Objective To study the DSA hepatoarteriography manifestations in hepatic carcinoma after endocare cryocare system (ECS)treatment for improving the comprehensive therapy of hepatic carcinoma.Methods Thirty eight male patients with primary liver cancer ( n =32) and hepatic metastasis (n=6) were enrolled in this study. Common hepatic arteriography or super-selection angiography was performed in all patients after ECS treatment in 7 days and 30-60 days.Results The foci covered with ice ball were shown as round or ovoid. Single tumor less than 5 cm was covered completely, while the shape of focus covered with more ice ball showed irregularity, mass-like and diffuse nodulss with diseminated tumor vessels and tumor stains. The shortcoming of ECS included 18 missed areas, hepatic A-V shunt and hepatic A-portal V shunt in 4, bleeding in puncture tract 5, and extravasation of contrast material in 6 cases. Delineated margin existed between the frozon area and surrounding tissues.Conclusions ①ECS is effective on liver tumor 5 cm. ③ Tendency of missed areas in huge tumor and widespread nodes accurs after ECS. ④Complication occurs easily during ECS performance near the hepatic capsule and porta hepatis. ⑤TACE would improve comprehensive therapy effect of liver cancer about7 days after cryotherapy.

OBJECTIVETo investigate the efficacy of combined laparoscopic-endoscopic lower esophageal sphincterotomy and modified Dor fundoplication for cardiochalasia patients.

METHODSClinical data of 11 cardiochalasia patients who underwent combined laparoscopic-endoscopic lower esophageal sphincterotomy and modified Dor fundoplication by the same medical team from January 2015 to December 2016 at The Second Hospital of Jilin University were retrospectively analyzed. The procedure was as follows: an incision was made in the anterior wall of esophagus and dissection of esophageal muscular layer was performed, then the bulged esophageal mucosa was covered by the fundus after 180 degrees fold to the right (fundoplication), finally the gastric fundus was joined to the right diaphragmatic foot by 3 to 5 knotted suture. The efficacy was judged by the Eckardt scoring standard: the postoperative Eckardt score ≤3 points indicated effectiveness, otherwise the treatment was invalid.

RESULTSCombined laparoscopic-endoscopic lower esophageal sphincterotomy and modified Dor fundoplication was completed successfully in all the 11 patients without any subsequent laparotomy and death. The mean operative time was 85 (78 to 137) min, blood loss was 15 (5 to 35) ml, and no upper digestive tract perforation occurred. The mean postoperative hospital stay was 7.0(6 to 9) d. After the operation, the pressure of lower esophageal sphincter decreased significantly compared to that before operation [(5.31±6.23) mmHg vs. (35.72±17.13) mmHg, P<0.05], and the Eckardt score decreased significantly as well (0.53±0.56 vs. 6.17±1.17, P<0.05). During the follow-up of 2 to 23 months, there was no postoperative mortality. One case experienced mild gastroesophageal reflux 6 months after operation, and another patient had recurrent dysphagia 17 months after operation, who both were improved after receiving proton pump inhibitors or gastric dynamic drugs, and balloon dilation.

CONCLUSIONCombined laparoscopic-endoscopic lower esophageal sphincterotomy and modified Dor fundoplication is an effective and safe surgical procedure for cardiochalasia with minimal invasion and fast recovery.

Colorectal cancer (CRC) is the second most common cause of cancer-related death worldwide, and its high rates of relapse and metastasis are associated with a poor prognosis. Despite extensive research, the underlying regulatory mechanisms of CRC remain unclear. Long noncoding RNAs (lncRNAs) are a major type of noncoding RNAs that have received increasing attention in the past few years, and studies have shown that they play a role in many biological processes in CRC. Here, we summarize recent studies on lncRNAs associated with CRC and the signaling pathways and mechanisms underlying this association. We show that dysregulated lncRNAs may be new prognostic and diagnostic biomarkers or therapeutic targets for clinical application. This review contributes not only to our understanding of CRC, but also suggests novel signaling pathways associated with lncRNAs that can be targeted to block or eradicate CRC.

Intraoperative hemorrhage is the most common complication of laparoscopic radical gastrectomy,which is also the main cause of conversion to open surgery.With the popularization of laparoscopic surgery technology worldwide,how to complete high-quality surgery and effectively avoid intraoperative or postoperative complications is the goal pursued by all surgeons.Intraoperative hemorrhage in the laparoscopic radical gastrectomy is mainly divided into parenchymal hemorrhage,perigastric vascular injury-induced hemorrhage,lymph node hemorrhage and anastomotic bleeding.Compression,electrocoagulation,vascular clipping and vascular suture repair are the most common treatments for intraoperative hemorrhage.It is necessary to use above methods in clinical work.Proficiency in laparoscopic operation skills,familiarity with perigastric vascular anatomy and variation,and improved teamwork to reduce complications are the key to laparoscopic surgery for gastric cancer.Combined with literature reports,the authors summarize experience in laparoscopic surgery for gastric cancer,discuss the prevention and treatment of hemorrhagic complications during laparoscopic radical gastrectomy.

Objective:To investigate the predominant types of enteroviruses and the characteristics of the VP1 gene of coxsackievirus A4 (CVA4) causing hand, foot and mouth disease (HFMD) in Yunnan Province from 2018 to 2020.Methods:Throat swab and stool samples were collected from HFMD cases and tested by real-time quantitative PCR for nucleic acid detection. The samples positive for enterovirus nucleic acids were used for viral isolation and sent to the National Center for Disease Control and Prevention. The VP1 gene of the isolated strains was sequenced and analyzed.Results:From 2018 to 2020, a total of 21 757 HFMD samples were collected, 16 457 (75.64%) of which were positive for enteroviruses. Altogether 533 strains were isolated from 4 114 positive samples that were selected for viral isolation, including 89 strains of enterovirus 71 (EVA71, 16.70%), 180 strains of coxsackievirus A16 (CVA16, 33.77%), 76 strains of CVA10 (14.26%), 118 strains of CVA6 (22.14%), 26 strains of CVA4 (4.88%) and 44 strains of other types (8.26%). HFMD occurred mainly in children under five years old with higher incidence in males than in females (1.35∶1). The incidence of HFMD reached the peak in the second and third quarters. In Yunnan Province, CVA4 mainly circulated in Qujing and Kunming, and was sporadically detected in Wenshan and Honghe. The VP1 gene was 915 bp in length. Twenty-six CVA4 strains belonged to C2 subtype, which were genetically far from the prototype strain AY421762-HighPoint. Mutations in the VP1 gene were found at multiple sites including 18, 23, 34, 102, 148, 164, 200, 262, 174, 275, 285 and 303. These strains showed 80.4%-99.0% homology in nucleotide sequence and 95.6%-99.0% in amino acid sequence. Nucleotide mutations were mostly synonymous mutations.Conclusions:CVA16, CVA6, EVA71 and CVA10 were the predominant enteroviruses causing HFMD in Yunnan Province from 2018 to 2020. The prevalence of CVA4 was also worthy of attention. CVA4 isolates in Yunnan Province belonged to C2 subtype, mainly circulating in the east and southeast of Yunnan Province and gradually becoming a cocirculating predominant strain. Long-term dynamic monitoring would be of great public health significance for improving the sensitivity of HFMD early warning.

Adenocarcinoma of esophagogastric junction (AEG) has attracted more attention in recent years. Surgical method of Siewert type Ⅱ AEG is especially controversial, mainly focusing on the scope of lymph node dissection, safety of surgical margin, and digestive tract reconstruction. The abdominal transhiatal approach and right thoracoabdominal Ivor-Lewis approach are the main surgical approaches of totally laparoscopic or thoracoscopic surgery for Siewert type Ⅱ AEG, which not only need close teamwork, but also require rich experience in laparoscopic surgery. The authors has started to choose these two totally minimally invasive surgical approaches, the feasibility and safety of which are proved. The key surgical details are presented in this article for reference.

Objective To compare the value of ultrasound-guided fine-needle aspiration (FNA) and core needle biopsy (CNB) in diagnosing benign and malignant cervical lymph nodes.Methods A retrospective analysis was performed on 88 patients who received biopsy for cervical lymph node enlargement from January 2015 to May 2017.FNA (n =39) or CNB (n =49) were performed respectively to compare the sensitivity,specificity and accuracy of the two methods in diagnosing benign and malignant cervical lymph node enlargement.Results 84.6％ (33/39) of FNA cases were successfully collected,and 98％ (48/49) of FNA cases were successfully collected for definite pathological diagnosis (P =0.000).The sensitivity,specificity and accuracy of FNA and CNB in diagnosing malignant cervical lymph nodes were 90.9％ and 97.2％,94.1％ and 100％,92.3％ and 98％,respectively.Compared with FNA,there were statistically significant differences in sensitivity,specificity and accuracy in differentiating benign and malignant lymphatic lesions in cervical enlargement (P ＜0.01).The sensitivity and specificity of FNA and CNB in diagnosing cervical lymph node metastatic carcinoma were 100％ and 100％,95.2％ and 100％.Compared with FNA,there was no statistically significant difference in the sensitivity to the diagnosis of cervical lymph node metastatic carcinoma (P =0.102).Conclusions CNB is superior to FNA in sensitivity,specificity and accuracy in diagnosing cervical lymphadenopathy.However,when metastatic cancer was diagnosed,FNA was not significantly different from CNB in sensitivity (P =0.102),and FNA was recommended as the first choice.

Intra-abdominal infection complicated with hypothyroidism is very common. It mostly featured decreased T3, with or without decreased T4, and without elevated thyroid stimulating hormone(TSH). This particular type of hypothyroidism was called "low T3 syndrome" or "thyroid illness syndrome", and is called "non-thyroid illness syndrome" increasingly in recent years. Its pathogenesis has not been fully understood, and probably is associated with abnormality of hypothalamic-pituitary-thyroid axis, disorder of peripheral thyroid hormone metabolism, change in thyroid hormone binding protein, regulation of triiodothyronine receptors, effect of cytokines, and lack of trace element selenium. Intra-abdominal infection complicated with hypothyroidism should be differentiated from primary hypothyroidism, which may be one cause of mental depression, insufficient anabolism, and poor tissue healing. Therefore, the changes of T3 and T4 levels should be actively monitored in patients with severe or prolonged intra-abdominal infection. Whether treatment is needed for intra-abdominal infection complicated with hypothyroidism remains controversial. T3 replacement therapy may improve prognosis. When low T3 syndrome presents as a disease-mediated hypothyroidism, we recommend the use of levothyroxine(L-T4) or liothyronine (L-T3) treatment to improve the prognosis of critical patients. Enteral nutrition can improve hypothyroidism and has good efficacy for enterocutaneous fistula patients with intra-abdominal infection.

Objective: To evaluate the relationship between platelet distribution width(PDW) and the extent of coronary artery disease and 2-year outcome in patients received percutaneous coronary artery intervention(PCI) because of stable coronary artery disease(SCAD). Methods: We consecutively enrolled 4 293 patients who received PCI because of SCAD in Fuwai Hospital from Jan 2013 to Dec 2013, patients were followed up for 2 years. Patients were divided into three groups according to tertiles values of PDW as follows: PDW≤11.4%(1 402 patients), 11.4%12.9% (1 450 patients). Major adverse cardiovascular and cerebrovascular events (MACCE) were defined as the occurrence of death, myocardial infarction, target vessel revascularization, intra stent thrombosis and stroke during follow-up. Multivariable logistic regression was used to evaluate the relationship between PDW and the extent of CAD. Multivariable Cox regression was used to evaluate the relationship between PDW and prognosis of SCAD patients. Results: PDW was associated with diabetes mellitus, body mass index, red cell distribution width, mean platelet volume (MPV), platelet counts and glycosylated haemoglobin (P<0.05), but not associated with age, sex, estimated glomerular filtration rate (P>0.05). PDW was not correlated with the extent of CAD(P=0.990), SYNTAX score(P=0.721), no-reflow phenomenon after PCI(P=0.978). Multivariable logistic regression also showed no relationship between PDW and extent of CAD (OR=0.994, 95%CI 0.961-1.029, P=0.73). PDW was found to be an independent risk factor of 2-year cardiac death (HR=1.242, 95%CI 1.031-1.497, P=0.022), but was not an independent risk factor of all-cause death and MACCE. Conclusions PDW is not related with the extent of coronary artery disease. PDW is an independent risk factor of 2-year cardiac death, but is not an independent risk factor of all-cause death and MACCE in this patient cohort.
