Objective To investigate the effect of Biyankang Tablets on quality of life and recurrence rate in patients with chronic rhinosinusitis after functional endoscopic sinus surgery (FESS). Methods A total of 78 patients with chronic rhinosinusitis treated in our hospital during October 2014 to November 2016 were selected, and they were randomly divided into the control group and the traditional Chinese medicine (TCM) group according to the order of admission, with 39 cases in each group. Both groups were treated with FESS, and the TCM group was additionally treated with Biyankang Tablets. The clinical efficacy, inflammatory factors [interleukin-4 (IL-4), interleukin-8 (IL-8)], the prognosis [visual analogue scale (VAS) score of rhinosinusitis and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)], drug safety and recurrence rates in the two groups were observed. Results After treatment, the total effective rate of treatment in TCM group was significantly higher than that in the control group (89.74% vs 71.79%) (χ2=4.044, P<0.05). After treatment, IL-4, IL-8 and VAS scores in the two groups were significantly decreased, and the scores of EORTC and QLQ-C30 were significantly increased, and the changes of scores in TCM group after treatment were more significant than those in the control group (P<0.05). After treatment, there was no significant difference in the incidence of adverse reactions between the two groups, and the recurrence rate in TCM group was significantly lower than that in the control group in 1 year after treatment (P<0.05). Conclusion TCM Biyankang Tablets is significantly effective in the treatment of patients with chronic rhinosinusitis after FESS. It can significantly inhibit the expression of inflammatory factors, effectively improve the prognosis and quality of life, and significantly reduce the recurrence rate.

OBJECTIVE:To investigate the effects of gemcitabine combined with radiotherapy and chemotherapy on angiogen-esis and cell invasion ability of cervical cancer. METHODS:Totally 37 patients undergoing radical operation selected from Chongq-ing Kaizhou District People's Hospital during Jan. 2015-Jun. 2016 were divided into observation group(n=19)and control group (n=18). Control group was given 3-D conformal radiation and chemotherapy which included Cisplatin injection 70 mg/m2,ivgtt+Fluorouracil injection 600 mg/m2,ivgtt on 1st and 21st day after radiotherapy. Observation group was additionally given Gemcitabi-ne hydrochloride for injection 800 mg/m2,ivgtt,1st and 8th day after radiotherapy. A treatment course lasted for 28 d. The radical hysterectomy and pelvic lymphadenectomy were conducted after 2 courses of treatment. Clinical efficacy,microvessel density (MVD) of tumor,vascular endothelial growth factor (VEGF),Wnt1,Wnt3a,Wnt8 and β-catenin level were observed in 2 groups. The relationship of MVD with VEGF was analyzed,and the occurrence of ADR was recorded. RESULTS:The total re-sponse rate of observation group(84.2%)was significantly higher than control group,with statistical significance(P<0.05). The levels of MVD,VEGF,Wnt1,Wnt3a,Wnt8 and β-catenin in 2 groups were significantly higher than healthy tissue;above index-es of focus tissue in observation group were significantly lower than control group,with statistical significance (P<0.05). MVD was positively correlated with VEGF. There was no statistical significance in the incidence of ADR between 2 groups (31.6% vs. 27.8%,P<0.05). CONCLUSIONS:Gemcitabine combined with radiotherapy and chemotherapy can regulate the angiogenesis of cervical cancer cell and the activity of Wnt/β-catenin signal pathway,and reduce the invasion ability of cervical cancer cell,which may be the important mechanism of anti-tumor effect with good safety.

Objective To analyze the cases of malignant tumors found in health examination in our hospital, and to determine the prevalence and characteristics of malignant tumor, and to provide evidence for the development of effective early screening program. Methods A total of 468673 subjects were included from those who had health checkup from July 2009 to December 2014 at the physical examination center. The subjects were between 4 to 96 years of age, with average age of (56.0±12.5) years. Of them, there were 278484 men, 190189 women. All cases found in the examination were confirmed with pathological testing. Prevalence comparison was done withχ2 test, statistic significance level was set at P<0.05. Results Totally 753 cases of malignant tumors were found in 6 consecutive years, with an overall prevalence rate at 160.7/100000. The prevalence rate increased yearly from 50.0/100000 for the first year, and 100.6/100000, 146.1/100000, 149.1/100000, 188.9/100000, 221.6/100000 thereafter. The difference between each 2 years was statistically significant (P<0.01). The top ten malignant tumors were liver cancer, cervical cancer, lung cancer, renal cell carcinoma, esophageal cancer, gastric cancer, colon cancer, breast cancer, leukemia and thyroid cancer. The prevalence rates of malignant tumors in the top three were liver cancer, lung cancer and kidney cancer for man and cervical cancer, lung cancer and breast cancer for women respectively. With the increase of age, the incidence of malignant tumor showed a rising trend, especially for the group of over 80 years old. But women with cervical cancer in the 50-years age group was the highest. Conclusion The number of cases of malignant tumors found in the health checkup population was rising. It is important to include early screening for malignant tumor in physical examination. We should also pay attention to the relevant departments, in order to improve the early cancer detection rate and decrease the morbidity and mortality of malignant tumors.

In gradeⅠ hyperplasia, LN expression was found in basement membrane and epithelium, but FN expression was similar to that in normal tissue. In grade Ⅱhyperplasia, more LN expression was found in epithelium, but FN expression in epithelium and matrix. In grade Ⅲ hyperplasia, LN expression increased significantly in matrix and decreased significantly in epithelium as compared with those in grade Ⅱ( P

Objective To investigate the protective mechanism of Interleukin 33 (IL-33) in preventing myocardial ischemia and reperfusion injury in rats. Methods A rat model with myocardial I/R with 32the adult male SD rats , which were randomly divided into 4 groups: SO group , I/R group , IL-33 + I/R group , SB230580 + IL-33 + I/R group. The levels of LDH, CK, TNF-α, IL-6, HMGB1, Bcl-2, total caspase-3, cleaved caspase-3 and P-P38 were detected. Results After reperfusion, IL-33 significantly decreased the levels of serum LDH and CK and the expression of TNF-α, IL-6 , cleaved caspase-3 , but significantly increased the expressions of Bcl-2, p-P38 (P < 0.05). SB230580 attenuated the protective role of IL-33 on myocardial I/R in a certain degree. Conclusions IL-33 may prevent myocardial I/R injury via inhibiting inflammation and cardiocyteapoptosis by way of P38 MAPK signaling pathway.

Objective To investigate the effect of preconditioning with sodium butyrate on myocardial I/R injury. Methods Anesthetized rats were treated with sodium butyrate (100 or 300 mg/kg, i.p.) 30 mins before ischemia, and then subjected to ischemia for 30 min followed by reperfusion for 4 h. LDH, CK, TNF-α, IL-6, HMGB1, infarct size, MDA and SOD activity were measured. The infracted size was tested by TTC assay; The expression of HMGB1 was observed by western blot. Results After 4 h reperfusion, pretreatment of sodium butyrate (300 mg/kg) could significantly reduce the infarct size and the levels of LDH and CK (P<0.05)comparing to the control group; inhibit the increase of the MDA level and the decrease of the SOD level(P<0.05), also inhibit the expression of TNF-α, IL-6 and HMGB1 (all P < 0.05) induced by I/R. Conclusion Preconditioning of sodium butyrate can attenuate myocardial I/R injury by inhibiting inflammation response.

Objective To discuss the injective method, contrast agent concentration and delay time of MSCT direct venography in lower extremity vein, in order to make optimal venographic schedule. Methods Thirty-two patients with lower extremity vein diseases underwent MSCT direct venography in using different concentration and injective rate of contrast agent, and the images were analyzed. The displaying ability of MSCT direct venography in lower extremity vein segment was compared with that of X-ray venography in 22 patients. Results Blood flow correlation constructed defect was the main factor impacting image quality of CT venography in lower extremity. The image scores between the groups of injective rate 1.5 ml/s and the group of 2.5 ml/s were statistically different (χ~2=5.495, P=0.019), whereas no difference of image score was found between the group of concentration of 25% and 15% (χ~2=3.333, P=0.068). The displaying ability of CT and X-ray venography in anterior tibial vein, posterior tibial vein, popliteal vein and femoral vein was not statistically different (χ~2=2.095, P=0.148). For iliac vein, the displaying ability of CT outstripped that of X-ray venography (χ~2=8.324, P=0.004). Conclusion With the schedule of delay time 50 s, injective rate 2.5 ml/s and concentration 45 mgI/ml (nonionic 300 mgI/ml and diluted 15%), MSCT direct venography in lower extremity can acquire satisfactory image, and its displaying ability of iliac vein is better than that of X-ray venography.
