ABSTRACT
Objective To investigate the efficacy of sacubitril/valsartan combined with sodium ni-troprusside in treatment of acute heart failure(AHF)in elderly patients.Methods A total of 280 elderly AHF patients admitted in our hospital from June 2020 to June 2021 were enrolled and ran-domly divided into control group(143 cases,sodium nitroprusside treatment)and observation group(137 cases,sodium nitroprusside+sacubitril/valsartan).Their indicators in hemodynamics,cardiac function and vascular endothelial function,neurohormone factors and clinical total effec-tive rate were compared between 2 groups.Results After treatment,the observation group ob-tained significantly lower central venous pressure,mean arterial pressure,pulmonary vascular re-sistance,peripheral vascular resistance,left ventricular end-diastolic diameter,left ventricular end-systolic diameter,left ventricular end systolic volume,and levels of endothelin 1,N-terminal-type B natriuretic peptide precursor and noradrenaline,but higher LVEF and NO levels than the con-trol group(P<0.01).The total effective rate was statistically higher(97.08%vs 86.71%,P=0.002),but the incidence of adverse reactions was notably lower(11.68%vs 20.98%,P=0.036)in the observation group than the control group.Conclusion The combined treatment reduces he-modynamic indicators and neurohormone factors,and regulates the cardiac function and vascular endothelial function in elderly AHF patients.It is superior to sodium nitroprusside monotherapy with better total effectiveness but lower incidence of adverse reactions.
ABSTRACT
Perinatal loss is one of the most serious childbirth trauma,which seriously affects maternal physical and mental health.At present,the management strategy of maternal lactation can be divided into two aspects:milk return and milk donation.Breast milk donation may build new values of perinatal loss,which can promote maternal physical and mental recovery.This article reviewed the conception,status,motivations,facilitators,barriers and interventions of lactation management in women following perinatal loss,so as to provide bases for improving the awareness of obstetric nursing staff,quality of obstetric care and future research on lactation management in women following perinatal loss in China.
ABSTRACT
Objective:To investigate the role of integrin-linked kinase (ILK)-small interfering RNA (siRNA)-adeno-associated virus (AAV) in scar formation after glaucoma filtering surgery in rat eyes.Methods:Forty-eight Sprague Dawley rats of SPF grade, aged 8 to 9 weeks old, were selected and divided into blank control group, ILK-siRNA-AAV group, NC-siRNA-AAV group and mitomycin C (MMC) group by random number table method, with 12 rats in each group.Left eyes of the rats were taken as experimental eyes, and no intervention was administered to fellow eyes.The bulbar conjunctival filtering bleb after glaucoma filtration surgery in rats was established by anterior chamber drainage tube implantation.One day after operation, phosphate buffer solution, ILK-siRNA-AAV, and NC-siRNA-AAV were injected into the filtering bleb of blank control group, ILK-siRNA-AAV group and NC-siRNA-AAV group, 5 μl each group, respectively.Cotton tablets containing 0.4 mg/ml MMC were placed under conjunctival flap for 5 minutes during operation in MMC group.Intraocular pressure (IOP) was measured with a handheld tonometer before surgery and at 1, 2, 3, 7, 14, 21, 28 days after surgery.Formation of filtering blebs in rats was observed with a surgical microscope at 1, 2, 3, 7, 14, 21, 28 days after operation, and the bleb survival time was calculated by Kaplan-Meier survival analysis.The mRNA and protein expression levels of ILK in conjunctival and subconjunctival tissues at the surgical sites were detected by reverse transcription PCR and Western blot, respectively, on the 28th day after operation.Silencing of ILK gene was identified.Effect of ILK gene silencing on the morphology of drainage pathway was observed by hematoxylin-eosin staining.Effect of ILK gene silencing on collagen fiber deposition in the bulbar conjunctiva at filtration area was examined by Masson staining, and the percentage of positive area of collagen fiber staining in the total tissue visual field was calculated.The use and care of the animals complied with the ARVO Statement.This research protocol was approved by an Ethics Committee of Xi'an Jiaotong University (No.2013-772). Results:There were statistically significant differences in IOP at different time points between before and after surgery among four groups ( Fgroup=76.84, P<0.001; Ftime=114.49, P<0.001). The IOP of ILK-siRNA-AAV group on the 1st, 7th, 14th and 28th day after operation and the IOP of MMC group on the 2nd, 3rd, 7th, 14th and 28th day after operation were lower than those of blank control group, and the differences were statistically significant (all at P<0.05). The IOP of ILK-siRNA-AAV group was lower on 7th, 14th, 21st and 28th day after operation than those of NC-siRNA-AAV group, with statistically significant differences (all at P<0.05). The bleb survival time of blank control group, NC-siRNA-AAV group, ILK-siRNA-AAV group and MMC group was (3.50±1.51), (5.00±3.41), (31.50±3.15) and (31.33±2.46) days, respectively, with a significant difference among them ( F=395.83, P<0.05). The bleb survival time of ILK-siRNA-AAV group and MMC group was higher than that of blank control group and NC-siRNA-AAV group, and the differences were statistically significant (all at P<0.05). There were statistically significant differences in the relative expression levels of ILK mRNA and protein among four groups ( F=222.32, 752.69; both at P<0.05), and the relative expression levels of ILK mRNA and protein were significantly lower in ILK-siRNA-AAV group than blank control group and NC-siRNA-AAV group, and the differences were statistically significant (all at P<0.05). Proliferative fibrous connective tissue and a large number of cells at surgical sites were found in blank control group and NC-siRNA-AAV group, and the fibroblasts were of a high density and grew in clumps.In ILK-siRNA-AAV group, the bulbar conjunctiva was thin, and the arrangement of fibrous connective tissue was loose, and a few proliferative fibroblasts were found.In MMC group, the conjunctival fibrous layer was loose and thin, forming cavities, and scarce cells were found.There was statistically significant difference in the percentage of collagen fiber positive staining area among four groups ( F=741.66, P<0.05). The positive staining percentage of ILK-siRNA-AAV group and MMC group was significantly lower than that of blank control group, among which there was lower positive staining percentage in ILK-siRNA-AAV group than NC-siRNA-AAV group, and the differences were statistically significant (all at P<0.05). Conclusions:Silencing of ILK can inhibit the scar formation after glaucoma filtering surgery and maintain low IOP in rats.

ABSTRACT
OBJECTIVE:To screen the formulation of 5-fluorouracil (5-FU) polylactic acid (PLA) sustained-release discs (5-FU-PLA-DS),and study its in vitro drug-release mechanism. METHODS:UV spectrophotometry was used to determine the 5-FU content in the release medium. Using simulate body fluid as release medium,in vitro drug-release test was conducted under 37℃water bath. Using PLA with molecular weight of 3000,6000,10000,15000,20000,15 species of round 5-FU-PLA-DS with drug containing of 1.5,2.5,3.0 mg/piece and 3.0 mm in diameter and 1.0 mm in thickness were prepared. Using effective con-centration sustained release time and cumulative release rate as indexes, the optimal formulation was screened. The form of 5-FU-PLA-DS was observed by scanning electron microscopy after release,and its release mechanism was evaluated. RESULTS:In the optimal formulation, the PLA molecular weight was 20000 and drug containing was 3.0 mg/piece. The prepared 5-FU-PLA-DS can release for 119 d,with cumulative release degree of 100.63% and effective concentration sustained for 91 d. Scanning electron microscopy showed that the microspheres at the surface were degraded to the release medium first,and then the microspheres of inner layer exposed and release drug gradually after PLA degraded. The main mechanism of drug-release was melt-ing and diffusion. CONCLUSIONS:5-FU-PLA-DS is successfully prepared,with long release time in effective concentration,can be degraded step by step from outside to inside and achieve non-synchronous drug-release of microspheres at different layers.

ABSTRACT
Objective To investigate the biological behavior and expression of intergrin-linked kinase (ILK) after exposure to transforming growth factor beta 2 (TGF-β32) in human Tenon fibroblasts (HTFs).Methods The primary ceils of HTFs were cultured by tissue attached culture method and identified by immunofluorescence analysis with Vimentin and keratin.The proliferation levels of HTFs induced by different concentrations of TGF-β2 were analyzed by MTT.The α-smooth muscle actin (α-SMA) and ILK mRNA expression were analyzed by quantitative Real-time PCR.The protein expression of α-SMA,ILK and E-cadherin were analyzed by Western Blot,and the protein expression of α-SMA and E-cadherin were also analyzed by immunofluorescence staining.Results MTT analysis showed that the optical density levels of 5.0 μg · L-1 and 10.0 μg · L-1 TGF-β2 were significantly higher than those of 0.1 μg · L 1,1.0 μg · L-1 and the control after exposure for 48 hours and 72 hours,and all these optical density levels were significantly higher than that for 24 hours (all P <0.05).The expression of α-SMA and ILK mRNA increased significantly when cells were treated with 5.0 μg · L-1 TGF-β2 for 48 hours in comparison with the control group (all P < 0.05).The protein of α-SMA,ILK and E-cadherin were expressed both in TGF-β2 treated groups and control group,and TGF-β2 up-regulated the expression of them.There were significant differences when compared with the control group (all P < 0.05).Immunofluorescent staining showed that α-SMA and E-cadherin were detected in TGF-β2 treated groups.α-SMA expressed in cytoplasm,while E-cadherin both in cytoplasm and nucleus.Conclusion TGF-β2 can induce the proliferation,transdifferentiation and adhesion of HTFs,and up-regulate the expression of ILK in vitro,suggests that ILK may play a role in the process of scar formation after glaucoma filtration surgery.
ABSTRACT
Objective To observe the effect of risperidone on serum brain derived neurotrophic factor ( BDNF) in first-episode schizophrenic patients. Methods In the treatment group, 90 first-episode schizophrenics were treated with risperidone for 16 weeks, and the dose of risperidone was (3.79±0.88) mg·d-1. Serum BDNF levels were measured before treatment, at 2, 8, and 16 weeks after treatment. The severity of schizophrenia symptoms was assessed by the positive and negative symptom scale ( PANSS) before and after sixteen weeks of treatment. Serum BDNF concentrations were measured in 90 healthy controls. Results BDNF in the control group was (22.867±6.051) ng·mL-1. The serum BDNF levels before treatment and at the end of week 2, 8, 16 after the treatment in the treatment group were (14.256±4.096), (13.078±3.462), (18.001±5.753), (21.089± 6.692) ng·mL-1 , and the serum BDNF level was significantly lower in the treatment group than that in the control group ( P<0.01) . After the treatment, the level of BDNF in the treatment group decreased at first and then increased, compared with that before treatment, the difference was significantly ( P<0.05 or P<0.01) . The level of BDNF in the treatment group at the end of week 16 was not significantly different from that of the control group ( P>0.05) . After treatment, the total score of PANSS scale and its subscales decreased, the difference was significantly (P<0.01). At the end of week 16, the PANSS subscale reduction rate was positively correlated to the serum BDNF concentration change (r=0.499, P=0.001). The change rate of serum BDNF concentration at the end of week 16 was not correlated with the dose of risperidone (r=0.103, P=0.335). Conclusion BDNF is abnormal in the first episode of schizophrenia, which can be improved by risperidone treatment.

ABSTRACT
Objective To research the risk factors of new-onset atrial fibrillation (AF) during hospitalization in patients with acute myocardial infarction.Methods Five hundred and one patients first diagnosed with acute ST-segment elevation myocardial infarction who accepted primary coronary intervention from January 2012 to May 2014 in the Second Hospital of Tianjin Medical University were selected.These patients were divided into non-AF group and new-onset AF group depending on whether happened new-onset AF during hospitalization.Data of the patients in acute myocardial infarction complicated with new-onset atrial fibrillation were collected.Univariate and multivariate logistic regression analysis were used to determine the predictors of new-onset AF.Results AF occurred in 49 cases of the 501 (9.8%) patients diagnosed as acute myocardial infarction.Logistic regression analysis showed that admission heart rate(OR =1.019,95%CI:1.004-1.034,P =0.012),left atrial diameter (OR =1.086,95% CI:1.021-1.156,P =0.009),previous stroke (OR =2.060,95% CI:1.029-4.123,P =0.041) were independent risk factors for new-onset AF in acute myocardial infarction.Use of β-blockers before coronary intervention treatment can reduce the risk of new-onset atrial fibrillation(OR=0.222,95%CI:0.064-0.768,P=0.017).Conclusion Admission heart rate and left atrial diameter are independent predictors of new-onset atrial fibrillation,and β-blockers in early stage can effectively reduce the incidence of atrial fibrillation.
ABSTRACT
Objective To compare the differences of prescription pattern, adverse events, economic burden and drug-use adherence between preferred mood stabilizers and preferred antipsychotics in patients with bipolar disorder. Methods We investigated 240 cases of patients with bipolar disorder from 39 mental health institutions in 11 cities in Hebei province. The self-made questionnaire was used to investigate the demographic information, disease characteris-tics, prescription pattern and medical expense. The clinical global impression scale-severity of illness (CGI-SI) was used to assess the disease severity. The treatment emergent symptom scale (TESS) was used to assess the adverse drug reac-tions. The medication adherence rating scale (MARS) was used to assess drug therapy compliance in patients. Results One hundred fifty-two patients (63.3%) used antipsychotics as the first choice (antipsychotics group), 88 patients (36.7%) used mood stabilizers as the first choice (mood stabilizers group). The number of patients in-patient (90.1%vs. 76.1%), patients with psychotic symptom (27.0%vs. 11.4%), incidences of adverse events (46.1%vs. 31.8%), drug daily cost (me-dians 12.00 yuan vs. 8.37 yuan) and drug total cost (medians 344.61 yuan vs. 144.64 yuan) were larger in antipsychotics group than in mood stabilizers group (P0.05). Conclusion The bipolar disorder patients more frequently use antipsychotics as the first choice in Hebei province. The use of antipsychotics does not alter the combina-tion medication pattern. In addition, antipsychotics cause a higher incidence of adverse events and heavier economic bur-den compared with mood stabilizers, suggesting that mood stabilizers should be the first choice to bipolar disorder.
ABSTRACT
Objective To investigate the predictive value of CHADS2 and CHA2DS2-VASc score in left atrial (LA) or left atrial appendage (LAA) thrombus in patients with non-valvular atrial fibrillation (AF). Methods A total of 164 consecu?tive non-valvular AF patients confirmed by transesophageal echocardiography (TEE) were included in this study, and were divided into two groups, LA/LAA thrombus group and non LA/LAA thrombus group. The previous history was recorded in two groups of patients. Their CHADS2 and CHA2DS2-VASC scores were calculated based on the general data of two groups. The laboratory examinations and TEE indexes were compared between two gropes. Results Of all patients, the rate of LA/LAA thrombus was 19.5%. The CHADS2 and CHA2DS2-VASC scores were significantly higher in LA/LAA thrombus group than those of non LA/LAA thrombus group (2.1±1.3 vs 1.0±0.9, 3.4±1.8 vs 1.9±1.4,P<0.01). There were 13(11.9%) and 5 (8.8%) patients showed LA/LAA thrombus under low-moderate risk in the two score systems, respectively. Multivariate logis?tic regression analysis showed that CHADS2 score≥2 points(OR=3.735, 95%CI:1.508-9.251, P=0.004) and CHA2DS2-VASc score ≥2 points (OR=5.104, 95%CI:1.586-16.425, P=0.006) were independent risk factors of LA/LAA thrombus. ROC curve showed that AUC of CHADS2 and CHA2DS2-VASc scores to predict LA/LAA thrombus were 0.731 (95%CI:0.630-0.832, P<0.001) and 0.742 (95%CI:0.640-0.843, P<0.001), respectively. Conclusion CHADS2 and CHA2DS2-VASC score ≥2 points are independent risk factors of LA/LAA thrombus in patients with non-valvular atrial fibrillation. The pre?dictive values of both score systems are moderate. There are also LA/LAA thrombus in low-moderate risk patients when us?ing the two score systems, and with the increased risk stratification, the rate of LA/LAA thrombus is increased.
ABSTRACT
Objective:To test the validity and reliability of the Chinese version of the Br?set Violence Check-list (BVC-C).Methods:With the authorizing permission by the author,the BVC was translated into Chinese and a-dapted,and five psychiatry experts who had worked more than 20 years were invited (3 clinical doctors and 2 nur-ses)to evaluate the content validity of the scale as the content validity index.Totally 556 inpatients who met the di-agnosis criteria for mental disorders according to the International Statistical Classification of Diseases and Related Health Problems,Tenth Revision (ICD-10)were totally selected to proceed the formal testing.The BVC scale was used to evaluate inpatients every 8 hours,the Modified Overt Aggression Scale (MOAS)was used to test concurrent validity;the results of the real attacking incidents were used to test the criterion validity;the internal consistency re-liability of the scale was tested by Cronbach αcoefficient.Results:The content validity index of the scale was0.93.In addition to the own attack subscale,the MOAS total scores and the other 3 subscales scores were positively correlated with the BVC total scores and each item score (r =0.11 -0.69,P <0.01).The best criterion validity was 8 hours through analyzed,the AUC was 0.98.When the cut-off was 2,the sensitivity and specificity were 78.9% and 95.1% respectively.The Cronbach αcoefficient was 0.76 and the item total correlations were 0.47 -0.80 (P <0.01).Conclusion:It suggests that the BVC-C has good validity and reliability,which could be used as an effective prediction tool for psychiatric violence risk assessment.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between fragmented QRS complexes (fQRS) and imperfect ST-segment resolution in ST elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (p-PCI).</p><p><b>METHODS</b>This study included 227 consecutive patients with STEMI who underwent p-PCI. They were divided into two groups: ECG with fQRS (n = 142) and without fQRS (n = 85). Baseline clinical characteristics,Gensini score, coronary angiography features and the rate of ST-segment resolution were compared between the two groups.</p><p><b>RESULTS</b>(1) Patients with fQRS of ECG had higher cTnI, CK, CK-MB levels and Gensini score, prolonged QRS interval, lower rate of ST-segment resolution and left ventricular ejection fraction (LVEF) than in patients without fQRS (all P < 0.01 or P < 0.05). (2) Pearson correlation analysis showed that the rate of ST-segment resolution (r = -0.207, P = 0.002),Gensini score (r = 0.191, P = 0.004), LVEF(r = -0.188, P = 0.006), cTnI(r = 0.172, P = 0.010), and the TIMI grade post p-PCI (r = -0.148, P = 0.028) were significantly related with the presence of fQRS. (3) Multivariate logistic regression analysis demonstrated that presence of fQRS at pre-PCI (OR = 2.908, 95%CI:1.095-7.723, P = 0.032) , the number of leads with fQRS before PCI (OR = 1.582, 95%CI:1.250-2.002, P < 0.001), and increased QRS interval (OR = 0.955, 95%CI: 0.924-0.988, P = 0.008) were independent predictors of imperfect ST-segment resolution.</p><p><b>CONCLUSIONS</b>fQRS is related to imperfect ST-segment resolution in STEMI patients undergoing p-PCI.fQRS may be a useful parameter to identify the patients with severe coronary lesion, larger areas of ischemic injury and myocardial infarction as well as severe left ventricular contracted dysfunction.</p>
