Following with the naissance and the development of the DICOM(the Digital Image Communication in Medicine) protocol,and numerous medical image equipments factory's support to the DICOM protocol,PACS(picture archiving and communication systems)are popularized quickly in hospital image section room,which pushes the progress of PACS industry.Hospitals have always been certain blindness in ushering and arguing PACS systems,uncertain how to control those providing company exactly on the technique.In this paper,some key problems are introduced in order to make everyone understand the relevant technique.

Objective To reinforce the training and management of residents in gynecology and obstetrics so as to enhance their general medical proficiency. Methods In view of the major weaknesses of the residents, specifics for training and assessment were worked out so that quantified assessment could be conducted. Results After a years work, there was a significant increase in the rate of first class medical records and the number of research papers published. There was also an improvement with regard to the safety of medical procedures. But there was no marked improvement in the performance of ward rounds assessed or the rate of excellent operations. Conclusion Quantified assessment, a relatively objective and impartial method, has spurred the residents to enhance their general medical proficiency.

Objective To investigate the application value of urine excrement shunt surgery for the treatment of severe metabolic disorders after Sigma rectum pouch of bladder cancer.Methods From July 2011 to December 2013,4 male patients (mean age 72±10 years old,ranged from 58-82 years old),who received radical cystectomy and Sigma rectum pouch due to bladder cancer,were admitted in our hospital.Within four years after the operation,all patients complained about the recurrent fatigue,anorexia and even unconsciousness.The hyperchloremic metabolic acidosis,hypokalemia and renal dysfunction were diagnosed by blood gas analysis and biochemical tests.One week before urine excrement shunt operation,the arterial blood pH,HCO3-,serum potassium,chloride and creatinine were (7.15±0.08),(7.8±4.7)mmol/L,(3.1 ±0.2) mmol/L,(110.3±4.7) mmol/L,(314.8±66.4) μmol/L,respectively.They received urine excrement shunt surgery.The lower abdominal mid-line incision was made and the pouch was isolated from intestinal tract.The abdomen ostomy was made and the sigmoid colon and rectum were re-coincided in order to recover the intestinal continuity.The results of blood gas analysis,electrolytes and renal function after surgery were compared with those before surgery.Results The average operation time was (256.3±26.9) min and the mean volume of bleeding was (147.5±111.2) ml.There was no surgery related complication.Blood bicarbonate was (19.1±4.8) mmol/L one week after surgery,which was significantly improved than that before operation (P＜0.05).One month later,blood pH level descended to (7.38±0.05),potassium level was (3.9±0.3) mmol/L,creatinine was (208.8±50.8) umol/L.All of them were significantly improved,compared with those results before surgery (P＜0.05).Blood chloride was significantly reduced to (102.4±5.8) mmol/L (P＜0.05) after 6 months of operation.Nobody developed severe acidosis and electrolyte disturbances during 6 months to 3 years' follow-up.Conclusions Urine excrement shunt surgery can effectively corrected the acidosis and electrolyte disturbances due to the radical cystectomy and Sigma rectum pouch.It might be a alternative method to treat such kind of severe complications.

OBJECTIVETo report a case of simple congenital bilateral ejaculatory duct absence (EDA) complicated with seminal vesicle cyst and review the relevant literature in order to improve the diagnosis and treatment of the disease.

METHODSWe retrospectively reviewed the clinical data of a case of bilateral congenital EDA complicated with seminal vesicle cyst, reviewed the relevant literature at home and abroad, and comprehensively analyzed the embryonic development, diagnosis, and treatment of congenital EDA.

RESULTSThe patient was a 23-year-old man, present at the clinic for infertility after married for a year. Vasography and other imaging examinations confirmed simple congenital bilateral EDA complicated with seminal vesicle cyst. Pathologic biopsy showed normal spermatogenic function of the testes.

CONCLUSIONCongenital EDA originates from embryonic developmental defect of the mesonephric duct, and it can be confirmed by vasography. Transurethral incision of the ejaculatory duct and intracytoplasmic sperm injection can be employed for the treatment of bilateral EDA.

Xenograft mice are preclinical animal models of tumors and are widely utilized in anti-tumor research. PK/PD modeling of anti-tumor agents is an approach that can capture the time profile of the "dose-plasma concentration-biomarker level-tumor volume" process based on experimental data from xenograft mice using a non-linear mixed-effect model. PK/PD modeling can help optimize the dosing regimen for anti-tumor therapy, evaluate any synergistic effect and help identify an optimal schedule for combination therapy, as well as providing a preliminary estimate of a drug's efficacy and anti-tumor potency in the human body. PK/PD modeling can also help by quantitatively explaining the mechanism of the tumor-inhibitory effect as indicated by changes in biomarker levels after a drug acts on its target. This article provides a systematic summary of the background, application range, and limitations of the mainstream anti-tumor agent PK/PD models. Recent advances in model structure development are reviewed in detail. Finally, we discuss promising applications of PK/PD models in anti-tumor medicine development from the perspective of a drug's mechanism of action, optimization of combination therapy schedules, and their clinical translation.
