Objective To investigate the labeling of dialysis-related information in the instructions of drugs for systemic use in patients with end-stage renal disease undergoing hemodialysis,and to provide reference for further standardization and im-provement of drug instructions.Methods Collected the information on pharmacokinetics and drug dose adjustment in hemodi-alysis patients with end-stage renal disease from the instructions of chemicals and biologics used systemically in XuanWu hospital's formulary from January to March 2023.Classified and compared the labeling rates of the corresponding information of the originally developed drugs and generic drugs,imported drugs and domestic drugs;Drugs eliminated by non-renal route,or with mo-lecular weight≥5 000,or binding rate of plasma protein ≥ 60％,or drug distribution volume＞360L were classified as"non-dialysis group",and other drugs were classified as"dialysis group",compared the labeling rate of corresponding information of drugs in"dialysis group"and"non-dialysis group";and compared the labeling rate and content with relevant information in Lexicomp and Micromedex.Results Among the 930 drug instructions,the labeling rates of drug dialysis clearance,drug adjustment,and ex-plicit drug adjustment plan were 16.67％,25.16％,and 24.52％.There was no significant difference in the labeling rate of dialysis-related information between original and generic drugs,and imported and domestic drugs.There was a significant difference in the labeling rate of dialysis-related information between the"dialyzable group"and the"non-dialyzable group"(P＜0.01).The differ-ence in the labeling rate of dialysis related information between the investigated drug instructions and the corresponding drugs in Lexicomp or Micromedex was statistically significant(P＜0.01).Conclusion Attention should be paid to the lack of informa-tion and unclear labeling of hemodialysis patients with end-stage renal disease in the drug instructions by relevant departments.

Objective:To compare the differences of long-term survival rates between hemodialysis (HD) and peritoneal dialysis (PD) in the oldest old end-stage renal disease (ESRD) patients, and analyze the influencing factors of mortality.Methods:It was a retrospective cohort study. The clinical data from the oldest old patients (≥80 years old) who underwent HD or PD for the first time and maintained dialysis treatment for ≥3 months in the Zhejiang Dialysis Registration System from January 1, 2008 to December 31, 2021 were collected. The follow-up endpoint was until the patients' death or December 31, 2022. The propensity score matching method was used to match groups. Kaplan-Meier method and log-rank test were used to compare the differences of long-term survival rates between the two groups. Cox regression analysis was used to analyze the risk factors of mortality.Results:A total of 5 880 the oldest old dialysis patients were included in this study, with 5 363 patients in the initial HD group and 517 patients in the initial PD group. After matching, there were 517 patients in the HD group and 517 patients in the PD group. The median survival time of HD group before matching was 39.9 months, with 1-year, 3-year, and 5-year survival rates of 85.4%, 54.9%, and 30.0%, respectively. The median survival time of PD group was 32.9 months, with 1-year, 3-year, and 5-year survival rates of 82.5%, 47.1%, and 22.3%, respectively. After matching, the median survival time of HD group was 40.3 months, and the 1-year, 3-year, and 5-year survival rates were 86.1%, 57.8%, and 29.1%, respectively. The survival rate of PD group remained unchanged. The difference of 1-year survival rate between the two groups was not statistically significant, but the 2-year, 3-year, 4-year, 5-year, and overall survival rates in HD group were higher than those in PD group (Log‐rank test, χ2=4.897, P=0.027; χ2=9.693, P=0.002; χ2=10.194, P=0.001; χ2=7.868, P=0.005; χ2=12.510, P<0.001). Multivariate Cox regression analysis showed that HD (HD/PD, HR=0.794, 95% CI 0.669-0.943, P=0.009), increasing age ( HR=1.069, 95% CI 1.038-1.110, P<0.001), comorbidity with chronic obstructive pulmonary disease ( HR=1.510, 95% CI 1.065-2.139, P=0.021) and serum albumin <35 g/L ( HR=1.393, 95% CI 1.165-1.665, P<0.001) were independent correlated factors of mortality. Conclusions:There is no significant difference in the 1-year survival rate between HD and PD groups. The survival rate for more than 1 year in HD patients is higher than that in PD patients. HD is an independent protective factor of survival, and increasing age, comorbidities of chronic obstructive pulmonary disease, and serum albumin <35 g/L are independent risk factors affecting the survival in the oldest old dialysis patients.

The silent lung that occurs during the perioperative period is characterized by rapid onset,rapid progression,and high mortality.This article reports a case of a 62-year-old patient with a left lower lung nodule who underwent lower lung segmentectomy under thoracoscopy and was assisted with tracheal intubation using rocuronium.21 minutes after the first administration,the patient presented with increased airway pressure,difficult ventilation,a"steel lung"feel,and symptoms similar to silent lung.Subsequently,80 mg of methylprednisolone and 50 μg of epinephrine(in divided doses)were injected intravenously,but no relief was observed,and the blood oxygen saturation decreased to 38％.In this case,after giving another 1 mg of epinephrine,the airway pressure gradually decreased to 33 cmH2O,and the blood oxygen saturation gradually increased.Considering that airway spasm might be caused by multiple intubation stimulations,additional rocuronium bromide was added to allow for reintubation.However,the patient again experienced increased airway pressure and difficulty in ventilation prior to intubation.The clinical pharmacist conducted a correlation evaluation of this adverse event and considered the result as possible.The mechanism,rescue and prevention of silent lung induced by rocuronium was also discussed in the case report.A thorough anesthesia assessment should be conducted prior to surgery,and an appropriate anesthesia induction plan should be formulated.Once an adverse event occurs,it should be promptly identified and treated.

BACKGROUND:Talus cartilage injury is a common motor system disease.This type of injury will affect the patient's daily life and work ability,and may worsen the condition if left untreated.Surgical treatment is commonly used,but the selection of surgical methods and the evaluation of medium-and long-term follow-up results have always been difficult clinical problems. OBJECTIVE:To explore the influence of T1ρ technique on the range of quantitative evaluation of talus osteochondral injury on the choice of surgical method and the results of medium-and long-term follow-up. METHODS:A total of 154 patients with osteochondral injury of talus admitted to The Second Hospital of Tangshan from January 2019 to August 2022 were retrospectively selected as the study subjects.The lesion site of talus was examined by MRI before operation,and the T1ρ and T2 values of different types were compared.Different surgical methods were selected according to the different T1ρ values.Group A(n=73)was treated with microfracture surgery with T1ρ<45 ms;group B(n=81)was treated with autogenous bone and cartilage transplantation with T1ρ≥45 ms.The general clinical characteristics and curative effects of patients under different surgical methods were compared;the important factors of postoperative recurrence were analyzed by multivariate Logistic regression,and the relationship between T1ρ value and postoperative recurrence was analyzed by restricted cubic spline graph,y=1-1/(1+e-z)regression equation to build a prediction model.The stability of the model was verified by cross-checking method. RESULTS AND CONCLUSION:(1)Classification of talus osteochondral injury in 154 patients(type Ⅰ:36 cases;type Ⅱ:37 cases;type Ⅲ:40 cases;type Ⅳ:41 cases),T1ρ and T2 values of the four groups were statistically significant(P<0.05);pairwise comparison was also statistically significant(all P<0.05).(2)After treatment of 154 patients,7 cases(4.6％)had local swelling,3 cases(2.0％)had pain aggravation,and 5 cases(3.3％)had wound infection.There were 2 cases(1.3％)with poor cartilage healing.(3)After treatment,there were statistically significant differences between groups A and B in terms of American Orthopaedic Foot&Ankle Society score,visual analog scale score,plantar flexor motion range,dorsoextension motion range,subchondral bone marrow edema volume,interleukin-6,interleukin-8,C-reactive protein,procalcitonin,platelet-derived growth factor,transforming growth factor-β1,and efficacy(P<0.05).The total effective rate of group B(90％)was higher than that of group A(85％)(P<0.05).(4)Age(OR=1.589,95％CI:0.305-1.252,P=0.036),interleukin-6(OR=1.737,95％CI:0.974-5.254,P=0.049),interleukin-8(OR=1.385,95％CI:1.066-4.355,P=0.034),C-reactive protein(OR=1.957,95％CI:1.323-2.178,P=0.035),transforming growth factor-β1(OR=1.459,95％CI:0.897-2.455,P=0.038),T1-ρ(OR=1.687,95％CI:0.854-3.321,P=0.026),T2(OR=1.843,95％CI:0.657-2.454,P=0.036),complications(OR=1.719,95％CI:0.654-3.464,P=0.019),and classification of osteochondral injury of talus(OR=3.789,95％CI:1.023-5.897,P=0.028)were independent risk factors for postoperative recurrence.Microfracture surgery(OR=0.751,95％CI:0.321-1.264,P=0.012)and autogenous bone and cartilage grafting(OR=0.649,95％CI:0.246-1.356,P=0.023)were independent protective factors for recurrence after medium-and long-term follow-up.(5)When T1ρ value≤35 ms,the risk of postoperative recurrence decreased rapidly,and when T1ρ value>35 ms,the risk of postoperative recurrence increased rapidly.(6)Further stepwise regression analysis showed that these nine risk factors were most closely associated with postoperative recurrence,and the formula for postoperative recurrence was obtained.The probability of postoperative recurrence was calculated using the regression equation.When P=0.75,the maximum value of Jorden index was 77.728,indicating that the model has a better prediction effect.(7)It is indicated that the quantitative evaluation of T1ρ before operation can effectively guide the selection of surgical methods,improve the success rate of surgery and the quality of life of patients.

OBJECTIVE: To investigate the effectiveness of sagittal top compression reduction technique in the treatment of thoracolumbar vertebral fractures. METHODS: A retrospective analysis was conducted on the clinical data of 59 patients with thoracolumbar vertebral fractures who met the selection criteria and were admitted between November 2018 and January 2022. Among them, 34 patients were treated with sagittal top compression reduction technique (top pressure group), and 25 patients were treated with traditional reduction technique (traditional group). There was no significant difference in baseline data between the two groups ( P>0.05), including gender, age, fracture segment, cause of injury, AO classification of thoracolumbar vertebral fractures, thoracolumbar injury classification and severity (TLICS) score, American Spinal Injury Association (ASIA) grading, surgical approach, preoperative vertebral body index, height ratio of the anterior margin of injured vertebra, injured vertebra angle, segmental kyphosis angle, visual analogue scale (VAS) score, and Oswestry disability index (ODI). The operation time, intraoperative blood loss, and incidence of complications between the two groups were recorded and compared. After operation, VAS score and ODI were used to evaluate effectiveness, and X-ray and CT examinations were performed to measure imaging indicators such as vertebral body index, height ratio of the anterior margin of injured vertebra, injured vertebra angle, and segmental kyphosis angle. RESULTS: There was no significant difference in operation time and intraoperative blood loss between the two groups ( P>0.05). No complication such as dural sac, nerve root, or vascular injury was found during operation, and all incisions healed by first intention. Patients in both groups were followed up 6-48 months, with an average of 20.6 months. No loosening, breakage, or failure of internal fixation occurred during follow-up. The imaging indicators, VAS score, and ODI of the two groups significantly improved at 1 week and last follow-up when compared to preoperative ones ( P<0.05). At last follow-up, the VAS score and ODI further significantly improved when compared to 1 week after operation ( P<0.05). At 1 week after operation and last follow-up, the vertebral body index, segmental kyphosis angle, injured vertebra angle, and ODI in the top pressure group were significantly better than those in the traditional group ( P<0.05). There was no significant difference in VAS score and height ratio of the anterior margin of injured vertebra between the two groups at 1 week after operation ( P>0.05), but the two indicators in the top pressure group were significantly better than those in the traditional group at last follow-up ( P<0.05). CONCLUSION The treatment of thoracolumbar vertebral fractures with sagittal top compression reduction technique can significantly improve the quality of vertebral reduction, and is superior to traditional reduction techniques in relieving pain and improving spinal function.

Objective:To analyze the efficacy and safety of enzyme replacement therapy (ERT) in Chinese patients with Fabry disease.Methods:A retrospective analysis of the clinical manifestations, genetic variations, family screening, treatments and adverse reactions was conducted in five patients with Fabry disease admitted to the First Affiliated Hospital of Zhejiang University College of Medicine from July 2020 to May 2021. The dosage of agalsidase β was 1 mg/kg by intravenous pump once every 2 weeks.Results:Five male patients with median age of 37 years old (29-51 years old) were diagnosed based on clinical features, family history, α-galactosidase A (α-Gal A) activity, genetic analysis results and kidney biopsy. The clinical manifestations varied in these five patients. All patients had abnormal electrocardiogram, abnormal cardiac ultrasonography and abnormal urinalysis results, three experienced acroparaesthesia during childhood (one patient had persistent pain until adulthood), three had cutaneous angiokeratoma, four had renal insufficiency, four had hypohidrosis, four had diarrheas, four had cornea verticillata and two had high-frequency hearing loss. Two missense mutations of the GLA gene were identified: c.272T>C(p.I91T) and c.868A>G(p.Met290Val). Two nonsense mutations were c.1024C>T(p.Arg342*) and c.838C>T(p.Gln280*). Furthermore, the frameshift mutation c.348del p.(Ile117Phefs*4) was detected, which was not included in the known database, presented with classical Fabry disease. There was no serious adverse reaction during agalsidase β infusion in 5 patients. ERT reduced the plasma globotriaosylsphingosine (lyso-GL-3) levels after treatment of 2-10 months ( P<0.05), and the long-term diarrhea symptom were significantly improved. Conclusions:The clinical manifestations of Fabry disease are varied. Severe adverse events rarely occur in patients treated with short-term ERT. Plasma lyso-GL-3 levels decrease significantly after treatment.

Objective:To explore the value of detecting plasma donor-derived free DNA (dd-cfDNA) fraction in distinguishing antibody mediated-rejection (ABMR) and T cell-mediated rejection (TCMR) of renal allografts.Methods:Patients with acute rejection confirmed by allograft biopsy in the First Affiliated Hospital of Medical College of Zhejiang University from December 1, 2017 to July 18, 2019 were retrospectively included. Based on pathological classification of Banff renal allograft rejection in 2017, the patients were divided into ABMR group and TCMR group, and the latter was subdivided into TCMR Ⅰ subgroup and TCMR Ⅱ subgroup. The second generation sequencing and target region capture were used to detect candidates' peripheral blood dd-cfDNA. The demographic and clinicopathological data of the two groups were compared. The receiver operating characteristic curve (ROC) was used to evaluate the differential value of plasma dd-cfDNA and serum creatinine levels in two kinds of acute renal allograft rejection.Results:A total of 60 patients with acute rejection of renal transplantation were enrolled in this study, including 42 patients in TCMR group and 18 patients in ABMR group. The plasma dd-cfDNA percentage (%) in the ABMR group was significantly higher than that in the TCMR group [2.33(1.19, 4.30)% vs 0.98(0.50, 1.82)%, P=0.001]. The absolute value of dd-cfDNA in ABMR group was obviously higher than that in TCMR group [0.94(0.60, 2.27) ng/ml vs 0.43(0.20, 0.96) ng/ml, P=0.003]. ROC analysis to discriminate TCMR from ABMR showed that, the area under the curve ( AUC) of dd-cfDNA% was 0.76(95% CI 0.64-0.88), when the threshold was 1.11%, the sensitivity and specificity were 88.89% and 59.52%, respectively; the AUC of absolute value of dd-cfDNA was 0.74(95% CI 0.61-0.86), when the threshold was 0.53 ng/ml, the sensitivity was 88.89% and the specificity was 54.76%. TCMR subgroups were further analyzed, there was no significant difference between TCMR subgroups on the absolute value and percentage of dd-cfDNA (both P>0.05); dd-cfDNA% in ABMR group was apparently higher than that in TCMRⅠ subgroups ( P=0.008) and TCMRⅡsubgroup ( P=0.030). The absolute value of dd-cfDNA in ABMR group was significantly higher than that in TCMRⅠsubgroups ( P=0.003). Conclusion:Plasma dd-cfDNA level may help to distinguish between ABMR and TCMR rejection.

Objective:To investigate the value of routine echocardiography and two-dimensional speckle tracking echocardiography in evaluating the left ventricular function of patients with gestational diabetes mellitus (GDM) prenatal and postpartum.Methods:Twenty-two patients with clinically confirmed GDM in Xiamen Zhongshan Hospital from October 2019 to December 2020 were chosed as the case group, and 22 healthy pregnant women were chosed as the control group. Routine echocardiography and two-dimensional speckle tracking echocardiography were performed in the third trimester and about 3 months postpartum. Routine echocardiographic parameters and longitudinal strain (LS), circumfirential strain (CS) were obtained. The correlation between global longitudinal strain(GLS) and other cardiac function parameters was analyzed. The relationship between clinical parameters of pregnant women and GLS was analyzed by multiple linear regression.Results:In comparison with the control group, the interventricular septal diameter at disatole, left ventricular posterior wall diameter at diastole, Tei index were increased, e′ was decreased in GDM group(all P<0.05); the GLS, each layer LS of GDM group were lower than the control group(all P<0.05), the GLS, each layer LS and torsion parameters were improved at 3 months postpartum(all P<0.05). There was a negative correlation between GLS and Tei( r=-0.224, P=0.036). GLS and HbA 1c was linearly correlated with the regression equation: GLS=-27.458+ 1.534×HbA 1c( R2=0.115). Conclusions:The left heart function of pregnant women with GDM in the third trimester are significantly impaired, but the cardiac function recovers to a certain extent about 3 months after delivery. Two-dimentional speckle-tracking echocardiography is a more accurate and sensitive technique to evaluate the early damage of cardiac function in pregnant women with GDM.
