Objective To study the mRNA expression of HS1-associated protein X-1(Hax-1),an an- ti-apoptosis genc,in the peripheral blood mononuclear cells(PBMC)of patients with systemic lupus erythe- matosus(SLE),and further investigate the roles and significance of Hax-1 in the pathogenesis of SLE.Meth- ods Generation of longer cDNA fragments from serial analysis of gene expression(SAGE)tags for gene identi- fication(GLGI)was applied to identify the gene Hax-1 according to the Long SAGE tag.Then reverse tran- scription-polymerase chain reaction(RT-PCR)technique was used to semiquantitatively analyze mRNA ex- pressions of Hax-1 in PBMC from 34 active SLE patients and 25 healthy subjects.Results Compared with healthy controls,there was significant difference between SLE patients in the active stage and the normal controls(Z=-4.556,P＜0.01).The average level of mRNA expression in active SLE group was higher than that in healthy controls.Significant difference was found between the group with mild SLE and either the moderate or the severe one(P＜0.01).Conclusion The mRNA expression level of Hax-1 in active SLE group increase markedly,and to some extent,it is related to the activity of SLE.This provides a valuable basis for the further study on the role of apoptosis in SLE.

OBJECTIVE: To determine the prevalence of depression and anxiety in patients with psoriatic arthritis (PsA), to investigate whether there is a difference in the prevalence of depression and anxiety between PsA and rheumatoid arthritis (RA) patients and to identify associated risk factors for depression and anxiety in PsA patients. METHODS: PsA and RA patients who visited Department of Rheumatology and Clinical Immunology in Peking University First Hospital from May 2018 to Sep 2019 were recruited. Self-rating anxiety scale and self-rating depression scale were surveyed and compared between PsA and RA patients. Demographics and clinical features including age, gender, disease duration, disease activity score, psoriasis area and severity index (PASI), and medical application were collected. Power Doppler and grey-scale ultrasound of joints, tenosynovitis and enthesis were performed. Multivariate Logistic regression was used to identify the factors associated with mood disorders and the odds ratio of depression and anxiety between the PsA and RA patients. RESULTS: Among the 114 enrolled PsA patients, 37 (32.5%) had mood disorders, in which 36 (31.6%) with depression and 15 (13.2%) with anxiety. Compared with 201 RA patients, PsA patients showed greater odds for depression [adjusted OR (95%CI): 2.7 (1.1-6.4)]. Depression was more often observed in the PsA than in the RA patients (31.6% vs. 18.9%, P=0.011). The similar trend for anxiety was also observed, although the difference was insignificant (13.2% vs. 8.5%, P=0.185). Age (OR=0.95, P=0.008), psoriasis duration (OR=0.94, P=0.018), pain visual analogue scale (OR=1.47, P=0.011), PASI score (OR=1.07, P=0.007) and presence of ultrasound enthesitis (OR=4.13, P=0.009) were identified as factors associated with depression in the PsA patients. PASI score (OR=1.07, P=0.001) was identified as associated factor for anxiety in the PsA patients. CONCLUSION The prevalence of depression and anxiety is elevated in PsA patients. Depression is significantly more prevalent in PsA patients than in RA patients. Younger age, shorter psoriasis duration, worse pain and presence of ultrasound enthesitis are associated with depression, while severe psoriasis rash is associated with both depression and anxiety in PsA patients.

The paper aimed to elucidate the specific impact of supramolecular chemistry on the Chinese medicine theories (CMT) in their modernization, after had summarized up the research status of supramolecular chemistry and analyzed the possible supramolecular forms of Chinese medicine (CM), as well as considered the problems in modernization of CM theories. On comparison of the classical chemistry that delt with chemical bonds among atoms, the supramolecular chemistry was rather concerned with varietes of weak noncovalent bonds intermolecules, and reflected the macro-apparent chemical properties of each molecules, and was the most appropriate chemical theories to explain the CMT and microcosmic materials. The molecules in the human body and Chinese material medica (CMM) formed supramolecules by way of self-assembly, self-organization, self-recognition and self-replication, with themselves or with complexation, composition, chelation, inclusion, neutralization etc. Meridian and Zang-fu viscera in CMT might be a space channel structure continuously consisted of unique molecules cavity that was imprinted with the supramolecularly template inside and outside of cells, through which the molecules in CMM interacted with the meridian and Zang-fu viscera. When small molecules in human body imprinted with macromolecules in meridian and Zang-fu viscera, in other words, they migrated along within imprinting channels of meridian and Zang-fu viscera on behavior of "Qi chromatography" impulsed by the heart beat, finally showed up on macroscopic the anisotropy of tissue and organ, as described namely as visceral manifestation in Chinese medical science. When small molecules in CMM interacted with imprinting channel on meridian and Zang-fu viscera, the natural properties and efficacy regularities of CMM was reflected on macroscopic. Therefore, the special representation forms of basic CMT is based on the macroscopic expression of "Qi chromatography" abided by imprinting effect regularities, and on whether the imprinted template of small molecules matched with cavity template of macromolecules in meridian and Zang-fu viscera, only is the adequate representation of supramolecular chemistry for them. The CMM materials is the mixture including single molecules and supramolecules. The compatibility for CM prescriptions can significantly change the function rules. Therefore in the study of basic CMT, we should pay special attention to the laws of supramolecular chemistry. It is the most essential differences of the CMT from the modern medicine which established by the laws of single molecular theories.

OBJECTIVETo develop a reliable assay for simultaneous sequence-based typing (SBT) of HLA-DPA1 and HLA-DPB1, and to apply it for the study of allelic polymorphisms in southern Chinese Han population.

METHODSBased on full-length HLA-DPA1 and HLA-DPB1 allelic sequences, locus-specific PCR primers were designed and applied to amplify the target sequence encompassing the entire exon 2 of HLA-DPA1 and HLA-DPB1. PCR products were purified with magnetic beads, and run through an ABI 3730 DNA sequencer. Genotypes were assigned with an Assign 3.5 SBT software.

RESULTSThe target sequences of HLA-DPA1 and HLA-DPB1 were both amplified with the PCR procedure. Little background and noise was observed in the derived sequences. Among 176 non-related healthy individuals, 4 HLA-DPA1 alleles with the frequencies of DPA1*02:02 (0.589) > DPA1*01:03 (0.284) > DPA1*02:01 (0.096) > DPA1*04:01 (0.031) were identified. In addition, 14 HLA-DPB1 alleles, including 4 common alleles (with a frequency of more than 5%, namely DPB1*05:01, DPB1*02:01, DPB1*04:01 and DPB1*02:02), 7 alleles with a frequency ranging from 1%-5% and 3 alleles with a frequency of less than 1% were identified. The results of HLA-DPB1 genotyping were all in accordance with the typing results derived from an Atria AlleleSEQR HLA-DPB1 kit.

CONCLUSIONA reliable technique has been established for simultaneous genotyping of HLA-DPA1 and HLA-DPB1, which may have a broad application in population and disease association studies.

OBJECTIVETo observe targeted expression of recombinant lentivirus-mediated (Lv)-hTERTp-TK and Lv-hTERTp-tumstatin in HepG2 cells, and explore the inhibitory effect of their combination on HepG2 cells both in vitro and in vivo.

METHODSLv-hTERTp-TK and Lv-hTERTptumstatin were used to infect HepG2 and L02 cells at different MOIs. Transfection efficiency was observed by fluorescence microscopy. Expression of TK and tumstatin mRNA was detected by reverse-transcriptase PCR. Proliferation and apoptosis were detected by MTT and flow cytometry, respectively. The HepG2 cells were examined by real time-PCR and western blotting to determine expression level of bcl-2 and VEGF mRNA and protein.A murine hepatocellular carcinoma model was established by injecting 1 * 10(7) HepG2 cells into 30 BALB/c nude mice. The modeled mice were randomly divided into a control group, mock group, Lv-hTERTp-tumstatin group, Lv-hTERTp-TK group, and combination group for four weeks of injections at regular intervals of PBS, Lv-hTERTp-null, Lv-hTERTp-tumstatin, Lv-hTERTp-TK, and Lv-hTERTp-tumstatin plus Lv-hTERTp-TK, respectively.Changes in tumor volume and weight, and cell morphology of tumor and major organs, were assessed by hematoxylin-eosin staining.Microvascular density of tumor tissue and cell apoptosis were assessed by immunohistochemical and TUNEL staining, respectively.

RESULTSThe Lv-infected HepG2 cells, and not the Lv-infected L02 cells, expressed TK and tumstatin. Lv-hTERTp-TK and Lv-hTERTp-tumstatin, alone or in combination, inhibited proliferation and increased apoptosis of the HepG2 cells, but the combination was more effective than either alone (P less than 0.05). None of the treatments affected proliferation or apoptosis of the L02 cells (P more than 0.05). The combination also led to a greater reduction of bcl-2 and VEGF than either alone (all, P less than 0.05). Tumor growth was significantly inhibited by the combination (P less than 0.05). In vivo, the combination treatment induced the greatest amount of apoptosis of the HepG2 cells. Cell morphology of major organs such as liver, spleen and kidney were similar to the control group. The combination also produced the most significant effect on tumor microvascular density (P less than 0.05) and the highest apoptosis index (P less than 0.05).

CONCLUSIONThe HTERT promoter can induce targeted expression of TK and tumstatin in HepG2 cells. Lv-hTERTp-TK combined with Lv-hTERTp-tumstatin can significantly inhibit proliferation and induce apoptosis of human HepG2 cells in vitro and in vivo, which may be related to down-regulation ofbcl-2 and VEGF.
