With dramatic decline of genome sequencing cost,high-throughput sequencing technologies have been applied in clinical laboratory field,and play an increasingly important role in clinical diagnosis and treatment in complex diseases.Based on omics techniques,clinical laboratory data recording patient's diagnosis information has become the important independent medical research resources of the major health industry.Because these data include the patient's identity information,there are a series of ethical issues to be solved,such as protection of patients' informed consent right,patient privacy protection,information security protection,when carrying out the medical health big data research.Based on these problems,it proposed clinical laboratory data should be standard extraction,establishment of clinical laboratory data base for teaching,training,in order to improve the utilization of medical resources.Moreover,it is best to implement the written informed consent during the process of sample collection,informing the patient the data collected in diagnosis and treatment process may be used in related research in future.

Objective To explore the strategy of repairing penile defect after necrosis caused by shortwave diathermy.Methods Between January 2004 and June 2012,18 cases with penile defect after necrosis caused by shortwave diathermy were admitted in our hospital.The age of those patients ranged from 18 to 55 years old (mean 34 years old).Among them,15 cases have been married.All patients have the history of penile shortwave diathermy therapy after surgery.After debridement,penile complete defect was found in 6 cases,incomplete defect was found in 10 cases and corpus cavernosum and corpus spongiosum partly defect was found in 2 cases.Under general anesthesia,we applied penis extent in 10 cases with incomplete defect,forearm free flap in 2 cases with penile complete defect,abdominal artery perforators flap in other 4 cases with penile complete defect.In 2 cases with corpus cavernosum and corpus spongiosum partly defect,the scrotal septal skin flap and fascia pedicle flap was used for 1-stage urethral reconstruction and costicartilage was implanted for 2-stage cavernosum reconstruction.Results 18 patients were followed up for 0.5-10.0 years (mean 2.3 years).16 cases with penile complete defect or incomplete defect had normal length after operation,ranged from 6.3 to 9.2cm.During erectile phase,the length of their penis ranged from 8.7 to 11.5 cm.No feeling abnormality or erectile dysfunction was complained.All patients exhibited the excellent morphology and felling of penis with minor scar in donor site.Early (half a month) complications included distant flap necrosis in 1 case and disruption of the wound in 1 case,which were cured after debridement and conventional treatment.After one year,we did not see the flap atrophy.One case had tumid which influenced penile beautiful and sexual intercourse.It was improved by local liposuction.One month after surgery,two patients with corpora cavernosa and corpus spongiosum partial defect had normal voiding.No feeling and erectile dysfunction were complained during the following-up.Conclusions According to the characteristics of the penile defect due to the shortwave diathermy,selecting the optimal skin flap and individual repair strategy are the keys to successful treatment.

Objective To study the effects of prenatal cocaine exposure on the development of offspring's brains by building a murine model. Methods We weighted the body weight and brain weight of offspring on P10 from COC and SAL groups and observed the development of neuron and astrocyte in cerebral cortex by toluidine blue staining and immunohistochemistry. Results The brain weight and body weight from COC were both reduced on P10 compared with SAL group.We discovered prenatal cocaine exposure induced polarity disorder and dysplasia of neuron in cerebral cortex;the number of the astrocytes in corpus callosum and hippocampus regions decreased.Conclusion\ Pregnatal cocaine exposure can result in abnormal development of cerebral cortex of offsprings which may play an important role on cocaine induced abnormal behavior.\;[

Objective To conduct comparative study of vertebral artery blood flow of arteriosclerosis patients and healthy people using color Doppler ultrasound (CDUS),and to discuss the effect of arteriosclerosis on vertebral arterial blood flow.Methods Two hundred and eighty-five cases of vertebral artery test were collected and divided in to normal group of one hundred and thirty-five cases and vertebral artery sclerosis group of one hundred and fifty cases according to the presence of vertebral artery sclerosis.Time averaged maximum velocity (TAMV) and vertebral artery diameter(D) of vertebral artery were measured using CDUS technique.Unilateral vertebral artery blood flow and total blood flow were calculated.Results The vertebral artery TAMV and total blood flow of arteriosclerosis group was both lower than that of normal group (P<0.05).Left side vertebral artery diameters of the two groups were higher than that of the right side.Conclusions Arteriosclerosis can reduce vertebral artery TAMV and blood flow.The inner diameter of the left side vertebral artery dominates the artery blood flow.

AIM To develop a murine model for investigating the effects of prenatal cocaine exposure on the development of fetal nerve system. METHODS A nutritionally paired control group of dams injected with saline and pair fed with the COC dams were set up. Another two groups were COC groups injected with cocaine HCl and SAL group administrated with saline. After injection twice daily during gestation days 8~17,mice were decapitated on E17 and blood and brain samples were collected for pharmacological analysis and neurotransmitter analysis by HPLC.RESULTS Pharmacological analysis revealed that cocaine was found in maternal and fetal plasma at 15 min following ip administration to embryonic day E17 pregnant mice. Though COC dams and SPF dams had the same feeding condition, compared with the latter, the former had higher maternal concentrations of DA and 5 HT, lower fetal weight, brain weight, striatum weight and higher concentrations of DA and 5 HT in striatum, P

AIM To investigate the effects of in utero cocaine exposure on the fetal development, when fetuses were exposed to equal total dose but different dose and timing. METHODS Pregnant dams were randomly separated into three groups: SAL, COC20 and COC40. On E17, recorded body weight, brain weight and striatum weight of all groups, and examined the concentrations of DA and 5 HT in fetal striatum by HPLC. RESULTS Body weight of SAL, COC40, COC20 groups decreased progressively in turns. Brain weight of COC20 group and COC40 group was lower than that of SAL. Only the brain/body ratio of COC40 was decreased ( P
