Background Selective laser trabeculoplasty (SLT) is one of common therapies for early-stage primary open angle glaucoma (POAG).However,it always been used as a method of treating medically uncontrolled open angle glaucoma in China.So the assessment of efficacy of SLT as the initial therapy for POAG is still lack.Objective This clinical study was to compare the efficacy of SLT in early-stage POAG eyes with or without primary medical therapy.Methods A prospective non-randomized controlled study was designed.Sixty-five eyes of 37 patients with early-stage POAG were divided into without pre-treated group (30 eyes of 16 patients) and with pretreated group (35 eyes of 21 patients).SLT was performed on the inferior trabecular meshwork of 180° in all the patients aged 12-57 years old using a 532 nm frequency-doubled,Q-switched Nd:YAG laser with the pulse 3 ns,spot diameter 400 μm.The emitting energy was set from an initial energy of 0.6 mJ to decreased energy successively at 0.1 mJ interval till bubbles coming out.The following-up was 6 months.Primary outcome of SLT included the changes of intraocular pressure (IOP) and effective rate,and the secondary outcome included the perimetry and C/D value.The safety index was evaluated as the incidence of irritative symptom.Results After SLT 1 day to 6 months,the IOP was lower than that before SLT in all the patients (all at P＜0.05).The IOP was (24.03± 3.76)mmHg and (19.18±3.86)mmHg respectively at preoperation and postoperative 1 month in without pretreated group,with a mean decreasing value of (4.85 ±4.31)mmHg,in with pretreated group,the IOP was (23.63±4.29)mmHg at preoperation and (17.07±4.15)mmHg at postoperative 1 month,with a mean difference of (6.28±3.57)mmHg,with a significant difference in the IOP lowing value between the two groups (P =0.045),but there were no significant differences in the IOP lowing value between without and with pretreated groups in 1 hour,1 day,3 months and 6 months after SLT (all at P＞0.05).The effective rate was 75.00％ and 76.67％ in without and with pretreated groups respectively at the end of following-up (P =0.882).No obvious changes were seen in visual field and C/D value before and after SLT in both groups.Also,no serious complication was found in the patients during the following-up duration.Conclusions SLT has a good outcome in lowing-IOP for early stage POAG.There is no obvious impact to the clinical efficacy of SLT whether with or without the primary administration of anti-glaucomatous eye drops.Long-term effect of SLT remains to be observed.

Objective To investigate the effect of Ulinastatin preconditioning on hyperthermia induced rat skeletal muscle injury and the possible mechanism. Methods Cultured skeletal muscle cells were divided into 7 groups: control group (Group C), as normal culture; hyperthermia treated group (Group H), in which cells were exposed to 42℃for 2 hours then transfered to normal culture; ulinastatin preconditioned group (Group U), which were only preconditioned 1 hour by the final concentration of ulinastatin at 1 250 U/mL; and four different concentration of ulinastatin preconditioned+hyperthermia treated groups (Group Ⅰ, Ⅱ, Ⅲ, Ⅳ), in which cells were preconditioned 1 hour by the final concentration of ulinastatin at 312 , 625, 1250, 2 500 U/mL, respectively. And then, all the four groups were exposed to 42℃for 2 hours. MTT assay and LDH leakage were performed to study the cytotoxicity. Superoxide dismutase (SOD) activity and malondialdehyde (MDA) formation were measured to reflect the activity of antioxidase. Results Compared with Group H, MTT value in ulinastatin preconditioned group in GroupⅠ, Ⅱ,Ⅲ, Ⅳsignificantly increased (P<0.05) LDH leakage significantly decreased (P<0.05). And the activity of SOD in cultured cells significantly increased (P < 0.05), the content of cellular MDA was also significantly decreased (P<0.05). But there were no significant difference among Group Ⅰ, Ⅱ,Ⅲ,Ⅳ(P>0.05). Conclusion Ulinastatin preconditioning may have protective effect against hyperthermia induced skeletal muscle injury and it may be related to its ability of inhibiting radical production and promoting radical scavenging.

Objective: To compare the effects of bare-handed cardiopulmonary resuscitation (CPR) and cardiopulmonary resuscitator in emergency treatment. Methods: A total of 185 patients received CPR in our hospital from 2013-01 to 2015-10 were enrolled. The patients were divided into 2 groups: Bare-handed CPR (Bare-handed ) group, n=101 and Cardiopulmonary resuscitator (Mechanical) group, n=84;meanwhile, taking 30 min as border time, each group was further divided as short time CPR subgroup and long time CPR subgroup. High quality CPR was conducted in all patients. The success rates, time and blood levels of lactic acid after CPR were compared among short time subgroup, long time subgroup between Bare-handed group and Mechanical group respectively. Results: For short time CPR patients, the success rates, time and blood levels of lactic acid after CPR were similar between Bare-handed group and Mechanical group; for long term CPR patients, the success rates and time were similar between Bare-handed group and Mechanical group, while blood levels of lactic acid after CPR in Mechanical group (6.88 ± 1.82) mmol/L was lower than Bare-handed group (9.39 ± 2.39) mmol/L, P<0.05. Conclusion: The success rates of bare-handed CPR and mechanical CPR were similar for emergency treatment, both methods were effective; while mechanical CPR may save the manual labor, achieve better metabolic result which should be recommended in clinical practice.

Objective To investigate the expression pattern of skeletal muscle specific miR-206,myogenesis related myoD which change with time in dcnervated muscle atrophy rats.Methods From June,2015 to January,2016,40 SPF sprague-dawley rats were equally classified into 5 groups randomly according to standard settled before,5 groups were separately defined as denervated 0d group,denervated 1d group,denervated 7d group,denervated 14d group,and denervated 28d group.Each group contained 8 rats.The rats atrophy models were established by cutting sciatic never on left side.According to the different denervated time,the gastrocnemii on both sides were obtained under anesthesia,respectively.The wet weight ratio of two compared gastrocnemii were measured,and the gastrocnemii transection was observed by HE stain,measured the expression of myoD protein by western blot,obtained the expression of miR-206,myoD mRNA by qPCR.Results According to our study on rats denervated atrophy models,the wet ratio of compared gastrocnemius would decrease rapidly,by HE stain,decease of cross sectional area in muscle fiber was observed as well as degeneration.Collagen fibers hyperplasia appeared and increased with time change.Wet ratio and transaction aera ratio of group Od,1d,7d,14d,28d were 0.99±0.04,0.92±0.07,0.68±0.11,0.39±0.06,0.27±0.07 and 0.99±0.02,0.96±0.04,0.51±0.09,0.34±0.08,0.23±０.03 respectively,difference between experimental groups and control group were statistically significant (P＜ 0.05),the differences between each experimental groups were also statistically significant (P＜ 0.05).After qPCR test of miR-206,myoD mRNA expression,it was found that their expression patterns were similar,miR-206,myoD mRNA increased at first and would reach the expression peak at the 7 th day,after that their contents decreased but still higher at the 14th day when compared with that at the 1 st day.Their expression of group 0d,1 d,7d,14d,28d were 0.24±0.06,0.34±0.04,0.68±0.04,0.49± 0.07,0.25±0.03 and 0.41 ±0.06,0.49±0.09,0.93±0.06,0.66±0.03,0.39±0.04,respectively.All experimental groups were statistically significant different when compared with 0d group except 1d group (P＜ 0.05),the differences between each experimental groups were also statistically significant(P＜ 0.05).The protein expression of myoD was also measured by western blot test,which showed nearly the same expression pattern as the mRNA expression pattern.After injury,the protein expression increased and reached the expression peak at the 7th day.The relative expression of myoD of group 0d,1d,7d,14d,28d measured by grey ratio were 1.03±0.05,1.06±0.06,1.42±0.10,0.66±0.13,0.24±0.07,respectively.The difference between experimental groups and control group were statistically significant (P ＜ 0.05),the differences between each experimental groups were statistically significant (P ＜ 0.05) as well.Conclusion The degree of muscle denervation atrophy was related to the denervated duration in rats.The expression regulation of miR-206 and myoD in gastrocnemius was similar during the muscle denervation atrophy,which suggesting having internal relationship between miR-206 and myoD.
