Objective:To explore the value of serum procalcitonin (PCT) and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score on predicting prognosis of elderly patients with sepsis.Methods:A retrospective cohort study, patients with sepsis who admitted to the department of emergency and the department of geriatric medicine of Peking University Third Hospital from March 2020 to June 2021 were enrolled. Patients' demographics, routine laboratory examinations, APACHE Ⅱ score that within 24 hours of admission were obtained from their electronic medical records. The prognosis during the hospitalization and one year after discharge were collected, retrospectively. Univariate and multivariate analysis of prognostic factors were performed. And Kaplan-Meier survival curves were used to examine overall survival.Results:A total of 116 elderly patients met inclusion criteria, 55 were alive and 61 were died. On univariate analysis, clinical variables such as lactic acid [Lac, hazard ratio ( HR) = 1.16, 95% confidence interval (95% CI) was 1.07-1.26, P < 0.001], PCT ( HR = 1.02, 95% CI was 1.01-1.04, P < 0.001), alanine aminotransferase (ALT, HR = 1.00, 95% CI was 1.00-1.00, P = 0.143), aspartate aminotransferase (AST, HR = 1.00, 95% CI was 1.00-1.01, P = 0.014), lactate dehydrogenase (LDH, HR = 1.00, 95% CI was 1.00-1.00, P < 0.001), hydroxybutyrate dehydrogenase (HBDH, HR = 1.00, 95% CI was 1.00-1.00, P = 0.001), creatine kinase (CK, HR = 1.00, 95% CI was 1.00-1.00, P = 0.002), MB isoenzyme of creatine kinase (CK-MB, HR = 1.01, 95% CI was 1.01-1.02, P < 0.001), Na ( HR = 1.02, 95% CI was 0.99-1.05, P = 0.183), blood urea nitrogen (BUN, HR = 1.02, 95% CI was 0.99-1.05, P = 0.139), fibrinogen (FIB, HR = 0.85, 95% CI was 0.71-1.02, P = 0.078), neutrophil ratio (NEU%, HR = 0.99, 95% CI was 0.97-1.00, P = 0.114), platelet count (PLT, HR = 1.00, 95% CI was 0.99-1.00, P = 0.108) and total bile acid (TBA, HR = 1.01, 95% CI was 1.00-1.02, P = 0.096) shown to be associated with poor prognosis. On multivariable analysis, level of PCT was an important factor influencing the outcome of sepsis ( HR = 1.03, 95% CI was 1.01-1.05, P = 0.002). Kaplan-Meier survival curve showed that there was no significant difference with respect to the overall survival between the two groups, with patients of PCT ≤ 0.25 μg/L and PCT > 0.25 μg/L ( P = 0.220). It also showed that the overall survival rate in patients with high APACHE Ⅱ score (> 27 points) was significantly lower than that in patients with low APACHE Ⅱ score (≤ 27 points, P = 0.015). Conclusion:Serum PCT level is valuable prognostic factors of elderly patients with sepsis, and higher APACHE Ⅱ score (> 27 points) indicates a poor prognosis.

Relationship among spontaneous turning direction, balance and fall risk in stroke patients during walking / 中国康复理论与实践

ObjectiveTo investigate the relationship among spontaneous turning direction, balance ability and fall risk in patients with stroke during walking. MethodsFrom December, 2021 to November, 2022, 94 patients with stroke were recruited from Beijing Bo'ai Hospital. They were assessed with simple Timed 'Up and Go' Test (TUGT, TUGT1), TUGT with a cup in hand (TUGT2), and TUGT with calculation task (TUGT3). The spontaneous turning directions at the turn point were recorded, and the patients were divided into no-same group (n = 34) and same group, and the same group was further divided into affected group (n = 33) and unaffected group (n = 27), according to the spontaneous turning direction. After a spontaneous turning of each TUGT, the patients were asked to finish another TUGT turning to the opposite direction. And then, they were assessed with single leg standing test, Functional Reach Test (FRT), 360° turning test and the Morse Fall Scale (MFS). ResultsThere were the most patients with left hemiplegia in the affected group (χ2 = 7.995, P < 0.05). The time of TUGT1, TUGT2 and TUGT3 was the most in the affected group and the least in the unaffected group (F > 4.009, P < 0.05), and it was more in the affected group than in the unaffected group as post-hoc test (P < 0.05). The one leg standing time (H = 9.403, P = 0.009) and FRT distance (F = 4.300, P = 0.016) were the least in the affected group and the most in the unaffected group, and it was less in the affected group than in the unaffected group as post-hoc test (P < 0.05). The turning time (F = 4.134, P = 0.019) and turning steps (F = 5.611, P = 0.003) were the most in the affected group and the least in the unaffected group, and it was more in the affected group than in the unaffected group as post-hoc test (P < 0.05). The score of MFS was the most in the affected group and the least in the unaffected group (H = 8.192, P = 0.017), and it was more in the affected group than in the unaffected group as post-hoc test (P < 0.05). ConclusionThe stroke patients spontaneously turning to the affected side during walking usually are poorer in balance function, and in a risk of fall.

Association of FLG mutation with tumor mutation load and clinical outcomes in patients with gastric cancer.

Background: Stomach adenocarcinoma (STAD) is one of the most frequently diagnosed cancers in the world with a poor prognosis due to genetic heterogeneity. The present study aimed to explore potential prognostic predictors and therapeutic targets that can be used for STAD treatment. Methods: We collected relevant data of STAD patients from the Cancer Genome Atlas (TCGA), including somatic mutation, transcriptome, and survival data. We performed a series of analyses such as tumor mutational burden (TMB), immune infiltration, and copy number variation (CNV) analysis to evaluate the potential mechanism of filaggrin (FLG) mutation in gastric cancer. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, and gene set enrichment analysis (GSEA) were performed for annotation of differentially expressed genes (DEGs). The STRING online database was used to construct the protein-protein interaction (PPI) and ceRNA network and hub genes were identified. Univariate and multivariate Cox regression analyses were used to determine the effect of selected DEGs on tumor prognosis. Results: The FLG-mutant group (FLG-MT) showed a higher mutation load and immunogenicity in gastric cancer. GO and KEGG analyses identified and ranked unique biologic processes and immune-related pathway maps that correlated with the FLG-mutant target. GSEA analysis showed that several tumorigenesis and metastasis-related pathways were indeed enriched in FLG-mutant tumor tissue. Both cell cycle-related pathways and the DNA damage and repair associated pathways were also enriched in the FLG-MT group. The FLG mutations resulted in increased gastric cancer sensitivity to 24 chemotherapeutic drugs. The ceRNA network was established using Cytoscape and the PPI network was established in the STRING database. The results of the prognostic information further demonstrated that the OS and DFS were significantly higher in FLG mutation carriers, and the FLG gene mutation might be a protective factor. Conclusion: The multiple molecular mechanisms of the FLG gene in STAD are worthy of further investigation and may reveal novel therapeutic targets and biomarkers for STAD treatment.

@#Objective To observe the clinical efficacy of simple knee trainer on active knee flexion in patients with hemiplegia after stroke.Methods From March, 2020 to May, 2021, 46 hemiplegics after stroke in Beijing Bo'ai Hospital were randomly divided into control group (n = 23) and experimental group (n = 23). Both groups accepted routine rehabilitation training, and the experimental group accepted knee flexion exercise training in sitting position through the simple knee trainer, for eight weeks. They were measured active knee flexion angle in sitting position and maximum flexion angle in walking before and after training, as well as Holden Functional Ambulation Category (FAC).Results Both active knee flexion angle in sitting position and maximum flexion angle in walking significantly increased in both groups after training (|t| > 6.991, P < 0.001), and increased more in the experimental group than in the control group (t > 2.185, P < 0.05). The grade of FAC also improved in both groups (|Z| > 2.828, P < 0.01), and no significant difference was found between groups (Z = -0.821, P = 0.412).Conclusion The application of simple knee trainer can effectively improve the active range of motion of knee, which may be used in clinic- and community-based rehabilitation.

Effect of aquatic treadmill training on bilateral abdominal muscle thickness and balance function in stroke patients with hemiplegia / 中国康复理论与实践

ObjectiveTo explore the effect of aquatic treadmill training on abdominal muscle thickness and balance function in patients with hemiplegia after stroke. MethodsFrom March to October, 2021, 60 patients with hemiplegia after stroke were randomly divided into control group (n = 20), suspension group (n = 20) and aquatic treadmill group (n = 20). On the basis of comprehensive rehabilitation training, the control group received treadmill training, the suspension group received skyrail suspension walking training, and the aquatic treadmill group received treadmill training in water, for four weeks. The curative effect was evaluated by musculoskeletal ultrasound with muscle thickness of bilateral external oblique, internal oblique and transverse abdominal muscles. And they were assessed with Postural Assessment Scale for Stroke Patient (PASS) and Timed 'Up & Go' Test (TUGT) before and after treatment. ResultsAfter treatment, the thickness of external oblique and internal oblique muscles on the unaffected side, the PASS score and the TUGT time improved in all the three groups (|t| > 2.135, P < 0.05); while the thickness of external oblique, internal oblique and transverse abdominal muscles in the aquatic treadmill training group increased (|t| > 5.567, P < 0.001). The PASS score, the TUGT time, and the thickness of external oblique and internal oblique muscles on the affected side improved more in the aquatic treadmill training group than in the control group and the suspension group (P < 0.05). ConclusionThe aquatic treadmill training is more effective in strenghthening abdominal muscle to improve balance function.

The research progress on silent mating type information regulation 2 homolog-3 and neurodegenerative diseases / 中华神经科杂志

Silent mating type information regulation 2 homolog-3(Sirt3) has a close relationship with neurodegenerative diseases. As researches developing, more and more abnormal proteins have been found depositted in neuron, and these abnormal proteins could induce mitochondrion oxidative stress injury. But Sirt3 could resist abnormal protein′s oxidative stress injury by deacetylation. So Sirt3 may delay the progression of neurodegenerative diseases.

The basic route of the nuclear translocation porcine growth hormone (GH)-growth hormone receptor (GHR) complex (pGH/GHR) in porcine hepatocytes.

Traditional views suggest that growth hormone and the growth hormone receptor (GH/GHR complex) exert their functions only on the plasma membrane. This paradigm, however, has been challenged by recent new findings that the GH/GHR complex could translocate into cell nuclei where they could still exhibit important physiological functions. We also reported the nuclear localization of porcine GH/GHR and their potential functions in porcine hepatocytes. However, the basic path of pGH/GHR's nuclear translocation remains unclear. Combining previous research results and our current findings, we proposed two basic routes of pGH/GHR's nuclear transportation as follows: 1) after pGH binding to GHR, pGH/GHR enters into the cytoplasm though clathrin- or caveolin-mediated endocytosis, then the pGH/GHR complex enters into early endosomes (Rab5-positive), and the endosome carries the GH/GHR complex to the endoplasmic reticulum (ER). After endosome docking on the ER, the endosome starts fission, and the pGH/GHR complex enters into the ER lumen. Then the pGH/GHR complex transports into the cytoplasm, possibly by the ERAD pathway. Subsequently, the pGH/GHR complex interacts with IMPα/ß, which, in turn, mediates GH/GHR nuclear localization; 2) pGH binds with the GHR on the cell membrane and, subsequently, pGH/GHR internalizes into the cell and enters into the endosome (this endosome may belong to a class of endosomes called envelope-associated endosomes (NAE)). Then, the endosome carries the pGH/GHR to the nuclear membrane. After docking on the nuclear membrane, the pGH/GHR complex fuses with the nuclear membrane and then enters into the cell nucleus.

A case-control study of cognitive impairment and related factors among elderly patients / 中国心理卫生杂志

Objective: To explore risk factors for cognitive impairment among elderly patients. Methods: There were 257 qualified subjects recruited, a case-control study was performed by collecting data of Mini Mental State Examination, carotid artery color Doppler flow imaging, biochemical tests, personal information on ages, medical histories, smoking as well as physical exercise among the recruited elderly in-patients/out-patients. A logistic regression was conducted to screen main effects of variables on occurrences of cognitive impairment. Results: Using logistic regression, the carotid intima-media thickness was found to be a significant risk factor (P<0.001) with larger regression coefficients (15.105 - 22.065) for the occurrence of cognitive impairment among elderly; about 71％ -78％ and 4％ decrease in risks of dementia occurrence for every 1 pg/mL serum free triiodothyronine and lkg body weight increase. Conclusion: The increase in carotid intima-media thickness is a significant risk factor for the occurrence of cognitive impairment among elderly patients. The decrease in serum free triiodothyronine and body weight are the related factors to increase risk for dementia.
