Objective To explore the abnormal inflammatory cytokine profile of salpingitic infertility by means of cytometric bead assay(CBA). Methods To assay representative inflammatory cytokines of 40 patients of salpingitic infertility(PSI) and 40 healthy control by CBA, and compared 30 samples of serum with peritoneal fluid collected from identical subject. Results Experiment data displayed that in PSI the Th lymphocytes were decreased significantly (t =2. 1236,P <0. 05), Ts lymphocytes increased markedly, and the ratio of Th/Ts markedly decreased ( t = 2. 8392, P < 0. 01 ), compared with those of healthy control.(Pre-)inflammatory eytokines (IL-8, IL-1β, IL-6 and TNF-α) were all significantly higher than those of healthy controls ( t = 4. 9302,5. 5449,3. 4975,5. 6623, respectively, all P < 0. 01 ) ; while anti-inflammatory cytokines ( IL-10, IL-12 ), also increased markedly ( t = 5. 3428,5.9847, respectively, all P < 0. 01 ).Beside IL-10, all other cytokine concentrations presented in serum were higher than that of peritoneal fluid;IL-8(t =2.2113,P <0.05),IL-llS(t =2.9756,P <0.01), IL-6(t =2.3298,P <0.05), TNF-α (t =3. 2895, P < 0. 05 ), IL-12 ( t = 3. 3281, P < 0. 05 ), implying more sensitive of serum samples. Conclusion PSI displayed extensive disorders of the inflammatory cytokine network, CBA can be used to probe the disharmony condition at high through-out and high sensitivity.

Objective To explore the influence of intraventricular injection of 5, 7-drhydroxytryptamine (5, 7-DHT)in 5-HT1A receptor sensitivity of medial prefrontal cortex pyramidal neurons in the rats,and to clarity the effect of 5-HT1A receptor on the eletronic response of pyramidal neurons.Methods 36 male SD rats were randomly divided into sham operation group (n=21)and 5,7-DHT lesion group (n=15).5,7-DHT was injected intraventricularly in the rats in 5,7-DHT lesion group,and the same dose saline was injected in the rats in sham operation group.The rats in two groups were intravenously injected with different doses(0.5-128.0μg·kg-1 )of 8-CH-DPAT.The firing rate of mPFC pyramidal neurons was recorded with extracellular electrophysioological examination.The rats in two groups were intravenously injected with WAY100635,the sensitivites of the rats to 8-OH-DPAT and WAY100635 in 5, 7-DHT lesion group were observed, and compared with sham operation group.Results The different doses (0.5-128.0μg·L-1 )of 8-OH-DDAT had an excitatory-inhibitory effect on the firing rate of mPFC pyamidal neurons in sham operation group;the neurons were excited when the doses of 8-OH-DPAT were 0.5-38.0μg·kg-1 ,and the firing rates were increased(P<0.05);the neurons were inhibited when the dose of 8-OH-DPAT was 128.0μg·kg-1 ,and the firing rate was decreased.The different doses(0.5-218.0μg·L-1 )of 8-OH-DPAT inhibited the elecctronic response of pyramidal neurons of the rats in 5,7-DHT lesion group in a dose-dependent manner (df=5,F=3.44,P=0.003),and the firing rates were reduced. WAY-100635 (50μg·kg-1 )reversed completely the inhibition of 8-OH-DPAT.Conclusion The sensitivity of 5-HT1A receptor of rat mPFC pyramidal neurons can be decreased by intraventricular injection of 5,7-DHT.

BACKGROUND:Now it has cooperation and facilitative effete between myogenic regulatory factors through a long time study. So, gene therapy of double genes of Myod1 and Myog can obtain better effect, and can provide a new way for preventing denervated skeletal muscle atrophy.
OBJECTIVE:To construct eukaryotic co-expression vector carrying Myod1 and Myog genes.
METHODS:Ful-length Myod1 gene and Myog gene cDNA were amplified by reverse transcription PCR, and then inserted into pVAX1 vector after digested to establish the recombined Myod1 and Myog eukaryotic co-expression vector pVAX1-Myod1-IRES2-Myog-IRES2-EGFP, and then identified with gene sequencing. The in vitro cultured 3T3 cel s were transfected with pVAX1-Myod1-IRES2-Myog-IRES2-EGFP, and the expressions of Myod1 and Myog genes in the 3T3 cel s were detected with western blot assay in order to identify whether the 3T3 cel s could express the target protein correctly.
RESULTS AND CONCLUSION:The sequencing results showed that the sequence length and base sequence of Myod1 and Myog cDNA in eukaryotic co-expression vector pVAX1-Myod1-IRES2-Myog-IRES2-EGFP were identical with the reported sequences. Myod1 and Myog protein band expressions were detected in 3T3 cel s by western blot after transient transfection. The pVAX1-Myod1-IRES2-Myog-IRES2-EGFP, a eukaryotic co-expression vector of Myod1 gene and Myog gene is successful y constructed.

Objective To evaluate microdeletion of DAZ gene on the Y chromosome in patients suffering from idiopathic azoospermia or severe oligozoospermia.Methods The four sites including SY154,SY155,SY254,SY255 and SRY regions of Y chromosome in 38 cases of idiopathic azoospermia and severe oligozoospermia were detected by STS-PCR.Results Six cases of microdeletion of DAZ genes were found in 38 patiens,microdeletion rate was 15.8%.Five cases from 30 patiens suffering from idiopathic azoospermia,microdeletion rate was 16.7%.One case from 8 patients suffering from severe oligozoospermia had microdeletion.The microdeletion rate was 12.5%.Conclusions The microdeletion of DAZ gene is a major cause of idiopathic azoospermia and severe oligozoospermia leading to male infertility.Therefore,DAZ gene should be detected and PGD should be done prior to ICSI for the patients suffering from idiopathic azoospermia and severe oligozoospermia.

Objective To explore the correlations between septic acute kidney injury (SAKI) and immune condition and provide the clinical basis of predictable diagnosis and treatment in patients with SAKI.Methods Patients diagnosed with sepsis admitted to department of emergency intensive care unit of Peking Union Medical College Hospital between January 1st,2013 and September 30th,2014 were retrospectively studied.A total of 91 patients with sepsis were included,and they were divided into secondary immune deficient (SID) group (n =46) or control group (n =45).According to the diagnostic criteria and stage of the guidelines of Kidney Disease:Improving Global Outcomes 2012 (KDIGO-AKI 2012),patients in each group were divided into non-SAKI group (n1 =16,n2 =23)、KDIGO-1 group (n1 =15,n2 =13)、KDIGO-2 group (n1 =11,n2 =1) or KDIGO-3 group (n1 =4,n2 =8).The morbidity of each stage and the renal index along with the progression of SAKI was also compared in patients with SAKI in two groups.Results While there was a significant difference in the morbidity of KDIGO-2 (23.9% vs.2.2%,x2 =0.321,P =0.002) in patients with SAKI between immune deficient group and control group,the morbidity of KDIGO-1 and KDIGO-3 had no significant difference (KDIGO-1:32.6% vs.29.8%,x2 =0.040,P =0.701;KDIGO-3:8.7% vs.17.8%,x2 =-1.805,P =0.200).There was also no significant difference in the renal index (△Scr、△eGFR) and progression of SAKI (elapsed days from the diagnosis of sepsis to the occurance and most severe stage of SAKI) in patients with SAKI in two groups (P > 0.05).Conclusion There was no significant difference of the severity of septic acute kidney injury in patients with and without secondary immune deficiency.Inflammatory mediators-induced kidney injury in the process of immune response may not be the main mechanism in SAKI.

Objective To improve the understanding of primary pulmonary artery sarcoma(PAS)and its early diagnosis and treatment.Methods The clinical data of 3 PAS patients in Beijing Anzhen Hospital and related literature,the clinical features,diagnosis and therapy of the disease were retrospectively studied.Results Pulmonary artery sarcoma had similar clinical presentations to pulmonary thromboembolism(PTE).Although CT pulmonary angiography and Color Doppler echocardiography etc were helpful to the diagnosis of the entity,the confirmed diagnosis needed the operation.The surgery was main therapy for the disease.Conclusion Pulmonary artery sarcoma is easily misdiagnosed as PTE.The clinicians should pay more attention to the disease so as to early diagnose and treat it.
