Objective To study the relationship between chromosomal abnormality and Y chromosome microdeletions and male infertility. Methods Lymphocytes were cultured from peripheral blood of 1975 male infertility patients and stained with Giemsa. The chromosomes were analyzed under microscope. Y chromosome specific sequence tags (STS) were selected, then the Y chromosome microdeletions in AZF regions were screened by polymerase chain reaction (PCR) in azoospermia and oligozoospermia patients. Results There were 305 cases of detected chromosomal abnormalities (15.44%) in the 1975 cases. There were 101 cases (5.11 %) with autosome abnormalities which clinically manifested as oligozoospermia and teratospermia. There were 204 cases (10. 33%) of sexual chromosome abnormalities and the patients were mainly characterized with Klinefelter's syndrome. Y chromosome microdeletions were detected in 109 (14.97 %) of the 728 cases of azoospermia or oligozoospermia. The most common microdeletion of Y chromosome was AZFc (62.39%) and these patients were characterized with azoospermia and oligozoospermia. Five patients (4. 59%) who suffered Y chromosome microdeletion in AZFa region and AZFb region were characterized with azoospermia. Fifteen cases (13.76%) with microdeletion in AZFb region and AZFc region were mainly characterized with azoospermia. There were 6 cases (5. 50 % ) of microdeletion in AZFa, AZFb and AZFc regions,these patients were all characterized with azoospermia. Conclusions Both Chromosome abnormalities and Y chromosome microdeletions are important causes for male infertility.

Objective To investigate the effect of Roy Adaptation Model(RAM)in patients with adolescent insanity.Methods One hundred patients with adolescent insanity during October 2011 to March 2012 were randomized in equal number into two groups by random digit table:the study group and the control group.The former were intervened with RAM and the latter received routine care and health education.Seven weeks after intervention,Hamilton Depression Rating Scale(HAMD),Hamilton Anxiety Scale(HAMA) and Observation Scale(NOSIE)were used for the assessment. Results After intervention,the scores on HAMD and HAMA in the study group were significantly lower,compared to the control group(P<0.01).The scores on social function,social interest,subjective support and use of social support were all significantly higher than those of the control group(all P<0.01). Conclusions RAM can improve their ability of the patients with adolescent insanity to adapt to the environment.It may improve their mental state and their quality of life.

Objective To evaluate the application of mind map on patients with urinary continence after benign prostate hyperplasia ( BPH ) surgery and provide clinical evidence for improving the quality of postoperative nursing.Methods From February 2013 to April 2014, we selected 160 cases who suffered BPH, divided into experimental group and control group on average by method of random number table.The control group received routine nursing while the experimental group built up mind map of urinary continence and utilized it to take care of patients.Patients in two groups had been observed and recorded their rate, length, amount and frequency of urinary continence.IPSS, ICI-Q-SF and the effective factors of urinary continence after BPH surgery questionnaire had been made use of urinary continence reason investigation.Results Ten cases (12.5%) occurred urinary continence and lasted (4.1 ±2.8) d in the experimental group while those of data were 25 cases (31.2%),(6.8 ±3.4)d in the control group (χ2/t=8.23,2.63, respectively;P<0.05).The frequency and amount of urinary continence in experimental group were lower than those in the control group, the difference were statistically significant (χ2 =4.37,5.24, respectively; P<0.05).The satisfaction and the degree of comfort in the experimental group were higher than those in the control group ( P <0.05 ). Conclusions Mind map can effectively reduce the rate and length of urinary continence for patients after BPH surgery, and contribute to patients′quality of life and satisfaction.
