OBJECTIVETo compare the therapeutic effects of peripheral facial paralysis in acute stage by different interventions and explore the better treatments of peripheral facial paralysis.

METHODSOne hundred and thirty one cases of Bell's facial paralysis were randomly divided into three groups. In acupuncture group (44 cases), Dicang (ST 4), Jiache (ST 6), Hegu (LI 4), Yangbai (GB 14) and Taiyang (EX-HN 5), etc. were applied; in electroacupuncture group (45 cases), the selection of acupoints and needling method were same as those in acupuncture group, and the electroacupuncture therapy was applied on Dicang (ST 4), Xiaguan (ST 7), Yangbai (GB 14) and Taiyang (EX-HN 5) in acute stage; in medication and acupuncture group (42 cases), Prednisone and Acyclovir were taken by oral administration, Vitamin B1 and Vitamin B12, were applied by intramuscular injection in acute stage, and acupuncture was applied by the way which was same as that in acupuncture group during quiescent and recovery stages. The curative effects were evaluated by House-Brackmann Grading Scale, and the failed rates were observed by follow-up after one and three months.

RESULTSThe cured and markedly effective rates were 79.6% (35/44), 93.4% (42/45) and 78.6% (33/42) respectively in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.05). The cured rates above tympanichord were 54.2% (13/24), 85.2% (23/27) and 48.0% (12/25) in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.01). There was no significant differences of cured rates below tympanichord among three groups (P > 0.05); and the failed rate in electroacupuncture group was much lower than those in acupuncture group and medication and acupuncture group by follow-up after one and three months (all P < 0.01).

CONCLUSIONThe peripheral facial paralysis is effectively treated by electroacupuncture in acute stage, and it suggests that electroacupuncture should be applied early during the acupuncture treatment of peripheral facial paralysis.

OBJECTIVETo prepare coated tablets of glycyrrhetinic acid and hydroxypropyl-beta-cyclodextrin (GTA-HP-beta-CYD) inclusion complex tablets for colon-specific release.

METHODIn order to improve the solubility of GTA, the GTA-HP-beta-CYD inclusion complex was prepared by ultrasonic-lyophilization technique and its formation were characterized by X-ray powder diffraction profiles and infrared spectrometry. The effects of inclusion condition on the inclusion efficiency and stability coefficient of inclusion complex were investigated, respectively. After prepared GTA-HP-beta-CYD tablets by powder direct compression, the pH dependant polymer Eudragit III and/or mixed with Eudragit II were used for further coating materials in fluid-bed coater. The influences of coating weight on the GTA release in different pH conditions were evaluated to establish the method for prepering colon specific delivery tablets with pulsed release properties.

RESULTThe formation of inclusion complexes were proved by X-ray powder diffraction profile and phase solubility curve. The effect of pH value of solvent was played critical role on the preparation of GTA- HP-beta-CYD inclusion complex. And the inclusion efficiency of GTA was 9. 3% and the solubility was increased to 54. 6 times at optimized method. The Eudragit III coated GTA- HP-beta-CYD tablets with coating weight 10% and 16% were showed pH dependant colon specific release profiles with slow release rate. The release profile of tablets coated with the mixture of Eudragit II and Eudragit III (1:2) were indicated typical pH dependant colon specific and pulsed release properties while the coating weight was 17%.

CONCLUSIONThe preliminary method for preparation of colon specific release tablets containing glycyrrhetinic acid with improved solubility was established for further in vivo therapeutic experiment.

To prepare the RNAse-resistant virus particles containing the partial gene fragments of avian influenza virus H5N1 for use as RNA standard and control in RNA virus detection, the genes coding the coat protein and maturase of E.coli bacteriophage MS2 were amplified by PCR and then cloned into prokaryotic expression vector pET32a to construct the intermediate vector pET32a-MS2. In addition, the gene sequences coding hemagglutinin (HA), neuraminidase(NA) and M protein of the H5N1 virus were also cloned separately to the down-stream of plasmid pET32a-MS2, thus constructing the prokaryotic expression vectors pET32a-NS2-HA, pET32a-MS2-NA and pET32a-MS2-M. These recombinant plasmids were then transformed separately to E.coli BL21(DE3) with induction by IPTG. to express the virus-like particles. The virus-like particles observed under electron microscopy were identified by RT-PCR ,while their stability was confirmed by real-time RT-PCR. In this way, the virus-like particles were successively constructed and identified through PCR amplification, enzymolysis identification and sequencing analysis. These virus-like particles observed under electron microscopy appeared to be circular in shape with a diameter of about 50 nm. Their stability was proved to be rather good. From these observations, it is apparent that these virus-like particles can be used as RNA standard and quality control in the detection of avian influenza virus H5N1.

Objective To discuss the frequent etiology of spontaneous sub-cortical hemorrhage and its diag- nosis.Methods The clinical materials of 79 cases of spontaneous sub-cortical hemorrhage were analyzed.Results 56% of the hemorrhage was caused by arterial-venous malformation.48% of the hemorrhage was caused by occult AVM.Conclusion AVM is the most frequent etiology of spontaneous sub-cortical hemorrhage.CTA plays a special role in its diagnosis.

One influenza H3N2 virus, A/swine/Shandong/3/2005 (Sw/SD/3/2005), was isolated from pigs with respiratory disease on a farm in eastern China. Genetic analysis revealed that Sw/SD/3/2005 was a triple-reassortant virus with a PB2 gene from human-like HIN1, NS from classical swine H1NI, and the remaining genes from human-like H3N2 virus. These findings further support the concept that swine can serve as reservoir or mixing vessels of influenza virus strains and maintain genetic and antigenic stability of viruses. Furthermore, we have successfully established a reverse genetics system based on eight plasmids and rescued Sw/SD/3/2005 through cell transfection. HI tests and RT-PCR confirmed that the rescued virus maintained the biological properties of the wild type Sw/SD/3/2005. The successful establishment of the reverse genetics system of Sw/SD/3/2005 will enable us to conduct extensive studies of the molecular evolution of H3N2 influenza viruses in swine.

Estrogen receptor alpha (ERalpha) has been a primary target of treatment as well as a prognostic indicator for breast cancer. The level of human X-box binding protein 1 (XBP-1) mRNA was related with that of ERalpha in breast tumors and was over-expressed in some breast tumors. These previous studies suggested that XBP-1 may interact with ERalpha. XBP-1 has two isoforms, XBP-1S and XBP-1U, as the result of unique splicing. GST pull-down assay showed that both XBP-1S and XBP-1U bound to ERalpha in vitro. The binding of XBP-1S to ERalpha was stronger than that of XBP-1U to ERalpha. Co-immunoprecipitation revealed that the binding was in a ligand-independent manner. XBP-1S and XBP-1U interacted with the region of ERalpha that contains a DNA-binding domain. The ERalpha-interacting regions on XBP-1S and XBP-1U have been mapped to two regions, the N-terminal basic region leucine zipper domain (bzip) and the C-terminal activation domain. These findings suggest that XBP-1S and XBP-1U may participate in ERalpha signaling pathway through the mediation of ERalpha.

Objective To prepare and study the immunogenicity of hepatitis B virus surface anti-gen (HBsAg)-tetanus toxoid (TT) conjugate vaccine. Methods Tr was activated by cyangen bromide and reacted with adipic acid dihydrazide, then HBsAg-TT conjugate was prepared by carbediimide. Conjugate, HBsAg or hepatitis B vaccine was injected subcutaneously into mice. Anti-HBsAg and HBsAg-specific T cell response elicited by these immunogens were assayed. Results New HBsAg-TT conjugate elicited higher levels of anti-HBsAg and HBsAg positive conversion rates after the immunization than did HBsAg alone or hepatitis B vaccine. Conjugate induced mesdy antibodies of the IgG2a subclass, while HBsAg alone or hepa-titis B vaccine mainly elicited anti-HBsAg in the IgG1 subclass. The number of IFN-γand IL-2 secreting T cells induced by conjugate was also significantly higher than that did by HBsAg or hepatitis B vaccine. Con-clusion This study indicated new HBsAg-TT conjugate can induce both stronger humoral and TH1 type of cellular immune response.

Objective: To analyze the clinical effect of traditionaldog-days acupoint application and Magic Acupuncture Patch (Manji) in the prevention and treatment of chronic bronchitis (CB) in remission stage in the past five years, and explore the principle of action and effective stimulation, to provide the evidence for treating CB by acupoint application. Methods: A retrospective study was conducted on 405 patients with CB who met the inclusion criteria. All patients were treated with dog-days acupoint application or Magic Acupuncture Patch between 2013 and 2017. The clinical data of 405 patients were statistically analyzed to compare the prevention and treatment effects of dog-days acupoint application and Magic Acupuncture Patch, and different degrees of stimulation of dog-days acupoint application. Results: Among the dog-days acupoint application groups, the total effective rate was 63.6％ in the light stimulation group, 93.1％ in the moderate stimulation group, and 94.8％ in the strong stimulation group. The differences in the total effective rate between the light stimulation group and the moderate stimulation group, as well as the strong stimulation group, were statistically significant (both P<0.05). There was no significant difference in the total effective rate between the moderate stimulation group and the strong stimulation group (P>0.05). The total effective rate was 83.9％ in the dog-days acupoint application group, versus 45.4％ in the Magic Acupuncture Patch group, and there was a statistically significant difference between the two groups (P<0.05). Conclusion: The efficacy of dog-days acupoint application in the prevention and treatment of CB is better than that of Magic Acupuncture Patch; the degree of stimulation is the basis for the effect of dog-days acupoint application on prevention and treatment of CB, and the moderate and strong stimulations are more appropriate.
