The anti-fatigue ability decline is one of the most important clinical symptoms of chronic exertional compartment syndrome (CECS). The percentage change of type-I and II skeletal-muscle fiber is an important reason for anti-fatigue ability decline after intracompartmental pressure increase. There is a close relationship between CaN-NFAT or PPAR/PGC-1 signaling pathways and muscle fiber type conversion. Studies have confirmed that Traditional Chinese medicine can protect the body tissue by activing CaN-NFAT or inhibiting PPAR/PGC-1 signaling pathways. Therefore, we wrote the review in order to better analyze the research progress in this field.

Objective To evaluate the efficacy and safety of efavirenz-based therapy in patients with human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection. Methods Fiftythree HIV/HCV co-infected patients received efavirenz-based therapy were followed up for 7 years.The changes of CD4+ T lymphocyte count, HIV virus load, hepatic function, hepatic fibrosis index,blood lipid, blood glucose, blood uric acid and blood routine were observed. The comparison of means before and after treatment was performed by t-test. Results The HIV RNA levels at baseline and endpoint were (4. 56±0. 88) lg copy/mL and (1.70±1.10) lg copy/mL, respectively (t=14. 781, P<0.01). The peripheral blood CD4+ T lymphocyte counts were ( 188.37±151.14)×106/L and (445.18±314.25)×106/L, respectively (t=5.362, P<0.01).The alanine aminotransferase (ALT) levels were (36.6±16.3) U/L and (57.2±9.9) U/L, respectively (t=7.864, P<0. 01).The glycocholic acid levels were (444.22±476.74) mg/L and (556.88±733.05) mg/L, respectively (t=0.938, P<0.05). The Ⅳ-collagen(Ⅳ-C) levels were (45.13±8.25) ng/mL and (47.88±4.51) ng/mL, respectively (t= 2.129, P<0.05). The riacylglycerol levels were (1.57±0.65)mmol/L and (2.51±1.29) mmol/L, respectively (t=4.737, P<0.01). The blood uric acid levels were (298.5±48.2) mmol/L and (495.1±89.4) mmol/L, respectively (t= 14.092, P<0.01).Conclusions The efavirenz-based therapy is efficacious in HIV/HCV co-infected patients, but it could cause liver injury and metabolic disorder.

Objective To analyze the clinical value of 16-row multislice CT in the live kidney donor preoperative assessment. Methods Thirty-six kidney donors underwent 16-slice CT preopera-tive assessment. The non-enhanced, arterial phase, venous phase and excretory phase examinations were performed. Two radiologists independently studied renal vessels and urinary system of each case by maximum intensity projections and volume rendering techniques. The specificity and accuracy of 16-row muhislice CT in the evaluation o{ renal vessels and urinary system were calculated after comparing with surgical findings as reference. Results 16-row muhislice CT found 7 variant renal arteries. One variant artery confirmed in surgery was missed in the CT study. 16-row muhislice CT made cor-rect diagnosis of all variant anatomy of renal veins and ureters which were confirmed in surgery. For i-dentification of variant anatomy of renal arteries, veins and ureters, the specificity of 16-slice CT was 100% (29/29), 100% (32/32), and 100% (35/35), the overall accuracy was 97%(36/37), 100% (36/ 36), and 100%(36/36), respectively. Conclusions 16-row muhislice CT shows excellent value in the evaluation of renal vessels and urinary system in live kidney donors. 16-row multislice CT is suit-able for the noninvasive examination in live kidney donor preoperative assessment and provides all sup-portive and relevant information required by the surgeons.

Objective:To investigate the diagnostic performance of Xpert Mycobacterium tuberculosis/rifampin (Xpert MTB/RIF) assay for pulmonary tuberculosis (TB) in patients with acquired immunodeficiency syndrome (AIDS). Methods:Clinical data of 226 patients with AIDS and suspected pulmonary TB in Shanghai Public Health Clinical Center, Fudan University from July 2017 to November 2019 were retrospectively analyzed. Fluorescence staining microscopy of sputum smear, BACTEC MGIT 960 liquid culture (or Roche solid culture) and Xpert MTB/RIF assay were implemented respectively. The sensitivity and specificity of Xpert MTB/RIF in the diagnosis of Mycobacterium tuberculosis (MTB) infection and rifampin resistance were analyzed. Results:Totally 226 patients of suspected pulmonary TB were enrolled. There were 94(41.6%) patients had positive mycobacterium culture, in which 51 (54.3%) were MTB and 43 (45.7%) were nontuberculous mycobacteria (NTM). Using the positive MTB culture of sputum and mycobacterial protein from BCG of Rm 0.64 in electrophoresis (MPB64) as reference standard, the sensitivity and specificity of Xpert MTB/RIF assay for MTB diagnosis were 72.6%(95% confidence interval ( CI) 66.7%-78.4%) and 97.1% (95% CI 95.0%-99.3%), respectively. The sensitivity and specificity of Xpert MTB/RIF assay for MTB diagnosis in patients with positive sputum smear were 76.7%(95% CI 67.7%-85.8%) and 90.0(95% CI 83.6%-96.5%), respectively. The sensitivity and specificity of Xpert MTB/RIF assay for MTB diagnosis in patients with negative sputum smear were 50.0%(95% CI 41.8%-58.2%)and 99.3%(95% CI 97.9%-100.0%), respectively. With phenotypic resistance as reference standard, the sensitivity and specificity of Xpert MTB/RIF assay for rifampicin resistance were 75.0% and 100.0%, respectively. Conclusion:Among AIDS patients, the performance of Xpert MTB/RIF assay for pulmonary TB diagnosis is pretty good and could differentiate MTB from NTM rapidly, which has good application value.
