Objective:To analyze the genetic mutation characteristics of glucose-6-phosphate dehydrogenase (G6PD) deficiency among infants in Kunming.Methods:A total of 15 533 infants (7 994 males and 7 539 females) born in Kunming from January 1, 2018, to December 31, 2020, with an age range of 2 to 44 days, were selected. G6PD enzyme activity and gene mutation types were detected using fluorescence quantitative analysis, multicolor melting curve analysis (MMCA), and Sanger sequencing. Droplet digital PCR (ddPCR) was used for quantitative analysis of a newly identified variant family to determine the mutant allele proportion in family members. Meanwhile,the protein structure model and pathogenicity prediction of the novel variant were analyzed.Data analysis was conducted using SPSS 26.0. Specifically, chi-square tests were used for the detection rates of G6PD enzyme activity and gene mutations between different genders. One-way analysis of variance (ANOVA) was used for the comparison of enzyme activity among different mutation types.Results:Among 15 533 infants, 143 cases (129 males and 14 females) were tested positive for G6PD activity, with a detection rate of 0.92% (143/15 533). The difference in detection rates between males and females was statistically significant (χ 2=96.76, P<0.001). Out of 89 enzyme activity-positive cases (83 males and 6 females) underwent genetic testing, 77 (72 males and 5 females) were detected by MMCAand other 12 negative samples were underwent further Sanger sequencing, revealing mutations in 6 samples, all of which were males. Among the 83 individuals with gene mutations, 78 had heterozygous mutations, 1 had a homozygous mutation, and 4 had compound heterozygous mutations. A total of 12 mutation types were detected, with G6PD c.487G>A, c.1024C>T, c.1388G>A, and c.1376G>T being the most common, accounting for 74.70% (62/83) of all mutation types. The average G6PD enzyme activity of c.1376G>T was the lowest, and the differences were statistically significant compared to the average enzyme activity of the other three mutations ( P<0.05). One male infant with a newly identified G6PD c.242G>C mutation was detected, predicted to be pathogenic. ddPCR confirmed that the mother of the affected child was a c.242G>C mutant chimera, with a chimera proportion of 6.66%. Conclusions:In the Kunming region, the predominant G6PD deficiency gene mutation is c.487G>A, with the detection of a novel G6PD c.242G>C mutation. The application of ddPCR technology can assist in detecting the proportion of mutation chimeras.

Objective To study the therapeutic effect of IGF?1R inhibitor TAE226 on malignant pleural effusion ( MPE) in nude mice. Methods Human lung carcinoma A549 cells were injected into the pleural cavity of nude mice to establish MPE model. The mice were randomly divided into model group and treatment group, and were orally administered with distilled water and TAE226 ( 20 mg/kg ) in the same volume, respectively. The volume of pleural effusion and tumor weight of the two groups were observed. HE staining was used to reveal the histological changes and enzyme?linked immunosorbent assay ( ELISA) was used to detect the IGF?1R protein expression. IGF?1R mRNA level in the tumor tissue was determined by RT?PCR. Microvessel density (MVD) and cell proliferation index (PI) were assessed by immunohistochemical analysis. The protein expression levels of IGF?1R, p?IGF?1R, PI3K and p?PI3K in the tumor tissue were determined by Western blotting. Results The volumes of pleural effusion were ( 241. 4 ± 89. 7 ) μl and (121.7±78.8) μl in the model and treatment groups, respectively (P<0.05). The tumor weight of treatment group was (316.7±186.3) mg, significantly lower than that of the model group (671.4±281.4) mg (P<0.05) . RT?PCR analysis showed that IGF?1R mRNA level was 0. 914 ± 0. 029 in the treatment group, significantly lower than that of the model group (1.152±0.037, P<0.01). The ELISA data revealed that IGF?1R protein expression level of the model group was significantly higher than that of the treatment group [(41.0±4.7) μg/L vs. (24.0±3.1) μg/L, P<0.01]. Immunohistochemical analysis showed that there were significant differences between MVD and PI in the model and treatment groups [ MVD, 34. 75 ± 3. 49 vs. 22.25±3.63;PI, (75.25±7.15)% vs. (45.75±5.12)%;P<0.01 for both). Western blot data showed that IGF?1R and PI3K protein expression levels were not significantly different between the model and treatment groups (1.03±0.33 vs. 0.98±0.37 and 1.05±0.28 vs. 0.98±0.19), respectively (P>0.05), but p?IGF?1R and p?PI3K protein expression levels had significant differences between the two groups (1.08±0.10 vs. 0.51± 0.08 and 1.12±0.09 vs. 0.86±0.09), respectively (P<0.01 for both). Conclusions The IGF?1R inhibitor can effectively inhibit the formation of malignant pleural effusion. Its mechanism may be related to the suppression of tumor cell proliferation, invasion and angiogenesis through inhibition of PI3K signaling. TAE226 treatment may be a potential therapeutic regimen of treating malignant pleural effusion.

Objective: To observe the effect of acupuncture plus LONG's manual manipulations on the functional improvement of the patients with lumbar intervertebral disc protrusion. Methods: 60 cases of the patients were randomly divided into a observation group and a control group, 30 cases in each group. The observation group was treated with acupuncture plus LONG's manual manipulations, and the control group was treated with single acupuncture. The functions of the lumber vertebrae were processed in accordance with the assessment system of Japanese Orthopedic Association (JOA), and the therapeutic effects were assessed by Visual Analog Scale (VAS). Results: After the treatments, the differences in JOA and improvement indexes were statistically significant (P<0.05) between the two groups. VAS was decreased much remarkably in the observation group (P<0.01) than before the treatments and decreased remarkably in the control group (P<0.05) than before the treatments. There was a remarkable difference in VAS between the two groups after the treatments (P<0.05).Conclusion: Acupuncture plus LONG's manual manipulations are better than single acupuncture in improving the functions of the patients with lumbar intervertebral disc protrusion.
