The trend, problems discovered, and enlightenment to hospital management of medical insurance fund unannounced inspection / 中华医院管理杂志

The rational use of medical insurance fund(MIF) plays an important role in promoting the high-quality development of public hospitals, and the supervision of MIF is in a trend of under the rule of law, normalization, professionalization and standardization, and unannounced inspection will become the norm. The authors systematically analyzed three main trends of MIF unannounced inspections, namely, gradually increasing intensity, constantly innovating methods, and increasingly serious consequences. The problems exposed in unannounced inspections were sorted out from five dimensions: form of results, severity, scope of attribution, subjective intention, and regulatory screening ideas. The enlightenment of MIF unannounced inspections to hospital management was explored from four aspects: compliance awareness, organizational system, fine management, and daily supervision. It was proposed that public hospitals should transform their roles and positions, improve the working mechanism of departmental collaboration, and achieve fine management in policy understanding, system formulation, process design, information support, data governance, regulatory implementation, personnel training, and performance matching. At the same time, internal simulated unannounced inspections in hospitals should be regarded as a routine work.

Clinical observation of kidney-tonifying and mind-calming acupuncture therapy in the treatment of perimenopausal insomnia / 针灸推拿医学（英文版）

Objective:To observe the effects of kidney-tonifying and mind-calming acupuncture therapy on sleep,mood,sex hormone levels,and traditional Chinese medicine(TCM)symptoms in patients with perimenopausal insomnia(PMI). Methods:A total of 90 patients with PMI were randomly divided into a treatment group and a control group,with 45 cases in each group.Patients in the treatment group were treated with acupuncture at Shenshu(BL23),Taixi(KI3),Baihui(GV20),and Anmian(Extra).The control group was treated with sham acupuncture.Both groups were treated 3 times a week for 4 weeks.Pittsburgh sleep quality index(PSQI)and insomnia severity index(ISI)were used to evaluate the sleep quality of the subjects before treatment,after treatment,and 1 month after treatment(follow-up).Beck depression inventory(BDI)and Beck anxiety inventory(BAI)were used to evaluate the depression and anxiety of the subjects before treatment,after treatment,and at 1-month follow-up.The TCM symptom scale was used to evaluate the TCM symptoms of the subjects before treatment,after treatment,and 1 month after treatment.Serum levels of estradiol(E2),follicle-stimulating hormone(FSH),and luteinizing hormone(LH)were measured before and after treatment. Results:During the study,2 cases dropped out of the treatment group,and no cases dropped out of the control group.The PSQI scores of the treatment group were significantly lower after treatment and at 1-month follow-up compared with those before treatment(P<0.05),and the difference was statistically significant compared with that of the control group(P<0.05).In the control group,the PSQI score was significantly lower after treatment compared with before treatment(P<0.05),and the difference was not statistically significant at 1-month follow-up compared with before treatment(P>0.05).Compared with the pre-treatment,the ISI,BDI,BAI,and TCM symptom scale scores of the treatment group were lower after treatment and at 1-month follow-up(P<0.05),and the differences with the control group at the same time point were statistically significant(P<0.05).The differences in ISI,BDI,BAI,and TCM symptom scale scores of the control group before treatment,after treatment,and at 1-month follow-up were not statistically significant(P>0.05).After treatment,the serum E2 level in the treatment group was significantly higher than that before treatment(P<0.05),and the difference with the control group was statistically significant(P<0.05).The difference in the serum E2 level before and after treatment in the control group was not statistically significant(P>0.05).The differences in the serum FSH and LH levels between before and after treatment were not statistically significant in either group of subjects(P>0.05). Conclusion:Kidney-tonifying and mind-calming acupuncture therapy can improve sleep quality,relieve anxiety and depression,delay the decrease of serum E2 level,and improve related TCM symptoms in patients with PMI.

Study on the relationship between indexes of different abnormal weight and dyslipidemia in adults in Beijing City / 中华预防医学杂志

Objective: To analyze the relationship and consistency between indexes of different abnormal weight and dyslipidemia in adults in Beijing City. Methods: From August to December of 2017, 4 975 residents aged 18 to 79 years old in 5 districts of Beijing were randomly selected as subjects by using a multi-stage stratified cluster sampling method. Questionnaire, physical examination and laboratory tests were conducted. The prevalence of overweight/obesity, high body fat rate, central obesity, and high waist-to-height ratio was calculated. Partial correlation was used to analyze the correlation of blood lipid with body mass index (BMI), body fat rate, waist circumference and waist-height ratio. Logistic regression analysis for complex sampling was used to analyze the relationship between indexes of different abnormal weight and dyslipidemia after controlling for relevant risk factors, including age, sex, smoking status, drinking, insufficiency intake of vegetable and fruit, physical inactivity. Kappa value was computed to analyze the consistency between indexes of different abnormal weight. Results: The weighted prevalence of dyslipidemia was 30.48%, and it was higher in men than that in women (40.16% vs. 20.52%, P<0.01). The weighted rate of overweight/obesity, high body fat rate, central obesity, and high waist-to-height ratio was 56.65%, 47.52%, 42.48% and 59.45%, respectively. BMI, body fat rate, waist circumference and waist-to-height ratio were positively correlated with the level of total cholesterol, triglyceride, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol, and negatively correlated with high-density lipoprotein cholesterol. Logistic regression analysis for complex sampling showed that the high body fat rate (OR=1.67, 95%CI: 1.35-2.07), overweight/obesity (OR=1.65, 95%CI: 1.26-2.14) and high waist-to-height ratio (OR=1.46, 95%CI: 1.09-1.96) were associated with dyslipidemias. Kappa values of high body fat rate with overweight/obesity, high waist-to-height ratio and central obesity were 0.65, 0.53 and 0.58, respectively (P<0.05). Conclusion: In 2017, the prevalence of dyslipidemia in adults in Beijing City is high, especially in men. Overweight/obesity, high body fat rate and high waist-to-height ratio are associated with dyslipidemia. The high body fat rate is most associated with dyslipidemia.

Analysis of the short-term efficacy of ustekinumab as the first-line treatment for Crohn′s disease / 中华消化杂志

Objective:To evaluate the short-term efficacy of ustekinumab (UST) as the first-line treatment of Crohn′s disease (CD).Methods:From October 1, 2020 to March 1, 2023, at the First Affiliated Hospital of Soochow University, 64 CD patients treated with UST as first-line biologics were enrolled. The patients were classified using the Montreal classification. Clinical and endoscopic response and remission were assessed by Crohn′s disease activity index (CDAI) and simple endoscopic score for crohn′s disease (SES-CD), respectively. Clinical response was defined as a reduction in CDAI score ≥70, and clinical remission was defined as a CDAI score <150; Endoscopic response was defined as ≥50% reduction from baseline in SES-CD score, and endoscopic remission was defined as SES-CD score ≤2. The clinical response rate and clinical remission rate at week 24 and week 48, as well as the endoscopic response rate and endoscopic remission rate at week 48 were observed in CD patients (only 21 patients with endoscopic prognostic results). Mann-Whitney rank sum test was used for statistical analysis.Results:Among 64 CD patients, there were 47 males and 17 females, with an age of (33.5±13.7) years old. According to Montreal classification, there were 3 cases (4.7%) of type A1 (≤16 years old), 44 cases (68.8%) of type A2 (17 to 40 years old), and 17 cases (26.6%) of type A3 (>40 years old); 43 cases (67.2%) of type L1 (terminal ileum type), 10 cases (15.6%) of type L2 (colonic type), 8 cases (12.5%) of type L3 (ileocolonic type), 1 case (1.6%) of type L4 (upper gastrointestinal type), 2 cases (3.1%) of type L1+ L4; 23 cases (35.9%) of type B1 (non-stricturing, non-penetrating), 34 cases (53.1%) of type B2 (stricturing), 2 cases (3.1%) of type B3 (penetrating), 5 cases (7.8%) of type B2+ B3; 44 cases (68.8%) complicated with perianal lesions. Among 56 CD patients with UST maintenance therapy once every 8 weeks, the CDAI scores at week 24 and 48 after treatment were both lower than that at week 0 (64.46(30.61, 123.30), 34.24(15.77, 64.83) vs. 353.40(290.40, 391.30)), and the CDAI score at week 48 after treatment was lower than that at week 24 after treatment, and the differences were statistically significant ( Z=-9.01, -9.13, and -3.14; P<0.001, <0.001, and =0.002). The clinical response rate was 100.0% (56/56) and the clinical remission rate was 91.1% (51/56) at week 24; the clinical response rate was 100.0% (56/56) and the clinical remission rate was 98.2% (55/56) at week 48. Among 39 CD patients complicated with perianal lesions, the closure rate of anal lesions at week 24 was 87.2% (34/39) and at week 48 was 100.0% (39/39). Among 8 CD patients who received UST maintenance therapy once every 12 weeks, the CDAI scores at week 24 and 48 were both lower than that at week 0 (100.40(71.20, 171.30), 38.49(18.25, 143.50) vs. 268.00(242.60, 364.90)), and the differences were statistically significant ( Z=-3.26 and -3.36; both P<0.001). At week 24, 7 CD patients achieved clinical response and 5 CD patients achieved clinical remission. At week 48, 8 CD patients achieved clinical response and 6 CD patients achieved clinical remission. Among 5 CD patients complicated with perianal lesions, 3 CD patients achieved perianal closure at week 24 and all 5 CD patients achieved closure of perianal lesions at week 48. Among 21 CD patients who underwent endoscopic evaluation, 16 CD patients received UST maintenance therapy once every 8 weeks, the SES-CD score at week 48 was lower than that at week 0 (4.00(3.00, 7.75) vs. 9.50(7.25, 10.75)), and the difference was statistically significant ( Z=-3.43, P<0.001), among them, 9 CD patients achieved endoscopic response and 2 CD patients achieved endoscopic remission; 5 CD patients received UST maintenance therapy once every 12 weeks, there was no statistically significant difference in the SES-CD score at week 48 compared with that at week 0 (4.00(1.50, 6.50) vs. 7.00(3.50, 10.00)) ( P>0.05), among them, 3 CD patients achieved endoscopic response and 1 CD patients achieved endoscopic remission. Conclusion:UST as the first-line treatment for CD patients can achieve clinical efficacy (response or remission), and the maintenance therapy is beneficial for endoscopic remission and closure of perianal lesions.

Comparison of the effects of different chromatic lights on accommodative response and microfluctuation in myopes and emmetropes / 中华实验眼科杂志

Objective:To explore the effects of conflicting stimuli generated by different chromatic lights on visual display terminal (VDT) on accommodative response and microfluctuation of myopes and emmetropes, and to investigate the possible relationship between chromatic light, accommodation and the development and progression of myopia.Methods:A non-randomized controlled trial was conducted.Forty-one subjects aged 22 to 30 years old were enrolled, including 19 emmetropes in emmetropic group and 22 myopes in myopic group.The subjects had the normal color vision and no ocular organic diseases.The interventions were screens of different colors.There were 7 chromatic light conditions, including 3 monochromatic lights (red, green, blue), 3 bichromatic lights (red+ green, red+ blue, green+ blue) and 1 polychromatic light (white=red+ green+ blue). Subjects were asked to look at a black E target on a VDT at a distance of 33 cm for more than 20 seconds.The background color of the VDT was changed randomly in the 7 chromatic light conditions.The accommodative responses were recorded with the Grand Seiko WAM-5500 automatic infrared refractor every 0.2 seconds and the accommodative microfluctuation was calculated as the standard deviation of the accommodative response.Accommodative response and accommodative microfluctuation under different chromatic light conditions were compared.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of the First Affiliated Hospital, Zhejiang University School of Medicine (No.2019-1564). Written informed consent was obtained from each subject.Results:No statistically significant difference was found in the accommodative response between the two groups ( Fgroup=2.626, P=0.113). There was a statistically significant difference under different chromatic light conditions between the two groups ( Flight=39.070, P<0.01). There were similar trends in the effects of various color lights in both groups, with the largest accommodative response under monochromatic red light, followed by the bichromatic light containing red light, and then the smallest accommodative response under monochromatic blue light, and the differences were statistically significant (all at P<0.05). The accommodative microfluctuations under red, green, blue, red+ blue, red+ green, blue+ green and white light conditions were (0.142±0.033), (0.128±0.038), (0.131±0.043), (0.139±0.039), (0.127±0.034), (0.131±0.043) and (0.139±0.042)D in emmetropic group, and (0.178±0.043), (0.164±0.043), (0.159±0.039), (0.174±0.042), (0.166±0.036), (0.159±0.031) and (0.174±0.035)D in myopic group, respectively, showing statistically significant differences between them ( Fgroup=12.146, P<0.01; Flight=2.782, P<0.05). The accommodative microfluctuations under the 7 light conditions were higher in myopic group than in emmetropic group, and the differences were statistically significant (all at P<0.05). In myopes, the accommodative microfluctuation was the largest under red light, which was significantly larger than that under blue light, and was the smallest under blue+ green light (all at P<0.05). There was no significant difference in the accommodative microfluctuation between bichromatic light and its two monochromatic lights, or between the polychromatic light (white light) and its three monochromatic lights (all at P>0.05). There was no significant effect of various chromatic lights on the accommodative microfluctuation in emmetropic group (all at P>0.05). Conclusions:The accommodative microfluctuation is greater in myopes than in emmetropes.The stimuli produced by long-wavelength light cause larger accommodative microfluctuation, while conflicting stimuli generated by different chromatic lights do not increase accommodative microfluctuation.

Research progress of retinal microscopic changes after extraocular muscle surgery / 国际眼科杂志(Guoji Yanke Zazhi)

As a primary treatment for strabismus, extraocular muscle surgery can achieve the purpose of correcting the eye position, improving the appearance and reconstructing the third-level visual function. Previous studies have found that the vascular density(VD)and thickness of retina increased in the early stage after extraocular muscle surgery, where multiple mechanisms involved. In recent years, with the appearance of detection means such as optical coherence tomography angiography(OCTA), our quantitative understanding of retinal microscopic changes and their mechanisms brought about by traditional extraocular muscle surgery has become more and more profound. The increase of retinal VD in the early postoperative period may be closely related to the recovery of postoperative visual function. However, the related studies are few, and the association between microscopic changes and visual function after extraocular muscle surgery and its mechanism need to be further clarified. This article will review the microscopic changes of retina and their mechanisms after extraocular muscle surgery from multiple perspectives to improve our understanding of the relationship between the mechanism of its influence and visual function, with a view to provide references for the choice of extraocular muscle surgery scheme and related clinical research.

Tanshinone IIa attenuates vascular calcification through inhibition of NF-κB and β-catenin signaling pathways / 生理学报

Tanshinone IIa is a key ingredient extracted from the traditional Chinese medicine Salvia miltiorrhiza (Danshen), and is widely used to treat various cardiovascular diseases. Vascular calcification is a common pathological change of cardiovascular tissues in patients with chronic kidney disease, diabetes, hypertension and atherosclerosis. However, whether Tanshinone IIa inhibits vascular calcification and the underlying mechanisms remain largely unknown. This study aims to investigate whether Tanshinone IIa can inhibit vascular calcification using high phosphate-induced vascular smooth muscle cell and aortic ring calcification model, and high dose vitamin D3 (vD3)-induced mouse models of vascular calcification. Alizarin red staining and calcium quantitative assay showed that Tanshinone IIa significantly inhibited high phosphate-induced vascular smooth muscle cell and aortic ring calcification. qPCR and Western blot showed that Tanshinone IIa attenuated the osteogenic transition of vascular smooth muscle cells. In addition, Tanshinone IIa also significantly inhibited high dose vD3-induced mouse aortic calcification and aortic osteogenic transition. Mechanistically, Tanshinone IIa inhibited the activation of NF-κB and β-catenin signaling in normal vascular smooth muscle cells. Similar to Tanshinone IIa, inhibition of NF-κB and β-catenin signaling using the chemical inhibitors SC75741 and LF3 attenuated high phosphate-induced vascular smooth muscle cell calcification. These results suggest that Tanshinone IIa attenuates vascular calcification at least in part through inhibition of NF-κB and β-catenin signaling, and Tanshinone IIa may be a potential drug for the treatment of vascular calcification.

Investigation on knowledge, attitude and behavior of salt reduction in adults of Beijing in 2017 / 中华预防医学杂志

Objective: To explore the knowledge, attitude and behavior of salt reduction in adults of Beijing in 2017. Methods: Based on the monitoring data of chronic diseases and corresponding risk factors in adults of Beijing in 2017, the indicators of salt reduction knowledge, attitude and behavior of 13 240 participants aged 18-79 years old were analyzed. The awareness rate, attitude support rate and behavior rate were calculated by complex weighting method, and compared among different age groups, genders, residential areas, and history of hypertension. The proportion of people taking various salt reduction measures to the total number of people was compared. Results: The awareness rate of recommended daily salt intake, the awareness of hypertension caused or aggravated by more salt intake, the attitude support rate and behavior rate of adults were 31.77%, 88.56%, 90.27% and 53.86%, respectively. After weighted adjustment, the awareness rate of recommended daily salt intake was 31.08%, which increased with age (χ2trend=431.56, P<0.001) and education level (χ2trend=95.44, P<0.001). The awareness rate of women was higher than that of men (χ²=118.89, P<0.001), and the awareness rate of population in urban areas was higher than that of population in suburban areas (χ²=34.09, P=0.001). The awareness rate of hypertension caused or aggravated by eating more salt was 86.73%. The support rate of salt reduction attitude was 90.45%. The rate of salt-reducing behavior was 54.05%. Among different salt reduction measures, reducing salt when cooking was the most common measure (52.41%), while the least common one (35.22%) was using low sodium salt. Logistic regression model analysis showed that the gender, age, education level, self-reported history of hypertension, awareness of salt recommendation, awareness of hypertension caused or aggravated by eating more salt, and salt reduction attitude were significantly associated with salt reduction behavior. Conclusion: In 2017, adults in Beijing have a basic understanding of the impact of high-salt diet on health and support salt reduction, but the rate of salt reduction behavior is still relatively low. There are obvious gender and age differences, and the salt reduction measure is simple. Targeted measures should be taken to promote the formation of salt reduction behavior.

Analysis of the current status and related factors of oral nutritional supplements intake among 18-79 years old in Beijing in 2017 / 中华流行病学杂志

Objective: To understand the current status of taking nutrient supplements for residents aged 18 to 79 years old in Beijing and its related factors. Methods: Data were gathered from the 2017 Beijing Non-communicable and Chronic Disease Surveillance Program. Multiple classified cluster sampling method was used, and participants aged 18-79 were sampled from 16 districts. The questionnaire included chronic diseases and related risk factors, health knowledge, and oral nutritional supplements within 12 months. Multivariate logistic regression models were established to analyze associated factors that affect the intake of nutrient supplements. Results: The weighted prevalence of supplements use was 13.1% among 12 696 subjects within the past 12 months. The proportions of multivitamins (4.7%), B vitamins (4.5%), and folic acid (3.2%) were higher. The prevalence of supplement use of young people (18-39 years old) and the elderly (60-79 years old) was higher than middle-aged people (40-59 years old) (χ2=54.09, P<0.001). Except for the age group of 70-79 years old, the consumption rate of women was significantly higher than that of men (P<0.05). After adjusting age and sex, among patients with hypertension, diabetes, or dyslipidemia, the control rates of blood pressure, glucose and lipids of patients who take nutrient supplements were higher than those who do not (P<0.05). And participants who took nutrient supplements had a more heightened awareness rate of health knowledge, such as the hazards of smoking and second-hand smoke, and recommended amount of salt per day (P<0.001). The multi-factor logistic analysis found that nutrient supplement-related factors include women, old age, higher education level, living in urban, insufficient physical activity, sleeping problems, active physical examination, blood pressure control among patients, and health knowledge (P<0.05). Conclusions: The factors of nutrient supplements use were related to sex, age, education level, health status, and health literacy. We should pay attention to key populations and guide them to establish the correct concept of taking nutrient supplements.

Objective: To understand the regular exercise status and influencing factors in 18-64 year-old labor force population in Beijing, and provide evidences for behavioral intervention. Methods: Data were collected from Beijing Adult Non-communicable and Chronic Diseases and Risk Factors Surveillance Program from August to December, 2017. The stratified cluster sampling method was used to select 13 240 survey subjects throughout the city. The valid sample size included in this study were 11 604 persons aged 18 to 64 years. Questionnaire was used to collection the information about basic demographic characteristics, chronic disease history and physical activity prevalence of the study subjects. The body height and weight were measured by standard methods. Fasting venous blood samples were collected for the detection of fasting blood glucose, blood lipids and other biochemical indicators. Software SPSS 20.0 was used fort complex sampling sample weighting and data analysis. Results: The proportions of the study subjects who did regular exercise and never had leisure-time activity in 18-64 year-old labor force population in Beijing were 23.74% (95%CI: 21.51%-26.12%) and 64.34% (95%CI: 61.66%-66.94%) respectively; The average daily physical activity time was 23.44 min (95%CI: 21.16-25.71), and the total daily sedentary behavior time was 6.96 hours (95%CI: 6.80-7.13). With the increase of age, the proportions of the study subjects who did regular exercise and never had leisure-time activity increased (P=0.006, P<0.001). With the increase of educational level, the proportion of those who did regular exercise increased (P<0.001), and the proportion of those who never had leisure-time activity decreased (P<0.001); the higher the level of physical activity, the higher the regular exercise proportion (P<0.001); the proportions of employed people who did regular exercise was lower than those in unemployed people (P<0.001); the proportions of women never had leisure-time activity was higher than those in men (P=0.024). The results of multivariate analysis showed that older age and higher education level were positive factors for regular exercise (35- years old: OR=0.653, 95%CI: 0.530-0.804, P<0.001; 50-64 years old: OR=0.695, 95%CI: 0.560-0.864, P=0.001; high school/technical secondary school/technical School: OR=0.679, 95%CI: 0.593-0.777, P<0.001; college graduation: OR=0.478, 95%CI: 0.387-0.590, P<0.001; bachelor degree and above: OR=0.435, 95%CI: 0.347-0.546, P<0.001), while employment (OR=1.631, 95%CI: 1.330-2.000, P<0.001) and married/cohabitation (OR=1.340, 95%CI: 1.093-1.644, P=0.038) were negative factors for regular exercise. Conclusions: The rate of regular exercise in 18-64 year-old labor force population in Beijing needs to be improved. Older age and high educational level were positive factors for regular exercise, while being married and employed were negative factors for it.

cGAS guards against chromosome end-to-end fusions during mitosis and facilitates replicative senescence

As a sensor of cytosolic DNA, the role of cyclic GMP-AMP synthase (cGAS) in innate immune response is well established, yet how its functions in different biological conditions remain to be elucidated. Here, we identify cGAS as an essential regulator in inhibiting mitotic DNA double-strand break (DSB) repair and protecting short telomeres from end-to-end fusion independent of the canonical cGAS-STING pathway. cGAS associates with telomeric/subtelomeric DNA during mitosis when TRF1/TRF2/POT1 are deficient on telomeres. Depletion of cGAS leads to mitotic chromosome end-to-end fusions predominantly occurring between short telomeres. Mechanistically, cGAS interacts with CDK1 and positions them to chromosome ends. Thus, CDK1 inhibits mitotic non-homologous end joining (NHEJ) by blocking the recruitment of RNF8. cGAS-deficient human primary cells are defective in entering replicative senescence and display chromosome end-to-end fusions, genome instability and prolonged growth arrest. Altogether, cGAS safeguards genome stability by controlling mitotic DSB repair to inhibit mitotic chromosome end-to-end fusions, thus facilitating replicative senescence.

Objective: To observe the effects of acupoint sticking therapy of different dosages and durations on the subjective and objective sleep indicators in insomnia patients.Methods: Ninety-six patients with insomnia due to liver-Qi stagnation and spleen deficiency were divided into a high-dosage 7 d group (25 cases), a high-dosage 14 d group (22 cases), a low-dosage 7 d group (21 cases), and a low-dosage 14 d group (28 cases) using the random numbers generated in a stratified and stage-by-stage manner in combination with the visiting sequence. The four groups all received the same acupuncture treatment, but acupoint sticking therapy varied in dosage and duration. Before and after treatment, the actigraphic readings (total time in bed, total sleep time, sleep efficiency, number of wake bouts, length of wakes after asleep, and sleep latency), Pittsburgh sleep quality index (PSQI) score, and symptoms score of traditional Chinese medicine (TCM) were observed. A correlation analysis was conducted among the subjective and objective indicators. Results: The PSQI score was positively correlated with the total time in bed and total sleep time (P<0.05). After treatment, the sleep latency, PSQI scores, and TCM symptoms scores changed significantly in the four groups (P<0.05). The total sleep time and sleep efficiency gained improvements after treatment in the high-dosage 14 d and low-dosage 14 d groups (P<0.05). The high-dosage acupoint sticking groups had longer total sleep time compared with the low-dosage groups of the same treatment duration (P<0.05). After treatment, the length of wakes after asleep, PSQI scores, and TCM symptoms scores were better in the 14 d groups than in the 7 d groups of the same acupoint sticking dosage (P<0.05). Conclusion: Given the same acupuncture treatment, acupoint sticking therapy of different treatment durations produces different effects on the length of wakes after asleep, PSQI score, and TCM symptoms score in insomnia patients, and the 14-day acupoint sticking treatment is superior to the 7-day treatment.

miR-338-3p Targets and Regulates RNF121 to Promote the Proliferation and Invasion of Human Lung Cancer A549 Cells / 中国生物化学与分子生物学报

Recent studies have shown that miR-338-3p plays an important role in the proliferation and invasion of lung cancer, but whether miR-338-3p regulates lung cancer proliferation and invasion through targeting ring finger protein 121 (RNF121) is still unclear. In order to explore its mechanism, the normal lung cell line MRC-5 and the non-small cell lung cancer line A549 were cultured in vitro. Using qRTPCR and Western blotting detection, we found that the expression of miR-338-3p in A549 lung cancer cells was lower than that in MRC-5 cells, while RNF121 expression increased (P0. 05). In summary, miR-338-3p can target the expression of RNF121 to inhibit the proliferation and invasion of A549 cells and inhibit the growth of subcutaneous transplanted tumors in nude mice. RNF121 is expected to become a new target for the treatment of non-small cell lung cancer.

Modern literature study of auricular point therapy for primary insomnia / 针灸推拿医学（英文版）

Objective: By sorting and analyzing pertinent modern studies targeting auricular point therapy treating primary insomnia (PI), to summarize the point selection rules and clinical efficacy of using auricular points alone or combining it with other therapies in treating PI. Methods: A search on China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), PubMed, Springer and Ovid were conducted from January 1, 1998 till January 31, 2020. Point selection, diagnostic criteria and Pittsburgh sleep quality index (PSQI) in the eligible studies were analyzed and summarized. Results: The difference in PSQI before and after using auricular point therapy alone was more significant than that of using Chinese medication alone (P<0.05), but less significant than that of combining auricular point therapy and acupuncture-moxibustion and Chinese therapeutic massage (tuina) (P<0.05). In the included studies, Shenmen (TF4) was the most commonly used (370 times), followed by Heart (CO15), which was 344 times, and Subcortex (AT4), which was 325 times. In terms of auricular points distribution, points in the auricular concha were the most commonly used (1500 times), followed by those in the antitragus (474 times) and triangular fossa (387 times). Correlation analysis showed that Shenmen (TF4) and Liver (CO12), Sympathetic (AH6a) and Heart (CO15) were used together more often, followed by Shenmen (TF4), Liver (CO12), Spleen (CO13), Kidney (CO10) and Subcortex (AT4), and then Shenmen (TF4), Liver (CO12), Sympathetic (AH6a), Subcortex (AT4) and Heart (CO15). Cluster analysis showed that the auricular points used for PI can be divided into 6 clusters in 2 major groups. One group was Heart (CO15), Subcortex (AT4), Shenmen (TF4), Sympathetic (AH6a), Spleen (CO13), Kidney (CO10), Liver (CO12) and Endocrine (CO18); the other was Occiput (AT3), Stomach (CO4), Pancrease-gallbladder (CO11), Chuiqian (LO4), Small Intestine (CO6), Central Rim (AT2,3,4i) and Sanjiao (CO17). In terms of patterns in traditional Chinese medicine, the pattern of dual deficiency of heart and spleen accounted for the largest proportion in the studies of using auricular points alone or combining it with other treatments to treatment PI, and then it was the pattern of liver depression transforming into fire. Conclusion: In treatment of PI with auricular points alone or combo therapy involving auricular points, Shenmen (TF4) was commonly used, and the commonly used point group consisted of Shenmen (TF4), Liver (CO12), Sympathetic (AH6a) and Heart (CO15). Auricular point therapy can be taken as a complementary therapy in treating PI.

Study on the regulatory effect of herbal cake- partitioned moxibustion on colonic CD206, AMPK and TSC2 in rats with Crohn disease / 针灸推拿医学（英文版）

Objective: To explore the mechanism of herbal cake-partitioned moxibustion in Crohn disease (CD) treatment by observing the effect of herbal cake-partitioned moxibustion on protein expressions of colonic M2 macrophage marker CD206, AMP-activated protein kinase (AMPK) and tuberous sclerosis complex (TSC) 2. Methods: Twenty-six specific pathogen free male rats were randomly divided into a normal group, a model group and a herbal cake-partitioned moxibustion group. The CD model was prepared by enema with the mixture of 5％ (W/V) 2,4,6- trinitrobenzene sulfonic acid (TNBS) and 50％ ethanol at 2:1 (volume ratio). After the model was successfully prepared, rats in the herbal cake-partitioned moxibustion group received herbal cake-partitioned moxibustion at Qihai (CV 6) and bilateral Tianshu (ST 25). Hematoxylin-eosin (HE) staining was used to observe the histopathological changes of rat colon; immunohistochemical technique was used to detect the expression of colonic CD206 protein; Western blot, immunofluorescence, and real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) technologies were used to detect the protein and mRNA expressions of colonic AMPK and TSC2. Results: Compared with the normal group, rats in the model group showed damaged colonic mucosa, missing of the epithelial layer, thickened submucosa, vascular proliferation, massive infiltration of monocytes and lymphocytes, and cracked ulcers that reached the muscle layer. Rats in the herbal cake-partitioned moxibustion group showed reduced intestinal inflammation and healing intestinal epithelium ulcers. Compared with the normal group, rat colonic CD206 protein expression, and the protein and mRNA expressions of colonic AMPK and TSC2 were decreased in the model group (all P<0.01); compared with the model group, rat colonic CD206 protein expression was increased (P<0.01), as well as the protein and mRNA expressions of AMPK and TSC2 in the herbal cake-partitioned moxibustion (all P<0.05). Conclusion: Herbal cake-partitioned moxibustion can reduce intestinal inflammation in CD rats, increase colonic CD206 protein expression, and up-regulate the protein and mRNA expressions of colonic AMPK and TSC2.

Admission delay is associated with worse surgical outcomes for elderly hip fracture patients: A retrospective observational study / 世界急诊医学杂志（英文）

BACKGROUND@#The influence of surgical delay on mortality and morbidity has been studied extensively among elderly hip fracture patients. However, most studies only focus on the timing of surgery when patients have already been hospitalized, without considering pre-admission waiting time. Therefore, the present study aims to explore the influence of admission delay on surgical outcomes.@*METHODS@#In this retrospective study, we recorded admission timing and interval from admission to surgery for included patient. Other covariates were also collected to control confounding. The primary outcome was 1-year mortality. The secondary outcomes were 1-month mortality, 3-month mortality, ICU admission and postoperative pneumonia. We mainly used multivariate logistic regression to determine the effect of admission timing on postoperative outcomes. An additional survival analysis was also performed to assess the impact of admission delay on survival status in the first year after operation.@*RESULTS@#The proportion of patients hospitalized on day 0, day 1, day 2 after injury was 25.4%, 54.7% and 66.3%, respectively. And 12.6% patients visited hospital one week later after injury. Mean time from admission to surgery was 5.2 days (standard deviation 2.8 days). Hospitalization at one week after injury was a risk factor for 1-year mortality (OR 1.762, 95% CI 1.026–3.379, P=0.041).@*CONCLUSION@#Admission delay of more than one week is significantly associated with higher 1-year mortality. As a supplement to the current guidelines which emphasizes early surgery after admission, we also advocate early admission once patients get injured.

Prevalence of decreased estimated glomerular filtration and risk factors among middle-aged and elderly residents in Beijing / 中华全科医师杂志

Objective:To investigate the prevalence of estimated glomerular filtration (eGFR) and risk factors among middle-aged and elderly residents in Beijing.Methods:In August-December of 2017, 6 549 residents aged 45-79 years old were randomly selected in the study by stratified multi-stage cluster sampling method. The investigation was performed by questionnaire, physical examination and laboratory tests. The contents of questionnaire included the demographic characteristic and prevalence of chronic disease. Blood pressure was tested. Fasting venous blood was collected to test the level of total cholesterol (TC), high density lipoprotein cholesterol (HLDL), low density lipoprotein cholesterol (LDL), triglyceride (TG), fasting blood-glucose (FBG), blood creatinine (Cr) and serum uric acid (UA). The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation was used to estimate GFR(eGFR). The decreased GFR was defined as eGFR less than 60 ml/min per 1.73 m 2. The statistical software SPSS 20.0 was used for analysis. The general linear model, test of independence of rows and columns, logistic regression for complex samples were generalized. The weighted mean and weighted rate were analyzed. Results:The average level of eGFR was (100.51±0.54) ml/min per 1.73 m 2. The rate of decreased GFR was 1.28%, and it showed a higher rate in subjects aged 70-79 years-old, living in urban area, with history of cardiovascular disease, hypertension, diabetes mellitus, hyperuricemia (4.53%, 1.57%, 2.90%, 2.27%, 2.12% and 4.62%; F=30.827, 10.588, 11.466, 34.693, 6.788,51.643, all P<0.05) . Logistic regression analysis of complex sampling showed that 70-79 years old ( OR=4.435, 95 %CI:2.402-8.191), living in urban area ( OR=3.145, 95 %CI: 1.540-6.420), hypertension ( OR=4.663, 95 %CI:2.177-9.988), hyperuricemia ( OR=6.751, 95 %CI:3.363-13.553) were associated with decreased GFR (all P<0.05). Conclusion:The prevalence of the decreased eGFR among middle-aged and elderly residents in Beijing is higher than the average level in the eastern part of China. Hypertension, hyperuricemia, the old age and living in urban are risk factors of decreased GFR.
