Objective　To explore the relationship of pathological types of lung cancer with sex, age, site, and clinical diagnosis. Methods　The data of 1 310 patients with lung cancer diagnosed with fibrobronchoscopy, was retrospectively analyzed. Results　①The preliminary clinical diagnosed lung cancers which were comfirmed by fibrobronchoscopic biopsy later were mainly small cell lung cancer. ②The percentage of squamous carcinoma was significantly greater in male (78.0%) than in female (49.7%), but the percentage of adenocarcinoma was significantly higher in female (38.1%) than in male (13.1%)(P<0.0001). ③Among the patients with lung cancer, 53.7% was from 40 to 59 years old and 40.2% over 60. The average age of male patients (56.9 years old) was significantly greater than that of female (51.1 years old) (P<0.0001). ④ The average age of patients with squamous carcinoma and adenocarcinoma was greater in male than in female, but that with small cell carcinoma and squamous carcinoma was greater in female than in male. ⑤The percentage of male with lung cancer in the left lung (37.3%) was greater than that of female (26.0%), but the female had lung cancer in the right lung (59.7%) while male had (49.3%). The left and right upper lobe was more (45.4%) in male, but the right upper and lower lobe was more(43.3%) in female. Conclusion　①The fibrobronchoscopic examination is very important in the diagnosis of lung cancer. ②The pathological types and sites of lung cancer is different in different sex and age, which provide the exact bases for medical and surgical treatment for lung cancer.

Objective To explore application of pulse indicator continuous cardiac output(PICCO)in the treatment of septic shock during continuous renal replacement therapy (CRRT).Methods 34 patients with septic shock who underwent CRRT were randomly divided into the control group and the experimental group.Heart rate(HR),mean arterial pressure(MAP)and central venous pressure (CVP) were monitored in the control group.The experimental group were monitored by PICCO technology in addition to conventional monitoring,the hemodynamics parameters were collected such as end-diastolic volume index (GEDI),extravascular lung water index(EVLWI),and systemic vascular resistance index(SVRI),etc.Dehydration volume and supplementary volume were controlled by means of two group's hemodynamics parameters.The change of Acute Physiology And Chronic Health Evaluation-Ⅱ (APACHE Ⅱ),lactate (Lac),saturation of central venous oxygen(SevO2) and oxygenation index (PaO2/FiO2) were observed.Results After treatment of 72h,the decrease of APACHE Ⅱ and lactate in the experimental group was higher than those in the control group,the increase of ScvO2 in the experimental group was higher than those in the control group,the increase of PaO2/FiO2 in the experimental group was evidently higher than those in the control group.Conclusions During PICCO monitoring technique to guide CRRT therapy in patients with septic shock,the volume status of patients can be accurately controlled,organizational cycle can be improved,oxygenation of lung can be obviously improved,which contributes to treatment of septic shock.

OBJECTIVETo analyze the status of maternal health behaviors and it's risk factors for Yi-nationality women in poor rural areas of Sichuan province.

METHODSIn 2012, multi-stage stratified cluster sampling method was used to select 14 villages of two poor counties in Liangshan Yi-nationality autonomous prefecture Sichuan province. At least 10 women who have infants aged 0-12 months were selected in each simple villages, a total of 284. The structured questionnaire was developed on the basis of the theory of reasoned action. Yi-nationality female college students were trained as investigators. Research indicators included prenatal care rate, hospital delivery rate, postpartum examination rate, socio-demographic characteristics, maternal health care knowledge. χ² test was used to compare the differences of above indicators among different groups. The structural equation model were used to statistical analyze.

RESULTSIn the 284 subject women, 51.7% (147/284) women owned more than 2 children, 41.6% (118/284) women were more than 30 years old, 87.3% (248/284) women were illiteracy. The prenatal care rate was 69.7% (197/284), the hospital delivery rate was 26.8% (76/284), and the postnatal check rate was 22.9% (65/284). The influence factors of maternal health behaviors included the number of children, age and education (χ² were 10.92, 13.24, 9.58; P values were 0.027, 0.004, 0.008, respectively).The structural equation model analysis results showed that the maternal health behaviors were directly or indirectly affected by subjective norms (β = 0.236, P < 0.001), women's cognition (β = 0.226, P = 0.020) and women's attitudes on maternal health behavior (β = 0.157, P = 0.001). Among subjective norms, women have high compliance to their husbands (β = 0.850, P < 0.001), their peers (β = 0.708, P < 0.001), and their mothers-in-law (β = 0.636, P < 0.001).

CONCLUSIONThere were still serious problems in maternal health behaviors for Yi-nationality women in poor rural areas. The main factors included not only the women's cognition and attitudes for maternal health, but also the attitudes of important social relationships.

Objective:To investigate the effect of ubiquitin binding enzyme 2T (UBE2T) on the radiosensitivity of lung adenocarcinoma and unravel its possible mechanism.Methods:A total of 45 patients pathologically diagnosed with different stages of lung adenocarcinoma and treated with radiotherapy in the Second Affiliated Hospital of Zunyi Medical University from March, 2019 to December, 2021 were enrolled, and the efficacy was evaluated according to response evaluation criteria in solid tumors (RECIST1.1). All patients were divided into radiosensitive group ( n=25) and radioresistant group ( n=20). Radiosensitive group was complete remission (CR)+partial remission (PR), and radioresistant group was stable disease (SD) + progression disease (PD). Immunohistochemistry (IHC) was used to calculate the score based on the staining intensity and the number of positive cells. Chi-square test was combined to analyze the correlation between the expression level of UBE2T in paraffin specimens of lung adenocarcinoma patients and the radiosensitivity of patients. Lentivirus UBE2T-interfered (UBE2Tsh) A549 and UBE2T-overexpressed SPC-A-1 lung adenocarcinoma cells and their respective controls were constructed for irradiation and colony formation assay. The survivor fraction curve was fitted by single-hit multi-target model. The DNA double-strand break (DSB) marker γH2AX foci were detected by immunofluorescence (IF). The expression levels of UBE2T, γH 2AX and Rad51 proteins were detected by Western blot. Cell cycle and apoptosis rate of A549 were determined by flow cytometry. Binary variables were statistically analyzed by Fisher's exact probability method and measurement data were assessed by t-test. Results:High-expression level of UBE2T was correlated with the radiosensitivity of lung adenocarcinoma patients ( P<0.05). UBE2Tsh improved the radiosensitivity of A549 lung adenocarcinoma cells, and the sensitizing enhancement ratio (SER) was 1.795. UBE2T overexpression decreased the radiosensitivity of SPC-A-1 lung adenocarcinoma cells with an SER of 0.293. γH2AX foci number per cell were significantly increased in UBE2Tsh A549 cells after irradiation ( P<0.01) . Compared with the control group, the expression level of γH2AX protein was up-regulated ( P<0.01)and that of Rad51 protein was down-regulated in UBE2Tsh A549 cells after radiation ( P<0.001). Compared with the control group, the expression level of γH2AX protein was down-regulated ( P<0.05) and that of Rad51 protein was up-regulated in UBE2T overexpressed SPC-A-1 cells ( P<0.001). The proportion of UBE2Tsh A549 cells in G 2 phase was decreased ( P<0.01) and cell apoptosis was increased ( P<0.001). Conclusions:UBE2T might promote the radioresistance of lung adenocarcinoma cells by enhancing DNA DSB repair induced by radiotherapy, inducing cell cycle G 2 phase arrest, and reducing cell apoptosis.
