BACKGROUND AND PURPOSE: Five single-nucleotide polymorphisms (SNPs) (rs4379368, rs10504861, rs10915437, rs12134493 and rs13208321) were recently identified in a Western population with migraine. These migraine-associated SNPs have not been evaluated in a Han Chinese population. This study investigated the associations of specific SNPs with migraine in a Han population. METHODS: This was a case-control study of Han Chinese residing in Fujian Province. Polymerase chain reaction—restriction-fragment-length polymorphism analysis and direct sequencing were used to characterize the relationships of SNPs in a control group of 200 subjects and in a migraine group of 201 patients. RESULTS: The frequencies of the five SNPs did not differ between patients with migraine and healthy non migraine controls. However, subgroup analysis indicated certain SNPs were more strongly associated with migraine with aura or migraine without aura than with controls. The CT genotype of rs4379368 was more common in migraine patients with aura (75%) than in migraine patients without aura (47.9%) and controls (48.5%) (p<0.05), and the TT genotype of rs10504861 was more common in migraine patients with aura than in controls (8.3% vs. 0.5%) (p<0.05). Meanwhile, the CC genotype of rs12134493 was less common in migraine patients without aura than in controls (80.6% vs. 88%) (p<0.05). CONCLUSIONS: Our findings suggest that the rs4379368 and rs10504861 SNPs are markers for susceptibility to migraine with aura and that rs12134493 is a marker for the risk of migraine without aura in this Han population. Future studies should further explore if these associations vary by ethnicity.

OBJECTIVETo investigate the inhibitory effect on HBV replication of antisense locked nucleic acid (LNA) targeting to both S and C genes in HBV transgenic mice.

METHODSThirty HBV transgenic mice were randomly divided into five groups (n = 6): glucose control group were treated with 5% glucose solution, liposome control group were treated with liposome alone, S group were treated with LNA targeting to S gene, C group were treated with LNA targeting to C gene, and dual-target group were treated with LNA targeting to both S and C genes. Antisense LNA was injected into mice via the tail vein. Serum HBsAg was quantified by TRFIA. Serum HBV DNA was quantified by real-time PCR. The expression of HBV C-mRNA in the liver was detected by RT-PCR. The expression of HBsAg and HBcAg in the liver was detected by immunohistochemistry. Serum ALB, ALT, BUN and CR were measured using an automatic biochemical analyzer. The effects of antisense LNA on mouse organs were investigated by HE staining.

RESULTS5 days after LNA injection, serum HBsAg levels in the dual-target group were reduced by 72.8%, and serum HBV DNA levels were decreased by 52.9%. These values were significantly higher than those in the control groups (all P < 0.05). No significant differences were noted in serum ALB, ALT, BUN and CR between the experiment groups and the control groups (all P > 0.05). The expression levels of HBsAg and HBcAg in the liver of dual-target group were significantly lower than those in the control groups. No significant histopathological abnormality was found in liver and kidney tissues in all groups.

CONCLUSIONAntisense LNA targeting to both S and C genes can significantly inhibit HBV replication in transgenic mice.

Objective: This study compared the outcomes of laparotomic radical hysterectomy (LRH) and minimally invasive radical hysterectomy (MISRH) in patients with early-stage cervical cancer. Methods: The clinical data of patients with early-stage cervical cancer who underwent LRH or MISRH (laparoscopic/robotic) at Chang Gung Memorial Hospital, Linkou Branch, from 2002 to 2017 were retrospectively reviewed. The surgical safety (operation time, blood loss, blood transfusion rate, length of postoperative stay, and perioperative complications), overall survival (OS), disease-free survival (DFS), and recurrence pattern were analyzed. Propensity score matching (PSM) at a 3:1 ratio was performed to balance prognostic variables. Results: Of the 760 patients (entire cohort), 614 underwent LRH and 146 underwent MISRH.After PSM, 394 and 140 patients were included in the LRH and MISRH groups, respectively.The 5-year OS rate was significantly lower in the MISRH group than in the LRH group (85.6% vs. 93.2%, p=0.043), and the 5-year DFS rate (p=0.21) did not differ significantly. After PSM, the 5-year OS rates did not differ significantly between the MISRH and LRH groups (87.1% vs. 92.1%, p=0.393). The MISRH group had a significantly shorter operation time (p<0.001), lower intraoperative blood loss (p<0.001), lower blood transfusion rate (p<0.001), and shorter postoperative stay (p<0.001) but a significantly higher rate of intraoperative bladder injury (p<0.001) than the LRH group. Conclusion After PSM, MISRH is associated with nonsignificantly lower OS but a significantly higher risk of intraoperative urological complications than LRH.

OBJECTIVETo study the "hot spot" of BRCA1/2 gene mutations in Chinese mainland breast cancer population.

METHODSThe known BRCA1/2 gene mutations in author's previous studies were reanalyzed by denaturing high performance liquid chromatography and DNA sequencing method in 177 patients with early onset breast cancer or affected relatives and 426 sporadic breast cancer patients from four breast cancer centers in China.

RESULTSThree cases were found with BRCA1 5589del8 mutation out of 247 hereditary-predisposing breast cancer patients (70 patients in previous study and 177 patients in current study) and 2 cases with BRCA1 5589del8 mutation out of 426 sporadic breast cancer patients. They had similar even same haplotype.

CONCLUSIONBRCA1 5589del8 mutation is likely to be the "founder mutation" in Chinese population, but it should be confirmed by further studies.

BACKGROUNDIntraoperative magnetic resonance imaging (iMRI) dates back to the 1990s and has been successfully applied in neurosurgery but they were low-field iMRI (< 1.0T). This paper reports the clinical experience with a 3T iMRI-integrated neurosurgical suite in Huashan Hospital, Shanghai, China.

METHODSFrom September 2010 through March 2012, 373 consecutive patients underwent neurological surgery under guidance with 3T iMRI. A retrospective analysis was conducted regarding clinical efficiency.

RESULTSAll surgery in the 373 patients was safe. The ratio of gross total resection for cerebral gliomas (n = 161) was increased from 55.90% to 87.58%. The ratio of benefit in extent of resection was 39.13%. One hundred and fifty eight of the 161 glioma patients accomplished follow-up at 3 months postoperatively. Twenty of 161 patients (12.42%) suffered from early motor deficit after surgery. Late motor deficit was however observed in five of 158 patients (3.16%). Twenty-one of 161 patients (13.04%) had early speech deficit and late speech deficit was only observed in six of 158 patients (3.80%). The ratio of gross total resection for pituitary adenomas (n = 49) was increased from 77.55% to 85.71%. The ratio of benefit in extent of resection was 10.2%. There were no iMRI-related adverse events even for patients who underwent awake craniotomy.

CONCLUSIONThe 3T iMRI integrated neurosurgical suite provides high-quality intraoperative structural and functional imaging for real-time tumor resection control and accurate functional preservation, resulting in an improvement in maximal safe brain surgery.

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)
