ObjectiveTo construct a group-based trajectory model (GBTM) for early medication adherence check-in, and to analyze the relationship between different trajectories and treatment outcomes in tuberculosis patients using data that were generated from smart tools for monitoring their medication adherence and check-in. MethodsFrom October 1, 2022 to September 30, 2023, a total of 163 pulmonary tuberculosis patients diagnosed in Fengxian District were selected as the study subjects. The GBTM was utilized to analyze the weekly active check-in trajectories of the subjects during the first 4 weeks and establish different trajectory groups. The χ² tests were employed to compare the differences between groups and logistic regression analysis was conducted to explore the relationship between different trajectory groups and treatment outcomes. ResultsA total of four groups were generated by GBTM analyses, of which a low level of punch card was maintained in group A, 6% of the drug users increased rapidly from a low level in group B, 17% of drug users increased gradually from a low level in group C, and 18% of drug users maintained a high level of punch card in group D. The trajectory group was divided into two groups according to homogeneity, namely the low level medication punch card group (group A) and the high level medication punch card group (group B, group C, and group D). The results of multivariate logistic regression analyses revealed that low-level medication check-in (OR=3.250, 95%CI: 1.089‒9.696), increasing age (OR=1.030, 95%CI: 1.004‒1.056), and not undergoing sputum examination at the end of the fifth month (OR=2.746, 95%CI: 1.090‒7.009) were significantly associated with poor treatment outcomes. ConclusionThe medication check-in trajectory of pulmonary tuberculosis patients within the first 4 weeks is correlated with adverse outcomes, or namely consistent low-level medication adherence check-ins are associated with poor treatment outcomes, while high-level medication adherence check-ins are associated with a lower incidence of adverse outcomes.

ObjectiveTo observe the effect of gene mutation on the effectiveness of arsenic-containing Chinese herbal compound formulas in the treatment of myelodysplastic syndromes （MDS） of different traditional Chinese medicine （TCM） patterns， so as to provide the basis for the clinical application. MethodsClinical data of 442 MDS patients who were treated with arsenic-containing herbal compound formulas were retrospectively collected， including the baseline demographic and clinical characteristics of the patients. Based on the TCM four examinations， the patients were divided into the spleen-kidney deficiency group as well as the qi-yin deficiency group， and according to the results of the next-generation sequencing （NGS） test， they were divided into the group with and without gene mutation respectively. The influence of gene mutation on the clinical effectiveness of patients with different TCM patterns was analyzed， the baseline demographic and clinical characteristics of the patients with different outcomes of the two TCM patterns were compared， and multivariate Logistic regression analysis was conducted on the influencing factors of the effective rate of MDS patients with gene mutation. ResultsA total of 190 cases were included in the spleen-kidney deficiency group （119 cases with gene mutation） and 43 cases in the qi-yin deficiency group （23 cases with gene mutation）. No statistically significant differences were noted in effectiveness assessment， total effective rate， and total response rate between the spleen-kidney deficiency group and the qi-yin deficiency group （P＞0.05）. In the spleen-kidney deficiency group， the total effective rate of MDS with gene mutation was 65.55% （78/119）， which was lower than 80.28% （57/71） of MDS without gene mutation， with statistical significance （P = 0.033）， while no statistical differences in effectiveness assessment and total response rate were noted （P＞0.05）. In the qi-yin deficiency group， no statistical differences were observed in effectiveness assessment， total effective rate， and total response rate of the patients in with or without gene mutation （P＞0.05）. In the spleen-kidney deficiency group with gene mutation， the rate of complex karyotype （P = 0.031） and the mutation rate of CBL gene （P = 0.032） in the ineffective population were higher than those in the effective population， while the mutation rate of DDX41 gene in the effective population was higher than that in the ineffective population （P = 0.033）. No statistically significant differences were found in other gene mutations， age， gender distribution， number of gene mutations， bone marrow hyperplasia degree， blast cell range， reticular fiber tissue proliferation or not， and prognosis of chromosomal abnormalities between the effective and ineffective populations （P＞0.05）. In the qi-yin deficiency group with gene mutation， no statistically significant differences were found in various items between populations with different outcomes （P＞0.05）. Multivariate Logistic regression analysis showed that complex karyotype， CBL mutation， and DDX41 mutation were independently associated with the effective rate of MDS with spleen-kidney deficiency and gene mutation （P＜0.05）. DDX41 mutation was an independent protective factor in the spleen-kidney deficiency group （OR＞1）， while complex karyotype and CBL mutation were independent risk factors （OR＜1）. ConclusionThe arsenic-containing TCM compound formulas exhibited better effectiveness in MDS with spleen-kidney deficiency pattern without mutation； and in MDS with spleen-kidney deficiency pattern without complex karyotypes， CBL mutation， and with DDX41 mutations. Furthermore， DDX41 mutation was an independent protective factor in the spleen-kidney deficiency group， while complex karyotype and CBL mutation were independent risk factors. In MDS with qi-yin deficiency pattern， gene mutation-related factors showed no significant impact on the effectiveness of arsenic-containing TCM compound formulas.

Objective To provide references,this study investigated the clinical characteristics of patients with non-syndromic oligodontia.Methods The information of 178 patients with oligodontia was collected,including histories,oral examinations,and panoramic radiographs.Tooth agenesis characteristics were calculated and evaluated.All the data were statistically analyzed with SPSS 24.0 software.Results No significant difference in the number of missing teeth was found between sexes nor between the right and left sides,and congenitally missing teeth affected the maxillary arch(P<0.05).The highest prevalence of tooth agenesis was observed in the mandibular second premolars.In the maxillary arch,the most common pattern of tooth agenesis was agenesis of the bilateral first and second premolars.The agenesis of the bilateral second premolars was observed in the mandibular arch.The prevalence of a symmetric pattern between the right and left quadrants was significantly higher than that of matched patterns between the maxillary and mandibular an-tagonistic quadrants.Approximately 16.85%of patients with nonsyndromic oligodontia were affected by other tooth-re-lated anomalies.Conclusion The common patterns of tooth agenesis were successfully identified in patients with non-syndromic oligodontia.Dentists need to provide multidisciplinary treatments for patients with nonsyndromic oligodontia because of variations in occluding and full-mouth tooth agenesis patterns.

Objective:To investigate the changes in structural brain network topology and microstructural damage in patients with multiple sclerosis (MS), and to analyze its correlation with cognitive function.Methods:Clinical and imaging data of 114 patients with MS (MS group) diagnosed in the First Affiliated Hospital of Chongqing Medical University from May 2021 to September 2022 were analyzed retrospectively. In addition, 71 volunteers were recruited as a healthy control group (HC group) during the same period. All subjects were performed on cognitive assessment and 3D-T 1 magnetization-prepared rapid gradient echo, 3D-fluid-attenuated inversion recovery, and diffusion kurtosis imaging (DKI) scans. GRETNA software was used to obtain network topology attributes, and global attributes included global efficiency, local efficiency, and small-world attributes [clustering coefficient(Cp), shortest path length(Lp), normalized Cp(γ), normalized Lp, and small-world index (σ)]. Local attributes included betweenness centrality (BC), degree centrality (DC), nodal clustering coefficient (NCp), nodal efficiency, nodal local efficiency (NLe) and nodal shortest path length. The DKI parameter map generated by the post-processing software was used to extract the DKI parameter values of the brain region with abnormal local topology of the brain structure network. The differences of global attributes, local attributes and DKI parameter values [kurtosis fractional anisotropy (KFA), mean kurtosis (MK), radial kurtosis (RK) and axial kurtosis (AK) values] were analyzed by independent sample t-test or Mann-Whitney U test, and corrected by false discovery rate (FDR). Spearman or Pearson correlation analysis was used to evaluate the correlation between abnormal brain structure network topology attributes and cognitive scale scores in the MS group. Results:Both the MS group and the HC group structure network showed small-world attributes, and the γ and σ values of the MS group were significantly lower than those in the HC group (FDR correction, P<0.05). Compared with the HC group, BC, DC, NCp and NLe broadly reduced in the MS group, mainly involving in bilateral frontal, temporal, precuneus, amygdala, and thalamus (FDR correction, P<0.05). After FDR correction, compared with the HC group, the KFA, MK, RK and AK values of 23 brain regions with abnormal local attributes of the network in the MS group were significantly changed in several brain regions (FDR correction, P<0.05). The correlation analysis showed, after FDR correction, the DC value of the right putamen in MS patients was positively correlated with the digit span test (DST) scores ( r=0.318 ,P=0.001). Conclusion:There are extensive changes in the structural brain network of MS patients, accompanied by varying degrees of microstructural damage, and the reduction of degree centrality in the basal ganglia putamen region is associated with cognitive impairment.

Objective: To evaluate the effect of vertical incision with superomedial pedicle for the treatment of female asymmetric hypermastia. Methods: The total of 31 patients with asymmetric breast hypertrophy were admitted from May 2012 to November 2018. All patients were female with an average age of 37.8 (28-55) years. Mammoplasty was performed by vertical incision with superomedial pedicle. According to the preoperative design, the epidermis of the pedicle, the excess skin and glandular tissue were removed. The superomedial pedicle was rotated upward and to be fixed on the major pectoralis fascia. After the fixation of the nipple areola, the incision was closed. Results: The mean follow up was (8.4±3.0) months, with a range from 6 to 18 months.One patient was unsatisfied with scar hyperplasia. One patient had slight mastoptosis 6 months after operation and received favorable outcome after revision. The rest of 29 patients had satisfactory results. Conclusions For patients with asymmetric breast hypertrophy, the new location of nipples on both sides should be determined by the degree of mastoptosis and hypermastia. So that, symmetry breast as well as smaller breast can be obtained.

Stromal vascular fraction(SVF)are the remaining cells after removing mature fat cells in the adipose tissue. Containing a certain amount of adipose derived stem cells(ADSCs), SVF also includes many other cells, which may have the potential of promoting angiogenesis. In this review, the role of SVF in angiogenesis after fat transplantation was summarized by intensive reading relative literature in recent years. The result is that angiogenesis and fat graft revascularization are regulated by various factors: SVF promotes secretion of a diverse array of cytokines and growth which are capable of stabilizing endothelium vascular network. ADSCs have the potential of differentiating into smooth muscle cells and endothelial cells which can coroperate to form new blood vessels.

Objective To synthesize 99Tcm-TP5-3 and evaluate its biodistribution and kinetics as a molecular probe for the detection of apoptosis,and evaluate tumor apoptosis after a single dose of paclitaxel chemotherapy in MDA-MB-231 breast tumor model.Methods TP5-3 was labeled with 99Tcm directly,and analyzed with HPLC.The radioactivity in tissues was measured and expressed as ％ID/g and T/NT (tumor/muscle).The mice bearing MDA-MB-231 breast tumor were divided into two groups:the treatment group which was given a single dose of paclitaxel (40 mg· kg-1,via tail vein),and the control group which was injected with the same volume of normal saline.After therapy,99Tcm-TP5-3 was injected via tail vein in both groups (100 μ1 for each mouse).MicroSPECT/CT was performed at 3 h postinjection.Radioactivity in different tissues was determined after imaging.Apoptotic cells were measured with flow cytometry.The morphological changes of the apoptotic cells were observed by light microscopies.One-way analysis of variance,two-sample t test and linear correlation analysis were used to analyze the data.Results The radiolabeling efficiency was ＞ 95％ and the radiochemical purity of 99Tcm-TP5-3 was (96.0± 1.5)％ at room temperature for 4 h.The predominant uptake was found in the kidneys at 30 min postinjection ((8.48± 1.07) ％ID/g),with rapid tracer clearance from the circulation.By comparison with activity at 5 min postinjection ((13.74± 4.21) ％ID/g),85％ of the initial activity reduced in blood at 4 h ((2.07±0.35) ％ID/g; F=11.310,P＜ 0.05).99Tcm-TP5-3 was mainly accumulated in the kidneys,liver and stomach,and excreted via the kidneys.T/NT in the treated group was 4.21±0.06,which was significantly higher than that of the control group (1.57±0.67; t =12.820,P＜0.05).The radioactivity of tumor tissue in the treatment group was much higher than that in the control group (4.82±0.54) ％ID/g vs (1.44±0.38) ％ID/g,t=0.679,P＜0.05).The tumor uptake of 99Tcm-TP5-3 in the treatment group positively correlated well with the apoptotic cells (r =0.985,P＜0.05).Histopathology further confirmed that a large number of apoptosis had occurred in the tumor after paclitaxel treatment.Conclusion 99Tcm-TP5-3 appears to have potential to be a useful molecular probe for imaging tumor cell apoptosis.

This study is to investigate the apoptotic induction effect of the combination of diosgenin and TNF-related apoptosis-inducing ligand (TRAIL) on non-small-cell lung cancer cell line A549 by using the Chou-Talalay method, and observe the mechanism of the combination. The apoptotic effect of diosgenin or TRAIL alone and their combination on A549 and normal cell line 293T proliferation was measured by MTT assay. Chou-Talalay method was used to evaluate the combination effect. Apoptosis was examined by Hoechst 33342 staining and flow cytometry assay. Western blotting detects the expression of apoptosis-associated proteins. Diosgenin or TRAIL alone can inhibit proliferation ofA549 in a concentration-dependent manner. According to the Chou-Talalay method, when f(a) = 0.1, CI > 1, when f(a) > 0.1, CI < 1. Combined with TRAIL, the IC50 of diosgenin decreases from 21.864 to 14.810 micromol x L(-1) (P < 0.05) on A549 cells. But for 293T cells, IC50 of diosgenin does not change significantly. As with Hoechst 33342 staining and flow cytometry assay, the apoptosis ratios also increased in the combination group. At protein expression level, combination-treated group displays increased Caspase-8, Caspase-9, Bid, Caspase-3 activation and PARP cleavage, significantly decreased Bcl-2 and increased Bax expression, and MAPK pathways were activated. The combination of diosgenin and TRAIL has synergistic effect on A549 cells.

Objective To investigate the Camtrylobacterjejuni's risk factors which were associated with the development of Guillain-Barre syndrome( GBS), the galE gene of C. jejuni strains were sequenced and the sequencing results were compared with other C. jejuni strains. Methods Selecting three GBS-asso-ciated C.jejuni strains isolated from stools of GBS patients who had been diagnosed as AMAN pattern by clin-ical and electrophysiological test from Hebei province, China. After sequencing galE gene, the results were spliced and assembled into a complete sequence by the terminals overlapped each other. The sequences of galE gene were compared with the corresponding sequences in GenBank to find the mutation and constructed the phylogenetic tree. Results The variation frequency of galE sequences of GBS-associated C. jejuni were higher than that of non-GBS-associated C. jejuni. The phylogenetic analysis demonstrated that each of the three C. jejuni strains was separately genetically closed to three strains which sequences have published in GenBank. The alignment with the related sequence of NCTC11168 shows that there are 4 same mutations in the galE gene of the three C. jejuni strains. The phylogenic tree reflected the regional feature of C. jejuni. Conclusion The probability of sequence variation of galE of GBS-associated C.jejuni is significantly higher than non-GBS-associated C. jejuni strains, the relation between the variation and GBS-pathogenesis remains to be further confirmed. The mutations found in the three C. jejuni strains established the foundation for ex-ploring the biologically characteristic of GBS-associated C. jejuni strains.
