Objective To observe the effect of auricular point sticking plus breast massage with rehabilitation apparatus on lactation in the puerperant. Methods Totally 127 in-hospital primiparae were randomized into a treatment group of 62 cases and a control group of 65 cases. The control group was intervened by conventional nursing care, while the treatment group was by auricular point sticking plus breast massage with rehabilitation apparatus in addition to the conventional nursing care. The lactation yield, initial lactation time, and the change of prolactin (PRL) were observed. Results There were significant differences in comparing the lactation yield grading and initial lactation time between the two groups (P＜0.05). There were significant differences in comparing the serum PRL level on the postpartum day 1, 2, and 5 between the two groups (P＜0.01, P＜0.05). Conclusion Auricular point sticking plus breast massage with rehabilitation apparatus can promote milk secretion, the initial lactation time, PRL production, and the breast feeding rate.

OBJECTIVE To investigate the clinical and etiologic characteristics and treatment of central venous catheter-related(sepsis).METHODS Forty cases of patients with central venous catheter-related sepsis and their clinical manifestation,etiologic profiles and outcome of treatment were retrospectively analyzed.RESULTS Forty six strains were isolated including 23 strains of Gram-positive cocci,19 of Gram-negative bacilli and 4 of fungi.The most frequent(isolates) were Staphylococcus epidermidis.CONCLUSIONS The most common organism causing CRS is S.epidermidis;the key preventive measure is to avoid inner and outer pollution of catheter;antibiotic lock-technique can be taken for the treatment of uncertain CRS.If it is no effect after 24-48 hours,it is necessary to remove venous catheter promptly.

Objective To investigate the effect of all-trans retinoic acid (ATRA) on transforming growth factor β1 (TGF-β1)/Notch signaling pathway in injured podocytes induced by adriamycin (ADR) in vitro.Methods Podocytes cultured in vitro were randomly divided into normal group,model group,ATRA treatment control group,12-hour ATRA intervention group and 24-hour ATRA intervention group.Morphological changes were observed by using light microscope.The expressions of TGF-β1,podocin,Notch 1,Jagged 1 mRNA were evaluated through real-time polymerase chain reaction (RT-PCR) and the corresponding proteins were detected by using Western blot.Results (1) No obvious changes between normal group and ATRA treatment control group were revealed as the plump podocytes and distinct outline were found in light microscope,while podocytes in model group showed disordered arrangement,fuzzy boundary,atrophy,hypertrophy and increased cellular debris.Of note,the podocytes in 12-hour ATRA intervention group and 24-hour ATRA intervention group almost returned to normal.(2) In contrast with those in model group,the amounts of TGF-β1,Notchl,Jaggedl mRNA levels decreased in 12-hour ATRA intervention group (1.34 ±0.43 vs.4.16 ±0.31,1.67 ±0.2 vs.4.21 ±0.92,2.08 ±0.27 vs.5.14 ±0.63,q =23.83,11.45,19.67,all P ＜0.05) and 24-hour ATRA intervention group (1.22 ± 0.16 vs.4.16 ± 0.31,1.73 ± 0.53 vs.4.21 ± 0.92,2.08 ± 0.29 vs.5.14 ± 0.63,q =24.85,11.18,19.67,all P ＜ 0.05),and the differences were significant;similar trend was detected in the protein levels (1.04 ± 0.03 vs.4.31 ± 0.10,1.06 ± 0.04 vs.4.47 ± 0.24,1.07 ± 0.04 vs.4.20 ± 0.16,1.06 ±0.03 vs.4.31 ±0.10,1.07 ±0.03 vs.4.47 ±0.24,1.09 ±0.03 vs.4.20 ±0.16,q =163.50,69.61,90.36,162.50,69.40,89.78,all P ＜ 0.05),and the differences were significant;whereas the level of podocin mRNA (1.13 ±0.05 vs.0.40 ± 0.06,1.16 ± 0.03 vs.0.40 ± 0.06,q =36.50,38.00,all P ＜ 0.05) and protein (1.01 ± 0.01 vs.0.44 ±0.01,1.02 ±0.01 vs.0.44 ±0.01,q =180.25,183.41,all P ＜0.05) increased,and the differences were sig nificant.(3) The expressions of Notch1,Jagged1 mRNA were positively correlated with TGF-β1 mRNA (r =0.84,1.00,all P ＜ 0.05),but negatively correlated with podocin mRNA (r =-0.95,-0.94,all P ＜ 0.05) in model group.Conclusions ATRA might alleviate podocyte injury through cutting the expressions of TGF-β1,Notch1,Jagged1 and raising the expression of podocin in injured podocytes induced by ADR.

In order to screen antigenic genes of Clonorchis sinensis (C.sinensis).Firstly,a cDNA expression library from adult worms of C.sinensis was successfully constructed with lambda ZAP express vector.Total RNA of C.sinensis adult worms were extracted by the Trizol reagent and mRNA were further purified through oligo-dT cellulose.The first strand eDNA was synthesized by using MMLV reverse transcriptase.After the synthesis of the second strand,the cDNA were purified by CHROMA SPIN-400 kit and then ligated with lambda ZAP express vector,then packaged in vitro and amplified.The original library contained 1.5 × 106 pfu cDNA clones,the titer of amplified library reached 1.5 × 1010 pfu/mL,in which about 99% clones were recombinants and most of insert DNA fragments were 0.4-2.0 kb.Secondly,immunoscreened using the naturely infected man serum from C.sinensis.The positive clones were sequenced and analyzed.From 2.0 × 105 recombinant clones of the eDNA library,41 positive clones were obtained.Sequence analysis indicated that the cDNAs encoded proteins including glycine rich antigen 2,proline rich antigen 2 and antigen Cs44 from C.sinensis,anothers were lower similarity to predicted protein from Nematostella vectensis,transcription elongation factor GreA from Bartonella quintana str.Toulouse and NM_132090 CG3446 gene product in Drosophila melanogaster from Schistosoma japonicum.These data may form a foundation for identifying recombinant antigens that can be used in the diagnosis or vaccination against clonorchiasis.

Objective To explore the effects of Living with Hope Program(LWHP) on family caregivers of patients with advanced lung cancer.Methods Totally 60 family caregivers of patients with advanced lung cancer were randomly divided into the experimental group and the control group.The experimental group received LWHP intervention and routine care knowledge education,the control group only received routine care knowledge education.Hope,self-efficacy,anxiety and depression,and quality of life were evaluated at the first week,the second week,the first month,and the third month.Differences between two groups were compared using variance analysis of repeated measurements.Results The self-evaluation of the intervention was 76.6％,and the main effects of hope level,selfefficacy,anxiety and depression,and mental health were statistically significant (P＜0.05);the time effect on hope level and self-efficacy were statistically significant (P＜0.05);there were interaction effects between intervention and time on hope level,self-efficacy,anxiety and depression,and mental health (P＜0.05).Conclusion LWHP can effectively improve hope level,self-efficacy and mental health status,and alleviate anxiety and depression of family caregivers of patients with advanced lung cancer.
