Objective To discuss the treatment efficacy of washing pulmonary alveoli with the bronchoscopy in treatment of stroke with severe pneumonia in elderly patients. Methods 168 patients were collected in the study, they were divided into treatment group with bronchoscopy (110 cases) and treatment group with conventional method (58cases) . patients in the treatment group with bronchoscopy were given conventional therapy and suctioning sputum with suction tube, at the same time, the suctioning sputum and diluted with the appropriate antibiotic-sensitive local bronchoalveolar lavage were applied 1-2 times per week. Results PaO2 was higher after bronchoscopic therapy. In addition,PaCO2 ( <0.05), respiratory rate (RR) and heart rate (HR) was lower after treatment (<0.05) . Compared with treatment group with conventional method,PaO2 was improved,the RR and HR was lower in the treatment group with bronchoscopy ( <0.05) . Furthermore, the absorptive time of inflammation by Chest film and the death rate was reduced ( <0.05) . Conclusion For elderly patients with stroke with severe pneumonia,washing pulmonary alveoli with the bronchoscopy may possess positive roles to control lung infection and to improve respiratory function in the basis of conventional therapy and suctioning sputum with suction tube.

Cancer is considered as one of the major diseases endangering human health in the world, it is urgent to find a safer and more efficient treatment for cancer therapy. Gene therapy with ribonucleic acid (RNA) drugs could regulate the expression of tumor related genes, and exhibit good anti-tumor therapeutic potential in preclinical and clinical trials. Based on the differences between tumor tissues and normal tissues in microenvironment signal characteristics such as pH, specific enzyme concentration or redox gradient, various microenvironment responsive nanocarriers had been studied and developed to deliver RNA drugs to tumor tissues and cells, improving the anti-tumor efficacy of RNA drugs and reducing toxic and side effects. This paper reviews the pathophysiological characteristics of tumor microenvironment and various strategies of tumor microenvironment responsive nanocarriers, in order to provide reference for the design of safe and efficient RNA drug delivery system for cancer therapy.

Objective To detect the sperm apoptosis rate and level of reactive oxygen species (ROS) in seminal plasma and explore their correlation among infertile males. Methods Ninety-two inferitile males were divided into varicocele (VC) group (n=32), leukocytospermia group(n=30) and the other cause group (n=30), and another 24 in vitro fertilization sperm samples were sereved as controls. The routine sperm parameters including seminal pH, sperm viability and sperm density were examined by computer assisted sperm analysis, the sperm apoptosis rate was asseseed using Annexin V/PI staining, and the ROS level in seminal plasma was detected by TBA method. The differences in seminal parameters between three infertile groups and control group were compared, and the correlation of sperm apoptosis rate with level of ROS in seminal plasma was explored in each group. Results The sperm viability of three infertile groups was significantly lower than that of control group (P<0.01). The sperm apoptosis rates and levels of ROS in seminal plasma in VC group and leukocytospermia group were significantly higher than those in control group (P < 0.05 or P < 0.01). The sperm apoptosis rate was positively correlated with the level of ROS in seminal plasma in leukocytospermia group(r=0. 573, P < 0.05). Conclusion The increased sperm apoptosis rate and level of seminal plasma ROS may be related to the infertility of patients with VC and leukocytospermia. The increased level of seminal plasma ROS may be one of the causes of increased sperm apoptosis rate in patients with leukocytospermia.

Objective To compare the effect of thoracoscopic and laparoscopic surgery with conventional thoracic surgery on esophageal cancer and its influence on pulmonary function. Methods Ninety?four patients with esophageal cancer treated in the Second Affiliated Hospital of Chengdu Medical College from March 2010 to March 2016 were selected and were divided into the control group ( 54 cases) and the study group ( 40 cases) according to operation methods. The control group received traditional thoracotomy. The study group received thoracoscopic and laparoscopic surgery. The operation and pulmonary function indexes were compared. Results The operation time of the patients in the study group was significantly longer than that in the control group ( (218. 1±35. 8) min vs. (192. 3±40. 1) min,t=3. 23,P<0. 05). Intraoperative blood loss of the patients in the study group was significantly less than that in the control group ( (286. 4±83. 5) ml vs. (343. 7 ±96. 7) ml,t=3. 01,P<0. 05) . The number of lymph nodes cleared of the patients was significantly higher in the study group ( (18.0±5.4) node vs. (15.5±4.6) node,t=2.42,P<0.05).Thoracic drainage of the patients in the study group was significantly less than that in the control group ( (650. 3±61. 3) ml vs. (1153. 5 ±133. 7) ml,t=22. 12,P<0. 05). Chest tube pull out time in the study group was significantly earlier than that in the control group ( (5. 1±1. 3) d vs. (8. 0±1. 8) d,t=8. 65,P<0. 05). First exhaust time in the study group was significantly earlier than that in the control group ( (33. 2±6. 7) h vs. (40. 7±7. 3) h,t=5. 10,P<0. 05). Hospital stay in the study group was significantly shorter than that in the control group ( ( 13. 8 ± 2. 8 ) d vs. (18. 2± 3. 6) d, t=6. 42, P<0. 05) . Postoperative complications occurred in 4 cases in the study group, accounting for 10%, significantly lower than that in the control group, 15 cases, 27. 8%, the difference was statistically significant (χ2=4. 50,P<0. 05) . VC,FEV1 and MVV in the study group were significantly higher than those in the control group ( VC:( 81. 5 ± 15. 6 )% vs. ( 42. 3 ± 8. 1 )%;FEV1: ( 85. 7 ± 9. 1 )% vs. ( 43. 6 ±6. 8)%;MVV:(76. 0±8. 9)% vs. (48. 3±7. 6)%,t=15. 83,25. 68,16. 24,P<0. 05). 3?year survival rate of the study group and the control group were 45. 0% (18/40) and 44. 4% (24/54),respectively. There was no significant difference between the two groups (χ2 = 0. 01, P> 0. 05 ) . Conclusion Thoracoscopic and laparoscopic surgery for esophageal cancer has the advantages of small trauma,rapid recovery and low incidence of complications and obvious protective effect on pulmonary function. It is safe and feasible.

Objective:To evaluate the antimicrobial effectiveness of Zhenzhu Mingmu eye drops according to the requirements de-scribed in Chinese pharmacopoeia (2010 edition). Methods:Totally 7 batches of Zhenzhu Mingmu eye drops from 7 enterprises were evaluated. All the samples were tested according to the requirements described in Chinese pharmacopoeia, and the testing points of 6h and 24h were added. Results:As for bacteria, the reduction value of staphylococcus aureus in 7 days treated with Zhenzhu Mingmu eye drops from enterprise e was 0. 61g, and that in 14 days was 1. 01g. That in 7 days treated with the eye drops from the other enter-prises was all above 1. 01g, that in 14 days was above 3. 01g, and that in 14-28 days kept stable. As for fungi, the number was stable from the beginning with the treatment of the eye drops from the seven enterprises. Conclusion:Although the type and content of bacte-riostatic agent in domastic Zhenzhu Mingmu eye drops are the same, there is difference in the antimicrobial effectiveness of the product from different enterprise. The eye drops from one enterprise can't meet the requirements for type I product described in Chinese pharma-copoeia,and the others meet the requirements.
