Objective: This work aimed to investigate the negative prognostic factors of bronchioloalveolar carcinoma (BAC) and adenocarcinoma with BAC characteristics, based on the 2004 pathological classification by the World Health Organization (WHO), which were further verified with the new pathological classification of lung adenocarcinoma (WHO 2011), to identify crucial factors that determine the prognosis of BAC and adenocarcinoma with BAC features, and to prove the coherence of the two pathological classi-fications in assessing clinical prognosis. Methods: Upon pathological diagnosis, some of the 193 cases of BAC or adenocarcinoma with BAC features were categorized into adenocarcinoma in situ (AIS) or minimally invasive adenocarcinoma (MIA), based on the 2011 WHO classification. Gender, age, tumor size, familial cancer history, smoking history, TNM stage, symptoms, duration of symp-toms, and the choice of treatment were recorded and analyzed for prognosis. The survival rate was calculated by Kaplan-Meier method. Log-rank test was introduced to compare the survival rate. Univariate and multivariate factors for the survival rate were analyzed by Cox proportional hazards regression model. Results:The overall 1-, 3-and 5-year survival rates were 84.3%, 60.6%, and 45.6%, respec-tively. Cox univariate analysis revealed that the tumor size, symptoms, TNM stage, pathological outcomes, and the choice of treatment were all prognostic factors. Cox multivariate analysis revealed that TNM stage was an independent prognostic factor for patients with BAC. Data from patients with AIS and MIA revealed better survival. Conclusion:The overall survival rate of BAC and adenocarcino-ma with BAC features are superior to that of other non-small cell lung cancer (NSCLC). The clinical symptoms are non-specific com-pared with other types of NSCLC. Clinical stage at diagnosis is a key prognostic factor, such that early correct diagnosis significantly improves survival. The new classification criteria of WHO, released in 2011, is more elaborate and more conducive to clinical practice.

Objective To investigate the effects of the FKBP51 · PHLPP · AKT signal module on the phosphorylation of Akt and hippocampal neuronal injury after the cerebral ischemia / reperfusion induced neuronal death in rat hippocampus.Methods Transient(15 min)brain ischemia was induced by the four-vessel occlusion in Sprague-Dawley rats.6 rats were used in each group.The antisense oligodeoxynucletides(AS ODN)of PHLPP2 (PH domain and leucine rich repeat protein phosphatases) was used to suppress the assembly of FKBP51 · PHLPP · Akt signal module by intracerebroventricular infusion once per day for 3 days before ischemia.After 6 hours reperfusion,interactions of PHLPP2 and FKBP51 (FK506 binding protein 5) with Akt were detected by immunoprecipitation (IP) and the phosphorylation of Akt was detected by western blot (IB).After 5 days reperfusion,rats were perfusion-fixed with paraformaldehyde and Hematoxylin-Eosin staining was used to examine the survival number of CA1 pyramidal cells of hippocampus.Results Compared to PHLPP2 MS ODN group(1.24±0.24,1.68±0.11,0.58±0.01),PHLPP2 AS ODN suppressed the assembly of the FKBP51 · PHLPP · Akt signaling module(1.06±0.01,1.04±0.13),and increased the phosphorylation of Akt(0.76±0.02) (P＜0.05).Furthermore,compared to PHLPP2 MS ODN group (20.1±2.5),the number of surviving neurons significantly increased in PHLPP2 AS ODN group(88.3±2.7)(P＜0.05).Conclusion The increasing assembly of FKBP51 · PHLPP · Akt signal module can damage CA1 pyramidal cells of hippocampus by inhibiting the phosphorylation level of Akt.

Objective: To observe the effect of moxa-stick moxibustion plus recombinant human granulocyte-colony stimulating factor (rhG-CSF) in preventing chemotherapy infection in gastric cancer and its effect on immune function. Methods: A total of 70 patients with gastric cancer treated by chemotherapy were randomly divided into an observation group and a control group, with 35 cases in each group. The control group was given rhG-CSF, and the observation group was given additional moxa-stick moxibustion on the basis of rhG-CSF. Both groups were treated for 2 chemotherapy cycles, totally 6 weeks. The number of patients with infection, the duration of infection and the duration of continuous use of antibiotics were observed. The leukocytes and granulocytes counts, the levels of tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured before and after treatment, and the levels of CD4, CD8 and natural killer (NK) cells were analyzed. Results: The infection rate of the observation group was significantly lower than that of the control group (P<0.05), and the duration of infection and the duration of continuous use of antibiotics were also shorter (P<0.05). After treatment, the leukocytes and granulocytes counts in the two groups were higher than those before treatment (all P<0.05). After treatment, the levels of TNF-α and IFN-γ of the patients in the two groups were improved (all P<0.05), and there were significant differences between the observation group and the control group (P<0.05). After treatment, the numbers of CD4, CD8, and NK cells in the observation group increased significantly (all P<0.05), but the changes in the control group were not significant (P>0.05). Conclusion: Moxa-stick moxibustion plus rhG-CSF can significantly reduce the incidence and severity of chemotherapy infection in gastric cancer, increase the leukocytes and granulocytes counts, and regulate the levels of inflammatory factors, which may be related to the improvement of the immune function of the patients.
