Effect of WeChat-Based Medication Guidance on Symptoms and Serological Parameters in Children with Mycoplasma Pneumoniae.

Objective: The aim of this study was to assess the effect of microsoft-based medication guidance on the level of symptoms and serological indicators in children receiving budesonide nebulisation combined with terbutaline for the treatment of Mycoplasma pneumoniae pneumoniae (MPP). Methods: A total of 109 children with MPP treated in The First Affiliated Hospital of Ningbo University of China between October 2022 and April 2023 were divided into the conventional group (n=54, with medication guidance by telephone follow-up) and the WeChat group (n=55, with medication guidance based on the WeChat platform) using a randomized number table. The time to resolution of symptoms, serological index levels, incidence of adverse drug events, medication adherence scores and satisfaction rate of family guidance were compared between the two groups. Results: The disappearance time of symptoms such as wheezing and cough in the WeChat group was shorter than that in the conventional group (P < .05). After treatment, the C-reactive protein (CRP), interleukin-6 (IL-6) and calcitoninogen (PCT) levels and the incidence of adverse drug events were lower in the WeChat group than in the conventional group (P < .05). After treatment, the levels of forceful spirometry (FVC), 1st-second expiratory volume (FEV1), peak expiratory flow rate (PEF), medication compliance score and family guidance satisfaction rate were higher in the WeChat group than in the conventional group (P < .05). Conclusion: WeChat-based medication guidance can optimize the therapeutic effect of MPP, improve children's medication compliance and satisfaction rate of family guidance, and reduce the occurrence of adverse drug events.

Prevalence and association of early onset severe hyperbilirubinemia in newborn in the East China region: Retrospective medical record analyses.

Research on the prevalence and association of hyperbilirubinemia is controversial because of different cultures, demographics, and clinical conditions. The etiology of hyperbilirubinemia is affected by the environment and other factors in the newborn. The World Health Organization recommended a 1-day hospital stay after uncomplicated delivery, jaundice assessment before discharge, and screening on 3rd and 7th days after birth for hyperbilirubinemia. However, the implementation of these recommendations is difficult in China. The objective of this study was to evaluate the prevalence and association of early onset severe hyperbilirubinemia in newborns in East China. Retrospective medical record analyses for 250 cesarean sections or vaginal deliveries, ≥2 kg body weight, and negative for Hepatitis B surface antigen by birth newborns were performed. A biochemical analyzer, quantitative assay, and quantitative polymerase chain reaction were used to evaluate total serum bilirubin, glucose-6-phosphate dehydrogenase (G6PD) deficiency, and gene variant phenotyping, respectively. A total in 33 (13%) newborns were reported with early onset severe hyperbilirubinemia (according to the American Academy of Pediatrics, total serum bilirubin ≥ 342 µmol/L within 6 hours of birth). All newborns with severe hyperbilirubinemia were hospitalized and underwent phototherapy. The mothers of all newborns had a gestational age ≥ 35 weeks. Hospitalization included artificial feeding, and breastfeeding was rare (P < .0001). ABO incompatibility ("O" blood type for mother and either "A" or "AB" or "B" blood type for newborn, P = .0411), G6PD deficiency (G6PD/6-phosphogluconate dehydrogenase ≤ 1.0 in quantitative assay, P = .0422), Rh incompatibility (the mother's blood type was Rh negative and newborn blood type was Rh positive, P = .0416), fewer genotype rs4149056 frequencies (P = .0452), higher genotype rs2306283 frequencies (P = .0461), and higher genotype rs1805173 frequencies (P = .0471) were independent parameter for early onset severe hyperbilirubinemia of newborns. The prevalence of early onset severe hyperbilirubinemia in Chinese newborns is 13% in the East China region. Blood incompatibility, G6PD deficiency, fewer genotype rs4149056 frequencies, higher genotype rs2306283 frequencies, and higher genotype rs1805173 frequencies were independent predictors of early onset severe hyperbilirubinemia among newborns in the East China region (Level of Evidence: IV; Technical Efficacy: Stage 5).

[Meta-analysis and trial sequential analysis of Chaihuang Granules in treatment of upper respiratory tract infection in children].

This study aimed to evaluate the efficacy and safety of Chaihuang Granules in the treatment of upper respiratory tract infection in children. The databases such as CNKI, Wanfang, VIP, SinoMed, Cochrane Library, PubMed, EMbase, Web of Science, Chinese Clinical Trial Registry, and ClinicalTrials.gov were searched for randomized controlled trial(RCT) of Chaihuang Granules for the treatment of upper respiratory tract infection in children, and supplemented by manual searching of gray literature. Two investigators independently screened the literature, extracted data, and assessed the methodological quality. Meta-analysis was performed using RevMan 5.4 software, trial sequential analysis was conducted using TSA 0.9.5.10 Beta software, and evidence quality evaluation was carried out using GRADE profiler 3.6.1 software. Eighteen RCTs involving 2 459 patients(1 262 in the treatment group and 1 197 in the control group) were included. Meta-analysis showed that compared with conventional therapy alone, Chaihuang Granules significantly improved the total effective rate(RR=1.18, 95%CI[1.15, 1.22], P<0.000 01), reduced the disappearance time of symptoms/signs(MD=-1.39, 95%CI[-1.66,-1.12], P<0.000 01), improved cytokine levels(MD=-2.40, 95%CI[-3.80,-1.00], P=0.000 8), improved humoral immune levels(MD=0.75, 95%CI[0.60, 0.90], P<0.000 01), and reduced the recurrence rate(MD=-2.11, 95%CI[-2.98,-1.25], P<0.000 01). However, the incidence of adverse reactions was not increased(RR=0.94, 95%CI[0.59, 1.49], P=0.78). Subgroup analysis showed that:(1) both Chaihuang Granules used alone(RR=1.19, 95%CI[1.11, 1.27], P<0.000 01) and in combination with other therapies(RR=1.18, 95%CI[1.14, 1.22], P<0.000 01) effectively improved the total effective rate.(2) In terms of symptoms/signs disappearance time, Chaihuang Granules effectively reduced the duration of fever(MD=-1.18, 95%CI[-1.78,-0.58], P=0.000 1), cough with sputum(MD=-1.82, 95%CI[-2.38,-1.25], P<0.000 01), cough(MD=-1.31, 95%CI[-1.89,-0.74], P<0.000 01), sore throat(MD=-1.57, 95%CI[-2.25,-0.89], P<0.000 01), and lung rales(MD=-1.49, 95%CI[-2.06,-0.92], P<0.000 01).(3) Regarding cytokine levels, Chaihuang Gra-nules effectively improved the levels of interleukin(IL)-2(MD=-0.94, 95%CI[-1.16,-0.72], P<0.000 01), IL-6(MD=-4.71, 95%CI[-6.39,-3.03], P<0.000 01), and tumor necrosis factor-α(TNF-α)(MD=-2.07, 95%CI[-2.43,-1.71], P<0.000 01).(4) In terms of cellular immune levels, Chaihuang Granules effectively improved the levels of CD3~+(MD=4.11, 95%CI[1.53, 6.69], P=0.002), CD4~+(MD=4.21, 95%CI[1.69, 6.73], P=0.001), CD8~+(MD=-2.65, 95%CI[-3.93,-1.37], P<0.000 1), and CD4~+/CD8~+(MD=0.25, 95%CI[0.14, 0.37], P<0.000 1).(5) In terms of humoral immune levels, Chaihuang Granules effectively improved the levels of IgA(MD=0.44, 95%CI[0.23, 0.64], P<0.000 1), IgM(MD=0.31, 95%CI[0.15, 0.46], P=0.000 1), and IgG(MD=2.02, 95%CI[1.60, 2.43], P<0.000 01). Trial sequential analysis showed that the cumulative Z-curve of the total effective rate crossed the boundary value, further confirming its clinical efficacy. The GRADE evidence quality evaluation showed that the evidence quality of the above outcome indicators was low or very low, and the recommendation strength was weak. Compared to conventional therapy alone, Chaihuang Granules can effectively improve the total effective rate of treatment, alle-viate symptoms and signs of upper respiratory tract infection in children, improve inflammatory conditions, enhance immune function, and reduce the recurrence rate. Due to the limited quality of the included studies, high-quality RCT is still needed to provide evidence support for the above conclusions.

Combined effects of dietary faba bean water extract and vitamin K3 on growth performance, textural quality, intestinal characteristics, oxidative and immune responses in grass carp.

Faba bean water extract (FBW) and vitamin K3 (VK3) have been demonstrated to improve the muscle textural quality of fish. To better apply these two feed additives in commercial aquaculture setting, four experimental diets (control, commercial feed group; 15% FBW, 15% faba bean water extract group; 2.5% VK3, 2.5% vitamin K3 group; combined group, 15% faba bean water extract + 2.5% vitamin K3 group) were formulated to explore their combined effects of FBW and VK3 on the growth, health status, and muscle textural quality of grass carp. The growth performance, textural quality, intestinal characteristics, and oxidative and immune responses were analyzed on days 40, 80 and 120. The results showed that supplementation with higher doses of FBW and VK3 have no influence on growth-related parameters and immune parameters of grass carp. Notably, compared with the control, fish in the combined group had the highest textural qualities (hardness, chewiness and adhesiveness), followed by those in 15% FBW and 2.5% VK3 groups (P < 0.05). Also, FBW and VK3, to some extent, may lower antioxidative ability of grass carp, as illustrated by lower levels of GSH and CAT in 15% FBW, 2.5% VK3, and combined groups on day 120 (P < 0.05). In addition, enhanced lipase activity was observed in the 15% FBW group. Taken together, the combined supplementation of FBW and VK3 was demonstrated to be a more advanced option than their individual supplementation in a commercial setting owing to the resulting combined effects on both the textural quality and health status of grass carp.

Integrated Nursing and Targeted Functional Training for Cerebral Hemorrhage Recovery.

Objective: This study aimed to investigate the impact of integrating medical nursing with targeted functional training interventions on neurological and limb motor function and self-care ability in patients diagnosed with cerebral hemorrhage. Methods: A retrospective cohort study was conducted, including 100 patients diagnosed with cerebral hemorrhage who received interventions at our hospital between January 2020 and June 2022. The patients were divided into two groups: the research group (50 cases) and the reference group (50 cases), based on different intervention methods. The reference group received targeted functional training intervention, while the research group implemented the integration of medical nursing in addition to the reference group intervention. Differences in the National Institutes of Health Stroke Scale (NIHSS) score, Barthel index, Modified Barthel Index (MBI) score, Glasgow Coma Scale (GCS) score, Edinburgh Speech Scale (ESS) score, Fugl-Meyer score, Ability of Daily Living (ADL) score, and efficacy evaluation were observed and compared between the two groups of patients. Results: After nursing, the Fugl-Meyer score and Barthel index score were significantly higher in both groups compared to before nursing, with the research group showing higher scores than the reference group (P < 0.05). There was no significant difference in limb motor function scores between the two groups before nursing (P > 0.05). After the integrated nursing intervention, the NIHSS and ADL scores of both groups were significantly higher than before nursing, with the research group demonstrating higher scores than the reference group (P < 0.05). Conclusions: Integrating medical nursing with targeted functional training interventions has the potential to significantly improve cognitive function, neurological function, and daily activity engagement in patients with cerebral hemorrhage, thereby enhancing their overall quality of life.

[Meta-analysis and trial sequential analysis of Compound Qinlan Oral Liquid in treatment of acute upper respiratory tract infection].

This study aims to evaluate the efficacy and safety of Compound Qinlan Oral Liquid in the treatment of acute upper respiratory tract infection. Computer-based online searching of CNKI, VIP, SinoMed, Wanfang, ChiCTR, ClinicalTrials.gov, Cochrane Library, PubMed, EMbase, and Web of Science was performed to retrieve the randomized controlled trial(RCT) regarding Compound Qinlan Oral Liquid in the treatment of acute upper respiratory tract infection. In addition, manual searching of gray literature was conducted. After two evaluators independently selected articles, extracted data, and evaluated the quality of methodology included in the studies, Meta-analysis was carried out in RevMan 5.4 and trial sequential analysis(TSA) in TSA 0.9.5.10 Beta. GRADE profiler 3.6.1 was employed to evaluate the evidence quality. A total of 21 RCTs were included in this study, involving 2 651 patients(1 330 patients in the observation group and 1 321 patients in the control group). Meta-analysis showed that compared with conventional western medicine alone, Compound Qinlan Oral liquid improved the total response rate(RR=1.15, 95%CI[1.12, 1.19], P<0.000 01) without increasing the incidence of adverse reactions(RR=0.77, 95%CI[0.47, 1.25], P=0.16). The results of subgroup analysis are described as follows:(1) Compared with conventional western medicine alone, Compound Qinlan Oral Liquid improved the total response rate(RR=1.10, 95%CI[1.05, 1.14], P<0.000 01) and shortened the time to symptom relief(SMD=-0.76, 95%CI[-1.02,-0.51], P<0.000 01). There was no significant difference in the incidence of adverse reactions between the two groups(RR=1.16, 95%CI[0.54, 2.47], P=0.71).(2) Compared with conventional western medicine alone, Compound Qinlan Oral Liquid + conventional western medicine improved the total response rate(RR=1.20, 95%CI[1.15, 1.25], P<0.000 01), decreased traditional Chinese medicine(TCM) syndrome scores(MD=-0.58, 95%CI[-0.75,-0.41], P<0.000 01), shortened the time to symptom relief(SMD=-2.44, 95%CI[-3.09,-1.80], P<0.000 01) and physical sign improvement(MD=-2.57, 95%CI[-4.11,-1.04], P=0.001), lowered the serum levels of inflammatory cytokines(SMD=-2.16, 95%CI[-2.61,-1.70], P<0.000 01), improved respiratory function indicators(SMD=1.48, 95%CI[1.00, 1.96], P<0.000 01), and enhanced the humoral immunity(MD=0.94, 95%CI[0.69, 1.18], P<0.000 01). There was no significant difference in the incidence of adverse reactions between the two groups(RR=0.57, 95%CI[0.29, 1.09], P=0.09). TSA showed that the cumulative Z curve of total response rate crossed the traditional threshold and TSA threshold, further confirming the clinical efficacy of Compound Qinlan Oral Liquid. The GRADE graded the evidence of the above outcome indicators as low or extremely low, and yielded weak recommendation. Compared with conventional western medicine alone, Compound Qinlan Oral Liquid can improve the total effective rate and reduce the time to symptom relief. The combination of Compound Qinlan Oral Liquid and conventional western medicine can improve the total response rate, mitigate the symptoms and improve the physical signs, reduce inflammation, and improve respiratory function and immunity of the patients with acute upper respiratory tract infection. In view of the limited number and quality of the included studies, the above conclusions still require high-quality RCT to provide evidence support.

Effectiveness of agricultural waste in the enhancement of biological denitrification of aquaculture wastewater.

Nitrogen pollution in aquaculture wastewater can pose a significant health and environmental risk if not removed before wastewater is discharged. Biological denitrification uses external carbon sources to remove nitrogen from wastewater; however, these carbon sources are often expensive and require significant energy. In this study, we investigated how six types of agricultural waste can be used as solid carbon sources in biological denitrification. Banana stalk (BS), loofah sponge (LS), sorghum stalk (SS), sweet potato stalk (SPS), watermelon skins (WS) and wheat husk (WH) were studied to determine their capacity to release carbon and improve denitrification efficiency. The results of batch experiments showed that all six agricultural wastes had excellent carbon release capacities, with cumulative chemical oxygen demands of 37.74-535.68 mg/g. During the 168-h reaction, the carbon release process followed the second-order kinetic equation and Ritger-Peppas equation, while carbon release occurred via diffusion. The kinetic equation fitting, scanning electron microscopy, and Fourier transform infrared spectroscopy results showed that LS had the lowest cm and the maximum t1/2 values and only suffered a moderate degree of hydrolysis. It also had the lowest pollutant release rate and cumulative chemical oxygen demand, as well as the most efficient removal of total phosphorous (TP) and total nitrogen (TN). Therefore, we concluded that LS has the lowest potential risk of excess carbon release and capacity for long-lasting and stable carbon release. The WS leachate had the highest TN contents, while the SPS leachate had the highest TP content. In the 181-h denitrification reaction, all six agricultural wastes completely removed nitrate and nitrite; however, SS had the highest denitrification rate, followed by LS, WH, BS, SPS, and WS (2.16, 1.35, 1.35, 1.34, 1.34, and 1.01 mg/(L·h), respectively). The denitrification process followed a zero-order and first-order kinetic equation. These results provide theoretical guidance for effectively selecting agricultural waste as a solid carbon source and improving the denitrification efficiency of aquaculture wastewater treatment.

Impact of microecological agents on water environment restoration and microbial community structures of trench system in a Baiyangdian wetland ecosystem.

AIMS: To evaluate the effects of periodic application of effective microorganism (EM) bacteria and calcium peroxide on water environment restoration of a trench wetland ecosystem and its impact on microbiota in water and sediment. METHODS AND RESULTS: The EM bacteria and calcium peroxide were alternately sprayed into the trench water, and changes in the physicochemical indices of water and sediment, and in microbiota structure were subsequently investigated. Alternately spraying of calcium peroxide and EM bacteria improved the water quality, especially in terms of the dissolved oxygen and transparency of water body, and could further reduce the levels of total nitrogen, total phosphorus and ammonia nitrogen. At the same time, the microbiota structure of the water body was significantly changed by spraying with calcium peroxide and EM bacteria, and the relative abundances of Pseudanabaena, Legionellaceae, Planktothrix, Planctomyces, Phenylobacterium, Rhodobacter, Rhodoferax and Aquirestis were significantly increased. However, there was no significant effect on the physicochemical indexes and microbiota composition of the sediment. CONCLUSIONS: The water quality of the Baiyangdian trench could be significantly restored by regular sprinkling of calcium peroxide and EM bacteria. SIGNIFICANCE AND IMPACT OF STUDY: The results provide an effective technical method for the restoration of trench wetland water.

Vitamin D supplementation for the prevention of vitamin D deficiency after bariatric surgery: a systematic review and meta-analysis.

OBJECTIVE: To evaluate the efficacy of vitamin D supplementation on the prevention of postoperative vitamin D deficiency. METHODS: PubMed, Embase, Web of Science, and Cochrane library were searched. Prospective studies evaluating the effects of vitamin D supplementation in patients who had undergone bariatric surgery were included. Meta-regression was performed to explore heterogeneity, and assess the relationship between dosage of vitamin D supplementation, study design, and prevalence of vitamin D depletion. RESULTS: Twelve studies enrolling 1285 patients met the inclusion criteria, and were included. Vitamin D supplementation was associated with significant improvements in 1-year Vitamin D depletion and 1-year 25-OHD level. A daily supplement of more than 800 IU vitamin D significantly reduced the prevalence of 1-year Vitamin D depletion, but the dosage of less than 800 IU did not. Significant decrease in prevalence of 1-year Vitamin D depletion was observed in randomized controlled trials (RCTs), but not in non-RCTs. For the 1-year 25-OHD level, significant elevation was found in the studies irrespective of the study design and dosage of vitamin D supplementation. Meta-regression showed that there was significant relationship between vitamin D depletion and study design, but not between vitamin D depletion and the dosage of vitamin D supplementation. CONCLUSION: Vitamin D supplementation with a daily dosage of more than 800 IU is effective in preventing postoperative vitamin D deficiency and improving the 25-OHD level. However, the results should be interpreted cautiously since there was significant heterogeneity among the studies.

The effect of different surface materials on runoff quality in permeable pavement systems.

To investigate the effect of different permeable pavement surface materials on the removal of pollutants from urban storm-runoff, six commonly surface materials (porous asphalt, porous concrete, cement brick, ceramic brick, sand base brick, and shale brick) were selected in this study and the research was carried out by column experiments. Except the concentrations of total suspended solids (TSS), chemical oxygen demand (COD), ammonia nitrogen (NH4-N), nitrate nitrogen (NO3-N), total nitrogen (TN), and total phosphorus (TP) in the influent and effluent that were measured, the removal mechanism of pollutants was discussed further. The results indicate that the surface materials influence the removal efficiency of pollutants greatly and have different effects on certain pollutant. Furthermore, the physical interception and adsorption would be the main mechanism for the removal of pollutants from runoff. For example, for all surface materials, the average removal efficiency of TSS is nearly about 90.0% because of physical interception. Due to the amount of iron oxide, the removal efficiency of COD, NO3-N, and TN of shale brick was 88.2, 35.1, and 17.5%, respectively. NH4-N and TN can be easily removed by porous asphalt due to the high content of organic matter. By lacking of useful adsorption sites, all the surface materials had little effect on the removal of TP from runoff. This research could offer useful guidelines for the better design of permeable pavement system and promote the insight into the removal mechanism of pollutants in permeable pavement system. Graphical abstract Different types of materials for the different types of pollutants in the runoff purification capacity were significantly different, overall, shale brick and porous asphalt Shale bricks and porous asphalt have a better purification effect according to the six kinds of materials.

Proteomic signature of muscle fibre hyperplasia in response to faba bean intake in grass carp.

Fish muscle growth is important for the rapidly developing global aquaculture industry, particularly with respect to production and quality. Changes in muscle fibre size are accomplished by altering the balance between protein synthesis and proteolysis. However, our understanding regarding the effects of different protein sources on fish muscle proteins is still limited. Here we report on the proteomic profile of muscle fibre hyperplasia in grass carp fed only with whole faba bean. From the results, a total of 99 significantly changed proteins after muscle hyperplasia increase were identified (p < 0.05, ratio <0.5 or >2). Protein-protein interaction analysis demonstrated the presence of a network containing 56 differentially expressed proteins, and muscle fibre hyperplasia was closely related to a protein-protein network of 12 muscle component proteins. Muscle fibre hyperplasia was also accompanied by decreased abundance in the fatty acid degradation and calcium signalling pathways. In addition, metabolism via the pentose phosphate pathway decreased in grass carp after ingestion of faba bean, leading to haemolysis. These findings could provide a reference for the prevention and treatment of human glucose-6-phosphate dehydrogenase deficiency ("favism").

Microbial succession in biofilms growing on artificial substratum in subtropical freshwater aquaculture ponds.

Biofilms can be used to improve the water quality in aquaculture ponds, and elucidating the process of microbial succession in biofilms would allow the characterization of metabolic processes and permit optimization. In the present study, microbial succession of a biofilm growing on artificial substrata in a subtropical freshwater pond was investigated by high-throughput sequencing. Providing artificial substrata effectively reduced the concentrations of total nitrogen and total phosphorus in the pond. Relatively stable microbiota were formed after approximately 1 week. The dominant phyla in the mature biofilm were Proteobacteria, Bacteroidetes, Firmicutes and Actinobacteria. The relative abundances of denitrifiers and phosphorus-removing bacteria, such as those in Comamonadaceae and Neisseriaceae, were significantly increased. The use of avermectin B1 changed the community structure of the microbiota; the microbiota were more similar to those at Week 0 than to those at Week 3. However, the microbial community structure recovered after approximately 1 week. Our results indicate that using artificial substrata can create a habitat for denitrifiers and phosphorus-removing bacteria, and thereby improve pond water quality. This study provided insight into how the use of artificial substrata could improve water quality and elucidated the environment-biofilm relationship in a subtropical freshwater pond.

[Effects of hormone treatment, light and temperatures on sprouting characteristics of Bupleurum chinense].

Seeds of Bupleurum chinense cultivar, Zhongchai No. 1, were sowed in plastic pots which used the arable layer soil as the nursery bed and putted in the artificial climate incubator at various temperatures (15, 20, 25, 15-25 degrees C) and light (8,12 h) to germinate, respectively. The lower constant temperature (15 degrees ) and the higher constant temperature (25 "C) were not conducive to the sprouting characteristics of B. chinese. While they were able to enhance root activity to some extent; The seeding growth of B. chinese was significantly better in the variable temperature than correspondence in the constant temperature, significantly. The emergence speed, emergence index, vigor index and root activity of Bupleurum were improved under the 12 h of light-time, but the germination rate was not improved. The sprouting of Bupleurum's seeds could be improved to some extent by soaking with hormone, such as gibberellin, cytokinin, salicylic acid. Gibberellin promoted seeds' sprouting and seedings's root activity of Bupleurum, while salicylic acid increased the root activity of seeding. There is a significant influence of light, temperatures and hormone treatment on the germination of Zhongchai No. 1 seeds, and all three are remarkably interacted; It is beneficial to promote seed germination by the temperature (20 + 5) degrees C, lighting (8 h) and gibberellin concentration (10 x 10(-6)).

[Evaluation of Bupleuri Radix resources in Qingchuan based on DTOPSIS and grey related degree].

OBJECTIVE: To analyze the essential oils from flowers, leaves, stems, roots, and fruits of Chaihu (Radix Bupleuri Chinensis). METHODS: We extracted essential oils from different parts of Chaihu (Radix Bupleuri Chinensis) using a steam distillation method. The essential oils were analyzed by gas chromatography-mass spectrometry (GC-MS). Data were collected in full scan mode (m/z 60-600). Volatile components were identified based on their retention indices and by comparing their mass spectra with those in the National Institute of Standards and Technology 2005 database, assisted by tandem mass spectrometry information. The relative content of each constituent was determined by area normalization. RESULTS: We identified 111 components, of which 12 were common to all 5 parts, 30 were found only in roots, 14 were found only in flowers, 6 were found only in leaves, 4 were found only in stems, and 17 were found only in fruits. CONCLUSION: Our results show that the stems, flowers, leaves, and fruits of Chaihu (Radix Bupleuri Chinensis) contain a high concentration of essential oils, and that the exact composition of the essential oils differs among the plant parts. To develop new medicines and make full use of the Chaihu (Radix Bupleuri Chinensis) resource, it is important to characterize the essential oils from different parts of the plant. In future research, it will be important to determine the pharmacological effects of the various components and the essential oil mixtures.
