Compound 1 is a new indole alkaloid. Compounds 6 and 7 were isolated from this plant for the first time.

Objective To explore a more effective way to enhance the clinical efficacy of cluster immunotherapy for perennial allergic rhinitis. Methods A total of 60 perennial allergic rhinitis patients were evenly randomized into treatment goup and control group. The two groups were given cluster immunotherapy, and the treatment group was given daily vesiculating moxibustion additionally . Before and after treatment, the scores of traditional Chinese medical constitution and the rhinitis quality of life ( QOL) were observed, and one year after treatment, the therapeutic effect and safety were evaluated. Results ( 1) One year after treatment, the treatment group showed better total clinical efficiency than the control group ( 96.67% vs 80.00%, P<0.05). ( 2) After treatment, the average scores of Qi deficiency constitution, yang deficiency constitution and special constitution were significantly lower than those before treatment in the treatment group ( P<0.01). The improvement of Qi deficiency constitution and yang deficiency constitution in the treatment group was superior to that in the control group ( P<0.05). ( 3) The total QOL scores and the scores of each dimension of QOL scale were improved in both groups, and the differences were significant except for the emotion dimension ( P<0.01). Insignificant differences were shown between the two groups after treatment ( P>0.05). ( 4) Two cases had grade 1 general adverse reaction and 5 cases had local adverse reaction during cluster immunotherapy. During vesiculating moxibustion, 3 cases had blistering and the blistering disappeared after symptomatic treatment. Conclusion Daily vesiculating moxibustion combined with cluster immunity therapy is effective for the treatment of allergic rhinitis, showing good effect on improving Qi deficiency constitution, yang deficiency constitution and special constitution as well as the quality of life of the patients.

OBJECTIVE: To investigate the relationship between the prevalent species and the seasonal drift law of airborne fungi and respiratory allergic disease in the city of Wuhan. METHOD: Airborne fungi was investigated by exposed sides from 2007 to 2008, and 1674 patients with respiratory allergic disease that were used to do allergens skin test simultaneously, in order to analyze the simultaneous. RESULT: Airborne fungi could be detected in air all over the year. In 2007, the exposed films collected 26 734 fungi spores, and 686 other fungi (hypha and not well known fungi), to the sum of 27420. Otherwise, in 2008, the exposed films collected 26 531 fungi spores, and 730 other fungi, to the sum of 27 261. In the survey, 17 types of species of the collected fungi spores were identified, and the predominant species were alternaria sp, ustilaginales, deightoniella sp, uredinales, and the quantity of Fungi alternaria was most of all . And the peak period mainly concentrated from April to June, and from September to October. Otherwise, the positive rate of fungi skin test in patients with respiratory allergic disease was 10.48% in 2007, but 10.07% in 2008. The main period of onset of respiratory allergic disease was from April to June, and from September to October, similar as the seasonal drift law of airborne fungi. CONCLUSION The period of onset of respiratory allergic disease was consistent with the seasonal drift law of airborne fungi.

BACKGROUND:Mechanical stress plays an important role in the progressive collapse in osteonecrosis of the femoral head.Therefore,the bone structure of weight-bearing area may be the risk factor for collapse.OBJECTIVE:To investigate the relationship between the bone preservation of weight-bearing area and collapse progression in necrotic femoral head.METHODS:Eighty-seven patients (102 hips) with ARCO stage Ⅱ osteonecrosis of the femoral head,diagnosed by MRI,were enrolled.All patients underwent a natural progression.Collapse and bone involvement of the weight-bearing area were viewed by anteroposterior and frog-leg lateral radiographs.According to the location of the necrotic lesion on the anterolateral portion of the femoral head,the necrosis was divided into three types:type 1,the posteromedial and central portions;type 2,part of the anterolateral portion;type 3,the entire anterolateral portion.The collapse rate and the time to collapse in different types were assessed.RESULTS AND CONCLUSION:(1) All patients were followed up for 3-58 months.(2) Of the 60 hips with collapse,46 (76.7％) hip collapse was identified on anteroposterior radiograph.On frog-leg lateral radiograph showing collapsed femoral head could be identified in 57 (95.0％) hips,which was significantly different (P ＜ 0.01).(3) In all 102 hips,the collapse rate in type 3 osteonecrosis of the femoral head was significantly higher than that of type 2 osteonecrosis of the femoral head (P ＜ 0.001),and the time to collapse was markedly shortened.None collapse occurred in all six hips with type Ⅰ osteonecrosis of the femoral head during follow-up.(4) In summary,preservation of anterolateral portion is associated with potential collapse progression in necrotic femoral head.

Percutaneous pulmonary puncture guided by computed tomography (CT) is one of the most effective tools for obtaining lung tissue and diagnosing lung cancer. Path planning is an important procedure to avoid puncture complications and reduce patient pain and puncture mortality. In this work, a path planning method for lung puncture is proposed based on multi-level constraints. A digital model of the chest is firstly established using patient's CT image. A Fibonacci lattice sampling is secondly conducted on an ideal sphere centered on the tumor lesion in order to obtain a set of candidate paths. Finally, by considering clinical puncture guidelines, an optimal path can be obtained by a proposed multi-level constraint strategy, which is combined with oriented bounding box tree (OBBTree) algorithm and Pareto optimization algorithm. Results of simulation experiments demonstrated the effectiveness of the proposed method, which has good performance for avoiding physical and physiological barriers. Hence, the method could be used as an aid for physicians to select the puncture path.

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.
