Glaucoma is a progressive optic nerve disease, it can cause structural changes of the optic nerve, resulting in irreversible damage of visual function. Early diagnosis is the key to treat the disease at an early stage to stop or delay the progression of visual functional defects. New technologies, including optic nerve and nerve fiber layer structural tests and visual functional tests, increased the diagnosis rate of primary open angle glaucoma (POAG) at an early stage.

Small cell lung cancer ( SCLC ) is one common type of lung cancer in China. No remarkable progress has been made in systemic therapy for SCLC since the 90’ s. However, there are some advances in radiotherapy ( RT) for SCLC, which make it possible to improve treatment outcomes of SCLC. Those advances are mainly made in thoracic RT and prophylactic cranial irradiation for extensive?stage SCLC, radiation dose and technology of thoracic RT for limited?stage SCLC, and significance of prophylactic cranial irradiation for early?stage SCLC. The paper reviews the research advances in the East and West to provide some help and references for readers.

Objective:To investigate the clinical features and prognostic factors of primary ovarian lymphoma(POL). Methods:A retrospective review was performed based on the clinical records of 14 POL cases treated at Tianjin Medical University Oncology in-stitute Hospital verity from 2000-6 to 2010-5. Results:The median age of patients was 47 years at presentation(range 28~62years). Ab-dominal pain was the most common initial symptom. The majority of histological subtype was B cell lymphoma, above 50%of which is diffuse large B-cell non-Hodgkin's lymphoma. A R0 resection was carried out in 2 patients who were lost to follow-up soon after sur-gery. 11 patients were treated by CHOP, FC or CHOPE chemotherapy. Chemotherapy combined with rituximab were given to 5 pa-tients. Until now, 5 patients were alive, 6 patients died, and only one patient was lost to follow up after therapy. Conclusion:POL is an extremely rare lymphoma. The ultimate diagnosis depends on histopathologic examination. Primary ovarian non-Hodgkin lymphoma should be treated with multi-modality strategies. Treatment with doxorubicin-based chemotherapy after oophorotomy is recommended. B cell lymphoma preferred to use rituximab combination chemotherapy. Abdominal cavity chemotherapy prophylaxis and irradiation can decrease the probability for recurrence .

Leukoaraiosis (LA) is a group of clinical syndrome caused by multiple etiologies.It belongs to one of the types of cerebral small vessel diseases.Studies have shown that LA usually can lead to different degrees of cognitive impairment.In recent years,with the development of imaging techniques,the studies about correlation between maging findings and cognitive impairment in LA patients and cognitive impairment are increasing gradually and have drawn some new conclusions.And thus,the understanding of the clinical significance of LA has been further deepened.This article mainly reviews the advances in research on the correlation between imaging findings and cognitive impairment in LA patients.

Twenty four patients of chronic obstructive pulmonary disease complicated with severe respiratory failure were divided into two groups randomly: sequential ventilation group and control ventilation group (n = 12 in each group). Patients in sequential group received invasive ventilation at beginning, once the pulmonary infection control window (PICW) reached the trachea cannula was extubated immediately replaced by Bi-level positive airway pressure( BiPAP) noninvasive ventilation with oral-nasal mask; while in control ventilation group the invasive ventilation was continued using pressure support ventilation (PSV) until stopping mechanical ventilation. The total ventilation time, the invasive ventilated time,the length of stay in hospital,monitoring time and the incidence rate of ventilation associated pneumonia (VAP) were evaluated in two groups. The total ventilation time [(7. 8 ±2. 5 ) d, (12 ±2. 2) d], the invasive ventilated time [(4. 9 ±2. 2)d, and (12 ± 2. 2) d] the length of hospital stay [(8. 5 ± 2. 5 ) d, (13 ± 2. 6) d] in the sequential ventilation group were significantly shorter than those in the control ventilation group (P ＜ 0.05); the incidence rate of VAP was lower than that in the control group. The results indicates that sequential ventilation with the guidance of PICW can shorten the total ventilation time, the critical monitoring time and the length of hospital stay, it can also reduce the incidence of VAP and improve the prognosis of patients.

Objective:To investigate the relationship between antibiotics use and antimicrobial resistance of Acinetobacter bauman-nii to provide reference for rational antibiotics use. Methods:The DDDs of antibiotics in the inpatients and the drug resistance rate of A. baumannii were analyzed in our hospital from 2010 to 2014. The relationship between the antibiotics use and the antimicrobial re-sistance of A. baumannii was analyzed by SPSS 19. 0. Results:From 2010 to 2014, the total DDDs of antimicrobials in our hospital were decreased year by year in the first three years, while increased significantly in the last two years. The total DDDs of cephalospo-rins always ranked the first and the DDDs of carbapenem were increased year by year. The resistance rate of Acinetobacter baumannii a-gainst multiple antibacterials was increased in varying degrees in the past five years. In addition to levofloxacin, cefoperazone/sulbac-tam and tigecycline, the resistance rate against the other antibacterials was increased up to 50% in 2014. The resistant rate of A. bau-mannii against ciprofloxacin, gentamycin, cefepime, imipenem and tazobactam/piperacillin presented a positive correlation with the DDDs of cephalosporins and quinolones(P<0. 05). The resistance rate of A. baumannii against cefepime, imipenem tazobactam/pip-eracillin and levofloxacin was also positively correlated with the DDDs of carbapenem(P<0. 05). Conclusion: Antibiotics consump-tion is related to drug resistance of A. baumannii,so it is necessary to strengthen the management of clinical antibiotics use to decrease the multidrug-resistant strains.

Objective To estimate the arterial-to-end-tidal carbon dioxide tension difference (Pa-ET CO 2 )in children with cyanotic or acyanotic congenital heart diseases;evaluate whether hyper-ventilation can reduce the tension difference or not;analyze the effect of sevofleurane on Pa-ET CO 2 . Methods One hundred and twenty patients (male 60 cases,female 60 cases,aged 1 month-6 years, ASA class Ⅱ or Ⅲ)undergoing selective cardiac surgery were randomly divided into 6 groups (n =20 each)based on right-to-left or left-to-right intracardic shunts:group A1,cyanotic with sevoflurane of 0.5 MAC;group A2,cyanotic with sevoflurane of 1.0 MAC;group B1,acyanotic with sevoflurane of 0.5 MAC;group B2,acyanotic with sevoflurane of 1.0 MAC;group C1,cyanotic with no inter-vention factors;group C2,acyanotic with no intervention factors.All the children received general an-aesthesia after placing an intravenous and arterial catheter.The value of PET CO 2 ,SpO 2 ,PaCO 2 , SaO 2 ,Hct and temperature(nasopharyngeal temperature and rectal temperature)were obtained before operation,after hyperventilation(the control groups without hyperventilation)and five minutes before surture sternum.Results The values of Pa-ET CO 2 were more than the normal one in six groups before operation.The value of Pa-ET CO 2 in group B1 was less than that in group A1,that in group B2 was less than that in group A2 and that in group C2 was less than that in group C1 before operation (P <0.01).Compared with the time point before operation,the values of Pa-ET CO 2 in groups A1,A2,B1 and B2 decreased significantly after hyperventilation (P < 0.05 or P < 0.01 ).Moreover, this reduction was more significant in groups B1 and B2.Compared with the time point before operation, the values of Pa-ET CO 2 in groups B1,B2,C2 increased significantly (P <0.01)and that in groups A1, A2,C1 decreased significantly (P <0.05)at 5 minutes before surture sternum.There was no statisti-cal difference at three different time points between group A1 and A2,B1 and B2.Conclusion The value of Pa-ET CO 2 in cyanotic children increased more significantly than that in acyanotic children.Hy-perventilation can reduce the value of Pa-ET CO 2 especially in acynanotic children with pulmonary con-gestion.The concentration (from 0.5 MAC to 1.0 MAC)of sevoflurane had little effect on the value of Pa-ET CO 2 .
