Objective To quantitatively examine the relationship between xeroderma pigmentosum complementation C group (XPC)rs2228000 (C /T)polymorphism and the susceptibility of breast cancer. Methods The relevant case-control studies published up to December 2015 which investigated XPC rs2228000 (C /T)polymorphism and breast cancer risk were identified by searching PubMed,Cochrane Library,Chinese Biomedical Literature Data,Wanfang Database,China National Knowledge Infrastructure and VIP Database. Meta-analysis was conducted using STATA 12.0 software and odds ratio (OR)with its 95%CI were estimated. Results A total of 8 researches involving 9 case-control studies (3 850 breast cancer cases and 5 047 healthy controls) were included.The Meta-analysis showed that there was statistical association between XPC rs2228000(C /T)variance and breast cancer risk in the homozygous model (TT vs.CC:OR =1.28,95%CI:1.08-1.52,Z =2.80,P =0.005)and recessive model (TT vs.TC +CC:OR =1.23,95%CI:1.05-1.43, Z =2.64,P =0.008),but not in the allele model,heterozygote model and dominant model.In the subgroup of ethnicity and genotyping methods,the different significant correlation was existed between them under Asian and PCR-RFLP in genetic models (T vs.C:OR =1.21,95%CI:1.05-1.40,Z =2.63,P =0.009;TT vs. CC:OR =1.55,95%CI:1.13-2.13,Z =2.70,P =0.007;TT +TC vs.CC:OR =1.26,95%CI:1.02-1.55,Z =2.19,P =0.028;TT vs.TC +CC:OR =1.39,95%CI:1.04-1.87,Z =2.23,P =0.026).We also found significant association between them in subgroup of population-based controls in the homozygous model (TT vs.CC:OR =1.27,95%CI:1.02-1.57,Z =2.16,P =0.031).Conclusion XPC rs2228000 (C /T)polymorphism may be associated with the susceptibility of breast cancer,especially in Asian,and gene-type TT may increase the risk of breast cancer.

Objective To observe the effect of S-adenosyl-L-methionine(SAMe) in treatment of jaundice in newborns and its mechanism.Methods Two hundred and two newborn infants with jaundice were treated with SAMe,76 cases in control group treated with phototherapy and liver enzyme induction elixir;SAMe 30-60 mg/(kg?d) were added to 202 cases intravenously in treatment group.The total biliorubin(T-BILI),direct bilinrubin(D-BILI) and indirect bilinrubin(I-BILI) were dynamically detected.Results Six days after treatment,the skin jaundice index in treatment group decreased remarkably.T-BILI,D-BILI and I-BILI decreased significantly.The curing effectiveness was higher in treatment group than that in control group.The number of applicating blood products and albumin,and blood produets/albumin were decreased in treatment group than those in control group.In those who used glucose to dissolve the SAMe 2.68% had blood-vessel phlebitis.Conclusions SAMe can efficiently quicken the retrogression of jaundice in newborns.It can reduce the use of blood products.It is a reliable and safe drug to treat jaundice in newborns.

Objective To evaluate the effect of therapeutic communication on negative emotion and quality of life of stoke patients. Methods A total of 120 stroke patients were divided into the control group and the observation group equally. The former received routine nursing and the latter routine nursing plus therapeutic communication. After 4 weeks, they were evaluated by self-rating anxiety scale (SAS), self-rating depressive scale (SDS), trait coping style questionnaire (TCSQ) and the short-form health survey-36 (SF-36). Results After the intervention, the scores on anxiety, depression and negative coping in the observation group were lower than those in the control group (P<0.01), while the scores on positive coping and quality of life were higher in the observation group than those in control group (P<0.01). Conclusion Therapeutic communication can effectively improve stroke patients′negative emotion and quality of life.

Objective To compare the clinical effect of preserving the ascending uterine artery in laparoscopic hysterectomy with traditional laparoscopic hysterectomy.Methods 112 patients with various kinds of uterine benign lesions performed by hysterectomy were randomly divided into the preserving the ascending uterine artery in laparoscopic hysterectomy group(observation group,n =60) and traditional laparoscopic hysterectomy group (control group,n =52),The operation time,the intra operative blood loss,the postoperative complications rate and the perimenopausal symptoms in two groups were compared as well as the levels of blood calcium and the levels of hormone before operation,the first month,the sixth month,the first year,and the third year after operation.Results The opreration time [(95.5 ± 22.8) win] and intraoperative blood soss [(81.3 ± 11.6) ml] of the observation group was more than those of the control group [(68.8 ± 7.2) ml] (t =3.772,4.418,all P ＜ 0.05).The postoperative abnormal uniation and defection (1.7％) and fever incidence (1.7％) of the observation group was lower than those of the control group (11.5 ％,13.5 ％) (x2 =4.623,5.843,all P ＜ 0.05).The estradiol level of the observation group began to fall in 6 months postoperative,and had significant differences compare with those of the control group 6 months,1 year,3 years after operation [(328.4 ± 13.4) pmol/L vs (304.8 ± 15.2) pmol/L,(311.3 ± 12.9) pmol/L vs (248.5 ±13.6)pmol/L,(258.3 ± 11.4)pmol/L vs (138.7 ± 12.7)pmol/L] (t =8.758,25.121,52.688,all P ＜0.05).There was significant difference in the level of follicle stimulating hormone (FSH) and luteinizing hormone (LH) between the two groups 1,3 years after operation(t =-90.540,-123.229,-14.757,-19.845,all P ＜ 0.01).There was significant difference in the level of calcium between the two groups 1,3 years after operation(t =3.261,3.050,all P ＜0.05).The perimenopausal symptoms of the observation group was less than those of the control group(x2 =6.142,3.471,4.976,6.646,4.633,all P ＜ 0.05).Conclusion Laparoscopic hysterectomy of preserving the ascending uterine artery is safe and reliable;the recently ovarian function of the patients with hysterectomy is to maximize the preservation in the treatment,the women's quality of life will be to improved.

Objective To explore the difference of abstract color preference among different genders,ages and education levels of hospitalized patients with neurosis.Methods The abstract color preference test was conducted in 223 inpatients with neurosis by adopting the paired comparison method.Results (1) The color preferences order in different genders of neurosis patients tended to be consistent (U=2.606,P＜0.01),green was always the most preferred color,black was the least preferred color,the preference difference had no statistical significance (P＞0.05).(2) The color preferences order in different ages of neurosis patients tended to be consistent(x2 =20.27,P＜0.01).The most preferred color of the patients in 18-30 years old group was yellow,which in ＞ 30 years old group was green,the preference difference had no statistical significance (P＞0.05).(3) The color preferences order in different education years of neurosis patients tended to be consistent(x2 =19.49,P＜0.05).The primary school and illiteracy group preferred red,and the middle school and above group preferred green;the preference difference of orange,white and black in different educational levels of neurosis patients had statistical significance(x2 =6.325,12.491,10.445,P =0.042,0.002,0.005).Conclusion The abstract color preferences of neurosis inpatients with different genders and ages have no obvious difference.The cold and warm color preferences of neurosis patients with different education levels are different.

The event-related potential (ERP) is considered as one of the most effective methods to study and analyze objectively human mental activity based on nerve electrophysiology. At present, ERP is not only used in the study of lie detection, but also in the clinical medicine for the cognitive assessment on patients with cerebrovascular disease, dementia or traumatic brain injury and auxiliary diagnosis of mental illness. With the further development of ERP detection technology, it would have a wider application prospect in the field of forensic medicine.
