Objective: To investigate the association between muscle mass and quality of life in adults in Shaanxi adults. Methods: The data in this analysis were part of the baseline survey of the Regional Ethnic Cohort Study in Northwest China from June 2018 to May 2019 in Shaanxi Province. The participants' quality of life, including physical component summary (PCS) and mental component summary (MCS), was assessed by the 12-Item Short Form Survey, and the Body Fat Determination System measured muscle mass. A logistic regression model with adjustment for confounding factors was established to analyze the association between muscle mass and quality of life in different genders. Further, sensitivity and subgroup analyses were conducted to explore its stability. Finally, a restricted cubic spline was employed to investigate the dose-response relationship between muscle mass and quality of life in different genders. Results: A total of 20 595 participants were included, with an average age of 55.0, and 33.4% were male. After controlling for potential confounders, compared with the Q₁ group, the risk of low PCS was reduced by 20.6% (OR=0.794, 95%CI: 0.681-0.925) and the risk of low MCS was lower reduced by 20.1% (OR=0.799, 95%CI: 0.689-0.926) in female Q₅ groups. Compared with the Q₁ group, the risk of low PCS was reduced by 24.4% (OR=0.756, 95%CI: 0.644-0.888) in the male Q₂ group. However, no significant association between muscle mass and MCS in males has been found. In females, restricted cubic spline analysis showed a significant linear dose-response relationship between muscle mass and PCS and MCS. Conclusions: There is a positive association between muscle mass and quality of life in Shaanxi adults, especially females. With the increase in muscle mass, the physical and mental functions of the population continue to improve.

Objective To explore the expression and distribution characteristics of vascular endothelial growth factor-B(VEGF-B) in diencephalon and brainstem of Yak’s brain tissues, and to investigate the associations between its expression and hypoxia adaptation. Methods Five healthy yaks were selected, and the brain tissues were divided and collected according to the gross anatomical structure of the brain, including pituitary, thalamus, hypothalamus, oblongata and pons. The characteristics of expression and location of VEGF-B in different regions of Yak’s brain tissues were detected by Real-time PCR, Western blotting and immunohistochemical techniques. Results The results showed that the highest expression level of VEGF-B mRNA of yak brain tissue was in the pituitary, and the content was significantly higher than that found in other parts of the brain(P<0. 05). Following the expressions were in the hypothalamus, thalamus and medulla oblongata, while the lowest expression level was in pons. The expression level of VEGF-B protein in Yak’s brain tissue was similar to the mRNA expression level except that the thalamus was higher than that of hypothalamus. The result of immunohistochemistry showed that VEGF-B protein-positive substances were mainly distributed in the cytoplasm of various types of cells. Among them, the positive staining of VEGF-B was mainly concentrated in eosinophils of pituitary. The positive staining of VEGF-B was mainly concentrated in pleomorphic cells of thalamus and hypothalamus. The distribution of VEGF-B protein-positive substances were mainly focused in nerve cell body of medulla oblongata and pons. Conclusion VEGF-B protein is expressed in both diencephalon and brainstem of yak, which may be closely related to its functions of anti-apoptosis, "survival factor" and angiogenesis. However, the specific mechanism of its neuroprotective effect on Yak brain under hypoxic environment needs to be further studied. The difference of expression in different regions may be related to the tissue specificity and function in different regions of the brain.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

OBJECTIVE: To explore the synergistic immunomodulatory mechanism of interferon alpha-1b, interleukin-2 and thalidomide (ITI) regimen on patients with acute myeloid leukemia (AML). METHODS: Sixty eight untreated de novo or relapsed or refractory or maintenance therapy patients with AML admitted in the Affiliated Cancer Hospital of Zhengzhou University and the other 11 medical units from March 2016 to May 2019 were treated with ITI regimen. Peripheral blood specimen per patient was collected into EDTA-K3 anticoagulation vacuum tube before the administration of ITI and 3 months after the treatment; peripheral blood lymphocyte subsets and perforin and Granzyme B expression were analyzed by using flow cytometry; the levels of VEGF, IFN-γ, TNF-α and IL-6 in the plasma were detected by using a cytometric bead array. Thirty-five healthy subjects from the hospital physical examination centre were selected as normal controls. RESULTS: The ratio of CD4 CONCLUSION The ITI regimen can raise the ratio of CD4

In this study, the evidence mapping methodology was used to systematically retrieve and sort out the clinical research evidence of Chinese patent medicines in the treatment of tension-type headache(TTH), and to understand the distribution of evidence in this field and the basis and quality of evidence. Chinese and English articles on the 28 Chinese patent medicines for TTH, which were recorded in National Essential Medicines List(2018), Medicine Catalogue for National Basic Medical Insurance, Work Injury Insurance, and Maternity Insurance(2020), and Chinese Pharmacopoeia(2020), were retrieved from China National Knowledge Infrastructure(CNKI), Wanfang, VIP, China Biology Medicine disc(CBMdisc), PubMed, EMbase, and Cochrane Library from the establishment to June 2021, followed by descriptive analysis. Then, tables and bubble charts were plotted to analyze the distribution characteristics of evidence. A total of 129 eligible articles were yielded: 126 randomized/non-randomized controlled trials, and 3 systematic reviews. The functions, indications, and composition of the 28 medicines, as well as the proportion of related articles, publication trends, intervention measures, and outcome indicators were compared and analyzed. The results showed that the 28 Chinese patent medicines, composed of 128 Chinese medicinals, can be classified into six categories in terms of function: reinforcing healthy Qi, tranquilizing mind, dispelling stasis, regulating Qi, treating wind, and resuscitating. There are ongoing efforts to study the treatment of TTH with Chinese patent medicine in China, despite of little evidence. The clinical positioning of Chinese patent medicine for TTH is not clear, and clinical research fails to highlight the advantages of Chinese medicine. In addition, the outcome indicators have not been standardized and unified, and there is a lack of evidence on the long-term efficacy of Chinese patent medicine for TTH. This study is the first exploratory application of evidence maps to compare the characteristics and clinical research progress of 28 Chinese patent medicines for TTH, which can provide a reference for research on the optimization of Chinese medicine strategies for TTH.

OBJECTIVE: To compare therapeutic effects of single locking plates and locking plates with suture anchors in treating type Neer IIb distal clavicle fractures. METHODS: From January 2013 to January 2015, 40 distal clavicle fractures patients with Neer IIb were treated by retrospectively analyzed and divided into single locking plates (control group) and locking plates with suture anchors(observation group) according to methods of operation. There were 20 patients in control group treated by single locking plates, including 16 males and 4 females aged from 26 to 64 years old with an average of(40.60±12.64) years old; while there were 20 patients in observation group treated by locking plates with suture anchors, including 15 males and 5 females aged from 20 to 57 years old with an average of(37.30±10.56) years old. Length of incisions, operation time, blood loss, hospital stays, fracture healing observed by X-ray, position of internal fixation, and changes of coracoclavicular distance were compared, Constant-Murley score was used to evaluate shoulder joint function. RESULTS: All patients were followed up from 22 to 42 months with an average of (30.08±6.72) months. There was no statistical significance in length of incisions, operation time, blood loss, hospital stays and fracture healing time (>0.05). Constant-Murley score in control group was 83.10±5.81, and lower than that of observation group (92.30±6.05)(<0.05) at final following-up. Coracoclavicular distance in control group (11.22±3.85) mm, was longer than that of observation group (8.71±2.14) mm(<0.05). CONCLUSIONS Compared with locking plates, locking plates with suture anchors for type Neer IIb distal clavicle fractures has better shoulder joint, shorter coracoclavicular distance.
