Objective To estimate the clinical efficacy of naloxone and trimetazidine in the treatment of severe viral myocarditis.Methods40 patients with severe viral myocarditis were randomly divided into two groups: control group(20cases) and treatment group(20 cases).All patients in control group and treatment group received conventional therapy.In adition,the patients in treatment group received naloxone and trimetazidine treatment.After 14 days,the changes of clinical symptoms were observed.In addition,serum creatinine kinase(CK)-MB and cardiac troponin I(cTnI) levels were measured.ResultsAlthough the symptoms,CK-MB and cTnI were significantly improved in two groups,but significant difference was still found between control group and treatment group(P

Objective To investigate the gender difference in the smile aesthetic features in aged Han Chinese with normal occlusion and its clinical significance.Methods Fifty-six aged Han Chinese (male:28,female:28,aged 60-66 years)with normal occlusion were included in this study.Smiling images of the resting-position and mandibular postural position were obtained in an anteriorposterior view.The CoSmileMAA1.0 software was used to evaluate the indices associated with the smile-aesthetic features,and its clinical significance was analyzed.Results Significant differences were noted in the nasal ala width,upper lip length,lip clearance,angle oris width in resting-position/ smiling position together with the changes of lip clearance,angle oris width,distance of inferior margin of upper lip to cutting edge of the maxillary incisor teeth,distance of superior border of lower lip to cutting edge of the maxillary incisor teeth,smile line ratio and type of smile (all P＜0.05).When the subjects were smiling,the changes of lip clearance was greater in females than in males [(10.7±1.9)mm vs.(11.3±1.6)mm,P＜0.05],the changes of angle oris width was greater in males than in females [(14.1±1.6)mm vs.(13.4±1.3)mm,P＜0.05],and the smile line ratio was less in males than in females [(0.9±0.2) vs.(1.1±0.5),P＜0.05],which indicate that the females had more attractive smile in aged Han Chinese with normal occlusion than males.The type of smile was mainly high smile in elderly females and median smile in elderly males [53.6％ (15 cases) and 60.7％ (17 cases),x2 =6.43,P＜0.05].Conclusions Significant gender difference is noted in the smile-aesthetic features in aged Han Chinese with normal occlusion.Modulation of maxillary incisor teeth length and smile line ratio can contribute to the aesthetic appearance of smiling.

Objective To investigate the protective effect of Xinyi capsule pretreatment on myocardial ischemia reperfusion injury in rabbits and its possible mechanism. Methods Ninety-four rabbits were randomly divided into 6 groups: model group (n=16), tirofiban group (n=16), high-, medium- and low-dose Xinyi capsule groups (4.0, 2.0, 1.0 g/kg;n=16 in each group), and sham operation group (n=14). Five days after intragastric administration with drug, myocardial ischemia reperfusion was induced by ligation of the proximal left circumflex artery. The electrocardiogram (ECG) was continuously recorded. The serum levels of myeloperoxidase (MPO), lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB) were measured. Myocardial histopathological damage was evaluated. Results The changes of J-point amplitude on ECG in high-, medium-and low-dose Xinyi capsule groups (0.064 ± 0.049 mV, 0.069 ± 0.061 mV, 0.079 ± 0.060 mV) were significantly lower than that in the model group (0.158 ± 0.105 mV, P<0.01 or P<0.05), the serum levels of LDH (399.7 ± 202.3 U/L, 369.6 ± 229.0 U/L, 435.5 ± 152.4 U/L), CK-MB (900.8 ± 231.2 U/L, 1 268.3 ± 899.8 U/L, 1 386.7 ± 621.6 U/L), MPO (69.81 ± 5.51 U/L, 85.44 ± 10.31 U/L, 81.33 ± 16.87 U/L) were significantly lower than those in the model group (LDH:817.1 ± 401.9 U/L, CK-MB:2 071.3 ± 693.5 U/L, MPO:149.9 ± 20.11 U/L;P<0.01 or P<0.05). Histopathological examination showed that myocardial damage in high-, medium- and low-dose Xinyi capsule groups reduced compared with the model group. Conclusions Xinyi capsule pretreatment can protect against myocardial ischemia reperfusion injury in rabbits, and its mechanism may be related to inflammation inhibition.

Objective To design the small interference RNA (siRNA) specific to human CCL20 gene by RNA interfering technique, construct its recombinant lentiviral expression vectors, and identify these vectors by DNA sequencing. Methods According to Tuschl’s principle, the siRNA was designed and converted into cDNA of shRNA (small hairpin RNA) of siRNA for CCL20 gene. The cDNA was synthesized and inserted into plasmid pHSER-dsRNA-GFP-SIN which was linearized by restriction endonucleases SpeⅠ and SalⅠ. The recombinant plasmid was transformed into competent E. coli. DH5? cells. The positive recombinant colony was selected by ampicillin medium agar and identified by DNA sequencing. Results Two recombinant lentiviral plasmids of siRNA specific to CCL20 gene were constructed successfully. Their DNA sequence analysis completely coincided with their designed sequences. Conclusion Lentiviral vector-based siRNA expression plasmids against CCL20 gene have been successfully constructed and identified. They will be further used for interfering CCL20 mRNA transcription and lay the foundation for CCL20 gene modified human keratinocyte stem cells.

Objective To study the effects of hyperbaric oxygen （HBO） therapy in patients with acute intracerebral hemorrhage on serum adhesion molecules. Methods 66 cases with acute intracerebral hemorrhage were divided into routine treatment group (n=33) and HBO treatment group (n=33). 30 health persons were selected as normal trontrol. The level of adhesion molecules, including intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and E-selectin, were measured before and after treatment. Results The levels of adhesion molecules in routine and HBO treatment groups were higher than those in normal control group when hospitalized (P<0.01). All the adhesion molecules levels in two treatment group were decreased after the treatment, and more significantly in HBO group (P<0.05). Conclusion HBO therapy may ameliorate the adhesion molecule abnormalities after intracerebral hemorrhage.

OBJECTIVE LW- AFC is extracted from the classical traditional Chinese medicinal prescription-Liuwei Dihuang Decoction. Previous studies have showed that LW-AFC could improve learning & memory ability in amny animal models. In this study, we focused on evaluating the effect of several main active components from LW-AFC (B-B; loganin, LOG; morroniside, MOR; paeoniflorin, PF and stachyose, STA) on LTP. METHODS In vivo recording of LTP was used in this study to evaluate the effects of LW-AFC and it's active components on coticorsterone (Cort) induced LTP impairment. RESULTS The results showed that LW-AFC could ameliorate Cort-induced LTP impairment. The effect of LW-AFC was abolished when the immune function was inhibited. Single administration (ig, ip, icv) of any of the components had no effect on Cort-induced LTP impairment. Consecutively intragastric admin?istration or intraperitoneal injections (chronic administration) of B-B, LOG, MOR or PF for 7 d showed protective effect on Cort-induced LTP impairment. Intragastric administration of STA for 7 d protected LTP from impairment induced by Cort, while there was little improving effect when STA was administrated via intraperitoneal injection. In addition, when the intestinal microbiota was disrupted by applying the antibiotic cocktail, STA showed little protective effect against Cort. CONCLUSION In conclusion, LW-AFC and it' s components showed positive effects against cort induced LTP impairment, it seems that all displayed protective effects via indirectly, immune modulation might be the common pathway for all components; the exact pathways are different in each component, B-B, LOG, MOR and PF could be absorbed into the bloods tream and then modulate the peripheral immune function, while STA could not be absorbed and modulates the immune function via modulating intestinal microbiota. Further studies are needed to invesgate the underlying mechanisms and the synergetic effects of all components.
