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 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.

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 evaluate the capacity of atopy patch test in diagnosis of food allergy in children with atopic dermatitis (AD).Methods Egg and milk,as the most common food allergens among Chinese children,were employed in this study.Skin prick test (SPT) and atopy patch test (APT) with fresh egg and milk were carried out in 68 children with AD.Oral food challenges in an open style were performed to confirm the diagnosis of food allergy.Resuits Of these patients,58(85.3%)were sensitive to egg,40(58.8%)to milk and 34(50.0%) to both.Of 98 patients with positive challenge,47 showed late response,10 immediate reactions.and 41 mixed reactions.The sensitivity,specificity,positive predictive value (PPV),negative predictive value (NPV) and the agreement with food challenges in diagnosis of egg/milk allergy were 96.6%/67.5%.90.0%/82.1%,98.2%/84.4%,81.8%/63.9% and 95.6%/73.5%,respectively for APT alone,37.9%/30.0%,100%/89.3%,100%/80.0%,21.7%/47.2% and 47.1%/54.4%,respectively for SPT alone.APT was found to be more sensitive in diagnosis of late-phase reactions than SPT (P<0.01).No significant difference was found in the sensitivity between APT alone and the combination of APT and SPT in parallel algorithm for diagnosis of egg or milk allergy (x2=0.509,0.549,both P>0.05) or in the specificity between APT alone and that in serial algorithm( P=1.000;x2=3.514,P>0.05).Conclusions APT is superior to SPT in diagnosis of late responses to food,and the combination of SPT and APT does not facilitate the diagnosis of food or milk allergy compared with APT alone.

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.

A research combined trickling filter system and active sludge aeration system was applied in the treatment of industrial wastewater from gas-generating with heavy oil. The wastewater contained both high contents of NH+4-N and mixed hydrocarbons including various PAHs. Its BOD5/COD ratio was less than 0.3 and belongs to recalcitrant, toxic wastewater. The results showed a touch-growth biofilms system was formed on the porous packing material and it played a key role in the decrease of toxicity of the influent. It could also improve the biodegradability of the wastewater.

By means of comparing biomasses of biodegradation fungi,Fusarium sp.HG-P-01 for ?-cypermethrin,a synthetic pyrethroid insecticide used widely in China,in five different media,the Czapek-Dox medium was selected as the best medium for mycelia growth.Furthermore,an experiment of central composite rotatable design(CCRD) was used to optimize the content of nutrient components.The optimal composition of C,N and P in media for HG-P-01 were 20.94 g/L,1.82 g/L and 1.66 g/L,respec-tively,in which an expectant or real rate of ?-cypermethrin-degradation got to 96.34% or 93.78% by HPLC for a concentration of 50 mg/L after 24 h treatment.The predicted value in degradation rate model was con-sistent with that from HPLC method.

Objective To assess the features of transcranial sonography (TCS) in Parkinson disease (PD) and Alzheimer disease (AD).Methods Totally 38 PD patients (PD group),28 AD patients (AD group) and 26 controls (control group)underwent TCS.The echogenicity of the substantia nigra,widths of third ventricle and parameters of middle cerebral artery among the three groups were analyzed.Results The ratio of hyperechogenicity of substantia nigra in PD group (31/38,81.58％) were higher than those in AD group (8/28,28.57％) and control group (3/26,11.54％;x2 =18.74,30.41,both P＜0.001),and there was no significant difference in hyperechogenicity of substantia nigra between AD group and control group (x2 =2.41,P=0.120).The widths of third ventricle in AD group ([0.82±0.14]cm) were wider than those in PD group ([0.63±±0.16]cm) and control group ([0.56±0.16]cm,both P＜0.001),and there was no significant difference in widths of third ventricle between PD group and control group (P=0.098).The mean velocities in bilateral middle cerebral artery in AD group were lower than that of in PD group and in control group (all P＜0.05).The pulsatility index in right middle cerebral artery in AD group were greater than that in PD group and control group (both P＜0.05).Conclusion According to the changes of echogenicity of substantia nigra,widths of third ventricle and parameters of middle cerebral artery,TCS may provide some useful information for diagnosis of PD and AD.
