[Objective] To investigate the effect of Xiaocuo Prescription (XP), a herbal medicine compound with the actions of clearing away heat and toxins, activating blood and removing blood-stasis, on acne vulgaris. [Methods] Four hundred and forty six cases of acne vulgaris were randomized to two groups: group A (325 cases) treated with oral use of XP (mainly composed of Flos Lonicerae, Herba Hedyotis Diffusae, Herba Taraxaci, Flos Chrysanthemi, Radix Scutellariae, Cortex Mori, Radix Salviae Miltiorrhizae, etc.) and external application of Acne Vulgaris Liquid (composed of 3% metronidazole and 2% erythromycin), group B (121 cases) treated with oral use of isotretinoin and external application of Acne Vulgaris Liquid. Skin lesions on the face as well as the side effects were observed before and after treatment. [Results] Ridit analysis showed that curative effect in group A was better that in group B ( u = 2.204 6, P .05). No obvious side effects were found in group A but in 5 cases of group B side effects such as skin dryness, nausea and vertigo were found. [ Conclusion ] XP is effective in treating acne vulgaris . Further research is needed for its therapeutic mechanism.

Objective To screen and clone the target genes transactivated by hepatitis C virus (HCV) core protein. Methods The mRNA was isolated from HepG2 cells transfected with pcDNA3.1(-)-core and pcDNA3.1(-) empty vector, respectively, and suppression subtractive hybridization (SSH) method was employed to analyze the differentially expressed DNA sequences of the two groups. The obtained sequences were searched for homologous DNA sequence from GenBank. One of them was confirmed to be a new gene without homology with known genes in this database.Then, electric polymerase chain reaction was conducted for the cloning of the full-length DNA of the new gene, in conjunction with Kozak rule and the existence of polyadenyl signal sequence. The reverse transcription PCR (RT-PCR) was used to amplify the new gene with mRNA from HepG2 cell as the template. The coding sequence for the new gene was deduced according to the nucleotide sequence. Results A new gene with unknown function was named TAHCCP1.The nucleotide sequence of the new gene and its corresponding protein-encoding amino acid, which was 2 001nt and composing 667aa, have been determined. The sequence of the TAHCCP1 gene has been registered in GenBank with its accession number AY038359. Conclusion TAHCCP1 gene transactivated by HCV core protein was cloned and identified successfully by a combination of molecular biological technology and bioinformatics technique. The results are expected to pave the way for the study of the molecular mechanism of the transactivating effects of HCV core protein and the development of new therapies for chronic hepatitis C.

OBJECTIVE To study the possibility of acellular bony microtubule used to construct tissue engineering ossicular prosthesis. METHODS To prepare the acellular bony microtubule, observe the change of its histocompatibility and biomechanics. The acellular bony microtubule carried with collagen/ BMP-2 was implanted into the middle ear of the animals. The ectopic osteogenesis was observed. RESULTS The acellular bony microtubule has good histocompatibility. There wasn’t significant change about biomechanics. After carried with collagen/BMP-2, the bony microtubule can induce osteogenesis in the animal’s middle ear. CONCLUSION The acellular bony microtubule carried with collagen/BMP-2 has the possibility to be used to construct tissue engineering ossicular prosthesis.

Objective: This study was to observe the changes of IL-6 gene expression in acute repetitive hypoxia. Method: When the ratio of living cells was more than 95%, nerve cells cultured were passed through with mixed gases of 95% N_2+5%CO_2 for 3 min followed by another gases mixture of 95% O2+5% CO_2 for 10 min. After repeated the experiment as above, the alteration in the expression of IL-6 gene was measured using the RT-PCR method. The prod ucts of PCR were analyzed with computer Gel imaging and image analysis instrument. Result: After the first hypoxia IL-6 gene expression enhanced, and after the second hypoxia, it was still stronger than baseline although it declined slightly. There was no significant RNA disintegration. Conclusion:The IL-6 involves in the cellular defense in hypoxia adaptation.

There is a kind of intrinsic correlation between achievements and age.The average years of age of the scientists awarded the Nobel prizes in five fields are 30.9~33.3.Lots of ancient and modern scientists in many fields are similar to this.Therefore young people are able to make significant achievements,especially innovative achievements.This law is not well cogitated in our country,especially by the young themselves.To understand this law correctly will be of certain inspiration and significance not only for people from different age bracket to make achievement but also beneficial to improving the innovative capability of the whole country.

Objective To evaluate the influence of precise liver resection techniques on intestinal permeability in the diseases needing liver resection.Methods Eighty-seven patients needing liver resection were randomized to receive the precise liver resection (n =58,PLR group) or the conventional liver resection (n =29,CLR group).D-lactate and and endotoxin in abdominal fluid were detected in all the patients.The abdominal fluid bacteria cultures were performed.Results The postoperative hospitalization time,the needed time of blood routine,temperature,and oppetite resuming were significantly shorter in PLR group than those in CLR group (t ≥7.36,P ＜ 0.01) ; The postoperative abdominal effusion was significantly less in PLR group than that of CLR group(t ≥ 14.17,P ＜0.01).The abdominal fluid concentrations of D-lactate and endotoxin in operation or at 1d after operation were significantly higher than those at 5d after operation in both groups(t ≥10.41,P ＜0.01).Those parameters decreased significantly at 2d after operation,returned to the normal level at 3d after operation in PLR group,and those parameters were significantly lower in PLR group than those in CLR group at the same time phase after postoperative 2 or 3 days (t ≥9.23,P ＜0.01) ; Those parameters began to drop at 3d after operation,returned to the normal level at 5d after operation in CLR group.The positive rate of abdominal fluid bacteria cultures was significantly lower in PLR group than that in CLR group(13/29) (x2 =23.51,P ＜ 0.01).Conclusions The precise liver resection techniques had an important influence on intestinal permeability in the diseases needing liver resection.

Objective To investigate deficient inhibitory control in individuals with IAD using a visual go/no-go task by ERPs. Methods 26 individuals met YDQ criteria for IAD were enrolled as research group and marched sexual and age 26 healthy person enrolled as control group. BIS-11 was used for measures of impulsivity.A go/no-go task involved eight different two-digit numerical stimuli. The response window was 1000 ms and the ITIwas 1500 ms. EEG was recorded during participants performed the task. BESA 5.2.0 was used to perform data analysis and the no-go N2 amplitude was analyzed for investigation of inhibitory control. Results BIS-11 total scores, attentional key scores and motor key in IAD group were higher than that of control group. In the go/no-go task, false alarm rate of IAD group was higher and hit rate was lower than that of control group. A repeated measure ANOVA revealed a significant group, frontal electrode sites and group × frontal electrode sites main effect for N2amplitudes of no-go conditions ( for group: F= 3953, df= 1, P= 0.000;for frontal electrode sites: F= 541, df= 9, P= 0.000;for group × frontal electrode sites: F = 306, df = 9, P = 0. 000 ), and a significant group, central electrode sites and group × central electrode sites main effect for N2 amplitudes of no-go conditions ( for group: F=9074, df= 1, P = 0. 000;for central electrode sites: F = 163, df= 2, P = 0.000;for group × central electrode sites: F = 73, df= 2, P = 0.000). N2 amplitudes of no-go conditions were lower than those at control group. Conclusions Individuals with IAD were more impulsive than controls and shared neuropsychological and ERPs characteristics of compulsive-impulsive spectrum disorder, which supports that IAD is an impulse disorder or at leastrelated to impulse control disorder.
