OBJECTIVETo observe the impacts of acupoint catgut embedding therapy and acupuncture-moxibustion therapy on the long-term efficacy and patient's life quality in the treatment of allergic rhinitis.

METHODSSixty-nine patients were randomized into the combined acupuncture-moxibustion and acupoint catgut embedding therapy group (combined therapy group, 36 cases) and an acupuncture-moxibustion group (33 cases). In the acupuncture-moxibustion group, acupuncture was applied at Yingxiang (LI 20), Shangyingxiang (EX-HN 8), Yintang (GV 29), Shangxing (GV 23), Tongtian (BL 7) and Zusanli (ST 36). Moxibustion was applied at Zusanli (ST 36), Feishu (BL 13), Dazhui (GV 14) and Fengmen (BL 12). In the combined therapy group, on the basis of the treatment as acupuncture-moxibustion group, the catgut embedding therapy was applied at Feishu (BL 13), Fengmen (BL 12), Pishu (BL 20), Shenshu (BL 23), Zhongwan (CV 12) and Qihai (CV 6). The treatment duration was 4 weeks in the two groups. The clinical efficacy of allergic rhinitis and rhinoconjunctivitis quality of life questionnaire (RQLQ) score were observed before and after treatment as well as in the 4-weeks follow-up after the end of treatment respectively.

RESULTSThe markedly effective rate was 72.7% (24/33) in the combined therapy group and 48.4% (15/31) in the acupuncture-moxibustion group after treatment. The efficacy was similar between the two groups (P > 0.05). It was 57.6% (19/33) in the combined therapy group and was 22. 6% (7/31) in the 4-week follow-up after treatment, indicating the long-term efficacy in the combined therapy group was superior to that in the acupuncture-moxibustion group (P<0. 05). Scores of RQLO after treatment and in 4-week follow-up after treatment in both groups were improved as compared with those before treatment (all P < 0.05). In 4-week follow-up, the improvements in sleep and affection in the combined therapy group were superior to the acupuncture-moxibustion group (3.27 +/- 3.23 vs 4.61 +/- 3.56, 3.48 +/- 3.67 vs 5.81 +/- 4.15, both P < 0.05).

CONCLUSIONThe acupoint catgut embedding therapy combined with acupuncture-moxibustion therapy are safe and effective in the treatment of allergic rhinitis and display the more roles in the long-term efficacy.

Objective To investigate the mRNA and protein expression levels of interferon(IFN)-?in the peripheral blood of patients with systemic lupus erythematosus(SLE),to analyze the relationship between IFN-?and disease activity,and to evaluate the role of IFN-?in the pathogenesis of lupus.Methods SYBR green dyeⅠbased real-time quantatives PCR method was used to compare the mRNA expression levels of IFN-?in the peripheral blood leucocyte of SLE patients and healthy controls.Surum levels of IFN-?were measured with ELISA method.Results IFNA1 mRNA expression level in SLE patients(2.8?3.5)was signifi- cantly lower than that of normal controls(12.7?10.7,P=0.000).There was no significant difference between patients treated with glucocorticoid and those without in the expression level of IFNA1(P=0.549).Serum levels of IFN-?in SLE patients was significantly higher than that of normal controls(P=0.003).The SLEDAI score and anti-dsDNA antibody correlated positively,and complement components C3,C4 and leukocytes correlated negatively with serum concentration of IFN-?.IFN-?level correlated with the presence of fever and rash. Conclusion The close relationship between IFN-?serum level and disease activity in SLE patients suggests that IFN-?might be of importance in the disease process.

OBJECTIVEApoptosis of the cells of liver cancer cell line HepG2 could be induced by TNF alpha and actinomycin D (Act D). In the current study, the molecular mechanism of the apoptosis protection of stronger neo-minophagen C (SNMC) to HepG2 cells was investigated.

METHODSSNMC was added to the HepG2 cell culture medium when the cell concentration reached 0, 2, 20, 100, 200, 800 microg/ml 30 min before their apoptosis were inducted with TNF alpha and Act D. A flow cytometry assay was performed to detect the cell apoptosis rate; electromicroscopy was employed to visualize the subcellular structure after apoptosis. DNA ladder formation was checked with genomic DNA agarose electrophoresis. The expression pattern of apoptosis related protein Caspase-3, Bcl-2 and Bax was detected by Western blot.

RESULTSAfter pretreatment with various concentrations of SNMC and 12 hours after treatment with TNF alpha and Act D, the HepG2 cell apoptosis rate and DNA ladder formation decreased dramatically when the SNMC concentration was higher in the media; the intracellular inactive form of Caspase-3 increased while the 17*10(3) active Caspase-3 decreased gradually. In addition, the expression of Bcl-2 increased and the expression of Bax decreased. Under the electromicroscope, the typical nucleolus condensation of HepG2 induced by TNF alpha and Act D was not seen among the 100 microg/ml SNMC treated cells.

CONCLUSIONSNMC inhibits TNF alpha and Act D induced HepG2 cell apoptosis. This protective action may be regulated by intracellular apoptosis related factors.

BACKGROUNDInflammatory mechanisms had played an important role in the occurrence and prognosis of acute myocardial infarction, inflammatory mediators was associated with adverse outcomes of acute myocardial infarction. This study tested the hypothesis that in the acute phase of myocardial infarction with ST-segment elevation, neutrophil count and high-sensitivity C-reactive protein are predictive of angiographic morphologic features that indicate thrombus formation in the infarct-related artery.

METHODSThis retrospective study included 182 consecutive patients with acute myocardial infarction and ST-segment elevation. Patients were assigned to a thrombus-formation group (n = 77) and a non-thrombus-formation group (n = 106). All patients had a Killip's classification

RESULTSThe levels of high-sensitivity C-reactive protein, total leukocyte counts, neutrophil counts, and neutrophil/ lymphocyte ratios were substantially higher in the thrombus-formation group than in the non-thrombus-formation group patients (for each, P < 0.05). Stepwise Logistic regression analyses identified high-sensitivity C-reactive protein, neutrophil count, and neutrophil/lymphocyte ratio as independent predictors of thrombus formation in the infarct-related artery (for each, P < 0.05).

CONCLUSIONSIn patients with acute myocardial infarction, higher neutrophil counts, neutrophil/lymphocyte ratio, and levels of high-sensitivity C-reactive protein are predictors to indicate thrombus formation.

OBJECTIVETo explore the crew and passengers' comfort on the Shijiazhuang-Taiyuan passenger dedicated line and physical factors, such as air pressure, noise, wind speed.

METHODSComfort investigation of all the crew (n = 244) and passengers (n = 377) on the Shijiazhuang-Taiyuan passenger dedicated line at speed of 250 km/h and 200 km/h and the detection of the air pressure, noise and wind speed were performed in 2011.

RESULTSSignificantly higher ratio of comfortable feeling, lower ratio of seriously discomfortable feeling were observed in crew and passengers at 200 km/h compared with those at 250 km/h (P < 0.05), as well as rapid disappearance of discomfortable feeling in crew (P < 0.05) and significantly higher ratio of lightly discomfortable feeling and lower ratios of tinnitus and eardrum discomfort induced by air pressure and noise in passengers at 200 km/h. No significant difference was observed in ear discomfort induced by air pressure and noise among crew, and the duration of disappearance of discomfortable feeling among passengers between 200 km/h and 250 km/h. The noise in carriages exceeded the related standard when the high-speed train passing through the tunnels.

CONCLUSIONThe individuals feel more comfortable at 200 km/h than 250 km/h in this line., which may be related with rapid variation of wind speed and noise when the train passes through the tunnels with high speed.

AIMTo study the effects of emodin on intracellular calcium concentration ([Ca2+]i) and L-type calcium current of the single ventricular myocytes from guinea pig.

METHODSEnzymatic dissociation was used to isolate single ventricular myocytes from adult guinea pig. They were loaded with Ca2(+)-sensitive fluorecent indicator Fluo-3/AM. [Ca2+]i represented by fluorescent intensity (FI) was measured by laser scanning confocal microscope. Whole cell patch clamp technique was used to record ICa-L.

RESULTSAt resting status, [Ca2+]i was not affected by emodin (1-100 mumol.L-1). Emodin at the concentration of 1 mumol.L-1 was shown to increase the [Ca2+]i induced by 60 mmol.L-1 KCl. The peak value of fluorescent intensity was increased from 1,877 +/- 551 to 2,905 +/- 739 (n = 8, P < 0.05). Emodin at the concentration of 10 mumol.L-1 had no effect on the increase of [Ca2+]i induced by 60 mmol.L-1 KCl. However, the increase of [Ca2+]i induced by KCl was reduced to 1,214 +/- 335 (n = 8, P < 0.05) by 100 mumol.L-1 emodin. The density of ICa-L was increased from (-6.2 +/- 1.3) pA/pF to (-8.3 +/- 0.3) pA/pF (n = 6, P < 0.05) by 1 mumol.L-1 emodin at the test pulse of 0 mV. The current was not altered by 10 mumol.L-1 emodin. But it was inhibited from (-6.6 +/- 1.0) pA/pF to (-3.80 +/- 0.16) pA/pF (n = 6, P < 0.05) by 100 mumol.L-1 emodin at the test pulse of +10 mV.

CONCLUSIONEmodin has two-way regulation on [Ca2+]i and ICa-L of cardiomyocytes in guinea pig.

OBJECTIVEThis study was designed to investigate the prevalence, clinical characteristics and outcome of upper respiratory infection (URI) caused by Mycoplasma pneumoniae (MP) in children.

METHODSPharyngeal cultures for MP antibody were performed in 960 children with acute URI. The samples were randomly collected from the outpatient room or emergency room (Observed group). Of the Observed group, there were 232 cases under 1 year of age, and the remainder, were between 1-12 years old. The samples from 100 healthy children aged from 6 months to 12 years were used as the Control group. The prevalence of MP infection between the two groups was compared. The clinical manifestations and the outcome between the patients with MP positive and negative were compared.

RESULTSMP antibody was positive in 31.7% (304/960) of the Observed group but only 9.0% (9/100) in the Control group (P < 0.05). The URI patients under 1 year of age had a lower positive rate of MP than those over 1 year old (P < 0.05). Coughs and tonsillitis were more common (P < 0.05), but catarrh, gastroenteritic symptoms, herpes, and tetter were rare (P < 0.01) in URI patients with MP positive compared with those with MP negative. Pneumonia developed in 14.8% of the patients with MP positive but only 7.0% in those with MP negative (P < 0.01).

CONCLUSIONSMP is one of the main pathogens of acute URI in children. Acute pharyngotonsillitis symptoms are predominately presented in children with MP infection. MP infection was commonly seen in children over 1 year old and they are prone to develop pneumonia.

OBJECTIVETo observe the early bone integration of oral implants after injection of exogenous nerve growth factor (NGF) and investigate the effects of NGF on peri-implant osseointegration.

METHODSTwelve New Zealand white rabbits were used in this study to establish bi-mandible implant model. Then local injection of 1 µg NGF was given on the right side of the mandible as experimental group and normal saline only was injected on the left side as control group once a day for seven days. The rabbits were respectively sacrificed at 2, 4 and 8 weeks after surgery. The implant-bone grinding samples were prepared and stained by toluidine blue for general observation, X-ray, histology and bone histomorphometry analysis.

RESULTSThe density of the new bone around implants at 2 and 4 weeks was lower than normal bone. Compared with the control group, the quantity of new bone and bone-implant contact ratio significantly increased in the experimental group. At 8 weeks, the new bone density in both groups was similar to the normal bone. In the experimental group, the haversian system was observed. Bone contact ratio was significantly different between experimental and control group at 2 and 4 weeks, but similar at 8 weeks.[control group at 2 weeks (26.67 ± 3.88)%, 4 weeks (52.59 ± 5.07)% and 8 weeks (97.33 ± 6.75)%, experimental group at 2 weeks (42.24 ± 6.67)%, 4 weeks (72.25 ± 6.30)% and 8 weeks (99.15 ± 4.68)%].

CONCLUSIONSApplying exogenous NGF in the early phase could accelerate the formation and maturation of trabecular bone around the implants and shorten the period of osseointegration. Nerve growth factor could promote osseointegration in the early stage of oral implantation.
