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:Cardiopulmonary resuscitation quality index (CQI) is based on pulse oximetry plethysmographic waveform (POP), which have been proved able to reflect the peripheral circulation state as good as the quality of chest compression during cardiopulmonary resuscitation (CPR). It has been confirmed that CQI is as good as the partial pressure of end-tidal carbon dioxide (P ETCO 2) in prognostic evaluation of CPR patients. The purpose of this study was to explore whether advanced airway establishment affects the prognostic value of CQI during CPR. Methods:This was a prospective descriptive study. 376 patients receiving CPR were divided into advanced airway group and non-advanced airway group according to whether advanced airway was established, each of which was divided into ROSC (return of spontaneous circulation) group and non-ROSC group according to whether they got ROSC. The changes of CQI and P ETCO 2 during CPR were collected, and the relation of these parameters and the prognosis of patients was analyzed. Results:In advanced airway group, both CQI [(63.3±20.7) vs (49.7±23.8)] and P ETCO 2 [(19.8 (11.4, 31.6) vs 8.8 (3.3, 15.8)] mmHg were statistically different between ROSC group and non-ROSC group ( P <0.05). The cut-off value for these two parameters were 60.4 and 16.3 mmHg respectively. There was no significant difference between the two curves ( P>0.05). In the non-advanced airway group, CQI [(63.0±21.8) vs (42.2±29.0)] were also statistically different between the ROSC group and the non-ROSC group ( P <0.05). The cut-off value of CQI in advanced airway group and non-advanced airway group were 60.4 and 61.1, respectively. And there was no statistical difference between the two curves ( P>0.05). Conclusions:During CPR, CQI can be used to evaluate the prognosis of patients, which is as good as that of P ETCO 2. Establishment of advanced airway does not affect the prognostic evaluation of CQI during CPR.

Objective To characterize a species of the genus Tricula and parasitized trematodes in schistosomiasis-endemic areas of Yunnan Province using a molecular analysis, so as to understand their taxonomic positions. Methods Tricula spp. and Oncomelania snails were collected from Xiangyun County, Yunnan Province, and cercaria parasitizing snails were observed using crushing followed by microscopy. Cercaria parasitizing Tricula snails at various morphologies were sampled using a shedding method. Genomic DNA was extracted from snail soft tissues and cercariae, and the 16S rRNA, COI, 28S rDNA genes in snails and the ND1 and 28S rDNA genes in cercariae were amplified using a PCR assay and sequenced. The species of Tricula snails and their parasitized trematodes was characterized using sequence alignment and phylogenetic analysis. Results Among 382 Tricula snails detected, there were three types of trematode cercariae found, including the non-forked (20.94%, 80/382), double-forked (3.40%, 13/382) and swallow shapes (7.07%, 27/382). Sequence and phylogenetic analyses showed that the 16S rRNA, COI and 28S rDNA gene sequences of this species of Tricula had high homology to those in Delavaya dianchiensis, and were clustered in a branch. Sequencing analysis of the ND1 and 28S rDNA genes revealed that the non-forked cercariae belonged to the family Pleu- rogenidae, the swallow-shaped cercariae belonged to the family Opecoelidae, and the double-forked cercariae belonged to another species of the genus Schistosoma that was different from S. sinensium and S. ovuncatum. Conclusion The species and taxonomy of Triculla spp. and their parasitized trematodes are preliminarily determined in schistosomiasis-endemic areas of Yunnan Province; however, further studies are required to investigate the more definite taxonomy and pathogenicity.

Objective To assess the effectiveness of infectious source control at various stages of transmission control of schistosomiasis in Eryuan County of Yunnan Province, so as to provide insights into the further monitoring and management of infectious sources of schistosomiasis. Methods Wenbi Village, a plateau subtype region and Qiandian Village, a mountain subtype region in Eryuan County were selected as the study areas. The species, schistosome infection and transmission capability of infectious sources were investigated in Wenbi and Qiandian villages in 2011 and 2018 and were compared. Results Schistosome infections were detected in human, bovine, horse, dog and mouse in Qiandian Village in 2011, with positive rates of 1.19%, 0.91%, 1.25%, 3.13% and 0.95%, respectively, and human, bovine and dog were found to have schistosome infections, with positive rates of 0.76%, 1.66% and 9.30%, respectively. However, no infections were identified in human, bovine, horse, pig, dog, sheep or mouse in these two villages in 2018. A total of 731 wild feces were collected in both villages in 2011. In Qiandian Village, horse, bovine and dog feces accounted for 34.40%, 29.80% and 20.20% of all fecal samples, and dog and horse feces were found to have schistosome infections (11.94% and 6.90% positive rates, respectively). In Wenbi Village, dog, bovine and human feces accounted for 44.59%, 39.83% and 14.29% of all fecal samples, and dog, human and bovine feces were found to have schistosome infections (16.95%, 9.52% and 2.33% positive rates, respectively). In 2018, a total of 204 wild feces were collected in both villages, and no schistosome infections were identified. Sheep, dog and bovine feces accounted for 36.27%, 33.33% and 27.45% of all fecal samples in Qiandian Village, and dog, bovine and human feces accounted for 72.55%, 11.76% and 10.78% of all fecal samples in Wenbi Village. Conclusions A remarkable achievement has been obtained in the control of infectious sources of schistosomiasis in Eryuan County, and the role of human and bovine as the major infectious sources of schistosomiasis has been effectively controlled. In the future, the integrated strategy with emphasis on the control of infectious sources should be intensified, and the management of reservoir hosts including dog and mouse should be strengthened.

Objectives: Modified extended Morrow procedure for treatment of children with hypertrophic obstructive cardiomyopathy (HOCM) is a complicated and challenging procedure. Our study sought to assess the effect and outcome of modified extended Morrow procedure in children with HOCM. Methods: From January 2010 to July 2017, 50 consecutive pediatric (age≤14 years) patients with HOCM underwent transaortic modified extended Morrow procedure in Fuwai Hospital. Clinical data of these patients were analyzed retrospectively. Pre-operative and post-operative echocardiography data were analyzed, including left atrial size, left ventricular end diastolic diameter, left ventricular ejection fraction, left ventricular outflow tract peak pressure, ventricular septal thickness, mitral systolic anterior motion and grade of mitral regurgitation. Results: Mean age at the time of operation was (84.4±57.7) month (6 month -14 year). Mean body weight at the time of surgery was (28.4±20.7) kg (4.3-92.0) kg. There were 2 deaths after the operation. Three patients had postoperative complete heart block and received permanent pacemaker implantation. After myectomy, left ventricular outflow tract gradient decreased from (74.8±25.0) mmHg to (19.6±17.3) mmHg (P<0.001); the postoperative thickness of ventricular septum decreased from (21.2±9.7) mm to (14.3±6.7) mm (P<0.001); mitral regurgitation degree reduced from 2.2±1.0 to 0.67±0.72, P<0.001). Concomitant surgical procedures were required in 22 patients (44.0%). There was no late death during a follow-up of (27.7±14.0) months. Patients' symptoms were significantly improved post operation and all surviving patients were in New York Heart Association functional class I or II during follow-up. Conclusions: Modified extended Morrow procedure is safe and effective in children with HOCM, post-procedural clinical outcome is excellent, and this procedure can significantly improve the quality of 1ife and the long-term prognosis in these patients.

Objective To investigate the effect of cysteine protease inhibitor derived from S chistosoma japonicum(SjCys-tatin)on dextran sodium sulfate(DSS)-induced acute ulcerative colitis in mice.Methods Eighteen C57BL/6 mice were ran-domly divided into three groups:a control group treated with PBS(Group A),a DSS-induced-colitis group treated with PBS(Group B),and a DSS-induced-colitis group treated with SjCystatin(Group C).Colitis was induced in mice by giving 3％DSS orally for 7 days.During this period,the mice were daily injected with 10μg of SjCystatin or PBS only as a control intraperitone-ally.The mice were monitored daily for their clinical manifestations and given scores based on disease activity index(DAI).The severity of colonic inflammation was monitored by the macroscopic score and pathological change.The cytokine profile including TNF-α,IL-4,IL-6 and IL-10 in the supernatants of colon homogenate was detected by ELISA.Results Compared with Group A(0.50 ± 0.28),the DAI score increased significantly in Group B(9.30 ± 1.30)(F=86.86,P<0.01),with remarkable path-ological damages seen in colon tissues.and the levels of TNF-α and IL-6 were(321.33±67.01)and(403.58 ±180.51)pg/mL.The DAI score significantly reduced in Group C(6.67±1.57)as compared to Group B(F=86.86,P<0.01),with improve-ments in the macroscopic and microscopic pathology in mouse colon specimens.As compared to Group B,the levels of TNF-α [(188.14 ± 40.14)pg/mL] and IL-6 [(209.71 ± 48.47)pg/mL] significantly decreased(F=17.46 and 9.89,both P<0.01).Con-clusion SjCystatin has a significantly inhibitory effect for alleviating DSS-induced acute ulcerative colitis in C57BL/6 mice.

Objective: To study the safety and efficacy of Bushen Daozhuo Granules (BDG) in the treatment of type Ⅲ prostatitis. METHODS: This multicenter randomized controlled clinical trial included 478 patients with type Ⅲ prostatitis, 290 in the trial group and 188 as controls, the former treated with BDG at 200 ml bid and the latter with tamsulosin hydrochloride sustainedrelease capsules at 0.2 mg qd, both for 4 weeks. Before treatment, after 4 weeks of medication, and at 4 weeks after drug withdrawal, we obtained the NIH Chronic Prostatitis Symptom Index (NIHCPSI) scores and compared the safety and effectiveness rate between the two groups of patients. RESULTS: Compared with the baseline, the NIHCPSI score was markedly decreased in the control group after 4 weeks of medication (21.42 ± 4.02 vs 15.67 ± 3.65, P < 0.05) but showed no statistically significant difference from that at 4 weeks after drug withdrawal (19.03 ± 3.86) (P>0.05), while the NIHCPSI score in the trial group was remarkably lower than the baseline both after 4 weeks of medication and at 4 weeks after drug withdrawal (10.92 ± 2.06 and 12.91 ± 2.64 vs 21.58 ± 3.67, P < 0.05). The trial group exhibited both a higher rate of total effectiveness and safety than the control (P < 0.05). CONCLUSIONS BDG is safe and effective for the treatment of type Ⅲ prostatitis.

Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.
