Objective:To investigate the effectiveness and safety of bortezomib combined with conventional chemotherapy regimens for treatment of relapsed/refractory acute B lymphoblastic leukemia (B-ALL).Methods:Twenty patients with relapsed/refractory B-ALL treated with bortezomib combined with chemotherapy in Jiaozuo People's Hospital Affiliated to Xinxiang Medical College, Jiaozuo Coal Industry Group Central Hospital and the Second People's Hospital of Jiaozuo from September 2021 to June 2022 were collected, and their treatment response and prognosis were retrospectively analyzed.Results:The median age of the 20 patients was 49.5 years old (25.0-58.5 years old); 12 were male and 8 were female; 12 were relapsed and 8 were refractory. All patients completed 1 course of bortezomib (1.6 mg/m 2, subcutaneous injection on days 2 and 16) combined with chemotherapy. Before bortezomib treatment, there were 0 case of complete remission (CR), 7 cases of partial remission (PR) and 13 cases of non-remission (NR) in 20 patients, the objective remission rate (ORR) was 35% (7/20), and all were positive for minimal residual disease (MRD). After bortezomib treatment, there were 13 cases of CR, 3 cases of PR and 4 cases of NR, and the ORR was 80% (16/20); the MRD of all patients decreased, among which 13 cases (65%) turned to negative; the differences were statistically significant when comparing CR rate, ORR and MRD negative conversion rate before and after bortezomib treatment ( χ2 values were 65.41, 8.83 and 19.30, all P < 0.05). Four of the 20 patients developed central nervous system infiltration despite bone marrow remission, and one died from post-chemotherapy infection. Myelosuppression occurred in all patients, the incidence of infection was 90% (18/20), and the incidence of digestive system adverse effects was 75% (15/20). Conclusions:Bortezomib combined with conventional chemotherapy regimens is effective and well tolerated in the treatment of relapsed/refractory ALL, and has the potential to enable patients with multi-drug resistant relapse to overcome resistance and to achieve deep remission.

Surgical Safety of Elderly Hospitalized Patients Stratified by Age in General Surgery / 中国医学科学院学报

Objective To compare the surgical safety of elderly hospitalized patients in different age groups undergoing general surgery,and provide references for preoperative evaluation and treatment decision-making.Methods The inpatients ≥ 60 years old in the department of general surgery were selected from a national multi-center survey conducted from January to June in 2015 and from January to June in 2016.The patient characteristics and postoperative outcomes were described,and the risk factors for adverse postoperative outcomes of patients in different age groups were explored.Results The elderly patients (≥75 years old) accounted for 17.33%.The non-elderly patient (< 75 years old) group and the elderly patient (≥75 years old) group had significant differences in the proportions of patients with three or more chronical diseases (13.18% vs.5.36%,P<0.001),emergency surgery (16.64% vs.7.62%,P<0.001),American Society of Anesthesiologists score≥3 (48.68% vs.27.28%,P<0.001),and postoperative return to the intensive care unit(33.64% vs.12.00%,P<0.001).The occurrence of postoperative infectious complications showed no significant difference between the two age groups (7.29% vs.6.40%,P=0.410),while severe complications differed between the two groups (6.51% vs.2.60%,P<0.001).Besides,emergency surgery was a common independent risk factor for the two age groups.Conclusions Advanced age is not a contraindication to surgery of elderly patients.With consideration to patient's physical conditions and available surgical resources,elderly patients can still benefit from surgery.

Predictors and Dynamic Nomogram to Determine the Individual Risk of Malignant Brain Edema After Endovascular Thrombectomy in Acute Ischemic Stroke

Background@#and Purpose This study aimed to construct an optimal dynamic nomogram for predicting malignant brain edema (MBE) in acute ischemic stroke (AIS) patients after endovascular thrombectomy (ET). @*Methods@#We enrolled AIS patients after ET from May 2017 to April 2021. MBE was defined as a midline shift of >5 mm at the septum pellucidum or pineal gland based on follow-up computed tomography within 5 days after ET. Multivariate logistic regression and LASSO (least absolute shrinkage and selection operator) regression were used to construct the nomogram. The area under the receiver operating characteristic curve (AUC) and decisioncurve analysis were used to compare our nomogram with two previous risk models for predicting brain edema after ET. @*Results@#MBE developed in 72 (21.9%) of the 329 eligible patients. Our dynamic web-based nomogram (https://successful.shinyapps.io/DynNomapp/) consisted of five parameters: basal cistern effacement, postoperative National Institutes of Health Stroke Scale (NIHSS) score, brain atrophy, hypoattenuation area, and stroke etiology. The nomogram showed good discrimination ability, with a C-index (Harrell’s concordance index) of 0.925 (95% confidence interval=0.890–0.961), and good calibration (Hosmer-Lemeshow test, p=0.386). All variables had variance inflation factors of 0.7, suggesting no significant collinearity among them. The AUC of our nomogram (0.925) was superior to those of Xiang-liang Chen and colleagues (0.843) and Ming-yang Du and colleagues (0.728). @*Conclusions@#Our web-based dynamic nomogram reliably predicted the risk of MBE in AIS patients after ET, and hence is worthy of further evaluation.

Analysis and suggestions on harvest period standards of plant medicinal materials in 2020 edition of Chinese Pharmacopoeia / 中国中药杂志

The improvement of the harvest period standards is critical in the quality control of Chinese medicinal materials. The present study statistically analyzed the harvest period standards of plant medicinal materials in the 2020 edition of Chinese Pharmacopoeia(Vol.Ⅰ) and put forward the existing problems and suggestions based on herbal records and modern research to provide references for the improvement of the standards. According to the statistical analysis, in 499 types of plant medicinal materials, harvest period standards are recorded under 486 types, accounting for 97.4%, and are lacking in the remaining. Only one medicinal material(Stellariae Radix) is recorded with the standard of the harvest year. The standards of the harvest season and phenological period are recorded under 233 types, accounting for 46.7%. For 237 types, only harvest season is specified, accounting for 47.5%, and for 15 types, only harvest phenological period is specified, accounting for 3.0%. Among 222 types mainly derived from cultivation and 51 types from wild resources and cultivation, only 11 types are recorded with harvest period of cultivated products. Only Stellariae Radix is recorded with the harvest period standards for the wild and cultivated products separately. The harvest period standards of plant medicinal materials with different medicinal parts have certain rules to follow. The main problems about the harvest period standards are discovered. Specifically, no harvest period standards are recorded under 13 types of plant medicinal materials. Almost all perennial cultivated medicinal materials are not recorded with harvest year standard. No phenological period standard is found under 250 types of plant medicinal materials. There is no clear distinction between the harvest period standards of cultivated and wild products. The evidence for harvest period standards of 26 types of plant medicinal materials that can be harvested all year round is insufficient. As a result, it is proposed to strengthen basic research in response to the above-mentioned problems and improve the harvest period standards as soon as possible to ensure the quality of Chinese medicinal materials.

Comparative analysis of three complete chloroplast genomes of Inula genus with phylogenetic analysis of 49 plants from Carduoideae / 药学学报

italic>Inula japonica, Inula hupehensis and Inula linaariifolia are all medicinal plants of Inula L. in the Compositae family, and Inula hupehensis is endemic to China. In order to compare their genomic sequence differences and provide scientific basis for their germplasm conservation and development, we obtained and analyzed the complete chloroplast genomes of these three species. Total DNAs were extracted from fresh leaves and subjected to next-generation DNA sequencing. NOVOPlasty was used to assemble the chloroplast genomes from the sequence reads. CPGAVAS2 was used to annotate the genes and repeats in each genome. Lastly, phylogenomics analysis was conducted using RAxML. The results showed that the total length of the chloroplast genome of Inula japonica, Inula hupehensis and Inula linaariifolia is 150 754, 150 909, and 150 812 bp respectively, each consisting of a large single copy region, a small single copy region and a pair of inverted repeat regions. In addition, the G/C content of all three chloroplast genomes was approximately 37.7% and each encoded 111 unique genes, including 79 protein-coding, 28 tRNA and 4 rRNA genes. Meanwhile, 32, 33, 34 simple repeat sequences, 18, 22, 18 tandem repeat sequences and 33, 37, 38 scattered repeat sequences were identified in three species. Phylogenomic analysis showed that all three species of Inula L. and Pluchea indica were clustered together, with the relationship between Inuleae and Senecioneae closer, suggesting that Inuleae may have originated from the Senecioneae, not the Cardueae. The data in this study not only enriches the chloroplast genome database of Inula L., but also lays the foundation for the future studies of species identification, phylogenetic relationships, evolution history and genetic diversity of Inula species.

Effect of early restrictive fluid resuscitation on inflammatory and immune factors in patients with severe pelvic fracture / 中华创伤杂志(英文版)

Purpose:@#To study the effect of early restrictive fluid resuscitation (EFR) on inflammatory and immune factors in patients with severe pelvic fracture (SPF ).@*Methods:@#A total of 174 SPF patients in the Department of Orthopaedics, the First Affiliated Hospital of Chengdu Medical College from July 2015 to June 2018 were involved in this study and divided into EFR group (n = 87) and control group (n = 87) using the random number table method. Conventional fluid resuscitation (CFR) was performed in control group, and EFR was performed in EFR group. The incidences of acute respiratory distress syndrome (ARDS) and multiple organ dysfunction syndrome (MODS) during rescue, successful rescue rate, blood transfusion volume, fluid input, and resuscitation time were compared between the two groups. The parameters including prothrombin time (PT), hematocrit (HCT), platelet (PLT) and blood lactate (BL) at the 4th hour after fluid resuscitation were recorded. The levels of inflammatory factors (TNF-α, IL-6, CRP) and immune factors (CD3＋, CD4＋, CD8＋, CD4＋/CD8＋) were compared between the two groups before treatment and 7 days after treatment. The revised acute physiologic and chronic health evaluation system and the sequential organ failure assessment scores were adopted for evaluation before treatment and 7 days after treatment.@*Results:@#The incidences of ARDS and MODS during rescue in EFR group were significantly lower than those in control group (p=0.015 and 0.010 respectively), and the successful rescue rate in EFR group was significantly higher than that in control group (p = 0.011). The blood transfusion volume, fluid input, resuscitation time in EFR group were significantly lower than those in control group (p = 0.016, 0.002 and 0.001 respectively). At the 4th hour after fluid resuscitation, PT and BL in EFR group were significantly lower than those in control group (p = 0.021 and 0.003 respectively), while HCT and PLT in EFR group were significantly higher than those in control group (p = 0.016 and 0.021 respectively). On day 7 after treatment, TNF-α, IL-6, CRP and CD8＋ in EFR group were significantly lower than those in control group (p = 0.003, 0.004, 0.007 and 0.003 respectively), while CD3＋, CD4＋ and CD4＋/CD8＋in EFR group were significantly higher than those in control group (p = 0.004, 0.000, 0.007 respectively). On day 7 after treatment, the revised acute physiologic and chronic health evaluation (APACHE) system and the sequential organ failure assessment (SOFA) scores in EFR group were significantly lower than those in control group.@*Conclusion:@#EFR can effectively eliminate inflammatory factors, improve immune function, maintain the stability of blood components, reduce the incidences of ARDS and MODS, and elevate the successful rescue rate in patients with SPF.

Isolation and Identification of Main Flavonoid Glycosides of Dendrobium officinale from Danxia Species and Yunnan Guangnan Species / 中国实验方剂学杂志

Objective: To extract,isolate,purify and identify the structures of the flavonoid glycoside in Dendrobium officinale from two different origin places (Danxia species and Yunnan Guangnan species),and provide experimental reference for confirming the common flavonoid glycoside components in D. officinale. Method: ① 70% ethanol was applied to extract the total flavonoids in leaves of D. officinale from two different species. Organic solvents petroleum ether,acetic ether and water saturated n-butyl alcohol were used in turn to extract the crude extraction. Then AB-8 Macroporous resin,Sephadex LH-20 and ODS chromatographic column were applied to isolate and purify the water saturated n-butyl alcohol extraction fraction. The structures of flavonoid glycoside were identified by studying physicochemical property,applying modern spectroscopy method like HPLC,ESI-MSn,1H-NMR,13 C-NMR,etc. ② HPLC characteristic spectrum technique was used to analyse and compare the common flavonoid glycoside components in Dendrobium officinale from different origin places (Danxia species,Yunnan Guangnan species,Guangxi Tiepilan species and Zhejiang native species). Result: Five flavonoid glycoside compounds were isolated from the crude extractions of the leaves of D. officinale from two different species,and they were identified as rutin,vicenin Ⅱ,viceninⅠ,violanthin and isoviolanthin. The characteristic spectrum of vicenin Ⅱ and viceninⅠwere detected in stems of D. officinale from four different origin places (Danxia species,Yunnan Guangnan species,Guangxi Tiepilan species and Zhejiang native species),and vicenin Ⅱ had a better separation degree in the characteristic spectrum. However,the characteristic spectrum of violanthin and isoviolanthin were more obvious in Yunnan Guangnan species and Guangxi Tiepilan species,while rutin was obvious in the Danxia species. Conclusion: Vicenin Ⅱis the common flavonoid glycosides component in D. officinale from different origin places (Danxia species,Yunnan Guangnan species,Guangxi Tiepilan species and Zhejiang native species),and can be used as the internal reference material for the characteristic spectrum of D. officinale.

Parkinson's disease with paroxysmal breath holding and hypoxemia as the manifestation of dyskinesia: a case report / 中华神经科杂志

Parkinson's drug-induced dyskinesia is a common complication after levodopa treatment,and its clinical manifestations are complex.A case of Parkinson's L-dopa-induced dyskinesia misdiagnosed as epilepsy in our hospital is reported.The patient,a 69-year-old male,was hospitalized on May 2,2018 due to "15 years of retardation,recurrent limb twitching with breathing for more than 6 months,sudden loss of consciousess for 10 minutes".The patient took madopar for a long time and had obvious drug complications.In July 2017,the use of rasagiline improved manifestations slightly.In November 2017,repeated limb twitches began to occur.The onset time ranged from several minutes to one hour,and there was a gradual occurrence of twitching accompanied by obvious breathing.On May 1,2018,the patient was sent to our hospital for emergency treatment after limb twitching again.Due to the long-term history of hormone use,and tranquilizers and antiepileptic drugs were used to control the condition of the patient,the patient was misdiagnosed as epilepsy at first.With the adjustment of drugs and the change of condition,the patient was finally diagnosed as Parkinson's L-dopa-induced dyskinesia.The clinical manifestations of the disease include peak dyskinesia,bipolar dyskinesia and dystonia.The pathogenesis of Parkinson's disease is not completely clear and its clinical manifestations are diverse.However,there are few reports of Parkinson's disease,whose manifestation is loss of consciousness due to paroxysmal breath holding and hypoxemia.Therefore,in order to diagnose epilepsy in patients with Parkinson's disease,the possibility of dyskinesia should be excluded first.Therefore,the rational use of drugs is particularly important in the middle and late period of Parkinson's disease.

Complete chloroplast genome of Allium chinense: comparative genomic and phylogenetic analysis / 药学学报

italic>Allium chinense belongs to the genus Alliums of the lily family. It can be used both as medicine and food. To date, the phylogenetic relationship of Allium species have not be resolved completely. Furthermore, there has been a lack of DNA barcode to distinguish closely related species. In this study, the complete chloroplast genome of A. chinense was obtained using next generation DNA sequencing and bioinformatic analysis, and compared with that from other Allium species. The genome is a circular molecule of 152 525 bp with a typical quadripartite structure. Genome annotation identified a total of 116 genes, including 81 protein-coding genes, 31 tRNA genes, and 4 rRNA genes. Analyses of sequences from six Allium species showed that the most diverse regions are found in the protein coding regions such as ndhA and ycf1 genes, and in the intergenic regions, such as ps16-trnQ, trnT-trnF, ndhF-rpl32, rpl32-trnL and rpl16-rps3. A phylogenetic tree was constructed using 58 protein coding sequences from 53 species. All branches showed strong support with bootstrap scores reaching 66%-100%, except those for the Lilium and Paris. Our results suggest that the completed chloroplast genome could solve the classification problems of these species. Using EcoPrimer software, we identified seven markers from the chloroplast genomes, which can be used to differentiate congeneric species. In summary, we have sequenced the complete chloroplast genome of A. chinense, carried out phylogenetic analysis and identified a series of genus specific DNA barcode sequences. The results have laid the foundation for the systematical determination of the phylogenetic relationship of Allium species and the differentiation of species using the genus specific primers.

Results Compared with before treatment, the scores of FMA, MBI, NIHSS and VAS improved in both groups (P<0.05); the scores of FMA, NIHSS and VAS in the TCM group were significantly improved than the control group after treatment (P<0.05). Compared with before treatment, the levels of BMD, bone metabolic index were improved in both groups (P<0.05). The levels of BMD, BGP, BALP in the TCM group were better than the control group (P<0.05). There was no abnormality in blood routine, liver and kidney function in the 2 groups after treatment, and no obvious adverse reactions were observed. Conclusion Yishen Huoxue Decoction combined with PEMFs can enhance the motor function, improve the neurological deficit symptoms and decrease the pain in hemiplegia patients with OP, and the bone metabolism.
