The canine saphaneous skin flap was used as a model in this experiment. The cutaneous autograft would give long-term survival, whereas the allograft without pretreatment would only survive 10. 2±1.9 days from its transplantation. If the pretreatment consisted of the use of immunosuppressive agent as PHA or infusion of dexamesone, the survival days of the allografts could be prolonged to 15.1±2.5 and 13.7±2.8, respectively(Plt;0.01). The histological examination gave the evidence that drug perfusion delayed the rejection.

Objective To evaluate the utility of collagen-gel droplet embedded-culture drug sensitivity test (CD-DST) in pancreatic carcinoma cell by compared with WST-8. Methods The chemosensitivity to 5-fluorouracil (5-FU), gemzar (GEM) and oxaliplatin (OXA) of pancreatic adenocarcinoma cells SW1990, PCT-3 and ASPC-1 were tested by WST-8 and CD-DST respectively. Results In a certain living cell number range (500-10 000), there was a linear correlation (r=0.991 1, P＜0.05) between the integral optical density in CD-DST and the cell number. The inhibition ratios of three kinds of cell growth tested by CD-DST were higher than those tested by WST-8 (P＜0.05). The results of drug chemosensitivity to 5-FU， GEM and OXA detected by two methods were uniform. Conclusion The CD-DST can be used to assay the drug chemosensitivity in vitro for pancreatic carcinoma.
Cryptococcosis, mainly caused by Cryptococcus neoformans/gattii species complexes, is a lethal infection in both immunosuppressive and immunocompetent populations. With the upgrade of detection methods and the increase of clinical knowledge, the incidence rate of cryptococcosis is increasing, and it has become one of the most important fungi threatening human health. In recent years, great progress has been made in this field, including the taxonomy and nomenclature of Cryptococcus spp., laboratory diagnostic methods and antifungal susceptibility tests, as well as the characteristics and treatments of cryptococcosis. This article reviews the above contents, in order to improve the clinical and laboratory understanding of the Cryptococcus spp., and realize the timely diagnosis and early treatment of cryptococcosis.
ObjectiveTo investigate the distribution and drug resistance of the pathogens isolated from hospitalized pediatric patients with respiratory tract infections, and to provide guidance for empiric therapy.
MethodsRespiratory tract specimens from hospitalized pediatric patients with respiratory tract infections from 2011 to 2015 were collected, and the strains were identified and the drug susceptibility was tested.
ResultsA total of 1995 strains of pathogens, 1281 (64.21%) from boys and 714 (35.79%) from girls, were isolated from 6236 specimens and the detection rate was 31.99%. The mean age of the hospitalized pediatric patients was (1.22±2.05) years (ranged from 1 day to 14 years). 1393 (69.82%) pediatric patients were younger than 1 year. Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Candida albicans and Acinetobacter baumannii ranked the top five species, accounting for 29.82%, 15.09%, 13.18%, 12.73% and 5.91%, respectively. 1995 strains included gram-negative bacteria (50.93%), gram-positive bacteria (35.29%), and fungi (13.78%). The resistance rate of Staphylococcus aureus to oxacillin was 31.76%, but it was 100% sensitive to vancomycin and linezolid. The resistant rate of gram-negative bacteria to imipenem was ranged from 1.52% to 5.93%. The resistant rate of gram-negative bacteria to ceftazidime, cefepime, piperacillin tazobactam and tobramycin was less than 30.00%.
ConclusionsThe infants whose age are younger than 1 year comprise the majority of the hospitalized pediatric patients with respiratory tract infections. The proportion of male is more than that of female. Staphylococcus aureus and enterobacteriaceae were the main isolated pathogens. There is difference in drug resistance between different pathogens, so antibiotics should be chosen according to the results of drug sensitivity testing.
Objective：To observe the therapeutic ef fect of chemoreduction treatm ent combined with local focal therapy for advanced intraocular retinoblastoma (R B).
Methods：Thirteen eyes of nine patients with RB underwent c hemoreduction tr eatment combined with local cryotherapy and (or) transpupillary thermotherapy (TTT), and the clinical data of the patients were retrospectively analyzed. The vi ncristine, etoposide, and carboplatin (VEC) were used in the chemoreduction trea tment. The average followup duration was 15.3 months.
Results：All of the 13 e yes with RB had favorable initial reaction in the treatment of chemoreduction. A fter the first period of chemotherapy, the largest diameter of the tumor fundus decreased 37.2%, and the tumor thickness averagely reduced 46.7%. The subretinal fluid was absorbed completely or partially in 6 eyes (6/8); vitreous and subret inal seeds reduced, disappeared or calcified in 10 (10/11) and 11 eyes (11/11), respectively. During the treatment and in the followup duration, 8 eyes (8/13) had new tumors and (or) recurrences. Finally, 2 eyes (2/13) were enucleated whil e 11 eyes (11/13) were saved in which 8 (8/11) recovered or remained good visual acuity. None of 9 patients had serious side effects of chemotherapy like leucoc ythemia, functional damage of liver and kidney, and dysacousia.
Conclus ions：Chem oreduction treatment has well initial effect on advanced RB. Chemoreduction trea tment combined with local treatment may effectively control the retinal tumor, s ubretinal seeds and vitreous seeds within a shortterm duration. The evaluation of longterm effect of the treatment needs further observation.
ObjectiveThis study aims to compare different references for the fetal risk of drugs used in pregnancy to provide evidence for the safety of drug use in pregnancy.MethodsFour drug databases, including Lexicomp, Micromedex, TERIS, and Reprotox, as well as two books of drugs in pregnancy edited by Briggs and Schaefer, were searched. Descriptive analysis was performed regarding the definition of pregnancy recommendations and the specific content of medication.ResultsThe six references employed slightly different approaches to drugs in pregnancy, however, all of them included summaries of the risk in pregnancy, data of crossing the placenta, and human and animal data. The databases of Micromedex, TERIS, and a book edited by Briggs had their risk classification systems for drug use during pregnancy. For specific drugs, the summary of different information in pregnancy was different, the amount and content of listed evidence varied, and there was no evaluation of the quality and relevance of evidence among the references.ConclusionsThere is no consensus on the risk assessment of drugs in pregnancy. Risk classification systems for drugs in pregnancy are still an important method for determining the fetal risk of drugs. The existing references merely list studies of drugs in pregnancy, without comprehensive quality assessment. A methodological study of assessment of the risk of drugs in pregnancy is required.
OBJECTIVE To investigate the effect of the endoexpander pressure of continuous and constant pressure expansion on the drug permeability. METHODS The expanders were divided into two groups, the normal expansion and the continuous and constant pressure expansion (4.6 kPa). Each expander was filled with 0.2% Metronidazole, then the expanders were immersed wholly in normal saline and sealed totally. At several intervals over 72 hours, the surrounding saline was sampled and the drug concentration of the sample was measured respectively. RESULTS Both groups were permeable to the Metronidazole and the concentration outside the expander would reach the effective concentration in 48 hours. The drug concentration of the continuous and constant pressure expansion was higher than that of the normal one and there was significant difference between the two groups (P lt; 0.01). CONCLUSIO The endoexpander pressure in continuous and constant pressure expansion can enhance the drug permeability. In view of this, in the course of continuous and constant pressure expansion, 0.2% Metronidazole can be used to prevent and control the infection.
Epilepsy is one of the most common neurological diseases in children, about 2/3 can be seizure-free after anti-seizure medications (ASMs) treatment, but there are still some drug-resistant epilepsy (DRE) need surgical treatment, epilepsy surgery including excision surgery, dissociation surgery and palliative surgery, surgery can make 30%~40% DRE fully controlled. Clinicians usually choose to discontinue ASMs after seizure-free for 1 to 2 years after epilepsy surgery, but there has been controversy about whether to discontinue ASMs after surgery in children with epilepsy, how long to discontinue ASMs, the timing of ASMs withdrawal, and there is still a lack of unified guidelines. This article will comprehensively analyze and summarize the risk of recurrence after ASMs withdrawal in children with epilepsy.
