BACKGROUND:Over the past 10 years, scholars have proposed the tubular stomach as an alternative to the whole stomach for digestive tract reconstruction; however, its occurrence rate of postoperative complications has been controversial. OBJECTIVE:To evaluate the clinical efficacy of tubular stomach versus whole stomach for digestive tract reconstruction in the resection of esophageal carcinoma. METHODS: The randomized controled trials about tubular stomach for digestive tract reconstruction in the resection of esophageal carcinoma were searched from PubMed, OVID, CNKI, EBSCO, Science online, Wangfang, Super Star Digital Library, CMB, Baidu and Google search engines. Two searchers screened studies based on the included criteria strictly. Literature quality and bias risk were assessed according to the criteria of Cochrane Colaboration, GRADEprofiler3.6.1 software was used for evaluation of the quality grade, and Revman5.3 for data management and statistical analysis. RESULTS AND CONCLUSION:Totaly 12 randomized controled trials including 4 137 patients were enroled. Compared with the whole stomach group, in the tubular stomach group, the incidences of reflux esophagitis and thoracic stomach syndrome were significantly lower, but there was no difference in the incidences of anastomotic leakage and anastomotic stenosis between the two groups. These findings indicate that the tubular stomach as a substitute of the whole stomach for digestive tract reconstruction in the resection of esophageal carcinoma is a safe and effective. However, the literatures included are only in English and Chinese, and there is publication bias and smal sample size. Therefore, the large-sample high-quality clinical randomized controled trials are stil needed for further confirmation.

BACKGROUND: In clinical practice, the selection of dental implants with different specifications is based on the patient' s mandibular plane angle, and the long-term success rate is different in dental implants with different specifications. Therefore, it is reasonable to assume that the mandibular plane angle could affect the mandibular stress distribution of dental implants, thus affecting the success rate of dental implantation.OBJECTIVE: To perform an orthogonal experimental study on the mechanical effects of different implant specifications, mandibular plane angles and mandibular bone densities on stress distribution of the first mandibular molar implants.METHODS: A L9(33) orthogonal experiment was designed with 3 three-level factors, including mandibular plane angle (14°, 22°, 34°), implant diameter (6.6, 8.2, 9.6 mm), and mandibular bone density (types II, III, IV). Different dental implants with different combinations were implanted into an alveolar bone model, and placed onto a pressure testing machine under 500 N load. Then, strain (stress) data were collected in real-time and analyzed.RESULTS AND CONCLUSION: The optimal combination was as follows: low angle; 4.8 mm in diameter; mandibular bone with type II bone density. The relations of all the three factors were the diameter of dental implant > the mandibular plane angle > mandibular bone density. To conclude, the mandibular plane angle has some certain influences on the stability of dental implants. If the biting force is the same, dental implant bears the largest stress under the high angle,subsequently followed by the average angle and the low angle.

Objective To summarize and analyze the clinical and epidemiological characteristics of 585 cases of cutaneous sporotrichosis collected in Jilin province in the last 3 years. Methods A retrospective study was conducted on sporotrichosis cases diagnosed at the Department of Dermatology in the hospital from 2007 to 2009. Results Totally, 585 cases were included in this study. Among these patients, the male/female ratio was 1:1.35 with an average age of 40.5 years and average duration of symptoms of 6.78 months.The age at onset was mainly between 51 and 60 years (22.05%). Sporotrichosis seemed more frequently to occur in winter and spring. The majority (94.19%) of the patients were rural habitants, and 149 (25.47%) patients recalled history of trauma. Fixed form was the most common clinical presentation (56.58%), followed by lymphocutaneous form (39.66%), cutaneous disseminated form ( 1.88% ) and undefined form ( 1.88% ). The predilection sites of sporotrichosis were extremities (50.94%) and face (43.76%). The treatment of sporotrichosis included a 10% solution of potassium iodide, itraconazole and terbinafine alone or in combination. Two hundred and fifty patients were lost to follow up. Of the remaining 335 patients, 289 were cured with an average treatment duration of 2.09 months, 46 were still under follow-up or treatment. Conclusions The case load of sporotrichosis in Jilin province has remained high in recent years. The clinical and epidemic features of sporotrichosis cases in this report are similar to those in previous reports, but the proportion of middle-aged patients and atypical cases increases. Potassium iodide solution, itraconazole and terbinafine are effective and safe for the treatment of sporotrichosis.

Objective:To explore the effects of Carolina care model in standardized training of nurses.Methods:Convenience sampling was used to select 35 nurses who entered the Department of Cardiology for standardized training (referred to as training nurses) from October 2018 to March 2019 in a Class Ⅲ Grade A hospital in Changchun as control group, and 37 nurses who entered the Department of Cardiology from May to October 2019 were selected as observation group. Control group carried out routine training, and observation group implemented a training plan based on the Carolina care model. Training effects were evaluated with the Nursing Caring Characters Assessment Tool, Clinical Communication Competence Scale and Patient Satisfaction Questionnaire.Results:After training, the scores of all dimensions of the Nursing Caring Characters Assessment Tool of nurses in observation group were higher than those in control group with statistically significant differences ( P<0.05) . After training, the scores of all dimensions of the Clinical Communication Competence Scale of nurses in observation group were higher than those in control group, and the differences were statistically significant ( P<0.05) . In observation group, patients' satisfaction with training nurses was higher than that in control group with a statistically significant difference ( P<0.05) . Conclusions:The application of Carolina care model in standardized training of nurses can not only improve nurses' humanistic care and communication competence, but also improve patient satisfaction.

OBJECTIVEFinite elemental analysis of the mechanical characteristics of a first mandibular implant molar under different mandibular plane angles determines the load conditions on the implant, thereby providing guidance for clinical application.

METHODSCT data of three mandibular plane angles (low, average, high) were collected. A finite elemental combination model of a dental implant was constructed. The orthogonal experimental research was designed. Results followed data collection and analysis.

RESULTSThe optimal combination was a low angle, 4.8 mm, and type Ⅱ bone. The relations among diameter of the implant, angle of mandibular bone, and bone density were determined.

CONCLUSIONSMandibular plane angle influences the stability of a dental implant. Under constant biting force, dental implants bear the stress proportional to the angle, high angles cause high stress, average angles cause average stress, and low angles cause the least stress.
