Background The study on influences of gender,age and axial length (AL) on lens thickness (LT) and anterior chamber depth (ACD) in normal population is still lack in China.Objective This study was to measure LT and ACD in normal subjects and discuss their changes with age,gender and AL.Methods AL,ACD and LT were measured on 866 eyes of 433 normal population with Lenstar LS900 in Tianjin Eye Hospital from March through December in 2013,including 390 eyes in 195 males and 476 eyes of 238 females.ACD/AL,LT/AL and (ACD+LT)/AL were calculated after measurement.The subjects were grouped to the 10-20 years group,21-30 years group,31-40 years group,41-50 years group,51-60 years group and ≥61 years group based on age,or the 22 mm≤AL＜24 mm group,24 mm≤AL＜26 mm group and AL≥26 mm based on AL,and the measured parameters were compared and analyzed among the groups.Oral informed consent was obtained from each subject or child contutor prior to any medical examination.Results AL,ACD and LT values were (24.41±1.37),(2.89±0.42) and (4.05±0.52) mm in the males,and those in the females were (23.83±1.31),(2.72±0.40) and (4.20±0.44) mm,showing significant differences between them (t=6.278,6.102,-4.595,all at P=0.000).No significant differences were found in ACD,LT,ACD/AL,LT/AL and (ACD+LT)/AL values between the right eyes and the left eyes (t=-0.713,0.186,-0.754,0.296,-0.168,all at P＞0.05).As the increase of the AL,ACD was remarkable deepened but LT was declined,with the considerable difference among the 22 mm ≤ AL＜24 mm group,24 mm ≤ AL＜ 26 mm group and AL ≥ 26 mm group (F =176.640,94.569,both at P =0.000).ACD value was higher,but LT value was lower in the 24 mm≤AL＜26 mm group or AL≥26.00 mm group than that in the 22 mm≤AL＜24 mm group (all at P＜0.05).ACD value was gradually reduced,while LT value was elevated with aging,with significant differences among the different age groups (F =104.531,373.225,all at P =0.000).Significant correlations were found between age and ACD,LT or (ACD + LT)/AL,with the regression equations of ACD (mm) =-0.015 × age + 3.434 (F =-22.979,P =0.000);LT (mm) =0.024 × age + 3.122 (F =44.856,P =0.000),LT/AL =0.001 × age + 0.122 (F=37.982,P=0.000),(ACD+LT)/AL=0.001×age+0.259 (F=22.451,P=0.000).Conclusions Compared with normal females,males have thinner LT and deeper ACD.In the normal eyes,longer AL is,thinner LT is and the deeper ACD is.LT thickens and ACD deepens with aging.

The content of SO2 in Paeoniae Radix Alba (RPA) was determined by the method documented in Chinese Pharmacopoeia (CP) 2010 edition to validate the repeatability of the method for evaluating RPA, and the contents of paeoniflorin sulfonate in both the residual material and distilled solution of RPA were determined by HPLC to study the transformation of paeoniflorin sulfonate to SO2 by HCl. It was found that the repeatability of the method in CP for evaluating RPA is unacceptable, and paeoniflorin sulfonate was detectable in both the residual material and distilled solution of RPA even at "the end point" of SO2 determination, merely about 50% of paeoniflorin sulfonate was transformed to SO2 by HCl, indicating that the current SO2 determination method in CP is not able to accurately quantify SO2 in RPA. It is recommended that more special method for determining SO2 content in RPA should be developed regarding the chemical characteristics of sulfur-fumigated RPA.

An ultra-performance liquid chromatography-quadrupole/time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) combined with reference herb method was developed to rapidly screen commercial sulfur-fumigated ginseng. Sufur-fumigated ginseng reference herb was prepared using genuine ginseng by conventional procedure. Then the reference sulfur-fumigated ginseng sample was analyzed by UPLC-Q-TOF-MS/MS to identify characteristic marker components. 25-hydroxyl-Re sulfate with higher abundance was se- lected as marker compound from 8 characteristic components identified in sulfur-fumigated ginseng reference herb. The fragmentation of 25-hydroxyl-Re sulfate was extensively investigated, fragment ion m/z 879.44 with higher intensity was chosen as the characteristic ion of sulfur-fumigated ginseng. The response of ion m/z 879. 44 was improved by optimizing the MS conditions so that this ion could be used as the characteristic marker ion for screening purpose in ion extracting screening mode. The established approach was successfully applied to inspect 21 commercial ginseng samples collected from different cities in China It was found that the chemical profiles of 9 samples were similar to that of sulfur-fumigated ginseng reference herb, and the characteristic ion m/z 879. 44 of 25-hydroxyl-Re sulfate was also detected in these samples, suggesting that there were nearly 43% ginseng samples analyzed being sulfur-fumigated. This findng agreed well with the results of sulfur dioxide residues of these 21 commercial ginseng samples determined with the method documented in Chinese Pharmacopeia Compared with the method documented in Chinese Pharmacopeia, the proposed approach is more rapid and specific for screening sulfur-fumigated ginseng. SFDA of China should strengthen the enforcement to prohibit ginseng being sulfur-fumigated, so that ginseng and it preparations could be effectively and safely benefit to the health of human beings.

Objective:To analyze clinical characteristics of drug-induced hypersensitivity syndrome (DIHS) , and to compare the European, Japanese and Chinese diagnostic criteria.Methods:A total of 45 patients confirmedly diagnosed with DIHS according to the DIHS criteria originally proposed by Bocquet, were collected from the First Affiliated Hospital (Southwest Hospital) of Army Medical University between January 2009 and January 2019. Clinical data on the 45 patients were retrospectively analyzed, clinical characteristics were summarized and re-evaluated according to the European, Japanese and Chinese diagnostic criteria separately, and differences were analyzed in terms of the latency period, time to rash regression, eosinophil count, liver function indices, etc. One-way analysis of variance was used to compare means among multiple groups, and t test to compare means between two groups. Results:Of the 45 patients, 38 presented with eruptive drug eruptions, and 44 were accompanied by liver damage, 40 by elevated counts of peripheral white blood cells, 38 by eosinophilia, 21 by lymphadenectasis, and 4 by mucosal damage. Common culprit drugs included allopurinol (10 cases) , anti-tuberculosis drugs (7 cases) , cephalosporins (7 cases) , and Chinese medicine (4 cases) . Forty patients were treated with glucocorticoids, and 17 with glucocorticoids and intravenous gamma globulin. After treatment, 44 patients received improvement and 1 died. According to the European diagnostic criteria, there were 29 patients with suspected DIHS and 16 with confirmed DIHS; according to the Japanese diagnostic criteria, 37 patients could be confirmedly diagnosed with DIHS, but 8 could not be confirmedly diagnosed; according to the Chinese diagnostic criteria, 17 patients could be confirmedly diagnosed, but 28 could not be confirmedly diagnosed. According to the Japanese diagnostic criteria, the latency period was significantly longer in the patients with a confirmed diagnosis (36.91 ± 21.73 d) than in those without (20.00 ± 20.82 d, P = 0.04) . Conclusions:Common culprit drugs for DIHS include allopurinol, anti-tuberculosis drugs and cephalosporins. Most patients with DIHS are accompanied by liver damage, and the European diagnostic criteria are preferentially recommended for DIHS.

Objective To investigate the influence of abaI expression on acinetobacter baumannii biofilm formation.Methods Acinetobacter baumannii strain S isolated from bums patients was collected for the study,while the standard strain ATCC19606 was served as the control.At 6,24 and 48 hours,the gene expressions of abaI,pgaA,pgaB and pgaC were detected by real-time fluorescent quantitative PT-PCR,secretion of N-acyl-homoserine lactones (AHLs) by biological sensor and biofilm formation by MTT method.Results (1) Gene expressions of abaI,pgaA,pgaB and pgaC at 6 hours were 8.63 ±5.93,1.98 ± 1.93,1.01 ± 1.32 and 2.67 ± 3.46 respectively,which showed a quick increase at 24 hours (22.81 ± 17.60,5.13 ± 4.32,5.66 ± 3.97,11.97 ± 7.75 respectively),followed by a rapid decline in 48 hours (3.43 ± 0.88,1.30 ± 0.24,3.01 ± 3.00,3.02 ± 3.29 respectively).Gene expressions of pgaB and pgaC at 6 hours and that of pgaA and pgaC at 48 hours revealed statistically significant differences from those at 24 hours (P ＜ 0.05).(2) AHLs showed a level of 18.49 ± 11.03 at 6 hours,reached a peak of 52.23 ± 15.95 at 24 hours,then descended to 5.53 ± 0.94 at 48 hours.AHLs level at 24 hours showed statistically significant difference from that at 6 hours and 48 hours (P ＜ 0.05).(3)Biofilm formation at 24 hours and 48 hours was 2.83 ±0.44 and 2.71 ±0.15 respectively,far higher than that at 6 hours (0.49 ± 0.11,P ＜ 0.05).(4) In the correlation analysis among AHLs,biofilm formation and gene abaI,pgaA,pgaB and pgaC expressions,significant positive correlation was found between abaI and pgaA and between AHLs and pgaC expression (P ＜ 0.05).Conclusion Acinetobacter baumannii may regulate gene expressions of pgaA and pgaC responsible for biofilm formation to adjust to the external environment by means of changing abaI gene expression and AHLs secretion.
