AIM: To investigate the relationship between the levels of chemokine receptor 2(CXCR2)and basic fibroblast growth factor(bFGF)in aqueous humor and the prognosis of trabeculectomy in patients with acute primary angle-closure glaucoma(APACG).METHODS: A total of 80 cases(80 eyes)APACG patients who underwent trabeculectomy in our hospital from June 2020 to January 2022 were collected in the case group. According to the postoperative efficacy, they were grouped into a success group of 60 cases(60 eyes)and a failure group of 20 cases(20 eyes). Another 86 cataract patients(86 eyes)who underwent phacoemulsification with normal intraocular pressure in our hospital during the same period were included in the control group. Enzyme linked immunosorbent assay was applied to detect the levels of CXCR2 and bFGF in aqueous humor. ROC curve was applied to analyze the value of predicting trabeculectomy failure in APACG patients by the levels of CXCR2 and bFGF in aqueous humor. Furthermore, multivariate Logistic regression was applied to analyze the influencing factors of trabeculectomy failure in APACG patients.RESULTS: The levels of CXCR2 and bFGF in the aqueous humor of the case group were significantly higher than those of the control group(P<0.05). The levels of CXCR2 and bFGF in the aqueous humor of the failed group and the proportion of patients with postoperative shallow anterior chamber were significantly higher than those of the successful group(P<0.05). The AUC for predicting trabeculectomy failure in APACG patients using CXCR2 and bFGF levels alone and in combination was 0.885, 0.883 and 0.953, respectively. CXCR2 and bFGF were independent risk factors for trabeculectomy failure in APACG patients(P<0.05).CONCLUSION: The levels of CXCR2 and bFGF in the aqueous humor of APACG patients are obviously elevated, and both are risk factors for trabeculectomy failure.

Objective To explore the expression of TK1 in breast carcinoma and discuss its significance of carcinogenesis and progression in breast carcinoma and its relationship with Ki67. Method Using immunohistochemistry methods of SABC and S-P to detect the expression of TK1 and Ki67 in 89 cases of breast carcinoma tissue. Results Positive rate of TK1 in the breast carcinoma was 69.7% (62/89), and the expression of TK1 was significantly associated with lymph node metastasis, TNM stage and histological grade (P < 0.05), but it was not significantly correlated with age (P > 0.05). The expression of TK1 was not significantly correlated with Ki67 in the breast carcinoma (P>0.05). Conclusions Expression of TK1 is associated with carcinogenesis and progression, and it is a poor prognostic marker of breast carcinoma. TK1 and Ki67 are the indicators of cellular growth independently.

The function of salivary glands in patients with subacute thyroiditis was evaluated.The data of patients with subacute thyroiditis,primary hypothyroidism,and normal controls undergoing radionuclide scanning were reviewed and compared retrospectively.The ratio of target to non-target values in the salivary glands were decreased in patients with subacute thyroiditis.Thyroid and salivary glands in patients with subacute thyroiditis might be damaged simultaneously and both developed pharyngeal symptoms partly due to the damaged salivary glands.

This study is aimed to evaluate the clinical application of the millimeter wave and magnetism light compound therapy. The EHF-98B MMW. RL compound therapy apparatus made in the University of Electronic Technology(Chengdu) was used in 171 patients. The superficial, skin lesions or the visceral reflected skin regions (acupoints) were directly exposed to the light from the apparatus. All the cases were divided into five groups, namely skin mucosa superficial lesions, trauma of the bone and joint soft tissue, surgical incision, ENT infections, and rare intricate diseases. The therapeutic effects observed in the groups were analyzed and evaluated by means of 4 levels. As for the 171 patients, the cure rate was 42.7% (73 patients), the effective rate 25.1%(43 patients), the improvement rate 31%(53 patients), and no effect constituted 1.2%(2 patients). The total effective rate was 98.8%. This therapy was especially effective for treating chronic cervicitis, cervical erosion, soft tissue trauma, surgical incision. Also it was effective for treating some rare intricate diseases, e.g. sterility, vitiligo, Behcet disease. So the millimeter wave and magnetism light compound therapy may find wide clinical applications.

Objective To understand the etiological characteristics and risk factors of respiratory virus infection in children with bronchial asthma, and to provide theoretical basis for the prevention and treatment of respiratory virus infection in children with bronchial asthma. Methods A total of 374 children with bronchial asthma who were treated in Jianyang People's Hospital from December 2018 to December 2020 were enrolled. Pharyngeal swabs were collected from the outpatient children on the day of treatment, and 2 mL of nasopharyngeal secretions were collected from the hospitalized children within 24 hours by negative pressure aspirator. Seven viral antigens including RSV, ADV, IVA, IVB, PIVI, PIV II, and PIV III were detected. According to whether the virus test results were positive or not, they were divided into the experimental group (n=191) and the control group (n=183). Logistic regression analysis was used to screen the risk factors of respiratory virus infection in children with bronchial asthma. Results Among the 374 samples, the virus positive rate was 51.07% (191/374), and the top 3 virus species in the positive samples were RSV, ADV, and PIV III, accounting for 41.36% (79/191), 30.36% (58/191), and 9.42% (18/191), respectively. In addition, IVA accounted for 5.24% (10/191), PIV II accounted for 5.24% (10/191), PIVI accounted for 3.66% (7/191), and IVB accounted for 1.57% (3 /191). The positive rates of virus were 47.96% (94/196) and 54.49% (97/178) in male and female children, respectively, with no significant difference (χ²=1.597，P>0.05). The positive rate of 1~3 years old children was significantly higher than that of >3 years old group (χ²=6.412，P<0.05). There were significant differences in the frequency of asthma attack, intravenous glucocorticoid application and the onset season between the two groups (P<0.05). Further analysis showed that the frequency of asthma attack >3 times, intravenous glucocorticoid application and onset season were independent risk factors for respiratory virus infection in children with bronchial asthma (P<0.05). Conclusion The infection season of acute respiratory tract infection in children with asthma is mainly concentrated in autumn and winter, with RSV as the main viral pathogen. Targeted preventive measures should be given to children with bronchial asthma who have more than 3 asthma attacks and intravenous glucocorticoid application, which can reduce respiratory virus infection in children with asthma.

Objective To explore the relationship between glucose-6-phosphate dehydrogenase deficiency and type 2 diabetes and to provide reference for clinical diagnosis,monitoring and treatment of Type 2 diabetes.Methods Subjects were selected from our hospital,including 173 cases of healthy volunteers assigned to the control group;1 95 cases with type 2 diabetes conforming to the diagnostic criteria of WHO were assigned to the diabetic group.97 cases were diagnosed with glucose-6-phosphate dehydrogenase deficiency in our hospital,of whom 82 cases were assigned to simple glucose-6-phosphate dehydrogenase deficiency group,and 1 7 cases were assigned to the diabetes with glucose-6-phosphate dehydrogenase deficiency group.The correlation of glucose-6-phos-phate dehydrogenase activity and diabetes was measured by each detected value.Results Compared with the control group,the glu-cose-6-phosphate dehydrogenase activity and RBC count in diabetic group were higher(P <0.05).Positive correlations between glu-cose-6-phosphate dehydrogenase activity and RBC count in the two groups were significant(P <0.05).HbA1c and FBG showed a significant positive correlation in the control group,diabetic group and diabeties with glucose-6-phosphate dehydrogenase deficiency group(P <0.05).But there was no significant correlation in the glucose-6-phosphate dehydrogenase deficiency group.The rate of screening for glucose-6-phosphate dehydrogenase deficiency in diabetes group was 3.6%,and the rate in the control group was 1. 1%.When HbAlc≥6.5%,the rate of screening for glucose-6-phosphate dehydrogenase deficiency in the diabetes group was signifi-cantly higher than that in the control group (χ2 =4.239,P =0.039).Conclusion The level of HbA1c is discordant with that of blood glucose in diabetic patients with glucose-6-phosphate dehydrogenase deficiency group.Diabetes leads to the increasement of the rate of glucose-6-phosphate dehydrogenase deficiency.The glucose-6-phosphate dehydrogenase activity of diabetic patients with non-glucose-6-phosphate dehydrogenase dificiency is higher than that of the normal group.It may be associated with the level of RBC or increase of compensatory.Further more,glucose-6-phosphate dehydrogenase activity may be a good indicator for controlling diabetes,which remains to be further studied.

Objective To observe the effect of moxibustion on the learning ability and memory of rat models of Alzheimer’s disease (AD) and the expression of amyloidβ protein (Aβ)-42, interleukin (IL)-1β, and IL-2, for unveiling the function and mechanism of moxibustion in treating AD.Method Forty-eight healthy male Sprague-Dawley rats were randomized into a sham-operation group, a model group, a Western medication group, and a moxibustion group, 12 rats in each group. The AD model rats were established by injection of Streptozotocin (STZ) into bilateral ventricles. From the 10th day after the operation, the moxibustion group started to receive moxibustion at Baihui (GV 20), Mingmen (GV 4), Changqiang (GV 1), and Guanyuan (CV 4); meanwhile, the Western medication group received Donepezil hydrochloride via intragastric administration. After 30-day treatment, the learning and memory ability was tested by using water maze, the hippocampal Aβ-42 was examined by immunohistochemical method, and the expression of hippocampal IL-1β and IL-2 was by double-antibody sandwich ELISA.Result Compared to the model group, moxibustion significantly down-regulated the levels of Aβ-42 (P<0.05) and IL-1β protein (P<0.05), up-regulated the level of IL-2 protein (P<0.05) in hippocampus, and markedly improved the learning and memory of AD rats (P<0.05).Conclusion Moxibustion can enhance the immunity and learning ability, which is plausibly related to the down-regulation of IL-1β, up-regulation of IL-2, and improvement of Aβ-42 in hippocampus.

ObjectiveTo analyze the supplementary test results of HIV screening positive samples in Jianyang City, Chengdu from 2019 to 2022, to evaluate different HIV testing methods, and to provide a basis for the development of HIV testing strategies in the local area. MethodsWestern blotting (WB) supplementary test was conducted on 1 172 screening positive samples from the HIV confirmatory laboratory in 2019‒2022 according to the national technical specifications. The samples were tested by the rapid test, enzyme-linked immunoassay (ELISA), and chemiluminescence immunoassay (CLIA). The test results of the three HIV screening methods were collected and a database was established for statistical analysis. ResultsA total of 1 172 samples were tested through supplementary test, of which 1 022 samples were tested positive (87.20%), 75 were uncertain (6.40%), and 75 were negative (6.40%). The positive results of the three different HIV screening methods were consistent with the supplementary test. The rapid test had the highest positively supplementary rate of 88.54%, followed by ELISA of 86.98%, and CLIA of 85.92%. The difference was statistically significant (χ²=9.505, P<0.05). The detection rate of WB band patterns in positive samples were the highest at 100.00% for gp160 and gp120, and lowest at 50.68% and 63.41% for p55 and p17, respectively. The WB band patterns of uncertain samples were mainly gp120 (81.33%) and p24 (46.67%). Among the 75 uncertain samples, 39 were followed up and 29 of which turned positive, with a high positive conversion rate of 74.36%. ConclusionIt is necessary to directly add HIV nucleic acid testing to samples with positive WB supplementary test results and samples with uncertain WB supplementary test results in combination with CLIA, so as to avoid the spread of HIV infection caused by missed detections.
