Objective To analyze the characteristics of blood loss for laboratory test of critically ill premature infants,and to seek feasible measures to reduce the blood loss.Methods Two hundred and forty-six cases of critically ill premature infants admitted to the neonatal intensive care unit from April 2012 to April 2013 were analyzed the blood loss for test during the hospitalization and the clinical features of blood loss with different gestational age,different weight within the first four weeks after admission.Then the application of blood loss according to test category was described.The blood volume demanded in theory was determined by the formula B =5 (∑ s + 0.1),then calculated the phlebotomy overdraw on the basis of the practical blood loss and analyzed the characteristics of overdraw per patients per day in first two weeks after admission.Results Among 246 patients,The median blood loss figure was 25.57 ml for each infants with the range between 7.10 ml ～ 119.20 ml,and the blood loss concentrated in first four weeks,which showed a decreasing trend with time.There was a statistically significant difference(P ＜0.05)that the smaller gestational age,the lower birth weight,the more daily blood loss per patient per day in first two weeks,but no significant differences(P ＞ 0.05) between the third and fourth week.The largest proportion of the blood samples was used for clinical chemical tests(31.49％),followed by blood gas analysis (19.03％),immunoassays (12.69％),blood cultures (12.63％),hematology (12.28％).The practical blood loss was about twice times of blood volume demanded for tests in theory,which the median was 7.8 times to the latter(25.57 ml vs 3.26 ml).It showed statistically significant difference(P ＜0.05) between blood overdraw per patients per day in the first week and the second week.Compared with different gestational age and birth weight,the difference of overdraw was also statistically significant(P ＜0.05).According to test category,blood culture was the most significant samples of phlebotomy overdraw,followed by biochemical,other,blood gas analysis,the percentage was 76％,64％,45％ and 41％ respectively.Conclusion The blood loss for laboratory test and the phenomenon of blood waste is serious in critically ill preterm infants.The smaller the gestational age is,the lower the weight is,the amount of blood loss and phlebotomy overdraw are more significantly.Biochemical and blood gas analysis are the main items of blood loss.

It is one of the main characters of malignant tumors that malignant tumor cells invade surrounding tissues and metastasize to distant tissues .Multiple factors are involved in this complicated dynamic process .Metastasis is the major factor influencing recurrence and prognosis .Therefore, it is important to explore the mechanism of invasion and metastasis for reducing recurrence rate and mortality of malignant tumors .Engulfment and cell mobility ( ELMO) family is one kind of conserved protein in evolutional process .It includes 3 members, ELMO1, ELMO2 and ELMO3.The members of ELMO family play an important role in cell phagocytosis and cell migration , and they also have close correlation with ma-lignant tumor cell invasion and metastasis .In this paper , we review the progress of the relationship between ELMO family and malignant tumor invasion and metastasis .

Abstract: Objective　To investigate the species distribution and the antifungal susceptibility of fungi originating from positive blood cultures in Guangdong, so as to provide a basis for the rational use of antifungal drugs in clinical fungal bloodstream infections. Methods All data were collected for retrospective study from monitoring units of the Guangdong Fungal Disease Surveillance Network between 2019-2021, including clinical characteristics, species distribution and antifungal susceptibility. Results A total of 3 589 fungi strains were isolated, most of which were Candida spp. (86.5%, 3 105/3 589). The most common species was Candida albicans (36.6%, 1 315/3 589), followed by Candida tropicalis (17.4%, 1 626/3 589) and Candida parapsilosis (14.5%, 520/3 589). There were 42.1%(1 512/3 589) of strains isolated from ICU. The proportions of Candida albicans strains were 40.0%-50.0% among ICU, general surgery, organ transplantation and emergency department. Candida tropicalis (60.0%, 144/240) was the most common species in hematology department. Both Cryptococcus neoformans (35.4%, 69/195) and Talaromyces marneffei (35.9%,70/195) were common in infection department. All of the Candida isolates were of wild-type (WT) phenotype to amphotericin B. Resistance rates of caspofungin and micafungin for Candida spp. ranged from 0.0% to 4.2%. The resistance rates of Candida tropicalis to fluconazole and voriconazole were 42.3% and 38.9%, which were significantly higher than other common Candida spp. The cryptococcus neoformans strains were totally of WT phenotype to fluconazole and voriconazole. Conclusions Candida albicans is the most common species originating from positive blood cultures in Guangdong Province. Common Candida strains are highly sensitive to echinocandins and amphotericin B. Candida tropicalis has a high resistance rate to triazole drugs.

Objective To observe the clinical efficacy of HE’s needling method (three ways for unblocking) in treating mild simple obesity due to dampness from spleen deficiency.Method Forty eligible subjects with mild simple obesity due to dampness from spleen deficiency were randomized into group A and group B, 20 cases in each group. Group A was intervened by mild unblocking method plus intensive unblocking method from HE’s needling method, and group B was by mild unblocking method plus warm unblocking method. The obesity-related indexes were observed before and after treatment, and the clinical efficacies were compared.Result The body weight and Body Mass Index (BMI) were significantly changed after intervention in the treatment group (P<0.05). The body weight was significantly changed after treatment in the control group (P<0.05). After treatment, there were no significant differences in comparing the obesity-related indexes (body weight, BMI, waist circumference, hip circumference, and waist-hip ratio) between the two groups (P>0.05). The total effective rate was 55.0% in the treatment group versus 10.0% in the control group, and the difference was statistically significant (P<0.01).Conclusion HE’s needling method is effective in treating mild simple obesity due to dampness from spleen deficiency, and mild unblocking method plus intensive unblocking method can produce a more significant efficacy compared to mild unblocking method plus warm unblocking method.

The leading cause of drug withdrawal from market and clinical trials failure is drug-induced liver injury (DILI). Varying clinical, histological and laboratory features of DILI, as well as undefined underlying mechanisms, hinder patients to be diagnosed in the early-stage of the disease and receive effective treatments. Conventional indicators, like serum transaminases and bilirubin, have inevitable limitations referring to sensitive prediction and specific detection of DILI. In order to reduce the occurrence of DILI, researchers have attempted to discover potential biomarkers with higher specificity and sensitivity from blood and urine in recent years. This article aims to review recent advances in biomarkers of DILI.

To study the name of Wenyujin Rhizoma Concisum and Film Turmeric by literature research methods provide the basis for correct application of Cuba in modern clinical application. Wenyujin Rhizoma Concisum and Film Turmeric often called each other mutual generation and used as the same kind of medicine in the ancient prescriptions books. They were often recorded and stated as the same species of Curcumae Longae Rhizoma. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma also often called each other mutual generation in the ancient prescriptions books and used as the same kind of medicine. Wenyujin Rhizoma Concisum was often recorded and stated under the Curcumae Longae Rhizoma articles in the ancient materia medica literatures. Ancient literatures on Wenyujin Rhizoma Concisum records were almost the same, the modern literatures on the records of the sources of Wenyujin Rhizoma Concisum were inconsistency. Inconsistency of Wenyujin Rhizoma Concisum source records in modern literatures was related to the changes of the modern records on source records about Curcumae Longae Rhizoma, Root-tuber of Aromatic Curcumae Longae Rhizoma and Zedoray. The author thinks that Wenyujin Rhizoma Concisum is the ancient Film Turmeric which referes to the same medicine as Curcumae Longae Rhizoma. The source of it just as the Curcumae Longae Rhizoma is not only one kind. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma have been recorded as two medicines at the present, and the source of them simply referes to the original plant Curcuma wenyujin. When using ancient prescriptions, we need to understand the changes that Curcumae Longae Rhizoma and Wenyujin Rhizoma Concisum are the same in ancient but different today in order to choose medicine correctly in the clinical.
