Objective To study the relationship between arousal and sleep apnea in old people with sleep apnea syndrome(SAS). Methods Sixty-two aged patients were diagnosed of SAS after polysomnography (PSG). Records included total sleep time, apnea-hypopnea index(AHI),total arousal number(TAN), arousal index(AI), total respiratory-related arousal number(TRAN), total number of arousal lasted over 15 seconds (T15AN) and the severity of hypoxemia (desaturation). Sixty-four non-aged patients were included in control group. Ten aged patients were intervened with nasal continuous positive airway pressure (nCPAP) treatment. Data were compared with that before treatment. Results The results for the above parameters of the aged and the non-aged SAS patients were( 35.1?23.2)/h and (39.1?27.2)/h respectively for AHI, (15.8?11.4)/h and (20.4?13.0)/h for AI, 44.1% and 51.3% for the ratio of TRAN/TAN, only 6.1% and 6.7% for ratio of T15AN/TAN. 50% of 62 aged and 64 non- aged SAS patients were in severe desaturation. The AI and TRAN of the aged patients were significantly lower than that of non-aged patients (P

To monitor the trans-differentiation from adult stem cells to germ cells, we analyzed the vasa expression of goat testicular tissues in different ages and constructed the germ cell specific reporting vector pVASA-EGFP. The expression of vasa was verified by RT-PCR and immunofluorescence. The vector pVASA-EGFP was constructed by molecular technology, then transfected into goat bone mesenchymal stem cells (BMSCs) by Lipofectamine 2000. Moreover, we observed the expression of the vector through green fluorescent protein (GFP). Immunofluorescence results show that Vasa was expressed in all groups of goat testicular tissues, RT-PCR results show that the levels of vasa mRNA in 3-month group and 10-month group were significantly higher than that in 10-day group. Sequencing and restriction enzyme results show that the vector was successfully constructed. After transfection and RA treatment, GFP expression was observed, which proved the validity of our reporting system. All the results proved that vasa was expressed in different ages in goat testicular tissues, and the vector pVASA-EGFP is efficient in monitoring the trans-differentiation in vitro, which paves the way for further characterization and screening of the trans-differentiation of goat BMSCs.

Objective To investigate hepatitis B virus (HBV) mother-to-child transmission rate in hepatitis B virus surface antigen (HBsAg)-positive pregnant women.MethodsA total of 1355 HBsAg-positive pregnant women and their 1360 newborns (included 5 twins)were collected prospectively.All newborns received hepatitis B immunoglobulin (HBIG) 200 U intramuscularly within 6 hours of birth as early as possible,and were administered with routine 10 μg recombinant hepatitis B vaccine (at 0,1,6 months of birth).The venous blood HBV markers and HBV DNA levels were detected in all newborns at 0,7,12 months of age.The measurement data were analyzed by t test.Qualitative data were analyzed by chi square test,rank sum test or Fisher exact test.Results The intrauterine HBV infection rate of 1360 infants were 1.54％ (21/1360) during 12 months of follow-up.The rate of intrauterine infection in HBeAg positive mothers was significant higher than that of HBeAg negative mothers (4.44％ vs 0,χ2 =35.99; P＜0.05); the rate of intrauterine infection in HBV DNA positive mothers was significant higher than that of HBV DNA negativemothers (3.13％ vs 0,χ2 =21.84; P＜0.05).When maternal serum HBV DNA≥1 × 107 IU/mL,the rate of intrauterine infection was 6.01 ％,which was significantly higher than that of maternal serum HBV DNA＜ 1 × 107 IU/mL (χ2 =39.43,P＜0.05).ConclusionsAfter strict combined active-passive immunization,the rate of HBV intrauterine infection is 1.54％.When mothers are HBeAg positive or with high level of HBV DNA,the rate of HBV intrauterine infection increases significantly.Intrauterine infection is the main cause of failure in immunoblockade of HBV mother-to-child transmission.

Objective To analyze the clinical features,and prognosis of the interstitial lung disease (ILD) in patients with dermatomyositis (DM) and polymyositis (PM) by chest X-ray,chest high-resolution CT scan (HRCT) and pulmonary lung function.Methods Thirty-three patients hospitalized with DM/PM associated ILD were retrospectively analyzed.Results Thirty-three patients with ILD were confirmed by HRCT.Abnormal pulmonary function tests were available in 82% of patients.Clinical-imaging analysis revealed that the pathological features of ILD were non-specific interstitial pneumonia (NSIP,57%) and unusual interstitial pneumonia (UIP,25%).UIP types showed a poor prognosis and high mortality (70%).Conclusion This study shows that HRCT is more sensitive for the diagnosis of ILD than lung function tests and chest X-ray.Combined HRCT and chest X-ray with lung function tests and blood gas analysis have shown that the major pathological types of ILD are NSIP and UIP,in which UIP are associated with high mortality and poor prognosis.

Serum TGF ? 1, fasting blood glucose(FBG), HbA 1c ,BUN,Cr,Ccr,lipidemia were detected in all cases. RESULTS: Serum TGF ? 1 in NA, MA and ODN groups [(35.02?6.70) ?g/L, (39.31?5.35) ?g/L, (58.58?9.56) ?g/L, respectively] was higher than that in control [(23.95?8.01) ?g/L, P

Objective: To observe the influence of epidermal growth factor tyrosine kinase inhibitors (EGFR-TKIs) on peripheral blood T lymphocyte subsets, and its efficacy and safety in the treatment of non-small cell lung cancer (NSCLC) patients.Methods: A total of 35 cases with NSCLC in our hospital were selected as the observation group and 28 healthy persons undergoing health examination at the same time were used as the control group.All the NSCLC patients were with EGFR mutations and accepted the EGFR-TKIs therapy.Flow cytometry was employed to detect T lymphocyte subsets in peripherial blood (including CD3+,CD4+,CD8+,CD4+/CD8+ and NK lymphocy-tes)in one week before the treatment, at the 1st, 2nd and 4th cycle after the EGFR-TKIs treatment, and the curative effect and safety were evaluated as well.Results: Before the chemotherapy, the levels of CD3+, CD4+, CD4+/CD8+ and NK lymphocytes in the NSCLC patients were significantly lower than those in the control group (P<0.01), and CD8+ lymphocytes increased significantly (P<0.01).After the treatment of 1, 2 and 4 cycles, the levels of CD4+and CD4+/CD8+ increased in varying degrees when compared with those before the treatment (P<0.01), and CD8+ decreased significantly when compared with that before the treatment (P<0.01).After the treatment of 2 and 4 cycles, NK cells increased in varying degrees when compared with those before the treatment (P<0.05).After the treatment of 4 cycles, the level of CD3+lymphocytes was significantly higher than that before the treatment (P<0.05).The T lymphocyte immune function in the patients with different therapeutic effects showed statistically significant difference (P<0.05).The order of lymphocyte subgroup improvement was PR>SD>PD.The adverse reactions caused by EGFR-TKIs were slight, and all could be improved markedly after the symptomatic treatment.Conclusion: EGFR-TKIs can significantly regulate the expression of T lymphocyte subsets in NSCLC patients and improve the immune function of the patients with promising safety.

Cycloheximide (CHX) inhibits protein synthesis in most eukaryotic cells and it is a well-known tool commonly used in biochemical research. In this paper, the antiviral spectrum of CHX against several DNA and RNA viruses have been evaluated. CHX showed strong inhibitory activities against several RNA viruses such as HIV-1, influenza viruses, coxsackie B virus, enterovirus (EV71) and several DNA viruses such as HSV and HCMV. Especially the strong inhibitory activities of CHX against coxsackie B virus and enterovirus caught our attention, since effective drugs available in clinic are limited. The SAR of CHX derivatives also has been discussed in the paper. The hydroxyl group at C-2' and carbonyl group at C-2" of CHX are essential for its antiviral activity. And modification to these groups results its derivatives' antiviral activities reduced or lost.

AIM: To prepare Nano-Liposome encapsulated MAGE3/HSP70(NL M3H) and study its character and antitumor immunity in mouse. METHODS: NL M3H was prepared by the thin film-dispersion ultrasonic. The shape and size of NL M3H were detected by electron microscope. The encapsulation rate, drug-carrying capacity, stability and the releasing character were tested by Sephedex-G100 gel filtration. The mouse was immunized by NL M3H, and the antitumor immunity was detected by ELISPOT and LDH release assay. RESULTS: The mean size of NL M3H was lower than 100 nm. The encapsulation rate was 38％.The drug content was 0.038 g/L. NL M3H has good stability after stored in 4℃ for 6 months. The releasing profile showed that 74 percent of proteins was released during the first 24 hours in saline. The results of ELISPOT and LDH release assay showed that NL M3H generated tumor specific cytotoxic T lymphocyte(CTL)to damage tumor cel1. CONCLUSION: NL M3H has novel characters, it can generate specific CTL to kill tumor cell, and can be used as new kind of vaccine agsinst tumor.
