Lung Cancer Prevalence among Staff in a Cancer Hospital / 中山大学学报(医学科学版)

ObjectiveTo investigate the prevalence of lung cancer among medical staff in a hospital and promote the level of cancer prevention and treatment. MethodsThe annual physical examination data， follow-up pathology and survival data from 2009 to 2021 in a tertiary cancer hospital were collected and then compared with data of lung cancer in China from the global burden of disease database （GBD database）. ResultsThe age-standardized prevalence of lung cancer have been continuously increasing in both populations in recent years. The age-standardized prevalence of lung cancer among medical staff was higher than that in Chinese population， but the age-standardized mortality was lower. The Average Annual Percent Change （AAPC） of lung cancer prevalence among staff was higher than that in Chinese population （13.0% vs. 4.1%）， indicating a higher growth rate. The proportion of newly diagnosed early-stage lung cancer in 2014-2021 was significantly higher than that before adding plain chest CT scan in routine physical examination （2009-2013）， suggesting the benefit of chest CT scan for early screening of lung cancer. ConclusionThe prevalence and growth rate of lung cancer among the staff were higher than those in Chinese population， but the mortality was lower. Plain chest CT scan is essential for early screening and treatment of lung cancer.

A Retrospective Study on the Efficacy and Safety of Idarubicin Combined with High-Dose Cytarabine Consolidation in Patients with Acute Myeloid Leukemia over 60 Years of Age in First Remission / 中国实验血液学杂志

OBJECTIVE@#To evaluate the efficacy and safety of idarubicin combined with high-dose cytarabine as a post-remission therapy for elderly patients with acute myeloid leukemia (AML).@*METHODS@#From November 2017 to June 2021, 24 AML patients aged ≥60 years who were in complete remission for the first time were enrolled in consolidation chemotherapy with idarubicin (10 mg/m2 intravenously once for day 1) combined with high-dose cytarabine (1.5 g/m2 intravenously over 3 hours every 12 hours for day 1-3), and the efficacy and safety were observed.@*RESULTS@#Among the 24 patients, there were 12 males and 12 females, the median age was 65 (60-78) years old, and the median follow-up time was 23.3 (2-42.7) months. By the end of the follow-up, 15 patients relapsed and 11 patients died. The median disease-free survival (DFS) was 9 months and there were 3 cases of 2-year DFS. The median overall survival (OS) was 16.2 months, and there were 4 cases of 2-year OS. In terms of safety, 6 patients had grade 1-2 non-hematological adverse reactions, 12 patients had grade 3-4 hematological adverse reactions, and a total of 6 patients developed infection after consolidation chemotherapy. Multivariate analysis showed that two induction cycles and high-risk cytogenetic abnormalities were the adverse factors of DFS and OS in elderly patients with AML in this study.@*CONCLUSION@#For AML patients ≥60 years old in first complete remission, idarubicin combined with high-dose cytarabine as post-remission therapy has a better safety, but compared with other regimens does not improve the prognosis of elderly patients, which needs further exploration.

Incidence of extrauterine growth retardation and its risk factors in very preterm infants during hospitalization: a multicenter prospective study / 中国当代儿科杂志

OBJECTIVES@#To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China.@*METHODS@#A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined.@*RESULTS@#The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05).@*CONCLUSIONS@#It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

Clinical treatment outcomes and their changes in extremely preterm twins: a multicenter retrospective study in Guangdong Province, China / 中国当代儿科杂志

OBJECTIVES@#To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.@*METHODS@#A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.@*RESULTS@#Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).@*CONCLUSIONS@#There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Prevalence of late-onset hypogonadism among middle-aged and elderly males in China: results from a national survey / 亚洲男科学杂志(英文版)

This study aimed to propose an operational definition of late-onset hypogonadism (LOH) that incorporates both clinical symptoms and serum testosterone measurements to evaluate the prevalence of LOH in aging males in China. A population-based sample of 6296 men aged 40 years-79 years old was enrolled from six representative provinces in China. Serum total testosterone (TT), sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) were measured and free testosterone (cFT) was calculated. The Aging Males' Symptoms (AMS) scale was used to evaluate the LOH symptoms. Finally, 5078 men were included in this analysis. The TT levels did not decrease with age (P = 0.59), and had no relationship with AMS symptoms (P = 0.87 for AMS total score, P = 0.74 for ≥ 3 sexual symptoms). The cFT levels decreased significantly with age (P < 0.01) and showed a negative association with the presence of ≥ 3 sexual symptoms (P = 0.03). The overall estimated prevalence of LOH was 7.8% (395/5078) if a cFT level <210 pmol l

Inverted U-Shaped Associations between Glycemic Indices and Serum Uric Acid Levels in the General Chinese Population: Findings from the China Cardiometabolic Disease and Cancer Cohort (4C) Study / 生物医学与环境科学（英文）

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

The Positive Association between Subclinical Hypothyroidism and Newly-Diagnosed Hypertension Is More Explicit in Female Individuals Younger than 65

Background@#Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension. @*Methods@#Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017. @*Results@#The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years. @*Conclusion@#The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.

Comparative analysis of pharmacokinetics and intestinal absorption of six alkaloids between Sanmiao Pills and Simiao Pills in rats / 中国中药杂志

The present study investigated the differences in pharmacokinetics and intestinal absorption of six alkaloids in Sanmiao Pills and Simiao Pills in rats and explored the different efficacies of the two formulae. After oral administration of Sanmiao Pills and Simiao Pills in rats, blood samples were collected at different time points. Samples were prepared for the determination of six alkaloids in plasma by UPLC-MS/MS. The chromatography was performed on an ACE Excel 3 C_(18 )column with acetonitrile-0.1% formic acid in water as the mobile phase for gradient elution. Analytes were detected in the positive ion mode. Plasma concentrations and pharmacokinetic parameters were calculated. Intestinal absorption of alkaloids was investigated by single-pass intestinal perfusion and absorption parameters of ingredients were calculated. The results showed that the UPLC-MS/MS method for simultaneous determination of concentrations of six alkaloids in plasma was developed and validated by methodological investigations, such as specificity, calibration curves, precision, accuracy, recovery, matrix effect, and stability. The results of the pharmacokinetic assay revealed that C_(max) and AUC values of phellodendrine, berberine, magnoflorine, berberrubine, and jatrorrhizine in Simiao Pills were significantly increased, and CL/F values were reduced as compared with those in Sanmiao Pills, which indicated the increase in plasma concentrations of alkaloids. The intestinal absorption parameters K_(a )and P_(eff) values of phellodendrine, berberine, and jatrorrhizine in Simiao Pills were higher than those in Sanmiao Pills. The intestinal absorption and plasma concentrations of alkaloids in Simiao Pills were significantly higher than those in Sanmiao Pills, suggesting that the composition of Simiao Pills was more conducive to the alkaloids into the blood to resist inflammation and lower uric acid.

Short-term outcomes of single incision plus one port laparoscopic surgery for colorectal cancer / 中华胃肠外科杂志

Objective: Although single port laparoscopic surgery has achieved good clinical results, many surgeons are discouraged by the difficulties of operation, conflict of instruments, lack of antagonistic traction, and straight-line perspective. Therefore, some surgeons have proposed a single incision plus one hole laparoscopic surgery (SILS+1) surgical method. This study explored the safety and feasibility of SILS+1 for radical resection of colorectal cancer. Methods: A descriptive cohort study was carried out. The clinical data, including the operation, pathology and recovery situation, of 178 patients with colorectal cancer undergoing SILS+1 at Department of General Surgery, Nanfang Hospital, Southern Medical University from March 2018 to January 2019 were prospectively collected and retrospectively analyzed. Clavien-Dindo criteria was used for postoperative complication evaluation and visual analog scale was used for pain standard. Follow-up studies were conducted through outpatient service or telephone and the follow-up period was up to May 2019. Results: A total of 178 patients with colorectal cancer underwent SILS+1, including 111 male patients (62.4%) with an average age of 59 years. Eleven (6.2%) patients received added 1-3 operation ports during operation, and 1 patient was converted to open surgery due to ileocolic artery hemorrhage. The operative time was (135.2±42.3) minutes. The intraoperative blood loss was (34.6±35.5) ml. The number of harvested lymph nodes was 33.1±17.6. The distal margin was (4.7±17.8) cm. The proximal margin was (10.2±5.3) cm. Operation-related complications were observed in 16 patients (9.0%) within 30 days after the operation, of whom 6 had Clavien-Dindo III complications (3.4%). The postoperative pain scores were lower than 3. The average postoperative hospital stay was (5.6±2.6) days. Three patients (1.7%) returned to hospital within 30 days after operation due to intestinal obstruction and infection around stoma. The cosmetic evaluation of all the patients was basically satisfied. Conclusion: SILS+1 is safe and feasible in the treatment of colorectal cancer, and can reduce the postoperative pain.

The current situation of oncology pharmaceutical care ability of DTP pharmacy in China was evaluated and corresponding suggestions were put forward. RESULTS ：A total of 400 questionnaires were sent out ，and 392 valid questionnaires were collected with recovery rate of 98.0％. The cancer pharmacists in DTP pharmacy were mainly from East China ，mainly in Jiangxi （73 persons，18.62％），Anhui（68 persons，17.35％）. The pharmacists were mainly junior college or below （229 persons，58.42％）， followed by undergraduate （158 persons，40.31％）. The working years were more than 5 years（241 persons，61.48％）. The majors were mostly pharmaceutics （123 persons，31.38％），followed by pharmacy （including pharmacology ）（81 persons， 20.66％）. The regular knowledge sources of pharmacists in DTP pharmacy included learning materials （302 person times ， 77.04％），textbooks（250 person times ，63.78％）and Wechat push （206 person times ，52.55％）；the latest knowledge sources included training courses （347 person times ，88.52％），Wechat push （211 person times ，56.38％）and academic conferences （162 person times ，41.33％）. The expected training methods included online video courses （344 person times ，87.76％）and offline courses（248 person times ，63.27％）. In terms of prescription checking and dispensing ，there were mainly problems such as incomplete medical documents and materials ；82.91％ and 64.54％ of pharmacists needed routine medical records and discharge summary，and 91.58％ of pharmacists took the doctor ’s handwritten prescription as the basis for dispensing new anti-tumor drugs ； pharmacists paid less attention to allergy history ，genetic history and ADR in the field of drug consultation and guidance. According to DTP pharmacists ，the difficulties in the process of drug treatment management included patient ’s ADR monitoring （239 person times，60.97％），evaluating the rationality of drug use （222 person times ，56.63％），making a complete drug use record （219 person times ，55.87％）. The main follow-up visits of pharmacists were telephone （334 person times ，85.20％）and dispensing site （313 person times ，79.85％）. And 333 pharmacists（84.95％）thought it was necessary to make an appointment for dispensing ；the score rates of professional knowledge examination of antitumor pharmacy for the respondents were 40.56％-84.69％. In the aspect of pharmaceutical care management ，the main points of deduction were drug evaluation ，content and process of drug treatment management，drug follow-up and record ，and the proportion of deduction was 93％，86％ and 64％ respectively. In the on-site inspection，it was found that the pharmacist had a single source of working knowledge ，did not fully grasp the contents of the evaluation forms such as ADR classification standard ，and prescription checking did not meet the requirements. CONCLUSIONS ： DTP pharmacy in China develops rapidly under the guidance of relevant policies ，but its pharmaceutical care is still in the basic stage，which is far behind the requirements of providing whole-course pharmaceutical care for patients. It is necessary to improve the professional service ability of DTP pharma

Impact and related mechanisms of glucose fluctuations on aortic fibrosis in type 1 diabetic rats / 中华心血管病杂志

Objective: To investigate the impact and related mechanisms of glucose fluctuations on aortic fibrosis in rats with type 1 diabetes mellitus. Methods: After injection of streptozotocin (STZ), male Sprague Dawley (SD) (8-12 weeks) rats (n=24) were randomly divided into three groups in accordance with the random number table: controlled STZ-induced diabetes (C-STZ) group (n=8); uncontrolled STZ-induced diabetes (U-STZ) group (n=8); STZ-induced diabetes with glucose fluctuations (STZ-GF) group (n=8). After three weeks, rats were sacrificed and aorta was obtained, aortic fibrosis was detected by Masson trichrome staining. The expression of collagen type 1 (collagen Ⅰ) was tested by immunofluorescence. The expression of runt-related transcription factor 2 (Runx2) was tested by immunohistochemistry. The mRNA levels of collagen Ⅰ and Runx2 were detected by quantitative real-time PCR (qRT-PCR). The protein expressions of collagen Ⅰ, Runx2 and nuclear factor (NF)-κB were determined by Western blot. Primary rat aortic smooth muscle cells (VSMCs) were cultured in three conditions: normal glucose (NG), high glucose (HG) and glucose fluctuations (GF). Cells in GF group were incubated for 72 hours with glucose alternating between 5.5 and 25 mmol/L every 12 hours. TPCA-1, the inhibitor of NF-κB, the expression of collagenⅠin different groups of cells was tested by immunofluorescence. The protein expressions of collagen Ⅰ, Runx2 and NF-κB were also determined by Western blot. Results: (1) The quantitative ratios of the area of fibrosis in the C-STZ group, U-STZ group, STZ-GF group were (8.42±0.10)%, (21.30±0.74)% and (44.39±1.09)% (P<0.05), respectively. The means of integral optical density (IOD) of collagenⅠ in the three groups were 11.92±0.88, 50.04±3.56 and 77.52±2.69, respectively (P<0.05). The mRNA levels of collagenⅠ in the three groups were 1.00±0.10, 2.02±0.28 and 2.83±0.33, respectively (P<0.05). The protein expressions of collagenⅠ in the three groups were 1.05±0.03, 2.06±0.32 and 4.93±0.25, respectively (P<0.05). (2) The average IOD of Runx2 in the three groups were 150.00±7.35, 204.84±2.32 and 391.48±7.13, respectively (P<0.05). The mRNA levels of Runx2 in the three groups were 1.02±0.02, 1.27±0.04 and 2.18±0.12, respectively (P<0.05). The protein expressions of Runx2 in the three groups were 1.03±0.01, 2.34±0.36 and 4.52±0.75, respectively (P<0.05). (3) The protein expressions of NF-κB in the three groups were 1.02±0.01, 1.96±0.13 and 2.64±0.21, respectively (P<0.05).

Meningeal cysts complicated with tethered cord syndrome diagnosed by prenatal ultrasonography:a case report / 中华围产医学杂志

We reported a case diagnosed with meningeal cysts complicated with tethered cord syndrome based on prenatal ultrasound images at 37+5 gestational weeks, which also showed horseshoe kidney and intrahepatic vascular abnormalities (arteriovenous fistula) in the fetus. The gravida had a precipitate delivery at 39+4 gestational weeks. The anus of this newborn was about 1 cm in front of the normal position. Intrahepatic arteriovenous fistula and horseshoe kidney were detected by neonatal ultrasound and CT scan, and spinal cystic occupying lesion was found by lumbar-sacrum MRI. Intraspinal tumors were removed through spinal canal exploration and spinal cord tumor resection and were confirmed as ependymal cysts by pathological analysis, which was consistent with the prenatal diagnosis. Postoperative changes of lumbar spine was reported by CT scan after the operation. The baby received successful anoplasty when five months old and no abnormal growth or development were found when followed up to one year and eight months old. Raising awareness of tethered cord syndrome can help reduce missed diagnosis and misdiagnosis.

Characteristics and relationship of bone strength and body composition in pre- And post- menopausal Dongxiang women / 解剖学报

Objective To analyze the changes of bone strength and body composition in pre- and postmenopausal Dongxiang women and explore the impact of body composition change on bone strength. Methods From Sep. 2016 to Jul. 2018, 203 cases Dongxiang 41-50 year old women (102 cases of premenopause and 101 cases of postmenopause) of Gansu Province were selected by stratified random sampling method, whose bone strength and body composition indexes were measured by ultrasonic bone mineral density meter and body composition analyzer respectively. Results There were lower bone strength and muscle tissue composition in the postmenopausal Dongxiang women (P< 0.05), and there was higher fat tissue composition (P < 0.01). The prevalence of osteoporosis was higher in postmenopausal women (P < 0. 01). Pearson correlation analysis showed that muscle tissue composition was positively correlated with the bone strength (P<0. 01), and it was negatively correlated with fat tissue composition in the pre- and postmenopausal Dongxiang women (P < 0. 0 1). Multivariate linear stepwise regression analysis showed that limb muscle mass and subcutaneous fat mass were a protective factor and a risk factor for bone strength in pre- and post-menopausal Dongxiang women, respectively. Conclusion The bone strength of Dongxiang women was determined by muscle and fat tissue, and associated with the distribution of body composition. The relationship between bone strength and body composition was not affected by menopause. Menopause was an important factor that increased the incidence of osteoporosis in Dongxiang women, and we should reinforce osteoporosis prevention in postmenopausal Dongxiang women.

Change rule of ductus venosus blood flow spectrum of normal fetal of 11-40 weeks and its clinical significance / 吉林大学学报(医学版)

Objective:To explore the correct test ways of the ductus venosus (DV) blood flow spectrum of the normal fetal and the rule of changes of the normal fetal DV blood flow spectrum along with gestational week,and to establish the reference ranges of the parameters of blood flow.Methods:A total of 320 cases of single fetal pregnant women within 11-40 weeks were selected as the objects.Using color doppler echocardiography,the ventricular systolic peak velocity (SV),atrial systolic trough (aV),pulse index (PI) and resistance index (RI)were measured,and the ratio of ventricular systolic peak velocity trough ratio (S/a) from ultrasonic standard section was calculated.All of these were analysed statistically.Results:The doppler spectrum of normal fetal DVblood flow showed the same three-phase waves,SV was increased with the increase of gestational age (F=27.00,P=0.000),and aV was elevated with the increase of gestational age (F=389.81,P=0.000),while PI (F=65.41,P=0.000),RI (F=58.82,P=0.000) andS/a ratio (F=47.79,P=0.000) were decreased with the increase of gestational age.Conclusion:The performance of color Doppler flow imaging of normal fetal DV showed that the blood flow peak speed is increased along with the increase of gestational age and PI,RI and S/a are reduced with the increase of gestational age,and RI has the largest decline,which has important diagnosis value.

Clinical practice guidelines for the treatment of primary liver cancer with integrative traditional Chinese and Western medicine / 中西医结合学报

Traditional Chinese medicine (TCM) is an important part of the treatment of primary liver cancer (PLC) in China; however, the current instructions for the integrative use of traditional Chinese and Western medicine for PLC are mostly based on expert opinion. There is no evidence-based guideline for clinical practice in this field. Therefore, the Shanghai Association of Chinese Integrative Medicine has established a multidisciplinary working group to develop this guideline, which focuses on the most important questions about the use of TCM during PLC treatment. This guideline was developed following the methodological process recommended by the World Health Organization Handbook for Guideline Development. Two rounds of questionnaire survey were performed to identify clinical questions; published evidence was searched; the Grading of Recommendations Assessment, Development and Evaluation approach was used to evaluate the body of evidence; and recommendations were formulated by combining the quality of evidence, patient preferences and values, and other risk factors. The guideline was written based on the Reporting Items for Practice Guidelines in Healthcare tool. This guideline contains 10 recommendations related to 8 questions, including recommendations for early treatment by TCM after surgery, TCM combined with transcatheter arterial chemoembolization for advanced PLC, TCM drugs for external use, and acupuncture and moxibustion therapy.

Change of Inflammatory Factors in Patients with Acute Coronary Syndrome / 中华医学杂志(英文版)

<p><b>Background</b>Acute coronary syndrome (ACS) is closely related to unstable plaques and secondary thrombosis. The inflammatory cells in plaques and their inflammatory products may be the cause for plaque instability and ruptures. The study aimed to disclose the changes of inflammatory factors including serum intracellular adhesion molecule-1 (ICAM-1), chitinase-3-like protein 1 (YKL-40), and lipoprotein-associated phospholipase A2 (Lp-PLA2) in patients with ACS and its clinical significance.</p><p><b>Methods</b>A total of 120 patients with coronary heart disease (CHD) were categorized into 2 groups: 69 with ACS and 51 with stable angina pectoris (SAP); 20 patients with chest pain and normal angiography served as a control group. The 120 patients with CHD were categorized into single-vessel disease group, double-vessel disease group, and three-vessel disease group based on the number of coronary artery stenosis. The severity of coronary artery stenosis was quantified based on coronary angiography using Gensini score. They were further divided into mild CHD group with its Gensini score <26 (n = 36), moderate CHD group with its Gensini score being 26-54 (n = 48) and severe CHD group with its Gensini score >54 (n = 36). Serum levels of ICAM-1, YKL-40, and Lp-PLA2 of different groups were determined by enzyme-linked immunosorbent assay. Correlation between ICAM-1, YKL-40, Lp-PLA2, and Gensini score was analyzed.</p><p><b>Results</b>The levels of serum inflammatory factors ICAM-1, YKL-40, and Lp-PLA2 were significantly higher in the ACS group than those in control group and SAP group (all P < 0.05); and compared with control group, no significant difference was observed in terms of the serum ICAM-1, YKL-40, and Lp-PLA2 levels in the SAP group (P > 0.05).The levels of serum ICAM-1, YKL-40, and Lp-PLA2 were not significantly different among control group, single-vessel disease group, double-vessel disease group, and three-vessel disease group (all P > 0.05). The levels of serum ICAM-1, YKL-40, and Lp-PLA2 were not significantly different among control group, mild CHD group (Gensini score <26), moderate CHD group (Gensini score 26-54), and severe CHD group (Gensini score >54) (all P > 0.05). Nonparametric Spearman correlation analysis showed that the levels of serum ICAM-1, YKL-40, and Lp-PLA2 were not correlated with the Gensini score in CHD patients (r = 0.093, r = -0.149, and r = -0.085, all P > 0.05; respectively).</p><p><b>Conclusions</b>The serum levels of ICAM-1, YKL-40, and Lp-PLA2 were correlated with different clinical types of CHD, but not well correlated the severity and extent of artery stenosis, suggesting that ICAM-1, YKL-40, and Lp-PLA2 might be involved in occurrence of instability of atherosclerotic plaque, and might reflect the severity of CHD mostly through reflecting the plaque stability.</p>
