OBJECTIVETo perform a meta-analysis on clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults.

METHODSPubmed database (from 1968 to March 2014), Cochrane library and CNKI database (from 1998 to March 2014) were searched. Case-control study on minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults were chosen,and postoperative infection, operative time, blood loss, fracture nonunion rate, delayed union,fracture malunion rate were seen as evaluation index for meta analysis. The system review was performed using the method recommended by the Cochrane Collaboration.

RESULTSTotally 5 studies (366 patients) were enrolled. Meta-analysis showed that there were significant meaning in postoperative infection between MIPPO and ORIF [OR = 0.23,95% CI (0.06,0.92), P = 0.04]; fracture nonunion rate in MIPPO was lower than in ORIF group [OR = 0.16, 95% CI (0.03,0.76), P = 0.02]; operative time in MIPPO was shorter than in ORIF group, and had significant difference [MD = -14.42, 95% CI (-27.79, -1.05), P < 0.05]; blood loss in MIPPO was less than in ORIF group [MD= -87.17,95%CI (-99.20, -75.15), P < 0.05]; there was no obviously meaning in delayed union between two groups.

CONCLUSIONFor distal tibial fractures in adults, MIPPO has, advantages of short operative time, less blood loss, lower incidence of infection and fracture non-uniom, but with high fracture malunion rate. MIPPO for distal tibial fractures in adults is better than ORIF, and the best treatment should choose according to patient's condition.

OBJECTIVETo evaluate the results of the surgical treatment of patients with Budd-Chiari syndrome (BCS).

METHODSThe clinic data of 120 BCS patients who underwent various consecutive surgical treatments from July 2001 to October 2010 was analyzed. There were 82 male and 38 female patients, aging from 11 to 72 years with a mean age of (41 ± 13) years. All patients experienced various examinations to identify the pathological type of BCS. There were 5 cases of small hepatic veins type, 28 cases of large hepatic veins (LHV) type, 31 cases of inferior vena cava (IVC) type and 56 cases of combined obstruction of LHV and IVC. Totally, 25 patients experienced interventional treatment, include percutaneous transluminal angioplasty and/or stenting for stenosis of hepatic vein and/or IVC, 77 patients experienced open-thorax operation for BCS radical resection under protection of right atrium by-pass with extracorporeal circulation.

RESULTSTotally 97 cases were followed up from 1 to 120 months after various surgical treatment methods. Perioperative mortality was 6.2% (6/97). Follow-up period mortality was 8.2% (8/97). The restenosis of IVC and/or hepatic vein happened in 3 cases out of 25 cases in intervention treatment group in contrast with 15 cases out of 77 cases in radical resection group. The 5-year patency and survival rate of IVC/hepatic vein were 64.5% and 83.3%.

CONCLUSIONSThe surgical treatment of BCS need to get accurate diagnosis and pathological classification firstly, then, to choose appropriate therapeutic strategies based on individual pathological classification. The BCS radical resection can be an alternative method in some particular pathological classifications and the cases who failed in interventional treatment.

This study is to investigate the effect and mechanism of puerarin on DNA damage of HaCaT cells induced by UVB. Puerarin pre-treated cells were irradiated with UVB at 30 mJ x cm(-2). Twenty four hours after irradiation, DNA damage was detected by comet assay, ceramide was measured by thin layer chromatography and gas chromatography, intracellular free calcium ion was analyzed by flow cytometry, the phosphorylation level of p38 protein was examined by Western blotting method. Levels of DNA damage, ceramide, free calcium ion and p-p38 protein were elevated in UVB model cells. Contrary to the model group, all indicators above were reduced in all groups pre-treated by puerarin. Puerarin restrains the ceramide accumulation to block downstream p38 MAPK pathway and calcium ion rising, therefore reduces DNA damage in HaCaT cells induced by UVB.

OBJECTIVETo analyze and compare the characteristics of musculoskeletal ultrasonography and X-ray of knee osteoarthritis, and to investigate the advantages of them.

METHODSAccording to the inclusion and exclusion criteria, 57 cases (66 knees) were collected from February 2015 to May 2015. Among them, there were 48 females and 9 males with an average age of (58.9 +/- 9.8) years old (ranged, 41 to 78 years old). The main symptoms included unilateral or bilateral knee pain and locked joints explicit areas of tender points. The mean course of disease was (13.6 +/- 3.0) months. The results of musculoskeletal ultrasound and X-ray examinations were analyzed.

RESULTSAccording to Kellgren-Lawrence classification of knee joint on the X-ray: the musculoskeletal ultrasound results of patients with I degree synovial hyperplasia in 9 cases, joint effusion in 20 cases, meniscal disease in 13 cases, patellar pad inflammation in 5 cases, and patellar lesion in 8 cases. The musculoskeletal ultrasound results of patients with III degree: synovial hyperplasia in 20 cases,joint effusion in 31 cases, meniscal disease in 22 cases, patellar pad inflammation in 16 cases and patellar lesion in 17 cases. The musculoskeletal ultrasound results of patients with III degree: synovial hyperplasia in 6 cases,joint effusion in 6 cases, meniscal disease in 7 cases, patellar pad inflammation in 7 cases and patellar lesion in 5 cases.

CONCLUSIONThe musculoskeletal ultrasound can detect the pathological changes of knee soft tissue sensitively, provide an accurate location of lesions,and find lesions early. The musculoskeletal ultrasound should be applicated in the diagnosis of knee osteoarthritis.

OBJECTIVETo study soft tissue changes observed through musculoskeletal ultrasound (MSUS) in the treatment of knee osteoarthritis with needle-knife, so as to provide MSUS basis for needle-knife in the treatment of knee osteoarthritis.

METHODSForty patients with knee osteoarthritis treated in the Third Affiliated Hospital of Beijing University of Chinese Medicine from December 2011 to December 2012 were selected according to inclusion and exclusion criteria. All the patients were treated with needle-knife release method. The VAS scores and knee joint circumference were recorded before treatment and 2 weeks after treatment. The changes of knee joint hydrops articuli and joint synovial thickness were measured through MSUS.

RESULTSThe knee pain index was 6.850 +/- 1.417 before treatment and 2.790 +/- 1.299 after treatment;the index after treatment was lower than that of before treatment. The knee joint circumference was 407.320 +/- 45.151 mm before treatment and 391.240 +/- 41.129 mm after treatment; the knee joint circumference decreased after treatment. The amount of hydrops articuli observed by musculoskeletal ultrasound showed that 47 knees were cured, 19 knees improved and 2 knees failed. The synovial membrane thickness: 43 knees cured, 17 knees improved and 8 knees failed.

CONCLUSIONThe hydrops articuli and synovial thickness of knee joint of patients with knee osteoarthritis observed under the MSUS is consistent with the main symptoms and signs, which suggests that MSUS observation on soft tissue changes before and after needle knife in the treatment of knee osteoarthritis with high reliability.

OBJECTIVEThe purposes of this thesis were to study the behavior about workers exposed to dust and provide scientific basis for health promotion.

METHODSWe designed a questionnaire and carry it on the 746 dust workers in the 3 representative corporations of Machinery, Ceramic, and Metallurgy Industry. All data were input into computer. And a database was established with Excel. SPSS11.5 statistical analysis software was used to analyze the influence on protecting behavioral between the application of qualifications, different jobs, training or protection, and other aspects etc.

RESULTSThe rates were 94.4% and 75.3% about the regular physical examination and requirements for protective equipment. The rate of choosing an effective way of protection was generally low (15.4%). There was significant difference for among different educational background workers (P < 0.01). The rates of choosing an effective way of protection (20.3%), the regular physical examination (98.3%) and requirements for protective equipment (86.4%) in the dust workers who participated in the training of dust protection were superior than those who did not participated in the training. There was the significant difference (P < 0.05, P < 0.01). There was the significant difference for the rate of effective way of protection, regular physical examination, and requirements for protective equipment among the different corporations (P < 0.05).

CONCLUSIONSDust workers' using rate about the choosing an effective way of protection was generally low in Machinery, Ceramic, and Metallurgy Industry. Those who were not educated had a lower using rate about the protection behavior, regular physical examination, and requirements for protective equipment than those educated.
