Objective To evaluate the olfactory function and its influence factors by using Sniffin ’ Sticks test, and to compare the quality of Parkinson ’s disease (PD) recognition between Sniffin’ Sticks and 16 kinds of odor identification in Sniffin ’ Sticks(SS-16) tests.Methods The Sniffin’Sticks test was used to assess the olfactory function of 68 PD patients and 76 healthy volunteers , and the relationship between smell and age, disease duration, Unified Parkinson’ s Disease Rating Scale score, Hoehn-Yahr (H-Y) rating, and cognitive function level (Montreal Cognitive Assessment) was analyzed.Results (1)The prevalence of olfactory dysfunction in PD group (83.3%) was significantly higher than that in control group (21.2%).The Sniffin’ Sticks test showed that the odor threshold score (6.6 ±3.2, P=0.000), odor discrimination score (6.6 ±3.3, P=0.000), 16 kinds of odor identification score (6.8 ±2.4, P=0.000) in PD group were significantly lower than those in control group.( 2 ) When comparing the PD cases and healthy controls in recognition , the sensitivity and the specificity of the Sniffin ’ Sticks test were 0.897 and 0.737, respectively, similar to the SS-16 test.However, the Sniffin’ Sticks test showed advantage compared with odor threshold and odor discrimination.( 3 ) The olfactory score in PD group was positively correlated with cognitive function (r=0.243, P=0.046), and was unrelated with age, gender, disease duration, and disease severity.The olfactory score in control group was negatively correlated with age (r=-0.270, P=0.018), but positively correlated with cognitive function (r=0.281, P=0.014).Conclusions There is a higher incidence of olfactory dysfunction in PD patients than in control group.Sniffin’ Sticks test is superior to SS-16 test in quantitative and qualitative analysis of olfactory function in PD patients.Two tests both have high sensitivity and specificity in the recognition of PD .

This paper provides a method of positioning the ultrasound probe in MR system. Machining 6 slots or cylinder perpendicular to the ultrasound probe surface on the edge of ultrasound probe as markers, 12 central cylinder ends are chosen as positioning points. By calculating these positioning points' coordinates in MR's coordinate system, the coordinate transformation between the ultrasound and MR coordinate system can be computed. Furthermore, by taking advantage of redundant information, calculating errors can be reduced and the precision can be improved.

The abnormal lipid levels caused by disorders of lipid metabolism are important factors leading to various diseases such as cardiovascular and cerebrovascular damage .Studies found that monitoring blood lipid levels can provide evidences for the early diagnosis of cardiovascular and cerebrovascular diseases, assessing the risks of cardiovascular and cerebrovascular diseases , and evaluation of the therapeutic effects. The commonly used lipid markers for the diagnosis of clinical cardiovascular and cerebrovascular diseases are the four routine blood lipids , such as total cholesterol ( TC) , total triglyceride (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL).The application of other blood lipid markers including apolipoprotein A (ApoA), apolipoprotein B (ApoB), non high density lipoprotein cholesterol (non-HDL-C), and lipoprotein a[Lp (a)]in the diagnosis and treatment of cardiovascular and cerebrovascular diseases have also been reported .

Objective To compare the curative efficacy of conventional transcatheter arterial chemoembolization(C-TACE)and drug-eluting bead transcatheter arterial chemoembolization(D-TACE)combined with local thermal ablation in the treatment of massive hepatocellular carcinoma(HCC).Methods A total of 72 patients with massive HCC,who were admitted to the Nanyang Municipal First People's Hospital of China from April 2018 to June 2021,were enrolled in this study.By using random number table method,the patients were divided into study group(n=36)and control group(n=36).The patients of the control group were treated with local thermal ablation combined with C-TACE,while the patients of study group were treated with local thermal ablation combined with D-TACE.The clinical efficacy,tumor markers,liver function,serological indicators,blood perfusion indexes,and adverse reactions were compared between the two groups.All patients were followed up for two years.The progression-free survival(PFS)were compared between the two groups.Results The disease control rate(DCR)and objective response rate(ORR)in the study group were higher than those in the control group(P＜0.05).At 3 months after operation,the levels of alpha-fetoprotein(AFP)and prothrombin induced by Vitamin K absence or antagonist-Ⅱ(PIVKA-Ⅱ)were decreased in both groups(P＜0.05),which in the study group were obviously lower than those in the control group(P＜0.05);the alanine aminotransferase(ALT)level was increased in both groups,which in study group was lower than that in the control group(P＜0.05);the albumin(ALB)level was decreased in both groups(P＜0.05),which in the study group was higher than that in the control group(P＜0.05);the epidermal growth factor receptor(EGFR),vascular endothelial growth factor(VEGF)and thymokinase 1(TK1)levels were decreased in both groups(P＜0.05),which in the study group were lower than those in the control group;the blood volume(BV)and blood flow(BF)were decreased in both groups(P＜0.05),which in the study group was lower than those in the control group;the mean transit time(MTT)of contrast agent was increased in both groups(P＜0.05),which in the study group was higher than that in the control group.During the follow-up of two years,one patient in each group was lost in touch,the follow-up success rate was 97.22％.The median PFS in the study group and the control group was 15.41 months(95％CI:7.02-23.19)and 12.34 months(95％CI:6.16-22.30)respectively.The PFS curve of the study group was better than that of the control group(P＜0.05).Conclusion Local thermal ablation combined with D-TACE can improve liver function and blood perfusion in patients with massive HCC,with a remarkable clinical efficacy.This therapy can reduce tumor markers levels,regulate serum EGFR,VEGF and TK1 expressions,and prolong the median PFS,besides,it is clinically safe and reliable.

The aim of the study was to develop a simple, rapid and accurate LC-MS/MS method for the determination of digoxin.Digoxin-d3 was taken as the internal standard (IS), and sample preparation was achieved by liquid-liquid extraction.Chromatographic separation was performed on a Kinetex C18 column (2.1 mm × 50 mm, 2.6 μm; Phenomenex) using an isocratic elution with merely 2 min for each sample.The mobile phase consisted of water and acetonitrile solutions, both containing 1 mmol/L ammonium acetate and 1 mmol/L formic acid (55∶45).The detection was conducted on a TripleQuadTM 4500MD mass spectrometer coupled with electrospray ionization interface under positive-ion multiple reaction monitoring mode.The transitions were m/z 798.5 → 651.3 and m/z 801.6 → 654.4 for digoxin and digoxin-d3, respectively.Results showed that the method was linear over the range of 0.100-20.0 ng/mL.The selectivity, accuracy and precision, recovery and stability of the method were all within the acceptable limits with no matrix effect.This method was successfully applied to a girl treated with digoxin with substantial improvement of therapeutic effect and elimination of toxic reaction, so it can provide valuable fuidance and reference for individualized medication in clinical practice.

Objective:To explore the correlation between the index of hemodynamics in perinatal period and retinopathy of prematurity(ROP), so as to provide basis for the better prevention and treatment of ROP.Methods:From May 2017 to April 2019, the preterm infants were admitted to the Neonatal Intensive Care Unit of the First Affiliated Hospital of Zhengzhou University at birth and were hospitalized for more than 2 weeks, gestational age ≤ 35 weeks and birth weight ≤ 2 500 g. They were selected as the study objects.The perinatal data including heart rate, blood pressure, patent ductus arteriosus, ventricular septal defect, and NT-proBNP level on the 1 st, 7 th and 14 th day, respectively after birth were collected.They were divided into ROP group and non ROP group according to the results of the retinopathy screening report.The influencing factors of ROP were screened out by univariate analysis and multivariate regression analysis. Results:A total of 1 119 subjects were included, 105 infants with ROP were detected, and the prevalence of ROP was 9.4%.Among them, 12 cases of pre-threshold lesion type 1 and threshold lesions required treatment, accoun-ting for 1.07% of screened preterm infants .Univariate analysis and multivariate regression analysis revealed that gestational age, birth weight, total oxygen therapy time, and intrauterine growth restriction were all factors affecting ROP, and 2 hemodynamic related indicators, such as the level of NT-proBNP in plasma on the 14 th day after birth, and placenta previa or abruption were also related to ROP( OR=0.604, 0.647, 1.276, 2.361, 1.688 and 2.506, respectively, all P<0.05). Conclusion:The hemodynamic changes in perinatal period may be involved in the formation of ROP, and it is necessary to further clarify its mechanism.

Objective : To explore the main points of clinical treatment of fourth branchial cleft deformity in special positions and to provide a reference for clinical practice. Methods: The clinical data of one case of a fourth branchial cleft deformity that occurred in the left anterior chest wall with a fistula below the clavicle are summarized and combined with a literature review. Results: The patient complained of repeated swelling and pain under the left anterior chest wall for 2 months. A 10 mm×10 mm fistula with yellow clear liquid exudate from the fistula was observed on the left side below the clavicle. A 20 mm×20 mm×10 mm swelling was immediately adjacent at the superficial cervicothoracic junction of the upper sternoclavicular joint, with no fluctuation and poor activity; this swelling produced slight pain upon pressing. Imaging examinations pointed to cystic lesions. The primary diagnosis was a fourth branchial deformity. A small amount of methylene blue was injected into the patient's subclavian fistula, and a supraclavicular T-shaped incision was made where the cyst contacted the fistula. By turning the flap, all the methylene blue-stained areas and adjacent submucosal tissues were exposed. During the operation, a mass was found on the sternum. The platysma was found deep in the notch, which was incised before excising the surrounding area. The pathological result is the fourth branchial cleft deformity. After 1 week and 3 months of follow-up, the patients had no discomfort and no recurrence. A review of the relevant literature shows that the fourth branchial cleft deformity is a congenital developmental abnormality that occurs in 1% of all branchial cleft deformity. It often presents as a fistula, cyst, or sinus tract and is anatomically located at the neck root and supravicular region. The fistula is close to the medial lower boundary of the sternocleidomastoid muscle. The diagnosis is often made based on its anatomical location, imaging examinations and, ultimately, pathology. The differential diagnoses include other cervical swellings, such as hemangioma and a thyroglossal duct cyst. Surgical resection is a commonly used treatment method. In recent years, endoscopic positioning and internal fistula burning have had good curative effects for recurrent fourth branchial cleft deformity, with a small chance of recurrence or cancer. Conclusion Given its unique position, clinicians should make full use of imaging methods to determine the size, anatomical location and course of the lesion when treating the fourth branchial cleft deformity to ensure the complete and safe surgical resection of the lesion and prevent recurrence.

Objective: To explore the relationship between serum complement 1q (C1q) and C1q/tumor necrosis factor-related protein 1 (CTRP1) levels in patients with coronary atherosclerotic heart disease (CHD) and their clinical value. Methods: Case-control study.115 patients with CHD who were hospitalized in the Department of Cardiology of Ningxia Medical University General Hospital from January 2018 to November 2018 were selected as the case group, including 72 males and 43 females, aged 35-82 years, average (59.96±9.49) years old. There were three subgroups: stable angina group (SAP, n=12), unstable angina group (UA, n=69), and acute myocardial infarction group (AMI, n=34). The control group was selected from 43 healthy subjects in the same period, including 21 males and 22 females, aged 23-71 years, with an average of (45.00±10.66) years old. Serum C1q and CTRP1 levels were tested by immunoturbidimetry and ELISA, and other biochemical indicators such as triglyceride (TG) and total cholesterol (CHOL) were detected.Multiple linear regression was used to analyze the influence of various factors on C1q level. ROC curve and area under the curve (AUC) to explore the diagnostic value of C1q and CTRP1. Results: The C1q level in the CHD group (184.06±31.05) mg/L was higher than that in the control group (122.22±28.18) mg/L (t=-11.405, P<0.001). The AMI group (192.80±34.08) mg/L was significantly higher than the SAP group (169.17±27.13) mg/L (t=-2.328, P=0.021).The CTRP1 level in the CHD group [241.85(79.38)] ng/ml was lower than that in healthy control group [292.7(67.64)] ng/ml (Z=-3.64, P<0.001). Group B with higher Gensini score (t=3.672, P<0.001) and group C (t=2.529, P=0.013) had higher C1q levels than group A.After adjusting for the effects of age, sex and other indicators, C1q levels were correlated with HDL-C (β=-0.582, P<0.001),CHOL (β=0.384,P<0.001) and systolic blood pressure (β=0.142,P=0.038). The ROC curve shows that when the CHD is diagnosed, the sensitivity of C1q level >150.82 mg/L is 87%,the specificity is 88.4%, and the AUC is 0.942. The corresponding sensitivity and specificity of CTRP1 <281.80 ng/ml are 76.5% and 60.5% respectively, and the AUC is 0.688. The AUC obtained by combined predictors was 0.944, and the sensitivity and specificity were 89.6% and 86.0% respectively. When AMI is diagnosed, C1q level >178.3 mg/L, corresponding sensitivity and specificity are 70.6% and 66.1%, the AUC is 0.726, CTRP1 has no diagnostic value. Conclusions Serum C1q levels in patients with CHD are elevated, and AMI patients are higher than SAP patients; C1q may be a potential marker reflecting the severity of coronary artery disease; there is no significant correlation between serum C1q and CTRP1 in CHD patients.

Colorectal cancer （CRC）， a most common malignant tumor of the digestive tract， is often manifested by abdominal pain， changes in stool quality， blood in the stool， and weight loss， with rising morbidity and mortality year by year. The onset and development of CRC involve a variety of mechanisms， in which tumor microenvironment （TME） and tumor-associated macrophages （TAMs） have received increasing attention. TAMs influence the tumor development via immune escape and angiogenesis promotion and are associated with the prognosis of tumors. In recent years， traditional Chinese medicine （TCM） has been widely researched and applied in the treatment of cancers. Studies have discovered that TCM mainly exerts the therapeutic effects on CRC by inhibiting the proliferation， metastasis， and angiogenesis， promoting the apoptosis， and inducing autophagy of tumor cells and boosting the immune function. TCM as an effective treatment approach can regulate TAMs to inhibit tumor growth. Moreover， the active components and targets of TCM can be taken as new research directions of immunotherapy. This review describes TAMs and their roles in CRC progression and summarizes the molecular targets and mechanisms of different active components， compound prescriptions， and novel preparations of TCM against CRC， aiming to provide a mechanism reference for the clinical treatment of CRC with TCM and give new insights into the in-depth research on the prevention and treatment of CRC-related diseases with TCM.
