Objective To investigate the clinical efficacy of acupuncture combined with back Shu acupoint catgut embedding therapy in treating allergic rhinitis. Methods Totally 66 allergic rhinitis patients were included. Random number table method was used to divide the 66 patients into observation group and control group, with 33 cases in each group. The control group was given Ketotifen Fumarate Nasal Drops nose drops 2 drops each time, 3 times a day, Loratadine Tablets 10 mg orally, once a day for 4 weeks. The experimental group was treated with acupuncture, once a day, 10 d as a treatment course, three courses in total; at the same time, back Shu acupoint catgut embedding therapy was given, 15 d each time, twice treatment in total. After the end of treatment, clinical efficacy, clinical symptom score, life quality score, serum levels of inflammatory factors, serum immunoglobulin, peripheral blood eosinophil count and the incidence of adverse reactionsof the two groups were observed. Results The total effective rate was 93.94% (31/33) in observation group and 75.76% (25/33) in the control group, with statistical significance in the two groups (P<0.05). Compared with before treatment, the TNSS score, TNNSS score and RQLQ score of the two groups were significantly lower than after treatment (P<0.05); the IgE and EOS levels significantly decreased (P<0.05); the serum IL-17 and IL-22 levels were significantly lower (P<0.05). Compared with the control group, the TNSS, TNNSS and RQLQ score and the levels of IgE, EOS, IL-17 and IL-22 in the treatment group were lower after treatment (P<0.05). There was no significant difference in adverse reactions between the two groups (P>0.05). Conclusion Acupuncture combined with catgut embedding therapy in the treatment of allergic rhinitis has a significant clinical efficacy, which can improve the level of inflammatory factors in patients with high safety.

Objective To study the activation of Janus protein tyrosine kinase (JAK)/signal transducer and activator of transcription 1 (STAT1) signaling pathway and its inhibitor-signal transducer and activator of transcription-1(SOCS-1) in patients with systemic lupus erythematosus. Methods A total of 45 patients with active systemic lupus erythematosus (SLE) and 30 healthy controls were randomly selected. Western blot was performed to measure the expression of Stat1 protein and phospho-Stat1 protein (an activated form of Stat1 protein) in the monocytes after stimulation with recombinant high mobility group box1 (rHMGB1) at various time points. Expression of Stat1 protein in the skin or lesional skin was also detected. Phasic expressions of SOCS-1 mRNA in the monocytes after rHMGB1 stimulation were detected by real-time reverse transcription-polymerase chain reaction. SOCS-1 gene expression in the skin or lesional skin was also detected. Results The expression level of Stat1 proteins in the monocytes from patients with SLE was higher than that from healthy controls (t=9.16,P<0.01) and positively correlated with SLE disease activity index (SLEDAI) (r=0.59,P<0.01). Expression of phospho-Stat1 in the monocytes from SLE patients was time-dependently upregulated after stimulation with rHMGB1 at various time points, while expression of SOCS-1 mRNA remained unchanged(all P>0.05). Expressions of phospho-Stat1 protein and SOCS-1 mRNA in the monocytes from healthy controls were increased transiently after stimulation with rHMGB1(all P<0.05). Both expressions of phospho-Stat1 protein and SOCS-1 gene in the lesional skin from patients with SLE were upregulated compared with those in normal skin from healthy controls (all P<0.01). Conclusion There are hyperactivation of JAK-STAT1 signaling pathway and negative feedback down-regulation of SOCS-1 in patients with systemic lupus erythematosus. HMGB-1 may be partly involved in the pathogenesis of SLE by the abnormal mediating function of JAK-STAT1 signal transduction pathway.

3T3-L1 adipocytes were cultured with various concentrations of high-density lipoprotein ( HDL, 0, 10, 50, and 100 μg/ml ) for 16 h and with lipopolysaccharide ( LPS, 100 ng/ml ) for another 6 h. Interleukin-8 in the medium was determined by ELISA, and PPAR-γ mRNA expression by reverse transacription polymerase chain reaction (RT-PCR). Interleukin-8 levels were increased in LPS-treated cells ( P<0.05 ), but decreased in HDL-treated cells in the dose-dependent manner. PPARγ mRNA expressions were increased in HDL-treated groups than those treated only with LPS. These results suggested HDL may decrease interleukin-8 secretion via up-regulating PPARγ expression in adipocytes.

OBJECTIVETo investigate the clinical characteristics and GCH I gene mutations in patients with dopa-responsive dystonia (DRD).
METHODSThe clinical features of 3 families with 6 affected members and 8 sporadic cases were analyzed to determine the clinical characteristics, and 2 families with 4 affected members and 2 sporadic cases were screened for mutations of the GCH I gene.
RESULTSAge at onset was (10 +/- 3) years. Onset occurred earlier in female (9 +/- 4) years than in male (12 +/- 1) years. The initial symptom was a gait disorder, dystonia or tremor in most patients and nine patients (64%) presented with diurnal fluctuation. Thirteen patients (93%) were cured and one was improved after administration of low doses of levodopa for 3 months and no long-term side effects of levodopa had occurred. Two independent mutations were found in three patients. Gln161Pro, a new missense mutation, was found in a sporadic case, leading to a relatively severe phenotype. The two patients with mild phenotype in one family were found to have Lys224Arg mutation, as previously described.
CONCLUSIONSDRD patients have diverse phenotypes and diurnal fluctuation is an important feature. They have dramatic and sustained response to levodopa. There may be a correlation between genotype and phenotype. The detection of GCH I mutations is helpful in early diagnosis of non-typical cases.
