The purpose of this study was to systematically analyze the antidepressant mechanism of Chaigui granules from the perspective of biological metabolic network by using integrated metabolomics and biological network analysis tools. The model of chronic unpredictable mild stress (CUMS) depression rat was established, and LC-MS-based plasma metabolomics was used to identify the key metabolites and analyze metabolic pathways underlying the antidepressant effects of Chaigui Granules. The key metabolites regulated by Chaigui granules was integrated with biological network analysis tools to further focus on the key metabolic pathways and explore the potential targets of the antidepressant effect of Chaigui granules. The results showed that there were significant differences in the plasma levels of 20 metabolites in the model group compared with the control group (P < 0.05), Chaigui granules significantly regulated 12 metabolites including docosatrienoic acid, 3-hydroxybutyric acid, 4-hydroxybenzaldehyde, chenodeoxycholic acid, cholic acid, L-glutamine, glycocholic acid, linoleyl carnitine, L-tyrosine, N-acetylvaline, palmitoylcarnitine, arachidonic acid. Further network analysis of the key metabolites regulated by Chaigui granules indicated that plasma arachidonic acid metabolism might be the core pathway for the antidepressant effect of Chaigui granules, with 10 proteins were potential targets for the antidepressant effect of Chaigui granules, including CYP2B6, CYP2E1, CYP2C9, CYP2C8, PLA2G6, PTGS2, ALOX15B, PTGS1, ALOX12 and ALOX5. The animal experimental operations involved in this paper was followed the regulations of the Animal Ethics Committee of Shanxi University and passed the animal experimental ethical review (Approval No. SXULL2020028).

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Aim To explore the mechanism of Huoxue Rongluo reeipe in promoting angiogenesis after ischemic stroke based on the correlation between mir-370-3p and JAK2/STAT3 pathway.Methods Hats were randomly divided into six groups.MCAO/R method was used to establish the model.After seven days of intragastrie administration,the expressions of CD31 ,vWF and vascular endothelial growth factor ( VEGF) in brain tissue were observed by immunofluorescence stai- ning; the expression of JAK2 ,p-jak2,STAT3 and p- STAT3 in brain tissue was detected by Western blot; J the expressions of JAK2,STAT3 mRNA and mir-370- 3p in brain tissue were detected by real-time PCR f RT-PCR) ; the correlation between mir-370-3p and JAK2/STAT3 pathway was analyzed by Pearson correlation ; the expressions of lncma-hl9 and mir-370-3p were detected by real-time quantitative PCR ( RT qPCR) ; the targeting relationship between lncrna-hl9 and mir-370-3p was detected by luciferase reporter assay.Results Huoxue Rongluo decoction could increase the microvessel density and average fluorescence intensity of VEGF,up-regulate JAK2 and STAT3 mR- NA,down-regulate the expression of mir-37()-3p,and promote the expressions of JAK2,p-jak2 ,STAT3 and p- STAT3.Mir-370-3p was highly negatively correlated with JAK2 and STAT3 mRNA respectively,which could be reversed by stattic,an inhibitor of STAT3 SH2 domain.Conclusions Huoxue Rongluo recipe may stimulate angiogenesis after ischemic stroke by down- regulating the expression of mir-370-3p,activating JAK2 / STAT3 pathway and promoting the expression of downstream VEGF,so as to improve the symptoms of neurolo.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

Cerebral infarction is a clinical disease with corresponding neurological symptoms caused by cerebral ischemia and hypoxia caused by cerebral blood supply disorder. It is one of the most common cerebrovascular diseases and a serious threat to human health. The prevention and treatment of cerebral infarction has an important social significance. Angiogenesis is the key starting point for medical treatment of cerebral infarction, and signal transduction and transcriptional activators (STAT)/hypoxia inducing factor-1(HIF-1)/vascular endothelial growth factor (VEGF) pathway are important pathways to mediate angiogenesis after cerebral infarction. This paper took the angiogenesis as the starting point and the upstream molecules of STAT/HIF-1/VEGF signal pathway STAT3 and miRNA as the main study objects, and comprehensively discussed the results of chip sequencing, experimental research, traditional Chinese medicine (TCM) pathogenesis and TCM treatment. Based on the regulatory mode of "TF-miRNA" and the idea of "micro-whole", it is suggested that under the guidance of the basic theory of TCM, cubic compound prescriptions of TCM and its active components might activate the STAT/HIF-1/VEGF signal pathway through STAT3/miRNA feedback loop to promote angiogenesis after cerebral infarction, which puts forward a deep molecular mechanism and new direction for the treatment of cerebral infarction with TCM.

Ligusticum chuanxiong is a well-known traditional Chinese medicine plant. The study on its molecular markers development and germplasm resources is very important. In this study, we obtained 24 422 unigenes by assembling transcriptome sequencing reads of L. chuanxiong root. EST-SSR was detected and 4 073 SSR loci were identified. EST-SSR distribution and characteristic analysis results showed that the mono-nucleotide repeats were the main repeat types, accounting for 41.0%. In addition, the sequences containing SSR were functionally annotated in Gene Ontology (GO) and KEGG pathway and were assigned to 49 GO categories, 242 KEGG pathways, among them 2 201 sequences were annotated against Nr database. By validating 235 EST-SSRs,74 primer pairs were ultimately proved to have high quality amplification. Subsequently, genetic diversity analysis, UPGMA cluster analysis, PCoA analysis and population structure analysis of 34 L. chuanxiong germplasm resources were carried out with 74 primer pairs. In both UPGMA tree and PCoA results, L. chuanxiong resources were clustered into two groups, which are believed to be partial related to their geographical distribution. In this study, EST-SSRs in L. chuanxiong was firstly identified, and newly developed molecular markers would contribute significantly to further genetic diversity study, the purity detection, gene mapping, and molecular breeding.

BACKGROUNDBiliary cast syndrome (BCS) was a postoperative complication of orthotopic liver transplantation (OLT), and the reason for BSC was considered to relate with ischemic type biliary lesions. This study aimed to evaluate the relationship between BCS following OLT and the hepatic artery resistance index (HARI), and to observe pathological changes and morphology of biliary casts.

METHODSTotally, 18 patients were diagnosed with BCS by cholangiography following OLT using choledochoscope or endoscopic retrograde cholangiopancreatography. In addition, 36 patients who did not present with BCS in the corresponding period had detectable postoperative HARI on weeks 1, 2, 3 shown by color Doppler flow imaging. The compositions of biliary casts were analyzed by pathological examination and scanning electron microscopy.

RESULTSHARI values of the BCS group were significantly decreased as compared with the non-BCS group on postoperative weeks 2 and 3 (P < 0.05). Odds ratio (OR) analysis of HARI 1, HARI 2, HARI 3 following the operation was >1 (OR = 1.300; 1.223; and 1.889, respectively). The OR of HARI 3 was statistically significant (OR = 1.889; 95% confidence interval = 1.166-7.490; P = 0.024). The compositions of biliary casts were different when bile duct stones were present. Furthermore, vascular epithelial cells were found by pathological examination in biliary casts.

CONCLUSIONSHARI may possibly serve as an independent risk factor and early predictive factor of BCS. Components and formation of biliary casts and bile duct stones are different.

OBJECTIVETo analyze the epidemiological characteristics of pediatric burn in the midwest region of Inner Mongolia and the related areas, and to provide reference for seeking pertinent measures of prevention and treatment.

METHODSMedical records of patients hospitalized in the 253rd Hospital of PLA, the 322nd Hospital of PLA, and the Inner Mongolia Autonomous Region Hospital from January 1996 to December 2010 were collected. Patients were divided into pediatric burn group with specific reason (group SF, with scald resulted from construction defect of Guo-lian-kang--a heatable brick bed linked to a cooking pot), and burn control group with other causes (group C) according to the main injury cause. Clinical data of patients in both groups, including general condition, family background, occurrence regularity, and outcome, were analyzed. The epidemiological trend of variation before and after taking preventive measures (1996 to 2001 and 2002 to 2010) was compared. Data were processed with chi-square test and rank sum test.

RESULTS(1) General condition: out of 16 595 pediatric burn patients, 15 816 cases (95.3%) suffered scald due to liquids with high temperature, and 779 cases (4.7%) suffered burns due to other causes. Patients in group SF (scald due to specific cause--Guo-lian-kang) accounted for 32.2% (5089/15 816) of the total suffered scald by liquids with high temperature, and 30.7% (5089/16 595) of all the inpatients the cause of burn was related to Guo-lian-kang (group SF). The patients in group SF admitted to the 322nd Hospital of PLA accounted for 34.2% of all the inpatients admitted to this hospital (1803/5267), more than the other two hospitals in this study. The number of patients in group C was 11 506, accounted for 69.3% of all the inpatients. The age of patients ranged from 8 months to 5 years in group SF and 1 month to 12 years in group C. The age of the majority of patients ranged from 1 to 3 years in both groups. The ratio of male to female was 2.1:1.0 in group SF and 1.4:1.0 in group C. The incidence of scald involving multiple body parts in group SF (3590 cases accounting for 70.5%) was obviously higher than that of group C (6311 cases accounting for 54.8%, χ(2) = 361.138, P < 0.01). In both group SF and group C, the incidence in different sites was ranked from high to low as follows: upper limbs, lower limbs, the head-face-neck region, and the trunk. The degree of injury in group SF was much more severe than that of group C (Z = 27.770, P < 0.01). The rate of patients without pre-hospital treatment was 31.2% (1588/5089) in group SF, which was obviously higher than that of group C (24.8%, 2857/11 506, χ(2) = 73.010, P < 0.01). The rate of patients treated with cryotherapy was obviously lower in group SF (14.7%, 747/5089) than in group C (19.6%, 2255/11 506, χ(2) = 57.636, P < 0.01). The rate of patients treated with delayed resuscitation (6 hours after injury) in group SF (31.5%, 1601/5089) was obviously higher than that of group C (7.8%, 897/11 506, χ(2) = 1545.234, P < 0.01). (2) Family background and occurrence regularity: in group SF, 67.3% (3424/5089) of the patients came from farming area, 22.1% (1123/5089) from villages and towns, and 10.7% (542/5089) from urban areas. In group C, 32.4% (3727/11 506) of the patients came from farming area, 48.4% (5570/11 506) from villages and towns, and 19.2% (2209/11 506) from urban areas. Most of the patients in group SF (77.8%, 3958/5089) were injured between October and March, while most of the patients in group C (58.2%, 6697/11 506) were injured between May and October. (3) Outcome and epidemiological variation: the cure rate of patients in group SF was 32.3% (1645/5089), which was obviously lower than that of group C (44.7%, 5143/11 506, χ(2) = 215.615, P < 0.01). The mortality of patients in group SF was 1.6% (79/5089), and it was obviously higher than that of group C (0.4%, 46/11 506, χ(2) = 62.700, P < 0.01). From 1996 to 2001, patients in group SF accounted for 42.5% (2213/5212), while patients in group C accounted for 57.5% (2999/5212) of the inpatients scalded by hot liquid. After taking preventive measures against injury due to Guo-lian-kang, incidence of scald injury in group SF was lowered to 27.1% (2876/10 604), while the incidence in group C remained at 72.9% (7728/10 604) of the inpatients with hot liquid scald from 2002 to 2010. The difference between the two periods was statistically significant (χ(2) = 376.695,P < 0.01).

CONCLUSIONSThe defect of construction of Guo-lian-kang is one of the main factors that lead to a high incidence of pediatric burn in the midwest of Inner Mongolia. Installation of a protective bannister between the cooking pot and the "kang (heatable brick bed)" can obviously reduce the incidence of scald injury. Special injury-causing factors, unprofessional pre-hospital treatment of the wound, delayed resuscitation after shock are the main causes of increasing mortality and disability, and they constitute the key targets of prevention and treatment of such injury in future.
