Objective To provide reference for the optimization and improvement of interoperability between the standard system of the Chinese Pharmacopoeia and other standards.Methods The interoperability of various pharmacopoeia standard systems was compared by searching for citations from the Chinese Pharmacopoeia,the United States Pharmacopoeia-National Formulary,the European Pharmacopoeia,the Japanese Pharmacopoeia,and other standards,including references to domestic regulations and guidelines,standards of the International Organization for Standardization,guidelines from the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use,documents of the World Health Organization,and standards from other countries and international organizations.Results In recent years,pharmacopoeias in the world had continuously increased the citation of non pharmacopoeial standards.The types,quantities,and fields of the United States Pharmacopoeia-National Formulary referencing other standards far exceed those of other pharmacopoeias.The Chinese Pharmacopoeia cites the least number of other standards.Conclusion It is suggested that the Chinese Pharmacopoeia should enhance the interoperability with other standard systems in the standards of various professional fields,enhance the openness,harmonization and advantages,and form a more complete standard system.

Objective: To study the association between 24 h activities and Fundamental Motor Skills (FMS) among children with autism spectrum disorder (ASD) using compositional data analysis, and the expected changes in FMS after isochronous substitution of each activity, in order to provide reference basis for improving FMS levels in children with ASD. Methods: From October 2023 to April 2024, a total of 301 children with ASD aged 6-10 from 7 special education schools in Jinan, were investigated by cluster random sampling, and 24 h movement behaviors were calculated based on accelerator data. Test of Gross Motor Development- 2 was used to assess FMS. R software was used to perform the descriptive statistical, multiple linear regression and isochronous substitution analyses. Results: The proportion of moderatevigorous physical activity (MVPA) in children with ASD was positively related with FMS scores, locomotor, and object control skills ( β=12.42, 6.32, 6.10, P <0.01). Reallocating 15 min from sleep (SLP) to MVPA resulted in respective increases of 3.66, 1.91, and 1.75 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Reallocating 15 min from sedentary behavior (SB) to MVPA resulted in respective increases of 3.72, 1.88 , and 1.83 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Reallocating 15 min from light physical activity (LPA) to MVPA resulted in respective increases of 3.32, 1.57, and 1.74 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Moreover, reallocating 15 min from SB to LPA resulted in an increase of 0.28 points in locomotor skills ( P <0.05). Dose response analysis revealed that substitution of MVPA for SLP, SB, and LPA in children with ASD enhanced their FMS levels, and their substitution was asymmetrical; and substitution of LPA for SB enhanced locomotor skills level. Conclusions Among the 24 h movement behaviors, increasing the time spent on MVPA and LPA have positive impacts on the FMS of children with ASD. Schools and families should optimize the allocation of 24 h activity time in children with ASD, so as to promote the improvement of FMS levels of children with ASD.

The standard system refers to the scientific organic whole formed by the internal connections of stand-ards within a certain range.The completeness of the drug standard system plays a crucial role in ensuring drug safety.Pharmacopoeia is the core of the drug standard system.This article compared the architecture of the Chi-nese Pharmacopoeia,the United States Pharmacopoeia,the European Pharmacopoeia,and the Japanese Pharma-copoeia on the aspects of overall architecture,monographs architecture,general notice architecture,general tech-nical requirements architecture,and other standard architecture,as well as the implementation of various types of standards,aiming to provide reference for the optimization and improvement of the standard system of the Chinese Pharmacopoeia.

Objective:To construct a nomogram for predicting unfavorable prognosis at 6 months after moderate and severe traumatic brain injury (msTBI) and validate its predictive effectiveness.Methods:A retrospective cohort study was conducted to analyze the clinical data of 387 patients with msTBI who were admitted to 904th Hospital of the Joint Logistic Support Force of PLA from January 2020 to December 2022, including 265 males and 122 females, aged 6-97 years [58(47, 68)years]. According to the Glasgow outcome scale (GOS) score at 6 months after injury, the patients were divided into favorable prognosis group (GOS 4-5 points, n=201) and unfavorable prognosis group (GOS 1-3 points, n=186). The clinical characteristics, imaging manifestations, and laboratory test results of the two groups on admission were recorded. Univariate analysis was applied to evaluate the correlation between the aforementioned indicators and the unfavorable prognosis of the msTBI patients at 6 months after injury. Receiver operating characteristic (ROC) curves of single variable and the correlation heatmap among continuous variables were plotted. Lasso regression was used to select variables and multivariate Logistic regression analysis was used to determine independent predictive factors so as to construct Logistic regression equation and plot the nomogram. The internal verification was carried out by means of random and non-random split of data. In random split, the data were divided randomly with a ratio of 6∶4 into training group ( n=232) and verification group ( n=155). In non-random split, the patients admitted from January 2020 to December 2021 were assigned to the training group ( n=260), while those admitted from January 2022 to December 2022 to the verification group ( n=127). Area under the curve (AUC) was used to evaluate the predictive ability of the model in the training group and verification group, calibration curve and Hosmer-Lemeshow (H-L) test to evaluate its goodness of fit, and decision curve analysis (DCA) to evaluate its clinical applicability. The influence of inclusion of neutrophil-to-lymphocyte ratio (NLR) model on the warning effectiveness of poor prognosis was analyzed in comparison with the model without inclusion of NLR. Results:Univariate analysis showed that there was a certain correlation between age, length of hospital stay, Glasgow coma scale (GCS), American Society of Anesthesiologists Physical Status (ASA-PS) classification, Injury severity score (ISS), prehospital tracheal intubation, hypotension, hypoxia, pupillary responsiveness, midline shift, basilar cisterna status, traumatic subarachnoid hemorrhage (tSAH), D-Dimer, prothrombin time activity (PTA), glucose, hemoglobin, K +, Cl -, Ca 2+, HCO -, creatinine, albumin, lactic acid, platelet, lymphocyte, systemic immune-inflammation index (SII), NLR, lymphocyte-to-monocyte ratio (LMR) and unfavorable prognosis of msTBI patients at 6 months after injury ( P<0.05 or 0.01). The ROC curve of single variable showed that GCS (AUC=0.82), ISS (AUC=0.81), pupillary responsiveness (AUC=0.76), basal cistern status (AUC=0.73) and NLR (AUC=0.73) had good predictive validity. The results of the correlation heatmap showed that there was a significant correlation and collinearity among the continuous variables, while no collinearity was found between ISS and NLR. Fourteen potential predictors selected by Lasso regression were included in multivariate Logistic regression analysis and its results showed that age ( OR=0.86, 95% CI 1.38, 5.19), GCS 6-8 points ( OR=3.13, 95% CI 1.06, 9.27), GCS 3-5 points ( OR=12.36, 95% CI 2.81, 54.27), ISS ( OR=3.68, 95% CI 1.38, 9.80), pupillary responsiveness ( OR=2.45, 95% CI 0.85, 7.07), and NLR ( OR=2.62, 95% CI 1.52, 4.51) were identified as the independent risk factors for unfavorable prognosis of msTBI patients at 6 months after injury ( P<0.05 or 0.01). The multivariate Logistic regression equation was Logit [P/(1-P)]=0.066×"age"+ 1.474×"GCS 6-8"+2.357×"GCS 3-5"+0.066×"ISS"+0.965×"absence of pupillary light reflex"+0.194×"NLR"-10.704. In the internal verification of random split of data, the AUC value of the model was 0.93 (95% CI 0.89, 0.96) in the training group and 0.93 (95% CI 0.89, 0.97) in the verification group. In the internal verification of non-random split, the AUC value was 0.94 (95% CI 0.91, 0.97) in the training group and 0.93 (95% CI 0.89, 0.97) in the verification group. The calibration curve and H-L test showed that the model had good calibration ability ( P>0.5). The results of DCA showed that the application of the nomogram would increase the net benefit of the patients (risk threshold probability of 0.0-0.8). Compared with the conventional model (AUC=0.90), inclusion of NLR model (AUC=0.93) enhanced the warning effectiveness. Conclusions:Age, GCS, ISS, pupillary responsiveness and NLR are independent risk factors affecting unfavorable prognosis in msTBI patients at 6 months after injury, based on which the nomogram constructed can better predict the clinical outcome of msTBI patients.

Femoral head fracture combined with posterior hip dislocation is a serious traumatic condition. Conservative treatment has a long time of bed rest, and may cause muscle apraxia atrophy, hypostatic pneumonia, deep vein thrombosis of the lower limbs, or pulmonary embolism, which has poor clinical efficacy. Therefore, surgical treatment is the first choice for femoral head fracture combined with posterior hip dislocation. The direct anterior approach of the hip can better expose Pipkin type I and type II femoral head fractures without the need to dislocate the hip completely. However, the disadvantage is that it destroys the structural integrity of the anterior hip joint, which increases the risk of femoral head necrosis and heterotopic ossification to a certain extent. The medial approach can also be chosen for Pipkin type I and II fractures, but it is important to avoid damaging the integrity of the fascial layer, some small vascular branches can be ligated, and injury to the medial rotary femoral artery should be avoided. The lateral approach is considered to be an effective treatment for Pipkin type III fractures, but there is limited exposure of the posterior acetabular injury and a risk of injury to the superior gluteal vessels and nerves, which may be secondary to adductor weakness postoperatively. The posterior approach is the main surgical approach for type IV Pipkin fracture. The classic posterior lateral approaches mainly include the Kocher - Langenbeck approach and the Ganz surgical dislocation approach. The Kocher - Langenbeck approach does not destroy the abductors and is particularly suitable for patients with posterior hip dislocation and difficult to reposition. Ganz surgical approach protects the blood supply of the medial femoral circumcator artery, so the incidence of femoral head necrosis is low. It can achieve all-round visualization of the femoral head and acetabulum, comprehensively evaluate the lesions of the femoral head and acetabulum, and find the occult injuries missed in imaging examinations..

Objective To investigate the resistance level of Aedes albopictus to commonly used insecticides in Jinshan District, Shanghai, to provide a reference for standardizing the use of insecticides. Methods The larval dipping test was used to detect the resistance of Ae. Albopictus larvae to five kinds of insecticides, the SPSS 18.0 software was utilized to calculate the toxic regression equation and the median lethal concentration (LC50) of insecticides on the larvae. The resistance level was determined by evaluating the 24-hour mortality of adult Ae. Albopictus exposed to diagnostic doses of commonly used insecticides with the adult mosquito contact tube method. Results In 2018 and 2019, Ae. Albopictus larvae in the Jinshan District of Shanghai displayed moderate and high resistance to beta-cypermethrin, with resistance ratios of 25.03 and 65.96 folds respectively; high resistance to deltamethrin, with resistance ratios of 57.25 and 211.75 folds respectively; high resistance to permethrin, with resistance ratios of 46.17 and 243.36 folds. In 2018, 2019, 2021, and 2023, they showed moderate to high resistance to temephos with resistance ratios of 19.55, 23.94, 53.48, and 22.12 folds respectively. In 2021 and 2023, moderate resistance to fenitrothion was observed, with resistance ratios of 30.04 and 12.54 folds respectively. Adult Ae. Albopictus adults exhibited resistance to 0.03% deltamethrin, 0.07% lambda-cyhalothrin, 0.4% permethrin, and 0.08% beta-cypermethrin, with mortality rates ranging from 17.20% to 49.67% in 2021 and 2023. Potential resistance was observed to 0.7% lambda-cyhalothrin and 0.2% fenitrothion, with mortalities of 97.48% and 83.74% respectively. Sensitivity was noted to 0.05% propoxur with a mortality rate of 100.00%. Conclusions Ae. Albopictus in the Jinshan District, Shanghai, has developed varying resistance levels to different types of insecticides, including pyrethroids and organophosphates. It is recommended to strengthen the dynamic monitoring of the resistance of Ae. Albopictus and implement comprehensive prevention and control measures with a focus on environmental management, scientifically and rationally selecting hygienic insecticides to delay and mitigate the emergence of resistance.

Objective:In order to determine the development potential of human embryos in vitro, amino acid and carnitine levels were measured in the culture medium of different grades of early human embryos. Methods:From the infertile couples who received in vitro fertilization-embryo transfer treatment in the Department of Reproductive Medicine of Linyi People′s Hospital from June 2022 to December 2022, the age of the women was defined as 25-35 years old [31.5(26.5, 33.25)] with 8-20 eggs, 126 cultured cells and embryos of the third day were randomly collected from infertile couples. They were divided into three groups according to the morphological level of the corresponding embryos: excellent, neutral and poor. Amino acids and L-carnitines levels in culture medium were detected by liquid chromatography-mass spectrometry (LC-MS). Using analysis of variance to compare differences among groups, correlation analysis, factor analysis was performed to analyze the association between the levels of amino acids and L-carnitines and development potential of early human embryos.Results:The value of Methionine/Phenylalanine was found statistically different among superior embryo (3.09±1.67), moderate embryo (4.00±1.19) and inferior embryo (4.99±2.04). The difference between the three groups was statistically different ( F=7.09, P<0.05): superior embryo vs moderate embryo ( t=-0.91, P<0.05), superior embryo vs inferior embryo ( t=-1.91, P<0.05), moderate embryo vs inferior embryo ( t=-0.99, P<0.05). Among different amino acids, Phe had the strongest positive correlation with Tyr ( r=0.99, P<0.01). Among different carnitines, C 8/C 10 has the strongest positive correlation with C 5DC+C 6OH/C 16( r=0.44, P<0.01). The weight value of leucine (isoleucine), arginine, valine/phenylalanine, glycine, tyrosine and carnitine(C 5DC+C 6OH)/C 8 calculated by the least square fitting model is 2.22, 1.99, 1.65, 1.54, 1.21 and 1.15 respectively. Conclusion:Leucine, arginine, valine/phenylalanine, glycine, tyrosine and carnitine (C 5DC+C 6OH)/C 8 in embryo culture medium were significantly correlated with the levels of early human embryos in vitro.

Objective To determine the clinical benefits of internal mammary sentinel lymph node biopsy (IM?SLNB) acquired by breast cancer patients with clinically positive axillary lymph node ( ALN), and further optimize the IM?SLNB indications. Methods All primary breast cancer patients with clinically positive ALN from February 2014 to September 2017 were prospectively recruited in this study.IM?SLNB was performed under the guidance of the modified injection technique. The success rate and visualization rate of IM?SLNB, metastatic rate of internal mammary sentinel lymph node ( IMSLN) and its related factors were analyzed, and the clinical benefits were accessed according to the current guidelines. Results Among 126 patients, all of 94 patients ( 74.6%) who showed internal mammary drainage successfully underwent IM?SLNB. The incidence of internal mammary artery bleeding and pleural lesion were 4.3%( 4／94) and 9.6%(9／94), respectively. The metastatic rate of IMSLN was 38.3%( 36／94), which was significantly associated with the number of positive ALN (P＜0.001) and tumor size (P＝0.024).The lymph node staging of 94 patients who underwent IM?SLNB was more accurate. Among them, 36 cases with positive IMSLN underwent internal mammary radiotherapy (IMRT), while the other 58 cases with negative IMSLN avoided radiotherapy. Conclusions IM?SLNB should be routinely performed in patients with positive ALN. IM?SLNB can provide more accurate staging and guide tailored IMRT to benefit more breast cancer patients.
