Objective To explore the the application of sternocleidomastoid lateral path for thyroid cancer surgery lateral neck lymph node cleaning.Methods 40 patients with thyroid carcinoma were detected in the lateral neck lymph node cleaning using sternocleidomastoid lateral path(experimental group)and 40 cases of patients with thyroid cancer in the lateral neck lymph node cleaning cleaning scope with traditional operation method(control group),comparing with success rates,operation time,quality of life and incidence of complications.Results Experimental group can achieve the purpose of curing in the operation,operation field showed more clearly,the lymph node zone Ⅱ,Ⅲ,Ⅳ,Ⅴ number (32,58,50,35)were higher than traditional surgery group(17,35,33,20).Experimental group can significantly shorten the operation time[(30.0±1.20)min vs(45.0±3.10)min].The difference of incidence of near and forward future overall complications was statistically significant between the two group(P<0.05).Conclusion Sternocleidomastoid lateral path in thyroid carcinoma in the lateral neck lymph node cleaning can achieve the purpose of curing,significantly improve the lymph node zone Ⅱ,Ⅲ,Ⅳ,Ⅴ,shorten the operation time,reduce the recent and long-term complications and improve patient's quality of life.

Objective To study the methods and outcome of surgical treatment of distal bile duct carcinoma.Methods The clinical data of 51 cases of distal bile duct carcinoma who underwent surgery were analyzed retrospectively.Of them,28 cases received radical pancreaticoduodenectomy,and 23 cases had internal bile duct drainage procedures.Results The total average survival time was 20 months.The mean survival time of radical and drainage operation was 32 months and 8 months respectively.Postoperative 5-year survival rate in radical pancreaticoduodenectomy group was 17.8%,and in drainage group was 0.The outcome of radical pancreaticoduodenectomy group was significantly better than that of internal bile duct drainage procedures group(P

Objective To investigate the mid-term effect of SolitaireAB stent-assisted interventional embolization with spring coils for the treatment of intracranial wide-necked aneurysms. Methods During the period from May 2009 to April 2013, a total of 49 patients with intracranial wide-necked aneurysm (49 aneurysms in total) received SolitaireAB stent-assisted interventional embolization treatment at authors’ hospital. In 41 patients, a total of 41 aneurysms were detected, of which ruptured aneurysm with bleeding was confirmed in 26 and un-ruptured aneurysm in 15. These 41 patients were followed up for 12-48 months. Based on modified Rankin scoring and DSA, CTA or MRA manifestations, the clinical results were evaluated. Results After the embolization treatment, re-bleeding of the aneurysm occurred in 2 cases, cerebral infarction in 3 cases, occlusion of the parent artery in one case and death in one case; the occurrence rate of complications was 14.2%. DSA, MRA or CTA performed at 12 months after the embolization treatment, showed that 32 aneurysms (78.0%) were completely obstructed, which was obviously higher than that observed on DSA performed immediately after the embolization procedure (21 aneurysms, 42.9%), the difference was statistically significant (P=0.02);residue of aneurismal neck was seen in 7 cases (17.1%) and partial occlusion in 2 cases (4.9%), which were much better than those observed on DSA that was performed immediately after the embolization procedure. Twenty-four aneurysms (58.5%) remained stable, showing no any change, and recurrence of aneurysm was observed in 4 cases (9.7%). At the last follow-up exam, the modified Rankin scoring showed that 0 point was seen in 18 cases (43.9%), one point in 10 cases (24.4%), 2 points in 5 cases (12.2%), 3 points in 4 cases (9.8%), 4 points in 2 cases (4.85%) and 5 points in 2 cases (4.85%). The self-care rate for daily activities was 80.5%, the prognosis was good. Conclusion For the treatment of intracranial wide-necked aneurysms, SolitaireAB stent-assisted interventional embolization with spring coils is safe and effective. This technique can improve the embolization rate and reduce the procedure-related complications.

Objective:To study the anatomy of the maxillary first permanent molars. Methods:Macrography was used to observe the morphology of the mesiobuccal root,the degree of abrasion,the morphology of the floor of pulp cavity, the number and type of apical foramen.Vernier was used to measure the length indexes and the distance from the apical foramen to the tip of the root.Clearing technique was used to investigate the root canal systems. Results:26.9% of mesiobuccal root had type III apical foramen,56.25% of mesiobuccal root had two canals,7.5% teeth had three root canals. Conclusions: The maxillary first permanent molar has a high ratio of more than one root canal in mesiobuccal root(63.75%).

Objective On the basis of internet of things technology,to initially establish a management model of chronic obstructive pulmonary disease (COPD) patients in Gumei community,so as to provide experience for the comprehensive management of community COPD patients.Methods According to the characteristics of the Internet of things technology,we formulated a scheme as a technical route to manage the COPD patients.A homogenous COPD management team of doctors was established under the training of experts from the Department of Respiration of Zhongshan Hospital,Fudan University.Results We drew a COPD patient management model chart,and initially formed a qualified and homogeneous COPD management team of general practitioner.Conclusions Through the Internet of things technology management,we initially formed a set of manual quality control model in the process of data automatic transmission,and initially formed a management model of community COPD patients,based on the internet of things.

Pulpitis and periapical periodontitis is a type of bacterial infectious disease, and bacteria frequently plant in the entire root canal system during the terminal stage. Main clinical treatment strategy of the disease requires root canal therapy, a key and core procedure for the successful treatment by thoroughly removing the root canal infection. The premise and guarantee of thoroughly removing root canal infection is by determining the accurate root canal working length. However, introduction of the complexity of the apical root anatomical structure, the confusion in determining the position of apical stop, and the method to determine the root canal working length. methods of accurately determining root canal working length, especially determining the position of apical stop, has been a hot topic among endodontic specialists, frequently causing confusion among many clinicians.

Objective To study the outcome of surgical therapy of perforation of gastric cancer. Methods The clinical data of 37 cases with perforation of gastric carcinoma which underwent different surgical procedures were analyzed retrospectively. Among them,24 cases underwent partial gastrectomy,8 cases underwent radical mastectomy,4 cases had repair of perforation. 1 case received non-operative therapy. Results The preoperative diagnotic rate was 24.3%,and misdiagonsis rate was 75.7%. The perioperative mortality rate was 5.4%,including 1 case that underwent repair of perforation. The post-operative complication rate of patients undergoing palliative gastrectomy,radical gastric cancer operation and repair of perforation was 41.7%,25.0% and 75.0%,respectively,and the mean survival time was 25 months,29 months and 3.0 months,respectively.The partial gastrectomy and radical mastectomy patients had significantly better outcomes than those who underwent repair of perforation or received non-operative therapy.Conclusions For patients with perforation of gastric cancer with resectable lesions and who are in good general coaditon,a one-stage radical gastric resection or palliative subtotal gastrectomy can be performed.

Wnt signaling pathway is not only closely related to tumor invasion and metastasis,such as cancer cells migration and adhesion,extracellular matrix degradation,and angiogenesis,but also plays an important role in self-renewal,proliferation and differentiation of tumor stem cells.Progress has been made in high specific genes drug development and targeted therapy against the Wnt signaling pathway.

In the current situation,how to adapt to the new medical reform and determine its development goal has become the primary concern of the managers of No.1 Affiliated Hospital of Hebei North University.The internal and external conditions were analyzed by the method of SWOT and the advantages,disadvantages,opportunities and challenges facing the hospital were also observed.Finally,a series of countermeasures were put forward in accordance with the strategies by SWOT.
