ABSTRACT

Objective:To explore the efficacy of precision hepatectomy in the treatment of single hepatocellular carcinoma with microvascular invasion (MVI) of and the risk factors of positive incisal margin after operation.Methods:The clinical data of 212 patients with single hepatocellular carcinoma with MVI treated in Affiliated Hospital of Panzhihua University from July 2016 to July 2019 were analyzed retrospectively. 152 patients were treated with precision hepatectomy and 60 patients with traditional hepatectomy. According to the pathological results of postoperative liver resection, the patients treated with precision hepatectomy were divided into two groups: negative group ( n=129) and positive group ( n=23). The operation-related indexes, postoperative complications and disease-free survival rate of precision hepatectomy and traditional hepatectomy were compared, and the general data of patients with negative and positive liver cutting edge were compared. multivariate analysis of the factors affecting the positive liver cutting edge after operation; to construct a line chart prediction model to predict the positive liver cutting edge after operation, and to evaluate its predictive efficiency. Normally distributed measurement data are represented by mean±standard deviation ( Mean± SD), independent t-test is used for comparison between groups; count data are represented by the number of cases and percentages, and χ2 test is used for comparison between groups. Results:The operative time, intraoperative blood loss, postoperative hospital stay, positive rate of surgical margin, total incidence of postoperative complications, AFP negative conversion rate 6 months after operation, and 1-year disease-free survival rate of precision hepatectomy were (328.62±38.74) min, (496.83±59.76) mL, (15.28±3.61) d, 15.13% (23/152), 3.95% (6/152), 81.58% (124/152), 67.11% (102/152), respectively. The mean values of traditional hepatectomy were (315.29±40.95) min, (681.46±58.27) mL, (23.87±4.65) d, 28.33% (17/60), 21.67% (13/60), 66.67% (40/60) and 46.67% (28/60), respectively, the difference was statistically significant ( P<0.05). Univariate analysis showed that the positive liver resection margin after precision liver resection was related to the maximum diameter of the tumor, vascular tumor thrombus, TNM staging, BCLC staging, liver cirrhosis, AFP 2 months after surgery, and the distance between the tumor and the resection margin ( OR=3.645, 5.248, 4.285, 4.462, 3.883, 3.964, 3.872; 95% CI: 2.875-4.415, 4.426-6.070, 3.271-5.299, 3.354-5.570, 3.062-4.704, 3.248-4.680, 2.987-4.757; P<0.05). Maximum tumor diameter >5 cm, vascular tumor thrombus, TNM stage Ⅲ, BCLC stage C, liver cirrhosis, postoperative AFP ≥20 μg Uniql, the distance between the tumor and the resection margin was <1 mm were the risk factors of positive incisal margin after precision hepatectomy in patients with single liver cancer with MVI( OR=6.685, 8.425, 7.758, 7.854, 7.124, 7.246, 6.926; 95% CI: 5.828-7.542, 7.6385-9.212, 6.926-8.590, 7.062-8.646, 6.583-7.665, 6.618-7.874, 6.028-7.824; P<0.05). The constructed line chart prediction model had better differentiation and higher accuracy. Conclusions:Precision hepatectomy in the treatment of single hepatocellular carcinoma with MVI has the advantages of less intraoperative bleeding, faster postoperative recovery, less postoperative complications, low positive rate of liver incisal margin and high disease-free survival rate. The construction of a risk prediction model with positive surgical margin provides a reference for improving the survival rate of patients in clinic.

ABSTRACT

OBJECTIVE@#To investigate the regulatory effect of metformin on regulatory T cells (Treg) in acidic environment.@*METHODS@#CD4 CD25 Treg cells were obtained by magnetic bead sorting. Treg and conventional T cells (Tcon) cells were cultured for 24-72 h in pH 7.4 or pH 6.7 medium, and the cell proliferation, apoptosis and Foxp3 expression were detected by flow cytometry. Real-time PCR was used to detect the expression levels of the genes related with glucose metabolism. Thirty-two C57BL/6 male mouse models bearing subcutaneous prostate cancer xenograft derived from RM-1 cells were randomized into 4 equal groups for treatment with PBS, metformin, tumor vaccine, or both metformin and the vaccine. The treatment started on the 4th day following tumor cell injection, and metformin (100 mg/kg) or PBS was administered by intraperitoneal injection on a daily basis; the vaccine was intramuscularly injected every 4 days. The tumor size was continuously monitored, and the mice were euthanized on day 25 after tumor implantation to obtain tumor and blood samples. Flow cytometry was used to detect the changes in CD4, CD8, CD4Foxp3 cell subsets in the tumor tissue and peripheral blood.@*RESULTS@#Treg cells showed significantly enhanced proliferation ( < 0.05) while the proliferation of Tcon cells was suppressed in acidic medium ( < 0.001). Treg cells cultured in acidic medium showed significantly increased expressions of OXPHOS-related genes pgc1a ( < 0.001) and cox5b ( < 0.01), which did not vary significantly in Tcon cells in acidic medium. Treg cells exhibited significantly decreased apoptosis in acidic medium ( < 0.01) with increased Foxp3 cells ( < 0.001) and intracellular alkaline levels ( < 0.01). Metformin obviously reversed the acid tolerance of Treg cells without producing significant effect on Tcon cells. In the animal experiment, both metformin ( < 0.05) and vaccine ( < 0.01) alone reduced the tumor volume, but their combined treatment more potently reduced the tumor volume ( < 0.001). Metformin alone did not obviously affect CD4 cells or CD8 cells but significantly decreased the percentage of CD4Foxp3 ( < 0.05); the vaccine alone significantly increased CD4 cells and CD8 cells ( < 0.001) and also the percentage of CD4Foxp3 cells ( < 0.05). The combined treatment, while reducing the percentage of CD4Foxp3cells to a level lower than that in the vaccine group ( < 0.01), produced the strongest effect to increase CD4 cells and CD8 cells ( < 0.01).@*CONCLUSIONS@#Metformin can inhibit the proliferation and function of regulatory T cells in an acidic environment and enhance the effect of tumor vaccine by reducing the proportion of Treg cells to achieve the anti-tumor effect.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the efficacy of combined laparoscopic-endoscopic lower esophageal sphincterotomy and modified Dor fundoplication for cardiochalasia patients.</p><p><b>METHODS</b>Clinical 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.</p><p><b>RESULTS</b>Combined 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.</p><p><b>CONCLUSION</b>Combined laparoscopic-endoscopic lower esophageal sphincterotomy and modified Dor fundoplication is an effective and safe surgical procedure for cardiochalasia with minimal invasion and fast recovery.</p>

ABSTRACT

Objective: To investigate the effects and safety of recombinant human brain natriuretic peptide [rhBNP] in the treatment of elderly acute myocardial infarction induced cardiac failure


Methods: One hundred and forty-six patients who were diagnosed as elderly acute myocardial infarction induced cardiac failure in the hospital from July 2014 to July 2015 were selected. They were divided into a test group and a control group, 73 each. Patients in both groups were given conventional treatment such as stabilization of atherosclerotic plaques, anti-platelet and remodeling and reversion of myocardium. The curative effects and the incidence of adverse reactions of the two groups were observed


Results: The overall efficacy of the test group and the control group was 87.7% and 65.8% respectively, and the difference had statistical significance [P<0.05]. The heart rate, urine volume, n-terminal probrain natriuretic peptide level and left ventricular ejection fraction [LVEF] of both groups significantly improved after treatment, and the improvement of the test group was superior to that of the control group [P<0.05]. The serum creatinine of the test group remarkably reduced after treatment [P<0.05]. The incidence of hypotension and arrhythmia of the test group was lower than that of the control group during hospitalization period [P<0.05]


Conclusion: rhBNP can effectively relieve the clinical symptoms, cardiac function indexes and hemodynamic indexes of patients with elderly acute myocardial infarction induced cardiac failure, with a high safety. It can be extensively applied in the treatment of acute myocardial infarction in combination with cardiac failure

ABSTRACT

Rheumatoid arthritis (RA) is a chronic autoimmune disorder primarily occurred in small joints.Our previous studies suggested that sufficient lymphatic drainage was favorable for the recovery of RA.This study aimed at exploring the effect of Er Chen combined with Tao Hong Si Wu Tang (ECSWT) on RA in TNF transgenic (TNF-Tg) mice.Ten-week old TNF-Tg mice and WT littermates were detected with indocyanine green-nearinfrared (ICG-NIR) lymphatic imaging system before and after accepting the 12-week intragastric administration of ECSWT.All ankle joints were assessed by micro-CT scanning.According to three dimensional images of Micro-CT,it was found that the ankle joints in the TNF-Tg group were much eroded compared with the control group.The bone mass and structure were protected after the treatment of ECSWT.ICG-NIR results showed that lymphatic clearance rate of the TNF-Tg group decreased compared with those of the control group.In comparison with the TNF-Tg group,ECSWT promoted the repair of lymphatic function.Compared with the control group,the pulse value of the TNF-Tg group declined;while this condition could be rescued by ERSWT.In conclusion,ECSWT mitigated bone erosion of astragalus bone area in TNF-Tg mice in contrast to the saline mice,while promoted the pulse value and clearance of lymphatic vessels afferent from footpad to popliteal lymph node,implying that ECSWT was a promising agent for treating RA through its promoting lymphatic drainage function effects.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical advantage of the application of modified Roux-en-Y reconstruction after totally laparoscopic total gastrectomy.</p><p><b>METHODS</b>Clinical data of 36 patients who underwent totally laparoscopic total gastrectomy with Roux-en-Y reconstruction by one medical team for gastric adenocarcinoma between January 2014 and December 2014 in the Second Hospital of Jilin University were retrospectively analyzed. Patients were divided into classic Roux-en-Y group (CRY, 16 cases) and modified Roux-en-Y group (MRY, 20 cases) according to reconstructive methods. The data concerning the intraoperative and postoperative situation in two groups were compared.</p><p><b>RESULTS</b>Operation was successfully completed in all the cases without conversion to laparotomy. Compared to CRY group, MRY group had shorter mean operative time [(260.9 ± 21.2) min vs. (287.9 ± 19.0) min, P=0.000], shorter mean reconstruction duration [(32.4 ± 9.2] min vs. (45.4 ± 13.2) min, P=0.001] and less intraoperative bleeding [(50.9 ± 23.5) ml vs. (67.0 ± 20.5) ml, P=0.000]. Jejunum mesentery dissection and jejunum resection were not necessary in MRY group. However, there were no significant differences in lymph nodes harvested, time to flatus, hospital stay and postoperative complications between two groups.</p><p><b>CONCLUSIONS</b>As compared to classic Roux-en-Y reconstruction, the modified Roux-en-Y reconstruction can simplify the surgical procedures and achieve similar efficacy. It is feasible and safe, and worth further promotion in clinical practice.</p>

ABSTRACT

Objective to measure the percentage of th22 cells and evaluate the levels of plasma interlukin-22(IL-22)in human peripheral blood, so as to determine their clinical significance in primary Sj?gren′s syndrome(pSS). Methods Patients with pSS were divided into three subgroups based on severity of labial gland involvement:mild,moderate and severe. Healthy people served as controls. the percentage of th22 cells and the lev-els of IL-22 in human peripheral blood from pSS patients and healthy controls were measured and compared. Results Compared to healthy con-trols,pSS patients had significantly higher percentage of th22 cells and higher plasma IL-22 levels(P < 0.05). Among pSS patients,the more seri-ous illness they had,the higher percentage of th22 cell and levels of IL-22 were observed. Severe patients had higher percentage of th22 cells and IL-22 levels than moderate patients(P < 0.05),and moderate patients had higher percentage of th22 cells and IL-22 levels than mild patients(P <0.05). Conclusion Increased peripheral IL-22-secreting th22 cells are detected in primary Sj?gren′s syndrome,which have a close association with disease severity. these data suggest that th22 and its released cytokine IL-22 may be considered as potential valuable biomarkers for severity of pSS,which may provide a novel therapeutic target for treatment.

ABSTRACT

Primary care physicians' visit services for diabetes management are now widely delivered in China's rural public health care. Current studies mainly focus on supply but risk factors from patients' view have not been previously explored. This study aims to present the utilization of rural primary care physicians' visit services for diabetes management in the last 12 months in southwestern China, and to explore risk factors from patients' view. This cross sectional study selected six towns at random and all 385 diabetics managed by primary care physicians were potential participants. Basing on the inclusion and exclusion criteria, 374 diabetics were taken as valid subjects and their survey responses formed the data resource of analyses. Descriptive indicators, chi[2] contingency table analyses and Logistic regression were used. 54.8% respondents reported the utilization of visit services. According to the multivariate analysis, the positive factors mainly associated with utilization of visit services include disease duration [OR=1.654], use of diabetic drugs [OR=1.869], consulting diabetes care knowledge [OR=1.602], recognition of diabetic complications [OR=1.662], needs of visit services [OR=2.338]. The utilization of rural primary care physicians' visit services still remains unsatisfactory. Mass rural health policy awareness, support, and emphasis are in urgent need and possible risk factors including disease duration, use of diabetic drugs, consulting diabetes care knowledge, recognition of diabetic complications and needs of visit services should be taken into account when making rural health policy of visit services for diabetes management in China and many other low- and middle-income countries

ABSTRACT

Objective To investigate the indications and clinical effect of the low-big hole choledochoduodenostomy. Methods Two hundred and ninty-eight patients, had bile duct stone accompanied with common bile duct lower segment stenosis, were prospectively enrolled into the study and randomly divided into the low-big hole choledochoduodenostomy (improved CD ) group (n = 148 ) and the Roux-en-Y choledochojejunostomy (CJ) group (n = 150). Their perioperative period and long term effect indices were recorded and compared. Results Perioperative period indices:The time of cholangio-jejunostomy was much shorter in improved CD group than the CJ group ([31.0±10.5] min vs [53.0±12.3] min, P<0.001);The anastomotic leakage was significantly less in improved CD group than the CJ group (2 vs 9, P < 0. 001 ). The long term effect indices: The occurrence of peptic ulcer (3 vs 15 ) and the bile duct cecum or blind loop syndrome (5 vs 158) were significantly lower in group improved CD group than CJ group (Ps<0.01);The occurrence of bile duct backflow (70 vs 42) was significantly higher in improved CD group than CJ group (P<0. 0l). Conclusion The clinical effect of the low-big hole choledochoduodenostomy gastrointestinal had excellent effect for bile duct stone accompanied with common bile duct lower segment stenosis, especially for old,weak and critical patients,and it can not be replaced by the Roux-en-Y choledochojejunostomy.

ABSTRACT

Purpose To prepare streptavidin-tagged mouse interleukin-4(mIL-4-SA)bifunctional fusion protein and to study on its bioactivity.Methods The mIL-4 gene was cloned by RT-PCR and cloned into pET21 vector to get mIL-4-SA-pET21 expression plasmid.The mIL-4-SA fusion protein was expressed in BL21 (DE3)host bacteria and purified through the Ni-NTA affinity chromatography and refolded by dilution and dialysis.The effect of mIL-4-SA fusion protein on mouse thymocytes proliferation was evaluated by MTY.Flow cytometric analysis was performed to detect the mIL-4-SA fusion protein on the biotinylated B16F10 tumor cells.Results The mIL-4-SA-pET21 vector was successful by constructed and the mIL-4-SA fusion protein was expressed in BL21(DE3)at about 35%of total bacterial proteins.The purity of mIL-4-SA Was about 95% through Ni-NTA.The mIL-4-SA fusion protein exhibited bifunctional activities,i.e.,stimulative effect for mouse thymocyte proliferation and SA-mediated high-affinity binding to biotinylated cell surfaces(anchoring modified rate Was about 96.69%).Conclusion The mIL-4-SA fusion protein was expected to be developed for the treatment of tumors.

ABSTRACT

Objective To investigate the effects of the wound isolation in prevention of abdominal wound infection. Methods 2549 patients who bearded abdominal operation in 3 years in our hospital were randomly divid-ed into wound isolation group (n=1300) and control group(n=1249). The wound infection rates were summarized by operation ways and major influencing factors. Results The overall wound infection rate of control group and wound isolation group was 5.9% (76/1300) and 2.6% (32/1249). The infection rate was 13.4% (40/300) and 3.1% (9/280) in gallbladder resection, 14.7 % (24/165) and 3.5 % (6/159) in radical operation for carcinoma of colon, 13.6% (15/108) and 3.2% (13/114) in intestine block operation, 9.6% (18/187) and 1.8% (3/169) in stomach resection (P<0.01);The infection rate was 9.3% (13/145)and 2.9% (4/153)in biliary exploration, 14.6% (8/55) and 1.8% (1/56) in WHIPPLE, 10.6% (9/85) and 2.3% (2/88) in cholecystectomy (P<0.05);The infection rate was 6.3% (6/95) and 2.3% (2/86) in liver resection, 5.3% (5/95) and 1.2% (1/87) in spleen resection, 4.6% (3/65) and 1.8% (1/57) in porto-azygos venous disconnection (P>0.05). The wound infection rate of type Ⅰ resection of control group and wound isolation group was 2.0% (6/305) and 1.4% (4/280) (P> 0.05);The infection rate of type Ⅱ and Ⅲ resection was 7.0% (70/995) and 2.9% (28/969), for old man (≥60) was 12.6% (36/286) and 3.6% (10/279), the emergency operation was 10.0% (38/381) and 2.8% (10/362), the operation time ≥3 h was 9.0% (39/435) and 2.8% (12/426), with diabetes was 14.5% (21/145) and 4.9% (6/123), with obesity was 12.3% (40/325) and 3.9% (12/310), with malnutrition was 8.5% (39/458) and 3.2% (14/433), with cancer was 8.6% (40/465) and 3.0% (15/496) (P<0.01).;undergoing unemergency operation was 4.1% (38/919) and 2.5% (22/887),for yong persons (<60) was 3.9% (40/1014) and 2.3% (22/970), with operation time<3 h was (37/865) and 2.4% (20/823), without diabetes was 3.9% (45/1155) and 2.3 % (26/1126), without obesity was 3.7 % (36/975) and 2.1% (20/939), without malnutrition was 4.4% (37/842) and 2.2% (18/816)and without cancer was 4.3% (36/835) and 2.3% (17/753) (P<0.05). Conclu-sions The wound isolation can decrease the wound infection rates by reducing the chance of bacterial contamina-tion.
