Objective:To observe the efficacy of polyene phosphatidyl choline combined with Hugan tablets in the treatment of drug-induced liver injury. Methods:Totally 80 cases of drug-induced liver injury were randomly divided into the observation group (40 cases )and the control group(40 cases). The observation group was given polyene phosphatidyl choline injections 697. 5mg+5%glucose injections 250ml,ivd,qd,combined with Hugan tablets 1. 44g,po,tid,the control group was given polyene phosphatidyl choline injections 697. 5mg+5%glucose injections 250ml,ivd,qd,and the symptomatic treatment in the two groups was the same. The two groups were treated for 20d. Alanine aminotransferase ( ALT), aspartate aminotransferase ( AST), total bilirubin ( TBIL), glutamyl transpeptidase(GGT) and alkaline phosphatase(ALP)were detected respectively before and after the treatment, and the therapeutic effects were compared between the two groups. Results: After the treatment,the total effective rate in the observation group was 97. 5%,which was significantly higher than that in the control group(P <0. 01),Symptoms,signs and biochemical indices in the two groups were improved obviously. The decrease of ALT,AST and GGT in the observation group after the treatment was obviously lower than that in the control group(P<0. 05). Conclusion: Polyene phosphatidylcholine injections combined with Hugan tablets in the treatment of liver injury is better than polyene phosphatidyl choline, which is worthy of clinical application.

To reveal the anti-inflammation mechanism of koumine,we determined effects of different concentrations of koumine(100,200,400 mg/L) on the secretion of NO,IL-1β,IL-6 and TNF-a by nitrate reductase and ELISA as well as the mRNA of iNOS,IL-1β,IL-6 and TNF-α.Western blot was used to detect iNOS protein expression.The results showed that 100,200,400 mg/L of koumine can significantly inhibit the secretion of NO,IL-1β,IL-6 and TNF-α of RAW264.7 cell (P＜0.01).Koumine can dose-dependently down-regulate the mRNA of iNOS,IL-1β,IL-6 and TNF-α,meanwhile koumine can also significantly inhibit the protein expression of iNOS.The results indicated that koumine may play an anti-inflammation activity by mean of the reduction of NO and mediator of inflammation,down-regulating the mRNA expression of iNOS,IL-1β,IL-6 and TNF-a,decreasing protein expressions of iNOS.

The basic characteristic of the functional neuromuscular stimulation signals suitable to body is preliminarily determined after the fatigue performance of the biceps, and the physiological reaction to stimulation is investigated using many continuous stimulation signal patterns. The flexion motion of the elbow joint (right hand) of a healthy man was taken as our research objective. The surface electrodes were connected to the biceps and a micro angle sensor was mounted on the elbow joint (right hand). The curves of angular displacement for the elbow joint motion were obtained by using functional neuromuscular stimulation (FNS) limbs motion measurement instruments. The results demonstrate that the biceps are characterized by the non-linear and time-variant no matter what the stimulation patterns are, that continuous slow stimulation signals can reduce the muscle fatigue of the biceps, and that the stimulation frequencies ranging from 30 Hz to 50 Hz are applicable to the neuromuscular system.

ObjectiveTo evaluate the application of multi-slice CT (MSCT) perfusion scan technique in predicting renal function recovery after unilateral hydronephrosis treatment.MethodsThirtyeight patients with unilateral obstructive hydronephrosis not shown on intravenous urography (IVU) and a normal contralateral kidney were recruited for this study.Patients were divided into detected (D) and undetected (UD) groups depending on whether the IVU detected urinary tract obstruction.All patients underwent plain abdominal X-ray,gray-scale ultrasonography,excretory urography and MSCT perfusion scan before and after the treatment.Patients were followed-up at six months or more after the treatment for a mean duration of 12.5 months (range from 6 to 22 ).ResultsOf the 38 cases,22 cases were in group D,16 cases were in group UD.On MSCT,renal cortex blood flow (BF) and blood volume ( BV ) value after treatment in group D were 561.1 ± 165.4 ml/( 100 g · min) and 35.9 ± 11.3 ml/100 g compared with before treatment rates of 361.6 ±109.7 ml/(100g· min) and24.1 ±10.2 ml/100g,t=-3.38,-2.34,P＜0.01,0.05.In the UD group,the differences of these parameters were after treatment 38.7 ± 15.4 ml/(100 g · min),10.306 ± 4.925 ml/100 g and before treatment 39.1 ± 22.5 ml/( 100 g · min) and 8.7 ± 4.4 ml/100 g,P ＞ 0.05.In the aspects of BF and BV,there were statistically significant differences between group D and group U D both before and after the treatment,t=9.09,4.15,P ＜ 0.01.ConclusionsM SCT perfusion can provide a valuable prediction technique of the renal function recovery in patients with unilateral obstructive hydronephrosis.Improvement of renal function can be expected after relief of obstructive hydronephrosis if the patients have a BF 361.6 ml/( 100 g · min) and BV 24.1 ml/100 g or greater measured by MSCT perfusion.

Objective:To analyze the efficacy and safety of enzyme therapy in late-onset Pompe disease (LOPD) patients, so as to provide reference for the treatment and prognosis of LOPD.Methods:The effect of α-glucosidase (GAA) on a patient diagnosed with LOPD in the Affiliated Hospital of Jining Medical University was observed and analyzed. Besides, literature related to enzyme therapy in LOPD patients were searched in PubMed, Web of Science, Medline databases. Twenty-one studies containing clinical data from 910 LOPD patients related to enzyme therapy were finally included for analysis.Results:The patient developed muscle weakness since he was 16 years old. The GAA activity in peripheral blood was 0. Electromyography suggested myogenic lesions in both lower extremities. Compound heterozygous mutations of GAA gene were found by next- generation sequencing. Muscle biopsy revealed characteristic vacuolar changes. After eight years of diagnosis, the patient was given enzyme therapy for 18.5 months, 20 times in total. The symptoms of muscle weakness were slightly improved in the early stages of treatment without obvious adverse reactions. Most of the 910 LOPD patients were stabilized or had improved muscular and (or) respiratory function following treatment with GAA.Conclusion:GAA treatment is effective and well tolerated. In patients with advanced severe LOPD, enzyme replacement therapy remains effective even years after onset.

Objective:To explore the effects of behavior intervention on patients with ischemic cerebrovascular disease recurrence, carotid artery stenosis recurrence, and quality of life after carotid artery stenting implantation.Methods:Sixty patients with carotid stenosis who underwent stenting surgery between January 2017 and July 2018 in Affiliated Hospital of Jining Medical University were recruited.The subjects were randomly divided into behavioral intervention group and control group.The control group was routinely followed up after carotid artery stenting implantation.The behavioral intervention group added home visit, education, guidance of the control and detection of risk factors for cerebrovascular disease of stent implantation.Results:After 12 months of intervention, the incidence of ischemic cerebrovascular disease and the recurrence rate of carotid restenosis in the behavioral intervention group(6.7%, 3.3%) were significantly lower than those in the control group(30.0%, 20.0%) (both P<0.05). Six months after the intervention and 12 months after the intervention, the self-management ability score (intervention group: six months after the intervention (171.20±18.43), 12 months after the intervention (179.90±14.34); control group: six months after the intervention (160.77±13.43); 12 months after the intervention (164.27±14.85)) and quality of SS-QOL score (intervention group: 6 months after intervention (188.47±16.25), 12 months after intervention (203.17±13.84); control group: 6 months after intervention (170.67±15.82); 12 months after intervention (183.80±18.19)of the intervention group were higher than that of the control group, the difference is statistically significant (all P<0.05). Conclusion:Behavioral intervention after carotid artery stenting implantation can effectively reduce the incidence of stroke and the recurrence rate of carotid stenosis and improve the prognosis of patients.The mechanism may be related with that the behavioral intervention can improve the self-management ability and the quality of life of patients with carotid stenosis.

Cerebral amyloid angiopathy (CAA) is a common cerebral small vessel disease, mainly caused by β-amyloid deposition on the small vessels less than 200 μm in diameter in cortex and leptomeninges. CAA is a major cause of spontaneous intracerebral hemorrhage in the elderly, especially lobar location. Early symptoms are insidious, and as the disease progress, they manifest as cerebral hemorrhage, cognitive decline, transient focal neurological episodes, cerebral infarction, epilepsy, headache, etc. MRI revealed that CAA is a disease in which bleeding and ischemia coexist, and even inflammation and immune responses are involved. MRI findings of CAA include cerebral hemorrhage, cerebral microbleeds, convexity subarachnoid hemorrhage and cortical superficial siderosis, cortical microinfarcts, CAA-associated inflammation, white matter hyperintensities, enlarged perivascular spaces, cerebral atrophy and lacune, etc. The same patient often has several of the above manifestations, and each manifestation has different specificity for the diagnosis of CAA. The rapid development of MRI technology has led to the improvement of the diagnostic level of CAA, and it is of great clinical significance to understand these imaging findings. This article reviews the MRI findings of sporadic CAA.

Objective:To explore the correlation between serum levels of interleukin-9 (IL-9), platelet activating factor (PAF), total immunoglobulin E (IgE), interferon γ (IFN-γ), and interleukin-4 (IL-4) in patients with chronic spontaneous urticaria (CSU).Methods:Sixty CSU active phase patients admitted to the First Affiliated Hospital of Hebei North University from March 2018 to March 2019 were selected and included in the CSU active phase group. Based on the 7-day Urticaria Activity Score (UAS7), they were divided into three groups: 15 mild group, 25 moderate group, and 20 severe group; And 19 patients who entered the quiescent phase of the disease after 28 days of standardized antihistamine treatment were included in the CSU quiescent phase group. Another 30 healthy subjects who participated in the physical examination at the same time at our hospital′s physical examination center were selected to be included in the healthy control group. 5 ml of fasting elbow vein blood was collected from CSU active and stationary patients, as well as healthy subjects. The serum levels of IL-9, PAF, total IgE, IFN-γ, and IL-4 were detected using enzyme-linked immunosorbent assay. Pearson correlation test was used to analyze the correlation between serum IL-9, PAF levels and total IgE, IFN-γ, and IL-4 levels in CSU active patients.Results:The serum levels of IL-9, PAF, total IgE, and IL-4 in the CSU active phase group were higher than those in the CSU stationary phase group and healthy control group (all P<0.05), and the serum IFN-γ levels were lower than those in the CSU stationary phase group and healthy control group (all P<0.05). There was no statistically significant difference in the levels of the above indicators between the healthy control group and the CSU stationary group (all P>0.05). The serum levels of IL-9, PAF, total IgE, and IL-4 in the severe group were significantly higher than those in the mild and moderate groups (all P<0.05), and the serum IFN-γ levels were significantly lower than those in the mild and moderate groups (all P<0.05); The serum levels of IL-9, PAF, total IgE, and IL-4 in the moderate group were significantly higher than those in the mild group (all P<0.05), and the serum IFN-γ levels were significantly lower than those in the mild group ( P<0.05). Pearson correlation analysis showed that serum IL-9 and PAF levels were positively correlated with serum total IgE and IL-4 levels in CSU active phase patients (IL-9: r=0.726, 0.870, PAF: r=0.788, 0.795, all P<0.01), and negatively correlated with serum IFN-γ levels (IL-9: r=-0.831, PAF: r=-0.816, all P<0.01). Conclusions:The serum levels of IL-9 and PAF in patients with active CSU are elevated and correlated with total IgE, IFN-γ, and IL-4 levels, suggesting that IL-9 and PAF may be related to the occurrence and development of CSU.

Objective:To explore the relationship of serum interleukin (IL) -9 and platelet-activating factor (PAF) levels with serum total immunoglobulin E (IgE) levels, disease severity and disease course in patients with chronic spontaneous urticaria (CSU) .Methods:A total of 60 patients with active CSU were collected from Department of Dermatology, the First Affiliated Hospital of Hebei North University from March 2018 to March 2019 (active CSU group), and divided into mild group, moderate group and severe group according to 7-day urticaria activity score (UAS7). After 28-day standard antihistamine therapy, the patients whose condition became stable were included in the stable CSU group. During the same period, 30 health examinees were included in the healthy control group. Peripheral venous blood samples were collected from the subjects in each group, enzyme-linked immunosorbent assay (ELISA) was performed to detect serum levels of IL-9 and PAF, and immunoturbidimetric assay to detect the serum total IgE level. Correlations of serum IL-9 and PAF levels with serum total IgE levels, UAS7 scores and disease courses were analyzed in patients with CSU. One-way analysis of variance was used for comparisons among multiple groups, least significant difference- t test for multiple comparisons, and Pearson correlation analysis for correlation analysis. Results:Totally, 28 males and 32 females were included in the active CSU group, their age ranged from 11 to 68 years (34.68 ± 8.62 years), and the disease duration ranged from 2 months to 7 years (1.42 ± 0.41 years). In the healthy control group, 14 were males and 16 were females, and their age ranged from 10 to 70 years (35.06 ± 7.89 years). According to UAS7, 12, 26, and 22 patients were diagnosed with mild, moderate and severe CSU respectively, and 22 were included in the stable CSU group after standard treatment. The levels of serum IL-9, PAF and total IgE significantly differed among the active CSU group, stable CSU group and healthy control group (IL-9: 144.34 ± 23.19 vs. 109.25 ± 20.77 vs. 107.23 ± 19.23 pg/ml; PAF: 362.45 ± 51.45 vs. 223.18 ± 32.46 vs. 221.23 ± 28.38 pg/ml; total IgE: 168.12 ± 32.48 vs. 24.04 ± 7.04 vs. 21.76 ± 5.95 IU/ml; F = 38.80, 148.38, 499.12, respectively, all P < 0.001), and were significantly higher in the active CSU group than in the stable CSU group and healthy control group (all P < 0.05), while there was no significant difference between the stable CSU group and healthy control group (all P > 0.05). Pearson correlation analysis showed that the serum IL-9 and PAF levels were positively correlated with serum total IgE levels and UAS7 scores (all P < 0.05), but not correlated with the disease course (both P > 0.05) . Conclusion:Serum IL-9 and PAF levels in patients with active CSU were markedly elevated along with the increase in disease severity, and closely correlated with serum total IgE levels.
