ObjectiveTo evaluate the clinical efficacy of Xu's Shenqiyizhu （SQYZ） decoction combined with chemotherapy in the treatment of cancer-related fatigue （CRF） of stagnated-toxin spleen deficiency type after gastric cancer surgery and explore its possible mechanism. MethodsFifty postoperative gastric cancer patients with CRF of stagnated-toxin spleen deficiency type were selected and randomly divided into an experimental group and a control group by using a random number table，with 25 cases in each group. The control group was treated with FLOT chemotherapy （50 mg·m^-2 docetaxel （iv drip on day 1） + 85 mg·m^-2 oxaliplatin （iv drip on day 1） + 200 mg·m^-2 calcium folinate （iv drip on day 1） + 2 600 mg·m^-2 fluorouracil （iv drip for 24 h on day 1），once every three weeks） and basic and symptomatic supportive treatment. The experimental group was treated with Xu's SQYZ decoction （decocted twice，200 mL taken orally twice a day） in addition to the treatment of the control group. One course of treatment lasted for three weeks，with a total of four courses conducted. Observation was performed on the piper fatigue scale （PFS） scores，karnofsky performance status （KPS） scores，European Organization for Research and Treatment of cancer quality of life questionnaire （EORTC QLQ-C30） scores，traditional Chinese medicine syndrome scores，and serum levels of tumor necrosis factor-α （TNF-α），interferon-γ （IFN-γ），and interleukin-6 （IL-6）detected via enzyme linked immunosorbent assay （ELISA） before and after treatment in the two groups. The safety test results before and after treatment for the two groups of patients，as well as the occurrence of adverse events during treatment， were recorded. Transcriptome sequencing data of peripheral blood samples from gastric adenocarcinoma patients and normal individuals were downloaded from the gene expression omnibus （GEO） database，and differentially expressed genes between the tumor and normal groups were identified. Differential gene enrichment analysis was made based on the Kyoto Encyclopedia of Genes and Genomes （KEGG） and Gene Ontology （GO）. The CRF relevance scores of genes were retrieved from the GeneCards database. Results① Compared with that before treatment，the total PFS score in the experimental group was significantly reduced （P<0.05）. Compared with the control group after treatment，the experimental group showed significantly reduced total PFS score （P<0.05）. ② Compared with that before treatment，the KPS score in the experimental group decreased significantly （P<0.05）. Compared with the control group after treatment，the experimental group exhibited a significantly decreased KPS score （P<0.05）. The experimental group demonstrated significantly increased functional scores （physical function，role function，emotional function，social function，and overall health） （P<0.05） and significantly reduced symptom scores （fatigue，shortness of breath，loss of appetite，constipation，and diarrhea） of the EORTC QLQ-C30 scale after treatment compared with before treatment. Compared with the control group after treatment，the experimental group presented significantly increased functional scores （physical function，emotional function，social function，and overall health） （P<0.05） and significantly reduced symptom scores （fatigue，nausea and vomiting，shortness of breath，loss of appetite，and diarrhea） of the EORTC QLQ-C30 scale （P<0.05）. Compared with those before treatment，the traditional Chinese medicine syndrome scores （eating too little and poor digestion，fatigue and weakness，postprandial bloating，abnormal bowel movements，lassitude and weakness，and total score） in the experimental group were significantly reduced （P<0.05）. Compared with the control group after treatment，the experimental group had significantly reduced traditional Chinese medicine syndrome scores （eating too little and poor digestion，fatigue and weakness，nausea and vomiting，and sallow complexion） （P<0.05）， which indicated better efficacy in the experimental group than in the control group （χ²=7.996，P<0.05）. The serum levels of TNF-α，IL-6，and IFN-γ were significantly correlated with each other （P<0.01）. Compared with those before treatment，the levels of serum cytokines TNF-α，IL-6，and IFN-γ in the experimental group were significantly reduced （P<0.05）. Compared with the control group after treatment，the experimental group showed significantly reduced serum levels of cytokines TNF-α，IL-6，and IFN-γ （P<0.05）. ③ There were no significant intra-group and inter-group differences in the safety test results of the two groups before and after treatment. During the treatment period，there was no significant difference in the incidence of adverse reactions between the two groups of patients. ④ Compared with the normal group，the tumor group exhibited a total of 328 significantly up-regulated genes in the peripheral blood （P<0.05），and KEGG and GO analyses showed that they were significantly enriched in signaling pathways such as TNF （P<0.05）. ⑤ TNF，IL6，IFNG， and other cytokine encoding genes may be key pathogenic genes for CRF. ConclusionXu's SQYZ decoction can alleviate symptoms such as fatigue in postoperative chemotherapy patients with gastric cancer and improve their functional status and quality of life. Its mechanism may be related to improving cytokine imbalance.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Dermatomyositis is an autoimmune disease mainly involving the skin and muscles, as well as the heart, lungs, and joints, and it may also be complicated by malignant tumors. Among these complications, interstitial lung disease (ILD) is of particular concern. Because of the urgent onset and rapid progress, ILD is hard to diagnose at the early stage, usually leading to treatment delay. Furthermore, ILD is the common cause of death in patients with dermatomyositis. This review summarizes types of skin lesions of, serum biomarkers for and radiological features of dermatomyositis to help evaluate the risk, severity and prognosis of it complicated by ILD.

Objective:To explore the effectiveness and safety of comprehensive treatment of type 2 diabetes mellitus (T2DM) based on syndrome differentiation and diet.Methods:Prospective clinical study. A total of 147 patients with T2DM from September 2021 to August 2022 who met the inclusion criteria were included in the self-controlled trial.

ROC curve analysis revealed that GBP1 might have important value in early diagnosis of pTB．GSEA analysis suggested that the hyper-expression of GBP1 was closely related to the host inflammatory response，IFN-γ/ α signaling pathway and TNF-α/ IL-6 signal transduction． Conclusion GBP1 is highly expressed in pTB tissues and is involved in the process of inflammatory response and host anti-tuberculosis infection ; GBP1 may be used as an early diagnostic marker or therapeutic target for pTB.

Objective:To explore the application value of the new gastric cancer screening scoring system for risk populations in the island of Fujian province.Methods:From April to June 2019, gastric cancer screening was performed on the population of Nanri Island, Putian City, Fujian Province, and epidemiological data of all subjects were prospectively collected. Participants underwent gastroscopy based on gastric cancer risk stratification of the new scoring system. Suspected positive cases further received magnifying endoscopy and biopsy. Additional endoscopic procedures and other surgical treatments were conducted. The detection rates of gastric cancer and precancerous lesions in each group of gastric cancer risk stratification were compared, and the Chi-square test was used for statistical analysis.Results:A total of 1 423 subjects were included, and 19 cases (1.34%) of gastric cancer were detected. The detection rates of gastric cancer were 0.88% (9/1 025) in the low-risk group, 1.76% (6/341) in the medium-risk group, and 7.02% (4/57) in the high-risk group. Paired comparison between the low-risk group and the high-risk group showed significant difference ( χ2=12.364, P=0.003). There was no significant difference between the low-risk group and medium-risk group, or between the medium-risk group and high-risk group ( P>0.05). Among all participants, 87 (6.11%) cases of gastric precancerous lesions were identified. The detection rates of precancerous lesions in the low-risk, medium-risk, and high-risk groups were 6.24% (64/1 025), 5.87% (20/341), and 5.26% (3/57) respectively, with no significant difference among the three groups ( P>0.05) .Conclusion:During gastric cancer screening, the novel gastric cancer screening scoring system helps to stratify gastric cancer risk for population in the islands of Fujian province, serving as a foundation for subsequent detailed endoscopy.

Objective:To investigate the role and mechanism of chemokine receptor type 4 (CXCR4) in renal injury and fibrosis caused by calcium oxalate crystals in mice.Methods:In June 2021, Fifteen male C57/BL6 mice were divided into control group (5 mice), model group (5 mice), and AMD3100 intervention group (5 mice) by random number table method. In model group and AMD3100 intervention group, glyoxylate (100 mg/kg) was injected intraperitoneal for 7 consecutive days for modeling. Meanwhile, the AMD3100 intervention group was also given intraperitoneal injection of AMD3100 (1 mg/kg) for 7 days. The control group was continuously injected with equal volume saline intraperitoneally. After 7 days, peripheral blood was collected from each group to determine the levels of serum urea nitrogen (BUN) and creatinine (Scr) to assess the renal function; HE, Von-Kossa, Picrosirius Red staining was also taken from the left kidney to observe the pathological changes of renal tissue. CXCR4, transforming growth factor β1 (TGF-β1) were detected by immunohistochemistry and western blot. The expression levels of PI3K/AKT pathway-related proteins were detected by western blot.Results:The results of biochemical indexes showed that the serum Scr [(108.03±13.56) μmol/L vs. (39.50±4.48)μmol/L, P<0.01)] and BUN[(5.66±0.48)mmol/L vs. (0.77±0.10)mmol/L, P<0.01) levels were significantly increased in model group compared with the control group. The AMD3100 intervention group was significantly lower than the model group in terms of Scr [(65.77±3.27)μmol/L vs. (108.03±13.56)μmol/L, P<0.05) and BUN [(2.97±0.44)mmol/L vs. (5.66±0.48)mmol/L, P<0.05) levels. The results of kidney pathology in mice showed that renal tubules were significantly dilated with inflammatory cell infiltration in the model group compared with the control group, and a large number of calcium oxalate crystals and collagen fibers were deposited. The extent of kidney damage, calcium oxalate crystals and collagen fibers deposition were significantly reduced in the AMD3100 intervention group compared with the model group. The results of western blotting showed that the relative expression of CXCR4(0.639±0.019 vs. 0.158±0.012, P<0.01) and TGF-β1(0.698+ 0.018 vs. 0.314+ 0.015, P<0.05) was significantly increased in the model group compared with the control group. The relative expression of CXCR4(0.322±0.231) in the AMD3100 intervention group compared with the model group (0.322±0.231 vs. 0.639±0.019, P<0.05) and TGF-β1(0.445+ 0.017 vs. 0.698+ 0.018, P<0.05) were significantly decreased. The results of immunohistochemical staining showed the trend of CXCR4 and TGF-β1 expression in each group consistent with the results of protein blotting assay. Western blotting results showed that the expression of p-PI3K (0.613±0.016 vs. 0.213±0.011, P<0.01) and p-AKT(0.149±0.013 vs. 0.047±0.014, P<0.01) was significantly increased in the model group compared with the control group. The expression of p-PI3K in the AMD3100 intervention group compared with the model group (0.292±0.020 vs. 0.613±0.016, P<0.05) and p-AKT (0.098±0.021 vs. 0.149±0.013, P<0.05)was significantly decreased. Conclusion:CXCR4 inhibits calcium oxalate crystal-induced kidney injury and interstitial fibrosis in mice by targeting the PI3K/AKT pathway.

Objective Assess and determine inactivation effect of heat,.ultraviolet (UV) light and three disinfectants against human infected H9N2 avian influenza virus in laboratory.Methods Suspension containing with 1010.67 TCID50/ml viral was exposed to 50 ℃,56 ℃,60 ℃,65 ℃ for 10 to 60 minutes and UV every 10 interval minutes from 10 to 80 minutes.The residual viruses after physical treatment were determined through half of tissue culture infective dose (TCID50) with MDCK cells and calculated by Reed-Muench method.Suspension with 1010.37EID50/ml quantitative virus was applied to equal volume of 10％ 84 sanitizer,75％ ethanol,1％ Virkon solution and incubated for 1 minute to 15 minutes respectively.The residual viral activity would be evaluated by inoculating in SPF chicken embryo.When the virus titer dropped by 4 lgTCID50/ml or virus in chicken embryo culture was observed to be negative,the physical and chemical treatment was considered effective.Results Human infected H9N2 avian influenza virus titer decreased by 4.02 lgTCID50 at 56 ℃ for 15 minutes,and after 30 minutes at 56 ℃ or 10 minutes at 60 ℃/65 ℃,the post-viral titer would decline below the detection level.20 minutes of UV irradiation would lead to a 5.67 log reduction,and after 70 minutes lighted,the virus titer fell below the detection level.Virus proliferation was not detected after 3 minutes of disinfection with 10％ 84 sanitizer,75％ ethanol and 1％ Virkon.Conclusions We should note that it is necessary to meet the specific condition to effectively inactivate the human infected H9N2 avian influenza virus.Our study provides an experimental basis for the biosafety operation of human infected H9N2 avian influenza virus.

Objective To investigate the value of DWI in the evaluation of the therapeutic effect of cyber knife in the treatment of hepatocellular carcinoma.Methods Ninety patients who were clinically diagnosed with hepatocellular carcinoma (95 lesions) in the 5th Medical Center of General Hospital of PLA from February 2011 to December 2013 were retrospectively analyzed. All 90 patients underwent pre‐treatment dynamic contrast‐enhanced MRI scans of liver. Fourty six of them underwent liver MRI scan 3 months after treatment with cyber knife, and 49 patients underwent liver MRI scans 6 months after treatment. According to the evaluation criteria of solid tumor effect, complete necrosis tumor lesions and postoperative residual active lesions were determined. The ADC values of residual active tissue lesion, necrosis lesion in tumor and normal liver were measured. Paired sample t test was used to compare the difference of ADC values of tumor necrosis lesions and normal liver tissues between 3 and 6 months after treatment and before treatment, and ROC was used to evaluate the efficacy of ADC values in predicting complete tissue necrosis after treatment. Results In the 95 lesions, 91 lesions were completely necrotic, and active tissues were found in 4 lesions after treatment. There were statistically significant differences in the ADC values of the lesions at 3 and 6 months after treatment and before treatment (P<0.05),and the ADC values of the tissues after treatment were higher than those before treatment. There was no statistically significant difference in ADC values between 3 and 6 months after treatment and before treatment in normal liver tissue (P>0.05). The area under the ROC of using ADC value to predict the complete necrosis after treatment with cyber knife was 0.767, and the ADC value was 1.23×10‐3 mm2/s as the diagnostic cutoff value. The sensitivity and specificity of the diagnosis were 76.5% and 70.6%, respectively. Conclusion ADC values can distinguish the necrotic component from the active component of hepatocellular carcinoma after treatment, and can be used to evaluate the therapeutic effect of cyber knife in hepatocellular carcinoma.

Objective To explore the clinical significance of fused renal pyramid (FRP) structure in the establishment of percutaneous renal access.Methods From May 2017 to April 2018,10 fresh porcine kidneys were selected to cast in blood vessels for grading the kidney artery.Then another 80 isolated porcine kidueys were used to simulate percutaneous renal pu ncture and dilatation to establish F24 operative access by the same surgeon.Under the endoscope and microscope,we compared the effects of four different puncture paths on the occurrence of renal vascular injury when respectively punctured through the normal renal pyramid (group A),the side of the FRP (group B),the centre of the FRP (group C) and the renal column (group D).Results The kidney arteries can be divided into six grades,there is grade Ⅳ branchinterlobar artery walking inside the FRP.The diameter of interlobar artery in the FRP was significantly smaller than that in the renal column (0.442 ±0.012) mm vs.(0.778 ±0.037) mm,(P ＜0.001).Endoscopic observation and pathological tissue section showed the following results.In group A,there was no injured blood vessel distributed along the access.There were six specimens with grade Ⅴ or Ⅵ arteries injury in the cortex.Owing to the small size of the renal pyramid and the inaccurate location of the puncture,there was also injury associated with a normal grade Ⅳ artery in the renal column.In group B,there was a certain distance between the tract and the grade Ⅳ artery that distributed in the FRP,injury was still noticed in four specimens.And six specimens have grade Ⅴ/Ⅵ arterial injury.As the distance between the tract and the renal column decreased,there was a case in which a simultaneously injury occurred to the extremity of a grade Ⅲ artery and a grade Ⅳ artery.In group C,there was a white thin strip of connective tissue exposed along the puncture tract.Ectopic grade Ⅳ artery injury occurred in fourteen specimens,and grade Ⅴ/Ⅵ artery injury occurred in seven specimens.In group D,there were grade Ⅲ to Ⅵ arteries distributed along the operational access,which was cowered with white fat and connective tissue.The number of arteryinjury in grades Ⅲ,Ⅳ,and Ⅴ/Ⅵ were4,19,and 5,respectively.The mean ranks of artery injury degree in groups A (17.0),B (30.1),C (33.5) and D (41.5) gradually increased,and the difference was significant (P =0.006).There was a significant difference between group A and C (P =0.018),while no significant difference between group A and B (P =0.122),groups C and D (P =0.072).The proportion of grade Ⅳ artery injury in group A,B,and C was 5％ (1/20),25％ (5/20),and 70％ (14/20),respectively.There was a significant difference between group A and C (P =0.029),while no significant difference between group A and B (P =0.316).There was no significant difference in the injury of grade Ⅴ and Ⅵ artery in four groups (P =0.827).Conclusions When establishing a percutaneous renal access,vascular injury caused bv puncturing through the FRP cannot be ignored.It is necessary to carefu lly identify and bypass the FRP when selecting the puncture path.If unavoidable,the puncture path shoull be on the centreline of one side pyramid of the FRP.
