ABSTRACT
Objective:To realize the understanding level of cancer awareness of residents in Shanxi Province, and to provide a scientific basis for cancer prevention and treatment.Methods:In April 2020, 1 897 local residents in Shanxi Province were recruited to fill in the core knowledge questionnaire of cancer prevention and treatment. The basic demographic information and the core knowledge of cancer prevention and control were collected, and the influencing factors for the understanding of the core knowledge of cancer prevention and treatment were analyzed by using multivariate logistic regression model.Results:In the survey on the awareness rate of core knowledge of cancer prevention and control among residents in Shanxi Province, 37 940 items were answered, among which 29 396 items were known, and the awareness rate of the population was 77.48% (29 396/37 940). The single-factor results showed that there were statistically significant differences in awareness rates of core knowledge of cancer prevention and treatment among the population with different gender, household registration, ethnic groups, education degree, occupation and different frequency of the health examination were statistically significant (all P < 0.05); there were no statistically significant differences in awareness rates of core knowledge among the population with different age, and smokers or non-smokers (all P >0.05).Multivariate logistic regression analysis showed that education degree of junior middle school or above ( OR = 3.412-16.767, 95% CI 1.755-32.476) and receiving physical examination once a year ( OR = 2.291, 95% CI 1.154-4.549) were the favorable factors for knowing the core knowledge of cancer prevention and treatment. Household location in rural area ( OR = 0.522, 95% CI 0.378-0.722) and non-Han nationality ( OR = 0.369, 95% CI 0.151-0.904) were the unfavorable factors for knowing the core knowledge of cancer prevention and treatment. Conclusions:The awareness of core knowledge of cancer prevention and treatment among residents in Shanxi Province is good, so it is necessary to continue to strengthen the publicity of cancer prevention and control and improve the awareness of cancer prevention and control in the future.
ABSTRACT
Objective:To explore the clinical efficacy of Shugan Lidan decoction（SLD） combined with laparoscopic cholecystectomy on acute calculous cholecystitis（ACC），and explore its mechanism based on network pharmacology. Method:In a retrospective analysis， 121 patients with ACC were divided into laparoscopic cholecystectomy+SLD group （observation group， 68 cases） and laparoscopic cholecystectomy group（control group，53 cases）. The postoperative recovery of the patients （time to first exhaust，time to temperature recovery，antibiotic use time and hospitalization time），serum inflammatory factor levels ［white blood cell count（WBC），C-reactive protein（CRP），interleukin-6（IL-6）］，immune index levels［claster of differentiation（CD）3<sup>+</sup>，CD4<sup>+</sup>/CD8<sup>+</sup>，immunoglobulin M（IgM）］ and safety were compared between these two groups. The TCMSP，BATMAN-TCM and TCMIP databases were used to collect all chemical components and targets of SLD. GeneCard and OMIM databases were combined to search ACC-related targets，and then the intersection ones of SLD-related targets and ACC-related targets were extracted to obtain the potential action targets of SLD for treatment of ACC. The STRING database platform was used to establish and analyze the protein-protein interaction （PPI） network，and Bioconductor software package was used for Kyoto encyclopedia of genes and genomes（KEGG） pathway enrichment of the targets. Result:The time to first exhaust，antibiotic use time and hospitalization time of observation group were shorter than those of control group，and the differences were statistically significant（<italic>P</italic><0.05）. After treatment，the postoperative WBC，CRP，IL-6，CD4<sup>+</sup>/CD8<sup>+</sup> and IgM in the two groups of patients were lower than those before treatment，and the postoperative CD3<sup>+</sup> was higher than that before treatment，with statistically significant differences（<italic>P</italic><0.05）. The postoperative WBC，CRP，IL-6，CD4<sup>+</sup>/CD8<sup>+</sup> and IgM in the observation group were lower than those in control group，and the CD3<sup>+</sup> was higher than that of control group，with statistically significant differences（<italic>P</italic><0.05）. There was no statistical difference in adverse reactions between the two groups. Totally 159 components in SLD were screened，which acted synergistically on key targets such as IL-6，vascular endothelial growth factor A（VEGFA），insulin（INS），and epidermal growth factor receptor（EGFR），and participated in the regulation of HIF-1 signaling pathway，EGFR tyrosine kinase inhibitor resistance and PI3K-Akt signaling pathway in the treatment of ACC. Conclusion:SLD may regulate HIF-1 pathway and other signaling pathways by acting on IL-6，VEGFA，INS，EGFR and other targets，thereby reducing postoperative inflammatory factors，improving immune function，and promoting postoperative recovery in patients with ACC.

ABSTRACT
Objective To understand the incidence and mortality of malignancies as well as tumor burden of Shouyang County, Shanxi Province in 2012. Methods According to the review methods and the standards from the National Cancer Registry, the data of the incidence and mortality of malignant tumors in Shouyang County in 2012 were collected, collated and statistically analyzed. Results There were 389 new malignancies cases of Shouyang County in 2012, including 210 males and 179 females. The incidence rate was 187.61/100000 (190.00/100000 in males and 184.88/100000 in females). There were 263 death cases , including 164 males and 99 females. The mortality rate was 126.84/100000 (148.38/100000 in males and 102.25/100000 in females). The top 10 incidence of malignancies of the whole county was followed by lung cancer, cervical cancer, gastric cancer, liver cancer, colorectal anal cancer, esophageal cancer, breast cancer, bladder cancer, gallbladder cancer and uterus cancer, accounting for 86.12 ％ of the overall malignant cancers. The top 10 death malignancies of the whole county was followed by lung cancer, liver cancer, gastric cancer, esophageal cancer, Hodgkin disease, leukemia, colorectal cancer, bone cancer, brain tumor and pancreatic cancer, accounting for 87.45 ％ of the overall malignant cancers. Conclusion Lung cancer ranks first in the incidence and mortality of malignant tumors of Shouyang County, Shanxi Province, and the prevention and control of major tumors should be strengthened.
ABSTRACT
Aim To assess the effects of Trillium Tschonoskii Maxim ( TTM ) decoction on Tau protein phosphorylation and synaptic development in AD model rats induced by high activity GSK-3β. Methods The SD rats were divided into five groups of ten animals, named sham-operated group ( blank group) , AD model group, TTM group (0. 5, 0. 25, 0. 125 g·kg-1 · d-1 ) . Treatment group received gavage once a day for seven days with TTM decoction, while other groups by gavage once a day for seven days with drinking water. On 2nd day by gavage, Morris water maze test was used to assess the spatial learning and memory ability of the rats. After five days' training, rats in the treat-ment groups and AD model group were injected wort-mannin ( WT, PI3K specific inhibitor ) and GF-109203X (GFX, PKC specific inhibitor) (100 μmol ·L-1 of each, total volume of 10 μL) into the right lateral ventricle. Western blot was used to detect the levels of phosphorylation Tau protein at multiple sites and the expression level of PI3K, Akt, PKC, GSK-3β(S9, T216) and synapse-associated proteins. Immu-nohistochemical method was used to detect the hyper-phosphorylation of Tau protein in hippocampus of rats. Golgi staining was applied to detect the number and morphological changes of synaptic development and dendritic spines. Nissl' s staining was employed to ob-serve the development of neonatal neurons in hippo-campus and cortex. Results Western blot showed that the phosphorylation level of Tau in hippocampus increased in model group, and the activity of GSK-3βwas up-regulated. Among them, however, in middle dose TTM group, the phosphorylation level of Tau in hippocampus decreased and the activity of GSK-3βde-creased. The expression levels of p-PKC and p-Akt in low and middle dose treatment group were higher than those in model group, thus increasing the activity of PKC and Akt to inhibit the activity of GSK-3β kinase. Immunohistochemistry also indicated that TTM could decrease the biological effects of Tau phosphorylation in hippocampus of AD rats. Western blot showed that TTM could increase the expression levels of synapsin-1 , syn-aptophysin and GluR-1 in hippocampus of AD rats. Nissl staining showed that the number of Nissl bodies in hippocampal neurons of AD model group were signif-icantly fewer than those of sham operation group, which could be increased by TTM middle and high dose group, and the complexity and dendritic spine density of hippocampal neurons in AD rats could be en-hanced as well. Conclusion TTM can effectively im-prove the cognitive function of AD rats induced by the increase of GSK-3β activity, and its possible mecha-nism may be via down-regulating the activity of GSK-3β and inhibiting the phosphorylation of tau protein and promoting the development of neurons.
ABSTRACT
Purpose To study the clinical characteristics of disease development,pathology,treatment and prognosis in ovarian growing teratoma syndrome (GTS).Methods The clinical and pathological data of 1 cases of ovarian GTS were analyzed retrospectively,and the special course of disease and pathological changes were summarized.Results Ultrasound examination revealed a mass measuring 93 mm × 72 mm in the right ovary.Grossly,the tumor was cystic and solid,and solid area was mainly cauliflower like,with soft texture and small amount of hair and grease.Histopathological examination showed there were multifocal immature primitive neural tube in the solid area.Immunohistochemical staining showed the tumor cell were positive for NSE and focal positive for Syn,S-100,CD99,and CD56.In the preoperation,AFP and CA125 were 48.7 ng/mL and 84.2 U/mL.The right ovary mass and uterus,bilateral appendages,omentum and appendix were resected by radical operation,and two courses of chemotherapy postoperative were given.After 17 months,a solid peritoneal mass mesauring 47mm ×35mm × 24mm,was found in the original position by gynecological ultrasound.Grossly,it was solid and soft with some bone tissue.Histopathological examination showed a few immature cartilage and mesenchymal tissue.Tumor markers were within the normal range,the peritoneal mass and bilateral pelvic lymph nodes were excised thoroughly.A slight elevated in CA125 one month after surgery.After successive five courses of chemotherapy,no tumor recurred for 19 months follow up.Conclusion The diagnosis of GTS requires a combination of the overall course of the disease.The pathologic diagnosis of mature teratoma on postoperative recurred tumor are important indications for the differential diagnosis of GTS.Therefore,the tumor markers and abdominal and pelvic ultrasonography should be checked regularly,and reasonable treatment should be carried out aceording to the individual condition of the patient to avoid unnecessary chemotherapy.Keeping the fertility of young patients and preventing postoperative complications is the key to ensure a good prognosis.
