Analysis on the Incidence and Economic Burden of Patients with Lung Cancer / 中国肺癌杂志

BACKGROUND@#The previous study has indicated that lung cancer has a high incidence and mortality in China, and has caused a large economic burden. The purpose of this study was to analyze the incidence and economic burden of lung cancer by analyzing the information on the home page of discharge history of lung cancer patients in Hebei Tumor Hospital, and to provide scientific basis for the prevention and treatment of lung cancer.@*METHODS@#The information of all of the discharges, new cases, surgical patients, age, gender, length of stay and hospitalization cost of lung cancer patients in Hebei Tumor Hospital from January 2012 to December 2019 were retrieved based on the medical record management system, and the incidence trend, gender and age distribution as well as the economic burden of the disease were statistically described.@*RESULTS@#The number of new cases of lung cancer increased year by year, from 2,235 cases in 2012 to 5,012 cases in 2019. The number of males always outnumbered females, but the gender ratio decreased year by year, from 2.25 in 2012 to 1.56 in 2019. Among new cases of lung cancer, the proportion of surgical treatment increased year by year, from 28.14% in 2012 to 44.83% in 2019. Except for 2012, the proportion of surgical operations in female patients was higher than that in male patients from 2013 to 2019. The proportion of surgical operations in male and female patients was 23.52% and 28.07% in 2013, and 36.14% and 58.37% in 2019, respectively. The median age at the onset of lung cancer has increased year by year, from 61 years old in 2012 to 63 years old in 2019. The median age of onset in all lung cancer patients was higher in males than in females. The number of new lung cancer patients and surgical patients both showed an increasing trend with the increase of age, and both reached the maximum value in the age group of 60-69 years old. With the increase of age, the number of patients gradually decreased. The median length of hospital stay for all discharged lung cancer patients or surgical patients decreased year by year, from 10 d and 19 d in 2012 to 8 d and 17 d in 2019, respectively, while the median hospitalization cost increased year by year. It increased from 10,611.46 yuan and 38,750.13 yuan in 2012 to 17,187.15 yuan and 84,030.16 yuan in 2019, respectively.@*CONCLUSIONS@#Lung cancer is still one of the main cancers endangering the health of Chinese residents. The incidence of lung cancer is increasing year by year, and the distribution of gender and age has certain characteristics. In order to reduce the number of cases and the economic burden, effective prevention and control measures should be formulated and medical reform should be strengthened.

Epidemiological situation of human parasitic diseases through three investi-gations in Jinhu County,Jiangsu Province / 中国血吸虫病防治杂志

Objective To understand the epidemiological situation of human parasitic diseases in Jinhu County,so as to pro?vide the evidence for formulating further control strategy. Methods The investigated local residents were sampled by the ran?dom cluster sampling method in 1989,1999 and 2015. The infections of intestinal helminthes were detected by Kato?Katz tech?nique,the eggs of Enterubius vermicularis were examined by cellophane anal swab for children,the intestinal protozoa were ex?amined by the saline smear and iodine staining methods. Results The total rates of parasitic infections were 62.57%,9.32%and 0.49%in 1989,1999 and 2015,respectively. Compared to those in 1989 and in 1999,the infection rate in 2015 was de?creased by 99.22%and 94.74%,respectively. The numbers of detected parasite species were 14,10 and 4 in 1989,1999 and 2015,respectively. The intensities of infections were mainly mild in three investigations,and the intensities of all the infections in 2015 were mild. The species of infected parasites were mainly single,however,multiple infections were observed in 1989,in?cluding 4 parasite species(0.72%)and 3 parasite species(7.02%). Only in 1989,the difference between sexes was significant and the infection rate of the female was higher than that of the male(χ2=18.01,P<0.01). Conclusions The infection rates of human parasites are decreased gradually and stabilized at the low level in Jinhu County. However,the surveillance work still should be strengthened to consolidate the achievement.

<p><b>OBJECTIVE</b>To investigate the possible role and significance of soluble programmed death-1 (sPD-1)/soluble programmed death ligand 1 (sPD-L1) in the pathogenesis of oral lichen planus (OLP).</p><p><b>METHODS</b>Thirty-six patients with OLP (20 cases of reticular OLP and 16 cases of erosive OLP) were enrolled in this study, and 18 healthy people served as controls. Lymphocyte subsets (CD3⁺, CD4⁺, CD8⁺, CD19⁺, CD16⁺ + 56⁺) were examined by flow cytometric analysis and humoral immunity indexes (IgG, IgA, IgM, C3, C4) tested by nephelometry immunoassay. The levels of sPD-1 and sPD-L1 proteins in serum of patients with OLP were determined by enzyme-linked immunosorbent assay. The correlations between the level of sPD-1, sPD-L1 proteins and the immune status and clinical characteristics of patients with OLP were analyzed by SPSS 19.0.</p><p><b>RESULTS</b>CD3⁺, CD4⁺, CD8⁺, CD16⁺ + 56⁺ in patients with OLP were decreased compared with the normal value, while CD19⁺ in patients with OLP was increased compared with the normal value (P < 0.05). C3 and C4 in patients with OLP were decreased compared with the normal value, but IgM in patients with OLP was increased (P < 0.05). The levels of sPD-1 and sPD-L1 proteins in patients with OLP were significantly higher than that in control group [26.10(8.81, 40.00) ng/L vs 17.65(0.00, 26.10) ng/L, 29.53(21.47, 36.76) ng/L vs 22.79(1.19, 28.29) ng/L] (P < 0.05), but the expression of sPD-1 and sPD-L1 was not related with clinical characteristics of OLP. There were negative correlations between the levels of sPD-1 protein and CD4⁺ T cells or CD16⁺ + 56⁺ cells (r1 = -0.378, P1 = 0.007; r2 = -0.365, P2 = 0.009), while there was a positive correlation between the levels of sPD-1 and CD19⁺ B cells (r = 0.482, P = 0.000). There was a negative correlation between sPD-L1 expression level and CD4⁺ and a positive correlation between sPD-L1 expression level and IgG (r¹ = -0.286, P1 = 0.044; r² = 0.365, P₂= 0.029).</p><p><b>CONCLUSIONS</b>In patients with OLP, the cellular immune function is low with humoral immunity function disorder.

Expression and methylation status of CAV-1 gene in esophageal squamous cell carcinoma / 中国癌症杂志

Background and purpose: As one of the important epigenetic phenomena, DNA methylation plays an important regulatory function for the expression of genes. Study shows that abnormal changes of DNA methy-lation patterns of normal tumor cell genome leads to dysfunction of cancer related gene, and this may be associated with tumor occurrence and development. The study investigated the promoter methylation and expression of caveolin-1 (CAV-1) gene in esophageal squamous cell carcinoma (ESCC), and to elucidate its role in ESCC. Methods:We used MSP approach, RT-PCR, and immunohistochemistry method respectively to examine the methylation status of the 5’CpG island of CAV-1 gene and its expression at mRNA and protein levels in tumors and corresponding normal tissues. Results: CAV-1 mRNA expression in tumor tissues (0.86±0.56) was signiifcantly higher than that in corresponding normal tissues (0.40±0.36, P0.05). The promoter methylation frequency of CAV-1 in tumor specimens was 2.0%(1/51), and the methylation phenomenon has not been found in corresponding normal tissues. The promoter methylation fre-quency of CAV-1 in tumor specimens showed no signiifcant difference compared with the corresponding normal tissues (P>0.05). Conclusion:The mRNA and protein expression of CAV-1 in tumor specimens was signiifcantly higher than that in corresponding normal tissues. Aberrant high expression of CAV-1 has played a certain role in promoting tumori-genesis and lymph node metastasis. The expression both in ESCC and corresponding normal tissues has no correlation with the promoter methylation status.

Icarrin increases bone morphogenetic protein 2 and Osterix expression in rat osteoblast / 中华内分泌代谢杂志

Objective To observe the effect of icarrin on proliferation and differentiation of rat osteoblasts cultured in vitro as well as the expressions of bone morphogenetic protein-2 (BMP-2) and Osterix in rat osteoblast.Methods Calvarial osteoblasts were obtained from newborn (＜ 24 h) SD rats by trypsin-collagenase digestion.The culture medium with different icarrin concentrations and the second generation osteoblasts were mixed.The mRNA expressions of BMP-2,Osterix,ALP,and Col Ⅰ were detected by semiquantative RT-PCR.Then the second generation osteoblasts were cultured in the medium containing icariin (10 ng/ml) with or without BMP-2 antibody.After48 h,RT-PCR was used to estimate the mRNA expression of Osterix.Results In comparison with the control group,the mRNA expressions of BMP-2,Osterix,ALP,Col Ⅰ were increased in a dose-dependent manner (P＜0.05) with a maximal effect at the concentration of 10 ng/ml.The mRNA expression of Osterix treated with the mixture of icarrin and BMP-2 antibody was significant decreased(P＜0.05),and compared with the group of icarrin,however,the difference between the BMP-2 group and the mixture group was not statistically significant (P ＞ 0.05).Conclusions Icarrin stimulates proliferation and differentiation of cultured osteoblast in vitro by increasing the mRNA expression of ALP and Col Ⅰ.Icarrin could stimulate Osterix gene expression by enchancing BMP-2 gene expression,finally,it could induce bone formation and prevent and/or treat osteoporosis.

Clinical efficacy and safety of atorvastatin on atherosclerosis in advanced elderly patients / 中华老年医学杂志

Objective To investigate the effect and safety of long-term use of atorvastatin on carotid atherosclerosis in advanced elderly patients.Methods Totally 61 elderly patients with carotid atherosclerosis were permitted into study.They were treated with atorvastatin (20 mg/d) and followed-up for five years.The carotid atherosclerosis parameter and the serum levels of TC,TG,LDL-C,HDL-C,fasting blood glucose (FBG),ALT,AST,STB,CB,Bun,Cr and creatine kinase (CK) were measured before and 5 years after treatment.Results During fellow-up,2 patients died of severe pneumonia and 1 patient died of operation complications of intestinal obstruction,with mortality rate of 4.9％.2 patients (3.4％) gave up treatment because of muscle-related side-effect.Data was collected in 56 patients achieving study end.There was significant decrease in LDL-C (P＜0.05) and increase in HDL-C (P＜0.05),but there was no change in serum levels of TC,TG,FBG,ALT,AST,STB,CB,BUN,Cr and CK (P＜0.05) after 5 years.The total area of carotid atherosclerosis plaque was reduced [(0.63±0.41)cm2 vs.(1.07±0.67)cm2,P＜0.05] and echo of carotid atherosclerosis plaque was enhanced (2.67±0.52 vs.1.53±0.44,P＜0.01),but carotid intima-media thickness(IMT) appeared no change after five years.Conclusions Atorvastatin is safe in the treatment of advanced elderly patients,it can make carotid atherosclerosis plaque smaller and stable after long-term treatment.

The protective effects of bifidobacterial adhesin on ischemic reperfusion injury of intestine in rats / 中华内科杂志

ObjectiveTo investigate the protection effect of bifidobacterial adhesin for intestine ischemia/reperfusion (I/R) injury on gut barrier function in rat.MethodsSeventy-two male SD rats were randomly divided into sham operation group (n =24), I/R model group (n =24) and pretreatment group of bifidobacterial adhesin (pretreatment group, n = 24).Six rats were anatomized at 6 h, 1 d, 4 d and 7d after inducing I/R model in each group, respectively.The pathological changes of the terminal ilea and the blood levels of TNFα, IL-6, IL-10, diamine oxidase (DAO), and the activity and content of D-lactic acid were observed.ResultsThe blood levels of TNFα, IL-6, DAO and D-lactic acid in I/R model group were significantly higher than sham operation group at all time points (P ＜0.05) , while the blood level of IL-10 was no significantly change.The activity of IL-6 and DAO in pretreatment group was significantly lower than I/R model group at all time points (P ＜ 0.05), the blood level of TNFαt in pretreatment group was significantly lower than I/R model group at 1 d, the blood level of D-lactic was significantly lower than I/R model group at 4 d and 7 d (P ＜ 0.05). Intestinal pathological damages were obviously milder in pretreatment group than I/R model group at all time points (Chiu's pathological scores: 6 h, 3.22 ±0.22 vs 3.57 ±0.20;1 d,3.77 ±0.13 vs 3.90 ±0.12;4 d,2.93 ±0.23 vs 3.07 ±0.21;7 d,2.10 ±0.30 vs 2.22 ±0.17,all P ＜ 0.05).ConclusionThe pretreatment of bifidobacterial adhesin could protect the intestinal mucosa from I/R injury, and alleviate intestinal ischemic reperfusion injury.
