ABSTRACT

Background@#Enterotoxigenic Escherichia coli (ETEC) infection is a primary cause of livestock diarrhea. Therefore, effective vaccines are needed to reduce the incidence of ETEC infection. @*Objectives@#Our study aimed to develop a multivalent ETEC vaccine targeting major virulence factors of ETEC, including enterotoxins and fimbriae. @*Methods@#SLS (STa-LTB-STb) recombinant enterotoxin and fimbriae proteins (F4, F5, F6, F18, and F41) were prepared to develop a multivalent vaccine. A total of 65 mice were immunized subcutaneously by vaccines and phosphate-buffered saline (PBS). The levels of specific immunoglobulin G (IgG) and pro-inflammatory cytokines were determined at 0, 7, 14 and 21 days post-vaccination (dpv). A challenge test with a lethal dose of ETEC was performed, and the survival rate of the mice in each group was recorded. Feces and intestine washes were collected to measure the concentrations of secretory immunoglobulin A (sIgA). @*Results@#Anti-SLS and anti-fimbriae-specific IgG in serums of antigen-vaccinated mice were significantly higher than those of the control group. Immunization with the SLS enterotoxin and multivalent vaccine increased interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) concentrations. Compared to diarrheal symptoms and 100% death of mice in the control group, mice inoculated with the multivalent vaccine showed an 80% survival rate without any symptom of diarrhea, while SLS and fimbriae vaccinated groups showed 60 and 70% survival rates, respectively. @*Conclusions@#Both SLS and fimbriae proteins can serve as vaccine antigens, and the combination of these two antigens can elicit stronger immune responses. The results suggest that the multivalent vaccine can be successfully used for preventing ETEC in important livestock.

ABSTRACT

Objective:To analyze the clinical features of chronic active Epstein-Barr virus infection (CAEBV) in order to reduce the rates of underdiagnosis and misdiagnosis of this disease.Methods:The CAEBV related literatures of PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, WanFang Database and Chongqing VIP since the first literature published (May 1987) until August 29, 2020 were searched. The clinical characteristics, laboratory examinations, outcome and causes of death of CAEBV patients were retrospectively analyzed. Statistical analysis was performed by Mann-Whitney U test, chi-square test or Fisher′s exact probability test. Results:A total of 111 patients aged 22.0 (10.0, 39.0) years were included from 46 articles. There were 64 cases (57.7%) in the age ≥18 years group and 47 cases (42.3%) in the age <18 years group. Fever, splenomegaly, hepatomegaly, and lymph node enlargement were common clinical manifestations, with incidences of 95.5%(106/111), 84.7%(94/111), 57.7%(64/111) and 56.8%(63/111), respectively. The incidences of rash and hepatomegaly in the age ≥18 years group were 3.1%(2/64) and 45.3%(29/64), respectively, which were both lower than those in patients aged <18 years group (27.7%(13/47) and 74.5%(35/47), respectively), while the incidence of abnormal liver biochemical indexes was higher (45.3%(29/64) vs 23.4%(11/47)). The differences were all statistically significant ( χ2=13.957, 9.436 and 5.643, respectively, all P<0.05). Of the 70 patients with follow-up outcomes, 38(54.3%) died and 32(45.7%) survived. The causes of death included gastrointestinal bleeding, severe infection, respiratory failure, liver failure, etc. The incidences of splenomegaly in the death and survival groups were 92.1%(35/38) and 68.8%(22/32), respectively. The difference was statistically significant ( χ2=6.266, P<0.05). Of 21 death and 17 survival cases in the age <18 years group, 15(71.4%) and two cases were combined hemophagocytic lymphohistiocytosis (HLH), respectively, with statistical significance ( χ2=13.527, P<0.01). Of the 90 patients whose HLH-related information was available, 38(42.2%) combined HLH and 52(57.8%) without HLH, with 36.8%(14/38) and 65.4% (34/52) of males, respectively. The difference of gender distribution was statistically significant ( χ2=7.187, P=0.007). The treatment regimens of the 111 CAEBV patients during the course of disease were various, but the detailed information was lacking. Conclusions:The clinical manifestations of CAEBV are diverse. CAEBV can be complicated with fatal complications, lacks of effective treatment, and shows poor prognosis. It is necessary to actively carry out related research to improve the understanding of the disease, and explore effective treatment and reduce mortality.

ABSTRACT

Objective:To study the nutritional risk and nutritional support in patients with liver cancer during perioperative period.Methods:In Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical, the clinical data of 507 liver cancer patients who underwent surgery College from January 2019 to January 2020 were retrospectively analyzed. The perioperative nutrition was assessed by nutritional risk screening 2002 (NRS 2002), ≥3 scores was diagnosed nutritional risk, and the nutritional support was counted.Results:Among 507 patients, 82 cases (16.2%) had nutritional risk. There was no statistical difference in rate of nutritional risk between male and female: 15.3% (58/379) vs. 18.8% (24/128), χ2 = 0.838, P>0.05. There was no statistical difference in rate of nutritional risk between primary liver cancer patients and secondary liver cancer patients: 18.0% (63/350) vs. 12.1% (19/157), χ2 = 2.781, P>0.05. The rate of nutritional risk in ≥ 60 years old patients was significantly higher than that in <60 years old patients: 25.9% (62/239) vs. 7.5% (20/268), and there was statistical difference ( χ2 = 31.819, P<0.01). The age, incidence of dystrophy and rate of nutritional support before surgery in patients with nutritional risk were significantly higher than those in patients without nutritional risk: (65.3 ± 12.7) years old vs. (55.9 ± 8.9) years old, 13.4% (11/82) vs. 0 and 24.4% (20/82) vs. 2.6% (11/425), and there were statistical differences ( P<0.01); there were no statistical differences in sex composition, tumor origin, rate of nutritional support after surgery and albumin between patients with nutritional risk and patients without nutritional risk ( P>0.05). Among 31 nutritional support patients before surgery, parenteral nutrition (PN) was in 1 case, enteral nutrition (EN) was in 30 cases; among 453 nutritional support patients after surgery, PN was in 297 cases, EN was in 27 cases, and PN + EN was in 129 cases. Conclusions:The incidence of nutritional risk in patients with liver cancer during perioperative period is high, and especially elderly patients should pay attention to nutritional support. NRS 2002 is a powerful tool and should be recommended to use at patients with liver cancer, and provide the evidence of nutritional therapy.

ABSTRACT

Chronic hepatitis B (CHB) liver fibrosis is the process of liver tissue damage and repair caused by hepatitis B virus (HBV) infection and may develop into liver cirrhosis in severe cases, and there are still no specific drugs for the treatment of this disease. This article summarizes the main targets involved in the development and progression of CHB liver fibrosis, such as hepatic stellate cell activation, inflammation, and gut-liver axis, as well as the signal transduction pathways associated with fibrosis, and targeting these targets may have a certain anti-fibrogenic effect. At present, anti-HBV therapy combined with or followed by anti-fibrotic therapy can delay or even reverse liver fibrosis/cirrhosis in some patients; however, the reversal of advanced liver fibrosis/cirrhosis still faces great challenges, and there is still no consensus on the timing of combined or sequential therapy. It is believed that identification of therapeutic targets highly associated with CHB liver fibrosis/cirrhosis and combination therapy with compounds targeting multiple pathways associated with liver fibrosis will become the focus of future research.

ABSTRACT

Alzheimer's disease (AD) is currently the most common neurodegenerative disorder characterized by insidious onset and slow progression, which has seriously endangered the physical and mental health of the elderly. It is therefore very important to carry out the early diagnosis and active prevention and treatment. Biomarkers are essential for its diagnosis. Looking for ideal biomarkers is helpful for early identification of this disease. The prevention and treatment of AD with traditional Chinese medicine (TCM) has always been a hot spot in scientific research due to good safety and small side effects. Proteomics is an advanced omics technology that enables the identification and characterization of proteins. Its high-throughput, dynamic, and comprehensive characteristics coincide with the concept of holism emphasized in TCM diagnosis and treatment, which makes proteomics suitable for identifying biomarkers with diagnostic potential, objectifying TCM syndrome differentiation and treatment, and developing new Chinese medicinal prescriptions for precise and targeted treatment. Although the proteomics technology is becoming increasingly mature, it still faces challenges in the diagnosis and treatment of AD. There exist such shortcomings as high heterogeneity and poor reproducibility of protein omics results, requirement for the combination with other advanced omics technologies, and high sequencing cost. In the future, the protein omics technology should be constantly updated and optimized to boost precision medicine, disease prevention, and drug research and development. This paper retrieved related articles from Pubmed, China National Knowledge Infrastructure (CNKI) and reviewed the application of proteomics in the early diagnosis of AD and its prevention and treatment with TCM in recent years, in order to provide reference for the in-depth study of AD diagnosis as well as its prevention and treatment with TCM.

ABSTRACT

Objective:To study the protective effect of polysaccharides from Plantaginis Semen (PSP) against renal injury in rats with membranous nephropathy (MN) and its influence on the gut microbiota to provide a theoretical basis for the further investigation of PSP in the treatment of MN. Method:The MN model was induced by tail vein injection of cationic bovine serum albumin (C-BSA, 3.5 g·L<sup>-1</sup>) in rats with a modeling period of seven weeks. At the 4th week of modeling, the model rats were divided into a model group, a positive drug group (benazepril hydrochloride, 10 mg·kg<sup>-1</sup>·d<sup>-1</sup>), a PSP high-dose group (PSP-H, 800 mg·kg<sup>-1</sup>·d<sup>-1</sup>), a PSP medium-dose group (PSP-M, 400 mg·kg<sup>-1</sup>·d<sup>-1</sup>), and a PSP low-dose group (PSP-L, 200 mg·kg<sup>-1</sup>·d<sup>-1</sup>) according to the random number table, with 10 in each group. Ten healthy rats were assigned to the normal control group. The rats in the normal control group and the control group received an equal amount of physiological saline by gavage, and those in the groups with drug intervention were administered correspondingly,once a day,for consecutive four weeks. The pathological changes of rat kidney and colon tissues were observed by optical microscopy. The enzyme-linked immunosorbent assay (ELISA) was used to detect the content of tumor necrosis factor-<italic>α </italic>(TNF-<italic>α</italic>) and interleukin-1<italic>β </italic>(IL-1<italic>β</italic>) in the serum and colon tissues. The immunohistochemistry (IHC) was used to detect the protein expression of TNF-<italic>α </italic>and IL-1<italic>β </italic>in renal tissues. The 16S rRNA sequencing method was used to investigate the effect of PSP on the gut microbiota in MN rats. Result:Compared with the normal control group, the model group showed enlarged glomeruli, thickened basement membrane, atrophied colonic gland, increased TNF-<italic>α</italic> and IL-1<italic>β</italic> in the serum and colon tissues (<italic>P</italic><0.05), and elevated protein expression of TNF-<italic>α</italic> and IL-1<italic>β </italic>(<italic>P</italic><0.01). Compared with the model group, the positive drug group and the PSP-H group displayed shrunk glomerular capsules, relieved basement membrane thickening, and neatly arranged colonic mucosa in colon tissues, while the PSP-M and PSP-L groups were inferior in improving renal tissues and colon tissues. Additionally, the PSP-H and PSP-M groups showed declining TNF-<italic>α</italic> and IL-1<italic>β</italic> in the serum and colon tissues (<italic>P</italic><0.05) and dwindled protein expression of TNF-<italic>α</italic> and IL-1<italic>β </italic>in the renal tissues (<italic>P</italic><0.01). No significant difference was observed in the PSP-L group. Compared with the normal control group, the model group showed increased abundance of Firmicutes and decreased abundance of Bacteroidetes. After PSP intervention, the abundance of Firmicutes was decreased, while that of Bacteroidetes was increased, and such changes were predominant in the PSP-H group. Conclusion:PSP can effectively alleviate renal injury, reduce the expression of inflammatory factors, regulate the structure of gut microbiota, and improve the damaged intestinal barrier of MN rats.

ABSTRACT

BACKGROUND@#Shenque (CV8) acupoint is located on the navel and has been therapeutically used for more than 2000 years in Traditional Chinese Medicine (TCM). However, clinical research on the underlying therapeutic molecular mechanisms of the CV8 acupoint lags far behind. This study aimed to study the mechanisms of umbilical acupoint therapy by using stem cells.@*METHODS@#The morphological characteristics of CV8 acupoint were detected under a stereomicroscope using hematoxylin and eosin (H&E) staining. Oil Red, Masson, and immunohistochemical staining on multi-layered slices were used to identify the type of cells at the CV8 acupoint. Cell proliferation was measured by a cell counting kit-8 (CCK-8) method. Flow cytometry and immunohistochemistry were used for cell identification. Induced differentiation was used to compare the differentiation of cells derived from CV8 acupoint and non-acupoint somatic stem cells into other cell types, such as osteogenic, adipogenic, and neural stem cell-like cells.@*RESULTS@#Morphological observations showed that adipose tissues at the linea alba of the CV8 acupoint in mice had a mass-like distribution. Immunohistochemical staining confirmed the distribution of stem cell antigen-1 (Sca-1) positive cells in the multi-layered slices of CV8 acupoint tissues. Cells isolated from adipose tissues at the CV8 acupoint exhibited high expression of Sca-1 and CD44 and low expression of CD31 and CD34, and these cells possessed osteogenic, adipogenic, and neurogenic stem cell-like cell differentiation ability. The cell proliferation (day 4: 0.5138 ± 0.0111 vs. 0.4107 ± 0.0180, t = 8.447, P = 0.0011; day 5: 0.6890 ± 0.0070 vs. 0.5520 ± 0.0118, t = 17.310, P 100 μm: 2.6000 ± 0.5477 vs. 0.8000 ± 0.8367, t = 4.025, P = 0.0038) were significantly enhanced in somatic stem cells derived from the CV8 acupoint compared to somatic stem cells from the groin non-acupoint. However, cells possessed significantly weaker osteogenicity ([2.697 ± 0.627]% vs. [7.254 ± 0.958]%, t = 6.893, P = 0.0023) in the CV8 acupoint group.@*CONCLUSIONS@#Our study showed that CV8 acupoint was rich with adipose tissues that contained abundant somatic stem cells. The biological examination of somatic stem cells derived from the CV8 acupoint provided novel insights for future research on the mechanisms of umbilical therapy.

ABSTRACT

Objective:To assess the safety and efficacy of riboflavin/ultraviolet-A-induced accelerated epithelium-off corneal collagen cross-linking (CXL) for teenagers with keratoconus.Methods:In this case series study, 25 eyes of 18 patients with primary keratoconus who underwent riboflavin/ultraviolet-A-induced accelerated epithelium-off CXL in Zhengzhou Second People's Hospital from January 2017 to February 2018 were included, and the average age of patients was (14.4±1.3) years.The uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), spherical equivalent (SE), maximum keratometry reading (K max), thinnest corneal thickness (TCT), posterior corneal elevation (PCE) and endothelial cell density (ECD) were measured before and after CXL.The patients were followed up for one year.The complications and adverse reactions were recorded.The study adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Zhengzhou Second People's Hospital (No.KY2017002). Written informed consent was obtained from each patient and their guardian prior to the surgery. Results:The mean UCVA (LogMAR) was 0.96±0.35 at baseline, which was significantly improved to 0.84±0.33 at 1 year postoperatively ( t=-5.765, P<0.01). The mean BCVA (LogMAR) was 0.45±0.22 preoperatively, which was significantly improved to 0.34±0.26 at 1 year postoperatively ( t=-4.843, P<0.01). The mean SE was (8.66±5.11)D at baseline, which was significantly higher than (8.07±5.21)D at 1 year postoperatively ( t=-3.253, P=0.003). The K max was reduced from (58.58±9.07)D preoperatively to (56.25±9.98)D at 1 year postoperatively, with significant difference between the two time points ( t=-4.357, P<0.01). The K max was reduced more than 1 D in 17 eyes (68%), was stable in 6 eyes(24%), and was increased more than 1 D in 2 eyes (8%). The TCT was reduced from (485.0±32.5)μm at baseline to (475.3±35.5)μm at 1 year postoperatively, with significant difference between the two time points ( t=-4.266, P<0.01). The differences of PCE and ECD between preoperative and postoperative 1 year were not statistically significant ( t=1.023, P=0.316; t=-1.424, P=0.167). There was one eye suffering peripheral sterile corneal infiltrate 2 days postoperatively, and favorable prognosis was achieved after the topical steroids application.No complication was encountered in other subjects. Conclusions:Riboflavin/ultraviolet-A-induced accelerated epithelium-off CXL is safe and effective in teenagers with keratoconus during the 1-year follow-up.The long-term effects need further observation.

ABSTRACT

@#Objective    To analyze the feasibility of using triangular-sail technique that allows intermittent two-lung ventilation during minimally invasive coronary artery bypass grafting (MICS CABG). Methods    The clinical data of 207 patients with MICS CABG in our cardiac center from January 2019 to November 2020 were retrospectively analyzed. These patients were divided into two groups. A group OLV included 111 patients who underwent one-lung ventilation during surgery, while a group TLV included 96 patients who underwent intermittent two-lung ventilation. The triangular-sail technique was used in the group TLV. This simple technique isolated the operative field from lung lobes with the traction of pericardial adipose tissue. The preoperative data and perioperative clinical data of the two groups were compared and analyzed. Results    There was no statistical difference in basic preoperative data between the two groups. The operation time in the OLV group was shorter than that in the TLV group (296.7±57.3 min vs. 334.1±87.0 min, P=0.000), and the duration of postoperative mechanical ventilation and ICU stay were not statistically different between the two groups. There was also no statistical difference in the incidence of pneumothorax or atelectasis between the two groups. Conclusion    The triangular-sail technique is simple and easy to implement. The technique allows intermittent two-lung ventilation during MICS CABG procedure.

ABSTRACT

BACKGROUND@#Hepatitis B core-related antigen (HBcrAg) is a promising disease-monitoring marker for chronic hepatitis B (CHB). We investigated correlations between HBcrAg with antiviral efficacy and virological and histological variables.@*METHODS@#One hundred and forty-five CHB patients from the mainland of China between August 2013 and September 2016 who underwent liver biopsy received entecavir therapy and had paired liver biopsy at 78 weeks. We analyzed correlations between HBcrAg and virological and histological variables in hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients. We also explored the predictors of HBeAg loss after 78 weeks of antiviral therapy. Pearson correlation analysis and logistic forward stepwise regression were the main statistic methods.@*RESULTS@#HBeAg-positive patients (n = 93) had higher baseline HBcrAg (median 7.4 vs. 5.3 log10 U/mL P < 0.001) and greater HBcrAg declines (median 1.6 vs. 0.9 log10 U/mL P = 0.007) than HBeAg-negative patients after 78 weeks of therapy. At baseline, HBcrAg correlated with hepatitis B virus (HBV) DNA in both HBeAg-positive (r = 0.641, P < 0.001) and -negative patients (r = 0.616, P < 0.001), with hepatitis B surface antigen (HBsAg) in HBeAg-positive patients (r = 0.495, P < 0.001), but not with anti-hepatitis B virus core antibody (anti-HBc). Weak correlations existed between HBcrAg, histology activity index (HAI; r = 0.232, P = 0.025), and Ishak fibrosis score (r = -0.292, P = 0.005) in HBeAg-positive patients. At 78 weeks, significant correlations existed only between HBcrAg and anti-HBc in HBeAg-positive (r = -0.263, P = 0.014) and HBeAg-negative patients (r = -0.291, P = 0.045). Decreased HBcrAg significantly correlated with reduced HBV DNA (r = 0.366, P = 0.001; r = 0.626, P < 0.001) and HBsAg (r = 0.526, P = 0.001; r = 0.289, P = 0.044) in HBeAg-positive and -negative patients, respectively, and with reduced HAI in HBeAg-positive patients (r = 0.329, P = 0.001). Patients with HBeAg loss (n = 29) showed a larger reduction in HBcrAg than those without (median 2.3 vs. 1.3 log10 U/mL, P = 0.001). In multivariate analysis, decreased HBcrAg was an independent predictor of HBeAg loss (P = 0.005).@*CONCLUSIONS@#HBcrAg reflects viral replication and protein production. Decreased HBcrAg could predict HBeAg loss after antiviral therapy.@*TRIAL REGISTRATION@#Clinical Trials.gov: NCT01962155; https://www.clinicaltrials.gov/ct2/show/NCT01962155?term=NCT01962155&draw=2&rank=1.

ABSTRACT

Objective@#To evaluate the effects of overweight and obesity intervention in the health-promoting school model and to provide reference for effective prevention and control of overweight and obesityin middle Schools.@*Methods@#Using stratified cluster random sampling, 10 middle schools in Sanmenxia City were randomly divided into intervention group and control group. In the intervention group and the control group, one middle school and one high school were randomly selected. The students from the two classes randomly selected in the first and second grades in the four schools that were selected, the questionnaire survey and medical examination was conducted before and after the intervention to evaluate the intervention effect.@*Results@#After intervention, the ratio of overweight and obesity of the intervention group decreased from 22.70% before intervention to 17.45%, statistical significance(χ 2=4.11, P<0.05), and the ratio of overweight and obesity of the control group increased from 22.39% before intervention to 22.91%, no significant difference(P>0.05). After the intervention, the response rates of limiting red meat, fried food and sugarsweetened beverages were all higher than those before the intervention, the differences were statistically significant (χ 2=125.73, 10.69, 208.55, 170.66, 50.01, P<0.01).@*Conclusion@#The comprehensive intervention measures of overweight and obesity in the model of health promotion school can encourage students to develop healthy behaviors and effectively prevent and control middle school students from overweight and obesity, and it is easy to form a long-term intervention mechanism.

ABSTRACT

Purpose@#The evidence of adherence to cancer prevention guidelines and endometrial cancer (EC) risk has been limited and controversial. This study summarizes and quantifies the relationship between adherence to cancer prevention guidelines and EC risk. @*Materials and Methods@#The online databases PubMed, Web of Science, and EMBASE were searched for relevant publications up to June 2, 2020. This study had been registered at PROSPERO. The registration number is CRD42020149966. Study quality evaluation was performed based on the Newcastle-Ottawa Scale. The I2 statistic was used to estimate heterogeneity among studies. Egger’s and Begg’s tests assessed potential publication bias. Summary hazard ratios (HRs) and 95% confidence intervals (CIs) for the relationship between adherence to cancer prevention guidelines score was assigned to participants by summarizing individual scores for each lifestyle-related factor. The scores ranged from least healthy (0) to most healthy (20) and the EC risk was calculated using a randomeffects model. @*Results@#Five prospective studies (four cohort studies and one case‑cohort study) consisted of 4,470 EC cases, where 597,047 participants were included. Four studies had a low bias risk and one study had a high bias risk. Summary EC HR for the highest vs. lowest score of adherence to cancer prevention guidelines was 0.54 (95% CI, 0.40 to 0.73) and had a high heterogeneity (I2=86.1%). For the dose-response analysis, an increment of 1 significantly reduced the risk of EC by 6%. No significant publication bias was detected. @*Conclusion@#This study suggested that adherence to cancer prevention guidelines was negatively related to EC risk.

ABSTRACT

Objective@#To investigate bone mineral density of college students with masked obesity, and to provide theoretical basis for bone density improvement and osteoporosis prevention in college students.@*Methods@#Participants were enrolled from universities and colleges. A total of 518 low-weight or normal-weight students were included and were classified according to the criteria of masked obesity, dual-energy X-ray test was used to detect the percentage of body fat and bone mineral density of college students in each group. The differences in bone mineral density between masked obesity and non-masked obesity groups of different genders were compared, and the correlation between body mass index, body fat percentage and bone mineral density was analyzed.@*Results@#Among the low-weight male college students, the whole body bone mineral density, t-value and Z-value of masked obesity group were lower than those of the nonmasked obesity group [(1.82±0.04,2.01±0.22)g/cm 2; (-1.10±0.24,-0.02±0.15); (-0.94±0.64,-0.01±0.43)(P<0.01)]. Among low-weight male college students, bone mineral density of the upper limbs, thighs, ribs, and pelvis of the masked obesity group was lower than that of the non-masked obesity group. Among low-weight female college students, body bone mineral density of masked obesity group was lower than that of the non-masked obesity group [(1.13±0.48,1.31±0.29)g/cm 2; (P<0.05)]. Among low-weight female college students, bone mineral density of head, upper limbs, thighs, and trunk of masked obesity group was lower than that of the nonmasked obesity group. In male college students, body mass index was positively correlated with bone mineral density, T-value and Z-value (r=0.69, 0.68, 0.61, P<0.01) while body fat percentage was negatively correlated with bone mineral density, T-value and Z-value (r=-0.52, -0.51, -0.49, P<0.01). In female college students, body mass index was positively correlated with T-value and Z-value (r=0.46, 0.26, P<0.01), and body fat percentage was negatively correlated with T-value and Z-value (r=-0.22, -0.23, P<0.01).@*Conclusion@#Compared with normal-weight college students, depletion of bone mineral density among masked obesity students is observed. It is of great significance to pay attention to bone mineral density of college students with masked obesity and implement intervention to prevent osteoporosis timely.

ABSTRACT

@#Objective    To investigate the safety and effectiveness of the multi-artery graf tstrategy for coronary bypass (MICS-CABG) with small incision in the left chest, and to provide experience for the promotion of this technique. Methods    The clinical data of 64 patients with MICS-CABG in Department of Cardiac Surgery of Peking University Third Hospital from December 2015 to November 2019 were retrospectively analyzed. There were 54 males and 10 females, aged 36-77 (61.1±8.7) years. The left lateral thoracic incision (5-8 cm) was made through the 5th intercostal incision, and the operation was performed under off-pump CABG. With the help of the chest wall suspension device and the heart fixator, the proximal anastomosis of the ascending aorta, anastomosis of the target vessels of the left anterior descending (LAD), left circumflex (LCX) and right coronary artery (RCA) systems were completed. The number of grafts was 2-4 (2.3±0.5) including 2 grafts in 45 patients, 3 grafts in 17 patients and 4 grafts in 2 patients. Three patients were treated with percutaneous intervention (PCI) hybridization and 62 patients were treated with total artery bypass graft. Coronary angiography was performed within 7 days after the operation to evaluate the graft patency rate. The incidence of major adverse cardiac and cerebrovascular events (MACCE) was recorded in the follow-up. The MACCE rate was calculated by Kaplan-Meier method. Results    None of the patients was transferred to thoracotomy and no intra-aortic balloon counterpulsation (IABP) or extracorporeal membrane oxygenation (ECMO) was used during the operation.  Incision infection was in 1 patient and reoperation in 2 patients (all were postoperative hemorrhage). Within 30 days after surgery, MACCE occurred in 1 patient, including 1 patient of non-fatal myocardial infarction. The overall patency rate of angiography bypass was 96.2%, and the patency rate of anterior descending branch bypass was 98.2%. Follow-up was performed from 12 to 60 months (median follow-up time was 28 months). The loss rate was 7.8% (5/64). The incidence of MACCE was 84.9% (95%CI 79.5%-90.3%). Conclusion    The MICS-CABG can achieve completed re-vascularization and totally artery-CABG and the short-term and medium-term clinical results of the operation are good.
