ObjectiveTo investigate the effects of Tongxinluo capsules on traditional Chinese medicine （TCM） syndrome elements and major adverse cardiovascular events （MACEs） in patients with chronic coronary syndrome of Qi deficiency and blood stasis type. MethodsA multicenter and prospective cohort study was conducted. The intervention of Tongxinluo Capsules was used as the exposure factor， and the patients were divided into an exposure group （integrated traditional Chinese and western medicine treatment group） and a non-exposure group （western medicine treatment group）. The patients were followed up for one year. The TCM syndrome element scores were assessed by using a syndrome element diagnosis scale on the day of enrollment and in the third， sixth， and twelfth months， and the incidence of MACE within one year was recorded. ResultsA total of 186 patients were included， with 128 patients in the exposure group and 58 patients in the non-exposure group. There was no significant difference in baseline data between the two groups. Compared with those in the pretreatment period for each group， the Qi deficiency and blood stasis syndrome scores in the treatment and follow-up period were significantly improved （P<0.05）. Compared with the non-exposure group， the exposure group exhibited significantly decreased Qi deficiency syndrome scores in the treatment and follow-up period （P<0.01） and significantly reduced blood stasis syndrome scores in the sixth month （P<0.05）. In the remaining follow-up period， there was no statistically significant difference between the two groups. Compared with that of the non-exposure group， during the treatment period （the third month）， the difference in Qi deficiency and blood stasis syndrome scores of the exposure group was statistically significant （P<0.05， P<0.01）. At the end of the follow-up period， patients in the non-exposure group had a MACE probability of 6.90% （4/58）， higher than 3.13% in the exposure group （4/58）. Compared with patients with angina pectoris who used conventional medicine， patients administered with Tongxinluo Capsules had a relative risk（RR） of 0.45 ［95%confidence interval（95%CI） 0.12-1.75， P=0.26］. There was no significant difference in the incidence of MACE within one year between the two groups. ConclusionTongxinluo capsules can improve the degree of Qi deficiency in patients with chronic coronary syndrome in the short term， and the improvement effect of blood stasis syndrome appears in the medium and long term. They can better improve the Qi deficiency syndrome in the long term. Within one year， the incidence of MACE in the exposure group was lower than that in the non-exposure group.

Objective To investigate the geographical distribution and seasonal fluctuations of visceral leishmaniasis vectors sandflies in Henan Province in 2023, so as to provide insights into the prevention and control of visceral leishmaniasis vectors. Methods A total of 23 counties (districts) were sampled from 18 cities of Henan Province from May to September, 2023 as sandfly surveillance sites, and sandflies were captured using human capture and light trapping methods. Following morphological identification, the changes in the sandfly density were calculated at different months and in different breeding habitats. Results A total of 406 light traps were set at sandfly surveillance sites in Henan Province from May to September, 2023, and a total of 3 137 female sandlies were captured, with an average density of 7.73 sandlies/(light·night). A total of 1 494 Phlebotomus chinensis sandflies were captured, including 1 222 female sandflies, with an average density of 3.01 sandflies/(light·night), and the highest density of P. chinensis was found in Gongyi City [17.00 sandflies/(light·night)]. A total of 5 544 sandflies were captured using the human capture method, including 230 P. chinensis, and the density of P. chinensis appeared a unimodal distribution, with a peak in early July [5.81 sandflies/(light·night)]. Among different breeding habitats, the highest P. chinensis density was detected in pigpens [4.50 sandflies/(light·night)]. Conclusions P. chinensis was predominantly distributed in hilly areas of northern and central-western Henan Province in 2023, and the sandfly density appeared a unimodal distribution. Intensified monitoring of visceral leishmaniasis vectors is recommended.

Objective To characterize the species of common sandflies in Henan Province using DNA barcoding with cytochrome c oxidase subunit I (COI) gene as the molecular marker, and to analyze the genetic polymorphisms of sandflies, so as to provide insights into visceral leishmaniasis prevention and control in Henan Province. Methods Sandfly specimens were sampled from 13 sandflies surveillance sites from 2021 to 2023 in Anyang City, Zhengzhou, Luoyang and Xuchang cities (Zhengzhou-Luoyang-Xuchang areas) where visceral leishmaniasis cases were reported and in Jiaozuo and Xinxiang cities (Jiaozuo-Xinxiang areas) without visceral leishmaniasis cases reported. Genomic DNA was extracted from a single sandfly, and COI gene was amplified. The amplification product was subjected to bidirectional sequencing. Following sequence assembly, the species of sandflies was characterized through sequence alignment using the BLAST tool. The intra-specific and inter-specific genetic distances of sandflies were estimated among different areas using the software Mega 11, and phylogenetic trees were created. The polymorphisms of nucleotide sequences in the sandflies COI gene were estimated using the software DnaSP. The fixation index (F_ST) of different geographical isolates of sandflies was calculated using the Arlequin software, and the gene flow value (Nm) was used to measure the gene flow in the sandflies populations. In addition, the population genetic structure of different geographical populations of Phlebotomus chinensis was analyzed using the STRUCTURE software. Results A total of 978 sandflies were collected from 13 sandflies surveillance sites in Zhengzhou-Luoyang-Xuchang areas, Jiaozuo-Xinxiang areas and Anyang City of Henan Province from 2021 to 2023, and 475 sandflies were randomly sampled for subsequent detections. A total of 304 Ph. chinensis, 162 Se. squamirostris and 9 Se. bailyi were identified based on molecular biological detection of the COI gene, and Se. bailyi was reported for the first time in Henan Province. The intraspecific genetic distances of sandflies were 0.000 to 0.040, and the inter-specific genetic distances ranged from 0.133 to 0.161. Phylogenetic analysis revealed that each of the three sandfly species was clustered into a clade. The genetic polymorphisms of Ph. chinensis populations varied among different areas, with the highest haplotype diversity (0.966 ± 0.007) and the greatest nucleotide diversity (0.011) in Zhengzhou-Luoyang-Xuchang areas, and the lowest haplotype diversity (0.720 ± 0.091) and nucleotide diversity (0.004) in Anyang City. The dominant haplotype of Ph. chinensis populations was Pch_Hap_2 in Anyang City and Jiaozuo-Xinxiang areas, with moderate genetic differentiation (0.05 < F_ST < 0.15) and frequent gene exchange (Nm value > 1) between Ph. chinensis populations sampled from Anyang City, and Jiaozuo-Xinxiang areas. Population genetic structure analysis showed that the dominant component of Ph. chinensis populations was K5 in Anyang City and Jiaozuo-Xinxiang areas. No obvious dominant haplotype was observed in Ph. chinensis populations sampled from Zhengzhou-Luoyang-Xuchang areas, which had very high genetic differentiation (F_ST > 0.25) and little gene exchange (Nm value < 1) with Ph. chinensis populations from Anyang City, and Jiaozuo-Xinxiang areas, with K3 as the dominant component. In addition, there was no significant difference in the genetic polymorphism level among Se. squamirostris populations from the three areas. Conclusions There are Ph. chinensis, Se. squamirostris and Se. bailyi in Henan Province, and S. bailyi is recorded for the first time in Henan Province by molecular biological assays. There are different levels of genetic differentiation and gene exchange among P. chinensis populations in different areas of Henan Province.

ObjectiveTo investigate the effect of Tongxinluo capsules on the use of anti-ischemic drugs in patients with chronic coronary syndrome （CCS） of Qi deficiency and blood stasis. MethodA multicenter，prospective cohort study was conducted，with Tongxinluo capsules intervention as the exposure factor. Patients were divided into an exposed group （combination of traditional Chinese and western medicine） and a non-exposed group （western medicine alone），and followed up for one year. The use of anti-ischemic drugs was observed on the day of enrollment and at 3，6，12 months. ResultA total of 186 patients were enrolled，with 128 in the exposed group and 58 in the non-exposed group. There were no statistically significant differences in baseline characteristics between the two groups. At the 3-month follow-up，the types of first-line anti-ischemic drugs used in the exposed group were significantly fewer than those in the non-exposed group （P<0.01），and this difference remained statistically significant at 6 months （P<0.05） but was no longer significant at 12 months. At the 3- and 6-month follow-ups，there were no significant differences between the two groups in the types of second-line anti-ischemic drugs used. However，at the 12-month follow-up，the types of second-line anti-ischemic drugs used in the exposed group were significantly fewer than those in the non-exposed group （P<0.01）. At the 3-month follow-up，both groups showed a reduction in the types of first-line anti-ischemic drugs used compared to baseline （P<0.05），with a more pronounced reduction in the exposed group （P<0.05）. At the 6-month follow-up，the exposed group showed a significant reduction in the types of second-line anti-ischemic drugs used compared to baseline （P<0.05），while no significant changes were observed in the non-exposed group. At the 12-month follow-up，the difference in the types of second-line anti-ischemic drugs between the exposed and non-exposed groups was statistically significant （P<0.05），while there was no significant difference in the types of first-line anti-ischemic drugs. ConclusionTongxinluo capsules can effectively reduce the use of anti-ischemic drugs in patients with CCS of Qi deficiency and blood stasis.

Objective To evaluate the accuracy of bioelectrical impedance analysis(BIA)in measurement of appendicular skeletal muscle mass(ASM)of adults.Methods A total of 836 adults aged 18-42 years were recruited in Guangzhou using a convenient sampling method from April 2021 to September 2022.ASM was measured using BIA and Dual-energy X-ray absorptiometry(DXA).Using DXA as the standard method,the consistency between the BIA and DXA measurements was evaluated by intra-class correlation coefficients(ICCs)and Bland-Altman analysis in logarithmically transformed data,in order to evaluate the accuracy of BIA in ASM measurement.Receiver operating characteristic curve was plotted to evaluate the diagnostic value of BIA for screening low muscle mass.Results A total of 774 individuals were included for analysis finally.ICCs for ASM measured by BIA and DXA were 0.774 and 0.667 in males and females,respectively.Mean ratios(limits of Agreement)of ASM were 0.94(0.80-1.10)and 0.91(0.78-1.05)in males and females,respectively.Area under curve of BIA for screening low muscle mass were 0.91 and 0.94 in males and females,respectively.The optimal cut-off values of Z-score by BIA for males and females were-0.57 and-0.66,respectively.Sensitivity and specificity for males were 82.5%and 86.0%,while being 86.8%and 93.8%,for females.Conclusion BIA shows a moderate consistency with DXA for measuring ASM in adults.Furthermore,BIA yields a good diagnostic value in identifying low muscle mass in adults aged 18-42 years.

Objective:To investigate the relationship among mental health,maternal negative emotion and mother-child attachment in preschoolers.Methods:A total of 591 mothers of preschoolers from 8 kindergartens were selected.The Preschoolers Mental Health Scale(PMHS)was used to evaluate mental health of the preschool-ers,the Self-rating Depression Scale(SDS)and Self-rating Anxiety Scale(SAS)were used to evaluate maternal negative emotions,and Maternal Object Relationship Scale-Short Form(MORS)was used to evaluate mother-child attachment.Results:The scores of SDS and SAS were positively correlated with the total scoresand scores of each dimension of PMHS(r=0.69-0.93,Ps＜0.001).The maternal SDS and SAS scores were positively associated with total PMHS scores(β=0.38,0.52).The products of maternal SAS scores and MORS scores were negatively associated with the total PMHS scores(β=-0.12).Conclusion:Preschoolers mental health is closely related to a maternal negative emotion and mother-child attachment.

Objective:To observe the effects of moxibustion on the levels of glucose-6-phosphate dehydrogenase(G6PD)and reduced nicotinamide adenine dinucleotide phosphate(NADPH)in the plasma and spleen and the CD4+T-cell number in the spleen of rats with adjuvant arthritis,thus to explore the mechanism in rheumatoid arthritis(RA)treatment with moxibustion by regulating the CD4+T-cell proliferation through G6PD-mediated pentose phosphate pathway. Methods:Twenty-seven male Sprague-Dawley rats were randomly divided into a blank group,a model group,and a moxibustion group,with 9 rats in each group.Incomplete Freund's adjuvant was used to induce inflammation in the model group and the moxibustion group.The blank group and the model group were not intervened.In the moxibustion group,suspended moxibustion was performed at bilateral Zusanli(ST36),Guanyuan(CV4),and Ashi points for 30 min,once a day for 24 times in total.Hematoxylin-eosin staining was used to evaluate the histopathological changes of rat synovial tissue;the swelling degree of the rat toes was observed by measuring the toe volume;G6PD and NADPH in the spleen and plasma were detected by Western blotting and enzyme-linked immunosorbent assay.Flow cytometry was used to detect the CD4+T-cell number in the spleen. Results:Compared with the blank group,the levels of G6PD and NADPH in the plasma and spleen and the CD4+T-cell number in the spleen were significantly increased in the model group(P<0.01 or P<0.05).Compared with the model group,the NADPH level in the spleen and plasma and the CD4+T-cell number in the spleen in the moxibustion group decreased significantly(P<0.05 or P<0.01),and the G6PD level in the plasma decreased significantly(P<0.05),but there was no significant difference in the G6PD level in the spleen(P>0.05). Conclusion:Moxibustion can regulate immunity and improve joint synovial inflammation in RA.The mechanism may be that the G6PD-mediated pentose phosphate pathway reduces the production of metabolite NAPDH in CD4+T cells,thereby inhibiting the proliferation of naive CD4+T cells.

In recent years, researches have shown that microglia drive their phenotype polarization through energy and substance metabolism reprogramming, thereby exerting pro-inflammatory or anti-inflammatory effects, which is closely associated with the risk of ischemic stroke. Their specific metabolic pathways involve glucose metabolism, lipid metabolism, and amino acid metabolism. This article reviews regulatory mechanisms of microglia metabolism after ischemic stroke and their role in ischemic stroke.

Objective To explore the effect of jogging on the patients with depression disorder of liver-stagnation and spleen-deficiency.Methods 100 patients with liver-stagnation and spleen-deficiency depression disorder were randomly selected from Tongde Hospital of Zhejiang Province from March to September 2022.They were divided into observation group and control group(50 cases each)by random number table method.The control group received conventional antidepressant drug treatment,and the observation group was given jogging exercise regimen on the basis of the control group:exercise at least 4 times a week,30-60 min each time,and the heart rate was maintained at 110-120 times/min for 4 weeks.The depressive disorder of the patients was assessed by Zung's Self-rating Depression Scale(SDS)and 17-item Hamilton Depression Scale(HAMD-17).Results After jogging exercise intervention,the total effective rate of the observation group was 94%,which was significantly higher than that of the control group 80%(P<0.05).HAMD-17 score was significantly lower in the observation group than in the control group after intervention(F=12.575,P<0.05).The scores of cognitive impairment,block and sleep disturbance in the observation group were significantly lower than those in the control group after intervention(F=12.575,P<0.05).The body weight factor scores of the observation group and the control group were significantly higher after intervention than before intervention(P>0.05).Conclusions Jogging exercise intervention therapy can significantly improve the depression of patients with liver-qi and spleen-deficiency depression disorder,and jogging can be an effective method to prevent and treat depression disorder.
