This study was aimed to observe influence of disease/syndrome on the toxicity and effect of aconite roots, in order to reveal relationship among disease/syndrome, toxicity and effect. The mice model of cold syn-drome was establish by wind-cold stimulation. The pain model was established by intraperitioneal injection of glacial acetic acid. Then, LD50 and ED50 of analgesic effect were compared, as well as the therapeutic index (TI) of crude aconite roots. The rat model of cold syndrome was also established by wind-cold stimulation. And the rheumatoid arthritis (RA) model was established by intracutaneous injection of CII and CFA. TD50 of cardiac toxic-ity and arthroncus degree of prepared aconite roots were compared among the normal rats, RA rats, RA with wind-cold stimulation rats according to the recording of lead II ECG. The results showed that after wind-cold stimulation, mice and rats appeared with symptoms which were similar to Chinese medicine cold syndrome. Com-pared with normal mice, LD50 and TI increased, but ED50 decreased in the group of wind-cold stimulation after using powders of crude aconite roots. Compared with normal rats, TD50 of cardiac toxicity and arthroncus degree in-creased in groups of RA and RA with wind-cold stimulation after using prepared aconite roots. It was concluded that in the case of disease/syndrome state, the toxicity of aconite roots decreased, but its effect increased. It sug-gested that there is a significant correlation among disease/syndrome, toxicity and effect.

Objective To investigate the curative effect of bronchoalveolar lavage with fiberoptic bronchoscopy combined with vibration sputum drainage in the treatment of severe pneumonia patients undergoing mechanical ventilation (MV).Methods A prospective randomized controlled trial was conducted. 286 severe pneumonia patients undergoing MV admitted to intensive care unit (ICU) of Hunan People's Hospital from January 2014 to July 2016 were enrolled, and they were divided into control group and observation group according to random number table, with 143 patients in each group. Patients in both groups received sensitive antibiotics for anti-infection, etiological treatment, and calefacient and humidifying treatment. The patients in the control group received bronchoalveolar lavage with fiberoptic bronchoscopy, and those in the observation group received bronchoalveolar lavage combined with vibration sputum drainage. The parameters of respiratory function and inflammation before and after treatment, curative effect, and prognosis were compared between the two groups.Results ① There were no significant differences in respiratory function parameters between the two groups before treatment, 2 hours after treatment, the parameters were improved in both groups. Moreover, oxygenation index (PaO2/FiO2) in observation group was significantly higher than that of control group [mmHg (1 mmHg = 0.133 kPa): 379.1±20.2 vs. 351.8±24.7], and arterial partial pressure of carbon dioxide (PaCO2) and airway resistance (Raw) were significantly lower than those of the control group[PaCO2 (mmHg): 36.5±5.8 vs. 45.3±6.9, Raw (cmH2O, 1 cmH2O = 0.098 kPa): 12.9±0.6 vs. 13.1±0.8, allP < 0.01]. ② There were no significant differences in inflammation parameters between the two groups before treatment, 24 hours after intervention, which were significantly decreased in both groups. Moreover, white blood cell count (WBC), procalcitonin (PCT) and C-reactive protein (CRP) in the observation group were significantly lower than those of the control group [WBC (×109/L): 8.2±1.7 vs. 12.8±3.7, PCT (μg/L): 15.4±2.4 vs. 21.8±3.1, CRP (mg/L): 37.1±6.1 vs. 67.2±7.2, allP < 0.01]. ③ Compared with the control group, the treatment efficiency of observation group was improved [95.1% (136/143) vs. 87.4% (125/143)], the quantity of sputum excretion was increased (mL: 49.2±12.5 vs. 36.9±11.0), duration of MV and length of ICU stay were significantly shortened (days: 6.4±3.6 vs. 9.4±2.1, 8.6±5.7 vs. 12.4±4.6, bothP < 0.01), however, there was no significantly statistical difference in 28-day mortality between control group and observation group [2.8% (4/143) vs. 2.1% (3/143),P > 0.05].Conclusion Compared with bronchoalveolar lavage with fiberoptic bronchoscopy alone, the treatment of bronchoalveolar lavage combined with vibration sputum drainage is more effective in sputum excretion for severe pneumonia patients undergoing MV, which could improve the respiratory function, reduce infection, shorten the duration of MV and the length of ICU stay, and improve the recovery.

Toxicity of Chinese materia medica (CMM) is an important part of Chinese herbal nature theory. In clinical application, the dosage, time limitation and compatibility of CMM is mainly determined by toxicity. At present, there is no uniform toxicity classification standard for the evaluation of Chinese herbal toxicity. Therefore, it is significant to research toxicity classification of CMM. The current situation of toxicity classification of CMM is reviewed in this paper, and proposed research thoughts are as follows: the measurement of toxicity parameters, the confirmation of poisoning target organs, the investigation on toxic mechanism by serum pharmacology and toxicokinetics, the comprehensive evaluation on toxicity based on quantitative theory.

Objective:To explore the therapeutic characteristics of population with gout achieving treat-to-target (T2T) indicators through real-world research and evaluate their safety.Methods:A total of 3 287 patients diagnosed with gout by rheumatologists in 21 first-class tertiary hospitals in 10 provinces, municipalities, and autonomous regions in China from January 2015 to December 2021 were included in this polycentric cross-sectional study. The database included patients′ general information, disease characteristics, and clinical application of traditional Chinese and Western medicine treatment measures. SPSS and Excel software were used for data analysis. Frequency analysis, cluster analysis, and factor analysis were used to summarize the characteristics and rules of treatment measures for patients with gout who achieved the target after treatment. The occurrence of adverse events (AE) was recorded during treatment.Results:After treatment, 691 visits (7%) achieved the serum urate (SUA) target, and the most frequent use of urate-lowering therapy (ULT) was febuxostat, followed by benzbromarone. The most common treatment options were following: GroupⅠ: traditional Chinese medicine (TCM) decoction-TCM external treatment-physical exercise-proprietary Chinese medicine; GroupⅡ: ferulic acid-nonsteroidal anti-inflammatory drugs (NSAIDs); Group Ⅲ: allopurinol-sodium bicarbonate-benzbromarone; Group Ⅳ: glucocorticoid-colchicine; Group Ⅴ: febuxostat. A total of 5 898 visits (60%) chieved manifestations of joint pain VAS scores target, and the most frequently used drug to control joint symptoms was NSAIDs. The frequency of use of drugs to control joint symptoms were 2 118 times (usage rate reached 35.9%), while the frequency of ULT were 2 504 times (usage rate reached 42.5%), which was higher than the joint symptom control drug. The most common treatment options were following: Group Ⅰ: proprietary Chinese medicine-TCM decoction-TCM external treatment-physical exercise; Group Ⅱ: NSAIDs-colchicine hormones; Group Ⅲ: allopurinol, Group Ⅳ: benzbromarone; Group Ⅴ: febuxostat. A total of 59 adverse events occurred during treatment.Conclusion:The proportions of gout patients who reach target serum urate level & good control of joint symptoms are both very low, and ULT and anti-inflammatory prescription patterns are very different from international guidelines, so it is necessary to strengthen the standardized management of gout patients. At the same time, life intervention measures account for a certain proportion of the treatment plans for the T2T population, and further exploration is needed.

OBJECTIVE:
To identify the screening time and prepare a screening schedule for outpatients with acute fatty liver of pregnancy (AFLP).
METHODS:
AFLP patients who admitted to Xiangya Hospital and the Second Xiangya Hospital, Central South University, Hunan, China between November, 2006 and December, 2013, were retrospectively studied. The diagnosis of 78 AFLP patients met the domestic clinical and laboratory criteria and the Swansea criteria. Clinical and laboratory data obtained on admission were used for analysis. Contrastive analysis was conducted within our data and other large medical centers or general hospitals.
RESULTS:
The difference between domestic clinical and laboratory criteria and Swansea criteria in diagnosing AFLP patients in the 2 hospitals mentioned above was significant (P<0.05). The maternal mortality was 14.10% (11/78) and perinatal mortality was 17.95 % (14/78). The mean gestational age at delivery was 35.6 weeks. Based on the clinical and laboratory data, more than 85% of AFLP patients showed abnormal levels of transaminase, bilirubin, and white blood cells, as well as coagulation dysfunction. Gastrointestinal symptoms, such as abdominal pain and vomiting, jaundice, renal impairment and ascites or bright liver on ultrasound scan, were showed in 50%-85% of AFLP patients. Less than 50% of patients suffered from low blood sugar, high blood ammonia or hepatic encephalopathy.
CONCLUSION
The 34th gestation week might be important time for screening AFLP outpatients. Gastrointestinal symptoms, blood routine, liver function, and coagulant function tests are recommended as the first grade screening indicators. Renal function, blood sugar test, and abdominal ultrasound could be the second grade screening indicators for AFLP outpatients.

Listeria monocytogenes (Lm) is zoonotic pathogen that can cause listeriosis, and vaccine is one of the effective methods to prevent this pathogen infection. In this study, we developed a novel vaccine that is a mixture of inactivated bacteria and Montanide™ ISA 61 VG, a mineral oil adjuvant, and evaluated the safety and immune response characteristics of this vaccine. The mice immunized with the ISA 61 VG adjuvant had high safety, and it could induce significantly higher titer of anti-listeriolysin O (LLO) antibody and higher value of IgG2a/IgG1 ratio compared with the group without the adjuvant. In particular, it could provide 100% immune protection against lethal doses of Lm challenge in mice. In summary, ISA 61VG adjuvant significantly enhanced the ability of inactivated listeria vaccine to induce humoral and cellular immune responses, thereby enhanced the protective immune response in the host, and it is a potential vaccine candidate for the prevention of Lm infection in humans and animals.
