Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R2 of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

Artemisia stolonifera is a relative of A. argyi. The two species are difficult to be distinguished due to the similarity in leaf shape and have even less distinctive features after processing. This study aims to establish a method to quickly distinguish between them. At the same time, we examined the reasonability and applicability of the specific polymerase chain reaction(PCR) method. The C/T single nucleotide polymorphism was detected at the position 202 of the sequence, based on which specific primers were designed to identify these two species. The PCR with the specific primer JNC-F and the universal primer ITS3R produced a specific band at 218 bp for A. argyi and no band for A. stolonifera, which can be used to detect at least 3% of A. argyi samples mixed in A. stolonifera samples. The PCR with the specific primer KY-F and the universal primer ITS3R produced a specific band at 218 bp for A. stolonifera and no band for A. argyi, which can be used to detect at least 5% of A. stolonifera samples mixed with A. argyi. The limit of detection of the established method was 5 ng DNA. The established PCR method can accurately distinguish between A. stolonifera and A. argyi, which provides an experimental basis for the quality control of A. stolonifera and determines whether the herbs are adulterated.

BACKGROUND:
Some porous materials have been developed to enhance biologic fusion of the implants to bone in spine fusion surgeries. However, there are several inherent limitations. In this study, a novel biomedical porous tantalum was applied to in vitro and in vivo experiments to test its biocompatibility and osteocompatibility.
METHODS:
Bone marrow-derived mesenchymal stem cells (BMSCs) were cultured on porous tantalum implant. Scanning electron microscope (SEM) and Cell Counting Kit-8 assay were used to evaluate the cell toxicity and biocompatibility. Twenty-four rabbits were performed discectomy only (control group), discectomy with autologous bone implanted (autograft group), and discectomy with porous tantalum implanted (tantalum group) at 3 levels: L3-L4, L4-L5, and L5-L6 in random order. All the 24 rabbits were randomly sacrificed at the different post-operative times (2, 4, 6, and 12 months; n = 6 at each time point). Histologic examination and micro-computed tomography scans were done to evaluate the fusion process. Comparison of fusion index scores between groups was analyzed using one-way analysis of variance. Other comparisons of numerical variables between groups were made by Student t test.
RESULTS:
All rabbits survived and recovered without any symptoms of nerve injury. Radiographic fusion index scores at 12 months post-operatively between autograft and tantalum groups showed no significant difference (2.89 ± 0.32 vs. 2.83 ± 0.38, F = 244.60, P = 0.709). Cell Counting Kit-8 assay showed no significant difference of absorbance values between the leaching liquor group and control group (1.25 ± 0.06 vs. 1.23 ± 0.04, t = -0.644, P = 0.545), which indicated the BMSC proliferation without toxicity. SEM images showed that these cells had irregular shapes with long spindles adhered to the surface of tantalum implant. No implant degradation, wear debris, or osteolysis was observed. Histologic results showed solid fusion in the porous tantalum and autologous bone implanted intervertebral spaces.
CONCLUSION
This novel porous tantalum implant showed a good biocompatibility and osteocompatibility, which could be a valid biomaterial for interbody fusion cages.

In this study, the inhibitory effect of human umbilical cord-derived mesenchymal stem cells (hUCMSC) on interleukin-17 (IL-17) production in peripheral blood T cells from patients with spondyloarthritis (SpA) were investigated, in order to explore the therapeutic potential of hUCMSC in the SpA. Peripheral blood mononuclear cells (PBMNC) were isolated from patients with SpA (n = 12) and healthy subjects (n = 6). PBMNC were cultured in vitro with hUCMSC or alone. The expression of IL-17 in CD4(+) T cells or γ/δ T cells were determined in each subject group by flow cytometry. IL-17 concentrations in PBMNC culture supernatants were measured by ELISA. The results indicated that the proportion of IL-17-producing CD4(+) T cells and IL-17-producing γ/δ T cells of SpA patients were 4.5 folds and 5 folds of healthy controls [CD3(+)CD4(+)IL-17(+) cells (3.42 ± 0.82)% vs (0.75 ± 0.25)%, P < 0.01; CD3(+)γδTCR(+)IL-17(+) cells (0.30 ± 0.10)% vs (0.06 ± 0.02)%, P < 0.01]. After co-culture of PBMNC in patients with hUCMSC, the increased proportions of CD3(+)CD4(+)IL-17(+) cells and CD3(+)γδTCR(+)IL-17(+) cells in SpA patients were inhibited significantly by hUCMSC [CD3(+)CD4(+)IL-17(+) cells (3.42 ± 0.82)% vs (1.81 ± 0.59)% (P < 0.01); CD3(+)γδTCR(+)IL-17(+) cells (0.30 ± 0.10)% vs (0.16 ± 0.06)% (P < 0.01]. In response to phytohemagglutinin (PHA, 1 µg/ml), PBMNC from SpA patients secreted more IL-17 than that from healthy control [(573.95 ± 171.68) pg/ml vs (115.53 ± 40.41) pg/ml (P < 0.01)]. In the presence of hUCMSC, PBMNC of SpA patients produced less amount of IL-17 [(573.95 ± 171.68) pg/ml vs (443.20 ± 147.94) pg/ml, (P < 0.01)]. It is concluded that the IL-17 production in peripheral blood T cells from SpA patients can be inhibited by hUCMSC, which have therapeutic potential for SpA.

This paper explored the curative effect of combined modality therapy and extended field radiotherapy for early-stage Hodgkin's Lymphoma. 104 cases of early-stage Hodgkin's Lymphoma from Jan 1987 to Dec 2010 in PLA Hospital 307 were retrospectively analyzed, including 76 cases in combined modality therapy group and 28 cases in extended field radiotherapy group, and the long-term efficacy and toxicity of two therapy modalities were evaluated. The results showed that the median survival time of 104 cases was 85.42 months, the complete remission rates of combined modality therapy and extended field radiotherapy groups were 72.4 and 71.4 respectively (P = 0.924); the overall response rates of combined modality therapy and extended field radiotherapy groups were 97.4 and 96.4 respectively (P = 0.779); the 5-year overall survival (OS) rates in the 2 groups were 89.5 and 89.1 respectively, and the 8-year OS rates of the 2 groups were 81.3 and 70.6. No statistical difference was found in above-mentioned 2 groups. Moreover, the 5-year progression free survival (PFS) rates of these 2 groups were 84.2 and 69.0 (P = 0.04), and 8-year PFS rates of these 2 groups were 80.0 and 55.5 (P = 0.04) respectively, the 5-year relapse rates of these 2 groups were 28.1 and 45.6 (P = 0.023) respectively. It is concluded that the combined modality therapy can raise the PFS rate and reduce the relapse rate as compared with extended field radiotherapy for early-stage Hodgkin's Lymphoma, but there is no difference in the overall survival rate between the 2 groups.

OBJECTIVETo evaluate the effect of CYP11B2 gene -344T/C polymorphism on renin-angiotensin-aldosterone system (RAAS) activity and blood pressure in response to hydrochlorothiazide (HCTZ) treatment in Han Chinese patients with essential hypertension.
METHODSEight hundred and twenty-nine patients with mild/moderate essential hypertensive were enrolled. All subjects had their antihypertensive medications withdrawn. After two weeks of wash-out period with placebo, each patient was given 12.5 mg of HCTZ per day for the next six weeks. Physical, biochemical measurements, and the activity of RAAS were taken at the end of the wash-out period (baseline) and 6-week diuretic therapy period. Changes in systolic and diastolic blood pressure were analyzed for association with interaction between genotypes at CYP11B2 -344T/C polymorphism and gender.
RESULTSA total of 776 patients completed the study. 17.5% of subjects have achieved blood pressure normalization after six weeks treatment. For male patients, the aldosterone level with CC genotype was significantly higher than that of those with TT or TC genotype. Following the HCTZ treatment, the blood pressure response in patients with CC genotype was less obvious than that in others, whilst the increase of aldosterone level was greater. For female patients, no association was found between CYP11B2 -344T/C polymorphism and aldosterone level. Following the HCTZ treatment, the blood pressure response in patients with CC genotype was greater than others, whilst the increase of aldosterone activity was less apparent.
CONCLUSIONIn males, the -344T/C polymorphism of CYP11B2 gene is associated with aldosterone level, and the change of aldosterone level was greater, the blood pressure response was weaker after HCTZ treatment. In females, there was no association between this polymorphism and aldosterone level. The change of aldosterone level and blood pressure response to HCTZ were different from that in males.
