ObjectiveTo explore the mechanisms associated with Mahoniae Caulis alkaloids （MA） in ameliorating depression by network pharmacology， molecular docking， and animal experiments. MethodsThe component targets of MA were obtained through Swiss Target Prediction and TCMIP database. The depression targets were collected through TCMIP， Genecards， HPO， DrugBank and OMIM database. The depression targets were collected through TCMIP， Genecards， HPO， DrugBank and OMIM database. Protein-protein interaction （PPI） network was constructed by protein interaction analysis （STRING） database. Gene ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） analyses were performed through Bioinformatics （DAVID） database. The docking of components and targets was performed by AGFR. The mouse model of depression was established by intraperitoneal injection of corticosterone （CORT） once a day for 35 consecutive days. Sixty mice were randomly allocated into control （0.9% normal saline）， model （CORT， 20 mg·kg^-1）， positive control （fluoxetine hydrochloride， 3.6 mg·kg^-1）， and MA （10， 5， and 2.5 mg·kg^-1） groups. Each group was administrated with corresponding medicine or normal saline once a day for 28 consecutive days. The depression-like behavior of mice was observed. The pathological changes of prefrontal cortex in mice were observed by hematoxylin-eosin staining. Terminal deoxynucleotidyl dUTP transferase nick end labeling （TUNEL） was employed to observe the apoptosis of neurons in the prefrontal cortex. Enzyme-linked immunosorbent assay was employed to assess the serum levels of brain-derived neurotrophic factor （BDNF）， dopamine （DA）， 5-hydroxytryptamine （5-HT）， and norepinephrine （NE） in mice. The mRNA levels of cyclic adenosine monophosphate （cAMP） pathway-related factors and inflammatory factors were determined by Real-time PCR. Western blot was employed to determine the expression of cAMP pathway-related factors and connexin 43 （Cx43）. ResultsA total of 434 component targets and 545 depression targets were obtained， including 84 common targets， among which 10 core targets were screened out. GO analysis predicted 34 biological processes， 15 cell components， and 11 molecular functions. The KEGG pathways were mainly related to gap junction and cAMP signaling pathway. The core components had good binding affinity with the core targets. The results of animal experiments showed that compared with the control group， CORT prolonged the immobility time of mice in forced swimming and tail suspension tests （P<0.01）， lowered the serum levels of NE， BDNF， and 5-HT （P<0.05）， up-regulated the mRNA levels of nuclear factor-κB （NF-κB） and interleukin-6 （IL-6） in the brain tissue （P<0.05）， and down-regulated the mRNA levels of cyclic adenosine monophosphate effector binding protein （CREB） and BDNF （P<0.05） and the protein levels of protein kinase （PRKACA）， phosphorylation （p）-CREB/CREB， BDNF， and Cx43 （P<0.05） in the brain tissue. Compared with the model group， high-dose MA reduced the immobility time of mice in forced swimming （P<0.05） and tail suspension （P<0.01） tests， raised the serum levels of NE， BDNF， and 5-HT （P<0.01）， down-regulated the mRNA level of NF-κB （P<0.01）， and up-regulated the mRNA level of BDNF （P<0.01） and protein levels of PRKACA， p-CREB/CREB， BDNF， and Cx43 （P<0.05）. ConclusionMA alleviates the CORT-induced depressive behavior of mice. It may play an antidepressant role by regulating cAMP signaling pathway and gap junction pathway， improving synaptic plasticity and gap junction function， and reducing neuroinflammation.

GBA1 gene mutation is an important genetic risk factor for Parkinson’s disease (PD). This paper reports a case of a 43-year-old male PD patient carrying a rare heterozygous Thr408Met mutation in the GBA1 gene identified through whole-exome sequencing, leading to a diagnosis of GBA1-associated PD. The patient’s motor symptoms were primarily characterized by bradykinesia and rigidity, without significant cognitive decline. Treatment with low-dose levodopa combined with a dopamine agonist resulted in significant symptomatic improvement.

ObjectiveTo investigate effect of Maxing Shigantang and supplemented Guominjian decoction on symptoms and levels of inflammatory cytokines in induced sputum of children with cough variant asthma （CVA）. MethodA total of 118 CVA children who were treated in our hospital from January 2020 to January 2021 were enrolled and randomized into the control group and the observation group with the random number table method. Control group received routine western medicine and the observation group was treated by routine western medicine， Maxing Shigantang， and supplemented Guominjian decoction. In the one-month follow-up， the scores of cough and accompanying symptoms， levels of inflammatory cytokines ［interleukin-10 （IL-10）， interleukin-5 （IL-5）， tumor necrosis factor-α （TNF-α）， neutrophil， eosinophil］ in induced sputum， pulmonary function parameters ［forced vital capacity （FVC）， forced expiratory volume in one second （FEV₁）， FEV₁/FVC］， and treatment outcomes were compared between the two groups. Moreover， the frequency of acute asthma attacks during the three-month follow-up was also compared. ResultNo cases dropped out from this study. After treatment， the scores of cough and accompanying symptoms were decreased in both groups （P<0.05） and were lower in observation group than in control group （P<0.05）. After treatment， FVC， FEV₁， and FEV₁/FVC were raised in both groups and were higher in observation group than in control group （P<0.05）. The increase in the level of IL-10 along with the decrease in levels of IL-5， TNF-α， neutrophil， and eosinophil in induced sputum was found in both groups after treatment （P<0.05）， and observation group had higher level of IL-10 and lower levels of IL-5， TNF-α， neutrophil， and eosinophil than the control group （P<0.05）. The effective rate was 86.44% （51/59） in observation group， which was higher than the 69.49% （41/59） in control group （χ²=4.933， P<0.05）. No serious adverse reaction occurred in either group. The frequency of acute asthma attacks during the three-month follow-up was （1.09±0.18） in observation group， which was lower than the （2.83±049） in the control group （P<0.05）. ConclusionRoutine western medicine combined with Maxing Shigantang and supplemented Guominjian decoction can effectively and safely alleviate the airway inflammatory responses， control the clinical symptoms， improve pulmonary function， and reduce the frequency of acute recurrence in the treatment of CVA children.

Objective To analyze the mortality characteristics and trends and the cause-eliminated life expectancy of gastric cancer in Harbin City from 1987 to 2019. Methods Mortality data of residents with gastric cancer from 1987 to 2019 in Harbin was analyzed to describe the mortality characteristics and trends of gastric cancer. Abridged life table and cause-eliminated life table were applied to calculate life expectancy and cause-eliminated life expectancy. Average annual percentage change (AAPC) was calculated with Joinpoint 4.2 software to evaluate the trends of mortality and cause-eliminated life expectancy of gastric cancer. Results From 1987 to 2019, the crude mortality, ASMRC and ASMRW and the truncated rate (35-64) were 14.3/10⁵, 10.9/10⁵, 10.9/10⁵, and 13.5/10⁵, respectively. The ASMRC showed an obvious decreasing trend at an average annual rate of 2.9% from 1987 to 2019 (95%CI: -4.4%--1.4%). Significant decreasing trends were observed for males (AAPC=-3.0%, 95%CI: -4.4%--1.7%) and females (AAPC=-3.1%, 95%CI: -5.3%--0.9%). An obvious decreasing trend in the ASMRW was also observed. The truncated rate (35-64) showed a downward trend (AAPC=-2.8%, 95%CI: -3.1%--2.5%). The average life expectancy of residents from 1987 to 2019 in Harbin were 76.78 years (male: 74.41 years, female: 79.33 years). After eliminating the causes of death of gastric cancer, the life expectancy increased by 0.25 years (male: 0.31 years, female: 0.18 years). Significant decreasing trends were found in the proportion of gastric cancer in all malignant cancer cases (AAPC=-0.18%, 95%CI: -2.0%--1.7%). Conclusion The mortality of gastric cancer decreases gradually from 1987 to 2019 in Harbin. After eliminating the causes of death of gastric cancer, the life expectancy increases by 0.25 years. Therefore, prevention and control should be strengthened.

ObjectiveTo explore the correlation between dryness and energy metabolism of Atractylodis Rhizoma， and to analyze the difference of medicinal properties between Atractylodes lancea and A. chinensis. MethodA total of 110 healthy SD rats were randomly divided into 11 groups， including normal group， volatile oil of A. lancea 1-5 group （S1-S5 group， doses of 447， 473， 442， 489， 496 mg·kg^-1） and volatile oil of A. chinensis 1-5 group （N1-N5 group， doses of 197， 118， 281， 222， 185 mg·kg^-1）， the administration volume was 0.01 mL·g^-1 with intragastric administration for 21 days. Dryness effect of A. lancea and A. chinensis on rats was evaluated by comparing the body weight， drinking water volume， urine volume， whole blood viscosity and pathological sections of submandibular gland stained with hematoxylin-eosin （HE）. The expression of aquaporin 2 （AQP2） in rat kidney was measured by immunohistochemistry， the mRNA expressions of cytochrome C oxidase subunit 7A2 （COX7A2） and succinate dehydrogenase （SDH） complex subunit D （SDHD） in liver tissue were detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The contents of SDH， lactate dehydrogenase （LDH） and sodium ion-potassium ion-adenosine triphosphatase （Na⁺-K⁺-ATPase） in rat plasma were determined by colorimetry. The quality of A. lancea and A. chinensis was evaluated by coefficient of variation method， and Pearson correlation coefficient was used to analyze the correlation between dryness and energy metabolism. ResultCompared with the normal group， the amounts of drinking water and urine in volatile oil of A. lancea group and volatile oil of A. chinensis group increased， and the submandibular gland acini atrophied， the whole blood viscosity of rats in the volatile oil of A. lancea group increased significantly （P<0.01）， the expression levels of COX7A2 and SDHD mRNA， the activities of SDH， LDH and Na⁺-K⁺-ATPase increased significantly （P<0.01）， and the expression of AQP2 in kidney decreased significantly （P<0.01）. Compared with the normal group， the expression level of COX7A2 mRNA， SDH activity and whole blood viscosity in the volatile oil of A. chinensis group increased （P<0.05， P<0.01）， the AQP2 and SDH mRNA expression levels， LDH and Na⁺-K⁺-ATPase activities had no significant difference. The comprehensive score analysis of each index showed that the effect of volatile oil of A. lancea on dryness and energy metabolism was stronger than that of volatile oil of A. chinensis， and there was a positive correlation between dryness index and energy metabolism index. ConclusionThe two indexes show that medicinal properties of A. lancea is stronger than that of A. chinensis， and energy metabolism is closely related to the dryness of Atractylodis Rhizoma. It is suggested that it is reasonable to evaluate the dryness effect of Atractylodis Rhizoma from the perspective of energy metabolism， which can further enrich the evaluation indexes of medicinal properties.

The mean disease free interval is (39.96±27.58) months. The overall survival and disease free survival at 1, 2 and 5 years are 100%, 100% and 87%, respectively. Conclusions:Neuroendocrine carcinoma of the breast occurs more frequently in elderly women, often with large tumor size, low rate of regional lymph node and distant metastasis, moderate histological grade, early clinical stage, and the molecular typing is mostly Luminal A.The overall prognosis is fair.

【Objective】 To investigate the influence of different packaging methods on the volume of low-dose(0.5 U) suspended leucocyte depleted red blood cells(SLD RBC) and provide reference for accurate labeling. 【Methods】 Bags of SLD RBC in 1.5 U and 2 U were randomly sampled to measure the weight and specific gravity of each bag, so as to estimate the blood volume.The relationship between the weight and volume of 0.5 U blood, split from different parent bags, was analyzed and the linear regression equation was put forward.The regression equation was used to calculate and analyze the difference in the volume of 0.5 U SLD RBC prepared by three different packaging methods (A: manual multi-bag average packing; B: instrument multi-bag average packing; C: manual single-bag packing) in actual work. 【Results】 The specific gravity of 1.5 U (38 bags) and 2 U SLD RBC (39 bags) were (1.090±0.011) g/mL and (1.097±0.013) g/mL, respectively, and the difference was statistically significant (P<0.05). After the 0.5 U subsidiary bags were split from the parent bags(1.5 U or 2 U), the regression equations for the volume (Y) of 0.5 U and gross weight (X) of the whole bag were respectively: Y1.5 U packing=0.902 7X-12.52 (P<0.05) and Y2 U packing=0.905 6X-13.15(P<0.05). In actual blood packaging, the average blood volume of 0.5 U subsidiary bags split from 1.5 U bag, using method A and B, were smaller than those split from 2 U bag [(62.12±5.38) mL and (62.50±6.77) mL vs (67.72±3.81) mL and(68.39±6.44)mL] (P<0.05), with the deviation of low-dose blood volume from 5.593 mL to 5.887 mL.The volume deviation by method B (10.84% and 9.42%) were greater than that by method A (8.67% and 5.63%). The average volume of 0.5 U subsidiary bags split from 1.5 U and 2 U by method C were (65.49±1.72) mL and (64.99±1.91) mL (P>0.05), with volume deviation at 2.63% and 2.94%, respectively.The mean volume value of overall 0.5 U blood (n=483) was (65.35±5.34) mL. 【Conclusion】 For packaging 0.5 U subsidiary bags, the instrument multi-bag packaging showed the largest volume deviation, followed by the manual multi-bag packaging and the single-bag packaging.The volume labeling of low-dose SLD RBC should be established, according to the specifications of parent bags and specific gravity.

【Objective】 To retrospectively analyze the clinical use of low-dose blood components in Dongguan and the trend of clinical pediatric blood use, so as to provide reference for better preparation and inventory management of low-dose blood components in blood centers. 【Methods】 The clinical consumption of RBCs, platelets and plasma of Dongguan Blood Center from 2015 to 2020 was counted. The compositions and changes of low-dose blood components by specifications (0.25 U, 0.5 U), years and hospitals (public grade A general hospital, public grade A specialized hospital, private grade A hospital, private hospital equivalent to grade A, regional central hospital, public township hospital, small private hospital) were analyzed. 【Results】 The cumulative growth rates of low-dose RBCs, platelets, and plasma in 6 years were 10.78%, 1 098.55% and -29.41%, respectively, and the compound annual growth rates were 2.07%, 64.34% and -6.73%, respectively. The composition of low-dose blood components in RBCs, platelets and plasma was different (P<0.05) in different levels of hospitals, among which RBCs and plasma were the mostly used in public grade A specialized hospital, accounting for 45.08% (7 272 /16 133) and 53.18% (7 199/13 373) respectively, while platelets were the mostly used in private grade A management hospitals, accounting for 77.38% (3 393/4 385), dominated by apheresis platelets 53.84% (1 144/2 125) and irradiated apheresis platelets 99.51% (2 249/2 260). The composition ratios of 0.25 U and 0.5 U RBCs used in different hospitals were significantly different (P<0.05). The 0.25 U RBCs were used mostly in public grade A hospitals (62.60%, 3 502/5 594) and 0.5 U RBCs in public grade A specialized hospitals (62.09%, 6 544/10 539). 【Conclusion】 The total consumption of low-dose blood components in clinical pediatrics from 2015 to 2020 were as follows: platelets had increased significantly year by year, RBCs had increased steadily and with fluctuation, plasma had a downward trend year by year. The consumption volume and varieties used in different levels of hospitals were uneven, which may be related to the development of pediatrics departments in hospitals and their capabilities to conduct new business. Regular monitoring of the trend of low-dose blood component consumption is of great significance to guarantee the pediatric clinical blood supply.

Objective:To explore the effect of family integrated care (FIC) combined with intelligent health education platform in health education for elderly patients with stroke.Methods:Eighty patients with stroke were included from the Department of Neurology of the Second Affiliated Hospital of Chongqing Medical University from June 2019 to May 2020. They were divided into the experimental group and the control group ( n=40, respectively) by the random number table method. Patients in the control group received routine FIC in the Department of Neurology. Additional intelligent health education platform was provided for the experimental group to carry out intensive education. The modified Barthel index scale, self-care compliance scale and hospital anxiety and depression scale (HADS) were used before and after the intervention to evaluate patient′s self-care ability, self-care compliance and the degree of anxiety and depression.
