OBJECTIVETo observe interventional effects of anti-viral therapy and Compound Qin-gre Granule (CQG) on host cellular immune functions of acute virus infection patients.

METHODSThirty acute virus infection patients were recruited to detect peripheral lymphocyte subsets. They were randomly assigned to two groups, the Western medicine treatment group (treated with anti-virus Western medicine) and the integrative medicine treatment group (treated with anti-virus Western medicine plus CQG). T-cell subsets were re-examined 7 days later. Changes between before and after treatment were observed. Effect on host cellular immune functions and efficacy were compared between the Western medicine treatment and the integrative medicine treatment.

RESULTSCompared with the normal control group, the percentage of peripheral T cells increased, and the percentage of B/NK cells decreased in acute virus infection patients (P < 0.01). Meanwhile, in T cell subsets, the percentage of CD8+ T cells and CD8+ CD38+ T cells increased (P < 0.05, P < 0.01); and percentages of CD4+ T cells, CD4+ CD28 + T cells, and CD8+ CD28+ T cells decreased (P < 0.05, P < 0.01). After one-week treatment, percentages of CD4+ T cells, CD4+ CD28+ T cells, and CD8+ CD28+ T cells increased (P < 0.05, P < 0.01), while the percentage of CD8+ CD38+ T cells decreased (P < 0.01). More significantly, these changes were greater in the integrative medicine treatment group than in the Western medicine treatment group (P < 0.05).

CONCLUSIONSDisarranged cellular immune functions existed in acute virus infection patients. CQG could significantly improve viral infection induced immunologic derangement and immunologic injury.

OBJECTIVETo observe preventive and therapeutic effect of Yifei Jianpi Recipe (YJR) on chronic obstructive pulmonary disease (COPD) model rats and to explore its mechanism from the way of airway inflammation and airway mucus hypersecretion.

METHODSThe COPD rat model was established by using cigarette smoking combined with intratracheal injection of lipopolysaccharide (LPS). Male SD rats were randomly divided into the blank control group (control group), the model group, the YJR group, 6 in each group. Forced vital capacity (FVC), forced expiratory volume in 0. 1 second (FEV0. 1), FEVO. 1/FVC, peak expiratory flow (PEF) was tested by lung function device. Pathological changes of bronchi and lung tissues were observed by HE staining. Airway Goblet cells were observed using AB-PAS staining. Contents of IL-8, IL-17, and TNF-α in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay (ELISA). Protein expressions of intercellular cell adhesion molecule-1 (ICAM-1), nuclear factor KB (NF-KB), mucin 5AC (Muc5AC), and Toll-like receptor 4 (TLR4) in rat airway were detected by immunohistochemical assay. mRNA expressions of TLR4 and Muc5AC in bronchi and lung tissues were detected by real-time quantitative PCR (RT qPCR).

RESULTSChanges of bronchi and lung tissues in the model group rats were consistent with typical pathological manifestations of COPD. Compared with the model group, the degree of lung injury was significantly alleviated in the YJR group. Compared with the control group, FVC, FEV0. 1, FEVO. I/FVC, and PEF were decreased (P <0. 01), contents of IL-8, IL-17, and TNF-α in BALF were significantly increased (P <0. 01), protein expressions of ICAM-1, NF-KB, Muc5AC, and TLR4, mRNA expression levels of Muc5AC and TLR4 in bronchi and lung tissues were also significantly increased in the model group (P <0. 01). Compared with the model group, FVC, FEV0. 1, FEV0. 1/FVC, and PEF were significantly increased in the YJR group (P <0. 01, P <0. 05), but the rest indices were significantly lowered (P <0. 01, P <0. 05).

CONCLUSIONYJR could decrease contents of IL-8, IL-17, and TNF-α in BALF of COPD model rats, inhibit protein expression levels of ICAM-1, NF-κB, Muc5AC, and TLR4.in airway and lung tissues, thus playing preventive and therapeutic roles by reducing airway inflammation and airway mucus hypersecretion.

Objective To observe the improvement effects of Qingshen Granule on the life quality of chronic kidney disease (CKD) patients with damp-heat syndrome. Methods The CKD patients with damp-heat syndrome were randomly divided into experimental group and control group. The control group was treated with Western medicine, and the treatment group was treated with Qingshen Granules additionally for 12 weeks. SCr and eGFR were observed before and after treatment, and the life quality was investigated by KDQOL-SFTM1.3. Results Actually 156 cases were completed, including 77 cases in the treatment group and 79 cases in the control group. The total rate of curative effect was 81.82% (63/77) in teatment group, and (63.29%, 50/79) in control group, with significent difference (P<0.05). Multivariate linear regression analysis indicated that gender, education level, TCM syndrome score, CKD stage, eGFR and Hb level could affect the life quality. The scores of KDQOL-SFTM and its containing the MOS item short from health survey (SF-36) and kidney disease targeted areas (KDTA) were significantly improved after treatment in experimental group (P<0.05), while the scores in control group were with no significant improvement. The improving effects of PCS, and SPL, SLEEP, PS in KDTA in treatment group were significantly superior to those in control group (P<0.05). The scores of life quality in effective and stable cases increased significantly after treatment compared with before treatment (P<0.05). Conclusion Qingshen Granules can effectively improve the life quality of CKD patients with damp-heat syndrome, and the effect is not dependent on the improvement of laboratory indexes (renal function).

Objective To study the effect of zoledronate (ZOL) on Ca2+/calmodulin-dependent kinase Ⅱ δ (CaMK Ⅱ δ) and down-stream gene expressions during osteoclast differentiation.Methods Mouse osteoclast precursors RAW264.7 cells were divided into the control group and ZOL group.The cells in both groups were induced with 50μg/L receptor activator of nuclear factor kappa B ligand (RANKL) and were harvested on 5 d,while the cells in ZOL group were also simultaneously treated with 1 × 10-6 mol/L ZOL for 2 d.Five days later,the cells were harvested and examined osteoclastogenesis,as well as gene expressions of CaMK Ⅱ δ,nuclear factor of activated T-cells cytoplasmic 1 (NFATc1),tartrate-resistant acid phosphatase (TRAP) and cell-sarcoma receptor coactivator (c-Src).Results The number of TRAP positive multinuclear osteoclasts,number and size of dentin absorption lacunae and area in the ZOL group were (20.0±3.2),(18.0±4.2) and (6 335.3± 1 043.2)μm2 respectively,which were significantly lower than (36.0 ± 8.4),(37.2 ± 5.0) and (11 636.2 ± 3 661.1) μm2 in the control group and decreased by 44.4 ％,51.6 ％ and 45.6 ％ respectively (P＜0.01).ZOL also significantly inhibited the gene expressions of CaMK Ⅱ δ,NFATc1,TRAP and c-Src,and the mRNA levels of these genes were decreased by 44.1％,49.0％,53.8％ and 49.6％ respectively,the protein level were decreased by 43.5 ％,32.2 ％,45.5 ％ and 48.0 ％ respectively.The immunofluorescent cytochemistry detection results showed the fluorescence intensity of CaMK Ⅱ δ,NFATc1,TRAP and c-Srcin in the ZOL group was significantly weakened when compared with the control group.Conclusion ZOL could significantly inhibit the osteoclast formation and bone absorption function,and down-regulates gene expressions of CaMK Ⅱ δ,NFATc1,TRAP and c-Src in osteoclast differentiation.

Objective To investigate the effects of music therapy in treating cognitive dysfunction in early stroke patients. Methods Forty patients who had suffered a stroke in the previous four weeks were randomly di-vided into two groups of 20. One received music therapy as part of their cognitive training ( observation group) , and the other did not (control group). Before and after 6 weeks of treatment, cognitive functioning was evaluated using the second Chinese edition of Loewenstein's occupational therapy cognitive assessment (LOTCA). The patients' a-bility in the activities of daily living was also evaluated using the modified Barthel index (MBI). Results After treatment, the total LOTCA and MBI scores in both groups were significantly higher than before. Both LOTCA and MBI scores in the observation group were significantly higher than in the control group, and there were also signifi-cant differences between the observation and control groups on all of the LOTCA sub-items except spatial percep-tion. Conclusions Music therapy can improve the effects of rehabilitation on cognition and the ADL ability of early stroke patients.

Objective To study the role of protective antigen(PA)and N-terminal segment of lethal factor (LFn)in the entrance of EGFP(enhanced green fluorescent protein)into HeLa cells. Methods The DNA fragments encoding LFn and EGFP were amplified,respectively,and cloned into the plasmid pET-21 a(+)one after another to construct a recombinant plasmid pET-LFn-EGFP. The plasmid was txansformed into BL21 cells to express LFn-EGFP protein under the induction of IPTG. The protein was purified by Ni chelating chromatography. After incubation with LFn-EGFP in the presence of PA or not, the HeLa cells were analyzed by flow cytometry or laser confocal microscopy. Results The fusion protein LFn-EGFP was purified by over 90% homogeneity and retained the ability of LF to bind with PA when incubated with J774A.1 macrophage cells,and could get into HeLa cells. Conclusion The LFn-EGFP could enter the HeLa cells in a PA independent pathway. But PA could help more LFn-EGFP molecules enter into HeLa cells.

Objective To evaluate the clinical effect of absorbable self-enhancing cartilage nails in the treatment of radial head fractures.Methods Data of 22 patients with radial head fractures,who had undergone open reduction and internal fixation with absorbable self-enhancing cartilage nails from January 2008 to December 2011,were retrospectively analyzed.Among them,data of 18 patients were complete,including 10 males and 8 females.According to the Mason classification,there were 14 cases of Mason Ⅱ,3 cases of Mason Ⅲ and 1 case of Mason Ⅳ.Two patients were combined with radial neck fractures,9 with osteochondral fractures of capitellum,and 1 with posterior dislocation of the elbow and olecranon avulsion fracture.The radial head fractures were temporarily fixed with Kirschner wires after open reduction,then absorbable self-enhancing cartilage nails with length from 16 to 24 mm and diameters of 1.5 mm were applied to reach final fixation.The heads of nails were right underneath of cartilages without penetrating bone cortexes on the contralateral side.The radial neck fractures were reduced and fixed with T-plates or anatomical plates after the radial head fractures were fixed with cartilage nails.Four cases of osteochondral fracture of capitellum were fixed with absorbable sutures to external epicondyle of humerus.For other 5 cases of osteochondral fracture of capitellum,the bone fragments were removed due to too small to fix.Results All 18 patients were followed up for 6 to 54 months (average,31.3 months).All fractures achieved bone union,and the healing time ranged from 5 to 12 weeks (average,8.7 weeks).There were no complications,such as internal fixation failure,nonunion,hematoma,sinus formation,osteolytic changes of radial heads and so on.According to the Broberg-Morrey elbow performance score,13 cases were excellent,4 good,and 1 fair,with the total excellent and good rate of 94.44％ (17/18).At final follow-up,the elbow range of motion was 90° to 150° (average,123.8°),and the range of forearm rotation was 130° to 180° (average,152.5°).Conclusion Absorbable self-enhancing cartilage nails can be used to treat various kinds of radial head fractures,and the results are satisfactory.
