Objective 　We aimed to find the distribution rule of traditional Chinese medicine(TCM) patterns of schizophrenia patients from the result of a large-sample, multicenter, cross-sectional study. Methods　From May 2020 to April 2021, we recruited schizophrenic patients in the following 12 subcenters in Beijing: The Third Affiliated Hospital of Beijing University of Traditional Chinese Medicine, The Third Hospital of Chaoyang District, Beijing Anding Hospital of Capital Medical University, Beijing Huilongguan Hospital, Daxing Xinkang Hospital, Changping Hospital of Integrated Chinese and Western Medicine, Shijingshan Mental Health Care Institute, Chuiyangliu Hospital of Tsinghua University, Yanqing District Psychiatric Hospital, Pinggu District Psychiatric Hospital, Guang'anmen Hospital of China Academy of Chinese Medical Sciences, and Dongzhimen Hospital of Beijing University of Chinese Medicine. In total, 4,734 schizophrenic patients(2,529 men and 2,205 women with an average age of 50. 81 years) were included, and their mental symptoms were evaluated using the TCM Pattern Scale, Positive and Negative Syndrome Scale, and the four diagnostic method ( inspection, listening and smelling, inquiry, and palpation and pulse taking). After finishing the Schizophrenic TCM Pattern Observation Form, the distribution of the patients′ TCM patterns was analyzed through the following steps:(Ⅰ) building a network diagram of all symptoms to extract the pattern locations and elements using association rules;(Ⅱ) combining the pattern locations with the pattern elements to form basic pattern, using the method of association rules, and Bayesian network, cluster analysis; and (Ⅲ) summarizing the patterns according to TCM theories and TCM expert consensus, and selecting the same patterns as the patterns of schizophrenia. Results 　Association rules were used to construct a relationship network diagram of 162 symptoms, and 16 basic TCM pattern were extracted. Among them, (Ⅰ) association rules extracted nine TCM patterns ( phlegm-fire disturbing mind, hyperactivity of heart-liver fire, stagnation of qi and blood stasis, hyperactivity of fire due to yin deficiency, kidney deficiency and liver depression, spirit confused by phlegm, yang deficiency of the spleen and kidney, deficiency of both the heart and spleen, and phlegm-qi stagnation with binding); (Ⅱ) cluster analysis extracted nine patterns (hyperactivity of heart-liver fire, phlegm fire burning yin, stagnation of qi and blood stasis, yin deficiency and blood insufficiency, yang deficiency of the spleen and kidney, stagnation of phlegmdampness, deficiency of both the heart and spleen, deficiency of kidney qi, and deficiency of bile qi); and (Ⅲ) the Bayesian network extracted 11 patterns(phlegm-fire disturbing mind, hyperactivity of heartliver fire, hyperactivity of fire due to yin deficiency, stagnation of qi and blood stasis, intermingled phlegm and heat, kidney deficiency and liver depression, spirit confused by phlegm, deficiency of both the spleen and kidney, deficiency of both the heart and spleen, disharmony between the heart and kidney, and liver-kidney deficiency). Finally, eight common patterns were summarized, including phlegm-fire disturbing mind, hyperactivity of heart-liver fire, stagnation of qi and blood stasis, hyperactivity of fire due to yin deficiency, spirit confused by phlegm, deficiency of both the heart and spleen, yang deficiency of the spleen and kidney, and kidney deficiency and liver depression. The clinical features of schizophrenic patients included negative symptoms (2,893 cases, 61. 11%) and positive symptoms (1,841 cases, 38. 89%). The former belongs to the TCM “ epilepsy syndrome” category, and the patterns of yang deficiency of the spleen and kidney(22. 94%), spirit confused by phlegm(17. 79%), deficiency of both the heart and spleen(13. 98%), and kidney deficiency and liver depression(6. 40%) are involved. The latter belongs to the TCM “manic psychosis syndrome” category, and the patterns of phlegm-fire disturbing mind(12. 63%), stagnation of qi and blood stasis(11. 03%), hyperactivity of fire due to yin deficiency(10. 25%), and hyperactivity of heart-liver fire(4. 99%) are involved. Conclusion　This study may provide a reliable basis for forming plans for TCM diagnosis and treatment of schizophrenia, which can be guided by the 8 TCM patterns from 4. 734 patients.

To evaluate the efficacy of a comprehensive TCM regimen on reducing the 2-year recurrence rate of major depressive disorder(MDD). Methods 　This large-scale multi-centered, prospective cohort study was conducted by recruiting MDD patients from 13 sub-centers nationwide from January 2017 to April 2018 with assistance of the Boshi Medical Cloud Data Management Platform . A comprehensive TCM regimen was used in the intervention of MDD patients. Three cohorts(TCM cohort, integrated Chinese and western medicine cohort, and western medicine cohort) were formed to observe the differences in the recurrence rate of MDD. According to the exposure time of the comprehensive TCM regimen intervention, the TCM cohort and the integrated Chinese and western medicine cohort were further divided into three groups with low, medium and high exposure levels respectively, and difference in the recurrence rate among those groups of different exposure levels was observed, so as to evaluate the long-term efficacy of the comprehensive TCM regimen in reducing the recurrence rate of MDD. Results　A total of 4 440 patients with MDD were included in the TCM cohort(1484 patients), western medicine cohort(1412 patients) and integrated Chinese and Western medicine cohort(1544 patients). The two-year recurrence rate was 25.5% in the TCM cohort, 35. 4% in the western medicine cohort, and 19. 3% in the integrated Chinese and western medicine cohort. Compared with the recurrence risk of the low-level exposure group in the Chinese medicine cohort, it was 41. 6% lower in the medium-level exposure group(HR = 0. 584, 95%CI(0.467 ~ 0.731), P <0. 001), and 71.3% lower in the high-level exposure group(HR =0. 287, 95%CI(0.214~0. 384), P<0. 001). Compared with the recurrence risk of the low-level exposure group in the integrated Chinese and western medicine cohort, it was 54. 3% lower in the medium-level exposure group(HR =0. 457, 95%CI(0. 352~0. 692), P<0. 001) and 75. 2% lower in the high-level exposure group(HR = 0. 248, 95%CI(0. 182 ~0. 337), P<0. 001). Conclusion　The comprehensive TCM regimen seems to reduce the 2-year recurrence rate of MDD. There is probably a close correlation between the exposure level of TCM intervention and the recurrence rate, and a longer exposure duration could possibly lead to a lower recurrence rate.

To establish a TCM information database for the prevention and treatment of major depressive disorder(MDD) based on cloud data technology, and to evaluate the clinical efficacy of traditional Chinese medicine(TCM) regimen in the prevention and treatment of suicide risk in MDD. Methods　A total of 4 440 patients with MDD who were inpatients or outpatients in 13 hospitals including TCM hospitals, integrated Chinese and Western medicine hospitals and psychiatric hospitals in 7 cities across the country were recruited, among which 2 513 patients without suicidal ideation were included in this cohort study. The data was collected from January 2017 to April 2018. Three groups of cohorts ( TCM, Western medicine, and integrated Chinese & Western medicine) were naturally formed. The follow-up interval was 3 months. Taking the appearance of suicidal ideation as the end event and the Montgomery-Asberg Depression Rating Scale(MARDS) as the evaluation tool in the follow-up, we assessed the patients′ dynamic status of depression and the occurrence of the end event. Results　A TCM cohort(896 patients), a Western medicine cohort(744 patients), and an integrated Chinese and Western medicine cohort(873 patients) were established with MDD patients without suicidal ideation at baseline, and the overall two-year incidence rates of suicidal ideation in the three groups were 34. 5% (309/896), 46. 9% (349/744), and 23. 0% (201/873) respectively. Compared with the Western medicine cohort, the risk of suicidal ideation was reduced in the TCM cohort by 33. 9% (HR = 0. 671, 95% CI(0. 575-0. 784), P <0. 001), and by 59. 4% (HR = 0. 406, 95%CI (0. 341-0. 483), P < 0. 001) in the integrated Chinese and Western medicine cohort. In the TCM cohort, compared with lowlevel TCM exposure time(TCM-ET), the risk of suicidal ideation was reduced by 47. 2%(HR =0. 528, 95%CI(0. 414-0. 674), P<0. 001), with medium-level TCM-ET, and by 81. 6% (HR =0. 184, 95%CI (0. 127-0. 267), P<0. 001), with high-level TCM-ET. In the integrated Chinese and Western medicine cohort, compared with the low-level TCM-ET time, the risk of suicidal ideation was reduced by 39. 9% (HR =0. 601, 95% CI(0. 438-0. 826), P<0. 001) with medium-level exposure time, and by 65. 9% (HR = 0. 341, 95%CI (0. 235-0. 495), P <0. 001) with high-level exposure time, indicating that a higher level of exposure time could reduce the suicidal risk. Conclusion　TCM, Western medicine, or integrated TCM and western medicine could all improve the depressive symptoms and suicidal ideation in MDD patients, and the application of TCM treatment seems to better reduce the probability of suicidal ideation in MDD patients than Western medicine treatment alone. The application of TCM treatment for over 6 months (medium-level or above TCM-ET) indicates a greater effect on the prevention of suicide in patients with MDD. [ABSTRACT FROM AUTHOR]

The analytical method of sliver, tin and boron in soil or sediment samples was developed by mixed mode inductively coupled plasma-mass spectrometry. A mixture of nitric acid, hydrochloric acid and hydrofluoric acid was utilized to digest the sample in a high-throughput closed microwave, and then the mass spectrometry sampling system was optimized and the mass spectrometry analysis mode for determination was adjusted. The mixed acid digestion solution could facilitate thorough digestion of refractory borosilicates and silicon-tin compounds in samples. Microwave sealed digestion method could improve the sample digestion efficiency and effectively avoid the loss of volatile element boron. Polytetrafluoroethylene (PTFE) atomizer, atomizer chamber and sapphire central tube could effectively reduce the background value of the instrument introduced by hydrofluoric acid solution medium corrosion quartz injection system. Using helium (He) as collision gas and the kinetic energy discrimination (KED) analysis of silver and tin could effectively reduce the interference of polyatomic ions, especially the interference of polyatomic ions formed by zirconium, niobium, zinc and oxygen, nitrogen and argon with higher geochemical abundance on 107Ag. The boron is basically free of polyatomic ion interference, so it could effectively improve the sensitivity of the method for boron by standard mode (STD). Subsequently, the detection limits of silver, tin and boron were 0.007, 0.12, 0.43 mg/kg, and the precision (RSD, n=12) and error (RE, n=12) of the method were 2.29%-9.53% and -9.95%-6.10%, respectively. Compared with the traditional atomic emission spectrometry method, this method has the advantages of simple process, high efficiency and low detection limit, which is suitable for the simultaneous analysis of multiple elements in large quantities of sample.

The academic statement of "earth as Pivot of Four Elements" was put forward by Huang Yuanyu in Sisheng Xinyuan (Elaboration of Writings of the Four Medical Sages). Huang raised that the spleen and stomach were the pivot, which governed yin, yang, ascending, descending, floating and sinking. Yin and yang moved around each other, and "pivot movement" theory was thus formed. He emphasized that spleen qi was the pivot of the ascending and descending of qi, which can regulate the five emotions. And the ascending of liver qi could arouse the mind, which became a great inspiration for later practitioners to distinguish and treat mental diseases. Postpartum depression belongs to mental disease in traditional Chinese medicine. This paper discussed the diagnosis and treatment of postpartum depression from the perspective of "pivot movement" theory, stating deficiency of qi and blood and the descending of liver and spleen qi as the basic pathogenesis, Using tonifying qi and blood and ascending liver and spleen qi as the therapeutic principle, and following the idea of "medicine pescribed should target at middle qi" as the apprach to making prescriptions. That may provide another ideas for clinical practice. [ABSTRACT FROM AUTHOR]
