Objective:To explore the application value of renal artery resistance index in the diagnosist of intra-abdominal hypertension (IAH) in critically ill patients.Methods:89 patients with risk factors of IAH in the intensive care unit of Zhangzhou Hospital Affiliated to Fujian Medical University from February 2022 to June 2022 were retrospective analyzed. The intra-abdominal pressure (IAP) were measured by bladder, and patients divided into IAH group (IAP≥12 mmHg) and non-IAH group (IAP <12 mmHg). The resistance index (RI) of the right renal aorta, segment artery and interlobar artery were measured by color Doppler ultrasound. The difference between the measurement indicators of patients in the IAH and non-IAH groups and the correlation with IAP were analyzed. As for different indicators to predict the diagnostic efficacy of IAH, ROC curve analysis was used to evaluate the effect. And further multivariate logistic regression analysis was to find independent risk predictor.Results:A total of 89 patients were included in the study, including 44 patients with normal IAP and 45 patients diagnosed IAH. There were significant differences in the right renal aorta, segmental artery and interlobar artery RI (all P<0.01). The interlobar artery RI≥0.698 was the highest diagnostic cut-off,area under the curve was 0.914, sensitivity was 82.2%, specificity was 97.7%, and Jordon index was 0.799. The Spearman correlation analysis of IAP and the ultrasonographic measurements revealed a strong correlation between right renal interlobar artery RI and IAP ( r=0.741, P<0.01). The multivariate logistic regression analysis showed that the right renal interlobar artery RI ( OR= 24.472, 95% CI:5.122~116.919, P<0.01) was an independent risk predictor of IAH ( P<0.01). Conclusion:Right renal interlobar artery RI had better diagnostic efficacy of IAH,renal ultrasound could be used as an alternative, non-invasive technique for the diagnosis and follow-up of IAH.

Objective:To explore the efficacy of online pulmonary rehabilitation (PR) management among community-dwelling patients with stable chronic obstructive pulmonary disease (COPD).Methods:This study was a single-center randomized controlled trail with an unblinded design. A total of 130 patients with stable COPD who visited Zhuanqiao Community Health Service Center in Shanghai Minhang District from October 2020 to March 2022 were randomly divided into study group and control group with 65 cases in each group. Both groups received conventional treatment, while patients in study group attended online rehabilitation management, including face-to-face rehabilitation instruction and multiple online guidance. Pulmonary ventilation function including forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1) and percentage of forced expiratory volume in the first second to forced expiratoty volume (FEV 1%pred), modified British Medical Research Council Dyspnea Scale (mMRC), chronic obstructive pulmonary disease assessment test (CAT), score of 6 minutes walking distance (6MWD) and DOSE (dyspnea, degree of airflow obstruction, smoking status, the number of exacerbation) index were measured at baseline and after 8 weeks of rehabilitation, and compared between two groups. Results:The baseline data of the two groups were comparable. After 8 weeks of management, FVC, FEV 1, FEV 1%pred, mMRC, CAT, 6MWD and DOSE index of both groups were improved compared with the baseline level(control group: t=-7.799, -7.581, -9.010, 3.565, 9.887, -16.677, 3.795; study group: t=-12.623, -13.914, -17.644, 7.404, 22.457, -26.826, 7.968; all P<0.05). The FEV 1%pred, CAT and 6MWD in the study group were better than those in the control group ( t=-2.939, 2.277,-2.130, all P<0.05); while there were no significant differences in FVC, FEV 1, mMRC and DOSE index between the two groups( t=-0.162, -1.280, 0.925, 1.939,all P>0.05). Conclusions:The online pulmonary rehabilitation management can better improve lung function, dyspnea symptoms and exercise tolerance of patients with stable COPD, which can be used for rehabilitation training and management of community-dwelling patients.

Purpose To explore the application of contrast-enhanced ultrasound in evaluating the local muscle microcirculation before and after acupuncture at Zusanli point in normal people.Materials and Methods A total of 72 healthy volunteers who visited the Department of Ultrasound,the Second Affiliated Hospital of Fujian Medical University from September 2018 to May 2020 were prospectively collected,all subjects performed ultrasound contrast before acupuncture,acupuncture with strongest deqi,and two hours after acupuncture to observe the blood flow perfusion of the microvessels in the tibialis anterior muscle.The pre-selected areas of interest the small arteries,muscle tissues and venules in the middle were analyzed to obtain the time-intensity curve and contrast transit time(CTTs)perfusion parameters.Needle sensation was evaluated using objective scoring criteria for acupuncture combined with moxibustion recipients.Gastrin,plasma gastrin,cholecystokinin,and secretin were measured in all subjects before acupuncture,when acupuncture had the strongest deqi,and two hours after acupuncture.Results ①CTTs of arterial-muscle,muscle-venous and arterial-venous of the tibialis anterior muscle at acupuncture with strongest deqi were significantly shorter than those at before acupuncture and two hours after acupuncture(all P<0.001),and there was no significant difference in CTTs before and after acupuncture and moxibustion(P>0.05);②when acupuncture deqi was strongest,serum gastrin,plasma prokinetics,cholecystokinin,and secretin were significantly increased compared with those before acupuncture and two hours after acupuncture,with statistically significant difference(all P<0.001),while there was no significant difference in these parameters between before acupuncture and two hours after acupuncture(P>0.05);③when acupuncture had the strongest deqi,there were positive correlations between gastrin,plasma prokinetic hormone,cholecystokinin,and secretin values and CTTs of arterial-muscle,muscle-venous,and arterial-venous(r=0.360-0.702,P<0.001).Conclusion Acupuncture of the Zusanli,when it gains the strongest deqi,can cause changes in the microcirculation around the skeletal muscle,leading to a significant shortening of CTTs,and also promotes the secretory function of the gastrointestinal tract.

Objective To explore the values of translocator protein (TSPO) and serum cell-free mitochondrial DNA (cf-mtDNA) in predicting the disease condition and prognosis of patients with traumatic shock. Methods Eighty patients (traumatic shock group) with traumatic shock and eighty patients (without traumatic shock group) without traumatic shock were selected. Complete demographic and clinical laboratory data of patients were collected. Blood samples of patients with traumatic shock were collected at the time points of immediately after admission (T₁) and the first day (T₂), the third day (T₃) and seventh day (T₄) after admission, the level of TSPO was measured by enzyme-linked immunosorbent assay (ELISA), and level of cf-mtDNA was measured by quantitative real-time polymerase chain reaction (qPCR). The levels of TSPO and cf-mtDNA were compared between patients with and without traumatic shock; the patients with traumatic shock were divided into the poor prognosis group and good prognosis group according to differed prognostic outcome, and the levels of TSPO and cf-mtDNA were compared between the two groups. The predictive values of TSPO and cf-mtDNA for the prognosis of patients with traumatic shock were analyzed by the receiver operating characteristic (ROC) curve. Results Compared with the no traumatic shock group, the traumatic shock group had higher levels of serum TSPO at T₁ to T₄ and higher levels of cf-mtDNA at T₂ to T₃, and the differences were statistically significant (P < 0.05). Compared with the good prognosis group, the poor prognosis group had higher levels of serum TSPO and cf-mtDNA at T₁ to T₄, and the differences were statistically significant (P < 0.05). Taking the prognosis of traumatic shock patients as the state variable to perform ROC curve analysis, the results showed that the area under the curve (AUC) of TSPO from T₁ to T₄ for predicting prognosis in the poor prognosis group was 0.825, 0.829, 0.695 and 0.869 respectively, while those of cf-mtDNA level from T₁ to T₄ for predicting prognosis in the poor prognosis group was 0.766, 0.766, 0.837 and 0.783 respectively, and the differences were statistically significant (P < 0.001). Conclusion Traumatic shock patients have elevated levels of TSPO and cf-mtDNA, with significantly higher levels observed in those with poor prognosis, and the TSPO level on the seventh day and cf-mtDNA level on the third day have the highest predictive value for prognosis.

Dickkopf-1 (DKK1) is a secreted glycoprotein that acts as an inhibitor of the Wnt/β-catenin pathway and plays an important role in embryonic development, neurogenesis and synaptogenesis. After cerebral ischemia, DKK1 inhibits neurogenesis and angiogenesis by promoting neuronal apoptosis and blood-brain barrier damage, thus aggravating brain injury. In addition, serum DKK1 in patients with ischemic stroke was associated with different disease stages and outcomes. Therefore, the development of specific inhibitors targeting DKK1 is expected to be applied in the treatment of ischemic stroke.

Objective:To analyze the clinical features of patients with pyogenic liver abscess (PLA) and the application of mNGS in PLA, thus to provide reference for clinical diagnosis and treatment.Methods:The demographic and clinical data of 549 patients with liver abscess admitted to Zhongshan Hospital Affiliated to Fudan University from December 2015 to June 2020 were analyzed retrospectively. According to the detection of Klebsiella pneumoniae in 246 patients with positive etiological test results, the patients were divided into two groups: KPLA group and nKPLA group, and clinical characteristics of the two groups were compared. At the same time, the application value of mNGS in PLA was analyzed.Results:Among the 549 patients, the main clinical symptom of PLA was fever ( n= 503, 91.6%) and other clinical symptoms included chills and abdominal pain. Most patients had a single abscess ( n= 464, 84.5%) located in the right lobe ( n = 368, 67.0%), with a size between 5 and 10 cm ( n= 341, 62.1%). A total of 246 patients had positive etiological test results, including 202 KPLA patients which was the main pathogen of liver abscess. The prevalence of diabetes and fatty liver was higher in KPLA patients ( P < 0.05), but there were more culture of liver positive factors in nKPLA patients ( P < 0.001). Among the 109 patients with traditional microbiological results, 92 patients were suspected to KPLA (Klebsiella pneumoniae), of which 14 patients (15.2%) were multidrug resistant (MDR) infection; 17 patients were suspected to nKPLA, of which 10 patients (58.8%) were MDR infection; the incidence of MDR infection in patients with nKPLA was significantly higher than that in patients with KPLA ( P < 0.05). The positive rate of mNGS in plasma was 85.2%, the positive rate of traditional microbial culture in plasma was 14.8%, the positive rate of mNGS in pus was 96.2% and traditional microbial culture in pus was 65.4%. The positive rate of traditional culture was significantly lower than that of mNGS ( P < 0.05). Conclusions:PLA is usually manifested as fever, single and at the right lobe of the liver. Klebsiella pneumoniae is the most common pathogenic bacteria of PLA, which is more common in patients with diabetes and fatty liver, while non-Klebsiella pneumoniae is relatively more common in patients with culture of liver positive factors. The positive detection rate of mNGS is high, which has a unique advantage in pathogen detection.

Objective:To analyze the correlation between the muscle thickness (MT) and echo intensity (EI) of the medial head of gastrocnemius and muscle mass, strength and functional parameters, and to evaluate the diagnostic efficacy of MT and EI for decreased muscle mass.Methods:Fifty-two subjects who visited the Department of Ultrasound Medicine of the Second Affiliated Hospital of Fujian Medical University from March to December 2021 were collected.MT of the medial head of gastrocnemius was measured by two-dimensional ultrasound, and EI values in the region of interest were analyzed using Image J software. Twenty of the subjects were selected to assess the intra-observer and inter-observer agreements in measuring MT and EI values using the intraclass correlation coefficient (ICC) and Altman-Bland analysis was performed. The subjects were divided into healthy control group (30 cases) and decreased muscle mass group (22 cases) according to 2019 Asian Sarcopenia Working Group (AWGS) diagnostic criteria, the differences in MT and EI values between the two groups were compared, and the correlation between MT, EI values and muscle mass, strength, function were analyzed using Pearson correlation analysis. The diagnostic cutoff values of MT and EI values for decreased muscle mass were obtained using ROC curves, and the diagnostic efficacy was compared.Results:①The ICC of MT and EI in medial head of gastrocnemius detected by the same physician and different physicians were greater than 0.97, and the retest reliability was good. ②Compared with the healthy control group, the MT value in medial head of gastrocnemius decreased and the EI value increased in the decreased muscle mass group ( t=4.759, -3.789; all P<0.001). ③The MT value in medial head of gastrocnemius was positively correlated with appendicular skeletal muscle mass (ASM), appendicular skeletal muscle mass index (ASMI), lower limb skeletal muscle mass (LLSM), grip strength, and gait speed ( r=0.579, 0.568, 0.585, 0.495, 0.415; all P<0.001), of which, the correlation with LLSM was the best; ④EI in medial head of gastrocnemius was negatively correlated with ASM and ASMI, LLSM, grip strength, and gait speed, ( r=-0.583, -0.591, -0.590, -0.537, -0.455; all P<0.001), and among which the correlation with ASMI was the best. ⑤The medial head of gastrocnemius MT and EI were 14.33 mm and 58.85 for predicting decreased muscle mass, respectively, and there was no significant difference in the diagnostic performance of the two for decreased muscle mass ( Z=0.734 3, P>0.05). Conclusions:The MT and EI values of the medial head of gastrocnemius can accurately assess muscle mass and can be used in the evaluation of patients with decreased muscle mass.

Objective:To explore a fast method to identify and confirm suspected clonorchis sinensis infection.Methods:For suspected clonorchis sinensis infection, the clonorchiasis serum antibody was detected first with ELISA. If the antibody was positive, the fecal examination for eggs was performed. If the fecal examination was negative, duodenal drainage under gastroscopy was recommended to detect eggs from the drainage fluid.Results:A total of 126 patients met the requirements and aged 54.14±13.33 (24- 87). There were 83 cases (65.87%, 83/126) with eggs positive in the drainage fluid, of which 53 cases were male, aged 55.91±11.47 (30-86), and 30 cases female, aged 55.87± 13.85(30-87). There was no significant difference in age between males and females( P>0.05). The time of catheterization (T1) of 126 cases was 3.79 ±1.45 min. The time of drainage (T2) of 126 cases was 31.39 ±14.29 min. There was no significant difference in T1 or T2 between the positive group and the negative group( P>0.05). The detection rates of eggs were 91.57% (76 cases) in intrahepatic bile duct drainage, 81.93% (68 cases) in the bile-cyst juice and 75.90% (63 cases) in the common bile duct fluid. No serious adverse reactions occurred during or after the operation. Conclusion:The detection rate of clonorchiosis sinensis can be effectively improved by the combination of clonorchiasis serum antibody test and gastroscopy-guided duodenal drainage.
