The serum, aqueous humor and tear lL - 2, slL - 2, NO, TAC, and SOD of two groups were detected and compared, and the detection levels of patients with different stages were compared.
●RESULTS: The serum, aqueous humor and tear lL-2, TAC, and SOD of observation group were all lower than those of control group, the slL-2 and NO were all higher than those of control group. The serum, aqueous humor and tear detection levels of patients at different stages had obvious differences, and the aqueous humor lL - 2 were lower than those of serum and tear, the slL-2 were higher than those of serum and tear, with statistically significant differences.
●CONCLUSlON: The change of serum, aqueous humor and tear lL-2, slL-2, NO, TAC, and SOD of patients are all great, and the influence of the stages for those indexes are great too, the inflammatory response state of aqueous humor are more obvious.

OBJECTIVE:To study the classification of deviation in drug production. METHODS:From the perspective of dom-inant and hidden deviation,combining with the theory of risk management,risk of deviation was evaluated with different risk man-agement tools to define the severity of the deviation,and it was handled by different methods. RESULTS & CONCLUSIONS:Ac-cording to the identifiability of deviation in actual management,the deviation was divided into dominance and hidden deviation. The dominant deviation can be divided into deep and shallow level. Whether the causes of deviation could be cleared and the conse-quences could be estimates were judged after the shallow level classification,and the deviation was further divided into simple and complex deviation. As for deviation complex,it could be evaluated with the tools of risk management to define the deviation severi-ty. As for hidden deviation,it needed beforehand preventing with the tools of risk management directly to define deviation levels and provide reference for preventive measures. In the process of deviation management,key point is to relay on the scientific meth-od to identify and classify deviation,and divide the influence levels. Combining the theory of risk management to select and use risk tools is the effective way to solve the problem.

Objective To investigate the changes of airway resistance before and after Bronchial Diulation Test in patients with senile asthma and the effect of age on the degree of airway resistance. Methods A total of 29 (> 60 years)senile asthma patients and 21 younger(< 60 y)patients were enrolled in the study. The status of their pulmonary function was determined by MEFV(Maximum expiratory flow?volume curve)and an IOS(impulse oscillometry) system before and after Bronchial Diulation Test,The spirometric indexes such as forced vital capacity,total respiratory impedance,respiratory resistance and respiratory system reactance were collected and analyzed. Results Significant decreases of indexs were found after Bronchial Diulation Test compared with those before Bronchial Diulation Test in the study group(P<0.05,respectively). No significant difference in improvement of indexs was found between the group of patients with senile asthma(age > 60 years)and the group of healthy control(age < 60 years ). Each index of the airway resistance has a very good correlation with FEV1%,with the highest degree of relation is X5%. Conclusion The airway resistance of senile asthmatic patients was significantly improved after diuslation test and these indexes IOS would be valuable in evaluating the changes of airway resistance of senile asthma.

To compare the effect and advantage of performing rhegmatogenous retina detachment surgery under operation microscope with under direct ophthalmoscopes .METHODS: Ninety - three patients ( 93 eyes ) were randomized to two groups, Group A ( under operation microscope during rhegmatogenous retina detachment surgery, 47 cases ) , Group B ( under direct ophthalmoscopes during rhegmatogenous retina detachment surgery, 46 cases ) . All patients were followed up for 2wk to observe success rate and visual improving rate.RESULTS: Total percentage of success was 95. 74% in group A and 80. 43% in group B. The visual improving rate of group A was 82. 98% and it was 67. 39% in group B. Operative time in group A was significantly shorter than that in group B (P<0. 05). CONCLUSlON: Performing rhegmatogenous retina detachment surgery under operation microscope is ascertaining and it is more effective and handy than performing that surgery under direct ophthalmoscopes.

Objective To investigate the safe region for screw fixation in atlas lateral mass by ra- diologic measurements to conduct the operative procedure.Methods The dimensions of the pedicles were determined in 30 patients with normal atlas by CT scan and three dimensional reconstruction images of the upper cervical spine.The space available for the screw(SAS)was defined as the perpendicular distance between two lines tangential to the spinal canal and the transverse foramen,respectively.SAS was evaluated at 0?(SAS1)and 10?(SAS2)insertion angles.The location of screws in 13 cases of opera- tion were observed by CT scan images measurements of the cervical spine.Results SASI at 0?inser- tion angle was(7.81?1.28)mm and SAS2 at 10?insertion angle was(9.69?1.23)mm,with statisti- cal difference(P＜0.01).For SAS1,the distance from the midline of pedicle to the midline of posterior arch and the distance from the center of C2 inferior articular process to the midline of posterior arch showed insignificant statistical difference.However,the entry point at the posterior arch of the midline of SAS2 was located at 2.0 mm lateral to the midline of ASAI.Twenty-six pedicle screws in 13 cases were inserted correctly,without cortex breakage,or nerve and vessel injury.Conclusions There is a safe region for screw fixation in atlas lateral mass.Wider space available for the screw can be acquired when transverse angle is 10?.It is necessary to confirm the safe region by using axial CT of atlas before screw fixation.

Objective To explore the possibities of routine disinfection for prosthetic sockets. Methods From June to August, 2016, 19 lower limbs prosthesis wearers wiped their prosthetic socket surfaces and sprayed the stump socks with a compound of quaternary ammoni-um salt every night for three weeks. Meanwhile, field investigation and sampling were carried out weekly. Staphylococcus aureus, Pseudo-monas aeruginosa, Escherichia Coli and Candida albicans were isolated and identified, and colony counting was carried out. Results After disinfection, the number of bacteria on the prosthetic socket reduced 1.8-3.0 log, and the number of fungi reduced 1.6-1.9 log. One strain of Staphylococcus aureus and one strain of Escherichia Coli were isolated before disinfection and one strain of Pseudomonas aeruginosa was isolated after disinfection. Eczema and itching symptoms relieved or disappeared and deodorant effect was distinguished after continuous disinfection. Conclusion Disinfection on prosthetic sockets with compound of quaternary ammonium salt may control the microbial contam-ination and odor, reduce the incidence of eczema and other skin diseases.

OBJECTIVE: To observe the different tissue distributions of the adriamycin polybutylcyanoacrylate nanoparticle (ADM-PBCA-NP) in the mice body after the injection via lateral tail vein, and to study the liver targeting effects of ADM-PBCA-NP in different diameters on normal mice livers. METHODS: One hundred and eighty mice were randomly divided into 6 groups with 30 mice in each group: non-conjugated free ADM (Group 1); (22.3+/-6.2) nm in diameter ADM-PBCA-NP group (Group 2); (48.6+/-9.2) nm ADM-PBCA-NP group (Group 3); (101.9+/-20.3) nm ADM-PBCA-NP group (Group 4); (143.5+/-23.5) nm ADM-PBCA-NP group (Group 5), and (194.2+/-28.4) nm ADM-PBCA-NP group (Group 6). A single dose of either conjugated or free adriamycin equaled 2 mg/kg of body weight was delivered via the tail vein. Five mice in each trail were sacrificed at 5, 15, 30 minutes, 1, 5 and 12 hours after the injection, respectively. The adriamycin concentrations in the collected livers, kidneys, spleens, hearts, lungs and plasma were demonstrated using a high performance liquid chromatography with fluorescence detector. RESULTS: Compared with that of the control group, adriamycin was hardly detected in the heart muscles of the treatment groups (P<0.05). The nanoparticle-conjugated adriamycin was cleaned up quickly from the kidney tissues. The adriamycin concentrations of the mice liver and spleen in the experimental groups was significantly higher than those in the control group, except for the group with the nanoparticles diameters of (22.3+/-6.2) nm (P<0.05). The ADM-PBCA-NP in (101.9+/-20.3) nm diameter had the highest liver distribution, and the second highest adriamycin distribution in the liver was the group of (143.5+/-23.5) nm diameter (P<0.05). Adriamycin was released slowly in the liver during the detection period in the experimental groups. ADM-PBCA-NP in (22.3+/-6.2) nm diameter was not distributed in the tissues of the livers, kidneys, hearts, spleens, and lungs. CONCLUSION ADM-PBCA-NP with a 100 - 150 nm diameter range has the best liver targeting with slow medicine release. It also decreases the medicine distribution in the heart and other organs. In the treatment of liver cancer, the polybutylcyanoacrylate nanoparticle system has a good liver targeting ability, which increases the anticancer activity and markedly decreases the toxicity of adriamycin.
