RESUMEN
With the high prevalence of diabetes, its long-term treatment, and many complications, there is a need for a new diabetes self-management model in developing countries. Therefore, this study aimed to assess the implementation and effect of a new diabetes self-management model, known as the healthcare cloud information platform, in Shanghai, China. The implementation of the new model was evaluated in terms of the equipment coverage in community health service centres and the services provided. The effect was assessed according to the treatment rate and control rate from 2012 to 2017. Their correlations with the self-management rate were analysed using Spearman's test. It was found that the Shanghai healthcare cloud information platform had covered a total of 237 community health service centres in all of the 16 administrative districts, equipping them with 2489 health stations, by 2017. An average of 8966 people uploaded data to the healthcare cloud information platform every day, with the accumulated service up to 12 043 508 person-times and an average daily increase of 13 227.9. The treatment rate of diabetes patients in Shanghai increased from 42.9% in 2012 to 78.0% in 2017, and the control rate increased to 72% in 2017, compared with 63% in 2012. Furthermore, there was a significant correlation between the treatment rate, control rate, and self-management rate. The findings indicate that it is feasible to implement the new healthcare cloud information platform for diabetes self-management and that it is effective.

Duloxetine intermediate (S)-(-)-3-N-methylamino-1-(2-thienyl)-1-propanol was synthesized using ACA liquid-core immobilized Saccharomyces cerevisiae CGMCC No. 2230. The optimum culture time for ACA liquid-core immobilized cells was found to be 28 h. The optimum ACA liquid-core capsule formation conditions were found to be 90% chitosan deacetylation, 30,000-50,000 chitosan molecular weight, 5.0 g/L chitosan, and pH 6.0 citrate buffer solution. The highest activity was found when reduction conditions were pH 6.0, 30 °C and 180 rpm. The ACA-immobilized cells can be reused nine times and only 40% of the activity is retained after nine cycles. Product inhibition of reduction was observed in batch reduction. Continuous reduction in the membrane reactor was found to remove the product inhibition on reduction and improve production capacity. Conversion reached 100% and enantiometric excess of (S)-(-)-3-N-methylamino-1-(2-thienyl)-1-propanol exceeded 99.0% in continuous reduction of 5 g/L 3-N-methylamino-1-(2-thienyl)-1-propanone in the membrane reactor.

BACKGROUND: Renal fibrosis is the most common pathway leading to end-stage renal disease. It is characterized by excess extracellular matrix (ECM) accumulation and renal tissue damage, subsequently leading to kidney failure. Asperulosidic acid (ASPA), a bioactive iridoid glycoside, exerts anti-tumor, anti-oxidant, and anti-inflammatory activities, but its effects on renal fibrosis induced by unilateral ureteral obstruction (UUO) have not yet been investigated. PURPOSE: This study aimed to investigate the protective effect of ASPA on renal fibrosis induced by UUO, and to explore its pharmacological mechanism. METHODS: Thirty-six Sprague-Dawley (SD) rats were randomly divided into six groups: sham group, UUO model group, three ASPA treatment groups (10, 20, and 40â¯mg/kg), and captopril group (20â¯mg/kg). Rats were administered vehicle, ASPA or captopril intraperitoneally once a day for 14 consecutive days. Urea nitrogen (BUN), uric acid (UA) and inflammatory factors in serum samples were evaluated on the 7th, 10th, and 14th day after renal fibrosis induction. In addition, the 12â¯h urine was collected to test the content of urinary protein (upro) on the 14th day. The obstructive renal tissues were collected for pathological analysis (hematoxylin and eosion (H&E) staining and Masson's Trichrome staining) and immunohistochemical analysis on the 14th day after renal fibrosis induction. The mRNA expression of related factors and the protein levels of smad2, smad3, and smad4 were measured in UUO-induced rats by real time PCR and Western blot, respectively. RESULTS: The levels of BUN, UA, and upro were elevated in UUO-induced rats, but ASPA treatment improved renal function by reducing the levels of BUN, UA, and upro. The protein levels of tumor necrosis factor-α (TNF-α), interleukin-1ß (IL-1ß) and IL-6, as well as the mRNA levels of TNF-α, IL-1ß, IL-6, monocyte chemoattractant protein-1 (MCP-1) and interferon-γ (IFN-γ), were decreased after ASPA administration (10, 20 and 40â¯mg/kg) in a dose-dependent manner. The ASPA exerted an alleviation effect on the inflammatory response through inhibition of nuclear factor-kappa B (NF-κB) pathway. In addition, reductions in α-smooth muscle actin (α-SMA), collagen III, and fibronectin expression were observed after ASPA administration at doses of 20 and 40â¯mg/kg. Furthermore, the renal expression of transforming growth factor-ß1 (TGF-ß1), smad2, smad3, and smad4 was down-regulated by ASPA treatment at doses of 20 and 40â¯mg/kg. CONCLUSION: ASPA possessed protective effects on renal interstitial fibrosis in UUO-induced rats. These effects may be through inhibition of the activation of NF-κB and TGF-ß1/smad2/smad3 signaling pathways.

To raise the training quality, the development of their own capacity is crucial, but community medical institutions also need close cooperation with the departments of general practice in medical schools and the higher-level general hospitals. This article discusses the integration model of management, teaching and research in general practice talent training based on the cooperation of community teaching bases with relevant governmental departments, professional societies/associations, general hospitals and medical schools.
RESUMEN
BackgroundCompared with male adolescents, depression among female adolescents is of higher prevalence and greater severity. The level of generalized trust correlates with the severity of depression, and attachment correlates with the level of generalized trust. Therefore, based on the mediating role of generalized trust between attachment and depression, this study explores the pathogenesis of depression in female adolescents. ObjectiveTo explore the mediating role of generalized trust between paternal, maternal and peer attachment and depression in female adolescents, so as to provide references for improving the depression of female adolescents. MethodsThis study included 73 female adolescents who met the diagnostic criteria for depressive disorder in the International Classification of Diseases, tenth edition(ICD-10) as well as received outpatient and inpatient treatment in Hangzhou Seventh People's Hospital between March 2022 and October 2022. Investigation was conducted by use of Revised Inventory of Parent and Peer Attachment (IPPA-R), the Inclusive General Trust Scale (IGTS) and Children's Depression Inventory (CDI). Pearson correlation analysis was used to explore the correlation between each scale score. The Bootstrap method was used to test the mediating role of generalized trust between attachment and depression. Results① CDI score in female adolescents with depression was negatively correlated with scores of paternal, maternal and peer attachment in IPPA-R (r=-0.463, -0.459, -0.447, P<0.01). Scores of paternal, maternal and peer attachment in IPPA-R were positively correlated with IGTS score (r=0.372, 0.318, 0.395, P<0.01). IGTS score was negatively correlated with CDI score (r=-0.531, P<0.01 ). ②The test of mediating role showed that the direct effect of paternal, maternal and peer attachment on depression level was significant in female adolescents with depression (effect size=-0.138, -0.136, -0.107, 95% CI: -0.236~-0.039, -0.242~-0.029, -0.203~-0.012). ③The mediating role of generalized trust between paternal, maternal peer attachment and depression level was significant (effect size=-0.069, -0.066, -0.071, 95% CI: -0.127~-0.021, -0.137~-0.010, -0.145~-0.018). ConclusionPaternal, maternal and peer attachment can influence the depression level of female adolescents both directly and indirectly through the generalized trust.

Objective:To investigate the effect of online acceptance and commitment therapy(ACT) group intervention on psychological flexibility of undergraduate students with facial negative physical self.Methods:From March to June 2022, thirty-two undergraduates with facial negative physical self-image were recruited, assessed and selected from a university in Zhejiang Province.The subjects were randomly divided into the training group( n=16) and the control group( n=16). The training group received 20 days of online ACT group intervention, while the control group kept waiting.The cognitive fusion questionnaire(CFQ), acceptance and action questionnaire version Ⅱ(AAQ-Ⅱ) and negative physical self scale-face(NPSS-F) were used to measure the two groups before and after intervention and 1 month after intervention.Repeated measurement analysis of variance(ANOVA) conducted was used to compare scale results with SPSS 26.0. Results:(1)The interaction effect between group and time of CFQ scores was statistically significant( F(1.625, 48.755)=4.316, P=0.025, ηp2=0.126). After intervention, the CFQ score of the training group was significantly lower than those of the control group(34.38±8.66, 40.94±8.82, P<0.05). The CFQ scores of the training group after intervention and 1 month after intervention(36.00±9.49) were both significantly lower than those before intervention(41.87±8.72, all P<0.05). (2)The interaction effect between group and time of AAQ-Ⅱ scores was marginally statistically significant( F(2, 29)=3.009, P=0.065, ηp2=0.172). After intervention, the AAQ-Ⅱ score of the training group was significantly lower than those of the control group(24.12±4.97, 28.69±6.78, P<0.05). The AAQ-Ⅱ score of the training group after intervention was significantly lower than those before intervention(28.75±6.11, P<0.05). (3)The interaction effect between group and time of NPSS-F scores was not statistically significant( F(2, 29)=1.509, P=0.238, ηp2=0.094), while the main effect of time was marginally statistically significant between the two groups( F(2, 29)=3.315, P=0.051, ηp2=0.186). The NPSS-F score of the training group after intervention was significantly lower than those before intervention(16.06±6.67, 18.81±7.85, P<0.05). Conclusion:Online ACT group intervention can effectively reduce the cognitive fusion and experiential avoidance of undergraduate students with facial negative physical self, then can improve their psychological flexibility.

RESUMEN
Hepatosteatosis is characterized by abnormal accumulation of triglycerides(TG),leading to prolonged and chronic inflammatory infiltration.To date,there is still a lack of effective and economical therapies for hepatosteatosis.Oridonin(ORI)is a major bioactive component extracted from the traditional Chinese medicinal herb Rabdosia rubescens.In this paper,we showed that ORI exerted significant protective ef-fects against hepatic steatosis,inflammation and fibrosis,which was dependent on LXRα signaling.It is reported that LXRα regulated lipid homeostasis between triglyceride(TG)and phosphatidylethanol-amine(PE)by promoting ATCL and EPT1 expression.Therefore,we implemented the lipidomic strategy and luciferase reporter assay to verify that ORI contributed to the homeostasis of lipids via the regulation of the ATGL gene associated with TG hydrolysis and the EPT1 gene related to PE synthesis in a LXRα-dependent manner,and the results showed the TG reduction and PE elevation.In detail,hepatic TG overload and lipotoxicity were reversed after ORI treatment by modulating the ATCL and EPT1 genes,respectively.Taken together,the data provide mechanistic insights to explain the bioactivity of ORI in attenuating TG accumulation and cytotoxicity and introduce exciting opportunities for developing novel natural activators of the LXRα-ATGL/EPT1 axis for pharmacologically treating hepatosteatosis and metabolic disorders.

RESUMEN
Multidrug resistance of tumors has been a severe obstacle to the success of cancer chemotherapy. The study wants to investigate the reversal effects of imperatorin (IMP) on doxorubicin (DOX) resistance in K562/DOX leukemia cells, A2780/Taxol cells and in NOD/SCID mice, to explore the possible molecular mechanisms. K562/ DOX and A2780/Taxol cells were treated with various concentrations of DOX and Taol with or without different concentrations of IMP, respectively. K562/DOX xenograft model was used to assess anti-tumor effect of IMP combined with DOX. MTT assay, Rhodamine 123 efflux assay, RT-PCR, and Western blot analysis were determined in vivo and in vitro. Results showed that IMP significantly enhanced the cytotoxicity of DOX and Taxol toward corresponding resistance cells. In vivo results illustrated both the tumor volume and tumor weight were significantly decreased after 2-week treatment with IMP combined with DOX compared to the DOX alone group. Western blotting and RT-PCR analyses indicated that IMP downregulated the expression of P-gp in K562/DOX xenograft tumors in NOD/SCID mice. We also evaluated glycolysis and glutamine metabolism in K562/DOX cells by measuring glucose consumption and lactate production. The results revealed that IMP could significantly reduce the glucose consumption and lactate production of K562/DOX cells. Furthermore, IMP could also remarkably repress the glutamine consumption, α-KG and ATP production of K562/DOX cells. Thus, IMP may sensitize K562/DOX cells to DOX and enhance the antitumor effect of DOX in K562/DOX xenograft tumors in NOD/SCID mice. IMP may be an adjuvant therapy to mitigate the multidrug resistance in leukemia chemotherapy.
RESUMEN
Objective: Constructing and validating a nomogram model for preoperative prediction of intrahepatic cholangiocarcinoma (ICC) lymph node metastasis to assist decision making during surgery. Methods: Retrospectively collecting the clinical and pathological data of 1 031 ICC patients who underwent partial hepatectomy at Eastern Hepatobiliary Surgery Hospital of Naval Military Medical University,General Hospital of Eastern Theater Command,or Zhongda Hospital Southeast University from January 2003 to January 2014. There were 682 males and 349 females; mean age was 54.7 years(range:18 to 82 years). There were 562 patients who underwent lymph node dissection and 469 patients who did not. Among the patients in the dissection group,Lasso regression method was used to filtrate preoperative variables related to lymph node metastasis and establish a nomogram. Bootstrap method was used to internally validate the discrimination of the nomogram,and the accuracy of the nomogram was assessed by using calibration curves. Patients were divided into low-moderate and high-risk groups based on model prediction probability. Propensity score matching(PSM) was used to analyze the overall survival (OS) and recurrence-free survival (RFS) of patients with and without lymph node dissection in the two groups,and to judge the importance of lymph node dissection in the two groups. Results: Six factors related to ICC lymph node metastasis were determined by Lasso regression,including hepatitis B surface antigen,CA19-9,age,lymphadenopathy,carcinoembryo antigen and maximum tumor diameter. These factors were integrated into a nomogram to predict ICC lymph node metastasis. The aera under curve value was 0.764,and the C-index was 0.754. Stratified analysis showed that OS and RFS in the high-risk group of lymph node metastasis were significantly lower than those in the low-medium risk group(median OS:14.6 months vs. 27.0 months,P<0.01; median RFS:9.1 months vs. 15.5 months,P<0.01). In the high-risk group,the median OS was 16.7 months and 6.3 months(Log-rank test: P=0.187;Wilcoxon test:P=0.046),and the median RFS was 11.0 months and 4.8 months(P=0.403),respectively in the lymph node dissection group and undissected group after PSM. In the low-medium-risk group,the median OS was 22.7 months and 26.7 months(P=0.288),and the median RFS was 13.0 months and 14.5 months(P=0.306),respectively in the lymph node dissection group and undissected group after PSM. Conclusions: The nomogram could be used for preoperative prediction of lymph node metastasis and prognostic stratification in patients with ICC. For patients with high risk of lymph node metastasis predicted by the model,active dissection should be performed. For patients predicted to be at low-moderate risk,lymph node dissection might be optional in some specific cases.

OBJECTIVE: To improve the detection and control of infectious diseases in Guangxi, China. SETTING/PARTICIPANTS: Guangxi province in southwest China has almost 50 million people, of whom approximately 30% reside in urban and 70% in rural areas. There are 12 minority nationality groups living in the region. INTERVENTION: A village doctor reports any infectious disease outbreak to the Reporting Network, which notifies the Service Network to organize the clinical response. This is supported by the Government Network that coordinates the response among the multiple layers of local governments. OUTCOMES: Since 2002 when the Three Networks system was first started, the time from incidence to report has been shortened on average from 30.6 to 7.6 days and the number of cases has increased from slightly less than 5000 cases/year (4965) to almost 10,000 cases/year (9873). Average mortality has decreased from 3.23% to 0.74%. The Three Networks system has been successful in controlling measles outbreaks; and during SARS, when 11 cases came to Guangxi from the neighbouring Guangdong province, there were only 11 additional new cases with no community spread and no spread to medical staff. CONCLUSION: The Three Networks system has played an important role in infectious disease prevention and control in Guangxi province, and may be applicable to other areas with a similar situation.

Morels (Morchella spp.) are valuable medicinal and edible mushrooms. In this study, chemical profiles of aromas and lipophilic extracts of black morel (Morchella importuna) grown in China were analyzed by gas chromatography/mass spectroscopy, along with the evaluation of antioxidant and antimicrobial activities for the lipophilic extracts. Sixty-five compounds in total were identified from the aromas, and 1-octen-3-ol was the main component for aromas of fresh (34.40%) and freeze-dried (68.61%) black morels, while the most abundant compound for the aroma of the oven-dried sample was 2(5H)-furanone (13.95%). From the lipophilic extracts, 29 compounds were identified with linoleic acid as the main compound for fresh (77.37%) and freeze-dried (56.46%) black morels and steroids (92.41%) as the main constituent for an oven-dried sample. All three lipophilic extracts showed moderate antioxidant activities against 2,2-diphenyl-1-picrylhydrazyl and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) with the IC50 values ranging 7.56 ∼ 17.52 mg/mL and 5.75 ∼ 9.73 mg/mL, respectively, and no obvious antimicrobial activity was observed for lipophilic extracts. The drying methods affect the chemical profile of black morel, and freeze-drying was favorable for retaining nutrients and morel smell. This is the first report on the aroma and lipophilic extracts of M. importuna grown in China.

Using the protein encoded by hub gene as receptor and tanshinone Ⅱ A as ligand ,the molecular docking was carried out with AutoDock 1.5.6 tool. RESULTS :A total of 38 active components of S. miltiorrhiza with high gastrointestinal absorption and their corresponding 72 targets,755 PAA-related target genes were identified. Results of Venn diagram showed that there were 33 intersecting targets of active components of chuqi90@163.com S. miltiorrhiza with PAA. Tanshinone ⅡA,dihydrotanshinolac- tone and other components may be important nodes of the target network related to active component-PAA. FOS,APP,ACHE, CASP3 and PTGS2 may be the hub genes in PPI network of intersecting targets. Results of GO enrichment showed that the intersecting targets were mainly concentrated in adrenergic receptor activity ,catecholamine binding ,G protein-coupled amine receptor activity and so on ;KEGG pathway enrichment analysis showed that the intersecting targets were mainly enriched in neuroactive ligand-receptor interaction ,cGMP-PKG signaling pathway ,endocrine resistance ,EGFR-tyrosine kinase inhibitor resistance and calcium signaling pathway.Molecular docking analysis showed that tanshinone ⅡA could form hydrogen bonds with many amino acid residues such as VAL- 580 of proto oncogenes c-Fos ,amyloid precursor protein ,acetylcholinesterase,caspase 3 and prostaglandin G/H synthase 2. CONCLUSIONS :The active components of S. miltiorrhiza play a role in the treatment of PAA by directly or indirectly acting on neuroactive ligand-receptor interaction ,cGMP-PKG signaling pathway ,endocrine resistance , EGFR-tyrosine kinase inhibitor resistance resistance and calcium signaling pathway.
RESUMEN
Liver, as a critical organ of metabolism and detoxification, can be damaged by viral infection, drug abuse, and heavy drinking. Liver diseases pose a serious threat to people's health and life in China.At present, drug therapy has been primarily adopted clinically in the treatment of the liver injury.In-depth investigation of the mechanism of liver-protective drugs is of great significance to the prevention and treatment of clinical liver diseases.In recent years, with the development of the medical industry in China, an increasing number of studies have focused on the treatment of liver injury with Chinese medicine.Compared with western medicine, Chinese medicine is advantageous in few side effects and overall regulation, which plays a pivotal role in liver protection.However, its underlying mechanism in liver protection still needs to be further studied due to its complex compositions and diverse targets.Metabolomics, a new approach to studying the metabolic pathway of biological systems, provides integral and systematic views in the investigation of liver protection with Chinese medicine. By virtue of metabolomics, the mechanism of Chinese medicine in multi-target and multi-pathway liver protection can be analyzed comprehensively, and the corresponding biomarkers can also be screened out. The authors analyzed the studies of the treatment of chemical liver injury models induced by carbon tetrachloride (CCl4), dimethylnitrosamine (DMN), α-naphthyl isothiocyanate (ANIT), and alcohol by Chinese medicinal compounds, single herbal medicines, and monomers of Chinese medicine based on metabolomics, and summarized the biomarkers and related metabolic pathways of Chinese medicine in the intervention of each type of liver injury, aiming at providing a reference for the further research and clinical application in the treatment of different types of liver injuries by Chinese medicine.
