Objective To compare the clinical efficacies between warm needling and Ibuprofen sustained release capsules (a nonsteroidal anti-inflammatory drug, NSAID) in treating patients with dysmenorrhea in adenomyosis. MethodSixty-five patients with dysmenorrhea induced by adenomyosis were randomized into a treatment group of 33 cases and a control group of 32 cases. The control group was intervened by oral administration of Ibuprofen sustained release capsules, while the treatment group was intervened by warm needling.The intervention lasted 3 menstrual cycles and a 3-month follow-up was studied. The Visual Analogue Scale (VAS), dysmenorrhea symptoms scores and clinical efficacy were compared between the two groups.ResultThe VAS scores after the intervention and inthe first and second months of the follow-up study were significantly different from the pre-treatment score in the two groups (P<0.01); the VAS score of the 3-month follow-up was significantly different from the score before the intervention in the treatment group (P<0.01). There were significant differences in comparing the VAS score after the intervention and in the follow-up study between the two groups (P<0.01), and the treatment group was superior to the control group. The dysmenorrhea symptoms scoresdeclined significantly after the intervention and in the first and second months of the follow-up study in both groups (P<0.01); the dysmenorrhea symptoms score of the 3-month follow-up study decreased in the treatment group and was significantly different from the pre-treatment score (P<0.01). There were significant differences in comparing the dysmenorrhea symptoms scores in the second and third months of the follow-up study between the two groups (P<0.01). The total effective rate was 93.9% in the treatment group, significantly better than 62.5% in the control group (P<0.01).ConclusionWarm needling is effective in easing pain and improving the symptoms of dysmenorrhea in adenomyosis, and can produce a consistent efficacy after the termination of thetreatment; it's superior to NSAIDs in comparing both short-term and long-term treatment efficacies.

Objective To investigate the applicability of autoregressive integrated moving average (ARIMA) model in predicting healthcare-associated infection(HAI) in children.Methods The ARIMA model was constructed according to the incidence of HAI in a hospital from January 2011 to December 2014.With the use of information criterion,optimal model was determined;HAI data in 2015 was as test samples,the feasibility of the model was evaluated.Results ARIMA (0,1,1) was the optimal prediction model for HAI rate,the Akaike Information Criterion (AIC) and Bayesian Information Criterion(BIC) of the ARIMA (0,1,1) were 66.61 and 70.76,respectively.The Ljung-Box statistics value Q =14.14 was not significantly different (P =0.658),suggesting a white noise sequence of residuals with a good model fitting.The mean absolute percent error(MAPE) between actual and fitting value of HAI was 22.4,the actual values were within the 95％ confidence interval.Conclusion ARIMA model fits the time series data,and can achieve satisfactory effect on predicting the incidence of HAI in hospitalized children.

The contribution of angiogenesis inhibitor TNP-470 to the growth and metastasis of ACHN renal cell carcinoma (RCC) was studied. TNP-470 (40 mg/kg, every two days) was administrated to BABL/c nude mice bearing ACHN RCC. The mice were sacrificed after a treatment duration of 31 days and the weight and volume of subcutaneous tumors as well as foci of lung metastasis were measured. The microvascular density (MVD) of the tumor as well as the PCNA index and apoptotic index of the tumor cells were evaluated immunohistochemically. Result showed that the growth of ACHN RCC was suppressed significantly and none metastasis was observed in TNP-470-treated mice. Compared with the control group, the MVD was decreased markedly (P < 0.01) and the apoptotic index was increased significantly (P < 0.01) in the treated group. The tumor volume was positively correlated to the MVD (r = 0.7144, P < 0.01) and inversely correlated to the apoptotic index (r = -0.8607, P < 0.01), and MVD was conversely correlated to the apoptotic index. It was determined that TNP-470 could effectively inhibit angiogenesis of ACHN RCC, which resulting in ischemia and hypoxia, leading to increased apoptosis, thus obviously suppressing the growth and metastasis of ACHN RCC in nude mice.

Objective:To investigate the clinical features, imaging features and gene mutation of a paitent with alanyl-transfer ribonucleic acid synthetase 2 (AARS2) gene mutation- related leukodystrophy and further improve the understanding of this rare disease.Methods:Clinical data of a patient with leukodystrophy associated with AARS2 gene mutation diagnosed in October 2020 at Xiamen Hospital of Beijing University of Chinese Medicine and Huashan Hospital of Fudan University were collected.Results:The male patient, 25 years old, was admitted with the clinical manifestations, including chronic onset dyskinesia, ataxia, nystagmus and psoriasis. Head magnetic resonance imaging (MRI) showed bilateral white matter lesions and cerebellar atrophy. Spine MRI showed vertebral body incomplete fusion. Gene detection showed heterozygous compound AARS2 gene mutation [c.985C>T chr6:44275041(p.R329C) and c.452T>C chr6:44279256(p.M151T)].Conclusions:AARS2 gene mutation-related leukodystrophy is a rare mitochondrial disease in clinical practice. The patient presented with progressive motor deficits in the lower limbs, ataxia, relatively retained cognitive function. MRI revealed abnormal symmetry of corpus callosum and bilateral paraventricular white matter. Heterozygous compound AARS2 gene mutations [c.985C>T chr6:44275041 (p.R329C) and c.452T>C chr6:44279256 (p.M151T)] are one of the pathogenic factors leading to hereditary leukodystrophy.

OBJECTIVETo observe the effects of acupuncture combined with medication on circadian rhythm of blood pressure in patients with essential hypertension.

METHODSSixty-four patients of essential hypertension were randomly divided into an observation group and a control group, 32 cases in each group. All the patients maintained original treatment (taking antihypertensive medication); the patients in the observation group were treated with acupuncture method of ",", once a day, five times per week, for totally 6 weeks (30 times). The circadian rhythm of blood pressure and related dynamic parameters were observed before and after treatment in the two groups.

RESULTS(1) The differences of daytime average systolic blood pressure (dASBP), daytime average diastolic blood pressure (dADBP), nighttime average systolic blood pressure (nASBP) and circadian rhythm of systolic blood pressure before and after treatment were significant in the observation group (all<0.05); the differences of circadian rhythm of blood pressure and related dynamic parameters before and after treatment were insignificant in the control group (all>0.05). The nASBP and circadian rhythm of systolic blood pressure in the observation group were significantly different from those in the control group (all<0.05). (2) After the treatment, the spoon-shaped rate of circadian rhythm of blood pressure in the observation group was higher than that in the control group (<0.05).

CONCLUSIONThe acupuncture combined with medication could effectively improve the circadian rhythm of blood pressure and related dynamic parameters in patients with essential hypertension.

Objective:To explore the performance of the commonly used whole blood C-reactive protein (CRP) detection systems and give related recommendation on the performance requirements of detection systems.Methods:A total of 7 540 venous blood samples from 26 maternal, child and children′s hospitals were collected to conduct this multi-center study on the analytical performance of 5 commonly used whole blood CRP detection systems from March to April in 2019. The blank check, carryover, repeatability, intermediate precision, linearity, sample stability, influence of hematocrit/triglyceride/bilirubin, comparison with SIEMENS specific protein analyzer and trueness were evaluated. The 5 systems included BC-5390CRP autohematology analyzer, AstepPLUS specific protein analyzer, Ottoman-1000 Automated Specific Protein POCT Workstation, i-CHROMA Immunofluorometer equipment Reader and Orion QuikRead go detecting instrument. The 5 systems were labeled as a, b, c, d and e randomly.Results:Within the 5 systems, all values of blank check were less than 1.00 mg/L, the carryovers were lower than 1.00%. The repeatability of different ranges of CRP concentrations including 3.00-10.00, 10.00-30.00 and>30.00 mg/L were less than 10.00%, 6.00% and 5.00%, respectively, and the intermediate precision was less than 10.00%. The linearity correlation coefficients of the 5 systems were all above 0.975, while the slope was within 0.950-1.050. Whole blood samples were stable within 72 hours both at room temperature (18-25 ℃) and refrigerated temperature (2-8 ℃). The CRP results were rarely influenced by high triglyceride or bilirubin, except for the immmunoturbidimetric test based on microparticles coated with anti-human CRP F(ab) 2 fragments. When triglyceride was less than 15.46 mmol/L, the deviation of CRP was less than 10.00%. When bilirubin was less than 345.47 μmol/L, the deviation of CRP was less than 10.00%. CRP was more susceptible to Hct on the systems without Hct correction. The deviation of CRP between different Hct dilution concentration and 40% dilution concentration can reach as high as 67.48%. The correlation coefficients ( r) of 5 systems were all more than 0.975 in the range of 0-300.00 mg/L compared with Siemens specific protein analyzer. All systems passed the trueness verification using the samples with specified values of 12.89 and 30.60 mg/L. Conclusion:The performance of 5 systems can basically meet the clinical needs, but it is suggested that the whole blood CRP detection system without automatic Hct correction should be modified manually.

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.
