Abstract: Objective　To analyze the clinical characteristics of Chlamydia psittaci pneumonia and improve the diagnosis and treatment skills of clinicians on this disease. Methods The clinical data of thirty-nine Chlamydia psittaci pneumonia cases detected by metagenomic next-generation sequencing (mNGS) from September 2020 to January 2022 at the Affiliated Hospital of Southwest Medical University were retrospectively analyzed. Results There was a history of poultry exposure in 89.7%(35 cases) of the patients. The most common clinical manifestations were high fever (92.3%, 36), cough (76.9%,30), muscle soreness (48.7%,19), headache (38.5%,15), etc. Laboratory examinations showed 76.9% of patients had a normal leukocyte count, and 76.9% had decreased lymphocyte count, often accompanied by elevated C-reactive protein (100%), procalcitonin (97.4%), interleukin-6 (95.8%), interleukin-10 (95.8%), alanine aminotransferase (74.4%), and aspartate aminotransferase (84.6%). Univariate analysis indicated that there were statistically significant differences in the levels of aspartate transaminase, blood urea nitrogen, C-reactive protein, and procalcitonin between severe pneumonia patients and non-severe pneumonia patients（P<0.05）. Multivariate logistic regression analysis showed that an elevated blood urea nitrogen (OR=4.899) had guiding significance for predicting the occurrence of severe pneumonia. Bronchoscopy examination showed no abnormalities in 53.6% of the patients. The imaging manifestations of pulmonary lesions were mainly lobar pneumonia (61.5%) and air bronchograms (94.9%). Therapeutically, it was sensitive to tetracyclines, macrocyclic lactones, and fluoroquinolones. A total of 84.6%(33 cases) of the patients were cured and discharged from the hospital at the end of the treatment. Conclusion Chlamydia psittaci pneumonia is a zoonotic disease that can be detected by mNGS. An elevated blood urea nitrogen level has guiding significance for predicting the occurrence of severe pneumonia. Empirically-selected regimens based on doxycycline are effective for the treatment of Chlamydia psittaci pneumonia.

Objective To explore the relationship between age and refractive predictability of excimer laser in situ keratomileusis (LASIK)for the correction of myopia.Design Retrospective case series.Participants 362 patients(703 eyes)who had performed LASIK.Methods According to the age,patients were divided into four groups(≤30y,31～34y,35～39y and≥40y).Their preoperative and postoperative refractive powers examined with automatic refactor as well as manifest optometry were analysed and followed up from 6 months to 2 years.According to pre-operative refractive power,patietns were divided into low and moderate myopia group(≤-6.00D), high myopia group(-6.25～-12.00D)and super-high myopia group(≥-12.25D).The eyes with refractive power at post-operative 2 years≥-1.00D were regressive eyes.Main Outcome Measures Refractive error before surgery,intended residual refractive power and 3,6, 12, 24 months post-operative refractive powers.Results There were no significant differences between intended residual refractive powers and refractive powers at post-operative 6 month in 3 groups(

Polydatin is a monocrystaline compound isolated from Polygonum cuspidatum Sieb. et Zucc. (Polygonaceae) with biological properties, such as anti-inflammation, anti-oxidative and nephroprotective effects. Increasing number of studies have demonstrated the protective effect of polydatin on renal ischemia reperfusion injury. However, the possible mechanisms of this protection are not fully elucidated. This study aimed to investigate the effect of polydatin on ischemia-reperfusion induced expression of toll-like receptor4 (TLR4) in rat renal tubular epithelia cells (NRK-52E), and analyze the mechanism of polydatin on TLR4 signal pathway. The cultured NRK-52E cells were incubated in three gas incubators for a period of 6 h at hypoxia and 24h at reoxygenation to simulate the ischemia-reperfusion injury in vitro. TLR4 mRNA level was analyzed by real-time-PCR, and the protein expression of TLR4 and NF-κB by Western blotting, while TNF-α and IL-1β proteins expressions were detected by ELISA. Polydatin downregulated I/R induced mRNA and protein expressions of TLR4, and decreased the protein expression of NF-κB, TNF-α and IL-1β. The TLR4 blocker partially antagonized the effect of I/R on NF-κB signaling, and such inhibitory effect was markedly enhanced by polydatin. In the present study, polydatin protects NRK-52E cells from I/R injury possibly by relieving the inflammatory response through regulation of TLR4/NF-κB signaling pathway.
