Nowadays,more and more male doctors major in Obstetrics and Gynecology.Due to traditional Chinese ideas and conception,females don′t like to be treated by male doctors.This thesis article discusses the features of patients in Obstetrics and Gynecology,the situation which male doctors face,aiming to find out appropriate cultivating ways for male doctors to improve their ethical and moral accomplishment,so as to better adapt male doctors to clinical practice and work improve the relationship between male doctor and female patients.

Based on domestic and international studies on Career-Life-Cycle theories,this paper analyzed the scientific research data of doctors to elucidate characters of varied steps in clinical and research practices,trying to construct Research Life-Cycle theory for doctors and provide theoretical references of talent cultivation in hospitals.

Objective To explore the mental education and continuing education among non-psychiatric medical workers of the general hospitals in Guangzhou city.Methods A cross-sectional study was carried out in 17 general hospitals of Guangzhou city including 2617 participants from December 2012 to April 2013.Results Among 2617 participants,41.6％ of them hadn't taken part in psychiatric course study,66.9％ hadn't received psychiatric rotation,and 66.7％ hadn't received psychiatry and related training;93.8％ of the medical staff had interest in mental specialized training courses,of which 72.0％ medical staff stood for training classes/participation,72.3％ medical staff most satisfied with 4-5 days of a training course,strengthen training every 6 months (2 days) and a psychiatrist to connect.Conclusion Non-psychiatric medical workers of the general hospitals in Guangzhou city lack the knowledge of mental health,and mental health care training are urgently needed.

ObjectiveTo investigate the incidence and risk factors in retinopathy of prematurity (ROP) at matched gestational age.Methods Data collected by the medical records of neonates from November 2007 to December 2010 in our neonatal database were analyzed.Patients'information was recorded from birth to discharge from NICU.Data included age after birth (hours),gestational age,body weight at birth,treatment,and maternal demographics.The statistical study was carried out by SPSS version 13.0 software.Mann - Whitney U test was used for numerate data.Fisher's exact probability test and Pearson's chi - square test were used to compare quantitative variables between independent groups.P values were considered significant when they were less than 0.05 ( two - sided).ResultsThe incidence of ROP was 5.38％.Gestational age of ROP group and control group was matched ( P =0.387 ),but difference in body weight at birth was significant ( P =0.045 ).Age after birth was significantly different ( P =0.013 ).Apnea and anemia were significantly different between two groups (P ＜ 0.01). The differences in duration of hospitalization,NCPAP and use of antibiotics between two groups were significant ( P ＜ 0.002,0.000 and 0.000,respectively).ROP group differed from control group greatly in hospitalization expenses.Multiple stepwise logistic regression analysis showed that oxygen supplenentation ( P =0.0237 ) and infection ( P =0.0118) were risk factors of ROP. ConclusionsThe incidence of ROP in NICU in Beijing Children's Hospital was 5.38％.Inhalation of oxygen supplementation and infection were risk factors of ROP.

Objective·To investigate the correlation of single nucleotide polymorphism (SNP) of complement factor H (CFH) gene with schizophrenia in Chinese Han population.Methods·The genotype,allele,and haplotype frequencies of 5 SNP loci (rs800292,rs 1061170,rs 10801555,rs 10922096 and rs2019727) in CFH gene were compared between 418 patients with schizophrenia (case group) and 655 normal people (control group) by SNaPshot technique.Results·All SNP loci were well genotyped in the subjects.Correlation analysis showed that rs1061170 locus allele frequency distribution difference between case group and control group was statistically significant (corrected P=0.045),while genotype and allele frequencies of other SNP loci were not significantly different (all corrected P＞0.05).The frequency of haplotype C-A-T-A-A (rs800292-rs1061170-rs10801555-rs10922096-rs2019727) in case group was different from that in control group (corrected P=0.013).Conclusion·The allele polymorphisms of rsl061170 and the haplotype C-A-T-A-A of rs800292-rs 1061170-rs 10801555-rs 10922096-rs2019727 may be associated with schizophrenia in Chinese Han population.

OBJECTIVETo identify potential mutation of SLC22A5 gene in a 5-month-old boy affected with primary carnitine deficiency and provide genetic counseling and prenatal diagnosis for the members of his family.

METHODSDNA was extracted from peripheral blood samples derived from the proband, his parents and elder sister, as well as amniotic fluid from his pregnant mother. All of the 10 exons of the SLC22A5 gene were amplified by PCR and subjected to Sanger sequencing. The amniotic fluid sample was also subjected to G-banded karyotyping and multiplex ligation-dependent probe amplification (MLPA).

RESULTSA homozygous mutation c.760C>T (p.R254X) of the SLC22A5 gene was detected in the proband. Heterozygous mutation c.760C>T (p.R254X) was also found in other family members including the fetus. The karyotyping and chromosomal microdeletion testing for the amniotic fluid sample were both normal.

CONCLUSIONThe newly identified homozygous nonsense c.760C>T (p.R254X) mutation of the SLC22A5 gene probably underlies the primary carnitine deficiency of the proband. Genetic counseling and prenatal diagnosis have been provided for this family.

Objective To explore the feasibility and application in quantifying the rabbit central nervous system by using magnetic resonance diffusion tensor imaging(DTI)sequences.Methods 12 normal New Zealand rabbits were used to scan the brain and spinal cord of rabbits by DTI sequence of 1.5T MR machine,and the normal apparent diffusion coefficient(ADC)and fractional anisotropy (FA)values were obtained in the different regions of the brain and every spinal segment of rabbits,to analyse the characteristics and regularity of numerical changes.Results The average ADC value in the brain of rabbits was (0.87±0.08)×10-3mm2/s,the average FA value was 0.23±0.09;the average ADC value in cervical spinal cord was (1.05±0.14)×10-3mm2/s,the average FA value was 0.55±0.08.The average ADC value in thoracic spinal cord was (1.14±0.12)×10-3mm2/s,and the average FA value was 0.57±0.06;the average ADC value in lumber spinal cord was (1.20±0.12)×10-3mm2/s,and the average FA value was 0.61±0.06.Conclusion FA average value in the brain is lower than that in spinal cord (P<0.001),the difference is related to the distribution of nerve fibers and physiological curvature of spine.ADC average value in the brain is lower than that in spinal cord(P<0.001),this is related to the volume of spinal canal and the peripheral structure of spinal cord.The difference of FA value in the brain and spinal cord is higher than ADC value.

Objective To discuss how to develop the standardized management of medical research contracts in order to promote the policy-making and compliance of hospital scientific contracts management.Methods Through the literature review from the perspective of classified medical research contracts management,along with the analysis of problems raised in regular daily practice,this paper explored how to effectively improve the scientific research management capacity.Results A series of measures such as updating the contract management system,standardizing the management process,improving professional training and implementing the contract archiving can improve the policy-making and compliance of hospital scientific contracts management.Conclusions Standardized hospital scientific contracts management plays significant roles in protecting the interests of both sides,as well as strengthen cooperation.

The suitable experimental animal model is important in research of pathogenesis and therapeutic strategies of diabetic foot ulcer, and the murine model is the most commonly used one at present. It can be divided into two types: the animal model simulating pathological conditions and the model simulating clinical symptoms. This article reviews the current research progress on the mechanisms of diabetic ulcer pathogenesis, and relevant treatment strategies, including the inhibition of matrix metalloproteinases (MMPs) expression, promotion of angiogenesis and anti-inflammatory therapy.
