Primary prophylaxis of variceal haemorrhage with non-selective beta blockers (NSBB) or variceal band ligation (VBL) is now standard of care in patients with cirrhosis with portal hypertension. NSBB, and particularly carvedilol, may be associated with improved survival.

To assess mortality in a cohort of patients previously randomised to either carvedilol or VBL.

We retrospectively analysed 152 patients recruited to a multi-centre randomised controlled trial between 7 April 2000 and 24 June 2006 designed to assess the efficacy of VBL versus carvedilol in preventing first variceal bleed. We used electronic records to undertake long-term follow-up (up to 20years) with the primary outcome of all-cause mortality and secondary end points of liver-related mortality and decompensation events (ascites, encephalopathy, variceal bleeding).

We included 152 patients in analysis with baseline characteristics well matched between the carvedilol (n=77) and VBL (n=75) groups. In the intention-to-treat analysis, carvedilol offered a significant survival advantage with median survival of 7.8years compared to 4.2years in the VBL group (P=0.03). This survival benefit was maintained in per-protocol analysis when patients who crossed between treatment arms were excluded (P=0.02). Transplant-free survival, liver-related mortality and decompensation events were similar in both groups.

These data suggest that carvedilol offers a significant survival benefit for patients with cirrhosis and portal hypertension. The difference in all-cause and liver-related mortality suggests that this survival benefit may not be entirely liver-related. Prospective, studies are required to confirm these important findings.

MicroRNAs (miRNAs) can participate in a variety of inflammatory lesions and modulate bone metabolism through the posttranscriptional regulation of target genes. In recent years, studies have confirmed that some miRNAs play significant roles in the development of inflammatory alveolar bone defects. Therefore, we reviewed the correlation between miRNAs and inflammatory alveolar bone defects and elucidated the underlying mechanisms to provide new ideas for the prevention and treatment of inflammatory alveolar bone defects.

Cepharanthine (CEP), a compound extracted from the vine Stephania cephalantha, is commonly prescribed to treat alopecia areata; however, the scientific evidence for its efficacy is limited.

To investigate the effect of CEP and its structural analogues on human hair growth in vitro.

The effects of CEP and three of its structural analogues on the proliferation of human dermal papilla cells (hDPCs) and human outer root sheath cells (hORSCs) were investigated. Their effects on vascular endothelial growth factor (VEGF) expression were also assessed by real-time PCR. Activation of pathways leading to VEGF expression, such as intracellular Ca

mobilization and hypoxia-inducible factor (HIF) expression, was also characterized.

CEP and two of its structural analogues significantly stimulated the growth of hDPCs but not hORSCs. Moreover, CEP and all three structural analogues significantly induced the expression of VEGF in hDPCs. CEP increased the intracellular Ca

concentration in hDPCs. CEP also increased the expression of HIF-1α and HIF-2α and induced the expression of HIF-responsive genes in hDPCs, even under normoxia.

These results suggest that CEP and its structural analogues have the potential to restore hair growth by promoting the proliferation of hDPCs and increasing their expression of VEGF.

We aimed to compare the acute differences in left ventricular (LV) function and mechanical synchrony during nonselective His bundle pacing (ns-HBP) versus selective His bundle pacing (s-HBP) using strain echocardiography.

Consecutive patients with permanent His bundle pacing, in whom it was possible to obtain both s-HBP and ns-HBP, were studied in two centers. In each patient, echocardiography was performed sequentially during s-HBP and ns-HBP. Speckle-tracking echocardiography parameters were analyzed Global longitudinal strain (GLS), the time delay between peak systolic strain in the basal septaland basal lateral segments (BS-BL delay), peak strain dispersion (PSD) and strain delay index. Right ventricle function was assessed using tricuspid annular plane systolic excursion (TAPSE) and tissue Doppler velocity of the lateral tricuspid annulus (S'). A total of 69 patients (age 75.6 ± 10.5 years; males 75%) were enrolled. There were no differences in LV ejection fraction and GLS between s-HBP and ns-HBP modes 59% versus 60%, and -15.6% versus -15.7%, respectively; as well as no difference in BS-BL delay and strain delay index. The PSD value was higher in the ns-HBP group than in the s-HBP group with the most pronounced difference in the basal LV segments. No differences in right ventricular function parameters (TAPSE and S') were found.

The ns-HBP and s-HBP modes seem comparable regarding ventricular function. The dyssynchrony parameters were significantly higher during ns-HBP, however, the difference seems modest and clarification of its impact on LV function requires a larger long-term study.
