OBJECTIVETo explore efficacy enhancing and detoxification roles of Jiedu Quyu Zishen Recipe (JQZR) in treating systemic lupus erythematosus (SLE) by studying its effect on Toll like receptor 9 (TLR9) signal pathway of murine macrophage cells after JQZR stimulated CpG oligodeoxynucletide (CpG ODN).
METHODSMurine macrophage cells in vitro cultured were randomly divided into 4 groups, i.e., the blank serum group, the CpG ODN stimulus group, the CpG ODN + dexamethasone group, the CpG ODN + medicated serum group. Murine macrophage cells were collected after 24-h intervention. The expression of TLR9, myeloid differentiation factor 88 (MyD88), NF-KB, IFN-α mRNA were analyzed by RT-PCR. The expression of TLR9 and NF-κB protein were analyzed by Western blot. Changes of the NF-KB transcriptional activity were assayed by Dual-Luciferase reporter assay system.
RESULTSmRNA expressions of TLR9, MyD88, NF-κB, and IFN-α, protein expressions of TLR9 and NF-κB, and NF-κB transcriptional activities were enhanced, showing statistical difference when compared with those of the blank serum group (P <0. 05, P <0. 01). Compared with the CpG ODN stimulus group, mRNA expressions of MyD88, NF-κB, and IFN-α, the protein expression of NF-κB and the NF-κB transcriptional activities decreased in the CpG ODN + dexamethasone group with statistical difference (P <0. 01). Compared with the CpG ODN stimulus group, mRNA expressions of TLR9, MyD88, NF-κB, and IFN-α, protein expressions of TLR9 and NF-κB, and NF-κB transcriptional activities were decreased in CpG ODN+ medicated serum group with statistical difference (P <0. 01).
CONCLUSIONEfficacy enhancing and detoxification roles of JQZR in treatment of SLE might be realized through regulating TLR9 signal pathways.

OBJECTIVETo compare the short-term clinical outcome between unilateral fixation fusion (ULF) and minimally invasive spine transforaminal lumbar interbody fusion (MIS-TLIF) in treating lumbar disc herniation (LDH).
METHODSThe clinical data of 39 patients with LDH were retrospectively analyzed from June 2008 to March 2013. There was 22 males and 17 females, aged from 45 to 75 years old with an average of 56.9 years. Therer were 3 cases in L3,4, 15 cases in L4,5, 21 cases in L5S1. Among them, 21 patients underwent unilateral fixation fusion (ULF group) and 18 underwent minimally invasive spine transforaminal lumbar interbody fusion (MIS-TLIF group). Operation time, blood loss, the times of radiographic exposure and hospital stay were noted and compared between two groups. Radiograph informations were regularily accessed and VAS, ODI scores were recorded at 3 days and 3, 6, 12 months after operation, respectively. According to modified Macnab criteria, the clinical effects were evaluated at final follow-up.
RESULTSAll operations were successful without severe complications. The averaged operative time and the times of radiographic exposure in ULF group [(95 ± 25) min and (4.2 ± 0.4) times] were less than that of MIS-TLIF group [(120 ± 35) min and (10.1 ± 3.9) times] (P < 0.05). But, the mean blood loss and hospital stay in MIS-TLIF group [(75 ± 45) ml and (7.2 ± 2.2)d ]were less than that of ULF group [(165 ± 60) ml and (11.0 ± 3.7) d] (P < 0.01). All patients were followed up from 12 to 45 months with an average of 29.5 months. The VAS and ODI score had significantly improved during the follow-up and no significant differences were found between two groups at the same time point (P > 0.05). The postoperative radiographs showed internal fixation position was good. And all patients obtained bone fusion by CT scan at 1 year after operation. There was no significant differences in modified Macnab criteria between two groups at the latest follow-up (P > 0.05).
CONCLUSIONFavorable short-term clinical effects can be achieved in suitable LDH patients with ULF or MIS-TLIF surgical procedures.

OBJECTIVETo study the clinical effect of combined treatment with gamma-globulin, corticosteroids, immunosuppressor and Chinese medicines on systemic lupus erythematosus (SLE) patients characterized by hypoplastic bone marrow (HBM).
METHODSNineteen patients were randomly assigned to two groups, the treated group (10 cases) received combined therapy of prednisone and cyclophosphamide (CTX) plus Chinese medicine Langchuang Recipe after being treated impactively with gamma-globulin. The control group (9 cases) was treated with prednisone and CTX. Changes of hypoplastic bone marrow, peripheral white blood cell (WBC), complement C3, 24 h urinary protein excretion, and lupus activity index (LAI) were observed, and a follow-up was carried out for one year.
RESULTSAfter one-month treatment, the bone marrow hypoplasia was relieved significantly in the treated group (P < 0.05, P < 0.01), showing an improvement superior to that in the control group (P < 0.05, P < 0.01); after three months treatment, the level of complement C3 increased (P < 0.01), while the 24 h urinary protein excretion and LAI decreased in the treated group (P < 0.05), showing significant difference as compared with those in the control group (P < 0.05, P < 0.01). In the follow-up period, 3 cases withdrew from the trial because of infection and 4 cases manifested full moon-face and acne in the control group, while no adverse reaction was found in the treated group.
CONCLUSIONTreatment with integrated Chinese and Western medicine could effectively improve bone marrow hypoplasia, alleviate the clinical symptoms, suppress the activity of lupus in patients, and reduce the adverse reaction of treatment, showing a superiority to the treatment with prednisone combining with CTX.

OBJECTIVETo investigate the effect of Jiangtang Yishen Recipe (JTYSR) on high insulin induced cell proliferation of human glomerular mesangial cells (HMCs) and the expression of insulin receptor substrate 1 (IRS-1) and phosphatidylinositol-3-kinase (PI-3K).
METHODSHMCs were divided into 4 groups, i.e., the negative control group, the high insulin model group, the JTYSR group, and the LY294002 group. The concentration of insulin, JTYSR, and LY294002 was respectively confirmed by pre-experiment. Different culture solution was respectively added for different groups. RPMI1640 culture solution was added for HMCs in the negative control group, while HMCs in the rest 3 groups were cultured by 100 nmol/L insulin for 24 h. Meanwhile, HMCs from the JTYSR group and the LY294002 group were exposed to 125 mg/L JTYSR and 80 micromol/L LY294002 respectively for further 48 h. The proliferation of HMCs was detected by MTT and flow cytometry. The protein expression of IRS-1 and PI-3K in HMC was detected by immunohistochemical assay and Western blot. Results The proliferation of HMCs induced by high insulin could be significantly lowered, and the protein expression of IRS-1 and PI-3K could be down-regulated in the JTYSR group and the LY294002 group (P <0.01). Compared with the LY294002 group, the protein expression of IRS-1 and PI-3K could be slightly down-regulated in the JTYSR group (P <0.05).
CONCLUSIONJTYSR could lower high insulin induced proliferation of HMCs, and its mechanism might be related to insulin signaling pathway.
