Résumé

OBJECTIVE@#This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength.@*METHODS@#We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.@*RESULTS@#In the multimetal linear regression, Cu (β = -2.119), As (β = -1.318), Sr (β = -2.480), Ba (β = 0.781), Fe (β = 1.130) and Mn (β = -0.404) were significantly correlated with grip strength ( P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95% confidence interval: -1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn ( P interactions of 0.003 and 0.018, respectively).@*CONCLUSION@#In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

Résumé

BACKGROUND@#Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is an important occurrence in the natural history of idiopathic pulmonary fibrosis (IPF), associated with high hospitalization rates, high mortality and poor prognosis. At present, there is no effective treatment for AE-IPF. Chinese herbal medicine has some advantages in treating IPF, but its utility in AE-IPF is unclear.@*OBJECTIVE@#The treatment of AE-IPF with Kangxian Huanji Granule (KXHJ), a compound Chinese herbal medicine, lacks an evidence-based justification. This study explores the efficacy and safety of KXHJ in patients with AE-IPF.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS@#We designed a randomized, double-blind, placebo-controlled, exploratory clinical trial. A total of 80 participants diagnosed with AE-IPF were randomly assigned to receive KXHJ or a matching placebo; the treatment included a 10 g dose, administered twice daily for 4 weeks, in addition to conventional treatment. Participants were followed up for 12 weeks after the treatment.@*MAIN OUTCOME MEASURES@#The primary endpoints were treatment failure rate and all-cause mortality. Secondary endpoints included the length of hospitalization, overall survival, acute exacerbation rate, intubation rate, the modified British Medical Research Council (mMRC) score, and the St George's Respiratory Questionnaire for IPF (SGRQ-I) score.@*RESULTS@#The rate of treatment failure at 4 weeks was lower in the intervention group compared to the control group (risk ratio [RR]: 0.22; 95% confidence interval [CI]: 0.051 to 0.965, P = 0.023). There was no significant difference in all-cause mortality at 16 weeks (RR: 0.75; 95% CI: 0.179 to 3.138; P > 0.999) or in the acute exacerbation rate during the 12-week follow-up period (RR: 0.69; 95% CI: 0.334 to 1.434; P = 0.317). The intervention group had a shorter length of hospitalization than the control group (mean difference [MD]: -3.30 days; 95% CI, -6.300 to -0.300; P = 0.032). Significant differences in the mean change from baseline in the mMRC (between-group difference: -0.67; 95% CI: -0.89 to -0.44; P < 0.001) and SGRQ-I score (between-group difference: -10.36; 95% CI: -16.483 to -4.228; P = 0.001) were observed after 4 weeks, and also in the mMRC (between-group difference: -0.67; 95% CI: -0.91 to -0.43; P < 0.001) and SGRQ-I (between-group difference: -10.28; 95% CI, -15.838 to -4.718; P < 0.001) at 16 weeks. The difference in the adverse events was not significant.@*CONCLUSION@#KXHJ appears to be effective and safe for AE-IPF and can be considered a complementary treatment in patients with AE-IPF. As a preliminary exploratory study, our results provide a basis for further clinical research.@*TRIAL REGISTRATION@#Chinese Clinical Trial Registry (ChiCTR1900026289).

Résumé

Objective: To identify the risk factors in mortality of pediatric acute respiratory distress syndrome (PARDS) in pediatric intensive care unit (PICU). Methods: Second analysis of the data collected in the "efficacy of pulmonary surfactant (PS) in the treatment of children with moderate to severe PARDS" program. Retrospective case summary of the risk factors of mortality of children with moderate to severe PARDS who admitted in 14 participating tertiary PICU between December 2016 to December 2021. Differences in general condition, underlying diseases, oxygenation index, and mechanical ventilation were compared after the group was divided by survival at PICU discharge. When comparing between groups, the Mann-Whitney U test was used for measurement data, and the chi-square test was used for counting data. Receiver Operating Characteristic (ROC) curves were used to assess the accuracy of oxygen index (OI) in predicting mortality. Multivariate Logistic regression analysis was used to identify the risk factors for mortality. Results: Among 101 children with moderate to severe PARDS, 63 (62.4%) were males, 38 (37.6%) were females, aged (12±8) months. There were 23 cases in the non-survival group and 78 cases in the survival group. The combined rates of underlying diseases (52.2% (12/23) vs. 29.5% (23/78), χ2=4.04, P=0.045) and immune deficiency (30.4% (7/23) vs. 11.5% (9/78), χ2=4.76, P=0.029) in non-survival patients were significantly higher than those in survival patients, while the use of pulmonary surfactant (PS) was significantly lower (8.7% (2/23) vs. 41.0% (32/78), χ2=8.31, P=0.004). No significant differences existed in age, sex, pediatric critical illness score, etiology of PARDS, mechanical ventilation mode and fluid balance within 72 h (all P>0.05). OI on the first day (11.9(8.3, 17.1) vs.15.5(11.7, 23.0)), the second day (10.1(7.6, 16.6) vs.14.8(9.3, 26.2)) and the third day (9.2(6.6, 16.6) vs. 16.7(11.2, 31.4)) after PARDS identified were all higher in non-survival group compared to survival group (Z=-2.70, -2.52, -3.79 respectively, all P<0.05), and the improvement of OI in non-survival group was worse (0.03(-0.32, 0.31) vs. 0.32(-0.02, 0.56), Z=-2.49, P=0.013). ROC curve analysis showed that the OI on the thind day was more appropriate in predicting in-hospital mortality (area under the curve= 0.76, standard error 0.05,95%CI 0.65-0.87,P<0.001). When OI was set at 11.1, the sensitivity was 78.3% (95%CI 58.1%-90.3%), and the specificity was 60.3% (95%CI 49.2%-70.4%). Multivariate Logistic regression analysis showed that after adjusting for age, sex, pediatric critical illness score and fluid load within 72 h, no use of PS (OR=11.26, 95%CI 2.19-57.95, P=0.004), OI value on the third day (OR=7.93, 95%CI 1.51-41.69, P=0.014), and companied with immunodeficiency (OR=4.72, 95%CI 1.17-19.02, P=0.029) were independent risk factors for mortality in children with PARDS. Conclusions: The mortality of patients with moderate to severe PARDS is high, and immunodeficiency, no use of PS and OI on the third day after PARDS identified are the independent risk factors related to mortality. The OI on the third day after PARDS identified could be used to predict mortality.

Résumé

Objective: To examine the safety and efficacy of the uniportal video-assisted thoracoscopic decortication in treatment of drug-resistant tuberculosis empyema. Methods: From January 2018 to December 2020, 122 cases of tuberculous empyema treated by decortication in Department of Surgery, Wuhan Pulmonary Hospital were retrospectively analyzed, including 100 males and 22 females, aged(M(IQR)) 29.5(28.0) years (range: 13 to 70 years). According to the surgical approach and drug resistance, patients with drug-resistant tuberculosis who underwent uniportal video-assisted thoracoscopic decortication were included in group A (n=22), and those who underwent thoracotomy decortication were included in group B (n=28). Drug-sensitive patients who underwent uniportal video-assisted thoracoscopic decortication were included in group C (n=72). There was no statistical difference in the baseline data of the three groups (P>0.05). The operation, early postoperative recovery, and prognosis-related indicators were compared among three groups by Kruskal-Wallis test and χ2 test by Mann-Whitney U test and Bonferroni method between groups A and B, groups A and C. Results: The intraoperative blood loss of group A, group B, and group C was 200(475) ml, 300(200) ml, and 225(300) ml, respectively. There was no significant difference in intraoperative hemorrhage (H=2.74, P=0.254) and treatment outcome (χ2=4.76, P=0.575) among the three groups. Compared with group B, the operation time of group A (302.5(187.5) minutes vs. 200.0(60.0) minutes, U=171.0, P=0.007) and postoperative pulmonary reexpansion duration (4.5(3.0) months vs. 3.0 (2.2) months, U=146.5, P=0.032) were longer, and the postoperative drainage duration (9.5(7.8) days vs. 13.0(10.0) days, U=410.0, P=0.044), and the postoperative hospitalization time (12.0(7.8) days vs. 14.5(4.8) days, U=462.2, P=0.020) were shorter. There was no significant difference in complications between group A and group B (63.6%(14/22) vs. 71.4%(20/28), χ2=0.34, P=0.558). Compared with group C, the postoperative drainage duration of group A (9.5(7.8) days vs. 7.0(4.0) days, U=543.5, P=0.031), the postoperative hospitalization time (12.0(7.8) days vs. 9.0(4.0) days, U=533.0, P=0.031) and postoperative pulmonary reexpansion duration (4.5(3.0) months vs. 3.0(2.0) months, U=961.5, P=0.001) were longer. The operation time (302.5(187.5) minutes vs. 242.5(188.8) minutes, U=670.5, P=0.278), and complications (63.6%(14/22) vs. 40.3%(29/72), χ2=3.70, P=0.054) were not different between group A and group C. Conclusions: For drug-resistant tuberculous empyema, the uniportal video-assisted thoracoscopic decortication can achieve the same good therapeutic effect as drug-sensitive tuberculous empyema, and it is as safe as thoracotomy. At the same time, it has the advantage of minimally invasive and can accelerate the early postoperative recovery of patients.

Résumé

The present study explored the regularity of prescriptions for the treatment of intermediate and advanced lung cancer to provide references for clinical medication. CNKI, Wanfang, VIP, and CBM were searched for the research papers on the treatment of lung cancer by Chinese medicine published from database inception to May 31, 2021. The relevant information of qualified papers was extracted to establish a database. The Chinese medicines with frequency >3% underwent analysis of the latent structure and association rules by Lantern 5.0 and SPSS Molder 14.1, respectively, and the prescription regularity in the treatment of intermediate and advanced lung cancer was analyzed based on the frequency description. A total of 713 papers were included, involving 327 Chinese medicines with a cumulative frequency of 12 794 and 106 prescriptions with a cumulative frequency of 824. The commonly used Chinese medicines were dominated by deficiency-tonifying, heat-clearing, phlegm-resolving, and cough/dyspnea-relieving drugs, such as Astragali Radix, Atractylodis Macrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Ophiopogonis Radix, Poria, and Hedyotis Diffusa, which are cold, warm, and plain in nature and sweet, bitter, and pungent in flavor, and mainly act on lung, spleen, and stomach meridians. Commonly used prescriptions included Shashen Maidong Decoction, Liujunzi Decoction, and Baihe Gujin Decoction. The latent structure analysis revealed 32 latent variables and 65 hidden classes. Six comprehensive clustering models and 11 core prescriptions were obtained by professional knowledge inference. The common syndromes of intermediate and advanced lung cancer were inferred to be Qi and Yin deficiency in the lung, Qi deficiency in the lung and spleen, Yin deficiency in the liver and kidney, combined phlegm and stasis, phlegm-heat obstructing lung, and Qi stagnation and blood stasis. Forty-four strong associations were screened out by association rules analysis, including four pairwise strong associations(Polygonati Odorati Rhizoma→Ophiopogonis Radix, Polygonati Odorati Rhizoma→Glehniae Radix, Amomi Fructus→Atractylodis Macrocephalae Rhizoma, and Polygonati Rhizoma→Astragali Radix) and 40 triplet strong associations(such as Trichosanthis Radix+Glehniae Radix→Ophiopogonis Radix, Polygonati Odorati Rhizoma+Glehniae Radix→Ophiopogonis Radix, Trichosanthis Radix+Ophiopogonis Radix→Glehniae Radix, and Scutellariae Barbatae Herba+Codonopsis Radix→Hedyotis Diffusa). In the treatment of intermediate and advanced lung cancer, Qi-replenishing and Yin-nourishing drugs are mainly employed, assisted with cancer-resisting, toxin-removing, spleen-invigorating, phlegm/stasis-resolving, and blood-activating drugs based on syndrome differentiation. The roots were treated following the principles of tonifying lungs and replenishing the spleen, and symptoms following the principles of removing the toxin, dispelling stasis, and resolving phlegm.

Résumé

Objective: To investigate the prognostic factors of children with congenital heart disease (CHD) who had undergone cardiopulmonary resuscitation (CPR) in pediatric intensive care unit (PICU) in China. Methods: From November 2017 to October 2018, this retrospective multi-center study was conducted in 11 hospitals in China. It contained data from 281 cases who had undergone CPR and all of the subjects were divided into CHD group and non-CHD group. The general condition, duration of CPR, epinephrine doses during resuscitation, recovery of spontaneous circulation (ROSC), discharge survival rate and pediatric cerebral performance category in viable children at discharge were compared. According to whether malignant arrhythmia is the direct cause of cardiopulmonary arrest or not, children in CHD and non-CHD groups were divided into 2 subgroups: arrhythmia and non-arrhythmia, and the ROSC and survival rate to discharge were compared. Data in both groups were analyzed by t-test, chi-square analysis or ANOVA, and logistic regression were used to analyze the prognostic factors for ROSC and survival to discharge after cardiac arrest (CA). Results: The incidence of CA in PICU was 3.2% (372/11 588), and the implementation rate of CPR was 75.5% (281/372). There were 144 males and 137 females with median age of 32.8 (5.6, 42.7) months in all 281 CPA cases who received CPR. CHD group had 56 cases while non-CHD had 225 cases, with the percentage of 19.9% (56/281) and 80.1% (225/281) respectively. The proportion of female in CHD group was 60.7% (34/56) which was higher than that in non-CHD group (45.8%, 103/225) (χ2=4.00, P=0.045). There were no differences in ROSC and rate of survival to discharge between the two groups (P>0.05). The ROSC rate of children with arthythmid in CHD group was 70.0% (28/40), higher than 6/16 for non-arrhythmic children (χ2=5.06, P=0.024). At discharge, the pediatric cerebral performance category scores (1-3 scores) of CHD and non-CHD child were 50.9% (26/51) and 44.9% (92/205) respectively. Logistic regression analysis indicated that the independent prognostic factors of ROSC and survival to discharge in children with CHD were CPR duration (odds ratio (OR)=0.95, 0.97; 95%CI: 0.92~0.97, 0.95~0.99; both P<0.05) and epinephrine dosage (OR=0.87 and 0.79, 95%CI: 0.76-1.00 and 0.69-0.89, respectively; both P<0.05). Conclusions: There is no difference between CHD and non-CHD children in ROSC and survival rate of survival to discharge was low. The epinephrine dosage and the duration of CPR are related to the ROSC and survival to discharge of children with CHD.

Résumé

Objective:To explore the syndrome distribution of cough cases in ancient Chinese medical books. Method:A total of 9 323 cough cases in the database of lung diseases in ancient Chinese medical books were extracted. Lantern 5.0 was used to construct the latent structure model for the 100 manifest variables based on the first 50 symptoms and 50 Chinese herbal medicines, and different latent nodes were interpreted. The syndrome differentiation patterns of syndromes with symptoms and Chinese herbal medicine (formula) were quantitatively revealed by the comprehensive clustering weights of latent structure. The correlation of diseases with syndromes was fitted through the binary Logistic regression analysis. Result:There were 204 syndromes involved in 9 323 cough cases with 18 syndromes showing a frequency higher than 100. As demonstrated by the model established on the first 50 symptoms and 50 Chinese herbal medicines, 35 latent variables, 98 latent classes, and 10 comprehensive clustering models were obtained, where <italic>Z</italic>5<italic> </italic>was the highest in the threshold value (6.7), <italic>Z</italic>6 in the information coverage of productive cough (52%), and <italic>Z</italic>7 in the score (19). The binary Logistic regression model fitted the correlation between different disease types and five syndromes, where the dominance ratio of external wind to the syndrome of wind-heat invading lung reaching up to 88.919, those of syndrome of phlegm-heat accumulating in lung to diseased heat and sputum 51.594 and 15.861, and those of the syndrome of phlegm-dampness obstructing lung to dampness, phlegm, and fluid retention 31.415, 34.370, and 4.936, respectively. Conclusion:The newly discovered cough syndromes included lung heat and yin deficiency, external cold and internal fluid retention, weakness of spleen and stomach, and phlegm and blood stasis in lung. In most cases, multiple syndromes were observed clinically, such as syndrome of deficiency of both Qi and Yin in lung combined with yin deficiency in lung and kidney. Since differentiation of traditional Chinese medicine (TCM) syndrome is subjective, the weight can indicate the difference in the contributions of different symptoms to the syndrome, which is of guiding significance for syndrome inference. The latent structure model combined with Logistic regression analysis can solve the problem of quantification in TCM syndrome differentiation and can be used to explore the syndrome distribution of diseases.

Résumé

Objective:To determine the mortality and changing trend of primary liver cancer by using the death data of Chinese mainland from 2004 to 2018. Methods:The death certificate data was collected from China National Mortality Surveillance System from 2004 to 2018. The crude mortality rate(CMR)and age-standardized mortality rate(ASMR)of primary liver cancer in different ages, regions and living environments were calculated by Joinpoint regression model to analyze the basic situation and mortality trend. Results:From 2004 to 2018, there were 556 241 primary liver cancer deaths in China, with a CMR of 25.18/105 and an ASMR of 17.98/105. It suggested that the mortality of primary liver cancer was on a decreasing trend. During the 15 years, the ASMR of primary liver cancer was 15.56/105 in urban areas and 19.29/105 in rural areas. In urban areas, CMR was 32.89/105 in males and 12.14/105 in females, respectively; while in rural areas, CMR was 38.39/105 in males and 14.02/105 in females, respectively. The CMR in eastern, central and western urban regions was 22.25/105, 22.66/105 and 23.50/105, respectively. The CMR in the rural areas of these three regions was 27.82/105, 26.98/105 and 23.85/105, respectively. The patients were divided into four age groups: 0-19 years old, 20-39 years old, 40-59 years old, and more than 60 years old. The CMR of four groups in urban areas was 0.14/105, 2.59/105, 24.51/105 and 91.80/105. In rural areas, the CMR of four groups was 0.17/105, 4.05/105, 32.16/105 and 103.02/105. Conclusion:From 2004 to 2018, the mortality rate of liver cancer in China has a decreasing trend. However, the primary liver cancer death burden is still serious because of the large population base, severe aging population problem, and significant urban-rural and male-female disparities in China.

Résumé

ABSTRACT@#High viscous glass ionomer cement (HVGIC) was recently developed for atraumatic restorative treatment (ART). However, its moisture sensitivity remains a limitation thus protective coating application is recommended. This study investigated the effect of resin coating on the surface roughness and microhardness of two HVGICs (Riva Self Cure HVGIC [RV] and Equia® Forte Fil [EQ]) conditioned in food-simulating liquids (FSLs). Fifty standard disc-shaped samples were fabricated using customised stainless-steel mould (10 × 2 mm). Coating was applied on top surface of all samples and subsequently divided into five groups: air (control), distilled water, 0.02 N citric acid, heptane and 50% ethanol-water solution. The samples were conditioned in FSLs at 37°C for seven days. Subsequently, the surface roughness and microhardness of samples were measured using optical profilometry and microhardness tester, respectively. SEM analysis was done for qualitative observation of surface morphological changes. Data were analysed using one-way ANOVA, two-way ANOVA and posthoc Tukey’s test (α = 0.05). Interestingly, the results revealed that surface roughness was significantly influenced by FSLs immersion, presence of coating and the materials itself (p < 0.001). The lowest surface roughness was found on control coated samples: RV (50.98±4.25) nm and EQ (62.77±3.92) nm, while the highest values seen on uncoated surfaces in citric acid: RV (505.26±31.10) nm and EQ (350.33±15.36) nm. RV samples had the lowest microhardness of 54.97±2.48 Vickers hardness number (VHN) post-immersion in citric acid. In conclusion, with the exception of RV conditioned in heptane and ethanol, the uncoated HVGICs generally had higher surface roughness than the coated HVGICs. HVGICs conditioned in citric acid showed the most significant increase in surface roughness and reduction in microhardness.

Résumé

OBJECTIVE@#Critical effective constituents were identified from Bufei Yishen formula (BYF), a traditional herbal compound and combined as effective-constituent compatibility (ECC) of BYF I, which may have potential bioactive equivalence to BYF.@*METHODS@#The active constituents of BYF were identified using four cellular models and categorised into Groups 1 (Bufeiqi), 2 (Bushen), 3 (Huatan) and 4 (Huoxue) according to Chinese medicinal theory. An orthogonal design and a combination method were used to determine the optimal ratios of effective constituents in each group and the ratios of "Groups 1 to 4" according to their pharmacological activity. We also comprehensively assessed bioactive equivalence between the BYF and the ECC of BYF I in a rat model of chronic obstructive pulmonary disease (COPD).@*RESULTS@#We identified 12 active constituents in BYF. The numbers of constituents in Groups 1 to 4 were 3, 2, 5 and 2, respectively. We identified the optimal ratios of effective constituents within each group. In Group 1, total ginsenosides:Astragalus polysaccharide:astragaloside IV ratio was 9:5:2. In Group 2, icariin:schisandrin B ratio was 100:12.5. In Group 3, nobiletin:hesperidin:peimine:peiminine:kaempferol ratio was 4:30:6.25:0:0. In Group 4, paeoniflorin:paeonol ratio was 4:1. An orthogonal design was then used to establish the optimal ratios of Group 1, Group 2, Group 3 and Group 4 in ECC of BYF I. The ratio for total ginsenosides:Astragalus polysaccharide:astragaloside IV:icariin:schisandrin B:nobiletin:hesperidin:peimine:paeoniflorin:paeonol was determined to be 22.5:12.5:5:100:12.5:4:30:6.25:25:6.25. A comprehensive evaluation confirmed that ECC of BYF I presented with bioactive equivalence to the original BYF.@*CONCLUSION@#Based on the ECC of traditional Chinese medicine formula method, the effective constituents of BYF were identified and combined in a fixed ratio as ECC of BYF I that was as effective as BYF itself in treating rats with COPD.

Résumé

Objective:To explore cough cases recorded in ancient traditional Chinese medicine (TCM) books based on the Rules of Latent Structure Differentiation. Method:The 9 323 cough cases in the database of ancient TCM books and pulmonary diseases were extracted. At first, Lantern 5.0 software was used to construct the top 120 TCM hidden structure model with the frequency>100. Then, the obtained hidden variables were comprehensively clustered and interpreted. Result:The 46 hidden variables and 114 hidden classes were obtained through the modeling of 120 traditional Chinese medicines. According to the bayesian information measure (BIC) score, the model score was -161 242.92. The model diagram was formed with Y0, Y5, Y7, Y13, Y35 and Y38 as the cores, and Y36, Y38, Y24, Y19 and Y17 involved 4 hidden classes. Ten comprehensive clustering models were summarized according to the hidden structure flow chart, among which the highest score of Z5 external cold and internal decoction syndrome was 8.4, indicating that the result of syndrome differentiation rules of Z5 had a high degree of support, and the highest mutual information degree and information coverage of Pinellia sinensis were 0.31 and 63%. Z2 had a low score for the syndrome of deficiency of lung qi and Yin, which was -2, and Schisandra had the lowest score of -15, indicating that the syndrome differentiation rules of Z2 was less supportive. Forsythia and Notopterygium both had the highest score of Z6 wind-heat attack lung syndrome and Z10 phlegm and blood-stasis pulmonary syndrome, which was 19.1, indicating that these two TCMs had a great contribution to it. According to the test, the common syndromes of cough were cold and dryness attacking the lung, kidney-Yin deficiency, kidney-Yin deficiency of the lung, cold and internal decoction, wind heat invading the lung, liver fire invading the lung, lung heat burning, phlegm-dampness blocking the lung, phlegm-stasis blocking the lung. The newly discovered cough syndromes were external cold and internal rheum syndrome and phlegm-stasis blocking the lung syndrome. Conclusion:Based on the syndrome differentiation rules of hidden structure, the improved classification of cough syndromes provides ideas for the demonstration of tacit knowledge of TCM and methodological reference for the improvement of syndromes of other diseases, and is conducive to the development of valuable new prescriptions.
