Objective: To evaluate the intervention efficacy of integrated group social skills training on social ability in school age patients with high functioning ASD, so as to provide a reference for improving social skills in children with high functioning ASD. Methods: From January 2021 to December 2023, 62 children aged 7-12 with high functioning ASD who visited the Children s Psychiatry Outpatient Department of the Affiliated Kangning Hospital of Ningbo University were recruited, and were randomly divided into a training ( n =31) and a control group ( n =31) by a random number table method. The training group received a 20 week structured group social training program (mental interpretation courses and social courses), while the control group received only conventional treatment. Chinese version of Griffith Empathy Measure Parent Ratings (GEM-PR) and Social Response Scale (SRS) were used to assess the symptoms of social deficits before and after treatment. Emotional face recognition tasks and eye movement trajectories were used to test the characteristics of social visual attention in children with ASD. Group comparison was conducted using t-test and Mann-Whitney U test. Results: At baseline, there were no significant differences in GEM-PR score ( t = -1.20 to -0.81), SRS score ( t =-0.36-1.75), emotional face recognition accuracy and reaction time ( t =-0.58-1.85), and eye movement trajectory ( U/t =-1.63-0.29) between the two group ( P >0.05). After intervention, the total GEM-PR score and empathic cognitive factor score of training group [18.00(10.00，24.00)，9.00(8.00，13.00)] were significantly higher than those of the control group [12.00(-1.00，18.00)，2.00(-2.00，7.00)], and the total SRS score and social cognition, social perception, social communication, social motivation (73.23±14.20, 16.16±2.72, 6.58±2.50, 24.29±5.61, 9.52±3.73) were significantly lower than those of the control group (95.26±15.29, 19.90±2.84, 12.58±2.49,31.94±6.38, 13.74±4.81) ( U/t =-2.38, -4.59; -5.88, -5.29, -9.47, -5.01, -3.87, P <0.05). The overall correct rate of emotional face recognition and the correct rate of angry, fearful and neutral faces recognition in the training group [(81.55±6.62)%，(76.86±12.06)%，(79.61±12.42)%，(94.27±6.26)%] were significantly higher than the control group [(70.55±13.82)%，(62.82±18.77)%，(67.18±18.85)%，(79.60±20.05)%], and the average reaction time [(2 226.70±274.43)ms] was lower than the control group [(2 417.27±324.10)ms] (t=4.00, 3.50, 3.07, 3.89, -2.42, P<0.05). The time to first eye gaze [764.74 (748.64, 793.73) ms] in the training group was significantly lower than that in the control group [810.92 (782.86, 877.42) ms], and the proportion of moderatetohigh intensity attention area in the face [(37.37±1.27)%] was significantly higher than that in the control group [(30.34±1.23)%] (U/t=3.44, 8.89, P<0.05). Conclusion Integrated group social training can significantly improve the social communication and empathy ability of high functioning ASD children, increase active attention and recognition ability of faces, and improve mental development of children with ASD.

Objective To investigate the epidemiology of elderly respiratory tract infection (RTI) cases in a hospital in Xuzhou region from 2020 to 2022. Methods The cases of RTI patients in a hospital were screened from May 2020 to December 2022, and 548 cases that met the criteria were included in the study. Patient case data were analyzed for symptoms, pathogen distribution, and differences in patient distribution under different screening conditions (age, disease, and season). Results More than 90.00% of the included RTI patients presented with symptoms of cough, sputum, wet rales and pleural effusion was less common. The top three comorbidities were cardiovascular disease (153 patients, 27.92%), cerebrovascular disease (133 patients, 24.27%), and gastrointestinal disease (105 patients, 19.16%).All 548 elderly patients tested positive for respiratory pathogens (100.00%). There were 540 cases of single pathogen infection (98.54%) and 8 cases of mixed infection (1.46%). The top five single pathogen infections were Pseudomonas aeruginosa (92 cases, 16.76%), Escherichia coli (78 cases, 14.21%), drug-resistant Staphylococcus aureus (69 cases, 12.57%), Klebsiella pneumoniae (65 cases, 11.84%), and Mycoplasma pneumoniae (46 cases, 8.38%). The highest detection rate of respiratory pathogens was found in patients >90 years old, whose main pathogens were Pseudomonas aeruginosa, Klebsiella pneumoniae and drug-resistant Staphylococcus aureus. The next highest rates of pathogen detection were found in patients aged 86-91 and 81-85 years, unlike patients >90 years, who had a higher rate of Escherichia coli detection. Unlike other age groups, patients <75 years old had a higher percentage of influenza B virus detection. The highest incidence of pneumonia was found in 45.62% (250 cases). Escherichia coli had the highest detection rate in acute bronchitis/episodes and pneumonia, respiratory syncytial virus had the highest detection rate in wheezing bronchitis, Klebsiella pneumoniae had the highest detection rate in bronchopneumonia, and Pseudomonas aeruginosa had the highest detection rate in fever. The highest detection rate of pathogens was found in fall (36.50%), followed by spring (27.01%). The distribution of pathogen infections in all seasons was matched with the results of pathogenicity testing. Streptococcus oxysporus had the highest number of infections in the fall (χ²=20.33, P<0.001). Conclusion Elderly respiratory tract infections in this region are most common in patients over 90 years old, with the highest incidence of pneumonia and high incidence in fall, and the pathogens are mainly Pseudomonas aeruginosa, Escherichia coli and drug-resistant Staphylococcus aureus. Attention to distinguish the above characteristics can provide some support for early diagnosis and treatment of respiratory infections in the elderly in this region.

[Objective] To investigate the protective effect of Salvia miltiorrhiza injection (SMI) on the kidneys of HBOC-CHP01 resuscitated haemorrhagic shock rats. [Methods] A 50% haemorrhagic shock rat model was established, with 12 rats divided into two groups: SMI + HBOC-CHP01 group and HBOC-CHP01 group, with 6 rats in each group. The rats in the SMI+ HBOC-CHP01 group were given an equal volume of HBOC-CHP01 for resuscitation after haemorrhagic shock, and an 8 mL/kg dose of SMI. Rats in the HBOC-CHP01 group were resuscitated by administering an equilibrium blood loss volume of HBOC-CHP01 and given an 8 mL/kg dose of 0.9% NaCl solution. Blood was taken from rats at five points: before bloodletting (baseline), during haemorrhagic shock (HS), immediately after resuscitation (RS0h), 1 h after resuscitation (RS1h), and 24 h after resuscitation (RS24h). A blood gas analyser was used to detect the lactate level (Lac), glucose content (Glu), residual base (BEecf), pH, bicarbonate (HCO3-), high iron haemoglobin (MetHb). White blood cells (WBC), platelets (PLT), haemoglobin content (Hb), carboxyhaemoglobin (COHb) were detected using a quintuple classification. Blood creatinine (SCr), uric acid (UA), kidney-related indexes were detected using biochemistry instrument. Kidney tissues of the rats were taken after 24 h of resuscitation and after execution, and the inflammation of kidneys of the rats of the two groups was analyzed using HE staining. Fluorescence staining was used to detect the level of ROS in the kidneys of rats in both groups. [Results] At RS 0h, the Beecf, Glu and Lac levels of rats in the SMI+HBOC-CHP01 group were significantly lower than those of rats in the HBOC-CHP01 group, and the pH level of rats in the SMI+HBOC-CHP01 group was significantly higher than that of rats in the HBOC-CHP01 group, and the Glu levels of rats in the SMI+HBOC-CHP01 group were significantly lower than those of rats in the HBOC-CHP01 group at RS 1h. At RS 0h, the WBC, PLT and COHb contents of rats in the SMI+HBOC-CHP01 group were all significantly higher than those of rats in the HBOC-CHP01 group, and at RS 1h, the WBC content of rats in the SMI+HBOC-CHP01 group was significantly higher than that of rats in the HBOC-CHP01 group; at RS 1h, the UA content of rats in the SMI+HBOC-CHP01 group was significantly lower than that of rats in the HBOC-CHP01 group; at RS 24h, the SCr content of rats in the SMI+HBOC-CHP01 group was significantly lower than that of rats in the HBOC-CHP01 group; at RS 24h, the inflammation level of kidney tissues of rats in the SMI+HBOC-CHP01 group was significantly lower than that of rats in the HBOC -CHP01 group rats, and the ROS and MPO levels in the kidney tissues of rats in the SMI+HBOC-CHP01 group were significantly lower than those of rats in the HBOC-CHP01 group. [Conclusion] The combination of Salvia miltiorrhiza injection during the resuscitation of rats with severe haemorrhagic shock by HBOC-CHP01 can alleviate renal injury by reducing inflammatory response and oxidative stress.

[Objective] To extract hemoglobin (Hb) from red blood cells using osmotic pressure swelling method, expected to achieve a hemoglobin dissolution rate of ≥80% and a cell membrane integrity rate of ≥70%. [Methods] Human umbilical cord blood red blood cells were used as raw materials and phosphate buffer solution was used as the swelling solution for red blood cells. A three factor three-level orthogonal experiment (n=3) was conducted to determine the optimal matching conditions for selecting the osmolality molar concentration of phosphate buffer solution, pH value of hypotonic phosphate buffer solution and volume ratio of hypotonic phosphate buffer solution to washed red blood cells. Red blood cell swelling solution samples (n=6) were prepared by the optimal matching conditions and the original process conditions. The hemoglobin dissolution rate and cell membrane integrity rate were checked. In the expanded comparative experiment, red blood cell swelling solution samples (n=6) were prepared by the optimal matching conditions and the original process conditions, which was filtered by ultrafiltration membranes. The filtration time and hemoglobin yield were checked. [Results] The optimal matching conditions for preparing red blood cell swelling solution were obtained through orthogonal experiment as follows: osmotic pressure molar concentration was 30 mOsmol/Kg, pH was 7.8, and phosphate buffer to red blood cell volume ratio was 6∶1. On the basis of the above conditions, the red blood cell swelling solution sample was compared with the original process sample: the hemoglobin dissolution rate was (82.4±1.8)% vs (78.6±3.0)% (P<0.05), and the cell membrane integrity rate was (65.8±4.0)% vs (28.7±2.3)% (P<0.05). In the expanded comparative experiment, the optimal matching conditions were compared with the original process conditions: filtration time(s) (327±9) vs (434±13) (P<0.05), and hemoglobin yield was (72.3±1.2)% vs (66.0±1.4)% (P<0.05). [Conclusion] Compared with the original preparation process, the hemoglobin extraction process which optimized through orthogonal experiments greatly reduces the cell membrane fragmentation rate and minimizes the entry of cell membrane matrix into the target solution, ensuring a slightly higher hemoglobin dissolution rate, and reducing the preparation difficulty for the subsequent cell membrane separation and further purification.

MethodsA randomized， double-blind， placebo-controlled trial was conducted. A total of 72 patients with stable bronchiectasis with airflow limitation of phlegm-heat obstructing the lung and lung-spleen qi deficiency syndrome were randomly divided into treatment group and control group， with 36 cases in each group. On the basis of regular inhalation of tiotropium bromide inhalation spray， the treatment group was given Sufei Pingchuan Formula granules， and the control group was given Sufei Pingchuan Formula granule simulant. The course of treatment in both groups was 12 weeks. The pulmonary function of both groups before and after treatment was observed， specifically focusing on forced expiratory volume in one second （FEV1）； the modified British Medical Research Council （mMRC） dyspnea scale， 24-hour sputum volume， COPD assessment test （CAT）， and traditional Chinese medicine （TCM） syndrome scores were assessed before treatment and after 4， 8， and 12 weeks of treatment； acute exacerbations were recorded at weeks 4， 8， and 12； additionally， changes in routine blood tests， urinalysis， liver and kidney function， and adverse events were monitored before and after treatment. ResultsAfter treatment， 4 patients in the treatment group and 6 in the control group dropped out. After 12 weeks of treatment， FEV1 increased in both groups compared to pre-treatment levels （P＜0.05）， but the difference between groups was not statistically significant （P＞0.05）. Compared to before treatment， the treatment group showed a reduction in mMRC scores after 12 weeks （P＜0.05） and a decrease in 24-hour sputum volume， CAT scores， and TCM syndrome scores at weeks 4， 8， and 12 （P＜0.05）. In the control group， 24-hour sputum volume decreased after 12 weeks （P＜0.05）， and TCM syndrome scores decreased at weeks 8 and 12 （P＜0.05）. Compared to the control group， the treatment group showed a greater reduction in mMRC scores at week 12 （P＜0.05）， a decrease in 24-hour sputum volume and TCM syndrome scores at weeks 4， 8， and 12 （P＜0.05）， and lower CAT scores at weeks 8 and 12 （P＜0.05）. The frequency and number of acute exacerbations in the treatment group were significantly lower than those in the control group at week 12 （P＜0.05）. No severe adverse events occurred in either group. ConclusionSufei Pingchuan Formula can improve the pulmonary function FEV1， the severity of dyspnea， reduce 24-hour sputum volume and frequent acute exacerbations， and improve the quality of life in patients with bronchiectasis and airflow limitation， with good safety.

Zinc oxide nanoparticles(ZnO NPs)have been gradually introduced into people's lives due to their excellent properties.In daily contact,ZnO NPs can enter the human body in a variety of ways and accumulate in tissues and organs.Inhalation is an important means by which ZnO NPs enter the human body and deposit in lungs.Studies have shown that exposure of lungs to ZnO NPs will cause a range of negative effects.The mechanism of pulmonary toxicity induced by ZnO NPs is related to Zn2+release,oxidative stress,DNA damage,autophagy,inflammation and pulmonary surfactant dysfunction.This paper reviews the pulmonary toxicity and mechanisms of ZnO NPs,and summarizes the prevention and treatment strategies,which provides scientific basis for safer use of nanomaterials,and potential intervention strategies for the prevention and treatment of nanotoxicity.

Objective To study the cellular senescence and molecular mechanism of olaparib in MCF-7 breast cancer cells.Methods The effects of olaparib on the proliferation and migration of MCF-7 cells were detected dynamically by real-time cell analysis(RTCA)technology.The effects of olaparib on the Senescence was detected by using the senescence-associated β-galactosidase(SA-β-gal).Quantitative polymerase chain reaction was used to analyze the effects of olaparib on the expression levels of genes encoding the senescence-associated factors p16,p21,C/EBP homologous protein,interleukin(IL)-6,IL-8,plasminogen activator inhibitor 1,phosphatase and tensin homolog deleted on chromosome 10,p27,retinoblastoma gene,Ki67,and E2F1.The effects of olaparib on the expression levels of the senescence-associated proteins p21,γH2AX,pRB,cyclin D1,insulin-like growth factor binding protein 3,and Ki67 were analyzed by Western Blot.Results Olaparib inhibited the proliferation and migration and induced the senescence of MCF-7 cells.Long-term(96 h)treatment with olaparib significantly up-regulated the gene expression levels of p16,p21,p27,C/EBP homologous protein,IL-6,IL-8,plasminogen activator inhibitor 1,phosphatase and tensin homolog deleted on chromosome 10,and retinoblastoma protein(P＜0.01)and significantly down-regulated the gene expression levels of Ki67 and E2F1(P＜0.01)in MCF-7 cells.Olaparib significantly increased protein expression levels of p21,γH2AX,and insulin-like growth factor binding protein 3 in MCF-7 cells(P＜0.01,P＜0.01,P＜0.05)and significantly decreased cyclin D1,pRB,and Ki67 levels(P＜0.05,P＜0.01,P＜0.05).Conclusions Olaparib can inhibit proliferation and migration and induce senescence in MCF-7 breast cancer cells.

Background: MicroRNA (miRNA) plays a crucial role in neuropathic pain (NP) by targeting mRNAs. This study aims to analyze the regulatory function and mechanism of miR-382-5p/dual specificity phosphatase-1 (DUSP1) axis in NP. Methods: We utilized rats with chronic constriction injury (CCI) of the sciatic nerve as the NP model. The levels of miR-382-5p and DUSP1 were reduced by intrathecal injection of lentiviral interference vectors targeting miR-382-5p and DUSP1. The mRNA levels of miR-382-5p and DUSP1 in the dorsal root ganglions (DRGs) were measured by RT-qPCR assay. The pain behavior was evaluated by mechanical nociceptive sensitivity and thermal nociceptive sensitivity. The expression levels of interleukin-6 (IL)-6, IL-1β, and tumor necrosis factor-α in the DRGs were analyzed by ELISA assay. The targeting relationship between miR-382-5p and DUSP1 was verified by DLR assay and RIP assay. Results: Compared to the Sham group, the CCI rats exhibited higher levels of miR-382-5p and lower levels of DUSP1. Overexpression of miR-382-5p significantly decreased DUSP1 levels. Reducing miR-382-5p levels can lower the mechanical nociceptive sensitivity and thermal nociceptive sensitivity of CCI rats and inhibit the over-activation of pro-inflammatory factors. Reduced miR-382-5p levels decreased NP in CCI rats. DUSP1 is the target of miR-382-5p, and down-regulation of DUSP1 reverses the inhibitory effect of reduced miR-382-5p levels on NP. Conclusions Down-regulation of miR-382-5p inhibits the over-activation of pro-inflammatory factors by targeting and regulating the expression of DUPS1, thereby alleviating NP.

Objective To explore the effect and possible mechanism of berberine on the macro-phage polarization of human myeloid leukemia monocytic cell line THP-1 induced by oxidized low-density lipoprotein(ox-LDL).Methods THP-1 cells were induced into macrophages by PMA,and then according to different concentrations of berberine,the cells were divided into con-trol group,and 5,10,20,40 and 50 μmol/L berberine groups.After intervention for 24 or 48 h,CCK8 assay was used to detect cell viability for optimal concentration and time of berberine treat-ment.PMA-induced THP-1 macrophages were assigned into blank group,model group(ox-LDL),berberine group,inhibitor group(phosphatidyl inositol 3-kinase(PI3K)inhibitor LY294002)and berberine+inhibitor group(berberine+LY294002).The contents of inducible nitric oxide syn-thase(iNOS)and TGF-β1 were detected by ELISA.qPCR was employed to measure the mRNA expression of TNF-α,arginase 1(Arg1),PI3K and protein kinase B Akt1,and Western blotting was applied to detect the protein levels of Akt1 and phosphorylated protein kinase B antibody(p-Akt1).Results In 24 h after intervention,the macrophage activity was significantly lower in the 40 and 50 μmol/L berberine groups than the control group(P＜0.05),and after 48 h,the ac-tivity in all the 5 doses of berberine groups was obviously lower than that in the control group[(0.89±0.02)％,(0.82±0.03)％,(0.71±0.02)％,(0.62±0.03)％and(0.53±0.02)％vs(1.01±0.01)％,P＜0.05].Berberine treatment of 20 μmol/L for 24 h had little effect on cell viability,and the dose and the time were regarded as the best concentration and time.Compared with the blank group,iNOS content and TNF-α mRNA level were increased in the model group,while TGF-β1 content,mRNA levels of Arg1,PI3K and Akt1,and p-Akt1/Akt1 protein levels were de-creased(P＜0.05).iNOS content and TNF-α mRNA level were decreased,while TGF-β1 content,mRNA levels of Arg1,PI3K and Akt1 and protein levels of p-Akt1/Akt1s were increased in the berberine group than the model group(P＜0.05).Compared with the berberine group,iNOS con-tent and TNF-α mRNA level were increased,while mRNA levels of Arg1,PI3K and Akt1 and protein levels of p-Akt1/Akt1 were decreased in the berberine+inhibitor group(P＜0.05).Con-clusion Berberine can inhibit the inflammatory response of THP-1 macrophages induced by ox-LDL by activating PI3K/Akt1 pathway,and inhibit the M1 polarization and promote the M2 polarization of macrophages.
