The mammalian target of rapamycin (mTOR) pathway is abnormally activated in lung cancer. However, the anti-lung cancer effect of mTOR inhibitors as monotherapy is modest. Here, we identified that ginsenoside Rh2, an active component of Panax ginseng C. A. Mey., enhanced the anti-cancer effect of the mTOR inhibitor everolimus both in vitro and in vivo. Moreover, ginsenoside Rh2 alleviated the hepatic fat accumulation caused by everolimus in xenograft nude mice models. The combination of everolimus and ginsenoside Rh2 (labeled Eve-Rh2) induced caspase-independent cell death and cytoplasmic vacuolation in lung cancer cells, indicating that Eve-Rh2 prevented tumor progression by triggering paraptosis. Eve-Rh2 up-regulated the expression of c-MYC in cancer cells as well as tumor tissues. The increased c-MYC mediated the accumulation of tribbles homolog 3 (TRIB3)/P62⁺ aggresomes and consequently triggered paraptosis, bypassing the classical c-MYC/MAX pathway. Our study offers a potential effective and safe strategy for the treatment of lung cancer. Moreover, we have identified a new mechanism of TRIB3/P62⁺ aggresomes-triggered paraptosis and revealed a unique function of c-MYC.

Objective:To evaluate clinical efficacy and safety of topical compound oleum lithospermi in the treatment of mild to moderate diaper dermatitis.Methods:A multicenter, randomized, positive-drug parallel-controlled clinical trial was conducted in 19 hospitals from July 2019 to August 2020. Children aged 0 - 12 months with mild to moderate diaper dermatitis were enrolled and randomly divided into 2 groups using a random number table: test group topically treated with compound oleum lithospermi, and control group topically treated with zinc oxide cream. The treatment was carried out 6 - 8 times a day for 7 days. Visits were scheduled on days 0 and 7, and total response rate and clinical healing time were evaluated. Changes in the dermatitis family impact (DFI) score were compared between the test group and control group, and adverse events were recorded. Statistical analysis was carried out by using independent-sample t test for normally distributed continuous data, Wilcoxon rank sum test for non-normally distributed continuous data, and chi-square test or Fisher′s exact test for unordered categorical data; survival curves were drawn, and log-rank test was used for comparisons between two groups. Results:A total of 343 children with diaper dermatitis were enrolled in this study. Among them, 31 children violated the protocol, so 312 were included in the per protocol set, including 157 in the test group and 155 in the control group, and all completed the visits on days 0 and 7. The total response rate was significantly higher in the test group (87.26%, 137/157) than in the control group (78.71%, 122/155; χ2 = 4.04, P = 0.044) . The clinical healing time was significantly shorter in the test group (5.33 days) than in the control group (6.13 days; χ2 = 4.67, P = 0.025) . After 7-day treatment, the DFI score significantly decreased in both the 2 groups compared with that before the treatment, but there was no significant difference in the DFI score between the 2 groups (test group: 4.02 ± 6.96, control group: 3.58 ± 5.90, Z = -0.39, P = 0.686) . The incidence of adverse events was 2.92% (5/171) and 5.45% (9/165) in the test group and control group respectively, and there was no significant difference between the 2 groups ( χ2 = 0.03, P = 0.865) . Conclusion:Compound oleum lithospermi can markedly reduce the clinical severity of diaper dermatitis, improve the total response rate, shorten the clinical treatment period, and improve the quality of life of children′s families with a favorable safety profile.

External apical root resorption is among the most common risks of orthodontic treatment, and it cannot be completely avoided and predicted. Risk factors causing orthodontic root resorption can generally be divided into patient- and treatment-related factors. Root resorption that occurs during orthodontic treatment is usually detected by radiographical examination. Mild or moderate root absorption usually does no obvious harm, but close attention is required. When severe root resorption occurs, it is generally recommended to suspend the treatment for 3 months for the cementum to be restored. To unify the risk factors of orthodontic root resorption and its clinical suggestions, we summarized the theoretical knowledge and clinical experience of more than 20 authoritative experts in orthodontics and related fields in China. After discussion and summarization, this consensus was made to provide reference for orthodontic clinical practice.

Objective:To analyze the mediating role of self-esteem and control sources in readmission frequency and self-perceived burden of elderly patients with chronic heart failure(CHF).Methods:A total of 346 cases of elderly patients with CHF were included, using self-perceived burden scale(SPBS), self-esteem scale(SES) and multidimensional health locus of control scale(MHLC) to investigate.SPSS 20.0 software was employed to coduct Pearson and Spearman correlation analysis and multiple linear stepwise regression to construct the structural equation model.Process 2.13.2 plug-in was used to test the intermediate effect of Bootstrap.AMOS 23.0 was used for structural equation model and path analysis verification.Results:(1) The readmission frequency during the recent years of the elderly patients with CHF was 0-8, and M( P25, P75) was 1(1, 3). The mean score of self-esteem scale was (29.25±3.67), and the score of internal control in psychological control source was (22.67±3.85). The score of influential others was (26.45±3.38). The opportunity score was (19.84±3.82). The mean SPBS score was (22.19±9.49). (2) SPBS total score was significantly negatively correlated with self-esteem ( r=-0.359, P<0.01), positively correlated with opportunity control source ( r=0.169, P<0.01). Self-esteem was positively correlated with internal control( r=0.237, P<0.01), control of influential others( r=0.225, P<0.01). The readmission frequencies of CHF were significantly negatively correlated with self-esteem( r=-0.119, P<0.05) and internal control( r=-0.173, P<0.01), positively correlated with SPBS( r=0.219, P<0.01). (3) Multiple regression and structural equation model results showed that readmission, self-esteem and psychological control sources could account for 18.0% of the total variables of self-perceived burden.The relationship between readmission and self-perceived burden was mediated by self-esteem and locus of control, accounting for 20.00% of the total effect. Conclusion:Self-esteem and control sources are partially mediating the effect between readmission and self-perceived burden.By nursing intervention to improve the self-esteem level, positive coping strategies of internal control of elderly patients with CHF, the burden of self-perception may possibly be alleviated.

Objective To culture and identify corneal fibroblasts from human keratoconus patients (HKCs).Methods HKCs and corneal fibroblasts from human healthy controls (HCFs) were cultured by tissue block adherence method.Cellular morphology and ultrastructure were observed by inverted phase contrast microscope and electron microscopy respectively.Cell viability was detected by cell counting kit-8 (CCK-8) assay.α-Smooth muscle actin (αt-SMA),collagen type 1 alpha 1 (COL1A1) and collagen type 3 alpha 1 (COL3A1) protein expression levels were detected by Western blot.This study protocol was approved by Ethic Committee of Xi'an No.1 Hospital (No.1504).Results Compared with HCFs,HKCs showed several distinguishing properties.First of all,its growth speed was faster,with collagen fibers decreased and attenuated.At the same time,mitochondrion swelled and mitochondrial cristae disappeared.Additionally,Golgi apparatus presented significant expansion and endoplasmic reticulum displayed severe swelling.There were statistically significant differences in A values between the two kinds of corneal fibroblasts at different time points after culture (Fgroup =5 023.13,P＜0.01;Ftime =38 518.16,P＜0.01),the A value of HKCs was significantly higher than that of HCFs at the same time point,and the difference was statistically significant (all at P＜0.01).The relative expression of α-SMA,COL3A1 and COL1 A1 was 120.00±5.77,158.33 ±4.41 and 88.33± 1.67,respectively in HKCs,the relative expression of α-SMA,COL3A1 and COL1 A1 was 100.00±0.00,100.00±0.00 and 100.00±0.00,respectively in HCFs,the relative expressions of α-SMA and COL3A1 were significantly increased in HKCs than those in HCFs,the relative expression of COL1 A1 was significantly decreased in HKCs than that in HCFs,with significant differences between them (t =-3.46,P ＜ 0.05;t =-13.23,P ＜ 0.01;t =7.00,P＜0.05).Conclusions HKCs are cultured and identied,which is suitable for establishing in vitro cell model of keratoconus.

PURPOSE: Coronary flow reserve (CFR) is recognized as an indicator of myocardial perfusion. The aim of this study was to assess the relationship between CFR in the non-infarcted myocardium and the incidence of major adverse cardiac events (MACEs). MATERIALS AND METHODS: 100 consecutive patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) were enrolled in the present study, and divided into MACE and non-MACE groups according to the incidence of 12-month MACEs. Left ventricular function and CFR were analyzed using two-dimensional echocardiography and myocardial contrast echocardiography at one week after PCI. Cardiac troponin I levels were assayed to estimate peak concentrations thereof. RESULTS: The MACE group was associated with lower CFR, compared to the non-MACE group (2.41 vs. 2.77, p < 0.001). In the multivariable model, CFR in the non-infarcted myocardium was an independent predictor of 12-month MACE (hazard ratio: 0.093, 95% confidence interval: 0.020–0.426, p=0.002) after adjustment for baseline demographic and clinical characteristics. CONCLUSION: CFR in the non-infarcted myocardium is a useful marker for predicting 12-month MACEs in patients with AMI undergoing primary PCI.

Objective To investigate the applicability of autoregressive integrated moving average (ARIMA) model in predicting healthcare-associated infection(HAI) in children.Methods The ARIMA model was constructed according to the incidence of HAI in a hospital from January 2011 to December 2014.With the use of information criterion,optimal model was determined;HAI data in 2015 was as test samples,the feasibility of the model was evaluated.Results ARIMA (0,1,1) was the optimal prediction model for HAI rate,the Akaike Information Criterion (AIC) and Bayesian Information Criterion(BIC) of the ARIMA (0,1,1) were 66.61 and 70.76,respectively.The Ljung-Box statistics value Q =14.14 was not significantly different (P =0.658),suggesting a white noise sequence of residuals with a good model fitting.The mean absolute percent error(MAPE) between actual and fitting value of HAI was 22.4,the actual values were within the 95％ confidence interval.Conclusion ARIMA model fits the time series data,and can achieve satisfactory effect on predicting the incidence of HAI in hospitalized children.

Objective To study the epidemiological and clinical features of human parainfluenza virus (HPIV) infection in children in Suzhou,and to provide the evidence-based foundation for early warning,diagnosis and treatment of respiratory infection in children.Methods The sputum specimens and medical history were obtained from children with acute respiratory tract infection hospitalized at the Childen's Hospital Affiliated to Soochow University from January 2006 to December 2015.Seven kinds of common respiratory viruses including respiratory syncytial virus,influenza virus A,influenza virus B,HPIV Ⅰ,HPIV Ⅱ,HPⅣV Ⅲ and adenovirus were detected by using the direct im-munofluorescence.Mycoplasma pneumoniae(MP),chlamydia pneumoniae,human bocavirns (hBoV) were detected by using fluorescence quantitative PCR.Rhinovirus and human metapneumovirus were detected by using reverse transcription-PCR.Sputum was cultured for bacteria.Results In 21 769 cases,the detection rate of HPIV positive was 3.21％ (829 cases),among which,HPIV Ⅰ,HPIV Ⅱ,HPIV Ⅲ were respectively detected in 113 cases (0.52％),16 cases (0.07 ％) and 700 cases (3.21％),respectively.There were 378 cases of simple infection and 428 cases of mixed infection,and the mixed infection was very common in Streptococcus pneumoniae,Haemophilus influenza,MP and hBoV.There was a difference in HPIV infection among genders,and the detection rate of the boys was higher than that of girls[4.14％ (563/13 591 cases) vs.3.25％ (266/8 178 cases),x2 =11.036,P =0.001].In the 28 d-1 year old and ＞ 1-3 year old group,the detection rate of HPIV was higher[4.71％ (494/10 476 cases) and 4.21％ (244/5 793 cases),respectively].In spring and summer,there was a higher detection rate of HPIV infection.The clinical manifestations with simple infection of HPIV Ⅰ and HPIV Ⅲ were cough,fever and wheezing.The rate of fever and shortness of breath in those of HPIV Ⅰ was 71.74％ (33/46 cases),10.87％ (5/46 cases),and that in HPIV Ⅲ was 40.12％ (134/334 cases),2.10％ (7/334 cases),HPIV Ⅰ infection was more likely to cause fever and shortness of breath than those of HPIV Ⅲ,there were significant differences (x2 =16.410,P ＜ 0.001;x2 =10.177,P =0.001).Pneumonia had the highest detection rate of viral infection.Conclusions HPIV Ⅲ is the leading pathogen among the types of HPIV in the hospitalized children in Suzhou area.Among the subtypes of HPIV,the peak of HPIV infection occurs in spring and summer.The children less than 3 years old are the most susceptible to parainfluenza virus,and the HPIV detection rate is gradually declines with age.

Objective To evaluate the diagnostic value of gastrin?17( G?17) and pepsinogen( PG) for gastric cancer. Methods A multicenter cross?sectional study of patients with continuous stomach discomfort from four centers including Changhai Hospital Affiliated to Second Military Medical University, the First Hospital Affiliated to Anhui Medical University, Qinghai Provincial People′s Hospital and the First Hospital Affiliated to Zhejiang University of Chinese Medicine from May 2014 to September 2015 was conducted. Before gastroscopy, fasting serum gatrin?17 and pepsinogen were analyzed by enzyme?linked immunosorbent assay(ELISA). The efficacy of G?17 and PG were evaluated according to endoscopic and pathological results. Results Based on the results of the pathological diagnosis, 1 122 cases were enrolled and divided into chronic atrophic gastritis group ( 548 cases ) , chronic non?atrophic gastritis group ( 370 cases), and gastric cancer group(204 cases). Serum G?17 and PGⅡ levels significantly increased(P<0?05) and PGR significantly decreased( P<0?05) in gastric cancer group compared with other groups. There was no significant difference in PGⅠlevel among three groups. The cut?off value of G?17 to diagnose gastric cancer was 7 pmol/L. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of G?17 for gastric cancer were 59?31%, 70?59%, 68?54%, 30?95% and 88?65% respectively. The cut?off value of PG Ⅰ/PG Ⅱ( PGR ) to diagnose gastric cancer was 7. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PGR for gastric cancer were 41?18%, 83?01%, 75?40%, 35?00% and 86?39% respectively. The cut?off value of PGⅡto diagnose gastric cancer was 10 μg/L. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PGⅡfor gastric cancer were 73?53%, 53?05%, 56?77%, 25?82% and 90?02% respectively. If G?17>7 pmol/L and PGR<7 was regarded as the cut?off value of diagnosis of gastric cancer, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 25?00%, 91?29%, 79?23%, 38?93%and 84?56%respectively. If G?17>7 pmol/L and PGⅡ>10μg/L was regarded as the cut?off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 48?04%, 79?74%, 73?98%, 34?51% and 87?35% respectively. If PGR<7 and PGⅡ>10 μg/L was regarded as the cut?off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 33?82%, 84?86%, 75?58%, 33?17% and 85?23% respectively. Based on logistic regression analysis of the independent variables of high serum G?17 value(>7 pmol/L), low serum PGR value(<7) and high serum PGⅡvalue(>10 μg/L), their OR value were 2?592, 2?237 and 1?864 respectively, and high serum G?17 value showed the highest risk of gastric cancer. Conclusion High serum G?17 and PGⅡ, low PGR are indicators of gastric cancer. Combination of G?17 and PGR has the best diagnostic value for gastric cacer. Gastric cancer can be screened in large scale by combining G?17 and PGR in order to improve the early diagnostic rate of gastric cancer and reduce the mortality of gastric cancer in our country.

Objective To observe the changes of serum ferritin and 25-(OH) vitamin D3 in patients with diabetic cranial neuropathy.Methods There were 50 patients without diabetic Cranial neuropathy,46 patients with diabetic cranial neuropathy,and 40 cases of normal control group.The changes of serum ferritin and 25-hydroxy vitamin D3 were observed in each group.The correlation between two indexes and the correlation with diabetic cranial neuropathy were analzyzed.Results The serum ferritin levels in diabetic group and diabetic neuropathy group were significantly higher than those in normal control group (P ＜ 0.01),and its level in patients with diabetic cranial neuropathy [(687.54 ± 65.38)ng/ml] was significantly higher than that of patients without diabetic cranial neuropathy [(497.28 ± 46.39) ng/ml,P ＜0.01].The serum 25-(OH) vitamin D3 levels in the diabetic group and diabetic neuropathy group were lower than those in the control group (P ＜ 0.01),and its level in patients with diabetic cranial neuropathy [(26.45 ± 8.93)nmol/l] was significantly less than that of patients without diabetic cranial neuropathy [(37.19-± 9.74)nmol/L,P ＜ 0.01].Serum ferritin levels were positively correlated with 25-(OH) vitamin D3 (r =-0.59,P ＜ 0.01).Multivariate unconditional Logistic regression analysis showed that diabetic neuropathy was negatively correlated with 25-(OH) vitamin D3 (P ＜ 0.05).Conclusions The increases of serum ferritin and 25-(OH) vitamin D3 are closely related to the occurrence and development of diabetic cranial neuropathy,which provides the theoretical basis for clinical intervention therapy.
