Objective: To investigate the implementation and evaluate the effectiveness of health management services for patients with type 2 diabetes mellitus (T2DM) in Urumqi City from 2017 to 2021, so as to provide the reference for enhancing T2DM patients management. Methods: Data on the rates of record establishment, health management and standardized management for T2DM patients, and blood glucose control rate in managed patients in Urumqi City from 2017 to 2021 were collected through the quarterly reports on basic public health service management from the Weining Health Platform System. The trends in the four management indicators, and the differences between urban and rural areas were analyzed. Results: The rates of record establishment, health management and blood glucose control rate in managed patients in Urumqi City were 46.94%, 38.37% and 59.92%, respectively, showing upward trends from 2017 to 2021 (all P<0.05). The rate of standardized management was 75.89%, showing a downward trend (P<0.05). The rate of record establishment was higher in urban areas than in rural areas (47.76% vs. 40.56%, P<0.05). The rates of standardized management and blood glucose control in managed patients were lower in urban areas than in rural areas (75.18% vs. 81.46%, 58.93% vs. 67.64%, both P<0.05). The rate of health management was 38.39% in urban areas and 38.24% in rural areas, with no statistically significant difference (P>0.05). The trends in the rates of record establishment, health management and standardized management in both urban and rural areas were consistent with those in the overall population. Conclusions From 2017 to 2021, the rates of record establishment, health management and blood glucose control in managed patients in Urumqi City showed upward trends, while the rate of standardized management exhibited a downward trend. There were urban-rural differences in the rates of record establishment, standardized management and blood glucose control in managed patients.

Objective To explore the effect of community pharmacy outpatient service on patients with type 2 diabetes mellitus. Methods A non-randomized controlled study was conducted, and type 2 diabetes patients managed in the community were divided into an intervention group of 112 cases and a control group of 110 cases. The control group received routine medication guidance during general practice outpatient visits, while the intervention group received comprehensive pharmacy outpatient service intervention based on routine medication guidance in general practice. Follow-up visits were conducted every 3 months. Repeated measurement analysis of variance and multivariate linear regression analysis were used to evaluate the intervention effect of the pharmacy outpatient service. Results Fasting blood glucose and glycosylated hemoglobin levels in the intervention group showed a decreasing trend with the increase of intervention time compared to pre-intervention time （P<0.01）, with increased duration of weekly exercise, decreased staple food intake, increased vegetable intake, and increased medication adherence score （P<0.01）. After adjusting for confounding factors through multivariate linear regression model, pharmacy outpatient intervention was found to be an independent protective factor for fasting blood glucose level （β=−0.891, P<0.01） and glycosylated hemoglobin level （β=−0.760, P<0.01） in the study subjects. Conclusion The community pharmacy outpatient service could enhance the self-management ability of patients with type 2 diabetes mellitus, and effectively improve patients’ fasting blood glucose and glycosylated hemoglobin.

Objective To investigate the effect of electroacupuncture preconditioning on microglia polarization in rats after cerebral ischemia reperfusion(IR)injury and explore the role of tyrosine kinase 2(J AK2)/signal transducer and activator of transcription 3(STAT3)pathway in the process.Methods Forty-five clean-grade healthy male Sprague-Dawley rats were randomly and equally divided into sham operation group,IR group and electroacupuncture preconditioning group.Rat model of IR injury was induced with thread occlusion of the internal carotid artery.Before modeling,electroacupuncture preconditioning was applied to Baihui acupoint for 5 consec-utive days in the preconditioning group,and exposure of the cervical blood vessels were inflicted in the sham-operation group.At 24 h after reperfusion,the severity of neurological deficit was observed by modified neurological deficit score(mNSS),and the cerebral infarct volume was observed by TTC staining.Western blotting was used to detect the protein levels of classical acti-vated type(M1)marker inducible nitric oxide synthase(iNOS),alternative activated type(M2)marker arginase 1(Arg-1),JAK2 and p-JAK2,and STAT3 and p-STAT3,and q-PCR was applied to detect the mRNA expression of iNOS and Arg-1.The expression of TNF-α and IL-10 was measured by ELISA.Results Compared with the sham operation group,the mNSS,infarct vol-ume,protein levels of p-JAK2/JAK2,p-STAT3/STAT3,protein and mRNA levels of iNOS and Arg-1,and expression of TNF-α and IL-10 were significantly increased in the IR and electroacu-puncture preconditioning groups(P＜0.01).The preconditioning group had obviously lower mNSS,smaller infarct volume,decreased protein levels of p-JAK2/JAK2,p-STAT3/STAT3,re-duced protein and mRNA levels of iNOS,and declined TNF-α expression,but elevated expression of Arg-1 at protein(2.0±0.2 vs 1.5±0.1)and mRNA(4.2±0.8 vs 3.1±0.3)levels and increased IL-10 expression(49.1±7.1 pg/mg vs 27.9±5.9 pg/mg)when compared with the IR group(P＜0.01).Conclusion Electroacupuncture preconditioning can promote the polarization of microglia to M2 and inhibit the polarization of microglia to M1 after cerebral IR injury,which may be relat-ed to the inhibition of JAK2/STAT3 pathway.

Objective To investigate the impact of LncRNA FOXP4-AS1 regulating the EZH2/LATS2 axis on the proliferation and migration of bladder urothelial carcinoma(BUC)cells.Methods The Cancer Genome Atlas(TCGA)database and real-time quantitative PCR were utilized to analyze the expression of FOXP4-AS1 and LATS2 mRNA in BUC tissues.Cell proliferation was observed using MTT experiments,and migration was checked using Transwell assays.Western blot assays were performed to determine the expression of LATS2 and H3K27me3 proteins.RNA immunoprecipitation(RIP)and chromatin immunoprecipitation(ChIP)assays were employed to verify the relationship between FOXP4-AS1,EZH2 and LATS2.Results Compared with normal bladder tissues,FOXP4-AS1 expression was increased in tumor tissues,while LATS2 mRNA expression was decreased(P<0.01).Moreover,FOXP4-AS1 expression was elevated in EJ,T24,BIU-87,and 5637 cell lines compared to SV-HUC-1(P<0.01).The inhibition of FOXP4-AS1 resulted in a significant decrease in the proliferation,migration,and expression of H3K27me3 protein in BUC cells,while concurrently upregulating the expression of LATS2 mRNA and protein.Conversely,the overexpression of FOXP4-AS1 yielded contrasting effects(P<0.05).RIP and ChIP assays revealed that FOXP4-AS1 could recruit EZH2 to the promoter region of LATS2,leading to an enrich-ment of H3K27me3 in this region.Interference with LATS2 or EZH2 expression partially reversed the effects of FOXP4-AS1 silencing or overexpression on the proliferation and migration of BUC cells,with concomitant effects on LATS2 expression.Conclusion FOXP4-AS1 demonstrates a notable increase in expression in BUC,leading to a suppression of LATS2 expression through the recruitment of EZH2 to the promoter region of LATS2.This regula-tory process ultimately influences the proliferation and migration of BUC cells.

Objective:To measure the overall and lobulated volume of the liver with different degrees of liver fibrosis and to further observe pathological changes such as liver microvasculature, hepatocyte apoptosis, and regeneration in order to understand the macroscopic volume changes of the liver during liver fibrosis and its relationship with liver tissue microscopic pathology in patients with chronic liver disease.Methods:53 patients with chronic hepatitis B, alcoholic fatty liver disease, autoimmune liver disease, nonalcoholic fatty liver disease, and drug-induced chronic liver disease who underwent both liver biopsy tissue and abdominal magnetic resonance imaging were collected. Patients were divided into early (F1-2), middle (F3-4), and late (F5-6) in accordance with the Ishak fibrosis stage and Masson stain. The liver and spleen volumes were measured using ITK-SNAP software. CD31 immunohistochemical staining was used to reflect intrahepatic angiogenesis. Ki67 and HNF-4α multiplex immunohistochemical staining were used to reflect hepatocyte regeneration. GS staining was used to determine parenchymal extinction lesions. TUNEL staining was used to observe hepatocyte apoptosis. Spearman correlation analysis was used to analyze the relationship between liver volume changes and liver histopathological changes.Results:As liver fibrosis progressed, the total liver volume and right lobe liver volume gradually decreased ( P<0.05), while the spleen volume gradually increased ( P<0.05). The expression of CD31 and GS gradually increased ( P<0.05), and the expression of Ki67 first increased and then decreased ( P<0.05). The positivity rate of CD31 was negatively correlated with the right lobe liver volume ( r=-0.609, P<0.001) and the total liver volume ( r=-0.363, P=0.017). The positivity rate of Ki67 was positively correlated with the right lobe liver volume ( r=0.423, P=0.018), while the positivity rate of apoptotic cells was significantly negatively correlated with the total liver volume ( r=-0.860, P<0.001). The positivity rate of GS was negatively correlated with the right lobe liver volume ( r=-0.440, P=0.002), and the number of PELs was negatively correlated with RV ( r=-0.476, P=0.013). The CD31 positive staining area was negatively correlated with the Ki67 positive staining area( r=-0.511, P=0.009). Conclusion:As liver fibrosis progresses, patients with chronic liver disease have a depletion in total liver volume and right lobe liver volume, and this is mainly in correlation with fewer liver cells and liver tissue microvasculature disorders.

Objective:To explore the impact of artificial intelligence compressed sensing technology (CS-AI) on image quality in three-dimensional proton density weighted imaging (3D PDWI) of the unilateral hip joint.Methods:High-resolution unilateral hip imaging was conducted on 67 healthy volunteers at West China Hospital of Sichuan University from January to July 2023. Imaging was performed by using CS-AI 3D PDWI sequence with acceleration factors (AF) of 4, 6, 8, and 10, respectively. According to the AF, all subjects were divided into 4 groups: CS-AI 4, CS-AI 6, CS-AI 8 and CS-AI 10, with CS-AI 4 serving as a reference. Recording the scan time, the signal and noise intensity of the femoral head, muscle, and subcutaneous fat were measured by a senior radiologist and the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were then calculated. Additionally, two observers provided ratings for overall image quality and artifacts in the 4 groups, and statistical analysis was performed using the Friedman rank-sum test.Results:The acquisition times for CS-AI 4, CS-AI 6, CS-AI 8, and CS-AI 10 were 5 min 49 s, 3 min 54 s, 2 min 56 s and 2 min 22 s, respectively. Compared to CS-AI 4, the scanning time for CS-AI 6, CS-AI 8, CS-AI 10 were reduced by 32.95%, 50.14%, 59.31%, respectively. The objective evaluation revealed that the SNR and CNR of the femoral head and muscle in groups CS-AI 6, CS-AI 8, and CS-AI 10 were slightly lower than those in group CS-AI 4 ( P<0.05), and the differences were statistically significant. However, no statistically significant differences were found among the 3 groups ( P>0.05). The subjective evaluation indicated that the overall image quality scores of group CS-AI 8 [3 (3,4)] did not significantly differ from those of group CS-AI 4 and CS-AI 6( P>0.05); The mean scores of group CS-AI 4 and CS-AI 6 were 4 (4, 4); Scores of group CS-AI 10 was 3(3, 3), which statistically significant differ from those of the other groups ( P<0.05). The artifacts rating for groups CS-AI 4, CS-AI 6, CS-AI 8 and CS-AI 10 were 4 (4, 4), 4 (4, 4), 3 (3, 4), and 2 (2, 3) respectively. When AF was set to 10, the images exhibited the most severe artifacts ( P<0.05). For other AF values, artifact ratings did not differ significantly ( P>0.05). Conclusion:The CS-AI 3D-PDWI sequence with acceleration factor 8 can acquire high-resolution images of the unilateral hip joint that meet clinical diagnostic requirements while reducing scanning time.

Objective:To evaluate the relationship between glutathione S-transferase μ1 (GSTM1) and the apoptosis signal-regulating kinase 1 (ASK1)-c-Jun N-terminal kinase (JNK)/p38 mitogen-activated protein kinase (MAPK) signaling pathway during therapeutic hypothermia-induced reduction of cerebral ischemia-reperfusion injury (CIRI) in rats.Methods:One hundred clean-grade healthy male Sprague-Dawley rats, aged 8 weeks, weighing 260-280 g, were divided into 5 groups ( n=20 each) using a random number table method: sham operation group (S group), cerebral ischemia-reperfusion group (I/R group), therapeutic hypothermia group (H group), GSTM1 inhibitor+ therapeutic hypothermia group (IH group), and GSTM1 inhibitor + ASK1 inhibitor + therapeutic hypothermia group (IAH group). CIRI model was developed by occlusion of the left middle cerebral artery for 2 h, followed by restoration of the blood flow. A nylon thread was inserted into the internal carotid artery and advanced cephalad until resistance was met. The brain temperature was maintained at 36-37 ℃ during surgery. In H group, the head and neck were wiped with 75% alcohol immediately after reperfusion, and the brain temperature was maintained at 32-33℃ for 3 h, and the rest procedures were the same as those previously described in I/R group. In IH group, GSTM1 inhibitor itaconic acid 8.6 mg/kg was intraperitoneally injected at 24 and 1 h before developing the model, and the rest procedures were the same as those previously described in H group. In IAH group, ASK1 inhibitor selonsertib 10 mg/kg was given orally once a day for 4 consecutive days starting from 4 days before developing the model, and the rest procedures were the same as those previously described in IH group. Modified Neurological Severity Score (mNSS) was assessed at 24 h of reperfusion, then the rats were sacrificed and brains were harvested for microscopic examination of brain infarction, neuronal morphology (using HE staining) and for determination of the expression of GSTM1, ASK1, phosphorylated ASK1 (p-ASK1), JNK, phosphorylated JNK (p-JNK), p-38 MAPK and phosphorylated p-38 MAPK (p-p38 MAPK) (by Western blot) and neuronal apoptosis (by TUNEL assay). The percentage of the infarct size was calculated using TTC staining. The apoptosis rate was calculated. Results:Compared with S group, the mNSS, apoptosis rate of neurons, percentage of the cerebral infarct size, p-ASK1/ASK1 ratio, p-JNK/JNK ratio and p-p38 MAPK/p38 MAPK ratio were significantly increased, and the expression of GSTM1 was down-regulated in I/R group ( P<0.05). Compared with I/R group and IH group, the mNSS, apoptosis rate of neurons, percentage of the cerebral infarct size, p-ASK1/ASK1 ratio, p-JNK/JNK ratio and p-p38 MAPK/p38 MAPK ratio were significantly decreased, the expression of GSTM1 was up-regulated ( P<0.05), and the neuronal injury was significantly attenuated in H group. Compared with IH group, the mNSS, apoptosis rate of neurons, percentage of the cerebral infarct size, p-ASK1/ASK1 ratio, p-JNK/JNK ratio and p-p38 MAPK/p38 MAPK ratio were significantly decreased ( P<0.05), no significant change was found in GSTM1 expression ( P>0.05), and the neuronal damage was significantly attenuated in IAH group. Conclusions:The mechanism by which therapeutic hypothermia alleviates CIRI is related to up-regulating the expression of GSTM1 and inhibiting the activation of the ASK1-JNK-p38 MAPK signaling pathway in rats.

Objective:To evaluate the effect of selective cerebral mild hypothermia on the expression of histone deacetylase 1-3 (HDAC1-3) during focal cerebral ischemia-reperfusion (I/R) in rats.Methods:Sixty clean-grade healthy male Sprague-Dawley rats, aged 6-8 weeks, weighing 240-260 g, were divided into 4 groups ( n=15 each) using a random number table method: sham operation group (S group), focal cerebral I/R group (I/R group), selective cerebral mild hypothermia group (SCH group), and normothermia group (N group). Only the cervical vessels were isolated in S group. In the other three groups, sutures were inserted into the internal carotid artery to block the middle cerebral artery for 2 h, and then the sutures were pulled out to restore perfusion for 24 h. A focal cerebral I/R model was prepared. Normal saline at 20 ℃ and 37 ℃ was infused into the internal carotid artery at a rate of 0.6 ml/min for 10 min starting from the time point immediately after removal of the sutures in SCH group and N group respectively. Cerebral temperature and rectal temperature were continuously monitored during the operation. The modified neurological severity score (mNSS) was assessed at 24 h of reperfusion. The rats were then sacrificed under deep anesthesia and brains were obtained for determination of cerebral infarct size (by TTC staining). The tissues of the cerebral ischemic penumbra were taken for determination of the apoptosis rate of neurons (by TUNEL method) and lactylation modification and expression of HDAC1-3 (by Western blot) and for observation of the morphology of neurons (by HE staining). Results:Compared with S group, the mNSS, cerebral infarct size and apoptosis rate of neurons were significantly increased, HDAC1-3 expression was down-regulated, and the lactylation modification was increased in the other three groups ( P<0.05). Compared with I/R and N groups, the mNSS, cerebral infarct size and apoptosis rate of neurons were significantly decreased, HDAC1-3 expression was up-regulated, and the lactylation modification was decreased in SCH group ( P<0.05). There was no statistically significant difference in the aforementioned parameters between I/R group and N group ( P>0.05). HE staining showed that the morphology of neurons was intact and well-defined in S group, a large number of cells with edema and irregularly solidified nuclei were found in I/R group and N group, and the nuclear shrinkage and morphological changes of neurons were alleviated in SCH group. Conclusions:The mechanism by which selective cerebral mild hypothermia alleviates cerebral I/R injury may be related to up-regulation of HDAC1-3 expression in rats.

Objective:To evaluate the effects of remimazolam on gastrointestinal motor function in the patients undergoing gastrointestinal endoscopy.Methods:A total of 262 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 18-64 yr, with body mass index of 18-28 kg/m 2, scheduled for elective gastrointestinal endoscopy from May 2022 to August 2022, were divided into 2 groups ( n=131 each) using a random number table method: remimazolam group (group R) and propofol group (group P). The patients in group R received intravenous remimazolam 0.20-0.25 mg/kg, and patients in group P received intravenous propofol 1.5-2.0 mg/kg. The gastrointestinal endoscopy was performed when the patients′ Modified Observer′s Assessment of Alertness/Sedation scores ≤3. During fasting before gastrointestinal preparation, before gastrointestinal endoscopy and while leaving the post-anesthesia care unit (PACU), the concentrations of serum motilin and gastrin were measured by enzyme-linked immunosorbent assay, the intestinal peristalsis rating assessed by the endoscopist during the examination was recorded, the occurrence of hypotension and hypoxemia during the examination and occurrence of abdominal distension, abdominal pain, and nausea and vomiting during stay in PACU were recorded. Results:Compared with group P, the intestinal peristalsis rating was significantly increased, the serum motilin and gastrin concentrations were increased while leaving PACU, the incidence of hypotension and hypoxemia was decreased during the examination, and the incidence of abdominal distention was decreased during stay in PACU in group R ( P<0.05). Conclusions:Remimazolam has a milder inhibitory effect on secretion of gastrointestinal hormones than propofol in the patients undergoing gastrointestinal endoscopy and is helpful for the recovery of gastrointestinal motility.

Objective:To evaluate the role of Sirtuin 1/nuclear factor κB (SIRT1/NF-κB) signaling pathway in mild hypothermia-induced promotion of microglial polarization during oxygen-glucose deprivation and restoration (OGD/R).Methods:The well-grown BV2 microglia were divided into 4 groups ( n=36 each) using the random number table method: control group (group C), OGD/R group (group O), mild hypothermia group (group M), and mild hypothermia+ SIRT1 specific inhibitor EX527 group (group ME). Cells in group C were commonly cultured without any treatment. Cells in group O were subjected to 3 h of OGD followed by 21 h of restoration of O 2-glucose supply at 37 ℃. Cells in group M were subjected to 3 h of OGD followed by 21 h of restoration of O 2-glucose supply at 33 ℃.
