To investigate the application value of disposable subscope-assisted intestinal metal stent placement in the treatment for acute malignant colorectal obstruction, a retrospective analysis was conducted on the patients who underwent intestinal metal stent placement assisted by disposable subscope for acute malignant colorectal obstruction at the Digestive Endoscopy Center, Affiliated Hospital of Yangzhou University from June 2023 to July 2024. The technical success rate, clinical success rate, operation time, postoperative complications and first-stage surgical resection anastomosis rate of intestinal metal stent placement assisted by subscope were analyzed. Among the 16 included patients, there were 10 males and 6 females, with the age of 72.19±9.40 years. Obstruction occurred at the descending colon in 8 cases (50.00%), at the sigmoid colon in 6 cases (37.50%), at the rectosigmoid junction in 1 case (6.25%), and at the splenic flexure of the transverse colon in 1 case (6.25%). All 16 patients successfully underwent stent placement, with a technical success rate of 100.00% (16/16). Obstruction symptoms did not relieve in one patient (6.25%) after stent placement, resulting in a clinical success rate of 93.75% (15/16). The endoscopic operation time for the 16 patients was 37.8±13.9 minutes. No bleeding, perforation, stent displacement, or detachment occurred after the operation. Fourteen patients underwent subsequent surgical treatment, the first-stage surgical resection anastomosis rate was 71.43% (10/14). This preliminary study suggests that the disposable subscope-assisted intestinal metal stent placement for the treatment of acute malignant colorectal obstruction is safe and effective, with no radiation exposure.

Objective To evaluate the feasibility and safety of thoracoscopic lung cancer surgery under non-tracheal intubation anesthesia. Methods Twenty patients with peripheral lung cancer were enrolled in experimental group and control group. Then monitored and recorded Systolic pressure (SBP), diastolic pressure (DBP), mean arterial pressure (MAP), heart rate (HR), electrocardiogram (ECG), heart rate (HR), Oxygen saturation (SpO2), Final moisture CO2 partial pressure (PETCO2), central venous pressure, invasive arterial blood pressure and blood glucose and the related complications like sore throat, hoarse voice, nausea and so onin such time points: before induction (T0), induction of intubation (T1), operation (T2), and sudden removal (T3) of the two groups. Results The laryngeal mask group was given a smaller stimulus to the cardiovascular system during anesthesia.The time of feeding, the exhaust, the time of getting out of bed, the average hospitalization day, the reduction of hospitalization expenses, pharynx, respiratory and cardiovascular complications were shorter and less than intubation group. Conclusion The laryngeal mask ventilation intravenous anesthesia with thoracic vagal nerve block in the thoracoscopic lobectomy is simple, safe, no intubation-related complications and single lung ventilation lung injury, in line with surgery -anesthesia overall minimally invasive development concept, worthy of clinical promotion.

Objective To explore whether polymorphisms in non-coding RNA has potential as biomarkers for predicting the risk of kidney transplantation rejection.Methods A total of 79 patients who had received kidney transplants were recruited from the First Affiliated Hospital of China Medical University and divided into the rejection group (n =26) and non-rejection group (n =53).Four polymorphisms in miRNA and 8 polymorphisms in lncRNA were detected by MALDI-TOF-MS.Results When compared with the wild genotype,the mutation genotype in miR-27a rs895819 and lnc-LRFN2-2 rs61516247 had 11.72 and 4.87 folds increased risk of kidney transplantation rejection (P =0.046,OR=1.04-131.74 and P =0.047,95％ CI =1.02-23.21,respectively).The other three polymorphisms in miRNA and 7 polymorphisms in lncRNA showed no significant associations with transplantation rejection risk (P ＞ 0.05).Conclusion The miR-27a rs895819 and lnc-LRFN2-2 rs61516247 polymorphisms were associated with the risk of kidney transplantation rejection.

To study the chemical constituents of K. oblongifolia, silica gel column chromatography, MCI and Sephadex LH-20 were used to separate the 70% acetone extract of the stems of K. oblongifolia. The structures of the isolated compounds have been established on the basis of physicochemical and NMR spectroscopic evidence as well as ESI-MS in some cases. Twenty compounds were obtained and identified as heteroclitalignan A (1), kadsulignan F (2), kadoblongifolin C (3), schizanrin F (4), heteroclitalignan C (5), kadsurarin (6), kadsulignan O (7), eburicol (8), meso-dihydroguaiaretic acid (9), kadsufolin A (10), tiegusanin M (11), heteroclitin B (12), (7'S)-parabenzlactone (13), angeloylbinankadsurin B (14), propinquain H (15), quercetin (16), kadsulignan P (17), schizanrin G (18), micrandilactone C (19) and (-)-shikimic acid (20). Compouds 1, 5, 8, 11-15, 18 and 20 were isolated from this plant for the first time. Toxicity of compounds 1-10 were evaluated with zebrafish model to observe the effect on its embryonic development and heart function. The results showed that compounds 7, 9 and 10 caused edema of zebrafish embryo and decreased the heart rate of zebrafish, which exhibited interference effect on heart development of zebrafish.

Objective To investigate the relationship of Twist induced epithelial mesenchymal transitions (EMT) during pancreatic carcinoma progression.Methods The expressions of Twist,N-cadherin and Vimentin proteins were tested by immunohistochemistry in 42 cases of pancreatic carcinomas and 26 cases of adjacent paracancerous tissues.Results The positive rates of Twist,N-cadherin and Vimentin in 42 cases of pancreatic carcinomas were 76.2％,59.5％ and 57.1％,respectively.The positive rate of Twist,N-cadherin and Vimentin were all significant between pancreatic carcinomas and paired tumor-adjacent paracancerous tissues (all P ＜0.001).The differences of the expression of Twist,N-cadherin and Vimentin in pancreatic carcinoma of tumor differentiation,TNM stage,neural invasion and lymph node metastasis were significant (all P ＜ 0.05).Significantly positive correlation was found between the expression of Twist and the others (N-cadherin and Vimentin) by using spearman correlation analysis (r =0.506,P =0.001 ; r =0.417,P =0.006).Significantly positive correlation was found between the expression of N-cadherin and Vimentin by using spearman correlation analysis(r =0.462,P =0.002).Conclusions Twist signaling pathway activation might mediate pancreatic epithelial cells to EMT and then promote pancreatic carcinoma invasion and metastasis.

OBJECTIVETo provide practical method for microscopic authentication of traditional Chinese medicine Gusuibu and its adulterants.

METHODBy means of light microscope, scanning electron microscopy and tissue section techniques, the morphology, the size of the rhizome scales and their bearing position in the original plants of Gusuibu and its adulterants, i. e. Drynaria roosii, D. delavayi, D. quercifolia and Pseudodrynaria coronans were analyzed.

RESULTThere were significant differences between scales length of D. roosii, D. delavayi and P. coronans, while there was no significant difference between that of D. roosii and D. quercifolia. The scale teeth of D. delavayi were usually curved, bifid and uneven distributed at the scale fringe, which was different from that of the other three species. The base of the scales sinks in epidermis in D. roosii, D. quercifolia, and P. coronans, while it bore at the raised part of epidermis in D. delavayi.

CONCLUSION[corrected] Morphology, size and bearing position of the rhizome scales have significant differences in the several species. Therefore, these characteristics can be applied to the identification of Gusuibu and its adulterants.
