or older during the outbreak epidemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant in Sanya City, Hainan Province, August-September 2022, and to provide scientific and effective basis for formulating strategies for the prevention and treatment of COVID-19 in the elderly in the future. Methods　The data of 1 785 COVID-19 cases aged ≥60 years reported from August 1 to September 8, 2022 in Sanya City, and 537 local COVID-19 inpatients aged ≥60 years treated in Sanya Central Hospital were collected and analyzed using WPS Office 2018 software for data cleaning, database assistance, and drawing, and SPSS 22.0 software was used to statistically describe and analyze the counting data. Results　A total of 1 785 local COVID-19 cases aged ≥60 years were reported in China's Disease Prevention and Control Information System, including 1 509 confirmed cases (84.54%) and 276 asymptomatic cases (15.46%). Of the confirmed cases, 1 448 were mild cases (95.96%), 40 were common cases (2.65%), 10 were severe cases (0.66%), and 11 were critical cases (0.73%), and no deaths were reported. The ratio of male to female was 0.88∶1. The youngest was 60 years old, the oldest age was 107 years old, with a median age of 67 years old. Most of them (1 559 cases, 87.34%) were non-social employed personnel. Among them, 952 (53.33%) were from Tianya District and 733 (41.06%) from Jiyang District. Among the 537 COVID-19 elderly infected patients hospitalized in Sanya Central Hospital, infected patients with underlying diseases accounted for 287 (53.45%) cases of hypertension, diabetes and other types of basic diseases (chronic kidney disease, hyperlipidemia, chronic gastritis, gastric ulcer, etc.), and there were serious infections. Conclusions　Most of the elderly infected with Omicron variants were mild cases with few symptoms, but the elderly infected with Omicron variants were difficult to recover or even worsen the condition due to old age and underlying diseases. Therefore, by analyzing the various aspects of elderly infected cases, scientific and effective basis can be provided to prevent and control the epidemic situation in the future, and reduce the occurrence of severe, critical and death cases of COVID-19 in the elderly.

OBJECTIVEto investigate the changes of γ-aminobutyric acid (GABA) and glutamate (Glu) in the cerebral cortex following acute bromoxynil intoxication in mice and the protective effect of sodium dimercaptopropane sulfonate (Na-DMPS).

METHODS30 ICR mice were randomly divided into blank control group (10), exposure group (10) and Na-DMPS protection group (10). The levels of GABA and Glu in the cerebral cortex were measured by RP-HPLC. The glutamine (Gln) level and the glutamine synthetase (GS), glutamate decarboxylation enzyme (GAD), γ-aminobutyric acid transaminase (GABA-T) activity in the cerebral cortex were determined by UV colorimetric.

RESULTScompared with the control group [GABA: (3.41 ± 0.12) micromol/g, Glu (14.00 ± 0.16) micromol/g, Gln (1.25 ± 0.19) micromol/g, GAD (13.50 ± 0.25) micromol × g(-1) × h(-1), GABA-T (25.51 ± 0.21) micromol × g(-1) × h(-1), GS(142.19 ± 1.31) U/mg pro], the level of GABA [(3.14 ± 0.14) micromol/g] was decreased (P < 0.05), whereas the level of Glu [(17.54 ± 0.40) micromol/g] and Gln [(3.35 ± 0.27) micromol/g] were increased (P < 0.05), the activity of GAD [(11.93 ± 0.15 micromol × g(-1) × h(-1)], GABA-T [(24.15 ± 0.22) micromol × g(-1) × h(-1)], GS [(140.75 ± 1.01) U/mg pro] was decreased (P < 0.05) in acute intoxication group; Compared with the acute intoxication group, the level of GABA [(3.52 ± 0.30) micromol/g] was increased (P < 0.05), whereas the level of Glu [(14.20 ± 0.32) micromol/g] and Gln [(1.32 ± 0.17) micromol/g] were decreased (P < 0.05), the activity of GAD [(13.01 ± 0.45 micromol × g(-1) × h(-1)], GABA-T [(25.19 ± 0.26) micromol × g(-1) × h(-1), GS [(142.35 ± 1.20) U/mg pro] was increased (P < 0.05); In contrast, the levels of GABA, Glu, Gln and the activity of GAD, GABA-T, and GS in Na-DMPS protection group were not significantly different in comparison with control group (P > 0.05).

CONCLUSIONthe central toxic effects of mice with acute bromoxynil intoxication may be related to the changes of GABA and Glu content in the cerebral cortex;Na-DMPS can protect mice from bromoxynil-induced central toxic effects and GABA and Glu abnormal change in the cerebral cortex.

The pathogenesis of some autoimmune diseases has been considered to be related to abnormal differentiation of T cell subsets. This study was aimed at investigating the change of Th1-like and Th2-like cells balance in ITP children, and analyzing the role of T cell subsets disequilibrium in the pathogenesis of ITP. Peripheral blood T cells were collected from 30 ITP patients, the T-cells were isolated and purified. The ratios of Th/Tc, Th1/Th2 and Tc1/Tc2 in peripheral blood T cells were analyzed by immunofluorescence staining and bicolor flow cytometry (FCM) in vitro. The results showed that as compared with the ratios of Th1/Th2 (48.76% +/- 6.17%) and Tc1/Tc2 (18.90% +/- 4.12%) in healthy children, the ratios of Th1/Th2 (56.21% +/- 5.95%) and Tc1/Tc2 (23.09% +/- 3.31%) in ITP children increased obviously. FCM analysis revealed that average percentages of Th, Th1, Th2, Tc, Tc1 and Tc2 were 22.31% +/- 6.51%, 21.92% +/- 6.42%, 0.39% +/- 0.14%, 31.12% +/- 6.15%, 30.95% +/- 5.45% and 1.34% +/- 0.84% in ITP children versus 39.24% +/- 5.82%, 39.01% +/- 5.47%, 0.80% +/- 0.16%, 30.25% +/- 5.63%, 28.72% +/- 5.20% and 1.52% +/- 0.68% in healthy children. The average percentages of Th, Th1 and Th2 decreased obviously, while the average percentages of Tc, Tc1 and Tc2 did not change. It is concluded that the ratios of Th1/Th2 and Tc1/Tc2 in peripheral blood T cells increase obviously in ITP children and the cellular immunity in ITP children shifts to Th1 type immunity superiority, which suggest that the abnormal differentiation of T cell subsets may play an important role in the pathologic process of ITP.

This study was aimed to investigate the effect of 1,4-benzoquinone (1,4-BQ) on growth of myeloid progenitor cells with IFN-gamma different genotypes and to compare its differences. Polymerase chain reaction (PCR) was used to amplify the polymorphism gene segment of IFN-gamma +874 A/T in 36 cord blood (CB) specimens. The specimens were divided into three groups (AA, AT and TT group). MNCs were planted on complete methylcellulose medium containing different concentrations of 1,4-BQ. The colony-forming units (CFU) were assayed, the differences of colony growth in specimens with different genotypes (AA, AT and TT) under 1,4-BQ exposure were analyzed. The results showed that frequencies of AA, AT and TT genotypes were 5.56%, 88.89% and 5.56% in the 36 CB samples respectively. Comparing colony numbers of IFN-gamma +874 AA, AT and TT genotype indicated that there was significant difference (p(AA) = 0.033, p(AT) = 0.009, p(TT) = 0.001, < 0.05). Significant cytotoxicity was observed after exposure to concentrations of 1,4-BQ > or = 5 micromol/L. Cytotoxic response of 1,4-BQ was dose-dependent. Under the same concentration of 1,4-BQ, there were no significant differences in capacity of cell colony growth between 3 groups (AA, AT and TT). Colony numbers of specimen No 3 in AT group and specimen No 2 in TT group were less than those of other specimens significantly. It is concluded that the hematopoietic myeloid progenitor cells cultured in the presence of 1,4-BQ show a dose-dependent cytotoxic response, but there are no significant differences in colony growth of IFN-gamma different genotypes (AA, AT and TT) under the same concentration of 1,4-BQ.

Objective To observe the stability of intraocular lens (IOL) in primary angle-closure glaucoma by ultra-long scan depth spectral domain optical coherence tomography (UL-OCT) after the phacoemulsification.Methods Totally 42 patients (42 eyes) with primary closed-angle glaucoma (PACG) and age-,gender-matched 40 patients (40 eyes) with age-related cataract were included in the study.All of patients underwent phacoemulsification combined with softec HD IOL implantation.Images were obtained by UL-OCT in 1 week,1 month and 3 months after the surgery for the calculation and analysis of the IOL decentration,tilt and the space between IOL and posterior capsule (IOL-PC space).And finally the intergroup differences at the different time-points were compared with the independent sample t test.Results The IOL decentration after 1 week,1 month and 3 months was (0.182 ± 0.054) mm,(0.232 ±0.081)mm,(0.183 ±0.089) mm in the PACG group,and (0.342 ± 0.141)mm,(0.288 ±0.110)mm,(0.249 ± 0.132)mm in the ARC group.There was statistically significant difference in IOL decentration 1 week after surgery between the two groups (P =0.006),but the differences in this variable at the other two time-points between the two groups were not statistically significant (both P ＞ 0.05).The tilt on the vertical axis at 1 week,1 month and 3 months after surgery was (3.670 ± 6.610) °,(-0.940 ± 4.730) °,(0.540±9.510)° in the PACG group,and (-4.090±7.610)°,(-5.100±5.530)°,(-1.430 ± 8.800) ° in the ARC group.The tilt on the vertical axis of the PACG group was less than that of the ARC group at 1 week after surgery,with statistical difference (P =0.025),but there was no significant difference in this variable at the other two time-points (both P ＞ 0.05).Moreover,the tilt on the horizontal axis showed no statistically significant differences (all P ＞ 0.05).The IOL-PC space on horizontal axis at 1 week,1 month and 3 months after surgery was (0.111 ±0.091)mm2,(0.044 ±0.066)mm2,(0.055 ±0.055) mm2 in the PACG group,and (0 176 ±0.213) mm2,(0.255 ±0.303) mm2,(0.059 ± 0.066) mm2 in the ARC group.The IOL-PC space on horizontal axis of the PACG group was less than that of the ARC group at 1 month after surgery,with statistical difference (P =0.045),but there was no significant difference in this variable at the other two time-points (both P ＞ 0.05).Moreover,the IOL-PC space on vertical axis showed no statistically significantdifferences (all P ＞ 0.05).Conclusion The stability of Softec IOL in the PACG group is better than that in ARC group in 3 months after phacoemulsification.

Objective To analyze the drug resistance profile of the clinical isolates of Candida albicans and establish a randomly amplified polymorphic DNA (RAPD) assay for Candida albicans. Methods Thirty strains of Candida albicans were collected from the intensive care unit (ICU) of the department ofneurosurgery between May, 2007 and November, 2007. The drug resistance of Candida albicans was analyzed with liquid microdilution method, and the fungal DNA was extracted for genotyping by RAPD assay. Results The sensitivity of Candida albicans strains was 100% to the anti-fungal drug VRC, 100% to AMB (100%), 96.35% to FCZ, 93.0% to 5-FC, and 90.0% to ITR. The 30 Candida albicans strains were genotyped into 27 types with a typing rate of 90.0%. Conclusion AMB and VRC remain the primary options for treatment of Candida albicans infection, and the isolated Candida albicans strains are highly sensitive to FCZ, 5-FC, and ITR. No evidence has been identified to suggest a local outburst ofCandida albicans infection in our hospital between May, 2007 and November, 2007.

The aim of this study was to investigate whether the single nucleotide polymorphism (SNP) of interferon-gamma (IFN-gamma) +874 T/A correlates with aplastic anemia. Amplification refractory mutation system-polymerase chain reaction was used to amplify the polymorphism gene segment of IFN-gamma +874 A/T from 54 aplastic anemia patients and 51 healthy adults. The results showed that the frequency of IFN-gamma +874 TT genotype and T allele was significantly higher in patients with aplastic anemia than that in the healthy adults (42.6% vs 17.6%, chi2=13.780, p=0.01; 65.7% vs 39.2%; chi2=14.811, p<0.001). In conclusion, IFN-gamma +874 A/T gene polymorphism is correlated with the susceptibility of aplastic anemia, but not significantly correlated with the the severity of aplastic anemia.
