The abdominal visceral fat content in obese SD rats induced by high fat diet for 10 weeks was significantly higher than that in control group [(26±6 vs 13±3)g,P<0.01] ,along with increased CRP mRNA expression in abdominal visceral fat (0.901±0.085 vs O. 402±0.036, P<0.01). As compared with normal control group, in the high fat group the concentrations of CRP in portal vein [(743.8±95.8 vs 558.3 ±118.3) mg/L, P<0.01] and peripheral vein[(596.3±38.9 vs 485.8±30.2) mg/L,P<0. 05] were higher. The concentration of CRP in portal vein was significantly higher than that in peripheral vein in high fat diet group(P<0.01) ,but this was not evident in control group. These results suggest that the increased CRP expression in visceral adipose tissue may partially account for the elevation of serum CRP in obesity.

OBJECTIVETo investigate the therapeutic effect of facial artery perforator flap for the soft tissue defects at nose, lip and cheek.
METHODSThe facial artery perforator adjacent to the defect was identified by Doppler ultrasonography. The perforator flap was designed according to the defect location, size and shape. The subcutaneous tissue around the perforator was kept as much as possible to protect the venous drainage.
RESULTSFrom Oct. 2012 to Oct.2013, 26 cases were treated with facial artery perforator flaps, with 9 cases of nasal defects, 10 cases of lip defects and 7 cases of buccal defects. The defects size ranged from 1.5 cm x 2.0 cm to 3.0 cm x 3.0 cm and the flaps size ranged from 2.0 cm x 2.5 cm to 3.5 cm x 3. 5 cm. Superficial necrosis(3mm in width) happened at the end of one flap. All the other 25 flaps survived completely. 16 cases were followed up for 3 months to 2 years with no relapse and satisfactory cosmetic and functional results were achieved.
CONCLUSIONSBoth cosmetic and functional effect can be achieved with facial artery perforator flap for defects at nose, lip and cheek.

Objective To investigate imaging characteristics of multistep hepatocarcinogenesis in cirrhotic livers on susceptibility-weighted imaging (SWI).Methods Seventy-three patients with 83 nodules in cirrhotic livers underwent hepatic MR imaging with SWI.Two radiologists reviewed MR images by consensus.Imaging characteristics of dysplastic nodules (DN),DN with malignant foci and hepatocellular carcinoma (HCC) were evaluated.Prussian blue staining was performed for semiquantification of hepatic iron content and above cirrhosis-associated nodules.Results Positive iron staining of background liver parenchyma was found in 69 of 73 patients and 4 HCC patients showed iron-negative staining of background liver parenchyma.Nine DNs appeared as hypointensity or isointensity with pathologically confirmed similar (n =7) or slightly decreased (n =2) iron deposition compared with background liver parenchyma.SWI detected 14 of 15 DNs with malignant foci.Seven patients appeared as homogeneous hyperintensity and 1 patient appeared as heterogeneous hyperintensity due to intratumoral hemorrhages.The remaining 6 patients demonstrated as nodule-in-nodule appearance with iron deposition in all background nodules,iron deposition with grade 1 in one internal HCC foci,and iron-free in 5 internal HCC foci.The remaining 50 patients with hepatic iron deposition had 55 HCC lesions.Three HCC lesions had iron deposition with grade 1 to 2 and the remaining 52 HCC lesions were pathologically iron-resistant.HCC appeared as hyperintensity compared with siderotic surrounding liver parenchyma.However,HCCs with diameter larger than 3 cm usually demonstrated heterogeneous hyperintensity due to intratumoral hemorrhage.Conclusions SWI could accurately demonstrate dynamic iron depletion on multistep hepatocarcinogenesis in cirrhotic livers.On SWI images,DNs appear as hypointensity due to siderosis and malignant nodules appear as hyperintensity due to iron depletion.

Objective To investigate the value of susceptibility?weighted imaging (SWI) for characterization of small hepatocellular carcinoma (sHCC) in cirrhotic livers. Methods Two hundred seventy?two patients suspiciousof HCC underwent conventional MR imaging and susceptibility?weighted imaging (SWI). Two hundred and five patients were excluded due to either size larger than 3.0 cm, no cirrhosis or HCC. Finally, a total of 84 hepatocellular nodules in 67 patients were included in this prospective study. There were 22 DNs in 12 cases, 8 DNs with HCC foci in 7 cases, and 54 overt HCCs in 48 cases. Two abdominal radiologists independently evaluated signal intensity and enhancing pattern using conventional MRI set and conventional MRI combining with SWI set. A five?point scale was performed to evaluate diagnostic confidence of HCC. Kappa analysis was performed to assess interobserver agreement of the two sets by two readers.The diagnostic performance and confidence level were compared for each image set,ROC was used to evaluate the diagnostic efficiency.Results Good interobserver agreement was identified with a Kappa value of 0.923 for conventional MRI set and 0.865 for conventional MRI combining with SWI set, respectively. The diagnostic sensitivity, specificity, accuracy, and area under the alternative?free response ROC (Az) were 80.6% and 80.6%, 81.8% and 77.3%, 81.0% and 79.8%, 0.804 and 0.782 using conventional MRI set, and 93.5%and 85.5%, 90.9%and 86.4%, 92.9%and 85.7%, 0.898 and 0.859 using conventional MRI combining with SWI set for reader 1 and reader 2, respectively.The diagnostic confidence level of conventional MRI combining with SWI set for diagnosis of HCC with less than 2 cm in size(n=36) was significantly higher than that of conventional MRI (reader 1, 3.86±0.47 vs 3.40±0.91;reader 2, 3.85±0.57 vs 3.41±0.92;t values were 3.733 and 2.468, P were 0.001 and 0.018).Conclusion SWI can provide additional valuable information and improve diagnostic performance for characterization of sHCC in cirrhotic livers.

Objective:To investigate the efficacy of different frequencies of modified electroconvulsive therapy in patients with depressive disorder and its effect on cognitive function and functional near infrared spectroscopy.Methods:The clinical data from 60 patients with depressive disorder, admitted to The Third People's Hospital of Huzhou between December 2022 and July 2023, were retrospectively analyzed. This study was designed as a case-control study. These patients were divided into three treatment groups according to different treatment methods: Group 1 ( n = 20), Group 2 ( n = 20), and Group 3 ( n = 20). All patients underwent conventional antidepressant therapy. Additionally, Group 1 received six sessions of modified electroconvulsive therapy, Group 2 received eight sessions, and Group 3 received ten sessions. The treatment duration for all groups was 4 weeks. Comparisons were made among the three groups for pre- and post-treatment scores on the 24-item Hamilton Depression Rating Scale, 14-item Hamilton Anxiety Rating Scale, Clinical Global Impression Scale, Mini-Mental State Examination, Wisconsin Card Sorting Test, Trail Making Test Part A (TMT-A), Trail Making Test Part B (TMT-B), and Digit Symbol Substitution Test. Furthermore, the incidence of adverse reactions during treatment was calculated, and the Treatment Emergent Symptom Scale was used to assess the occurrence of adverse drug reactions. Moreover, functional Near-Infrared Spectroscopy was used before and after treatment to evaluate the cognitive function of patients under the Verbal Fluency Task. Results:At 1, 2, and 4 weeks of treatment, the 24-item Hamilton Depression Rating Scale, 14-item Hamilton Anxiety Rating Scale, and Clinical Global Impression Scale scores of Group 2 and Group 3 were significantly lower than those of Group 1 ( Finter-group = 32.09, Ftime = 54.27, Finteraction = 7.53, all P < 0.05; Finter-group = 38.14, Ftime = 69.33, Finteraction = 8.59, all P < 0.05; Finter-group = 11.22, Ftime = 28.29, Finteraction = 9.14, all P < 0.05). The Mini-Mental State Examination, Wisconsin Card Sorting Test, and Digit Symbol Substitution Test scores of Group 1 and Group 2 were significantly higher than those of Group 3, while Trail Making Test Part A and Trail Making Test Part B scores of Group 1 and Group 2 were significantly lower than those of Group 3 ( Finter-group = 14.20, Ftime = 44.27, Finteraction = 6.24, all P < 0.05; Finter-group = 18.23, Ftime = 67.15, Finteraction = 8.54, all P < 0.05; Finter-group = 9.30, Ftime = 75.16, Finteraction = 9.41, all P < 0.05; Finter-group = 19.47, Ftime = 85.76, Finteraction = 9.33, all P < 0.05; Finter-group = 22.26, Ftime = 46.37, Finteraction = 6.52, all P < 0.05). There was no significant difference in the incidence of adverse reactions among the three groups ( Finter-group = 3.03, Ftime = 8.36, Finteraction = 1.25, all P > 0.05). After 4 weeks of treatment, the number of Verbal Fluency Task words and oxy-Hb level in Group 2 were significantly higher compared with those in Group 1 and Group 3 ( F = 29.71, 198.57, both P < 0.05). Conclusion:Modified electroconvulsive therapy is highly effective and safe in treating depressive disorders in patients. Eight sessions of modified electroconvulsive therapy administered within 4 weeks have been shown to exhibit better clinical efficacy and lead to greater improvements in cognitive function and functional near-infrared spectroscopy measurements compared with six or ten sessions of treatment.

Objective:To explore the effect of individualized aerobic training combined with resistance training on heart rate recovery and exercise capacity among patients with obstructive sleep apnea syndrome (OSAS) and explore possible mechanisms.Methods:Forty middle-aged patients with moderate to severe OSAS were randomly assigned to an observation group (OG, n=20) or a control group (CG, n=20). Both groups were given routine health guidance and motor training, while the OG additionally underwent individualized aerobic exercise training at 60%~75% of their peak power and resistance training loaded at 60%~80% of their ten-times maximum repetition figure. The training was three times a week for 3 months. Both groups underwent cardiopulmonary exercise testing and polysomnography before and after the 12-week intervention. The changes in their sleep apnea hypopnea index (AHI), oxygen desaturation index (ODI) and lowest oxygen saturation (L-SAO 2) were collected. Exercise capacity indicators such as peak oxygen uptake (VO 2peak), peak power, anaerobic threshold and sitting heart rate recovery (HRR) 1, 2 and 3 minutes after the test were recorded (denoted as HRR-1, HRR-2 and HRR-3). Results:There were no significant differences between the two groups in any of the measurements before the intervention. Afterward the average AHI, ODI and L-SAO 2 values of the observation group had all improved significantly compared with those before the training and compared with the control group′s values after the training. After the training, the VO 2peak and peak power of the observation group had also improved significantly compared with before the training and compared with the control group. HRR-1, HRR-2 and HRR-3 were all significantly higher in the observation group than before the training and higher than the control group′s values after the training. Conclusion:Combining aerobic and resistance training can improve the exercise ability and heart rate of middle-aged patients with moderate to severe OSAS, and also reduce the severity of their OSAS to some extent.
