Objective The aim of this study was to evaluate the efficacy and side effects of sacubitril/valsartan in the treatment of patients with chronic kidney disease(CKD)at stage 5 with resistant hypertension,and to explore the cardiovascular benefits and security of medical in the patients.Methods Patients with CKD5 resistant hypertension diagnosed and treated in the First Affiliated Hospital of Guangxi Medical University from September 2020 to March 2022 were selected and divided into the observation group(treated with routine treatment of kidney disease at end-stage and sacubitril/valsartan)and control group(include droutine treatment of renal disease at end-stage and ACEI or ARB drugs)according to treatment strategy.The patients in both two groups were treated with adequate dialysis treatment and conventional drug treatment of renal disease at end-stage.The patients were followed up for at least 3 months,the clinical efficacy of three months after treated with sacubitril/valsartan was observed,and the efficacy indicators and security indicators and adverse cardiovascular events were observed,the occurrence of adverse effects during the period of drug use were compared with the control group.Results A total of 110 patients were included in this study and there were 55 cases in each group.There were no significant differences in gender,age,age of dialysis,etiology,dialysis mode and blood pressure between the two groups(P>0.05).The Systolic blood pressure(SBP),diastolic blood pressure(DBP),b-type urinary natriuretic peptide precursor(Pro-BNP)and cardiac function grade in the observation group after treatment was significantly decreased compared with before treatment.The left ventricular ejection fraction(LVEF)and the ratio of LVEF<50%in the observation group was significantly reduced after treatment(P<0.05).SBP,DBP and Pro-BNP decreased 3 months after treatment compared with the baseline before treatment,and improved significantly in the first month after treatment(P<0.05).The decrease of DBP and BNP before and after treatment was significantly different between the two groups,and the decrease of DBP and BNP was more significant in the observation group(P<0.05).The difference of LVEF and left ventricular end diastolic diameter(LVEDD)between the two groups before and after treatment was statistically significant,and the improvement was more obvious in the observation group(P<0.05).There were no significant differences in the safety indicators of serum potassium,estimated glomerular filtration rate(eGFR)and liver function between two groups before and after treatment(P>0.05).In terms of adverse reactions,only 1 case in the control group developed hyperkalemia within 3 months of follow-up,and no hypotension or other adverse reactions occurred in the two groups.Conclusions The treatment of patients with CKD stage 5 hypertension with sacubitril/valsartan has obvious cardiovascular benefits.Sacubitril/Valsartan has efficacy in lowering blood pressure,improving cardiac function and reducing volume load,with less adverse events and higher safety than control group.

Status and associated factors of pre-exposure prophylaxis use among men who have sex with men in 24 cities in China / 中华流行病学杂志

Objective: To understand the cognition and medication use of pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) in China and its associated factors. Method: From August 25 to September 5, 2021, 2 447 MSM were recruited in 24 cities to complete the online questionnaire through a male social interaction platform, Blued 7.5 software. The survey contents included demographic information of the respondents, PrEP awareness and usage, and risk behaviors. Descriptive analysis and multi-level logistic regression were performed for data analysis. SPSS 24.0 and SAS 9.4 software were used for statistical analysis. Results: Among the 2 447 respondents of MSM, 1 712 (69.96%) had heard of PrEP, 437 (17.86%) ever used PrEP, 274 (11.20%) were on PrEP, and 163 (6.66%) had discontinued PrEP; among the 437 cases (whoever used PrEP), more than 61.88% (388/627) adopted emtricitabine/tenofovir disoproxil fumarate regimen, and most of them adopted on-demand regimen. The average PrEP dosage reported in the past year is 1.12 tabletsper person per week. PrEP purchase was primarily via an online channel, and the most concerned factor was the PrEP effectiveness on HIV prevention. The most common reasons for discontinuing PrEP, reported by 163 cases, were the lack of HIV risk perception, the use of a condom to prevent HIV, and the economic burden of PrEP use. The logistic regression analysis showed that PrEP use among MSM in 24 cities was statistically associated with age, monthly income, ever having unprotected anal sex in the past year, used sexual drugs and sexually transmitted disease (STD) diagnosis in the past year. Compared with MSM aged 18-24, the proportion of MSM was relatively lower among those aged 25-44, who discontinued the PrEP (aOR=0.54,95%CI:0.34-0.87) or never used PrEP (aOR=0.62,95%CI:0.44-0.87). The proportion of unprotected anal sex among MSM currently on PrEP use was higher than those who have stopped PrEP and never used PrEP (all P<0.05). Those MSM group, with monthly income higher than 5 000 Yuan, used sexual drugs and STD diagnosis in the past year were more likely to have a higher rate for PrEP usage (all P<0.05). Conclusions: Currently, pre-exposure prophylaxis in the MSM group is primarily obtained via the online channel and adopted in an on-demand mode. Although the PrEP users have reached a certain proportion, it is still necessary to strengthen health education on the PrEP effects and side effects of MSM and to improve the awareness and use rate, especially for young MSM group, which can be combined with the advantages of the internet targeting its needs and use barriers.

Research progress of the regulation effect of traditional Chinese medicine monomer of flavonoids on the pulmonary fibrosis signaling pathway / 中国药房

Pulmonary fibrosis is a chronic， progressive and irreversible interstitial lung disease. At present， there is no specific drug for the treatment of pulmonary fibrosis， and many TCM monomers have potential therapeutic value for pulmonary fibrosis， among which flavonoids are the main representative. For example， total flavones of Astragalus memeranaceus and scutellarin can reduce inflammatory cell infiltration， lung injury and extracellular matrix （ECM） deposition by interfering with transforming growth factor-β1/drosophila MAD protein signaling pathway. Total flavonoids of Oxytropis falcata Bunge and salidroside can inhibit lung inflammation by mediating JAK/signal transduction and transcriptional activator signaling pathway， and prevent the epithelial interstitial transition （EMT） process. Quercetin and Ginkgo biloba leaf extract can reduce the apoptosis of macrophages by inhibiting the nuclear factor-κB signaling pathway and play an anti-pulmonary fibrosis role. Urushetin and proanthocyanidins can promote the morphological recovery of myofibroblasts and reduce ECM deposition through the phosphatidylinositol 3-kinase/protein kinase B/mammalian target protein of rapamycin signaling pathway. Naringin and luteolin can inhibit scorch death of macrophage and inflammation response， and improve lung function and lung tissue injury through NOD-like receptor heat protein domain related protein 3 signaling pathway. The ethanol extract of Phyllanthus emblica and calycosin can improve the inflammatory injury and fibrosis of lung tissue by activating the signaling pathway of nuclear transcription factor erythro2-related factor 2/antioxidant response element. Isogliquiritin can inhibit the phenotypic transformation of epithelial cells and reverse EMT progression by inhibiting extracellular signal-regulating kinase signaling pathway. In the future， scholars should consider developing appropriate drug carriers to improve their bioavailability and further study drug targets and pathways， to provide evidence for the development of traditional Chinese medicine monomers of flavonoids into clinical practice.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective:To compare the outcomes of arthroscopic all-inside repair using puncture needle combined with suture hook versus meniscus repair device Fast-Fix for the treatment of meniscal tear in popliteal hiatus region.Methods:A retrospective cohort study was performed on the clinical data of 48 patients with meniscal tear in popliteal hiatus region admitted to Second People′s Hospital of Fujian Province from January 2014 to December 2017. There were 32 males and 16 females, aged 16-44 years [(28.0±7.8)years]. A total of 25 patients were treated with arthroscopic all-inside repair using puncture needle combined with suture hook (needle-hook group) and 23 patients were treated with meniscus repair device Fast-Fix (Fast-Fix group). The operation time and intraoperative blood loss were compared between the two groups. The function of knee joint was evaluated by Lysholm score, Tegner score and International Knee Documentation Committee (IKDC) score before operation, at 6 months after operation and at the last follow-up. The meniscal healing rate was evaluated by MRI scan at the last follow-up. During the period of follow-up, the incidence of complications (infection, popliteal tendon injury, foreign body irritation, etc.) was compared between the two groups.Results:All patients were followed up for 24-36 months [(25.8±2.5)months]. No significant differences were observed in operation time and intraoperative blood loss between the two groups (all P>0.05). The preoperative Lysholm score, Tegner score and IKDC score were not significantly different between the two groups (all P>0.05). The Lysholm score, Tegner score and IKDC score in needle-hook group were (96.7±3.8)points, (4.3±1.6)points and (95.5±5.4)points at 6 months after operation, significantly higher than those in Fast-Fix group [(93.3±1.6)points, (3.6±0.8)points, (91.9±0.8)points] (all P<0.05). The Lysholm score, Tegner score and IKDC score in needle-hook group were (99.6±1.3)points, (6.1±0.8)points and (99.4±0.2)points at the last follow-up, significantly higher than those in Fast-Fix group [(94.5±1.6)points, (4.8±0.2)points and (97.4±0.5)points] (all P<0.01). The above three scoring systems scored significantly higher in the two groups at 6 months after operation and at the last follow-up than those before operation (all P<0.01). MRI scan showed that the meniscus healing rate in needle-hook group was 92% (23/25) at the last follow-up, higher than 70% (16/23) in Fast-Fix group ( P<0.05). During the period of follow-up, no complication was observed in needle-hook group, but 6 patients [26% (6/23)] in Fast-Fix group had discomfort in the posterolateral muscle of the knee, which was related to popliteal tendon injury or foreign body irritation ( P<0.01). Conclusion:For meniscal tear in popliteal hiatus region, arthroscopic all-inside repair using puncture needle combined with suture hook is superior to meniscus repair device Fast-Fix in aspects of better knee function, higher meniscus healing rate and lower complication rate.

Effect of Total Alkaloids from Nandina domfestica in Attenuating Arsenic Trioxide and Its LC-MS / 中国实验方剂学杂志

Objective::To study the effect of total alkaloids of Nandina domestica in attenuating arsenic trioxide, and analyze chemical constituents of alkaloids extract of Nandina, in order to provide the theoretical basis for studying the effect of N. domestica in attenuating arsenic trioxide with alkaloids extract of N. domestica as effective fraction. Method::The model of acute liver injury induced by arsenic trioxide was used to compare the effects on heart and liver functions of mice between arsenic trioxide alone and total alkaloids of N. domestica combined with arsenic trioxide. The detoxification of total alkaloids on arsenic trioxide was evaluated based on biochemical parameters and pathological report. Peakview (Version1.2, AB SCIEX) software was used to process the mass spectrometry data of total alkaloids of N. domestica. The structures of determined compounds were identified by molecular weight of compound (molecular formula), secondary fragments, chromatographic peak retention and literature information. Result::Among biochemical indicators, creatine kinase(CK), lactate dehydrogenase(LDH), blood urea nitrogen(BUN), malondialdehyde(MDA), alanine aminotransferase(ALT) and amino transferase of aspartate(AST) of the arsenic trioxide group were increased, while elimination rates of Na+ -K+ -adenosine triphosphate(ATP), superoxide dismutase(SOD), catalase(CAT) and serum creatinine(SCr) were decreased, compared with those of the combination group. CK and LDH of the alkaloids extract group were more obviously increased than those of the N. domestica extract group, but with no remarkable difference. In histomorphometric examination, edema of mouse heart cells was improved, and some kidney and liver damages in rats were alleviated. Totally 25 alkaloids of alkaloid extract were identified. Among them, 18 were known, and 7 were unknown, including 3 structural types, in which apomorphine alkaloids were mostly. Conclusion::Heart, kidney and liver damage degrees of the combination group were significantly alleviated compared with the arsenic trioxide group. The total alkaloids fraction extracted and purified have a significant attenuation in arsenic trioxide toxicity. The detoxification of total alkaloids extract was equal to that of N. domestica extract. Furthermore, apomorphine alkaloids, such as nantenine and domesticine, can be used as index components to establish a quality control method for total alkaloids.

The entropy weight TOPSIS model is objective and quantifiable for comprehensive quality evaluation of A. pilosa ，and can effectively evaluate its quality.

Research progress on antitumor activity of quercetin derivatives / 中国中药杂志

Quercetin is a kind of typical flavonoid, mainly found in various vegetables, fruits and Chinese herbs that are consumed daily, with the functions of anti-oxidation, anti-tumor, prevention and treatment of cardiovascular and cerebrovascular diseases. Quercetin is a natural compound with defined anti-tumor activity. Due to its low bioavailability and poor water solubility, quercetin has limitations in clinical application. The quercetin derivatives with good solubility, high bioavailability, metabolic stability, and low toxicity have been obtained through modification of quercetin structure. In recent years, a large number of quercetin ethers, esters, complexes, C-4 carbonyloxy substituted derivatives, A,B-ring modified compounds and other derivatives have been synthesized and tested for in vitro anticancer activity. The quercetin derivatives with anti-tumor activity synthesized in the last 5 years were reviewed in this paper.

Reasons and possible mechanisms for pursuing treatment-free remission in chronic myeloid leukemia / 白血病·淋巴瘤

Tyrosine kinase inhibitor (TKI) targeting BCR-ABL1 has significantly improved the survival and prognosis of patients with chronic myeloid leukemia (CML). However, long-term treatment with TKI has caused many problems like adverse drug reactions, decreasing the quality of patients' life and increasing financial burden. Therefore, whether CML patients can successfully stop taking TKI after reaching a certain therapeutic standard has become a matter of concern. At present, treatment-free remission (TFR) has already become a new target for CML therapy. Several clinical trials have confirmed the feasibility and safety of TFR in specific patient populations, and TFR is now incorporated into clinical guidelines. This paper reviews the main reasons for CML patients' pursuit of TFR and the possible mechanisms of TFR.

OBJECTIVE@#To explore the clinical effect of acupuncture and the potential effect mechanism in patients with premature ovarian failure.@*METHODS@#A total of 104 patients with premature ovarian failure were randomized into an acupuncture group and a western medication group, 52 cases in each one. In the western medication group, the conjugated estrogens tablets were prescribed for oral administration, 0.625 mg each time, once a day, consecutively for 21 days. On the 16th day of medication with conjugated estrogens tablets, the oral administration of medroxyprogesterone acetate tablets were supplemented, 10 mg each time, once a day, consecutively for 5 days, and then, these two kinds of western medication were discontinued for 1 week. A total of 3 cycles were required in treatment with 28 days as an artificial cycle. In the acupuncture group, acupuncture was applied. Two groups of acupoints were selected. The first group of acupoints were stimulated before ovulation and the acupoints were Guanyuan (CV 4), Guilai (ST 29), Taichong (LR 3), Taixi (KI 3), Xuehai (SP 10), Sanyinjiao (SP 6), Zigong (EX-CA 1), Yinlingquan (SP 9), Zusanli (ST 36), Shuidao (ST 28), Dahe (KI 12) and Tianshu (ST 25). The second group of acupoints were stimulated after ovulation and the acupoints included Ciliao (BL 32), Shiqizhui (EX-B 8), Ganshu (BL 18), Shenshu (BL 23), Geshu (BL 17) and Pishu (BL 20). The therapeutic effect was observed and compared in the patients between the two groups, as well as the expressions of interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) and the levels of serum luteinizing hormone (LH), follicule stimulating hormone (FSH) and estradiol (E) before and after treatment.@*RESULTS@#The total effective rate was 90.4% (47/52) in the acupuncture group, higher than 67.3% (35/62) in the western medication group (<0.05). After treatment, the expressions of IFN-γ and TNF-α in the acupuncture group were obviously lower than the western medication group (<0.05). Except for serum LH after treatment, at the end of treatment and in 30 days and 90 days after treatment, the levels of serum E in the acupuncture group were higher obviously than the western medication group and the levels of serum LH and FSH were lower obviously than the western medication group (all <0.05).@*CONCLUSION@#Acupuncture promotes the regular menstruation, effectively regulates the levels of serum LH, FSH and E and improves the pituitary gland and the ovary endocrine in the patients with premature ovarian failure. Such effect may be related to the the improvements in the expressions of IFN-γ and TNF-α, the inhibition of the apoptosis of ovarian granulosa cells, the recovery of ovarian function and the enhancement of reserve capacity.

Correlation analysis between homocysteine level and acute kidney injury after cardiac valve replacement surgery / 中华肾脏病杂志

Objective To investigate the relationship between preoperative serum homocysteine (Hcy) level and acute kidney injury (AKI) after cardiac valve replacement surgery. Methods The data of the inpatients who accepted cardiac valve replacement surgery, age≥18 years, no renal replacement therapy before surgery, non - renal decompensation and preoperative serum creatinine (Scr)＜178 μmol/L, survival within 48 h after surgery, and with preoperative serum Hcy data in the First Affiliated Hospital of Guangxi Medical University from January 1, 2015 to December 31, 2017 was retrospectively analyzed. AKI was diagnosed in patients whose Scr increased more than 26.5 μmol/L (0.3 mg/dl) within 48 hours or 1.5 times higher than baseline within 7 days after surgery. According to this, patients were divided into AKI group and non-AKI group, and the affecting factors for AKI were compared between the two groups. Multivariate logistic regression was used to analyze the independent influencing factors of AKI. The relationship between serum Hcy level and AKI incidence was analyzed by Spearman correlation analysis. Whether the AKI occurred and serum Hcy levels were used as variables to map the receiver operating characteristic curve (ROC), and was used to assess the value of preoperative serum Hcy level for predicting AKI after cardiac valve replacement surgery. Results A total of 810 subjects were included in the study, including 375 males and 435 females. They were (50±11) years old (19-78 years old). Among them, 329 patients with AKI occurred within 7 days after heart valve replacement, and the incidence rate was 40.6% (male 45.9%, female 36.1%). The serum Hcy level in the AKI group was higher than that in the non-AKI group [(15.74±4.55) μmol/L vs (13.87 ± 3.85) μmol/L, t=6.106, P＜0.01]. Multivariate logistic regression analysis showed age (OR=1.030, 95% CI 1.014-1.045, P＜0.001), extracorporeal circulation time (OR=1.011, 95% CI 1.007-1.016, P＜0.001), Scr (OR=1.014, 95%CI 1.005-1.023, P=0.002), serum Hcy (OR=1.059, 95% CI 1.017-1.103, P=0.006), high level of Hcy (＞13.64 μmol/L) (OR=1.465, 95%CI 1.059-2.027, P=0.021) and moderate to severe hyperhomocystinemia (16≤Hcy≤100 μmol/L) [with normal HHcy (Hcy＜10 μmol/L) as reference, OR=2.180, 95% CI 1.245-3.816, P=0.006] were independent influencing factors of AKI after cardiac valve replacement surgery. Spearman correlation analysis showed that the incidence of postoperative AKI increased with the increase of preoperative serum Hcy level (rs=0.927, P＜0.001). The results of ROC curve showed that the area under the curve of the preoperative serum Hcy level predicting AKI after heart valve replacement was 0.701, and the cutoff value was 13.64 μmol/L, with the sensitivity 61.3%, specificity 70.9%. Conclusions Preoperative serum Hcy level is an influencing factor for AKI after cardiac valve replacement surgery. The higher the level of preoperative serum Hcy, the higher the incidence of AKI after cardiac valve replacement surgery. Patients with preoperative serum Hcy levels＞13.64 μmol/L have an increased risk of AKI after cardiac valve replacement surgery.

Association between coagulation indicators and all-cause mortality in sepsis-related acute kidney injury patients / 中华肾脏病杂志

Objective To explore the association between coagulation indicators and all-cause mortality in sepsis-related acute kidney injury (AKI) patients. Methods Clinical data of patients with sepsis-related AKI admitted to the First Affiliated Hospital of Guangxi Medical University from June 10, 2016 to June 10, 2018 were retrospectively analyzed. The patients were divided into death group and survival group according to the outcome of 28 d. The risk factors of all-cause mortality in sepsis-related AKI patients were analyzed. Receiver operating characteristic curve (ROC) was used to evaluate the prognostic value of independent risk factor for the death of sepsis-related AKI patientsand Kaplan-Meier method was used to draw the survival curve. Results A total of 214 patients with sepsis-related AKI were enrolled into this study. Their age was (57.90±16.96) years old, and the ratio of male to female was 2.57:1. There was at least one abnormal coagulation indicator in 74.77％(160/214) of patients, and multiple organ dysfunction syndrome (MODS) in 37.38％ of patients. The 28-day all-cause mortality was 28.04％(60/214). Prothrombin time, activated partial thrombin time (APTT), international standardized ratio, thrombin time, procalcitonin, abnormal coagulation indicators and the incidence of MODS in the death group were higher than those in the survival group, while body weight, hemoglobin, the percent of neutrophile granulocyte, platelet count, prothrombin activity, serum albumin and the proportion of renal replacement therapy (RRT) were lower than those in the survival group (all P<0.05). Cox regression analysis suggested that sepsis-related AKI patients with prolonged APTT had a higher risk for all-cause death (HR=2.610, 95％CI 1.077-6.326, P=0.034). The Kaplan-Meier survival curve indicated that 28 d survival rate of APTT extension group was lower than that of the non-APTT extension group (37.1％ vs 70.6％, Log-rank χ2=16.881, P<0.001), and the average survival time was shorter than that of the non-APTT extension group (21.79 d vs 24.73 d). Conclusions Coagulation abnormalities are common in patients with sepsis-related AKI, which are also correlated to the all-cause death. APTT extension is an independent risk factor for the all-cause death in sepsis-related AKI patients.

Impacts of Age and Gender on Vision in School Children Accepting Physical Activities / 中国康复理论与实践

Objective:To investigate the impact of age and gender on kinetic visual acuity (KVA) and static visual acuity (SVA) in school children accepting physical activities. Methods:From May, 2018 to September, 2019, 1465 school children from various schools of Suzhou City were measured SVA and KVA with standard logarithmic visual chart and KVA detector. Results:KVA increased with age as six to nine years old, and decreased as eleven to 14. KVA was better in boys than in girls (t = 5.147, P < 0.001). SVA decreased with age as six to eight years old, fluctuated as eight to eleven, and decreased as eleven to 14, especially for girls. SVA was also better in boys than in girls (t = 3.692, P < 0.001). The prevalence of myopia increased with age as six to eight years old, and increased more significantly as eleven to 14. There was a low positive correlation between age and KVA (r = 0.046, P < 0.05), and a moderate negative correlation between age and SVA (r = -0.364, P < 0.05). KVA was positively correlated with SVA (r = 0.409, P < 0.05). Age, gender, KVA, right SVA and left SVA were the factors related with SVA. Conclusion:Vision is better in school boys than in girls. There is positive correlation between age and KVA. It is necessary to develop physical exercise according to age and gender to improve vision development, especially at the sensitive stage of visual function.

Effect of Three Types of Ball Playing on Kinetic Visual Acuity for Children in Junior Grades / 中国康复理论与实践

Objective:To observe the effect of football, badminton and table tennis on kinetic visual acuity for children in grade one to three at elementary schools. Methods:From February to June, 2019, A total of 123 children aged seven to nine years from four elementary schools were divided into control group (n = 32), badminton group (n = 33), table tennis group (n = 30) and football group (n = 28). The children in the experimental groups accepted ball playing training for 16 weeks, while the control group did not attended any training course. The kinetic visual acuity was measured before and after training. Results:The kinetic visual acuity improved after training in the experimental groups (t > 2.196, P < 0.05), but not in the control group (t = 1.570, P > 0.05). The rates of improvement of kinetic visual acuity were: football (26.82%), badminton (25.44%) and table tennis (19.21%). Conclusion:The ball games play a positive role in improving kinetic visual acuity for children in junior grades, especially the big ball games.

Study on dryness effect of Atractylodis Rhizoma based on theory of dry-dry and dryness-induced Yin deficiency / 中国中药杂志

In order to establish a more perfect evaluation system for dryness effect of Atractylodis Rhizoma, determine the main dry parts of Atractylodis Rhizoma，and further define the mechanism of stir-baked Atractylodis Rhizoma in reducing the dryness. The healthy rats were given with different doses of water extract and volatile oil of raw Atractylodis Rhizoma and stir-baked Atractylodis Rhizoma for 21 days. Based on the theory of the dry-dry and dryness-induced Yin deficiency, the amount of drinking water, tissue morphology of submandibular glands, urine volume and the expression of aquaporin 2 (AQP2) in the kidneys, as well as blood rheology, ratio of cAMP/cGMP in serum and the content of Na⁺-K⁺-ATP enzyme were selected as the evaluation indexes. The results indicated that the rats with high dose volatile oil from raw Atractylodis Rhizoma had a significant increase in the amount of drinking water, urine volume, blood viscosity, ratio of cAMP/cGMP and content of Na⁺-K⁺-ATP enzyme in the serum（<0.05）as compared with the soybean oil group; meanwhile, atrophy of submandibular acinar gland was obvious，and the expression of aquaporin 2 was reduced significantly（<0.05）. There were significant differences between volatile oil high dose group of raw Atractylodis Rhizoma and volatile oil high dose group of stir-baked Atractylodis Rhizoma. There was no significant difference between the water extract groups of raw and stir-baked Atractylodis Rhizoma and the saline group. A comprehensive evaluation system for the dryness effect of Atractylodis Rhizoma was established. It was confirmed that the volatile oil part was the main dry part of Atractylodis Rhizoma. It revealed that the mechanism of dryness effect of Atractylodis Rhizoma was not only related to the decrease of the total content of the volatile oil, but also may be related to the transformation of dryness components in the volatile oil. It provides references for the study of material basis of Atractylodis Rhizoma dryness, provides an experimental basis for the clinical application of Atractylodis Rhizoma, further clarifies the mechanism of stir-baked Atractylodis Rhizoma in reducing the dryness, and provides thoughts for the evaluation of other dry traditional Chinese medicines.
