ObjectiveTo investigate the protective effects of diisopropylamini dichlorocacetas on impairment of hepatic function in patients with sepsis. MethodsThe 60 inpatients with liver dysfunction and sepsis treated in our hospital between June 2010 and December 2012 were randomly divided into two groups: treatment group (n=30) and control group (n=30). In the treatment group, patients were treated with intravenous diisopropylamini dichlorocacetas for 7 days, while patients in the control group were treated with Vitamin C for the same period. The venous blood sample of each patient of the two groups was collected and examined for the content of alanine aminotransferase, aspartate aminotransferase, glutamyl transpeptidase, alkaline phosphatase, total bilirubin, and direct bilirubin before and after treatment, and the effective rates of the two groups were determined. ResultsLiver function indicators after treatment of both the two groups were reduced. Compared with the control group, the liver function indicators were significantly decreased and the total effective rate was significantly higher in the treatment group (P<0.05). ConclusionDiisopropylamini dichlorocacetas is effective in the treatment of impairment of hepatic function in patients with sepsis.
ObjectiveTo systematically review the efficacy of repetitive transcranial magnetic stimulation (rTMS) on patients with mild cognitive impairment (MCI). MethodsWe searched databases including PubMed, The Cochrane Library (Issue 10, 2015), EMbase, PsycINF, EBSCO, CBM, CNKI, WanFang Data and VIP from inception to October 2015 to collect randomized controlled trials (RCTs) about rTMS for patients with MCI. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software. ResultsA total of 5 RCTs involving 180 MCI patients were included. The results of meta-analysis showed that, compared with the control group, rTMS treatment could significantly improve the overall cognitive abilities of MCI patients (SMD=2.53, 95% CI 0.91 to 4.16, P=0.002), as well as the single-domain cognitive performances, including tests for episodic memory (MD=0.98, 95% CI 0.24 to 1.72, P=0.01) and verbal fluency (MD=2.08, 95% CI 0.46 to 3.69, P=0.01). rTMS was a well-tolerated therapy, with slightly more adverse events observed than the control group (RD=0.09, 95% CI 0.00 to 0.18, P=0.04), but cases were mainly transient headache, dizziness and scalp pain. ConclusionrTMS may benefit the cognitive abilities of MCI patients. Nevertheless, due to the limited quantity and quality of included studies, large-scale, multicenter, and high quality RCTs are required to verify the conclusion.
Objective To explore the related factors of upper urinary tract deterioration (UUTD) in spinal cord injury patients using intermittent catheterization (IC-SCI) in the community. Methods Patients with spinal cord injury in the Chinese community were selected for investigation between August 3 and August 31, 2020. The included patients were divided into UUTD group and non-UUTD group. The basic information, intermittent catheterization practices, and urinary complications were compared between the two groups. Logistic regression was used to analyze the risk factors contributing to UUTD. Results A total of 431 patients were surveyed. Among them, there were 310 males and 121 females, 246 cases in the non-UUTD group and 185 cases in the UUTD group. There were statistically significant differences in the disease duration, gender, etiology, urinary incontinence, urinary tract infection, bladder calculi and nephrolithiasis between the two groups (P<0.05); there was no statistically significant difference in the other indicators between the two groups (P>0.05). The results of logistic regression analysis showed that urinary tract infection [odds ratio (OR)=3.229, 95% confidence interval (CI) (1.706, 6.110), P<0.001], nephrolithiasis [OR=4.846, 95%CI (2.617, 8.973), P<0.001], and urinary incontinence [OR=2.345, 95%CI (1.116, 4.925), P=0.024] were risk factors for UUTD. Conclusion Urinary tract infection, nephrolithiasis and urinary incontinence are independent risk factors for UUTD in community-based IC-SCI patients and deserve attention for preventive strategies.
目的 测定多发性骨髓瘤（MM）患者血清胱抑素C （Cys-C） 的水平，探讨Cys-C与国际分期体系（ISS）、血β2-微球蛋白、溶骨性损害等指标的关系。 方法 收集2008年1月－2010年9月32例初治和8例复发的MM患者作为研究对象，同时收集40例健康体检者的检查资料作为对照组，测定血清Cys-C、血肌酐（Scr）、血β2-微球蛋白。采用核素全身骨显像（ECT）观察患者的溶骨性病变部位数。 结果 患者血清Cys-C水平（1.40 mg/L）明显高于健康对照组（0.90 mg/L）（P＜0.01）；在MM患者中Cys-C比Scr更敏感，能反映肾小球滤过率；血清Cys-C水平与ISS分期晚，血β2-微球蛋白升高以及溶骨性病变进展密切相关。 结论 MM患者的Cys-C水平高于健康者。Cys-C是骨髓瘤肾损害的早期敏感标志物，与肿瘤负荷及溶骨性损害密切相关，可作为评价肿瘤负荷的潜在指标。Objective To evaluate the serum levels of cystatin-C in patients with multiple myeloma (MM), and to explore its possible correlations with clinical data, including ISS stage, serum β2-microglobulin, and advanced lytic lesions. Methods From January 2008 to September 2010, serum cystatin-C, creatinine (Scr), and β2-microglobulin in 32 patients with MM, 8 patients with relapsed disease, and in 40 healthy controls were detected by automatic biochemistry analyzer detection. According to skeleton ECT, grading of osteolytic lesion was observed. Results The levels of serum cystatin-C of patients with MM were significantly higher than those of the controls. Serum cystatin-C could reflect the glomerular filtration rate , and was more sensitive than Scr in patients with renal lesion. Serum cystatin-C had ber correlations with advanced ISS stages, high levels of serum β2-microglobulin, and extensive bone diseases. Conclusion Serum cystatin-C is a sensitive marker of renal lesion in patients with MM, it could be a potential indicator to assess the tumor burden.
This study seeks to explore the early signs of cognitive impairment in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). According to polysomnography, twenty patients diagnosed with OSAHS and twenty normal controls underwent event-related potential (ERP) examination including mismatch negativity (MMN) and P300. Compared with normal controls, OSAHS patients showed significantly prolonged latency of MMN and P300 at Cz. After controlling age and body mass index (BMI), MMN latency positively correlated with apnea hypopnea index (AHI), oxygen reduction index, stage N1 sleep and arousal index, while MMN latency negatively correlated with stage N3 sleep and mean blood oxygen saturation; and P300 latency positively related to AHI and oxygen reduction index; no relationships were found among MMN latency, MMN amplitude, P300 latency and P300 amplitude. These results suggest that the brain function of automatic processing and controlled processing aere impaired in OSAHS patients, and these dysfunction are correlated with nocturnal repeatedly hypoxemia and sleep structure disturbance.
Objective To evaluate the safety of Rongbisu capsule used for treating benign prostatic hyperplasia. Methods A total of 218 patients (average age 63.73±7.50 years old) with phase Ⅰor Ⅱ benign prostatic hyperplasia were treated with oral Rongbisu capsule at a dose of 3 granules twice daily. The therapeutic course was 6 weeks and hepatic function was determined every 2 weeks. Results The median value of ALT in 218 patients rose significantly after the patients took Rongbishu capsule for 6 weeks (P=0.001 7). There were 17 patients whose ALT level rose from normal to abnormal, the incidence was 7.80%. There were 3 patients whose hepatic function was seriously impaired (ALT＞200 IU/L). Conclusions The essential component of Rongbishu capsule is edible tulip which has been recorded in the medical literature as being toxic. Airpotato yam of which the alias is also edible tulip is easily mistaken for edible tulip. Airpotato yam is the tuber of dioscorea bulbifera L. (family dioscoreaceae) which has confirmed hepatotoxcity. Our study result indicates that in order to insure the safety of Chinese crude drug, the origin of Chinese crude drug should be defined in the formulation according to the standard of Chinese drugs preparation. Pharmaceutical enterprises should strictly abide by the standards to identify the origin of Chinese crude drugs when approving the raw materials, especially for species which are poisonous and easily mistaken.
Cognitive impairment is one of the three primary symptoms of schizophrenic patients and shows important value in early detection and warning for high-risk individuals. To study the specifics of electroencephalogram (EEG) in patients with schizophrenia under the cognitive load, we collected EEG signals from 17 schizophrenic patients and 19 healthy controls, extracted signals of each band based on wavelet transform, calculated the characteristics of nonlinear dynamic and functional brain networks, and automatically classified the two groups of people by using a machine learning algorithm. Experimental results indicated that the correlation dimension and sample entropy showed significant differences in α, β, θ, and γ rhythm of the Fp1 and Fp2 electrodes between groups under the cognitive load. These results implied that the functional disruptions in the frontal lobe might be the important factors of cognitive impairments in schizophrenic patients. Further results of the automatic classification analysis indicated that the combination of nonlinear dynamics and functional brain network properties as the input characteristics of the classifier showed the best performance, with the accuracy of 76.77%, sensitivity of 72.09%, and specificity of 80.36%. The results of this study demonstrated that the combination of nonlinear dynamics and function brain network properties may be potential biomarkers for early screening and auxiliary diagnosis of schizophrenia.
