ABSTRACT
Objective To study the status of diabetic foot and its related factors in Hanzhong area in recent years, and to provide a scientific basis for the prevention and management of diabetic foot complicated by type 2 diabetes. Methods A stratified sampling method was used to select 528 patients with type 2 diabetes among permanent residents in Hanzhong from April 2016 to April 2022. Relevant medical history and laboratory examination data were collected, and the incidence of diabetic foot was calculated. The influence of related factors on the risk of diabetic foot was analyzed by regression model. Results Among 528 subjects in this study, the disease course and body type of T2DM showed that male patients had significantly longer disease, and the proportion of overweight and obesity was higher, P2=27.516，P<0.05）. The proportion of male patients complicated with diabetic foot was higher than that of female patients (P<0.05). At the same time, the incidence of Wagner Grade I was higher in males than in females (P<0.05). The effects of potential factors on the risk of diabetic foot were discussed by gender. Univariate analysis and multivariate logistic regression analysis indicated that the risk factors of diabetic foot in male T2DM patients included: Increased course of disease, increased age, poor blood glucose control, increased total cholesterol level, increased BMI level and increased platelet to lymphocyte ratio . Potential risk factors in women include increased course of disease, age, poor blood sugar control (increased glycosylated hemoglobin levels) and increased platelet to lymphocyte ratios in all cases（P<0.05）. Conclusion The current prevalence rate of type 2 diabetes patients complicated with diabetes foot in Hanzhong area is 16.29%, which is still high , and the prevalence rate of men is significantly higher than that of women. Older age, long duration of T2DM, poor blood glucose control, increased total cholesterol level, increased blood uric acid level, decreased urine pH value, and increased platelet lymphocyte ratio are potential risk factors for diabetes foot. Male patients should also pay attention to the occurrence of overweight and obesity tendency to reduce the risk of diabetes foot.
ABSTRACT
Aim To screen and study the expression of long non-coding RNA (IncRNA) in rats with middle cerebral artery occlusion (MCAO) with MCAO treated with Tao Hong Si Wu decoction (THSWD) and determine the possible molecular mechanism of THSWD in treating MCAO rats. Methods Three cerebral hemisphere tissue were obtained from the control group, MCAO group and MCAO + THSWD group. RNA sequencing technology was used to identify IncRNA gene expression in the three groups. THSWD-regulated IncRNA genes were identified, and then a THSWD-regu-lated IncRNA-mRNA network was constructed. MCODE plug-in units were used to identify the modules of IncRNA-mRNA networks. Gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) were used to analyze the enriched biological functions and signaling pathways. Cis- and trans-regulatory genes for THSWD-regulated IncRNAs were identified. Reverse transcription real-time quantitative pol-ymerase chain reaction (RT-qPCR) was used to verify IncRNAs. Molecular docking was used to identify IncRNA-mRNA network targets and pathway-associated proteins. Results In MCAO rats, THSWD regulated a total of 302 IncRNAs. Bioinformatics analysis suggested that some core IncRNAs might play an important role in the treatment of MCAO rats with THSWD, and we further found that THSWD might also treat MCAO rats through multiple pathways such as IncRNA-mRNA network and network-enriched complement and coagulation cascades. The results of molecular docking showed that the active compounds gallic acid and a-mygdalin of THSWD had a certain binding ability to protein targets. Conclusions THSWD can protect the brain injury of MCAO rats through IncRNA, which may provide new insights for the treatment of ischemic stroke with THSWD.
ABSTRACT
Aim To anticipate the mechanism of zuka- mu granules (ZKMG) in the treatment of bronchial asthma, and to confirm the projected outcomes through in vivo tests via using network pharmacology and molecular docking technology. Methods The database was examined for ZKMG targets, active substances, and prospective targets for bronchial asthma. The protein protein interaction network diagram (PPI) and the medication component target network were created using ZKMG and the intersection targets of bronchial asthma. The Kyoto Encyclopedia of Genes and Genomics (KEGG) and gene ontology (GO) were used for enrichment analysis, and network pharmacology findings were used for molecular docking, ovalbumin (OVA) intraperitoneal injection was used to create a bronchial asthma model, and in vivo tests were used to confirm how ZKMG affected bronchial asthma. Results There were 176 key targets for ZKMG's treatment of bronchial asthma, most of which involved biological processes like signal transduction, negative regulation of apoptotic processes, and angiogenesis. ZKMG contained 194 potentially active components, including quercetin, kaempferol, luteolin, and other important components. Via signaling pathways such TNF, vascular endothelial growth factor A (VEGFA), cancer pathway, and MAPK, they had therapeutic effects on bronchial asthma. Conclusion Key components had strong binding activity with appropriate targets, according to molecular docking data. In vivo tests showed that ZKMG could reduce p-p38, p-ERKl/2, and p-I
ABSTRACT
Objective: To summarize the clinical and genetic characteristics of children with β-ketothiolase deficiency (BKTD). Methods: The clinical characteristics, biochemical, markers detected by tandem mass spectrometry (MS/MS) and gas chromatography-mass spectrometry (GC/MS), as well as the variants in ACAT1 gene among 5 children with BKTD in Children's Hospital of Chongqing Medical University between October 2018 and December 2022 were retrospectively analyzed. Results: The onset age of the disease in 5 patients (4 males and 1 female) ranged from 9.7 to 28.0 months. During the acute phase, severe metabolic acidosis was observed with a pH of 6.9-7.1, as well as hypoglycaemia (2.3-3.4 mmol/L) and positive urinary ketone bodies (+-++++). Blood levels of methylcrotonyl carnitine, methylmalonyl carnitine and malonyl carnitine were 0.03-0.42, 0.34-1.43 and 0.83-3.53 μmol/L respectively and were significantly elevated. Urinary 2-methyl-3-hydroxybutyric acid was 22-202 and 3-hydroxybutyric acid was 4-6 066, both were higher than the normal levels. Methylcrotonylglycine was mild elevated (0-29). The metabolites detected by MS/MS and GC/MS were significantly reduced after treatment. Analysis of ACAT1 gene mutation was performed in 5 children. Most variants were missense (8/9). Four previously unreported variants were identified: c.678G>T (p.Trp226Cys), c.302A>G (p.Gln101Arg), c.627_629dupTGA (p.Asn209_Glu210insAsp) and c.316C>T (p.Gln106Ter), the first 2 variants were predicted to be damaging by SIFT, PolyPhen-2 and Mutation Taster software. c.316C>T (p.Gln106Ter) is a nonsense variant. Conclusions: β-ketothiolase deficiency is relatively rare, lacks specific clinical manifestations, however severe metabolic acidosis, hypoglycemia, and ketosis during the acute onset were consistent findings. Missense mutations in the ACAT1 gene are common genetic causes of β-ketothiolase deficiency.

Gender, age, and axial length are also related to macular blood flow parameters.
ABSTRACT
Objective:To investigate the current status of hospitalized neonatal death of different gestational ages in Shaanxi Province.Methods:All neonatal deaths in six hospitals in Shaanxi Province from 2016 to 2020 were retrospectively analyzed, and the differences in perinatal complications, the causes of death, and the age at death were compared using Chi-square (or Fisher's exact ) test. Results:(1) Totally, 220 488 neonates were delivered in the obstetric department of the six hospitals during the study period; 71 782 out of them were admitted to the neonatal department. While 424 neonatal death was reported, giving the total hospitalized neonates mortality rate of 5.5‰ (394/71 782), which included 152 deaths of transferred patients ( n=9 103, 16.7‰), 226 premature (53.3%), 196 term (46.2%), and two post-term infants (0.5%). (2) Among mothers of dead neonates, 73.6% were found to have at least one perinatal complication. The most common one was fetal distress (146 cases, 34.4%), followed by gestational diabetes mellitus (113 cases, 26.7%), amniotic fluid abnormalities ( n=73, 17.2%), maternal infectious diseases ( n=71, 16.8%), and hypertensive disorders in pregnancy (HDP) ( n=52, 12.3%). The lower the gestational age, the higher the proportion of multiple pregnancies and assisted reproduction technology applied (Fisher exact test, P<0.05). On the contrary, the higher the gestational age, the higher the cesarean section rate ( χ 2=26.69, P<0.001). HDP was more likely to occur in the gestational age of 28-31 +6 and 32-34 +6 weeks ( χ 2=37.16, P<0.001), and amniotic fluid abnormalities were more likely to occur in those over 37 weeks ( χ 2=27.47, P<0.001). (3) The five leading causes of neonatal death were neonatal respiratory distress syndrome (NRDS, n=100, 23.6%), neonatal asphyxia ( n=88, 20.8%), maternal infectious diseases ( n=80, 18.9%), and birth defects ( n=54, 12.7%), and pulmonary hemorrhage ( n=22, 5.2%). The first three causes of death in term and post-term infants were neonatal asphyxia ( n=65, 32.8%), birth defects ( n=42, 21.2%), and infectious diseases ( n=26, 13.1%). NRDS ( n=83, 36.7%), infectious diseases ( n=54, 23.9%), and neonatal asphyxia ( n=23, 10.2%) were the three leading causes of death of premature babies. (4) Out of the 326 (76.9%) neonatal deaths within seven days after birth, 162 (38.2%) died within 24 h after birth and 164 cases (38.7%) between one to seven days after birth. Conclusions:Most neonatal deaths occurred among preterm ones and within seven days after birth, whose mothers suffered perinatal complications. The causes of neonatal death vary among different gestational age groups.
ABSTRACT
Objective:To analyze the distribution characteristics of special types of diabetes in China, in order to provide a theoretical basis for the diagnosis and treatment of special types of diabetes.Methods:Pubmed, CNKI, and WanFang Data were searched for the case reports and clinical studies of special types of diabetes in China from 2011 to 2021. After independent literature screening by 2 researchers according to the inclusion and exclusion criteria, diseases and the number of corresponding cases included were extracted for statistics. The etiological composition and disease characteristics of three subtypes of special type diabetes were analyzed.Results:A total of 613 articles(7 377 patients)were included and roughly divided into eight subtypes of special type diabetes according to etiological classification for disease composition analysis. The results by ratio in descending order were as follows: mono-genetic gene defects in islet β-cell function, pancreatogenic diabetes, diabetes induced by drugs or chemicals, endocrine disease, mono-genetic gene defects in insulin action, other genetic syndromes associated with diabetes, infection, and uncommon immune-mediated diabetes. The disease composition of the three subtypes of special types of diabetes that we focused on were mono-genetic gene defects in islet β-cell function(50.21%), pancreatogenic diabetes(35.65%), and mono-genetic gene defects in insulin action(1.56%). The composition analysis of the special types of diabetes in each subtype showed that neonatal diabetes mellitus(NDM, n=1 749, 23.71%)and maturity onset diabetes in young(MODY, n=1 554, 21.07%)accounted for the largest proportions. According to the composition analysis of each subtype of MODY patients, the top three subtypes were MODY2(50.89%), MODY3(16.03%), and MODYX(8.91%). In addition, taking MODY as an example, patients with de novo mutations(DNMs)and(or)new mutation sites were summarized and analyzed. The results revealed 31 MODY patients with DNMs(1.99%) and 339 MODY patients with new mutation sites(21.81%). Conclusions:According to the literature analysis, NDM and MODY represent the largest proportion of patients with special type diabetes in China. MODY2 patients make up the largest proportion of MODY patients. In addition, diabetic patients carrying DNMs and(or)new mutation sites should be taken seriously.

The results of Pearson correlation analysis showed that the level of CTGF had positive correlation with GLO-Ⅰ and PKM2 ( r = 0.713, 0.741, P<0.05), and the level of GLO-Ⅰ had positive correlation with PKM2 ( r = 0.823, P<0.05). The results of Spearman correlation analysis showed that the levels of CTGF, GLO-Ⅰ, PKM2 had positive correlation with FIGO stage ( r = 0.609, 0.704, 0.721; P<0.05), myometrial invasion depth ( r = 0.753, 0.695, 0.719; P<0.05), lymph node metastasis ( r = 0.776, 0.744, 0.640; P<0.05); had negative correlation with the degree of differentiation ( r = - 0.711, - 0.720, - 0.668; P<0.05). Conclusions:Serum CTGF, GLO-I, PKM2 expression levels are abnormally elevated in patients with endometrial cancer, which are significantly related to multiple clinicopathological characteristics.
ABSTRACT
Objective: To analyze the clinical characteristics and imaging features of occupational pulmonary thesaurosis induced by dust of iron and its compounds (OPTIDIC). Methods: A total of 230 cases of occupational welder's pneumoconiosis (OWP) patients or observation subjects were selected as the research subjects using the retrospective analysis method. They were diagnosed in four occupational disease diagnosis institutions in Shandong Province from 2010 to 2017. The high kV X-ray chest radiography or chest digital radiograph (hereinafter referred to as X-ray) were re-read to screen OPTIDIC patients. The clinical data of OPTIDIC patients were collected and analyzed. Results: Among the 230 cases, 56 cases were diagnosed as OPTIDIC, accounting for 24.3%. The clinical symptoms of the 56 patients with OPTIDIC were cough, sputum, chest tightness, shortness of breath, and difficulty breathing, while their physical signs were low or coarse breath sounds in lungs and others. Most of the X-ray results showed p shadows or q shadows, accounted for 98.2%, of which p/p shadow and q/q shadow accounted for 62.5%. The result of chest computed tomography (CT) showed diffuse point/round shadow and diffuse glass shadow in OPTIDIC patients. The result of fibro-bronchoscopy showed that a large amount of iron lutein particles was accumulated in macrophages and biopsy of lung showed idiopathic pulmonary hemosiderosis in OPTIDIC patients. Conclusion: The clinical characteristics of OPTIDIC patients showed no different from OWP. However, the result of X-ray of OPTIDIC patients mainly showed small circular shadows, and their CT images mainly showed diffuse point/round shadows or grinding glass shadow, which could be used to the differential diagnosis of OPTIDIC and OWP.
ABSTRACT
ObjectiveTo understand the physical development level of 3-7 years old children in Zhag′yab， and to provide reference for local health decision-making. MethodsA cross-sectional study was conducted between June 2021 and July 2021， with a sample of 1 247 Tibetan children aged 3-7 years from kindergartens in 13 districts of Zhag′yab. Their height and weight were measured and the hemoglobin was detected by a unified method. Standard statistical method was adopted （Z-score method）. Z-scores of length /height-for-age （HAZ）， Z-scores of weight-for-age （WAZ）， Z-scores of body mass index （BMI）-for-age （BAZ） and Z-scores of weight-for-height （WHZ） were calculated by WHO Anthro v3.2.2 and WHO Anthro Plus. The nutritional status of children was evaluated according to WHO diagnostic criteria for malnutrition and anemia. ResultsThe average WAZ and HAZ of children aged 3 to 7 in Zhag′yab were lower than the WHO standards，except for the WAZ of 4-year old， the differences were statistically significant （P<0.05）. The overall detection rate of malnutrition was 25.7%， stunting， underweight， wasting， overweight， obesity and anemia were 11.6%， 11.8%， 10.8%， 3.3%， 1.8% and 29.3%， respectively. The detection rates of all indicators in boys were higher than those in girls， and the differences were not statistically significant （P>0.05）. The overweight rate and obesity rate of rural children were lower than those of urban children， and the other detection rates were higher than those of urban children. The differences of underweight rate， obesity rate and anemia rate were statistically significant between urban and rural children （P<0.05）. Among the detection rates of all indicators in different age groups， there were statistically significant differences in the overweight rate and the anemia rate （P<0.05）. The overweight rate of children aged 4 and the anemia rate of children aged 5 were the highest. ConclusionsThe physical development of children aged 3 to 7 in Zhag′yab is poor， and the prevalence of malnutrition and anemia is high. Underweight and anemia are more serious in rural children， and the overweight and obesity problem of urban children is emerging. More attention should be paid to promote their nutritional status. The prevention and intervention of children’s malnutrition should be strengthened in Zhag′yab.
ABSTRACT
Direct acid hydrolysis of Dioscorea zingiberensis rhizomes for preparation of diosgenin is wildly used in the traditional industry， which uses a large amount of inorganic acid catalysts， with high wastewater discharge and serious environmental pollution. Therefore， exploring clean and efficient preparation methods and processes has become an inevitable choice to realize the sustainable development of industrial production of diosgenin. Herein， the author reviewed and analyzed the research progress and problems of enzymatic hydrolysis， microbial transformation and modified acid hydrolysis in the preparation of diosgenin from D. zingiberensis rhizomes during the last ten years， and their application prospects are analyzed. Enzymatic hydrolysis has mild reaction conditions， but the yield of diosgenin is low， the economic cost is high， and the purification process of active enzyme is complicated. Microorganism shows specific activity to the substrate and high efficiency for diosgenin production， and microbial transformation is clean and environmentally friendly， but microbial transformation is time-consuming and the metabolic intermediates are complicated. For the modified acid hydrolysis， two-phase acid hydrolysis can reduce the amount of acid catalyst， and sulfonic acid-functionalized ionic liquid displays good recyclable performance by replacing the traditional inorganic acid， however， the wastewater discharge should still be considered. Solid acid catalysts are non-corrosive and easy to be recycled， but the need to use ethanol as the reaction solvent has certain safety hazards， and the catalyst preparation process is cumbersome. In conclusion， exploring clean and efficient conversion methods is an important research trend for preparation of diosgenin from D. zingiberensis rhizomes. For the enzymatic hydrolysis， the key glycoside hydrolases in the bioconversion process should be explored in depth， the conversion pathway of enzymatic saponins and enzyme specificity should be fully elucidated， and efforts should be made to improve the efficiency of enzymatic hydrolysis. For the microbial transformation， we should accelerate its industrial application process based on selecting and breeding efficient transformation strains， and optimizing stable transformation systems and processes， and in-depth investigation of the mechanism of microbial transformation， fully elucidating the specific key hydrolases and its catalytic properties， and striving to improve the efficiency of microbial transformation. For the modified acid hydrolysis， novel acid catalytic system with simple structure， stable performance and good biodegradability should be explored and applied， which can effectively solve the problems of environmental pollution and production safety.
ABSTRACT
Iron metabolism is involved in the development and drug resistance of many malignancies, including multiple myeloma (MM). Based on recent studies on iron metabolism and MM, this paper reviews the relationship between iron metabolism and disease process of MM in terms of iron overload leading to ferroptosis in MM cells, the role of iron deficiency in oxidative respiration and proliferation of MM cells, and the interaction between ferroptosis and autophagy in the disease process. The mechanisms by which iron metabolism-related substances lead to MM cells' resistance to proteasome inhibitors (PI) through inducing redox imbalance and M2 macrophage polarization are also briefly described, aiming to provide a theoretical basis for the application of iron metabolism-related drugs to the clinical treatment of MM patients.

Objective: To examine the association of greenness exposure with waist circumference (WC) and central obesity in older adults in China. Methods: Based on the cross-sectional data from the Chinese Longitudinal Healthy Longevity Survey in 2017-2018, 14 056 participants aged 65 years and over were included. Demographic characteristics, lifestyle, WC, and other information were collected through a questionnaire and physical examination. Based on the satellite monitoring data of moderate-resolution imaging spectroradiometer (MODIS) provided by NASA, the annual mean of normalized difference vegetation index (NDVI) within a radius of 1 000 meters was obtained as the measurement value of greenness exposure. Multivariate linear regression model, multivariate logistic regression model, and restricted cubic splines (RCS) model were used to analyze the association and dose-response relationship between greenness exposure and WC and central obesity in older adults in China. Results: A total of 14 056 participants were enrolled with a median age of 84.0 years [IQR: 75.0-94.0 years]. About 45.0% (6 330) of them were male and 48.6% (5 853) were illiterate. There were 10 964 (78.0%) participants from rural. The mean of WC was (84.4±10.8) cm. Central obesity accounted for 60.2% (8 465), and the NDVI range was (-0.06, 0.78). After adjusting for confounding factors, the multivariate linear regression model showed that the change value of WC in the urban group [β (95%CI):-0.49 (-0.93, -0.06)] was smaller than that in the rural [-0.78 (-0.98, -0.58)] for every 0.1 unit increase in NDVI (Pinteraction=0.022). Compared with the Q1 group in NDVI, WC of Q2 and Q3 groups in rural decreased, and the β (95%CI) values were-1.74 (-2.5, -0.98) and-2.78 (-3.55, -2.00), respectively. The multivariate logistic regression model showed that after adjusting for confounding factors, the risk of central obesity decreased for urban and rural older adults with an increase of 0.1 unit in NDVI, and the OR (95%CI) values were 0.87 (0.80, 0.95) and 0.86 (0.82, 0.89), respectively (Pinteraction=0.284). Compared with the Q1 group in NDVI, the risk of central obesity in the Q2 and Q3 groups in rural was lower, and the OR (95%CI) values were 0.68 (0.58, 0.80) and 0.57 (0.49, 0.68), respectively. The results of the multivariate regression model with RCS showed that there was a non-linear association of NDVI with WC (Pnonlinear=0.006) and central obesity (Pnonlinear=0.025). Conclusion: Greenness exposure is negatively associated with WC and central obesity in older adults in China.
ABSTRACT
Objective To explore the inhibitory effects and mechanisms of benzodiazepines on Helicobacter pylori (Hp).Methods The Hp international standard strain ATCC43504 was treated with benzodiazepines diazepam,midazolam,and remimazolam,respectively.The treatments with amoxicillin and clarithromycin were taken as the positive controls,and that with water for injection as the negative control.The inhibition zone of each drug was measured by the disk diffusion method.The minimum inhibitory concentration(MIC)and minimum bactericidal concentration(MBC)of each drug against Hp were determined.Hp suspension was configured and treated with diazepam and midazolam,respectively.The bacterial suspension without drug added was used as the control group.The concentration of K+ in each bacterial suspension was measured by an automatic biochemical analyzer before drug intervention(T0)and 1(T1),2(T2),3(T3),4(T4),5(T5),6(T6),and 7 h(T7)after intervention.Hp urease was extracted and treated with 1/2 MIC diazepam,1 MIC diazepam,2 MIC diazepam,1/2 MIC midazolam,1 MIC midazolam,2 MIC midazolam,1 mg/ml acetohydroxamic acid,and water for injection,respectively.The time required for the rise from pH 6.8 to pH 7.7 in each group was determined by the phenol red coloring method.Results The inhibition zones of diazepam,midazolam,remimazolam,amoxicillin,clarithromycin,and water for injection against Hp were 52.3,42.7,6.0,72.3,60.8,and 6.0 mm,respectively.Diazepam and midazolam showed the MIC of 12.5 μg/ml and 25.0 μg/ml and the MBC of 25 μg/ml and 50 μg/ml,respectively,to Hp.The concentrations of K+ in the diazepam,midazolam,and control groups increased during T1-T7 compared with those at T0(all P<0.01).The concentration of K+ in diazepam and midazolam groups during T1-T4 was higher than that in the control group(all P<0.01).The time of inhibiting urease activity in the 1/2 MIC diazepam,1 MIC diazepam,2 MIC diazepam,1/2 MIC midazolam,1 MIC midazolam,and 2 MIC midazolam groups was(39.86±5.11),(36.52±6.65),(38.58±4.83),(39.25±6.19),(36.36±4.61),and(35.81±6.18)min,respectively,which were shorter than that in the acetohydroxamic acid group(all P<0.01)and had no significance differences from that in the water for injection group(all P>0.05).Conclusion Diazepam and midazolam exerted inhibitory effects on Hp,which may be related to the cleavage of Hp cells rather than inhibiting urease.

OBJECTIVE@#To observe the clinical effect and safety of acupuncture in treatment of neck pain due to cervical spondylosis.@*METHODS@#According to the patients' preference and acceptance for the interventions of neck pain induced by cervical spondylosis, an acupuncture group (221 cases) and a non-acupuncture group (251 cases) were divided. After the control of confounding factors with propensity score matching, 218 cases were included in either acupuncture group or non-acupuncture group. In the acupuncture group, acupuncture was applied to Dazhui (GV 14), Baihui (GV 20), ashi points, bilateral neck-Jiaji (EX-B 2), Fengchi (GB 20), Houxi (SI 3), Shenmai (BL 62), etc. The treatment was given once daily, one course of intervention was composed of 5 treatments and 3 courses were included. In the non-acupuncture group, the oral administration of imrecoxib tablets and cobalt tablets was prescribed for 2 weeks. Before and after treatment, the scores of Northwick Park questionnaire (NPQ) and the simplified McGill pain questionnaire (SF-MPQ) were observed, and the safety was assessed in patients of the two groups.@*RESULTS@#After treatment completion, the scores of NPQ and SF-MPQ were all reduced when compared with those before treatment in each group (P<0.001), and the scores of NPQ and SF-MPQ in the acupuncture group were lower than those of the non-acupuncture group (P<0.001). The incidence of adverse reactions was 6.0% (13/218) in the acupuncture group and was 10.1% (22/218) in the non-acupuncture group, without statistical significance in comparison (P>0.05).@*CONCLUSION@#Acupuncture is effective and safe in the relief of neck pain and the improvement of comprehensive quality of life in the patients with cervical spondylosis.

【Objective】 To explore the epidemiological features and relational factors of accidental death among children under 5 years of age in rural area of Shaanxi Province. 【Methods】 A case-control study was conducted in the research, and children under 5 years old in nine National surveillance counties of Shaanxi were collected. The questionnaire of national survey of accidental injuries among children under 5 years of age was used to investigate the basic information of children, socio-demographic characteristics, child care status, injury occurrence condition. The mean, standard deviation and percentage were used to describe the basic situation and main characteristics of accidental death. The Chi-square test and Logistic regression methods were performed to explore the relational factors of accidental death of children. 【Results】 Of the 25 cases of accidental death of children under the age of five years old, 5 were traffic accidents (20.0%), 9 cases were falling (36.0%), and 11 were suffocation (44.0%). Age distribution showed that children of accidental suffocation were younger, with 90.9% (10 cases) of them under the age of 1 years old. Gender distribution showed that traffic accident deaths occurred to boys. Area distribution showed that falling and suffocation death mainly happened in Hanzhong, while traffic accidents death mainly in Weinan. When the accident happened, 8 caregivers were not on the scene. What was worse, among 17 caregivers who were on the scene of accident, only 4 kept an eye on children. Compared with 25 children in control group, 16 in case group had received health examination, and the difference showed statistical significance (χ2=8.672, P=0.003). Meanwhile, 9 main caregivers were mothers in the case group, compared with 14 in the control group. The Logistic regression analysis showed that compared with fathers, mothers as the children’ main caregivers could positively reduce accidental death of children (OR=0.016, 95% CI: 0.000 3-0.997, P=0.049). 【Conclusion】 To decrease the incidence rate and mortality of accidental death of children under the age of five years old, parenting behavior guidance, health examination, and targeted health education should be taken in Maternal and Child Health Care System as a routine work.
ABSTRACT
Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

ABSTRACT
The effects of oenothein B(OEB) on the proliferation, apoptosis, invasion, and migration of breast cancer MCF-7 and MDA-MB-231 cells were investigated by cell culture in vitro, network pharmacology, and molecular docking. In vitro cell experiments revealed that OEB inhibited the proliferation and colony formation ability, and promoted the apoptosis and formation of apoptotic bodies in breast cancer cells, as well as inhibited the invasion and migration of breast cancer cells. The targets of OEB were obtained using SwissTargetPrediction database and breast cancer targets were obtained from GeneCards. The targets of OEB and breast cancer were entered separately in Venny 2.1 software to obtain the Venn diagram of common targets of OEB and breast cancer. The common targets of OEB and breast cancer were input into STRING database to construct a protein-protein interaction(PPI) network, which was entered into Cytoscape 3.7.2 software for network topology analysis. Key targets were screened according to protein association strength, and analyzed for KEGG pathway enrichment. Molecular docking of OEB to key targets using AutoDock software revealed that OEB stably bound to the active pocket of P53, while OEB promoted the expression of P53 protein. MCF-7 and MDA-MB-231 cell viability and migration ability increased after silencing P53, and this change was reversed after treatment with OEB. Therefore, this study showed that OEB inhibited the proliferation, migration, and invasion of breast cancer MCF-7 and MDA-MB-231 cells, and promoted the apoptosis of breast cancer MCF-7 and MDA-MB-231 cells, which may be related to the targeted regulation of P53.

Pancreatic cancer has an insidious onset and lacks effective treatment methods, which is one of the tumors with the worst prognosis, so it is urgent to explore new treatment directions. Metabolic reprogramming is one of the important hallmarks of tumors. Pancreatic cancer cells in the harsh tumor microenvironment have comprehensively increased cholesterol metabolism in order to maintain strong metabolic needs, and cancer associated fibroblasts also provide cancer cells with a large amount of lipids. Cholesterol metabolism reprogramming involves the changes in the synthesis, uptake, esterification and metabolites of cholesterol, which are closely related to the proliferation, invasion, metastasis, drug resistance, and immunosuppression of pancreatic cancer. Inhibition of cholesterol metabolism has obvious anti-tumor effect. In this paper, the important effects and complexity of cholesterol metabolism in pancreatic cancer were comprehensively reviewed from perspectives of risk factors for pancreatic cancer, energy interaction between tumor-related cells, key targets of cholesterol metabolism and its targeted drugs. Cholesterol metabolism has a strict regulation and feedback mechanism, and the effect of single-target drugs in clinical application is not clear. Therefore, multi-target therapy of cholesterol metabolism is a new direction for pancreatic cancer treatment.
