OBJECTIVETo study the clinical effect of "Jin's three-needling" in the treatment of generalized anxiety disorder.

METHODSFifty-eight patients with generalized anxiety were randomly assigned to two groups equally, the medication group treated with anti-anxiety drugs and the acupuncture group with "Jin's three-needling". The treatment course was 6 weeks. The clinical effects were evaluated with Hamilton anxiety scale (HAMA), clinical global impression (CGI), and treatment emergent symptom scale (TESS) before treatment and at the end of 2nd, 4th, 6th week of the treatment course. The concentration of 5-hydroxytryptamine (5-HT) in platelet, and plasma levels of corticosterone (CS) and adrenocorticotropic hormone (ACTH) were measured with high performance liquid chromatography-electrochemical detection (HPLC-ED) method before and after treatment.

RESULTSThe clinical effects in the two groups were equivalent, while the adverse reaction found in the acupuncture group was less than that in the medication group (P < 0.05). The platelet concentration of 5-HT and plasma ACTH level decreased significantly in both groups after treatment with insignificant difference between the group (P < 0.05). The plasma CS level had no obvious change in the two groups after treatment as compared with that before treatment respectively.

CONCLUSION"Jin's three-needling" shows similar curative effect on generalized anxiety to routine Western medicine but with less adverse reaction, which may be realized through regulating the platelet 5-HT concentration and plasma ACTH level.

To develop an analytic method for qualitative and quantitative analysis of dodecatetraenamides A, B in 42 samples of two official species of Asari Radix et Rhizoma( ARR) (37 samples of Asarum heterotropoides var. mandshuricum with different collection time and 5 samples of Asarum sieboldiivar. seoulense). The HPLC-IT-TOF-MS/MS methods for the qualitative and UPLC-PDA methods for the quantitative analysis were established. Dodecatetraenamides A, B were identified by comparing the retention time, UV absorption spectrum and quasi-molecular ion peak [ M + H]+ with the reference compound using HPLC-IT-TOF-MS/MS. The content of dodecatetraenamides A and B in ARR were determined by UPLC-PDA. The separation was successfully carried out on a ACQUITY UPLC BEH C18 (2.1 mm x 100 mm, 1.7 µm) column eluted with mobile phases of water (A) and acetonitrile (B) in gradient program (0-3 min, 35% B; 3-5 min, 35%-36% B; 5-6 min, 36%-43% B; 6 min-11 min 43% B; 11-12 min, 43%-100% B). The column temperature was 45 °C, and the detection wavelength was set at 254 nm. The flow rate was 0.6 mL · min(-1). On one level mass spectrometry scanning, the results showed that the quasi-molecular ion [M + H] + of both dodecatetraenamides A and B were m/z 248.20. The quantitative method with UPLC-PDA has made the baseline separation of the constituents, which were reported as mixtures in the most literatures. The average recovery of dodecatetraenamides A and B were 97.90% and 99.86%, the relative standard deviation were 0.4% and 1.1%, respectively. The contents of dodecatetraenamides A, B in all ARR samples was in the range of 0.11-3.89 and 0.24-6.65 mg · g(-1). Their contents reduced with the extension of storage time. Compared with the samples of 2013, the average content of the two constituents in the samples collected in year 2002-2003 reduced 34% and 36%, respectively (P < 0.05). Compared the A. sieboldii var. seoulense and A. heterotropoides var. mandshuricum with the same collective time and production area, the average contents of the two constituents in latter were up to (1.59 ± 0.75) mg · g(-1) and (2.90 ± 1.17) mg · g(-1), respectively, significantly higher than that in A. sieboldii var. seoulense (dodecatetraenamide A were (0.78 ± 0.52) mg · g(-1), dodecatetraenamide B were (1.69 ± 0.83) mg · g(-1)) (P < 0.05). The content of the dodecatetraenamide A in overground part was in the range of 0.11-0.33 mg · g(-1), dodecatetraenamide B was 0. 24-0.60 mg · g(-1), which were much lower than that of the underground part of ARR (dodecatetraenamide A was in the range of 0.73-3.89 mg · g(-1), dodecatetraenamide B was 2.11-6.24 mg · g(-1)). The method was certified to be simple, accurate and reliable and could be used for qualitative and quantitative analysis of dodecatetraenamide A and B in different species of ARR, also can be used for the comprehensive quality control of traditional Chinese medicine, Asari Radix et Rhizoma.

Abstract: Objective　To analyze the epidemic characteristics of hand, foot and mouth disease (HFMD) in Nanping City, Fujian province and to provide the basis for formulating effective prevention and control measures as well as evaluating the efficacy of prevention and treatment. Methods　Descriptive epidemiological method was used to analyze the incidence data of HFMD in Nanping City from 2012 to 2021. Results　A total of 49 231 cases of HFMD were reported in Nanping City from 2012 to 2021. The incidence fluctuated greatly over the 10-year period, ranging from 76.10/100 000 to 308.93/100 000, with an average incidence of 184.99/100 000 per year. The overall incidence and the number of cases showed a fluctuating downward trend over time, but the incidence was high in the next year, and there were statistically significant differences in the incidence rates between different years(χ2=8 169.176, P<0.001). There were significant regional differences in the incidence, the top three average annual incidence rates were: Guanze County (370.76/100 000), Zhenghe County (295.31/100 000) and Wuyishan City (250.31/100 000). There were two peaks of HFMD incidence each year, with the first occurring in May and June and the second occurring in September and October. The incidence rate was higher among males (215.86/100 000) than females (152.93/100 000), and males were more susceptible than females (RR=1.412, 95%CI=1.387-1.438). The cases were mainly aged 0-4 years, accounting for 86.25% (42 461/49 231) of all cases, and the incidence rate gradually decreased with increasing age (χ2trend=570,105.801, P<0.001). The majority of cases (85.22%, 41 953/49 231) occurred in children living in scattered areas, followed by children in kindergartens (12.39%, 6 101/49 231). The etiological results showed a total of 3 476 laboratory-confirmed cases, and the proportion of three (classes) of enterovirus positivity varied each year, with different pathogen compositions showing statistical significance (χ2=584.613, P<0.001). In addition to the years 2015-2017, during which Cox A16 and EV71 were the dominant strains, other years were dominated by other enteroviruses, with EV71 being the main type in severe and fatal cases of HFMD in Nanping City. Conclusion　Nanping City should strengthen health education for children living in the diaspora and in day-care centers, enhance surveillance of epidemics and pathogenology, improve vaccination rates against EV71, focus on the detection and typing of other enteroviruses, and implement effective prevention and control measures for HFMD.
