ABSTRACT

From January 1, 2004 to July 21, 2016 a total of 2 796 cases of adverse drug reaction/adverse event(ADR/AE) after the use of Xianling Gubao Capsules/Tablets were reported by National Adverse Drug Reaction Monitoring Center. The following results were obtained by analyzing the reports of 2 796 cases of adverse drug reactions/adverse drug events after the use of Xianling Gubao Capsules/Tablets. A total of 75 patients, accounting for 2.68% of the total ADR/AE time, had severe ADR/AE events. Among them, 30 patients were aged 65 and above, accounting for 40.00% of the total number of severe ADR/AE patients. All the patients with ADR/AE were aged 45-64 years, which totaled 1 346 cases and took up 48.14% of the total patients with ADR/AE. All of ADR/AE cases and severe ADR/AE cases were orally given Xianling Gubao Capsules/Tablets. Females accounted for 52.50% and 76.00%, respectively, and the proportion of females was significantly higher than that of males. Among patients with a medical history of ADR/AE, severe ADR/AE was higher than the average, accounting for about 1.33%. The proportion of cases orally given 1-3 tablets of Xianling Gubao Capsules/Tablets in all ADR/AE cases and severe ADR/AE cases was 95.32% and 96.00%, which conformed to the usage in the package insert. All ADR/AE cases and severe ADR/AE cases orally given Xianling Gubao Capsules/Tablets twice daily occupied the highest proportions, or 77.00% and 61.00%, respectively. The proportion of severe ADR/AE cases orally given Xianling Gubao Capsules/Tablets was slightly higher than that of all ADR/AE cases in the medication frequency, which didn't conform to the usage in the package insert. All the symptoms of ADR/AE orally given Xianling Gubao Capsules showed many manifestations, and the top 10 symptoms were nausea, rash, itching, stomach dysfunction, vomiting, abdominal pain, dizziness, diarrhea, anaphylaxis, and reflux heartburn. The symptoms of severe ADR/AE after oral administration of Xianling Gubao Capsules were varied, and the top 10 symptoms were abnormal liver function, rash, suffocation, itching, dizziness, vomiting, anaphylaxis, abdominal pain, weakness, and convulsions. Abnormal liver function accounted for 44.12%. All of ADR/AE cases occurred within 2 days after oral administration of Xianling Gubao Capsules/Tablets, accounting for 54.26%. Severe ADR/AE occurred within 2 days after the use of Xianling Gubao Capsules/Tablets, accounting for 25.34%. The proportion of ADR/AE cases occurring within 15 days after oral administration of Xianling Gubao Capsules/Tablets increased again(57.33%). The overall trend contained two peaks.

ABSTRACT

<p><b>OBJECTIVE</b>To verify the efficacy and safety of Quxie Capsule () in patients with metastatic colorectal cancer (mCRC).</p><p><b>METHODS</b>The present study was a randomized, double-blind, placebo-controlled trial. Sixty patients with mCRC were randomized into two groups at a 1:1 ratio by sealed envelope. The treatment group received conventional therapy combined with Quxie Capsule for 3 months. The control group was treated with conventional therapy combined with placebo for 3 months. Main outcome measures were overall survival (OS) and progression-free survival (PFS). Subgroup analysis was performed according to age, right or left-sided disease, and second-line therapy to determine the differences in PFS and OS between the two groups. Patients were followed up every 3 months until Dec 31st 2016.</p><p><b>RESULTS</b>The median OS was 23 months in the treatment group [95% confidence interval (CI): 15-not calculated] vs. 14 months in the control group (95% CI: 11-22, P=0.060). The OS of the treatment group tended to be longer than that of the control group (P>0.05). In the subgroups of patients <65 years old, left-sided colon, and 2nd-line therapy, the treatment group showed a significant survival benefit compared with the control group (P=0.006, 0.038, 0.013, respectively). There were no significant differences between the two groups in PFS (P>0.05). Safety analysis showed no severe hematological toxicity or liver and renal function injury in the treatment group.</p><p><b>CONCLUSIONS</b>Quxie Capsule showed good safety and efficacy, and could prolong the OS of patients with mCRC.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the efficacy of integrated Chinese and Western medicine (IM) in the treatment of metastatic colorectal cancer (mCRC) in a cohort study.</p><p><b>METHODS</b>The survival outcome of patients receiving IM was compared with that of patients receiving Western medicine alone. The study design was adopted with "continuous administration of Chinese medicine for ⩾ 3 months" as the exposure factor. Patients who met this exposure factor were assigned to the IM cohort (Group A, 110 patients). Patients who did not meet this exposure factor were assigned to the Western medicine cohort (Group B, 225 patients). The overall survival (OS), progression-free survival (PFS), and 1st year, 2nd year, and 3rd year survival in the two cohorts were compared.</p><p><b>RESULTS</b>The median OS in Group A and B were 18 months [95% confidence interval (CI) 15-21] and 16 months (95% CI 14-18), respectively, and the median PFS in Group A and B were 6 months (95% CI 4-7) and 5 months (95% CI 4-6), respectively. No statistically significant differences were observed between the groups (P=0.186, P=0.223). Group A demonstrated significantly longer OS and PFS than Group B in the following subgroups: female patients, patients with lesions in the right half of the colon, and those who received first-line treatment (P<0.05). In the subgroup of elderly patients (age>65 years), the OS in Group A was longer than that in Group B (P<0.05).</p><p><b>CONCLUSION</b>IM could prolong the survival of patients with mCRC.

ABSTRACT

This study was aimed to obtain the incidence of adverse drug reaction (ADR) of Diemailing Kudiezi injection, explore its characteristics, related risk factors and application in real world. A prospective single cohort study was conducted from 25 hospitals (including Chinese medicine hospitals and Western medicine hospitals) for 4 years. 30 233 consecutive inpatients using Diemailing Kudiezi injection were observed. Their general information was analyzed by using statistic frequency description. Association rules were used to analyze the correlation between comorbidities or drug combinations; the influential factors for ADRs were initially screened by using cross contingency method and Chi-square test, and then Group LASSAO method was used for further analysis. 54 patients with adverse drug events and 30 patients with ADRs were reported among 30 233 patients, with a total ADR incidence of 0.099%[95%CI (0.06%, 0.13%)]. There were 27 patients identified as the "general" ADR, one patients with "severe" ADR (anaphylactic shock) and two patients with new ADRs. ADR occurred most in 30 min after using Diemailing Kudiezi injection, in a total of 16 patients. The most ADRs were palpitation, vomiting, chills, pruritus and rash, 6 times for each symptom. Diemailing Kudiezi injection was well tolerated in the general population. The overall incidence of adverse reactions was rare, with high safety. However, the real incidence of ADRs may be underestimated in this study, and the blood samples were not obtained for the patients, so further mechanism studies shall be conducted.

ABSTRACT

This is a study based on hospital intensive monitoring to explore medication use of Diemailing Kudiezi injection(one Chinese herbal medicine injection) in real word in the patients with cerebral infarction. The active monitoring model was adopted and hospital intensive monitoring on safety of 7 189 cases of patients with cerebral infarction was conducted to obtain the drug use information of Diemailing injection. The results were analyzed by using statistical description and association rule method. The statistical description and association rule analysis were conducted based on patients' basic demographic characteristics, use of Diemailing injection and combined use of drugs. Sixty-two percent(4 437/7 189) of the patients were from traditional Chinese medicine hospitals as compared with 39%(2 752/7 189) from western medicine hospitals; 84%(6 003/7 189) of the patients were from tertiary hospitals as compared with 16%(1 186/7 189) from second-class hospitals. The hospitals were mostly located in north China. Drug related indicators such as a single dripping speed, stash time after allocating transfusion, duration of injection, and injecting room temperature were not noted in instruction manual. It was also found that there were off label use in the practice, for instance, non-intravenous infusion, >14 d treatment course, use of non-designated solvent, and a single dose>40 mL or<10 mL. Analysis of association rules showed that only Edaravone among the most frequent combined drugs was listed in the current guideline in China, and the other three most frequent combined drugs deproteinized calf blood extractive injection, Cinepazide Maleate injection and Alprostadil injection were used with little evidence. Diemailing+Aspirin+Alprostadil was the most common combined use in our study, but the recommended clopidogrel+Aspirin was not found in this study. The drug use situation of Diemailing injection in the real world was obtained by data analysis on large size samples, providing basic reference information for clinicians and researchers. However, efficacy was not concerned in this study, so efficacy-related information could not be explained.

The results would provide reference for the secondary prevention on the recovery stage of ischemic stroke. 696 patients from 12 Class III Grade I hospitals nationwide were divided into 2 groups by central randomization system. The study group, 344 cases, were treated with Naoshuantong capsule plus Aspirin, and the control group, 352 cases, were treated with Aspirin. The patients were treated for 6 months. At the end of treatment, SS-QOL used for evaluating the quality of life was observed. The safety index was defined by adverse observation event. The incidence of adverse events and laboratory tests results were observed before and after treatment at the same time. The results indicated that compared to the control group, the treatment group had significant statistical difference in the impact of effort, self-care ability and the the work or labor ability of patients (P < 0.05). No serious adverse events were observed. Naoshuantong capsule showed some superiority to Asprin on improving the quality of life on patients with ischemic stroke, and it could be used in secondary prevention on the recovery stage of ischemic stroke. Naoshuantong capsule is safe and effective in the treatment of convalescence ischemic stroke.

ABSTRACT

<p><b>OBJECTIVE</b>To introduce practical diagnostic criterion of blood stasis syndrome (BSS), and to evaluate its reliability and validity.</p><p><b>METHODS</b>By referring to three diagnostic criteria of BSS [practical diagnostic criterion of BSS (criterion A), diagnostic criterion of BSS in 1986 (criterion B), Consensus of Integrative Medicine on BSS Diagnosis in 2011 (criterion C)], 712 patients from different departments of Xiyuan Hospital were recruited. The reliability of criterion A and its consistency with the other two criteria were assessed using Kappa coefficient. A Bayesian approach was also employed to assess the sensitivity and specificity of criterion A.</p><p><b>RESULTS</b>According to the consistency check, criterion A presented good consistency when used by different researchers (the diagnostic accordance rate was 91. 96%, Kappa =0. 82, P <0.001). Meanwhile, there was an acceptable diagnostic consistency among the three diagnostic criteria. Bayesian estimation suggested that criterion A had higher sensitivity but similar specificity, as compared with criterion B or criterion C. Compared with criterion B [the median of sensitivity and specificity were 0. 762 (95% Cl: 0. 731 -0. 790) and 0. 902 (95% Cl: 0. 858 -0. 936) respectively, the median of sensitivity and specificity of criterion A were 0. 911 (95% CI: 0. 888 - 0. 930) and 0. 875 (95% CI: 0. 826 - 0. 915) respectively. Estimating the difference between criterion A and B, the median of sensitivity and specificity were 0. 149 (95% CI: 0. 112 -0.184) and -0. 026 (95% CI:-0. 085 -0. 033) respectively. Compared with criterion C [the median of sensitivity and specificity were 0. 831 (95% Cl: 0. 804 -0. 857) and 0. 892 (95% CI: 0. 848 - 0. 926) respectively], the median of sensitivity and specificity of criterion A were 0. 912 (95% CI: 0. 889 -0. 932) and 0. 880 (95%CI: 0. 833 - 0.919) respectively. Estimating the difference between criterion A and C, the median of sensitivity and specificity were 0. 081 (95% CI: 0.047 - 0.114) and -0.011 (95%CI: -0.070 -0.046) respectively.</p><p><b>CONCLUSION</b>Compared with criterion B and C, criterion A not only had better reliability, but also could significantly improve the sensitivity without obviously lowering the specificity.</p>

ABSTRACT

Viral hepatitis was the most common infectious disease in china. But the diagnosis and treatment were varied because the viral hepatitis patients were hospitalized in different kinds of hospital such as infectious disease hospital, general hospital and Chinese medical hospital. It was necessary to know clinical characters and information of viral hepatitis patients in different hospitals. The general information, subtype distribution, prognosis, complication, medication and relations of onset with solar term from 41 180 viral hepatitis patients based on HIS data were analyzed. It was found that the age of patients between 18 to 59 years old was most; most patients were males. The national basic medical insurance was the most type of payment. The outcome of viral hepatitis in the youth and female were better than that in the old and male. Acute hepatitis was easer to restore than chronic hepatitis. Liver cirrhosis and hepatocellular carcinoma were the two most complications. The peak of onset was during summer solstice, slight heat and great heat. The most common Chinese medicine was Diammonium glycyrrhizinate and the most common western medicine was reduced glutathione. The combination of D. glycyrrhizinate with reduced glutathione, polyene phosphatidylcholine and thymosin was the main pattern. But It was not knew if the combination of western and Chinese medicine was the most effective therapy to protect liver function. It was necessary to take deeply research of the relationship between the combination therapy and their effectiveness.

ABSTRACT

This study analyze the characteristics and clinical medicine in 17 hospitals all over China, based on hospital information system diagnostic information database, including 4 497 cases of hospitalized patients with Parkinson's syndrome. Results indicate, the most common comorbidities are infarction, hypertension, coronary heart disease, diabetes and lung infections, including cerebral infarction, the combined incidence of hypertension in men reached 33.46% and 30.05%, respectively, it is slightly lower in the females. Men with coronary heart disease are more than women, women with diabetes and bone disease are more than men. Combined incidence of the disease increases with age, vascular factors occupy an important position. The most common combined diseases in patients with 90 years of age or older are coronary heart disease, lung infection, and often accompanied by metabolic disorders and nutritional emergency, critical care. Constipation, depression, anxiety, sleep disorders, cognitive impairment are common non-motor symptoms. The drug categories associated with Parkinson's core symptoms treatment are about 20% to 30% of clinical medicine, the others are associated with the treatment of combined disease, clinical medicine and disease spectrum consistent. Blood circulation topped Chinese agents applied frequency, reaching 44.52%; laxative drugs accounted for 11.66%; detoxification agent representing 9.46%. The first twenty Chinese medicine of the applying frequency reached 56.07% of the total utilization, including 12 kinds of traditional Chinese medicine injections, accounting for 60%. Therefore, in the diagnosis and treatment of Parkinsons syndrome, the treatment of comorbidities is very important, more attentions should be paid to vascular factors of the disease, Chinese medicine should be more concerned to improve the non-motor symptoms, give full play to the pharmaceutical multi-target, the overall regulation of advantages, integrative medicine, and improve the quality of life of patients.

ABSTRACT

Chinese medicine (CM) clinical efficacy evaluation research involves the longitudinal multivariate measurement which means that patients are measured repeatedly and each patient is measured by several indicators on each fixed cross-section. Although each indicator can be evaluated separately with a longitudinal linear mixed model, it is important to consider all the endpoints together especially when researchers pay special attention to the change of the conjoint efficacy for several indicators in one patient. In this article, we introduce a latent variable linear mixed model to the CM conjoint efficacy evaluation and discuss why and how to analyze the longitudinal multivariate endpoint data in the clinical CM efficacy evaluation research. It may lead to the new insight of using such methodology in the field of conjoint efficacy evaluating of CM study. And with the definition of syndrome and symptom in the CM theory, the applied discussion brings the insight of CM syndrome evaluating in future. We illustrate this methodology using an example of CM efficacy evaluation from an ischemic stroke research.

ABSTRACT

Syndrome differentiation is the character of Chinese medicine (CM). Disease differentiation is the principle of Western medicine (WM). Identifying basic syndromes feature and structure of disease of WM is an important avenue for prevention and treatment of integrated Chinese and Western medicine. The idea here is first to divide all patients suffering from a disease of WM into several groups in the light of the stage of the disease, and secondly to identify basic syndromes feature in a distinct stage, and finally to achieve the purpose of syndrome differentiation. Syndrome differentiation is simply taken as a classifier that classifies patients into distinct classes primarily based on overall observation of their symptoms. Previous clustering methods are unable to cope with the complexity of CM. We therefore show a new multi-dimensional clustering method in the form of general latent structure (GLS) model, which is a suitable statistical learning technique of latent class analysis. In this paper, we learn an optimal GLS model which reflects much better model quality compared with other latent class models from the osteoporosis patient of community women (OPCW) real data including 40-65 year-old women whose bone mineral density (BMD) is less than mean-2.0 standard deviation (M-2.0SD). Further, we illustrate a case analysis of statistical identification of CM syndromes feature and structure of OPCW from qualitative and quantitative contents through the GLS model. Our analysis has discovered natural clusters and structures that correspond well to CM basic syndrome and factors of osteoporosis patients (OP). The GLS model suggests the possibility of establishing objective and quantitative diagnosis standards for syndrome differentiation on OPCW. Hence, for the future it can provide a reference for the similar study from the perspective of a combination of disease differentiation and syndrome differentiation.
