Gastric cancer is one of the most common gastrointestinal malignant tumor in our country,with the continuous development of minimally invasive surgical technology,laparoscopic radical gastrectomy has gradually been developed,but whether CO2 pneumoperitoneum can cause peritoneal metastasis remains controversial.This article has synthesized the recent reports to illustrate the influence of Heat-CO2 pneumoperitoneum on adhesion molecules,and introduce the latest viewpoint of adhesion molecules affect gastric cancer metastasis.This article can provide clues to evaluate the clinical application value of Heat-CO2 pneumoperitoneum.

Objective To research the correlation of single nucleotide polymorphisms(SNPs) of Plasmacytomas Variant Translocation Gene(PVT1) and diabetes nephropathy.Methods To assay PVT1 SNPs (rs10808565,rs13447075,rs2648862,rs2720709,rs2648875) in two groups individuals with diabetes nephropathy and diabetes by MassARRAY system.Then analysis the results by statistical methods to evaluate the relationship between PVT1 SNPs and diabetes nephropathy.Results The distributions of SNPs of PVT1 (rs10808565,rs13447075,rs2648862,rs2720709,rs2648875) were all under the Hard-Weinberg equilibrium in two groups.Difference in PVT1 rs2648875 between two groups was statistically significant(P<0.05);and there were no significant differences in the others SNPs (rs10808565,rs13447075,rs2648862,rs2720709) between two groups.Conclusion PVT1 rs2648875 may contribute to the susceptibility of DN in chinese people and the others PVT1 SNPs (rs10808565,rs13447075,rs2648862,rs2720709) may not be Chinese susceptibility gene in DN.

Objective To investigate the relationship between the right-to-left shunt(RLS)detected with contrast-enhanced transcranial Doppler (c-TCD) and recurrent stroke in patients with cryptogenic stroke.Methods The consecutive patients w ith ischemic stroke w ere enrol ed. The patients w ith cryptogenic stroke w ere screened according to the TOAST criteria. They w ere divided into either a RLS positive group or a RLS negative group according to the c-TCD findings, and then they w ere fol ow ed up for a period of one year. They w ere also divided into a recurrent group and a non-recurrent group according to w hether they had recurrence or not. Results A total of 118 patients w ith cryptogenic ischemic stroke w ere enrol ed, including 46 in the RLS positive group, 72 in the RLS negative group, 10 in the recurrent group, and 108 in the non-recurrent group. There w ere no significant differences in demographic and baseline data betw een the RLS negative group and the RLS positive group. There w ere significant differences in RLS positive rate (7/10 vs.39/108; P=0.046) and proportion of patients with server RLS (2/10 vs.1/108; P=0.019) betw een the recurrent group and the non-recurrent group. Multivariate logistic regression analysis show ed that the positive RLS w as an independent predictor of recurrent stroke (odds ratio 4.896, 95% confidence interval 1.135-21.120;P=0.033). Conclusions The positive RLS may be an independent risk factor for the recurrence in patients w ith cryptogenic ischemic stroke.

Objective: To study the feasibility, safety and aesthetics of laparoscopic cholecystectomy using a single-port through the umbilicus in patients with chronic cholecystitis with cholecystolithiasis. Methods: From Jan 2007 to Jun 2017, the clinical data of 4790 patients who underwent single-port, 4 426 patients conventional three-ports, and 3 304 patients two-ports laparoscopic cholecystectomy were retrospectively studied. Results: There were no death in all the three groups. There were no significant differences in the incidences of postoperative bleeding, bile leakage, biliary tract injury and other significant short-term complications (all P>0.05). The operation time of transumbilical single-port laparoscopic cholecystectomy was significantly longer than that of two-ports and three-ports laparoscopic cholecystectomy [(35.3±9.0)min vs. (28.4±7.2)min vs. (23.3±6.4)min, P<0.05]. Looking only in a single year, there was no significant difference in the operation time of the three groups in the year 2017 (P>0.05). There were no significant differences among the three groups in intraoperative blood loss, first postoperative passing of flatus, postoperative pain, and length of hospital stay (all P>0.05). The satisfaction score of surgical scar in the single-port group was higher than that in the two-ports and three-ports groups [(9.6±1.6) vs. (7.6±1.9) vs. (6.7±2.0), P<0.05]. Conclusions Transumbilical single-port laparoscopic cholecystectomy was safe and feasible, with good aesthetics and other advantages. It was more difficult than the traditional laparoscopic technique. After the learning curve, the operation time could be comparable to the three-ports technique.

Despite the deepening of research on breast cancer,improving of treatment techniques,there are still many patients will appear local-regional recurrence after surgery.For patients with local recurrence after radical mastectomy,according to whether the postoperative radiotherapy performed,prognosis and treatment protocols are absolutely different.As for patients with local recurrence after breast-conserving surgery,more and more studies have shown that lumpectomy (secondary breast conserving surgery) combined with brachytherapy can achieve a similar effect with radical surgery in recent years,so it is a worth considering treatment protocol.

Objectives:This study aims to investigate the impact of different Low-Density Lipoprotein cholesterol(LDL-C)levels on progression of intermediate coronary stenosis,and the associated risk factors leading to the progression of such lesions. Methods:Data were collected on 219 consecutive patients admitted at the Fuwai Central China Vascular Hospital from January 2020 to February 2021,underwent angiographic examinations and diagnosed with intermediate coronary stenosis,with at least one follow-up angiography after 11 months.Offline quantitative flow ratio(QFR)analysis was performed on these cases.Patients were divided into two groups:LDL-C controlled group(LDL-C<1.8 mmol/L,148 patients with 191 vessels)and LDL-C uncontrolled group(LDL-C≥1.8 mmol/L,71 patients with 98 vessels).Coronary artery QFR and anatomical indicators such as minimal lumen diameter,minimal lumen area,percentage diameter stenosis,percentage area stenosis were compared within and between the groups.Further analysis was performed to identify influencing factors leading to changes in coronary physiological parameters derived from QFR. Results:Within the LDL-C controlled group,there was no significant difference in the QFR values of the vessels compared to baseline(P>0.05),whereas in the LDL-C uncontrolled group(P<0.05),a notable decline in QFR was observed.Patients in the LDL-C controlled group had lower rates of maximum diameter and area stenosis and higher minimum lumen diameter and area(all P<0.05).Through multifactorial Logistic regression analysis,it was found that a body mass index＞28 kg/m2,LDL-C≥1.8 mmol/L,and a history of myocardial infarction were independent risk factors leading to the decline in QFR(all P<0.05). Conclusions:It was found that patients in the LDL-C controlled group had higher coronary artery QFR,minimum lumen diameter and area,lower rates of maximum diameter and area stenosis.

Objective:To investigate the influence of varied oxygen (O 2) concentration environments on the phenotypic transformation of pulmonary artery smooth muscle cells (PASMC) and the mechanism of pulmonary hypertension. Methods:Primary rat PASMC were isolated and cultured through the process of enzymatic digestion. Following identification, the stable passaged PASMC were subjected to a 6-hour incubation in sealed containers with normal O 2 content (group C) and relative O 2 content comprising 55% (group H55), 75% (group H75), and 95% (group H95). mRNA and protein expression of α-Actin (α-SMA), smooth muscle 22α (SM22α), osteopontin (OPN), and matrix metalloproteinase-2 (MMP-2) were measured using real-time quantitative PCR and western blot analysis. Results:The H55 group displayed no significant difference from the C group in terms of mRNA and relative protein expression levels for α-SMA, SM22α, OPN, and MMP-2 (all P>0.05). On the other hand, groups H75 and H95 exhibited a reduction in mRNA and relative protein expression of α-SMA and SM22α, along with an increase in mRNA and relative protein expression of OPN and MMP-2 when compared with both the C and H55 groups (all P<0.05). The H95 group showed a higher relative mRNA expression of MMP-2 as compared to the H75 group ( P<0.05). Conclusions:Oxygen concentration environments of 75% or higher can serve as the foundation for the pathogenesis of pulmonary hypertension, essentially by inducing a phenotypic transformation in PASMC towards adopting a robust secretory function. This induction is contingent upon the concentration of oxygen present.
