BACKGROUND: Hip tuberculosis was second to that of the spine. A great number of cases were diagnosed hip tuberculosis every year. The early stage of hip tuberculosis is difficult to be diagnosed, and the X-ray images often show no abnormal signs. When there is an abnormal sign on X-ray, the extent of bone destruction is generally more than 50%. Selection of treatment methods for the patients with hip tuberculosis is the important issue in face of every clinician. OBJECTIVE: To review various types of research progress in clinical treatment of hip tuberculosis in recent years, and to provide reference for clinical treatment of hip tuberculosis. METHODS: We retrieved database of PubMed and CNKI for studies concerning clinical treatment of hip tuberculosis published from January 1969 to March 2017. Key words were "tubercular arthritis, hip, total hip replacement, treatment". After removal of repetitive or irrelevant articles, 42 articles were finally included. RESULTS AND CONCLUSION: (1) In the treatment, current emphasis was on mobility with stability at the hip. (2) Adults with advanced arthritis should be informed and discussed the various treatment modalities including the joint replacement. (3) With the development of artificial arthroplasty, total hip replacement was the preferred choice for patients with advanced hip tuberculosis. More and more surgeons were taking up the challenge of putting the total hip arthroplasty in the active stage of the disease.

Polyamides, containing N-methylpyrrole (Py) and N-methyl-imidazole (Im) amino acids, are synthetic oligomers programmed to read the DNA double helix in the minor groove with high affinities and sequence specificities resulting in modulation of gene expression. They are cell permeable, stable and have no cytotoxicity, which provide a promising tool of gene regulation. We describe here recent advances in the field of DNA binding polyamides, including pairing rules, specifities and affinities to DNA, synthesis methods, cellular and nuclear uptake properties, gene regulation and effectiveness in vivo. The potential problems and difficulties in future research are also discussed.

Objective To investigate the expression of non receptor protein tyrosine phosphatase 12 (PTPN12) in hepatocellular carcinoma (HCC) and its adjacent tissues and investigate the relationship between the expression of non receptor protein and prognosis of hepatocellular carcinoma (HCC).Methods The expresson of PTPN12 protein in HCC tissues and adjacent liver tissues was detected by immunohistochemistry.The relationship between the expression of PTPN12 protein and prognosis of primary hepatocellular carcinoma was evaluated by rank correlation and Cox proportional hazards regression model.Results Compared with the adjacent liver tissues,the expression of PTPN12 protein in HCC tissues was significantly lower (55.83％ vs 43.12％,P＜0.005).Further analysis showed that the decreased expression of PTPN12 was closely related with tumor recurrence (x2 =4.346,P=0.015).Single factor analysis showed that the decreased expression of PTPN12 in hepatocellular carcinoma and liver cancer specific survival and recurrence of hepatocellular carcinoma related (x2=5.687,P＜0.001),and multivariate Cox proportional hazards regression model analysis showed that the expression of PTPN12 in patients with liver cancer were independent prognostic factors (x2 =6.687,P＜0.05).Conclusion The expression of PTPN12 protein was down or absent in human hepatocellular carcinoma,and the expression of PTPN12 may be a biomarker for the recurrence and prognosis of HCC patients.

Objects To explore the association of ulcerative colitis (UC) with the imbalance between Th1,Th 2 and Th17 cells in the colonic tissues.Methods A total of 41 UC patients and 52 controls was recruited in the present study.The real-time fluorescent quantitative PCR was applied for detecting the mRNA levels of Thl,Th2 and Th 17 cells-associated transcription factors T-bet,GATA-3 and RORγt and cytokines IFN-γ,IL-4 and IL-17A in the colonic tissues.Simultaneously,the expressions of IFN-γ,IL-4 and IL-17A in the colonic tissues were also examined by an immunohistochemical staining method.Results Compared with the controls,the mRNA expressions of GATA-3,RORγt and IL-17A were more significantly enhanced in UC patients (0.84 ± 0.24 vs.0.69 ± 0.22,P=0.002;0.99 ± 0.29 vs.0.83 ± 0.23,P=0.004;1.59 ± 0.65 vs.1.35 ± 0.43,P=0.035).According to the ＂Truelove and Witts Severity Index＂,those patients were divided into different subgroups.The mRNA expressions of GATA-3,RORγt,and IL-17A were shown to be higher in patients with moderate and severe UC than in those with mild UC (0.90 ± 0.18 vs.0.78 ± 0.16,P=0.030;1.11 ± 0.31 vs.0.87 ± 0.26,P=0.011;1.83 ± 0.64 vs.1.34 ± 0.66,P=0.020).Moreover,the immunohistochemistry results demonstrated that the IL-17A positive cells were positioned mainly in the intestinal epithelial layer and lamina propria.Compared to the controls,the mean integral optic density of IL-17A was significantly increased in the colonic tissues of UC patients (0.25 ± 0.07 vs.0.13 ± 0.03,P＜0.001).The similar results were obtained for IL-17A in patients with moderate and severe UC when compared to those with mild UC (0.31 ± 0.07 vs.0.19 ± 0.06,P＜0.001).In contrast to the controls,the mRNA ratios ofGATA-3/T-bet,RORγt/ T-bet and RORγt/GATA-3 were significantly higher in the tissues of colonic UC patients (1.12 ± 0.30 vs.0.96 ± 0.31,P=0.014;1.33 ± 0.37 vs.1.15 ± 0.33,P=0.015;1.44 ± 0.45 vs.1.20 ± 0.42,P=0.009),and in the patients,the mRNA ratios for GATA-3/T-bet,RORγt/T-bet and RORγt/GATA-3 were significantly higher in the patients with moderate and severe UC than in those with mild UC (1.27 ± 0.35 vs.1.00 ± 0.32,P＜0.001;1.45 ± 0.37 vs.1.19 ± 0.36,P=0.028;1.59 ± 0.43 vs.1.28 ± 0.46,P=0.031).Conclusions These findings suggest that the imbalance between Thl,Th2 and Th17 cells in the colonic tissues may be implicated in UC.

OBJECTIVETo develop a novel single nucleotide polymorphism (SNP)-PCR based method for quantitative detection of chimerism after allogeneic haemopoietic stem cell transplantation (allo-HSCT), and to explore its feasibility, accuracy and superiority.

METHODS18 SNP loci were sereened to identify informative markers for detecting chimerism in each donor/recipient pair before transplantation. Then the chimerism rate of each informative marker was analyzed by real-time quantitative PCR (RQ-PCR). The accuracy and sensitivity were verified by multiple proportion dilution and analogy chimerism compared with quantitative detection of short tandem repeat (STR)-PCR, fluorescence in situ hybridization (FISH) and fusion gene.

RESULTS(1) The average slope of the 17 time amplications of the internal control plasmid was -3.39, the average intercept was 39.97, correlation coefficients were more than 0.995, which was close to the theoretical level. The intra- and interassay variability was 0.50% and 1.1%, respectively, which were both in the allowed ranges. A linear correlation with artificial mixed chimerism is above 0.99 and a sensitivity of 0.01% proved reproducible. (2) At least one informative marker could be found in over 95% of 40 donor/recipient pairs. The results of the chimerisms derived from SNP-PCR were consistent with that from STR-PCR (96.7%), FISH and fusion gene analasis (P > 0.05); the quantitative results of special fusion gene transcripts were negtive in complete chimerism samples, and positive in mixed chimerism samples.

CONCLUSIONSThis new assay which overcome the PCR competition and plateau biases of STR-PCR provides an accurate, reliable and rapid quantitative assessment of mixed chimerism after allo-transplantation. It is highly promising for of clinical application and may take the place of STR-PCR in the conventional chimerisim assessment.

Objective: To observe the effects of sodium dimercaptosulphonate (DMPS) plus Gandou tablet, DMPS and calcium disodium ethylene diaminotetraacetate (EDTA) on improving liver cirrhosis and liver function of hepatolenticular degeneration (HLD) patients. Methods: One hundred and forty-six HLD patients were divided into A, B, C three groups, and treated with DMPS plus Gandou tablet, DMPS and EDTA respectively, the therapeutic course was 8 weeks for three groups. The ultrasonography of liver, electrophoresis of serum protein and excretion of urinary copper were observed. Results: The ultrasonography of liver was improved in all groups, the rate of improvement of group A was 54.0%, B was 44.0% and C was 39.1%. The amounts of serum albumin in group A and B increased (P＜0.01，P＜0.05), and γ-globulin decreased in all groups (P＜0.05). The excretion of urinary copper increased obviously in all groups (P＜0.01), and group A,B increased more than that of group C (P＜0.05). Conclusions: The de-copper therapy could improve liver cirrhosis and liver function. The effect of DMPS plus Gandou tablet was better than that of DMPS and EDTA.

Objectives:To systemically review the safety and efficacy of bioresorbable vascular scaffold (BVS) versus everolimus eluting stent (EES) for percutaneous coronary intervention (PCI). Methods:The database searched includes PubMed, Medline, MEDILINE, EMBASE, Cochrane library, CNKI and Wanfang. Database retrieval time was between database establishment time to October 2017. During the same time, authors accessed the conference summary and related websites to collect published randomized controlled trials of published data. To evaluate the quality of the literature according to the modified Jadad scale and extracted the data. Meta-analysis was performed using Review Manager 5.3 software. Results:Nine trials were included; 6 721 patients were randomized to receive BVS (n=3 670) or EES (n=3 051). Time of follow-up was ranged from 6 to 36 months. Compared with metallic EES, risk of target lesion failure (RR=1.31, 95%CI:1.08-1.58; P=0.005) and in-stent thrombosis (RR=2.89, 95%CI:1.85-4.53; P＜0.0001), ischemia-driven target lesion revascularization (RR=1.44,95%CI:1.12-1.86, P=0.005)、target-vessel myocardial infarction (RR=1.74, 95%CI:1.33-2.27, P＜0.0001) and all myocardial infarction (RR=1.49, 95%CI:1.16-1.91, P=0.002) were all significantly higher in BVS group than in EES group. There were no significant differences in all-cause death (RR=0.87, 95 % CI:0.57-1.33, P=0.520), cardiovascular mortality (RR=0.78, 95%CI:0.54-1.11, P=0.160) and composite endpoints (RR=1.10, 95%CI:0.95-1.27, P=0.210) between the two groups. Conclusions:Compared with metallic EES, the BVS appears to be associated with both lower efficacy and higher thrombotic risk during the observation period.

OBJECTIVETo explore the effects of low-dose oral tadalafil on self-esteem, confidence and sexual relationship in ED patients.

METHODSWe treated 17 ED patients with oral tadalafil at the low dose of 5 mg once daily for 12 weeks, and used the paired t test to compare their scores on The Self-Esteem and Relationship Questionnaire (SEAR) and IIEF-5 and the results of nocturnal penile tumescence (NPT) obtained by nocturnal electrobioimpedance volumetric assessment (NEVA) before and after the medication.

RESULTSThe scores on SEAR and IIEF-5 were significantly increased (P < 0.01) and NPT markedly improved (P < 0.05) after tadalafil treatment as compared with the baseline.

CONCLUSIONLow-dose oral tadalafil once daily can significantly improve the self-esteem, confidence, sexual relationship satisfaction and NPT of ED patients.

OBJECTIVETo investigate the protective effect of high-pressure carbon monoxide for preservation of ex vivo rabbit heart graft in comparison with the conventional HTK cardioplegic solution preservation.

METHODSHeart grafts isolated from 85 New Zealand rabbits were randomly divided into Naive group (n=5), HTK group (n=40) and CO group (n=40). The grafts underwent no preservation procedures in Naive group, preserved at 4 degrees celsius; in HTK cardioplegic solution in HTK group, and preserved at 4 degrees celsius; in a high-pressure tank (PO2: PCO=3200 hPa: 800 hPa) in CO group with Krebs-Henseleit solution perfusion but without cardioplegic solution. After preservation for 2, 4, 6, 8, 10, 14, 18, and 24 h, 5 grafts from the two preservation groups were perfused for 30 min with a modified Langendorff apparatus and examined for left ventricular systolic pressure (LVSP), left ventricular diastolic pressure (LVDP), arrhythmia score (AS), myocardial ultrestructure, and cardiac enzyme profiles.

RESULTSAfter preservation for 6 to 24 h, the cardiac enzyme profiles and systolic and diastolic functions were significantly better in CO group than in HTK group, but these differences were not obvious between the two groups after graft preservation for 2 to 4 h. Significant changes in the myocardial ultrastructures occurred in the isolated hearts after a 24-h preservation in both CO and HTK groups, but the myocardial damages were milder in CO group.

CONCLUSIONPreservation using high-pressure carbon monoxide can better protect isolated rabbit heart graft than the conventional HTK preservation approach especially for prolonged graft preservation.
