Objective: To observe the therapeutic effects of needle warming moxibustion for chronic diarrhea. Methods: Two-hundred cases with chronic diarrhea were divided randomly into a treatment group and a control group. 100 cases in the treatment group were treated with needle warming moxibustion on specific acupoints. 100 cases in the control group were treated by oral administration of Smecta. Results: The therapeutic results showed cure in 52 cases, remarkable effect in 34 cases, improvement in 14 cases and the total effective rate in 100.0% in the treatment group, and cure in 5 cases, remarkable effect in 23 cases, improvement in 33 cases, failure in 39 cases and the total effective rate in 61.0% in the control group. The comparison of the total effective rate between the two groups was statistically significant (P<0.05). Conclusion: The needle warming moxibustion on specific acupoints is better than oral administration of Smecta in the therapeutic effects.

Objective To assess the role of promyelocytic leukemia protein (PML)and P53 in the progression of esophageal squamous cell carcinoma(ESCC)and its precursor lesions. Methods Different expression patterns of PML and P53 of 241 cases of ESCC combined with adjacent precursors were analyzed by tissue array and immunohistochemistry and correlated with clinicopathological parameters. Results In ESCC and its precursor lesions, PML and P53 displayed positive or strong positive, while in normal esophageal epithelia, these proteins showednegative or stained positive only in parabasal cell layer. The expression level of PML was correlated with the depth of invasion of esophageal carcinomas (X2=29.461,P<0.001),lymph metastasis status(X2=15.226,P<0.001)and pTNMs(x2=26.956,P

Objective To explore the effects of silencing H2AX gene on esophageal cancer ECA109 cell xenograft growth and sensitivity to radiotherapy in nude mice.Methods BALB/c nude mice models were established by subcutaneously inoculating differently treated ECA109 cells into nude mice.By random number table method 60 nude mice were divided into six groups,including blank group,irradiation group,negative group,negative with irradiation group,silence group and silence with irradiation group.The nude mice were irradiated with 15 Gy of 6 MV X-rays 21 d after inoculation.After irradiation 48 h,half of each mice group was terminated.The tumor specimens were processed by Western blot,RT-PCR and flow cytometry were used to detect the change in protein levels,RNA levels,and cell cycle.Results The tumor volume was (42.76 ±4.40) mm3 in silence group,significantly smaller than that of the blank group (73.18±8.80) mm3 and the negative group(71.27 ±8.40) mm3(F=67.8,P＜0.01).H2AX protein expression level in the silence group was also significantly lower (0.12 ±0.03 vs.1.12 ±0.11,1.16 ± 0.08,F =34.27,P ＜ 0.01).Relative H2AX mRNA expression level in the silence group was (0.85 ± 0.31),significantly lower than that of the blank group (1.86 ± 0.26) and the negative group (1.82 ±0.24,F =39.45,P ＜ 0.01).Co-immunoprecipitation assay showed that γ-H2AX and MDC1,53BP1 obvious interaction after irradiation,which would be weakened through silencing H2AX.The tumor volumes at different groups had significant difference after irradiation (F =13.56,P ＜ 0.01).The apoptosis rate in the silence group was significantly higher than that of the blank group and the negative group [(24.15±2.25) ％ vs.(13.26±1.54) ％,(12.78±1.47) ％ (F=54.33,P＜0.01)].G2/M phase arrested in the silence with irradiation group lower than that of the radiation group (F =10.21,P ＜ 0.01).Conclusions Silencing H2AX gene expression could inhibit the growth of esophageal cancer ECA109 cell xenograft and increase the radiosensitivity of tumor.

Objective To observe the occurrence and risk factors of arrhythmia in chronic kidney disease (CKD) patients in different stages of renal function. Methods A total of 405 CKD patients were enrolled in this study and none of them received renal replacement therapy.The 24 h dynamic electrocardiogram (DCG) was performed,and baseline characteristics were compared.Multivariable Logistic regression analysis was used to examine the relationship between the severe arrhythmia and the potential risk factors,such as age,gender,CKD stage,diabetes,hypertension,hyperpotassaemia,left ventricular hypertrophy (LVH),etc. Results There were 69 patients (17.04％),79 patients (19.51％),82 patients (20.25％),88 patients (21.73 ％) and 87 patients (21.48％) in CKD stage 1,2,3,4 and 5,respectively.As high as 45.68％ of all the patients had severe arrhythmia,represented by 27.54％,29.11％,42.68％,57.95％ and 65.52％ in CKD stages 1-5 respectively.The occurrence of severe arrhythmia increased as the eGFR decreased in CKD stages 2,3,4 (p＜0.05).On multivariable Logistic regression analysis,the occurrence of severe arrhythmia was related to LVH,CKD stage,diaberes hyertension and hyperpotassaemia are signidicantly assoxiated with severe arrhythmia.

Objective To explore the clinical characteristics and risk factors of occult pneumonia in advanced elderly patients.Methods A total of 170 advanced elderly patients with community-acquired pulmonary infection in geriatric department of Xijing hospital from January 2014 to October 2017 were enrolled.Patients were divided into two groups:the observation group (with occult pneumonia,n=80)and the control group(without occult pneumonia,n =90).Clinical data of patients were collected,and clinical characteristics and related risk factors of occult pneumonia in elderly patients were analyzed.Results There was no statistically significant difference in the positive rate of sputum culture and the distribution of pathogenic bacteria between the two groups (P ＞ 0.05).Gram-negative bacteria predominated in pathogenic bacteria.The hospitalization time was longer in the observation group than in the control group[(17.3 ± 3.0) d vs.(10.3 ± 3.9) d,P ＜ 0.05].The mortality rate was higher in the observation group than in the control group(10.0 ％ vs.3.3 ％,P ＜ 0.05).The age was older in the observation group than in the control group[(87.0± 1.7) years vs.(82.0± 2.4) years,P ＜ 0.05].The incidences of diabetes,Alzheimer's disease,hypothyroidism and long-term bed rest were higher in the observation group than in the control group (P ＜ 0.05).Multivariate logistic regression analysis showed that age (OR =6.93),dementia (OR =4.32),hypothyroidism(OR =4.89) were independent risk factors for occult pneumonia (P ＜ 0.05).Conclusions The pathogenic bacteria in advanced elderly patients with occult pneumonia are mainly gram-negative bacteria.The positive rate of CT scan confirmed-occult pneumonia is much higher than that by chest X-ray.The advanced elderly patients with occult pneumonia have longer hospitalization time and higher mortality rates.Old age,senile dementia and hypothyroidism are independent risk factors for occult pneumonia in advanced elderly patients.

Objective To explore the correlation between the immune related adverse （irAEs） reactions in patients treated with pembrolizumab and traditional Chinese Medicine （TCM） constitution. Methods A total of 110 patients diagnosed with non-small cell lung cancer for the first time were selected. When receiving pembrolizumab immunotherapy for the first time, a general information questionnaire, a TCM constitution classification and judgment scale, an immune related adverse reaction follow-up record book, and a patient's self-perception diary were used to investigate and analyze the TCM syndrome and adverse reactions of the patients. Results Among non-small cell lung cancer patients, there were more than four TCM constitutions, with 48 cases （43.64%） having a calm constitution, 20 cases （18.18%） having a biased constitution, 30 cases （27.27%） having a yang deficiency constitution, and 12 cases （10.91%） having a yin deficiency constitution. Qi deficiency and Yang deficiency were more prone to fatigue, while Yang deficiency was more prone to rash; Qi deficiency and Yin deficiency were more prone to itching; Yang deficiency was more prone to diarrhea; Non-small cell lung cancer patients with mild constitution were less prone to immune related adverse reactions. Conclusion TCM constitution is related to irAEs, which could predict the occurrence of immune related adverse reactions from the perspective of TCM constitution and intervene in adverse reactions early.
