ABSTRACT
Objective To understand the effect of standardized training teachers for fellowship training and to summarize the experience, in order to provide practical basis for standardized training of fellowship training and teachers training. Methods According to the requirements of standardized training for fellowship in Shanghai, the content of teacher training is drawn up. The training lasts for 4 days and 32 academic hours. After the training, 317 questionnaires were distributed through the form of electronic ques-tionnaire, and 301 questionnaires were recovered, with a recovery rate of 94.95％. Data statistics are in EXCEL (2016), and the data are expressed as percentage. Results Teachers participating in the training believe that fellowship training should pay most attention to the training of clinical operation skills and clin-ical thinking ability. Teachers have a high demand for training related to fellowship training policies, teach-ing ability, training quality control, teachers' professional quality and other aspects. The most popular teach-ing methods are teaching observation and discussion in small classes. 288 teachers (95.69％) thought that the teacher training was very effective or good, and 290 teachers (96.55％) thought that the teacher training would be very helpful or helpful to the future fellowship training and teaching work. Conclusion This teachers training has achieved good results. In the future, stratified and specialized training can be carried out to further improve the pertinence of teachers training. At the same time, we should strengthen the man-agement of the special training process and consolidate the special training quality. We will improve the evaluation methods and test the results.
ABSTRACT
The ability of clinical teachers plays a key role in residents standardized training. The teachers should fully understand the relevant policies and improve the awareness of resident standardized training. The construction of clinical teaching ability is the essential ability for clinical teachers and is the focus of the teacher training, which can guarantee to guide the improvement of residents' clinical thinking ability and the training of their clinical skills. Establishing teacher training system, making a suitable train-ing plan, selecting applicable training content and participating in various types of teacher training should effectively improve the comprehensive teaching ability of clinical teachers for resident standardized training.
ABSTRACT
Objective To explore the role of Hippo pathway in the pathogenesis of autosomal dominant polycystic kidney disease (ADPKD),and find potential targets for drug therapy.Methods By means of immunofluorescence staining,Western blotting,Real-time PCR,the differences of sublocalization,expression and phosphorylation level about Hippo pathway molecules in Han:SPRD (cy/+) and ADPKD patients compared with the control were observed.Knockdown Yes kinaseassociated protein (YAP),transcriptional coactivator with PDZ binding motif (TAZ) and large tumor suppressor kinase1 (LATS1) in cystic lining epithelium cell line WT9-12 were took by siRNA interference,and then their effects on cell proliferation,apoptosis and cell cycle were assessed.Results In cystic lining epithelium of Han:SPRD(cy/+),decreased expression of LATS1 and increased expression of YAP were found compared with the control,and the immunofluorescence of YAP was distributed both in cytoplasm and nucleus,while distribution and expression level of TAZ were without significant variance.Abnormal mRNA expressions of Hippo pathway components in ADPKD patients were found (P ＜ 0.05).Down-regulation of LATS1 in WT9-12 cells could prohibit phosphorylation of YAP,and prompted proliferation and cell division.Knockdown YAP in WT9-12 cells could inhibited cell proliferation by arresting cell cycle in G0/G1 phase,but down-regulating TAZ showed no significant differences in proliferation and cell cycle.Conclusions Altered Hippo signaling exists in ADPKD,and YAP activation may be one leading cause of autosomal dominant polycystic kidney disease onset.In vitro,knockdown YAP in WT9-12 cells can inhibit cell proliferation by arresting cell cycle and depressing cell division,suggesting the expression level and activity of YAP are potential targets for ADPKD treatment.
ABSTRACT
Objective To observe the influence of post-operative swallowing painwith Disposcope endoscope or Macintosh laryngoscope in patients with difficult visible glottis. Methods Thirty-six patients scheduled for elective surgery under general anesthesia whose glottis was not visible underMacintosh laryngoscope (according to Cormach-Lehane Grading of laryngoscopic view) were randomized into 2 groups (n = 18 each):Disposcope endoscope group (group D) and Macintosh laryngoscope group (group M). The rate of glottis exposure and successful intubation, swallowing pain at 30 min, 1, 3 d after extubation were observed. Results Compared with group M , the successful rate of glottis exposure and first intubation was significantly higher than thatin group D (P < 0.05). Swallowing pain VAS was higher in group M than in group D at 1d afterextubation (P < 0.05). Conclusions Compared with Macintosh laryngoscope , Disposcope endoscope in patients with difficult visible glottis could induce higher successful rate of glottis exposure and first intubation , shorter time of intubation and lower VAS of swallowing pain at 1d after extubation.
ABSTRACT
Objective To evaluate the efficacy of ultrasound-guided sacral block in the obese patients by comparing it with the traditional positioning method.Methods Sixty obese patients,aged 25-50 yr,weighing 56-80 kg,with body mass index ≥ 30 kg/m2,scheduled for elective anorectal surgery,were randomly divided into 2 groups (n =30 each) using a random number table:ultrasound-guided sacral block group (group U) and traditional positioning method group (group T).The sacral canal puncture point was located via either ultrasonic or traditional positioning method.After successful puncture,1％ lidocaine 20 ml was injected.The number of patients in whom puncture was successful at first attempt and the number of patients in whom the time for puncture ≤ 1 min were recorded.The adverse reactions were observed.The efficacy of sacral block was evaluated.Results Compared with group T,the success rate of puncture at first attempt was significantly increased (P ＜ 0.05),and no significant changes were found in the number of patients in whom the time for puncture ≤ 1 min or efffcacy of sacral block in group U (P ＞ 0.05).No adverse reactions were found in the two groups.Conclusion Ultrasound-guided sacral block can raise the success rate of puncture at first attempt and provide similar efficacy of block in the obese patients when compared with the traditional positioning method,and thus has significant clinical value.
ABSTRACT
Objective To evaluate the efficacy of Disposcope endoscope for tracheal intubation in patients with difficult glottis exposure.Methods Sixty adult patients of both sexes,aged 22-68 yr,scheduled for elective oro-tracheal intubation under general anesthesia,whose glottis was not visible under Macintosh laryngoscope (grade Ⅲ or according to Cormach-Lehane Grading of laryngoscopic view),were randomized into 2 groups (n =30 each) using a random number table:group Macintosh laryngoscope-assisted Disposcope endoscope (group DM) and group Disposcope endoscope (group D).The glottis exposure condition and time,intubation condition and time,assisted lifting mandible,laryngeal mucosa bleeding and postoperative sore throat and hoarseness were recorded.Results The success rate of intubation at second attempt achieved 100％ in the two groups.Compared with group DM,the incidence of assisted lifting mandible was decreased,and no significant changes were found in the success rate of glottis exposure,glottis exposure time,intubation time,success rate of intubation at first attempt,incidence of laryngeal mucosa bleeding,and postoperative sore throat and hoarseness in group D.Conclusion Disposcope endoscope can improve the condition for tracheal intubation significantly after lifting mandible in patients with difficult glottis exposure.
ABSTRACT
Objective To evaluate the efficacy of laryngeal mask airway (LMA) Supreme in the elderlypatients with hypertension.Methods Forty elderly patients with more than 1-year history of hypertension,aged65-75 yr,weighing 45-70 kg,with body mass index ＜ 35 kg/m2,were randomized into 2 groups (n=20 each):intratracheal intubation group (group T) and LMA Supreme group (group S).Anesthesia was induced with fenta-nyl,propofol and vecuronium.LMA Supreme was inserted in group S or intratracheal intubation was performed ingroup T for mechanical ventilation.Anesthesia was maintained with sevoflurane,propofol and vecuronium.Thesystolic blood pressure (SBP),diastolic blood pressure (DBP),heart rate (HR) and pulse oxygen saturation(SpO2) were recorded after entering the operating room (T0),at 0,1,2 and 5 min after LMA insertion or intuba-tion (T1-4),at skin incision (T5),and immediately after removal of LMA or extubation (T6).Venous blood samples were taken at T0-4,6 for determination of plasma epinephrine (AE),noradrenaline (NE) and dopamine (DA)concentrations.The insertion and removal responses,LMA insertion/intubation time and the number of inserting LMA/intubation were recorded.The lung compliance,airway peak pressure,airway sealing pressure and airway plateau pressure were detected after LMA insertion/intubation.The side effects occurred in the pharynx were recorded after removal of LMA or extubation.Results Compared with group T,the SBP,HR,insertion and removal responses,incidence of side effects and plasma AE,NE and DA concentrations were significantly decreased and LMA insertion/intubation time was significantly shortened in group S (P ＜ 0.05).Compared with the baseline value at T0,the concentration of plasma NE was significantly increased at T2 in group S,the concentration of plasma NE was significantly increased at T1-4.6 and the concentration of plasma AE and DA was significantly increased at T1.3 in group T (P ＜ 0.05).Conclusion LMA Supreme has better efficacy for airway management in the elderly patients with hypertension than intratracheal intubation,with lower insertion and removal responses and fewer side effects occurred in the pharynx.
ABSTRACT
Objective To compare the efficacy of Discoscope endoscope and GlideScope video laryngoscope for difficult glottis exposure.Methods Forty adult patients of both sexes scheduled for elective surgery under general anesthesia whose glottis was not visible at laryngoscopy (grade Ⅲ or Ⅳ according to Cormach-Lehane Grading of laryngoscopic view) were randomized into 2 groups (n =20 each):group GlideScope video laryngoscope (group G) and group Discoscope endoscope (group D).The glottis exposure time,intubating conditions,time from exposure of glottis to completion of tracheal intubation and incidence of postoperative sore throat and throat bleeding were recorded and compared between the 2 groups.Results Compared with group G,the glottis exposure time was significantly longer,the rate of backward pressure of cricoid cartilage lower,the time from exposure of glottis to completion of tracheal intubation shorter and the success rate of tracheal intubation at first attempt higher (P ＜ 0.05).There was no significant difference in the success rate of tracheal intubation at second attempt and postoperative incidence of sore throat and throat bleeding between the 2 groups(P ＞ 0.05).Conclusion DiscoScope endoscope is superior to GlideScope video laryngoscope in the management of difficult intubation in term of glottis exposure and success rate of tracheal intubation at first attempt.
ABSTRACT
Objective To analyze the causes of 652 hospitalizations in the patients with autosomal dominant polycystic kidney disease (ADPKD).Methods The medical records of all ADPKD inpatients in our hospital from January 1,1990 to December 31,2010 were collected.The differences of hospitalization causes in different age,gender and period were analyzed.Results (1)In 652 hospitalizations,the most common cause was lumbar pain (15.2％),followed by cystic bleeding (14.6％),aggravating renal failure (10.1％),dialysis-related problems (9.4％),renal transplant related issues (8.3％),renal replacement therapy for ESRD (8.0％),urinary tract infection (6.4％),end stage renal failure (5.8％),hypertension (4.1％),renal cyst volume enlargement (3.7％),finding polycystic kidney disease (2.1％),urinary lithiasis (1.8％) and others (10.4％).(2)Younger patients were admitted into hospital because of polycystic kidney bleeding and finding PKD.With the increase of patients age,hospitalization due to dialysis-related problems increased,while many middle-aged patients were hospitalized because of back pain.(3)Male patients were admitted into hospital for aggravating renal failure,ESRD,kidney transplantation-related problems and urinary lithiasis,while female patients mainly for lumbar pain,dialysis-related problems and urinary tract infection.(4)The proportion was significantly reduced with time of finding PKD,renal failure and polycystic kidney bleeding,the proportion of renal cysts increasing and aggravating renal failure increased,there was a significant increase in the proportion of patients with hypertension,while a significant decrease in the proportion of patients with uncontrolled hypertension,and the average SBP was also significantly reduced.Conclusions The highest rate of hospitalization of ADPKD patients is in 40 to 60 age group.Cause of admission varies with age and gender,and changes with the change of time.Over the past decade,the proportion of hospitalization due to renal cysts enlargement and renal failure aggravation increased significantly.The incidence of hypertension is higher than that in the first 10 years,but hypertension control rate increases compared with the previous.Prevention should focus on finding the suppression measures of renal cysts enlargement.
ABSTRACT
Objective To summarize the clinical characteristics and outcome of renal cyst infection in patients with autosomal dominant polycystic kidney disease (ADPKD). Methods Clinical data of 40 ADPKD patients with 43 episodes of renal cyst infection admitted in Shanghai Changzheng Hospital from 1st January 1991 to 31st December 2010 were retrospectively analyzed.Differences of microbiological data and treatments between 1st January 1991 to 31st December 2000 and 1st January 2001 to 31st December 2010 were compared. Results Among 473 identified patients with ADPKD and 662 episodes of hospitalization,40 patients had 43 episodes of renal cyst infection,including 8 definite and 35 likely cases.Microbiological documentation was available for 34 episodes (79.0％),Escherichia coli accounting for 82.4％ of all retrieved bacterial strains.Resistant Escherichia coli to quinolone and certain β-lactamine increased in recent decade.Clinical efficacy of initial antibiotic treatment was noted in 69.8％ of episodes. Antibiotic treatment modification was more frequently required for patients receiving initial monotherapy compared with those receiving combination therapy.In the first ten-year group,initial combination therapy and clinical efficacy were noted in 30.0％ and 60.0％ of episodes respectively,and hospital stay was (20.2±6.7) d.In the second ten-year group,initial combination therapy and clinical efficacy were noted in 61.9％ and 78.2％ of episodes respectively,and hospital stay was (16.3±3.2) d.Large infected cysts (diameter ＞5 cm) frequently required drainage. Conclusions In renal cyst infection,the source of the organisms is often a gram negative enteric organism.Empiric therapy is often initiated with two antibiotics.The drainage of large infected cysts remains the main treatment for cyst infection.
ABSTRACT
Objective To observe the influence of nocturnal prolonged hemodialysis (INHD) on patients＇ nutrition status. Methods Thirty-two maintenance hemodialysis patients received INHD (3 times per week and 7.5 hours each session) and thirty-five maintenance hemodialysis patients received conventional hemodialysis (3 times per week and 4 hours each session) as control were observed for 6 months.The nutrition status of these patients on various aspects which concluded physical measurements,laboratory tests,and dietary record at baseline(0month) and exit (6 months) were recorded. Results (1)There were no differences in age,sex,body weight,and primary diseases between two groups.(2)The body weight,triceps skinfold thickness (TSF),and hand grip strength increased at exit point,but no statistical difference compared with the control group.Mid-upper arm circumference (MAC) increased signicantly from (27.1±4.2) to (30.5±6.1) cm (P＜0.05).Compared with the control group (26.9±3.4) cm,there was a significant difference (P＜0.05).(3)Serum phosphate decreased significantly from (0.5±0.5) to (0.1±0.6) μ mol/L (P=0.001) in INHD group.(4)The nutrition status were improved in INHD group evaluated by subjective global assessment (SGA)(P=0.03).(5) Dietary intake was recorded by a 3-day food record.Dietary intake of energy,protein,lipid,calcium,potassium,and phosphate increased in INHD group.None of the differences achieved statistical significance between two groups. Conclusion As compared with conventional hemodialysis,INHD can increase the dietary intake,decrease serum phosphate level,and improve patients nutrition status.
