OBJECTIVE To provide empirical basis for promoting the dynamic adjustment of the pharmaceutical care catalogue and the formulation of policies such as hierarchical payment of medical insurance. METHODS A multicenter cross- sectional survey method was adopted to conduct a questionnaire survey among 424 inpatients in 22 tertiary medical institutions in 12 prefecture-level cities of Hubei Province to evaluate their demand for pharmaceutical care， willingness to pay and preference for service forms. Combined with univariate and multivariate Logistic regression analysis， the influencing factors and key factors that affect patients’ willingness to pay for pharmaceutical care were identified. RESULTS Only 39.86% of the patients were aware of pharmaceutical care or pharmacists， and 89.62% of the patients hope to receive pharmaceutical care. Among the 16 types of pharmaceutical care， the patients surveyed had a relatively high recognition rate for guidance on drug usage and dosage， notification of medication precautions， and the identification， prevention and handling of adverse drug reactions. 96.70%， 95.30%， and 94.12% respectively expressed strong approval and approval. The demand for services such as insurance-related policy consultation， popular science on the mechanism of drug action， and assessment of the combined use of traditional Chinese and Western medicines was relatively low， with 61.65%， 68.47%， and 68.47% expressing strong approval and approval respectively. The positive influencing factors of willingness to pay were household monthly income ＞ 5 000 yuan （OR＝1.742）， awareness of pharmaceutical care or pharmacists （OR＝3.620）， and the desire to receive pharmaceutical care （OR＝4.686） （P＜0.05）， while self-rating health as “good” （OR＝0.390） was a negative influencing factor （P＜0.05）. Cardiovascular and cerebrovascular diseases （54.48%） and antihypertensive drugs （45.05%） were the service scenarios that the surveyed patients most hope to be covered. 85.14% of the patients preferred “service when xiaochnye@126.com needed”， with a single service duration of less than 10 minutes being appropriate （84.43%）， and the willingness to pay within 20 yuan being the main type （85.38%）. CONCLUSIONS Based on the characteristics of patients’ needs and payment behaviors， it is suggested that our country could consider establishing a hierarchical payment mechanism for pharmaceutical care， and focus on differentiated design in combination with diseases and medication situations. At the same time， the rights， responsibilities and service standards of resident pharmacists in the links such as medication reorganization and medical order review should be further clarified to comprehensively enhance the clinical value and policy operability of pharmaceutical care.

Objective:To investigate the effect of different surgical timing on the surgical treatment of renal angiomyolipoma(RAML)with rupture and hemorrhage.Methods:The demographic data and peri-operative data of 31 patients with rupture and hemorrhage of RAML admitted to our medical center from June 2013 to February 2023 were collected.The surgery within 7 days after hemorrhage was defined as a short-term surgery group,the surgery between 7 days and 6 months after hemorrhage was defined as a me-dium-term surgery group,and the surgery beyond 6 months after hemorrhage was defined as a long-term surgery group.The perioperative related indicators among the three groups were compared.Results:This study collected 31 patients who underwent surgical treatment for RAML rupture and hemorrhage,of whom 13 were males and 18 were females,with an average age of(46.2±11.3)years.The short-term surgery group included 7 patients,the medium-term surgery group included 12 patients and the long-term surgery group included 12 patients.In terms of tumor diameter,the patients in the long-term surgery group were significantly lower than those in the recent surgery group[(6.6±2.4)cmvs.(10.0±3.0)cm,P=0.039].In terms of operation time,the long-term surgery group was significantly shorter than the mid-term surgery group[(157.5±56.8)min vs.(254.8±80.1)min,P=0.006],and there was no sig-nificant difference between other groups.In terms of estimated blood loss during surgery,the long-term surgery group was significantly lower than the mid-term surgery group[35(10,100)mL vs.650(300,1 200)mL,P＜0.001],and there was no significant difference between other groups.In terms of intraoperative blood transfusion,the long-term surgery group was significantly lower than the mid-term surgery group[0(0,0)mL vs.200(0,700)mL,P=0.014],and there was no significant difference between other groups.In terms of postoperative hospitalization days,the long-term surgery group was sig-nificantly lower than the mid-term surgery group[5(4,7)d vs.7(6,10)d,P=0.011],and there was no significant difference between other groups.Conclusion:We believe that for patients with RAML rupture and hemorrhage,reoperation for more than 6 months is a relatively safe time range,with minimal intraoperative bleeding.Therefore,it is more recommended to undergo surgical treatment after the hema-toma is systematized through conservative treatment.

BACKGROUND:Indolepropionic acid has been shown to reduce diabetes-induced central nervous system inflammation.However,there is a lack of research on whether to inhibit microglia M1 polarization for the treatment of spinal cord injury. OBJECTIVE:To investigate the mechanism of indolepropionic acid inhibition of microglial cell M1 polarization for the treatment of spinal cord injury through cell and animal experiments. METHODS:(1)In vitro experiments:BV2 cell viability was assessed using the CCK-8 assay to determine optimal concentrations of indolepropionic acid.Subsequently,BV2 cells were categorized into control group,administration group(50 μmol/L indolepropionic acid),lipopolysaccharide group(100 ng/mL lipopolysaccharide),and treatment group(100 ng/mL lipopolysaccharide + 50 μmol/L indolepropionic acid).Nitric oxide content was quantified using the Griess method.Real-time quantitative PCR and western blot assay were employed to measure mRNA and protein levels of pro-inflammatory factors.Cell immunofluorescence staining was conducted to assess inducible nitric oxide synthase expression.The Seahorse assay was employed to assess glycolytic stress levels in BV2 cells.(2)In vivo experiments:30 SD rats were randomly divided into three groups:sham surgery group,spinal cord injury group,and indolepropionic acid group.Motor function recovery in rats after spinal cord injury was assessed using BBB scoring and the inclined plane test.Immunofluorescence staining of spinal cord tissue was conducted to evaluate the expression of inducible nitric oxide synthase in microglial cells.ELISA was employed to measure protein expression levels of the pro-inflammatory cytokines interleukin-1β and tumor necrosis factor-α in spinal cord tissue. RESULTS AND CONCLUSION:(1)In vitro experiments:Indolepropionic acid exhibited significant suppression of BV2 cell viability when its concentration exceeded 50 μmol/L.Indolepropionic acid achieved this by inhibiting the activation of the nuclear factor κB signaling pathway,thereby suppressing the mRNA and protein expression levels of pro-inflammatory cytokines(interleukin-1β and tumor necrosis factor-α),as well as the M1 polarization marker,inducible nitric oxide synthase,in BV2 cells.Additionally,indolepropionic acid notably reduced the glycolytic level in BV2 cells induced by lipopolysaccharides.(2)In vivo experiments:Following indolepropionic acid intervention in spinal cord injury rats,there was a noticeable increase in BBB scores and the inclined plane test angle.There was also a significant decrease in the number of M1-polarized microglial cells in spinal cord tissue,accompanied by a marked reduction in the protein expression levels of pro-inflammatory cytokines(interleukin-1β and tumor necrosis factor-α).(3)These results conclude that indolepropionic acid promotes functional recovery after spinal cord injury by improving the inflammatory microenvironment through inhibition of microglia M1 polarization.

[Objective] To review the clinical information, imaging features, pathological manifestations and prognosis of low-grade oncocytic tumor (LOT), so as to improve the clinical understanding of the disease. [Methods] The imaging, clinicopathological and postoperative follow-up data of 3 LOT cases treated in Peking University Third Hospital during Feb.2020 and Sep.2022 were retrospectively collected. [Results] All patients were male, aged 51—70 years.All tumors were single, with the maximum diameter of 14—21 mm. None of the patients had any specific clinical manifestations.The mass showed a circular isodense shadow on CT.All patients underwent nephron-sparing tumor resection.Postoperative pathology showed that the incision surface of the tumors was brownish-yellow or brown, and the tumors were solid or partially cystic.HE staining showed that the cells were uniformly eosinophilic; the nucleus was round or oval, with slight local perinuclear halo.Immunohistochemistry showed positive CK7 but negative CD117.Genetic testing in case 2 showed 1 potentially clinically significant somatic mutation TSC2.During the follow-up of 12-23 months, no recurrence occurred. [Conclusion] There were no obvious clinical symptoms and imaging features of LOT, which morphologically showed heterozygous or borderline characteristics with renal eosinophilia and renal chromophobe cell carcinoma, and the biological behavior was indolent.Nephron-sparing tumor resection promised good prognosis.

Objective:To summarize the clinical characteristics of patients with renal angiomyolipoma(RAML)combined with inferior vena cava(IVC)tumor thrombus,and to explore the feasibility of par-tial nephrectomy and thrombectomy in this series of patients.Methods:The clinical data of patients diagnosed with RAML combined with IVC tumor thrombus in the Department of Urology of the Peking University Third Hospital from April 2014 to March 2023 were retrospectively analyzed,and demographic and perioperative data of RAML patients with IVC tumor thrombus were recorded and collected from Elec-tronic Medical Record System,including age,gender,surgical methods,and follow-up time,etc.The clinical characteristics between classic angiomyolipoma(CAML)patients with IVC tumor thrombus and epithelioid angiomyolipoma(EAML)patients with IVC tumor thrombus were compared to determine the clinical characteristics of these patients.Results:A total of 11 patients were included in this study,in-cluding 7 patients with CAML with IVC tumor thrombus and 4 patients with EAML with IVC tumor thrombus.There were 9 females(9/11,81.8％)and 2 males(2/11,18.2％),with an average age of(44.0±17.1)years.9 patients(9/11,81.8％)experienced clinical symptoms,including local symp-toms including abdominal pain,hematuria,abdominal masses,and systemic symptoms including weight loss and fever;2 patients(2/11,18.2％)with RAML and IVC tumor thrombus did not show clinical symptoms,which were discovered by physical examination.Among the 11 patients,10 underwent radical nephrectomy with thrombectomy,of whom,3 underwent open surgery(3/10,30.0％),2 underwent laparoscopic surgery(2/10,20.0％),and 5 underwent robot-assisted laparoscopic surgery(5/10,50.0％).In addition,1 patient underwent open partial nephrectomy and thrombectomy.The patients with EAML combined with I VC tumor thrombus had a higher proportion of systemic clinical symptoms(100％vs.0％,P=0.003),more intraoperative bleeding[400(240,3 050)mL vs.50(50,300)mL,P=0.036],and a higher proportion of tumor necrosis(75％vs.0％,P=0.024)compared to the patients with CAML combined with I VC tumor thrombus.However,there was no statistically significant difference in operation time[(415.8±201.2)min vs.(226.0±87.3)min,P=0.053]between the two groups.Conclusion:Compared with the patients with CAML and IVC tumor thrombus,the patients with EAML and IVC tumor thrombus had a higher rate of systemic symptoms and tumor necrosis.In addi-tion,in the selected patients with CAML with IVC tumor thrombus,partial nephrectomy and tumor thrombectomy could be performed to better preserve renal function.

Objective:To analyze the clinicopathological characteristics and prognosis of patients with multilocular cystic renal neoplasm of low malignant potential and compare the clinicopathological charac-teristics of patients with multilocular cystic renal neoplasm of low malignant potential who underwent different surgical methods.Methods:Clinicopathological data and prognosis of patients admitted to Peking University Third Hospital from January 2010 to September 2023 were collected.Patients who underwent radical nephrectomy or nephron-sparing surgery and were pathologically diagnosed with multilocular cystic renal neoplasm of low malignant potential were identified.Based on the surgical methods,the patients were divided into radical nephrectomy group and nephron-sparing surgery group.The clinicopathological characteristics of the two groups were compared.Results:A total of 35 patients were enrolled in this study.The median age at diagnosis was 53.0(39.0-62.0)years.Among the 35 patients,23 were males(65.7％)and 12 were females(34.3％).Nine patients underwent radical nephrectomy(25.7％),while 26 patients underwent nephron-sparing surgery(74.3％).The clinical T-stage of 35 patients did not exceed T2a stage.The median operation time was 145.0 min,and the median estimated intraoperative blood loss was 20.0 mL.The median postoperative hospitalization days was 6.0 d.The postoperative pathological results did not indicate renal sinus invasion,sarcomatous change,adrenal invasion or lymph node invasion.Based on the surgical methods,the patients were divided into a radical nephrectomy group and a nephron-sparing surgery group.There was no significant difference in clinicopathological charac-teristics between the two groups.Except for one patient who was lost to the follow-up,all the other patients were followed up for 8-111 months,with a median follow-up time of 70.5 months.Only one patient died from non-cancer-specific reasons,other patients had no tumor metastasis or recurrence.Conclusion:Patients with multilocular cystic renal neoplasm of low malignant potential have a good prog-nosis.There is no significant difference in clinicopathological characteristics of patients between nephron-sparing surgery group and radical nephrectomy group for multilocular cystic renal neoplasm of low malig-nant potential.

Objective:To investigate the postoperative renal function and oncologic outcomes of cystic renal cell carcinoma with partial nephrectomy,and to compared the single-center data on surgical out-comes with the Surveillance,Epidemiology,and End Results(SEER)database.Methods:This was a retrospective study that included the patients with cystic renal cell carcinoma who underwent partial ne-phrectomy in the Department of Urology,Peking University Third Hospital(PUTH)from 2010 to 2023.The clinical data and depicting baseline characteristics were collected.Renal dynamic imaging and the Chinese Coefficients for Chronic Kidney Disease Epidemiology Collaboration(C-CKD-EPI)formulae were used to calculate the estimated glomerular filtration rate(eGFR).The renal function curves over time were then plotted,and the patients were followed-up to record their survival status.Cases of cystic renal cell carcinoma in the SEER database between 2000 and 2020 were included,propensity score matching(PSM)was performed to balance the differences between SEER cohort and PUTH cohort,and the cancer-specific survival(CSS)curves for both groups were plotted and statistical differences were calcu-lated by the Kaplan-Meier method.Results:A total of 38 and 385 patients were included in the PUTH cohort and SEER cohort,respectively,and 31 and 72 patients were screened in each cohort after PSM.Of the baseline characteristics,only tumor size(P=0.042)was found to differ statistically between the two groups.There was no statistically significant difference between the two cohorts in terms of CSS after PSM(P=0.556).The median follow-up time in the SEER cohort was 112.5(65,152)months and a 10-year survival rate of 97.2％,while the PUTH cohort had a median follow-up of 57.0(20,1 172)months and a 10-year survival rate of 100.0％.There was no statistically significant difference between eGFR determined by preoperative renal dynamic imaging and the results of the C-CKD-EPI formulae based on creatinine estimation(P=0.073).There was a statistically significant difference in eGFR among the preoperative,short-term postoperative,and long-term postoperative(P＜0.001),which was characterized by the presence of a decline in renal function in the short-term postoperative period and the recovery of renal function in the long-term period.Conclusion:Partial nephrectomy for cystic renal cell carcinoma is safe and feasible with favorable renal function and oncologic outcomes.

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.

Objective:To investigate the clinicopathological characteristics and prognosis of pT 3a stage non-clear cell renal cell carcinoma (nccRCC). Methods:The clinical data of 438 patients with pT 3a stage renal cell carcinoma treated by surgery at Peking University Third Hospital from March 2013 to March 2023 were retrospectively analyzed. Among them, there were 58 cases in the nccRCC group and 380 cases in the clear cell RCC (ccRCC) group. There were statistically significant differences in age, American Society of Anesthesiologists (ASA) classification, and comorbidities between the two groups (all P<0.05). Therefore, propensity score matching was used to adjust the baseline data of the two groups. After matching, there were 58 cases in the nccRCC group and 232 cases in the ccRCC group. There were no statistically significant differences in gender (male/female: 34/24 cases and 165/67 cases), age (53.3±16.8 years and 56.6±11.6 years), ASA classification (1/2/3/4: 19/34/5/0 cases and 60/163/8/1 cases), comorbidities (present/absent: 16/42 cases and 76/156 cases), tumor maximum diameter [6.7 (5.3, 8.4) cm and 5.8 (4.6, 7.8) cm], and nephron sparing surgery(yes/no: 4/54 cases and 15/217 cases) (all P > 0.05). The overall survival (OS) and progression-free survival (PFS) of two groups were compared, the Kaplan-Meier method was employed to plot survival curves. Cox proportional hazards regression model was used to analyze the relationship between different pT 3a characteristics in the nccRCC group and progression-free survival. Results:In the matched cohort, the median follow-up time for the nccRCC group and ccRCC group were 28.0 (16.3, 45.3) months and 31.0 (18.0, 57.0) months, respectively. The pathological types in the nccRCC group included chromophobe renal cell carcinoma (20 cases, 34.5%), papillary renal cell carcinoma (20 cases, 34.5%), Xp11.2 translocation renal cell carcinoma (8 cases, 13.8%), mucinous tubular and spindle cell carcinoma (3 cases, 5.2%), and other or unclassified renal cell carcinoma (7 cases, 12.1%). There was no statistical significance between the nccRCC and ccRCC groups in terms of invasion of the renal vein without involvement of the vein wall (yes/no: 5/53 cases and 41/191 cases), vascular invasion (yes/no: 18/40 cases and 52/180 cases), invasion of the perirenal fat (yes/no: 15/43 cases and 39/193 cases), invasion of the renal pelvis and sinus (yes/no: 51/7 cases and 200/32 cases), or sarcomatoid differentiation (yes/no: 2/56 cases and 4/228 cases)(all P > 0.05). However, there was a statistically significant difference in lymph node involvement (yes/no: 3/229 cases and 9/49 cases, P < 0.01). The 5-year PFS and OS of nccRCC group were 67% (95% CI 52%-86%) and 70% (95% CI 55%-89%) respectively. While the 5-year PFS and OS of ccRCC group were 78% (95% CI 70%-86%) and 87% (95% CI 81%-93%) respectively. There was no statistically significant difference in PFS between the two groups ( P>0.05), but there was a statistically significant difference in OS ( P<0.01). Furthermore, within specific pathological types, the 5-year PFS and OS rates of chromophobe renal cell carcinoma were 88% (95% CI 67%-100%) and 86% (95% CI 63%-100%) respectively, followed by papillary renal cell carcinoma with 5-year PFS of 55% (95% CI 33%-91%) and 5-year OS of 65% (95% CI 44%-97%), and Xp11.2 translocation renal cell carcinoma with 5-year PFS of 38% (95% CI 9%-100%) and 5-year OS of 43% (95% CI 10%-100%). The difference in PFS and OS between ccRCC, chromophobe renal cell carcinoma, papillary renal cell carcinoma, and Xp11.2 translocation renal cell carcinoma was statistically significant ( P<0.01). In addition, the multivariate Cox regression analysis revealed that the independent risk factor for PFS in nccRCC patients is the invasion of the renal vein without venous wall involvement ( HR = 8.0, 95% CI 1.8-36.2, P<0.01). Conculsions:Compared to ccRCC, pT 3a nccRCC is more prone to lymph node metastasis. Among them, papillary renal cell carcinoma and Xp11.2 translocation renal cell carcinoma have a poorer prognosis, resulting in an overall lower survival period for pT 3a nccRCC patients. Among different pT 3a characteristics, invasion of the renal vein without invading the vein wall is an independent risk factor for PFS in nccRCC patients.
