Objective To investigate the clinical and pathological manifestation of acute kidney injury ( AKI) following infusion of clindamycin .Methods 12 patients were diagnosed as the infusion of clindamycin induced AKI .The clinical and pathological manifestations of these patients were investigated .Results 8 patients (66.7%) had episodes of gross hematuria .Oliguria and anuria was in 6 patients(50.0%).The histological diagnosis of acute interstitial nephritides(AIN) included 5 patients(83.3%).The immunofluorescent examination was negative in all cases .Renal replacement therapy were delivered to four patients .Prednisone was prescribed to 7 patients .All of patients discharged from the hospital and free of renal replacement therapy .The level of serum creatinine decreased to normal 6 months later .Conclusion Most of the AKI associated with clindamycin was oliguria with episodes of gross hematuria ,while the manifestations of skin rash were uncommon .The histological changes revealed AIN .The recent prognosis was relatively good ,but the long-term prognosis should be investigated .

Objective To explore the effect of maintenance hemodialysis(MHD)patients with secondary hyperparathyroidism on radial artery calcification and arteriovenous fistula( AVF) function.Methods The specimens of radial artery and cephalic vein were collected from the 35 cases of MHD patients at the first time of arteriovenous fistula operation.The specimens were collected again when AVF loss function more than 2 years.Specimens of the arteries were examined histologically for calcification with von Kossa staining.According to the parathyroid hormone levels,the patients were divided into three groups,as mild secondary hyperparathyroidism group (iPTH<300pg/L) of 16 cases,moderate secondary hyperparathyroidism group (iPTH≥300pg/L,<800pg/L) of 7 cases,severe secondary hyperparathyroidism group ( iPTH≥800pg/L) of 12 cases.The pathological results were analyzed.Results The pathological results showed radial artery calcification and calcium salt staining positive significantly increased in the 35 cases of MHD patients[9cases(25.7%)vs 2cases(8.6%)],compared with the first time of arteriovenous fistula operation when AVF loss function (χ2 =5.290,P=0.020).The artery calcification was also located in the layer of medial smooth muscle cells.The radial artery specimens with calcium salt staining positive increased significantly in severe hyperparathyroidism patients group[12cases(25.7%) vs 1case(6.3%)],compared with mild secondary hyperparathyroidism patients(χ2 =5.168,P =0.012).Conclusion Calcification risk of radial artery in AVF is increased in MHD patients with secondary hyperparathyroidism.And hyperparathyroidism may be one cause of AVF failure.

Hydronephrosis after spinal cord injury (SCI) may result in renal insufficiency which ranks as the most common late cause of death in SCI patients. SCI may cause vesicourethral dysfunction of nerve regulation, which in turn brings about functional obstruction, high intravesical pressure, increase of the incidence and frequency of detrusor uninhibitory constractions, leading to hydronephrosis. The paramount principle of prevention and treatment of hydronephrosis is keeping low vesical pressure (storage pressure <40 cmH2O, voiding pressure <60 cmH2O). Oral anticholinergics combined with intermittent catheterization are the best choice for the slight hydronephrosis, urinary operations such as botulinum toxin injection into detrusor, transurethral sphincterotomy, ileocystoplasty may be needed for the moderate and severe hydronephrosis.

Objective To investigate rheumatic disease manifestations in patients with myelodysplastic syndromes and explore possible causes.Methods Nine myelodysplastic syndromes(MDS)inpatients with rheumatic disease manifestations were reviewed retrospectively.Results Nine patients with the diagnosis of MDS had active rheumatic disease manifestations with various degree of hypergammaglobulinemia and positive autoantibodies.Two patients had rheumatoid arthritis(RA)and RA+anti-phospholipid syndrome(APS),four systemic lupus erythematosus(SLE)and SLE+polymyositis(PM),one patients had adult onset Still's disease, one with acute arthritis and cutaneous vassulitis,one had lupus-like manifestations including polyserositis,al- buminuria,hypocomplementemia and positive Commb's test.Conclusion The rheumatic disease manifesta- tions in patients with myelodysplastic syndromes are characterized by various active rheumatic disease manifes- tation.Immunological abnormalities and ineffective hematopoiesis are persistent.Immunologic abnormalities in MDS such as impaired function of T and B cells,hypergammaglobulinemia,positive autoantibodies,may be the causes of various rheumatic manifestations.We suggest that there is a significant association between myeludys- plastic syndrome and rheumatic diseases.

Chinese materia medica resource (CMM resource) is the foundation of the development of traditional Chinese medicine. In the study of sustainable utilization of CMM resource, adopting innovative theory and method to find new CMM resource is one of hotspots and always highlighted. Pharmacophylogeny interrogates the phylogenetic relationship of medicinal organisms (especially medicinal plants), as well as the intrinsic correlation of morphological taxonomy, molecular phylogeny, chemical constituents, and therapeutic efficacy (ethnopharmacology and pharmacological activity). This new discipline may have the power to change the way we utilize medicinal plant resources and develop plant-based drugs. Phylogenomics is the crossing of evolutionary biology and genomics, in which genome data are utilized for evolutionary reconstructions. Phylogenomics can be integrated into the flow chart of drug discovery and development, and extends the field of pharmacophylogeny at the omic level, thus the concept of pharmacophylogenomics could be redefined in the context of plant pharmaceutical resources. This contribution gives a brief discourse of knowledge pedigree of pharmacophylogeny, epistemology and paradigm shift, highlighting the theoretical and practical values of pharmacophylogenomics. Many medicinally important tribes and genera, such as Clematis, Pulsatilla, Anemone, Cimicifugeae, Nigella, Delphinieae, Adonideae, Aquilegia, Thalictrum, and Coptis, belong to Ranunculaceae family. Compared to other plant families, Ranunculaceae has the most species that are recorded in China Pharmacopoeia (CP) 2010. However, many Ranunculaceae species, e. g., those that are closely related to CP species, as well as those endemic to China, have not been investigated in depth, and their phylogenetic relationship and potential in medicinal use remain elusive. As such, it is proposed to select Ranunculaceae to exemplify the utility of pharmacophylogenomics and to elaborate the new concept empirically. It is argued that phylogenetic and evolutionary relationship of medicinally important tribes and genera within Ranunculaceae could be elucidated at the genomic, transcriptomic, and metabolomic levels, from which the intrinsic correlation between medicinal plant genotype and metabolic phenotype, and between genetic diversity and chemodivesity of closely related taxa, could be revealed. This proof-of-concept study regards pharmacophylogenomics as the updated version of pharmacophylogeny and would enrich the intension and spread the extension of pharmacophylogeny. The interdisciplinary knowledge and techniques will be integrated in the proposed study to promote development of CMM resource discipline and to boost sustainable development of Chinese medicinal plant resources.
