Objective: To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality. Methods : The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model. Results: Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death. Conclusions The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.

OBJECTIVE: To investigate the clinical value of sentinel lymph node (SLN) detection in laryngeal and hypopharyngeal carcinoma patients with clinically negative neck (cN0) by methylene blue method, radiolabeled tracer method and combination of these two methods. METHOD: Thirty-three patients with cN0 laryngeal carcinoma and six patients with cN0 hypopharyngeal carcinoma underwent SLN detection using both of methylene blue and radiolabeled tracer method. All these patients were accepted received the injection of radioactive isotope 99 Tc(m)-sulfur colloid (SC) and methylene blue into the carcinoma before surgery, then all these patients underwent intraopertive lymphatic mapping with a handheld gamma-detecting probe and blue-dyed SLN. After the mapping of SLN, selected neck dissections and tumor resections were peformed. The results of SLN detection by radiolabeled tracer, dye and combination of both methods were compared. RESULT: The detection rate of SLN by radiolabeled tracer, methylene blue and combined method were 89.7%, 79.5%, 92.3% respectively. The number of detected SLN was significantly different between radiolabeled tracer method and combined method, and also between methylene blue method and combined method. The detection rate of methylene blue and radiolabeled tracer method were significantly different from combined method (P < 0.05). Nine patients were found to have lymph node metastasis by final pathological examination. The accuracy and negative rate of SLN detection of the combined method were 97.2% and 11.1%. CONCLUSION The combined method using radiolabeled tracer and methylene blue can improve the detection rate and accuracy of sentinel lymph node detection. Furthermore, sentinel lymph node detection can accurately represent the cervical lymph node status in cN0 laryngeal and hypopharyngeal carcinoma.

Objective To compare the dinical outcome of posterior Gallie method with cable fixation and Harms technique with C1,2 pedicle screw fixation in treatment of odontoid fractures. Methods From July 2003 to July 2008, 26 patients with types Ⅱ and Ⅲ odontoid fractures were treated surgically. There were 18 males and 8 femalses, at age range of 22-65 years ( average 43 years). The patients were divided into Gallie titanium cable fixation group (Gallie group, n = 14) and C1 -C2 posterior screw fixation group using Harms technique (Harms group, n = 12) according to treatment methods to compare blood loss, operation duration, costs, hospital stay, bone fusion time, complications and secondary operation. Results The patients were followed up for 18-84 months ( average 37.3 months). The average blood loss and costs in Gallie group were significantly less than that in Harms group (P<0.05), while the time for back to work in Gallie group was significantly longer than that in Harms group ( P < 0. 05 ). There was no statistical difference upon operation duration, hospital stay and bone fusion time in two groups (P > 0. 05 ). There was one patient with nonunion and two with delayed union in Gallie group and one with secondary operation due to implant failure in Gallie group, and one with secondary debridement due to wound infection and one with delayed wound healing in Harms group, with no statistical difference (P > 0. 05). Conclusions Both Gallie technique with titanium cable fixation and Harms C1,2 screw fixation have advantages of early walk and short hospital stay. Compared with the former, the latter technique costs more but can help early back to work.

Objectives To evaluate final adult height(FAH), lipid profile, sexual development, and quality of life in individuals with childhood-onset growth hormone deficiency (CO-GHD) during the transition from childhood to adulthood, to reassess the function of GH-IGF-I axis, and to explore effective managements for different types of GHD in each period. Methods Totally 80 CO-GHD patients were divided into 2 groups; 22 patients with isolated growth hormone deficiency ( IGHD) and 58 patients with multiple pituitary hormone deficiencies (MPHD); 62 male (age ≥18 years) and 18 female ( age ≥ 16 years) patients. The clinical and biochemical parameters, education and occupation, rhGH, and other hormones therapy in the past were followed up. Results rhGH replacement improved FAH of patients with GHD. The incidences of either hyperlipidemia (39.0% , 47.4%) or fatty liver disease (26.8%, 31.6%) showed no statistically significant changes between 2 groups with and without rhGH replacement. Mean value of IGF-I SDS was significantly higher in IGHD group than that in MPHD group (-1.43±0. 31,-3. 01 ±0. 66) ,and also IGFBP3(-2. 10±0. 33,-3. 17±0. 19,all P< 0.05 ). Patients with IGHD had normal sexual development, but the incidence of sexual dysfunction accounted for 79.7% in MPHD group. Conclusions rhGH improves FAH of individuals with CO-GHD. Patients with CO-GHD should be followed during the transition period; GHD patients carry a high risk of metabolic abnormalities in the adulthood; IGHD female can give birth to offsprings; patients with MPHD have gonadotrophin deficiency of varying degrees.

Objective To explore the value of amino-terminal propeptide of C-type natriuretic peptide (NTproCNP) in evaluating the efficacy of therapy with recombinant human growth hormone ( rhGH ) in patients with idiopathic short stature (ISS) and isolated growth hormone deficiency ( IGHD ).Methods Forty-eight prepubertal children( IGHD n=25,ISS n=23 ) treated for at least 1 year with rhGH were included.Serum insulin-like growth factor- Ⅰ ( IGF- Ⅰ ) and NTproCNP levels were measured before starting treatment and 6 months later.Twelve months after starting treatment,all patients were assessed and annual growth velocity ( GV ),height standard deviation score ( HTSDS),and gained HTSDS (△HTSDS) were recorded.Results In GHD group,positive relationships between GV and change of IGF- ISDS( △IGF- ISDS ),GV and change of NTproCNP concentrations(△NTproCNP) were found( r=0.407,P=0.044 ;r=0.490,P=0.013 ).GH peak value was also positively associated with IGF- ISDS and NTproCNP before therapy ( r =0.558,P =0.004; r =0.630,P =0.001 ).△IGF- ISDS and △NTproCNP were positively associated after therapy ( r =0.466,P =0.019 ).In ISS group,GV was associated with △NTproCNP ( r=0.845,P＜ 0.01 ).Conclusions NTproCNP is a novel biomarker of growth as its level increases during growth-promoting treatment.Furthermore,IGF- Ⅰ is also valuable in evaluating the efficacy of rhGH therapy in short stature patients.

Objective To investigate the clinical characteristics and molecular pathological mechanism of McCune-Albright syndrome ( MAS) in order to provide a guidance for the precision medicine of MAS. Method The clinical data and genetic findings of 41 patients with MAS were analyzed retrospectively. Results (1) MAS girls had the phenotype of peripheral precocious puberty with premature sexual development and high estradiol, low LH and FSH, and the increased volume of uterus and ovary. ( 2 ) In 41 MAS cases, there were 17 cases with GNAS1 gene mutation, and the total positive rate was 41. 5%, of which the classic triad was 66. 7%, two signs 56. 3%, and 12. 5% in only one classic sign. GNAS1 gene mutation was found in 78. 6% of patients with polyostotic fibrous dysplasia of bone, while only 55. 0% in patients with cafe au lait skin spots. Children with precocious puberty and fibrous dysplasia of bone is an important basis for clinical diagnosis of MAS, but cafe au lait skin spots does not seem to be the specifical manifestation of MAS. Conclusion Clinically MAS was lack of typical clinical manifestations, and the most important clinical weight factor for the diagnosis of MAS was peripheral precocious puberty with fibrous dysplasia of bone. GNAS1 gene screening may be helpful to improve the clinical accurate diagnosis of MAS.

OBJECTIVETo determine the outcome of combined anterior C2,3 reduction and fusion with posterior compressive C2 pedicle screw fixation for the management of unstable Hangman's fractures.

METHODSSixteen cases of unstable Hangman's fractures were retrospectively reviewed through X-ray, MRI and three dimensional CT scans. Pre- and postoperative radiographs were measured for translation and angulation of C2,3. Skull traction under extension poison was conducted in all the patients right after their admission. Then anterior C2,3 discectomy followed by interbody fusion, either with iliac autograft or with box cage, and locking plate fixation were performed in each case. Because dissatisfied reduction, mainly residual large fracture gap or kyphosis, was found by the C-arm fluoroscopy during operations, posterior compressive C2 pedicle screw fixation was performed in one stage. According to the Levine-Edwards classification, there were 12 cases of type II, 2 of type I a and 2 of type III in this group.

RESULTSFollow-up ranged 6-38 months, averaged 26 months. Fracture union and bone graft fusion were completed in an average of 4 months after operation. Complaints of neck pain and numbness of limbs disappeared in all patients after surgery, but range of neck motion decreased compared with normal people. Translation of C2 decreased from (4.2 +/- 1.4) mm preoperatively to (2.3 +/- 1.1) mm postoperatively, while angulation of C2,3 decreased from 8.6 degrees +/- 2.1 degrees preoperatively to 2.6 degrees +/- 1.0 degrees postoperatively. Both have statistical significance (P < 0.05). No implant failure or infection was observed.

CONCLUSIONSThe classification of Hangman's fracture should be modified in combination with MRI and CT scans to determine the stability of the fracture. Combined anterior C2,3 reduction and fusion with posterior compressive C2 pedicle screw fixation is the treatment of choice for patients with unstable Hangman's fractures.
