RESUMEN
Objective:To summarize the clinical manifestations, electrophysiological, muscle magnetic resonance imaging (MRI), pathological, and genetic characteristics of 8 patients with Emery-Dreifuss muscular dystrophy (EDMD) to improve the recognition and diagnosis of EDMD.Methods:Eight patients with EDMD confirmed by gene analysis admitted to Hebei Medical University Third Hospital from 2011 to 2022 were enrolled. The detailed clinical symptoms, neurophysiological examination, electrophysiological changes (electromyography and electrocardiography), skeletal muscle MRI characters, skeletal muscle pathological features and gene mutations were analyzed retrospectively.Results:The age of onset ranged from 2.0 to 6.0 (3.6±1.2) years. All patients had insidious onset and progressive development. Muscle weakness was the first symptom for 7 cases that manifested as difficulty in squatting and walking up stairs. Later, spinal ankylosis and joint contracture occurred. One patient had scoliosis as the first symptoms. Abnormal electrocardiogram was found in 4 cases. The electromyography of all patients showed myogenic damage. Muscle biopsy demonstrated dystrophic features in 1 patient, and other myopathic features, including a variation in muscle fiber size, a marked increase in internal nuclei, and, smaller diameter of typeⅠfibers. Next-generation sequencing result showed that 6/8 cases carried 4 LMNA heterozygous mutations (c.1583C>G, c.1357C>T, c.148C>T, c.1336A>G); 1/8 case carried EMD hemizygous mutation (c.501C>G); 1/8 carried SYNE1 heterozygous mutation (c.4364G>A). Conclusions:EDMD has highly clinical and genetical heterogeneity. The onset age is usually in childhood. The first symptom is characterized by weakness of lower limbs and abnormal walking posture. Electromyography shows myogenic lesion. Skeletal muscle MRI shows selective fat infiltrations. Muscle biopsy pathology lacks characteristic pathological findings. It is difficult to make diagnosis and differential diagnosis by clinical manifestations and auxiliary examination in the early stage of the disease. The second generation sequencing technology can improve the early diagnosis rate of EDMD.

Objective To investigate the dosimetric difference between volume modulated arc therapy(VMAT)and dynamic multi-leaf collimator intensity modulated radiation therapy(dMLC-IMRT)after breast-conserving surgery for left-sided breast cancer so as to optimize the treatment plan for the patient.Methods The clinical data of 15 patients admitted to the radiothe-rapy department of some hospital after breast-conserving surgery for left-sided breast cancer were selected retrospectively.Three groups of plans were designed for each patient,including continue volume modulated arc therapy(cVMAT),tangent volume modulated arc therapy(tVMAT)and dMLC-IMRT plans,and then compared in terms of the dosimetric parameters of the tumor target areas and organs at risk.SPSS 25.0 software was used for statistical analysis.Results The three groups had the dose distribution of the tumor target areas meet clinical requirements,which had significant differences between the values of D2,Dmean,conformity index(CI)and homogeneity index(HI),while the difference between the numbers of monitor units were not statistically significant.The dMLC-IMRT group had higher D2 value while lowerDmeanthan the cVMAT and tVMAT groups;for CI the cVMAT behaved the best in the three groups,followed by the tVMAT group.In the low-dose region,the cVMAT and tVMAT groups had larger illuminated volumes of the affected lung than the dMLC-IMRT group;the tVMAT group had the smallest illuminated volume of heart in the three groups,and the cVMAT group had the illuminated volume of heart slightly higher than that of the dMLC-IMRT group.In the high-dose region,the cVMAT and tVMAT groups had smaller illuminated volumes of the affected lung than the dMLC-IMRT group,and the illuminated volume of the affected lung of the tVMAT group was larger than that of the cVAMT group;the dMLC-IMAT group had the largest illuminated volume of heart in the three groups,and the differences between the tVMAT and cVMAT groups were not statistically significant.Conclusion In the design of intensity-modulated radiotherapy plans after breast-conserving surgery for left-sided breast cancer,VMAT behaves better than dMLC-IMRT in conformability to the tumor target area and protection of heart and lung at risk.[Chinese Medical Equipment Journal,2023,44(9):59-63]
RESUMEN
We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Ubiquitin-proteasome system (UPS) plays an important role in neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). The discovery of UPS activators for anti-neurodegenerative diseases is becoming increasingly important. In this study, we aimed to identify potential UPS activators using the high-throughput screening method with the high-content fluorescence imaging system and validate the neuroprotective effect in the cell models of AD. At first, stable YFP-CL1 HT22 cells were successfully constructed by transfecting the YFP-CL1 plasmid into HT22 cells, together with G418 screening. The degradation activity of the test compounds via UPS was monitored by detecting the YFP fluorescence intensity reflected by the ubiquitin-proteasome degradation signal CL1. By employing the high-content fluorescence imaging system, together with stable YFP-CL1 HT22 cells, the UPS activators were successfully screened from our established TCM library. The representative images were captured and analyzed, and quantification of the YFP fluorescence intensity was performed by flow cytometry. Then, the neuroprotective effect of the UPS activators was investigated in pEGFP-N1-APP (APP), pRK5-EGFP-Tau P301L (Tau P301L), or pRK5-EGFP-Tau (Tau) transiently transfected HT22 cells using fluorescence imaging, flow cytometry, and Western blot. In conclusion, our study established a high-content fluorescence imaging system coupled with stable YFP-CL1 HT22 cells for the high-throughput screening of the UPS activators. Three compounds, namely salvianolic acid A (SAA), salvianolic acid B (SAB), and ellagic acid (EA), were identified to significantly decrease YFP fluorescence intensity, which suggested that these three compounds are UPS activators. The identified UPS activators were demonstrated to clear AD-related proteins, including APP, Tau, and Tau P301L. Therefore, these findings provide a novel insight into the discovery and development of anti-AD drugs.

RESUMEN
Objective To investigate the effects of hot spring baths on blood pressure, resting heart rate, cardiovascular function related indicators and physical signs in population with high-normal blood pressure. Methods Residents of typical hot spring areas in Guizhou Province were included as the subjects. According to the epidemiological survey of the research group and the physical examination results before the intervention, combined with the inclusion and exclusion criteria, a total of 217 people with high normal blood pressure were selected as the observation subjects. The intervention of hot spring baths was carried out for four weeks, once time per day, 5 times per week, for 40-50 minutes each time. After the intervention, the blood pressure, resting heart rate and serum levels of creatine kinase(CK), lactate dehydrogenase(LDH), and α-hydroxybutyrate dehydrogenase(α-HBDH)were detected, and the improvement of cardiovascular related signs(palpitation, dizziness/headache, cough/sputum and night sweats)were clinically examined. SPSS 23.0 software was used for statistical analysis. Results Paired t-test results showed that the systolic blood pressure, diastolic blood pressure and resting heart rate of 217 high normal blood pressure subjects were significantly lower after hot spring baths(P < 0.01). Further analysis revealed that the number of people with high normal blood pressure dropped from 217 to 128 after the hot spring baths. Before the intervention, 95 of the 217 people with high-normal blood pressure had resting heart rates between 80 and 90 beats/min, and 35 of them above 90 beats/min. After the intervention, the resting heart rates of those above people decreased to 68 and 14, respectively. Serum levels of cardiovascular related indicators showed that CK, LDH, and α-HBDH levels in people with high-normal blood pressure decreased to some extent after the intervention, and CK level was significantly lower than that before the intervention(P < 0.05). The results of clinical examination showed that hot spring baths had a significant improvement effect on palpitation, dizziness/headache, cough/expectoration, and night sweats in people with high-normal blood pressure. Conclusion The typical hot spring baths in Guizhou Province can reduce the blood pressure and resting heart rate in population with high-normal blood pressure, and improve the cardiovascular function related indicators and physical signs to a certain extent.
RESUMEN
Objective To explore the effect of typical hot spring bathing of Guizhou Province on dyslipidemia, which could provide scientific basis for clarifying the physiotherapy effect of hot springs. Methods The typical hot spring sites of three main types(hydrothermal hot spring, warm mineral hot spring and metasilicate hot spring)in Guizhou Province were selected as investigation sites. 189 residents with hyperlipidemia near the investigation sites were selected as subjects and were treated with hot spring baths for 4 weeks, once a day, 5 times a week and 40-50 minutes each time. The age and gender distribution of the subjects were obtained by a questionnaire. The levels of TC, TG, LDL-C and HDL-C in serum were measured by automatic biochemical analyzer at baseline and at the end of hot spring baths. The differences of the three kinds of hot spring baths on improvement rate of dyslipidemia, the changes of abnormal blood lipid indexes and their improvement rates were compared. Results After baths of hydrothermal hot springs, warm mineral hot springs and metasilicate hot springs, the improvement rates of abnormally elevated lipids were 15.6%, 40.4% and 47.9%, respectively. The improvement rates of abnormally elevated lipids after baths of warm mineral hot springs and metasilicate hot springs were significantly higher than that after hydrothermal spring baths(all P < 0.05). Compared with before hot spring bathing, the levels of TC, TG, LDL-C and non-HDL-C in serum significantly decreased in all three kinds of hot springs. Moreover, the degree of decrease of TG in serum and the improvement rate of abnormal TG after baths of warm mineral spring and metasilicate hot spring were significantly higher than that after hydrothermal spring baths. The degree of decrease of LDL-C in serum and the improvement rate of abnormal LDL-C after baths of metasilicate hot spring were significantly higher than that after baths of hydrothermal spring and warm mineral spring(all P < 0.05). Conclusion The three types of typical hot spring baths in Guizhou Province can mitigate the elevation of blood lipid. Compared with hydrothermal spring, warm mineral spring and metasilicate hot spring may have better improvement effect on blood lipid elevation due to their more significant improvement effect on abnormal elevation of TG and LDL-C in serum.
RESUMEN
Objective To study the relieving effects of hot spring bath therapy on sleep quality for people with sleep disorders based on data from health bracelets. Methods After health examinations, 311 people with sleep disorders who participated in the bath therapy in five typical hot spring areas in Guizhou Province were selected as the subjects. A four-week hot spring bath therapy was implemented, and the bathing method and the classification of hot springs were the same as the"Overview of study of the physiotherapy efficacy of typical hot springs in Guizhou Province". The daily sleep time at night(minutes), deep sleep ratio(%), light sleep ratio(%)and rapid eye movement ratio(%)for all subjects were collected using the Huawei Honor Band 3 health bracelets. Repeated measures analysis of variance was used to compare the differences in sleep quality indicators of each group at night each week. The effect of three different hot spring bath therapies on the improvement of night sleep quality was evaluated by factor analysis. Results Hot spring bath therapy can increase night sleep time and deep sleep ratio, while reducing light sleep ratio. Compared with the first week, the night sleep time in the following three weeks significantly increased(P < 0.05), especially in the fourth week; the deep sleep ratio during the third and fourth weeks was significantly higher than during the first and second weeks(P < 0.05), but the light sleep ratio was lower than during the first and second weeks(P < 0.05). The rapid eye movement ratio did not change significantly throughout the 4 weeks(P > 0.05). Further classified according to the physiotherapy components of geological hot springs, the results showed that the water temperature type of hot springs can increase night sleep time and reduce light sleep ratio; the warm mineral type of hot springs has a certain regulatory effect on increasing night sleep time, deep sleep ratio and reducing light sleep ratio; the metasilicic acid type of hot springs can improve night sleep quality by increasing night sleep time and deep sleep ratio, while reducing light sleep ratio and rapid eye movement ratio. The factor analysis results suggest that the metasilicic acid type of hot springs is better than the water temperature type and warm mineral type of hot springs in improving night sleep quality. Conclusion Hot spring bath therapy can improve the night sleep quality for people with sleep disorders to varying degrees, and the metasilicic acid type of hot springs is relatively better than other types.

Objective To explore the improvement effect of typical hot spring bathing on sleep and anxiety and its correlation with serum melatonin level in Guizhou province. Methods Five typical characteristic hot springs in Guizhou were selected according to the geological type of hot spring water. A total of 226 residents in these areas were selected for the survey and the self-rating scale of sleep(SRSS)and the self-rating anxiety scale(SAS)were used to measure their scores before and after hot spring bathing, and the correlation between the changes of SRSS and SAS scores and the serum melatonin levels were analyzed. Results The SRSS and SAS scores of the respondents after hot spring bathing were lower than before, and the difference was statistically significant(P < 0.05). Serum melatonin levels after hot spring bathing were significantly higher than before(P < 0.05), and there was a negative correlation between the changes of SRSS and SAS scores and serum melatonin levels(P < 0.05). Conclusion Typical hot springs in Guizhou Province can significantly improve the sleep quality and anxiety state, which are related to the elevation of serum melatonin level.
RESUMEN
Objective To observe the intervention effect of typical hot spring bathing in Guizhou province on joint pain, serum anti-keratin antibody(AKA), anti-perinuclear factor antibody(APF)and anti-cyclic citrullinated peptide antibody(CCP). Methods A total of 160 people with joint pain symptoms from five typical hot spring areas in Guizhou province were selected as the subjects. They were treated with hot spring bathing intervention for 4 weeks, once a day, 5 times a week, 40 to 50 minutes each time. According to the evaluation index of physiotherapy natural mineral water in the Code for Geological Exploration and Evaluation of Natural Warm Mineral Water Resources(GB/T 13727-2016)and geological types, the five typical hot springs were divided into three different types, namely water temperature type hot springs(water temperature > 36 ℃), metasilicate type hot springs(metasilicate > 50 mg/L)and warm mineral spring type hot springs(total dissolved solids > 1 000 mg/L). WHO pain grading standard was used to score the degree of joint pain before and after hot spring bathing intervention. Serum APF, AKA and CCP antibodies were detected by ELISA kit before and after hot spring bathing. Results The joint pain score of the subjects was 2.60±0.60, and the joint pain score of the total population decreased after intervention(0.61±0.57, P < 0.05). Before intervention, the joint pain scores of water temperature type, metasilicic acid type and warm mineral spring type were 2.78±0.96, 1.98±1.15 and 3.31±0.57, respectively. After intervention, the scores of joint pain of the three kinds of hot spring bathing patients all decreased(P < 0.05), and were 0.50±0.65, 0.48±0.74 and 0.85±0.90, respectively. Before intervention, AKA(ng/L)and CCP(μg/mL)antibody levels of the observed subjects were 34.89±16.06 and 107.58±10.40, respectively, which significantly decreased after intervention(both P < 0.05), namely 26.06±10.68 and 102.93±6.01, respectively. AKA(ng/L)was 35.04±20.01 before intervention, but decreased significantly after intervention(26.61±7.54, P < 0.05). AKA(ng/L)and CCP(μg/mL)were 31.09±17.26 and 106.51±10.13 before intervention, respectively. After intervention, the above two antibody indexes significantly decreased(all P < 0.05)to 24.53±13.98 and 98.57±5.68, respectively. Before intervention, the AKA(ng/L), APF(ng/mL)and CCP(μg/mL)antibody levels were 38.40±8.66, 349.46±118.43 and 104.96±9.66, respectively. After intervention, the above three antibody indexes significantly decreased(all P < 0.05). The values were 34.00±7.55, 269.38±127.55 and 101.65±3.04, respectively. Conclusion The typical hot spring bathing intervention in Guizhou province can relieve the symptoms of joint pain, and the three types of hot springs can reduce the levels of AKA, APF and CCP antibodies to different degrees, and the warm mineral spring type of hot spring is better than the other types of hot spring.

Objective To analyze the changes of major and trace elements in urine before and after hot spring bathing, and to explore the effect of hot spring bathing on element metabolism, so as to provide theoretical reference for the physiotherapeutic efficacy of hot spring bathing. Methods The content of Ca, K, Mg, Na, P, S, Sr, Zn, B, Mn, Ni, V, Se, Co, Cr, Cu, Fe, Mo, As, Cd, Hg, Li, Pb and Al in warm mineral springs, metasilicic springs and mineral springs in Guizhou Province was determined by ICP-MS. On the basis of physical examination, 421 people in hot spring areas of Guizhou Province were selected as the subjects. Under the guidance of professionals, the volunteers took a hot spring bath with the whole body immersed for four weeks, once a day, five times a week, for 40-50 minutes each time. Finally, 311 volunteers completed the standard bath required by this study. The content of major elements(Ca, K, Mg, Na, P, and S), essential trace elements(Co, Cr, Cu, Fe, Mo, Se, Sr, and Zn), possibly essential trace elements(B, Mn, Ni, and V)and potentially toxic elements(Al, As, Cd, Hg, Li, and Pb)in urine was analyzed by ICP-MS. Wilcoxon test was used to compare the differences of various elements in urine before and after bathing. Results The water of the warm mineral spring pool mainly contained Mo, Sr, Zn, B, Al, and Pb. The metasilicic acid water mainly contained Cu, V, and As. The water of the mineral spring bubble pool mainly contained Ca, K, Mg, S, Cr, Fe, Se, Mn, Ni, and Li. Compared with before intervention, the content of major elements(Ca, K, Mg, S), essential trace elements(Co, Cr, Cu, Fe, Mo, Se, Zn)and possibly essential trace elements(B, Mn, Ni, V)significantly increased, and the content of potential toxic elements(Al, Li, Pb)significantly decreased after intervention(all P < 0.05). The results showed that the content of P, S, Co, Cr, Mo, Se, Zn, Mn and Ni increased significantly and the content of Hg decreased significantly after metasilicic acid hot spring bathing compared with that before bathing(all P < 0.05). After warm mineral hot spring bathing, the content of Ca, Mg, S and Zn increased significantly, while the content of Al and Pb decreased significantly(all P < 0.05). The content of Mg, S, Co, Cr, Se and Ni increased significantly and the content of Al decreased significantly(all P < 0.05). Conclusion There are many kinds of mineral elements in hot springs in Guizhou Province. After hot spring bathing, the essential trace elements and possible essential trace elements in human body increased, and the potential toxic elements decreased, but there was no gender difference.
RESUMEN
Objective To understand the influence of hot spring bathing intervention on population's antioxidation functions. Methods Three typical types of hot spring(metasilicic acid type, warm mineral type and temperature type)in Guizhou Province were selected for investigation. According to the inclusion-exclusion criteria, questionnaires and physical examinations results, 421 individuals were selected as observation subjects for hot spring bathing intervention, of which 311 subjects completed 40 to 50 minutes of intervention once a day, 5 days a week, and for 4 weeks. Two physical examinations before and after the intervention were conducted for the 311 subjects. The fasting venous blood samples on the mornings of two physical examinations were collected and the serum was separated. Levels of serum oxidative stress-related parameters including total superoxide dismutase(T-SOD), copper zinc superoxide dismutase(Cu-Zn SOD), glutathione sulfur transferases(GSTs)glutathione peroxidase(GSH-px), sulfhydryl(-SH)and malondialdehyde(MDA)were measured by enzymatical methods. Results The overall comparison showed that compared with before the bathing intervention, the levels of antioxidant enzymes including T-SOD, Cu-Zn SOD, GSTs and GSH-px significantly increased in serum after the intervention(all P < 0.05). There was an increasing trend of serum -SH level after the intervention, but with no statistical differences were seen(P > 0.05). MDA, a product of lipid peroxidation, significantly decreased in serum after the intervention(P < 0.05). The results of classified comparison showed that the effects of different hot spring types on antioxidant enzymes were different. Metasilicic acid type significantly increased the activities of GSTs and GSH-px in serum(all P < 0.05), warm mineral type significantly increased the activities of T-SOD and Cu-Zn SOD in serum(all P < 0.05), and temperature type significantly increased the activities of T-SOD, Cu-Zn SOD and GSTs in serum(all P < 0.05). There were increasing trends of serum -SH levels after bathing intervention of all three hot spring types, but no statistical differences were seen(all P > 0.05). The serum MDA levels decreased significantly after bathing intervention of all three types of hot springs(all P < 0.05). Conclusion Overall, bathing intervention of hot springs can improve the activities of antioxidant enzymes and reduce lipid peroxidation products in population. The results of oxidative stress parameters are slightly different in different types of hot springs. The subjects mainly show the elevation of glutathione related enzyme(GSTs and GSH-px)activities after intervention of metasilicic acid type, the elevation of superoxide dismutase(SOD)activities after intervention of warm mineral type and temperature type, and the decline of lipid peroxidation levels after intervention of all three types. It suggests that hot spring bathing may have certain effects on improving the body's antioxidation functions.
RESUMEN
To study the biopharmaceutics characteristics of paris saponin VII (PSVII). The solubility of PSVII was evaluated by measurement of the equilibrium solubility in different solvents and media. The permeability of PSVII was evaluated by measuring the oil/water partition coefficient (lgP) and determining the apparent permeability coefficient (PC) on a mono-layer Caco-2 cell model. The effects of p-glycoprotein and multidrug resistance related protein 2 on PSVII transport in mono-layer Caco-2 cell model were further investigated. Finally, the small intestinal absorption of PSVII was investigated in rat. In solvents of different pH, the equilibrium solubility of PSVII was quite low, and the dose number of PSVII was larger than 1. The lgP of PSVII was less than 0. The apparent permeability coefficient [PC] of PSVII in mono-layer Caco-2 cell model was less than 14.96 × 10 cm·s, and the efflux ratio of PSVII in mono-layer Caco-2 cell model was less than 1. The transport rate of PSVII in mono-layer Caco-2 cell model was not affected by the inhibitors of p-glycoprotein and multidrug resistance related protein 2. After oral administration, PSVII could be detected in rat intestinal contents, but could not be detected in the small intestinal mucosa. PSVII showed low solubility and permeability, which would result in low oral bioavailability in clinic. PSVII belonged to Class IV compound in biopharmaceutics classification system.
RESUMEN
To analyze the medication regularity of traditional Chinese medicine(TCM) prescriptions for gastropyretic excessiveness diabetes recorded in Chinese Medicine Prescriptions Dictionary. A total of 103 eligible prescriptions were input into the system platform, and the Apriori algorithm was used to analyze their medication regularity. The 103 prescriptions for gastropyretic excessiveness diabetes were selected from the system, and 29 herb medicines were found with frequency of usage more than 8. Totally 33 commonly used herbal pairs(support degree≥10), twenty-three 3-herb core combinations(support degree≥8, confidence values≥0.5), and twenty-one 4-herb core combinations(confidence values≥0.5) were discovered after the medication regularity analysis by Apriori algorithm. The herbal medicine combinations with the highest correlation degree were discovered after the association rule analysis on the 103 prescriptions(support degree≥10, confidence values≥0.5). The four properties, five tastes, channel distributions and frequency of dose of the 103 prescriptions were also obtained after the corresponding analysis. According to the analysis and summary of the above data, the combination of Trichosanthis Radix, Anemarrhenae Rhizoma, Coptidis Rhizoma and Ophiopogonis Radix could reflect the medication regularity of TCM prescriptions for gastropyretic excessiveness diabetes to a certain degree, which is of great significance in guiding value in clinic.

@#BACKGROUND: Post-infarct left ventricular free wall rupture (LVFWR) is not always an immediately catastrophic complication. The rupture can be subacute, allowing time for diagnosis and intervention. Accordingly, early recognition of the entity may be lifesaving. METHODS: We present an electrocardiogram (ECG) change pattern in two cases, which was erroneously attributed to ischemia. Two women in their 80s were admitted to our institute after experiencing the sudden onset of chest pain. They were managed as anterior ST-segment elevation myocardial infarction without reperfusion treatment. Unfortunately, they experienced a recurrence of severe chest pain with cardiogenic shock during hospitalisation. The ECG recorded at that time showed a ST-segment re-elevation in infract-related leads. RESULTS: The two cases were regrettably received a misjudgement of reinfarction at first, and one of the patients even was administrated with tirofi ban. Afterwards the diagnosis of subacute LVFWR was made through antemortem echocardiography. CONCLUSION: New ST-segment elevation (STE) in infarct-associated leads, coupled with recurrence of chest pain and new-onset hypotension, may constitute the premonitory signs of a subacute LVFWR.
RESUMEN
This article reported two cases of myopathy type very long-chain acyl coenzyme A dehydrogenase deficiency patients, whose clinical manifestations were mainly repeated rhabdomyolysis. In case 1, with fluctuating muscle weakness and myalgia, pathology of skeletal muscle biopsy showed a small amount of degenerative and necrotic muscle fibers, and some muscle fibers had slightly increased fat components. ACADVL gene complex heterozygous mutation was found by second-generation sequencing. Case 2 showed increased polyacylcarnitine and decreased free carnitine by tandem mass spectrometry. Clinical onset muscle weakness, muscle pain and repeat rhabdomyolysis suggested to consider myopathy type very long-chain acyl coenzyme A dehydrogenase deficiency. Because of no specific performance in lower limb muscle magnetic resonance imaging and skeletal muscle biopsy pathology, the case needed to be differentiated from other metabolic myopathy, and tandem mass spectrometry detection and the second generation sequencing are helpful to diagnosis and differential diagnosis.
RESUMEN
The patients with severe traumatic brain injury(sTBI)have a higher incidence of epilepsy.It's controversial whether prophylactic antiepileptic drugs(AEDs)are needed to prevent epilepsy in sTBI.Patients with sTBI do not need prophylactic AEDs on the basis of analgesic and sedative treatment in the early stage(within 7 days),and prophylactic AEDs are also not needed in late stage.Patients diagnosed with epilepsy need to take AEDs.
RESUMEN
OBJECTIVE: To investigate the diagnosis and clinical treatment of endometrial stromal nodules(ESN).METHODS: The clinical data of 7 cases of patients with endometrial stromal nodule in our hospital from 2011 January to2018 January were retrospectively analyzed.RESULTS: The median age of 7 patients was 46 years(29-60 years).The clinical manifestations were irregular menstruation and abdominal pain,and a few were asymptomatic.In 5 cases,no echo area was found in the tumor by color Doppler ultrasound,and in 2 cases,the boundary of the tumor was not clear and the blood flow signal was found in the tumor.Four patients underwent MRI and all had high signal on DWI,3 patients showed T2 WI high signal,and 1 patient had slightly lower T2 WI signal.All patients underwent total hysterectomy and were followed up to February 2018,with an average follow-up time of 30 months(1-96 months).No recurrence or malignant change was found in 7 patients.CONCLUSION:s ESN is a benign tumor.DWI shows obvious high signal and clear boundary in MRI,and Doppler ultrasound shows low echo mass in uterus with no echo area or abnormal blood flow signal.Curettage and biopsy under hysteroscopy are helpful for diagnosis.Patients of childbearing age can choose simple tumor resection and should be followed up closely after operation.For postmenopausal women or those with no desire children,hysterectomy and postoperative routine physical examination are recommended.
RESUMEN
Objective :To explore therapeutic effect of single Chinese medicine Bidens pilosa grain on hyperlipidemia and its influence on serum levels of matrix metalloproteinase‐9 (MMP‐9) and tissue inhibitor of metalloproteinases‐1 (TIMP‐1).Methods :A total of 186 hyperlipidemia patients treated in our hospital from Jan 2014 to Jun 2017 were randomly divid‐ed into Bidens pilosa group (n=94 ,received Bidens pilosa grain based on routine treatment ) and Xuezhikang group (n=92 ,received Xuezhikang based on routine treatment ).Both groups were treated for two months .Serum levels of total cho‐lesterol (TC) , triglyceride (TG ) ,low density lipoprptein cholesterol (LDL‐ C) , high density lipoprptein cholesterol (HDL‐C) ,MMP‐9 and TIMP‐1 before and after treatment ,and total effective rate were observed and compared between two groups.Results :Compared with before treatment ,after treatment ,there were significant reductions in serum levels of TC ,TG ,LDL‐C and MMP‐9 [ Bidens pilosa group : (24.46 ± 4.92) μg/L vs.(20.53 ± 2.69) μg/L ,Xuezhikang group :(23.40 ± 2.57) μg/L vs.(19.98 ± 2.02) μg/L] ,and significant rise in serum levels of HDL‐C [ Bidens pilosa group :(1.28 ± 0.45) mmol/L vs.(1.54 ± 0.52) mmol/L , Xuezhikang group : (1.28 ± 0.45) mmol/L vs.(1.55 ± 0.52) mmol/L] and TIMP‐1 [ Bidens pilosa group : (4.67 ± 1.26) μg/L vs.(6.02 ± 2.24) μg/L ,Xuezhikang group :(4.63 ± 1.30) μg/L vs.(6.01 ± 2.31) μg/L] in two groups , P=0.001 all.After treatment ,there were no significant difference in serum levels of TC ,TG ,LDL‐C ,HDL‐C ,MMP‐9 and TIMP‐1 and total effective rate between two groups , P>0.05 all.Conclusion :Bidens pilosa can significantly improve serum lipid level ,reduce serum level of MMP‐9 and increase serum level of TIMP‐1 in hyperlipidemia patients .It's no significant difference compared with Xuezhikang .
