ABSTRACT

Glechomae Herba, the dried aerial part of Glechoma longituba(Labiatae), has the effects of promoting urination, draining dampness, and relieving stranguria. It has received wide attention in recent years owing to the satisfactory efficacy on lithiasis. Amid the in-depth chemical and pharmacological research, it has been found that Glechomae Herba has antibacterial, anti-inflammatory, antioxidant, antithrombotic, hepatoprotective, cholagogic, antitumor, hypoglycemic, and lipid-lowering effects. The main chemical constituents are volatile oils, flavonoids, terpenoids, phenylpropanoids, and organic acids. This paper summarized the chemical constituents and pharmacological effects of Glechomae Herba. Based on genetic relationship of plants, the characteristics, efficacy, and pharmacokinetics of the chemical constituents, and the potential of these constituents as quality markers(Q-markers), it was summed up that ursolic acid, caffeic acid, rosmarinic acid, luteolin-7-O-diglucuronide, apigenin, apigenin-7-O-diglucuronide, apigetrin, and glechone can be the candidate Q-markers of Glechomae Herba.

ABSTRACT

Sophorae Flavescentis Radix is the dried root of Sophora flavescens Ait. and Sophorae Tonkinensis Radix et Rhizoma is the dried root and rhizome of Sophora tonkinensis Gagnep. The two drugs are both from the same genus Sophora, having similar and different compositions and efficacies, however, their differences are not fully demonstrated in current standard. In this study, the high-performance thin-layer chromatography with multi-dimensional and multi-level features combined with electric spray mass spectrometry (HPTLC-ESI-MS) was used to discover and identify the characteristic zones in extracts of Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma, after optimizing the preparation method of the test solution and chromatographic parameters. As a result, 17 main characteristic zones were found on HPTLC chromatograms of Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma, among them, besides 3 known chemicals, another 12 unknown components were identified by HPTLC-ESI-MS, they are 1 alkaloid and 11 flavonoids. The identification results were verified by the reference standards partially and nuclear magnetic resonance spectra after guided-isolation. Finally, a unified HPTLC specific identification method with different markers was established to identify Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma simultaneously. Thanks to abundant chemical information provided when using diverse polarity mobile phases and derivatization reagents, the HPTLC technology offers a convenient strategy for discovery, quality evaluation, and identification of target chemicals when connecting with mass spectrometry.

ABSTRACT

OBJECTIVE@#To investigate the clinical value of analgesia and sedation under bispectral index (BIS) monitoring combined with hydraulic coupled intracranial pressure (ICP) monitoring in severe craniocerebral injury (sTBI).@*METHODS@#(1) A prospective self-controlled parallel control study was conducted. A total of 32 patients with sTBI after craniotomy admitted to the intensive care unit (ICU) of the First People's Hospital of Huzhou from December 2020 to July 2021 were selected as the research objects. ICP was monitored by Codman monitoring system and hydraulically coupled monitoring system, and the difference and correlation between them were compared. (2) A prospective randomized controlled study was conducted. A total of 108 sTBI patients admitted to the ICU of the First People's Hospital of Huzhou from August 2021 to August 2022 were selected patients were divided into 3 groups according to the random number table method. All patients were given routine treatment after brain surgery. On this basis, the ICP values of the patients in group A (35 cases) were monitored by Codman monitoring system, the ICP values of the patients in group B (40 cases) were monitored by hydraulic coupling monitoring system, and the ICP values of the patients in group C (33 cases) were monitored combined with hydraulic coupling monitoring system, and the analgesia and sedation were guided by BIS. The ICP after treatment, cerebrospinal fluid drainage time, ICP monitoring time, ICU stay time, complications and Glasgow outcome score (GOS) at 6 months after surgery were compared among the 3 groups. In addition, patients in group B and group C were further grouped according to the waveforms. If P1 = P2 wave or P2 and P3 wave were low, they were classified as compensatory group. If the round wave or P2 > P1 wave was defined as decompensated group, the GOS scores of the two groups at 6 months after operation were compared.@*RESULTS@#(1) There was no significant difference in ICP values measured by Codman monitoring system and hydraulic coupling monitoring system in the same patient (mmHg: 11.94±1.76 vs. 11.88±1.90, t = 0.150, P = 0.882; 1 mmHg≈0.133 kPa). Blan-altman analysis showed that the 95% consistency limit (95%LoA) of ICP values measured by the two methods was -4.55 to 4.68 mmHg, and all points fell within 95%LoA, indicating that the two methods had a good correlation. (2) There were no significant differences in cerebrospinal fluid drainage time, ICP monitoring time, ICU stay time, and incidence of complications such as intracranial infection, intracranial rebleeding, traumatic hydrocephalus, cerebrospinal fluid leakage, and accidental extubation among the 3 groups of sTBI patients (P > 0.05 or P > 0.017). The ICP value of group C after treatment was significantly lower than that of group A and group B (mmHg: 20.94±2.37 vs. 25.86±3.15, 26.40±3.09, all P < 0.05), the incidence of pulmonary infection (9.1% vs. 45.7%, 42.5%), seizure (3.0% vs. 31.4%, 30.0%), reoperation (3.0% vs. 31.4%, 40.0%), and poor prognosis 6 months after operation (33.3% vs. 65.7%, 65.0%) were significantly lower than those in group A and group B (all P < 0.017). According to the hydraulic coupling waveform, GOS scores of 35 patients in the compensated group were significantly higher than those of 38 patients in the decompensated group 6 months after operation (4.03±1.18 vs. 2.39±1.50, t = 5.153, P < 0.001).@*CONCLUSIONS@#The hydraulic coupled intracranial pressure monitoring system has good accuracy and consistency in measuring ICP value, and it can better display ICP waveform changes than the traditional ICP monitoring method, and has better prediction value for prognosis evaluation, which can replace Codman monitoring to accurately guide clinical work. In addition, analgesia and sedation under BIS monitoring combined with hydraulic coupled ICP monitoring can effectively reduce ICP, reduce the incidence of complications, and improve the prognosis, which has high clinical application value.

ABSTRACT

PURPOSE@#Auditory nerve injury is one of the most common nerve injury complications of skull base fractures. However, there is currently a lack of auxiliary examination methods for its direct diagnosis. The purpose of this study was to find a more efficient and accurate means of diagnosis for auditory nerve injury.@*METHODS@#Through retrospectively analyzing the results of brainstem auditory evoked potential (BAEP) and high-resolution CT (HRCT) in 37 patients with hearing impairment following trauma from January 1, 2018 to July 31, 2020, the role of the two inspection methods in the diagnosis of auditory nerve injury was studied. Inclusion criteria were patient had a clear history of trauma and unilateral hearing impairment after trauma; while exclusion criteria were: (1) severe patient with a Glasgow coma scale score ≤5 because these patients were classified as severe head injury and admitted to the intensive care unit, (2) patient in the subacute stage admitted 72 h after trauma, and (3) patient with prior hearing impairment before trauma. According to Goodman's classification of hearing impairment, the patients were divided into low/medium/severe injury groups. In addition, patients were divided into HRCT-positive and negative groups for further investigation with their BAEP results. The positive rates of BEAP for each group were observed, and the results were analyzed by Chi-square test (p < 0.05, regarded as statistical difference).@*RESULTS@#A total of 37 patients were included, including 21 males and 16 females. All of them were hospitalized patients with GCS score of 6-15 at the time of admission. The BAEP positive rate in the medium and severe injury group was 100%, which was significantly higher than that in the low injury group (27.27%) (p < 0.01). The rate of BEAP positivity was significantly higher in the HRCT-positive group (20/30, 66.7%) than in the HRCT-negative group (1/7, 14.3%) (p < 0.05). Twenty patients (54.05%) were both positive for BEAP and HRCT test, and considered to have auditory nerve damage. Six patients (16.22%) were both negative for BEAP and HRCT test, and 10 patients (27.03%) were BAEP-negative but HRCT-positive: all the 16 patients were considered as non-neurological injury. The rest 1 case (2.70%) was BAEP-positive but HRCT-negative, which we speculate may have auditory nerve concussion.@*CONCLUSION@#By way of BAEP combining with skull base HRCT, we may improve the accuracy of the diagnosis of auditory nerve injury. Such a diagnostic strategy may be beneficial to guiding treatment plans and evaluating prognosis.

ABSTRACT

Saponins and sterones are two main characteristic components in Achyranthis Bidentatae Radix. In order to control the quality of Achyranthis Bidentatae Radix more effectively, a high-performance liquid chromatography (HPLC) method was established by using double external standards calibration method (DESCM) for simultaneous determination of the contents of achyranthoside C, achyranthoside D, β-ecdysterone, 25R-inokosterone and 25S-inokosterone in Achyranthis Bidentatae Radix. Chromatographic separation was achieved on an Agilent Poroshell 120 EC-C18 (150 mm × 4.6 mm, 2.7 µm) using 0.1% phosphoric acid in water and 0.1% phosphoric acid in acetonitrile as mobile phase. The flow rate was 0.8 mL·min-1 and the column temperature was set as 35 ℃, the injection volume was 5 μL and the total analytical time was 30 min. β-Ecdysterone was used as the reference to calculate the relative correction factors (RCF) and relative retention time (RRT) of 25R-inokosterone and 25S-inokosterone, achyranthoside D was used for achyranthoside C. The RCFs of 25R-inokosterone, 25S-inokosterone, and achyranthoside C were 1.116, 1.056, and 0.888 1, respectively. The double external standards calibration method (DESCM) and external standard method (ESM) were used to calculate the contents of five ingredients in Achyranthis Bidentatae Radix samples from different sources and the variation between the results was within acceptable limits (RE ≤ 5%). The results showed that the contents of two saponins and three sterones of Achyranthis Bidentatae Radix were 0.597%-1.916% and 0.044%-0.150% respectively. The total content of saponins was about 10 times that of sterones. In conclusion, the established DESCM allowed simultaneous determination of five ingredients (achyranthoside C, achyranthoside D, β-ecdysterone, 25R-inokosterone, and 25S-inokosterone) in Achyranthis Bidentatae Radix, providing a scientific and feasible overall quality evaluation method for Achyranthis Bidentatae Radix.

ABSTRACT

Qualitative and quantitative methods were used to establish the quality of different medicinal parts of Poria cocos (Poriae Cutis, rubra Poria, white Poria, Poria cum Radix Pini) by using ultra-performance convergence chromatography coupled with photo-diode array and quadrupole time-of-flight mass spectrometry (UPC2-PDA-Q-TOF/MSE). A total of 18 chromatographic peaks were detected from Poria cocos by UPC2-PDA. Principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were used to compare the four medicinal parts. The results showed that there were significant differences in the components of different medicinal parts, and the main triterpenoic acids were poricoic acid A, poricoic acid B, dehydroeburicoic acid, and dehydrotrametenolic acid. When combined with the common active component polyporenic acid C, a method for determination of five triterpenoic acids in different parts of Poria cocos was established. These components could be separated within 15 min, and the amount of methanol was 3.63% of that of HPLC method. Taking the five triterpenoid acids as an index, the content of triterpenoid acids in different parts of Poria cocos from high to low were Poriae Cutis, rubra Poria, white Poria and Poria cum Radix Pini. The method is simple, rapid, and uses minimal solvent. The mobile phase of environment-friendly gas carbon dioxide has unique advantages in reducing environmental pollution, which can provide a basis for the development and standard formulation of Poria cocos and its related products.

ABSTRACT

Objective:To investigate the effect of decompression of optic nerve canal for traumatic optic neuropathy (TON) via lateral supraorbital approach.Methods:A retrospective case series study was performed to analyze clinical data of 23 TON patients admitted to First People's Hospital of Huzhou from December 2013 to June 2019. There were 16 males and 7 females, aged 17-51 years [(34.3±2.2)years]. Degree of visual impairment included count fingers in 4 patients, hand motion in 4, light perception in 9 and loss of light perception in 6. Visual evoked potential examination (VEP) was performed in 15 patients before surgery. The amplitude of P100 completely disappeared in 5 patients, and the amplitude of P100 was lower than the lower limit of normal value and the latency prolonged in 10 patients. The time from injury to operation was 3 h-14 days [(3.3±0.6)days]. All patients underwent decompression of optic nerve canal via supralateral orbital approach, and dural repair was performed simultaneously in 11 patients with dural rupture. Intraoperative fractures and meningeal tears, duration of operation, blood loss, and hospitalization duration were recorded. Combined with the classical visual acuity improvement assessment method and the World Health Organization (WHO) low vision and blind grading standard, visual acuity was compared before operation, at 10 days and 3 months after operation. Glasgow Coma Scale (GCS) was used to evaluate patients' state of consciousness in the course of the disease. Glasgow Outcome Scale (GOS) was used to evaluate the prognosis. Incidence of complications was observed as well.Results:All patients were followed up for 12-16 weeks [(13.5±2.4)weeks]. Intraoperative microscopic exploration revealed that all patients had optic nerve canal fracture, 3 patients had frontal fracture with dural rupture, and 8 patients had ethmoid bone fragment with anterior skull base dural rupture. The duration of operation was 108.5-224.3 minutes [(151.8±30.2)minutes], including (32.5±8.4)minutes for craniotomy. The intraoperative blood loss was 90.5-165.3 ml [(121.3±15.5)ml]. The hospitalization was 14-26 days [(19.7±3.4)days]. The visual acuity of 13 patients (57%) improved and 5 patients (39%) relieved from blindness 10 days after operation, showing significant difference compared with the preoperation ( P<0.05). The visual acuity of 17 patients (74%) improved and 9 patients (39%) relieved from blindness at 3 months after operation. There was significant difference in visual acuity examined between 10 days and 3 months after operation ( P<0.05). Six patients were invalid, and 4 of them had no light perception before operation and the amplitude of VEP examination completely disappeared. All patients had GCS of 15 when left the hospital and GOS of 5 at 3 months after operation. One patient had cerebrospinal fluid rhinorrhea and healed after 7 days of supine position. No secondary hematoma, epilepsy or intracranial infection occurred during follow-up. Conclusion:Optic canal decompression via the lateral supraorbital approach can improve visual acuity in early stage and increase the rate of out of blindness, with low postoperative complications and satisfactory functional recovery, which is worthy of clinical application.

ABSTRACT

Serum samples were tested for IgG antibodies using indirect immunofluorescence assays. We then analyzed associated risk factors. Serum samples were considered positive when reactive at a dilution of more than 1:320. Differences between groups and risk factors associated with exposure were statistically analyzed using Chi-square tests and the generalized linear model. 122 of 1,260 samples (9.68%) were positive for infection. The infection rate ranged from 0% to 30.43% and differed significantly among age groups ( < 0.01); infection rate in the 50-59 years group was significantly higher than that in other age groups. The seroprevalence of varied significantly among sites within the four provinces, and the infection rate of field workers was significantly higher than that of urban workers.

ABSTRACT

BACKGROUND@#Zhibai Dihuang pill (ZBDH), a Chinese herbal formula, has been widely used as an adjunctive therapy to help reduce the patient's steroid dose and maintain low disease activity in systemic lupus erythematosus (SLE).@*OBJECTIVE@#This systematic review evaluates the therapeutic effect of modified ZBDH in reducing steroid use in patients with SLE.@*SEARCH STRATEGY@#A systematic literature search was carried out using seven databases, including PubMed, Embase, Cochrane Central Register of Controlled Trials, Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure, Chinese VIP Information and Wanfang Database, from their inception to June 1st, 2019. The search terms included "systemic lupus erythematosus," "Chinese medicine" and "clinical trial," and their synonyms. Subject headings matching the above terms were also used.@*INCLUSION CRITERIA@#This meta-analysis included randomized controlled trials that evaluated the reduction of steroid dose in patients with SLE. Traditional Chinese medicine (TCM) formulas in experimental group should be prescribed based on ZBDH and used as adjunctive therapy and the comparator should contain steroids.@*DATA EXTRACTION AND ANALYSIS@#Two authors independently conducted database search, study selection, data extraction and quality assessment. The extracted information contained study design, sample size, recruitment mode, diagnostic criteria, inclusion and exclusion criteria, participant characteristics, TCM patterns, TCM formulas and treatment outcomes. The primary outcome was the change of steroid dose. Secondary outcomes included SLE Disease Activity Index (SLEDAI), biomarkers of disease activity and clinical response rate. STATA 15.0 was used to analyze the pooled effects reported as weighted mean difference (WMD) or odds ratio, with a 95% confidence interval (CI).@*RESULTS@#In total, 20 trials involving 1470 SLE patients were included. The pooled result showed that modified ZBDH taken in combination with standard care led to a larger reduction in steroid dose, compared to standard care alone (WMD: 3.79; 95% CI: 2.58-5.01; P < 0.001). Favorable outcomes were also seen in secondary outcome criteria, such as SLEDAI and complement 3. The modified ZBDH treatments were well tolerated without increasing adverse effects.@*CONCLUSION@#The systematic review provided preliminary evidence supporting the use of ZBDH as a co-therapy to aid steroid dose reduction in patients with SLE. However, more rigorous studies should be conducted to validate these findings, and explore the mechanisms of ZBDH's relevant bioactive constituents.

ABSTRACT

BACKGROUND@#Sepsis-3 definitions have been published recently; however, their diagnostic value remains controversial. This study was to assess the accuracy of Sepsis-3 definitions compared to Sepsis-1 definitions by stratifying mortality among adult critically ill patients with suspected infection.@*METHODS@#A multicenter, prospective cohort study was conducted from November 10, 2017 to October 10, 2018, in five Intensive Care Units (ICUs) at four teaching hospitals. Thirty-day mortality was compared across categories for both Sepsis-3 definitions and Sepsis-1 definitions, which were evaluated by logistic regression analysis followed by measurement of the area under the receiver operating characteristic curve (AUROC) for predicting 30-day mortality rates.@*RESULTS@#Of the 749 enrolled patients, 644 (85.9%) were diagnosed with sepsis according to the Sepsis-1 definitions. Among those patients, 362 were diagnosed with septic shock (362/749, 48.3%). However, according to the Sepsis-3 definitions, there were 483 patients with a diagnosis of sepsis (483/749, 64.5%), among whom 299 patients were diagnosed with septic shock (299/749, 39.9%). According to the Sepsis-3 definitions, sepsis (sepsis and septic shock) patients had higher 30-day mortality (41.8%) than sepsis patients according to the Sepsis-1 definitions (31.8%, χ = 5.552, P = 0.020). The AUROC of systemic inflammatory response syndrome (SIRS) and quick sequential organ failure assessment (qSOFA) scores with regard to 30-day mortality rates were 0.609 (0.566-0.652) and 0.694 (0.654-0.733), respectively. However, the AUROC of SOFA scores (0.828 [0.795-0.862]) were significantly higher than that of SIRS or qSOFA scores (P < 0.001).@*CONCLUSION@#In adult critically ill patients with suspected infection, the Sepsis-3 definitions were relatively accurate in stratifying mortality and were superior to the Sepsis-1 definitions.@*TRIAL REGISTRATION@#www.chictr.org.cn (ChiCTR-OOC-17013223).

ABSTRACT

The aim of the present study was to investigate the differences of the pathological changes and cognitive function after bilateral common carotid artery occlusion (BCCAO) between Sprague-Dawley (SD) and Wistar rats. Male SD and Wistar rats were randomly divided into 2 groups, respectively: sham operated (S-sham and W-sham) and operated (S-BCCAO and W-BCCAO) groups. The survival rate and the rate of loss of pupillary light reflex (PLR) were observed on day 1, 3, 7, 14 and 28 after the operation, and the light-dark box, Y-maze and odor recognition tests were performed to detect cognitive function on day 28 after the operation. HE and Luxol fast blue staining were used to observe the pathological changes of gray matter (hippocampus), white matter (optical tract), optic nerve, and retina. The results showed that the survival rate of the W-BCCAO group was 62.5%, and PLR loss rate was 100%; whereas the survival rate of the S-BCCAO group was 100%, and PLR loss rate was 58.3%. In the W-BCCAO group, percentages of time spent and distance traveled in the light box were more than those in the W-sham group, but there was no statistical significance between the S-BCCAO and S-sham groups. In the S-BCCAO group, the percentages of time spent and distance traveled in the III arm (labyrinth arm) of the Y-maze were less than those in the S-sham group, but no statistical significance was found between the W-BCCAO group and W-sham group. In the S-BCCAO group, the discrimination ratio of the odor recognition task was less than that in the S-sham group, but no statistical significance could be seen between the W-BCCAO and W-sham groups. Ischemic injury was observed in the CA1 area of the hippocampus in the S-BCCAO group, but no readily visible damage was observed in the W-BCCAO group. Ischemic injury of the visual beam and optic nerve was observed in both the S-BCCAO and W-BCCAO groups. Compared with the corresponding sham groups, the S-BCCAO and W-BCCAO groups showed serious retinal damage with significant thinner retina. The ganglion cell layer (GCL), inner plexiform layer (IPL), and outer plexiform layer (OPL) were thinner in the S-BCCAO group, but no statistical significances were shown in the other layers. All the layers, except the outer nuclear layer (ONL), were significantly thinner in the W-BCCAO group. The results indicate that there are differences of the pathological changes in the hippocampus and visual conduction pathway after BCCAO between SD and Wistar rats, and the degree of learning and memory injury was also different, which suggests that the vascular dementia model of different rat strains should be selected according to research purpose.

ABSTRACT

Objective To explore the effect of meteorological factors on the incidence of hand foot and mouth disease (HFMD) in Jiangyin City. Methods The distributed lag non-linear model (DLNM) was used to estimate the delayed and cumulative effects of meteorological factors on incidence of HFMD in Jiangyin from 2012 to 2017. Results A total of 21 791 HFMD cases were reported in Jiangyin City during 2012-2017. We observed significant correlations between the daily incidence of HFMD and daily mean temperature (rs=0.402, P<0.001), daily mean pressure (rs=-0.453, P<0.001), and daily mean relative humidity (rs=0.075, P<0.001), respectively. It was indicated that the maximum cumulative effect of daily mean temperature on the incidence of HFMD was 11 ℃ (RR=1.473, 95% CI: 1.99-1.974), and the impact on the onset of HFMD was acute and hightest at the first day (RR=1.090, 95% CI: 1.045-1.136). The cumulative effect on incidence of HFMD was highest at 85% daily relative humidity (RR=1.346, 95% CI: 1.154-1.571), and the impact on HFMD peaked on the 6th day (RR=1.023,95% CI: 1.015-1.031); The maximum cumulative effect of daily mean pressure with the incidence of HFMD was 1010.0 hpa (RR=1.221, 95% CI: 1.020-1.463), but no lag effect was observed at this level. Conclusions Meteorological factors have significant impact on the incidence of HFMD in Jiangyin City, and the effects of temperature and humidity are lagged.

According to the Sepsis-3 definitions, sepsis (sepsis and septic shock) patients had higher 30-day mortality (41.8%) than sepsis patients according to the Sepsis-1 definitions (31.8%, χ2 = 5.552, P = 0.020). The AUROC of systemic inflammatory response syndrome (SIRS) and quick sequential organ failure assessment (qSOFA) scores with regard to 30-day mortality rates were 0.609 (0.566–0.652) and 0.694 (0.654–0.733), respectively. However, the AUROC of SOFA scores (0.828 [0.795–0.862]) were significantly higher than that of SIRS or qSOFA scores (P < 0.001).@*Conclusion:@#In adult critically ill patients with suspected infection, the Sepsis-3 definitions were relatively accurate in stratifying mortality and were superior to the Sepsis-1 definitions.@*Trial Registration:@#www.chictr.org.cn (ChiCTR-OOC-17013223).

ABSTRACT

Background@#Neural respiratory drive (NRD) using diaphragm electromyography through an invasive transesophageal multi-electrode catheter can be used as a feasible clinical physiological parameter in patients with chronic obstructive pulmonary disease (COPD) to provide useful information on the treatment response. However, it remains unknown whether the surface diaphragm electromyogram (EMGdi) could be used to identify the deterioration of clinical symptoms and to predict the necessity of hospitalization in acute exacerbation of COPD (AECOPD) patients.@*Methods@#COPD patients visiting the outpatient department due to acute exacerbation were enrolled in this study. All patients who were subjected to EMGdi and classical parameters such as spirometry parameters, arterial blood gas analysis, COPD assessment test (CAT) score, and the modified early warning score (MEWS) in outpatient department, would be treated effectively in the outpatient or inpatient settings according to the Global Initiative for Chronic Obstructive Lung Disease guideline. When the acute exacerbation of the patients was managed, all the examination above would be repeated.@*Results@#We compared the relationships of admission-to-discharge changes (Δ) in the normalized value of the EMGdi, including the change of the percentage of maximal EMGdi (ΔEMGdi%max) and the change of the ratio of minute ventilation to the percentage of maximal EMGdi (ΔVE/EMGdi%max) with the changes of classical parameters. There was a significant positive association between ΔEMGdi%max and ΔCAT, ΔPaCO, and ΔpH. The change (Δ) of EMGdi%max was negatively correlated with ΔPaO/FiOin the course of the treatment of AECOPD. Compared with the classical parameters including forced expiratory volume in 1 s, MEWS, PaO/FiO, the EMGdi%max (odds ratio 1.143, 95% confidence interval 1.004-1.300) has a higher sensitivity when detecting the early exacerbation and enables to predict the admission of hospital in the whole cohort.@*Conclusions@#The changes of surface EMGdi parameters had a direct correlation with classical measures in the whole cohort of AECOPD. The measurement of NRD by surface EMGdi represents a practical physiological biomarker, which may be helpful in detecting patients who should be hospitalized timely.

ABSTRACT

<p><b>OBJECTIVE</b>Many metals, some of which have been classified as environmental endocrine disruptors, are used extensively in everyday consumer products and are ubiquitous in our living environment. In the present study, we aimed to explore the associations between the prevalence risk of type 2 diabetes and plasma levels of 20 trace elements as well as those of heavy metals in a Han Chinese population.</p><p><b>METHODS</b>We conducted a case-control study to investigate the associations between plasma concentrations of 20 metals and diabetes in Jiangsu province. A total of 122 newly diagnosed cases of type 2 diabetes and 429 matched controls were recruited from community physical examinations in Suzhou City of Jiangsu Province. Plasma metal levels were measured by inductively-coupled plasma mass spectrometry.</p><p><b>RESULTS</b>After adjusting for confounders, plasma vanadium, chromium, manganese, copper, zinc, arsenic, selenium, strontium, palladium, cadmium, cesium, and barium were associated with diabetes risk (P < 0.05). The adjusted OR increased with increasing concentration of vanadium, manganese, copper, zinc, and cesium.</p><p><b>CONCLUSION</b>Many metals, including manganese, copper, zinc, arsenic, selenium, and cadmium in plasma, are associated with the morbidity of diabetes. Monitoring of environmental metal levels and further studies are urgently needed.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the curative efficacy of methotrexate(MTX) combined with rituxan for treating patients with primary central nervous system(CNS) lymphoma.</p><p><b>METHODS</b>One hundred patients with primary CNS lymphoma in our hospital were randomly divided into targeted treatment group(50 cases) and traditional treatment group (50 cases). Targeted treatment group adopted the therapy of high-dose methotrexate combined with rituxan, the traditional treatment group adopted the high-dose methotrexate combined with whole brain radiotherapy. The results of relevant imaging examination, clinical data, imaging, follow-up and the survival time were analysed and compared between these 2 groups.</p><p><b>RESULTS</b>In the targeted therapy group, there were 33 cases in CR, 9 cases were in stable condition, and 5 cases were in partial response, and 3 cases in the progressive stage. In the group of traditional treatment group, 29 cases reached complete remission, 5 cases were in stable condition, 11 cases were in partial response, and 5 cases were in the progressive stage. In the targeted treatment group and traditional treatment group, the median progression-free survival time was 28 and 11 months, respectively.</p><p><b>CONCLUSION</b>The first choice for treatment scheme of PCNSL is high-dose methotrexate chemotherapy combined with whole brain radiotherapy, that showed a certain curative effect, but the adverse reactions are larger, and a big late neuro toxic reaction may occur, while high-dose methotrexate combined PCNSL rituxan treatment shows high curative effect, less adverse reaction and low side effects. This treatment also has a more positive value for the elderly patients with PCNSL.</p>
