Objective To investigate early nasogastric nutrition on patients with acute decompensated chronic heart failure,and observe its influence on patient's disease outcome.Methods From January 2012 to December 2013,100 cases with acute decompensated chronic heart failure were used as the research subjects,were randomly divided into experimental and control groups with 50 cases each group.Patients of two groups adopt expansion of blood vessels,strong heart,diuresis,and routine anti-infection treatment;Based on this scheme,experimental group adopt early nasogastric nutrition.The cardiac function index,the change of nutritional status and clinical curative effect and the result of follow-up within 1 year after discharge of two groups were compared.Results Left ventricular end-diastolic dimension (LVEDD) and left ventricular end-systolic dimension (LVESD) in two groups after treatment were decreased,and the descender of experimental group was superior to that of the control group with statistically significant difference (P ＜ 0.05).After treatment,left ventricular ejection fractions (LVEF) of two groups were improved,and the rise of experimental group was superior to that of control group with statistically significant difference (P ＜0.05).In the two groups after treatment,the serum brain natriuretic peptide (BNP) levels were significantly decreased,and the descender of the experimental group was more than that of control group with statistically significant difference (P ＜ 0.05).After treatment,body mass index (BMI),the level of serum prealbumin (PA),transferrin (TRF),and the total number of lymphocytes of two groups were increased significantly (P ＜ 0.05);and BMI,the level of serum PA and TRF,and the total number of lymphocytes of the experimental group were significantly better than those of the control group (P ＜ 0.05).The total effective rate of the experimental group was significantly higher than that of the control group (P ＜ 0.05).The exacerbation rates,readmission and mortality rate of experimental group follow-up within 1 year after discharge were significantly lower than that of the control group (P ＜ 0.05).Conclusions The early nasogastric nutrition on the patients with acute decompensated chronic heart failure was better able to improve patients' nutrition state,more conducive to patients with cardiac function recovery,improve the clinical curative effect,and reduce the exacerbation rates,and readmission and mortality rate.

Objective To investigate whether functional Wnt-?-catenin signaling is present in activated hepatic stellate cells (HSC),and the effect of blocking this signaling on activation of HSC. Methods?-catenin expression in HSC was examined by immunocytochemistry.Wnt signalings in HSC-T6 were assessed using a T cell factor (TCF)-dependent luciferase reporter gene (pTOP- FLASH) assay.Wnt signalings in HSC-T6 were blocked by transfecting with a dominant negative TCF (dnTCF) expression plasmid,then the expression of alpha smooth muscle actin (?-SMA) and collagen typeⅠwere examined by Western blot.Results?-catenin staining was positive in the nuclei of HSC-T6.Luciferase activity in the cells transfected with pTOPFLASH was significantly higher than that in the cells transfected with pFOPFLASH (P

Background Researches showed that the content of nitric oxide (NO) and nitric oxide synthetase (NOS) increases in blood,aqueous humor and tear of cataract patient.But the function of NO and NOS in cataract formation is still elusive.Objective The aim of this study was to explore the prevention and treatment effect of NOS inhibitor,1-nitro-arginine methyl ester (L-NAME),on galactose cataract.Methods Sixty clean three-week-old Wistar rats were equally and randomly divided into 3 groups.0.9％ Normal saline solution (30 ml/kg) was subcutaneously injected every day for 30 days in the rats of the control group,and 50％ of D-galactose solution (30 ml/kg) was used in the rats of the model and L-NAME group at the same way.L-NAME eye drops was simultaneously administered in the L-NAME group 3 times per day for 30 days.The eyes of the rats were examined under the slit lamp in 10,20 and 30 days,and the degree of lens opacification was scored.Lenses of the rats were obtained at the end of this experiment for the detect of NO,NOS contents.Flow cytometry was used to assay the caspase-3 level of rat lens.Repeated measurement two factor analysis of variance was used to analyze the difference of lens opacification scores in different groups and different time points,and one-way ANOVA was used to analyze the differences of NO,NOS and caspase-3 contents in lens among the groups.Results Lens opacification appeared in 10 days after injection of 50％ D-galactose solution in the rats of the model group and L-NAME group.Lens opacification score was higher among the different groups and different time points (Ftime =435.251,P =0.000 ;Fgroup =395.120,P=0.000).NO content in the lens was (0.45±0.15) μmol/g,(2.67 ± 0.47) μmol/g and (1.68±0.34) μmol/g in the control group,model group and L-NAME group,showing a significant difference (F=58.872,P=0.000).The NOS contents in the lens was (0.0160±0.0020) U/ml,(0.0370±0.0040) U/ml and (0.0270±0.0010) U/ml in the control group,model group and L-NAME group,showing a significant difference (F =66.174,P=0.000).Caspase-3 contents in the lens was (339.4 ± 37.9),(697.7 ± 46.5) and (650.7 ± 53.1),Showing a significant difference among them (F =100.005,P =0.000).Conclusions The increase of NO,NOS and caspase3 levels are associated with lens opacification.Topical administration of L-NAME eye drops can down-regulate NOS content in lens,reduce the NO formation and inhibit the apoptosis of lens epithelial cells.

· AIM: To investigate the complications of intravitreal triamsinolone acetonide (TA) injection in vitrectomy for proliferative diabetic retinopathy (PDR).· METHODS: From February 2005 to January 2007, 18patients (18 eyes) with PDR who were injected with TA in vitrectomy were observed retrospectively after surgery.· RESULTS: During a postoperative follow-up period of 3 to 6 months (mean 4.6 months), some complications including deposit of TA granules on the macular region and surface of the retina (3 eyes), postoperative vitreous hemorrhage (3eyes), elevated intraocular pressure (2 eyes) and pseudohypopyon (1 eye)were observed.· CONCLUSION: The complications after surgery such as deposit of TA granules on the macular region and surface of the retina and pseudohypopyon could be cured without any special treatment. All eyes with elevated intraocular pressure after surgery were controlled by drug. Re-operation may be an effective method for patients with unabsorbable vitreous hemorrhage after vitrectomy.

OBJECTIVETo evaluate the outcomes of T3a prostate cancer with unfavorable prognostic factors treated with permanent interstitial brachytherapy combined with external radiotherapy and hormone therapy.

METHODSFrom January 2003 to December 2008, 38 patients classified as T3a prostate cancer with unfavorable prognostic factors were treated with trimodality therapy (brachytherapy + external radiotherapy + hormone therapy). The prescription dose of brachytherapy and external radiotherapy were 110 Gy and 45 Gy, respectively. The duration of hormone therapy was 2-3 years. The endpoints of this study included biochemical failure-free survival (BFFS), distant metastasis-free survival (DMFS), cancer-specific survival (CSS), and overall survival (OS). Survival curves were calculated using the Kaplan-Meier method. The Log-rank test was used to identify the prognostic predictors for univariate analysis.

RESULTSThe median follow-up was 71 months. The serum pre-treatment prostate-specific antigen (PSA) level ranged from 10.0 to 99.8 ng/ml (mean 56.3 ng/ml), the Gleason score ranged from 5 to 9 (median 8), and the percentage of positive biopsy cores ranged from 10% to 100% (mean 65%). The 5-year BFFS, DMFS, CSS, and OS rates were 44%, 69%, 82%, and 76%, respectively. All biochemical failures occurred within 40 months. The percentage of positive biopsy cores was significantly correlated with BFFS, DMFS, and OS (all P=0.000), and the Gleason score with DMFS (P=0.000) and OS (P=0.001).

CONCLUSIONST3a prostate cancer with unfavorable prognostic factors presents not so optimistic outcome. Hormone therapy should be applied to prolong the biochemical progression-free or metastasis-free survival. The percentage of positive biopsy cores and the Gleason score are significant prognostic factors.

OBJECTIVE The aim of the present study was to evaluate the protective effects of momordica charantia polysaccharides(MCP)on depressive animal model induced by chronic social defeat stress(CSDS)and explore the underlying mechanisms.METHODS We established CSDS depressant mouse model and treated CSDS mice with MCP.Sucrose preference,forced swim test(FST)and social interaction test(SIT)were used to measure behaviors changes.We used ELISA,Q-PCR and western blot to test the levels of cytokines in the hippocampus. RESULTS The results showed that chronic administration of MCP(100,200 and 400 mg·kg-1)significantly prevented depressive-like behaviors in mice as assessed by social interaction (SIT), tail suspension (TST) and sucrose preference tests (SPT).It was showed that the elevation of proinflammatory cytokines(TNF-α,IL-6,and IL-β)concentra-tions,up-regulation of JNK3,c-Jun,and P-110β protein expressions in the hippocampus of CSDS model. Moreover,reduction activity of PI3K and phosphorylation level of protein kinase B(AKT)was also observed in the hippocampus of CSDS model.All above phenomenon were reversed after MCP intervened.Further-more,the protective effects of MCP on the CSDS mice were partly inhibited by the specific phosphati-dylinositol 3-kinase (PI3K)inhibitor, LY294002. CONCLUSION The protective effects of MCP against depressive-like effects in CSDS mice might reduce neuroinflammatory and involve in attenuation of JNK3/PI3K/AKT pathway in the hippocampus.

Objective To explore the factors related to the severity of disease symptoms in patients with acute leukemia (AL). Methods 198 AL patients with symptoms of disease (anemia, bleeding, infection, fever, etc.) from September 2013 to July 2016, were evaluated by the questionnaires of self-rating anxiety scale (SAS), self-rating depression scale (SDS), eysenck personality questionnaire (EPQA), Toronto alexithymia scale (TAS), family environment scale (FES), self-rating scale of illness conception and health seeking behavior (ICHSB). The results were compared with 198 healthy volunteers. Results The scores of SDS, SAS, factorⅠin FES, factor Ⅲ in FES, factor Ⅳ in FES, nervous and the total scores of EPQA, factor Ⅱ in TAS, factor Ⅱ in ICHSB were significantly higher in AL patients than those in healthy subjects [(41.09 ±6.85) scores vs. (36.74±6.99) scores, t=2.150, P=0.031; (38.64±7.51) scores vs. (31.79±7.57) scores, t= 3.327,P=0.001;(2.38±1.54) scores vs. (5.18±1.33) scores, t=3.319, P=0.001;(3.31±1.82) scores vs. (2.23±1.99) scores, t= 3.325, P= 0.001; (2.41±1.62) scores vs. (5.75±1.51) scores, t= 3.332, P= 0.001; (14.14±5.37) scores vs. (11.01±5.51) scores, t= 5.179, P= 0.000; (42.97±7.10) scores vs. (40.41±6.51) scores, t= 2.930, P=0.004;(22.97±4.57) scores vs. (21.54±4.13) scores, t=2.926, P=0.004; (16.37±3.89) scores vs. (15.92± 3.93) scores, t= 2.104, P= 0.034]. The difference was statistically significant (P< 0.05). The risk factors of AL were SAS (95 %CI= 1.064-1.210, P= 0.001), factor Ⅲ in FES (95 %CI= 1.104-1.694, P= 0.004), age (95 %CI= 1.027-1.094, P= 0.001), factor Ⅱ in TAS (95 %CI= 1.046-1.352, P= 0.005), besides, education level (95 %CI= 0.708-0.866, P= 0.001) acted as the protective role. Conclusions AL patients tend to the psychological problems such as depression, anxiety. Those will show much severer symptoms as a consequence of lacking of family warmth and concern, low expression of emotion, lacking of organization, low economic capacity, tension, and lacking of the ability to distinguish between emotion and physical feelings.

Objective:To observe the effect of moxibustion on the mRNA and protein expressions of heat-shock protein 70 (HSP70) in gastric cancer-bearing rats. Methods: A total of 40 healthy Sprague-Dawley (SD) rats were adaptively fed for one week. The gastric cancer model was prepared by Walker-256 cancer tissue transplantation. After 7 d, 10 rats were randomly selected to verify the successful modeling, and the remaining 30 rats were divided into a model group, a moxibustion group and an infrared group by the random number table method, with 10 rats in each group. After enrollment, the moxibustion group received suspended moxibustion at Zhongwan (CV 12), Guanyuan (CV 4) and bilateral Zusanli (ST 36), (the first group of acupoints) on the 1st day, and suspended moxibustion at bilateral Pishu (BL 20) and Weishu (BL 21), (the second group of acupoints) on the 2nd day, 20 min each time, once a day. Moxibustion was alternately performed every other day at the two groups of acupoints for 21 d. From the day of enrollment, rats in the infrared group were irradiated with the infrared radiation at the stomach area on the 1st day, and at the T12-T13 interspinous region on the 2nd day, 20 min each time, once a day, and the two locations were alternately irradiated every other day for 21 d. During the treatment, rats in the model group were intervened by grasping and fixation without treatment. At the end of the treatment, blood was collected from the inner eye orbit, and the HSP70 expression in peripheral blood was determined by enzyme linked immunosorbent assay (ELISA). Rats were sacrificed, the tumor volume and growth inhibition rate were measured. The position and changes of HSP70 in gastric cancer were observed by streptavidin-perosidase (SP); HSP70 protein expression was determined by ELISA; HSP70 mRNA expression in cancer tissues was determined by reverse transcription-polymerase chain reaction (RT-PCR) assay. Results: In comparison of the model group, the volume growth of the gastric cancer in the moxibustion group was significantly restricted (P＜0.01); the volume growth inhibition rate in the moxibustion group was 37.93%; the HSP70 expression in peripheral blood and the cancer tissues was significantly increased (both P＜0.01); the expression of HSP70 mRNA and HSP70 content in gastric tumor were both obviously increased in the moxibustion group (P＜0.01); and a large amount of HSP70 was released to the outside of cancer cells in the moxibustion group. In comparison of the model group, the volume growth of the gastric cancer in the infrared group was slightly restricted (P＜0.05) with a volume growth inhibition rate of 15.89%; the HSP70 expression in the infrared group was increased significantly in peripheral blood (P＜0.01) and in the gastric cancer tissues (P＜0.05); more HSP70 was released outside of the cancer cells in the infrared group. In comparison of the infrared group, the volume growth of gastric cancer was more restricted in the moxibustion group (P＜0.05), and the HSP70 expression in the gastric cancer tissues was also higher (P＜0.05); more HSP70 was released outside of the cancer cells in the moxibustion group. Conclusion: Moxibustion and infrared treatment inhibit the gastric cancer growth in the gastric cancer-bearing rats, up-regulate the HSP70 expression in gastric cancer tissues, and promote the production and extracellular release of HSP70, and the effect of moxibustion is more obvious.

OBJECTIVETo observe the changes in expression of microRNA-203 and P63 in human epidermal stem cells and KCs, and to investigate their effects and significance in the epidermal proliferation and differentiation.

METHODS(1) Five normal foreskin tissue specimens were collected from 5 patients by circumcision in Department of Urinary Surgery of the First Affiliated Hospital of Nanchang University from March to June in 2013. Then single cell suspension was obtained by separating epidermis with trypsin digestion method. The cells were divided into quick adherent cells and non-quick adherent cells by type IV collagen differential adherent method. The biological characteristics of cells were observed by inverted phase contrast microscope immediately after isolation and on post culture day (PCD) 3. The expression of CD29, keratin 19, keratin 1, and keratin 10 was identified by immunocytochemical staining. The expression of microRNA-203 and mRNA of P63 was determined by real-time fluorescent quantitative RT-PCR. The protein expression of P63 was determined by Western blotting. Data were processed with t test and Pearson correlation analysis.

RESULTS(1) Immediately after isolation, quick adherent cells were small, round, and dispersed uniformly. On PCD 3, the cells adhered firmly, and they grew in clones. Immediately after isolation, non-quick adherent cells appeared in different shapes and sizes, and dispersed unevenly. On PCD 3, the cells adhered precariously and did not show clonal growth. Quick adherent cells showed positive expression of CD29 and keratin 19, while non-quick adherent cells showed positive expression of keratin 1 and keratin 10. Quick adherent cells were identified as epidermal stem cells, and non-quick adherent cells were identified as KCs. (2)The expression level of microRNA-203 in epidermal stem cells (0.74 ± 0.20) was lower than that in KCs (3.66 ± 0.34, t =16.582, P <0.001). The mRNA expression level of P63 in epidermal stem cells (4. 16 ± 0.28) was higher than that in KCs (2.90 ± 0.39, t =5. 850, P =0.001). The protein expression level of P63 in epidermal stem cells (1.42 ± 0.05) was higher than that in KCs (0.73 ± 0.03, t =26.460, P <0. 001). (3) The expression level of microRNA-203 was in significantly negative correlation with the expression levels of mRNA and protein of P63 (with r values respectively - 0. 94 and -0.98 , P values below 0.05).

CONCLUSIONSThe expression levels of microRNA-203 and P63 in human epidermal stem cells and KCs were significantly different, which might be related to the different characteristics of proliferation and differentiation of the cells.

International clinical trials register is one of the global measures to realize transparency in clinical trials and also one of a powerful measure to improve the quality of clinical trials. Many scholars studying the quality of TCM clinical trials find that they are poor in quality and lack transparency. Furthermore, they find that TCM clinical trial registry has many problems. We must base on the successful experiences of WHO and international clinical trial registry to establish technical specifications for registry of traditional Chinese medicine clinical study of their own. Then, it can effectively improve the overall level of TCM clinical studies. We have suggested some concrete and feasible measures to establish technical specifications for registry of traditional Chinese medicine clinical study of their own based on the problems of TCM clinical trial registry.
