OBJECTIVETo explore the therapeutic effect of acupuncture for hypertensive cerebral hemorrhage at the early stage.

METHODSFifty-four cases of small-amount cerebral hemorrhage were randomized into an acupuncture group and a conventional treatment group, 27 cases in each one. In the conventional treatment group, special care, oxygen therapy, nerve nutrition and symptomatic support were applied. In necessary, dehydrant and hypotensive drugs were prescribed for antihypertension, or surgery was given. In the acupuncture group, on the basis of the treatment as the control group, acupuncture was applied at Quchi (LI 11), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3). Acupuncture was given at the admission, 4 h, 6 h and 12 h after disease onset respectively. Blood pressure was monitored in the whole procedure. 6 h and 24 h after disease onset, the cranial CT was re-examined. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), hematoma volume and neurological deficit score were compared at different time points between the two groups.

RESULTS(1) Blood pressure: from the admission to 12 h after disease onset, SBP, DBP and MAP were increased apparently in the conventional treatment group and increased slightly in the acupuncture group. The differences in SBP [(164.3 +/- 21.6) mmHg vs (158.6 +/- 21.5) mmHg] and MAP [(113.4 +/- 4.9) mmHg vs (106.7 +/- 6.1) mmHg] were significant between the two groups (both P < 0.05). From 12 h to 24 h after disease onset, compared with the conventional treatment group, SBP and MAP were decreased apparently in the acupuncture group [(147.3 +/- 21.6) mmHg vs (158.4 +/- 23.5) mmHg, (97.2 +/- 5.3) mmHg vs (106.6 +/- 5.1) mmHg, both P < 0.05)]. (2) Hematoma volume: from the admission to 6 h after disease onset, the volume was increased by (4.15 +/- 0.73) mL in the convertional treatment group and (2.67 +/- 0.33) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). From the admission to 24 h after disease onset, it was increased by (5.57 +/- 1.26) mL in the convertional treatment group and (3.14 +/- 1.18) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). (3) Neurological deficit score: the score was increasing gradually in first 3 days after disease onset in the two groups. The score (38.39 +/- 6.84) in the acupuncture group on the first day was different significantly as compared with that (42.37 +/- 7.46) in the conventional treatment group (P < 0.05). On the 10th days, the score (24.68 +/- 5.42) in the acupuncture group was different significantly from that (29.74 +/- 7.36) in the convertional treatment group (P < 0.05).

CONCLUSIONThere is no peak of blood pressure rising, and the continuous hemorrhagic volume is less in 24 h and neurological deficit score is improved in the acupuncture group. Acupuncture brings the positive significance in the treatment of cerebral hemorrhage at the early stage.

Complex genetic variation has been known to occur during the transmission of human enterovirus (HEV), and the HEV virulence and pathogenicity enhanced by genetic recombination also pose a serious threat to human health. In recent years, the interest in recombination mechanism of genetic plasticity has been renewed with the emergence of pathogenic recombinant circulating vaccine-derived polioviruses, which were implicated in poliomyelitis outbreaks in several regions of the world with insufficient vaccination coverage. This paper reviews recent research progress in HEV genome, including evolutionary characteristics, recombination types, and in vitro recombinant construction.

Objective To investigate the effects of ultrasound-targeted microbubble destructionmediated MicroRNA-21 on cardiomyocyte apoptosis after coronary microembolization (CME) in swine.Methods Twenty Bama miniature swine were randomLy (random number) divided into sham-operated,CME,CME plus gene transfection and CME plus ultrasound mediated gene transfection groups (n =5 per group).The CME model was established by microcatheter-mediated injection of microspheres into the left anterior descending artery.The sham-operated group were made by injection of saline instead.The CME plus ultrasound mediated gene transfection group was made by injection of plasmid-microbubble mixture through the marginal ear vein 4 days before CME established.Meanwhile,ultrasound treatment was given to the myocardium through chest wall.The CME plus gene transfection group was made by injection of plasmidmicrobubble mixture through the marginal ear vein 4 days before CME established without exposure to ultrasound.Left ventricular ejection fraction (LVEF) was examined by cardiac ultrasound.Tissue biopsy was stained with hematoxylin-eosin (HE) and hematoxylin basic fuchsin picric acid (HBFP) to measure the size of infarction area.Green fluorescent protein (GFP)-labeled gene expression was evaluated by fluorescent microscopy in frozen sections.Cardiomyocyte apoptosis was detected with terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end-labeling (TUNEL staining).The expression of PTEN mRNA was measured by fluorescent quantitative PCR.The levels of PTEN protein and Caspase-3 protein was measured by western blot.Results ①Compared to CME plus gene transfection group,the CME plus ultrasound mediated gene group had over eightfold expression of exogenous genes in myocardium (P ＜ 0.05) measured by using optical density of green fluorescence protein;② Compared with shamoperated group [(67.87 ±2.36)％],the LVEF of CME group [(50.94 ±3.52)％] and CME plus gene transfection group [(52.47 ±3.71)％] were markedly decreased (P ＜ 0.05).Compared with CME group,the CME plus ultrasound mediated gene transfection group [(64.79 ± 2.95)％] improved CME-induced cardiac dysfunction as evidenced by increased LVEF (P ＜ 0.05);③Compared with sham-operated group,the expression of PTEN mRNA and levels of PTEN protein and Caspase-3 protein in the CME group increased significantly (P ＜ 0.05).Compared with CME group,the levels of PTEN protein and Caspase-3 protein and the expression of PTEN mRNA in CME plus ultrasound mediated gene transfection group was dramatically decreased (P ＜ 0.05).Conclusions Ultrasound microbubble-mediated MicroRNA-21 transfection effectively improved CME-induced cardiac dysfunction by down-regulating the expression of targeted gene PTEN in myocardial cells,mainly reducing the post-CME myocardial cell apoptosis.

To discover novel fluoroquinolone lead compounds as possible anti-infective or/and antitumor chemotherapies, combination principle of pharmacophore-based drug design, a series of novel tricyclic fluoroquinolone title compounds, [1,2,4]triazino[3,4-h][1,8]naphthyridine-8-one-7-carboxylic acid derivatives ( 5a-5p), were designed and synthesized with a fused [1,2,4]-triazine ring unit. Their structures were characterized by spectral data and elemental analysis and the in vitro antibacterial and anti-cell proliferation activities were also evaluated. The results showed that the titled compounds exhibited more significant inhibitory activities against drug-resistant bacteria (Methicillin-resistant Staphylococcus aureus and multi drug-resistant Escherichia coli strains) and three tested cancer cell lines (human hepatoma SMMC-7721, murine leukemia L1210 and human murine leukemia HL60 cells). Interestingly, SAR showed that compounds with electron-donating groups attached to benzene ring had stronger antibacterial activity than antitumor activity, but electron-withdrawing compounds displayed more potential antitumor activity than antibacterial activity, especially antitumor activity of nitro compounds was comparable to comparison doxorubicin. Thus, novel triazine-fused tricyclic fluoroquinolones as potent anti-infective or/and antitumor lead compounds are valuable to pay attention and for further development.

To explore an efficient strategy for the conversion of antibacterial fluoroquinolones into antitumor fluoroquinolones, an azole heterocyclic ring of oxadiazole instead of the C-3 carboxylic acid group with a functionalized hydrazone group as a modified side-chain, fifteen novel 2-(fluoroquinolon-3-yl)-oxadiazole-5- sulfanylacetylhydrazone derivatives 7a-7o were designed and synthesized on the basis of the pharmacophore hybridization principle from pefloxacin, separately. The structures for fifteen title compounds were characterized by elemental analysis, 1H NMR and MS, and their in vitro antitumor activity against Hep-3B cell line was evaluated by a MTT assay. The results showed that the title compounds exhibited more significantly inhibitory activity than that of the parent pefloxacin, in which compounds with electron-withdrawing group attached on aryl ring had more potency than that of compounds with electron donating group, especially compounds with a carboxylic substituent were comparable to comparison doxorubicin. It suggests that it is favorable for an improvement of antitumor activity to remain a carboxylic acid unit at the aromatic ring.

Background The diagnosis and treatment of fungal keratitis are knotty.There is no quantitative method to identify the disease and judge the therapeutic effect of the antifungal agent.Studies have determined that serum (1,3-) β-D-glucan level can sensitively and specifically reflect the state of systemic mycotic-causing diseases.However,whether (1,3-) β-D-glucan level in tear can monitor and diagnose mycotic keratitis is unclear.Objective Purpose of this study was to investigate the change of tear (1,3-) β-D-glucan level following the administration of antifungal drug in fungal keratitis patients,and evaluate the diagnosis and monitor value of (1,3-) β-D-glucan in tears for fungal keratitis.Methods Sixty patients who were diagnosed as fungal keratitis by fungal culture were analyzed in Affiliated Hospital of Qingdao University Medical College from July 2010 to May 2012.The patients received the topical administration of antifungal drug for 28 days.Thirty healthy volunteers without eye disease served as normal controls.The tear of 50 μl was collected from each subject for the detection of (1,3)-β-D-glucan before the therapy,7,14,28 days after therapy and 7 days,14 days after the drugs were stopped,respectively.The dynamic changes of (1,3-) β-D-glucan levels in tears were evaluated and compared with the manifestation of the lesions under the laser scanning confocal microscope.The patients without hyphal by the laser scanning confocal microscopy and tear (1,3-)β-D-glucan level less than 20 ng/L were subsequently treated for another 7 days,and the following-up duration was 2 months.The informed consent was obtained before any medical examination was performed from each subject.Results (1,3-)β-D-glucan level in tears (Log value) was (6.37 ±0.48)ng/L in the patient group,and was significantly higher than (2.00±0.31) ng/L in the normal control group (t =2.89,P＜0.01).The lesion was smaller with the gradually clear border,and the number of mycelia was decreased under the laser scanning confocal microscope 7 days after treatment.(1,3-) β-D-glucan level in tears was gradually declined in a time-dependent manner after treatment.The (1,3)-β-D-glucan level in tears (Log) was (5.19 ± 0.42),(4.16 ± 0.33),(2.99 ±0.42),(2.91 ±0.39),(2.80±0.40) ng/L 7,14,28 days after treatment,and 7 days,14 days after the drugs were stopped,respectively,with a statistically significant difference in comparison with (6.37±0.48)ng/L before treatment (P＜0.01).(1,3)-β-D-gluean level in tears remained a lower level till the end of follow-up,and no recurrence of lesion was found in the patient group.Conclusions Detecting (1,3)-β-D-glucan level in tears is of good diagnosis and monitor value in the evaluation of fungal keratitis.

OBJECTIVETo observe clinical therapeutic effect of acupuncture kinetotherapy for acute simple laryngitis of wind-heat type and to probe the mechanism.

METHODSEighty cases were randomly divided into a test group and a control group, 40 cases in each group. The test group were treated with acupuncture kinetotherapy (Acupuncture was given at Kaiyin point No. 1 combined with deep respiratory movement of the glottis), once daily. The control group were treated with ultrasonic aerosol inhalation of 0.9% sodium chloride injection, gentamicin sulfate injection 80 000 U and Dexamethasone injection 5mg, twice a day. The treatment was given for 5 days for the 2 groups.

RESULTSThe cured and markedly effective rate was 90.0% in the test group and 82.5% in the control group with no significant difference between the two groups (P>0.05); in the test group there was a very significant difference before and after treatment in the cumulative score of symptoms and the acoustic parameters (P<0.01).

CONCLUSIONAcupuncture kinetotherapy has obvious therapeutic effect on acute simple laryngitis of wind heat type, with no toxic and adverse effects.
