[Objective] To systematically evaluate the therapeutic effect of washed red blood cells and white suspended red blood cells on patients with autoimmune hemolytic anemia, and to provide reference for their clinical treatment. [Methods] CNKI, Wanfang, VIP, PubMed, Embase, Cochrane Library and other databases from the establishment of the database to August 2024 were searched, including the randomized controlled trials of washed red blood cells and white suspended red blood cells in the treatment of autoimmune hemolytic anemia that met the requirements. After literature screening, data extraction and quality evaluation, meta-analysis was performed using Review manager 5.3 software and Stata 15.1 software to analyze the therapeutic effect of blood transfusion in the primary outcome, hematological indicators (Hb, Ret, RBC, and TBIL) of the two groups after blood transfusion and the occurrence of adverse blood transfusion reactions. [Results] After screening, 10 literatures meeting the criteria were retrieved, and a total of 753 patients with autoimmune hemolytic anemia were treated with washed red blood cell infusion in the observation group and white suspended red blood cell infusion in the control group. Meta-analysis suggested that there was no significant difference in the therapeutic effect of transfusion between patients who received washed red cells and those received white suspended red cells[SMD=1.16, 95%CI (0.87, 1.54), P>0.05]. The hematological indexes of the two groups after transfusion (Hb [SMD=0.04, 95%CI (-0.14, 0.22), P>0.05]、Ret[SMD=-0.15, 95%CI (-0.34, 0.03), P>0.05]、RBC[SMD=0.08, 95%CI (-0.10, 0.26), P>0.05] and TBIL [SMD=-0.02, 95%CI (-0.18, 0.15), P>0.05]) and the incidence of transfusion adverse reactions[SMD=0.8, 95%CI (0.47, 1.39), P>0.05] were not significantly different. [Conclusion] Based on the current study, the efficacy and safety of infusion of washed red blood cells and white suspended red blood cells are comparable in patients with autoimmune hemolytic anemia. However, considering the simple preparation process of washed red blood cells and the low price, infusion of washed red blood cells is recommended for patients with autoimmune hemolytic anemia.

Objective:Analyze the impact of smoking on the mortality and life expectancy of residents in Tianjin in 2019.Methods:Use mortality case-control study method to collect all cause of death cases of residents in Tianjin in 2019 for analysis. After adjusting for the 5-years-old age group, education level, and marital status, the smoking attributed deaths from different diseases of different genders, smoking attributed deaths in different age groups, and their impact on life expectancy were analyzed.Results:The total number of deaths in 2019 was 75 254, with 42 201 males (56.1%). Among male deaths, 3 215 (9.9%) were attributed to smoking, of which 2 157 (50.2%) lung cancer deaths were attributed to smoking; The risk of lung cancer death among smokers was 3.075 times higher than that of non-smokers (95% CI: 2.812-3.364); Among the 33 053 female deaths (43.9%), 1 396 (5.8%) were caused by smoking, with 744 (29.1%) lung cancer deaths attributed to smoking. The age group with the highest number of deaths attributed to smoking for women was the 75-<80 years old age group, followed by the 70-<75 and 80-<85 years old age groups. The age group with the highest proportion of deaths attributed to smoking for men was the 55-<60 years old age group. In addition, smoking accounts for more than 60% of deaths in the 60-<65, 45-<50, 55-<60, and 65-<70 years old age groups. In 2019, the loss of life expectancy attributed to smoking deaths among all residents in Tianjin was 1.13 years, with a loss of 1.15 years for males and 0.57 years for females. The expected life expectancy excluding deaths caused by smoking was 82.92 years, 80.77 years for males and 84.61 years for females. Conclusions:Smoking remains one of the important risk factors for death among residents. Promoting effective measures to reduce smoking rates is an effective way to increase life expectancy.

Objective:Investigating the efficacy of unilateral adrenalectomy in treatment for primary pigmented nodular adrenocortical disease (PPNAD).Methods:Clinical data of 26 patients with PPNAD treated in our hospital from January 2013 to June 2023 was retrospectively analyzed.There were 11 males and 15 females, with an average age of (19.4±4.7) years. 25 cases presented with typical Cushing's syndrome, and 16 cases were diagnosed with Carney's syndrome. PRKAR1A gene mutation detected in 8 out of 10 cases. CT showed multiple small nodules on bilateral adrenal glands in 14 cases, unilateral small nodules or mild thickening with normal contralateral glands in 8 cases, and no obvious abnormalities in 4 cases. All patients showed autonomous oversecretion of cortisol by endocrine laboratory tests, with a median 24 h-UFC of 408.35 (334.28, 800.78) μg/24 h and decreased level of adrenocorticotropic hormone. All 26 patients underwent laparoscopic unilateral adrenalectomy, with left side adrenalectomy in 8 cases and right side adrenalectomy in 18 cases.Results:The average surgical duration was (85.2±28.7) minutes, with intraoperative blood loss <50 ml in all cases. The median time to drainage tube removal post-operation was 3 (2, 3) days. One patient developed a postoperative pulmonary infection, and 3 patients required postoperative hormone replacement therapy. The median follow-up duration was 64 (31.5, 103.8) months, and all patients showed alleviation of Cushing syndrome clinical manifestations after operations. 19 patients (73.1%) had their 24 h-UFC levels normalized to a median of 42.0 (22.4, 58.3) μg/24 h within 8.5 (5, 46) days post-surgery. 7 patients (26.9%) did not achieve normal 24 h-UFC levels, yet experienced an average reduction of (73.2±10.4)%. 13 patients (50.0%) did not experience recurrence, with a median follow-up of 51 (7, 89.5) months, including two cases without recurrence at 10 years post-surgery. 13 patients showed recurrent increase in postoperative cortisol levels, with a median of 225.6 (188.9, 397.2) μg/24 h. The median time to increased 24 h-UFC post-surgery was 27 (13.5, 50.5) months, with the longest duration reaching 104 months. Among these, 9 cases exhibited clinical signs and symptoms of recurrence, while 4 cases did not. Of the 13 patients with recurrence, 9 underwent contralateral adrenalectomy or subtotal resection, while 4 were observed with follow-up.Conclusions:Unilateral adrenalectomy could be a surgical treatment option for PPNAD. Despite the recurrence in some patients postoperatively, unilateral adrenalectomy could effectively and rapidly reduce cortisol levels in PPNAD patients and alleviate the clinical manifestations of Cushing syndrome.

Objective:To analyze retinal vascular parameters and distribution characteristics in Chinese population via the fully automated quantitative measurement of retinal vascular morphological parameters based on artificial intelligence technology.Methods:A cross-sectional study was performed.A total of 1 842 patients without fundus diseases who visited Beijing Tongren Hospital from January 2011 to December 2021 were included.Standardized questionnaires, blood draws and ophthalmologic examinations of enrolled subjects were conducted.Color fundus photographs centered on the optic disk of one eye of patients were collected, and a deep learning-based semantic segmentation network ResNet101-Unet was used to construct a vascular segmentation model for fully automated quantitative measurement of retinal vascular parameters.The main measurement indexes included retinal vascular branching angle, vascular fractal dimension, average vascular caliber, and average vascular tortuosity.To compare different retinal parameters between sexes, the correlation between the above parameters and ocular factors such as best corrected visual acuity, intraocular pressure, and axial length, as well as systemic factors such as sex, age, hypertension, diabetes mellitus, and cardiovascular disease was analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Beijing Tongren Hospital, Capital Medical University (No.20001220). Written informed consent was obtained from each subject.Results:The model established in this study achieved an accuracy over 0.95 for both vascular and optic disk segmentation.The vascular branching angle, vascular fractal dimension, average vascular caliber, and average vascular tortuosity were (51.023±11.623)°, 1.573(1.542, 1.592), 64.124(60.814, 69.053)μm, (0.001 062±0.000 165)°, respectively.Compared with females, males had larger vascular branching angle, smaller average vascular caliber and smaller vascular tortuosity, and the differences were statistically significant (all at P<0.05). The average vascular caliber increased by 1.142 μm in people with cardiovascular disease compared to people without cardiovascular disease ( B=1.142, P=0.029, 95% CI: 0.116-2.167). The average vascular tortuosity was positively correlated with hypertension ( B=3.053×10 -5, P=0.002, 95% CI: 1.167×10 -5-4.934×10 -5) and alcohol consumption ( B=1.036×10 -5, P=0.014, 95% CI: 0.211×10 -5-1.860×10 -5) and negatively correlated with hyperlipidemia ( B=-2.422×10 -5, P=0.015, 95% CI: -4.382×10 -5-0.462×10 -5). For each 1-mm increase in axial length, there was a decrease of 0.004 in vessel fractal dimension ( B=-0.004, P<0.001, 95% CI: -0.006--0.002), a decrease of 0.266 μm in the average vessel caliber ( B=-0.266, P=0.037, 95% CI: -0.516--0.016), and a decrease of -2.45×10 -5° in the average vessel tortuosity ( B=-2.45×10 -5, P<0.001, 95% CI: -0.313×10 -5--0.177×10 -5). For each 1.0 increase in BCVA, there was an increase of 3.992° in the vascular branch angle ( B=3.992, P=0.004, 95% CI: 1.283-6.702), an increase of 0.090 in vascular fractal dimension ( B=0.090, P<0.001, 95% CI: 0.078-0.102) and a decrease of 14.813 μm in the average vascular diameter ( B=-14.813, P<0.001, 95% CI: -16.474--13.153). Conclusions:A model for retinal vascular segmentation is successfully constructed.Retinal vessel parameters are associated with sex, age, systemic diseases, and ocular factors.

Tuberous sclerosis complex (TSC) is a rare autosomal dominant genetic disease involving multiple organ system. Renal angiomyolipoma (RAML) is a leading cause of death for adult TSC patients. Our study aims at investigating the clinical manifestations of TSC-RAML to enable clinicians to have a better understanding of the disease in Chinese patients.

The"common medicines for various diseases"in the preface of Collective Commentaries on the Classic of Materia Medica has been highly praised by medical practitioners for its unique"disease-medicine"outline and clinical practicality,and has continued to be included and developed in later works on materia medica and prescriptions,laying the foundation for the research and develop-ment of"specialized prescriptions for specialized diseases"and"specialized medicines for specialized diseases".Tao Hongjing used"the root of major diseases"in Shen Nong's Classic of the Materia Medica as the basic framework,referred to the prescriptions and med-icines in Treatise on Cold Damage and Miscellaneous Diseases,and expanded his own and other medical experience to create the"com-mon medicines for various diseases"system,relating and summarizing the representative diseases and main therapeutic effects of medi-cines,and creating a"disease-medicine"outline system.The construction of the"common medicines for various diseases"system has opened up the precedent of"specialized prescriptions for specialized diseases"and"specialized medicines for specialized diseases",providing new prescription ideas for clinical differentiation and treatment.

Objective:To investigate the predictive effect of adjusted Utrecht staging criteria on efficacy of mammalian target of rapamycin (mTOR) inhibitors in patients with tuberous sclerosis-associated renal angiomyolipoma (TSC-AML).Methods:In this study, 39 adult patients with TSC-AML who attended the Peking Union Medical College Hospital from December, 2014 to December, 2020 were retrospectively analyzed, and were divided into 4 groups based on Utrecht staging criteria: Group 1, Utrecht staging ≤ stage 5, all AMLs <5 cm( n=6); Group 2, stage 6 with at least one AML ≥5 cm and normal renal anatomy( n=14); Group 3, stage 6 with at least one AML ≥5 cm and recognizable renal anatomy( n=10); Group 4, stage with at least one AML ≥5 cm and unrecognizable renal anatomy ( n=9). The mean age of patients in the 4 groups were 27.33±7.84, 28.64±12.36, 31.10±5.88 and 29.11±7.15 ( P=0.869). No statistic difference in gender was found among the different groups ( P=0.233). The mean maximum diameters of AML in the four groups were (3.54±0.52)cm, (8.11±2.08)cm, (11.58±4.60)cm and (17.08±3.61)cm, respectively( P<0.01). The mean levels of creatinine were (80.17±16.01)μmol/L, (76.36±18.72)μmol/L, (76.10±27.61)μmol/L and (71.89±18.66)μmol/L in the four groups( P=0.900). The numbers of patients with positive urine protein were 2, 3, 8 and 2 ( P=0.023). All the patients took Everolimus 10mg orally per day for at least 3 months. Differences in maximum AML shrinkage rate, creatinine level, severity of urine protein and microscopic hematuria were compared between the groups. Results:As AML severity increased, the shrinkage rates decreased significantly in turn [Group 1: (76.06±13.16)%, Group 2: (64.92±16.33)%, Group 3: (55.30±20.49)%, Group 4: (43.73±20.61)%, P=0.009]. After treatment, creatinine levels increased in all groups[Group 1: (8.50±7.61)μmol/L, Group 2: (5.71±8.54)μmol/L, Group 3: (7.70±7.18)μmol/L, Group 4: (6.11±7.04)μmol/L], but there was no significant difference among groups (P=0.856). Moreover the increase in urine protein worsened with the degree of severity (Group 1∶3, Group 2∶4, Group 3∶6, Group 4∶9, P=0.014). Conclusions:The adjusted Utrecht staging criteria could predict the maximum AML shrinkage rate and urine protein increase in TSC-AML patients with treatment of mTOR inhibitors.

Objective:To evaluate the effect of tobacco control in different public places after 10 year implementation of Tobacco Control Regulations in Tianjin, investigate the tobacco exposure and tobacco hazard awareness of local population, and provide evidence for the implementation of tobacco control policies and measures.Methods:Data were collected in the tobacco control surveys in Tianjin in 2012 and 2021. On-site observation was used to evaluate the implementation of tobacco control measures in different public places in Tianjin, and face-to-face interview was used to collect the information about passive smoking exposure and tobacco-related knowledge awareness of local residents aged ≥15 years in Tianjin.Results:From 2012 to 2021, the posting rate of smoking free signs in medical institutions was high (100.0%), the posting rate in schools, government offices increased to 100.0%, but posting rate in taxis decreased obviously. The placing rate of tobacco control materials in medical institutions, public transportation waiting places and internet cafes decreased, while the placing rate in other places increased. Except for taxis, the places where people were found to be smoking decreased. The passive smoking exposure in public places and workplaces decreased from 43.2% to 26.6%. The public awareness that smoking can cause stroke increased by 11.3%, but the public awareness rate of smoking causing heart disease decreased and lung cancer by 7.7% and 7.2% respectively. The awareness rate of passive smoking causing heart disease in adults, lung disease in children and lung cancer in adults decreased by 21.8%, 22.1% and 9.1%, respectively.Conclusion:Since the implementation of the Tobacco Control Regulation in Tianjin, the passive smoking exposures have been reduced, but the environment layout of smoking free places, especially the health education about tobacco hazards, needs to be further improved. It is suggested to strengthen the promotion and supervision of tobacco control to create a smoke free environment.

【Objective】 To systematically evaluate the therapeutic efficacy of autologous platelet-rich plasma combined with negative pressure wound therapy on chronic refractory wounds, and to provide reference for clinical treatment. 【Methods】 Randomized controlled trials of autologous platelet-rich plasma combined with negative pressure wound therapy for the treatment of chronic refractory wounds were included in the databases of CNKI, Wan fang, VIP, PubMed, Embase and Cochrane Library from the time of database construction to November 2022. After literature screening, data extraction and quality evaluation, Meta analysis was performed using Stata 15.1 software. 【Results】 After screening, a total of 11 Chinese literatures that met the criteria of this paper were retrieved, involving a total of 359 patients with chronic refractory wounds. The observation group was treated with autologous platelet-rich plasma combined with negative pressure wound therapy, and the control group was treated with negative pressure wound therapy alone. Meta-analysis suggested that compared with negative pressure wound therapy alone, autologous platelet-rich plasma combined with negative pressure wound therapy shortened wound healing time [WMD=-6.08, 95%CI (-7.77, -4.40), P<0.05]. The hospitalization was shortened [WMD=-8.24, 95%CI (-11.55, -4.94), P<0.05], the pain score was decreased [WMD=-1.73, 95%CI (-2.06, -1.40), P<0.05], and the positive rate of bacterial culture on the wound was decreased [RR=0.28, 95%CI(0.16, 0.49), P<0.05], the wound treatment effect was good [RR=1.28, 95%CI(1.17, 1.41), P<0.05]. 【Conclusion】 Based on current studies, compared with the negative pressure wound therapy alone, autologous platelet-rich plasma combined with negative pressure wound therapy can effectively promote the healing of chronic refractory wounds, shorten the hospital stay, reduce pain and infection, and the clinical treatment effect is better.

Objective:To explore the clinical value of 68Ga-pentixafor PET/CT targeting for CXCR4 in the diagnosis and prognosis evaluation of primary aldosteronism (PA). Methods:Retrospective analysis was performed on information of 72 patients diagnosed with PA who received operations according to the results of 68Ga-pentixafor PET/CT in our hospital. There were 37 males and 35 females, with the average age of (48.3±9.5) years old. The average lesion diameter was (1.60 ± 0.54)cm. The preoperative systolic and diastolic blood pressure were (177.3 ± 23.9)mmHg and (107.6 ± 13.2)mmHg, respectively. The average preoperative potassium level was (2.62 ± 0.56)mmol/L. The average aldosterone concentration was (17.98 ± 4.66)ng/dl, and the median plasma renin activity was 0.01 (0.01, 0.09) ng/(ml·h). All patients underwent 68Ga-pentixafor PET/CT examination, which lead to the decision of surgical strategies. For those patients with single lesion, multiple lesions in one side or positive lesion in one side but negative in the opposite side, surgical resection of the positive side lesion or total adrenalectomy was considered. For those patients with bilateral positive lesions, surgical resection of the side with more significant positive lesions or total adrenalectomy was considered. For those with negative multiple lesions, the surgical strategy was designed according to the results of CT examination or AVS. The positive rate of 68Ga-pentixafor PET/CT and its relationship with the clinical characteristics and prognosis of patients were analyzed. Results:The results of 68Ga-pentixafor PET/CT were positive in 62 of 72 patients diagnosed with PA (86.1%), and the median SUVmax value was 11.1 (7.1, 16.2). The SUVmax value was positively correlated with the maximum diameter of adrenal lesion ( r=0.468) and negatively correlated with blood potassium levels ( r=-0.437), while not significantly correlated with other clinical characteristics. The positive rate of adenoma by 68Ga-pentixafor PET/CT was higher than that of nodular hyperplasia [90.5%(57/63) vs. 55.6%(5/9), P=0.018], and the SUVmax value in adenoma was also higher than that in nodular hyperplasia [11.9(7.8, 16.2) vs. 4.3(3.4, 11.3), P=0.022]. 32 cases were cured after operations, and 37 cases were improved. And 3 cases were not cured. The SUVmax value of lesions in the cured patients was higher than that in the improved patients [15.4(8.1, 22.7) vs. 10.1(6.8, 13.3), P=0.013]. Among 59 cases of PA patients with single adrenal lesions, 50 cases represented positive results of 68Ga-pentixafor PET/CT. 23 cases in 50 positive cases were cured and 27 cases were improved after resection of positive lesions. In the 13 PA patients with multiple adrenal lesions who underwent surgery according to the results of 68Ga-pentixafor PET/CT, 12 patients (92.3%) showed postoperative prognosis in line with preoperative expectations. Conclusions:68Ga-pentixafor PET/CT showed high positive rate in the diagnosis of PA, especially for adenoma.The SUVmax value of the adrenal lesion was correlated with the blood potassium level, the size of the lesion and the postoperative prognosis. In addition, 68Ga-pentixafor PET/CT could effectively guide the surgical decision of PA.
