This paper summarized Professor LI Yueqing's clinical experience in treating prostate cancer by stages from the perspective of deficiency and stasis. It is believed that the onset of prostate cancer is due to kidney deficiency， while blood stasis is the core pathogenesis， and dampness-heat， phlegm-turbid， and cancer toxins are the key pathological factors in the progression of the disease. The pathogenesis in the early stage of the disease is kidney qi depletion and dampness， heat and phlegm coagulation； in the middle stage， it is spleen and kidney depletion， phlegm coagulation and blood stasis； and in the late stage， the pathogenesis changes into yin deficiency and essence depletion， and stasis-turbid toxin obstruction. For treatment， the basic principle is to supplement and boost kidney qi， enrich and nourish the kidney yin. The main treatment methods are draining dampness， dissolving phlegm， dispelling stasis， clearing heat and resolving toxins， and the method of invigorating blood and dispelling stasis runs through the whole course of treatment. In the early stage， radical treatment is mainly used， and Longshe Yangquan Decoction （龙蛇羊泉汤） with modifications is supplemented to clear and drain dampness and heat. In the middle stage， androgen deprivation therapy is the basic treatment， and Bushen Tongqiao Decoction （补肾通窍汤） with modifications is used in combination to nourish the spleen and kidney， dissolve phlegm and dispel stasis. In the late stage， Dabuyin Pills and Liuwei Dihuang Pills （大补阴丸合六味地黄丸） with modifications is mainly used to enrich yin and supplement essence， resolve toxins and dissolve stasis， and prevent cancer recurrence.

Objective To propose a CT truncated data reconstruction model(DDTrans)based on projection and image dual-domain Transformer coupled feature learning for reducing truncation artifacts and image structure distortion caused by insufficient field of view(FOV)in CT scanning.Methods Transformer was adopted to build projection domain and image domain restoration models,and the long-range dependency modeling capability of the Transformer attention module was used to capture global structural features to restore the projection data information and enhance the reconstructed images.We constructed a differentiable Radon back-projection operator layer between the projection domain and image domain networks to enable end-to-end training of DDTrans.Projection consistency loss was introduced to constrain the image forward-projection results to further improve the accuracy of image reconstruction.Results The experimental results with Mayo simulation data showed that for both partial truncation and interior scanning data,the proposed DDTrans method showed better performance than the comparison algorithms in removing truncation artifacts at the edges and restoring the external information of the FOV.Conclusion The DDTrans method can effectively remove CT truncation artifacts to ensure accurate reconstruction of the data within the FOV and achieve approximate reconstruction of data outside the FOV.

Cuproptosis is a new type of cell death that depends on intracellular copper accumulation to trigger the aggregation of mitochondrial lipoacylated protein and the degradation of iron-sulfur cluster protein,with a different mechanism of action from autophagy,ferroptosis,pyroptosis,and necroptosis.Cuproptosis is closely association with the development of liver cancer and resistance to antitumor drugs,as well as the progression of various liver diseases such as hereditary liver diseases,nonalcoholic fatty liver disease,viral hepatitis,and liver cirrhosis.This article summarizes the mechanism of cuproptosis and its role in liver diseases,in order to provide a reference for further research and treatment of liver diseases.

Objective:To explore the effects of type D personality on mild cognitive dysfunction (MCI) in patients with coronary heart disease and the multiple mediating roles of dietary inflammation index (DII) and systemic immune inflammation index (SII) between type D personality and MCI.Methods:A cross-sectional study was used. A total of 321 patients diagnosed with coronary heart disease by coronary angiography in the Second Affiliated Hospital of Harbin Medical University from May 2022 to March 2023 were selected as the study objects by convenient sampling method. General Information Questionnaire, Type-D Personality Scale-14, Montreal Cognitive Assessment, and Semi-Quantitative Food Frequency Questionnaire were employed for data collection. DII and SII were used to evaluate dietary inflammatory potential and systemic inflammatory status, respectively. Structural equation modeling was utilized to analyze the mediating effectsamong type D personality, DII, SII and MCI.Results:A total of 306 valid questionnaires were collected. Among the 306 patients, there were 215 males (70.3%) and 91 females (29.7%), aged 27-70 (59.24 ± 9.16) years old. The structural equation model showed that type D personality could directly influence MCI (effect size = - 1.098, 95% CI - 1.869 - - 0.327), and could also mediate the occurrence of MCI in coronary heart disease patients through the single mediation of DII (effect size = - 0.374, 95% CI - 0.644 - - 0.128) and SII (effect size = - 0.450, 95% CI - 0.806 - - 0.132), as well as the chain mediation of DII and SII (effect size = - 0.146, 95% CI - 0.293 - - 0.027). Conclusions:Type D personality, DII and SII can affect the occurrence of MCI in CHD patients, and DII and SII play multiple mediating roles between type D personality and MCI in patients with coronary heart disease. Clinical and community nurses can improve the unhealthy dietary behavior, reduce the level of inflammation and delay the occurrence and development of MCI by early screening of type D personality in patients with coronary heart disease.

Klebsiella pneumoniae(KPn),as a conditioned pathogen that causes calf pneumonia,has caused serious harm to cattle industry,but the harm of Klebsiella pneumoniae to calves in Xin-jiang region is still unclear.In this study,to investigate the prevalence of KPn,its harm and some biological characteristics of pneumonia calves in Xinjiang,nasal swabs of pneumonia calves in some areas were collected aseptically,KPn isolation and identification were performed by routine meth-od,and 16S rDNA sequence evolutionary tree analysis was performed.The drug resistance was de-tected by K-B method,and a strain carrying multiple virulence was selected for mice median lethal dose test.The serotype,virulence gene and drug resistance gene of the strain were detected by PCR.The results showed that the detection rate of Klebsiella pneumoniae in nasal swabs of 218 pneumonia calves from Aksu,Changji and Yili regions of Xinjiang was as follows:14.68％(32/218),including 28.33％(17/60)in Aksu Prefecture,24.00％(6/25)in Changji Prefecture and 6.77％(9/133)in Yili Prefecture,they were divided into two serotypes,namely K1(7/32)and K5(5/32).A total of 13 KPn virulence genes were detected,mainly mrkD,ureA,wabG,uge and en-tB.LD50 was 2.38X 107cfu/mL.Drug susceptibility test and drug resistance gene detection showed that the isolated strain showed multiple drug resistance,and the resistance genes mainly carried blasHv and floR.16S rDNA sequence evolutionary tree results showed that the isolated strain had high homology with the isolates from Italy,Beijing and Shanghai of China.The detection rate of KPn in nasal swabs of pneumonia calves in Xinjiang region is high.The dominant serotypes are K1 and K5.The isolates carry a variety of virulence genes and have strong virulence.All of them are KPn strains producing ESBLs,suggesting that Klebsiella pneumoniae in Xinjiang region of China have a certain potential harm to calves.

Bronchiectasis is a complex and heterogeneous group of diseases with their own characteristics in terms of etiology, symptoms, infections and inflammation, among which infections are both the most common cause of bronchiectasis and the most important factor contributing to the progression of the disease and affecting the prognosis. The current paper will focus on the characterization, diagnosis and treatment of pathogenic bacteria in bronchiectasis.

Unlike healthy, non-transformed cells, the proteostasis network of cancer cells is taxed to produce proteins involved in tumor development. Cancer cells have a higher dependency on molecular chaperones to maintain proteostasis. The chaperonin T-complex protein ring complex (TRiC) contains eight paralogous subunits (CCT1-8), and assists the folding of as many as 10% of cytosolic proteome. TRiC is essential for the progression of some cancers, but the roles of TRiC subunits in osteosarcoma remain to be explored. Here, we show that CCT4/TRiC is significantly correlated in human osteosarcoma, and plays a critical role in osteosarcoma cell survival. We identify a compound anticarin-β that can specifically bind to and inhibit CCT4. Anticarin-β shows higher selectivity in cancer cells than in normal cells. Mechanistically, anticarin-β potently impedes CCT4-mediated STAT3 maturation. Anticarin-β displays remarkable antitumor efficacy in orthotopic and patient-derived xenograft models of osteosarcoma. Collectively, our data uncover a key role of CCT4 in osteosarcoma, and propose a promising treatment strategy for osteosarcoma by disrupting CCT4 and proteostasis.

Objective:To explore the influence of storage and delivery conditions of the peripheral blood samples from patients with chronic myeloid leukemia (CML) on the real-time quantitative PCR (RQ-PCR) detection of the BCR-ABL (P210) transcript levels.Methods:The peripheral blood samples of 84 CML patients were collected. The same sample was divided into different groups according to storage time (0, 6, 12, 24, 48, and 72 h) , temperature (room temperature, 18-24 ℃; low temperature, 2-8 ℃) , and vibration conditions (3, 6, and 12 h) . RQ-PCR was used to detect BCR-ABL (P210) transcript levels of the different groups. This study logarithmically transformed (log 10N) the original data [BCR-ABL copy number, ABL copy number, and BCR-ABL (P210) transcript levels]. Results:①Agarose gel electrophoresis showed significant RNA degradation of samples after storage for 48 and 72 h at room temperature. ②Among the overall samples, the BCR-ABL copy number of the samples stored at room temperature for 48 and 72 h was significantly lower than that of the samples stored at low temperature ( P<0.05) . However, the BCR-ABL (P210) transcript levels had no significant difference between samples stored at low temperature and room temperature. ③No significant changes were noted in the BCR-ABL (P210) transcript levels at different storage times (6, 12, 24, 48, and 72 h) regardless of storage temperature ( P>0.05) compared with that at baseline (0 h, -0.56±1.51) . ④ The BCR-ABL copy number of the overall sample only decreased significantly ( P<0.05) at 48 h (2.93±1.59) and 72 h (2.79±1.42) compared with that at baseline (0 h, 3.35±1.60) when stored at room temperature. The ABL copy number in the overall sample decreased significantly at 48 and 72 h (whether low and room temperature; P<0.05) . However, no significant changes were noted in the BCR-ABL (P210) transcript levels after vibration for 3 h (-1.29±1.81) , 6 h (-1.24±1.72) , and 12 h (-1.18±1.68; P>0.05) compared with that at baseline (0 h, -0.60±1.37) . Conclusion:Sample storage time, storage temperature, and vibration can interfere with the results of BCR-ABL and ABL copy number but have no significant effect on the quantitative determination of BCR-ABL (P210) transcript levels. This study provides strong support for the feasibility of transregional transportation of peripheral blood samples from patients with CML.

Objective:To explore the efficacy of neurolysis or nerve grafting in the treatment of the conducting neuroma of Narakas II obstetric brachial plexus palsy (OBPP), and provide the reference basis for choosing an optimal method.Methods:From January, 2009 to December, 2014, 32 patients undergoing surgical treatment due to Narakas II OBPP were included in this study. Neurolysis was performed in 15 patients, and the procedure of nerve grafting was performed in 17 patients. The general information included gender, age, birth weight, injury cause, etc. were recorded and compared to each other between 2 groups. A followed-up study had been conducting after surgery, the functional rating systems of Gilbert and Raimondi were used for quantitative comparison between preoperative function and postoperative function of shoulder joint, elbow joint and hand. In addition, the differences of the measurement data were compared with the single factor analysis of variance and paired t-test by using SPSS 22.0 statistical software. When P<0.05, it was considered statistically significant. Results:There was no statistically significant difference in the baseline information between 2 groups ( P>0.05). The average time of follow-up was 58.44 (48-96) months. And the fourth year' average score of shoulder joint, elbow joint, hand of the neurolysis group improved from preoperative (1.07±0.85) , (2.07±0.77) and (3.47±0.62) score to (3.00±0.73), (4.13±0.62) and (4.53±0.72) score ( P<0.05), and the nerve grafting group rose from an average of (0.76±0.73), (1.71±0.46) and (3.71±0.67) score to (3.24±0.55), (4.29±0.46) and (4.65±0.48) score ( P<0.05). But the different score between 2 groups was no statistically significant ( P>0.05), respectively. In addition, the proportion of the patients who needed the secondary operation about functional reconstruction in the neurolysis group and the nerve grafting group was 73.33% and 35.29% respectively, besides the proportion of the shoulder joint and elbow joint in the surgical sites accounted for 82.35%, 17.65% respectively. Conclusion:Nerve grafting is a better choice for the treatment of conducting neuroma of Narakas II OBPP at present.
