ABSTRACT
OBJECTIVE@#To evaluate the efficacy and prognosis of double button plate combined with strengthened anchor technique and clavicular hook plate internal fixation for complete acromioclavicular joint dislocation.@*METHODS@#From July 2017 to September 2020, a total of 42 patients with acromioclavicular joint dislocation treated by surgery were choosen as study objects and divided into observation group (21 cases) and control group (21 cases). In the observation group, there were 14 males and 7 females, aged 21 to 63 years old, with an average of (45.05±8.70) years old. In the control group, there were 16 males and 5 females, aged 25 to 68 years old, with an average of(45.00±9.44) years old. The patients in the observation group were treated with double button plate combined with strengthened anchor technique, whereas those in the control group received clavicular hook plate internal fixation. The two groups were compared in terms of operating time, intraoperative blood loss, postoperative hospital stay, shoulder pain(visual analogue scale, VAS) score, shoulder function Constant-Murley score and postoperative complications.@*RESULTS@#There was no significant difference between the two groups in intraoperative blood loss or postoperative hospital stay(P>0.05). The operating time of double button plate combined with strengthened anchor technique group (65.24±5.36) min was significantly longer than that of the clavicular hook plate group (48.81±4.72) min, and the difference was statistically significant (P<0.05). There was no significant difference in shoulder function or pain degree between the two groups before operation (P>0.05). After 1 month, 3 months and 6 months, the Constant-Murley score of the observation group was 73.29±2.15, 85.43±1.47, 93.86±1.24 separately, which were significantly higher than those of the control group;and the VAS score was 2.76±0.62, 1.71±0.64, 0.57±0.51 separately, which were significantly lower than those of the control group (P<0.05). One instance of shoulder discomfort was found in the observation group, while 5 cases of shoulder pain, 2 cases of restricted shoulder mobility, and 1 case of subacromial bone absorption were found in the control group. In both group, there was no loss of reduction.@*CONCLUSION@#In the treatment of complete acromioclavicular joint dislocation double button plate combined with strengthened anchor technique achieves favorable clinical result. Internal fixation does not need to be removed. The recovery of shoulder joint function and pain relief are superior than clavicular hook plate internal fixation, which is more worthy of clinical promotion.

<p><b>OBJECTIVE</b>To study the clinical characteristics and laboratory results of 24 confirmed H1N1 influenza cases.</p><p><b>METHODS</b>The characters of clinical, laboratory, iconography and etiology of 24 patients with A/H1N1 were studied, and the changes of T-lymphocyte subsets that between the pre- and post-treatment were evaluated.</p><p><b>RESULTS</b>The ages of patients were ranged from 6 to 65 years old; average age was 26 years old.15 patients were under 25 years old. 22 (22/24, 91.7%) patients had recently traveled to USA or Canada. The most common presenting symptoms were: fever (22/24, 91.7%); sore throat (22/24, 91.7%); cough (20/24, 83.3%); dry cough (14/24, 58.3%); expectoration (6/24, 25.0%); nasal discharge (6/24, 25.0%). Six had pneumonia in sixteen patients (6/16, 37.5%) who took CT scan; seven (7/24, 29.2%) had headache and four (4/24, 16.7%) had muscular soreness; two (2/24, 8.3%) had sneeze and nasal obstruction; only one(1/24, 4.2%) had diarrhea; one (1/24, 4.2%) had conjunctivitis. The result of 23 patients about T-Lymphocyte subsets: most of CD4 and CD8 were decreased (18/23, 78.3%), ranging from 122 to 691 cells/microl (normal was 706 - 1125 cells/microl), with the average of 408 cells/microl, but ratios of CD4/CD8 were normal. Fourteen patients were detected CD4 and CD8 after received the treatment during 5 to 7 days.the results of CD4 (cells/microl) were different between the pre- and post-treatment: 436.29 +/- 189.06, 976.71 +/- 332.96 (paired-samples t test: t = -5.416, P < 0.05) while the results of CD8 (cells/microl) were: 323.64 +/- 176.47, 703.14 +/- 211.77 (t = -5.319, P < 0.05); the results of leukocytes in 22 patients were different between pre- and post-treatment: (5.13 +/- 1.47) x 10(9)/L, (6.25 +/- 1.37) x 10(9)/L (t = -2.900, P < 0.05) while the results of lymphocytes were: (1.16 +/- 0.43) x 10(9)/L, (2.30 +/- 0.37) x 10(9)/L (t = -6.819, P < 0.05); but the ratios of CD4/CD8 were: 1.44 +/- 0.41, 1.40 +/- 0.26 (t = 0.507, P > 0.05). All the patients were received antivirus treatment (Oseltamivir) and the virus conversed during 1 - 10 days (average 4.5 days). The temperature was normal after onset during 3 - 4 days and the patients were recovered during 3 - 13 days (with the average of 7.3 days).</p><p><b>CONCLUSION</b>Influenza A virus H1N1 subtype was identified as the cause of outbreaks of febrile respiratory infection which was self-limited. There was no evidence to show that the changes of T-Lymphocyte subsets could indicate the prognosis of patients.</p>
