Objective To compare the efficacy of continuous positive airway pressure (CPAP) with that of surgical treatment for obstructive sleep apnea-hypopnea syndrome (OSAHS) in elderly patients. Methods Seventy patients with OSAHS were divided into a study group and a control group according to different treatment methods. The study group received CPAP, while the control group underwent surgical treatment. One month after treatment, apnea-hypopnea index (AHI), lowest oxygen saturation (LSaO2), ESS scale value, coagulation factors, and platelet count were measured in both groups. Results AHI and LSaO2 were lower and ESS scale value was higher in the study group than in the control group, but with no significant differences (P>0.05). After treatment, all the indexes of coagulation factors were increased in the control group, but only plasma clotting factorⅡactivity had a significant statistical difference (P<0.05); (FⅡ: C) and (FⅧ: C) were significantly lower in the study group than in the control group (P<0.05); platelet count significantly increased in the control group (P<0.05), but markedly declined in the study group (P<0.05). Conclusions Both CPAP and surgical treatment have a better effiacy for obstructive sleep apnea-hypopnea syndrome. CPAP can more effectively improve coagulation function and lower the risks of complications.

Pancreatic cancer is a common disease with a poor prognosis. Despite recent advance in the field of diagnos-tic technique, surgical resection and adjuvant therapy for pan-creatic cancer, the overall 5-year survival rate is still less than 5%. This is due to its aggressive growth behavior, early local invasion and metastasis, and resistance to chemotherapy and radiation therapy. Surgical treatment is still regard as the only chance for curing pancreatic cancer. Many new strategies in the surgical treatment of pancreatic cancer, including extended lymphadeneetomy, vascular resection, the use of laparoscopy, surgery for metastastic or recurrent disease, and neoadjuvant therapy, are currently under debate. In this review, we discuss the current status of surgical treatment for pancreatic cancer, and highlight the controversies and focus.

Objective To observe clinical effect of treating helicobacter pylori infection with self-designed gastritis granule. Methods 37 patients of Helicobacter Pylori (Hp) infection with chronic gastritis accompanied by gastric mucosa atrophy and erosion were randomly recurited into a control group and a treatment group. The control group was treated with PPI trigeminy therapy, and the treatment group was treated with self-designed gastritis granule combined with PPI trigeminy therapy. Both groups were treated for continuous four weeks. Results The eradication rate of Hp in treatment group was significantly higher than that of the control group (P<0.05) .Conclusion The treatment of self-designed gastritis granule on chronic gastritis accompanied by gastric mucosa atrophy and erosion has effective results.

BACKGROUND: Acinetobacter baumannii (AB) bacteremia is an increasingly common and often fatal nosocomial infection. Identification of morbidity and mortality risk factors for AB bacteremia in emergency department (ED) patients may provide ways to improve the clinical outcomes of these patients. METHODS: The records for 51 patients with AB bacteremia and 51 patients without AB infection were collected and matched in a retrospective case-control study between 2013 and 2015 in a singlecenter ED. Risk factors were analyzed by Chi-square and multivariate logistic regression statistical models. RESULTS: A signifi cant risk factor for morbidity was the presence of a central venous catheter (CVC) (P<0.001). The mortality rate for the 51 patients with AB bacteremia was 68.6%. Risk factors for mortality were the presence of a CVC (P=0.021) and an ED stay longer than two weeks (P=0.015). CONCLUSION: AB infections lead to high morbidity and mortality. The presence of a CVC was associated with higher morbidity and mortality in patients with AB bacteremia. Avoiding CVC insertions may improve outcomes in ED patients with AB bacteremia.

Objective To study a new method for extracting agarose. Methods In 1.5% agar solution, adding the cation resin exchanged by NH~+_ 4 to take off metal ions, then using the OH~ - basic resin to absorb agaropectin. Results and Conclusion The extracting rate was 57%, gel strength reached 560 g/ cm~ 2 , the agarose has good electricity function by measuring the gentian violet electrophoresis and the DNA gel electrophoresis, so it is suitable for bioche- mistry and molecular biology electrophoresis. It is a kind of simple and low cost method for extracting agarose which better than the EDTA- 2Na method and DEAE cellulose method.

Objective: To investigate the effect of neoadjuvant chemotherapy (NACT) on microvessel density (MVD)/ lymphatic microvessel density (LMVD) in locally advanced uterine cervical cancer and its clinical impact. Methods: Seventy patients with IB2-IIB cervical cancer were recruited, and the surgical specimens of cervical cancer tissues were collected. The MVD and LMVD of cervical cancer were examined by immunohistochemistry, and the relationship between clinical response of NACT and the clinicopathological characteristics was analyzed. Results: The levels of MVD and LMVD in cervical cancer tissues were significantly higher than those in the normal cervical tissues (P<0.001; P=0.028). The MVD was related to the depth of cancer invasion (P=0.039), and the LMVD was related to the level of serum squamous cell carcinoma antigen (SCCAg) and the lymph node metastasis (P=0.017; P=0.049). The level of MVD was significantly decreased after NACT as compared with that before NACT (P=0.019). As compared with the levels of MVD and LMVD before NACT, these levels were both decreased after NACT (P=0.019; P=0.176). The overall response rate of NACT was 70.0% (49/70), and the complete response rate was 21.4% (15/70). Multivariate analysis displayed that the depth of cancer invasion was an independent factor related to the response of NACT (P=0.018, odds ratio = 0.169). Conclusion: NACT can be helpful to reduce the level of MVD and the volume of tumor in locally advanced cervical cancer. Copyright© 2011 by TUMOR.

· The mechanisms of regeneration and protection of optic nerve the represent of central nerves are researched more and more profoundly and extensively in recent years. The retinal ganglion cells protection after injury is stopping or preventing it from apoptosis mainly. The methods include glutamic acid inhibitor, nitric oxide (NO) inhibitor, neurotrophic factor, gene therapy, acupuncture, traditional Chinese medicine and so on. However, there have no any medicines or operations that play definite curative role in the retinal ganglion cells protection after injury up to now. So the ganglion cells protection is at its exploratory research stage,which will shoulder heavy responsibilities.

Objective Explore the diagnostic effect of high-sensitivity C-reactive protein (hs-CRP) in pediatric infectious diseases. Methods The BNProSpec automatic protein analyzer was used to detect the serum hs-CRP levels of children including 246 cases of bacterial infection, 132 cases of virus infection and 72 cases of healthy children (control group) . Results The serum hs-CRP levels were 57.2±19.5 mg/L,4.6±3.2 mg/L and 1.7 ±0.4mg/L in children of the bacterial infection, virus infection and normal control group, respectively. Conclusion The serum levels of hs-CRP in children with bacterial infection were significantly higher than those in other two groups,and the difference was significant ( <0.05) . The results suggested that serum hs-CRP testing has great application value in the diagnosis of pediatric infectious diseases, treatment and prognosis.

Objective To investigate the expression of NKG2D in peripheral blood of patients with cervical cancer,CIN,hysteromyoma and health person,and the expression of the human MHC class I chain-related gene A(MICA)on the correspondent tumor tissues.To discuss the anti-cervical cancer mechanism of NKG2D-MICA and immune escaping of cancer.Methods Flow cytometry analysis was used to detect the expression of NKG2D in the peripheral blood of patients with cervical cancer,CIN,hysteromyoma and health person.The expressions of MICA in part of the correspondent tissues were examined by means of reverse transcription-polymerase chain relation(RT-PCR).Results The expression of NKG2D in the patients with cervical cancer,CIN,hysteromyoma and health person were(76.87?9.39)%、(81.84?7.94)%、(86.77?8.68)%、(93.968?4.9)%,respectively.Compared with the normal group,the NKG2D expression in the particular disease group was of statistical significance,however,it is not statistically significant in the comparison in the particular disease group.The rate of MICA mRNA expression in cervical cancer was significantly higher than that in hysteromyoma and health tissues,and its difference is of statistical significance.But it is not statistically significant for the normal group to compare with the other group.Conclusion The activity of NK cell and the anti-cancer cellular immunity level reduce in patients with cervical cancer.The decrease of the receptor NKG2D is a reason for the descend of the activity of NK cells.MICA mRNA expression increases in the cervical cancer,and it has the tendency of up-regulation with the progress of pathological changes.It is relative to malignant transformation from cervical squamous intraepithelial lesion to cervical cancer;the immune-escape of cervical cancer probably is relative to the down-regulation of NKG2D and the up-regulation of its ligand MICA.

ObjectiveTo observe the clinical effect of Chinese medication plus warm needling in regulating the hypothalamo-pituitary-ovarian axis (HPOA) for anovulatory infertility.MethodThe relevant clinical data of sixty-seven women with infertility were comprehensively analyzed, to summarize the risking factors for anovulatory infertility, and then the subjects were randomized into an observation group and a control groupby their visiting sequence. The control group was intervened by orally taking Bushen Tiaojing Cupailuan (tonifying kidney, regulating menstruation, and promoting ovulation) decoction, while the observation group was by warm needling in addition to taking the same decoction. The clinical efficacies, growth of endometrium, and size of follicle were compared between the two groups.ResultWarm needling plus Bushen Tiaojing Cupailuan decoction produced a positive effect in treating anovulatory infertility, andthe pregnancy rate of the observation group was significantly higher than that of the control group (P<0.05).ConclusionThe effect produced by warm needling plus Bushen Tiaojing Cupailuan decoction has a comparatively high clinical value.
