Shengyutang is a famous classical formula of tonic， which is made from Siwutang with Ginseng Radix et Rhizoma and Astragali Radix. It is included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. Based on the Principles of Key Information Research of Ancient Famous Classical Formulas， this paper used bibliometrics to sort out and research the key information of Shengyutang in the aspects of history， composition， origin and processing， dosage， decocting method， efficacy and indications. After research， it has been found that this formula was first recorded in Lanshi Micang written by LI Dongyuan during the Jin dynasty， composed of Rehmanniae Radix， Rehmanniae Radix Praeparata， Chuanxiong Rhizoma， Ginseng Radix et Rhizoma， Astragali Radix and Angelicae Sinensis taproot. The name of the formula passed down through generations was relatively unified， with clear origins and veins. In later generations， this formula was the mainstream， and adjustments were made to the dosage and composition according to the indication. In the formula， Astragalus membranaceus var. mongholicus was selected as the origin of Astragali Radix， and the origins of other medicinal materials were consistent with the 2020 edition of Chinese Pharmacopoeia. Except for Rehmanniae Radix Praeparata， the other medicinal materials were made from raw products， and the dosage form was boiled powder. According to the measurement standard in the Jin dynasty， the recommended usage and dosage were 1.24 g of Rehmanniae Radix， Rehmanniae Radix Praeparata， Chuanxiong Rhizoma， Ginseng Radix et Rhizoma each， 2.07 g of Astragali Radix and Angelicae Sinensis taproot each， crushed into coarse particles that pass through the 4 mesh sieve but can't pass through the 10 mesh sieve， added 1 200 mL of water and boiled to 300 mL， and removed the residue. Shengyutang has the functions of tonifying Qi and blood， and blood intake， treating various sores， and restlessness and insomnia caused by excessive blood flow. In ancient times， this formula was widely used in the treatment of surgical sores， gynecological diseases， deficiency syndrome， etc. In modern clinical practice， it is mostly used to treat gynecological， neurological， musculoskeletal， hematological diseases caused by Qi and blood deficiency. In this paper， the key information of Shengyutang was researched by reviewing relevant ancient literature， in order to provide reference for the modern application and development of this formula.

OBJECTIVE: To compare the efficacy and safety of intravenous colistin sulfate combined with nebulized inhalation versus intravenous monotherapy for pulmonary infections caused by carbapenem-resistant organism (CRO). METHODS: A multicenter retrospective cohort study was conducted. Clinical data were collected from patients admitted to the intensive care unit (ICU) of 10 tertiary class-A hospitals in Henan Province between July 2021 and May 2023, who received colistin sulfate for CRO pulmonary infections. Data included baseline characteristics, inflammatory markers [white blood cell count (WBC), neutrophil count (NEU), procalcitonin (PCT), C-reactive protein (CRP)], renal function indicators [serum creatinine (SCr), blood urea nitrogen (BUN)], life support measures, anti-infection regimens, clinical efficacy, microbiological clearance rate, and prognostic outcomes. Patients were divided into two groups: intravenous group (colistin sulfate monotherapy via intravenous infusion) and combination group ((intravenous infusion combined with nebulized inhalation of colistin sulfate). Changes in parameters before and after treatment were analyzed. RESULTS: A total of 137 patients with CRO pulmonary infections were enrolled, including 89 in the intravenous group and 48 in the combination group. Baseline characteristics, life support measures, daily colistin dose, and combination regimens (most commonly colistin sulfate plus carbapenems in both groups) showed no significant differences between two groups. The combination group exhibited higher clinical efficacy [77.1% (37/48) vs. 59.6% (52/89)] and microbiological clearance rate [60.4% (29/48) vs. 39.3% (35/89)], both P < 0.05. Pre-treatment inflammatory and renal parameters showed no significant differences between two groups. Post-treatment, the combination group showed significantly lower WBC and CRP [WBC (×10⁹/L): 8.2±0.5 vs. 10.9±0.6, CRP (mg/L): 14.0 (5.7, 26.6) vs. 52.1 (24.4, 109.6), both P < 0.05], whereas NEU, PCT, SCr, and BUN levels showed no significant between two groups. ICU length of stay was shorter in the combination group [days: 16 (10, 25) vs. 21 (14, 29), P < 0.05], although mechanical ventilation duration and total hospitalization showed no significant differences between two groups. CONCLUSIONS Intravenous colistin sulfate combined with nebulized inhalation improved clinical efficacy and microbiological clearance in CRO pulmonary infections with an acceptable safety profile.

Objective To develop a military cross-cultural symptom scale(MCCSS)and evaluate its reliability and validity.Methods The dimensions and items of the scale were determined through literature analysis,questionnaire surveys,group discussions,expert consultations,and pre-experiments.Cluster sampling was employed to collect data from the participants to examine the psychometric properties of the scale.Results The MCCSS comprised 38 items across 9 factors:depression,anxiety,somatic symptoms,misanthropic tendency,sleep problems,compulsions,psychotic symptoms,stress trauma,and defensiveness.Item analysis revealed that the 37 items(except 1 forced-choice item)exhibited correlations from 0.538 to 0.875 with the total scale score(all P＜0.01),with critical ratios ranging from 5.190 to 28.149,indicating good discriminative power.The Cronbach's α coefficients for the total scale and subscales ranged from 0.825 to 0.972,and the Spearman-Brown split-half reliability coefficients ranged from 0.747 to 0.955.The results of confirmatory factor analysis showed that x2/df=3.419,standardized root mean square residual=0.033,root mean square error of approximation=0.073,normed fit index=0.868,incremental fit index=0.903,Tucker-Lewis index=0.887,comparative fit index=0.902,and the scale's first-order 9-factor model fit well.The loads of each item on the factor to which it belonged ranged from 0.597 to 0.954(all P＜0.01).The correlation coefficients between the scale and the scale for criterion-related validity ranged from 0.392 to 0.773(all P＜0.01),and the correlation coefficients between the scale and the scale for convergent validity ranged from 0.257 to 0.519(all P＜0.01).Conclusion The MCCSS in this study has good reliability and validity and can be used as a mental health testing and screening tool for military personnel.

Objective To investigate the factors influencing mood and sleep among special operation personnel,so as to provide evidence for the prevention and intervention of related issues.Methods A total of 600 special operation personnel during their special duty were enrolled by random sampling method.Basic information was collected by a general information questionnaire.Mood and sleep status were evaluated by self-rating anxiety scale(SAS),self-rating depression scale(SDS),and Pittsburgh sleep quality index scale(PSQI).Results Spearman correlation analysis showed that factors associated with anxiety were years of work experience(r=0.099,P=0.016),family residence(r=-0.153,P＜0.001),and sleep status(r=0.199,P＜0.001);the factors associated with depression were relationship with parents(r=-0.134,P=0.001),family residence(r=-0.144,P＜0.001),and sleep status(r=0.122,P=0.003);and the factors associated with sleep were age(r=0.088,P=0.031),years of work experience(r=0.079,P=0.049),and number of children(r=0.083,P=0.043).Binary logistic regression analysis showed that depression was not an influencing factor of sleep(odds ratio[OR]=1.302,95%confidence interval[95%CI]0.759-1.758,P=0.086),while anxiety was an influencing factor of sleep(OR=2.187,95%CI 1.608-4.695,P=0.001).Conclusion The sleep status of special operation personnel investigated in this survey is related to age and years of work experience,and is influenced by anxiety.Therefore,greater attention should be given to sleep issues in the occupational health support of special operations.Additionally,years of work experience,family residence,relationship with parents,and sleep status are related to anxiety and depression among special operation personnel.It is necessary to focus on the mental health of older workers and those with longer tenure.

AIM:To investigate the therapeutic effect of menstrual blood-derived endometrial stem cells(MenSCs)on chemotherapy-induced intestinal mucositis and flora disorders in mice,and to explore the potential mecha-nism.METHODS:The mice were randomly divided into 3 groups including normal treatment,cisplatin(Cis)treatment and Cis+MenSC treatment,with 10 mice in each group.To induce intestinal mucositis,the mice were treated with Cis(2 mg·kg-1·d-1)by intraperitoneal injection for 5 consecutive days.Control mice for normal group were received equal vol-umes of normal saline.For Cis+MenSC treatment,MenSCs(1×106)was transplanted into the mice of Cis treated mice through tail vein.The performances and weight changes of mice were examined during the experiment.After the treat-ment,the small intestine and colon were isolated for subsequent HE staining,the ratio of F4/80 and IL-6 positive cells in small intestine were detected by immunohistochemical staining,and the expression of tight junction,inflammation and apoptosis related proteins was detected by Western blot.16S rDNA amplicon sequencing was performed to detect the diver-sity and richness of intestinal flora in mice.RESULTS:Compared to the Cis group,the MenSCs-treated mice showed sig-nificantly increased body weight,relieved intestinal lymphocytes infiltration,alleviated intestinal villous edema,and or-derly arranged glands in intestinal tissues.Further analysis indicated that MenSCs transplantation significantly up-regulat-ed the expression of intestinal tight junction related proteins ZO-1 and occludin in Cis-treated mice(P＜0.05).Subse-quently,MenSCs transplantation significantly inhibited the macrophages infiltration in intestinal tissues(P＜0.01),down-regulated the expression of pro-inflammatory factors IL-1 and IL-6 and pro-apoptotic protein Bax(P＜0.01),while up-regu-lated anti-inflammatory factor IL-10 and anti-apoptotic protein Bcl-2(P＜0.01).Additionally,further microflora sequenc-ing indicated that MenSCs transplantation prevented mice from Cis-induced intestinal flora disorder,and significantly re-duced the abundance of harmful bacteria such as isenbergiella tayi and Anaerotruncus colihominis(P＜0.01).At the same time,the abundance of beneficial bacteria Lactobacillus apodemi was increased(P＜0.05),thereby restoring the composi-tion and function of healthy intestinal flora.CONCLUSION:MenSCs transplantation alleviates the chemotherapy-in-duced damage of intestinal structure,relieves the symptoms of chemotherapy-induced mucositis and restores the homeosta-sis of intestinal flora in mice.

Objective To explore the intervention mechanism of Changzhou Tongbian Formula on functional constipation(FC)combined with depression in rats.Methods A rat model of FC combined with depressive-like behaviors was established by using gastric gavage of berberine hydrochloride and chronic unpredictable mild stress.The model rats were randomly divided into blank group,model group,lactulose group,and Changzhou Tongbian Formula high-,medium-,and low-dose groups,and the intervention was carried out for five weeks.The fecal water content was calculated before and after intervention.The small intestinal propulsion rate was calculated after intervention.The depressive-like behavior levels of rats were evaluated by forced swimming test and sucrose preference test before and after intervention.The colonic mucosal morphology was observed by HE staining.The morphology and number of pyramidal cells in the hippocampal CA1 and DG regions were observed by Nissl staining.The relative protein expression levels of the transient receptor potential vanilloid 4(TRPV4)in colonic tissue,as well as brain-derived neurotrophic factor(BDNF),tyrosine kinase receptor B(TrkB),mitogen-activated protein kinase(MAPK),and cAMP-response element binding protein(CREB)in the hippocampus of rats in each group were detected by Western Blot method.Results Compared with the blank group,the fecal water content of rats in the model group was significantly reduced(P＜0.001),the small intestinal propulsion rate was significantly lower(P＜0.01),the sucrose preference index was significantly decreased(P＜0.001),the number of pyramidal cells in the CA1 and DG regions of the hippocampus was significantly reduced(P＜0.001),and the TRPV4 in the colon and the BDNF,TrkB,MAPK,and CREB protein contents in the hippocampus were all significantly decreased(all P＜0.001).Compared with the model group,the fecal water content of the Changzhou Tongbian Formula high-,midium-,low-dose groups and the lactulose group were significantly increased(P＜0.001,P＜0.01).The small intestinal propulsion rate of the Changzhou Tongbian Formula high-,low-dose groups and lactulose group were significantly increased(P＜0.01,P＜0.05).The sucrose preference indices of the Changzhou Tongbian Formula high-,midium-,low-dose groups and lactulose group were significantly increased(P＜0.01,P＜0.05).There was no abnormality in the colonic histology.The numbers of pyramidal cells in the CA1 and DG regions of the hippocampus of the Changzhou Tongbian Formula high-,midium-,low-dose groups and lactulose group were significantly increased(P＜0.01,P＜0.001).The TRPV4 content in the colon of the Changzhou Tongbian Formula high-,midium-,low-dose groups and lactulose group were significantly increased(P＜0.001),and the BDNF,TrkB,MAPK,and CREB protein contents in the hippocampus were all significantly increased(P＜0.05,P＜0.01,P＜0.001).Conclusion After intervention,Changzhou Tongbian Formula can significantly improve the TRPV4 content in the colon of model rats with the comorbidity of FC with depression,increase the moisture content of feces,promote intestinal peristalsis and improve constipation.Meanwhile,TRPV4 can activate the BDNF/TrkB/MAPK pathway,trigger an increase in downstream CREB,improve neuroplasticity and thus alleviate some depressive-like behavior.

Objective To investigate the mental health and influencing factors of naval officers and soldiers,and provide data support for formulating effective psychological intervention measures.Methods The 12-item general health questionnaire(GHQ-12)was used to conduct a sample survey among 5 336 naval officers and soldiers from October to November 2021.SPSS 26.0 software,chi-square test and regression analysis were used for descriptive statistics.Results A total of 5 102(95.61%)valid questionnaires were collected.The average GHQ-12 score was 0.55±1.18,and the proportion of high-risk individuals for mental health was 3.06%.Chi-square test showed that there were significant differences in the distribution of mental health status among interviewees with different ages,education levels,marriage status,family economy,family relationship,growing family,history of mental diseases among close relatives,major changes encountered during growth,hobbies and specialties,recent work pressure and recent interpersonal relationship(P≤0.001).Regression analysis showed that age(P=0.006),family relationship(P<0.001),family economy(P=0.010),major changes encountered during growth(P<0.001),recent work stress(P<0.001)and recent interpersonal relationship(P<0.001)were main influencing factors for mental health of naval officers and soldiers.Conclusion The mental health of naval officers and soldiers was generally good,but some individuals still have mental health problems,which are affected by many factors.It is necessary to pay more attention to the mental health problems caused by their age,education,family,growth experience,stress and interpersonal relationship.

Drug-associated reward memories are conducive to intense craving and often trigger relapse. Simvastatin has been shown to regulate lipids that are involved in memory formation but its influence on other cognitive processes is elusive. Here, we used a mass spectrometry-based lipidomic method to evaluate the impact of simvastatin on the mouse brain in a cocaine-induced reinstatement paradigm. We found that simvastatin blocked the reinstatement of cocaine-induced conditioned place preference (CPP) without affecting CPP acquisition. Specifically, only simvastatin administered during extinction prevented cocaine-primed reinstatement. Global lipidome analysis showed that the nucleus accumbens was the region with the greatest degree of change caused by simvastatin. The metabolism of fatty-acids, phospholipids, and triacylglycerol was profoundly affected. Simvastatin reversed most of the effects on phospholipids induced by cocaine. The correlation matrix showed that cocaine and simvastatin significantly reshaped the lipid metabolic pathways in specific brain regions. Furthermore, simvastatin almost reversed all changes in the fatty acyl profile and unsaturation caused by cocaine. In summary, pre-extinction treatment with simvastatin facilitates cocaine extinction and prevents cocaine relapse with brain lipidome remodeling.

Objective: To establish a nude mouse model of subcutaneous lung cancer using dual fluorescence reporting genes of luciferase (Luc) and near-infrared fluorescent protein (iRFP). Methods: The Luc and iRFP expressed lentiviral vector was constructed by Gateway method. After verified by sequencing, the lentivirus particle was prepared and infected into lung cancer A549 cells. Successfully infected A549 (mA549) cells were selected by puromycin and amplified. The expression of Luc and iRFP were observed under fluorescence microscope, and the expression of c-Met protein on the cell surface was detected by immunofluorescence. Twelve female nude mice were randomly divided into 2 groups, 6 in each group. A549 and mA549 cells were inoculated subcutaneously into the right forelimb of nude mice. The growth and fluorescence expression of the tumor were observed by in vivo imaging. The tumor formation was evaluated by hematoxylin-eosin (HE) staining and immunohistochemistry. Results: The Luc and iRFP stably expressed mA549 cell line was successfully constructed. The expressions of iRFP and Luc in mA549 cells were observed under fluorescence microscope. The results of immunofluorescence showed that c-Met protein expressed in both A549 cells and mA549 cells. The growth period of mA549 xenograft in nude mice was moderate and the tumorigenesis rate was 100%. The growth trend of mA549 cells in vivo was not significantly different from that of A549 cells (P>0.05). HE staining and immunohistochemistry results showed that the tumor issues displayed typical histopathological features of tumor. Immunohistochemistry results showed that both A549 and mA549 tumors expressed c-Met protein. Conclusion A stable, real-time monitoring model of iRFP-Luc-A549 lung cancer cell xenograft in nude mice was successfully constructed.
