This study was aimed to improve the sensitivity of magnetic induction phase shift detection system for cerebral hemorrhage. In the study, a cerebral hemorrhage model with 13 rabbits was established by injection of autologous blood and the cerebral hemorrhage was detected by utilizing magnetic induction phase shift spectroscopy (MIPSS) detection method under the feature band. Sixty five groups of phase shift spectroscopy data were obtained. According to the characteristics of cerebral hemorrhage phase shift spectroscopy under the feature hand, an effective method, B-F distribution, to diagnose the severity of cerebral hemorrhage was designed. The results showed that using MIPSS detection method under feature band, the phase shift obviously growed with increase of injection volume of autologous blood, and the phase shift induced by a 3-mL injection reached -7.750 3 degrees ± 1.420 4 degrees. B-F distribution could effectively diagnose the severity of cerebral hemorrhage. It can be concluded that the sensitivity of the cerebral hemorrhage magnetic induction detection system is improved by one order of magnitude with the MIPSS detection method under the feature band.

OBJECTIVETo investigate the efficacy of the procedure for prolapse and hemorrhoids (PPH) combined with external hemorrhoids excision in the treatment of III or IV mixed hemorrhoids.
METHODSOne hundred and twelve patients with III or IV mixed hemorrhoids admitted for surgical treatment were randomly divided into three groups: PPH 1 group (34 cases), PPH2 group (36 cases), and Milligan-Morgan group (42 cases). PPH1 group received the standard PPH operation, PPH2 received PPH and external hemorrhoids excision, and Milligan-Morgan group received Milligan-Morgan hemorrhoidectomy. Postoperative 24 h-pain index, pain index when defecating, bleeding, anal discomfort feeling , wound edema, the ability of controlling feces, operating time, hospitalization time and charges were recorded. The change of anal dynamics was detected by anorectal manometry. All the patients were followed-up for 0.5-1 year.
RESULTSThere were no significant differences among the three groups in bleeding, anal discomfort feeling, the ability of controlling feces (P>0.05). The postoperative 24 h-pain index of PPH1 group was lower than those of the other two groups (P<0.05). PPH1 group and PPH2 group were better than Milligan-Morgan group in pain index when defecating, wound edema, operating time, and hospitalization time (P<0.05). Milligan-Morgan group was better than the other two groups in postoperative urinary retention and hospital charges (P<0.05). The change of anal duct pressure of Milligan-Morgan group was less than those of the other two groups (P<0.05). Within 0.5-1.0 year follow-up, 3 patients got thrombosed external hemorrhoid in PPH1 group, 2 patients recurred and 1 patient got thrombosed external hemorrhoid in Milligan-Morgan group, no recurred patients in PPH2 group.
CONCLUSIONPPH combined with external hemorrhoid excision is a safe and effective treatment for mixed hemorrhoids, which is suitable for mixed hemorrhoids with severe external hemorrhoids.

BACKGROUNDSepsis is a leading cause of death in the intensive care units. The late inflammatory cytokine, high-mobility group box 1 (HMGB1), plays a critical role in sepsis. In the present study, we investigated the association between the serum HMGB1 levels and the severity of organ injury in the lipopolysaccharide-induced sepsis in rats.
METHODSTo produce an animal model of sepsis with different degree of organ injury, animals were treated with three different doses of lipopolysaccharide (4, 8 and 16 mg/kg), and the animals in control group were treated with the same volume of the vehicle (saline). The levels of serum HMGB1 were measured at 0, 2, 4, 8, 16, 24, 32 and 48 hours after lipopolysaccharide (LPS) or vehicle injection, meanwhile the biochemical and histopathological indicators for the severity of organ injury were assessed.
RESULTSThe level of HMGB1 had a positive, high correlation with the abnormal changes of serum cardiac troponin I, alanine aminotransferase, aspartate aminotransferase, creatinine and blood urea nitrogen, as well as the pathologic scores of heart, lung, liver and kidney.
CONCLUSIONSThe level of serum HMGB1 is highly correlated with the severity of sepsis in rats, suggesting that HMGB1 could serve as a valuable adjunct in the diagnosis and management of sepsis.

BACKGROUNDOff-label application of drug-eluting stents (DES) during percutaneous coronary intervention (PCI) was not uncommon in daily practice, however DES in treating Chinese patients with complex lesion subset was under-investigated. The primary objective of the FIREMAN registry was to evaluate the long term efficacy and safety of the Firebird sirolimus-eluting stent (SES) in treating patients with complex coronary lesions. Here we report the mid-term of one-year clinical outcomes and eight-month angiographic follow-up results of FIREMAN registry.
METHODSThe FIREMAN registry was a prospective multi-center registry, which included 1029 consecutive patients undergoing PCI with Firebird SES implantation between September 2006 and July 2007 in 45 centers in China. The clinical follow-up was designed to be performed at 1, 6, 12, 18, 24, 30 and 36 months post index procedure, and non-mandatory angiographic follow-up at 8 months was planned. One hundred percent site monitoring was conducted.
RESULTSLong lesions (59.2%), multi-vessel disease (50.4%), and small vessel disease (31.6%) were mostly found in angiography. Major adverse cardiac events (MACE) occurred in 51 (5.1%) patients at 1 year clinical follow-up, including cardiac mortality in 6 (0.6%), non-fatal myocardial infarction in 11 (1.1%), and target lesion revascularization in 36 (3.5%) of the patients. Definite and probable stent thrombosis (ST) by Academic Research Consortium (ARC) definition occurred in 12 (1.36%) patients at one-year clinical follow-up. The 8-month binary restenosis rate was 5.7% in-segment and 4.3% in-stent, respectively. Late lumen loss was (0.21 ± 0.40) mm in-segment and (0.23 ± 0.36) mm in-stent, respectively. Furthermore, Cox regression analysis revealed that diabetes, small vessel diameter, and chronic total occlusion were independent predictors of ST.
CONCLUSIONSThe results showed that the Firebird SES was effective and safe in treating Chinese patients with complex coronary lesions and occurrence of ST rate at one-year clinical follow-up was acceptable, however further long-term follow-up was still necessary. (NCT00552656)
