Obstructing colorectal cancer is one of the acute abdominal diseases which are common in clinical practice.The initial symptoms of 8.0％-33.9％ patients with obstructing colorectal cancer are complete or incomplete acute colonic obstruction.Seventy percent of obstructing colorectal cancer located at the left colon.There are no standard treatment methods for obstructed left colonic carcinoma (OLCC).Previously,a staged procedure was recommended.With the improvement of the intestinal surgical techniques,one-stage resection and anastomosis including intraoperative colonic irrigation,subtotal colectomy,metal stents placement and transanal drainage tube placement were preferred by most of the surgeons.In addition,metal stents placement and transanal drainage tube placement can reduce bowel pressure,which creates the possibility for the treatment of malignant colorectal obstruction by laparoscopes.

This paper introduces the conversion of a refrigeration centrifuge into a clinical multi-use centrifuge. The method and procedure are mainly discussed.

OBJECTIVETo investigate the trans-areola approach for costicartilage harvesting in order to avoid the obvious scar resulted by traditional approach through chest incision.

METHODSFrom 2013, 7 cases who underwent rhinoplasty received costicartilage harvesting through trans-areola approach. The incision was designed along the lower interior edge of right areola. Then the dissection was performed to expose the 5th costicartilage. Then a costicartilage, 2 - 5 cm in length, was harvested. The incision was closed delicately. The suture was removed 7 days after operation.

RESULTSThe patients were followed up for 3 months to 2 years without hypertrophic scar and breast deformity. The scar was located in conceal location. The satisfactory rate was higher than that in patients with chest incision.

CONCLUSIONSThe scar resulted from trans-areola approach is comparatively conceal, compared with that at chest.

OBJECTIVE: To explore and summarize the operation method and operation stage for cochlear implant with chronic suppurative otitis media, to provide the clinical reference for cochlear implant with chronic suppurative otitis media. METHOD: The clinical data of 6 cases of cochlear implant with chronic suppurative otitis media from Jun 2006 to Mar 2009 in our hospital was analyzed retrospectively. The operation stage. surgical skill, possible risk and prognosis was analyzed and summarized. RESULT: 3 of 6 cases received single stage subtotal petrosectomy and cochlear implant. 3 of 6 cases received subtotal petrosectomy, they received staged cochlear implant 1 to 6 months later. No complications occurred, all of the cochlear implanted had good open set speech perception. CONCLUSION Staged operation was the first choice for cochlear implant with chronic suppurative otitis media. Single stage operation took potential risks, it should be done cautiously. The key points for the operation was the clearance of the pathological tissue totally, this required good surgical skill and operation instrument.

Objective To survey the shade-matching practice in Shenzhen city so as to strengthen communication between dentists and dental technicians,and to improve the successful rate of shadematching in prosthetic dentistry.Methods Questionnaire surveys were conducted in 251 dentists in some dentistry institutions of Shenzhen during the period from Aug 1st,2008 to Aug 27th,2010,including shade-guide selection,shade-matching technique and communication between dentists and technicians.Questionnaires were collected and statistically analyzed.Results From the analyzed ques tionnaires on shade-taking of 202 dentists,38.6 ％ of dentists evaluated color of restorations with Vitapan 31-Master shade guides; 17.7 ％ preferred Vitapan Classical shade guides,while 41.4 ％ used both.55.9 ％ dentists performed shade-matching in an inappropriate way with Vitapan 3D-Master shade guides.41.6 ％ of them never or rarely cornmunicated with dental technicians about color matc hing problems.Conclusions Shade guides are commonly and widely used by dentists in Shenzhen area.However,and few attentions are paid to a correct way of shade-matching and communications with dental technicians,which might be one of the main causes responsible for color mismatch.

Objective To explore the feasibility and efficiency of laparoscopic surgery for the treatment of acute biliary pancreatitis (ABP) at early stage. Methods From January 2003 to June 2006, 18 patients with ABP received laparoscopic surgeries, including laparoscopic cholecystectomy (LC) in 3, LC combined with laparoscopic common bile duct exploration (LCBDE) in 9, LC combined with opening of the pancreatic capsule for drainage in 5, and LC combined with LCBDE and opening of the pancreatic capsule for drainage in 1. Results In all the patients, the laparoscopic operations were completed successfully without conversion to open surgery. The operation time was 100-150 min with a mean of (115.3?15.2) min. The stones in the bile duct were removed completely by LCBDE in 10 patients. No subcutaneous emphysema, hemorrhage, abdominal abscess or stenosis of the bile duct occurred in this series. The 18 patients were followed up for 4-40 months (mean, 28.5 months), during which 2 patients developed pancreatic pseudocyst. One of the patients was cured by internal drainage. In the other patient, the pseudocyst was absorbed spontaneously. No recurrence of pancreatitis or common bile duct stones was found. Conclusions Laparoscopic surgery is minimally invasive and effective for the treatment of ABP at early stage.

Objective:To compare the efficacy of computed tomography(CT)and comventional X-ray plain film in assessing hip joint trauma.Methods:76 patients with hip joint trauma were studied by CT and X-ray plain film.The efficacy of CT and X-ray plain film in assessing the acetabular fracture,femoral head and neck fracture,intra-articular loose bone fragment,dislocation of hip joint,and para-articular soft tissue injuries was evaluated and compared.Results:CT was superior to X-ray plain film in demonstrating acetabular fracture,femoral head fracture and intraarticular loose bone fragment.CT was also effectively in revealing of intra-articular effusion and hemorrhage,paraarticular soft swelling.Conclusion:CT was a necessary way to evaluated hip joint trauma,and was more effective than X-ray plain film in diagnosis of hip joint trauma.

The application of medical network education system has created favorable conditions for the network education in our hospital. This paper describes the system and resource database construction, educational application and some problems confronted. Construction improvement and widely application of the system are also thoroughly discussed.

Objective:To investigate the immediate bond strength and surface structure of resin and the tooth enamel which treated by cold plasma.Methods:In the study,40 bovine incisors were divided into two equal parts.In this sense,all enamel adhesive samples were prepared and then randomly divided into 4 groups(n =20).group 1:acid +single bond 2 +resin composite(control group);group 2:beyond bleaching+acid+single bond 2+resin composite;group 3:treated by cold plasma for 5 minutes+acid+single bond 2+resin composite;group 4:treated by cold plasma for 5 minutes+single bond 2+resin composite.Single bond 2 bonding system and Filtek Z250 resin were used in this experiment.The shear bond strength was tested by universal testing machine.The surface of the enamel in different processes was observed by scanning electron microscope (SEM).Statistical analyses by the single factor analysis of variance and multiple pairwise comparisons were performed with SPSS 1 7 .0 .Results:The shear bond strength of group 4 (8.60 MPa)was significantly lower than that of the other three groups (P<0.05). The shear bond strength of group 2 (1 7.89 MPa)was higher than that of group 4,but lower than group 1 and group 3 (P<0.05).There was no significant difference between group 1 (34.82 MPa)and group 3 (34.69 MPa).Scanning electron microscope indicated that the enamel treated by cold plasma had slight molten form,which was different from etched enamel surface.The fractured surface of group 3 was mix fracture,which was similar to the control group (group 1 ).Conclusion:Compared with the conven-tional clinic bleaching,immediate bond strength of resin-enamel that treated by cold plasma has not been affected.
