Objective:To investigate the expression of chemokine receptor in eupotic and ectopic endometrial tissues of women with endometriosis, and in endometrium of women without endometriosis.Methods:Normal endometrium, eutopic endometrium and endometriotic tissues were obtained from patients with endometriosis at laparoscopy. Total RNA was then extracted using the TRIzol reagent. The expression of chemokine receptors in these tissues were analyzed by way of semi-quantitative reverse transcriptase-polymerase chain reaction.Results:Compared to normal endometrium, the eutopic endometrium expressed significantly more CCR6, CCR8, CCR9 and CX3CR1(P

OBJECTIVETo improve the diagnosis and treatment of penile metastasis from rectal carcinoma.

METHODSWe reported a case of penile metastasis secondary to rectal adenocarcinoma, reviewed the relevant literature, and discussed the common origins, clinical features, pathogenic mechanisms, diagnosis and treatment of this disease.

RESULTSThe patient was a 54-year-old male, with metastatic penile tumors secondary to rectal adenocarcinoma, with serious adhesion to the surrounding tissue and metastasis to the liver. As treatment, we performed colostomy to relieve voiding difficulty, followed by combination chemotherapy with oxaliplatin, 5-fluorouracil, and levofolinate. The patient died 10 months later as a result of systemic failure.

CONCLUSIONPenile metastatic malignancy has a poor prognosis. Early diagnosis and combined and individualized therapies may improve the quality of life, relieve pain and prolong the life of the patient.

Objective To evaluate the significance of human interleukin-31(IL-31)in the pathogenesis of atopic dermatitis and its correlation with pruritus in patients with atopic dermatitis(AD).Methods Twenty-two children with mild to severe atopic dermatitis and 22 age-matched healthy controls were included in this study.Patients and controls were randomly and equally assigned into stimulation and non-stimulation groups.Venous blood samples were obtained from all participants,peripheral blood mononuclear cells were isolated from these samples and cultured with(stimulation groups)or without(non-stimulation groups)staphylococcal enterotoxin B(SEB)for 24 hours.Then,the mRNA expression of IL-31 on PBMCs was assessed via real-time reverse transcription-PCR.ELISA was used to detect the total serum IgE level in these objects.The severity of AD in patients was rated according to scoring atopic dermatitis(SCORAD).The relationship between the mRNA expression of IL-31 and the level of serum total IgE.severity of atopic dermatitis,and degree of pruritus.was evaluated.Results The expression of IL-31 mRNA on non-stimulated PBMCs from patients was 23.2 folds as high as that from the healthy controls(P＜0.01).The stimulation with SEB upregulated the mRNA expression of IL-31 on PBMCs.and the increase on PBMCs from patients was 20.44 times of that from the controls.The total serum IgE level was 260.05 IU/mL(5.9-1131.01 IU/mL)and 17.7 IU/mL(5-140.7 IU/mL)in the Patients and controls respectively(P＜0.01).There was no significant correlation between the mRNA expression of IL-31 and disease severity or total serum IgE level(r=0.07.0.22respectively.both P＞0.05)in patients witll AD.Condusions IL.3 1 is involved in t11e pathogenesis of AD,which is unlikely to be IgE-dependent.SEB can induce the rapid expression of IL-31 on PBMCs of healthy human,and is an important modulator for the production of IL-31.

Objective To investigate the feasibility of labeling mice spleen lymphocytes with superparamagnetic iron oxide(SPIO)and in vitro MR imaging of the labeled cells.Methods Spleen lymphocytes of 5 mice were isolated and then labeled with SPIO of 100,50,25,15,10,5 μg/ml,which was previously prepared with PLL.Prussian blue staining was performed to show the intracellular iron.Cell viability was compared among fresh,labeled and unlabeled cells.Different concentrations of mice spleen lymphocytes were screened using 3.0 T MR on T2WI,T2 * WI and SWI sequences in vitro.Cell viability was compared using independent-sample t test between groups.The MRI values among different groups were compared using one-way ANOVA.Results SPIO prepared with PLL could successfully label mice spleen lymphocytes,the optimum concentration of SPIO was 5 μg/ml.The Prussian blue staining showed intracellular blue spots and a labeling efficiency of(93.6 ± 2.1)％.Three groups of fresh,labeled and unlabeled cells showed a Trypan blue staining result of(94.8 ± 3.1)％,(88.7 ± 2.7)％,and(88.9 ±3.2)％,respectively; no statistically significant difference was found in cell viability between labeled and unlabeled lymphocytes(t =0.281,P ＞ 0.05); however,the cell viability of fresh cells were statistically significant higher than the labeled and unlabeled lymphocytes(t =8.125 and 7.253 respectively,P ＜0.05for all).Among the T2 WI,T2 * WI and SWI sequences under the same concentrations of cells,the SWI sequence was the most sensitive.Conclusions The mice spleen lymphocytes can be effectively labeled with SPIO with no impact on cell viability,and MR can be used to track these labeled cells in vitro.The SWI sequence is the most sensitive.

OBJECTIVETo observe the effect of total flavonoids of Oldenlendia difflusa (FOD) on NF-kappaB and IL-8, TNF-alpha, IL-10 expressions of ulcerative colitis (UC) model rats, and explore its immunological mechanism of anti-UC.

METHODSixty Kunming male mice with the average weight of (20 +/- 2) g were randomly divided into six groups. The control group (cont) was orally administered with distilled water. Whereas the remaining five groups were fed with 4% dextran sulphate sodium (DSS) solution for seven days to induce acute UC, and orally administered with the following drugs: distilled water (for the DSS group), SASP at dose of 500 mg x kg(-1) x d(-1) for the DSS + SASP group, FOD at dose of 60 mg x kg(-1) x d(-1) for the DSS + FOD-H group, FOD at dose of 40 mg x kg(-1) x d(-1) for the DSS + FOD-M group, and FOD at dose of 26.7 mg x kg(-1) x d(-1) for the DSS + FOD-L group. During the modeling and drug administration, the mice were scored for DAI. Seven days later, the mice were put to death, and their colonic tissue samples were collected to evaluate colonic mucosal lesions. The NF-kappaB p65, IL-8, TNF-alpha, IL-10 expressions were tested by immunohistochemical staining and ELISA.

RESULTSeven-day feeding with 4% DSS solution could successfully induce acute UC in mice. Compared with the cont group, the DSS group showed significantly higher DAI and colonic mucosal lesions, remarkable increase in NF-kappaB p65, IL-8, TNF-alpha expression in colonic tissues, and notable decrease in IL-10 expression (P < 0.05). FOD could prevent acute UC in mice included by DSS. Seven-day administration of 60 mg x kg(-1) x d(-1) or 40 mg x kg(-1) x d(-1) FOD could completely or partially resist the above mentioned changes caused by DSS. Compared with the DSS group, the DSS + FOD-H group and the DSS + FOD-M group showed reduction in colonic mucosal lesions, down-regulation in IL-8, TNF-alpha and NF-kappaB p65 expressions and up-regulation in IL-10 expression (P < 0.05).

CONCLUSIONFOD could significantly resist UC in mice. Its mechanism may be related to the inhibition of NF-kappaB p65 activation, the reduction of IL-8 and TNF-alpha expressions and the increase in the anti-inflammatory factor IL-10.

OBJECTIVETo investigate the clinical effect and safety of chiropractic in treating cervicogenic sudden hearing loss.

METHODSFrom January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.

RESULTSAfter the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).

CONCLUSIONCompared with routine method for cervicogenic sudden hearing loss, additional chiropractic can improve hearing and relieve neck pain effectively.

Objective To explore the similarities and differences between finger photoplethysmogram (PPG) and CSI in monitoring the depth of anaesthesia in Chinese adults under general anaesthesia. Methods Ninety-three patients, ASA ⅠorⅡ, aged 20-67, under general anaesthesia were enrolled. Anaesthesia was induced with target-controlled infusion (TCI) of propofol. The initial TCI concentration of propofol was set at 0.5 mg·L-1 followed by increments of 0.5 mg·L-1 at 3-min interval until the score of Modified Observer's Assessment of Alertness/Sedation Scale (MOAAS)reached 0. PPG and CSI were continuously monitored and their values were recorded every 2-4 seconds. MOAAS was recorded every 30 seconds to evaluate the sedation level in the study period. ResultsFor the periodfrom pre-induction to pre-intubation, the difference of photoplethysmogram amplitudevalues had statistical significance between level 4 and level 3, level 3 and level 2 of MOAAS (P<0.05). CSIvalues declined along with the decrease of MOAAS levels and were statistically different between every two neighboring levels of MOAAS (P < 0.05). Photoplethysmogram amplitude (PPGA) and pulse beat interval (PBI) values showed significant differences before and after intubation, pre- and post-incision (P < 0.05). Conclusions PPGA and PBI appear to be suitable to monitor the nociceptive component of balanced general anesthesia , while the CSI exhibits a good performance in monitoring the sedation or hypnotic component of balanced general anesthesia , thusthe combination of PPGA and CSI would benefit the monitoring of the adequacy of depth of anaesthesia.

Objective To investigate the effects of Saikosaponin A (SSA)on cognitive function and cAMP/CREB signaling pathway and expression of BDNF in mice after traumatic brain injury. Methods Sixty SD male mice were randomized into three groups:shame operation group (group S, n =20),trauma group (group T,n =20)and SSA treatment group (group A,n =20).Mice received an administration of SSA 5 mg/kg (group A)or equal volume saline (group S,group T)immediately and once daily for 5 consecutive days after trauma.The cognitive function was detected by Morris wa-ter maze test on day 1,3,7 and 14 after trauma.The hippocampal tissues were harvested after be-havioral tests and homogenized for measuring the levels of brain derived neurophic factor (BDNF)and cyclic AMP (cAMP)by ELISA as well as the levels of cAMP-response element binding protein (CREB)and phosphorylation-cAMP-response element binding protein (pCREB)by western bolt. Results Compared with group S,the escape latency and swimming distance were significantly pro-longed in group T on day 1,3,7 and 14 and group A on day 1,3 after trauma (P <0.05 );while compared with group T,they were significantly shorter in group A on day 7,14 after trauma (P <0.05).Compared with group S,the levels of BDNF,cAMP,CREB and pCREB were significantly de-creased in group T(P < 0.05 ).Compared with group T,the levels of BDNF,cAMP,CREB and pCREB were significantly increased in group A (P <0.05).Conclusion SSA can significantly improve cognitive dysfunction in mice after traumatic brain injury,and the mechanism may be related to the activation of cAMP/CREB signaling pathway and up-regulation of BDNF.
