Objective:To investigate genetic variation profiles of δ-globin (HBD gene) and hematological phenotypes in Guangdong population.Methods:Retrospective case analysis was performed in this study. Blood samples of 11 616 couples who participated in free thalassemia screening in Guangzhou from July 2020 to December 2022 were collected which underwent blood routine tests and hemoglobin (Hb) capillary electrophoresis. According to the results, 154 samples were enrolled in this study: (1)group of 35 cases with HbA 2 <2.0% but no HbF band; (2)group of 64 cases with HbA 2 < 2.0% and HbF band; (3)group of 25 cases with HbA 2 <2.0% and suspected HbA 2 variants; (4) group of 25 cases with HbA 2 ≥2.0% and <3.5% and HbF band, as well as abnormal blood routine report [mean corpuscular volume (MCV) <82 fl and/or mean corpuscular hemoglobin (MCH) <27 pg]; (5)group of 5 cases with HbA 2 ≥2.0% and <3.0% accompanied with β thalassemia gene carriers Sanger sequencing was used to detect single nucleotide variants of δ-globin. Results:(1) A total of 22 genetic variations were detected, including 6 de novo variations, and the top 3 genetic variations were respectively c.-127T>C (57.02%, 65/114), c.-80T>C (9.65%, 11/114), c.349C>T (7.89%, 9/114). (2) In group of patients with HbA 2 <2.0% but no HbF band, 22 cases (62.85%, 22/35) had HBD gene variation, including 7 cases with MCV and MCH lower than reference values, 4 cases with α thalassemia; 13 cases had no HBD gene variation, including 12 cases with lower MCV and MCH. Among 19 cases with abnormal blood routine test results, levels of HbA 2 in patients (7 cases) with HBD gene variation were lower compared with those without HBD gene variation (12 cases) ( P<0.01%). (3)In group of patients with HbA 2<2.0% with HbF band, 59 cases (92.18%, 59/64) had HBD gene variations whose mutations all occurred in promoter region, and the HbF were all lower than 5.0%; 5 cases with HbF >5.0% had no HBD gene variation. (4) In group of patients with HbA 2 <2.0% and suspected HbA 2 variants, the detection rate was 100% (25/25) and δ-globin variants <1.0%. (5) In group of patients with HbA 2 ≥2.0% and <3.5% and HbF band accompanied with abnormal blood routine results, no HBD gene variation was found. (6) In group of 5 patients with HbA 2 ≥2.0% and <3.0% with β thalassemia gene carriers, HBD gene variation were found in all cases, and the level of HbA 2 was (2.62±0.17)% and HbF was (3.62±2.22)%. Conclusions:There are various genotypes of HBD gene variation, among which HBD: c.-127T>C is the most common in Guangdong population in China. Mutations in the promoter region may cause decrease in HbA 2 and increase in HbF which is mostly less than 5% but exceeds 5.0% when combined with β thalassemia. Our study enriched the gene mutation profiles of HBD gene in Guangdong population.

Research progress and maturity assessment of continuous manufacturing of traditional Chinese medicine / 中国中药杂志

The pharmaceutical manufacturing model is gradually changing from intermittent manufacturing to continuous manufacturing and intelligent manufacturing. This paper briefly reviewed the supervision and research progress in continuous pharmaceutical manufacturing in China and abroad and described the definition and advantages of continuous pharmaceutical manufacturing. The continuous manufacturing of traditional Chinese medicine(TCM) at the current stage was summarized in the following three terms: the enhancement of the continuity of intermittent manufacturing operations, the integration of continuous equipment to improve physical continuity between units, and the application of advanced process control strategies to improve process continuity. To achieve continuous manufacturing of TCM, the corresponding key technologies, such as material property characterization, process modeling and simulation, process analysis technology, and system integration, were analyzed from the process and equipment, respectively. It was proposed that the continuous manufacturing equipment system should have the characteristics of high speed, high response, and high reliability, "three high(H~3)" for short. Considering the characteristics and current situation of TCM manufacturing, based on the two dimensions of product quality control and production efficiency, a maturity assessment model for continuous manufacturing of TCM, consisting of operation continuity, equipment continuity, process continuity, and quality control continuity, was proposed to provide references for the application of continuous manufacturing technology for TCM. The implementation of continuous manufacturing or the application of key continuous manufacturing technologies in TCM can help to systematically integrate advanced pharmaceutical technology elements and promote the uniformity of TCM quality and the improvement of production efficiency.

Manufacturing classification system for oral solid dosage forms of traditional Chinese medicines (Ⅱ): classification of tablets disintegration behavior / 中国中药杂志

In this paper, 50 batches of representative traditional Chinese medicine tablets were selected and the disintegration time was examined with the method in Chinese Pharmacopoeia. The disintegration time and disintegration phenomenon were recorded, and the dissolution behaviors of water-soluble and ultraviolet-absorbent components during the disintegration process of tablets were characterized by self-control method. The results revealed that coating type and raw material type influenced the disintegration time of tablets. It was found that only 4% of traditional Chinese medicine tablets had obvious fragmentation during the disintegration process, while 96% of traditional Chinese medicine tablets showed gradual dissolution or dispersion. Furthermore, according to the disintegration speed, disintegration phenomenon, and whether the cumulative dissolution of measured components was > 90% at complete disintegration, a disintegration behavior classification system(DBCS) was created for the regular-release traditional Chinese medicine tablets. As a result, the disintegration behaviors of 50 batches of traditional Chinese medicine tablets were classified into four categories, i.e. ⅠA_2, ⅠB_1, ⅡB_1, and ⅡB_2. traditional Chinese medicine tablets(Class I) with disintegration time ≤ 30 min were defined to be rapid in disintegration, which can be the objective of optimization or improvement of Chinese herbal extract(semi extract) tablets. Different drug release models were used to fit the dissolution curve of traditional Chinese medicine tablets with gradual dissolution or dispersion phenomenon(i.e. Type B tablets). The results showed that the dissolution curves of water-soluble components in the disintegration process conformed to the zero order kinetics and the Ritger-Peppas model. It could be inferred that the disintegration mechanisms of type B tablets were a combination of dissolution controlled and swelling controlled mechanisms. This study contributes to understanding the disintegration behavior of traditional Chinese medicine tablets, and provides a reference for the design and improvement of disintegration performance of traditional Chinese medicine tablets.

Patent application of intelligent quality control technology in traditional Chinese medicine production process: a review / 中国中药杂志

In the new stage for intelligent manufacturing of traditional Chinese medicine(TCM) from pilot demonstration to in-depth application and comprehensive promotion, how to raise the degree of intelligence for the process quality control system has become the bottleneck of the development of TCM production process control technology. This article has sorted out 226 TCM intelligent manufacturing projects that have been approved by the national and provincial governments since the implementation of the "Made in China 2025" plan and 145 related pharmaceutical enterprises. Then, the patents applied by these pharmaceutical enterprises were thoroughly retrieved, and 135 patents in terms of intelligent quality control technology in the production process were found. The technical details about intelligent quality control at both the unit levels such as cultivation, processing of crude herbs, preparation pretreatment, pharmaceutical preparations, and the production workshop level were reviewed from three aspects, i.e., intelligent quality sensing, intelligent process cognition, and intelligent process control. The results showed that intelligent quality control technologies have been preliminarily applied to the whole process of TCM production. The intelligence control of the extraction and concentration processes and the intelligent sensing of critical quality attributes are currently the focus of pharmaceutical enterprises. However, there is a lack of process cognitive patent technology for the TCM manufacturing process, which fails to meet the requirements of closed-loop integration of intelligent sensing and intelligent control technologies. It is suggested that in the future, with the help of artificial intelligence and machine learning methods, the process cognitive bottleneck of TCM production can be overcome, and the holistic quality formation mechanisms of TCM products can be elucidated. Moreover, key technologies for system integration and intelligent equipment are expected to be innovated and accelerated to enhance the quality uniformity and manufacturing reliability of TCM.

The emerging role of blood lipoprotein levels in osteoporosis of postmenopausal women with rheumatoid arthritis / 中华风湿病学杂志

Objective:To retrospectively analyze the correlation between blood lipoprotein levels and the risk of osteoporosis (OP) development in postmenopausal patients with RA and its influencing factors.Methods:Patients hospitalized with a definite diagnosis of RA from July 2017 to May 2020 were retrospectively collected and analyzed by bone mineral density (BMD) in subgroups, using correlation analysis, di-chotomous Logistic regression to quantify independent associations between laboratory test results and out-comes, and restrictive cubic spline (RCS) to fit the relationship of OP risk occurrence.Results:Six hundred and sixty-six eligible RA patients were included according to inclusion criteria, including 253 RA-OP and 413 RA-non-OP patients. After exclusion of relevant influencing factors by comparing demographic characteristics, a significant correlation was found between blood HDL-C ( r=-0.11, P=0.006) LDL-C ( r=0.12, P=0.003) levels and RA-OP( P<0.05), and dichotomous Logistic regression showed that as BMI ( OR(95% CI)=0.81(0.77, 0.86), P<0.001], calcium [ OR(95% CI)=0.24(0.10, 0.63), P<0.001], HDL-C[ OR(95% CI)=0.38(0.22, 0.66), P<0.001] increased, the risk of developing OP in RA patients decreased. In contrast, the risk of developing OP increased with increasing age [ OR(95% CI)=1.10(1.07, 1.21), P<0.001), disease duration [ OR(95% CI)=1.00(1.00, 1.00), P=0.020], and LDL-C[ OR(95% CI)=1.71(1.38, 2.12), P<0.001]. Conclusion:Blood HDL-C and LDL-C levels are significantly correlated with the development of RA-OP, and can be used as predictors of OP development and good indicators for disease monitoring in RA patients.

Discordance analysis for apolipoprotein and lipid measures for predicting myocardial infarction in statin-treated patients with coronary artery disease: a cohort study / 老年心脏病学杂志（英文版）

BACKGROUND@#The optimal apolipoprotein or lipid measures for identifying statin-treated patients with coronary artery disease (CAD) at residual cardiovascular risk remain controversial. This study aimed to compare the predictive powers of apolipoprotein B (apoB), non-high-density lipoprotein cholesterol (non-HDL-C), low-density lipoprotein cholesterol (LDL-C), apoB/apolipoprotein A-1 (apoA-1) and non-HDL-C/HDL-C for myocardial infarction (MI) in CAD patients treated with statins in the setting of secondary prevention.@*METHODS@#The study included 9191 statin-treated CAD patients with a five-year median follow-up. All measures were analyzed as continuous variables and concordance/discordance groups by medians. The hazard ratio (HR) with 95% CI was estimated by Cox proportional hazards regression. Patients were classified by the clinical presentation of CAD for further analysis.@*RESULTS@#The high-apoB-low-LDL-C and the high-non-HDL-C-low-LDL-C categories yielded HR of 1.40 (95% CI: 1.04-1.88) and 1.51 (95% CI: 1.07-2.13) for MI, respectively, whereas discordant high LDL-C with low apoB or non-HDL-C was not associated with the risk of MI. No association of MI with discordant apoB versus non-HDL-C, apoB/apoA-1 versus apoB, non-HDL-C/HDL-C versus non-HDL-C, or apoB/apoA-1 versus non-HDL-C/HDL-C was observed. Similar patterns were found in patients with acute coronary syndrome. In contrast, no association was observed between any concordance/discordance category and the risk of MI in patients with chronic coronary syndrome.@*CONCLUSIONS@#ApoB and non-HDL-C better predict MI in statin-treated CAD patients than LDL-C, especially in patients with acute coronary syndrome. ApoB/apoA-1 and non-HDL-C/HDL-C show no superiority to apoB and non-HDL-C for predicting MI.

Discrete element simulation study of mixing process of Guizhi Fuling Capsules: parameter calibration / 中国中药杂志

The mixing process is a critical link in the formation of oral solid preparations of traditional Chinese medicine. This paper took the extract powder of Guizhi Fuling Capsules and Paeonol powder as research objects. The angle of repose, loose packing density, and particle size of the two powders were measured to calibrate discrete element simulation parameters for the mixing process. The discrete element method was used to calibrate the simulated solid density of Paeonol powder and extract powder of Guizhi Fuling Capsules based on the Hertz-Mindlin with JKR V2 contact model and particle scaling. The Plackett-Burman experimental design was used to screen out the critical contact parameters that had a significant effect on the simulation of the angle of repose. The regression model between the critical contact parameters and the simulated angle of repose was established by the Box-Behnken experimental design, and the critical contact parameters of each powder were optimized based on the regression model. The best combination of critical contact parameters of the extract powder of Guizhi Fuling Capsules was found to be 0.51 for particle-particle static friction coefficient, 0.31 for particle-particle rolling friction coefficient, and 0.64 for particle-stainless steel static friction coefficient. For Paeonol powder, the best combination of critical contact parameters was 0.4 for particle-particle static friction coefficient and 0.19 for particle-particle rolling friction coefficient. The best combination of contact parameters between Paeonol powder and extract powder of Guizhi Fuling Capsules was 0.27 for collision recovery coefficient, 0.49 for static friction coefficient, and 0.38 for rolling friction coefficient. The verification results show that the relative error between the simulated value and the measured value of the angle of repose of the two single powders is less than 1%, while the relative error between the simulated value and the measured value of the angle of repose of the mixed powder with a mass ratio of 1∶1 is less than 4%. These research results provide reliable physical property simulation data for the mixed simulation experiment of extract powder of Guizhi Fuling Capsules and Paeonol powder.

Objective:To investigate the intervention effects and influencing factors of family management intervention on parents' disease management ability, family function of children with coronary artery lesions in Kawasaki disease.Methods:This was a quasi experimental study. Conveniently, 88 parents of children with Kawasaki disease coronary artery lesions from the Children's Hospital of Chongqing Medical University from March 2020 to June 2021 were selected for the study, and they were divided into the control group and the intervention group according to the order of the first consultation with 44 cases in each group. In the control group, conventional care and health education were used, while in the intervention group, a 6-month family management intervention was implemented on the basis of the control group. Family Management Measure (FaMM), Family Assessment Device (FAD) were used to assess the parents' disease management ability, family function before and after the intervention, respectively.Results:A total of 88 study subjects completed the pre-intervention survey in this study, and a total of 79 study subjects were surveyed when they returned to the hospital for review at the end of 6 months of intervention, including 40 in the intervention group and 39 in the control group, with a missed rate of 10.23% (9/88). There was no significant difference in the score of FAD, FaMM, Kawasaki disease knowledge questionnaire before the intervention between the two groups ( P>0.05). The scores of FAD in the intervention group was (21.58 ± 4.60) points, which was lower than that in the control group (24.62 ± 5.28) points, and the difference was statistically significant ( t=2.73, P <0.05). The scores of FaMM in the intervention group was (46.83 ± 6.02) points, which was higher than that in the control group (42.72 ± 6.09) points, and the differences was statistically significant ( t=-3.01, P <0.05). The age of the child, and whether the child was an only child were the influencing factors of the difference in disease management ability, and the difference in the family function of the parents of the child, respectively (all P<0.05). Conclusions:Family management intervention can improve the disease management ability of the parents of children with coronary artery lesion, improve family function. In the future, targeted interventions can be conducted according to different ages of children, and different family members' composition in order to obtain better intervention effects.

Constructions of the scale of difficulty in the extraction of impacted mandibular third molars by using Delphi method / 北京大学学报(医学版)

OBJECTIVE@#To evaluate the relevant indicators affecting difficulty in the extraction of impacted mandibular third molars and score difficulty of different operation and risk indicators, so as to build an intuitive and accurate scale to help operators make more accurate analysis and prediction of difficulty before the operation.@*METHODS@#Based on literature and the clinical review, the difficulty indicators of tooth extraction were summarized. Firstly, 10 doctors from Peking University School and Hospital of Stomatology who had been engaged in alveolar surgery for a long time established an expert nominal group, and then rated whether the summarized indicators needed to be retained in the form of face-to-face questionnaires. A level 1 and 2 item frame for evaluating difficulty in the tooth extraction was formed after discussion; Then Delphi method was used to send a questionnaire to 30 experts by e-mail. After two rounds of scoring and modification, the scale of difficulty in the extraction of impacted mandibular third molars was formed.@*RESULTS@#The recycling rate of two rounds of questionnaires was 100.0%, which showed that the experts were very enthusiastic about the study; The authority coefficients (Cr) of the two rounds of Delphi expert consultation were both 0.92, which showed that the results were representative and authoritative. After two rounds of grading and revision, the variable coefficient (CV) decreased and the Kendall's concordance coefficient (W) increased, which were statistically significant: In the first round, the CV was 0.24 and W was 0.56 (P < 0.001), and in the second, the CV was 0.19 and W was 0.72 (P < 0.001), which indicated that there was a good convergence among the expert opinions. Finally, a scale of difficulty in the tooth extraction containing 12 items at level A and 37 items at level B was formed, including operation difficulty indicators, risk difficulty indicators and common difficulty indicators.@*CONCLUSION@#Based on comprehensive literature retrieval, the study has put forward the concept that difficulty in the extraction of impacted mandibular third molars is composed of operation difficulty and risk difficulty. Using Delphi method, the long-term clinical experience and professional knowledge of experts are transformed into quantitative indicators as a scoring scale. The scale has certain representativeness and authority.

After treatment, all scores increased in both groups (F > 11.676, P < 0.001). Four weeks and eight weeks after treatment, all scores were higher in the experimental group than in the control group (t > 2.122, P < 0.05). Conclusion:Intelligent rehabilitation training system could improve the upper limb and hand function and activities of daily living in stroke patients.

Association between carcinoembryonic antigen and metabolic syndrome in females / 中华内分泌代谢杂志

Objective:To explore the relationship between carcinoembryonic antigen (CEA) and metabolic syndrome (MetS) in females.Methods:The study involved 11337 women who visited the health check-up system in Health Management Center of a general hospital in Shandong province between January 2014 and December 2015. By grouping CEA by quartiles, logistic regression models were used to analyze the relationship between CEA and MetS and its components.Results:The prevalence of MetS was 16.4 %, and abnormal levels of CEA accounted for 7.1% of patients with MetS which exceeded the general physical examination population (3.2%). The level of CEA increased with the increase of the number of metabolic components. The multivariate logistic regression analysis showed that people with high levels of carcinoembryonic antigen were at higher risk for metabolic syndrome( χ2=18.374, P<0.01). Compared with the level of CEA in Q1, CEA levels in Q2, Q3, and Q4 were statistically related to MetS. The OR values were 1.25(95% CI 1.03-1.52), 1.25(95% CI 1.03-1.51) and 1.42(95% CI 1.17-1.72), respectively. Conclusion:For females, the study suggests that there is a relationship between CEA and MetS. The increased CEA level in patients with MetS should be carefully explained in clinical practice.

@#This study aimed to investigate the clinical efficacy of pulsed radiofrequency (PRF) of the dorsal root ganglion (DRG) with pain management as treatment of post-herpetic neuralgia (PHN). A total of 78 patients with PHN in the thoracolumbar region were randomly divided into two groups (n = 39 for each group): Group A, oral drug treatment only; Group B, DRG PRF of the thoracic spinal nerve combined with oral drug treatment. The numerical rating scale (NRS) scores of both groups were observed before treatment and at 1, 4, 8, and 12 weeks after treatment. The results showed that the NRS scores of both groups were significantly decreased after treatment (P < 0.05). In addition, the NRS score in Group B decreased significantly more than in Group A (P < 0.05). In conclusion, DRG PRF with pain management is a safe and effective treatment for elderly PHN patients, and it can quickly alleviate pain symptoms.

Newborn screening for Citrin deficiency and molecular characteristics of SLC25A13 variants in Guangzhou population / 中华实用儿科临床杂志

Objective:To investigate the sensitivity of newborn screening for neonatal intrahepatic cholestasis caused by Citrin deficiency (NICCD) based on tandem mass spectrometry and the carrying rate of known pathogenic variants of SLC25A13 in Guangzhou population. Methods:A total of 124 250 neonates born in Guangzhou from January 1, 2015 to December 31, 2018 were performed newborn screening for NICCD by tandem mass spectrometry technology. SLC25 A13 gene mutation analysis was performed to diagnose patients with suspected NICCD.The carrying rate of known pathogenic variants of the SLC25 A13 gene in the whole exon sequencing results of 2 395 healthy children in Guangzhou was retrospective analyzed. Results:Among the 124 250 screened neonates, 31 cases were screened positive for NICCD and one of them was confirmed.Three false negative patients with NICCD were found in this cohort.NICCD screening sensitivity was 25%(1/4 cases). All of the four patients were homozygous for c. 851_854del of SLC25A13.Among 2 395 controls, 60 cases were detected heterozygous variant of SLC25A13, including 8 kinds of reported pathogenic variants.The carrying rate of pathogenic alleles was 1/40 (60/2 395 cases). The estimated prevalence of citrin deficiency was about 1/6 400.The most common variant was c. 851_854del (56.7%, 34/60 cases), and the second was c. 790G>A (23.3%, 14/60 cases). The controversial variant c. 2T>C was detected in 113 children with heterozygous and 2 cases with homozygous and the carrying rate of c. 2T>C was 1/20(117/2 395 cases).
