OBJECTIVETo investigate the protective effect of Danxuetong injection (DXT, a combination of Danshen and Xueshuantong injections) against testicular ischemia-reperfusion injury following testis torsion/detorsion in rats.
METHODSThirty-two 4-week-old healthy male SD rats were randomly divided into four groups of equal number: sham operation, normal saline, single DXT injection, and successive DXT injection. The rat models of testicular ischemia-reperfusion injury were established by 2-hour 720-degree torsion/detorsion of the unilateral testis. At 6 weeks after modeling, the rats were killed and their testes were harvested for measure- ment of testicular coefficients, sperm counts, sperm motility, and the levels of total anti-oxidative capacity (T-AOC) , superoxide dismutase (SOD) , nitric oxide synthase (NOS) , and malondialdehyde ( MDA) in the testis tissue.
RESULTSCompared with the rats of the normal saline group, those of the single DXT injection and successive DXT injection groups showed significant increases in the testicular coefficient (0.11 ± 0.03 vs 0.35 ± 0.04 and 0.40 ± 0.06, P < 0.05), sperm count ([0.46 ± 0.10] vs [1.44 ± 0.50] and [3.00 ± 1.28] x10(9)/ml, P < 0.05), sperm motility ([13.63 ± 14.04] vs [39.63 ± 5.04] and [76.31 ± 3.67]%, P < 0.05), the activity of SOD (72.76 ± 5.58 vs 116.25 ± 8.83 and 133.20 ± 13.84, P < 0.05), and the level of T-AOC (5.58 ± 1.07 vs 13.34 ± 5.81 and 19.21 ± 5.69, P < 0.05), but a remarkable decrease in the content of MDA (42.38 ± 8.94 vs 20.94 ± 5.65 and 15.02 ± 1.03, P < 0. 05) in the injured testes.
CONCLUSIONDXT can effectively rid the testis tissue of oxygen free radicals, improve sperm count and motility by antioxidation, and protect the testis tissue of prepubertal rats against testicular ischemia-reperfusion injury after testis torsion/detorsion. It also has a protective effect on the contralateral testis, and successive injection has a better effect than single injection of DXT.

Objective: To observe the clinical effect of acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus electroacupuncture (EA) for treating peripheral facial paralysis and its influence on patients' facial nerve functions, facial disability index and clinical symptoms and signs. Methods: A total of 96 peripheral facial paralysis patients were allocated into an observation group, a medicine group and an EA group by simple randomization, with 32 cases in each group. Patients in the medicine group were treated with oral mecobalamine and prednisone acetate; patients in the EA group were treated with EA on the basis of the medicine treatment; while patients in the observation group were treated with acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus EA. After 4-week treatment, the clinical efficacy, the adverse events, and the scores of House-Brackmann (H-B) facial nerve function grading scale, visual analog scale (VAS), clinical symptoms and signs, and facial disability index (FDI) were compared. Results: After 4-week treatment, the total effective rate was 96.9% in the observation group, higher than 68.7% in the medicine group and 75.0% in the EA group (both P<0.05). After 4-week treatment, the scores of H-B grading scale, VAS and clinical symptoms and signs in the three groups dropped significantly compared with those before treatment, and the scores in the observation group were lower than those in the medicine group and EA group (all P<0.05). After 4-week treatment, the facial disability index-physical function (FDIP) in the FDI in the three groups increased significantly, with a higher value in the observation group compared with that in the medicine group and EA group (both P<0.05). The facial disability index-social function (FDIS) in the FDI dropped significantly, with a lower score in the observation group compared with that in the medicine group and EA group (both P<0.05). However, the comparisons of the items above between the medicine group and the EA group showed no statistical significance (all P>0.05). The between-group comparison of the adverse event across the three groups showed no statistical significance (P>0.05). Conclusion: Acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus EA can decrease H-B grade, reduce pain severity and improve clinical symptoms and signs as well as the facial disability condition in peripheral facial paralysis patients. This method produced more significant efficacy compared with oral medicine and medicine plus EA.

OBJECTIVEHigh altitue pulmonary edema (HAPE) impacts seriously people's health at high altitude. Screening of susceptibility genes for HAPE will be used for the evaluation and protection of susceptible people.
METHODSWe performed a genome-wide association study (GWAS) using Affymetrix SNP array 6.0 in 23 HAPE patients and 17 healthy controls. GO and Pathway analysis softwares were used to analyze and draw gene network.
RESULTSThirty-nine SNPs were found to be significantly different between case and control groups (P < 10(-4)). GO and Pathway analysis of 27 genes around the 39 SNPs indicated that these genes mainly participate in the regulating of cell proliferation, regulation of nitrogen compound metabolic process and G-protein coupled receptor protein signaling pathway and so on.
CONCLUSIONIt suggests that these SNPs and genes found in this study may be associated with the susceptibility of HAPE.

To construct the pharmacophore model of the poly (ADP-ribose) polymerase-1 inhibitor and to investigate the possible inhibitory mechanisms, ten pharmacophore models of PARP-1 inhibitor were established from the training set of thirty-eight PARP-1 inhibitors with conformer analysis and pharmacophore mapping by using the Catalyst software. Based on the mechanism of action and the known structure-activity relationship of PARP-1 inhibitor, an optimal pharmacophore model including two hydrogen-bonding acceptors and two aromatic hydrophobic core was confirmed. The reliability of the optimal pharmacophore model is preferably with RMS = 0.46, Correl = 0.91, Weight = 2.06, and Config = 15.97. This pharmacophore model not only provided some information about the interaction between enzyme and compound, but also showed excellent forecast ability and contributes to design the PARP-1 inhibitors with undiscovered structure.

OBJECTIVE:
To investigate the numbers, sizes and types distribution of diatoms in drowned and postmortem immersed rabbits' lungs.
METHODS:
Sixty-two rabbits were randomly divided into drowning group (n = 30), postmortem immersion group (n = 30) and land death group (n=2), and the diatoms in each lung lobe were analyzed quantitatively and qualitatively by microwave digestion and scanning electron microscopy.
RESULTS:
In the drowning group, the diatoms were detected in each lung lobe with Cyclotella and Melosira in the majority. In the postmortem immersion group, Cyclotella was in the majority. And the diatoms weren't detected in some lung lobes in postmortem immersion. There were significant differences in the detection rates of upper lobe of left lung, middle lobe and cardiac lobe of right lung in two groups (P < 0.05).
CONCLUSION
Based on the microwave digestion and scanning electron microscopy, the numbers, sizes and types distribution of diatoms in drowned and postmortem immersed rabbits' lungs can be analyzed and used as references for testing theory.
