Conclusion It had the advantage of neuronal protection and nerve regeneration that reparing the injured nerve roots earlv after nerve roots injury.

A strain Actinobacillus succinogenes CGMCC 1593 was selected as the parent strain.After UV-EMS and UV-DES treatments respectively,seven mutated strains with subtle improvements in acid tol-erance were obtained,and were subjected for recursive protoplast fusion.Through three rounds of genome shuffling,four shuffled strains with both higher yield and acid tolerance were obtained.The shuffled strain namely F3-21 could even survive at pH 5.2.The comparison of the shuffled strains and the parent strain for succinic acid production was also studied here.After 48 h of shake-flask fermentation,the succinic acid concentration of F3-21 was 48% higher than that of the parent strain.When F3-21 was carried out in a 5 liter stirred bioreactor with pH controlled 5.6~6.0,the accumulation of succinic acid in 48 h fermentation attained 38.1 g/L,which was increased by 45% compared with that of the parent strain(26.2 g/L).While pH was controlled at 6.5~7.0,the production of succinic acid in 32 h fermentation attained 40.7 g/L.When F3-21 was carried out in fed-batch fermentation,succinic acid concentration of 67.4 g/L was reached in 72 h fer-mentation.These results indicated that the genome shuffling could improve the acid tolerance and the suc-cinic acid production of A.succinogenes CGMCC 1593.

OBJECTIVETo evaluate the clinical results after arthroscopic rotator cuff repair using a suture-bridge technique in late middle-aged adults.

METHODSA retrospective analysis of 30 patients with rotator cuff tears, who were treated consecutively between December 2012 and December 2013 at our clinic, was carried out to evaluate the outcome of arthroscopic suture-bridge technique. The visual analogue scale (VAS), the range of motion (ROM), the rating scale of the University of California at Los Angeles (UCLA), and the shoulder index of the American Shoulder and Elbow Surgeons (ASES) were determined as the evaluation criteria.

RESULTSThe mean follow-up period was 13 months. The follow-up rate was 100%. The study included 0 small, 16 medium, 12 large and 2 massive rotator cuff tears. At the latest follow-up, the VAS score decreased significantly from preoperative 6.3±3.2 to 0.8±1.4 at rest,and from preoperative 7.7±2.1 to 1.7±1.6 during motion. The UCLA score improved significantly from 15.1±4.6 preoperatively to 31.2±5.0 at follow-up. The ASES shoulder index improved significantly from 30.2±16.0 preoperatively to 80.4±13.0 at follow-up. The ROM improved significantly. The satisfactory rate was 94%. There were no complications.

CONCLUSIONThe results of this study indicate that the arthroscopic suture-bridge technique is an effective and reliable treatment for patients with rotator cuff tear in late middle-aged adults.

OBJECTIVETo investigate the relationship between the changes of the copy numbers of mtDNA in peripheral blood mono-nucle- ar cell(PBMC) and the disordered of antioxidant capacity of hepatocellular carcinoma (HCC) patients.

METHODSThe Ficoll Hypaque method was used to isolate the PBMC from blood specimens. The ND1 gene of the mitochondrial was amplified by real-time PCR; meantime β-actin was served as a quantitative standard marker; the difference of mtDNA copy number in PBMC was compared between HCC and healthy control group. The level of reactive oxygen species (ROS) in PBMC was determined by flow cytometry. The change of total antioxidant capacity (T- AOC) of plasma was detected by the biochemistry examination.

RESULTSThe copy numbers of ND1 gene in PBMC of HCC was 73% that of the healthy control group,which suggested a decrease of the copy numbers of mtDNA in HCC. The levels of ROS of PBMC in HCC was (417. 82 ± 110.62) and (301.82 ± 75.54) in control group, which showed that the levels of ROS of PBMC in HCC were significant higher than that in control group (P < 0.01).Plasma T-AOC in HCC was (1.30 ± 0.85), and (3.20 ± 1.62) in control. The T-AOC of plasma of HCC was significantly lower than in control group (P < 0.01).

CONCLUSIONThere was a certain relationship between the decrease of the copy numbers of mtDNA and the disordered antioxidant capacity in hepatocellular carcinoma, which may be associated with the development of hepatocellular carcinoma.

To study the correlation between acute lymphoblastic leukemia (ALL) and HLA-A, B and DRB1 gene in southern Chinese Han population and to investigate the susceptible HLA gene to ALL, a total of 4707 healthy volunteer bone marrow donors from southern Chinese Han population were used as a control group, 201 patients diagnosed as patient group from southern Han individuals were genotyped at HLA-A, B and DRB1 loci by PCR-SSP, PCR-SSOP and SBT. HLA allele frequency and its distribution of ALL patient group were compared with the control group by using chi(2) test, and calculated the statistic value of relative risk (RR), pathogenicity score (EF) and preventive score (PF). The results showed that in comparison with the control group, the gene frequence of HLA-A26, B56 and DR9 increased significantly, but the gene frequence of HLA-A30, A33 and B58 allele frequency decreased significantly for patients with ALL. It is concluded that HLA-A26, B56 and DR9 gene have a high correlation with ALL and seem to contribute the genetic susceptibility to ALL in southern Chinese Han populations. However, HLA-A30, A33 and B58 gene seem to have protective role for southern Han individuals suffered from ALL.

Purpose::To discuss and share the experience of treatment of traumatic innominate arterial injury.Methods::A retrospective analysis was performed on patients with innominate arterial injuries admitted from January 2016 to July 2018 at the department of vascular surgery, Beijing Jishuitan Hospital, China. All the arterial injuries were confirmed by arteriography. Clinical data including mechanism of injury, type of injury, demographics, concomitant injuries, time interval from trauma to blood flow reconstruction, and operation methods were collected. Follow-up program included outpatient visit and duplex-ultrasonography. SPSS version 23.0 was adopted for data analysis. Categorical variables are presented as number and/or frequency and continuous variables as mean ± standard deviation.Result::Altogether 7 patients were included and 6 (85.7%) were male. The mean age of patients was (29.43 ± 7.98) years, range 19-43 years. Six patients had isolated innominate arterial injuries and the rest 1 combined innominate arterial and vein injuries. The injury causes were road accidents in 3 patients, stab wound in 2, gunshot wound in 1, and crush injury in 1. All the 7 patients presented hemorrhagic shock at admission, which was timely and effectively corrected. No perioperative death or technical complications occurred. Intimal injury ( n = 2) and partial transaction ( n = 2) of the innominate artery were treated with covered stents. Two patients with complete transection of artery received vascular reconstruction by artificial grafts. One patient with partial transaction received balloon dilation and open surgical repair (hybrid operation). The mean time interval from trauma to blood flow reconstruction was (4.27 ± 0.18) h, range 4.0-4.5 h; while the operation time was (48.57 ± 19.94) min, range 25-75 min. Cerebral infarction occurred in one patient with brain injury due to anticoagulation contraindication. The average follow-up was (13.29 ± 5.65) months, range 6-24 months. No severe stenosis, occlusion, and thrombosis of covered stents or artificial vessels were found by color Doppler ultrasound. Conclusion::Urgent control of hemorrhage and restoration of blood supply are critical for the treatment of traumatic innominate arterial injury. Endovascular therapy is a feasible and effective method with short operation time and less trauma.

Traumatic peripheral vascular injury is a significant cause of disability and death either in civilian environments or on the battlefield. Penetrating trauma and blunt trauma are the most common forms of vascular injuries. Besides, iatrogenic arterial injury (IAI) is another pattern of vascular trauma. The management of peripheral vascular injuries has been improved in different environments and wars. There are different types of vascular injuries, such as vasospasm, contusion, intimal flaps, intimal disruption or hematoma, external compression, laceration, transection and focal wall defects, etc. The main clinical manifestations of vascular injuries are shock following massive hemorrhage and limb necrosis due to tissue and organ ischemia. Ultrasound, computed tomography angiography (CTA) and magnetic resonance angiography (MRA) are most valuable for assessment of peripheral vascular injuries. Angiography remains the gold standard for diagnosing vascular trauma. Immediate hemorrhage control and rapid restoration of blood flow are the primary goals of vascular trauma treatment. There are many operative treatment methods for vascular injuries, such as vascular suture or ligation, vascular wall repair and vascular reconstruction with blood vessel prostheses or vascular grafts. Embolization, balloon dilation and covered stent implantation are the main endovascular techniques. Surgical operation is still the primary treatment for vascular injuries. Endovascular treatment is a promising alternative, proved to be safe and effective, and preferred selection for patients. In summary, rapid diagnosis and timely surgical intervention remain the mainstays of the treatment. However, many issues need to be resolved by further studies.
