Objective:To investigate the prognostic value of absolute lymphocyte count (ALC) and neutrophil-lymphocyte ratio (NLR), macrophage-lymphocyte ratio (MLR) and platelet-lymphocyte ratio (PLR) before treatment in patients with locally advanced cervical cancer (LACC).Methods:A total of 175 patients newly-diagnosed with LACC admitted to Cancer Hospital affiliated to Xinjiang Medical University from August 2016 to October 2019 were enrolled in this study. Complete clinical data and ALC before treatment were recorded and NLR, MLR and PLR were calculated. Multivariate Cox′s proportional hazard regression model was used to analyze the prognostic factors of patients with LACC.Results:The progress-free survival (PFS) of LACC patients in the NLR reduction group (<3.34) and MLR reduction group (<0.315) were significantly higher than those in the NLR and MLR elevation groups (both P<0.05). The overall survival (OS) of LACC patients in the ALC elevation group (≥1.375 × 10 9/L) and the PLR reduction group (<160.575) were significantly higher compared with those in the ALC reduction group and PLR elevation group (both P<0.05). Univariate analysis showed that EQD 2Gy, the equivalent dose of HR-CTV, was an important prognostic factor of PFS in patients with LACC ( P=0.030). Multivariate Cox′s regression analysis demonstrated that FIGO staging ( HR=2.339, 95% CI 1.22-4.48, P=0.010) and concurrent chemoradiotherapy ( HR=0.213, 95% CI 0.11-0.43, P<0.001) were the independent predicators of PFS in patients with LACC. However, concurrent chemoradiotherapy ( HR=0.229, 95% CI 0.07-0.81, P=0.023) and MLR ( HR=4.933, 95% CI 1.39-17.54, P=0.014) before treatment were the independent predictors of OS in patients with LACC. Conclusions:Patients with locally advanced cervical cancer can benefit from concurrent chemoradiotherapy. HR-CTV EQD 2Gy is a critical prognostic factor of PFS in patients with LACC. The increase of MLR before treatment is an independent prognostic factor of OS in LACC patients.

Objective To observe the preliminary clinical results and safety of 27-gauge microincision vitrectomy surgery for partial vitreoretinal diseases.Methods A total of 13 patients (13 eyes) who underwent 27-gauge microincision vitrectomy surgery were enrolled.The follow-up period was 6 to 12 months.Preoperative and postoperative visual acuity and intraocular,total operative time,cutting time for removing vitreous,wound healing status,intraoperative and postoperative complications were observed.Results Mean best corrected visual acuity improved from preoperative (1.26±0.66) logMAR (0.10±0.09) to postoperative (0.63±0.52) logMAR (0.35±0.24),and the difference was statistically significant (t=2.743,P=0.018).The difference of mean preoperative intraocular pressure (IOP),IOP of postoperative day 1,day 5,one month and final postoperative visit were not statistically significant (F=0.593,P＞0.05).The mean total operative and cutting times were (36.38±14.97) min and (10.12±3.54) min respectively.Postoperative scleral incision showed linear closure,no cases of postoperative sclerotomyrelated complications such as wound dehiscence,vitreous incarceration and subcoujunctival fluid were observed.No intraoperative and postoperative complications of iatrogenic retinal breaks,endophthalmitis,choroidal detachment,retinal detachment and vitrous hemorrhage were observed.Conclusions The 27-gauge microincision vitrectomy surgery can improve postoperative visual acuity for treatment of vitreoretinal diseases and induce fewer sclerotomyrelated complications,which maybe a safer surgical approach.

OBJECTIVEThis study aims to detect the expression level of interleukin-23 (IL-23) in tongue squamous cell carcinoma tissues and its relationship with clinical prognosis, as well as explore the anti-apoptotic and drug resistance of the tongue squamous cell line-SCC9 before and after treatment with IL-23.

METHODSThe expression of IL-23 in tumor tissues from 28 tongue cancer patients was analyzed by immunohistochemistry assay. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the mRNA expression of Wingless-related integration site (Wnt)1 and c-myc in SCC9 cells treated with different IL-23 concentrations. After interferencing the β-catenin with small interfering RNA (siRNA), the expression of β-catenin, B-cell lymphoma-2 (Bcl-2), ATP-binding cassette sub-family G member 2 (ABCG2), and permeability-glycoprotein (P-gp) in SCC9 was measured by Western blot analysis. The effect of IL-23 on the apoptotic resistance of SCC9 to cisplatin was examined by methyl thiazolyl tetrazolium test.

RESULTSThe expression of IL-23 in tongue cancer tissues was correlated with lymphatic metastasis, nerve invasion, and the recurrence after therapy (P<0.05). After dealing with IL-23, SCC9 showed the upregulation effect of Bcl-2, ABCG2 and P-gp expressions. IL-23 was closely related to the activation level of the Wnt pathway and significantly strengthened the resistance to cisplatin (P<0.01).

CONCLUSIONIL-23 activates the Wnt pathway in tongue squamous cell carcinoma, thereby enhancing its resistance to apoptosis and drug.

Objective To investigate the curative effect of bronchoalveolar lavage with fiberoptic bronchoscopy combined with vibration sputum drainage in the treatment of severe pneumonia patients undergoing mechanical ventilation (MV).Methods A prospective randomized controlled trial was conducted. 286 severe pneumonia patients undergoing MV admitted to intensive care unit (ICU) of Hunan People's Hospital from January 2014 to July 2016 were enrolled, and they were divided into control group and observation group according to random number table, with 143 patients in each group. Patients in both groups received sensitive antibiotics for anti-infection, etiological treatment, and calefacient and humidifying treatment. The patients in the control group received bronchoalveolar lavage with fiberoptic bronchoscopy, and those in the observation group received bronchoalveolar lavage combined with vibration sputum drainage. The parameters of respiratory function and inflammation before and after treatment, curative effect, and prognosis were compared between the two groups.Results ① There were no significant differences in respiratory function parameters between the two groups before treatment, 2 hours after treatment, the parameters were improved in both groups. Moreover, oxygenation index (PaO2/FiO2) in observation group was significantly higher than that of control group [mmHg (1 mmHg = 0.133 kPa): 379.1±20.2 vs. 351.8±24.7], and arterial partial pressure of carbon dioxide (PaCO2) and airway resistance (Raw) were significantly lower than those of the control group[PaCO2 (mmHg): 36.5±5.8 vs. 45.3±6.9, Raw (cmH2O, 1 cmH2O = 0.098 kPa): 12.9±0.6 vs. 13.1±0.8, allP < 0.01]. ② There were no significant differences in inflammation parameters between the two groups before treatment, 24 hours after intervention, which were significantly decreased in both groups. Moreover, white blood cell count (WBC), procalcitonin (PCT) and C-reactive protein (CRP) in the observation group were significantly lower than those of the control group [WBC (×109/L): 8.2±1.7 vs. 12.8±3.7, PCT (μg/L): 15.4±2.4 vs. 21.8±3.1, CRP (mg/L): 37.1±6.1 vs. 67.2±7.2, allP < 0.01]. ③ Compared with the control group, the treatment efficiency of observation group was improved [95.1% (136/143) vs. 87.4% (125/143)], the quantity of sputum excretion was increased (mL: 49.2±12.5 vs. 36.9±11.0), duration of MV and length of ICU stay were significantly shortened (days: 6.4±3.6 vs. 9.4±2.1, 8.6±5.7 vs. 12.4±4.6, bothP < 0.01), however, there was no significantly statistical difference in 28-day mortality between control group and observation group [2.8% (4/143) vs. 2.1% (3/143),P > 0.05].Conclusion Compared with bronchoalveolar lavage with fiberoptic bronchoscopy alone, the treatment of bronchoalveolar lavage combined with vibration sputum drainage is more effective in sputum excretion for severe pneumonia patients undergoing MV, which could improve the respiratory function, reduce infection, shorten the duration of MV and the length of ICU stay, and improve the recovery.

Objective To analyze the expression characteristics of excision repair cross-complementing 1 (ERCC1), topoisomeraseⅡ (TOPOⅡ), ribonucleotide reductase M1 (RRM1), β3-tubulin and thymidylate synthase (TS) in lung cancer and their associations with the pathological types. Methods The immunohistochemical EnVision method was used to determine the expression of ERCC1, TOPOⅡ, RRM1,β3-tubulin and TS in 548 patients who were diagnosed as lung cancer from January 2011 to December 2014. Variance analysis was performed to analyze their expression characteristics among different pathological types and correlation. Results The expression positive rates of ERCC1, TOPOⅡ, RRM1, β3-tubulin and TS were 61.86 % (339/548), 91.06 % (499/548), 62.59 % (343/548), 73.18 % (401/548) and 70.44 % (386/548), respectively. The expression of ERCC1 was weak positive mostly (P<0.05), meanwhile the expression of TOPOⅡ was medium-strong positive mostly (P<0.05). In ERCC1 group, the positive rate of squamous cell carcinoma was higher than that of adenocarcinoma [57.39 % (167/291) vs. 42.61 % (124/291), P=0.000]. In weak positive of TOPOⅡ group, the proportion of adenocarcinoma was higher than that of squamous cell carcinoma [23.58 % (100/137) vs. 8.73 % (37/137), P=0.000]. In medium-strong positive of TOPOⅡ group, the proportion of squamous cell carcinoma was higher than that of adenocarcinoma [47.41 % (201/287/) vs. 20.28%(86/287), P=0.000]. The expressions of ERCC1, TOPOⅡ, RRM1,β3-tubulin and TS were irrelevant (r=0.4, P=0.397). Conclusions The expressions of ERCC1 and TOPOⅡ are higher in squamous cell carcinoma than those in adenocarcinoma. The expression of ERCC1 is weak positive mostly, meanwhile the expression of TOPOⅡis medium-strong positive mostly. There is no correlation between them.

Objective: To understand the relationships between professional identification, psychological capital and job burnout and the mediation effect of psychological capital. Methods: A total of 148 clinical nurses in 3A-level hospital in Wei fang City, Shandong hospital were recruited and assessed with general information questionnaire, professional identification scale, Psychological Capital Questionnaire (PCQ), and Maslach Burnout Inventory General Survey (MBI-GS). Results: In the job burnout, differences in age, department, education level, marital status and length of employment reached a statistically significant level (F=3.82-10.80, all P<0.05). Job burnout was significantly negatively related to professional identification and psychological capital, respectively (r=-0.37, -0.34, all P<0.01). Professional identification positively predicted psychological capital (β=0.73, P<0.01), whereas psychological capital negatively predicted job burnout (β=-0.55, P<0.01); psychological capital played a mediating role between professional identification and job burnout. Conclusions Professional identification and psychological capital are significant predicting factors of job burnout. Psychological capital fully mediates the relationship between professional identification and job burnout.
