Objective To investigate the clinical efficacy of combination treatment of Ambroxol,Ipratropium and Budesonide during perioperative period in elderly patients with cardiac adenocarcinoma and chronic obstructive pulmonary disease(COPD).Methods A total of 126 elderly patients aged over 65 years diagnosed as cardiac adenocarcinoma and COPD were selected,and no chemotherapy was given to them before operation.Patients were randomly divided into experimental group(n= 62)and control group(n= 64).Intravenous infusion of Ambroxol hydrochloride and atomizing inhalation of Ipratropium were given in both groups,and the experimental group received budesonide additionally.The pulmonary function,postoperative pulmonary atelectasis,pulmonary infection,antibiotics application and hospitalization after operation were compared between the two groups.Results The forced expiratory volume at the first second(FEV1),forced vital capacity(FVC)and FEV1/FVC were higher in experimental group than in control group [(1.79 ± 0.52)1 vs.(1.33 ± 0.38)L,(2.44 ±0.43)Lvs.(1.93 ± 0.36)L and(73.91 ± 8.17)% vs.(62.87 ± 7.23)%,respectively,allP<0.05].The postoperative pulmonary atelectasis and pulmonary infection were lower in experimental group than in control group(4.8% vs.15.6%,6.5% vs.18.8%,respectively,both P<0.05).The time for antibiotics application after operation had no difference between the two groups[(4.81±1.20) days vs.(5.98 ± 1.17)days,P > 0.05].There was a significant difference in postoperative hospitalization between the two groups [(8.37 ± 0.27) days vs.(11.80 ± 0.33) days,P < 0.05].Conclusions The combination treatment of Ambroxol hydrochloride,Ipratropium and Budesonide during perioperative period achieves better therapeutic effects than does the combination treatment of ambroxol hydrochloride and ipratropium in elderly patients with cardiac adenocarcinoma and COPD.

OBJECTIVE:
To assess the association of genomic instability of epithelial cadherin 1 (CDH1) gene and clinicopathological characteristics of gastric cancer.
METHODS:
In total 120 paraffin-embedded gastric cancer tissue specimen were prepared, and genomic DNA was extracted. The genomic instability of the CDH1 gene was analyzed by immunohistochemistry and silver staining PCR-single-strand conformation polymorphism.
RESULTS:
The number of information individuals (heterozygotes) was 98 for the D16S752 locus. The detection rates for microsatellite instability (MSI) and loss of heterozygosity (LOH) at the D16S752 locus and the positive rate of CDH1 protein were 19.39%, 16.33% and 51.02%, respectively. The detection rate of MSI in TNM stages I or II was significantly higher than that in stages III or IV (P<0.05) while the detection rate of LOH was significantly lower than that in stages III or IV (P<0.05). The positive rate of CDH1 protein in TNM stages III or IV was significantly lower than that in stages I or II (P<0.05). The detection rate of MSI of cases with lymph node metastasis was significantly lower than that of without lymph node metastasis (P<0.05) while the detection rate of LOH was significantly higher than that without lymph node metastasis (P<0.05). The positive rate of CDH1 protein in patients with lymph node metastasis was significantly lower than that in patients without lymph node metastasis (P<0.05). The positive rate of CDH1 protein in MSI-positive group was significantly higher than that in MSI-negative group (P<0.05), and the positive rate of CDH1 protein in the LOH-positive group was significantly lower than that the LOH-negative group (P<0.05).
CONCLUSION
The genomic instability of the CDH1 gene is associated with the progression of gastric cancer. MSI at the D16S752 locus may be used as a molecular marker for early gastric cancer, while LOH at this locus mostly occurs in advanced gastric cancer and can be regarded as an effective indicators for malignancy evaluation and prognosis.

Objective To investigate the effects of miR-325-3p on the EMT, invasion and metastasis of gastric cancer cells by targeting CLDN1 gene. Methods We selected human gastric epithelial cell lines GES-1 and gastric cancer cell lines HGC27, SGC-7901, MKN-45 and MGC-803, and detected the expression of miR-325-3p and CLDN1. The targeting relation between miR-325-3p and CLDN1 were verified by dual luciferase report experiments, and the expression of miR-325-3p and CLDN1 in gastric cancer cells were intervened. qRT-PCR and Western blot were adopted to detect N-cadherin, vimentin and MMP2 expression in cells. CCK-8 assay, Transwell assay, flow cytometry were utilized to detect cell proliferation activity, invasion and apoptosis, respectively. Results Compared with GES-1 cells, miR-325-3p expression was decreased while CLDN1 expression was increased in MGC-803 cells (

OBJECTIVETo observe the change of myeloid-derived suppressor cells (MDSCs) percentage in peripheral blood after operation in rectal cancer patients and to examine its association with the prognosis.
METHODSBlood samples of pre-operation and postoperative 21-day from 64 stage I(-III( rectal cancer patients who underwent surgery in Department of General Surgery, The Affiliated Cancer Hospital, Zhengzhou University between January and December 2009 were collected. MDSCs percentage was detected by flow cytometry. Its association with the prognosis of patients was analyzed.
RESULTSMDSCs percentage of postoperative 21-day decreased significantly compared with pre-operation (P<0.01). When local recurrence or distant metastasis presented, MDSCs percentage increased again (all P<0.01) and reached the preoperative level(P>0.05). All the patients were further divided into two groups based on median MDSCs percentage. Patients with higher MDSCs percentage before operation (>3.78%) and after operation (>2.11%) had significantly lower 5-year overall survival(OS) (58.1% and 62.1%) and 5-year disease-free survival (DFS)(54.8% and 58.6%) as compared to those with lower MDSCs percentage(5-year OS 87.9% and 84.8%; 5-year DFS 82.8% and 80.0%, all P<0.05). Multivariate analysis showed that preoperative MDSCs percentage was an independent prognostic factor of rectal cancer(HR:4.065, 95% CI:1.026 to 16.108, P=0.04).
CONCLUSIONSPreoperative increased MDSCs percentage may be an important predictor of poor OS in rectal cancer patients. Dynamic change of MDSCs percentage can reflect the disease development.

Objective:To investigate the feasibility and advantages of unilateral primary hyperparathyroidism (PHPT) treated by transthyretal interosseous muscle approach surgery.Methods:Clinical data of 7 patients with unilateral PHPT treated by interstitial sternocleidomastoid muscle approach from Jan. 2021 to Feb. 2022 in the thyroid surgery of China-Japan Union Hospital of Jilin University were retrospectively analyzed, including preoperative blood calcium concentration, operation time, incision length, intraoperative parathyroid hormone (PTH) , blood calcium concentration and PTH value in the first month after surgery, abnormal sensation of the skin in the anterior cervical area, etc. The feasibility and advantages of interstitial sternocleidomastoid muscle approach surgery for unilateral PHPT were analyzed.Results:All 7 patients with unilateral PHPT were operated successfully. The PTH was 17.2-63.3 pg/ml on recheck 1 month after surgery, which were all within the normal range. The time from skin opening to resection of the diseased parathyroid gland was 20-35 min, and the length of the surgical incision was 3-4 cm. all patients were given intravenous and oral calcium therapy after surgery, and the blood calcium and PTH levels were within the normal range at 3-12 months of follow-up; the incision recovered well, and there was no significant sensory and functional abnormalities in the anterior neck area.Conclusion:The treatment of unilateral PHPT through the sternocleidomastoid interosseous approach can ensure the safety and efficacy of the operation while better protecting the sensory and motor functions of the anterior cervical region and improving the aesthetics of the surgical incision.
