Diabetes, hypertension, and dyslipidemia, collectively referred to the " Three Highs, " represent increasingly prevalent metabolic risk factors in China. Many individuals experience all three conditions concurrently, significantly heightening the risk of cardiovascular disease and mortality. Although the National Metabolic Management Center(MMC) has been established for over eight years and has its unique features, the awareness, treatment, and control rates of these diseases in China remain low, and the efficiency of community management is insufficient. According to the previous two editions of management guidelines and the most recent domestic and international diagnostic and treatment guidelines, this paper conducts an in-depth analysis of the operational experience and management strategies of the MMC. Its aim is to improve the efficiency of grassroots MMC mode management for " Three Highs" patients and ensure that patients receive more standardized management.

Objective:To construct dual-targeting(CD38 and CD138)chimeric antigen receptor(CAR)gene-modified T cells(CD38/CD138 CAR-T cells)and explore their in vitro cytotoxicity against multiple myeloma(MM)cells.Methods:Based on the high expression of CD38 and CD138 antigens in MM cells,CD38 CAR-T cells and CD138 CAR-T cells targeting CD38 and CD138 respectively,and CD38/CD138 dual-targeted CAR-T cells targeting both CD38 and CD138 were constructed using CAR-T cell technology.The experimental groups included untreated T cells,CD38 CAR-T,CD138 CAR-T,and CD38/CD138 CAR-T cells.The phenotype of CAR-T cells was detected by flow cytometry.The cytotoxicity of various CAR-T cells against MM cells(RPMI8226 and U266)was assessed using the LDH release assay.Results:Three types of CAR-T cells,CD38 CAR-T,CD138 CAR-T,and CD38/CD138 CAR-T cells,were successfully constructed.The CD38/CD138 CAR-T cells tended to differentiate into a memory phenotype,expressing higher levels of proliferation marker(CD25),activation marker(CD27),and lower levels of exhaustion markers(PD-1,CTLA-4,TIM-3)(all P<0.001).Moreover,CD38/CD138 CAR-T cells were less prone to exhaustion and senescence,and expressed lower levels of r-H2AX,p-p53,p21,and p16 proteins(all P<0.01).Under different effector-to-target cell ratios,CD38/CD138 CAR-T cells exhibited stronger cytotoxic effects against RPMI8226 and U266 cells compared to CD38 CAR-T and CD138 CAR-T cells(all P<0.001).Conclusion:CD38/CD138 CAR-T cells targeting both CD38 and CD138 demonstrate an optimal phenotype and enhanced anti-tumor activity in vitro,offering promising potential for immunotherapy in multiple myeloma.

Background: Gastric mucosal atrophy and intestinal metaplasia (IM) are precancerous conditions of gastric cancer. Although Moluodan has been used in the treatment of chronic atrophic gastritis (CAG), there is little study on efficacy evaluation of Moluodan based on pathological stages. Aims: To assess the efficacy of Moluodan on reversal of gastric mucosal atrophy and IM based on OLGA and OLGIM staging systems, and to analyze the related factors. Methods: A total of 104 patients with CAG and IM from October 2019 to January 2022 at Xijing Hospital of Air Force Medical University were enrolled retrospectively in this study. All the patients received Moluodan treatment (one bag each time, three times daily) for 6 months. Changes of OLGA and OLGIM stages before and after treatment, and the related factors affecting the efficacy were analyzed. Results: After treatment with Moluodan for 6 months, the reversal rates for gastric mucosal atrophy and IM were 47.1% (49/104) and 51.0% (53/104), respectively, and the overall efficacy was 65.4% (68/104). There were 49.3% (34/69) and 52.4% (22/42) of patients with higher OLGA and OLGIM stages (III-) reversed to lower stages (0-Ⅱ), respectively. In addition, patients with OLGA and OLGIM stage III- showed a higher reversal rate than those with stage -Ⅱ (all P<0.01). No correlations were found between the demographic data, life and dietary styles, family history of gastric cancer, operation history, comorbidities, severity of mucosal inflammation and the efficacy of Moluodan (all P>0.05). Conclusions: Moluodan could reverse gastric mucosal atrophy and IM effectively in patients with CAG, which suggests that Moluodan has good potential in prevention of gastric cancer.

Objective:To explore the correlation between intraoperative cooling temperature and postoperative neurological prognosis in aortic arch surgery.Methods:We observed and collected data from 118 patients who underwent open arch replacement surgery by a single surgeon with mild-to-moderate hypothermic circulatory arrest, from January 2017 to December 2020, in Beijing Anzhen Hospital. According to the bladder temperature during the circulation arrest, 118 patients were divided into 3 groups: T1 group[n=39, (25.58±0.64)℃]; T2 group[n=39, (28.21±0.77)℃]; T3 group[n=40, (30.95±0.97)℃]. Clinical data and operative data were analyzed to assess difference between these 3 groups. Analyze the risk factors of postoperative neurological complications, and explore further the correlation between intraoperative core temperature and postoperative neurological prognosis.Results:Among the 118 patients, the average operation, cardiopulmonary bypass (CPB), block, circulatory arrest, and selective cerebral perfusion (SCP) time were 6.64 h, 188.5 min, 104.19 min, 23.93 min, 28.81 min, respectively. The in-hospital death occurred in 8 patients(6.78%), and permanent neurological dysfunction (PND) in 13 patients(11.02%), transient neurological dysfunction (TND) in 25 patients(21.19%). There was no significant difference in the deaths among the three groups. The incidence of TND and PND in the T3 group was significantly reduced ( P=0.042; P=0.045). In addition, the volume of drainage during the first 24 h and the incidence of re-exploration for bleeding had a relatively obvious decreasing trend ( P=0.005; P=0.012). Through multiple regression analysis, under the adjusted model, the core temperature was independently correlated with the incidence of postoperative PND ( OR=0.51; 95% CI: 0.27-0.97; P=0.0389); in group comparison, the relatively higher core temperature was an independent protective factor for postoperative PND ( OR=0.04; 95% CI: 0.00-0.91; P=0.0434). Conclusion:Our research had preliminary proved that in the open arch replacement surgery, mild hypothermia can reduce the incidence of some complications of deep hypothermia, at the same time improve the prognosis of the neurological prognosis, reduce the incidence of postoperative PND.

Objective:To investigate the thyroid volume of adults in Lanzhou City, and analyze its influencing factors.Methods:In June 2016, according to the principle of multi-stage stratified cluster sampling, Han residents aged 18 and above in Chengguan, Xigu and Qilihe districts of Lanzhou City who had lived there for more than 5 years were selected as research subjects, and a portable B-ultrasound machine was used for thyroid examination. Morning urine samples of the subjects were collected to test urinary iodine; fasting venous blood samples of the subjects were collected to test serum thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), anti-thyroglobulin antibody (TgAb), blood lipids [triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL)] and blood uric acid (Ua) levels. At the same time, body indexes systolic blood pressure (SP), diastolic blood pressure (DP), waist circumference, height and weight were measured, and the body mass index (BMI) was calculated. Multiple linear regression was used to analyze the influencing factors of thyroid volume.Results:A total of 1 009 subjects were included, aged (43.50 ± 15.16) years, and the thyroid volume was (8.74 ± 3.39) ml. Among them, 534 males had a thyroid volume of (9.46 ± 3.43) ml; 475 females had a thyroid volume of (7.93 ± 3.15) ml, the thyroid volume of males was larger than that of females ( t = 7.36, P < 0.01). Thyroid volume was positively correlated with age, height, weight, BMI, SP, waist circumference, LDL, Ua and TgAb ( r = 0.07, 0.23, 0.33, 0.27, 0.10, 0.27, 0.10, 0.08, 0.07, P < 0.05), and it was negatively correlated with thyroid nodules, TPOAb, TSH and urinary iodine ( r = - 0.16, - 0.07, - 0.10, - 0.08, P < 0.05). After multiple linear regression analysis, TSH, TPOAb, TgAb and thyroid nodules were included in the regression equation, and the standardized B values were - 0.135, - 0.065, 0.123 and - 0.197, respectively. Conclusions:The thyroid volume of males is larger than that of females in Lanzhou City. TSH, TPOAb, TgAb and thyroid nodules are influencing factors of thyroid volume.

Aromatase deficiency (AD) is a rare autosomal recessive genetic disease caused by loss-of-function mutations in aromatase gene (CYP19A1), leading to congenital estrogen deficiency syndrome. Both mothers of AD patients during pregnancy and female AD fetus show virilization, while male patients are usually diagnosed in adulthood due to continued height increase and metabolic abnormalities. In 2019, a patient with AD was admitted in the Second Xiangya Hospital. The patient was a 37-year-old adult male who continued to grow linearly after adulthood. His estradiol was below the measurable line, the follicle-stimulating hormone (FSH) increased, bone age delayed, epiphysis unfused, and the bone mass reduced. CYP19A1 gene detection showed that c.1093C>T, p.R365W was homozygous mutation. This disease is rare in clinic. Clinicians need to raise awareness of the disease for early diagnosis and treatment to improve the long-term prognosis of patients.

Objective:To investigate the detection rate and related factors of thyroid nodules in people with abnormal lipid metabolism.Methods:From September 4, 2016 to February 1, 2017, community residents living in Lanzhou City, Longnan City, Dingxi City and Linxia City of Gansu Province for more than 5 years were selected as the respondents. General data were recorded, venous blood was collected, blood lipid related biochemical indexes were detected, and thyroid ultrasound was performed. By comparing the general data and biochemical indexes, the detection of abnormal lipid metabolism and thyroid nodules were analyzed, and the risk factors of thyroid nodules in people with abnormal lipid metabolism were analyzed by logistic regression.Results:Two thousand and fifty-nine residents were included in this study (1 049 males and 1 010 females). The total detection rate of thyroid nodules was 23.17% (477/2 059). The detection rate of thyroid nodules in people with abnormal lipid metabolism [34.16%(151/442)] was significantly higher than that in people with normal lipid metabolism [20.16% (326/1 617) , P < 0.01], and the detection rate of thyroid nodules of women [43.37% (85/196) ] was higher than that of men [26.83% (66/246) , P < 0.01]. Among the people with abnormal lipid metabolism, the highest detection rate of thyroid nodules was in mixed hyperlipidemia [57.14% (16/28)], followed by hypertriglyceridemia [34.59% (92/266)]. The detection rates of thyroid nodules in the groups with elevated total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels [35.16% (32/91), 34.85% (23/66)] were higher than those in the marginal elevated group [27.04%(86/318), 30.42% (73/240)] and the normal groups [21.76% (359/1 650), 21.73% (381/1 753), P < 0.05]. The results of logistic regression analysis showed that the risk factors of thyroid nodules in people with abnormal lipid metabolism were increased age, elevated fasting blood glucose (FPG), elevated blood glucose 2 hours (2 h PG) after oral glucose tolerance test (OGTT) load and elevated glycosylated hemoglobin [HbA1c, odds ratio ( OR)=1.065, 1.387, 1.866, 1.384, P < 0.05]. Conclusions:The prevalence of TN is higher in populations with abnormal lipid metabolism. The control of blood sugar and blood lipid levels may play a role in the prevention of thyroid nodules.

The traditional view is that breast reconstruction is not an option for day surgery center. As a result, few hospitals in the world conduct this operation in day surgery center. Endoscopic breast reconstruction with liposuction and robot-assisted breast reconstruction are minimally invasive surgeries for breast cancer patients, but they cannot be carried out in the day surgery center due to long operation time. The novel endoscopic-assisted immediate implant-based breast reconstruction after nipple sparing mastectomy through a single axillary incision for breast cancer patients has been successfully conducted in the day surgery center in our hospital due to short operation time and small trauma. Standardized management of the complete process from the patient selection to follow-up after discharge brings rapid recovery and few complications. At the same time, the development of endoscopic surgery makes the breast almost scarless and improves aesthetic results. Therefore, the mode of endoscopic-assisted reconstruction in the day surgery center of our hospital is expected to be popularized in the whole country.

Objective:To explore the application of cannulating the ischemic femoral and right axillary artery in Sun’s procedure for acute type A aortic dissection with lower extremity ischemia.Methods:Twelve patients of acute Stanford type A aortic dissection complicated by lower extremity ischemia were analyzed retrospectively between July 2017 and May 2019, and the right axillary and ischemic femoral artery were used for cardiopulmonary bypass. All the 12 patients were male and categorized as the complicated Stanford type A aortic dissection. The mean age was(48.4±8.4)years, and the median time from symptom onset to emergency operation was 24.00(18.50, 43.25)hours. Eleven patients presented with unilateral extremity ischemia, while bilateral extremity ischemia occurred in one. The prosthetic vessel, with a diameter of 8 mm, was anastomosed to the ischemic femoral artery via an end-to-side way. Both the right axillary artery and the prosthetic vessel were cannulated for CPB. For the proximal dissection in this cohort of patients, we performed Bentall procedure in 5 cases, ascending aortic replacement in 3, and the aortic valve commissure reconstruction with ascending aortic replacement in 4. Total arch replacement with stented elephant trunk implantation were carried out for arch and descending aortic lesion in 12 cases.Results:Early mortality was 8.3%(1/12). The time of CPB, aortic clamp, circulatory arrest, and selective cerebral perfusion averaged(204.6±26.3) min, (114.6±16.6) min, (23.4±8.5) min, and(33.5±11.0) min, respectively. Five patients underwent concomitant bypass procedures, including: ascending aorta-bilateral femoral artery bypass in 1, ascending aorta-right femoral artery bypass in 3, ascending aorta-left femoral artery bypass in 1. Acute renal failure with continuous renal replacement therapy occurred in 4 cases, re-thoratomy for hemaostsis in 1, and re-intubation in 1. One patient developed osteofascial compartment syndrome after aortic repair, and consequent left lower extremity compartment fasciotomy was performed. The mean follow-up time was(17.2±7.6)months, and no aortic-related adverse event was detected during follow up.Conclusion:To acute Stanford type A aortic dissection with lower extremity ischemia, cannulating the ischemic femoral and right axillary artery in Sun’s procedure were associated with lower perioperative mortality and better prognosis.
