Objective To investigate the imaging findings of the lacerating injury of the lung. Methods Ten patients of lung lacerating injury were examined by X-ray and CT within 1—5 h after injury. X-ray(2—5 times)and CT(3—5 times)examinations were repeated for 7 patients.Results The lung lacerating injury involved 10 sides and 14 lung lobes(21 lesions in total)in the 10 cases,among which 1 case involved the right upper lobe with 1 lesion,2 cases in the right lower lobe with 2 lesions,1 case in the right upper and lower lobes with 2 lesions for each lobe,3 cases in the left lower lobe with 9 lesions,and 3 cases in both the left upper and the lower lobes with 7 lesions.The X-ray findings were cavity-like shadows with smooth margin in 9 lesions(9/21),and patchy shadows of fogging margin in 12 lesions(12/21).The CT imaging findings included 6 pulmonary hematomas(6/21),and 15 cavitary lesions with air-fluid levels (15/21).In the 15 cavitary lesions,CT revealed 14 single cavities and 2 small cavities within a big cavity. On dynamic follow-up observation,the cavity was the biggest in 1—5 h after injury,but the hematoma was the biggest in 2—3 days after injury.Hematomas tended to absorb slower than the cavities.After 16— 32 days,all lesions revolved into small patchy or stripe-like shadows with slightly increased density. Conclusion Cavitary lesion with air-fluid level is the characteristic imaging finding of lung lacerating injury.CT surpasses X-ray plain film in revealing the details of lung lacerating injury.

OBJECTIVETo investigate the curative effect of arthroscopic glenoid labrum repair by biodegradable anchor fixation for recurrent anterior shoulder dislocation.

METHODSTwenty-one patients of recurrent anterior shoulder dislocation with the average UCLA function score of 22.3 ± 4.1 were treated with arthroscopic glenoid labrum repair by biodegradable anchor fixation. The shoulder was fixed by shoulder-elbow elastic band for 4-6 weeks and canonical exercise of shoulder joint was taken postoperatively.

RESULTSThe patients were followed up for 3-18(mean 8) months; and the average UCLA score was 32.3 ± 2.6 postoperatively. The excellent results (34-35) were obtained in 11 patients, good (28-33) in 7 patients and fair (21-27) in 3 patients. The activity of shoulder joint was normal in all patients with an excellent subjective degree of satisfaction.

CONCLUSIONArthroscopic glenoid labrum repair by anchor fixation for recurrent anterior shoulder dislocation has the advantages of less invasiveness, simpler procedure, reliable fixation, less complications and rapid functional recovery.

BACKGROUND: Vibrio vulnificus inside the body could activate the NF-κB signaling pathway and initiate the inflammatory cascade. The lung is one of the earliest organs affected by sepsis associated with acute lung injury. High mobility group protein B1 (HMGB1) is an important late-acting pro-inflammatory cytokine involving in the pathophysiology of sepsis. It is also involved in the injury process in the lung, liver and intestine. There has been no report on the involvement of HMGB1 in Vibrio vulnificus sepsis-induced lung injury. METHODS: Sixty rats were randomly divided into a normal control group (group A,n=10) and a Vibrio vulnificus sepsis group (group B,n=50). Sepsis was induced in the rats by subcutaneous injection of Vibrio vulnificus (concentration 6×108 cfu/mL, volume 0.1 mL/100g)) into the left lower limbs. The rats in group B were sacrificed separately 1, 6, 12, 24, and 48 hours after the infection. Their lungs were stored as specimens, lung water content was measured, and lung pathology was observed under a light microscope. The expressions of the HMGB1 gene and protein in the lungs were detected by RT-PCR and Western blot. Data were analyzed with one-way analysis of variance (ANOVA) and the LSD method for pair-wise comparison between the two groups.P<0.05 was considered statistically significant. RESULTS: Compared to group A (0.652±0.177), HMGB1 mRNA expression in the lungs of group B was significantly higher at 0 hour (1.161±0.358,P=0.013), 24 hours (1.679±0.235,P=0.000), and 48 hours (1.258±0.274,P=0.004) (P<0.05), and peaked at 24 hours. Compared to group A (0.594±0.190), HMGB1 protein expression at 6 hours (1.408±0.567,P=0.026) after infection was significantly increased (P<0. 05), and peaked at 24 hours (2.415±1.064,P=0.000) after infection. Compared to group A (0.699±0.054), lung water content was significantly increased at 6 hours (0.759±0.030,P=0.001),12 hours (0.767±0.023,P=0.000), 24 hours (0.771±0.043,P=0.000) and 48 hours (0.789±0.137,P=0.000) after infection (P<0.05). Compared to group A, pathological changes at 12 hours in group B indicate marked pulmonary vascular congestion, interstitial edema and inflammatory infiltration. Alveolar cavity collapse and boundaries of the alveolar septum could not be clearly identified. CONCLUSION:Vibrio vulnificus sepsis can lead to injury in rat lungs, and increased HMGB1 expression in lung tissue may be one of the mechanisms for injury from Vibrio vulnificus sepsis.

To investigate the resources of medicinal plant, such as wild Apocynum, supervised classification based on Principal Component Analysis (PCA) and texture feature were used to monitor wild medicinal plants from image captured by ZY-3 and World-view-2 and compare which satellite Image are more appropriate to monitor the wild medicinal plants. The research results shows that: for more complex growth conditions wild medicinal plants Apocynum, high-resolution images Worldview-2 is more suitable for its remote identification, the low-resolution satellite ZY-3 can only recognizes the wild medicinal plants which distributed intensively. If the study target distribution is more intensive and larger scale, and cultivated type medicinal plants, the use of satellite ZY-3 in low resolution remote sensing data to identify the target can be a good choice, it is not necessary to buy high-resolution data, in order to avoid waste of expenditure, for the scattered distribution, the high-resolution satellite imagery data may be indispensable to identify targets.

OBJECTIVETo assess the association between leptin gene promoter methylation and serum leptin concentrations in patients with impaired glucose regulation (IGR) and type 2 diabetes mellitus (T2DM).

METHODSMethylation status of leptin gene promoter was determined with methylation-specific polymerase chain reaction. Serum leptin concentrations were determined using enzyme-linked immunosorbent assay.

RESULTSAmong three groups of individuals with different levels of glucose, the methylation rates of leptin gene in IGR and T2DM groups were 43.6 % and 31.5 %, respectively, which were significantly lower than that of healthy subjects (59.2%; Chi-square=22.499 and 5.109, respectively, P<0.05). A lower methylation rate was also observed in T2DM group compared with IGR group (Chi-square=3.962, P<0.05). Leptin levels in both T2DM and IGR groups were elevated compared with normoglycemic subjects, but only T2DM group was significantly higher (q=6.81, P<0.01). Linear regression analysis indicated that serum leptin concentrations has increased along with declining of DNA methylation rate (r=-0.95, P<0.01).

CONCLUSIONLower levels of leptin gene promoter DNA methylation and serum leptin concentrations are associated with the development of diabetes. Measurement of the methylation status of leptin gene promoter and expression can facilitate early intervention of the disease.

OBJECTIVETo investigate the telomerase activity of human adipose derived stem cells (ADSCs) during proliferation and differentiation in vitro.

METHODSADSCs were highly purified and cultured in vitro. The morphology, phenotype and biological properties of the cultured ADSCs were observed by flow cytometer. Then ADSCs were induced to differentiate into adipocytes and osteoblast. The telomerase activity was detected by TRAP.

RESULTSADSCs had the ability of multi-directed differentiation, like adipocytes and osteoblast. It could also express the stem cell-related surface markers. The telomerase activity was negative or lowly expressed in ADSCs in vitro within 12 generations. The telomerase activity was up-regulated when ADSCs was adipogenic differentiated, but deceased 3-6 days later.

CONCLUSIONSThe telomerase activity of ADSCs is not changed during culture in vitro. It is up-regulated when ADSCs are induced to adipogenic differentiation, but decreased later.

OBJECTIVETo discuss the causes of unsatisfied cervical posterior decompression surgery and describe the overhauling strategies and precaution.

METHODSThe clinical data of 14 patients required revision surgery were retrospectively analyzed, and these patients with unsatisfied effects were due to cervical posterior decompression surgery from January 2012 to December 2014. Overhauling reasons were analyzed and then different revision procedures were performed. The functions of cervical cord and ambulation were evaluated respectively by modified Japanese Orthopedic Association(mJOA) score and Nurick grade according to the course order:preoperative for the first time, pre-revision and at final follow-up. Improvement rate of nerves function were calculated before and after operation for the first time, before and after revision. Above data were statistically analyzed by SPSS16.0 software.

RESULTSReoperation reasons including 2 patients with the insufficiency width of laminectomy, 2 patients with the inadequate length of decompression, 2 patients with nerve root and spinal cord compression caused by fractured collapse, 4 patients with closed the door of vertebral lamina, 1 patient with less open-door angle, 2 patiens with ossification of posterior longitudinal ligament (1 case complicated with close the door), 2 patients with cervical spine kyphotic deformity aggravating (1 case complicated with close the door), 1 patient with nerve root canal stenosis caused by uncovertebral joint hyperplasia. Preoperative for the first time, pre-revision and at final follow-up, mJOA scores were 11.89±1.67, 13.11±1.09, 15.61±0.59, and Nurick grades were 4.21±0.58, 3.57±0.51, 1.71±0.47, respectively. There was significant difference between final follow-up and preoperative for the first time, pre-revision(<0.05). Improvement rate of nerve function was (22.33±9.49)% with bad before and after operation for the first time, and (64.60±9.88)% with good before and after revision, with statistical significance(<0.05).

CONCLUSIONSIndividualized revision surgery based on different causes for unsatisfied cervical posterior decompression can improve the function of spinal cord. Preoperative carefully analyzing the etiological factors, thoroughly decompression can reduce the revision rate.
