Actitudes desde la clase social baja hacia la clase social alta: el papel del contacto y la ansiedad intergrupal

Introducción: el contacto intergrupal es un buen predictor de las actitudes positivas hacia otros grupos, relación que podría ser explicada por una menor ansiedad intergrupal. Estas asociaciones han sido analizadas entre distintos grupos, como la nacionalidad o la religión. Sin embargo, el contacto y las actitudes entre clases sociales han sido escasamente explorados. Por este motivo, analizamos el efecto mediador de la ansiedad intergrupal sobre la relación entre el contacto intergrupal y las actitudes positivas desde las personas de la clase social subjetiva baja hacia las de clase social subjetiva alta. Esperamos una relación positiva entre contacto (cantidad y calidad) y actitudes positivas, con la mediación de una menor ansiedad intergrupal. Método: en una muestra chilena no representativa (N = 118), realizamos análisis de regresiones para evaluar nuestra hipótesis. Resultados: los resultados respaldaron nuestra principal hipótesis, la cantidad y calidad del contacto fueron asociados a actitudes más positivas hacia la clase social subjetiva alta, mediada por una menor ansiedad intergrupal. Conclusiones: discutimos las implicancias para las relaciones entre clases sociales y las limitaciones asociadas a la muestra y la evaluación de la clase social.

Introduction: Intergroup contact is a good predictor of positive attitudes towards other groups, relationships that could be mediated by lower intergroup anxiety. These associations have been analyzed among different groups, such as nationality or religion. However, contact and attitudes among social classes have been scarcely explored. For this reason, we analyzed the mediator effect of intergroup anxiety on the relationship between intergroup contact and positive attitudes from people of lower subjective social class to those of higher subjective social class. We expected a positive relationship between contact (quantity and quality) and positive attitudes, with the mediation of lower intergroup anxiety. Method: In a non-representative Chilean sample (N = 118), we conducted regressions analyses to evaluate our hypothesis. Results: the results supported our main hypothesis, contact quantity and quality were associated with more positive attitudes toward individuals of higher subjective social class, mediated by lower intergroup anxiety. Conclusions: we discussed the implications for relationships among social classes and the limitations associated with the sample and assessment of the social class.

Eating self-regulatory skill, diet quantity, and diet quality of Malaysian healthcare university students: A cross-sectional study

@#Introduction: The ability to self-regulate eating can improve health. This study aimed to determine the relationship between eating self-regulatory skills, diet quantity, and diet quality among Malaysian university students. Methods: This cross-sectional study involved 132 university students. Eating self-regulatory skill was assessed using the Self-Regulation of Eating Behaviour Questionnaire (SREBQ). Dietary intakes from two 24-hour dietary recalls were used to assess diet quantity and quality. Diet quantity was measured as energy and macronutrient intakes, analysed using NutritionistPro. Diet quality was measured using the Malaysian Healthy Eating Index (M-HEI). The relationship between eating self-regulatory skills, diet quantity, and diet quality were evaluated using tests for differences between means and multiple linear regression. Results: Male participants (n=47) consumed more energy than female participants (n=85) (Male: 1850±570 kcal/day, Female: 1596±567 kcal/day, p=0.015). Participants from the Nutrition and Dietetics (N&D) course (n=49) had better M-HEI scores than participants from other health courses (n=83) (N&D course: 52.7±10.5, non-N&D course: 47.2±10.7, p=0.005). The predictors of energy intake were gender (β=-0.193, p=0.023) and SREBQ score (β=- 0.223, p=0.009). Being female and having higher eating self-regulatory skills were associated with lower energy intake. The predictors of diet quality were university course (β=0.240, p=0.005) and SREBQ score (β=0.181, p=0.033). Studying N&D and having higher eating self-regulatory skills were associated with higher M-HEI scores. Conclusion: Higher self-regulation of eating behaviour score is a factor that contributes to lower daily energy intake and higher diet quality score.

Experience of quantity and quality of DNA and RNA extraction from limited pediatric blood samples: A comparative analysis of automated and manual kit-based method

Introduction: Optimal DNA and RNA quantity and purity is essential for downstream molecular biology experimentation and to avoid re-processing of sample. Despite availability of different kits and automated systems for nucleic acid isolation there is limited data on their performance evaluation, more so with pediatric blood samples, that are usually compromised in quantity. Hence, we evaluated the performance of automated QIAcube platform using pediatric blood samples in parallel with manual Qiagen extraction kits. Materials and Methods: A total of 500 samples were analyzed based on groups of PBMC and direct blood input. The isolated DNA and RNA were surveyed for quantity and quality tests by spectrophotometric and downstream analysis. Results: There was no significant difference in the DNA quantity (ng/ul) between manual and automated method based on similar sample input but quality (260/280) was significantly better with the QIAcube platform when direct blood and or PBMCs were used for extraction respectively (1.82 ± 004 Vs. 1.84.002; P-0.000008 and 1.859 ± 005 Vs. 1.843 ± 0.003; P-0.02). Moreover, the standard error mean was low for both quantity and quality in the QIAcube method suggesting uniformity. Comparison of quality assessment by spectrophotometer and qubit fluorimeter showed that QIAcube sheared DNA less (P- 0.038) as compared to manual method (P-0.013). Also, time taken to process the samples in QIAcube was 23% less than the kit-based method. Conclusion: Overall analysis of QIAcube platform suggests that it yields more better, uniform, and less-sheared quality of nucleic acid in a relatively less time as compared to manual extraction kits.

The content ranges of mangiferin， baicalin， glycyrrhizic acid， timosaponin BⅡ， and the sum of protoneodioscin and protodioscin in 15 batches of benchmark samples of Erdongtang were 0.14%-0.23%， 2.40%-3.37%， 0.07%-0.44%， 0.43%-0.95%， and 0.15%-0.47%， the transfer rate ranges of them were 33.90%-52.15%， 84.46%-105.61%， 22.59%-93.86%， 38.07%-61.43%， and 53.28%-96.11%， respectively. ConclusionThe consistencies of transfer rate of mangiferin， baicalin， timosaponin BⅡ and the sum of protoneodioscin and protodioscin （except glycyrrhizic acid） between decoction pieces and benchmark samples of Erdongtang are good， indicates that the transfer rates of 4 index components are stable during the preparation process of benchmark samples， which can provide data support for research and development of the compound preparation of this formula.

Expert consensus on the bone augmentation surgery for alveolar bone defects / 口腔疾病防治

@#Alveolar bone is an important anatomic basis for implant-supported denture restoration, and its different degrees of defects determine the choices of bone augmentation surgeries. Therefore, the reconstruction of alveolar bone defects is an important technology in the clinical practice of implant restoration. However, the final reconstructive effect of bone quality, bone quantity and bone morphology is affected by many factors. Clinicians need to master the standardized diagnosis and treatment principles and methods to improve the treatment effect and achieve the goal of both aesthetic and functional reconstruction of both jaws. Based on the current clinical experience of domestic experts and the relevant academic guidelines of foreign counterparts, this expert consensus systematically and comprehensively summarized the augmentation strategies of alveolar bone defects from two aspects: the classification of alveolar bone defects and the appropriate selection of bone augmentation surgeries. The following consensus are reached: alveolar bone defects can be divided into five types (Ⅰ-0, Ⅰ-Ⅰ, Ⅱ-0, Ⅱ-Ⅰ and Ⅱ-Ⅱ) according to the relationship between alveolar bone defects and the expected position of dental implants. A typeⅠ-0 bone defect is a bone defect on one side of the alveolar bone that does not exceed 50% of the expected implant length, and there is no obvious defect on the other side; guided bone regeneration with simultaneous implant implantation is preferred. Type Ⅰ-Ⅰ bone defects refer to bone defects on both sides of alveolar bone those do not exceed 50% of the expected implant length; the first choice is autologous bone block onlay grafting for bone increments with staged implant placement or transcrestal sinus floor elevation with simultaneous implant implantation. Type Ⅱ-0 bone defects show that the bone defect on one side of alveolar bone exceeds 50% of the expected implant length, and there’s no obvious defect on the other side; autologous bone block onlay grafting (thickness ≤ 4 mm) or alveolar ridge splitting (thickness > 4 mm) is preferred for bone augmentation with staged implant placement. Type Ⅱ-Ⅰ bone defects indicate that the bone plate defect on one side exceeds 50% of the expected implant length and the bone defect on the other side does not exceed 50% of the expected implant length; autologous bone block onlay grafting or tenting techniques is preferred for bone increments with staged implant implantation. Type Ⅱ-Ⅱ bone defects are bone plates on both sides of alveolar bone those exceed 50% of the expected implant length; guided bone regeneration with rigid mesh or maxillary sinus floor elevation or cortical autologous bone tenting is preferred for bone increments with staged implant implantation. This consensus will provide clinical physicians with appropriate augmentation strategies for alveolar bone defects.

Mechanism of hepatotoxicity induced by ethanol extract of Dysosma versipellis based on "quantity-weight-evidence" network toxicology / 中国中药杂志

In this study, the toxicological/pharmacological research method of "quantity-weight-evidence" network was first proposed and practiced to supplement the existing methodology of network toxicology. We transformed the traditional qualitative network into a quantitative network in this study by attributing weights to toxic component content and target frequency, which improved the reliability of data and provided a research idea for the systematic safety evaluation and toxicological research of Chinese medicinal herbs. Firstly, 50% ethanol extract of Dysosma versipellis(DV) was administrated to rats via gavage and the potential hepatotoxic components were identified by serum pharmacochemistry. Then, the component targets were obtained from SwissTargetPrediction, PharmMapper and other online databases, and the target weights were given according to the relative content of components and target fishing frequency. Meanwhile, the targets of hepatotoxicity were predicted from online databases such as Comparative Toxicology Database(CTD) and GeneCards. Subsequently, protein-protein interaction analysis and KEGG pathway enrichment were performed with the STRING database. Finally, the quantitative network of "toxic components-weighted targets-pathways" was constructed. Eleven potential toxic compounds were predicted, including podophyllotoxin, podophyllotoxone, deoxypodophyllotoxin, and 6-methoxypodophyllotoxin. A total of 106 hepatotoxic targets and 65 weighted targets(e.g., Cdk2, Egfr, and Cyp2 c9) were identified. The results of Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment showed that these targets could act on PI3 K-AKT, MAPK, and Ras signaling pathways to play a role in inflammatory response and oxidative stress. However, traditional network toxicology showed that 51 targets such as AKT1, Alb, and Stat3 may lead to hepatotoxicity by mediating inflammation and cell proliferation. In conclusion, we proposed "quantity-weight-evidence" network toxicology in this study and used it to study the mechanism of DV-induced hepatotoxicity in rats. This study confirms the feasibility of this new methodology in toxicological evaluation and further improves the systematic evaluation of the safety of Chinese medicinal herbs.

Quality control mode based on engineering quality view of Chinese medicine pharmacy / 中国中药杂志

Due to the characteristics of confusing varieties of Chinese medicinal materials, different sources, complex chemical composition, non-standard preparation process, and non-standard pharmaceutical equipment, the quality of Chinese medicinal preparations is difficult to be controlled and evaluated effectively under the current quality control mode and method of Chinese medicinal preparation. The present study proposed an engineering quality view of Chinese medicine pharmacy and a strategy to control the quality of Chinese medicinal preparations based on the current situation. The "overall, dialectical, and dynamic" multi-factor engineering quality view, covering original medicinal materials, preparation technologies, pharmaceutical equipment, and Chinese medicinal preparations, ensures the traceable process, measurable procedures, and feedback quality. The quality control mode of Chinese medicinal preparation with controllable sources, standardized preparation technologies, green pharmaceutical equipment, and intelligent manufacturing is built up.

Evaluation of the average pulp cavity volume of primary second molar and canine for obturation of a single primary tooth A preliminary cone-beam computed tomographic study

Objective: Metapex/Vitapex is one of the most commonly used obturating materials in pediatric dental practice in recent times. It is available in a premixed syringe which poses numerous practical difficulties. This study aimed to calculate the root canal volume of maxillary and mandibular canine and second molar using cone-beam computed tomography (CBCT) to determine the quantity/grams of obturation material to obturate a single tooth (mass = density × volume). Materials and Method: This nonrandomized clinical trial is comprised of two parts. The first part involved calculation of average root canal volume using CBCT which was used to calculate the quantity/grams of obturating material. This predetermined quantity was used to obturate primary mandibular second molars and canines, and the quality of obturation was assessed. Results: Assessment of quality of obturation showed optimum length obturation in 53.33% primary second molars and 66.66% primary canines. Conclusion: It can be inferred that even with the use of exact predetermined quantity/grams of obturating material, optimum quality obturation could be achieved, thus avoiding wastage, preventing cross contamination, and simultaneously offering good clinical results. Hence, this study opens further gateways to device ampules containing predetermined mass of obturating material for a single use for obturation of a single primary tooth.

Analysis on quality value transfer of substance benchmarks of Zhenwu Decoction / 中国中药杂志

By preparing 15 batches of Zhenwu Decoction substance benchmarks,the characteristic map,index component content and paste-forming rate were determined to define the peak attribution,similarity range,paste-forming rate range,paeoniflorin and6-gingerol content range and transfer rate range. The similarity between the substance benchmark characteristic map and the control map R generated from the 15 batches of substance benchmarks was higher than 0. 970. There were 19 characteristic peaks in total. By further summarization of the characteristic peaks,it could be seen that tuckahoe had 3 characteristic peaks,white peony root had 10 characteristic peaks,atractylodes had 3 characteristic peaks,ginger had 1 characteristic peak,and Aconite root had 3 characteristic peaks; among them,white peony root and aconite root had 1 common peak. The contents and transfer rates of the 15 batches were0. 50%-0. 93 and 16. 11%-26. 20%; those for 6-gingerol were 0. 018 2%-0. 033 9% and 13. 16%-24. 10%,respectively. The pasteforming rate ranged from 10. 00% to 14. 85%. In this study,the transfer process of substance benchmark value of classic formula Zhenwu Decoction was analyzed based on the characteristic map,the paste-forming rate and the content of the index components; a scientific and stable substance benchmark quality evaluation method was preliminarily established to provide a basis for subsequent development of classic formula Zhenwu Decoction and quality control of relevant preparations.

Analysis of Statins Use in a Shanghai Hospital under the Policy of Drug Quantity Purchasing / 中国药房

OBJECTIVE：To investigate the effects of the third batc h of Shanghai drug quantity purchasing and national “4+7” drug quantity purchasing in a Shanghai hospital and its impact on the use of statins. METHODS ：Consumption amount （tablets） and sum of statins were collected from information system of this hospital before （Feb. 10th-Aug. 31th，2018）and after （Sept. 1th，2018-Mar. 19th，2019）the implementation of the third batch of Shanghai drug quantity purchasing ，after the implementation of national “4+7”drug quantity purchasing （Mar. 20th-Oct. 9th，2019）. The defined drug frequency （DDDs）and average defined daily cost （DDC） of above 3 periods were calculated according to drug defined daily dose （DDD） recommended by New Pharmacology and related drug instructions ，so as to analyzethe influence of the third batch of Shanghaidrug quantity purchasing and national “4+7”drug quantity purchasing on the use of statins in this hospital and predict the market share trend of each specification in this hospital. RESULTS & CONCLUSIONS ：Before the implementation of the third batch of Shanghaidrug quantity purchasing，there were 5 varieties and 8 specifications of statins in this hospital ；after the implementation of quantity purchasing ，it was adjusted to 5 varieties and 9 specifications. The amount of Simvastatin tablets was small in general ，and its consumption sum also continued to decline after the implementation of quantity purchasing. The amount of Rosuvastatin calcium tablets accounted for 49.49％ before the implementation of quantity purchasing ，ranking the first ；after the implementation of 3 batches of Shanghai drug quantity purchasing ， the amount proportion decreased to Δ 基金项目：上海市科学技术委员会科研计划项目（No.19ZR1450- 600） below 30％，and consumption sum proportion decreased from ＊本科 。研究方向 ：医药市场研究与分析 。电话 ：021- 37.82％ to 18.77％；after the implementation of national “4+ 54237308。E-mail：2123398711@qq.com 7”drug quantity purchasing ，the consumption sum proportion # 通信作者 ：副主任药师 ，博士。研究方向 ：临床药学 。电话： continued to decline to 17.38％ .The amount of Atorvastatin 021-65690520。E-mail：Hongjun.chen@tongji.edu.cn calcium tablets increased significantly after the implementation 中国药房 2021年第32卷第2期 China Pharmacy 2021Vol. 32 No. 2 ·247· of the thi rd batch of Shanghaidrug quantity purchasing ，from 41.55％ to 54.09％，and decreased slightly after the implementation of the national “4+7”drug quantity purchasing ，but the amount proportion was still as high as 53.06％，ranking the first ；before and after the implementation of quantity purchasing ，the proportions of its consumption sum were ranked the first ，which remained at about 50％，being 52.87％，61.18％ and 46.50％，respectively. Compared with the amount before the implementation of the third batch of Shanghaidrug quantity purchasing ，the amount of its generic drugs increased by 40.32％，but the consumption sum decreased by 78.18％. Any one type of Pravastatin sodium tablets and Pitavastatin calcium tablets was not selected ；the proportion of them was increased continuously ，but the overall proportion was relatively small. The price of statins decreased significantly after included in quantity purchasinglist. It is expected that the market share of simvastatin in thise hospital will continue to shrink ，and that of atorvastatin may continue to expand. Due to more adverse reactions ，rosuvastatin has limited room to expand ，and pravastatin accounts for a small proportion ，but there is still a demand for patients. Because pitavastatin is a new drug ，its application in this hospital needs more clinical data support.

Investigation on Synergistic Effect between Centralized Drug Quantity Purchase Policy and Medical Insurance Reimbursement System / 中国药房

OBJECTIVE：To investigate the synergistic effect and deficiencies between centralized drug quantity purchase policy and medical insurance reimbursement system ，and to provide feasible suggestion to further improve its synergistic effect. METHODS：The literature analysis method and policy evaluation method were adopted to expounds the direct and indirect synergistic effect between the current centralized drug quantity purchase policy and medical insurance reimbursement system in China，and analyze the existing problems so as to put forward the feasible suggestions. RESULTS & CONCLUSIONS ：The centralized drug quantity purchase policy had a direct impact on the payment mode of medical insurance reimbursement system in technical level ，performance evaluation in effect level and process control in management level. The indirect synergy included ： centralized drug quantity purchase policy could promote the adjustment of drug supply security system to adapt to the reform of medical insurance payment ；it could adjust the pharmaceutical market ，and affect the reform of medical insurance reimbursement system. The disadvantages were as follows ：the varieties of selected drugs was still narrow ，and there was room for further improvement in purchasing scope and medical insurance fee reduction ；“one-size-fits-all”payment standard for unselected drug might weaken pharmaceutical companies ’enthusiasm for generic drug research and development. Therefore ，the next step is to significantly expand the variety and scope of procurement ，and appropriately liberalize the medical insurance payment restrictions for drugs with fewer varieties ；coordinate medical insurance reimbursement policies and procurement programs ，and improve the rationality and perfection of medical insurance payment ；guide the medical institutions to change the concept from “price-based medical treatment ”to“value-based medical treatment ”，take into account the interests of all parties in the market ，so as to form a comprehensive coordination adjustment mechanism of drug price and medical insurance reimbursement system.

Surgical methods and clinical efficacy of different types of cesarean scar pregnancy / 中国基层医药

Objective:To compare surgical methods and clinical efficacy among different types of cesarean scar pregnancy (CSP).Methods:A total of 158 patients with CSP who received treatment in Yuncheng Central Hospital from January 2016 to June 2019 were included in this study. According to Expert Consensus on Diagnosis and Treatment of Cesarean Scar Pregnancy (2016 version), type I CSP was found in 55 patients, type II in 86 patients and type III in 17 patients. These patients were divided into groups A (ultrasound-guided suction curettage), B (uterine artery chemoembolization + ultrasound-guided suction curettage) and C (laparoscopic scar pregnancy lesion resection + scar repair) according to different surgical methods. The amount of intraoperative blood loss, the difference in human chorionic gonadotropin (HCG) level between before and after surgery, the time to postoperative HCG level returning to normal level, menstruation recovery, and re-pregnancy were compared between groups.Results:The amount of intraoperative blood loss in the groups A, B and C was (43.33 ± 72.31) mL, (34.41 ± 17.16) mL, (65.71 ± 70.52) mL, respectively. There was significant difference between groups ( F = 8.51, P = 0.014]. The difference in HCG level between before and after surgery in groups A, B and C was (0.64 ± 0.18), (0.79 ± 0.10), (0.76 ± 0.19), respectively. There was significant difference in the difference in HCG level between groups ( F = 19.21, P < 0.001). There was significant difference in the incidence of postoperative menstrual volume reduction between group B and the other two groups ( χ2 = 6.73, P = 0.003). After surgery, intrauterine pregnancy occurred in 12 patients, including 8 patients in group A (type I CSP in 2 patients, type II CSP in 3 patients, type III CSP in 3 patients), 4 patients in group B (type I CSP in 3 patients, type II CSP in 1 patient). Finally, full-term fetus delivery by cesarean section was performed in 6 patients (4 patients in group A and 2 patients in group B). Conclusion:Uterine artery chemoembolization combined with uterine curettage had less blood loss, during surgery and leads to an obvious decrease in HCG level, but it can result in reduction of menstrual volume. Ultrasound-guided suction curettage is preferred for type I and type II CSP. Balloon compression can be used to stop bleeding if massive bleeding occurs. Laparoscopic scar pregnancy lesion resection plus scar repair is recommended for type III CSP.

Experimental observation of effects of acupoints, cone numbers and durations of moxibustion with different moxibustion methods on skin surface and inside temperature / 针灸推拿医学（英文版）

Objective: To observe the effects of acupoints, cone numbers and durations of moxibustion with different moxibustion methods on skin surface and inside temperature, and to provide references for the clinical standardization of moxibustion amount. Methods: The 42 big-ear white rabbits were divided into 6 groups according to the random number table method, a 1-cone direct moxibustion group, a 2-cone direct moxibustion group, a 3-cone direct moxibustion group, a 1-cone herbal cake-partitioned moxibustion group, a 2-cone herbal cake-partitioned moxibustion group, and a 3-cone herbal cake-partitioned moxibustion group, with 7 rabbits in each group. Shenque (CV 8), Shenshu (BL 23) and Zusanli (ST 36) were used in each group, but the moxibustion methods, cone numbers and durations of moxibustion were different. Rabbits in each group received moxibustion once every other day for 5 times in total. During the intervention, a thermoelectricity coupled probe and a temperature recorder were used to record the real-time acupoint skin temperature and the temperature at different time points, so as to observe, analyze and process the real-time changes in the temperature difference between the surface and inside of acupoint skin. Results: For herbal cake-partitioned moxibustion, the best temperature for cone changing was (46.38±0.51) ℃ when the highest surface temperature was (49.20±0.52) ℃; the multi-factor comparison of acupoint × cone number × time and acupoint × moxibustion method × time showed that time × acupoint, time × moxibustion method and cone number × acupoint had interactive effects (all P<0.05). Comparing skin temperature differences between different cone numbers at the same acupoint, Shenque (CV 8) on the 1st and the 5th days, Shenshu (BL 23) on the 3rd and the 7th days, Zusanli (ST 36) on the 1st and the 9th days of experiment showed statistically significant differences (all P<0.05). The skin temperature comparison of different moxibustion methods at the same acupoint all had statistical differences (all P<0.05), except for Shenque (CV 8) before moxibustion, Shenshu (BL 23) before moxibustion and on the 5th day; Zusanli (ST 36) only showed statistical differences on the 5th and 7th days (both P<0.05). The skin temperature differences of different acupoints after moxibustion in the 1-cone, 2-cone and 3-cone groups were statistically different (all P<0.05); direct moxibustion and herbal cake-partitioned moxibustion at different acupoints were all statistically different (all P<0.05). Conclusion: Cone changing temperature under the same specifications of herbal cake-partitioned moxibustion was confirmed. Temperature difference between surface and inside of different acupoint skin at the same maximum temperature was significantly different due to the cone numbers and moxibustion methods, which showed the highest at Shenshu (BL 23), the second at Shenque (CV 8), and the lowest at Zusanli (ST 36). The influence of acupoint factor should be considered to determine the quantitative indicators of moxibustion.

Comparison of Immediate Effects on Usage of Dual Polymer Artificial Tears on Changes in Tear Film Characteristics

@#Introduction: This study aimed to evaluate the short-term efficacy of two comparable formulation of dual-polymer artificial tears: Systane Hydration preservative (SH) and non-preservative (SHUD) in 60 minutes observation period compared to normal saline. Methods: Fifty participants involved in this prospective, double-masked randomised study. Viscosity and pH of artificial tears were evaluated using rheometer and digital pH-meter prior to tear film assessment. Tear break-up time (TBUT) and tear meniscus height (TMH) were measured at baseline, 5, 15 and 60 minutes after instillation. Tear ferning pattern (TFP) were compared between baseline and 60 minutes after instillation. One-way analysis of variance (ANOVA) and Independent T-test were used to evaluate the effects of SH and SHUD after instillation and comparison between each specific time-interval respectively. P-value of 0.05 was set as the level of significance. Results: The viscosity of SH and SHUD was 26.7cP and 32.73cP re-spectively with pH of 7.85 (SH) and 7.74 (SHUD). Both artificial tears showed significant increment in TBUT between baseline and 15 minutes (SH:5.82±1.063, p=0.01; SHUD:6.02±0.979, p<0.001), and 60 minutes (SH:6.22±0.616, p<0.001; SHUD:6.34±0.658, p<0.001). SHUD demonstrated significant increment in TMH at every measurement taken (0.1996±0.02449, p<0.001 at 5min, 0.2038±0.02276, p<0.001 at 15min and 0.2068±0.02094, p<0.001 at 60min). Likewise, in SH group, significant increment in TMH at 15 minutes (0.1994±0.02325, p<0.001) and 60 minutes (0.2012±0.02379, p<0.001) were noted.

Optimization practice of fixed number package management of medical consumables based on SPD management mode / 中华医院管理杂志

The fixed number package management of medical consumables is an important content of SPD management mode. In the process of medical low-value consumables management, hospitals are generally faced with the problems of frequent access and low matching between push quantity and actual use quantity, resulting in complicated access operations of medical staff, shortage or hoarding of consumables and so on. In order to reduce the times of taking and using consumables and improve the comfort of medical staff, the authors dynamically adjusted the content and push quantity of fixed number packages according to the historical use data. The results showed that the adjusted fixed number setting could significantly reduce the average daily access times of medical staff, and reduce the probability of out of stock and hoarding.

Study on determination and quantity transfer of multi index components in Wenjing Decoction / 中国中药杂志

Based on the textual research on literature, the key information of Wenjing Decoction were tested and identified, and 15 batches of lyophilized powder samples of Wenjing Decoction were prepared. The specific components, including paeoniflorin, glycyrrhizin, ginsenosides(Rg_1, Re and Rb_1), glycyrrhizic acid, and paeonol, were used as indexes to establish the HPLC method for quantitative evaluation, and the content ranges and transfer rates of these components were determined. The results showed that the contents of paeoniflorin, glycyrrhizin, ginsenosides Rg_1 + Re, ginsenoside Rb_1, glycyrrhizic acid, and paeonol in the 15 batches of samples were 0.62%-0.86%, 0.25%-0.76%, 0.14%-0.30%, 0.07%-0.21%, 0.63%-1.16%, and 0.09%-0.25%, respectively, and their transfer rates from the decoction pieces to the reference materials were 14.99%-19.42%, 28.11%-40.93%, 25.92%-61.88%, 25.03%-64.06%, 23.43%-35.53%, and 5.34%-10.44%, respectively. The consistency of the transfer rates between batches indicated that the preparation process was stable. It is suggested that the contents of paeoniflorin, glycyrrhizin, ginsenosides Rg_1 + Re, ginsenoside Rb_1, glycyrrhizic acid, and paeonol in Wenjing Decoction should not be less than 0.52%, 0.35%, 0.15%, 0.10%, 0.63%, and 0.12%, respectively. In this study, we determined the contents and analyzed the quantity transfer process of the index components in Wenjing Decoction, which can provide a basis for the follow-up development of Wenjing Decoction and the quality control of related preparations.

Role of Non-stress Test in Antenatal Fetal Assessment in High-risk Pregnancy in Comparison with Normal Pregnancy

Background and Objectives: Non-stress test (NST) is one of the most widely used primary tests for the assessment of fetal well-being. It is a graphical recording of fetal heart activity and uterine contractions simultaneously and continuously when uterus is quiescent with fetal movements. It has been incorporated into biophysical profile system. It is simple, inexpensive, non-invasive, easily performed, and interpreted. Hence, it can be used to screen a large population as an outpatient department procedure. This study was done to observe the efficacy and diagnostic value of NST for antenatal surveillance and comparison of test results with mode of delivery and adverse perinatal outcome. Materials and Methods: A total of 100 high-risk (HR) pregnant women (study group – selected based on inclusion and exclusion criteria) and 100 low-risk (LR) pregnant women (control group) were randomly enrolled into study and followed up with NST from 32 weeks of gestation and repeated at appropriate intervals in cases of the HR group. Results: In the LR group, there was an increased incidence of intrapartum fetal death (IPFD), meconium-stained amniotic fluid (MSAF), and decreased liquor quantity in non-reactive (NR) subgroup compared to reactive NST (R-NST) subgroup. However, in the HR group, NR-NST was associated with significantly increased incidence of decreased liquor quantity, low Apgar score at 5 min of birth, and perinatal mortality compared to the R-NST subgroup. Although the statistical incidence of IPFD was not significant in the NR-NST subgroup compared to R-NST, it appeared clinically significant. MSAF incidence was not significant in these two NST result subgroups. Sensitivity, specificity, and negative predictive value of NST in the LR group were 100%, 81.8%, and 100%, respectively; likewise, in the HR group, they are 75%, 78.1%, and 98.7%, respectively, for perinatal mortality. Conclusion: NST is a valuable screening test for detecting fetal compromise in both HR and LR fetuses that may have a poor perinatal outcome. Predictive value of NST for perinatal mortality was higher in the LR group compared to the HR group though statistically was not significant.

Establishment and Application of Charge-by-dose Model for Pediatric Drugs in Our Hospital / 中国药房

OBJECTIVE：To establish c harge-by-dose model for pediatric drugs in our hospital ，so as to provide reference for reducing patients ’expenditure，saving medical insurance funds and reducing drug proportion. METHODS ：Since June 2019，a total of 12 kinds of drugs with heavy usage ，high price and large savings in our hospital were selected to establish pediatric charge-by-dose list. The drugs included in the list were split into 1/2 or 1/5 small-sized drug for charge-by-dose model. The process，quality control standards and surplus （loss）drug record of charge-by-dose model were formulated to coordinate the use of pediatric drugs between pharmacies and pediatric departments. The quantity and amount of drugs which were split ，and the drug proportion in pediatric departments were compared between charge-by-dose model and charge-by-unit model （theoretical value of dosage conversion in the same period ）during Jun.-Dec. 2019. RESULTS ：From Jun. to Dec. 2019，the quantities of split drugs each month with charge-by-dose model and charge-by-unit model were （3 346.43±734.73）and（6 821.71±1 468.81）；the amounts of split drugs each month with two models were （53 576.03±10 958.78）yuan and （112 642.75±21 308.77）yuan， respectively，with statistical significance （P＜0.05）. The drug proportion in four pediatric internal medicines departments and one neonatal medicine department had decreased to varying degrees. CONCLUSIONS ：Pediatric drug charge by dose can reduce the use and amount of drugs ，save medical insurance expenditures ，decrease the drug proportion of department.

Atomization Characteristics of Baicalin， Ursodeoxycholic Acid and Caffeic Acid in Tanreqing Inhalation Solution / 中国实验方剂学杂志

Objective:To investigate the effect of different angles of atomizer on the delivery rates and total delivery quantities of Tanreqing inhalation solution， so as to provide reference for the clinical use of this preparation. Method:Taking baicalin， ursodeoxycholic acid， caffeic acid as indexes， PARI Boy SX compression atomization inhaler （equipped with red core atomizing cup） and BRS2000 respiratory simulator were used， the effects of different angles of the atomizer （upper 15 degree， lower 15 degree， upper 30 degree， lower 30 degree， partial 15 degree， partial 30 degree， vertical） on the delivery rates and total delivery quantities of Tanreqing inhalation solution were investigated. The respiratory patterns of adults， children， infants and young children were selected to determine the delivery rates and total delivery quantities of three components in Tanreqing inhalation solution. Result:In the same atomization time， the delivery rates and the total delivery quantities of caffeic acid and ursodeoxycholic acid in Tanreqing inhalation solution were not significantly affected by the atomizer from different angles， but significantly affected baicalin. At the vertical angle， the delivery rate and total delivery quantity of baicalin were higher than the other angles. Under different respiratory modes， there were significant differences in the delivery rates and total delivery quantities of these three components in the inhalation solution. Compared with other respiratory modes， the delivery rates and total delivery quantities of baicalin， ursodeoxycholic acid and caffeic acid were the highest in the adult respiratory mode， with delivery rates of （555.5±16.61）， （226.3±6.54）， （26.1±0.32） μg·min-1 and total delivery quantities of （4 001.1±82.97）， （1 754.9±63.73）， （167.6±1.42） μg， respectively. Conclusion:The use angle of atomizer has a certain effect on the delivery rate and total delivery quantity of Tanreqing inhalation solution， so it is suggested that the vertical angle should be kept as far as possible in clinical use. Under the four respiratory patterns， the delivery rate and total delivery quantity of Tanreqing inhalation solution are different， suggesting that the atomization dose or atomization time should be adjusted according to the respiratory characteristics of the patients to ensure the safety and effectiveness of clinical medication.
