ABSTRACT
Lung cancer is the most common and fatal tumor in the world with limited diagnostic and treatment methods. The development of precision medicine has brought new opportunities for the improvement of diagnosis and treatment of lung cancer. However, various kinds of information required by precision medicine (such as biometrics, clinical test indicators and non-biological environmental background information) are difficult for clinicians to integrate and utilize effectively. With the development of computer technology, artificial neural networks (ANNs), which has the characteristic of high fault tolerance, intelligence and self-learning ability. Its powerful information integration ability can solve many problems in the development and application of precision medicine, which can play a key role in basic research and clinical practice associated with lung cancer. This article reviewed the application of artificial neural network in the field of lung cancer. .

Anoectochilus, the fresh or dry whole grass of Anoectochilus roxburghii (Wall.) Lindl., has the effects of cooling blood, dispelling wind, dispelling dampness and resolving toxin, resulting in a wide range of clinical applications and large market demand. However, in the planting process, there are problems such as irregular planting management, excessive addition of pesticides, irregular processing links, even the phenomenon of selling adulteration, which seriously affects the quality of the medicine. In order to guarantee the quality and productivity of Chinese herbal medicines, this paper developed the standard operating procedures for the non-pollution Anoectochilus, including the non-pollution cultivation environment of Anoectochilus, planting methods, field management, pest control and quality control, etc., which provides guidance to promote the healthy development of the Anoectochilus industry.
ABSTRACT
Objective To investigate the predictive value of acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) for nursing workload in emergency intensive care unit (EICU).Methods A retrospective cohort study was conducted. Critical patients except for trauma admitted to EICU of West China Hospital of Sichuan University from June 2012 to July 2016 were enrolled. APACHE Ⅱ score and therapeutic intervention scoring system (TISS-28) score were calculated in each case. The relationship between APACHE Ⅱ score and TISS-28 score was analyzed by correlation analysis and curve estimation.Results A total of 1148 patients were enrolled, including 689 male (60.0%), and age of (56±19) years old, APACHE Ⅱ score was 19 (13, 25), and TISS score was 19 (13, 25). The Spearman correlation coefficient between APACHE Ⅱ score and TISS-28 score was 0.849 (P < 0.001), and that among the linear model quadratic model, composite model, growth model, logarithm model, cubic model and exponential modelR2 were 0.669, 0.710, 0.792, 0.764, 0.765, 0.765, respectively (allP < 0.01), and the most suitable description for relationship between APACHE Ⅱ score and TISS-28 score curve was cubic model. The nursing workload was significantly increased when APACHE Ⅱ score ≥30, and it was decreased when APACHE Ⅱ score < 30.Conclusion APACHE Ⅱ was a useful score for predicting the nursing workload in EICU.
ABSTRACT
Objective Preoperative preparation of blood is common.The preoperative blood ordering and transfusion practices for elective obstetric surgery were evaluated in our Renji hospital in order to develop a reasonable preoperative blood preparation schedule for those procedures where a cross-match appears necessary.Methods We evaluated blood ordering practices in total 16 232 elective obstetric surgeries in our hospital from January 1,2013 to June 30,2017 retrospectively.The age of patients,preoperative diagnosis,surgical procedures type,preparation volume of blood,intra-operative transfusion volume of blood,and excessive usage ratio of blood were calculated and analyzed.Results 455 patients transfused intraoperatively total 1 610 U red blood cells.The usage ratio of blood was 2.80％ for patients and 4.87％ for blood preparation volumes respectively.Placenta previa,ectopic pregnancy,twin pregnancy accounted for the first three of the possibility of intraoperative blood transfusion in obstetric surgeries.Conclusion The relationship between preoperative diagnosis and the risk of blood transfusion in obstetric surgery should be take attention to.Preoperative blood typing,antibody screening and appropriate cross-matching could ensure the safety of obstetric surgery.
ABSTRACT
ObjectiveTo observe the effect of Chinese medication and acupuncture-moxibustion plus Western medication on the pregnancy rate after in-vitro-fertilization and embryo transfer (IVF-ET) in different age groups.MethodTotally 810 eligible patients enrolled between 1st January 2010 and 31st December 2013 from the Reproduction and Infertility Department were categorized into 3 groups according to the age, respectively 20-29 years old, 30-39 years old, and 40-49 years old. The pregnancy rates of the three groups were compared, and the pregnancy rate of IVF-ET after the treatment of the integrated treatment of Chinese and Western medicine was also statistically analyzed.ResultThe pregnancy rate was 54.3% in the group of 20-29 years old, versus 46.4% in the group of 30-39 years old and 26.0% in the group of 40-49 years old, and the total pregnancy rate of IVF-ET was 47.2%. ConclusionThe younger, the higher the pregnancy rate of IVF-ET, and intervention of traditional Chinese medicine following the assisted reproductive technique can enhance the pregnancy rate of IVF-ET.
ABSTRACT
Objective] To explore the relationship between excessive internal heat in TCM and intestinal microflora ,provide scientific evidences for pathogenesis of excessive internal heat.[Method]With the research methods of clinical observation and literature review,analyze the characteristics of excessive internal heat,and collect research progress about intestinal microflora to find out the link.[Result] Head and facial tissue is more susceptible to injury,which is determined by the organizational characteristics. People suffering from excessive internal heat widely have problems of energy metabolism and mucosal immune disorders. Intestinal microflora plays an important role in energy production,conversion,storage and use.They can change the way that organizations use energy,and change AMPK phosphorylation to influence the energy metabolism of the body.Thus gut microflora imbalance may lead to disorders of energy metabolism.On the other hand,inflammatory mediators express abnormally in these people. Impaired immune function leads to inflammatory states,which causes imbalance of gut microflora.While intestinal microflora also can regulate intestinal mucosal immune response by adjusting related effective factors. [Conclusion]Excessive internal heat is closely related with intestinal microflora from the aspects of energy metabolism and mucosal immunity,which may provide new ideas to explore the pathogenesis of this disease.The researches based on intestinal microflora and diseases bring brilliant prospects of individual prevention and treatment for TCM and western medicine .
