Objective To explore the application of transitional care based on the Omaha system in postoperative rehabilitation of patients with breast cancer.Methods Seventy-two patients after radical mastectomy were assigned into two groups according to admission time,patients from June to December 2011 were set as the control group,patients from February to December 2012 were assigned to the intervention group,each group contained 36 patients.The patients in the control group received routine nursing,while patients in the intervention group were implemented transitional care program with Omaha system as framework from before discharge to 6-week follow-up after discharge from hospital.Nursing effect was compared between two groups from three aspects such as cognition,behavior and status.Results Twenty-three problems were found in the 6-week follow-up for the intervention group,including environmental domain,psychosocial domain,physiological domain and health-related behavior domain.Knowledge,behavior and status scores of the intervention group 6 weeks after discharge were significantly higher than those of the control group [(3.92 ± 0.48) scores vs.(2.41 ± 0.17) scores,(4.11 ± 0.49) scores vs.(2.83 ± 0.25) scores,(3.09 ±0.52) scores vs.(2.32 ±0.39) scores,t=14.81,15.36,9.42,P＜0.01 or 0.05].Conclusions Transitional care based on the Omaha system shows common problems in rehabilitation of patients with breast cancer after operation,and provides standardized program for rehabilitation nursing.It can achieve better nursing effect.

Objective:To observe the effect of low-intensity pulsed ultrasound (LIPUS) at different intensities on the expression of adiponectin and its receptors in C2C12 myoblasts, and to explore the potential mechanism by which LIPUS promotes the differentiation of C2C12 myoblasts.Methods:C2C12 myoblasts cultured in vitro were randomly divided into a control group and U 0.1, U 0.3 and U 0.5 groups. The control group received sham LIPUS exposure, while the U 0.1, U 0.3 and U 0.5 groups were exposed to LIPUS at intensities of 0.1W/cm 2, 0.3W/cm 2 or 0.5W/cm 2 respectively, and 1MHz for 5 min daily for 5 days. Cell viability was measured using CCK-8 assays. Fluorescence quantitative reverse transcription-polymerase chain reactions were used to detect the mRNA expression of adiponectin, adiponectin receptor 1 (adipoR1) and T-cadherin in the cells. Western blotting was employed to assess the protein expression of adiponectin, adipoR1, T-cadherin, adenosine monophosphate activated protein kinase (AMPK), activated phosphorylated adenylate-activated protein kinase (P-AMPK), embryonic myosin heavy chain (eMHC) and myogenin (MYOG). The differentiation ability of the 4 groups was measured using cell immunofluorescence chemistry. Results:After the intervention the cell viability in the U 0.1, U 0.3 and U 0.5 groups was significantly higher than in the control group. Compared with the control group, the average mRNA expression of adiponectin and the receptors of adipoR1 and T-cadherin were up-regulated significantly in the U 0.3 and U 0.5 groups. The average adiponectin, adipoR1 and T-cadherin protein expressions, and the AMPK phosphorylation level in the U 0.3 and U 0.5 groups had increased significantly compared with the control group, but all were significantly lower than in the U 0.3 group. The average protein expression of eMHC and MYOG, and the C2C12 myoblast fusion indices of the U 0.3 and U 0.5 groups were significantly higher the control group′s averages. Conclusions:LIPUS can promote the differentiation of C2C12 myoblasts. It is most effective at 0.3W/cm 2, administered for 5min/d at 1MHz with a 20% duty cycle. Its regulatory mechanism may be related to up-regulation of the expression of adiponectin, the adipoR1 and T-cadherin receptors, and the activation of AMPK phosphorylation in C2C12 myoblasts.

Objective To evaluate the association between interleukin-I(IL-1)loci polymorphisms and increased risk of gastric carcinoma in samples from northern Chinese population.Methods Blood sam- ples from 126 patients with gastric cancer and 125 controls with chronic gastritis were collected.Genomic DNA was extracted and polymorphisms at -31(C to T),-511(C to T)and at intron 2(86-bp VNTR)of IL-I RN were genotyped by PCR-CTPP,PCR-RFLP and PCR.For detection of Hp infection fast urenase test,~(14)C breath test and serum anti-Hp IgG antibody assay were used.Results Five kinds of polymorphism of IL-IRN were found as 1/1,1/3,1/4,1/2 and 2/2,and the frequencies in patients were 76.19%、4.76%、6.35%、11.90% and 0.79%,respectively.However,the frequencies in controls were 76.00%、4.00%、4.80%、13.60% and 1.60%.No significant differences were observed between cases and controls in each genotype.The polymorphism of IL-IB-31 allele was C/C,C/T and T/T.The frequencies in patients were 12.70% ,47.62% and 39.68%,and in controls 28.00%,48.80% and 23.20% respectively.IL-1B- 31 T/T carriers were at an increase risk of gastric cancer with an odds ratio of 3.772(95% CI,1.786- 7.966).IL-IB-511 alleles were C/C,C/T and T/T.The frequencies in patients were 19.20%,56.80% and 24.00% and in controls,23.38%,49.19% and 27.42% respectively.No significant differences were observed between cases and controls in each genotype.Conclusion In Chinese population,the polymor- phism of IL-1B-31 alleles may be associated with the susceptibility of gastric cancer.However,no evidence was found to support that the polymorphisms of IL-1RN and IL-I B-511 alleles had relationship with gastric cancer.

Objective To establish an ultraviolet-irradiation damage model in cultured fibroblasts derived from human skin and to explore the potential protective effects and mechanisms of amyloid precursor protein 17-met peptide (APP17-mer peptide) on the oxidative damage and collagen metabolism in cultured fibroblasts after ultraviolet irradiation. Methods Human dermal fibroblast cultures were established by outgrowth from foreskin biopsies of a healthy donor and were irradiated by a single exposure to ultraviolet rays and cultured in a series of concentrations of APP17-mer peptide (0, 20, 40, 80 μmol/L).The activity of fibroblasts was detected by the assay of MTT. The intracellular ROS level was measured with a confocal microscope. The expression of MMP-1 mRNA was analyzed real-time quantitatively following RT-PCR. Results Primary cultures of human skin fibroblasts were established from human foreskin in DMEM supplemented with 10 % fetal bovine serum. UV irradiation depressed cellular activity and increased intracellular level of ROS (P<0.05). 40μmol/L and 80μmol/L APP17-mer peptide increased the cellular activity in both UV irradiated fibroblasts and unirradiated fibroblasts (P<0.05), however,20 μmol/L did not show such protective effects (P>0. 05). 40μmol/L APP17-mer peptide could depress the level of ROS in irradiated libroblasts. A single exposure of fibroblasts to UV irradiation resulted in 1.78 foldup-regulation of MMP-1 mRNA compared with unirradiated sample, 40μmol/L and 80μmol/L APP17-mer peptide decreased the expression of MMP-1 mRNA (P<0.05 and P<0.01, respectively).Conclusion APP17-mer peptide can enhance cellular activity under UV-induced oxidative stress and in-hibit collagen degradation in fibroblasts irradiated with ultraviolet rays. Inhibition of ROS production may be involved in the protective mechanism of APP17 peptide.

Background The data on the prognostic values of high sensitivity C-reactive protein (hsCRP) levels in patients with advanced symp-tomatic heart failure (HF) receiving cardiac resynchronization therapy (CRT) are scarce. The aim of present study was to investigate the association of serum hsCRP levels with left ventricle reverse remodeling after six months of CRT as well as long-term outcome. Methods A total of 232 CRT patients were included. The assessment of hsCRP values, clinical status and echocardiographic data were performed at baseline and after six months of CRT. Long-term follow-up included all-cause mortality and hospitalizations for HF. Results During the mean follow-up periods of 31.3 ± 31.5 months, elevated hsCRP (>3 mg/L) prior to CRT was associated with a significant 2.39-fold increase (P=0.006) in the risk of death or HF hospitalizations. At 6-month follow-up, patients who responded to CRT showed significant reductions or maintained low in hsCRP levels (–0.5 ± 4.1 mg/L reduction) compared with non-responders (1.7 ± 6.1 mg/L increase, P=0.018). Com-pared with patients in whom 6-month hsCRP levels were reduced or remained low, patients in whom 6-month hsCRP levels were increased or maintained high experienced a significantly higher risk of subsequent death or HF hospitalizations (Log-rank P<0.001). The echocardio-graphic improvement was also better among patients in whom 6-month hsCRP levels were reduced or remained low compared to those in whom 6-month hsCRP levels were raised or maintained high. Conclusions Our findings demonstrated that measurement of baseline and follow-up hsCRP levels may be useful as prognostic markers for timely potential risk stratification and subsequent appropriate treatment strategies in patients with advanced HF undergoing CRT.

Semisupervisedmakesfulluseoflargeamountsofunlabeledsamplestomakeuptheinsufficiency of labeled samples. Since it is difficult to obtain a large number of accurate labeled samples and it is a good way for modeling by using a small amount of labeled samples or a large number of inaccurate samples, we proposed a new method named as semi-supervised partial least squares ( SS-PLS) to optimize model based on semi supervised learning. We used 211 samples of tobacco near infrared spectrum and sensory evaluation for modeling and used SS-PLS method to optimize tobacco sensory evaluation model. In the optimized model, the coefficient of determination ( R2 ) can reach up to 90%, the ratio of performance to deviation ( RPD) can reach up to 3 . 0 , and the standard error of cross validation and the standard error of prediction ( SECV and SEP) are below 1. 0. We divided the original sensory evaluation and SS-PLS optimized data into three grades of excellent, medium and poor in accordance with the fixed threshold, the result using projection model of based on principal component and Fisher criterion ( PPF ) shows that the classification of SS-PLS optimized data is better than the original sensory evaluation data. The SS-PLS method can solve the data representation problem of using small sample set for modeling and provides a new chemometrics method for near infrared spectroscopy modeling in case of obtaining a large number of accurately labeled samples is difficult.

OBJECTIVE: To evaluate the inhibiting effects of the root of Mallotus apelta (Lour.) Muell.-Arg. on duck hepatitis B virus (D-HBV) in vivo. METHODS: Forty nestling ducks with congenitally infection of D-HBV detected by PCR were randomly divided into five groups: untreated group, lamivudine-treated group, and high-, medium- and low-dose root of Mallotus apelta-treated groups. The ducks in the lamivudine-treated group were fed lamivudine with a dose of 50 mg/kg once. Ducks in the three-dose Mallotus apelta-treated groups were treated with different doses of decoction of this herbal medicine for 21 days respectively. The serum content of D-HBV DNA was determined by quantitative real-time PCR technique before and 7 days after the treatment, and on the 7th, 14th and 21st day of the treatment. Liver biopsy was also executed before and after the treatment to observe the histopathological changes. RESULTS: Lamivudine showed a rapid inhibiting effect on D-HBV DNA, but this effect didn't last long, and the serum level of D-HBV DNA increased again after treatment. The serum level of D-HBV DNA dropped markedly in the high- and medium-dose Mallotus apelta-treated groups on the 14th and 21st day. Low-dose Mallotus apelta revealed no obvious inhibiting effect on D-HBV. After treatment, the inhibiting effect in the root of Mallotus apelta-treated group continued as compared with that in the untreated group. The histopathological changes of liver tissues showed that the inflammation in the high-dose root of Mallotus apelta-treated group was weakened as compared with that in the lamivudine-treated group. CONCLUSION: The root of Mallotus apelta has therapeutic effect on D-HBV. It can restrain the duplication of D-HBV in vivo. Although this effect is weaker than that of lamivudine, it continues longer. Thus this herbal medicine is an effective, safe and economical drug for hepatitis B.

OBJECTIVETo observe the clinical therapeutic effect of Nuzhen Yunyu Decoction (NYD, a Chinese recipe for nourishing blood and reinforcing Shen) and its influence on the hemodynamic parameters in ovarian and uterine arteries.

METHODSSixty-eight patients were randomly divided into two groups at the ratio of 2:1, 45 in the TCM group treated with Chinese medicine and 23 in the control group treated with clomiphene citrate. Menstrual cycle were taken as the indexes for clinical observation; basal body temperature, cervical mucus, vaginal exfoliative cells, serum hormones and B ultrasonic examination were taken as the indexes for ovulation and pregnancy assessment. The hemodynamic parameters of uterus and ovary were determined by using color Doppler ultrasonography, and the growth of follicles and ovulation, thickness of uterine endometrium were also monitored continuously.

RESULTSResults of 3 cycles treatment and 1 year follow-up study showed that the ovulation promoting rate, pregnancy rate and abortion rate in the two groups were similar, but the treated group showed better effects than that of control group, in such aspects as regulating menstruation, promoting growth and development of follicle, strengthening endometrium, improving blood supply and circulation of uterine and ovary (P < 0.05, P < 0.01).

CONCLUSIONNYD has the effects of ovulation promotion and holistic regulation of reproductive system.

OBJECTIVETo investigate the clinicopathological features of testicular malignant Leydig cell tumor (TMLCT) and improve the non-invasive diagnosis of the disease.

METHODSWe retrospectively analyzed the clinicopathological data on a case of TMLCT, detected the circulating tumor cells (CTC) in the peripheral venous blood, and reviewed the related literature.

RESULTSThe patient, a 47-year-old male, underwent radical orchidoepididymectomy under general anesthesia. Postoperative pathology confirmed the lesion to be TMLCT, which was mainly composed of Leydig cells and suspected with vessel carcinoma embolus. Immunohistochemistry showed the tumor cells to be positive for α-inhibin, Ki67, CD30, vimentin, EMA, and PLAP, but negative for CK, CK7, S100, CD10, SMA, Des, AFP, hCG, CEA, CK19, CD117, Oct-4, LCA, CD20, Pax-5, CD3, and CD43. Two CTCs were detected in the peripheral venous blood. The patient received 3 courses of chemotherapy for retroperitoneal multiple lymph nodes metastasis post-operatively. Subsequent CT imaging manifested no obvious reduction of the retroperitoneal lymph nodes and consequently the patient again underwent retroperitoneal lymphadenectomy and cryoablation. At 8 months after treatment, CT examination revealed notably enlarged retroperitoneal lymph nodes with the right adrenal gland evidently invaded.

CONCLUSIONTMLCT is an extremely rare sex-gonad stromal tumor with high malignancy and poor prognosis, and CTCs may be used for its early diagnosis and prognostic prediction.
