Abstract：Objective To investigate the detection methods of newly discovered leprosy cases in Hunan Province in 2013-2022, and analyze the trend of changes, and provide scientific basis for the prevention and treatment of leprosy. Methods The detailed information of newly diagnosed leprosy cases in Hunan Province from 2013 to 2022 was collected through the Leprosy Management Information System (LEPMIS), and the descriptive epidemiological method was used to analyze the detection methods of newly discovered leprosy cases. Results From 2013 to 2022, a total of 250 newly diagnosed leprosy cases were detected in Hunan Province, including 143 cases (57.20%) were found in outpatient clinics, 33 cases (13.20%) were found in clue investigations, 27 cases (10.80%) were notifiable-reported, 23 cases (9.20%) were self-reported, 11 cases (4.40%) were found in other ways (e.g., group survey), 9 cases (3.60%) were found in contact examinations, 2 cases (0.80%) were found in census, and 2 cases (0.80%) were found in epidemic point inspection. From 2013 to 2022, the number of cases detected in outpatient clinics showed an upward trend (rs=0.515), while the cases detected in clue investigation (rs=-0.873), notifiable-reported (rs=-0.127), self-reported (rs=-0.301), contact examination (rs=-0.363), census (rs=-0.701) and epidemic point inspection (rs=-0.701) showed a downward trend. The majority of leprosy cases with different demography characteristics and clinical characteristics were found through outpatient clinics, except that the majority of leprosy cases in children were found by contact examination (66.76%). Of 165 male cases, 92 cases (55.76%) were found in outpatient clinics and 51 out of 85 female cases (60.00%) were found in outpatient clinics. Among age groups, 113 out of 187 cases aged 15 to 60 (60.43%) and 30 out of 60 cases aged over 60 (50.00%) were found in outpatient clinics. Among patients with differentoccupations, 112 out of 208 cases of farmers (53.85%) and 31 out of 42 cases of other occupations (73.81%) were found inoutpatient clinics. Among cases with different types of leprosy, 111 out of 185 cases of multibacillary leprosy (60.00%) and 32 out of 65 cases of paucibacillary leprosy (49.23%) were found in outpatient clinics. Among cases with different numbers of skin lesions, 4 out of 8 cases of skin lesion-free leprosy (50.00%), 3 out of 9 cases of single skin lesion leprosy (33.33%), and 136 out of 233 cases of multiple skin lesions leprosy (58.37%) were found in outpatient clinics. Of 72 cases without nerve damage, 48 cases (66.67%) were found in outpatient clinics. Of 27 cases with single nerve damage, 17 cases (62.96%) were found in outpatient clinics. Of 151 cases with multiple nerve damage, 78 cases (51.66%) were found in outpatient clinics. Among patients with different levels of malformation, 58 out of 102 cases with no malformation (56.86%), 28 out of 45 cases with Grade malformation (62.22%), 35 out of 68 cases with Grade Ⅱmalformation (51.47%), and 22 out of 35 cases with other types of malformation (62.86%) were found in outpatient clinics. Conclusions Outpatient clinics is the main way to detect newlydiagnosed leprosy cases under the low prevalence of leprosy in Hunan Province, and it is an important strategy to move the early detection of leprosy cases to comprehensive medical institutions in the future.

Objective To investigate the MRI features of spinal epidural angiolipomas.Methods Clinical and MRI data of 18 patients with spinal epidural angiolipomas confirmed pathologically were retrospective analyzed.The MRI features of lesion site,size,shape,signal,bone destruction,enhancement and typing were observed and analyzed.Results One case of 18 cases were located in cervical vertebra,15 cases were thoracic vertebra,and 2 cases were lumbar vertebra.Ten cases formed paravertebral lump through foramen intervertebrale and damaged adjacent bones.MRI showed that T1W1 signal intensity was either isointense (n 11),mixed intense (n=5) or hyperintense (n =2).T2WI showed signal intensity was hyperintense (n=13) or mixed intense (n=5).The fat signal was seen in 5 cases,both T1W1 and T2W1 showed hyperintense.All the 18 cases showed remarkable enhancement.Ⅰ type (lesions confined to the spinal canal) was 8 cases (8/18,44.44％),Ⅱ type (lesions were dumbbell-shaped to the spinal canal) was 10 cases (10/18,55.56％).Conclusion The location of occurrence and the manifestations of MRI in spinal epidural angiolipomas have certain characteristics,which provides important clues to the preoperative diagnosis.

Objective To discuss the value of hypotonic-MRCP combined with LAVA dynamic contrast-enhanced scan in diagnosis of duodenal tumor.Methods Five patients with duodenal adenocarcinomas confirmed by pathology were involved in this study.All cases underwent plain MRI and hypotonic-MRCP and LAVA dynamic contrast-enhanced scans.Results 4 of 5 cases were correctly diagnosed with MR imaging.Imaging signs included:the cavum of descending duodenum appeared as asymmetrical stenosis,masses with soft tissue signal intensity connecting the intestinal wall with wide base,the intestinal wall stiff,the intestinal mucosa destruction.The lesions would be slightly-moderately enhanced at LAVA dynamic enhancement scanning.Conclusion Hypotonic-MRCP combined with LAVA dynamic contrast-enhanced scan can display the direct and indirect sign of duodenal tumors,which was effective in identifying the circumscription of the tumor and its extension.

Background and purpose:Early evaluating the therapeutic efficacy of transcatheter arterial chemoembolization (TACE) in patients with hepatic cancer is still a diffcult clinical problem. The purpose of this study was to evaluate the ability of the apparent diffusion coeffcient (ADC) to help predict early disease progression after TACE.Methods:Institutional review board approval was obtained, and all patients signed informed consent. Magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) (b=50, 500, 1 000 mm2/s) were performed before and 1 month after initiating TACE for 23 patients with hepatic cancer (14 were male, 9 were female; mean age: 53.3 years;range: 21-85 years). Contrast-enhanced MRI was performed 3 months after initiating TACE. Patients were classiifed as either progressing or non-progressing according to RECIST 1.1. The preoperative ADC values of tumor and the ADC values of tumor 1 month after TACE were analyzed by pairedt-test in both progressing and non-progressing group. Unpairedt-test was used to compare ADC parameters between progressing and non-progressing group. In all the 23 hepatic cancer patients, receiver operating characteristic (ROC) curve analysis was performed to determine a threshold ADC ratio (ADC%) to differentiate progressing from non-progressing patients.Results:Thirteen progressing and 9 non-progressing patients were evaluated. Increase in ADCs of tumor was observed in non-progressing patients at 1 month after TACE compared with preoperative ADCs. There was a signiifcant difference between the 2 groups (P=0.01). In progressing group, preoperative ADCs of tumor were similar to those at 1 month after TACE (P=0.221). There was no significant difference in preoperative ADCs of tumor and ADC% between the progressing and non-progressing groups. In patients with hepatic cancer, 1 month ADC ratio in non-progressing patients were signiifcantly higher than those of progressing patients (P=0.029). Using ROC to evaluate the ability of ADC% could predict early disease pro-gression after TACE. Using -6.455% as the threshold, the area under the ROC curve was 0.867 (95%CI: 0.643-1.000). The sensitivity was 100%, and the speciifcity was 66.7%.Conclusion:One month after TACE, the increases in ADCs of tumor were observed only in the non-progressing group; and the ADC ratio seems to be a promising tool for helping predict the early disease progression after TACE in patients with hepatic cancer.

Objective To observe the effect of acupoint thread-embedding at Neiguan (PC6) and Zusanli (ST36) on anxiety and sleep disorders after heroin withdrawal. Method Sixty-seven patients with heroin addiction were randomized into a Neiguan group (25 cases), a Zusanli group (22 cases) and a Neiguan plus Zusanli group (20 cases), to receive corresponding treatments once every 20 d, for 4 sessions in total. The Self-rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI) were adopted to observe the anxiety and sleep condition before and after the treatment. Result After 60 d thread-embedding treatment, the total and standard SAS scores, sleep initiation time and total PSQI score were significantly decreased in the 3 groups (P<0.05), and the sleep durations were significantly extended (P<0.05); in comparing the improvement of anxiety, Neiguan plus Zusanli group > Neiguan group >Zusanli group (P<0.05); in comparing the improvement of sleep, Neiguan plus Zusanli group was superior to both Zusanli group and Neiguan group (P<0.05), while there was no significant difference between Zusanli group and Neiguan group (P>0.05). Conclusion It's effective to use thread-embedding at Neiguan and Zusanli independently or together for anxiety and sleep disorders after heroin withdrawal, but the efficacy is more significant when the two points are used in combination, indicating the synergy of acupoints.
