Objective To analyze, the risk factors and related psychological factors in patients with gastroesophageal reflux disease (GERD)and survey the curative effect. Methods All of 200 outpatients with GERD(GERD group) and 200 healthy persons (control group)from January 2006 to January 2008 were randomly selected, and the personal data were investigated. The GERD questionnaire (RDQ) and the Zung-self-rating depression scale (SDS) test were used. Results In GERD group, the proportions of high education, city living, marriage instability ,heavy working pressure, high body mass index (BMI),smoking and drinking habit, peptic disease in family, using nonsteroidal anti-inflammatory drugs (NSAIDs) were higher than those in control group (Pall < 0.01). After treatment, the patients in GERD group had lower scores in the RDQ and SDS test than those before treatment (P< 0.01). Conclusions There are many risk factors in patients with GERD, especially the psychological factors. The therapy of GERD should combine with psy-chotherapy and avoid high BMI, smoking, drinking and overusing the NSAID.

OBJECTIVE: To compare the content of gastrodine in wild and cultivated Gastrodia elata from different habitats in Guizhou province in order to provide scientific reference for cultivation of G.elata.METHODS: Samples were extracted from G.elata with microwave.RP-HPLC method was used to determine the content of gastrodine in G.elata.RESULTS: The content of gastrodine in wild G.elata was higher than that in cultivated G.elata.The contents of gastrodine in wild G.elata were different from one another while the contents of gastrodine in cultivated G.elata hadn’t obvious differences.CONCLUSION: The quality of wild G.elata is superior to that of cultivated G.elata.The study provide scientific basis for the cultivation of G.elata.

To select appropriate descriptors for response of the patient-reported outcome (PRO) scale for the main symptoms of patients with chronic obstructive pulmonary disease (COPD) complicated with pulmonary heart disease.

Objective To investigates factors affecting the positive rate of blocking antibody treated by paternal lymphocyte immunotherapy in patients with recurrent spontaneous abortion (RSA).Methods From January 2008 to August 2012,326 RSA cases undergoing treatment in Infertility Center of Qilu Hospital were studied retrospectively.Those patients were divided into 2 groups randomly:260 cases in intradermal injection group were administered via bilateral forearm intradermal injections for immunotherapy once 21 days,then the blocking antibody was determined after 2 (23 cases),3 (73 cases),4 (74 cases),5(90 cases) times respectively,while in subcutaneous injection group,the 66 cases were administered via subcutaneous injection once 21 days,the blocking antibody measured after 3 times; In both cases,the blocking antibody was all determined 2 weeks later.The positive rate of blocking antibodies and the rate of successful pregnancy was recorded,and then followed up after the blocking antibody turning positive.Results (1)Positive rate of blocking antibodies:the positive rate of blocking antibodies were 17％ (4/23),58％ (42/73),72％ (53/74) and 84％ (76/90) in the 2,3,4,and 5 times of intradermal injection group,respectively (P ＜ 0.05).In subcutaneous injection group,the positive rate of blocking antibodies was 38 ％ (25/66),which was significantly lower than that in group intradermal injection receiving 3 times immunotherapy (P ＜0.05).(2) The rate of pregnancy:the 176 patients out of 200 patients were pregnant when antibody was positive after immunotherapy,with 71.6％ (126/176)of patients gained successful pregnancy(the length of pregnancy more than 5 months).Conclusions The route and frequency of administration of immunotherapy could influence the positive rate of blocking antibody.The rate of successful pregnancy will be increased after blocking antibody turning positive.

Background and purpose: High expression of telomerase and telomere stability are two common features in tumor cell. hTERT is a catalytic subunit of telomerase, TRF2 is extremely important to maintain the length and stability of telomerase. This study was to construct the recombinant adenovirus mediated shRNA to hTERT and TRF2, and to investigate the inhibitory effects of the vector by solo-inhibiting and connect-inhibiting in the MCF-7 cells, in order to present a new approach to the gene therapy for breast cancer. Methods: rAd-hTERT and rAd-TRF2 were constructed and the expression of hTERT mRNA and TRF2 mRNA were tested by FQ-PCR 48 hours after transfecting in MCF-7 cells. Apoptosis was observed by flow cytometry 1 to 6 days after transfection. Results: ①At 48 hours after transfection, the results of FQ-PCR showed that compared to PBS group, the expression of hTERT in rAd-hTERT group was obviously decreased and the inhibition ratio was about 86%, but TRF2 had not been obviously inhibited (P>0.05);the expression of TRF2 in rAd-TRF2 group was obviously decreased and the inhibition ratio was about 80%, but hTERT had not been obviously inhibited (P>0.05);in rAd-hTERT/rAd-TRF2 group, the inhibition ratio of hTERT and TRF2 were about 88% and 85%. Comparing rAd-hTERT/rAd-TRF2 group with rAd-hTERT group and rAd-TRF2 group, there were no significant differences of inhibition ratio between hTERT gene and TRF2 gene(P>0.05). Otherwise, comparing rAd-HK group, rAd-blank group with PBS group, there were no significant differences of inhibition ratio between hTERT gene and TRF2 gene(P>0.05). ②The result of flow cytometry showed that apoptosis was induced at the first day after transfecting in rAd-hTERT group and rAd-TRF2 group, the most obvious apoptosis was in the 3rd to 5th days,at the peak in the 5th day, and decreased in the 6th day after transfection. The apoptosis ratio of rAd-hTERT group was 46.2%, rAd-TRF2 group was 43.5%. The apoptosis ratio of rAd-hTERT/rAd-TRF2 group was 46.2% at first day, 68.5% at the second day, the most obvious apoptosis was in the 3rd to 6th days and was 77.6% in the 6th days in rAd-hTERT/rAd-TRF2 group. There were significant differences in apoptosis ratio in solo-inhibiting and connect-inhibiting(P<0.05). In addition, comparing rAd-HK group, rAd-blank group with PBS group, there were no significant differences in apoptosis ratio(P>0.05). Conclusion: ①Target sequence of RNAi which aimed at hTERT gene and TRF2 gene was designed efficiently, and the RNAi expression vectors were seen in vivo study efficiently and specifically inhibited the correspond gene expression and promoted cell apoptosis in MCF-7 cells. ②rAd-hTERT vector and rAd-TRF2 vector have no synergistical effect and antagoinstical effect on inhibiting hTERT gene and TRF2 gene mRNA expressing in MCF-7, but there was synergistical effect in terms of the induction of apoptosis. So association-RNAi-technique targeting to the genes of telomere length and stability can effectively promote tumor cell into apoptosis and inhibit breast cancer cell growth. RNAi technique of connecting correlation genes is a more effective gene therapy strategy.

Objective To investigate the acoustic characteristics of snoring sound in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and with simple snoring. Methods 22 patients with OSAHS and 15 with simple snoring were included in this study. Natural overnight snoring was digitally recorded and portable sleep mo-nitoring was performed simultaneously. 10 snores, which were the 1st snores after 10 cycles of obstructive apnea, from each patient in OSAHS group, and 10 snores from each patient in simple snoring group were analyzed in the time and frequency domains. Results The sound waves of snoring in the two groups exhibited different patterns both in the time and frequency domains. The snoring spectrum of patients with simple snoring showed distinct fun-damental- harmonic structures which were not clear in patients with OSAHS. The central frequency of the patients with OSAHS was higher, and 800 Hz power ratio was lower than those of the patients with simple snoring. In the OSAHS group, the central frequency of the patients with moderate-to-severe OSAHS was higher, and 800 Hz power ratio was lower than those of the patients with mild OSAHS. The differences of the two parameters were of statistical significance. Conclusion The snoring sounds in patients with OSAHS and with simple snoring have dif-ferent characteristics in time and frequency domains, indicating that it is feasible to research the OSAHS by way of snore monitoring and analyzing technique.
