Objective To explore the relationship between the plasma level of carbon monoxide and the hyperdynamic circulation of cirrhotic rats. Methods S.D. rats were divided into cirrhotic ( n =10) and control ( n =10) groups. Liver cirrhosis was induced by percutaneous administration of carbon tetrachloride. Mean arterial pressure (MAP, kPa),heart rate (HR,beat/min) and portal pressure (PP,cm H 2O) were measured by indwelling catheters. Plasma CO was measured by Chalmers method, and plasma NO 2/NO 3 was determined by the reduction of cadmium column. Heme oxygenase (HO) activity in splanchnic organs from cirrhotic rats and controls was also determined. Results Typical features of cirrhosis were histologically observed in carbon tetrachloride treated animals. The cirrhotic group presented a significant increase in plasma CO [( 18.69 ? 1.86 )?mol/L vs. ( 10.27 ? 1.21 )?mol/L, P

Objective: To explore the significance of Th17 in hepatocellular carcinoma, expecially with HBV infection.Methods:Cytometric bead array(CBA) was employed to detect 5 cytokines(IL-2,IL-4,IL-6,IFN-γ,IL-17A)from 39 tumor and non-tumor tissues of HCC and combined clinical data for comparative statistic analysis.Results:The expression of IL-2,IL-4,IFN-γin liver cancer tissue[(4.61±0.28),(3.37±0.58),(3.08±1.08)pg/ml,respectively] was significant lower than non-cancer tissue [(5.57±0.59),(3.77±0.70),(3.69±1.20)pg/ml,respectively].Otherwise,the expression of IL-6,IL-17A in cancer tissue [(280.09±254.68), (2.66±1.66) pg/ml, respectively] was higher than non-cancer [(6.58 ±1.92), (1.49 ±0.98) pg/ml, respectively].And,whatever cancer or non-cancer tissue,the expression of IL-17A in tissue[(3.45±1.86)pg/ml] with high HBV load (>1 000 U/ml) was significant higher than tissue with low HBV load[(1.97±1.16)pg/ml].Conclusion: IL-17A was highly expressed in HCC,and IL-2,IL-4,IFN-γmay inhibit its expression,and IL-6 may promote it.Hepatitis B virus infection may promote Th17 expression,thereby reducing patient′s prognosis.

Objective The study was to explore the effect of the Wechat combined with discharge supervision on rehabilitation of empty-nesters with total knee arthroplasty (TKA).Methods 100 emptynesters who were treated with unilateral TKA from September 2013 to August 2014 were selected and randomly divided into the experimental group and the control group with 50 patients in each group.All patients received the same orthopaedic hospital routine therapy and nursing,hospital rehabilitation exercise,guidance,family visits and conventional outpatient care.Besides the above treatment,the experimental group received nursing instruction after discharge by professional nurses through Wechat platform,which included functional exercise guidance,psychological guidance and daily activities instructions.The hospital for special surgery(HSS) knee score and the modified Barthel Index (MBI) score were assessed on the 14th day,the third month and the sixth month after surgery.Results HSS knee score and MBI score had no statistically significant difference between the experimental group and the control group on the 14 th day after surgery; HSS knee score and MBI score of the experimental group on the third month and the sixth month after surgery were significantly higher than those of the con-trol grou,t value was 9.24,11.07 and 21.92,14.14.Conclusions Wechat combined with discharge super-vision can effectively improve the rehabilitation effect of empty-nesters after total knee arthroplasty.

AIM:To study the effcts of caspase recruitment domain membrane-associated guanylate kinase protein 3 (CARMA3) knockdown on the growth, migration and invasion of human colonic carcinoma HCT116 cells and to analyze the mechanism.METHODS:A colonic carcinoma cell line with CARMA3 over-expression was selected.The CARMA3 gene in the HCT116 cells was knocked down by lentivirus technique.After screening by puromycin, the stably-transfected HCT116-shCARMA3 cell line was constructed.CARMA3 expression at mRNA and protein levels was detected by real-time PCR and Western blot,respectively.The cell proliferation was analyzed by WST-1 assay and RTCA S16 system.The colony formation ability was measured by colony-forming assay.The cell cycle was analyzed by flow cytometry.The cell morphological changes were observed under microscope.The abilities of migration and invasion in vitro were observed by wound healing assay and Transwell assay.The changes of related molecules were determined by Western blot to explore the mechanism.RESULTS:The expression of CARMA3 at mRNA and protein levels in the HCT116 cells was the highest in the 4 colonic carcinoma cell lines.HCT116-shCARMA3 cells with stably-silenced CARMA3 gene were successfully established.Among them, HCT116-shCARMA3-93 cells showed the greatest inhibition of CARMA3 at mRNA and protein levels.Therefore,HCT116-shCARMA3-93 cells were chosen as the cell model.Compared with control group, the morphological changes of the HCT116-shCARMA3-93 cells had epithelial-mesenchymal transition (EMT) reversion.The abilities of proliferation, colony formation, migration and invasion in the HCT116-shCARMA3-93 cells were obviously suppressed (P<0.01).G0 /G1 phase proportion was increased and S phase proportion was correspondingly decreased (P<0.05).Bcl10 and NF-κB were down-regulated, and mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT-1)showed no change.Cyclin D1 was decreased obviously and cyclin A declined slightly.Metastasis-related mar-kers matrix metalloproteinase (MMP)-2 and MMP-9 were reduced,MMP-7 remained unchanged, while tissue inhibitor of metalloproteinase(TIMP)-1 and TIMP-2 were up-regulated.Furthermore, EMT-associated molecule E-cadherin was increased, while N-cadherin, Snail, Slug and Twist were decreased to some extent.CONCLUSION:CARMA3 has an impact on the growth,migration and invasion of colonic carcinoma cell line, which is possibly related to NF-κB signaling pathway to change cell cycle and metastasis-related markers and to regulate EMT.

Objective To analyze the influence of peptidimer-c on the gene expression profiling of K562 cells and investigate the mechanism of peptidimer-c inducing the apoptosis and inhibiting proliferation of K562cells.Methods Trypan blue staining technique was performed for counting the number of living K562 cells treated with peptidimer-c.The ultrastructure changes of K562 cells treated with peptidimer-c was observed under transmission electron microscope.The Human U133 Plus 3.0 gene chips were used to detect the differentially expressed genes of K562 cells treated with peptidimer-c.Reverse transcription PCR was conducted to confirm some genes identified by gene chips.Results Peptidimer-c could induce the apoptosis and inhibit the proliferation of K562 cells.Peptidimer-c caused widely changes of the gene expression profiles of K562 cells.The chip data suggested that there were 529 differentially expressed genes,of which 455 genes were up-regulated and 74 genes were down-regulated.The relevant apoptotic genes were down-regulated markedly,including JUN,AXUD1,TNFRSF10B,etc.Fifteen of the differentially expressed genes were detected by RT-PCR,which was consistent with the chip data.Conclusion Peptidimer-c may induce aooptosis of K562 cells by activating the TNF/TNFR family and the JUN family.

Objective To improve the knowledge of primary gout in children. Methods Clinical data of a 12-year-old girl with primary gout was collected. Analysis of UMOD gene, REN gene and HNF-1βgene was performed using PCR and di-rect sequencing. Results The girl was admitted for 1-month history of left hallux pain accompanied with elevations of serum uric acid concentration and serum creatinine concentration. Several examinations showed serum uric acid/creatinine ratio was greater than 2.5. The fractional excretion of uric acid was 3.4%-6.6%. The X-ray showed that the proximal phalanxes of halluces were erosion. The diagnosis of renal biopsy was ischemic renal injury and chronic tubulointerstitial nephropathy. Blood uric acid concentrations of parents were normal, and the family history of gout was negative. Two single nucleotide polymorphisms (c.264C>T heterozygous and c.866-71 G>A heterozygous) in UMOD gene, 1 single nucleotide polymorphism (c.373+44C>G heterozygous) in REN gene, and 2 single nucleotide polymorphisms (c.100-50-49ins TCTG heterozygous and c.781-22T>C homozygous) in HNF-1βgene were detected. No pathological mutation was detected in these 3 genes. Conclusions This child is highly suspected to have primary gout caused by familial juvenile hyperuricemic nephropathy.

OBJECTIVETo observe the efficacy and safety of acupuncture therapy on moderate and severe allergic rhinitis via the comparison evaluation of western medicine.

METHODSSixty cases of moderate and severe allergic rhinitis were divided into an acupuncture group (30 cases) and a western medicine group (30 cases). In the acupuncture group, the main acupoints included Yingxiang (LI 20), Shangxing (GV 23), Fengchi (GB 20), Quchi (LI 11), Xuehai (SP 10), Feishu (BL 13), Geshu (BL 17), Pishu (BL 20), etc. The supplementary points were selected according to syndrome differentiation. In the western medicine group, budesonide nasal spray and cetirizine tablets were prescribed. All the cases were treated for 8 weeks in the two groups. Separately, before treatment, in 4 weeks and 8 weeks of treatment, the scores of clinical symptoms and physical signs were observed and the clinical efficacy and safety were compared between the two groups.

RESULTSIn 4 weeks and 8 weeks of treatment, the scores of symptoms such as sneezing, nasal discharge, nasal obstruction, nasal itching, eye itching and turbinate hypertrophy, the score of physical signs and total score were all reduced apparently as compared with those before treatment (all P<0. 05). The differences were not significant between the acupuncture group and the western medicine group (all P>0. 05). The total effective rates were 90. 0% (27/30) and 93. 4% (28/30) in the acupuncture group after 4 and 8 weeks of treatment, and were 76. 6% (23/30) and 80. 0% (24/30) in the western medicine group separately, without significant difference in comparison (all P>0. 05).

CONCLUSIONAcupuncture achieves the similar efficacy on moderate and severe allergic rhinitis as western medicine. It is the safe therapy and has no apparent adverse reactions.
