Objective To comparatively analyze Toxoplasma gondii separated from HIV-positive people and RH strain GRA6 gene. Methods By using the nested PCR the amplification of Dali HIV-positive blood samples and RH strains of Toxo-plasma GRA6 genome was performed. The GRA6 gene amplification positive product was selected and the electrophoresis imag-ing was performed by being digested with the Mse I endonuclease and the gene sequences were measured and analyzed. Re-sults The GRA6 gene fragment 800 bp was successfully amplified and about 600 bp and 200 bp bands were got by Mse I. The sequencing results showed that T. gondii GRA6 gene positive samples had 2 nucleotide variation compared with T. gondii strain RH namely 447 base pair at C becoming G and 623 base pair at G becoming T. At 146 bp and 690 bp the Mse I restric-tion sites TTAA were found. Conclusion The preliminary judgment shows that the Dali HIV-positive T. gondii genotype is consistent with RH strain belonging to genotype I.

Objective To investigate the indication of approach,type of fixation and the clinical outcome of minimally invasive internal fixation for treatment of pelvic anterior ring injury.Methods From January 2012 to August 2016,data of 32 patients with 44 pelvic anterior ring injuries who had been treated with minimally invasive internal fixation were retrospectively analyzed.There were 22 males and 10 females with an average age of 38.2 years old (range,20-65 years).14 patients were injured by traffic accident,12 patients by falling and 6 patients by crush injury.There were 4 cases of pubic symphysis diastasis,27 fractures of anterior ring which included 12 billatral fractures and 1 combined vertical displacement of pubic symphysis associated with pubic fracture.According to AO classification,there were 3 cases in A2.3,3 cases in B1.2,4 cases in B2.2,4 cases in B2.3,2cases in C1.1,1 case in C1.2,5 cases in C1.3,4 cases in C2,6 cases in C3.There were 25 patients associated with other injuries,including brain injury in 2,thoracic injury in 17,abdominal injury in 8,urogenital system injury in 5,lumbosacral nerve plexus injury in 4 and the extremity or lumbar fracture in 19.The average period from injury to operation was 9.2 d (range,5-32 d).4 patients who had the pubic symphysis diastasis,3 had pelvic anterior ring fracture medial obturator foramen and 1 combined vertical displacement of pubic symphysis associated with pubic fracture were reduced by modified Pfannenstiel incision and fixed with cannulated screws,while 36 patients with fractures of lateral obturator foramen were reduced by modified Pfannenstiel incision associated with small ilial crest incision and fixed with locking reconstruction plates,and 25 patients received the fixation of pelvic posterior ring injury simultaneously.Results The average time of operation was 44.5 min (range,30-65 min),and the average amount of blood loss intraoperative was 56.2 ml (range,20-150 ml).All patients were followed up successfully,with an average time of 28.2 months (range,16-42 months).All the fractures were healed with an average time of 4.5 months (range,3-9 months).According to Matta standard of reduction assessment,30 fractures' reduction were excellent,12 were good and 2 were fair,which the rate of satisfaction was 95.5％ (42/44).Neither reduction loss or fixation failure nor infection occurred,and the occurrence rate of complication was 9.1％ (4/44),including one patient with fatal liquefaction and was cured 3 weeks after wound dressing,one patient with lateral femoral cutaneous nerve injury who was cured within 3 months by oral drug and 2 patients who complained discomfort of inguinal area because of the fixation prominence and were lessened by physical therapy.Conclusion Minimally invasive internal fixation can be recommended for treatment of pelvic anterior ring injury because of the advantages of less damage,safer manipulation,less complications and good prognosis.

Objective: The aim of this study was to investigate the association of both peripheral and central systolic blood pressure (pSBP and cSBP) with urinary albumin-to-creatinine ratio (UACR) in a community-based population in Beijing. Methods: A total of 3 479 Chinese subjects with questionnaire, UACR, pSBP, and cSBP data available were included from an atherosclerosis cohort of Peking University First Hospital in Shijingshan District, Beijing followed up from April to July in 2014. Multivariate linear regression analyses were used to examine the effect of pSBP and cSBP on lnUACR, and further tests for interactions were performed according to associated covariates. Results: Subjects were (59.0±8.6) years old, 36.2% (n=1 260) were male, 46.0% (n=1 595) had hypertension, and 20.2% (n=700) had diabetes. The pSBP and cSBP was (126.9 ± 16.4) mmHg (1 mmHg=0.133 kPa), and (136.3 ± 16.7) mmHg, respectively. P₅₀ (P₂₅-P₇₅) of UACR was 6.2 (4.2-11.1) mg/g. Both pSBP and cSBP were linearly associated with lnUACR adjusted for age, sex, body mass index, smoking status, drinking status, triglyceride, HDL-C, LDL-C, fasting glucose, creatinine, history of cardiovascular disease, antihypertensive and hypoglycemic agents (every 10 mmHg increase for pSBP: β=0.12, 95%CI: 0.10-0.15, P<0.001; for cSBP: β=0.11, 95%CI: 0.09-0.14, P< 0.001). The relationships were remained in subgroups such as non-hypertension group, non-diabetes group, normal UACR group, and 3-combination group (every 10 mmHg increase for pSBP: β=0.09, 95%CI: 0.05-0.13; β=0.12, 95%CI: 0.10-0.15; β=0.07, 95%CI: 0.06-0.09; β=0.08, 95%CI: 0.05-0.12. for cSBP: β=0.07, 95%CI: 0.04-0.11; β=0.11, 95%CI: 0.08-0.13; β=0.07, 95%CI: 0.05-0.08; β=0.06, 95%CI: 0.03-0.09, all P<0.001). Furthermore, analyses for interaction found that both pSBP and cSBP were more strongly associated with lnUACR in males, current smokers and subjects with high serum creatinine level (≥87 µmol/L) when compared with females, non-current smokers and subjects with low serum creatinine level (<87 µmol/L), respectively (all P for interaction<0.05). Conclusion The results showed that both pSBP and cSBP were independently associated with UACR in this Chinese community-based population even in low risk population suggesting well-controlled both peripheral and central blood pressure may reduce urinary albumin. Males, current smokers and subjects with higher serum creatinine should pay more attention to the impacts of pSBP and cSBP on UACR.

Objective:To investigate the clinical efficacy of MIPO combined with non-contact bridging periprosthesis fracture plate (NCB.PP) in the treatment of re-fracture around the nail after intramedullary fixation of intertrochanteric fracture.Methods:From October 2015 to January 2020, 12 patients with re-fracture around the nail after intramedullary fixation of intertrochanteric fracture were treated in our hospital. There were 7 males and 5 females with an average age of 74.88±12.1 years (range, 65-83 years old); 8 patients on the left side and 4 patients on the right side received short nail of proximal femoral nail (PFN), 6-36 months after operation, they fell down and caused closed fracture around the nail body. According to Vancouver classification system, all the patients were Vancouver type B; preoperative bone mineral density examination showed that 1 case had normal bone mass, 10 cases had osteoporosis, and 1 case had low bone mass. All patients were treated with minimally invasive plate osteosynthesis (MIPO) technique for reduction and fixation, and fixed with proximal femur NCB.PP. The visual analogue scale (VAS) and Harris hip score at 1 day, 3 months and the last follow-up were compared.Results:The average operation time was 68.7±4.33 min (range, 65-75 min); the average intraoperative blood loss was 291.67±114.48 ml (range, 150-400 ml); the average postoperative drainage volume was 79.17±17.17 ml (range, 50-100 ml). After fracture reduction, all patients were able to obtain 2-5 bicortical screws fixation, with an average of 3.25±0.96. Among them, 3 cases were fixed with additional binding straps; 3 cases underwent autologous iliac bone grafting during the operation. All cases were followed up for 9-60 months, with an average of 16 months. At the last follow-up, 10 patients had fracture healing, the healing time was 7.75±2.83 months (range, 4-13 months), and the fracture healing rate was 83.3% (10/12). Among the other two patients, one was an 83 years old patient with severe osteoporosis, who was bedridden after operation and remained unhealed after 12 months of follow-up; a 68 years old patient had bone restoration at the broken end of the fracture 6 months after operation. The second operation was performed. Iliac combined with allogeneic bone graft was taken from the broken end. At the end of 13 months after operation, the fracture was partially healed. The VAS at one week, three months and the last follow-up were 8.00 (8.00, 9.00), 2.50 (2.00, 3.00) and 0.00 (0.00, 0.75), respectively. There were significant differences in VAS scores between 1 week after operation and 3 months after operation, 1 week after operation and the last follow-up, and 3 months after operation and the last follow-up ( Z=-3.129, -3.097, -3.134, all P < 0.05). The Harris scores at 3 months after operation and at the last follow-up were 72.50±2.91 and 86.67±5.30 respectively. After statistical analysis, the difference was statistically significant ( t=8.857, P< 0.001). At the last follow-up, except for 1 case of fracture nonunion and 1 case of reoperation, the Harris score of hip joint of the other 10 patients was excellent in 6 cases and good in 4 cases, and the excellent and good rate was 83.3% (10/12). One case of superficial wound infection was healed by intravenous drip of sensitive antibiotics. One patient had incision fat liquefaction and was given local dressing change to heal the incision. Conclusion:MIPO combined proximal femoral NCB.PP in the treatment of re-fracture around the nail after intramedullary fixation of intertrochanteric fracture has the advantage of less surgical damage, less blood loss, higher healing rate, and it can obtain satisfactory short and medium-term clinical efficacy.

Objective: To explore the treatment outcome of triangular osteosynthesis (TOS) for the treatment of unilateral Isler type II lumbosacral junction injuries (LSJIs). Methods: Data of sixteen patients with unilateral Isler type II LSJIs surgically who were treated in our Hospital from March 2015 to February 2017 were retrospectively analyzed. There were 13 males and 3 females with an average age of 35.5 years (range, 24-61 years). Seven patients were multiple injuries including head, thoracic, musculoskeletal and nerve injuries. According to Isler classification of LSJIs, there were 5 cases of type IIa, 9 of type IIb and 2 of type IIc. All the LSJIs combined with ipsilateral sacral fractures. The sacral fractures were classified by Denis classification with 1 case of zone I, 13 cases of zone II and 2 cases of zone III. According to Tile classification of pelvic fractures, there were 3 cases of type B2, 11 of type C1 and 2 of type C3. There were 3 cases combined with sacral nerve injury among which there were 2 cases of grade II and 1 case of grade III according to Gibbons classification of neurologic deficits. All cases were surgically treated with triangular osteosynthesis. There were 14 cases combined with iliosacral screws fixation in S₁ and 2 cases combined with posterior locking plates. Results: All patients were followed up for 20.6 months (range, 16-30 months). CT scan was conducted 12 to 24 months after surgery which showed all the sacral fractures were union, and 2 cases achieved bony fusion in L₅S₁ facets while the other 14 didn’t. According to Majeed’s pelvic injury evaluation, clinical outcomes were rated with excellent in 12 cases, good in 2 cases, fair in 2 cases. The excellent and good rate was 87.5% (14/16) . According to Mears-Velyvis evaluation criterion, there were 14 cases with anatomical reduction and 2 cases with satisfactory reduction. Among the 3 cases with sacral nerve injury, 2 cases were improved from Gibbons grade II to grade I and the other 1 case was improved from Gibbons grade III to grade II, still feeling numbness on the lateral foot. There were no intraoperative complications in all patients such as neurovascular injuries. No incision infection, fat liquefaction and other incision related complications occurred postoperatively. Irritation and pain in iliac spine about prominent implant occurred in 1 case and lumboscaral stiffness in 1 case, in which the symptom relieved and disappeared after implants removal. Conclusion Triangular osteosynthesis can provide enough stabilization for Isler type II LSJIs and achieve satisfactory outcomes.

Objective To investigate the clinical results and summarize the advantages and surgical indications in the treatment of femoral head fractures (Pipkin type Ⅰ and Ⅱ) via medial hip approach.Methods From October 2014 to August 2015,sixteen patients of femoral head fracture (Pipkin type Ⅰ and Ⅱ) surgically treated via medial hip approach were retrospectively analyzed in our Hospital.There were 13 males and 3 females with an average age of 44.8 years (range,22-62 years old).According to Pipkin classification,12 femoral head fractures were classified as type Ⅰ and 4 type Ⅱ.Thirteen patients were injured by traffic accidents,two patients by falling down from height and one patient was injured by collapses of a heavy objective.All femoral head fractures were combined with posterior hip dislocation.The skeletal traction was performed in each patient after successful close reduction of the hip joint under general anesthesia.Computed Tomography scans of hip joints were performed routinely.All femoral head fractures were fixed with absorbable screws via medial hip approach.The mean time from injury to operation was 5.3 days (range,2-14 days).Results The average duration of the operations was 75 min (range,60-110 min).The average length of incisions was 7.1 cm (range,6-9 cm).The average blood loss was 160 ml (range,80-300 ml).All the patients were followed up for an average period of 26.3 months (range,24 to 30 months).Eight femoral head fractures with Pipkin Ⅰ and three with Pipkin Ⅱ were union and the healing time was 3-12 months,with an average time of 8.8 months.Three femoral head fractures with Pipkin Ⅰ were incomplete union at the latest follow-up of 24 months after surgery.One femoral head fracture with Pipkin Ⅰ and one with Pipkin Ⅱ didn't get union at the latest follow-up of 24 months after surgery.According to Thompson and Epstein function evaluation,the clinical outcomes were rated as excellent in 12 cases,good in 1,fair in 3.The excellent and good rate was 81.3％ (13/16).According to Merled'Aubigne-Postel evaluation criterion,there were 13 cases excellent,1 good and 2 fair.The excellent and good rate was 87.5％ (14/16).There were no intraoperative complications in all patients such as neurovascular injury injuries.No incision infection,fat liquefaction and other incision related complications occurred postoperatively.Avascular necrosis of the affected femoral head occurred in one case whose symptom didn't aggravate after appropriate conservation.Fractures were nonunion in 2 cases but the patients' functions were satisfactory in daily living.Traumatic arthritis of the affected hip occurred in 2 cases.The patients felt uncomfortable with long walking but could get better after taking NSAIDs.The fracture fragment absorption occurred in 3 cases but these patients had a good function and needed no further treatment.Conclusion Good exposure could be achieved for reduction and fixation in the treatment of femoral head fractures (Pipkin Ⅰ、Ⅱ) via hip medial approach.The operation is a minimally invasive procedure and the treatment outcome is satisfactory,but the indication should be strictly controlled.
