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%.

OBJECTIVE:
This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province.
METHODS:
We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed.
RESULTS:
The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α 3.7/αα (50.23%) and β IVS-II-654/β N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively.
CONCLUSION
Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

BACKGROUND:
Ventricular remodeling after acute anterior wall ST-segment elevation myocardial infarction (AAMI) is an important factor in occurrence of heart failure which additionally results in poor prognosis. Therefore, the treatment of ventricular remodeling needs to be further optimized. Compound Danshen Dripping Pills (CDDP), a traditional Chinese medicine, exerts a protective effect on microcirculatory disturbance caused by ischemia-reperfusion injury and attenuates ventricular remodeling after myocardial infarction.
OBJECTIVE:
This study is designed to evaluate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function after AAMI on a larger scale.
METHODS:
This study is a multi-center, randomized, double-blind, placebo-controlled, parallel-group clinical trial. The total of 268 patients with AAMI after primary percutaneous coronary intervention (pPCI) will be randomly assigned 1:1 to the CDDP group (n=134) and control group (n=134) with a follow-up of 48 weeks. Both groups will be treated with standard therapy of ST-segment elevation myocardial infarction (STEMI), with the CDDP group administrating 20 tablets of CDDP before pPCI and 10 tablets 3 times daily after pPCI, and the control group treated with a placebo simultaneously. The primary endpoint is 48-week echocardiographic outcomes including left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume index (LVEDVI), and left ventricular end-systolic volume index (LVESVI). The secondary endpoint includes the change in N terminal pro-B-type natriuretic peptide (NT-proBNP) level, arrhythmias, and cardiovascular events (death, cardiac arrest, or cardiopulmonary resuscitation, rehospitalization due to heart failure or angina pectoris, deterioration of cardiac function, and stroke). Investigators and patients are both blinded to the allocated treatment.
DISCUSSION
This prospective study will investigate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function in patients undergoing pPCI for a first AAMI. Patients in the CDDP group will be compared with those in the control group. If certified to be effective, CDDP treatment in AAMI will probably be advised on a larger scale.

Applying Chinese medicine (CM) is an important strategy for malignant tumor treatment in China. One of the significant characteristics of CM is to treat diseases based on syndrome differentiation. For Western medicine, it is of important clinical significance to formulate guidelines for the diagnosis and treatment of cancer patients based on the characteristics of disease differentiation. In Chinese clinical practice, the combination of disease differentiation and syndrome differentiation is an important feature for cancer treatment in the past. Currently, molecular profiling and genomic analysis-based precision medicine optimizes the anticancer drug design and holds the greatest success in treating cancer patients. Therefore, we want to know which populations of cancer patients can benefit more from CM treatment if the theory of precision medicine is applied to CM clinical practice. So, we developed a novel diagnostic and therapeutic strategy "disease-syndrome differentiation-genomic profiling-prescriptions" for cancer patients by CM syndrome differentiation and precision medicine. As a result, this strategy has greatly enhanced the anti-tumor efficacy of CM and improved clinical outcomes for cancer patients with some gene mutations. Our idea will hopefully establish a novel approach for the inheritance and innovation of CM.

Objective To investigate the effectiveness and cost of 50% and 80% wettable powder of niclosamide ethanolamine salt (NESWP) and 26% metaldehyde and niclosamide suspension concentrate (MNSC) in hilly schistosomiasis-endemic regions, so as to provide insights into the selection of chemical molluscicides in hilly regions. Methods In September 2020, a wasteland in Guanshanqiao Village, Yanrui Township, Yushan County of Jiangxi Province was selected as the experimental region, which was sectioned into five blocks and defined as four experimental groups (A1, A2, B, C) and a blank control group (D). 80% NESWP were given at doses of 1 g/m2 and 1.5 g/m2 in groups A1 and A2 using the spraying method, 50% NESWP was given at a dose of 2 g/m2 in Group B using the spraying method, and 26% MNSC was at a dose of 4 g/m2 in Group C using the spraying method, while no chemical treatment was given in Group D. Snail survey was performed using a systematic sampling method before chemical treatment and 1, 3, 7 d and 15 d post-treatment to examine the molluscicidal effect, and all molluscicidal costs were estimated to calculate the cost of chemical treatment per 1 m2 and the cost of the reduction in the mean density of living snails per 1%. Results The highest mortality of snails was 78.95% and the lowest density of living snails was 0.2388 snails/0.1 m2 in the experimental groups within 7 d of chemical treatment, and the highest mortality of snails was 94.74% and the lowest density of living snails was 0.058 0 snails/0.1 m2 7 d post-treatment. There were no significant differences in the snail mortality among the A1, A2, B and C groups 1 (χ2 = 2.250, P > 0.05), 3 (χ2 = 1.779, P > 0.05) or 15 d post-treatment (χ2 = 2.286, P > 0.05), while a significant difference was detected in the snail mortality among the four groups 7 d post-treatment (χ2 = 7.990, P = 0.046). In addition, there were no significant differences in the snail mortality between A1 and A2 groups 1 (χ2 = 0.724, P > 0.05), 3 (χ2 = 0.584, P > 0.05), 7 (χ2 = 0.400, P > 0.05) or 15 d post-treatment (χ2 = 0.251, P > 0.05). The costs of chemical treatment per 1 m2 were 0.58, 0.60, 0.64 Yuan and 0.73 Yuan in groups A1, A2, B and C, and the costs of the mean density of living snail per 1% reduction were 19.29, 20.44, 21.68 Yuan and 23.53 Yuan in groups A1, A2, B and C, respectively. Conclusion 80% NESWP shows a high molluscicidal efficacy and low cost in hilly schistosomiasis-endemic regions.

BACKGROUND:
Albuvirtide is a once-weekly injectable human immunodeficiency virus (HIV)-1 fusion inhibitor. We present interim data for a phase 3 trial assessing the safety and efficacy of albuvirtide plus lopinavir-ritonavir in HIV-1-infected adults already treated with antiretroviral drugs.
METHODS:
We carried out a 48-week, randomized, controlled, open-label non-inferiority trial at 12 sites in China. Adults on the World Health Organization (WHO)-recommended first-line treatment for >6 months with a plasma viral load >1000 copies/mL were enrolled and randomly assigned (1:1) to receive albuvirtide (once weekly) plus ritonavir-boosted lopinavir (ABT group) or the WHO-recommended second-line treatment (NRTI group). The primary endpoint was the proportion of patients with a plasma viral load below 50 copies/mL at 48 weeks. Non-inferiority was prespecified with a margin of 12%.
RESULTS:
At the time of analysis, week 24 data were available for 83 and 92 patients, and week 48 data were available for 46 and 50 patients in the albuvirtide and NRTI groups, respectively. At 48 weeks, 80.4% of patients in the ABT group and 66.0% of those in the NRTI group had HIV-1 RNA levels below 50 copies/mL, meeting the criteria for non-inferiority. For the per-protocol population, the superiority of albuvirtide over NRTI was demonstrated. The frequency of grade 3 to 4 adverse events was similar in the two groups; the most common adverse events were diarrhea, upper respiratory tract infections, and grade 3 to 4 increases in triglyceride concentration. Renal function was significantly more impaired at 12 weeks in the patients of the NRTI group who received tenofovir disoproxil fumarate than in those of the ABT group.
CONCLUSIONS:
The TALENT study is the first phase 3 trial of an injectable long-acting HIV drug. This interim analysis indicates that once-weekly albuvirtide in combination with ritonavir-boosted lopinavir is well tolerated and non-inferior to the WHO-recommended second-line regimen in patients with first-line treatment failure.

Objective: To evaluate the long-term outcome of patients with hypertrophic obstructive cardiomyopathy(HOCM) after percutaneous transluminal septal ablation(PTSMA). Methods: HOCM patients who underwent PTSMA and surgical myectomy at the Chest Hospital of Shanghai Jiao Tong University from April 2001 to February 2019 were included in this retrospective analysis. Patients were divided into PTSMA group and surgical myectomy group. In addition, patients undergoing PTSMA were further divided into HOCM-PTSMA non-survivor group and HOCM-PTSMA survivor group. The general clinical information, procedural/surgical information and complications during hospitalization were compared between groups. Multivariate Cox regression model was used to analyze the independent risk factors for all-cause death in HOCM patients after PTSMA. Results: A total of 104 patients with HOCM who underwent PTSMA were enrolled. Mean age of the patients was (54±15) years old, including 41 females (38.7%). The follow-up time was 37.5(14.3, 76.8) months. At the last follow-up, 12 patients died (HOCM-PTSMA non-survivor group) and 92 were alive(HOCM-PTSMA survivor group). The proportion of patients with NYHA function class Ⅲ/Ⅳ was higher(P=0.036), and the posterior wall of the left ventricle was thicker(P=0.006) in the HOCM-PTSMA non-survivor group than in the HOCM-PTSMA survivor group. The immediate success rate of PTSMA in this cohort was 66%(70/104). The amount of absolute alcohol during the operation in the HOCM-PTSMA non-survivor group was (2.9±0.8) ml, which tended to be higher as compared to that in the HOCM-PTSMA survivor group((2.4±1.0)ml, P=0.056). Kaplan-Meier survival curve analysis showed that patients with HOCM who underwent PTSMA had an all-cause mortality-free survival rate of 90.1%, 78.3%, and 56.9% at 5, 10 and 15 years, and a HOCM-free survival rate of 91.3%, 79.4% and 57.7% at 5, 10 and 15 years, respectively. Multivariate Cox regression analysis showed that age≥ 65 years was an independent risk factor for all-cause death after PTSMA in patients with HOCM (HR=2.697, 95%CI 1.292-18.977, P=0.020). There were 32 patients in the surgical myectomy group. The proportion of patients with NYHA function class Ⅲ/Ⅳ was higher than that in the PTSMA group(P<0.001), while age, gender, and major comorbidities(atrial fibrillation, coronary heart disease, hypertension, and diabetes) as well as the left atrium dimension were all similar between the two groups(all P>0.05). Patients in the surgical myectomy group were followed up for 38.0(17.6, 64.2)months, and no deaths occurred during the follow-up period. Kaplan-Meier survival curve analysis showed that there were no statistically significant differences in all-cause-free and HOCM-free survival rates between patients in PTSMA group and surgical myectomy group(P=0.089 and 0.110, respectively). Conclusion: PTSMA is safe and effective for the treatment of patients with HOCM, and the long-term survival rate of patients after PTSMA is similar as patients undergoing classical surgical myectomy surgery.
