Objective To investigate whether emergency percutaneous coronary intervention(PCI) could influence the BNP level in patients with ST-segment elevation myocardial infarction(STEMI).Methods We enrolled 193 patients who were admitted with STEMI.The BNP levels were measured at admission.All patients underwent routine clinical laboratory tests in the first day of hospitalization.Ninety-two patients underwent emergency PCI and the other 101 patients received conservative medicine treatment.The patients who had emergency PCI were divided into two subgroups according to the time between symptom onset and PCI started(ictus time 0-3 h,n=42;ictus time 3-6 h,n=50) for analysis.Results BNP levels were significantly lower in patients undergoing PCI when compared with conservative medicine treatment(261.0?410.9 ng/L vs 921.5?1126.7 ng/L,P

Background Corneal chemical burns,especially hazards of alkali burn become increasingly prominent.Clinically,anti-inflammatory,immuno-suppression,corneal transplantation are the common treating method for corneal alkali burn.But the research of tissue repair under the microenvironment of corneal alkali burn is necessary.Objective The aim of this study was to investigate the therapeutic effect of deproteinised calf serum eye gel on the corneal alkali burn.Methods Alkali burn model of cornea was established on the right eyes by putting the filter paper with 0.5 mol/L NaOH on the center cornea for 1 minute in 24 white rabbits.The model rabbits were divided randomly into 4 groups.Normal saline solution,deproteinised calf serum eye gel,blank matrix gel or recombinant bovine basic fibroblast growth factor(rb-bFGF)eye-gel was topically administered 4 times per day for 14days in the 4 groups,respectively.The inflammatory reaction was examined under the slit lamp and scored based on Ando' s criteria.Corneal fluorescine staining was performed to calculate the corneal ulcer area and scored based on Trousdale' s criteria.Histopathological examination of corneas was performed on the fourtcenth day after experiment.The use of the experiment animals complied with ARVO Statement.Results Corneal edema and opacification were seen in the model eyes with the modeling successful rate 100％.On the seventh day after experiment,the severe ulcer of cornea and hypopyon appeared in the normal saline solution group.Corneal epithelium was intact but the intrarocular structure was invisible in the blank matrix gel group.In th(c) rb-bFCF group,corneal new vessels were seen,however,the corneal ulcer completely regrow in the deproteinised calf serum eye gel group.In 3,5,7,10 and 14days after examination,the corneal inflammatory scores were significantly lower in the deproteinised calf serum eye gel group and rb-bFGF group than those of the normal saline solution(P＜0.01).No significant difference was found in the inflammatory score between the deproteinised calf serum eye gel group and rb-bFGF group (P＞0.05) but was significantly lower than the blank gel matrix group (P ＜ 0.05).With respect to the corneal ulcer,the score was decreased in the deproteinised calf serum eye gel group compared with the normal saline solution group and blank gel matrix group (P ＜ 0.05).Howcver,no significant difference was found in the corneal ulcer score between the deproteinised calf serum eye gel group and rb-bFGF group in various time points (P＞ 0.05).Conclusions Deproteinised calf serum eye gel can promote the healing of corneal ulcer and remit the inflammatory response afler corneal alkali burns with a better effectiveness than rb-bFGF.

Objective Aim To investigate the effects of high-burden thrombus on outcomes of emergency percutaneous coronary intervention(PCI)in elderly patients with acute myocardial infarction.Methods Seventy-three elderly patients with ST elevated acute myocardial infarction(STEAMI)within 12 hours from onset received emergency PCI.They were divided into the high-burdern thrombus group(n=26)and the low-burden thrombus group(n=47)according to coronary artery angiography result.Mortality of 30 days,peak value of CK-MB,ejection fraction(EF)and TIMI flow after PCI were compared.Results The occurance of high-burden thrombus in infarct-related arteries was 35.6% which was more often common in right coronary artery.The rate of TIMI3 flow after PCI in high-burden thrombus group was lower than that of the low-burdn thrombus group.The 30-day-mortality and peak CM-MB level in the high-burden thrombus group was higher than that of the low-burden thrombus group.Conclusion High burden thrombus is an important factor of prognosis in elderly patients with acute myocardial infarction after emergency PCI.

Objective: To evaluate the efficacy and safety of acupuncture for the treatment of knee osteoarthritis and to provide evidence for its use in clinical practice. Methods: Eight databases were extensively searched up to March 2018. Randomized controlled trials (RCTs) comparing the efficacy of acupuncture with sham acupuncture or no acupuncture for knee osteoarthritis were included. Study selection, data extraction and quality assessment were independently conducted by two reviewers. The Cochrane Collaboration's tool was used for assessing the risk of bias. Results: A total of 18 RCTs were included, involving a total of 3522 participants. The results showed that acupuncture was superior to sham acupuncture in relieving pain (SMD=-0.34, 95％CI:-0.57 to -0.11, I2=85％, P=0.003) and improving physical function (SMD=-0.34, 95％CI: -0.57 to -0.11, I2=85％, P=0.003). In comparison to the no-acupuncture group, the acupuncture group also showed significant advantages in relieving pain (SMD=-0.79, 95％CI: -1.15 to -0.43, I2=87％, P<0.0001) and improving physical function (SMD=-0.75, 95％CI:-1.19 to -0.31, I2=91％, P=0.0008). Sensitivity analyses suggested that the results were robust, and Egger's test found no potential publication bias. Conclusion: In the treatment of knee osteoarthritis, the acupuncture group had significant advantages over sham acupuncture or no-acupuncture groups in relieving pain and improving physical function.

A new benzene derivative microintegerrin C (1) and a new norsesquiterpenoid microintegerrin D (2), along with six known compounds (3-8), were isolated and identified from stems and leaves of Micromelum integerrimum by various chromatographies such as silica gel, Sephadex LH-20, RP-18 column chromatography and HPLC. Their structures were mainly identified based on the spectral data analysis such as 1D-, 2D-NMR and HR-EI-MS. All known compounds were isolated from this plant for the first time.

We aimed to study the effect of allitridum (All) on the transient outward potassium current (Ito) of ventricular myocytes of spontaneously hypertensive rats (SHR). Totally 30 male SHRs were randomly divided into three groups: low-dose All group (7.5 mg·kg(-1)), high-dose All group (15.0 mg·kg(-1)) and normal saline group. The other 10 sex and age matched Wistar-kyoto rats (WKY) were also taken as control group (WKY group). All animals received i.p. administration for 8 weeks. The dual enzymatic method was used to separate single ventricular myocyte from animals. Patch-clamp technique was used to record Ito and analyze the effect of All on the current. It was shown that the left ventricular hypertrophy of SHR was reversed significantly by All. Furthermore, the density of Ito was recovered in both high and low dose All groups. The peak current densities of Ito were enhanced from 18.23±3.64 to 25.17±2.86 pA/pF (P<0.01) and 36.47±5.42 pA/pF (P<0.01) at +50 mV by All 7.5 mg·kg(-1) and 15.0 mg·kg(-1), respectively, which was not significantly different with WKY group. The effect was associated with positive shift of the steady-state, close-state inactivation, and shortened recovery from inactivation of Ito. It is concluded that All decreases the remodeling of Ito of ventricular hypertrophic myocytes of SHR.

OBJECTIVETo investigate serological and genetic characteristics for an individual with cisAB06, an ABO blood subtype.

METHODSAntigens on red blood cells from the ABO blood group discordant individual were validated by monoclonal antibodies. The ABO antibodies in serum were validated by standard A, B, O cells. ABO genes were analyzed by polymerase chain reaction-sequence specific primer (PCR-SSP). Exons 6-7 of A/B genes were amplified with specific PCR, and the products were directly sequenced.

RESULTSBoth A and B antigens were detected on red blood cells from the proband. There was also anti-A antibody in the serum. The result of PCR-SSP has suggested a B/O02 phenotype. Direct sequencing revealed that the gene was cisAB06. Compared with B101 allele, the cisAB06 allele featured a single nucleotide change (G>C) at position 526 which resulted in an amino acid substitution (G176R).

CONCLUSIONG>C at nt526 of B allele can produce a cisAB06 allele. The serological phenotype of the specimen is therefore type AB.

Acupuncture and moxibustion for treatment of neurogenic bladder dysfunction after spinal cord injuries at home and abroad in recent years is introduced. The acupuncture and moxibustion methods for treatment of this kind of disease are classified and analyzed from body acupuncture, electroacupuncture, acupoint pressure and massage, acupoint-injection, acupoint sticking and so on. Acupuncture and moxibustion are widely applied to treatment of neurogenic bladder dysfunction after spinal cord injuries, with definite therapeutic effect and good safety. The effectiveness of other evaluation indexes of acupuncture and moxibustion for treatment of neurogenic bladder dysfunction after spinal cord injuries needs to be proved by more randomized and controlled trials of high quality with strict design and scientific methods.
