Pogostemon cablin is a famous southern medicine.As the important raw material for modern medicine and industry,Pogostemon cablin becomes required with a large marketing demand.However,due to the serious continuous cropping obstacles in the growth process of Pogostemon cablin,the aggravation of diseases of Pogostemon cablin and the degradation of its quality arose.This paper outlined the ecological factors such as climate factors,soil factors and topographic factors suitable for the growth of Pogostemon cablin,analyzed the continuous cropping obstacles and diseases arising in the cultivation,reviewed the current ecological planting mode of Pogostemon cablin such as crop rotation,intercropping,relay-cropping and under-forest planting,and also made a comprehensive evaluation of the economic benefits,ecological benefits and social benefits of the ecological planting mode of Pogostemon cablin,aiming to provide a theoretical basis and a reference for the promotion of the ecological planting mode of Pogostemon cablin.

Objective To investigate the dosimetric effects of different calculation grid size(CGS)in helical tomotherapy(HT)planning system on stereotactic body radiation therapy(SBRT)for non-small cell lung cancer(NSCLC).Methods Nine NSCLC patients receiving radiation therapy for the first time at some hospital from March 2019 to December 2022 were selected as the subjects.SBRT planning was carried out through the HT system with three different CGS plans(Fine,Normal,and Coarse)and the same pitch,modulation factor(MF)and optimization conditions,and the target area indexes of the three CGS plans were compared including conformity index(CI),homogeneity index(HI),dosimetric parameters of the organ at risk(OAR),point dose verification pass rate,treatment time,number of monitor units and Sinograms.SPSS 22.0 was used for statistical analysis.Results For target area HI,there weres significant differences between CGS Fine plan and Coarse plan and between CGS Normal plan and Coarse plan(P＜0.05),while no statistical differences were found between CGS Fine plan and Normal plan(P＞0.05).For target area CI,there were significant differences between CGS Fine plan and Coarse plan(P＜0.05),while no statistical differences were found between CGS Fine plan and Normal plan and between CGS Normal plan and Coarse plan(P＞0.05).For OAR dosimetric parameters,CGS Fine plan and Coarse plan had significant differences in heart Dmax and Dmean,esophageal Dmax and Dmean,V5,V20,V30 and Dmean of the whole lung and affected lung,V5 and Dmax of the affected lung and heart V10 and V30(P＜0.05),CGS Normal plan and Coarse plan had obvious differences in esophageal Dmax(P＜0.05),and the remained dosimetric parameters were not statistically significant(P＞0.05).Fine,Normal and Coarse plans had the point dose verifica-tion pass rates being 0.96％,1.50％and 1.77％,respectively.In terms of treatment time and number of monitor units,there were significant differences between Fine plan and Coarse plan(P＜0.05)while no statistical differences were found between Fine and Normal plans and between Normal and Coarse plans(P＞0.05).Sinograms analyses showed Fine plan had evenly distributed segment color gradient,Coarse plan had areas of very dark and very light color gradients and Normal plan was somewhere in between.Conclusion Low CGS has to be used as much as possible to obtain accurate dose distribution during SBRT planning for NSCLC patients,which contributes to the execution of the radiation therapy plan and the prevention of ad-verse effects.[Chinese Medical Equipment Journal,2024,45(2):52-57]

Objective To investigate the radiotherapy dose impacts of different jaw widths on stereotactic body radiotherapy(SBRT)for hepatocellular carcinoma(HCC)with the hilical tomotherapy(HT)planning system.Methods Totally 16 HCC patients who received radiotherapy at some hospital from March 2021 to August 2023 were selected,and the planning was carried out with the same pitch,modulation factors and optimization conditions and the jaw widths being 1.0,2.5 and 5.0 cm.The dosimetric differences due to the jaw widths in planned targets and organs at risk(OAR)were compared,and the planned treatment time,monitor unit,gantry rotations and gantry period were evaluated.SPSS 22.0 was used for statistical analysis.Results Better dosimetric parameters and lower doses to OARs could be got with lower jaw widths.The widened jaw widths resulted in reduced planned treatment time,decreased monitor units and gantry rotations,shortened gantry period while enhanced treatment efficiency.Conclusion A 2.5 cm jaw width for HT planning contributes to improving treatment efficiency during HCC SBRT under the premise of ensured target dose distribution and satisfactory dose to OAR for clinical require-ments.[Chinese Medical Equipment Journal,2024,45(7):51-55]

Objective To study the diagnosis,treatment,and complications of hypophosphatemic rickets(HR)in children,explore effectiveness evaluation indicators for the disease,and understand the pattern in height growth among these patients.Methods A retrospective analysis of the initial clinical data and five-year follow-up data of 85 children with HR treated at Children's Hospital of Nanjing Medical University from January 2008 to December 2022.Results Among the 85 children with HR,there were 46 males(54%)and 39 females(46%).The age at initial diagnosis ranged from 6 months to 13 years and 9 months,with a median age of 2.75 years.The average height standard deviation score was-2.0±1.1.At initial diagnosis,children exhibited reduced blood phosphate levels and elevated alkaline phosphatase(ALP),with 99%(84/85)presenting with lower limb deformities.The positive rate for PHEX gene mutations was 93%(55/59).One year post-treatment,there was a significant reduction in ALP levels and the gap between the lower limbs(P<0.05).The fastest height growth occurred in the first year after treatment,at 8.23 cm/year,with a peak height velocity(PHV)phase lasting about two years during puberty.The height increased by 9-20 cm in male children during the PHV stage and 10-15 cm in female children.Major complications included nephrocalcinosis and hyperparathyroidism.The incidence rate of nephrocalcinosis in the first year after treatment was 55%(22/40),which increased with the duration of the disease(P<0.001);an increased urinary phosphate/creatinine ratio was positively associated with a higher risk of nephrocalcinosis(OR=1.740,P<0.001).The incidence of hyperparathyroidism in the first year after treatment was 64%(27/42).Conclusions For children presenting with lower limb deformities,short stature,and slow growth,early testing for blood levels of phosphate,calcium,and ALP,along with imaging examinations of the lower limbs,can aid in the early diagnosis of HR.Genetic testing may be utilized for definitive confirmation when necessary.ALP combined with improvements in skeletal deformities and annual height growth can serve as indicators of therapeutic effectiveness for HR.Compared to normal children,children with HR demonstrate a lower height increase during the PHV phase,necessitating close follow-up and timely adjustment of treatment plans

Objective:To compare the short-term effect and adverse reaction of venetoclax(VEN)combined with azacitidine(AZA)versus"7+3"regimen in newly diagnosed elder patients with acute myeloid leukemia(AML).Methods:From January 2021 to January 2022,the clinical data of seventy-nine newly diagnosed elder patients with AML at the Second Hospital of Shanxi Medical University and the Shanxi Bethune Hospital were retrospectively analyzed,including VEN+AZA group(41 cases)and"7+3"group(38 cases).The propensity score matching(PSM)method was used to balance confounding factors,then response,overall survival(OS),progression-free survival(PFS)and adverse reactions between the two groups were compared.Results:The ORR of VEN+AZA group and"7+3"group was 68％and 84％,respectively,and the CRc was 64％and 72％,respectively,the differents were not statistically significant(P＞0.05).In the VEN+AZA group,there were 5 non-remission(NR)patients,4 with chromosome 7 abnormality(7q-/-7),and 1 with ETV6 gene mutation.Median followed-up time between the two groups was 8 months and 12 months,respectively,and the 6-months OS was 84％vs 92％(P=0.389),while 6-months PFS was 84％vs 92％(P=0.258).The main hematological adverse reactions in two groups were stage Ⅲ-Ⅳmyelosuppression,and the incidence rate was not statistically different(P＞0.05).The median time of neutrophil recovery in two groups was 27(11-70)d,25(14-61)d(P=0.161),and platelet recovery was 27(11-75)d,25(16-50)d(P=0.270),respectively.The infection rate of VEN+AZA group was lower than that of"7+3"group(56％vs 88％,P=0.012).The rate of lung infections of two groups was 36％and 64％,respectively,the difference was statistically significant(P=0.048).Conclusion:The short-term effect of VEN+AZA group and"7+3"regimens in eldrly AML patients are similar,but the VEN+AZA regimen had a lower incidence of infection.The presence of chromosome 7 abnormality(7q-/-7)may be a poor prognostic factor for elderly AML patients treated with VEN+AZA.

Objective:To investigate the clinical characteristics,coexisting gene mutations and prognosis of acute myeloid leukemia(AML)patients with GATA2 gene mutation.Methods:The clinical data of 370 newly diagnosed AML patients treated in our hospital from January 2008 to January 2021 was analyzed retrospectively,the next-generation sequencing technology was used to detect the mutated genes in those patients.The clinical characteristics of AML patients with GATA2 mutations,the co-mutated genes of GATA2 mutations,and the effect of GATA2 mutation on prognosis were analyzed.Results:A total of 23 patients(6.2％)with GATA2 mutation was detected in 370 AML patients.Compared with GATA2 non-mutation group,patients in GATA2 mutation group were mostly normal karyotypes(P=0.037)and in low-risk cytogenetic stratification(P=0.028).The incidence of CEBPAdm and NRAS in GATA2 mutation group was significantly higher than that in GATA2 non-mutation group(P=0.010,P=0.009).There were no statistically significant differences between the two groups in terms of sex,age,white blood cell count(WBC),platelet count,hemoglobin,bone marrow(BM)blast,induction chemotherapy regimen and CR rate(P＞0.05).Among the 23 patients with GATA2 mutation,the most common co-mutated genes were CEBPAdm,NRAS(both 39.1％),NPM1,FLT3,TET2,WT1(all 17.4％),ASXL1 and IDH1(both 13.0％).Survival analysis showed that there was no statistical difference in 5-year overall survival(OS)and leukemia-free survival(LFS)rates between patients with and without GATA2 mutations in whole cohort(n=370)(P=0.306,P=0.308).Among 306 patients without CEBPAdm,the 5-year OS and LFS rates in GATA2 mutation group showed an increasing trend compared with GATA2 non-mutation group,but the difference was not statistically significant(P=0.092,P=0.056).Among 64 patients with CEBPAdm,there was no statistically significant difference in 5-year OS rate between the GATA2 mutation group and the GATA2 non-mutation group(P=0.104),but the 5-year LFS rate of the GATA2 mutation group was significantly decreased(P=0.047).Among the 23 patients with GATA2 mutation,16 cases received the"3+7"induction regimen,of which 12 cases received allogeneic hematopoietic stem cell transplantation(allo-HSCT);7 cases received the"DCAG"induction regimen,of which 3 cases received allo-HSCT.The CR rate was not statistically different between the"3+7"regimen group and the"DCAG"regimen group(P=1.000).The 5-year OS rate and LFS rate in the transplantation group were significantly higher than the chemotherapy group(P=0.021,P=0.020).Conclusion:GATA2 mutation is more common in AML patients with normal karyotype and low-risk cytogenetic stratification,and it is significantly associated with CEBPAdm and NRAS co-mutations.The prognostic significance of GATA2 is influenced by CEBPAdm.The choice of"3+7"or"DCAG"induction regimen in patients with GATA2 mutation does not affect their CR rate,while the choice of allo-HSCT can significantly improved the prognosis compared with chemotherapy only.

italic>Fusarium oxysporum widely exists in farmland soil and is one of the main pathogenic fungi of root rot, which seriously affects the growth and development of plants and often causes serious losses of cash crops. In order to screen out natural compounds that inhibit the activity of Fusarium oxysporum more economically and efficiently, random forest, support vector machine and artificial neural network based on machine learning algorithms were constructed using the information of known inhibitory compounds in ChEMBL database in this study. And the antibacterial activity of the screened drugs was verified thereafter. The results showed that the prediction accuracy of the three models reached 77.58%, 83.03% and 81.21%, respectively. Based on the inhibition experiment, the best inhibition effect (MIC = 0.312 5 mg·mL^-1) of ononin was verified. The virtual screening method proposed in this study provides ideas for the development and creation of new pesticides derived from natural products, and the screened ononin is expected to be a potential lead compound for the development of novel inhibitors of Fusarium oxysporum.

This study aimed to evaluate the efficacy and safety of various Chinese patent medicines in the treatment of inflammatory response in diabetic nephropathy(DN) based on network Meta-analysis. Randomized controlled trial(RCT) of oral Chinese patent medicines for improving inflammatory response in patients with DN was retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, EMbase, Web of Science, and other databases from database inception to October 2022. All investigators independently screened the literature, extracted data, and evaluated the quality. Stata 16.0 software and RevMan 5.4.1 were used to analyze the data of the literature that met the quality standards. Finally, 53 RCTs were included, involving 6 Chinese patent medicines. The total sample size was 4 891 cases, including 2 449 cases in the test group and 2 442 cases in the control group. The network Meta-analysis showed that(1) in terms of reducing TNF-α, the top 3 optimal interventions according to the surface under the cumulative ranking curve(SUCRA) were Shenshuaining Capsules/Granules/Tablets + conventional western medicine, Jinshuibao Capsules + conventional western medicine, and Niaoduqing Granules + conventional western medicine.(2) In terms of reducing hs-CRP, the top 3 optimal interventions according to SUCRA were Bailing Capsules + conventional western medicine, Tripterygium Glycosides Tablets + conventional western medicine, and Shenshuaining Capsules/Granules/Tablets + conventional western medicine.(3) In terms of reducing IL-6, the top 3 optimal interventions according to SUCRA were Bailing Capsules + conventional western medicine, Tripterygium Glycosides Tablets + conventional western medicine, and Jinshuibao Capsules + conventional western medicine.(4) In terms of reducing UAER, the top 3 optimal interventions according to SUCRA were Shenshuaining Capsules/Granules/Tablets + conventional western medicine, Huangkui Capsules + conventional western medicine, and Jinshuibao Capsules + conventional western medicine.(5) In terms of reducing Scr, the top 3 optimal interventions according to SUCRA were Jinshuibao Capsules + conventional western medicine, Niaoduqing Granules + conventional wes-tern medicine, and Tripterygium Glycosides Tablets + conventional western medicine.(6) In terms of reducing BUN, the first 3 optimal interventions according to SUCRA were Niaoduqing Granules + conventional western medicine, Tripterygium Glycosides Tablets + conventional western medicine, and Huangkui Capsules + conventional western medicine.(7) In terms of improving the clinical total effective rate, the first 3 optimal interventions according to SUCRA were Jinshuibao Capsules + conventional western medicine, Niaoduqing Granu-les + conventional western medicine, and Huangkui Capsules + conventional western medicine. The results showed that the combination of western medicine and Chinese patent medicine could reduce the expression of serum inflammatory factors TNF-α, hs-CRP, and IL-6 and inhibit the inflammatory response. The combination of western medicine and Chinese patent medicine was superior to western medicine alone in reducing Scr, BUN, and UAER, and improving the total effective rate of treatment. Due to the limitation of the quantity and quality of literature included, the above conclusions need to be validated by more high-quality studies.

OBJECTIVE: To investigate the expression of CSF3R mutation in acute myeloid leukemia (AML) and analyze its clinical characteristics and prognosis. METHODS: A retrospective study was conducted in 212 patients with AML who were newly diagnosed in the Second Hospital of Shanxi Medical University from January 1th 2018 to June 30th 2021, including 22 patients with CSF3R mutations as mutation group and 190 patients with CSF3R wild type ［66 cases of them were screened by propensity score matching (PSM), as control group］. The early efficacy and survival between the two groups were compared. RESULTS: The median age of patients in the mutation group was 50(17-73) years old, and the ratio of male to female was 1.2:1 The main types were AML with maturation (11 cases) and acute myelomonocytic leukemia (9 cases). Prognostic stratification was carried out according to the risk stratification system of the European leukemia network in 2017, with 16 cases (72.73%) in the middle and high-risk group. At the initial diagnosis, the median count of white blood cell (WBC) was 44.75(1.30-368.71)×10⁹/L, among which 15 cases (68.18%) were >10×10⁹/L, and the median count of platelet (PLT) was 24(4-55)×10⁹/L. CSF3R T618I (68.18%) was a common mutation site, which had concomitant gene mutations, in which CEBPA mutation was the most common (10 cases, 45.45%), but only existed in CSF3R T618I mutation. The CR/CRi rate was 68.18% and 71.21% in the mutant group and the control group (P >0.05), the median over all survival time was 15 months and 9 months (P >0.05), and the median disease-free survival time was 8 months and 4 months (P >0.05), respectively. CONCLUSION Most AML patients with CSF3R mutation are middle-aged patients, the main types are AML with maturation and acute myelomonocytic leukemia, and most of them have middle and high-risk prognosis. CSF3R mutation may not be an independent prognostic marker for newly diagnosed AML patients.

In the outbreak of COVID-19,triage procedures based on epidemiology were implemented in a local hospital in Changsha to control the transmission of SARS-CoV-2 and avoid healthcare-associated infection.This re-trospective study analyzed the data collected during the triage period and found that COVID-19 patients were en-riched 7 folds into the Section A designated for patients with obvious epidemiological history.On the other side,nearly triple amounts of visits were received at the Section B for patients without obvious epidemiological history.8 COVID-19 cases were spotted out of 247 suspected patients.More than 50％of the suspected patients were submi-tted to multiple rounds of nucleic acid analysis for SARS-CoV-2 infection.Of the 239 patients who were diagnosed as negative of the virus infection,188 were successfully revisited and none was reported as COVID-19 case.Of the 8 COVID-19 patients,3 were confirmed only after multiple rounds of nucleic acid analysis.Besides comorbidities,delayed sharing of epidemiological history added complexity to the diagnosis in practice.The triaging experience and strategy will be helpful for the control of infectious diseases in the future.
