Taking Kunming Medical University as an example, we explore the mechanism for the separation and coordination of supervision, management, and evaluation, establish and implement a course quality rating system, and strengthen the course quality evaluation. The course quality rating system mainly consists of merit evaluation for courses of grades A and B and admittance evaluation for courses of grades C and D. Through the course quality rating, courses are diagnosed and compared, with the aim to improve course connotation construction (labeling, setting an example, promoting excellent courses, and removing inferior courses), achieve "good pay for good courses", encourage the faculty to strengthen curriculum quality, and measure ourselves with our own ruler. We discussed the problems about the difference in evaluation indicators, the professionality of evaluators, and the incentive effect of evaluation results, and also proposed strategies for improving course quality rating in medical colleges from the perspectives of deepening the content of evaluation indices, ensuring the effectiveness after evaluation, and ascertaining the main body of course construction in daily work.

Objective To evaluate the early imaging characteristics and function of bladder wall reconstruction neourethra(BWN)after robot-assisted laparoscopic prostatectomy(RALP)for prostate cancer with magnetic resonance imaging(MRI)and voiding cystourethrography(VCUG).Methods A total of 36 patients who underwent RALP using BWN technique at Taizhou People's Hospital during Mar.2021 and Jun.2023 were enrolled.Postoperative MRI was used to measure the length,wall thickness,and lumen shape of the new urethra.The morphology of the new urethra in 19 patients was observed under VCUG during the storage phase,voiding phase,and interrupted voiding phase.Results The patients'median age was 73.00 years(range:68.00 to 76.25),the prostate volume was(45.01±7.18)cm3,and the median total prostate-specific antigen(tPSA)level was 10.77 ng/mL(range:7.30 to 14.86).Two patients were classified as T1 stage,25 as T2,and 9 as T3.Gleason scores were ≤6 in 7 patients and ≥8 in 8 patients.Risk classification was low risk in 2 patients and high risk in 8 patients.Postoperatively,urinary control rates at 1,3,and 6 months were 91.67％,97.22％,and 100％,respectively.MRI revealed a median new urethra length of 15.13 mm(range:12.71 to 20.26)and a median wall thickness of 6.84 mm(range:6.18 to 8.20).The urethral lumen had a complete muscular layer and mucosal layer,which appeared petal-like.In patients with urinary incontinence,residual urine was visible in the new urethra and at the anastomosis site.Of the 19 patients who underwent VCUG,16 could close the new urethra during the storage and interrupted voiding phases,and open it during the voiding phase;3 could not close it well during the storage and interrupted voiding phases.Conclusion MRI and VCUG clearly demonstrate that the BWN technique can successfully create a new urethra with good functionality,which helps improve urinary control after RALP for prostate cancer.

Objective To summarize clinical experience of transabdominal pericardial anastomosis of suprahepatic vena cava of the donor and right atrium of the recipient in liver transplantation for Budd-Chiari syndrome (BCS) complicated with liver cancer. Methods Clinical data of a BCS patient complicated with liver cancer undergoing transabdominal pericardial anastomosis of suprahepatic vena cava and right atrium in liver transplantation were retrospectively analyzed. Results The hepatic vein and suprahepatic vena cava were partially occluded in the patient. Liver transplantation was completed by transabdominal pericardial anastomosis of suprahepatic vena cava and right atrium with beating-heart. In addition, due to pathological changes of the recipient's hepatic artery, splenic artery of the recipient was cut off, distal ligation was performed, and the proximal end was reversed and anastomosed with the common hepatic artery of the donor liver, and the reconstruction of hepatic artery was completed. The surgery was successfully performed. At approximately postoperative 1 week, the function of the liver allograft was gradually restored to normal, and no major complications occurred. The patient was discharged at postoperative 25 d. No signs of BCS recurrence was reported after 8-month follow-up. Conclusions It is safe and feasible to treat BCS by liver transplantation with transabdominal pericardial anastomosis of suprahepatic vena cava and right atrium. BCS patients complicated with liver cancer obtain favorable prognosis.

Objective To evaluate the effect of different techniques of hepatic artery reconstruction on postoperative hepatic artery complications and clinical prognosis in liver transplantation. Methods Clinical data of 140 liver transplant recipients were retrospectively analyzed. All recipients were divided into the conventional hepatic artery reconstruction group (n=123) and special hepatic artery reconstruction group (n=17) according to hepatic artery reconstruction methods. Intraoperative and postoperative clinical indexes, the incidence of postoperative hepatic artery complications and survival rate were compared between two groups. Results The alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels at postoperative 1 d, total bilirubin (TB) at postoperative 7 d and prothrombin time international normalized ratio (PT-INR) at postoperative 30 d in special hepatic artery reconstruction group were higher than those in conventional hepatic artery reconstruction group, and the differences were statistically significant (all P < 0.05). There were no significant differences in the operation time, anhepatic phase, intraoperative blood loss, intraoperative transfusion volume of red blood cells, cold or warm ischemia time, the length of intensive care unit (ICU) stay, the length of hospital stay and postoperative blood flow of liver allograft between two groups (all P > 0.05). In the conventional hepatic artery reconstruction group, 5 recipients developed hepatic artery complications, whereas no hepatic artery complications occurred in the special hepatic artery reconstruction group, with no significant difference between two groups (P > 0.05). In the special hepatic artery reconstruction group, the 1-, 3- and 5-year cumulative survival rates were equally 82.4%, compared with 85.0%, 78.9% and 75.6% in the conventional hepatic artery reconstruction group, respectively. There was no significant difference between two groups (all P > 0.05). Conclusions When hepatic artery variations and (or) lesions are detected in donors and recipients, use of special hepatic artery reconstruction may effectively restore the hepatic arterial blood flow of liver allograft after liver transplantation, and will not affect the incidence of hepatic artery complications and survival rate of the recipients following liver transplantation.

Objective:To investigate the efficacy and safety of laparoscopic partial nephrectomy in the treatment of renal tumors with renal score of 10.Methods:From February 2016 to March 2021, 23 patients who underwent laparoscopic partial nephrectomy in Peking University Third Hospital with renal tumors of R. E.N.A.L. score of 10 was studied retrospectively, including 16 cases of male and 7 cases of female, with 11 cases on the right side and 12 cases on the left side. The patients’ age was (55.0±16.4) years, and BMI was (25.4±3.6) kg/m 2. The maximum diameter of the tumor was (3.5±1.4)cm. Laparoscopic partial nephrectomy was performed after complete examination. The observation indexes included operation time, blocking time, complications, postoperative hospital stay and the trifecta (negative surgical margin, blocking time ≤25 minutes, and no perioperative complications). Results:All operations were successfully completed, only 4 cases were converted to open surgery. The median operation time was 153 min(99-346 min). The median blocking time was 27 min(14-60min). The median postoperative hospital stay was 6 d(4-11 d). Postoperative complications occurred in 7 cases(fever in 5 cases, intestinal obstruction in 1 case, postoperative blood transfusion and leg intermuscular venous thrombosis in 1 case). 9 cases (39.1%) achieved the trifecta. 19 cases who completed by laparoscopy, their operation time was 151 min(99-303 min), blocking time was 28 min(18-60 min), postoperative hospital stay was 6 d(4-11 d), fever occurred in 4 cases, and 6 cases achieved the trifecta (31.6%). The follow-up time was 3-62 months, with a median of 32 months, and there was no recurrence or metastasis.Conclusions:Laparoscopic partial nephrectomy is safe and effective in the treatment of renal tumors with renal score of 10.Although the tumor is highly complex, it also achieves the purpose of preserving nephron to the greatest extent. If technical conditions permit, laparoscopic partial nephrectomy could be considered for the treatment of highly complex renal tumors.

Objective:To investigate the efficacy and safety of dexmedetomidine in noninvasive continuous positive airway pressure(NCPAP)for acute respiratory failure in children.Methods:Clinical data of children with acute respiratory failure who underwent NCPAP from January 2018 to March 2020 in PICU of Hunan Children′s Hospital were prospectively collected.They were randomly divided into dexmedetomidine group(group D)and midazolam group(group M), with a total of 100 children.We compared the sedation depth of the two groups at 7 time points after sedation at 0.5 h(t1), 1 h(t2), 2 h(t3), 6 h(t4), 12 h(t5), 24 h(t6), and 48 h(t7), time to reach proper sedation, NCPAP time, NCPAP failure rate, oxygenation index(P/F value)before sedation(T0)and 1h(T1), 24h(T2), and 48h(T3)after sedation, and the main vital signs and adverse reactions before sedation(T0)and 1h(T1), 24h(T2), 48h(T3)after sedation.Results:(1)The proportion of proper sedation at T4, T5, T6 and T7 after sedation in group D was higher than that in group M[98%(49/50)vs.84%(42/50), 94%(47/50)vs.90%(45/50), 96%(48/50)vs.88%(44/50), 90%(45/50)vs.88%(44/50), χ2=6.538, 8.043, 8.174, 7.678, all P<0.05]. Time to reach proper sedation in group D was shorter[(58.6±7.9)s vs.(66.7±9.3)s, t=4.682, P<0.01]. (2)The treatment time and failure rate of NCPAP in group D were lower than those in group M[(134.9±25.5)h vs.(147.8±24.3)h, 10%(5/50)vs.28%(14/50), all P<0.05]. P/F after NCPAP treatment in the two groups was improved as compared with that before treatment(all P<0.01), and the improvement was more significant in group D than in group M at T2 and T3 after sedation[(199.3±26.1)vs.(188.5±24.2)mmHg, (212.2±25.4)mmHg vs.(200.8±24.8)mmHg, t=2.132, 2.278, all P<0.05]. (3)There were no significant differences in heart rate(HR), mean arterial pressure(MAP), and respiratory rate(RR)before sedation between the two groups(all P>0.05). HR and RR after sedation in both groups decreased as compared with those before sedation( P<0.01). HR at T1, T2, and T3 after sedation in group D decreased more significantly than that in group M[(116.3±17.6)bpm vs.(124.8±14.1)bpm, (110.2±18.4)bpm vs.(121.9±15.2)bpm, (108.5±18.7)bpm vs.(117.6±12.8)bpm, t=0.479, -3.474, -2.840, all P<0.05]. There was no significant difference in RR after sedation between the two groups( t=1.872, 1.632, 1.675, all P>0.05). MAP at T1 in group D decreased as compared with T0( P<0.01). MAP at T1 in group D was lower than that in group M[(65.5±5.1)mmHg vs.(68.0±5.7)mmHg, t=-2.297, P=0.024]. (4)There was no significant difference in the incidence of total adverse reactions between the two groups[20%(10/50)vs.14%(7/50), P=0.595]. The incidence of bradycardia was higher in group D than in group M[16%(8/50)vs.2%(1/50), P=0.031]. Conclusion:The incidence of adverse reactions of dexmedetomidine and midazolam in the sedation of NCPAP in children with acute respiratory failure is similar, but the sedative effect of dexmedetomidine is better than that of midazolam in the improvement of pulmonary oxygenation.

Objective:To explore the application value of heparin-binding protein (HBP) in the early diagnosis and assessment of severe adenovirus pneumonia.Methods:A total of 90 children diagnosed with adenovirus pneumonia admitted in the Department 1 of Emergency and Pediatric Intensive Care Unit 1 in Hunan Children′s Hospital from January 2019 to March 2020 were recruited.HBP levels in children with adenovirus pneumonia were detected.The correlation between HBP with white blood cell count (WBC), neutrophil ratio (N), C-reactive protein (CRP), interleukin-6(IL-6) and erythrocyte sedimentation rate (ESR) were examined.Receiver operating characteristic(ROC) curve analysis was conducted to explore the value of HBP in the early diagnosis and assessment of severe adenovirus pneumonia.Children with adenovirus pneumonia were divided into severe adenovirus pneumonia group (severe group) and non-severe adenovirus pneumonia group (non-severe group) according to their severity.Those in the severe group were further divided into bronchiolitis obliterans(BO) group and non-BO group according to the occurrence of BO.Results:(1) The HBP level in children with adenovirus pneumonia was (49.47±34.19) μg/L, which was significantly higher in the severe group than that of non-severe group[(82.88±44.02) μg/L vs.(35.15±13.08) μg/L, t=15.349, P<0.05]. Children in the severe group were significantly younger, and they had a significantly longer length of stay, lower Pediatric Critical Illness Scores (PCIS), and higher inflammatory markers like HBP, WBC, N, CRP, IL-6, and ESR compared with those of the non-severe group (all P<0.05). No significant difference in the procalcitonin (PCT) level was detected between groups.(2) The HBP was positively correlated with inflammatory markers like WBC ( r=0.38, P<0.05), N ( r=0.26, P<0.05), CRP ( r=0.47, P<0.05), IL-6 ( r=0.76, P<0.05), and ESR ( r=0.35, P<0.05). However, HBP did not have a significant correlation with PCT ( r=0.097, P>0.05). (3) In the severe group, the HBP level of the children with invasive mechanical ventilation, oxygenation index(P/F index)≤ 200 mmHg (1 mmHg=0.133 kPa) and BO was significantly higher than that of the non-invasive mechanical ventilation, P/F index> 200 mmHg and non-BO (all P<0.05). (4) The area under the ROC curve of HBP, WBC, N, CRP, ESR and IL-6 in predicting the severity of adenovirus pneumonia were 0.915, 0.748, 0.770, 0.740, 0.820 and 0.798, respectively.When the cut-off value of HBP was 45 μg/L, the sensitivity and specificity of HBP were 81.48% and 85.71%, respectively. Conclusions:As an inflammatory mediator, HBP is involved in the inflammatory response of the body.It may be a useful new marker for the early diagnosis of severe adenovirus infection, which also has a certain value in the evaluation of the severity and prognosis of the disease.The findings provide a basis for early clinical intervention and treatment of adenovirus infection in children.

Objective:To investigate the relationship between childhood psychological abuse and dark triad with suicide ideation, and to provide references for suicide prevention in college students.Methods:A total of 2 995 college students from 6 universities including Guangxi, Sichuan, Henan, Guizhou and Chongqing were enrolled, and were investigated with the child psychological maltreatment scale (CPMS), dirty dozen(DD), and suicide ideation questionnaire.SPSS 26.0 software was used for correlation analysis and macro program-PROCESS was used to analyze the mediating effect.Results:The prevalence of childhood psychological maltreatment among college students was 29.32%, which in male students and students with left-behind experience (33.38%, 34.60%) were higher than that in female students and students without left-behind experience (25.65%, 25.98%)(χ 2=21.53, 25.47, both P<0.01) respectively.There was positive correlation between childhood psychological maltreatment, dark triad and suicidal ideation( r=0.32-0.41, all P<0.001). Dark triad had a partial mediating effect between childhood psychological maltreatment and suicidal ideation(effect size=0.08, 95% CI=0.06-0.10). An analysis of multiple mediating effects on the three dimensions of dark triad found that Machiavellianism and psychopathy had significant mediating effects between childhood psychological maltreatment and suicidal ideation(effect size=0.05, 95% CI=0.02-0.07; effect size=0.07, 95% CI=0.04-0.10), while narcissism had no significant mediating effect(effect size=-0.01, 95% CI=-0.01-0.01). Conclusion:Childhood psychological maltreatment can not only directly affect the suicide ideation of college students, but also further affect the suicide ideation through dark triad.

From September to November 2019, three patients with Hornet stings were admitted to hospital with acute anaphylaxis and various degrees of organ dysfunction. After hemoperfusion combined with continuous hemodialysis and hormone pulse therapy, 1 patient was successfully treated and 2 patients were not cured. Bee Stings can cause systemic allergic reactions and toxic reactions. In severe cases, acute anaphylaxis, rhabdomyolysis, intravascular hemolysis, abnormal coagulation, and acute liver and kidney injury may occur, myocardial damage and other multi-organ function damage or even failure, is a clinical acute and critical illness, mortality is higher. Through the analysis of the diagnosis and treatment process of these 3 cases, the experience is summarized: the Bee sting should be treated as soon as possible, the early prevention and treatment of multiple organ dysfunction, the choice of accurate blood purification and comprehensive treatment, can effectively improve the prognosis, increase the success rate of treatment.
