Objective To compare health related quality of life (HRQOL) between modified and traditional cutaneous ureterostomy, and explore the reasons for these differences, in order to provide the basis of HRQOL for the choice of cutaneous ureterostomy. Methods A total of 53 patients underwent cutaneous ureterostomy were selected, and the patients were divided into traditional cutaneous ureterostomy group (traditional group, 21 cases) and modified cutaneous ureterostomy group (modified group, 32 cases) according to the surgery method. The patients were evaluated by functional assessment of cancer therapy-bladder (FACT-BL), and the HRQOL was compared between 2 groups. Results There were no statistical differences in HRQOL score at 1, 3, 6 and 9 months after surgery between 2 groups (P>0.05). The HRQOL score at 12 months after surgery was significantly higher in modified group than that in traditional group:(141.5 ± 10.4) scores vs. (123.1 ± 5.2) scores, and there was statistical difference (P<0.01). There were no statistical differences in the scores of physiology status, society/family status, emotional state and functional assessment of cancer therapy-general (FACT-G) at 12 months after surgery between 2 group (P>0.05). But the scores of functional status and bladder cancer special scale (BSS), total score of FACT-BL in modified group were significantly higher than those in traditional group:(26.0 ± 2.5) scores vs. (23.8 ± 3.5) scores, (46.7 ± 6.2) scores vs. (34.8 ± 5.5) scores, (143.9 ± 15.7) scores vs. (117.5 ± 8.1) scores, and there were statistical differences (P<0.01). Conclusions The HRQOL at 12 months after surgery in modified cutaneous ureterostomy is better than that in traditional cutaneous ureterostomy. Therefore, if the patient's physical condition permits, priority should be given to modified cutaneous ureterostomy to reduce the complications and improve the quality of life.

Objective To observe the clinical effect on sleep improvement about acupoint application in treating the chronic insomnia of Liver-stagnation and Spleen-deficiency Syndrome.Methods A total of 68 patients with chronic insomnia with Liver-stagnation and Spleen-deficiency Syndrome were randomly and blindly divided into treatment group and control group by registration order. In the treatment process, 1 was eliminated and 33 were completed in the treatment group, 2 were eliminated and 32 were completed in the control group. The treatment group underwentAn Mian Tietherapy half an hour before bed and the control group underwent placebo therapy in the same way of treatment group. Two groups were treated for 40 days and followed-up visit six months. The change of Pittsburgh Sleep Quality (PSQI), Index Insomnia Severity Index (ISI) and TCM Syndromes Scale were detected.Results The clinical total effective rate of treatment group was 72.7% and the control group was 9.4%, and the difference was statistically significant (χ2=46.977,P<0.01). The PSQI scores after treatment (7.55 ± 1.52vs. 13.90 ± 2.44,t=148.165), and follow up 1 month (8.97 ± 2.51vs. 13.17 ± 2.79,t=37.926) in the treatment group were significantly lower than those in the control group (P<0.01). The ISI scores after treatment (7.03 ± 3.37vs. 20.89 ± 4.40,t=73.75), and follow up 1 month (9.81 ± 3.16vs. 19.41 ± 3.66,t=40.79) in the observation group were significantly lower than those in the control group (P<0.01). The TCM Syndromes Scale scores after treatment (2.05 ± 1.09vs. 6.98 ± 1.23,t=17.116), and follow up 1 month (4.06 ± 1.59vs. 6.83 ± 0.91,t=68.055) and follow up 6 month (5.12 ± 1.84vs. 7.19 ± 1.07,t=27.716) in the observation group were significantly lower than those in the control group (P<0.01).Conclusions Acupoint application could obviously change the sleep quality and Chinese medicine symptom in chronic insomnia of Liver-stagnation and Spleen-deficiency Syndrome.

According to the current situation of biochemistry teaching and the theoretical characteristics of constructivism,the necessity and feasibility of applying constructivism to the biochemistry teaching were analyzed.Consequently,the implementation strategies of constructivism theory in the process of biochemistry teaching were introduced in detail.Through the reasonable choice of teaching content and the optimal combination of various teaching methods,it was helpful not only to realize the student-centered active construction of knowledge,but also to improve the comprehensive quality of students.At last,we performed a dialectical thought on the constructivism theory.In the concrete teaching practice,the different teaching theories should be used rationally and comprehensively based on the actual situation to improve the teaching quality of biochemistry.

Objective: To observe the effects of acupoint sticking therapy of different dosages and durations on the subjective and objective sleep indicators in insomnia patients.Methods: Ninety-six patients with insomnia due to liver-Qi stagnation and spleen deficiency were divided into a high-dosage 7 d group (25 cases), a high-dosage 14 d group (22 cases), a low-dosage 7 d group (21 cases), and a low-dosage 14 d group (28 cases) using the random numbers generated in a stratified and stage-by-stage manner in combination with the visiting sequence. The four groups all received the same acupuncture treatment, but acupoint sticking therapy varied in dosage and duration. Before and after treatment, the actigraphic readings (total time in bed, total sleep time, sleep efficiency, number of wake bouts, length of wakes after asleep, and sleep latency), Pittsburgh sleep quality index (PSQI) score, and symptoms score of traditional Chinese medicine (TCM) were observed. A correlation analysis was conducted among the subjective and objective indicators. Results: The PSQI score was positively correlated with the total time in bed and total sleep time (P<0.05). After treatment, the sleep latency, PSQI scores, and TCM symptoms scores changed significantly in the four groups (P<0.05). The total sleep time and sleep efficiency gained improvements after treatment in the high-dosage 14 d and low-dosage 14 d groups (P<0.05). The high-dosage acupoint sticking groups had longer total sleep time compared with the low-dosage groups of the same treatment duration (P<0.05). After treatment, the length of wakes after asleep, PSQI scores, and TCM symptoms scores were better in the 14 d groups than in the 7 d groups of the same acupoint sticking dosage (P<0.05). Conclusion: Given the same acupuncture treatment, acupoint sticking therapy of different treatment durations produces different effects on the length of wakes after asleep, PSQI score, and TCM symptoms score in insomnia patients, and the 14-day acupoint sticking treatment is superior to the 7-day treatment.

Objective:To explore the expression of long non-coding RNA LINC00630 in bladder cancer cell lines, and to explore the effect of interference with its expression in vitro on the proliferation and migration of bladder cancer cells.Methods:Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of LINC00630 in bladder cancer cell lines 5637, BIU-87, T24, J82 and normal bladder epithelial cell line SV-HUC-1. The bladder cancer cell line with the highest LINC00630 expression was selected for follow-up experiments, then the cell line infected with the control lentivirus was used as the control group, and the cell line infected with the lentivirus that could interfere with the expression of LINC00630 was used as the experimental group. qRT-PCR was used to detect the expression of LINC00630 in the two groups of cells. MTS method and cell scratch test were used to detect the proliferation and migration abilities of cells in the two groups. qRT-PCR was used to detect the expression of neuregulin 1 (NRG1) mRNA in the two groups of cells, and Western blot was used to detect the expressions of NRG1 protein, cell proliferation-related proteins (cyclin D3 and CDK2) and cell migration-related proteins (Vimentin and N-cadherin) in the two groups of cells.Results:Compared with SV-HUC-1 cells (1.05±0.17), the expression of LINC00630 was significantly increased in all bladder cancer cell lines (all P < 0.01), and the expression was highest in J82 cells (relative expression 5.83±0.42). Compared with J82 cells of the control group, the expression of LINC00630 in J82 cells of the experimental group decreased (0.18±0.02 vs. 1.00±0.05, t=14.36, P < 0.01); from day 2 of transfection, the cell proliferation activity of the experimental group was lower than that of the control group (all P < 0.05). The cell scratch closure rate of the experimental group was lower than that of the control group [(27.4±7.1)% vs. (66.0±5.4)%, t = 4.31, P < 0.01]. Therelative expression of NRG1 mRNA in the experimental group was lower than that in the control group (0.34±0.03 vs. 1.07±0.24, t = 2.99, P < 0.05). Compared with the control group, the expressions of NRG1 protein, cell proliferation-related proteins and cell migration-related proteins in the experimental group were reduced. Conclusions:LINC00630 is up-regulated in bladder cancer cell lines, and interference with LINC00630 may inhibit the proliferation and migration of J82 cells by down-regulating the expression of NRG1 gene. LINC00630 may be a new molecular target for the treatment of bladder cancer.

Objective To assess the effectiveness of Z-axis automatic tube current modulation ( ATCM) technique with respect to dose reduction and image noise in the thyroid regional tissues during neck computed tomography angiography (CTA). Methods A total of 140 patients underwent neck CTA with 64-slice spiral CT, and were randomized into fixed-tube current group and ATCM group. Objective noise, CTDIw, DLP and mA of each group were recorded. Results The image qualities of all the patients were diagnostically acceptable, though the objective noise of neck in the ATCM group was higher than that in the group of fixed-tube current (P＜ 0.05 ). The radiation doses in the ATCM group [ CTDIw (35.99±1.31 ) mGy, DLP (11 121.39 ±5.51) mGy·cm] were significantly inferior to those in the group of fixed tube current [ CTDIw (43.22±1.42) mGy, DLP (1514.45±5.56) mGy·cm]. Conclusions Compared with fixedtube current technique, ATCM technique could significantly reduce the radiation dose in neck CT with diagnostic acceptability of the image quality.

AIM:To investigate the efficiency of 2-methoxyestradiol (2-ME) as radiosensitizing agent for the treatment of lung cancer cells. METHODS:Cell line A549 and GLC-82 originated from human non-small cell lung cancer were cultured in vitro. Study group (2-ME in different concentrations) and control group without 2-ME were set up. Cell proliferation was measured by MTT assay that lung cancer cells were treated with 2-ME for 24 h,then the cells were exposed from 0 to 8Gy radiation,and the survival fraction was determined by clone forming test. Flow cytometry was used to measure the effects of 2-ME on cell cycle distribution. RESULTS:MTT assay showed minimum effective concentration value was 0.15625×10~(-6) mol/L in GLC-82 and 1.25×10~(-6) mol/L in A549 cells. Compared to control group,exposed GLC-82 cells or A549 cells to minimum effective concentration of 2-ME for 24 h before irradiation resulted in an enhancement of radiation. The protection enhancement factor was 1.98 and 2.06 in GLC-82 and A549 cells,respectively. Flow cytometry analysis of cell cycle progression demonstrated G_2/M phase arrest in both cells in a dose dependent manner. No obvious change of CDK2 activity in both GLC-82 cells and A549 cells was observed. CONCLUSION:2-ME enhances radiosensitivity by G_2/M phase arrest in the cell cycle.

Objective To investigate the molecular genetic changes of anaplastic lymphoma kinase (ALK) gene and c-myc gene in anaplastic large cell lymphoma (ALCL). Methods The structural aberrations and changes of copy numbers in ALK and c-myc genes in 72 paraffin-embedded ALCL specimens were detected by interphase fluorescence in situ hybridization (FISH). Results Among 72 ALCL specimens, ALK protein was expressed in 42, ALK gene translocation was detected in 40 specimens in which extra copies of ALK gene were detected in 17. ALK gene translocation was not found in all 30 ALK negative specimens, but extra copies of ALK gene were detected in 14 cases. The difference of incidence rates of extra copies in ALK gene between ALK positive and ALK negative specimens was not significant (P＞0.05). c-myc gene translocation was not found in any of 72 ALCL specimens, but extra copies were detected in 24 cases.Conclusion Most (75.0%) ALCL have ALK gene aberration, in which ALK gene translocations are most common (55.6%), and the extra copies of ALK gene are relatively common genetic changes (43.1%). The ALK gene aberration is only detected in ALK positive ALCL and the gene translocations are in either ALK positive and negative ALCL. There is no or rare c-myc gene translocation in ALCL, but extra copies of c-myc gene are relatively common (33.3%).
