Purpose To explore the role of expression of MMP-9 and MMP-13 in non-small cell lung cancer ( NSCLC) , and to investi-gate their association with the clinicopathologic feactures and prognosis of NSCLC. Methods The expression of MMP-9 and MMP-13 was detected in 88 NSCLC tissues and 18 adjacent normal tissues by immunohistochemistry SP method. Results The expression of MMP-9 and MMP-13 was higher in NSCLC than that in adjacent normal tissues (P<0. 05), which was positively correlated with dif-ferentiation and lymph node metastasis (P<0. 05). The expression of MMP-9 was positively correlated with age (P<0. 05), which was positively correlated with the expression of MMP-13 in NSCLC ( P <0. 05 ) . The survival rates in positive expression group of MMP-9 and MMP-13 were significantly lower than that of the negative expression group by log-rank method comparing survival curves (P<0. 05). Cox model analysis showed that the tumor size, lymph node metastasis and MMP-13 positive expression were closely relat-ed with the prognosis of NSCLC (P<0. 05). Conclusion MMP-9 and MMP-13 both are associated with the metastasis, invasion and prognosis of NSCLC, and MMP-13 may mainly activate MMP-9 to participate the invasion and metastasis of NSCLC.

[Objective]To assess the influence of three-dimensional computed tomography (3D CT) reconstruction on preoperative fracture classification of intraarticular fractures by comparing 3D CT and 2D CT in preoperative fracture classification of tibial plateau fractures and acetabular fractures.[Method]A retrospective study was performed to evaluate 28 tibial plateau fractures and 19 acetabular fractures.Four attending traumatic orthopaedic surgeons used 3D CT and 2D CT respectively to evaluate fractures and rendered fracture classification.Test of agreement was performed to evaluate interobserver and intraobserver agreement about fracture classification.[Result]With the use of 3D CT images,interobserver and intraobserver reliability for fracture classification increased to perfect agreement.[Conclusion]3D CT could improve the reliability of preoperative fracture classification for tibial plateau fractures and acetabular fractures.3D CT is helpful and worthwhile for preoperative evaluation for fracture classification of intraarticular fractures.

OBJECTIVETo investigate the application and effects of external fixator under the guidance of damage control therapy in limb open fracture.

METHODSFrom May 2008 to January 2013,72 cases with severe limb open fractures (Unincor- porated shock) were divided into control group and observation group (36 cases in each group). In observation group, 36 patients (including 22 males and 14 females) were treated by external fixator at stage I, as soon as possible after waiting for patients physiology conditions being stable,the stage II fracture operation was performed. In control group, 36 patients (24 males and 12 females) were treated by the first stage open reduction. The hospital admission time, open fracture severity score (OFSS),operation duration,operative blood loss,X-ray expose times, callus appear time, fracture healing time, postoperative infection rate, complications and Johner-Wruhs accceccment were recorded and evaluated.

RESULTSAll patients were followed up for 8 to 12 months (10.4 in averaged). The mean operation duration, operative blood loss, callus appear time, fracture healing time the mean operation duration reespectively were (56.79±8.87) min, (216.16±18.21) ml, (5.32±0.71) weeks, (12.79±2.52) weeks in observation group,and (104.53±9.28) min, (439.93±14.65) ml, (4.97±1.26) weeks, (14.81±2.63) weeks in control group. According to Johner-Wruhs acccecement,there were were 33 cases in excellent,2 in good,and 1 in poor in observation group,non-union of fracture in 1 case,local infection occurred in 1 cases; in control group 25 cases in excellent,6 in good, and 5 in poor, non-union of fracture in 1 case,local infection occurred in 8 cases. There were significant differences in operation duration, operative blood loss, callus appear time, fracture healing time, postoperative infection rate, complications (P<0.05). There were no significant differences in hospital admission time, open fracture severity score and X-ray expose times (P>0.05).

CONCLUSIONUnder the guidance of damage control therapy,using external fixator measures to treat patients with open fractures of limbs is worth popularizing in clinical application because it can shorten the operation time, less blood loss, reduce the infection rate and complications, improve the success rate of surgery and recovery rate.

Hip fracture patients preoperative and postoperative exist hidden blood loss which often affect patients' wound healing, increase the probability of infection, prolong rehabilitation exercise, influence postoperative effect. At the same time, the body's blood loss increase the activation of the blood clotting mechanism, promote the incidence of deep vein thrombosis, bleeding and deep vein thrombosis has become the main causes of high risk in hip operation. It is very important to stop bleeding, anticoagulation should not be ignored, so how to effectively deal with the prominent contradiction between the postoperative anticoagulation and bleeding or looking for a best balance has become a intractable problems in hip fracture treatment.

OBJECTIVE To analyze and evaluate the comsumption of the antibacterial drugs during surgery operation in our hospital objectively.METHODS To carry out statistical analysis of antibacterial drugs from May to Dec in 2007.RESULTS The 93 percent of preventive usage of antibacterial drugs were in 2 hours after operation.The most was cephalosporins.CONCLUSIONS It is important to enhance the education of rational use and supervision.

Objective To search for the methods preventing nephrotoxic injury of amikacin,Methods Case-control research was used in this study. There were 50 normal children in control group The urine routine, the ?2-microglobulin (?2 -M), mosmol and THP in urine and blood, the AIb, rGT and NAG in urine, the renal function and serum concentration of amikacin were determined respectively.The 43 patients with serious illness childten in study group, were divided into 2 groups (Group 1 and group 2 ). Group 1 (23 cases) was treated only with amikacin for 7 days, and group 2 (20 cases) was treated with vitaminC, vitamin E and amikacin for 7 days. Before treatment, the 3rd and 7th day during the treatment, all the items mentioncd above were examined in gtoup 1 and 2.Results The incidences of nephrotoxic injury of amikacin are 87 per cent (20/23)and 55 per cent (11/20) respectively in group 1 and 2. There is significant difference (P

Objective To explore the polysomnography(PSG) characteristice of obstructive sleep apnea hypopnea syndrome(OS-AHS) and primary snoring(PS) in children and clinical value of PSG in children with sleep disorders. Methods We analyzed 74 children with OSAHS and 62 with PS, every patient being monitored with PSG for 7 hours at night for 16 parameters, including apnea hypopnea index(AHI), periodic leg movement index(PLMI),and the lowest oxygen saturation(LSaQ2) etc. The parameters of the 2 groups were comparaed. Results Comparaed with PS group, there was statistically significant difference in parameters such as PLMI, AHI,LSaQ2,the moderate oxygen saturation(MSaO2).AHI in non- rapid eye movement (NREM)(P

Objective: To investigate the effects of acupuncture and combined acupuncture and medicine on the quality of life and the genital endocrine level in postmenopausal women. Methods:Forty-seven patients were randomly assigned to acupuncture and acupuncture plus medicine groups,23 cases in the acupuncture group and 24 cases in the acupuncture plus medicine group. The observed course of treatment was 3 months. A Chinese concise SF-36 questionnaire was used to evaluate the quality of life in the different groups of patients before and after treatment.Meanwhile, radioimmunoassay was used to observe the differences in serum genital hormones:follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) contents between pretreatment and posttreatment in both groups. Results: After treatment, there was a significant difference in quality of life between the two groups and it was better in the acupuncture plus medicine group than in the acupuncture group(P＜ 0.01). E2 content increased more markedly in the acupuncture plus medicine group than in the acupuncture group(P＜ 0.05). There were no significant differences in FSH and LH contents between the two groups (P ＞ 0. 05). Conclusion: Both acupuncture and acupuncture plus medicine can improve the quality of life and increase obviously low E2 content in postmenopausal women. Acupuncture plus medicine raises the patients' quality of life and E2 content more markedly than acupuncture. It is suggested that both acupuncture and acupuncture plus medicine can improve the symptoms, signs, and physical and mental health, raise the quality of life and ameliorate genital-endocrine environment in postmenopausal women, but a combination of acupuncture and medicine has a better effect.

Adaptive behavior is attracting more and more attention and have become necessary basis of diagnosis and intervention of mental retardation. The definition of adaptive behavior have not unified yet, AAMR(2002) suggests that adaptive behavior is the skill of concept, society and use, the constraint of adaptive behavior will influence individual's daily life, and then life adaption. Approachs of mental retardation assessment include interviews, behavioral observations, functional assessment, quality of life assessment and sociometric techniques. No matter which approach is used in assessment, the goal is to improve lives of individuals with mental retardation, the limits of each approach should be considered, and, the assessment of individuals with mental retardation must contain all aspects.
