ABSTRACT

We investigated the effects of decursin on the proliferation, apoptosis, and migration of colorectal cancer HT29 and HCT116 cells through the phosphatidylinositol 3-kinase(PI3K)/serine-threonine kinase(Akt) pathway. Decursin(10, 30, 60, and 90 μmol·L~(-1)) was used to treat HT29 and HCT116 cells. The survival, colony formation ability, proliferation, apoptosis, wound hea-ling area, and migration of the HT29 and HCT116 cells exposed to decursin were examined by cell counting kit-8(CCK8), cloning formation experiments, Ki67 immunofluorescence staining, flow cytometry, wound healing assay, and Transwell assay, respectively. Western blot was employed to determine the expression levels of epithelial cadherin(E-cadherin), neural cadherin(N-cadherin), vimentin, B-cell lymphoma/leukemia-2(Bcl-2), Bcl-2-associated X protein(Bax), tumor suppressor protein p53, PI3K, and Akt. Compared with the control group, decursin significantly inhibited the proliferation and colony number and promoted the apoptosis of HT29 and HCT116 cells, and it significantly down-regulated the expression of Bcl-2 and up-regulated the expression of Bax. Decursin inhibited the wound healing and migration of the cells, significantly down-regulated the expression of N-cadherin and vimentin, and up-regulated the expression of E-cadherin. In addition, it significantly down-regulated the expression of PI3K and Akt and up-regulated that of p53. In summary, decursin may regulate epithelial-mesenchymal transition(EMT) via the PI3K/Akt signaling pathway, thereby affecting the proliferation, apoptosis, and migration of colorectal cancer cells.

ABSTRACT

AIM: To analyze the effects of aromatase inhibitors(AIs)on the ocular surface microenvironment of the users.METHODS: A cross-sectional observational study was conducted. The study included postmenopausal women who received AIs treatment at galactophore department of our hospital from November 2022 to May 2023. Participants were divided into two groups based on the mechanism of AIs: the steroidal group and the non-steroidal group. The control group consisted of age-matched women who underwent occupational health examinations. All participants completed the ocular surface disease index(OSDI)questionnaire and underwent detailed ophthalmic examinations, including best-corrected visual acuity, intraocular pressure, axial length, corneal curvature, radius of curvature of curved lacrimal river surface, tear osmolarity, tear film break-up time, corneal fluorescein staining score, Schirmer Ⅰ test, and meibomian gland infrared score.RESULTS: There were no statistically significant differences in age, best-corrected visual acuity, intraocular pressure, axial length, and corneal curvature between control group and steroidal and non-steroidal group(P>0.05). The duration of drug treatment between the steroidal group and the non-steroidal group also showed no statistically significant difference(P>0.05). However, statistically significant differences were observed between the control group and the steroidal and non-steroidal group in OSDI scores, radius of curvature of curved lacrimal river surface, tear osmolarity, tear film break-up time, corneal fluorescein staining score, Schirmer Ⅰ test, and meibomian gland infrared score(P<0.05). The Schirmer Ⅰ test also showed statistically significant differences between the steroidal group and the non-steroidal group(P<0.05), while other data showed no statistically significant differences(P>0.05).CONCLUSION: Postmenopausal patients receiving AIs treatment experienced significant changes in the ocular microenvironment, with both decreased tear secretion and excessive tear evaporation contributing to the occurrence of dry eye. Notably, patients receiving non-steroidal AIs treatment showed a more significant reduction in main lacrimal gland secretion.

ABSTRACT

Objective: To understand the social security situation of current cases of pneumoconiosis in non-coal mine industries in Jiangsu Province, and to provide reference for the treatment and security work of pneumoconiosis patients. Methods: From January to October 2020, a follow-up survey was conducted on 4038 cases of pneumoconiosis in non-coal mine industries of the province from October 1949 to December 2019. The age, type of pneumoconiosis, industry type, and social security status of the patients were collected. Namely, work-related injury insurance, employer compensation, basic medical insurance for urban and rural residents, major illness insurance, etc. SPSS 19.0 was used for statistical description and analysis. Results: The cases of pneumoconiosis in non-coal mine industries in Jiangsu Province ranged in age from 36 to 105 (70.78±8.43) years old, and had been exposed to dust for 1 to 55 (19.27±9.29) years. Silicosis was the main form (3875 cases, 95.96%), and non-metallic mining and dressing industry was the main form (2618 cases, 64.83%). A total of 3991 cases (98.84%) of pneumoconiosis patients enjoyed social security, most of them were urban and rural residents with basic medical insurance (3624 cases, 89.75%), but there were still 47 patients without any social security. 15 cases (0.37%) enjoyed the subsistence allowance, with the monthly allowance amount ranging from 104 to 3960 yuan, with the average amount of 954.87 yuan/month. Conclusion: In Jiangsu Province, the proportion of pneumoconiosis patients in non-coal mine industries enjoying social security is relatively high, but there are still patients who do not enjoy any social security, and the difference in the amount of subsistence allowance is slightly larger. It is necessary to further improve the medical security of pneumoconiosis patients and improve their quality of life.

ABSTRACT

The toxic pathogen theory, an important part of the theories of traditional Chinese medicine(TCM), began in the Qin and Han dynasties, formed in the Jin, Sui, Tang, and Song dynasties, developed rapidly in the Ming and Qing dynasties, and conti-nued to develop in contemporary times based on the achievements of its predecessors. The continuous exploration, practice, and inheri-tance of many medical practitioners over the generations have facilitated the enrichment of its connotation. The toxic pathogen is violent, fierce, dangerous, prolonged, rapid in transmission, easy to hurt the internal organs, hidden, and latent, with many changes, and it is closely related to the development of tumor diseases. TCM has a history of thousands of years in the prevention and treatment of tumor diseases. It is gradually realized that the etiology of tumor is mainly attributed to the deficiency of healthy Qi and excess of to-xic pathogen, and the struggle between healthy Qi and toxic pathogen runs through the whole course of tumor, with the deficiency of healthy Qi as the prerequisite and the invasion of toxic pathogen as the root of the occurrence. The toxic pathogen has a strong carcinogenic effect and is involved in the whole process of tumor development, which is closely related to the malignant behaviors of tumors, including proliferation, invasion, and metastasis. This study discussed the historical origin and modern interpretation of the toxic pathogen theory in the prevention and treatment of tumors, with aims of sorting out the theoretical system based on the toxic pathogen theory in the treatment of tumor diseases, and illustrating the importance of the toxic pathogen theory in the treatment of tumors in the context of modern research on pharmacological mechanisms and the development and marketing of relevant anti-tumor Chinese medicinal preparations.

ABSTRACT

The chemical constituents in stem leaf, root, and flower of Ixeris sonchifolia were identified by the ultra performance li-quid chromatography coupled with linear ion trap quadrupole-orbitrap mass spectrometry(UPLC-LTQ-Orbitrap-MS~n). The separation was performed on an Acquity UPLC BEH C_(18) column(2.1 mm×100 mm, 1.7 μm) with a mobile phase of water(containing 0.1% formic acid, A)-acetonitrile(B) with gradient elution. With electrospray ionization source, the data of 70% methanol extract from stem leaf, root and flower of I. sonchifolia were collected by high-resolution full-scan Fourier transform spectroscopy, data dependent acquisition, precursor ion scan, and selected ion monitoring in the negative and positive ion modes. The compounds were identified based on accurate molecular weight, retention time, fragment ions, comparison with reference standard, Clog P and references. A total of 131 compounds were identified from the 70% methanol extract of I. sonchifolia, including nucleosides, flavonoids, organic acids, terpenoids, and phenylpropanoids, and 119, 110, and 126 compounds were identified from the stem leaf, root and flower of I. sonchifolia, respectively. In addition, isorhamnetin, isorhamnetin-7-O-sambubioside and caffeylshikimic acid were discovered from I. sonchifolia for the first time. This study comprehensively analyzed and compared the chemical constituents in different parts of I. sonchifolia, which facilitated the discovery of effective substances and the development and application of medicinal material resources of I. sonchifolia.

ABSTRACT

Objective: To investigate the risk factors of childhood systemic lupus erythematosus (SLE) with thyroid dysfunction and to explore the relationship between thyroid hormone and kidney injury of lupus nephritis (LN). Methods: In this retrospective study, 253 patients who were diagnosed with childhood SLE and hospitalized in the First Affiliated Hospital of Zhengzhou University from January 2019 to January 2021 were enrolled in the case group, and 70 healthy children were the control cases. The patients in the case group were divided into the normal thyroid group and the thyroid dysfunction group. Independent t-test, χ2 test, and Mann-Whitney U test were used for comparison between the groups, Logistic regression analysis was used for multivariate analysis, and Spearman correlation. Results: A total of 253 patients, there were 44 males and 209 females in the case group, and the age of onset was 14 (12, 16) years; a total of 70 patients, 24 males and 46 females were in the control group, and the age of onset was 13 (10, 13) years. The incidence of thyroid dysfunction in the case group was higher than that in the control group (48.2% (122/253) vs. 8.6% (6/70), χ²=36.03, P<0.05). Of the 131 patients, there were 17 males and 114 females in the normal thyroid group, and the age of onset was 14 (12, 16) years. Of the 122 patients in the thyroid dysfunction group, 28 males and 94 females were in the thyroid dysfunction group, and the age of onset was 14 (12, 16) years. Of the 122 had thyroid dysfunction, including 51 cases (41.8%) with euthyroid sick syndrome, 25 cases (20.5%) with subclinical hypothyroidism, 18 cases (14.8%) patients with sub-hyperthyroidism, 12 cases (9.8%) with hypothyroidism, 10 cases (8.2%) with Hashimoto's thyroiditis, 4 cases (3.3%) with hyperthyroidism, and 2 cases (1.6%) with Graves disease. Compared to patients with normal thyroid function, the serum level of triglyceride, total cholesterol, urine white blood cell, urine red blood cell, 24 h urine protein, D-dimer, and fibrinogen, ferritin and systemic lupus erythematosus disease activity Index-2000 (SLEDAI-2K) score were higher in patients with thyroid dysfunction (Z=3.07, 3.07, 2.48, 3.16, 2.40, 3.99, 2.68, 2.55, 2.80, all P<0.05), while the serum level of free thyroxine and C3 were lower in thyroid disfunction patients (10.6 (9.1, 12.7) vs. 11.3 (10.0, 12.9) pmol/L, and 0.46 (0.27, 0.74) vs. 0.57 (0.37, 0.82) g/L, Z=2.18, 2.42, both P<0.05). The higher level of triglyceride and D-dimer were the independent risk factors for childhood SLE with thyroid dysfunction (OR=1.40 and 1.35, 95%CI 1.03-1.89 and 1.00-1.81, respectively, both P<0.05). There were 161 patients with LN in the case group, all of which were conducted with renal biopsies, including 11 cases (6.8%) with types Ⅰ LN, 11 cases (6.8%) with typesⅡLN, 31 cases (19.3%) with types Ⅲ LN, 92 cases (57.1%) with types Ⅳ LN, and 16 cases (9.9%) with types Ⅴ LN. There were significant differences in the level of free triiodothyronine and thyroid stimulating hormone among different types of kidney pathology (both P<0.05); compared with types I LN, the serum level of free triiodothyronine was lower in types Ⅳ LN (3.4 (2.8, 3.9) vs. 4.3 (3.7, 5.5) pmol/L, Z=3.75, P<0.05). The serum level of free triiodothyronine was negatively correlated with the acute activity index score of lupus nephritis (r=-0.228, P<0.05), while the serum level of thyroid stimulating hormone was positively correlated with the renal pathological acute activity index score of lupus nephritis (r=0.257, P<0.05). Conclusions: There is a high incidence of thyroid dysfunction in childhood SLE patients. The higher SLEDAI and more severe renal damage were found in SLE patients with thyroid dysfunction compared to these with normal thyroid functions. The risk factors of childhood SLE with thyroid dysfunction are the higher level of triglyceride and D-dimer. The serum level of thyroid hormone is possibly related to the kidney injury of LN.

ABSTRACT

OBJECTIVE@#To observe the effect of acupuncture at Weizhong (BL 40) with deqi on bladder urination function.@*METHODS@#A total of 60 healthy subjects were randomized into an observation group and a control group, 30 subjects in each group. Under the guidance of ultrasound, acupuncture was applied Weizhong (BL 40) on both sides. In the observation group, the needling depth was reached to the tibial nerve, and lifting-thrusting twirling method was used to induce deqi. In the control group, the needling depth was reached to the superficial fascia, and no manipulation was operated to induce deqi. The needles were retained for 10 min and acupuncture was given once in both groups. The bilateral ureteral ejection frequency and volume of the bladder were observed by ultrasound before and after acupuncture, and the score of clinical evaluation scale of deqi sensation was observed in both groups.@*RESULTS@#After acupuncture, the frequency of bilateral ureteral ejection in the observation group and the bladder volume in the two groups were increased compared before acupuncture (P<0.05), and the frequency of bilateral ureteral ejection, bladder volume and score of clinical evaluation scale of deqi sensation in the observation group were higher than those in the control group (P<0.05, P<0.01).@*CONCLUSION@#Acupuncture at Weizhong (BL 40) with deqi improves the bladder urination function. Ultrasound visualization improves the standardization and safety of acupuncture, intuitively evaluates the acupuncture effect, and provides an objective basis for the correlation between meridian points specificity and zang-fu organs.

ABSTRACT

Objective: To evaluate the household secondary attack rates of the SARS-CoV-2 Delta variant and the associated factors. Methods: A COVID-19 outbreak caused by the Delta variant occurred in Nanjing in July 2021. A total of 235 cases with current addresses in Nanjing were reported from 171 households. The subjects in this study were selected from household close contact(s) of infected cases. The information on household index cases and their contacts were collected, and the household secondary attack rate (HSAR) and the risk factors were analyzed by the multi-factor logistic regression model. Results: A total of 234 cases of household close contacts and 64 household secondary cases were reported from 103 households, and the HSAR was 27.4% (64/234, 95%CI:22.0% to 33.4%). The proportions of household size for 2 to 3, 4 to 5, and 6 to 9 were 64.1% (66), 26.2% (27) and 9.7% (10), respectively. A total of 35 cases of household cluster outbreaks were reported (35/103, 34.0%). The number of the first case in the household (FCH) was 103 and males accounted for 27.2% (28 cases), with the median age (Q1, Q3) of 49 (9, 56). The number of household close contacts was 234 and males accounted for 59.0% (138 cases), with the median age (Q1, Q3) of 42 (20, 55) and the median exposure period (Q1, Q3) of 3 (1, 3) days. The multi-factor logistic regression model showed that the higher HSAR was observed in the FCH with the features of airport staff (OR=2.913, 95%CI:1.469-5.774), detection from home quarantine screening (OR=6.795, 95%CI:1.761-26.219) and detection from mass screening (OR=4.239, 95%CI:1.098-16.368). Meanwhile, higher HSAR was observed in cases with longer household exposure (OR=1.221, 95%CI:1.040-1.432), non-vaccination (OR=2.963, 95%CI:1.288-6.813) and incomplete vaccinations (OR=2.842, 95%CI:0.925-8.731). Conclusion: The generation interval of the Delta variant is shortened, and the ability of transmission within the household is enhanced. In the outbreak in Nanjing, the associated factors of HSAR are occupation, detection route, vaccination and exposure period.

ABSTRACT

Bisphenol A is a common environmental factor and endocrine disruptor that exerts a negative impact on male reproductive ability. By exploring bisphenol A-induced testicular cell death using the Institute of Cancer Research (ICR) mouse model, we found that a ferroptosis phenomenon may exist. Mice were divided into six groups and administered different doses of bisphenol A via intragastric gavage once daily for 45 consecutive days. Serum was then collected to determine the levels of superoxide dismutase and malondialdehyde. Epididymal sperm was also collected for semen analysis, and testicular tissue was collected for ferritin content determination, electron microscope observation of mitochondrial morphology, immunohistochemistry, real-time quantitative polymerase chain reaction, and western blot analysis. Exposure to bisphenol A was found to decrease sperm quality and cause oxidative damage, iron accumulation, and mitochondrial damage in the testes of mice. In addition, bisphenol A was confirmed to affect the expression of the ferroptosis-related genes, glutathione peroxidase 4 (GPX4), ferritin heavy chain 1 (FTH1), cyclooxygenase 2 (COX2), and acyl-CoA synthetase 4 (ACSL4) in mouse testicular tissues. Accordingly, we speculate that bisphenol A induces oxidative stress, which leads to the ferroptosis of testicular cells. Overall, the inhibition of ferroptosis may be a potential strategy to reduce male reproductive toxicity caused by bisphenol A.

ABSTRACT

OBJECTIVE@#To explore the effective method of applying Chinese medicine manipulative repositioning Kirschner wire fixation for minimally invasive treatment of fractures of the neck of the fifth metacarpal.@*METHODS@#From January 2018 to November 2021, 90 patients with closed fractures of the neck of the fifth metacarpal bone were treated minimally invasively with closed repositioning Kirschner wires, all fractures AO type was type A. All patients were divided into three groups according to the mode of internal fixation involving 30 cases in the crossed Kirschner's wire group, 30 cases in the transverse Kirschner's wire group, 30 patients in the intramedullary Kirschner's wire group. By comparison, gender, age, disease duration, and preoperative neck-stem angle were not significant. The postoperative fifth metacarpal neck-stem angles, postoperative fifth metacarpophalangeal joint flexion mobility and fifth metacarpophalangeal joint extension hyperextension angles were compared among three groups. The overall clinical efficacy was evaluated according to the patient outcomes of surgery-hand/arm(POS-Hand/Arm) scoring system.@*RESULTS@#All patients had 12-month follow-up and achieved bony union without malunion. There was no significant difference in the 5th metacarpal neck-stem angle, the fifth metacarpophalangeal joint flexion angle and the fifth metacarpophalangeal joint extension hyperextension angles among three groups at 12 months after surgery(P>0.05). There was no significant difference in physical activity and symptom scores in POS-Hand/Arm scores at 12 months after surgery(P>0.05), psychological status and aesthetic score among three groups(P<0.05) and between cross and transverse Kirschner wire groups(P>0.05). The three POS-Hand/Arm total scores were statistically different(P<0.05), between the crossed and transverse(P>0.05), and the intramedullary group had the highest POS-Hand/Arm scores.@*CONCLUSION@#All three techniques of Kristener's wire fixation could achieve minimally invasive treatment, and patients have need for cosmetic and early activity, and the author recommend minimally invasive intramedullary fixation with manipulative repositioned Kristen wires as the preferred procedure.

ABSTRACT

Prunus mume is an edible and medicinal material, and Mume Fructus is its processed product, which was first recorded in Shennong's Classic of Materia Medica(Shen Nong Ben Cao Jing). It is an effective drug for stopping diarrhea with astringents and promoting fluid production to quiet ascaris. By consulting the ancient herbal works of the past dynasties, modern codes, and other rela-ted literature, this paper sorted out the medicinal evolution of Mume Fructus, examined the ancient efficacy of Mume Fructus and the main indications, and summarized the inclusion of Mume Fructus in national and provincial standards. It is recorded in the ancient herbal works of the past dynasties that Mume Fructus can be processed by various methods such as roasting, stir-frying or micro-frying, stir-frying with charcoal, single steaming, steaming with wine, and steaming after soaking in wine or vinegar, and prepared into pills, powders, and ointments, which are used in the treatment of fatigue, diabetes, malaria, dysentery, ascariasis, and other diseases. Mume Fructus has been included in nine editions of Chinese Pharmacopoeia and 19 provincial and municipal preparation specifications. The processing method of Mume Fructus is determined, namely, clean P. mume should be softened by moistening in water or steaming and pitted. By reviewing the effects of processing on its chemical composition, pharmacological effects, and its modern clinical application, this paper identified the following issues. The ancient application methods of Mume Fructus are diverse but less commonly used in modern times, there is a lack of standardized research on the processing, and the research on the changes caused by the difference in Mume Fructus before and after processing is not deep. Therefore, it is necessary to further investigate the change pattern of its chemical composition before and after processing and its correlation between its medicinal activity to standardize the processing technology and provide a solid basis for the use of Mume Fructus in parts and its quality control.

ABSTRACT

Objective:To investigate the effect of ultrasound monitoring of inferior vena cava collapse index (IVC-CI) guiding fluid replacement on circulation in elderly patients during induction of general anesthesia.Methods:A total of 71 elderly patients who underwent elective surgery under general anesthesia and tracheal intubation at Hunan Provincial People′s Hospital from April 2021 to September 2022 were randomly divided into control group (35 cases) and observation group (36 cases) using a random number table method. Before anesthesia, both groups of patients underwent IVC ultrasound examination and calculated the IVC-CI value. For patients with IVC-CI≥40%, the observation group was given 8 ml/kg of crystal solution before anesthesia induction, while the control group was not treated. The incidence of hypotension, the use of vasoactive drugs, and the total infusion volume from anesthesia induction to skin incision were recorded in two groups. Mean arterial blood pressure (MBP), heart rate (HR), oxygen saturation (SpO 2), cardiac index (CI), and cardiac volume variability (SVV) before anesthesia (T 0), 5 min after induction (T 1), 1 min after tracheal intubation (T 2), 5 min after tracheal intubation (T 3), 10 min after tracheal intubation (T 4), and 1 min before skin incision (T 5) were recorded and compared between the two groups. Results:The incidence of hypotension (27.8% vs 60.0%) and utilization rate of vasoactive drugs (25.0% vs 48.6%) in the observation group were lower than those in the control group, and the total infusion volume during anesthesia induction was higher than that in the control group, with statistical significance (all P<0.05). SVV, CI and MBP at T 1, T 3, T 4 and T 5 were significantly different from those at T 0 in the control group ( F=3.85, 14.66, 3.96, all P<0.05). SVV, CI and MBP at T 1, T 3, T 4 and T 5 in the observation group were significantly different from those at T 0 ( F=3.51, 13.20, 4.35, all P<0.05). There was no significant difference in SVV, CI, MBP, HR and SpO 2 between 2 groups (all P>0.05). Conclusions:For the elderly patients with preoperative IVC-CI≥40%, pre-filling with 8ml/kg crystal solution before anesthesia induction can significantly reduce the incidence of hypotension and the utilization rate of vasoactive drugs in the elderly patients during anesthesia induction.

ABSTRACT

Objective To investigate the combined effect of noise and hand-transmitted vibration on hearing loss in male noise-exposed workers. Methods A total of 952 male noise-exposed workers from an automobile manufacturing enterprise were selected as the research subjects using judgment sampling method. Occupational epidemiological surveys, assessments of occupational hazards in workplace, and pure-tone audiometry tests were conducted on the research subjects, and they were divided into low-level noise group, low-level combined group, high-level noise group, and high-level combined group according to whether the noise exposure level exceeded the national standard and whether they were jointly exposed to hand-transmitted vibration. The joint effects of noise and hand-transmitted vibration on hearing loss were analyzed. Results The detection rate of hearing loss in 952 noise-exposed workers was 21.7%. The detection rate of hearing loss of four groups, from high to low, was as follows: high-level combined group, high-level noise group, low-level combined group, and low-level noise group (44.9% vs 32.7% vs 12.9% vs 5.7%, P<0.01). The results of multivariate logistic regression analysis showed that the risk of hearing loss in the low-level noise group, the low-level combined group, the high-level noise group and the high-level combined group increased sequentially after adjusting for the confounding factors such as age, education level, smoking, drinking, listening to music with headphones, frequency of wearing noise-blocking earplugs and body mass index. The risk of hearing loss in the high-level noise group was 8.62 times more than that of the low-level noise group (P<0.01). The risk of hearing loss in the low-level noise combined group was 2.50 times more than that of the low-level noise group (P<0.01). The risks of hearing loss in the high-level combined group were 5.76 and 1.67 times more than that of the low-level combined group and the high-level noise group. Conclusion Combined exposure to noise and hand-transmitted vibration can increase the risk of hearing loss in male noise-exposed workers, and the higher the noise intensity, the greater the synergistic effect.

ABSTRACT

@#Transcatheter aortic valve replacement (TAVR) techniques have been rapidly developed in recent years. Current guidelines and studies mainly focus on aortic stenosis patients treated by transfemoral approach, but they are not completely appropriate to patients with isolated aortic regurgitation or other patients who need transapical TAVR (TA-TAVR), which affects the standardized treatment of those patients. Therefore, our team pronounced the operational standards for TA-TAVR, based on fully reviewing the literatures worldwide, combined with the opinions of experts from 15 heart centers with rich experience in carrying out TA-TAVR in China. This standard aims to provide clinicians with standardized diagnosis and treatment principles of TA-TAVR and improve the quality of TA-TAVR in China.

ABSTRACT

Objective:Both type 1 diabetes and type 2 diabetes are associated with abnormal bone metabolism, but they have different pathogenic mechanisms. Sclerostin(SOST), Dickkopf-related protein 1(DKK-1), and irisin are newly discovered factors involved in the regulation of bone metabolism. This study aims to compare the differences in serum levels of SOST, DKK-1, and irisin between patients with type 1 diabetes and type 2 diabetes.Methods:This cross-sectional study included 101 patients with type 1 diabetes who visited the Endocrinology Department of Peking Union Medical College Hospital from 2017 to 2019, as well as 55 patients with type 2 diabetes and 59 individuals with normal glucose tolerance who were confirmed through an oral glucose tolerance test as part of the Beijing Changping Community Type 2 Diabetes Management Program from 2014 to 2015. Enzyme-linked immunosorbent assay(ELISA) was used to measure the levels of SOST, DKK-1, and irisin.Results:There were more female participants than male participants, with an average age of 49 years. The group with type 1 diabetes had a longer duration of illness( P<0.001) and higher HbA 1C levels( P<0.001) compared to the group with type 2 diabetes, and there was no statistical difference in age between the two groups. Both the type 1 diabetes and type 2 diabetes groups had lower levels of serum procollagen type 1 N-terminal propeptide(P1NP) compared to the control group [(8 579±400)pg/mL, (7 268±552)pg/mL vs(10 051±618)pg/mL, P=0.039, P=0.001]; But the β isomer of C-terminal cross-linking telopeptide of type 1 collagen(β-CTX) showed no statistical difference compared to the control group. Patients with type 1 diabetes and type 2 diabetes had higher SOST than controls [(129.7±6.8)pg/mL, (104.8±6.8)pg/mL vs(85.9±5.3)pg/mL, P<0.001, P=0.030], the differences between the type 1 diabetes group and the control group lost statistical significance after adjusting for factors such as fasting blood glucose and lipid levels. There was no significant difference in SOST between type 1 diabetes and type 2 diabetes groups. There was no significant difference in DKK-1 among three groups, but DKK-1 in type 1 diabetes group was lower or tended to be lower than that in type 2 diabetes group. Serum irisin in patients with type 1 diabetes was higher than that in controls and patients with type 2 diabetes[(16.6±0.7)ng/mL vs (9.6±0.6)ng/mL, (9.8±0.6)ng/mL, both P<0.001], but there was no significant difference in irisin level between type 2 diabetes and controls. Conclusions:Patients with both type 1 and type 2 diabetes showed inhibition of the bone formation marker P1NP, while the bone resorption marker β-CTX did not significantly change. SOST levels were elevated or showed an increasing trend in both type 1 and type 2 diabetes patients, which may be related to the inhibition of bone formation. Additionally, type 1 diabetes patients had increased levels of irisin, which may be involved in abnormal bone turnover.

ABSTRACT

This study aims to systematically evaluate the efficacy and safety of Shuxuetong Injection in the treatment of stroke in progressive. Randomized controlled trials of Shuxuetong Injection in the treatment of stroke in progressive were searched from CNKI, Wanfang, VIP, CMB, PubMed and EMbase. After strict literature screening, data extraction and quality evaluation, a total of 22 articles were included for analysis by RevMan 5.3. The Meta-analysis showed that Shuxuetong Injection combined with conventional treatment was superior to the conventional treatment alone in the major outcome indicators including effective rate(RR=1.27, 95%CI[1.20, 1.33], Z=9.18, P<0.000 01), deterioration rate(RR=0.38, 95%CI[0.22, 0.68], Z=3.31, P=0.000 9), NIHSS scores(MD=-3.89, 95%CI[-4.34,-3.43], Z=16.83, P<0.000 01), CSS scores(MD=-5.59, 95%CI[-6.42,-4.76], Z=13.20, P<0.000 01) and activity of daily living scores(MD=12.02, 95%CI[10.31, 13.72], Z=13.83, P<0.000 01), mortality during treatment was not increased(RR=0.40, 95%CI[0.13, 1.26], Z=1.56, P=0.12). Moreover, Shuxuetong Injection combined with conventional treatment further reduced the secondary outcome indicators including fibrinogen(MD=-0.35, 95%CI[-0.58,-0.13], Z=3.09, P=0.002), triglyceride(MD=-0.38, 95%CI[-0.67,-0.10], Z=2.65, P=0.008), low density lipoprotein cholesterol(MD=-0.72, 95%CI[-0.83,-0.61], Z=12.64, P<0.000 01), serum hypersensitive C-reactive protein(MD=-4.41, 95%CI[-6.96,-1.86], Z=3.38, P=0.000 7), and interleukin-6(MD=-5.43, 95%CI[-6.91,-3.96], Z=7.22, P<0.000 01). GRADE evaluation results showed that the major outcome indicators had low quality of evidence. Shuxuetong Injection in the treatment of stroke in progressive can improve the clinical effective rate, reduce the deterioration rate, improve the neurological function and activity of daily living, down-regulate the levels of fibrinogen, triglyceride, low density lipoprotein cholesterol and alleviate the inflammatory response. Although most studies have reported no adverse reactions, there are selective reports. The safety of Shuxuetong Injection needs to be further verified by more high-quality randomized controlled trial.

ABSTRACT

Objective: To explore the mediating effect of job burnout of nursing staff in clinical departments on occupational stress and anxiety, and to provide scientific basis for the formulation of intervention measures to relieve anxiety. Methods: From November 2020 to January 2021, a cross-sectional survey was conducted to investigate the basic situation, occupational stress, job burnout and anxiety of 653 nursing staff in a third class A general hospital in Hebei Province. Spearman rank correlation was used to analyze the relationship between occupational stress, job burnout and anxiety, stepwise regression and mediating effect model were used to verify the mediating effect of job burnout on the relationship between occupational stress and anxiety. Results: 551 valid questionnaires were collected with effective recovery of 84.38%. The incidence of high occupational stress was 68.06% (375/551) , the incidence of job burnout was 63.70% (351/551) [high, moderate and moderate were 11.07% (61/551) and 52.63% (290/551) respectively], and the incidence of anxiety was 55.72% (307/551) [mild, moderate and severe were 38.11% (210/551) , 8.53% (47/551) and 9.08% (50/551) respectively]. Occupational stress was positively correlated with job burnout and anxiety (r=0.545, 0.479) , and job burnout was positively correlated with anxiety (r=0.542, P<0.05) . The mediating effect analysis showed that occupational stress had a statistically significant effect on anxiety (c=0.509, P<0.001) , and the mediating effect of job burnout on the relationship between occupational stress and anxiety accounted for 44.99% of the total effect. Conclusion: The anxiety level of the nursing staff in this third-class A general hospital was relatively high. Job burnout has a mediating effect between occupational stress and anxiety, and anxiety of nursing staff can be alleviated by reducing occupational stress or job burnout.

ABSTRACT

Objective: To analyze the work indicators of China Comprehensive AIDS Response Program (China CARES) and provide reference for future work of the program. Methods: The scores of each indicator were calculated, and different scores among different types of program areas were compared. The M(Q1,Q3) was used to describe the score of each indicator. The entropy weight method was used to calculate the composite score of each indicator and the composite score was translated into a 100-point system and compared among indicators. Results: In terms of the first-level indicators, organizational leadership and management (96.0 points), publicity and education (94.0 points), and innovative strategies and measures (98.0 points) got relatively high scores; while comprehensive social governance of AIDS prevention (72.0 points) was with the lowest score. The scores of publicity and education and comprehensive intervention in county-level program areas were significantly lower than those in urban areas. For secondary indicators, the indicator with relatively lower scores included "condom use among female sex workers last time" (70.0 points)", "at least one local key population has an increase in the number of people receiving HIV testing compared with the previous year" (70.0 points)", "colleges and occupational schools set up AIDS-related self-service facilities" (65.0 points), "HIV testing among the arrested people suspected of prostitution, adultery, drug users and traffickers" (55.0 points) and "condom use among men who have sex with men during last episode" (50.0 points). The "indicator 3 comprehensive intervention" contributed most to the evaluation, while "indicator 7 innovation strategies and measures" played a minor role in the evaluation results. Conclusions: The overall situation of AIDS Response Program in 2020 was good, but the progress in different word areas was not yet balanced. The two areas of comprehensive intervention and comprehensive social governance of AIDS prevention should be strengthened. It is also suggested that relevant indicators be adjusted appropriately to improve evaluation indicators system and comprehensively promote the program.
