Objective:To investigate the medication rules of Xin'an medicine for the treatment of melancholia and further analyze the medication ideas of Xin'an physicians in the treatment of melancholia.Methods:The documents of Xin'an physicians treating melancholia in the fifth edition of the Chinese Medical Code and the online database of ancient Chinese medicine were retrieved. Excel was used to extract the prescription information to establish the database. R language was used to analyze the data regarding the medication frequency, nature and taste, association rules, and clustering of the traditional Chinese medicine used in the prescription. Results:A total of 127 effective prescriptions were sorted out, and 177 kinds of Chinese medicines were used with a total medication frequency of 1 031 times. The top three Chinese medicines with the highest frequency of use were Poria cocos (57 times), Licorice (46 times), and Paeonia Lactiflora (40 times). The main nature of herbs was plain and warm nature. The warm herbs were the most frequently used (298 times). The first five flavors of the herbs which were the most used were pungent taste (475 times, 28.70%), bitter taste (459 times, 27.73%), and sweet taste (453 times, 27.37%). The commonly used herbs with confidence coefficient > 0.800 were Licorice + Angelica sinensis, Licorice + Angelica sinensis and Paeonia Lactiflora, Licorice + Bupleurum, Licorice + Atractylodes macrocephala, Cyperus root + Ligusticum Chuanxiong, Angelica sinensis + Atractylodes macrocephala and Licorice, Paeonia Lactiflora + Angelica sinensis and Poria cocos, Licorice + Angelica sinensis and Poria cocos, Licorice + Atractylodes macrocephala and Angelica sinensis, Licorice + Bupleurum and Paeonia Lactiflora, Licorice + Atractylodes macrocephala and Ginseng, Licorice + Ginseng and Angelica sinensis, Cyperus root + Medicated leaven, Ginseng + Astragalus mongholicus, Licorice + Astragalus mongholicus.Conclusion:Xin'an medicine for the treatment of melancholia mainly uses pungent, bitter, sweet, and warm herbs. It can adjust the chill and fever, Yin and Yang of the human body, diminishes the urgency, and regulates the flow of Qi.

Correlation between stomach disharmony and daily diets among students of Chinese medicine colleges and universities in China / 中国基层医药

Objective:To analyze the correlation between gastric disharmony and daily eating behaviors in college students, and to provide intervention measures for improving gastric disharmony among college students.Methods:From April 10 to 30, 2021, 3 825 college students from five Chinese medicine colleges and universities in China were selected for this study using the multi-level sampling method. The information regarding college student's general situation, daily eating behavior, and stomach disharmony was collected by questionnaire.Results:A total of 3 700 valid questionnaires were collected, with an effective response rate of 96.73%. The average age was (20.0 ± 3.0) years, and 66.41% of college students included in this study were female. Students with different characteristics had different gastric disharmonies and eating behaviors, and gastric disharmony was correlated with eating behavior. Multivariate analysis results showed that snacking ( OR = 1.11, 95% CI: 1.02-1.21), partial eclipse ( OR = 1.12, 95% CI: 1.00-1.26), picky eaters ( OR = 1.23, 95% CI: 1.08-1.41), and supper ( OR = 1.19, 95% CI: 1.04-1.36) were positively correlated with gastric disharmony. Eating regular meals ( OR = 0.86, 95% CI: 0.79-0.94) and 80% fullness ( OR = 0.89, 95% CI: 0.81-0.98) were negatively correlated with gastric disharmony. Conclusion:Poor eating behaviors may be an important factor leading to gastric disharmony.

Correlation between unhealthy dietary behaviors and traditional Chinese medicine constitution among students from colleges and universities of traditional Chinese medicine / 中国基层医药

Objective:To investigate the correlation between unhealthy dietary behaviors and traditional Chinese medicine constitution among students from colleges and universities of traditional Chinese medicine.Methods:College students from Shandong University of Traditional Chinese Medicine, Anhui University of Chinese Medicine, Henan University of Chinese Medicine, Shaanxi University of Chinese Medicine and Gansu University of Chinese Medicine were collected during April 10-30, 2021 and grouped taking classes as units. Research subjects were obtained by multistage sampling. Their dietary behaviors, traditional Chinese medicine constitution and demographic characteristics were surveyed using questionnaires. Statistical analysis was performed using SPSS23.0 software.Results:A total of 3825 college students were investigated and 3 700 valid questionnaires (96.7%) were collected. Peaceful constitution was detected in 7.9% of included college students. There was significant difference in peaceful constitution among studies of different sexes and different body types ( P < 0.05). There were significant differences in attention to diet, physical exercise and body weight control, out-of-control diet, excessive eating and drinking, denying body shape, and dissatisfaction with body shape between patients with peaceful and unbalanced constitutions. Multivariate analysis showed that attention to diet ( OR = 1.38, 95% CI: 1.14-1.68), physical exercise and body weight control ( OR = 1.19, 95% CI: 1.03-1.39), dissatisfaction with body shape ( OR = 1.26, 95% CI: 1.10-1.45) were conducive to the development of peaceful constitution. Conclusion:Students from colleges and universities of traditional Chinese medicine have a low proportion of developing peaceful constitution. Dietary behaviors may be an important factor that affects the development of peaceful constitution.

Gene Mutation of RANTES and CCR5 in Systemic Lupus Erythematosus / 中华皮肤科杂志

Objective To evaluate the gene mutation of RANTES and CCR5 in SLE and its significance. Methods One hundred and forty-six definitive SLE patients and 159 controls were collected. SNPs of RANTES promoter and polymorphism of CCR5 were performed by PCR or PCR/RFLP assay, and further confirmed by direct DNA sequencing. Results The frequence of RANTES-403G/G compounded with 28C/C and CCR5/CCR5 was significantly different between SLE and control groups (72.6% vs 58.5%, P 0.05). Conclusions These results indicate that the two SNPs are linkage disequilibrium. Interaction of two SNPs in RANTES and CCR5 is related with SLE. RANTES-403G/G compounded with 28C/C and CCR5/CCR5 may be one of risk factors of SLE. RANTES-403A is probably related with renal damage of SLE.

Study on the Feasibility for ARIMA Model Application to Predict Malaria Incidence in an Unstable Malaria Area / 中国寄生虫学与寄生虫病杂志

Objective To explore the application of seasonal time series ARIMA model in prediction of malaria incidence in an unstable malaria area. Methods SPSS13.0 software was used to construct the ARIMA model based on the monthly malaria incidence of Huaiyuan and Tongbai counties in Huaihe River Valley, from Jan. 1998 to Dec. 2005, with consideration of residual un-correlation and concision. Akaike′s information criterion (AIC) and Bayesian information criterion (BIC) were used to confirm the fitness of model. The constructed model was then applied to predict the monthly malaria incidence in 2006 and the incidence from ARIMA model was compared with the actual incidence, so as to evaluate the model′s validity. Malaria incidence of 2007 was predicted by ARIMA model based on malaria incidence from 1998 to 2006. Results Statistics assisted estimation of the significance of the fitted autoregressive and seasonal moving average coefficients (AR1=0.512, SMA1=0.609, P
