Research on early warning model of the hearing loss of workers exposed to noise / 中华劳动卫生职业病杂志

Objective: To explore the change of hearing threshold of workers exposed to noise, establish an individual-based hearing loss early warning model, accurately and differentiated the health of workers exposed to noise. Methods: In September 2019, all physical examination data of 561 workers exposed to noise from an enterprise were collected since their employment. Three indicators of average hearing threshold of the better ear, namely, at high frequency, 4000 Hz and speech frequency, were constructed. The generalized estimating equation (GEE) was used to adjust gender and age and establish the warning model of each indicator. Finally, sensitive indicators and warning models were screened according to AUC and Yoden index. Results: Among the 561 workers exposed to noise, 26 (4.6%) workers had hearing loss. The sensitivity indicators were the average hearing threshold at speech frequency ≥20 dB, high frequency ≥30 dB and 4000 Hz ≥25 dB. The AUC of each index was 0.602, 0.794 and 0.804, and the Youden indexes were 0.204, 0.588 and 0.608, respectively. In GEE of hearing loss warning models, high-frequency hearing threshold ≥20 dB and 4000 Hz hearing threshold ≥25 dB were the optimal models, with AUC of 0.862. Conclusion: Combined with the changes of individual hearing threshold over the years, can accurately assess the risk of individual hearing loss of workers exposed to noise.

Overview of systematic reviews of Shufeng Jiedu Capsules / 中国中药杂志

At present, there have been many clinical trials and systematic reviews/Meta-analysis proving the good clinical efficacy of Shufeng Jiedu Capsules in the treatment of respiratory diseases, while comprehensive discussion is still required. This article overviews and analyzes the systematic reviews/Meta-analysis of Shufeng Jiedu Capsules to provide evidence support for clinical practice. The systematic reviews/Meta-analysis of Shufeng Jiedu Capsules were searched from CBM, Wanfang, CNKI, VIP, PubMed, EMbase and Cochrane Library. The AMSTAR 2 scale and GRADE system were respectively employed for the evaluation of methodological quality and the grading of evidence quality. Finally, 8 systematic reviews/Meta-analysis published during 2018-2021 were included for analysis. The diseases involved include acute exacerbation of chronic obstructive pulmonary disease, community-acquired pneumonia, acute tonsillitis, acute exacerbation of chronic bronchitis and acute upper respiratory tract infection. The number of included RCTs studies ranged from 8 to 25. The results showed that Shufeng Jiedu Capsules combined with western medicine routine had better therapeutic effect than the latter alone in the treatment of the above five diseases. The reported adverse reactions caused by Shufeng Jiedu Capsules were mainly gastrointestinal discomforts such as mild nausea, diarrhoea and vomiting, with low incidence and mild symptoms, which can be relieved by drug withdrawal. The methodological quality of the included studies was extremely low, and the outcome indicators were mainly of low and very low grades. The efficacy and safety of Shufeng Jiedu Capsules in the clinical treatment of diseases still need to be verified based on more high-quality studies. The relevant clinical research and systematic review/Meta-analysis should pay more attention to methodological quality and reporting standards and strengthen the scientificity of research.

Efficacy observation of long-retaining scalp acupuncture plus interactive training for upper-extremity dysfunction after cerebral stroke / 针灸推拿医学（英文版）

Objective: To observe the efficacy of long-retaining scalp acupuncture plus interactive training in improving upper- extremity dysfunction in cerebral stroke patients. Methods: Ninety-five patients with upper-extremity dysfunction after cerebral stroke were randomized into two groups, with 48 cases in the treatment group and 47 cases in the control group. Conventional internal medicine treatment was offered to both groups. In both groups, Anterior Oblique Line of Vertex-temporal (MS 6, the middle 2/5) and Posterior Oblique Line of Vertex-temporal (MS 7, the middle 2/5) were selected from the same side of the brain lesion (the side apposing to the hemiplegic limb) for scalp acupuncture treatment. In the treatment group, the scalp acupuncture needles were retained for 7 h, in combination with interactive training, while the needles were also retained for 7 h in the control group but without interactive training. Prior to treatment and at 2-week and 4-week treatment, the two groups were scored using the functional test for the hemiplegic upper extremity-Hong Kong (FTHUE-HK) and simplified Fugl-Meyer assessment-upper extremity (FMA-UE). Results: The total effective rate was 97.9％ in the treatment group, higher than 74.5％ in the control group (P<0.01). The FTHUE-HK score was higher at 2-week and 4-week treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FTHUE-HK score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FTHUE-HK score was higher in the treatment group than in the control group, showing significant between-group differences (both P<0.05). During the whole treatment process, the treatment group had higher FTHUE-HK scores compared with the control group, but there was no statistical significance comparing the change of the score between the two groups at 2-week treatment (P>0.05), while the between-group difference in the change of the score was statistically significant at 4-week treatment (P<0.05). The FMA-UE score was higher at 2-week and 4-weeks treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FMA-UE score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FMA-UE was higher in the treatment group than in the control group, and the between-group differences were statistically significant (both P<0.01). The FMA-UE score rose gradually with the increase of treatment session, and there was statistical significance comparing the change of the score between the two groups at 2-week and 4-week treatment, respectively (both P<0.05). Conclusion: Long-retaining scalp acupuncture plus interactive training results in more significant efficacy than long-retaining scalp acupuncture alone in improving the upper-limb dysfunction after cerebral stroke and the advantage becomes more notable after 2-week consecutive treatment.

Association between maternal blood lipid level during pregnancy and risk of small-for-gestational-age infants / 预防医学

@#Small for gestational age ( SGA ),one of the major adverse pregnancy outcomes, significantly increases the risk of perinatal death and metabolic diseases in adulthood. It is of great significance to strengthen early surveillance and intervention for SGA prevention. Dyslipidemia during pregnancy, as a common metabolic disorder, has been considered to correlate with the increased risk of SGA; however, the epidemiological evidence is still controversial. We have systematically reviewed the recent studies related to the association between serum lipid level during pregnancy and the risk of SGA, so as to provide reference for prevention and intervention of SGA.

Systematic evaluation and sequential Meta-analysis of modified Xuefu Zhuyu Decoction combined with Western medicine in treatment of leiomyoma / 中国中药杂志

CNKI, PubMed and other databases were retrieved to extract eligible randomized controlled trial(RCT) about modified Xuefu Zhuyu Decoction(MXZD) combined with Western medicine(trial group) versus Western medicine alone(control group) in the treatment of leiomyoma. Therefore, a total of 25 RCTs were included, involving 2 328 patients. Bias risk evaluation tool in Cochrane Handbook 5.1.0 was used for evaluating the quality of these RCTs. Meta-analysis was performed for the reported indicators, including total efficiency, serum hormone level [progesterone(P), luteinizing hormone(LH), estradiol(E_2), follicle stimulating hormone(FSH)], uterine size, fibroids size and adverse reactions by using Stata 14.0 software. Meta-analysis showed that the total efficiency(RR=1.21,95%CI[1.17,1.25],P<0.05) of trial group was better than that of control group. Serum hormone level(WMD_P=-3.86,95%CI[-4.31,-3.41],P<0.05; WMD_(LH)=-3.64,95%CI[-4.47,-2.82],P<0.05; WMD_(E_2)=-39.99,95%CI[-53.45,-26.52],P<0.05; WMD_(FSH)=-3.79,95%CI[-4.86,-2.72],P<0.05), uterine size(WMD=-50.02,95%CI[-55.98,-44.06],P<0.05), fibroids size(WMD=-15.79,95%CI[-18.11,-13.46],P<0.05) and adverse reactions(RR=0.65,95%CI[0.48,0.88],P<0.05) of trial group were all lower than those of control group, with statistical significances. Trial sequential analysis(TSA) was performed by using TSA 0.9 software, and showed a reliable therapeutic effect of the experimental group. In short, our study indicated that modified Xuefu Zhuyu Decoction combined with Western medicine had a better therapeutic effect on leiomyoma than Western medicine alone, but more high-quality studies are needed to verify this conclusion in the future.

Recent progress of host susceptibility gene polymorphisms in Isoniazid induced liver injury / 中华实用儿科临床杂志

Tuberculosis (TB) is an infectious fatal disease that seriously endangers human health worldwide.Isoniazid (INH) is an important first-line drug for TB, but it can cause serious adverse drug reactions, such as liver injury and even liver failure.At present, it is believed that metabolites of INH, imbalance of oxidative stress responses and immune response disorders are major causes of INH induced liver injury.In addition, involved genes and gene polymorphisms are susceptible to liver injury caused by INH.In this paper, the association of INH induced liver injury with the polymorphisms of genes related to INH metabolizing enzymes, as well as oxidative stress and immune responses are summarized to improve the understanding of INH induced liver injury and provide novel directions for its prevention and treatment.

A pulmonary source of infection in patients with sepsis-associated acute kidney injury leads to a worse outcome and poor recovery of kidney function / 世界急诊医学杂志（英文）

BACKGROUND@#Hospital mortality rates are higher among patients with sepsis-associated acute kidney injury (SA-AKI) than among patients with sepsis. However, the pathogenesis underlying SA-AKI remains unclear. We hypothesized that the source of infection affects development of SA-AKI. We aim to explore the relationship between the anatomical source of infection and outcome in patients with SA-AKI.@*METHODS@#Between January 2013 and January 2018, 113 patients with SA-AKI admitted to our Emergency Center were identified and divided into two groups: those with pulmonary infections and those with other sources of infection. For each patient, we collected data from admission until either discharge or death. We also recorded the clinical outcome after 90 days for the discharged patients.@*RESULTS@#The most common source of infection was the lung (52/113 cases, 46%), followed by gastrointestinal (GI) (25/113 cases, 22.1%) and urinary (22/113, 19.5%) sources. Our analysis showed that patients with SA-AKI had a significantly worse outcome (30/52 cases, P<0.001) and poorer kidney recovery (P=0.015) with pulmonary sources of infection than those infected by another source. Data also showed that patients not infected by a pulmonary source more likely experienced shock (28/61 cases, P=0.037).@*CONCLUSION@#This study demonstrated that the source of infection influenced the outcome of SA-AKI patients in an independent manner. Lung injury may influence renal function in an as yet undetermined manner as the recovery of kidney function was poorer in SA-AKI patients with a pulmonary source of infection.

Value of ginsenoside Rb1 in alleviating coronary artery lesion in a mouse model of Kawasaki disease / 中国当代儿科杂志

OBJECTIVE@#To study the effect and related signaling pathways of ginsenoside Rb1 in the treatment of coronary artery lesion (CAL) in a mouse model of Kawasaki disease (KD).@*METHODS@#BALB/c mice were randomly divided into a control group, a model group, an aspirin group, a low-dose ginsenoside Rb1 group (50 mg/kg), and a high-dose ginsenoside Rb1 group (100 mg/kg), with 12 mice in each group. All mice except those in the control group were given intermittent intraperitoneal injection of 10% bovine serum albumin to establish a mouse model of KD. The mice in the aspirin group, the low-dose ginsenoside Rb1 group, and the high-dose ginsenoside Rb1 group were given the corresponding drug by gavage for 20 days after modeling. Hematoxylin and eosin staining was used to observe the pathological changes of coronary artery tissue. ELISA was used to measure the levels of the inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) in serum and coronary artery tissue. Western blot was used to measure the relative expression levels of proteins involved in the regulation of the AMPK/mTOR autophagy signaling pathway and the PI3K/Akt oxidative stress signaling pathway in coronary artery tissue.@*RESULTS@#The observation of pathological sections showed that compared with the model group, the high-dose ginsenoside Rb1 group had significant improvement in the symptoms of vascular wall thickening, intimal edema, fiber rupture, and inflammatory infiltration of endothelial cells. Compared with the control group, the model and low-dose ginsenoside Rb1 groups had significant increases in the levels of TNF-α, IL-6, and IL-1β in serum and coronary artery tissue (P0.05) and had significant increases in the expression levels of P-AKT/AKT and P-GSK-3β/GSK-3β (P<0.05), while the high-dose ginsenoside Rb1 group had significant increases in the relative protein expression levels of the above three proteins (P<0.05). Compared with the low-dose ginsenoside Rb1 group, the aspirin group and the high-dose ginsenoside Rb1 group had significant reductions in the levels of TNF-α, IL-6, and IL-1β (P<0.05); the high-dose ginsenoside Rb1 group had significant increases in the expression levels of P-PI3K/PI3K and P-AKT/AKT (P<0.05).@*CONCLUSIONS@#Ginsenoside Rb1 can effectively alleviate CAL in a mouse model of KD in a dose-dependent manner, possibly by regulating the AMPK/mTOR/P70S6 autophagy signaling pathway to inhibit CAL inflammation and regulating the PI3K/AKT/GSK-3β oxidative stress signaling pathway to exert a biological activity of protection against coronary artery endothelial cell injury.

Response of Glucocorticoid Receptor Alpha and Histone Deacetylase 2 to Glucocorticoid Treatment Predicts the Prognosis of Sudden Sensorineural Hearing Loss

OBJECTIVES: To investigate glucocorticoid receptor (GR) and histone deacetylase 2 (HDAC2) gene expression and protein levels in peripheral blood mononuclear cells (PBMCs) of patients with severe or profound sudden sensorineural hearing loss (SSNHL) and to explore the roles of GRs and HDAC2 in glucocorticoid (GC) insensitivity. METHODS: Fifty-five severe or profound SSNHL patients were enrolled in the study. According to hearing improvement after GC treatment, patients were assigned into two groups: GC-sensitive and GC-resistant. A normal reference group included 20 healthy volunteers without hearing loss. Quantitative real-time polymerase chain reaction and Western blot analyses were used to detect the relative expression of GRα, GRβ, and HDAC2 in PBMCs at the mRNA and protein levels. RESULTS: The protein levels of GRs and HDAC2 in PBMCs of SSNHL patients were lower than the normal reference values before GC treatment. Compared with the GC-resistant group, both the mRNA and protein levels of GRα and HDAC2 were significantly increased in the GC-sensitive group after GC treatment. CONCLUSION: A lack of GRα and HDAC2 induction following steroid treatment in GC-resistant SSNHL patients may play a fundamental mechanistic role in GC insensitivity. Response of GRα and HDAC2 to steroid treatment may, thus, predict the prognosis of hearing improvement in SSNHL patients.

Methods: A retrospective study was conducted on 405 patients with CB who met the inclusion criteria. All patients were treated with dog-days acupoint application or Magic Acupuncture Patch between 2013 and 2017. The clinical data of 405 patients were statistically analyzed to compare the prevention and treatment effects of dog-days acupoint application and Magic Acupuncture Patch, and different degrees of stimulation of dog-days acupoint application. Results: Among the dog-days acupoint application groups, the total effective rate was 63.6％ in the light stimulation group, 93.1％ in the moderate stimulation group, and 94.8％ in the strong stimulation group. The differences in the total effective rate between the light stimulation group and the moderate stimulation group, as well as the strong stimulation group, were statistically significant (both P<0.05). There was no significant difference in the total effective rate between the moderate stimulation group and the strong stimulation group (P>0.05). The total effective rate was 83.9％ in the dog-days acupoint application group, versus 45.4％ in the Magic Acupuncture Patch group, and there was a statistically significant difference between the two groups (P<0.05). Conclusion: The efficacy of dog-days acupoint application in the prevention and treatment of CB is better than that of Magic Acupuncture Patch; the degree of stimulation is the basis for the effect of dog-days acupoint application on prevention and treatment of CB, and the moderate and strong stimulations are more appropriate.

Prevalence and risk factors of abnormal glucose metabolism in adults with hypertension in Zhengzhou / 中华健康管理学杂志

Objective This study aims to analyze the prevalence, distribution, and risk factors of abnormal glucose metabolism in urban and rural adult hypertension patients in Zhengzhou. Methods The study was conducted on permanent residents aged 18 years and over (with at least 6 months of residence) in urban and rural areas of Zhengzhou. The survey subjects were chosen by the multi‐stage sampling method. Basic information regarding the height, weight, waist circumference, and blood pressure of 6 798 people who met the standards of admission and discharge were obtained through an on‐site questionnaire survey and physical examination. Blood samples were collected and blood glucose and lipid levels were detected. Results There were 1 985 patients with hypertension, with a prevalence rate of 29.20% and the standardized prevalence rate was 26.53%. Blood samples were collected from 1 936 hypertensive patients (55.8±13.6 years), of whom 903 were male (46.64%) and 1 033 female (53.36%). Among 1 050 patients (54.24%) with abnormal glucose metabolism, the impaired fasting glucose rate was 4.44%, the decreased glucose tolerance rate was 22.21%, and the diabetes rate was 27.56%. Blood samples were collected from 4 748 non‐hypertensive patients and 1 123 patients (23.65%) with abnormal glucose metabolism. The prevalence of abnormal glucose metabolism in hypertensive patients was significantly higher than that in non‐hypertensive patients, and the difference was statistically significant (χ2=586.264, P<0.001). The prevalence rate of abnormal glucose metabolism in hypertensive patients was higher in females, 58.57%, than in males, 49.28% (χ2=16.743, P<0.001). Urban patients showed a higher abnormal glucose metabolism, 57.68%, than rural patients did, 51.67% (χ2=6.984, P<0.001), and the prevalence of abnormal glucose metabolism in hypertensive patients showed a significant upward trend with an increase in age. Patients with central obesity, abnormal blood lipids, family diabetes history, non‐smokers, and non‐drinkers showed a higher prevalence of abnormal glucose metabolism, and the differences were statistically significant (P<0.05). The prevalence of abnormal glucose metabolism increased with age and body mass index, and decreased with increase in education level, with differences being statistically significant (P<0.001). Multivariate logistic regression analysis showed that age, obesity, centripetal obesity, dyslipidemia, and family history of diabetes were the main risk factors for abnormal glucose metabolism in patients with hypertension. Conclusions There is a relatively high prevalence of abnormal glucose metabolism in hypertension patients among the urban and rural residents of Zhengzhou. In the management of hypertension, the detection and intervention for reducing abnormal glucose metabolism should be strengthened and related risk factors must be prevented. The age for health management objectives among hypertension and diabetes patients should be further reduced.
