Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.

Objective To evaluate adverse events(AEs)of hematological toxicities in cyclin-dependent kinase 4/6(CDK4/6)inhibitors based on the FDA adverse event reporting system(FAERS)database,and to provide a reference for rational drug use in the clinic.Methods A total of 29 quarterly AEs were extracted from the FAERS database from January 2015 to March 2022.Reported odds ratio(ROR)and proportional reported ratio(PRR)were used for data mining of CDK4/6 inhibitor AEs.Results A total of 7 872 AEs related to CDK4/6 inhibitors were reported,and the proportion of hematological AEs of each inhibitor was palbociclib(80.31%),ribociclib(15.36%),and abemaciclib(4.33%).Neutropenia and anemia were common in hematological toxicities.Palbociclib(2 982/6 322,47.17%)and ribociclib(613/1 209,50.70%)caused more neutropenia than abemaciclib(117/341,34.31%).Hematological toxicities mainly occurred 60 days after drug initiation(1 630,61.86%).Palbociclib had the longest median onset time,and 32.9%of patients still had hematological toxicities after 90 days of treatment.The clinical features and intensity were different among CDK4/6 inhibitors.Conclusions Palbociclib,abemaciclib,and ribociclib all cause significant hematological toxicities,among which abemaciclib has fewest reports of hematological toxicities.Still,the risk of death after anemia caused by abemaciclib should be noted.Complete blood cell count should be closely monitored within the first two months after treatment to monitor the patient's neutrophils and hemoglobin.The occurrence of hematological AEs associated with CDK4/6 inhibitors should be noted in the clinic.

Objective:To predict the 3-year cancer-specific survival(CSS)of patients with non-meta-static T3a renal cell carcinoma after surgery.Methods:A total of 336 patients with pathologically con-firmed T3a N0-1M0 renal cell carcinoma(RCC)who underwent surgical treatment at the Department of Urology,Peking University Third Hospital from March 2013 to February 2021 were retrospectively collect-ed.The patients were randomly divided into a training cohort of 268 cases and an internal validation co-hort of 68 cases at an 4∶1 ratio.Using two-way Lasso regression,variables were selected to construct a nomogram for predicting the 3-year cancer-specific survival(CSS)of the patients with T3aN0-1M0 RCC.Performance assessment of the nomogram included evaluation of discrimination and calibration ability,as well as clinical utility using measures such as the concordance index(C-index),time-dependent area un-der the receiver operating characteristic curve[time-dependent area under the curve(AUC)],calibra-tion curve,and decision curve analysis(DCA).Risk stratification was determined based on the nomo-gram scores,and Kaplan-Meier survival analysis and Log-rank tests were employed to compare progres-sion-free survival(PFS)and cancer-specific survival(CSS)among the patients in the different risk groups.Results:Based on the Lasso regression screening results,the nomogram was constructed with five variables:tumor maximum diameter,histological grading,sarcomatoid differentiation,T3a feature,and lymph node metastasis.The baseline data of the training and validation sets showed no statistical differences(P＞0.05).The consistency indices of the column diagram were found to be 0.808(0.708-0.907)and 0.903(0.838-0.969)for the training and internal validation sets,respectively.The AUC values for 3-year cancer-specific survival were 0.843(0.725-0.961)and 0.923(0.844-1.002)for the two sets.Calibration curves of both sets demonstrated a high level of consistency between the actual CSS and predicted probability.The decision curve analysis(DCA)curves indicated that the column dia-gram had a favorable net benefit in clinical practice.A total of 336 patients were included in the study,with 35 cancer-specific deaths and 69 postoperative recurrences.According to the line chart,the patients were divided into low-risk group(scoring 0-117)and high-risk group(scoring 119-284).Within the low-risk group,there were 16 tumor-specific deaths out of 282 cases and 36 postoperative recurrences out of 282 cases.In the high-risk group,there were 19 tumor-specific deaths out of 54 cases and 33 post-operative recurrences out of 54 cases.There were significant differences in progression-free survival(PFS)and cancer-specific survival(CSS)between the low-risk and high-risk groups(P＜0.000 1).Conclusion:A nomogram model predicting the 3-year CSS of non-metastatic T3a renal cell carcinoma patients was successfully constructed and validated in this study.This nomogram can assist clinicians in accurately assessing the long-term prognosis of such patients.

OBJECTIVE To explore the construction of mind map by clinical pharmacists for the consultation of pulmonary nocardiosis and its application in clinical practice， and to provide reference for promoting the correct selection of nocardiosis treatment drugs in clinical practice and ensuring drug safety and efficacy. METHODS A total of 7 patients with Nocardia pulmonary infection from January 2017 to April 2022 in our hospital were collected. Based on evidence-based medicine， a consultation mind map （mainly including understanding the medical history， identifying infectious bacteria， identifying risk factors， developing treatment plans， and conducting evaluations） was constructed to address the difficulties of large differences in drug sensitivity among different strains of Nocardia and numerous adverse reactions of Compound sulfamethoxazole as a first-line drug. The treatment plan was developed for 7 patients with pulmonary nocardiosis， and whole-process pharmaceutical care was provided. RESULTS Combined with the mind map， different antibiotic combination regimens were given according to the drug sensitivity results of Nocardia， the different species of Nocardia， and the patient’s allergy history. Among them， 4 cases were treated with imipenem cilastatin， the patients receiving Compound sulfamethoxazole and linezolid for a long time were given full pharmaceutical care， and the adverse drug reactions were timely treated.CONCLUSIONS Clinical pharmacists apply the consultation mind map of pulmonary nocardiosis to the treatment of inpatients， take advantage of pharmacy， participate in clinical drug therapy， and really play a role in the clinical treatment team so as to promote rational drug use.

OBJE CTIVE To explore the rational application and management of antibiotics in burn department of our hospital based on disease diagnosis related groups （DRGs）. METHODS Patients discharged from the burn department of our hospital from July 2020 to June 2021 were selected as the research objects to collect DRG data. The overall application of antibiotics in DRG group with more than 10 cases were analyzed ，and the application of antibiotics in typical disease groups were evaluated horizontally and vertically. RESULTS Among 3 732 discharged cases in the burn department of our hospital ，a total of 3 515 cases were included in 66 DRG groups ，21 DRG groups of which were included in the study. Among 21 DRG groups ，the maximum antibiotics use density （AUD）of antibiotics was 102.20 DDDs/（100 person·d）in AH 11 group，the utilization ratio of antibiotics was 100％，and the combined use rate of antibiotics was 81.82％；case-mix index （CMI）value was 11.49. The minimum AUD was 1.01 DDDs/（100 person·d）in XR 19 group，the utilization ratio of antibiotics was 5.06％，and the combined use rate of antibiotics was 0；CMI value was 0.81. Within the same core group ，AUD increased with the increase of CMI. The horizontal comparison and analysis of WB 11 group showed that there was a large gap in AUD among different physicians. The vertical comparison of AUD in WB11 group showed relatively small changes over time. CONCLUSIONS The horizontal and vertical evaluation of antibiotics based on DRGs can provide new clues for the control of antibiotics and help to realize the fine specialized management of antibiotics.

Objective:To summarize the anesthesia management of living small bowel transplantation.Methods:Severn patients undergoing living and allogeneic small bowel transplantation for the first time were selected.The intraoperative hemodynamics, indexes of blood gas analysis, body temperature and blood transfusion and volume of liquid infused were analyzed.Postoperative outcomes were tracked.Results:Six cases survived and were successfully discharged from hospital successfully, and one patient died.In the operation room, 71% patients were successfully extubated after surgery.Compared with the values during anatomical separation period, Hb during vascular anastomosis and intestinal reconstruction periods and concentration of Ca 2+ during intestinal reconstruction period were significantly decreased, and the blood glucose concentration during vascular anastomosis period were increased ( P<0.05 or 0.01). Compared with the values during vascular anastomosis period, the blood glucose concentration was increased significantly during intestinal reconstruction period ( P<0.05). Crystalloid solution (57±30) ml/kg and colloid solution which mainly containing 20% albumin (15±13) ml/kg were infused mainly during anatomical separation and vascular anastomosis periods in all the patients. Conclusion:The condition of successful living small bowel transplantation is fully evaluation and preparation before surgery.Intravenous-inhalational anesthesia combined with transverses abdominis plane block and rational infusion of colloid solution with vasoactive drugs to maintain hemodynamics stability and monitor blood gas, body temperature, active adjustment of electrolytes and internal environment and stable body temperature can be helpful in maintaining perioperative stable vital signs during the perioperative period, removing the tracheal tube early at the end of surgery, and reducing the development of postoperative complications in patients undergoing living small bowel transplantation.

The newly reported HIV infected cases was collected, and HIV blood samples were detected to identify recent HIV infection in Tianjin during 2008-2015. Factors associated with HIV-1 infection were analyzed by the univariate and multivariate unconditional logistic regression. The recent HIV-1 infection proportion of homosexuals increased from 37.70% in 2008 to 83.68% in 2015. Those cases who aged ≤30 years (OR=1.53, 95%CI: 1.30-1.79), in han ethnic group (OR=1.40, 95%CI: 1.02-1.91), students (OR=1.79, 95%CI: 1.28-2.51) were more likely to be recent infected. The cases who had a high school education (OR=1.28, 95%CI: 1.05-1.56) or collage education (OR=1.23, 95%CI: 1.00-1.50) were more likely to be recent infected than those who had a primary school education. Compared with patients identified by hospitals, the recent HIV infections were more likely to be found through voluntary counseling and testing (VCT), STD outpatients, men who have sex with men (MSM) investigation and unpaid blood donors. Homosexual transmission has become the major route of HIV-1 recent infection in Tianjin.

To analyze the incidence and imaging characteristics of pulmonary nodules in a unit staff.
 Methods: Low-dose spiral CT (LDCT) scan were performed in 1 372 staffs ≥45 years old in a certain unit during the physical examination. The clinical and imaging data were collected to analyze the detection rate, imaging characteristics, and postoperative pathological conditions of pulmonary nodules.
 Results: The total detection rate for pulmonary nodules was 30.39% (417/1 372). The detected nodules were mainly single (227 cases), solid (343 cases), <5 mm in diameter (261 cases), and Lung-Reporting and Data System (Lung-RADS) category 2 nodules (340 cases). The single nodules were mostly found in the right upper lung (74 cases, 32.60%). The detection rate of pulmonary nodules tended to decrease but the detection rate of category 4 nodules increased with the increasing age (P<0.05), while the gender had no significant influence on the detection rate (P>0.05). Compared with the Lung-RADS category 3 nodules, the proportions of nodules in subsolid state, with irregular shape, lobulation sign, and vascular penetration in the Lung-RADS category 4 were increased (all P<0.05). Among them, 11 patients received surgical therapy, including 10 women. Postoperative pathology confirmed lung adenocarcinoma in 9 patients (2.16%), including 8 women, all non-smokers.
 Conclusion: The nodules in subsolid state with vascular penetration, irregular shape and lobulation sign tend to be malignant. Lung cancer screening with low-dose spiral CT in female non-smokers should be emphasized.
