Neutralizing antibodies are recognized to be one of the essential elements of the adaptive immune response that must be induced by an effective vaccine against HIV. However, only a limited number of antibodies have been identified to neutralize a broad range of primary isolates of HIV-1 and attempts to induce such antibodies by immunization were unsuccessful. The difficulties to generate such antibodies are mainly due to intrinsic properties of HIV-1 envelope spikes, such as high sequence diversity, heavy glycosylation, and inducible and transient nature of certain epitopes. In vitro neutralizing antibodies are identified using "conventional" neutralization assay which uses phytohemagglutinin (PHA)-stimulated human PBMCs as target cells. Thus, in essence the assay evaluates HIV-1 replication in CD4+ T cells. Recently, several laboratories including us demonstrated that some monoclonal antibodies and HIV-1-specific polyclonal IgG purified from patient sera, although they do not have neutralizing activity when tested by the "conventional" neutralization assay, do exhibit potent and broad neutralizing activity in "unconventional" ways. The neutralizing activity of these antibodies and IgG fractions is acquired through post-translational modifications, through opsonization of virus particles into macrophages and immature dendritic cells (iDCs), or through expression of antibodies on the surface of HIV-1-susceptible cells. This review will focus on recent findings of this area and point out their potential applications in the development of preventive strategies against HIV.

BACKGROUND:There are many methods for dental impression disinfection, including ultraviolet disinfection method, spraying, immerses disinfection method, argon plasma jet and radio frequency glow discharge on the argon gas ionization disinfection method. At present, there is stil lack of studies addressing the disinfection effect after gargling with mouthwash.
OBJECTIVE:To detect the kil ing effect on bacteria and fungi from the dental impressions, which are taken after gargling with cetylpyridinium chloride gargle and stable chlorine dioxide gargle, respectively.
METHODS:One hundred patients were randomly divided into cetylpyridinium chloride gargle group and stable chlorine dioxide gargle group. They were told to gargle with clean water for 1 minute, and then impressions were taken to remove the models with sterile cotton swab sampling in neutralizing agent which were sent to laboratory for bacteria and fungi culture. After 1 hour, the patients were asked to gargle with the different mouthwashes for 1 minute again, and then sterile cotton swab sampling was done at the same position for bacteria and fungi culture. The number of colonies was recorded, and the kil ing effects on kil ing bacteria and fungi on the surface of the impressions before and after gargling with different mouthwashes were observed.
RESULTS AND CONCLUSION:The number of bacteria and fungi before gargal had no significance difference before gargling. After gargling, the number of bacteria and fungi on the model was significantly lower than before (P<0.001). Two groups did not appear with any adverse reactions, and patients felt refreshed and comfortable after gargling with mouthwash. To gargle with mouthwash before taking impressions can control the number of bacteria and fungi on the samples effectively, thereby achieving the aim of control ing the mutual infections between the doctor and the patients effectively.

Objective To analyze the clinical features and interval of multiple primary carcinoma (MPC). Methods 52 patients with MPCs between October 2002 and May 2007 were reviewed. Results 7 patients had synchronous carcinoma (13.46%), and 45 had metachronous carcinoma (86.54%). The interval between the first primary cancer and MPC was from 0 to 31 years, averaged 7.1 years. Male was 7.3 years, and female was 9.3 years (P

Objective: To explore the heat injury level of vocal cord by different power of the Diomed 25 semi conductor laser so as to provide scientific evidence for clinical laser therapy of larynx diseases. Methods: Canine was used. The power of laser was set on 5, 10 and 20 W respectively, and the time of laser exposure was fixed on 2 s.When canine vocal cord was hit by laser in vivo , the depth and width of the tissue heat injury were measured. Results: When laser hit with 5, 10 and 20 W for 2 s exposure time, the corresponding depth of the tissue heat injury were 0.2 0.4,0.4 0.6,0.8 1.0 mm respectively, the corresponding width of the tissue heat injury were 1.0 1.7,1.7 2.0,2.0 2.6 mm respectively. There was significant difference between the tissue heat injury levels caused by different laser power under the same exposure time( P

This study is to compare the influence of CYP2D6 *3 and *4 genotypes and phenotypes on the metabolic activity of CYP2D6 in Chinese Han, Uygur and Kazakh ethnic groups. Allele specific amplification (ASA) was used to determine the CYP2D6*3 and CYP2D6*4 genotypes. Phenotypes of CYP2D6 in all subjects were determined using dextromethorphan as probe drug by HPLC methods. Among the 132 Han subjects, one subject (0.76%) exhibited the *1/*3 combination, and one (0.76%) exhibited the *1/*4. Among the 136 Uygur subjects, 4 subjects (2.94%) showed the *1/*3 combination, 12 (8.82%) showed *1/*4, 4 (2.94%) showed *4/*4, and one (0.74%) showed *3/*4. Among the 116 Kazakh subjects, 2 (1.72%) exhibited the *1/*3 combination, 7 (6.03%) exhibited *1/1*4, and one (0.86%) showed *4/*4. This research revealed significant differences in the occurrence frequencies of the CYP2D6 genotype between Han and Uygur ethnic groups, as well as between Uygur and Kazakh populations. However, no difference was found between Han and Kazakh populations. In addition, the prevalence of PMs of the Uygur is comparable to that of the Caucasians. However, the molecular mechanism underlying the poor metabolism is different in these two populations.
