Objective To investigate the effects of esculin and digitalisglycosides eye drops combined with 532 laser on the treatment of diabetic retinopathy.Methods 65 cases(130 eyes)with diabetic retinopathy in our hospital from November 2012 to November 2015 were selected and divided into observation group(33 cases)and control group(32 cases).The control group was treated with 532 laser treatment,and the observation group was combined with esculin and digitalisglycosides eye drops.Two groups of treatment were one months.Therapeutic effect of two groups were compared,improvement of visual acuity,retinal hemorrhage,exudation,edema absorption time,before and after macular retinal thickness changes.Results After treatment,the total efficiency of the observation group(96.97％)was higher than the control group(75.00％),the difference was statistically significant(P<0.05),the visual acuity of the observation group was significantly higher than that of the control group,and decreased significantly less than the control group,the difference was statistically significant(P<0.05),the retinal hemorrhage,exudation and edema were observed in the observation group faster than the control group,the difference was statistically significant(P<0.05),the macular retinal thickness decreased in the two groups after treatment,the difference was statistically significant(P<0.05),the retinal thickness of the macular area was lower in the observation group than in the control group,the difference was statistically significant(P<0.05).Conclusion Esculin and digitalisglycosides eye drops combined with 532 laser in the treatment of diabetic retinopathy has significant effect,and can reduce the macular retinal thickness,which has important clinical significance.

Objective To investigate the feasibility of combined laparoscopic and thoracoscopic esophagectomy for esophageal carcinoma and gastro-esophageal anastomosis in right thoracic cavity.Methods We retrospectively analyzed the clinical data of 38 patients who underwent esophagectomy for esophageal carcinoma and gastro-esophageal anastomosis in right thoracic cavity from October 2011 to August 2012.To remove the stomach in laparoscopic and the esophagus in thoracoscopy.The main portion of a gastric conduit is created using three to four firings of a linear stapler(Ethicon Endo-surgery,Cincinati,OH) and jejunum stoma.Gastric conduit was pulled into the chest cavity and anastomosed to the esophagus.Results The average operative time was 280 minutes,the mean operative blood loss was 120 ml.No patient required laparotomy.No pulmonary complications or anastomotic leaks occurred.One had gastric retention,another one had chylous hydrothorax.All patients were cured,no one dead in hospital.Conclusion Combined laparoscopic and thoracoscopic esophagectomy for esophageal carcinoma and gastro-esophageal anastomosis in right thoracic cavity is technically feasible and safe,minimized trauma,less operative blood loss and quick recovery.

BACKGROUND: Studies have shown that tranexamic acid can effectively reduce postoperative blood loss in patients with total knee arthroplasty. There are many means to inject tranexamic acid (intra-articular injection, intravenous injection and their combination). Which is the best way has no conclusion.
OBJECTIVE: To explore whether all three ways (intra-articular injection, intravenous injection and their combination) to inject tranexamic acid can all effectively reduce the bleeding after total knee arthroplasty.
METHODS:103 patients undergoing unilateral total knee arthroplasty from December 2014 to December 2015 were enrolled in this study. The patients were allocated into four groups according to injection way. In the intra-articular injection group, 2 000 mg of tranexamic acid was given through the intra-articular injection after incision suture. In the intravenous injection group, 1 000 mg of tranexamic acid was given through the intravenous injection at 15 minutes before the use of tourniquet. In the combined modality therapy group, above methods were used. In the blank control group, tranexamic acid was not given.
RESULTS AND CONCLUSION:(1) Total blood loss and blood transfusion rate were less in the intra-articular injection group and combined modality therapy group than in the intravenous injection group (P < 0.05). The total blood loss was more in the intra-articular injection group than in the combined modality therapy group (P > 0.05). The blood transfusion rate was 0% in the intra-articular injection group and combined modality therapy group. (2) Adverse reaction: deep vein thrombosis, pulmonary embolism, wound infection, hematoma or gangrene was not observed in al groups. (3) Results confirmed that intra-articular combined with intravenous injection can reduce effectively postoperative blood loss and the effect is better than separate administration.

Objective To study the indication,feasibility and short-term efficacy of combined thoracoscopic and laparoscopic radical esophagectomy for the treatment of esophageal cancer.Methods Retrospective medical records analysis was conducted for 139 esophageal cancer patients who underwent combined thoracoscopic and laparoscopic esophagectomy in our department from December 2009 to August 2011.The tumors were located in upper esophagus in 16 cases,middle esophagus in 107 cases,and lower esophagus in 16 cases.The surgery started with the thoracoscopic mobilization of thoracic esophagus and lymph nodes dissection,which were followed by the laparoscopic stomach mobilization and gastroesophageal anastomosis in left neck.Postoperative pathological staging identified stage Ⅰ esophageal cancer in 25 cases ( stage Ⅰ a:13 cases,stage Ⅰ b:12 cases),stage Ⅱ esophageal cancer in 71 cases,stage Ⅲ esophageal cancer in 31 cases ( stage Ⅲ a:16 cases,stage Ⅲ b:15 cases) and stage Ⅳ esophageal cancer in 12 cases.Results Except for open conversions in 4 cases (2.9％),all surgical operations were completed smoothly.Postoperative anastomotic leak was found in 6 cases(4.3％ ),chylothorax in 1 case(0.7％ ),arrhythmia in 4 cases(2.9％ ),and dumping syndrome in 1 case( 0.7％ ).All of these complicated cases fully recovered after conservative treatments.Postoperative lung infection was found 11 cases (7.9％),3 of whom required tracheotomy and assisted ventilation and 1 case died as a result of the infection (mortality rate:0.7％ ).Ten cases(7.2％ ) presented with hoarseness postoperatively.Out of the 139 cases,130 cases were successfully followed up with durations ranged from 1 to 20 months,during of time the esophageal cancer spread to liver in 2 cases,celiac lymph nodes in 4 cases,lung in 2 cases,and bone in 1 case.Ten cases died,and all remaining cases remained alive during the follow up.The one-year survival rate was 88.9％ for these cases.Conclusion Combined thoracoscopic and laparoscopic radical esophagectomy is a technically safe and feasible treatment for esophageal cancer.The short-term efficacy results are satisfactory.This technique is indicated not only for early and middle stage esophageal cancer,but also for some of the advanced esophageal cancer cases.

OBJECTIVETo determine the feasibility and efficiency of terminating atrial flutter (AFL) and atrial fibrillation (AF) using synchronous low-energy shocks delivered through a novel transesophageal electric balloon electrode system.

METHODSBy using a novel electric balloon electrode system, we attempted 91 transesophageal cardioversions in 52 patients, to treat 53 episodes of AFL and 38 episodes of AF.

RESULTSOf the 40 patients of AFL that failed to respond to drug therapy, 37 (92.5%) were successfully countershocked to sinus rhythm by transesophageal cardioversion, with a mean energy of (22.70 +/- 4.50) J (20 - 30 J). Of the 19 patients in AF, transesophageal cardioversion was successful in 16 (84.2%) cases, requiring a mean delivered energy of (17.38 +/- 8.58) J (3 - 30 J). There were no complications such as heart block or ventricular fibrillation, and no evidence of esophageal injury.

CONCLUSIONSTransesophageal cardioversion using an electric balloon electrode system is an effective and feasible method for the treatment of AFL and AF. It requires low energy and no anesthesia, leads to less trauma, and shows a high cardioversion success rate that may prove valuable in the management of tachyarrhythmias.

OBJECTIVETo investigate the safety and feasibility of forgoing postoperative nasogastric tube decompression in minimally invasive esophagectomy for patients with esophagus carcinoma.

METHODSClinical data of 90 eligible patients who underwent elective minimally invasive esophagectomy in our department from January 2012 to May 2013 by the same surgical team were retrospectively analyzed. Among them, 45 patients did not receive the use of postoperative nasogastric tube decompression and 45 patients received nasogastric tube decompression after operation. The observation parameters included the time to first flatus, the time to intake of fluid diet, the duration of postoperative hospitalization, pharyngalgia, vomiting, and postoperative complications, as well as the need for placing or replacing the nasogastric tube.

RESULTSThe incidence of pharyngalgia was significantly higher in nasogastric tube group (100% vs 44.4%, P<0.001). The time to intake of fluid diet [median 2 d(2-4 d) vs. median 9 d(7-20 d), P<0.001] and the time to first flatus [median 3 d(3-8 d) vs. median 6 d(3-9 d), P<0.001] were all significantly shorter in non-nasogastric tube group as compared to nasogastric tube group. Compared with the nasogastric tube group, the non-nasogastric tube group had shorter postoperative hospital stay (P<0.001). There were no significant differences in the incidence of postoperative complications and vomiting between two groups.

CONCLUSIONMinimally invasive esophagectomy without the use of postoperative nasogastric tube decompression is safe and feasible, which can improve recovery and shorten postoperative hospital stay.

Objective This study aimed to evaluate the prognostic value of regional lymph node spread in patients with stage Ⅱ nasal-type NK/T-cell lymphoma of the upper aerodigestive tract (UADT-NKTCL).Methods From 1987 to 2013,a total of 97 patients with newly-diagnosed stage Ⅱ UADT-NKTCL were retrospectively reviewed.Primary tumors were located in the nasal cavity (n=52) or extranasal UADT sites (n=45).The majority of patients were treated with primary radiotherapy.Sixty-five patients were treated with combined modality therapy (CMT),and 32 patients were treated with radiotherapy alone (n=27) or chemotherapy alone (n=5).The Kaplan-Meier method was used to calculate the survival rate,and the log-rank test was used for survival difference analysis and monovariate prognostic analysis.The Cox regression model was used to multivariate prognostic analysis.Results The 5-year overall survival (OS) and progression-free survival (PFS) rates for all stage Ⅱ patients were 57% and 49%,respectively.The presence of a lower neck lymph node (defined as extension below the caudal border of the cricoid cartilage) was significantly associated with poor outcomes on univariate analysis and maintained significance on multivariate analysis.The median survival for patients with lower neck lymph node was 19.3 months and the 2-,5-years OS rates were 28% and 11%(P=0.000).For stage Ⅱ patients,CMT significantly improved survival.The 5-year OS and PFS rates were 64% and 52% for CMT,compared with 40.4%(P=0.006) and 42% for single modality therapy (P=0.088).Conclusion The level of regional lymph node is a powerful prognostic factor for stage Ⅱ UADT-NKTCL.The involvement of low neck lymph node is significantly associated with poorer survival outcomes.

Objective:To study the clinicopathological features, diagnosis, treatment and prognosis of patients with solid pseudopapillary neoplasm of the pancreas (SPN).Methods:From Jan 2008 to Dec 2017, 112 pathology confirmed SPN patients who underwent surgical treatment at the Fourth Hospital of Hebei Medical University were followed up. The clinicopathological characteristics and diagnosis were analyzed.Results:Most SPN patients were young women, the ratio of male to female is 1∶7. SPN patients have no typical clinical symptoms. The preoperative diagnostic accuracy of SPN was 57.14% with imaging examination. Pathological diagnosis depends mainly on immunohistochemical staining. All patients underwent surgical resection. Follow-up ranged from 4 to 123 months. The mean follow-up time was 49 months. All patients were doing well and no recurrence or metastasis was found.Conclusions:SPN is a rare tumor with low malignant potential. Surgical resection is effective.
