The single ventricular circulation is notable for coexisting systemic venous hypertension and pulmonary arterial hypotension. The use of mechanical circulatory support (MCS) devices is a viable therapeutic treatment option for patients with congestive heart failure. Ventricular assisted devices, cavopulmonary assisted devices, and total artificial heart pumps continue to gain acceptance as viable treatment strategies for single ventricular physiology patients as bridge-to transplantation, bridge-to-recovery, and longer-term circulatory support alternatives. Patients with single ventricular physiology had the lower survival rates compared with those with biventricular circulation. We present a review of the current and future MCS devices for patients with univentricular circulations.
ObjectiveTo investigate therapeutic effect and influence on survival of complete laparoscopic transesophageal hiatus approach approach and transabdominal combined thoracotomy approach in treatment of Siewert type Ⅱesophageal gastric junction adenocarcinoma (AEG).MethodsFrom January 2012 to December 2014, the patients with Siewert type Ⅱ AEG were collected in the Department of General Surgery (Gastrointestinal Surgery) of Weifang People’s Hospital, then who were designed into a transabdominal group and transabdominal combined thoracotomy group according to the operative approach method. The intraoperative and postoperative statuses were compared between these two groups.ResultsIn this study, 142 patients with Siewert type Ⅱ AEG were included, 83 in the transabdominal group and 59 in the transabdominal combined thoracotomy group. There were no significant differences in the baseline data such as the gender, age, preoperative histological differentiation, TNM stage, etc. between the two groups (P>0.05). Compared with the transabdominal combined thoracotomy group, in terms of the operation time, the volumes of intraoperative blood loss and blood transfusion, and the proportion of patients with blood transfusion were better (P<0.05); the postoperative hospitalization time, time to use analgesics, time of the first activity out of bed, and time of removed electrocardiographic monitoring were also earlier (P<0.05); the numbers of lymphadenectomy and metastatic lymph nodes were less (P<0.05) in the transabdominal group. But there was no significant difference in the rate of lymph node metastasis between the two groups (P>0.05). The total incidence of complications in the transabdominal group was lower than that in the transabdominal combined thoracotomy group (χ2=9.871, P=0.002). The median survival time was 39 months in the transabdominal group and 34 months in the transabdominal combined thoracotomy group. The survival had no significant difference between the two groups by the Kaplan-Meier analysis (χ2=0.281, P=0.596). The result of multivariate analysis showed that the TNM stage and lymph node positive rate were the independent factors influencing the survival of the patients with Siewert type Ⅱ AEG.ConclusionsAccording to results of this study, it is safe and effective for patients with Siewert type Ⅱ AEG to adopt a complete laparoscopic transabdominal approach. For elderly patients with poor cardiopulmonary function who can not tolerate transthoracic surgery, it could reduce postoperative complications and improve safety.

Results A total of 113 drugs in 19 categories were appl ied to 7 children with crush syndrome. Most children used Vitamins and antibacterial agents. The cost of gamma globul in injection was the highest. Conclusions The rational ity valuation for children medication lacks international vulgate index and needs more basic research.
Objective To investigate the relationship of cluster of differentiation 40L (CD40L) between inflammatory response mediated by vascular endothelial injury and Stanford A type aortic dissection (STAAD). Methods In this study from August 2016 to February 2017, a total of 215 blood samples from 95 STAAD patients (67 males and 28 females aged 48.33±12.19 years) and 120 healthy volunteers (94 males and 26 females aged 48.64±10.13 years) were collected. The patients with aortic dissection were taken blood 1 hour before the operation and the healthy volunteers were taken blood from the elbow vein. All STAAD patients were diagnozed by computed tomography angiography (CTA) and patients with Marfan syndrome were excluded. Blood samples were tested by enzyme-linked immunosorbent assay (ELISA) for CD40L, vascular cell adhesion molecule (VCAM-1), E-selectin, interleukin-1 (IL-1) beta, IL-6, tumor necrosis factor-alpha (TNF-α) and so on. ResultsCompared with the healthy population, the level of SCD40L(26.87±5.50 ng/ml vs. 13.39±4.03 ng/ml, P<0.001) in the STAAD patients was significantly higher. E-Selectin (116.62±25.24 ng/ml vs. 77.05±14.30 ng/ml, P<0.001), VCAM-1 (P<0.001), TNF-α (55.35±9.12 ng/ml vs. 37.33±5.61 pg/ml, P<0.001), IL-1β (62.12±13.37 ng/ml vs. 48.68±9.86 pg/ml, P<0.001), IL-6 (499.54±90.45 ng/ml vs. 422.44±34.00 pg/ml, P<0.001) significantly increased. Conclusion The increased expression of SCD40L in STAAD patients and the inflammatory reaction induced by endothelial injury in aortic dissection patients are obvious.
Objective To investigate and analyze the status of clinical guidelines of children in China, so as to regulate the development of children’s evidence-based clinical guidelines and provide recommendations for children’s clinical guidelines. Methods Names of guidelines, year and institution of publication, methodology of development and reference number were descriptively analyzed. Years of publication and diseases of guidelines were analyzed with statistical graphs. AGREE instrument was used to evaluate the evidence-based guidelines of children. Results a) Of 91 clinical guidelines of children, 62 were translations. Of 29 guidelines ourselves, nine were traditional Chinese medicine guidelines and five (17%) were evidence-based guidelines; b) Guideline on Rational Use of Antibiotics in Acute Respiratory Infections (Probation), the first guideline of children, was published in 1999. Guidelines of children was not published until 2005. Then, the number of guidelines was increasing each year and reached a peak in 2008. Of 13 guidelines in 2008, seven were traditional Chinese medicine guidelines. Guidelines on respiratory diseases were 14 ranked as the top; c) Guidelines on congenital deformity and chromosomal abnormalities, tumor, circulatory system disease, blood disease and western guideline on communicable disease were not formulated in China; and d) Average scores on six domain of five evidence-based guidelines were 84.4%, 37.5%, 74.3%, 90.0%, 22.2%, 46.6%, respectively. Guide on Diagnosis and Treatment of Children Aged 0 to 5 with Acute Fever of Unknown Etiology was bly recommended, Guide on Management of Children with Community-Acquired Pneumonia, Evidence-Based Guide on Diagnosis and Treatment of Children with Common Kidney Disease, Guide on Nutrition Support of Newborn, Guide on Diagnosis and Treatment of Children with Chronic Cough were recommended. Conclusion Clinical guidelines of children in China begin late, develop slowly and are lack of update. A standard on development of guidelines is needed. The government should increase the fund of development, implementation and promotion of guidelines. Recommendations for high-quality guidelines should be included in procedure of medical quality assurance. Compliance of guidelines should be provided by organization which formulatesd the guideline, so as to promote the application of high-quality guidelines.
Objective To study medication usage in women and children from the distress area related to the Wenchuanearthquake. Methods Information about which medications that 329 patients used in West China Second University Hospital,Sichuan University was collected by the HIS system and classified by using the ICD-10system.The cases and times of medication, the total number of drugs, the drug cost per capita, and the drug cost per day were calculated using Excel. The defined daily dose (DDD) and drug utilization index (DUI) were analyzed. According to the principle of DDD amp; DUI, CDDD amp; CDUI were designed to analyze the drugs used by children. Results A total of 398 drugs in 25 categories were applied to 329 patients. Every case used infusion solutions, the DDDs of vitamins were the highest, the usage and duration of vitamins and antibacterial agents were the longest among the 25 kinds of the drugs. The cost of Amoxicillin Sulbactam injection was the highest. Many kinds of medications were prescribed to these patients,the rate of DUIgt;1 vs DUIlt;1 are 32.3% amp;47.2%. The results of CDUI indicated overuse of drugs was serious in children less 1yr old.The CDUI of precortisyl was the highest:40 to 80. Conclusions The system for distribution of medication to patients to children and women during an emergency is flawed. According to our findings we make new suggestions for changes, which have to be proved by further research.

ObjectiveTo systematically review the classification system for the causes of pediatric drug shortages in China, and classify the causes of pediatric drug shortages accurately, so as to provide references for the formulation of targeted strategies. MethodsFour databases including Embase, PubMed, CBM and CNKI were searched from inception to November 2023. Quantitative research, qualitative research and mixed-method research on the causes of pediatric drug shortages in China were included. Two researchers independently screened the literature and extracted data. Based on the theory of efficient market and effective government, and according to the life cycle of the drug supply chain, the fundamental causes of drug shortages were classified and summarized by thematic synthesis. ResultsFourteen articles were included. According to the four stages of the drug supply chain (research and development, production, circulation and use), a total of 19 categories of causes of the pediatric drug shortages were summarized, including 5 categories in the research and development stage, 4 categories in the production stage, 6 categories in the circulation stage, and 4 categories in the use stage. Based on the theory of efficient market and effective government, further analysis of the causes revealed that the identified reasons could be attributed to three major fundamental causes: market failure, government failure, and other causes. Among them, 6 categories were related to market failure, 7 categories were related to government failure, and 6 categories were classified as other causes. ConclusionBased on the theory of efficient market and effective government, this study established a classification system of fundamental causes of the pediatric drug shortages, and made policy suggestions accordingly. Subsequently, the classification system established in this study can be used as references to develop targeted strategies to solve the problem of pediatric drug shortages in the life cycle of drug supply chain from government and market perspectives.
