This paper summarizes the clinical experience in applying jiao （角） medicine to treat diabetes mellitus from the perspective of qi， blood， and fluids. It is believed that impaired spleen transportation and transformation is the key pathomechanism of diabetes， leading to metabolic disturbances in qi， blood， and fluids， and resulting in a sequential pathological progression of "qi → thick fluids → thin fluids → blood". At the qi level， the disease is mainly characterized by spleen qi deficiency and stagnation， and is commonly treated with Hongshen （Panax Ginseng）， Huangqi （Astragalus Mongholicus）， and Baizhu （Atractylodes Macrocephala） to tonify the spleen and regulate qi. At the thick fluids level， the condition manifests as abdominal distension， internal heat， and turbid pathogens， requiring Zexie （Alisma Orientale）， Huanglian （Coptis Chinensis）， and Dahuang （Rheum Palmatum） to clear the spleen and drain turbidity. At the thin fluids level， with qi and yin deficiency and predominant yin damage， Gegen （Pueraria Lobata）， Wuweizi （Schisandra Chinensis）， and Maidong （Ophiopogon Japonicus） are used to nourish yin and generate fluids. At the blood level， where vascular damage is predominant， Shuizhifen （Whitmania Pigra Powder）， Danshen （Salvia Miltiorrhiza）， and Sanqifen （Panax Notoginseng Powder） are applied to activate blood circulation， resolve stasis， and unblock the channels. Clinicians may flexibly select appropriate jiao medicine based on the specific pathological layer affected in each patient.

Objective In order to summarize the implementation status and effectiveness of entrusted management projects in municipal hospitals of Beijing,the project aims to better promote the extension of high-quality urban re-sources to county-level hospitals.Methods Through survey questionnaires and focus group interviews,the survey questionnaire includes the size of the hospital,the number of surgeries,Case Mix Index,annual average number of new technologies and projects,personnel training entrusted,and interviews with 50 heads of municipal hospi-tals,district hospitals,and district level government relevant departments.Results Measures for medical homogeni-zation,talent cultivation,management,and cultural homogenization were sorted out.In terms of hospital scale,level evaluation,medical service capabilities,and the proportion of master's degree and above personnel in the managed hospitals,an upward trend was observed.Conclusion The medical cooperation project entrusted by Beijing Municipal Hospitals promotes the integration of regional medical services,and provides reference for the expansion and sinking of high-quality medical resources from the management mechanism,operation mechanism and key measures.

The management of chronic diseases at the county-level faces the problems of low degree of standardized manage-ment,weak management capacity of chronic diseases at the grassroots level,and shedding management of chronic disease patients.The"county-level chronic disease management center"proposed in the"Thousand Counties Project"can promote the county-town-ship-village medical institutions to jointly provide integrated and continuous chronic disease management services for county resi-dents.The study conducted in-depth interviews and analyses on the construction of the centers in 10 county(district)hospitals.Con-clusion:Firstly,the construction of the centers is in its infancy,and the support of government investment,performance incen-tives,and informatization construction is insufficient;secondly,the service content of the current centers is not clear enough,and the collaborative management model of chronic diseases in counties and villages is not stable.Enlightenment:The county-level med-ical community has built an effective path for the centers and the construction of chronic disease management centers needs to be fur-ther strengthened in terms of finance,medical insurance,interest mechanism,informatization construction and awareness of chronic diseases.

Objective To analyze the concentration and exposure of vancomycin in children with gram-positive coccal infection,and the corresponding clinical efficacy and safety to support rational use of vancomycin in children.Methods We prospectively collected the clinical and laboratory data of 87 children with gram-positive coccal infection in the Children's Hospital of Fudan University from January 2012 to March 2021.Therapeutic drug monitoring(TDM)was conducted for vancomycin simultaneously,to acquire the data of serum through concentration(Cmin),peak concentration(Cmax),the area under the drug concentration-time curve in a 24-h interval(AUC0-24h)and the ratio ofAUC0-24h to the minimum inhibitory concentration(AUC0-24h/MIC).Results The median(P25,P75)age of the children enrolled in this study was 3.60(1.20,20.00)months.The median dose of vancomycin was 39.23(30.00,46.51)mg/kg.The median serum Cmin was 3.30(1.50,7.10)mg/L.Cmin achieved the target(5-15 mg/L)in 23 cases(26.4％).The median AUC0-24h was 213(174,293)mg·h/L and the median AUC0-24h/MIC was 221(128,349).Adaily dose of above 60 mg/kg in children could achieve the median value of AUC0-24h and AUC0-24h/MIC greater than 400,and the corresponding median age was 28.50(6.85,36.00)months.Multivariate logistic analysis showed a good correlation between Cmin and AUC0-24h(P=0.002).At the end of treatment,the clinical efficacy rate was 85.1％(74/87)and the bacterial eradication rate was 95.4％(83/87).No renal injury occurred during the treatment.Conclusions In this study,the median daily dosage,Cmin and A UC0-24h/MIC of vancomycin were below the recommended range at home and abroad.However,good clinical and microbiological efficacy were achieved in children at low vancomycin exposure.The probability of target attainment(PTA)for A UC0-24h and AUC0-24h/MIC ≥400 increased when the daily dose of vancomycin was＞60 mg/kg(corresponding to the median age of 28.50 months)or Cmin ≥ 5 mg/L.

Objective To investigate the attitudes and influencing factors of transplantation-related populations towards kidney xenotransplantation. Methods From June 2022 to January 2023, stratified random sampling was performed from patients awaiting kidney transplantation, patients after kidney transplantation, patients' relatives and medical students. Four hundred subjects were collected from each population and 1600 subjects were investigated using a self-designed questionnaire. Baseline data of the respondents, their attitudes towards kidney xenotransplantation and the reasons of rejecting kidney xenotransplantation were analyzed. The influencing factors of attitudes towards kidney xenotransplantation were also identified. Results A total of 1 493 valid questionnaires were collected, and the questionnaire retrieval rate was 93.31%. About 93.10% of the respondents accepted allogeneic kidney transplantation, and 66.78% had heard of kidney xenotransplantation. Seven hundred and ninety-five respondents suggested that they could accept kidney xenotransplantation "when kidney xenotransplantation and allogeneic kidney transplantation yielded the same results and risks". Six hundred and ninety-eight respondents indicated that they were "unable" or "uncertain" whether they could accept kidney xenotransplantation (χ²=16.409，P=0.001). Among these 698 respondents, the proportion of them who were willing to accept kidney xenotransplantation when they did not meet the conditions of allogeneic kidney transplantation was 10.9%. About 35.8% of respondents were willing to accept kidney xenotransplantation if it yielded less risk and better prognosis compared with allogeneic kidney transplantation. If the time of awaiting kidney xenotransplantation was shorter than that of allogeneic kidney transplantation, 21.2% were willing to accept kidney xenotransplantation. If the cost of kidney xenotransplantation was less than that of allogeneic kidney transplantation, 24.5% of them were willing to accept kidney xenotransplantation. The main reasons of rejecting kidney xenotransplantation included surgical risk and other unknown risks. Multivariate analysis showed that respondents residing in cities and towns for a long period of time, those who accept allogeneic kidney transplantation and those who have heard of kidney xenotransplantation showed more positive attitudes towards kidney xenotransplantation. Conclusions Different transplantation-related populations have different attitudes towards kidney xenotransplantation, and the overall attitudes are positive. Active promotion of kidney xenotransplantation research and carrying out relevant popular science education contribute to improving public attitudes towards the acceptance of kidney xenotransplantation.

Objective To evaluate the changing trend of serum thyrotropin (TSH) levels for hemithyroidectomy patients,and to discuss the necessity and strategy of TSH suppression for low-risk differentiated thyroid carcinoma(DTC). Methods One hundred and twenty-seven patients with benign thyroid nodules undergoing hemithyroidectomy between January 2013 and June 2014 were retrospectively studied. Serum thyroid hormones levels FT3,FT4,TSH,thyroid peroxidase antibody(TPOAb),and thyroglobulin antibody(TGAb)were detected at 1 month after surgery for all patients and at 3 month for 54 patients. Results (1)Mean TSH level at 1 month after surgery was significantly higher than preoperative TSH level(2.45 mIU/L vs 2.20 mIU/L,n=127,P<0.01). The mean TSH level at 3 month after operation was significantly higher than preoperative ones(2.46 mIU/L vs 2.35 mIU/L,n=54, P<0.05). (2)TSH<2. 0 mIU/L was found in 52 patients(40. 9%) and TSH>4. 94 mIU/L in 18 patients (14.17%) at 1 month after operation. TSH<2.0 mIU/L was found in 28 patients(51.85%)and TSH>4.94 mIU/L in 8 patients(14.81%) at 3 month after operation. (3)A preoperative TSH≥2.0 mIU/L and the coexistence of Hashimoto's thyroiditis were found to be independent risk factors for the TSH levels higher than 2.0 mIU/L. Among the patients with TSH≥2. 0 mIU/L at 1 month, 13 exhibited spontaneous recovery at 3 month, coexistence of Hashimoto's thyroiditis was related to this phenomenon. Among the patients with TSH<2.0 mIU/L at 1 month,TSH levels were elevated over 2. 0 mIU/L in 7 patients by 3 month comparing to that by 1 month. Coexistence of Hashimoto's thyroiditis was independent risk factor for the TSH elevation. Conclusion TSH suppression may still be performed to patients with low risk DTC after operation especially to whom the preoperative TSH≥2.0 mIU/L and the coexistence of Hashimoto's thyroiditis. Suppression therapy should be carefully considered with close follow-up.

OBJECTIVETo investigate the predictive value of pediatrics end-stage liver disease (PELD) or the model for end-stage liver disease (MELD) in the prognosis of pediatric acute liver failure (PALF) treated with artificial liver support system (ALSS).

METHODThe clinical data of 47 children with acute liver failure seen from August 2008 to July 2013 treated in Children's Hospital, Fudan University were analyzed. Thirty children were treated with ALSS in addition to conventional comprehensive medical treatment (ALSS group). Seventeen children were treated with only conventional comprehensive medical treatment (control group). The main biochemical parameters and coagulation function parameters before and after treatment were compared in the ALSS group and the mortality rates were compared between the two groups. The patients were graded by PELD or MELD when they were hospitalized and the relationship of PELD or MELD scores and mortalities of child patients with the receiver operating characteristic curve (ROC) were analyzed.

RESULTThere were significant differences in total bilirubin (TB) ((302 ± 208) vs. (161 ± 129) µmol/L); alanine aminotransferase (ALT) ((161 ± 225) vs. (761 ± 834) U/L); aspartate aminotransferase ( AST) (66 (35, 123 ) vs. 447 (184, 1,129 ) U/L) ; international normalized ratio (INR) ((2.6 ± 1.6) vs. (5.1 ± 4.0)); prothrombin time activity percentage (PTA) ((42 ± 25)% vs. (22 ± 13)%); albumin( ALB) ((35 ± 5) vs. (33 ± 6) g/L) in the ALSS group after treatment. Through the ROC curve analysis, the best PELD/MELD threshold was 25 to predict the patients survival after ALSS therapy, with a sensitivity of 92. 3% , and a specificity of 94.1% at the cutoff point. The area under the ROC curve was 0. 912. The mortality of patients with PELD or MELD score below 25 in the ALSS group (1/13) was lower than the control group (3/4) (P = 0.022), and the mortality of patients with PELD or MELD score over 25 (16/17) was higher than that of the control group (10/13) (P = 0.290).

CONCLUSIONPELD or MELD score is a valid index in prognostic evaluation of ALSS therapy, which may provide an evidence for the therapeutic strategies of PALF. Patients with PELD or MELD score below 25 treated with ALSS obtained more benefit.
