ABSTRACT
With the widespread application of extracorporeal membrane oxygenation (ECMO) technology, ECMO centers have been established in most regions of China, and the demand for ECMO transport is also increasing. Critically ill patients with ECMO carry many catheters. ECMO devices and accessories are cumbersome and numerous, requiring a large amount of manpower to assist in the transfer. At present, most of ECMO transport equipment are vertical carts provided by equipment suppliers, which cannot accommodate all ancillary equipment and are difficult to be loaded into ambulances for transportation. Therefore, critically ill patients face many risks if they need to be transported inter-hospital. A specific vehicle for ECMO patients was designed by the medical staff of the department of critical care medicine of Zhujiang Hospital of Southern Medical University, which integrates the ECMO host, oxygenator, centrifugal pump, portable ventilator, coagulation instrument, injection pump, monitor, oxygen cylinder, and etc., to greatly facilitate the transportionation. This invention obtained the National Utility Model Patent of China (ZL 2019 2 1201261.4). The new ECMO transport vehicle can facilitate the interhospital transport of critically ill patients, reduce the occurrence of accidents, shorten the transport time and reduce the number of transport personnel, and has a good clinical application value.
ABSTRACT
Objective:To investigate the postnatal grading, surgical intervention and prognosis in fetal hydronephrosis.Methods:The clinical data of 243 children who were prenatally diagnosed with fetal hydronephrosis and first seen at Dalian Children′s Hospital after birth from November 2014 to November 2017 were retrospectively analyzed. All cases were followed up by routine ultrasound after birth and were assessed and graded according to the postnatal urinary tract dilation (UTD) system. The children with clinical indication for surgery underwent surgical treatment (operation group), and the children without clinical indication were closely followed up (non-operation group).Results:Among 243 children, 182 were male and 61 were female; the gestational age at first diagnosis was (27.5±3.2) weeks, and the maternal age was (29 ± 6) years; 212 cases were unilateral, and 31 cases were bilateral. The results of the first ultrasound examination result showed UTD low-risk was in 117 cases, medium-risk in 67 cases, high-risk in 59 cases. All the children were followed up from 14 to 50 months, with a mean of 26.4 months. During the follow-up period, 117 cases with UTD low-risk did not undergo surgical treatment; 62 cases of 67 with UTD medium-risk did not receive operation, and 5 were operated; while operation were performed on 56 cases of 59 with UTD high-risk, and 3 children with stable hydronephrosis were not treated surgically. The non-operation group had 182 cases, and operation group had 61 cases. The UTD high-risk rate and renal pelvis anteroposterior diameter of first ultrasound examination in operation group were significantly higher than those in non-operation group: 91.80% (56/61) vs. 1.65% (3/182) and 1.9 (1.6, 2.4) mm vs. 0.7 (0.3, 1.5) mm, the thickness of renal parenchyma was significantly lower than that in non-operation group: 3.0 (1.3, 4.1) mm vs. 6.0 (5.1, 7.2) mm, and there were statistical differences ( P<0.01 or <0.05). The result of follow-up in operation group showed that the renal pelvis anteroposterior diameter and the ratio of renal pelvis anteroposterior diameter to renal parenchyma thickness 1 year after operation were significantly lower than those before operation: (1.6 ± 0.7) cm vs. (3.5 ± 1.5) cm and 0.3 ± 0.2 vs. 1.1 ± 1.0, the thickness of renal parenchyma and differentiated renal function were significantly higher than those before operation: (5.8 ± 2.4) mm vs. (3.2 ± 3.1) mm and (45.4 ± 1.9)% vs. (39.5 ± 2.3)%, and there were statistical differences ( P<0.05). Conclusions:UTD grading system is required after birth. Children with hydronephrosis in UTD low-risk and most of the UTD medium-risk have relatively satisfactory prognosis. The hydronephrosis children with UTD high-risk should undergo early surgery if progressive worsening appears and decline in differentiated renal function is detected.
ABSTRACT
Objective:To investigate the clinical characteristics and prognosis of patients with cutaneous intravascular large B-cell lymphoma (IVLBCL).Methods:The data of 30 cutaneous IVLBCL published between January 1989 and May 2019 in China were systematically reviewed. The clinical manifestation, biochemical and imaging characteristics and diagnostic features of patients were summarized, and then the survival of different groups was also analyzed.Results:The median onset age was 61.5 years old (25.0-83.0 years old), and there were 22 (73.3%) females. All 30 patients presented with cutaneous lesions. Initial symptoms showed cutaneous lesions in 16 (53.3%) patients; and B symptom, respiratory symptoms or central nervous system (CNS) occurred in 14 (46.7%) patients with late cutaneous lesions. Cutaneous lesions were heterogeneous, and 76.7% (23/30) lesions located in lower abdomen and proximal limbs. And 76.2% (16/21) were positive in image examination, and 78.3% (18/23) had two or more extranodal organs invasion. The median time from onset to visit was 2.5 months (0.4-24.0 months), and clinical misdiagnosis rate was 56.7%(17/30). All IVLBCL patients were confirmed by biopsy, including 6 cases (27.3%, 6/22) of bone marrow involvement, 1 case (3.3%) of hemophagocytic syndrome-associated variant, and 29 cases (96.7%) of classical variant. Finally, 81.8% (18/22) patients received anthracycline-based combined chemotherapy. Compared with non-chemotherapy group, the median OS time of chemotherapy group was prolonged [11.0 months (2.0-60.0 months) vs. 2.0 months (0.7-24.0 months), P = 0.002]. Patients with CNS symptoms had shorter median OS time compared with patients without CNS symptoms [2.0 months (0.7-6.0 months) vs. 11.0 months (1.0-60.0 months), P < 0.01]. The median OS time in the group of cutaneous lesions as initial symptom combined with other symptoms was longer than that in group of late cutaneous lesions and other symptoms as initial symptom [unreached (2.0-60.0 months) vs. 3.0 months (1.5-24.0 months), P = 0.032]. Conclusions:Cutaneous IVLBCL is a rare disease with atypical clinical characteristics in China. Prompt attention and biopsy in time will be helpful for early diagnosis. Accompanied with CNS symptoms suggests poor prognosis; and timely chemotherapy can improve the prognosis of the patients.

Methods: A rat model of AD was established by bilateral hippocampus injection of Aβ1-42. Shenqi Yizhi granules were used for 60 days. Morris water maze was used to detect the learning and memory function of each rat. HE staining was used to observe the pathological changes of rat hippocampal CA3 area. Immunohistochemistry was used to detect the expression of PI3K and AKT protein in hippocampus. The relative expression levels of PI3K mRNA and AKT mRNA were detected by RT-PCR. Results: Compared with the blank group, the escape latency of the model group was significantly prolonged, and the number of entering the platform, the time and percentage of crossing the platform quadrant decreased significantly (P ＜ 0.05). At the same time, the vertebral cells in the hippocampal CA3 area were disordered and the neurons showed obvious lesions. PI3K/AKT showed significant inhibition at both protein and gene levels (P ＜ 0.05). After intervention with Shenqi Yizhi Granule, the escape latency of the model rats was significantly shortened, and the number of entering the platform and the time of crossing the platform quadrant were significantly increased (P ＜ 0.05). Conclusion: Shenqi Yizhi Granules can improve the cognitive function of Aβ1-42 bilateral hippocampus injection in AD rats, and its mechanism may be related to activation of PI3K/AKT signaling pathway in brain.
ABSTRACT
Alzheimer's disease (AD) is a complex neurodegenerative disease. Its pathogenesis involves many factors such as environment, heredity, aging, diet, personal preference and underlying diseases. And the complex pathogenic factors of AD lead to many social and economic problems such as delayed diagnosis, difficulty of drug research and development, low cure rate and high cost of care. In this paper, the relationship between AD disease progression and its risky diseases such as metabolic diseases, chronic inflammatory diseases and cardiovascular diseases was analyzed based on energy metabolism abnormalities. The role of energy metabolism signal/path abnormality activity in the course of risk disease to AD disease was analyzed. Finally, it is suggested that the prevention and treatment of risk disease evolution and adjustment of abnormal energy metabolism signals may be effective strategies for the treatment of AD.
ABSTRACT
ObjectiveTo investigate the prevalence of nonalcoholic fatty liver disease (NAFLD) in Haikou, China and the association of NAFLD with metabolic syndrome (MS) and its components. MethodsA total of 18771 persons who underwent physical examination in Haikou People’s Hospital from September 2016 to August 2017 were enrolled. Body height, body weight, blood pressure, fasting plasma glucose, blood lipids, and liver function parameters were measured, and ultrasound examination was performed for the liver. The prevalence rate of NAFLD was calculated, and the association of NAFLD with MS and its components was analyzed. The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. ResultsOf all 18771 persons, 5715 had NAFLD, resulting in a prevalence rate of 30.45%; the prevalence rate of NAFLD was 41.74% in men and 1722% in women. Men aged 45-59 years had the highest prevalence rate of NAFLD, and women aged ≥45 years had the highest prevalence rate. Men had a significantly higher prevalence rate of moderate NAFLD than women (8.10% vs 1.19%, χ2=476.1, P＜0.001). Men with obesity and overweight had a higher prevalence rate of NAFLD, and women with obesity had a higher prevalence rate; in both men and women, there was a significant difference in the prevalence rate of NAFLD between groups with different levels of body mass index (BMI) (χ2=2111，1917，all P＜0.001). NAFLD patients had significantly higher BMI, blood pressure, fasting plasma glucose, triglyceride, alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transpeptidase than non-NAFLD patients (t=41.276, 32.339, 31.487, 12.185, 9.716, 38.382, 26.350, 25.291, and 15.008, all P＜0.001).

ABSTRACT
Objective To explore the effect of regional synergistic treatment system on the treatment time and short-term prognosis of patients with ST-segment elevation myocardial infarction (STEMI).Methods A retrospective analysis of the clinical data of STEMI patients who admitted to emergency center of Suzhou Kowloon Hospital Affiliated to Shanghai Jiaotong University School of Medicine and underwent primary percutaneous coronary intervention (PPCI) from January 2013 to January 2017 were conducted. All patients were divided into two groups, group A was the patients who underwent the PPCI before the establishment of the acute chest pain area co-treatment system (from January 2013 to December 2014), and group B was the patients who received the treatment after the establishment of the area co-treatment system (from January 2015 to January 2017). The length of time from onset of symptoms to the balloon dilatation (S2B), the length of time from the first medical contact to the balloon dilatation (FMC2B), the length of time from entering the gate of hospital to the balloon dilatation (D2B), and the incidence of 90-day end point events (including heart failure, all-cause death, and other related adverse events) were collected. The relations of the establishment of the acute chest pain area co-treatment system and the incidence of 90-day end point events were analyzed by multivariable Logistic regression analysis.Results Among the 221 enrolled patients with STEMI, 83 patients were in group A and 138 patients were in group B respectively. Compared with group A, S2B time [minutes: 180 (140, 210) vs. 201 (154, 225)], FMC2B time [minutes: 89 (78, 100) vs. 94 (83, 107)] and D2B time [minutes: 66 (62, 70) vs. 85 (72, 99)] were significantly shortened in group B (allP < 0.05), the incidence of 90-day end point events were significantly decreased (heart failure:20.3％ vs. 32.5％, all-cause death: 1.4％ vs. 7.2％, other related adverse events: 23.2％ vs. 36.1％, allP < 0.05). It was shown by multivariable Logistic regression analysis that the establishment of the acute chest pain area co-treatment system could lower the incidence of 90-day end point events [heart failure: odds ratio (OR) = 1.904, 95％ confidence interval (95％CI) = 0.968-1.004, P = 0.048; all-cause death:OR = 11.724, 95％CI = 0.955-1.048,P = 0.013; other related adverse events:OR = 1.925, 95％CI = 1.049-3.530,P = 0.034].Conclusion The construction of regional synergistic treatment system can shorten the emergency treatment time of STEMI patients and reduce the incidence of 90-day end point events including heart failure and death.

ABSTRACT
ObjectiveTo investigate the clinical features of patients with acute exacerbation of chronic hepatitis B, and to provide a basis of evidence-based medicine for the diagnosis and treatment of acute exacerbation of chronic hepatitis B. MethodsA retrospective analysis was performed for the clinical data of 74 patients with acute exacerbation of chronic hepatitis B who were diagnosed in The People′s Hospital of Haikou from January 2011 to October 2015. These patients were divided into HBeAg positive group (51 patients) and HBeAg negative group (23 patients). The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. ResultsThe patients with acute onset of chronic hepatitis B had a level of alanine aminotransferase (ALT) of 523-2940 U/L and were manifested as icteric hepatitis (64 patients, 86.49%), and 65 patients (87.84%) were cured within 4 weeks. There were no significant differences in baseline ALT, aspartate aminotransferase, and HBV DNA levels between the HBeAg positive group and the HBeAg negative group (all P＞0.05), and the HBeAg negative group had a significantly higher level of total bilirubin (TBil) than the HBeAg positive group (141.1±132.9 μmol/L vs 80.1±68.8μmol/L, t=2.745, P=0.007). ConclusionThe acute exacerbation of chronic hepatitis B is similar to acute hepatitis B, and the patients with negative HBeAg have a high level of TBil and severe hepatocyte injury.
ABSTRACT
Using of high throughput sequencing technology to study the microbial diversity in complex samples has become one of the hottest issues in the field of microbial diversity research. In this study, the soil and sheep rumen chyme samples were used to extract DNA, respectively. Then the 25 ng total DNA was used to amplify the 16S rRNA V3 region with 20, 25, 30 PCR cycles, and the final sequencing library was constructed by mixing equal amounts of purified PCR products. Finally, the operational taxonomic unit (OUT) amount, rarefaction curve, microbial number and species were compared through data analysis. It was found that at the same amount of DNA template, the proportion of the community composition was not the best with more numbers of PCR cycle, although the species number was much more. In all, when the PCR cycle number is 25, the number of species and proportion of the community composition were the most optimal both in soil or chyme samples.

Objective To analyze causative factors for and therapeutic effect of total glucosides of paeony (TGP) on palmoplantar pustulosis (PPP).Methods Ninety patients with PPP were recruited in this study.A questionnaire survey was carried out to collect clinical data from these patients,and a patch test to identify contact allergens for these patients.All the patients were randomly divided into two groups:observation group treated with TGP capsule 0.6 g thrice a day,and control group treated with tripterygium glycosides tablets 20 mg thrice a day.Both groups topically applied mometasone furoate cream once a day.The efficacy and side effects were evaluated 4 and 8 weeks after initiation of treatment.Results Of the 90 patients,the ratio of male to female was 1 ∶ 1.64,smokers amounted to 42.22％,and 23 (26.67％) reported a history of infection before the onset of PPP.As the patch test showed,potassium dichromate and nickel sulfate were the most common contact allergens in these patients.The response rate was significantly higher in the observation group than in the control group after 4 weeks of treatment (64.44％ vs.40.00％,x2 =5.388,P ＜ 0.05),but similar between the two groups after 8 weeks of treatment (88.89％ vs.80.00％,x2 =1.353,P ＞ 0.05).No significant difference was observed in the occurrence of adverse reactions between the two groups (17.78％ vs.11.11％,x2 =0.809,P ＞ 0.05).Conclusions Smoking may play a certain role in the development of PPP,and infection seems to be a primary inducing factor.TGP combined with mometasone furoate cream is effective for the treatment of PPP.
ABSTRACT
[Objectives]To probe into the nursing effects of comprehensive psychological nursing intervention for modified radical mastectomy in breast cancer patients. [Methods]160 breast cancer patients were randomly divided into Group A, control group B, experimental group(n=80). Group A was conventional y nursed as required, while to Group B, a supplement of comprehensive psychological nursing intervention was added, which concerned with pre-surgery cognition, emotion and attitude. [Results] Group B showed a notable improvement in their anxiety state after the nursing intervention, compared with Group A(P<0.05). In addition, the rate of satisfaction was far increased, and the average number of hospitalizing days was sharply decreased compared with Group A(P<0.05).[Conclusions]Comprehensive psychological nursing intervention for modified radical mastectomy in breast cancer patients can ease the pre-surgery anxiety, decrease the average number of hospitalizing days and increase the rate of hospitalizing satisfaction. It is proved to be an effective nursing intervention.
