Objective This study is to discuss the effects of cognitive therapy on life quality of rural breast cancer patients during chemotherapy in order to offer evidence for choosing the appropriate therapeutic measures.Methods 120 rural breast cancer patients were equally divided into the intervention group and the control group at random.The usual care plus cognitive treatment was given to the patients in the intervention group for 6 months,while only the usual care after chemotherapy was given to the control group.The quality of life assessments were carried out to both groups on the 5th day during hospitalization,and the first,third and 6th month during recheck period of time,respectively.The treatment effect was observed.Results There were statistical significant difference of the total scire of life quality assessment on the 5th day,the first,third and 6th month,respectively,between the intervention group and the control one after cognitive intervention.The downtrend of total score of quality of life in the intervention group after cognitive intervention was more significant than the control group,which indicated the quality of life of the intervention group was better than the control group. Conclusions Cognitive therapy is an efficient method to enhance the quality of life of rural breast cancer patients during chemotherapy.

The HPLC fingerprint differences ofRadix Platycodonis from different origins were studied to provide references for their quality control and production. The total platycodins were purified by DB101 macroporous resin. HPLC-ELSD fingerprints of the total platycodins for 39 batches ofRadix Platycodonis samples from 9 provinces were performed on an Agilent HC-C8 column (4.6 mm x 250 mm, 5μm) with gradient elution. The mobile phase was acetonitrile-0.5% acetic acid. The injection volume was 6μL. The flow rate was 0.5 mL·min-1. The temperature of drift tube was set at 90℃. And the gas flow (N2) was set at 1.2 mL·min-1. The results showed that there were large differences in the quality ofRadix Platycodonis from different origins with the common fingerprints of 6 batches of samples fromChifeng in Inner Mongolia as references. The quality ofRadix Platycodonis was closely related to the seeds, the ecological environment, the way of drying and storing and so on. It was concluded that it was important to strengthen the provenance base construction, standardization of the seeds, reasonable formulation of the regionalization, and standardization of the production processing for the cultivation and production ofRadix Platycodonis.

This study was aimed to compare the expectorant and antitussive actions ofPlatycodon grandilforum from different production areas in order to provide references for its cultivation and production. The antitussive activities ofP. grandilforum water extract from different areas were investigated through testing the cough times induced by ammonium hydroxide in mice. And the expectorant activities were studied by testing the amount of tracheal phenolsulfonphthalein excretion in mice. The results showed that the minimum effective dose ofP. grandiflorum fromChifeng of Inner Mongolia was 0.2 g·kg-1. Under this dosage,P. grandiflorum fromChifeng of Inner Mongolia can significantly reduce the cough frequency in mice (P < 0.01), and significantly prolong the cough incubation period in mice (P < 0.01).P. grandiflorum fromSichuan province,Shangzhou ofShaanxi province andChongqing can significantly decrease the cough frequency in mice (P < 0.05). P. grandiflorum from Sichuan province,Shangzhou ofShaanxi province andChifeng of Inner Mongolia can significantly increase the phenolsulfonphthalein excretion quantity in mice (P < 0.05). It was concluded thatP. grandilforum was effective for relieving cough and removing sputum. The effect ofP. grandilforum fromChifeng of Inner Mongolia was obviously stronger than that from other areas.

Pancreatic fistula is a common and serious complication after pancreatic surgery. Pancreatic fistula, intra-abdominal infection and hemorrhage are known as the " lethal triad" after pancreatic surgery, which seriously affect the curative efficacy of operation. Although the incidence of pancreatic fistula has not been significantly reduced, there have been a large number of studies on the risk factors of pancreatic fistula and the means of prevention and therapy, which try to minimize the harm of pancreatic fistula. In this article we review the recent development of the latest definition, high risk factors and treatment of postoperative pancreatic fistula according to relevant literatures at home and abroad, aiming at summarizing the research advances on the therapy of pancreatic fistula after pancreatic surgery.

Objective:To investigate the effect of Chinese traditional medicine-Shuanghuangbu combined with Xipayi Mouth Rinse on the periodontal indexes of the peri-implantitis patients,and to detect the curative effect of Shuanghuangbu combined with Xipayi Mouth Rinse in the treatment of peri-implantitis.Methods: A total of 40 patients diagnosed as peri-implantitis were randomly divided into control group and Chinese traditional medicine group (n=20).All of the patients received supragingival scaling and subgingival scaling,and then the peri-implant pocket of the patients in Chinese traditional medicine group were washed with Xipayi Mouth Rinse,while the fine probe slided slowly along the inner wall of peri-implant pocket into the bottom and retained the Shuanghuangbu,and retreated gently and made the medicine overflow the gingival margin.The patients in control group were given 3% hydrogen peroxide and 0.9% sodium chloride injection washed by turns.The indexes of covering modified plaque index (mPLI),probing pocket depth (PPD),modified sulcular bleeding index (mSBI)of the patients in two groups at baseline and after treatment were detected;Whatman# 1 was applied to aspirate the peri-implant sulcus fluid (PISF)which were weighed at baseline and after treatment,and the level of interleukin-1β (IL-1β)in PISF was analyzed by ELISA method.Results:No differences were observed in age,sex,periodontal indexes, weights of PISF and IL-1βlevels of the patients in two groups before treatment (P >0.05).Compared with before treatment,the indexes including PPD,mSBI,mPLI,weight of PISF and IL-1βlevel in PISF of the patients in two groups were decreased after treatment (P < 0.05).After treatment,the differences in mSBI,mPLI,weight of PISF and IL-1β level in PISF of the patients between control group and Chinese traditional medicine group were significant (P <0.05).Compared with control group,the PPD level of the patients in Chinese traditional medicine group was decreased,but the difference was not significant (P >0.05).Conclusion:The curative effect of Chinese traditional medicine-Shuanghuangbu combined with Xipayi Mouth Rinse is obsious,and the treatment can improve the periodontal status and reduce the level of IL-1βin PISF.

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.

Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APC^min/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.
