OBJECTIVETo evaluate the efficacy and safety of entecavir (ETV) maleate versus ETV in Chinese patients with hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB).
METHODSThis was a randomized, double-blind, double-dummy, controlled, multicenter study. Patients were randomly assigned to receive 48 weeks of treatment with 0.5 mg/day ETV (group A; n = 26) or 0.5 mg/day ETV maleate (n = 31). Hepatitis B virus (HBV) DNA levels were measured at weeks 12, 24, and 48 by the Roche Cobas Ampliprep/Taqman PCR assay. Adverse events (AE) were recorded.
RESULTSBaseline characteristics were similar between the two groups. At weeks 12, 24, and 48, the mean HBV DNA level had similarly decreased from baseline in both groups (A: by 4.24, 4.61 and 4.88 log10 IU/mL vs. B: 4.01, 4.50 and 4.99 log10 IU/mL, respectively; all P more than 0.05). Patients who achieved undetectable levels of serum HBV DNA (less than 20 IU/mL) at week 48 were similar in the two groups (A: 69.23% vs. B: 80.65%; P more than 0.05). Both groups achieved similar normalization of ALT at week 48 (A: 96.00% vs. B: 83.87%; P more than 0.05). The overall AE incidence was similar for the two groups (A: 22.22% vs. B: 9.38%; P more than 0.05).
CONCLUSIONEntecavir maleate and entecavir showed similar efficacy and safety in patients with HBeAg-negative CHB.

OBJECTIVETo analyze the correlation of Chinese medicine syndrome evolvement and cardiovascular: events in patients with stable coronary heart disease (CHD).
METHODSThis prospective cohort study investigated and: collected the clinical information of patients with stable CHD and observed the syndrome type at the baseline and 6-month at follow-up, as well as the cardiovascular events during the 6-month and 12-month follow-up. The patients were divided into the event group and the non-event group. The interaction and the impact of syndrome evolvement on cardiovascular events were examined through multifactor dimensionality reduction (MDR) analysis and the results were verified by Chi-square test.
RESULTSTotally 1,333 of 1,503 stable CHD patients enrolled met the inclusion criteria: of MDR analysis. Among them, 959 (71.9%) cases were males and 374 (28.1%) cases were females. Thirty seven cases had cardiovascular events during 6 to 12 months after the study began. The results of the MDR analysis and verification using Chi-square test showed that the development of cardiovascular events was positively correlated with interaction between blood stasis and toxic syndrome at the baseline, blood stasis at the baseline and qi deficiency at the 6-month follow-up, toxic syndrome at the baseline and qi deficiency at the 6-month follow-up, toxic syndrome at the base line and blood stasis at the 6-month follow-up, qi deficiency and blood stasis at the 6-month follow-up (P<0.05 for all).
CONCLUSIONSBlood stasis, toxic syndrome and qi deficiency are important factors of stable CHD. There: are positive correlation between cardiovascular events and syndrome evolution from blood stasis to qi deficiency, from toxic syndrome to qi deficiency and from toxic syndrome to blood stasis, indicating the pathogenesis of toxin consuming qi, toxin leading to blood-stasis in stable CHD patients prone to recurrent cardiovascular events.

OBJECTIVETo describe observation of security and availability of covering left subclavian artery during thoracic endovascular aortic repair (TEVAR) in follow-up.
METHODSFrom December 2007 to December 2008, 111 consecutive patients received stent grafts to treat lesions involving thoracic aorta. According to the covering of left subclavian artery, four groups including total covering (TC), less-than 50% covering (LTC), more-than 50% covering (MTC) and non-covering (NC) were formed. Difference of blood pressure between two upper extremities was required before TEVAR and 1st, 3rd, 5th, 30th day after TEVAR. Patients were evaluated postoperatively and at follow-up for stroke as well as symptoms of paraplegia, hemiparalysis or left upper extremity claudication.
RESULTSFifty-five (49.6%), 18 (16.2%), 7 (6.3%) and 31 (27.9%) cases were divided into TC, LTC, MTC and NC groups, respectively. Difference of blood pressure between TC and the 3 latter groups were significantly different (P<0.01). Complications appeared as followed during one week after TEVAR: 13 patients in dizziness, among which 5 patients suffered from amaurosis and spotted vision, and 7 patients in left upper extremity claudication. No stroke, paraplegia or hemiparalysis in TC. Thoracic aortic lesions were successfully excluded in all patients.
CONCLUSIONSIntentional coverage of left subclavian artery to obtain an adequate proximal landing zone during TEVAR is safe and well-tolerated. But it may be managed expectantly with some exceptions for further lasting efficacy.

Objective To introduce an optimized practical method of making and detecting pipettes for microinjection.Methods Transfer pipette was made from hard glass capillary. We softened the hard glass capillary by rotating it in a spirit-lamp flame,then moved out from the flame and quickly pulled it into two transfer pipettes.After broken by a grinding wheel,the tip of the pipette was fire-polished by quickly touching the flame to make a fine opening.A hard glass capillary (1.0 mm,ouside diametre)was pulled into two holding pipettes by pipette Puller.The pipette shoulder was broken at desired position with a grinding wheel,then the fine pipette tip opening was heated by a microforge and shrinked into a diameter -15 μm.Injection pipette could be made directly from a capillary with filament by Puller.The solution loaded injection pipette and holding pipette were assembled into the micromanipulator and could be checked before use.We transfered both pipettes into the zygotes media drop,touched the holding pipette with the tip of the injection pipette to make a "suitable"opening.Then we switched injection pipette to the mineral oil and applied injection pressure through the injector to check whether the solution could come out of the tip smoothly and at a proper speed.It could be further verified by pronucleus microinjection of zygotes.Results The results showed that the method introduced in this paper could produce suitable pipettes for zygote microinjection.In particular,the method of detecting the opening of the injection pipette was helpful for achieving high efficiency of zygote microinjection.Conclusion The method introduced here to make and detect pipettes for microinjection is very helpful for establishing a standard microinjection manipulation procedure and improving the efficiency of zygote microinjection.
