RESUMO

BACKGROUND: Lagerstroemia indica is a widely cultivated ornamental woody shrub/tree of the family Lythraceae that is used as a traditional medicinal plant in East Asia and Egypt. However, unlike other ornamental woody plants, its genome is not well-investigated, which hindered the discovery of the key genes that regulate important traits and the synthesis of bioactive compounds. RESULTS: In this study, the genomic sequences of L. indica were determined using several next-generation sequencing technologies. Altogether, 324.01 Mb sequences were assembled and 98.21% (318.21 Mb) of them were placed in 24 pseudo-chromosomes. The heterozygosity, repeated sequences, and GC residues occupied 1.65%, 29.17%, and 38.64% of the genome, respectively. In addition, 28,811 protein-coding gene models, 327 miRNAs, 552 tRNAs, 214 rRNAs, and 607 snRNAs were identified. The intra- and interspecies synteny and Ks analysis revealed that L. indica exhibits a hexaploidy. The co-expression profiles of the genes involved in the phenylpropanoid (PA) and flavonoid/anthocyanin (ABGs) pathways with the R2R3 MYB genes (137 members) showed that ten R2R3 MYB genes positively regulate flavonoid/anthocyanin biosynthesis. The colors of flowers with white, purple (PB), and deep purplish pink (DPB) petals were found to be determined by the levels of delphinidin-based (Dp) derivatives. However, the substrate specificities of LiDFR and LiOMT probably resulted in the different compositions of flavonoid/anthocyanin. In L. indica, two LiTTG1s (LiTTG1-1 and LiTTG1-2) were found to be the homologs of AtTTG1 (WD40). LiTTG1-1 was found to repress anthocyanin biosynthesis using the tobacco transient transfection assay. CONCLUSIONS: This study showed that the ancestor L. indica experienced genome triplication approximately 38.5 million years ago and that LiTTG1-1 represses anthocyanin biosynthesis. Furthermore, several genes such as LiDFR, LiOMTs, and R2R3 LiMYBs are related to anthocyanin biosynthesis. Further studies are required to clarify the mechanisms and alleles responsible for flower color development.

RESUMO

Objective: Clinical characteristics and outcome in COVID-19 with brucellosis patients has not been well demonstrated, we tried to analyze clinical outcome in local and literature COVID-19 cases with brucellosis before and after recovery. Methods: We retrospectively collected hospitalization data of comorbid patients and prospectively followed up after discharge in Heilongjiang Infectious Disease Hospital from January 15, 2020 to April 29, 2022. Demographics, epidemiological, clinical symptoms, radiological and laboratory data, treatment medicines and outcomes, and follow up were analyzed, and findings of a systematic review were demonstrated. Results: A total of four COVID-19 with brucellosis patients were included. One patient had active brucellosis before covid and 3 patients had nonactive brucellosis before brucellosis. The median age was 54.5 years, and all were males (100.0%). Two cases (50.0%) were moderate, and one was mild and asymptomatic, respectively. Three cases (75.0%) had at least one comorbidity (brucellosis excluded). All 4 patients were found in COVID-19 nucleic acid screening. Case C and D had only headache and fever on admission, respectively. Four cases were treated with Traditional Chinese medicine, western medicines for three cases, no adverse reaction occurred during hospitalization. All patients were cured and discharged. Moreover, one case (25.0%) had still active brucellosis without re-positive COVID-19, and other three cases (75.0%) have no symptoms of discomfort except one case fell fatigue and anxious during the follow-up period after recovery. Conducting the literature review, two similar cases have been reported in two case reports, and were both recovered, whereas, no data of follow up after recovery. Conclusion: These cases indicate that COVID-19 patients with brucellosis had favorable outcome before and after recovery. More clinical studies should be conducted to confirm our findings.

RESUMO

In this study, fluoride (F) was stabilized and soluble components, namely phosphate (P), K, Ca, Cr, Mn, and Pb, were extracted from phosphorus slag (PS) by using aluminum sulfate (AS) synergistic electrokinetic. PHREEQC simulation was used to determine the occurrence form of each ion in the PS. The mechanisms by which various electrokinetic treatment methods affected conductivity and pH distribution were carefully investigated. Electrokinetic treatment increased P concentration of the anode chamber from 22.7 mg/L to 63.39 mg/L, whereas K concentration increased from 15.26 mg/L to 93.44 mg/L. After AS-enhanced electrokinetic treatments, the concentrations of the different components were as follows: P, 131.66 mg/L; K, 198.2 mg/L; and Ca, 331.3 mg/L. The removal rate of soluble P in PS slices increased to 80.88% by 1.5 V/cm of treatment, and it increased to 94.04% after AS enhancement treatment. For water-soluble F, the removal rate from the PS slices in the anode region was 86.03%, decreasing F concentration in the electrode chamber to 9.57 × 10-3 mg/L. Different extraction efficiencies and stability levels of each component in the PS were regulated at various electrode regions by using different processes such as electromigration, electro-osmotic flow, flocculation, and precipitation. Good results can be obtained if fluoride is solidified concurrently with the removal or recovery of P, K, Ca, and other elements using 2%-4% AS enhanced electrokinetic treatment. Furthermore, CaSO4·2H2O whiskers were produced in the electrode regions when AS content was 6%. The findings of this study indicated that the AS synergistic electrokinetic method is suitable for stabilizing F and removing heavy metals from PS, thus providing a promising technology for recycling valuable components such as P, K, Ca, and Sr and for the simultaneous production of CaSO4·2H2O whiskers. This study provides insights for developing novel technologies for the clean treatment and high-value utilization of PS.

RESUMO

On March 19, 2020, the governor of California issued a statewide stay-at-home order to contain the spread of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19).* The order reduced accessibility to and patient attendance at outpatient medical visits,† including preventive services such as cervical cancer screening. In-person clinic visits increased when California reopened essential businesses on June 12, 2020.§ Electronic medical records of approximately 1.5 million women served by Kaiser Permanente Southern California (KPSC), a large integrated health care system, were examined to assess cervical cancer screening rates before, during, and after the stay-at-home order. KPSC policy is to screen women aged 21-29 years every 3 years with cervical cytology alone (Papanicolaou [Pap] test); those aged 30-65 years were screened every 5 years with human papillomavirus (HPV) testing and cytology (cotesting) through July 15, 2020, and after July 15, 2020, with HPV testing alone, consistent with the latest recommendations from U.S. Preventive Services Task Force.¶ Compared with the 2019 baseline, cervical cancer screening rates decreased substantially during the stay-at-home order. Among women aged 21-29 years, cervical cytology screening rates per 100 person-months declined 78%. Among women aged 30-65 years, HPV test screening rates per 100 person-months decreased 82%. After the stay-at-home order was lifted, screening rates returned to near baseline, which might have been aided by aspects of KPSC's integrated, organized screening program (e.g., reminder systems and tracking persons lost to follow-up). As the pandemic continues, groups at higher risk for developing cervical cancers and precancers should be evaluated first. Ensuring that women receive preventive services, including cancer screening and appropriate follow-up in a safe and timely manner, remains important.

RESUMO

OBJECTIVE: To observe the clinical efficacy of transcutaneous acupoint electrical stimulation (TAES) combined intravenous injection and/or Neiguan (P6) injection with droperidol in preventing and treating post-operative nausea and vomiting (PONV) after thyroid tumor surgery. METHODS: Recruited were 120 female patients who underwent selective thyroid tumor surgery were randomly assigned to the control group, the TAES group, the IV group (intravenous injection of droperidol), and the P6 group [Neiguan point (P6) injection of droperidol], respectively, 30 cases in each group. Thirty min before anesthesia induction, 2 mL 0.9% normal saline injection was intravenously injected to those in the control group. Patients in the TAES group received TEAS at bilateral P6 points. 2.5 mg (1 mL) droperidol added in 1 mL 0.9 normal saline was intravenously injected to those in the IV group and injected at bilateral P6 points of those in the P6 group. The occurrence and severity of PONV were observed within 0 - 6 h and within 6 - 24 h after operation in each group. RESULTS: Compared with the control group, the incidence and the severity of PONV within 0 - 6 h and within 6 - 24 h after thyroid surgery were significantly reduced in the three treatment groups (P < 0.05). There was no statistical difference in the incidence or the severity of PONV among the TAES, IV and P6 groups (P > 0.05). CONCLUSIONS: TEAS at P6 could dramatically reduce the occurrence and the severity of PONV after thyroid tumor surgery. Besides, it got equivalent effect to that by intravenous injecting droperidol or by injecting droperidol at P6.

RESUMO

OBJECTIVE: To observe the electroacupuncture (EA) pretreatment at Baihui (GV20) on the concentration of adenosine deaminase (ADA) and adenosine, and to evaluate its effects on the neurologic function score and the infarction volume after middle cerebral artery occlusion (MCAO) ischemia/reperfusion (I/R), thus exploring its mechanisms for relieving the ischemia/reperfusion injury. METHODS: Totally 54 male SD rats were randomly divided into 3 groups, the sham-EA group, the EA group, and the control group, 18 in each group. Rats in the control group were not intervened after anesthesia. Rats in the EA group were needled at Baihui (GV20) for 30 min. Rats in the sham-EA group received the same procedure as those performed in the EA group without electricity connected. The changes of adenosine and ADA contents were detected at 30, 60, and 120 min after EA respectively. The I/R model was established. Totally 48 male SD rats were randomly divided into 6 groups, i.e., the model group (Group A), the EA group (Group B), the EA +8-Cyclopentyl-1,3-dipropylxanthine (DPCPX) group (Group C), the EA + DMSO group (Group D), the Deoxycoformycin (Deo) group (Group E), and the normal saline group (Group F). Rats in Group B, C, and D received EA for 30 min before modeling. Rats in Group C and D were peritoneally injected with DPCPX (1 mg/kg) and DMSO (1 mL/kg) at 30 min before EA. The neurologic function score was evaluated and the infarct volumes were detected after 24-h reperfusion. RESULTS: Compared with the sham-EA group, there was no statistical difference in the contents of the adenosine or ADA in the control group at each time point (P > 0.05). Compared with the control group at the same time point, the content of ADA significantly decreased at 60 min in the EA group [(315.0 +/- 22.9 U/L), P < 0.05], and restored to the normal level at 120 min after EA. The content of adenosine increased in the EA group at 120 min [(20.4 +/- 2.2) ng/microL, P < 0.05]. Compared with the model group, the neurologic function score decreased (P < 0.05) and the infarct volumes were obviously reduced (P < 0.01) in Group B, D and E. There was no statistical difference in the neurologic function score or the infarct volumes in other groups, when compared with the model group (P > 0.05) CONCLUSION: EA at Baihui (GV20) showed protective effects on the cerebral I/R rats, which might be achieved through lowering the ADA concentration and elevating the adenosine content, and further activating adenosine A1 receptor.

RESUMO

This paper reports the results of an extensive survey on the levels of lovastatin in Pu-erh tea samples. The microbial source of lovastatin was assessed by testing the ability of fungi with higher isolation frequency in the Pu-erh tea samples to produce lovastatin on Czapek yeast extract agar (CYA). Lovastatin was not detected in any of the raw Pu-erh tea samples without storage but was found in almost all the ripe Pu-erh tea samples, with lovastatin contents ranging from 20.61 ng/gdw to 226.38 ng/gdw. After five years' storage, the lovastatin levels increased obviously in ripe Pu-erh tea samples and 55% of raw Pu-erh tea samples from 2007 were found to contain lovastatin with concentrations ranging between 28.41 ng/gdw and 228.61 ng/gdw. With increasing storage time, lovastatin concentration in ripe Pu-erh tea, and the occurrence and concentration of lovastatin for raw Pu-erh tea increased significantly. Three genera of fungi: Aspergillus, Penicillium and Trichoderma were often isolated from Pu-erh tea samples. A total of 40 strains from 3 fungal genera were selected to test their ability to produce lovastatin. Only 6 strains, Aspergillus tubingensis, Aspergillus wentii, Aspergillus fumigatus, Penicillium chrysogenum, Trichoderma asperellum and Trichoderma citrinoviride, were able to produce lovastatin reaching concentrations of 9.59 ± 0.42 ng/g CYA, 2.33 ± 0.21 ng/g CYA, 2.77 ± 0.13 ng/g CYA, 3.36 ± 0.69 ng/g CYA, 4.8 ± 0.17 ng/g CYA, and 1.47 ± 0.36 ng/g CYA respectively in Czapek yeast extract agar.

RESUMO

The aim of this study was to evaluate tea polyphenol and purine alkaloid contents of pu-erh tea (Camellia assamica) in a fermentation solid system with Aspergillus niger and Aspergillus fumigatu. In addition, the objective was to find the major intermediate product during fermentation by HPLC-MS(n) analysis. The results showed the change of catechin, ester-catechins and gallic acid by quantitative analysis. In the early stages, the contents of ester-catechins were lightly increased. Then, ester-catechins were gradually degraded to produce catechins and gallic acid. Furthermore, a major metabolic intermediate compound of catechins was observed and elucidated by HPLC-DAD-MS(n) analysis. This study provided a reliable dynamic data description and metabolic pathway of tea polyphenols for postfermented pu-erh tea.

RESUMO

Influence of various disturbance intensities on nitrogen, phosphorus and permanganate index (PI) release of Potamogeton crispus were investigated during the plant soaking in water, and the plant materials were collected in an urban lake of Beijing. Results showed that more rapid release of TP and PI from Potamogeton crispus were caused by disturbance, NH4(+) -N and TN in water were significantly increased (ANOVA, p < 0.05) under the condition of high disturbance (120 r/min) for 240 h. However, PI and TP were significantly decreased (ANOVA, p < 0.05) after 240 h disturbance in all treatments. When the release equilibrium of 2.13 g dry mass Potamogeton crispus in one liter of water was reached, the PI, TN, and TP released from unit mass Potamogeton crispus were 35, 5.1 and 4.1 mg x g(-1), respectively. The release ratio of TP from Potamogeton crispus was the highest, while the release ratio of PI was the lowest. The simulated experiment results showed that the highest pollution load to water released from Potamogeton crispus was the TP among the three nutrients. Phosphorus is one of the key factors which causing water eutrophication in lake, thus after submerged plants declining in lake, the field research of phosphorus release and migration from submerged plants into water is the focus of future research work.

RESUMO

OBJECTIVE: To study the protective mechanism of Dusuqing Granule, a compound Chinese herbal medicine, on the senile multiple organ injury caused by bacterial pneumonia by observing the expression changes of molecules related to toll-like receptor 4 (TLR4) signaling. METHODS: A total of 55 male Sprague-Dawley aged rats were divided into control group, untreated group, Dusuqing group and lomefloxacin group. There were 25 rats in the untreated group and 10 rats in each of the other three groups. Multiple organ injury in a rat model of pneumonia was induced by injection of Klebsiella pneumoniae through tracheal intubation. By means of immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR), examinations were made on mRNA expressions of lipopolysaccharide-binding protein (LBP), CD14, TLR4 and interleukin-1 receptor-associated kinase-1 (IRAK-1) in the tissues of the lung, heart and small intestine, and also on the protein expressions of TLR4, tumor necrosis factor receptor-associated factor 6 (TRAF6) and nuclear factor-κB (NF-κB). RESULTS: Expressions of LBP, CD14, TLR4 and IRAK-1 mRNAs in the tissues of the lung, heart and small intestine in the untreated group were stronger than those in the control group (P<0.01 or Plt;0.05). The protein expressions of TLR4, TRAF6 and NF-κB were increased dramatically in the untreated group as compared with the control group (Plt;0.01 or Plt;0.05). Compared with the untreated group, the expressions of LBP, CD14, TLR4 and IRAK-1 mRNAs in the tissues of the lung, heart and small intestine in the Dusuqing group were weakened significantly (Plt;0.01 or Plt;0.05). Meanwhile, the protein expressions of TLR4, TRAF6 and NF-κB were decreased markedly in the Dusuqing group (Plt;0.01 or Plt;0.05). CONCLUSION: Dusuqing Granule is effective in suppressing toll-like receptor signal transduction activation and reducing the secretion of cytokines and inflammatory mediators, which can further reduce the organ tissue injury. Dusuqing Granule can decrease the levels of TLR signal transduction activation including the targets LBP, CD-14, TLR4, IRAK-1, TRAF6 and NF-κB, which is different from the special inhibitor that acts only on some segments.

RESUMO

OBJECTIVE: To objectively assess the influence of Xiaoliu Baofei Pill (XBP) combined with chemotherapy on quality of life (QOL) of patients with stage III-IV non-small cell lung cancer (NSCLC). METHODS: Forty NSCLC patients were equally randomized into 2 groups, the treated group treated with XBP plus chemotherapy, and the control group treated with chemotherapy alone. Patients' QOL was assessed by Functional Assessment of Cancer Therapy (FACT-L) before and after treatment. RESULTS: The scores of the physical condition in the treated group was relatively stable while it lowered significantly as time went by in the control group, significant difference was shown as compared with before treatment and with that in the treated group at the same time points (P < 0.05); scores of the mood condition, the function conditions and additional concerned condition were improved gradually from the 3rd collection in the treated group, but decreased in the control group, although some improvement of mood and function conditions had revealed temporarily in the early stage of treatment. Comparison between groups showed significant difference (P < 0.05). Besides, no significant change was found in domains of patient-doctor relation and society/family condition in both groups. CONCLUSION: XBP combined with chemotherapy can obviously improve the QOL of advanced NSCLC patients.

RESUMO

OBJECTIVE: To investigate the effects of Zhenqing Capsule (ZQC), a compound traditional Chinese herbal medicine, in treating type 1 diabetic rats with peripheral neuropathy. METHODS: Type 1 diabetes was induced by caudal vein injection of high-dose streptozotocin in 30 male Wistar rats. The thirty diabetic rats were randomly divided into three groups: ZQC-treated group, untreated group and aminoguanidine-treated group. Another group of 10 rats was taken as normal control. After 10-week treatment, the changes of body weight and fasting plasma glucose level were measured, and the serum MDA level and the changes of neurological electrophysiology were analyzed. The samples of sciatic nerve in diabetic rats were taken for morphological observation. RESULTS: The MDA level in type 1 diabetic rats was notably reduced in ZQC-treated group as compared with the untreated group (P<0.01). Compared with the untreated group, ZQC could improve the electrophysiology of sciatic nerve including conduction velocity (P<0.05), latency (P<0.01) and wave amplitude (P<0.05). The nerve myelin staining results showed that segmental demyelination of the nerve fibers in ZQC-treated group was not as serious as that in the untreated group. CONCLUSION: ZQC can obviously ameliorate the neurological electrophysiological function and the pathological changes of peripheral nerve in type 1 diabetic rats through the removal of free radical and resistance of lipid peroxidation.

RESUMO

Improve the Medication methods and the efficacy of Chinese medicines with western medicines. Read the according article, compare the advantage and disadvantge of Chinese medicines and western medicines interaction and describe the mechanism of medicines in effect. It shows that using Chinese medicines with western medicines have more disadvantage than adavntage. The clinical Chinese medicines with western medicines should according physical properties and pharmacological effects of drug at first, after taking, general the interval is from 1 hour to 3 hours to prevent medicine has physical reactions or toxicity in stomach, ensure taking medicines safety.

RESUMO

<p><b>OBJECTIVE</b>To investigate the neuro-immune regulatory mechanism of Heart Benefiting recipe (HBR), an effective recipe for treatment of Alzheimer's disease (AD).</p><p><b>METHODS</b>Using immunohistochemical and RT-PCR methods, the neuro-immunological pathological changes in the AD rat model induced by beta-amyloid protein (A beta1-40) via lateral cerebral ventricle injection, including mainly the glial fibrillary acidic protein expression and inflammatory cytokines IL-1beta, IL-6mRNA and beta-amyloid protein precursor (APPmRNA) gene expression were studied. And the effects of HBR on these parameters were observed.</p><p><b>RESULTS</b>Deposition of A beta in cerebral tissue could induce activation of stellate glial cells and abnormal increased levels of inflammatory cytokines (IL-1beta and IL-6mRNA), also the elevation of APPmRNA level. HBR could effectively control the above-mentioned pathological changes.</p><p><b>CONCLUSION</b>HBR could effectively control the inflammation and the A beta immune cascade reaction in brain of AD patients, it is one of the important therapeutic mechanisms of the recipe.</p>

RESUMO

<p><b>OBJECTIVE</b>To establish a convenient, economical and practical analogous oxidative damaged Alzheimer's disease rat model (AD model) for exploring the effect of Tiaoxin Recipe (TXR) on the spatial memory capacity and beta-amyloid protein (A beta) deposition in the model.</p><p><b>METHODS</b>The AD model was established by left ventricular injection of DHF-FeCl3-ADP. Spatial memory and learning capacity of the model rat was observed by Morris water maze method, A beta deposition in its cerebral cortex was observed by immunohistochemistry, and the effect of TXR was analysed.</p><p><b>RESULTS</b>Compared with the normal group, the spatial memory capacity in the model group was obviously decreased, with A beta widely deposited in cortex, immunohistochemical examination showed that the number of A beta positive cells and their mean optic density significantly increased. TXR displayed significantly improving effect on the above-mentioned changes.</p><p><b>CONCLUSION</b>The oxidative damaged model could not only express the clinical characteristics (short-term memory impairment), but also partially reflex the pathological changes (A beta deposition) of AD, is an economical and practical analogous AD model. TXR has the effects of improving spatial memory impairment and lowering A beta deposition in the AD model rats.</p>
