with rehabilitation exercise in elderly patients with CHF complicated by sarcopenia. Results:Among the 70 patients, there were 42 males and 28 females. There was no significant difference in baseline data between the test group and the control group (all P>0.05). After 3 months of intervention, ASMI, grip strength and 6 min walking distance in the test group were all significantly higher than those in the control group [(6.43±1.07) vs (6.09±0.86) kg/m 2, (27.75±2.13) vs (23.45±0.47) kg, (361.51±58.71) vs (273.50±69.85) m], and significantly higher than those before intervention [(5.99±1.45) kg/m 2, (23.55±9.64) kg, (273.50±69.86) m]. The time of Five-Times-Sit-to-Stand Test, BNP and E/e′ in the test group were both significantly lower than those in the control group [(11.20±2.09) vs (15.36±0.46) s, (278.80±58.69) vs (400.80±87.86) ng/L, (11.10±0.81) vs (14.66±1.90)], and significantly lower than those before intervention [(18.51±2.90) s, (407.50±122.74) ng/L and (14.00±1.15)]. There was no significant difference in remaining indicators between the two groups (all P>0.05). Conclusion:Nutritional intervention combined with rehabilitation exercise primarily focused on whey protein supplementation and resistance training can significantly improve limb muscle mass, muscle strength, muscle function, and cardiac function in elderly patients with CHF complicated by sarcopenia on the basis of heart failure medication treatment.

Objective:To investigate the effect of different P2Y12 inhibitors on the long-term prognosis of patients with diabetes mellitus (DM) and acute coronary syndrome (ACS), with or without the CYP2C19 loss-of-function (LOF) gene. Method:266 consecutive ACS patients undergoing percutaneous coronary intervention (PCI) were enrolled. According to the CYP2C19 LOF genotype, the patients were divided into rapid metabolizing-type (without the CYP2C19 LOF gene) and moderate-slow metabolizing type (with the CYP2C19 LOF gene). Each type was divided into the A group (with diabetes) and the B group (without diabetes). Each group was divided into the ticagrelor subgroup and the clopidogrel subgroup according to the type of P2Y12 platelet inhibitor. The MACE events were recorded for each subgroup over 3 years, and the prognostic impact of the CYP2C19 LOF genotype and the type of P2Y12 used were analyzed. Results:There were no significant differences in MACE, revascularization, stroke, heart failure rehospitalization, major bleeding, or all-cause mortality among subgroups of patients with rapid metabolizing type at 3 years after PCI (all P>0.05). In patients with moderate-slow metabolizing-type, the use of tegretol significantly reduced the probability of MACE events and cardiac revascularization (all P<0.01) and significantly reduced the reoccurrence of heart attack in patients with DM. Conclusions:In DM combined with ACS patients with rapid metabolizing type, the choice of different P2Y12 inhibitors after PCI had no significant effect on their prognosis. In DM combined with ACS patients with moderate-slow metabolizing type, tegretol not only significantly reduced the incidence of MACE, revascularization, and reinfarction, but also did not increase the risk of major bleeding. In terms of reducing the reoccurrence of heart attack, the benefit of using tegretol in the DM patients was greater than in the non-DM patients.

Objective:To investigate the association of postprandial hypotension(PPH)with insulin and neurotensin(NT)in very old adults.Methods:In this retrospective study, 22 people with PPH and 21 without non-PPH, aged ≥80, were enrolled from patients hospitalized at the First Division of the Health Department of China-Japan Friendship Hospital between September 2015 and October 2021.The levels of blood pressure, blood glucose, insulin and NT at fasting and 30, 60, 90 and 120 minutes after a meal were monitored.Changes in values of each parameter before and after a meal were compared between the two groups, and the correlation of the maximum decrease in postprandial blood pressure with the maximum increase in blood glucose, insulin and neurotensin was analyzed.Results:The maximum decrease in postprandial systolic blood pressure(SBP)in the PPH group was significantly higher than that in the non-PPH group[(35.5±13.2)mmHg(1 mmHg=0.133 kPa) vs.(16.0±8.6)mmHg, t=4.135, P<0.01)]. The maximum increase in postprandial insulin was significantly higher than that in the non-PPH group[(20.9±4.2)mU/L vs.(12.1±4.1)mU/L, t=3.949, P<0.01)]. There was no statistically significant difference between the PPH and non-PPH groups in the maximum increase in postprandial blood glucose[(3.6±1.8)mmol/L vs.(2.5±0.5)mmol/L, t=1.912, P>0.05)]or NT[65.7(22.0, 110.1)ng/L vs.112.2(47.2, 270.2)ng/L, Z=1.817, P>0.05)]. There was a significant positive correlation between the maximum decrease in postprandial systolic blood pressure and the maximum increase in insulin( r=0.907, P<0.05). There was no correlation between the maximum decrease in postprandial systolic blood pressure and the maximum increase in blood glucose( r=0.016, P>0.05). There was no correlation between the maximum decrease in postprandial systolic blood pressure and the maximum increase in NT( r=0.396, P>0.05). Conclusions:The PPH is related to abnormal increases in postprandial insulin secretion.

Objective:To explore the application effect of family-centered empowerment model (FCEM) in rehabilitation nursing of children with femoral shaft fractures treated by skin traction.Methods:A retrospective case-control study was conducted to analyze the clinical data of 107 children with femoral shaft fractures treated with skin traction in Anhui Children′s Hospital from April 2019 to October 2021, including 67 males and 40 females; aged 1.5-5.0 years [2.8(2.0, 3.5)years]. Fracture types included oblique fracture ( n=50), comminuted fracture ( n=26), transverse fracture ( n=14) and spiral fracture ( n=17). FCEM nursing was implemented in 55 patients (family empowerment group) and routine home rehabilitation nursing guidance was performed in 52 patients (routine nursing group). The face, legs, activity, cry, consolability (FLACC) behavioral score on admission and at days 1, 3 and 7 after skin traction, treatment compliance rate at 1 month after skin traction, complication rate at 1 month after skin traction, length of hospital stay and fracture healing time were compared between the two groups. Results:All patients were followed up for 12-18 weeks [13.4(12.7, 13.9)weeks]. There was no significant difference in FLACC behavioral score between the two groups on admission ( P>0.05). The FLACC behavioral score was (4.0±0.7)points,(3.4±0.6)points and (2.4±0.6)points in family empowerment group at days 1, 3 and 7 after skin traction, lower than (4.8±0.7)points, (3.9±0.8)points and (3.3±0.5)points in routine nursing groups (all Ρ<0.01). One month after skin traction, treatment compliance was excellent in 51 patients, good in 4, poor in 0, with treatment compliance rate of 92.7% (51/55) in family empowerment group, and was excellent in 40 patients, good in 9, poor in 3, with treatment compliance rate of 76.9% (40/52) in routine nursing group ( Ρ<0.05). The complication rate was 5.4% (3/55) in family empowerment group, lower than 21.2% (11/52) in routine nursing group ( Ρ<0.05). The length of hospital stay and fracture healing time were (15.6±0.3)days and (7.1±0.8)weeks in family empowerment group, shorter than (16.8±0.3)days and (8.2±0.4)weeks in routine nursing group (all Ρ<0.01). Conclusion:For children with femoral shaft fractures treated by skin traction, nursing using FCEM can alleviate pain, improve treatment compliance, reduce complication rate, reduce hospital stay and shorten fracture healing time.

Objective:To investigate the function of gasdermin D (GSDMD) in intestinal damage of mice with severe acute pancreatitis (SAP).Methods:The healthy C57BL/6 mice were divided into four groups randomly, including normal saline (NS) group, small interfering RNA (siRNA)-NS group, SAP model group and siRNA-SAP group, with 6 mice in each group. The SAP mouse model was reproduced by intraperitoneal injection of caerulein 50 μg/kg combined with lipopolysaccharide (LPS) 10 mg/kg; the NS group was given the same amount of NS; in the siRNA-SAP group and siRNA-NS group, siRNA 50 mg/kg was injected through the tail vein three times before modeling or injection of NS. The blood of mice eyeball in each group was taken 12 hours after modeling, and serum interleukins (IL-1β, IL-18) levels were detected by enzyme linked immunosorbent assay (ELISA). The mice were sacrificed to observe the general changes in abdominal cavity, the pancreas and ileum tissues were taken to observe the pathological changes under a light microscope. The expression of long-chain non-coding RNA uc.173 (lnc uc.173) was detected by reverse transcription-polymerase chain reaction (RT-PCR). Immunohistochemical method was used to detect the expression of tight junction proteins zonula occluden-1 (ZO-1) and Occludin in intestinal mucosal epithelial cells. Western blotting was used to detect the GSDMD protein expression level in the intestinal tissue.Results:The serum levels of IL-1β and IL-18 in the SAP model group were significantly higher than those in the NS group and the siRNA-NS group [IL-1β (ng/L): 146.66±1.40 vs. 44.48±5.76, 81.49±10.75, IL-18 (ng/L): 950.47±177.09 vs. 115.43±16.40, 84.84±21.90, all P < 0.05]; and the levels of IL-1β and IL-18 in the siRNA-SAP group were significantly lower than those in the SAP model group [IL-1β (ng/L): 116.26±15.54 vs. 146.66±1.40, IL-18 (ng/L): 689.96±126.08 vs. 950.47±177.09, both P < 0.05]. General observation showed that there were no obvious abnormalities in the abdominal cavity of the mice in the NS and siRNA-NS groups; the mice in the SAP model group and the siRNA-SAP group had different degrees of edema and congestion in the intestine; compared with the SAP model group, the abnormalities in the siRNA-SAP group was significantly reduced. Under light microscope, there were no obvious changes in the pancreas and intestinal mucosa in the NS group and the siRNA-NS group; the pancreatic tissue of the SAP model group and the siRNA-SAP group had different degrees of edema, inflammatory cell infiltration, and lobular structure damage, and the intestinal mucosa was damaged to a certain degree, and the villi were broken to varying degrees, but the damage in the siRNA-SAP group was lighter. The results of RT-PCR showed that the expression of lnc uc.173 in the intestinal tissues of the model SAP group was significantly lower than that of the NS group and the siRNA-NS group (2 -ΔΔCt: 0.26±0.12 vs. 1.01±0.37, 0.67±0.32, both P < 0.05), while the expression of lnc uc.173 in the siRNA-SAP group was significantly higher than that in the SAP model group (2 -ΔΔCt: 0.60±0.39 vs. 0.26±0.12, P < 0.05). Immunohistochemistry showed that ZO-1 and Occludin proteins in the NS group were distributed along the epithelial cells of the intestinal mucosa, showing a strong expression; ZO-1 and Occludin expressions were significantly reduced in the SAP model group and siRNA-SAP group, but the expressions in the siRNA-SAP group was higher than that in the SAP model group. Western blotting showed that the expression level of GSDMD protein in the intestinal tissues of the SAP model group was significantly higher than that of the NS group and the siRNA-NS group [GSDMD protein (GSDMD-N/β-actin): 1.99±0.46 vs. 1, 1.00±0.78, both P < 0.05]. Compared with the SAP model group, the expression of GSDMD protein in the siRNA-SAP group was significantly decreased [GSDMD protein (GSDMD-N/β-actin): 1.42±0.42 vs. 1.99±0.46, P < 0.05]. Conclusions:The systemic inflammatory response and intestinal mucosal barrier damage of SAP mice may be related to the increase of GSDMD expression in intestinal tissues. GSDMD mediates cell pyrolysis to promote the release of inflammatory factors, cause intestinal injury, and down-regulate the expression of intestinal epithelial cell tight junction proteins such as ZO-1 and Occludin, resulting in intestinal mucosal damage.

Objective:To explore the relationship between the selection of different P2Y 12 inhibitors and the long-term prognosis of acute coronary syndrome (ACS) patients with and without CYP2C19 defect gene. Method:289 consecutive ACS patients who underwent percutaneous coronary intervention (PCI) at Tianjin Third Central Hospital from March 2016 to October 2016 were selected for CYP2C19 gene polymorphism detection. According to the detection results, the patients were divided into group A (with CYP2C19 loss-of-function gene, 199 cases) and group B (without CYP2C19 loss-of-function gene, 90 cases). After PCI, different P2Y 12 inhibitors were selected. The patients were followed up for 3 years, and 23 cases were lost to follow-up. Finally, 182 cases were enrolled in group A and 84 cases were enrolled in group B. According to whether there were major adverse cardiovascular events (MACE) within 3 years, the patients in groups A and B were divided into MACE subgroups (58 cases, 32 cases) and non-MACE subgroups (124 cases, 52 cases). The single factor analysis of the two subgroups in groups A and B was carried out based on the patient's clinical data, coronary artery disease and intervention status, and postoperative drug treatment plan. Risk factors with statistical significance ( P<0.05) were selected, and multivariate logistic regression analysis was performed on groups A and B to compare the effects of different P2Y 12 inhibitors on the prognosis of the two groups. Results:The differences in platelet volume, fasting blood glucose, HbA1c, left ventricular end-diastolic diameter, proportion of single-branch lesions, proportion of intervention for left main lesions, and dual antiplatelet therapy were statistically significant between the two subgroups in group A (all P<0.05). The differences in low-density lipoprotein (LDL), left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter, proportion of two-branch lesions, proportion of three-branch lesions, and proportion of using tirofeben were statistically significant between the two subgroups in group B (all P<0.05). In the group A, the choice of different P2Y 12 inhibitors was the independent risk factor for the long-term prognosis. Compared with patients treated with Ticagrelor, the probability of long-term MACE was 11.971 times larger ( OR=12.971, 95% CI: 5.028~33.464, P<0.001) among patients treated with Clopidogrel 75 mg/day, and 5.029 times larger ( OR=6.029, 95%CI: 2.278~15.958) among patients treated with Clopidogrel 100 mg/day. No significant correlation was witnessed between different P2Y 12 inhibitors and long-term prognosis in group B. In the group B, different P2Y 12 inhibitors have no significant correlation with their long-term prognosis of patients( P>0.05). Conclusions:For ACS patients with CYP2C19 loss-of-function gene, the choice of P2Y 12 inhibitors is associated with their long-term MACE events after PCI. Ticagrelor therapy brings the lowest risk of long-term MACE. For those without CYP2C19 loss-of-function gene, the correlation between the choice of different P2Y 12 inhibitors and their prognosis is not significant.

Objective:To investigate the effects of poly (ADP-ribose) polymerase-1(PARP-1) in intestinal mucosal barrier injury in rat model with severe acute pancreatitis (SAP).Methods:Twenty healthy male Wistar rats were divided into four groups ( n=5 each group) using a random table method: control, SAP, 3-aminobenzamide (3-AB), and 3-AB control groups. The SAP model was induced by intraperitoneal injection of cerulean with lipopolysaccharide. At 30 min, the rats were treated with the PARP-1 inhibitor, 3-AB, or normal saline,separately. After 12 h, all rats were sacrificed to harvest pancreas tissues, intestines tissues, and blood from the hearts for index detection. Serum amylase (AMY) and interleukin (IL)-6 levels were measured using an automatic biochemical instrument and enzyme-linked immunosorbent assay (ELISA), respectively.The protein expression of PARP-1 and nuclear factor (NF-κB) were measured using Western blot and that of occludin was measured using an immunohistochemical test. One-way analysis of variance was used for comparison of multiple groups of variables. Non-parametric tests of rank conversion were used when variances were not uniform. A P <0.05 was considered statistically significant. Results:Compared to the control group, the following indexes in the SAP group were significantly increased: ascites (with serious hemorrhage and necrosis in the pancreas and disordered intestinal villi),serum AMY and IL-6 levels, and the expression of PARP-1 and NF-κB. However, Occludin expression was significantly decreased. There was no significant difference between 3-AB group and 3-AB control group. Compared to the SAP group, the severity of SAP and pancreatitis-associated intestinal injury was significantly attenuated with the administration of 3-AB. Serum AMY and IL-6 levels were significantly decreased (serum AMY: 1 879.25 ± 736.6 U/L vs 5 569.33 ± 1993.48 U/L; IL-6: 77.98 ± 20.65 pg/mL vs 209.14 ± 79.08 pg/mL, both P<0.05), but the expression of PARP-1 and NF-κB were significantly increased (PARP-1: 1.44 ± 0.09 vs 1.49 ± 0.13; NF-κB: 0.63 ± 0.09 vs 0.96±0.08, both P<0.05). Similarly, Occludin expression was significantly decreased (6.7±1.5 vs 3.2±1.1, P<0.05). Conclusions:Inhibition of PARP-1 has protective effects on SAP associated intestinal mucosal barrier damage. The mechanism may be related to the inhibition of NF-κB signaling pathway and increase intestinal mucosal Occludin protein expression.

Objective:To compare the therapeutic effects of nasal high-flow oxygen therapy (HFNC) and nasal canal oxygenation (NCO) during breaks off non-invasive ventilation (NIV) for acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and to explore the feasibility of NIV combined with HFNC in the treatment of AECOPD.Methods:From August 2017 to July 2019, AECOPD patients with type Ⅱrespiratory failure (arterial blood gas pH <7.35, PaCO 2 > 50 mmHg) who were treated with NIV were randomly (random number) assigned to the HFNC group and NCO group at 1:1. The HFNC group received HFNC treatment during breaks from NIV and the NCO group received low-flow NCO during the NIV interval. The primary endpoint was the total respiratory support time. The secondary endpoints were endotracheal intubation, duration of NIV treatment and breaks from NIV, length of ICU stay, total length of hospital stay and so on. Results:Eighty-two patients were randomly assigned to the HFNC group and the NCO group. After secondary exclusion, 36 patients in the HFNC group and 37 patients in the NCO group were included in the analysis. The total respiratory support time in the HFNC group was significantly shorter than that in the NCO group [(74 ± 18) h vs. (93 ± 20) h, P = 0.042]. The total duration of NIV treatment in the HFNC group was significantly shorter than that in the NCO group [(36 ± 11) h vs. (51 ± 13) h, P=0.014]. There was no significant difference of the mean duration of single break from NIV between the two groups, but durations of break from NIV in the HFNC group were significantly longer than those in the NCO group since the third break from NIV ( P < 0.05). The intubation rates of the HFNC and NCO groups were 13.9% and 18.9%, respectively, with no significant difference ( P=0.562). The length of ICU stay in the HFNC group was (4.3 ± 1.7) days, which was shorter than that in the NCO group [(5.8 ± 2.1) days, P=0.045], but there was no significant difference in the total length of hospital stay between the two groups. Heart rate, respiratory rate, percutaneous carbon dioxide partial pressure and dyspnea score during the breaks from NIV in the NCO group were significantly higher than those in the HFNC group, and the comfort score was lower than that in the HFNC group ( P<0.05). Conclusion:For AECOPD patients receiving NIV, compared with NCO, HFNC during breaks from NIV can shorten respiratory support time and length of ICU stay, and improve carbon dioxide retention and dyspnea. HFNC is an ideal complement to NIV therapy in AECOPD patients.

Objective@#To evaluate the effect of the ischemic post-conditioning (IPC) on the prevention of the cardio-renal damage in patients with acute ST-segment elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PPCI).@*Methods@#A total of 251 consecutive STEMI patients underwent PPCI in the heart center of Tianjin Third Central Hospital from January 2012 to June 2014 were enrolled in this prospective, randomized, control, single-blinded, clinical registry study. Patients were randomly divided into IPC group (123 cases) and control group (128 cases) with random number table. Patients in IPC group underwent three times of inflation/deflation with low inflation pressure using a balloon catheter within one minute after culprit vessel blood recovery, and then treated by PPCI. Patients in control group received PPCI procedure directly. The basic clinical characteristics, incidence of reperfusion arrhythmia during the procedure, the rate of electrocardiogram ST-segment decline, peak value of myocardial necrosis markers, incidence of contrast induced acute kidney injury(CI-AKI), and one-year major adverse cardiovascular events(MACE) which including myocardial infarction again, malignant arrhythmia, rehospitalization for heart failure, repeat revascularization, stroke, and death after the procedure were analyzed between the two groups.@*Results@#The age of IPC group and control group were comparable((61.2±12.6) vs. (64.2±12.1) years old, P=0.768). The incidence of reperfusion arrhythmia during the procedure was significantly lower in the IPC group than in the control group(42.28% (52/123) vs. 57.03% (73/128), P=0.023). The rate of electrocardiogram ST-segment decline immediately after the procedure was significantly higher in the IPC group than in the control group (77.24% (95/123) vs. 64.84% (83/128), P=0.037). The peak value of myocardial necrosis markers after the procedure were significantly lower in the IPC group than in the control group(creatine kinase: 1 257 (682, 2 202) U/L vs. 1 737(794, 2 816)U/L, P=0.029; creatine kinase-MB: 123(75, 218)U/L vs.165(95, 288)U/L, P=0.010). The rate of CI-AKI after the procedure was significantly lower in the IPC group than in the control group(5.69%(7/123) vs. 14.06%(18/128), P=0.034). The rate of the one-year MACE was significantly lower in the IPC group than in the control group(7.32%(9/123) vs. 15.63% (20/128), P=0.040).@*Conclusion@#The IPC strategy performed eight before PPCI can reduce myocardial ischemia- reperfusion injury, decline the rates of CI-AKI and one-year MACE significantly in STEMI patients, thus has a significant protective effect on heart and kidney in STEMI patients.
