Objective To investigate the therapeutic effect of the Hubei Wingnut ( Malus hapehensis ) leaf decoction (MHD) against conjunctivitis infected with human simplex virus type I (HSV-1). Methods Malus hupehcnsis decoction was used as the active treatment and ribavirin ( RBV) eye drop was used as the positive control. Both of the Vero cells and rabbit eye conjunctiva were infected with HSV-1. The effect and mechanism of the MHD on viral replication was determined by observing the cytopathic effect ( CPE) . The efficacy of MHD at different doses on the rabbit viral conjunctivitis was examined by pathological changes of eye conjunctiva tissues. Results MHD did not inhibit the proliferation of HSV-1 in vitro. The inflammatory reactions of rabbit viral conjunctivitis caused by HSV-1 were obviously attenuated or disappeared after treatment with MHD at 6 kg·L-1 and 3 kg·L-1 for 7 consecutive days,compared with the negative control of 0. 9% NaCl. The curative rate of MHD at the middle and high doses was 83. 3% and 100. 0%, respectively. Conclusion MHD has the potential for treating eye conjunctivitis caused by HSV-1 by relieving inflammation.

OBJECTIVETo evaluate the effectiveness of manual therapy and traction for lumbar disc herniation and analyze the current status of this kind of randomized clinical trial (RCT).
METHODSDatabase of CNKI, VIP, WANFANG, PubMed and OVID were searched. Some relevant journals were manually retrieved. A total of 2 874 literatures on manual therapy and traction for lumbar disc herniation were collected, of which 17 articles met the inclusion criteria. The Jadad score scale was used to evaluate the quality,and RevMan5.0 was used for meta-analysis of literatures.
RESULTSThe results of the meta-analysis of all trials involved were as followed:the combined effect of the effective rate was RR = 1.10, 95% CI [1.06, 1.14], the combined effect of the cure rate was RR = 1.36, 95% CI [1.21,1.52], the combined effect of the VAS was RR = 1.37, 95% CI [1.28, 1.45], the combined effect of the JOA was RR = 4.75, 95% CI [4.40, 5.09].
CONCLUSIONThe overall quality of the current RCT researches about manual therapy for lumbar disc herniation was lower,and did not support the conclusion that manual therapy was more effective than traction for lumbar disc herniation.

The effects of mangiferin on uric acid excretion, kidney function and related renal transporters were investigated in hyperuricemic mice induced by potassium oxonate. Mice were divided into normal control group, and 5 hyperuricemic groups with model control, 50, 100, and 200 mg x kg(-1) mangiferin, and 5 mg x kg(-1) allopurinol. Mice were administered by gavage once daily with 250 mg x kg(-1) potassium oxonate for seven consecutive days to create the model. And 3 doses of mangiferin were orally initiated on the day 1 h after potassium oxonate was given, separately. Serum uric acid, creatinine and urea nitrogon levels, as well as urinary uric acid creatinine levels were measured. Mouse uromodulin (mUMOD) levels in serum, urine and kidney were determined by ELISA method. The mRNA and protein levels of related renal transporters were assayed by RT-PCR and Western blotting methods, respectively. Compared to model group, mangiferin significantly reduced serum uric acid, creatinine and urea nitrogon levels, increased 24 h uric acid and creatinine excretion, and fractional excretion of uric acid in hyperuricemic mice, exhibiting uric acid excretion enhancement and kidney function improvement. Mangiferin was found to down-regulate mRNA and protein levels of urate transporter 1 (mURAT1) and glucose transporter 9 (mGLUT9), as well as up-regulate organic anion transporter 1 (mOAT1) in the kidney of hyperuricemic mice. These findings suggested that mangiferin might enhance uric acid excretion and in turn reduce serum uric acid level through the decrease of uric acid reabsorption and the increase of uric acid secretion in hyperuricemic mice. Moreover, mangiferin remarkably up-regulated expression levels of renal organic cation and carnitine transporters (mOCT1, mOCT2, mOCTN1 and mOCTN2), increased urine mUMOD levels, as well as decreased serum and kidney mUMOD levels in hyperuricemic mice, which might be involved in mangiferin-mediated renal protective action.

Objective To explore the expression of HCK gene during the cardiomyocyte differentiation of mouse embryonic stem cells and analyze the role of HCK gene in maintenance of pluripotency of embryonic stem cells.Methods Mouse embryonic stem cells were cultured,then induced to differentiate into cardiomyocytes.Total RNAs were isolated from mouse embryonic stem cells in the differentiation days:0 day(D0),the second day(D2),the fourth day(D4),the sixth day(D6),the eighth day(D8),respectively.The levels of HCK mRNAs were assessed by the method of semi-quantitive reverse transcriptase-polymerase chain reaction(RT-PCR).In the meanwhile,Total proteins were also isolated from mouse embryonic stem cells in the differentiation D0,D2,D4,D6,D8,and the levels of HCK proteins were evaluated by Western-blot.Results HCK mRNAs could be detected in the mouse embryonic stem cells in D0 and D2,however,they were undetectable from D4 to D8.The expression of HCK mRNAs was rapidly down-regulated during cardiomyocyte differentiation of mouse embryonic stem cells.Expression of HCK proteins,which coincided with HCK mRNAs,down-regulated during differentiation and couldn't be detected in D4.Conclusions With the cardiomyocyte differentiation of mouse embryonic stem cells,the expression of HCK in the levels of mRNA and proteins are sharply down-regulated;HCK may play an important role in maintaining the pluripotency of embryonic stem cell.

The megakaryocyte and platelet lineage may be one of the major sites of human cytomegalovirus (HCMV) infection. However, whether HCMV aggravates apoptosis in normal megakaryocytes was not well investigated. Megakaryocytic cell line CHRF-288-11 and HCMV AD 169 strain were co-cultured in this study. PCR was used to detect the direct infection of the cells by HCMV IEA expression. The apoptotic cells were analyzed by morphologic observation, DNA ladder formation, annexin V/PI and PI assay with flow cytometry. The results showed that HCMV significantly inhibited the growth of CHRF cells in three different concentrations of viral infection groups (10(-3), 10(-2), 10(-1)). The viability levels in each infection groups were 77%, 73% and 68% respectively after incubation for 7 days, compared with 98% in the control group. Using annexin V/PI with flow cytometry, it was shown that the percentages of apoptotic cells viral infection in groups (10(-3), 10(-2), 10(-1)) were (21.3 +/- 2.49)%, (25.8 +/- 3.65)% and (31.4 +/- 3.91)% at 7 days after infection, while the control was (3.68 +/- 1.47)%. The apoptotic cells were further confirmed by morphologic observation and DNA ladder formation. Furthermore, PCR detection also showed the direct infection by identification of HCMV IEA expression in CHRF cells. This study suggested that HCMV could directly infect megakaryocytes and aggravated apoptosis in HCMV-infected megakaryocytes.

OBJECTIVETo investigate the changes in natural killer (NK) cell count in the peripheral blood of asthmatic patients.
METHODSThe number of NK cells in the peripheral blood was determined with flow cytometry in 63 asthmatic patients with acute episodes, 65 patients with stable asthma and 62 healthy nonatopic subjects.
RESULTSA significant decrease in NK cell number was noted in asthmatic patients during acute exacerbation [(13.9-/+9.4) %] in comparison with patients with stable asthma [(22.5-/+12.3) %] and healthy subjects [(19.6-/+10.1)%] (P<0.05), and the NK cell number showed no significant difference between the latter two groups (P>0.05).
CONCLUSIONNK cell number is reduced in acute exacerbation of asthma, suggesting its important role in the asthmatic process.
