Objective To investigate the level and influencing factors of subjective well-being of nurses and establish a model of the relationship of job stress, self-efficacy and subjective well-being. Methods Totally 438 nurses from 5 hospitals in Changchun city were investigated with the self-designed demographic questionnaire, General Well-Being Scale, Nurse Job Stressors Scale and Self-Efficacy Scale. Results The total score of subjective well-being was (71.36 ± 18.83) points. Single factor analysis found that age (F=1.759, P<0.01), department (F=1.712, P<0.01), professional title (F=1.364, P<0.05), years of working (F=1.420, P<0.05) and monthly income (F=1.632, P<0.01) were statistically significant. Multiple linear regression analysis showed that sex (t=-2.447, P<0.05), the first factor of job stress (t=-5.033, P<0.01), the second factor (t=-2.478, P<0.05), the third factor (t=-2.315, P<0.05), the fifth factor (t=-5.862, P<0.01) and self-efficacy (t=10.705, P<0.01) were the predictive effectton of subjective well-being. The result of path analysis shows that self-efficacy has a significant effect of adjustment on job stress and subjective well-being (direct effects=-0.62, indirect effects=-0.24, P<0.01). Conclusions The nurse subjective well-being is in the medium level. Hospitals and all related departments should take effective measures to reduce or eliminate unfavorable factors and increase the protective factors, and then improve the level of nurses′subjective well-being and nursing quality.

Objective To explore the influence of introducing standardized patient (SP) into problem-based learning (PBL) to the autonomous learning abilities for undergraduate nursing students based on clinical thinking training. Methods To select 2 classes randomly from full-time professional nursing undergraduate classes enrolled in 2012 from Tianjin university of traditional Chinese medicine, was divided into the experimental group and the control group by random number table method. The control group uses PBL teaching mode, and the experimental group adopts introducing SP into PBL teaching mode. Course lasts for 4 weeks, a total of 18 hours. To evaluate two groups nursing students′the percentage of asking questions by themselves and examination results in the end of the course, and evaluate nursing students′autonomous learning ability before and after the course and after three months of clinical practice respectively. Results The percentage of asking questions by themselves and examination results of the experimental group were 87.80%(36/41) and (84.24±5.12) points, (87.85±5.44) points, the control group were 68.89%(31/45) and (81.51±6.63) points, (84.40±7.96) points, the difference was statistically significant (χ2=4.46, t=2.13, 2.37, P<0.05);There was no statistical significance between two groups in the score of autonomous learning ability before the course (P>0.05), while after course and after three months of clinical practice of the experimental group were (93.71±9.56) points, (103.27±11.92) points, the control group were (85.47 ± 9.28) points , (91.36 ± 10.56) points, the difference was statistically significant (t=3.56, 4.89, P<0.01). Conclusions The teaching mode of introducing SP into PBL can train and improve the autonomous learning ability of undergraduate nursing students,and can provide reference for nursing teaching mode reform.

Objective To investigate the expression of CYP2W1 in gastric cancer and its effect on proliferation and invasion.Methods CYP2W1 protein expression in 326 gastric cancertissues and in the corresponding normal gastric mucosa was measured by immunohistochemstry.The expression of CYP2W1 mRNA in 10 randomly chosen gastric cancer tissues and its corresponding normal gastric mucosa was tested by semi-quantitative RT-PCR.4 groups pairs of gastric cancer and normal gastric mucosa cell lines were constructed.CYP2W1 expression in each of the cell line was tested.The effect of CYP2W1 expression on the proliferation and invasion capacity of the gastric cancer cells was studied by MTT experiment and transwell cell experiment.Results Expression of CYP2W1 protein in the gastric cancer tissues is higher than that in normal gastric mucosa (26.7％ vs.0,x2 =100.396,P ＜ 0.05).CYP2W1 mRNA in the gastric cancer tissues is higher than that in normal gastric mucosa [(0.413 ± 0.026) vs.(0.074 ± 0.005),t =28.115,P ＜ 0.05].CYP2W1 protein expression in the gastric cancer cell lines is higher than that in normal gastric mucosa cell lines [(0.481 ± 0.024) vs.0,t =49.097,P ＜ 0.05].The growth capacity of CYP2W1 positive gastric cancer cell is stronger than that of CYP2W1 negative cells (P ＜ 0.05),and CYP2W1 positive gastric cancer cells are also more of invasiveness,[(63 ±8) vs.(18 ±3),t =24.134,P ＜0.05].Conclusions CYP2W1 is only expressed in the gastric cancer tissues,hence it is closely related to the growth multiplication,and invasiveness of gastric cancer cells.

Tertiary lymphoid structure (TLS) is the ectopic lymphoid tissue around the chronic inflammatory site of tumor, infection diseases, autoimmunity diseases, organ transplantation and so on. TLS is regarded as the vital niche of antitumor immune response in tumor microenvironment for abundant immune cells, and is correlated with better clinical outcomes and immunotherapy response in most solid tumors. As a typical inflammation-driven cancer, hepatocellular carcinoma (HCC) is controversial with the influence of TLS on patients prognosis. In this paper, the composition, formation mechanism, recognition and clinical value of TLS in HCC were briefly reviewed.

Objective To compare endoscopic stenting with surgery for pyloric obstruction caused by unresectable gastric cancer.Methods Between June 2002 and June 2012,6 patients underwent endoscopic stenting and 70 did surgery for gastric outlet obstruction caused by gastric cancer.Results There were no significant difference in technical success rate and clinical success rate between the stenting and surgery groups (P ＞ 0.05).The stenting group had shorter time to oral intake,and shorter length of hospital stay [(2.5-± 3.1) d vs.(6.6 ± 3.5) d,t =-7.0,P ＜ 0.001].The incidence of early complications was significantly higher in the surgery group.However,the rates of late complications were significantly lower in the surgery group.Moreover,the surgery group was significantly associated with a longer patency duration [(295.8 d,95％ CI:260.7-330.8) vs.(168.2 d,95％ CI:134.7-201.7 d),P ＜0.001] and overall survival [(307.6 d,95％ CI:272.4-342.8 d) vs.(229.6 d,95％ CI:195.1-264.3 d),P =0.003].Conclusions Both endoscopic stenting and surgery are effective palliative therapy for gastric outlet obstruction caused by gastric cancer.Endoscopic stenting is associated with better shortterm outcomes.Surgery is preferable to ES in longer patency duration.

Objective To investigate the effect and mechanism of Qianggu Tongbi capsule on osteoarthritis factors in rats.Methods Osteoarthritis(OA)rat model was established by anterior cruciate ligament transection method.Rats were ran-domly divided into model group,Qianggu Tongbi capsule group and glucosamine group.HE staining was used to identify the model.Toluidine blue staining was used to observe the changes of cartilage.Real-time quantitative polymerase chain reaction(qRT-PCR)was applied to detect the expression of Toll-like receptors(TLR4)and nuclear factor kappa-B(NF-κB)in each group.The levels of IL-1β,TNF-α,and IL-6 were measured by the enzyme linked immunosorbent assay(ELISA)kit.The levels of TLR4 and p-NF-κB were detected by immunohistochemistry.Results HE staining showed that,compared with the control group,a large number of inflammatory cell infiltration and synovial tissue thickening were observed in the model group,while the inflammatory cell infiltration and synovial tissue thickening were not obvious in the Qianggu Tongbi capsule and glu-cosamine groups.Toluidine blue staining results showed that chondroitin sulfate in the cartilage tissue of the model group was significantly reduced compared with the control group,while levels of chondroitin sulfate in the Qianggu Tongbi capsule group and glucosamine group were significantly increased.Compared with control group,the expression and immunohistochemical re-sults of TLR4 and NF-κB,and the levels of IL-1β,TNF-α and IL-6 in model group were significantly increased(all P＜0.05).Compared with model group,the expression and immunohistochemical results of TLR4 and NF-KB,and the levels of IL-1β,TNF-α and IL-6 in Qianggu Tongbi capsule group and glucosamine group were significantly decreased(all P＜0.05).Conclusion Qianggu Tongbi capsule can inhibit expression of TLR4 and NF-κB by reducing the production of inflammatory factors to a-chieve the effect of treatmenting osteoarthritis.

Objective To explore the clinical efficacy of secondary posterior internal fixation after transoral anterior atlantoaxial release under 3D operative microscopy for treatment of irreducible atlantoaxial dislocation.Methods From January 2014 to May 2016,12 patients with irreducible atlantoaxial dislocation were treated with secondary posterior internal fixation after transoral anterior atlantoaxial release under 3D operative microscopy in our hospital.They were 7 males and 5 females,with an average age of 37.1 years (from 25 to 54 years).The efficacy was analyzed in terms of their visual analogue scale (VAS),Japanese Orthopaedic Association (JOA) scoring,improvement rate of neurological function,American Spinal Injury Association (ASIA) grading,atlas-dens interval (ADI),space available for the cord (SAC) and cervicomedullary angle (CMA) before and one year after operation.Results The patients were followed up for more than one year.All the atlantoaxial joints obtained anatomic reduction.Their preoperative values of VAS (5.73 ± 1.36 points),JOA score (9.03 ± 2.12 points),ADI (8.34 ± 1.12 mm),SAC (9.53 ± 0.69 mm) and CMA (121.23°±4.32°) were significantly improved one year after operation (1.21 ±0.63 points,14.32±2.51 points,2.83 ± 0.36 mm,14.23 ± 1.22 mm and 153.53° ± 9.25°, respectively) (P ＜0.05).The improvement rate of neurological function increased gradually with the postoperative time,reaching 94.14％ ±5.11％ one year after operation.The postoperative ASIA grading was significantly improved too one year after operation (P ＜ 0.05).Conclusion Secondary posterior internal fixation after transoral anterior atlantoaxial release under 3D operative microscopy may lead to fine clinical efficacy one year after operation for patients with irreducible atlantoaxial dislocation.

Objective:To explore the differences in bacterial community structure between proximal colon cancer (PC), distal colon cancer (DC), and rectal cancer (RC), and the values of featured microbiota in differentiating PC with tumor markers.Methods:This case-control study enrolled 85 newly diagnosed colorectal cancer patients, including 22 PC, 15 DC and 48 RC patients, and 8 colorectal adenoma patients from May 2019 to July 2022 at the Department of General Surgery, Anyang Oncology Hospital. The blood and fecal samples were collected before surgery and then subjected to biochemical tests for tumor markers and 16S rDNA tests, respectively. SPSS (27.0.1) was applied to perform the t-test, one-way ANOVA, Mann-Whitney U test, Kruskal-Wallis H test, and Chi-Squared Test. Also, the receiver operating characteristic curve (ROC) was plotted on tumor markers and/or f_Bacteroidaceae with SPSS software .Results:All groups had significant differences in the CA125 ( F=3.543, P<0.05), CA72-4 ( F=3.596, P<0.05), and serum tumor-associated materials (TAM) levels ( F=5.787, P<0.01). In PC group, the levels of CA125 [PC vs RC, (36.84±6.30) kU/L vs (12.73±4.21) kU/L, P<0.01] and CA72-4 [PC vs RC, (45.56±10.86) kU/L vs (3.30±7.63) kU/L, P<0.01] were significantly higher than that of the RC group, while the level of TAM was remarkably elevated in PC group than in RC group [PC vs RC, (124.84±5.19) U/ml vs (102.44±3.63) U/ml, P<0.001] and CRA group [PC vs CRA, (124.84±5.19) U/ml vs (95.39±8.42) U/ml, P<0.01]. The LEfSe analysis showed that the featured microbiota in the PC group included f_Bacteroidaceae, f_Neisseriaceae, f_Clostridiaceae_1, f_Spirochaetaceae, and so on. The largest area under the ROC belonged to the combination of TAM and f_Bacteroidaceae, which reached 0.845 (95% CI 0.747-0.944), with sensitivity being 0.857 and specificity being 0.815. Conclusions:There is heterogeneity in gut microbiota composition among PC, DC, RC, and CRA. The combination of gut microbiota and tumor biomarkers demonstrated good differentiating effects in proximal colon cancers.

OBJECTIVE: To retrospectively analyze the clinical characteristics and prognostic factors of patients with primary cutaneous lymphoma. METHODS: The clinical data of 22 patients with primary cutaneous lymphoma admitted to Xinjiang Hotan District People's Hospital, Heji Hospital affiliated to Changzhi Medical College and the Fifth Medical Center of PLA General Hospital from January 2013 to June 2021 were retrospectively analyzed. RESULTS: The incidence of primary cutaneous T cell and NK/T cell lymphoma was about 91.9/100 000, and the incidence of primary cutaneous B cell lymphoma was about 14.5/100 000. The overall survival (OS) of patients aged ≥65 years was significantly shorter than that of patients younger than 65 years (P <0.05). Patients with elevated β₂-microglobulin (β₂-MG) had shorter OS and progression-free survival (PFS) (both P <0.05). Patients who achieved complete/partial response after initial treatment had longer OS than those with stable or progressive disease (P <0.05). There were significant differences in OS and PFS among patients with different pathological types of primary cutaneous lymphoma that originated from T and NK/T cells, the OS and PFS of patients with mycosis fungoides were longer than those of patients with other pathological types (both P <0.05). In addition, disease stage might also affect the PFS of the patients (P =0.056). CONCLUSION The age, disease stage, β₂-MG level, pathological type and remission state after treatment of the patients were related to the clinical prognosis.
