Objective:To investigate the diet, dietary structure and physical activity of 408 early pregnant women in Beijing.Methods:From November 2018 to January 2019, this study selected 408 early pregnant women at the women and children hospital in Beijing by convenience sampling. The diet and physical activity were investigated with the Food Frequency Questionnaires (FFQ) and Denmark Physical Activity Questionnaire. SPSS 22.0 was used to build the database and principal component analysis was used to statistical analysis.Results:Among 408 early pregnant women, the gestational week and pre-pregnancy body mass index (BMI) was (9.77±1.95) weeks and (22.80±3.91) kg/m 2. There were 120 (30.9%) of pregnant women with pre-pregnancy overweight/fat, 136 (33.3%) of them with fasting blood glucose>4.6 mmol/L. Food consumption (cereals and tubers, livestock and poultry meat) all day was lower than recommended nutrient intake of the Chinese Balanced Diet Pagoda. Diet structure of pregnant women mainly included 5 kinds which explained 50.889% of the total cumulative variance; the first diet structures were the livestock and poultry meat, cereals, milk and milk products, tubers; and the vegetables, fried, barbecued, cookies and aquatic product were the second which explained 20.121% of the cumulative variance. Among those pregnant women, the time and energy consumption of resting or mild level of physical activity occupied 87.50% (21/24) and 81.50% (27.00/33.13) of time and energy consumption in 24 hours respectively; the time and energy consumption of medium level of physical activity occupied 7.29% (1.75/24) and 18.50% (16.13/33.13) of time and energy consumption in 24 hours respectively; level E (daily cleaning) accounted for 57.14% (1.00/1.75) and 48.93% (3.00/6.13) of the time and energy consumption of medium level of physical activity; there was no one with level H (aerobics) . Conclusions:Among 408 early pregnant women in Beijing, many pregnant women are with pre-pregnancy overweight/fat; a part of them are with a high level of fasting blood glucose; a part of them select diet outside. In the situation of low level of overall food consumption among early pregnant women, the diet structure mainly includes the livestock and poultry meat, grease, sweetmeats and tubers which leads to much sugar and fat intake. At the same time, early pregnant women have the low level of physical activity. Diet and exercise guide should be carried out to control the weight gain.

Objective:To explore the current status and influencing factors of feeling in control during labor in pregnant women with gestational diabetes mellitus (GDM) .Methods:Totally 200 pregnant women with GDM who underwent vaginal delivery in a Class Ⅲ Graded A maternity hospital in Beijing between from February to July 2018 were selected by convenient sampling. They were required to fill in the general information questionnaire, the Chinese version of Feeling in Control during Labor Scale (FCLS) and State Anxiety Inventory Form (S-AI) 48 hours after delivery to investigate their general information, feeling in control during labor and state anxiety. The factors affecting feeling in control during labor were analyzed, and the data of totally 172 pregnant women were collected.Results:The total score of FCLS in the 172 pregnant women with GDM was (148.00±23.03) , which was in a middle level. Univariate analysis showed that there were statistically significant differences in the scores of FCLS between pregnant women with GDM who had different education levels, occupations, the number of births, whether or not to undergo perineal lateral resection, and whether to use forceps ( P<0.05) . Multivariate analysis revealed that the whether to use forceps, the number of births, antenatal fasting blood glucose, and the level of anxiety during childbirth were the influencing factors for feeling in control of during labor in pregnant women with GDM. Conclusions:The level of feeling in control during labor in pregnant women with GDM in Beijing is higher than that of normal primiparous women. The in control during labor is affected by many factors, and clinical medical staff should take a variety of targeted measures for different populations to enhance their feeling in control during labor, thereby improving the delivery outcome and childbirth satisfaction.

Objective:To construct an evaluation index system for the elderly stressors, so as to provide a basis for comprehensive and effective stressor assessments for the elderly.Methods:With the bio-psycho-social medicine model as the theoretical guide, the first draft of the evaluation index system for the elderly stressors was drawn up through the literature analysis and the semi-structured interview. The Delphi method was used to conduct two rounds of expert consultations to 13 experts. The analytic hierarchy process was used to determine all levels of indicators and their weights.Results:In two rounds of expert consultations, the expert positive coefficients were 86.67% and 100.00% respectively, and the authority coefficients were both 0.889, and the Kendall coordination coefficients were 0.339 and 0.361 respectively ( P<0.05) . The evaluation index system for the elderly stressors included 4 first-level indicators, 12 second-level indicators and 65 third-level indicators. Conclusions:The evaluation index system for the elderly stressors based on the Delphi method is scientific and practical, and can provide a unified standard for the evaluation of the elderly stressors.

Objective To compare different treatment methods for patients with gastric calculi and provide data support for clinical treatment.Methods A total of 197 patients diagnosed with gastric calculi by gastroscopy at the General Hospital of Ningxia Medical University and Cardio-Cerebrovascular Disease Hospital of General Hospital of Ningxia Medical University from July 2013 to January 2024 were enrolled.The study collected general information and other data of the patients,and divided them into groups based on the selected treatment method using a real-world research approach.The subjects were divided into four groups:drug conservative treatment group,endoscopic homemade snare treatment group,disposable snare treatment group,and stone fragmentation treatment group.Statistical analysis was performed using one-way analysis of variance.Results Gastric calculi were more common in men,with an average age of(55.45±14.21).85.3%of the patients had a history of eating persimmon,86.3%had ulcers,and 65.9%were located in the gastric angle.The self-made snare group had the lowest treatment cost,while the stone fragmentation group had the highest.There was no significant difference in the remission time of clinical symptoms among the three endoscopic treatment methods.The self-made snare had the highest patient satisfaction,but the drug combined with carbonated beverage group had the longest remission time of clinical symptoms and the lowest patient satisfaction.The frequency and duration of endoscopic treatment of dark green gastric stones were significantly higher than those of mottled and golden yellow gastric stones.Conclusion When treating patients with gastric stones,it is important to consider the size and color of the stone,as well as the patient's preferences.Patients should be fully informed about their condition and the advantages of different treatments.For patients with larger stones(about 5 cm),endoscopic snare treatment is recommended as the first choice.

Objective To observe regular monitoring in patients with chronic myeloid leukemia (CML) who received tyrosine kinase inhibitor (TKI), and to analyze its influencing factors. Methods A total of 857 patients with CML in Henan Tumor Hospital from October 2012 to October 2016 were collected. Patients were told to receive regular monitoring after receiving TKI treatment, including blood routine, bone marrow, BCR-ABL fusion gene and chromosomes. All patients were divided into good and poor compliance groups according to regular monitoring. Chi-square test was used to compare ABL kinase domain mutations rate and mortality between two groups. TKI species, level of education, duration from diagnosis to treatment, teaching times, sites of follow-up, convenience of transportation, annual income and gender were recorded respectively, and the factors affecting regular monitoring were analyzed by using single and multiple factor analysis. Results There were 390 and 467 patients in good and poor compliance groups respectively. Treatment failure rate was 19.49％ (76/390) and 25.91％ (121/467) in good and poor compliance groups respectively, the mutation rate was 28.95％ (22/76) and 7.44％ (9/121) respectively. The difference of ABL kinase domain mutation in patients with treatment failure of both groups was statistically significant (χ 2 =16.287, P < 0.01). The mortality was 0.77％ (3/390) in good compliance group, and 2.78％ (13/467) in poor compliance group, and the difference was statistically significant (χ 2 = 4.543, P = 0.033). The single factors analysis showed that TKI species, level of education, duration from diagnosis to treatment, teaching times, sites of follow-up, convenience of traffic and annual income were related with regular monitoring (all P < 0.05). Multiple-factor analysis showed that inconvenient transportation (β = 1.56, 95％ CI 1.74-3.74, P = 0.014), low education level (β = 1.67, 95％ CI 0.81-3.12, P = 0.041) and low income (β = 2.87, 95％ CI 1.31-4.51, 95％CI 1.74-3.74, P = 0.011) were independent factors for poor compliance in regular monitoring. In the result detection, 56 fusion genes fluctuated. Conclusions CML patients who received regular monitoring have a low treatment failure rate and mortality. Inconvenient transportation, low education level and low outcome are independent risk factors for regular monitoring. The single monitoring result can not prompt treatment effect, and thus it needs to review and monitor for many times.

Objective To study the effect of cobalt-60 gamma-ray (⁶⁰Co-γ) radiation on the structure of Nialamide, compare the anti-inflammatory activity of irradiation products, and explore the mechanism of action. Methods After ⁶⁰Co-γ irradiation of nialamide at a dose of 50 kGy, five known compounds were obtained (2-6). The viability of RAW 264.7 (mouse mononuclear macrophage leukemia) cells treated with these compounds was determined by CCK-8 assay. The secretion of interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), and prostaglandin E2 (PGE₂) and the content of nitric oxide (NO) were measured using enzyme-linked immunosorbent assay and Griess method. The production of reactive oxygen species (ROS) was detected using DCFH-DA fluorescent probe. The expression levels of cell-induced nitric oxide synthase (iNOS), cyclooxygenase (COX-2), nuclear transcription factor-κB (NF-κB), and IκB were detected using Western blot. Results The products of nialamide after irradiation did not significantly affect RAW264.7 cell viability (P > 0.05) but showed a strong anti-inflammatory effect (P < 0.01). Compared with nialamide, compounds 2, 3, 4, 6 significantly reduced NO content in LPS-induced RAW 264.7 cells (P < 0.01), and compound 4 had the most significant effect. Moreover, compound 4 significantly reduced the content of IL-6, TNF-α, PGE₂, and ROS (P < 0.05) as well as the expression of iNOS, COX-2, NF-κB, and IκB (P < 0.05) in LPS-induced RAW 264.7 cells. Conclusion The chemical structure of nialamide is changed after irradiation with ⁶⁰Co-γ, and its product compound 4 shows strong anti-inflammatory activity, which may be related to inhibiting the activation of NF-κB signaling pathway and reducing the release of inflammatory factors. Radiation technology can provide new insights into the changes of molecular structures and physiological properties of natural products.

ObjectiveTo clarify the intervention effect of Osteoking （OK） in rats with myofascial pain syndrome （MPS） and preliminarily explore the pharmacological mechanism of OK in relieving chronic pain from the perspective of anti-inflammatory disease. MethodThe 60 SD rats were divided into normal group， model group， low， medium， and high dose OK groups （0.66， 1.31， 2.63 mL·kg^-1）， and positive celecoxib group （21 mg·kg^-1）. The MPS rat model was established by beating combined with the centrifugal exercise method， and the OK and celecoxib were given at the same time. SMALGO paw pressure pain manometer detected the shock pain point tenderness threshold of rats， and the Von-Frey needle and acetone stimulation method detected the mechanical hyperalgesia threshold and cold hyperalgesia stimulation response respectively. Eight weeks and 10 weeks after modeling， the spontaneous discharge state and convulsion response of MPS rats were determined by electromyograph （EMG） instrument. The gait changes of MPS rats were detected using a CatWalk gait analyzer. The expression levels of interleukin-1 β （IL-1β）， tumor necrosis factor-α （TNF-α）， substance P （SP）， and bradykinin （BK） were measured by enzyme-linked immunosorbent assay （ELISA）. The protein expression levels of nuclear transcription factor-κB （NF-κB） inhibiting protein α （IκBα）， phosphorylates （p）- IκBα， NF-κB p65， and p-NF-κB p65 were detected in MPS rats by Western blot. The positive expression of p-NF-κB p65 was detected by immunofluorescence. ResultCompared with the normal group， the model group shows 100% positive rates for EMG signal and local convulsions response at both the 8th and 10th weeks. The tenderness threshold and mechanical hyperalgesia threshold are significantly reduced. Cold hyperalgesia score is significantly increased， and gait is abnormal. The expression levels of serum and trigger points IL-1β， TNF-α， SP， BK， p-IκBα， and p-NF-κB p65， as well as the positive expression intensity of p-NF-κB p65 are significantly increased （P<0.01）. Compared with the model group， the positive rate of EMG detection and local convulsion response is significantly reduced in the medium and high dose OK groups （P<0.05）. The tenderness threshold and mechanical hyperalgesia threshold increase significantly in the medium and high dose OK groups， and the cold hyperalgesia score is significantly reduced in the high dose OK group （P<0.01）. The standing time， swing time， and walking period are significantly increased. The swing speed， maximum contact area， and maximum contact intensity are significantly decreased in the high dose OK group （P<0.05）. Moreover， the protein expression levels of p-IκBα/IκBα and p-NF-κB p65/NF-κB p65 are significantly reduced in the medium and high dose OK groups （P<0.05，P<0.01）. The positive expression intensity of p-NF-κB p65 is significantly decreased in the high dose OK group （P<0.01）. ConclusionThe mechanism of OK in relieving the pain in trigger points of MPS and improving gait abnormalities is related to the downregulation of the NF-κB p65 inflammatory signaling pathway to reduce the expression of inflammatory factors and pain mediators in blood and trigger point tissue.
