Objective To discuss the effect of self- care education at the early time of postoperation and the use of nursing packages during the later period on non- throat patients. Methods 40 patients having un-dergone total laryngectomy were divided into the control group and the experimental group according to the surgery date with 20 cases in each group. The control group received conventional nursing, while the experi-mental group was given the system intervention by specialized nurses. The intervention content included self-care education at the early time of postoperation and the use of nursing packages during the later period. The questionnaire survey was carried out 15 days and 3 months after operation.The coping style,self-care ability and survival quality were compared between the two groups. Results The comparison of coping style showed re-markable difference in the two groups. The comparison of self- care ability and level of health knowledge showed significant difference 15 days after operation except two other items,but the four items demonstrated significant difference 3 months after operation. Difference also existed in the total scorn of survival quality. Conclusions Early system serf- care education after operation and the use of nursing package during the later period can impel the patients to cope positively, enhance self-care ability and survival quality.

Objective To evaluate the efficacy of probiotics on chemotherapy-induced intestinal mucositis in rats.Methods The databases including PubMed,EMbase,Cochrane,CBM,CNKI,WanFang and VIP were retrieved from their establishment to April 2016.The related randomized controlled trials(RCT) on the effects of probiotics for treating chemotherapy-induced intestinal mocositis in rats were included.The relevant literatures were screened according to the inclusion and exclusion criteria,then the data were extracted and analyzed.Results Total 6 RCT were included.Compared with the control group,the intestinal secretion and absorption function in the probiotics group was strengtnened[SMD=1.73,95 ％CI(0.79,2.68),P＜0.01],jejunal anti-oxidant capacity was increased [SMD=-2.12,95％CI(-3.56,-0.67),P＜0.01],however low dose probiotics (＜1 × 109 cfu/d)had no protective effect on small intestine[SMDjejunum =-0.06,95％CI(-0.51,0.40),SMDileum =0.02,95％ CI(-0.71,0.75);P ＞0.05],while high dose probiotics(≥ 1 × 109 cfu/d) could reduce the intestinal pathological damage[SMDjejunum =-0.64,95 ％ CI (-1.20,-0.09),SMDileum=-0.85,95％ CI(-1.59,-0.12);P＜0.05].Conclusion High dose probiotics can reduce chemotherapy-induced intestinal mucositis in rats.Because of less included literatures and the influence of publication bias,the effect of probiotics on chemotherapy induced mucositis could be overestimated.

Objective To study the correlation between thyroid autoantibodies anti‐thyroid peroxidase antibody (TPOAb) with recurrent miscarriage to seek the objective data indicator for clinical diagnosis of recurrent miscarriage .Methods A total of 1 016 pregnant women of physical examination and normal thyroid function in the obstetric and gynecologic clinic of our hospital from March 2012 to May 2014 were selected as the research subjects .Among them ,90 cases of abortion were screened out and di‐vided into the primary abortion group(60 cases) and the recurrent abortion group(30 cases) .90 healthy childbearing age women of physical examination were selected as the control group .The positive TPOAb cases were performed statistics and compared among various groups ,the ratio was calculated;the TPOAb level was recorded in each group .At the same time the correlation between TPOAb with recurrent abortion was analyzed .Results The TPOAb positive rate in the recurrent abortion group was 46 .67% , which was significantly higher than 25 .00% in the primary abortion group and 4 .44% in the control group;at the same time the TPOAb positive rate of primary abortion group was also significantly higher than that of the control group ,the difference had sta‐tistical significance (P<0 .05) .The TPOAb concentration level in the recurrent abortion group was significantly higher than that in the primary abortion group and the control group;the TPOAb concentration level in the primary abortion group was also signifi‐cantly higher than that in the control group ,the differences were statistically significant (P< 0 .05) .In the follow‐up of adverse pregnancy occurrence with recurrent abortion as the adverse pregnancy event ,and according to the method of Spearman correlation analysis ,with the increase of TPOAb level ,the occurrence rate of recurrent miscarriage was higher ,which showed the positive cor‐relation(r=0 .764 ,P=0 .000) .Conclusion Monitoring the patient′s TPOAb level can better show the symptoms of recurrent abor‐tion .

miR-122 is the most abundant miRNA in adult human liver. To study the functions of miR-122 in liver disease, we amplified the precursor of human miR-122 gene by polymerase chain reaction (PCR) from the HepG2 genomic DNA, and then constructed miR-122 expression vector pLMP-miR-122. pLMP-miR-122 could overexpress mature miR-122 when human normal liver cells L-O2 and the hepatoma cells HepG2 were transfected with it. When HepG2 cells were co-transfected with HBV1.3 and pLMP-miR-122, we found that miR-122 could down-regulate the expression of HBs and HBe antigen. These results showed that the human liver specific miR-122 expression vector was constructed successfully, and it could regulate the replication and the expression of HBV genes. The plasmid pLMP-miR-122 will facilitate further studies of the functions of miR-122 in the development of liver virus infection diseases and HCC.
