OBJECTIVE: To screen the anti-tumor fraction of ethanol extracts from Thymus quinquecostatus Celak and investigate its anti-tumor effect on human leukemia cell line. METHODS: Ethyl acetate, n-butanol and acetone fractions were separated from the ethanol extracts of wild Thymus quinquecostatus Celak. Growth inhibiting effects of these extracts on human leukemia cell lines K562 and HL-60 were determined by live cell counting and cell growth curve analysis. The possible anti-tumor mechanism was studied by morphological analysis with norcantharidin as a positive control. RESULTS: Ethyl acetate fraction could significantly inhibit the proliferations of K562 and HL-60 cells, and the inhibiting effect depended on the concentration of ethyl acetate fraction. Ethyl acetate fraction could induce apoptosis of K562 and HL-60 cells. The n-butanol and acetone fractions had no significant inhibiting effect on K562 and HL-60 cells. CONCLUSION: Ethyl acetate fraction is the major anti-tumor fraction in ethanol extracts from Thymus quinquecostatus Celak.

OBJECTIVE: To study the anti-tumor and immunological effect of extracts from Thymus quinquecostatus Celak on mice transplanted S180 tumor cells. METHODS: Different doses of volatile oil and alcohol extracted substances from Thymus quinquecostatus Celak were given to mice bearing S180 tumor for 9 days. Tumor inhibition rates and coefficients of spleen and thymus were determined. RESULTS: Tumor inhibition rates of the groups with alcohol extracts (40 g crude drug.kg(-1).d(-1) and 20 g crude drug.kg(-1).d(-1)) were 51.5% (P<0.01) and 36.4% (P<0.05) respectively, and those of the groups with volatile oil (40 g crude drug.kg(-1).d(-1) and 20 g crude drug.kg(-1).d(-1))were both 39.4% (P<0.05). CONCLUSION: The extracts from Thymus quinquecostatus Celak have anti-tumor activities. The coefficient of spleen in group with alcohol extracts (40 g crude drug.kg(-1).d(-1))was close to normal value, and its coefficient of thymus was between that of the negative control group and the group with cyclophosphamide (0.02 g.kg(-1).d(-1)). The anti-tumor activity of the alcohol extracts was significantly higher than that of the control group and the tumor inhibition rate was depending on drug concentration. Depending on index of immunity,the extracts from Thymus quinquecostatus Celak may have some influences on immunity.

Objective To investigate the relationship between cognitive impairment and SH2 domain-containing inositol phosphatase-1 (SHIP-1) induced by hippocampal neuritis in intrauterine infected mice.Methods Thirty C57BL/6 female mice and 15 male mice were caged in a ratio of 2 ∶ 1.After that,the pregnant mice were divided into 2 groups.A mice model of intrauterine infection was established that intrauterine infection group (lipopolysaccharides,LPS group) induced by LPS at the concentration of 350 μg/kg and control group treated with same volume of saline (9 g/L).At 3 days postpartum,15 mice in each group were killed for hippocampus,and the protein levels of SHIP-1,nuclear factor-κB(NF-κB) p65 and phosphorus NF-κB(NF-κBp) in the hippocampus of the newborn mice were detected by Western blott,while the levels of interleukin 1β (IL-1β) and tumor necrosis factor (TNF-α)were detected by using enzyme linked immunosoobent assay.When the remaining mice were 8 weeks old(10 in each group),Morris water maze experiments were performed respectively,which the mice were tested for evaluating learning and memory function by positioning navigation and space exploration experiments.Results The expression of SHIP-1 was significantly increased in control group (0.677 ± 0.074) compared with LPS group (0.317 ± 0.095,t =2.984,P =0.041),while the levels of NF-κB p65,and NF-κBp,were significantly lower in control group (0.630 ± 0.109,0.352 ± 0.084) than LPS group(0.630 ± 0.109,0.352 ± 0.084) (t =3.516,5.161,P =0.025,0.007).Moreover,LPS significantly enhanced the expression of IL-1β and TNF-α [(5.875 ± 0.349) pg/mg,(14.256 ± 0.784)pg/mg] compared with control group[(1.621 ± 0.151) pg/mg,(3.984 ± 0.255) pg/mg],and the differences were significant(t =11.190,12.460,P=0.000,0.000).By the average Escape Latency tests for6 days,LPS group [at 1-6 days (58.286±1.418) s,(56.036 ±2.252) s,(55.071 ±1.856) s,(50.071 ±3.251) s,(52.893 ±2.372) s,(46.929 ±3.761) s] markedly impaired the learning capacity compared with the control group[(53.679 ±2.413) s,(47.571 ±3.529) s,(54.071 ±2.777) s,(47.250 ±2.864) s,(45.107 ±3.447) s,(42.393 ±3.463) s],and the difference was significant (F =4.466,P =0.001).Concurrently,in probe trains LPS group increased the time of in zone southeast latency to first [(44.080 ± 6.313) s] compared with the control group [(25.900 ± 6.033) s],while shortened the period of in zone platform duration and in zone SE duration [(0.000 ± 0.040) s,(4.000 ± 1.693) s],decreased the times of in zone SE frequency and in zone platform frequency[(0.100 ±0.100) times,(1.000 ±0.394)times] compared with the control group [(0.400 ± 0.202) s,(14.360 ± 5.000) s,(0.600 ± 0.267) times,(3.400 ±0.763) times] (t=2.082,1.746,1.962,2.794,1.756,P=0.026,0.049,0.033,0.006,0.048).Conclusion The expression of SHIP-1 in hippocampus of newborn mice with intrauterine infection is decreased,and the inhibitory effect of SHIP-1 on the expression of downstream pro-inflammatory cytokines NF-κB,inflammatory cytokines IL-1β and TNF-α is decreased,along with cognitive impairments.

OBJECTIVETo analyse the severity of chronic sinusitis osteitis and the correlation factors by global osteitis scoring scale(GOSS).

METHODSThree hundreds and thirty-four patients with chronic rhinosinusitis with or without nasal polyps(CRSwNP/CRSsNP) were enrolled prospectively in a large tertiary referral center. Preoperative sinus CT was analysed by PHILIPS MxLiteView software.Using grading and classification of GOSS, the association between GOSS and gender, age, smoking, CRS course, asthma, skin prick test(SPT), aspirin sensitive asthma (ASA), nasal polyp, Lund-Mackay, Lund-Kennedy, the number of previous sinus surgeries was examined.Finally a marker factors of severity of CRS osteitis was concluded.

RESULTSThere was no association between CRS osteitis and gender(P = 0.542), age(P = 0.092), smoking(P = 0.695), SPT(P = 0.182). Multiple liner regression analysis showed that there was no association between CRS osteitis and nasal polyps, ASA and asthma (all P > 0.05). The severity of CRS osteitis was correlated with the number of previous sinus surgeries, Lund-Mackay scores, Lund-Kennedy scores, CRS course (r1 = 0.528, r2 = 0.170, r3 = 0.193, r4 = 0.146, respectively, all P < 0.01).

CONCLUSIONSOsteitis is an important reason of refractory chronic rhinosinusitis. The number of previous sinus surgeries can be used as an important marker for the severity of the osteitis.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

OBJECTIVETo evaluate the impact of nasal function after Draf III frontal sinus surgery (Draf III) or the modified endoscopic Lothrop procedure (EMLP).

METHODSIt was a prospective study with self-control. The pre-operative clinical data of 30 patients (from 2010 to 2013, Beijing Tongren Hospital) who underwent Draf III surgery, with the testing results of T&T olfactory testing, acoustic rhinometry and rhinomanometry before and 1 year after operation in these patients were collected in this study. All patients complete visual analogue scale (VAS), a telephone follow-up questionnaire of olfactory function used by Wormald and Lund-Kenndy endoscopy score simultaneously with testings above. Most of 30 patients were chronic rhinosinusitis (CRS) with recurrent nasal polyps or systemic risk factors like asthma and aspirin-intolerance, called refractory rhinosinusitis. SPSS 19.0 software was used to analyze the data.

RESULTS89.3% (25/28) of these patients improved in nasal obstruction 1 year after operation, and the cure rats was 57.1% (16/28, VAS = 0). The level of improvement in nasal obstruction was significantly correlated with pre-operative nasal obstruction severity (r = 0.909, P < 0.01). 76.7% (23/30) improved in olfactory function 1 year after operation in all 30 patients, and 88.2% improved in patients with nasal polyps (CRSwNP). It was also found that olfactory function 1 year after operation was significantly related to Lund-Kennedy endoscopy scores (r = 0.671, P < 0.01), but was not correlated with VAS scores of nasal obstruction (P = 0.349).

CONCLUSIONThe Draf III frontal sinus surgery has a significantly positive effect on olfactory and ventilation function post-operatively, especially on refractory rhinosinusitis.
