Objective To detect the expressions of interleukin-17(IL-17) and interleukin-23(IL-23) in esophageal tissues of rats with reflux esophagitis(RE) and explore the role of IL-23/IL-17 axis in the pathogenesis of RE.Methods Thirty SD rats were randomly divided into 3 groups,namely,control group,sham-operated group and model group.RE was induced by adopting partial pyloric ligation plus cardiomyotomy.Then rats in each group were fasted for 24 h but had free access to water.They were fed 24 h after operation.Four weeks later,rats were killed and pathological changes of esophagus mucous membrane were observed by HE staining in each group.The expressions of IL-23p19 and IL-17 mRNA in esophageal tissues were examined by real-time fluorescent quantitative reverse transcriptase polymerase chain reaction(RT-FQ-PCR).IL-17 protein content in esophageal tissues was measured by ELISA.Results After four weeks,compared with control group,model group had significant pathological changes of esophagus mucous membrane.Expressions of IL-23p19 and IL-17 mRNA in the esophageal tissues of model group were significantly higher than those of the other two groups;the content of IL-17 protein was significant higher in model group than in the other two groups.There were no significant differences between control group and sham-operated group.Conclusion IL-23/IL-17 axis is an important cellular factor involved in the pathogenesis of RE and may be involved in the chronic inflammation of RE.

Objective To summarize the experience in the diagnosis and treatment for solidpseudopapillary tumors of the pancreas (SPTP). Method In this study, 27 cases of SPTP from September 2000 to June 2007 were retrospectively analyzed. Results The median age of these 27 cases was 26 years. There were 26 females and 1 male. Epigastric pain was complained in 16 cases, abdominal aponia mass in 11 cases. Tumour marker level was within normal range. Ultrasonic manifestation usually shows cystic and solid lesion without blood signal. Lesions were typical with high blood supply in enhanced CT scan, cystic and solid component confounding in it. MRI revealed low-middle signal in T1 and middle-high signal in T2. Pancreaticoduodenectomy was performed in 9 cases, pancreatic local excision and pancreaticojejunostomy were performed in 4 cases, pancreatic local excision was performed in 6 cases, Distal pancreatectomy and spleen resection were performed in 8 cases. Post-operative pathology shows local lesion in 12 cases, invading the pancreatic parenchyma in 14 cases and intravascular tumor thrombi and lymphnode metastasis in 1 case. All cases were followed up with an average period of 26.1 months. There was no recurrence nor metastasis. Conclusion Solid-pseudopapillary tumor of the pancreas has a low malignant potential, affecting primarily young women. It has no typical clinical appearance. Enhanced CT scanning has the relative characteristic imaging. Complete resection usually results in long-term survival.

Objective To investigate the clinical characteristics, diagnosis, treatment and prognosis of hepatic angiomyolipoma (HAML). Methods The clinical data of 14 patients with hepatic angiomyolipoma admitted in our hospital from 1989 to 2007 were analyzed retrospectively. Result There were 4 male patients and 10 female patients. Median age was 41 years old. The lesions located in right lobe in 8 patients, and in left lobe in 6 patients. B-US was taken in 12 patients before operation, and other examinations included CT in 8 patients, MRI in 7 patients and angiography in 2 patients. Five patients were diagnosed with HAML by imagine features. Fine needle biopsy was taken in 1 patient with no definite diagnosis. All patients underwent resection and got the histopathologic diagnosis with HAML. All specimens were HMB-45 positive. S-100 and SMA were tested in 7 and 6 patients respectively, and were positive in all those patients. All cases were followed up for 6 months to 18 years (median time was 3 years). 13 patients were still alive without recurrence and 1 patient died of postoperative DIC and heart failure. Conclusion There was marked female predominance in HAML. Imaging features are helpful for preoperative diagnosis of HAML, but correct diagnosis was achieved in only a fraction of patients. HMB-45 positive was definitive proof for histopathologic diagnosis of HAML. Hepatectomy was an effective treatment for HAML.

Objective To investigate the suitable treatment of post operative anastomotic recurrence after anterior resection of rectal cancer and analyze the relationship between different kinds of therapy with prognosis. Methods The clinical data of 41 cases of local recurrent rectal cancer after anterior resection admitted in our hospital from 1999 to 2009 were analyzed retrospectively. The median survival time and survival rate were calculated by Life Tables method. The influence of different kinds of treatment to prognosis was evaluated by Kaplan-Meier method and the variability was analyzed by Log-rank method. P <0.01 means statistical significance. Results Thirty-three (80.5 %) of 41 patients were recurrent in the first 3 years and the median survival time was 23 months. Seventeen (41.5 %) of 41 patients underwent radical R0 resection. The median survival time of radical resection patients and non-radical resection ones were 49 months and 18 months, respectively, and the difference was significant (χ2=12.245, P=0.000). Thirty-one patients with radiotherapy and/or chemotherapy showed a statistically longer median survival time than the other 10 patients without these adjuvant treatment (39 months and 9 months, respectively) (χ2=17.533, P =0.000). Conclusion Most post operative anastomotic recurrent of rectal cancer cases occurs in the first 3 years after primary surgery. Radical resection, radiotherapy and chemotherapy can improve the prognosis.

Objective To evaluate the impact of cardiopulmonary resuscitation (CPR) training on the willingness to perform on-site rescue for patients with apnea and cardiac arrest. Methods Through questionnaire survey, the analyses on the differences in the results of evaluating various indicators in CPR Willingness Questionnaire in 364 willingness (including 14 recurrent training personnel) of Yunnan Emergency Center from January 2017 to June 2018 before and after CPR training were carried out in order to observe the impact of training on willingness CPR willingness. Results A total of 364 questionnaires were distributed and 364 valid questionnaires were recovered, with a recovery rate of 100%. Compared with those before the CPR training, the analyses of the contents of the questionnaire showed that the proportions of following 6 types of volunteer who were reluctant to implement CPR on site begore training were significantly lower after CPR training [no confidence in their own operational skills: 20.3% (74/364) vs. 83.2% (303/364), being impossible to identify the patients requiring CPR: 25.5% (93/364) vs. 87.1% (317/364), fear of mouth-to-mouth artificial respiration to contract infectious diseases: 30.2% (110/364) vs. 82.4% (300/364), worried about chest compressions leading to bone fractures: 23.3% (85/364) vs. 86.8% (316/364), worried about the inaccurate positioning of chest compressions: 12.4% (45/364) vs. 82.4% (300/364) and fear of taking legal responsibility: 14.3% (52/364) vs. 89.8% (327/364)], and the differences were statistically significant (all P < 0.05); after training, the following 3 kinds of proportions of carrying out CPR were much higher than those before training [volunteers were willing to implement CPR on site for strangers: 83.2% (303/364) vs. 54.9% (200/364), volunteers were willing to implement CPR on site for friends, colleagues, classmates and other acquaintances: 83.5% (304/364) vs. 58.2% (212/364), volunteers were willing to implement CPR on site for family members: 84.6% (308/364) vs. 61.8% (225/364)], the differences being statistically significant (all P < 0.05). Conclusion CPR training for volunteers can improve their willingness to perform on-site rescue for patients with apnea and cardiac arrest, but there are still partial barriers of CPR willingness for strangers.

OBJECTIVETo study the influence of SGHWJN particles on inflammation and the mediators of inflammation in esophageal tissues of rat with reflux esophagitis.

METHODFifty SD rats were randomly divided into 5 groups, namely, a control group, a sham-operated group, a model group, a SGHWJN particles group and a PPI group. Reflux esophagitis was induced by adopting partial pyloric ligation plus cardiomyotomy. One week later, the rats were orally administered twice daily for 28 days. Pathological changes of esophagus mucous membrane were evaluated by using HE staining and Harry S. Cooper's method in every groups. MDA and SOD contents in esophageal tissues were measured by colorimetric method. Expression of TNF-alpha in esophageal tissues were examined by real-time fluorescent quantitative reverse transcriptase polymerase chain reaction (RT-FQ-PCR) with SYBR Green.

RESULTModel group, esophageal inflammation scores, expression of TNF-alpha in esophageal tissues and MDA contents compared with the normal group and sham operation group were significantly higher (P < 0.05). SOD contents in the esophageal tissues of the model group was significantly lower than that of control group and sham-operated group (P < 0.05). SGHWJN particles group and PPI group of esophageal tissue inflammation scores, expression of TNF-a in esophageal tissues and MDA levels than those in model group decreased significantly (P < 0.05). SOD content was significantly higher than that of model group (P < 0.05), SGHWJN particles group and PPI group showed no statistically significant difference between the above-mentioned indicators. The above-mentioned indicators showed no statistically significant difference between the normal group and sham-operated group. MDA content and expression of TNF-alpha in esophageal tissue was positively correlated with inflammatory scores of model group (r = 0.813). Model group esophageal tissue SOD content and inflammation scores were negatively correlated (r = -0.847). Esophageal tissue SOD levels were negatively correlated with MDA levels (r = -0.863).

CONCLUSIONSGHWJN particles can effectively inhibit inflammation in rat with reflux esophagitis through regulating TNF-alpha, SOD and MDA.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.

In the present study, the performance of the liquid nitrogen frozen and thinned bovine pericardium was studied and compared with the porcine pericardium. The microstructure and mechanical properties of the bovine pericardium were observed and tested by hematoxylin-eosin (HE) staining and tensile test respectively. In all conditions, porcine pericardium was selected as a control group. The results showed that there was little difference in the performance of bovine pericardium after being frozen by liquid nitrogen. The secant modulus and ultimate strength of the thinned bovine pericardium were similar to those of porcine pericardium, however, the elastic modulus was a little higher than porcine pericardium. The study suggested that the performance of the thinned bovine pericardium was similar to those of porcine pericardium. It was easy for the thinned bovine pericardium to obtain a relatively ideal thickness and expected performance, therefore, the thinned bovine pericardium can be used as the materials of transcatheter aortic valve leaflets.
