Objective To investigate the clinical efficacy of open radical mastoidectomy (ORM) combined with ear cavity angioplasty and mastoid cavity obliteration in treatment of cholesteatoma otitis media (COM). Methods Eighty-two patients with COM were divided into 2 groups according to surgical approach: control group (41 patients undergoing simple ORM) and observation group (41 patients undergoing ORM combined with ear cavity angioplasty and mastoid cavity obliteration). The clinical efficacy and recurrence rate between the 2 groups were compared. Results The total effective rate, dry ear rate and eardrum healing survival rate in observation group were significantly higher than those in control group: 95.12% (39/41) vs. 78.05% (32/41), 97.56% (40/41) vs. 75.61% (31/41) and 90.24%(37/41) vs. 73.17% (30/41), and there were statistical differences (P<0.01). The dry ear time and epithelialization time in observation group were significantly shorter than those in control group:(31.23 ±5.69) d vs. (48.12 ± 8.97) d and (24.41±3.23) d vs. (36.24 ± 5.69) d, the postoperative pure tone audiometry (PTA) and air bone gap (ABG) in observation group were significantly lower than those in control group:(25.61 ± 5.67) dB vs. (35.41 ± 8.23) dB and (13.24 ± 3.98) dB vs. (19.02 ± 5.52) dB, and there were statistical differences (P<0.01). There was no statistical difference in the incidence of complications between 2 groups (P>0.05). The recurrence rate in observation group was significantly lower than that in control group:2.44%(1/41) vs. 14.63%(6/41), and there was statistical difference (P<0.05). Conclusions The application of ORM combined with ear cavity angioplasty and mastoid cavity obliteration in the treatment of COM has significant effect, with rapid postoperative dry ear and epithelialization, fewer complications and lower recurrence rate. It should be widely applied.

Molecular methods and fluoroscopic techniques suggest that rich microbial diversity exist in the marine environment, but less than 1% of these microbes can be cultured in the laboratory conditions, and that the cultivable dominant species were even less. This limitation has long been a barrier to the development of environmental microbiology and the utilization of marine resources. In the past decade, novel methods for culture and detection of these uncultured marine microbes have successfully applied to obtain several conventionally-uncultured microbes including those from extreme environments. Those progresses have inspired researchers greatly. Developments in the research of marine microbial resources are an important basis for the study of the micro-world and deserve increasing scientific attention.

Objective To investigate the relationship of the serum bilirubin level with acute ischemic stroke (AIS), and Chinese isch-emic stroke subclassification (CISS), stroke severity and short-term outcome of AIS patients. Methods 616 patients with AIS as well as 664 patients without stroke matched with gender and age were compared and analyzed with the non-conditional Logistic regression. The AIS pa-tients were divided based on the CISS, and their bilirubin levels were compared. The AIS patients were divided into high bilirubin group and normal bilirubin group, their scores of the National Institute of Health Stroke Scale (NIHSS) as admission and discharge, and neural func-tion improvement rate were compared. Results The levels of total bilirubin (TBIL), direct bilirubin (DBIL) and indirect bilirubin (IBIL) were higher in the AIS group than in the control group (P<0.01), and the TBIL was the independent risk factors of AIS (OR=1.026, 95%CI 1.012-1.041, P<0.001). There was no significant difference of the levels of TBIL, DBIL and IBIL among the patients of CISS (P>0.05). The NIHSS score was higher in the high bilirubin group than in the normal bilirubin group as admission (P<0.05), but it was not significant as discharge (P>0.05), nor the rate of neural function improvement (P>0.05). Conclusion The serum bilirubin level elevated and correlated with the severity in the AIS patients, which might be the risk of pathogenesis and AIS. The bilirubin was not various with the CISS, and might be less involved in the short-term outcome of AIS.

Objective To investigate the risk factors of recurrent ischemic stroke, and evaluate the severity and short-term outcome. Methods From March, 2014 to March, 2015, 238 patients with recurrent ischemic stroke and 378 patients with initial ischemic stroke matched with gender and age were enrolled. The clinical data of two groups were compared and the non-conditional Logistic regression model was made to analysis the risk factors of recurrent ischemic stroke. The National Institute of Health Stroke Scale (NIHSS) score as ad-mission and discharge, and the neural function improvement rate of two groups were compared. Results The incidences of leukoarailsis (χ2=8.666), hypertension (χ2=8.189), smoking (χ2=6.973) and alcohol consumption (χ2=4.722) were higher in the recurrent group than in the pri-mary group (P<0.05). Logistic regression analysis showed that leukoarailsis (OR=1.690, 95%CI:1.198~2.384, P=0.003), hypertension (OR=1.715, 95%CI:1.135~2.592, P=0.010) and smoking (OR=1.896, 95%CI:1.233~2.915, P=0.004) were the independent risk factors of recur-rent ischemic stroke. The NIHSS scores as admission and discharge were significantly higher (t=-3.645, t=-4.675, P<0.001), and the neural function improvement rate was lower (t=2.643, P<0.01) in the recurrent group than in the primary group. Conclusion Hypertension, leuko-arailsis and smoking are independent risk factors for recurrent ischemic stroke. Recurrent ischemic stroke is more serious than initial isch-emic stroke, and the short-term neural function recovers more slowly.

Objectives To observe the pre and post-operational changes of the expressions of survivin, caspase-3 and CD44V6 in patients with colorectal cancer after intra-abdominal implantation of sustained releasing fluorouracil. Meth-ods Sixty-four patients with colorectal cancer (Dukes’stage of B and C) were divided into treatment group and control group, 32 patients in each group. The standard radical surgery was performed in two groups of patients. The fluorouracil im-plants were implanted intra-abdominally in treatment group. The peripheral blood levels of surviving and caspase-3 were de-tected by RT-PCR. The level of CD44V6 was detected by flow cytometry in two groups of patients. Results There were no significant differences in levels of survivin, caspase-3 and CD44V6 before surgery between two groups (P>0.05). The level of survivin (0.362 ± 0.183) was significantly lower at 14 days after operation in treatment group than that of control group (0.585±0.207), but the level of caspase-3 (2.001±0.146) was significantly higher than that of control group (1.654±0.111). The levels of CD44V6 were significantly lower in treatment group (1.857±0.535) and control group (3.471±0.496) after opera-tion than those before operation (9.557±1.170 and 9.729±0.943, P<0.05), and the level of CD44V6 was significantly lower in treatment group than that of control group (P<0.05). Conclusion The implant for the sustained release of fluorouracil showed a positive impact on micrometastases and prognosis of colorectal cancer, while improved the long-term efficacy of postoperative colorectal cancer.

Objective To evaluate the efficacy of aerosol inhalation ofXiyanpingversus ribavirin for the treatment of respiratory tract infections in children.MethodsPubMed, Embase, Cochrane database of Systematic Reviews, CNKI, cqvip and wanfangdata were searched. The randomized controlled trials(RCTs) of aerosol inhalation ofXiyanpingversus ribavirin injections for the treatment of respiratory tract infections in children were incuded. The quality of trials was evaluated and data analyses were performed with the Cochrane Collaboration’s software RevMan 5.0.Results A total of 7 trials were included, involving 857 patients(437 treated withXiyanping, 420 treated with ribavirin). Both of the clinical cure rate(50.11%vs. 40.71%) and clinical effective rate(91.08%vs. 75.95%) in theXiyanping group were significantly higher than those in the ribavirin group, withOR(95%CI) 1.49(1.13 to 1.97) and 3.54(1.87 to 6.71), respectively.Conclusions Aerosol inhalation ofXiyanping superior to aerosol inhalation of ribavirin for the treatment of respiratory tract infections in children. Owing to the poor quality and the small sample size of included trials, more larger good quality CRTs are required to confirm this conclusion.

This research uses six Agrobacterium rhizogenes R1601, R15384, R1000, A4, R1025 and R1 to infect silymarin explants to induce hairy roots and silibin. All of the six A. rhizogenes can induce Silybum marianum to generate hairy roots and the A. rhizogene A4 shows comparatively high infection on the plant. This research determines the condition to induce silymarin hairy roots by the factors of infection time, pre-culturing, co-culturing and pH value. The fact that MS liquid medium fits the proliferation of silymarin hairy roots is determined. Through PCR molecular identification, it can be seen that the DNA plasmids in the A. rhizogenes are successfully integrated into the genome of transformed roots. Using liquid chromatography, it is determined that the silibin content in silymarin hairy roots is 2.5 times that in the plant In this research, the silymarin hairy roots culturing system is established, which lays a foundation for the study of culturing silymarin hairy roots and producing silibin.
