This paper summarizes clinical experience in treating depression with a combined approach of acupuncture and herbal medicine under the guiding principle of deficiency and excess. Given the complex pathogenesis of depression， it is proposed that syndrome differentiation based on deficiency and excess should serve as the overarching principle. Acupuncture is prioritized， supplemented by Chinese herbal medicine. Acupuncture is based on the spirit-regulating protocol； for excess syndromes， it is combined with the calming and restoring protocol， while for deficiency syndromes， it is combined with the five zang organs tonification protocol. In cases of mixed deficiency and excess， the two protocols are alternated， and adjustments are made dynamically throughout the treatment based on syndrome evolution. Herbal prescriptions are also guided by the differentiation of deficiency and excess. For excess patterns， dispersion and clearance should be emphasized， focusing on soothing the liver， clearing heat， relieving irritability， regulating qi， transforming phlegm， and calming the mind； for deficiency patterns， tonification is emphasized， aiming to strengthen the spleen， nourish the blood， calm the spirit， tonify qi， and consolidate the root.

Objective To investigate the sputum metabolic profiles of patients with occupational coal workers' pneumoconiosis (CWP) by an untargeted metabolomics method, and to identify relevant differential metabolic pathways and potential biomarkers. Methods A total of 12 male patients with stage Ⅰ CWP were selected as the CWP group, and 16 healthy male individuals were selected as the control group, using a judgmental sampling method. Sputum metabolites of individuals in both groups were detected to perform non-targeted metabolomic analysis using the ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. Differential metabolites (DMs) and their pathways were screened using principal component analysis, partial least squares discriminant analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Potential biomarkers were analyzed and identified via the receiver operating characteristic curve (ROC). Results There were apparent metabolic alterations observed in sputum of CWP patients compared with healthy controls. In the positive ion mode, a total of 42 DMs were identified in sputum from CWP patients, including 19 downregulated and 23 upregulated metabolites. In the negative ion mode, a total of 25 DMs were identified in sputum from CWP patients, including 16 downregulated and 9 upregulated metabolites. KEGG enrichment analysis of sputum from CWP patients showed that seven DMs pathways were enriched in ABC transporters, histidine metabolism, phenylalanine metabolism, arachidonic acid metabolism, linoleic acid metabolism, purine metabolism, and oxidative phosphorylation, involving 26 DMs. ROC analysis indicated that 16(R)-hydroxyarachidonic acid, pyrophosphate, and 2-hydroxyphenylacetate of these 26 DMs may serve as potential biomarkers for CWP. Conclusion Sputum metabolomic profiles were altered in CWP patients compared with healthy controls. The potential biomarkers of CWP prevention and treatment are 16(R)-hydroxyarachidonic acid, pyrophosphate, and 2-hydroxyphenylacetate.

Objective:To compare the effects of glenosphere offset positions on the impingement-free range of motion (ROM) in reverse total shoulder arthroplasty (RTSA).Methods:Shoulder joint models were reconstructed using shoulder CT scans of 6 patients with primary osteoarthritis. RTSA was performed virtually according to standard surgical procedures, and shoulder movements were simulated. Reverse shoulder models were constructed with 2 lateral offsets (0 and 4 mm) and 6 positional offsets (center, inferior, posterior, anterior, anterior-inferior, and posterior-inferior). The impingement-free ROM and impingement sites for abduction-adduction, flexion-extension, total rotation (sum of internal and external rotation), and total ROM (sum of ROM in all movement modes) were evaluated.Results:All the 12 combinations of different glenosphere offsets achieved 50% of the original shoulder ROM in all movements. In the abduction-adduction motion with 0 and 4 mm lateral offsets, the anterior-inferior offset provided the largest ROM (94.4°±8.7° and 105.3°±6.9°, respectively), but there was no significant difference between the positions ( P>0.05). In the flexion-extension motion with 0 and 4 mm lateral offsets, the posterior-inferior offset showed the largest ROM (194.1°±6.9° and 196.9°±9.7°, respectively), but there was no significant difference between the positions ( P>0.05). In the total rotation motion with 0 and 4 mm lateral offsets, the anterior-inferior offset had the largest ROM (141.5°±5.9° and 160.6°±8.5°, respectively), showing significant advantages over the center, anterior, and posterior offsets ( P<0.05), but insignificant advantages over the inferior and posterior-inferior offsets ( P>0.05). In total ROM, the anterior-inferior offset provided the largest ROM. When the lateral offset was 0 mm, the anterior-inferior offset provided a ROM of 421.8°±16.4°, showing significant advantages over the center and posterior offsets ( P<0.05). Compared with the lateral glenosphere offset of 0 mm, the lateral glenosphere offset of 4 mm significantly improved total shoulder ROM (122.8°±10.6° versus 145.8°±4.8°) and total ROM (390.9°±11.6° versus 428.4°±19.8°) ( P<0.05). Conclusions:The anterior-inferior, inferior, and posterior-inferior glenosphere offsets can improve ROM in all movement patterns. The position and lateral offset of the glenosphere significantly affect the total rotation and total ROM of the shoulder joint. Specifically, the anterior-inferior and inferior offsets show significant advantages over the center position in total rotation and total ROM of the shoulder joint.

AIM: In order to bridge the gap between pharmacogenomic research and its clinical application, we propose the concept of genetic electronic identity, named "GeneFace", and developed an electronic information system which integrated "drug-gene" interactions and recommendations for personalized medicine. METHODS: Based on the self-developed Precision Medicine knowledgebase, which concludes drug directions, guidelines or important literatures with high level of evidence, we developed GeneFace with Java-based open-resource application framework Spring Boot, further developed a mobile App with cross-platform framework Uni-APP. RESULTS: The App includes six modules: genetic testing appointment, genetic knowledge introduction, individualized medication advice, medication records, Geneface interpretation, and Precision Medicine knowledgebase. By detecting the genotype of more than 300 gene loci upon first use, users import the results to form a personal "drug-gene identity card". Then scan or enter the drug name in "GeneFace", the App would automatically give corresponding medication recommendations, including: risks for possible adverse drug reactions, risks for reducing the efficacy or even ineffectiveness, and possibility for dose adjustment, etc., which increase the safety of clinical drug use. People can obtain pharmacogenomics knowledge and basic drug information in the "GeneFace" app. CONCLUSION: Development as a digital therapeutic product, the expanded application of GeneFace can rapidly promote clinical applications of basic pharmacogenomics research and significantly improve drug use safety, which creating a new model for accelerating the clinical application of personalized medicine.

IgA nephropathy(IgAN)is the most common primary glomerulonephritis in children and adolescents.It is an important cause of chronic kidney disease and end stage renal disease.The pathogenesis of IgAN has not been fully elucidated and it is thought to be associated with a multi-hit hypothesis, namely, increased levels of galactose-deficient IgA1(Gd-IgA1)(Hit 1); production of auto-antibodies directed against Gd-IgA1(Hit 2); formation of Gd-IgA1-containing immune complexes(Hit 3); the deposition of immune complexes in the glomerular mesangium resulting in glomerular injury(Hit 4). Gd-IgA1 is regarded as the initiator of the pathogenesis of IgAN.Core 1, β1, 3-galactosyltransferase(C1GALT1)is a key enzyme in the process of O-glycosylation of IgA.The reduction in the activity and/or gene expression of C1GALT1 is closely related to Gd-IgA1.This review will illustrate the role of C1GALT1 in the pathogenesis, diagnosis, treatment and prognosis of IgAN to provide molecular strategies for the clinical practice.

Objective:To resolve the issue of poor automatic segmentation of the bowel in women with pelvic tumors, a Dense V-Network model was established, trained and evaluated to accurately and automatically delineate the bowel of female patients with pelvic tumors.Methods:Dense Net and V-Net network models were combined to develop a Dense V-Network algorithm for automatic segmentation of 3D CT images. CT data were collected from 160 patients with cervical cancer, 130 of which were randomly selected as the training set to adjust the model parameters, and the remaining 30 were used as test set to evaluate the effect of automatic segmentation.Results:Eight parameters including Dice similarity coefficient (DSC) were utilized to quantitatively evaluate the segmentation effect. The DSC value, JD, ΔV, SI, IncI, HD (cm), MDA (mm), and DC (mm) of the small intestine were 0.86±0.03, 0.25±0.04, 0.10±0.07, 0.88±0.05, 0.85±0.05, 2.98±0.61, 2.40±0.45 and 4.13±1.74, which were better than those of any other single algorithm.Conclusion:Dense V-Network algorithm proposed in this paper can deliver accurate segmentation of the bowel organs. It can be applied in clinical practice after slight revision by physicians.

When applying deep learning to the automatic segmentation of organs at risk in medical images, we combine two network models of Dense Net and V-Net to develop a Dense V-network for automatic segmentation of three-dimensional computed tomography (CT) images, in order to solve the problems of degradation and gradient disappearance of three-dimensional convolutional neural networks optimization as training samples are insufficient. This algorithm is applied to the delineation of pelvic endangered organs and we take three representative evaluation parameters to quantitatively evaluate the segmentation effect. The clinical result showed that the Dice similarity coefficient values of the bladder, small intestine, rectum, femoral head and spinal cord were all above 0.87 (average was 0.9); Jaccard distance of these were within 2.3 (average was 0.18). Except for the small intestine, the Hausdorff distance of other organs were less than 0.9 cm (average was 0.62 cm). The Dense V-Network has been proven to achieve the accurate segmentation of pelvic endangered organs.

Objective:To explore the clinical effects of concentrated growth factor (CGF) combined with plasma albumin gel (PAG) in treating facial depressed scar.Methods:From January 2018 to June 2019, 14 patients in the First Affiliated Hospital of Zhengzhou University and 10 patients in Henan NO.3 Provincial People′s Hospital with facial depressed scar who met the inclusion criteria were admitted, and their clinical data were retrospectively analyzed by the method of case-control study. Based on the method of treatment, 8 patients (4 males and 4 females) aged 28.50 (25.50, 31.50) years were enrolled in CGF alone group, 8 patients (3 males and 5 females) aged 32.00 (28.50, 35.00) years were enrolled in PAG alone group, and 8 patients (5 males and 3 females) aged 33.50 (29.00, 35.75) years were enrolled in CGF+ PAG group. Suitable amount of CGF, PAG, and CGF+ PAG (mixed at a ratio of 1.0∶1.0-1.0∶1.5) prepared from autologous blood were injected subcutaneously via a single or multiple entrance (s) into the depressed scar of patients in CGF alone, PAG alone, and CGF+ PAG groups respectively to fill up the concavity, once every 4 weeks for a total of 3 times. Before the first treatment (hereinafter referred to as before treatment) and 3 months after the last treatment (hereinafter referred to as after treatment), the Goodman & Baron Acne Scar Grading System was used for scar grading, and the difference was calculated; the Anxiety Self-Rating Scale was used to score anxiety, and the difference was calculated. The Visual Analogue Score was used to score pain immediately after the first treatment. By one, two, and three months after treatment, the patients′ satisfaction to scar treatment was scored, and the Global Aesthetic Improvement Scale was used to score the scar improvement. Adverse reaction of patients after treatment was monitored. Data were statistically analyzed with Fisher′s exact probability test, Kruskal-Wallis H test, Mann-Whitney U test, Bonferroni correction, and Wilcoxon signed rank sum test. Results:(1) The scars of patients in the three groups were all graded 4.00 (4.00, 4.00) before treatment ( χ2<0.001, P>0.05). By three months after treatment, compared with 2.00 (1.25, 2.00) of CGF alone group, the scar grades of patients in PAG alone group and CGF+ PAG group (3.00 (2.00, 3.00) and 1.00 (1.00, 1.00), respectively) had no significant change ( Z=2.199, 2.003, P>0.05). The scar grade of patients in CGF+ PAG group was significantly lower than that in PAG alone group ( Z=3.229, P<0.01). Compared with those before treatment, the scar grades of patients in CGF alone group, PAG alone group, and CGF+ PAG group were significantly reduced three months after treatment ( Z=2.588, 2.598, 2.640, P<0.05 or P<0.01). The difference in scar grade before and after the treatment was significantly higher in CGF+ PAG group than in PAG alone group ( Z=3.229, P<0.01). (2) The anxiety scores of patients in the three groups were similar before treatment and 3 months after ( χ2=2.551, 2.768, P>0.05). Compared with those before treatment, the anxiety scores of patients in CGF alone group, PAG alone group, and CGF+ PAG group were significantly reduced three months after treatment ( Z=2.395, 2.527, 2.533, P<0.05). The differences in anxiety score before and after the treatment were similar among the three groups ( χ2=1.796, P>0.05). (3) The pain scores of patients in the three groups were similar immediately after the first treatment ( χ2=0.400, P>0.05). (4) By one and two month (s) after treatment, the patients′ satisfaction scores to scar treatment in the three groups were similar ( χ2=2.688, 5.989, P>0.05). By three months after treatment, the patients′ satisfaction score to scar treatment in CGF+ PAG group was significantly higher than that in PAG alone group ( Z=2.922, P<0.01). Compared with those one month after treatment within the same group, the patients′ satisfaction scores to scar treatment in CGF alone group, PAG alone group, and CGF+ PAG group were significantly increased two and three months after treatment ( Z=1.121, 2.392, 2.000, 2.828, 2.449, 2.598, P<0.05 or P<0.01). Compared with those two months after treatment within the same group, the patients′ satisfaction scores to scar treatment in CGF alone group, PAG alone group, and CGF+ PAG group were significantly increased three months after treatment ( Z=2.271, 2.000, 2.646, P<0.05 or P<0.01). (5) One month after treatment, the scar improvement scores of patients in the three groups were similar ( χ2=4.438, P>0.05). Two months after treatment, the scar improvement scores of patients in CGF alone group and CGF+ PAG group were 2.00 (2.00, 2.75) and 2.00 (2.00, 2.00) points, respectively, which were significantly higher than 1.00 (1.00, 1.00) point of PAG alone group ( Z=3.303, 3.771, P<0.01). Three months after treatment, the scar improvement score of patients in CGF+ PAG group was 3.00 (3.00, 3.00) points, which was significantly higher than 2.00 (2.00, 2.75) points of CGF alone group and 1.00 (1.00, 2.00) points of PAG alone group ( Z=2.450, 3.427, P<0.05 or P<0.01). Compared with those one month after treatment within the same group, the scar improvement scores of patients were significantly higher in CGF alone group and CGF+ PAG group two and three months after treatment and in PAG alone group three months after treatment ( Z=2.828, 2.828, 2.530, 2.640, 2.121, P<0.05 or P<0.01). Compared with that two months after treatment within the same group, the scar improvement score of patients in CGF+ PAG group was significantly higher three months after treatment ( Z=2.449, P<0.05). (6) After injection, all patients in the three groups had slight redness and swelling at the needle prick point and no other adverse reactions. Conclusions:CGF combined with PAG can reduce the scar grading, anxiety of patients, and enhance patients′ satisfaction and scar improvement in the treatment of patients with facial depressed scar. The combined CGF+ PAG injection, without significant adverse reactions, is better than single component injection and is worthy of clinical application.

Objective:To compare the efficacy and safety of triamcinolone acetonide (TA) alone and in combination with 5-fluorouracil (5-FU) for treating keloids using meta-analysis.Methods:Databases including PubMed, Embase, and Cochrane Library were retrieved with the search terms of " triamcinolone acetonide, 5-fluorouracil, glucocorticoid, fluorouracil, keloid, scar, TAC, 5-FU, hypertrophic scar " and databases including Chinese Journal Full- Text Database, Chinese Biomedical Database, and Wanfang Data were retrieved with the search terms of "曲安奈德,瘢痕疙瘩, 5-氟尿嘧啶,糖皮质激素,增生性瘢痕" in Chinese to obtain the publicly published randomized controlled trials about the effects of TA alone and in combination with 5-fluorouracil for treating keloids from the establishment of each database to august 2019. The outcome indexes included effective proportion of treatment, incidence proportion of adverse reactions, and recurrence proportion of keloids. RevMan 5.3 and Stata 14.0 statistical software were used to conduct a meta-analysis of eligible studies. Results:A total of 1 326 patients with keloids were included in 14 studies, including 668 patients in TA+ 5-fluorouracil group whose keloids were injected with TA and 5-fluorouracil and 658 patients in TA alone group whose keloids were injected with TA alone. A total of 7 articles achieved 1 to 3 points in modified Jadad score, while 7 articles achieved 4 to 7 points in modified Jadad score. Patients in TA+ 5-fluorouracil group had a higher effective proportion of treatment than that of TA alone group (relative risk=1.28, 95% confidence interval=1.16-1.41, P<0.01). Subgroup analysis showed that the quality of the included literature and ethnic factors might be the source of heterogeneity in effective proportion of treatment. Patients in TA+ 5-fluorouracil group had a lower incidence proportion of adverse reactions than that of TA alone group (relative risk=0.44, 95% confidence interval=0.25-0.75, P<0.01). Patients in TA+ 5-fluorouracil group had a lower recurrence proportion of keloids than that of TA alone group (relative risk=0.25, 95% confidence interval=0.14-0.44, P<0.01). There was no publication bias in incidence proportion of adverse reactions ( P>0.05), while the effective proportion of treatment and recurrence proportion of keloids had publication bias ( P<0.05). Conclusions:TA combined with 5-fluorouracil is more effective than TA alone for treating keloids, with less incidence of adverse reactions and recurrence.
