RESUMEN
Objective: To observe the efficacy and safety of Kangbingdu granules (KBD) in the treatment of influenza. Methods: A multicenter, randomized, double-blind, double-dummy, and positive-drug parallel control trial was conducted in 27 Grade â ¢A hospitals in China and the subjects were randomly assigned to the KBD test group or the oseltamivir phosphate capsule control group at a ratio of 1â¶1. 200 subjects were planned to be enrolled in each group. The experimental group was given KBD (18g each time, 3 times a day) and oseltamivir phosphate simulator orally, while the control group was given oseltamivir phosphate capsule (75 mg each time, twice a day) and KBD simulator orally for 5 days. The primary efficacy indicators included the remission time of major clinical symptoms and the time of complete defervescence. The secondary efficacy indicators included dosage of acetaminophen, the change of traditional Chinese medicine (TCM) syndrome score and the remission time of other important clinical symptoms. The efficacy of KBD in the test group and Oseltamivir phosphate control group were compared. Adverse events or adverse reactions were observed at the same time to evaluate the safety of KBD Granules. Results: A total of 393 subjects from 27 Grade â ¢A hospitals in China were enrolled. The experimental group included 195 subjects and 191 subjects (97.95%) completed the trial, While the control group included 198 subjects and 195 subjects (98.48%) completed the trial. There was no significant difference in the shedding rate and rejection rate between the two groups (P>0.05). In the Full Analysis Set (FAS), the mean age of the experimental group was (34.9±14.4) years old, with 83 males (42.78%). The mean age of the control group was (33.3±13.5) years old, with 78 males (39.59%). There were no statistically significant differences between the two groups in demographic data, physical examination, viral pathogen detection, total score of TCM syndromes and scores of each symptom at baseline (P>0.05). In the FAS, the remission time M (Q1, Q3) of major clinical symptoms was 3.0 (3.0, 4.0) days in the experimental group and 3.0 (3.0, 4.0) days in the control group, and the difference was not statistically significant (P>0.05). The time M (Q1, Q3) of complete defervescence was 34.0 (20.3, 49.0) hours in the experimental group and 36.5 (19.6, 48.8) hours in the control group, and the difference was not statistically significant (P>0.05). KBD granules had the same effect as Oseltamivir phosphate capsule (P>0.05) in terms of acetaminophen dosage, TCM syndrome effect and disappearance rate of most important clinical symptoms. Meanwhile, the disappearance rate of dizziness and chest distress on day 3 in the KBD granules group was better than that of oseltamivir phosphate capsule (P<0.05). Conclusion: KBD granules have the same efficacy as Oseltamivir Phosphate capsule in the treatment of influenza and the drug safety is good.

To evaluate the efficacy of nasal continuous positive airway pressure (CPAP) on patients with obstructive sleep apnea syndrome, 20 patients with moderate to severe obstructive sleep apnea syndrome (respiratory disturbance index greater than or equal to 20) were studied. The patients were evaluated using the Grass polysomnograph model 78 during an overnight sleep one to two weeks apart with and without a nasal CPAP produced by 10 to 15 cm of water. The results showed that nasal CPAP significantly reduced the respiratory disturbance index (RDI) (p less than 0.001) and the desaturation index (p less than 0.001), and significantly raised the lowest oxygen saturation level. Nasal CPAP not only reduced RDI, but also improved the respiratory patterns during obstructive apnea events by shifting the obstructive apnea events to hypopnea events. Nasal CPAP also significantly decreased the relative time spent in stage 1 NREM sleep (p less than 0.001), and increased the relative time spent in stages 3+4 NREM and REM sleep (p less than 0.05). Most of the patients also felt better the morning after using nasal CPAP. Nasal CPAP significantly reduced the frequency and duration of apnea and the degree of nocturnal oxygen desaturation, and improved the respiratory patterns during obstructive apnea events, as well as the sleep architecture in obstructive sleep apnea patients. We conclude that nasal CPAP is effective in moderate to severe obstructive sleep apnea syndrome patients.

PURPOSE: To evaluate the position of iris-claw phakic intraocular lens (ICPIOL) in highly myopic eyes by Scheimpflug photography (SP) and ultrasound biomicroscopy (UBM). METHODS: Nine eyes of five patients aged 31+/-10 years with average spherical equivalent of -16.04+/-5.46 D (range -7.88 to - 22.88 D) were enrolled in this prospective study and implanted with Verisyse ICPIOLs (AMO). The anterior segment was evaluated by SP and UBM preoperatively and for at least 1 month postoperatively. The statistical significance may be questionable due to the limited number (nine) of eyes. RESULTS: By SP and UBM, the distance between corneal endothelium and lens (anterior chamber depth) preoperatively was 3.10+/-0.14 and 3.07+/-0.11 mm, respectively; between ICPIOL and corneal endothelium (pseudo-anterior chamber depth), 1.88+/-0.09 and 1.99+/-0.12 mm, respectively; between lens and posterior surface of ICPIOL (IL), 0.76+/-0.13 and 0.67+/-0.06 mm, respectively; between superior optic edge and iris (SOEI), 0.23+/-0.23 and 0.58+/-0.24 mm, respectively; between inferior optic edge and iris (IOEI), 0.07+/-0.13 and 0.41+/-0.22 mm, respectively; between ICPIOL haptics and the angle of anterior chamber (HA), 0.90+/-0.17 and 1.45+/-0.13 mm, respectively. ACD was well correlated between the two methods, but PACD, IL, OEI, HA were not. The postoperative measures, except IL, were significantly different between the two methods. CONCLUSION: The differences between measurements by SP and UBM reveal the ICPIOL's position variations with change of body position. Nevertheless, it seems adequate that space is maintained between ICPIOL and corneal endothelium, angle, and crystalline lens. The ICPIOL implanted in phakic eyes seems a safe alternative for treatment of high myopia.
