ABSTRACT
Objective:To investigate the feasibility of individualized primary clinical target volume (CTV) delineation in intensity-modulated radiotherapy for nasopharyngeal carcinoma (NPC).Methods:Clinical data of 87 consecutive patients newly diagnosed with lateralized NPC in Jiangsu Cancer Hospital between October 2016 and February 2018 were retrospectively analyzed. Lateralized NPC is defined as tumor invasion not exceeding the contralateral wall. According to the tumor spread, the primary CTV was optimized as follows: CTV2 only covered the medial part of the contralateral pterygopalatine fossa, whereas the contralateral foramen oval was not included; on the level of parapharyngeal space, the contralateral side of CTV only covered the posterior lateral lymph nodes, whereas the contralateral internal jugular vein was not regularly covered. Failure patterns and 5-year survival [local control rate (LCR), progression-free survival (PFS) and overall survival (OS)] were evaluated by Kaplan-Meier method. Paired t-test and rank-sum test were used to analyze the dose variation in the optimized region and adverse reactions. Results:The median follow-up time was 59.5 months. The 5-year LCR, PFS, and OS were 98.9%, 86.5% and 92.1%, respectively. There was no local recurrence in the optimized area of CTV. Dosimetric comparison results showed that the doses of parotid gland, temporal lobe, cochlea and middle ear on the contralateral side were reduced by 13.45%, 9.14%, 38.83%, and 29.36%, respectively. Four cases (4.6%) developed grade 3 hearing loss, all on the ipsilateral side. The optimized scheme significantly alleviated the hearing loss on the contralateral side compared to that on the ipsilateral side ( P<0.001). Other grade 3 late adverse reactions included cranial nerve injury, subcutaneous fibrosis in the neck and visual impairment, with 1 case each. Conclusion:Individualized primary CTV for lateralized NPC is feasible and safe, with obvious dosimetric advantages and reduced adverse reaction rate, which is worthy of clinical promotion.
ABSTRACT
Primary lung cancer， as one of the most commonly diagnosed malignancies and the top leading cause of cancer death worldwide， has seriously endangered human life. In China， due to regional differences， although the impact of lung cancer on different regions is different， it still has the highest mortality among malignant tumors. Western medicine often has certain limitations in the treatment of lung cancer. At present， the combination of western medicine and traditional Chinese medicine （TCM） or the direct application of TCM has become an inevitable trend in the treatment of lung cancer. TCM treatment is guided by the holistic view， which includes the view of integration of the five internal organs and the integration of the body and spirit. Therefore， the treatment of lung cancer in TCM emphasizes that although the disease is located in one organ， the whole body should be treated， which corresponds to the theory of the view of integration of the five internal organs. In addition to the lung in the treatment of lung cancer， the spleen and kidney should also be treated. The lung， spleen， and kidney correspond to metal， earth， and water， respectively on the five elements. According to the generation relationship of the five elements， since earth generates metal and metal generates water， earth is the mother of metal and water is the child of metal. Therefore， benefiting fire （kidney） can replenish earth. Tonifying the mother and son of the lung can treat lung diseases， reflecting mutual generation and transformation and ceaseless generation and transformation. Long-term consumption of Qi by lung cancer can affect mother-organ. In the context of disorder of child-organ affecting mother-organ， mother-organ should be tonified in the face of deficiency. The treatment principle of banking up earth to generate metal should be followed to reinforce healthy Qi and treat the root. Effulgent earth can promote the generation of metal and the syndrome of lung deficiency can be resolve. The lung and kidney deficiency is an important factor in the incidence of lung cancer. Yin deficiency for a long time can hinder the generation of water by metal， resulting in failure of water in moistening metal， so both mother organ and child organ should be tonified. The treatment principle of mutual generation between metal and water should be employed to moisten the kidney and lung， thereby facilitating the vigorous ventilation and descending of the lung. The spleen is the mother organ of the lung， and the kidney is the child organ of the lung. Long-term lung cancer causes the deficiency of the mother and child organs， so the treatment principle of replenishing fire to nourish earth should be adopted to benefit the kidney and tonify the spleen. Therefore， innate basis and acquired foundation are both filled， and the lung can be regulated properly. When the lung， spleen， and kidney are harmonized， the generation and transformation of Qi and blood are active， and the Yin and Yang of Qi and blood are balanced， so the self-rehabilitation ability of the body is ensured， and the treatment of lung cancer will achieve a good curative effect. According to the holistic view of TCM， the whole body should be regulated to treat lung cancer. The lung， spleen， and kidney are all treated in the treatment of lung cancer. With the lung， spleen， and kidney as the central axis， the treatment principles of banking up earth to generate metal， replenishing fire to nourish earth， and mutual generation between metal and water should be followed in the treatment of lung cancer， and a good therapeutic effect can be achieved.
ABSTRACT
ObjectiveTo observe the effect of bilateral sequential repetitive transcranial magnetic stimulation on the motor function of upper limbs in stroke patients. MethodsFrom December, 2020 to December, 2022, 62 stroke inpatients in the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine were included. They were randomly divided into control group (n = 31) and observation group (n = 31). Both groups accepted conventional medicine and rehabilitation, as well as electroacupuncture antagonistic muscle therapy. Before electroacupuncture, the observation group acceped low-frequency repetitive transcranial magnetic stimulation at primary motor cortex (M1) on the healthy side, followed by intermittent theta burst stimulation at M1 on the affected side, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Barthel Index (MBI) and modified Ashworth Scale (MAS), and motor evoked potential (MEP) latency was compared before and after treatment. ResultsOne patient dropped down in the observation group, and no adverse event happened. After treatment, the scores of FMA-UE and MBI significantly increased (|t| > 9.953, P < 0.001), and the score of MAS and the latency of MEP significantly decreased (|t| > 5.043, P < 0.001) in both groups; while all of them were better in the observation group than in the control group (|t| > 2.237, P < 0.05). ConclusionBilateral sequential repetitive transcranial magnetic stimulation can effectively promote the recovery of upper limb motor function in stroke patients.
ABSTRACT
Objective@#To study the effects of atmospheric fine particulate pollution on the lung function of primary school students before and after heating during the winter in Zhengzhou.@*Methods@#In Zhengzhou, two areas with low and high level of PM 2.5 pollution(A and B), were selected as monitoring points from 2016 to 2018. Each monitoring station selected one elementary school within around 1 km and used a cluster random sampling method to extract students from grades 3 to 5 as the research subjects. Lung function tests were conducted before and after heating in winter, and mass concentration of PM 2.5 were recorded daily and compared to those recorded one month prior.@*Results@#The average daily mass concentration of PM 2.5 were 74 μg/m 3 and 92 μg/m 3 in the light pollution monitoring points A and the heavy pollution monitoring points B, which exceeded the standard for 97 and 126 days, respectively. The FVC and FEV1.0 indexes for the first test of male students before heating were higher than those for the second test from 2016-2018 (P<0.05). Except in 2016,the FVC and FEV1.0 indexes for the first test of female students were also higher than those for the second test (P<0.05). After stratified by sex,multivariate linear regression showed that PM 2.5 was associated with lung function as measured by the FEV1.0, PEF, FEF25 and FEF75 values of the students were negatively correlated (B=-0.13--0.07,-0.13--0.08,P<0.05).@*Conclusion@#Fine particulate air pollution before and after heating during the winter in Zhengzhou had different effects on the lung function of primary school students. Therefore, it is necessary to strengthen the respiratory health protection of primary school students in winter to protect their health.
ABSTRACT
Objective:Diabetic foot osteomyelitis (DFO) is not only a special and challenging problem in diabetic foot infection, but also an important reason for amputation and disability of patients with diabetic foot infection.The diagnosis of DFO usually requires the combination of information of medical history and physical examination, serum inflammatory markers and imaging findings.The results of bone tissue culture and bone histopathology are recognized as the gold standards for the diagnosis of DFO.At present, there is no optimal treatment plan and process for DFO.Comprehensive, individualized treatment and multidisciplinary cooperation should be given on the basis of full assessment to ensure the best treatment effect and improve the quality of life of patients with DFO.

ABSTRACT
Objective To investigate the expression of Focal adhesion kinase (FAK) and p53 in rheumatoid arthritis (RA) Fibroblast Like Synoviocytes and to explore the pathogenesis of RA.This study also studied the effect of FAK and p53 on the proliferation of Fibroblast Like Synoviocytes in RA on order to identify new target for the treatment of RA.Methods Synovial tissue from RA patients were cultured in vitro;FLS were cultured in TNF-α (10 ng/ml) and different density of protease inhibitor (MG-132) (1,5,10,20 μmol/L)for 48 h.Then the level of mRNA of both FAK and p53 in each group was tested by real time polymerase chain reaction (RT-PCR).FLS were cultured with different density of protease inhibitor (MG-132) (1,5,10,20μmol/L) for 24 h,48 h,72 h,96 h then the cell proliferation of each group were tested.ANOVA was used to compare the means between groups.Results ① After TNF-α stimulating,the level of FAK mRNA was higher than the control group [(1.48±0.09 vs(1.03±0.33),F=7.807,P＜0.05).Compared with the control group,the level of p53 mRNA decreased [(0.97:±0.03) vs (1.30±0.39),F=19.933,P＞0.05).② After stimulated with different density of MG-132,the level of p53 mRNA was higher than the control group [(3.12±0.72) vs (1.30±0.39),F=19.933,P＜0.05),and the 5μ mol/L group was the highest of them.Compared with the control group,the level of FAK mRNA decreased [(0.93±0.20) vs (1.03±0.33),F=7.807,P＞0.05).③ After stimulated with different density of MG-132,the proliferation of FLS was slower than the control group (24 h F=16.654,P＜0.05;48 hF=13.652,P＜0.05;72 h F=72.999,P＜0.05;96 h F=51.533,P＜0.05).Conclusion In vitro,after stimulated with TNF-α,the level of mRNA of Focal adhesion kinase is increased,while the level of that decreases after MG-132 stimulation.Focal adhesion kinase is involved in the pathogenesis of rheumatoid arthritis.In vitro,after MG-132 stimulating,the level of mRNA of p53 is increased.p53 inhibits the excessive proliferation of RA synovial fibroblast cells and plays an important role in the pathogenesis of rheumatoid arthritis.
ABSTRACT
Objective:To investigate the incidence rate and risk factors of acute kidney injury (AKI) after off-pump coronary artery bypass grafting (CABG),and to compare the effects of AKI on complications after operation and major adverse cardiovascular and cerebrovascular events (MACCE) after 3 years' follow-up.Methods:In the study,299 consecutive patients who underwent scheduled off-pump CABG from January 2010 to March 2012 were included.The patients were divided into AKI group with AKI and control group without AKI after operation.The data during perioperative stage were compared,and multivariable Logistic regression modeling was used to identify the risk factors of AKI.The complications were compared after surgery and the patients were followed up for 3 years to observe the difference of MACCE between the two groups.Results:AKI occurred in 37.1％ patients (111/299).The elevated serum creatinine levels (Wald =9.276,P =0.002,95 ％ CI 1.006-1.028),chronic obstructive pulmonary disease(COPD) (Wald =3.469,P =0.063,95％ CI 0.950-7.630),decreased left ventricular ejection fraction (LVEF) (Wald =4.414,P =0.036,95 ％ CI 0.965-0.999),and implantation of intraaortic balloon pump (IABP) before or after operation(Wald =6.745,P =0.009,95％ CI 1.336-7.925)were risk factors of AKI in multivariable logistic regression modeling.More complications occurred in AKI group,such as the duration of mechanic ventilation,the time of ICU and the length of stay post operation,reintubation,pulmonary infection,stroke,hemorrhage of digestive tract,the volume of blood transfusion (plasma and red blood cell) and renal replacement therapy(P ＜ 0.05).The difference of mortality rate had no statistical significance between the AKI group and the control group,but two patients died in the AKI group.The difference of MACCE between the two groups had no statistical significance after 3 years' follow-up either.Conclusion:The incidence of AKI was high (37.1％) after off-pump CABG.The elevated serum creatinine levels,COPD,decreased LVEF,and implantation IABP before or after operation were independent risk factors of AKI in multivariable Logistic regression modeling.More complications occurred in AKI group during perioperative period,but the difference of MACCE between the two groups after 3 years' follow-up had no statistical significance.
ABSTRACT
The American Association for the Study of Liver Diseases (AASLD) updated and published the Practice Guidance for the Diagnosis and Management of Nonalcoholic Fatty Liver Disease (NAFLD) in July 2017, which provides recommendations for the accurate diagnosis, treatment, and effective prevention of NAFLD. Related metabolic diseases should be considered during the initial evaluation of patients suspected of NAFLD. Noninvasive diagnostic techniques including transient elastography, magnetic resonance elastography, and serum biochemical models should be used to evaluate the development and progression of liver fibrosis in patients with NAFLD. Clinical liver pathology report should clearly differentiate between nonalcoholic fatty liver (NAFL), NAFL with inflammation, and nonalcoholic steatohepatitis (NASH) and identify the presence or absence of liver fibrosis and its degree. Early medication for NAFLD can only be used in patients with pathologically confirmed NASH and liver fibrosis, and it is not recommended to use pioglitazone and vitamin E as the first-line drugs for patients with NASH which has not been proven by biopsy or non-diabetic NASH patients. Foregut bariatric surgery can be considered for obese patients with NAFLD/NASH who meet related indications. It is emphasized that the risk factors for cardiovascular disease should be eliminated for NAFLD patients. Statins can be used for the treatment of dyslipidemia in patients with NAFLD/NASH, but they cannot be used in patients with decompensated liver cirrhosis. Routine screening or hepatocellular carcinoma surveillance is not recommended for NASH patients without liver cirrhosis. Cardiovascular disease should be taken seriously during liver transplantation evaluation. There is still no adequate clinical evidence for the treatment of NAFLD in children and adolescents, and intensive lifestyle intervention is recommended as the first-line therapy for such patients.
ABSTRACT
Objective@#To analyze the genome characteristics of an avian influenza A (H9N2) virus isolated from an 11-month-old infant, and to look for possible sources of infection.@*Methods@#Throat swabs were collected from an infant with influenza-like illness in influenza sentinel surveillance hospitals and isolated for influenza viruses using cells. The isolates were identified for influenza virus types and subtypes by the method of hemagglutination assay, hemagglutination inhibition assay and fluorescence PCR. Whole genome sequencing of the isolated virus was carried out. The genome nucleic acid sequences and the deduced amino acid sequences were analyzed by comparing the phylogenetic trees which were constructed by bioinformatics software.@*Results@#A seasonal un-typed influenza virus was isolated from the infant with influenza like illness. With fluorescent PCR method , it was identified as H9N2 subtype of avian influenza virus and the case was confirmed as a human infected with an avian influenza A(H9N2) virus. Epidemiological studies revealed that the case had no clear history of poultry contact and exposure. Blast analysis shows that eight segments of the viral genome are avian origin, and 97.5%-99.8% homology with that of viruses isolated from the live-poultry markets. The virus belongs to G57 genotype, deduced amino acid sequence analysis shows that the virus has typical low pathogenic avian influenza characteristics.@*Conclusions@#Although the case does not have a clear history of contact or exposure to poultry, molecular traceability suggests that possible sources of infection may be still from poultry.
ABSTRACT
Objective This study was to understand the structure characteristics of prophages in the genome of Enterococcus hirae R17,and also to analyze their interaction relationships with the host bacterium.Methods The gene distribution and gene encoding characteristics of prophages in the genome of Enterococcus hirae R17 were identified using the PHAST software.The virulence gene,antimicrobial resistance genes,and environmental resistance genes in the prophages were also analyzed.Results Three prophages were found on the chromosome of Enterococcus hirae,including two incomplete prophage elements (Prophage-1 and Prophage-2) and one complete prophage (Prophage-3).Some function genes of bacteria were found in the sequence of three prophages,including nucleotide transportation and metabolism related genes.One incomplete prophage carrying erythromycin-and bacitracin-resistance genes was identified in the plasmid,which suggested that prophage induced gene horizontal transfer caused erythromycin-and bacitracin-resistance of Enterococcus hirae R17.Conclusion This study laid a solid foundation for the diversity analysis of prophages of Enterococcus hirae.Prophages played an important role in promotion of antimicrobial resistance of enterococci.Scientists should pay more attention to the spread of antimicrobial resistance and pathogenicity induced by prophages.

The influence on blood pressure, heart rate, electrocardiogram, breathing flow and frequency in anesthetic dogs were observed. Results Three dosages of AWFD had no obvious influence on spontaneous activity and coordinated movement in mice, and had no evidently influence on sleep number and duration, but the high dosage group of AWFD had influence on sleep latency (P<0.01). AWFD had no impact on blood pressure, heart rate, electrocardiogram, breathing flow and frequency in anesthetic dogs. Conclusion AWFD has no evident effects on cardiovascular system and respiratory system in laboratory animal, however, the impact on the central nervous system remains to be further verified.
ABSTRACT
Objective The toxicological compatibility of Aconiti Carmichaeli Radix, as a toxic Chinese medicinal herb, combined with the other ingredients in Sini Decoction was investigated to elucidate the rationality of the combination of the ingredients in Sini Decoction from toxicological point of view. Methods Three kinds of experiments, acute toxicity in mice, heart toxicity in rats and aconitines level in water extract of Sini Decoction and its ingredients including Aconiti Carmichaeli Radix alone and its combination with licorice or dried ginger were adopted in this study. In the toxicological experiments, LD50 values for the acute toxicity test and TD50 values for the heart toxicity (arrhythemia as a parameter) of Sini Decoction, Aconiti Carmichaeli Radix alone and its combination with licorice or dried ginger were comparatively determined. And levels of individual aconitines of the water extracts from Sini Decoction, Aconiti Carmichaeli Radix alone and its combination with licorice or dried ginger were measured, respectively. Results The LD50 and TD50 of the combination of Aconiti Carmichaeli Radix and licorice in Sini Decoction were found to be higher than Aconiti Carmichaeli Radix alone or Sini Decoction, while the LD50 and TD50 of the combination of Aconiti Carmichaeli Radix and dried ginger appeared to be not different from those of Aconiti Carmichaeli Radix alone. The level of the main toxic compound of the water extracts for the combination of Aconiti Carmichaeli Radix and licorice, and Sini Decoction was lower than that of Aconiti Carmichaeli Radix alone and its combination with dried ginger. Conclusion The combination of Aconiti Carmichaeli Radix and licorice can attenuate the toxicity of Aconiti Carmichaeli Radix.
